    Classical biological control is often advocated as a tool for managing invasive species. However, accurate evaluations of parasitoid species complexes and assessment of host specificity are impeded by the lack of morphological variation. Here, we study the possibility of host races/species within the eulophid wasp Pediobius saulius, a pupal generalist parasitoid that parasitize the highly invasive horse-chestnut leaf-mining moth Cameraria ohridella. We analysed the population genetic structure, host associations and phylogeographic patterns of P. saulius in Europe using the COI mitochondrial gene. This marker strongly supports a division into at least five highly differentiated parasitoid complexes, within two of which clades with differing degrees of host specialization were found: a Balkan clade that mainly (but not only) attacks C. ohridella and a more generalist European group that attacks many hosts, including C. ohridella. The divergence in COI (up to 7.6%) suggests the existence of cryptic species, although this is neither confirmed by nuclear divergence nor morphology. We do not find evidence of host tracking. The higher parasitism rates observed in the Balkans and the scarcity of the Balkan–Cameraria haplotypes out of the Balkans open the possibility of using these Balkan haplotypes as biological control agents of C. ohridella elsewhere in Europe.

    The hypothesis whether exposure to certain infections protects from atopy remains equivocal. To further investigate this, we compared serologic markers of infection and allergic sensitization prevalence in Roma children, who live under unfavorable hygienic conditions that facilitate the spread of infections, and non-Roma children who live in the same area. Analyses included 98 Roma and 118 non-Roma children. Serum IgG antibodies for 13 foodborne- airborne- and bloodborne infectious agents were determined, and a cumulative index of exposure was calculated by adding one point for each positive infection. Specific serum IgE to certain common food- and aero-allergens was also tested. and positivity to any of them was defined as indication of atopy. Roma children were found significantly more seropositive for T. gondii, Hepatitis A, H. pylori, HSV-1, CMV, and Hepatitis B (p < 0.0001). Non-Roma children were found more seropositive for RSV and M. pneumonia (p < 0.0001). Regarding the overall prevalence of atopy or the specific IgE responses to the allergens tested, no statistically significant differences were found between Roma and non-Roma children. A positive association of the cumulative index of exposure to infections with atopy was found in the non-Roma children (OR: 1.38, 95% CI: 1.08-1.75, p = 0.01) and in the total population (OR: 1.42, 95% CI: 1.11-1.83, p = 0.01). Regarding the specific infectious agents tested, a statistically significant positive association of atopy with seropositivity was found for M. pneumoniae in the non-Roma children (OR: 3.93, 95% CI: 1.39) as well as in the total population studied (OR: 2.83, 95% CI: 1.32-6.07, p = 0.01). Despite the higher burden of exposure to the battery of the infectious agents tested among Roma children, no protective effect for allergic disease development was evident. On the contrary, a positive association of exposure to infections with evidence of atopy was found, especially evident in the non-Roma children.

    Background: The research and published literature on Roma health in Turkey is much more limited than in other European countries. Among these, there are hardly any published literature focusing on the health status, health indicators and health behaviors. Aims: The aim of this research is to describe the perceptions of health-related concepts and access and the use of health services and social determinants of the health of Roma people in Turkey. Study Design: Descriptive qualitative survey. Methods: The participants were chosen by random sampling. The semi-structured interview topic guide was developed from sources such as advice from the Romani community leaders, published evidence and personal experience from previous work with Roma communities. Non-directive open-ended questions allowed the exploration of their health status, how they conceptualize health and disease, their level of awareness on the impact of social determinants of health, on their health status and the access and use of health services. The data analysis was based on grounded theory. Analysis proceeded in four steps: 1. Reading and examining the transcripts separately using open coding, 2. Extracting the key words and codes from the transcripts and sorting them into categories, 3. Re-reading the transcripts by using selective coding, and 4. Examining the categories derived from the open coding systematically and determining the concepts summarizing the material. Results: The survey results are compatible with the existing literature on Roma health and reveal that 1) there is a tight link between the lack of social determinants of health and the poor health status of Roma people 2) socioeconomic factors and cultural norms of the ethnic minority are suspicious factors 3) comparative and systematic research is needed to illuminate the actual health gaps and causal factors for them. Conclusion: The research proves that the need for comparative and systematic research in Turkey to determine the

    Roma people in B&H are a marginalised population group. Their health condition; is considerably worse than the condition of other population groups. The health problems of Roma people correlate with inadequate living and dwelling conditions. Roma children are facing the impossibility of being health care beneficiaries, because their parents are unemployed. The objective of this survey was to examine the family surrounding of children in age up to 8 years, including the social conditions under which they live and the presence of health risk behaviour. The research presents a descriptive cross-section study. We interviewed 1100 non-Roma parents and children and 383 Roma parents and children (in the communities of domicile Roma people) in B&H Federation. The results obtained indicate that only 17,8 % of Roma parents are secondary-school leavers, while remaining percentage covers those with incomplete primary school or without education at all, against 63,6% of non-Roma parents who have secondary education. The parents consider themselves good providers for their children (59,3% of Roma parents and 75% of non-Roma parents often play with their children). The Roma parents seek for medical attention for their children only in the cases when urgent health problems occur, such as fever/increased body temperature (one-half of the interviewed parents) or diarrhoea (31,9%). Physical punishment of children occurs more frequently in Roma families (23,7% - this is only the top of an iceberg) then in non-Roma families (11,4%). The parents usually beat children by using their hands or punish them by flogging. The domestic violence is accepted amongst Roma people and it has most sever impact on children, who suffer emotionally and physically. In the future, it will be necessary to create the kind of family environment that would enable improvement of health condition and decrease the behaviour that endangers the health of children.

    The Roma, also known as 'Gypsies', represent the largest and the most widespread ethnic minority of Europe. There is increasing evidence, based on linguistic, anthropological and genetic data, to suggest that they originated from the Indian subcontinent, with subsequent bottlenecks and undetermined gene flow from/to hosting populations during their diaspora. Further support comes from the presence of Indian uniparentally inherited lineages, such as mitochondrial DNA M and Y-chromosome H haplogroups, in a significant number of Roma individuals. However, the limited resolution of most genetic studies so far, together with the restriction of the samples used, have prevented the detection of other non-Indian founder lineages that might have been present in the proto-Roma population. We performed a high-resolution study of the uniparental genomes of 753 Roma and 984 non-Roma hosting European individuals. Roma groups show lower genetic diversity and high heterogeneity compared with non-Roma samples as a result of lower effective population size and extensive drift, consistent with a series of bottlenecks during their diaspora. We found a set of founder lineages, present in the Roma and virtually absent in the non-Roma, for the maternal (H7, J1b3, J1c1, M18, M35b, M5a1, U3, and X2d) and paternal (I-P259, J-M92, and J-M67) genomes. This lineage classification allows us to identify extensive gene flow from non-Roma to Roma groups, whereas the opposite pattern, although not negligible, is substantially lower (up to 6.3%). Finally, the exact haplotype matching analysis of both uniparental lineages consistently points to a Northwestern origin of the proto-Roma population within the Indian subcontinent. PMID:26374132

  1. Securitarian healing: Roma mobility and health care in Rome.

    2015-01-01

    Over the last decade, Roma populations in Europe have been the object of strict securitarian policies. The Rome case is particularly interesting due to the continued shift from securitarian to humanitarian discourses and actions led by local institutions. The specific health care system implemented in the legal and illegal Roma camps was one of the tools used. The ethnographic fieldwork behind this article involved following the daily activities of a mobile medical unit dedicated to Roma camps in Rome and monitoring a health care project led by a nongovernmental organization. This analysis focuses on one particular dimension of precarious forms of Roma citizenship that the health care policies have developed to address Roma issues: the international mobility dynamics relating to health issues, which drive subjects into a forced integration of multiple, incomplete, and fragmentary medical approaches.

    The Roma people have specific values, therefore their views and beliefs about illness, dying and death are important to be known for health care providers caring for members of this community. The aim of this qualitative study based on 48 semi-structured interviews with Roma patients and caregivers in communities in two regions of Romania was to examine their selfdescribed behaviors and practices, their experiences and perceptions of illness, dying and death. Five more important themes about the Roma people facing dying and death have been identified: (1) The perception of illness in the community as reason for shame and the isolation that results from this, as well as the tendency for Roma people to take this on in their self image; (2) The importance of the family as the major support for the ill/dying individual, including the social requirement that family gather when someone is ill/dying; (3) The belief that the patient should not be told his/her diagnosis for fear it will harm him/her and that the family should be informed of the diagnosis as the main decision maker regarding medical treatment; (4) The reluctance of the Roma to decide on stopping life prolonging treatment; (5) The view of death as 'impure'. These results can be useful for health care providers working with members of the Roma community. By paying attention to and respecting the Roma patients' values, spirituality, and relationship dynamics, the medical staff can provide the most suitable healthcare by respecting the patients' wishes and expectations.

    The Roma are comprised of many founder groups of common Indian origins but different socio-cultural characteristics. The Vlax Roma are one of the founder Roma populations characterized by a period of bondage in the historic Romanian principalities, and by the archaic Romanian language. Demographic history suggests different migration routes of Roma populations, especially after their arrival in Mesopotamia and the eastern boundary of the Byzantine Empire. Although various genetic studies of uniparental genetic markers showed a connection between Roma genetic legacy and their migration routes, precise sampling of Roma populations elucidates this relationship in more detail. In this study, we analyzed mitochondrial DNA of 384 Croatian Vlax Roma from two geographic locations in the context of 734 European Roma samples. Our results show that Roma migration routes are marked with two Near-Eastern haplogroups, X2 and U3, whose inverse proportional incidence clearly separates the Balkan and the Vlax Roma from other Roma populations that reached Europe as part of the first migration wave. Spatial and temporal characteristics of these haplogroups indicate a possibility of their admixture with Roma populations before arrival in Europe. Distribution of haplogroup M35 indicates that all Vlax Roma populations descend from one single founder population that might even reach back to the original ancestral Indian population. Founder effects followed by strict endogamy rules can be traced from India to contemporary small, local communities, as in the case of two Croatian Vlax Roma populations that show clear population differentiation despite similar origins and shared demographic history.

    Abstract Roma populations’ low health status and limited access to health services, including primary care, has been documented in many European countries, and warrants specific health policies and practices. A variety of experiences shows how primary care can adjust its practices to reduce the barriers to primary care for Roma populations. At local level, establishing collaboration with Roma organisations helps primary care to improve mutual relations and quality of care. Mediation has proved to be an effective tool. Skills training of primary care practitioners may enhance their individual competences. Research and international sharing of experiences are further tools to improve primary care for the Roma people. PMID:27703542

    Objective The Roma minority represents the largest ethnic group in Central and South-East European countries. Data regarding the mortality in Roma hemodialysis subjects are limited. We evaluated the 3 year mortality of ESRD Roma patients treated with hemodialysis (HD). Study Design and Setting Our prospective cohort study included 600 ESRD patients on HD therapy recruited from 7 HD centers, from the main geographical regions of Romania. The median age of the patients was 56 (19) years, 332 (55.3%) being males, 51 (8.5%) having Roma ethnicity. Results Roma ESRD patients initiate dialysis at a younger age, 47.8 years vs. 52.3 years (P = 0.017), present higher serum albumin (P = 0.013) and higher serum phosphate levels (P = 0.021). In the Roma group, the overall 3 year mortality was higher when compared to Caucasians (33.3% vs. 24.8%). The multivariate survival analysis revealed that being of Roma ethnicity is an independent risk factor for mortality (HR = 1.74; 95% CI = 1.04–2.91; P = 0.035). Conclusions Roma patients with ESRD initiate HD therapy at a younger age as compared to Caucasians. They have a higher 3 year mortality rate and are dying at a younger age. Roma ethnicity represents an independent risk factor for mortality in our cohort. PMID:27196564

    The Roma, also known as gypsies or "tsinganoi," are amongst the oldest ethnic minorities in Europe. Nonetheless, they have been one of the most universally marginalized groups across all of the European nations. Their marginalization is evident in how Roma children have been treated in schools. Until recently, most nations have only offered them a…

    In its growth strategy for the coming decade, the EU recognises the Roma as one of several groups especially affected by poverty and social vulnerability. So far, many efforts to reverse this social exclusion have failed; imposed solutions based on power relations have ignored Roma voices and suggestions from the community. As a result, the EU now…

    2001-01-01

    Background Data provided by the social sciences as well as genetic research suggest that the 8-10 million Roma (Gypsies) who live in Europe today are best described as a conglomerate of genetically isolated founder populations. The relationship between the traditional social structure observed by the Roma, where the Group is the primary unit, and the boundaries, demographic history and biological relatedness of the diverse founder populations appears complex and has not been addressed by population genetic studies. Results Recent medical genetic research has identified a number of novel, or previously known but rare conditions, caused by private founder mutations. A summary of the findings, provided in this review, should assist diagnosis and counselling in affected families, and promote future collaborative research. The available incomplete epidemiological data suggest a non-random distribution of disease-causing mutations among Romani groups. Conclusion Although far from systematic, the published information indicates that medical genetics has an important role to play in improving the health of this underprivileged and forgotten people of Europe. Reported carrier rates for some Mendelian disorders are in the range of 5 -15%, sufficient to justify newborn screening and early treatment, or community-based education and carrier testing programs for disorders where no therapy is currently available. To be most productive, future studies of the epidemiology of single gene disorders should take social organisation and cultural anthropology into consideration, thus allowing the targeting of public health programs and contributing to the understanding of population structure and demographic history of the Roma.

    In Europe and specifically in Bulgaria, Roma represent the largest indigenous ethnic minority exposed to severe discrimination, social exclusion, poverty, and compromised well-being. To improve their conditions, identifying sources of psychological well-being for Roma is theoretically relevant and practically important. This study investigated the relation between ethnic, familial, and religious identities as salient collective identity components for psychological well-being among 194 Roma adolescents (age: M = 16.11 years, SD = 1.36) and their mothers (age: M = 35.95 years, SD = 3.54). The results indicated that in line with marginalization models of acculturation, Roma youth and their mothers showed a low endorsement of both Bulgarian mainstream and Roma ethnic identity. The average scores of well-being were also low. For both groups, familial identity was stronger compared to Roma, Bulgarian, and religious identity. A path model showed that collective identity was a positive predictor of well-being in both adolescents and mothers and that the mothers' collective identity was a predictor of adolescent well-being. Bulgarian mainstream identity had the strongest relationship with collective identity. It is concluded that, for Roma youth and their mothers, family is an important identity domain as it represents the most salient identification source that is not challenged in their environment.

    2009-01-01

    We describe an in vitro transcription-based method called ROMA (run-off transcription-microarray analysis) for the genome-wide analysis of transcription regulated by sigma factors and other transcriptional regulators. ROMA uses purified RNA polymerase with and without a regulatory protein to monitor products of transcription from a genomic DNA template. Transcribed RNA is converted to cDNA and hybridized to gene arrays allowing for the identification of genes that are specifically activated by the regulator. We discuss the use of ROMA to define sigma factor regulons in Bacillus subtilis and its broad application to defining regulons for other transcriptional regulators in various species. PMID:18948201

    Objectives The Roma people have been known in Europe for a 1000 years, during which they have usually been the subject of discrimination and oppression leading to isolation, powerlessness and poor health. The objective of this study is to investigate the sense of coherence (SOC) in relation to self-reported health among a group of Roma people in southwest Sweden. Study design A cross-sectional, quantitative pilot study. Methods A questionnaire was constructed based on the Short-Form Health Survey (SF-12) and Antonovsky's Sense of Coherence Scale (SOC-13) and was distributed among Roma people in southwest Sweden (n = 102). Self-reported health was summarised in a physical score (PCS) and a mental score (MCS). Comparisons were made with a general Swedish majority population and a Sami population. Results The health scores were significantly lower among the Roma people compared to Swedes – PCS: Roma 46.0 (Swedes 52.0) and MCS: Roma 47.5 (Swedes 52.6). The SOC score for the Roma people (54.4) was significantly lower than that of the Swedes (65.2) and Sami (65.0). Conclusions The low SOC with the Swedish majority society is a strong indication of the marginalisation and exclusion of the Roma people from mainstream society. Low scores in self-reported health among the Roma people also establishes the serious health risks the Roma people are experiencing through their present life situation. PMID:22584516

    2009-03-01

    Since Slovakia joined the European Union in 2004, Sheffield has seen a steady increase in the arrival of migrant workers and their families to the city. Most of these families are from a Roma background, marginalised within Eastern Europe and the subjects of recognised health inequalities in their country of origin. As newcomers to the UK, they have had no previous experience of the health visiting service or primary care provision. The impact of their migration on health services has been significant. As a vulnerable group, they consume a disproportionate amount of universal services. An understanding of their background and of their socioeconomic position in the UK is essential in determining their health needs. Attempts to address these effectively require good communication with both the public and voluntary sectors and the involvement of the community itself.

    Marginalised Roma communities in European countries live in substandard housing conditions the improvement of which has been one of the major issues of the Decade of Roma Inclusion, the ongoing intergovernmental European Roma programme. The paper presents EU-funded health impact assessments of national Roma housing policies and programmes in 3 Central and Eastern European countries in light of the evaluation of a completed local project in a fourth CEE country so as to compare predicted effects to observed ones. Housing was predicted to have beneficial health effects by improving indoor and outdoor conditions, access to services, and socioeconomic conditions. Negative impacts were predicted only in terms of maintenance expenses and housing tenure. However, observed impacts of the completed local project did not fully support predictions especially in terms of social networks, satisfaction with housing and neighbourhood, and inhabitant safety. In order to improve the predictive value of HIA, more evidence should be produced by the careful evaluation of locally implemented housing projects. In addition, current evidence is in favour of planning Roma housing projects at the local rather than at the national level in alignment with the principle of subsidiarity. - Highlights: Black-Right-Pointing-Pointer Predictive validity of HIA of national Roma housing policies - in light of current evidence - is low. Black-Right-Pointing-Pointer Implemented housing projects should be comprehensively evaluated to improve reliability of HIA. Black-Right-Pointing-Pointer Roma housing projects should be planned at the local rather than at the national level. Black-Right-Pointing-Pointer HIA should be used to plan Roma housing projects at the local level.

    On average, the Roma in Europe can expect to die 10 years earlier than the rest of the population, given the health conditions they experience. EU-funded research has informed on successful actions (SA) that when implemented among the Roma provide them new forms of educational participation which have a direct impact on improving their health status, regardless of their educational level. The findings from this research, unanimously endorsed by the European Parliament, have been included in several European Union recommendations and resolutions as part of the EU strategy on Roma inclusion. To analyze these SA, as well as the conditions that promote them and their impact on reducing health inequalities, communicative fieldwork has been conducted with Roma people from a deprived neighbourhood in the South of Spain, who are participating in the previously identified SA. The analysis reveals that these SA enable Roma people to reinforce and enrich specific strategies like improving family cohesion and strengthening their identity, which allow them to improve their overall health. These findings may inform public policies to improve the health condition of the Roma and other vulnerable groups, one goal of the Europe 2020 strategy for a healthier Europe.

    This study investigates intergeneration transmission of ethnic identity as a resource for life satisfaction of Roma adolescents and their parents. Historically, Roma represent the largest ethnic minority in Europe. They have been exposed to severe discrimination, social exclusion, and poverty. Therefore, identifying resources for their life satisfaction is theoretically and practically important. The present study included 1093 participants, of which there were 171 Roma adolescents (age: M = 14.96 years, SD = 1.85), 155 mothers (age: M = 36.16 years, SD = 5.77) and 123 fathers (age: M = 39.68 years, SD = 6.06). Further, a comparison group of 248 mainstream adolescents with their mothers (n = 221) and fathers (n = 175) was also included in the study. Adolescents and their parents provided data on ethnic identity (MEIM; Phinney, 1992) and life satisfaction (SWLS; Diener, Emmons, Larsen, & Griffin, 1985). Results indicated that Roma youth were lower on endorsement of ethnic identity and average on life satisfaction compared to their mainstream peers. A structural equation model showed that ethnic identity was a positive predictor of life satisfaction for both adolescents and their Roma parents. Furthermore, parents' ethnic identity was a predictor of adolescent life satisfaction. We concluded that for Roma youth and their parents, ethnic identity represents a salient source for life satisfaction and an intergenerational continuity of identity and life satisfaction exists.

    In many analyses of high-throughput data in systems biology, there is a need to quantify the activity of a set of genes in individual samples. A typical example is the case where it is necessary to estimate the activity of a transcription factor (which is often not directly measurable) from the expression of its target genes. We present here ROMA (Representation and quantification Of Module Activities) Java software, designed for fast and robust computation of the activity of gene sets (or modules) with coordinated expression. ROMA activity quantification is based on the simplest uni-factor linear model of gene regulation that approximates the expression data of a gene set by its first principal component. The proposed algorithm implements novel functionalities: it provides several method modifications for principal components computation, including weighted, robust and centered methods; it distinguishes overdispersed modules (based on the variance explained by the first principal component) and coordinated modules (based on the significance of the spectral gap); finally, it computes statistical significance of the estimated module overdispersion or coordination. ROMA can be applied in many contexts, from estimating differential activities of transcriptional factors to finding overdispersed pathways in single-cell transcriptomics data. We describe here the principles of ROMA providing several practical examples of its use. ROMA source code is available at https://github.com/sysbio-curie/Roma. PMID:26925094

    The European Roma represent a transnational mosaic of minority population groups with different migration histories and contrasting experiences in their interactions with majority populations across the European continent. Although historical genetic contributions of European lineages to the Roma pool were investigated before, the extent of contemporary genetic admixture between Bayash Roma and non-Romani majority population remains elusive. The aim of this study was to assess the genetic structure of the Bayash Roma population from northwestern Croatia and the general Croatian population and to investigate the extent of admixture between them. A set of genetic data from two original studies (100 Bayash Roma from northwestern Croatia and 195 individuals from the general Croatian population) was analyzed by Bayesian clustering implemented in STRUCTURE software. By re-analyzing published data we intended to focus for the first time on genetic differentiation and structure and in doing so we clearly pointed to the importance of considering social phenomena in understanding genetic structuring. Our results demonstrated that two population clusters best explain the genetic structure, which is consistent with social exclusion of Roma and the demographic history of Bayash Roma who have settled in NW Croatia only about 150 years ago and mostly applied rules of endogamy. The presence of admixture was revealed, while the percentage of non-Croatian individuals in general Croatian population was approximately twofold higher than the percentage of non-Romani individuals in Roma population corroborating the presence of ethnomimicry in Roma.

    In order to assure optimal care of patients with chronic illnesses, it is necessary to take into account the cultural factors that may influence health-related behaviors, health practices, and health-seeking behavior. Despite the increasing number of Romanian Roma, research regarding their beliefs and practices related to healthcare is rather poor. The aim of this paper is to present empirical evidence of specificities in the practice of healthcare among Romanian Roma patients and their caregivers. Using a qualitative exploratory descriptive design, this study is based on data gathered through three focus groups with 30 health mediators in the counties of Iasi and Cluj (Romania). We identified various barriers to access to healthcare for Roma patients: lack of financial resources and health insurance coverage, lack of cognitive resources or lack of personal hygiene, but also important cultural issues, such as the shame of being ill, family function, disclosure of disease-related information, patient's autonomy, attitudes towards illness and health practices, that should be considered in order to create a culturally sensitive environment in Romanian medical facilities:… The role of the health mediators within the context of cultural diversity is also discussed, as cultural brokers contributing to health care quality among Romanian Roma patients Bridging cultural differences may improve patient-healthcare provider relationships, but may have limited impact in reducing ethnic disparities, unless coupled with efforts of Roma communities to get involved in creating and implementing health policies.

    The purpose of this study was to explore access of Roma in South-Eastern Europe to sexual and reproductive health services. We conducted 7 focus group discussions with a total of 58 participants from Roma communities in Albania, Bulgaria and Macedonia. Our study revealed a number of barriers for Roma when accessing sexual and reproductive health services. Among the most important were the overall lack of financial resources, requests by health care providers for informal payments, lack of health insurance and geographical barriers. Health systems in the region seem to have failed to provide financial protection and equitable services to one of the most vulnerable groups of society. There is also a need for overcoming racial discrimination, improving awareness and information and addressing gender inequalities.

    The Roma (Gypsy) are the largest European minority population characterized by poverty, social exclusion as well as by numerous life-style and cultural specificities, which all could have an adverse impact on their cardiovascular health. This study assesses the prevalence of cardiovascular diseases (CVD) risk factors in community-based sample of 430 adult Roma, living in rural area of Croatia, by providing the actual and age-adjusted estimates using the European standard population. The most prominent classical CVD risk phenotypes (blood pressure, obesity, smoking, glucose and lipid profile) were selected, and the standard risk cut-offs were applied. The study has shown that compared to general population of Croatia, the Roma population bears a high CVD risk factors load related to smoking and high glucose level. The CVD risk factors prevalence in Roma also showed important sex and age patterns, the most imposing of which are the findings of higher prevalence of CVD risks in women (especially obesity and triglyceride levels) and the trend of higher body mass index (BMI) level in younger age group (18-34 years) which both stand in contrast to the trends characterizing the general population of Croatia. These findings are complemented by the trend of decreased risk in the oldest age group (65+ years) for all investigated CVD risk factors (with exception of triglycerides level) compared to the 50-64 age group. We conclude that the age and sex CVD risks pattern point to the health transition of this rural Roma population. As we expect the proportion of CVD in the Roma minority of Croatia to increase in the future along with further modernization of their lifestyle, the CVD prevention measures in this population are urgent and should be primarily targeted at women and at the younger segment of this population.

    Ovarian cancer is a common malignancy of the female reproductive system. Tumor markers serve as tools in the diagnosis of the disease. The aim of the present study was to determine the diagnostic value of sera levels of carbohydrate antigen-125 (CA-125), human epididymis protein 4 (HE4) as well as the area under the curve of the receiver operating characteristic (ROC) and the risk of ovarian malignancy algorithm (ROMA) index in ovarian cancer. The sera were measured using an electrochemiluminescence immunoassay on 158 individuals (64 patients with ovarian cancer, 64 with ovarian benign tumor and 30 healthy individuals) between September 2013 and May 2015. The results showed that levels of HE4 and CA-125 in the sera of the ovarian benign tumor group as well as their ROMA index were significantly higher (P<0.05) than those of the ovarian benign tumor and control groups, regardless of pre- or postmenopausal status. However, the level of CA-125 was significantly higher (P<0.05) in the ovarian benign tumor group compared with the healthy group, while the level of HE4 was similar in the two groups. The sensitivity of the ROMA index was higher (P<0.01) with detection of HE4 and CA-125. In the ovarian cancer group, the areas under ROC curves of ROMA, HE4 and CA-125 were 0.994, 0.990 and 0.941, respectively. The specificity and positive predictive value of HE4 in the premenopausal ovarian cancer group reached 98.36 and 95%, respectively. In conclusion, the results showed that the serum level of HE4 and the ROMA index are important indicators in the diagnosis of ovarian cancer. However, in addition to HE4 and CA-125 detection, the ROMA index is extremely valuable in improving the diagnostic efficiency of ovarian cancer. PMID:27347403

    Living in Roma settlements is associated with worse health in comparison with the majority population; this might be partially explained by socioeconomic disadvantages as well as cultural differences, including lifestyle. Eating habits represent an important part of lifestyle closely related to primary causes of morbidity and mortality, such as cardiovascular diseases, metabolic diseases or cancers. The eating habits of the population living in Roma settlements in comparison with those of the majority population were explored using the cross-sectional epidemiological HepaMeta study conducted in 2011. A representative sample of Roma (n = 452, mean age = 34.7; 35.2% men) and non-Roma (n = 403, mean age = 33.5; 45.9% men) aged 18-55 years living in the Kosice region were asked about breakfasting and recent consumption of fruits, vegetables, dairy products, meat products, meat, farinaceous dishes, and soft drinks. A logistic regression model was used separately for male and female participants. The population living in Roma settlements reported the recent consumption of fruit, vegetables and dairy products significantly less frequently in comparison with the majority population. Moreover, Roma females, in comparison with non-Roma females, reported significantly more frequently the consumption of meat and soft drinks. No differences were found between Roma and non-Roma in the consumption of meat products and farinaceous dishes. The population living in Roma settlements reported more frequently unhealthy eating habits in comparison with the majority population; this might contribute to worse health status of this population. The differences might be attributed to cultural differences between ethnic as well as socioeconomic groups, reduced availability of certain food items due to segregation or poverty and lower health literacy.

    To assess how specific population history, different migration routes, isolation, and endogamy practices contributed to the distribution of several rare diseases found in specific Roma groups, we conducted a population-based research study of rare disease mutations in Croatian Vlax Roma. We tested a total of 427 subjects from Baranja and Međimurje for the presence of four mutations causing hereditary motor and sensory neuropathy type Lom (HMSNL), GM1 gangliosidosis (GM1), congenital cataracts, facial dysmorphism and neuropathy (CCFDN), and limb girdle muscle dystrophy type 2C (LGMD2C), using the RFLP-PCR method to estimate carrier frequencies. We identified a total of four individuals heterozygous for the mutation causing HMSNL in the Baranja population, with a carrier rate amounting to 1.5%. Carriers for other three mutations causing GM1, CCFDN, and LGMD2C were not found in our sample. The carrier rate for the HMSNL mutation in Baranja is lower than in other Vlax Roma groups. In addition, distinct differences in carrier rates between the Croatian Vlax groups point to different genetic history, despite their belonging to the same Roma migration category and subgroup. The difference in carrier rates is either the result of admixture or the reflection of a greater extent of genetic drift since recent founding, maintained by a high degree of endogamy. PMID:24180318

The Roma/Gypsy population as an ethnic minority of Asian Indian origin is well known for its adverse health status with a high prevalence of obesity. The main aim of this study was to examine the contribution of the rs9939609 FTO polymorphism to the high prevalence of obesity in the Roma/Gypsy population. Following a number of anthropometric measurements, the FTO rs9939609 polymorphism was genotyped in 312 Roma/Gypsy individuals. We observed significant differences in body mass index (BMI), waist circumference, and waist-to-hip ratio between different genotypes (P = 0.003, P = 0.012, and P = 0.03, respectively). The waist circumference in the subjects with AA genotype was about 7.1 cm larger than in those with TT genotypes (P = 0.005). However, the strongest association of minor allele A of the rs9939609 FTO polymorphism was found with BMI (odds ratio, 1.55; 95% confidence interval, 1.129-2.128; P = 0.007), even after adjusting for age, sex, and smoking status. This study provides the first report of allele and genotype frequencies for the rs9939609 polymorphism and also the first evidence of the association of the FTO variant with obesity in the Roma/Gypsy population.

    2008-12-01

    ROMA (Rank-Ordered Multifractal Analysis) has the capabilities of deciphering the multifractal characteristics of intermittent fluctuations. The method allows one to understand the multifractal properties through global scale invariants. The utilities of ROMA, which combines the ideas of parametric rank ordering and single- parameter scaling of monofractals, were first demonstrated in its application to the results obtained from large-scale 2-D MHD simulations. In this study, we apply ROMA to the electric field fluctuations measured by the SIERRA sounding rocket in the auroral zone. The intermittent fluctuations span across time scales of multiple regimes that presumably reflect a change in the dominant physical processes. We extend the ROMA technique to take into account such nonlinear crossover behavior in the time scales, and obtain global scale invariants associated with the cross-regime multifractal spectra.

    An outstanding feature of marginalized Roma communities is their severely substandard living conditions, which contribute to their worse health status compared to the majority. However, health consequences of international and local-level housing initiatives in most cases fail to be assessed prospectively or evaluated after implementation. This paper summarizes the result of a retrospective health impact assessment of a Roma housing project in Hungary in comparison with the outcome evaluation of the same project. Positive impacts on education, in- and outdoor conditions were noted, but negative impacts on social networks, housing expenses and maintenance, neighbourhood satisfaction and no sustained change in health status or employment were identified. Recommendations are made to improve efficiency and sustainability of housing development initiatives among disadvantaged populations. PMID:20801071

    SUMMARY Objectives The objective of this paper is to provide information on indoor air quality and on the quality of the broader indoor environment of the houses in Roma villages in Slovakia and Romania and to discuss possible implications for health. Methods Indoor air was sampled in 11 houses in a Romanian Roma village and in 19 houses in a Slovakian Roma village. Levels of Carbon Monoxide (CO), Carbon Dioxide (CO2), total particulate matter (PM), temperature and humidity were measured. A questionnaire and a checklist were used to obtain additional information on the indoor environment and behavioural factors. We have sampled the same houses in winter and in summer. Results Levels of CO and CO2 were higher in winter in both countries as compared to summer. The limit value of 10 mg/m3 CO was exceeded in a few cases in both countries. In general, levels of CO, CO2 and PM were higher in Romania. Further environmental and behavioural hazards such as indoor smoking, pets inside or lack of ventilation were found. The reported self-perceived quality of the indoor environment was poor in many aspects. Conclusions Our findings of CO, CO2 and PM levels suggest that indoor air pollution in Roma settlements has the potential to be a health threat. The fact that the inhabitants spend a relatively long time inside the houses and that a number of additional environmental and behavioural hazards were identified by our study emphasizes the importance of the indoor air quality for health and thus priority attention should be paid to these issues by health authorities and researchers. Further research is essential and study designs must consider cultural background and specific characteristics of the community, especially in order to obtain valid data on health outcomes.

    We describe a new caprine form from the Upper Vallesian of La Roma 2 (Teruel Basin, Aragon). Aragoral mudejar Gen.n., sp.n. is close to the primitive forms of the Hippotraginae-Caprinae group. It differs from Norbertia hellenica by its more primitive dentition, the greater separation between the bases of the horn cores, the decreased thickness of the frontal bone and the relatively smaller size of the horn cores.

    The immunization strategy aimed to the elimination of Measles and the prevention of Congenital Rubella failed to reach the planned objectives in Europe; in Italy the renewed National Elimination Plan (PNEMoRc 2010-2015) has been recently approved. The evaluation of a preventive intervention to avoid the spread of measles in a Roma people camp confirm the importance of specific vaccination in high risk populations, like nomads, in which low coverage rates are responsible for the maintenance of the disease.

    Recent medical genetic research has identified a number of novel, or previously known, but rare conditions, caused by private founder mutations. The Finnish and Ashkenazi Jew populations provide the best examples for identifying genes in unique genetic disorders. In these populations, research efforts and high-level medical services resulted in intense improvements of medical care and in organization of population-based screening programs. Hereditary disorders of the Roma populations are known for a long time. The genetic background of these diseases has been established by extensive molecular genetic studies. The Romas represent 6% of the Hungarian population and live under extremely bad health conditions. Therefore, our aim was to map the incidence of the hereditary neuromuscular disorders among the Hungarian Roma population. Moreover, we intended to provide proper information, genetic counseling and possible prevention strategies for the families at risk, which should represent a primer task in public health. Because of our experience in neuromuscular disorders, we choose six, frequent, autosomal recessive disorders for these clinical and genetic studies: hereditary motor and sensory neuropathy type Lom (HMSNL), hereditary motor and sensory neuropathy type Russe (HMSNR), congenital cataracts facial dysmorphism syndrome (CCFDN), limb-girdle muscular dystrophy 2C (LGMD2C), congenital myasthenic syndrome (CMS) and spinal muscular atrophy (SMA). Following identification of the founder mutations, the possibility of prenatal diagnosis and carrier screening for family members will contribute to the decrease of the recurrence risk for these severe, mostly untreatable disorders.

    Learning and gaining knowledge of Roman history is an area of interest for students and citizens at large. This is an example of a subject with great sweep (with many interrelated sub-topics over, in this case, a 3,000 year history) that is hard to grasp by any individual and, in its full detail, is not available as a coherent story. In this paper, we propose a visual analytics approach to construct a data driven view of Roman history based on a large collection of Wikipedia articles. Extracting and enabling the discovery of useful knowledge on events, places, times, and their connections from large amounts of textual data has always been a challenging task. To this aim, we introduce VAiRoma, a visual analytics system that couples state-of-the-art text analysis methods with an intuitive visual interface to help users make sense of events, places, times, and more importantly, the relationships between them. VAiRoma goes beyond textual content exploration, as it permits users to compare, make connections, and externalize the findings all within the visual interface. As a result, VAiRoma allows users to learn and create new knowledge regarding Roman history in an informed way. We evaluated VAiRoma with 16 participants through a user study, with the task being to learn about roman piazzas through finding relevant articles and new relationships. Our study results showed that the VAiRoma system enables the participants to find more relevant articles and connections compared to Web searches and literature search conducted in a roman library. Subjective feedback on VAiRoma was also very positive. In addition, we ran two case studies that demonstrate how VAiRoma can be used for deeper analysis, permitting the rapid discovery and analysis of a small number of key documents even when the original collection contains hundreds of thousands of documents.

  6. The Prodigies of The Albano Lake During Roman Age and Natural Hazard Assessment At Roma, Italy.

    Funiciello, R.; Giordano, G.; de Rita, D.

    Roma is built just 20 km to the northwest of the Pleistocene Colli Albani volcano, but is believed not exposed to relevant natural hazards, except for the Tiber river flood- ings, and local amplification of seismic waves from distal earthquakes. This belief has generally induced modern historians and geologists to discard as SmythologicalT the & cedil;many references to natural prodigies that are reported by many Roman-age historians. Recent studies have demonstrated that the Albano maar, the youngest volcanic cen- tre of the Colli Albani volcano and presently filled by a 175 m deep lake, protracted its activity to the Holocene triggering several catastrophic lahar events, likely related to lake withdrawal, the deposits of which are exposed to the southwest of Roma and reach its periphery. This finding youngs the history of the volcano and makes it rele- vant to pre-historic settlements, which ScarefullyT avoided the Albano maar slopes up & cedil;to the Bronze age. What is still unknown, though, is whether the lake experienced such fluctuations and overspills during historic times. Several Roman authors such as Ti- tus Livius, Dionigi d'Alicarnasso, Plutarco, Germanico, and many others wrote about the then well known 398 BC prodigious event, when, during the war between Roma and the Etruscan city of Veio, the gods anger caused the sudden rise and overspill of the Albano lake, reported as unrelated to climatic events, and the destructive flooding of the countryside. After that event Romans actually built a tunnel-drain which still operates regulating the lake level at 293 m a.s.l., 70 m below the maar rim elevation. Should those chronicles be truthful, we can join the geologic observation of Holocene lahar deposits from lake withdrawal with historical lake withdrawals, reassessing the natural hazard for the city of Roma under a point of view never explored before. This paper carefully explores the historical credibility of the 398 BC lake overspill event and its

    This article examines the degree of integration of Roma and Gypsy children in formal education in the Peloponnese region of Greece. It is based on field research conducted by the University of Patras during the school year 2006/07 within the framework of the Greek Ministry of Education's "Integration of Roma children in school" programme, funded by the European Union. Despite governmental incentives for poor families to enrol their school-aged children, school attendance of Roma and Gypsy children was found to decline from primary year one to primary year six, with hardly any of them entering secondary school at all. Besides looking at school attendance figures and Roma and Gypsy children's proficiency in reading, writing and numeracy, this paper also considers gender, family composition, living conditions and economic situation, as well as culturally constructed perceptions of childhood and a person's life cycle. The aim of this article is to highlight the contradictions and ambiguities involved in the process of incorporating Roma and Gypsy children in formal education, and to evaluate their school performance and assess their academic choices.

    2012-01-01

    Background: Estimated number of the Roma people in central-eastern Europe cannot be precisely appreciated, but official data suggest that in the 2004 they were approximately 4.2 million. At this time, there are few available data about the health status of the Roma people, mostly assessing genetic and infectious diseases, which reflect poverty, overcrowding, and lack of education. There is even less data regarding non–communicable and chronic diseases, especially cardiovascular diseases. Methods: We searched the published literature on the cardiovascular risk factors in Roma people using PubMed from January 2000 to July 2011. The searching criteria were: (1) randomized, prospective observational, retrospective and meta-analysis; (2) adult patients with cardiac diseases or cardiovascular risk factors (3) data available for cardiovascular patients. Search terms included dyslipidemia, obesity, tobacco, hypertension, and diabetes mellitus. Results: Twenty-five studies were identified. Approximately 75% of them were related to just four countries: Slovakia, Croatia, Czech Republic, and Serbia. This paper is a review based on existing literature concerning classical risk factors in Roma people with emphasis on their ethnical features. Despite limited data, the results showed that this ethnicity has the incriminated risk factors more frequently than the majority and consequently a higher cardiovascular morbidity rate. Conclusions: Quantification of the cardiovascular risk factor and their implication in the shortening of life expectancy in Roma population was a provocation due to a paucity of reliable data. At this time, we should pay more attention on the Roma health issues and the cultural concerns that might affect them in the context of borderless Europe. PMID:23390466

    Intermittent fluctuations are the consequence of the dynamic interactions of multiple coherent or pseudo-coherent structures of varied sizes in the stochastic media (Chang, 1999). We briefly review here a recently developed technique, the Rank-Ordered Multifractal Analysis (ROMA), which is both physically explicable and quantitatively accurate in deciphering the multifractal characteristics of such intermittent structures (Chang and Wu, 2008). The utility of the method is demonstrated using results obtained from large-scale 2-D MHD simulations as well as in-situ observations of magnetic field fluctuations from the interplanetary and magnetospheric cusp regions, and the broadband electric field oscillations from the auroral zone.

    The paper discusses the necessity to bring environmental equity within the Pata Rât Roma community in Northwest Romania, relying on the answers to three questions: “Does environmental equity exist in Pata Rât?”, “How can it be attained?”, and “To what extent can it be brought to the targeted people?” It was shown how a trio of factors tailors the destiny of Roma inhabitants: being a minority, their ethnicity, and the fact they are living on and off what society rejects and dumps—a landfill. The framing of the environmental equity concerns within a vision considering negotiation as the most adequate means to attain it is a novel approach. Further on, the results of the study can fuel win-win solutions in environmental equity. The information abstracted from a set of indicators, assessed through an evaluation matrix, represents a beneficial platform for future bottom-up decisions concerning landfill residents. Three action options were analyzed: on-site living opportunities—that resulted to be preferred, off-site living opportunities, and “Do nothing”. The analysis provides qualitative evidence that the evaluation of environmental equity is largely subjective, because of its complexity and specificity related to geographical, historical, cultural characteristics, and political interests.

  13. Influence of refrigerated storage time on efficacy of irradiation to reduce Salmonella on sliced Roma tomatoes.

    2011-06-01

    Contamination of tomatoes with Salmonella is a recurring food safety concern. Irradiation is a nonthermal intervention that can inactivate pathogens on fresh and minimally processed produce. However, the influence of tomato processing protocols, including time in refrigerated storage and time between slicing and irradiation, has not been determined. Roma tomatoes were sliced and inoculated with a cocktail of Salmonella outbreak strains. The inoculated tomatoes were held in refrigerated storage for various times after inoculation to simulate the potential time delay between packaging and irradiation. Tomatoes were irradiated immediately (0 h) or after 24, 48, or 72 h in storage. The surviving populations were recovered and enumerated. Irradiation effectively reduced Salmonella at all times. The D(10)-values (the dose necessary for a 1-log reduction of the pathogen) were not significantly different at each storage time and ranged from 0.382 to 0.473 kGy. These results suggest that the time required for holding of processed Roma tomatoes or shipment to an off-site irradiation service provider will not alter the efficacy of irradiation in a commercial environment.

    The hallmark of nonlinear complexity phenomena in MHD and plasma turbulence is the appearance of intermittent fluctuating events. Such intermittent fluctuations are the results of the chaotic interactions of multiple coherent structures of varied sizes of the dynamical media. We discuss here a new method, the Rank-Ordered Multifractal Analysis (ROMA) that is both physically explicable and quantitatively accurate in deciphering the multifractal characteristics of intermittency. The generic character of the procedure provides a natural connection between the ROMA spectrum based on parametric rank ordering and the one- parameter scaling idea of monofractals. The properties of such multifractal spectra and their generalizations may be understood theoretically from the point of view of global scale invariants of coarse-graining transformations. We demonstrate the utility of the method using results obtained from large-scale 2D MHD simulations as well as in-situ observations of magnetic field fluctuations from the interplanetary and cusp/magnetosheath regions, and broadband electric field fluctuations from the auroral zone.

    Medical communication in Western-oriented countries is dominated by concepts of shared decision-making and patient autonomy. In interactions with Roma patients, these behavioral patterns rarely seem to be achieved because the culture and ethnicity have often been shown as barriers in establishing an effective and satisfying doctor-patient relationship. The study aims to explore the Roma's beliefs and experiences related to autonomy and decision-making process in the case of a disease with poor prognosis. Forty-eight Roma people from two Romanian counties participated in semi-structured interviews, conducted by a research team from the University of Medicine and Pharmacy of Iasi. Participants were recruited among the chronically ill patients and caregivers. The Roma community opposes informing the terminal patients about their condition, the "silence conspiracy" being widely practiced. The family fully undertakes the right of decision making, thus minimizing the patient's autonomy. We identified ethical dilemmas concerning autonomy, lack of patients' real decision-making power, and paternalistic attitudes exerted firstly by the family and, on demand, by the physician. Instead, the Roma patient benefits from a very active support network, being accompanied at the hospital by numerous relatives. The patient's right to make autonomous decisions promoted in the Western countries and stipulated by the Romanian law has diminished value in the Roma community. For the Roma, the understanding of dignity is not simply individual and personal, but it is closely related to their cultural particularities. Ignoring their cultural values could create conflicts between healthcare providers and community.

    Background During implementation of a community development project involving a severely disadvantaged Roma community, the community was threatened with eviction. Two scenarios, eviction with placement on the waiting list for social housing versus a replacement housing development, were identified and specified. A health impact assessment (HIA) was carried out to inform subsequent negotiations. Aims To assess the health effects of eviction in comparison with that of a housing project for a Roma community; to make recommendations on short‐term and long‐term benefits of the two scenarios in order to inform the local government; and to develop a demonstration HIA that can act as a model for other disadvantaged Roma populations. Method A prospective assessment, based on a broad model of health, was carried out to assess health effects of a housing project compared with eviction. By design, it ensured full involvement of members of the community, local decision makers and relevant stakeholders. Results and conclusion This HIA identified numerous positive and some probable negative health effects of a housing project. Despite the uncertainty around some of its predicted effects, the overall health benefit of a housing project clearly outweighed that of eviction. Although the immediate financial advantages of eviction for the municipal government are clear, this example provides further evidence to support the adoption of a statutory requirement to assess both economic and health outcomes. It also provides an example that other Roma communities can emulate. PMID:17933953

    We assessed the prevalence of HIV and selected blood-borne and sexually transmitted infections among a convenience sample of 64 residents of Dzsumbuj, a predominantly Roma (Gypsy) neighbourhood in Budapest, Hungary. No cases of HIV were detected, while the prevalence of Hepatitis B infection (anti-HBc) was 27% and syphilis prevalence was 2%. Romas (n=50) were significantly more likely than non-Romas (n=14) to have HAV antibodies (80% vs. 43%) and less likely to be HBV immunized (anti-HBs only; 6% vs. 29%). Current drug injectors (n=13) were more likely than non-injectors (n=51) to have antibodies against HAV (85% vs. 69%) and HCV (85% vs. 8%). While HIV has not been introduced in this population, risk conditions for a potentially explosive HIV epidemic are present. Health care policies should focus on expanding coverage for HAV and HBV immunizations, and access to HIV preventive services needs to be extended to marginalized, mostly minority populations, such as the Roma in Europe.

    The purpose of this work was to characterise the W24X mutation of the GJB2 gene in order to provide more representative and geographicaly relevant carrier rates of healthy Roma subisolates and the Hungarian population. 493 Roma and 498 Hungarian healthy subjects were genotyped for the GJB2 c.71G>A (rs104894396, W24X) mutation by PCR-RFLP assay and direct sequencing. This is the first report on GJB2 W24X mutation in geographically subisolated Roma population of Hungary compared to local Hungarians. Comparing the genotype and allele frequencies of GJB2 rs104894396 mutation, significant difference was found in GG (98.4 vs. 99.8 %), GA (1.62 vs. 0.20 %) genotypes and A (0.8 vs. 0.1 %) allele between the Roma and Hungarian populations, respectively (p < 0.02). None of the subjects of Roma and Hungarian samples carried the GJB2 W24X AA genotype. Considerable result of our study, that the proportion of GJB2 W24X GA heterozygotes and the A allele frequency was eight times higher in Roma than in Hungarians. Considering the results, the mutant allele frequency both in Roma (0.8 %) and in Hungarian (0.1 %) populations is lower than expected from previous results, likely reflecting local differentiated subisolates of these populations and a suspected lower risk for GJB2 mutation related deafness. However, the significant difference in GJB2 W24X carrier rates between the Roma and Hungarians may initiate individual diagnostic investigations and effective public health interventions.

    Summary Regulation of DNA replication and cell division is essential for tissue growth and maintenance of genomic integrity and is particularly important in tissues that undergo continuous regeneration such as mammary glands. We have previously shown that disruption of the KRAB-domain zinc finger protein Roma/Zfp157 results in hyperproliferation of mammary epithelial cells (MECs) during pregnancy. Here, we delineate the mechanism by which Roma engenders this phenotype. Ablation of Roma in MECs leads to unscheduled proliferation, replication stress, DNA damage, and genomic instability. Furthermore, mouse embryonic fibroblasts (MEFs) depleted for Roma exhibit downregulation of p21Cip1 and geminin and have accelerated replication fork velocities, which is accompanied by a high rate of mitotic errors and polyploidy. In contrast, overexpression of Roma in MECs halts cell-cycle progression, whereas siRNA-mediated p21Cip1 knockdown ameliorates, in part, this phenotype. Thus, Roma is an essential regulator of the cell cycle and is required to maintain genomic stability. PMID:27149840

    Background Despite the attention the situation of the Roma in Central and Eastern Europe has received in the context of European Union enlargement, research on their access to health services is very limited, in particular with regard to child health services. Methods 50 qualitative in-depth interviews with users, providers and policy-makers concerned with child health services in Bulgaria, conducted in two villages, one town of 70,000 inhabitants, and the capital Sofia. Results Our findings provide important empirical evidence on the range of barriers Roma children face when accessing health services. Among the most important barriers are poverty, administrative and geographical obstacles, low levels of parental education, and lack of ways to accommodate the cultural, linguistic and religious specifics of this population group. Conclusion Our research illustrates the complexity of the problems the Roma face. Access to health care cannot be discussed in isolation from other problems this population group experiences, such as poverty, restricted access to education, and social exclusion. PMID:19566936

    Curcuma longa (Zingiberaceae) is known for its uses in medicine, cosmetics, food flavouring and textile industries. The secondary metabolites of turmeric like essential oil, oleoresin and curcumin are important for its multipurpose uses. These traits of turmeric vary from place to place due to the influence of environment, soil and agro-climatic conditions. Here, we analyzed turmeric from different agroclimatic regions for influence of various factors on its growth and yield of important phytochemicals. A high curcumin yielding cultivar i.e., Roma was collected from high altitude research station, Koraput (HARS) and planted in nine agroclimatic regions of Odisha. Analysis of soil texture, pH, organic carbon, micro and macro nutrients were done from all the studied zones up to 2nd generation. Plants grown in their released station i.e., Eastern Ghat High Land showed 5% of curcumin and were taken as control. Plants grown in different agroclimatic zones showed a range of 1.4-5% of curcumin and 0.3-0.7% of rhizome essential oil and 0.3-1% of leaf essential oil content. Gas chromatography and mass spectra analysis showed tumerone and alpha phellandrene as the major compounds in all the zones with 10-20% variation. The present study will be immensely helpful for standardization and management of environmental and ecological factors for high phytochemical yield in turmeric plant.

    Rank-Ordered Multifractal Analysis (ROMA), a recently developed technique that combines the ideas of parametric rank ordering and one parameter scaling of monofractals, has the capabilities of deciphering the multifractal characteristics of intermittent fluctuations. The method retains the spirit of traditional structure function analysis and single-parameter scaling for monofractals, but differs as it enables one to understand the multifractal properties through rank-ordered scaling or non-scaling parametric variables. The ROMA technique is applied to analyze the multifractal characteristics of the auroral zone electric field fluctuations observed by the SIERRA sounding rocket. The observed fluctuations span across contiguous multiple regimes of scales with different multifractal characteristics. In this study, we discuss the idea of the ROMA technique and how it can take into account the crossover behavior --- with the possibility of collapsing probability distribution functions (PDFs) --- over these contiguous regimes.

    Vatastheela is a disease of Mutravahasrotasa, one among the 12 types of Mutraghata disorders elaborated by Sushruta in his seminal work, the Sushruta Samhita. Vatastheela, as described in Ayurveda, closely resembles benign prostatic hyperplasia (BPH) of modern medicine in its signs and symptoms. It is a senile disorder and chiefly affects individuals above the age of 40 years. The symptoms are those of bladder outflow obstruction, with increased frequency of micturition, dribbling, hesitancy, and the features of chronic urinary retention. Surgical management has been accepted as the standard management but is associated with many disadvantages as well as complications, which may not be acceptable at this age. Conservative management with modern medicines is also not free from side effects. So, in this age-group, there is a need for much safer alternative method of management. In this regard, many works have been carried out and shown that the Ayurvedic approach, using natural medicines, is a far better approach. We carried out a comparative study of Mahayavanala Roma Kshara (MRK) and Dhanyaka Gokshura Ghrita (DGG), which are the compounds prescribed for Mutraghata in Ayurvedic literature. The patients were randomly selected from the OPD and IPD of IPGT and RA hospital, Jamnagar, Gujarat, and divided into two groups. In first group, one (500 mg) capsule of MRK was given twice a day with lukewarm water for 45 days; in second group, 10 gm of DGG was given orally twice a day with lukewarm water for 45 days. DGG showed significantly greater relief in the subjective parameters as per International Prostate Symptoms Score (IPSS) than MRK. However, reduction in the size of the prostate and in the volume of the post-void residual urine was found much better in the MRK group. PMID:22131735

    Roma communities represent the main involved actors in the informal activities in the Balkan regions, especially because the state does not formally recognize them as formal inhabitants. The Roma community in Zavidovici, despite being resident since the beginning of the 20th century, is still considered a marginalized and vulnerable group. They are actively involved in and dependent on the informal solid waste sector. Waste collection is a 'family business', a kind of self-employment and the main source of income for households. Informal recyclers have a central role in the solid waste management system and they recover a significant amount of materials, especially iron, copper, brass, lead and exhausted batteries. Despite the negative fluctuations of the raw material prices, because of the international economic crisis, informal recyclers remain dependent on the waste recycling sector. They are crucial actors in the value chain of recyclables: though they cannot access the final buyers of recyclables, they provide more than 50% of the market to the middle dealers in the Zenica-Doboj Canton. This research activity consists of a deep socio-economic analysis of the informal recyclers' community living in Zavidovici city. In particular, this paper describes the composition and welfare status of informal recyclers' households, the role of informal recyclers in waste collection, the geographical coverage and the related pattern of waste picking, types, volumes and price fluctuations of recyclable materials, and the middle dealers involved in the informal recycling system.

    Previous genetic studies, supported by linguistic and historical data, suggest that the European Roma, comprising a large number of socially divergent endogamous groups, may be a complex conglomerate of founder populations. The boundaries and characteristics of such founder populations and their relationship to the currently existing social stratification of the Roma have not been investigated. This study is an attempt to address the issues of common vs independent origins and the history of population fissioning in three Romani groups that are well defined and strictly endogamous relative to each other. According to linguistic classifications, these groups belong to the Vlax Roma, who account for a large proportion of the European Romani population. The analysis of mtDNA sequence variation has shown that a large proportion of maternal lineages are common to the three groups. The study of a set of Y chromosome markers of different mutability has revealed that over 70% of males belong to a single lineage that appears unique to the Roma and presents with closely related microsatellite haplotypes and MSY1 codes. The study unambiguously points to the common origins of the three Vlax groups and the recent nature of the population fissions, and provides preliminary evidence of limited genetic diversity in this young founder population.

    The aim was to assess the health-related quality of life (HRQL) of the Roma and further to detect the significant determinants that are associated with their HRQL. The cross-sectional study involved 1068 Roma adults living in settlements (mean age 36). HRQL was measured by the Greek version of SF-36 Health Survey and further socio-demographic characteristics (sex, age, marital status, education, permanent occupation etc.) and housing conditions (stable housing, access to basic amenities such as drinkable water, drainage, electricity which compose material deprivation) were involved. Non parametric tests and multiple linear regression models were applied to identify the factors that have significant association with HRQL. After controlling for socio-demographic characteristics, health status and housing conditions, sex, age, education, chronic diseases, stable housing and material deprivation were found to be significant determinants of the Roma's HRQL. Men reported significantly better health than women as well as those who attended school compared to the illiterate. Chronic diseases were remarkably associated with poor HRQL from 10 units in MH (Mental Health) to 34 units in RP (Role Physical). Material deprivation was related to lower GH (General Health), and VT (Vitality) scores and higher RP (Role Physical) and RE (Role Emotional) scores. Chronic conditions and illiteracy are two key areas that contribute significantly to worse HRQL. Policies should be part of a comprehensive and holistic strategy for the Roma through intervention to education, housing and public health.

    Introduction Roma (Gypsies), the largest and most disadvantaged ethnic minority group in Europe, are believed to be vulnerable to HIV/AIDS. This study’s aim was to examine HIV risk in 6 Roma male sociocentric networks (n=405 men) in Bulgaria. Methods Participants were interviewed concerning their risk practices and tested for HIV/STDs. Results High-risk sexual behaviors were common. Over 57% of men had multiple sexual partners in the past 3 months. Over one-third of men reported both male and female partners in the past year. Condom use was low. Greater levels of sexual risk were associated with lower intentions and self-efficacy for using condoms, drug use, having male partners, knowing HIV-positive persons, and having higher AIDS knowledge but no prior HIV testing. Two men had HIV infection, 3.7% gonorrhea, and 5.2% chlamydia. Discussion HIV prevention interventions directed toward high-risk social networks of Roma are needed before HIV infection becomes more widely established. PMID:22370730

    The Colli Albani is the quiescent volcano that dominates the southwestern skyline of Roma (Italy). The last eruption occurred during the Holocene, from the eccentric Albano maar, along its western slope. The volcano is presently affected by cyclic seismic swarms, ground uplift and diffuse CO 2 degassing. The degassing has caused several deadly incidents during the last years and constitutes a major civil protection concern, as the volcano slopes are densely inhabited. Nevertheless, the volcano does not have a permanent monitoring network, and the background level and anomalous CO 2 levels, the relationship between the gas release and the seismic and ground deformation activity at the Colli Albani are still to be defined. The aim of this work is to define the historical record of CO 2 release. Evidences of deep CO 2 periodic release during the last 2000 years in the area of Colli Albani volcano (Roma, Italy) are offered from speleothems studies. A Roman-age stone mine, now used for mushroom cultivation, is decorated with actively growing speleothems, characterised by depositional hiatuses. Different levels of four stalactites, separated by depositional unconformities, and several samples from a single depositional cycle belonging to a stalagmite have been dated by U/Th method and analysed for their O and C isotopic composition. Eight cycles of deposition have been identified from 90-110 A.D. to 1350-1370 A.D., some of which are recognised across different speleothems. The age gap dividing different growth layers is in the order of one to few hundred years giving a temporal span for periodic interruption of speleothems deposition. O and C isotopic analyses performed on the samples collected from a single cycle (the oldest) have shown that the composition of the mother solutions was initially mainly meteoric and that a progressive increase in the input of a deep component rich in CO 2 (up to a proportion of 20-30%) occurred just before the interruption of the

    Objectives To evaluate the validity and compare the performance of cancer antigen-125 (CA-125), human epididymis protein 4 (HE4), the risk of malignancy index (RMI), and the risk of ovarian malignancy algorithm (ROMA) in the diagnosis of ovarian cancer in patients with ovarian lesions discovered during their preoperative work-up investigations. Methods This prospective, cross-sectional study looked at patients who attended the gynecology department at the Royal Hospital, Muscat, from 1 March 2014 to 30 April 2015, for the evaluation of an ovarian lesion. The inclusion criteria included women who underwent surgical intervention and who had a preoperative pelvic ultrasound with laboratory investigation for CA-125 and HE4. The study validated the diagnostic performance of CA-125, RMI, HE4, and ROMA using histopathological diagnosis as the gold standard. Results The study population had a total of 213 cases of various types of benign (77%) and malignant (23%) ovarian tumors. CA-125 showed the highest sensitivity (79%) when looking at the total patient population. When divided by age, the sensitivity was 67% in premenopausal women. In postmenopausal women, CA-125 had lower sensitivity (89%) compared to RMI, HE4, and ROMA (93% each). A high specificity of 90% was found for HE4 in the total patient population, 93% in premenopausal women and 75% in postmenopausal women. CA-125 had the highest specificity (79%) in postmenopausal women. Both CA-125 and RMI were frequently elevated in benign gynecological conditions particularly in endometriosis when compared to HE4 and ROMA. We also studied modifications of the optimal cut-offs for the four parameters. Both CA-125 and RMI showed a significant increase in their specificity if the cut-off was increased to ≥ 60 U/mL for CA-125 and to ≥ 250 for RMI. For HE4, we noted an improvement in its specificity in postmenopausal women when its cut-off was increased to140 pmol/L. Conclusions HE4 and ROMA showed a very high specificity

    Within the PanGeo project (financed by the European Commission under the 7th Framework Program), the Geological Survey of Italy ( ISPRA) and the Urban Planning Department of the City of Roma developed a geodatabase and map of the geological hazards for the territory of Roma, integrating remotely sensed data (PSInSAR—Permanent Scatterer Interferometry Synthetic Aperture Radar) and in situ geological information. Numerous thematic layers, maps and inventories of hazards (e.g., landslides, sinkholes, cavities), geological and hydrogeological data added to historical and recent urbanization information were compared to the permanent scatterer (PS) data from the European Remote Sensing satellites (ERS-1/2, 1992-2000) and ENVISAT (2002-2005) descending scenes, in order to produce a ground stability layer (GSL). Based on the PS data, most of the territory appears stable (almost 70 % of PS velocities are within ±1 mm/year). About 14 % of the PSs show positive line-of-sight (LOS) velocities (measured along the LOS of the satellite) between 1 and 3 mm/year and more than 2 % exceed 3 mm/year; more than 11 % of PSs show negative LOS velocities between -1 and -3 mm/year, while about 3 % exceed -3 mm/year (with tens of the PSs showing velocities over -20 mm/year). The GSL is comprised of polygons or multi-polygons (multipart polygons grouping individual polygons under a single identifier geohazard) enclosing areas where geohazards have been pointed out by PS data and/or in situ surveys (observed instabilities), and by polygons enclosing areas potentially affected by geohazards, based on the available knowledge of the territory (potential instabilities). In Roma's GSL, 18 multi-polygons (covering ca. 600 km2) related to observed instabilities have been outlined, where ground movements could be detected through InSAR data or where landslides and sinkholes are known to have occurred. Other 13 multi-polygons (covering nearly 900 km2) concern areas where the potential occurrence

    In chronic diseases the adherence and persistence to therapeutic treatments are often lower than guidelines said. This leads to a worse therapeutic effect of the treatments and to a misuse in healthcare costs. Our study evaluates the impact of a pharmacoutilization analysis model, derived from the administrative database of the Local Health Unit Roma B. In particularly we calculate some indicators of adherence, persistence, occasional treatment and switch in patients on statins secondary prevention treatment (patients discharged from Hospital with Acute Myocardial Infarction diagnosis). The model that we developed would be successfully used in the cost-effective analysis of other drugs. PMID:21132042

    A new method in describing the multifractal characteristics of intermittent events was introduced by Cheng and Wu [Chang T. and Wu C.C., Physical Rev, E77, 045401(R), 2008]. The procedure provides a natural connection between the rank-ordered spectrum and the idea of one-parameter scaling for monofractals. This technique has been demonstrated using results obtained from a 2D MHD simulation. It has also been successfully applied to in-situ solar wind observations [Chang T., Wu, C.C. and Podesta, J., AIP Conf Proc. 1039, 75, 2008], and the broadband electric field oscillations from the auroral zone [Tam, S.W.Y. et al., Physical Rev, E81, 036414, 2010]. We take the next step in this procedure. By using the ROMA spectra and the scaled probability distribution functions (PDFs), raw PDFs can be calculated, which can be compared directly with PDFs from observations or simulation results. In addition to 2D MHD simulation results and in-situ solar wind observation, we show clearly using the ROMA analysis the multifractal character of the 3D fluid simulation data obtained from the JHU turbulence database cluster at http://turbulence.pha.jhu.edu. In particular, we show the scaling of the non-symmetrical PDF for the parallel-velocity fluctuations of this 3D fluid data.

    The potential of Salmonella population to rebound on non-washed and washed roma tomatoes and jalapeño peppers in humid storage at 4°C, 10°C, 15°C, 21°C, or 35°C for ≤12 days was investigated. The initial inoculation levels of Salmonella on peppers and tomatoes were 5.6 and 5.2 log CFU/cm(2), respectively. Air-drying of fruit surfaces resulted in contamination levels of 3.9 and 3.7 log CFU/cm(2) on inoculated peppers and tomatoes, respectively. At 21°C and 35°C, the levels of air-dried Salmonella inoculums on produce surfaces increased ≥2 log cycles, with the most rapid growth in the first 3 days. Mechanical washing on rollers (rinsing; R-treatment) or revolving brushes (rinsing and brushing; RB-treatment) with water decreased Salmonella counts by ≥2.5 log CFU/cm(2) on both peppers and tomatoes. After R- or RB-treatment, peppers stored at 21°C and 35°C permitted residual Salmonella (≤1.4 log CFU/cm(2)) to grow to 2.6-3.9 log CFU/cm(2). During storage, residual Salmonella (≤1.0 log CFU/cm(2)) on washed tomatoes increased to 3.1 log CFU/cm(2) at 35°C following R-treatment and 3.8 log CFU/cm(2) at 21°C following RB-treatment. Cold storage at 4°C and 10°C effectively prevented the proliferation of Salmonella on both washed and non-washed produce. The current study on jalapeño peppers and roma tomatoes demonstrated that Salmonella population can rebound on produce in humid storage before or after washing. The finding highlights the benefit of uninterrupted cold storage for safer produce operations.

    Remote sensing data play an important role for the environmental monitoring because they allow to provide systematic information on very large areas and for a long period of time. Such information must be analyzed, validated and incorporated into proper modeling tools in order to become useful for performing risk assessment analysis. These approaches has been already applied in the field of natural hazard evaluation (i.e. for monitoring seismic, volcanic areas and landslides). However, not enough attention has been devoted to the development of validated methods for implementing quantitative analysis on civil structures. This work is dedicated to the comprehensive utilization of ERS / ENVISAT data store ESA SAR used to detect deformation trends and perform back-analysis of the investigated structures useful to calibrate the damage assessment models. After this preliminary analysis, SAR data of the new satellite mission (ie Cosmo SkyMed) were adopted to monitor the evolution of existent surface deformation processes and to detect new occurrence. The specific objective was to set up a data processing and data analysis chain tailored on a service that sustains the safe maintenance of the built-up environment, including critical construction such as public (schools, hospital, etc), strategic (dam, highways, etc) and also the cultural heritage sites. The analysis of the test area, in the southeastern sector of Roma, has provided three different levels and sub-levels of products from metropolitan area scale (territorial analysis), settlement scale (aggregated analysis) to single structure scale (damage degree associated to the structure).

    During a survey of human saliva by a top-down reversed-phase high-performance liquid chromatography with electrospray ionization mass spectrometry approach, two proteins eluting at 27.4 and 28.4 min, with average masses of 15 494 ± 1 and 11 142 ± 1 Da, were detected in a subject from Boston. The Δmass value (4352 Da) of the two proteins was similar to the difference in mass values between intact (150 amino acids, [a.a.]) and truncated acidic proline-rich proteins (aPRPs; 106 a.a.) suggesting an a.a. substitution in the first 106 residues resulting in a strong reduction in polarity, since under the same experimental conditions aPRPs eluted at ~22.5 min (intact) and 23.5 min (truncated forms). Manual inspection of the high-resolution high-performance liquid chromatography with electrospray ionization tandem mass spectra of the truncated isoform showed the replacement of the phosphorylated Ser-22 in PRP-3 with a Phe residue. Inspection of the tandem mass spectra of the intact isoform confirmed the substitution, which is allowed by the code transition TCT→TTT and is in agreement with the dramatic increase in elution time. The isoform was also detected in two other subjects, one from Boston (unrelated to the previous) and one from Rome. For this reason we propose to name this variant PRP-1 (PRP-3) RB (Roma-Boston) Ser22(phos)→Phe. PMID:24771659

    A case of a young man diagnosed with perianal nodular melanoma with a gene mutation, accompanied by regional and pulmonary metastases on initial presentation, and later on with hepatic and bone involvement, is presented. The patient underwent wide local excision but was unresponsive to dacarbazine. Targeted therapy with vemurafenib had shown clinical improvement for a 5-month duration until he showed signs of disease progression. Just after the shift of adjuvant therapy to ipilimumab, he was diagnosed with multiple cerebral metastases that eventually led to his demise 6 months after initiation of vemurafenib, having had a 12-month survival period from the time of initial melanoma diagnosis.

    This study shows the direct effect of atmospheric particulate matter on plant growth. Tomato (Solanum lycopersicum L.) plants were grown for 18d directly on PM10 collected on quartz fiber filters. Organic and elemental carbon and polycyclic aromatic hydrocarbons (PAHs) contents were analyzed on all the tested filters. The toxicity indicators (i.e., seed germination, root elongation, shoot and/or fresh root weight, chlorophyll and carotenoids content) were quantified to study the negative and/or positive effects in the plants via root uptake. Substantial differences were found in the growth of the root apparatus with respect to that of the control plants. A 17-58% decrease of primary root elongation, a large amount of secondary roots and a decrease in shoot (32%) and root (53-70%) weights were found. Quantitative analysis of the reactive oxygen species (ROS) indicated that an oxidative burst in response to abiotic stress occurred in roots directly grown on PM10, and this detrimental effect was also confirmed by the findings on the chlorophyll content and chlorophyll-to-carotenoid ratio.

    Experiments were conducted to determine the respiration rate of tomato at 10, 20 and 30 °C using closed respiration system. Oxygen depletion and carbon dioxide accumulation in the system containing tomato was monitored. Respiration rate was found to decrease with increasing CO2 and decreasing O2 concentration. Michaelis-Menten type model based on enzyme kinetics was evaluated using experimental data generated for predicting the respiration rate. The model parameters that obtained from the respiration rate at different O2 and CO2 concentration levels were used to fit the model against the storage temperatures. The fitting was fair (R2 = 0.923 to 0.970) when the respiration rate was expressed as O2 concentation. Since inhibition constant for CO2 concentration tended towards negetive, the model was modified as a function of O2 concentration only. The modified model was fitted to the experimental data and showed good agreement (R2 = 0.998) with experimentally estimated respiration rate.

    Effects of Xylopia aethiopica (Dunal) A. Richard aqueous extract on the antioxidants of matured tomato fruits at red stage were investigated at 13 ± 2 °C and 80 ± 5 % relative humidity. A sample treated with sodium bicarbonate and untreated samples were included. Samples packaged in low density polyethylene (30 μm thickness) bags were analysed at intervals of 5 days. The treatments revealed statistically significant differences in ascorbic acid content of stored tomato fruits. Fruits treated with 5 % X. aethiopica on day 5 of storage had 21.0 mg/100 g which was significantly (p < 0.05) higher than 18.2 mg/100 g in untreated control samples. At 15th day of storage, ascorbic acid was 10.0 and 14.2 mg/100 g in tomato fruits treated with sodium bicarbonate and 5 % X. aethiopica respectively. The carotenoid and lycopene contents were lower in sodium bicarbonate-treated and the untreated control samples than in X. aethiopica-treated sample. The total phenolic contents were better retained in X. aethiopica-treated tomato than in control. Treatment of tomato fruits with X. aethiopica at 4 & 5 % levels significantly retained the qualities evaluated. PMID:25745258

    Purpose: This prospective, phase 2 study aimed at assessing the efficacy of accelerated fractionation radiation therapy by concomitant boosts (CBs) associated with chemoradiation therapy (CRT) of the whole pelvis, in improving the rate of pathological complete response (pCR) to treatment in patients with International Federation of Gynaecology and Obstetrics (FIGO) stage IB2-IVA locally advanced cervical cancer. Methods and Materials: Neoadjuvant CRT included conformal irradiation of the whole pelvis with a total dose of 39.6 Gy (1.8 cGy/fraction, 22 fractions), plus additional irradiation of primary tumor and parametria with 10.8 Gy administered with CBs (0.9 cGy/fraction, 12 fractions, every other day). Concomitant chemotherapy included cisplatin (20 mg/m{sup 2}, days 1-4 and 26-30 of treatment), and capecitabine (1300 mg/m{sup 2}/daily, orally) during the first 2 and the last 2 weeks of treatment. Radical hysterectomy plus pelvic with or without aortic lymphadenectomy was performed within 6 to 8 weeks from CRT. Toxicity was recorded according to Radiation Therapy Oncology Group toxicity criteria and Chassagne grading system. Based on the Simon design, 103 cases were required, and the regimen would be considered active if >45 pCR were registered (α error = 0.05; β error = 0.1). Results: pCR was documented in 51 cases (50.5%), and the regimen was considered active, according to the planned statistical assumptions. At median follow-up of 36 months (range: 7-85 months), the 3-year local failure rate was 7%, whereas the 3-year disease-free and overall survival rates were 73.0% and 86.1%, respectively. Grade 3 leukopenia and neutropenia were reported in only 1 and 2 cases, respectively. Gastrointestinal toxicity was always grade 1 or 2. Conclusions: Addition of CBs in the accelerated fractionation modality to the whole pelvis chemoradiation followed by radical surgery results in a high rate of pathologically assessed complete response to CRT and a very encouraging local control rate, with acceptable toxicity.

    The monitoring of urban areas and man-made structures is of key importance for the preservation of artistic, archaeological and architectural heritage. In this context, the remote sensing techniques may allow non-invasive analysis of large areas by exploiting long time series of satellite data. Among these techniques, the Synthetic Aperture Radar (SAR) Interferometry (InSAR) has already demonstrated to be an effective tool for monitoring the displacements occurring in the historical and artistic heritage located in the historical city centers. As a matter of fact, the InSAR technique allows producing spatially dense deformation maps with centimeter to millimeter accuracy, by exploiting the phase difference (interferogram) of temporally separated SAR images relevant to the same analyzed area. In order to guarantee the monitoring of urban area displacements, it is strategic to provide very long term deformation time series by also exploiting SAR data acquired by different sensors. Accordingly, ERS/ENVISAT data archive, providing acquisitions spanning the 1992-2010 time period, might allow us generating very long term deformation time-series. However, an ERS/ENVISAT data combination is limited by the two sensors slightly different carrier frequencies: 5.331 GHz for the ENVISAT sensor and 5.3 GHz for the ERS one. Therefore, because the interferometric phase is dependent on the radiation wavelength, the generation of conventional ERS/ENVISAT cross-interferograms is strongly affected by the induced decorrelation effects. In this work we show the effectiveness of the Small BAseline Subset (SBAS) (Berardino et al., 2002; Lanari et al., 2004) approach for the conservation, monitoring and risk prevention of cultural heritage. Indeed, the SBAS technique allows us to produce deformation time series at the scale of the single building by processing very long sequences of ERS-1/2 and ENVISAT (IS2 swath) SAR data, acquired with the same illumination geometry. In particular, the SBAS approach exploits only conventional ERS/ERS and ENVISAT/ENVISAT differential interferograms, in order to limit the decorrelation effects and improve the number of the detected coherent points. Accordingly, this method may play a key role for supporting the study and conservation strategies of the historical built heritage, monuments and artistic artifacts, due to its capability of generating deformation time series spanning time interval of more than 15 years. The presented results, achieved by applying the full resolution SBAS approach to an ERS/ENVISAT dataset relevant to the city of Rome, demonstrate the effectiveness of this technique to detect and analyze the temporal evolution of possible deformation phenomena affecting historical buildings within the investigated 1992-2009 time period.

    Fifty-nine children were enrolled in the Outpatient Health Care Package (OHCP) from 01/06/2008 to 31/03/2010. All children, except two, attended entirely the follow-up appointments; a satisfactory result, considering also that 30% of family were living outside the urban area and more than a third of the families was originated in a foreign country. At 3 months corrected age(CA) Haemoglobin mean values of 47 infants, all in iron treatment, were: 12.26 (10.1-14-1) g/dL; 25% had values between 10.1 and 12 g/dL. Mean values for Calcium were 10.75 (9.50-15.26) mg/dL Mean values for ALP were 393 (179-1075) UI/L, values >1000 UI/L were found in two infants who suspended Vitamin D treatment. At 3 months CA 50 infants performed ABR, 12 of these showing abnormalities. To date 9 infants repeated ABR at 6-9 months CA, 4 of these showed again abnormal results. Overall were found 4 ABR abnormalities among 47 children (8.5%). Outcome of 23 children at 12 months CA: no moderate or severe neurologic abnormalities were found, 4 children (17.4%) presented mild abnormalities, 2 were referred for rehabilitation. No QSM <80% was found (mean QSM 93.7%) in 10 children evaluated. One child presented growth retardation <5 degrees; 2 underwent laser treatment for ROP with normal vision, 7 (30.4%)had sistolic BP > or = 95 degrees; 6 (26%) were rehospitalized. This experience was positive: OHCP promoted a better compliance and standardization of follow-up. It would be desirable to prolong OHCP until school-age, including renal and cardiac functions monitoring.

    The great meridian line in the Basilica of Santa Maria degli Angeli in Rome was built in 1701/1702 with the scope to measure the Obliquity of the Earth's orbit in the following eight centuries, upon the will of pope Clement XI. During the winter solstice of 1701 the first measurements of the obliquity have been realized by Francesco Bianchini, the astronomer who designed the meridian line, upgrading the similar instrument realized by Giandomenico Cassini in San Petronio, Bononia. In this paper the accuracy of the data observed by Francesco Bianchini is discussed and compared with up-to-date ephemerides. The modern situation of this historical instrument is also presented.

    Objective To estimate the incidence of falsely elevated risk of ovarian malignancy algorithm (ROMA) in a group of women with pathologically confirmed endometrioma and to investigate the associated factors. Methods One hundred premenopausal women surgically diagnosed with ovarian endometrioma were selected. Preoperative clinical, laboratory, and surgical characteristics were compared between the elevated-risk group (ROMA-premenopausal value, ≥7.4%) and normal-risk group (ROMA-premenopausal value, <7.4%). Results Elevated ROMA was observed in 15 women (false positive rate, 15%). Excluding one woman with known chronic renal failure, we compared the characteristics of 99 women between the elevated-risk group (n=14) and the normalrisk group (n=85). None of the clinical and surgical variables distinguished the two groups. Serum level of CA 125 >82.3 U/mL and serum level of human epididymis protein 4 (HE4) >46 pmol/L could predict an elevated ROMA test with a statistical significance. When serum level of HE4 ≤46 pmol/L, none of the women showed an elevated ROMA test, regardless of serum level of CA 125; however, 55.6% of the women showed an elevated ROMA test when serum level of HE4 >46 pmol/L and CA 125 ≤82.3 U/mL and all women showed an elevated ROMA test when serum level of HE4 >46 pmol/L and CA 125 >82.3 U/mL. Conclusion The incidence of falsely elevated ROMA was 15% in the group of women with pathologically confirmed endometrioma. Interpretation of the ROMA results should be cautious when serum level of HE4 >46 pmol/L and CA 125 >82.3 U/mL in women with suspicious ovarian endometrioma. PMID:27462596

    We try to find out the best weight values of CA125 and HE4 in a discriminant formula classifying ovarian cancer patients from benign patients. We utilize a logistic regression analysis for the early screening system of the ovarian cancer for Korean patients. We compare our system with ROMA (Risk of Ovarian Malignancy Algorithm) of Abbot corp. In view of AUC (Area under the ROC curve), sensitivity with 95% of specificity and accuracy are considered. We performed experiments based on the logistic regression analysis separated by the case of pre- and post- menopausal stages and by the stages of progression of cancer. In our experiments, we can increase about 15.6% points of sensitivity with 95% of specificity, compared to that of ROMA. In premenopausal cases, ROMA shows 93.32% of AUC value and our system shows 97.48% of AUC, 4.1% points higher than ROMA. AUC of the ROMA for premenopausal women was 93.32%, whereas the AUC of our system was 97.48%. Furthermore, the AUC of the ROMA for early-staged ovarian cancer was 91.35%, whereas the AUC of our system was 97.22%, showing that the diagnostic performance of our system was superior over that of the ROMA in Korean patient cases.

    2006-01-01

    Roma (Gypsy ethnic) form a genetically isolated ethnical group of the identical origin with the world population of 10 to 14 millions derived from a limited number of so-called founders. Majority (about 8 millions) of Roma ethnic live in Europe, namely at Balkan and in the southwest of Europe. Roma have specific hereditary diseases, namely those caused by recessive genetic mutations. The molecular-genetic mechanism has been recently elucidated and confirmed in several diseases of the Roma population. Owing to the significant proportion of Roma in the population, patients with those diseases are possible to meet also in the Czech Republic. However, the diagnostics of those diseases is frequently difficult and they are often under diagnosed or misdiagnosed. The article gives examples of autosomal recessive diseases, which can be confirmed at the DNA level which occur in Roma population of the Czech Republic: syndrome of congenital cataract, facial dysmorphism and demyelinating neuropathy, non-syndromic prelingual deafness with GJB2 gene impairment and the congenital myastenic syndrome.

    2013-12-01

    Cancer Antigen 125 (CA125) and Human Epididymis Protein 4 (HE4) are the most studied ovarian tumor markers. Their diagnostic performance for identification of ovarian cancer are superior to CA19-9, CA72-4, and carcinoembryonic antigen, which are no more recommended for the diagnosis of presumed benign ovarian tumor. HE4 (>140 pmol/L) is superior to CA125 (>30 U/mL) in terms of specificity and positive likelihood ratio. CA125 and HE4 can be combined into an algorithm ROMA, or associated to clinical information (composite index), biological data (OVA1) or imaging (Risk for Malignancy Index (RMI), LR2). ROMA algorithm is an exponential equation combining plasmatic concentrations of HE4 and CA125. ROMA is more sensitive and less specific than HE4 in predicting epithelial ovarian cancer. ROMA is more accurate in post-menopausal women. The performance of ROMA is lower than the ultrasound model LR2 in differentiating malignant from benign ovarian tumors, whatever the hormonal status. The composite index combining CA125 with a symptoms index (pain, abdominal distension, bloating, difficulty eating) has a good sensitivity in a screening program, but because of a 12% false positive rate, ultrasound is required before management. The RMI algorithm is based on serum CA125, ultrasound findings (septation, solid zones, metastases, ascite, bilaterality) and menopausal status. RMI is less sensitive, but more specific than ROMA or OVA1 for the classification of ovarian masses. The addition of HE4 to RMI seems to be the most accurate. The subjective evaluation of ovarian cysts by sonography and color Doppler is better than ROMA and RMI algorithms, and not affected by the hormonal status.

  19. Rank-ordered multifractal analysis for intermittent fluctuations with global crossover behavior

    The rank-ordered multifractal analysis (ROMA), a recently developed technique that combines the ideas of parametric rank ordering and one-parameter scaling of monofractals, has the capabilities of deciphering the multifractal characteristics of intermittent fluctuations. The method allows one to understand the multifractal properties through rank-ordered scaling or nonscaling parametric variables. The idea of the ROMA technique is applied to analyze the multifractal characteristics of the auroral zone electric-field fluctuations observed by the SIERRA sounding rocket. The observed fluctuations span across contiguous multiple regimes of scales with different multifractal characteristics. We extend the ROMA technique such that it can take into account the crossover behavior - with the possibility of collapsing probability distribution functions - over these contiguous regimes.

  20. Rank-Ordered Multifractal Analysis of Probability Distributions in Fluid Turbulence

    2015-11-01

    Rank-Ordered Multifractal Analysis (ROMA) was introduced by Chang and Wu (2008) to describe the multifractal characteristic of intermittent events. The procedure provides a natural connection between the rank-ordered spectrum and the idea of one-parameter scaling for monofractals. This technique has successfully been applied to MHD turbulence simulations and turbulence data observed in various space plasmas. In this paper, the technique is applied to the probability distributions in the inertial range of the turbulent fluid flow, as given in the vast Johns Hopkins University (JHU) turbulence database. In addition, a refined method of finding the continuous ROMA spectrum and the scaled probability distribution function (PDF) simultaneously is introduced.

  1. A grassmannian formulation of the WZW and minimal models

    1989-05-01

    Grassmannians provide a geometrical interpretation of infinite dimensional Kac-Moody and Virasoro algebras. Here we show how to obtain, using this formulism, the values of the central charges and the conformal dimensions (weights) corresponding to the WZW and minimal models. This is achieved by suitably generalizing the procedure which gave the central charge and the conformal dimension of the b-c system. In analogy with this previous case we get a prescription to compute the correlation functions of such models on Riemann surfaces of arbitrary genus.

    We present an analysis of the optical spectra available in the Sloan Digital Sky Survey data release nine (SDSS DR9) for the blazars listed in the ROMA-BZCAT and for the γ-ray blazar candidates selected according to their IR colors. First, we adopt a statistical approach based on Monte Carlo simulations to find the optical counterparts of the blazars listed in the ROMA-BZCAT catalog. Then, we crossmatched the SDSS spectroscopic catalog with our selected samples of blazars and γ-ray blazar candidates, searching for those with optical spectra available to classify our blazar-like sources and, whenever possible, to confirm their redshifts. Our main objectives are to determine the classification of uncertain blazars listed in the ROMA-BZCAT and to discover new gamma-ray blazars. For the ROMA-BZCAT sources, we investigated a sample of 84 blazars, confirming the classification for 20 of them and obtaining 18 new redshift estimates. For the γ-ray blazars, indicated as potential counterparts of unassociated Fermi sources or with uncertain nature, we established the blazar-like nature of 8 out of the 27 sources analyzed and confirmed 14 classifications.

    Seventy-one cultivars of sweet sorghum (Sorghum bicolor L.) were screened for aluminium (Al) tolerance by measuring relative root growth (RRG). Two contrasting cultivars, ROMA (Al tolerant) and POTCHETSTRM (Al sensitive), were selected to study shorter term responses to Al stress. POTCHETSTRM had higher callose synthase activity, lower β-1,3-glucanase activity and more callose deposition in the root apices during Al treatment compared with ROMA. We monitored the expression of 12 genes involved in callose synthesis and degradation and found that one of these, SbGlu1 (Sb03g045630.1), which encodes a β-1,3-glucanase enzyme, best explained the contrasting deposition of callose in ROMA and POTCHETSTRM during Al treatment. Full-length cDNAs of SbGlu1 was prepared from ROMA and POTCHETSTRM and expressed in Arabidopsis thaliana using the constitutive cauliflower mosaic virus (CaMV) 35S promoter. Independent transgenic lines displayed significantly greater Al tolerance than wild-type plants and vector-only controls. This phenotype was associated with greater total β-1,3-glucanase activity, less Al accumulation and reduced callose deposition in the roots. These results suggest that callose production is not just an early indicator of Al stress in plants but likely to be part of the toxicity pathway that leads to the inhibition of root growth.

    Aims: We present an extension of the ROMA map-making algorithm for the generation of optimal cosmic microwave background polarization maps. The new code allows for a possible cross-correlated noise component among the detectors of a CMB experiment. A promising application is the forthcoming LSPE balloon-borne experiment, which is devoted to the accurate observation of CMB polarization at large angular scales. Methods: We generalized the noise covariance matrix in time domain to account for all the off-diagonal terms due to the detector cross-talk. Hence, we performed preliminary forecasts of the LSPE-SWIPE instrument. Results: We found that considering the noise cross-correlation among the detectors results in a more realistic estimate of the angular power spectra. In particular, the extended ROMA algorithm has provided a considerable reduction of the spectra error bars. We expect that this improvement could be crucial in constraining the B-mode polarization at the largest scales.

    The μ-opioid receptor is the primary site of action of most opioids. The 118A>G (rs1799971) polymorphism in exon 1 of the μ-opioid receptor gene (OPRM1) leads to an Asn40Asp amino acid change that affects a putative N-glycosylation site. It has been widely investigated for association with alcohol and drug dependence and pain sensitivity, with mixed results. The aim of the current study was to examine whether this polymorphism was associated with heroin dependence in a large Bulgarian cohort of 1842 active users and 1451 population controls. SNP genotyping was done using Real-Time PCR TaqMan technology. Association analyses were conducted, separately for Roma and non-Roma participants. Our results suggest that there is no direct effect of 118A>G genotype on the risk for heroin dependence among active heroin users.

    We investigated ethnic/religious mortality differentials in Bulgaria during the 1990s. The analyses employed a unique longitudinal data set covering the entire population of Bulgaria from the census of 1992 until 1998. The mortality of Roma is very high compared to all other ethnic/religious groups. The excess applies to nearly every cause of death examined and is not entirely explained by the adverse location of Roma on social and economic variables. For young men, Muslim mortality is substantially lower than that of non-Muslims when socioeconomic differences are controlled. An analysis of causes of death suggests that lower consumption of alcohol may contribute to this ‘Muslim paradox’. For older Muslim women, a significant mortality disadvantage remains after controls are imposed. Suicide mortality is lower for Muslims than for Christian groups of the same ethnicity. Consistent with deteriorating economic conditions over the study period, mortality was rising, particularly for women. PMID:21294054

    This study examines the relationships between nationalism and integration attitudes on one hand, and anti-Roma prejudice on the other. Using Stephan and Stephan's threat theory, the study analyzes whether and to what extent these relationships are mediated by perceived economic and symbolic threats. Data were collected among 16- and 17-year-old students in Serbia and The Netherlands. A path analysis shows that perceived economic and symbolic threats mediate the relationships between nationalism and integration on one hand, and Romaphobia on the other. Moreover, the findings show that these relationships are comparable between Serbian and Dutch youth. Levels of threat and Romaphobia differ between countries. Youth in the Netherlands, who barely have contact opportunities with Roma, are characterized by higher threat and Romaphobia scores than Serbian youth, who have proportionally more contact opportunities. Explanations are discussed as well as implications for theory and prejudice reduction in diverse intercultural settings. PMID:22519428

    Hereditary motor and sensory neuropathy type Russe (HMSNR), also called CMT4G, is an autosomal recessive inherited peripheral neuropathy (IPN) caused by a founder mutation in the HK1 gene. HMSNR affects only patients with Roma origin, similar to the better known HMSN type Lom clarified earlier. By testing IPN patients with Roma origin, we realized that HMSNR affects surprisingly many patients in the Czech Republic. HMSNR is one of the most frequent types of IPN in this country and appears to be twice more frequent than HMSNL. Pronounced lower limb atrophies and severe deformities often lead to walking inability in even young patients, but hands are usually only mildly affected even after many years of disease duration. The group of 20 patients with HMSNR presented here is the first report about the prevalence of HMSNR from central Europe. PMID:26822750

    Greece is the only European Union member state that in 2008 included hepatitis A (HAV) vaccine in the routine national childhood immunization program (NCIP). Given that the resources allocated to public health have dramatically decreased since 2008 and that Greece is a low endemicity country for the disease, the benefit from universal vaccination has been questioned. The aim of this paper is to summarize the available epidemiological data of the disease for 1982-2013, and discuss the effects of universal vaccination on disease morbidity. Descriptive analysis, ARIMA modeling and time series intervention analysis were conducted using surveillance data of acute HAV. A decreasing trend of HAV notification rate over the years was identified (p<0.001). However, universal vaccination (~ 80% vaccine coverage of children) had no significant effect on the annual number of reported cases (p = 0.261) and has resulted to a progressive increase of the average age of infection in the general population. The mean age of cases before the inclusion of the vaccine to NCIP (24.1 years, SD = 1.5) was significantly lower than the mean age of cases after 2008 (31.7 years, SD = 2.1) (p<0.001). In the last decade, one third of all reported cases were Roma (a population accounting for 1.5% of the country's total population) and in 2013 three outbreaks with 16, 9 and 25 Roma cases respectively, were recorded, indicating the decreased effectiveness of the current immunization strategy in this group. Data suggest that universal vaccination may need to be re-considered. Probably a more cost effective approach would be to implement a program that will include: a) vaccination of high risk groups, b) universal vaccination of Roma children and improving conditions at Roma camps, c) education of the population and travel advice, and d) enhancement of the control measures to increase safety of shellfish and other foods.

    Hepatitis A vaccine was introduced in the Greek National Immunization Program in 2008. To estimate possible impact of the universal vaccination implementation, time trends of hospitalizations for hepatitis A at the Infectious Diseases Unit of a Tertiary Pediatric Hospital in Athens during 1999-2013 were analyzed. Hepatitis A hospitalizations were recorded from the discharge database and were expressed as frequencies and rate of annual departmental hospitalizations. Time series analysis (ARIMA) was used to explore trends and the impact of the vaccination. Moreover, changes in patient age, population group distribution and the duration of hospitalization were also examined. Hepatitis A hospitalizations rate significantly decreased between pre-vaccination (1999-2008) and post-vaccination (2009-2013) era from 50.5 to 20.8/1000 hospitalizations (p = 0.005). A 3-year periodicity and a trend of reduction on hepatitis A hospitalizations rates across years were noted. Roma children had significant higher rates of hepatitis A hospitalization, followed by immigrant children. Importantly, possibly due to preceding vaccine availability with considerable uptake in private market and unvaccinated group/pockets of children (Roma), overall vaccination effect was less apparent when compared to data from other countries that implemented universal vaccination. No significant change in patient age, population group distribution, or duration of hospitalization was observed. High risk groups such as Roma children should be targeted for vaccination to reduce future outbreaks. PMID:27141813

    The Irish Travellers are an itinerant group in Ireland that has been socially isolated. Two hypotheses have been proposed concerning the genetic origin of the Travellers: (1) they are genetically related to Roma populations in Europe that share a nomadic lifestyle or (2) they are of Irish origin, and genetic differences from the rest of Ireland reflect genetic drift. These hypotheses were tested using data on 33 alleles from 12 red blood cell polymorphism loci. Comparison with other European, Roma, and Indian populations shows that the Travellers are genetically distinct from the Roma and Indian populations and most genetically similar to Ireland, in agreement with earlier genetic analyses of the Travellers. However, the Travellers are still genetically distinct from other Irish populations, which could reflect some external gene flow and/or the action of genetic drift in a small group that was descended from a small number of founders. In order to test the drift hypothesis, we analyzed genetic distances comparing the Travellers to four geographic regions in Ireland. These distances were then compared with adjusted distances that account for differential genetic drift using a method developed by Relethford (Hum Biol 68 (1996) 29-44). The unadjusted distances show the genetic distinctiveness of the Travellers. After adjustment for the expected effects of genetic drift, the Travellers are equidistant from the other Irish samples, showing their Irish origins and population history. The observed genetic differences are thus a reflection of genetic drift, and there is no evidence of any external gene flow. PMID:23180293

    There is an increasing interest on developing virtual enterprises in order to deal with the globalisation of the economy, the rapid growth of information technologies and the increase of competitiveness. In this paper we deal with the development of normative open virtual enterprises (NOVEs). They are systems with a global objective that are composed of a set of heterogeneous entities and enterprises that exchange services following a specific normative context. In order to analyse and design systems of this kind the multi-agent paradigm seems suitable because it offers a specific solution for supporting the social and contractual relationships between enterprises and for formalising their business processes. This paper presents how the Regulated Open Multi-agent systems (ROMAS) methodology, an agent-oriented software methodology, can be used to analyse and design NOVEs. ROMAS offers a complete development process that allows identifying and formalising of the structure of NOVEs, their normative context and the interactions among their members. The use of ROMAS is exemplified by means of a case study that represents an automotive supply chain.

    Consumption of raw round and Roma tomatoes has been associated with outbreaks of salmonellosis. A study was done to determine whether survival and growth of Salmonella in and on tomatoes is affected by variety of tomato, stage of ripeness, and storage temperature. The influence of acid adaptation of cells and site of inoculation on survival and growth was studied. Salmonella grew in stem scar and pulp tissues of round, Roma, and grape tomatoes stored at 12 and 21 degrees C but not in those tomatoes stored at 4 degrees C. Survival and growth was largely unaffected by variety and stage of ripeness at the time of inoculation. The pathogen did not grow on the skin of grape tomatoes stored at 4, 12, and 21 degrees C. Survival and growth of Salmonella inoculated into stem scar and pulp tissues of round and Roma tomatoes were unaffected by exposure of cells to an acidic (pH 4.75) environment before inoculation. Results emphasize the importance of preventing contamination of tomatoes with Salmonella at all stages of ripeness, regardless of variety or previous exposure of cells to an acidic environment.

    YRM logo The Young Researcher Meeting (www.yrmr.it) has been a rapidly growing event for the last few years. Together with other initiatives which have emerged in several research areas, the young researcher meeting marks the awareness and the desire of PhD students, postdoctoral fellows and young researchers to play a major role in scientific progress. Devoted to the discussion and the interchange of new developments and ideas in physics, the meeting is primarily aimed at graduate students and postdoctoral researchers, who are encouraged to present their work in an informal atmosphere. One of the main purposes of the conference is to create an international network of young researchers, both experimentalists and theorists, and fruitful collaborations across the different branches of physics. Born in Rome in 2009, after three editions that strengthened it, the Young Researcher Meeting 2013 was held in Trieste. Propelled by the past success, the fourth meeting was a two-day conference on 3-4June. It was sponsored by the International School for Advanced Studies - SISSA - and the University of Padova, thus acquiring an even further international drive. In this volume, we collect some of the contributions that were presented at the conference. They cover topics in astrophysics and cosmology, particle and theoretical physics, soft and condensed matter, biophysics and medical physics.

    Linguistic and genetic studies on Roma populations inhabited in Europe have unequivocally traced these populations to the Indian subcontinent. However, the exact parental population group and time of the out-of-India dispersal have remained disputed. In the absence of archaeological records and with only scanty historical documentation of the Roma, comparative linguistic studies were the first to identify their Indian origin. Recently, molecular studies on the basis of disease-causing mutations and haploid DNA markers (i.e. mtDNA and Y-chromosome) supported the linguistic view. The presence of Indian-specific Y-chromosome haplogroup H1a1a-M82 and mtDNA haplogroups M5a1, M18 and M35b among Roma has corroborated that their South Asian origins and later admixture with Near Eastern and European populations. However, previous studies have left unanswered questions about the exact parental population groups in South Asia. Here we present a detailed phylogeographical study of Y-chromosomal haplogroup H1a1a-M82 in a data set of more than 10,000 global samples to discern a more precise ancestral source of European Romani populations. The phylogeographical patterns and diversity estimates indicate an early origin of this haplogroup in the Indian subcontinent and its further expansion to other regions. Tellingly, the short tandem repeat (STR) based network of H1a1a-M82 lineages displayed the closest connection of Romani haplotypes with the traditional scheduled caste and scheduled tribe population groups of northwestern India.

    Upon the invasion of the host by microorganisms, innate immunity is triggered through pathogen recognition by pattern recognition receptors (PRRs). Toll-like receptors (TLRs) are the best-studied class of PRRs, and they recognize specific pathogen-associated molecular patterns (PAMPs) from various microorganisms. A large number of studies have shown that genetic variation in TLRs may influence susceptibility to infections. We assessed the genetic variation of TLR2, which encodes one of the most important TLRs, in various populations around the globe and correlated it with changes in the function of the molecule. The three best-known nonsynonymous TLR2 polymorphisms (1892C>A, 2029C>T, and 2258G>A) were assessed in different populations from the main continental masses: Romanians, Vlax-Roma, Dutch (European populations), Han Chinese (East Asia), Dogon, Fulani (Africa), and Trio Indians (America). The 2029C>T polymorphism was absent in both European and non-European populations, with the exception of the Vlax-Roma, suggesting that this polymorphism most likely arose in Indo-Aryan people after migration into South Asia. The 1892C>A polymorphism that was found exclusively in European populations, but not in Asian, African, or American volunteers, probably occurred in proto-Indo-Europeans. Interestingly, 2258G>A was present only in Europeans, including Vlax-Roma, but at a very low frequency. The differential pattern of the TLR2 polymorphisms in various populations may explain some of the differences in susceptibility to infections between these populations.

    Dual hereditary jaundice, a combination of Dubin-Johnson and Gilbert's syndromes, is a rare clinical entity resulting from the compound defects of bilirubin conjugation and transport. We aimed to study the hereditary jaundice in 56 members from seven seemingly unrelated Roma families, to find the causal genetic defect and to estimate its origin in Roma population. On the basis of biochemical results of total and conjugated serum bilirubin and clinical observations, ABCC2 gene, TATA box and phenobarbital enhancer (PBREM) of UGT1A1 gene were analyzed by sequencing, RFLP and fragment analysis. We found a novel variant c.1013_1014delTG in the eighth exon of ABCC2 gene in 17 individuals in homozygous state. Dual defect NG_011798.1:c.[1013_1014delTG]; NG_002601.2:g.[175492_175493insTA] in homozygous state was found in four subjects. Biochemical analyses of porphyrins and coproporphyrin isomers in urine performed by HPLC showed inverted ratio of excreted coproporphyrin, with the predominance of coproporphyrin I (up to 100%), typical for patients with Dubin-Johnson syndrome. Pursuant cultural and social specifics of the population led us to suspect a founder effect; therefore, we performed a haplotype study using genotyping data from Affymetrix Genome-Wide Human SNP Array 6.0. As a result, we detected a common 86 kbp haplotype encompassing promoter and part of the ABCC2 coding region among all families, and estimated the age of the ancestral variant to 178-185 years. In this study, we found a novel deletion in ABCC2 gene, described genetic and biochemical features of dual hereditary jaundice and confirmed the existence of founder effect and common haplotype among seven Roma families.

  15. The influence of the C+N+O abundances on the determination of the relative ages of globular clusters: the case of NGC1851 and NGC6121 (M4)†

    The colour-magnitude diagram (CMD) of NGC1851 presents two subgiant branches (SGBs), probably due to the presence of two populations differing in total C+N+O (carbon+nitrogen+oxygen) content. We test the idea that a difference in total C+N+O may simulate an age difference when comparing the CMD of clusters to derive relative ages. We compare NGC1851 with NGC6121 (M4), a cluster of very similar [Fe/H]. We find that, with a suitable shift of the CMDs that brings the two red horizontal branches at the same magnitude level, the unevolved main sequence and red giant branch match, but the SGB of NGC6121 and its red giant branch `bump' are fainter than in NGC1851. In particular, the SGB of NGC6121 is even slightly fainter than the faint SGB in NGC1851. Both these features can be explained if the total C+N+O in NGC6121 is larger than that in NGC1851, even if the two clusters are coeval. We conclude by warning that different initial C+N+O abundances between two clusters, otherwise similar in metallicity and age, may lead to differences in the turnoff morphology that can be easily attributed to an age difference.

    Ozone-induced stress-ethylene emissions from the adaxial and abaxial leaf surfaces of four plant species (Glycine max (L) Merr. cv. Dare, Lycopersicon esculentum Mill cv. Roma VF, Eucalyptus globulus Labill. and Hedera helix L.) were studied to determine if the stress ethylene diffused through the stomata or cuticle. In plants not exposed to ozone, basal ethylene was detected above both the adaxial and abaxial leaf surfaces of all the plant species examined, indicating that some ethylene can diffuse across the leaf cuticle. Oxone-induced stress ethylene production in all species examined. These data indicate that ozone-induced stress ethylene primarily diffuses from the leaf via the stomata.

    Rome is an open book to human history, and traveling from the city center to the Nuova Fiera da Roma, as most of this year's attendees to EULAR had to do to reach the congress site, is a voyage from the remains of the Roman Empire throughout the middle ages and across most of human history to the modern architecture that characterizes the new exposition facilities next to the airport of Fiumicino. EULAR offers a yearly development on therapies for diseases with a clear, direct negative impact on physical functioning of the sufferers, and this report will review most of the therapeutic novelties discussed this year.

    In this issue of the Journal, Dr. Paolo Roma and colleagues review international research spanning 60 years and highlight the centrality of psychiatric factors in the phenomenon of homicide-suicide (H-S). This commentary examines several challenges presented by definitional variability and the use of general sources as data. We suggest directions for future research, particularly using the established violence literature, to move toward intervention and management of H-S. We also examine the similarities between H-S and stalking and reflect on the potential for the stalking literature to inform the understanding and management of H-S.

    This topical issue grew out of the International Conference "Noncommutative Geometry and Applications" held 16-21 June 2014 at Villa Mondragone, Frascati (Roma). The main purpose of the conference was to have a unified view of different incarnations of noncommutative geometry and its applications. The seven papers collected in the present topical issue represent a good sample of the topics covered at the workshop. The conference itself was one of the climaxes of the Franco-Italian project GREFI-GENCO, which was initiated in 2007 by CNRS and INDAM to promote and enhance collaboration and exchanges between French and Italian researchers in the area of noncommutative geometry.

    Summary This article is based on analysis of 4 couple’s personal and public documents, in order to integrate personal choices, values and ideas with cultural representations and social attitudes. Moreover, being based on Italian sources from the nineteenth century, the study offers an historical insight on the Italian nation-building process and its political and social foundations. This study is based on archival and printed primary sources from: Gianna Maffei and Ercole Trotti Mosti (Museo Centrale del Risorgimento – Roma – MCRR); Augusto Pierantoni and Grazia Mancini (Museo Centrale del Risorgimento – Roma); Luigi Majno and Ersilia Bronzini (Archivio Unione Femminile Nazionale – Milano); Angiolo Orvieto and Laura Cantoni (Archivio Contemporaneo Bonsanti del Gabinetto Vieuesseux – Firenze – ACGV). This study reflects on love as a political and moral issue, by linking the personal sphere of subjectivity to the public dimension of the political community. An extensive understanding of the role played by the perception and the expression of sentiments can be considered as the central issue of this analysis. PMID:22037756

    We analyze magnetic field data from Venus Express (VEX) and CLUSTER to investigate the turbulent properties of the solar wind and the Earth's and Venus' magnetosheaths. A systematic study of the PDFs (Probability Distribution Functions) of the measured magnetic fluctuations and their fourth order moments (kurtosis) reveals numerous intermittent time series. The presence of intermittency is marked by non-Gaussian PDFs with heavy wings and a scale dependent kurtosis. Higher order analyses on the scale dependence of several moment orders of the PDFs, the structure functions, along with the scaling of the kurtosis allow for a selection of scales that pertain to different scaling regimes, governed by different physics. On such sub-ranges of scales we investigate the fractal structure of fluctuations through the Rank Ordered Multifractal Analysis - ROMA (Chang and Wu, 2008). ROMA is applied to a selection of intermittent magnetic field time series in the solar wind and planetary magnetosheaths and helps to quantify the turbulence properties through the estimation of a spectrum of local Hurst exponents.

    Measles re-emerged in a nationwide outbreak in Bulgaria from 2009 to 2011 despite reported high vaccination coverage at national level. This followed an eight-year period since the last indigenous cases of measles were detected. The Bulgarian National Centre of Infectious and Parasitic Diseases collated measles surveillance data for 2009-2011. We analysed data for age group, sex, ethnicity, diagnosis confirmation, vaccination, hospitalisation, disease complications, and death and describe the outbreak control measures taken. The outbreak started in April 2009 following an importation of measles virus and affected 24,364 persons, predominantly Roma. Most cases (73%) were among children < 15 years old. Vaccination status was available for 52% (n = 12,630) of cases. Of children 1-14 years old, 22% (n = 1,769) were unvaccinated and 70% (n = 5,518) had received one dose of a measles-containing vaccine. Twenty-four measles-related deaths were reported. The Roma ethnic group was particularly susceptible to measles. The magnitude of the outbreak resulted primarily from the accumulation of susceptible children over time. This outbreak serves as a reminder that both high vaccination coverage and closing of immunity gaps across all sections of the population are crucial to reach the goal of measles elimination.

    Pathogenic mutations of MARVELD2, encoding tricellulin, a tricelluar tight junction protein, cause autosomal recessive non-syndromic hearing loss (DFNB49) in families of Pakistan and Czech Roma origin. In fact, they are a significant cause of prelingual hearing loss in the Czech Roma, second only to GJB2 variants. Previously, we reported that mice homozygous for p.Arg497* variant of Marveld2 had a broad phenotypic spectrum, where defects were observed in the inner ear, heart, mandibular salivary gland, thyroid gland and olfactory epithelium. The current study describes the types and frequencies of MARVELD2 alleles and clinically reexamines members of DFNB49 families. We found that MARVELD2 variants are responsible for about 1.5% (95% CI: 0.8 – 2.6) of non-syndromic hearing loss in our cohort of 800 Pakistani families. The c.1331+2T>C allele is recurrent. In addition, we identified a novel large deletion in a single family, which appears to have resulted from non-allelic homologous recombination between two similar Alu short interspersed elements. Finally, we observed no other clinical manifestations co-segregating with hearing loss in DFNB49 human families, and hypothesize that the additional abnormalities in the Marveld2 mutant mouse indicates a critical non-redundant function for tricellulin in other organ systems.

    Direct numerical simulations of thermal convection are conducted for a cylindrical cell of aspect ratio .5ex1-.1em/ -.15em.25ex2 . The Prandtl number (Pr) varies from 10^0 to 10^4 and the Rayleigh numbers (Ra) are moderate (10^5 < Ra < 10^9). This study is motivated by the fact that the role of the Prandtl number in convective heat transport is not yet fully understood. The three-dimensional behaviors of the temperature and velocity fields, of the viscous and thermal dissipation fields, and of the diffusive and convective heat fluxes are explored. In the ranges of Pr and Ra considered, we find steady, periodic and chaotic regimes, and large-scale structures which are more complex than the single recirculation cell filling the whole volume. Multiple flow structures are found to be associated with a given set of conditions. The multiple solutions seem to be more probable at higher Pr numbers and could explain the scatter in some data trends.

    Objective To explore female and transvestite sex workers’ perceptions of risk in the sex work environment in Serbia. Design Qualitative interview study. Setting Street based locations for sex work in Belgrade and Pancevo, Serbia. Participants 31 female and transvestite sex workers. Results Violence, including police violence, was reported as a primary concern in relation to risk. Violence was linked to unprotected sex and the reduced capacity for avoiding sexual risk. Participants reported that coerced sex was routinely provided to the police in exchange for freedom from detainment, arrest, or fine, and was enforced by the perceived threat of violence, sometimes realised. Accounts contained multiple instances of physical and sexual assault, presented as abuses of police authority, and described policing as a form of moral punishment. This was largely through non-physical means but was also enforced through physical violence, especially towards transvestite and Roma sex workers, whose experience of police violence was reported as relentless and brutal and connected with broader social forces of discrimination in this setting, especially towards Roma. Conclusion Preventing violence towards sex workers, which can link with vulnerability to sexually transmitted infections, is a priority in Serbia. This requires monitoring perpetrators of violence, providing legal support to sex workers, and creating safer environments for sex work. PMID:18667468

    OBJECTIVE: To characterize the circumstances in which poliomyelitis occurred among three children in Bulgaria during 2001 and to describe the public health response. METHODS: Bulgarian authorities investigated the three cases of polio and their contacts, conducted faecal and serological screening of children from high-risk groups, implemented enhanced surveillance for acute flaccid paralysis, and conducted supplemental immunization activities. FINDINGS: The three cases of polio studied had not been vaccinated and lived in socioeconomically deprived areas of two cities. Four Roma children from the Bourgas district had antibody titres to serotype 1 poliovirus only, and wild type 1 virus was isolated from the faeces of two asymptomatic Roma children in the Bourgas and Sofia districts. Poliovirus isolates were related genetically and represented a single evolutionary lineage; genomic sequences were less than 90% identical to poliovirus strains isolated previously in Europe, but 98.3% similar to a strain isolated in India in 2000. No cases or wild virus isolates were found after supplemental immunization activities were launched in May 2001. CONCLUSIONS: In Bulgaria, an imported poliovirus was able to circulate for two to five months among minority populations. Surveillance data strongly suggest that wild poliovirus circulation ceased shortly after supplemental immunization activities with oral poliovirus vaccine were conducted. PMID:12973639

    BACKGROUND Gypsies, Travellers and Roma (referred to as Travellers) are less likely to access health services, including immunisation. To improve immunisation rates, we need to understand what helps and hinders individuals in these communities in taking up immunisations. AIMS (1) Investigate the barriers to and facilitators of acceptability and uptake of immunisations among six Traveller communities across four UK cities; and (2) identify possible interventions to increase uptake of immunisations in these Traveller communities that could be tested in a subsequent feasibility study. METHODS Three-phase qualitative study underpinned by the social ecological model. Phase 1: interviews with 174 Travellers from six communities: Romanian Roma (Bristol); English Gypsy/Irish Traveller (Bristol); English Gypsy (York); Romanian/Slovakian Roma (Glasgow); Scottish Showpeople (Glasgow); and Irish Traveller (London). Focus on childhood and adult vaccines. Phase 2: interviews with 39 service providers. Data were analysed using the framework approach. Interventions were identified using a modified intervention mapping approach. Phase 3: 51 Travellers and 25 service providers attended workshops and produced a prioritised list of potentially acceptable and feasible interventions. RESULTS There were many common accounts of barriers and facilitators across communities, particularly across the English-speaking communities. Scottish Showpeople were the most similar to the general population. Roma communities experienced additional barriers of language and being in a new country. Men, women and service providers described similar barriers and facilitators. There was widespread acceptance of childhood and adult immunisation, with current parents perceived as more positive than their elders. A minority of English-speaking Travellers worried about multiple/combined childhood vaccines, adult flu and whooping cough. Cultural concerns about vaccines offered during pregnancy and about human

    The Italian Group for Bone Marrow Transplantation (Gruppo Italiano Trapianto di Midollo Osseo, GITMO) recently formalized criteria for a shared definition of poor mobilizer in order to facilitate randomized clinical trials and study comparison focusing on the efficacy of current mobilizing regimens. The availability of a standardized tool for poor mobilizer definition suggested us to retrospectively test GITMO criteria feasibility and applicability. Therefore we analyzed medical and laboratory records of adult patients affected by myeloma (MM) or lymphoma undergoing mobilization for autologous peripheral blood HSC collection from January 2010 to June 2011, at Servizio di Emotrasfusione, Istituto di Ematologia, Università Cattolica Del Sacro Cuore, Roma, UOC SIMT AO S. Camillo Forlanini Roma and SIMT Fondazione Policlinico Tor Vergata Roma. We collected data about 227 patients (134 male, 93 female) affected by MM (31.3%) NHL (58.6%) e HD (10.1%). Thirty-nine patients, 21 male and 18 female met proven poor mobilizer criteria definition resulting in a incidence of 17.2% (12.7% in MM, 21.8% in NHL and 4.3% in HD). Eleven patients, seven affected by lymphoma and four affected by myeloma, were defined predicted PM according to major criteria. Eight patients, seven affected by lymphoma and one affected by myeloma, were define predicted PM according to minor criteria. Sixteen out of 39 patients defined as poor mobilizer either according to major or minor criteria underwent collection procedures and eight (20.5%) achieved a cell dose ⩾2×10(6)/kg CD34(+) cells. GITMO criteria application was easy and resulted in poor mobilizer incidence comparable to current literature. Definitions of proven poor mobilizer and predicted poor mobilizer according to major criteria were very effective while minor criteria were less predictive. These results came from a retrospective analysis and therefore should be validated in future prospective trial. On the other hand these data could be

    2015-09-01

    Studying pulsars from ground-based telescopes needs data analysis to be performed according to specific requirements. Because of the periodic behavior of these objects such requirements are expressed in terms of timing. In fact, several factors must be taken into account to correctly extract the period (frequency) and then light curves of pulsars. Until now, analysis software packages have been mainly developed for satellite data and are not completely suitable for optical observations from the ground. A software package called GUIDA has been developed to analyze optical photometric data recorded by the SiFAP instrument, completely conceived and realized at the Physics Department of La Sapienza-Università di Roma. This software package is capable of analyzing data relative to ground observations, including timing corrections, and of deriving corrected pulsar light curves.

    The SPARC project has entered its installation phase at the Frascati National Laboratories of INFN: its main goal, the promotion of an R&D activity oriented to the development of a high brightness photoinjector to drive SASE-FEL experiments, is being vigorously pursued by a collaboration among ENEA-INFN-CNR-Universita di Roma Tor Vergata-INFM-ST. In this paper we will report on the installation and test of some major components, like Ti:Sa laser system, RF gun and RF power system. Advancements in the control and beam diagnostics systems will also be reported, in particular on the emittance-meter device for beam emittance measurements in the drift space downstream the RF gun. Recent results on laser pulse shaping show the feasibility of producing 10 ps flat-top laser pulses in the UV with rise time below 1 ps. First FEL experiments have been proposed, using SASE, seeding and non-linear resonant harmonics.

  18. The impact of recent events on human genetic diversity.

    PubMed

    Jobling, Mark A

    2012-03-19

    The historical record tells us stories of migrations, population expansions and colonization events in the last few thousand years, but what was their demographic impact? Genetics can throw light on this issue, and has mostly done so through the maternally inherited mitochondrial DNA (mtDNA) and the male-specific Y chromosome. However, there are a number of problems, including marker ascertainment bias, possible influences of natural selection, and the obscuring layers of the palimpsest of historical and prehistorical events. Y-chromosomal lineages are particularly affected by genetic drift, which can be accentuated by recent social selection. A diversity of approaches to expansions in Europe is yielding insights into the histories of Phoenicians, Roma, Anglo-Saxons and Vikings, and new methods for producing and analysing genome-wide data hold much promise. The field would benefit from more consensus on appropriate methods, and better communication between geneticists and experts in other disciplines, such as history, archaeology and linguistics.

    2 groups of patients (1200 and 1500 respectively) were patch tested with different concentrations of perfume mix and fragrance raw materials. The study was to evaluate the incidence of contact dermatitis to fragrances in Roma, Italy, and the influence of limited variations in fragrance and perfume mix concentrations on patch test responses. The results showed that a decrease in the perfume mix concentration from 16% to 8% correlated with a decrease in the % of positive patients (from 5.2% to 3.6%). Variations in the concentration of fragrance raw materials did not influence the % of positive reactions in the 2 groups. The perfume mixture at 16% or 8% gave some positive results, without a corresponding reaction to any of the constituents, that were not related to an excited skin syndrome.

The purpose of the research was to study the complex and stratified site of the Arch of Titus at the Circus Maximus aiming, first of all, at completing the existing traditional graphic documentation using cataloguing and survey innovative methodologies, and, secondly, at supporting new proposals for the reconstruction and Anastylosis of the Arch itself. This tested methodology whose fundamental element is the three-dimensional textured model of each fragment, can also be used in other sites and contexts.

    With the exception of Guyana and Trinidad, suicide rates in the Caribbean are relatively low compared with those in other countries. Homicide rates, however, have increased over the past 15 years, especially in Jamaica and Trinidad. The link between suicide, homicide, and homicide followed by suicide (H-S) is not well established. A newspaper review of H-S events in a selection of Caribbean territories revealed a surprising number of these events. Characteristics of perpetrators were similar to those documented in the literature. The authors agree with Roma et al. that national tracking systems for H-S are needed. Empirical research on this topic in the Caribbean is also desperately needed.

    This paper deals with the creation of appropriate conditions aimed at developing social services for reuse and recycling of waste electrical and electronic equipment (WEEE), by the inclusion of handicapped and Roma people in the workforce. Application areas for the project are the Hellenic (Greek) regions of Thessaly and North Aegean, where these groups suffer from professional and social exclusion. The efforts to reduce unemployment in the two aforementioned groups, together with the efforts to implement related Greek and European legislation for sustainable WEEE management, are examined here. Furthermore, networking and cooperation at local, regional and central levels between small enterprises, entrepreneurships and local authorities are examined, so that these social enterprises and their corresponding investments may support the development of the Greek alternative WEEE recycling system.

    Soil water repellency (SWR) has been reported in New Zealand, but knowledge on its importance for the country's economy and environment is limited. Our recent survey on the occurrence of SWR under pasture across the North Island of New Zealand showed that most soils exhibited SWR when dry independent of climate but influenced by the soil order. SWR is discussed as an important soil surface condition enhancing run-off and the transfer of fertilizers and pesticides from agricultural land into waterways. So far, the impact of SWR on run-off has rarely been measured. We developed a laboratory-scale run-off measurement apparatus (ROMA) to quantify directly the impact of SWR on run-off from undisturbed soil slabs. We compared the run-off resulting from the run-on of water with that resulting from an ethanol (30% v/v) solution, which is a fully-wetting liquid even in severely hydrophobic soils. Thus, the experiments with the ethanol solution can be understood as a proxy measure of the wetting-up behaviour of hydrophilic soils. We conducted ROMA run-off experiments with air-dried soil slabs (460 mm long x 190 mm wide x 50 mm deep) collected from pastoral sites, representing three major soil orders in the North Island: Recent Soil (Fluvisol), Gley Soil (Gleysol), and Organic Soil (Histosol), with water followed by the ethanol solution at a run-on rate of 60 mm/h. Bromide was applied at 80 kg KBr/ha prior to the water experiments to assess potential solute losses via run-off. The air-dried soils had a high degree and persistence of SWR (contact angles, 97, 98 and 104° , and potential water drop penetration times, 42, 54 and 231 min for the Fluvisol, Gleysol and Histosol, respectively). Under identical soil and experimental conditions, water generated run-off from all soils, but in the experiments with the ethanol solution, the entire ethanol solution infiltrated into the soils. The ranking of the run-off coefficients of the soils directly reflected their ranking in

    Many kilometers of roads have adjacent rock slopes that are prone to rockfall. The analysis of risks associated with these types of instabilities is a complex operation requiring the precise assessment of hazard, the vulnerability and therefore the risk of vehicles on roads along the foothills. Engineering design of protection devices should aim to minimize risk while taking advantage of the most advanced technologies. Decision makers should be equipped with the technical tools permitting them to choose the best solution within the context of local maximum acceptable risk levels. The fulfilment of safety requirements for mountainside routes involves in many cases the implementation of protective measures and devices to control and manage rockfall and it is of key importance the evaluation of the positive effects of such measures in terms of risk reduction. A risk analysis management procedure for roads subject to rockfall phenomena using a specifically developed method named: Rockfall risk Management (RO.MA.) is presented and discussed. The method is based on statistic tools, using as input the data coming both from in situ survey and from historical data. It is important to highline that historical database are not often available and usually there is a lack of useful information due to a not complete setting of parameters. The analysis based only on historical data can be difficult to be developed. For this purpose a specific database collection system has been developed to provide geotechnical and geomechanical description of the studied rockside. This parameters and the data collected from historical database, define the input parameters of the Ro.Ma method. Moreover to allow the quantification of the harm, the data coming from the monitoring of the road by the road manager are required. The value of harm is proportional to the number of persons on the road (i.e. people in a vehicle) and the following traffic characteristics: type of vehicles (i.e. bicycles

  6. The impact of recent events on human genetic diversity

    The historical record tells us stories of migrations, population expansions and colonization events in the last few thousand years, but what was their demographic impact? Genetics can throw light on this issue, and has mostly done so through the maternally inherited mitochondrial DNA (mtDNA) and the male-specific Y chromosome. However, there are a number of problems, including marker ascertainment bias, possible influences of natural selection, and the obscuring layers of the palimpsest of historical and prehistorical events. Y-chromosomal lineages are particularly affected by genetic drift, which can be accentuated by recent social selection. A diversity of approaches to expansions in Europe is yielding insights into the histories of Phoenicians, Roma, Anglo-Saxons and Vikings, and new methods for producing and analysing genome-wide data hold much promise. The field would benefit from more consensus on appropriate methods, and better communication between geneticists and experts in other disciplines, such as history, archaeology and linguistics.

One can see this "porphyry" at facades of a lovely palace of Pavel I and in pedestal of the monument after Nicolas I in St Petersburg. There are many other cases of using this stone in Russia. In Paris, sarcophagus of Napoleon I Bonaparte is constructed of blocks of this stone. Really, it is Proterozoic quartzite. Geology situation, petrography and mineralogical characteristic will be reported too. Comparison with antique porphyre from the Egyptian Province of the Roma Empire is given.

    Engagement--a persistent and positive affective-motivational state of fulfillment characterized by vigor, dedication, and absorption (W. B. Schaufeli, M. Salanova, V. González-Roma, & A. B. Bakker, 2002)--has become a popular subject among academic and industry researchers. Following suggestions in the recent literature calling for further examination of the underlying factors comprising the construct of engagement, the authors investigated the factor structure of W. B. Schaufeli et al.'s measure of engagement and academic engagement's relation to academic satisfaction. Previous researchers found a 3-factor structure of engagement that comprises vigor, dedication, and absorption. The authors administered to a sample of university students a questionnaire on their level of engagement in academic work and various other measures. The results did not confirm the 3-factor structure. The present authors found engagement and satisfaction to be highly related constructs.

    In Italy the highest incidence of Tuberculosis (TB) cases is in young adult migrants. In 2011, the sanitarystaff of the Local Health Unit (ASL) Roma A promoted a vaccination campaign conducting several public health interventions in Nomad Camps. After notification of a case of TB in the Camp of Via Salaria, out of 357 Mantoux skin tests performed, 93 were positive (26%); subsequently, 5 subjects with radiographic positivity were hospitalized. The vaccination campaign was carried out to prevent the spread of infectious diseases in immigrant communities at high risk of contagion and to avoid the consequent transmission in the host country. As a result, vaccinations coverage among the residents of the Camps increased: 367 vaccinated subjects (30% more than previous year) and 612 administered vaccinations.

    The Bayash are a branch of Romanian speaking Roma living dispersedly in Central, Eastern, and Southeastern Europe. To better understand the molecular architecture and origin of the Croatian Bayash paternal gene pool, 151 Bayash Y chromosomes were analyzed for 16 SNPs and 17 STRs and compared with European Romani and non-Romani majority populations from Europe, Turkey, and South Asia. Two main layers of Bayash paternal gene pool were identified: ancestral (Indian) and recent (European). The reduced diversity and expansion signals of H1a patrilineages imply descent from closely related paternal ancestors who could have settled in the Indian subcontinent, possibly as early as between the eighth and tenth centuries AD. The recent layer of the Bayash paternal pool is dominated by a specific subset of E1b1b1a lineages that are not found in the Balkan majority populations. At least two private mutational events occurred in the Bayash during their migrations from the southern Balkans toward Romania. Additional admixture, evident in the low frequencies of typical European haplogroups, J2, R1a, I1, R1b1b2, G, and I2a, took place primarily during the early Bayash settlement in the Balkans and the Romani bondage in Romania. Our results indicate two phenomena in the Bayash and analyzed Roma: a significant preservation of ancestral H1a haplotypes as a result of considerable, but variable level of endogamy and isolation and differential distribution of less frequent, but typical European lineages due to different patterns of the early demographic history in Europe marked by differential admixture and genetic drift.

    Mitochondrial DNA sequence variation was examined by the control region sequencing (HVS I and HVS II) and RFLP analysis of haplogroup-diagnostic coding region sites in 570 individuals from four regional populations of Poles and two Russian groups from northwestern part of the country. Additionally, sequences of complete mitochondrial genomes representing K1a1b1a subclade in Polish and Polish Roma populations have been determined. Haplogroup frequency patterns revealed in Poles and Russians are similar to those characteristic of other Europeans. However, there are several features of Slavic mtDNA pools seen on the level of regional populations which are helpful in the understanding of complex interactions of the Eastern and Western Slavic populations with other European groups. One of the most important is the presence of subhaplogroups U5b1b1, D5, Z1 and U8a with simultaneous scarcity of haplogroup K in populations of northwestern Russia suggesting the participation of Finno-Ugrian tribes in the formation of mtDNA pools of Russians from this region. The results of genetic structure analyses suggest that Russians from Velikii Novgorod area (northwestern Russia) and Poles from Suwalszczyzna (northeastern Poland) differ from all remaining Polish and Russian samples. Simultaneously, northwestern Russians and northeastern Poles bear some similarities to Baltic (Latvians) and Finno-Ugrian groups (Estonians) of northeastern Europe, especially on the level of U5 haplogroup frequencies. The occurrence of K1a1b1a subcluster in Poles and Polish Roma is one of the first direct proofs of the presence of Ashkenazi-specific mtDNA lineages in non-Jewish European populations.

    The agricultural reuse of pretreated industrial wastewater resulting from cheese manufacture is shown as a suitable option for its disposal and management. This alternative presents attractive advantages from the economic and pollution control viewpoints. Pretreated cheese whey wastewater (CWW) has high contents of biodegradable organic matter, salinity and nutrients, which are essential development factors for plants with moderate to elevated salinity tolerance. Five different pretreated CWW treatments (1.75 to 10.02 dS m(-1)) have been applied in the tomato plant growth. Fresh water was used as a control run (average salinity level=1.44 dS m(-1)). Chemical characterization and indicator ratios of the leaves, stems and roots were monitored. The sodium and potassium leaf concentrations increased linearly with the salinity level in both cultivars, Roma and Rio Grande. Similar results were found in the stem sodium content. However, the toxic sodium accumulations in the cv. Roma exceeded the values obtained in the cv. Rio Grande. In this last situation, K and Ca uptake, absorption, transport and accumulation capacities were presented as tolerance mechanisms for the osmotic potential regulation of the tissues and for the ion neutralization. Consequently, Na/Ca and Na/K ratios presented lower values in the cv. Rio Grande. Na/Ca ratio increased linearly with the salinity level in leaves and stems, regardless of the cultivar. Regarding the Na/K ratio, the values demonstrated competition phenomena between the ions for the cv. Rio Grande. Despite the high chloride content of the CWW, no significant differences were observed for this nutrient in the leaves and stems. Thus, no nitrogen deficiency was demonstrated by the interaction NO3(-)/Cl(-). Nitrogen also contributes to maintain the water potential difference between the tissues and the soil. Na, P, Cl and N radicular concentrations were maximized for high salinity levels (≥2.22 dS m(-1)) of the pretreated CWW. PMID

    In the framework of ISAAC-International Studies on Asthma and Allergies in Childhood--the SIDRIA collaborative project--Studi Italiani sui Disturbi Respiratori nell'Infanzia e l'Ambiente--was established in order to estimate the prevalence of asthma, rinithis and eczema in ten geographic areas in Italy. Data collection spanned from October 1994 to March 1995. Overall 18,737 children 6-7 years old in the primary schools and 21,846 adolescents 13-14 years old in the secondary schools entered the study. The parents of pupils in both age groups filled in standardised questionnaires at home; furthermore both a traditional and a video questionnaire was administered at school to the adolescents. The overall response rate was 96.3%. Based on the interviews to the parents a prevalence of asthma of 9.0% in both age groups was estimated, with the lowest values in Cremona (4.6% children; 6.2% adolescents) and the highest in Roma (11.1% children; 10.4% adolescents). Parents also reported a higher prevalence of wheezing (7.7%) and dyspnea (5.3%) in the last year among children than among adolescents (4.7% and 3.4% respectively). Through the direct interview of the adolescents higher prevalence of asthma (10.4%), wheezing (10.3%) and dyspnea (7.8%) were estimated. Within a narrow range of variability, the reported prevalence of asthma and asthmatic symptoms in Trento and Cremona were the lowest and those in Roma, Empoli and Siena the highest. Nor an urban-rural neither a north-south gradient was detected. A higher prevalence of the same disorders was observed among females than males in the youngest age group, but this difference was no more evident among the adolescents.

The foreseen launch of new space platforms as the Sentinel satellites, providing good monitoring frequencies and free worldwide access to data is expected to increase the number of scientific and commercial activities exploiting EO data. In the sector of natural hazards the EO data have already demonstrated to be indispensable for the generation of information products for the prevention, and emergency management phases. In particular, the Italian Space Agency has promoted and funded, together with INGV, the development of dedicated infrastructures for the generation of advanced information products supporting different phases of the seismic and volcanic risk management cycles. These products were based mainly on SAR data from the COSMO-SkyMed 4-satellite constellation, and on optical data from commercial and scientific platforms, integrated with data from ground monitoring networks. During the last few years, such infrastructures have been tested under operational conditions and the products distributed to the Italian Civil Protection authority for validation and assessment. Here, with reference to the earthquake emergency management, we will present the infrastructure, the rapid mapping information products and some examples of activities during the latest seismic crises.

    2009-01-01

    Background: Drug-related infectious diseases are among the major health consequences of drug use, and any existing drug-related infection may predispose injecting drug users (IDUs) to other infections. Methods: We assessed among IDUs in Budapest, Hungary the prevalence of and vulnerability to selected drug-related infections and co-infections. The sample consisted of 186 participants recruited between October 2005 and December 2006. Results: We found 0% HIV, 37% HCV, 24% HAV, and 14% past HBV infection. Infections with Herpes 1 or 2, tuberculosis, Chlamydia, syphilis, and gonorrhoea were 79%, 12%, 7%, 4%, and 0%, respectively. Co-infection with HAV/HCV was 12%, HBV/HCV 9%, HAV/HBV 7%, and HAV/HBV/HCV 4%. Those over age 30, the ethnic Roma, and the homeless were more likely to have any hepatitis and a higher number of drug-related infections. Amphetamine injectors were more likely to have a higher number of drug-related infections and those who travelled within Hungary were more likely to have any STI. However, those who worked at least part time and those who were in treatment were less likely to have drug-related infections. Conclusions: These results highlight the need of interventions in Hungary to reach and focus on marginalized (Roma or homeless) IDUs and address not only injecting and sex risk, but also hygienic living and injecting conditions. Furthermore, structural interventions to increase social integration (working or being in treatment) may improve welfare and decrease drug use and infection risk tied to drug use/injection among disadvantaged, marginalized, mostly minority populations.

    We carried out two studies to test the hypothesis that genetic and environmental influences explain population group differences in general mental ability just as they do individual differences within a group. We estimated the heritability and environmentality of scores on the diagrammatic puzzles of the Raven's Coloured and/or Standard Progressive Matrices (CPM/SPM) from two independent twin samples and correlated these estimates with group differences on the same items. In Study 1, 199 pairs of 5- to 7-year-old monozygotic (MZ) and dizygotic (DZ) twins reared together provided estimates of heritability and environmentality for 36 puzzles from the CPM. These estimates correlated with the differences between the twins and 94 Serbian Roma (both rs=0.32; Ns=36; ps<0.05). In Study 2, 152 pairs of adult MZ and DZ twins reared apart provided estimates of heritability and environmentality for 58 puzzles from the SPM. These estimates correlated with the differences among 11 diverse samples including (i) the reared-apart twins, (ii) another sample of Serbian Roma, and (iii) East Asian, White, South Asian, Coloured and Black high school and university students in South Africa. In 55 comparisons, group differences were more pronounced on the more heritable and on the more environmental items (mean rs=0.40 and 0.47, respectively; Ns=58; ps<0.05). After controlling for measurement reliability and variance in item pass rates, the heritabilities still correlated with the group differences, although the environmentalities did not. Puzzles found relatively difficult (or easy) by the twins were those found relatively difficult (or easy) by the others (mean r=0.87). These results suggest that population group differences are part of the normal variation expected within a universal human cognition. PMID:17504738

The participants were also able to get involved with sample testing. Tutorial lectures were delivered at the school, addressing general and basic questions about nanotechnology, such as what they are, how does one go about them, what purposes can they serve. In tutorial sessions the nature of nanotechnology, the instruments of current use in its characterizations and the possible applicative uses were described at an introductory level. The first day was devoted to three sessions: Aerospace, defense, biomedicine. Electronics and mechanical properties. Materials and characterizations. The first session was opened by a lecture by J Kenny, who talked about the use of carbon nanotubes for polymer matrix nanocomposites. He reported how plasma functionalized single-walled carbon nanotubes (F-SWNTs) reacted with a primary aliphatic amine can be used for preparing an integrated nanotube composite

    The first attempts to georeference maps of early twentieth century produced by Istituto Geografico Militare (IGM, the Italian geodetic agency) for the city of Rome and its surroundings, reported residual errors bigger than errors observed on similar maps, while previous studies performed on maps one or two century older of the same area, showed similar or smaller errors. Possible explanations for errors of this entity can be the different systems of geodetic projection and geodetic datum or the derivation of some details from maps at smaller scale. In particular, the map of "Roma e Suburbio" of 1908 and the map of "Roma e l'Agro Romano" (representing a wider area) of 1912, both in scale 1:5000, have been studied. Parameters useful to perform the transformation of the geodetic system applied to these historical maps in more modern systems are not known. For such reason, until now the various attempts to georeference them were based on the collimation of points recognizable on modern cartographies such as corners of historical buildings. This approach often has offered unsatisfactory results. The historical geodetic system used the ellipsoid of Bessel oriented locally in the geodetic observatory in Genoa, while for the projection was used conformal Flamsteed one. In order to exclude that the deformations are due to the different projection (while comparing the original one to the transverse of Mercatore used both for the UTM and for the national system Gauss-Boaga used after 1940 and based on the Datum Roma40), we decided to study a transformation able to re-project the coordinates of points with known coordinates. This kind of transformation has also been performed by the IGM while transforming the existing cartographies of the whole Italian territory into the cartographic system Gauss-Boaga; for maps in scale 1:25000 with extension of around 10 km*10 km, the IGM estimated that the differences due to the different projection were irrelevant, therefore the

    One of the main limitations in the access to space for developing countries is the economical effort typically required by space missions. Secondly, space activity is a field of very high technology, requiring technical skills, education and practice, at a level which is seldom reached by developing countries. Interventions aimed to facilitate access to space for developing countries should be focussed primarily on the missions allowing access to space at reasonable cost. Moreover, perhaps more importantly, they should emphasize conducting the mission design, construction, ground testing and operation in orbit as an open activity, accessible to developing countries personnel, in order to set up an education process, which is not just selling a product ready satellite. Universities could have a very important role in this activity. Many Universities around the world have designed, built and launched small satellites. Università di Roma "La Sapienza" set up a program for the construction of small satellites in an academic environment, involving directly the students in the design, construction, ground testing and operation in orbit. The first satellite built in the framework of this program, UNISAT, was successfully launched in September 2000. The second, UNISAT-2, initially scheduled for launch in 2001, has been delayed by the launch provider to late 2002. These two satellites, based on a modular design, emphasizing ease of construction and assembly, weight roughly 10 kg. The realization of these satellites was made possible within the regular financing given to university research programs, keeping down cost by the use of commercial off the shelf components instead of space rated ones. The microsatellite experience at Università di Roma "La Sapienza", is going further with the development of a new nanosatellite bus, URSA MAIOR (Università di Roma "la SApienza" Micro Autonomous Imager in ORbit), aiming at cutting down cost and possibly improving performance.

    We develop simple relations to estimate dynamic displacement gradients (and hence the strains and rotations) during earthquakes in the lake-bed zone of the Valley of Mexico, where the presence of low-velocity, high-water content clays in the uppermost layers cause dramatic amplification of seismic waves and large strains. The study uses results from a companion article (Bodin et al., 1997) in which the data from an array at Roma, a lake-bed site, were analyzed to obtain displacement gradients. In this article, we find that the deformations at other lake-bed sites may differ from those at Roma by a factor of 2 to 3. More accurate estimates of the dominant components of the deformation at an individual instrumented lake-bed site may be obtained from the maximum horizontal velocity and displacement, ??max and umax, at the surface. The maximum surface strain ??max is related to ??max by ??max = ??max/C, with C ??? 0.6 km/sec. From the analysis of data from sites equipped with surface and borehole sensors, we find that the vertical gradient of peak horizontal displacement (??umax/??z) computed from sensors at 0 and 30 m equals (umax)z = 0/??z, ??z = 30 m, within a factor of 1.5. This is the largest gradient component, and the latter simple relation permits its estimation from surface records alone. The observed profiles of umax versus depth suggest a larger gradient in some depth range of 10 to 20 m, in agreement with synthetic calculations presented in Bodin et al. (1997). From the free-field recordings of the 19 September 1985 Michoacan earthquake, we estimate a maximum surface strain, ??max, between 0.05% and 0.11%, and a lower bound for the peak vertical gradient (??umax/??z) between 0.3% and 1.3%. This implies that (1) the extensive failure of water pipe joints during the Michoacan earthquake in the valley occurred at axial strains of about 0.1%, not 0.38% as previously reported, and (2) the clays of the valley behave almost linearly even at shear strain of about 1

    Two varieties of tomato fruits commonly available in Nigerian markets are the Roma VF and Ibadan local varieties of tomato fruits. The Roma VF fruits are oval in shape. It is a common type of cultivar in the Northern region of Nigeria and it is not susceptible to cracking. The Ibadan local variety of tomato fruits is a local variety commonly found on farmers fields in South-western region of Nigeria. They are highly susceptible to cracking. The Ibadan local variety was employed for this research. There are lots of benefits derived from the consumption of tomato fruits. The fruits can be made into tomato juice clarified with pectinases. Polygalacturonase is one of the pectinases used commercially in the clarification of fruit juice from different fruits. This study examined the production of polygalacturonase during the deterioration of tomato fruits by Aspergillus niger and the role of the purified polygalacturonase in the clarification of tomato juice. Tomato fruits of the Ibadan local variety were inoculated with mycelia discs containing spores of a 96-h-old culture of Aspergillus niger served as the inoculum. The organism from the stock culture was subcultured onto potato dextrose agar plates. The extraction of polygalacturonase after 10 days of incubation at 27 degrees C was carried out by homogenizing the fruits with liquid extractant using the MSE homogenizer after the deteriorated fruits had been chilled for 30 min inside a freezer. Control fruits were similarly treated except that sterile potato dextrose agar served as the inoculum. The effect of different temperature of incubation and different volume of enzyme on the tomato juice from the tomato fruits was investigated. Extracts from the inoculated fruits exhibited appreciable polygalacturonase activity. The juice with polygalacturonase was visually clearer and more voluminous than the juice treated with water for all parameters studied. The highest volume of juice was obtained after an incubation period

    Introduction The prevalence of cognitive impairment may be increased in adults with end-stage kidney disease compared with the general population. However, the specific patterns of cognitive impairment and association of cognitive dysfunction with activities of daily living and clinical outcomes (including withdrawal from treatment) among haemodialysis patients remain incompletely understood. The COGNITIVE impairment in adults with end-stage kidney disease treated with HemoDialysis (COGNITIVE-HD) study aims to characterise the age-adjusted and education-adjusted patterns of cognitive impairment (using comprehensive testing for executive function, perceptual-motor function, language, learning and memory, and complex attention) in patients on haemodialysis and association with clinical outcomes. Methods and analysis A prospective, longitudinal, cohort study of 750 adults with end-stage kidney disease treated with long-term haemodialysis has been recruited within haemodialysis centres in Italy (July 2013 to April 2014). Testing for neurocognitive function was carried out by a trained psychologist at baseline to assess cognitive functioning. The primary study factor is cognitive impairment and secondary study factors will be specific domains of cognitive function. The primary outcome will be total mortality. Secondary outcomes will be cause-specific mortality, major cardiovascular events, fatal and non-fatal myocardial infarction and stroke, institutionalisation, and withdrawal from treatment at 12 months. Ethics and dissemination This protocol was approved before study conduct by the following responsible ethics committees: Catania (approval reference 186/BE; 26/09/2013), Agrigento (protocol numbers 61–62; 28/6/2013), USL Roma C (CE 39217; 24/6/2013), USL Roma F (protocol number 0041708; 23/7/2013), USL Latina (protocol number 20090/A001/2011; 12/7/2013), Trapani (protocol number 3413; 16/7/2013) and Brindisi (protocol number 40259; 6/6/2013).

    The Quaternary Roman Volcanic Province extends for over 200 km along the Tyrrhenian margin of the Italian peninsula and is composed of several caldera complexes with significant associated geothermal potential. In spite of the massive programs of explorations conducted by the then state-owned ENEL and AGIP companies between the 1970s and 1990s, and the identification of several high enthalpy fields, this resource remains so far unexploited, although it occurs right below the densely populated metropolitan area of Roma capital city. The main reason for this failure is that deep geothermal reservoirs are associated with fractured rocks, the secondary permeability of which has been difficult to predict making the identification of the most productive volumes of the reservoirs and the localisation of productive wells uncertain. As a consequence, almost half of the many exploration deep bore-holes drilled in the area reached a dry target. This work reviews available data and re-assesses the geothermal potential of caldera-related systems in Central Italy, by analysing in detail the case of the Colli Albani caldera system, the closest to Roma capital city. A GIS based approach identifies the most promising reservoir volumes for geothermal exploitation and uses an improved volume method approach for the evaluation of geothermal potential. The approach is based on a three dimensional matrix of georeferenced spatial data; the A axis accounts for the modelling of the depth of the top of the reservoirs based on geophysical and direct data; the B axis accounts for the thermal modelling of the crust (i.e. T with depth) based on measured thermal gradients. Both A and B data are necessary but not sufficient to identify rock volumes actually permeated by geothermal fluids in fractured reservoirs. We discuss the implementation of a C axis that evaluates all surface data indicating permeability in the reservoir and actual geothermal fluid circulation. We consider datasets on: i

    Air pollution, caused by fuel industries and urban traffic and its environmental impact, are of considerable interest to studies in air quality. In this paper, the monitoring of the air pollution over urban areas in Italy through Aerosol Optical Thickness (AOT) data retrieved from Moderate Resolution Imaging Spectroradiometer (MODIS) measurements is presented. The high spatio-temporal frequency of MODIS AOT products (twice per day at 470nm, 1km full resolution) demonstrates that this satellite can be potentially used to routinely monitor the air pollution over land, especially urban area, which is the main source of aerosol particles. In this work AOT data derived by MODIS from November 2010 to February 2011 (winter period) and from May 2011 to August 2011 (summer period) were compared with AOT measurements from 6 different Aerosol Robotic Network (AERONET) stations over Italy (Bari, Lecce, Roma, Ispra, Potenza, Etna). The statistical analysis shows a good agreement between the ground based AOT measurements and the values retrieved using space based sensors, as shown in Figure 1. For all the stations the mean error is negligible, with a correlation ranging from 0.725 (in the worst case) to 0.96 (see Table 1). Moreover, LANDSAT-panchromatic images were used to discriminate urban and rural areas, based on the typical finger-like projections of urban land uses. The results of this study will be presented and commented. Acknowledgements This work was funded by Apulian Region in the framework of the ECOURB project.

    Purpose: The aim of this study was to evaluate the pregnancy outcomes in women with Hodgkin lymphoma (HL) diagnosis, treated between 1972 and 1999 at Department of Radiotherapy and Hematology of University 'Sapienza' of Roma. Methods and Materials: We retrospectively studied 99 female patients that conceived after treatment for HL. Fifty-nine (59%) were treated with chemotherapy and radiotherapy, 32 (32%) with radiotherapy alone as supradiaphragmatic or as infradiaphragmatic and 8 (8%) patients with chemotherapy alone. Results: Ninety-nine patients reported 145 pregnancies. We observed 132 deliveries (2 of them twin births) after a median of 55 months (range, 14-278 months) from the end of therapy. Twelve women (12%) experienced 13 miscarriages after a median of 50 months (range, 13-120) from the end of therapy. We recorded 9/132 (7%) premature births and 3/134 babies (2%) were underweight at the time of birth. We recorded 2 cases of congenital malformations. No statistical differences were recorded when adverse pregnancy outcomes were analyzed with respect to chemotherapy alone, radiotherapy alone, or combined therapy. Conclusions: No significant associations between pregnancy outcomes and therapeutic approaches were found. In particular, the infradiaphragmatic radiotherapy showed no statistical association with miscarriages, premature birth, and low birth weight at term when compared with other therapeutic approaches.

    Ovarian masses, a common finding among pre- and post-menopausal women, can be benign or malignant. Ovarian cancer is the leading cause of death from gynecologic malignancy among women living in industrialized countries. According to the current guidelines, measurement of CA125 tumor marker remains the gold standard in the management of ovarian cancer. Recently, HE4 has been proposed as emerging biomarker in the differential diagnosis of adnexal masses and in the early diagnosis of ovarian cancer. Discrimination of benign and malignant ovarian tumors is very important for correct patient referral to institutions specialized in care and management of ovarian cancer. Tumor markers CA125 and HE4 are currently incorporated into the "Risk of Ovarian Malignancy Algorithm" (ROMA) with menopausal status for discerning malignant from benign pelvic masses. The availability of a good biomarker such as HE4, closely associated with the differential and early diagnosis of ovarian cancer, could reduce medical costs related to more expensive diagnostic procedures. Finally, it is important to note that HE4 identifies platinum non-responders thus enabling a switch to second line chemotherapy and improved survival.

    "PEER BULLYING" IN CZECH PRIMARY SCHOOLS: A QUESTION OF INTERPRETATION—This article questions adults' reports of an alleged increase in peer bullying at Czech primary schools. A survey on the school climate revealed that the pupils see it as a generally positive one and consider their relationships to be good. However, compared to France, their behaviour towards the adults is aggressive and rude. This apparent contradiction is linked to a conflict between the educational norms carried over from the old regime (behavioural control and conformism) and the new socio-economic paradigms (critical thinking and free enterprise). Public opinion, the media and a number of scientifically-questionable studies have drawn attention to the phenomenon of peer bullying ( šikana), and applied an imported concept to describe it ( school bullying). This makes it possible to avoid questioning the part played by the adults, the school and the researchers; justify segregating pupils from socially, culturally or economically disadvantaged backgrounds (Roma); and facilitate the country's socio-economic inclusion in the European Union by highlighting educational problems about whose nature there is general agreement.

    Industries nowadays continuously produce new types of inks for markers and pens, so new different graffiti appear . In this paper laser cleaning tests on 41 new marker and pen types ( fluorescent, permanent, water-based, acrylic tempera, metallic paint, waterproof inks ), applied into laboratory on different litho- type samples (Chianca, Travertino di Roma, Tufo Carparo fine grain, Sabbie), typical stones employed in much more monuments in Puglia and Italian architectures were carried out. The same ones, were exposed for twelve months to outdoor ageing, subject to sunshine, rain, wind, IR and UV solar radiations. Ablation experiments and tests by using different cleaning techniques, each one in Dry and Wet condition (classic technique, Daurelio technique 1 and Daurelio technique 2 and others new techniques) and two different Nd:YAG laser systems (Palladio by QUANTA SYSTEM and SMART CLEAN II by EL.EN.), were adopted. The experimental modes, N-Mode (1064nm - 150, 300 and 500 μs pulse duration), Q-Switch (1064nm - 8 ns pulse duration) and SFR (Short Free Running - 1064 nm - 40 to 110μs pulse duration) were tested on each marked stones. It was found that according to the different ink types and stone substrate, Q-Switch laser cleaning ablation with optimized laser technique are the best solution to marker an pen graffiti removal. The work is still in progress.

    This paper presents findings from a collaborative inquiry project that explored teaching approaches that highlight the significance of multilingualism, multimodality, and multiliteracies in classrooms with high numbers of English language learners (ELLs). The research took place in an inner city elementary school with a large population of recently arrived and Canadian-born linguistically and culturally diverse students from Gambian, Indian, Mexican, Sri Lankan, Tibetan and Vietnamese backgrounds, as well as a recent wave of Roma students from Hungary. A high number of these students were from families with low-SES. The collaboration between two Grade 3 teachers and university-based researchers sought to create instructional approaches that would support students' academic engagement and literacy learning. In this paper, we described one of the projects that took place in this class, exploring how a descriptive writing unit could be implemented in a way that connected with students' lives and enabled them to use their home languages, through the creation of multiple texts, using creative writing, digital technologies, and drama pedagogy. This kind of multilingual and multimodal classroom practice changed the classroom dynamics and allowed the students access to identity positions of expertise, increasing their literacy investment, literacy engagement and learning.

    The most commonly used method for serotyping Salmonella spp. is based on the Kaufmann-White scheme, and is composed of serological reactions using antibodies to LPS agglutinins. The multiplex PCR used in this investigation was established by Kim et al. to serotype the 30 most common clinical Salmonella serotypes, as determined by CDC. The PCR assay consists of two five-plex reactions and a single two-plex PCR reaction, based on six genetic loci from Salmonella enterica serotype Typhimurium and four loci from S. enterica serotype Typhi. In this investigation, we further evaluated the method for serotyping Salmonella spp. using a reference collection, environmental samples collected from a Mid-Atlantic region tomato farm study, four food matrices spiked with different Salmonella serotypes and a proficiency test. The PCR assay was first evaluated using DNA isolated from pure cultures of isolates obtained from various clinical and environmental samples, and then DNA isolated from broth cultures of food matrices of "Red round" and Roma tomatoes, Romaine lettuce, green onions and Serrano peppers spiked with serotypes Newport, Typhimurium, Javiana and Saintpaul, respectively. The results showed that the PCR assay correctly serotyped Salmonella spp. from the clinical, environmental, spiked food matrices, and proficiency test samples. These findings are significant because the PCR assay was successful in the identification of Salmonella in the spiked samples in a broth culture containing other non-salmonella organism. This method may be a useful resource for the food safety community. PMID:22608224

    Quarries, caves and mines often contain fossils. During the '30s in Rome, the urban expansion needs for building materials such as gravel, sand and clay were extracted from quarries that surrounded the city. One of these quarries in particular, in the area of Saccopastore (Nomentana area 3 km from the University Sapienza Roma) returned an ancient human fossil skull belonging to a Neanderthal (most likely a female) who lived in Latium about 120,000 years ago. Detailed studies of this fossil were carried out by Sergio Sergi, the son of the founder of the Museum of Anthropology in Rome, Giuseppe Sergi. The museum was founded in 1884 and was later transferred to the University City (1934) where it is still located. Professor Maria Luana Belli, a science teacher in the Liceo Scientifico "G. Keplero" is a volunteer and collaborator with the Museum "G. Sergi", and she and her students retrace the places of the discovery on the trail of the Neanderthals, for understanding the evolution of the territory in a perspective of interdisciplinary teaching.

    Clinical governance of healthcare and community services by healthcare organizations requires the use of validated tools for identifying the specific healthcare needs of the local population. The population served by a local health organization may be large and although data regarding this population as a whole is useful for a preliminary evaluation, it may be too generic for an accurate estimation of the healthcare needs at the district level since different districts may face different challenges and have profoundly different realities. In this context, it can be strategically useful to use a system of indicators targeted at districts, the latter regarded as the basic unit of the health care system and characterized by a relatively constant structure and size.A set of district indicators has been developed and adopted by a local health authority in Rome (Italy) "ASL Roma B", as part of a collaborative project with the Public Health Agency of the Lazio region. In this paper, we present the main results of the first four years of implementation of the system (from 2007 to 2010).The data shows that even within a metropolitan health organization serving an apparently homogeneous population, health needs, provision of services and outcomes may vary greatly between different districts suggesting the adoption of diverse operational strategies.

    We investigated the oxygen uptake response (V.O (2)) to a 1500-m test conducted using a competition race strategy. On an outdoor track, eleven middle-distance runners performed a test to determine V.O (2max), velocity associated with V.O (2max) (v-V.O (2max)) and a supramaximal 1500-m running test (each test at least two days apart). V.O (2max) response was measured with the use of a miniaturised telemetric gas exchange system (Cosmed, K4, Roma, Italy). The 1500-m running test was performed at a mean velocity of 107. 6 + 2 % v-V.O (2max). The maximal value of oxygen uptake recorded during the 1500-m test (V.O (2peak)) was reached by subjects at 75.9 + 7.5 s (mean + SD) (i.e., 459 +/- 59 m). The time to reach V.O (2max) (TV.O (2peak)) and the start velocity (200- to 400-m after the onset of the 1500 m) expressed in % v-V.O (2max) were negatively and significantly correlated (p < 0.05), but our results indicate that a fast start does not necessarily induce a good performance. These results suggest that V.O (2max) is reached by all the subjects at the onset of a simulated 1500-m running event and are therefore in contrast with previous results obtained during treadmill running.

    Climate plays an important role in the distribution of species. A given species may adjust to new conditions in-place, move to new areas with suitable climates, or go extinct. Scientists and conservation practitioners use mathematical models to predict the effects of future climate change on wildlife and plan for a biodiverse future. This 8-page fact sheet written by David N. Bucklin, Mathieu Basille, Stephanie S. Romañach, Laura A. Brandt, Frank J. Mazzotti, and James I. Watling and published by the Department of Wildlife Ecology and Conservation explains how, with a better understanding of species distribution models, we can predict how species may respond to climate change. The models alone cannot tell us how a certain species will actually respond to changes in climate, but they can inform conservation planning that aims to allow species to both adapt in place and (for those that are able to) move to newly suitable areas. Such planning will likely minimize loss of biodiversity due to climate change.

    The Samnites are an Iron Age protohistoric people from the central region of Italy. The skeletal remains are from the Alfedena necropolis, 6th through 5th centuries B.C. Macchiarelli et al. (Antropologia Contemporanea 4 (1981) 239-243) were the first to report on cranial trauma for this population, presenting four cases with extreme injuries. We re-examined this well documented skeletal population for additional examples of trauma. Previously unexamined remains from Alfedena, excavated at the turn of the 20th century, are also included in our analysis (Mariani. 1901. "Aufidena", ricerche archeologiche e storiche del Sannio settentrionale. Roma: Acc Naz Dei Lincei). Of the 209 adult crania examined, 12.9% of them exhibited trauma. Analysis of location and frequency of cranial trauma revealed that cranial injuries to the head appear to originate from all directions. The high rate of cranial trauma underscores the violent circumstances experienced during the Iron Age protohistoric period of central Italy. Males are much more likely to exhibit cranial injury than females (P = 0.009). We conclude that the injuries received by Samnite male farmer-warriors occurred while defending pastoral-agricultural resources. Trauma rates are similar for some Iron Age populations and not for others. Behavior associated with violence during the Iron Age period can not be generalized for all populations found in Italy.

    We aimed to characterise the phenotype and perform genetic studies in a family of Roma/Gypsy ethnicity, affected by epilepsy. The mean age at onset of epilepsy was 9 years and seizures persisted into adulthood. Antecedent febrile convulsions were rare. Seizure semiology and EEG findings suggested mesial temporal lobe origin with no evidence of hippocampal sclerosis. Seizures frequently generalised. Family structure suggested autosomal-dominant inheritance with incomplete penetrance. Linkage analysis identified a single novel locus on 7p21.3, corresponding to the expected maximum in the family. Previously reported temporal lobe epilepsy (TLE) loci were definitely excluded. The minimal shared haplotype of 2.4cM (1.3Mb) was not observed in other affected families or controls from the same population. Three brain-expressed validated genes in the critical region represent potential candidates. We have identified an epilepsy syndrome with temporal lobe seizures commonly evolving to generalised convulsions. Linkage to 7p21.3 adds up to a total of five currently known FTLE loci.

    On 10 March 2010, due to the heavy rainfall that occurred on the previous days, the Montaguto earthflow reactivated, involving the road SS 90 "Delle Puglie", as had happened previously in May 2005 and in September 2009, and reaching the Roma-Bari railway. This determined a special attention of the National Civil Protection Department and a widespread monitoring and analysis program was initiated. A monitoring activity using GB-InSAR (Ground Based Interferometric Synthetic Aperture Radar) system began, in order to investigate the landslide kinematics, to plan urgent safety measures for risk mitigation and to design long term stabilization work. In this paper the GB-InSAR monitoring system results and its applications in the Observational Method (OM) approach are presented. The paper also highlights how the OM based on the GB-InSAR technique can produce savings in cost and time on engineering projects, without compromising safety, and how it can also benefit the geotechnical community by increasing scientific knowledge. This study focuses on the very much active role played by the monitoring activities, in both the design and plan modifications; with a special consideration for the emergency phase.

    Based on the extension reaction of a telomerase substrate (TS) primer in the presence of the telomerase, strand-displacement process to perform more stable longer duplex chain, and stepwise hydrolysis of mononucleotides from the blunt or the recessed 3'-hydroxyl termini of duplex DNA in the presence of Exonuclease III (Exo III), an amplified fluorescence detection of telomerase activity in the cancer cells was described in this manuscript. A fluorescence probe DNA, a quencher DNA, and a TS primer were mixed to construct a three-chain DNA structure and a two-chain DNA structure because the amount of the TS primer was less than the other two DNA. In the presence of the telomerase, the quencher DNA was replaced from the probe DNA and the telomerase activity could be determined with the fluorescence enhancement. The telomerase activity in HeLa extracts equivalent to 6-2000 cells was detected by this method. Moreover, the strategy was further proved by using telomerase extracted from Romas cells. With the multiple rounds of isothermal strand displacement and the hydrolysis process, constituted consecutive of signal amplification for the novel detection paradigm that allowed measuring of telomerase activity in crude cancer cell extracts confirmed the reliability and practicality of the protocol, which reveal this platform holds great promise in the biochemical assay for the telomerase activity in early diagnosis for cancers.

    The realization of low-cost instruments with high technical performance is a goal that deserves some efforts in an epoch of fast technological developments; indeed, such instruments can be easily reproduced and therefore allow new research programs to be opened in several observatories. We realized a fast optical photometer based on the SiPM technology, using commercially available modules. Using low-cost components, we have developed a custom electronic chain to extract the signal produced by a commercial MPPC module produced by Hamamatsu Photonics, in order to obtain submillisecond sampling of the light curve of astronomical sources (typically, pulsars). In the early 2011 February, we observed the Crab pulsar with the Cassini telescope with our prototype photometer, deriving its period and power spectrum and the shape of its light curve, in very good agreement with the results obtained in the past with other instruments. Based on observations made with the 152 cm Cassini telescope at the Loiano station of the Bologna Observatory and with the 50 cm telescope of the Università di Roma "La Sapienza" at Vallinfreda (Rome).

    Lead, cadmium, arsenic, and zinc were quantified in mine wastes and in soils mixed with mine wastes. Metal concentrations were found to be heterogeneous in the wastes. Iceberg lettuce, Cherry Belle radishes, Roma bush beans, and Better Boy tomatoes were cultivated in mine wastes and in waste-amended soils. Lettuce and radishes had 100% survival in the 100% mine waste treatments compared to 0% and 25% survival for tomatoes and beans, respectively. Metal concentrations were determined in plant tissues to determine uptake and distribution of metals in the edible plant parts. Individual soil samples were collected beneath each plant to assess metal content in the immediate plant environment. This analysis verified heterogeneous metal content of the mine wastes. The four plant species effectively accumulated and translocated lead, cadmium, arsenic, and zinc. Tomato and bean plants contained the four metals mainly in the roots and little was translocated to the fruits. Radish roots accumulated less metals compared to the leaves, whereas lettuce roots and leaves accumulated similar concentrations of the four metals. Lettuce leaves and radish roots accumulated significantly more metals than bean and tomato fruits. This accumulation pattern suggests that consumption of lettuce leaves or radish roots from plants grown in mine wastes would pose greater risks to humans and wildlife than would consumption of beans or tomatoes grown in the same area. The potential risk may be mitigated somewhat in humans, as vegetables grown in mine wastes exhibited stunted growth and chlorosis.

    In order to improve the hospital information system of the Chilean University Hospital, the Veterinary Medicine School of Universidad de Chile made a research cooperation with Università San Raffaele Roma to develop and test a new release of the O3-Vet software application. O3-Vet was selected by the Chilean University mainly for two reasons: (1) it uses human medicine standardized technologies such as "Health Level 7" (HL7) and "Integrating the Healthcare Enterprise" (IHE), which allow a good level of data sharing and hospital management; (2) it is open source, which means it can be adapted to specific hospital needs. In the new release, a subset of diagnostic terms was added from the "Systematized Nomenclature of Medicine Clinical Terms" (SNOMED CT), selected by the "American Animal Hospital Association" (AAHA) to standardize the filing of clinical data and its retrieval. Results from a limited survey of veterinarians of the University (n=9) show that the new release improved the management of the Chilean University Hospital and the ability to retrieve useful clinical data.

    SUMMARY In 2008, nationwide investigations of a Salmonella serotype Saintpaul outbreak led first to consumer warnings for Roma and red round tomatoes, then later for jalapeño and serrano peppers. In New Mexico, where there were a large number of cases but no restaurant-based clusters, the NM Department of Health and the Indian Health Service participated with CDC in individual-level and household-level case-control studies of infections in New Mexico and the Navajo Nation. No food item was associated in the individual-level study. In the household-level study, households with an ill member were more likely to have had jalapeño peppers present during the exposure period and to have reported ever having serrano peppers in the household. This report illustrates the complexity of this investigation, the limitations of traditional individual-level case-control studies when vehicles of infection are ingredients or commonly eaten with other foods, and the added value of a household-level study.

    We present a new method for identifying blazar candidates by examining the locus, i.e., the region occupied by the Fermi {gamma}-ray blazars in the three-dimensional color space defined by the WISE infrared colors. This method is a refinement of our previous approach that made use of the two-dimensional projection of the distribution of WISE {gamma}-ray-emitting blazars (the Strip) in the three WISE color-color planes. In this paper, we define the three-dimensional locus by means of a principal component analysis of the color distribution of a large sample of blazars composed of all the ROMA-BZCAT sources with counterparts in the WISE All-Sky Catalog associated with {gamma}-ray sources in the second Fermi-LAT catalog (2FGL; the WISE Fermi blazars sample, WFB). Our new procedure yields a total completeness of c {sub tot} {approx} 81% and a total efficiency of e {sub tot} {approx} 97%. We also obtain local estimates of the efficiency and completeness as functions of the WISE colors and galactic coordinates of the candidate blazars. The catalog of all WISE candidate blazars associated with the WFB sample is also presented, complemented by archival multi-frequency information for the alternative associations. Finally, we apply the new association procedure to all {gamma}-ray blazars in the 2FGL and provide a catalog containing all the {gamma}-ray candidate blazars selected according to our procedure.

    We report the results of our exploratory program carried out with the southern Astrophysical Research telescope aimed at associating counterparts and establishing the nature of the Fermi Unidentified γ-ray Sources (UGSs). We selected the optical counterparts of six UGSs from the Fermi catalog on the basis of our recently discovered tight connection between infrared and γ-ray emission found for the γ-ray blazars detected by the Wide-Field Infrared Survey Explorer in its all-sky survey. We perform for the first time a spectroscopic study of the low-energy counterparts of the Fermi UGSs, in the optical band, confirming the blazar-like nature of the whole sample. We also present new spectroscopic observations of six active galaxies of uncertain type associated with Fermi sources which appear to be BL Lac objects. Finally, we report the spectra collected for six known γ-ray blazars belonging to the Roma BZCAT that were obtained to establish their nature or better estimate their redshifts. Two interesting cases of high redshift and extremely luminous BL Lac objects (z ≥ 1.18 and z ≥ 1.02, based on the detection of Mg ii intervening systems) are also discussed.

    In 3D survey the aspects most discussed in the scientific community are those related to the acquisition of data from integrated survey (laser scanner, photogrammetric, topographic and traditional direct), rather than those relating to the interpretation of the data. Yet in the methods of traditional representation, the data interpretation, such as that of the philological reconstruction, constitutes the most important aspect. It is therefore essential in modern systems of survey and representation, filter the information acquired. In the system, based on the integrated survey that we have adopted, the 3D object, characterized by a cloud of georeferenced points, defined but their color values, defines the core of the elaboration. It allows to carry out targeted analysis, using section planes as a tool of selection and filtering data, comparable with those of traditional drawings. In the case study of the Abbey of Casamari (Veroli), one of the most important Cistercian Settlement in Italy, the survey made for an Agreement with the Ministry of Cultural Heritage and Activities and Tourism (MiBACT) and University of RomaTre, within the project "Accessment of the sismic safety of the state museum", the reference 3D model, consisting of the superposition and geo-references data from various surveys, is the tool with which yo develop representative models comparable to traditional ones. It provides the necessary spatial environment for drawing up plans and sections with a definition such as to develop thematic analysis related to phases of construction, state of deterioration and structural features.

    The paper presents the trajectory designed by the Italian joint team Politecnico di Torino & Sapienza Università di Roma (Team5), winner of the 6th edition of the Global Trajectory Optimization Competition (GTOC6). In the short time available in these competitions, Team5 resorted to basic knowledge, simple tools and a powerful indirect optimization procedure. The mission concerns a 4-year tour of the Jupiter Galilean moons. The paper explains the strategy that was preliminarily devised and eventually implemented by looking for a viable trajectory. The first phase is a capture that moves the spacecraft from the arrival hyperbola to a low-energy orbit around Jupiter. Six series of flybys follow; in each one the spacecraft orbits Jupiter in resonance with a single moon; criteria to construct efficient chains of resonant flybys are presented. Transfer legs move the spacecraft from resonance with a moon to another one; precise phasing of the relevant moons is required; mission opportunities in a 11-year launch window are found by assuming ballistic trajectories and coplanar circular orbits for the Jovian satellites. The actual trajectory is found by using an indirect technique.

    During the past several summers the Soprintendenza Archeologica di Roma and the American Academy in Rome have carried out collaborative excavations on the late Roman complex located on the northeastern slope of the Palatine Hill. The late Roman complex is situated on the lower slopes of the area commonly known as Vigna Barberini, after its 17th century owners. Because this area, as well as most of the east slope of the Palatine, has never been systematically explored, it remains from an archaeological point of view essentially unknown. The overall aim of the excavations is to investigate layout, function, and occupational history of a mid-to-late imperial building complex located just southwest of the Arch of Constatine. Part of this international project is the chemical characterization of Roman fineware pottery from archaeological excavations on the site of the imperial palaces. Excavation has yielded more than 8 t of Late Roman and Early Medieval pottery (circa 3rd to 10th centuries A.D.). Many classes of pottery have already been classified by their provenance based on distribution patterns, but others require chemical characterization to separate similar clays. To that end routine neutron activation analysis (NAA) methods have been used to analyze {approximately}200 pieces of pottery.

    An orientable deployed solar array system for 1-5 kg weight nanospacecraft is described, enhancing the achievable performance of these typically power-limited systems. The system is based on a deployable solar panel system, previously developed with cooperation between Laboratorio di Sistemi Aerospaziali of University of Roma “la Sapienza” and the company IMT (Ingegneria Marketing Tecnologia). The system proposed is a modular one, and suitable in principle for the 1U, 2U and 3U standard Cubesat bus, even if the need for three axis attitude stabilization makes it typically preferred for 3U Cubesats. The size of each solar panel is the size of a lateral Cubesat surface. A single degree of freedom maneuvering capability is given to the deployed solar array, in order to follow the apparent motion of the sun as close as possible, given the mission requirements on the spacecraft attitude. Considerable effort has been devoted to design the system compatible with the Cubesat standard, being mounted outside on the external spacecraft structure, without requiring modifications on the standard prescriptions. The small available volume is the major constraint, which forces to use miniaturized electric motor technology. The system design trade-off is discussed, leading to the selection of an architecture based on two independently steerable solar array wings.

    The achievements of mankind are based on the interaction of discovery, invention, and innovation. Once man learnt how to utilize the laws of nature, he advanced to a being who attained greatest strength upon other creatures. An analogy can be drawn for civilisations: Those conducting fundamental research will gain strategical power. Among the sciences, astronomy and astrophysics provide the largest potential for discoveries that reach far beyond our intellectual limits. They trigger technology and have a decisive impact on the society. Within the frame of this nationwide initiative, the Institute for Space Astrophysics and Planetology (Istituto di Astrofisica e Planetologia Spaziali, IAPS), with the collaboration of OAR (Osservatorio Astronomico di Roma), organized and realized in 2012 a number of events that took place in Rome. Thanks to the wide range of scientific activities carried out by IAPS scientists, topics ranged from Moon exploration to shooting stars, from gravity to stars' birth. In each appointment, kids had the chance to learn about planetology and astrophysics, participating to games, creating clay models, building paper spacecrafts, listening to stories and…just having fun. In this talk we will present some of the most interesting and successful stories in the Astrokids project.

    An individual's neurodevelopmental and cognitive sequelae to negative early experiences may, in part, be explained by genetic susceptibility. We examined whether extreme differences in the early caregiving environment, defined as exposure to severe psychosocial deprivation associated with institutional care compared to normative rearing, interacted with a biologically informed genoset comprising BDNF (rs6265), COMT (rs4680), and SIRT1 (rs3758391) to predict distinct outcomes of neurodevelopment at age 8 (N = 193, 97 males and 96 females). Ethnicity was categorized as Romanian (71%), Roma (21%), unknown (7%), or other (1%). We identified a significant interaction between early caregiving environment (i.e., institutionalized versus never institutionalized children) and the a priori defined genoset for full-scale IQ, two spatial working memory tasks, and prefrontal cortex gray matter volume. Model validation was performed using a bootstrap resampling procedure. Although we hypothesized that the effect of this genoset would operate in a manner consistent with differential susceptibility, our results demonstrate a complex interaction where vantage susceptibility, diathesis stress, and differential susceptibility are implicated.

    Recombination effects can affect the detectors used for the dosimetry of radiotherapy fields. They are important when using ionization chambers, especially in liquid-filled ionization chambers, and should be corrected for. The introduction of flattening-filter-free accelerators increases the typical dose-per-pulse used in radiotherapy beams, which leads to more important recombination effects. Diamond detectors provide a good solution for the dosimetry and quality assurance of small radiotherapy fields, due to their low energy dependence and small volume. The group of Università di Roma Tor Vergata has developed a synthetic diamond detector, which is commercialized by PTW as microDiamond detector type 60019. In this work we present an experimental characterization of the collection efficiency of the microDiamond detector, focusing on high dose-per-pulse FFF beams. The collection efficiency decreases with dose-per-pulse, down to 0.978 at 2.2 mGy/pulse, following a Fowler-Attix-like curve. On the other hand, we have found no significant dependence of the collection efficiency on the pulse repetition frequency (or pulse period).

    The aim of this study was to evaluate the impact of health care planning and management guidelines, elaborated by the Lazio regional healthcare authority, on the organizational structure and operational processes of local health authorities and, more specifically, of the Roma C local health authority. The guidelines are made up of three volumes and mainly describe an operational model, rather than being a set of standard references aimed at standardizing the quality of information low systems in local healthcare authorities. The guidelines are essentially a didactic text, and were elaborated by a consulting firm, Engineering Management Consulting, on behalf of the Lazio regional authority. In the first section, the main concepts are defined, while in subsequent sections, detailed models regarding the specific subject matter are described. Although the guidelines represent a useful tool in the process of converting local health authorities of the Lazio region into "business" organizations, so far they have been of use only in the first phase of assessment of different organizational models for healthcare planning and management. There is still a long way ahead towards defining standard procedures and references for describing activities and costs. This is what should hopefully be achieved briefly and which will necessarily require the introduction of a data warehouse and business intelligence software that will allow monitoring of activities and making short term predictions through the use balanced scorecards and data mining.

    Background Epidemiological investigations were carried out in the Lazio Region to assess the status of canine filariosis and to evaluate the actual risk for veterinary and medical public health. Methods Since August 2001 to June 2003, a total of 972 canine blood samples, collected in public kennels and from private owners animals of the 5 Provinces of the Region, were tested. The presence of filarial parasites was evaluated by microscopy and bio-molecular techniques; the species identification was performed by means of the same diagnostic tools. Results A total of 17/972 (1.75%; 95%CI 1.06%–2.85%) blood samples were parasitized by D. repens,13 out them drawn by dogs resident in the Province of Roma, and 4 in the other provinces. Multivariate analysis was performed in order to evaluate the association between filariosis and risk factors. The origin from coastal territories seems to be a significant risk factor to acquire the infection. Conclusion This is the first report of canine filariosis in the Lazio Region, where D. repens was before reported only in foxes. The risk of human zoonotic infection is stressed, and the absence of other filarial species is discussed PMID:16185352

    In a recently published manuscript [Guidoboni, E., Boschi, E., 2006. Vesuvius before the 1631 eruption, EOS, 87(40), 417 and 423]; [Guidoboni, E. (Ed.), 2006. Pirro Ligorio, Libro di diversi terremoti (1571), volume 28, codex Ja II 15, Archivio di Stato di Torino, Edizione Nazionale delle Opere di Pirro Ligorio, Roma, De Luca, 261 pp], Pirro Ligorio gives a detailed description of the phenomena occurring in the crater area of Vesuvius volcano, in 1570-1571 and previous years. Here, these phenomena are interpreted as the first clearly documented signals of unrest of this volcanic system caused by the shallow emplacement of a magma batch and leading to the 1631 eruption. Our interpretation is mainly based on the present understanding of the fluid geochemistry of magmatic-hydrothermal systems. In this way, it is possible to conclude that: (i) incandescent rocks were present at the surface, with temperatures > 500 °C approximately and (ii) either a magmatic-dominated or a magmatic-hydrothermal-type of conceptual geochemical model applies to Vesuvius in 1570-1571 and preceding years. The Ligorio's picture represents the first clear evidence that the magma involved in the 1631 eruption was present under the volcano more than sixty years before the eruption. Moreover, its emplacement produced a series of phenomena which were clearly observed although not understood at that time. A similar phenomenological pattern should be easily detected and correctly interpreted at present or in the future.

  4. Assessing the impact of large-scale dewatering on fault-controlled aquifer systems: a case study in the Acque Albule basin (Tivoli, central Italy)

    The development of large-scale bedrock quarry operations often requires high-volume and long-term groundwater extraction to maintain a sustainable working environment. These dewatering activities often influence groundwater levels and flow patterns regionally. In the present study, the influence of the dewatering of the travertine quarry operations near the city of Tivoli, Italy, are quantitatively investigated through an integrated analysis of field data and numerical modeling. Lowering of regional groundwater levels in the vicinity of the quarry has led to destructive land subsidence and alterations to the flow system sustaining a hot-spring area. The study employs a finite element numerical model (FEFLOW) to evaluate and quantify the impact of the extensive dewatering on fault-controlled regional groundwater flow in the Acque Albule basin. By incorporating the physical field data and historical hydrologic information, the numerical model was calibrated against three groundwater scenarios, reproducing the effects of different exploitation activities, coupled with natural changes over the course of the quarry operation. The results indicate that groundwater withdrawals by the mining industry and by "Terme di Roma" spa resulted in the cessation of flow from the primary thermal spring and a drop in the phreatic level in the area consequently affected by land subsidence.

  5. Fall of the iron curtain: male life expectancy in Slovakia, in the Czech Republic and in Europe.

    Year 1989, the fall of communism, represents a dramatic watershed. Changes and reforms reflected also upon the quality of health care and the health of populations living on eastern side of the divide. Until then, Eastern Europe had free socialized medicine, albeit troubled by lack of up-to-date medications and absence of modern diagnostic equipment. Noting the admirable progress in health in some regions of the former Soviet empire during its transformation provides invaluable sociological lesson. Furthermore, focusing on health trends in two Central European countries, the Czech republic (CZ) and Slovakia (SK), brings about another quality to such evaluation. Dramatic improvement in the life expectancy (LE) is represented mainly in the decrease of cardiovascular mortality, more in the Czech Republic than in Slovakia. Favorable trend of male LE in the Czech Republic exceeded several established West European countries, while in Russia, Belarus and Ukraine the life expectancy actually deteriorated. When life expectancy in Slovakia is compared with the Czech Republic, its poorer outcome results from a higher cardiovascular mortality, as well as from liver, digestive and respiratory disorders. Root causes of this difference are possibly in a marked difference in funding of health care between SK and CZ, higher consumption of alcohol and cigarettes, as well as in a sizeable disadvantaged Roma minority in Slovakia.

    This paper presents findings from a collaborative inquiry project that explored teaching approaches that highlight the significance of multilingualism, multimodality, and multiliteracies in classrooms with high numbers of English language learners (ELLs). The research took place in an inner city elementary school with a large population of recently arrived and Canadian-born linguistically and culturally diverse students from Gambian, Indian, Mexican, Sri Lankan, Tibetan and Vietnamese backgrounds, as well as a recent wave of Roma students from Hungary. A high number of these students were from families with low-SES. The collaboration between two Grade 3 teachers and university-based researchers sought to create instructional approaches that would support students' academic engagement and literacy learning. In this paper, we described one of the projects that took place in this class, exploring how a descriptive writing unit could be implemented in a way that connected with students' lives and enabled them to use their home languages, through the creation of multiple texts, using creative writing, digital technologies, and drama pedagogy. This kind of multilingual and multimodal classroom practice changed the classroom dynamics and allowed the students access to identity positions of expertise, increasing their literacy investment, literacy engagement and learning.

    Iglesias, Carlos A.; Fernández-Villamor, José Ignacio; Del Pozo, David; Garulli, Luca; García, Boni

    This chapter presents the Romulus project approach to Service Development using Java-based web technologies. Romulus aims at improving productivity of service development by providing a tool-supported model to conceive Java-based web applications. This model follows a Domain Driven Design approach, which states that the primary focus of software projects should be the core domain and domain logic. Romulus proposes a tool-supported model, Roma Metaframework, that provides an abstraction layer on top of existing web frameworks and automates the application generation from the domain model. This metaframework follows an object centric approach, and complements Domain Driven Design by identifying the most common cross-cutting concerns (security, service, view, ...) of web applications. The metaframework uses annotations for enriching the domain model with these cross-cutting concerns, so-called aspects. In addition, the chapter presents the usage of mashup technology in the metaframework for service composition, using the web mashup editor MyCocktail. This approach is applied to a scenario of the Mobile Phone Service Portability case study for the development of a new service.

    We combined multi-wavelength data for blazars from the Roma-BZCAT catalog and analyzed hundreds of X-ray spectra. We present the fluxes and spectral energy distributions (SEDs), in 12 frequency bands from radio to γ-rays, for a final sample of 2214 blazars. Using a model-independent statistical approach, we looked for systematic trends in the SEDs; the most significant trends involved the radio luminosities and X-ray spectral indices of the blazars. We used a principal component analysis (PCA) to determine the basis vectors of the blazar SEDs and, in order to maximize the size of the sample, imputed missing fluxes using the K-nearest neighbors method. Using more than an order of magnitude more data than was available when Fossati et al. first reported trends of SED shape with blazar luminosity, we confirmed the anti-correlation between radio luminosity and synchrotron peak frequency, although with greater scatter than was seen in the smaller sample. The same trend can be seen between bolometric luminosity and synchrotron peak frequency. Finally, we used all of the available blazar data to determine an empirical SED description that depends only on the radio luminosity at 1.4 GHz and the redshift. We verified that this statistically significant relation was not a result of the luminosity-luminosity correlations that are natural in flux-limited samples (i.e., where the correlation is actually caused by the redshift rather than the luminosity).

  10. Kinetic Inductance Detectors development for mm-wave Astronomy

    Throughout the last decades, development of low-temperat- ure detectors focused mainly on the design of high-sensitivity, single-pixel devices. This includes such devices as semiconductor-based photodetectors and bolometers, Magnetic Metallic Calorimeters (MMC), Superconducting Tunnel Junctions (STJ), and Transition Edge Sensors (TES). However, these devices have had limited success in achieving the simultaneous large-scale array sizes and large-bandwidth operation necessary for high-speed, high-resolution detection. To overcome this performance limitation, it is advisable to focus on low-temperature detectors which are intrinsically adapted to giant-array multiplexing and ultra-fast readout. To adopt large scale frequency-domain multiplexing for low-temperature detectors, it is necessary to find detectors which"broadcast" at microwave frequencies. Superconducting microwave resonators naturally lend themselves to this task. One recent demonstration is an implementation known as Kinetic Inductance Detectors (KIDs). This detection mechanism can be adopted for low-energy EM radiation (radio, mm, THz) in continuous mode, or in pulsed mode for higher energy radiation and particles. We present an ongoing development for a KIDs instrument dedicated to millimetric ground-based observations at the 30m IRAM telescope at Pico Veleta. The Neel IRAM KIDs Array (NIKA) project is coordinated in Grenoble and involves groups in Holland (SRON), UK (Cardiff) and Italy (Roma).

    Costruito per chiara volontà del papa 70 anni dopo il caso Galileo, lo Gnomone Clementino è un grande telescopio solare che non fa uso di lenti a 92 anni dall’invenzione del cannocchiale. Queste due caratteristiche basterebbero da sole a giustificare l’interesse verso questo strumento. L’astronomia meridiana è alla base dell’astrometria e dell’astrofisica moderna. Lo Gnomone Clementino sta oggi all’astronomia, come il veliero “Amerigo Vespucci” sta alla Marina Italiana. E’ possibile svolgere ogni genere di osservazione e studio su questo strumento, e dal 2002 vi tengo lezioni teorico-pratiche del corso di Storia dell’Astronomia e La Terra nel Sistema Solare della Sapienza, Università di Roma, Facoltà di Lettere e Filosofia. Questo testo aggiunge alcuni tasselli alla ricerca storica sulla meridiana, appoggiandosi, com’è naturale, sulle spalle di giganti che mi hanno preceduto in questi studi. In particolare la misura dell’azimut della meridiana, ed il suo inquadramento tra gli strumenti simili ed alcuni studi di astrometria sui dati del 1701-1703 di Bianchini, che sono apparsi fin’ora soltanto su riviste specializzate ed in Inglese vengono qui proposti in Italiano e semplificati, per valorizzare sempre più questa straordinaria opera d’arte e di scienza.

  12. In vitro transcription profiling of the σS subunit of bacterial RNA polymerase: re-definition of the σS regulon and identification of σS-specific promoter sequence elements

    Specific promoter recognition by bacterial RNA polymerase is mediated by σ subunits, which assemble with RNA polymerase core enzyme (E) during transcription initiation. However, σ70 (the housekeeping σ subunit) and σS (an alternative σ subunit mostly active during slow growth) recognize almost identical promoter sequences, thus raising the question of how promoter selectivity is achieved in the bacterial cell. To identify novel sequence determinants for selective promoter recognition, we performed run-off/microarray (ROMA) experiments with RNA polymerase saturated either with σ70 (Eσ70) or with σS (EσS) using the whole Escherichia coli genome as DNA template. We found that Eσ70, in the absence of any additional transcription factor, preferentially transcribes genes associated with fast growth (e.g. ribosomal operons). In contrast, EσS efficiently transcribes genes involved in stress responses, secondary metabolism as well as RNAs from intergenic regions with yet-unknown function. Promoter sequence comparison suggests that, in addition to different conservation of the −35 sequence and of the UP element, selective promoter recognition by either form of RNA polymerase can be affected by the A/T content in the −10/+1 region. Indeed, site-directed mutagenesis experiments confirmed that an A/T bias in the −10/+1 region could improve promoter recognition by EσS. PMID:21398637

    The aim of this study is to assess the prevalence and risk factors of domestic violence against married women in Edirne, Turkey. This is a cross-sectional study which included a representative sample of the married women living in the Provincial Center of Edirne. The total past year prevalence of some forms of physical domestic violence is 34% in the last 12 months. 93% of women reported that they have been experiencing different forms of verbal and psychological domestic violence. The important risk factors for physical domestic violence were being Roma woman (OR = 2.97, 95% CI: 1.44-6.12), living with more than four people in the household (OR = 2.29, 95% CI: 1.21-4.36), being unemployed (OR = 2.15, 95% CI: 1.06-4.37), and got married only with her families' decision (OR = 4.60, 95% CI: 1.42-14.80). Our findings conclude that patriarchal and traditional values, women's lack of financial autonomy, and low socioeconomic status are the risk factors for physical domestic violence.

    Measles incidence declined until becomes a sporadic reporting and infrequent notification in the last decade. The reemergence of the disease reached 744 cases in 2012, a rate of 14.50×10(5) inhabitants. A classic design in Public Health Surveillance was performed: retrospective analysis of cumulative incidence and characteristics of the affected subjects. Those dates were in record linkage with Valencia Microbiology Network (RedMIVA). Finally, 976 cases of measles were confirmed in 2011-2012 epidemic period. Time-line distribution shows three waves with amplitude length on 12-15 weeks. Proportion of unvaccinated or unknown subjects came up to 85% of cases. 25 outbreaks were reported, 499 cases associated. In 7 of the 10 community outbreaks early cases were from Roma population unvaccinated. In the city of Valencia was applied post-exposure prophylaxis in 32 schools and was observed low coverage: between 63% and 77% in 8 schools and less than 50% in 4. Serum negative rate was 12.4% and we highlight the rate under 16 months: 44.8%. Cohorts of 20-59 years had negative rates between 13.5 to 5.9%. The origin of the epidemic was the importation of cases to a territory with inadequate immune protection against measles. Its impact and development was conditioned by previous immunization coverage, the social and ethnic pattern of different areas or quarters and the extensive application of post-exposure prophylaxis at school and family contacts of cases.

    Following Snyderman and Rothman (1987, 1988), we surveyed expert opinions on the current state of intelligence research. This report examines expert opinions on causes of international differences in student assessment and psychometric IQ test results. Experts were surveyed about the importance of culture, genes, education (quantity and quality), wealth, health, geography, climate, politics, modernization, sampling error, test knowledge, discrimination, test bias, and migration. The importance of these factors was evaluated for diverse countries, regions, and groups including Finland, East Asia, sub-Saharan Africa, Southern Europe, the Arabian-Muslim world, Latin America, Israel, Jews in the West, Roma (gypsies), and Muslim immigrants. Education was rated by N = 71 experts as the most important cause of international ability differences. Genes were rated as the second most relevant factor but also had the highest variability in ratings. Culture, health, wealth, modernization, and politics were the next most important factors, whereas other factors such as geography, climate, test bias, and sampling error were less important. The paper concludes with a discussion of limitations of the survey (e.g., response rates and validity of expert opinions). PMID:27047425

    An optimized use of the Grid computing resources in the ATLAS experiment requires the enforcement of a mechanism of job priorities and of resource sharing among the different activities inside the ATLAS VO. This mechanism has been implemented through the VOViews publication in the information system and the fair share implementation per UNIX group in the batch system. The VOView concept consists of publishing resource information, such as running and waiting jobs, as a function of VO groups and roles. The ATLAS Italian Cloud is composed of the CNAF Tier1 and Roma Tier2, with farms based on the LSF batch system, and the Tier2s of Frascati, Milano and Napoli based on PBS/Torque. In this paper we describe how test and deployment of the job priorities has been performed in the cloud, where the VOMS-based regional group /atlas/it has been created. We show that the VOViews are published and correctly managed by the WMS and that the resources allocated to generic VO users, users with production role and users of the /atlas/it group correspond to the defined share.

    This article describes a pilot project carried out in collaboration between the Istituto Superiore di Sanita and the Azienda Sanitaria Locale Roma E without any specific funding. The aim was to take a group of adolescents and provide them with a grounding in both HIV/AIDS infection and social communication, and with the instruments necessary to develop an informative campaign with other adolescents as the target group. The project was divided into three phases: sessions for raising levels of HIV/AIDS information and awareness involving 702 secondary school students; workshops to provide 120 selected students with communication and advertising know-how, to allow them to develop an HIV/AIDS infection information campaign targeted at their peers; a final event for the presentation of the students' findings. Prevention was the focus of the adolescents' resulting products, with particular attention to condoms as means of protection. The target population was judged as best influenced by channels such as posters and television ads, and the resulting messages were cartoon based, both ironic and fun yet accompanied by strong and direct statements designed to shock the viewer. The methods used in the project turned out to be particularly suitable for giving importance to the input of the participants who went from being publicity targets to developers.

    Summer vacations in the Dolomites were a tradition among the professors of the Faculty of Mathematical and Physical Sciences at the University of Roma since the end of the XIX century. Beyond the academic walls, people like Tullio Levi-Civita, Federigo Enriques and Ugo Amaldi sr., together with their families, were meeting friends and colleagues in Cortina, San Vito, Dobbiaco, Vigo di Fassa and Selva, enjoying trekking together with scientific discussions. The tradition was transmitted to the next generations, in particular in the first half of the XX century, and the group of via Panisperna was directly connected: Edoardo Amaldi, the son of the mathematician Ugo sr., rented at least during two summers, in 1925 and in 1949, and in the winter of 1960, a house in San Vito di Cadore, and almost every year in the Dolomites; Enrico Fermi was a frequent guest. Many important steps in modern physics, in particular the development of the Fermi-Dirac statistics and the Fermi theory of beta decay, are related to scientific discussions held in the region of the Dolomites.

The active area of a sensor is about 1 cm 2 therefore to cover the typical irradiation field used in mammography (18×24 cm 2), 18 GaAs detection units have been organized in two staggered rows of nine chips each and moved by a stepper motor in the orthogonal direction. The system is integrated in a mammographic equipment which comprehends the X-ray tube, the bias and data acquisition systems and the PC-based control system. The prototype has been developed in the framework of the Integrated Mammographic Imaging (IMI) project, an industrial research activity aiming to develop innovative instrumentation for morphologic and functional imaging. The project has been supported by the Italian Ministry of Education, University and Research (MIUR) and by five Italian High Tech companies, Alenia Marconi Systems (AMS), CAEN, Gilardoni, LABEN and Poli.Hi.Tech., in collaboration with the universities of Ferrara, Roma "La Sapienza", Pisa and the Istituto Nazionale di Fisica Nucleare (INFN). In this paper, we report on the electrical characterization and the first imaging test results of the digital mammographic system. To assess the imaging capability of such a detector we have built a phantom, which simulates the breast tissue with malignancies. The radiographs of the phantom, obtained by delivering an entrance dose of 4.8 mGy, have shown particulars with a measured contrast below 1%.

    The concept of coseismic slip and aseismic creep deformation along faults is supported by the variability of natural fault rocks and their microstructures. Faults in carbonate rocks are characterized by very narrow principal slip zones (cm to mm wide) containing (ultra)cataclastic fault rocks that accommodate most of the fault displacement. Fluidization of ultracataclastic sub layers and thermal decomposition of calcite due to frictional heating have been proposed as possible indicators for seismic slip. Dissolution-precipitation (DP) processes are possible mechanism of aseismic sliding, resulting in spaced cleavage solution planes and associated veins, indicating diffusive mass transfer and precipitation in pervasive vein networks. We investigated exhumed, sinistral strike-slip faults in carbonates of the Northern Calcareous Alps. The study presents microstructural investigations of natural carbonate fault rocks that formed by cataclastic and dissolution-precipitation related deformation processes. Faults belong to the eastern segment of the Salzachtal-Ennstal-Mariazell-Puchberg (SEMP) fault system that was formed during eastward lateral extrusion of the Eastern Alps in Oligocene to Lower Miocene. The investigated faults accommodated sinistral slip between several tens and few hundreds of meters. Microstructural analysis of fault rocks was done with scanning electron microscopy and optical microscopy. Deformation experiments of natural fault rocks are planned to be conducted at the Sapienza University of Roma and should be available at the meeting. The investigated fault rocks give record of alternating cataclastic deformation and DP creep. DP fault rocks reveal various stages of evolution including early stylolites, pervasive pressure solution seams and cleavage, localized shear zones with syn-kinematic calcite fibre growth and mixed DP/cataclastic microstructures, involving pseudo sc- and scc'-fabrics. Pressure solution seams host fine grained kaolinit, chlorite

    Salmonella serovars have been associated with the majority of foodborne illness outbreaks involving tomatoes, and E. coli O157:H7 has caused outbreaks involving other fresh produce. Contamination by both pathogens has been thought to originate from all points of the growing and distribution process. To determine if Salmonella serovar Typhimurium and E. coli O157:H7 could move to the mature tomato fruit of different tomato cultivars following contamination, three different contamination scenarios (seed, leaf, and soil) were examined. Following contamination, each cultivar appeared to respond differently to the presence of the pathogens, with most producing few fruit and having overall poor health. The Micro-Tom cultivar, however, produced relatively more fruit and E. coli O157:H7 was detected in the ripe tomatoes for both the seed- and leaf- contaminated plants, but not following soil contamination. The Roma cultivar produced fewer fruit, but was the only cultivar in which E. coli O157:H7 was detected via all three routes of contamination. Only two of the five cultivars produced tomatoes following seed-, leaf-, and soil- contamination with Salmonella Typhimurium, and no Salmonella was found in any of the tomatoes. Together these results show that different tomato cultivars respond differently to the presence of a human pathogen, and for E. coli O157:H7, in particular, tomato plants that are either contaminated as seeds or have a natural opening or a wound, that allows bacteria to enter the leaves can result in plants that have the potential to produce tomatoes that harbor internalized pathogenic bacteria.

    Introduction Gypsies, Travellers and Roma (referred to here as Travellers) experience significantly poorer health and have shorter life expectancy than the general population. They are also less likely to access health services including immunisation. To improve immunisation rates, we need to understand what helps and hinders individuals in these communities in taking up immunisations. This study has two aims: (1) Investigate the barriers and facilitators to acceptability and uptake of immunisations among six Traveller communities in the UK; (2) Identify potential interventions to increase uptake in these Traveller communities. Methods and analysis A three-phase qualitative study with six Traveller communities. PHASE 1: In each community, we will explore up to 45 Travellers’ views about the influences on their immunisation behaviours and ideas for improving uptake in their community. PHASE 2: In each community, we will investigate 6–8 service providers’ perspectives on barriers and facilitators to childhood and adult immunisations for Traveller communities with whom they work, and ideas to improve uptake. Interview data will be analysed using the Framework approach. PHASE 3: The findings will be discussed and interventions prioritised in six workshops, each with 10–12 phase 1 and 3–4 phase 2 participants. Ethics and dissemination This research received approval from NRES Committee Yorkshire and The Humber-Leeds East (Ref. 13/YH/02). It will produce (1) findings on the barriers and facilitators to uptake of immunisations in six Traveller communities; (2) a prioritised list of potentially feasible and acceptable interventions for increasing uptake in these communities; and (3) methodological development in undertaking research with diverse Traveller communities. The study has the potential to inform new ways of delivering services to ensure high immunisation uptake. Findings will be disseminated to participants, relevant UK organisations with responsibility

    In the last decade, the subject area of the survey, and also that of representation, have undergone major changes with the introduction and use of advanced technologies that have revolutionized both the operational processes dedicated to the withdrawal of the measures that those graphic display data in terms of return and performance. The three-dimensional vision deriving from direct observation, or photogrammetric instrumental with the application of images, constitutes the most complete display means of the formal, morphological and material aspects of the detected object. 3D modeling offers many advantages, such as managing even the most complex geometric surfaces and its use is investing many sectors: in particular in the field of architecture serves many purposes including documentation, representation, diagnostics, materials and degradation, the enhancement and conservation of the property, etc.. The laser scanner technology together with that of fotomodellazione, is aimed to the acquisition, modeling and rendering threedimensional (3D) surface observed physical. The laser system to scan, as well as that of photographing, provides as a direct result of the measurement session a set of three-dimensional coordinates, in a reference system linked with the instrument. The high amount of sampled data, in the order of thousands per second, allows to obtain a high level of detail offering an acquisition that could be called pseudo-continuous. In this context, there is a complex major project work on the Basilica di San Lorenzo flm in Roma, - whose first partial results have recently been published - in the course of an activity which has been carried out to study and research for the establishment of procedures for processing the most appropriate and valid to be applied during post-processing for the eventual realization of a proper three-dimensional model. This paper will illustrate, through the analysis of some significant episodes of the Basilica, as the criteria

    Rugby sevens is a rapidly growing sport. Match analysis is increasingly being used by sport scientists and coaches to improve the understanding of the physical demands of this sport. This study investigated the physical and physiological demands of elite men's rugby sevens, with special reference to the temporal patterns of fatigue during match play. Nine players, 4 backs and 5 forwards (age 25.1 ± 3.1 years) participated during 2 "Roma 7" international tournaments (2010 and 2011). All the players were at the professional level in the highest Italian rugby union, and 5 of these players also competed at the international level. During the matches (n = 15), the players were filmed to assess game performance. Global positioning system, heart rate (HR), and blood lactate (BLa) concentration data were measured and analyzed. The mean total distance covered throughout matches was 1,221 ± 118 m (first half = 643 ± 70 m and second half = 578 ± 77 m; with a decrease of 11.2%, p > 0.05, Effect Size [ES] = 0.29). The players achieved 88.3 ± 4.2 and 87.7 ± 3.4% of the HRmax during the first and second halves, respectively. The BLa for the first and second halves was 3.9 ± 0.9 and 11.2 ± 1.4 mmol·L, respectively. The decreases in performance occurred consistently in the final 3 minutes of the matches (-40.5% in the distance covered per minute). The difference found in relation to the playing position, although not statistically significant (p = 0.11), showed a large ES (η = 0.20), suggesting possible practical implications. These results demonstrate that rugby sevens is a demanding sport that places stress on both the anaerobic glycolytic and aerobic oxidative energy systems. Strength and conditioning programs designed to train these energy pathways may prevent fatigue-induced reductions in physical performance.

    Onomatopoeias (Roma Tre, Rome, 2013; algorithms: Asaga et al. in Onomatopedia, pp 601-612, 2008) has been related to onomatopoeias since Cratilo's analysis of the analogical dimension of verbal language. Nonetheless, it is still difficult to accept a (semantic, functional or grammatical) descriptive and explicative model of onomatopoeia, because the rules that constrain processes of selection and construction remain idiosyncratic and variable (Dogana in Le parole dell'incanto. FrancoAngeli, Milano, 2002; Catricalà 2011). This article proposes a classification model based on spatial cognition criteria. The hypothesis (Catricalà 2011) is that onomatopoeias are related to image schemas (Johnson in The body in the mind. University Press, Chicago, 1987), i.e. to the visual mapping of a movement. We also refer to force dynamic (Talmy in Language typology and lexical description, pp 36-149, 1985; Jackendoff in Semantic structures. MIT Press, Cambridge, 1990) as a basic model of conceptual maps (Langacker in Grammar and conceptualization. Mouton de Gruyter, Berlin, 1999). Categories are related to the presence of specific phonemes and phoneme clusters, while visual patterns correspond to different image schemas. The association between specific categories of pseudo-onomatopoeias and specific spatial/movement patterns is also the object of an experiment focused on onomatopoeia interpretation.

    The first step in the planning for a renewal of a railway network consists in gathering information, as effectively as possible, about the state of the railway tracks. Nowadays, this activity is mostly carried out by digging trenches at regular intervals along the whole network, to evaluate both geometrical and geotechnical properties of the railway track bed. This involves issues, mainly concerning the invasiveness of the operations, the impacts on the rail traffic, the high costs, and the low levels of significance concerning such discrete data set. Ground-penetrating radar (GPR) can represent a useful technique for overstepping these issues, as it can be directly mounted onto a train crossing the railway, and collect continuous information along the network. This study is aimed at defining an empirical model for the prediction of fouling in railway ballast, by using GPR. With this purpose, a thorough laboratory campaign was implemented within the facilities of Roma Tre University. In more details, a 1.47 m long × 1.47 m wide × 0.48 m height plexiglass framework, accounting for the domain of investigation, was laid over a perfect electric conductor, and filled up with several configuration of railway ballast and fouling material (clayey sand), thereby representing different levels of fouling. Then, the set of fouling configurations was surveyed with several GPR systems. In particular, a ground-coupled multi-channel radar (600 MHz and 1600 MHz center frequency antennas) and three air-launched radar systems (1000 MHz and 2000 MHz center frequency antennas) were employed for surveying the materials. By observing the results both in terms of time and frequency domains, interesting insights are highlighted and an empirical model, relating in particular the shape of the frequency spectrum of the signal and the percentage of fouling characterizing the surveyed material, is finally proposed.

    Drug treatment of functional dyspepsia is often unsatisfactory. We assessed the efficacy of a bicarbonate-sulphate-calcium thermal water cycle of 12 days, in patients with functional dyspepsia. Patients with functional dyspepsia were sent by their general practitioners to 12 days of treatment with thermal water, 200–400 ml in the morning, at temperature of 33°C (91.4 F) and were evaluated on a strict intention to treat basis. Four efficacy endpoints were analyzed as follows: (i) reduction of the global symptoms score, (ii) reduction of intensity to a level not interfering with everyday activities, (iii) specific efficacy on ulcer-like or dysmotility-like dyspepsia and (iv) esophageal or abdominal-associated symptoms. Statistical significance was reached for all three primary outcomes after the first 29 consecutive patients. Thermal water reduced the global symptom score, reduced intensity of symptoms to a level not interfering with everyday activity, but was unable to completely suppress all symptoms. A parallel effect emerged for ulcer-like and dyspepsia-like subgroups. The effect on heartburn and abdominal symptoms was not significant, suggesting a specific effect of the water on the gastric and duodenal wall. The Roma II criteria identify a natural kind of dyspepsia that improves with thermal water. Ulcer-like and dysmotility-like are not therapeutically distinguishable subgroups. Patients with dominant esophageal or abdominal symptoms should receive a different therapy. Sequential methods are very effective for the evaluation of traditional care practices and should be considered preliminary and integrative to randomized controlled trials in this context.

These computations were done on the basis of results of trajectory calculations for inclined cut-off rigidities for various azimuth and zenith angles (0°, 15°, 30°, 45°, 60°) and azimuth directions changing from 0° to 360° in steps of 45°. The information on integral multiplicities of secondary neutrons detected by neutron monitor in dependence of zenith angle of incoming primary CR particles have been also used. This information is based on the theoretical calculations of meson-nuclear cascades of primary protons with different rigidities arriving to the Earth's atmosphere at zenith angles 0°, 15°, 30°, 45°, 60° and 75°. By using this information and data of CR latitude survey from Antarctica to Italy in minimum of solar activity we determine coupling functions for NM-64 and NM without lead. Reference: L.I.

    The combined catalogue of AGN (ROSAT BSC/FSC AGN) selected from optical identifications of X-ray sources based on Hamburg--ROSAT Catalogue (HRC) and Byurakan--Hamburg--ROSAT Catalogue (BHRC) is a homogeneous sample for statistical studies. Optically identified X-ray sources from ROSAT Bright Source Catalogue (BSC) and Faint Source Catalogue (FSC) are included, 4253 X-ray selected AGN in total. All these sources are confirmed or candidate AGN based on Hamburg Quasar Survey (HQS) low-dispersion spectra. 3352 of them are listed in the Catalogue of QSOs and Active Galaxies (Véron-Cetty & Véron (2010; 13th version) and 387 are in the Multifrequency Catalogue of Blazars (Roma--BZCAT) by Massaro et al. (2012). We carried out classification for 210 of these candidate sources based on available SDSS spectra and enlarged the sample of confirmed AGN to 3650. A special emphasis is made on narrow-line Sy1.0-Sy1.5 galaxies and QSOs, as many of them have soft X-ray, strong FeII lines, and relatively narrow lines coming from BLR (“narrow broad lines”) we have classified 45 new AGN as such objects. We carried out statistical investigations of the sample, including study of luminosity function, flux-ratios for different ranges, luminosity evolution, etc. Multiwavelength SEDs have also been constructed to follow their behavior for different kinds of AGN and link these SEDs to classifications. The sample is a relevant sources for identification of new blazars.

    Minmi is the only known genus of ankylosaurian dinosaur from Australia. Seven specimens are known, all from the Lower Cretaceous of Queensland. Only two of these have been described in any detail: the holotype specimen Minmi paravertebra from the Bungil Formation near Roma, and a near complete skeleton from the Allaru Mudstone on Marathon Station near Richmond, preliminarily referred to a possible new species of Minmi. The Marathon specimen represents one of the world’s most complete ankylosaurian skeletons and the best-preserved dinosaurian fossil from eastern Gondwana. Moreover, among ankylosaurians, its skull is one of only a few in which the majority of sutures have not been obliterated by dermal ossifications or surface remodelling. Recent preparation of the Marathon specimen has revealed new details of the palate and narial regions, permitting a comprehensive description and thus providing new insights cranial osteology of a basal ankylosaurian. The skull has also undergone computed tomography, digital segmentation and 3D computer visualisation enabling the reconstruction of its nasal cavity and endocranium. The airways of the Marathon specimen are more complicated than non-ankylosaurian dinosaurs but less so than derived ankylosaurians. The cranial (brain) endocast is superficially similar to those of other ankylosaurians but is strongly divergent in many important respects. The inner ear is extremely large and unlike that of any dinosaur yet known. Based on a high number of diagnostic differences between the skull of the Marathon specimen and other ankylosaurians, we consider it prudent to assign this specimen to a new genus and species of ankylosaurian. Kunbarrasaurus ieversi gen. et sp. nov. represents the second genus of ankylosaurian from Australia and is characterised by an unusual melange of both primitive and derived characters, shedding new light on the evolution of the ankylosaurian skull.

    The detection properties of heteropitaxial (polycrystalline, pCVD) and homoepitaxial (single crystal, scCVD) diamond films grown by microwave chemical vapor deposition (CVD) in the Laboratories of Roma "Tor Vergata" University are reported. The pCVD diamond detectors were tested with α-particles from different sources and 12C ions produced by 15 MV Tandem accelerator at Southern National Laboratories (LNS) in Catania (Italy). pCVDs were also used to monitor 14 MeV neutrons produced by the D-T plasma at Joint European Torus (JET), Culham, U.K. The limit of pCVDs is the poor energy resolution. To overcome this problem, we developed scCVD diamonds using the same reactor parameters that optimized pCVD diamonds. scCVD were grown on a low cost (1 0 0) HPHT single crystal substrate. A detector 110 μm thick was tested under α-particles and under 14 MeV neutron irradiation. The charge collection efficiency spectrum measured under irradiation with a triple α-particle source shows three clearly resolved peaks, with an energy resolution of about 1.1%. The measured spectra under neutron irradiation show a well separated C(n,α0)9Be12 reaction peak with an energy spread of 0.5 MeV for 14.8 MeV neutrons and 0.3 MeV for 14.1 MeV neutrons, which are fully compatible with the energy spread of the incident neutron beams.

Lowell, USA, (6) SRC, Warsaw, Poland, (7) MPAe, Germany, (8) LPCE, Orleans, France; We study dynamics of thin current sheets over polar cusps from data of Interball-1 and Cluster. At the high-beta magnetopause current sheet width often reaches ion gyroradius scales, that leads to their Hall dynamics in the presence of local surface charges. Respective perpendicular electric fields provide the means for momentum coupling through the current sheets and are able to accelerate ions with gyroradius of the order or larger than the sheet width. At borders of large diamagnetic cavities this mechanism is able to support mass exchange and accelerate/ heat incoming magnetosheath particles. At larger scales the inhomogeneous electric fields at the current sheet borders can accelerate incident plasma downtail along magnetopause via inertial drift. It serves to move external plasma away for dynamic equilibrium supporting. Farther away from magnetopause similar nonlinear electric field wave trains, selfconsistently produced by interaction of reflected from the obstacle waves with magnetosheath fluctuations, destroy the incident flux into accelerated magnetosonic jets and decelerated Alfvenic flows and generate small-scale current sheets due to different sign of electron and ion inertial drift in the nonlinear electric field bursts. We suggest that this direct kinetic energy transformation creates current sheets with anomalous statistics of field rotation angles in the turbulent boundary layer in front of magnetopause, which have been attributed earlier to an intermittent turbulence. We compare measured spectra with a model of nonlinear system with intermittent chaotic behavior. Work was

    A hazardous gas eruption from two very close shallow boreholes occurred near the Fiumicino International Airport of Roma (Italy) from August to December 2013. The erupted gas was mostly CO2 of deep origin and gas output was high and sustained over time reaching values of nearly 20 t day- 1. After 3 months, the gas flux was still above 5 t day- 1 and was only stopped in December 2013 by long and expensive works of closure of the boreholes. The gas eruption was uncommon as being associated with the building of two mud volcanoes. This style of sustained deep CO2 eruptions contrasts with the more common short-lived eruptions of shallow biogenic methane-dominated gas pockets. In this work, we present the chronology of the event, the results of geological, geochemical, and geophysical monitoring and a numerical modeling. We propose that the August-December 2013 sustained and prolonged event does not relate to the simple degassing of a shallow, isolated pocket of gas. On the contrary, it reflects very specific conditions in a shallow reservoir (hosted in a 10 m thick gravel layer at - 40 m within the Tiber river delta deposits), related to the interplay between the total pressure and the fraction of free CO2 initially present, across very narrow value ranges around 0.59 MPa and 0.18, respectively. The coexistence of short-lived and long-lived eruptions from the same reservoir suggest that these conditions are not achieved everywhere in the gas reservoir, despite its homogeneous properties. This consideration implies either a pressure compartmentalization of the reservoir, or the occurrence of a transient, possibly associated with an impulsive release of gas from greater depths. The involvement of deeper and larger gas reservoirs connected along faults is evidenced by geophysical investigations. This conceptual model bears significant implications for gas hazard studies.

    To evaluate the genotypic variation of salt stress response in tomato, physiological analyses and a proteomic approach have been conducted in parallel on four contrasting tomato genotypes. After a 14 d period of salt stress in hydroponic conditions, the genotypes exhibited different responses in terms of plant growth, particularly root growth, foliar accumulation of Na(+), and foliar K/Na ratio. As a whole, Levovil appeared to be the most tolerant genotype while Cervil was the most sensitive one. Roma and Supermarmande exhibited intermediary behaviours. Among the 1300 protein spots reproducibly detected by two-dimensional electrophoresis, 90 exhibited significant abundance variations between samples and were submitted to mass spectrometry for identification. A common set of proteins (nine spots), up- or down-regulated by salt-stress whatever the genotype, was detected. But the impact of the tomato genotype on the proteome variations was much higher than the salt effect: 33 spots that were not variable with salt stress varied with the genotype. The remaining number of variable spots (48) exhibited combined effects of the genotype and the salt factors, putatively linked to the degrees of genotype tolerance. The carbon metabolism and energy-related proteins were mainly up-regulated by salt stress and exhibited most-tolerant versus most-sensitive abundance variations. Unexpectedly, some antioxidant and defence proteins were also down-regulated, while some proteins putatively involved in osmoprotectant synthesis and cell wall reinforcement were up-regulated by salt stress mainly in tolerant genotypes. The results showed the effect of 14 d stress on the tomato root proteome and underlined significant genotype differences, suggesting the importance of making use of genetic variability.

    Computer modeling through digital range images has been used for many applications, including 3D modeling of objects belonging to our cultural heritage. The scales involved range from small objects (e.g. pottery), to middle-sized works of art (statues, architectural decorations), up to very large structures (architectural and archaeological monuments). For any of these applications, suitable sensors and methodologies have been explored by different authors. The object to be modeled within this project is the "Plastico di Roma antica," a large plaster-of-Paris model of imperial Rome (16x17 meters) created in the last century. Its overall size therefore demands an acquisition approach typical of large structures, but it also is characterized extremely tiny details typical of small objects (houses are a few centimeters high; their doors, windows, etc. are smaller than 1 centimeter). This paper gives an account of the procedures followed for solving this "contradiction" and describes how a huge 3D model was acquired and generated by using a special metrology Laser Radar. The procedures for reorienting in a single reference system the huge point clouds obtained after each acquisition phase, thanks to the measurement of fixed redundant references, are described. The data set was split in smaller sub-areas 2 x 2 meters each for purposes of mesh editing. This subdivision was necessary owing to the huge number of points in each individual scan (50-60 millions). The final merge of the edited parts made it possible to create a single mesh. All these processes were made with software specifically designed for this project since no commercial package could be found that was suitable for managing such a large number of points. Preliminary models are presented. Finally, the significance of the project is discussed in terms of the overall project known as "Rome Reborn," of which the present acquisition is an important component.

    The change in radiative output of the Sun on time scales longer than a day is attributed to the variability in solar surface magnetic fields. Direct irradiance measurements are only available for less than four decades. To reconstruct long term trends in solar total and spectral irradiance, proxies of solar surface magnetism like sunspot, facular and network areas are needed. Currently, sunspot records alone are used for this purpose, from which the deduction of facular and network areas is rather indirect. Historical records of full disk images of the Sun taken in the Ca II K spectral line (393.3 nm) have the potential to provide far more direct information about the distribution and evolution of faculae and network elements. The latter appear as bright regions in the Ca II K spectroheliograms and their intensity is correlated with the magnetic field strength of the features on the solar surface. Solar full disk images in the Ca II K line have been recorded since the beginning of the 20th century at a number of solar observatories such as at Arcetri (Italy), Mount Wilson(California, US) and Kodaikanal (India). The images are available in digitized archives that contain the data processed for standard instrumental calibrations. To utilize these records for irradiance studies, the next step is to identify the bright magnetic features from the images using feature recognition techniques. We test different feature identification methods which are first applied to a set of recent images from the PSPT instrument at the Osservatorio Astronomico di Roma, taken during three periods characterized by high, medium and low levels of activity. Then the performance of these methods to historical images from Arcetri, Mt. Wilson and Kodaikanal archives is tested. The results will be presented and discussed here.

    The discrepancy in HIV rates among Eastern and Central European injecting drug users (IDUs) suggests that, in addition to risk behaviors, social contact patterns also play an important role. We identify two groups of IDUs in Budapest, Hungary, marginalized IDUs (M-IDUs) and socially integrated IDUs (SI-IDUs), and compare their HIV/HBV/HCV social and risk network characteristics, risk behaviors, and travel patterns. Between 05/2003 and 01/2004, 29 non-treatment-recruited young IDUs in Budapest participated in ethnographic interviews and focus groups. The mean age was 23.6 years (SD=3.6); eight were female and two Roma/Gypsy. Most injected heroin (n=23) and/or amphetamines (n=10) in the past 30 days. M-IDUs had no legal employment, injected heroin and sniffed glue, and stopped using drugs in treatment/prison. SI-IDUs had regular jobs or were students, injected heroin and sniffed cocaine, and stopped using drugs before exams/tests. Both M-IDUs and SI-IDUs shared injecting equipment on occasion and used condoms rarely. M-IDUs had a large social network of “buddies” and a small risk network of “friends”. SI-IDUs had two separate large social networks of “buddies”: a M-IDU and a non-IDU network; and a small risk network of “friends”. Both groups reported monogamous sexual relationships. M-IDUs traveled within Hungary whereas SI-IDUs traveled to Western Europe. If an HIV epidemic among IDUs in Hungary is not prevented, SI-IDUs may form a potential “bridge” of HIV infection between high-risk IDU populations and the low-risk, general population, while M-IDUs may become cores of infection. Different approaches may be appropriate for M-IDUs and SI-IDUs to prevent HIV. PMID:16107433

    Aim To evaluate Y-chromosomal diversity of the Moravian Valachs of the Czech Republic and compare them with a Czech population sample and other samples from Central and South-Eastern Europe, and to evaluate the effects of genetic isolation and sampling. Methods The first sample set of the Valachs consisted of 94 unrelated male donors from the Valach region in northeastern Czech Republic border-area. The second sample set of the Valachs consisted of 79 men who originated from 7 paternal lineages defined by surname. No close relatives were sampled. The third sample set consisted of 273 unrelated men from the whole of the Czech Republic and was used for comparison, as well as published data for other 27 populations. The total number of samples was 3244. Y-short tandem repeat (STR) markers were typed by standard methods using PowerPlex® Y System (Promega) and Yfiler® Amplification Kit (Applied Biosystems) kits. Y-chromosomal haplogroups were estimated from the haplotype information. Haplotype diversity and other intra- and inter-population statistics were computed. Results The Moravian Valachs showed a lower genetic variability of Y-STR markers than other Central European populations, resembling more to the isolated Balkan populations (Aromuns, Csango, Bulgarian, and Macedonian Roma) than the surrounding populations (Czechs, Slovaks, Poles, Saxons). We illustrated the effect of sampling on Valach paternal lineages, which includes reduction of discrimination capacity and variability inside Y-chromosomal haplogroups. Valach modal haplotype belongs to R1a haplogroup and it was not detected in the Czech population. Conclusion The Moravian Valachs display strong substructure and isolation in their Y chromosomal markers. They represent a unique Central European population model for population genetics.

    We report on the discovery of 41 new pulsating sources in the data of the Chandra Advanced CCD Imaging Spectrometer, which is sensitive to X-ray photons in the 0.3-10 keV band. The archival data of the first 15 yr of Chandra observations were retrieved and analysed by means of fast Fourier transforms, employing a peak-detection algorithm able to screen candidate signals in an automatic fashion. We carried out the search for new X-ray pulsators in light curves with more than 50 photons, for a total of about 190 000 light curves out of about 430 000 extracted. With these numbers, the ChAndra Timing Survey at Brera And Roma astronomical observatories (CATS @ BAR) - as we called the project - represents the largest ever systematic search for coherent signals in the classic X-ray band. More than 50 per cent of the signals were confirmed by further Chandra (for those sources with two or more pointings), XMM-Newton or ROSAT data. The period distribution of the new X-ray pulsators above ˜2000 s resembles that of cataclysmic variables, while there is a paucity of sources with shorter period and low fluxes. Since there is not an obvious bias against these detections, a possible interpretation is in terms of a magnetic gating mechanism in accreting neutron stars. Finally, we note that CATS @ BAR is a living project and the detection algorithm will continue to be routinely applied to the new Chandra data as they become public. Based on the results obtained so far, we expect to discover about three new pulsators every year.

    The role of dispersion or van de Waals (VDW) interactions in imidazolium-based room-temperature ionic liquids is studied within the framework of density functional theory, using a recently developed non-empirical functional [M. Dion, H. Rydberg, E. Schröder, D. C. Langreth, and B. I. Lundqvist, Phys. Rev. Lett. 92, 246401 (2004)], as efficiently implemented in the SIESTA code [G. Román-Pérez and J. M. Soler, Phys. Rev. Lett. 103, 096102 (2009)]. We present results for the equilibrium structure and lattice parameters of several crystalline phases, finding a general improvement with respect to both the local density (LDA) and the generalized gradient approximations (GGA). Similar to other systems characterized by VDW bonding, such as rare gas and benzene dimers as well as solid argon, equilibrium distances and volumes are consistently overestimated by ≈7%, compared to -11% within LDA and 11% within GGA. The intramolecular geometries are retained, while the intermolecular distances and orientations are significantly improved relative to LDA and GGA. The quality is superior to that achieved with tailor-made empirical VDW corrections ad hoc [M. G. Del Pópolo, C. Pinilla, and P. Ballone, J. Chem. Phys. 126, 144705 (2007)]. We also analyse the performance of an optimized version of this non-empirical functional, where the screening properties of the exchange have been tuned to reproduce high-level quantum chemical calculations [J. Klimes, D. Bowler, and A. Michaelides, J. Phys.: Condens. Matter 22, 074203 (2010)]. The results for solids are even better with volumes and geometries reproduced within 2% of experimental data. We provide some insight into the issue of polymorphism of [bmim][Cl] crystals, and we present results for the geometry and energetics of [bmim][Tf] and [mmim][Cl] neutral and charged clusters, which validate the use of empirical force fields.

    Salmonella serovars have been associated with the majority of foodborne illness outbreaks involving tomatoes, and E. coli O157:H7 has caused outbreaks involving other fresh produce. Contamination by both pathogens has been thought to originate from all points of the growing and distribution process. To determine if Salmonella serovar Typhimurium and E. coli O157:H7 could move to the mature tomato fruit of different tomato cultivars following contamination, three different contamination scenarios (seed, leaf, and soil) were examined. Following contamination, each cultivar appeared to respond differently to the presence of the pathogens, with most producing few fruit and having overall poor health. The Micro-Tom cultivar, however, produced relatively more fruit and E. coli O157:H7 was detected in the ripe tomatoes for both the seed- and leaf- contaminated plants, but not following soil contamination. The Roma cultivar produced fewer fruit, but was the only cultivar in which E. coli O157:H7 was detected via all three routes of contamination. Only two of the five cultivars produced tomatoes following seed-, leaf-, and soil- contamination with Salmonella Typhimurium, and no Salmonella was found in any of the tomatoes. Together these results show that different tomato cultivars respond differently to the presence of a human pathogen, and for E. coli O157:H7, in particular, tomato plants that are either contaminated as seeds or have a natural opening or a wound, that allows bacteria to enter the leaves can result in plants that have the potential to produce tomatoes that harbor internalized pathogenic bacteria.

    Dairy products are characterized by reduced shelf life because they are an excellent growth medium for a wide range of microorganisms. For this reason, it is important to monitor the microbiological quality of dairy products and, in particular, the total viable count and concentration of Escherichia coli, as they are indicators of the hygienic state of these products. In addition, in dairy products such as Mozzarella cheese, it is important to monitor the concentration of lactic acid bacteria (LAB), as they are the major components of starter cultures used in cheese production, contributing to the taste and texture of fermented products and inhibiting food spoilage bacteria by producing growth-inhibiting substances. For these reasons, to ensure the quality and safety of their products, cheese makers should monitor frequently, during fresh cheese production, the concentration of LAB and spoilage bacteria. However, usually, small- to medium-size dairy factories do not have an internal microbiological laboratory and external laboratories of analysis are often too expensive and require several days for the results. Compared with traditional methods, the microbiological survey (MBS) method developed by Roma Tre University (Rome, Italy) allows faster and less-expensive microbiological analyses to be conducted wherever they are necessary, without the need for a microbiological laboratory or any instrumentation other than MBS vials and a thermostat. In this paper, we report the primary validation of the MBS method to monitor LAB concentration in Mozzarella cheese and the analysis, using the MBS method, of total viable count, E. coli, and LAB concentrations in the production line of Mozzarella cheese as well as during the shelf life of the product stored at 20°C. The results obtained indicate that the MBS method may be successfully used by small- to medium-size dairy factories that do not have an internal microbiological laboratory. Using the MBS method, these dairy

With respect to increasing risks related to global change, the concept of ecosystem services has a capacity to contribute to safety of both, social and natural systems and vulnerability reduction. Here we study the role of the pool of ecosystem services in terms of flood mitigation and vulnerability reduction model, in a deltaic margins of the European coast (the complex land-sea system of the Waddenzee, comprising the Netherland inner coast and the islands, North Sea) then applicable to a wide variety of deltaic regions in developing areas. Extensive tidal mud flats, saltmarshes, dune ridges and sandy spits between the mainland and the chain of islands, support valuable sediment and primary production regulation along the seaside of these ecosystems. The system includes an incentive ecosystem structure (dune system) whereby economic agents would choose development activities that reduce vulnerability (flooding protection and erosion prevention) as well as satisfy production objectives (recreation and tourism). Vulnerability values extracted using remote sensing processors represent an innovative development of systems and methodologies. Using remote sensing observations, we investigate the distribution of spatial vegetation and substrate patterns controlled by changes in environmental variables acting on deltas, and we speculate the conditions under which the Real Elementary area can be defined.

L’esame duplex-ecodoppler è una metodica di largo impiego nello studio delle strutture in movimento in particolar modo a livello delle strutture del sistema vascolare. MATERIALI E METODI: È stata utilizzata un’apparecchiatura Toshiba APLIO SSA-770A, con l’uso di tecnica duplex-ecodoppler multi display, che consente la visualizzazione contemporanea dell’immagine ecografica e dei segnali Doppler utilizzando una sonda lineare del tipo phased array con cristalli trasduttori funzionanti ad una frequenza fondamentale di 6 MHz per gli spettri Doppler pulsati e 7.5 MHz per l’imaging ecografico. Sono stati esaminati nel Dipartimento di Scienze Radiologiche, Oncologiche e Anatomo-patologiche dell’Università “Sapienza” di Roma, 30 pazienti del reparto di Ortognatodonzia dell’Istituto di Odontoiatria della stessa Università. RISULTATI: Nei pazienti normali si è ottenuta un’alternanza regolare degli spettri Doppler, mentre nei soggetti con disfunzioni del complesso condilo-meniscale, si è persa la regolarità della sommatoria degli spettri di Fourier, con altezze incostanti in relazione a spostamenti irregolari del complesso condilo-meniscale. CONCLUSIONI: L’esame ecodoppler si è dimostrato, in tutti i pazienti, capace di discriminare quelli normali dai patologici e tra questi ultimi ha permesso di identificare gli aspetti più significativi delle patologie disfunzionali.

  14. GlioLab-a space system for Glioblastoma multiforme cells on orbit behavior study

    Cappelletti, Chantal; Twiggs, Robert J.

    Microgravity conditions and ionizing radiation pose significant health risks for human life in space. This is a concern for future missions and also for future space tourism flights. Nev-ertheless, at the same time it is very interesting to study the effects of these conditions in unhealthy organism like biological samples affected by cancer. It is possible that space envi-ronment increases, decreases or doesn't have any effect on cancer cells. In any case the test results give important informations about cancer treatment or space tourism flight for people affected by cancer. GlioLab is a joint project between GAUSS-Group of Astrodynamics at the "Sapienza" University of Roma and the Morehead State University (MSU) Space Science Center in Kentucky. The main goal of this project is the design and manufacturing of an autonomous space system to investigate potential effects of the space environment exposure on a human glioblastoma multiforme cell line derived from a 65-year-old male and on Normal Human Astrocytes (NHA). In particular the samples are Glioblastoma multiforme cancer cells because the radiotherapy using ionizing radiation is the only treatment after surgery that can give on ground an improvement on the survival rate for this very malignant cancer. During a mission on the ISS, GlioLab mission has to test the in orbit behavior of glioblastoma cancer cells and healthy neuronal cells, which are extremely fragile and require complex experimentation and testing. In this paper engineering solutions to design and manufacturing of an autonomous space system that can allow to keep alive these kind of cells are described. This autonomous system is characterized also by an optical device dedicated to cells behavior analysis and by microdosimeters for monitoring space radiation environment.

    The ATLAS Installation System v2 is the evolution of the original system, used since 2003. The original tool has been completely re-designed in terms of database backend and components, adding support for submission to multiple backends, including the original Workload Management Service (WMS) and the new PanDA modules. The database engine has been changed from plain MySQL to Galera/Percona and the table structure has been optimized to allow a full High-Availability (HA) solution over Wide Area Network. The servlets, running on each frontend, have been also decoupled from local settings, to allow an easy scalability of the system, including the possibility of an HA system with multiple sites. The clients can also be run in multiple copies and in different geographical locations, and take care of sending the installation and validation jobs to the target Grid or Cloud sites. Moreover, the Installation Database is used as source of parameters by the automatic agents running in CVMFS, in order to install the software and distribute it to the sites. The system is in production for ATLAS since 2013, having as main sites in HA the INFN Roma Tier 2 and the CERN Agile Infrastructure. The Light Job Submission Framework for Installation (LJSFi) v2 engine is directly interfacing with PanDA for the Job Management, the Atlas Grid Information System (AGIS) for the site parameter configurations, and CVMFS for both core components and the installation of the software itself. LJSFi2 is also able to use other plugins, and is essentially Virtual Organization (VO) agnostic, so can be directly used and extended to cope with the requirements of any Grid or Cloud enabled VO. In this work we will present the architecture, performance, status and possible evolutions to the system for the LHC Run2 and beyond.

    With a "Sunday between territory and music to 'National Institute of Geophysics and Volcanology," October 12, 2014 the headquarters of INGV Roma kicked off the activities of the second edition of the Week of Planet Earth. The laboratory of scientific outreach and museum activities together with volunteers of the National Civil Service have organized the whole day dedicated to the dissemination of earth sciences, involving adults and children. Especially for primary school children a laboratory was made involving three amusing activities all aimed at inspiring respect for the Earth: a theatrical representation called "The Fantastic 4... elements", a behavioral game and a nursery rhyme reading. The theater as a means of communication of science is an innovative and creative way to introduce children to important scientific concepts. The use of this methodology and simple language favoring the emotional involvement of the child facilitating learning. The main character is a child, chosen to facilitate the identification of the spectators with the protagonist, that through a fantastic journey discovers the importance of the four elements of our planet: earth, fire, air and water. As a second step, volunteers involved children in reading a nursery rhyme "the ABC to become a Friend of the Earth" inviting them to protect and respect the environment and its resources. Finally, the behavioral game gave indications about behaviors to adopt to safeguard the planet. Volunteers introduced a billboard divided into two colors, green to indicate the right behaviors and red for the wrong ones. Each child, after reading a card with indication on the behavior to adopt, had to decide if they were correct or not with respect to the environment safeguard. After listening to the children's answer, the volunteer gave the correct explanation about the appropriate behavior to adopt. At the end of the activities, each child received a certificate as "a friend of Planet Earth".

    This survey was designed to investigate the socio-demographic characteristics of and utilization of a Primary Heath Care Unit (PHCU) by Roma people (Turkish Gypsies), who live in the coverage area of Muradiye Primary Health Care Unit, as compared to members of the general population. This was a cross-sectional field study involving members of the Muradiye PHCU district. The study population comprised 127 Turkish gypsies resident in the region and 302 households selected by a stratified random sampling method. 889 household members were interviewed face-to-face at their home by means of a structured questionnaire. When the two sample groups were compared in terms of their social security coverage, rates of unemployment and educational levels, the situation of the Turkish Gypsies was found to be worse than that of the other members of the general population. 63% of the Gypsies applied to the PHCU because of health problems and 87% of these cases were treated successfully. Among those people making use of the PHCU services 47% evaluated them as being "satisfactory". Access to the PHCU services was found to be conditioned by educational level, being a Gypsy, the possession or not of a Green Card (available only to highly indigent people), whether or not the services were provided free of charge and the possession or not of social security coverage. Muradiye PHCU is well known and highly appreciated in its coverage area and is used by almost all of the residents. The main reason for the significant discrepancies in the level of health care obtained by the two population groups is the Gypsies' poorer economic situation. Among the Gypsies, the leading category of low rate social security coverage is the Green Card, which is granted to the very poor in order to reduce these inequalities. Unfortunately, the Green Card does not provide financial support for ambulatory care.

    How farming systems supply sufficient nitrogen (N) for high yields but with reduced N losses is a central challenge for reducing the tradeoffs often associated with N cycling in agriculture. Variability in soil organic matter and management of organic farms across an agricultural landscape may yield insights for improving N cycling and for evaluating novel indicators of N availability. We assessed yields, plant-soil N cycling, and root expression of N metabolism genes across a representative set of organic fields growing Roma-type tomatoes (Solanum lycopersicum L.) in an intensively-managed agricultural landscape in California, USA. The fields spanned a three-fold range of soil carbon (C) and N but had similar soil types, texture, and pH. Organic tomato yields ranged from 22.9 to 120.1 Mg ha-1 with a mean similar to the county average (86.1 Mg ha-1), which included mostly conventionally-grown tomatoes. Substantial variability in soil inorganic N concentrations, tomato N, and root gene expression indicated a range of possible tradeoffs between yields and potential for N losses across the fields. Fields showing evidence of tightly-coupled plant-soil N cycling, a desirable scenario in which high crop yields are supported by adequate N availability but low potential for N loss, had the highest total and labile soil C and N and received organic matter inputs with a range of N availability. In these fields, elevated expression of a key gene involved in root N assimilation, cytosolic glutamine synthetase GS1, confirmed that plant N assimilation was high even when inorganic N pools were low. Thus tightly-coupled N cycling occurred on several working organic farms. Novel combinations of N cycling indicators (i.e. inorganic N along with soil microbial activity and root gene expression for N assimilation) would support adaptive management for improved N cycling on organic as well as conventional farms, especially when plant-soil N cycling is rapid.

    Genetic studies noted that the Hungarian Y-chromosomal gene pool significantly differs from other Uralic-speaking populations. Hungarians show very limited or no presence of haplogroup N-Tat, which is frequent among other Uralic-speaking populations. We proposed that some genetic links need to be observed between the linguistically related Hungarian and Mansi populations.This is the first attempt to divide haplogroup N-Tat into subhaplogroups by testing new downstream SNP markers L708 and L1034. Sixty Northern Mansi samples were collected in Western Siberia and genotyped for Y-chromosomal haplotypes and haplogroups. We found 14 Mansi and 92 N-Tat samples from 7 populations. Comparative results showed that all N-Tat samples carried the N-L708 mutation. Some Hungarian, Sekler, and Uzbek samples were L1034 SNP positive, while all Mongolians, Buryats, Khanty, Finnish, and Roma samples yielded a negative result for this marker. Based on the above, L1034 marker seems to be a subgroup of N-Tat, which is typical for Mansi and Hungarian-speaking ethnic groups so far. Based on our time to most recent common ancestor data, the L1034 marker arose 2,500 years before present. The overall frequency of the L1034 is very low among the analyzed populations, thus it does not necessarily mean that proto-Hungarians and Mansi descend from common ancestors. It does provide, however, a limited genetic link supporting language contact. Both Hungarians and Mansi have much more complex genetic population history than the traditional tree-based linguistic model would suggest. PMID:25258186

    We report the results of our exploratory program carried out with the southern Astrophysical Research telescope aimed at associating counterparts and establishing the nature of the Fermi Unidentified γ-ray Sources (UGSs). We selected the optical counterparts of six UGSs from the Fermi catalog on the basis of our recently discovered tight connection between infrared and γ-ray emission found for the γ-ray blazars detected by the Wide-Field Infrared Survey Explorer in its all-sky survey. We perform for the first time a spectroscopic study of the low-energy counterparts of the Fermi UGSs, in the optical band, confirming the blazar-like nature of the whole sample. We also present new spectroscopic observations of six active galaxies of uncertain type associated with Fermi sources which appear to be BL Lac objects. Finally, we report the spectra collected for six known γ-ray blazars belonging to the Roma BZCAT that were obtained to establish their nature or better estimate their redshifts. Two interesting cases of high redshift and extremely luminous BL Lac objects (z ≥ 1.18 and z ≥ 1.02, based on the detection of Mg ii intervening systems) are also discussed. Based on observations obtained at the southern Astrophysical Research (SOAR) telescope, which is a joint project of the Ministério da Ciência, Tecnologia, e Inovação (MCTI) da República Federativa do Brasil, the U.S. National Optical Astronomy Observatory (NOAO), the University of North Carolina at Chapel Hill (UNC), and Michigan State University (MSU).

    The International Conferences on Calorimetry in High Energy Physics (also known as the Calor Conference series, started in October 1990 at Fermilab) address all aspects of calorimetric particle detection and measurement, with an emphasis on high energy physics experiments. The XIV International Conference on Calorimetry in High Energy Physics (Calor 2010) was held at the campus of the Institute of High Energy Physics, Beijing, China, from May 10-14, 2010. This conference brought together more than 110 participants from 20 countries, including senior scientists and young physicists. During the five days of the conference, 98 presentations were given in seven plenary sessions. The attendees had in-depth discussions on the latest developments and innovations in calorimetry, including the exciting new LHC results. From the presentations, 83 papers were published in this proceedings. The success of the conference was due to the participants' enthusiasm and the excellent talks given by the speakers, and to the conveners for organizing the individual sessions. We would like to thank the International Advisory Committee for giving us the opportunity to host this Conference in Beijing. Finally we would like to thank all the people involved in the organization of the Conference, who have provided valuable local support.

    The studied shallow marine sediments are situated south and southwest of Jiroft town, 180 km south of Keman, from the Tihoiyeh section (near Tihoiyeh village). These deposits at the top of the section include marly limestones with index Nummulites species such as N. perforatus (De Montfort), N. lyelli (D'Archiac and Haime). According to Schaub's nummulitic time scale (1981) and shallow benthic zonation of Serra-Kiel et al. (1998), this interval referred to Bartonian age and SBZ17 zone, respectively. Also, the calcareous nannofossil study on this interval led to identification of 19 well-preserved species belonging to 11 genera of this plankton group. Based on determined index calcareous nannofossiltaxa such as Reticulofenestra bisecta, Sphenolithus obtusus, Sphenolithus intercalaris, Cribrocentrum erbae and associated species such as Sphenolithus pseudoradians, Reticulofenestra wadeae, Cribrocentrum reticulatum and Blackites spinosus this interval assigned to the CNE15 zone of Agnini et al. (2014) that corresponds to upper part of NP16 and lower part of NP17 zones of Martini (1971). It is resulted that, the detected shallow benthic foraminifera zone, corresponds to the calcareous nannofossil zones both indicating Bartonian age.

The onset of reconnection first became apparent in the SDO/AIA images when filament plasma, originally contained within the erupting flux rope, was re-directed towards remote areas in the neighboring AR, tracing the change of large-scale magnetic connectivity. The observations are presented jointly with a topological analysis of the pre-eruption magnetic configuration, and a data-constrained numerical simulation of the three-AR complex, demonstrating the formation/intensification of current sheets along a pre-existing hyperbolic flux tube (HFT) at the interface between the CME and the neighboring AR, where a secondary flare ribbon was created. Reconnection across this current sheet resulted in the formation of new magnetic connections between the erupting magnetic structure and a neighboring AR about 200 Mm from the eruption site, in strong qualitative agreement with the observations. In addition, the CME temporarily created unusually dense plasma conditions around a reconnection region at high coronal altitudes, enabling us to observe emission resulting from it. We argue that this exceptional observation of a coronal brightening was directly observable at SDO/AIA wavelengths owing to the

    The animal and plant biodiversity of the Italian territory is known to be one of the richest in the Mediterranean basin and Europe as a whole, but does the genetic diversity of extant human populations show a comparable pattern? According to a number of studies, the genetic structure of Italian populations retains the signatures of complex peopling processes which took place from the Paleolithic to modern era. Although the observed patterns highlight a remarkable degree of genetic heterogeneity, they do not, however, take into account an important source of variation. In fact, Italy is home to numerous ethnolinguistic minorities which have yet to be studied systematically. Due to their difference in geographical origin and demographic history, such groups not only signal the cultural and social diversity of our country, but they are also potential contributors to its bio-anthropological heterogeneity. To fill this gap, research groups from four Italian Universities (Bologna, Cagliari, Pisa and Roma Sapienza) started a collaborative study in 2007, which was funded by the Italian Ministry of Education, University and Research and received partial support by the Istituto Italiano di Antropologia. In this paper, we present an account of the results obtained in the course of this initiative. Four case-studies relative to linguistic minorities from the Eastern Alps, Sardinia, Apennines and Southern Italy are first described and discussed, focusing on their micro-evolutionary and anthropological implications. Thereafter, we present the results of a systematic analysis of the relations between linguistic, geographic and genetic isolation. Integrating the data obtained in the course of the long-term study with literature and unpublished results on Italian populations, we show that a combination of linguistic and geographic factors is probably responsible for the presence of the most robust signatures of genetic isolation. Finally, we evaluate the magnitude of the diversity

    The Beatrice Gold Belt, located 65 km south of Harare, lies astride the Mupfure River, a tributary of the Sanyati River, Zambezi Basin. The belt has been mined for gold since 1900, but was abandoned towards the year 2000. The Mupfure River provides water for commercial agriculture in the local farming areas and smallholder farming in Mhondoro Communal Lands, as well as other users downstream in Chegutu and Kadoma Districts. There were four mines in the belt: Beatrice, Joyce, Argyle and Roma. They are all closed, and rehabilitation has only taken place at Beatrice mine. Each mine is located under 5 km from the Mupfure River, and so run-off from the mines and their dumps can easily reach the main river system. The dominant sulphides are arsenopyrite (FeAsS), pyrite (FeS 2), galena (PbS) and stibnite (Sb 2S 3). Gold is generally locked up in sulphides or occurs in close contact to the sulphides, so processing is associated with release of acid, arsenic and metals into streams that flow into the Mupfure River. This study was thus carried out to assess the potential impact of these abandoned mines on the water quality of the Mupfure river and its tributaries. Water samples were collected along the tributaries that drain the mining area, as well as from the mine-shafts. Parameters tested include pH, iron, copper, nickel, lead, zinc, antimony, and arsenic. Chemical results obtained show that the surface water is slightly contaminated with respect to Pb, Zn and Ni. Such contamination is attributed to the mine dumps. However, the near-neutral pH and only slight contamination show that the impact on water quality of the Beatrice mines is largely localised probably due to likely low run-off volumes from the mining sites compared to the rest of the catchment. The slight contamination could also indicate that acid mine drainage is proceeding at a slow rate or the fact that it is in its initial stages. Long term environmental management should therefore focus on controlling the

    interaction distance and are consumed faster with slip than larger ones. However, in faults, production of cataclasites and pseudotachylytes changes the contact area of sliding surfaces by interposing a layer of wear products. This layer may preserve from wearing asperities that are smaller in amplitude than the layer thickness, thus providing a mechanism that is likely to preserve small amplitude/wavelength roughness. These processes have been considered in a new spectral model of wear, which allows to model wear for self-affine surfaces and includes the accumulation of wear products within the fault zone. This model can be used to generalize our results and contribute to reconstruct a realistic model of a seismogenic fault zone (http://roma1.rm.ingv.it/laboratori/laboratorio-hp-ht/usems-project).

    Although the act of dehumanizing an outgroup is a pervasive and potent intergroup process that drives discrimination and conflict, no formal research has examined the consequences of being dehumanized by an outgroup-that is, "metadehumanization." Across 10 studies (N = 3,440) involving several real-world conflicts spanning 3 continents, we provide the first empirical evidence that metadehumanization (a) plays a central role in outgroup aggression that is (b) mediated by outgroup dehumanization, and (c) distinct from metaprejudice. Studies 1a and 1b demonstrate experimentally that Americans who learn that Arabs (Study 1a) or Muslims (Study 1b) blatantly dehumanize Americans are more likely to dehumanize that outgroup in return; by contrast, experimentally increasing outgroup dehumanization did not increase metadehumanization (Study 1c). Using correlational data, Study 2 documents indirect effects of metadehumanization on Americans' support for aggressive policies toward Arabs (e.g., torture) via Arab dehumanization. In the context of Hungarians and ethnic minority Roma, Study 3 shows that the pathway for Hungarians from metadehumanization to aggression through outgroup dehumanization holds controlling for outgroup prejudice. Study 4 examines Israelis' metaperceptions with respect to Palestinians, showing that: (a) feeling dehumanized (i.e., metadehumanization) is distinct from feeling disliked (i.e., metaprejudice), and (b) metadehumanization uniquely influences aggression through outgroup dehumanization, controlling for metaprejudice. Studies 5a and 5b explore Americans' metaperceptions regarding ISIS and Iran. We document a dehumanization-specific pathway from metadehumanization to aggressive attitudes and behavior that is distinct from the path from metaprejudice through prejudice to aggression. In Study 6, American participants learning that Muslims humanize Americans (i.e., metahumanization) humanize Muslims in turn. Finally, Study 7 experimentally contrasts

    We assess how differences in the composition of exoplanet host stars might affect the availability of water in their systems, particularly the role of carbon and oxygen abundances. Water, one of the key chemical ingredients for habitability, may be in short supply in carbon-rich, oxygen-poor systems even if planets exist in the ‘habitable zone’. For the solar system, C/O = 0.55 is particularly important in determining the refractory (silicate and metal) to volatile ice ratio expected in material condensed beyond the snow line (Gaidos E. J. Icarus 145, 637, 2000; Wong M. H. et al. in Oxygen in the Solar System, G.J. MacPherson, Ed., 2008). Our analysis of published compositions for a set of exoplanet host stars (Johnson T. V. et al. ApJ. 757(2), 192, 2012) showed that the amount of condensed water ice in those systems might range from as much as 50% by mass for sub-solar C/O = 0.35 to less than a few percent for super-solar C/O = 0.7. A recent analysis using similar techniques (Pekmezci G. S., Dottorato di Ricerca in Astronomia, Università Degli Studi di Roma “Tor Vergata”, 2014) of a much larger stellar composition data set for 974 FGK stars (Petigura E. and Marcy G. Journal of Astrophysics 735, 2011), allows us to assess the possible range of water ice abundance in the circumstellar accretion disks of these ‘solar-type’ stars (of which 72 were known to have one or more planets as of 2011). Stellar C/O in a subset (457 stars) of this stellar database with reported C, O, Ni, and Fe abundances ranges from 0.3 to 1.4. The resulting computed water ice fractions and refractory (silicate + metal) fractions range from ~0 to 0.6 and 0.3 to 0.9 respectively. These results have implications for assessing the habitability of exoplanets since they constrain the amount of water available beyond the snow line for dynamical delivery to inner planets, depending on the host stars’ C/O in the circumstellar nebula.

    For the last fifteen years the Faculty of Architecture at the University of Roma Tre, has been working on the famous Villa Adriana in Tivoli, studying its ruins and its ancient paths, in order to better understand how the villa was originally laid out. In this paper, we will talk about one of these studies, which reconnect previous works and creates a new GIS based map of Villa Adriana. The goal of this study is to create a cultural heritage evaluation. In order to achieve this aim, we have created a multimedia guide with text, drawings, 3D reconstructions and augmented reality. This work can be summarized in five steps; first of all, a new georeferenced plan was created. This drawing is based on an orthophoto and brings together all existing surveys (from historical drawings to recent surveys). In this new work we show the current status of the ruins and the original layout of Villa Adriana according to the most recent study. The second step was a 3D survey, with extensive use of photogrammetry to verify and upgrade drawings. The next and third step involved creating the Database, within which to store, edit, analyze, share, and display linked data relating to both ancient and contemporary buildings and pathways. This GIS is based on the new plan and gathers together different orders of information: original function, paving, the old paths of each original user (Hadrian, his wife Sabina, the retinue, guests and servants) as well as the ancient system of underground tunnels. It collects all the existing data relating to Villa Adriana relevant to solving the "what/where" question. The fourth step was to create a complete 3D model of Villa Adriana. The 3D reconstruction started from the existing surveys, the documentation of recent excavation and the input of the hypothetical reconstruction of lost or buried buildings. Finally we created a multimedia guide, based on a mobile app, which took information from the database to show, in real time, during the tour, where

  13. Swift: 10 Years of Discovery

    NASA Astrophysics Data System (ADS)

    The conference Swift: 10 years of discovery was held in Roma at La Sapienza University on Dec. 2-5 2014 to celebrate 10 years of Swift successes. Thanks to a large attendance and a lively program, it provided the opportunity to review recent advances of our knowledge of the high-energy transient Universe both from the observational and theoretical sides. When Swift was launched on November 20, 2004, its prime objective was to chase Gamma-Ray Bursts and deepen our knowledge of these cosmic explosions. And so it did, unveiling the secrets of long and short GRBs. However, its multi-wavelength instrumentation and fast scheduling capabilities made it the most versatile mission ever flown. Besides GRBs, Swift has observed, and contributed to our understanding of, an impressive variety of targets including AGNs, supernovae, pulsars, microquasars, novae, variable stars, comets, and much more. Swift is continuously discovering rare and surprising events distributed over a wide range of redshifts, out to the most distant transient objects in the Universe. Such a trove of discoveries has been addressed during the conference with sessions dedicated to each class of events. Indeed, the conference in Rome was a spectacular celebration of the Swift 10th anniversary. It included sessions on all types of transient and steady sources. Top scientists from around the world gave invited and contributed talks. There was a large poster session, sumptuous lunches, news interviews and a glorious banquet with officials attending from INAF and ASI. All the presentations, as well as several conference pictures, can be found in the conference website (http://www.brera.inaf.it/Swift10/Welcome.html). These proceedings have been collected owing to the efforts of Paolo D’Avanzo who has followed each paper from submission to final acceptance. Our warmest thanks to Paolo for all his work. The Conference has been made possible by the support from La Sapienza University as well as from the ARAP

    These Proceedings contain the invited and contributed papers presented at the 12th Conference on Theoretical Nuclear Physics in Italy held in Cortona, Italy, from 8-10 October 2008. As usual, the meeting was held at il Palazzone, a 16th century castle owned by the Scuola Normale Superiore di Pisa. The aim of this biennal conference is to bring together Italian theorists working in various fields of Nuclear Physics to discuss their latest results and confront their points of view in a lively and informal way. This offers the opportunity to promote collaborations between different groups. There were about 50 participants at the conference, coming from 14 Italian Universities (Cagliari, Catania, Ferrara, Firenze, Genova, Lecce, Milano, Napoli, Padova, Pavia, Pisa, Roma, Trento, Trieste). The program of the conference, prepared by the Organizing Committee (Ignazio Bombaci, Aldo Covello, Laura Elisa Marcucci and Sergio Rosati) focused on six main topics: Few-Nucleon Systems, Nuclear Matter and Nuclear Dynamics, Nuclear Astrophysics, Structure of Hadrons and Hadronic Matter, Nuclear Structure, Nuclear Physics with Electroweak Probes. Winfried Leidemann, Maria Colonna, Marcello Lissia, Elena Santopinto, Silvia Lenzi and Omar Benhar took the burden of giving general talks on these topics and reviewing the research activities of the various Italian groups. In addition, 19 contributed papers were presented, most of them by young participants. In the last session of the Conference there were two invited talks related to experimental activities of great current interest. Gianfranco Prete from the Laboratori Nazionali di Legnaro spoke about the Italian radioactive ion beam facility SPES and the status of the European project EURISOL, while Nicola Colonna from the INFN, Bari, gave an overview of the perspectives of development of fourth-generation nuclear reactors. We would like to thank the authors of the general reports for their hard work in reviewing the main achievements in

    The sustained convergence between India and Asia with successive stages of oceanic subduction, continental subduction and continental collision has lead to the formation of the Tibetan plateau while the Himalayan orogenic front acquired an arcuate shape convex toward the South. The Indian plate is bounded by north-south strike-slip faults, which accommodate a large indentation of Asia, between two oceanic subductions, beneath Makran to the west, beneath Indonesia to the east. Two syntaxes formed at both east and west termination of the Himalayan orogenic front at the transition between Indian and Asian plates. In order to better understand this particular configuration, we performed analog experiments at the Laboratory of Experimental Tectonics of Roma TRE to simulate, at the scale of the mantle - lithosphere system, the mechanics of the indentation process. The configuration is set to drive the India indenter towards the Asian continent with a motor-controlled-piston, to simulate far field stresses necessary for indentation. In particular, we test (1) which geometry and rheological parameters favor arcuate orogen and syntaxes formation, (2) what are the consequences on the topography of both the orogenic front and the plateau, and (3) how they relate with the subduction/collision dynamics. The setup is composed of a subducting and an overriding plate made of visco-elastic silicone putty, floating on low-viscosity syrup simulating the asthenosphere. The subducting plate simulates an oceanic lithosphere followed by a continental indenter (analog for the Indian craton) flanked or not by oceans (analog for Makran and Indonesian domains), while the upper continental plate simulates the Tibetan plateau. Results show that the curvature of the orogen and syntaxes' formation are primarily controlled by the strength and gravitational potential energy of the upper plate, and the shape of the subducting plate. A relatively strong upper plate flanked by oceans leads to a

On April 23-24, 1998 Interball & Polar over cusp and Geotail at the tail flank (GSM Z =10 Re) traced boundary layers (BL). The time-depended MHD modeling serves to unite the 6-point data with the global reconnection pattern, driven by strong solar wind (SW) disturbances. At the smaller scales the BL perturbations display similar kinked magnetic spectra and 3-wave phase coupling, the correlation length is less than the distance between Interball-Polar (3 RE). Strong SW disturbances, decelerated over cusp, penetrate deep into tail. For quiet SW local perturbations dominate at frequencies over few mHz. Similar spectral features are seen on June 19, 1998 both in stagnant MSH (Polar) and upstream 'plasma ball' (PB, Interball-1) - demagnetized heated plasma (ion beta ~ 2-15) of MSH origin inside MP. Comparison with SW magnetic spectra and plasma moments from Geotail using Gas Dynamic Convection Field model indicates that the patchy reconnection pulses at Polar location are modulated by the upstream BL fluctuations. The fluctuations result from direct interaction of PB with MSH flow by means of reflected from

    The Rosetta spacecraft flew by asteroid 2867 Steins in September 2008, collecting images, UV, visible and IR spectra and radar reflections. A flyby of the ˜95 km diameter asteroid 21 Lutetia is scheduled for July, 2010. Laboratory studies using meteoritic and terrestrial samples are designed to support interpretation of the observations of the asteroid targets. The goal is to study likely meteoritic analogues of Steins and Lutetia in several laboratories using the same samples in multiple experiments simulating the conditions and types of measurements made during the flybys. The first sample, 5g of an aubrite, ALHA78113,82, is an achondrite consisting of very low iron, high magnesium silicates, with small amounts of metallic and sulfide grains that may be a fragment from Steins. Chips and powdered samples have been measured in reflectance at Brown University, RELAB. Spectral imaging in visible, at INAF, Roma, was conducted on a chip before it was powdered. The spectrum has high albedo (20-40%) depending on grain size and abundance of opaque minerals. It also has an ultraviolet absorption band with two slopes and no 1- nor 2-μm bands. There is no absorption at 0.5 μm as there is in telescopic spectra of Steins. There are two separate questions related to aubrites and Steins. First, what is the nature of the absorption band first measured in the sample of ALH78113,101 at 0.42 μm? And quite separately, what is the spectroscopically active feature in the ground-based spectrum and OSIRIS photometry of Steins at 0.50 μm? Polarization and phase functions have been measured by PROGRA2-vis and -surf covering 6-150° at two wavelengths. Very small phase angle measurements are planned at Kharkiv, and ultraviolet spectra will be measured at Southwest Research Institute, Boulder along with olivine, enstatite, troilite (FeS) and Fe0. Plans are developing to measure the dielectric constant and magnetic susceptibility of the sample. Irradiated samples simulating space

    Although the act of dehumanizing an outgroup is a pervasive and potent intergroup process that drives discrimination and conflict, no formal research has examined the consequences of being dehumanized by an outgroup-that is, "metadehumanization." Across 10 studies (N = 3,440) involving several real-world conflicts spanning 3 continents, we provide the first empirical evidence that metadehumanization (a) plays a central role in outgroup aggression that is (b) mediated by outgroup dehumanization, and (c) distinct from metaprejudice. Studies 1a and 1b demonstrate experimentally that Americans who learn that Arabs (Study 1a) or Muslims (Study 1b) blatantly dehumanize Americans are more likely to dehumanize that outgroup in return; by contrast, experimentally increasing outgroup dehumanization did not increase metadehumanization (Study 1c). Using correlational data, Study 2 documents indirect effects of metadehumanization on Americans' support for aggressive policies toward Arabs (e.g., torture) via Arab dehumanization. In the context of Hungarians and ethnic minority Roma, Study 3 shows that the pathway for Hungarians from metadehumanization to aggression through outgroup dehumanization holds controlling for outgroup prejudice. Study 4 examines Israelis' metaperceptions with respect to Palestinians, showing that: (a) feeling dehumanized (i.e., metadehumanization) is distinct from feeling disliked (i.e., metaprejudice), and (b) metadehumanization uniquely influences aggression through outgroup dehumanization, controlling for metaprejudice. Studies 5a and 5b explore Americans' metaperceptions regarding ISIS and Iran. We document a dehumanization-specific pathway from metadehumanization to aggressive attitudes and behavior that is distinct from the path from metaprejudice through prejudice to aggression.

    How farming systems supply sufficient nitrogen (N) for high yields but with reduced N losses is a central challenge for reducing the tradeoffs often associated with N cycling in agriculture. Variability in soil organic matter and management of organic farms across an agricultural landscape may yield insights for improving N cycling and for evaluating novel indicators of N availability. We assessed yields, plant-soil N cycling, and root expression of N metabolism genes across a representative set of organic fields growing Roma-type tomatoes (Solanum lycopersicum L.) in an intensively-managed agricultural landscape in California, USA. The fields spanned a three-fold range of soil carbon (C) and N but had similar soil types, texture, and pH. Organic tomato yields ranged from 22.9 to 120.1 Mg ha-1 with a mean similar to the county average (86.1 Mg ha-1), which included mostly conventionally-grown tomatoes. Substantial variability in soil inorganic N concentrations, tomato N, and root gene expression indicated a range of possible tradeoffs between yields and potential for N losses across the fields. Fields showing evidence of tightly-coupled plant-soil N cycling, a desirable scenario in which high crop yields are supported by adequate N availability but low potential for N loss, had the highest total and labile soil C and N and received organic matter inputs with a range of N availability. In these fields, elevated expression of a key gene involved in root N assimilation, cytosolic glutamine synthetase GS1, confirmed that plant N assimilation was high even when inorganic N pools were low. Thus tightly-coupled N cycling occurred on several working organic farms. Novel combinations of N cycling indicators (i.e. inorganic N along with soil microbial activity and root gene expression for N assimilation) would support adaptive management for improved N cycling on organic as well as conventional farms, especially when plant-soil N cycling is rapid.

  20. Anatomy of a volcanic district in a carbonate fold-and-thrust belt: the northern Volsci Range (Italy)

    2015-04-01

    The Volsci Range is a carbonate fold-and-thrust belt crossed by important normal faults in places associated with explosive volcanic deposits and hydrothermal ongoing activity within a moderately active seismic area (e.g., Latina earthquake 2012, Mw=3.8). Though distribution of volcanites is known, origin, volume and field characterization of a previously unstudied volcanic district is far to be addressed and it is the topic of this work. Several monogenic phreatomagmatic vents occur at the edges of the chain and within its backbone. The most relevant ones are characterized at the base by well welded to zeolitized tuffs, followed either by incoherent tuffs or by surges (e.g., Patrica, Valvisciolo) and locally by lavas (i.e., Giuliano di Roma, Pofi, Terracina) and finally by late Quaternary slope deposits. Most explosive units are largely composed by local Mesozoic platform carbonate litic clasts, showing different degrees of rounding and decarbonation. Micropalaeontology and facies analysis confirm that clasts are not older than late Jurassic and not younger than Cenomanian (Upper part of the Ostracoda and Miliolidae biozone). Therefore considering the stratigraphy beneath the vent points, litics could come from depths of about 400-600 meters. Juvenile litics of different composition, accretionary lapilli and the above mention carbonate litic clasts testify for a complex conduct composition and for the rupture of the carbonatic aquifer during eruption. Right at the southern slope of the Lepini Mounts (northern Volsci Range), as detected from the analysis of the n-2 residual gravity anomalies, monogenic circular vents (tuff rings) occur buried under Quaternary deposits or are just barely cropping out as necks (Doganella di Ninfa). Further south, despite the occurrence of pyroclastic deposits in boreholes, thickness and shape of volcanic deposits below the Pontina Plain is still unconstrained, providing a challenge for further geophysical studies. However, the

    The high resolution P-wave tomography of the Italian Peninsula and surrounding regions from crustal to upper mantle depths is the aim of a joint project between INGV (Roma) and ETH (Zurich). The project is subdivided into two steps, first of which is to establish a 3D P-wave velocity model for the crust, using both passive and active seismic sources. Getting a reliable high resolution model is of fundamental importance since the 3D crustal model will be used in the second step to correct teleseismic travel times following a method successfully applied in the last years to the Alps (Waldhauser et al. 2002). In the present work we focus on the passive sources dataset (local and regional events) to complement the CSS crustal information. Our keywords being "high-resolution" and "detailed model" we followed the idea, based on the experience of previous works in this area, that a large number of high quality pickings and a high level of consistency in the dataset represent the first goals. The Italian region (Western Mediterranean) is characterized by a high rate of seismicity including important seismic sequences. Since 1988, digital recordings for about 40,000 local and regional earthquakes are available, which INGV bulletin readings have been used in previous local earthquake tomography works. To increase the sampling power and to better locate some border events we will integrate Italian National Seismic Network data with recordings from other local and regional networks. Due to the large amount of data thus collected, a manual re-picking of all first arrivals would ask for a too long time while it would not prevent from human readings errors and inconsistencies. This would partially contrast the positive effect of a high-quality pickings. To meet the quality and consistency requests, we applied an advanced automatic re-picking procedure, the MannekenPick (MP), recently developed by F. Aldersons as a fast, reliable and "consistent" picker. We tested the whole

    Climatic conditions over the last 2.7 kyr are reconstructed in base to six speleothems from a cave in Mallorca and a group of sediment cores from the Menorca Rise. Speleothem records provide a solid chronology in base to high resolution U/Th dating. Both δ 13C and particularly δ 18O records show pronounced oscillations related to pre-roman times as the Dark Middle Ages, the Medieval Climate Anomaly and the Little Ice Age. The geochemical proxies from the six studied speleothems have been stacked in a unique record, which provides decadal-multidecadal resolution. In parallel, Sea Surface Temperature (SST) conditions have been reconstructed in base to Globigerina bulloides-Mg/Ca ratios from a group of multicore records, and they have been combined with δ18O data to reconstruct changes in the evaporation-precipitation ratio of the basin. These records have also been stacked in a single anomaly curve after the accurate construction of robust multi-proxy chronologies (Cisneros et al., under evaluation). The comparison of the marine and speleothem records reveal the occurrence of synchronous changes in both SST and humidity conditions over land along the last 2.7 kyr, although the relationship of these two climatic variables changed along the different climatic events. These results support that the driest conditions occurred during part of the Roma Classic Period and also during the Medieval Climate Anomaly when climate conditions were mostly warm, but also during the second part of the Little Ice Age when cold conditions dominated. This combined land-sea proxy approach offers a powerful tool to reconstruct past climate variability with highly precise chronologies. REFERENCES: M. Cisneros, I. Cacho, J. Frigola, M. Canals, P.

    The development of close-range photogrammetry has produced a lot of new possibility to study cultural heritage. 3D data acquired with conventional and low cost cameras can be used to document, investigate the full appearance, materials and conservation status, to help the restoration process and identify intervention priorities. At the same time, with 3D survey a lot of three-dimensional data are collected and analyzed by researchers, but there are a very few possibility of 3D output. The augmented reality is one of this possible output with a very low cost technology but a very interesting result. Using simple mobile technology (for iPad and Android Tablets) and shareware software (in the case presented "Augment") it is possible to share and visualize a large number of 3D models with your own device. The case study presented is a part of an architecture graduate thesis, made in Rome at Department of Architecture of Roma Tre University. We have developed a photogrammetric survey to study the Aurelian Wall at Castra Praetoria in Rome. The surveys of 8000 square meters of surface have allowed to identify stratigraphy and construction phases of a complex portion of Aurelian Wall, specially about the Northern door of Castra. During this study, the data coming out of 3D survey (photogrammetric and topographic), are stored and used to create a reverse 3D model, or virtual reconstruction, of the Northern door of Castra. This virtual reconstruction shows the door in the Tiberian period, nowadays it's totally hidden by a curtain wall but, little and significative architectural details allow to know its original feature. The 3D model of the ancient walls has been mapped with the exact type of bricks and mortar, oriented and scaled according to the existing one to use augmented reality. Finally, two kind of application have been developed, one on site, were you can see superimposed the virtual reconstruction on the existing walls using the image recognition. On the other hand

    AIM: To investigate the pattern of symptoms, predominant bowel habits and quality of life (QOL) by the Chinese version of the SF-36 in irritable bowel syndrome (IBS) consulters in Zhejiang province. METHODS: From January 2001 to January 2002, 662 Roma II criteria- positive IBS patients were enrolled by gastroenterologists in 10 hospitals from Digestive Disease Center of Zhejiang (DDCZ). Patients were classified into constipation predominant IBS (IBS-C), diarrhea predominant IBS (IBS-D) and alternating constipation and diarrhea IBS (IBS-A) according to the predominant bowel habits. All patients were evaluated for the demographic checklists, IBS bowel symptoms, extra-colonic symptoms, and QOL by Chinese version of the SF-36 questionnaire. RESULTS: (1) Besides abdominal pain, the predominant colonic symptoms were in order of altered stool form, abnormalities of stool passage, abdominal distension and passage of mucus in IBS patients. Also, IBS subjects reported generalized body discomfort and psychosocial problems including dyspeptic symptoms, poor appetite, heartburn, headache, back pain, difficulty with urination, fatigue, anxiety and depression. (2) IBS-C and IBS-A are more common among female patients, whereas male patients experienced more cases of IBS-D. In regards to the IBS symptoms, there were significant differences among IBS subgroups. Abdominal pain (frequency ≥ 2 days per week and duration ≥ 1 hour per day) was frequent in IBS-A patients (P = 0.010 and 0.027, respectively), IBS-D patients more frequently experienced the passage of mucus, dyspeptic symptoms and anxiety (P = 0.000, 0.014 and 0.015, respectively). (3) IBS patients experienced significant impairment in QOL, decrements in QOL were most pronounced in vitality, general health, mental health, and bodily pain. Compared with the general population (adjusted for gender and age), IBS patients scored significantly lower on all SF-scales (P < 0.001), except for physical function scale (P = 0

    The polygenetic Albano maar is the most recent centre of the Colli Albani volcano, located just few kilometres to the south-east of Roma. Presently the maar hosts a 167.5 m deep crater lake, the deepest in Europe. The maar is to be considered quiescent, as phreatic activity is documented throughout the Holocene. This paper illustrates the close relationships between the activity of the maar and the history of settlement in the Roman region as recorded in the geology, archaeology, history and legends of the area. Severe fluctuations of the groundwater table and catastrophic overflows of the Lake Albano from the maar rim had occurred prior to and after the early prehistoric settlements dated in the maar area at the Eneolithic times (ca. III millennium B.C.). Repeated lahars occurred along the northwestern slope of the maar filling in the paleodrainage network and forming a vast plain. Paleohydraulic analyses on fluvial and lahar deposits originated from the Holocene phreatic activity of the Albano maar indicate sediment-water flows in excess of hundreds of cubic metres per second. Absolute age determinations of the paleosoil underlying one of the most recent deposits of the lahar succession at 5800 ± 100 yr B.P. ( 14C CAL) are in perfect agreement with the age of the overlying Eneolithic age settlements. The last catastrophic overflow is described in the Roman literature as a consequence of the anger of Poseidon against the Romans in 398 B.C. for their war against the Etruscans. In 394 B.C. the Romans decided to prevent the repetition of such events by the excavation through the maar crater wall of a 1.5 km long drain tunnel, which is still operational, keeping the lake 70 m below the lowest point of the maar rim. This tunnel drain may be regarded as the first prevention device for volcanic hazard in history and shows an unprecedented development of the engineering technology under the pressure of hazard perception.

    Context. Low-frequency radio arrays are opening a new window for the study of the sky, both to study new phenomena and to better characterize known source classes. Being flat-spectrum sources, blazars are so far poorly studied at low radio frequencies. Aims: We characterize the spectral properties of the blazar population at low radio frequency, compare the radio and high-energy properties of the gamma-ray blazar population, and search for radio counterparts of unidentified gamma-ray sources. Methods: We cross-correlated the 6100 deg2 Murchison Widefield Array Commissioning Survey catalogue with the Roma blazar catalogue, the third catalogue of active galactic nuclei detected by Fermi-LAT, and the unidentified members of the entire third catalogue of gamma-ray sources detected by Fermi-LAT. When available, we also added high-frequency radio data from the Australia Telescope 20 GHz catalogue. Results: We find low-frequency counterparts for 186 out of 517 (36%) blazars, 79 out of 174 (45%) gamma-ray blazars, and 8 out of 73 (11%) gamma-ray blazar candidates. The mean low-frequency (120-180 MHz) blazar spectral index is ⟨αlow⟩ = 0.57 ± 0.02: blazar spectra are flatter than the rest of the population of low-frequency sources, but are steeper than at ~GHz frequencies. Low-frequency radio flux density and gamma-ray energy flux display a mildly significant and broadly scattered correlation. Ten unidentified gamma-ray sources have a (probably fortuitous) positional match with low radio frequency sources. Conclusions: Low-frequency radio astronomy provides important information about sources with a flat radio spectrum and high energy. However, the relatively low sensitivity of the present surveys still misses a significant fraction of these objects. Upcoming deeper surveys, such as the GaLactic and Extragalactic All-Sky MWA (GLEAM) survey, will provide further insight into this population.

  8. Structural resistance of reinforced concrete buildings under pyroclastic flows: a study of the Vesuvian area

    The analysis of the effects of pyroclastic flows on humans and on buildings represents the main tool to define the boundary of the most hazardous area around an active volcano such as Somma-Vesuvius. Estimation of the lateral pressure on buildings derived from analogies with the damages observed after a nuclear explosion [Valentine (1998) J. Volcanol. Geotherm. Res. 87, 117-140] lead to pressure values and/or structural resistance which are not realistic (too high). Recent evidence [Baxter (2000) Human and Structural Vulnerability Assessment for Emergency Planning in a Future Eruption of Vesuvius. Final Report EC Project ENV4-CT98-0699; Young et al. (1997) EOS, Trans. Am. Geophys. Union, 78, 401] have shown that beyond 2-3 km from the vent, even after a great eruption, resistance to collapse of buildings affected by a pyroclastic flow is still possible. Neri et al. [(2000) Numerical simulation of pyroclastic flows. In: Human and Human and Structural Vulnerability Assessment for Emergency Planning in a Future Eruption of Vesuvius. Final Report EC Project ENV4-CT98-0699], by means of a numerical model of a collapsing column, show that the peak overpressures of the pyroclastic flows range from 1 to 2 kPa at a distance from the vent of about 4-5 km, where important historical centres of the Vesuvian area are located. A detailed analysis of urban settlement of the area [Cherubini et al. (2001) Vulnerabilita' Sismica dell'Area Vesuviana. Gruppo Nazionale per la Difesa dai Terremoti, CNR, Roma] has shown that most of the people live in reinforced concrete (r.c.) structures, not designed to resist horizontal seismic actions. The present work is aimed at analyzing the collapse limit load of r.c. structures to horizontal pressure for different structural design typologies (strong aseismic, weak aseismic, strong non-aseismic, weak non-aseismic). The simulations performed have also taken into account the specific features of the r.c. structures of the area (local building

    2013-02-01

    We present the first set of a new generation of models of massive stars with a solar composition extending between 13 and 120 M ⊙, computed with and without the effects of rotation. We included two instabilities induced by rotation: the meridional circulation and the shear instability. We implemented two alternative schemes to treat the transport of the angular momentum: the advection-diffusion formalism and the simpler purely diffusive one. The full evolution from the pre-main sequence up to the pre-supernova stage is followed in detail with a very extended nuclear network. The explosive yields are provided for a variety of possible mass cuts and are available at the Web site http://www.iasf-roma.inaf.it/orfeo/public_html. We find that both the He and the CO core masses are larger than those of their non-rotating counterparts. Also the C abundance left by the He burning is lower than in the non-rotating case, especially for stars with an initial mass of 13-25 M ⊙, and this affects the final mass-radius relation, basically the final binding energy, at the pre-supernova stage. The elemental yields produced by a generation of stars rotating initially at 300 km s-1 do not change substantially with respect to those produced by a generation of non-rotating massive stars, the main differences being a slight overproduction of the weak s-component and a larger production of F. Since rotation also affects the mass-loss rate, either directly or indirectly, we find substantial differences in the lifetimes as O-type and Wolf-Rayet subtypes between the rotating and non-rotating models. The maximum mass exploding as Type IIP supernova ranges between 15 and 20 M ⊙ in both sets of models (this value depends basically on the larger mass-loss rates in the red supergiant phase due to the inclusion of the dust-driven wind). This limiting value is in remarkably good agreement with current estimates.

    2007-01-01

    Background The present paper is a brief survey on the ethnobotanical works published by the Authors since 1981, concerning the research carried out in some southern and central Italian regions. Before Roman domination these territories were first inhabited by local people, while the southern areas were colonized by the Greeks. These different cultural contributions left certain traces, both in the toponyms and in the vernacular names of the plants and, more generally, in the culture as a whole. Methods Field data were collected through open interviews, mainly of farmers, shepherds and elderly people, born or living in these areas for a long time. Voucher specimens of collected plants are preserved in the respective herbaria of the Authors and in the herbarium of "Roma Tre" University. Important contributions have been made by several students native to the areas under consideration. A comparative analysis with local specific ethnobotanical literature was carried out. Results The paper reports several examples concerning human and veterinary popular medicine and in addition some anti-parasitic, nutraceutic, dye and miscellaneous uses are also described. Moreover vernacular names and toponyms are cited. Eight regions of central and southern Italy (particularly Latium, Abruzzo, Marche and Basilicata) were investigated and the data obtained are presented in 32 papers. Most of the species of ethnobotanical interest have been listed in Latium (368 species), Marche (274) and Abruzzo (203). The paper also highlights particularly interesting aspects or uses not previously described in the specific ethnobotanical literature. Conclusion Phyto-therapy in central and southern Italy is nowadays practised by a few elderly people who resort to medicinal plants only for mild complaints (on the contrary food uses are still commonly practised). Nowadays therapeutic uses, unlike in the past, are less closely or not at all linked to ritual aspects. Several plants deserve to be taken

    The animal and plant biodiversity of the Italian territory is known to be one of the richest in the Mediterranean basin and Europe as a whole, but does the genetic diversity of extant human populations show a comparable pattern? According to a number of studies, the genetic structure of Italian populations retains the signatures of complex peopling processes which took place from the Paleolithic to modern era. Although the observed patterns highlight a remarkable degree of genetic heterogeneity, they do not, however, take into account an important source of variation. In fact, Italy is home to numerous ethnolinguistic minorities which have yet to be studied systematically. Due to their difference in geographical origin and demographic history, such groups not only signal the cultural and social diversity of our country, but they are also potential contributors to its bio-anthropological heterogeneity. To fill this gap, research groups from four Italian Universities (Bologna, Cagliari, Pisa and Roma Sapienza) started a collaborative study in 2007, which was funded by the Italian Ministry of Education, University and Research and received partial support by the Istituto Italiano di Antropologia. In this paper, we present an account of the results obtained in the course of this initiative. Four case-studies relative to linguistic minorities from the Eastern Alps, Sardinia, Apennines and Southern Italy are first described and discussed, focusing on their micro-evolutionary and anthropological implications. Thereafter, we present the results of a systematic analysis of the relations between linguistic, geographic and genetic isolation. Integrating the data obtained in the course of the long-term study with literature and unpublished results on Italian populations, we show that a combination of linguistic and geographic factors is probably responsible for the presence of the most robust signatures of genetic isolation. Finally, we evaluate the magnitude of the diversity

    On the basis of cosmic ray and atmospheric electric field one minute data obtained by NM and EFS of Emilio Segre' Observatory (hight 2025 m above s.l., cut-off rigidity for vertical direction 10.8 GV) we determine the atmospheric electric field effect in CR for total neutron intensity and for multiplicities m=1, m=2, m=3, m=4, m=5, m=6, and m=7. For comparison and excluding primary CR variations we use also one minute data on neutron multiplicities obtained by NM of University "Roma Tre" (about sea level, cut-off rigidity 6.7 GV). In February 2000 were observed 14 periods of thun- derstorms with different durations (up to about 1000 min), the maximum strength of electric field was 110 kV/m. Thunderstorms were observed also in March 2000 (6 pe- riods with maximal field 112 kV/m), in April 2000 (9; 70 kV/m), in May 2000 (4; 10 kV/m), in October 2000 (10; 70 kV/m), in November 2000 (5; 50 kV/m), in De- cember 2000 (7; 88 kV/m), in January 2001 (12; 62 kV/m), in February 2001 (10; 88 kV/m). According to the theoretical calculations of Dorman and Dorman (1995) the electric field effect in the NM counting rate must be caused mainly by captchuring of slow negative muons by lead nucleus with escaping few neutrons. As it was shown in Dorman et al. (1999), the biggest electric field effect is expected in the multiplicity m=1, much smaller in m=2 and negligible effect is expected in higher multiplicities. We will control this conclusion on the basis of our experimental data. Obtained results give a possibility to estimate total acceleration and deceleration of CR particles by the atmospheric electric field. REFERENCES: Dorman L.I. and Dorman I.V., 1995.

    antecedentes: el estreñimiento es uno de los trastornos gastrointestinales más comunes en la población de edad avanzada porque con el paso de los años los factores implicados en su causa se modifican y repercuten en la ingestión de alimentos, el estado de nutrición y la actividad física. Objetivo: evaluar en el adulto mayor el efecto en el estreñimiento crónico del consumo de alimentos con alto contenido de fibra, el estado nutricio, y la actividad física. Material y métodos: estudio comparativo, prospectivo y transversal efectuado en 140 adultos mayores de la consulta externa de la Unidad de Medicina Familiar51 del Instituto Mexicano del Seguro Social en la ciudad de León, Guanajuato, durante el periodo del 4 mayo al 30 de octubre de 2009. Se valoró si padecían o no estreñimiento de acuerdo con los criterios de Roma III. Se valoró: peso,talla, circunferencia del brazo, pliegue cutáneo tricipital; se aplicó un cuestionario de actividad física validado, y se obtuvo el registro dietético de tres días (dos de entre semana y uno de sábado o domingo). Resultados: la ingestión promedio de fibra y agua no esultó estadísticamente diferente entre los grupos estudiados. Los pacientes con estreñimiento tuvieron dietas menos completas y variadas (p < 0.02; p < 0.03). El estado nutricio predominante en los adultos mayores de ambos grupos fue de sobrepeso (p= 0.49) pero el grupo sin estreñimiento tuvo niveles más altos de actividad física en comparación con los estreñidos (1664 vs 1049 METs, p= 0.004).Conclusiones: el menor nivel de actividad física, la monotonía en la dieta, y no incluir todos los grupos de alimentos son factores que se asocian con el estreñimiento en el adulto mayor. De acuerdo con los resultados de este estudio la menor ingestión de fibra no se relacionó con el estreñimiento.

    di Mauro, Ernesto

    Generation of RNA in abiotic conditions. Ernesto Di Mauro Dipartimento di Genetica Bi-ologia Molecolare, Universit` "Sapienza" Roma, Italy. a At least four conditions must be satisfied for the spontaneous generation of (pre)-genetic poly-mers: 1) availability of precursors that are activated enough to spontaneously polymerize. Preliminary studies showed that (a) nucleic bases and acyclonucleosides can be synthesized from formamide H2NCOH by simply heating with prebiotically available mineral catalysts [last reviewed in (1)], and that b) nucleic bases can be phosphorylated in every possible posi-tion [2'; 3'; 5'; cyclic 2',3'; cyclic 3',5' (2)]. The higher stability of the cyclic forms allows their accumulation. 2) A polymerization mechanism. A reaction showing the formation of RNA polymers starting from prebiotically plausible precursors (3',5' cyclic GMP and 3', 5'cyclic AMP) was recently reported (3). Polymerization in these conditions is thermodynamically up-hill and an equilibrium is attained that limits the maximum length of the polymer produced to about 40 nucleotides for polyG and 100 nucleotides for polyA. 3) Ligation of the synthesized oligomers. If this type of reaction could occur according to a terminal-joining mechanism and could generate canonical 3',5' phosphodiester bonds, exponential growth would be obtained of the generated oligomers. This type of reaction has been reported (4) , limited to homogeneous polyA sequences and leading to the production of polyA dimers and tetramers. What is still missing are: 4) mechanisms that provide the proof of principle for the generation of sequence complexity. We will show evidence for two mechanisms providing this proof of principle for simple complementary sequences. Namely: abiotic sequence complementary-driven terminal ligation and sequence-complementary terminal growth. In conclusion: all the steps leading to the generation of RNA in abiotic conditions are satisfied. (1) R Saladino, C Crestini, F

  18. Debate: Limitations on universality: the "right to health" and the necessity of legal nationality

    PubMed Central

    2010-01-01

    Background The "right to health," including access to basic healthcare, has been recognized as a universal human right through a number of international agreements. Attempts to protect this ideal, however, have relied on states as the guarantor of rights and have subsequently ignored stateless individuals, or those lacking legal nationality in any nation-state. While a legal nationality alone is not sufficient to guarantee that a right to healthcare is accessible, an absence of any legal nationality is almost certainly an obstacle in most cases. There are millions of so-called stateless individuals around the globe who are, in effect, denied medical citizenship in their countries of residence. A central motivating factor for this essay is the fact that statelessness as a concept is largely absent from the medical literature. The goal for this discussion, therefore, is primarily to illustrate the need for further monitoring of health access issues by the medical community, and for a great deal more research into the effects of statelessness upon access to healthcare. This is important both as a theoretical issue, in light of the recognition by many of healthcare as a universal right, as well as an empirical fact that requires further exploration and amelioration. Discussion Most discussions of the human right to health assume that every human being has legal nationality, but in reality there are at least 11 to 12 million stateless individuals worldwide who are often unable to access basic healthcare. The examples of the Roma in Europe, the hill tribes of Thailand, and many Palestinians in Israel highlight the negative health impacts associated with statelessness. Summary Stateless individuals often face an inability to access the most basic healthcare, much less the "highest attainable standard of health" outlined by international agreements. Rather than presuming nationality, statelessness must be recognized by the medical community. Additionally, it is imperative

    the first archaic settlement (late 6th cent. BC) was unearthed. The Graeco-Roman town expanded downhill, exploiting the growth of a coastal plain, where occasional phases of flooding coexisted with the life of the citizens [6]. The onset of the 3rd cent. AD was characterized by phases of extreme floods which also occurred during the 4th and 5th cent. AD leading to several meters of ground-level aggradation and the burial of buildings [6, 7]. Although the three investigated sites are located in rather different morphological context, they show the evidence of a disequilibrium in the morphodynamics which started in the 3rd-4th cent. AD. The vast amount of collected data strongly suggest that this disequilibrium is a clear sign of a socio-economic decline which affected the Roman Empire during this period rather than the consequence of a climatic deterioration towards dryer conditions, for which no detailed data are available in the Mediterranean area [8]. The abandonment of the towns and their surroundings triggered increased soil erosion on the slopes suffering deforestation and in the farmlands for reduced maintenance, enhancing accumulation rates at the foothills and along coastal areas.

    "Roma Tre" University, Applied Electronics Dept.v. Vasca Navale 84, 00146 Rome, Italy Non-invasive identification of buried objects in the near-field of a receiver array is a subject of great interest, due to its application to the remote sensing of the earth's subsurface, to the detection of landmines, pipes, conduits, to the archaeological site characterization, and more. In this work, we present a Sub-Array Processing (SAP) approach for the detection and localization of subsurface perfectly-conducting circular cylinders. We consider a plane wave illuminating the region of interest, which is assumed to be a homogeneous, unlossy medium of unknown permittivity containing one or more targets. In a first step, we partition the receiver array so that the field scattered from the targets result to be locally plane at each sub-array. Then, we apply a Direction of Arrival (DOA) technique to obtain a set of angles for each locally plane wave, and triangulate these directions obtaining a collection of crossing crowding in the expected object locations [1]. We compare several DOA algorithms such as the traditional Bartlett and Capon Beamforming, the Pisarenko Harmonic Decomposition (PHD), the Minimum-Norm method, the Multiple Signal Classification (MUSIC) and the Estimation of Signal Parameters via Rotational Techinque (ESPRIT) [2]. In a second stage, we develop a statistical Poisson based model to manage the crossing pattern in order to extract the probable target's centre position. In particular, if the crossings are Poisson distributed, it is possible to feature two different distribution parameters [3]. These two parameters perform two density rate for the crossings, so that we can previously divide the crossing pattern in a certain number of equal-size windows and we can collect the windows of the crossing pattern with low rate parameters (that probably are background windows) and remove them. In this way we can consider only the high rate parameter windows (that most

Finally, at the end of the growing season the oats crop was harvested following a (50x50 cm) grid sampling pattern and each collected cereal bundle was tested for its isotopic signature. Results showed that the isotopic monitoring of the simulated CO2 leaks enabled to characterize finely the 3 dimensional extent of the leak within the soil-atmosphere continuum, including the assimilation of leaking CO2 by the vegetation.

  7. The Italian contribution to the CSES satellite

    2016-04-01

    We present the Italian contribution to the CSES (China Seismo-Electromagnetic Satellite) mission. The CSES satellite aims at investigating electromagnetic field, plasma and particles in the near-Earth environment in order to study in particular seismic precursors, particles fluxes (from Van Allen belts, cosmic rays, solar wind, etc.), anthropogenic electromagnetic pollution and more in general the atmosphere-ionosphere-magnetosphere coupling mechanisms that can affect the climate changes. The launch of CSES - the first of a series of several satellite missions - is scheduled by the end of 2016. The CSES satellite has been financed by the CNSA (China National Space Agency) and developed by CEA (China Earthquake Administration) together with several Chinese research institutes and private companies such as the DFH (that has developed the CAST2000 satellite platform). Italy participates to the CSES satellite mission with the LIMADOU project funded by ASI (Italian Space Agency) in collaboration with the Universities of Roma Tor Vergata, Uninettuno, Trento, Bologna and Perugia, as well as the INFN (Italian National Institute of Nuclear Physics), INGV (Italian National Institute of Geophysics and Volcanology) and INAF-IAPS (Italian National Institute of Astrophysics and Planetology). Many analyses have shown that satellite observations of electromagnetic fields, plasma parameters and particle fluxes in low Earth orbit may be useful in order to study the existence of electromagnetic emissions associated with the occurrence of earthquakes of medium and high magnitude. Although the earthquakes forecasting is not possible today, it is certainly a major challenge - and perhaps even a duty - for science in the near future. The claims that the reported anomalies (of electromagnetic, plasma and particle parameters) are seismic precursors are still intensely debated and analyses for confirming claimed correlations are still lacking. In fact, ionospheric currents, plasma

Particular care was given to organic clays within the lacustrine deposits, which show a stronger linearity and lower damping ratio with respect to inorganic clays of similar plasticity. The collected geological-geophysical dataset suggests the coalescence of several eruptive centres localized at different depths and laterally distributed within the present-day Stracciacappa maar. Data are currently processed for subsequent 2D and 3D numerical simulations of site effects. REFERENCES De Rita D. and Zanetti G., 1986.

    the low altitudes (3-5 meters) will help geophysical cover all the studied area with a regular observation step (Eppelbaum, 2008). At the final step all these measurements (including results of the previous works) could be compiled to 4D models of different geophysical parameters (Eppelbaum and Ben-Avraham, 2002; Eppelbaum et al., 2010). Analysis of temperature field in the boreholes drilled in the vicinity of the studied site will permit to estimate the temperature (e.g., Eppelbaum et al., 2006c) in the historical period when this artifact was constructed and, correspondingly, utilize this characteristic for investigation of mechanical and other properties of the ancient building material. Studying of temporal variations of magnetic (e.g., Finkelstein and Eppelbaum) and VLF fields can be also used for determination of nature of some buried ancient remains. The geophysical investigations must be combined with geochemical, paleostructural, paleobiogeographical, paleomorphological and other methods (Eppelbaum et al., 2010). Application of informational parameters (Khesin et al., 1996; Eppelbaum et al., 2003b) will permit to present all available data by the use of integral convolution units.

Finally, a set of dedicated talks on the interplay between the top sector and other hot subjects, like the Higgs and SUSY, were given both at the theory and experimental level. Furthermore, ad hoc student sessions were organized to allow younger colleagues to pose questions to the senior experts in the field and contribute with their more recent studies. The conference has been a definitive success, not just scientifically: about 130 participants from all over the world created a collegiate spirit which culminated in the social events at Winchester Hall below King Arthur's table; and in a cosy 16th century barn for the social dinner. The Local Organizing Committee would like to thank all participants, and in particular the speakers, for their high level contributions to TOP 2012 and for making this a very fruitful and pleasant time together.

    The lack of long and reliable time series of solar spectral irradiance (SSI) measurements makes an accurate quantification of solar contributions to recent climate change difficult. Whereas earlier SSI observations and models provided a qualitatively consistent picture of the SSI variability, recent measurements by the SORCE (SOlar Radiation and Climate Experiment) satellite suggest a significantly stronger variability in the ultraviolet (UV) spectral range and changes in the visible and near-infrared (NIR) bands in anti-phase with the solar cycle. A number of recent chemistry-climate model (CCM) simulations have shown that this might have significant implications on the Earth's atmosphere. Motivated by these results, we summarize here our current knowledge of SSI variability and its impact on Earth's climate. We present a detailed overview of existing SSI measurements and provide thorough comparison of models available to date. SSI changes influence the Earth's atmosphere, both directly, through changes in shortwave (SW) heating and therefore, temperature and ozone distributions in the stratosphere, and indirectly, through dynamical feedbacks. We investigate these direct and indirect effects using several state-of-the art CCM simulations forced with measured and modelled SSI changes. A unique asset of this study is the use of a common comprehensive approach for an issue that is usually addressed separately by different communities. We show that the SORCE measurements are difficult to reconcile with earlier observations and with SSI models. Of the five SSI models discussed here, specifically NRLSSI (Naval Research Laboratory Solar Spectral Irradiance), SATIRE-S (Spectral And Total Irradiance REconstructions for the Satellite era), COSI (COde for Solar Irradiance), SRPM (Solar Radiation Physical Modelling), and OAR (Osservatorio Astronomico di Roma), only one shows a behaviour of the UV and visible irradiance qualitatively resembling that of the recent SORCE

    value -referring to biodiversity, geodiversity, culture- which can be considered as a special heritage. Starting from the concept of Geomorphosite, a geomorphologic landform with a scientific, cultural and socio-economical value (Panizza 2001), we propose a further definition, useful in the preliminary steps of the landscape analysis: "geomorpho-landscape" as a spatial object or component of a geological landscape, whose geo-morphological evolution, linked to the geological setting, are elements of aesthetical, semiological as well as historical and cultural value. The structure of the landscape is represented by the physical shape and spatial organization, in dynamic way: it is necessary to provide a readout of the landscape components that supplements the geo-morphological, lithological, geodiversity data (Lugeri et alii, 2012). The concept of "geomorpho-landscape" is conceived to address the need to describe by a synthetic approach the geological processes emerging at the landscape scale, allowing to link spatial patterns to geological processes Each geo-form has in itself geological, geo-morphological, landmark, historical and cultural features, of such special relevance, that they can be defined in terms of scientific quality, rarity, aesthetic appeal and educational and cultural value.

    "Applications of Ground Penetrating Radar in urban areas: the sensitive case of historical cities." The Action TU1208 is coordinated by "Roma Tre University" (Rome, Italy) and the TS was hosted by the Cracow University of Technology (Cracow, Poland). It was attended by 25 PhD students and early-career investigators coming from Albania, Belgium, Germany, Italy, Poland, Romania, Russia and Slovenia. Trainers and Trainees had the great honour and privilege to carry out practical sessions in St Leonard's Crypt, in cooperation with the companies Restauro (Toruń, Poland) and Geoservice (Athens, Greece). Over the centuries, city centres have been continuously changing, developing and adapting to the requirements of society, architectural planning and advancing technology. Under the pressure of urbanisation, many cities and towns have significantly expanded and the limited space in their centres has been exploited more intensively. The shallow subsurface of historical cities is nowadays a very complicated scenario including reams of pipes, cables, rubble, bars and slabs of reinforced concrete, backfilled excavation trenches and pits, cellars, wells, cavities, tunnels, graves, walls and foundations of former houses, churches, monasteries, town fortifications, along with several other modern and ancient structures and manufacts. For the prospection of such a diversified, multilayered, intricate and complex underground environment, both for archaeological and civil-engineering purposes, Ground Penetrating Radar (GPR) is a very effective non-destructive geophysical method. GPR is a powerful tool not only for the prospection of subsurface but also for the non-invasive testing of historical buildings, fountains, historical bridges, sculptures, frescoes, pottery and other objects collected in museums: it can give information about their state of preservation, it can significantly help to address a restoration project properly, and sometimes it can also help to achieve information of

    2010-05-01

    The work presented here is the continuation of " Sinkhole Project of Latium Region" (2002), carried out by Researchers of the Laboratory of Applied Geology and Hydrogeology of the Department of Geological Sciences of the University "Roma Tre", Rome (Italy), through which were found, in different plain of the whole Region, Sinkhole prone areas, using a methodology based on the superimposition of thematic layers corresponding to geological and anthropogenic breaking factors. In the last years several specific investigations have been conducted by Researchers of the Laboratory in the Pontina Plain, that is located in the south west of the Latium Region, concerning the geological-stratigraphic setting, the sketch of flow in the aquifers located in the Pontine depression, the chemiphysical groundwater characheteristics, the density of wells, the amount of well pumping and piezometric changes. This required the implementation of several piezometric and chemiphysical surveys, the collection and validation of a large number of stratigraphic and geophysical data. All data in the archive have been computerized and the maps vectorized. This makes it possible today to address the analysis with Geographical Information Systems and to start numerical flow simulations, regarding both the heavily drained deep confined aquifer, and the areas subject to the presence of an important water exchange between the recharge area in the Lepini Mountains (carbonatic ridge) and terrigenous aquifers of the plain. Among the main causes that trigger the catastrophic collapses there are, in fact, all the phenomena that cause the mass density reduction through erosion, leaching, dissolution. All these agents are associated with water circulation: flow, velocity, CO2 saturation rate, carbonates saturation rate. The spread in the Pontina plain of deep and high pumping wells, wrongly built without the correct way of progress, and without the realization of cemented portions properly located, can lead

  17. ERS-ENVISAT InSAR deformation time-series: a powerful tool to investigate long term surface deformation of large areas

    NASA Astrophysics Data System (ADS)

    Lanari, Riccardo

    2010-05-01

    Satellite time series have already provided key measurements to retrieve information on the dynamic nature of Earth surface processes. We exploit in this work the availability of the large archives of spaceborne Synthetic Aperture Radar (SAR) data acquired by the ERS-1/2 and ENVISAT sensors of the European Space Agency (ESA) during the 1992-2009 time period, in order to investigate long term surface deformation of large areas. To achieve this result we take advantage of the Differential SAR Interferometry (InSAR) algorithm referred to as Small BAseline Subset (SBAS) technique (Berardino et al., 2002), which allows us to generate mean deformation velocity maps and corresponding time-series by exploiting temporally overlapping SAR dataset collected by the ERS and ENVISAT sensors (Pepe et al., 2005). In particular, we focus on the results obtained by retrieving ERS-ENVISAT deformation time-series from 1992 till today in selected case studies relevant to different scenarios. We start from the analysis of the Mt. Etna volcano (Italy) and the Napoli Bay area (Italy), the latter including three volcanic systems (the Campi Flegrei caldera, the Somma-Vesuvio volcanic complex and the Ischia island) and the city of Napoli. In addition, we present the results relevant to the cities of Istanbul (Turkey) and Roma (Italy). The overall analyses are carried out by using averaged (multilook) InSAR interferograms with a spatial resolution of about 100 x 100 m. Moreover, in selected zones we further investigate localized phenomena by zooming in the areas of interest and carrying out a InSAR analysis at full spatial resolution scale (Lanari et al., 2004). In these cases we also exploit the doppler centroid variations of the post-2000 acquisitions of the ERS-2 sensor and the carrier frequency difference between the ERS-1/2 and the ENVISAT systems in order to maximize the number of investigated SAR pixels and to improve their geocoding. The presented results demonstrate the unique

    -documented earthquakes and tsunamis, we could not find a clearly recorded sedimentary impact; - non earthquake-triggered MTDs (as the 1963 event) produced specific layers identical to the major earthquakes impacts. At the difference, for a few cores from the deep axial floor, several sandy or silty turbidites permit to establish correlations: i) between coring sites, ii) with earthquakes which stroke two different areas, respectively east and west of the concerned part of the Gulf. Furthermore, the sedimentary events show a particular time distribution for the last 600 yr: - two intervals with short recurrences: a recent one (~1900 AD-Present or ~1750 AD-Present) and an older one (~1550 AD-1700 AD or ~1450 AD-1800 AD); these time distributions differ from each coring site; - a long "quiet" period (150 to 200 yr). From these results, we tentatively consider this sedimentary record as an indicator of a migration of seismogenic faulting activity. Ref.: Albini, P., et al., 2014. Techn. Rep. I.N.G.V. Roma.

    This work aims at presenting the scientific results stemming from six Short-Term Scientific Missions (STSMs) funded by the COST (European COoperation in Science and Technology) Action TU1208 'Civil Engineering Applications of Ground Penetrating Radar' (Action Chair: Lara Pajewski, STSM Manager: Marian Marciniak). STSMs are important means to develop linkages and scientific collaborations between participating institutions involved in a COST Action. Scientists have the possibility to go to an institution abroad, in order to undertake joint research and share techniques/equipment/infrastructures that may not be available in their own institution. STSMs are particularly intended for Early Stage Researchers (ESRs), i.e., young scientists who obtained their PhD since no more than 8 years when they started to be involved in the Action. Duration of a standard STSM can be from 5 to 90 days and the research activities carried out during this short stay shall specifically contribute to the achievement of the scientific objectives of the supporting COST Action. The first STSM was carried out by Lara Pajewski, visiting Antonis Giannopoulos at The University of Edinburgh (United Kingdom). The research activities focused on the electromagnetic modelling of Ground Penetrating Radar (GPR) responses to complex targets. A set of test scenarios was defined, to be used by research groups participating to Working Group 3 of COST Action TU1208, to test and compare different electromagnetic forward- and inverse-scattering methods; these scenarios were modelled by using the well-known finite-difference time-domain simulator GprMax. New Matlab procedures for the processing and visualization of GprMax output data were developed. During the second STSM, Iraklis Giannakis visited Lara Pajewski at Roma Tre University (Italy). The study was concerned with the numerical modelling of horn antennas for GPR. An air-coupled horn antenna was implemented in GprMax and tested in a realistically

Thus we argue that host star C/O abundance is an important ingredient in assessing a key factor in habitability of exoplanet systems - the availability of abundant ice beyond the ice line. Efforts should continue to improve and further validate techniques for measuring this important metric. TVJ acknowledges government support at JPL/Caltech, under a contract with NASA.

    Spectra obtained on Lunar highland and on Mercury show low contrast features. We suggest the interference of adjacent absorptions bands due to different minerals as a possible cause of low contrast spectra. While the combined effects of Fe2+ absorptions in various clinopyroxene, orthopyroxene and olivine mixtures have been widely studied, the spectroscopic effects of plagioclase have been considered only for <0,26 wt% FeO-bearing compositions, even if plagioclase is considered an important constituent of Lunar and Hermean terrains. Here we consider mixtures composed by various abundances of multimineral grains and plagioclase, separated from cumulate rocks of a layered intrusion belonging to the anorthosite kindred. Three different Fe, Mg multimineral compositions have been considered. The first is olivine-free and consists of clinopyroxene En45-Wo46 (43.9%) and orthopyroxene En77 (56.1%). The second one is olivine-poor and includes orthopyroxene En86 (70%) and olivine Fo87 (30%). The third one, olivine-rich, is composed by orthopyroxene En82 (28.2%), clinopyroxene En45-Wo46 (3.4%), olivine Fo84 (68.4%). Two distinct plagioclase compositions, having FeO wt.% concentration of 0.36 (medium-iron), and 0.5 (rich-iron) were systematically mixed to each starting assemblage. The amount of plagioclase in the mixtures ranges between 30% and 90%. Mixtures with grain sizes of 63-125 μm and 125-250 μm were prepared. Bidirectional reflectance spectra (i=30°, e=0° angle phase) on these mixtures were acquired at the SLAB (Spectroscopy Laboratory, Iasf-INAF, Roma) in the VIS-NIR range (0.3-2.5 µm). Preliminary results show that increasing plagioclase content produces higher albedo and lower spectral contrast. In olivine-free mixtures, plagioclase produces a flattening in the 1.2 µm region at about 70% of medium-iron plagioclase and 50% of iron-rich plagioclase; for higher content of plagioclase a clear absorption band appears. In olivine-poor mixtures, the presence of

    With the advent of high-velocity shear apparatus, several experimental studies have been conducted in recent years improving our understanding of fault friction at seismic slip rates (0.1-10 m/s). Here, we present the results of a series of tests conducted on Westerly granite, at INGV Roma, on a Slow to HIgh Velocity Apparatus (SHIVA), coupled with a high frequency monitoring (4MHz sampling rate). Experiments were conducted under normal stress (σn) ranging from 5 to 20 MPa and at sliding velocities (V) comprised between 3 mm/s and 3 m/s. Additional experiments were conducted in the presence of pore fluid at equivalent effective normal stress. In dry conditions, two friction drops are observed. The first drop is independent of the normal stress and occurs when V become higher than a critical value (Vc≈0.15 m/s). The second friction drop occurs after a critical slip weakening distance which decreases as a power law with the power density (τV). The first, abrupt, drop is explained by flash heating and weakening mechanism while the second, smooth, drop is due to the formation and growth of molten patches on the fault surface. In wet conditions, only the second drop of friction is observed. Average values of the fracture energy are independent of normal stress and sliding velocity at V > 0.01 m/s. However, measurements of elastic wave velocities travelling through the fault strongly suggest that higher damage is induced for 0.1 < V < 0.3 m/s for a same finite displacement. This observation is also supported by acoustic emission (AE) recordings. Indeed, most the AEs are recorded after the initiation of the second friction drop, that is, once the fault surface temperature is high. Some AEs are even recorded few seconds after the end of the experiments, suggesting they may be due to thermal cracking induced by heat diffusion. In addition, the presence of pore fluid pressure (water) delayed the apparition of AEs at equivalent effective pressure, supporting the link

Starting from the concept of Geomorphosite, a geomorphologic landform with a scientific, cultural and socio-economical value (Panizza 2001), we propose a further definition, useful in the preliminary steps of the landscape analysis: "geomorpho-landscape" as a spatial object or component of a geological landscape, whose geo-morphological evolution, linked to the geological setting, are elements of aesthetical, semiological as well as historical and cultural value. The structure of the landscape is represented by the physical shape and spatial organization, in dynamic way: it is necessary to provide a readout of the landscape components that supplements the geo-morphological, lithological, geodiversity data (Lugeri et alii, 2012). The concept of "geomorpho-landscape" is conceived to address the need to describe by a synthetic approach the geological processes emerging at the landscape scale, allowing to link spatial patterns to geological processes Each geo-form has in itself geological, geo-morphological, landmark, historical and cultural features, of such special relevance, that they can be defined in terms of scientific quality, rarity, aesthetic appeal and educational and cultural value.

    Ground Penetrating Radar (GPR) is a safe, non-destructive and non-invasive imaging technique that can be effectively used for advanced inspection of composite structures and for diagnostics affecting the whole life-cycle of civil engineering works. GPR can also be successfully employed in archaeological prospecting and cultural heritage diagnostics. In many Countries, where the archeological patrimony is an outstanding value (as Egypt, Israel, Greece, Central and South America), GPR is usually employed both as a diagnostic tool for the preventive detection of archeological structures and as the most advanced instrument able to prospect geometry and shape of underground valuable sites. However many uncertainties persist, because of several difficulties and ambiguities due to the complexity of the image processing in heterogeneous environment. It is possible to identify three main areas, in GPR field, that have to be addressed in order to promote the use of this technology in archaeological prospecting and cultural heritage diagnostics. These are: a) increase of the system sensitivity to enable the usability in a wider range of conditions, archeological sites are often located in impervious and critical environments; b) research novel data processing algorithms/analysis tools for the interpretation of GPR results; c) contribute to the development of new standards and guidelines and to training of end users, that will also help to increase the awareness of operators. It is also important to further investigate and promote a combined use of GPR with other non-invasive advanced techniques, typically used in the archeological investigation. In this framework, the COST Action TU1208 "Civil Engineering Applications of Ground Penetrating Radar", proposed by a research team of "Roma Tre" University, Rome, Italy, has been approved in November 2012 and is going to start in April 2013. It is a 4-years ambitious project already involving 17 European Countries (AT, BE, CH, CZ, DE

    "Applications of Ground Penetrating Radar in urban areas: the sensitive case of historical cities." The Action TU1208 is coordinated by "Roma Tre University" (Rome, Italy) and the TS was hosted by the Cracow University of Technology (Cracow, Poland). It was attended by 25 PhD students and early-career investigators coming from Albania, Belgium, Germany, Italy, Poland, Romania, Russia and Slovenia. Trainers and Trainees had the great honour and privilege to carry out practical sessions in St Leonard's Crypt, in cooperation with the companies Restauro (Toruń, Poland) and Geoservice (Athens, Greece). Over the centuries, city centres have been continuously changing, developing and adapting to the requirements of society, architectural planning and advancing technology. Under the pressure of urbanisation, many cities and towns have significantly expanded and the limited space in their centres has been exploited more intensively. The shallow subsurface of historical cities is nowadays a very complicated scenario including reams of pipes, cables, rubble, bars and slabs of reinforced concrete, backfilled excavation trenches and pits, cellars, wells, cavities, tunnels, graves, walls and foundations of former houses, churches, monasteries, town fortifications, along with several other modern and ancient structures and manufacts. For the prospection of such a diversified, multilayered, intricate and complex underground environment, both for archaeological and civil-engineering purposes, Ground Penetrating Radar (GPR) is a very effective non-destructive geophysical method. GPR is a powerful tool not only for the prospection of subsurface but also for the non-invasive testing of historical buildings, fountains, historical bridges, sculptures, frescoes, pottery and other objects collected in museums: it can give information about their state of preservation, it can significantly help to address a restoration project properly, and sometimes it can also help to achieve information of

[2] By carefully splitting up the faint light coming from a galaxy into its component colours using powerful telescopes and spectrographs, astronomers can identify the fingerprints of different chemicals in remote galaxies, and measure the amounts of heavy elements present. With the SINFONI instrument on the VLT astronomers can go one better and get a separate spectrum for each part of an object. This allows them to make a map that shows the quantity of heavy elements present in different parts of a galaxy and also determine where in the galaxy star formation is occurring most vigorously.

    its particular buoyancy drives the advance of the current, with a different celerity from the tail. The head is highly concentrated being the main engine of convection of the released mass, being subjected to entrainment at the interface with the ambient fluid. The aim of the present work is to experimentally investigate the dynamics of the head, including continuous entrainment and cycles of stretching and breaking observed in the laboratory. Experiments were conducted at the Laboratory of Hydraulics of University of Rome "Roma Tre" in a 3.0 m long, 0.20 m wide and 0.30 m deep transparent Perspex flume. Four lock-exchange release tests were performed varying the density of the saline water. For smooth bed and for a fixed value of water depth, h = 0.20 m, the following four different initial densities of the salt-water mixture were analysed: 1015, 1030, 1045 and 1060 kg/m3. A controlled quantity of dye is added to the saline water in the lock to provide flow visualization and to serve as density tracer. The development of the current is recorded with a 25 Hz CCD camera under controlled light conditions. The resulting video frames are thus converted into grey scale matrices and a calibration procedure establishes a non-linear relation, experimentally determined, between the gray scale values and the quantity of dye in the water. The quantity of dye is converted into salt concentration by assuming a linear relation between quantities, dye and salt, allowing thus the estimation of the 2D instantaneous current density distribution. The experiments allowed the observation of the dynamics of the head of unsteady density currents in detail, including a cyclic increase in dimension and mass due to entrainment followed by a division in two distinct patches. A frontal one continues the drive downstream whereas a subsequent one is left behind and incorporated in the tail, thus indicating that the loss of saline mass in the head is not only due to continuous entrainment at the

ROV observations also permit to realize a multimodel approach to magnetic data analysis (Eppelbaum, 2005). Results of performed 3D modeling confirm an effectiveness of the proposed ROV low-altitude survey. Khesin's methodology (Khesin et al., 2006) for estimation of upper geological section magnetization consists of land magnetic observations along a profile disposing under inclined relief with the consequent data processing (this method cannot be applied at flat topography). The improved modification of this approach is based on combination of straight and inclined ROV observations that will help to obtain parameters of the medium magnetization with areas of flat terrain relief.

    can be used by GPR operators to identify the signatures generated by uncommon targets or by composite structures. Repeated evaluations of the electromagnetic field scattered by known targets can be performed by a forward solver, in order to estimate - through comparison with measured data - the physics and geometry of the region investigated by the GPR. It is possible to identify three main areas, in the GPR field, that have to be addressed in order to promote the use of this technology in the civil engineering. These are: a) increase of the system sensitivity to enable the usability in a wider range of conditions; b) research novel data processing algorithms/analysis tools for the interpretation of GPR results; c) contribute to the development of new standards and guidelines and to training of end users, that will also help to increase the awareness of operators. In this framework, the COST Action TU1208 "Civil Engineering Applications of Ground Penetrating Radar", proposed by Lara Pajewski, "Roma Tre" University, Rome, Italy, has been approved in November 2012 and is going to start in April 2013. It is a 4-years ambitious project already involving 17 European Countries (AT, BE, CH, CZ, DE, EL, ES, FI, FR, HR, IT, NL, NO, PL, PT, TR, UK), as well as Australia and U.S.A. The project will be developed within the frame of a unique approach based on the integrated contribution of University researchers, software developers, geophysics experts, Non-Destructive Testing equipment designers and producers, end users from private companies and public agencies. The main objective of the COST Action TU1208 is to exchange and increase scientific-technical knowledge and experience of GPR techniques in civil engineering, whilst promoting the effective use of this safe and non-destructive technique in the monitoring of systems. In this interdisciplinary Action, advantages and limitations of GPR will be highlighted, leading to the identification of gaps in knowledge and technology

      published by Plenum Press in 1990, are still a classic in surface science, and we often refer to them as the 'red book' by the colour of its cover reminiscent of another more famous book. But I do not wish to dwell upon pleasant memories of my relationship with Virginio Bortolani any longer. We should better record a few important facts of his broad activity. J P Toennies will outline Bortolani's achievements in the field of surface phonons and vibrations in a review article of this volume. So I would like to stress other very important contributions of his to the scientific development in this country and to the international community. In the late seventies surface physics was being studied by very few and tiny groups in Italy (mainly at Genova, Milano and Roma Universities). But Bortolani was able to form the first theoretical group of international reputation in this field in Italy at Modena University. In this respect he was surely helped by his previous experience at the Cavendish Laboratory working with V Heine on the theory of pseudopotentials and with N Mott. This allowed him to be at the forefront of condensed matter theory so that to propose and carry out exciting research subjects. Bortolani also supervised all the initiatives in the 70s and 80s from which Modena has grown so much as to be now considered an internationally recognized centre of surface science and nanotechnology. Second, by organizing a conference in Modena every year the week before Christmas (the so-called Congressino di Modena by the Italian participants), he promoted the diffusion of surface physics in the country: it became soon traditional for bright young physicists to come to Modena on that occasion, and, because of the exciting and friendly atmosphere, to turn to surface investigations. The catalysing activity of Bortolani is also confirmed by the number of his students who have matured into excellent scientists or technologists: Carlo Calandra, Carlo Maria Bertoni, Franca Manghi

      This work aims at presenting the scientific results stemming from six Short-Term Scientific Missions (STSMs) funded by the COST (European COoperation in Science and Technology) Action TU1208 'Civil Engineering Applications of Ground Penetrating Radar' (Action Chair: Lara Pajewski, STSM Manager: Marian Marciniak). STSMs are important means to develop linkages and scientific collaborations between participating institutions involved in a COST Action. Scientists have the possibility to go to an institution abroad, in order to undertake joint research and share techniques/equipment/infrastructures that may not be available in their own institution. STSMs are particularly intended for Early Stage Researchers (ESRs), i.e., young scientists who obtained their PhD since no more than 8 years when they started to be involved in the Action. Duration of a standard STSM can be from 5 to 90 days and the research activities carried out during this short stay shall specifically contribute to the achievement of the scientific objectives of the supporting COST Action. The first STSM was carried out by Lara Pajewski, visiting Antonis Giannopoulos at The University of Edinburgh (United Kingdom). The research activities focused on the electromagnetic modelling of Ground Penetrating Radar (GPR) responses to complex targets. A set of test scenarios was defined, to be used by research groups participating to Working Group 3 of COST Action TU1208, to test and compare different electromagnetic forward- and inverse-scattering methods; these scenarios were modelled by using the well-known finite-difference time-domain simulator GprMax. New Matlab procedures for the processing and visualization of GprMax output data were developed. During the second STSM, Iraklis Giannakis visited Lara Pajewski at Roma Tre University (Italy). The study was concerned with the numerical modelling of horn antennas for GPR. An air-coupled horn antenna was implemented in GprMax and tested in a realistically

      to provide collisions for the experiments at the end of 2008. In the meanwhile the only running accelerator able to provide collisions suitable for the search of the Higgs boson is the Tevatron at Fermilab, a proton-antiproton collider with a center of mass energy of 1.96 TeV working at 3 • 1032cm-2s-1 peak luminosity. These features make the Tevatron able for the direct search of the Higgs boson in the 115-200 GeV mass range. Since the coupling of the Higgs boson is proportional to the masses of the particles involved, the decay in b{bar b} has the largest branching ratio for Higgs mass < 135 GeV and thus the events Z/W + $b\\bar{b}$ are the main background to the Higgs signal in the most range favored by Standard Model fits. In this thesis a new technique to identify Heavy Flavour quarks inside high - PT jets is applied to events with a reconstructed Z boson to provide a measurement of the Z+b and Z+c inclusive cross sections. The study of these channels represent also a test of QCD in high transferred momentum regime, and can provide information on proton pdf. This new Heavy Flavour identication technique (tagger) provides an increased statistical separation between b, c and light flavours, using a new vertexing algorithm and a chain of artificial Neural Networks to exploit as much information as possible in each event. For this work I collaborated with the Universita di Roma 'La Sapienza' group working in the CDF II experiment at Tevatron, that has at first developed this tagger. After a brief theoretical introduction (chapter 1) and a description of the experimental apparatus (chapter 2), the tagger itself and its calibration procedure are described in chapter 3 and 4. The chapter 5 is dedicated to the event selection and the chapter 6 contains the results of the measurement and the study of the systematic errors.

Direct "in situ" field evaluations have to be preferred in any case to indirect deductions from other soil characteristics measured under laboratory conditions in the same soils, or in other soils, through the so called "pedo-transfer" functions, or through the use of stochastic models such as the SCS Curve Number Method, or of other models using empirical or physical approaches, which have demonstrated to be of limited value in most of the cases.

      considered as a sort of pseudo-stratigraphy, since they are the oldest feature that can be traced continuously at the map scale. For this reason we have developed a set of attributes identifying the tectonic and lithological units (a "legend"), implemented both in the GIS database and in the 3D models, which at the same time is compatible with the data structure of 3D modelling packages like Move and Skua/Gocad, and allows tracing the complex hierarchic classification of the units mapped in the GIS. This allows for the almost automatic and consistent two-way transfer of data between the GIS and geomodelling environments. E.g. results of 3D modelling, which is based on input data originally stored in the GIS, will eventually be transferred back to the GIS. The results of this study, which are preliminarily presented here, will open new opportunities to study the collision- and subduction-related nappe architecture and kinematics with younger deformations removed, and will eventually lead (with additional studies) to a step-by-step retrodeformation supported by modern technologies, following the path traced by Argand at the beginning of the 20th century.

Direct "in situ" field evaluations have to be preferred in any case to indirect deductions from other soil characteristics measured under laboratory conditions in the same soils, or in other soils, through the so called "pedo-transfer" functions, or through the use of stochastic models such as the SCS Curve Number Method, or of other models using empirical or physical approaches, which have demonstrated to be of limited value in most of the cases.

The participants were also able to get involved with sample testing. Tutorial lectures were delivered at the school, addressing general and basic questions about nanotechnology, such as what they are, how does one go about them, what purposes can they serve. In tutorial sessions the nature of nanotechnology, the instruments of current use in its characterizations and the possible applicative uses were described at an introductory level. The first day was devoted to three sessions: Aerospace, defense, biomedicine. Electronics and mechanical properties. Materials and characterizations. The first session was opened by a lecture by J Kenny, who talked about the use of carbon nanotubes for polymer matrix nanocomposites. He reported how plasma functionalized single-walled carbon nanotubes (F-SWNTs) reacted with a primary aliphatic amine can be used for preparing an integrated nanotube composite

    Bevezetés: Krónikus hepatitis C-vírus-fertőzésben a citokineket kódoló génvariánsok szerepének kutatása az érdeklődés előterébe került. Célkitűzés: A szerzők krónikus hepatitis C-vírus-fertőzöttekben vizsgálták az IL28B-polimorfizmusok előfordulását és az egyes variánsok hatását az interferonalapú antivirális kezelés kimenetelére. Meghatározták az összefüggést az IL28B genotípusok és a betegek perifériás vérében az aktivált monocyták és lymphocyták Th1/Th2 citokin termelése között. Módszer: A genetikai tanulmányba 748 krónikus hepatitis C-vírus-fertőzött egyént vontak be. Közülük 420 beteget kezeltek pegilált interferon alfa 2a/2b injekcióval és per os ribavirinnel 24–72 héten át. A kezelés utáni követési időszak tartama 24 hét volt. A peginterferonnal és ribavirinnel kezelt betegek közül 195 (46,4%) ért el tartós virológiai választ, vagyis 24 héttel a kezelés befejezése után hepatitis C-vírus-RNS-negativitást. Kontrollként 105 egészséges egyén szolgált, normális májpróbákkal és negatív hepatitis B- és C-vírus, valamint humán immundeficientiavírus-szerológiával. Genotipizáltak még 475 egészséges roma egyént (230 férfi, 245 nő, átlagéletkor 47±8 év). Az IL28B rs12979860 polimorfizmust Custom Taqman SNP Genotyping Assays (Applied Biosystems, Life Technologies, Foster, CA, USA) segítségével határozták meg. A Th1/Th2 citokinszint-vizsgálatokhoz 40 hepatitis C-vírus-fertőzött beteg TLR-4 ligand lipopoliszacharidával aktivált perifériás vér monocytáinak, valamint PMA+Ionomycin stimulált lymphocytáinak tumornekrózis-faktor-α-, interleukin-2-, interferon-γ-, interleukin-2- és interleukin-4-termelését mérték a sejtek felülúszójában FACS-CBA, Becton–Dickinson-teszttel. Eredmények: Az IL28B rs12979860 CC genotípus hepatitis C-vírus-fertőzött betegekben kisebb gyakorisággal fordult elő, mint a kontrollban (26,1% vs. 51

    published by Plenum Press in 1990, are still a classic in surface science, and we often refer to them as the 'red book' by the colour of its cover reminiscent of another more famous book. But I do not wish to dwell upon pleasant memories of my relationship with Virginio Bortolani any longer. We should better record a few important facts of his broad activity. J P Toennies will outline Bortolani's achievements in the field of surface phonons and vibrations in a review article of this volume. So I would like to stress other very important contributions of his to the scientific development in this country and to the international community. In the late seventies surface physics was being studied by very few and tiny groups in Italy (mainly at Genova, Milano and Roma Universities). But Bortolani was able to form the first theoretical group of international reputation in this field in Italy at Modena University. In this respect he was surely helped by his previous experience at the Cavendish Laboratory working with V Heine on the theory of pseudopotentials and with N Mott. This allowed him to be at the forefront of condensed matter theory so that to propose and carry out exciting research subjects. Bortolani also supervised all the initiatives in the 70s and 80s from which Modena has grown so much as to be now considered an internationally recognized centre of surface science and nanotechnology. Second, by organizing a conference in Modena every year the week before Christmas (the so-called Congressino di Modena by the Italian participants), he promoted the diffusion of surface physics in the country: it became soon traditional for bright young physicists to come to Modena on that occasion, and, because of the exciting and friendly atmosphere, to turn to surface investigations. The catalysing activity of Bortolani is also confirmed by the number of his students who have matured into excellent scientists or technologists: Carlo Calandra, Carlo Maria Bertoni, Franca Manghi

      glasses. The main conclusion was: the indentation test provides good means to study the elasto-plastic behaviour of these materials as well as a relevant tool to subject them to multiaxial loadings. The influence of changes in local ordering of precursor melt on the formation of amorphous state and subsequent crystallization was a subject of a report presented by P Švec (Institute of Physics, Bratislava). The effect was shown for rapidly quenched Fe-Mo-B system with addition of Cu and substitution of Fe by Co prepared under varying conditions of planar flow casting and using master alloys with specific melt treatment. About 320 abstracts were received and 180 manuscripts were finally submitted for publication. All the papers followed invited lectures and full-scale oral reports were sent to the Journal of Physics: Condensed Matter for publication in a special issue. These papers will be published according to the current standard practices, policies and procedures of the Journal. All the papers following brief oral reports and posters were collected for this volume of Journal of Physics: Conference Series. All of them were edited by editors from Ekaterinburg. The Journal will provide access to all of the accepted papers free of charge via its web server. Afterwards, to publish and ship hardcopies of both the journals (Journal of Physics: Condensed Matter and Journal of Physics: Conference Series) and CDs containing all Conference papers. It was decided during the joint meeting of both the International Advisory Board and International Program Committee that the next conference in the LAM series, LAM14, will be arranged by the groups of A Di Cicco, Camerino University, and T Scopigno, University Roma `La Sapienza', in Rome, Italy. It is not an easy task to comment on new scientific tendencies in the field of liquid and amorphous alloys just after the conference. It takes one or two years to estimate the significance of the event. Only one conclusion is obvious: the LAM13

      the low altitudes (3-5 meters) will help geophysical cover all the studied area with a regular observation step (Eppelbaum, 2008). At the final step all these measurements (including results of the previous works) could be compiled to 4D models of different geophysical parameters (Eppelbaum and Ben-Avraham, 2002; Eppelbaum et al., 2010). Analysis of temperature field in the boreholes drilled in the vicinity of the studied site will permit to estimate the temperature (e.g., Eppelbaum et al., 2006c) in the historical period when this artifact was constructed and, correspondingly, utilize this characteristic for investigation of mechanical and other properties of the ancient building material. Studying of temporal variations of magnetic (e.g., Finkelstein and Eppelbaum) and VLF fields can be also used for determination of nature of some buried ancient remains. The geophysical investigations must be combined with geochemical, paleostructural, paleobiogeographical, paleomorphological and other methods (Eppelbaum et al., 2010). Application of informational parameters (Khesin et al., 1996; Eppelbaum et al., 2003b) will permit to present all available data by the use of integral convolution units.

      reconstruction and trigger of jets, missing transverse energy, electrons, photons, and taus. Pile-up, anomalous signals, and noise mitigation techniques were also discussed in the conference. On the last day, several future R&D initiatives were presented: highly granular CALICE with different technology options and plans for the dual-readout DREAM projects were the main topics. Although these approaches are quite different conceptually, future experiments will certainly benefit from their innovations. Concluding remarks by the chair of the organizing committee, Nural Akchurin (TTU), summarized the highlights of the conference and invited proposals to host the CALOR2014 conference in Europe, as the conference venue rotates between the Americas, Europe, and Asia every two years. We strived hard to keep the cost of this conference as low as possible without sacrificing the scientific mission. I am delighted to report that we were able to provide support for six junior colleagues to participate in this conference. I am also grateful to the institutions, industrial partners, and agencies that provided the support that made a lot possible: Texas Tech University, the University of New Mexico, Los Alamos National Laboratory, the US Department of Energy, CAEN, and the Wiener Plein & Baus, Corp. I also would like to thank the session conveners who organized sessions and reviewed the papers. The members of the local organizing committee were instrumental to the success of this conference: their experience and attention to detail were invaluable. Most of all, I extend my appreciation to the conference participants and to all my other colleagues who continue to enrich the field of calorimetry through their hard work and creativity. The future is bright.

[3]: While it is apparent that some mass is transferred from the Planetary Nebulae to the stars, the details of this process are not clear. It may have happened before the stars here observed were formed, or later. In the latter case, the accretion may have occurred only during a particular evolutionary phase, some 100 million years after the cluster formed, i.e. about 11 to 15 billion years ago, and in very dense environments. Moreover, the accretion rate will depend on the relative velocities: only stars that move slowly with respect to the interstellar medium has a good chance of accreting matter. This may also be (part of) an explanation of the observed, large differences from star to star.

Precise atomic parity nonconservation measurements are inherently difficult due to the fact that extremely weak signals must be detected. By scanning a probe beam across a resonance condition and then detecting the MOT fluorescence, the authors were able to monitor the population transfer from the ground level and the first excited level in the MOT. The significance of this work is that it presents a rapid and flexible method to detect the number of trapped atoms in conditions where very low numbers of these atoms are present. Such high precision measurements are essential in nuclear physics and are fundamental to our understanding of nuclear decay processes. We have selected this article for the Best Paper Award because the measurement technique demonstrated is not only innovative, but also flexible to implement as it is wavelength independent and presents a high signal to noise ratio. The experimental configuration was also extremely well documented in the paper, including a detailed estimate of the detection limits. Data were presented for many different excitation mechanisms to show the wide applicability of the measurement technique. It is expected that this
