Preference for sons: past and present.  

PubMed

This brief article discusses the present and past preference for sons in China. The preference for sons is rooted in feudal views that men are superior to women. Preference for sons dates back to the Warring States Period, in about 500 B.C. Clan brotherhoods of men have existed for centuries. Historical records mention the practice of female infanticide. Patriarchal families believed that women were economically dependent on men and thus became their subjects. Daughters married, lived in their husband's home, and did not carry the responsibility of caring for their own parents. Couples with only daughters would seek a son-in-law to support them in old age. Rural families with no sons were looked down upon. Sons were expected to carry on the family lineage, increase the reputation of the family, and protect the family's interests. The lack of sons was a sign of humiliation and a curse. The founding of the People's Republic of China brought changes to son preference. The government attempted to increase women's status. In rural areas, women were given equal access to the land. Job opportunities were created for women during the industrialization drive. The Chinese government encouraged the repudiation of the negative impacts of the doctrines of Confucius and Mencius. Efforts were made to give men and women equal pay for equal work. Legislation was passed prohibiting arranged marriage, polygyny, and early marriage. A side effect of fertility decline is the renewed preference for sons. In Huangyan and Haining in Zhejiang, a developed province, the sex ratio at birth is normal. Sexual division of labor reinforces son preference. PMID:12293427

Selecting sex: the effect of preferring sons.  

PubMed

Son preference remains common in countries from East Asia through South Asia to the Middle East and North Africa. Where sex selective technology and abortion are readily available, such as in China, South Korea and India, this has led to a marked excess in male births. Worst excesses are seen in parts of rural China where there are 140 male births for every 100 female. This leads to large numbers of unmarriageable men. Concerns about the consequences centre around the propensity to aggression and violence of these men with increased levels of crime and antisocial behaviour, threatening societal stability and security. But recent studies do not support these assumptions, but rather suggest that these men are marginalised, lonely, withdrawn and prone to psychological problems. Measures to reduce sex selection should include enforcement of existing legislation on sex-selection, and public awareness campaigns about the dangers of late abortion and gender imbalance.

Familial lambdoid craniosynostosis between father and son.  

PubMed

Lambdoid craniosynostosis is an uncommon condition, with an incidence of 1 per 33,000 live births. Its etiopathology remains controversial. Although many forms of syndromic and nonsyndromic craniosynostosis demonstrate an inherited pattern, few articles have reported lambdoid craniosynostosis in the same family. In this article, we report lambdoid synostosis in a father and son. A case review is performed. A full-term male infant was delivered by cesarean delivery because of failure to progress. He presented at 3 years of age with right unilateral lambdoid craniosynostosis with facial asymmetry and lateral deviation of his jaw, with occlusal abnormality. At presentation, the father reported skull surgery during his infancy for unilateral lambdoid craniosynostosis. Review of the computed tomographic scan of the child demonstrated a plagiocephalic appearance of the calvarium with frontal bossing and a fusion of the lambdoid suture on the right sides. The brain parenchyma showed no abnormality. The review of his father's surgical record from 33 years ago and of his computed tomographic scan ordered by our team confirmed the diagnosis of previous lambdoid craniosynostosis. Only 2 previous cases of familial isolated lambdoid craniosynostosis have been previously described in literature. Although the genetic basis has been established for many types of craniosynostosis, the etiopathogenesis of isolated lambdoid synostosis has not yet been established. We report the third case of inherited unilateral lambdoid craniosynostosis. The genetic pathogenesis of lambdoid craniosynostosis will be discussed. PMID:18520419

The image displays three bands of the reflected visible and infrared wavelength region, with a spatial resolution of 15 m. McCarran International Airport to the south and Nellis Air Force Base to the NE are the two major airports visible. Golf courses appear as bright red areas of worms. The first settlement in Las Vegas (which is Spanish for The Meadows) was recorded back in the early 1850s when the Mormon church, headed by Brigham Young, sent a mission of 30 men to construct a fort and teach agriculture to the Indians. Las Vegas became a city in 1905 when the railroad announced this city was to be a major division point. Prior to legalized gambling in 1931, Las Vegas was developing as an agricultural area. Las Vegas' fame as a resort area became prominent after World War II. The image is located at 36.1 degrees north latitude and 115.1 degrees west longitude.

In the works of Cervantes, one can observe a detailed knowledge of dental matters. Although some of his biographers think that this is the result of the very broad cultural knowledge of this distinguished Spanish writer, the authors of this paper think differently. Having studied and analyzed many documents referring to the Cervantes family, especially those which dealt with the strong influence the teachings of Cervantes' father had on his son, we have reached the conclusion that his father must have been a 16th Century dentist.

We report a familial case of acrogeria in a mother and son, with characteristic cutaneous involvement and no clinical signs of vascular Ehlers-Danlos syndrome (former EDS type IV) in spite of some tendency to bruising. The biochemical and molecular studies did not disclose any abnormality of collagen type III, which favours the diagnosis of acrogeria. It appears that recognition of acrogeria as an entity is of clinical significance since these cases are not associated with systemic involvement, and specifically with rupture of vessels and internal organs, occasionnally occurring in EDS.

Helium solubility in SON68 nuclear waste glass  

SciTech Connect

Helium behavior in a sodium borosilicate glass (SON68) dedicated to the immobilization of high-level nuclear waste is examined. Two experimental approaches on nonradioactive glass specimens are implemented: pressurized helium infusion experiments and {sup 3}He ion implantation experiments. The temperature variation of helium solubility in SON68 glass was determined and analyzed with the harmonic oscillator model to determine values of the energy of interaction E(0) at the host sites (about -4000 J/mol), the vibration frequency (about 1.7 x 10{sup 11} s{sup -1}), and the density of solubility sites (2.2 x 10{sup 21} sites cm{sup -3}). The implantation experiments show that a non diffusive transport phenomenon (i.e., athermal diffusion) is involved in the material when the helium concentration exceeds 2.3 x 10{sup 21} He cm{sup -3}, and thus probably as soon as it exceeds the density of solubility sites accessible to helium in the glass. We propose that this transport mechanism could be associated with the relaxation of the stress gradient induced by the implanted helium profile, which is favored by the glass damage. Microstructural characterization by TEM and ESEM of glass specimens implanted with high helium concentrations showed a homogeneous microstructure free of bubbles, pores, or cracking at a scale of 10 nm.

The Effect of Parents Attitudes on Sons Marriage Timing  

PubMed Central

Theories of family stability and change, demographic processes, and social psychological influences on behavior all posit that parental attitudes and beliefs are a key influence on their children抯 behavior. Though we have evidence of these effects in Western populations, there is little information regarding this social mechanism in non-Western contexts. Furthermore, comparisons of mothers and fathers independent roles in these crucial intergenerational mechanisms are rare. This paper uses measures from a ten-year family panel study featuring independent interviews with both mothers and fathers in rural Nepal to investigate these issues. We test the association of specific attitudes, rather than broad ideational domains, about childbearing and old-age care with sons subsequent marriage behavior. Our results indicate that both mothers and fathers attitudes have important and independent influences on sons marriage behavior. Simultaneous study of both parents attitudes reveals that gender-specific parenting contexts can shape the relationship between parental attitudes and children抯 behaviors. This crucial mechanism of intergenerational continuity and change is strong in this non-Western setting, with substantial implications for studies of intergenerational influences on behavior in all settings.

Becoming the Parent of a GLB Son or Daughter  

PubMed Central

Recent research has documented the importance of parental reactions to disclosure for sexual minority youth (SMY) (e.g., Ryan, Huebner, Diaz, & Sanchez, 2009). The purpose of this study was to develop a deeper understanding of the parent perspective of the disclosure to family experience of SMY ages 14-21. In-depth interviews were conducted with eight parents in the United States who had experienced a child disclose their lesbian, gay, or bisexual (LGB) orientation to them. Constructivist grounded theory and symbolic interaction theory informed the methodology and data analysis for the project. Analysis revealed that the process of becoming the parent of an LGB son or daughter is an appropriate narrative to conceptualize the parental experience of the disclosure to family process. The findings highlight how disclosure introduces new roles into the existing family system, which affects the consideration and interpretation of the salience of particular identities, such as being the parent of an LGB son or daughter. Understanding how parents experience the disclosure to family process - particularly, how they understand and re-envision the meaning of being a parent - is crucial for research and intervention to help families become supportive of SMY. Limitations and suggestions for future research are presented.

Neogene sequence stratigraphy, Nam Con Son Basin, offshore Vietnam  

SciTech Connect

An integrated well log, biostratigraphic, and seismic stratigraphic study of Miocene to Recent deltaic sediments deposited in the Nam Con Son Basin offshore from southern Vietnam shows the influence of eustacy and tectonics on sequence development. Sediments consist of Oligocene non-marine rift-basin fill (Cau Formation), early to middle Miocene tide-dominated delta plain to delta front sediments (TB 1.5 to TB 2.5, Due and Thong Formations), and late Miocene to Recent marine shelf sediments (TB. 2.6 to TB 3.1 0, Mang Cau, Nam Con Son, and Bien Dong Formations). Eustacy controlled the timing of key surfaces and sand distribution in the tectonically-quiet early Miocene. Tectonic effects on middle to late Miocene sequence development consist of thick transgressive systems tracts due to basin-wide subsidence and transgression, sand distribution in the basin center, and carbonate sedimentation on isolated fault blocks within the basin. Third-order sequence boundaries (SB) are identified by spore peaks, sand stacking patterns, and channel incision.

Neogene sequence stratigraphy, Nam Con Son Basin, offshore Vietnam  

SciTech Connect

An integrated well log, biostratigraphic, and seismic stratigraphic study of Miocene to Recent deltaic sediments deposited in the Nam Con Son Basin offshore from southern Vietnam shows the influence of eustacy and tectonics on sequence development. Sediments consist of Oligocene non-marine rift-basin fill (Cau Formation), early to middle Miocene tide-dominated delta plain to delta front sediments (TB 1.5 to TB 2.5, Due and Thong Formations), and late Miocene to Recent marine shelf sediments (TB. 2.6 to TB 3.1 0, Mang Cau, Nam Con Son, and Bien Dong Formations). Eustacy controlled the timing of key surfaces and sand distribution in the tectonically-quiet early Miocene. Tectonic effects on middle to late Miocene sequence development consist of thick transgressive systems tracts due to basin-wide subsidence and transgression, sand distribution in the basin center, and carbonate sedimentation on isolated fault blocks within the basin. Third-order sequence boundaries (SB) are identified by spore peaks, sand stacking patterns, and channel incision. In the basin center, widespread shale beds with coal occur above sequence boundaries followed by transgressive sandstone units. These TST sandstones merge toward the basin margin where they lie on older HST sandstones. Maximum flooding surfaces (MFS) have abundant marine microfossils and mangrove pollen, a change in sand stacking pattern, and often a strong seismic reflection with downlap. Fourth-order genetic-type sequences are also interpreted. The MFS is the easiest marker to identify and correlate on well logs. Fourth-order SB occur within these genetic units but are harder to identify and correlate.

Sex preference and the value of sons and daughters in Nepal.  

PubMed

Sex preference and the specific value of sons and daughters to parents in Nepal are examined using rural and urban survey data from 1979. Ideal family size among all respondents was, on average, three children, with two sons and one daughter the preferred sex composition for about 90 percent of all respondents. Among those who reported current contraceptive use, the mean number of living sons was higher than the mean number of living daughters for all respondents. Most couples have at least one son before they adopt contraception; respondents had, on average, three to four births before adopting contraception. Sons are preferred to daughters by Nepalese parents mainly for socioeconomic and religious reasons, as opposed to the economic reasons reported elsewhere in many developing societies. The findings indicate that the economic motive for having both sons and daughters may be weakening in Nepal, but that a preference for sons does exist. PMID:3406965

SysSon: A Sonification Platform for Climate Data  

NASA Astrophysics Data System (ADS)

Climate data provide a challenging working basis for sonification. Both model data and measured data are assessed in collaboration with the Wegener Center for Climate and Global Change. The multi dimensionality and multi variety of climate data has a great potential for auditory displays. Furthermore, there is consensus on global climate change and the necessity of intensified climate research today in the scientific community and general public. Sonification provides a new means to communicate scientific results and inform a wider audience. SysSon is a user centered auditory platform for climate scientists to analyze data. It gives scientists broader insights by extracting hidden patterns and features from data that is not possible using a single modal visual interface. A variety of soundscapes to chose from lessens the fatigue that comes with repeated and sustained listening to long streams of data. Initial needs assessments and user tests made the work procedures and the terminology of climate scientists clear and informed the architecture of our system. Furthermore, experiments evaluated the sound design which led to a more advanced soundscape and improvement of the auditory display. We present a novel interactive sonification tool which combines a workspace for the scientists with a development environment for sonification models. The tool runs on different operating systems and is released as open source. In the standalone desktop application, multiple data sources can be imported, navigated and manipulated either via text or a graphical interface, including traditional plotting facilities. Sound models are built from unit generator graphs which are enhanced with matrix manipulation functions. They allow us to systematically experiment with elements known from the visual domain, such as range selections, scaling, thresholding, markers and labels. The models are organized in an extensible library, from which the user can choose and parametrize. Importance is given to the persistence of all configurations, in order to faithfully reproduce sonification instances. Finally, the platform is prepared to allow the composition of interactive sound installations, transitioning between the scientific lab and the gallery space.

Maternal pre-pregnancy body mass index and pubertal development among sons.  

PubMed

Maternal overweight and obesity in pregnancy has been associated with earlier age of menarche in daughters as well as reduced semen quality in sons. We aimed at investigating pubertal development in sons born by mothers with a high body mass index (BMI). The study included 2522 sons of mothers that during pregnancy in 1984-1987 were enrolled in a mother-child cohort and gave information on their pre-pregnancy height and weight from which we calculated their BMI. Information on sons' pubertal development, assessed by age when starting regular shaving, voice break, acne and first nocturnal emission, was obtained from web-based questionnaires in 2005, when sons were 18-21 years old. Multiple linear regression analyses showed that sons of obese mothers on average started to shave regularly 8.3 (95% confidence interval: 2.5-14.0) months earlier than sons of normal weight mothers. For the three other indicators of pubertal development, results also indicated earlier pubertal development among sons of obese mothers. After excluding sons of underweight mothers in a subanalysis, we observed an inverse trend between maternal pre-pregnancy BMI and age at regular shaving, acne and first nocturnal emission. In conclusion, maternal pre-pregnant obesity may be related to earlier timing of pubertal milestones among sons. More research, preferably based on prospectively collected information about pubertal development, is needed to draw firm conclusions. PMID:24339440

SON68 glass dissolution driven by magnesium silicate precipitation  

NASA Astrophysics Data System (ADS)

Experimental results are reported on the effect of magnesium silicate precipitation on the mechanisms and rate of borosilicate glass dissolution. Leaching experiments with SON68 glass, a borosilicate containing no Mg, were carried out in initially deionized water at 50 癈 with a glass-surface-area-to-solution-volume ratio of 20,000 m-1. After 29 days of alteration the experimental conditions were modified by the addition of Mg to trigger the precipitation of Mg-silicate. Additional experiments were conducted to investigate the importance of other parameters such as pH or dissolved silica on the mechanisms of precipitation of Mg-silicates and their consequences on the glass dissolution rate. Mg-silicates precipitate immediately after Mg is added. The amount of altered glass increases with the quantity of added Mg, and is smaller when silicon is added in solution. A time lag is observed between the addition of magnesium and the resumption of glass alteration because silicon is first provided by partial dissolution of the previously formed alteration gel. It is shown that nucleation does not limit Mg-silicate precipitation. A pH above 8 is necessary for the phase to precipitate under the investigated experimental conditions. On the other hand the glass alteration kinetics limits the precipitation if the magnesium is supplied in solution at a non-limiting rate. The concentration of i in solution was analyzed as well as that of boron. The quantity of i released from the glass is estimated with the assumption that i and B are released congruently at the glass dissolution front. The remained quantity of the element i is then supposed to be in the gel or in the secondary phase. In this paper, we do not make a difference between gel and hydrated glass using the same word 'gel' whereas Gin et al. [40] makes this difference. Recent papers [40,41] discussed about different key issues related to the passivation properties of the alteration layer including the hydrated glass layer at the interface with the pristine glass, the gel and the secondary phases. B is not fixed in the gel layer but retention of both B and Li retention is evidenced in one part of the hydrated layer corresponding to a narrow interdiffusion layer [40]. The (H/Li) interdiffusion coefficient decreases by several orders of magnitude when the alteration solution is silica-saturated [41]. This interdiffusion coefficient is a relevant parameter for evaluating the passivation phenomenon. It has also been shown that the nanoporosity of the hydrated glass layer plays an important role [40]. It can be deduced that the precipitation of a silicate secondary phase associated with the consumption of silica strongly affects the hydration rate of the glass and as a consequence its alteration. So the precipitation of secondary phase is a motive force which modifies the physico-chemical properties of the reactive interface situated in the gel or probably in the hydrated glass which has a role of passivation. Currently, the notion of reactive interface and its physico-chemical conditions are under investigations. In our study, solid characterizations are difficult so we use only the general notion of a protective gel. The increased calcium concentrations correspond to congruent dissolution of the gel formed before the addition of magnesium. The Ca/Si molar ratio of the gel was estimated from each experiment based on the data for day 29; in each case the ratio was near 0.1. This hypothesis was not taken into account for the experiment with regular Mg additions because no gel alteration occurred between 45 and 63 days. Glass alteration released boron and silicon in the same proportions as in the glass. No gel formation occurred within the balance period except in the experiment with 100 mg L-1 of Mg at t = 0, for which the cases of 10%, 30% and 50% gel formation (percentage of silicon from glass alteration incorporated in the gel) are indicated as examples. Based on the calcium concentrations in solution for the experiment with 100 mg L-1 of Mg at t = 0, the most representative cas

Both instruments perform Doppler shift velocity measurements in integrated sunlight, although BiSON perform measurements from the two wings of potassium absorption line and GOLF from one wing of the NaD1 line. Discrepancies between the two datasets have been observed. We show,in fact, that the relative power depends on the wing in which GOLF data observes. During the blue wing period, the relative power is mugh higher than in BiSON datasets, while a good agreement has been observed during the red period.

Parent-son decision-making about human papillomavirus vaccination: a qualitative analysis  

PubMed Central

Background Licensed for use in males in 2009, Human Papillomavirus (HPV) vaccination rates in adolescent males are extremely low. Literature on HPV vaccination focuses on females, adult males, or parents of adolescent males, without including adolescent males or the dynamics of the parent-son interaction that may influence vaccine decision-making. The purpose of this paper is to examine the decision-making process of parent-son dyads when deciding whether or not to get vaccinated against HPV. Methods Twenty-one adolescent males (ages 1317), with no previous HPV vaccination, and their parents/guardians were recruited from adolescent primary care clinics serving low to middle income families in a large Midwestern city. Dyad members participated in separate semi-structured interviews assessing the relative role of the parent and son in the decision regarding HPV vaccination. Interviews were recorded, transcribed, and coded using inductive content analysis. Results Parents and sons focused on protection as a reason for vaccination; parents felt a need to protect their child, while sons wanted to protect their own health. Parents and sons commonly misinterpreted the information about the vaccine. Sons were concerned about an injection in the penis, while some parents and sons thought the vaccine would protect them against other sexually transmitted infections including Herpes, Gonorrhea, and HIV. Parents and sons recalled that the vaccine prevented genital warts rather than cancer. The vaccine decision-making process was rapid and dynamic, including an initial reaction to the recommendation for HPV vaccine, discussion between parent and son, and the final vaccine decision. Provider input was weighed in instances of initial disagreement. Many boys felt that this was the first health care decision that they had been involved in. Dyads which reported shared decision-making were more likely to openly communicate about sexual issues than those that agreed the son made the decision. Conclusion Parents and sons play an active role in the decision-making process, with an individual抯 role being influenced by many factors. The results of this study may be used to guide the messages presented by clinicians when recommending the HPV vaccine, and future vaccine uptake interventions. PMID:23241217

SON is a spliceosome-associated factor required for mitotic progression  

PubMed Central

The eukaryotic RNA splicing machinery is dedicated to the daunting task of excising intronic sequences on the many nascent RNA transcripts in a cell, and in doing so facilitates proper translation of its transcriptome. Notably, emerging evidence suggests that RNA splicing may also play direct roles in maintaining genome stability. Here we report the identification of the RNA/DNA-binding protein SON as a component of spliceosome that plays pleiotropic roles during mitotic progression. We found that SON is essential for cell proliferation, and that its inactivation triggers a MAD2-dependent mitotic delay. Moreover, SON deficiency is accompanied by defective chromosome congression, compromised chromosome segregation and cytokinesis, which in turn contributes to cellular aneuploidy and cell death. In summary, our study uncovers a specific link between SON and mitosis, and highlights the potential of RNA processing as additional regulatory mechanisms that govern cell proliferation and division.

Parents and Sons Beliefs in Sexual Disinhibition After Human Papillomavirus Vaccination  

PubMed Central

Background The concern that adolescent girls who receive human papillomavirus (HPV) vaccine may be more likely to have sex (ie, sexual disinhibition) has been commonplace in media coverage, but this belief is not held by many parents of adolescent girls. Because no studies have addressed this topic for adolescent boys, we examined parents and their adolescent sons beliefs in sexual disinhibition occurring after boys receive HPV vaccine. Methods A national sample of parents of adolescent boys (n = 547) and their sons (aged 1517 years; n = 176) completed online surveys in fall 2010. We used multi-item scales to measure parents and sons beliefs in sexual disinhibition after HPV vaccination. We used multivariate linear regression to identify correlates of beliefs in sexual disinhibition. Results Less than a quarter of parents or sons agreed with statements suggesting that HPV vaccination leads to sexual disinhibition among adolescent boys (range, 20%24%). Parents who had more liberal political affiliations (? = ?0.11), had a daughter who had received HPV vaccine (? = ?0.12), or had no daughter (? = ?0.10) reported weaker beliefs in sexual disinhibition. Parents who reported higher anticipated regret if their sons got HPV vaccine and fainted (? = 0.18) indicated stronger beliefs in sexual disinhibition. Sons who perceived higher peer acceptance of HPV vaccination (? = 0.44) or were Hispanic (? = 0.21) had stronger beliefs in sexual disinhibition. Conclusions Most parents and sons did not believe that HPV vaccination leads to sexual disinhibition among boys. Understanding the characteristics of parents and sons who hold these beliefs may help inform efforts to increase HPV vaccine uptake among boys. PMID:24275737

Becoming a back-up carer: Parenting sons with Duchenne muscular dystrophy transitioning into adulthood.  

PubMed

The population of adults with Duchenne muscular dystrophy is increasing rapidly. However, information for individuals with DMD and their parents about the transition to adulthood is lacking; young adult sons and their parents may struggle to maintain smooth family functioning and well-being during this period. This study examined the process of change in parental behaviors during their son's transition. The participants were 18 parents with sons aged 15-30 years. Data were obtained from semi-structured interviews and analyzed using a grounded theory approach. Eleven categories of behaviors were identified across three domains: emotional, physical, and determination. The changes made by parents were directed toward becoming a back-up carer: letting go of some control but still being active participants in their sons' lives. We identified several issues important for well-being in the transition period: psychological support, the aging of the parents (the primary caregivers) and the concomitant emergency and specialized care needs, and parents' intervention in the self-determination of adult sons with DMD. The findings of this study may provide a rationale to advocate for policies to improve support for parents of sons with DMD transitioning to adulthood and provide information to help parents in their role as primary care providers.

History of son preference and sex selection in India and in the west.  

PubMed

In the history of mankind, there was a time when women dominated the world. In due course of time, as the patriarchal societies evolved, the status of women gradually declined. Sons were preferred to daughters. In India, the Brahmin community promoted such customs and rituals, which gave more and more importance to sons eg. Lighting the funeral pyre of the father was told to be a pre-condition for salvation of his spirit. Similarly, in western civilization also women were considered to be weak. In consonance with such a mind-set man has been trying various techniques for sex-selection since antiquity eg. for acquiring a son choosing a special day, time and posture for sexual intercourse, special diet, charms and amulet and prayers etc. In Vedas also punsavana karma has been described as a technique for acquiring a son. Apart from these techniques, female infanticide has also been used as a way to create a male dominated, son-worshipping society. On development of the technique of ultrasonography as an example of progress of science and technology, man has devised a new way of killing females in womb itself, which has resulted in continuous decline in female: male sex ratio in India. To stop this, Indian Govt. promulgated PNDT Act 1994. But considering the widely prevalent practice of use of various regimen of sex-pre-selection by people as well as unscrupulous medical practitioners, Govt. of India has amended this Act (2002). Still, as authors have found in one of their studies, sex-selection drugs are being used widely by north Indians for getting a son. Here, it should be noted that sex-selection methods are being used in west also. But the perspective is different. There, it is not used for female feticide or for acquiring a son. Rather, it is more an effort towards demonstrating the control of man over the NATURE. PMID:17154116

Las Vegas Strip History  

NSDL National Science Digital Library

Created by amateur cultural historian Deanna DeMatteo, this site offers "the most detailed history of the Las Vegas Strip on the Internet today," showing in words and graphics the evolution of the properties on the Strip from its beginning to the present. Drawing on materials provided by publications, professional Las Vegas historians, and the Nevada State Museum and Historical Society, DeMatteo offers a detailed, noncommercial history with plenty of photographs (many archival) of the strip from the first night club in 1930 named Pair O Dice to the first true casino hotel, El Rancho with 63 rooms in 1941, to Hilton's giant Paris Las Vegas opening earlier this Fall with 2,914 rooms. There is also a special topics section, covering people significant in the strip's development, such as Warren "Doc" Bayley and Howard Hughes. Launched in August, the Website is continually updated with new material. Note: to reach table of contents, click on the photograph at end of the homepage.

Having a Son or Daughter with Down Syndrome: Perspectives from Mothers and Fathers  

PubMed Central

This study asks parents who have children with Down syndrome how they feel about their lives so that such information could be shared with expectant couples during prenatal counseling sessions. A valid and reliable survey instrument was mailed to 4,924 households on the mailing lists of six non-profit Down syndrome organizations. Of the 2,044 respondents, 99% reported that they love their son or daughter; 97% were proud of them; 79% felt their outlook on life was more positive because of them; 5% felt embarrassed by them; and 4% regretted having them. The parents report that 95% of their sons or daughters without Down syndrome have good relationships with their siblings with Down syndrome. The overwhelming majority of parents surveyed report that they are happy with their decision to have their child with Down syndrome and indicate that their sons and daughters are great sources of love and pride.

Youngest Toba Tuff in the Son Valley, India: a weak and discontinuous stratigraphic marker  

NASA Astrophysics Data System (ADS)

Investigation of the climatic and environmental impacts of the Youngest Toba Tuff (YTT, 74 ka BP) eruption of Toba volcano, Sumatra, is crucial for understanding the consequences of the eruption for contemporaneous human populations. The Middle Son Valley, in India, was the first locality on the Indian subcontinent where the YTT was reported. The ash bed forms a discontinuous layer stretching for over 30 km along the river. Here we report on the stratigraphic contexts of YTT ash layers in alluvial deposits of the Middle Son Valley, in order to reconstruct the taphonomy of the ash deposits and the dynamic of their deposition. Although the distal ash has been studied since the 1980s, its stratigraphic integrity and the mechanisms and pathways involved in its transport and deposition have bit previously been assessed. We find that the YTT occurrences in the Middle Son Valley may not be reliable chronostratigraphical markers for millennial scale palaeoenvironmental reconstruction.

Son and daughter preferences in Benighat, Nepal: implications for fertility transition.  

PubMed

Married women in Benighat, Nepal stressed old age security and continuity of lineage as prominent reasons for wanting sons. In addition, women clearly desired daughters too--an important finding that is less often stressed. Religious reasons and help with household chores were the most common reasons reported for wanting a daughter. Strong desires for sons could increase fertility in settings where fertility is controlled. Additional desires for daughters could have an additional pronatalist influence. For Benighat we document a pervasive desire for at least two sons and at least one daughter. If realized, these sex composition preferences would increase fertility by 50 per cent. Actual effects are no doubt smaller, but the effects of sex preference on the desire for more children and on contraceptive use are clearly visible. PMID:8738551

Vaccinating Sons against HPV: Results from a U.S. National Survey of Parents  

PubMed Central

Purpose The quadrivalent HPV vaccination was approved for use in males ages 9 to 26 in 2009 and recommended for routine administration in 2011. The purpose of this study was to uncover predictable commonalities amongst parents who chose to vaccinate their 1117 year old sons against HPV. Methods We compiled data from a U.S. national sample of 779 parents with sons 1117 years old using a web-based survey to gather information about behavioral and sociodemographic factors which predicted receipt of 1 or more HPV vaccine doses based on parental report. Predictors were first modeled individually for univariable associations. Significant predictors (p<0.10) were combined in a multivariable model. Results In the adjusted model, independent predictors included receipt of flu vaccination, health insurance coverage and sexual health topic discussions with sons. Sons who had received a flu shot in the last two years more frequently received at least one dose of the vaccine (OR 1.82; 95% CI 1.452.26). Sons covered by private health insurance had decreased odds of HPV vaccination (OR 0.56 95% CI 0.370.83). Lastly, parents who had discussed sexual health topics with their sons were more likely to vaccinate (OR 1.61; 95% CI 1.371.89). Conclusions Male vaccination rates in the U.S. have increased, but males continue to be under-immunized. Utilization of health care is an important factor in HPV vaccine uptake; therefore, health care providers should use every contact as an opportunity to vaccinate. Communication about sexual health topics may provide a forum for parents and health care providers to have conversations about HPV vaccination as those more comfortable discussing these topics may also be more comfortable discussing HPV vaccination.

History: Las Vegas  

NSDL National Science Digital Library

Las Vegas (or "The Meadows" in Spanish) is a curious place, and it is not much of a stretch to say that it was transformed from a sleepy railroad town into a ring-a-ding swinging town in just a few decades during the 20th century. The Las Vegas Sun has gone above and beyond the call of duty by crafting a site that presents a multimedia-rich experience that narrates the history of this rather unique American city. Visitors should start their journey here by watching one or all eleven parts of their "Boomtown" video on the history of the town. Then visitors may want to take a look at the interactive map of the "Strip", which tells the fortunes of casinos and other buildings, past, present, and future, which have graced this notable region of mega-structures amidst the desert. After that, visitors should look at the "12 Voices from the Past" area. Voices like casino owner Benny Binion and former Nevada governor Mike O'Callaghan are featured here, and it's a great trip back through the city's varied past.

Virgin ant queens mate with their own sons to avoid failure at colony foundation.  

PubMed

Mother-son mating (oedipal mating) is practically non-existent in social Hymenoptera, as queens typically avoid inbreeding, mate only early in life and do not mate again after having begun to lay eggs. In the ant genus Cardiocondyla mating occurs among sib in the natal nests. Sex ratios are extremely female-biased and young queens face the risk of remaining without mating partners. Here, we show that virgin queens of Cardiocondyla argyrotricha produce sons from their own unfertilized eggs and later mate with them to produce female offspring from fertilized eggs. Oedipal mating may allow C. argyrotricha queens to found new colonies when no mating partners are available and thus maintains their unusual life history combining monogyny, mating in the nest, and low male production. Our result indicates that a trait that sporadically occurs in solitary haplodiploid animals may evolve also in social Hymenoptera under appropriate ecological and social conditions. PMID:24346351

Early social exposure in wild chimpanzees: Mothers with sons are more gregarious than mothers with daughters.  

PubMed

In many mammals, early social experience is critical to developing species-appropriate adult behaviors. Although mother-infant interactions play an undeniably significant role in social development, other individuals in the social milieu may also influence infant outcomes. Additionally, the social skills necessary for adult success may differ between the sexes. In chimpanzees (Pan troglodytes), adult males are more gregarious than females and rely on a suite of competitive and cooperative relationships to obtain access to females. In fission-fusion species, including humans and chimpanzees, subgroup composition is labile and individuals can vary the number of individuals with whom they associate. Thus, mothers in these species have a variety of social options. In this study, we investigated whether wild chimpanzee maternal subgrouping patterns differed based on infant sex. Our results show that mothers of sons were more gregarious than mothers of daughters; differences were especially pronounced during the first 6 mo of life, when infant behavior is unlikely to influence maternal subgrouping. Furthermore, mothers with sons spent significantly more time in parties containing males during the first 6 mo. These early differences foreshadow the well-documented sex differences in adult social behavior, and maternal gregariousness may provide sons with important observational learning experiences and social exposure early in life. The presence of these patterns in chimpanzees raises questions concerning the evolutionary history of differential social exposure and its role in shaping sex-typical behavior in humans.

The fitness of dispersing spotted hyaena sons is influenced by maternal social status.  

PubMed

Life history theory predicts that mothers should provide their offspring with a privileged upbringing if this enhances their offspring's and their own fitness. In many mammals, high-ranking mothers provide their offspring with a privileged upbringing. Whether dispersing sons gain fitness benefits during adulthood from such privileges (a 'silver spoon' effect) has rarely been examined. In this paper, we show that in the complex, female-dominated society of spotted hyaenas, high-born sons grew at higher rates, were more likely to disperse to clans offering the best fitness prospects, started reproducing earlier and had a higher reproductive value than did lower-born sons. This illustrates the evolutionary importance of maternal effects even in societies in which male size or fighting ability does not influence fitness. By demonstrating for the first time in a non-human mammal that maternal status influences immigration patterns, the study also advances our understanding of two key ecological and evolutionary processes, dispersal and habitat selection.

Men as caregivers of the elderly: support for the contributions of sons  

PubMed Central

Emerging practice research on filial sources of health care support has indicated that there is a growing trend for sons to assume some responsibility for the health care needs of their aging parents. The purpose of this work is to propose that outcomes observed through a secondary analysis of data from a previous mixed methods research project, conducted with a sample of 60 elderly women residing in independent living centers, supports this concept in elder care. The present study is a retrospective interpretation utilizing the original database to examine the new question, 揥hat specific roles do sons play in caregiving of their elderly mothers? While daughters presently continue to emerge in existing health care studies as the primary care provider, there is a significant pattern in these data for older patients to depend upon sons for a variety of instrumental activities of daily living. As the baby-boomers age, there is more of cohort trend for their families to be smaller, adult daughters to be employed, and for adult children to be more geographically mobile. These factors may combine to make health care support networks more limited for the current aging population, challenging the elderly and their health care providers to revisit the cultural gender norms that are used to identify caregivers.

Associations of mortality with own height using son's height as an instrumental variable.  

PubMed

Height is associated with mortality from many diseases, but it remains unclear whether the association is causal or due to confounding by social factors, genetic pleiotropy,(1) or existing ill-health. The authors investigated whether the association of height with mortality is causal by using a son's height as an instrumental variable (IV) for parents' height among the parents of a cohort of 1,036,963 Swedish men born between 1951 and 1980 who had their height measured at military conscription, aged around 18, between 1969 and 2001. In a two-sample IV analysis adjusting for son's age at examination and secular trends in height, as well as parental age, and socioeconomic position, the hazard ratio (HR) for all-cause paternal mortality per standard deviation (SD, 6.49cm) of height was 0.96 (95% confidence interval (CI): 0.95, 0.96). The results of IV analyses of mortality from all causes, cardiovascular disease (CVD), respiratory disease, cancer, external causes and suicide were comparable to those obtained using son's height as a simple proxy for own height and to conventional analyses of own height in the present data and elsewhere, suggesting that such conventional analyses are not substantially confounded by existing ill-health.

Son Preference and Children抯 Housework: The Case of India  

PubMed Central

We use a nationally representative survey of Indian households (NFHS-3) to conduct the first study that analyzes whether son preference is associated with girls bearing a larger burden of housework than boys. Housework is a non-negligible part of child labor in which around 60 % of children in our sample are engaged. The preference for male offspring is measured by a mother抯 ideal proportion of sons among her offspring. We show that when the ideal proportion increases from 0 to 1, the gap in the time spent on weekly housework for an average girl compared to that of a boy increases by 2.5 h. We conduct several robustness analyses. First, we estimate the main model separately by caste, religion, and family size. Second, we use a two-stage model to look at participation into housework (as well as other types of work) in addition to hours. Third, we use mother抯 fertility intentions as an alternative measure of son preference. The analysis confirms that stated differences in male preference translate in de facto differences in girl抯 treatment. PMID:23914000

Son preference and intimate partner violence victimization in India: examining the role of actual and desired family composition.  

PubMed

Son preference has been considered as a determinant of women's risk of intimate partner violence (IPV) experience in India, although quantitative evidence from large nationally representative studies testing this relationship is limited. This study examines the association between husband's son preference, sex composition of children and risk of physical and sexual IPV victimization among wives. Information was collected for 26,284 couples in the nationally representative 2005-2006 National Family Health Survey of India. The exposures were husband's son preference measured as husband's desire for one or more sons greater than the number of daughters and sex composition of the household: only sons, only daughters and mixed. Outcome included past year physical and/or sexual IPV. The results showed that husband's reported son preference (RR: 1.05; 95% CI: 0.98-1.13) and sex composition of children were not associated with risk for IPV victimization in the models adjusted for socio-demographic factors. The findings from this first population-based study of socio-cultural norms around son preference and married Indian women's risk for IPV victimization indicate that cultural preference for sons does not influence women's risk for IPV victimization.

Designing Messages to Motivate Parents to Get Their Preteenage Sons Vaccinated Against Human Papillomavirus  

PubMed Central

CONTEXT Human papillomavirus (HPV) vaccine, licensed for use in 926-year-olds, is most effective when given before sexual activity begins. HPV causes genital warts, is associated with several cancers and disproportionately affects racial and ethnic minorities. Parents are typically unaware of male HPV vaccine; messages that might motivate them to get their preteenage sons vaccinated are unexplored. METHODS Messages promoting vaccination of preteenage boys were designed and tested in 2009 and 2010. Five focus groups were conducted with 29 black parents of 1112-year-old boys, recruited through three churches and a middle school in North Carolina, and a racially diverse sample of 100 parents of 913-year-old boys in a university-based adolescent health clinic was interviewed. A constant comparison method was used to code transcripts and interpret themes. Chi-square and t tests or analyses of variance were used to assess differences in quantitative data. RESULTS Focus group parents knew little about HPV in males. Although concerned about safety and cost, parents supported vaccination for their sons. They wanted to see racial diversity and both parents in motivational materials. In interviews, 89% of parents reported never having heard of male HPV vaccine. The largest proportion said that a message stressing the prevalence and possible consequences of HPV infection was the most motivating (32%); the design favored by the largest proportion (43%) showed two parents. CONCLUSIONS Messages that may most motivate parents to get preteenage boys vaccinated against HPV focus on infection risk and include images of parents with their sons. PMID:22405151

When a son steals money from his mother: courtroom perceptions of elder financial exploitation.  

PubMed

The perception of elder financial exploitation was investigated using community members (N = 104) and undergraduates (N = 143). Participants read an exploitation trial summary; an 85-year-old victim accused her son of stealing her money. Primary results indicated that alleged victims described as healthy rendered more guilty verdicts than those described as having a cognitive deficit; pro-victim judgments were higher for women than men; and younger and older community members' rendered more guilty verdicts than middle-aged mock jurors. The results are discussed in terms of the factors that impact the perception of exploitation in court. PMID:23473296

Sons learn songs from their social fathers in a cooperatively breeding bird.  

PubMed

Song learning is hypothesized to allow social adaptation to a local song neighbourhood. Maintaining social associations is particularly important in cooperative breeders, yet vocal learning in such species has only been assessed in systems where social association was correlated with relatedness. Thus, benefits of vocal learning as a means of maintaining social associations could not be disentangled from benefits of kin recognition. We assessed genetic and cultural contributions to song in a species where social association was not strongly correlated with kinship: the cooperatively breeding, reproductively promiscuous splendid fairy-wren (Malurus splendens). We found that song characters of socially associated father-son pairs were more strongly correlated (and thus songs were more similar) than songs of father-son pairs with a genetic, but no social, association (i.e. cuckolding fathers). Song transmission was, therefore, vertical and cultural, with minimal signatures of kinship. Additionally, song characters were not correlated with several phenotypic indicators of male quality, supporting the idea that there may be a tradeoff between accurate copying of tutors and quality signalling via maximizing song performance, particularly when social and genetic relationships are decoupled. Our results lend support to the hypothesis that song learning facilitates the maintenance of social associations by permitting unrelated individuals to acquire similar signal phenotypes.

Bartonella henselae bacteremia in a mother and son potentially associated with tick exposure  

PubMed Central

Background Bartonella henselae is a zoonotic, alpha Proteobacterium, historically associated with cat scratch disease (CSD), but more recently associated with persistent bacteremia, fever of unknown origin, arthritic and neurological disorders, and bacillary angiomatosis, and peliosis hepatis in immunocompromised patients. A family from the Netherlands contacted our laboratory requesting to be included in a research study (NCSU-IRB#1960), designed to characterize Bartonella spp. bacteremia in people with extensive arthropod or animal exposure. All four family members had been exposed to tick bites in Zeeland, southwestern Netherlands. The mother and son were exhibiting symptoms including fatigue, headaches, memory loss, disorientation, peripheral neuropathic pain, striae (son only), and loss of coordination, whereas the father and daughter were healthy. Methods Each family member was tested for serological evidence of Bartonella exposure using B. vinsonii subsp. berkhoffii genotypes I-III, B. henselae and B. koehlerae indirect fluorescent antibody assays and for bacteremia using the BAPGM enrichment blood culture platform. Results The mother was seroreactive to multiple Bartonella spp. antigens and bacteremia was confirmed by PCR amplification of B. henselae DNA from blood, and from a BAPGM blood agar plate subculture isolate. The son was not seroreactive to any Bartonella sp. antigen, but B. henselae DNA was amplified from several blood and serum samples, from BAPGM enrichment blood culture, and from a cutaneous striae biopsy. The father and daughter were seronegative to all Bartonella spp. antigens, and negative for Bartonella DNA amplification. Conclusions Historically, persistent B. henselae bacteremia was not thought to occur in immunocompetent humans. To our knowledge, this study provides preliminary evidence supporting the possibility of persistent B. henselae bacteremia in immunocompetent persons from Europe. Cat or flea contact was considered an unlikely source of transmission and the mother, a physician, reported that clinical symptoms developed following tick exposure. To our knowledge, this is the first time that a B. henselae organism has been visualized in and amplified from a striae lesion. As the tick bites occurred three years prior to documentation of B. henselae bacteremia, the mode of transmission could not be determined. PMID:23587194

Haplotype and mutation analysis for newly suggested Y-STRs in Korean father-son pairs.  

PubMed

In this study, 363 Korean father-son haplotype transfers in 351 families were analyzed using an in-house multiplex PCR system for 14 Y-STRs (DYS385a/b, DYF387S1, DYS391, DYS449, DYS460, DYS481, DYS518, DYS533, DYS549, DYS570, DYS576, DYS627 and DYS643), that included 11 loci newly added to the PowerPlex Y23 system or the Yfiler Plus system. The Y-STRs showed gene diversity values ranging from 0.2499 to 0.9612; the multicopy Y-STR loci DYS385 and DYF387S1 had high gene diversity of 0.9612 and 0.9457, respectively. In addition, DYF387S1, which has two copies, showed three alleles in seven individuals, and micro-variant alleles were observed in 14 individuals at four loci (DYS448, DYS518, DYS570 and DYS627). Among 351 haplotypes for the 11 newly added Y-STRs, 350 different haplotypes were observed, with an overall haplotype diversity of 0.9999 and discrimination capacity of 99.72%. In 363 haplotype transfers from 351 pedigrees, 29 single-step mutations were observed at 11 Y-STRs. Locus-specific mutation rate estimates varied from 0.0 to 1.9310(-2), with an average estimated mutation rate of 6.6610(-3). Two father-son pairs had mutations at two different loci in 11 Y-STRs. The number of pairs with mutations at multiple loci increased to five when the mutation event was investigated for haplotype transfer at 28 Y-STRs including 17 Yfiler loci and 11 Y-STRs examined in this study: four father-son pairs had mutations at two loci, and one pair had mutations at three loci. Overall, mutations were frequently observed at DYS449, DYS576 and DYS627 loci, which are known to be rapidly mutating Y-STRs. Mutation rate estimates at most loci were not significantly different from rates in other populations, but estimates for DYF387S1, DYS518 and DYS570 were considerably lower in the Korean population than in other populations.

The prodigal son: some psychological aspects of Augustine's conversion to Christianity.  

PubMed

Augustine's conversion is considered exemplary for its Christian testimony. However, the psychological aspects are also relevant, for Augustine's conversion to Christianity was as much inspired by personal and cultural ambitions as by religious convictions. For Augustine, the conversion to the Christian faith spelled a life of asceticism--a life of celibacy, a virtuous and chaste existence, which also offered him a means of escape from the threatening ambiguity of parental relations and a chance to realize the cultural ideal of the civilized philosopher who has subjugated the passions of the flesh. In this paper we explore the psychological dynamics of the absent father, the suffering mother and the prodigal son and the role they played in Augustine's conversion to Christianity. PMID:19105003

Son preference, use of maternal health care, and infant mortality in rural China, 1989-2000.  

PubMed

This study assesses the effects of socio-economic conditions and the interaction between son preference and China's one-child family planning policy on the use of maternal health care services and their effects on infant mortality in rural China, using nationally representative data from the 2001 National Family Planning and Reproductive Health Survey. The results show that while the use of maternal health care services has continued to increase over time, large gaps still exist in the use of these services and in infant survival by mother's education, community income, and parity. Further improvements in the reproductive health of all women and in infant survival will require effective reduction of the obstacles to the use of maternal health care among those women in rural China who are less educated, poor, and of higher parity.

B Auditory brainstem potentials in sons of alcoholic fathers. Alcohol Clin Exp Res  

E-print Network

With the use of event-related brain potentials we have obsewed sensory as well as cognitive deficits in abstinent alcoholics. By recording auditory brainstem potentials (BSP) from abstinent alcoholics we demonstrated significant delays in brainstem transmission time. We have also repotted that P3 amplitudes are significantly reduced in abstinent alcoholics compared to control subjects. Although the neurophysiological deficits obsewed in abstinent alcoholics are presumed to be alcohol-related effects, it is possible that some of these deficits may exist prior to alcohol exposure, and may be present in subjects at high risk for alcoholism. We have recently obsewed significantly reduced P3 components in young sons of alcoholics similar to those obsewed in abstinent alcoholics. In the present study, we examined auditory BSPs in young boys at high risk for alcoholism and matched controls. We found no statistically significant difference in brainstem transmission time between

"Fathers" and "sons" of theories in cell physiology: the membrane theory.  

PubMed

The last 50 years in the history of life sciences are remarkable for a new important feature that looks as a great threat for their future. A profound specialization dominating in quickly developing fields of science causes a crisis of the scientific method. The essence of the method is a unity of two elements, the experimental data and the theory that explains them. To us, "fathers" of science, classically, were the creators of new ideas and theories. They were the true experts of their own theories. It is only they who have the right to say: "I am the theory". In other words, they were carriers of theories, of the theoretical knowledge. The fathers provided the necessary logical integrity to their theories, since theories in biology have still to be based on strict mathematical proofs. It is not true for sons. As a result of massive specialization, modern experts operate in very confined close spaces. They formulate particular rules far from the level of theory. The main theories of science are known to them only at the textbook level. Nowadays, nobody can say: "I am the theory". With whom, then is it possible to discuss today on a broader theoretical level? How can a classical theory--for example, the membrane one--be changed or even disproved under these conditions? How can the "sons" with their narrow education catch sight of membrane theory defects? As a result, "global" theories have few critics and control. Due to specialization, we have lost the ability to work at the experimental level of biology within the correct or appropriate theoretical context. The scientific method in its classic form is now being rapidly eroded. A good case can be made for "Membrane Theory", to which we will largely refer throughout this article. PMID:16359629

The Relationship Between Sexual Function and Quality of Sleep in Caregiving Mothers of Sons with Duchenne Muscular Dystrophy  

PubMed Central

Introduction The task of the caregiver, especially a caregiving mother of a son with a chronic and fatal disease, may interfere with their quality of sleep, sexuality, and some hormone levels. Aim The aim of this study was to evaluate the sexual function and the quality of sleep of caregiving mothers of sons with Duchenne muscular dystrophy (DMD). Methods We evaluated 20 caregiving mothers of sons with DMD and 20 caregiving mothers of sons without any neuromuscular or chronic disease. All of them voluntarily responded to the evaluating questionnaires about their sexuality and their quality of sleep, and gave blood samples to evaluate their hormonal levels. Main Outcome Measures All mothers were evaluated using the questionnaire of Female Sexual Function Index (FSFI) and the Pittsburgh questionnaire (PSQI). The blood samples were tested to determine serum levels of testosterone, estradiol, follicle-stimulating hormone, luteinizing hormone, progesterone, adrenocorticotropic hormone, and cortisol. Results Caregiving mothers of sons with DMD had significantly lower scores in the FSFI questionnaire, suggesting a higher risk for sexual dysfunction. The PSQI demonstrated that these caregiving mothers present increased sleep latency, reduced sleep efficiency, daytime dysfunction, and poor sleep quality. Blood tests showed a rise in cortisol levels, which correlated with the compromised sexuality and quality of sleep. Conclusions This study indicates that caregiving mothers of sons with DMD show major risk for sexual dysfunction and a reduction in their quality of sleep mediated in part by the hormonal changes related to stress.

Utilizando el modelo de Kemmis y McTaggart (1987) la investigacion-accion se planteo como un proceso dinamico en cuatro momentos en espiral constituidos por la planificacion, la accion, la observacion y la reflexion. Cada una de las fases tuvo una intencion retrospectiva y prospectiva formando una espiral de autorreflexion del conocimiento y la accion. Se llevaron a cabo audio grabaciones en clases y analisis de documentos. Ademas, la profesora-investigadora hizo un portafolio para reflexionar sobre las creencias de la cultura de la ciencia que tienen los estudiantes y las creencias del aprendizaje que tiene la profesora y sobre como la comprension de estos elementos ayudo a mejorar su practica educativa a traves del tiempo. Los resultados obtenidos apuntan a que las creencias de la cultura de la ciencia que tiene el grupo de estudiantes son diversas. Ellos si creen que la ciencia tiene una cultura la cual describieron como: complicada y desconocida que evoluciona constantemente, que es un conjunto de metodos, que es altamente tecnologica, que resuelve problemas de salud, ayuda a interpretar la realidad del mundo que los rodea y su origen y que existen unas intersecciones entre la ciencia y el poder. Sobre las creencias del proceso de aprendizaje de la profesora-investigadora, estas senalan que el modelaje de actores, la vision de la academia que tiene ella asi como la participacion y negociacion entre todos los involucrados en el proceso educativo, son factores que inciden en el proceso de aprendizaje.

Non-genomic transmission of paternal behaviour between fathers and sons in the monogamous and biparental California mouse.  

PubMed

Maternal behaviour has profound, long-lasting implications for the health and well-being of developing offspring. In the monogamous California mouse (Peromyscus californicus), care by both parents is critical for offspring survival. We tested the hypothesis that similar to maternal care in rodents, paternal huddling and grooming (HG) behaviour can be transmitted to future generations via behavioural mechanisms. In California mice, testosterone maintains paternal HG behaviour. In the present study, we randomly assigned a group of male California mice to castration or sham-operated conditions and allowed them to raise their offspring normally. Adult sons of these males were paired with a female, and they were observed interacting with their own offspring. We found that like their fathers, the sons of castrated males huddled and groomed their young at lower levels than the sons of sham-operated fathers. The sons of castrates also retrieved pups more frequently. When both parents were present, the sons of castrates also showed a trend towards engaging in less exploratory behaviour. These data support the hypothesis that paternal behaviour, like maternal behaviour, can be transferred to future generations via epigenetic mechanisms and suggest that in a biparental species both parents contribute to offspring behavioural development.

Helium mobility in SON68 borosilicate nuclear glass: A nuclear reaction analysis approach  

NASA Astrophysics Data System (ADS)

The 3He behavior in the non active R7T7 type borosilicate glass called SON68 has been investigated using the implantation method to introduce helium in the material. Nuclear Reaction Analysis (NRA) was performed to follow the helium concentration depth profile evolution as a function of annealing time and temperature. In addition, in situ Transmission Electron Microscopy (TEM) has been implemented to study the formation of helium bubbles during both implantation and annealing processes. Numerical modeling with two different approaches is proposed and discussed to investigate the helium mobility mechanisms. Our study reveals for helium incorporation by implantation at low temperature the presence of several helium populations with disparate diffusivities. The most mobile helium fraction would be attributed to atomic diffusion. The corresponding activation energy value (0.61 eV) extracted from Arrhenius graphs is in good agreement with literature data. The results also highlight that the damages associated to helium sursaturation are the source of small helium clusters formation, with a reduced mobility instead of the atomic mobility measured by the infusion technique. Small cavities that support this assumption have been observed by TEM at low temperature.

Familial cardiofaciocutaneous syndrome in a father and a son with a novel MEK2 mutation.  

PubMed

Cardiofaciocutaneous (CFC) syndrome is a rare genetic disorder belonging to the group of RASopathies. It is typically characterized by congenital heart defects, short stature, dysmorphic craniofacial features, intellectual disability, failure to thrive, and ectodermal abnormalities such as hyperkeratosis and sparse, brittle, curly hair. CFC syndrome is caused by dominant mutations in one of the four genes BRAF, MEK1, MEK2, and KRAS. Only three familial cases of CFC syndrome have been reported to date, whereas the vast majorities are sporadic cases due to de novo mutations. We report on a fourth familial case with transmission of CFC syndrome from father to son due to a novel heterozygous sequence change c.376A>G (p.N126D) in exon 3 of MEK2 gene. This observation further documents the possibility of vertical transmission of CFC syndrome, which appears to be associated with rare mutations and relatively mild intellectual disability in affected individual. The hypomorphic effect of specific mutations particularly regarding neurocognitive issues may be related to the variable fertility of affected individuals. 2014 Wiley Periodicals, Inc. PMID:25487361

The Gelfand-Zeitlin integrable system and its action on generic elements of gl(n) and so(n)  

E-print Network

In recent work Bertram Kostant and Nolan Wallach ([KW1], [KW2]) have defined an interesting action of a simply connected Lie group $A$ isomorphic to \\mathbb{C}^{{n\\choose 2}} on gl(n) using a completely integrable system derived from Gelfand-Zeitlin theory. In this paper we show that an analogous action of \\mathbb{C}^{d} exists on the complex orthogonal Lie algebra so(n), where d is half the dimension of a regular adjoint orbit in so(n). In [KW1], Kostant and Wallach describe the orbits of $A$ on a certain Zariski open subset of regular semisimple elements in gl(n). We extend these results to the case of so(n). We also make brief mention of the author's results in [Col1], which describe all $A$-orbits of dimension {n\\choose 2} in gl(n).

Symmetry-protected topological order and negative-sign problem for SO(N) bilinear-biquadratic chains  

NASA Astrophysics Data System (ADS)

Using a generalized Jordan-Wigner transformation combined with the defining representation of the SO(N) spin, we map the SO(N) bilinear-biquadratic (BLBQ) spin chain into the N-color bosonic particle model. We find that, when the Jordan-Wigner transformation disentangles the symmetry-protected topological entanglement, this bosonic model becomes negative-sign-free in the context of quantum Monte Carlo simulation. For the SO(3) case, moreover, the Kennedy-Tasaki transformation for the S =1 BLBQ chain, which is also a topological disentangler, derives the same bosonic model through the dimer-R bases. We present the temperature dependence of the energy, entropy, and string order parameter for the SO(N =3,4,5) BLBQ chains by a world-line Monte Carlo simulation for the N-color bosonic particle model.

Son-Killer: A Third Extrachromosomal Factor Affecting the Sex Ratio in the Parasitoid Wasp, NASONIA (=MORMONIELLA) VITRIPENNIS  

PubMed Central

An extrachromosomal factor, termed son-killer (sk), affects the sex ratio in a parasitoid wasp, Nasonia (=Mormoniella ) vitripennis. The factor is maternally transmitted and alters the secondary sex ratio of an infected female through mortality of approximately 80% of the male embryos. No effect on the primary (zygotic) sex ratio is observed. Ninety-five percent of the daughters of an infected female inherit son-killer. The factor can also be transmitted contagiously when the progeny of infected and uninfected females develop simultaneously on a single host. In newly infected strains, the sex ratio effects are equivalent to those in the original. PMID:3988039

Does the differential cost of sons and daughters lead to sex ratio adjustment in great frigatebirds Fregataminor?  

Microsoft Academic Search

Sex allocation theory predicts that if benefits of producing sons and daughters differ and outweigh the costs of sex ratio adjustment, parents should produce more of the offspring that provide them with greater fitness. Potential benefits may be more likely to outweigh costs where sexual size dimorphism and, in birds, single-egg clutches exist. Great frigatebirds Fregata minor are seabirds in

An evolutionary psychological investigation of parental distress and reproductive coercion during the "coming out" of gay sons.  

PubMed

The lack of success of the "coming out" studies over the last three decades to explain and predict parental responses has motivated an evolutionary psychological reconceptualization. According to this reconceptualization, it was predicted that (a) biological mothers would experience more distress and apply more pressure on gay sons to change than would biological fathers and; (b) obligate investment for fathers on dependent sons would cause fathers to experience more distress and apply more pressure on gay sons to change than it would fathers without this obligate investment. In contrast, a cultural-norm hypothesis predicted that fathers would experience more distress and apply more pressure on gay sons to change than mothers. The majority of predictions were tested using 787 participants from two-biological parent families, who were drawn from a total sample of 891 participants from various family backgrounds. As predicted by the evolutionary hypothesis, biological mothers were reported to have been more distressed and coercive than biological fathers, in spite of a strong, societal expectation to the contrary. Furthermore, the results supported the obligate investment argument for paternal reactions. The model not only correctly explained and predicted parental behavior during coming out, but also was shown to unify within its theoretical framework discrepant results from the literature previously considered inconsistent.

Literature as an exploration of the phenomenology of schizophrenia: disorder and recovery in Denis Johnson's Jesus' Son.  

PubMed

When read as a fictional psychosis narrative, Jesus' Son, a collection of short stories by Denis Johnson, reveals important elements of the phenomenology of schizophrenia and recovery. It is possible that Jesus' Son, as a work of fiction, may be able to uniquely add depth and nuance to an understanding of the phenomenology of schizophrenia involving a state of psychological fragmentation, an ever-changing interpersonal field and a loss of personal agency. In addition, by following the protagonist in Jesus' Son as he begins to resolve some of his difficulties, the book also offers an individualised account of recovery. The authors detail how the book reveals these insights about schizophrenia and recovery and suggest that these elements are intertwined in such a manner that leads to a profound disruption of self-experience, characterised by a collapse of metacognitive processes. Jesus' Son may add depth to our understanding of the subjective experience of schizophrenia and recovery, and also may serve as one example in which the study of humanities offers an opportunity to explore the human elements in the most profound forms of suffering.

BiSON data preparation: a correction for differential extinction and the weighted averaging of contemporaneous data  

NASA Astrophysics Data System (ADS)

The Birmingham Solar Oscillations Network (BiSON) has provided high-quality high-cadence observations from as far back in time as 1978. These data must be calibrated from the raw observations into radial velocity and the quality of the calibration has a large impact on the signal-to-noise ratio of the final time series. The aim of this work is to maximize the potential science that can be performed with the BiSON data set by optimizing the calibration procedure. To achieve better levels of signal-to-noise ratio, we perform two key steps in the calibration process: we attempt a correction for terrestrial atmospheric differential extinction; and the resulting improvement in the calibration allows us to perform weighted averaging of contemporaneous data from different BiSON stations. The improvements listed produce significant improvement in the signal-to-noise ratio of the BiSON frequency-power spectrum across all frequency ranges. The reduction of noise in the power spectrum will allow future work to provide greater constraint on changes in the oscillation spectrum with solar activity. In addition, the analysis of the low-frequency region suggests that we have achieved a noise level that may allow us to improve estimates of the upper limit of g-mode amplitudes.

Electrical imaging of Narmada Son Lineament Zone, Central India from magnetotellurics  

NASA Astrophysics Data System (ADS)

The Narmada-Son Lineament (NSL) Zone is the second most important tectonic feature after Himalayas, in the Indian geology. Magnetotelluric (MT) studies were carried out in the NSL zone along a 130 km long NNE-SSW trending profile. The area of investigation extends from Edlabad (2046'16?; 7559'05?) in the South to Khandwa (2153'51?; 7618'05?) in the North. The data shows in general the validity of a two-dimensional (2D) approach. Besides providing details on the shallow crustal section, the 2D modeling results resolved four high conductive zones extending from the middle to deep crust, spatially coinciding with the major structural features in the area namely the Gavligarh, Tapti, Barwani-Sukta and Narmada South faults. The model for the shallow section has brought out a moderately resistive layer (30-150 ? m) representing the exposed Deccan trap layer, overlying a conductive layer (10-30 ? m) inferred to be the subtrappean Gondwana sediments, the latter resting on a high resistive basement/upper crust. The Deccan trap thickness varies from around a few hundred meters to as much as 1.5 km along the traverse. A subtrappean sedimentary basin like feature is delineated in the northern half of the traverse where a sudden thickening of subtrappean sediments amounting to as much as 2 km is noticed. The high resistive upper crust is relatively thick towards the southern end and tends to become thinner towards the middle and northern part of the traverse. The lower crustal segment is conductive over a major part of the profile. Considering the generally enhanced heat flow values in the NSL region, coupled with characteristic gravity highs and enhanced seismic velocities coinciding with the mid to lower crustal conductors delineated from MT, presence of zones of high density mafic bodies/intrusives with fluids, presumably associated with magmatic underplating of the crust in the zone of major tectonic faults in NSL region are inferred.

Kauffman knot invariant from SO(N) or Sp(N) Chern-Simons theory and the Potts model  

SciTech Connect

The expectation value of Wilson loop operators in three-dimensional SO(N) Chern-Simons gauge theory gives a known knot invariant: the Kauffman polynomial. Here this result is derived, at the first order, via a simple variational method. With the same procedure the skein relation for Sp(N) are also obtained. Jones polynomial arises as special cases: Sp(2), SO(-2), and SL(2,R). These results are confirmed and extended up to the second order, by means of perturbation theory, which moreover let us establish a duality relation between SO({+-}N) and Sp({+-}N) invariants. A correspondence between the first orders in perturbation theory of SO(-2), Sp(2) or SU(2) Chern-Simons quantum holonomy's traces and the partition function of the Q=4 Potts model is built.

Mothers Academic Gender Stereotypes and Education-Related Beliefs About Sons and Daughters in African American Families  

PubMed Central

The role of African American mothers academic gender stereotype endorsement in shaping achievement-related expectations for and perceptions of their own children was examined. Mothers (N = 334) of 7th and 8th graders completed measures of expectations for their children抯 future educational attainment, perceptions of their children抯 academic competence, and academic gender stereotypes. Consistent with hypotheses, mothers held less favorable expectations for sons and perceived sons to be less academically competent than daughters. In addition, mothers reported stereotypes favoring girls over boys in academic domains; stereotype endorsement, in turn, was related to mothers educational expectations for and beliefs about the academic competence of their own children, even with youths actual achievement controlled. Negative stereotypes about the academic abilities of African American boys may create a negative feedback loop, thereby contributing to the maintenance of the gender gap in African Americans educational outcomes.

QCD Precision Measurements and Structure Function Extraction at a High Statistics, High Energy Neutrino Scattering Experiment: NuSOnG  

SciTech Connect

We extend the physics case for a new high-energy, ultra-high statistics neutrino scattering experiment, NuSOnG (Neutrino Scattering On Glass) to address a variety of issues including precision QCD measurements, extraction of structure functions, and the derived Parton Distribution Functions (PDFs). This experiment uses a Tevatron-based neutrino beam to obtain a sample of Deep Inelastic Scattering (DIS) events which is over two orders of magnitude larger than past samples. We outline an innovative method for fitting the structure functions using a parameterized energy shift which yields reduced systematic uncertainties. High statistics measurements, in combination with improved systematics, will enable NuSOnG to perform discerning tests of fundamental Standard Model parameters as we search for deviations which may hint of 'Beyond the Standard Model' physics.

An X-linked sex ratio distorter in Drosophila simulans that kills or incapacitates both noncarrier sperm and sons.  

PubMed

Genomic conflict occurs when a genomic component gains a reproductive advantage at the expense of the organism as a whole. X-linked segregation distorters kill or incapacitate Y-bearing sperm, thereby gaining a transmission advantage but also reducing male fertility and generating a female-biased sex ratio. When some damaged, Y-bearing sperm survive and fertilize eggs, then the segregation distortion phenotype could be expanded by harming or killing sons in the next generation. X-linked son-killers are predicted by theory to be favored by natural selection and evolve when brothers and sisters compete for shared limiting resources and/or when brothers reduce the inclusive fitness of their sisters via sib-mating-a phenomenon called SA-zygotic drive. Here I develop and use a process-of-elimination screen to show that an unclassified X-linked sex ratio distorter (skew) in Drosophila simulans kills or incapacitates noncarrier sperm and also kills a substantial proportion of sons, i.e., it has both a segregation distortion and a SA-zygotic drive phenotype. There are three unique X-linked segregation distorters known to occur in D. simulans named Winters, Durham, and Paris. Autosomal-dominant suppressors of Winters (Nmy) and Durham (Tmy) failed to suppress skew. A Y-linked suppressor of Paris, however, did suppress skew, and a recombination test failed to detect recombinants between these two sex ratio distorters, indicating that they are tightly linked and plausibly identical or allelic. Son-killing may be an important yet unrecognized component of other X-linked segregation distorters. PMID:25081980

Distinct synaptic mechanisms create parallel S-ON and S-OFF color opponent pathways in the primate retina  

PubMed Central

Anatomical and physiological approaches are beginning to reveal the synaptic origins of parallel ON- and OFF-pathway retinal circuits for the transmission of short (S-) wavelength sensitive cone signals in the primate retina. Anatomical data suggest that synaptic output from S-cones is largely segregated; central elements of synaptic triads arise almost exclusively from the 揵lue-cone bipolar cell, a presumed ON bipolar, whereas triad-associated contacts derive primarily from the 揻lat midget bipolar cell, a hyperpolarizing, OFF bipolar. Similarly, horizontal cell connectivity is also segregated, with only the H2 cell-type receiving numerous contacts from S-cones. Negative feedback from long (L-) and middle (M-) wavelength sensitive cones via the H2 horizontal cells elicits an antagonistic surround in S-cones demonstrating that S versus L + M or 揵lue-yellow opponency is first established in the S-cone. However, the S-cone output utilizes distinct synaptic mechanisms to create color opponency at the ganglion cell level. The blue-cone bipolar cell is presynaptic to the small bistratified, 揵lue-ON ganglion cell. S versus L + M cone opponency arises postsynaptically by converging S-ON and LM-OFF excitatory bipolar inputs to the ganglion cell抯 bistratified dendritic tree. The common L + M cone surrounds of the parallel S-ON and LM-OFF cone bipolar inputs appear to cancel resulting in 揵lue-yellow antagonism without center-surround spatial opponency. By contrast, in midget ganglion cells, opponency arises by the differential weighting of cone inputs to the receptive field center versus surround. In the macula, the 損rivate-line connection from a midget ganglion cell to a single cone predicts that S versus L + M opponency is transmitted from the S-cone to the S-OFF midget bipolar and ganglion cell. Beyond the macula, OFF-midget ganglion cell dendritic trees enlarge and collect additional input from multiple L and M cones. Thus S-OFF opponency via the midget pathway would be expected to become more complex in the near retinal periphery as L and/or M and S cone inputs sum to the receptive field center. An important goal for further investigation will be to explore the hypothesis that distinct bistratified S-ON versus midget S-OFF retinal circuits are the substrates for human psychophysical detection mechanisms attributed to S-ON versus S-OFF perceptual channels.

Anatomical and physiological approaches are beginning to reveal the synaptic origins of parallel ON- and OFF-pathway retinal circuits for the transmission of short (S-) wavelength sensitive cone signals in the primate retina. Anatomical data suggest that synaptic output from S-cones is largely segregated; central elements of synaptic triads arise almost exclusively from the "blue-cone" bipolar cell, a presumed ON bipolar, whereas triad-associated contacts derive primarily from the "flat" midget bipolar cell, a hyperpolarizing, OFF bipolar. Similarly, horizontal cell connectivity is also segregated, with only the H2 cell-type receiving numerous contacts from S-cones.

Targeting of MAPK-associated molecules identifies SON as a prime target to attenuate the proliferation and tumorigenicity of pancreatic cancer cells  

PubMed Central

Background Pancreatic cancer is characterized by constitutive activation of mitogen-activated protein kinase (MAPK). Activation of MAPK is associated with the upregulation of genes implicated in the proliferation and survival of pancreatic cancer cells. We hypothesized that knockdown of these MAPK-associated molecules could produce notable anticancer phenotypes. Methods A RNA interference-mediated knockdown screening of 78 MAPK-associated molecules previously identified was performed to find molecules specifically associated with proliferation of pancreatic cancer cells in vitro. Expression of an identified molecule in pancreatic cancer tissues was examined by immunohistochemistry. In vivo tumorigenicity of cancer cells with stable knockdown of the molecule was assayed by using xenograft models. Flow cytometry and live cell imaging were employed to assess an association of the molecule with cell cycle. Results The knockdown screening revealed that knockdown of SON, the gene encoding SON, which is a large serine/arginine-rich protein involved in RNA processing, substantially suppressed pancreatic cancer cell proliferation and survival in vitro and tumorigenicity in vivo. SON expression was higher in ductal adenocarcinomas than in cells of normal ducts and precursor lesions in pancreatic cancer tissues. Knockdown of SON induced G2/M arrest and apoptosis in cultured cancer cells. The suppressive effect of SON knockdown on proliferation was less pronounced in cultured normal duct epithelial cells. SON formed nuclear speckles in the interphase of the cell cycle and dispersed in the cytoplasm during mitosis. Live cell imaging showed that SON diffusely dispersed in the early mitotic phase, accumulated in some foci in the cytoplasm in the late mitotic phase, and gradually reassembled into speckles after mitosis. Conclusion These results indicate that SON plays a critical role in the proliferation, survival, and tumorigenicity of pancreatic cancer cells, suggesting that SON is a novel therapeutic molecular target for pancreatic cancer.

Probing the solar cycle: a comparative and complementary analysis of GONG BiSON and VIRGO/LOI eigenfrequency shifts  

NASA Astrophysics Data System (ADS)

We use high-quality helioseismic data collected by GONG (over 4 <= l <= 140), BiSON (0 <= l <= 2) and VIRGO/LOI (0 <= l <= 8) to study the phenomenological nature of the cycle-induced (centroid) eigenfrequency variations. We have analyzed the frequency dependence of the shifts by fitting a power-law of the form ??nl ~ (?nl)?/Enl to the data (where the Enl are the mode inertias, and ? is the power-law index to be extracted). Previous studies have suggested that a relation with ? = 0 provides an adequate description of the shifts up to ? ? 3500 ?Hz. However, here we show that while nevertheless describing the shifts well up to ~2500 ?Hz, the linear scaling breaks down conspicuously at higher frequencies. Above this threshold, the shifts follow a power-law dependence with ? ~ 2. We also ahow that GONG shifts, averaged over different ranges in l together with the BiSON and LOI data averaged over their full quoted ranges, all scale at fixed frequency with the normalized mode inertia ratio Qnl (Christensen-Dalsgaard & Berthomieu 1991). This is to be expected if the solar-cycle perturbation affecting the modes is confined in the surface layers; the excellent agreement also reflects favourably on the external consistency of the different observations.

When mothers make sons sexy: maternal effects contribute to the increased sexual attractiveness of extra-pair offspring  

PubMed Central

Quality differences between offspring sired by the social and by an extra-pair partner are usually assumed to have a genetic basis, reflecting genetic benefits of female extra-pair mate choice. In the zebra finch (Taeniopygia guttata), we identified a colour ornament that is under sexual selection and appears to have a heritable basis. Hence, by engaging in extra-pair copulations with highly ornamented males, females could, in theory, obtain genes for increased offspring attractiveness. Indeed, sons sired by extra-pair partners had larger ornaments, seemingly supporting the genetic benefit hypothesis. Yet, when comparing ornament size of the social and extra-pair partners, there was no difference. Hence, the observed differences most likely had an environmental basis, mediated, for example, via differential maternal investment of resources into the eggs fertilized by extra-pair and social partners. Such maternal effects may (at least partly) be mediated by egg size, which we found to be associated with mean ornament expression in sons. Our results are consistent with the idea that maternal effects can shape sexual selection by altering the genotype杙henotype relationship for ornamentation. They also caution against automatically attributing greater offspring attractiveness or viability to an extra-pair mate's superior genetic quality, as without controlling for differential maternal investment we may significantly overestimate the role of genetic benefits in the evolution of extra-pair mating behaviour.

SON 68 nuclear glass alteration kinetics between pH 7 and pH 11.5  

NASA Astrophysics Data System (ADS)

The effect of the pH was investigated on the mechanisms of SON 68 (R7T7-type) glass alteration under `saturation' conditions in order to delimit the pH range within which a stable, protective gel is formed. Static experiments were conducted at 90癈 with an S/ V ratio of 50 cm-1 at various imposed pH values: 7, 8, 9.5, 10, 10.5, 11 and 11.5. An additional experiment was conducted with no restriction on the pH. The kinetic study showed that a protective gel formed in all the test media, although its stability was pH-dependent: at pH 11 or higher, the precipitation of a potassium and sodium aluminosilicate led to the degradation of the gel and the lose of its protective properties. This phenomenon resulted in renewed glass alteration, leading to complete and rapid degradation of the glass into alteration products. The aluminosilicate precipitation was found to be limited by the solubility of aluminum. Below pH 10, this type of secondary phase is unlikely to precipitate and the gel should remain stable. This study, based on thermodynamic and kinetic considerations, suggests that aqueous alteration of the French SON 68 nuclear glass results in the formation of a protective gel with long-term stability between pH 7 and pH 10.

Prepubertal start of father's smoking and increased body fat in his sons: further characterisation of paternal transgenerational responses.  

PubMed

Despite interest in the idea that transgenerational effects of adverse exposures might contribute to population health trends, there are few human data. This non-genetic inheritance is all the more remarkable when transmission is down the male-line as reported in a historical Swedish study, where the paternal grandfather's food supply in mid childhood was associated with the mortality rate in his grandsons. Using the Avon Longitudinal Study of Parents and Children's questionnaire data on smoking and smoking onset from 9886 fathers, we examined the growth of their children from 7-17 years. Adjusting for potential confounders, we assessed associations between body mass index (BMI), waist circumference, total fat mass and lean mass with the age at which the father had started smoking regularly. Of 5376 fathers who reported having ever smoked, 166 reported regular smoking <11 years of age. Before adjustment, those offspring whose fathers started smoking <11 years had the highest mean BMIs at each age tested. The adjusted mean differences in BMI, waist circumference and total fat mass in those sons whose fathers started smoking <11 years, compared with all other sons, increased with age, being significantly greater from 13 years onwards. There were no significant BMI associations in daughters, but they showed a reduction in total lean mass. Our results highlight the importance of the developmental timing of the paternal exposure as well as gender differences in offspring outcomes. Smoking by boys in mid childhood may contribute to obesity in adolescent boys of the next generation. PMID:24690679

Analytical modeling of linearly graded alloy material gate recessed ultra thin body source/drain SON MOSFET  

NASA Astrophysics Data System (ADS)

An explicit analytical model of surface potential profile and threshold voltage of work function engineered gate (WFEG) recessed source/drain (Re S/D) MOSFET has been presented in this paper. A two dimensional Poisson's equation has been solved with parabolic potential approximation to establish the expressions of front and back channel surface potential distribution and the threshold voltage has been derived from the minima of such obtained potential. In this work, the benefits of linearly graded binary alloy gate and recessed source/drain structures are expected to be available simultaneously in ultra short channel SOI/SON MOSFETs structures. Analytical results are compared with those obtained from the 2D MEDICI device simulator to validate our present model.

Intergenerational support of Chinese rural elders with migrant children: do sons' or daughters' migrations make a difference?  

PubMed

This article investigates how the out-migration of adult children affects monetary, instrumental, and emotional support of Chinese rural elders over a 5-year interval, and whether the gender of migrant children makes a difference in such relationships. With a sample of 1,006 older parents (60+) in rural Anhui province, the result of hierarchical regression analyses showed that support from adult children was mainly needs based. Declining income of older parents related to increased monetary support. Experiencing widowhood and difficulties with instrumental activities of daily living was associated with higher probability of receiving instrumental support. Beyond expanding parental needs, only the out-migration of sons led to more monetary and emotional support among elders over time. Implications for policy, social work practice, and future research are discussed. PMID:19585327

Deletion of locus D15S113 in a mother and son without features of Angelman syndrome  

SciTech Connect

Deletions of the proximal long arm of chromosome 15 result in Angelman syndrome when inherited from the mother and Prader-Willi syndrome when inherited from the father. The minimal critical deletion region for Angelman syndrome has been reported to include D15S74 (B1.5), D15S10 (TD3-21), and D15S113 (LS6-1). We report a mother and son who have deletions that include D15S113 but who do not have features of Angelman syndrome. D.H. is a 10-year-old white male referred for genetic evaluation due to mental retardation. He has mild to moderate mental retardation and minor dysmorphic features, including downslanting palpebral fissures, prominent nose, broad forehead, small chin, midface hypoplasia, and large ears. His mother (B.S.) has slightly downslanting palpebral fissures and a borderline intellectual deficit. Neither individual has the seizures, excessive laughter, hand clapping, ataxia or facial dysmorphism which are characteristic of Angelman syndrome. The linear order of probes mapping to 15q11-q13 is 15cen-D15S11-D15S13-D15S10-D15S113-GABRB3-D15S12-tel. The proximal border of the deletion in our patients lies between D15S10 and D15S113. The fact that these two individuals do not have Angelman syndrome, despite deletion of D15S113, suggests that the Angelman syndrome critical deletion region should be further refined to exclude the D15S113 locus. In addition, the findings of a more severe intellectual impairment in the son than in the mother suggests that the region immediately telomeric to the critical deletion region for Angelman syndrome may contain imprintable genes that influence intellectual function.

Hydrological changes in western Central Asia (Kyrgyzstan) during the Holocene as inferred from a palaeolimnological study in lake Son Kul  

NASA Astrophysics Data System (ADS)

The hydrology of western Central Asia is highly sensitive to climatic perturbations. In order to understand its long-term variability and to infer linkages between precipitation and atmospheric and oceanic systems, we conducted a thorough sedimentary and geochemical study on a composite core retrieved in lake Son Kul (central Kyrgyzstan). A multi-proxy approach was conducted on lake sediments based on grain size analyses, magnetic susceptibility, total organic carbon (TOC), total nitrogen (TN) and carbon and oxygen isotope analyses on bulk and biogenic materials (ostracoda and molluscs shells) at a resolution equivalent to ca40 years, aiming to characterise the sequence of palaeolimnological changes in Son Kul. As indicated by ?18O record of bulk carbonates, mainly consisting of aragonite, the Holocene hydrological balance was negative during most of time, suggesting an excess of evaporation (E) over precipitation (P). Limnological conditions fluctuated rapidly before 5000燾al爕r燘P indicating significant changes in regional hydrology and climate. In particular, the long-term negative hydrological balance was impeded by several short stages with marked increase of precipitation, lasting several decades to a few centuries (e.g., 8300-8200, 6900-6700, 6300-6100, 5500-5400, 5300-5200 and 3100-3000燾al爕r燘P). Precipitation changes as inferred from ?18O data are also documented by increased minerogenic detritus and higher TOC. We propose that the seasonal pattern of precipitation varied transiently in western Central Asia during the Holocene, although evaporation changes may also account for the rapid changes observed in ?18O data. When the annual water balance was less critical (P?燛), the excess of water might be ascribed to increased precipitation during cold seasons mainly because winter precipitation has more negative ?18O than its summer equivalent. Conversely, when the annual water balance is negative (P?燛), the moisture was mainly delivered during the warm season, as between 5000 and 2000燾al爕r燘P. Our results thus imply that moisture sources could have changed as well during the Holocene. Moisture was delivered as today mainly during summer from the extended Caspian-Aral Basin and eastern Mediterranean, although Arctic and even North Atlantic seas might be important moisture sources when seasonal precipitation was dominated by winter precipitation. We hypothesise that warming Arctic and North Atlantic seas were important for the North Hemisphere circulation during the cold season.

Regional vegetation patterns at lake Son Kul reveal Holocene climatic variability in central Tien Shan (Kyrgyzstan, Central Asia)  

NASA Astrophysics Data System (ADS)

A multiproxy study was conducted on Holocene sediments from the alpine lake Son Kul (3010 m a.s.l, 4148?33N/7507?38E) in central Tien Shan (Kyrgyzstan). The combination of high-resolution pollen, palynofacies and magnetic susceptibility data allowed reconstruction of changes in sedimentary and vegetation dynamics regionally at Son Kul between 8350 and ca 2000 cal. BP. Using pollen data to quantify climatic parameters, a quantitative reconstruction of climatic conditions was performed using the "Modern Analogue Vegetation types" (MAV) method and a ranged index of seasonality. The most temperate (e.g. moister) climate conditions occurred between 8350 and 5000-4500 cal. BP when alpine meadow vegetation was enriched in plants requiring moister conditions and trees developed regionally. Conversely, more continental and arid conditions prevailed after 4500 cal. BP with the decline of arboreal vegetation (especially Juniperus) and the extension of an alpine steppe-meadow along with a regional decrease in Poaceae. This climate transition was associated with a change in seasonality as the continentality greatly intensified after 5000-4500 cal. BP. Our results are consistent with other records from the Tien Shan range and the Chinese Province Xinjiang showing that relatively wet conditions prevailed regionally before 5000 cal. BP, whereas reduced moisture conditions were established after that time. From a more global perspective, we highlight that regional rainfall in central Tien Shan and western Central Asia is likely to be predominantly controlled by the Eastern Mediterranean cyclonic system and North Atlantic climate, as based on the close correspondence between climatic archives from western Central Asia, the Levant, the Eastern Mediterranean and Caspian Sea regions. However, the effect of monsoonal dynamics on the regional climatic system in central Tien Shan still remains dubious, since recent modelling studies have shown that no dynamic link exists between humidity in Central Asia and the Indian Summer Monsoon. This study pinpoints the need to explore the effect of remote Eurasian atmospheric circulation patterns on past climate variability in Central Asia.

How parasitoid females produce sexy sons: a causal link between oviposition preference, dietary lipids and mate choice in Nasonia  

PubMed Central

Sexual selection theory predicts that phenotypic traits used to choose a mate should reflect honestly the quality of the sender and thus, are often costly. Physiological costs arise if a signal depends on limited nutritional resources. Hence, the nutritional condition of an organism should determine both its quality as a potential mate and its ability to advertise this quality to the choosing sex. In insects, the quality of the offspring's nutrition is often determined by the ovipositing female. A causal connection, however, between the oviposition decisions of the mother and the mating chances of her offspring has never been shown. Here, we demonstrate that females of the parasitic wasp Nasonia vitripennis prefer those hosts for oviposition that have been experimentally enriched in linoleic acid (LA). We show by 13C-labelling that LA from the host diet is a precursor of the male sex pheromone. Consequently, males from LA-rich hosts produce and release higher amounts of the pheromone and attract more virgin females than males from LA-poor hosts. Finally, males from LA-rich hosts possess three times as many spermatozoa as those from LA-poor hosts. Hence, females making the right oviposition decisions may increase both the fertility and the sexual attractiveness of their sons. PMID:21429922

Cognitive ability correlates positively with son birth and predicts cross-cultural variation of the offspring sex ratio  

NASA Astrophysics Data System (ADS)

Human populations show remarkable variation in the sex ratio at birth which is believed to be related to the parental condition. In the present study, the global variation of sex ratio at birth (SRB, proportion of male offspring born) was analyzed with respect to indirect measure of condition, the intelligence quotient (IQ). IQ correlates strongly with lifespan across nations, which makes it a good indicator of health of the large populations. Relation between three standard measures of average national IQ and SRB was studied using multiple linear regression models. Average national IQ was positively correlated with SRB ( r = 0.54 to 0.57, p < 0.001). Further, IQ emerged as a powerful predictor of SRB after controlling for the effects of all the known covariates like fertility, maternal age, polygyny prevalence, wealth, son preference, latitude, low birth weight, and neonatal mortality in the regression models. These results suggest that the striking variation of offspring sex ratio across nations could be caused in part by the difference in general condition of populations.

Experiments were conducted in flow-through conditions (solution flow rate 3-5 mL/day) at pH 8.0, 9.5, and 10.5 under various initial Si concentrations, a glass surface-to-volume ratio near 14,000 m -1 and at a temperature of 90 癈. This set of long-term experiments (200 days) showed leaching rates dependent on the initial silica concentration and the initial pH. Interpretation of results at pH 8.0 was difficult due to the use of a synthetic water used to represent waters found at a potential French repository site. Because very small glass powder sizes were used ( = 1 ?m), a complete dissolution of the pristine glass was achieved at low initial silica concentrations where higher leaching rates were produced. In all cases, initial high normalized leaching rates were observed followed by a decrease in leaching rate with rate levels ranging from 9 (4) to 5 (3) 10 -4 g m -2 d -1 at 200 days under silica saturated conditions at pH 9.5 and 10.5, respectively. We have compared these results to previous results obtained in similar leaching conditions. Modeling using the GM2004 model program and model output values were shown to be in agreement with experimental results.

Epidemiology of transthyretin-associated familial amyloid polyneuropathy in the Majorcan area: Son Ll鄑zer Hospital descriptive study  

PubMed Central

Background Transthyretin-associated Familial Amyloid Polyneuropathy (TTR-FAP) is an autosomal dominant disease caused by the deposition of abnormal transthyretin that results from a gene mutation. Although rare worldwide, there are descriptions of several endemic foci, such as in Majorca, Balearic Islands, Spain. We aimed at describing a contemporary series of TTR-FAP patients in Son Ll鄑zer Hospital in Majorca from an epidemiological point of view in order to report their main clinical and laboratory characteristics. Methods A retrospective, observational study was performed. Medical records from adult patients diagnosed with TTR-FAP from a single hospital were reviewed. Results Out of a total of 107 cases, 75 subjects were included: asymptomatic carriers (52.3%) and symptomatic patients (47.7%). Mean age was 58.3爕ears at the time of the study, and 50.7% were men. Mean age at diagnosis was 49.8爕ears. In addition, 42 patients (39.2%) had received a liver transplant, and time to liver transplantation was on average 29.56爉onths from the initial diagnosis. They all had the Val30Met mutation. The organs of the nervous system were those most frequently impaired (57.3%), and 83.9% of the symptomatic patients were fully ambulant (stage 1). Family history was reported in 69.3% of the cases, with the patient抯 father being the most commonly affected relative. Comorbidities were frequent, with high blood pressure being the most common. Conclusions Our findings provide additional information on this condition and are useful for describing the demographic features, clinical presentation, diagnosis, and natural course of TTR-FAP in Majorca.

Role of the histone domain in the autoinhibition and activation of the Ras activator Son of Sevenless  

PubMed Central

Membrane-bound Ras is activated by translocation of the Son of Sevenless (SOS) protein to the plasma membrane. SOS is inactive unless Ras is bound to an allosteric site on SOS, and the Dbl homology (DH) and Pleckstrin homology (PH) domains of SOS (the DH-PH unit) block allosteric Ras binding. We showed previously that the activity of SOS at the membrane increases with the density of PIP2 and the local concentration of Ras-GTP, which synergize to release the DH-PH unit. Here we present a new crystal structure of SOS that contains the N-terminal histone domain in addition to the DH-PH unit and the catalytic unit (SOSHDFC, residues 11049). The structure reveals that the histone domain plays a dual role in occluding the allosteric site and in stabilizing the autoinhibitory conformation of the DH-PH unit. Additional insight is provided by kinetic analysis of the activation of membrane-bound Ras by mutant forms of SOS that contain mutations in the histone and the PH domains (E108K, C441Y, and E433K) that are associated with Noonan syndrome, a disease caused by hyperactive Ras signaling. Our results indicate that the histone domain and the DH-PH unit are conformationally coupled, and that the simultaneous engagement of the membrane by a PH domain PIP2-binding interaction and electrostatic interactions between a conserved positively charged patch on the histone domain and the negatively charged membrane coincides with a productive reorientation of SOS at the membrane and increased accessibility of both Ras binding sites on SOS.

Arabidopsis SON1 Is an F-Box Protein That Regulates a Novel Induced Defense Response Independent of Both Salicylic Acid and Systemic Acquired Resistance  

PubMed Central

One of several induced defense responses in plants is systemic acquired resistance (SAR), which is regulated by salicylic acid and in Arabidopsis by the NIM1/NPR1 protein. To identify additional components of the SAR pathway or other genes that regulate SAR-independent resistance, we performed genetic suppressor screens of mutagenized nim1-1 seedlings, which are highly susceptible to infection by Peronospora parasitica. We isolated the son1 (suppressor of nim1-1) mutant, which shows full restoration of pathogen resistance without the induction of SAR-associated genes and expresses resistance when combined with a salicylate hydroxylase (nahG) transgene. These features indicate that son1-mediated resistance is distinct from SAR. Resistance is effective against both the virulent oomycete Peronospora and the bacterial pathogen Pseudomonas syringae pv tomato strain DC3000. We cloned SON1 and found it to encode a novel protein containing an F-box motif, an element found within the specificity determinant in the E3 ubiquitin-ligase complex. We propose the existence of a novel defense response that is independent of SAR and negatively regulated in Arabidopsis by SON1 through the ubiquitin-proteosome pathway. PMID:12119368

Stratigraphic Units in Las Vegas Valley, Nevada  

NASA Astrophysics Data System (ADS)

Using 25 well logs, 15 of which also had accompanying geophysical and aquifer test data were used to describe and establish three alloformations including the Tule Spring and Paradise Valley Alloformations and four aquiformations, the most well defined being, the Las Vegas Springs Aquiformation, in the west central part of the bolson (Donovan, 1996), primarily in Township 20 South, Range 60 East, Mount Diablo Baseline and Meridian (MDBLM), with the stratotypes designated in T20S, R61E S31 MDBLM (36 9'59.89"N 11511'26.34"W). The allostratigraphic units were developed using the recommendations in the North American Code of Stratigraphic Nomenclature (NACSN, 1983 and 2005). The hydrostratigraphic units were developed following the recommendations of Seaber (1992). The units constitute the bulk of the upper 500 meter section. Twenty additional wells in the same geographic area, drilled and completed between 1995 and 2005 with detailed geologic and hydrologic information provided confirmation of these units. The proposed stratigraphic units are not part of either, and are located between, the two previously named and non-contiguous formations in the bolson (the Miocene Muddy Creek Formation and the late Pleistocene Las Vegas Formation) (Longwell et al 1965). Las Vegas Valley contains a metropolitan area of approximately two million people. The deeper part of the alluvial basin below 300 ft below ground surface is of interest for supply and storage. The shallower part is of interest for water quality and the interaction between the ground water system and engineered structures.

A 25-year laboratory experiment on French SON68 nuclear glass leached in a granitic environment - First investigations  

NASA Astrophysics Data System (ADS)

We have investigated a 25.75-year old leaching experiment to improve our understanding of the mechanisms controlling glass dissolution in geological disposal conditions. A SON68 glass block was leached in slowly renewed synthetic groundwater (at 90 癈, 100 bar) in contact with some pieces of granite and Ni-Cr-Mo alloy as environmental storage materials. One hundred and sixty-three samplings were carried out over the entire duration of the experiment and were used to calculate the mean thickness of the altered glass (28 (9) ?m) and the glass dissolution rate. After few months, the rate remained very constant at 6 10 -3 g m -2 d -1 which is about 20 times higher than the residual rate measured in a batch reactor at the same temperature. At the end of the experiment, mainly SEM analyses were performed on the entire glass block. Surprisingly, the glass alteration layer has neither a homogeneous thickness, nor a homogeneous morphology. The location of the sampling valve (at half height of the glass block) seems to divide the glass block into two parts. In the upper half (above the sampling valve), the general morphology of the alteration layer consists in a relatively simple and uniform gel and some secondary phases which are rare-earth phosphates. The mean measured thickness of this alteration layer is 6.7 (0.3) ?m. However, in the lower half of the glass block, the gel is globally larger and frequently contains rounded shapes which are rare-earth phosphates. This section is edged by secondary phases bearing Mg, Na, Zn and Ni. The mean measured thickness is 81.3 (1.1) ?m in the lower half. In this experiment, the flow rate which leads to the hydrodynamic transport of the soluble species must be a key factor for the local glass alteration process. We have also shown that this unexpected behavior is likely due to heterogeneities of the chemistry of the solution. This conclusion is supported by the behavior of Mg. This element, supplied by the inlet solution, precipitates with Si and forms clay minerals and therefore weakens the passivating properties of the gel. Mg-rich clay minerals are only observed in the lower half of the glass block. Further investigations are necessary to better understand the coupling between the hydrodynamics and chemistry in this experiment. However, based on this study, we can conclude that glass in disposal should be very sensitive to the water renewal near the glass surface.

Parents' experience of living with and caring for an adult son or daughter with schizophrenia at home in Ireland: a qualitative study.  

PubMed

This study explored the experience of parents living with, and caring for, an adult son or daughter with schizophrenia. There is increasing emphasis on the involvement of carers and users in the care for people with schizophrenia. 'A Vision for Change' highlights the need for a partnership approach and emphasizes that carers are an integral part in the planning and delivery of mental health services. In order to meet such requests, it was necessary to explore the meaning of caregiving for Irish families. A descriptive qualitative design was used to enable parents to describe their experiences. Semi-structured, in-depth interviews with a convenience sample of six parents in Ireland were carried out in 2007. The study encompassed four major themes: psychological tsunami, caring activities, coping with enduring illness and an uncertain pathway. Parents reported severe psychological distress when their son or daughter was diagnosed with schizophrenia. Their deep sense of loss was followed by acceptance of the situation. Feelings of love and a sense of responsibility helped to give meaning to their caring role. This study gave a voice to some parents of a son or daughter with schizophrenia. A family-centred approach should be at the core of care planning for this vulnerable population. PMID:23593964

A father and son with mental retardation, a characteristic face, inv(12), and insertion trisomy 12p12.3-p11.2.  

PubMed

A male patient with mental retardation (MR) and mild facial features was shown by high-resolution G-banding to have pericentric inversion of chromosome 12 with an unknown segment inserted into the long arm of the inverted chromosome [46,XY,inv(12)(pter-->p11.2::q14.1-->p11.2::?::q14.1-->qter)]. Both the inverted chromosome 12 and clinical manifestations were transmitted to his son. Karyotypes of the propositus' parents were normal. Studies with fluorescence in situ hybridization (FISH) in both the propositus and his son revealed that the extra segment was derived from 12p. Further FISH mapping and the genome-wide copy number detection by GeneChip Mapping 100K Array showed that an 11-Mb segment of 12p between two BAC clones, RP11-22H10 and RP11-977P2, was inserted at one of the reunion points in the long arm of the inv(12) chromosome. Analysis of parent-child transmissions of duplicated alleles using microsatellite markers defined the maternal origin of the chromosomal anomaly in the propositus and suggested a mechanism of its formation through a sister-chromatid rearrangement (SCR), that is, mismatched pairing and unequal crossover between sister chromatids as well as three break rearrangements including a U type rearrangement. Karyotypes of the propositus and his son were thus inv(12)(pter-->p11.22::q14.1-->p12.3::q14.1-->qter). This is the first report of "pure" proximal 12p-trisomy including p12.3-p11.22 region.

Familial Ainhum: A Case Report of Multiple Toe Involvement in a Father and Son, Staging of Ainhum with Insight into Different Types of Constricting Bands  

PubMed Central

Ainhum, also known as dactylolysis spontanea, is a painful constriction of the base of the fifth toe, frequently followed by spontaneous amputation a few years later. The disease is often symmetrical on both the feet, but, occasionally, other toes are also affected and rarely the distal phalanx of the fifth finger. Pseudoainhum is a similar condition that occurs as a secondary event resulting from certain hereditary and nonhereditary diseases that lead to annular constriction of digits. We hereby present a case of familial ainhum in father and son with multiple toes affected, autoamputation, and more involvement of fourth toe than the fifth toe, which is a very rare finding.

Cell-type specific expression of the vasopressin gene analyzed by AAV mediated gene delivery of promoter deletion constructs into the rat SON in vivo.  

PubMed

The magnocellular neurons (MCNs) in the supraoptic nucleus (SON) of the hypothalamus selectively express either oxytocin (Oxt) or vasopressin (Avp) neuropeptide genes. In this paper we examine the cis-regulatory domains in the Avp gene promoter that are responsible for its cell-type specific expression. AAV vectors that contain various Avp gene promoter deletion constructs using EGFP as the reporter were stereotaxically injected into the rat SON. Two weeks following the injection immunohistochemical assays of EGFP expression from these constructs were done to determine whether the expressed EGFP reporter co-localizes with either the Oxt- or Avp-immunoreactivity in the MCNs. The results identify three major enhancer domains located at -2.0 to -1.5 kbp, -1.5 to -950 bp, and -950 to -543 bp in the Avp gene promoter that regulate the expression in Avp MCNs. The results also show that cell-type specific expression in Avp MCNs is maintained in constructs containing at least 288 bp of the promoter region upstream of the transcription start site, but this specificity is lost at 116 bp and below. Based on these data, we hypothesize that the -288 bp to -116 bp domain contains an Avp MCN specific activator and a possible repressor that inhibits expression in Oxt-MCNs, thereby leading to the cell-type specific expression of the Avp gene only in the Avp-MCNs.

A new efficient method for determining weighted power spectra: detection of low-frequency solar p-modes by analysis of BiSON data  

E-print Network

We present a new and highly efficient algorithm for computing a power spectrum made from evenly spaced data which combines the noise-reducing advantages of the weighted fit with the computational advantages of the Fast Fourier Transform (FFT). We apply this method to a 10-year data set of the solar p-mode oscillations obtained by the Birmingham Solar Oscillations Network (BiSON) and thereby uncover three new low-frequency modes. These are the l=2, n=5 and n=7 modes and the l=3, n=7 mode. In the case of the l=2, n=5 modes, this is believed to be the first such identification of this mode in the literature. The statistical weights needed for the method are derived from a combination of the real data and a sophisticated simulation of the instrument performance. Variations in the weights are due mainly to the differences in the noise characteristics of the various BiSON instruments, the change in those characteristics over time and the changing line-of-sight velocity between the stations and the Sun. It should be...

Deletion involving D15S113 in a mother and son without Angelman syndrome: Refinement of the Angelman syndrome critical deletion region  

SciTech Connect

Deletions of 15q11-q13 typically result in Angelman syndrome when inherited from the mother and Prader-Willi syndrome when inherited from the father. The critical deletion region for Angelman syndrome has recently been restricted by a report of an Angelman syndrome patient with a deletion spanning less than 200 kb around the D15S113 locus. We report here on a mother and son with a deletion of chromosome 15 that includes the D15S113 locus. The son has mild to moderate mental retardation and minor anomalies, while the mother has a borderline intellectual deficit and slightly downslanting palpebral fissures. Neither patient has the seizures, excessive laughter and hand clapping, ataxia or the facial anomalies which are characteristic of Angelman syndrome. The proximal boundary of the deletion in our patients lies between the D15S10 and The D15S113 loci. Our patients do not have Angelman syndrome, despite the deletion of the D15S113 marker. This suggests that the Angelman syndrome critical deletion region is now defined as the overlap between the deletion found in the previously reported Angelman syndrome patient and the region that is intact in our patients. 28 refs., 6 figs.

Estudio comparativo de las mol閏ulas isovalentes de inter閟 atmosf閞ico CF3Cl y CF3Br y sus correspondientes hal骻enos aislados Cl y Br.  

NASA Astrophysics Data System (ADS)

Los estados Rydberg moleculares han suscitado en los 鷏timos a駉s un creciente inter閟 entre los espectroscopistas experimentales, motivado en parte por el desarrollo de nuevas t閏nicas espectrosc髉icas capaces de investigar estos estados altamente excitados electr髇icamente. Los procesos de fotoabsorci髇 que implican estados Rydberg en los derivados halogenados del metano son de gran importancia, debido a su abundancia en la atm髎fera y a sus implicaciones medioambientales. Por ello, la obtenci髇 de datos relativos a sus fuerzas de oscilador es de gran inter閟. En este trabajo se aborda el estudio de dichas propiedades para las mol閏ulas isovalentes CF3Cl y CF3Br. Ambas mol閏ulas presentan id閚tica estructura electr髇ica para el estado fundamental por lo que se espera que sus espectros Rydberg presenten grandes similitudes, en ausencia de perturbaciones. Por ello y dada la escasez de datos relativos a fuerzas de oscilador, hemos establecido la correcci髇 de nuestros resultados en base a las analog韆s esperadas en las intensidades espectrales correspondientes a transiciones an醠ogas. Por otro lado, Novak y col. [1] han encontrado experimentalmente un marcado car醕ter at髆ico en el espectro correspondiente a estas mol閏ulas, siendo muy similar a los de los 醫omos de Cl y Br. Por ello en el presente trabajo, adem醩 de establecer la comparaci髇 entre ambas mol閏ulas hemos buscado las similitudes con sus respectivos hal骻enos. Los c醠culos relativos a las especies moleculares se han realizado utilizando la Metodolog韆 Mol閏ular de Orb韙ales de Defecto Cu醤tico (MQDO) [2], mientras que para el estudio de los 醫omos de Cl y Br se emple la versi髇 relativista del m閠odo (RQDO) [3].

Safety of the Las Vegas left-turn display.  

PubMed

This paper provides a safety evaluation of a special protected/permitted left turn signal control (Las Vegas LT Display) that has been implemented in the urbanized area of Las Vegas, Nevada. The Las Vegas LT Display eliminates the yellow trap condition for leading approach in lead/lag operation. It provides protected only left turns during certain times of day by suppressing the permitted green ball and yellow ball displays. Before and after studies were conducted using the crash data from 10 intersections. Results from the analyses indicated that no obvious safety concerns due to use of the special display.

The phenomenology of solar-cycle-induced acoustic eigenfrequency variations: a comparative and complementary analysis of GONG, BiSON and VIRGO/LOI data  

NASA Astrophysics Data System (ADS)

We use high-quality helioseismic data collected by three different observational programmes during the declining phase of activity cycle 22,Q7 and a substantial portion of the rising phase of the current cycle (23), to study the phenomenological nature of the cycle-induced (centroid) eigenfrequency variations. We have analysed the frequency dependence of the shifts by fitting a power law of the form ??nl~(?nl)?/Enl to the data (where the Enl are the mode inertias, and ? is the power-law index to be extracted). Previous studies have suggested that a relation with ?=0 provides an adequate description of the shifts up to ?~3500?Hz. However, here we show that while nevertheless describing the shifts well up to ~2500?Hz, the linear scaling breaks down conspicuously at higher frequencies. Above this threshold, the shifts follow a power-law dependence with ?~2. Our analyses (for 1600<=?<=4000?Hz) make use of observations made by the ground-based GONG over the angular degree range 4<=l<=150 the ground-based BiSON over 0<=l<=2 and the VIRGO/LOI instrument on board the ESA/NASA SOHO satellite over 0<=l<=8. We show that GONG shifts averaged over different ranges in l, together with the BiSON and LOI data averaged over their full quoted ranges, all scale at fixed frequency with the normalized mode inertia ratio QnlQ1. This is to be expected if the solar-cycle perturbation affecting the modes is confined in the surface layers; the excellent agreement also reflects favourably on the external consistency of the different observations.

Shallow Crustal Configuration of the Narmada-Son Lineament Transition Zone Near the Sahdol-Katni Area of Central India Using Simultaneous Gravity and Magnetic Observations  

NASA Astrophysics Data System (ADS)

Gravity and magnetic studies have been carried out to map the different depth formations of alluvium, Gondwana, Vindhyan, Mahakoshal, and the crystalline basement in the Narmada-Son lineament (NSL) near the Sahdol-Katni area, India. Higher elevations in the northern part of the study area have lower gravity; the southern part of the study area, however, is moderately elevated and also has a higher gravity anomaly, which justifies the isostatic adjustment. This indicates the presence of high-density material, for example Mahakoshal rocks, in the upper crust which causes the higher anomaly value. The Mahakoshal rocks are widely exposed at Mau, Chanaura, Nadawar, Khamaria, Umria, and near the Tala-Barhi area and also extend from Sidhi to Agoni village further east of the area. The Mahakoshal rocks are thinner between the river Son and Tikwa village which causes a different gravity anomaly pattern changing from the NNE-SSW direction to the N-S direction. However, the trend of magnetic anomaly follows the same pattern toward the NNE-SSW direction, mainly because of the effect of the crystalline basement. Two magnetic highs are prominent in the Tikwa and Amarpur regions, 800 and 400 nTesla, respectively, because of the presence of the crystalline basement. The depth of the crystalline basement obtained by 2 D gravity-magnetic modelling varies from 2.7 to 2.9 km. From spectral analysis the average depth of the crystalline basement varies from 2.83 to 3.05 km. The different crustal depth sections obtained by 2 D simultaneous gravity-magnetic modelling correlate well with other constrained data.

Wintertime aerosol in Las Vegas, Nevada  

NASA Astrophysics Data System (ADS)

Numerous studies have found adverse health effects in subjects who live next to major roadways due to air pollution; in particular, there can be severe impacts on lung function and development in children living and/or attending school next to major roadways due to their exposure to air pollutants, including particulate matter (PM) or aerosol. The composition of aerosol at an elementary school next to a major freeway in Las Vegas, Nevada during winter 2008 was measured using a suite of measurements. An Aerodyne High Resolution Aerosol Mass Spectrometer (HR-AMS) was used to quantify the composition of non-refractory PM1 aerosol, including organic matter (OM); an Aethalometer was used to quantify black carbon (BC); a Sunset OCEC analyzer was used to measure organic and elemental carbon (OC, EC); and a particle-into-liquid system (PILS) coupled to two ion chromatographs (IC) was used to measure fine particle ions. Hi-volume PM2.5 samplers were used to collect aerosol on quartz fiber filters at between 2 and 24 hour intervals during the study, a subset of which were analyzed for PAHs and the biomass burning tracer levoglucosan. Data were analyzed by positive matrix factorization (PMF) to determine the amount of fresh, hydrocarbon-like organic aerosol (HOA), more oxidized OA (low-volatility and semi-volatile OA [LV-OOA, SV-OOA]) and biomass burning OA (BBOA). PM1 aerosol was predominantly carbonaceous, with OM plus BC accounting for 74% of the overall average 6.9 mug/m3 of PM measured. BC had a diurnal pattern similar to traffic volume, while OM was higher in the evening compared to the morning. OM was a mixture of fresh HOA, urban- and regional-scale OOA, and BBOA; in the evening, SV-OOA and BBOA peaked, while HOA concentrations were on average the same in the morning and evening, similar to BC. OM/OC ratios were low (1.52 +/-0.14 on average) during the morning rush hour (average OM = 2.4 mug/m3) when vehicular emissions dominate this near-road measurement site, and even lower (1.46 +/- 0.10) in the evening (average OM=6.3 mug/m3), when a combination of vehicular and fresh residential biomass burning emissions was typically present during a period characterized by strong atmospheric stability. While nitrate and sulfate had size distributions typical of secondary species with a sharp peak in particle diameter between 400 nm and 500 nm, OM had a broader distribution between 100 nm and 400 nm diameter particles, reflecting its combination of fresh, smaller particles and aged, larger particles. OM concentrations were on average similar between periods when the sampling site was upwind and downwind of the freeway, though during the morning OM concentrations were higher under downwind conditions, as was the fraction of HOA.

Secondary phase formation and the microstructural evolution of surface layers during vapor phase alteration of the French SON 68 nuclear waste glass at 200{degrees}C  

SciTech Connect

The SON 68 inactive {open_quotes}R7T7{close_quotes} composition is the French reference glass for the LWR nuclear waste glass. Vapor phase alteration was used to accelerate the reaction progress of glass corrosion and to develop the characteristic suite of secondary, alteration phases. Extensive solid-state characterization (AEM/SEM/HRTEM) was completed on six inactive R7T7 waste glasses which were altered in the presence of saturated water vapor (200{degrees}C) for 91, 241, 908, 1000, 1013, and 1021 days. The AEM samples were examined in cross-section (lattice-fringe imaging, micro-diffraction, and quantitative thin-film EDS analysis). The glass monoliths were invariably covered with a thin altered rind. The layer became thicker with time: 0.5 {mu}m for 22 days; 4 {mu}m for 91 days; 6 {mu}m for 241 days; 10 {mu}m for 908 days; 26 {mu}m for 1013 days; and <35 {mu}m for 1021 days. The composite alteration layer of the SON 68 samples is at least four time less thick than that of the SRL 131 glass composition. Six distinctive zones, based on phase chemistry and microstructure, were distinguished within the well-developed surface layers. Numerous crystalline phases such as analcime, tobermorite, apatite, and weeksite were identified on the surfaces of the reacted glasses as precipitates. Two crystalline phases, Ag{sub 2}TeO{sub 3} and (Ca,Sr)Mo{sub 3}O{sub 9}(OH){sub 2}, were found within the inner zones of surface layers, and they must have nucleated in situ, indicating that Ag, Te, Sr, and Mo can be retained within the surface layer. The majority of the surface layer volume is composed of two morphologically and chemically different structures: one consists of well-crystallized fibrous smectite aggregates occurring along with cavities, the A-domain; and the other consists of poorly-crystallized regions containing needle-like smectite (montmorillonite) crystallites, a silica-rich amorphous matrix, and possibly ZrO{sub 2} particles, the B-domain.

Generativity, hierarchical action and recursion in the technology of the Acheulean to Middle Palaeolithic transition: a perspective from Patpara, the Son Valley, India.  

PubMed

The Acheulean to Middle Palaeolithic transition is one of the most important technological changes that occurs over the course of human evolution. Here we examine stone artefact assemblages from Patpara and two other excavated sites in the Middle Son Valley, India, which show a mosaic of attributes associated with Acheulean and Middle Palaeolithic industries. The bifaces from these sites are very refined and generally small, but also highly variable in size. A strong relationship between flake scar density and biface size indicates extensive differential resharpening. There are relatively low proportions of bifaces at these sites, with more emphasis on small flake tools struck from recurrent Levallois cores. The eventual demise of large bifaces may be attributed to the curation of small prepared cores from which sharper, or more task-specific flakes were struck. Levallois technology appears to have arisen out of adapting aspects of handaxe knapping, including shaping of surfaces, the utilization of two inter-dependent surfaces, and the striking of invasive thinning flakes. The generativity, hierarchical organization of action, and recursion evident in recurrent Levallois technology may be attributed to improvements in working memory. PMID:23746433

Mid- to Late Holocene climate development in Central Asia as revealed from multi-proxy analyses of sediments from Lake Son Kol (Kyrgyzstan)  

NASA Astrophysics Data System (ADS)

A mid-Holocene shift from predominantly wet to significantly drier climate conditions, attributed to the weakening of the Asian summer monsoon (ASM), is documented in numerous palaeoclimate records from the monsoon-influenced parts of Asia, e.g. the Tibetan Plateau and north- and southeastern China. In contrast, Holocene climate development in the arid regions of mid-latitude Central Asia, located north and northwest of the Tibetan Plateau, is less well-constrained but supposed to have been influenced by a complex interaction between the mid-latitude Westerlies and the ASM. Hence, well-dated and highly resolved palaeoclimate records from Central Asia might provide important information about spatio-temporal changes in the regional interplay between Westerlies and ASM and thus aid the understanding of global climate teleconnections. As a part of the project CADY (Central Asian Climate Dynamics), aiming at reconstructing past climatic and hydrological variability in Central Asia, several sediment cores were recovered from alpine Lake Son Kol (41 48'N, 75 12'E, 3016 m a. s. l.) in the Central Tian Shan of Kyrgyzstan. A radiocarbon-dated sediment sequence of 154.5 cm length, covering approximately the last 6000 years, was investigated by using a multi-proxy approach, including sedimentological, (bio)geochemical, isotopic and micropalaeontological analyses. Preliminary proxy data indicate hydrologically variable but predominantly wet conditions until ca. 5100 cal. a BP, characterized by the deposition of finely laminated organic-carbonatic sediments. In contrast to monsoonal Asia, where a distinct trend towards drier conditions is observed since the mid-Holocene, the hydrologically variable interval at Lake Son Kol was apparently followed by an only short-term dry episode between ca. 5100 and 4200 cal. a BP. This is characterized by a higher ?D of the C29 n-alkanes, probably reflecting increased evapotranspiration. Also pollen, diatom and ostracod data point towards drier climate conditions. Higher ?15N values during this period may also reflect increased evaporation but could also be related to dust input of NOx, being in agreement with high amounts of fine-grained minerogenic material. Further periods of higher ?15N values and contents of fine-grained minerogenic material occurred at 3600-3000 and 2000-1600 cal. a BP. However, as biogeochemical data indicate no further distinct dry episodes since about 4200 cal. a BP, these intervals most probably reflect increased dust deposition. Finally, a trend towards wetter climate conditions can be observed during the last ca. 1500 years, reflected by high ostracod and diatom diversity and (bio)geochemical data. The absence of a pronounced drying trend since the mid-Holocene, as observed in monsoonal Asia, is largely consistent with results from other regional palaeoclimate records and might reflect the predominant influence of the strengthening mid-latitude Westerlies on regional climate since this time.

Analytical electron microscopy study of surface layers formed on the french SON68 nuclear waste glass during vapor hydration at 200{degree}C.  

SciTech Connect

Extensive solid-state characterization (AEM/SEM/HRTEM) was completed on six SON68 (inactive R7T7) waste glasses which were altered in the presence of saturated water vapor (200{sup o}C) for 22, 91, 241, 908, 1000, 1013, and 1021 days. The samples were examined by AEM in cross-section (lattice-fringe imaging, micro-diffraction, and quantitative thin-film EDS analysis). The glass monoliths were invariably covered by a thin altered rind, and the surface layer thickness increased with increasing time of reaction, ranging from 0.5 to 30 {mu}m in thickness. Six distinctive zones, based on phase chemistry and microstructure, were distinguished within the well-developed surface layers. Numerous crystalline phases such as analcime, gyrolite, tobermorite, apatite, and weeksite were identified on the surfaces of the reacted glasses as precipitates. The majority of the surface layer volume was composed of two basic structures that are morphologically and chemically distinct: The A-domain consisted of well-crystallized fibrous smectite aggregates; and the B-domain consisted of poorly-crystallized regions containing smectite, possibly montmorillonite, crystallites and a ZrO{sub 2}-rich amorphous silica matrix. The retention of the rare-earth elements, Mo, and Zr mostly occurred within the B-domain; while transition metal elements, such as Zn, Cr, Ni, Mn, and Fe, were retained in the A-domain. The element partitioning among A-domains and B-domains and recrystallization of the earlier-formed B-domains into the A-domain smectites were the basic processes which have controlled the chemical and structural evolution of the surface layer. The mechanism of surface layer formation during vapor hydration are discussed based on these cross-sectional AEM results.

Flow-through dissolution experiments were carried out on the SON68 glass梩he inactive analog of the French high-level waste glass梐t 90 癈 and pH = 9 over a silica saturation interval [0-150 ppm Si(aq)]. Two types of specimens were subjected to dissolution studies: powders (249-150, 149-75 or 74-45 ?m diameter size fractions) or monoliths (1 cm 1 cm 4 mm). At each Si concentration interval individual coupon and glass powder experiments were run at the same flow-to-surface area (q/S) conditions. Under dilute solution conditions, the dissolution rate becomes independent of q/S and define the forward rate of reaction of 0.30 g/(m2 d). Dissolution rates of powders normalized on either a geometric or a B.E.T. surface area basis were compared to rates determined on monoliths. In every case, the geometric surface area normalized rates matched those of the monoliths, conclusively showing that B.E.T. normalized rates are too low by a factor of 3. In Si-free solutions changes in flow rates resulted in differences in Al released to solution (50 to 3140 ppb), correlating inversely with dissolution rates. Si was added to input solutions and kept constant ("direct"), but in select experiments Si concentrations were above target concentrations, and then dropped to their target values ("indirect"). Both "direct" and "indirect" Si addition experiments yielded identical dissolution rates within experimental uncertainty. Progressive addition of Si to the input solution caused a decrease in rates from 0.30 to 0.0020 g/(m2 d), or a factor of 150, but the decrease is strongly non-linear with respect to Si. These data are inconsistent with simple models relating glass dissolution to the chemical affinity of reaction.

GIS methodology for quantifying channel change in Las Vegas, Nevada  

USGS Publications Warehouse

This study applies spatial analyses to examine the consequences of accelerated urban expansion on a hydrologic system over a period of 24 years. Three sets of historical aerial photos are used in a GIS analysis to document the geomorphic history of Las Vegas Wash, which drains the rapidly growing Las Vegas urban area in southern Nevada. New spatial techniques are introduced to make quantitative measurements of the erosion at three specific time intervals in the hydrologic evolution of the channel and floodplain. Unlike other erosion studies that use two different elevation surfaces to assess erosion, this study used a single elevation surface to remove systematic and nonsystemic elevation errors. The spatial analysis quantifies channel changes for discrete time periods, calculates erosion volumes, and provides a foundation to examine how the specific mechanisms related to urban expansion have affected Las Vegas Wash. The erosion calculated over 24 years is the largest documented sediment loss attributed to the effect of rapid urban growth. ?? 2007 American Water Resources Association.

Revision curricular a partir de un analisis comparativo de las discrepancias en los curriculos de una escuela de optometria en Puerto Rico con las competencias requeridas para las agencias de revalida y acreditacion 2004  

NASA Astrophysics Data System (ADS)

El proposito de esta investigacion, un estudio cualitativo de caso, fue comparar y contrastar el curriculo vigente de la Escuela de Optometria de la UIAPR con las competencias y estandares requeridos por las agencias de acreditacion y de revalida. Con este proposito, decidimos realizar una revision y un analisis de documentos: el prontuario de cada uno de los cursos de los curriculos implantados en el 1993 y en el 2001; las competencias y estandares establecidos por las agencias de revalida y de acreditacion; y las estadisticas en las que se analiza el porcentaje de estudiantes que aprueban cada una de las partes de los examenes de revalida entre el 1998 al 2003. Se realizaron entrevistas dirigidas para dar apoyo y complementar la revision y el analisis de estos documentos. Los participantes de las entrevistas fueron tres estudiantes de la clase de optometria del 2004 (ultima clase del curriculo del 1993); tres estudiantes de la clase de optometria del 2005 (primera clase graduanda del curriculo vigente) y tres profesores y/o directores de los Departamentos de Ciencias Basicas, Ciencias Clinicas y Cuidado al Paciente. Esta investigacion se enmarco en el modelo de evaluacion curricular de discrepancia de Malcolm Provus y en el modelo de desarrollo basado en competencias. Uno de los hallazgos mas importantes del estudio es que los cambios que se implantaron al curriculo del 2001 no han logrado que los estudiantes mejoren su ejecucion en los examenes de revalida. Por otro lado, se encontro que el curriculo vigente atiende completamente los estandares de la practica de Optometria, pero no las competencias. Esta informacion fue validada mediante el uso de una tabla de cotejo para el analisis de los cursos y de la informacion obtenida de las entrevistas. El estudio determina y concluye que existen discrepancias entre los prontuarios de los cursos del curriculo y las competencias requeridas por la agencia de revalida. Segundo, que el Departamento de Ciencias Basicas es el que presenta mas deficiencias en el desarrollo de las competencias. El investigador recomienda disenar e implantar un curriculo basado en competencias y proveer formacion en didactica y procesos de aprendizaje a los profesores.

We generate the 2-dimensional high-resolution density field of galaxies of the Early Data Release of the Sloan Digital Sky Survey and the Las Campanas Redshift Survey with a smoothing length 0.8 Mpc/h to extract clusters and groups of galaxies, and a low-resolution field with a smoothing length 10 Mpc/h to extract superclusters of galaxies. We investigate properties of density field clusters and superclusters and compare the properties of these clusters and superclusters with those of Abell clusters, and superclusters found on the basis of Abell clusters. We found that clusters in a high-density environment have a luminosity a factor of 5 - 10 higher than in a low-density environment. Clusters and superclusters in the Northern slice of SDSS are much richer than those in the Southern slice.

LAS homolog distribution shift during wastewater treatment and composting ecological implications  

SciTech Connect

The behavior of LAS (linear alkylbenzene sulfonate) in different environmental compartments was studied through wastewater treatment process steps in sewage treatment plants of Alicante and Benidorm (activated sludge type) as well as in Guardamar (lagoons). The fate of LAS, using a specific HPLC method, was monitored during treatment sludge compostage and soil amendment operations. Finally, the marine sediments close to a submarine wastewater sewer outfall were analyzed. The results show significant differences between distribution of LAS homologs in water and solids (sludges, sediments, and soils), as compared to the original distribution in detergent formulations, yielding a lower LAS average molecular weight in water samples. The change observed in the homolog distribution of LAS implies a reduction in the toxicity to Daphnia, because a lower average molecular weight of LAS is less toxic.

La transpiraci贸n es la p茅rdida de agua en forma de vapor por las plantas. El agua es absorbida del suelo por las ra铆ces y transportada en forma l铆quida por el xilema hacia las hojas. En las hojas, unos peque駉s poros permiten que el agua (H2O) escape a la atm贸sfera en forma de vapor, al tiempo que se permite la entrada de bi贸xido de carbono (CO2) para la fotos铆ntesis. De toda el agua absorbida por las plantas, menos del 5% es retenida y utilizada para crecimiento y almacenamiento. En esta lecci贸n se explicar谩 porque las plantas pierden tanta agua, la ruta que 茅sta sigue dentro de la planta, como pudieran las plantas controlar la p茅rdida excesiva de agua y como las condiciones ambientales influyen en la p茅rdida de agua por las plantas.

Stationary Phase-Specific Virulence Factor Overproduction by a lasR Mutant of Pseudomonas aeruginosa  

PubMed Central

Secreted virulence factors of the human pathogen Pseudomonas aeruginosa are often under quorum sensing control. Cells lacking the quorum-sensing regulator LasR show reduced virulence factor production under typical laboratory conditions and are hypo-virulent in short-term animal infection models, yet lasR mutants are frequently associated with long-term infection in cystic fibrosis patients. Here, I show that in stationary-phase or slow-growth conditions, lasR cells continuously and strongly produce the important virulence factor pyocyanin while wild-type cells do not. Pyocyanin overproduction by lasR cells is permitted by loss of repression by RsaL, a LasR-dependent negative regulator. lasR cells also contribute pyocyanin in mixed cultures, even under 揷heating conditions where they depend on their wild-type neighbors for nutrients. Finally, some clinical P. aeruginosa isolates with lasR mutations can overproduce pyocyanin in the laboratory. These results imply that slow-growing clinical populations of lasR cells in chronic infections may contribute to virulence by producing pyocyanin under conditions where lasR+ cells do not.

Optimization of linear alkylbenzene sulfonate (LAS) degradation in UASB reactors by varying bioavailability of LAS, hydraulic retention time and specific organic load rate.  

PubMed

Degradation of linear alkylbenzene sulfonate (LAS) in UASB reactors was optimized by varying the bioavailability of LAS based on the concentration of biomass in the system (1.3-16 g TS/L), the hydraulic retention time (HRT), which was operated at 6, 35 or 80 h, and the concentration of co-substrates as specific organic loading rates (SOLR) ranging from 0.03-0.18 g COD/g TVS.d. The highest degradation rate of LAS (76%) was related to the lowest SOLR (0.03 g COD/g TVS.d). Variation of the HRT between 6 and 80 h resulted in degradation rates of LAS ranging from 18% to 55%. Variation in the bioavailability of LAS resulted in discrete changes in the degradation rates (ranging from 37-53%). According to the DGGE profiles, the archaeal communities exhibited greater changes than the bacterial communities, especially in biomass samples that were obtained from the phase separator. The parameters that exhibited more influence on LAS degradation were the SOLR followed by the HRT. PMID:23196232

Surveys, Temporal Variability, and the Las Cumbres Observatory Global Telescope  

NASA Astrophysics Data System (ADS)

Upcoming wide-field surveys such as Pan-STARRS, LSST, and Skymapper will detect large numbers of objects that vary photometrically, or that move. These objects will include small bodies in the solar systema, eclipsing binary stars, transiting extrasolar planets, pulsating stars, dwarf novae, novae, supernovae, active galactic nuclei, and quite possibly other transient phenomena for which we have no names as yet. Although they will be a fertile source of such transient detections, wide-field surveys themselves ordinarily will have neither the observing cadence nor the (e.g., spectroscopic) observing capabilities to perform adequate follow-up observations of these variable objects. The Las Cumbres Observatory Global Telescope (LCOGT) will be a global network of moderate-aperture (2m and smaller) telescopes, instrumented and interconnected so as to facilitate such in-depth variability studies. The LCOGT now operates the two 2m Faulkes Telescopes: FT North located on the island of Maui, and FT South at the Siding Spring site in Australia. These telescopes will anchor a network of about 7 clusters of 1m-class telescopes, each cluster containing 4 telescopes. First-light instruments will provide visible-light and NIR imaging; spectroscopic capabilities will come later, and will likely include both low- and high-resolution visible-light spectrographs. Scheduling and coordination of observations will be provided from a central site, in pursuit of a single set of scientific goals.

Assembly Bias of Dark Matter Halos in LasDamas  

NASA Astrophysics Data System (ADS)

Assembly bias of dark matter halos refers to the phenomenon in which the clustering of dark matter halos of a fixed mass depends significantly on a second property, in particular: age, concentration or spin. This discovery suggests a challenge for halo occupation distribution and other models that connect galaxy properties solely to halo mass. To investigate assembly bias we use the Large Suite of Dark Matter Simulations (LasDamas) to calculate the large-scale clustering of distinct halos as a function of a variety of properties including mass. We first investigate whether some property other than mass is better able to single-handedly predict clustering, i.e., eliminate the need for a second parameter, but we find no such property. Noting that for many halos the current mass is significantly lower than the peak mass it attained over its history, we revisit assembly bias using only halos that have maintained a significant fraction of their peak mass. We find that the dependence of clustering on a second halo parameter is significantly reduced without the inclusion of these high mass-loss halos. This strongly suggests that part of the theoretical explanation for assembly bias may be that a large fraction of halos do not continually grow in mass, as assumed in spherical collapse models, but instead lose significant amounts of their mass at later times due to interactions with other halos.

Managing Floods and Resources at the Arroyo Las Positas  

SciTech Connect

Engineers and water resource professionals are challenged with protecting facilities from flood events within environmental resource protection, regulatory, and economic constraints. One case in point is the Arroyo Las Positas (ALP), an intermittent stream that traverses the Lawrence Livermore National Laboratory (LLNL) in Livermore, California. Increased runoff from post-drought rainfall, upstream development, and new perennial discharges from LLNL activities have resulted in increased dry weather flows and wetland vegetation. These new conditions have recently begun to provide improved habitat for the federally threatened California red-legged frog (Rana aurora draytonii; CRLF), but the additional vegetation diminishes the channel's drainage capacity and increases flood risk. When LLNL proposed to re-grade the channel to reestablish the 100-year flood capacity, traditional dredging practices were no longer being advocated by environmental regulatory agencies. LLNL therefore designed a desilting maintenance plan to protect LLNL facility areas from flooding, while minimizing impacts to wetland resources and habitat. The result was a combination of structural upland improvements and the ALP Five Year Maintenance Plan (Maintenance Plan), which includes phased desilting in segments so that the entire ALP is desilted after five years. A unique feature of the Maintenance Plan is the variable length of the segments designed to minimize LLNL's impact on CRLF movement. State and federal permits also added monitoring requirements and additional constraints on desilting activities. Two years into the Maintenance Plan, LLNL is examining the lessons learned on the cost-effectiveness of these maintenance measures and restrictions and reevaluating the direction of future maintenance activities.

[The son of man. Freud's Oedipus myth].  

PubMed

In formulating his psychology of the unconscious, Freud makes constant reference to Sophocles' version of the Oedipus myth. The author provides detailed proof of the fundamental differences between the two versions, demonstrating that Freud's interpretation does violence to the source. Bollack marshals impressive evidence to substantiate his contention that from the early letters to Fliess all the way up to Moses and Monotheism Freud's sole concern was to point up the ubiquitous power of the unconscious (incestual desire, patricide) within the "holy" (nuclear) family, whereas Sophocles was preoccupied with an entirely different problem. In Bollack's view, Oedipus rex is the drama of the self-destruction of a royal family, a drama in which incest and murder have no very essential significance. Freud, by contrast, set out to de-mystify the fate that dogs the royal family from one generation to the next and to naturalise it into a form of unconscious behaviour--a tendency which Bollack sees as deriving from the tradition of the "drama of destiny", a genre prevalent in the 19th century.

A New Transcriptional Repressor of the Pseudomonas aeruginosa Quorum Sensing Receptor Gene lasR  

PubMed Central

Pseudomonas aeruginosa pathogenic potential is controlled via multiple regulatory pathways, including three quorum sensing (QS) systems. LasR is a key QS signal receptor since it acts as a global transcriptional regulator required for optimal expression of main virulence factors. P. aeruginosa modulates the QS response by integrating this cell density-dependent circuit to environmental and metabolic cues. Hence, QS also controls the adaptation to challenging environmental niches, such as infection sites. However, little is known about the molecular mechanisms connecting QS and other signalling pathways. In this work, DNA-affinity chromatography was used to identify new lasR transcriptional regulators. This approach led to the identification and functional characterization of the TetR-like transcriptional repressor PA3699. This protein was purified and shown to directly bind to the lasR promoter region in vitro. The induction of PA3699 expression in P. aeruginosa PAO1 cultures repressed lasR promoter activity and the production of LasR-dependent virulence factors, such as elastase, pyocyanin, and proteases. These findings suggest a role for PA3699 in P. aeruginosa pathogenicity. P. aeruginosa genome encodes at least 38 TetR-family proteins, and PA3699 is the eighth member of this group functionally characterized so far and the first one shown to bind the lasR promoter in vitro.

Global position analysis of the Pseudomonas aeruginosa quorum-sensing transcription factor LasR  

PubMed Central

Summary In Pseudomonas aeruginosa quorum sensing (QS), the transcriptional regulator LasR controls the expression of more than 300 genes. Several of these genes are activated indirectly via a second, subordinate QS regulator, RhlR. Conserved sequence elements upstream of individual other genes have been shown to bind LasR in vitro. To comprehensively identify all regions that are bound by LasR in vivo, we employed chromatin immunoprecipitation in conjunction with microarray analysis. We identified 35 putative promoter regions that direct the expression of up to 74 genes. In vitro DNA binding studies allowed us to distinguish between cooperative and non-cooperative LasR binding sites, and allowed us to build consensus sequences according to the mode of binding. Five promoter regions were not previously recognized as QS-controlled. Two of the associated transcript units encode proteins involved in the cold-shock response and in Psl exopolysaccharide synthesis, respectively. The LasR regulon includes seven genes encoding transcriptional regulators, while secreted factors and secretion machinery are the most overrepresented functional categories overall. This supports the notion that the core function of LasR is to coordinate the production of extracellular factors, although many of its effects on global gene expression are likely mediated indirectly by regulatory genes under its control.

Lsb1 Is a Negative Regulator of Las17 Dependent Actin Polymerization Involved in Endocytosis  

PubMed Central

The spatial and temporal regulation of actin polymerization is crucial for various cellular processes. Members of the Wiskott朅ldrich syndrome protein (WASP) family activate the Arp2/3-complex leading to actin polymerization. The yeast Saccharomyces cerevisiae contains only one WASP homolog, Las17, that requires additional factors for its regulation. Lsb1 and Lsb2/Pin3 are two yeast homologous proteins bearing an SH3 domain that were identified as Las17-binding proteins. Lsb2/Pin3 that promotes prion induction was suggested to link this prion formation to the actin cytoskeleton. However, the cellular role of Lsb1 and the molecular function of both Lsb1 and Lsb2 remain unknown. In this study, we show that Lsb1 and/or Lsb2 full-length proteins inhibit Las17-mediated actin polymerization in vitro, Lsb2 being a less potent inhibitor of Las17 activity compared to Lsb1. Addition of Lsb1 or Lsb2 to the corresponding full-length Lsb1/2 further inhibits Las17 activity. Lsb1 and Lsb2 form homo- and hetero-oligomeric complexes suggesting that these two proteins could regulate Las17 activity via dimerization or cooperative binding. In vivo, overexpressed Lsb1 and Lsb2 proteins cluster Las17-CFP in few cytoplasmic punctate structures that are also positive for other Arp2/3-dependent actin polymerization effectors like Sla1 or Abp1. But, only Lsb1 overexpression blocks the internalization step of receptor-mediated endocytosis. This shows a specific function of Lsb1 in endocytosis. PMID:23577202

Identification of methyl triclosan and halogenated analogues in male common carp (Cyprinus carpio) from Las Vegas Bay and semipermeable membrane devices from Las Vegas Wash, Nevada  

USGS Publications Warehouse

Methyl triclosan and four halogenated analogues have been identified in extracts of individual whole-body male carp (Cyprinus carpio) tissue that were collected from Las Vegas Bay, Nevada, and Semipermeable Membrane Devices (SPMD) that were deployed in Las Vegas Wash, Nevada. Methyl triclosan is believed to be the microbially methylated product of the antibacterial agent triclosan (2, 4, 4'-trichloro-4-hydroxydiphenyl ether, Chemical Abstract Service Registry Number 3380-34-5, Irgasan DP300). The presence of methyl triclosan and four halogenated analogues was confirmed in SPMD extracts by comparing low- and high-resolution mass spectral data and Kovats retention indices of methyl triclosan with commercially obtained triclosan that was derivatized to the methyl ether with ethereal diazomethane. The four halogenated analogues of methyl triclosan detected in both whole-body tissue and SPMD extracts were tentatively identified by high resolution mass spectrometry. Methyl triclosan was detected in all 29 male common carp from Las Vegas Bay with a mean concentration of 596????g kg- 1 wet weight (ww) which is more than an order of magnitude higher than previously reported concentrations in the literature. The halogenated analogs were detected less frequently (21%-76%) and at much lower concentrations (< 51????g kg- 1 ww). None of these compounds were detected in common carp from a Lake Mead reference site in Overton Arm, Nevada.

A reinterpretation of the Pleistocene human and faunal association at Las Buitreras Cave, Santa Cruz, Argentina  

NASA Astrophysics Data System (ADS)

The faunal assemblage recovered from Layers VIII-VII at Las Buitreras Cave has been considered as associated with human artifacts. On that basis, the previous analysis had concluded that human hunters had exploited ground sloths at the end of the Pleistocene. A reanalysis of the bones as well as the rest of the evidence suggests that there is no basis for that conclusion. On the contrary, it is suggested here that the lower layers at Las Buitreras are the result of the use of the cave as a den by ground sloths.

Las Vegas' Sahara Hotel and Casino closing after more than 58 yearshttp://news.blogs.cnn.com/2011/05/16/las-vegas-sahara-hotel-and-casino-closing-after-more-than-58-years/?hpt=C2Las Vegas Historyhttp://www.lasvegassun.com/history/Southern Nevada: The Boomtown Yearshttp://digital.library.unlv.edu/boomtown/Vegas Tripping: Implosionshttp://www.vegastripping.com/implosions/The Neon Museumhttp://neonmuseum.org/All that glitters is not gold, and when it comes to the glittering lights of the Vegas Strip, nothing is permanent. This weekend, the Sahara hotel saw its last guests leave as it ended its 58-year run on the Strip. The hotel was the brainchild of one Milton Prell, a former jewelry salesman who ran a bingo parlor in Montana. In 1952, he opened the Sahara, which he envisioned as a "jewel of the desert". The Sahara was the sixth hotel on the Strip, and with its fantastical Congo Room supper club and Casbar Lounge, it was a flourishing part of the "ring-a-ding-ding" 1950s and 1960s scene in Las Vegas. Characters who were part of the Strip's history included legendary entertainers Ray Bolger, Donald O'Connor, and Louis Prime, who performed there for years with his wife, Keely Smith. While plans for the site are in flux, it is hoped that some of the Sahara's iconic neon signs will end up in the nearby Neon Museum.The first link will take visitors to a nice article from this Saturday's Las Vegas Sun about the closing of the Sahara. The second link leads to piece from CNN's blog which also talks about the recent closing of this famed Strip stalwart. The third link will whisk users away to a terrific site from the Las Vegas Sun which chronicles the highs and lows of the Strip's history. Moving on, the fourth link leads to a nice digital collection from the University of Nevada, Las Vegas which documents the boom years of Southern Nevada through images, documents, and other archival items. The fifth link leads to a rather raucous and fun archive of Strip hotel implosions captured for posterity. Finally, the last link leads to the homepage of The Neon Museum in Las Vegas, which celebrates neon culture in all of its glory.

Bioconcentration of the anionic surfactant linear alkylbenzene sulfonate (LAS) in the marine shrimp Palaemonetes varians: a radiotracer study.  

PubMed

Uptake and depuration kinetics of dissolved [(14)C]C??-6-linear alkylbenzene sulfonate (LAS) were determined in the shrimp Palaemonetes varians using environmentally relevant exposure concentration. The shrimp concentrated LAS from seawater with a mean BCF value of 120 L kg(-1) after a 7-day exposure. Uptake biokinetics were best described by a saturation model, with an estimated BCFss, of 159 34 L kg(-1), reached after 11.5 days. Shrimp weight influenced significantly BCF value with smaller individuals presenting higher affinity to LAS. To the light of a whole body autoradiography, major accumulation of LAS occurred in the cephalothorax circulatory system (gills, heart, hepatopancreas) and ocular peduncle, but not in the flesh, limiting potential transfer to human consumers. LAS depuration rate constant value of the shrimp was 1.18 0.08 d(-1) leading to less than 1% of remaining LAS in its tissues after 8 days of depuration. PMID:25016418

Geophysical constraints on the location and geometry of the Las Vegas Shear Zone, Nevada  

USGS Publications Warehouse

We model the basin configuration beneath Las Vegas Valley, Nevada, on the basis of gravity, drillhole, and seismic reflection data. We locate and characterize the various strands of the Las Vegas Valley Shear Zone (LVVSZ) by variations in basin thickness beneath the valley. The pre-Tertiary bedrock surface is complex, with subbasins buried beneath the flat alluvial surface of the valley. We suggest that these basins are formed from transtensional strain. Subbasins elongated N70??W and N50??W are interpreted as strike-slip basins. The deepest subbasin is 5 km west of Frenchman Mountain and strikes N40??E. This basin probably formed by combined movement on nonparallel strands of the LVVZ and an earlier episode of normal faulting. The basin thickness map constrains the minimum depth of the inferred detachment fault beneath Las Vegas Valley to at least 4 km. Seismic reflection data do not image a detachment fault in the upper 10 km beneath Las Vegas Valley. Our results also illustrate the utility of gravity in determining basinal structures and providing a three-dimensional perspective in areas with limited seismic reflection control.

Isolation of the Autoinducer-Quenching Strain that Inhibits LasR in Pseudomonas aeruginosa  

PubMed Central

Quorum sensing (QS) has been recognized as a general phenomenon in microorganisms and plays an important role in many pathogenic bacteria. In this report, we used the Agrobacterium tumefaciens biosensor strain NT1 to rapidly screen for autoinducer-quenching inhibitors from bacteria. After initial screening 5389 isolates obtained from land and beach soil, 53 putative positive strains were identified. A confirmatory bioassay was carried out after concentrating the putative positive culture supernatant, and 22 strains were confirmed to have anti-LasR activity. Finally, we determined the strain JM2, which could completely inhibit biofilm formation of Pseudomonas aeruginosa PAO1, belonged to the genus Pseudomonas by analysis of 16S rDNA. Partially purified inhibitor factor(s) F5 derived from culture supernatants specifically inhibited LasR-controlled elastase and protease in wild type P. aeruginosa PAO1 by 68% and 73%, respectively, without significantly affecting growth; the rhl-controlled pyocyanin and rhamnolipids were inhibited by 54% and 52% in the presence of 100 ?g/mL of F5. The swarming motility and biofilm of PAO1 were also inhibited by F5. Real time RT-PCR on samples from 100 ?g/mL F5-treated P. aeruginosa showed downregulation of autoinducer synthase (LasRI and rhlI) and cognate receptor (lasR and rhlR) genes by 50%, 28%, 48%, and 29%, respectively. These results provide compelling evidence that the F5 inhibitor(s) interferes with the las system and significantly inhibits biofilm formation. PMID:24736783

Effect of linear alkylbenzene sulphonate (LAS) on non-specific defence mechanisms in rainbow trout (Oncorhynchus mykiss).  

PubMed

Linear alkylbenzene sulphonate (LAS) is among the most widely disseminated xenobiotics to enter waste streams and the aquatic environment. In the present investigation, we present a novel approach to evaluate in toxicity of LAS. The effects of sublethal levels (0.2 and 0.4 mg/l) of LAS on non-specific immune system, phagocytosis, respiratory burst and lyzosyme activity, and specific growth rate in the rainbow trout, Oncorhynchus mykiss, during a 54-day exposure were examined by a static bioassay test procedure. The phagocytic activity of leukocytes from fish exposed to 0.4 mg/l LAS statistically decreased compared with the control fish values. No significant reductions were observed in the extra-intracellular respiratory burst and lysozyme activities after exposure to LAS at any of the concentrations tested. The final body weight in fish groups exposed to the LAS were found to be significantly lower than in the control. The specific growth rate results also supported the result above. The results of this study showed sublethal doses (0.2-0.4 mg/l) of LAS caused to statistically insignificant suppression of non-specific immune system mechanisms excluding phagocytosis in fish at laboratory conditions. These doses of LAS may produce potential synergism on immune system when presented with other environmental pollutants. PMID:15642641

Candida albicans-produced farnesol stimulates Pseudomonas quinolone signal production in LasR-defective Pseudomonas aeruginosa strains  

PubMed Central

Candida albicans has been previously shown to stimulate the production of Pseudomonas aeruginosa phenazine toxins in dual-species colony biofilms. Here, we report that P. aeruginosa lasR mutants, which lack the master quorum sensing system regulator, regain the ability to produce quorum-sensing-regulated phenazines when cultured with C. albicans. Farnesol, a signalling molecule produced by C. albicans, was sufficient to stimulate phenazine production in LasR? laboratory strains and clinical isolates. P. aeruginosa ?lasR mutants are defective in production of the Pseudomonas quinolone signal (PQS) due to their inability to properly induce pqsH, which encodes the enzyme necessary for the last step in PQS biosynthesis. We show that expression of pqsH in a ?lasR strain was sufficient to restore PQS production, and that farnesol restored pqsH expression in ?lasR mutants. The farnesol-mediated increase in pqsH required RhlR, a transcriptional regulator downstream of LasR, and farnesol led to higher levels of N-butyryl-homoserine lactone, the small molecule activator of RhlR. Farnesol promotes the production of reactive oxygen species (ROS) in a variety of species. Because the antioxidant N-acetylcysteine suppressed farnesol-induced RhlR activity in LasR? strains, and hydrogen peroxide was sufficient to restore PQS production in las mutants, we propose that ROS are responsible for the activation of downstream portions of this quorum sensing pathway. LasR mutants frequently arise in the lungs of patients chronically infected with P. aeruginosa. The finding that C. albicans, farnesol or ROS stimulate virulence factor production in lasR strains provides new insight into the virulence potential of these strains. PMID:20656785

Geologic Interpretation of the Las Vegas Valley Based on Industry Seismic Reflection Data  

NASA Astrophysics Data System (ADS)

Las Vegas Valley, NV is located in the southern Basin and Range Province where the basin was formed by the Las Vegas Valley Shear Zone as well as by several thrust and normal faulting events that occurred by Cenozoic time. The geology and tectonic setting in the Las Vegas region is poorly understood given the fact that many structures have been covered by the constant growth of the City. National studies of ground motion and amplification of seismic energy placed Nevada third in the list of states having the potential for loss of life and property due to earthquakes. The Las Vegas area has a high potential for strong ground shaking due its thick basin fill and associated amplification. Due to the amplification effects within the Valley, moderate nearby quakes or large distant quakes will produce a large amount of damage in the Valley. Las Vegas, though not known for its earthquakes, has numerous micro quakes and an active seismic history. In a study using HAZUS to predict damage associated with a M6.9 earthquake, the loss would be billions of dollars with thousands of lives lost. Long-term economic loss would be in the several billions of dollars. Recently, several normal faults, which have the potential to produce a M6.5 to 7.0 earthquake, were reclassified as active tectonic fault with Quaternary movement. As a result, there has been increased effort to understand the Las Vegas Valley and to assess its potential for seismic hazards. One such effort included acquiring industry reflection profiles that cross the Valley. In the 1980's, north/south and east/west trending reflection lines with intersecting tie points were placed between Frenchman Mountain to the East and Spring Mountains to produce seismic profiles using Vibroseis. The profiles, which are over 200 kilometers in length and extend down to 5 s in time or approximately 15 km depth, will provide a tie between the surface work that is currently being conducted and the crustal velocity models that are being calculated to produce a seismic hazard potential for the Las Vegas Valley. The quality of the Vibroseis data is very high. We have been able to locate the basin/bedrock contact as well as several faults that cut the sections. All of which have been mapped on the shot point map. Most of the faults appear to be normal faults listric in character that trend north-south paralleling the structure of the southern Basin and Range. Basin geometry and associated minor folding, which have been truncated by minor faulting, can be seen across the profiles. Some faults can be seen as tectonic in origin while others are merely subsidence faulting from basin settling. With this new data we will identify structures that could potentially focus energy in the sub-surface adding to our growing knowledge of the basin geometry. In addition, this data will be incorporated into the seismic hazard model that is being developed for the Las Vegas Valley and will provide very detailed geologic information that has not been previously available.

Comenditic and pantelleritic ash-flow tuffs from Volcan Las Navajas, Nayarit, Mexico  

SciTech Connect

Two distinctive ash-flow tuffs occur around the base of Volcan Las Navajas, a Pleistocene trachyte - peralkaline rhyolite center located in the northwestern segment of the Mexican Volcanic belt. The lower ash-flow unit is locally up to 65 m thick, is lithic rich and contains pumice blocks of comenditic rhyolite. The unit is not extensively exposed, and thus its areal extent and volume cannot be determined. Its chemical characteristics and stratigraphic relationship to other products erupted from Las Navajas suggest that it is related to the formation of the older of the two calderas which occur on Las Navajas. Unconformably overlying this unwelded ash-flow is a pantelleritic airfall pumice unit which is locally welded. This airfall unit is conformably overlain by a welded as-flow tuff that contains fiamme of pantelleritic composition (72 %SiO/sub 2/, 8% FeO*, 900 ppm Zr, agpaitic index of 1.7) as well as pumice blocks that show evidence of various degrees of mixing between pantellerite and trachyte. This suggests eruption from a chemically zoned magma chamber. This unit is locally up to 20 m thick, although its top has been removed by erosion. It is found on all sides of Las Navajas except on the south where it may be covered by Volcan Sanganguey, a Pleistocene to Recent calc-alkaline volcano. The welded ash-flow has been dated by K - Ar at 0.2+/-0.1 m.y. Stratigraphically and chemically this ash-flow appears to be related to the formation of younger of the two calderas.

The Impact of Urban Development on the Water Quality in the Las Vegas Watershed  

NASA Astrophysics Data System (ADS)

Las Vegas, one of the fastest growing cities in the nation, must have its water strictly monitored for quality as well as degree of pollution. Samples at various sites were collected to analyze the current pollution status of our water bodies (in both residential and urban settings) in the Las Vegas watershed. These gathered samples (sediment and water) were collected and analyzed for measuring total phosphorus, total organic carbon, trace metal contents, i.e., selenium, arsenic, mercury and lead, as well as pathogens, i.e., E-coli and total coliform counts. The concentrations of various pollutions will be compared among different sites as well as natural local sites (due to the natural occurrence of a few trace metals and normal levels of other measurements) and analyzed for spatial distribution for source identification and for elucidating the cause and consequence. Preliminary analyses of the results indicate that nonpoint source pollutions (golf courses, construction sites, etc.) have larger impacts than point source pollutions such as wastewater treatment effluents. This study will help understand and evaluate the degradation of the water quality caused by the increase of human actions in recent years in Las Vegas.

Quantifying multi-temporal urban development characteristics in Las Vegas from Landsat and ASTER data  

USGS Publications Warehouse

Urban development has expanded rapidly in Las Vegas, Nevada of the United States, over the last fifty years. A major environmental change associated with this urbanization trend is the transformation of the landscape from natural cover types to increasingly anthropogenic impervious surface. This research utilizes remote sensing data from both the Landsat and Terra-Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instruments in conjunction with digital orthophotography to estimate urban extent and its temporal changes by determining sub-pixel impervious surfaces. Percent impervious surface area has shown encouraging agreement with urban land extent and development density. Results indicate that total urban land-use increases approximately 110 percent from 1984 to 2002. Most of the increases are associated with medium-to high-density urban development. Places having significant increases in impervious surfaces are in the northwestern and southeastern parts of Las Vegas. Most high-density urban development, however, appears in central Las Vegas. Impervious surface conditions for 2002 measured from Landsat and ASTER satellite data are compared in terms of their accuracy. ?? 2008 American Society for Photogrammetry and Remote Sensing.

Nondegraded metabolites arising from the biodegradation of commercial linear alkylbenzenesulfonate (LAS) surfactants in a laboratory trickling filter  

SciTech Connect

The degradation of a commercial linear alkylbenzenesulfonate (LAS) surfactant was examined kinetically in a trickling filter, which allowed simultaneous chemical determinations in the aqueous phase (e.g., DOC) and in the gas phase (CO{sub 2}). About 60% of the carbon applied as LAS was released as CO{sub 2}, whereas 15% remained as DOC in the eluate of acclimated trickling filters. The biomass was analyzed after the experiment, and it was found to have sorbed about 23 mg LAS/g of dry biomass; this represented about 3% of the LAS applied to the filter. The LAS and the eluates from the trickling filter were further analyzed by HPLC and UV and IR spectrometry. The residual carbon from acclimated filters contained no LAS-like material (HPLC), which was obviously subject to quantitative biotransformation. The residual material comprised > 50 polar metabolites, some of whose UV spectra differed from that of LAS, and most or all of which were sulfonated. These nondegraded metabolites included carboxylated dialkyltetralinesulfonates and sulfophenylcarboxylates. These residual materials showed no detectable toxicity to algae or Daphnia, and did not significantly lower the surface tension of water.

Growth phenotypes of Pseudomonas aeruginosa lasR mutants adapted to the airways of cystic fibrosis patients.  

PubMed

The opportunistic pathogen Pseudomonas aeruginosa undergoes genetic change during chronic airway infection of cystic fibrosis (CF) patients. One common change is a mutation inactivating lasR, which encodes a transcriptional regulator that responds to a homoserine lactone signal to activate expression of acute virulence factors. Colonies of lasR mutants visibly accumulated the iridescent intercellular signal 4-hydroxy-2-heptylquinoline. Using this colony phenotype, we identified P. aeruginosa lasR mutants that emerged in the airway of a CF patient early during chronic infection, and during growth in the laboratory on a rich medium. The lasR loss-of-function mutations in these strains conferred a growth advantage with particular carbon and nitrogen sources, including amino acids, in part due to increased expression of the catabolic pathway regulator CbrB. This growth phenotype could contribute to selection of lasR mutants both on rich medium and within the CF airway, supporting a key role for bacterial metabolic adaptation during chronic infection. Inactivation of lasR also resulted in increased beta-lactamase activity that increased tolerance to ceftazidime, a widely used beta-lactam antibiotic. Loss of LasR function may represent a marker of an early stage in chronic infection of the CF airway with clinical implications for antibiotic resistance and disease progression. PMID:17493132

Distribution and origin of dissolved gases of groundwaters at Las Ca馻das aquifer, Tenerife, Canary Islands  

NASA Astrophysics Data System (ADS)

Volcanic aquifers commonly trap an important fraction of the main soluble components of fluids released from volcanic-hydrothermal system (CO2, SO2, H2S, HCl, HF, etc.). In particular, the interactions between volcanic gases and volcanic aquifers have been studied through hydrogeochemical parameters, as major and minor ions contents and dissolved gases in groundwaters. In the context of hydrogeochemical studies applied to active volcanic areas, studies of dissolved gases species in groundwater could be a useful tool to better understand the subsurface processes as gas-water-rock interaction or to strengthen the geochemical seismic-volcanic surveillance programs. In this work, we report the results of the geochemical characterization of dissolved gases (N2, O2, Ar, CO2, CH4, CO, H2, He, 222Rn, ?13CTDIC) in 96 groundwater samples from Las Ca馻das aquifer (around Teide volcano) between May and October, 2006. The main aims of this work are: (1) to determine the background level of magmatic gas input in the aquifer during quiescent periods, (2) to better define the origin of dissolved gases in Las Ca馻das aquifer, specially CO2, (3) to evaluate the gas-water-rock interaction processes occurring at depth, and (4) to delineate high permeable pathway of upward migration of volcanic-hydrothermal gases. In general, the dissolved gas phase in groundwaters of Las Ca馻das aquifer is relatively enriched in endogenous gases (CO2, He and H2) while it is relatively depleted in atmospheric gases (N2, O2 and Ar). N2-O2-CO2 triangular diagram shows that dissolved gases in most of analyzed groundwater are variable mixtures of CO2-rich fluids from the volcanic-hydrothermal system (as represent the Teide fumaroles) with dissolved air. The relatively high N2/O2 ratio in some groundwater compared to the air saturated water suggests an O2 consumption during gas-water-rock interactions occurring at depth. Spatial distribution maps show anomalous concentration of 222Rn CH4, H2 and CO2 dissolved in groundwater at the westernmost area of Las Ca馻das aquifer, which is in good spatial correlation with geophysical and geochemical anomalies related to 2004-2005 seismic-volcanic unrest at Tenerife Island. Determinations of ?13C values in the total dissolved inorganic carbon (TDIC) in groundwater in Las Ca馻das aquifer ranging from -5 to +5 ( vs PDB). This result was explained by isotopic fractionation of either volcanic-hydrothermal CO2 partially dissolved in groundwater or due to precipitation of CaCO3 and CO2 degassing related to silicate hydrolysis dissolving Ca2+.

An Aerial Radiological Survey of Selected Areas of the City of North Las Vegas  

SciTech Connect

As part of the proficiency training for the Radiological Mapping mission of the Aerial Measuring System (AMS), a survey team from the Remote Sensing Laboratory-Nellis (RSL-Nellis) conducted an aerial radiological survey of selected areas of the city of North Las Vegas for the purpose of mapping natural radiation background and locating any man-made radioactive sources. Survey areas were selected in collaboration with the City Manager's office and included four separate areas: (1) Las Vegas Motor Speedway (10.6 square miles); (2) North Las Vegas Downtown Area (9.2 square miles); (3) I-15 Industrial Corridor (7.4 square miles); and (4) Future site of University of Nevada Las Vegas campus (17.4 square miles). The survey was conducted in three phases: Phase 1 on December 11-12, 2007 (Areas 1 and 2), Phase 2 on February 28, 2008 (Area 3), and Phase 3 on March 19, 2008 (Area 4). The total completed survey covered a total of 44.6 square miles. The flight lines (without the turns) over the surveyed areas are presented in Figures 1, 2, 3, and 4. A total of eight 2.5-hour-long flights were performed at an altitude of 150 ft above ground level (AGL) with 300 feet of flight-line spacing. Water line and test line flights were conducted over the Lake Mead and Government Wash areas to ensure quality control of the data. The data were collected by the AMS data acquisition system (REDAR V) using an array of twelve 2-inch x 4-inch x 16-inch sodium iodide (NaI) detectors flown on-board a twin-engine Bell 412 helicopter. Data, in the form of gamma energy spectra, were collected continually (every second) over the course of the survey and were geo-referenced using a differential Global Positioning System. Collection of spectral data allows the system to distinguish between ordinary fluctuations in natural background radiation levels and the signature produced by man-made radioisotopes. Spectral data can also be used to identify specific radioactive isotopes. As a courtesy service, with the approval of the U.S. Department of Energy, National Nuclear Security Administration, Nevada Site Office, RSL-Nellis is providing this summary to the office of the Mayor of the City of North Las Vegas along with the gross-count-based exposure rate and man-made count contour maps and GIS shape files in electronic format on a compact disk.

Shear Velocity Structure Beneath the Las Vegas Valley, Nevada From Regional and Teleseismic Events  

NASA Astrophysics Data System (ADS)

The Las Vegas Valley (LVV), Nevada is located in the central Basin and Range province of western North America. The Valley sits atop a broad sedimentary basin and is susceptible to large earthquakes generated by local and regional faults. During ground motion events, the Las Vegas basin has been found to amplify seismic energy. In addition, the crustal and upper mantle structure of the Valley is poorly understood. Therefore, surface wave data have been used to create shear velocity profiles of the crust and upper mantle beneath LVV using regional and teleseismic events. This project is part of a larger collaborative study, which is characterizing the Las Vegas basin for test site readiness and seismic hazards. Although the frequency of large events is small, the risk associated with such an event is very high for the Valley. As a result, the Las Vegas Valley Broadband array (LVVBB) was deployed in late September 2002 by Lawrence Livermore National Laboratory and the University of Nevada Las Vegas. It consists of a mixture of twelve three-component broadband and short period seismometers deployed in a saw-tooth geometry oriented northeast-southwest across the northeastern and central LVV, above the area estimated to be the deepest portion of the basin. Data examined as part of this study include both regional and global earthquake events recorded within a five-month period on seven of the twelve stations. All seven broadband stations used a three-component Guralp CMG40T sensor with a 40 samples/second sampling rate. Group velocity dispersion curves from Rayleigh waves and Love waves were determined using a multiple filter technique. Rayleigh wave group velocities range from 2.7 to 3.5 km/s for periods from 10 to 30s. Love wave group velocities range from 3.1 to 4.0 km/s for periods from 10 to 100s. In addition, Rg and Lg were examined from local events. 1-D shear velocity profiles of the crust and upper mantle have been produced through inversion along regional source-receiver paths and two-station paths. Shear velocities at depths of 3-5 km have never been directly determined in the Valley; these values will be used to better understand the seismic hazards in the area as well as the tectonic development of southern Nevada in the Basin and Range province.

Final Report for the Arroyo Las Positas Maintenance Impact Study, Lawrence Livermore National Laboratory  

SciTech Connect

In 2000, the Lawrence Livermore National Laboratory's (LLNL) Environmental Protection Department, in coordination with Plant Engineering (PE), began dredging sections of the Arroyo Las Positas (ALP) to alleviate concerns about flooding of sensitive facilities within the mainsite of Lawrence Livermore National Laboratory. In order to reduce potential impacts on the federally threatened California red-legged frog (Rana aurora draytonii), LLNL proposed to dredge sections of the ALP in a ''checkerboard pattern'', resulting in a mosaic of open water habitat and vegetated sections (Figure 1). The Arroyo Las Positas Management Plan (Plan) was coordinated with both state and federal agencies including the U.S. Fish and Wildlife Service (USFWS), California Department of Fish and Game (CDF&G), San Francisco Regional Water Quality Control Board (SFRWQCB), and the Army Corp of Engineers (ACOE). Water Discharge Requirements (WDRs) were issued for this project on December 30, 1999 (Order No. 99-086) by the SFRWQCB. Provision 19 of the WDRs outlined a five-year (2000 through 2004) Maintenance Impact Study (MIS) that LLNL began in coordination with dredging work that was conducted as part of the Arroyo Las Positas Management Plan. Provision 20 of these WDRs requires LLNL to submit a final report of the results of the Maintenance Impact Study for this project to the SFRWQCB. The purpose of this report is to present the results of the Maintenance Impact Study for Arroyo Las Positas and meet the requirements of Provision 20. A description of the annual monitoring included in this Maintenance Impact Study is included in the methods section of this report. Initially the Plan called for dredging the entire length of the Arroyo Las Positas (approximately 6,981 linear feet) over a 5-year period to minimize temporal impacts on the California red-legged frog. Dredging occurred in 2000 ({approx}1,300 ft.), 2001 ({approx}800 ft.), and 2002 ({approx}1,200 ft.), which constituted approximately 3,300 ft., or roughly half of the entire Plan (Figure 2). Logistical challenges and unanticipated cost influenced the decision to terminate the project prior to completion, and re-evaluate the long-term management goals for the ALP. No dredging was conducted in the final two years of the plan (2003 and 2004).

As proficiency training for the Radiological Mapping mission of the Aerial Measuring System (AMS), a survey team from the Remote Sensing Laboratory朜ellis (RSL-Nellis) conducted an aerial radiological survey of the Las Vegas Strip and adjacent areas on December 29, 2008. This survey was one of the bi-annual surveys carried in support of the city of Las Vegas Police Department (LVPD) before significant events on the Las Vegas Strip: e.g., the annual New Year抯 Eve and July Fourth celebrations. The AMS operation and appropriate law enforcement agencies selected this area as an appropriate urban location to exercise AMS capability for mapping environmental radiation and searching for man-made radioactive sources. The surveys covered approximately 11 square miles. Each survey required a 2.5-hour-long flight, performed at an altitude of 300 ft above ground level (AGL) at a line spacing of 600 ft. Water line and test line flights are conducted over the Lake Mead and Government Wash areas to determine the non-terrestrial background contributed by aircraft, radon, and cosmic activity, and to determine the altitude-dependent air mass correction. The data were collected by the AMS data acquisition system (REDAR V) using an array of twelve 2" x 4" x 16" sodium iodide (NaI) detectors flown on-board a twin-engine Bell 412 helicopter. Gamma energy spectral data were collected second-by-second over the survey area. This spectral data allows the system to distinguish between natural terrestrial background contributions and man-made radioisotope contributions. Spectral data can also be used to identify specific man-made radioactive isotopes. Data geo-locations were determined with a Real-Time Differential Global Positioning System (RDGPS).

The survey route passes immediately south of the potential site for a high-level nuclear waste repository at Yucca Mountain in southern Nevada. Comparisons among the results of the several repeated levelings along this survey route provide a partial basis for evaluating contemporary crustal deformation patterns in the vicinity of the Yucca Mountain site and the relation between any such deformation and geologic structures known or suspected to have been active during Quaternary time.

Machines, medication, modulation: circuits of dependency and self-care in Las Vegas.  

PubMed

The intensive entertainment infrastructure of Las Vegas is overlaid with a robust therapeutic network for those who become addicted to its technologies. Although the objectives of gambling machines and addiction therapeutics are seemingly at odds--the first work to encourage play, the second to stop it--both gear their interventions around a model of the self as a continuum of behavioral potentials that can be externally modulated. For compulsive gamblers implicated in this circuit of modulation, pharmaceutical drugs that have been prescribed to dampen cravings for machine play sometimes function as intensifiers of its effects. Caught in an intractable play between technologies of harm and technologies of care, recovering gambling addicts are challenged to assemble a technical array through which they can maintain balance; health itself, for these individuals, becomes a state of managed dependency. This essay explores the shifting terms and changing stakes of subjectivity and health in the contemporary United States by way of ethnographic research on compulsive gamblers who live and work in Las Vegas. The analysis draws on interviews with gamblers as well as on observations in local self-help groups, directed group therapy sessions, and chat rooms of Internet recovery Web sites. PMID:16944328

[Vectorial and congenital transmission of Trypanosoma cruzi in Las Lomitas, Formosa].  

PubMed

Chagas disease, caused by Trypanosoma cruzi, is a major cause of morbidity and mortality in Latin America. The objective of this study was to describe the rate of infestation in four aboriginal communities in Las Lomitas (Great Chaco Region), Formosa, Argentina; the rate of infection in children residing in these communities, in blood donors and in pregnant women who received care at the Hospital Las Lomitas, as well as the rate of congenital infection in children born to women infected during the study period. The rate of infestation of 172 households evaluated in 2006 reached 32%. Prevalence of infection among 445 people was 17.5% and in children under 5 years old it was 8.6%. The rate of infection reached 18.6% in blood donors and 29.1% in pregnant women. The rate of infection among 47 children born to infected women, and living in residences under vectorial surveillance was 17.0%. These infections were considered as congenital. This study showed indexes compatible with active vectorial transmission at the beginning. After vectorial control with insecticides the infestation rate has been reduced to 3.3%. The local health system has introduced high impact procedures of primary and secondary prevention in order to prevent new cases and to treat infected people. PMID:19770096

Phlebotominae spatial distribution asssociated with a focus of tegumentary leishmaniasis in Las Lomitas, Formosa, Argentina, 2002.  

PubMed

Las Lomitas, Formosa, Argentina, reported 96 cases of tegumentary leishmaniasis during 2002. The urban transmission was suggested although previous outbreaks were related with floods of the Bermejo river (BR) 50 km from the village. Phlebotomine collections were performed during March 2002 to define the spatial distribution of risk, together with satellite imaginery. The phlebotomine/trap obtained was 1679.5 in the southern BR shore, 1.1 in the periruban-rural environment and 2.3 in the northern Pilcomayo river marshes. Lutzomyia neivai was the prevalent species (91.1%) among the 2393 phlebotomine captured, and it was only found in the BR traps. The other species were L. migonei (7.9%), L. cortelezzii (0.9%), and Brumptomyia guimaraesi (0.1%). The satellite images analysis indicates that the fishing spots at the BR were significantly overflowed during the transmission peak, consistent with fishermen recollections. This spatial restricted flood might concentrate vectors, reservoirs, and humans in high places. Therefore, both the spatial distribution of vectors and the sensor remoting data suggests that in Las Lomitas area the higher transmission risk it is still related with the gallery forest of the BR, despite of the urban residence of the cases. The surveillance and control implications of these results are discussed. PMID:16862326
