    An incursion of classical swine fever virus (CSFV) into the domestic pig population in South Africa, identified in 2005, raised the concern that infection might spread to wildlife species and be maintained in these hosts. This study sought to determine whether two wildlife Suidae species present in South Africa, the bushpig (Potamochoerus larvatus) and the common warthog (Phacochoerus africanus), could support productive CSFV infection. Both species could be infected with CSFV and transmitted infection to in-contact animals of the same species. Viral antigen and RNA genome were detected in blood/serum and animals that survived initial infection seroconverted approximately 10-14 days post-inoculation. Viral RNA remained detectable in nasal and saliva secretions for prolonged periods until monitoring ended at 42-44 days after initial challenge. These data suggest that both Suidae species could serve to spread circulating CSFV within wild populations, with implications for disease control. PMID:21294855

    A 14-yr-old male African warthog (Phacochoerus aethiopicus) with a chronic history of intermittent unilateral epistaxis, degenerative osteoarthritis, and intermittent weakness in the distal lumbar trunk was evaluated to determine the source of epistaxis. No obvious cause was determined, and in light of severe osteoarthritis and a holosystolic cardiac murmur, the animal was euthanized. A tumor of the right adrenal gland involving the medulla was found at gross necropsy. Immunohistochemical staining of the tumor was positive for chromogranin and negative for neurofilament protein, which was diagnostic for pheochromocytoma. No lesions were observed in either nasal cavity. Systolic, diastolic, and mean arterial pressures measured at the time of immobilization were elevated when compared with another African warthog immobilized with a similar anesthetic regimen. Additionally, the warthog had pronounced serum norepinephrine dominance with a norepinephrine:epinephrine ratio of 10.0, compared with 0.36 from clinically normal warthogs. Practitioners should consider pheochromocytoma when evaluating warthogs or swine for epistaxis. PMID:19110715

    Wild African Suidae, the common warthog (Phacochoerus africanus) and bushpig (Potamochoerus larvatus), were experimentally infected with classical swine fever (CSF) virus following the diagnosis of CSF subtype 2.1 in domestic pigs in South Africa in 2005. No data regarding the susceptibility or potential lesions of these African wild suids are available. Seven subadult warthogs and six bushpigs were captured and infected intranasally with the South African isolate. Two in-contact control animals of the same species in each experiment verified intra-species transmission. Surviving animals were euthanized after 44?days. Formalin-fixed tissue samples collected from them as well as animals euthanized during the trial were evaluated for histological lesions. The warthogs, which were clinically normal throughout the study, developed histological lesions that were inconsistently present and sometimes subtle. Three individuals, including one in-contact control, developed distinct lympho-plasmacytic cuffing in their brains. Subtle lesions included scant lympho-plasmacytic infiltration of various organs, occasionally accompanied by perivascular cuffing. In contrast, the bushpigs developed overt clinical signs similar to CSF in domestic pigs. Four of six animals, including two in-contact controls, died or were euthanized during the trial. On postmortem examination, intestinal necrosis and ulceration, purulent rhinitis and pneumonia were present. Affected animals developed lymphoid necrosis and depletion whilst surviving individuals showed perivascular cuffing in multiple organs. From the present work, we conclude that these wild Suidae are susceptible to CSF virus and intra-species transmission under experimental conditions can occur. PMID:21176120

    Global climate fluctuated considerably throughout the Pliocene and Pleistocene, influencing the evolutionary history of a wide range of species. Using both mitochondrial sequences and microsatellites, we have investigated the evolutionary consequences of such environmental fluctuation for the patterns of genetic variation in the common warthog, sampled from 24 localities in Africa. In the sample of 181 individuals, 70 mitochondrial DNA haplotypes were identified and an overall nucleotide diversity of 4.0% was observed. The haplotypes cluster in three well-differentiated clades (estimated net sequence divergence of 3.1-6.6%) corresponding to the geographical origins of individuals (i.e. eastern, western and southern African clades). At the microsatellite loci, high polymorphism was observed both in the number of alleles per locus (6-21), and in the gene diversity (in each population 0.59-0.80). Analysis of population differentiation indicates greater subdivision at the mitochondrial loci (FST=0.85) than at nuclear loci (FST=0.20), but both mitochondrial and nuclear loci support the existence of the three warthog lineages. We interpret our results in terms of the large-scale climatic fluctuations of the Pleistocene. PMID:14512951

    The prevalence of trypanosome infections in warthogs (Phacochoerus aethiopicus) in The Gambia was found to be 11% of a sample of 62 animals. All isolates were identified as Trypanosoma simiae. Serological evidence indicated a higher level of exposure to T. simiae, but results were inconclusive for the presence of Trypanosoma congolense. The course of T. simiae infection in warthog piglets showed a rapidly rising parasitaemia, with a concomitant fall in packed cell volume, and resulted in a prolonged period of low-level parasitaemia. The same infections killed domestic piglets. PMID:1502780

    The objectives of this study were to analyse faecal steroid metabolites in African and South East Asian pig species kept in European zoos. Species studied were the warthog (Phacochoerus africanus), the red river hog (Potamochoerus porcus) and the babirusa (Babyrousa babyrussa). Faecal samples were collected 1-3 times per week from non-pregnant and pregnant captive female warthogs (n = 9), red river hogs (n = 7) and babirusas (n = 5). Enzyme-immunoassays for faecal progesterone, androgen, and oestrogen metabolites, were tested for their ability to determine follicular and luteal phases. In all three species, oestrous cycles could be monitored with 20alpha-OH- and 20-oxo-pregnane assays. In contrast, oestrogens and androgens were not useful in characterising follicular activity during the oestrous cycle in any species. Faecal 20alpha-OH- and 20-oxo-pregnane values were significantly correlated. Faecal pregnane concentrations revealed species-specific differences. Luteal phase values of 20alpha-OH-pregnanes were considerably higher than 20-oxo-pregnanes; 20alpha-OH-pregnanes were in the range of 3-10 microg/g in warthogs and red river hogs, whereas concentrations were 30-200 microg/g faeces in the babirusa. Regular oestrus cycles had a length of about 35 days in all three species studied. Results indicated a seasonal influence on the occurrence of reproductive cycles in the warthog with anoestrous periods in the European summer. The red river hog was found to be a seasonal and poly oestrous breeder; oestrus cycles started by January and continued until summer. In contrast, the babirusa showed non-seasonal ovarian cyclicity. In pregnant red river hogs, progesterone metabolites were comparable to luteal phase values of the oestrous cycle during the first 3 months of gestation, but did further increase during the last month of pregnancy. Oestrogens and 17-oxo-androstanes were significantly elevated during the second half of gestation. In summary, the reproductive biology of three exotic pig species was studied using non-invasive faecal steroid analysis and these methods were used for comparative investigations of oestrous cycles, pregnancy and seasonality.

    Periodontal lesions were found in 14 of 100 bushpig (Potamochoerus porcus) skulls and nine of 103 warthog (Phacochoerus aethiopicus) skulls from southern Africa. The prevalence of periodontal disease showed a significant increase with age in the bushpig but not in the warthog skulls. All the lesions affected the cheek teeth, particularly the molars. The lower prevalence of lesions in older warthogs may be associated with their specialised molars and abrasive diet. PMID:2915404

    Concentrations of sodium, potassium, chloride, inorganic phosphorus, total calcium, total magnesium, albumin, total protein, cholesterol, urea, creatinine, cortisol as well as the activities of alkaline phosphatase, alanine transaminase, aspartate transaminase, gamma-glutamyltransferase, creatine kinase and lactate dehydrogenase were determined in serum specimens collected from 100 free-ranging warthogs Phacochoerus aethiopicus within five minutes after they were killed with a shotgun. Average concentrations for the following chemical constituents were found: sodium (145 mmol l-1), potassium (8.6 mmol l-1), chloride (102.5 mmol l-1), phosphorus (2.31 mmol l-1), calcium (2.93 mmol l-1), magnesium (1.23 mmol l-1), albumin (26.4 g l-1), serum proteins (62.2 g l-1), cholesterol (1.82 mmol l-1) and urea (8.74 mmol l-1). The cortisol concentrations ranged from 55-340 nmol l-1 (n = 30). Wide variations were recorded in the concentration of creatinine as well as in the activities of the various enzymes. PMID:3508207

    A 38-day-old male warthog (Phacochoerus aethiopicus) with marked anaemia (haematocrit = 14 %) presented to the Denver Zoological Gardens hospital with ataxia, tachypnoea, suspected stunted growth and cardiomegaly. The piglet demonstrated some features consistent with both iron deficiency anaemia and autoimmune haemolytic anaemia. Serum-soluble iron was below the level of detection (< 8.96 micromol/l). Iron deficiency anaemia is a well recognised entity in domestic swine reared on concrete and denied access to soil. Fifteen captive warthogs were subsequently evaluated for serum soluble iron content (mean = 21.62 +/- 4.36 micromol/l as well as 5 neonatal warthog piglets that required hand-rearing. Only 1 of 5 neonatal warthog piglets had measurable serum soluble iron (9.50 micromol/l). These data suggest that warthogs are similar to domestic swine and are born with low iron stores. Some form of iron supplementation should be considered for captive neonatal warthog piglets, especially if they are reared on concrete. PMID:12515305

    Vascular myelopathies of the spinal cord have not been described in Suidae, and are a rare finding in companion animals. An 8.5-yr female African warthog (Phacochoerus africanus) presented with an acute onset of tetraparesis. Based on neurologic findings, a cervical spinal cord lesion between C7-T2 was suspected. Magnetic resonance imaging revealed severe intramedullary hemorrhage with suspected abnormal vessels in the spinal cord at the level of the seventh cervical vertebrae. The acute onset of clinical signs and rapid deterioration of neurological status precluded surgical managements. A vascular anomaly was suspected on gross pathology and histology. Immunohistochemistry identified the lesion as a spontaneous intramedullary hematoma. Spontaneous intramedullary hematomyelia should be considered as a differential for acute onset of paresis in suid species. PMID:17319141

    A total of 38 warthog, Phacochoerus aethiopicus, shot on a farm in northern South West Africa/Namibia were examined for internal and external parasites at monthly intervals over a period of 13 months. They harboured cestodes, 9 nematode species, 6 ixodid tick species and 1 species each of an argasid tick, a flea, a louse and larvae of a dipteran fly. Clear patterns of seasonal abundance could be determined only for the spirurid stomach worm, Physocephalus sexalatus, and the sucking louse, Haematopinus phachoeri. PMID:6634088

    Oesophagostomum mocambiquei Ortlepp, 1964 was described from 9 females recovered from a warthog, Phacochoerus aethiopicus (Pallas, 1766), from northern Mozambique. Large numbers of O. mocambiquei were recovered during subsequent surveys of the parasites of warthogs from the Kruger National Park and the Hoedspruit Nature Reserve. The males, which have not yet been described, resemble those of Oesophagostomum santosdiasi Ortlepp, 1964 in the principal measurements. They can, however, be differentiated by the shape of the mouth capsule, which is round in O. mocambiquei and oval in O. santosdiasi. A simplified key for the identification of the Oesophagostomum species that occur in warthogs in South Africa and Namibia is provided and the differences between them tabulated. The names Oesophagostomum moçambiquei and Oesophagostomum santos-diasi are corrected to O. mocambiquei and O. santosdiasi respectively, since diacritic marks are not allowed under the Code of International Zoological Nomenclature.

    Sarcocystis dubeyella n. sp. and S. phacochoeri n. sp. from muscle fibers of the skeletal musculature of two warthogs in South Africa are described by light and and electron microscopy. Sarcocystis dubeyella sarcocysts are macroscopic (up to 12 mm long and 1 mm wide), with a parasite-induced encapsulation of the host muscle fiber in which the plasma membrane of the latter remained unaltered. The sarcocyst wall is characterized by evenly arranged, irregularly semicircular or rectangular villar protrusions (5.0 x 2.8-11.0 microns) with indented margins and no specific content. Sarcocystis phacochoeri formed filiform microcysts (up to 4 mm long and 0.13 mm wide). Its cyst wall is provided with tightly packed, molarlike villar protrusions (1.6-3.3 x 1.7-3.3 microns), with smooth margins, hollow on one side, and with longitudinal condensations of the fine granular matrix at various locations in the interior.

    1999-08-23

    The warthog (wrt) gene, recovered as a modifier for Notch signaling, was found to encode the Drosophila homologue of rab6, Drab6. Vertebrate and yeast homologues of this protein have been shown to regulate Golgi network to TGN trafficking. To study the function of this protein in the development of a multicellular organism, we analyzed three different warthog mutants. The first was an R62C point mutation, the second a genomic null, and the third was an engineered GTP-bound form. Our studies show, contrary to yeast, that the Drosophila homologue of rab6 is an essential gene. However, it has limited effects on development beyond the larval stage. Only the mechanosensory bristles on the head, notum, and scutellum are affected by warthog mutations. We present models for the modifying effect of Drab6 on Notch signaling. PMID:10459009

    Although there were no obvious signs of illness following experimental infection of young warthog with African swine fever virus, the animals developed viraemias between 10(2,4) and 10(3,6) HD50/ml within the first week of infection, and virus concentrations in a number of lymphatic tissues attained high levels (greater than or equal to 10(6) HD50/g). Unlike in blood, and to some extent in the spleen, virus titres in lymph nodes did not decline appreciable during the 33-day observation period, since at the end of the period lymphatic tissues from 2 warthog were still infectious for domestic pigs to which these tissues were fed.

    1988-12-01

    The genomes of African swine fever virus isolates collected from soft ticks (Ornithodoros moubata) inhabiting warthog burrows in four areas of Zambia were compared by restriction enzyme site mapping. Isolates from different areas showed considerable diversity. The regions of genomes that differed between isolates were distributed throughout the virus genome, although some more conserved regions were identified, such as the right-hand third of the genome. The genomes of seven isolates from neighbouring warthog burrows within Livingstone Game Park in southern Zambia were more similar to each other than those from different areas. However, a number of differences were observed even between the genomes of isolates from the same warthog burrow. The variation between these latter isolates probably resulted from point mutations located at various positions along the genome, in addition to small additions or deletions at both terminal regions. Restriction enzyme site mapping indicated that one isolate may have originated by earlier recombination between two distinguishable viruses. PMID:3199101

    The role of the ancestral sylvatic cycle of the African swine fever virus (ASFV) is not well understood in the endemic areas of eastern Africa. We therefore analysed the ASF infection status on samples collected from 51 free-ranging warthogs (Phacocherus africanus) and 1576 Ornithodorus porcinus ticks from 26 independent warthog burrows at a single ranch in Kenya. Abattoir samples from 83 domestic pigs without clinical symptoms, originating from specific locations with no recent reported ASF outbreaks were included in this study. All samples were derived from areas of central Kenya, where ASF outbreaks have been reported in the past. Infection with ASFV was confirmed in 22?% of O. porcinus pools, 3.22?% of adult warthog serum samples and 49?% of domestic pig serum samples by using p72-based PCR. All of the warthog sera were positive for anti-ASFV antibodies, investigated by using ELISA, but none of the domestic pig sera were positive. Twenty O. porcinus-, 12 domestic pig- and three warthog-derived viruses were genotyped at four polymorphic loci. The ASFV isolates from ticks and domestic pigs clustered within p72 genotype X. By contrast, ASF viruses genotyped directly from warthog sera, at same locality as the tick isolates, were within p72 genotype IX and genetically similar to viruses causing recent ASF outbreaks in Kenya and Uganda. This represents the first report of the co-existence of different ASFV genotypes in warthog burrow-associated ticks and adult wild warthogs. The data from this and earlier studies suggest transfer of viruses of at least two different p72 genotypes, from wild to domestic pigs in East Africa. PMID:20965989

  1. Artificial Warthog Burrows Used to Sample Adult and Immature Tsetse (Glossina spp) in the Zambezi Valley of Zimbabwe

    Background The biology of adult tsetse (Glossina spp), vectors of trypanosomiasis in Africa, has been extensively studied – but little is known about larviposition in the field. Methodology/Principal Findings In September-November 1998, in the hot-dry season in Zimbabwe’s Zambezi Valley, we used artificial warthog burrows to capture adult females as they deposited larvae. Females were subjected to ovarian dissection and were defined as perinatal flies, assumed to have entered burrows to larviposit, if oocyte sizes indicated >95% pregnancy completion. Perinatal flies were defined as full-term pregnant if there was a late third instar larva in utero, or postpartum if the uterus was empty. All other females were defined as pre-full-term pregnant (pre-FT). Of 845 G. m. morsitans captured, 91% (765) were female and 295/724 (41%) of females dissected were perinatal flies. By contrast, of 2805 G. pallidipes captured only 71% (2003) were female and only 33% (596/1825) of females were perinatal. Among all perinatal females 67% (596/891) were G. pallidipes. Conversely, in burrows not fitted with traps – such that flies were free to come and go – 1834 (59%) of pupae deposited were G. m. morsitans and only 1297 (41%) were G. pallidipes. Thus, while more full-term pregnant G. pallidipes enter burrows, greater proportions of G. m. morsitans larviposit in them, reflecting a greater discrimination among G. pallidipes in choosing larviposition sites. Catches of males and pre-FT females increased strongly with temperatures above 32°C, indicating that these flies used burrows as refuges from high ambient temperatures. Conversely, catches of perinatal females changed little with maximum temperature but declined from late September through November: females may anticipate that burrows will be inundated during the forthcoming wet season. Ovarian age distributions of perinatal and pre-FT females were similar, consistent with all ages of females larvipositing in burrows with similar probability. Conclusions/Significance Artificial warthog burrows provide a novel method for collecting tsetse pupae, studying tsetse behaviour at larviposition, assessing the physiological status of female tsetse and their larvae, and of improving understanding of the physiological dynamics of terminal pregnancy, and population dynamics generally, with a view to improving methods of trypanosomiasis control.

    Five novel herpesviruses were identified in suid species from Africa (common warthog, Phacochoerus africanus) and South-East Asia (bearded pig, Sus barbatus; babirusa, Babyrousa babyrussa) by detection and analysis of their DNA polymerase genes. Three of the novel species, P. africanus cytomegalovirus 1, P. africanus lymphotropic herpesvirus 1 (PafrLHV-1) and S. barbatus lymphotropic herpesvirus 1 (SbarLHV-1), were closely related to known beta- (porcine cytomegalovirus) and gammaherpesviruses [porcine lymphotropic herpesvirus (PLHV) 1 and 3] of domestic pigs. In contrast, two novel species, S. barbatus rhadinovirus 1 (SbarRHV-1) and Babyrousa babyrussa rhadinovirus 1 (BbabRHV-1), were more closely related to a ruminant gammaherpesvirus, bovine herpesvirus 4 (BoHV-4), than to the porcine gammaherpesviruses PLHV-1, -2, -3, PafrLHV-1 and SbarLHV-1. SbarRHV-1, BbabRHV-1 and BoHV-4 were therefore tentatively assigned to a novel genogroup of artiodactyl gammaherpesviruses. This latter genogroup may also contain an as yet undiscovered gammaherpesvirus of domestic pigs, thereby adding a concern to their use in xenotransplantation. PMID:15039528

    1982-08-01

    The results of post-mortem examinations of 90 warthog (Phacochoerus aethiopicus) conducted in the Ruwenzori National Park, Uganda during a survey of tuberculous infection in wildlife are described. Nine per cent of warthog were found to show gross lesions on autopsy and of these organisms which could by typed, Mycobacterium bovis was isolated in 2 of 6 cases and 5 atypical mycobacterial strains were isolated from the remaining 4. The distribution and character of the lesions is described and it is concluded that the route of infection in the warthog is alimentary. A mycobacterial survey of 8 other species of mammals, 7 species of birds, 5 species of fish and 1 species of amphibian is described. None of the mammals (except possibly 1 elephant), birds, fish or amphibia is described. None of the mammals (except possibly 1 elephant), birds, fish or amphibia was found to be infected with M. bovis but several individuals were found to harbour atypical, probably saprophytic, mycobacterial types. The origin of tuberculosis in buffalo and warthog in the Ruwenzori National Park is discussed and is concluded to have been previous contact with domestic cattle. PMID:7123664

    Veterinary cordon fences are used in Southern Africa to separate wildlife from domestic animals in order to prevent transmission of infectious diseases. Such fences are a control method recognized by the World Organization for Animal Health (OIE) for establishing disease-free zones in beef exporting countries. However, few studies have evaluated the ecological impact of these physical barriers or their effectiveness at a multispecies level. We examined the permeability of one such barrier, along 357 km of the western and southern boundary of the Kruger National Park (KNP) during 2007. Information was gathered using a semi-structured questionnaire implemented among 32 teams of fence maintenance workers. Data were analyzed to identify (a) the main causes of fence damage, (b) the seasonality, location and duration of fence repairs, (c) high permeability areas for elephant (Loxodonta africana), kudu (Tragelaphus strepsiceros), impala (Aepyceros melampus), buffalo (Syncerus caffer) and warthog (Phacochoerus africanus), and (d) the influence of fence electrification, rivers and elephant damage on the frequency of observation of wildlife species outside the KNP estimated during the year. Human and elephant damage were the most common reasons for fence repairs. Elephant and buffalo were the most and least common large mammal species reported observed outside the KNP (1076 and 162 reports/year), respectively. Cattle incursions into the KNP were also reported in 44% of the fence sections. Electrification of the fence was an important factor explaining differences in estimated wildlife species observations outside the KNP during the year. Correlations between estimations of observed species suggested that fence gaps created by elephants might be used by the other wildlife species. Estimated annual counts of kudu, impala and buffalo, but not warthog, were found to correlate with elephant observations. Negative binomial regression models were developed to explore the relationships between observed estimations of different wildlife species outside the KNP the fence, electrification of fence sections and the presence of watercourses, suggesting that kudu, impala and buffalo could use elephant induced fence damage to leave the KNP. The questionnaire was able to evaluate fence integrity and identify sections where integrity was sub-optimal for separating wildlife from domestic livestock species. If combined with more quantitative methods and applied on a routine basis, it could provide an efficient and cost-effective method for monitoring the effectiveness of physical barriers to contain wildlife within protected areas such as is the case with veterinary cordon fences in Southern Africa.

    Common knowledge of intentions is crucial to basic social tasks ranging from cooperative hunting to oligopoly collusion, riots, revolutions, and the evolution of social norms and human culture. Yet little is known about how common knowledge leaves a trace on the dynamics of a social network. Here we show how an individual's network properties---primarily local clustering and betweenness centrality---provide strong signals of the ability to successfully participate in common knowledge tasks. These signals are distinct from those expected when practices are contagious, or when people use less-sophisticated heuristics that do not yield true coordination. This makes it possible to infer decision rules from observation. We also find that tasks that require common knowledge can yield significant inequalities in success, in contrast to the relative equality that results when practices spread by contagion alone.

    High technology industries with high failure costs commonly use redundancy as a means to reduce risk. Redundant systems, whether similar or dissimilar, are susceptible to Common Cause Failures (CCF). CCF is not always considered in the design effort and, therefore, can be a major threat to success. There are several aspects to CCF which must be understood to perform an analysis which will find hidden issues that may negate redundancy. This paper will provide definition, types, a list of possible causes and some examples of CCF. Requirements and designs from NASA projects will be used in the paper as examples.

    This study was conducted on the basis of a modification to Contract NAS8-36413, Space Station Commonality Analysis, which was initiated in December, 1987 and completed in July, 1988. The objective was to investigate the commonality aspects of subsystems and mission support hardware while technology experiments are accommodated on board the Space Station in the mid-to-late 1990s. Two types of mission are considered: (1) Advanced solar arrays and their storage; and (2) Satellite servicing. The point of departure for definition of the technology development missions was a set of missions described in the Space Station Mission Requirements Data Base. (MRDB): TDMX 2151 Solar Array/Energy Storage Technology; TDMX 2561 Satellite Servicing and Refurbishment; TDMX 2562 Satellite Maintenance and Repair; TDMX 2563 Materials Resupply (to a free-flyer materials processing platform); TDMX 2564 Coatings Maintenance Technology; and TDMX 2565 Thermal Interface Technology. Issues to be addressed according to the Statement of Work included modularity of programs, data base analysis interactions, user interfaces, and commonality. The study was to consider State-of-the-art advances through the 1990s and to select an appropriate scale for the technology experiments, considering hardware commonality, user interfaces, and mission support requirements. The study was to develop evolutionary plans for the technology advancement missions.

    Pain in infancy and childhood is extremely common. Sources of pain include illness, injury, and medical and dental procedures. Over the past two decades, tremendous progress has been made in the assessment, prevention and treatment of pain. It is important for the paediatric health care provider to be aware of the implications and consequences of pain in childhood. A multitude of interventions are available to reduce or alleviate pain in children of all ages, including neonates. These include behavioural and psychological methods, as well as a host of pharmacological preparations, which are safe and effective when used as indicated. Many complementary and alternative treatments appear to be promising in treating and relieving pain, although further research is required. The present article reviews the most common sources of pain in childhood and infancy, as well as current treatment strategies and options. PMID:19030348

    In this paper, I discuss a "misconception" in magnetism so simple and pervasive as to be typically unnoticed. That magnets have poles might be considered one of the more straightforward notions in introductory physics. However, the magnets common to students' experiences are likely different from those presented in educational contexts. This leads students, in my experience, to frequently and erroneously attribute magnetic poles based on geometric associations rather than actual observed behavior. This polarity discrepancy can provide teachers the opportunity to engage students in authentic inquiry about objects in their daily experiences. I've found that investigation of the magnetic polarities of common magnets provides a productive context for students in which to develop valuable and authentic scientific inquiry practices.

    2015-01-01

    Common Cause Failures (CCFs) are a known and documented phenomenon that defeats system redundancy. CCFS are a set of dependent type of failures that can be caused by: system environments; manufacturing; transportation; storage; maintenance; and assembly, as examples. Since there are many factors that contribute to CCFs, the effects can be reduced, but they are difficult to eliminate entirely. Furthermore, failure databases sometimes fail to differentiate between independent and CCF (dependent) failure and data is limited, especially for launch vehicles. The Probabilistic Risk Assessment (PRA) of NASA's Safety and Mission Assurance Directorate at Marshall Space Flight Center (MFSC) is using generic data from the Nuclear Regulatory Commission's database of common cause failures at nuclear power plants to estimate CCF due to the lack of a more appropriate data source. There remains uncertainty in the actual magnitude of the common cause risk estimates for different systems at this stage of the design. Given the limited data about launch vehicle CCF and that launch vehicles are a highly redundant system by design, it is important to make design decisions to account for a range of values for independent and CCFs. When investigating the design of the one-out-of-two component redundant system for launch vehicles, a response surface was constructed to represent the impact of the independent failure rate versus a common cause beta factor effect on a system's failure probability. This presentation will define a CCF and review estimation calculations. It gives a summary of reduction methodologies and a review of examples of historical CCFs. Finally, it presents the response surface and discusses the results of the different CCFs on the reliability of a one-out-of-two system.

    The Common Geometry Module (CGM) is a code library which provides geometry functionality used for mesh generation and other applications. This functionality includes that commonly found in solid modeling engines, like geometry creation, query and modification; CGM also includes capabilities not commonly found in solid modeling engines, like geometry decomposition tools and support for shared material interfaces. CGM is built upon the ACIS solid modeling engine, but also includes geometry capability developed beside and onmore »top of ACIS. CGM can be used as-is to provide geometry functionality for codes needing this capability. However, CGM can also be extended using derived classes in C++, allowing the geometric model to serve as the basis for other applications, for example mesh generation. CGM is supported on Sun Solaris, SGI, HP, IBM, DEC, Linux and Windows NT platforms. CGM also indudes support for loading ACIS models on parallel computers, using MPI-based communication. Future plans for CGM are to port it to different solid modeling engines, including Pro/Engineer or SolidWorks. CGM is being released into the public domain under an LGPL license; the ACIS-based engine is available to ACIS licensees on request.« less

  2. 'Historicising common sense'.

    PubMed

    Millstone, Noah

    2012-12-01

    This essay is an expanded set of comments on the social psychology papers written for the special issue on History and Social Psychology. It considers what social psychology, and particularly the theory of social representations, might offer historians working on similar problems, and what historical methods might offer social psychology. The social history of thinking has been a major theme in twentieth and twenty-first century historical writing, represented most recently by the genre of 'cultural history'. Cultural history and the theory of social representations have common ancestors in early twentieth-century social science. Nevertheless, the two lines of research have developed in different ways and are better seen as complementary than similar. The theory of social representations usefully foregrounds issues, like social division and change over time, that cultural history relegates to the background. But for historians, the theory of social representations seems oddly fixated on comparing the thought styles associated with positivist science and 'common sense'. Using historical analysis, this essay tries to dissect the core opposition 'science : common sense' and argues for a more flexible approach to comparing modes of thought. PMID:23135802

    The COMCAN fault tree analysis codes are designed to analyze complex systems such as nuclear plants for common causes of failure. A common cause event, or common mode failure, is a secondary cause that could contribute to the failure of more than one component and violates the assumption of independence. Analysis of such events is an integral part of system reliability and safety analysis. A significant common cause event is a secondary cause common tomore »all basic events in one or more minimal cut sets. Minimal cut sets containing events from components sharing a common location or a common link are called common cause candidates. Components share a common location if no barrier insulates any one of them from the secondary cause. A common link is a dependency among components which cannot be removed by a physical barrier (e.g.,a common energy source or common maintenance instructions).« less

    Context Clinical experience and factor analytic studies suggest that some psychiatric disorders may be more closely related to one another, as indicated by the frequency of their co-occurrence, which may have etiologic and treatment implications. Objective To construct a virtual space of common psychiatric disorders, spanned by factors reflecting major psychopathologic dimensions, and locate psychiatric disorders in that space, as well as to examine whether the location of disorders at baseline predicts the prevalence and incidence of disorders at 3-year follow-up. Design, Setting, and Patients A total of 34 653 individuals participated in waves 1 and 2 of the National Epidemiologic Survey on Alcohol and Related Conditions. Main Outcome Measures The distance between disorders at wave 1, calculated using the loadings of the factors spanning the space of disorders as coordinates. This distance was correlated with the adjusted odds ratios for age, sex, and race/ethnicity of the prevalence and incidence of Axis I disorders in wave 2, with the aim of determining whether smaller distances between disorders at wave 1 predicts higher disorder prevalence and incidence at wave 2. Results A model with 3 correlated factors provided an excellent fit (Comparative Fit Index = 0.99, Tucker-Lewis Index=0.98, root mean square error of approximation=0.008) for the structure of common psychiatric disorders and was used to span the space of disorders. Distances ranged from 0.070 (between drug abuse and dysthymia) to 1.032 (between drug abuse and avoidant personality disorder). The correlation of distance between disorders in wave 1 with adjusted odds ratios of prevalence in wave 2 was ?0.56. The correlation of distance in wave 1 with adjusted odds ratios of incidence in wave 2 was ?0.57. Conclusions Mapping psychiatric disorders can be used to quantify the distances among disorders. Proximity in turn can be used to predict prospectively the incidence and prevalence of Axis I disorders. PMID:23266570

  6. Common Control System Vulnerability

    SciTech Connect

    Trent Nelson

    2005-12-01

    The Control Systems Security Program and other programs within the Idaho National Laboratory have discovered a vulnerability common to control systems in all sectors that allows an attacker to penetrate most control systems, spoof the operator, and gain full control of targeted system elements. This vulnerability has been identified on several systems that have been evaluated at INL, and in each case a 100% success rate of completing the attack paths that lead to full system compromise was observed. Since these systems are employed in multiple critical infrastructure sectors, this vulnerability is deemed common to control systems in all sectors. Modern control systems architectures can be considered analogous to today's information networks, and as such are usually approached by attackers using a common attack methodology to penetrate deeper and deeper into the network. This approach often is composed of several phases, including gaining access to the control network, reconnaissance, profiling of vulnerabilities, launching attacks, escalating privilege, maintaining access, and obscuring or removing information that indicates that an intruder was on the system. With irrefutable proof that an external attack can lead to a compromise of a computing resource on the organization's business local area network (LAN), access to the control network is usually considered the first phase in the attack plan. Once the attacker gains access to the control network through direct connections and/or the business LAN, the second phase of reconnaissance begins with traffic analysis within the control domain. Thus, the communications between the workstations and the field device controllers can be monitored and evaluated, allowing an attacker to capture, analyze, and evaluate the commands sent among the control equipment. Through manipulation of the communication protocols of control systems (a process generally referred to as ''reverse engineering''), an attacker can then map out the control system processes and functions. With the detailed knowledge of how the control data functions, as well as what computers and devices communicate using this data, the attacker can use a well known Man-in-the-Middle attack to perform malicious operations virtually undetected. The control systems assessment teams have used this method to gather enough information about the system to craft an attack that intercepts and changes the information flow between the end devices (controllers) and the human machine interface (HMI and/or workstation). Using this attack, the cyber assessment team has been able to demonstrate complete manipulation of devices in control systems while simultaneously modifying the data flowing back to the operator's console to give false information of the state of the system (known as ''spoofing''). This is a very effective technique for a control system attack because it allows the attacker to manipulate the system and the operator's situational awareness of the perceived system status. The three main elements of this attack technique are: (1) network reconnaissance and data gathering, (2) reverse engineering, and (3) the Man-in-the-Middle attack. The details of this attack technique and the mitigation techniques are discussed.

  7. Common lung conditions: asthma.

    Delzell, John E

    2013-06-01

    Asthma is a common respiratory disease that leads to school and work absenteeism, office and emergency department visits, hospitalization, and mortality. Dyspnea and wheezing are caused by airway inflammation. Asthma severity scores are used to predict the risk of exacerbations. Severity assessment instruments include questions about daytime and nighttime symptoms, use of short-acting beta2-agonists, and the effect of symptoms on daily activities. The 4 components of effective asthma management are monitoring, education, control of environmental factors, and pharmacotherapy. Several national quality measures are used to measure asthma care. The National Healthcare Quality & Disparities reports measure use of drugs, routine examinations, smoking cessation, influenza vaccination, emergency department visits, and urgent ambulatory visits. Electronic health records can be used to create asthma registries to identify patients who are at higher risk of exacerbations. Interventions that have been shown to improve asthma outcomes include asthma self-management and education, risk stratification of asthma patients, and improvement of drug adherence. Providing asthma education for patients and family members has been shown to decrease hospitalizations and emergency department visits. PMID:23767417

    Ingrown nail surgery is the one of the most common surgeries in outpatient clinics that are generally perfomed in response to patient complaints. Still, making simple observations, taking patient histories and conducting further tests are often neglected by outpatient clinics. Consequently, it is important to be aware if ingrown nail is associated with any underlying diseases that can lead to major complications. In this article, we report on two cases ending in amputation that were performed with Winograd’s partial matrix excision procedure for ingrown nails. Such a complication is rare, unexpected, and most unwanted in forefoot surgery. After a detailed analysis of the situation, we discovered that both patients were smokers, and one of them had Buerger’s disease. These conditions led to the ingrown nails in addition to poor wound healing. This case report emphasizes the fact that even when performing minor procedures, obtaining a detailed history and conducting an examination are of paramount importance. Patient selection is also a considerable factor, especially for patients who are smokers, who may experience a worst case surgical scenario. PMID:26693080

    In the last decade, the organization of pharmaceutical research on neglected tropical diseases has undergone transformative change. In a context of perceived “market failure,” the development of new medicines is increasingly handled by public-private partnerships. This shift toward hybrid organizational models depends on a particular form of exchange: the sharing of proprietary assets in general and of intellectual property rights in particular. This article explores the paradoxical role of private property in this new configuration of global health research and development. Rather than a tool to block potential competitors, proprietary assets function as a lever to attract others into risky collaborative ventures; instead of demarcating public and private domains, the sharing of property rights is used to increase the porosity of that boundary. This reimagination of the value of property is connected to the peculiar timescape of global health drug development, a promissory orientation to the future that takes its clearest form in the centrality of “virtual” business models and the proliferation of strategies of deferral. Drawing on the anthropological literature on inalienable possessions, we reconsider property’s traditional exclusionary role and discuss the possibility that the new pharmaceutical “commons” proclaimed by contemporary global health partnerships might be the precursor of future enclosures.

    Dissecting the characteristics of the transcription factor (TF) regulatory subpathway is helpful for understanding the TF underlying regulatory function in complex biological systems. To gain insight into the influence of TFs on their regulatory subpathways, we constructed a global TF-subpathways network (TSN) to analyze systematically the regulatory effect of common-motif, common-family, or common-tissue TFs on subpathways. We performed cluster analysis to show that the common-motif, common-family, or common-tissue TFs that regulated the same pathway classes tended to cluster together and contribute to the same biological function that led to disease initiation and progression. We analyzed the Jaccard coefficient to show that the functional consistency of subpathways regulated by the TF pairs with common motif, common family, or common tissue was significantly greater than the random TF pairs at the subpathway level, pathway level, and pathway class level. For example, HNF4A (hepatocyte nuclear factor 4, alpha) and NR1I3 (nuclear receptor subfamily 1, group I, member 3) were a pair of TFs with common motif, common family, and common tissue. They were involved in drug metabolism pathways and were liver-specific factors required for physiological transcription. In short, we inferred that the cofunctional subpathways were regulated by common-motif, common-family, or common-tissue TFs. PMID:26688819

    Among the billions of planetary systems that fill the Universe, we would like to know how ours fits in. Exoplanet data can already be used to address the question: How common are Jupiters? Here we discuss a simple analysis of recent exoplanet data indicating that Jupiter is a typical massive planet rather than an outlier. A more difficult question to address is: How common are Earths? However, much indirect evidence suggests that wet rocky planets are common.

    A number of different hardware elements were examined for possible Moon/Mars program commonality. These include manned landers; cargo landers, a trans-Mars injection (TMI) stage, traverse vehicles, unmanned surface rovers, habitation modules, and power supplies. Preliminary analysis indicates that it is possible to build a common two-stage manned lander. A single-stage, reusable lander may be practical for the lunar cast, but much less so for the Martian case, and commonality may therefore exist only at the subsystem level. A modified orbit transfer vehicle was examined as a potential cargo lander. Potential cargoes to various destinations were calculated for a Shuttle external tank sized TMI stage. A nuclear powered, long range traverse vehicle was conceptually designed and commonality is considered feasible. Short range, unmanned rovers can be made common without great effort. A surface habitation module may be difficult to make common due to difficulties in landing certain shapes on the Martian surface with aerobraking landers. Common nuclear power sources appear feasible. High temperature radiators appear easy to make common. Low temperature radiators may be difficult to make common. In most of these cases, Martian requirements determine the design.

  20. How Common is Common Use Facilities at Airports

    NASA Astrophysics Data System (ADS)

    Barbeau, Addison D.

    This study looked at common use airports across the country and at the implementation of common use facailities at airports. Common use consists of several elements that maybe installed at an airport. One of the elements is the self-service kiosks that allow passengers to have a faster check-in process, therefore moving them more quickly within the airport. Another element is signage and the incorporation of each airline's logo. Another aspect of common useis an airport regaining control of terminal gates by reducing the number of gates that are exclusively leased to a specific air carrier. This research focused on the current state of the common use facilities across the United States and examines the advantages and disadvantages of this approach. The research entailed interviews with personnel at a wide range of airports and found that each airport is in a different stage of implementation; some have fully implemented the common use concept while others are in the beginning stages of implementation. The questions were tailored to determine what the advantages and disadvantages are of a common use facility. The most common advantages reported included flexibility and cost. In the commom use system the airport reserves the right to move any airline to a different gate at any time for any reason. In turn, this helps reduce gates delays at that facility. For the airports that were interviewed no major disadvantages were reported. One down side of common use facilities for the airport involved is the major capital cost that is required to move to a common use system.

    Among the artiodactyla, the suids are a group whose digestive physiology has hardly been investigated. The apparent digestibilities (aD) of macronutrients were measured in captive specimens of warthog (Phacochoerus africanus), red river hog (Potamochoerus porcus), and Visayan warty pigs (Sus cebifrons), and compared with those reported for babirusa (Babyrousa babyrussa) from the same facility on a similar diet. The animals were fed mixed diets of pelleted feed, grains, fruits, and vegetables; dietary neutral detergent fiber (NDF) ranged from 17 to 26% dry matter. aD of organic matter and protein ranged from 72 to 89 and 70 to 82%, respectively. Although red river hogs and warty pigs achieved aD of NDF of 41-54%, this value was higher both in warthogs (63-66%) and babirusa (61-63%). aD of acid detergent fiber was comparatively low in red river hogs (4%), warty pigs (22%), and babirusa (13-25%) but high in warthog (59-62%). Comparison with additional literature data (including peccaries) indicates that in spite of differences in digestive anatomy, suids and peccaries are similar, and resemble other herbivores in fundamental characteristics, such as the negative influence of fiber on overall digestibility, or the positive influence of dietary protein on protein digestion. Although the existing data are equivocal as to a superior fiber digestion in peccaries as compared with other wild suids, the results suggest that warthogs are more efficient than other wild suids or peccaries in terms of fiber digestion.

    Heart failure (HF) is a common disease with high morbidity and mortality; however, none of the drugs available are now entirely optimal for the treatment of HF. In addition to various clinical diseases and environment influences, genetic factors also contribute to the development and progression of HF. Identifying the common variants for HF by genome-wide association studies will facilitate the understanding of pathophysiological mechanisms underlying HF. This review summarizes the recently identified common variants for HF risk and outcome and discusses their implications for the clinic therapy. PMID:26085806

  19. Casuistry as common law morality.

    PubMed

    Paulo, Norbert

    2015-12-01

    This article elaborates on the relation between ethical casuistry and common law reasoning. Despite the frequent talk of casuistry as common law morality, remarks on this issue largely remain at the purely metaphorical level. The article outlines and scrutinizes Albert Jonsen and Stephen Toulmin's version of casuistry and its basic elements. Drawing lessons for casuistry from common law reasoning, it is argued that one generally has to be faithful to ethical paradigms. There are, however, limitations for the binding force of paradigms. The most important limitations-the possibilities of overruling and distinguishing paradigm norms-are similar in common law and in casuistry, or so it is argued. These limitations explain why casuistry is not necessarily overly conservative and conventional, which is one line of criticism to which casuists can now better respond. Another line of criticism has it that the very reasoning from case to case is extremely unclear in casuistry. I suggest a certain model of analogical reasoning to address this critique. All my suggestions to understand and to enhance casuistry make use of common law reasoning whilst remaining faithful to Jonsen and Toulmin's main ideas and commitments. Further developed along these lines, casuistry can appropriately be called "common law morality." PMID:26576963

    One hundred and seventy one serum samples from 10 game species from Zimbabwe were tested for IgG antibodies to Toxoplasma gondii infection using the modified agglutination test (MAT). Significantly higher seroprevalences were found in the felidae (Panthera leo) (92% of 26), bovidae (Tragelaphus species) (55.9% of 34) and farm-reared struthionidae (Struthio camelus) (48% of 50) compared to the other groups tested. Among the bovidae, the nyala (Tragelaphus angasii) had the highest seroprevalence of 90% (9/10). Anti-Toxoplasma antibody prevalences in browsers [greater kudu (Tragelaphus strepsiceros) (20% of 10), giraffe (Giraffa camelopardalis) (10% of 10) and elephant (Loxodonta africana) (10% of 20)] were generally in the lower range. No antibodies were detected in the wild African suidae [warthog (Phacochoerus africanus) and bushpig (Potamochoerus larvatus)]. Attempts to isolate T. gondii from the heart muscles of seropositve ostriches by subinoculation in BALB/c mice were unsuccessful. PMID:15777687

    A total of 7 stocks of Trypanosoma brucei subspecies, isolated from naturally infected game animals in the Luangwa Valley, Eastern Province, Zambia were examined using a modified version of the Blood Incubation Infectivity Test (BIIT). One stock giving consistent BIIT responses typical of T.b. rhodesiense, was obtained from warthog (Phacochoerus aethiopicus). Four other stocks, 2 from hyaena (Crocuta crocuta), 1 from a waterbuck (Kobus ellipsiprymnus) and 1 from a lion (Panthera leo) responded like T.b. brucei. One stock from a waterbuck and 1 from a giraffe (Giraffa camelopardalis) failed to infect mice after incubation in human serum for 30 min at 37 degrees C when first tested, but after 5 or 6 further serial passages in mice and even with serum incubation time increased to 5 h, they retained infectivity.

    Trypomastogotes of Trypanosoma brucei were detected from 4 asymptomatic kudus (Tragelaphus strepsiceros) on a game ranch located approximately 45 km north east of Lusaka, Zambia. Blood smears examined from 14 wildlife species comprising of the impala (Aepyceros melampus), Kafue lechwe (kobus leche kafuensis), sable antelope (Hippotragus niger), tsessebe (Damaliscus lunatus), warthog (Phacochoerus aethiopicus), puku (Kobus vardoni), zebra (Equus burchelli), waterbuck (Kobus ellipsiprymnus), bushbuck (Tragelaphus scriptus), reedbuck (Redunca arundinum), wilderbeest (Connochaetes taurinus), hartebeest (Alcephelus lichtensteini), African buffalo (Syncerus caffer), and kudu (Tragelaphus strepsiceros) showed that only the kudu had T. brucei. Although game ranching has emerged to be a successful ex-situ conservation strategy aimed at saving the declining wildlife population in the National Parks, our findings suggest that it has the potential of aiding the re-distribution of animal diseases. Hence, there is a need for augmenting wildlife conservation with disease control strategies aimed at reducing the risk of disease transmission between wildlife and domestic animals. PMID:20333288

  3. Garlic for the common cold.

    Lissiman, Elizabeth; Bhasale, Alice L; Cohen, Marc

    2014-01-01

    Background Garlic is alleged to have antimicrobial and antiviral properties that relieve the common cold, among other beneficial effects. There is widespread usage of garlic supplements. The common cold is associated with significant morbidity and economic consequences. On average, children have six to eight colds per year and adults have two to four.Objectives To determine whether garlic (Allium sativum) is effective for the prevention or treatment of the common cold, when compared to placebo, no treatment or other treatments.Search methods We searched CENTRAL (2014, Issue 7),OLDMEDLINE (1950 to 1965),MEDLINE (January 1966 to July week 5, 2014), EMBASE(1974 to August 2014) and AMED (1985 to August 2014).Selection criteria Randomised controlled trials of common cold prevention and treatment comparing garlic with placebo, no treatment or standard treatment.Data collection and analysis Two review authors independently reviewed and selected trials from searches, assessed and rated study quality and extracted relevant data.Main results In this updated review, we identified eight trials as potentially relevant from our searches. Again, only one trial met the inclusion criteria.This trial randomly assigned 146 participants to either a garlic supplement (with 180 mg of allicin content) or a placebo (once daily)for 12 weeks. The trial reported 24 occurrences of the common cold in the garlic intervention group compared with 65 in the placebo group (P value < 0.001), resulting in fewer days of illness in the garlic group compared with the placebo group (111 versus 366). The number of days to recovery from an occurrence of the common cold was similar in both groups (4.63 versus 5.63). Only one trial met the inclusion criteria, therefore limited conclusions can be drawn. The trial relied on self reported episodes of the common cold but was of reasonable quality in terms of randomisation and allocation concealment. Adverse effects included rash and odour. Authors' conclusions There is insufficient clinical trial evidence regarding the effects of garlic in preventing or treating the common cold. A single trial suggested that garlic may prevent occurrences of the common cold but more studies are needed to validate this finding. Claims of effectiveness appear to rely largely on poor-quality evidence. PMID:25386977

    The proper object of global health governance (GHG) should be the common good, ensuring that all people have the opportunity to flourish. A well-organized global society that promotes the common good is to everyone's advantage. Enabling people to flourish includes enabling their ability to be healthy. Thus, we must assess health governance by its effectiveness in enhancing health capabilities. Current GHG fails to support human flourishing, diminishes health capabilities and thus does not serve the common good. The provincial globalism theory of health governance proposes a Global Health Constitution and an accompanying Global Institute of Health and Medicine that together propose to transform health governance. Multiple lines of empirical research suggest that these institutions would be effective, offering the most promising path to a healthier, more just world. PMID:26122555

    Many regulatory genes appear to be utilized in at least superficially similar ways in the development of particular body parts in Drosophila and in chordates. These similarities have been widely interpreted as functional homologies, producing the conventional view of the last common protostome-deuterostome ancestor (PDA) as a complex organism that possessed some of the same body parts as modern bilaterians. Here we discuss an alternative view, in which the last common PDA had a less complex body plan than is frequently conceived. This reconstruction alters expectations for Neoproterozoic fossil remains that could illustrate the pathways of bilaterian evolution.

    2007-02-15

    The common cold is a viral illness that affects persons of all ages, prompting frequent use of over-the-counter and prescription medications and alternative remedies. Treatment focuses on relieving symptoms (e.g., cough, nasal congestion, rhinorrhea). Dextromethorphan may be beneficial in adults with cough, but its effectiveness has not been demonstrated in children and adolescents. Codeine has not been shown to effectively treat cough caused by the common cold. Although hydrocodone is widely used and has been shown to effectively treat cough caused by other conditions, the drug has not been studied in patients with colds. Topical (intranasal) and oral nasal decongestants have been shown to relieve nasal symptoms and can be used in adolescents and adults for up to three days. Antihistamines and combination antihistamine/decongestant therapies can modestly improve symptoms in adults; however, the benefits must be weighed against potential side effects. Newer nonsedating antihistamines are ineffective against cough. Topical ipratropium, a prescription anticholinergic, relieves nasal symptoms in older children and adults. Antibiotics have not been shown to improve symptoms or shorten illness duration. Complementary and alternative therapies (i.e., Echinacea, vitamin C, and zinc) are not recommended for treating common cold symptoms; however, humidified air and fluid intake may be useful without adverse side effects. Vitamin C prophylaxis may modestly reduce the duration and severity of the common cold in the general population and may reduce the incidence of the illness in persons exposed to physical and environmental stresses.

  3. Common sleep disorders in children.

    2014-03-01

    Up to 50% of children will experience a sleep problem. Early identification of sleep problems may prevent negative consequences, such as daytime sleepiness, irritability, behavioral problems, learning difficulties, motor vehicle crashes in teenagers, and poor academic performance. Obstructive sleep apnea occurs in 1% to 5% of children. Polysomnography is needed to diagnose the condition because it may not be detected through history and physical examination alone. Adenotonsillectomy is the primary treatment for most children with obstructive sleep apnea. Parasomnias are common in childhood; sleepwalking, sleep talking, confusional arousals, and sleep terrors tend to occur in the first half of the night, whereas nightmares are more common in the second half of the night. Only 4% of parasomnias will persist past adolescence; thus, the best management is parental reassurance and proper safety measures. Behavioral insomnia of childhood is common and is characterized by a learned inability to fall and/or stay asleep. Management begins with consistent implementation of good sleep hygiene practices, and, in some cases, use of extinction techniques may be appropriate. Delayed sleep phase disorder is most common in adolescence, presenting as difficulty falling asleep and awakening at socially acceptable times. Treatment involves good sleep hygiene and a consistent sleep-wake schedule, with nighttime melatonin and/or morning bright light therapy as needed. Diagnosing restless legs syndrome in children can be difficult; management focuses on trigger avoidance and treatment of iron deficiency, if present. PMID:24695508

  4. The Common Geometry Module (CGM).

    Tautges, Timothy James

    2004-12-01

    The Common Geometry Module (CGM) is a code library which provides geometry functionality used for mesh generation and other applications. This functionality includes that commonly found in solid modeling engines, like geometry creation, query and modification; CGM also includes capabilities not commonly found in solid modeling engines, like geometry decomposition tools and support for shared material interfaces. CGM is built upon the ACIS solid modeling engine, but also includes geometry capability developed beside and on top of ACIS. CGM can be used as-is to provide geometry functionality for codes needing this capability. However, CGM can also be extended using derived classes in C++, allowing the geometric model to serve as the basis for other applications, for example mesh generation. CGM is supported on Sun Solaris, SGI, HP, IBM, DEC, Linux and Windows NT platforms. CGM also includes support for loading ACIS models on parallel computers, using MPI-based communication. Future plans for CGM are to port it to different solid modeling engines, including Pro/Engineer or SolidWorks. CGM is being released into the public domain under an LGPL license; the ACIS-based engine is available to ACIS licensees on request.

  5. Scientific Research: Commodities or Commons?

    NASA Astrophysics Data System (ADS)

    Vermeir, Koen

    2013-10-01

    Truth is for sale today, some critics claim. The increased commodification of science corrupts it, scientific fraud is rampant and the age-old trust in science is shattered. This cynical view, although gaining in prominence, does not explain very well the surprising motivation and integrity that is still central to the scientific life. Although scientific knowledge becomes more and more treated as a commodity or as a product that is for sale, a central part of academic scientific practice is still organized according to different principles. In this paper, I critically analyze alternative models for understanding the organization of knowledge, such as the idea of the scientific commons and the gift economy of science. After weighing the diverse positive and negative aspects of free market economies of science and gift economies of science, a commons structured as a gift economy seems best suited to preserve and take advantage of the specific character of scientific knowledge. Furthermore, commons and gift economies promote the rich social texture that is important for supporting central norms of science. Some of these basic norms might break down if the gift character of science is lost. To conclude, I consider the possibility and desirability of hybrid economies of academic science, which combine aspects of gift economies and free market economies. The aim of this paper is to gain a better understanding of these deeper structural challenges faced by science policy. Such theoretical reflections should eventually assist us in formulating new policy guidelines.

  6. Common Rail Injection System Development

    SciTech Connect

    Electro-Motive,

    2005-12-30

    The collaborative research program between the Department of energy and Electro-Motive Diesels, Inc. on the development of common rail fuel injection system for locomotive diesel engines that can meet US EPA Tier 2 exhaust emissions has been completed. This final report summarizes the objectives of the program, work scope, key accomplishments and research findings. The major objectives of this project encompassed identification of appropriate injection strategies by using advanced analytical tools, development of required prototype hardware/controls, investigations of fuel spray characteristics including cavitation phenomena, and validation of hareware using a single-cylinder research locomotive diesel engine. Major milestones included: (1) a detailed modeling study using advanced mathematical models - several various injection profiles that show simultaneous reduction of NOx and particulates on a four stroke-cycle locomotive diesel engine were identified; (2) development of new common rail fuel injection hardware capable of providing these injection profiles while meeting EMD engine and injection performance specifications. This hardware was developed together with EMD's current fuel injection component supplier. (3) Analysis of fuel spray characteristics. Fuel spray numerical studies and high speed photographic imaging analyses were performed. (4) Validation of new hardware and fuel injection profiles. EMD's single-cylinder research diesel engine located at Argonne National Laboratory was used to confirm emissions and performacne predictions. These analytical ane experimental investigations resulted in optimized fuel injection profiles and engine operating conditions that yield reductions in NOx emissions from 7.8 g/bhp-hr to 5.0 g/bhp-hr at full (rated) load. Additionally, hydrocarbon and particulate emissions were reduced considerably when compared to baseline Tier I levels. The most significant finding from the injection optimization process was a 2% to 3% improvement in fuel economy over EMD's traditional Tier I engine hardware configuration. the common rail fuel injection system enabled this added benefit by virtue of an inherent capability to provide multiple injections per power stroke at high fuel rail pressures. On the basis of the findings in this study, EMD concludes that the new electronically-controlled high-pressure common rail injection system has the potential to meet locomotive Tier 2 NOx and particulates emission standards without sacrificing the fuel economy. A number of areas to further improve the injection hardware and engine operating characteristics to further exploit the benefits of common rail injection system have also been identified.

    Newbury, Amy B. (Inventor)

    2010-01-01

    The present invention relates to a dispersive spectrometer. The spectrometer allows detection of multiple orders of light on a single focal plane array by splitting the orders spatially using a dichroic assembly. A conventional dispersion mechanism such as a defraction grating disperses the light spectrally. As a result, multiple wavelength orders can be imaged on a single focal plane array of limited spectral extent, doubling (or more) the number of spectral channels as compared to a conventional spectrometer. In addition, this is achieved in a common path device.

  11. Vibrios Commonly Possess Two Chromosomes

    2005-01-01

    The prevalence of the two-chromosome configuration was investigated in 34 species of vibrios and closely related species. Pulsed-field gel electrophoresis of undigested genomic DNA suggested that vibrios commonly have two chromosomes. The size of the large chromosome is predominantly within a narrow range (3.0 to 3.3 Mb), whereas the size of the small chromosome varies considerably among the vibrios (0.8 to 2.4 Mb). This fact suggests that the structure of the small chromosome is more flexible than that of the large chromosome during the evolution of vibrios. PMID:15629946

  12. Evolution of a common controller

    Powell, D.; Barbour, D.; Gilbreath, G.

    2012-06-01

    Precedent has shown common controllers must strike a balance between the desire for an integrated user interface design by human factors engineers and support of project-specific data requirements. A common user-interface requires the project-specific data to conform to an internal representation, but project-specific customization is impeded by the implicit rules introduced by the internal data representation. Space and Naval Warfare Systems Center Pacific (SSC Pacific) developed the latest version of the Multi-robot Operator Control Unit (MOCU) to address interoperability, standardization, and customization issues by using a modular, extensible, and flexible architecture built upon a sharedworld model. MOCU version 3 provides an open and extensible operator-control interface that allows additional functionality to be seamlessly added with software modules while providing the means to fully integrate the information into a layered game-like user interface. MOCU's design allows it to completely decouple the human interface from the core management modules, while still enabling modules to render overlapping regions of the screen without interference or a priori knowledge of other display elements, thus allowing more flexibility in project-specific customization.

  13. Common Skin Rashes in Children.

    PubMed

    Allmon, Amanda; Deane, Kristen; Martin, Kari L

    2015-08-01

    Because childhood rashes may be difficult to differentiate by appearance alone, it is important to consider the entire clinical presentation to help make the appropriate diagnosis. Considerations include the appearance and location of the rash; the clinical course; and associated symptoms, such as pruritus or fever. A fever is likely to occur with roseola, erythema infectiosum (fifth disease), and scarlet fever. Pruritus sometimes occurs with atopic dermatitis, pityriasis rosea, erythema infectiosum, molluscum contagiosum, and tinea infection. The key feature of roseola is a rash presenting after resolution of a high fever, whereas the distinguishing features in pityriasis rosea are a herald patch and a bilateral and symmetric rash in a Christmas tree pattern. The rash associated with scarlet fever usually develops on the upper trunk, then spreads throughout the body, sparing the palms and soles. Impetigo is a superficial bacterial infection that most commonly affects the face and extremities of children. Erythema infectiosum is characterized by a viral prodrome followed by the "slapped cheek" facial rash. Flesh-colored or pearly white papules with central umbilication occur with molluscum contagiosum, a highly contagious viral infection that usually resolves without intervention. Tinea is a common fungal skin infection in children that affects the scalp, body, groin, feet, hands, or nails. Atopic dermatitis is a chronic, relapsing inflammatory skin condition that may present with a variety of skin changes. PMID:26280141

    Araya, M.; Avarias, J.; Mora, M.; Tobar, R.

    The ACS-UTFSM Group was created as a distributed systems research team on astronomical and non-astronomical applications on the year 2004. The choice of the ALMA Common Software framework (ACS) as the development platform came from the experience gained during summerjobs at ESO observatories. After three years of informal contributions to ACS development, the team presented a technology exchange initiative to the ALMA-CONICYT Fund 2006, which was granted in 2007. Through the past years, the UTFSM helped the ACS team with "nice-to-have" applications and testing. Currently the ACS-UTFSM is involved in several contributions to ACS, and the development of a flexible telescope control system (gTCS) framework which aims to encapsulate common requirements and will provide a uniform software. In preparation for this challenging objective, several small projects are currently being developed. The other interesting edge of the team work is the technology transfer initiatives. Several inter-universities collaborations are flourishing (PUC, UCN, UV) after the first ACS Workshop held at the UTFSM this year. Today three former team members are working at NRAO's ALMA Test Facility in Socorro, New Mexico. Two other students will have a summer job next year to work in ALMA related development.

    2000-07-01

    Seventy-five patients of both sexes with clinically suspected contact dermatitis were patch tested with the Indian Standard Series and indigenous antigens. The results were compared with the data from other centers. Most of these patients were young adults between 20 and 39 yrs old with the mean age of 36.63 +/- 5.6 yrs. Their occupational profiles included household workers (17.33%), masons (10.66%), farmers (6.66%), factory workers (4%), medical personnel (4%), lab workers (2.66%), and miscellaneous (17.33%). Itching and burning were two of the most common complaints, and chronic dermatitis was the predominant morphologic pattern of the lesions observed. Frequent sites involved included the hands (40.83%), airborne type (22.44%), hands and feet (12.24%), feet (12.24%), face (10.2%), and neck (2.04%). Patch test analysis of these patients revealed that, out of 75 subjects tested, 49 (65.3%) reacted to one or more allergens. Parthenium (20%) is the most common contact sensitizer followed by potassium dichromate (16%), xanthium (13.33%), nickel sulphate (12%), chrysanthemum (8%), mercaptobenzothiazole, and garlic (6.66% each). These findings are in broad conformity with those in other reports. We concluded that the Indian Standard Series of antigens with the addition of a few more (such as garlic, onion and chlorheximide of local relevance) is suitable for detecting the allergens responsible for the contact dermatitis prevailing in this region.

    An investigation on human-herbivore conflict was carried out in CCNP between 2011 and 2012 in seven randomly selected villages (Chebera, Serri, Yora, Shita, Delba, Chuchra, Chewda) around the Park. A total of 312 household samples were identified for interview. Group discussion and field observation were also carried out. Among the respondents, the majority (83.9%) faced crop damage. African elephant (Loxodonta africana), Hippopotamus (Hippopotamus amphibious), African buffalo (Syncerus caffer), Desert warthog (Phacochoerus aethiopicus), Wild pig (Sus scrofa), Porcupine (Hystrix cristata), Vervet monkey (Cercopithecus aethiops) and Anubis baboon (Papio anubis) were identified as the most problematic animals in the area. However, buffalo, monkey and warthog were considered as the notorious pest. Crop damage and threats to human safety were the major problems encountered resulting in conflict between human and wildlife. Most respondents had a negative attitude towards the problem-posing animals. This will lead to a change in public attitude from one that supports wildlife conservation to sees wild herbivores as a threat and a potential negative consequence for wildlife conservation. Active measures have to be implemented to solve the problems and safeguard the future of the wildlife management in the park. PMID:24506044

    2015-10-31

    Motility is characteristic of life, but a common basis for movement has remained to be identified. Diverse systems in motion shift between two states depending on interactions that turnover at the rate of an applied cycle of force. Although one phase of the force cycle terminates the decay of the most recent state, continuation of the cycle of force regenerates the original decay process in a recursive cycle. By completing a cycle, kinetic energy is transformed into probability of sustaining the most recent state and the system gains a frame of reference for discrete transitions having static rather than time-dependent probability. The probability of completing a recursive cycle is computed with a Markov chain comprised of two equilibrium states and a kinetic intermediate. Given rate constants for the reactions, a random walk reproduces bias and recurrence times of walking motor molecules and bacterial flagellar switching with unrivaled fidelity.

    Toxicology is a vast subject. Animals are exposed to numerous drugs, household products, plants, chemicals, pesticides and venomous animals. In addition to the individual toxicity of the various potential poisons, there is also the question of individual response and, more importantly, of species differences in toxicity. This review serves to address some of the common questions asked when dealing with animals with possible poisoning, providing evidence where available. The role of emetics, activated charcoal and lipid infusion in the management of poisoning in animals, the toxic dose of chocolate, grapes and dried fruit in dogs, the use of antidotes in paracetamol poisoning, timing of antidotal therapy in ethylene glycol toxicosis and whether lilies are toxic to dogs are discussed.

  19. The Common Patterns of Nature

    PubMed Central

    Frank, Steven A.

    2010-01-01

    We typically observe large-scale outcomes that arise from the interactions of many hidden, small-scale processes. Examples include age of disease onset, rates of amino acid substitutions, and composition of ecological communities. The macroscopic patterns in each problem often vary around a characteristic shape that can be generated by neutral processes. A neutral generative model assumes that each microscopic process follows unbiased or random stochastic fluctuations: random connections of network nodes; amino acid substitutions with no effect on fitness; species that arise or disappear from communities randomly. These neutral generative models often match common patterns of nature. In this paper, I present the theoretical background by which we can understand why these neutral generative models are so successful. I show where the classic patterns come from, such as the Poisson pattern, the normal or Gaussian pattern, and many others. Each classic pattern was often discovered by a simple neutral generative model. The neutral patterns share a special characteristic: they describe the patterns of nature that follow from simple constraints on information. For example, any aggregation of processes that preserves information only about the mean and variance attracts to the Gaussian pattern; any aggregation that preserves information only about the mean attracts to the exponential pattern; any aggregation that preserves information only about the geometric mean attracts to the power law pattern. I present a simple and consistent informational framework of the common patterns of nature based on the method of maximum entropy. This framework shows that each neutral generative model is a special case that helps to discover a particular set of informational constraints; those informational constraints define a much wider domain of non-neutral generative processes that attract to the same neutral pattern.

  20. Work and common psychiatric disorders.

    PubMed

    Henderson, M; Harvey, S B; Overland, S; Mykletun, A; Hotopf, M

    2011-05-01

    Psychiatric disorders are now the most common reason for long-term sickness absence. The associated loss in productivity and the payment of disability benefits places a substantial burden on the economies of many developed countries. The occupational dysfunction associated with psychiatric disorders can also lead to poverty and social isolation. As a result the area of work and psychiatric disorders is a high priority for policymakers. There are two main agendas: for many researchers and clinicians the focus is on the need to overcome stigma and ensure people with severe psychiatric disorders have meaningful work; however the public health agenda predominantly relates to the more common disorders such as depression and anxiety, which contribute a greater burden of disability benefits and pensions. In this review we attempt to address this second agenda. The relatively sparse evidence available reveals a complex field with significant interplay between medical, psychological social and cultural factors. Sick leave can be a 'process' as well as an 'event'. In this review we propose a staged model where different risk and protective factors contribute to the onset of psychiatric disorders in the working population, the onset of short-term sickness absence, and the transition from short- to long-term absence. We also examine strategies to manage psychiatric disorder in the workforce with a view towards returning the employee to work. Our aim in this review is to highlight the complexity of the area, to stimulate debate and to identify important gaps in knowledge where further research might benefit both patients and wider society.

    1. Rainfall is the prime climatic factor underpinning the dynamics of African savanna ungulates, but no study has analysed its influence on the abundance of these ungulates at monthly to multiannual time scales. 2. We report relationships between rainfall and changes in age- and sex-structured abundances of seven ungulate species monitored monthly for 15 years using vehicle ground counts in the Maasai Mara National Reserve, Kenya. 3. Abundance showed strong and curvilinear relationships with current and cumulative rainfall, with older topi, Damaliscus korrigum (Ogilby); warthog, Phacochoerus aethiopicus (Pallas); waterbuck, Kobus ellipsyprimnus (Ogilby); and impala, Aepyceros melampus (Lichtenstein) responding to longer lags than younger animals, portraying carryover effects of prior habitat conditions. 4. The abundances of newborn calves were best correlated with monthly rainfall averaged over the preceding 5-6 months for topi, waterbuck, warthog, and 2 months for the migratory zebra Equus burchelli (Gray), but with seasonal rainfall averaged over 2-5 years for giraffe, Giraffa camelopardalis (L.); impala; and kongoni, Alcelaphus busephalus (Pallas). The cumulative late wet-season rainfall was the best predictor of abundance for quarter- to full-grown animals for most species. Monthly rainfall exerted both negative and positive effects on the abundances of zebra, impala and waterbuck. Ignoring age, both sexes responded similarly to rainfall. 5. Births were strongly seasonal only for warthog and topi, but peaked between August and December for most species. Hence abundance was strongly seasonal for young topi and warthog and the migratory zebra. Pronounced seasonality in births for warthog and topi obliterated otherwise strong relationships between abundance and rainfall when both month and rainfall were included in the same model. Aggregated density produced relationships with rainfall similar to those for fully grown animals, emphasizing the necessity of demographic monitoring to reliably reveal rainfall influences on ungulate abundance in the Mara. 6. Strong relationships between abundance and rainfall suggest that rainfall underpins the dynamics of African savanna ungulates, and that changes in rainfall due to global warming may markedly alter the abundance and diversity of these mammals. Ungulates respond to rainfall fluctuations through movements, reproduction or survival, and the responses appear independent of breeding phenology and synchrony, dietary guild, or degree of water dependence. Newborns and adults have contrasting responses to rainfall. Males and females respond similarly to rainfall when age is ignored. PMID:18422558

    Patients will experience a wide range of skin growths and changes over their lifetime. Family physicians should be able to distinguish potentially malignant from benign skin tumors. Most lesions can be diagnosed on the basis of history and clinical examination. Lesions that are suspicious for malignancy, those with changing characteristics, symptomatic lesions, and those that cause cosmetic problems may warrant medical therapy, a simple office procedure (e.g., excision, cryosurgery, laser ablation), or referral. Acrochordons are extremely common, small, and typically pedunculated benign neoplasms. Simple scissor or shave excision, electrodesiccation, or cryosurgery can be used for treatment. Sebaceous hyperplasia presents as asymptomatic, discrete, soft, pale yellow, shiny bumps on the forehead or cheeks, or near hair follicles. Except for cosmesis, they have no clinical significance. Lipomas are soft, flesh-colored nodules that are easily moveable under the overlying skin. Keratoacanthomas are rapidly growing, squamoproliferative benign tumors that resemble squamous cell carcinomas. Early simple excision is recommended. Pyogenic granuloma is a rapidly growing nodule that bleeds easily. Treatment includes laser ablation or shave excision with electrodesiccation of the base. Dermatofibromas are an idiopathic benign proliferation of fibroblasts. No treatment is required unless there is a change in size or color, bleeding, or irritation from trauma. Epidermal inclusion cysts can be treated by simple excision with removal of the cyst and cyst wall. Seborrheic keratoses and cherry angiomas generally do not require treatment. PMID:26447443

  3. On the common envelope efficiency

    2014-08-01

    In this work, we try to use the apparent luminosity versus displacement (i.e. LX versus R) correlation of high-mass X-ray binaries (HMXBs) to constrain the common envelope (CE) efficiency ?CE, which is a key parameter affecting the evolution of the binary orbit during the CE phase. The major updates that are crucial for the CE evolution include a variable ? parameter and a new CE criterion for Hertzsprung gap donor stars, both of which are recently developed. We find that, within the framework of the standard energy formula for CE and core definition at mass X = 10 per cent, a high value of ?CE, i.e. around 0.8-1.0, is more preferable, while ?CE < ˜0.4 likely can not reconstruct the observed LX versus R distribution. However, due to an ambiguous definition for the core boundary in the literature, the used ? here still carries almost two order of magnitude uncertainty, which may translate directly to the expected value of ?CE. We present the detailed components of current HMXBs and their spatial offsets from star clusters, which may be further testified by future observations of HMXB populations in nearby star-forming galaxies.

    Imtiaz, Kauser

    2011-01-01

    Common Bolted Joint Analysis Tool (comBAT) is an Excel/VB-based bolted joint analysis/optimization program that lays out a systematic foundation for an inexperienced or seasoned analyst to determine fastener size, material, and assembly torque for a given design. Analysts are able to perform numerous what-if scenarios within minutes to arrive at an optimal solution. The program evaluates input design parameters, performs joint assembly checks, and steps through numerous calculations to arrive at several key margins of safety for each member in a joint. It also checks for joint gapping, provides fatigue calculations, and generates joint diagrams for a visual reference. Optimum fastener size and material, as well as correct torque, can then be provided. Analysis methodology, equations, and guidelines are provided throughout the solution sequence so that this program does not become a "black box:" for the analyst. There are built-in databases that reduce the legwork required by the analyst. Each step is clearly identified and results are provided in number format, as well as color-coded spelled-out words to draw user attention. The three key features of the software are robust technical content, innovative and user friendly I/O, and a large database. The program addresses every aspect of bolted joint analysis and proves to be an instructional tool at the same time. It saves analysis time, has intelligent messaging features, and catches operator errors in real time.

  5. Common themes in microbial pathogenicity.

    PubMed Central

    Finlay, B B; Falkow, S

    1989-01-01

    A bacterial pathogen is a highly adapted microorganism which has the capacity to cause disease. The mechanisms used by pathogenic bacteria to cause infection and disease usually include an interactive group of virulence determinants, sometimes coregulated, which are suited for the interaction of a particular microorganism with a specific host. Because pathogens must overcome similar host barriers, common themes in microbial pathogenesis have evolved. However, these mechanisms are diverse between species and not necessarily conserved; instead, convergent evolution has developed several different mechanisms to overcome host barriers. The success of a bacterial pathogen can be measured by the degree with which it replicates after entering the host and reaching its specific niche. Successful microbial infection reflects persistence within a host and avoidance or neutralization of the specific and nonspecific defense mechanisms of the host. The degree of success of a pathogen is dependent upon the status of the host. As pathogens pass through a host, they are exposed to new environments. Highly adapted pathogenic organisms have developed biochemical sensors exquisitely designed to measure and respond to such environmental stimuli and accordingly to regulate a cascade of virulence determinants essential for life within the host. The pathogenic state is the product of dynamic selective pressures on microbial populations. PMID:2569162

  6. Space station utilization and commonality

    NASA Technical Reports Server (NTRS)

    Butler, John

    1986-01-01

    Several potential ways of utilizing the space station, including utilization of learning experiences (such as operations), utilization of specific elements of hardware which can be largely common between the SS and Mars programs, and utilization of the on-orbit SS for transportation node functions were identified and discussed. The probability of using the SS in all of these areas seems very good. Three different ways are discussed of utilizing the then existing Low Earth Orbit (LEO) SS for operational support during assembly and checkout of the Mars Space Vehicle (SV): attaching the SV to the SS; allowing the SV to co-orbit near the SS; and a hybrid of the first 2 ways. Discussion of each of these approaches is provided, and the conclusion is reached that either the co-orbiting or hybrid approach might be preferable. Artists' conception of the modes are provided, and sketches of an assembly system concept (truss structure and subsystems derivable from the SS) which could be used for co-orbiting on-orbit assembly support are provided.

  7. Managing the wildlife tourism commons.

    2015-04-01

    The nonlethal effects of wildlife tourism can threaten the conservation status of targeted animal populations. In turn, such resource depletion can compromise the economic viability of the industry. Therefore, wildlife tourism exploits resources that can become common pool and that should be managed accordingly. We used a simulation approach to test whether different management regimes (tax, tax and subsidy, cap, cap and trade) could provide socioecologically sustainable solutions. Such schemes are sensitive to errors in estimated management targets. We determined the sensitivity of each scenario to various realistic uncertainties in management implementation and in our knowledge of the population. Scenarios where time quotas were enforced using a tax and subsidy approach, or they were traded between operators were more likely to be sustainable. Importantly, sustainability could be achieved even when operators were assumed to make simple rational economic decisions. We suggest that a combination of the two regimes might offer a robust solution, especially on a small spatial scale and under the control of a self-organized, operator-level institution. Our simulation platform could be parameterized to mimic local conditions and provide a test bed for experimenting different governance solutions in specific case studies. PMID:26214918

  8. Common Syndromes of Orthostatic Intolerance

    PubMed Central

    2013-01-01

    The autonomic nervous system, adequate blood volume, and intact skeletal and respiratory muscle pumps are essential components for rapid cardiovascular adjustments to upright posture (orthostasis). Patients lacking sufficient blood volume or having defective sympathetic adrenergic vasoconstriction develop orthostatic hypotension (OH), prohibiting effective upright activities. OH is one form of orthostatic intolerance (OI) defined by signs, such as hypotension, and symptoms, such as lightheadedness, that occur when upright and are relieved by recumbence. Mild OI is commonly experienced during intercurrent illnesses and when standing up rapidly. The latter is denoted “initial OH” and represents a normal cardiovascular adjustment to the blood volume shifts during standing. Some people experience episodic acute OI, such as postural vasovagal syncope (fainting), or chronic OI, such as postural tachycardia syndrome, which can significantly reduce quality of life. The lifetime incidence of ?1 fainting episodes is ?40%. For the most part, these episodes are benign and self-limited, although frequent syncope episodes can be debilitating, and injury may occur from sudden falls. In this article, mechanisms for OI having components of adrenergic hypofunction, adrenergic hyperfunction, hyperpnea, and regional blood volume redistribution are discussed. Therapeutic strategies to cope with OI are proposed. PMID:23569093

  9. Natural host odours as possible attractants for Glossina tachinoides and G. longipalpis (Diptera: Glossinidae).

    PubMed

    Späth, J

    1997-11-01

    As strictly haematophagous insects, tsetse flies feed on a wide variety of wild and domestic animals. Although these are mainly mammals, some tsetse species also feed on reptiles. The present study investigated whether the odours of several potential natural tsetse hosts may be used as novel attractants to improve the catch of Glossina tachinoides or G. longipalpis in biconical traps. The odour of a living monitor lizard (Varanus niloticus) had no effect on the catch of G. tachinoides. Hexane skin washings of monitor lizard and warthog (Phacochoerus aethiopicus) dispensed in small quantities improved the catch of G. tachinoides significantly by factors of up to 1.34 and 1.46, respectively. Skin washing of bushbuck (Tragelaphus scriptus) did not increase the catch of G. tachinoides, but the synthetic phenolic fraction of bushbuck urine enhanced it significantly by 1.81 times. The catch of G. longipalpis was improved significantly by the urines of warthog, domestic pig and bushbuck by factors of 1.58, 1.91 and 2.51, respectively. In relation to the quantity of evaporated odour, bushbuck and warthog urine seem to be of particular interest for further attractant studies. The effect of tested host odours on the catch of G. tachinoides and G. longipalpis is compared with data of other tsetse species and with the frequency these hosts are fed on by tsetse flies. Bushbuck is one of the principal natural hosts of both Glossina species investigated, and of all odours tested, bushbuck urine and its synthetic phenolic fraction improved the catch of both tsetse species the most.

  10. Coordinating towards a Common Good

    Santos, Francisco C.; Pacheco, Jorge M.

    2010-09-01

    Throughout their life, humans often engage in collective endeavors ranging from family related issues to global warming. In all cases, the tragedy of the commons threatens the possibility of reaching the optimal solution associated with global cooperation, a scenario predicted by theory and demonstrated by many experiments. Using the toolbox of evolutionary game theory, I will address two important aspects of evolutionary dynamics that have been neglected so far in the context of public goods games and evolution of cooperation. On one hand, the fact that often there is a threshold above which a public good is reached [1, 2]. On the other hand, the fact that individuals often participate in several games, related to the their social context and pattern of social ties, defined by a social network [3, 4, 5]. In the first case, the existence of a threshold above which collective action is materialized dictates a rich pattern of evolutionary dynamics where the direction of natural selection can be inverted compared to standard expectations. Scenarios of defector dominance, pure coordination or coexistence may arise simultaneously. Both finite and infinite population models are analyzed. In networked games, cooperation blooms whenever the act of contributing is more important than the effort contributed. In particular, the heterogeneous nature of social networks naturally induces a symmetry breaking of the dilemmas of cooperation, as contributions made by cooperators may become contingent on the social context in which the individual is embedded. This diversity in context provides an advantage to cooperators, which is particularly strong when both wealth and social ties follow a power-law distribution, providing clues on the self-organization of social communities. Finally, in both situations, it can be shown that individuals no longer play a defection dominance dilemma, but effectively engage in a general N-person coordination game. Even if locally defection may seem inescapable, globally there is an emergent new dilemma in which cooperation often prevails, illustrating how collective cooperative action may emerge from myopic individual selfishness.

  11. Designing the Microbial Research Commons

    SciTech Connect

    Uhlir, Paul F

    2011-10-01

    Recent decades have witnessed an ever-increasing range and volume of digital data. All elements of the pillars of science--whether observation, experiment, or theory and modeling--are being transformed by the continuous cycle of generation, dissemination, and use of factual information. This is even more so in terms of the re-using and re-purposing of digital scientific data beyond the original intent of the data collectors, often with dramatic results. We all know about the potential benefits and impacts of digital data, but we are also aware of the barriers, the challenges in maximizing the access, and use of such data. There is thus a need to think about how a data infrastructure can enhance capabilities for finding, using, and integrating information to accelerate discovery and innovation. How can we best implement an accessible, interoperable digital environment so that the data can be repeatedly used by a wide variety of users in different settings and with different applications? With this objective: to use the microbial communities and microbial data, literature, and the research materials themselves as a test case, the Board on Research Data and Information held an International Symposium on Designing the Microbial Research Commons at the National Academy of Sciences in Washington, DC on 8-9 October 2009. The symposium addressed topics such as models to lower the transaction costs and support access to and use of microbiological materials and digital resources from the perspective of publicly funded research, public-private interactions, and developing country concerns. The overall goal of the symposium was to stimulate more research and implementation of improved legal and institutional models for publicly funded research in microbiology.

  12. Returning common sense to regulations

    SciTech Connect

    Fox, M.R.

    1995-10-01

    While these sessions of the November 1995 meeting of the American Nuclear Society are being devoted to the Linear Theory of harm from radiation, it must be realized that the low-level radiation issue, as important as it may be, is but a subset of an entire body of environmental issues running afoul of common sense. Cellular phones, electromagnetic fields, asbestos, dioxin, acid rain, and others especially in their public portrayals, some in their regulatory treatment, are based upon exaggerated or misunderstood risks. One must recognize that what lies ahead is an immense effort to revisit the underlying science of the existing regulations of radiation exposures. New evidence has been published, and most importantly, it is now recognized that many of these regulations--promulgated with the best of intentions--have been extraordinarily harmful to the public. In many cases, the harm has been exaggerated, and has created in the public policy arena the notion that the public is at great risk from the smallest sources of radiation. The national cost of compliance with these regulations has been enormous. To the extent that existing environmental regulations are not being moderated, they pose major economic threats to present and future industries involving nuclear materials and technology. These would include the pharmaceutical industries as well as those seeking U.S. isotope markets in separations, purification, labeling, and manufacturing of new radiopharmaceuticals for cancer therapy, diagnosis, pain mitigation, treatment of arthritis, and other new applications. For those who are not aware of the results of recent advances in radiopharmaceuticals, clinical trials have demonstrated an 80% remission rate in the treatment of b-cell lymphoma and leukemia. New isotopes and new isotope technology promise greater effectiveness in the treatment of cancer and other diseases. The regulatory problems and their enormous costs exist at all stages in nuclear medicine, from the manufacture of the radiopharmaceuticals to the disposal of low-level wastes in Ward Valley, California, for example. Access to these promising new technologies will be severely limited under the existing regulatory environment.

While the benefits of commonality seem obvious in terms of minimizing upfront development and long-term operations and maintenance costs, success in real, large-scale engineering systems used to support launch operations is relatively unknown. A broad literature review conducted for this paper did not yield a single paper specifically addressing the application of commonality for ground systems at any launch site in the United States or abroad. This paper provides a broad overview of the ground systems, captures historical and current application of commonality at the launch site, and offers suggestions for additional research to further develop commonality approaches.

  10. Governing the global commons with local institutions.

    PubMed

    Bodnar, Todd; Salathé, Marcel

    2012-01-01

    Most problems faced by modern human society have two characteristics in common--they are tragedy-of-the-commons type of problems, and they are global problems. Tragedy-of-the-commons type of problems are those where a commonly shared resource is overexploited by free riders at the expense of everyone sharing the resource. The exploitation of global resources such as clean air and water, political stability and peace, etc. underlies many of the most pressing human problems. Punishment of free riding behavior is one of the most frequently used strategies to combat the problem, but the spatial reach of sanctioning institutions is often more limited than the spatial effects of overexploitation. Here, we analyze a general game theoretical model to assess under what circumstances sanctioning institutions with limited reach can maintain the larger commons. We find that the effect of the spatial reach has a strong effect on whether and how the commons can be maintained, and that the transitions between those outcomes are characterized by phase transitions. The latter indicates that a small change in the reach of sanctioning systems can profoundly change the way the global commons can be managed. PMID:22509269

  1. A common-view disciplined oscillator

    SciTech Connect

    Lombardi, Michael A.; Dahlen, Aaron P.

    2010-05-15

    This paper describes a common-view disciplined oscillator (CVDO) that locks to a reference time scale through the use of common-view global positioning system (GPS) satellite measurements. The CVDO employs a proportional-integral-derivative controller that obtains near real-time common-view GPS measurements from the internet and provides steering corrections to a local oscillator. A CVDO can be locked to any time scale that makes real-time common-view data available and can serve as a high-accuracy, self-calibrating frequency and time standard. Measurement results are presented where a CVDO is locked to UTC(NIST), the coordinated universal time scale maintained at the National Institute of Standards and Technology in Boulder, Colorado.

  2. Phenotyping common beans for adaptation to drought

    Beebe, Stephen E.; Rao, Idupulapati M.; Blair, Matthew W.; Acosta-Gallegos, Jorge A.

    2013-01-01

    Common beans (Phaseolus vulgaris L.) originated in the New World and are the grain legume of greatest production for direct human consumption. Common bean production is subject to frequent droughts in highland Mexico, in the Pacific coast of Central America, in northeast Brazil, and in eastern and southern Africa from Ethiopia to South Africa. This article reviews efforts to improve common bean for drought tolerance, referring to genetic diversity for drought response, the physiology of drought tolerance mechanisms, and breeding strategies. Different races of common bean respond differently to drought, with race Durango of highland Mexico being a major source of genes. Sister species of P. vulgaris likewise have unique traits, especially P. acutifolius which is well adapted to dryland conditions. Diverse sources of tolerance may have different mechanisms of plant response, implying the need for different methods of phenotyping to recognize the relevant traits. Practical considerations of field management are discussed including: trial planning; water management; and field preparation. PMID:23507928

    2010-01-01

    Aggregate nuclear plant failure data is used to produce generic common-cause factors that are specifically for use in the common-cause failure models of NUREG/CR-5485. Furthermore, the models presented in NUREG/CR-5485 are specifically designed to incorporate two significantly distinct assumptions about the methods of surveillance testing from whence this aggregate failure data came. What are the implications of using these NUREG generic factors to model the common-cause failures of aerospace systems? Herein, the implications of using the NUREG generic factors in the modeling of aerospace systems are investigated in detail and strong recommendations for modeling the common-cause failures of aerospace systems are given.

  11. Consistency, common morality, and reflective equilibrium.

    PubMed

    Brand-Ballard, Jeffrey

    2003-09-01

    Biomedical ethicists often assume that common morality constitutes a largely consistent normative system. This premise is not taken for granted in general normative ethics. This paper entertains the possibility of inconsistency within common morality and explores methodological implications. Assuming common morality to be inconsistent casts new light on the debate between principlists and descriptivists. One can view the two approaches as complementary attempts to evade or transcend that inconsistency. If common morality proves to be inconsistent, then principlists might have reason to prefer a less pluralist theory, thereby moving closer to descriptivism. Descriptivists, by contrast, might want to qualify their claim to accommodate all of people's basic moral convictions. Finally, both camps might wish to adopt a more revisionist posture, accepting that an adequate ethical theory occasionally will contradict some of people's deepest moral convictions. Proper application of the method of reflective equilibrium, to which both descriptivists and principlists claim allegiance, may entail greater openness to revisionism than either camp admits.

    2001-09-01

    We describe Onchocerca dewittei japonica n. subsp. from the Japanese wild boar, Sus scrofa leucomystax, in Oita, Kyushu Island, where all seven animals examined were found to be infected. This study began with efforts to identify the causative species in a recent case of zoonotic onchocerciasis. Compared with Onchocerca dewittei dewittei from Sus scrofa jubatus in Malaysia, which was reexamined here, our new subspecies has much greater space between the ridges on the females. In addition, its microfilariae (from uteri) are shorter (192-210 microns compared with 228-247 microns), and only the posterior third of the microfilarial body is coiled, instead of the entire body. The Onchocerca species parasitic in suids (these two subspecies and O. ramachandrini from the warthog in the Ethiopian region) form a group sharing several characters. Among the most unusual characters are the body swellings (a specialized apparatus for mating, known in only a few other genera). In addition, longitudinal cuticular crests were found on males of both subspecies from wild boar and on females of O. ramachandrini. PMID:11584751

  18. A common language for computer security incidents

    SciTech Connect

    John D. Howard; Thomas A Longstaff

    1998-10-01

    Much of the computer security information regularly gathered and disseminated by individuals and organizations cannot currently be combined or compared because a common language has yet to emerge in the field of computer security. A common language consists of terms and taxonomies (principles of classification) which enable the gathering, exchange and comparison of information. This paper presents the results of a project to develop such a common language for computer security incidents. This project results from cooperation between the Security and Networking Research Group at the Sandia National Laboratories, Livermore, CA, and the CERT{reg_sign} Coordination Center at Carnegie Mellon University, Pittsburgh, PA. This Common Language Project was not an effort to develop a comprehensive dictionary of terms used in the field of computer security. Instead, the authors developed a minimum set of high-level terms, along with a structure indicating their relationship (a taxonomy), which can be used to classify and understand computer security incident information. They hope these high-level terms and their structure will gain wide acceptance, be useful, and most importantly, enable the exchange and comparison of computer security incident information. They anticipate, however, that individuals and organizations will continue to use their own terms, which may be more specific both in meaning and use. They designed the common language to enable these lower-level terms to be classified within the common language structure.

  19. Cutaneous Manifestations of Common Liver Diseases

    PubMed Central

    Dogra, Sunil; Jindal, Rashmi

    2012-01-01

    Skin functions as a window to our overall health and a number of systemic diseases result in various cutaneous changes. Knowledge of these manifestations helps in suspecting an underlying systemic illness. Cutaneous abnormalities are quite common in patients with liver diseases and this article aims to focus on these dermatoses. Cutaneous manifestations seen in patients with liver disease though common are nonspecific. They can also be seen in patients without liver diseases and generally do not indicate about a specific underlying hepatic disorder. The presence of a constellation of signs and symptoms is more useful in pointing toward an underlying hepatobiliary condition. The commonest symptom in patients with liver disease is pruritus which is often protracted and disabling. Other common features include spider angiomas, palmar erythema, paper money skin, xanthelasmas, pigmentary changes, and nutritional deficiencies. In this article, first the common cutaneous manifestations that may be associated with liver disorders are discussed and then common liver diseases with their specific cutaneous findings are discussed. Cutaneous abnormalities may be the first clue to the underlying liver disease. Identifying them is crucial for early diagnosis and better management. PMID:25755383

  20. Validating common reference intervals in routine laboratories.

    PubMed

    Jones, Graham Ross Dallas

    2014-05-15

    Common reference intervals for numerical pathology tests have been proposed for many years as an improvement over the common situation where individual laboratories establish or select and validate their own intervals. However it is important that any intervals that are developed for common use are themselves validated for use in individual laboratories. There are three main aspects to consider, the appropriateness of the interval, methodological factors and population factors. Techniques for assessing method biases are reasonably straightforward with the use of shared samples and appropriate external quality assurance schemes. Validating the local population, which also encompasses the laboratory's method, can be done using a number of healthy subjects, the more the better, or by various "data mining" techniques using the results of tests performed on routine patients. In any of these methods there is the need to consider the selection of subjects, the statistical approach and the acceptance criteria. Only if a proposed common reference interval can be shown to be appropriate in routine laboratories can it become widely adopted and become truly "common". PMID:24144864

  1. GPS common-view time transfer

    NASA Technical Reports Server (NTRS)

    Lewandowski, W.

    1994-01-01

    The introduction of the GPS common-view method at the beginning of the 1980's led to an immediate and dramatic improvement of international time comparisons. Since then, further progress brought the precision and accuracy of GPS common-view intercontinental time transfer from tens of nanoseconds to a few nanoseconds, even with SA activated. This achievement was made possible by the use of the following: ultra-precise ground antenna coordinates, post-processed precise ephemerides, double-frequency measurements of ionosphere, and appropriate international coordination and standardization. This paper reviews developments and applications of the GPS common-view method during the last decade and comments on possible future improvements whose objective is to attain sub-nanosecond uncertainty.

  2. Secondary Syphilis: Uncommon Manifestations a Common Disease

    1984-01-01

    Reports of cases of primary and secondary syphilis are increasing in the United States, particularly in urban areas and among homosexual men. While primary syphilis poses little diagnostic difficulty, many physicians are unfamiliar with the multisystem nature of secondary lues. Patients who have secondary syphilis commonly present with systemic signs, skin rash, mucous membrane lesions and generalized adenopathy. Less commonly, secondary syphilis may occur as acute meningitis, sensorineural hearing loss, iritis, anterior uveitis, optic neuritis, Bell's palsy, gastropathy, proctitis, hepatitis, pulmonary infiltration, nephrotic syndrome, glomerulonephritis, periostitis, tenosynovitis and polyarthritis. The diagnosis of secondary syphilis is easily confirmed. Its various manifestations are readily treated with penicillin and, if treated early, are entirely reversible. Two recent cases of secondary syphilis, one presenting as nephrotic syndrome and one as chorioretinitis and ptosis, illustrate the usual and unusual features of this common infection.

    A review and synthesis of existing information were used to develop riverine and lacustrine habitat models for common shiner (Notropis cornutus). The models are scaled to produce an index of habitat suitability between 0 (unsuitable habitat) to 1 (optimally suitable habitat) for the northeastern range of the common shiner in North America. Habitat suitability indexes (HSI's) are designed for use with the habitat evaluation procedures developed by the U.S. Fish and Wildlife Service. Also included are discussions of Suitability Index (SI) curves as used in the Instream Flow Incremental Methodology (IFIM) and SI curves available for an IFIM analysis of smallmouth bass habitat.

    2015-01-01

    The aim of this study was to evaluate genetic divergence in the 'Carioca' (beige with brown stripes) common bean cultivar used by different institutions and in 16 other common bean cultivars used in the Rede Cooperativa de Pesquisa de Feijão (Cooperative Network of Common Bean Research), by using simple sequence repeats associated with agronomic traits that are highly distributed in the common bean genome. We evaluated 22 polymorphic loci using bulks containing DNA from 30 plants. There was genetic divergence among the Carioca cultivar provided by the institutions. Nevertheless, there was lower divergence among them than among the other cultivars. The cultivar used by Instituto Agronômico do Paraná was the most divergent in relation to the Carioca samples. The least divergence was observed among the samples used by Universidade Federal de Lavras and by Embrapa Arroz e Feijão. Of all the cultivars, 'CNFP 10104' and 'BRSMG Realce' showed the greatest dissimilarity. The cultivars were separated in two groups of greatest similarity using the Structure software. Genetic variation among cultivars was greater than the variation within or between the groups formed. This fact, together with the high estimate of heterozygosity observed and the genetic divergence of the samples of the Carioca cultivar in relation to the original provided by Instituto Agronômico de Campinas, indicates a mixture of cultivars. The high divergence among cultivars provides potential for the utilization of this genetic variability in plant breeding. PMID:26400359

    1994-07-01

    Lately, toxic effects of some heavy metals (Pb, Cd) as well as desirable ones of some others (Ni, Mn, Zn) have been a field of thorough investigation. The main way of human body fortification in metals is through foodchain depending on the kind and quantity of the consumed food, according to dietary habits. The purpose of this study is the calculation of metals daily intake through common foodstuff of Greek inhabitants. The calculation is based on results from quantitative analysis of Pb, Cd, Ni, Mn, and Zn in common foodstuff from the market of the city of Thessaloniki. The daily food consumption data is derived from three sources: (a) answers to a questionnaire distributed to families of the city of Thessaloniki, (b) nutrition data provided by the Agricultural Bank of Greece and (c) nutrition data according to international bibliography.

  11. Plasticity facilitates sustainable growth in the commons

    PubMed Central

    Cavaliere, Matteo; Poyatos, Juan F.

    2013-01-01

    In the commons, communities whose growth depends on public good, individuals often rely on surprisingly simple strategies, or heuristics, to decide whether to contribute to the shared resource (at risk of exploitation by free-riders). Although this appears a limitation, we show here how four heuristics lead to sustainable growth when coupled to specific ecological constraints. The two simplest ones—contribute permanently or switch stochastically between contributing or not—are first shown to bring sustainability when the public good efficiently promotes growth. If efficiency declines and the commons is structured in small groups, the most effective strategy resides in contributing only when a majority of individuals are also contributors. In contrast, when group size becomes large, the most effective behaviour follows a minimal-effort rule: contribute only when it is strictly necessary. Both plastic strategies are observed in natural scenarios across scales that present them as relevant social motifs for the sustainable management of public goods. PMID:23365195

    Hand injuries are among the most frequent accidents seen in sports medicine. All too commonly they are considered trivial since the athlete may continue to participate actively and neglect his injury. The consequent delay in diagnosis and proper treatment may result in long-standing or even permanent disability. This paper describes the more commonly encountered hand injuries, their diagnosis and their optimal treatment. Included are soft-tissue injuries, ligamentous injuries, fractures and tendon avulsions. The basic principles applicable to skeletal and soft-tissue trauma of the hand, which physicians at all levels of sports medicine may encounter, are stressed.

    The pediatric health care provider is often faced with myriad decisions related to the use of infant formula. This article compares human milk to cow's milk. It addresses the composition, classification, and use of some of the most common infant formulas manufactured for use with the term infant in the outpatient setting. Common clinical situations are discussed, including the role for low-iron, goat's milk, and follow-up formulas, and formula use for the infant with diarrhea, colic, and atopic disease. The article highlights the poor quality of research and the lack of definitive answers available to the clinician when managing the infant with atopic disease. It concludes with a review of practical aspects of infant formula feeding for use in client education and management, including guidelines for formula preparation, calculating necessary formula intake, frequency, and quantity of infant feedings, and provisions of the WIC program.

    PubMed

    O'Connor, Nina R; McLaughlin, Maura R; Ham, Peter

    2008-01-01

    Rashes are extremely common in newborns and can be a significant source of parental concern. Although most rashes are transient and benign, some require additional work-up. Erythema toxicum neonatorum, acne neonatorum, and transient neonatal pustular melanosis are transient vesiculopustular rashes that can be diagnosed clinically based on their distinctive appearances. Infants with unusual presentations or signs of systemic illness should be evaluated for Candida, viral, and bacterial infections. Milia and miliaria result from immaturity of skin structures. Miliaria rubra (also known as heat rash) usually improves after cooling measures are taken. Seborrheic dermatitis is extremely common and should be distinguished from atopic dermatitis. Parental reassurance and observation is usually sufficient, but tar-containing shampoo, topical ketoconazole, or mild topical steroids may be needed to treat severe or persistent cases.

    Wes Fountain, C.; Jennings, Jeanne; McKie, Cheryl K.; Oakman, Patrice; Fetterolf, Monty L.

    1997-02-01

    Viscosity experiments using Ostwald-type gravity flow viscometers are not new to the physical chemistry laboratory. Several physical chemistry laboratory texts (1 - 3) contain at least one experiment studying polymer solutions or other well-defined systems. Several recently published articles (4 - 8) indicated the continued interest in using viscosity measurements in the teaching lab to illustrate molecular interpretation of bulk phenomena. Most of these discussions and teaching experiments are designed around an extensive theory of viscous flow and models of molecular shape that allow a full data interpretation to be attempted. This approach to viscosity experiments may not be appropriate for all teaching situations (e.g., high schools, general chemistry labs, and nonmajor physical chemistry labs). A viscosity experiment is presented here that is designed around common seed and vegetable oils. With the importance of viscosity to foodstuffs (9) and the importance of fatty acids to nutrition (10), an experiment using these common, recognizable oils has broad appeal.

  16. The Case for Common Reference Intervals

    PubMed Central

    Jones, Graham RD; Barker, Antony; Tate, Jill; Lim, Chen-Fee; Robertson, Ken

    2004-01-01

    The current paradigm for pathology reference intervals is for each laboratory to determine its own interval for use with each test offered by the laboratory. It is our contention that this approach does not best serve the medical community, especially at a time when electronic databases of health information are being expanded and integrated. We also believe that this approach is not performed well in many laboratories and is excessively expensive in practice. In contrast, we believe that the preferable option is to develop and apply common reference intervals throughout Australia and New Zealand, together with common reporting formats and assay standardisation wherever this is possible. We are aware that these are neither trivial nor simple issues, however we believe that failure to achieve this goal where technically possible will be a failure of the pathology profession to meet the challenges of the modern health community.

  17. Commonality analysis as a knowledge acquisition problem

    NASA Technical Reports Server (NTRS)

    Yeager, Dorian P.

    1987-01-01

    Commonality analysis is a systematic attempt to reduce costs in a large scale engineering project by discontinuing development of certain components during the design phase. Each discontinued component is replaced by another component that has sufficient functionality to be considered an appropriate substitute. The replacement strategy is driven by economic considerations. The System Commonality Analysis Tool (SCAT) is based on an oversimplified model of the problem and incorporates no knowledge acquisition component. In fact, the process of arriving at a compromise between functionality and economy is quite complex, with many opportunities for the application of expert knowledge. Such knowledge is of two types: general knowledge expressible as heuristics or mathematical laws potentially applicable to any set of components, and specific knowledge about the way in which elements of a given set of components interrelate. Examples of both types of knowledge are presented, and a framework is proposed for integrating the knowledge into a more general and useable tool.

    2015-08-01

    We introduce and explore a method for inferring hidden geometric coordinates of nodes in complex networks based on the number of common neighbors between the nodes. We compare this approach to the HyperMap method, which is based only on the connections (and disconnections) between the nodes, i.e., on the links that the nodes have (or do not have). We find that for high degree nodes, the common-neighbors approach yields a more accurate inference than the link-based method, unless heuristic periodic adjustments (or "correction steps") are used in the latter. The common-neighbors approach is computationally intensive, requiring O(t4) running time to map a network of t nodes, versus O(t3) in the link-based method. But we also develop a hybrid method with O(t3) running time, which combines the common-neighbors and link-based approaches, and we explore a heuristic that reduces its running time further to O(t2), without significant reduction in the mapping accuracy. We apply this method to the autonomous systems (ASs) Internet, and we reveal how soft communities of ASs evolve over time in the similarity space. We further demonstrate the method's predictive power by forecasting future links between ASs. Taken altogether, our results advance our understanding of how to efficiently and accurately map real networks to their latent geometric spaces, which is an important necessary step toward understanding the laws that govern the dynamics of nodes in these spaces, and the fine-grained dynamics of network connections.

  5. The GPM Common Calibrated Brightness Temperature Product

    The Global Precipitation Measurement (GPM) project will provide a core satellite carrying the GPM Microwave Imager (GMI) and will use microwave observations from a constellation of other satellites. Each partner with a satellite in the constellation will have a calibration that meets their own requirements and will decide on the format to archive their brightness temperature (Tb) record in GPM. However, GPM multi-sensor precipitation algorithms need to input intercalibrated Tb's in order to avoid differences among sensors introducing artifacts into the longer term climate record of precipitation. The GPM Common Calibrated Brightness Temperature Product is intended to address this problem by providing intercalibrated Tb data, called "Tc" data, where the "c" stands for common. The precipitation algorithms require a Tc file format that is both generic and flexible enough to accommodate the different passive microwave instruments. The format will provide detailed information on the processing history in order to allow future researchers to have a record of what was done. The format will be simple, including the main items of scan time, latitude, longitude, and Tc. It will also provide spacecraft orientation, spacecraft location, orbit, and instrument scan type (cross-track or conical). Another simplification is to store data in real numbers, avoiding the ambiguity of scaled data. Finally, units and descriptions will be provided in the product. The format is built on the concept of a swath, which is a series of scans that have common geolocation and common scan geometry. Scan geometry includes pixels per scan, sensor orientation, scan type, and incidence angles. The Tc algorithm and data format are being tested using the pre-GPM Precipitation Processing System (PPS) software to generate formats and 1/0 routines. In the test, data from SSM/I, TMI, AMSR-E, and WindSat are being processed and written as Tc products.

  6. Common themes in microbial pathogenicity revisited.

    Bacterial pathogens employ a number of genetic strategies to cause infection and, occasionally, disease in their hosts. Many of these virulence factors and their regulatory elements can be divided into a smaller number of groups based on the conservation of similar mechanisms. These common themes are found throughout bacterial virulence factors. For example, there are only a few general types of toxins, despite a large number of host targets. Similarly, there are only a few conserved ways to build the bacterial pilus and nonpilus adhesins used by pathogens to adhere to host substrates. Bacterial entry into host cells (invasion) is a complex mechanism. However, several common invasion themes exist in diverse microorganisms. Similarly, once inside a host cell, pathogens have a limited number of ways to ensure their survival, whether remaining within a host vacuole or by escaping into the cytoplasm. Avoidance of the host immune defenses is key to the success of a pathogen. Several common themes again are employed, including antigenic variation, camouflage by binding host molecules, and enzymatic degradation of host immune components. Most virulence factors are found on the bacterial surface or secreted into their immediate environment, yet virulence factors operate through a relatively small number of microbial secretion systems. The expression of bacterial pathogenicity is dependent upon complex regulatory circuits. However, pathogens use only a small number of biochemical families to express distinct functional factors at the appropriate time that causes infection. Finally, virulence factors maintained on mobile genetic elements and pathogenicity islands ensure that new strains of pathogens evolve constantly. Comprehension of these common themes in microbial pathogenicity is critical to the understanding and study of bacterial virulence mechanisms and to the development of new "anti-virulence" agents, which are so desperately needed to replace antibiotics.

    Explaining patterns of commonness and rarity is fundamental for understanding and managing biodiversity. Consequently, a key test of biodiversity theory has been how well ecological models reproduce empirical distributions of species abundances. However, ecological models with very different assumptions can predict similar species abundance distributions, whereas models with similar assumptions may generate very different predictions. This complicates inferring processes driving community structure from model fits to data. Here, we use an approximation that captures common features of "neutral" biodiversity models--which assume ecological equivalence of species--to test whether neutrality is consistent with patterns of commonness and rarity in the marine biosphere. We do this by analyzing 1,185 species abundance distributions from 14 marine ecosystems ranging from intertidal habitats to abyssal depths, and from the tropics to polar regions. Neutrality performs substantially worse than a classical nonneutral alternative: empirical data consistently show greater heterogeneity of species abundances than expected under neutrality. Poor performance of neutral theory is driven by its consistent inability to capture the dominance of the communities' most-abundant species. Previous tests showing poor performance of a neutral model for a particular system often have been followed by controversy about whether an alternative formulation of neutral theory could explain the data after all. However, our approach focuses on common features of neutral models, revealing discrepancies with a broad range of empirical abundance distributions. These findings highlight the need for biodiversity theory in which ecological differences among species, such as niche differences and demographic trade-offs, play a central role. PMID:24912168

    To identify genes that are commonly dysregulated in a murine model of acute promyelocytic leukemia (APL), we first defined gene expression patterns during normal murine myeloid development; serial gene expression profiling studies were performed with primary murine hematopoietic progenitors that were induced to undergo myeloid maturation in vitro with G-CSF. Many genes were reproducibly expressed in restricted developmental “windows,” suggesting a structured hierarchy of expression that is relevant for the induction of developmental fates and/or differentiated cell functions. We compared the normal myeloid developmental transcriptome with that of APL cells derived from mice expressing PML-RAR? under control of the murine cathepsin G locus. While many promyelocyte-specific genes were highly expressed in all APL samples, 116 genes were reproducibly dysregulated in many independent APL samples, including Fos, Jun, Egr1, Tnf, and Vcam1. However, this set of commonly dysregulated genes was expressed normally in preleukemic, early myeloid cells from the same mouse model, suggesting that dysregulation occurs as a “downstream” event during disease progression. These studies suggest that the genetic events that lead to APL progression may converge on common pathways that are important for leukemia pathogenesis. PMID:17008535

    The number of pods per common bean plant is a primary component of grain yield, which depends on the number of flowers produced and on the flower set. Thus, a larger number of flowers per plant would increase yield. Lines with inflorescences that had a large number of flowers compared to common bean plants now under cultivation were identified. We analyzed the genetic control of this trait and its association with grain yield. The cultivar BRSMG Talismã was crossed with 2 lines, L.59583 and L.59692, which have a large number of flowers. The F1, F2, and F3 generations were obtained. These generations were assessed together with the parents in a randomized block experimental design with 2 replications. The traits assessed included length of inflorescence, number of pods per inflorescence, number of pods per plant, number of grains per plant, 100-grain weight, and grain yield per plant. Mean genetic components and variance were estimated. The traits length of inflorescence and number of pods per inflorescence exhibited genetic control with predominance that showed an additive effect. In the 2 crosses, genetic control of grain yield and of its primary components showed that the allelic interaction of dominance was high. The wide variability in the traits assessed may be used to increase yield of the common bean plant by increasing the number of flowers on the plant. PMID:25501247

  10. Efficient heuristics for maximum common substructure search.

    2015-05-26

    Maximum common substructure search is a computationally hard optimization problem with diverse applications in the field of cheminformatics, including similarity search, lead optimization, molecule alignment, and clustering. Most of these applications have strict constraints on running time, so heuristic methods are often preferred. However, the development of an algorithm that is both fast enough and accurate enough for most practical purposes is still a challenge. Moreover, in some applications, the quality of a common substructure depends not only on its size but also on various topological features of the one-to-one atom correspondence it defines. Two state-of-the-art heuristic algorithms for finding maximum common substructures have been implemented at ChemAxon Ltd., and effective heuristics have been developed to improve both their efficiency and the relevance of the atom mappings they provide. The implementations have been thoroughly evaluated and compared with existing solutions (KCOMBU and Indigo). The heuristics have been found to greatly improve the performance and applicability of the algorithms. The purpose of this paper is to introduce the applied methods and present the experimental results. PMID:25865959

  11. Bald eagle predation on common loon egg

    The Common Loon (Gavia immer) must defend against many potential egg predators during incubation, including corvids, Herring Gulls (Larus argentatus), raccoons (Procyon lotor), striped skunk (Mephitis mephitis), fisher (Martes pennanti), and mink (Neovison vison) (McIntyre 1988, Evers 2004, McCann et al. 2005). Bald Eagles (Haliaeetus leucocephalus) have been documented as predators of both adult Common Loons and their chicks (Vliestra and Paruk 1997, Paruk et al. 1999, Erlandson et al. 2007, Piper et al. 2008). In Wisconsin, where nesting Bald Eagles are abundant (.1200 nesting pairs, .1 young/pair/year), field biologists observed four instances of eagle predation of eggs in loon nests during the period 2002–2004 (M. Meyer pers. comm.). In addition, four cases of eagle predation of incubating adult loons were inferred from evidence found at the loon nest (dozens of plucked adult loon feathers, no carcass remains) and/or loon leg, neck, and skull bones beneath two active eagle nests, including leg bones containing the bands of the nearby (,25 m) incubating adult loon. However, although loon egg predation has been associated with Bald Eagles, predation events have yet to be described in peer-reviewed literature. Here we describe a photographic observation of predation on a Common Loon egg by an immature Bald Eagle as captured by a nest surveillance video camera on Lake Umbagog, a large lake (32 km2) at Umbagog National Wildlife Refuge (UNWR) in Maine.

  4. Demography and the tragedy of the commons.

    PubMed

    Frank, S A

    2010-01-01

    Individual success in group-structured populations has two components. First, an individual gains by outcompeting its neighbours for local resources. Second, an individual's share of group success must be weighted by the total productivity of the group. The essence of sociality arises from the tension between selfish gains against neighbours and the associated loss that selfishness imposes by degrading the efficiency of the group. Without some force to modulate selfishness, the natural tendencies of self interest typically degrade group performance to the detriment of all. This is the tragedy of the commons. Kin selection provides the most widely discussed way in which the tragedy is overcome in biology. Kin selection arises from behavioural associations within groups caused either by genetical kinship or by other processes that correlate the behaviours of group members. Here, I emphasize demography as a second factor that may also modulate the tragedy of the commons and favour cooperative integration of groups. Each act of selfishness or cooperation in a group often influences group survival and fecundity over many subsequent generations. For example, a cooperative act early in the growth cycle of a colony may enhance the future size and survival of the colony. This time-dependent benefit can greatly increase the degree of cooperation favoured by natural selection, providing another way in which to overcome the tragedy of the commons and enhance the integration of group behaviour. I conclude that analyses of sociality must account for both the behavioural associations of kin selection theory and the demographic consequences of life history theory. PMID:19912449

    The goal of the common coil magnet R&D program at Brookhaven National Laboratory (BNL) is to develop a 12.5 T, 40 mm aperture dipole magnet using ''React and Wind Technology'' with High Temperature Superconductors (HTS) playing a major role. Due to its ''conductor friendly'' nature, the common coil design is attractive for building high field 2-in-1 dipoles with brittle materials such as HTS and Nb{sub 3}Sn. At the current rate of development, it is expected that a sufficient amount of HTS with the required performance would be available in a few years for building a short magnet. In the interim, the first generation dipoles will be built with Nb{sub 3}Sn superconductor. They will use a ''React and Wind'' technology similar to that used in HTS and will produce a 12.5 T central field in a 40 mm aperture. The Nb{sub 3}Sn coils and support structure of this magnet will become a part of the next generation hybrid magnet with inner coils made of HTS. To develop various aspects of the technology in a scientific and experimental manner, a 10-turn coil program has been started in parallel. The program allows a number of concepts to be evaluated with a rapid throughput in a cost-effective way. Three 10-turn Nb{sub 3}Sn coils have been built and one HTS coil is under construction. The initial test results of this ''React & Wind'' 10-turn coil program are presented. It is also shown that a common coil magnet design can produce a field quality that is as good as a conventional cosine theta design.

    The polar regions are changing rapidly with dramatic global effect. Wise management of resources, improved decision support, and effective international cooperation on resource and geopolitical issues require deeper understanding and better prediction of these changes. Unfortunately, polar data and information remain scattered, scarce, and sporadic. Inspired by the Antarctic Treaty of 1959 that established the Antarctic as a global commons to be used only for peaceful purposes and scientific research, we assert that data and information about the polar regions are themselves “public goods” that should be shared ethically and with minimal constraint. We therefore envision the Polar Information Commons (PIC) as an open, virtual repository for vital scientific data and information that would provide a shared, community-based cyber-infrastructure fostering innovation, improving scientific efficiency, and encouraging participation in polar research, education, planning, and management. The PIC will build on the legacy of the International Polar Year (IPY), providing a long-term framework for access to and preservation of both existing and future data and information about the polar regions. Rapid change demands rapid data access. The PIC system will enable scientists to quickly expose their data to the world and share them through open protocols on the Internet. A PIC digital label will alert users and data centers to new polar data and ensure that usage rights are clear. The PIC will utilize the Science Commons Protocol for Implementing Open Access Data, which promotes open data access through the public domain coupled with community norms of practice to ensure use of data in a fair and equitable manner. A set of PIC norms is currently being developed in consultation with key polar data organizations and other stakeholders. We welcome inputs from the broad science community as we further develop and refine the PIC approach and move ahead with implementation.

  9. Common Criteria Based Security Scenario Verification

    NASA Astrophysics Data System (ADS)

    Ohnishi, Atsushi

    Software is required to comply with the laws and standards of software security. However, stakeholders with less concern regarding security can neither describe the behaviour of the system with regard to security nor validate the system’s behaviour when the security function conflicts with usability. Scenarios or use-case specifications are common in requirements elicitation and are useful to analyze the usability of the system from a behavioural point of view. In this paper, the authors propose both (1) a scenario language based on a simple case grammar and (2) a method to verify a scenario with rules based on security evaluation criteria.

    2015-11-01

    Common variable immunodeficiency (CVID) refers to a grouping of antibody deficiencies that lack a more specific genetic or phenotypic classification. It is the immunodeficiency classification with the greatest number of constituents, likely because of the numerous ways in which antibody production can be impaired and the frequency in which antibody production becomes impaired in human beings. CVID comprises a heterogeneous group of rare diseases. Consequently, CVID presents a significant challenge for researchers and clinicians. Despite these difficulties, both our understanding of and ability to manage this grouping of complex immune diseases has advanced significantly over the past 60 years. PMID:26454311

    Common hippopotami (Hippopotamus amphibius) introduced to Colombia in the 80s have since spread into livestock areas. Measures such as breeding control are needed to prevent further uncontrolled population growth. A young female hippopotamus was moved to a university veterinary hospital and anesthetized. Laparoscopic ovariectomy was attempted, but because of the difficulty of inserting the trocars in an apparently lax peritoneum, lateral laparotomy was performed. Both ovaries were transected with the use of an ultrasonic hemostatic device and clamping. Patient recovery was completely successful and the wound healed with few complications. To the authors' knowledge, this is the first report describing a successful ovariectomy in a hippopotamus. PMID:26056898

    The cognitive architecture of concept is a specific structure consisting of the concept core, concept periphery, the semantic frame as the meaning and the sense of the concept, and the relations among all components of this structure. The model of the cognitive architecture of scientific and common concepts is a conceptual meta-model built upon Vygotsky's concept theory, Fillmore's semantic frame, semantic triangle, on widespread ideas of the structuring of conceptual systems, and the Hestenes' Modeling Theory. The method of semantic mapping of concepts flowing from the model is designed.

    There are several pitfalls and problems associated with the successful design of a new gear transmission. A new design will require the knowledge and experience of several technical areas of engineering. Most of the pitfalls and problems associated with a new design are related to an inadequate evaluation of several areas, such as, the lubrication and cooling requirements, complete static and dynamic load analysis, evaluation of materials and heat treatment and the latest manufacturing technology. Some of the common problems of the gear design process are discussed with recommendations made for avoiding these conditions.

    The prevalence of antibodies to Neospora caninum was examined in six wild Artiodactyla species, and in five wild Carnivora species from Kenya. Blood sera (104 wild ungulates from Marula Estates (MEs), and 31 wild carnivores from Masai-Mara reserve and from other wildlife areas in northern and Southern Kenya), were screened using a Neospora agglutination test (NAT), with a twofold dilution (1:40-1:320 titres). Presence of NAT antibodies to N. caninun is reported here for the first time in zebra (Equus burchelli), eland (Taurotragus oryx), African buffalo (Syncerus caffer), Thompson gazelle (Gazella thompsoni), impala (Aepyceros melampus), warthog (Phacochoerus aethiopicus), spotted hyena (Crocuta crocuta) and in free-ranging cheetah (Acinonyx jubatus). At 1:80 dilution, prevalence was 61.5% in eland, 58.5% in zebra, 19.2% in Thompson gazelle, 33.3% in warthog, 50% in African buffalo, 30% in lion (Panthera leo), 20% in cheetah, and 33.3% in spotted hyena. Antibodies up to 1:320 titre were detected in eland (38.4%), zebra (19.5%), Thompson gazelle (3.8%) and lion (5%). Amongst herbivores, sero-prevalence was significantly (P<0.05) higher, at all dilutions, in "grazer/digger" species (e.g. eland and zebra) than in non-"grazer/digger" species (e.g. impala and Thompson gazelle). No antibodies to N. caninum were found in two leopards (Panthera pardus) and one serval (Felis serval). Our results indicates a steady presence of N. caninum in wild mammals from Kenya. The hypothesis of a sylvatic cycle of N. caninum could be suggested, but more data are needed to verify the hypothesis, as to evaluate the role of N. caninum infection on the dynamics of wild animals population in the study area.

    The Robotic Collaborative Technology Alliance (RCTA) seeks to provide adaptive robot capabilities which move beyond traditional metric algorithms to include cognitive capabilities. Key to this effort is the Common World Model, which moves beyond the state-of-the-art by representing the world using metric, semantic, and symbolic information. It joins these layers of information to define objects in the world. These objects may be reasoned upon jointly using traditional geometric, symbolic cognitive algorithms and new computational nodes formed by the combination of these disciplines. The Common World Model must understand how these objects relate to each other. Our world model includes the concept of Self-Information about the robot. By encoding current capability, component status, task execution state, and histories we track information which enables the robot to reason and adapt its performance using Meta-Cognition and Machine Learning principles. The world model includes models of how aspects of the environment behave, which enable prediction of future world states. To manage complexity, we adopted a phased implementation approach to the world model. We discuss the design of "Phase 1" of this world model, and interfaces by tracing perception data through the system from the source to the meta-cognitive layers provided by ACT-R and SS-RICS. We close with lessons learned from implementation and how the design relates to Open Architecture.

    Produced waters from oil and gas drilling operations are typically very saline, and these may cause acute toxicity to marine organisms due to osmotic imbalances as well as to an excess or deficiency of specific common ions. In order to better understand the relationship between toxicity and ion concentration, laboratory toxicity tests were conducted using mysid shrimp (Mysidopsis bahia), sheepshead minnow (Cyprinodon variegatus), and inland silverside (Menidia beryllina). For each species the ionic concentration of standard laboratory water was proportionally increased or decreased to produce test solutions with a range of salinities. Organisms were exposed for 48 hours. Individual ions (sodium, potassium, calcium, magnetsium, strontium, chloride, bromide, sulfate, bicarbonate, and borate) were also manipulated to examine individual ion toxicity. The three test species differ in their tolerance of salinity. Mysid shrimp show a marked decrease in survival at salinities less than approximately 5 ppt. Both fish species tolerated low salinity water, however, silversides were less tolerant of saline waters (salinity greater than 40 ppt). There were also significant differences in the responses of the organisms to different ions. The results show that the salinity of the test solution may play an important role in the responses of the organisms to the produced water effluent. Predictable toxicity/ion relationships developed in this study can be used to estimate whether toxicity in a produced water is a result of common ions, salinity, or some other unknown toxicant.

  19. Food Allergy: Common Causes, Diagnosis, and Treatment.

    2015-10-01

    Food allergy is a growing concern, and recognition of symptoms, knowledge of common food allergens, and management of reactions are important for patients and practitioners. Symptoms of a classic IgE-mediated food allergy vary in severity and can include any combination of laryngeal edema, wheezing, nausea, vomiting, diarrhea, urticaria, angioedema, and hypotension. Many foods can induce an allergic reaction, but the most commonly implicated foods include cow's milk, egg, peanut, tree nut, soy, wheat, fish, and shellfish. Milk and egg allergy generally develop and are outgrown in childhood. Peanut and tree nut allergy can occur during childhood or adulthood, are less likely to be outgrown, and tend to cause more fatal reactions. Given the possibility of life-threatening reactions, it is important to recognize the potential for cross-reactivity among food groups. Diagnosis of food allergy includes skin prick testing, specific serum IgE testing, and oral food challenges. Management is centered on avoidance of allergenic and cross-reacting foods and early recognition and immediate treatment of reactions. Treatment protocols to desensitize patients to food are currently under investigation. PMID:26434966

    Iran is suffering from the 2nd most severe addiction to opioids in the world. While the explanation of this enormous drug problem is refutably related to drug trafficking, the drug dilemma also illustrates the chain reaction of the imposed war with Iraq in 1980 - 88; the problems of poverty, unemployment, urbanization, homelessness, adultery, family crises, divorce, domestic violence, and runaway children. Although opium addiction often linked to these factors, drug use is common among all social classes. It seems that a positive traditional attitude is another reason for widespread raw opium use in this country. A survey in Iranian literature reveals that famous Iranian poets, who have a substantial contribution on cultural attitude formation of Iranian population, have used the phrase “Teriac” (raw opium) as a means of “antidote” a substance that treats every disease. It seems that a concrete deduction from the literature has been leaden to a positive attitude towards opium consumption in Persian culture. Recent research also supports this idea. Many patients use raw opium as a pain killer or for treating hyperlipidemia, hypertension, diabetes and other chronic diseases; most of them had started the use after developing the disease and the remaining had increased the consumption after developing the disease. Regarding this superstitious common belief, drug control headquarters should focus on education and correction of the faulty unhealthy attitude toward opium consumption. PMID:26288642

  2. Auditory verbal hallucinations in schizophrenia and post-traumatic stress disorder: common phenomenology, common cause, common interventions?

    2015-01-01

    Auditory verbal hallucinations (AVH: ‘hearing voices’) are found in both schizophrenia and post-traumatic stress disorder (PTSD). In this paper we first demonstrate that AVH in these two diagnoses share a qualitatively similar phenomenology. We then show that the presence of AVH in schizophrenia is often associated with earlier exposure to traumatic/emotionally overwhelming events, as it is by definition in PTSD. We next argue that the content of AVH relates to earlier traumatic events in a similar way in both PTSD and schizophrenia, most commonly having direct or indirect thematic links to emotionally overwhelming events, rather than being direct re-experiencing. We then propose, following cognitive models of PTSD, that the reconstructive nature of memory may be able to account for the nature of these associations between trauma and AVH content, as may threat-hypervigilance and the individual’s personal goals. We conclude that a notable subset of people diagnosed with schizophrenia with AVH are having phenomenologically and aetiologically identical experiences to PTSD patients who hear voices. As such we propose that the iron curtain between AVH in PTSD (often termed ‘dissociative AVH’) and AVH in schizophrenia (so-called ‘psychotic AVH’) needs to be torn down, as these are often the same experience. One implication of this is that these trauma-related AVH require a common trans-diagnostic treatment strategy. Whilst antipsychotics are already increasingly being used to treat AVH in PTSD, we argue for the centrality of trauma-based interventions for trauma-based AVH in both PTSD and in people diagnosed with schizophrenia.

    The Atlantic coast of North America provides a sedimentary record of Common Era sea levels with the resolution to identify the mechanisms that cause spatial variability in sea-level rise. This coast has a small tidal range, improving the precision of sea-level reconstructions. Coastal subsidence (from glacial isostatic adjustment, GIA) creates accommodation space that is filled by salt-marsh peat and preserves accurate and precise sea-level indicators and abundant material for radiocarbon dating. In addition, the western North Atlantic Ocean is sensitive to spatial variability in sea-level change, because of static equilibrium effects from melting of the Greenland Ice Sheet, ocean circulation and wind-driven variability in the Gulf Stream and GIA induced land-level change from ongoing collapse of Laurentide forbuldge. We reveal three distinct patters in sea-level during the Common Era along the North American Atlantic coast, likely linked to wind-driven changes in the Gulf Stream: (1) Florida, sea level is essentially flat, with the record dominated by long-term geological processes; (2) North Carolina, sea level falls to a minimum near the beginning of the second millennium, climbing to an early Little Ice Age maximum in the fifteenth century, and then declining through most of the nineteenth century; and (3) New Jersey, a sea-level maximum around 900 CE, a sea-level minimum around 1500 CE, and a long-term sea-level rise through the second half of the second millennium. We combine the salt-marsh data from North American Atlantic coast with tide-gauge records and lower resolution proxies from the northern and southern hemispheres. We apply a noisy-input Gaussian process spatio-temporal modeling framework, which identifies a long-term falling global mean sea-level (GMSL), interrupted in the middle of the 19th century by an acceleration yielding a 20th century rate of rise extremely likely (probability P = 0:95) faster than any previous century in the Common Era.

    Multi-leader-common-follower games arise when modelling two or more competitive firms, the leaders, that commit to their decisions prior to another group of competitive firms, the followers, that react to the decisions made by the leaders. These problems lead in a natural way to equilibrium problems with equilibrium constraints (EPECs). We develop a characterization of the solution sets for these problems and examine a variety of nonlinear optimization and nonlinear complementarity formulations of EPECs. We distinguish two broad cases: problems where the leaders can cost-differentiate and problems with price-consistent followers. We demonstrate the practical viability of our approach by solving a range of medium-sized test problems.

    Light and cold extrasolar planets such as OGLE 2005-BLG-390Lb, a 5.5 Earth-mass planet detected via microlensing, could be frequent in the Galaxy according to some preliminary results from microlensing experiments. These planets can be frozen rocky- or ocean-planets, situated beyond the snow line and, therefore, beyond the habitable zone of their system. They can nonetheless host a layer of liquid water, heated by radiogenic energy, underneath an ice shell surface for billions of years, before freezing completely. These results suggest that oceans under ice, like those suspected to be present on icy moons in the Solar system, could be a common feature of cold low-mass extrasolar planets.

    The Common Message Logging (CMLOG) system is an object-oriented and distributed system that not only allows applications and systems to log data (messages) of any type into a centralized database but also lets applications view incoming messages in real-time or retrieve stored data from the database according to selection rules. It consists of a concurrent Unix server that handles incoming logging or searching messages, a Motif browser that can view incoming messages in real-time or display stored data in the database, a client daemon that buffers and sends logging messages to the server, and libraries that can be used by applications to send data to or retrieve data from the database via the server. This paper presents the design and implementation of the CMLOG system meanwhile it will also address the issue of integration of CMLOG into existing control systems.

    Intertrigo is inflammation of skinfolds caused by skin-on-skin friction. It is a common skin condition affecting opposing cutaneous or mucocutaneous surfaces. Intertrigo may present as diaper rash in children. The condition appears in natural and obesity-created body folds. The friction in these folds can lead to a variety of complications such as secondary bacterial or fungal infections. The usual approach to managing intertrigo is to minimize moisture and friction with absorptive powders such as cornstarch or with barrier creams. Patients should wear light, nonconstricting, and absorbent clothing and avoid wool and synthetic fibers. Physicians should educate patients about precautions with regard to heat, humidity, and outside activities. Physical exercise usually is desirable, but patients should shower afterward and dry intertriginous areas thoroughly. Wearing open-toed shoes can be beneficial for toe web intertrigo. Secondary bacterial and fungal infections should be treated with antiseptics, antibiotics, or antifungals, depending on the pathogens. PMID:16156342

    The timing method enables to search planets in extreme conditions, e.g. as companion to pulsars or as planets in post-common envelope binaries (PCEB). In both cases, the planetary systems have experience a dramatic evolution of the primary star.Eclipse time variations in PCEBs with white dwarfs and subdwarf-B stars as primaries have been interpreted as signatures from circumbinary planets and planetary systems. Several of these interpretations have been questioned later on, either due to dynamical instability of the proposed planetary systems or due to non-detection of the proposed companions. We will give an overview of our long-term monitoring of PCEB systems and the modelling in terms of Keplerian and Newtonian planetary orbits in order to assess the circumbinary planet scenario for these systems. We discuss the implications for the first-generation or second-generatoin planet scenario for these potential planets around these evolved stars.

    Advancing age is a major risk factor for cognitive impairment and dementia. Currently, there are no effective preventive strategies for cognitive decline. Since physicians have no drug therapies to offer, patients and families may turn to complementary and alternative medicine to preserve cognition. Dietary supplements are one of the most common forms of complementary and alternative medicine that patients use and although limited, evidence for their potential interactions with other treatments has been documented. Considering the insufficient evidence for their efficacy, potential for interaction with other therapies and costs to patients, physicians should be aware of the use of dietary supplements among their patients so that they can advise their patients on the potential benefits and harms.

    Common bacterial skin infections represent frequent disorders encountered in general practice and in dermatology as well. They encompass a series of infections affecting the epidermis, dermis, hypodermis and subcutaneous tissues. The two main bacteria involved in these processes are Streptococcus pyogenes and Staphylococcus aureus. The resulting infections show various clinical presentations. Their management must be adapted to their gravity and to the putative or proven nature of the causal microorganism. Searching for any skin ingress possibility and any favouring factor is always of importance in order to stimulate healing and avoid recurrences. Of note, skin possibly allows the ingress way for a secondary septicemic dissemination. Conversely, skin is possibly involved in tissue localisation of septicemia. PMID:23167160

    Postural quality during musical performance affects both musculoskeletal health and the quality of the performance. In this study we examined the posture of 100 students at a Higher Conservatory of Music in Spain. By analysing video tapes and photographs of the students while performing, a panel of experts extracted values of 11 variables reflecting aspects of overall postural quality or the postural quality of various parts of the body. The most common postural defects were identified, together with the situations in which they occur. It is concluded that most students incur in unphysiological postures during performance. It is hoped that use of the results of this study will help correct these errors. PMID:26118530

    Dark matter, baryonic matter, and dark energy have different properties but contribute comparable energy density to the present Universe. We point out that they may have a common origin. As the dark energy has a scale far lower than all known scales in particle physics but very close to neutrino masses, while the excess matter over antimatter in the baryonic sector is probably related to the neutrino-mass generation, we unify the origin of the dark and visible universe in a variant of the seesaw model. In our model (i) the dark matter relic density is a dark matter asymmetry emerged simultaneously with the baryon asymmetry from leptogenesis; (ii) the dark energy is due to a pseudo-Nambu-Goldstone-Boson associated with the neutrino-mass generation.

    Recent experiments have proved that the response to short laser pulses of common optical media, such as air or oxygen, can be described by focusing Kerr and higher order nonlinearities of alternating signs. Such media support the propagation of steady solitary waves. We argue by both numerical and analytical computations that the low-power fundamental bright solitons satisfy an equation of state which is similar to that of a degenerate gas of fermions at zero temperature. Considering, in particular, the propagation in both O{sub 2} and air, we also find that the high-power solutions behave like droplets of ordinary liquids. We then show how a grid of the fermionic light bubbles can be generated and forced to merge in a liquid droplet. This leads us to propose a set of experiments aimed at the production of both the fermionic and liquid phases of light, and at the demonstration of the transition from the former to the latter.

    Standard textbooks discuss parasitic disease according to specific organisms. In contrast, patients with parasitic infections present to physicians with a variety of clinical manifestations that may involve any of several organ systems and that often mimic nonparasitic diseases. A syndromic approach to the clinical situation may help the physician in considering the most important parasitic agents. Many parasitic infections can be acquired in temperate climates. While often considered tropical or exotic, other parasitic diseases are now seen more frequently in developed countries because of immigration and increased world travel. In this review the clinical syndromes associated with common parasitic diseases in North America are discussed, with an emphasis on risk factors and diagnosis of specific infections. PMID:4042057

    The negative ion photoelectron spectra of the following MALDI matrix molecules have been measured: 3-carboxypyridine (nicotinic acid), 2,5-dihydroxybenzoic acid (DHB), 3,5-dimethoxy-4-hydroxycinnamic acid (sinapinic acid), 2,6-dihydroxyacetophenone (DHAP), 3-(4-hydroxy-3-methoxyphenyl)-2-propenoic acid (ferulic acid), 3-hydroxy-2-pyridinecarboxylic acid (3HPA), and 2,6-pyridinedicarboxylic acid (dipicolinic acid). Adiabatic electron affinities and vertical detachment energies were extracted from these spectra and reported. In addition, electron affinities were calculated for DHAP, ferulic acid, dipicolinic acid and sinapinic acid. Photoelectron spectra were also measured for the dimer anions of DHB and nicotinic acid and for the fragment anion in which alpha-cyano-cinnamic acid had lost a CO2 unit. Together, these results augment the database of presently available electrophilic data on common matrix molecules along with some of their dimers and fragments.

    2006-01-01

    Raynaud's phenomenon (RP) is caused by a reversible spasm of the smallest arteries and the arterioles of the fingers and toes. Two forms of RP have been described: primary and secondary. Secondary RP is often present in patients with rheumatic diseases. This review presents the characteristics of the clinical pattern, the immunological profile and the capillaroscopic pattern in patients with primary and secondary RP in common rheumatic diseases. Attention is paid to standard examinations usually used in RP patients. Primary RP appears to be more common in women beginning usually at puberty. This disorder is caused by vasospasm; no abnormalities of the endothelium are observed. Primary RP shows benign progression. Laboratory tests - erythrocyte sedimentation rate (ESR) and antinuclear antibody test (ANA) - are normal. Capillaroscopy is normal too. Secondary RP tends to begin later in life. Of the rheumatic diseases, scleroderma is the one that is the most often associated with RP (in 90-95% of all cases). The pathogenesis of secondary RP in scleroderma is explained with abnormalities of the endothelium through different mechanisms. Motor ulcerations are frequently observed. Anticentromeric and antitopoizomeric antibodies get positive. Capillaroscopy appears to be very important for the early diagnosis and prognosis of scleroderma. The capillaroscopic pattern is abnormal - enlarged capillaries, hemorrhages and avascular areas are observed. Part of the patients with systemic lupus erythematosus, Sjogren's syndrome and polymyositis / dermatomyositis develops secondary RP and it usually shows benign progression. RP is the main symptom in mixed connective tissue disease and trophic abnormalities of the fingers are frequently observed. Elevated anti-U1-RNP antibody titers and an abnormal capillaroscopic pattern are specific for the condition. In older patients isolated RP may represent a paraneoplastic manifestation. RP is frequently found in the rheumatologic practice. The differentiation of the primary form from the secondary one is essential because of the differences concerning the heaviness of the disorder, the prognosis and the therapeutic approach.

  1. Common occupational classification system - revision 3

    Stahlman, E.J.; Lewis, R.E.

    1996-05-01

    Workforce planning has become an increasing concern within the DOE community as the Office of Environmental Restoration and Waste Management (ER/WM or EM) seeks to consolidate and refocus its activities and the Office of Defense Programs (DP) closes production sites. Attempts to manage the growth and skills mix of the EM workforce while retaining the critical skills of the DP workforce have been difficult due to the lack of a consistent set of occupational titles and definitions across the complex. Two reasons for this difficulty may be cited. First, classification systems commonly used in industry often fail to cover in sufficient depth the unique demands of DOE`s nuclear energy and research community. Second, the government practice of contracting the operation of government facilities to the private sector has introduced numerous contractor-specific classification schemes to the DOE complex. As a result, sites/contractors report their workforce needs using unique classification systems. It becomes difficult, therefore, to roll these data up to the national level necessary to support strategic planning and analysis. The Common Occupational Classification System (COCS) is designed to overcome these workforce planning barriers. The COCS is based on earlier workforce planning activities and the input of technical, workforce planning, and human resource managers from across the DOE complex. It provides a set of mutually-exclusive occupation titles and definitions that cover the broad range of activities present in the DOE complex. The COCS is not a required record-keeping or data management guide. Neither is it intended to replace contractor/DOE-specific classification systems. Instead, the system provides a consistent, high- level, functional structure of occupations to which contractors can crosswalk (map) their job titles.

  2. Common modeling system for digital simulation

    Painter, Rick

    1994-01-01

    The Joint Modeling and Simulation System is a tri-service investigation into a common modeling framework for the development digital models. The basis for the success of this framework is an X-window-based, open systems architecture, object-based/oriented methodology, standard interface approach to digital model construction, configuration, execution, and post processing. For years Department of Defense (DOD) agencies have produced various weapon systems/technologies and typically digital representations of the systems/technologies. These digital representations (models) have also been developed for other reasons such as studies and analysis, Cost Effectiveness Analysis (COEA) tradeoffs, etc. Unfortunately, there have been no Modeling and Simulation (M&S) standards, guidelines, or efforts towards commonality in DOD M&S. The typical scenario is an organization hires a contractor to build hardware and in doing so an digital model may be constructed. Until recently, this model was not even obtained by the organization. Even if it was procured, it was on a unique platform, in a unique language, with unique interfaces, and, with the result being UNIQUE maintenance required. Additionally, the constructors of the model expended more effort in writing the 'infrastructure' of the model/simulation (e.g. user interface, database/database management system, data journalizing/archiving, graphical presentations, environment characteristics, other components in the simulation, etc.) than in producing the model of the desired system. Other side effects include: duplication of efforts; varying assumptions; lack of credibility/validation; and decentralization in policy and execution. J-MASS provides the infrastructure, standards, toolset, and architecture to permit M&S developers and analysts to concentrate on the their area of interest.

  4. Rethinking Soils: an under-investigated commons?

    In a number of global contexts there is a re-awakening of interest in soils in both increasing the resilience of complex social-ecological systems (SES) and as a result of the threats to them, as shown by the UN International Year of Soils in 2015. Consequently the management of soils and their wider role within property regimes and natural resource management might need to be reassessed. At the heart of this is the rise in awareness regarding the connectedness of SES, and in frameworks such as the Ecosystem Approach and the identification and analysis of Ecosystem Services. Whilst not new to some, it has widened the understanding among many, that soils have a valuable role to play in complex SES because they are a slow variable crucial to underlying structure of the SES. The conventional approach that soils are linked to the ecosystem services category of provisioning services (production of food, timber and fibre) remains valid. Not surprisingly this link is strong within natural resource management and property rights regimes but soils remain at risk for a range of threats, for example soil erosion and compaction, salinization, sealing, desertification, loss of organic matter and biodiversity and contamination. However, soils are increasingly seen as a slow variable that can lead to increased resilience within a SES and have a profound importance to human life through a range of regulating services including water quality and purification, water flow and attenuation and , pest and disease control. Given the long-standing importance of soil as a natural resource there are also accompanying legal systems, property regimes, societal values, knowledge, custom and traditions. However, in the light of the wider understanding soil functions are these social frameworks appropriate and fit for purpose or would a shared resource of commons approach be more appropriate. To some extent this examination would also extend to the presence of soils within the cultural services category of ecosystem services. As a result of the increasing evidence regarding soil threats, there is concern that the knowledge relating to soils is fragmented and incomplete. This is particular true regarding the complexity and functioning of soil systems and their interaction with human activities and the effectiveness of governance arrangements to promote resilience in the management of soils. Therefore discussions concerning soils needs to be taken from an interdisciplinary perspectives that embraces both natural and social sciences. This paper will seek to examine soils from a multi-scale governance/complex commons perspective. It will also consider how a commons perspective might be useful in reducing soil threats and in the development of effective prevention, remediation and restoration measures. This often requires a change in thinking about soil, perhaps considering it as a 'slow variable', able to drive long-term change or as a 'cultural asset' and 'knowledge resource'.

  5. Institutional property rights structure, common pool resource (CPR), tragedy of the urban commons: A Review

    There have been a plethora of researches on the significance of public open space (POS) in contributing to societies' sustainability. However, by virtue of identified maladaptive policy-based-property rights structure, such a shared good becomes vulnerable to tragedy of the urban commons (overexploitation) that subsequently leads to burgeoning number of mismanaged POS e.g., degraded and unkempt urban public spaces. By scrutinising the literatures within property rights domain and commons resources, an objective is highlighted in this paper which is to insightfully discourse institutional property rights structure pertaining to the mechanism, roles and interrelationship between property-rights regimes, bundle of property rights and resource domains; types of goods on how they act upon and tie in the POS with the social quandary. In summary, urban POS tragedy can potentially be triggered by the institutional structure especially if the ownership is left under open-access resource regime and ill-defined property rights which both successively constitute the natures of Common Pool Resource (CPR) within the commons, POS. Therefore, this paper sparks an idea to policy makers that property rights structure is a determinant in sustainably governing the POS in which adaptive assignment of property regimes and property rights are impelled.

  12. Core radii and common-envelope evolution

    Hall, Philip D.; Tout, Christopher A.

    2014-11-01

    Many classes of objects and events are thought to form in binary star systems after a phase in which a core and companion spiral to smaller separation inside a common envelope (CE). Such a phase can end with the merging of the two stars or with the ejection of the envelope to leave a surviving binary system. The outcome is usually predicted by calculating the separation to which the stars must spiral to eject the envelope, assuming that the ratio of the core-envelope binding energy to the change in orbital energy is equal to a constant efficiency factor ?. If either object would overfill its Roche lobe at this end-of-CE separation, then the stars are assumed to merge. It is unclear what critical radius should be compared to the end-of-CE Roche lobe for stars which have developed cores before the start of a CE phase. After improving the core radius formulae in the widely used BSE rapid evolution code, we compare the properties of populations in which the critical radius is chosen to be the pre-CE core radius or the post-CE stripped remnant radius. Our improvements to the core radius formulae and the uncertainty in the critical radius significantly affect the rates of merging in CE phases of most types. We find the types of systems for which these changes are most important.

    Context .- There is no current standard among myopathologists for reporting muscle biopsy findings. The National Institute of Neurological Disorders and Stroke has recently launched a common data element (CDE) project to standardize neuromuscular data collected in clinical reports and to facilitate their use in research. Objective .- To develop a more-uniform, prospective reporting tool for muscle biopsies, incorporating the elements identified by the CDE project, in an effort to improve reporting and educational resources. Design .- The variation in current biopsy reporting practice was evaluated through a study of 51 muscle biopsy reports from self-reported diagnoses of genetically confirmed or undiagnosed muscle disease from the Congenital Muscle Disease International Registry. Two reviewers independently extracted data from deidentified reports and entered them into the revised CDE format to identify what was missing and whether or not information provided on the revised CDE report (complete/incomplete) could be successfully interpreted by a neuropathologist. Results .- Analysis of the data highlighted showed (1) inconsistent reporting of key clinical features from referring physicians, and (2) considerable variability in the reporting of pertinent positive and negative histologic findings by pathologists. Conclusions .- We propose a format for muscle-biopsy reporting that includes the elements in the CDE checklist and a brief narrative comment that interprets the data in support of a final interpretation. Such a format standardizes cataloging of pathologic findings across the spectrum of muscle diseases and serves emerging clinical care and research needs with the expansion of genetic-testing therapeutic trials.

    2008-06-11

    When simulating light collection in scintillators, modeling the angular distribution of optical light reflectance from surfaces is very important. Since light reflectance is poorly understood, either purely specular or purely diffuse reflectance is generally assumed. In this paper we measure the optical reflectance distribution for eleven commonly used reflectors. A 440 nm, output power stabilized, un-polarized laser is shone onto a reflector at a fixed angle of incidence. The reflected light's angular distribution is measured by an array of silicon photodiodes. The photodiodes are movable to cover 2 pi of solid angle. The light-induced current is, through a multiplexer, read out with a digital multimeter. A LabVIEW program controls the motion of the laser and the photodiode array, the multiplexer, and the data collection. The laser can be positioned at any angle with a position accuracy of 10 arc minutes. Each photodiode subtends 6.3o, and the photodiode array can be positioned at any angle with up to 10 arc minute angular resolution. The dynamic range for the current measurements is 105:1. The measured light reflectance distribution was measured to be specular for several ESR films as well as for aluminum foil, mostly diffuse for polytetrafluoroethylene (PTFE) tape and titanium dioxide paint, and neither specular nor diffuse for Lumirror(R), Melinex(R) and Tyvek(R). Instead, a more complicated light distribution was measured for these three materials.

    2003-04-01

    This narrative review provides evidence-based explanations to some of the common clinical concerns regarding inhaled corticosteroids. Inhaled corticosteroids are the treatment of choice for a newly diagnosed asthmatic patient. Better results are obtained when treatment is initiated as soon as the diagnosis is made. Asthma control can be achieved and maintained in most patients with a low or moderate dose of inhaled corticosteroid administered in two daily doses. Longer duration of treatment provides more sustained benefits than treatment that is intermittent and for short periods of time. The clinical benefits can be observed within 24 hours of commencing treatment and may be more pronounced in patients with an eosinophilic bronchitis. Inhaled corticosteroids provide additional benefit when used in conjunction with prednisone in acute severe asthma. Low doses do not have clinically deleterious side effects on the bones, growth, eye, or hypothalamo-pituitary-adrenal-axis. However, they do not normalize lung function and prevent structural changes in the airway wall in all asthmatic patients. PMID:12765311

  18. Asymmetric Accretion Flows within a Common Envelope

    E-print Network

    MacLeod, Morgan

    2014-01-01

    This paper examines flows in the immediate vicinity of stars and compact objects dynamically inspiralling within a common envelope (CE). These embedded objects spiral to tighter separations because of drag that is generated when gas collides and shocks as it is gravitationally focused. This flow convergence is expected to lead to gas accretion onto the inspiralling object. This process has been studied numerically and analytically in the context of Hoyle-Lyttleton accretion (HLA). Yet, within a CE, accretion structures may span a large fraction of the envelope radius, and in so doing sweep across a substantial radial gradient of density. We quantify these gradients using detailed stellar evolution models for a range of CE encounters. We provide estimates of typical scales in CE encounters that involve main sequence stars, white dwarfs, neutron stars, and black holes with giant-branch companions of a wide range of masses. We apply these typical scales to hydrodynamic simulations of 3D HLA with an upstream dens...

    2003-01-01

    A variety of slipmeters have been used to assess the slipperiness of floor surfaces. International standards for the operation of slipmeters describe the protocol for a single measurement. These standards usually do not cover some of the critical elements in safety assessment such as methods for the selection of measurement locations and the necessary number of repeated measurements at each location. Furthermore, most of the slipmeters were evaluated in laboratory settings with new floor surfaces and artificial contaminants. Two commonly used slipmeters, the Brungraber Mark II and the English XL, were evaluated at actual worksites in this experiment. Four floor tiles in each of four different work areas in the kitchens of 18 fast food restaurants were selected for repeated measurements with these two slipmeters. The results indicated that sanding of footwear materials has a significant effect on the outcomes of friction measurements, and the tile-to-tile variations in friction in the same areas of restaurants were also mostly statistically significant. Significant local variation in friction among tiles in the same area could potentially increase the chances of slip and fall incidents. Both slipmeters used in this experiment could potentially have problems in the areas with grease, such as grill and fryer areas, since the build-up of grease during repeated strikes could alter the outcome of friction measured.

    Seventeen commonly used dyes and 16 of their metabolites or derivatives were tested in the Salmonella-mammalian microsome mutagenicity test. Mutagens active with and without added Aroclor-induced rat liver microsome preparations (S9) were 3-aminopyrene, lithol red, methylene blue (USP), methyl yellow, neutral red, and phenol red. Those mutagenic only with S9 activation were 4-aminopyrazolone, 2,4-dimethylaniline, N,N-dimethyl-p-phenylenediamine, methyl red, and 4-phenyl-azo-1-naphthylamine. Orange II was mutagenic only without added S9. Nonmutagenic azo dyes were allura red, amaranth, ponceau R, ponceau SX, sunset yellow, and tartrazine. Miscellaneous dyes not mutagenic were methyl green, methyl violet 2B, and nigrosin. Metabolites of the azo dyes that were not mutagenic were 1-amino-2-naphthol hydrochloride, aniline, anthranilic acid, cresidine salt, pyrazolone T,R-amino salt (1-amino-2-naphthol-3,6-disulfonic disodium salt), R-salt, Schaeffer's salt (2-naphthol-6-sulfonic acid, sodium salt), sodium naphthionate, sulfanilamide, and sulfanilic acid. 4-Amino-1-naphthalenesulfonic acid sodium salt was also not mutagenic. Fusobacterium sp. 2 could reductively cleave methyl yellow to N,N-dimethyl-p-phenylenediamine which was then activated to a mutagen. PMID:7039509

    2012-03-15

    The prevalence of benign anorectal conditions in the primary care setting is high, although evidence of effective therapy is often lacking. In addition to recognizing common benign anorectal disorders, physicians must maintain a high index of suspicion for inflammatory and malignant disorders. Patients with red flags such as increased age, family history, persistent anorectal bleeding despite treatment, weight loss, or iron deficiency anemia should undergo colonoscopy. Pruritus ani, or perianal itching, is managed by treating the underlying cause, ensuring proper hygiene, and providing symptomatic relief with oral antihistamines, topical steroids, or topical capsaicin. Effective treatments for anal fissures include onabotulinumtoxinA, topical nitroglycerin, and topical calcium channel blockers. Symptomatic external hemorrhoids are managed with dietary modifications, topical steroids, and analgesics. Thrombosed hemorrhoids are best treated with hemorrhoidectomy if symptoms are present for less than 72 hours. Grades I through III internal hemorrhoids can be managed with rubber band ligation. For the treatment of grade III internal hemorrhoids, surgical hemorrhoidectomy has higher remission rates but increased pain and complication rates compared with rubber band ligation. Anorectal condylomas, or anogenital warts, are treated based on size and location, with office treatment consisting of topical trichloroacetic acid or podophyllin, cryotherapy, or laser treatment. Simple anorectal fistulas can be treated conservatively with sitz baths and analgesics, whereas complex or nonhealing fistulas may require surgery. Fecal impaction may be treated with polyethylene glycol, enemas, or manual disimpaction. Fecal incontinence is generally treated with loperamide and biofeedback. Surgical intervention is reserved for anal sphincter injury. PMID:22534276

    Noise injury in agriculture is a significant yet often unrecognized problem. Many farmers, farm workers, and family members are exposed to noise levels above recommended levels and have greater hearing loss than their non-farming contemporaries. The aim of this study was to gather up-to-date information on farm noise levels and to enhance the quality of information available to assist farmers in reducing noise exposure and meeting Occupational Health and Safety (OHS) regulations regarding noise management. Farm visits were conducted on 48 agricultural establishments that produce a range of commodities. Noise levels were measured at the ears of operators and bystanders involved in typical activities on farms. The average and peak noise levels were measured for 56 types of machinery or sites of farming activity, totaling 298 separate items and activities. Common noise hazards identified included firearms, tractors without cabs, workshop tools, small motors (e.g., chainsaws, augers, pumps), manual handling of pigs, shearing sheds, older cabbed tractors, and heavy machinery such as harvesters, bulldozers, and cotton module presses. We found that use of firearms without hearing protection presents a pressing hearing health priority. However, farming activities involving machinery used for prolonged periods also present significant risks to farmers' hearing health. Noise management strategies on the farm are essential in order to prevent noise injury among farmers. PMID:16184791

  3. Differential gene detection incorporating common expression patterns

    NASA Astrophysics Data System (ADS)

    Oba, Shigeyuki; Ishii, Shin

    2009-12-01

    In detection of differentially expressed (DE) genes between different groups of samples based on a high-throughput expression measurement system, we often use a classical statistical testing based on a simple assumption that the expression of a certain DE gene in one group is higher or lower in average than that in the other group. Based on this simple assumption, the theory of optimal discovery procedure (ODP) (Storey, 2005) provided an optimal thresholding function for DE gene detection. However, expression patterns of DE genes over samples may have such a structure that is not exactly consistent with group labels assigned to the samples. Appropriate treatment of such a structure can increase the detection ability. Namely, genes showing similar expression patterns to other biologically meaningful genes can be regarded as statistically more significant than those showing expression patterns independent of other genes, even if differences in mean expression levels are comparable. In this study, we propose a new statistical thresholding function based on a latent variable model incorporating expression patterns together with the ODP theory. The latent variable model assumes hidden common signals behind expression patterns over samples and the ODP theory is extended to involve the latent variables. When applied to several gene expression data matrices which include cluster structures or 'cancer outlier' structures, the newly-proposed thresholding functions showed prominently better detection performance of DE genes than the original ODP thresholding function did. We also demonstrate how the proposed methods behave through analyses of real breast cancer and lymphoma datasets.

    Examples of extrachromosomal circular DNAs (eccDNAs) are found in many organisms, but their impact on genetic variation at the genome scale has not been investigated. We mapped 1,756 eccDNAs in the Saccharomyces cerevisiae genome using Circle-Seq, a highly sensitive eccDNA purification method. Yeast eccDNAs ranged from an arbitrary lower limit of 1 kb up to 38 kb and covered 23% of the genome, representing thousands of genes. EccDNA arose both from genomic regions with repetitive sequences ?15 bases long and from regions with short or no repetitive sequences. Some eccDNAs were identified in several yeast populations. These eccDNAs contained ribosomal genes, transposon remnants, and tandemly repeated genes (HXT6/7, ENA1/2/5, and CUP1-1/-2) that were generally enriched on eccDNAs. EccDNAs seemed to be replicated and 80% contained consensus sequences for autonomous replication origins that could explain their maintenance. Our data suggest that eccDNAs are common in S. cerevisiae, where they might contribute substantially to genetic variation and evolution. PMID:26038577

    2001-08-01

    The development of a modularized millimeter wave (MMW) target and background high resolution scene generator is reported. The scene generator's underlying algorithms are applicable to both digital and real-time hardware-in-the-loop (HWIL) simulations. The scene generator will be configurable for a variety of MMW and multi-mode sensors employing state of the art signal processing techniques. At present, digital simulations for MMW and multi-mode sensor development and testing are custom-designed by the seeker vendor and are verified, validated, and operated by both the vendor and government in simulation-based acquisition. A typical competition may involve several vendors, each requiring high resolution target and background models for proper exercise of seeker algorithms. There is a need and desire by both the government and sensor vendors to eliminate costly re-design and re-development of digital simulations. Additional efficiencies are realized by assuring commonality between digital and HWIL simulation MMW scene generators, eliminating duplication of verification and validation efforts.

  6. Common Attentional Constraints in Visual Foraging

    2014-01-01

    Predators are known to select food of the same type in non-random sequences or “runs” that are longer than would be expected by chance. If prey are conspicuous, predators will switch between available sources, interleaving runs of different prey types. However, when prey are cryptic, predators tend to focus on one food type at a time, effectively ignoring equally available sources. This latter finding is regarded as a key indicator that animal foraging is strongly constrained by attention. It is unknown whether human foraging is equally constrained. Here, using a novel iPad task, we demonstrate for the first time that it is. Participants were required to locate and touch 40 targets from 2 different categories embedded within a dense field of distractors. When individual target items “popped-out” search was organized into multiple runs, with frequent switching between target categories. In contrast, as soon as focused attention was required to identify individual targets, participants typically exhausted one entire category before beginning to search for the other. This commonality in animal and human foraging is compelling given the additional cognitive tools available to humans, and suggests that attention constrains search behavior in a similar way across a broad range of species.

    We studied communal roosting in the Common Myna (Acridotheres tristis) in the light of the recruitment centre hypothesis and predation at the roost. The number and sizes of flocks departing from and arriving at focal roosts were recorded over a two year period. We also recorded the sizes and behaviour of foraging flocks. We found that flock sizes of birds departing from roosts at sunrise were larger than those at the feeding site, suggesting that there was no recruitment from the roosts. Flocks entering the roosts during sunset were larger on average than those leaving the following sunrise, suggesting no consolidation of flocks in the morning. Flocks entering the roosts at sunset were also larger on average than those that had left that sunrise, although there was no recruitment at the feeding site. There was no effect of group size on the proportion of time spent feeding. Contrary to expectation, single birds showed lower apparent vigilance than birds that foraged in pairs or groups, possibly due to scrounging tactics being used in the presence of feeding companions. Thus, the recruitment centre hypothesis did not hold in our study population of mynas. Predation at dawn and dusk were also not important to communal roosting: predators near the roosts did not result in larger flocks, and resulted in larger durations of arrival/departure contrary to expectation. Since flock sizes were smallest at the feeding site and larger in the evening than in the morning, but did not coincide with predator activity, information transfer unrelated to food (such as breeding opportunities) may possibly give rise to the evening aggregations.

    Fundamental problems of environmental sustainability, including climate change and fisheries management, require collective action on a scale that transcends the political and cultural boundaries of the nation-state. Rational, self-interested neoclassical economic theories of human behavior predict tragedy in the absence of third party enforcement of agreements and practical difficulties that prevent privatization. Evolutionary biology offers a theory of cooperation, but more often than not in a context of discrimination against other groups. That is, in-group boundaries are necessarily defined by those excluded as members of out-groups. However, in some settings human's exhibit behavior that is inconsistent with both rational economic and group driven cooperation of evolutionary biological theory. This paper reports the results of a non-cooperative game-theoretic exercise that models a tragedy of the commons problem in which groups of players may advance their own positions only at the expense of other groups. Students enrolled from multiple universities and assigned to different multi-university identity groups participated in experiments that repeatedly resulted in cooperative outcomes despite intergroup conflicts and expressions of group identity. We offer three possible explanations: (1) students were cooperative because they were in an academic setting; (2) students may have viewed their instructors as the out-group; or (3) the emergence of a small number of influential, ethical leaders is sufficient to ensure cooperation amongst the larger groups. From our data and analysis, we draw out lessons that may help to inform approaches for institutional design and policy negotiations, particularly in climate change management. PMID:25082500

The tunnel was tilted to simulate descending flight at different sink speeds. The swift varied its wingspan, wing area and tail span over the speed range. Wingspan decreased linearly with speed, whereas tail span decreased in a nonlinear manner. For each airspeed, the minimum glide angle was found. The corresponding sink speeds showed a curvilinear relationship with airspeed, with a minimum sink speed at 8.1 m s(-1) and a speed of best glide at 9.4 m s(-1). Lift-to-drag ratio was calculated for each airspeed and tilt angle combinations and the maximum for each speed showed a curvilinear relationship with airspeed, with a maximum of 12.5 at an airspeed of 9.5 m s(-1). Wake was sampled in the transverse plane using stereo digital particle image velocimetry (DPIV). The main structures of the wake were a pair of trailing wingtip vortices and a pair of trailing tail vortices. Circulation of these was measured and a model was constructed that showed good weight support. Parasite drag was estimated from the wake defect measured in the wake behind the body. Parasite drag coefficient ranged from 0.30 to 0.22 over the range of airspeeds. Induced drag was calculated and used to estimate profile drag coefficient, which was found to be in the same range as that previously measured on a Harris' hawk. PMID:21228197

    cDNAs encoding (+)-bornyl diphosphate synthase, 1,8-cineole synthase and (+)-sabinene synthase from common sage (Salvia officinalis) have been isolated and sequenced, and the corresponding amino acid sequences has been determined. Accordingly, isolated DNA sequences (SEQ ID No:1; SEQ ID No:3 and SEQ ID No:5) are provided which code for the expression of (+)-bornyl diphosphate synthase (SEQ ID No:2), 1,8-cineole synthase (SEQ ID No:4) and (+)-sabinene synthase SEQ ID No:6), respectively, from sage (Salvia officinalis). In other aspects, replicable recombinant cloning vehicles are provided which code for (+)-bornyl diphosphate synthase, 1,8-cineole synthase or (+)-sabinene synthase, or for a base sequence sufficiently complementary to at least a portion of (+)-bornyl diphosphate synthase, 1,8-cineole synthase or (+)-sabinene synthase DNA or RNA to enable hybridization therewith. In yet other aspects, modified host cells are provided that have been transformed, transfected, infected and/or injected with a recombinant cloning vehicle and/or DNA sequence encoding (+)-bornyl diphosphate synthase, 1,8-cineole synthase or (+)-sabinene synthase. Thus, systems and methods are provided for the recombinant expression of the aforementioned recombinant monoterpene synthases that may be used to facilitate their production, isolation and purification in significant amounts. Recombinant (+)-bornyl diphosphate synthase, 1,8-cineole synthase and (+)-sabinene synthase may be used to obtain expression or enhanced expression of (+)-bornyl diphosphate synthase, 1,8-cineole synthase and (+)-sabinene synthase in plants in order to enhance the production of monoterpenoids, or may be otherwise employed for the regulation or expression of (+)-bornyl diphosphate synthase, 1,8-cineole synthase and (+)-sabinene synthase, or the production of their products.

    To encourage the process of harmonization, the biobank community should support and use a common terminology. Relevant terms may be found in general thesauri for medicine, legal instruments or specific glossaries for biobanking. A comparison of the use of these sources has so far not been conducted and would be a useful instrument to further promote harmonization and data sharing. Thus, the purpose of the present study was to investigate the preference of definitions important for sharing biological samples and data. Definitions for 10 terms -[human] biobank, sample/specimen, sample collection, study, aliquot, coded, identifying information, anonymised, personal data and informed consent-were collected from several sources. A web-based questionnaire was sent to 560 European individuals working with biobanks asking to select their preferred definition for the terms. A total of 123 people participated in the survey, giving a response rate of 23%. The result was evaluated from four aspects: scope of definitions, potential regional differences, differences in semantics and definitions in the context of ontologies, guided by comments from responders. Indicative from the survey is the risk of focusing only on the research aspect of biobanking in definitions. Hence, it is recommended that important terms should be formulated in such a way that all areas of biobanking are covered to improve the bridges between research and clinical application. Since several of the terms investigated here within can also be found in a legal context, which may differ between countries, establishing what is a proper definition on how it adheres to law is also crucial.

    Abstract The double-bubble deformity is one of the most common problems in breast augmentation, with or without mastopexy. Classically, open techniques have been used to treat this deformity, including elevation and reconstruction of the inframammary crease or parenchymal scoring. In this study, the author reports experience with a simple, closed technique of serial fat grafting procedures to treat the double-bubble deformity. Twenty-eight patients with double-bubble deformities were retrospectively evaluated. Fifteen patients had undergone primary augmentation, whereas 13 patients had undergone augmentation mastopexy. Eight patients presented with bilateral double-bubble deformity. Up to 3 sessions of fat grafting were performed on each patient, with a mean of 2.1 sessions required for patients in the series. An average of 27 cm3 of fat was injected with each treatment per breast. Fat was injected with a 1.5-mm blunt cannula into the subdermal and superficial breast tissue layers beneath the old inframammary fold. There were no oil cysts, infections, or donor site problems noted in the series. Twelve patients with limited breast tissue underwent magnetic resonance imaging examination at the conclusion of the fat grafting sessions, and no implant injury or disruption was noted. All patients were pleased with the results of treatment, and no revisional surgery was required. This study suggests that fat grafting is an effective treatment of the breast double-bubble deformity. The procedure allows the correction of a challenging deformity with a simple, closed technique which is safe and cost-effective. PMID:26101976

    This is the final report documenting the results of the polarization testing of near-planar objects with various reflectance properties. The purpose of this investigation was to determine the portion of the reflected signal which is polarized for materials commonly used in space applications. Tests were conducted on several samples, with surface characteristics ranging from highly reflective to relatively dark. The measurements were obtained by suspending the test object in a beam of collimated light. The amount of light falling on the sample was controlled by a circular aperture placed in the light field. The polarized reflectance at various phase angles was then measured. A nonlinear least squares fitting program was used for analysis. For the specular test objects, the reflected signals were measured in one degree increments near the specular point. Otherwise, measurements were taken every five degrees in phase angle. Generally, the more diffuse surfaces had lower polarized reflectances than their more specular counterparts. The reflected signals for the more diffuse surfaces were spread over a larger phase angle range, while the signals from the more specular samples were reflected almost entirely within five degrees of angular deviation from the specular point. The method used to test all the surfaces is presented. The results of this study will be used to support the NASA Orbital Debris Optical Signature Tests. These tests are intended to help better understand the reflectance properties of materials often used in space applications. This data will then be used to improve the capabilities for identification and tracking of space debris.

  14. Estimating carnivoran diets using a combination of carcass observations and scats from GPS clusters.

    Scat analysis is one of the most frequently used methods to assess carnivoran diets and Global Positioning System (GPS) cluster methods are increasingly being used to locate feeding sites for large carnivorans. However, both methods have inherent biases that limit their use. GPS methods to locate kill sites are biased towards large carcasses, while scat analysis over-estimates the biomass consumed from smaller prey. We combined carcass observations and scats collected along known movement routes, assessed using GPS data from four African lion (Panthera leo) prides in the Kruger National Park, South Africa, to determine how a combination of these two datasets change diet estimates. As expected, using carcasses alone under-estimated the number of feeding events on small species, primarily impala (Aepyceros melampus) and warthog (Phacochoerus africanus), in our case by more than 50% and thus significantly under-estimated the biomass consumed per pride per day in comparison to when the diet was assessed using carcass observations alone. We show that an approach that supplements carcass observations with scats that enables the identification of potentially missed feeding events increases the estimates of food intake rates for large carnivorans, with possible ramifications for predator-prey interaction studies dealing with biomass intake rate.

    Warthog (Phacochoerus aethiopicus), giant forest hog (Hylochoerus meinertzhageni) and bushpig (Potamochoerus porcus) are known to be susceptible to infection with African swine fever (ASF) virus. Little however, is known about the ecology of the disease in the bushpig. This study has shown that the bushpig remains viraemic for between 35 and 91 days following infection during which time it is able to infect the tick vector O. moubata. These ticks were able to transmit the disease to pigs. The virus persists in the lymphatic tissues for less than 34 weeks. Bushpigs infected with LIL 20/l virus but not VIC T90/l virus transmitted infection to in-contact pigs. Infected domestic pigs did not transmit the infection to in-contact bushpigs. ASF virus was able to replicate in in vitro cultures of bushpig leucocytes and endothelial cells. Recovered bushpigs could be reinfected with some strains of virus but not others. While it has been demonstrated that bushpigs remain carriers of ASFV following infection a complete understanding of their significance in the epidemiology of the disease awaits further investigations of their association with O. moubata.

    A survey to determine the prevalence of bovine tuberculosis caused by Mycobacterium bovis and certain other infectious diseases was conducted on 42 free-ranging African buffaloes, (Syncerus caffer) from May to June 1997 in the Queen Elizabeth National Park, Uganda. Using the gamma interferon test, exposure to M. bovis was detected in 21.6% of the buffaloes. One dead buffalo and an emaciated warthog (Phacochoerus aethiopicus) that was euthanased, were necropsied; both had miliary granulomas from which M. bovis was isolated. None of the buffaloes sampled in Sector A of the park, which has no cattle interface, tested positive for bovine tuberculosis (BTB) exposure. The prevalence and distribution of BTB does not appear to have changed significantly since the 1960s, but this may be due to fluxes in the buffalo population. Serological testing for foot-and-mouth disease (FMD) demonstrated positive exposure of 57.1% of the buffaloes sampled, with types A, O and SAT 1-3, which is the first known report of FMD antibodies to A and O types in free ranging African buffaloes. Foot-and-mouth disease virus types SAT 1 and SAT 3 were isolated from buffalo probang samples. Two percent of the buffaloes had been exposed to brucellosis. None of the buffaloes tested had antibodies to rinderpest, leptospirosis or Q fever. PMID:16137132

    We provide evidence from isoenzyme analysis, hybridization with repetitive DNA probes, behavioural studies and morphometrics that 4 trypanosome isolates from Glossina morsitans submorsitans in The Gambia constitute a new species now named Trypanosoma (Nannomonas) godfreyi. The bloodstream trypomastigotes of T. (N.) godfreyi are relatively small with a mean length of 13.7 microns (range: 9.1-21.8 microns) and a mean width of 1.65 microns (range: 0.65-2.69 microns). There is no free flagellum and the marginal kinetoplast is subterminal to a rounded posterior end; the undulating membrane is usually conspicuous. As with other Nannomonas, T. godfreyi developed in the midgut and proboscis of Glossina and infections matured in 21-28 days in laboratory G.m. morsitans. In The Gambia the normal vertebrate host appears to be the warthog, Phacochoerus aethiopicus, although elsewhere other wild and domestic suids may also be implicated in the life-cycle. T. godfreyi was identified unequivocally using a 380 bp DNA probe specific for a major genomic repeat sequence; its isoenzyme profile distinguished it clearly from T. simiae and three strain groups of T. congolense: savannah, riverine-forest and kilifi.

    The prevalence of trypanosome infections in tsetse flies in the Chiawa area of Lower Zambezi in Zambia, with endemic trypanosomosis, was determined by a polymerase chain reaction (PCR) method that allowed the detection of trypanosome DNA and determination of the type of animal host fed on by the tsetse fly Glossina pallidipes, using tsetse-derived DNA extracts as templates. Ninety G. pallidipes (82 females and 8 males; 18.3%) of the 492 flies captured by baited biconical traps tested positive for the presence of Trypanosoma brucei species genomic DNA. Of the 90 T. brucei-positive flies, 47 (52.2%) also tested positive for vertebrate mitochondrial DNA. Sequence analysis of the vertebrate mitochondrial DNA amplicons established that they originated from 8 different vertebrate species, namely, human (Homo sapiens), African elephant (Loxodonta cyclotis), African buffalo (Syncerus caffer), waterbuck (Kobus ellipsiprymnus), roan antelope (Hippotragus equinus), greater kudu (Tragelaphus strepsiceros), warthog (Phacochoerus africanus), and goat (Capra hircus). Furthermore, to investigate the prevalence of trypanosome infections in domestic goats in the same area where trypanosomes had been detected in tsetse files, a total of 86 goats were randomly selected from 6 different herds. Among the selected goats, 36 (41.9%) were found to be positive for T. brucei species. This combined detection method would be an ideal approach not only for mass screening for infection prevalence in tsetse populations, but also for the prediction of natural reservoirs in areas endemic for trypanosomosis.

    Within a survey of parasitic infections in wild mammals of Somalia, during the first semester of 1983 and the second of 1984, endoparasites were collected from 11 host species: Gazella soemmeringi, Gazella spekei, Madoqua saltiana, Phacochoerus aethiopicus, Xerus rutilus, Lepus sp., Genetta genetta, Herpestes (Galerella) sanguineus, Felis sylvestris libyca, Felis caracal, Canis mesomelas. A total of 22 species of helminths (20 nematode and 2 metacestode species) were identified. Lepus sp. is a new host for Heteroxinema (P.) proboscidiphora and Herpestes sanguineus for Oxinema sp. Teladorsagia hamata had not been previously reported in G. spekei; the genital cone and the corresponding supporting apparatus of this nematode are described. Two metacestodes were collected from the mesenteric membranes of a P. aethiopicus. The shape, number and length of their rostellar hooks, the size of the larvocysts, the occurrence of pseudostrobilum, are similar to those of the Taenia regis metacestode: but the size and shape of the hooks of the Somalian warthog larvocysts are slightly different and they have not been recovered from the musculature as previously reported in the intermediate hosts of T. regis.

    The durations of the developmental periods of Rhipicephalus lunulatus at 25 degrees C and 87% RH were: preoviposition, 2-9 days; oviposition, 29-34 days; minimum incubation, 11-27 days; nymphal premoult period, 11-23 days; and adult premoult period, 19-30 days. The durations of the feeding periods on a rabbit were: 3-7 days for larvae and 4-11 days for nymphs. Adult feeding was completed on a rabbit and a sheep in 10-22 days in January and 14-64 days in September, and only fertilized females completed engorgement. The mean number of eggs laid by engorged females was 4732, with 95% being laid within the first 16 days. In the southeastern lowveld of Zimbabwe adult ticks were most abundant on cattle between November and December, and their preferred sites of attachment were the legs and tail. Other hosts of adult R. lunulatus were impala (Aepyceros melampus), warthog (Phacochoerus aethiopicus), kudu (Tragelaphus strepsiceros) and eland (Taurotragus oryx). PMID:3870962

  10. JPSS Common Ground System Multimission Support

    NASA Astrophysics Data System (ADS)

    Jamilkowski, M. L.; Miller, S. W.; Grant, K. D.

    2013-12-01

    NOAA & NASA jointly acquire the next-generation civilian operational weather satellite: Joint Polar Satellite System (JPSS). JPSS contributes the afternoon orbit & restructured NPOESS ground system (GS) to replace the current Polar-orbiting Operational Environmental Satellite (POES) system run by NOAA. JPSS sensors will collect meteorological, oceanographic, climatological & solar-geophysical observations of the earth, atmosphere & space. The JPSS GS is the Common Ground System (CGS), consisting of Command, Control, & Communications (C3S) and Interface Data Processing (IDPS) segments, both developed by Raytheon Intelligence, Information & Services (IIS). CGS now flies the Suomi National Polar-orbiting Partnership (S-NPP) satellite, transfers its mission data between ground facilities and processes its data into Environmental Data Records for NOAA & Defense (DoD) weather centers. CGS will expand to support JPSS-1 in 2017. The JPSS CGS currently does data processing (DP) for S-NPP, creating multiple TBs/day across over two dozen environmental data products (EDPs). The workload doubles after JPSS-1 launch. But CGS goes well beyond S-NPP & JPSS mission management & DP by providing data routing support to operational centers & missions worldwide. The CGS supports several other missions: It also provides raw data acquisition, routing & some DP for GCOM-W1. The CGS does data routing for numerous other missions & systems, including USN's Coriolis/Windsat, NASA's SCaN network (including EOS), NSF's McMurdo Station communications, Defense Meteorological Satellite Program (DMSP), and NOAA's POES & EUMETSAT's MetOp satellites. Each of these satellite systems orbits the Earth 14 times/day, downlinking data once or twice/orbit at up to 100s of MBs/second, to support the creation of 10s of TBs of data/day across 100s of EDPs. Raytheon and the US government invested much in Raytheon's mission-management, command & control and data-processing products & capabilities. CGS's flexible, multimission capabilities offer major chances for cost reduction & improved information integration across missions. Raytheon has a unique ability to provide complex, highly-secure, multi-mission GSs. As disaggregation, hosted CGS multimission payloads, and other space-architecture trades are implemented and new sensors come on line that collect orders of magnitude more data, the importance of a flexible, expandable and virtualized modern GS architecture increases. The CGS offers that solution support. JPSS CGS supports 5 global ground stations that can receive S-NPP & JPSS-1 mission data. These, linked with high-bandwidth commercial fiber, quickly transport data to the IDPS for EDP creation & delivery. CGS will process & deliver JPSS-1 data to US operational users in < 80 minutes from time of collection. And CGS leverages this fiber network to provide added data routing for a wide array of global missions. The JPSS CGS is a mature, tested solution for support to operational weather forecasting for civil, military and international partners and climate research. It features a flexible design handling order-of-magnitude increases in data over legacy satellite GSs and meets demanding science accuracy needs. The Raytheon-built JPSS CGS gives the full GS capability, from design & development through operations & sustainment. This lays the foundation for CGS future evolution to support additional missions like Polar Free Flyers.

  11. Are common names becoming less common? The rise in uniqueness and individualism in Japan

    We examined whether Japanese culture has become more individualistic by investigating how the practice of naming babies has changed over time. Cultural psychology has revealed substantial cultural variation in human psychology and behavior, emphasizing the mutual construction of socio-cultural environment and mind. However, much of the past research did not account for the fact that culture is changing. Indeed, archival data on behavior (e.g., divorce rates) suggest a rise in individualism in the U.S. and Japan. In addition to archival data, cultural products (which express an individual’s psyche and behavior outside the head; e.g., advertising) can also reveal cultural change. However, little research has investigated the changes in individualism in East Asia using cultural products. To reveal the dynamic aspects of culture, it is important to present temporal data across cultures. In this study, we examined baby names as a cultural product. If Japanese culture has become more individualistic, parents would be expected to give their children unique names. Using two databases, we calculated the rate of popular baby names between 2004 and 2013. Both databases released the rankings of popular names and their rates within the sample. As Japanese names are generally comprised of both written Chinese characters and their pronunciations, we analyzed these two separately. We found that the rate of popular Chinese characters increased, whereas the rate of popular pronunciations decreased. However, only the rate of popular pronunciations was associated with a previously validated collectivism index. Moreover, we examined the pronunciation variation of common combinations of Chinese characters and the written form variation of common pronunciations. We found that the variation of written forms decreased, whereas the variation of pronunciations increased over time. Taken together, these results showed that parents are giving their children unique names by pairing common Chinese characters with uncommon pronunciations, which indicates an increase in individualism in Japan.

    The goal of this laboratory study was to provide better knowledge about the treatment of ichthyophthiriasis (causative agent: Ichthyophthirius multifiliis, a ciliate bacteria) in rainbow trout Oncorhynchus mykiss and common carp Cyprinus carpio. The following questions were investigated: (1) the effectiveness of different chemicals (formalin, sodium chloride, hydrogen peroxide, Perotan, Virkon, Aquahumin, Baycox, and Ivomec) and at different concentrations and durations of application, (2) the number of treatments and the time intervals between treatments that were necessary to remove the parasite, and (3) how treatment effectiveness differed between the two species. The most effective treatment was a 37% stock solution of formalin at 110 microL/L of bath water for 1 h in rainbow trout and for 2 h in common carp. Aquahumin (150 microL/L for 2 h) was effective in slightly or moderately infected rainbow trout and at low water temperatures, but it was not effective for common carp. All other tested chemicals were ineffective. With formalin and Aquahumin, five treatments were necessary to remove I. multifiliis infestation. At 10 +/- 1 degrees C, the parasites were eradicated when the treatment was performed at 48-h intervals. At 18 +/- 1 degrees C the infestation was eliminated when treatment was performed at 24-h intervals but not at 48-h intervals. At 25 +/- 1 degrees C, treatment at 24-h intervals was ineffective; however, shorter intervals between treatments might improve treatment efficacy at this temperature. In contrast, the number of treatment repetitions played a minor role, and parasites were eliminated with five treatments in all experiments when the type of chemical and treatment interval were optimal.

  13. A Common Law Mortgage on a Common Law Lease on a Space Resource is Legally Available

    NASA Astrophysics Data System (ADS)

    O'Donnell, D. J.

    2002-01-01

    Space Objects are subject to the law of the launching states under the Outer Space Treaty, but space resources, those natural resources already located in space, are not subject to any law other than the treaty laws applicable thereto. In this case of "creditor's rights," there is a void in the treaty regime, except for the proposition that all space resources are public property, (thus inferring that private ownership is not legally possible). However, the law of public property clearly allows possessory estates on common grounds that are not official monuments. The common law development for 750 years has maintained possessory estates as readily available: these are the trust, the lease, the easement, and the mortgage. These estates exists as legal superstructures independent from the underlying physical property. Thus, we could have a 99- year lease of the Apollo 17 landing site on iron ore on the Moon that is mortgaged for a trillion dollars or so, subsequently defaulted, and foreclosed in any Court of General Jurisdiction in favor of the creditor as the new owner. The creditor ends up with the remaining term on the lease, but not with any ownership of the site, the iron ore, and not with ownership of any part of the Moon: It is still public property. This is not only legally available today, it is the exact history of common law estates, (none of which impair legal title by definition and precedent). This model will be discussed as a likely way for astro law to evolve. Association; President of United Societies in Space, Inc., and of its Regency of United Societies in Space, Inc.

    The monitoring of cancer survival by population-based cancer registries is a prerequisite to evaluate the current quality of cancer care. Our study provides 1-, 5- and 10-year relative survival as well as 5-year relative survival conditional on 1-year survival estimates and recent survival trends for Germany using data from 11 population-based cancer registries, covering around one-third of the German population. Period analysis was used to estimate relative survival for 24 common and 11 less common cancer sites for the period 2007-2010. The German and the United States survival estimates were compared using the Surveillance, Epidemiology and End Results 13 database. Trends in cancer survival in Germany between 2002-2004 and 2008-2010 were described. Five-year relative survival increased in Germany from 2002-2004 to 2008-2010 for most cancer sites. Among the 24 most common cancers, largest improvements were seen for multiple myeloma (8.0% units), non-Hodgkin lymphoma (6.2% units), prostate cancer (5.2% units) and colorectal cancer (4.6% units). In 2007-2010, the survival disadvantage in Germany compared to the United States was largest for cancers of the mouth/pharynx (-11.0% units), thyroid (-6.8% units) and prostate (-7.5% units). Although survival estimates were much lower for elderly patients in both countries, differences in age patterns were observed for some cancer sites. The reported improvements in cancer survival might reflect advances in the quality of cancer care on the population level as well as increased use of screening in Germany. The survival differences across countries and the survival disadvantage in the elderly require further investigation. PMID:25380088

    In this paper, the empirical data collected through experiments performed using a FeFET in the common-gate amplifier circuit is presented. The FeFET common-gate amplifier was characterized by varying all parameters in the circuit, such as load resistance, biasing of the transistor, and input voltages. Due to the polarization of the ferroelectric layer, the particular behavior of the FeFET common-gate amplifier presents interesting results. Furthermore, the differences between a FeFET common-gate amplifier and a MOSFET common-gate amplifier are examined.

    Traumatic brain injury (TBI) is a major public health issue exacting a substantial personal and economic burden globally. With the advent of "big data" approaches to understanding complex systems, there is the potential to greatly accelerate knowledge about mechanisms of injury and how to detect and modify them to improve patient outcomes. High quality, well-defined data are critical to the success of bioinformatics platforms, and a data dictionary of "common data elements" (CDEs), as well as "unique data elements" has been created for clinical TBI research. There is no data dictionary, however, for preclinical TBI research despite similar opportunities to accelerate knowledge. To address this gap, a committee of experts was tasked with creating a defined set of data elements to further collaboration across laboratories and enable the merging of data for meta-analysis. The CDEs were subdivided into a Core module for data elements relevant to most, if not all, studies, and Injury-Model-Specific modules for non-generalizable data elements. The purpose of this article is to provide both an overview of TBI models and the CDEs pertinent to these models to facilitate a common language for preclinical TBI research. PMID:26058402

    The demand for cloned genes has increased incessantly over the past 32 years, but some who need recombinant plasmids struggle to produce them. While the pitfalls of traditional ligation-dependent cloning are non-trivial, most can be avoided with sufficient effort and attention to detail. Here, the chemical properties of enzymes and reagents used to clone genes into plasmids are reviewed to draw attention to the most pertinent details. In particular, the virtues of agarose gel electrophoresis monitoring, the nature of the interactions between DNA and silica, and challenges associated with thermostable DNA polymerases, restriction endonucleases, and T4 DNA ligase are explored. Common pitfalls associated with Escherichia coli transformation and DNA modifying enzymes are also described. A thorough understanding of established methods is essential for troubleshooting, implementing alternative approaches, and inventing new techniques in response to changes in technology and demand.

  3. Simulated population responses of common carp to commercial exploitation

    SciTech Connect

    Weber, Michael J.; Hennen, Matthew J.; Brown, Michael L.

    2011-12-01

    Common carp Cyprinus carpio is a widespread invasive species that can become highly abundant and impose deleterious ecosystem effects. Thus, aquatic resource managers are interested in controlling common carp populations. Control of invasive common carp populations is difficult, due in part to the inherent uncertainty of how populations respond to exploitation. To understand how common carp populations respond to exploitation, we evaluated common carp population dynamics (recruitment, growth, and mortality) in three natural lakes in eastern South Dakota. Common carp exhibited similar population dynamics across these three systems that were characterized by consistent recruitment (ages 3 to 15 years present), fast growth (K = 0.37 to 0.59), and low mortality (A = 1 to 7%). We then modeled the effects of commercial exploitation on size structure, abundance, and egg production to determine its utility as a management tool to control populations. All three populations responded similarly to exploitation simulations with a 575-mm length restriction, representing commercial gear selectivity. Simulated common carp size structure modestly declined (9 to 37%) in all simulations. Abundance of common carp declined dramatically (28 to 56%) at low levels of exploitation (0 to 20%) but exploitation >40% had little additive effect and populations were only reduced by 49 to 79% despite high exploitation (>90%). Maximum lifetime egg production was reduced from 77 to 89% at a moderate level of exploitation (40%), indicating the potential for recruitment overfishing. Exploitation further reduced common carp size structure, abundance, and egg production when simulations were not size selective. Our results provide insights to how common carp populations may respond to exploitation. Although commercial exploitation may be able to partially control populations, an integrated removal approach that removes all sizes of common carp has a greater chance of controlling population abundance and reducing perturbations induced by this invasive species.

  4. Joint Service Common Operating Environment (COE) Common Geographic Information System functional requirements

    Meitzler, W.D.

    1992-06-01

    In the context of this document and COE, the Geographic Information Systems (GIS) are decision support systems involving the integration of spatially referenced data in a problem solving environment. They are digital computer systems for capturing, processing, managing, displaying, modeling, and analyzing geographically referenced spatial data which are described by attribute data and location. The ability to perform spatial analysis and the ability to combine two or more data sets to create new spatial information differentiates a GIS from other computer mapping systems. While the CCGIS allows for data editing and input, its primary purpose is not to prepare data, but rather to manipulate, analyte, and clarify it.
