    Conflict between native amphibians and aquatic weed management in the Pacific Northwest is rarely recognized because most native stillwater-breeding amphibian species move upland during summer, when herbicide application to control weeds in aquatic habitats typically occurs. However, aquatic weed management may pose a risk for aquatic species present in wetlands through the summer, such as the Oregon spotted frog (OSF, Rana pretiosa), a state endangered species in Washington. Acute toxicity of herbicides used to control aquatic weeds tends to be low, but the direct effects of herbicide tank mixes on OSFs have remained unexamined. We exposed juvenile OSFs to tank mixes of the herbicide imazapyr, a surfactant, and a marker dye in a 96-h static-renewal test. The tank mix was chosen because of its low toxicity to fish and its effectiveness in aquatic weed control. Concentrations were those associated with low-volume (3.5 L/ha) and high-volume (7.0 L/ha) applications of imazapyr and a clean-water control. Following exposure, frogs were reared for two months in clean water to identify potential latent effects on growth. Endpoints evaluated included feeding behavior, growth, and body and liver condition indices. We recorded no mortalities and found no significant differences for any end point between the herbicide-exposed and clean-water control frogs. The results suggest that imazapyr use in wetland restoration poses a low risk of direct toxic effects on juvenile OSFs. Copyright © 2012 SETAC.

    2000-01-01

    We studied first-year movements of Mexican Spotted Owls (Strix occidentalis lucida) during natal dispersal in canyonlands of southern Utah. Thirty-one juvenile Mexican Spotted Owls were captured and radiotracked during 1992-95 to examine behavior and conduct experiments related to the onset of natal dispersal. Juvenile Spotted Owls dispersed from their nest areas during September to October each year, with 85% leaving in September. The onset of movements was sudden and juveniles dispersed in varied directions. The median distance from nest area to last observed location was 25.7 km (range = 1.7-92.3 km). Three of 26 juveniles tracked (11%) were alive after one year, although none were observed with mates. We conducted a feeding experiment, using Mongolian gerbils (Meriones unguicuculatus), to test the influence of increased food supply on dispersal onset. The mean dispersal date of five owls that received supplemental food (Julian day no. 255 ?? 2.6 SD) was significantly different than a control group (day no. 273 ?? 12.3).

    This illustrated article represents a popular account of the study of the Babylonian astronomical records of Enuma Anu Enlil tablet series i.e. of the Venus Tablet of Ammisaduqa and of two lunar eclipses linked with the IIIrd dynasty of Ur, having resulted in the proposal of Ultra-Low chronology of the Near East in II millennium B.C. The emerged Ultra-Low chronology is by 96 years shorter than the conventional Middle chronology and by now is supported by various independent studies. Tables of relative chronologies of principal kingdoms of Mesopotamia are given, along with some dates associated with the fall of Babylon in II millennium B.C. The technical details are given in the book by H.Gasche, J.A.Armstrong, S.W.Cole and V.G.Gurzadyan, "Dating the Fall of Babylon" (Mesopotamian History and Environment, Series II, University of Ghent and Chicago Press, 1998) and in subsequent articles.

    Full Text Available Partial characterizations of digestive proteases were studied in three life stages of spotted rose snapper: early (EJ, middle (MJ and late juvenile (LJ with corresponding average weights of 21.3 ± 2.6 g (3 months after hatching, MAH, 190 ± 4.4 g (7 MAH, and 400 ± 11.5 g (12 MAH. At sampling points, the digestive tract was dissected into the stomach (St, pyloric caeca (PC, and the intestine in three sections (proximal (PI, middle (MI and distal intestine (DI. The effect of pH and temperature and specific inhibitors were evaluated for acid and alkaline proteases. Total acid and alkaline protease activity showed a tendency to increase with juvenile life stage of fish while trypsin activity decreased. Differences were found in acid and alkaline protease activities at different pH and temperatures during juvenile stages. Pepstatin A inhibited total activity in the stomach extract in all juvenile stages. Activity in total alkaline protease inhibition was significantly higher in EJ using TLCK, PMSF, SBTI, Phen and Ovo than in MJ and LJ, while no significant differences were found with TPCK inhibition. Therefore increases in protease activities with fish growth through juvenile stages in which a substitution or diversification in the type of alkaline enzymes exist. These results lead a better comprehension of changes in digestive potential of Lutjanidae fish.

    We observed the osteological development of larval and juvenile red spotted grouper (Epinephelus akaara) in order to generate data for the assessment of skeletal deformities and to inform phylogenetic systematics research. Larvae and juveniles were obtained from a aquafarm in Muan-gun, Jeolla-namdo Province, Korea. The average water temperature at the time of breeding was 23.0°C and average water salinity was 33.0 psu. Freshly hatched fish larvae had not undergone any ossification, but ossification of the parasphenoid bone, which forms the base of the cranium, occurred as the juveniles reached an average body length (BL) of 2.49 mm. At the same time, ossification of the preopercle and opercle occurred in the operculum, and ossification of the maxilla, which forms the upper jaw, and the dentary bones, which form the lower jaw, began. In addition, ossification of the vertebra occurred by formation of 7 vertebral centra and the neural spine in the abdominal vertebra. When the juveniles reached an average (BL) of 5.22 mm, ossification of the nasal, lateral ethmoid, and alisphenoid bones occurred in the cranium; ossification of the endopterygoid and metapterygoid bones began in the palatine region; and ossification of the hypohyal and interhyal bones occurred in the hyoid arch. At an average (BL) of 20.9 mm, ossification of the basisphenoid bone in the cranium and the suborbital bone in the orbital region occurred. Ossification of the vertebra then occurred by the formation of long pairs of ribs from the third to the ninth abdominal vertebrae, completing osteological development.

    As some literature on the susceptibility of different life stages of Macrobrachium rosenbergii to white spot syndrome virus (WSSV) is conflicting, the pathogenesis, infectivity and pathogenicity of 2 WSSV strains (Thai-1 and Viet) were investigated here in juveniles using conditions standardized for Penaeus vannamei. As with P. vannamei, juvenile M. rosenbergii (2 to 5 g) injected with a low dose of WSSV-Thai-1 or a high dose of WSSV-Viet developed comparable clinical pathology and numbers of infected cells within 1 to 2 d post-infection. In contrast, a low dose of WSSV-Viet capable of causing mortality in P. vannamei resulted in no detectable infection in M. rosenbergii. Mean prawn infectious dose 50% endpoints (PID₅₀ ml⁻¹) determined in M. rosenbergii were in the order of 100-fold higher for WSSV-Thai-1 (105.3 ± 0.4 PID₅₀ ml⁻¹) than for WSSV-Viet (103.2 ± 0.2 PID₅₀ ml⁻¹), with each of these being about 20-fold and 400-fold lower, respectively, than found previously in P. vannamei. The median lethal dose (LD₅₀ ml⁻¹) determined in M. rosenbergii was also far higher (~1000-fold) for WSSV-Thai-1 (105.4 ± 0.4 LD₅₀ ml⁻¹) than for WSSV-Viet (102.3 ± 0.3 LD₅₀ ml⁻¹). Based on these data, it is clear that juvenile M. rosenbergii are susceptible to WSSV infection, disease and mortality. In comparison to P. vannamei, however, juvenile M. rosenbergii appear more capable of resisting infection and disease, particularly in the case of a WSSV strain with lower apparent virulence.

    We estimated natural mortality rates (M) of age-1 Spot Leiostomus xanthurus by using a sonic telemetry approach. Sonic transmitters were surgically implanted into a total of 123 age-1 Spot in two North Carolina estuarine creeks during spring 2009 and 2010, and the fish were monitored by using a stationary acoustic receiver array and manual tracking. Fates of telemetered Spot were inferred based on telemetry information from estimated locations and swimming speeds. Potential competitors of age-1 Spot were assessed through simultaneous otter trawl sampling, while potential predators of Spot were collected using gill nets and trammel nets. The number of inferred natural mortalities was zero in 2009 (based on 29 telemetered Spot at risk) and four in 2010 (based on 52 fish at risk), with fish being at risk for up to about 70 d each year. Catches of potential competitors or predators did not differ between years, and age-1 Spot were not found in analyzed stomach contents of potential predators. Our estimated 30-d M of 0.03 (95% credible interval = 0.01–0.07) was lower than that predicted from weight-based (M = 0.07) and life-history-based (M = 0.06–0.36) estimates. Our field-based estimate of M for age-1 Spot in this estuarine system can assist in the assessment and management of Spot by allowing a direct comparison with M-values predicted from fish size or life history characteristics. The field telemetry and statistical analysis techniques developed here provide guidance for future telemetry studies of relatively small fish in open, dynamic habitat systems, as they highlight strengths and weaknesses of using a telemetry approach to estimate M.

    This study was conducted in order to examine the egg development in red spotted grouper, Epinephelus akaaraand the morphological development of its larvae and juveniles, and to obtain data for taxonomic research. This study was conducted in June 2013, and 50 male and female fish were used for the study. One hundred μg/kg of LHRHa was injected into the body of the fish for inducing spawning, and the fish were kept in a small-sized fish holder (2×2×2 m). Eggs were colorless transparent free pelagic eggs, 0.71-0.77 mm large (mean 0.74±0.02 mm, n=30), and had an oil globule. Hatching started within 27 h after fertilization. Pre-larvae that emerged just after hatching were 2.02-2.17 mm in total length (mean 2.10±0.11 mm), their mouth and anus were not opened yet, and the whole body was covered with a membrane fin. Post-larvae that emerged 15 days post hatching were 3.88-4.07 mm in total length (mean 3.98±0.13 mm), and had a ventral fin with two rays and a caudal fin with eight rays. Juveniles that were formed at 55 d post hatching, were 31.9-35.2 mm in total length (mean 33.6±2.33 mm), with red color deposited over the entire body, and black chromophores deposited in a spotted pattern. The number of fin rays, body color, and shape were the same as that in the adult fish.

    Effects of water temperature (17, 21, 25, 30 and 35°C) and body size (14.75-281.41 g initial body weight) on food consumption, growth, feed conversion, and dry matter content in orange-spotted grouper fed to satiation were investigated. The combined effect of temperature ( T, °C) and body weight ( W, g) on maximum food consumption ( C max, g/day) was described as: ln C max=-7.411+0.828 ln W+0.317 T-0.004 7 T 2, and the optimum feeding temperature was 33.9°C. The combined effect of temperature and body weight on growth ( G) was described as: ln G=-4.461-0.208ln W+0.394 T-0.006 3 T 2. The optimum growth temperature was 31.4°C, whereas overall growth rates were high at 25, 30 and 35 °C. Feed conversion efficiencies ( FCE, %), increasing first and then decreasing with increasing temperature, averaged from 1.8 to 2.1 in terms of dry weight of food fish. The optimum temperature for FCE tended to be lower than that for growth or feeding. Dry matter content increased with both increasing water temperature (17, 25, 30 and 35°C) and body weight, and the combined effect of temperature and body weight on dry matter content ( DM, %) was described as: ln DM=3.232+0.01 4 ln W-0.004 4 T+0.001 2 Tln W.

    Full Text Available In this study, the extract of Spirulina platensis were examined in vitro to inhibit white spot syndrome virus (WSSV and application of dry S. platensis in diet for prevention of white spot syndrome (WSS in post larvae and juvenile black tiger shrimp (Penaeus monodon. The results showed that the lowest concentration of the extract for inhibiting WSSV was 0.01 mg/ml, while the optimum concentration was found to be 0.1 mg/ ml in which the mortality rate of the shrimp was 4 percents and infection was not detected from survivalshrimp by the immunohistochemistry method.Furthermore, The results showed that the survival rate of the post larvae fed on steamed egg containing dry S. platensis 5 g/kg of diet was higher than that of the control (p<0.05 when challenged with WSSV and no WSSV infected shrimp examine by polymerase chain reaction (PCR assay. In the case of juvenile shrimp, the survival rate of shrimp fed pellets containing dry S. platensis 10 g/kg of diet was higher than that of the control group (p<0.05 after challenging with WSSV. Moreover percent of WSSV infection in the survival shrimp using the immunohistochemistry method was lower than that of the control group.

    Full Text Available Skeletal deformity is a significant problem in fish culture. The skeletal deformities in red spotted grouper from yolk-sac to juvenile stages were examined through clearing and staining of the cartilage and bone using Alcian Blue and Alizarin Red S. The overall results showed that the pattern of incidence of deformities showed an increase from preflexion to juvenile stages. The rate of deformities based on ten elements of bone from preflexion to juvenile stages were as follows: vertebral (42.6%—9.0%, dorsal proximal radials (4.8%—25.2%, neural spine (0%—8.4%, haemal spine (0%—6.8%, hypural (1.3%—5.4%, anal proximal radials (0%—5.4%, epural (1.3%—4.9%, arypural (2.0%—4.5%, lower jaw (1.3%—2.5%, and upper jaw (0%. Vertebral and dorsal proximal radials were recognized as the most susceptible parts to deformation. The main types of bone deformity were lordosis, scoliosis, fusion, shortening, branching, supernumerary elements, and saddleback syndrome. Development of saddleback syndrome was detected initially in preflexion stage, which was accompanied by deformity of the neural spines, dorsal proximal radials, and disposition of the distal radials and dorsal spines in later life stages. The skeletal deformity encountered during the larval rearing period could be caused by water surface tension.

    White spot syndrome virus (WSSV) is the most catastrophic pathogen the shrimp industry has ever encountered. VP28, the abundant envelope protein of WSSV was expressed in bacteria, the purified protein administered orally to Penaeus monodon juveniles and its immune modulatory effects examined. The results indicated significant up-regulation of caspase, penaeidin, crustin, astakine, syntenin, PmRACK, Rab7, STAT and C-type lectin in animals orally administered with this antigen. This revealed the immune modulations in shrimps followed by oral administration of rVP28P which resulted in the reduced transcription of viral gene vp28 and delay in mortality after WSSV challenge. The study suggests the potential of rVP28P to elicit a non-specific immune stimulation in shrimps.

    In this study, the developmental expression pattern of myostatin (mstn) in the spotted rose snapper Lutjanus guttatus under culture conditions is presented. The full coding sequence of mstn from L. guttatus was isolated from muscle tissue, obtaining 1134 nucleotides which encode a peptide of 377 amino acids. The phylogenetic analysis indicated that this sequence corresponds to mstn-1. mstn expression was detected in embryonic stages, and maintained at low levels until 28 days post-hatch, when it showed a significant increase, coinciding with the onset of metamorphosis. After that, expression was fluctuating, coinciding probably with periods of rapid and slow muscle growth or individual growth rates. mstn expression was also analysed by body mass with higher levels detected in smaller animals, irrespective of age. mstn was also expressed in other tissues from L. guttatus, presenting higher levels in brain, eye and gill. In brain for instance, two variants of mstn were isolated, both coding sequences were identical to muscle, except that one of them contained a 75 nucleotide deletion in exon 1, maintaining the reading frame but deleting two conserved cysteine residues. Phylogenetic analysis indicated that this brain variant was also mstn-1. The function of this variant is not clear and needs further investigation. These results indicate that mstn-1 participates in different physiological processes other than muscle growth in fishes.

    White spot syndrome virus (WSSV), a rod-shaped double-stranded DNA virus, is an infectious agent causing fatal disease in shrimp farming around the globe. Within shrimp populations WSSV is transmitted very fast, however, the modes and dynamics of transmission of this virus are not well understood. In the current study the dynamics of disease transmission of WSSV were investigated in small, closed populations of Penaeus monodon and Penaeus vannamei. Pair cohabitation experiments using PCR as a readout for virus infection were used to estimate transmission parameters for WSSV in these two species. The mortality rate of contact-infected shrimp in P. monodon was higher than the rate in P. vannamei. The transmission rate parameters for WSSV were not different between the two species. The relative contribution of direct and indirect transmission rates of WSSV differed between the two species. For P. vannamei the direct contact transmission rate of WSSV was significantly lower than the indirect environmental transmission rate, but for P. monodon, the opposite was found. The reproduction ratio R0 for WSSV for these two species of shrimp was estimated to be above one: 2.07 (95%CI 1.53, 2.79) for P. monodon and 1.51 (95%CI 1.12, 2.03) for P. vannamei. The difference in R0 between the two species is due to a lower host mortality and hence a longer infectious period of WSSV in P. monodon.

    Full Text Available The feasibility of replacing fish meal protein at different levels with poultry by product meal food grade (PBM-FG was assessed in diets for spotted rose snapper Lutjanus guttatus. Four diets were formulated, the control diet fish meal was used as the main protein source (FM; the other three diets had increasing levels of PBM-FG replacing 25, 50 or 75% of the fish meal protein respectively. The diets were fed close to apparent satiation, three times a day to quadruplicate groups of juvenile snapper (average body weight 11.0 ± 0.04 g. The fish were randomly distributed into groups of 15 fish in a 120 L seawater tank. The response of snapper to diets containing graded levels of fish meal was evaluated by measuring weight gain, feed efficiency, body composition, hematological parameters and apparent nutrient digestibility during a 12-week period. The replacing of the 25% of fish meal protein by PBM-FG did show a similar trend for feed efficiency and growth performance than control diet. Feed efficiency and growth performance was reduced at 75% level of fish meal protein replacement by PBM-FG, due to deficiencies of lysine and methionine. The final whole-body proximate composition did not differ among treatments. The hematological characteristics were similar among the treatments control, 25 and 50%, but the fish fed PBM-FG 75% showed the lowest levels for total protein and glucose parameters. The dietary dry matter and protein apparent digestibility coefficients (ADCs decreased with increasing dietary PBM-FG. High values for lipid ADCs were observed in all diets.

    The traditional date of 1595 BCE for the destruction of Babylon by the Hittite king Mursili I is accepted by most historians for many years despite notable controversies. This pivotal date is considered crucial to the various calculations of the early chronology of the ancient Near East. According to the Venus Tablet (Enuma Anu Enlil 63) which describes the rising and setting of Venus during the reign of Ammisaduqa, there are only 4 possibilities implying 4 dates for the destruction of Ur (1912, 1944, 2004, 2064 BCE) but a tablet of astronomical omens (Enuma Anu Enlil 20,21) mentions a lunar eclipse, dated 14/III/48, at the end of the reign of Shulgi and a lunar eclipse, dated 14/XII/24, at the end of the reign of Ibbi-Sin. Over the period 2200-1850 BCE there are only 3 pairs of eclipses, spaced by 42 years, matching the description of astronomical omens but only 1 agreeing with the previous 4 dates. The second way to check the date for the fall of Babylon is to rebuild the chronology of this period thanks to...

    The first basic step in obtaining a correct geographical knowledge and initiative for archaeological cartography analysis is an adequately geo-localized representation of natural and semi-natural resources and human activities, present and past. In this context, the correct and contextual evaluation of the resources through the use of integrated techniques of aerial photos, remote sensing and geographic information system (GIS) supply the synoptic instrument to the real knowledge of the land geography and for the operational management of any research and project. We will describe, at a synthetic level, the maturity of the land systematic study of Babylon archaeological site using different change detection analysis. Topographic maps of 1920 and 1980 were used, 18 aerial photos (1986) were mosaicked and georeferenced, vector information was digitized and inserted in a GIS system, DTM was build. Object oriented image analysis activity is being carried on and initial results are available through a WebGIS. The use of remote sensing (Quickbird and Ikonos) data allows us to capture the integral mutations due to human interventions. Earth observation data and GIS system were an optimal starting point for generating and updating the cartography. This results will be indispensable for the Iraqi authority and scientific community who care about the future of the territory.

    The effects of Ec-α2MR (Epinephelus coiodes-α2-macroglobulin receptor) on growth performance, enzymatic activity, respiratory burst, MDA level, total antioxidant capacity, DPPH radical scavenging percentage and immune-related gene expressions of the juvenile orange-spotted grouper were evaluated. The commercial diet supplemented with α2MR additive was used to feed the orange-spotted grouper for six weeks. Although a slight increase was observed in the specific growth rate, survival rate and weight gain, no significance was observed among different group. After the feeding trial, the groupers were exposed to cold stress. Respiratory burst activity and MDA level decreased significantly in α2MR additive group by comparing with the control and additive control group, while a sharp increase of ACP activity, ALP activity, total antioxidant capacity and DPPH radial scavenging percentage was observed in α2MR additive group. qRT-PCR analyses confirmed that the up-regulated mRNA expressions of C3, TNF1, TNF2, IL-6, CTL, LysC, SOD1 and SOD2 were observed in α2MR additive group at 20 °C. These results showed that α2MR additive may moderate the immune response in grouper following cold shock challenge.

    Full Text Available The author argues that the earliest recension of the Slavonic Aḥiqar (Povestʹ ob Akire Premudrom was produced in Bulgaria as a direct translation from Syriac, whereas the original Christian (Syriac recension was created in the Syriac-speaking anti-Chalcedonian milieu within the Sassanid Iranian Empire in the late fifth century; in this latter context, it originated as a hagiographic legend inaugurating a new cult directed against the pro-Chalcedonian Ctesiphon cult of the Three Youths in Babylon. This anti-Chalcedonian and anti-Byzantine work was never accepted in Byzantine culture.

    Directory of Open Access Journals (Sweden)

    Andrew Hurley

    2011-09-01

    Full Text Available Hubertus Siegert’s impressionistic documentary, Berlin Babylon, illuminates the demolition and urban renewal of Berlin during the mid-late 1990s. This was a critical phase in the city’s history, as it prepared, amidst a flurry of excitement and anticipation, to become the united Germany's seat of power. Siegert's film seeks to give pause for thought, but deliberately eschews a “voice of god” voiceover, opting instead for a poetic audiovisual montage. This includes shots of the cityscape (and its lacunae, archival footage documenting the wartime devastation and subsequent dynamiting of buildings, observational cinema of the city’s busy building sites, and of verbal snippets from various architects, developers and politicians––following the film title’s cue, the agents in a rerun of the construction of the Tower of Babel––as well as epigraphs from the Bible and Walter Benjamin, and a prominent soundscape and musical score. As this article will demonstrate, the film’s (mostly sombre soundtrack plays a critical role here, commenting on the footage, and beyond that on the whole project of the new ‘Berlin Republic’ and its attitude to architectural heritage and twentieth century history. Re-figuring the theme of this volume, Berlin Babylon’s music is a form of writing about (collapsing, old architecture and history. And yet, the soundtrack is not as unambiguous as a voiceover might have been, and thereby allows creative space for the audience’s interpretation, a matter that was very important to the film’s director. This article will focus, in particular, on three elements: the use (and treatment of historical recordings in the film; the use of silence; and finally the way in which tracks from the Berlin band Einstürzende Neubauten use music, noise and text to comment on the project of the new Berlin.

    Aquaculture production efficiency may increase by using feed additives. This study investigated the effects of diff erent dietary additives [w/w: 2% small peptides, 0.01% probiotics (Bacillus licheniformis) and 0.2% prebiotics (inulin)] on growth performance, digestive enzyme activities, and oxidative stress in juvenile Epinephelus coioides reared in artificial seawater of two salt concentrations (13.5 vs. 28.5). Weight gain rate was significantly higher in fish fed the diet supplemented with small peptides, B. licheniformis, inulin, or synbiotics than that in fish fed the basal diet; the greatest weight gain rate was found in fish fed the small peptide treatment [56.0% higher than basal diet]. Higher feed efficiency was detected in fish fed the diet supplemented with small peptides than that of fish in the other dietary treatments. Total protease activity in the stomach and intestines was highest in fish fed the small peptide-treated diet, whereas lipase activity was highest in those fed synbiotics (combination of Bacillus licheniformis and inulin) than that in fish fed the other treatments. Antioxidant enzyme (total superoxide dismutase and catalase) activities and hepatic malondialdehyde content were higher in fish receiving the dietary supplements and maintained in artificial seawater containing 13.5 salinity compared with those in the control (28.5). Hepatic catalase activity in grouper fed the diets with small peptides or synbiotics decreased significantly compared with that in control fish. Overall, the three types of additives improved growth rate of juvenile grouper and digestive enzymes activities to varying degrees but did not effectively improve antioxidant capacity under low-salinity stress conditions.

    The effects of Dissostichus mawsoni-Calmodulin (Dm-CaM) on growth performance, enzyme activities, respiratory burst, MDA level and immune-related gene expressions of the orange-spotted grouper (Epinephelus coioides) exposed to the acute low temperature stress were evaluated. The commercial diet supplemented with Dm-CaM protein was fed to the groupers for 6 weeks. No significant difference was observed in the specific growth rates, weight gains and survivals. After the feeding trial, the groupers were exposed to acute low temperature challenge. The groupers fed with Dm-CaM additive diet showed a significant decrease in the respiratory burst activity, while the blood cell number increased significantly at 25 °C by comparing with the control and additive control group. The enzymatic activity of SOD, ACP and ALP increased significantly in Dm-CaM additive group, while MDA level maintained stable with the lowest value. qRT-PCR analysis indicated that the up-regulated transcript expressions of CaM, C3, SOD2, LysC and HSPA4 were observed in Dm-CaM additive group. These results indicated that Dm-CaM additive diet may regulate the grouper immune response to the acute low temperature challenge.

    Al-Hillah Qadhaa is located in the central part of Iraq. It covers an area of 908 km(2) with a total population of 856,804 inhabitants. This Qadhaa is the capital of Babylon Governorate. Presently, no landfill site exists in that area based on scientific site selection criteria. For this reason, an attempt has been carried out to find the best locations for landfills. A total of 15 variables were considered in this process (groundwater depth, rivers, soil types, agricultural land use, land use, elevation, slope, gas pipelines, oil pipelines, power lines, roads, railways, urban centres, villages and archaeological sites) using a geographic information system. In addition, an analytical hierarchy process was used to identify the weight for each variable. Two suitable candidate landfill sites were determined that fulfil the requirements with an area of 9.153 km(2) and 8.204 km(2) These sites can accommodate solid waste till 2030.

    The report area comprises 270 square miles, and includes most of the Towns of Babylon and Islip, and parts of the Towns of Huntington, Smithtown, and Brookhaven, in southwestern Suffolk County, New York. Almost all the water used in the area is obtained from wells screened in permeable zones of the ground-water reservoir which consists of unconsolidated deposits of gravel, sand, silt, and clay as much as 1,800 feet thick. The ground-water reservoir contains three principal aquifers. From the surface down these are (a) surficial deposits of sand and gravel of Pleistocene age, (b) sands of the Magothy (?) Formation of Cretaceous age, and (c) the Lloyd Sand Member of the Raritan Formation of Cretaceous age. At present only the upper two aquifers are tapped by wells. Natural replenishment of the ground-water reservoir in the area takes place entirely by infiltration of precipitation and averages about 215 mgd (million gallons per day). Average ground-water runoff to streams above tidewater is 114 mgd, and it is estimated that an additional 54 mgd is discharged into tidal reaches of streams. Ground-water evapotranspiration is computed to be about 10 mgd and submarine outflow from the area is estimated to be 18 mgd. The average streamflow of the area above tidewater is 120 mgd. Because of the permeable soils and low relief, direct runoff is only about 5 percent of the average streamflow. Streams are perennial along their middle and lower reaches and exhibit well-sustained low flows. Flooding rarely occurs although continued urbanization may result in minor flooding problems as additional storm sewers are constructed. Water in most of the area is generally of good quality; however, it may be contaminated locally. Some streams and parts of the water-table aquifer contain low concentrations of synthetic detergents and other dissolved constituents from domestic and industrial wastes. Salty water occurs in parts of the water-table aquifer in the area under and bordering Great

    The percent weight gain (PWG) and feeding efficiency (FE) of fingerling orange-spotted grouper, Epinephelus coioides, fed diets containing sodium alginate at 1.0 and 2.0 g kg(-1) were calculated on the 2nd, 4th, 6th, and 8th weeks after feeding. Survival rates of the fingerling grouper against Streptococcus sp. and an iridovirus, and non-specific immune parameters such as alternative complement activity (ACH50), lysozyme activity, natural haemagglutination activity, respiratory bursts, superoxide dismutase (SOD) activity, and phagocytic activity of juvenile grouper were also determined when the fish were fed diets containing sodium alginate at 0.5, 1.0, or 2.0 g kg(-1). The PWG and FE of fish were better when the fish were fed diets containing sodium alginate at 1.0, and 1.0 and 2.0 g kg(-1), respectively. The PWG and FE of fish fed the 0, 1.0 and 2.0 g kg(-1) sodium alginate-containing diets after 8 weeks were 271.0%, 454.4% and 327.8%, and 0.61, 0.72 and 0.68, respectively. Fish fed a diet containing sodium alginate at the level of 2.0 g kg(-1) had a significantly higher survival rate than those fed the control diet after challenge with Streptococcus sp. and an iridovirus causing an increase of survival rate by 25.0% and 16.7%, respectively, compared to the control group. The ACH(50) level of fish fed the sodium alginate-containing diets at 2.0 g kg(-1) was significantly higher than those fed the 1.0 g kg(-1) sodium alginate diet and control diet after 12 days, and had increased to 1.9-fold, compared to those fed the control diet. The lysozyme activity, phagocytic activity, respiratory bursts, and SOD level of fish fed the sodium alginate-containing diets at 1.0 and 2.0 g kg(-1) were significantly higher than those fed the control diet after 12 days, and had increased to 1.97- and 1.68-fold, 1.35- and 1.50-fold, 1.63- and 1.81-fold, and 1.23- and 1.31-fold, respectively, compared to those fed the control diet. We therefore recommend dietary sodium alginate

    Juvenile scleroderma is a rare childhood condition characterized by fibrosis of the skin and internal organs. Clinical manifestations of childhood scleroderma are different from adult disease and early recognition, correct classification and treatment can improve long-term outcome. This review explores the most recent actualizations on clinical manifestations, classification criteria, treatment options and prognosis of juvenile scleroderma. There are two main forms of the disease: localized scleroderma and systemic sclerosis. Localized scleroderma is the most common form in children and mostly restricted to the skin. Juvenile diffuse systemic sclerosis is related to visceral involvement and cardiac disease which is the main cause of death in these patients. The outcome of juvenile systemic sclerosis is better compared with the adult form. Treatment remains a medical challenge and the EULAR task force proposed an approach to juvenile scleroderma treatment based on expert's opinion and guidelines used for the treatment of adults. Larger studies on childhood scleroderma are warranted.

    We describe new scenarios for generating curvature perturbations when inflaton (curvaton) has significant interactions. We consider a ''spot'', which arises from interactions associated with an enhanced symmetric point (ESP) on the trajectory. Our first example uses the spot to induce a gap in the field equation. We observe that the gap in the field equation may cause generation of curvature perturbation if it does not appear simultaneous in space. The mechanism is similar to the scenario of inhomogeneous phase transition. Then we observe that the spot interactions may initiate warm inflation in the cold Universe. Creation of cosmological perturbation is discussed in relation to the inflaton dynamics and the modulation associated with the spot interactions.

    2011-01-01

    Full Text Available Introduction. Juvenile myasthenia is a chronic autoimmune neuromuscular disease characterized by varying degrees of fluctuating, painless muscle weakness and rapid fatigue of any muscles under voluntary control. Juvenile myasthenia is a form of myasthenia appearing in adolescent age, representing 10% to 15% of all cases of myasthenia gravis. Juvenile myasthenia is presented by a defect in the transmission of nerve impulses to muscles, resulting from a breakdown in the normal communication between nerves and muscles. In myasthenia, antibodies produced by the body’s own immune system block, alter, or destroy the receptors for acetylcholine. Juvenile myasthenia is neither directly inherited nor is it contagious. Signs and Symptoms. The first noticeable symptoms may be eye muscle weakness, difficulty in swallowing, or slurred speech. Juvenile myasthenia usually affects muscles innervated by the cranial nerves (face, lips, tongue, neck and throat, but it can affect any muscle group. Symptoms vary in type and severity with typical periods of exacerbation interspersed with periods of remission. When the muscles necessary for breathing are affected, a patient is said to be in a myasthenic crisis, which is a life-threatening situation. Disease Outcome and Treatment. Juvenile myasthenia produces sporadic but progressive weakness and abnormal fatigability of striated (skeletal muscles, exacerbated by exercise and repeated movement, but improved by rest and anticholinesterase drugs. Juvenile myasthenia follows an unpredictable course of recurring exacerbations and periodic remissions. With current therapies, however, most cases of juvenile myasthenia are not as serious as the name implies. Although there is no known cure, drug treatment has improved prognosis and allows patients to lead relatively normal lives, except during exacerbations.

    A Spacecraft Position Optimal Tracking (SPOT) program was developed to process Global Positioning System (GPS) data, sent via telemetry from a spacecraft, to generate accurate navigation estimates of the vehicle position and velocity (state vector) using a Kalman filter. This program uses the GPS onboard receiver measurements to sequentially calculate the vehicle state vectors and provide this information to ground flight controllers. It is the first real-time ground-based shuttle navigation application using onboard sensors. The program is compact, portable, self-contained, and can run on a variety of UNIX or Linux computers. The program has a modular objec-toriented design that supports application-specific plugins such as data corruption remediation pre-processing and remote graphics display. The Kalman filter is extensible to additional sensor types or force models. The Kalman filter design is also strong against data dropouts because it uses physical models from state and covariance propagation in the absence of data. The design of this program separates the functionalities of SPOT into six different executable processes. This allows for the individual processes to be connected in an a la carte manner, making the feature set and executable complexity of SPOT adaptable to the needs of the user. Also, these processes need not be executed on the same workstation. This allows for communications between SPOT processes executing on the same Local Area Network (LAN). Thus, SPOT can be executed in a distributed sense with the capability for a team of flight controllers to efficiently share the same trajectory information currently being computed by the program. SPOT is used in the Mission Control Center (MCC) for Space Shuttle Program (SSP) and International Space Station Program (ISSP) operations, and can also be used as a post -flight analysis tool. It is primarily used for situational awareness, and for contingency situations.

    Purpose of review To provide a comprehensive update of the pathogenesis, diagnostic imaging, treatments, and disease activity measurements of juvenile spondyloarthritis (JSpA). Recent findings Genetic and microbiome studies have provided new information regarding possible pathogenesis of JSpA. Recent work suggests that children with JSpA have decreased thresholds for pain in comparison to healthy children. Additionally, pain on physical examination and abnormalities on ultrasound of the entheses are not well correlated. Treatment guidelines for juvenile arthritis, including JSpA, were published by the American College of Rheumatology and are based on active joint count and presence of sacroiliitis. Recent studies have established the efficacy of tumor necrosis factor inhibitors in the symptomatic treatment of axial disease, though their efficacy for halting progression of structural damage is less clear. Newly developed disease activity measures for JSpA include the Juvenile Arthritis Disease Activity Score and the JSpA Disease Activity index. In comparison to other categories of juvenile arthritis, children with JSpA are less likely to attain and sustain inactive disease. Summary Further microbiome and genetic research may help elucidate JSpA pathogenesis. More randomized therapeutic trials are needed and the advent of new composite disease activity measurement tools will hopefully allow for the design of these greatly needed trials. PMID:26002028

    Juvenile xanthogranuloma is a benign cutaneous growth presenting as papules or nodules. It is characterized by an intradermal collection of lipid-laden macrophages and varying degrees of fibroblastic proliferation. We have recently observed two patients with xanthogranulomas: one was found to have a papular type and the second patient had multiple nodular growths. We present these cases, which should be considered in the differential diagnosis of skin nodules.

    Full Text Available Mongolian spots (MS are birthmarks that are present at birth and their most common location is sacrococcygeal or lumbar area. Lesions may be single or multiple and usually involve < 5% total body surface area. They are macular and round, oval or irregular in shape. The color varies from blue to greenish, gray, black or a combination of any of the above. The size varies from few to more than 20 centimetres. Pigmentation is most intense at the age of one year and gradually fades thereafter. It is rarely seen after the age of 6 years. Aberrant MS over occiput, temple, mandibular area, shoulders and limbs may be confused with other dermal melanocytoses and bruises secondary to child abuse, thus necessitating documentation at birth. Although regarded as benign, recent data suggest that MS may be associated with inborn errors of metabolism and neurocristopathies. Mongolian spots usually resolve by early childhood and hence no treatment is generally needed if they are located in the sacral area. However, sometimes it may be required for extrasacral lesions for cosmesis.

    Full Text Available The effect of dietary β-Ο-glucan, vitamin E, and β-carotene supplements in juvenile brown shrimp, Farfantepenaeus californiensis, inoculated with white spot syndrome virus (WSSV was evaluated. Groups of 30 organisms (weighing 1 ± 0.5 g were cultured in 60 L fiberglass tanks and fed daily with β-1.3-glucan (0.1%, vitamin E (0.01%, and β-carotene (0.01% for 23 days; the specimens were then inoculated with WSSV. The antioxidant activity of the enzymes superoxide dismutase (SOD and catalase (CAT were determined in the hepatopancreas and muscle at 0, 1, 6, 12, 24, and 48 h after inoculation. Shrimp fed with β-1.3-glucan, vitamin E, and β-carotene significantly increased SOD activity in the hepatopancreas and muscle at 12 and 24 h post-infection, respectively. Shrimp fed with vitamin E and β-1.3-glucan registered an increment in SOD activity from 12 to 48 h post-infection. Shrimp fed with β-carotene increased SOD activity before infection with WSSV, and shrimp fed with β-1.3-glucan and vitamin E increased CAT activity, also before infection. The CAT activity response in shrimp muscle increased with respect to the control group for all treatments tested from 1 to 6 h after inoculation with WSSV. The highest antioxidant response was registered in shrimp fed with vitamin E. Juvenile shrimp fed with vitamin E and later inoculated with WSSV registered 100% mortality at 72 h, but shrimp fed with β-Ο-glucan and β-carotene showed greater resistance to WSSV, with mortality at 144 h post-infection. This study demonstrated the capacity of juvenile Farfantepenaeus californiensis fed β-Ο-glucan, vitamin E, or β-carotene to increase the antioxidant response before and after viral infection.Se evaluó el efecto de β-1,3-glucano, vitamina E y β-caroteno en la dieta de juveniles de camarón café Farfantepenaeus californiensis inoculados con virus del síndrome de la mancha blanca (WSSV.

  18. Are 'hot spots' hot spots?

    Science.gov (United States)

    Foulger, Gillian R.

    2012-07-01

    The term 'hot spot' emerged in the 1960s from speculations that Hawaii might have its origins in an unusually hot source region in the mantle. It subsequently became widely used to refer to volcanic regions considered to be anomalous in the then-new plate tectonic paradigm. It carried with it the implication that volcanism (a) is emplaced by a single, spatially restricted, mongenetic melt-delivery system, assumed to be a mantle plume, and (b) that the source is unusually hot. This model has tended to be assumed a priori to be correct. Nevertheless, there are many geological ways of testing it, and a great deal of work has recently been done to do so. Two fundamental problems challenge this work. First is the difficulty of deciding a 'normal' mantle temperature against which to compare estimates. This is usually taken to be the source temperature of mid-ocean ridge basalts (MORBs). However, Earth's surface conduction layer is ˜200 km thick, and such a norm is not appropriate if the lavas under investigation formed deeper than the 40-50 km source depth of MORB. Second, methods for estimating temperature suffer from ambiguity of interpretation with composition and partial melt, controversy regarding how they should be applied, lack of repeatability between studies using the same data, and insufficient precision to detect the 200-300 °C temperature variations postulated. Available methods include multiple seismological and petrological approaches, modelling bathymetry and topography, and measuring heat flow. Investigations have been carried out in many areas postulated to represent either (hot) plume heads or (hotter) tails. These include sections of the mid-ocean spreading ridge postulated to include ridge-centred plumes, the North Atlantic Igneous Province, Iceland, Hawaii, oceanic plateaus, and high-standing continental areas such as the Hoggar swell. Most volcanic regions that may reasonably be considered anomalous in the simple plate-tectonic paradigm have been

    通过配制7种含不同水平精氨酸(2.13%、2.42%、2.71%、2.95%、3.20%、3.48%、3.74%干物质)的等氮、等脂的实验饲料,研究精氨酸对斜带石斑鱼(Epinephelus coioides)幼鱼生长、饲料利用和血清一氧化氮合酶等的影响。每组设3个重复,每个重复30尾鱼(7.52±0.02g),饲喂8周。结果显示,饲料精氨酸水平对各组存活率无显著影响(P>0.05);精氨酸水平为2.95%的斜带石斑鱼获得最大增重率和特定生长率,显著高于其他各组(P0.05). However, the weight gain rate and specific growth rate were significantly higher in the 2.95% arginine group than in the other groups (P<0.05). The feed coefficient of the fish fed 2.95% arginine was significantly lower than that of the fish fed 2.13%, 2.42%, or 2.71% arginine (P<0.05). The whole-body protein of the fish fed 3.20% arginine was signifi-cantly higher than that of the fish fed 2.13% arginine (P<0.05). Serum glucose tended to decrease as dietary ar-ginine increased, and was significantly higher in the fish fed 2.13% or 2.42% arginine than in those of the other groups (P<0.05). Total protein and total nitric oxide synthase were significantly higher in the sera of fish fed 2.95% arginine than those in the sera of fish in the other groups (P<0.05). These results indicate that dietary ar-ginine not only promotes growth and body protein synthesis, but also improves the immunity of the grouper. A quadratic regression analysis of the specific growth rate against dietary arginine indicated that the optimum argin-ine level for the maximum growth of the juvenile grouper is 3.06%, corresponding to 6.07% of dietary protein on a dry weight basis.

    Full Text Available Social media applications and their use among students have witnessed dramatic increase in the last decade and data on their effect on students academic performance are inconsistent. The aim of this study was to assess the impact of social media on the academic performance and grades of second year medical students at the College of Medicine, University of Babylon, Iraq. Second year medical students (n=57 completed online questionnaire about the type of social media they use frequently, time spent on these media in hours per day, the reasons for use of these media and the effect of social media on their grades. Students were also asked to provide the cumulative grades of physiology and anatomy courses. Time spent by students on social media and facebook messenger was correlated with combined grades of physiology and anatomy courses. All students have been using facebook and 96.5% have been using facebook messenger. Other popular applications were telegram, instagram and ask.fm. Average time spent on social media was 5.07+/- 2.93 and on facebook messenger was 1.80 +/-1.45 hours per day. Forty-two percent of students reported that social media have positive effect on their academic performance. No correlation has been found between time spent on social media or facebook messenger and students combined grades of physiology and anatomy. To conclude, social media and in particular facebook and facebook messenger are very popular among second year medical students. Time spent on social media seems to have no influence on second year medical students grades and academic performance. [J Med Allied Sci 2016; 6(2.000: 77-83

    This article describes common forensic evaluations requested of juvenile court mental health evaluators. There has been a legal shift toward criminalization of juvenile court, with a greater emphasis on rights, abandonment of the rehabilitative model, and greater movement of adolescents into the adult criminal court. A resulting shift has been the redefinition of juvenile court forensic evaluations toward the specificity of adult forensic work. The challenge for evaluators is to refine their knowledge of the forensic standards and bring knowledge of development, assessment, and diagnosis in juveniles and interview techniques appropriate to juveniles to improve the evaluation and forensic reports.

    Juvenile polyposis syndrome is a rare autosomal dominant syndrome characterized by multiple distinct juvenile polyps in the gastrointestinal tract and an increased risk of colorectal cancer.The cumulative life-time risk of colorectal cancer is 39% and the relative risk is 34.Juvenile polyps have a distinctive histology characterized by an abundance of edematous lamina propria with inflammatory cells and cystically dilated glands lined by cuboidal to columnar epithelium with reactive changes.Clinically, juvenile polyposis syndrome is defined by the presence of 5 or more juvenile polyps in the colorectum,juvenile polyps throughout the gastrointestinal tract or any number of juvenile polyps and a positive family history of juvenile polyposis.In about 50%-60% of patients diagnosed with juvenile polyposis syndrome a germline mutation in the SMAD4 or BMPR1A gene is found.Both genes play a role in the BMP/TGF-beta signalling pathway.It has been suggested that cancer in juvenile polyposis may develop through the so-alled "landscaper mechanism" where an abnormal stromal environment leads to neoplastic transformation of the adjacent epithelium and in the end invasive carcinoma.Recognition of this rare disorder is important for patients and their families with regard to treatment,follow-up and screening of at risk individuals.Each clinician confronted with the diagnosis of a juvenile polyp should therefore consider the possibility of juvenile polyposis syndrome.In addition, juvenile polyposis syndrome provides a unique model to study colorectal cancer pathogenesis in general and gives insight in the molecular genetic basis of cancer. This review discusses clinical manifestations, genetics, pathogenesis and management of juvenile polyposis syndrome.

    We studied the infectious effect of SARS-CoV virus on juvenile and adult Brandt's Vole (Microtus brandtii) by nasal cavity spraying method (CCID50 is 105.7). SARS virus caused serious deaths in adults. The death adults demonstrated hemorrhage from mouth, nasal cavity and intestine, hemorrhageious interstitial pneumonia and gore in liver, spleen and kidney. The survival adults demonstrated local hemorrhagic spot in lung and emphysema, but the other organs showed no pathological abnormality. SARS virus caused no deaths in juveniles, but locomotion of infected juveniles became slower. In the early stage, there was local pneumonia in lung and SARS viruses were isolated from the pathological tissue. Only one control juvenile lived and the infected juvenile showed local pneumonia in lung. The results demonstrated that SARS-CoV infected Brandt's vole seriously and adults were more susceptive to SARS-CoV than juveniles. The Brandt's vole may be a potential animal model for SARS research.

    Heuring, Whitney L; Mathis, Alicia

    2014-10-01

    Learning to use a landmark as a beacon to locate resources is one of the simplest forms of spatial learning. We tested whether landmark learning occurs in a semifossorial salamander that migrates annually to breeding ponds as adults. Juvenile spotted salamanders (Ambystoma maculatum) were tested in square containers with a plastic feeding dish in each corner, and a piece of earthworm was placed in one randomly-chosen dish. For landmark-trained salamanders, a rock was placed beside the dish containing the prey. For control salamanders, the rock was placed beside a randomly selected feeding dish. Each salamander was trained once every 2 days for 30 days. Significantly more landmark-trained salamanders than control salamanders entered the landmark area first, and landmark-trained individuals had faster latencies to enter the landmark area and longer stay-times. These results suggest that spotted salamanders are able to locate resources by associating their positions with landmarks.

    Juvenile mammary papillomatosis is a benign proliferative disease of young patients, generally under 30 years of age. The most frequent clinical presentation is the existence of an elastic and mobile lymph node of the breast. Anatomopathologically, it is characterized because it presents ductal epithelial hyperplasia, sometimes with marked atypia, and there are numerous cysts having different sizes among the findings. It has been associated with an increase in the incidence of breast cancer, both in the patient herself as well as her family. We review the literature on the subject and present the mammographic and ultrasonographic findings of a 22 year old woman diagnosed of juvenile mammary papillomatosis. (Author) 12 refs.

    Reynolds, Edward H; Wilson, James V Kinnier

    2014-09-01

    We here review Babylonian descriptions of neurological and psychiatric disorders, including epilepsy, stroke, psychoses, obsessive compulsive disorder, phobias, psychopathic behaviour, depression and anxiety. Most of these accounts date from the first Babylonian dynasty of the first half of the second millennium BC, within a millennium and a half of the origin of writing. The Babylonians were remarkably acute and objective observers of medical disorders and human behaviour. Their detailed descriptions are surprisingly similar to modern 19th and 20th century AD textbook accounts, with the exception of subjective thoughts and feelings which are more modern fields of enquiry. They had no knowledge of brain or psychological function. Some neuropsychiatric disorders, e.g. stroke or facial palsy, had a physical basis requiring the attention of a physician or asû, using a plant and mineral based pharmacology; some disorders such as epilepsy, psychoses, depression and anxiety were regarded as supernatural due to evil demons or spirits, or the anger of personal gods, and thus required the intervention of the priest or ašipu; other disorders such as obsessive compulsive disorder and psychopathic behaviour were regarded as a mystery. The Babylonians were the first to describe the clinical foundations of neurology and psychiatry. We discuss these accounts in relation to subsequent and more modern clinical descriptions.

    Sexual offending by juveniles accounts for a sizable percentage of sexual offenses, especially against young children. In this article, recent research on female juvenile sex offenders (JSOs), risk factors for offending in juveniles, treatment, and the ways in which these youth may differ from general delinquents will be reviewed. Most JSOs do not go on to develop paraphilic disorders or to commit sex offenses during adulthood, and as a group, they are more similar to nonsexual offending juvenile delinquents than to adult sex offenders. Recent research has elucidated some differences between youth who commit sex offenses and general delinquents in the areas of atypical sexual interests, the use of pornography, and early sexual victimization during childhood.

    Full Text Available Abstract Background Trunk asymmetry (TA is a common phenomenon in children, but its incidence in juveniles is not known. The present cross sectional study reports TA in normal juveniles and provides data which describe the evolution of TA from early childhood to adolescence. Materials and methods The scoliometer readings in both standing and sitting forward bending position (FBP of 3301 children, (1645 boys, and 1656 girls aged from 3 to 9 years old were studied. TA was quantified by measuring angle of trunk rotation (ATR and children were categorized as symmetric (ATR = 0°, mild asymmetric (ATR 1° – 6° and severely asymmetric (ATR ≥ 7°. The difference of TA between standing and sitting FBP as well as differences between boys and girls in frequency of TA were also calculated. The scoliometer readings were analyzed by age to reveal at which age the juvenile pattern of TA changes into the adolescent one. Results 74.2% of boys and 77% of girls were symmetric (ATR = 0° in the thoracic region in standing FBP, while 82.7% of boys and 84.1% of girls were symmetric in the thoracic region in sitting FBP. Juvenile girls are more symmetric than boys but severe TA was found almost the same between the two genders. A significant reduction in the frequency of mild TA from standing into sitting FBP, in all the examined regions in both boys and girls was found, but in severe TA this reduction is very small. Analysing scoliometer readings by age it appears that significant TA changes take place between 8–9 years of age for boys and between 6–7 and 8–9 years for girls. TA in boys is changing into the adolescent pattern at a later age than in girls. Conclusion Juveniles were found more symmetric than adolescents, who were studied previously in a different study. Furthermore, juvenile girls were found more symmetric than boys. Juvenile TA pattern seems to be in accordance with the higher incidence of juvenile idiopathic scoliosis in boys. Furthermore

  13. Juvenile Incarceration and Health.

    Addressing the health status and needs of incarcerated youth represents an issue at the nexus of juvenile justice reform and health care reform. Incarcerated youth face disproportionately higher morbidity and higher mortality compared to the general adolescent population. Dental health, reproductive health, and mental health needs are particularly high, likely as a result of lower access to care, engagement in high-risk behaviors, and underlying health disparities. Violence exposure and injury also contribute to the health disparities seen in this population. Further, juvenile incarceration itself is an important determinant of health. Juvenile incarceration likely correlates with worse health and social functioning across the life course. Correctional health care facilities allow time for providers to address the unmet physical and mental health needs seen in this population. Yet substantial challenges to care delivery in detention facilities exist and quality of care in detention facilities varies widely. Community-based pediatricians can serve a vital role in ensuring continuity of care in the postdetention period and linking youth to services that can potentially prevent juvenile offending. Pediatricians who succeed in understanding and addressing the underlying social contexts of their patients' lives can have tremendous impact in improving the life trajectories of these vulnerable youth. Opportunities exist in clinical care, research, medical education, policy, and advocacy for pediatricians to lead change and improve the health status of youth involved in the juvenile justice system.

    The present invention relates to compositions and methods for modulating the juvenile to adult developmental growth transition in plants, such as grasses (e.g. maize). In particular, the invention provides methods for enhancing agronomic properties in plants by modulating expression of GRMZM2G362718, GRMZM2G096016, or homologs thereof. Modulation of expression of one or more additional genes which affect juvenile to adult developmental growth transition such as Glossy15 or Cg1, in conjunction with such modulation of expression is also contemplated. Nucleic acid constructs for down-regulation of GRMZM2G362718 and/or GRMZM2G096016 are also contemplated, as are transgenic plants and products produced there from, that demonstrate altered, such as extended juvenile growth, and display associated phenotypes such as enhanced yield, improved digestibility, and increased disease resistance. Plants described herein may be used, for example, as improved forage or feed crops or in biofuel production.

    In recent experiments, clear transitions in velocity and trail width of an arc spot initiated on nanostructured tungsten were observed on the boundary of the thick and thin nanostructured layer regions. The velocity of arc spot was significantly decreased on the thick nanostructured region. It was suggested that the grouping decreased the velocity of arc spot. In this study, we try to explain the phenomena using a simple random walk model that has properties of directionality and self-avoidance. And grouping feature was added by installing an attractive force between spot cells with dealing with multi-spots. It was revealed that an entanglement of arc spot cells decreased the spot velocity, and spot cells tend to stamp at the same location many times.

    The Information, Education and Communication (IEC) Center of the State Information Service was established in 1979 for the purpose of providing information to the people on the population issue. The Ministry of Information has accorded the State Information Service free TV and radio air time for family planning dramas and spots. In the early years information campaigns were organized to make people aware of the population problem by slogans, songs, and cartoons. Around 1984 misconceptions about family planning and contraceptives were attacked through a number of TV and radio spots. A few years later 21 spots on specific contraceptive methods were broadcast which were aired for three years over 3000 times. They were extremely successful. The impact of these TV spots was one of the major reasons why the contraceptive prevalence rate increased from 30% in 1984 to 38% in 1988 and 47% in 1992. Spots were also broadcast about the social implications of large families. The TV soap opera "And The Nile Flows On", with the family planning message interwoven into it, was very well received by the target audience. A program entitled "Wedding of the Month" features couples who know family planning well. The most successful radio program is a 15-20 minute long quiz show for residents of the villages where the Select Villages Project is being implemented. The State Information Service has 60 local information centers in the 26 governorates of Egypt that make plans for the family planning campaign. In 1992 the Minya Initiative, a family planning project was implemented in the Minya Governorate. As a result, the contraceptive prevalence rate rose from 22% to 30% over 18 months. A new project, the Select Village Project, was developed in 1993 that replicates the Minya Initiative on the village level in other governorates. This new project that was implemented in sixteen governorates.

    The propagation of hard-branch cuttings of tetraploid Robinia pseudoacacia (black locust) is restricted by the low rooting rate; however, etiolated juvenile tetraploid black locust branches result in a significantly higher rooting rate of cuttings compared with non-etiolated juvenile tetraploid branches. To identify proteins that influence the juvenile tetraploid branch rooting process, two-dimensional electrophoresis (2-DE) and matrix-assisted laser desorption/ionization time-of-flight/time-of-flight mass spectra (MALDI-TOF/TOF-MS) were used to analyze proteomic differences in the phloem of tetraploid R. pseudoacacia etiolated and non-etiolated juvenile branches during different cutting periods. A total of 58 protein spots differed in expression level, and 16 protein spots were only expressed in etiolated branches or non-etiolated ones. A total of 40 highly expressed protein spots were identified by mass spectrometry, 14 of which were accurately retrieved. They include nucleoglucoprotein metabolic proteins, signaling proteins, lignin synthesis proteins and phyllochlorin. These results help to reveal the mechanism of juvenile tetraploid R. pseudoacacia etiolated branch rooting and provide a valuable reference for the improvement of tetraploid R. pseudoacacia cutting techniques.

Se dirige al cuerpo electoral a través de la televisión y de Internet, y presenta, en muchos casos, un planteamiento negativo, albergando mensajes destinados a la crítica frontal contra el adversario, más que a la exposición de propuestas propias. Este artículo se centra en el análisis del spot electoral negativo, en aquellas producciones audiovisuales construidas sin más causa que la reprobación del contrincante. Se trata de vídeos que, lejos de emplearse en difundir las potencialidades de la organización y las virtudes de su candidato –además de su programa electoral–, consumen su tiempo en descalificar al oponente mediante la transmisión de mensajes, muchas veces, ad hominem. Repasamos el planteamiento negativo del spot electoral desde su primera manifestación, que en España data de 1996, año de emisión del conocido como vídeo del dóberman, sin olvidar otros ejemplos que completan el objeto de estudio.

    Juvenile ultracool dwarfs are late spectral type objects (later than ~M6) with ages between 10 Myr and several 100 Myr. Their age-related properties lie intermediate between very low mass objects in nearby star-forming regions (ages 1-5 Myr) and field stars and brown dwarfs that are members of the disk population (ages 1-5 Gyr). Kinematic associations of nearby young stars with ages from ~10-100 Myr provide sources for juvenile ultracool dwarfs. The lowest mass confirmed members of these groups are late-M dwarfs. Several apparently young L dwarfs and a few T dwarfs are known, but they have not been kinematically associated with any groups. Normalizing the field IMF to the high mass population of these groups suggests that more low mass (mainly late-M and possibly L dwarf) members have yet to be found. The lowest mass members of these groups, along with low mass companions to known young stars, provide benchmark objects with which spectroscopic age indicators for juvenile ultracool dwarfs can be calibrated and...

    The turbulent spot propagation process in boundary layer flows of air, nitrogen, carbon dioxide, and air/carbon dioxide mixtures in thermochemical nonequilibrium at high enthalpy is investigated. Experiments are performed in a hypervelocity reflected shock tunnel with a 5-degree half-angle axisymmetric cone instrumented with flush-mounted fast-response coaxial thermocouples. Time-resolved and spatially demarcated heat transfer traces are used to track the propagation of turbulent bursts within the mean flow, and convection rates at approximately 91, 74, and 63% of the boundary layer edge velocity, respectively, are observed for the leading edge, peak, and trailing edge of the spots. A simple model constructed with these spot propagation parameters is used to infer spot generation rates from observed transition onset to completion distance. Spot generation rates in air and nitrogen are estimated to be approximately twice the spot generation rates in air/carbon dioxide mixtures.

    The aim of this study was to determine oxidative stress parameters in the liver, gill and muscle of silver catfish juveniles infected with Ichthyophthirius multifiliis and maintained at pH 5.0 or 7.0 for three days. Juveniles were infected by adding one I. multifiliis-infected juvenile and water containing theronts to tanks. After the appearance of white spots on the skin, infected juveniles exposed to pH 5.0 and 7.0 showed significantly higher thiobarbituric acid reactive substances (TBARS) levels in the liver and gills compared to uninfected juveniles. Liver of infected juveniles exposed to pH 7.0 showed higher catalase (CAT) and lower glutathione-S-transferase (GST) activities, but those maintained at pH 5.0 showed significantly higher GST activity than uninfected juveniles. The gills of infected juveniles showed significantly higher CAT (day two) and GST activity at both pH 5.0 and 7.0 compared to uninfected juveniles. Muscle of infected juveniles showed significantly lower CAT and GST activity and TBARS levels (at day three) when maintained at both pH 5.0 and 7.0 compared to uninfected juveniles. In conclusion, I. multifiliis infection induces liver and gill damage via lipid peroxidation products in silver catfish, but higher antioxidant enzyme activity could indicate a greater degree of protection against this parasite.

    Full Text Available Abstract Background Microarray data must be normalized because they suffer from multiple biases. We have identified a source of spatial experimental variability that significantly affects data obtained with Cy3/Cy5 spotted glass arrays. It yields a periodic pattern altering both signal (Cy3/Cy5 ratio and intensity across the array. Results Using the variogram, a geostatistical tool, we characterized the observed variability, called here the spotting effect because it most probably arises during steps in the array printing procedure. Conclusions The spotting effect is not appropriately corrected by current normalization methods, even by those addressing spatial variability. Importantly, the spotting effect may alter differential and clustering analysis.

Most of priestesses dedicated to gods, and mostly lived in the temple, engaging themselves with religious activities. They usually could not get married, and had no offspring; naturally how to spend the old age was a major problem that these priestesses must face. According to historical records, we find that there were four models to support their life in old age:depending on brothers, adopting sons, receiving property from their parents and relying on their own economic income. Priestesses managed to support their life in old age by a variety of efficient ways.

    The association between juvenile arthritis and uveitis is reviewed. Some children with the HLA-B27 related spondyloarthropathies develop anterior uveitis. About 20% of patients with juvenile rheumatoid arthritis (JRA) who are negative for IgM rheumatoid factor develop a frequently bilateral, nongranulomatous chronic anterior uveitis. Risk factors for uveitis in JRA patients are: female gender, pauciarticular onset of arthritis, presence of circulating antinuclear antibodies, and the antigens HLA-DW5 and HLA-DPw2. Uveitis is rare after seven years or more have elapsed from the onset of arthritis. The visual prognosis in patients with uveitis is good in 25% and fair in 50%. The remaining 25% develop visual impairment from complicated cataract and/or secondary inflammatory glaucoma. The potential benefit of cytotoxic agents in the treatment of intractable uveitis is outweighed by the risk of serious side effects. The management of secondary inflammatory glaucoma is unsatisfactory, but the results of treatment of complicated cataracts by lensectomy-vitrectomy are good.

    Aggressive juvenile fibromatosis of the jawbones is a rare tumor presenting as infiltrative mass with unpredictable evolution. We report herein a 17-year-old student with a 6-month history of radiologically proven resorption of a part of the mandible, lingual displacement of tooth 34 and malocclusion. Alveolar ridge resorption and three dark-brown foci in the bone were seen after the tooth was extracted. Histological study showed the tumor tissue to have a bundle-like structure; immunohistochemically it was positive for vimentin, smooth muscle actin, beta-catenin, Ki-67 (5%), and negative for desmin and cytokeratin 34bE12. The golden standard in the diagnostics of desmoid fibromatoses is the nuclear or membrane expression of beta-catenin, which is found in 90% of the cases. Differential diagnosis include mandibular fibroma, well-differentiated fibrosarcoma, fibrosing histiocytoma, and infiltration from adjacent soft-tissue tumor. Aggressive juvenile fibromatosis should be managed by radical excision. Local recurrences are not rare, but metastases do not develop. In rare cases this type of fibromatosis has been known to regress spontaneously. Aggressive fibromatosis is a diagnostic challenge, since it remains in the grey zone between benign and malignant lesions of the oral cavity.

    As the second century of partnership begins, child psychiatry and juvenile justice face continuing challenges in meeting the mental health needs of delinquents. The modern juvenile justice system is marked by a significantly higher volume of cases, with increasingly complicated multiproblem youths and families with comorbid medical, psychiatric, substance abuse disorders, multiple family and psychosocial adversities, and shrinking community resources and alternatives to confinement. The family court is faced with shrinking financial resources to support court-ordered placement and treatment programs in efforts to treat and rehabilitate youths. The recognition of high rates of mental disorders for incarcerated youth has prompted several recommendations for improvement and calls for reform [56,57]. In their 2000 annual report, the Coalition for Juvenile Justice advocated increased access to mental health services that provide a continuum of care tailored to the specific problems of incarcerated youth [58]. The specific recommendations of the report for mental health providers include the need for wraparound services, improved planning and coordination between agencies, and further research. The Department of Justice, Office of Juvenile Justice and Delinquency Prevention has set three priorities in dealing with the mental health needs of delinquents: further research on the prevalence of mental illness among juvenile offenders, development of mental health screening assessment protocols, and improved mental health services [59]. Other programs have called for earlier detection and diversion of troubled youth from juvenile justice to mental health systems [31,56]. Most recently, many juvenile and family courts have developed innovative programs to address specific problems such as truancy or substance use and diversionary or alternative sentencing programs to deal with first-time or nonviolent delinquents. All youths who come in contact with the juvenile justice system

    The dominancy of semi-wild and hatchery-reared white-spotted charr Salvelinus leucomaenis juveniles was evaluated using pair-wise enclosure tests and field stocking tests. The semi-wild S. leucomaenis originated in a hatchery, being stocked into the test stream as eyed-eggs. In the pair-wise enclosure test, the semi-wild S. leucomaenis dominated the hatchery S. leucomaenis that were of a similar standard length (L(S) ). The semi-wild S. leucomaenis were subordinate to hatchery S. leucomaenis that were > 11% larger in LS . In the field stocking test, the abundance and growth of semi-wild S. leucomaenis was decreased in the presence of larger hatchery S. leucomaenis (14% larger LS ). Taken together, these results suggest that larger hatchery S. leucomaenis ecologically suppress the smaller semi-wild S. leucomaenis. Salvelinus leucomaenis juveniles that are stocked with the intention of supplementing natural populations should be < 10% larger than their wild counterparts at the time of stocking to minimize their competitive advantage. The semi-wild and hatchery S. leucomaenis used in both tests were genetically similar individuals, suggesting that the differences are due to the early rearing environment of either a natural stream or hatchery. The hatchery S. leucomaenis have lower levels of aggression as a result of selection in the hatchery rearing environment. Rearing in a natural stream from the eyed-egg stage is likely to increase their lowered aggression.

    Full Text Available The need for punishment of juveniles occurred from the time when there was no clear line separating them from the adult criminal population. At the same time, the evolution of the juvenile punishment is not in itself involve substantial changes to their criminal status. On the contrary, the status of minors in society did not show serious differences regarding the status of young adults, as well as the adult elderly. On the other hand, on the ground of their punishment is recorded deviations that go in the direction of application of mild corporal punishment. Closing the minor was performed in a physically separate parts of the general penal institutions with the use of a lower degree of restrictions while serving juvenile prison. Due to the different treatment of minors during the evolution of their criminal status leads to their different treatment in comparative law. That is why we are witnessing the existence of numerous differences in the juvenile punishment in some countries in the world. On the European continent there is a wide range of different legal solutions when it comes to punishing juveniles. There are considerable differences in the procedure pronouncing juvenile prison and in particular penal treatment of juveniles in penitentiary institutions. For these reasons, the author has decided to show the basic statutory provisions in the part that relates to the issue of punishment of minors in the legislation of individual countries.

    2013-12-01

    Juvenile myasthenia gravis is a relatively rare autoimmune neuromuscular disorder. The pathophysiology of juvenile myasthenia gravis is similar to that of adult myasthenia gravis, though there remain important differences regarding presentation and therapeutic options. We review the pathophysiology, clinical presentation, and treatment options for juvenile myasthenia gravis. Randomized clinical studies of myasthenia gravis have been carried out primarily in adult populations. As juvenile myasthenia gravis is rare, it has been difficult to collect prospective randomized controlled data to evaluate treatment outcomes and efficacy. A recent retrospective series suggests that, as in adult myasthenia gravis, thymectomy is a viable therapeutic option for selected cases of generalized juvenile myasthenia gravis. This is corroborated by the clinical experience of the authors in a referral center with a cohort of patients affected by juvenile myasthenia gravis over a number of years. Recent studies illustrate that some, but not all, adult research on myasthenia gravis is applicable to children and adolescents with juvenile myasthenia gravis. Adult research can inform pediatric studies, but should not be regarded as a substitute for dedicated research in those populations.

    The nomenclature and classification criteria for arthritis in children should be dealt with initially as separate issues, although they are undoubtedly intertwined. The classification criteria should aim to delineate homogeneous patient populations, yet should be flexible enough to incorporate advances in disease knowledge. It should be recognized that arriving at an international consensus for classification criteria will merely provide a set of operational definitions to facilitate research, and not a set of diagnostic criteria. Indeed the only point to obtaining consensus is to begin a process of systematic ongoing review of the criteria. The labels attached to any of these diseases should facilitate accurate communication. In view of the heterogeneous nature of childhood arthritis, consideration should be given to using a broad umbrella term such as juvenile or childhood arthritis only for communicating with the lay public. Medical nomenclature should be formulated to reflect accurately homogeneous subgroups of arthritis, and should not artificially proscribe a relationship between paediatric and adult disease.

    The new classification of juvenile idiopathic arthritis (JIA) is described in this review. Clinical characteristics divide JIA in to subtypes: systemic, oligoarticular (persistent and extended type), RF-positive and--negative polyarticular, enthesitis-related arthritis and psoriatic arthritis. In addition to the clinical characteristics, genetic and biochemical differences suggest that JIA could be regarded as a general term covering various diseases. Complications described are uveitis, temporomandibular joint affection and growth disturbances. The therapeutic strategy should be planned individually according to age, subtype and disease activity and carried out as teamwork with several specialties. Drugs showing significant effectiveness in controlled studies are primarily methotrexate and sulphasalazine. An immunomodulating agent, etanercept, a soluble TNF alpha-receptor fusion protein, has shown a promising effect in severe polyarticular JIA refractory to methotrexate treatment.

    Full Text Available Juvenile hyaline fibromatosis is a rare, autosomal-recessive disease characterized by papular and nodular skin lesions, gingival hyperplasia, joint contractures and bone involvement in variable degrees. It is a connective tissue disorder with aberrant synthesis of glycosaminoglycans by fibroblasts. We report a 5-year-old female born of first-degree consanguineous marriage who presented with multiple, recurrent, painless, variable-sized nodules. Fine needle aspiration cytology smears and the subsequent histopathological examination from the nodules showed benign spindle cells in a Periodic acid Schiff-positive myxoid background. The disease has a relentlessly progressive course, with most patients surviving only up to the 4 th decade. As of now, there is no specific treatment for this disorder. Genetic counseling is essential to explain to parents about a 25% chance of having a diseased baby in any pregnancy. With the gene being mapped recently, techniques for antenatal diagnosis are likely to be established.

    Juvenile Dermatomiositis (JD) is autoimmune disease that progresses with time; JD's main differentiated syndromes are rash on the skin, poor function of muscles, and often developing invalidism. If the health practitioners manage to diagnose the JD on an early stage and prescribe the adequate treatment the disease will not progress aggressively. This approach is tangible for practical rheumatology and pediatric. The article aims to present the reasons of the development of the JD and calcinosis. The study based on the description of the patients with JD. There are distinguished the main symptoms of the disease in children: frequent and acute developments of muscles calcinosis, occasionally with diffuse character followed with hypotrophy of the muscles, contractures and invalidism. One of the patient cases that describe the article is the thirteen-year boy with JD indicating repeated sequence of the disease, with diffusive calcinosis, cellulitis followed with secondary infection and impaired vision.

    Full Text Available Juvenile Idiopathic Arthritis (JIA is the most chronic musculoskeletal disease of pediatric population. The chronic course of disease has a great impact on oral health. Temporomandibular joint is involved in JIA causing limited mouth opening with progressive open bite, retrognathia, microgenia and bird like appearance. Joints of upper and lower extremities are also involved. Effect on upper limb function leads to difficulty with fine motor movements required for brushing and flossing. This increases incidence of caries and periodontal disease in children. The cause of JIA is still poorly understood and none of the available drugs for JIA can cure the disease. However, prognosis has improved as a result of progress in disease classification and management. The dental practitioner should be familiar with the symptoms and oral manifestations of JIA to help manage as multidisciplinary management is essential.

    Limited information exists on juvenile homosexual homicide (JHH), that is, youths who perpetrate sexual homicides against same-sex victims. Only a handful of cases from the United States and internationally have been described in the literature. This study, the first of its kind, examines the epidemiology, victimology, victim-offender relationship, and weapon-use patterns in JHH offenders using a large U.S. database on homicide spanning three decades. The data for this study were derived from the Federal Bureau of Investigation's Supplementary Homicide Reports (SHRs) for the years 1976 through 2005. A total of 93 cases of JHH were identified. On average, three of these crimes occurred annually in the U.S., and there was a marked decline in its incidence over the study period. Ninety-five percent were male offender-male victim cases and 5% were female offender-female victim cases. JHH offenders were over-represented amongst all juvenile sexual murderers, similar to their adult counterparts. The majority of these boys were aged 16 or 17 and killed adult victims. They were significantly more likely to kill adult victims than other age groups, to be friends or acquaintances of the victims, and to use contact/edged weapons or firearms. Most offenders killed same-race victims, although Black offenders were significantly more likely than White offenders to kill interracially. A case report is provided to illustrate JHH. Further research is needed to promote our understanding of the pathogenesis, etiology, and associated risk factors for this aberrant form of murder by children.

    2016-01-01

    The study presented in this paper has shown that the generation of hard x rays and high-energy ions, which are detected in pinch implosion experiments, may be associated with the Coulomb explosion of the hot spot that is formed due to the outflow of the material from the pinch cross point. During the process of material outflow, the temperature of the hot spot plasma increases, and conditions arise for the plasma electrons to become continuously accelerated. The runaway of electrons from the hot spot region results in the buildup of positive space charge in this region followed by a Coulomb explosion. The conditions for the hot spot plasma electrons to become continuously accelerated have been revealed and estimates have been obtained for the kinetic energy of the ions generated by the Coulomb explosion.

    Full Text Available Juvenile rheumatoid arthritis (JRA is the most common rheumatic condition in children. JRA is defined as persistent arthritis in 1 or more joints for at least 6 weeks, with the onset before age 16 years. The etiology of JRA is unknown. Antigen activated CD4+ T cell stimulate monocytes, macrophages, and synovial fibroblasts to produce the cytokines Interleukin-1 (IL-1, IL-6, and tumor necrosis factor ? (TNF-? and to secrete matrix metalloproteinases, which lead to chronic inflammation due to infiltration of inflammatory cell, angiogenesis, destruction of cartilage and bone with pannus formation. The 3 major subtypes of JRA are based on the symptoms at disease onset and are designated systemic onset, pauciarticular onset, and polyarticular onset. For all patients, the goals of therapy are to decrease chronic joint pain and suppress the inflammatory process. Poor prognostic have been observed in patients with polyarticular onset, rheumatoid factor, persistent morning stiffness, tenosynovitis, involvement of the small joints, rapid appearance of erosions, active late onset childhood, subcutaneous nodules, or antinuclear antibody.

    Serious juvenile crimes require evaluation of a child as a criminal defendant in adult court. In such cases, it is crucial to understand jurors' attitudes, biases, and ability to follow legal instructions and maintain fairness. 308 undergraduate psychology students served as mock jurors, were randomly separated into four groups, and each group read the same realistic summary of a trial with the defendant's age presented as 13, 15, 17, or 21 years. Participants were asked to render guilty or not guilty verdicts and, if guilty, to suggest sentences. Chi-squared analysis indicated 13- and 15-year-old defendants were convicted less often than 17- and 21-year-old defendants, showing that jurors distinguished between juvenile defendants of different ages, but not minors and adults as defined by law. Additional analysis showed that age did not affect sentencing recommendations. Decision processes jurors use for juveniles tried as adults are discussed.

  11. Forensic aspects of juvenile violence.

    Science.gov (United States)

    Haller, L H

    2000-10-01

    The juvenile justice system was created because it was recognized that youthful offenders needed to be managed differently from adults. They were to receive habilitation services instead of punishment. It is now more than a century since the creation of the first juvenile court. After 67 years, the US Supreme Court, in Kent v United States stated that the model was not working because juveniles in the criminal justice system received no treatment and they had no rights. Because the issue that had been appealed was the lack of rights (not lack of treatment), the Court mandated that juveniles, like adults, be given certain rights. The following year, in In re Gault, the Court expanded these rights. Subsequent Supreme Court cases have dealt with these kinds of issues--that is, whether juvenile offenders are entitled to the same rights as adults and subject to the same penalties. The Supreme Court has never heard a "right to treatment" case, which is the other part of the juvenile court system. Cases have been brought in lower courts (e.g., Nelson v. Heyne, 1972) alleging inadequate treatment services, but no national impact has resulted. Thus, in general, children in the juvenile court system do not have an enforceable right to treatment and can obtain only what services are available in their jurisdictions. The services often are woefully inadequate. Sentencing a youth to probation, with the requirement that he or she participate in counseling or mental health treatment, is meaningless if services are not available. Community-based, model programs that provide effective treatment do exist. They are, as yet, the rare exception rather than the norm and, therefore, are not available to most youthful offenders. Incarcerated juveniles, obviously, cannot avail themselves of community programs. Litigation to give these youth the same rights as adults in penal institutions is not the answer because incarcerated adults don't have a right to treatment, only a right to be free

  12. The Heterogeneity of Juvenile Myositis

    2007-01-01

    Juvenile myositis is a heterogeneous group of systemic autoimmune diseases, in which clinical and serologic subgroups result in subsets of patients with distinct clinical manifestations, disease courses, immunogenetic associations, responses to therapy, and prognoses. A newly identified autoantibody of unknown specificity, anti-p155, is myositis-associated and seen in up to 20 – 30% of juvenile and adult DM patients. HLA DRB1*0301 and its linked allele DQA1*0501 have been identified as the major immunogenetic risk factor for juvenile and adult DM in both European- and African- American patients, and DQA1*0301 is an additional risk factor in European American patients. Several DQA1 alleles also are protective for juvenile DM. Environmental risk factors are poorly understood, but growing evidence suggests a role for infectious agents and ultraviolet radiation. The current therapy of juvenile DM consists of corticosteroids and other immunosuppressive agents, with the adjunctive treatment of cutaneous manifestations and rehabilitation. Therapeutic trials of biologic agents, including anti-TNFα and anti-CD20, may aid in developing promising new therapies for these disorders. PMID:17317616

    2016-02-01

    Spot welding is one of the most important joining technologies, especially in the automotive industry. Hitherto, the quality of spot welded joints is tested mainly by random destructive tests. A nondestructive testing technique offers the benefit of cost reduction of the testing procedure and optimization of the fabrication process, because every joint could be examined. This would lead to a reduced number of spot welded joints, as redundancies could be avoided. In the procedure described here, the spot welded joint between two zinc-coated steel sheets (HX340LAD+Z100MB or HC340LA+ZE 50/50) is heated optically on one side. Laser radiation and flash light are used as heat sources. The melted zone, the so called "weld nugget" provides the mechanical stability of the connection, but also constitutes a thermal bridge between the sheets. Due to the better thermal contact, the spot welded joint reveals a thermal behavior different from the surrounding material, where the heat transfer between the two sheets is much lower. The difference in the transient thermal behavior is measured with time resolved thermography. Hence, the size of the thermal contact between the two sheets is determined, which is directly correlated to the size of the weld nugget, indicating the quality of the spot weld. The method performs well in transmission with laser radiation and flash light. With laser radiation, it works even in reflection geometry, thus offering the possibility of testing with just one-sided accessibility. By using heating with collimated laser radiation, not only contact-free, but also remote testing is feasible. A further convenience compared to similar thermographic approaches is the applicability on bare steel sheets without any optical coating for emissivity correction. For this purpose, a proper way of emissivity correction was established.

  6. Surveys for presence of Oregon spotted frog (Rana pretiosa): background information and field methods

    Science.gov (United States)

    Pearl, Christopher A.; Clayton, David; Turner, Lauri

    2010-01-01

    The Oregon spotted frog (Rana pretiosa) is the most aquatic of the native frogs in the Pacific Northwest. The common name derives from the pattern of black, ragged-edged spots set against a brown or red ground color on the dorsum of adult frogs. Oregon spotted frogs are generally associated with wetland complexes that have several aquatic habitat types and sizeable coverage of emergent vegetation. Like other ranid frogs native to the Northwest, Oregon spotted frogs breed in spring, larvae transform in summer of their breeding year, and adults tend to be relatively short lived (3-5 yrs). Each life stage (egg, tadpole, juvenile and adult) has characteristics that present challenges for detection. Breeding can be explosive and completed within 1-2 weeks. Egg masses are laid in aggregations, often in a few locations in large areas of potential habitat. Egg masses can develop, hatch, and disintegrate in <2 weeks during warm weather. Tadpoles can be difficult to identify, have low survival, and spend most of their 3-4 months hidden in vegetation or flocculant substrates. Juveniles and adults are often difficult to capture and can spend summers away from breeding areas. Moreover, a substantial portion of extant populations are of limited size (<100 breeding adults), and field densities of all life stages are often low. An understanding of the biology of the species and use of multiple visits are thus important for assessing presence of Oregon spotted frogs. This report is meant to be a resource for USDA Region 6 Forest Service (FS) and OR/WA Bureau of Land Management (BLM) personnel tasked with surveying for the presence of Oregon spotted frogs. Our objective was to summarize information to improve the efficiency of field surveys and increase chances of detection if frogs are present. We include overviews of historical and extant ranges of Oregon spotted frog. We briefly summarize what is known of Oregon spotted frog habitat associations and review aspects of behavior and

    Adult Still's Disease was first described in 1971 by Bywaters in fourteen adult female patients who presented with symptoms indistinguishable from that of classic childhood Still's Disease (Bywaters, 1971). George Still in 1896 first recognized this triad of quotidian (daily) fevers, evanescent rash, and arthritis in children with what later became known as juvenile inflammatory arthritis (Still, 1990). Adult Onset Still's Disease (AOSD) is an inflammatory condition of unknown etiology characterized by an evanescent rash, quotidian fevers, and arthralgias. Numerous infectious agents have been associated with its presentation. This case is to our knowledge the first presentation of AOSD in the setting of Rocky Mountain Spotted Fever. Although numerous infectious agents have been suggested, the etiology of this disorder remains elusive. Nevertheless, infection may in fact play a role in triggering the onset of symptoms in those with this disorder. Our case presentation is, to our knowledge, the first case of Adult Onset Still's Disease associated with Rocky Mountain spotted fever (RMSF). PMID:20811570

    2016-02-01

    Juvenile dermatomyositis and juvenile scleroderma are rare multisystem autoimmune disorders. Although they share some pathognomonic hallmarks with adult onset myositis or scleroderma, there are significant differences in presentation, characteristics and associated features when the diseases present in childhood. In view of this, and the rarity of the conditions, it is important for care to be led by teams with expertise in pediatric rheumatology conditions. Prognosis has improved significantly in the West; likely due to early diagnosis and aggressive treatment with immunosuppressive medications. However, this trend is not replicated in the developing world. Early recognition of these diseases is crucial to achieve rapid and sustained remission and prevent disease or medication associated complications. This article aims to provide a practical overview for recognition, diagnosis and treatment of these conditions.

    About 20% of patients with juvenile chronic arthritis develop uveitis which is frequently bilateral. Risk factors for uveitis are: female gender, pauciarticular onset of arthritis, presence of circulating antinuclear antibodies, and the antigens HLA-DW5 and HLA-DPw2. The visual prognosis in patients with uveitis is good in 25% and fair in 50%. The remaining 25% develop cataract and/or glaucoma. The management of glaucoma is unsatisfactory, but the results of cataract surgery by lensectomy are good.

    2014-09-01

    Phylogenetic reconstructions are sensitive to the influence of ontogeny on morphology. Here, we use foetal/neonatal specimens of known species of living baleen whales (Cetacea: Mysticeti) to show how juvenile morphology of extant species affects phylogenetic placement of the species. In one clade (sei whale, Balaenopteridae), the juvenile is distant from the usual phylogenetic position of adults, but in the other clade (pygmy right whale, Cetotheriidae), the juvenile is close to the adult. Different heterochronic processes at work in the studied species have different influences on juvenile morphology and on phylogenetic placement. This study helps to understand the relationship between evolutionary processes and phylogenetic patterns in baleen whale evolution and, more in general, between phylogeny and ontogeny; likewise, this study provides a proxy how to interpret the phylogeny when fossils that are immature individuals are included. Juvenile individuals in the peramorphic acceleration clades would produce misleading phylogenies, whereas juvenile individuals in the paedomorphic neoteny clades should still provide reliable phylogenetic signals.

    16 July 2004 Astronomers using ESA’s X-ray observatory XMM-Newton have detected a small, bright ‘hot spot’ on the surface of the neutron star called Geminga, 500 light-years away. The hot spot is the size of a football field and is caused by the same mechanism producing Geminga’s X-ray tails. This discovery identifies the missing link between the X-ray and gamma-ray emission from Geminga. hi-res Size hi-res: 1284 kb Credits: ESA, P. Caraveo (IASF, Milan) Geminga's hot spot This figure shows the effects of charged particles accelerated in the magnetosphere of Geminga. Panel (a) shows an image taken with the EPIC instrument on board the XMM-Newton observatory. The bright tails, made of particles kicked out by Geminga’s strong magnetic field, trail the neutron star as it moves about in space. Panel (b) shows how electrically charged particles interact with Geminga’s magnetic field. For example, if electrons (blue) are kicked out by the star, positrons (in red) hit the star’s magnetic poles like in an ‘own goal’. Panel (c) illustrates the size of Geminga’s magnetic field (blue) compared to that of the star itself at the centre (purple). The magnetic field is tilted with respect to Geminga’s rotation axis (red). Panel (d) shows the magnetic poles of Geminga, where charged particles hit the surface of the star, creating a two-million degrees hot spot, a region much hotter than the surroundings. As the star spins on its rotation axis, the hot spot comes into view and then disappears, causing the periodic colour change seen by XMM-Newton.

  17. Watermarking spot colors in packaging

    Science.gov (United States)

    Reed, Alastair; Filler, TomáÅ.¡; Falkenstern, Kristyn; Bai, Yang

    2015-03-01

    In January 2014, Digimarc announced Digimarc® Barcode for the packaging industry to improve the check-out efficiency and customer experience for retailers. Digimarc Barcode is a machine readable code that carries the same information as a traditional Universal Product Code (UPC) and is introduced by adding a robust digital watermark to the package design. It is imperceptible to the human eye but can be read by a modern barcode scanner at the Point of Sale (POS) station. Compared to a traditional linear barcode, Digimarc Barcode covers the whole package with minimal impact on the graphic design. This significantly improves the Items per Minute (IPM) metric, which retailers use to track the checkout efficiency since it closely relates to their profitability. Increasing IPM by a few percent could lead to potential savings of millions of dollars for retailers, giving them a strong incentive to add the Digimarc Barcode to their packages. Testing performed by Digimarc showed increases in IPM of at least 33% using the Digimarc Barcode, compared to using a traditional barcode. A method of watermarking print ready image data used in the commercial packaging industry is described. A significant proportion of packages are printed using spot colors, therefore spot colors needs to be supported by an embedder for Digimarc Barcode. Digimarc Barcode supports the PANTONE spot color system, which is commonly used in the packaging industry. The Digimarc Barcode embedder allows a user to insert the UPC code in an image while minimizing perceptibility to the Human Visual System (HVS). The Digimarc Barcode is inserted in the printing ink domain, using an Adobe Photoshop plug-in as the last step before printing. Since Photoshop is an industry standard widely used by pre-press shops in the packaging industry, a Digimarc Barcode can be easily inserted and proofed.

    Juvenile hyaline fibromatosis (JHF) is a rare disorder of unknown etiology, very few cases of which have been reported in the literature. It presents similarities to other fibromatosys, but has its particular radiological features which differentiate it from them. The clinical findings consist of several, slow growing, subcutaneous nodules, flexion contractures of the joints which can lead to disability, gingival hypertrophy and muscular atrophy. The suspected radiological diagnosis is confirmed by electron microscopy study of the nodules, although light microscopy can also reveal suggestive images. Author (9 refs.)

    1999-01-01

    We study the temperature structure of the central part (r<18' ~0.7 h50**-1 Mpc) of the Coma cluster of galaxies using ASCA data. Two different analysis methods produce results in good agreement with each other and reveal the presence of interesting structures in the gas temperature distribution. Globally, the average temperature in the center of the cluster is 9.0 +/- 0.6 keV in good agreement with previous results. Superimposed on this, we find a cool area with temperatures of 4-6 keV associated with a filament of X-ray emission extending southeast from the cluster center detected by Vikhlinin and coworkers. We also find a hot spot with a temperature of around 13 keV displaced north from the central peak of emission. The distribution of the gas temperatures and relative specific entropies suggests that the cool features are most likely gas stripped from a galaxy group centered on NGC 4874 falling toward the core from outside, while the hot spot located ``ahead'' of this in-falling gas is due to shock heat...

    Full Text Available Wild animals are a primary source of protein (bushmeat for people living in or near tropical forests. Ideally, the effect of bushmeat harvests should be monitored closely by making regular estimates of offtake rate and size of stock available for exploitation. However, in practice, this is possible in very few situations because it requires both of these aspects to be readily measurable, and even in the best case, entails very considerable time and effort. As alternative, in this study, we use high-resolution, environmental favorability models for terrestrial mammals (N = 165 in Central Africa to map areas of high species richness (hot spots and hunting susceptibility. Favorability models distinguish localities with environmental conditions that favor the species' existence from those with detrimental characteristics for its presence. We develop an index for assessing Potential Hunting Sustainability (PHS of each species based on their ecological characteristics (population density, habitat breadth, rarity and vulnerability, weighted according to restrictive and permissive assumptions of how species' characteristics are combined. Species are classified into five main hunting sustainability classes using fuzzy logic. Using the accumulated favorability values of all species, and their PHS values, we finally identify weak spots, defined as high diversity regions of especial hunting vulnerability for wildlife, as well as strong spots, defined as high diversity areas of high hunting sustainability potential. Our study uses relatively simple models that employ easily obtainable data of a species' ecological characteristics to assess the impacts of hunting in tropical regions. It provides information for management by charting the geography of where species are more or less likely to be at risk of extinction from hunting.

However, in practice, this is possible in very few situations because it requires both of these aspects to be readily measurable, and even in the best case, entails very considerable time and effort. As alternative, in this study, we use high-resolution, environmental favorability models for terrestrial mammals (N = 165) in Central Africa to map areas of high species richness (hot spots) and hunting susceptibility. Favorability models distinguish localities with environmental conditions that favor the species' existence from those with detrimental characteristics for its presence. We develop an index for assessing Potential Hunting Sustainability (PHS) of each species based on their ecological characteristics (population density, habitat breadth, rarity and vulnerability), weighted according to restrictive and permissive assumptions of how species' characteristics are combined. Species are classified into five main hunting sustainability classes using fuzzy logic. Using the accumulated favorability values of all species, and their PHS values, we finally identify weak spots, defined as high diversity regions of especial hunting vulnerability for wildlife, as well as strong spots, defined as high diversity areas of high hunting sustainability potential. Our study uses relatively simple models that employ easily obtainable data of a species' ecological characteristics to assess the impacts of hunting in tropical regions. It provides information for management by charting the geography of where species are more or less likely to be at risk of extinction from hunting. PMID:25372705

    We describe digestive enzyme activity during the larval development of spotted rose snapper, Lutjanus guttatus. Trypsin, chymotrypsin, leucine aminopeptidase, pepsin, amylase, lipase, and acid and alkaline phosphatase activities were evaluated using spectrophotometric techniques from hatching through 30 days. The spotted rose snapper larvae present the same pattern of digestive enzyme activity previously reported for other species in which pancreatic (i.e., trypsin, chymotrypsin, amylase, and lipase) and intestinal (i.e., acid and alkaline phosphatases and leucine aminopeptidase) enzymatic activities are present from hatching allowing the larvae to digest and absorb nutrients in the yolk-sac and live prey by the time of first feeding. The digestive and absorption capacity of the spotted rose snapper increases during the larval development. A significant increase in individual activity of all enzymes occurs at 20 DAH, and around 25 DAH, the juvenile-type of digestion is observed with the appearance of pepsin secreted by the stomach, suggesting that maturation of the digestive function occurs around 20-25 DAH. Our results are in agreement with a previous suggestion that early weaning may be possible from 20 DAH. However, the patterns of enzymatic activities reported in our study should be considered during the formulation of an artificial diet for early weaning of the spotted rose snapper.

    Full Text Available Juvenile ossifying fibroma is a rare fibro-osseous lesion containing variable amount of calcified masses, which resembles bone or cementum within a fibrocellular connective tissue stroma. It has variable clinical behavior, highly aggressive in nature including invasion and destruction of adjacent anatomic structures with a strong tendency to recur. We reported a 28-year-old female patient with a growth in the upper left vestibule region extending from canine to molar region with clinical, histopathological, and radiological features are presented. Surgical management was done, and regular follow-up was advised.

    We present three patients with unilateral upper limb weakness (with muscular atrophy)-two of them with distal and one with proximal localization. The disease onset was between 18th end 35-th year of life; the disease course was biphasic (i.e. progressive within first 1 to 3 years, and stabilized during following 4-24 years). The laboratory investigations permitted to diagnose juvenile monomelic amyotrophy, an entity that is very rare outside Japan. Electromyography revealed neurogenic involvement with spinal features also in clinically unaffected muscles. We suggest that these results may support the hypothesis of this disease being a benign variant of spinal muscular atrophy.

    Competency to stand trial is interpreted as a protected due process right for all defendants and is defined as a defendant's fundamental knowledge and understanding of the criminal charges being filed, roles and procedures within the courtroom, and a general ability to work with the defense counsel. Questions of competency are most often raised by the judge, defense, or the prosecution, and competency evaluations are most often completed by psychiatrists or psychologists with forensic training or work experience. Mental illness, intellectual disability, developmental disorders, and developmental immaturity are the 4 main factors considered in most juvenile competency evaluations.

    2014-05-01

    Although the use of corticosteroids in juvenile idiopathic arthritis (JIA) is now much more limited owing to the availability of methotrexate and biological agents, there are clinical scenarios where it is still indicated. For example, corticosteroids may be indicated for intraarticular injections to prevent joint deformities, as a "bridge" drug to relieve symptoms in polyarticular disease while waiting for methotrexate and biologics to exert their full therapeutic effects, and in the treatment of chronic iridocyclitis, macrophage activation syndrome, and systemic JIA, although the advent of interleukin (IL)-1 and IL-6 blockers has greatly reduced the latter indication.

    Over the past decade there have been considerable changes in the classification and imaging of juvenile idiopathic arthritis (JIA). Radiology now has a considerable role in the management of JIA, the differential diagnosis, monitoring disease progression and detecting complications. The different imaging modalities available, their role and limitations are discussed in this article and the various disease features that the radiologist should be aware of are described. An approach to the imaging of the child with joint disease and in the monitoring of disease complications are also discussed. (orig.)

  9. THE STUDY OF FEATURES OF GUILT OF JUVENILE OFFENDERS IN THE CONTEXT OF JUVENILE JUSTICE

    Directory of Open Access Journals (Sweden)

    Natalija Vladimirovna Galkina

    2015-08-01

    Full Text Available The article is devoted to the results of empirical studies of the experiences of guilt of juvenile offenders in the context of juvenile justice where a minor appears as the subject of legal relations. Restorative approach of juvenile justice is based on an admission of guilt to the victim. In connection with it, the research of features of the guilt of minors who have committed an offence and the conditions for the development of the subjectivity will enhance understanding of the possibilities of restorative juvenile justice system in the prevention of juvenile delinquency.Thus, the results of empirical research presented in the article are important for determining of the psychological bases of realization of rehabilitation programs in the context of juvenile justice. In particular, the results are important for the organization and conduct of psychological work to overcome the psychological barriers in the behavior of juveniles having inherently maladaptive guilt and destructive psychological defense mechanisms.

    Full Text Available We present an empirical study to study the effects of different factors on juvenile delinquency. The investigation distributes 100 questionnaires among people who are involved with crime and analyzes their feedbacks. There are five hypotheses in our survey and we look to see whether family conditions, religion, economical conditions, media and physical and psychological characteristics play important role on juvenile delinquency in Iranian society. The results shows that while family conditions, physical and psychological characteristics play important role on juvenile delinquency, other factors do not statistically have any impact on juvenile delinquency. The study suggests that a better family condition could help reduce juvenile delinquency and people could guide their children through better consultations.

  1. Family transitions and juvenile delinquency.

    Science.gov (United States)

    Schroeder, Ryan D; Osgood, Aurea K; Oghia, Michael J

    2010-01-01

    There is a large body of research that shows children from non-intact homes show higher rates of juvenile delinquency than children from intact homes, partially due to weaker parental control and supervision in non-intact homes. What has not been adequately addressed in the research is the influence of changes in family structure among individual adolescents over time on delinquent offending. Using the first and third waves of the National Youth Study, we assess the effect of family structure changes on changes in delinquent offending between waves through the intermediate process of changes in family time and parental attachment. Although prior research has documented adolescents in broken homes are more delinquent than youth in intact homes, the process of family dissolution is not associated with concurrent increases in offending. In contrast, family formation through marriage or cohabitation is associated with simultaneous increases in offending. Changes in family time and parental attachment account for a portion of the family formation effect on delinquency, and prior parental attachment and juvenile offending significantly condition the effect of family formation on offending.

  2. Atherosclerosis in Juvenile Idiopathic Arthritis

    Full Text Available Atherosclerosis is a chronic inflammatory disease of the arteries. Clinical consequences of the atherosclerotic process occur in the adult population, however atherosclerotic process begins in childhood. The classic risk factors for atherosclerosis include obesity, dyslipidaemia, age, gender or family history. In recent years, attention has been drawn to the similarity between atherosclerotic inflammatory processes and inflammatory changes in the course of systemic connective tissue disease, in particular systemic lupus etythematosus (SLE or rheumatoid arthritis (RA. There is also observed the similarity of the pathogenetic background of development of atherosclerosis and juvenile idiopathic arthritis (JIA. Elevated levels of pro-inflammatory cytokines are observed in the course of juvenile idiopathic arthritis. Also homocysteine concentrations, which may play a significant role in the development of atherosclerotic lesions, are observed higher in patients with JIA. Some studies revealed higher carotid intima-media thickness (IMT index values in children with JIA. In view of the fact that atherosclerotic process begins as early as in childhood, the introduction of appropriate preventive measures in children is a matter of utmost importance.

Notice the difference in speed and direction of the various zones of the atmosphere. The interaction of the atmospheric clouds and storm shows how dynamic the Jovian atmosphere is.As Voyager 1 approached Jupiter in 1979, it took images of the planet at regular intervals. This sequence is made from 66 images taken once every Jupiter rotation period (about 10 hours). This time-lapse movie uses images taken every time Jupiter longitude 68W passed under the spacecraft. These images were acquired in the Blue filter from Jan. 6 to Feb. 3 1979. The spacecraft flew from 58 million kilometers to 31 million kilometers from Jupiter during that time.This time-lapse movie was produced at JPL by the Image Processing Laboratory in 1979.

    2012-01-01

    The Spotted Salamander is a wide-ranging salamander of the eastern United States that typically breeds in winter or early spring in ephemeral pools in lowland forests. Ambystoma maculatum is known to deposit 2-4 egg masses per year, each containing 1-250 eggs. As part of ongoing research into the ecology and reproductive biology of Spotted Salamanders in the Kisatchie District of Kisatchie National Forest in Natchitoches Parish, Louisiana, USA, we have been counting the number of embryos per egg mass. We captured seven female A. maculatum in a small pool, six of which were still gravid. We took standard measurements, including SVL, and then implanted a Passive Integrated Transponder (PIT tag) into each adult female as was the protocol. About an hour after processing these animals we marked new A. maculatum egg masses found in the same small pool using PVC pin flags pushed carefully through the outer jelly. We did not have enough time to process them that evening, and it was not until a few days later that we photographed those masses. We discovered that one of the masses contained a PIT tag in the outer jelly that corresponded to one of the six gravid females that were marked that same evening. To our knowledge, this is the first report of PIT tags being the means, albeit coincidentally, by which a particular egg mass of Ambystoma maculatum has been assigned to a particular female. For our purposes, losing the PIT tag from the adult female is counter to the goals of our study of this population, and we will no longer be implanting PIT tags into gravid females.

    The pathogen Batrachochytrium dendrobatidis (Bd) has been associated with amphibian declines in multiple continents, including western North America. We investigated Bd prevalence in Oregon spotted frog (Rana pretiosa), a species that has declined across its range in the Pacific Northwest. Polymerase chain reaction analysis of skin swabs indicated that Bd was prevalent within populations (420 of 617 juvenile and adults) and widespread among populations (36 of 36 sites) where we sampled R. pretiosa in Oregon and Washington. We rarely detected Bd in R. pretiosa larvae (2 of 72). Prevalence of Bd in postmetamorphic R. pretiosa was inversely related to frog size. We found support for an interactive effect of elevation and sampling date on Bd: prevalence of Bd generally increased with date, but this effect was more pronounced at lower elevations. We also found evidence that the body condition of juvenile R. pretiosa with Bd decreased after their first winter. Our data indicate that some Oregon spotted frog populations are currently persisting with relatively high Bd prevalence, but the risk posed by Bd is unknown. ?? 2010 International Association for Ecology and Health.

    White spot syndrome virus (WSSV) has caused significant losses in shrimp farms worldwide. Between 2004 and 2006, Pacific white shrimp Litopenaeus vannamei (Boone) were collected from 220 farms in Taiwan to determine the prevalence and impact of WSSV infection on the shrimp farm industry. Polymerase chain reaction (PCR) analysis detected WSSV in shrimp from 26% of farms. Juvenile shrimp farms had the highest infection levels (38%; 19/50 farms) and brooder shrimp farms had the lowest (5%; one of 20 farms). The average extent of infection at each farm was as follows for WSSV-positive farms: post-larvae farms, 71%; juvenile farms, 61%; subadult farms, 62%; adult farms, 49%; and brooder farms, 40%. Characteristic white spots, hypertrophied nuclei and basophilic viral inclusion bodies were found in the epithelia of gills and tail fans, appendages, cephalothorax and hepatopancreas, and virions of WSSV were observed. Of shrimp that had WSSV lesions, 100% had lesions on the cephalothorax, 96% in gills and tail fans, 91% on appendages and 17% in the hepatopancreas. WSSV was also detected in copepoda and crustaceans from the shrimp farms. Sequence comparison using the pms146 gene fragment of WSSV showed that isolates from the farms had 99.7-100% nucleotide sequence identity with four strains in the GenBank database--China (AF332093), Taiwan (AF440570 and U50923) and Thailand (AF369029). This is the first broad study of WSSV infection in L. vannamei in Taiwan.

    Hazardous wastes contaminated with radionuclides, chemicals, and explosives exist across the Department of Energy complex and need to be remediated due to environmental concerns. Currently, an opportunity is being developed to dramatically reduce remediation costs and to assist in the acceleration of schedules associated with these wastes by deploying a Hot Spot Removal System. Removing the hot spot from the waste site will remove risk driver(s) and enable another, more cost effective process/option/remedial alternative (i.e., capping) to be applied to the remainder of the site. The Hot Spot Removal System consists of a suite of technologies that will be utilized to locate and remove source terms. Components of the system can also be used in a variety of other cleanup activities. This Hot Spot Removal System Description document presents technologies that were considered for possible inclusion in the Hot Spot Removal System, technologies made available to the Hot Spot Removal System, industrial interest in the Hot Spot Removal System`s subsystems, the schedule required for the Hot Spot Removal System, the evaluation of the relevant technologies, and the recommendations for equipment and technologies as stated in the Plan section.

    In 2012-2014, our laboratory had investigated a total of 9 suspected front blind spot crashes, in which the medium and heavy goods vehicles pulled away from rest and rolled over the pedestrians, who were crossing immediately in front of the vehicles. The drivers alleged that they did not see any pedestrians through the windscreens or the front blind spot mirrors. Forensic assessment of the goods vehicles revealed the existence of front blind spot zones in 3 out of these 9 accident vehicles, which were attributed to the poor mirror adjustments or even the absence of a front blind spot mirror altogether. In view of this, a small survey was devised involving 20 randomly selected volunteers and their goods vehicles and 5 out of these vehicles had blind spots at the front. Additionally, a short questionnaire was conducted on these 20 professional lorry drivers and it was shown that most of them were not aware of the hazards of blind spots immediately in front of their vehicles, and many did not use the front blind spot mirrors properly. A simple procedure for quick measurements of the coverage of front blind spot mirrors using a coloured plastic mat with dimensional grids was also introduced and described in this paper.

    2012-10-15

    Black-spot poison ivy is an uncommon presentation of poison ivy (Toxicodendron) allergic contact dermatitis. A 78-year-old sought evaluation of a black spot present on her right hand amid pruritic vesicles. The presentation of a black spot on the skin in a clinical context suggesting poison ivy is indicative of black-spot poison ivy. Dermoscopy revealed a jagged, centrally homogeneous, dark brown lesion with a red rim. A skin sample was obtained and compared against a poison ivy standard using ultra-fast liquid chromatography-tandem mass spectrometry (UFLC-MS/MS). This finding confirmed the presence of multiple urushiol congeners in the skin sample. Black-spot poison ivy may be added to the list of diagnoses that show a specific dermoscopic pattern.

    2016-01-01

    Center-location of a laser spot is a problem of interest when the laser is used for processing and performing measurements. Measurement quality depends on correctly determining the location of the laser spot. Hence, improving and proposing algorithms for the correct location of the spots are fundamental issues in laser-based measurements. In this paper we introduce a Reaction Diffusion (RD) system as the main computational framework for robustly finding laser spot centers. The method presented is compared with a conventional approach for locating laser spots, and the experimental results indicate that RD-based computation generates reliable and precise solutions. These results confirm the flexibility of the new computational paradigm based on RD systems for addressing problems that can be reduced to a set of geometric operations. PMID:26938537

    Full Text Available Center-location of a laser spot is a problem of interest when the laser is used for processing and performing measurements. Measurement quality depends on correctly determining the location of the laser spot. Hence, improving and proposing algorithms for the correct location of the spots are fundamental issues in laser-based measurements. In this paper we introduce a Reaction Diffusion (RD system as the main computational framework for robustly finding laser spot centers. The method presented is compared with a conventional approach for locating laser spots, and the experimental results indicate that RD-based computation generates reliable and precise solutions.

    Many coral reef fishes exhibit distinct ontogenetic shifts in habitat use while some species settle directly in adult habitats, but there is not any general explanation to account for these differences in settlement strategies among coral reef fishes. This study compared distribution patterns and habitat associations of juvenile (young of the year) butterflyfishes to those of adult conspecifics. Three species, Chaetodon auriga, Chaetodon melannotus, and Chaetodon vagabundus, all of which have limited reliance on coral for food, exhibited marked differences in habitat association of juvenile versus adult individuals. Juveniles of these species were consistently found in shallow-water habitats, whereas adult conspecifics were widely distributed throughout a range of habitats. Juveniles of seven other species ( Chaetodon aureofasciatus, Chaetodon baronessa, Chaetodon citrinellus, Chaetodon lunulatus, Chaetodon plebeius, Chaetodon rainfordi, and Chaetodon trifascialis), all of which feed predominantly on live corals, settled directly into habitat occupied by adult conspecifics. Butterflyfishes with strong reliance on corals appear to be constrained to settle in habitats that provide access to essential prey resources, precluding their use of distinct juvenile habitats. More generalist butterflyfishes, however, appear to utilize distinct juvenile habitats and exhibit marked differences in the distribution of juveniles versus adults.

    PURPOSE: To test Sorsby's classical statement of axial eye growth as completed at the age of 13 years, with a view also to differentiating between basic eye growth and juvenile elongation associated with eventual refractive change towards myopia. METHODS: (i) A total of 160 healthy eyes close...... was preferred for conventional ultrasound oculometry due to its extreme repeatability of measuring values, thus making it well fitted for evaluating very small differences. In particular, this had bearing for the decelerating end phase of growth in the longitudinal investigation. RESULTS: Sorby's statement...... about age 13 as general limit found support from the cross-sectional data, which suggested stable emmetropic eye size from about 11-12 years, with an average apparently outgrown male emmetropic value of 23.5 mm versus females' 22.9 mm. The longitudinal data, however, showed emmetropic growth also beyond...

    2016-01-01

    We analyzed demographic, clinical and genetic characteristics of juvenile Huntington disease (JHD) and it frequency in an Argentinean cohort. Age at onset was defined as the age at which behavioral, cognitive, psychiatric or motor abnormalities suggestive of JHD were first reported. Clinical and genetic data were similar to other international series, however, in this context we identified the highest JHD frequency reported so far (19.72%; 14/71). Age at onset of JHD is challenging and still under discussion. Our findings reinforce the hypothesis that clinical manifestations, other than the typical movement disorder, may anticipate age at onset of even many years. Analyses of JHD cohorts are required to explore it frequency in populations with different backgrounds to avoid an underestimation of this rare phenotype. Moreover, data from selected populations may open new pathways in therapeutic approaches and may explain new potential correlations between HD presentations and environmental or biological factors.

    Control of disease activity and recovery of function are major issues in the treatment of children and adolescents suffering from juvenile idiopathic arthritis (JIA). Functional therapies including physiotherapy are important components in the multidisciplinary teamwork and each phase of the disease requires different strategies. While in the active phase of the disease pain alleviation is the main focus, the inactive phase requires strategies for improving motility and function. During remission the aim is to regain general fitness by sports activities. These phase adapted strategies must be individually designed and usually require a combination of different measures including physiotherapy, occupational therapy, massage as well as other physical procedures and sport therapy. There are only few controlled studies investigating the effectiveness of physical therapies in JIA and many strategies are derived from long-standing experience. New results from physiology and sport sciences have contributed to the development in recent years. This report summarizes the basics and main strategies of physical therapy in JIA.

  11. Superluminal Spot Pair Events in Astronomical Settings: Sweeping Beams

    CERN Document Server

    Nemiroff, Robert J

    2014-01-01

    Sweeping beams of light can cast spots moving with superluminal speeds across scattering surfaces. Such faster-than-light speeds are well-known phenomena that do not violate special relativity. It is shown here that under certain circumstances, superluminal spot pair creation and annihilation events can occur that provide unique information to observers. These spot pair events are {\\it not} particle pair events -- they are the sudden creation or annihilation of a pair of relatively illuminated spots on a scattering surface. Real spot pair illumination events occur unambiguously on the scattering surface when spot speeds diverge, while virtual spot pair events are observer dependent and perceived only when real spot radial speeds cross the speed of light. Specifically, a virtual spot pair creation event will be observed when a real spot's speed toward the observer drops below $c$, while a virtual spot pair annihilation event will be observed when a real spot's radial speed away from the observer rises above $c...

  12. Are antipredator behaviours of hatchery Salmo salar juveniles similar to wild juveniles?

    Science.gov (United States)

    Salvanes, A G V

    2017-01-27

    This study explores how antipredator behaviour of juvenile Atlantic salmon Salmo salar developed during conventional hatchery rearing of eggs from wild brood stock, compared with the behaviour of wild-caught juveniles from the same population. Juveniles aged 1+ years were tested in two unfamiliar environments; in one S. salar were presented with simulated predator attacks and in the other they were given the opportunity to explore an open-field arena. No difference was found in their spontaneous escape responses or ventilation rate (reflex responses) after simulated predator attacks. Hatchery-reared juveniles were more risk-prone in their behaviours than wild-caught individuals. Hatchery juveniles stayed less time in association with shelter. In the open-field arena, hatchery juveniles were more active than wild juveniles. Hatchery juveniles were also immobile for less time and spent a shorter amount of time than wild juveniles in the fringe of the open-field arena. Salmo salar size had no effect on the observed behaviour. Overall, this study provides empirical evidence that one generation of hatchery rearing does not change reflex responses associated with threats, whereas antipredator behaviour, typically associated with prior experience, was less developed in hatchery-reared than in wild individuals.

    Mitchell, Kimberly J; Finkelhor, David; Wolak, Janis

    2010-02-01

    Two studies were conducted to identify the incidence (Study 1) and characteristics (Study 2) of juvenile prostitution cases known to law enforcement agencies in the United States. Study 1 revealed a national estimate of 1,450 arrests or detentions (95% confidence interval [CI]: 1,287-1,614) in cases involving juvenile prostitution during a 1-year period. In Study 2, exploratory data were collected from a subsample of 138 cases from police records in 2005. The cases are broadly categorized into three main types: (a) third-party exploiters, (b) solo prostitution, and (c) conventional child sexual abuse (CSA) with payment. Cases were classified into three initial categories based on police orientation toward the juvenile: (a) juveniles as victims (53%), (b) juveniles as delinquents (31%), and (c) juvenile as both victims and delinquents (16%). When examining the status of the juveniles by case type, the authors found that all the juveniles in CSA with payment cases were treated as victims, 66% in third-party exploiters cases, and 11% in solo cases. Findings indicate law enforcement responses to juvenile prostitution are influential in determining whether such youth are viewed as victims of commercial sexual exploitation or as delinquents.

  14. Juvenile myoclonic epilepsy Epilepsia mioclônica juvenil

    2007-12-01

    Full Text Available Juvenile myoclonus epilepsy (JME is a common epileptic syndrome, the etiology of which is genetically determined. Its onset occurs from 6 through 22 years of age, and affected patients present with myoclonic jerks, often associated with generalized tonic-clonic seizures - the most common association - and absence seizures. JME is non-progressive, and there are no abnormalities on clinical examination or intellectual deficits. Psychiatric disorders may coexist. Generalized polyspike-and-waves are the most characteristic electroencephalographic pattern. Usual neuroimaging studies show no abnormalities. Atypical presentations should be entertained, as they are likely to induce misdiagnosis. Prevention of precipitating factors and therapy with valproic acid (VPA are able to control seizures in the great majority of patients. Whenever VPA is judged to be inappropriate, other antiepileptic drugs such as lamotrigine may be considered. Treatment should not be withdrawn, otherwise recurrences are frequent.A epilepsia mioclônica juvenil é uma síndrome epiléptica comum, cuja etiologia é fundamentada na genética. Inicia-se entre 6 e 22 anos e os indivíduos apresentam mioclonias, que podem ser acompanhadas por crises tônico-clônicas generalizadas - associação mais comum - e crises de ausência. A doença não é progressiva, e não há alterações detectáveis no exame físico ou déficits intelectuais. Distúrbios psiquiátricos podem coexistir. Polipontas-ondas lentas generalizadas constituem o padrão eletrencefalográfico ictal típico. Não há anormalidades em exames de imagem convencionais. Apresentações atípicas devem ser consideradas, pois predispõem a erros de diagnóstico. A prevenção de fatores desencadeantes e o uso de ácido valpróico (VPA controlam as crises epilépticas na grande maioria dos casos. Quando o VPA é inapropriado, outras drogas como a lamotrigina podem ser utilizadas. O tratamento não deve ser interrompido

    The high prevalence of mental health disorders among incarcerated juveniles is a matter of national and global concern. Juvenile justice personnel need accurate screening measures that identify youth requiring immediate mental health services. The purpose of this study was threefold: (a) to examine the utility of the Massachusetts Youth Screening Instrument, Version 2 (MAYSI-2) in identifying juveniles with mental health concerns in a large sample of juveniles (N = 4,009), (b) to provide data regarding rates of identified mental health needs in incarcerated youth, and (c) to provide descriptive comparisons to other studies using the MAYSI-2. Mean scores of subscales were compared with the MAYSI-2 normative samples and other recent studies. Results indicated that this population has a high occurrence of mental health symptoms and there is high variability in the severity of the symptoms. In addition, a multivariate analysis of variance test found significant differences in mental health problems across ethnic groups.

  3. CMB Cold Spot from Inflationary Feature Scattering

    CERN Document Server

    Wang, Yi

    2015-01-01

    We propose a "feature-scattering" mechanism to explain the cosmic microwave background cold spot seen from {\\it WMAP} and {\\it Planck} maps. If there are hidden features in the potential of multi-field inflation, the inflationary trajectory can be scattered by such features. The scattering is controlled by the amount of isocurvature fluctuations, and thus can be considered as a mechanism to convert isocurvature fluctuations into curvature fluctuations. This mechanism predicts localized cold spots (instead of hot ones) on the CMB. In addition, it may also bridge a connection between the cold spot and a dip on the CMB power spectrum at $\\ell \\sim 20$.

    2010-01-01

    The report of a significant deviation of the CMB temperature anisotropies distribution from Gaussianity (soon after the public release of the WMAP data in 2003) has become one of the most solid WMAP anomalies. This detection grounds on an excess of the kurtosis of the Spherical Mexican Hat Wavelet coefficients at scales of around 10 degrees. At these scales, a prominent feature --located in the southern Galactic hemisphere-- was highlighted from the rest of the SMHW coefficients: the Cold Spot. This article presents a comprehensive overview related to the study of the Cold Spot, paying attention to the non-Gaussianity detection methods, the morphological characteristics of the Cold Spot, and the possible sources studied in the literature to explain its nature. Special emphasis is made on the Cold Spot compatibility with a cosmic texture, commenting on future tests that would help to give support or discard this hypothesis.

  12. Measuring microfocus focal spots using digital radiography

    Energy Technology Data Exchange (ETDEWEB)

    Fry, David A [Los Alamos National Laboratory

    2009-01-01

    Measurement of microfocus spot size can be important for several reasons: (1) Quality assurance during manufacture of microfocus tubes; (2) Tracking performance and stability of microfocus tubes; (3) Determining magnification (especially important for digital radiography where the native spatial resolution of the digital system is not adequate for the application); (4) Knowledge of unsharpness from the focal spot alone. The European Standard EN 12543-5 is based on a simple geometrical method of calculating focal spot size from unsharpness of high magnification film radiographs. When determining microfocus focal spot dimensions using unsharpness measurements both signal-to-noise (SNR) and magnification can be important. There is a maximum accuracy that is a function of SNR and therefore an optimal magnification. Greater than optimal magnification can be used but it will not increase accuracy.

    ciega.INTRODUCTION. The glaucoma is infrequent in children but when it is present symptoms are not easily noticeable and produce severe consequences for visual health. The aim of present study was to characterize, from the clinical and epidemiologic point of view, the patients presenting with juvenile glaucoma seen in Ophthalmology services of the "Cerro" and "Pedro Borrás" Children Hospitals in Ciudad de La Habana from January, 2008 to December, 2009. METHODS. A prospective, longitudinal and epidemiologic study was conducted in 176 patients aged between 5 and 18 with a supposed glaucoma. Sample, after applied the inclusion and exclusion criteria, included 38 cases. Variables analyzed were: age at diagnosis, sex, skin color, family backgrounds according the relationship grade, corrected maximal visual acuity, type of refractive defect, characteristics of cell angle, central corneal thickness, the value of intraocular pressure, fundoscopy and campimetry alterations. RESULTS. In most of patients the diagnosis of juvenile glaucoma was a finding. The mean age at diagnosis was of 12,5 years, with slight predominance of males and of white skin color. The history of glaucoma in second grade blood relation relatives was more frequent. Most of cases had an optimal vision, some degree of myopia and open angle without obvious of cell angle where the more frequent was the presence of prominent iridic processes. CONCLUSIONS. There was predominance of a moderate decrease of corneal thickness and mean values of intraocular pressure of 26,91 mm Hg. The more frequent fundoscopy alteration found was the moderate papillary excavation (between 0,4 and 0,5 and as campimetry lesion, it was the increase in the black spot.

  16. Modeling deflagration waves out of hot spots

    Science.gov (United States)

    Partom, Yehuda

    2017-01-01

    It is widely accepted that shock initiation and detonation of heterogeneous explosives comes about by a two-step process known as ignition and growth. In the first step a shock sweeping through an explosive cell (control volume) creates hot spots that become ignition sites. In the second step, deflagration waves (or burn waves) propagate out of those hot spots and transform the reactant in the cell into reaction products. The macroscopic (or average) reaction rate of the reactant in the cell depends on the speed of those deflagration waves and on the average distance between neighboring hot spots. Here we simulate the propagation of deflagration waves out of hot spots on the mesoscale in axial symmetry using a 2D hydrocode, to which we add heat conduction and bulk reaction. The propagation speed of the deflagration waves may depend on both pressure and temperature. It depends on pressure for quasistatic loading near ambient temperature, and on temperature at high temperatures resulting from shock loading. From the simulation we obtain deflagration fronts emanating out of the hot spots. For 8 to 13 GPa shocks, the emanating fronts propagate as deflagration waves to consume the explosive between hot spots. For higher shock levels deflagration waves may interact with the sweeping shock to become detonation waves on the mesoscale. From the simulation results we extract average deflagration wave speeds.

  17. Unblinding the dark matter blind spots

    Han, Tao; Kling, Felix; Su, Shufang; Wu, Yongcheng

    2017-02-01

    The dark matter (DM) blind spots in the Minimal Supersymmetric Standard Model (MSSM) refer to the parameter regions where the couplings of the DM particles to the Z-boson or the Higgs boson are almost zero, leading to vanishingly small signals for the DM direct detections. In this paper, we carry out comprehensive analyses for the DM searches under the blind-spot scenarios in MSSM. Guided by the requirement of acceptable DM relic abundance, we explore the complementary coverage for the theory parameters at the LHC, the projection for the future underground DM direct searches, and the indirect searches from the relic DM annihilation into photons and neutrinos. We find that (i) the spin-independent (SI) blind spots may be rescued by the spin-dependent (SD) direct detection in the future underground experiments, and possibly by the indirect DM detections from IceCube and SuperK neutrino experiments; (ii) the detection of gamma rays from Fermi-LAT may not reach the desirable sensitivity for searching for the DM blind-spot regions; (iii) the SUSY searches at the LHC will substantially extend the discovery region for the blind-spot parameters. The dark matter blind spots thus may be unblinded with the collective efforts in future DM searches.

    2013-08-01

    Juvenile fibromyalgia (JFM) is a disease in which patients complain of acute and chronic severe pain, an overt primary cause for which cannot be found or surmised. Although patients with JFM mainly complain of systemic pain or allodynia in the medical interview and physical examination, the concept of the disease is the total sum of painful illness, chronic fatigue, hypothermia and many other autonomic symptoms and signs. Many issues are interacting including individual traits (personality, temperament, sensitivity, memory of pain; age: early adolescence), individual states (self-esteem, anxiety, developmental level), and external stressors (parent especially mother, school environment). JFM is diagnosed on the combination of disease history, physical examination to determine the 18 tender points and allodynia, pain from gently touching their hair, and negative results of blood tests (inflammatory markers, thyroid function, myogenic enzymes). The goals of treatment are the following: restoration of function and relief of pain. Psychological support is advocated. Although the exact number of patients with JFM is still to be elucidated, it seems to be growing because pediatric rheumatologists in Japan encounter children with a wide variety of musculoskeletal pains. This guideline describes how to diagnose JFM in children and how to treat them appropriately.

    The literature has long pointed to heightened frequencies of learning disabilities (LD) within the population of law offenders; however, a systematic appraisal of these observations, careful estimation of these frequencies, and investigation of their correlates and causes have been lacking. Here we present data collected from all youth (1,337 unique admissions, mean age 14.81, 20.3% females) placed in detention in Connecticut (January 1, 2010-July 1, 2011). All youth completed a computerized educational screener designed to test a range of performance in reading (word and text levels) and mathematics. A subsample (n = 410) received the Wide Range Achievement Test, in addition to the educational screener. Quantitative (scale-based) and qualitative (grade-equivalence-based) indicators were then analyzed for both assessments. Results established the range of LD in this sample from 13% to 40%, averaging 24.9%. This work provides a systematic exploration of the type and severity of word and text reading and mathematics skill deficiencies among juvenile detainees and builds the foundation for subsequent efforts that may link these deficiencies to both more formal, structured, and variable definitions and classifications of LD, and to other types of disabilities (e.g., intellectual disability) and developmental disorders (e.g., ADHD) that need to be conducted in future research.

    The striatum of the primate brain can be subdivided into three distinct anatomical subregions: caudate (CAU), putamen (PUT), and ventral striatum (VS). Although these subregions share several anatomical connections, cell morphological, and histochemical features, they differ considerably in their vulnerability to different neurological and psychiatric diseases, and these brain regions have significantly different functions in health and disease. In order to better understand the molecular underpinnings of the different disease and functional vulnerabilities, transcriptional profiles were generated from the CAU, PUT, and VS of five juvenile rhesus macaques (Macaca mulatta) using human cDNA neuromicroarrays containing triplicate spots of 1227 cDNAs. Differences in microarray gene expression were assessed using z score analysis and 1.5-fold change between paired subregions. Clustering of genes based on dissimilarity of expression patterns between regions revealed subregion specific expression profiles encoding G-protein-coupled receptor signaling transcripts, transcription factors, kinases and phosphatases, and cell signaling and signal transduction transcripts. Twelve transcripts were examined using quantitative real-time PCR (qPCR), and 81% demonstrated alterations similar to those seen with microarray analysis, some of which were statistically significant. Subregion specific transcription profiles support the anatomical differentiation and potential disease vulnerabilities of the respective subregions. PMID:16455077

    Full Text Available Enzyme immunoassays (EIA that measure faecal testosterone metabolites (fTM are useful tools to monitor gonadal activity. The aim of this study was to validate an "in-house" epiandrosterone EIA to monitor fTM in spotted hyenas. FTM were characterised in a male and a female hyena that each received an injection of 3H-testosterone. High-performance liquid chromatography (HPLC analyses revealed a cluster of highly polar enzyme-hydrolysable hormone metabolite conjugates. We performed hydrolysis using β-glucuronidase to deconjugate metabolites and improve sensitivity of the assay. Because β-glucuronidase from Helix pomatia has been reported to bias testosterone measurements in some species, we compared the enzymatic activity of the commonly used β-glucuronidase extracted from H. pomatia with the same enzyme from Escherichia coli. Our results showed that β-glucuronidases from both sources produced similar results from spotted hyena faeces. We therefore hydrolysed samples with H. pomatia enzymes. HPLC analyses also demonstrated that following hydrolysis the epiandrosterone EIA measured significant amounts of immunoreactive metabolites corresponding to radiolabelled metabolites in both sexes. Additionally, HPLC and GC-MS analyses confirmed the presence of epiandrosterone in faeces of spotted hyenas. The biological relevance of the epiandrosterone EIA was validated by demonstrating (1 a significant increase in fTM levels in response to a testosterone injection within 16 h, (2 no biological responsiveness to an adrenocorticotropic hormone (ACTH injection and (3 significant differences in fTM levels between juvenile males and adult immigrant males in a free-ranging wild population. Our results clearly demonstrate that the epiandrosterone EIA is a reliable non-invasive method to monitor gonadal activity in spotted hyenas.

    Almost one and a half centuries ago, Abbe [Arch. Mikrosk. Anat. 9, 413 (1873), 10.1007/BF02956173] and shortly after Lord Rayleigh [Philos. Mag. Ser. 5 8, 261 (1879), 10.1080/14786447908639684] showed that, when an optical lens is illuminated by a plane wave, a diffraction-limited spot with radius 0.61 λ /sinα is obtained, where λ is the wavelength and α is the semiangle of the beam's convergence cone. However, spots with much smaller features can be obtained at the focal plane when the lens is illuminated by an appropriately structured beam. Whereas this concept is known for light beams, here, we show how to realize it for a massive-particle wave function, namely, a free electron. We experimentally demonstrate an electron central spot of radius 106 pm, which is more than two times smaller than the diffraction limit of the experimental setup used. In addition, we demonstrate that this central spot can be structured by adding orbital angular momentum to it. The resulting superoscillating vortex beam has a smaller dark core with respect to a regular vortex beam. This family of electron beams having hot spots with arbitrarily small features and tailored structures could be useful for studying electron-matter interactions with subatomic resolution.

    Full Text Available Huntington disease (HD is a progressive neurodegenerative disorder, characterized by autosomal dominant inheritance, movement disorder, dementia, and behavioural disturbances. It is caused by a mutation in IT15 gene on chromosome 4p16.3, which leads to unstable CAG trinucleotide repeat expansion. The onset of juvenile HD occurs before the 2nd decade of life and comprises approximately 10% of total HD patients. Juvenile HD differs in symptomatology and is usually transmitted from paternal side with genetic anticipation phenomenon. Magnetic resonance imaging (MRI of the brain shows specific changes of early affection of caudate nucleus and putamen. Multidisciplinary approach with symptomatic treatment of specific symptoms is the current available management. Gene editing and gene silencing treatment are under trial. Hereby, we introduce a case of an 8-year-old boy, who presented with typical symptoms of juvenile HD, positive family history with genetic anticipation phenomenon and characteristic MRI findings.

  10. Corporal and capital punishment of juveniles.

    Frazier, H C

    1990-01-01

    There is a previously unobserved connection between corporal punishment of public school children and capital punishment of juveniles. Both are barometers of acceptable levels of violent punishment and their elimination is a hallmark of a maturing and decent society. Within a majority of the eighteen states where school authorities most frequently strike children are housed 25 of the nation's 28 juvenile death row inmates. On average, the homicide rates of these jurisdictions are two and a half times greater than those that have abolished both state-sanctioned corporal and capital punishment or limit death sentences to those age eighteen and older at the time of their crime(s). Most of the eighteen state abolitions of corporal punishment occurred in the 1980's. The US Supreme Court has ruled both corporal and capital punishment of juveniles constitutional. Additional state legislative abolition of both is anticipated in the 1990s.

    Full Text Available ResumenEl término «delincuencia juvenil» fue acuñado en Inglaterra en el año 1815, “Se entiende por delincuencia juvenil el conjunto de delitos, contravenciones o comportamientos socialmente reprochables, que cometen las personas consideradas como jóvenes por la ley”1 . Cada Estado está sujeto a su propio sistema jurídico, para algunos es delincuente juvenil el adolescente que comete acciones sancionadas por la ley sin importar su gravedad, otros Estados sólo consideran como delincuente juvenil al joven que comete un acto delictivo grave.El fenómeno de la delincuencia juvenil es algo que se inscribe en los espacios de una sociedad en la cual su estructura material, y su formación social consecuente, se halla en una profunda crisis. Que jóvenes conformen bandas de delincuencia organizada nos está indicando que son el resultado de la misma criminalidad general que se ha apoderado de la sociedad en la perspectiva de lograr sobrevivir materialmente. El capitalismo no es sólo acumulación de riqueza sino concentración de la misma en muy pocas manos; y todo el sistema institucional y legal tiende a favorecer ese fenómeno porque éste constituye la supra estructura del modo de producción capitalista. Así como los adultos se organizan para delinquir, lo hacen los niños y los jóvenes a partir de una edad en la cual pueden percibir que la sociedad no es sana y no tienen porvenir humano en ella. Abandonados y sujetos a la violencia que engendra el sistema, ellos simplemente responden en una manifestación de reflejos condicionados que sostienen la sobrevivencia en forma instintiva; “los niños no saben de normas legales sino de formas de sobrevivir a semejante situación; el instinto de sobrevivencia no tiene edades ni la normatividad puede incidir en él”.Palabras ClavesDelincuencia juvenil, Jóvenes, Criminalidad, Familia, Factores, Acto delictivo, Responsabilidad Penal.AbstractThe term “juvenile delinquency” was coined in

    This study sought to (1) quantify the baseline immunization coverage of adolescents entering the juvenile justice system and (2) assess the effect of detention-based care on immunization coverage in youth. A cross-sectional retrospective chart review was performed of 279 adolescents detained at a large juvenile detention facility. Only 3% of adolescents had received all study immunizations prior to detention. Before detention, immunization coverage was significantly lower than that for the general adolescent population for all vaccines except the first doses of hepatitis A and varicella-zoster virus vaccines. Subsequent to detention, most individual immunization coverage levels increased and were significantly higher than in the general adolescent population. The routine administration of immunizations in the juvenile justice setting can help detained youth achieve levels of immunization coverage similar to their nondetained peers.

    The effects of sublethal concentrations of tributyltin (TBT) on growth of juvenile clams Ruditapes decussatus were determined during exposure to TBT concentrations of 50, 100 and 250 ng l(-1) (as Sn) for a period up to two years. Length and weight of clams increased continuously in all treatments throughout the experimental period, and, overall, rates were not significantly influenced by TBT exposure, although final length and weight were inversely related to increasing TBT concentration. Juvenile R. decussatus therefore appear to be less sensitive to TBT than larval stages. Some juveniles exposed to TBT developed abnormal shell growth, laterally, changing the typical flattened shape of clams into a more "rounded" form. This characteristic was more visible in the anterior margins of valves than posteriorly, and mainly observed in clams exposed to TBT at 50 ng l(-1) (as Sn).

    A 14-year-old boy presented with months of severe widespread musculoskeletal pain. He was profoundly fatigued and unable to attend school. Laboratory evaluation, including complete blood count, comprehensive metabolic panel, inflammatory markers, and thyroid function, was unrevealing. Physical examination was also normal except for multiple tender points. The patient was diagnosed with juvenile primary fibromyalgia syndrome and referred for multidisciplinary treatment including physical therapy, exercise, and counseling, and his daily functioning gradually improves. Juvenile fibromyalgia is a complex syndrome that often severely limits patients' activities and can impede normal adolescent development. Effective treatment requires an understanding of the biologic, psychologic, and social factors contributing to the perpetuation of chronic pain. The author reviews the diagnostic criteria, pathophysiology, and treatment of juvenile fibromyalgia. Medications, particularly antidepressants and anticonvulsants, can be useful adjuncts to therapy. However, multimodal pain management including intensive physical therapy, exercise, counseling, and sleep hygiene is most effective in treating fibromyalgia.

    Age determination from images can be of vital importance, particularly in cases involving suspected child sexual abuse (CSA). It is imperative to determine if an individual depicted in such an image is indeed a child, with a more concise age often sought, as this may affect the severity of offender sentencing. The aims of this study were to establish the accuracy of visual age estimation of the juvenile face in children aged between 0 and 16years and to determine if varying levels of exposure to children affected an individual's ability to assess age from the face. An online questionnaire consisting of 30 juvenile face images was created using SurveyMonkey®. The overall results suggested poor accuracy for visual age estimation of juvenile faces. The age, sex, occupation and number of children of the participants did not affect the ability to estimate age from facial images. Similarly, the sex and age of the juvenile faces did not appear to affect the accuracy of age estimation. When specific age groups are considered, sex may have an influence on age estimation, with female faces being aged more accurately in the younger age groups and male faces more accurate after the age of 11years, however this is based on a small sample. This study suggests that the accuracy of juvenile age estimation from the face alone is poor using simple visual assessment of images. Further research is required to determine exactly how age is assessed from a facial image, if there are indicators, or features in particular that lead to over- or under-estimation of juvenile age.

    2015-01-01

    Acoustic modes of oscillation are affected by stellar activity, however it is unclear how starspots contribute to these changes. Here we investigate the non-magnetic effects of starspots on global modes with angular degree $\\ell \\leq 2$ in highly active stars, and characterize the spot seismic signature on synthetic light curves. We perform 3D time-domain simulations of linear acoustic waves to study their interaction with a model starspot. We model the spot as a 3D change in the sound speed stratification with respect to a convectively stable stellar background, built from solar Model S. We perform a parametric study by considering different depths and perturbation amplitudes. Exact numerical simulations allow investigation of the wavefield-spot interaction beyond first order perturbation theory. The interaction of the axisymmetric modes with the starspot is strongly nonlinear. As mode frequency increases, the frequency shifts for radial modes exceed the value predicted by linear theory, while the shifts for...

    Interest in thin-film nanostructures as building blocks for nanoelectronics and nanoelectromechanical systems (NEMS) is increasing. Resistance spot welding (RSW) on a nano or micro scale can play a significant role; similar to that of its macro counterpart for forming connections in device assembly processes. This Note presents a novel micron scale RSW technique using a microgripper as mobile spot welding electrodes to assemble ultra-thin film nanostructures. As an example, assembly of three-dimensional helical nanobelt (HNB) based device was successfully demonstrated using the proposed system. The spot-welding process was fully monitored by the built-in capacitive micro force sensor of the microgripper. Experiments show that RSW, using the microgripper, provides a stable electrical contact with sufficient mechanical strength for the construction of devices such as HNB based devices demonstrated here.

    An empty spot refers to an empty hard-to-fill space which can be found in the records of the social interaction, and is the clue to the persons in the underlying social network who do not appear in the records. This contribution addresses a problem to predict relevant empty spots in social interaction. Homogeneous and inhomogeneous networks are studied as a model underlying the social interaction. A heuristic predictor function method is presented as a new method to address the problem. Simulation experiment is demonstrated over a homogeneous network. A test data set in the form of market baskets is generated from the simulated communication. Precision to predict the empty spots is calculated to demonstrate the performance of the presented method.

    Juvenile dermatomyositis is an autoimmune connective tissue disease occurring in children less than 16 years old. It is part of a heterogeneous group of muscle diseases called idiopathic Iiflammatory myopathies. It had previously been reported in black Africans resident in UK. However, there is no documented case reported from Africa. The index sign of heliotrope rashes is often difficult to visualise in the black skin. An 11-year-old Nigerian girl presenting with clinical, laboratory and histopathological features of juvenile dermatomyositis is presented here. It is hoped that this case will heighten the index of suspicion of this condition among medical practitioners in Africa. PMID:24706700

    An estimated 1.8 million juveniles were arrested in the United States for delinquency in 2009. Previous studies indicate high rates of exposure to traumatic events and posttraumatic stress (PTS) symptoms for these youths. This study examined PTS in a sample of 170 youths in juvenile detention. The results of this study reveal higher rates of PTS symptoms (21%) compared to national rates (6%). The data also suggest youths suffering from more PTS symptoms also report higher depression, anxiety, anger, family relationship worries, thought problems, and attention problems. These factors provide a direction for continued practice targeting these youths.

  9. Juvenile rheumatoid arthritis: therapeutic perspectives.

    Science.gov (United States)

    Chikanza, Ian C

    2002-01-01

    Juvenile rheumatoid arthritis (JRA) is the most common childhood chronic systemic autoimmune inflammatory disease. The therapeutic approach to JRA has, to date, been casual and based on extensions of clinical experiences gained in the management of adult rheumatoid arthritis (RA). The physiology of inflammation has been systemically studied and this has led to the identification of specific therapeutic targets and the development of novel approaches to the management of JRA. The classical treatments of the disease such as methotrexate, sodium aurothiomalate and sulfasalazine, are not always effective in controlling RA and JRA. This has necessitated the development of novel agents for treating RA, most of which are biological in nature and are targeted at specific sites of the inflammatory cascades. These biological therapeutic strategies in RA have proved successful and are being applied in the management of JRA. These developments have been facilitated by the advances in molecular biology which have heralded the advent of biodrugs (recombinant proteins) and gene therapy, in which specific genes can be introduced locally to enhance in vivo gene expression or suppress gene(s) of interest with a view to down-regulating inflammation. Some of these biodrugs, such as anti-tumor necrosis factor alpha (anti-TNFalpha), monoclonal antibodies (infliximab, adalimumab), TNF soluble receptor constructs (etanercept) and interleukin-1 receptor antagonist (IL-1Ra) have been tested and shown to be effective in RA. Etanercept has now been licensed for JRA. Clinical trials of infliximab in JRA are planned. Studies show that the clinical effects are transient, necessitating repeated treatments and the risk of vaccination effects. Anti-inflammatory cytokines such as IL-4, IL-10, transforming growth factor-beta and interferon-beta (IFN-beta) are undergoing clinical trials. Many of these agents have to be administered parenterally and production costs are very high; thus, there is a need

  11. Whole Genome Amplification from Blood Spot Samples.

    Science.gov (United States)

    Sørensen, Karina Meden

    2015-01-01

    Whole genome amplification is an invaluable technique when working with DNA extracted from blood spots, as the DNA obtained from this source often is too limited for extensive genetic analysis. Two techniques that amplify the entire genome are common. Here, both are described with focus on the benefits and drawbacks of each system. However, in order to obtain the best possible WGA result the quality of input DNA extracted from the blood spot is essential, but also time consumption, flexibility in format and elution volume and price of the technology are factors influencing system choice. Here, three DNA extraction techniques are described and the above aspects are compared between the systems.

    Migration conveys an immense challenge, especially for juvenile birds coping with enduring and risky journeys shortly after fledging. Accordingly, juveniles exhibit considerably lower survival rates compared to adults, particularly during migration. Juvenile white storks (Ciconia ciconia), which are known to rely on adults during their first fall migration presumably for navigational purposes, also display much lower annual survival than adults. Using detailed GPS and body acceleration data, we examined the patterns and potential causes of age-related differences in fall migration properties of white storks by comparing first-year juveniles and adults. We compared juvenile and adult parameters of movement, behaviour and energy expenditure (estimated from overall dynamic body acceleration) and placed this in the context of the juveniles' lower survival rate. Juveniles used flapping flight vs. soaring flight 23% more than adults and were estimated to expend 14% more energy during flight. Juveniles did not compensate for their higher flight costs by increased refuelling or resting during migration. When juveniles and adults migrated together in the same flock, the juvenile flew mostly behind the adult and was left behind when they separated. Juveniles showed greater improvement in flight efficiency throughout migration compared to adults which appears crucial because juveniles exhibiting higher flight costs suffered increased mortality. Our findings demonstrate the conflict between the juveniles' inferior flight skills and their urge to keep up with mixed adult-juvenile flocks. We suggest that increased flight costs are an important proximate cause of juvenile mortality in white storks and likely in other soaring migrants and that natural selection is operating on juvenile variation in flight efficiency.

  13. Variation in T-SPOT.TB spot interpretation between independent observers from different laboratories.

    T-SPOT.TB is a specific assay for the diagnosis of tuberculosis. The assay needs to be performed with freshly isolated cells, and interpretation requires training. T-SPOT.TB has been used in various clinical-epidemiological settings, but so far no studies have evaluated the effect of interobserver variation in test reading. Our aim was to evaluate variation between different observers in reading T-SPOT.TB results. The study was nested within an ongoing cohort study, in which part of the T-SPOT.TB had been performed with frozen material. Culture plates were read visually by four different observers from two laboratories and by two automated readers. Of 313 T-SPOT.TB assays, 235 were performed with fresh cells and 78 were performed with frozen cells. No significant difference was found between results obtained with fresh cells and those obtained with frozen cells. The percentage of positive results varied between readers by maximally 15%; five/six raters were within a 6% difference in positive results. Analysis of the observed interrater differences showed that some individuals systematically counted more spots than others did. Because test interpretation includes subtraction of background values, this systematic variance had little influence on interindividual differences. The test result as positive or negative varied between independent raters, mainly due to samples with values around the cutoff. This warrants further study regarding determinants affecting the reading of T-SPOT.TB.

    2016-08-01

    The purpose of this study is to examine the impact of being juvenile on sentencing in the criminal justice system. More specifically, youth transferred to criminal court are compared to adults in terms of likelihood of incarceration, jail length, and prison length. In this study, 2 national data sets are merged. The juvenile sample includes 3,381 convicted offenders, and the adult sample is comprised of 6,529 convicted offenders. The final sample is 9,910 offenders across 36 U.S. counties. The key independent variable is juvenile status, and the dependent variables are incarceration, jail length, and prison length. Because of the multilevel nature of the data, hierarchical linear modeling is used across all models. Juveniles are punished less severely in the jail incarceration decision. However, when youth are actually sentenced to incarceration (either jail or prison), they are given longer confinement time than adults. (PsycINFO Database Record

    The occurrence and distribution of white spot syndrome virus (WSSV) among cultured and captured penaeid shrimps and crustaceans in the east coast of India was determined from November 1999 to April 2002 using PCR as a diagnostic tool. A total of 630 cultured samples consisting of 280 postlarvae collected from nine different hatcheries and 350 juvenile shrimps (40-60-day-old) collected from 18 different culture ponds were screened for WSSV. Of these cultured samples tested 53% were found to be single-step PCR positive. A total of 419 samples of captured crustaceans viz., Penaeus monodon brooders, P. indicus juveniles, Metapenaeus spp., crab Scylla serrata and Squilla mantis were also screened for WSSV by PCR, 23% of them were infected with WSSV. This study concluded that WSSV could be widespread in cultured and captured shrimps and other crustaceans in India. The results indicate that PCR screening of WSSV infection and rejection of infected stocks greatly assists shrimp aquaculture farmers for successful production and harvest.

  18. Spot Weight Adaptation for Moving Target in Spot Scanning Proton Therapy

    Directory of Open Access Journals (Sweden)

    2015-05-01

    Full Text Available Purpose: This study describes a real-time spot weight adaptation method in spot-scanning proton therapy for moving target or moving patient, so that the resultant dose distribution closely matches the planned dose distribution. Materials and Methods: The method proposed in this study adapts the weight (MU of the delivering pencil beam to that of the target spot it will actually hit during patient/target motion. The target spot a certain delivering pencil beam may hit relies on patient monitoring and/or motion modeling using four-dimensional (4D CT. After the adapted delivery, the required total weight (MU for this target spot is then subtracted from the planned value. With continuous patient motion and continuous spot scanning, the planned doses to all target spots will eventually be all fulfilled. In a proof-of-principle test, a lung case was presented with realistic temporal and motion parameters; the resultant dose distribution using spot weight adaptation was compared to that without using this method. The impact of the real-time patient/target position tracking or prediction was also investigated.Results: For moderate motion (i.e., mean amplitude 0.5 cm, D95% to the planning target volume (PTV was only 81.5% of the prescription (RX dose; with spot weight adaptation PTV D95% achieves 97.7%RX. For large motion amplitude (i.e., 1.5 cm, without spot weight adaptation PTV D95% is only 42.9% of RX; with spot weight adaptation, PTV D95% achieves 97.7%RX. Larger errors in patient/target position tracking or prediction led to worse final target coverage; an error of 3mm or smaller in patient/target position tracking is preferred. Conclusion: The proposed spot weight adaptation method was able to deliver the planned dose distribution and maintain target coverage when patient motion was involved. The successful implementation of this method would rely on accurate monitoring or prediction of patient/target motion.

    2014-12-01

    Probation is the most common disposition for adjudicated youth, but little is known about which specific requirements are commonly imposed on juveniles, the requirements with which juveniles most often fail to comply, and how certain youth characteristics and/or imposed requirements might relate to probation noncompliance. An investigation of 120 archived files of youth represented by an urban public defender's office identified 29 probation requirements imposed on youth and 18 requirements with which youth commonly failed to comply. Results revealed that 52% of youth failed to comply with at least one probation requirement; prior probation noncompliance and race were both significantly associated with noncompliance in the examined probation disposition. In addition, the probability of probation noncompliance was significantly higher when youth received either of two substance-related probation requirements: drug tests or drug and alcohol counseling. Such results may prompt further investigation of juvenile probation-related predictors, identify areas of need for clinical service provision to foster successful completion of probation requirements, and help identify areas of potential biases among juvenile court personnel.

    2011-07-01

    In baseball, the sweet spot is a special place on a bat where the batter can hit the ball with the most power. It is the place where the performances of the batter and pitcher collide with maximum effect. It is the place where the dynamic tension between opponents leads to transformation. The dynamic tension in all living systems is between similarity and difference. Chaos and complexity scholars recognized this tension as amounts of information. When the amounts of information were high, but not too high, the system moved to the edge of chaos, to the complexity regime, to strange attractors, or to chaos, depending on the model. The sweet spot is that range of relative variety, just the proper mix of similarity and difference, leading to transformation. This essay contains a model of human communication as an emergent social process with its own sweet spots. The essay also includes a description of current literature highlighting tensions between similarity and difference, and there is an exploration of the potential to move from one basin of attraction to another. The primary constraints on finding communication sweet spots are paradigmatic - adopting a process orientation, discovering the proper parameters, bracketing sequences to define initial conditions, and understanding the strengths and weaknesses of various modeling techniques.

    The so-called roll bar measurement uses a heavy metal material, optically thick to x-rays, to form a shadow of the x-ray origination spot. This spot is where an energetic electron beam interacts with a high Z target. The material (the "roll bar") is slightly curved to avoid alignment problems. The roll bar is constructed and positioned so that the x-rays are shadowed in the horizontal and vertical directions, so information is obtained in two dimensions. If a beam profile is assumed (or measured by other means), the equivalent x-ray spot size can be calculated from the x-ray shadow cast by the roll bar. Thus the ellipticity of the beam can be calculated, assuming the ellipse of the x-ray spot is aligned with the roll bar. The data is recorded using a scintillator and gated camera. Data will be presented from measurements using the ETA II induction LINAC. The accuracy of the measurement is checked using small elliptical targets.

    Most juvenile arrestees in custodial settings waive their Miranda rights almost immediately, and many then provide incriminating statements, if not outright confessions. Forensic practitioners are then asked to provide retrospective determinations regarding whether these waivers were effectuated knowingly, voluntarily, and intelligently. At present, the forensic assessment instrument for juvenile Miranda issues consists of the Miranda Rights Comprehension Instruments (MRCI)-which as its name implies-focuses mostly on Miranda comprehension with a de-emphasis of Miranda reasoning. In partially addressing this gap, the current study investigated the clinical utility of the Juvenile Miranda Quiz (JMQ) for evaluating key Miranda misconceptions, a critically important component of Miranda reasoning. Using data from 201 juvenile detainees, we evaluated the JMQ's discriminability with regards to cognitive variables and MRCI scales. Many moderate effect sizes in the predicted direction were found for the JMQ Primary Total and Juvenile Total scores. Finally, these detainees were tested using a mock crime scenario with a representative Miranda warning plus a brief interrogation to evaluate whether they would waive their rights, and if so, whether they would confess. Using Miranda measures to predict problematic outcomes (i.e., impaired waivers followed by confessions), the JMQ Juvenile Total proved the most successful. These findings are discussed within the context of the "intelligent" prong of Miranda waivers. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

  5. Spatial match-mismatch between juvenile fish and prey provides a mechanism for recruitment variability across contrasting climate conditions in the eastern Bering Sea.

    Directory of Open Access Journals (Sweden)

    Elizabeth Calvert Siddon

    Full Text Available Understanding mechanisms behind variability in early life survival of marine fishes through modeling efforts can improve predictive capabilities for recruitment success under changing climate conditions. Walleye pollock (Theragra chalcogramma support the largest single-species commercial fishery in the United States and represent an ecologically important component of the Bering Sea ecosystem. Variability in walleye pollock growth and survival is structured in part by climate-driven bottom-up control of zooplankton composition. We used two modeling approaches, informed by observations, to understand the roles of prey quality, prey composition, and water temperature on juvenile walleye pollock growth: (1 a bioenergetics model that included local predator and prey energy densities, and (2 an individual-based model that included a mechanistic feeding component dependent on larval development and behavior, local prey densities and size, and physical oceanographic conditions. Prey composition in late-summer shifted from predominantly smaller copepod species in the warmer 2005 season to larger species in the cooler 2010 season, reflecting differences in zooplankton composition between years. In 2010, the main prey of juvenile walleye pollock were more abundant, had greater biomass, and higher mean energy density, resulting in better growth conditions. Moreover, spatial patterns in prey composition and water temperature lead to areas of enhanced growth, or growth 'hot spots', for juvenile walleye pollock and survival may be enhanced when fish overlap with these areas. This study provides evidence that a spatial mismatch between juvenile walleye pollock and growth 'hot spots' in 2005 contributed to poor recruitment while a higher degree of overlap in 2010 resulted in improved recruitment. Our results indicate that climate-driven changes in prey quality and composition can impact growth of juvenile walleye pollock, potentially severely affecting

    Juvenile localized scleroderma comprises a group of autoimmune conditions often characterized clinically by an area of skin hardening. In addition to superficial changes in the skin and subcutaneous tissues, juvenile localized scleroderma may involve the deep soft tissues, bones and joints, possibly resulting in functional impairment and pain in addition to cosmetic changes. There is literature documenting the spectrum of findings for deep involvement of localized scleroderma (fascia, muscles, tendons, bones and joints) in adults, but there is limited literature for the condition in children. We aimed to document the spectrum of musculoskeletal magnetic resonance imaging (MRI) findings of both superficial and deep juvenile localized scleroderma involvement in children and to evaluate the utility of various MRI sequences for detecting those findings. Two radiologists retrospectively evaluated 20 MRI studies of the extremities in 14 children with juvenile localized scleroderma. Each imaging sequence was also given a subjective score of 0 (not useful), 1 (somewhat useful) or 2 (most useful for detecting the findings). Deep tissue involvement was detected in 65% of the imaged extremities. Fascial thickening and enhancement were seen in 50% of imaged extremities. Axial T1, axial T1 fat-suppressed (FS) contrast-enhanced and axial fluid-sensitive sequences were rated most useful. Fascial thickening and enhancement were the most commonly encountered deep tissue findings in extremity MRIs of children with juvenile localized scleroderma. Because abnormalities of the skin, subcutaneous tissues and fascia tend to run longitudinally in an affected limb, axial T1, axial fluid-sensitive and axial T1-FS contrast-enhanced sequences should be included in the imaging protocol.

    Lunar red spots are features on the nearside of the Moon that are characterized by high albedo and by a strong absorption in the ultraviolet. These red spots include the Gruithuisen domes, the Mairan domes, Hansteen Alpha, the southern portion of Montes Riphaeus, Darney Chi and Tau, Helmet, and an area near the Lassell crater. It has been suggested that many of the red spots are extrusive, nonmare, volcanic features that could be composed of an evolved lithlogy enriched in thorium. In fact, Hawke et al. used morphological characteristics to show that Hansteen Alpha is a nonmare volcanic construct. However, because the apparent Th abundances (6 - 7 ppm) were lower than that expected for evolved rock types, Hawke et al. concluded that Hansteen Alpha was composed of an unknown rock type. Subsequent studies by Lawrence et al. used improved knowledge of the Th spatial distribution for small area features on the lunar surface to revisit the interpretation of Th abundances at the Hansteen Alpha red spot. As part of their study, Lawrence et al. used a forward modeling technique to show that the Th abundance at Hansteen Alpha is not 6 ppm, but is more likely closer to 25 ppm, a value consistent with evolved lithologies. This positive correlation between the morphology and composition of Hansteen Alpha provides support for the presence of evolved lithologies on the lunar surface. It is possible, however, that Hansteen Alpha represents an isolated occurrence of non-mare volcanism. That is why we have chosen to use the forward modeling technique of Lawrence et al. to investigate the Th abundances at other lunar red spots, starting with the Gruithuisen domes. Additional information is included in the original extended abstract.

    Full Text Available The plastral spotting variation in the chelid turtle Phrynops hilarii (Duméril & Bibron, 1835 in relation to sex, size, and geographic procedence of individuals was analyzed. States for qualitative characters were analyzed using non-parametric tests. Quantitative characters (shell and scute measurements were standardized for body size by linear regression against carapace length, and were subjected to principal components analysis and canonical discriminant function analysis. Results suggest that increased plastral spotting is a polymorphic ontogenetic trait in P. hilarii. Neither hatchlings nor juveniles have plastral pattern moderately or heavily pigmented. The simplest pattern, however, may persist without changes in some adults. There are no differences between sexes. The spatial distribution of the plastral pattern is not ordered latitudinally or longitudinally, showing no relationship with gradients of elevation, temperature, or precipitation. This pattern trait lacks of taxonomic significance. The morphometric analysis failed to reveal any character of diagnostic utility in the plastron to support the possibility that these patterns correspond to different sympatric taxa.

    Reproductive biology and early life-history data are important for understanding the ecology of fishes. In 2008, we conducted captive propagation studies on 3 species of darters of the subgenus Nothonotus: Etheostoma wapiti (Boulder Darter), E. vulneratum (Wounded Darter), and E. maculatum (Spotted Darter). The length of spawning period and associated range of water temperatures for the Wounded Darter exceeded that of the Spotted Darter and Boulder Darter. The mean number of eggs produced per female was lowest for Boulder Darter and highest in the Wounded Darter. The Boulder Darter had the highest percent of eggs hatched, the lowest percent larval to juvenile stage survivorship, and the lowest mean number of juveniles produced per female. Egg diameters at deposition and prior to hatch were smallest for the Spotted Darter. If reproductive biology and early lifehistory information from captive fishes represent that of wild populations, then the data obtained during this study are relevant to development and implementation of conservation and management plans for these closely related darter species.

  12. Plasma spot welding of ferritic stainless steels

    2002-06-01

    Full Text Available Plasma spot welding of ferritic stainless steels is studied. The study was focused on welding parameters, plasma and shielding gases and the optimum welding equipment. Plasma-spot welded overlap joints on a 0.8 mm thick ferritic stainless steel sheet were subjected to a visual examination and mechanical testing in terms of tension-shear strength. Several macro specimens were prepared. Plasma spot welding is suitable to use the same gas as shielding gas and as plasma gas, i.e., a 98 % Ar/2 % H 2 gas mixture. Tension-shear strength of plasma-spot welded joints was compared to that of resistance-spot welded joints. It was found that the resistance welded joints withstand a somewhat stronger load than the plasma welded joints due to a larger weld spot diameter of the former. Strength of both types of welded joints is approximately the same.

    El artículo describe el proceso de soldeo de aceros inoxidables ferríticos por puntos con plasma. La investigación se centró en el establecimiento de los parámetros óptimos de la soldadura, la definición del gas de plasma y de protección más adecuado, así como del equipo óptimo para la realización de la soldadura. Las uniones de láminas de aceros inoxidables ferríticos de 0,8 mm de espesor, soldadas a solape por puntos con plasma, se inspeccionaron visualmente y se ensayaron mecánicamente mediante el ensayo de cizalladura por tracción. Se realizaron macro pulidos. Los resultados de la investigación demostraron que la solución más adecuada para el soldeo por puntos con plasma es elegir el mismo gas de plasma que de protección. Es decir, una mezcla de 98 % de argón y 2 % de hidrógeno. La resistencia a la cizalladura por tracción de las uniones soldadas por puntos con plasma fue comparada con la resistencia de las uniones soldadas por resistencia por puntos. Se llegó a la conclusión de que las uniones soldadas por resistencia soportan una carga algo mayor que la uniones

  17. Discovery of feature-based hot spots using supervised clustering

    2009-07-01

    Feature-based hot spots are localized regions where the attributes of objects attain high values. There is considerable interest in automatic identification of feature-based hot spots. This paper approaches the problem of finding feature-based hot spots from a data mining perspective, and describes a method that relies on supervised clustering to produce a list of hot spot regions. Supervised clustering uses a fitness function rewarding isolation of the hot spots to optimally subdivide the dataset. The clusters in the optimal division are ranked using the interestingness of clusters that encapsulate their utility for being hot spots. Hot spots are associated with the top ranked clusters. The effectiveness of supervised clustering as a hot spot identification method is evaluated for four conceptually different clustering algorithms using a dataset describing the spatial distribution of ground ice on Mars. Clustering solutions are visualized by specially developed raster approximations. Further assessment of the ability of different algorithms to yield hot spots is performed using raster approximations. Density-based clustering algorithm is found to be the most effective for hot spot identification. The results of the hot spot discovery by supervised clustering are comparable to those obtained using the G* statistic, but the new method offers a high degree of automation, making it an ideal tool for mining large datasets for the existence of potential hot spots.

    We use data from the two rounds of the NLSY97 and the corresponding QED data to examine the effectiveness of school endowments and curricula in targeting juvenile use of tobacco, alcohol, and marijuana. Our results support the notion that schools matter in reducing juvenile involvement in substance use. Higher discretionary dollars per pupil are linked to reduced rates of juvenile initiation and repetitive use rates of cigarettes and marijuana. Additionally, school curricula, as indicated by the implementation of year round classes and some innovative and after-school programs--such as gifted and talented, attendance monitoring, homework hotline, international baccalaureate, extended-day, and mentoring, programs, affect both juvenile initiation to tobacco and alcohol use and juvenile repetitive use of tobacco and alcohol. In particular, we find that juvenile initiation to cigarette use is approximately between 2 percentage points and 3 percentage points lower among youths attending schools with gifted and talented and international baccalaureate programs. In addition, juvenile repetitive cigarette use is approximately 54%, 52%, and 48% lower among youths attending schools offering year round classes, international baccalaureate, and twenty-first century programs, respectively. Finally, juvenile initiation to alcohol use and juvenile repetitive use of alcohol are approximately 3% and 20% lower, respectively, among youths in schools offering gifted and talented programs. In sum, while these programs are not implemented to address substance use problems among the student body, we find that the implementation of these programs is often accompanied by a reduction in juvenile initiation and repetitive substance use.

  20. Automated Spot Weld Inspection using Infrared Thermography

    Energy Technology Data Exchange (ETDEWEB)

    Chen, Jian [ORNL; Zhang, Wei [ORNL; Yu, Zhenzhen [ORNL; Feng, Zhili [ORNL

    2012-01-01

    An automated non-contact and non-destructive resistance spot weld inspection system based on infrared (IR) thermography was developed for post-weld applications. During inspection, a weld coupon was heated up by an auxiliary induction heating device from one side of the weld, while the resulting thermal waves on the other side were observed by an IR camera. The IR images were analyzed to extract a thermal signature based on normalized heating time, which was then quantitatively correlated to the spot weld nugget size. The use of normalized instead of absolute IR intensity was found to be useful in minimizing the sensitivity to the unknown surface conditions and environment interference. Application of the IR-based inspection system to different advanced high strength steels, thickness gauges and coatings were discussed.

  1. Brazilian spotted fever: a reemergent zoonosis

    2008-01-01

    Full Text Available Brazilian spotted fever is caused by the bacterium Rickettsia rickettsii, which is the most pathogenic species of the spotted-fever rickettsiae group and is transmitted by the bite of infected ticks. Amblyomma cajennense is the most important tick species involved in the cycle of this zoonosis in Brazil as it presents low host specificity, great number of natural reservoirs and wide geographic distribution. It was first described in the state of São Paulo in 1929 and later in Rio de Janeiro, Minas Gerais and Bahia. The number of cases decreased in the 1940's with the development of new plague control techniques and antibiotics. In the last decades, the number of new cases has increased. The current review aimed at reporting some of the epidemiological and public health aspects of this reemergent disease with new foci, mainly in the southeastern region of Brazil.

    We investigate high frequency price dynamics in foreign exchange market using data from Reuters information system (the dataset has been provided to us by Olsen and Associates). In our analysis we show that a naïve approach to the definition of price (for example using the spot mid price) may lead to wrong conclusions on price behavior as for example the presence of short term correlations for returns. For this purpose we introduce an algorithm which only uses the non arbitrage principle to estimate real prices from the spot ones. The new definition leads to returns which are not affected by spurious correlations. Furthermore, any apparent information (defined by using Shannon entropy) contained in the data disappears.

    Rocky Mountain spotted fever is a serious, generalized infection that is spread to humans through the bite of infected ticks. It can be lethal but it is curable. The disease gets its name from the Rocky Mountain region where it was first identified in 1896. The fever is caused by the bacterium Rickettsia rickettsii and is maintained in nature in a complex life cycle involving ticks and mammals. Humans are considered to be accidental hosts and are not involved in the natural transmission cycle of this pathogen. The author examined a 47-year-old woman during a periodic recall appointment. The patient had no dental problems other than the need for routine prophylaxis but mentioned a recent problem with swelling of her extremities with an accompanying rash and general malaise and soreness in her neck region. Tests were conducted and a diagnosis of Rocky Mountain spotted fever was made.

    Highlights: • A new high resolution laser induced oxidation (colouring) method is proposed (single spot oxidation). • The method is applied to control oxide films thicknesses and hence colours on titanium substrates in micro-scale. • The method enable imprinting high resolution coloured image on Ti substrate. • Optical and morphological periodic surface structures are also produced by an array of oxide spots using the proposed method. • Colour coding of two colours into one field is presented. - Abstract: Titanium oxides have a wide range of applications in industry, and they can be formed on pure titanium using different methods. Laser-induced oxidation is one of the most reliable methods due to its controllability and selectivity. Colour marking is one of the main applications of the oxidation process. However, the colourizing process based on laser scanning strategies is limited by the relative large processing area in comparison to the beam size. Single spot oxidation of titanium substrates is proposed in this research in order to increase the resolution of the processed area and also to address the requirements of potential new applications. The method is applied to produce oxide films with different thicknesses and hence colours on titanium substrates. High resolution colour image is imprinted on a sheet of pure titanium by converting its pixels’ colours into laser parameter settings. Optical and morphological periodic surface structures are also produced by an array of oxide spots and then analysed. Two colours have been coded into one field and the dependencies of the reflected colours on incident and azimuthal angles of the light are discussed. The findings are of interest to a range of application areas, as they can be used to imprint optical devices such as diffusers and Fresnel lenses on metallic surfaces as well as for colour marking.

    One way to get the fusion of hydrogen in laboratory consists in heating and compressing a DT fuel capsule by using a laser. To reach this aim requires a new generation of high power laser facility. Cea (French board for atomic energy) is developing for this purpose a new 240 laser line facility, the LMJ facility. The LIL which is the prototype of four LMJ laser lines is operational now. In order to confirm the technical choices, a systematic characterization of LIL was carried out. A particular effort has been provided to measure the 3{omega} high energy focal spot (1.5 kJ/700 ps and 5 ns for one beam) and the synchronization of laser beams onto the target, which are key issues for the plasma production. An experimental device, SAT-3{omega} (a 3{omega} laser focal spot analysis) has been designed to perform these measures. That diagnostic which is located at the end of the laser lines delivered its first results during the 2004 quadruplet qualification campaigns. The near field imaging showed no diaphony and vignetting. Low power spots allowed us to control we had no ghost. The energy measurement quality showed the photometric transfer function was perfectly known. Our caustic image are given with an average dynamic range of 800, a spatial resolution of 10 {mu}m and diameter accuracy about 1% for 50% and 3% for 90% of encircled energy. The high energy focal spot diameters are in agreement with low and very low energy diameters. The phase plate and 14 GHz effects are similar to what we had expected. For a laser shot completed with a continuous phase plate at 14 GHz, and for an energy level of 1.5 kJ per beam at 351 nm, the focal beam diameter at 3% of the peak level is (875 {+-} 45) {mu}m.

    Full Text Available A 3-month-old female patient with a giant ulcerated nodule over the back since birth was diagnosed as congenital giant juvenile xanthogranuloma (JXG based on clinical and histopathological examination. Congenital giant JXG with ulceration at birth is a rare presentation of JXG and commonly misdiagnosed. This case emphasizes the importance of being aware of the myriad presentations of JXG in order to make a correct diagnosis and avoid unnecessary investigations or treatment.

    Objective: Although not originally enacted to deter the problem of underage drinking in the United States, one set of laws that may influence this behavior is juvenile curfew laws. This research asked the following: (a) What is the effect of enacting a juvenile curfew law on youth drinking, and (b) do demographic variables moderate the relation between juvenile curfew law enactment and drinking? This study examined the effect of juvenile curfew laws on underage drinking, using data from 46 U.S. cities from 1991 to 2005. Method: In 2014, we compiled a data set containing alcohol and curfew law data by zip code. It included 63,081 minors (ages 12–17 years) from 1,081 zip codes. We used difference-in-difference regressions to analyze the data. Results: The effect of the enactment of a curfew law on the likelihood of consuming alcohol in the past year or past 30 days or of heavy episodic drinking in the past 2 weeks was not significant when compared with cities without curfew laws during the same periods. Although the likelihood of consuming alcohol over the past year differed depending on an individual’s characteristics (e.g., race/ethnicity, age, and gender), none of the interaction terms between these characteristics and curfew laws were significant. Conclusions: Curfew laws appear to have a non-significant effect on youth drinking, but these results are unclear without more knowledge as to where and when youth are drinking both before and after the enactment of curfew laws and how these laws are being enforced.

    2009-11-13

    Friction stir spot welding techniques were developed to successfully join several advanced high strength steels. Two distinct tool materials were evaluated to determine the effect of tool materials on the process parameters and joint properties. Welds were characterized primarily via lap shear, microhardness, and optical microscopy. Friction stir spot welds were compared to the resistance spot welds in similar strength alloys by using the AWS standard for resistance spot welding high strength steels. As further comparison, a primitive cost comparison between the two joining processes was developed, which included an evaluation of the future cost prospects of friction stir spot welding in advanced high strength steels.

    Full Text Available OBJECTIVE: To describe the clinical presentation a group of patients with juvenile onset of Huntington disease. METHOD: All patients were interviewed following a structured clinical questioner. Patients were genotyped for the trinucleotide cytosine-adenine-guanine (CAG repeat in the Huntington Disease gene. High resolution brain MRI was performed in all patients. RESULTS: We identified 4 patients with juvenile onset of disease among 50 patients with Huntington disease followed prospectively in our Neurogenetics clinic. Age at onset varied from 3 to 13 years, there were 2 boys, and 3 patients had a paternal inheritance of the disease. Expanded Huntington disease allele sizes varied from 41 to 69 trinucleotide repeats. The early onset patients presented with rigidity, bradykinesia, dystonia, dysarthria, seizures and ataxia. MRI showed severe volume loss of caudate and putamen nuclei (p=0.001 and reduced cerebral and cerebellum volumes (p=0.01. CONCLUSION: 8% of Huntington disease patients seen in our clinic had juvenile onset of the disease. They did not present with typical chorea as seen in adult onset Huntington disease. There was a predominance of rigidity and bradykinesia. Two other important clinical features were seizures and ataxia, which related with the imaging findings of early cortical atrophy and cerebellum volume loss.

    Full Text Available ABSTRACT: The prevalence of Juvenile idiopathic arthritis (JIA is 0.86 per 1000 children. Subcutaneous nodules have been reported in 5% to 10% of children with JIA. Approximately 90% of patients with RA and subc utaneous nodules test positive for rheumatoid factor (RF, and approximately 40% o f all RF-seropositive patients with RA have subcutaneous nodules, whereas only 6% in volvement is seen in seronegative cases. We hereby report a case of atypical Juvenile idiopathic arthritis (JIA in a 6 year old, female child with joint pain & myalgia along with subcutaneous nodules over the dorsum of feet, hands and elbows. Joint pain initial ly involving the left ankle, slowly progressed to involve the knee, shoulder, wrist, metacar pophalangeal and interphalangeal joints over a period of one year. Joint involvement was not symmetric. RF was Negative. Fundoscopy examination was normal. Histopathological examinat ion revealed a central zone of Fibrinoid necrosis surrounded by epithelioid h istiocytes and occasional lymphocytes. Differential diagnosis of Rheumatoid Nodule (R N or Subcutaneous Granuloma Annulare (SGA or Necrobiosis Lipoidica Diabeticorum was made. In light of clinicopathological findings, both SGA and NLD were ruled out a nd the diagnosis of Juvenile idiopathic arthritis presenting as RF-negative polyarthritis was made.

    Growing pressure to develop public lands for renewable energy production places several protected species at increased risk of habitat loss. One example is the Mojave desert tortoise (Gopherus agassizii), a species often at the center of conflicts over public land development. For this species and others on public lands, a better understanding of their habitat needs can help minimize negative impacts and facilitate protection or restoration of habitat. We used radio-telemetry to track 46 neonate and juvenile tortoises in the Eastern Mojave Desert, California, USA, to quantify habitat at tortoise locations and paired random points to assess habitat selection. Tortoise locations near burrows were more likely to be under canopy cover and had greater coverage of perennial plants (especially creosote [Larrea tridentata]), more coverage by washes, a greater number of small-mammal burrows, and fewer white bursage (Ambrosia dumosa) than random points. Active tortoise locations away from burrows were closer to washes and perennial plants than were random points. Our results can help planners locate juvenile tortoises and avoid impacts to habitat critical for this life stage. Additionally, our results provide targets for habitat protection and restoration and suggest that diverse and abundant small-mammal populations and the availability of creosote bush are vital for juvenile desert tortoises in the Eastern Mojave Desert.

    Few studies have longitudinally investigated the criminal profiles of violent juvenile sex and violent juvenile non-sex offenders. To make up for this lack, this study used police records of juveniles to determine the nature of the criminal profiles of violent sex offenders (n = 226) and violent non-sex offenders (n = 4,130). All offenders committed their first offense in 1996 and were followed for 7 years. Results showed that violent sex offenders and violent non-sex offenders cannot be considered a homogeneous group because of different background characteristics and criminal profiles. Sex and violent offenses often constitute a small part of a broader criminal pattern. Further research is necessary to reveal in more detail the developmental and criminological patterns of violent and sexual delinquency. Treatment and intervention programs may benefit from this.

    Richardson, Roger; Falabella, Steven; Guethlein, Gary; Raymond, Brett; Weir, John

    2005-01-01

    A diagnostic was developed for the determination of temporal history of an X-ray spot. A pair of thin (0.5 mm) slits image the x-ray spot to a fast scintillator which is coupled to a fast detector, thus sampling a slice of the X-Ray spot. Two other scintillator/detectors are used to determine the position of the spot and total forward dose. The slit signal is normalized to the dose and the resulting signal is analyzed to get the spot size. The position information is used to compensate for small changes due to spot motion and misalignment. The time resolution of the diagnostic is about 1 ns and measures spots from 0.5 mm to over 3 mm. The theory and equations used to calculate spot size and position are presented, as well as data. The calculations assume a symmetric, Gaussian spot. The spot data is generated by the ETA II accelerator, a 2kA, 5.5 MeV, 60ns electron beam focused on a Tantalum target. The spot generated is typically about 1 mm FWHM. Comparisons are made to an X-ray pinhole camera which images th...

    We report the results of the 2dF-VST ATLAS Cold Spot galaxy redshift survey (2CSz) based on imaging from VST ATLAS and spectroscopy from 2dF AAOmega over the core of the CMB Cold Spot. We sparsely surveyed the inner 5° radius of the Cold Spot to a limit of iAB ≤ 19.2, sampling ∼7000 galaxies at z data out to z ∼ 1, we conclude that the CMB Cold Spot could not have been imprinted by a void confined to the inner core of the Cold Spot. Additionally, we find that our 'control' field GAMA G23 shows a similarity in its galaxy redshift distribution to the Cold Spot. Since the GAMA G23 line of sight shows no evidence of a CMB temperature decrement, we conclude that the Cold Spot may have a primordial origin rather than being due to line-of-sight effects.

    We report a case of juvenile xanthogranuloma in a 12-month-old girl presenting with heterochromia, hyphema, and elevated intraocular pressure. This case demonstrates new ultrasound biomicroscopy iris findings of a generalized bumpy iris contour, suggesting diffuse heterogeneous involvement. This imaging finding has not been previously described. Untreated, iris juvenile xanthogranuloma may lead to corneal blood staining, glaucoma, and amblyopia. An understanding of the full range of ultrasound features of juvenile xanthogranuloma expands our appreciation for the clinical findings in this condition.

Also, the paper will statistically show the number of misdemeanors in the field of public peace and order that juveniles conducted in the Republic of Srpska in the period 2004-2009.

  12. Eliminating the Competency Presumption in Juvenile Delinquency Cases.

    Science.gov (United States)

    Katner, David R

    2015-01-01

    The legal presumption used in virtually all juvenile delinquency cases in the U.S. is that all juveniles are competent to stand trial. This Article calls for the elimination of that legal presumption, which is historically based on the Dusky v. United States decision and in the adult criminal justice system. The recent decisions of the U.S. Supreme Court recognize the developmental and organic brain differences between adults and juveniles. Current research demonstrates a higher frequency rate of incompetence based on intellectual deficiencies among children when compared with adults found to be not legally competent to stand trial. By eliminating the competency presumption for juveniles in both delinquency and adult criminal proceedings, the party seeking an adjudication would be responsible for establishing that the accused juvenile is in fact, competent to stand trial. Foreign jurisdictions in Europe, Asia, Africa, and South America have long required higher thresholds--at least fourteen years of age--for holding juveniles accountable for criminal misconduct, none of them presuming that juveniles are competent to go to trial. In the alternative, by expanding the factors currently in use for determination of juvenile competency by adding developmental immaturity and mental illness, juvenile justice systems could identify the reduction of recidivist offending as the primary systemic objective.

    Migration conveys an immense challenge, especially for juvenile birds coping with enduring and risky journeys shortly after fledging. Accordingly, juveniles exhibit considerably lower survival rates compared to adults, particularly during migration. Juvenile white storks (Ciconia ciconia), which are known to rely on adults during their first fall migration presumably for navigational purposes, also display much lower annual survival than adults. Using detailed GPS and body acceleration data, ...

  20. Uptake of Trace Elements in Aragonitic Otoliths of an Estuarine Dependent Fish, Spotted Seatrout, from surface waters of Chesapeake Bay.

    2002-05-01

    Seagrass beds in Chesapeake Bay are critical habitats for early life stages of Spotted seatrout, {\\Cynoscion nebulosus}. Spotted seatrout spawn in surface waters in the Bay during late spring and thereafter their larvae settle in seagrass beds where the juveniles spend three to four months. These habitats provide refuge and food for larvae and juveniles, influencing growth, mortality, and survival rates. Identification of essential seagrass habitats for estuarine-dependent fish is of primary importance given the current decline in habitat quality. We hypothesized that the geochemistry of surface waters in Chesapeake Bay is different along both the latitudinal and longitudinal gradients, and that we could use trace elements in otoliths as a natural tag to differentiate survivors among seagrass beds. We investigated the relationship between water and otolith trace element chemistry and we present here some preliminary results. From July to September 2001 we collected surface waters during spring tide from seagrass beds and around the mouth of the Potomac, Rappahannock, and York river. Waters were filtered through a 0.45 uM filter and acidified to pH < 2 with ultrapure nitric acid. In September, we collected juvenile fish in seagrass beds along the Western and Eastern shores, Tangier and Smith Islands. From each individual fish one sagittal otolith was extracted, cleaned with milli-Q water, soaked for 5 minutes in ultrapure hydrogen peroxide, rinsed, and sonicated. All dried and cleaned otoliths were dissolved in ultrapure nitric acid. We used trace metal clean procedures to process both water and otoliths and trace elements were measured by sector field ICP-MS. Both waters and otoliths showed distinct chemical signatures among seagrass beds, and samples could be classified with high accuracy to their respective sites of collection. For most seagrass beds Ba/Ca, Rb/Ca, V/Ca showed inverse relationship between water and otolith whereas Sr/Ca was positively correlated

    To reveal the accumulation profile of tetrodotoxin (TTX) in pufferfish Takifugu rubripes juveniles, we compared the localization of TTX in various tissues among wild juveniles and hatchery-reared juveniles with or without TTX administration using immunohistochemical technique with anti-TTX monoclonal antibody. Immuno-positive reaction was observed in hepatic tissue, basal cell of skin and olfactory, olfactory epithelium, optic nerve and brain (optic tectum, cerebellum, medulla oblongata) of wild juveniles (body length: BL, 4.7-9.4 cm). TTX was detected in the same tissues as wild juveniles and epithelial cell layer of intestine of hatchery-reared juveniles (BL, 5.0-5.3 cm) to which TTX was orally administrated. No positive reaction was observed from the tissues of hatchery-reared juveniles without TTX administration. These results suggest that orally administrated TTX to the non-toxic cultured juveniles is accumulated in the same manner of wild juveniles. In addition, our study revealed that pufferfish accumulates TTX in the central nervous system.

    2010-02-01

    Long-term juvenile growth patterns of tropical trees were studied to test two hypotheses: fast-growing juvenile trees have a higher chance of reaching the canopy ('juvenile selection effect'); and tree growth has increased over time ('historical growth increase'). Tree-ring analysis was applied to test these hypotheses for five tree species from three moist forest sites in Bolivia, using samples from 459 individuals. Basal area increment was calculated from ring widths, for trees rings formed by small juveniles. Thus, extant adult trees in these species have had higher juvenile growth rates than extant juvenile trees. By contrast, rings formed by somewhat larger juveniles in four species showed the opposite pattern: a historical growth increase. For most size classes of > 10 cm diameter none of the patterns was found. Fast juvenile growth may be essential to enable tropical trees to reach the forest canopy, especially for small juvenile trees in the dark forest understorey. The historical growth increase requires cautious interpretation, but may be partially attributable to CO(2) fertilization.

    Spot welding is a type of resistance welding in which pieces of metals are pressed together and an electric current is passed through them. Spot welders are at risk of contact with some potentially hazardous agents but there are few studies about the respiratory effects of spot welding. Our objective was to study lung function and respiratory symptoms among spot welders and office workers at an automobile assembly factory in Iran. This was a cross-sectional study of 137 male spot welders and 129 office workers. We used a questionnaire to record demographic data, smoking habits, work history and respiratory symptoms. Spirometry was performed to assess lung function status. Metal fume samples from the respiratory zone of spot welders were analysed. The concentrations of metal fume were less than the American Conference of Industrial Hygienists (ACGIH) threshold limit values. There were significantly lower values for average forced expiratory volume in 1st second (FEV(1)), FEV(1)/forced vital capacity and 25-75% forced expiratory flow in spot welders compared to controls. There was also a significantly raised prevalence of respiratory symptoms (sputum and dyspnoea) in spot welders. Fifteen per cent of spot welders and 1% of controls had an obstructive pattern in spirometry. Our survey suggests that spot welders are at risk of developing respiratory symptoms and decreasing pulmonary function values despite their exposure to components of welding fume being within ACGIH guidelines.

  4. The fractal nature of vacuum arc cathode spots

    Energy Technology Data Exchange (ETDEWEB)

    Anders, Andre

    2005-05-27

    Cathode spot phenomena show many features of fractals, for example self-similar patterns in the emitted light and arc erosion traces. Although there have been hints on the fractal nature of cathode spots in the literature, the fractal approach to spot interpretation is underutilized. In this work, a brief review of spot properties is given, touching the differences between spot type 1 (on cathodes surfaces with dielectric layers) and spot type 2 (on metallic, clean surfaces) as well as the known spot fragment or cell structure. The basic properties of self-similarity, power laws, random colored noise, and fractals are introduced. Several points of evidence for the fractal nature of spots are provided. Specifically power laws are identified as signature of fractal properties, such as spectral power of noisy arc parameters (ion current, arc voltage, etc) obtained by fast Fourier transform. It is shown that fractal properties can be observed down to the cutoff by measurement resolution or occurrence of elementary steps in physical processes. Random walk models of cathode spot motion are well established: they go asymptotically to Brownian motion for infinitesimal step width. The power spectrum of the arc voltage noise falls as 1/f {sup 2}, where f is frequency, supporting a fractal spot model associated with Brownian motion.

  5. Count response model for the CMB spots

    2010-01-01

    The statistics of the curvature quanta generated during a stage of inflationary expansion is used to derive a count response model for the large-scale phonons determining, in the concordance lore, the warmer and the cooler spots of the large-scale temperature inhomogeneities. The multiplicity distributions for the counting statistics are shown to be generically overdispersed in comparison with conventional Poissonian regressions. The generalized count response model deduced hereunder accommodates an excess of correlations in the regime of high multiplicities and prompts dedicated analyses with forthcoming data collected by instruments of high angular resolution and high sensitivity to temperature variations per pixel.

    Petroni, Filippo; Serva, Maurizio

    2004-12-01

    In this work we discuss the problem of price definition when using high frequency foreign exchange data. If one uses the spot mid price a strong autocorrelation of returns, at one lag, is found which is only due to microstructure effect and does not capture the real behavior of price dynamics. This autocorrelation increases the intraday volatility estimated from this type of data. To solve this problem we introduce an algorithm which is able, by using the no-arbitrage principle, of eliminating every microstructure effects.

    2008-09-01

    Full Text Available Abstract Background Image analysis of microarrays and, in particular, spot quantification and spot quality control, is one of the most important steps in statistical analysis of microarray data. Recent methods of spot quality control are still in early age of development, often leading to underestimation of true positive microarray features and, consequently, to loss of important biological information. Therefore, improving and standardizing the statistical approaches of spot quality control are essential to facilitate the overall analysis of microarray data and subsequent extraction of biological information. Findings We evaluated the performance of two image analysis packages MAIA and GenePix (GP using two complementary experimental approaches with a focus on the statistical analysis of spot quality factors. First, we developed control microarrays with a priori known fluorescence ratios to verify the accuracy and precision of the ratio estimation of signal intensities. Next, we developed advanced semi-automatic protocols of spot quality evaluation in MAIA and GP and compared their performance with available facilities of spot quantitative filtering in GP. We evaluated these algorithms for standardised spot quality analysis in a whole-genome microarray experiment assessing well-characterised transcriptional modifications induced by the transcription regulator SNAI1. Using a set of RT-PCR or qRT-PCR validated microarray data, we found that the semi-automatic protocol of spot quality control we developed with MAIA allowed recovering approximately 13% more spots and 38% more differentially expressed genes (at FDR = 5% than GP with default spot filtering conditions. Conclusion Careful control of spot quality characteristics with advanced spot quality evaluation can significantly increase the amount of confident and accurate data resulting in more meaningful biological conclusions.

    Leatherback turtles, Dermochelys coriacea, which have an irregular pink area on the crown of the head known as the pineal or ‘pink spot’, forage upon jellyfish in cool temperate waters along the western and eastern margins of the North Atlantic during the summer. Our study showed that the skeletal structures underlying the pink spot in juvenile and adult turtles are compatible with the idea of a pineal dosimeter function that would support recognition of environmental light stimuli. We interrogated an extensive turtle sightings database to elucidate the phenology of leatherback foraging during summer months around Great Britain and Ireland and compared the sightings with historical data for sea surface temperatures and day lengths to assess whether sea surface temperature or light periodicity/levels were likely abiotic triggers prompting foraging turtles to turn south and leave their feeding grounds at the end of the summer. We found that sea temperature was too variable and slow changing in the study area to be useful as a trigger and suggest that shortening of day lengths as the late summer equilux is approached provides a credible phenological cue, acting via the pineal, for leatherbacks to leave their foraging areas whether they are feeding close to Nova Scotia or Great Britain and Ireland.

    Thermal stability is essential for the survival and well-being of preterm neonates. This is achieved in neonatal incubators by raising the ambient temperature and humidity to sufficiently high levels. However, potentially pathogenic microorganisms also can thrive in such warm and humid environments. We therefore investigated whether the level of microbial contamination (i.e., the bacterial load) inside neonatal incubators can be predicted on the basis of their average temperature and relative humidity settings, paying special attention to local temperature differences. Swab samples were taken from the warmest and coldest spots found within Caleo incubators, and these were plated to determine the number of microbial CFU per location. In incubators with high average temperature (≥ 34°C) and relative humidity (≥ 60%) values, the level of microbial contamination was significantly higher at cold spots than at hot spots. This relates to the fact that the local equilibrium relative humidity at cold spots is sufficiently high to sustain microbial growth. The abundance of staphylococci, which are the main causative agents of late-onset sepsis in preterm neonates, was found to be elevated significantly in cold areas. These findings can be used to improve basic incubator hygiene.

    1979-01-01

    A 2-year-old girl was treated with gold salts for juvenile rheumatoid arthritis. Treatment had to be discontinued when persistent proteinuria was detected. As this case report indicates, close monitoring of the urine is mandatory during treatment with gold salts to detect early signs of toxicity: hematuria followed by casts and then proteinuria as therapy is continued. Histologic examination with electron microscopy will help to differentiate the different forms of gold toxicity. When the findings are consistent with gold-induced renal involvement, therapy should be discontinued. The gold nephropathy usually resolves in time, with no permanent renal damage.

    Paediatric rheumatology is a relatively new specialty that has developed rapidly over the last 30 years. There have been major advances, which have included improvements in the classification and management of juvenile idiopathic arthritis (JIA). The former has led to enhanced international collaboration with disease registries, multicentre research and the development of new therapeutic agents. This has resulted in improved disease control and remission induction in many. There is, however, still significant morbidity associated with JIA during childhood, adolescence and adulthood, and challenges for the future include early identification of those with a poorer prognosis, appropriate administration of safe therapies and optimizing outcomes as young people move through adolescence into adulthood.

    2016-03-01

    Juvenile psammomatoid ossifying fibroma (JPOF) is a fibroosseous tumor that arises in the craniofacial bones in young people. This lesion usually originates in the jaw, orbit, and ethmoid complex but can also be associated with the skull base and calvaria. Diagnosis must be made based on observing typical radiological and histopathological features. Although JPOF is a rare pathological entity, neurosurgeons must consider this odontogenic lesion in the differential diagnosis of skull masses given the lesion's aggressive behavior and locally invasive growth. Treatment must be gross-total resection. In the following article, the authors present a case of cranial JPOF and discuss various aspects of this entity.

    The chronic arthritides in childhood remain a poorly understood group of conditions. Their classification has been a source of much confusion over the years with differences in terminology between Europe and North America. A significant step forward in paediatric rheumatology has been the recent development of an internationally agreed classification system which uses the overall term juvenile idiopathic arthritis (JIA). The various subtypes of JIA and their clinical features are described, together with an overview of their differential diagnosis, complications and outcomes. An outline of current management strategies is given and potential future developments highlighted.

  3. Spinning-Spot Shadowless TIRF Microscopy.

    Directory of Open Access Journals (Sweden)

    Kyle L Ellefsen

    Full Text Available Total internal reflection fluorescence (TIRF microscopy is a powerful tool for visualizing near-membrane cellular structures and processes, including imaging of local Ca2+ transients with single-channel resolution. TIRF is most commonly implemented in epi-fluorescence mode, whereby laser excitation light is introduced at a spot near the periphery of the back focal plane of a high numerical aperture objective lens. However, this approach results in an irregular illumination field, owing to interference fringes and scattering and shadowing by cellular structures. We describe a simple system to circumvent these limitations, utilizing a pair of galvanometer-driven mirrors to rapidly spin the laser spot in a circle at the back focal plane of the objective lens, so that irregularities average out during each camera exposure to produce an effectively uniform field. Computer control of the mirrors enables precise scanning at 200 Hz (5ms camera exposure times or faster, and the scan radius can be altered on a frame-by-frame basis to achieve near-simultaneous imaging in TIRF, widefield and 'skimming plane' imaging modes. We demonstrate the utility of the system for dynamic recording of local inositol trisphosphate-mediated Ca2+ signals and for imaging the redistribution of STIM and Orai proteins during store-operated Ca2+ entry. We further anticipate that it will be readily applicable for numerous other near-membrane studies, especially those involving fast dynamic processes.

    1994-09-01

    As more powerful solid state laser sources appear on the market, new applications become technically possible and important from the economical point of view. For every process a preliminary optimization phase is necessary. The main parameters, used for a welding application by a high power Nd-YAG laser, are: pulse energy, pulse width, repetition rate and process duration or speed. In this paper an experimental methodology, for the development of an electrooptical laser spot welding monitoring system, is presented. The electromagnetic emission from the molten pool was observed and measured with appropriate sensors. The statistical method `Parameter Design' was used to obtain an accurate analysis of the process parameter that influence process results. A laser station with a solid state laser coupled to an optical fiber (1 mm in diameter) was utilized for the welding tests. The main material used for the experimental plan was zinc coated steel sheet 0.8 mm thick. This material and the related spot welding technique are extensively used in the automotive industry, therefore, the introduction of laser technology in production line will improve the quality of the final product. A correlation, between sensor signals and `through or not through' welds, was assessed. The investigation has furthermore shown the necessity, for the modern laser production systems, to use multisensor heads for process monitoring or control with more advanced signal elaboration procedures.

  6. Laser induced single spot oxidation of titanium

    Titanium oxides have a wide range of applications in industry, and they can be formed on pure titanium using different methods. Laser-induced oxidation is one of the most reliable methods due to its controllability and selectivity. Colour marking is one of the main applications of the oxidation process. However, the colourizing process based on laser scanning strategies is limited by the relative large processing area in comparison to the beam size. Single spot oxidation of titanium substrates is proposed in this research in order to increase the resolution of the processed area and also to address the requirements of potential new applications. The method is applied to produce oxide films with different thicknesses and hence colours on titanium substrates. High resolution colour image is imprinted on a sheet of pure titanium by converting its pixels' colours into laser parameter settings. Optical and morphological periodic surface structures are also produced by an array of oxide spots and then analysed. Two colours have been coded into one field and the dependencies of the reflected colours on incident and azimuthal angles of the light are discussed. The findings are of interest to a range of application areas, as they can be used to imprint optical devices such as diffusers and Fresnel lenses on metallic surfaces as well as for colour marking.

    2013-01-01

    We present an updated analysis of Jupiter's equatorial meteorology from Cassini observations. For two months preceding the spacecraft's closest approach, the Imaging Science Subsystem (ISS) onboard regularly imaged the atmosphere. We created time-lapse movies from this period in order to analyze the dynamics of equatorial hot spots and their interactions with adjacent latitudes. Hot spots are quasi-stable, rectangular dark areas on visible-wavelength images, with defined eastern edges that sharply contrast with surrounding clouds, but diffuse western edges serving as nebulous boundaries with adjacent equatorial plumes. Hot spots exhibit significant variations in size and shape over timescales of days and weeks. Some of these changes correspond with passing vortex systems from adjacent latitudes interacting with hot spots. Strong anticyclonic gyres present to the south and southeast of the dark areas appear to circulate into hot spots. Impressive, bright white plumes occupy spaces in between hot spots. Compact...

  2. Spatial dynamics of juvenile anchovy in the Bay of Biscay

    KAUST Repository

    Boyra, Guillermo

    2016-07-08

    In autumn 2009, the implementation of two successive acoustic surveys targeting juvenile anchovy (Engraulis encrasicolus) in the Bay of Biscay allowed us to monitor the changes in the spatial distribution and aggregation patterns of juveniles of this species during 45 days under fairly stable meteorological conditions. Juvenile anchovy changed its biological condition and behavior in a different manner in two distinct areas. In the Spanish sector, the juveniles migrated 20 nautical miles (n.mi.) towards the coast, but they remained on the shelf and near the surface during the whole surveyed period. As the advance towards the shelf break progressed, their area of distribution decreased, their density increased and the juveniles spread in fewer but heavier shoals. In the French sector, the juveniles also migrated from slope waters towards the coast at a similar velocity, but they crossed the shelf break into the continental shelf, where they increased their mean depth significantly until gradually adopting the typical nyctemeral migrations of adult anchovy. The mean length of the juveniles that adopted the nyctemeral migrations was significantly higher than that of the juveniles remaining at the surface, suggesting that body size is relevant to accomplish this change. Besides, the stronger temperature gradients between the shelf and oceanic waters in the Spanish sector, favored by a narrow shelf, may have acted as a barrier influencing the distinct observed spatial patterns in the two areas. © 2016 John Wiley & Sons Ltd

    Bier spots are small, irregular, hypopigmented macules that are usually found on the arms and legs. The macules disappear when the limb is raised. Bier spots have been reported in association with a number of conditions but there is no consistent association to specific desease. Although they usually affect young adults, we report a case of Bier spots that began in childhood. As an asymptomatic and possibly transitional condition, the disease does not require treatment.

    Analysis of selected studbook records of the American Paint Horse Association, consisting of 687 foals sired by 13 overo stallions from non-overo mares, supports the inheritance of overo spotting as an autosomal dominant gene. More than one gene may control patterns registered as overo. Additional studies are necessary to explain the sporadic occurrence of overo spotting from nonspotted quarter horse parents and to confirm the inheritance of overo spotting in other breeds.

    Recent advances in spot-welding technology such as high frequency direct current inverter welders provide an improved and reproducible method to spot-weld difficult junctions. The importance of removing the oxide layers on metal surfaces, accurately delivering the weld pulse profile, and controlling the force applied to the materials during the welding process are discussed in the context of resistance spot-welding a molybdenum crystal to a tantalum loop and attaching a tungsten-rhenium thermocouple to the crystal.

    Understanding the dynamics of spot interest rates is important for derivatives pricing, risk management, interest rate liberalization, and macroeconomic control. Based on a daily data of Chinese 7-day repo rates from July 22, 1996 to August 26, 2004, we estimate and test a variety of popular spot rate models, including single factor diffusion, GARCH, Markov regime switching and jump diffusion models, to examine how well they can capture the dynamics of the Chinese spot rates and whether the d...

    Objective. Cardiovascular disease is associated with inflammation and immune activation, concentrations of immune activation markers like neopterin predict outcome in adults. Methods. Serum neopterin concentrations and early metabolic and pre-atherosclerotic symptoms were analyzed in 295 obese juveniles and 101 normal weight controls of similar age. Additionally, the influence of a 12 months weight reduction program on neopterin levels was investigated in 31 obese juveniles. Results. Intima-media thickness of common carotid arteries (IMT) and the concentrations of C-reactive protein (CRP) were increased in the obese juveniles (P juveniles (P juvenile obesity behaved considerably different from what was demonstrated in adults, levels did not correlate with metabolic and pre-atherosclerotic symptoms found in early phases although early vascular burden and chronic low grade inflammation was indicated by increased IMT and CRP. Neopterin concentrations increased after a 12 months intervention program.

    Full Text Available Dramatic events of year 587/586 triggered off a new way of thinking of Israelites over their history. It helped to think about resurrection not only in a traditional way – a ruler from the House of David, the King–Messiah and the Shepherd–Messiah. The lacks of political independence made people think of a new Kingdom. They were looking for a nationalist Messiah, who would realistically restore the kingdom of David and Salomon. The Son of Man, through his deep relationship with God, expressed a longing for ideal Kingdom, where God can reign. The Messiah, just and chosen by God, would represent those, who saw Israel as a great Kingdom of Israel, perfectly keeping the Law and living in peace. The Son of God, mysterious pre-existent Messiah, represents those, who yearn for a new and great leader, who is supported by almighty God and who would restore a worldly, wonderful Kingdom.

    2002-08-01

    A fatigue crack can be effectively retarded by heating a spot near the crack tip under nil remote stress condition. The subcritical spot heating at a proper position modifies the crack growth behaviour in a way, more or less, similar to specimen subjected to overload spike. It is observed that the extent of crack growth retardation increases with increasing level of overload as well as with increasing spot temperature. It is also observed that modification in crack growth behaviour is a function of location of heating spot and maximum retardation is observed at + 5 position.

  18. Factors influencing predation on juvenile ungulates and natural selection implications

    Directory of Open Access Journals (Sweden)

    S. M. Barber-Meyer

    2008-06-01

    Full Text Available Juvenile ungulates are generally more vulnerable to predation than are adult ungulates other than senescent individuals, not only because of their relative youth, fragility, and inexperience, but also because of congenital factors. Linnell et al.’s (Wildl. Biol. 1: 209-223 extensive review of predation on juvenile ungulates concluded that research was needed to determine the predisposition of these juveniles to predation. Since then, various characteristics that potentially predispose juvenile ungulates have emerged including blood characteristics, morphometric and other condition factors, and other factors such as birth period, the mother’s experience, and spatial and habitat aspects. To the extent that any of the physical or behavioral traits possessed by juvenile ungulates have a genetic or heritable and partly independent epigenetic component that predisposes them to predation, predators may play an important role in their natural selection. We review the possible influence of these characteristics on predisposing juvenile ungulates to predation and discuss natural selection implications and potential selection mechanisms. Although juvenile ungulates as a class are likely more vulnerable to predation than all but senescent adults, our review presents studies indicating that juveniles with certain tendencies or traits are killed more often than others. This finding suggests that successful predation on juveniles is more selective than is often assumed. Because we are unable to control for (or in some cases even measure the myriad of other possible vulnerabilities such as differences in sensory abilities, intelligence, hiding abilities, tendency to travel, etc., finding selective predation based on the relatively few differences we can measure is noteworthy and points to the significant role that predation on juveniles has in the natural selection of ungulates. Future research should compare characteristics, especially those known to

    Juvenile dermatomyositis is the leading cause of chronic idiopathic inflammatory myopathy of auto-immune origin in children. Lung involvement in inflammatory myopathies is well described in adults, involving mostly interstitial lung disease, aspiration pneumonia and alveolar hypoventilation. We propose to describe its specificities in children. Pulmonary involvement may be asymptomatic and therefore must be systematically screened for. In case of clinical or functional respiratory abnormality, a chest computed tomographic (CT) scan is necessary. In children, a decrease of respiratory muscle strength seems common and should be systematically and specifically searched for by non-invasive and reproducible tests (sniff test). Interstitial lung disease usually associates restrictive functional defect, impairment of carbon monoxide diffusion and interstitial lung disease on CT scan. As in adults, the first-line treatment of juvenile dermatomyositis is based on corticosteroids. Corticosteroid resistant forms require corticosteroid bolus or adjuvant immunosuppressive drugs (methotrexate or cyclosporine). There is no consensus in pediatrics for the treatment of diffuse interstitial lung disease. Complications of treatment, including prolonged steroid therapy, are frequent and therefore a careful assessment of the treatments risk-benefit ratio is necessary, especially in growing children.

    2017-09-01

    Assessment of development is an important component of age estimation in juveniles. One area that has not been fully investigated as a possible aging method is the development of the frontal sinus. The frontal sinuses form when the ectocranial table of the frontal bone separates from the endocranial table forming an air pocket in the bone. The endocranial table ceases growth with the brain, while the ectocranial table is displaced anteriorly as the facial bones continue growth. In order to examine growth and the utility of the frontal sinuses for age estimation, 392 radiographs were examined (♀=159 and ♂=233) from the Juvenile Radiograph Database at North Carolina State University and the Patricia Database from Mercyhurst University. The sample included individuals who ranged in age from 0 to 18 years. Anterior view (or AP) radiographs were examined and were grouped based upon the presence or absence of the frontal sinus. Individuals were grouped into four age categories. A one-way ANOVA was performed to test whether developmental phase was related to age. Results from the ANOVA show that developmental phase is significantly related to age (P Anat Rec, 300:1609-1617, 2017. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

Sin embargo, factores clásicos asociados al origen social o al mundo del trabajo no alcanzan para comprender la diferenciación en los modos de inserción. Este artículo propone la inclusión de las temporalidades juveniles como factor clave para la comprensión de trayectorias laborales de jóvenes. Las temporalidades juveniles sirven para observar conjuntamente los marcos temporales dominantes de la inserción y la manera en la que los mismos son vividos por los sujetos. Las mismas discuten las tesis que señalan que en Argentina los jóvenes son prisioneros de un presentismo sin proyecto o que se someten inevitablemente a un contexto laboral incierto. Cuatro tipo des temporalidades han emergido en el análisis cualitativo y longitudinal de las trayectorias : los "planificadores", los "ejecutantes", los "latentes" y los "oportunistas"

    2016-09-01

    Systemic-onset juvenile idiopathic arthritis (SoJIA) is a systemic inflammatory disease which has up to now been classified as a category of juvenile idiopathic arthritis. However, in this context, systemic inflammation has been associated with dysregulation of the innate immune system, suggesting that it may rather be part of the spectrum of autoinflammatory disorders. The disease is in fact unique with regard to the other JIA categories, in terms of clinical manifestations, prognosis, and response to conventional immunosuppressant therapies. It is characterized clinically by fever, lymphadenopathy, arthritis, rash, and serositis. IL-1 and IL-6 play a major role in the pathogenesis of SoJIA, and treatment with IL-1 and IL-6 inhibitors has shown to be highly effective. However, complications of SoJIA, including macrophage activation syndrome, limitations in functional outcome by arthritis and long-term damage from chronic inflammation continue to be a major issue in patients' care. Recent advances on the pathogenesis and treatment have revolutionized the care and prognosis of this potentially life-threatening pediatric condition.

    Juvenile idiopathic arthritis (JIA), as a chronic condition, is associated with significant disease- and treatment-related morbidity, thus impacting children's quality of life. In order to optimize JIA management, the paediatric rheumatologist has begun to regularly use measurements of disease activity developed, validated and endorsed by international paediatric rheumatology professional societies in an effort to monitor the disease course over time and assess the efficacy of therapeutic interventions in JIA patients.A literature review was performed to describe the main outcome measures currently used in JIA patients to determine disease activity status.The Juvenile Disease Activity Score (JADAS), in its different versions (classic JADAS, JADAS-CRP and cJADAS) and the validated definitions of disease activity and response to treatment represent an important tool for the assessment of clinically relevant changes in disease activity, leading more and more to a treat-to-target strategy, based on a tight and thorough control of the patient condition. Moreover, in recent years, increasing attention on the incorporation of patient-reported or parent-reported outcomes (PRCOs), when measuring the health state of patients with paediatric rheumatic diseases has emerged.We think that the care of JIA patients cannot be possible without taking into account clinical outcome measures and, in this regard, further work is required.

    Bilateral chronic anterior uveitis is an extra-articular feature of juvenile idiopathic arthritis. Although figures vary, uveitis occurs in approximately 11%-13% of patients with this disease and is most commonly associated with the female gender, oligoarthritis, and presence of antinuclear antibodies. The disease has an insidious onset and is often asymptomatic. Managing patients with juvenile idiopathic arthritis-associated uveitis remains challenging as the disease may prove to be refractory to traditional treatment regimens. Stepwise immunomodulatory therapy is indicated, with new biologic drugs being used last in cases of refractory uveitis. Small scale studies and practice have provided the evidence to undertake randomized control trials to evaluate the efficacy, safety, and cost-effectiveness of anti-tumor necrosis factor-α therapies, such as infliximab and adalimumab. These have demonstrated promising results, with further data awaited from ongoing trials for adalimumab (as SYCAMORE and ADJUVITE trials). Lower grade evidence is supporting the use of newer biologics such as rituximab, daclizumab, tocilizumab, and abatacept in those cases refractory to anti-tumor necrosis factor-α therapy.

    Full Text Available Juvenile cellulitis or juvenile sterile granulomatous lymphadenitis is a rare disorder that affects puppies between three weeks to six months years old. Clinical signs include alopecia, edema, papules, pustules and crusts especially on eyelids. Definitive diagnosis requires cytological and histological evaluation and early and aggressive therapy is recommended, once scars after recovery can be severe .The choice treatment is the high dose of corticosteroids use such as prednisone. Three animals of canine species were attended at the Veterinary Hospital Clinical Small Animal Service presenting different clinical signs. Hemogram, skin lesions and submandibular lymph nodes cytological examination was collected and analyzed. The treatment was instituted, using cephalexin (22mg/kg, twice daily up to control of secondary bacterial infection, and prednisone (2mg/kg, once a day until clinical resolution. Complete cure was obtained at the end of treatment. The aim of this work is to report three clinical cases of juvenile cellulitis in dogs.

    Powernext SA is a Multilateral Trading Facility in charge of managing the French power exchange through an optional and anonymous organised exchange. Powernext started operating on 27 November 2001. Although the German exchange, EEX, has been functioning for much longer, the two have many common points. Both use the same system for fixing the day-ahead spot price, the one developed by NordPool. In contrast to Omel in Spain, power producers in France and Germany are not obliged to sell through the exchange. In addition, the cross-border transmission lines that physically link the French and German grids, not only make the electricity supply more reliable they also allow cross-border commercial transactions which should homogenize prices in both countries. So after nearly a year of operation it is interesting to compare the spot prices on the two exchanges in order to have a better understanding of the statistical properties of the prices in the two markets and the relationship between them. This information will be used when modelling the structure of the day-ahead spot prices. The data used to carry out the study consists of the (hourly) spot prices for electricity from Powernext and EEX, for the period from 1 January 2002 to 2 December 2002. Data from the first five weeks of trading were not included because traded volumes were relatively low initially and so these data are not necessarily representative. This report is divided into four sections. The first one presents the basic statistics, starting with the histograms of all the 8064 spot prices in the 336 days, for both exchanges. In time series data, it is usual to find three types of seasonality: daily, weekly and annual. As the available data cover less than one calendar year, it is too early to attempt to study annual trends. So we limit ourselves to studying daily and weekly fluctuations. Plotting the hourly average prices for each day of the week shows some interesting differences between Powernext and

    Numerous features of glaciological significance appear on two adjoining SPOT High Resolution Visible (HRV) images that cover the onset region of ice stream B. Many small-scale features, such as crevasses and drift plumes, have been previously observed in aerial photography. Subtle features, such as long flow traces that have not been mapped previously, are also clear in the satellite imagery. Newly discovered features include ladder-like runners and rungs within certain shear margins, flow traces that are parallel to ice flow, unusual crevasse patterns, and flow traces originating within shear margins. An objective of our work is to contribute to an understanding of the genesis of the features observed in satellite imagery. The genetic possibilities for flow traces, other lineations, bands of transverse crevasses, shear margins, mottles, and lumps and warps are described.

    The main payload of the BIRD micro-satellite is the newly developed hot spot recognition system. It's a dual-channel instrument for middle and thermal infrared imagery based on cooled MCT line detectors. The miniaturisation by integrated detector/cooler assemblies provides a highly efficient design. Since the launch in October 2001 from SHAR/India the BIRD payload, claiming 30% of the BIRD mass of 92 kg, is fully operational. Among others forest fires (Australia), volcanoes (Etna, Chile) and burning coal mines (China) have been detected and their parameters like size, temperature and energy release could be determined. As the status of the payload system is satisfactorily it has a potential to be applied in new missions with the help of modern detector technology.

    Rainfall simulator trials were conducted on sugar cane paddocks across dry-tropical and subtropical Queensland, Australia, to examine the potential for spot spraying to reduce herbicide losses in runoff. Recommended rates of the herbicides glyphosate, 2,4-D, fluoroxypyr, atrazine, and diuron were sprayed onto 0, 20, 40, 50, 70, or 100% of the area of runoff plots. Simulated rainfall was applied 2 days after spraying to induce runoff at one plant cane and three ratoon crop sites. Over 50% of all herbicides were transported in the dissolved phase of runoff, regardless of the herbicide's sediment-water partition coefficient. For most sites and herbicides, runoff herbicide concentrations decreased with decreasing spray coverage and with decreasing herbicide load in the soil and cane residues. Importantly, sites with higher infiltration prior to runoff and lower total runoff had lower runoff herbicide concentrations.

  15. Magnetic spots on hot massive stars

    CERN Document Server

    Cantiello, Matteo

    2011-01-01

    Hot luminous stars show a variety of phenomena in their photospheres and winds which still lack clear physical explanation. Among these phenomena are photospheric turbulence, line profile variability (LPV), non-thermal emission, non-radial pulsations, discrete absorption components (DACs) and wind clumping. Cantiello et al. (2009) argued that a convection zone close to the stellar surface could be responsible for some of these phenomena. This convective zone is caused by a peak in the opacity associated with iron-group elements and is referred to as the "iron convection zone" (FeCZ). Assuming dynamo action producing magnetic fields at equipartition in the FeCZ, we investigate the occurrence of subsurface magnetism in OB stars. Then we study the surface emergence of these magnetic fields and discuss possible observational signatures of magnetic spots. Simple estimates are made using the subsurface properties of massive stars, as calculated in 1D stellar evolution models. We find that magnetic fields of suffici...

    The spot characteristics for proton pencil beam scanning (PBS) were measured and analyzed over a 16 month period, which included one major site configuration update and six cyclotron interventions. The results provide a reference to establish the quality assurance (QA) frequency and tolerance for proton pencil beam scanning. A simple treatment plan was generated to produce an asymmetric 9-spot pattern distributed throughout a field of 16 × 18 cm for each of 18 proton energies (100.0-226.0 MeV). The delivered fluence distribution in air was measured using a phosphor screen based CCD camera at three planes perpendicular to the beam line axis (x-ray imaging isocenter and up/down stream 15.0 cm). The measured fluence distributions for each energy were analyzed using in-house programs which calculated the spot sizes and positional deviations of the Gaussian shaped spots. Compared to the spot characteristic data installed into the treatment planning system, the 16-month averaged deviations of the measured spot sizes at the isocenter plane were 2.30% and 1.38% in the IEC gantry x and y directions, respectively. The maximum deviation was 12.87% while the minimum deviation was 0.003%, both at the upstream plane. After the collinearity of the proton and x-ray imaging system isocenters was optimized, the positional deviations of the spots were all within 1.5 mm for all three planes. During the site configuration update, spot positions were found to deviate by 6 mm until the tuning parameters file was properly restored. For this beam delivery system, it is recommended to perform a spot size and position check at least monthly and any time after a database update or cyclotron intervention occurs. A spot size deviation tolerance of <15% can be easily met with this delivery system. Deviations of spot positions were <2 mm at any plane up/down stream 15 cm from the isocenter.

    Purpose Despite the existence of minimum age laws for juvenile justice jurisdiction in 18 US states, California has no explicit law that protects children (i.e. youth less than 12 years old) from being processed in the juvenile justice system. In the absence of a minimum age law, California lags behind other states and international practice and standards. The paper aims to discuss these issues. Design/methodology/approach In this policy brief, academics across the University of California campuses examine current evidence, theory, and policy related to the minimum age of juvenile justice jurisdiction. Findings Existing evidence suggests that children lack the cognitive maturity to comprehend or benefit from formal juvenile justice processing, and diverting children from the system altogether is likely to be more beneficial for the child and for public safety. Research limitations/implications Based on current evidence and theory, the authors argue that minimum age legislation that protects children from contact with the juvenile justice system and treats them as children in need of services and support, rather than as delinquents or criminals, is an important policy goal for California and for other national and international jurisdictions lacking a minimum age law. Originality/value California has no law specifying a minimum age for juvenile justice jurisdiction, meaning that young children of any age can be processed in the juvenile justice system. This policy brief provides a rationale for a minimum age law in California and other states and jurisdictions without one.

    Full Text Available Additional somatosensory contact of preterm human infants improves a variety of developmental assessment scores, but less is known about its lasting consequences. In rodents, maternal contact may influence the programming of juvenile social play behavior. Therefore, we used a paradigm where we can control the levels of somatosensory contact associated with maternal care. We find that additional somatosensory contact of offspring can have lasting consequences on juvenile social play behavior in a sex-dependent manner. Specifically, additional somatosensory stimuli reduced male social play behavior, but did not change female play behavior. We then examined if this additional infant contact altered some neurobiological substrates associated with play within the juvenile amygdala. Control males had lower levels of 5HT2a receptor mRNA levels contrasted to females; however, similar to its sex-dependent effect on juvenile social play, males that received additional somatosensory contact had higher serotonin 5HT2a receptor mRNA levels than control males. No difference was found in females. As serotonin signaling typically opposes juvenile play behavior, these data suggest that maternal touch can program lasting differences in juvenile social play and 5HT2a receptors mRNA levels within the juvenile amygdala.

    Measures of human mental development suggest that behavioral skills displayed during early life can predict an individual's subsequent cognitive performance. Support for this draws from longitudinal studies that reveal compelling within-subject correlations during childhood. If this idea applies across the life span, then correlations in performance should persist into adulthood. Here, we address this prediction in juvenile and adult gerbils by evaluating within-subject measures of auditory learning and perception. Animals were trained and tested as juveniles on either an amplitude modulation (AM) or a frequency modulation (FM) detection task. Measures of learning and perception obtained from juveniles were then compared to similar measures obtained when each subject was tested in adulthood on either the same task or the untrained task. For animals trained and tested on the AM detection task as juveniles and adults, there was no correlation between juvenile and adult learning metrics, or perceptual sensitivity. For animals trained and tested on FM detection as juveniles, we observed a significant relationship to their adult performance. Juveniles that performed the best on FM detection were the poorest at AM detection, and the best at FM detection, when tested as adults. Thus, across-age correlations for sensory and cognitive measures, obtained during development and in adulthood, depend heavily on the specific type of developmental experience and the outcome measure.

    Full Text Available Abstract Objective: This article reports on offense related characteristics and the psychosexual development in subgroups of juvenile sex offenders as measured by the Global Assessment Instrument for Juvenile Sex Offenders (GAIJSO. The predictive validity of these characteristics for persistent (sexual offensive behavior in subgroups of juvenile sex offenders was investigated. Methods: One hundred seventy four sex offenders (mean age 14.9 SD 1.4 referred by the police to the Dutch Child Protection Board were examined. Offense related characteristics were assessed by means of the GAIJSO and the BARO (a global assessment tool for juvenile delinquents, and criminal careers of the subjects were ascertained from official judicial records. Results: Serious need for comprehensive diagnostics were found on the domains sexual offense and psychosexual development in juvenile sex offenders, especially in the group of child molesters. These youngsters displayed more internalizing and (psychosexual developmental problems and their sexual offense was more alarming as compared to the other juvenile sex offender subgroups. Although one third of the juveniles had already committed one or more sex offenses prior to the index offense, at follow up (mean follow up period: 36 months SD 18 months almost no sexual recidivism was found (0.6% of the entire sample. However, a substantial proportion of the entire sample of juvenile sex offenders showed non-sexual (55.6% and violent recidivism (32.1%. Several predictors for a history of multiple sex offending and non-sexual recidivism were identified. Conclusion: This study revealed numerous problems in juvenile sex offenders. Assessment using the GAIJSO is helpful in order to identify indicators for extensive diagnostic assessment. In order to investigate the predictive validity for sexual reoffending a longer follow up period is necessary.

    2017-01-01

    While homicide perpetrated by juveniles is a relatively rare occurrence, between 2010 and 2014, approximately 7%–8% of all murders involved a juvenile offender. Unfortunately, few studies have prospectively examined the predictors of homicide offending, with none examining first-time murder among a sample of adjudicated male and female youth. The current study employed data on 5908 juvenile offenders (70% male, 45% Black) first arrested at the age of 12 or younger to prospectively examine predictors of an arrest for homicide/attempted homicide by the age of 18. Among these early-onset offenders, males, Black youth, those living in households with family members with a history of mental illness, those engaging in self-mutilation, and those with elevated levels of anger/aggression (all measured by age 13) were more likely to be arrested for homicide/attempted homicide by age 18. These findings add to the scant scientific literature on the predictors of homicide, and illustrate potential avenues for intervention. PMID:28212340

    In prospective longitudinal studies of juvenile offenders, the presence of multiple developmental pathways of antisocial behaviors has consistently been identified. An "antisocial" type of juvenile sex offender (JSO) has also been identified; however, whether antisocial JSOs follow different antisocial pathways has not been examined. In the current study, differences in antisocial pathways within JSOs and between JSOs and juvenile non-sex offenders (JNSOs) were examined. Data on Canadian male incarcerated adolescent offenders were used to identify whether behavioral antecedents differed within JSOs and between JSOs (n = 51) and JNSOs (n = 94). Using latent class analysis (LCA), three behavioral groups were identified. For both JSOs and JNSOs, there was a Low Antisocial, Overt, and Covert group. Overall, there were important within-group differences in the behavioral patterns of JSOs, but these differences resembled differences in the behavioral patterns of their JNSO counterpart. Risk factors including offense history, abuse history, and family history were more strongly associated with the Overt and Covert groups compared with the Low Antisocial group. Implications for JSO assessment practices were discussed.

  17. The crime prevention value of hot spots policing.

    Braga, Anthony A

    2006-08-01

    This paper reviews the available research evidence on the effectiveness of hot spots policing programs in reducing crime and disorder. The research identified five randomized controlled experiments and four non-equivalent control group quasi-experiments evaluating the effects of hot spots policing interventions on crime. Seven of nine selected evaluations reported noteworthy crime and disorder reductions. Meta-analyses of the randomized experiments revealed statistically significant mean effect sizes favoring hot spots policing interventions in reducing citizen calls for service in treatment places relative to control places. When immediate spatial displacement was measured, it was very limited and unintended crime prevention benefits were associated with the hot spots policing programs. The results of this review suggest that hot spots policing is an effective crime prevention strategy.

  18. Geographic variation and genetic structure in Spotted Owls

    We examined genetic variation, population structure, and definition of conservation units in Spotted Owls (Strix occidentalis). Spotted Owls are mostly non-migratory, long-lived, socially monogamous birds that have decreased population viability due to their occupation of highly-fragmented late successional forests in western North America. To investigate potential effects of habitat fragmentation on population structure, we used random amplified polymorphic DNA (RAPD) to examine genetic variation hierarchically among local breeding areas, subregional groups, regional groups, and subspecies via sampling of 21 breeding areas (276 individuals) among the three subspecies of Spotted Owls. Data from 11 variable bands suggest a significant relationship between geographic distance among local breeding groups and genetic distance (Mantel r = 0.53, P genetic drift. Merging nuclear data with recent mitochondrial data provides support for designation of an Evolutionary Significant Unit for Mexican Spotted Owls and two overlapping Management Units for Northern and California Spotted Owls.
