  2. Arsenic Specitation in Multiple Metal Environments: II. Micro-Spectroscopic Investigation of a CCA Contaminated Soil

    Energy Technology Data Exchange (ETDEWEB)

    Grafe,M.; Tappero, R.; Marcus, M.; Sparks, D.

    2008-01-01

    The speciation of arsenic (As) in a copper-chromated-arsenate (CCA) contaminated soil was investigated using micro-focused X-ray fluorescence (microXRF) and micro-focused X-ray absorption fine structure (microXAFS) spectroscopies to determine if and how the co-contaminating metal cations (Cu, Zn, Cr) influenced the speciation of As. 15 microXRF images were collected on 30-mum polished thin sections and powder-on-tape samples from which Pearson correlation coefficients (rho) between As and various metal species were determined based on the fluorescence intensity of each element in each image pixel. 29 microXAFS and two bulk-XAFS spectra were collected from depths of 0-20 cm (LM-A) and 20-40 cm (LM-B) to determine the chemical speciation of As in the soil by target analyses of principal components with circa 52 reference spectra and linear least-square combination fitting of individual experimental spectra with a refined reference phase list (32) of likely As species. Arsenic and metal cations (Cr, Mn, Fe, Cu, Zn) accumulated in distinct, isolated areas often not larger than 50 x 50 microm in which the Pearson correlation between the elements was strongly positive (rho>0.75). The correlation of As to Zn and Cr decreased from >0.9 to <0.8 and increased to Cu from approximately 0.6 to >0.8 with depth. Arsenic occurred predominantly in the +5 oxidation state. Abstract factor analysis and linear least square combination fit analysis suggested that As occurred as a continuum of fully and poorly-ordered copper-arsenate precipitates with additional components being characterized by surface adsorption complexes on goethite and gibbsite in the presence and absence of Zn. Precipitates other than copper-based ones, e.g., scorodite, adamite and ojuelaite were also identified. The significant co-localization and chemical speciation of As with Cu suggest that the speciation of As in a contaminated soils is not solely controlled by surface adsorption reactions, but significantly

    Full Text Available Welcome to the first Young Investigator Special Issue of the Journal of Sports Science and Medicine (JSSM. The JSSM family is proud to start this new service to the Sport Science community and to young researchers. The background in starting this issue was the observation that large amounts of high-quality research is conducted every year by students and young investigators, but often remains solely in local university libraries and never reaches the scientific community or databases. In addition, most international journals have a high threshold in accepting papers, and it is often hard to reach this level for junior scientists because of lack of experience, supervision or confidence. These are major reasons that delay or in some cases stop young researchers from publishing their valuable work. We all received help from senior colleagues in the beginning of our career. Now it is our turn to help youngsters. With this special issue, the JSSM is now serving young researchers as a channel for publishing their work. Our goal is to motivate young researchers to submit their work to JSSM, but we also aim to motivate supervisors and expert referees to be supportive and constructive towards these young scientists at the very beginning of their career. The Young Investigator Special Issue followed a normal peer-review process, except that there were no straight rejections in the first phase of review. We advised the reviewers of the Young Investigator Special Issue to proceed with constructive advice and remarks for all manuscripts. This offered a great opportunity for the Young Investigators to revise the manuscript, while at the same time contributing to the learning process. Thereafter, if the revisions were properly conducted according to the remarks from reviewers, the manuscripts were accepted for publication. We have received many manuscripts from young researchers with a lot of potential. There has been plenty of evidence of great talent

  7. Understanding the CCA Standard Through Decaf

    Energy Technology Data Exchange (ETDEWEB)

    Kumfert, G

    2003-04-17

    This document is a tutorial on the CCA Standard as realized through the Decaf implementation. Decaf does not equal the CCA standard much in the same way that Microsoft Visual C++ is not ANSI/ISO C++. This document was created because the CCA standard is evolving and still too fluid to nail down in a tutorial document. Because of its fluidity, and that it represents a hotbed of research and development, beginners can only start learning CCA by choosing one of the frameworks (warts and all). Decaf has just enough functionality to be a useful tool for beginners in the CCA to get started on. Though it lacks many features of the bigger CCA frameworks (CCAFE [3], XCAT [10], and SciRUN [8]) where the heavy-duty research is still going on, it is the first CCA framework that is underpinned by Babel, which provides its language interoperability features. This document can also serve the dual-purpose of providing a reasonable-sized example of building an application using Babel. The entire source for Decaf is included in the examples/subdirectory of the Babel code distribution. This manual assumes the reader is a programmer who has a conceptual understanding of the Babel Language Interoperability Tool. They should be proficient in two or more of the following languages: Fortran77, C, C++, Java, or Python. Furthermore, this manual assumes the reader is familiar with the SPMD{sup 2} programming model that pervades the scientific computing community. Knowledge of and experience with MPI programming is helpful, but not strictly required.

    Agricultural wastes are dumped in landfills or left on land in which they constitute nuisance. This study presents the results of investigation of strength characteristics of reinforced laterized concrete beams with cement partially replaced with corn cob (agricultural wastes) ash (CCA). Laterized concrete specimen of 25% laterite and 75% sharp sand were made by blending cement with corn cob ash at 0 to 40% in steps of 10%. A concrete mix ratio of 1:2:4 was used to cast 54 cubes of 150×150×150mm size and 54 beams of dimension 750×150×150mm. The results show that the consistency and setting time of cement increased as the percentage replacement of cement with CCA increased while the workability and density of concrete decreased as the percentage of CCA increased. There was a decrease in compressive strength when laterite was introduced to the concrete from 25.04 to 22.96N/mm2 after 28 days and a continual reduction in strength when CCA was further added from 10% to 40% at steps of 10%. Generally, the beam specimens exhibited majorly shear failure with visible diagonal cracks extending from support points to the load points. The corresponding central deflection in beams, due to two points loading, increased as the laterite was added to the concrete mix but reduced and almost approaching that of the control as 10% CCA was added. The deflection then increased as the CCA content further increased to 20%, 30% and 40% in the mix. It was also noted that the deflection of all percentage replacement including 40% CCA is less than the standard recommended maximum deflection of the beam. The optimal flexural strength occurred with 10% CCA content.

    Cholangiocarcinoma (CCA) is a serious problem in Thailand, particularly in the northeastern region. Active surveillance in rural communities with an appropriat low-cost screening tool is required to facilitate early detection. Therefore, this study aimed to investigate the population at risk of CCA in Bua Yai district, Nakhon Ratchasima province, Northeastern Thailand using the Korat-CCA verbal screening test (KCVST) during June to October 2015. Reliability of KCVST demonstrated a Cronbach alpha coefficient=0.75 Stepwise-multiple regression showed that alcohol consumption was important for CCA screened, followed by agriculture and pesticide use, under-cooked cyprinoid fish consumption, praziquantel use, naïve northeastern people, opisthorchiasis, family relatives with CCA, and cholangitis or cholecystitis or gallstones, respectively. Population at risk for CCA was classified to low risk (63.4%), moderate risk (33.7%), and high risk (1.32%) for CCA. When CCA was screened using ultrasonography, 4 of 32 high risk participants had an abnormal biliary tract with dilated bile ducts. This study indicates that KCVST is a potential useful too which decrease the cost of large scale CCA screening. PMID:27221919

    Preservatives such as chromated copper arsenate (CCA) are used to increase the resistance of wood to deterioration. The components of CCA are highly toxic, resulting in growing concern over the disposal of the waste generated. The aim of this study was to investigate the removal of Cu, Cr and As present in CCA-treated eucalyptus wood from utility poles removed from service in southern Brazil, in order to render them non-hazardous waste. The removal was carried out by acid leaching in bench-scale and applying optimal extractor concentration, total solid content, reactor volume, temperature and reaction time obtained by factorial experiments. The best working conditions were achieved using three extraction steps with 0.1 mol L(-1) H2SO4 at 75°C for 2h each (total solid content of 15%), and 3 additional 1h-long washing steps using water at ambient temperature. Under these conditions, removal of 97%, 85% and 98% were obtained for Cu, Cr and As, respectively, rendering the decontaminated wood non-hazardous waste. The wastewater produced by extraction showed acid pH, high organic loading as well as high concentrations of the elements, needing prior treatment to be discarded. However, rinsing water can be recycled in the extraction process without compromising its efficiency. The acid extraction is a promising alternative for CCA removal from eucalyptus wood waste in industrial scale. PMID:26856447

  14. Hfq stimulates the activity of the CCA-adding enzyme

    2007-10-01

    Full Text Available Abstract Background The bacterial Sm-like protein Hfq is known as an important regulator involved in many reactions of RNA metabolism. A prominent function of Hfq is the stimulation of RNA polyadenylation catalyzed by E. coli poly(A polymerase I (PAP. As a member of the nucleotidyltransferase superfamily, this enzyme shares a high sequence similarity with an other representative of this family, the tRNA nucleotidyltransferase that synthesizes the 3'-terminal sequence C-C-A to all tRNAs (CCA-adding enzyme. Therefore, it was assumed that Hfq might not only influence the poly(A polymerase in its specific activity, but also other, similar enzymes like the CCA-adding enzyme. Results Based on the close evolutionary relation of these two nucleotidyltransferases, it was tested whether Hfq is a specific modulator acting exclusively on PAP or whether it also influences the activity of the CCA-adding enzyme. The obtained data indicate that the reaction catalyzed by this enzyme is substantially accelerated in the presence of Hfq. Furthermore, Hfq binds specifically to tRNA transcripts, which seems to be the prerequisite for the observed effect on CCA-addition. Conclusion The increase of the CCA-addition in the presence of Hfq suggests that this protein acts as a stimulating factor not only for PAP, but also for the CCA-adding enzyme. In both cases, Hfq interacts with RNA substrates, while a direct binding to the corresponding enzymes was not demonstrated up to now (although experimental data indicate a possible interaction of PAP and Hfq. So far, the basic principle of these stimulatory effects is not clear yet. In case of the CCA-adding enzyme, however, the presented data indicate that the complex between Hfq and tRNA substrate might enhance the product release from the enzyme.

    Full Text Available Calcium and calmodulin-dependent protein kinase (CCaMK is a member of calcium/calmodulin-dependent protein kinase superfamily and is essential to microbe- plant symbiosis. To date, the distribution of CCaMK gene in plants has not yet been completely understood, and its function in plant disease resistance remains unclear. In this study, we systemically identified the CCaMK genes in genomes of 44 plant species in Phytozome and analyzed the function of tomato CCaMK (SlCCaMK in resistance to various pathogens. CCaMKs in 18 additional plant species were identified, yet the absence of CCaMK gene in green algae and cruciferous species was confirmed. Sequence analysis of full-length CCaMK proteins from 44 plant species demonstrated that plant CCaMKs are highly conserved across all domains. Most of the important regulatory amino acids are conserved throughout all sequences, with the only notable exception being observed in N-terminal autophosphorylation site corresponding to Ser 9 in the Medicago truncatula CCaMK. CCaMK gene structures are similar, mostly containing six introns with a phase profile of 200200 and the exception was only noticed at the first exons. Phylogenetic analysis demonstrated that CCaMK lineage is likely to have diverged early from a calcium-dependent protein kinase (CDPK gene in the ancestor of all nonvascular plant species. The SlCCaMK gene was widely and differently responsive to diverse pathogenic stimuli. Furthermore, knock-down of SlCCaMK reduced tomato resistance to Sclerotinia sclerotiorum and Pseudomonas syringae pv. tomato (Pst DC3000 and decreased H2O2 accumulation in response to Pst DC3000 inoculation. Our results reveal that SlCCaMK positively regulates disease resistance in tomato via promoting H2O2 accumulation. SlCCaMK is the first CCaMK gene proved to function in plant disease resistance.

  18. Rapid fixation of CCA wood preservative with electromagnetic energy

    International Nuclear Information System (INIS)

    Electromagnetic radiation, such as microwaves and radio-frequency currents, were shown to rapidly heat and fix chromated copper arsenate (CCA) chemicals in wood. This facilitates quick processing and shipment of treated products. For instance, microwaves were able to fix CCA preservative in southern pine in minutes rather than in hours or days. Verification by experiment showed that over 99 percent of the chromium was fixed in 30 minutes. In contrast, after storage for 6 days at 20 degrees C, about 12 percent was still water soluble and leached from the wood. Such accelerated fixation also occurred with copper and arsenic. Because of increasing environmental concerns, this approach is of value to the wood-treating industry

    This study reports a survey of occupational exposure to copper chrome arsenic (CCA) based wood preservatives during vacuum pressure timber impregnation. The survey involved biological monitoring based on analysis of chromium and arsenic in urine samples collected from UK workers. The aim of the study was to determine the extent of occupational exposure to arsenic and chromium in the UK timber treatment industry. The objectives were to collect and analyse urine samples from as many workers as possible, where CCA wood preservatives might be used, at 6 monthly intervals for 2 years. In addition, to investigate day-to-day variations in urinary excretion of chrome and arsenic by collecting and analysing three samples a week for 3 weeks in subsets of workers and controls (people not occupationally exposed). All urine samples were analysed for chromium and inorganic arsenic. To investigate any residual interference every sample was accompanied by a short questionnaire about recent consumption of seafood and smoking. The analytical methods for arsenic used a hydride generation technique to reduce interference from dietary sources of arsenic and also a technique that would measure total arsenic concentration in urine. The main findings show that workers exposed to CCA wood preservatives have concentrations of inorganic arsenic and chromium in urine that are significantly higher than those from non-occupationally exposed people but below biological monitoring guidance values that would indicate inhalation exposure at UK occupational exposure limits for chromium and arsenic. The effects of consumption of seafood on urinary arsenic were not significant using the hydride generation method for inorganic arsenic but were significant if 'total' arsenic was measured. The 'total' arsenic method could not distinguish CCA workers from controls and is clearly unsuitable for assessment of occupational exposure to arsenic. There was a significant increase in the urinary concentration of

  1. Leaching of CCA-treated wood: implications for waste disposal

    International Nuclear Information System (INIS)

    Leaching of arsenic, chromium, and copper from chromated copper arsenate (CCA)-treated wood poses possible environmental risk when disposed. Samples of un-weathered CCA-treated wood were tested using a variety of the US regulatory leaching procedures, including the toxicity characteristic leaching procedure (TCLP), synthetic precipitation leaching procedure (SPLP), extraction procedure toxicity method (EPTOX), waste extraction test (WET), multiple extraction procedure (MEP), and modifications of these procedures which utilized actual MSW landfill leachates, a construction and demolition (C and D) debris leachate, and a concrete enhanced leachate. Additional experiments were conducted to assess factors affecting leaching, such as particle size, pH, and leaching contact time. Results from the regulatory leaching tests provided similar results with the exception of the WET, which extracted greater quantities of metals. Experiments conducted using actual MSW leachate, C and D debris leachate, and concrete enhanced leachate provided results that were within the same order of magnitude as results obtained from TCLP, SPLP, and EPTOX. Eleven of 13 samples of CCA-treated dimensional lumber exceeded the US EPA's toxicity characteristic (TC) threshold for arsenic (5 mg/L). If un-weathered arsenic-treated wood were not otherwise excluded from the definition of hazardous waste, it frequently would require management as such. When extracted with simulated rainwater (SPLP), 9 of the 13 samples leached arsenic at concentrations above 5 mg/L. Metal leachability tended to increase with decreasing particle size and at pH extremes. All three metals leached above the drinking water standards thus possibly posing a potential risk to groundwater. Arsenic is a major concern from a disposal point of view with respect to ground water quality

    SunBlock `99 is a Web-based Public Understanding of Science and educational project which seeks to present the very latest solar research as seen through the eyes of young British scientists. These ``solar guides'' discuss not only their scientific interests, but also their extra-curricular activities and the reasons they chose scientific careers; in other words the human face of scientific research. The SunBlock '99 pages gather a range of solar images and movies from current solar space observatories and discuss the underlying physics and its relationship to the school curriculum. The instructional level is pitched at UK secondary school children (aged 13-16 years). It is intended that the material should not only provide a visually appealing introduction to the study of the Sun, but that it should help bridge the often wide gap between classroom science lessons and the research scientist `out in the field'. SunBlock '99 is managed by a team from the Rutherford Appleton Laboratory and the Universities of St Andrews and Cambridge, together with educational consultants. The production has, in part, been sponsored by PPARC and the Millennium Mathematics Project. Web site addresss: http://www.sunblock99.org.uk

    Research highlights: {yields} This paper describes a process for the metal removal from treated (CA-, ACQ- or MCQ-) wood wastes. {yields} This sulfuric acid leaching process is simple and economic. {yields} The remediated wood could be recycled in the industry. - Abstract: Chromated copper arsenate (CCA)-treated wood was widely used until 2004 for residential and industrial applications. Since 2004, CCA was replaced by alternative copper preservatives such as alkaline copper quaternary (ACQ), copper azole (CA) and micronized copper quaternary (MCQ), for residential applications due to health concerns. Treated wood waste disposal is becoming an issue. Previous studies identified a chemical process for decontaminating CCA-treated wood waste based on sulfuric acid leaching. The potential application of this process to wood treated with the copper-based preservatives (alkaline copper quaternary (ACQ), copper azole (CA) and micronized copper quaternary (MCQ)) is investigated here. Three consecutive leaching steps with 0.1 M sulfuric acid at 75 deg, C for 2 h were successful for all the types of treated wood and achieved more than 98% copper solubilisation. The different acidic leachates produced were successively treated by coagulation using ferric chloride and precipitation (pH = 7) using sodium hydroxide. Between 94 and 99% of copper in leachates could be recovered by electrodeposition after 90 min using 2 A electrical current. Thus, the process previously developed for CCA-treated wood waste decontamination could be efficiently applied for CA-, ACQ- or MCQ-treated wood.

    Analytical studies on the size effects of a simply-shaped beam fixed at both ends have successfully explained the sudden changes of effective Young's modulus as its diameter decreases below 100 nm. Yet they are invalid for complex nanostructures ubiquitously existing in nature. In accordance with a generalized Young-Laplace equation, one of the representative size effects is transferred to non-uniformly distributed pressure against an external surface due to the imbalance of inward and outward loads. Because the magnitude of pressure depends on the principal curvatures, iterative steps have to be adopted to gradually stabilize the structure in finite element analysis. Computational results are in good agreement with both experiment data and theoretical prediction. Furthermore, the investigation on strengthened and softened Young's modulus for two complex nanostructures demonstrates that the proposed computational method provides a general and effective approach to analyze the size effects for nanostructures in arbitrary shape.

    Because of the potentially high arsenic concentrations found in soils immediately adjacent to chromated copper arsenate (CCA)-treated wood structures and utility poles, CCA-contaminated soil ingestion may be a significant exposure route to arsenic for children. Therefore, a strong need exists to provide accurate data on oral relative bioavailability (RBA) of arsenic (in vivo or in vitro) in field-collected CCA-contaminated soils. The objectives of this study were (1) to assess arsenic bioaccessibility in contaminated soils collected near in-service CCA-treated utility poles, (2) to determine the influence of soil properties and arsenic fractionation on arsenic bioaccessibility, and (3) to estimate an average daily arsenic intake from incidental soil ingestion. Arsenic bioaccessibility (in vitro gastrointestinal (IVG) method) was determined on surface soil samples collected immediately adjacent to 12 CCA-treated utility poles after 18 months of service. Bioaccessible arsenic was also determined in 3 certified reference materials. Total arsenic concentrations in soils (RBA reported by Casteel et al. (2003) in soil near CCA-treated utility poles. Bioaccessible arsenic was positively correlated with total organic carbon content (r2 = 0.36, p < 0.05) and with water-soluble arsenic (2 = 0.51, p < 0.01), and was negatively correlated with clay content (r2 = 0.43, p < 0.05). Using conservative exposure parameters, the mean daily arsenic intake from incidental ingestion of contaminated soil near CCA-treated utility poles was 0.18 +/- 0.09 microg As kg(-1) d(-1). This arsenic intake appeared negligible compared to the daily intake of inorganic arsenic from water and food ingestion for children. PMID:16856753

  1. 2D-3D Face Recognition Method Based on a Modified CCA-PCA Algorithm

    2014-03-01

    Full Text Available This paper presents a proposed methodology for face recognition based on an information theory approach to coding and decoding face images. In this paper, we propose a 2D-3D face-matching method based on a principal component analysis (PCA algorithm using canonical correlation analysis (CCA to learn the mapping between a 2D face image and 3D face data. This method makes it possible to match a 2D face image with enrolled 3D face data. Our proposed fusion algorithm is based on the PCA method, which is applied to extract base features. PCA feature-level fusion requires the extraction of different features from the source data before features are merged together. Experimental results on the TEXAS face image database have shown that the classification and recognition results based on the modified CCA-PCA method are superior to those based on the CCA method. Testing the 2D-3D face match results gave a recognition rate for the CCA method of a quite poor 55% while the modified CCA method based on PCA-level fusion achieved a very good recognition score of 85%.

    Full Text Available In order to achieve more local facial feature, a kind of sub image face recognition method based on RS-Sp CCA feature information fusion is proposed in this paper. According to take samples for the local facial feature of sub image and use CCA to fuse the global facial feature and the local facial feature information after sampling, the global feature of image can be fully used to construct much more different kinds of component classifiers. Then, make experimental analysis on databases of 3 standard facial data sets. At last, the results show that sub image face recognition method based on RS-Sp CCA feature information fusion is better than the simple feature sampling method and feature fusion method. Besides, it can efficiently improve the face recognition rate.

    The rapid pace of motorisation in China has been well documented, as has the large road trauma burden the Chinese citizens are facing as a result. China's unique political system represents an important consideration in helping reduce road trauma, yet political factors have not been previously investigated in this context. Recently, emerging issues on the road involving the adult children of politically powerful families have become a serious social problem in China, and have drawn widespread media and public attention. This study took a novel approach to examining factors associated with risky attitudes and risky road use in China by investigating the economic and political background status of a sample of young Chinese drivers. An online survey was conducted in May 2015 with a sample size of 476 Chinese young drivers from across the country, aged between 18 and 28, including 305 males and 171 females. The results suggest that for participants who reported having a familial political background, more risky driving behaviours were reported among those participants who reported more impact on their life from that political background; while for participants without political background, higher personal income was associated with more risky driving behaviours. The findings are discussed in light of China's political management system and potential education opportunities for young drivers. PMID:27410174

    Animal enclosures are often constructed from wood treated with the pesticide chromated copper arsenate (CCA), which leaches arsenic (As) into adjacent soil during normal weathering. This study evaluated potential pathways of As exposure in 25 species of zoo animals living in CCA-wood enclosures. We analyzed As speciation in complete animal foods, dislodgeable As from CCA-wood, and As levels in enclosure soils, as well as As levels in biomarkers of 9 species of crocodilians (eggs), 4 species of birds (feathers), 1 primate species (hair), and 1 porcupine species (quills). Elevated soil As in samples from 17 enclosures was observed at 1.0-110mg/kg, and enclosures housing threatened and endangered species had As levels higher than USEPA's risk-based Eco-SSL for birds and mammals of 43 and 46mg/kg. Wipe samples of CCA-wood on which primates sit had dislodgeable As residues of 4.6-111μg/100cm(2), typical of unsealed CCA-wood. Inorganic As doses from animal foods were estimated at 0.22-7.8μg/kg bw/d. Some As levels in bird feathers and crocodilian eggs were higher than prior studies on wild species. However, hair from marmosets had 6.37mg/kg As, 30-fold greater than the reference value, possibly due to their inability to methylate inorganic As. Our data suggested that elevated As in soils and dislodgeable As from CCA-wood could be important sources of As exposure for zoo animals. PMID:26897404

    AIM: To study the role of focal adhesion kinase (FAK) and its association with Src in hepatocyte growth factor (HGF)-induced cell signaling in cholangiocarcinoma progression.METHODS: Previously isolated HuCCA-1 cells were re-characterized by immunofluorescent staining and reverse transcriptase-polymerase chain reaction assay for the expression of cytokeratin 19, HGF and c-Met mRNA. Cultured HuCCA-1 cells were treated with HGF and determined for cell proliferation and invasion effects by MTT and invasion assays. Western blotting, immunoprecipitation, and co-immunoprecipitation were also performed to study the phosphorylation and interaction of FAK and Src. A novel Src inhibitor (AZM555130) was applied in cultures to investigate the effects on FAK phosphorylation inhibition and on cell proliferation and invasion.RESULTS: HGF enhanced HuCCA-1 cell proliferation and invasion by mediating FAK and Src phosphorylations.FAK-Src interaction occurred in a time-dependent manner that Src was proved to be an upstream signaling molecule to FAK. The inhibitor to Src decreased FAK phosphorylation level in correlation with the reduction of cell proliferation and invasion.CONCLUSION: FAK plays a significant role in signaling pathway of HGF-responsive cell line derived from cholangiocarcinoma. Autophosphorylated Src, induced by HGF, mediates Src kinase activation, which subsequently phosphorylates its substrate, FAK, and signals to cell proliferation and invasion.

  11. Investigations of long-term effects of air pollutants on young forest trees

    International Nuclear Information System (INIS)

    In 1983 model ecosystems in open-top chambers were designed to investigate long-term effects of air pollutants (ozone and/or sulphur dioxide, simulated acidic rain) at realistic concentrations on mineral cycling, biochemistry and physiology of young forest trees. The chambers contain soil lysimeters and are protected against the intrusion of ambient rain. In the course of the exposure, alterations in mineral cycling and metabolic plant processes caused by sulphur dioxide and ozone could be observed. The combination of both pollutants often resulted in responses that were greater than the single effects. (orig.)

    Associations between parenting style and depressive symptomatology in a community sample of young adolescents (N = 2596) were investigated using self-report measures including the Parental Bonding Instrument and the Center for Epidemiologic Studies Depression Scale. Specifically, the 25-item 2-factor and 3-factor models by Parker et al. (1979), Kendler's (1996) 16-item 3-factor model, and Parker's (1983) quadrant model for the Parental Bonding Instrument were compared. Data analysis included analysis of variance and logistic regression. Reanalysis of Parker's original scale indicates that overprotection is composed of separate factors: intrusiveness (at the individual level) and restrictiveness (in the social context). All models reveal significant independent contributions from paternal care, maternal care, and maternal overprotection (2-factor) or intrusiveness (3-factor) to moderate and serious depressive symptomatology, controlling for sex and family living arrangement. Additive rather than multiplicative interactions between care and overprotection were found. Regardless of the level of parental care and affection, clinicians should note that maternal intrusiveness is strongly associated with adverse psychosocial health in young adolescents. PMID:15457107

The ages and masses of the majority of the candidate YSOs are estimated to be in the range ˜0.1-5 Myr and ˜0.3-6 M⊙, respectively. The 8-μm image of S311 displays an approximately spherical cavity around the ionizing source, which was possibly created by the expansion of the H II region. The spatial distribution of the candidate YSOs reveals that a significant number of them are distributed systematically along the 8-μm emission with a majority clustered around the eastern border of the H II region. Four clumps/compact H II regions are detected in the radio continuum observations at 1280 MHz, which may have been formed during the expansion of the H II region. The estimated dynamical age of the region, main-sequence lifetime of the ionizing source, the spatial distribution and ages of the candidate YSOs indicate triggered star formation in the complex.

    Concern about children's exposure to arsenic (As) from wood treated with chromated-copper-arsenate (CCA) led to its withdrawal from residential use in 2004. However, due to its effectiveness, millions of American homes still have CCA-wood decks on which children play. This study evaluated the effects of three deck-cleaning methods on formation of dislodgeable As and hexavalent chromium (CrVI) on CCA-wood surfaces and in leachate. Initial wipes from CCA-wood wetted with water showed 3-4 times more dislodgeable As than on dry wood. After cleaning with a bleach solution, 9.8-40.3μg/100cm(2) of CrVI was found on the wood surface, with up to 170μg/L CrVI in the leachate. Depending on the cleaning method, 699-2473mg of As would be released into the environment from cleaning a 18.6-m(2)-deck. Estimated As doses in children aged 1-6 after 1h of playing on a wet CCA-wood deck were 0.25-0.41μg/kg. This is the first study to identify increased dislodgeable As on wet CCA-wood and to evaluate dislodgeable CrVI after bleach application. Our data suggest that As and CrVI in 25-year old CCA-wood still show exposure risks for children and potential for soil contamination. PMID:26004992

    Function AutoBiplot.CCA was built in R language. Given two multivariate data sets, this function carries out a conventional canonical correlation analysis, followed by the automatic production of predictive biplots based on the accuracy of readings as assessed by a mean standard predictive error and a user defined tolerance value. As the user's intervention is mainly restricted to the choice of the magnitude of the t.axis value, common misinterpretations, overestimations and adjustments between outputs and personal beliefs are avoided.

  8. Anonymous Multi-Receiver Identity-Based Authenticated Encryption with CCA Security

    Directory of Open Access Journals (Sweden)

    Chun-I Fan

    2015-10-01

    Full Text Available In a multi-receiver encryption system, a sender chooses a set of authorized receivers and sends them a message securely and efficiently, as the message is well encrypted and only one ciphertext corresponding to the message is generated no matter how many receivers the sender has chosen. It can be applied to video conferencing systems, pay-per-view channels, remote education, and so forth. Due to privacy considerations, an authorized receiver may not expect that his identity is revealed. In 2010, anonymous multi-receiver identity-based (ID-based encryption was first discussed, and furthermore, many works on the topic have been presented so far. Unfortunately, we find that all of those schemes fail to prove the chosen ciphertext attacks (CCA security in either confidentiality or anonymity. In this manuscript, we propose the first anonymous multi-receiver ID-based authenticated encryption scheme with CCA security in both confidentiality and anonymity. In the proposed scheme, the identity of the sender of a ciphertext can be authenticated by the receivers after a successful decryption. In addition, the proposed scheme also is the first CCA-secure one against insider attacks. Moreover, only one pairing computation is required in decryption.

    2013-03-01

    Background and aims The primary objective of the present research is to investigate the drivers of technological addiction in college students - heavy users of Information and Communication Technology (ICT). The study places cell phone and instant messaging addiction in the broader context of consumption pathologies, investigating the influence of materialism and impulsiveness on these two technologies. Clearly, cell phones serve more than just a utilitarian purpose. Cell phones are used in public and play a vital role in the lives of young adults. The accessibility of new technologies, like cell phones, which have the advantages of portability and an ever increasing array of functions, makes their over-use increasingly likely. Methods College undergraduates (N = 191) from two U.S. universities completed a paper and pencil survey instrument during class. The questionnaire took approximately 15-20 minutes to complete and contained scales that measured materialism, impulsiveness, and mobile phone and instant messaging addiction. Results Factor analysis supported the discriminant validity of Ehrenberg, Juckes, White and Walsh's (2008) Mobile Phone and Instant Messaging Addictive Tendencies Scale. The path model indicates that both materialism and impulsiveness impact the two addictive tendencies, and that materialism's direct impact on these addictions has a noticeably larger effect on cell phone use than instant messaging. Conclusions The present study finds that materialism and impulsiveness drive both a dependence on cell phones and instant messaging. As Griffiths (2012) rightly warns, however, researchers must be aware that one's addiction may not simply be to the cell phone, but to a particular activity or function of the cell phone. The emergence of multi-function smart phones requires that research must dig beneath the technology being used to the activities that draw the user to the particular technology. PMID:26165772

    In this paper, we describe the architecture and performance of the GraCCA system, a Graphic-Card Cluster for Astrophysics simulations. It consists of 16 nodes, with each node equipped with 2 modern graphic cards, the NVIDIA GeForce 8800 GTX. This computing cluster provides a theoretical performance of 16.2 TFLOPS. To demonstrate its performance in astrophysics computation, we have implemented a parallel direct N-body simulation program with shared time-step algorithm in this system. Our system achieves a measured performance of 7.1 TFLOPS and a parallel efficiency of 90% for simulating a globular cluster of 1024K particles. In comparing with the GRAPE-6A cluster at RIT (Rochester Institute of Technology), the GraCCA system achieves a more than twice higher measured speed and an even higher performance-per-dollar ratio. Moreover, our system can handle up to 320M particles and can serve as a general-purpose computing cluster for a wide range of astrophysics problems.

  15. A story with a good ending: tRNA 3'-end maturation by CCA-adding enzymes.

    Science.gov (United States)

    Xiong, Yong; Steitz, Thomas A

    2006-02-01

    CCA-adding enzymes (tRNA nucleotidyltransferases) are responsible for the maturation or repair of the functional 3' end of tRNAs. These enzymes are remarkable because they polymerize the essential nucleotides CCA onto the 3' terminus of tRNA precursors without using a nucleic acid template. Recent crystal structures, plus three decades of enzymology, have revealed the elegant mechanisms by which CCA-adding enzymes achieve their substrate specificity in a nucleic acid template independent fashion. The class I CCA-adding enzyme employs both an arginine sidechain and backbone phosphates of the bound tRNA to recognize incoming nucleotides. It switches from C to A addition through changes in the size and shape of the nucleotide-binding pocket, which is progressively altered by the elongating 3' terminus of the tRNA. By contrast, the class II CCA-adding enzyme uses only amino acid sidechains, which form a protein template for incoming nucleotide selection. PMID:16364630

T. Blake, aiming their use as treated wood. The study was conducted with material from commercial plantations, with 63 months of age. For the wood characterization, the relationship sapwood-heartwood, the basic density and the size of fibers and vessels were evaluated. For the evaluation of treated wood, the penetration and retention of copper chrome arsenate (CCA type C were determined. Four trees per rotation and genetic material were used, which subsequently were split into three logs, in a total of 12 logs for each treatment. The preservative treatment was performed using the full cell process in autoclave using CCA solution with 2% concentration of active ingredients. The treatment process used was effective under the conditions required by the NBR 9480, with retention values ​​higher than the minimum required by the standard, which is 6.5 kg/m3 of CCA per treated wood, and in addition, provided deep penetration and regular condom in sapwood of all timber treated. There are no restrictions on the use of wood from the first and second rotation for preservative treatment, based on the properties evaluated. There was no correlation between the type C CCA retention and wood properties evaluated.

    The proper end-of-life management of chromated copper arsenate (CCA)-treated wood, which contains arsenic, copper, and chromium, is a concern to the solid waste management community. Landfills are often the final repository of this waste stream, and the impacts of CCA preservative metals on leachate quality are not well understood. Monofills are a type of landfill designed and operated to dispose a single waste type, such as ash, tires, mining waste, or wood. The feasibility of managing CCA-treated wood in monofills was examined using a simulated landfill (a leaching lysimeter) that contained a mix of new and weathered CCA-treated wood. The liquid to solid ratio (LS) reached in the experiment was 0.63:1. Arsenic, chromium, and copper leached from the lysimeter at average concentrations of 42 mg/L for arsenic, 9.4 mg/L for chromium, and 2.4 mg/L for copper. Complementary batch leaching studies using deionized water were performed on similar CCA-treated wood samples at LS of 5:1 and 10:1. When results from the lysimeter were compared to the batch test results, copper and chromium leachability appeared to be reduced in the lysimeter disposal environment. Of the three metals, arsenic leached to the greatest extent and was found to have the best correlation between the batch and the lysimeter experiments. PMID:16406290

Using a distributed coordination function (DCF, the CSMA/CA protocol reduces collisions and improves the overall throughput. To mitigate fairness issues arising with CSMA/CA, we develop a modified version that we term CSMA with copying collision avoidance (CSMA/CCA. A station in CSMA/CCA contends for the shared wireless medium by employing a binary exponential backoff similar to CSMA/CA. Different from CSMA/CA, CSMA/CCA copies the contention window (CW size piggybacked in the MAC header of an overheard data frame within its basic service set (BSS and updates its backoff counter according to the new CW size. Simulations carried out in several WLAN configurations illustrate that CSMA/CCA improves fairness relative to CSMA/CA and offers considerable advantages for deployment in the 802.11-standard-based WLANs.

    Objective The study was to investigate the relationship among angiotensin 1-converting enzyme(ACE), plasminogen activator inhibitor-1 (PAI-1)gene polymorphisms and the common carotid artery (CCA-IMT), and the predicting effects of them on CCA-IMT in newly diagnosed type 2 diabetes (T2DM). Methods The polymorphisms of ACE (I/D) gene and PAI-I (4G/5G) gene were deter-mined by polymemse chain reaction-restriction fragment length polymorphism (PCR-RFLP) and allele-specific polymerase chain reaction (AS-PCR) method in 308 cases with T2DM. CCA-IMT was compared among the groups with different genotypes of ACE and PAI-1. The in-dependent or synergistic effects of the ACE I/D and PAI-1 40/5G polymorphisms on CCA-IMT in 308 patients with T2DM were analyzed with multivariate linear regression. Then the 156 newly diagnosed type 2 diabetics (durations< I year) without AS received the maltifactorial targeted intervention, including taking aspirin and controlling blood glucose, blood pressure, blood lipid and body weight. The differences of metabolic control, ACE (I/D) and PAId (40/5G) gene polymorphisms were analyzed. Logistic regression analysis was used to analyze the eorrelation among the CCA-IMT, ACE (I/D) and PAI-1 (4G/5G) polymorphisms. Results Patients with ACE DD genotypes had higher CCA-IMT than those with ACE-Ⅱ or ACE ID genotypes. Patients with both ACE DD and PAI-1 404G genotypes had a higher CCA-IMT than those with any other pairs of genotypes. Multivariate linear regression analysis showed that ACE DD and PAI-1 4G4G gene polymorphisms had synergistic effect on the CCA-IMT in T2DM patients. After 2 years multifactorial intervention, the frequencies of PAI-1 4G alleles and 404G genotypas were lower than those in the CCA-IMT non-inereasing group. Conclusions These findings indicate that the ACE-DD geno-type and its synergistic effects with the PAI-1 4G/4G genotype are independent risk factors for the CCA-IMT in T2DM patients. Under multi-factorial intervention for 2

    Removal of Cu and Cr from chromated copper arsenate (CCA)-treated wood waste under batch electrodialytic conditions was studied. The effect of different types of extracting solutions, such as deionised water or aqueous solutions of NaCl, formic acid, oxalic acid, and EDTA, on the magnitude and...... direction of the fluxes of Cu- and Cr-containing species in the electrodialytic cell was investigated. Oxalic acid was found to have the best performance if simultaneous removal of the two elements is required (removal efficiencies of 80.5% for Cu and 87.4% for Cr, respectively). A mixture of oxalic acid...... and formic acid also led to similar removal efficiencies. In these experiments, the target elements were accumulated in both the anode and cathode compartments of the electrodialytic cell due to the formation of negatively charged complexes with the organic acids used besides the free cationic forms...

    Full Text Available Growth in executive functioning (EF skills play a role children's academic success, and the transition to elementary school is an important time for the development of these abilities. Despite this, evidence concerning the development of the ERP components linked to EF, including the error-related negativity (ERN and the error positivity (Pe, over this period is inconclusive. Data were recorded in a school setting from 3- to 7-year-old children (N = 96, mean age = 5 years 11 months as they performed a Go/No-Go task. Results revealed the presence of the ERN and Pe on error relative to correct trials at all age levels. Older children showed increased response inhibition as evidenced by faster, more accurate responses. Although developmental changes in the ERN were not identified, the Pe increased with age. In addition, girls made fewer mistakes and showed elevated Pe amplitudes relative to boys. Based on a representative school-based sample, findings indicate that the ERN is present in children as young as 3, and that development can be seen in the Pe between ages 3 and 7. Results varied as a function of gender, providing insight into the range of factors associated with developmental changes in the complex relations between behavioral and electrophysiological measures of error processing.

    Full Text Available Food services are basic services of the tourism offer. Unlike the other elements of the tourism product sold to a visitor, the offer of food units target to a high extent the residents. The habit to satisfy the need of food & beverage in specialized units, concept known under the name of “dining-out”, records in Romania a lower spread in comparison with developed states. This situation is determined by the low level of incomes, the lack of the lunch break with a duration of at least one hour in the working program of many companies which could favor serving the meal in a food unit, etc, but also the concern of the restaurants to satisfy the demand for events (weddings, baptisms, etc or satisfying the needs of socialization and amusement of population during evenings. The article aims to highlight the opinions and attitudes of young consumers from Romania regarding the food service consumption, the elements which determine the decision to eat in a restaurant and the issues that might favor this action.

    Full Text Available This project examined the lifestyle, health habits and risk factors of young adults at Qatar University. It explored the clustering and differences in dietary habits, body mass index (BMI and physical activity (PA amongst male and female students, both Qatari and non-Qatari. Seven hundred thirty two students aged 18–25 years completed a self-reported questionnaire and an objective measure of BMI. Males and females had a high prevalence of being overweight and obesity and low levels of PA, according to well-established international standards. Three clusters were identified based on the students’ lifestyle and dietary habits. Cluster 1 (high risk factors included those who engaged the least in healthy dietary practices and consumed the most unhealthy foods, participated in less PA and had the highest BMI. Cluster 2 (moderate risk factors included those with considerably more habits falling into the moderate category, engagement in the most PA, the least TV and computer viewing time and had the lowest BMI. Cluster 3 (low risk factors included those who engaged the most with the four healthy dietary practices, the least with the four unhealthy dietary practices and participated in moderate PA per week. This project provides valuable data that could be used by policy makers to address issues concerning student’s health.

    Violence in the physical (offline) world is a well-documented health and social issue among young people worldwide. In Southeast Asia, online harassment (defined as intentional behaviours to harm others through the Internet or through mobile devices) is less well documented. In this paper, we describe and critically discuss the mixed-methods data collection approach we used to build a contextualised understanding of offline violence and online harassment among 15- to 24-year-old students and out-of-school youth in Central Thailand. We mapped linkages between offline violence and online harassment, and with their possible correlates including gender, sexuality, and mobile media or Internet use. Data collection methods included in-depth interviews, focus group discussions and a custom-built, self-administered computerised survey. Using mixed methods enabled us to collect holistic qualitative/quantitative data from both students and out-of-school youth. In our discussion, we focus on gender, sexuality, class and ethnicity issues in recruiting out-of-school youth; definition and measurement issues; technical issues in using a computerised survey; ethical issues surrounding data collection from minors as well as privacy and confidentiality concerns in collecting data in both in-school and out-of-school settings; and the general implications of using mixed methods.

    2001-01-01

    The relations between lake surface sediment diatoms and water environmental variables were revealed effectively by use of a new multivariate canonical correspondence analysis (CCA) based on 45 lakes in the Tibetan Plateau. Water depth, conductivity, Cl-, Mg2+, K+ and pH, identified from 12 contemporary water environmental variables, can significantly and independently explain the diatom distributions (p<0.05). The first two axes (λ1=0.34, λ2=0.27) capture 16.1% of the variance in the species data, and account for 57.4% of the variance in diatom-environment relationship. The deletion of redundant environmental variables and unusual samples do not influence the explanation to diatom data. The final CCA result indicates that the water depth and the salinity are the two important environmental gradients and influence the diatom distribution in the plateau lakes. The water depth correlates with axis 1, while conductivity, Cl-, Mg2+ and K+, indicating the direction of salinity changes, corr

  2. Evaluation of the wood CCA preservative treatment process of Eucalyptus (Eucaliptus ssp) by X-ray fluorescence technique

    International Nuclear Information System (INIS)

    Brazil produces around 1,2 mi m3 of treated wood to meet the annual demand of railway, electric, rural and construction sectors. The treated woods used for poles, sleepers, fence posts and plywoods should be according to Brazilian norms requirements. The most used wood species are eucalyptus (Eucaliptus ssp)and pine (Pinus ssp). The most wood preservative products used in Brazil are CCA (Chromated Copper Arsenate) and CCB (Copper Chromium and Boron Salt). The analytical methods, such as Flame Atomic Absorption Spectrometry (FAAS) and Plasma Inductively Coupled Optical Emission Spectrometry (ICPOES) have been used for the evaluation of those treatment processes. In this work, the sapwood sample was obtained from eucalyptus trees (Eucaliptus ssp) obtained from Minas Gerais State, Brazil, cut plantation areas. Sawdust sapwood sample was grounded and submitted to different additions of CCA solutions (0.2, 0.7, 1.3, 2.3, 3.6, 6.3, 11.7and17.9 kg m-3). Power and pressed pellets sapwood samples, analyzed by EDXRFS, showed a good linear relation (r2>0.99) between the characteristic intensity fluorescent lines (CuΚα, CrΚαand AsΚΒ) and their concentration, also, showed adequate sensitivity (LQ -1) for Cu, Cr and As determination in treated woods. Cu, Cr and As were determined in powdered sawdust samples by FAA spectrometry, using the AWPA A11-93 standard method; the relation between the CCA retention and their concentration showed a lower linear relation than EDXRFS; the FAAS spreading result could be attributed to laboratorial CCA addition process.

    2010-04-01

    This study looks into the potential risks of arsenic, chromium, and copper leaching from disposed hardwoods treated with chromated copper arsenate (CCA) in a tropical climate. The Toxicity Characteristic Leaching Procedure (TCLP) and the Waste Extraction Test (WET) were employed to examine new CCA-treated Burseraceae and Keruing woods, weathered CCA-treated teak wood, and ash from new CCA-treated Burseraceae wood. In addition, a total of six lysimeters, measuring 2 m high and 203 mm in diameter were prepared to compare the leachate generated from the wood monofills, construction and demolition (C&D) debris landfills and municipal solid waste (MSW) landfills, containing CCA-treated Burseraceae wood. The TCLP and WET results showed that the CCA-treated Burseraceae wood leached higher metal concentrations (i.e. 9.19-17.70 mg/L, 1.14-5.89 mg/L and 4.83-23.89 mg/L for arsenic, chromium, and copper, respectively) than the CCA-treated Keruing wood (i.e. 1.74-11.34 mg/L, 0.26-3.57 mg/L and 0.82-13.64 mg/L for arsenic, chromium and copper, respectively). Ash from the CCA-treated Burseraceae wood leached significantly higher metal concentrations (i.e. 108.5-116.9 mg/L, 1522-3862 mg/L and 84.03-114.4 mg/L for arsenic, chromium and copper, respectively), making this type of ash of high concern. The lysimeter study results showed that the MSW lysimeter exhibited higher reducing conditions, more biological activities and more dissolved ions in their leachates than the wood monofill and C&D debris lysimeters. All leachates generated from the lysimeters containing the CCA-treated Burseraceae wood contained significantly higher concentrations of arsenic in comparison to those of the untreated wood: in the range of 0.53-15.7 mg/L. It can be concluded that the disposal of CCA-treated Burseraceae wood in an unlined C&D landfill or a MSW landfill has the potential to contaminate groundwater. PMID:20450112

  11. Exergy analysis of the Chartherm process for energy valorization and material recuperation of chromated copper arsenate (CCA) treated wood waste

    International Nuclear Information System (INIS)

    The Chartherm process (Thermya, Bordeaux, France) is a thermochemical conversion process to treat chromated copper arsenate (CCA) impregnated wood waste. The process aims at maximum energy valorization and material recuperation by combining the principles of low-temperature slow pyrolysis and distillation in a smart way. The main objective of the exergy analysis presented in this paper is to find the critical points in the Chartherm process where it is necessary to apply some measures in order to reduce exergy consumption and to make energy use more economic and efficient. It is found that the process efficiency can be increased with 2.3-4.2% by using the heat lost by the reactor, implementing a combined heat and power (CHP) system, or recuperating the waste heat from the exhaust gases to preheat the product gas. Furthermore, a comparison between the exergetic performances of a 'chartherisation' reactor and an idealized gasification reactor shows that both reactors destroy about the same amount of exergy (i.e. 3500 kW kgwood-1) during thermochemical conversion of CCA-treated wood. However, the Chartherm process possesses additional capabilities with respect to arsenic and tar treatment, as well as the extra benefit of recuperating materials.

  12. Effect of post treatment temperature and humidity conditions on fixation performance of CCA-C treated red pine and southern pine

    Institute of Scientific and Technical Information of China (English)

    1999-01-01

    Rates of fixation in chromated copper arsenate (CCA-C) treated red pine (Pinus resinosa Ait.) and southern pine (Pinus spp) sapwood specimens using retention of 1.5, 2.0, 6.4 kg·m-3 are compared at temperature (T) ranging from 70 ℃ to 50 ℃ and 5 different relative humidity (RH) conditions. The samples were investigated using the expressate method to follow chromium fixation. Red pine fixes faster than southern pine under all 11 post treatment schedules. The fixation rates for both species are not significantly different while the blocks were fixed under 6 fixation/drying schedules that differed only in the order of T/RH conditions applied. The rate of fixation of all samples in any fixation stage were reduced when the blocks were fixed under lower humidity conditions in spite of no change in chamber temperature. Some of this influence can be attributed to the effect of humidity on heat transfer into the wood and cooling of the wood surface.

  13. CHROMATED COPPER ARSENATE (CCA TREATED WOOD: DESTINATION OPTIONS FOR WASTES GENERATED AND PERSPECTIVES IN THE DEVELOPMENT OF METHODOLOGIES FOR TOXIC ELEMENTS REMOVAL

    Directory of Open Access Journals (Sweden)

    PIRES, Marçal

    2015-01-01

    Full Text Available The wood has been used for various functions, one of them is the manufacture of poles for electrification and telephony. However, this material has a big propensity to deteriorate. To increase its durability, some alternatives are employed, one of them is the incorporation of toxic substances (preservatives to protect the wood from agents such as fungi, bacteria and xylophagous insects that cause its decay. Currently, the preservative chromated copper arsenate (CCA is the most widely used for this purpose. However, when the CCA treated wood poles reach the end of their useful life, they become hazardous waste due to the presence of chromium and arsenic. In this work are presented the main methodologies for treatment, destination options and adequate disposal of these wastes, as well as different methods for toxic elements removal from the CCA-treated wood

  14. Zumba crater, Daedalia Planum, Mars: Geologic investigation of a young, rayed impact crater and its secondary field

    Chuang, Frank C.; Crown, David A.; Tornabene, Livio L.

    2016-05-01

    Zumba is a ∼2.9 km diameter rayed crater on Mars located on extensive lava plains in Daedalia Planum to the southwest of Arsia Mons. It is a well-preserved young crater with large ejecta rays that extend for hundreds of kilometers from the impact site. The rays are thermally distinct from the background lava flows in THEMIS daytime and nighttime thermal infrared data, a unique characteristic among martian rayed craters. Concentrated within the rays are solitary or dense clusters of secondary craters with associated diffuse dark-toned deposits along with fewer secondary craters lacking dark-toned deposits. Using CTX images, we have mapped secondary craters with dark-toned deposits, collectively termed "secondary fields", to investigate their distribution as a function of distance from the impact site. The mapped secondary field was then used to investigate various aspects of the crater-forming event such as the surface angle and direction of the projectile, the effect of secondary craters on surface age estimates, and the number of secondary craters produced by the impact event. From our mapping, a total of 13,064 secondary fields were documented out to a 200 km radial distance beyond a 15 km-wide non-secondary zone around Zumba crater. Results show that the highest areal coverage of secondary fields occurs within 100 km of Zumba and within its rays, decreasing radially with distance to a background scattering of small secondary fields that are population). The strong east-west asymmetry of crater rays and low areal coverage of fields to the south of Zumba correlate well with studies of Zumba impact melt deposits, indicating a moderately oblique impact projectile coming from the south. Using primary craters in a ∼101 km2 sample region and all craters (primaries and secondaries) from 43 select secondary fields in two map sectors in the study area, we obtain ages of ∼580 ± 100 Ma and ∼650 ± 70 Ma, respectively, for the lava flows into which Zumba impacted

    CCA 1 gene plays an important role in circadian clock sensitivity in rice (Oryza sativa L. ) and Arabidopsis thaliana. In this study, CCAl gene in barley was cloned by RT-PCR using homological primers based on the highly conserved region of the multiple alignments of the rice and Arabidopsis. The similarities of this sequence were up to 72% and 69%, respectively, to corresponding mRNA sequences of rice and maize in BLASTx of GenBank database. Using ORF Finder software, a 2157 bp open reading frame was found to code 718 amino acids. Using Compute pI/Mw tool, the amino acid sequence was analyzed, and it revealed that the molecular weight of this protein was about 77 769. 4 Da, and isoelectric point was about 6. 55. We established fluorescence quantitative RT-PCR system with barley inbred lines HUADAMAI 1 and HUADAMAI 2, and studied the expression of CCAl in leaf under 16h/8h (light/ dark) conditions. Expression analysis showed that the gene expression peaked at dawn (ZTO) then gradually declined from ZTO to ZT15, bottomed at ZT15, then increased and returned to the initial level at ZT24.

  18. Mode of Action of RNase BN/RNase Z on tRNA Precursors: RNase BN DOES NOT REMOVE THE CCA SEQUENCE FROM tRNA*

    OpenAIRE

    Dutta, Tanmay; Deutscher, Murray P.

    2010-01-01

    RNase BN, the Escherichia coli homolog of RNase Z, was previously shown to act as both a distributive exoribonuclease and an endoribonuclease on model RNA substrates and to be inhibited by the presence of a 3′-terminal CCA sequence. Here, we examined the mode of action of RNase BN on bacteriophage and bacterial tRNA precursors, particularly in light of a recent report suggesting that RNase BN removes CCA sequences (Takaku, H., and Nashimoto, M. (2008) Genes Cells 13, 1087–1097). We show that ...

    The link between child sexual abuse and adult intimate partner violence surfaces throughout prior research. Nonetheless, methodologies investigating this cycle of violence predominantly involve descriptive, correlational, or traditional regression-based analyses that preclude more definitive statements about the empirical relationship between child sexual abuse and adult partner violence. In recognition of these limitations, the current study presents a quasi-experimental investigation into the relationship between sexual abuse in childhood and physical partner violence victimization and/or perpetration in young adulthood. Propensity score matching analysis of a national data set sampling over 4,000 young adults suggests that experiencing child sexual abuse influences adult intimate partner violence victimization and perpetration. Study implications and directions for future research are discussed. PMID:26340073

    Sanjay G Lala

    Full Text Available Contact tracing, to identify source cases with untreated tuberculosis (TB, is rarely performed in high disease burden settings when the index case is a young child with TB. As TB is strongly associated with HIV infection in these settings, we used source case investigation to determine the prevalence of undiagnosed TB and HIV in the caregivers and household contacts of hospitalised young children diagnosed with TB in South Africa.Caregivers and household contacts of 576 young children (age ≤7 years with TB diagnosed between May 2010 and August 2012 were screened for TB and HIV. The primary outcome was the detection of laboratory-confirmed, newly-diagnosed TB disease and/or HIV-infection in close contacts.Of 576 caregivers, 301 (52·3% self-reported HIV-positivity. Newly-diagnosed HIV infection was detected in 63 (22·9% of the remaining 275 caregivers who self-reported an unknown or negative HIV status. Screening identified 133 (23·1% caregivers eligible for immediate anti-retroviral therapy (ART. Newly-diagnosed TB disease was detected in 23 (4·0% caregivers. In non-caregiver household contacts (n = 1341, the prevalence of newly-diagnosed HIV infection and TB disease was 10·0% and 3·2% respectively. On average, screening contacts of every nine children with TB resulted in the identification of one case of newly-diagnosed TB disease, three cases of newly diagnosed HIV-infection, and three HIV-infected persons eligible for ART.In high burden countries, source case investigation yields high rates of previously undiagnosed HIV and TB infection in the close contacts of hospitalised young children diagnosed with TB. Furthermore, integrated screening identifies many individuals who are eligible for immediate ART. Similar studies, with costing analyses, should be undertaken in other high burden settings-integrated source case investigation for TB and HIV should be routinely undertaken if our findings are confirmed.

    2012-04-01

    Opioid dependence is an increasingly prevalent problem throughout the world, particularly for young adults (e.g., ages 17-25 years). Opioid dependence is associated with a wealth of negative consequences and is often a chronic, relapsing condition. Research on factors that may contribute to the etiology of opioid dependence could result in improved treatment outcomes. Using preexisting patient records, the current study examined early maladaptive schemas among young adult opioid-dependent residential treatment patients (N = 169), as it is theorized that early maladaptive schemas may underlie or maintain substance use. Results showed that all 18 early maladaptive schemas were endorsed at various levels among male and female patients, with insufficient self-control being the most prevalent schema. In addition, females scored significantly higher than males on 11 of the 18 schemas. Findings from the current study are discussed in terms of future research and implications for the treatment of opioid dependence. PMID:22014405

  6. The functional interplay between protein kinase CK2 and CCA1 transcriptional activity is essential for clock temperature compensation in Arabidopsis.

    2010-11-01

    Full Text Available Circadian rhythms are daily biological oscillations driven by an endogenous mechanism known as circadian clock. The protein kinase CK2 is one of the few clock components that is evolutionary conserved among different taxonomic groups. CK2 regulates the stability and nuclear localization of essential clock proteins in mammals, fungi, and insects. Two CK2 regulatory subunits, CKB3 and CKB4, have been also linked with the Arabidopsis thaliana circadian system. However, the biological relevance and the precise mechanisms of CK2 function within the plant clockwork are not known. By using ChIP and Double-ChIP experiments together with in vivo luminescence assays at different temperatures, we were able to identify a temperature-dependent function for CK2 modulating circadian period length. Our study uncovers a previously unpredicted mechanism for CK2 antagonizing the key clock regulator CIRCADIAN CLOCK-ASSOCIATED 1 (CCA1. CK2 activity does not alter protein accumulation or subcellular localization but interferes with CCA1 binding affinity to the promoters of the oscillator genes. High temperatures enhance the CCA1 binding activity, which is precisely counterbalanced by the CK2 opposing function. Altering this balance by over-expression, mutation, or pharmacological inhibition affects the temperature compensation profile, providing a mechanism by which plants regulate circadian period at changing temperatures. Therefore, our study establishes a new model demonstrating that two opposing and temperature-dependent activities (CCA1-CK2 are essential for clock temperature compensation in Arabidopsis.

    2008-09-01

    Full Text Available Abstract Background The Mood and Anxiety Symptom Questionnaire (MASQ was designed to specifically measure the Tripartite model of affect and is proposed to offer a delineation between the core components of anxiety and depression. Factor analytic data from adult clinical samples has shown mixed results; however no studies employing confirmatory factor analysis (CFA have supported the predicted structure of distinct Depression, Anxiety and General Distress factors. The Tripartite model has not been validated in a clinical sample of older adolescents and young adults. The aim of the present study was to examine the validity of the Tripartite model using scale-level data from the MASQ and correlational and confirmatory factor analysis techniques. Methods 137 young people (M = 17.78, SD = 2.63 referred to a specialist mental health service for adolescents and young adults completed the MASQ and diagnostic interview. Results All MASQ scales were highly inter-correlated, with the lowest correlation between the depression- and anxiety-specific scales (r = .59. This pattern of correlations was observed for all participants rating for an Axis-I disorder but not for participants without a current disorder (r = .18. Confirmatory factor analyses were conducted to evaluate the model fit of a number of solutions. The predicted Tripartite structure was not supported. A 2-factor model demonstrated superior model fit and parsimony compared to 1- or 3-factor models. These broad factors represented Depression and Anxiety and were highly correlated (r = .88. Conclusion The present data lend support to the notion that the Tripartite model does not adequately explain the relationship between anxiety and depression in all clinical populations. Indeed, in the present study this model was found to be inappropriate for a help-seeking community sample of older adolescents and young adults.

  8. Investigations of the Circumstellar Disk Fraction as a Function of Mass in Young Embedded Clusters in Orion B

    2016-01-01

    In the current paradigm of star formation, all stars form with circumstellar disks. However, recent studies of the young NGC 2264 clusters (age ~ 2Myr, Marinas et al 2013; 2015) have unexpectedly revealed that stars with masses less than 0.3 solar masses exhibit a lower circumstellar disk fraction than more massive stars in the clusters. Is it possible that a significant number of very low mass stars form without a disk? To answer this, we are studying three very young embedded clusters (ageOrion B Molecular Cloud. For these clusters, we are determining the disk fraction as a function of spectral type and inferred mass. Since the clusters are very young, the disk fractions should represent the initial frequency distribution of disks in these clusters. We are using FLAMINGOS NIR spectroscopy (Levine PhD UF 2006) and photometry to estimate the masses of the stars and FLAMINGOS JHK and Spitzer photometry to estimate the disk frequency of our spectroscopic sample. Our work should provide valuable insights toward understanding the formation and early evolution of circumstellar disks around low mass stars in embedded clusters.

    Usually, a loose stellar distribution can be classified as an OB stellar group, an association, or a young open cluster. We make use of comparisons with the typical OB association Vul OB1. In the present paper we discuss the nature of Bochum 1, a typical example of an object affected by the above classification problem.The field-decontaminated CMD of Bochum 1 presents main sequence (MS) and pre-main sequence (PMS) stars. We report two new small angular-size, compact young clusters and one embedded cluster in the area of Bochum 1. Vul OB1 harbours the young open cluster NGC 6823 and the very compact embedded cluster Cr 404. The Vul OB1 association includes the H II region Sh2-86, and its stellar content is younger ($\\approx3$ Myr) than that of Bochum 1 ($\\approx9$ Myr), which shows no gas emission. Bochum 1 harbours one of the newly found compact clusters as its core. The RDP of Bochum 1 is irregular and cannot be fitted by a King-like profile, which suggests important erosion or dispersion of stars from a pri...

    Full Text Available Abstract Background Anaemia is an important problem amongst young children living in rural India. However, there has not previously been a detailed study of the biological aetiology of this anaemia, exploring the relative contributions of iron, vitamin B12, folate and Vitamin A deficiency, inflammation, genetic haemoglobinopathy, hookworm and malaria. Nor have studies related these aetiologic biological factors to household food security, standard of living and child feeding practices. Barriers to conducting such work have included perceived reluctance of village communities to permit their children to undergo venipuncture, and logistical issues. We have successfully completed a community based, cross sectional field study exploring in detail the causes of anaemia amongst young children in a rural setting. Methods and design A cross sectional, community based study. We engaged in extensive community consultation and tailored our study design to the outcomes of these discussions. We utilised local women as field workers, harnessing the capacity of local health workers to assist with the study. We adopted a programmatic approach with a census rather than random sampling strategy in the village, incorporating appropriate case management for children identified to have anaemia. We developed a questionnaire based on existing standard measurement tools for standard of living, food security and nutrition. Specimen processing was conducted at the Primary Health Centre laboratory prior to transport to an urban research laboratory. Discussion Adopting this study design, we have recruited 415 of 470 potentially eligible children who were living in the selected villages. We achieved support from the community and cooperation of local health workers. Our results will improve the understanding into anaemia amongst young children in rural India. However, many further studies are required to understand the health problems of the population of rural India, and

    Full Text Available Abstract Background Despite the known health and healthcare costs of untreated chlamydia infection and the efforts of the National Chlamydia Screening Programme (NCSP to control chlamydia through early detection and treatment of asymptomatic infection, the rates of screening are well below the 2010-2011 target rate of 35%. General Practitioner (GP surgeries are a key venue within the NCSP however; previous studies indicate that GP surgery staff are concerned that they may offend their patients by offering a screen. This study aimed to identify the attitudes to, and preferences for, chlamydia screening in 15-24 year old men and women attending GP surgeries (the target group. Methods We undertook 36 interviews in six surgeries of differing screening rates. Our participants were 15-24 year olds attending a consultation with a staff member. Data were analysed thematically. Results GP surgeries are acceptable to young people as a venue for opportunistic chlamydia screening and furthermore they think it is the duty of GP surgery staff to offer it. They felt strongly that it is important for surgery staff to have a non-judgemental attitude and they did not want to be singled out as 'needing' a chlamydia screen. Furthermore, our sample reported a strong preference for being offered a screen by staff and providing the sample immediately at the surgery rather than taking home a testing kit. The positive attitude and subjective norms demonstrated by interviewees suggest that young peoples' behaviour would be to accept a screen if it was offered to them. Conclusion Young people attending GP surgeries have a positive attitude towards chlamydia screening and given the right environment are likely to take up the offer in this setting. The right environment involves normalising screening by offering a chlamydia screen to all 15-24 year olds at every interaction with staff, offering screening with a non-judgemental attitude and minimising barriers to screening

  12. CCA transport in soil from treated-timber posts: pattern dynamics from the local to regional scale

    Full Text Available Winegrape growing in many parts of the world, including Marlborough, New Zealand, uses treated-timber posts to act as supports for the grapevine's canopy. At a density of 580 posts per hectare, the H4-process treated supports result in an areal loading of CCA of: Copper (12 kg-Cu ha−1, Chromium (21 kg-Cr ha−1 and Arsenic (17 kg-As ha−1. Arsenic is the most mobile and toxic of the CCA-treatment cocktail. We describe experiments which indicate that about 4–6 mg-As month−1 post−1 is released from the subterranean part of the post. We have used SPASMO (Soil Plant Atmosphere System Model to predict post-to-soil leakage, as well as the pattern dynamics of leaching and exchange around the post. Locally the pattern dynamics of transport and fate are controlled by the soil's chemical characteristics and the prevailing weather. Over its 20-year lifetime, the concentration of arsenic, both that adsorbed on the soil and in the soil solution, exceeds guideline values for soils (100 mg-As kg−1 and drinking water (10 μg-As L−1. Under a regime of 5% annual replacement of posts, the spatially averaged concentration of arsenic leaching through the soil is predicted to rise to 1.25 to 1.7 times the drinking water standard, depending only slightly on the soil type. The steady value is primarily controlled by the arsenic-release rate from the post. These steady values were used in a simple hydrogeological model of the major Marlborough aquifer systems to determine whether the subterranean flow of water could dilute the descending plumes of arsenic coming from above. Except for the sluggish aquifers of the southern valleys in Marlborough, most of the aquifer systems seem capable of diluting the leachate to between one tenth and one twentieth of the drinking water standard. The upscaling of our modelling of the local pattern dynamics spanned six orders of spatial

    Substantial evidence links greater impulsivity and stress exposure to poorer smoking cessation outcomes. Results from adolescents also indicate that stress-related change in risk taking can impede cessation attempts. We investigated the effects of stress-related change in impulsivity, risk taking, attention and nicotine withdrawal, and craving in young adult smokers on time to smoking relapse in a relapse analogue paradigm. Twenty-six young adult smokers (50% women; mean age: 20.9 ± 1.8) were exposed to a stress imagery session followed by a contingency management-based relapse analogue paradigm. Participants smoked at least 5 cigarettes daily, with a mean baseline carbon monoxide (CO) level of 13.7 (±5.1) ppm. Repeated measures analysis of variance (ANOVA) and paired t tests examined stress induction validity and Cox regressions of proportional hazards examined the effects of stress-related changes in nicotine withdrawal, nicotine craving, attention, impulsivity, and risk taking on time to relapse. While stress-related change in impulsivity, nicotine craving and withdrawal did not predict time to relapse (all ps > .10), greater stress-related increases in reaction time (RT) variability (p = .02) were predictive of shorter time to relapse, with trend-level findings for inattention and risk taking. Furthermore, changes in stress-related risk taking affected outcome in women more than in men, with a significant relationship between stress-related change in risk taking only in women (p = .026). Smoking cessation attempts in young adults may be adversely impacted by stress-related increases in risk taking and attentional disruption. Clinicians working with young adults attempting cessation may need to target these stress-related impairments by fostering more adaptive coping and resilience.

  15. The urine circulating cathodic antigen (CCA dipstick: a valid substitute for microscopy for mapping and point-of-care diagnosis of intestinal schistosomiasis.

    Directory of Open Access Journals (Sweden)

    José Carlos Sousa-Figueiredo

    Full Text Available BACKGROUND: The World Health Organization now recommends the provision of praziquantel treatment to preschool-aged children infected with schistosomiasis. For intestinal schistosomiasis the current operational field diagnostic standard is examination of a thick Kato-Katz smear by microscopy prepared from a single stool specimen, and although pragmatic, this methodology has well-known shortcomings. Here, as a potential alternative, the performance of the urine circulating cathodic antigen (CCA dipstick test was assessed in terms of disease-mapping and point-of-care diagnosis for intestinal schistosomiasis in preschool-aged children. Our manuscript reports on findings at baseline and at the end of a one-year longitudinal treatment study. METHODOLOGY/PRINCIPAL FINDINGS: A total of 925 children (mean age 2.8 years were initially recruited from six lakeshore villages representative of high, moderate and low levels of disease transmission. At baseline, all children were tested for intestinal schistosomiasis by microscopic examination of duplicate Kato-Katz smears prepared from a single stool faecal, by antigen detection with the urine CCA dipstick test and by serology with a commercially available ELISA test (as 'gold-standard' that measures host antibody titres to soluble egg antigens. As a point-of-care diagnosis, the urine CCA dipstick test achieved sensitivity and specificity values ranging from 52.5-63.2% and 57.7-75.6%, respectively, with faecal microscopy achieving very high specificities (>87% but sensitivities as low as 16.7% in the low transmission setting. CONCLUSION/SIGNIFICANCE: The urine CCA test was shown to be more effective than faecal microscopy especially in lower transmission settings. The diagnostic performance of this test was not significantly impacted by treatment history or co-infections with other intestinal helminths.

  16. The Clock Protein CCA1 and the bZIP Transcription Factor HY5 Physically Interact to Regulate Gene Expression in Arabidopsis

    The circadian clock regulates the expression of an array of Arabidopsis genes such as those encoding the LIGHT-HARVESTING CHLOROPHYLL A/B (Lhcb) proteins. We have previously studied the promoters of two of these Arabidopsis genes-Lhcb1*1 and Lhcb1*3-and identified a sequence that binds the clock protein CIRCADIAN CLOCK ASSOCIATED 1 (CCA1). This sequence, designated CCAl-binding site (CBS), is necessary for phytochrome and circadian responsiveness of these genes. In close proximity to this sequence, there exists a G-box core element that has been shown to bind the bZIP transcription factor HY5 in other light-regulated plant promoters. In the present study, we examined the importance of the interaction of transcription factors binding the CBS and the G-box core element in the control of normal circadian rhythmic expression of Lhcb genes. Our results show that HY5 is able to specifically bind the G-box element in the Lhcb promoters and that CCA1 can alter the binding activity of HY5. We further show that CCA1 and HY5 can physically interact and that they can act synergistically on transcription in a yeast reporter gene assay. An absence of HY5 leads to a shorter period of Lhcb1*1 circadian expression but does not affect the circadian expression of CATALASE3 (CAT3), whose promoter lacks a G-box element. Our results suggest that interaction of the HY5 and CCA1 proteins on Lhcb promoters is necessary for normal circadian expression of the Lhcb genes.

    This is the first paper of a series devoted to the Lambda Orionis star-forming region, from the X-ray perspective, which will provide a comprehensive view of this complex region. In this paper we focus in uncovering the population of the central, young cluster Collinder 69 (C69), and in particular those diskless members not identified by previous near- and mid-infrared surveys, and to establish the X-ray luminosity function for the association. We have combined two exposures taken with the XMM-Newton satellite with an exhaustive data set of optical, near- and mid-infrared photometry to assess the membership of the X-ray sources based on color-color and color-magnitude diagrams, as well as other properties, such as effective temperatures, masses and bolometric luminosities. We detected a total of 164 X-ray sources, of which 66 are probable and possible cluster members. A total of 16 are newly identified probable members. The two XMM-Newton pointings east and west of the cluster center have allowed us to verify...

    Background and Purpose Positive family history (FH+) of cardiovascular disease (CVD) is a risk factor for own CVD. We aimed to analyze the effect of different types of FH (stroke, coronary heart disease (CHD), peripheral artery disease (PAD) on carotid intima-media thickness (cIMT) in young and middle-aged ischemic stroke patients. Methods First-degree FH of CVD was assessed in ischemic stroke patients ≤ 60y using a standardized interview. Carotid ultrasound was performed and far wall cIMT in three carotid artery segments was registered, representing the common carotid (CCA-IMT), carotid bifurcation (BIF-IMT) and the internal carotid artery (ICA-IMT). Measurements were compared between FH+ and FH negative groups and stepwise backward regression analyses were performed to identify factors associated with increased cIMT. Results During the study period 382 patients were enrolled, of which 262 (68%) were males and 233 (61%) reported FH of CVD. Regression analyses adjusting for risk factors revealed age as the most important predictor of cIMT in all segments. The association between FH+ and cIMT was modified by age (p = 0.014) and was significant only regarding ICA-IMT. FH+ was associated with increased ICA-IMT in patients aged < 45y (p = 0.001), but not in patients ≥ 45y (p = 0.083). The association with ICA-IMT was present for a FH of stroke (p = 0.034), but not a FH+ of CHD or PAD. Conclusions FH of stroke is associated with higher ICA-IMT in young ischemic stroke patients. Subtyping of cardiovascular FH is important to investigate heredity in young ischemic stroke patients. Trial Registration ClinicalTrials.gov NCT01597453 PMID:27504830

    2010-03-01

    Full Text Available Abstract Background Muscle strength is important for young people with Down syndrome as they make the transition to adulthood, because their workplace activities typically emphasise physical rather than cognitive skills. Muscle strength is reduced up to 50% in people with Down syndrome compared to their peers without disability. Progressive resistance training improves muscle strength and endurance in people with Down syndrome. However, there is no evidence on whether it has an effect on work task performance or physical activity levels. The aim of this study is to investigate if a student-led community-based progressive resistance training programme can improve these outcomes in adolescents and young adults with Down syndrome. Methods A randomised controlled trial will compare progressive resistance training with a control group undertaking a social programme. Seventy adolescents and young adults with Down syndrome aged 14-22 years and mild to moderate intellectual disability will be randomly allocated to the intervention or control group using a concealed method.

    Full Text Available The intrinsic purpose of this study was to investigate empirically that how young consumers’ intention to buy the counterfeited fashion products is empowered by selected personality traits, such as fashion consciousness, public self-consciousness, ethical obligation and ethical judgment. The research was carried out on a sample of N = 269 respondents of different age groups and gender. Data for this study were collected by using a structured questionnaire containing six tiers, where Section-I contains seven statements using Likert scale, to assay the consumers’ degree of fashion consciousness. Section-II deals with the questions related to the consumers’ degree of public self consciousness. Section-III and IV contains two and three statements respectively to measure the consumers’ degree of ethical obligation and ethical judgment. Two items were used in Section-V to measure the consumers’ intention to buy the fashion counterfeits in the future. Questions related to the consumers’ demographical profile were asked in Section-VI. One-Way ANOVA was employed to test the proposed hypothesis. To determine among which groups the true differences prevail, the Duncan Multiple Range Test was performed. It was disclosed that the young consumers with high level of fashion consciousness and public self consciousness are more interested in buying the counterfeited fashion products. On the ethical grounds, it was divulged that the consumers who think it as an unethical practice to buy the counterfeited products are less likely to buy the counterfeited brands.

    The effect of liquid calories on short-term energy compensation is a topic that justifies further investigation. Whilst previous studies appear to vary widely in terms of protocol, design and outcomes, none have placed much focus on possible gender differences in compensation. This study investigated the impact of isocaloric (150kcal) portions of a sucrose sweetened fruit drink (SSD), orange juice (OJ) and semi-skimmed milk (M) on subjective hunger and food intake at a subsequent ad libitum buffet consisting of a large variety of foods, and compared their effects with a calorie free (artificially sweetened) fruit drink control (CTRL). Forty-seven young adults (24 females and 23 males) were provided a standard breakfast which was followed 3h later by the preload beverage and 1h later by lunch. Participants rated hunger, fullness and desire to eat throughout the study period. Compared to the CTRL, males demonstrated a good caloric compensation at lunch following all three treatment beverages, whilst females reduced food intake following M. Total energy intake (energy in preload+energy intake at lunch) by males was similar across all four beverage conditions whilst females showed an increased total energy intake following SSD compared to the CTRL. The study indicates that the consumption of caloric beverages may not be affecting total energy intake in males in the short-term even in the presence of a large selection of palatable foods. On the other hand, females appeared to show a possible dysregulation, which requires further investigation. PMID:20546812

    Previous research suggests that bilinguals demonstrate superior cognitive control processes than monolinguals. The goal of the current investigation was to examine whether this “bilingual advantage” is observed in a language processing task that requires inhibition, i.e., lexical ambiguity processing. Monolingual and bilingual participants read sentences that biased the reading of a terminal homonym toward the subordinate or dominant reading (e.g., The doctor asked her to step onto the scale.). A relatedness judgment was made on target words that were related to the contextually appropriate (e.g., balance) or inappropriate meaning (e.g., skin), or unrelated to either meaning (e.g., shoe) while electrophysiological recording took place. The results revealed subtle processing differences between monolinguals and bilinguals that were evident in electrophysiological measures, but not in behavioral measures. These findings suggest that monolinguals rely on context to access the contextually appropriate meaning of a homonym to a greater extent than bilinguals, while bilinguals demonstrate simultaneous activation of both meanings.

    To investigate the safety and tolerability of the atypical antipsychotic quetiapine in anorexia nervosa patients, and to determine the effect of quetiapine treatment on anorexic psychopathology and other key outcome measures including weight and body image, we conducted a naturalistic, open-label, 12-week randomized controlled trial of low-dose (100-400 mg/day) quetiapine treatment versus treatment as usual in 33 anorexia nervosa patients from our Eating Disorder Clinics. To monitor the effects of treatment over the medium term, the participants were then followed up with assessment visits at 6 and 12 months after the end of the treatment phase. Low-dose quetiapine treatment resulted in both psychological and physical improvements, with minimal associated side-effects. Given the overall trend toward improvement that we observed, quetiapine appears to be a promising candidate for the treatment of anorexia nervosa. Further large-scale placebo-controlled clinical trials will be necessary to fully evaluate the benefits of quetiapine treatment for this disorder. PMID:20447652

    Full Text Available Accurate diagnostic techniques for schistosomiasis are essential for prevalence determination and identification of positive patients. A point-of-care test for detecting schistosome circulating cathodic antigen (POC-CCA has been evaluated for its accuracy in different endemic regions. This reagent strip/dipstick based assay has showed high sensitivity for individuals with high or moderate worm burden, but the interpretation of light infections is less clear, especially for trace readings.We introduced a urine lyophilization step to the POC-CCA assay to improve its sensitivity and clarify the interpretation of traces. We evaluated POC-CCA sensitivity and specificity within individuals with low parasite burdens in a Brazilian endemic area where a high number of traces were detected. Patients that were positive for other helminths were also evaluated for cross reactions. In all cases, a combined parasitological diagnosis using Kato-Katz (24 slides and Saline Gradient (1 g of feces were used as reference. At baseline, diagnosis by POC-CCA (1-2 cassettes showed 6% sensitivity, inaccurately predicting a low prevalence of Schistosoma mansoni infections (2 POC-CCA positives/32 egg positives. After urine lyophilization, the sensitivity was increased significantly (p < 0.05. Prevalence rates changed from 2% to 32% (27 POC-CCA positives/32 egg positives, equivalent to parasitological techniques. Most of the trace readings changed to positive after lyophilization while some negatives turned into traces. Cross reaction analysis confirmed the specificity of POC-CCA.Trace readings cannot be primarily defined as positive or negative cases. It is critical to verify case-by-case by concentrating urine 10 fold by lyophilization for the diagnosis. Following lyophilization, persistent trace readings should be read as negatives. No trained technician is needed and cost is restricted to the cost of a lyophilizer and the electricity to run it.

    Melatonin (N-acetyl-5-methoxytryptamine) is an important regulator of circadian rhythms and immunity in animals. However, the diurnal changes of endogenous melatonin and melatonin-mediated diurnal change of downstream responses remain unclear in Arabidopsis. Using the publicly available microarray data, we found that the transcript levels of two melatonin synthesis genes (serotonin N-acetyltransferase (SNAT) and caffeate O-methyltransferase (COMT)) and endogenous melatonin level were regulated by diurnal cycles, with different magnitudes of change. Moreover, the transcripts of C-repeat-binding factors (CBFs)/Drought response element Binding 1 factors (DREB1s) were co-regulated by exogenous melatonin and diurnal changes, indicating the possible correlation among clock, endogenous melatonin level and AtCBFs expressions. Interestingly, diurnal change of plant immunity against Pst DC3000 and CIRCADIANCLOCK ASSOCIATED 1 (CCA1) expression were largely lost in AtCBFs knockdown line-amiR-1. Taken together, this study identifies the molecular pathway underlying the diurnal changes of immunity in Arabidopsis. Notably, the diurnal changes of endogenous melatonin may regulate corresponding changes of AtCBF/DREB1s expression and their underlying diurnal cycle of plant immunity and AtCCA1. PMID:26828406

  13. Impact of fixation/drying conditions on fixation rate, leachability and bioefficacy in CCA-C treated red pine and southern pine

    Red pine (Pinus resinosia Ait) and southern pine (Pinus spp.) sapwood blocks were pressure treated with CCA-C at retention of 6.4, 2.0, 1.5 kg?m-3 followed by fixation using 11 post-treatment schedules ranging from 50-70 °C and 5 different relative humidity conditions. The effect of these post-treatment schedules on fixation rate, chemical leachability and decay resistant once were evaluated to better understand the effects of fixation/drying conditions on leachability and biodeterioration. Southern pine blocks fixes slightly slower than red pine. Fixation of CCA at high temperature high humidity, essential initially fixation at high humidity for fixation/drying schedules, resulted in lower leaching of chromium and arsenic elements than high temperature low humidity or initially fixation at the high temperature low humidity conditions. Copper leaching was indicated no significant difference under 11 fixation/drying conditions for both species. Weight losses for southern pine by Chaetomium globosum was lower than red pine by Gloeophyllom trabeum. There were some different capacities of decay resistance for both species under those post treatment conditions.

    Full Text Available The highly toxic Cr(VI is a critical component in the Chromated Copper Arsenate (CCA formulations extensively employed as wood preservatives. Remediation of CCA mixed waste and discarded treated wood products is a significant challenge. We demonstrate that UV/TiO2 photocatalysis effectively reduces Cr(VI to less toxic Cr(III in the presence of arsenate, As(V, and copper, Cu(II. The rapid conversion of Cr(VI to Cr(III during UV/TiO2 photocatalysis occurs over a range of concentrations, solution pH and at different Cr:As:Cu ratios. The reduction follows pseudo-first order kinetics and increases with decreasing solution pH. Saturation of the reaction solution with argon during UV/TiO2 photocatalysis had no significant effect on the Cr(VI reduction demonstrating the reduction of Cr(VI is independent of dissolved oxygen. Reduction of Cu(II and As(V does not occur under the photocatalytic conditions employed herein and the presence of these two in the tertiary mixtures had a minimal effect on Cr(VI reduction. The Cr(VI reduction was however, significantly enhanced by the addition of formic acid, which can act as a hole scavenger and enhance the reduction processes initiated by the conduction band electron. Our results demonstrate UV/TiO2 photocatalysis effectively reduces Cr(VI in mixed waste streams under a variety of conditions.

    Crossed cerebellar atrophy (CCA) was investigated by X-ray CT to establish the incidence, mechanism, and the relation to cerebral lesions in 130 cases of unilateral supratentorial cerebrovascular diseases. The cases consisted of 83 males and 47 females with cerebral infarction (65) and cerebral hemorrhage (65). The patients' average age was 57.6 years. Crossed cerebellar atrophy was demonstrated in 8 cases (6.2%), 6 of whom had massive cerebral infarction in the middle cerebral artery area (9.2%). The six cases of CCA caused by cerebral infarction had lesions in the frontal and temporal lobes. Two had a cerebral hemorrhage in the putamen and in the thalamus, respectively, accounting for 3.1% of the cases of cerebral hemorrhage. One case had putaminal hemorrhage, and another had thalamic hemorrhage. Cerebrovascular stroke had occured in these patients with CCA more than 2 months previously. In 5 of the 8 cases of CCA, atrophy was present in the basis pedunculi and the basis pontis on the side of the cerebral lesion. However, neither dilation nor deformity of the fourth ventricle was present in any of the patients, suggesting that none of the CCA patients had atrophy of the dentate nucleus. The CCA patients had massive cerebral lesion in the frontal and temporal lobes or atrophy of the basis pedunculi and basis pontis, suggesting the presence of the transsynaptic degeneration of the cortico-ponto-cerebellar pathway. In the case of the thalamic hemorrhage, who had not hemorrhagic lesion in the frontal and temporal lobes, atrophy of the basis peduncli and basis pontis was not observed. Though dilation or deformity of the fourth ventricle is not observed in this case, presence of the degeneration of the dentate-rubro-thalamic pathway cannot be denied. CCA seems to be caused by both the transsynaptic degeneration of the cortico-ponto-cerebellar pathway and the dentate-rubro-thalamic pathway.

    Full Text Available Studies have shown that ticks are susceptible to infection by entomopathogenic nematodes. These studies indicate different susceptibilities of ticks to infection by these fungi, depending on the tick species, development phase, entomopathogenic nematodes species and strains and the time the ticks are exposed to them. Usually this period ranges from 24 to 72 hours. The aim of this study was to evaluate the infection times in vitro of engorged Rhipicephalus (Boophilus microplus females by the entomopathogenic nematodes Steinernema glaseri CCA strain, by analysis of the ticks' biological parameters. The results show that a 2-hour exposure time was sufficient for the engorged R. microplus females to be infected by S. glaseri CCA, but that a minimum exposure time of 24 hours was necessary to generate treatment efficacy above 90%.Os carrapatos são susceptíveis à infecção por nematoides entomopatogênicos.

    This study engages with the culture-centered approach (CCA) to explore Chinese immigrant restaurant workers' perception of the U.S. health care system and their interactions with the health care system in interpreting meanings of health. Chinese restaurant workers are marginalized because of their struggles on the job, their immigrant identity, and their negotiations with the structural contexts of occupation, migration status, and culture. In-depth interviews were conducted with 18 Chinese immigrant restaurant workers that lasted an average of 1.5 hours each, and were audiotaped. Interviews with participants highlighted critical issues in access to health care and the struggles experienced by restaurant workers in securing access to health, understood in the context of work. Critical to the workers' discourse is the acknowledgment of structural constraints such as lack of insurance coverage, immigration status, and lack of understanding of how the U.S. health care system works.

    Background Clinical research often lacks participants of young age. Adding to the small amount of scientific studies that focus on the population entering adulthood, there are also difficulties to recruit them. To overcome this, there is a need to develop and scientifically evaluate modes for data collection that are suitable for adolescents and young adults. With this in mind we performed 39 online focus group discussions among young survivors of childhood cancer to explore thoughts and experiences around dating, being intimate with someone, and having children. Objective The aim of the study was to evaluate online focus group discussions as a mode for data collection on sensitive issues among young persons with a cancer experience. Methods One hundred thirty-three young persons (16-25 years) previously diagnosed with cancer, participated in 39 synchronous online focus group discussions (response rate 134/369, 36%). The mode of administration was evaluated by analyzing participant characteristics and interactions during discussions, as well as group members’ evaluations of the discussions. Results Persons diagnosed with central nervous tumors (n=30, 27%) participated to a lower extent than those with other cancer types (n=103, 39%; χ 2= 4.89, P=.03). The participants described various health impairments that correspond to what would be expected among cancer survivors including neuropsychiatric conditions and writing disabilities. Even though participants were interested in others’ experiences, sexual issues needed more probing by the moderators than did fertility-related issues. Group evaluations revealed that participants appreciated communicating on the suggested topics and thought that it was easier to discuss sex when it was possible to be anonymous toward other group members. Conclusions Online focus group discussions, with anonymous participation, are suggested to be a feasible and valid mode for collecting sensitive data among young persons with a

    Flow parameters can induce pathological changes in the arteries. We propose a method to asses those parameters using a 3D computer model of the flow in the Common Carotid Artery. Input data was acquired using an automatic 2D ultrasound wall tracking system. This data has been used to generate a 3D geometry of the artery. The diameter and wall thickness have been assessed individually for every patient, but the artery has been taken as a 75mm straight tube. The Young's modulus for the arterial walls was calculated using the pulse pressure, diastolic (minimal) diameter and wall thickness (IMT). Blood flow was derived from the pressure waveform using a 2-parameter Windkessel model. The blood is assumed to be non-Newtonian. The computational models were generated and calculated using commercial code. The coupling method required the use of Arbitrary Lagrangian-Euler formulation to solve Navier-Stokes and Navier-Lame equations in a moving domain. The calculations showed that the distention of the walls in the model is not significantly different from the measurements. Results from the model have been used to locate additional risk factors, such as wall shear stress or circumferential stress, that may predict adverse hypertension complications.

    We identify young, pre-main sequence stars in the SW Bar region of the Small Magellanic Cloud (SMC) using color magnitude diagrams obtained by the Hubble Space Telescope as part of the SMIDGE survey. Deep, panchromatic, high spatial resolution Hubble imaging provides an excellent dataset for studying young, low-mass (~2-0.5 M⊙) stellar populations. The SW Bar region observed by SMIDGE contains multiple low mass star forming regions in various stages of evolution. These regions provide contrast to massive regions previously surveyed by Hubble in the SMC (e.g., NGC346, NGC602), and allow us to explore the evolution from quiescent clouds to HII regions. We analyze the spatial distribution of these young stars and their association with the local ISM, inferred from observations of molecular gas and dust emission. Additionally, we use Hα imaging to constrain accretion rates for the pre-MS stars. Finally, we analyze the characteristics and multiplicity of Spitzer YSO detections as revealed by high spatial resolution imaging.

    This is a thorough investigation into contemporary young people and their media life. The article conceptualizes a typology of media life, drawing on a theoretical body involving the sociology of generations, life course research, media life and individualization. This empirically derived typology...... makes a strong instrument for an understanding of the media life of the young, furnishing insights into how they have constructed their use of media. The investigation is based on a robust national survey with Swedes born 1994–2001, conducted in 2010, and focusing on four media: television, gaming......, the Internet and mobile devices. Two of the findings are particularly surprising. Firstly, the results reveal that the young generally lead heterogeneous media lives, varying with age and sex. Secondly, although some young people literarily live their life in media, there are also de facto young who live...

    Full Text Available A intensa exploração econômica tem causado diminuição do estoque original das espécies madeireiras amazônicas, incluindo aquelas de alta durabilidade natural destinadas a usos em contato com o solo. A escassez dessas madeiras resulta na elevação do preço, inviabilizando economicamente seu uso, sendo uma alternativa a substituição por espécies plantadas de rápido crescimento tratadas com preservativos. Outra vantagem, além da econômica, de utilizar espécies plantadas em substituição às tradicionais é ambiental, pois reduzirá a pressão exploratória sobre aquelas. Este estudo teve por objetivo avaliar o grau de degradação biológica de madeira de eucalipto citriodora (Corymbia citriodora (Hook. K.D. Hill & L.A.S.

  15. Pathways of Pb and Mn observed in a 5-year longitudinal investigation in young children and environmental measures from an urban setting

    International Nuclear Information System (INIS)

    We monitored 108 children ≤5 years on a 6-month basis for up to 5 years in a major urban setting. Samples (n ∼ 7000) included blood, urine, handwipes (interior, and after exterior playing), 6-day duplicate diet, drinking water, interior house and day care dust-fall accumulation using petri dishes, exterior dust-fall accumulation, exterior dust sweepings, paint, soil and urban air. The geometric mean blood Pb (PbB) was 2.1 μg/dL and blood Mn (MnB) was 10.0 μg/L. Following a path modelling approach, mixed model analyses for a fully adjusted model showed the strongest associations for PbB were with interior house dust and soil; for MnB there were no significant associations with any predictors. Predictor variables only explained 9% of the variance for Pb and 0.7% for Mn. Relationships between environmental measures and PbB in children are not straightforward; soil and dust sweepings contribute only about 1/5th of the amounts to PbB found in other studies. - Highlights: • 5-year longitudinal study of young children in urban setting. • Samples analysed for Pb and Mn in blood and environmental samples. • Modified structural equation modelling. • Strongest associations for blood Pb with house dust and soil. • Soil and dust contribute very small amounts to blood Pb. - This study provides useful insights about the environmental pathways leading to Pb and Mn exposure in young children

    Black-oil, compositional and thermal simulators have been developed to address different physical processes in reservoir simulation. A number of different types of discretization methods have also been proposed to address issues related to representing the complex reservoir geometry. These methods are more significant for fractured reservoirs where the geometry can be particularly challenging. In this project, a general modular framework for reservoir simulation was developed, wherein the physical models were efficiently decoupled from the discretization methods. This made it possible to couple any discretization method with different physical models. Oil characterization methods are becoming increasingly sophisticated, and it is possible to construct geologically constrained models of faulted/fractured reservoirs. Discrete Fracture Network (DFN) simulation provides the option of performing multiphase calculations on spatially explicit, geologically feasible fracture sets. Multiphase DFN simulations of and sensitivity studies on a wide variety of fracture networks created using fracture creation/simulation programs was undertaken in the first part of this project. This involved creating interfaces to seamlessly convert the fracture characterization information into simulator input, grid the complex geometry, perform the simulations, and analyze and visualize results. Benchmarking and comparison with conventional simulators was also a component of this work. After demonstration of the fact that multiphase simulations can be carried out on complex fracture networks, quantitative effects of the heterogeneity of fracture properties were evaluated. Reservoirs are populated with fractures of several different scales and properties. A multiscale fracture modeling study was undertaken and the effects of heterogeneity and storage on water displacement dynamics in fractured basements were investigated. In gravity-dominated systems, more oil could be recovered at a given pore

Based on the analysis of these factors, the paper put forward some countermeasures to help young children overcome weariness, including that parents must have the courage to admit their mistakes, the teacher education actively cooperate with the parents to student work, schools to cultivate student's interpersonal relationship counseling students self-esteem and self-confidence, and to create a good social environment for young children and so on.

  19. An RNA-binding complex involved in ribosome biogenesis contains a protein with homology to tRNA CCA-adding enzyme.

    Full Text Available A multitude of proteins and small nucleolar RNAs transiently associate with eukaryotic ribosomal RNAs to direct their modification and processing and the assembly of ribosomal proteins. Utp22 and Rrp7, two interacting proteins with no recognizable domain, are components of the 90S preribosome or the small subunit processome that conducts early processing of 18S rRNA. Here, we determine the cocrystal structure of Utp22 and Rrp7 complex at 1.97 Å resolution and the NMR structure of a C-terminal fragment of Rrp7, which is not visible in the crystal structure. The structure reveals that Utp22 surprisingly resembles a dimeric class I tRNA CCA-adding enzyme yet with degenerate active sites, raising an interesting evolutionary connection between tRNA and rRNA processing machineries. Rrp7 binds extensively to Utp22 using a deviant RNA recognition motif and an extended linker. Functional sites on the two proteins were identified by structure-based mutagenesis in yeast. We show that Rrp7 contains a flexible RNA-binding C-terminal tail that is essential for association with preribosomes. RNA-protein crosslinking shows that Rrp7 binds at the central domain of 18S rRNA and shares a neighborhood with two processing H/ACA snoRNAs snR30 and snR10. Depletion of snR30 prevents the stable assembly of Rrp7 into preribosomes. Our results provide insight into the evolutionary origin and functional context of Utp22 and Rrp7.

    As jittery consumers in the West have tightened their belts in the hope of weathering the financial woes,emerging markets like China have become a possible panacea for multinational faltering businesses. Although many brands still admit that China is a quite complex market to enter,however,just because of its diverse possibilities,more potential markets can be rendered. At present,the consumption of Chinese young generation forms a thriving market. Because young consumers are usually impressed with a positive,up-market perception of foreign department stores,and they tend to become more brand-oriented than purely price sensitive,and willing to pay a premium for better quality. Therefore,operators can take advantage of this to further set up their brand image…

  3. Transport of monovalent cations and calcium in erythrocytes from spontaneously hypertensive rats: investigations with fractions enriched with young and old cells

    International Nuclear Information System (INIS)

    The erythrocytes from two spontaneously hypertensive rat strains (SHR and MHS) differ from those of control strains such as WKY and MNS in showing lower values of the mean volume and higher Na, K-cotransport rates. After 4-hour incubation in the presence of orthovanadate 45Ca levels in the erythrocytes from SHR was twice as high as in those from WKY. Under the same conditions, hemoglobin crystallization occured, this process in SHR erythrocytes took place more intensively. No difference was found in these parameters between MNS and MHS. The fractions enriched with young and old cells remained to display variations in the mean volume of cells. Na, K-cotransport rates, 45Ca levels and hemoglobin crystallization, which were recorded between SHR and WKY. The WKY-SHP hybrids of second generation indicated that only Na,K-cotransport rates of the parameters examined positively correlated with blood pressures. From the findings it was concluded that the differences in the volume of erythrocytes and their permeability for cations were not due to the changed time course of cell aging in the blood bed, but to the specific characteristics of cytoskeleton protein arrangement, which were primarily typical of a rat reticulocytic membrane

    An integrated cytometric fluorescent imaging system is developed for characterizing chemical concentration and cellular status in microscale cell culture analog (μCCA) devices. A μCCA is used to evaluate the potential toxicity and efficacy of proposed pharmaceutical treatment of animals or humans. The imaging system, based on discrete optical components, not only provides a robust and compact tool for real-time measurements, but the modularity of the system also offers flexibility to be applicable to various μCCA structures that may be appropriate to various animal or human models. We investigate the dynamics of doxorubicin, a chemotherapeutic agent, on cultured cells in a μCCA using the integrated cytometric fluorescent imaging system. This study incorporates two uteran cancer cell lines representing a sensitive cell type and a multi-drug resistant (MDR) derivative cell line. The ultimate goal is to test the effect of MDR modulators in combination with doxorubicin to kill cancer cells while not causing undue harm to normal cells.

    It is shown that innovation is regarded as a central success factor in tackling challenges of the future. Especially in high-wage regions such as Germany companies find themselves in a fierce innovation competition marked by growing challenges at the global level and the growing dynamism of innovation processes. Young industries are typically faced with much uncertainty in regard to strategy and technology, presenting their individual companies, most of them small and young themselves, with the challenge of having to rely on limited resources to develop innovative products, services and processes and launch them on the market. This provides the backdrop to the present dissertation, which inquires into the factors that determine the success of cooperative innovation projects in young branches of industry. Using the German photovoltaic industry as an example, the study empirically determines major determinants of success of joint innovation projects in young industries and derives recommendations for action for the management of companies and innovation networks.

    Full Text Available Violence against women in relationships young people has become in recent years a public health problem of major social. This article, with a view to the prevention, seeks to address the psychological characteristics of the perpetrator of pair in young relations. An initial review of the personality features investigated in previous studies and their influence on violent behaviour was carried out. Following this, an empirical study on a sample of young people was performed. Methods: We conducted a study with 100 young people of Valencia. Of these, 50 are young offenders and 50 couple, young students of compulsory secondary education. Data are obtained and analyzed psychological characteristics differences between groups. Results: The study conducted shows that in general, young offenders have one hand high scores on neuroticism, impulsivity, external locus of control, psychoticism and antisocial behavior. Furthermore show low scores on self-control, empathy, selfesteem and frustration tolerance. Conclusions: The results of this paper make it abundantly clear that violence in young relationships is important enough to be considered from different sectors of society and justifies the need to develop and implement prevention programs adapted adolescents and their characteristics.

  17. Young massive star clusters

    CERN Document Server

    Zwart, Simon Portegies; Gieles, Mark

    2010-01-01

    Young massive clusters are dense aggregates of young stars that form the fundamental building blocks of galaxies. Several examples exist in the Milky Way Galaxy and the Local Group, but they are particularly abundant in starburst and interacting galaxies. The few young massive clusters that are close enough to resolve are of prime interest for studying the stellar mass function and the ecological interplay between stellar evolution and stellar dynamics. The distant unresolved clusters may be effectively used to study the star-cluster mass function, and they provide excellent constraints on the formation mechanisms of young cluster populations. Young massive clusters are expected to be the nurseries for many unusual objects, including a wide range of exotic stars and binaries. So far only a few such objects have been found in young massive clusters, although their older cousins, the globular clusters, are unusually rich in stellar exotica. In this review we focus on star clusters younger than $\\sim100$\\,Myr, m...

  4. Thyroid functions in young diabetics

    International Nuclear Information System (INIS)

    Assessment of the thyroid-pituitary axis was performed in uncontrolled (20 cases) and controlled (22 cases) insulin-dependent young diabetics who were university students attending the university hospital. A third age-matching group (21 normal subjects) was also investigated. The plasma glucose level was determined after fasting as well as 2 hours after an oral glucose meal (50 g). Thyroxine (T4), triiodeothyronine (T3) and thyroid stimulating hormone (TSH) were assayed by RIA. The data obtained showed a lowered level of T3 and T4 and a raised level of TSH in uncontrolled young diabetics as compared to corresponding values for age matching normals. The group of controlled diabetics showed near normal T3 and increased T4 levels, but still lower than normal. TSH levels dropped significantly to the normal level. (author)

    1999-01-01

    Gigahertz Peaked Spectrum (GPS) sources and Compact Symmetric Objects (CSO) are selected in very different ways, but have a significant overlap in properties. Ever since their discovery it has been speculated that they are young objects, but only recently, strong evidence has been provided indicating that GPS sources and CSOs are indeed the young counterparts of large, extended sources. They are therefore the objects of choice to study the initial evolution of extragalactic radio sources. Observational constraints on the luminosity evolution of young radio sources have mainly come from number density statistics and source size distributions, indicating that young sources should decrease in luminosity by a factor ~10 as they evolve to extended objects. We argue that the growth or decay in radio power of the individual objects has a strong influence on the slope of their collective luminosity function. This has led to a new method of constraining the evolution of young sources by comparing their luminosity func...

    2009-01-01

    Background Young adults have the highest smoking rate of any age group in the U.S., and new strategies to decrease young adult smoking are needed. The objective of the current study was to identify psychographic and demographic factors associated with current smoking and quitting behaviors among young adults. Methods Attitudes, social groups, and self-descriptors, including supporting action against the tobacco industry, advertising receptivity, depression, alcohol use, and other factors associated with smoking were tested for associations with smoking behaviors in a 2005 cross-sectional survey of 1528 young adults (aged 18–25 years) from a web-enabled panel. Analyses were conducted in 2007. Results Being older was associated with current smoking, whereas having some higher education and being African American or Hispanic were negatively associated with smoking. Supporting action against the tobacco industry was negatively associated with smoking (AOR=0.34 [95% CI=0.22, 0.52]). Perceived usefulness of smoking, exposure to smokers, increased perceived smoking prevalence, receptivity to tobacco advertising, binge drinking, and exposure to tobacco advertising in bars and clubs were associated with smoking. Supporting action against the tobacco industry was associated with intentions to quit smoking (AOR= 4.43 [95% CI=2.18, 8.60]). Conclusions Young adults are vulnerable to tobacco-industry advertising. Media campaigns that denormalize the tobacco industry and appeal to young adults appear to be a powerful intervention to decrease young adult smoking. PMID:19269128

    2016-04-01

    Young's construction for a contact angle at a three-phase intersection forms the basis of all fields of science that involve wetting and capillary action. We find compelling evidence from recent experimental results on the deformation of a soft solid at the contact line, and displacement of an elastic wire immersed in a liquid, that Young's equation can only be interpreted by surface energies, and not as a balance of surface tensions. It follows that the a priori variable in finding equilibrium is not the position of the contact line, but the contact angle. This finding provides the explanation for the pinning of a contact line.

    Personnel pre-movement time in the gymnasium was studied by fire emergency evacuation drill and questionnaire survey. The Multinominal Logistic Regression Model was applied on analyzing survey data. The result showed that evacuation pre-movement time ( 60 s) respectively is 15. 45 % , 75. 61 % , 8. 94 % and the probability of females evacuation pre-movement time ( 60 s) respectively is 24. 14 % , 39. 72 % , 36. 14%. It showed that different gender has a certain effect on pre-evacuation time. In public buildings represented by the gymnasium, young students pre-movement time is less than 60 s.%通过组织火灾应急疏散逃生演习、现场问卷调查等方式,统计了体育馆内人员的疏散预动作时间,进而建立多分变量逻辑斯蒂回归模型对该统计数据进行了研究.发现:男生选择疏散预动作时间为<30 s的可能性是女生的0.886倍,选择疏散预动作时间为30-60 s的可能性是女生的2.818倍.预测人员疏散预动作时间为<30 s、30 -60 s、>60s的概率,男生分别为15.45%,75.61%、8.94%,而女生分别为24.14%,39.72%、36.14%;研究结果表明:人员性别的不同对疏散预动作时间有一定的影响,在体育馆类建筑中,青少年人员疏散预动作时间基本上小于60 s.

  5. Young Planetary disks

    2007-07-01

    The present review focuses on UV observations of young planetary disks and consequently mostly on the gaseous content of those disks. Few examples are taken to illustrate the capability of the UV observatories to scrutinize in detail the gas content of low density circumstellar disks if they are seen edge-on or nearly edge-on. For instance, in the case of HD100546, FUSE observations re- vealed signatures of outflow and infall in the disk caused by interaction of the stellar magnetosphere with the circumstellar disk. Observations of numerous absorption lines from H2 around young stars give constrains on the gas temper- ature and density, and physical size of the absorbing layer. In the case of T-Tauri stars and one brown dwarf, emissions from exited H2 have been detected. In the case of Beta Pictoris, the observation of CO in the UV and search for H2 with FUSE demonstrated that the evaporation of frozen bodies like comets must produce the CO seen in the disk. Extensive observations of spectral variability of Beta Pictoris are now interpreted by extrasolar comets evaporating in the vicinity of the central star of this young planetary system.

Most of the interviewees are not permanently employed, receiving some 200€ honoraria,and as they have mentioned, executives and editors do not suffi ciently trust them, nor are they aff orded adequate space to express themselves. While Serbia has enacted nominal steps toward democracy over the past ten years, and in the process has reduced the number of persecutions and arrests of journalists and punishments and cancellations of media, more than half of the young journalists surveyed have experienced restraints in freedom of speech while doing their job. Further, ten percent of those surveyed state that they are often censored. The basis of this examination emanates from research on the professional status of ”eternal freelancers”, conducted in 2009 by the Youth Development Fund (Razvojni fond za mlade – RFM expert team, with the support from the Provincial Secretariat for Sport and Youth. In addition, a questionnaire has been filled out by over 50 young journalists from Vojvodina.

    Full Text Available Penalty, including imprisonment comprises one of the basic forms of reaction to crime. It differs from other possible penalties in the degree of discomfort and in the legal consequences. There are also different goals in case of criminal penalty as a legal and social consequence of a crime or misconduct. Imprisonment aims at taking different actions which consequently, should lead to the situation where the criminal does not return to committing crimes. It is so called penitentiary rehabilitation which is a multidimensional phenomenon and it should be considered from the modern society point of view. Its range includes correction of inadequate individual’s behavior and his or her adaptation of norms and values shared by the general public, as well as taking and being persistent in the process of designing oneself, own personality and consistent implementation of the self- vision in the future, organized hierarchically for the given time periods. Therefore, different means and action are taken under the implementation of imprisonment. Moreover, convicted prisoners are divided into different groups in penitentiaries. One of the groups is the group of young convicts. The goal of this article is to examine and describe the opinion of the young convicts on the penitentiary as a penal and rehabilitation institution. To perform the study, sixty young convicts were selected. In the test method, the diagnostic survey was applied. The original authoring questionnaire was used in the study. The study was performed in the Penitentiary in Radom, in December 2012.

    The process of hydration and solidification of young concrete has significant effect on the long term strength and durability of concrete. The electrical property of concrete provides a direct and practical method for monitoring and investigating the hydration process of young concrete. This study developed an advanced system for measurement of electrical parameters, used to study the electrical properties of young concrete. The test results provided the electric parameters for concretes with different water binder ratios and different mineral admixture incorporations. The variations and characteristics of the measured electrical parameters were closely related to the physical and chemical properties of young concrete. These parameters were used to analyze and study the hydration process of young concrete.

    To analyze the SACY (Search for Associations Containing Young stars) survey we developed a method to find young associations and to define their high probability members. These bona fide members enable to obtain the kinematical and the physical properties of each association in a proper way. Recently we noted a concentration in the UV plane and we found a new association we are calling ASYA (All Sky Young Association) for its overall distribution in the sky with a total of 38 bonafide members and an estimated age of 110 Myr, the oldest young association found in the SACY survey. We present here its kinematical, space and Li distributions and its HR diagram.

  5. The young female athlete.

    Science.gov (United States)

    Hurvitz, Michal; Weiss, Ram

    2009-12-01

    Participation of adolescents and young women in strenuous sports activity may lead to various metabolic and psychological derangements of clinical relevance to the endocrinologist. The most common manifestations encountered in practice are primary and secondary amenorrhea, reduced bone mineral density and eating disorders. The occurrence of all three together has been named "the athletic triad". The underlying hormonal drivers that lead to some of these manifestations are the reduced leptin level as well as the persistent low grade stress response commonly observed in such females. "Exercise-related female reproductive dysfunction" (ERFRD), can possibly include short-term (infertility) and long-term (osteoporosis) consequences. Functional hypothalamic amenorrhea, a manifestation of ERFRD in adolescence, is an integrated response to the combination of excessive physical and emotional stress, exercise, and/or reduced food intake characterized by decreased endogenous GNRH secretion. The primary aim of treating these athletes should be the prevention of the development of any component of the triad as well as the whole complex by educating athletes, trainers, parents and health care professionals about proper nutrition and safe training. The long term prognosis is good. However, significant long term morbidity may affect these young women later in life. PMID:20118893

    1995-04-01

    In every country, people debate about at what point youth should be informed about sex, if it is normal to be sexually active and at what age, and if it is necessary for youth to have easy access to condoms and other contraceptive methods. The reason for the debate is that young people are being exposed to more and more risks. It is time for them to have the means to protect themselves against HIV infections, other sexually transmitted diseases (STDs), and unwanted pregnancy. More than 50% of the world's population is less than 25 years old. Youth are becoming sexually active at younger ages. More than 50% of HIV cases in the world are younger than 25. The most vulnerable to HIV are young women. When young adults die of AIDS, their children become orphans and must live with other family members. Most deaths among 15-19 year old girls are associated with pregnancy or childbirth. 1 in 20 adolescents has been treated for at least 1 STD. The number is probably higher since most youth do not have access to STD treatment or do not even know they have an STD. Youth often do not have access to sexuality counseling, family planning services, or STD services. Adolescence is a time of considerable physical and emotional change. Youth want to experience new ways to love and to feel loved. These new experiences and the risks that come with the experiences are needed for development but youth need support to avoid risky behavior. Factors that make the already vulnerable youth even more vulnerable are poverty, unemployment, little education, abuse of alcohol and drugs, and violence. Youth need sex education at school; activities in religious, sport, and youth club organizations; use of the mass media to promote sexual responsibility; and access to family planning. Youth programs must be based on specific responses and beliefs, information, and knowledge needs identified by the youth themselves. Youth need more than facts on sex and reproduction. They need to discuss, ask

  13. Do Young Children Modulate Their Cognitive Control?

    2016-03-01

    Dynamic, trial-by-trial modulations of inhibitory control are well documented in adults but rarely investigated in children. Here, we examined whether 5-to-7 year-old children, an age range when inhibitory control is still partially immature, achieve such modulations. Fifty three children took flanker, Simon, and Stroop tasks. Above and beyond classic congruency effects, the present results showed two crucial findings. First, we found evidence for sequential modulations of congruency effects in these young children in the three conflict tasks. Second, our results showed both task specificities and task commonalities. These findings in young children have important implications as they suggest that, to be modulated, inhibitory control does not require full maturation and that the precise pattern of trial-by-trial modulations may depend on the nature of conflict.

  14. Understanding Young Exoplanet Analogs with WISE

    Science.gov (United States)

    Rice, Emily

    , the results of our work will improve our understanding of objects at the intersection of stars and planets and be directly applicable to understanding the atmospheres of directly-imaged exoplanets. The assembled investigators are the absolute best team to accomplish this work. They have extensive and diverse observational experience in astrometry, photometry, and spectroscopy from the optical through the mid-IR, spanning nearly the entire spectral energy distribution of young brown dwarfs and encompassing their most fundamental observational properties. They have considerable experience mining large photometric catalogs and identifying low-gravity very low mass objects. The team maintains collaborations with two groups actively modelling brown dwarf and exoplanet atmospheres and interior evolution. The proposed research organically combines several ongoing projects into a cohesive program that will efficiently incorporate WISE data to disentangle the ambiguous and interdependent physical properties of young brown dwarfs. As a result of the team's previous observational projects, we have assembled a dataset that positions us to best interpret WISE observations brown dwarfs and identify new young brown dwarfs in the WISE archive. A significant parallax program is ongoing, and all of the computing resources and many of the analysis tools are already in place, including several well-tested pipelines for data reduction and analysis and model comparisons. The team will incorporate undergraduate students in the project through an existing NSF-funded REU program.

  15. MAGMADIM: Young Explainers Program

    International Nuclear Information System (INIS)

    Full Text:Physics teachers and educators constantly face the problem of inspiring their students to major in physics. On the other hand, science museums are designed to provide a pleasant environment which will stimulate and encourage a science associated experience to the general public. Typically, there is no intention to teach science as such in science museums. One may, however, use the science museum to teach and inspire certain groups of students in a much deeper sense. In fact they may actually enthusiastically learn much of the school physics curriculum at the museum. This report discusses the Magmadim program through which 10th graders are trained to be young explainers at the Weizmann Institutes Clore Garden of Science. To this end they study the physics underlying its exhibits in an after-school course. The ultimate goal is for the 'magmadim' to become the best possible explainers and be able to face all sorts of museum visitors. Along with learning how to instruct visitors, they must learn the physics behind the exhibits to give a full explanation of the exhibit and be able to answer any question that may arise. Our 5 year experience with the program shows that its self-selected participants not only study a lot of science, but also like it and learn how to explain the content to other people. This program, along with similar programs at the Bloomfield Science Museum and the Madatzim (young physics tutors) program of Ort, help in promoting the interest in science in general and physics in particular among school students. Various ways to expand the programs will also be discussed

    The definition of the age of young offenders was changed by an Act of Parliament (The Crime and Disorder Act 1998), which was implemented by the Home Office on 1 April 2000. This Act brought down the upper-age limit of young offenders from 20 to 17. Our objective was to investigate the sexually transmitted infections (STIs) among this redefined group of young offenders. Among various types of STIs, we observed that a significant number of young prisoners had complaints of testicular lumps (35%), which were not reported in the past. We tried to find out the reason for this common complaint and believe that this was due to extra vigilance, and testicular self-examination in conjunction with sex and relationship programmes which ran alongside other programmes developed as a joint venture by Prisoner Learning and Skills Unit, Prison Health Policy Unit and Sex Education Forum.

  3. ENERGY REGULATION IN YOUNG PEOPLE

    2007-09-01

    Full Text Available Obesity in young people is now realised as a worldwide crisis of epidemic proportion. The aetiology of this disease suggests a disruption in regulation of energy at the population level, leading to a positive energy balance and excess adiposity. The relative contribution of food intake and physical inactivity remains to be elucidated. Treatment interventions have aimed to create a deficit in energy balance through manipulation of physical activity, behavioural components or, to a lesser extent, dietary modification. Whether such intervention is maintained in the long-term is as yet unclear, however it seems a combination of therapies is optimal. Mindful of a mismatch between energy intake and expenditure, recent work has begun to examine the acute relationship between physical activity and food intake in children. Initial findings suggest a short-term delay in compensation through energy intake for exercise- induced energy expenditure. The overarching study of energy regulation in children and adolescents is clearly multifaceted in nature and variables to be assessed or manipulated require careful consideration. The collection of paediatric physical activity, energy expenditure and food intake data is a time-consuming process, fraught with potential sources of error. Investigators should consider the validity and reliability of these and other issues, alongside the logistics of any proposed study. Despite these areas of concern, recent advances in the field should provide exciting opportunities for future research in paediatric energy regulation on a variety of levels

Experts are concerned of the emerging stroke epidemic in India. Stroke affecting the young has potentially devastating consequence son the individual and his family. Certain risk factors are unique to the young. I t needs more studies for identification and modification of risk factors. The study aims to evaluate clinical features, risk factors, etiology and mortality of stroke in young patients. METHODS : 74 young patients satisfying the inclusion criteria were included in this study. A detailed history was taken from young stroke patients, systemic examination and required investigations were done. Data was collected in standardized proforma and analysed. RESULTS: Stroke in young accounts for 7.95% of stroke cases of all age groups. The mean age of the patients was 34.66 ± 7.48 years. Among 74 patients, 47(63.51% were male and 27(36.49% were female. Seizures, decreased consciousness, speech involvement and motor deficit were observed in 33.78%, 44.59%, 22.97% and 100% of cases respectively. 82.43% patients had ischemic and 17.57% patients had hemorrhagic stroke. Among ischemic stroke, large artery atherosclerosis was 16.21%, tuberculous meningoencephalitis with vasculitis was 16.21%, lacunar stroke was 10.81%, CVT was 10.81% and cardio embolic stroke was 6.76%.

    The role of the Vietnam Youth Union (21 million members) is to educate the youth aged 14-28 years about the movement at the grassroots level. Since 1995, it has been entrusted with information, education, and communication (IEC) activities (implemented through the Educational Center for Population, Health, and Development) concerning family planning, the environment, human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS). Mass media, direct communication, Youth Union leading staff, Youth Union cultural and arts activities, and advertisement have been used. 16 newspapers and magazines, a radio program, and a TV program disseminate information for the group. 1000 motivators' groups, 1370 Youth Clubs, and Youth Villages at the commune level work to enhance awareness and to change biased attitudes and habits. Leading staff speak at conferences and seminars that are attended by target groups. Art troupes perform at special local events; plays are organized and videos are shown. The HIV/AIDS information and prevention campaign is of great importance because research findings indicate that many young people believe that only prostitutes and drug addicts can be infected, and that condoms are bad and only for use with prostitutes. There are about 2300 persons infected with HIV in 14 provinces, mostly in the south and central regions. 131 are reported to have developed AIDS. PMID:12320323

    Full Text Available The aim of this study was to examine the relationship between motivational characteristics and dispositional flow. In order to accomplish this goal, motivational profiles emerging from key constructs within Achievement Goal Theory and Self-Determination Theory were related to the dispositional flow measures. A sample of 413 young athletes (Age range 12 to 16 years completed the PMCSQ-2, POSQ, SMS and DFS measures. Cluster analysis results revealed three profiles: a "self-determined profile" characterised by higher scores on the task-involving climate perception and on the task orientation; a "non-self-determined profile", characterised by higher scores on ego-involving climate perception and ego orientation; and a "low self-determined and low non-self-determined profile" which had the lowest dispositional flow. No meaningful differences were found between the "self-determined profile" and the "non-self-determined profile" in dispositional flow. The "self-determined profile" was more commonly associated with females, athletes practising individual sports and those training more than three days a week. The "non-self-determined profile" was more customary of males and athletes practising team sports as well as those training just two or three days a week

  7. Young onset dementia.

    2016-07-01

    Young onset dementia (YOD), where symptoms of dementia have an onset before the age of 65, has become more prominent due to the population increase from the Baby Boomer generation. This clinical perspective examines key issues in the assessment, diagnosis and management of YOD. Challenges in the assessment and diagnosis of YOD are partly due to the diverse range of types of YOD, where degenerative dementias are less common and secondary dementias more common than in late onset dementia. Early symptoms are broad and include depression, behavioural change, neurological disorders, systemic disorders and mild cognitive impairment (MCI). Perceived diagnostic delay may result in frustration and distress in people with YOD and their families. Chronic depression and MCI are associated with longer time to diagnosis, and in these situations, clinicians need to establish appropriate review processes and communicate clearly. A diagnosis of YOD may have marked consequences for a younger person, including early retirement, financial impacts and the psychological challenge of coming to grips with cognitive decline. Partners, children and other supporters often have unmet needs, feel burdened by care and are at high risk of physical and emotional consequences. Concerns about the heritability of dementia may add to family distress. Recent community service developments in Australia for YOD are outlined and the challenges of residential care described.

    Full Text Available In the article the results of a research carried out in 2005 on the sample of 134 respondents are presented. The results of the research indicate that young consumers are very active on the food market. Teenagers derive their knowledge about nutrition mainly from their family home but also from school as well as from books and literature publica-tions. Together with age the range of participation of grammar school teenagers in family shopping has declined, while their role and activeness of individual purchaser has risen. Families were commonly shopping mainly in small near-home shops and also, but less frequently, in hyper- and supermarkets. Teenagers were shopping individually mainly in small near home shops and school shops spending on average 9 PLN per week. While choosing the shopping place grammar school teenagers took under consideration mainly the price level and the quality of goods offered. The most important factors taken into consideration by the tested teenagers while buying food individually were: the freshness, the taste and the brand. Teenagers were engaged in decisive process of purchasing food for the family household mainly as far as products which were meant for them as con-sumers. Products such as beverages, chips, sweets and ice-creams were the main items of their individual purchase. Basing on the results of the survey a rather positive attitude of the tested teenagers was noticed towards promotion of sales. They were also more prone to impulsive purchase and more than averagely prone to novelties.

    2009-02-01

    Using optimized voxel-based morphometry (VBM), this study systematically investigated the differences and similarities of brain structural changes during the early three developmental periods of human lives: childhood, adolescence and young adulthood. These brain changes were discussed in relationship to the corresponding cognitive function development during these three periods. Magnetic Resonance Imaging (MRI) data from 158 Chinese healthy children, adolescents and young adults, aged 7.26 to 22.80 years old, were included in this study. Using the customized brain template together with the gray matter/white matter/cerebrospinal fluid prior probability maps, we found that there were more age-related positive changes in the frontal lobe, less in hippocampus and amygdala during childhood, but more in bilateral hippocampus and amygdala and left fusiform gyrus during adolescence and young adulthood. There were more age-related negative changes near to central sulcus during childhood, but these changes extended to the frontal and parietal lobes, mainly in the parietal lobe, during adolescence and young adulthood, and more in the prefrontal lobe during young adulthood. So gray matter volume in the parietal lobe significantly decreased from childhood and continued to decrease till young adulthood. These findings may aid in understanding the age-related differences in cognitive function.

    This study prospectively investigates associations between youth moderate-to-vigorous-intensity physical activity (MVPA) and body composition in young adult women using data from the Dietary Intervention Study in Children (DISC) and the DISC06 Follow-Up Study. MVPA was assessed by questionnaire on 5 occasions between the ages 8 and 18 years and at age 25-29 years in 215 DISC female participants. Using whole body dual-energy x-ray absorptiometry (DXA), overall adiposity and body fat distribution were assessed at age 25-29 years by percent body fat (%fat) and android-to-gynoid (A:G) fat ratio, respectively. Linear mixed effects models and generalized linear latent and mixed models were used to assess associations of youth MVPA with both outcomes. Young adult MVPA, adjusted for other young adult characteristics, was significantly inversely associated with young adult %fat (%fat decreased from 37.4% in the lowest MVPA quartile to 32.8% in the highest (p-trend = 0.02)). Adjusted for youth and young adult characteristics including young adult MVPA, youth MVPA also was significantly inversely associated with young adult %fat (β=-0.40 per 10 MET-hrs/wk, p = .02) . No significant associations between MVPA and A:G fat ratio were observed. Results suggest that youth and young adult MVPA are important independent predictors of adiposity in young women.

  12. Faint young Sun paradox remains

    CERN Document Server

    Goldlatt, Colin

    2011-01-01

    The Sun was fainter when the Earth was young, but the climate was generally at least as warm as today; this is known as the `faint young Sun paradox'. Rosing et al. [1] claim that the paradox can be resolved by making the early Earth's clouds and surface less reflective. We show that, even with the strongest plausible assumptions, reducing cloud and surface albedos falls short by a factor of two of resolving the paradox. A temperate Archean climate cannot be reconciled with the low level of CO2 suggested by Rosing et al. [1]; a stronger greenhouse effect is needed.

    2016-06-01

    The survival gap between adolescents and young adults (AYAs) with hematological malignancies persists in many countries. To determine to what extent it does in Japan, we investigated survival and treatment regimens in 211 Japanese AYAs (15-29 years) in the Osaka Cancer Registry diagnosed during 2001-2005 with hematological malignancies, and compared adolescents (15-19 years) with young adults (20-29 years). AYAs with acute lymphoblastic leukemia (ALL) had a poor 5-year survival (44%), particularly young adults (29% vs. 64% in adolescents, p = 0.01). Additional investigation for patients with ALL revealed that only 19% of young adults were treated with pediatric treatment regimens compared with 45% of adolescents (p = 0.05). Our data indicate that we need to focus on young adults with ALL and to consider establishing appropriate cancer care system and guidelines for them in Japan. PMID:26695739

    Rabin, Carolyn; Horowitz, Santina; Marcus, Bess

    2013-03-01

    Young adults have been dramatically underrepresented in cancer survivorship research. One contributing factor is the difficulty recruiting this population. To identify effective recruitment strategies, the current study assessed the yield of strategies used to recruit young survivors for an exercise intervention including: clinic-based recruitment, recruitment at cancer-related events, mailings, telephone-based recruitment, advertising on the internet, radio, television and social networking media, distributing brochures and word-of-mouth referrals. When taking into account the strategies for which we could track the number of survivors approached, recruitment at an oncology clinic was the most productive: 38 % of those approached were screened and 8 % enrolled. When evaluating which strategy yielded the greatest percentage of the sample, however, mailings were the most productive. Given widespread use of the internet and social networking by young adults, investigators should also consider these low-cost recruitment strategies. PMID:22810954

    Full Text Available While involved in organising an empowerment seminar for the Igbo rural youths, the authors investigated resilience among rural adolescents and young adults. Three hundred and twenty nine (329 adolescents (n = 162 and young adults (n = 167, comprising 159 males and 170 females, were participants. They completed the 14-item Resilience scale and provided some relevant demographic information. Analysis Of Variance (ANOVA was used to test for differences in resilience on account of age, gender and level of education. Young adults had significantly higher resilience scores than adolescents. No significant difference was found in resilience scores of males and females. Participants with higher education had significantly higher resilience scores than those with lower education. Of all the interaction effects tested, only age * gender * education had a significant interaction effect on resilience. Discussion of the findings were based on the literature, realities of life in contemporary Igbo society and the authors’ observations.

  3. Young Indonesian Cruise Workers, Symbolic Violence and International Class Relations

    Directory of Open Access Journals (Sweden)

    Luh Putu Artini

    2011-05-01

    Full Text Available This article reports on an investigation of the experiences of well-educated young Indonesians who choose a career in cruise ship work rather than go to university, or work in the local tourist industry. A sociological approach is taken that sees the cruise ship environment as a microcosm of international class relations. Attention is paid to the symbolic violence experienced by young workers who find their dream of travel on the high seas consists of mundane service work in uncomfortable conditions far from home. The phenomenon suggests the emergence of a young cosmopolitan migrant worker who does not experience any acculturation to a new country, but acculturation to life in a “total environment” of 24 hour service work subject to few international labor regulations. Undoubtedly there are financial and work experience benefits, but there is also much to be endured in the extended transition from youth to adulthood during cruise ship work.

    Objectives Lack of work-participation and early disability pensions (DP's) among young adults are increasing public health problems in most western European countries. The present study investigated determinants of early DP in young adults in vocational rehabilitation. Methods Data from 928 young adults (aged 18-40 years) attending a vocational rehabilitation program was linked to DP's recorded in the Norwegian Labor and Welfare Organization registries (1992-2010) and later compared to a group of 65 employees (workers). We used logistic regression to estimate the odds ratio for entitlement to DP following rehabilitation, adjusting for socio-demographical, psychosocial and health-behavior factors. Results Significant differences in socio-demographical, psychosocial and health-behavior factors were found between the rehabilitation group and workers. A total of 60 individuals (6.5 %) were granted a DP during follow-up. Increase in age, teenage parenthood, single status, as well as low education level and not being employed were found to be the strongest independent determinants of DP. Conclusion Poor social relations (being lone), early childbearing and weak connection to working life contributed to increase in risk of DP's among young adults in vocational rehabilitation, also after adjusting for education level. These findings are important in the prevention of early disability retirements among young adults and should be considered in the development of targeted interventions aimed at individuals particularly at risk of not being integrated into future work lives.

  6. INVESTIGATING EFFECTS OF INTRODUCTION OF CORNCOB ASH INTO PORTLAND CEMENTS CONCRETE: MECHANICAL AND THERMAL PROPERTIES

    Directory of Open Access Journals (Sweden)

    Antonio Price

    2014-01-01

    Full Text Available The purpose of this study was to evaluate the benefits of replacing Ordinary Portland Cement (OPC with Corncob Ash (CCA blended cements. The cement industry contributes considerable amount of Carbon Dioxide (CO2 emissions into the atmosphere. The main contribution of CO2 emissions from cement production results from the process of creating Calcium Oxide (CaO from limestone (CaCO3 commonly known as the calcination process. Blending OPC with a pozzolanic material will assist in the reduction of CO2 emissions due to calcination as well as enhance the quality of OPC. There are various pozzolanic materials such as fly ash, rice husk, silica fume and CCA that could be promising partial replacement for OPC. In this study, CCA will serve as the primary blending agent with OPC. An experiment was performed to designate an appropriate percentage replacement of CCA that would comply with specific standards of cement production. The experimental plan was designed to analyze compressive strength, workability and thermal performance of various CCA blended cements. The data from the experiment indicates that up to 10% CCA replacement could be used in cement production without compromising the structural integrity of OPC. In addition, it was found that the compressive strength and workability of the resulting concrete could be improved when CCA is added to the mixtures. Furthermore, it was shown that the introduction of 10% CCA can lead to significant reduction in thermal conductivity of the mixture.

    It is unclear whom animals select to huddle with for thermoregulation. In this study, we investigated whom Japanese macaque (Macaca fuscata) mothers huddled with-their young offspring or other adult group members-when there is need for thermoregulation. We used a focal-animal sampling method, targeting 17 females at Katsuyama, Okayama Prefecture, Japan. A majority of huddling among adult females was recorded during winter season (December, January, and February). Females who had young (0- or 1-year-old) offspring huddled less frequently with other adult females compared to females who did not have young offspring in winter. However, including young offspring, the frequency of huddling with any other individuals did not differ by whether females had young offspring. Moreover, the females who did not have young offspring huddled with other adult females more often in cloudy than in sunny weather during winter season. In contrast, females who had young offspring increased huddling with their young offspring in cloudy than in sunny weather, but did not do so with other adult females. This study indicates that Japanese macaque mothers huddle with their young offspring instead of other adult females when there is need for thermoregulation. PMID:27262980

  8. The Dispersed Young Population in Orion

    CERN Document Server

    Briceno, Cesar

    2008-01-01

    The Orion OB1 Association, at a distance of roughly 400 pc and spanning over ~200 deg^2 on the sky, is one of the largest and nearest OB associations. With a wide range of ages and environmental conditions, Orion is an ideal laboratory for investigating fundamental questions related to the birth of stars and planetary systems. This rich region exhibits all stages of the star formation process, from very young, embedded clusters, to older, fully exposed young stars; it also harbors dense clusters and widely spread populations in vast, low stellar density areas. This review focuses on the later, namely, the low-mass (M ~< 2 Mo), pre-main sequence population spread over wide spatial scales in Orion OB1, mostly in the off-cloud areas. As ongoing studies yield more complete censa it becomes clearer that this "distributed" or non-clustered population, is as numerous as that located in the molecular clouds; modern studies of star formation in Orion would be incomplete if they did not include this widely spread po...

  9. Fertility preservation in young patients with cancer

    2015-01-01

    Full Text Available Infertility can arise as a consequence of treatment of oncological conditions. The parallel and continued improvement in both the management of oncology and fertility cases in recent times has brought to the forefront the potential for fertility preservation in patients being treated for cancer. Many survivors will maintain their reproductive potential after the successful completion of treatment for cancer. However total body irradiation, radiation to the gonads, and certain high dose chemotherapy regimens can place women at risk for acute ovarian failure or premature menopause and men at risk for temporary or permanent azoospermia. Providing information about risk of infertility and possible interventions to maintain reproductive potential are critical for the adolescent and young adult population at the time of diagnosis. There are established means of preserving fertility before cancer treatment; specifically, sperm cryopreservation for men and in vitro fertilization and embryo cryopreservation for women. Several innovative techniques are being actively investigated, including oocyte and ovarian follicle cryopreservation, ovarian tissue transplantation, and in vitro follicle maturation, which may expand the number of fertility preservation choices for young cancer patients. Fertility preservation may also require some modification of cancer therapy; thus, patients' wishes regarding future fertility and available fertility preservation alternatives should be discussed before initiation of therapy.

    The Selberg integral is an important integral first evaluated by Selberg in 1944. Stanley found a combinatorial interpretation of the Selberg integral in terms of permutations. In this paper, new combinatorial objects "Young books" are introduced and shown to have a connection with the Selberg integral. This connection gives an enumeration formula for Young books. It is shown that special cases of Young books become standard Young tableaux of various shapes: shifted staircases, squares, certa...

  13. Young and Waltzing Binary Stars

    2001-10-01

    stars heat up enough to start nuclear burning. When infant stars in RXJ 0529.4+0041 eventually reach middle-age, their sizes will most likely also be quite similar to that of the Sun. The significance of RXJ 0529.4+0041 Few systems are known for which such precise determinations of the stellar parameters have ever been possible - and this binary system represents the first case where both the components are such young stars . A detailed comparison of the derived stellar parameters with current models for the evolution of young stars shows fairly good agreement for the primary component. However, there are certain discrepancies in the case of the secondary component, showing that the current models for the early stages of lower-mass stars must still be refined. More information Part of the results described in this press release are described in more detail in a scientific article ( "RXJ 0529.4+0041: a low-mass pre-main sequence eclipsing-spectroscopic binary" by E. Covino et al.) that has been published in the European research journal Astronomy & Astrophysics (Vol. 361, p. 49). Notes [1] The team consists of Elvira Covino (Principal Investigator), Juan M. Alcalá , Rosita Paladino (all Osservatorio Astronomico di Capodimonte, Napoli, Italy), Antonio Frasca , Santo Catalano , Ettore Marilli (all Osservatorio Astrofisico di Catania, Italy) and Michael Sterzik (ESO-Chile). [2] One solar mass corresponds to 1.99 10 30 kg, or about 330,000 times the mass of the Earth. The Sun is about 4500 million years old and its total lifetime is of the order of 12-13,000 million years. It is an interesting thought that if the Sun would have been somewhat heavier, its total lifetime might have been too short for living organisms to develop on the Earth. In fact, the biological evolution that ultimately lead to the emergence of human beings apparently lasted about 4 billion years; this corresponds to the total lifetime of a star that is only about 20 % heavier than the Sun.

  20. New morbidity of the young

    Directory of Open Access Journals (Sweden)

    Stanković Biljana

    2002-01-01

    Full Text Available In the present phase of epidemiological transition, the most frequent causes of youth morbidity are disorders in reproductive health, mental disorders and injuries which are not life threatening. This, so-called new youth morbidity, is most often caused by their risky behavior, which in the field of sexuality often leads to unplanned pregnancies and abortions, as well as sexually transmitted infections. Misuse of tobacco, alcohol and narcotics, which is most commonly started in adolescence, has an unfavorable short-term and long-term influence on the psycho-physical health of the young. All research, in the world and in our country, indicate gradual yet constant growth of sexual activity of the youth and the age decrease of its starting point, especially when girls are in question. Due to insufficient maturity and inadequate knowledge and consciousness on the necessity of protecting reproductive health, sexual behavior of young people can often be characterized as insufficiently responsible and not supplemented with the usage of adequate protective measures. The result is frequently abortion, which terminates 90% of unplanned and unwanted pregnancies in this age. This creates health and psychosocial risks, as well as giving birth in adolescence which is contrary to the modern health concepts that giving birth should not be performed too early, while the young are still developing. A significant increase in the frequency of sexually transmitted diseases is also present, to which the youth are especially susceptible due to the specific development period in which they are in. A serious medical and sociopathological problem of contemporary society represents the greater and greater misuse of psychoactive substances among the young people, with a tendency of decreasing the average age they are consumed for the first time, as well as the use of drugs and alcohol. With the increase of the anti-smoking campaign and restrictive measures in highly

    Full Text Available Lebanon is a small democratic country with a population of less than four million and a range of diversity; there are at least 18 different religious sects and 19 different political parties. The diversity among ethnic, religious and/or political groups has created conflicts that severely impact the Lebanese economy, environment, politics and most importance our young citizens. The aim of this investigation is to capture students’ awareness and attitudes toward the accountability and mechanisms of peace and democracy. Data for the study was obtained from extensive literature reviews and questionnaire surveys of 70 high school students. The investigation was conducted in the fall of the year 2013. The results of the study showed that most Lebanese young citizen view peace and democracy process associated with the end of violence and conflict behaviors; very small percent of respondents believe that bringing peace and democracy process should be answered by the people or by themselves. Results also indicate a lack of a sense of security among young citizen. This raises the urgent need to put into practice an effective peace education program that inspires and motivates young citizens to be involved in the peace and the democracy building process.

  3. Interactions between exoplanets and the winds of young stars

    Directory of Open Access Journals (Sweden)

    Vidotto A. A.

    2014-01-01

    Full Text Available The topology of the magnetic field of young stars is important not only for the investigation of magnetospheric accretion, but also responsible in shaping the large-scale structure of stellar winds, which are crucial for regulating the rotation evolution of stars. Because winds of young stars are believed to have enhanced mass-loss rates compared to those of cool, main-sequence stars, the interaction of winds with newborn exoplanets might affect the early evolution of planetary systems. This interaction can also give rise to observational signatures which could be used as a way to detect young planets, while simultaneously probing for the presence of their still elusive magnetic fields. Here, we investigate the interaction between winds of young stars and hypothetical planets. For that, we model the stellar winds by means of 3D numerical magnetohydrodynamic simulations. Although these models adopt simplified topologies of the stellar magnetic field (dipolar fields that are misaligned with the rotation axis of the star, we show that asymmetric field topologies can lead to an enhancement of the stellar wind power, resulting not only in an enhancement of angular momentum losses, but also intensifying and rotationally modulating the wind interactions with exoplanets.

  4. Giant adrenal incidentaloma in young patient

    International Nuclear Information System (INIS)

    Incidental adrenal tumors are lesions occasionally observed during abdominal US or CT scans. These tumors have been observed in patients without clinical or laboratorial signs of adrenal disease. The authors report a case of a 18 - years - old young man who was admitted to the Franco da Rocha Hospital, Sao Paulo, with abdominal pain and a palpated mass in the epigastrium which began one month ago. These findings were preceded by a blunt trauma at the epigastrium three months earlier. First clinical hypothesis was of a traumatic pancreatic pseudocyst. However, investigation and laparotomy showed a large left adrenal solid mass, weighting 700 g. The mass was removed and histology was performed. There was no evidence of malignant neoplasm, then the diagnostic of incidental adenoma of adrenal was confirmed. The authors hope to stimulate surgeons for early detection of these lesions in order to prevent the complications and improve the prognosis. (author)

    We demonstrate a polymer slot waveguide Young interferometer coated with a bilayer of Al2O3/TiO2. The approach enables relaxed dimensions of the polymer waveguide which simplifies the fabrication of the structure with a resolution of 50 nm. The layers were coated by an atomic layer deposition technique. The feasibility of the device was investigated by exploiting the interferometric structure as a bulk refractive index sensor operating at 975 nm wavelength for detection of an ethanol-water solution. A refractive index change of 1 × 10-6 RIU with a sensing length of only 800 µm was detected. The approach confirms the possibility of realizing a low cost device with a small footprint and enhanced sensitivity by employing the TiO2 rails in the sides of the slot waveguide. PMID:27409852

  17. The faint young Sun problem

    CERN Document Server

    Feulner, Georg

    2012-01-01

    For more than four decades, scientists have been trying to find an answer to one of the most fundamental questions in paleoclimatology, the `faint young Sun problem'. For the early Earth, models of stellar evolution predict a solar energy input to the climate system which is about 25% lower than today. This would result in a completely frozen world over the first two billion years in the history of our planet, if all other parameters controlling Earth's climate had been the same. Yet there is ample evidence for the presence of liquid surface water and even life in the Archean (3.8 to 2.5 billion years before present), so some effect (or effects) must have been compensating for the faint young Sun. A wide range of possible solutions have been suggested and explored during the last four decades, with most studies focusing on higher concentrations of atmospheric greenhouse gases like carbon dioxide, methane or ammonia. All of these solutions present considerable difficulties, however, so the faint young Sun prob...

  18. Young's modulus of nanoconfined liquids?

    Khan, Shah Haidar; Hoffmann, Peter Manfred

    2016-07-01

    In material science, bioengineering, and biology, thin liquid films and soft matter membranes play an important role in micro-lubrication, ion transport, and fundamental biological processes. Various attempts have been made to characterize the elastic properties, such as Young's modulus, of such films using Hertz theory by incorporating convoluted mathematical corrections. We propose a simple way to extract tip-size independent elastic properties based on stiffness and force measurement through a spherical tip on a flat surface. Using our model, the Young's modulus of nanoconfined, molecularly-thin, layers of a model liquid TEHOS (tetrakis 2-ethylhexoxy silane) and water were determined using a small-amplitude AFM. This AFM can simultaneously measure the stiffness and forces of nanoscale films. While the stiffness scales linearly with the tip radius, the measured Young's modulus essentially remains constant over an order of magnitude variation in the tip radius. The values obtained for the elastic modulus of TEHOS and water films on the basis of our method are significantly lower than the confining surfaces' elastic moduli, in contrast with the uncorrected Hertz model, suggesting that our method can serve as a simple way to compare elastic properties of nanoscale thin films as well as to characterize a variety of soft films. In addition, our results show that the elastic properties (elastic modulus) of nanoconfined liquid films remain fairly independent of increasing confinement. PMID:27060229

  19. Keeping a learned society young

    Directory of Open Access Journals (Sweden)

    Herbert Dawid

    2009-05-01

    Full Text Available Aging organizations - regardless of whether they are firms, faculties, societies, political bodies, teams, or national academies - seek ways to rejuvenate. This paper demonstrates that the best way to keep an organization young is through a mixed strategy of recruiting both young and old, and that, contrary to intuition, recruiting those of middle age is the least effective strategy for maintaining a younger age structure. The aging of learned societies is a problem in many national academies. Faced with rising life expectancy, particularly for older persons, the average age of academy members is increasing. Another reason for "overaging" is an increase in the age at election. In an organization with a fixed size, the annual intake is strictly determined by the number of deaths and the statutory retirement age. This can, among many learned societies, lead to a fundamental dilemma: the desire to maintain a young age structure, while still guaranteeing a high recruitment rate. We derive an optimal recruitment policy which is bimodal, i.e., it entails shifting recruitment partly to younger ages and partly to older ages, while decreasing the recruitment of middle-aged candidates. Although the optimization problem explicitly involves only the average age and the recruitment rate as objectives, the methodology implicitly allows us to take into consideration all other objectives (formal or informal used in the actual election practice.

    2016-03-01

    Despite the rapid growth of the gambling industry over the last 40 years, there have been few large-scale, nationally representative longitudinal studies of gambling among young adults. We use data from the National Longitudinal Study of Adolescent to Adult Health to investigate whether and how the gambling behavior of young adults is associated with their religious beliefs and practices during adolescence. We find that young adults who grew up as conservative Protestants, mainline Protestants, Mormons, and Jehovah's Witnesses; those were raised in a community with a higher percentage of conservative Protestants; and those who attended religious services weekly are less likely to have ever gambled. Among gamblers, young adults who attended religious services up to three times per month as adolescents are more likely to experience gambling problems than those who never attend. Notably, accounting for a young adult's propensity for risk-taking behavior does not explain the associations between religion and gambling. PMID:25722077

  17. Young physicians' competences from different points of view.

    Schober, Barbara; Spiel, Christiane; Reimann, Ralph

    2004-08-01

    This paper describes a baseline evaluation of medical education focusing on the competences of young physicians. It was conducted in the context of a reform mandated for medical programs at Austrian state universities. The study investigated the goals of medical education (ideal situation) as well as the real situation. Furthermore, learning methods used by medical students were analyzed. A multiple-perspective procedure was applied and questionnaire data from students, graduates, university teachers, and clinical supervisors of young graduates were collected at the University of Graz. A high discrepancy was found between the goals of medical teaching and the educational effectiveness of achieving them. Competences of young physicians were rated to be relatively low -- thereby external ratings were systematically lower than self-ratings by students and graduates. Reading passages from required textbooks is the dominant learning behavior among students. Based on the results, a gap between the ideal and the actual medical competences imparted at university can be identified. With regard to the generally low-rated competences of young physicians, the precondition for practical requirements hardly seems to be optimal. PMID:15369886

  18. SELF-ASSESSMENT AMONG YOUNG LEARNERS OF ENGLISH

    Directory of Open Access Journals (Sweden)

    Arni Sukmiarni

    2015-12-01

    Full Text Available The implementation of self-assessment among young learners becomes a challenging issue to include in English classroom assessment. The common belief that children cannot self-assess accurately as adults do seems to yield that the inclusion of self-assessment in TEYL is still not prevalent yet. Self-assessment is an assessment involving the ability in assessing one’s own performance in learning. This is strongly related to one’s metacognition development. The tendency of earlier research investigating metacognitive capacities of young children concludes that mecognition in children is a late developing skill (Lai, 2011. In fact, more recent empirical studies conclude that young children have capability of simple metacognition thought (Lai, 2011. Hence, the inclusion of self-assessment in TEYL can be implemented as an assessment supporting other assessment conducted in classroom. Self-assessment is beneficial in improving students’s own awareness of their learning progress. In Indonesian context, English as a foreign language, has been taught in elementary school since 1994 and generally formative and summative assessments as classroom assessments are employed to assess student’s progress in learning. Self-assessment is an assessment that needs to be considered to include in classroom assessment. This paper discusses self-assessment among young learners, in this context elementary school students studying English.

    Dental caries is caused by a combination of infection and diet. This disease, if left untreated, may lead to pain, and impair the quality of life, nutritional status and development of young children. The objective was to investigate the association between snacking and caries in a population at high risk of dental caries. American preschool children (n = 1,206) were recruited in the offices of paediatricians. Data on sociodemographic characteristics, oral hygiene, breast-feeding, use of bottle and snacking were collected by questionnaire. Plaque presence, the number of teeth and their caries status (deft) were scored. The children sampled were 61% Black, 27% White and 10% Asian. Of the 1- to 2-, 2- to 3- and 3- to 4-year-old children, 93.8, 82.4 and 77.3% were caries free, and their mean caries scores were 0.16, 0.58 and 0.93, respectively. Multivariate partial least squares (PLS) modelling revealed plaque presence, lowest income, descriptors for tooth exposure time (number of teeth and age) and cariogenic challenge (total intake of sugar-containing snacks and chips/crisps, and chips intake with a sugar-containing drink) to be associated with more caries. These differences were also found in univariate analyses; in addition, children who continued breast-feeding after falling asleep had significantly higher deft values than those who did not. PLS modelling revealed that eating chips clustered with eating many sweet snacks, candies, popcorn and ice cream. We conclude that, in addition to the traditional risk indicators for caries - presence of plaque, sugar intake and socioeconomic status -, consumption of chips was associated with caries in young children.

  16. ROMANIAN YOUNG ENTREPRENEURS FEATURES: AN EMPIRICAL SURVEY

    Directory of Open Access Journals (Sweden)

    Ceptureanu Sebastian Ion

    2015-07-01

    Full Text Available There are many studies linking entrepreneurship and economic development. For specialists and public decision makers, developing entrepreneurship seems to be an easy policy action, even though actions and results are rather debatable. Unfortunately the relevant literature is not so generous concerning youth entrepreneurship. Youth is one of the most vulnerable groups in society, especially in the current economic and demographic situation in European Union and worldwide. At the same time, youth is the period when most people engage in their first job, are gaining financial independence and are assuming new responsibilities and roles shaping their identity. With respect to this, starting their own business is a natural choice for many young people. When considering entrepreneurial potential of young Romanians, there is almost not any data available. This paper aims to disseminate the results of a survey focused on young entrepreneurs, designed to fill the gap in the literature about Romanian young entrepreneurs’ features. The empirical study was divided in five parts: A. Personality of young entrepreneurs, highlighting the main features of behaviour and personality of young entrepreneurs. B. Professional background, focusing on young entrepreneurs’ background and how it influences their interest and performance improvement. C. Risk and crisis acceptance, highlighting the ability of young entrepreneurs to deal with critical situations. D. Business and business environment, focusing on internal and environmental aspects of the business. E. Social - cultural attitude, highlighting the attitude of society (incentives and disincentives to entrepreneurial initiatives of young people. This are excerpts of results from the first part, regarding personality of Romanian young entrepreneurs, concerning issues like level of independence, capacity for innovation, self-confidence, decision making process, level of persistence flexibility of young

    Curcuminoids content in Curcuma longa L. rhizome from seven locations, which are Chongzhou and Qianwei of Sichuan, Sihui of Guangdong, Yulin, Bobai and Jinxiu of Guangxi, Maguan of Yunnan, was determined by HPLC. And correlation of curcuminoids content in C. longa rhizome from different locations with geography-climate factors and nutrient factors in rhizosphere soil was researched by the canonical correspondence analysis method (CCA). The results show that contents of organic matter, TN, TP and TK in rhizosphere soil of different locations are 14.03-32.79, 0. 39-0. 92, 0. 56-1. 55 and 2.29-9.23 g . kg-1, respectively. Variation of nutrient content in rhizosphere soil is more obvious, and C. longa always grows in the soil with neutral to slightly acid and good property of water and fertilizer. The average contents of curcumin, demethoxycurcumin, bisdemethoxycurcumin and total curcuminoids in C. longa rhizome are 1.53% , 0.42% , 0.67% and 2.61% , respectively. Curcuminoids content in C. longa rhizome from different locations has significant difference, and that in different sampling plots and times in the same location also exists certain difference. Total content of curcuminoids in C. longa rhizome from Bobai of Guangxi is the highest (4. 29% ) , while that is the lowest (1. 73% ) from Sihui of Guangdong. The CCA analysis result shows that in geography-climate factors including longitude, latitude, altitude, average annual temperature, the extreme highest and lowest temperatures, annualprecipitation, sunshine duration, frost-free days, etc, average annual temperature and the extreme lowest temperature have extremely significant positive correlation with curcuminoids content, and in nutrient factors of rhizosphere soil including pH value, contents of organic matter, TN, TP and TK, organic matter content has an extremely significant positive correlation with curcuminoids content. It is concluded that average annual temperature, the extreme lowest temperature and

    OpenAIRE

    Coulter, Robert W.S.; Kinsky, Suzanne M.; Herrick, Amy L.; Stall, Ron D.; Bauermeister, José A.

    2015-01-01

    Purpose: Syndemics, or the co-occurrence and interaction of health problems, have been examined extensively among young men who have sex with men, but their existence remain unexamined, to our knowledge, among sexual-minority (i.e., lesbian, gay, and bisexual) women. Thus, we investigated if syndemics were present among young sexual-minority women, and if sexual-orientation discrimination was an independent variable of syndemic production.

    Kuhn, Michael A; Feigelson, Eric D

    2015-01-01

    We investigate the intrinsic stellar populations (estimated total numbers of OB and pre-main-sequence stars down to 0.1 Mo) that are present in 17 massive star-forming regions (MSFRs) surveyed by the MYStIX project. The study is based on the catalog of >31,000 MYStIX Probable Complex Members with both disk-bearing and disk-free populations, compensating for extinction, nebulosity, and crowding effects. Correction for observational sensitivities is made using the X-ray Luminosity Function (XLF) and the near-infrared Initial Mass Function (IMF)--a correction that is often not made by infrared surveys of young stars. The resulting maps of the projected structure of the young stellar populations, in units of intrinsic stellar surface density, allow direct comparison between different regions. Several regions have multiple dense clumps, similar in size and density to the Orion Nebula Cluster. The highest projected density of ~34,000 stars/pc^2 is found in the core of the RCW38 cluster. Histograms of surface densit...

    2013-05-01

    Full Text Available Norwegian authorities’ policy aims at securing an information society for all, emphasizing the importance of accessible and usable Information and Communication Technology (ICT for everyone. While the body of research on young people’s use of ICT is quite comprehensive, research addressing digital differentiation in young people with disabilities’ use of ICT is still in its early days. This article investigates how young people with disabilities’ use, or non-use, of assistive ICT creates digital differentiations. The investigation elaborates on how the anticipations and stereotypes of disability establish an authoritative definition of assistive ICT, and the consequence this creates for the use of the Web by young people with disabilities. The object of the article is to provide enhanced insight into the field of technology and disability by illuminating how assistive ICT sometimes eliminates and sometimes reproduces stereotypes and digital differentiations. The investigation draws on a qualitative interview study with 23 young Norwegians with disabilities, aged 15–20 years. I draw on a theoretical perspective to analyze the findings of the study, which employs the concept of identity multiplicity. The article’s closing discussion expands on technology’s significance in young people’s negotiations of impairment and of perceptions of disability

  13. Strokes in young adults: epidemiology and prevention

    Full Text Available Dževdet Smajlović Department of Neurology, University Clinical Centre Tuzla, School of Medicine, University of Tuzla, Bosnia and Herzegovina Abstract: Strokes in young adults are reported as being uncommon, comprising 10%–15% of all stroke patients. However, compared with stroke in older adults, stroke in the young has a disproportionately large economic impact by leaving victims disabled before their most productive years. Recent publications report an increased incidence of stroke in young adults. This is important given the fact that younger stroke patients have a clearly increased risk of death compared with the general population. The prevalence of standard modifiable vascular risk factors in young stroke patients is different from that in older patients. Modifiable risk factors for stroke, such as dyslipidemia, smoking, and hypertension, are highly prevalent in the young stroke population, with no significant difference in geographic, climatic, nutritional, lifestyle, or genetic diversity. The list of potential stroke etiologies among young adults is extensive. Strokes of undetermined and of other determined etiology are the most common types among young patients according to TOAST (Trial of Org 10172 in Acute Stroke Treatment criteria. Prevention is the primary treatment strategy aimed at reducing morbidity and mortality related to stroke. Therefore, primary prevention is very important with regard to stroke in young adults, and aggressive treatment of risk factors for stroke, such as hypertension, smoking, and dyslipidemia, is essential. The best form of secondary stroke prevention is directed toward stroke etiology as well as treatment of additional risk factors. However, there is a lack of specific recommendations and guidelines for stroke management in young adults. In conclusion, strokes in young adults are a major public health problem and further research, with standardized methodology, is needed in order to give us more

    Full Text Available In high-performance scientific software development, the emphasis is often on short time to first solution. Even when the development of new components mostly reuses existing components or libraries and only small amounts of new code must be created, dealing with the component glue code and software build processes to obtain complete applications is still tedious and error-prone. Component-based software meant to reduce complexity at the application level increases complexity to the extent that the user must learn and remember the interfaces and conventions of the component model itself. To address these needs, we introduce Bocca, the first tool to enable application developers to perform rapid component prototyping while maintaining robust software-engineering practices suitable to HPC environments. Bocca provides project management and a comprehensive build environment for creating and managing applications composed of Common Component Architecture components. Of critical importance for high-performance computing (HPC applications, Bocca is designed to operate in a language-agnostic way, simultaneously handling components written in any of the languages commonly used in scientific applications: C, C++, Fortran, Python and Java. Bocca automates the tasks related to the component glue code, freeing the user to focus on the scientific aspects of the application. Bocca embraces the philosophy pioneered by Ruby on Rails for web applications: start with something that works, and evolve it to the user's purpose.

    2015-12-01

    This study investigated the relationship between acculturation and psychological problems in Turkish and Moroccan young adults living in the Netherlands. A sample of 131 healthy young adults aged between 18 and 24 years old, with a Turkish or Moroccan background was recruited using snowball sampling. Data on acculturation, internalizing and externalizing problems, beliefs about psychological problems, attributions of psychological problems and barriers to care were collected and analyzed using Latent Class Analysis and multinomial logistic regression. Three acculturation classes were identified in moderately to highly educated, healthy Turkish or Moroccan young adults: integration, separation and diffusion. None of the participants in the sample were marginalized or assimilated. Young adults reporting diffuse acculturation reported more internalizing and externalizing problems than those who were integrated or separated. Separated young adults reported experiencing more practical barriers to care than integrated young adults. Further research with a larger sample, including young adult migrants using mental health services, is required to improve our understanding of acculturation, psychological problems and barriers to care in this population. Including experiences of discrimination in the model might improve our understanding of the relationship between different forms of acculturation and psychological problems. PMID:25845438

    Astronomy, the most accessible of all the sciences, grabs and holds the attention not only of the elders, but also that of the youngsters from all over the world. Sharing the same sky provides the unique opportunity to use it as a tool to inspire children, to encourage them to develop an interest in science and technology, but also to increase awareness of global citizenship and tolerance. We shall present a wide spectrum of educational activities dedicated to young children, especially those from less privileged backgrounds, carried out under the Universe Awareness (UNAWE) project in Poland. We will also introduce the way we follow to support teachers and educators in discovering our wonderful cosmos.

    On 27 to 31 July, CERN welcomed Paul Clarke, an 18-year-old Irish mathematician who won a CERN EIROforum prize (second place) at EUCYS 2014 (European Union Contest for Young Scientists).   Paul Clarke, visiting the new Microcosm exhibit. In addition to a €5000 prize, Paul visited the Laboratory and its experiments, meeting and speaking with CERN physicists and computer scientists. Paul's winning project is entitled "Contributions to cyclic graph theory." As the summary of the project suggests, graph theory is an area of pure mathematics which studies properties of linkages and networks. It has applications in several areas including computing, molecular structure, neuroscience, search engines, engineering etc. This project makes a profound contribution to the study of graphs. It identifies key concepts and provides the methodology to apply them to some long-standing major problems in the subject with great success. Paul has just finished high sc...

    In this paper we present Spitzer Infrared Spectrograph spectroscopy for 14 intermediate-mass young stellar objects. We use Spitzer spectroscopy to investigate the physical properties of these sources and their environments. Our sample can be divided into two types of objects: young isolated, embedded objects with spectra that are dominated by ice and silicate absorption bands, and more evolved objects that are dominated by extended emission from polycyclic aromatic hydrocarbons (PAHs) and pure H2 rotational lines. We are able to constrain the illuminating FUV fields by classifying the PAH bands below 9micron. For most of the sources we are able to detect several atomic fine structure lines. In particular, the [NeII] line appearing in two regions could originate from unresolved photodissociation regions (PDRs) or J-shocks. We relate the identified spectral features to observations obtained from NIR through submillimeter imaging. The spatial extent of several H2 and PAH bands is matched with morphologies identi...

    The past decade has seen significant progress on the direct detection and characterization of young, self-luminous giant planets at wide orbital separations from their host stars. Some of these planets show evidence for disequilibrium processes like transport-induced quenching in their atmospheres; photochemistry may also be important, despite the large orbital distances. These disequilibrium chemical processes can alter the expected composition, spectral behavior, thermal structure, and cooling history of the planets, and can potentially confuse determinations of bulk elemental ratios, which provide important insights into planet-formation mechanisms. Using a thermo/photochemical kinetics and transport model, we investigate the extent to which disequilibrium chemistry affects the composition and spectra of directly imaged giant exoplanets. Results for specific "young Jupiters" such as HR 8799 b and 51 Eri b are presented, as are general trends as a function of planetary effective temperature, surface gravity...

    The authors investigated associations between young adults' perceived purposes of emerging adulthood and their attitudes toward and participation in cohabitation. In a sample of 775 never married individuals, ages 18-29 (69% female, 69% white) from the United States, young people's perceptions of this period of life were associated with their acceptance of cohabitation, their reasoning for accepting cohabitation, and the likelihood of cohabiting. Results showed that the perception that emerging adulthood is a time to prepare for future family roles was negatively associated with acceptance of cohabitation whereas the perception that emerging adulthood is a time to take risks was positively associated with acceptance of cohabitation. The perception that emerging adulthood is a time to prepare for future family roles was associated with an increased likelihood of having cohabited while the perception that emerging adulthood is a time of possibilities was associated with a decreased likelihood of having cohabited. Implications for future research are discussed. PMID:26645897

    During a period of overinvolvement of young drivers in road accidents and an increasing number of police checks, this study was done to identify factors dissuading individuals from committing traffic violations in this segment of the population. The model used examines the perceptions of accident risk and risk of getting a ticket. A special questionnaire was designed to investigate the following subscales: Driving Offences Declared, Perceived Danger, Perceived Police Check, and Perceived Impunity. The sample tested included 514 young adults (324 men, 187 women). Analysis showed committing traffic violations was inhibited mainly by fear of danger. Sex and mileage covered influenced violations: women had a lower Driving Offences Declared score than men, and high-mileage drivers declared committing more violations than low-mileage drivers. Further, those who had ever been ticketed and who had been involved in an accident had higher scores for Driving Offences Declared. PMID:19610479

  19. Universe Awareness For Young Children

    Universe Awareness (UNAWE) is an international programme that will expose economically disadvantaged young children aged between 4 and 10 years to the inspirational aspects of modern astronomy. The programme is motivated by the premise that access to simple knowledge about the Universe is a basic birth right of everybody. These formative ages are crucial in the development of a human value system. This is also the age range in which children can learn to develop a 'feeling' for the vastness of the Universe. Exposing young children to such material is likely to broaden their minds and stimulate their world-view. The goals of Universe Awareness are in accordance with two of the United Nations Millennium goals, endorsed by all 191 UN member states, namely (i) the achievement of universal primary education and (ii) the promotion of gender equality in schools. We propose to commence Universe Awareness with a pilot project that will target disadvantaged regions in about 4 European countries (possibly Spain, France, Germany and The Netherlands) and several non-EU countries (possibly Chile, Colombia, India, Tunisia, South Africa and Venezuela). There will be two distinct elements in the development of the UNAWE program: (i) Creation and production of suitable UNAWE material and delivery techniques, (ii) Training of educators who will coordinate UNAWE in each of the target countries. In addition to the programme, an international network of astronomy outreach will be organised. We present the first results of a pilot project developed in Venezuela, where 670 children from different social environments, their teachers and members of an indigenous tribe called Ye´kuana from the Amazon region took part in a wonderful astronomical and cultural exchange that is now being promoted by the Venezuelan ministry of Education at the national level.

    This chapter demonstrates how both treatment and punishment is part of controlling young people involved in crime in the Danish welfare state. Lately there has been an increase in the use of confinement in young offenders institutions and thus a turn towards stricter punishments for crime. However......, treatment aiming at rehabilitation is still an integrated part of the system and the organization of the young offenders institutions. For the young people subjected to control both treatment and punishment are regarded as effective means of risk-control but there are also limitations and unintended results...... of exclusion and marginalization. When seeking to control young people involved in crime, the Danish social welfare state is not only social and humane but also exclusionary and at times inhumane....
