Human endogenous retroviruses (HERVs) have received much attention for their implications in the etiology of many human diseases and their profound effect on evolution. Notably, recent studies have highlighted associations between HERVs expression and cancers (Yu et al., Int J Mol Med 32, 2013), autoimmunity (Balada et al., Int Rev Immunol 29:351-370, 2010) and neurological (Christensen, J Neuroimmune Pharmacol 5:326-335, 2010) conditions. Their repetitive nature makes their study particularly challenging, where expression studies have largely focused on individual loci (De Parseval et al., J Virol 77:10414-10422, 2003) or general trends within families (Forsman et al., J Virol Methods 129:16-30, 2005; Seifarth et al., J Virol 79:341-352, 2005; Pichon et al., Nucleic Acids Res 34:e46, 2006). To refine our understanding of HERVs activity, we introduce here a new microarray, HERV-V3. This work was made possible by the careful detection and annotation of genomic HERV/MaLR sequences as well as the development of a new hybridization model, allowing the optimization of probe performances and the control of cross-reactions. RESULTS: HERV-V3 offers an almost complete coverage of HERVs and their ancestors (mammalian apparent LTR-retrotransposons, MaLRs) at the locus level along with four other repertoires (active LINE-1 elements, lncRNA, a selection of 1559 human genes and common infectious viruses). We demonstrate that HERV-V3 analytical performances are comparable with commercial Affymetrix arrays, and that for a selection of tissue/pathological specific loci, the patterns of expression measured on HERV-V3 is consistent with those reported in the literature. Given its large HERVs/MaLRs coverage and additional repertoires, HERV-V3 opens the door to multiple applications such as enhancers and alternative promoters identification, biomarkers identification as well as the characterization of genes and HERVs/MaLRs modulation caused by viral infection.

CMV-Promoter Driven Codon-Optimized Expression Alters the Assembly Type and Morphology of a Reconstituted HERV-K(HML-2

Full Text Available The HERV-K(HML-2 family contains the most recently integrated and best preserved endogenized proviral sequences in the human genome. All known elements have nevertheless been subjected to mutations or deletions that render expressed particles non-infectious. Moreover, these post-insertional mutations hamper the analysis of the general biological properties of this ancient virus family. The expression of consensus sequences and sequences of elements with reverted post-insertional mutations has therefore been very instrumental in overcoming this limitation. We investigated the particle morphology of a recently reconstituted HERV-K113 element termed oriHERV-K113 using thin-section electron microscopy (EM and could demonstrate that strong overexpression by substitution of the 5'LTR for a CMV promoter and partial codon optimization altered the virus assembly type and morphology. This included a conversion from the regular C-type to an A-type morphology with a mass of cytoplasmic immature cores tethered to the cell membrane and the membranes of vesicles. Overexpression permitted the release and maturation of virions but reduced the envelope content. A weaker boost of virus expression by Staufen-1 was not sufficient to induce these morphological alterations.

Phylogenetic Analysis Reveals That ERVs "Die Young" but HERV-H Is Unusually Conserved.

Full Text Available About 8% of the human genome is made up of endogenous retroviruses (ERVs. Though most human endogenous retroviruses (HERVs are thought to be irrelevant to our biology notable exceptions include members of the HERV-H family that are necessary for the correct functioning of stem cells. ERVs are commonly found in two forms, the full-length proviral form, and the more numerous solo-LTR form, thought to result from homologous recombination events. Here we introduce a phylogenetic framework to study ERV insertion and solo-LTR formation. We then apply the framework to site patterns sampled from a set of long alignments covering six primate genomes. Studying six categories of ERVs we quantitatively recapitulate patterns of insertional activity that are usually described in qualitative terms in the literature. A slowdown in most ERV groups is observed but we suggest that HERV-K activity may have increased in humans since they diverged from chimpanzees. We find that the rate of solo-LTR formation decreases rapidly as a function of ERV age and that an age dependent model of solo-LTR formation describes the history of ERVs more accurately than the commonly used exponential decay model. We also demonstrate that HERV-H loci are markedly less likely to form solo-LTRs than ERVs from other families. We conclude that the slower dynamics of HERV-H suggest a host role for the internal regions of these exapted elements and posit that in future it will be possible to use the relationship between full-length proviruses and solo-LTRs to help identify large scale co-options in distant vertebrate genomes.

Endogenous retroviruses (ERVs) occupy extensive regions of the human genome. Although many of these retroviral elements have lost their ability to replicate, those whose insertion took place more recently, such as the HML-2 group of HERV-K elements, still retain intact open reading frames and the capacity to produce certain viral RNA and/or proteins. Transcription of these ERVs is, however, tightly regulated by dedicated epigenetic control mechanisms. Nonetheless, it has been reported that some pathological states, such as viral infections and certain cancers, coincide with ERV expression, suggesting that transcriptional reawakening is possible. HML-2 elements are reportedly induced during HIV-1 infection, but the conserved nature of these elements has, until recently, rendered their expression profiling problematic. Here, we provide comprehensive HERV-K HML-2 expression profiles specific for productively HIV-1-infected primary human CD4 + T cells. We combined enrichment of HIV-1 infected cells using a reporter virus expressing a surface reporter for gentle and efficient purification with long-read single-molecule real-time sequencing. We show that three HML-2 proviruses-6q25.1, 8q24.3, and 19q13.42-are upregulated on average between 3- and 5-fold in HIV-1-infected CD4 + T cells. One provirus, HML-2 12q24.33, in contrast, was repressed in the presence of active HIV replication. In conclusion, this report identifies the HERV-K HML-2 loci whose expression profiles differ upon HIV-1 infection in primary human CD4 + T cells. These data will help pave the way for further studies on the influence of endogenous retroviruses on HIV-1 replication. IMPORTANCE Endogenous retroviruses inhabit big portions of our genome. Moreover, although they are mainly inert, some of the evolutionarily younger members maintain the ability to express both RNA and proteins. We have developed an approach using long-read single-molecule real-time (SMRT) sequencing that produces long reads that

Full Text Available Background/Aims. Epigenetic mechanisms via DNA methylation may be related to glaucoma pathogenesis. This study aimed to determine the global DNA methylation level of the trabeculectomy specimens among patients with different types of glaucoma and normal subjects. Methods. Trabeculectomy sections from 16 primary open-angle glaucoma (POAG, 12 primary angle-closure glaucoma (PACG, 16 secondary glaucoma patients, and 10 normal controls were assessed for DNA methylation using combined-bisulfite restriction analysis. The percentage of global methylation level of the interspersed repetitive sequences for LINE-1, Alu, HERV-E, and HERV-K were compared between the 4 groups. Results. There were no significant differences in the methylation for LINE-1 and HERV-E between patients and normal controls. For the Alu marker, the methylation was significantly lower in all types of glaucoma patients compared to controls (POAG 52.19% versus control 52.83%, p=0.021; PACG 51.50% versus control, p=0.005; secondary glaucoma 51.95% versus control, p=0.014, whereas the methylation level of HERV-K was statistically higher in POAG patients compared to controls (POAG 49.22% versus control 48.09%, p=0.017. Conclusions. The trabeculectomy sections had relative DNA hypomethylation of Alu in all glaucoma subtypes and relative DNA hypermethylation of HERV-K in POAG patients. These methylation changes may lead to the fibrotic phenotype in the trabecular meshwork.

Full Text Available Up-regulation of human endogenous retroviruses (HERVs is associated with many diseases, including cancer. In this study, an H family HERV (HERV-H-related gene was identified and characterized. Its spliced transcript lacks protein-coding capacity and may belong to the emerging class of noncoding RNAs (ncRNAs. The 1.3-kb RNA consisting of four exons is transcribed from an Alu element upstream of a 5.0-kb structurally incomplete HERV-H element. RT-PCR and quantitative RT-PCR results indicated that expression of this HERV-related transcript was negatively associated with colon, stomach, and kidney cancers. Its expression was induced upon treatment with DNA methylation and histone deacetylation inhibitors. A BLAT search using long terminal repeats (LTRs identified 50 other LTR homogenous HERV-H elements. Further analysis of these elements revealed that all are structurally incomplete and only five exert transcriptional activity. The results presented here recommend further investigation into a potentially functional HERV-H-related ncRNA.

Human endogenous retroviruses (HERV) K/W seem to play a role in fostering and exacerbation of some neurological diseases, including amyotrophic lateral sclerosis (ALS). Given these findings, the immunity response against HERV-K and HERV-W envelope surface (env-su) glycoprotein antigens in serum and cerebrospinal fluid (CSF) was investigated for ALS, multiple sclerosis (MS) and Alzheimer's disease patients and in healthy controls. Four antigenic peptides derived respectively from HERV-K and HERV-W env-su proteins were studied in 21 definite or probable ALS patients, 26 possible or definite relapsing-remitting MS patients, 18 patients with Alzheimer's disease and 39 healthy controls. An indirect enzyme-linked immunosorbent assay was set up to detect specific antibodies (Abs) against env-su peptides. Amongst the measured levels of Abs against the four different HERV-K peptide fragments, only HERV-K env-su 19-37 was significantly elevated in ALS compared to other groups, both in serum and CSF. Instead, amongst the Abs levels directed against the four different HERV-W peptide fragments, only HERV-W env-su 93-108 and HERV-W env-su 248-262 were significantly elevated, in the serum and CSF of the MS group compared to other groups. In ALS patients, the HERV-K env-su 19-37 Abs levels were significantly correlated with clinical measures of disease severity, both in serum and CSF. Increased circulating levels of Abs directed against the HERV-W env-su 93-108 and HERV-W env-su 248-262 peptide fragments could serve as possible biomarkers in patients with MS. Similarly, increased circulating levels of Abs directed against the HERV-K env-su 19-37 peptide fragment could serve as a possible early novel biomarker in patients with ALS. © 2018 EAN.

Background Human endogenous retroviruses (HERVs) are repetitive sequences derived from ancestral germ-line infections by exogenous retroviruses and different HERV families have been integrated in the genome. HERV-Fc1 in chromosome X has been previously associated with multiple sclerosis (MS) in Northern European populations. Additionally, HERV-Fc1 RNA levels of expression have been found increased in plasma of MS patients with active disease. Considering the North-South latitude gradient in MS prevalence, we aimed to evaluate the role of HERV-Fc1on MS risk in three independent Spanish cohorts. Methods A single nucleotide polymorphism near HERV-Fc1, rs391745, was genotyped by Taqman chemistry in a total of 2473 MS patients and 3031 ethnically matched controls, consecutively recruited from: Northern (569 patients and 980 controls), Central (883 patients and 692 controls) and Southern (1021 patients and 1359 controls) Spain. Our results were pooled in a meta-analysis with previously published data. Results Significant associations of the HERV-Fc1 polymorphism with MS were observed in two Spanish cohorts and the combined meta-analysis with previous data yielded a significant association [rs391745 C-allele carriers: pM-H = 0.0005; ORM-H (95% CI) = 1.27 (1.11–1.45)]. Concordantly to previous findings, when the analysis was restricted to relapsing remitting and secondary progressive MS samples, a slight enhancement in the strength of the association was observed [pM-H = 0.0003, ORM-H (95% CI) = 1.32 (1.14–1.53)]. Conclusion Association of the HERV-Fc1 polymorphism rs391745 with bout-onset MS susceptibility was confirmed in Southern European cohorts. PMID:24594754

Expression and activation by Epstein Barr virus of human endogenous retroviruses-W in blood cells and astrocytes: inference for multiple sclerosis.

Directory of Open Access Journals (Sweden)

Giuseppe Mameli

Full Text Available BACKGROUND: Proposed co-factors triggering the pathogenesis of multiple sclerosis (MS are the Epstein Barr virus (EBV, and the potentially neuropathogenic MSRV (MS-associated retrovirus and syncytin-1, of the W family of human endogenous retroviruses. METHODOLOGY/PRINCIPAL FINDINGS: In search of links, the expression of HERV-W/MSRV/syncytin-1, with/without exposure to EBV or to EBV glycoprotein350 (EBVgp350, was studied on peripheral blood mononuclear cells (PBMC from healthy volunteers and MS patients, and on astrocytes, by discriminatory env-specific RT-PCR assays, and by flow cytometry. Basal expression of HERV-W/MSRV/syncytin-1 occurs in astrocytes and in monocytes, NK, and B, but not in T cells. This uneven expression is amplified in untreated MS patients, and dramatically reduced during therapy. In astrocytes, EBVgp350 stimulates the expression of HERV-W/MSRV/syncytin-1, with requirement of the NF-κB pathway. In EBVgp350-treated PBMC, MSRVenv and syncytin-1 transcription is activated in B cells and monocytes, but not in T cells, nor in the highly expressing NK cells. The latter cells, but not the T cells, are activated by proinflammatory cytokines. CONCLUSIONS/SIGNIFICANCE: In vitro EBV activates the potentially immunopathogenic and neuropathogenic HERV-W/MSRV/syncytin-1, in cells deriving from blood and brain. In vivo, pathogenic outcomes would depend on abnormal situations, as in late EBV primary infection, that is often symptomatic, or/and in the presence of particular host genetic backgrounds. In the blood, HERV-Wenv activation might induce immunopathogenic phenomena linked to its superantigenic properties. In the brain, toxic mechanisms against oligodendrocytes could be established, inducing inflammation, demyelination and axonal damage. Local stimulation by proinflammatory cytokines and other factors might activate further HERV-Ws, contributing to the neuropathogenity. In MS pathogenesis, a possible model could include EBV as

Full Text Available Human endogenous retroviruses (HERVs and other long terminal repeat (LTR-type retrotransposons (HERV/LTRs have regulatory elements that possibly influence the transcription of host genes. We systematically identified and characterized these regulatory elements based on publicly available datasets of ChIP-Seq of 97 transcription factors (TFs provided by ENCODE and Roadmap Epigenomics projects. We determined transcription factor-binding sites (TFBSs using the ChIP-Seq datasets and identified TFBSs observed on HERV/LTR sequences (HERV-TFBSs. Overall, 794,972 HERV-TFBSs were identified. Subsequently, we identified "HERV/LTR-shared regulatory element (HSRE," defined as a TF-binding motif in HERV-TFBSs, shared within a substantial fraction of a HERV/LTR type. HSREs could be an indication that the regulatory elements of HERV/LTRs are present before their insertions. We identified 2,201 HSREs, comprising specific associations of 354 HERV/LTRs and 84 TFs. Clustering analysis showed that HERV/LTRs can be grouped according to the TF binding patterns; HERV/LTR groups bounded to pluripotent TFs (e.g., SOX2, POU5F1, and NANOG, embryonic endoderm/mesendoderm TFs (e.g., GATA4/6, SOX17, and FOXA1/2, hematopoietic TFs (e.g., SPI1 (PU1, GATA1/2, and TAL1, and CTCF were identified. Regulatory elements of HERV/LTRs tended to locate nearby and/or interact three-dimensionally with the genes involved in immune responses, indicating that the regulatory elements play an important role in controlling the immune regulatory network. Further, we demonstrated subgroup-specific TF binding within LTR7, LTR5B, and LTR5_Hs, indicating that gains or losses of the regulatory elements occurred during genomic invasions of the HERV/LTRs. Finally, we constructed dbHERV-REs, an interactive database of HERV/LTR regulatory elements (http://herv-tfbs.com/. This study provides fundamental information in understanding the impact of HERV/LTRs on host transcription, and offers insights into

A substantial part of the human genome originates from transposable elements, remnants of ancient retroviral infections. Roughly 8% of the human genome consists of about 400,000 LTR elements including human endogenous retrovirus (HERV) sequences. Mainly, the interplay between epigenetic and post-transcriptional mechanisms is thought to silence HERV expression in most physiological contexts. Interestingly, aberrant reactivation of several HERV-H loci appears specific to colorectal carcinoma (CRC). The expression of HERV-H Gag proteins (Gag-H) was assessed using novel monoclonal mouse anti Gag-H antibodies. In a flow cytometry screen four antibody clones were tested on a panel of primary CRC cell lines and the most well performing ones were subsequently validated in western blot analysis. Finally, Gag-H protein expression was analyzed by immune histology on cell line cytospins and on clinical samples. There, we found a heterogeneous staining pattern with no background staining of endothelial, stromal and infiltrating immune cells but diffuse staining of the cytoplasm for positive tumor and normal crypt cells of the colonic epithelium. Taken together, the Gag-H antibody clone(s) present a valuable tool for staining of cells with colonic origin and thus form the basis for future more detailed investigations. The observed Gag-H protein staining in colonic epithelium crypt cells demands profound analyses of a potential role for Gag-H in the normal physiology of the human gut.

Human endogenous retroviruses (HERVs) are remnants of ancestral infections and chromosomally integrated in all cells of an individual, are transmitted only vertically and are defective in viral replication. However enhanced expression of HERV-K accompanied by the emergence of anti-HERV-K-directed immune responses has been observed inter-alia in HIV-infected individuals and tumor patients. Therefore HERV-K might serve as a tumor-specific antigen or even as a constant target for the development of an HIV vaccine. To verify our hypothesis, we tested the immunogenicity of HERV-K Gag by using a recombinant vaccinia virus (MVA-HKcon) expressing the HERV-K Gag protein and established an animal model to test its vaccination efficacy. Murine renal carcinoma cells (Renca) were genetically altered to express E. coli beta-galactosidase (RLZ cells) and the HERV-K Gag protein (RLZ-HKGag cells). Subcutaneous application of RLZ-HKGag cells into syngenic BALB/c mice resulted in the formation of local tumors in MVA vaccinated mice. MVA-HKcon vaccination reduced the tumor growth. Furthermore, intravenous injection of RLZ-HKGag cells led to the formation of pulmonary metastases. Vaccination of tumor-bearing mice with MVA-HKcon drastically reduced the number of pulmonary RLZ-HKGag tumor nodules compared to vaccination with wild-type MVA. The data demonstrate that HERV-K Gag is a useful target for vaccine development and might offer new treatment opportunities for cancer patients.

On Monday 22 September, early morning, we received with enormous sadness a message that Hervé Genoud passed away after an eight-month battle with leukaemia at the age of just 32.   “Hervé s’est envolé vers la lumière,” wrote Mélissa, his wife, in her message. He sadly leaves behind his wife Mélissa and his two young children Maxence and Nathanaël. Hervé joined the BE-OP group as operator on the PS in June 2006 where he quickly integrated and became a core member of the operations team. He did not limit his work to the PS, but was also very much appreciated for his roles in the LHC quench protection system and his outreach activities, such as the CERN open days and La nuit des chercheurs. With this loss we not only lose a colleague, but also a good friend for many. We will never forget his enthusiasm, his jokes and his very positive approach, not only in his work, but also during hi...

Human Endogenous Retrovirus W Activity in Cartilage of Osteoarthritis Patients

Full Text Available The etiology of viruses in osteoarthritis remains controversial because the prevalence of viral nucleic acid sequences in peripheral blood or synovial fluid from osteoarthritis patients and that in healthy control subjects are similar. Until now the presence of virus has not been analyzed in cartilage. We screened cartilage and chondrocytes from advanced and non-/early osteoarthritis patients for parvovirus B19, herpes simplex virus-1, Epstein Barr virus, cytomegalovirus, human herpes virus-6, hepatitis C virus, and human endogenous retroviruses transcripts. Endogenous retroviruses transcripts, but none of the other viruses, were detected in 15 out the 17 patients. Sequencing identified the virus as HERV-WE1 and E2. HERV-W activity was confirmed by high expression levels of syncytin, dsRNA, virus budding, and the presence of virus-like particles in all advanced osteoarthritis cartilages examined. Low levels of HERV-WE1, but not E2 envelope RNA, were observed in 3 out of 8 non-/early osteoarthritis patients, while only 3 out of 7 chondrocytes cultures displayed low levels of syncytin, and just one was positive for virus-like particles. This study demonstrates for the first time activation of HERV-W in cartilage of osteoarthritis patients; however, a causative role for HERV-W in development or deterioration of the disease remains to be proven.

These two mountain sport enthusiasts were clearly very dear to many people, including all those who came to say a final farewell at their funerals, in Thoiry (the Ain) and Breuleux (Jura) respectively.     Hervé Milcent. Hervé arrived at CERN in 1988 under the coopérant scheme (professional work in lieu of French military service) to work on data acquisition systems for the LEP detectors, and was recruited as a staff member in 1996 in the Controls (ECP) group, which later became IT-CO, to work on the control systems for ALICE. Then he joined the LHC-IAS group and was awarded an indefinite contract. Many of the LHC’s monitoring systems owe much of their success to Hervé, who worked assiduously to test and check everything to ensure that all the systems worked from the moment they we...

The human endogenous retrovirus (HERV-K) envelope (env) protein is a tumor-associated antigen (TAA) expressed on melanoma but not normal cells. This study was designed to engineer a chimeric antigen receptor (CAR) on T-cell surface, such that they target tumors in advanced stages of melanoma. Expression of HERV-K protein was analyzed in 220 melanoma samples (with various stages of disease) and 139 normal organ donor tissues using immunohistochemical (IHC) analysis. HERV-K env-specific CAR derived from mouse monoclonal antibody was introduced into T cells using the transposon-based Sleeping Beauty (SB) system. HERV-K env-specific CAR(+) T cells were expanded ex vivo on activating and propagating cells (AaPC) and characterized for CAR expression and specificity. This includes evaluating the HERV-K-specific CAR(+) T cells for their ability to kill A375-SM metastasized tumors in a mouse xenograft model. We detected HERV-K env protein on melanoma but not in normal tissues. After electroporation of T cells and selection on HERV-K(+) AaPC, more than 95% of genetically modified T cells expressed the CAR with an effector memory phenotype and lysed HERV-K env(+) tumor targets in an antigen-specific manner. Even though there is apparent shedding of this TAA from tumor cells that can be recognized by HERV-K env-specific CAR(+) T cells, we observed a significant antitumor effect. Adoptive cellular immunotherapy with HERV-K env-specific CAR(+) T cells represents a clinically appealing treatment strategy for advanced-stage melanoma and provides an approach for targeting this TAA on other solid tumors. ©2015 American Association for Cancer Research.

BACKGROUND Morphea, also known as localized scleroderma, is a rare autoimmune connective tissue disease characterized by skin fibrosis. UVA1 phototherapy is an important asset in the reduction of clinical manifestations in morphea. There are studies claiming that UV light modulates the expression of some human endogenous retroviral sequences. The aim of this study was to determine if the expression of HERV-K10 gag element is lowered by UVA1 phototherapy in morphea, a disease in which such irradiation has a soothing effect. MATERIAL AND METHODS The expression levels of the HERV-K10 gag were assessed by real-time PCR (polymerase chain reaction) in peripheral blood mononuclear cells (PBMC) and skin-punch biopsies of healthy volunteers and 9 morphea patients before and after phototherapy. Additionally, correlations between the HERV-K10 gag expression and age, disease duration, the Localized Scleroderma Skin Severity Index (LoSSI), and antinuclear antibody (ANA) titers were assessed. RESULTS In PBMC, HERV-K10 gag mRNA was significantly elevated after UVA1 phototherapy compared to healthy controls. Most of the patients responded with an increased expression level of this sequence. However, we found no statistical evidence at this point that phototherapy indeed has an effect on the HERV-K10 gag expression (there were no statistical differences in PBMC of morphea patients before and after phototherapy). Similarly, there was no statistically relevant effect of the UVA1 on the expression of HERV-K10 gag in skin. CONCLUSIONS At this point, the effect of UVA1 phototherapy on the expression of HERV-K10 gag cannot be statistically confirmed.

Human endogenous retroviruses (HERVs) are globally silent in somatic cells. However, some HERVs display high transcription in physiological conditions. In particular, ERVWE1, ERVFRDE1 and ERV3, three proviruses of distinct families, are highly transcribed in placenta and produce envelope proteins associated with placenta development. As silencing of repeated elements is thought to occur mainly by DNA methylation, we compared the methylation of ERVWE1 and related HERVs to appreciate whether HERV methylation relies upon the family, the integration site, the tissue, the long terminal repeat (LTR) function or the associated gene function. CpG methylation of HERV-W LTRs in placenta-associated tissues was heterogeneous but a joint epigenetic control was found for ERVWE1 5′LTR and its juxtaposed enhancer, a mammalian apparent LTR retrotransposon. Additionally, ERVWE1, ERVFRDE1 and ERV3 5′LTRs were all essentially hypomethylated in cytotrophoblasts during pregnancy, but showed distinct and stage-dependent methylation profiles. In non-cytotrophoblastic cells, they also exhibited different methylation profiles, compatible with their respective transcriptional activities. Comparative analyses of transcriptional activity and LTR methylation in cell lines further sustained a role for methylation in the control of functional LTRs. These results suggest that HERV methylation might not be family related but copy-specific, and related to the LTR function and the tissue. In particular, ERVWE1 and ERV3 could be developmentally epigenetically regulated HERVs. PMID:19561344

Human endogenous retrovirus W env (HERV-W env) plays a critical role in many neuropsychological diseases such as schizophrenia and multiple sclerosis (MS). These diseases are accompanied by immunological reactions in the central nervous system (CNS). Microglia are important immunocytes in brain inflammation that can produce a gasotransmitter-nitric oxide (NO). NO not only plays a role in the function of neuronal cells but also participates in the pathogenesis of various neuropsychological diseases. In this study, we reported increased NO production in CHME-5 microglia cells after they were transfected with HERV-W env. Moreover, HERV-W env increased the expression and function of human inducible nitric oxide synthase (hiNOS) and enhanced the promoter activity of hiNOS. Microglial migration was also enhanced. These data revealed that HERV-W env might contribute to increase NO production and microglial migration ability in neuropsychological disorders by regulating the expression of inducible NOS. Results from this study might lead to the identification of novel targets for the treatment of neuropsychological diseases, including neuroinflammatory diseases, stroke, and neurodegenerative diseases.

Several lines of evidences suggest that human endogenous retroviruses (HERVs) are implicated in the development of many complex diseases with a multifactorial aetiology and a strong heritability, such as neurological and psychiatric diseases. Attention deficit hyperactivity Disorder (ADHD) is a neurodevelopmental disorder that results from a complex interaction of environmental, biological and genetic factors. Our aim was to analyse the expression levels of three HERV families (HERV-H, K and W) in patients with ADHD. The expression of retroviral mRNAs from the three HERV families was evaluated in peripheral blood mononuclear cells (PBMCs) from 30 patients with ADHD and 30 healthy controls by quantitative RT-PCR. The expression levels of HERV-H are significantly higher in patients with ADHD compared to healthy controls, while there are no differences in the expression levels of HERV-K and W. Since the ADHD aetiology is due to a complex interaction of environmental, biological and genetic factors, HERVs may represent one link among these factors and clinical phenotype of ADHD. A future confirmation of HERV-H overexpression in a larger number of ADHD patients will make possible to identify it as a new parameter for this clinical condition, also contributing to deepen the study on the role of HERVs in the neurodevelopment diseases.

Human endogenous retroviruses in neurologic disease.

Endogenous retroviruses are pathogenic - in other species than the human. Disease associations for Human Endogenous RetroViruses (HERVs) are emerging, but so far an unequivocal pathogenetic cause-effect relationship has not been established. A role for HERVs has been proposed in neurological and neuropsychiatric diseases as diverse as multiple sclerosis (MS) and schizophrenia (SCZ). Particularly for MS, many aspects of the activation and involvement of specific HERV families (HERV-H/F and HERV-W/MSRV) have been reported, both for cells in the circulation and in the central nervous system. Notably envelope genes and their gene products (Envs) appear strongly associated with the disease. For SCZ, for ALS, and for HIV-associated dementia (HAD), indications are accumulating for involvement of the HERV-K family, and also HERV-H/F and/or HERV-W. Activation is reasonably a prerequisite for causality as most HERV sequences remain quiescent in non-pathological conditions, so the importance of regulatory pathways and epigenetics involved in regulating HERV activation, derepression, and also involvement of retroviral restriction factors, is emerging. HERV-directed antiretrovirals have potential as novel therapeutic paradigms in neurologic disease, particularly in MS. The possible protective or ameliorative effects of antiretroviral therapy in MS are substantiated by reports that treatment of HIV infection may be associated with a significantly decreased risk of MS. Further studies of HERVs, their role in neurologic diseases, and their potential as therapeutic targets are essential. © 2016 APMIS. Published by John Wiley & Sons Ltd.

Purpose We investigated the role of the human endogenous retrovirus type K (HERV-K) envelope (env) gene in pancreatic cancer (PC). Experimental Design shRNA was employed to knockdown (KD) the expression of HERV-K in PC cells. Results HERV-K env expression was detected in seven PC cell lines and in 80% of PC patient biopsies, but not in two normal pancreatic cell lines or uninvolved normal tissues. A new HERV-K splice variant was discovered in several PC cell lines. RT activity and virus-like particles were observed in culture media supernatant obtained from Panc-1 and Panc-2 cells. HERV-K viral RNA levels and anti-HERV-K antibody titers were significantly higher in PC patient sera (N=106) than in normal donor sera (N=40). Importantly, the in vitro and in vivo growth rates of three PC cell lines were significantly reduced after HERV-K KD by shRNA targeting HERV-K env, and there was reduced metastasis to lung after treatment. RNA-seq results revealed changes in gene expression after HERV-K env KD, including RAS and TP53. Furthermore, downregulation of HERV-K Env protein expression by shRNA also resulted in decreased expression of RAS, p-ERK, p-RSK, and p-AKT in several PC cells or tumors. Conclusion These results demonstrate that HERV-K influences signal transduction via the RAS-ERK-RSK pathway in PC. Our data highlight the potentially important role of HERV-K in tumorigenesis and progression of PC, and indicate that HERV-K viral proteins may be attractive biomarkers and/or tumor-associated antigens, as well as potentially useful targets for detection, diagnosis and immunotherapy of PC.

Psoriasis is a multifactorial, chronic disease of skin affecting 2-3% of the world's population. Genetic studies of psoriasis have identified a number of susceptibility genes that are involved in anti-viral immunity. Furthermore, physiological studies have also found an increase in anti-viral proteins in psoriatic skin. These findings suggest the presence of an anti-viral state in psoriatic skin. However, the triggers for this anti-viral cascade and its consequences for host immunity are not known. Endogenous retroviruses have previously been described in many autoimmune diseases including psoriasis. In the present study we examined the humoral immune response against human endogenous retrovirus-K (HERV-K) proteins and the cutaneous expression levels of multiple HERV-K genes in psoriasis patients and healthy controls. In psoriatic sera we observed a significant decrease in IgM response against three HERV-K proteins: Env surface unit (SU), Env transmembrane protein (TM), and Gag capsid (CA) in comparison to sera obtained from blood bank healthy controls. A decrease in IgG response was also observed against CA. Furthermore, using quantitative RT-PCR we observed a decrease in the expression of HERV-K Env, Gag, Pol and Rec as well as ERV-9 genes in lesional psoriatic skin as compared to healthy skin. Together, our results suggest that the pro-inflammatory, anti-viral state in psoriasis is associated with diminished expression of HERV-K gene transcripts and a concomitant decrease in humoral responses to HERV-K. Our results indicate that a simple model where continuous, minimally changing HERV-K expression serves as an antigenic trigger in psoriasis might not be correct and further studies are needed to decipher the possible relationship between psoriasis and HERVs.

A Review of Le Corbusier & Lucien Hervé. The Architect & the Photographer: a Dialogue

Full Text Available Originally published in French under the evocative title 'Le Corbusier / Lucien Hervé / Contacts (L’ Atelier d’édition, 2011, Le Corbusier & Lucien Hervé. The Architect & the Photographer: a Dialogue 'turns our gaze, perhaps for the first time, away from the artistic importance of the photographs themselves that only indirectly illuminate the architectural value of the images. Jacques Sbriglio, editor of the book, has selected sixteen buildings by Le Corbusier - from Paris to Ronchamp, from Chandigarh to Roquebrune-Cap-Martin: he briefly describes each of them, and illustrates the texts with a selection of contact prints made by Hervé and held today in the Fondation Le Corbusier. In the Fondation there are thousands of contact prints, all assembled on 1,200 colourful pieces of cardboard: 184 of these can now be seen in this new publication. The sheets represent the channel of communication between the photographer and the architect, so the former could select images to illustrate particular aspects of each project. Sometimes Le Corbusier produced sketches from the contact prints and sent these drawings to Lucien Hervé so the photographer could select a particular image from the archive.

Human endogenous retroviruses and multiple sclerosis: innocent bystanders or disease determinants?

Human endogenous retroviruses (HERVs) constitute 5-8% of human genomic DNA and are replication incompetent despite expression of individual HERV genes from different chromosomal loci depending on the specific tissue. Several HERV genes have been detected as transcripts and proteins in the central nervous system, frequently in the context of neuroinflammation. The HERV-W family has received substantial attention in large part because of associations with diverse syndromes including multiple sclerosis (MS) and several psychiatric disorders. A HERV-W-related retroelement, multiple sclerosis retrovirus (MSRV), has been reported in MS patients to be both a biomarker as well as an effector of aberrant immune responses. HERV-H and HERV-K have also been implicated in MS and other neurological diseases but await delineation of their contributions to disease. The HERV-W envelope-encoded glycosylated protein, syncytin-1, is encoded by chromosome 7q21 and exhibits increased glial expression within MS lesions. Overexpression of syncytin-1 in glia induces endoplasmic reticulum stress leading to neuroinflammation and the induction of free radicals, which damage proximate cells. Syncytin-1's receptor, ASCT1 is a neutral amino acid transporter expressed on glia and is suppressed in white matter of MS patients. Of interest, antioxidants ameliorate syncytin-1's neuropathogenic effects raising the possibility of using these agents as therapeutics for neuroinflammatory diseases. Given the multiple insertion sites of HERV genes as complete and incomplete open reading frames, together with their differing capacity to be expressed and the complexities of individual HERVs as both disease markers and bioactive effectors, HERV biology is a compelling area for understanding neuropathogenic mechanisms and developing new therapeutic strategies. 2010 Elsevier B.V.

Testimony to Muzil: Hervé Guibert, Michel Foucault, and the "Medical Gaze" examines the fictional/autobiographical AIDS writings of the French writer Hervé Guibert. Locating Guibert's writings alongside the work of his friend Michel Foucault, the article explores how they echo Foucault's evolving notions of the "medical gaze." The article also explores how Guilbert's narrators and Guibert himself (as writer) resist and challenge the medical gaze; a gaze which particularly in the era of AIDS has subjected, objectified, and even sometimes punished the body of the gay man. It is argued that these resistances to the gaze offer a literary extension to Foucault's later work on power and resistance strategies.

vW leptokurtic asteroid families are families for which the distribution of the normal component of the terminal ejection velocity field vW is characterized by a positive value of the γ2 Pearson kurtosis, I.e. they have a distribution with a more concentrated peak and larger tails than the Gaussian one. Currently, eight families are known to have γ2(vW) > 0.25. Among these, three are highly inclined asteroid families, the Hansa, Barcelona, and Gallia families. As observed for the case of the Astrid family, the leptokurtic inclination distribution seems to be caused by the interaction of these families with node secular resonances. In particular, the Hansa and Gallia family are crossed by the s - sV resonance with Vesta, that significantly alters the inclination of some of their members. In this work we use the time evolution of γ2(vW) for simulated families under the gravitational influence of all planets and the three most massive bodies in the main belt to assess the dynamical importance (or lack of) node secular resonances with Ceres, Vesta, and Pallas for the considered families, and to obtain independent constraints on the family ages. While secular resonances with massive bodies in the main belt do not significantly affect the dynamical evolution of the Barcelona family, they significantly increase the γ2(vW) values of the simulated Hansa and Gallia families. Current values of the γ2(vW) for the Gallia family are reached over the estimated family age only if secular resonances with Vesta are accounted for.

Transcriptional Modulation of Human Endogenous Retroviruses in Primary CD4+ T Cells Following Vorinostat Treatment

Full Text Available The greatest obstacle to a cure for HIV is the provirus that integrates into the genome of the infected cell and persists despite antiretroviral therapy. A “shock and kill” approach has been proposed as a strategy for an HIV cure whereby drugs and compounds referred to as latency-reversing agents (LRAs are used to “shock” the silent provirus into active replication to permit “killing” by virus-induced pathology or immune recognition. The LRA most utilized to date in clinical trials has been the histone deacetylase (HDAC inhibitor—vorinostat. Potentially, pathological off-target effects of vorinostat may result from the activation of human endogenous retroviruses (HERVs, which share common ancestry with exogenous retroviruses including HIV. To explore the effects of HDAC inhibition on HERV transcription, an unbiased pharmacogenomics approach (total RNA-Seq was used to evaluate HERV expression following the exposure of primary CD4+ T cells to a high dose of vorinostat. Over 2,000 individual HERV elements were found to be significantly modulated by vorinostat, whereby elements belonging to the ERVL family (e.g., LTR16C and LTR33 were predominantly downregulated, in contrast to LTR12 elements of the HERV-9 family, which exhibited the greatest signal, with the upregulation of 140 distinct elements. The modulation of three different LTR12 elements by vorinostat was confirmed by droplet digital PCR along a dose–response curve. The monitoring of LTR12 expression during clinical trials with vorinostat may be indicated to assess the impact of this HERV on the human genome and host immunity.

Introduction Morphea (localized scleroderma) is a relatively rare disease characterized by excessive skin fibrosis. Human endogenous retroviruses (HERV) are largely distributed within the human genome with hundreds of thousands of elements. The HERV have been widely studied in autoimmune disorders, yet hardly ever assessed in diseases with a good prognosis such as morphea. Aim In this study we focus on the possible relations between the expression of chosen HERV and factors influencing the pathomechanism of the disease, such as age, sex, titres of anti-nuclear antibodies, as well as duration, activity, and severity of the disease (LoSSI index). Material and methods Real-time polymerase chain reaction (PCR) targeting six HERV sequences of interest were performed on samples derived from peripheral blood mononuclear cells (PBMC) and skin biopsies. Results In PBMC we found a statistically significant negative correlation between HERV-W env expression and LoSSI index (p = 0.01). Additionally, HERV-W env was downregulated in patients with the active form of morphea. In all other cases we found no correlation whatsoever nor statistically significant differences below the p = 0.05 threshold. Conclusions Morphea seems to be an autoimmune disease where the impact of HERV is not so apparent. It seems that probing many patients for the expression of just a few sequences is not as effective as previously expected. For initial studies of HERV in other diseases we recommend high throughput techniques such as HERV-dedicated DNA microarrays or massive parallel sequencing. PMID:28261031

Friends-enemies: endogenous retroviruses are major transcriptional regulators of human DNA

Science.gov (United States)

Buzdin, Anton A.; Prassolov, Vladimir; Garazha, Andrew V.

Endogenous retroviruses are mobile genetic elements hardly distinguishable from infectious, or “exogenous”, retroviruses at the time of insertion in the host DNA. Human endogenous retroviruses (HERVs) are not rare. They gave rise to multiple families of closely related mobile elements that occupy 8% of the human genome. Together, they shape genomic regulatory landscape by providing at least 320,000 human transcription factor binding sites (TFBS) located on 110,000 individual HERV elements. The HERVs host as many as 155,000 mapped DNaseI hypersensitivity sites, which denote loci active in the regulation of gene expression or chromatin structure. The contemporary view of the HERVs evolutionary dynamics suggests that at the early stages after insertion, the HERV is treated by the host cells as a foreign genetic element, and is likely to be suppressed by the targeted methylation and mutations. However, at the later stages, when significant number of mutations has been already accumulated and when the retroviral genes are broken, the regulatory potential of a HERV may be released and recruited to modify the genomic balance of transcription factor binding sites. This process goes together with further accumulation and selection of mutations, which reshape the regulatory landscape of the human DNA. However, developmental reprogramming, stress or pathological conditions like cancer, inflammation and infectious diseases, can remove the blocks limiting expression and HERV-mediated host gene regulation. This, in turn, can dramatically alter the gene expression equilibrium and shift it to a newer state, thus further amplifying instability and exacerbating the stressful situation.

An estimated 10-20 million individuals are infected with the retrovirus human T-cell leukemia virus type 1 (HTLV-1). While the majority of these individuals remain asymptomatic, 0.3-4% develop a neurodegenerative inflammatory disease, termed HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP). HAM/TSP results in the progressive demyelination of the central nervous system and is a differential diagnosis of multiple sclerosis (MS). The etiology of HAM/TSP is unclear, but evidence points to a role for CNS-inflitrating T-cells in pathogenesis. Recently, the HTLV-1-Tax protein has been shown to induce transcription of the human endogenous retrovirus (HERV) families W, H and K. Intriguingly, numerous studies have implicated these same HERV families in MS, though this association remains controversial. Here, we explore the hypothesis that HTLV-1-infection results in the induction of HERV antigen expression and the elicitation of HERV-specific T-cells responses which, in turn, may be reactive against neurons and other tissues. PBMC from 15 HTLV-1-infected subjects, 5 of whom presented with HAM/TSP, were comprehensively screened for T-cell responses to overlapping peptides spanning HERV-K(HML-2) Gag and Env. In addition, we screened for responses to peptides derived from diverse HERV families, selected based on predicted binding to predicted optimal epitopes. We observed a lack of responses to each of these peptide sets. Thus, although the limited scope of our screening prevents us from conclusively disproving our hypothesis, the current study does not provide data supporting a role for HERV-specific T-cell responses in HTLV-1 associated immunopathology.

At the summit of Sustainable Development, by Hervé Dessimoz and Thomas Büchi.   Globe de la science et de l'innovation Route de Meyrin, 1211 Genève Tuesday 14 May 2013 at 8:30 p.m. The lecture will be in French Refuge du Goûter. Hervé Dessimoz and Thomas Büchi have been committed to sustainable development since the 2000s. They created the Palais de l’Équilibre at Expo.02. They designed an exhibition in conjunction with the Cité de la Science et de l’Industrie (Paris) to educate visitors about sustainable development. The pavilion was donated to CERN by the Swiss Confederation and rebuilt on the CERN site in 2004. It is now known as the Globe of Science and Innovation. The Refuge du Goûter, on the slopes of Mont Blanc, is the culmination of their research into sustainable development, with the aim of demonstrating that if we can construct a building at 3835 m which is a...

Short interspersed nuclear elements (SINEs) are non-long terminal repeat retrotransposons that are highly abundant, heterogeneous, and mostly not annotated in eukaryotic genomes. We developed a tool designated SINE-Finder for the targeted discovery of tRNA-derived SINEs. We analyzed sequence data of 16 plant genomes, including 13 angiosperms and three gymnosperms and identified 17,829 full-length and truncated SINEs falling into 31 families showing the widespread occurrence of SINEs in higher plants. The investigation focused on potato (Solanum tuberosum), resulting in the detection of seven different SolS SINE families consisting of 1489 full-length and 870 5′ truncated copies. Consensus sequences of full-length members range in size from 106 to 244 bp depending on the SINE family. SolS SINEs populated related species and evolved separately, which led to some distinct subfamilies. Solanaceae SINEs are dispersed along chromosomes and distributed without clustering but with preferred integration into short A-rich motifs. They emerged more than 23 million years ago and were species specifically amplified during the radiation of potato, tomato (Solanum lycopersicum), and tobacco (Nicotiana tabacum). We show that tobacco TS retrotransposons are composite SINEs consisting of the 3′ end of a long interspersed nuclear element integrated downstream of a nonhomologous SINE family followed by successfully colonization of the genome. We propose an evolutionary scenario for the formation of TS as a spontaneous event, which could be typical for the emergence of SINE families. PMID:21908723

LINE-1 (Long Interspersed Nuclear Elements) and HERVs (Human Endogenous Retroviruses) are two families of autonomously replicating retrotransposons that together account for about 28% of the human genome. Genes harbored within LINE-1 and HERV retrotransposons, particularly those encoding the reverse transcriptase (RT) enzyme, are generally expressed at low levels in differentiated cells, but their expression is upregulated in transformed cells and embryonic tissues. Here we discuss a recently discovered RT-dependent mechanism that operates in tumorigenesis and reversibly modulates phenotypic and functional variations associated with tumor progression. Downregulation of active LINE-1 elements drastically reduces the tumorigenic potential of cancer cells, paralleled by reduced proliferation and increased differentiation. Pharmacological RT inhibitors (e.g., nevirapine and efavirenz) exert similar effects on tumorigenic cell lines, both in culture and in animal models. The HERV-K family play a distinct complementary role in stress-dependent transition of melanoma cells from an adherent, non-aggressive, to a non-adherent, highly malignant, growth phenotype. In synthesis, the retrotransposon-encoded RT is increasingly emerging as a key regulator of tumor progression and a promising target in a novel anti-cancer therapy

The etiology of multiple sclerosis (MS) is still unclear. The immuno-pathogenic phenomena leading to neurodegeneration are thought to be triggered by environmental (viral?) factors operating on predisposing genetic backgrounds. Among the proposed co-factors are the Epstein Barr virus (EBV), and the potentially neuropathogenic HERV-W/MSRV/Syncytin-1 endogenous retroviruses. The ascertained links between EBV and MS are history of late primary infection, possibly leading to infectious mononucleosis (IM), and high titers of pre-onset IgG against EBV nuclear antigens (anti-EBNA IgG). During MS, there is no evidence of MS-specific EBV expression, while a continuous expression of HERV-Ws occurs, paralleling disease behaviour. We found repeatedly extracellular HERV-W/MSRV and MSRV-specific mRNA sequences in MS patients (in blood, spinal fluid, and brain samples), and MRSV presence/load strikingly paralleled MS stages and active/remission phases. Aim of the study was to verify whether HERV-W might be activated in vivo, in hospitalized young adults with IM symptoms, that were analyzed with respect to expression of HERV-W/MSRV transcripts and proteins. Healthy controls were either EBV-negative or latently EBV-infected with/without high titers of anti-EBNA-1 IgG. The results show that activation of HERV-W/MSRV occurs in blood mononuclear cells of IM patients (2Log10 increase of MSRV-type env mRNA accumulation with respect to EBV-negative controls). When healthy controls are stratified for previous EBV infection (high and low, or no anti-EBNA-1 IgG titers), a direct correlation occurs with MSRV mRNA accumulation. Flow cytometry data show increased percentages of cells exposing surface HERV-Wenv protein, that occur differently in specific cell subsets, and in acute disease and past infection. Thus, the data indicate that the two main links between EBV and MS (IM and high anti-EBNA-1-IgG titers) are paralleled by activation of the potentially neuropathogenic HERV-W/MSRV. These

Report on the intercomparison of determination of selected radionuclides and trace elements in water (W-1, W-2 and W-3, 1975-76)

Energy Technology Data Exchange (ETDEWEB)

1976-12-01

Water is one of the most common materials which are analyzed for the purpose of monitoring of environmental pollution. While being an apparently 'easy' matrix it can in fact pose serious problems even for an experienced analyst. Trace elements and radionuclides may 'disappear' from aqueous solutions due to adsorption on container walls and some of them due to volatilization, bacterial action, etc. Preconcentration techniques such as evaporation and freeze-drying may also lead to considerable losses of some elements. On the other hand, when the vessels employed for storing the water samples have not been adequately cleaned, some trace elements may be 'added' to the solution. The above mentioned difficulties can probably, at least in part, account for the fact that only a small part of the participating laboratories sent in their results before the original deadline. Even after setting the new deadline (30 January 1976) the results were flowing in very sluggishly over a period of a few months what obviously delayed the preparation of this report. Altogether 46 laboratories participated in the W-1 and W-2 runs and 35 in the W-3 run but only a few determined all or most of radionuclides or trace elements, respectively. The present intercomparisons were intended to provide the opportunity of checking up the analytical performance for the laboratories dealing with low level activity measurements in water as well as for those engaged in trace multielement analysis.

The definitive demonstration of a role for a recently acquired gene is a difficult task, requiring exhaustive genetic investigations and functional analysis. The situation is indeed much more complicated when facing multicopy gene families, because most or portions of the gene are conserved among the hundred copies of the family. This is the case for the ERVWE1 locus of the human endogenous retrovirus W family (HERV-W), which encodes an envelope glycoprotein (syncytin) likely involved in trophoblast differentiation. Here we describe, in 155 individuals, the positional conservation of this locus and the preservation of the envelope ORF. Sequencing of the critical elements of the ERVWE1 provirus showed a striking conservation among the 48 alleles of 24 individuals, including the LTR elements involved in the transcriptional machinery, the splice sites involved in the maturation of subgenomic Env mRNA, and the Env ORF. The functionality and tissue specificity of the 5′ LTR were demonstrated, as well as the fusogenic activity of the envelope polymorphic variants. Such functions were also shown to be preserved in the orthologous loci isolated from chimpanzee, gorilla, orangutan, and gibbon. This functional preservation among humans and during evolution strongly argued for the involvement of this recently acquired retroviral envelope glycoprotein in hominoid placental physiology.

charakterze rodzinnym. W ramach promocji zdrowia rodziny warto popularyzować prozdrowotną rolę aktywności turystycznej oraz kształtować zachowania zdrowotne związane z bezpiecznym podróżowaniem.     Abstract   Introduction. According to a family development theory, family environment evolves and each stage constitutes a phase in which a structure and functioning are different. It is reflected in healthy life style undertaken by a family. One of the forms of pro-health behaviours which transforms in ontogenesis and depends on current social and life conditions is physical activity. Tourism is an important kind of family’s physical activity. Aim. Therefore, the aim of this paper is to analyse preferences of tourist activity among young people with diversified family situation in the context of strengthening  health potential of a family. Materials and methods. The research was carried out in year 2015, in a group of 200 women at the I and II stage of family ontogenesis. Methods of a diagnostic poll and authorial questionnaire were used. In statistical analysis chi-square test and Fisher’s Exact Test were applied. Results and conclusions.  The examined families form I and II stage of ontogenesis differ with respect to frequency of travelling (p<0.01, choice of surroundings during holiday travels (p<0.05 and preferred boarding (p<0.01. Similarities are noticed in preferred transport, distance, accommodation and duration of holidays. Families with young children more often pay attention to health aspects of travelling. However, only one third of the respondents consult a doctor prior to journey. Family is an essential element of a contemporary tourist market. Travel agencies should expand their family offers. It is worth popularising pro-health role of tourist activity within family health promotion, as well as shaping health behaviours related to safe travelling.   Słowa kluczowe: zdrowy styl życia, ontogeneza, cykl życia rodziny, aktywność turystyczna Key

Diversity and repertoire of IgW and IgM VH families in the newborn nurse shark.

Adult cartilaginous fish express three immunoglobulin (Ig) isotypes, IgM, IgNAR and IgW. Newborn nurse sharks, Ginglymostoma cirratum, produce 19S (multimeric) IgM and monomeric/dimeric IgM1gj, a germline-joined, IgM-related VH, and very low amounts of 7S (monomeric) IgM and IgNAR proteins. Newborn IgNAR VH mRNAs are diverse in the complementarity-determining region 3 (CDR3) with non-templated nucleotide (N-region) addition, which suggests that, unlike in many other vertebrates, terminal deoxynucleotidyl transferase (TdT) expressed at birth is functional. IgW is present in the lungfish, a bony fish sharing a common ancestor with sharks 460 million years ago, implying that the IgW VH family is as old as the IgM VH family. This nurse shark study examined the IgM and IgW VH repertoire from birth through adult life, and analyzed the phylogenetic relationships of these gene families. IgM and IgW VH cDNA clones isolated from newborn nurse shark primary and secondary lymphoid tissues had highly diverse and unique CDR3 with N-region addition and VDJ gene rearrangement, implicating functional TdT and RAG gene activity. Despite the clear presence of N-region additions, newborn CDR3 were significantly shorter than those of adults. The IgM clones are all included in a conventional VH family that can be classified into five discrete groups, none of which is orthologous to IgM VH genes in other elasmobranchs. In addition, a novel divergent VH family was orthologous to a published monotypic VH horn shark family. IgW VH genes have diverged sufficiently to form three families. IgM and IgW VH serine codons using the potential somatic hypermutation hotspot sequence occur mainly in VH framework 1 (FR1) and CDR1. Phylogenetic analysis of cartilaginous fish and lungfish IgM and IgW demonstrated they form two major ancient gene groups; furthermore, these VH genes generally diversify (duplicate and diverge) within a species.

Association of endogenous retroviruses and long terminal repeats with human disorders

Full Text Available Since the human genome sequences became available in 2001, our knowledge about the human transposable elements which comprise ~40% of the total nucleotides has been expanding. Non- LTR (long terminal repeat retrotransposons are actively transposing in the present-day human genome, and have been found to cause ~100 identified clinical cases of varied disorders. In contrast, almost all of the human endogenous retroviruses (HERVs originating from ancient infectious retroviruses lost their infectivity and transposing activity at various times before the human-chimpanzee speciation (~6 million years ago, and no known HERV is presently infectious. Insertion of HERVs and mammalian apparent LTR retrotransposons (MaLRs into the chromosomal DNA influenced a number of host genes in various modes during human evolution. Apart from the aspect of genome evolution, HERVs and solitary LTRs being suppressed in normal biological processes can potentially act as extra transcriptional apparatuses of cellular genes by re-activation in individuals. There has been a reasonable prediction that aberrant LTR activation could trigger malignant disorders and autoimmune responses if epigenetic changes including DNA hypomethylation occur in somatic cells. Evidence supporting this hypothesis has begun to emerge only recently: a MaLR family LTR activation in the pathogenesis of Hodgkin’s lymphoma and a HERV-E antigen expression in an anti-renal cell carcinoma immune response. This mini review addresses the impacts of the remnant-form LTR retrotransposons on human pathogenesis.

The assembly of the highly-loaded target plates of the WENDELSTEIN 7-X (W7-X) divertor requires the fabrication of 890 target elements (TEs). The plasma facing material is made of CFC NB31 flat tiles bonded to a CuCrZr copper alloy water-cooled heat sink. The elements are designed to remove a stationary heat flux and power up to 10 MW m -2 and 100 kW, respectively. Before launching the serial fabrication, pre-series activities aimed at qualifying the design, the manufacturing route and the non-destructive examinations (NDEs). High heat flux (HHF) tests performed on full-scale pre-series TEs resulted in an improvement of the design of the bond between tiles and heat sink to reduce the stresses during operation. The consequence is the fabrication of additional pre-series TEs to be tested in the HHF facility GLADIS. NDEs of this bond based on thermography methods are developed to define the acceptance criteria suitable for serial fabrication

1985-05-01

The report presents results of a laboratory intercomparison on the determination of trace elements in simulated fresh water. 20 trace elements were analyzed by 38 laboratories from 21 countries. The results of the reported comparison confirm the agreement of the nominal concentration values of trace elements in the IAEA/W-4 simulated fresh water with the determined values of these elements. They also confirm that concentrated solutions of this type can be stored in quartz ampoules without any noticeable changes due to the adsorption of trace components on the quartz wall of vessels for considerable time. The concentration values of trace elements could be certified and the material IAEA/W-4 simulated fresh water issued as a reference material. 84% of all results were obtained either by atomic absorption or by atomic emission spectroscopy

An N-Reactor outer fuel element that had been stored underwater in the Hanford 100 Area K-East Basin was subjected to a combination of low- and high-temperature vacuum drying treatments. These studies are part of a series of tests being conducted by Pacific Northwest National Laboratory on the drying behavior of N-Reactor spent nuclear fuel elements removed from both the K-West and K-East Basins. The drying test series was designed to test fuel elements that ranged from intact to severely damaged. The fuel element discussed in this report was removed from an open K-East canister (3128W) during the first fuel selection campaign conducted in 1995, and has remained in wet storage in the Postirradiation Testing Laboratory (PTL, 327 Building) since that time. Although it was judged to be breached during in-basin (i.e., K-Basin) examinations, visual inspection of this fuel element in the hot cell indicated that it was likely intact. Some scratches on the coating covering the cladding were identified before the furnace test. The drying test was conducted in the Whole Element Furnace Testing System located in G-Cell within the PTL. This test system is composed of three basic systems: the in-cell furnace equipment, the system gas loop, and the analytical instrument package. Element 3128W was subjected to the drying processes based on those proposed under the Integrated Process Strategy, which included a hot drying step. Results of the Pressure Rise and Gas Evolution Tests suggest that most of the free water in the system was released during the extended CVD cycle (68 hr versus 8 hr for the first run). An additional ∼0.34 g of water was released during the subsequent HVD phase, characterized by multiple water release peaks, with a principle peak at ∼180 C. This additional water is attributed to decomposition of a uranium hydrate (UO 4 ·4H 2 O/UO 4 ·2H 2 O) coating that was observed to be covering the surface of the fuel element to a thickness of ∼1.6 mg/cm 2 .

The genomes of chum salmon and pink salmon contain a family of short interspersed repetitive elements (SINEs), designated the salmon SmaI family. It is restricted to these two species, a distribution that suggests that this SINE family might have been generated in their common ancestor. When insertions of the SmaI SINEs at 10 orthologous loci of these species were analyzed, however, it was found that there were no shared insertion sites between chum and pink salmon. Furthermore, at six loci w...

These elements are in most cases defective, but open reading frames can still be found for the retroviral envelope gene, with sixteen such genes identified so far. Several of them are conserved during primate evolution, having possibly been co-opted by their host for a physiological role. Results To characterize further their status, we presently sequenced 12 of these genes from a panel of 91 Caucasian individuals. Genomic analyses reveal strong sequence conservation (only two non synonymous Single Nucleotide Polymorphisms [SNPs] for the two HERV-W and HERV-FRD envelope genes, i.e. for the two genes specifically expressed in the placenta and possibly involved in syncytiotrophoblast formation. We further show – using an ex vivo fusion assay for each allelic form – that none of these SNPs impairs the fusogenic function. The other envelope proteins disclose variable polymorphisms, with the occurrence of a stop codon and/or frameshift for most – but not all – of them. Moreover, the sequence conservation analysis of the orthologous genes that can be found in primates shows that three env genes have been maintained in a fully coding state throughout evolution including envW and envFRD. Conclusion Altogether, the present study strongly suggests that some but not all envelope encoding sequences are bona fide genes. It also provides new tools to elucidate the possible role of endogenous envelope proteins as susceptibility factors in a number of pathologies where HERVs have been suspected to be involved.

Full Text Available Abstract Background Mouse mammary tumor virus (MMTV encodes the Rem protein, an HIV Rev-like protein that enhances nuclear export of unspliced viral RNA in rodent cells. We have shown that Rem is expressed from a doubly spliced RNA, typical of complex retroviruses. Several recent reports indicate that MMTV can infect human cells, suggesting that MMTV might interact with human retroviruses, such as human immunodeficiency virus (HIV, human T-cell leukemia virus (HTLV, and human endogenous retrovirus type K (HERV-K. In this report, we test whether the export/regulatory proteins of human complex retroviruses will increase expression from vectors containing the Rem-responsive element (RmRE. Results MMTV Rem, HIV Rev, and HTLV Rex proteins, but not HERV-K Rec, enhanced expression from an MMTV-based reporter plasmid in human T cells, and this activity was dependent on the RmRE. No RmRE-dependent reporter gene expression was detectable using Rev, Rex, or Rec in HC11 mouse mammary cells. Cell fractionation and RNA quantitation experiments suggested that the regulatory proteins did not affect RNA stability or nuclear export in the MMTV reporter system. Rem had no demonstrable activity on export elements from HIV, HTLV, or HERV-K. Similar to the Rem-specific activity in rodent cells, the RmRE-dependent functions of Rem, Rev, or Rex in human cells were inhibited by a dominant-negative truncated nucleoporin that acts in the Crm1 pathway of RNA and protein export. Conclusion These data argue that many retroviral regulatory proteins recognize similar complex RNA structures, which may depend on the presence of cell-type specific proteins. Retroviral protein activity on the RmRE appears to affect a post-export function of the reporter RNA. Our results provide additional evidence that MMTV is a complex retrovirus with the potential for viral interactions in human cells.

Fully relativistic, four-component density functional theory electronic structure calculations were performed for M(CO)6 of group-6 elements Cr, Mo, W, and element 106, Sg, with an aim to predict their adsorption behaviour in the gas-phase chromatography experiments. It was shown that seaborgium hexacarbonyl has a longer M-CO bond, smaller ionization potential, and larger polarizability than the other group-6 molecules. This is explained by the increasing relativistic expansion and destabilization of the (n - 1)d AOs with increasing Z in the group. Using results of the calculations, adsorption enthalpies of the group-6 hexacarbonyls on a quartz surface were predicted via a model of physisorption. According to the results, -ΔHads should decrease from Mo to W, while it should be almost equal--within the experimental error bars--for W and Sg. Thus, we expect that in the future gas-phase chromatography experiments it will be almost impossible--what concerns ΔHads--to distinguish between the W and Sg hexacarbonyls by their deposition on quartz.

The non-destructive examination (NDE) method is one of the key issues in developing highly loaded plasma-facing components (PFCs) for a next generation fusion devices such as W7-X and ITER. The most critical step is certainly the fabrication and the examination of the bond between the armour and the heat sink. Two inspection systems based on the infrared thermography methods, namely, the transient thermography (SATIR-CEA) and the pulsed thermography (ARGUS-PLANSEE), are being developed and have been applied to the pre-series of target elements of the W7-X divertor. Results obtained from qualification experiences performed on target elements with artificial calibrated defects allowed to demonstrate the capability of the two techniques and raised the efficiency of inspection to a level which is appropriate for industrial application.

The W-Beijing family is a widespread Mycobacterium tuberculosis clonal lineage that frequently causes epidemic outbreaks. This family is genetically homogeneous and conserved, so ETR-VNTR (exact tandem repeat-variable number of tandem repeats) typing is insufficient for strain differentiation, due to a common ETR-A to E profile (42435). This leads to the false clustering in molecular epidemiological studies, especially in the regions of predominance of the W-Beijing family. In this study, we searched for VNTR loci with a high evolutionary rate of polymorphism in the W-Beijing genome. Here we further evaluated VNTR typing on a set of 99 Mycobacterium tuberculosis clinical isolates and reference strains. These isolates were characterized and classified into several genotype families based on three ETR loci (A, C, E) and eight additional loci [previously described as QUB (Queen's University Belfast) or MIRU (Mycobacterial Interspersed Repetitive Units) or Mtubs]. Ninety-nine strains were divided into 74 VNTR-types, 51 isolates of the W-Beijing family identified by IS6110 RFLP-typing (the restriction fragment length polymorphism-typing) and/or spoligotyping were subdivided into 30 VNTR-types. HGDI (the Hunter-Gaston discriminatory index) for all studied loci was close to that of IS6110 RFLP typing, a 'gold standard' method for subtyping M. tuberculosis complex strains. The QUB 26 and QUB 18 loci located in the PPE genes were highly polymorphic and more discriminative than other loci (HGDI is 0.8). Statistically significant increase of tandem repeats number in loci ETR-A, -E, QUB 26, QUB 18, QUB 11B, Mtub21 was revealed in the W-Beijing group compared to genetically divergent non-W-Beijing strains. Thirty-six isolates were subjected to IS6110 RFLP typing. The congruence between results of the IS6110 RFLP typing and 11-loci VNTR typing was estimated on 23 isolates of the W-Beijing family. These isolates were subdivided into 9 IS6110-RFLP types and 13 VNTR types. The poor

Mosaic tetracycline resistance determinants are a recently discovered class of hybrids of ribosomal protection tet genes. They may show different patterns of mosaicism, but their final size has remained unaltered. Initially thought to be confined to a small group of anaerobic bacteria, mosaic tet genes were then found to be widespread. In the genus Streptococcus, a mosaic tet gene [tet(O/W/32/O)] was first discovered in Streptococcus suis, an emerging drug-resistant pig and human pathogen. In this study, we report the molecular characterization of a tet(O/W/32/O) gene-carrying mobile element from an S. suis isolate. tet(O/W/32/O) was detected, in tandem with tet(40), in a circular 14,741-bp genetic element (39.1% G+C; 17 open reading frames [ORFs] identified). The novel element, which we designated 15K, also carried the macrolide resistance determinant erm(B) and an aminoglycoside resistance four-gene cluster including aadE (streptomycin) and aphA (kanamycin). 15K appeared to be an unstable genetic element that, in the absence of recombinases, is capable of undergoing spontaneous excision under standard growth conditions. In the integrated form, 15K was found inside a 54,879-bp integrative and conjugative element (ICE) (50.5% G+C; 55 ORFs), which we designated ICESsu32457. An ∼1.3-kb segment that apparently served as the att site for excision of the unstable 15K element was identified. The novel ICE was transferable at high frequency to recipients from pathogenic Streptococcus species (S. suis, Streptococcus pyogenes, Streptococcus pneumoniae, and Streptococcus agalactiae), suggesting that the multiresistance 15K element can successfully spread within streptococcal populations.

Interstitial-mediated diffusion and clustering for transmutation elements Re and Os precipitation in W

Under high energy (14 eV) neutrons irradiation in nuclear fusion devoices, tungsten (W) will undergo transmutation to its near-neighbors in the periodic table, such as rhenium (Re), osmium (Os), etc. The transmutation elements Re and Os will precipitate and form new Re/Os-rich phase, and further significantly degrade the mechanical properties of W. Here, we have investigated the mechanism for the irradiation-induced Re/Os clustering in W using the first-principles method and thermodynamic models. It is found that there is strong attraction between Re/Os and self-interstitial atom (SIA) in W. The SIA can be easily trapped by Re/Os once overcoming a low energy barrier, and form W-Re/Os complex dumbbell. The diffusion energy barrier of W-Re/Os is much lower than that of Re/Os diffusing via mono-vacancy or even vacancy clusters. Further, the W-Re/Os can be easily trapped by the substitutional Re/Os atoms, and form high stable Re-Re/Os-Os dumbbell structure. Most importantly, the Re-Re/Os-Os dumbbell can serve as trapping centre for subsequent interstitial-Re/Os, leading to the growth of Re/Os-rich clusters in W. Our finding suggests an interstitial-mediated mechanism for the irradiation-induced Re/Os clustering in W.

A determination of the single W Spin Density Matrix (SDM) elements in the reaction e+e- -> W+W- -> l nu q qbar (l=e/mu) is reported at centre-of-mass energies between 189 and 209 GeV. The data sample used corresponds to an integrated luminosity of 520 pb^{-1} taken by DELPHI between 1998 and 2000. The single W SDM elements, rho_{tau tau'}^{W+-} (tau,tau' = +/-1 or 0), are determined as a function of the W- production angle with respect to the e- beam direction and are obtained from measurements of the W decay products by the application of suitable projection operators, Lambda_{tau tau'}, which assume the V-A coupling of the W boson to fermions. The measured SDM elements are used to obtain the fraction of longitudinally polarised Ws, with the result: sigma_L/sigma_tot = 24.9 +/- 4.5(stat) +/- 2.2(syst) % at a mean energy of 198 GeV. The SDM elements are also used to determine the Triple Gauge Couplings Delta g_1^Z, Delta kappa_gamma, lambda_gamma and g_4^Z, ~kappa_Z and ~lambda_Z. For the CP-violating couplin...

The highly heat-loaded area of the target plates of the WENDELSTEIN 7-X (W7-X) divertor is formed by 890 water-cooled target elements (TEs). This surface is designed to sustain a maximum stationary heat flux of 10 MW/m 2 and to remove a maximum power of 100 kW per element. Flat tiles made of CFC Sepcarb(r) NB31 are bonded to a CuCrZr heat sink. This joint is manufactured in two stages. In the first step, an OFHC copper interlayer is cast onto the tile by active metal casting (AMC(r)). At this stage, the joint copper-CFC is inspected by X-ray and lock-in thermography. In the second step, the AMC(r)-NB31 tiles are joined to CuCrZr. Two technologies have been investigated: electron beam welding (EBW) and hot isostatic pressing (HIP). The joint copper-CuCrZr is examined by ultrasonic method. At the end of the fabrication, the bond between the heat sink and the CFC tiles is inspected by thermography methods. The produced CFC NB31 material for W7-X showed a large scatter in the tensile strength in the ex-pitch direction in the range of 50 - 110 MPa. Pre-series TEs have been manufactured to qualify the design, the fabrication, the relevant non-destructive examinations (NDEs) and the delivered CFC for the serial production. The whole manufacturing route is validated if the delivered elements withstand operating conditions similar to those in W7-X in the high heat flux (HHF) test facility GLADIS without degradation of performance and integrity. HHF tests did not show any effect that could be attributed to the CFC grade or to the joining method. The HHF test results exhibited a high percentage of defective tiles, indicated by hot spots at the border of the CFC surface. Visual inspections after HHF tests have mostly correlated these spots to the initiation and /or propagation of cracks at the lateral edge of the tiles in CFC at the interface CFC-copper. The pre-series activities have been extended to reduce the stresses at the critical AMC(r) interface. By means of

Full Text Available Abstract Background Human endogenous retroviruses (HERVs comprise a large class of repetitive retroelements. Most HERVs are ancient and invaded our genome at least 25 million years ago, except for the evolutionary young HERV-K group. The far majority of the encoded genes are degenerate due to mutational decay and only a few non-HERV-K loci are known to retain intact reading frames. Additional intact HERV genes may exist, since retroviral reading frames have not been systematically annotated on a genome-wide scale. Results By clustering of hits from multiple BLAST searches using known retroviral sequences we have mapped 1.1% of the human genome as retrovirus related. The coding potential of all identified HERV regions were analyzed by annotating viral open reading frames (vORFs and we report 7836 loci as verified by protein homology criteria. Among 59 intact or almost-intact viral polyproteins scattered around the human genome we have found 29 envelope genes including two novel gammaretroviral types. One encodes a protein similar to a recently discovered zebrafish retrovirus (ZFERV while another shows partial, C-terminal, homology to Syncytin (HERV-W/FRD. Conclusions This compilation of HERV sequences and their coding potential provide a useful tool for pursuing functional analysis such as RNA expression profiling and effects of viral proteins, which may, in turn, reveal a role for HERVs in human health and disease.

We present libvdwxc, a general library for evaluating the energy and potential for the family of vdW-DF exchange-correlation functionals. libvdwxc is written in C and provides an efficient implementation of the vdW-DF method and can be interfaced with various general-purpose DFT codes. Currently, the Gpaw and Octopus codes implement interfaces to libvdwxc. The present implementation emphasizes scalability and parallel performance, and thereby enables ab initio calculations of nanometer-scale complexes. The numerical accuracy is benchmarked on the S22 test set whereas parallel performance is benchmarked on ligand-protected gold nanoparticles ({{Au}}144{({{SC}}11{{NH}}25)}60) up to 9696 atoms.

The chronic shortage of human donor organs and tissues for allotransplantation could be relieved if clinical xenotransplantation were to become a viable clinical therapy. Balanced against the benefits of xenotransplantation are the possible consequences of zoonotic infections, and in particular, infection by porcine endogenous retrovirus (PERV). An often-proclaimed risk of PERV infection is the possible recombination of PERV with human endogenous retroviruses (HERV) . To address this issue, we examined the potential for HERV sequences to be cross-packaged into PERV particles produced from infected human 293 cells. Although HERV-K, W, E, R, and ERV-9 RNA transcripts are expressed in 293 cells, we did not detect cross-packaging of any of these HERV groups. Quantitative analysis indicated that less than approximately 1 in 10 4 -10 7 PERV particles might contain HERV sequences. In comparison, we found that murine leukemia virus (MLV)-based vector transcripts were cross-packaged at a rate of approximately one copy in 10 4 PERV particles. Our results indicate that the potential for recombination of PERV and HERV sequences is low and that novel viruses generated by this mechanism are unlikely to represent a significant risk for xenotransplantation

Full Text Available Purpose. To investigate genetic and clinical features of patients with rhodopsin (RHO mutations in two Japanese families with autosomal dominant retinitis pigmentosa (adRP. Methods. Whole-exome sequence analysis was performed in ten adRP families. Identified RHO mutations for the cosegregation analysis were confirmed by Sanger sequencing. Ophthalmic examinations were performed to evaluate the RP phenotypes. The impact of the RHO mutation on the rhodopsin conformation was examined by molecular modeling analysis. Results. In two adRP families, we identified two RHO mutations (c.377G>T (p.W126L and c.1036G>C (p.A346P, one of which was novel. Complete cosegregation was confirmed for each mutation exhibiting the RP phenotype in both families. Molecular modeling predicted that the novel mutation (p.W126L might impair rhodopsin function by affecting its conformational transition in the light-adapted form. Clinical phenotypes showed that patients with p.W126L exhibited sector RP, whereas patients with p.A346P exhibited classic RP. Conclusions. Our findings demonstrated that the novel mutation (p.W126L may be associated with the phenotype of sector RP. Identification of RHO mutations is a very useful tool for predicting disease severity and providing precise genetic counseling.

In a recent study we considered W{sub 3} Toda 4-point functions that involve matrix elements of a primary field with the highest-weight in the adjoint representation of sl{sub 3}. We generalize this result by considering a semi-degenerate primary field, which has one null vector at level two. We obtain a sixth-order Fuchsian differential equation for the conformal blocks. We discuss the presence of multiplicities, the matrix elements and the fusion rules.

Lichen planus (LP) is a common inflammatory skin disease of unknown etiology. Reports of a common transactivation of quiescent human endogenous retroviruses (HERVs) support the connection of viruses to the disease. HERVs are ancient retroviral sequences in the human genome and their transcription is often deregulated in cancer and autoimmune diseases. We explored the transcriptional activity of HERV sequences as well as the antiviral restriction factor and interferon-inducible genes in the skin from LP patients and healthy control (HC) donors. The study included 13 skin biopsies from patients with LP and 12 controls. Real-time PCR assay identified significant decrease in the HERV-K gag and env mRNA expression levels in LP subjects, when compared to control group. The expressions of HERV-K18 and HERV-W env were also inhibited in the skin of LP patients. We observed a strong correlation between HERV-K gag with other HERV sequences, regardless the down-modulation of transcripts levels in LP group. In contrast, a significant up-regulation of the cytidine deaminase APOBEC 3G (apolipoprotein B mRNA-editing), and the GTPase MxA (Myxovirus resistance A) mRNA expression level was identified in the LP skin specimens. Other transcript expressions, such as the master regulator of type I interferon-dependent immune responses, STING (stimulator of interferon genes) and IRF-7 (interferon regulatory factor 7), IFN-β and the inflammassome NALP3, had increased levels in LP, when compared to HC group. Our study suggests that interferon-inducible factors, in addition to their role in innate immunity against exogenous pathogens, contribute to the immune control of HERVs. Evaluation of the balance between HERV and interferon-inducible factor expression could possibly contribute to surveillance of inflammatory/malignant status of skin diseases.

The regulation of gene expression involves a multifarious regulatory system. Each gene contains a unique combination of cis-acting regulatory sequence elements in the 5' regulatory region that determines its temporal and spatial expression. Cis-acting regulatory elements are essential transcriptional gene regulatory units; they control many biological processes and stress responses. Thus a full understanding of the transcriptional gene regulation system will depend on successful functional analyses of cis-acting elements. Cis-acting regulatory elements present within the 5' regulatory region of the sucrose transporter gene families in rice (Oryza sativa Japonica cultivar-group) and Arabidopsis thaliana, were identified using a bioinformatics approach. The possible cis-acting regulatory elements were predicted by scanning 1.5kbp of 5' regulatory regions of the sucrose transporter genes translational start sites, using Plant CARE, PLACE and Genomatix Matinspector professional databases. Several cis-acting regulatory elements that are associated with plant development, plant hormonal regulation and stress response were identified, and were present in varying frequencies within the 1.5kbp of 5' regulatory region, among which are; A-box, RY, CAT, Pyrimidine-box, Sucrose-box, ABRE, ARF, ERE, GARE, Me-JA, ARE, DRE, GA-motif, GATA, GT-1, MYC, MYB, W-box, and I-box. This result reveals the probable cis-acting regulatory elements that possibly are involved in the expression and regulation of sucrose transporter gene families in rice and Arabidopsis thaliana during cellular development or environmental stress conditions.

Unitary W-algebras and three-dimensional higher spin gravities with spin one symmetry

International Nuclear Information System (INIS)

2014-01-01

We investigate whether there are unitary families of W-algebras with spin one fields in the natural example of the Feigin-Semikhatov W_n"("2")-algebra. This algebra is conjecturally a quantum Hamiltonian reduction corresponding to a non-principal nilpotent element. We conjecture that this algebra admits a unitary real form for even n. Our main result is that this conjecture is consistent with the known part of the operator product algebra, and especially it is true for n=2 and n=4. Moreover, we find certain ranges of allowed levels where a positive definite inner product is possible. We also find a unitary conformal field theory for every even n at the special level k+n=(n+1)/(n−1). At these points, the W_n"("2")-algebra is nothing but a compactified free boson. This family of W-algebras admits an ’t Hooft limit. Further, in the case of n=4, we reproduce the algebra from the higher spin gravity point of view. In general, gravity computations allow us to reproduce some leading coefficients of the operator product.

BoS: a large and diverse family of short interspersed elements (SINEs) in Brassica oleracea.

Zhang, Xiaoyu; Wessler, Susan R

2005-05-01

Short interspersed elements (SINEs) are nonautonomous non-LTR retrotransposons that populate eukaryotic genomes. Numerous SINE families have been identified in animals, whereas only a few have been described in plants. Here we describe a new family of SINEs, named BoS, that is widespread in Brassicaceae and present at approximately 2000 copies in Brassica oleracea. In addition to sharing a modular structure and target site preference with previously described SINEs, BoS elements have several unusual features. First, the head regions of BoS RNAs can adopt a distinct hairpin-like secondary structure. Second, with 15 distinct subfamilies, BoS represents one of the most diverse SINE families described to date. Third, several of the subfamilies have a mosaic structure that has arisen through the exchange of sequences between existing subfamilies, possibly during retrotransposition. Analysis of BoS subfamilies indicate that they were active during various time periods through the evolution of Brassicaceae and that active elements may still reside in some Brassica species. As such, BoS elements may be a valuable tool as phylogenetic makers for resolving outstanding issues in the evolution of species in the Brassicaceae family.

Highlights: • The Wendelstein 7-X surface of the actively cooled divertor is built up of 890 individually 3D machined target elements. • To date 300 target elements have been 3D machined with an accuracy of ±0.015 mm. • Copper discovered on the surface of few elements is no risk to operation. - Abstract: The high heat flux (HHF) divertor of W7-X consists of 100 target modules assembled from 890 actively water-cooled target elements protected with CFC tiles. The divertor surface will be built up of individually 3D machined target elements with 89 individual element types. To date 300 of the 890 target elements have been 3D machined with a very good accuracy. To achieve this successful result, a prototyping phase has been conducted to qualify the manufacturing route and to define the acceptance criteria with measures taken to minimize the risk of unacceptable damage during the manufacturing. After the 3D-machining, during the incoming inspection, copper infiltration from the interface between the CFC tiles and the CuCrZr heat sink to the plasma facing surface was detected in a small number of elements.

Angelopoulos treated myth as a set of archetypical situations and patterns of conduct constantly reproduced in the history of the world. He intertwined elements of classical stories with the history of Greece and the Byzantine tradition, thus showing their universal character. In The travelling players, Angelopoulos used the story of betrayed and murdered Agamemnon, who is avenged by his children: Orestes and Electra, but he moved it into modern times, setting the film in Greece of the 1940s and 1950s. The myth is reproduced with modulations: the most important events take place as a result of interventions of History, not fate or decisions of the gods. Moreover, the characters’ conflicts are enriched with a political dimension, as Angelopolous portrays the discord between their ideological stances. But the members of the acting company are as helpless in the face of events as the family of the king of Argos.   Orestes bojownikiem ruchu oporu, czyli mit Atrydów w filmie Podróż komediantów Theo Angelopoulosa Artykuł jest analizą sposobu wykorzystania przez Theo Angelopoulosa mitu Atrydów w filmie Podróż komediantów (1975 w kontekście dokonanej przez niego interpretacji zjawiska mitu.

This study aims to evaluate the distribution of K, Rb and Cs in leaves of trees of the Atlantic Forest through studies of correlation between the chemical elements. For this, we used the Instrumental Neutron Activation Analysis for the quantification of the chemical elements. The concentration ranges found were 6700-24000 mg / kg for K, 16 to 72mg / kg for Rb and 0.08 to 0,92mg / kg for Cs. As Rb has chemical similarity to K, is easily absorbed by plants, leading to a high value (0.9) of the Pearson correlation. For the correlation between K and Cs, no significant values were detected except for some species of the Myrtaceae family. However, average correlations (0.6 < r <0.8) between Rb-Cs were obtained for seven plant species of different families. The absence of a specific pattern using of K, Rb and Cs by plants showed great complexity in the distribution of chemical elements in the ecosystem

Full text of publication follows: The target elements of Wendelstein 7-X (W7-X) divertor are designed to sustain a stationary heat flux of 10 MW/m 2 and to remove a maximum power load up to 100 kW. The plasma-facing material is made of CFC NB31 flat tiles bonded to a CuCrZr copper alloy water-cooled heat sink. Before launching the serial fabrication, pre-series activities aimed at qualifying the design, the manufacturing route, the relevant non-destructive examination (NDE) methods, and at defining the acceptance criteria for the serial production. High heat flux (HHF) testing is the central activity of this qualification phase and represents a fundamental tool to predict 'critical' defects assembling. Within the framework of this qualification activity, the reception tests performed in the transient infrared thermography test bed SATIR at CEA-Cadarache and HHF testing carried out in the ion beam facility GLADIS at IPP-Garching, exhibited some tiles with thermal inhomogeneities, which initiated and developed during high heat flux testing. Hence, studies were launched in order to better understand this behaviour during cyclic heat loading. This post testing examination was mainly focused on the interface between CFC flat tiles and CuCrZr heat sink to improve if necessary the current design. HHF thermal cycling tests at ∼10 MW/m 2 for 10 s pulse duration each, allowed to assess the performances of target elements and showed some tiles with hot spots close to the edge (stable or progressing). Finally, after the HHF experimental campaign, a comprehensive analysis of some tested elements was carried out by means of infrared thermography inspection SATIR and metallographic examinations. Afterwards correlations between the non destructive SATIR inspection, HHF testing GLADIS and metallographic observation were investigated to assess damage detection, to analyse defect propagation, and to adjust the acceptance criteria valuable for the serial production.

The present work concern the amorphisation process induced by mechanical alloying in the NiW, NiMo and MoW systems. The alloys chosen combine a group of transition elements varying from very similar atomic radius and electronic valences (MoW) to different ones (NiW and NiMo). The three systems achieved an amorphous state after 50 h of milling. The mechanism of amorphisation proposed for NiW and NiMo was the combined effect of an excess concentration of the solute atoms entering into the structure of one of the elements and a critical concentration of defects. Continuous formation of an amorphous phase at the interface of the crystalline phase was observed during the process. MoW seems to amorphize by continuous reduction of grain size down to a critical value where the amorphisation takes place

Full Text Available The family is the basic cell of every society and is therefore a key element in the creation and existence of every state across the world. At the beginning of the 21st century, more than ever the institution of the family is in crisis, characterized by a particularly low interest in the state of marriage and a high divorce rate among young couples. The main negative elements acting on the existence of families in the Slovak Republic include in particular the low social and economic status of the population, the expansion of narcotic drugs and psychotropic substances, some family members moving to work elsewhere in Slovakia or abroad and also the gradual drifting apart of young families from parents and grandparents. If the crisis of social units has violated the harmony and adjourned original morality and ethics, we can look at the initial violence and many serious conflicts. In this paper we deal with the family in terms of key features. Subsequently, we analyze the harmonious family, the disharmonic family, friends and functionality. Further emphasis is on intergenerational solidarity in the social unit, which is essential to maintain and develop the company. Finally, it should be added that at present there are different views on the form of the family, including social and legislative form of homosexual social units. It should be noted that in the Slovak society the dominant view is on maintaining the traditional family.

ABFs, a family of ABA-responsive element binding factors.

Abscisic acid (ABA) plays an important role in environmental stress responses of higher plants during vegetative growth. One of the ABA-mediated responses is the induced expression of a large number of genes, which is mediated by cis-regulatory elements known as abscisic acid-responsive elements (ABREs). Although a number of ABRE binding transcription factors have been known, they are not specifically from vegetative tissues under induced conditions. Considering the tissue specificity of ABA signaling pathways, factors mediating ABA-dependent stress responses during vegetative growth phase may thus have been unidentified so far. Here, we report a family of ABRE binding factors isolated from young Arabidopsis plants under stress conditions. The factors, isolated by a yeast one-hybrid system using a prototypical ABRE and named as ABFs (ABRE binding factors) belong to a distinct subfamily of bZIP proteins. Binding site selection assay performed with one ABF showed that its preferred binding site is the strong ABRE, CACGTGGC. ABFs can transactivate an ABRE-containing reporter gene in yeast. Expression of ABFs is induced by ABA and various stress treatments, whereas their induction patterns are different from one another. Thus, a new family of ABRE binding factors indeed exists that have the potential to activate a large number of ABA/stress-responsive genes in Arabidopsis.

In practical applications PHOTOS Monte Carlo is often used for simulation of QED effects in decay of intermediate particles and resonances. Generated in such a way that samples of events cover the whole bremsstrahlung phase space. With the help of selection cuts, experimental acceptance can be then taken into account. The program is based on exact multiphoton phase space. To evaluate the program precision it is necessary to control its matrix element. Generally it is obtained using iteration of the universal multidimensional kernel. In some cases it is however obtained from the exact first order matrix element. Then, as a consequence, all terms necessary for non-leading logarithms are taken into account. In the present paper we will focus on the decays W -> l nu and gamma^* -> pi^+ pi^-. The Born level cross sections for both processes approach zero in some points of the phase space. Process dependent, compensating weight is constructed to implement exact matrix element, but it will be recommended for use onl...

W-geometry

The geometric structure of theories with gauge fields of spins two and higher should involve a higher spin generalisation of Riemannian geometry. Such geometries are discussed and the case of W ∝ -gravity is analysed in detail. While the gauge group for gravity in d dimensions is the diffeomorphism group of the space-time, the gauge group for a certain W-gravity theory (which is W ∝ -gravity in the case d=2) is the group of symplectic diffeomorphisms of the cotangent bundle of the space-time. Gauge transformations for W-gravity gauge fields are given by requiring the invariance of a generalised line element. Densities exist and can be constructed from the line element (generalising √detg μν ) only if d=1 or d=2, so that only for d=1,2 can actions be constructed. These two cases and the corresponding W-gravity actions are considered in detail. In d=2, the gauge group is effectively only a subgroup of the symplectic diffeomorphisms group. Some of the constraints that arise for d=2 are similar to equations arising in the study of self-dual four-dimensional geometries and can be analysed using twistor methods, allowing contact to be made with other formulations of W-gravity. While the twistor transform for self-dual spaces with one Killing vector reduces to a Legendre transform, that for two Killing vectors gives a generalisation of the Legendre transform. (orig.)

The development of actively cooled plasma-facing components (PFC) represents one of fusion's most challenging engineering efforts. In this frame, a high-quality bonding between the refractory armour and the heat sink is essential to ensure the heat removal capability and the thermal performances of PFC. Experience gained during manufacturing of Tore Supra actively cooled PFC led to the establishment of a qualification methodology and provided a large experience of acceptance criteria using an active infrared thermography (systeme d'acquisition de traitement infra-rouge, SATIR). This paper presents the application of this qualification process to the W7-X pre-series components, with the objective of assessing and defining workable acceptance criteria that enable reliable predictions of performance at the nominal heat flux requirements in W7-X. Finally, to check the reliability of the non-destructive examination (NDE) method by transient infrared thermography, the newly defined acceptance criteria were applied to W7-X pre-series target elements (batch no. 3). The SATIR results, benchmarked with HHF tests performed on the GLADIS ion beam facility were discussed to assess the ability to detect critical defects at the interface between tiles and heat sink

Schizophrenia is a complex biopsychosocial condition in which expressed emotion in family members is a robust predictor of relapse. Not surprisingly, family interventions are remarkably effective and thus recommended in current treatment guidelines. Their key elements seem to be common therapeutic factors, followed by education and coping skills training. However, few studies have explored these key elements and the process of the intervention itself. We conducted a qualitative and quantitative analysis of the records from a pioneering family intervention trial addressing expressed emotion, published by Leff and colleagues four decades ago. Records were analyzed into categories and data explored using descriptive statistics. This was complemented by a narrative evaluation using an inductive approach based on emotional markers and markers of change. The most used strategies in the intervention were addressing needs, followed by coping skills enhancement, advice, and emotional support. Dealing with overinvolvement and reframing were the next most frequent. Single-family home sessions seemed to augment the therapeutic work conducted in family groups. Overall the intervention seemed to promote cognitive and emotional change in the participants, and therapists were sensitive to the emotional trajectory of each subject. On the basis of our findings, we developed a longitudinal framework for better understanding the process of this treatment approach. © 2016 Family Process Institute.

Mourning is predominantly understood as an emotional process caused by the loss of a beloved other. This assumption is challenged by this article on Hervé Guibert’s 1990 documentary La Pudeur ou l’impudeur in which the author and photographer represents his physical and emotional suffering through the last stages of AIDS. The article explores this suffering via the idea of ‘self mourning’ which denotes the subject’s reflection on his own mortality and which as the author proposes is part of e...

The target elements of the WENDELSTEIN 7-X (W7-X) divertor are designed to sustain a stationary heat flux of 10 MW/m 2 and to remove a maximum power of 100 kW. CFC Sepcarb NB31 tiles are bonded to a water-cooled CuCrZr heat sink in two steps: active metal casting (AMC) of an AMC -copper interlayer to CFC tiles, electron beam welding (EBW) or hot isostatic pressing (HIP) of the AMC -NB31 tiles to CuCrZr. The fabrication of the whole amount of CFC NB31 has been completed. The key target of the pre-series phase is the qualification of this bond based on a series of examinations. The introduction of silicon during the AMC process significantly improved the strength of the joint between CFC and AMC -copper. The strength of the bond is preserved after either EBW or HIP processes. High heat flux testing carried out in the ion beam facility GLADIS exhibited a too high percentage of defective tiles. Pre-series activities have been extended to reduce the stress concentration at the interface between tiles and heat sink by optimizing the design

2016-01-01

In this study we developed a Fast Healthcare Interoperability Resources (FHIR) profile to support exchanging a full pedigree based family health history (FHH) information across multiple systems and applications used by clinicians, patients, and researchers. We used previously developed clinical element models (CEMs) that are capable of representing the FHH information, and derived essential data elements including attributes, constraints, and value sets. We analyzed gaps between the FHH CEM elements and existing FHIR resources. Based on the analysis, we developed a profile that consists of 1) FHIR resources for essential FHH data elements, 2) extensions for additional elements that were not covered by the resources, and 3) a structured definition to integrate patient and family member information in a FHIR message. We implemented the profile using an open-source based FHIR framework and validated it using patient-entered FHH data that was captured through a locally developed FHH tool.

The behaviour of the elements Ni, Co, Cu, Pb, Zn, Au, Ag, Mo, Sn, W and U in the magmatic, hydrothermal, sedimentary and weathering environments

1978-01-01

In the last two decades much has been published on the behaviour of certain elements in the magmatic, hydrothermal, sedimentary and weathering environments, but the information is scattered throughout the literature. This situation prompted the present study on the elements Ni, Co, Cu, Pb, Zn, Au, Ag, Mo, Sn, W and U. The behaviour of the elements Ni, Cu, Pb, Zn, Au, Sn, W and U has been studied experimentally in some depth. Ag has been moderately studied, but there is very little information about Co and Mo. Studies on the complexes formed by the elements within the hydrothermal and aqueous environment are often inconclusive and controversial, but conclusions are drawn as to the more likely complexes formed. A genetic classification of ore deposits is used as a framework for the discussion. The source of the elements is regarded as being the mantle, and therefore discussion on other possible sources is beyond the scope of this dissertation. The crystal chemistry and geochemistry of the elements are presented and the essay concludes with a discussion on the elements within their depositional environments

Familial isolated pituitary adenomas (FIPA) constitute 2-3% of pituitary tumours. AIP is the most commonly mutated gene in FIPA. We herein report a novel germline mutation of the AIP gene in a family with FIPA. We present two patients, a father and his 12-year-old daughter, diagnosed clinically and using laboratory measures with acromegaly-gigantism. Both underwent transsphenoidal hypophyseal surgery for macroadenomas. We initially detected a novel heterozygous germline AIP mutation, c.836G>A (p.W279*), in the father's DNA. We then found the same mutation in his affected daughter. Pituitary adenomas associated with AIP mutations mostly present as FIPA (68%) at an early age (78% occur at treatment success, and genetic counseling.

Sieve element occlusion (SEO) genes encoding forisome subunits have been identified in Medicago truncatula and other legumes. Forisomes are structural phloem proteins uniquely found in Fabaceae sieve elements. They undergo a reversible conformational change after wounding, from a condensed to a dispersed state, thereby blocking sieve tube translocation and preventing the loss of photoassimilates. Recently, we identified SEO genes in several non-Fabaceae plants (lacking forisomes) and concluded that they most probably encode conventional non-forisome P-proteins. Molecular and phylogenetic analysis of the SEO gene family has identified domains that are characteristic for SEO proteins. Here, we extended our phylogenetic analysis by including additional SEO genes from several diverse species based on recently published genomic data. Our results strengthen the original assumption that SEO genes seem to be widespread in dicotyledonous angiosperms, and further underline the divergent evolution of SEO genes within the Fabaceae.

Full Text Available Transposons are ubiquitous genomic components that play pivotal roles in plant gene and genome evolution. We analyzed two genome sequences of common bean (Phaseolus vulgaris and identified a new CACTA transposon family named pvCACTA1. The family is extremely abundant, as more than 12,000 pvCACTA1 elements were found. To our knowledge, this is the most abundant CACTA family reported thus far. The computational and fluorescence in situ hybridization (FISH analyses indicated that the pvCACTA1 elements were concentrated in terminal regions of chromosomes and frequently generated AT-rich 3 bp target site duplications (TSD, WWW, W is A or T. Comparative analysis of the common bean genomes from two domesticated genetic pools revealed that new insertions or excisions of pvCACTA1 elements occurred after the divergence of the two common beans, and some of the polymorphic elements likely resulted in variation in gene sequences. pvCACTA1 elements were detected in related species but not outside the Phaseolus genus. We calculated the molecular evolutionary rate of pvCACTA1 transposons using orthologous elements that indicated that most transposition events likely occurred before the divergence of the two gene pools. These results reveal unique features and evolution of this new transposon family in the common bean genome.

THE ROLE OF EPSTEIN-BARR VIRUS AND HUMAN ENDOGENOUS RETROVIRUSES IN THE PATHOGENESIS OF MULTIPLE SCLEROSIS

peripheral blood mononuclear cells culture of MSRV-positive individuals, expression of MSRV was activated by the action of pro-inflammatory cytokines such as TNF-α, IL-6, and IFN-γ, and significantly decreased by IFN-β. At the brain level, HERV-Wenv activates Toll-like receptors (TLR4 of oligodendroglial precursor cells, which results in the production of pro-inflammatory cytokines as well as inducible nitric oxide synthase (iNOS, and a decrease in myelin protein expression. Within chronic brain lesions in MS, HERV-Wenv was detected in microglia / macrophages near TLR4-positive oligodendroglial precursor cells. Immunohistochemical detection of HERV-Wenv protein in postmortem brain samples of MS patients showed its elevated levels only in active lesions in astrocytes and microglia, and the intensity of staining correlated with the degree of active demyelination and inflammation. Thus, EBV infection and activation of retroviruses are considered as important elements in the pathogenesis of MS. Within the framework of the "viral hypothesis", the most important tasks are the verification of data indicating the possible etiological role of EBV, the study of the pathogenetic mechanisms associated with MSRV/HERV-W at different stages of MS development, as well as the identification of immunological and genetic factors associated with the defective control of EBV-infected B cells and, as a result, their migration and accumulation in the CNS. Thus, EBV infection and activation of retroviruses are considered as important factors in the pathogenesis of MS. Late EBV infection may be the initiating trigger of the pathological process leading to the development of MS years later, and HERV-W / MSRV affect as active cofactors of the neuropathogenesis of the MS accompanying the course of the disease. The aim of the review was to consider the latest evidence of possible mechanisms of the involvement of EBV and human endogenous retroviruses in the pathogenesis of multiple sclerosis.

Short interspersed nuclear elements (SINEs) are non-autonomous transposable elements which are propagated by retrotransposition and constitute an inherent part of the genome of most eukaryotic species. Knowledge of heterogeneous and highly abundant SINEs is crucial for de novo (or improvement of) annotation of whole genome sequences. We scanned Poaceae genome sequences of six important cereals (Oryza sativa, Triticum aestivum, Hordeum vulgare, Panicum virgatum, Sorghum bicolor, Zea mays) and Brachypodium distachyon to examine the diversity and evolution of SINE populations. We comparatively analyzed the structural features, distribution, evolutionary relation and abundance of 32 SINE families and subfamilies within grasses, comprising 11 052 individual copies. The investigation of activity profiles within the Poaceae provides insights into their species-specific diversification and amplification. We found that Poaceae SINEs (PoaS) fall into two length categories: simple SINEs of up to 180 bp and dimeric SINEs larger than 240 bp. Detailed analysis at the nucleotide level revealed that multimerization of related and unrelated SINE copies is an important evolutionary mechanism of SINE formation. We conclude that PoaS families diversify by massive reshuffling between SINE families, likely caused by insertion of truncated copies, and provide a model for this evolutionary scenario. Twenty-eight of 32 PoaS families and subfamilies show significant conservation, in particular either in the 5' or 3' regions, across Poaceae species and share large sequence stretches with one or more other PoaS families. © 2017 The Authors The Plant Journal © 2017 John Wiley & Sons Ltd.

Effects of alloying elements (Mn, Co, Al, W, Sn, B, C and S) on biodegradability and in vitro biocompatibility of pure iron.

2011-03-01

Pure iron was determined to be a valid candidate material for biodegradable metallic stents in recent animal tests; however, a much faster degradation rate in physiological environments was desired. C, Mn, Si, P, S, B, Cr, Ni, Pb, Mo, Al, Ti, Cu, Co, V and W are common alloying elements in industrial steels, with Cr, Ni, Mo, Cu, Ti, V and Si being acknowledged as beneficial in enhancing the corrosion resistance of iron. The purpose of the present work (using Fe-X binary alloy models) is to explore the effect of the remaining alloying elements (Mn, Co, Al, W, B, C and S) and one detrimental impurity element Sn on the biodegradability and biocompatibility of pure iron by scanning electron microscopy, X-ray diffraction, metallographic observation, tensile testing, microhardness testing, electrochemical testing, static (for 6 months) and dynamic (for 1 month with various dissolved oxygen concentrations) immersion testing, cytotoxicity testing, hemolysis and platelet adhesion testing. The results showed that the addition of all alloying elements except for Sn improved the mechanical properties of iron after rolling. Localized corrosion of Fe-X binary alloys was observed in both static and dynamic immersion tests. Except for the Fe-Mn alloy, which showed a significant decrease in corrosion rate, the other Fe-X binary alloy corrosion rates were close to that of pure iron. It was found that compared with pure iron all Fe-X binary alloys decreased the viability of the L929 cell line, none of experimental alloying elements significantly reduced the viability of vascular smooth muscle cells and all the elements except for Mn increased the viability of the ECV304 cell line. The hemolysis percentage of all Fe-X binary alloy models were less than 5%, and no sign of thrombogenicity was observed. In vitro corrosion and the biological behavior of these Fe-X binary alloys are discussed and a corresponding mechanism of corrosion of Fe-X binary alloys in Hank's solution proposed. As a

Full Text Available The concept of the family (social bond has not been explained and precisely defined so far. The most common definition is known as a dual character of human relationships. Cultural, economic, legal, religious and social factors in which a family lives, influence considerably the typical family bonds. Transformations of the bond in the 21st century family are caused by changes which have occurred and continuue to occur in the structure, functions and organization of the family live. A system of mutually connected elements of the upbringing process in the family, between which all kinds of dynamic associations and interactions are clearly visible. So we should pay our attention to transformations of the family bond in incessantly changing conditions. It is necessary especially in social, economic and cultural areas, where the role of the traditional family is becoming less important.

Two ABREs, two redundant root-specific and one W-box cis-acting elements are functional in the sunflower HAHB4 promoter.

Manavella, Pablo A; Dezar, Carlos A; Ariel, Federico D; Chan, Raquel L

HAHB4 is a sunflower gene encoding a homeodomain-leucine zipper (HD-Zip) transcription factor. It was previously demonstrated that this gene is regulated at the transcriptional level by several abiotic factors and hormones. A previous analysis in the PLACE database revealed the presence of four putative ABREs. In this work these four elements and also one W-box and two root-specific expression elements were characterized as functional. Site-directed mutagenesis on the promoter, stable transformation of Arabidopis plants as well as transient transformation of sunflower leaves, were performed. The analysis of the transformants was carried out by histochemistry and real time RT-PCR. The results indicate that just one ABRE out of the four is responsible for ABA, NaCl and drought regulation. However, NaCl induction occurs also by an additional ABA-independent way involving another two overlapped ABREs. On the other hand, it was determined that the W-box located 5' upstream is responsive to ethylene and only two root-specific expression elements, among the several detected, are functional but redundant. Conservation of molecular mechanisms between sunflower and Arabidopsis is strongly supported by this experimental work.

Full Text Available Wprowadzenie gimnazjum – jednego z elementów zmiany systemu edukacyjnego, dostosowującej go do ogólnych parametrów postfordowskiego kapitalizmu – wpłynęło na styl edukacyjny klasy ludowej w Polsce. Zmiany zachodzące w systemie od reformy w 1999 r., dotyczące ekonomizacji edukacji, parametryzacji i kwantyfikacji wyników edukacyjnych oraz wprowadzenia elementów gry rynkowej do zarządzania i finansowania szkół publicznych, przypominają procesy zachodzące od lat 80. XX w. w krajach zachodnich. Ich wpływ na styl życia klasy ludowej w Polsce wywołuje konsekwencje wynikające z lokalnej specyfiki. Artykuł opiera się na analizie 120 wywiadów pogłębionych przeprowadzonych w latach 2013–2014 z robotnikami, rolnikami i pracownikami fizycznymi w czterech regonach Polski oraz 60 wywiadów z przedstawicielami klasy średniej i wyższej z województwa warmińsko-mazurskiego. Wykazano, że charakterystyka poddanego prawom rynkowym systemu edukacyjnego jest najlepiej dostosowana do kultury klasy średniej, w związku z czym dzieci z rodzin o niższej pozycji społecznej mogą mieć trudności z funkcjonowaniem w takim systemie. Ustalenie to staje się podstawą do formułowania nowych propozycji teoretycznych i badawczych w obszarze badań edukacyjnych.

Full Text Available Elements of the Belarusian language in the Russian dialect used by the Old Believers living in the Suwałki-Augustów region The article deals with the Belarusian elements in the Russian dialect of the Old Believers living in Poland. The Old Believers arrived in Poland in the second half of the 18th century. At present they live in the Suwałki-Augustów region in the north-eastern Poland. They inhabit mostly two villages in the county of Suwałki, namely Gabowe Grądy and Bór, which are very close to each other, and three towns: Augustów, Suwałki and Sejny. The dialect used by the Polish Old Believers represents the western Central Great Russian dialects characterized by akanie, the so-called Pskov group. They share features which are typical of Pskov. The dialect was also influenced by other north-eastern Belarusian dialects, that is, the ones which were closest to the areas originally inhabited by Old Believers, who migrated in phases. After each phase, their dialect came to reflect some new linguistic influences. A large number of lexemes directly borrowed from Polish, or via the Belarusian language, are found in this dialect, which is also characterized by other features common in Belarusian dialects or the Bulgarian language. By way of illustration, they include the following features: the prosthetic j-, prosthetic v-, the occurrence of the endings –im and –ym in the case of singular masculine adjectives in the locative, promotion of the endings –i and –y in the case of the plural masculine and neutral nouns in the nominative, and the occurrence of lexemes borrowed from the Belarusian language.   Białoruskie elementy językowe w rosyjskiej gwarze staroobrzędowców mieszkających w regionie suwalsko-augustowskim Artykuł poświęcony jest problematyce białoruskich elementów językowych w rosyjskiej gwarze staroobrzędowców mieszkających w Polsce.

Full Text Available The Romanian communist leaders believed that, after centuries of ignorance and raisingchildren according to customs and habits, “family upbringing is in need of additional guidance”. According to Stearns “children had to be remade1 ” and the state pretended that it knew more about children’s needs that their own parents! More than in any other historical period the state substituted itself for the parents, through the school, children’s organizations and by indoctrinating the parents, using various guides and advice books written by the ideologists of the party, fully complying with communist ideals but less so with parenthood. The child is the object of state upbringing since “parents were not fully reliable for the task of raising their own children and they needed additional guidance”. The aim of this study is to reveal the massive intrusion of the state into family life, the taking-over of some roles specific to parents and grandparents – often by socialising children at very young ages – and the control that was reinforced in order to accomplish the requirements of the party. More than belonging to their parents, children were rather seen as belonging to the state and this brought half of a century of dualism between the old habits that the parents were used to and the new rules reinforced by the state. We shall stress the connexions between the proclamation of gender equality, mass schooling, family support measures for mothers and children and the characteristics of upbringing in the communist period

One of the aims of our research was to describe the upbringing by work in families living in towns and villages of lubelskie voivodship. It turned out that nearly every child has its own duties at home. At the same time, just a few percent of children seem to be overworked. The children do everyday activities (such as eating, dressing up, washing themselves etc. and help parents in everyday duties at home. The grandparents do not perform a big role in housework – neither as those that do it nor as people who need help. The housework is divided, to a high degree, into a male part and a female part. The division is also partly visible as far as children are concerned. In most families education (homework is more important than the help with housework. On the whole, we can say that most of the families demand from their children that they should take part in the housework in accordance with their age.

Redefinition and unification of the SXT/R391 family of integrative and conjugative elements.

Integrative and conjugative elements (ICEs) of the SXT/R391 family are key drivers of the spread of antibiotic resistance in Vibrio cholerae , the infectious agent of cholera, and other pathogenic bacteria. The SXT/R391 family of ICEs was defined based on the conservation of a core set of 52 genes and site-specific integration into the 5' end of the chromosomal gene prfC Hence, the integrase gene int has been intensively used as a marker to detect SXT/R391 ICEs in clinical isolates. ICEs sharing most core genes but differing by their integration site and integrase gene have been recently reported and excluded from the SXT/R391 family. Here we explored the prevalence and diversity of atypical ICEs in Genbank databases and their relationship with typical SXT/R391 ICEs. We found atypical ICEs in V. cholerae isolates that predate the emergence and expansion of typical SXT/R391 ICEs in the mid-1980s in seventh pandemic toxigenic V. cholerae O1 and O139 strains. Our analyses revealed that while atypical ICEs are not associated with antibiotic resistance genes, they often carry cation efflux pumps suggesting heavy metal resistance. Atypical ICEs constitute a polyphyletic group likely because of occasional recombination events with typical ICEs. Furthermore, we show that the alternative integration and excision genes of atypical ICEs remain under the control of SetCD, the main activator of the conjugative functions of SXT/R391 ICEs. Together these observations indicate that substitution of the integration/excision module and change of specificity of integration do not preclude atypical ICEs from inclusion into the SXT/R391 family. Importance Vibrio cholerae is the causative agent of cholera, an acute intestinal infection that remains to this day a world public health threat. Integrative and conjugative elements (ICEs) of the SXT/R391 family have played a major role in spreading antimicrobial resistance in seventh pandemic V. cholerae but also in several species of

Since 2009, legislation of the National School Feeding Program of Brazil (PNAE) institutionalizes its linkage with family farming as it establishes the requirement that at least 30% out of the total financial resources allocated by the federal government to the states and municipalities for school feeding must be used in the purchase of products directly from this sector. This study analyzes the process of drafting this legislation, focusing on the elements related to the procurement from family farming, through a historical contextualization, and it also presents a graphical representation with the main elements of this linkage: its objectives, target population, actions implemented and expected results. Actors involved with the drafting of the legislation were interviewed. The analyses show that the procurement from family farming is a far-reaching initiative in terms of the concept, execution and results. It has also showed that a strong articulation between the actors and institutions of the different sectors involved is critical to its success. The education, agriculture, planning, procurement and civil society sectors should work articulately at national, state and local level. The results of this study demonstrate that initiatives like this, of institutional procurement from family farming, which are currently being implemented in several countries, constitute as an important strategy of food and nutrition security, for the fulfillment of the human right to adequate food and the promotion of long-term sustainable development.

Measurements of the Ratio of W and Z Production and the W Boson Decay Width at CDF

Energy Technology Data Exchange (ETDEWEB)

Copic, Katherine Ann [Univ. of Michigan, Ann Arbor, MI (United States)

2007-03-01

We present a new method of measuring the ratio of W and Z production and de- cay (R) at the CDF experiment. We analyze 307 pb^-1 of proton-antiproton collisions at the Fermilab Tevatron center-of-mass energy of 1.96 TeV. A single sample containing both W and Z boson candidates is selected by requiring at least one high-energy electron in an event with low hadronic activity. We estimate that less than one percent of our sample is made up of background events after a cut on the recoil energy. A maximum likelihood fits is performed on the missing transverse energy spectrum of the events to determine the relative rates of W and Z production in the common sample. This ratio is defined as: R = Z · → Z Γ(W → £ν) 1 Γ(W ) Br(Z → ££) We have obtained the fi result using this method for the electron channel. R = 10.55 ± 0.09(stat) ± 0.12(syst) We then extract the Branching Ratio of W → £ν using the Branching Ratio of Z → £+£- measured at LEP and a theoretical value for the ratio of the cross sections. σZ Br(W → £ν) = R · W Br(Z → £+ £-) = 0.1054 ± 0.0016 We also obtain an indirect measurement of the W width of Γtot = 2148 ± 32 MeV. This width gives us information about all the possible decays of the W boson. The W width also constrains the sum of the CKM elements involved in W decays. We find the following value for V_cs , the least constrained element: |V_cs | = 1.008 ± 0.029.

Elements of the spin density matrix for W bosons in e+e- -> W+W- -> qqln events are measured from data recorded by the OPAL detector at LEP. This information is used calculate polarised differential cross-sections and to search for CP-violating effects. Results are presented for W bosons produced in e+e- collisions with centre-of-mass energies between 183 GeV and 209 GeV. The average fraction of W bosons that are longitudinally polarised is found to be (23.9 +- 2.1 +- 1.1)% compared to a Standard Model prediction of (23.9 +- 0.1)%. All results are consistent with CP conservation.

Full Text Available Conference of the family group (KGR is a method of the work with the family leading families in functioning to positive changes, giving the possibility of constructive and effective solving her problems. The specificity of this method causes employing the wide circle of members of a family, as well as other persons important for the child: of acquaintances, of neighbors, of friends; on the established forum discussion is being entered into with the possibility of using the participation of professionals, granting technical consultation; plans concerning solving difficult situations of the child and the family are being formulated. The KGR method is applied in final years in, bringing unprecedented beneficial results. Thanks to conducting fifteen conferences of the family group in the district of Bytów over twenty children missed to institutions social and behavioral, and it stayed in related and unrelated foster families and around their families. Moreover the families received the psychological support, possibility to use the services of the assistant of the family and the assistant of the person with disabilities. Drawing fifteen social contracts up was a final result of held conferences. All members of a family are becoming involved in the problem solving, behind taken decisions lives concerning them have a sense of responsibility, they are establishing positive reports with employees of the system of the welfare. Apart from that a number of children is reducing at institutions social and behavioral, a time of staying foster children in substitute forms of the care is undergoing shortening, also a number of institutional intervention is reducing in families

Selected Philosophers’ Views of the Family [Rodzina w poglądach wybranych filozofów

Directory of Open Access Journals (Sweden)

Full Text Available The subject matter of this article is the history of philosophical speculation on the family. Philosophical reflections on the family date back to Antiquity. The main points of reference for the entire socio-philosophical literature are the views of Plato and Aristotle. Plato’s recognition of private property and the family as the main barriers in the way of a perfect state has weighed on all concepts of equality for many centuries. On the other hand, Aristotle, recognizing the family as the basic social group, place of formation of virtues and one of the conditions of a happy life, contributed to consolidate the view of the distribution of social roles based on sex as natural and necessary. Medieval philosophers placed the family in the perspective of creation, this life, and salvation. Modern philosophical concepts of the family were completely different and sometimes contradictory. On the one hand, there were ideas of such thinkers as John J. Rousseau, with emphasis on the polarization of education and social roles by gender, on the other, strongly egalitarian views of Mary Wollstonecraft. Feminist considerations of Simone de Beauvoire conclude the review of philosophical views on the family

From a total data sample of 701.1 pb^-1 recorded with e+e- centre-of-mass energies of sqrt = 161-209 GeV with the OPAL detector at LEP, 11693 W-pair candidate events are selected. These data are used to obtain measurements of the W-pair production cross sections at 10 different centre-of-mass energies. The ratio of the measured cross sections to the Standard Model expectation is found to be: data/SM = 1.002 +- 0.011(stat.) +- 0.007(syst.) +- 0.005(theory), where the uncertainties are statistical, experimental systematics and theory systematics respectively. The data are used to determine the W boson branching fractions, which are found to be consistent with lepton universality of the charged current interaction. Assuming lepton universality, the branching ratio to hadrons is determined to be 67.41 +- 0.37(stat.) +- 0.23(syst.)%, from which the CKM matrix element Vcs is determined to be 0.96+-0.017(stat.)+-0.012(syst.). The differential cross section as a function of the W^- production angle is measured for th...

Vertical organizations of skeletal elements are found in various vertebrate teeth and invertebrate exoskeletons. The molecular mechanism behind the development of such structural organizations is poorly known, although it is generally held that organic matrix proteins play an essential role. While most crustacean cuticular organizations exhibit horizontal chitinous layering, a typical vertical organization is found towards the surface of the teeth in the mandibles of the crayfish Cherax quadricarinatus. Candidate genes encoding for mandible-forming structural proteins were mined in C. quadricarinatus molt-related transcriptomic libraries by using a binary patterning approach. A new protein family, termed the Mandible Alanine Rich Structural (MARS) protein family, with a modular sequence design predicted to form fibers, was found. Investigations of spatial and temporal expression of the different MARS genes suggested specific expression in the mandibular teeth-forming epithelium, particularly during the formation of the chitinous vertical organization. MARS loss-of-function RNAi experiments resulted in the collapse of the organization of the chitin fibers oriented vertically to the surface of the crayfish mandibular incisor tooth. A general search of transcriptomic libraries suggested conservation of MARS proteins across a wide array of crustaceans. Our results provide a first look into the molecular mechanism used to build the complex crustacean mandible and into the specialized vertical structural solution that has evolved in skeletal elements.

Structural insights into the regulation of Bacillus subtilis SigW activity by anti-sigma RsiW.

Directory of Open Access Journals (Sweden)

Shankar Raj Devkota

Full Text Available Bacillus subtilis SigW is localized to the cell membrane and is inactivated by the tight interaction with anti-sigma RsiW under normal growth conditions. Whereas SigW is discharged from RsiW binding and thus initiates the transcription of its regulon under diverse stress conditions such as antibiotics and alkaline shock. The release and activation of SigW in response to extracytoplasmic signals is induced by the regulated intramembrane proteolysis of RsiW. As a ZAS (Zinc-containing anti-sigma family protein, RsiW has a CHCC zinc binding motif, which implies that its anti-sigma activity may be regulated by the state of zinc coordination in addition to the proteolytic cleavage of RsiW. To understand the regulation mode of SigW activity by RsiW, we determined the crystal structures of SigW in complex with the cytoplasmic domain of RsiW, and compared the conformation of the CHCC motif in the reduced/zinc binding and the oxidized states. The structures revealed that RsiW inhibits the promoter binding of SigW by interacting with the surface groove of SigW. The interaction between SigW and RsiW is not disrupted by the oxidation of the CHCC motif in RsiW, suggesting that SigW activity might not be regulated by the zinc coordination states of the CHCC motif.

South African nursing environments are marked by various incapacitating stressors. This study explores work-family (W-F) and family-work (F-W) conflicts as aspects of stress amongst nurses working with patients who have AIDS. The study sought to determine the value of W-F and F-W conflicts as predictors of work and family satisfaction, as well as turnover intentions and the moderating role of supervisor and significant other support, amongst nurses caring for patients with AIDS in public hospitals within the Capricorn and Mopani districts, Limpopo Province. The study used a cross-sectional design, with data collected at one point only. Ninety-one nursing staff provided the data for the study by completing structured, self-administered surveys. Analysis involved computing correlations of all study variables. Thereafter, associated variables were used as predictors. In each predictive analysis, the nurses' stress served as a control variable, W-F and F-W conflicts were the independent variables and significant others and supervisor supports were moderators. Interaction terms were derived from independent and moderator variables. Although the findings of the study were not generally supportive of the hypotheses advanced, they nevertheless showed, amongst other findings, that F-W conflict predicted work satisfaction whilst W-F conflict predicted turnover intentions. Moreover, significant other support had a direct effect on family satisfaction whilst supervisor support moderated reports of W-F conflict and experiences of work satisfaction. The study showed that inter-role models that appear to be established in the context of developed societies require some further investigations in South Africa.

W-type barium ferrites Ba(MnZn) 0.3 Co 1.4 R 0.01 Fe 15.99 O 27 with R=Dy, Nd and Pr were prepared by chemical coprecipitation method. Effects of rare-earth elements (RE) substitution on microstructural and electromagnetic properties were analyzed. The results show that a small amount of RE 3+ ions can replace Fe 3+ ions and adjust hyperfine parameters. An obvious increase in natural resonance frequency and high frequency relaxation, and a sharp decrease for complex permittivity have been observed. Furthermore, the matching thickness and the reflection loss (RL) of one-layer ferrite absorber were calculated. It reveals that thin and broad-band can be obtained by RE-substitution. But only when the magnetic moment of RE 3+ is higher than that of Fe 3+ , can substitution be effective for higher RL. Dy-substituted ferrite composite has excellent microwave absorption properties. The frequency (with respect to -10 dB RL) begins from 9.9 GHz, and the bandwidth reaches far more than 8.16 GHz. The peak value is -51.92 dB at a matching thickness of 2.1 mm

The fabrication of the actively cooled high-heat flux divertor of the WENDELSTEIN 7-X stellarator (W7-X) requires the delivery of 890 target elements, which are designed to withstand a stationary heat flux of 10 MW/m 2 . The organization of the manufacturing and testing route for the serial fabrication is the result of the pre-series activities. Flat CFC Sepcarb NB31 tiles are bonded to CuCrZr copper alloy cooling structure in consecutive steps. A copper layer is active metal cast to CFC tiles, and then an OF-copper layer is added by hot isostatic pressing to produce bi-layer tiles. These tiles are bonded by electron beam welding onto the cooling structure, which was manufactured independently. The introduction of the bi-layer technology proved to be a significant improvement of the bond reliability under thermal cycling loading. This result is also the consequence of the improved bond inspections throughout the manufacturing route performed in the ARGUS pulsed thermography facility of PLANSEE. The repairing process by electron beam welding of the bonding was also qualified. The extended pre-series activities related to the qualification of fabrication processes with the relevant non-destructive examinations aim to minimize the risks for the serial manufacturing and to guarantee the steady-state operation of the W7-X divertor.

Human endogenous retrovirus K Gag coassembles with HIV-1 Gag and reduces the release efficiency and infectivity of HIV-1.

Human endogenous retroviruses (HERVs), which are remnants of ancestral retroviruses integrated into the human genome, are defective in viral replication. Because activation of HERV-K and coexpression of this virus with HIV-1 have been observed during HIV-1 infection, it is conceivable that HERV-K could affect HIV-1 replication, either by competition or by cooperation, in cells expressing both viruses. In this study, we found that the release efficiency of HIV-1 Gag was 3-fold reduced upon overexpression of HERV-K(CON) Gag. In addition, we observed that in cells expressing Gag proteins of both viruses, HERV-K(CON) Gag colocalized with HIV-1 Gag at the plasma membrane. Furthermore, HERV-K(CON) Gag was found to coassemble with HIV-1 Gag, as demonstrated by (i) processing of HERV-K(CON) Gag by HIV-1 protease in virions, (ii) coimmunoprecipitation of virion-associated HERV-K(CON) Gag with HIV-1 Gag, and (iii) rescue of a late-domain-defective HERV-K(CON) Gag by wild-type (WT) HIV-1 Gag. Myristylation-deficient HERV-K(CON) Gag localized to nuclei, suggesting cryptic nuclear trafficking of HERV-K Gag. Notably, unlike WT HERV-K(CON) Gag, HIV-1 Gag failed to rescue myristylation-deficient HERV-K(CON) Gag to the plasma membrane. Efficient colocalization and coassembly of HIV-1 Gag and HERV-K Gag also required nucleocapsid (NC). These results provide evidence that HIV-1 Gag heteromultimerizes with HERV-K Gag at the plasma membrane, presumably through NC-RNA interaction. Intriguingly, HERV-K Gag overexpression reduced not only HIV-1 release efficiency but also HIV-1 infectivity in a myristylation- and NC-dependent manner. Altogether, these results indicate that Gag proteins of endogenous retroviruses can coassemble with HIV-1 Gag and modulate the late phase of HIV-1 replication.

Semiconductor market demand for improved performance at lower cost continues to drive enhancements in excimer light source technologies. Increased output power, reduced variability in key light source parameters, and improved beam stability are required of the light source to support immersion lithography, multi-patterning, and 450mm wafer applications in high volume semiconductor manufacturing. To support future scanner needs, Cymer conducted a technology demonstration program to evaluate the design elements for a 120W ArFi light source. The program was based on the 90W XLR 600ix platform, and included rapid power switching between 90W and 120W modes to potentially support lot-to-lot changes in desired power. The 120W requirements also included improved beam stability in an exposure window conditionally reduced by 20%. The 120W output power is achieved by efficiency gains in system design, keeping system input power at the same level as the 90W XLR 600ix. To assess system to system variability, detailed system testing was conducted from 90W - 120W with reproducible results.

Hereditary sensory and autonomic neuropathy type I (HSAN I) is an autosomal dominant disorder of the peripheral nervous system characterized by marked progressive sensory loss, with variable autonomic and motor involvement. The HSAN I locus maps to chromosome 9q22.1-22.3 and is caused by mutations in the gene coding for serine palmitoyltransferase long chain base subunit 1 (SPTLC1). Sequencing in HSAN I families have previously identified mutations in exons 5, 6 and 13 of this gene. Here we report the clinical, electrophysiological and pathological findings of a proband in a Chinese family with HSAN I. The affected members showed almost typical clinical features. Electrophysiological findings showed an axonal, predominantly sensory, neuropathy with motor and autonomic involvement. Sural nerve biopsy showed loss of myelinated and unmyelinated fibers. SPTLC1 mutational analysis revealed the C133W mutation, a mutation common in British HSAN I families.

Proteins of the A-type lamin family, which consists of two members, lamin A and lamin C, are the major components of a thin proteinaceous filamentous meshwork, the lamina, that underlies the inner nuclear membrane. A-type lamins have recently become the focus of extensive functional studies as a consequence of the linking of at least eight congenital diseases to mutations in the lamin A/C gene (LMNA). This spectrum of pathologies, which mostly manifest themselves as dominant traits, includes muscle dystrophies, dilated cardiomyopathies, the premature aging syndrome Hutchinson-Guilford progeria and familial partial lipodystrophy (FPLD). The crystal structure of the lamin A/C mutant R482W, a variant that causes FPLD, has been determined at 1.5 {angstrom} resolution. A completely novel aggregation state of the C-terminal globular domain and the position of the mutated amino-acid residue suggest means by which the mutation may affect lamin A/C-protein and protein-DNA interactions.

Full Text Available Background: South African nursing environments are marked by various incapacitating stressors. This study explores work-family (W-F and family-work (F-W conflicts as aspects of stress amongst nurses working with patients who have AIDS. Objectives: The study sought to determine the value of W-F and F-W conflicts as predictors of work and family satisfaction, as well as turnover intentions and the moderating role of supervisor and significant other support, amongst nurses caring for patients with AIDS in public hospitals within the Capricorn and Mopani districts, Limpopo Province. Methods: The study used a cross-sectional design, with data collected at one point only. Ninety-one nursing staff provided the data for the study by completing structured, self-administered surveys. Analysis involved computing correlations of all study variables. Thereafter, associated variables were used as predictors. In each predictive analysis, the nurses’ stress served as a control variable, W-F and F-W conflicts were the independent variables and significant others and supervisor supports were moderators. Interaction terms were derived from independent and moderator variables. Results: Although the findings of the study were not generally supportive of the hypotheses advanced, they nevertheless showed, amongst other findings, that F-W conflict predicted work satisfaction whilst W-F conflict predicted turnover intentions. Moreover, significant other support had a direct effect on family satisfaction whilst supervisor support moderated reports of W-F conflict and experiences of work satisfaction. Conclusions: The study showed that inter-role models that appear to be established in the context of developed societies require some further investigations in South Africa.

Full Text Available Empress of Bulgarians, augusta and basilissa – Maria-Irene Lekapene and the transfer of the idea of imperial feminine in the Medieval Bulgaria Maria Lekapene was a granddaughter of Byzantine Emperor Romanos I Lekapenos. In 927 she married Peter I of Bulgaria. Her marriage, ceremoniously entered into in Constantinople, aimed to strengthen the newly signed Byzantine-Bulgarian peace treaty. Historians attributed to the Empress a significant impact on the political moves of her husband. The Empress was also to introduce a lot of elements of the Byzantine theory of power in Bulgaria.   Cesarzowa Bułgarów, augusta i bazylisa – Maria-Irena Lekapena i transfer bizantyńskiej idei kobiety-władczyni (imperial feminine w średniowiecznej Bułgarii Maria Lekapena była wnuczką cesarza bizantyńskiego Romana I Lekapena. W 927 roku poślubiła władcę Bułgarii, Piotra. Jej małżeństwo, uroczyście zawarte w Konstantynopolu, miało za zadanie umocnić dopiero co podpisany pokój bizantyńsko-bułgarski. Historycy przypisywali carycy znaczny wpływ na polityczne posunięcia jej męża. Władczyni miała też zaszczepić na gruncie bułgarskim wiele elementów bizantyńskiej teorii władzy.

Over last century, work was not only a means of economic survival, but also a very strong factor of psychological structuring and of organization of personal, family, and everyday life. The new world of work provides new challenges to the balance of work and family life. A questionnaire was administered to a sample of 453 people with the aim of analyzing the relation between variables such as family burdens and domestic responsibilities, and the appraisal of work and family, values involved in work-family balance. The results of this study show that, in the present economic and cultural context, assuming family burdens and domestic responsibilities increases the positive appraisal of work and family, both in men and women. This has theoretical and practical implications concerning the challenge of work-family balance.

The 'Severe Fuel Damage' (SFD) experiments of the Kernforschungszentrum Karlsruhe (KfK), Federal Republic of Germany, were carried out in the out-of-pile facility 'CORA' as part of the international Severe Fuel Damage (SFD) research. The experimental program was set up to provide information on the failure mechanisms of Light Water Reactor (LWR) fuel elements in a temperature range from 1200 C to 2000 C and in few cases up to 2400 C. Between 1987 and 1992 a total of 17 CORA experiments with two different bundle configurations, i.e. PWR (Pressurized Water Reactor) and BWR (Boiling Water Reactor) bundles were performed. These assemblies represented 'Western-type' fuel elements with the pertinent materials for fuel, cladding, grid spacer, and absorber rod. At the end of the experimental program two VVER-1000 specific tests were run in the CORA facility with identical objectives but with genuine VVER-type materials. The experiments, designated CORA-W1 and CORA-W2 were conducted on February 18, 1993 and April 21, 1993, respectively. Test bundle CORA-W1 was without absorber material whereas CORA-W2 contained one absorber rod (boron carbide/steel). As in the earlier CORA tests the test bundles were subjected to temperature transients of a slow heatup rate in a steam environment. The transient phases of the tests were initiated with a temperature ramp rate of 1 K/s. With these conditions a so-called small-break LOCA was simulated. The temperature escalation due to the exothermal zircon/niobium-steam reaction started at about 1200 C, leading the bundles to maximum temperatures of approximately 1900 C. The thermal response of bundle CORA-W2 is comparable to that of CORA-W1. In test CORA-W2, however, the temperature front moved faster from the top to the bottom compared to test CORA-W1 [de

  Streszczenie   Wprowadzenie: Wiek przedszkolny to najlepszy okres rozwojowy do kształtowania nawyków, postaw i umiejętności życiowych. Rodzina i przedszkole to środowiska, w których występuje edukacja zdrowotna dziecka. Od rodziny oczekuje się stworzenia warunków zapewniających bezpieczeństwo i zaspokojenie zdrowotnych potrzeb dziecka, a także organizacji życia zgodnego z zasadami higieny somatycznej i psychicznej. Dziecko przebywa w przedszkolu wiele godzin, zdobywa podstawowe informacje i umiejętności dbania o zdrowie i bezpieczeństwo. Cel pracy: Ocena wpływu edukacji zdrowotnej na zachowania zdrowotne dzieci w wieku przedszkolnym z perspektywy rodziców. Materiał i metody: Badanie zostało przeprowadzone metodą sondażu diagnostycznego. Wykorzystanym narzędziem był autorski kwestionariusz. Grupę badaną stanowiło 105 rodziców w 1. etapie badania oraz 127 rodziców w 2. etapie badania. Wyniki: Większość ankietowanych (76% jest zdania, że wczesna edukacja zdrowotna ma bardzo duże znaczenie dla rozwoju i stanu zdrowia dzieci. Około 77% badanych rodziców jest zdania, że dzieci wykorzystują wiedzę zdobytą w przedszkolu w życiu codziennym. Połowa badanych (52% jest zdania, że zachowania zdrowotne dzieci znacznie się poprawiły po zajęciach z edukacji zdrowotnej. Wnioski: Rodzice doceniają rolę wczesnej edukacji zdrowotnej w rozwoju i zdrowiu dzieci. Edukacja zdrowotna w przedszkolu przyczynia się do wzrostu zainteresowania zdrowiem wśród dzieci. Środowisko rodzinne może mieć pozytywny wpływ na zachowania prozdrowotne dzieci. Część rodzin nie zapewnia dzieciom właściwych warunków do wychowania zdrowotnego, dlatego należy rozważyć implementację działań edukacyjnych skierowanych do osób planujących bądź posiadających dzieci. Należy dążyć do zwiększenia roli osób wykonujących zawody medyczne w promocji zdrowia.   Abstract   Introduction: Preschool is the best period to acquire habits

Short interspersed nuclear elements (SINEs) are non-long terminal repeat retrotransposons that are highly abundant, heterogeneous, and mostly not annotated in eukaryotic genomes. We developed a tool designated SINE-Finder for the targeted discovery of tRNA-derived SINEs. We analyzed sequence data of 16 plant genomes, including 13 angiosperms and three gymnosperms and identified 17,829 full-length and truncated SINEs falling into 31 families showing the widespread occurrence of SINEs in higher plants. The investigation focused on potato (Solanum tuberosum), resulting in the detection of seven different SolS SINE families consisting of 1489 full-length and 870 5' truncated copies. Consensus sequences of full-length members range in size from 106 to 244 bp depending on the SINE family. SolS SINEs populated related species and evolved separately, which led to some distinct subfamilies. Solanaceae SINEs are dispersed along chromosomes and distributed without clustering but with preferred integration into short A-rich motifs. They emerged more than 23 million years ago and were species specifically amplified during the radiation of potato, tomato (Solanum lycopersicum), and tobacco (Nicotiana tabacum). We show that tobacco TS retrotransposons are composite SINEs consisting of the 3' end of a long interspersed nuclear element integrated downstream of a nonhomologous SINE family followed by successfully colonization of the genome. We propose an evolutionary scenario for the formation of TS as a spontaneous event, which could be typical for the emergence of SINE families.

Akt is a serine threonine kinase with a major role in transducing survival signals and regulating proteins involved in apoptosis. To find new interactors of Akt involved in cell survival, we performed a two-hybrid screening in yeast using human full-length Akt c-DNA as bait and a murine c-DNA library as prey. Among the 80 clones obtained, two were identified as Bcl-w. Bcl-w is a member of the Bcl-2 family that is essential for the regulation of cellular survival, and that is up-regulated in different human tumors, such as gastric and colorectal carcinomas. Direct interaction of Bcl-w with Akt was confirmed by immunoprecipitation assays. Subsequently, we addressed the function of this interaction: by interfering with the activity or amount of Akt, we have demonstrated that Akt modulates the amount of Bcl-w protein. We have found that inhibition of Akt activity may promote apoptosis through the downregulation of Bcl-w protein and the consequential reduction in interaction of Bcl-w with pro-apoptotic members of the Bcl-2 family. Our data provide evidence that Bcl-w is a new member of the Akt pathway and that Akt may induce anti-apoptotic signals at least in part through the regulation of the amount and activity of Bcl-w.

Genome-wide comparative analysis of 20 miniature inverted-repeat transposable element families in Brassica rapa and B. oleracea.

Full Text Available Miniature inverted-repeat transposable elements (MITEs are ubiquitous, non-autonomous class II transposable elements. Here, we conducted genome-wide comparative analysis of 20 MITE families in B. rapa, B. oleracea, and Arabidopsis thaliana. A total of 5894 and 6026 MITE members belonging to the 20 families were found in the whole genome pseudo-chromosome sequences of B. rapa and B. oleracea, respectively. Meanwhile, only four of the 20 families, comprising 573 members, were identified in the Arabidopsis genome, indicating that most of the families were activated in the Brassica genus after divergence from Arabidopsis. Copy numbers varied from 4 to 1459 for each MITE family, and there was up to 6-fold variation between B. rapa and B. oleracea. In particular, analysis of intact members showed that whereas eleven families were present in similar copy numbers in B. rapa and B. oleracea, nine families showed copy number variation ranging from 2- to 16-fold. Four of those families (BraSto-3, BraTo-3, 4, 5 were more abundant in B. rapa, and the other five (BraSto-1, BraSto-4, BraTo-1, 7 and BraHAT-1 were more abundant in B. oleracea. Overall, 54% and 51% of the MITEs resided in or within 2 kb of a gene in the B. rapa and B. oleracea genomes, respectively. Notably, 92 MITEs were found within the CDS of annotated genes, suggesting that MITEs might play roles in diversification of genes in the recently triplicated Brassica genome. MITE insertion polymorphism (MIP analysis of 289 MITE members showed that 52% and 23% were polymorphic at the inter- and intra-species levels, respectively, indicating that there has been recent MITE activity in the Brassica genome. These recently activated MITE families with abundant MIP will provide useful resources for molecular breeding and identification of novel functional genes arising from MITE insertion.

Park, K. C.; Alexander, Scott

1992-01-01

A family of preconditioners for the solution of finite element equations are presented, which are element-topology independent and thus can be applicable to element order-free parallel computations. A key feature of the present preconditioners is the repeated use of element connectivity matrices and their left and right inverses. The properties and performance of the present preconditioners are demonstrated via beam and two-dimensional finite element matrices for implicit time integration computations.

The WRKY family, one of the largest families of transcription factors, plays important roles in the regulation of various biological processes, including growth, development and stress responses in plants. In the present study, 63 DoWRKY genes were identified from the Dendrobium officinale genome. These were classified into groups I, II, III and a non-group, each with 14, 28, 10 and 11 members, respectively. ABA-responsive, sulfur-responsive and low temperature-responsive elements were identified in the 1-k upstream regulatory region of DoWRKY genes. Subsequently, the expression of the 63 DoWRKY genes under cold stress was assessed, and the expression profiles of a large number of these genes were regulated by low temperature in roots and stems. To further understand the regulatory mechanism of DoWRKY genes in biological processes, potential WRKY target genes were investigated. Among them, most stress-related genes contained multiple W-box elements in their promoters. In addition, the genes involved in polysaccharide synthesis and hydrolysis contained W-box elements in their 1-k upstream regulatory regions, suggesting that DoWRKY genes may play a role in polysaccharide metabolism. These results provide a basis for investigating the function of WRKY genes and help to understand the downstream regulation network in plants within the Orchidaceae.

A Family of Multipoint Flux Mixed Finite Element Methods for Elliptic Problems on General Grids

KAUST Repository

Wheeler, Mary F.

2011-01-01

In this paper, we discuss a family of multipoint flux mixed finite element (MFMFE) methods on simplicial, quadrilateral, hexahedral, and triangular-prismatic grids. The MFMFE methods are locally conservative with continuous normal fluxes, since they are developed within a variational framework as mixed finite element methods with special approximating spaces and quadrature rules. The latter allows for local flux elimination giving a cell-centered system for the scalar variable. We study two versions of the method: with a symmetric quadrature rule on smooth grids and a non-symmetric quadrature rule on rough grids. Theoretical and numerical results demonstrate first order convergence for problems with full-tensor coefficients. Second order superconvergence is observed on smooth grids. © 2011 Published by Elsevier Ltd.

Immunomodulacyjne właściwości makrolidów – zastosowanie w leczeniu chorób układu oddechowego u dzieci

2012-11-01

Full Text Available Odmienności budowy i czynności układu oddechowego u dzieci predysponują do częstszego występowania zakażeń. Podstawą działania antybiotyków makrolidowych są ich właściwości bakteriostatyczne wynikające z blokowania podjednostki 50s i 23s rRNA. Makrolidy wykazują szereg dodatkowych działań pozarybosomalnych. Działanie to obejmuje wpływ na komórki układu odpornościowego, odpowiedź cytoki‑ nową, układ oddechowy i metabolizm glikokortykosteroidów. W pracy przedstawiono aktualną wiedzę doty‑ czącą mechanizmów działania tej grupy antybiotyków. Makrolidy zmniejszają ilość neutrofilów w miejscu zapalenia poprzez hamowanie wydzielania czynników chemotaktycznych, blokowanie cząsteczek powierzch‑ niowych biorących udział w procesie migracji oraz kierowanie komórek zapalnych na drogę apoptozy. Wielo‑ kierunkowy wpływ antybiotyków makrolidowych na odpowiedź cytokinową sprowadza się głównie do obni‑ żania wydzielania cytokin prozapalnych i hamowania syntezy tlenku azotu. Ponadto zapobiegają one kolonizacji dróg oddechowych przez P. aeruginosa, co wynika z faktu blokowania przez makrolidy produkcji składników biofilmu, elementów układu quorum sensing (umożliwiającego komunikację się bakterii i hamo‑ wania produkcji czynników zjadliwości. Stosowanie makrolidów zmniejsza również produkcję śluzu w ukła‑ dzie oddechowym i poprawia klirens rzęskowy. Cytowane w opracowaniu badania dowodzą skuteczności makrolidów w zmniejszaniu nadprodukcji śluzu w drogach oddechowych i zapobieganiu kolonizacji przez P. aeruginosa u pacjentów z mukowiscydozą. Ponadto zmniejszają one częstość zaostrzeń i poprawiają jakość życia tych chorych. Nie zaobserwowano jednak istotnej poprawy parametrów spirometrycznych.

Hard photons in W pair production at LEP 2

International Nuclear Information System (INIS)

Oldenborgh, G.J. van

1996-01-01

The properties of hard photon radiation in W pair production at LEP 2 are studied, with emphasis on the energy loss relevant to the W mass measurement. We use a combination of the exact one-photon matrix element and leading logarithmic structure functions. Defining unobservable, observable and initial-state photons in the phase space, it is shown that neither the one-photon matrix element nor the leading logarithmic structure functions alone give an adequate description of the energy loss due to observable or initial-state photons. An event generator based on these calculations is available. (orig.)

A measurement of W^+W^- production in pp collisions at sqrt(s) = 7 TeV and a search for the Higgs boson are reported. The W^+W^- candidates are selected in events with two leptons, either electrons or muons. The measurement is performed using LHC data recorded with the CMS detector, corresponding to an integrated luminosity of 36 inverse picobarns. The pp to W^+W^- cross section is measured to be 41.1 ± 15.3 (stat) ± 5.8 (syst) ± 4.5 (lumi) pb, consistent with the standard model prediction. Limits on WW gamma and WWZ anomalous triple gauge couplings are set. The search for the standard model Higgs boson in the W^+W^- decay mode does not reveal any evidence of excess above backgrounds. Limits are set on the production of the Higgs boson in the context of the standard model and in the presence of a sequential fourth family of fermions with high masses. In the latter context, a Higgs boson with mass between 144 and 207 GeV/c2 is ruled out at 95% confidence level.

Even though 112 chemical elements are presently known, for elements with atomic numbers above 105 only nuclear decay properties have been investigated so far. Such data allow to proof the existence of a given nuclide, but they do not yield any information with respect to the position of a chemical element in the Periodic Table. We have performed ever first chemical investigations of element 106. According to the Periodic Table element 106 should be a member of group 6, having similar chemical properties as W, Mo and Cr. Two different techniques were applied to separate and identify element 106: a liquid chromatography system (ARCA = Automated Rapid Chemistry Apparatus) and a continuous isothermal chromatography device (OLGA = On-Line Gaschemistry Apparatus). With ARCA about 5'000 separations on small cation exchange columns (Aminex A6) with a 0.1 M HNO 3 /5.10 -4 M Hf solution were performed and with OLGA the gas adsorption behaviour of oxychlorides on quartz columns using Cl 2 /SOCl 2 /O 2 as reactive gas were studied. On the basis of only ten detected atoms, it was possible to proof that element 106 forms complexes which are eluted at positions similar to those of Mo and W. In addition, in the gas phase element 106 forms oxychlorides of lower volatility compared to those of Mo and W. (author) 1 ref

Human murine mammary tumour virus-like agents are genetically distinct from endogenous retroviruses and are not detectable in breast cancer cell lines or biopsies

It has been reported that a human murine mammary tumour virus (MMTV)-like virus (HMLV), which may be an endogenous human retrovirus (HERV), occurs in the human breast cancer cell lines T47D and MCF-7 and, in 38% of human breast cancer biopsies. As the aetiology of most breast cancers remains unknown, it is important to verify these observations in differing breast cancer populations worldwide. Thus, we sought to determine the genetic relationships between HMLVs, MMTVs, and HERVs, and to investigate the association between HMLVs and breast cancer biopsies from South London, UK. Phylogenetic analyses of the env/pol region indicated that HMLVs are indistinct from MMTVs, and that MMTVS/HMLVs exhibit only low sequence homologies with HERVs. A search of the human genome confirmed that HMLVs are not endogenous. Using MMTV polymerase chain reaction (PCR) primers described previously, we amplified DNA from all cell lines except MCF-7 and from 7 of 44 (16%) breast cancer biopsies. A restriction fragment length polymorphism assay was designed to distinguish between HMLVs and MMTVs, and upon analyses, PCR amplicons appeared to be HMLVs. To confirm these findings, amplicons from the T47D cell line and from four randomly selected breast cancer patients were sequenced. Of 106 DNA sequences obtained, 103 were homologous with a short arm of human chromosome (Chr) 3 (3p13), two with Chr 4, and one with Chr 8. None of the sequences exhibited significant nucleotide homology with MMTVs, HMLVs, or with HERVs (all <50%). Thus, we conclude that (i) HMLVs are integral members of the MMTV family; (ii) MMTVs/HMLVs are genetically distinct from HERVs; (iii) MMTV/HMLV DNA is not present in human breast cancer cell lines or clinical biopsies in our locality

Full Text Available Miasta ulegają ciągłym przeobrażeniom. Nowy kształt urbanistyczny i nowa zabudowa wkraczają do dzielnic historycznych miast. Zachowana zabytkowa architektura przeważnie nie zawiera spektakularnych obiektów. Natomiast jako całość jest cennym świadkiem epoki. W miasteczkach nierzadko ważną rolę odgrywa zabudowa drewniana, chociaż przeważnie zachowana w szczątkowym stanie. Na Podlasiu duże nasycenie zabudową drewnianą było charakterystyczne dla małych miast. Jednym z nich jest Bielsk Podlaski. Na jego przykładzie zostanie omówiony problem zmiany dawnego charakteru miasta, którego ważnym elementem była architektura drewniana.

Rola leptyny w regulacji metabolizmu lipidów i węglowodanów

Full Text Available Leptyna jest białkiem wydzielanym głównie przez tkankę tłuszczową, a jej stężenie we krwi jest ściśle związane z ilością zapasów energetycznych zgromadzonych w adipocytach. Jako hormon leptyna ma niezwykle szeroki zakres działania. Białko to bezpośrednio lub za pośrednictwem układu współczulnego bierze udział w regulacji metabolizmu energetycznego. Leptyna hamuje biosyntezę triacylogliceroli w wątrobie i tkance tłuszczowej, a także w mięśniach szkieletowych, obniżając tym samym ilość odkładanych w nich lipidów. W adipocytach leptyna zmniejsza ekspresję genów kodujących syntazę kwasów tłuszczowych (FAS i karboksylazę acetylo-CoA (ACC – główne enzymy szlaku biosyntezy kwasów tłuszczowych. Zwiększa z kolei ekspresję genu kodującego lipazę zależną od hormonów (HSL, co stymuluje hydrolizę triacylogliceroli w tkance tłuszczowej. Ponadto leptyna wzmaga utlenianie kwasów tłuszczowych w adipocytach, mięśniach szkieletowych oraz w mięśniu sercowym, wywołując wzrost ekspresji genów kodujących podstawowe dla tego procesu enzymy, palmitoilotransferazę karnitynową 1 (CPT1 i dehydrogenazę acylo-CoA o średniej długości łańcucha (MCAD. Wykazano również, że hormon ten zwiększa wrażliwość tkanek na insulinę i poprawia tolerancję glukozy – pod wpływem leptyny wzrasta transport glukozy do komórek oraz intensywność glikolizy.Wiadomo, że leptyna bierze udział w długoterminowej regulacji pobierania pokarmu, jednak coraz więcej badań wskazuje, że ma ona również wpływ na przemiany substratów energetycznych w tkankach obwodowych. Leptyna może zatem kontrolować homeostaz�� energetyczną organizmu wywołując zmiany metabolizmu lipidów i węglowodanów, przede wszystkim w tkance tłuszczowej i w mięśniach.

Heterologous regulatory elements and flanking sequences have been used in chloroplast transformation of several crop species, but their roles and mechanisms have not yet been investigated. Nucleotide sequence identity in the photosystem II protein D1 (psbA) upstream region is 59% across all taxa; similar variation was consistent across all genes and taxa examined. Secondary structure and predicted Gibbs free energy values of the psbA 5′ untranslated region (UTR) among different families reflected this variation. Therefore, chloroplast transformation vectors were made for tobacco (Nicotiana tabacum) and lettuce (Lactuca sativa), with endogenous (Nt-Nt, Ls-Ls) or heterologous (Nt-Ls, Ls-Nt) psbA promoter, 5′ UTR and 3′ UTR, regulating expression of the anthrax protective antigen (PA) or human proinsulin (Pins) fused with the cholera toxin B-subunit (CTB). Unique lettuce flanking sequences were completely eliminated during homologous recombination in the transplastomic tobacco genomes but not unique tobacco sequences. Nt-Ls or Ls-Nt transplastomic lines showed reduction of 80% PA and 97% CTB-Pins expression when compared with endogenous psbA regulatory elements, which accumulated up to 29.6% total soluble protein PA and 72.0% total leaf protein CTB-Pins, 2-fold higher than Rubisco. Transgene transcripts were reduced by 84% in Ls-Nt-CTB-Pins and by 72% in Nt-Ls-PA lines. Transcripts containing endogenous 5′ UTR were stabilized in nonpolysomal fractions. Stromal RNA-binding proteins were preferentially associated with endogenous psbA 5′ UTR. A rapid and reproducible regeneration system was developed for lettuce commercial cultivars by optimizing plant growth regulators. These findings underscore the need for sequencing complete crop chloroplast genomes, utilization of endogenous regulatory elements and flanking sequences, as well as optimization of plant growth regulators for efficient chloroplast transformation.

As heat exhaust capability and lifetime of plasma-facing component (PFC) during in-situ operation are linked to the manufacturing quality, a set of non-destructive testing must be operated during R-and-D and manufacturing phases. Within this framework, advanced non-destructive examination (NDE) methods are one of the key issues to achieve a high level of quality and reliability of joining techniques in the production of high heat flux components but also to develop and built successfully PFCs for a next generation of fusion devices. In this frame, two NDE infrared thermographic approaches, which have been recently applied to the qualification of CFC target elements of the W7-X divertor during the first series production will be discussed in this paper. The first one, developed by CEA (SATIR facility) and used with successfully to the control of the mass-produced actively cooled PFCs on Tore Supra, is based on the transient thermography where the testing protocol consists in inducing a thermal transient within the heat sink structure by an alternative hot/cold water flow. The second one, recently developed by PLANSEE (ARGUS facility), is based on the pulsed thermography where the component is heated externally by a single powerful flash of light. Results obtained on qualification experiences performed during the first series production of W7-X divertor components representing about thirty mock-ups with artificial and manufacturing defects, demonstrated the capabilities of these two methods and raised the efficiency of inspection to a level which is appropriate for industrial application. This comparative study, associated to a cross-checking analysis between the high heat flux performance tests and these inspection methods by infrared thermography, showed a good reproducibility and allowed to set a detectable limit specific at each method. Finally, the detectability of relevant defects showed excellent coincidence with thermal images obtained from high heat flux

Neuropeptide W

Full Text Available Neuropeptide W (NPW, which was first isolated from the porcine hypothalamus, exists in two forms, consisting of 23 (NPW23 or 30 (NPW30 amino acids. These neuropeptides bind to one of two neuropeptide W receptors, either NPBWR1 (otherwise known as GPR7 or NPBWR2 (GPR8, which belong to the G protein-coupled receptor family. GPR7 is expressed in the brain and peripheral organs of both humans and rodents, whereas GPR8 is not found in rodents. GPR7 mRNA in rodents is widely expressed in several hypothalamic regions, including the paraventricular, supraoptic, ventromedial, dorsomedial, suprachiasmatic and arcuate nuclei. These observations suggest that GPR7 plays a crucial role in the modulation of neuroendocrine function. The intracerebroventricular infusion of NPW has been shown to suppress food intake and body weight and to increase both heat production and body temperature, suggesting that this neuropeptide functions as an endogenous catabolic signaling molecule. Here we summarize our current understanding of the distribution and function of NPW in the brain.

Full Text Available The situation of Polish families during Stalinist subjugation was particularly arduous. The family was treated as an important part of the political system’s socialization which was not rooted at all in the sphere of traditional values and norms developed in the process of historical progress of the Polish statehood. Due to the foundations of Latin civilization based on personalization that were cherished by Polish families, cynical endeavors to take away freedom, legal capacity and personal property – the objectives which Stalinism aimed at both indirectly and directly – failed, which destroyed the communists’ plans. The family did not cease to be the most important centre of human life and development. Theoreticians of a „new deal” did not manage to limit the family to the role of a „basic social unit” of „socialist morality”.

Family ties and intergenerational relationships in European families in the twentieth century [Więzy rodzinne i relacje międzypokoleniowe w rodzinach europejskich w XX wieku

Full Text Available Intergenerational family relationships still performed an important social function in rural society in Europe at the beginning of the twentieth century. The situation within the Czech family illustrates the current problems in family ties and intergenerational relationships that have surfaced since the nineteen nineties. Negative developmental trends are being seen, particularly in comparison with family circumstances in other European countries, most significantly the continuing ageing of the population and the wide-ranging activities of seniors. Looser relationships with their families and a decline in their engagement in caring for their grandchildren mean that Czech grandparents tend to rank alongside more socially developed countries in this respect. Under Czech conditions, however, this can lead to great strain on the active roles played by seniors. The growing number of adult offspring, particularly men, living with their parents is a far from progressive trend in social and economic development, and corresponds more closely with southern European traditions. A preference for alternative forms of cohabitation, particularly among partners with primary education, the postponing of the birth of the first child, the growth in the number of single-person households and, perhaps most importantly, the enormous rise in the number of households comprised of young or middle-aged individuals in the economically productive age group may, it is true, rank the Czech Republic among socially developed countries and at around the European average, though in view of the unfavourable demographic trend a fundamental change in state support for marriage and the family is, however, also essential in the Czech Republic. The fact is that more than a third of families with children are threatened with poverty. The conclusion arising from the analyses performed indicates that the current problems in state social and family policy are reflected in the increasing

This article assessed work-to-family conflict (W-FC) and family-to-work conflict (F-WC) and their impact on depression among corrections officers in two correctional facilities in the United States. The sample consisted of 220 officers who completed questionnaires that included data on demographics, sense of coherence (SOC), physical health, psychosocial job characteristics, and work-family conflict. The Center for Epidemiologic Studies Depression Scale (CES-D-10) assessed depression. The mean CES-D score was 7.8 (SD = 5.2); 31% had scores of 10 or more, indicative of serious psychological distress. The SOC, W-FC, and F-WC were significantly and positively associated with depression; W-FC mediated the effects of SOC on depression. Psychosocial job characteristics were not related to depression. Depressive symptoms were high among officers, and W-FC was a critical factor contributing to psychological distress.

The magnet support system of the Wendelstein 7-X (W7-X) fusion stellarator includes challenging components, called Narrow Support Elements (NSEs), placed between the Non Planar Coils (NPCs) at the inboard side and aimed at reducing deformation of the coils. NSEs are small contact elements, with special coating to reduce friction, that have to withstand high compressive and shear forces. The objective of this article is to demonstrate the structural reliability of the NSEs under electromagnetic loading (EML), taking into account in a conservative way the relevant material properties at cryogenic temperatures. To this purpose, an appropriate parametric local Finite Element (FE) model of one highly loaded NSE with its components (pad, pad frame and counter pad) and of a portion of the coils has been developed with ABAQUS code and isotropic elastic-plastic material model with hardening/softening has been used, in order to include the serration effect at 4 K. Different mechanical limit analyses have been performed including consecutive steps of shrink fitting the NSEs in the coils, cooling down to 4 K and gradual increasing of the coil displacements induced by the EML.

The relationship between infections and autoimmune diseases is complex and there are several reports highlighting the role of human endogenous retroviruses (HERVs) in these patients. The levels of multiple sclerosis-associated retrovirus (MSRV)-type DNA of Env gene was measured in peripheral blood mononuclear cells from 52 patients with relapsing-remitting multiple sclerosis (RRMS) and 40 healthy controls using specific quantitative PCR (qPCR) analysis. Furthermore, we analyzed the status of HERV-W/MSRV in these patients with regards to both EBV (DNA load and anti-EBNA1 IgG antibody) and vitamin D concentration. MSRV DNA copy number were significantly higher in RRMS patients than healthy controls (P < 0.0001). Interestingly, an inverse correlation was found between MSRV DNA copy number and serum vitamin D concentration (P < 0.01), but not for EBV load or anti-EBNA-1 IgG antibody. © 2017 Wiley Periodicals, Inc.

Chemical Abundance Analysis of Moving Group W11450 (Latham 1)

O'Connell, Julia E.; Martens, Kylee; Frinchaboy, Peter M.

2016-12-01

We present elemental abundances for all seven stars in Moving Group W11450 (Latham 1) to determine if they may be chemically related. These stars appear to be both spatially and kinematically related, but no spectroscopic abundance analysis exists in literature. Abundances for eight elements were derived via equivalent width analyses of high-resolution (R ˜ 60,000), high-signal-to-noise ratio ( ˜ 100) spectra obtained with the Otto Struve 2.1 m telescope and the Sandiford Echelle Spectrograph at McDonald Observatory. The large star-to-star scatter in metallicity, -0.55 ≤ [Fe/H] ≤slant 0.06 dex (σ = 0.25), implies these stars were not produced from the same chemically homogeneous molecular cloud, and are therefore not part of a remnant or open cluster as previously proposed. Prior to this analysis, it was suggested that two stars in the group, W11449 and W11450, are possible wide binaries. The candidate wide binary pair show similar chemical abundance patterns with not only iron but with other elements analyzed in this study, suggesting the proposed connection between these two stars may be real.

Full Text Available Wielonienasycone kwasy tłuszczowe (WKT omega-3 są niezbędne do prawidłowego rozwoju i funkcji ośrodkowego układu nerwowego. Stanowią istotny element strukturalny neuronalnych błon komórkowych oraz są źródłem aktywnych biologicznie substancji, które pełnią złożone funkcje sygnałowe oraz uczestniczą w przekazywaniu informacji wewnątrz komórek. Zaburzenia metabolizmu lipidów i WKT obserwuje się w przebiegu wielu zaburzeń i chorób psychicznych: schizofrenii, zaburzeń afektywnych, zespołu nadpobudliwości psychoruchowej z deficytem uwagi, autyzmu i innych. Dysfunkcje te mają podłoże genetyczne i wraz z innymi nieprawidłowościami przyczyniają się do zwiększenia podatności na wystąpienie objawów psychopatologicznych danego zaburzenia. Ponadto dieta mieszkańców większości krajów europejskich nie zapewnia wystarczającej ilości WKT omega-3, które należą do substancji egzogennych, tj. niesyntetyzowanych w wystarczającej ilości w organizmie ludzkim. Co więcej, w przebiegu wielu zaburzeń psychicznych dochodzi do nadmiernej utraty długołańcuchowych WKT za pośrednictwem procesów ekscytotoksyczności i stresu oksydacyjnego, co dalej przyczynia się do uszczuplenia dostępnej puli WKT. W przypadku schizofrenii liczne badania eksperymentalne i kliniczne doprowadziły badaczy do sformułowania hipotezy wyjaśniającej rozwój tej choroby w oparciu o występowanie dysfunkcji metabolizmu lipidów. W pracy przedstawiono przegląd aktualnego piśmiennictwa oraz wyniki oryginalnych badań przeprowadzonych przez autorów zajmujących się problematyką zaburzeń metabolizmu WKT u chorych z wymienionymi wyżej zaburzeniami psychicznymi.

Characterization of novel W alloys produced by HIP

W and W alloys containing 0.5 wt% Y 2 O 3 , x wt% Ti and (x wt% Ti + 0.5 wt% Y 2 O 3 ) have been prepared, x = 2 or 4. Elemental powders were blended or ball milled, canned, degassed and finally consolidated by a two-stage HIP process under a pressure of 195 MPa. It is found that Ti addition favours the densification attaining a fully dense material. XRD, SEM and EDX analyses of the material with Ti addition reveal the formation of a microstructure consisting of tungsten particles embedded in a W-Ti matrix. The microhardness of these materials increased noticeably with the titanium content.

Using data recorded at centre-of-mass energies around 183 GeV and 189 GeV with the OPAL detector at LEP, the fundamental coupling of the charm quark to the W boson has been studied. The ratio Rc^W = Gamma(W -> cX)/Gamma(W -> hadrons) has been measured from jet properties, lifetime information, and leptons produced in charm decays. A value compatible with the Standard Model expectation of 0.5 is obtained: Rc^W = 0.481 +- 0.042(stat.) +- 0.032(syst.). By combining this result with measurements of the W boson total width and hadronic branching ratio, the magnitude of the CKM matrix element Vcs is determined to be |Vcs| = 0.969 +- 0.058.

Characterizing the original ejection velocity field of the Koronis family

Science.gov (United States)

Carruba, V.; Nesvorný, D.; Aljbaae, S.

2016-06-01

An asteroid family forms as a result of a collision between an impactor and a parent body. The fragments with ejection speeds higher than the escape velocity from the parent body can escape its gravitational pull. The cloud of escaping debris can be identified by the proximity of orbits in proper element, or frequency, domains. Obtaining estimates of the original ejection speed can provide valuable constraints on the physical processes occurring during collision, and used to calibrate impact simulations. Unfortunately, proper elements of asteroids families are modified by gravitational and non-gravitational effects, such as resonant dynamics, encounters with massive bodies, and the Yarkovsky effect, such that information on the original ejection speeds is often lost, especially for older, more evolved families. It has been recently suggested that the distribution in proper inclination of the Koronis family may have not been significantly perturbed by local dynamics, and that information on the component of the ejection velocity that is perpendicular to the orbital plane (vW), may still be available, at least in part. In this work we estimate the magnitude of the original ejection velocity speeds of Koronis members using the observed distribution in proper eccentricity and inclination, and accounting for the spread caused by dynamical effects. Our results show that (i) the spread in the original ejection speeds is, to within a 15% error, inversely proportional to the fragment size, and (ii) the minimum ejection velocity is of the order of 50 m/s, with larger values possible depending on the orbital configuration at the break-up.

Infectious Entry Pathway Mediated by the Human Endogenous Retrovirus K Envelope Protein.

Science.gov (United States)

Robinson, Lindsey R; Whelan, Sean P J

2016-01-20

Endogenous retroviruses (ERVs), the majority of which exist as degraded remnants of ancient viruses, comprise approximately 8% of the human genome. The youngest human ERVs (HERVs) belong to the HERV-K(HML-2) subgroup and were endogenized within the past 1 million years. The viral envelope protein (ENV) facilitates the earliest events of endogenization (cellular attachment and entry), and here, we characterize the requirements for HERV-K ENV to mediate infectious cell entry. Cell-cell fusion assays indicate that a minimum of two events are required for fusion, proteolytic processing by furin-like proteases and exposure to acidic pH. We generated an infectious autonomously replicating recombinant vesicular stomatitis virus (VSV) in which the glycoprotein was replaced by HERV-K ENV. HERV-K ENV imparts an endocytic entry pathway that requires dynamin-mediated membrane scission and endosomal acidification but is distinct from clathrin-dependent or macropinocytic uptake pathways. The lack of impediments to the replication of the VSV core in eukaryotic cells allowed us to broadly survey the HERV-K ENV-dictated tropism. Unlike extant betaretroviral envelopes, which impart a narrow species tropism, we found that HERV-K ENV mediates broad tropism encompassing cells from multiple mammalian and nonmammalian species. We conclude that HERV-K ENV dictates an evolutionarily conserved entry pathway and that the restriction of HERV-K to primate genomes reflects downstream stages of the viral replication cycle. Approximately 8% of the human genome is of retroviral origin. While many of those viral genomes have become inactivated, some copies of the most recently endogenized human retrovirus, HERV-K, can encode individual functional proteins. Here, we characterize the envelope protein (ENV) of the virus to define how it mediates infection of cells. We demonstrate that HERV-K ENV undergoes a proteolytic processing step and triggers membrane fusion in response to acidic pH--a strategy

higher than 0.5 wt. %. Investigation revealed that the Y rich phases were complex (W-Y) oxides formed during the sintering process. Also very interesting to use doping chromium with yttrium-containing alloys. e.g. (W - 10÷12 Cr -0.5÷2 Y) wt. %. The extent up to which yttrium acts as an active element improving the adherence and stability of the protective Cr 2 O 3 layer formed during oxidation is assessed. The structure and characteristics of the obtained samples depends on the phase content, distribution of phases and processing parameters during explosive synthesis and consolidation. Cu – (10-30%) W powder mixtures were formed into cylindrical rods using a hot shock wave consolidation (HSWC) process. Different type of Cu - W precursor composition containing 10, 20 and 30% of nanoscale W were consolidated near theoretical density under 900°C The loading intensity was under 10 GPa. The investigation showed that the combination of high temperatures (above 800°C) and two stage shock wave compression was beneficial to the consolidation of the W-Cu & W-Y composites, resulting in high densities, good integrity and good electronic properties.

The tank farm system also connects to a series of processing plants which generate radioactive and hazardous wastes. The primary functions of the tank farm system are to store, transfer, concentrate, and characterize radioactive and hazardous waste generated at Hanford, until the waste can be safely retrieved, processed and dispositioned. The systems provided by Project W-314 support the store and transfer waste functions. The system elements to be upgraded by Project W-314 are identified in Section 3.1

Asteroid families in the Cybele and Hungaria groups

Vinogradova, T.; Shor, V.

Asteroid families are fragments of some disrupted parent bodies. Planetary perturbations force the primarily close orbits to evolve. One of the main features of the orbit evolution is the long-period variation of the osculating elements, such as the inclination and eccentricity. Proper elements are computed by elimination of short- and long-period perturbations, and, practically, they do not change with time. Therefore, proper elements are important for family-identification procedures. The techniques of proper-element computation have improved over time. More and more accurate dynamical theories are developed. Contrastingly, in this work, an empirical method is proposed for proper-element calculations. The long-term variations of osculating elements manifest themselves very clearly in the distributions of pairs: inclination and longitude of ascending node; eccentricity and longitude of perihelion in the corresponding planes. Both of these dependencies have a nearly sinusoidal form for most asteroid orbits with regular motion of node and perihelion. If these angular parameters librate, then the sinusoids transform to some closed curve. Hence, it is possible to obtain forced elements, as parameters of curves specified above. The proper elements can be calculated by an elimination of the forced ones. The method allows to obtain the proper elements in any region, if there is a sufficient number of asteroids. This fact and the simplicity of the calculations are advantages of the empirical method. The derived proper elements include the short-period perturbations, but their accuracy is sufficient to search for asteroid families. The special techniques have been developed for the identification of the families, but over a long time large discrepancies took place between the lists of families derived by different authors. As late as 1980, a list of 30 reliable families was formed. And now the list by D. Nesvorny includes about 80 robust families. To date, only two

Full Text Available Soap operas are a cultural phenomenon of recognized importance in Brazilian society. They have come into the atention of investigators since they represent concrete social processes that are not strange to the spectator´s reality. A large variety of social themes have already been discussed in soap operas, characterizing a broad spectrum which covers from daily ordinary events up to controversial situation of rupture, forcing public debate. This investigation at empted to identify and analyze how family arrangements, as well as familial and conjugal daily routine, were portrayed in six soap opera plots exhibited between 2003 and 2008 by Rede Globo network. The data collection was performed by the analysis of the soap operas chapter synopses, and the data was organized and discussed using the classic content analysis technique. The way Brazilian family is portrayed in the weekly TV fiction incorporates new family arrangements, presenting new relationship construction possibilities originated during the last decades, in opposition to the conservative raditions

Finite elements are used to express the mechanical behaviour of a structure in finite element analysis. Therefore, the selection of the elements determines the quality of the analysis. The aim of this paper is to compare and contrast 1D element, 2D element, and 3D element used in finite element analysis. A simple case study was carried out on a standard W460x74 I-beam. The I-beam was modelled and analyzed statically with 1D elements, 2D elements and 3D elements. The results for the three separate finite element models were compared in terms of stresses, deformation and displacement of the I-beam. All three finite element models yield satisfactory results with acceptable errors. The advantages and limitations of these elements are discussed. 1D elements offer simplicity although lacking in their ability to model complicated geometry. 2D elements and 3D elements provide more detail yet sophisticated results which require more time and computer memory in the modelling process. It is also found that the choice of element in finite element analysis is influence by a few factors such as the geometry of the structure, desired analysis results, and the capability of the computer

W and W alloys containing 0.5 wt% Y{sub 2}O{sub 3}, x wt% Ti and (x wt% Ti + 0.5 wt% Y{sub 2}O{sub 3}) have been prepared, x = 2 or 4. Elemental powders were blended or ball milled, canned, degassed and finally consolidated by a two-stage HIP process under a pressure of 195 MPa. It is found that Ti addition favours the densification attaining a fully dense material. XRD, SEM and EDX analyses of the material with Ti addition reveal the formation of a microstructure consisting of tungsten particles embedded in a W-Ti matrix. The microhardness of these materials increased noticeably with the titanium content.

Von Neumann algebras M of bounded operators on self-dual Hilbert W* moduli H possessing a cyclic-separating element x-bar in H are considered. The close relation of them to certain real subspaces of H is established. Under the supposition that the underlying W*-algebra is commutative, a Tomita-Takesaki type theorem is stated. The natural cone in H arising from the pair (M, x-bar) is investigated and its properties are obtained

We present a manifestly N=2 supersymmetric formulation of N=2 super-W 3 algebra (its classical version) in terms of the spin 1 and spin 2 supercurrents. Two closely related types of the Feigin-Fuchs representation for these supercurrents are found: via two chiral spin 1/2 superfields generating N=2 extended U(1) Kac-Moody algebras and via two free chiral spin 0 superfields. We also construct a one-parameter family of N=2 super Boussinesq equations for which N=2 super-W 3 provides the second Hamiltonian structure. (author). 17 refs

The reflections were inspired by the blog of the Canadian photographer Rita Leistner, who participated in the media project aimed at familiarizing American soldiers’ families and friends with everyday life of the military contingent in Afghanistan. Leistner, for the first time in her career, used a smartphone instead of professional photographic equipment. Her decision was motivated by the need to edit photographs easily and publish them quickly on the Internet. The result of her work was a blog, titled Looking for Marshall McLuhan in Afghanistan. To describe her photographs, Leistner uses selected concepts defined by McLuhan in the second half of the 20th century: probe, extension of man or figure-background dichotomy. In consequence, the technological face of war can be better understood by the viewers of the materials she prepared.   Oblicza wojny w kontekście teorii mediów Marshalla McLuhana W artykule przedstawiono sposób wykorzystania teorii mediów Marshalla McLuhana do analizy zdjęć wykonanych iPhone’em.

In this study, a large-power inductively coupled plasma source was designed to perform the continuous helium ion irradiations of W-Cr binary alloy (W-20 wt%Cr) under relevant conditions of the International Thermonuclear Experimental Reactor. Surface damages and microstructures of irradiated W-20Cr were observed by using scanning electron microscopy, energy-dispersive X-ray spectroscopy, and transmission electron microscopy. The addition of Cr dramatically enhanced the micro-hardness of the obtained bulk materials, and the interface between the W matrix and the second phase Cr-O is a semi-coherent interface. After irradiation, the doping of Cr element effectively reduces the damage of the W matrix during the irradiation process. The semi-coherent interface between the second phase and the W matrix improves the anti-irradiation performance of the W-20Cr alloy.

Simultaneous qubit-loss-free fusion of three multiple W states

Wang, Meiyu; Hao, Quanzhi; Yan, Fengli; Gao, Ting

2018-05-01

Qubit-loss-free fusion for two W states introduced by Li K et al (2016 Phys. Rev. A 94 062315) clearly increases the final size of the obtained W state and greatly reduces the number of fusion steps to achieve a W state of a target size. Motivated by this idea, we propose a qubit-loss-free fusion scheme for fusing three polarization entangled W states simultaneously. The elements of a two-outcome positive-operator valued measurement and the appropriate joint unitary operation for realizing a positive-operator valued measurement measurement are given. As an example, with the assistance of weak cross-Kerr nonlinearities, an optical setup for fusing three W states is proposed. We analyze the success probability of the scheme and the resource cost of the present scheme, as compared to previous work.

Theoretical analysis of the alloying element effect on decarburization

International Nuclear Information System (INIS)

Elanskij, G.N.; Kudrin, V.A.; Akinfiev, S.I.

1978-01-01

On the basis of the laws of physical chemistry the alloying element (Ni, Cr, Mo, W, Co, Mn) effect on the kinetics and degree of decarburizing in iron melt with low carbon concentrations has been determined. The calculation of alloying element effect on the value of carbon diffusion coefficient and on the velocity changes in carbon oxidation rate has been carried out. It is shown that carbon diffusion coefficient and decarburization rate are detemined by two factors: thermodynamic, carbon activity change in the presence of alloying elements being accounted for and structural, dependending on the liquid metal structure and being determined by the viscosity activity of impurity. Experimental data are given, testifying that the introduction in the melt of such elements as Ni, Co, Cu, promotes a decrease in carbon content, as well as accelerates the decarburization process. W and Mo produce a poor effect, and Cr and Mn abruptly increase the value of minimum carbon content. Mo, Cr and W reduce the decarburization rate in the melt

This study aims to evaluate the distribution of K, Rb and Cs in leaves of trees of the Atlantic Forest through studies of correlation between the chemical elements. For this, we used the Instrumental Neutron Activation Analysis for the quantification of the chemical elements. The concentration ranges found were 6700-24000 mg / kg for K, 16 to 72mg / kg for Rb and 0.08 to 0,92mg / kg for Cs. As Rb has chemical similarity to K, is easily absorbed by plants, leading to a high value (0.9) of the Pearson correlation. For the correlation between K and Cs, no significant values were detected except for some species of the Myrtaceae family. However, average correlations (0.6 families. The absence of a specific pattern using of K, Rb and Cs by plants showed great complexity in the distribution of chemical elements in the ecosystem.

Full Text Available In the paper profilometric measurements of graphite casting elements were described. Basic topics necessary to assess roughness of their surfaces and influence of asperities on various properties related to manufacturing and use were discussed. Stylus profilometer technique of surface irregularities measurements including its limits resulting from pickup geometry and its contact with measured object were ana-lyzed. Working principle of tactile profilometer and phenomena taking place during movement of a probe on a measured surface were shown. One of the important aspects is a flight phenomenon, which means movement of a pickup without contact with a surface during inspection resulting from too high scanning speed. results of comparison research for graphite elements of new and used mould and pin composing a set were presented. Using some surface roughness, waviness and primary profile parameters (arithmetical mean of roughness profile heights Ra, biggest roughness profile height Rz, maximum primary profile height Pt as well as maximum waviness profile height Wt a possibility of using surface asperities parameters as a measure of wear of chill graphite elements was proved. The most often applied parameter is Ra, but with a help of parameters from W and P family it was shown, that big changes occur not only for roughness but also for other components of surface irregularities.

Correlation functions with fusion-channel multiplicity in W3 Toda field theory

Belavin, Vladimir; Estienne, Benoit; Foda, Omar; Santachiara, Raoul

2016-01-01

Current studies of W N Toda field theory focus on correlation functions such that the W N highest-weight representations in the fusion channels are multiplicity-free. In this work, we study W 3 Toda 4-point functions with multiplicity in the fusion channel. The conformal blocks of these 4-point functions involve matrix elements of a fully-degenerate primary field with a highest-weight in the adjoint representation of sl 3 , and a fully-degenerate primary field with a highest-weight in the fundamental representation of sl 3 . We show that, when the fusion rules do not involve multiplicities, the matrix elements of the fully-degenerate adjoint field, between two arbitrary descendant states, can be computed explicitly, on equal footing with the matrix elements of the semi-degenerate fundamental field. Using null-state conditions, we obtain a fourth-order Fuchsian differential equation for the conformal blocks. Using Okubo theory, we show that, due to the presence of multiplicities, this differential equation belongs to a class of Fuchsian equations that is different from those that have appeared so far in W N theories. We solve this equation, compute its monodromy group, and construct the monodromy-invariant correlation functions. This computation shows in detail how the ambiguities that are caused by the presence of multiplicities are fixed by requiring monodromy-invariance.

Full Text Available Efficient functioning of a re-socialization institution is a condition of its growth and key factor of appropriate course of the community life that within its structure. Its efficiency relies on explicitly, clearly acknowledged objectives, its internal organization and division of workload as well as the independence of the professional tasks from the personal interests of the staff. Moreover, it tackles the conformity of the staff aspirations with aims and assignments for the accomplishment of which such a structure has been established, entailing high internal integrity, productive cooperation with other facilities and the external environment. It enables the achievement of the projected and socially desired outcomes as well as the accomplishment of common goals upon arrangements of various activities. Cooperation with the family environment of the charges constitutes a key element of the functionality of every re-socialization institution. It must be remembered that parents of the juvenile delinquents manifest features disabling the appropriate course of the upbringing, which consequently can lead to the children’s criminogenic lifestyle. Such features concern structural properties of the families, qualities related to the emotional attitude to their child, parental competences and last but not least – upbringing methods. Non-structural features can be subject to modification in given circumstances. Nonetheless, it is a challenging task particularly when institutions do not participate in the process of family support. Inclusion of the charges’ parents in the process of its correctional activities can condition the quality of educational measures accomplished within, becoming a key indicator of a rational organization and correction of behavior, reforming socially maladjusted behaviors of children and teenagers.

Vaccination directed against the human endogenous retrovirus-K envelope protein inhibits tumor growth in a murine model system.

Human endogenous retrovirus (HERV) genomes are chromosomally integrated in all cells of an individual. They are normally transcriptionally silenced and transmitted only vertically. Enhanced expression of HERV-K accompanied by the emergence of anti-HERV-K-directed immune responses has been observed in tumor patients and HIV-infected individuals. As HERV-K is usually not expressed and immunological tolerance development is unlikely, it is an appropriate target for the development of immunotherapies. We generated a recombinant vaccinia virus (MVA-HKenv) expressing the HERV-K envelope glycoprotein (ENV), based on the modified vaccinia virus Ankara (MVA), and established an animal model to test its vaccination efficacy. Murine renal carcinoma cells (Renca) were genetically altered to express E. coli beta-galactosidase (RLZ cells) or the HERV-K ENV gene (RLZ-HKenv cells). Intravenous injection of RLZ-HKenv cells into syngenic BALB/c mice led to the formation of pulmonary metastases, which were detectable by X-gal staining. A single vaccination of tumor-bearing mice with MVA-HKenv drastically reduced the number of pulmonary RLZ-HKenv tumor nodules compared to vaccination with wild-type MVA. Prophylactic vaccination of mice with MVA-HKenv precluded the formation of RLZ-HKenv tumor nodules, whereas wild-type MVA-vaccinated animals succumbed to metastasis. Protection from tumor formation correlated with enhanced HERV-K ENV-specific killing activity of splenocytes. These data demonstrate for the first time that HERV-K ENV is a useful target for vaccine development and might offer new treatment opportunities for diverse types of cancer.

Bosonization of non-relativistic fermions and W-infinity algebra

Das, S.R.; Dhar, A.; Mandal, G.; Wadia, S.R.

1992-01-01

In this paper the authors discuss the bosonization of non-relativistic fermions in one-space dimension in terms of bilocal operators which are naturally related to the generators of W-infinity algebra. The resulting system is analogous to the problem of a spin in a magnetic field for the group W-infinity. The new dynamical variables turn out to be W-infinity group elements valued in the coset W-infinity/H where H is a Cartan subalgebra. A classical action with an H gauge invariance is presented. This action is three-dimensional. It turns out to be similar to the action that describes the color degrees of freedom of a Yang-Mills particle in a fixed external field. The authors also discuss the relation of this action with the one recently arrived at in the Euclidean continuation of the theory using different coordinates

Parenting in 2 Worlds (P2W) is a culturally grounded parenting intervention that addresses the distinctive social and cultural worlds of urban American Indian (AI) families. P2W was culturally adapted through community-based participatory research in three urban AI communities with diverse tribal backgrounds. This paper reports the immediate outcomes of P2W in a randomized controlled trial, utilizing data from 575 parents of AI children (ages 10–17). Parents were assigned to P2W or to the comparison group, an informational family health curriculum, Healthy Families in 2 Worlds (HF2W). Both the P2W and HF2W curricula consisted of 10 workshops delivered weekly by AI community facilitators. Pretests were administered at the first workshop and a post-test at the last workshop. Tests of the efficacy of P2W versus HF2W on parenting skills and family functioning were analyzed with pairwise t-tests, within intervention type, and by baseline adjusted path models using FIML estimation in Mplus. Intervention effect sizes were estimated with Cohen’s d. Participants in P2W reported significant improvements in parental agency, parenting practices, supervision and family cohesion, and decreases in discipline problems and parent-child conflict. Compared to HF2W, P2W participants reported significantly larger increases in parental self-agency and positive parenting practices, and fewer child discipline problems. Most of these desired program effects for P2W approached medium size. Culturally adapted parenting interventions like P2W can effectively strengthen parenting practices and family functioning among urban AI families and help address their widespread need for targeted, culturally grounded programs.

The Outer Membrane Protein OmpW Forms an Eight-Stranded beta-Barrel with a Hydrophobic Channel

International Nuclear Information System (INIS)

Hong, H.; Patel, D.; Tamm, L.; van den Berg, B.

2006-01-01

Escherichia coli OmpW belongs to a family of small outer membrane (OM) proteins that are widespread in Gram-negative bacteria. Their functions are unknown, but recent data suggest that they may be involved in the protection of bacteria against various forms of environmental stress. In order to gain insight into the function of these proteins we have determined the crystal structure of Escherichia coli OmpW to 2.7 Angstroms resolution. The structure shows that OmpW forms an eight-stranded beta-barrel with a long and narrow hydrophobic channel that contains a bound LDAO detergent molecule. Single channel conductance experiments show that OmpW functions as an ion channel in planar lipid bilayers. The channel activity can be blocked by the addition of LDAO. Taken together, the data suggest that members of the OmpW family could be involved in the transport of small hydrophobic molecules across the bacterial OM

Current studies of W{sub N} Toda field theory focus on correlation functions such that the W{sub N} highest-weight representations in the fusion channels are multiplicity-free. In this work, we study W{sub 3} Toda 4-point functions with multiplicity in the fusion channel. The conformal blocks of these 4-point functions involve matrix elements of a fully-degenerate primary field with a highest-weight in the adjoint representation of sl{sub 3}, and a fully-degenerate primary field with a highest-weight in the fundamental representation of sl{sub 3}. We show that, when the fusion rules do not involve multiplicities, the matrix elements of the fully-degenerate adjoint field, between two arbitrary descendant states, can be computed explicitly, on equal footing with the matrix elements of the semi-degenerate fundamental field. Using null-state conditions, we obtain a fourth-order Fuchsian differential equation for the conformal blocks. Using Okubo theory, we show that, due to the presence of multiplicities, this differential equation belongs to a class of Fuchsian equations that is different from those that have appeared so far in W{sub N} theories. We solve this equation, compute its monodromy group, and construct the monodromy-invariant correlation functions. This computation shows in detail how the ambiguities that are caused by the presence of multiplicities are fixed by requiring monodromy-invariance.

Optimum values of average L-shell fluorescence yields for the elements 40 ≤ Z ≤ 95

1993-01-01

The optimum values of average L-shell fluorescence yields W L , for elements 40 ≤ Z ≤ 95 have been determined using seven sets of experimental and theoretical values of W L reported by various workers. The first and second sets comprise of values of W L evaluated from L X-ray emission cross-sections measured for 22 elements by Mann and for 27 elements by Singh et al respectively. The third set contains most reliable experimental values compiled by Bombynek et al. In the remaining four sets the values of W L calculated from the semi empirical and theoretical values of L-subshell fluorescence yields W 1 and Coster-Kronig transition probabilities (f ij ) and photoionisation and proton induced ionisation cross sections are reported. All the values of W L for a given element reported in different sets are not same and for some elements the values differ from one another by more than 15%. The optimum value of W L for each element amongst the seven values is taken as a mean of group of those values whose standard deviation is almost less than 3% of the mean value. The optimum values are further fitted to the standard cubic form and the coefficients of the fit are a 0 = 0.3542371, a 1 =-0.489949E-02, a 2 0.2052273E-03 and a 3 =-0.8144938E-06. The values thus generated agree with optimum values within nearly 2%. (author). 10 refs., 1 tab

Time as an integrating factor in a family in foreign researches

Directory of Open Access Journals (Sweden)

Gorodilina M.V.

2017-03-01

Full Text Available The article provides an overview of foreign researches examining family relationships as presented in the family members’ memory. The researches regard the family as a social group represented by the nuclear family’s interpersonal relationships, as well as inter-generational relationships, which determines the mechanism and the establishment of its identity. The family is considered a complex unity of "systems in time". The article describes foreign experience of studying the concepts of family time by analyzing family narratives and autobiographical material. The methods professionals use to study the family time and the involvement of everyone in active construction of family history texts, family practices and rituals of socio-psychological value, are explained in the article. The methodologies of the following questionnaires were analyzed: “The family routines inventory” by E.W. Jensen, S.A. James, W.T. Boyce and S.A. Hartnett; “The family ritual questionnaire” by B.H. Fiesea and C.A. Kline; “Family time questionnaire” by A.S. Ellington.

Inert-Gas Condensed Co-W Nanoclusters: Formation, Structure and Magnetic Properties

Science.gov (United States)

Golkar-Fard, Farhad Reza

Rare-earth permanent magnets are used extensively in numerous technical applications, e.g. wind turbines, audio speakers, and hybrid/electric vehicles. The demand and production of rare-earth permanent magnets in the world has in the past decades increased significantly. However, the decrease in export of rare-earth elements from China in recent time has led to a renewed interest in developing rare-earth free permanent magnets. Elements such as Fe and Co have potential, due to their high magnetization, to be used as hosts in rare-earth free permanent magnets but a major challenge is to increase their magnetocrystalline anisotropy constant, K1, which largely drives the coercivity. Theoretical calculations indicate that dissolving the 5d transition metal W in Fe or Co increases the magnetocrystalline anisotropy. The challenge, though, is in creating a solid solution in hcp Co or bcc Fe, which under equilibrium conditions have negligible solubility. In this dissertation, the formation, structure, and magnetic properties of sub-10 nm Co-W clusters with W content ranging from 4 to 24 atomic percent were studied. Co-W alloy clusters with extended solubility of W in hcp Co were produced by inert gas condensation. The different processing conditions such as the cooling scheme and sputtering power were found to control the structural state of the as-deposited Co-W clusters. For clusters formed in the water-cooled formation chamber, the mean size and the fraction crystalline clusters increased with increasing power, while the fraction of crystalline clusters formed in the liquid nitrogen-cooled formation chamber was not as affected by the sputtering power. For the low W content clusters, the structural characterization revealed clusters predominantly single crystalline hcp Co(W) structure, a significant extension of W solubility when compared to the equilibrium solubility, but fcc Co(W) and Co3W structures were observed in very small and large clusters, respectively.

Full Text Available W pracy przedstawiono analizę wyników badań hydrochemicznych, którymi objęto źródła występujące na terenie Ojcowskiego Parku Narodowego. W terenie zinwentaryzowano 19 źródeł, w tym 10 w Dolinie Sąspowskiej i 9 w Dolinie Prądnika. Wszystkie źródła w Dolinie Sąspowskiej posiadają naturalne misy, natomiast w Dolinie Prądnika misy 7 źródeł zostały częściowo lub całkowicie zabudowane przez człowieka. Podczas prac terenowych zmierzono wydajność źródeł oraz temperaturę wody, pH, przewodność elektrolityczną i potencjał redoks, a w laboratorium oznaczono stężenia kilkunastu jonów, w tym makro- i mikroelementów oraz związków biogennych. Na podstawie badań stwierdzono, że w OPN dominują źródła o wydajność od 1 do 10 dm3 · s–1. Ze źródeł wypływa woda prosta dwujonowa wodorowęglanowo-wapniowa, o odczynie słabo zasadowym. Na podstawie klasyfikacji badanych elementów fizykochemicznych zaliczono je do klasy II, czyli wód o dobrej jakości. W wodzie wszystkich źródeł stwierdzono podwyższone stężenie wodorowęglanów, wapnia oraz azotanów, co jest prawdopodobnie wynikiem naturalnych procesów zachodzących w wodach podziemnych i nie wskazuje na wpływ działalności człowieka, albo jest to wpływ bardzo słaby.

Behavior of a VVER fuel element tested under severe accident conditions in the CORA facility. Test results of experiment CORA-W1

Test bundle CORA-W1 was without absorber material. As in the earlier CORA tests the test bundles were subjected to temperature transients of a slow heatup rate in a steam environment. The transient phases of the test were initiated with a temperature ramp rate of 1 K/s. With these conditions a so-called small-break LOCA was simulated. The temperature escalation due to the exothermal zirconium/niobium-steam reaction started at about 1200 C, leading the bundle to a maximum temperature of approximately 1900 C. With the movement of the melt also heat is transported to the lower region. Below 300 mm elevation the test bundle remained intact due to the axial temeprature distribution. W2 ist characterized by a strong oxidation above 300 mm elevation. Besides the severe oxidation the test bundle resulted in considerable fuel dissolution by ZrNb1/UO 2 interaction in the upper part, complete spacer destruction at 600 mm due to chemical interactions between steel and the ZSrNb1 cladding. Despite some specific features the material behavior of the VVER-1000 bundle is comparable to that observed in the PWR and BWR test using fuel elements typical for Western countries. (orig./HP) [de

Making a virtue of necessity: the pleiotropic role of human endogenous retroviruses in cancer.

Kassiotis, George; Stoye, Jonathan P

2017-10-19

Like all other mammals, humans harbour an astonishing number of endogenous retroviruses (ERVs), as well as other retroelements, embedded in their genome. These remnants of ancestral germline infection with distinct exogenous retroviruses display various degrees of open reading frame integrity and replication capability. Modern day exogenous retroviruses, as well as the infectious predecessors of ERVs, are demonstrably oncogenic. Further, replication-competent ERVs continue to cause cancers in many other species of mammal. Moreover, human cancers are characterized by transcriptional activation of human endogenous retroviruses (HERVs). These observations conspire to incriminate HERVs as causative agents of human cancer. However, exhaustive investigation of cancer genomes suggests that HERVs have entirely lost the ability for re-infection and thus the potential for insertional mutagenic activity. Although there may be non-insertional mechanisms by which HERVs contribute to cancer development, recent evidence also uncovers potent anti-tumour activities exerted by HERV replication intermediates or protein products. On balance, it appears that HERVs, despite their oncogenic past, now represent potential targets for immune-mediated anti-tumour mechanisms.This article is part of the themed issue 'Human oncogenic viruses'. © 2017 The Authors.

Genetic sex-determining systems in vertebrates include two basic types of heterogamety; XX (female)/XY (male) and ZZ (male)/ZW (female) types. The African clawed frog Xenopus laevis has a ZZ/ZW-type sex-determining system. In this species, we previously identified a W-specific sex (female)-determining gene dmw, and specified W and Z chromosomes, which could be morphologically indistinguishable (homomorphic). In addition to dmw, we most recently discovered two genes, named scanw and ccdc69w, and one gene, named capn5z in the W- and Z-specific regions, respectively. In this study, we revealed the detail structures of the W/Z-specific loci and genes. Sequence analysis indicated that there is almost no sequence similarity between 278kb W-specific and 83kb Z-specific sequences on chromosome 2Lq32-33, where both the transposable elements are abundant. Synteny and phylogenic analyses indicated that all the W/Z-specific genes might have emerged independently. Expression analysis demonstrated that scanw and ccdc69w or capn5z are expressed in early differentiating ZW gonads or testes, thereby suggesting possible roles in female or male development, respectively. Importantly, the sex-determining gene (SDG) dmw might have been generated after allotetraploidization, thereby indicating the construction of the new sex-determining system by dmw after species hybridization. Furthermore, by direct genotyping, we confirmed that diploid WW embryos developed into normal female frogs, which indicate that the Z-specific region is not essential for female development. Overall, these findings indicate that sex chromosome differentiation has started, although no heteromorphic sex chromosomes are evident yet, in X. laevis. Homologous recombination suppression might have promoted the accumulation of mutations and transposable elements, and enlarged the W/Z-specific regions, thereby resulting in differentiation of the W/Z chromosomes.

Full Text Available Family Health (FH has three main elements: individual health, life material conditions and family functioning. Its main actors are the individual, the family and society. A common framework is the basis of FH, as each one of these elements is extremely important. Currently, in Mexico two aspects are considered: epidemiological studies and those inherent to the family medicine specialty. That latter has a residency and an integrated specialty curriculum, as well as certification from the corresponding board. All of this allows us to apply the HF approach to each and every family and individual that is cared for.

Martwica kości szczęk związana ze stosowaniem bifosfonianów. Opis przypadków

Full Text Available Bifosfoniany należą do silnych inhibitorów osteoklastów. Znajdują szerokie zastosowanie w leczeniu chorób przebiegających ze wzmożoną resorpcją kości: osteoporozy, choroby Pageta i osteogenesis imperfecta. Leki te zmniejszają adhezję komórek nowotworowych do kości, ograniczają osteolizę wywołaną nowotworem i hiper‑ kalcemię. Zmniejszają dolegliwości bólowe w szpiczaku mnogim i w przerzutach do kości. Powszechnie panu‑ jące przekonanie o bezpieczeństwie spowodowało rozszerzenie wskazań do ich stosowania. Pacjenci onkolo‑ giczni przyjmujący bifosfoniany dożylnie, w wysokich dawkach są bardziej narażeni na działania niepożądane terapii niż pacjenci przyjmujący je doustnie. Jednym z najpoważniejszych powikłań jest martwica kości szczęk. W 2003 roku opisano po raz pierwszy związek pomiędzy terapią bifosfonianami a martwicą kości szczęk. W piśmiennictwie znajdujemy coraz więcej przykładów tego działania niepożądanego, także po stosowaniu leków doustnie. Mogą pojawiać się ból, obrzęk, owrzodzenie, odsłonięcie kości, przetoki, złamania patologiczne, uciążliwe dla pacjenta i obniżające jakość życia. Leczenie martwicy kości szczęk jest trudne i rzadko przynosi spodziewany efekt. Główną rolę odgrywa leczenie zachowawcze i redukcja objawów. Odstawienie bifosfonia‑ nów nie ma bezpośredniego wpływu na przebieg martwicy kości szczęk, ze względu na kumulację leku w kości. Istotne jest przygotowanie pacjenta przed rozpoczęciem podawania bifosfonianów, wymagające stałej współ‑ pracy pomiędzy lekarzami onkologami, ortopedami i chirurgami szczękowo-twarzowymi. Higiena jamy ustnej i leczenie chorób współistniejących stanowi ważny element postępowania. Celem pracy jest przedstawienie trzech przypadków martwicy kości szczęk u pacjentów poddanych leczeniu bifosfonianami.

The production of W+W- pairs is analysed in a data sample collected by ALEPH at a mean centre-of-mass energy of 182.7 GeV, corresponding to an integrated luminosity of 57 pb-1. Cross sections are given for different topologies of W decays into leptons or hadrons. Under Standard Model assumptions for the W-pair production and decay, the W-pair cross section is measured to be 15.57+-0.62(stat.)+-0.29(syst.) pb. Using also the W-pair data samples collected by ALEPH at lower centre-of-mass energies, the decay branching ratio of the W boson into hadrons is measured to be B(W->hadrons)= 68.93+-1.21(stat.)+-0.51(syst.)%, allowing a determination of the CKM matrix element |Vcs|= 1.043 +- 0.058(stat.) +- 0.026(syst.). The agreement of the cross sections with the Standard Model prediction allows a limit to be set on the W decay rate to undetectable final states.

Relationships in the Coda (Child of deaf adult family [Relacje w rodzinie CODA

Full Text Available Human existence is accompanied by attempts at self understanding, finding one’s place in the world and a way to co-exist with other people. The very unique social and family situation of the hearing children of deaf parents allows the trials of clarification of what characterizes and distingishes them as Codas. The childhood, adolescence and adult life of Codas is definitely different than the lives of people living in hearing families. In the family in which one or both parents are deaf it is very likely that the way they are functioning will have consequences for their hearing childrens' future functioning. There are aspects of family life that have influence on this disguised difference, such as: forms of communication, pantomimic gestures, mimics and also the characteristic phenomena of family roles reversal. The relations in Codas untypical families are determined by multiple factors. Among them mutual understanding which, with the help of values presented and applied in the process of upbringing, is one of the most important as it may result, in the right circumstances, in achieving a unique family union. The forming of emotional bonds between deaf parents and their children is influenced by, for example fulfilling the need of love in the family house and the adequate use of situations which favour communication. Usually the perspective of time makes adult Codas more tolerant and fully understanding of the obligations assigned to them by deaf parents during their childhood and adolescence. Being a Coda each time is related to individual life situations in which some Codas may find themselves happy and fulfilled while others won’t .

wACSF—Weighted atom-centered symmetry functions as descriptors in machine learning potentials

We introduce weighted atom-centered symmetry functions (wACSFs) as descriptors of a chemical system's geometry for use in the prediction of chemical properties such as enthalpies or potential energies via machine learning. The wACSFs are based on conventional atom-centered symmetry functions (ACSFs) but overcome the undesirable scaling of the latter with an increasing number of different elements in a chemical system. The performance of these two descriptors is compared using them as inputs in high-dimensional neural network potentials (HDNNPs), employing the molecular structures and associated enthalpies of the 133 855 molecules containing up to five different elements reported in the QM9 database as reference data. A substantially smaller number of wACSFs than ACSFs is needed to obtain a comparable spatial resolution of the molecular structures. At the same time, this smaller set of wACSFs leads to a significantly better generalization performance in the machine learning potential than the large set of conventional ACSFs. Furthermore, we show that the intrinsic parameters of the descriptors can in principle be optimized with a genetic algorithm in a highly automated manner. For the wACSFs employed here, we find however that using a simple empirical parametrization scheme is sufficient in order to obtain HDNNPs with high accuracy.

Full Text Available Kin term patterns and language familie The anthropologist G. P. Murdock has found a strong correlation between the kin term patterns (or feature-values for the relative (feature “sibling” and language families. This important finding for language classification, however, has not been pursued further. In particular, it has not yet been tested whether the kin term patterns domain as a whole, including the patterns for other features (“grandparents”, “uncles”, “aunts”, “nephews and nieces”, etc., is sufficient to demarcate all language families from one another. This paper presents a large-scale computational profiling of all language families in terms of their kin term patterns. The most significant findings are: (i that language families can be quite neatly differentiated on the basis of their kin term patterns, and therefore these patterns may be considered as strong indicators of genetic affiliation, and (ii that the kin term patterns for the features “nephews and nieces (= siblings' children”, “siblings”, and “siblings-in-law” — i.e. all features including the idea of siblings — are the best predictors of genetic affiliation, as they are significantly more frequently used in the profiles than any other feature.    Modele terminologii powinowactwa i pokrewieństwa a rodzina językowa Antropolog G.

To examine the effect of neutron transmutation on tungsten as the first wall material of fusion reactors, the elastic properties of W 1-x-y  Re x  Os y (0  ⩽  x, y  ⩽  6%) random alloys in body centered cubic (bcc) structure are investigated systematically using the all-electron exact muffin-tin orbitals (EMTO) method in combination with the coherent-potential approximation (CPA). The calculated lattice constant and elastic properties of pure W are consistent with available experiments. Both Os and Re additions reduce the lattice constant and increase the bulk modulus of W, with Os having the stronger effect. The polycrystalline shear modulus, Young's modulus and the Debye temperature increase (decrease) with the addition of Re (Os). Except for C 11 , the other elastic parameters including C 12 , C 44 , Cauchy pressure, Poisson ratio, B/G, increase as a function of Re and Os concentration. The variations of the latter three parameters and the trend in the ratio of cleavage energy to shear modulus for the most dominant slip system indicate that the ductility of the alloy enhances with increasing Re and Os content. The calculated elastic anisotropy of bcc W slightly increases with the concentration of both alloying elements. The estimated melting temperatures of the W-Re-Os alloy suggest that Re or Os addition will reduce the melting temperature of pure W solid. The classical Labusch-Nabarro model for solid-solution hardening predicts larger strengthening effects in W 1-y  Os y than in W 1-x  Re x . A strong correlation between C' and the fcc-bcc structural energy difference for W 1-x-y  Re x  Os y is revealed demonstrating that canonical band structure dictates the alloying effect on C'. The structural energy difference is exploited to estimate the alloying effect on the ideal tensile strength in the [0 0 1] direction.

Full Text Available The evolution of dog’s view in Polish language The article presents the evolution of dog’s view in Polish language within the centuries – from Old Polish to the present, considering vocabulary dialect. The components of a dichotomous present stereotype of dog (the two negative ones and one positive are analyzed in the work. The negative ones seem to belong to the older structure of the language. The example of association with “a lie” – in Polish łże jak pies – and its metaphorical meaning of the verb, is well-known from the Old Polish and still used, however, less frequent. The phenomenon seems to be similar to the attributing a dog with its small value, as it is documented in the used meanings of adjectives such as: psi / pieski (‘dog-ass’. Late testified, but extremely important element of the dog’s view, is associating it with dog’s fidelity that was expressed in a phrase wierny jak pies – that is focused on being a faithful dog. This combination of two meanings resulting in its dichotomy, and even its internal contradiction, rejected the negative stereotype of a dog. Nowadays, due to the cultural changes including our attitude to animals generally, especially domestic ones, its primary association with fidelity seems to be priority.

Transposable elements (TEs) are present in most of the eukaryotic genomes and their impact on genome evolution is increasingly recognized. Although there is extensive information on the TEs present in several eukaryotic genomes, less is known about the expression of these elements at the transcriptome level. Here we present a detailed analysis regarding the expression of TEs in Anopheles funestus, the second most important vector of human malaria in Africa. Several transcriptionally active TE families belonging both to Class I and II were identified and characterized. Interestingly, we have identified a full-length putative active element (including the presence of full length TIRs in the genomic sequence) belonging to the hAT superfamily, which presents active members in other insect genomes. This work contributes to a comprehensive understanding of the landscape of transposable elements in A. funestus transcriptome. Our results reveal that TEs are abundant and diverse in the mosquito and that most of the TE families found in the genome are represented in the mosquito transcriptome, a fact that could indicate activity of these elements.The vast diversity of TEs expressed in A. funestus suggests that there is ongoing amplification of several families in this organism.

Mycobacterium yongonense, as a novel member of the M. avium complex (MAC), was recently reported to be isolated from human specimens in South Korea and Italy. Due to its close relatedness to other MAC members, particularly M. intracellulare in taxonomic aspects, the development of a novel diagnostic method for its specific detection is necessary for clinical or epidemiologic purposes. Using the Mycobacterium yongonense genome information, we have identified a novel IS-element, ISMyo2. Targeting the ISMyo2 sequence, we developed a real-time PCR method and applied the technique to Mycobacterial genomic DNA. To identify proper nucleic acid targets for the diagnosis, comparisons of all insertion sequence (IS) elements of 3 M. intracellulare and 3 M. yongonense strains, whose complete genome sequences we reported recently, led to the selection of a novel target gene, the M. yongonense-specific IS element, ISMyo2 (2,387 bp), belonging to the IS21 family. Next, we developed a real-time PCR method using SYBR green I for M. yongonense-specific detection targeting ISMyo2, producing a 338-bp amplicon. When this assay was applied to 28 Mycobacterium reference strains and 63 MAC clinical isolates, it produced amplicons in only the 6 M. yongonense strains, showing a sensitivity of 100 fg of genomic DNA, suggesting its feasibility as a diagnostic method for M. yongonense strains. We identified a novel ISMyo2 IS element belonging to the IS21 family specific to M. yongonense strains via genome analysis, and a real-time PCR method based on its sequences was developed.

The nation as community of culture is in opinion of the said parties exposed to dangers. The main risks are in their opinion as follows: cosmopolitism, Communist ideology, individualism, liberalism; secularization.In Poland, such ideas are, in the opinion of the National Right Wing, propagated by the liberal and post-communist circles. In the beginning they demanded that the communist activists are brought to justice. Some columnists refer to antisemitism. They perceive also the fall of the literary output. They assess critically the novels of Czesław Miłosz, Stanisław Barańczak or Olga Tokarczuk. Similar assessments regard the works of Polish historians. As preventive measures the following is mentioned: appropriate educational activity, statutory protection of national heritage, broadening of Catholicism, promotion of national culture. They attach great importance to the national branding. Its components are history, language, political regime, architecture, literature, art, religion, icons landscape, music. They would probably accept the opinion of Michael Porter: “Many contemporary discussions of international competition stress global homogenization and a diminished role for nations.

We discuss production of W + W - pairs in proton-proton collisions induced by two-photon fusion including, for a first time, transverse momenta of incoming photons. The unintegrated inelastic fluxes (related to proton dissociation) of photons are calculated based on modern parametrizations of deep inelastic structure functions in a broad range of their arguments ( x and Q 2). In our approach we can get separate contributions of different W helicities states. Several one- and two-dimensional differential distributions are shown and discussed. The present results are compared to the results of previous calculations within collinear factorization approach. Similar results are found except of some observables such as e.g. transverse momentum of the pair of W + and W -. We find large contributions to the cross section from the region of large photon virtualities. We show decomposition of the total cross section as well as invariant mass distribution into the polarisation states of both W bosons. The role of the longitudinal F L structure function is quantified. Its inclusion leads to a 4-5% decrease of the cross section, almost independent of M WW .

Full Text Available The article covers the issues of family functioning as one-child and multi-child families from the perspective of the children of these family systems. A family model of 2 + 1 is currently preferred while certain doubts are associated with families with many children in assuming that they often live at a lower level . Most frequently in one-child families the child is the centre of attention and occupies a privileged position. On the other hand to be the only child is associated with fewer interactions within the family, as well as a limitation of the amount of roles in the family. Parents usually are excessively focused on their child, overly protect him and have too high expectations of him. More often in these families there is emphasis on stimulating the child in the intellectual sphere. In the case of large families a lot depends on how the family consciously and responsibly decide about the family interractions. Children functioning in large families more often can adapt to the changing conditions of life, they are able to face various difficulties and have more experience in establishing relationships with others. The aim of our research was to determine how the children from single-child and multi-child families, assess the situation in the family. It analyzed the relationships in families, depending on the number of offspring, what is the level of consistency in the relationship ties between individual family members and the level of adaptability, namely the ability to make changes in the family. A questionnaire of our own design was used at the study, Family Adaptability and Cohesion Scales and Parent-Adolescent Communication Scales D.H. Olson and associates. The situation in the family has been evaluated by 120 grammar school students, including 60 who were the only child and 60 people from large families. Studies have shown that in many aspects, both families with one child and multi-child families are functioning properly. However

Full Text Available Obserwowany wzrost temperatury powietrza na półkuli północnej, zwłaszcza w Europie, może prowadzić do znacznych zmian w fenologii roślin, a w konsekwencji także w produkcji rolnej. Celem pracy jest ocena zróżnicowania przestrzennego zasobów termicznych na obszarze Polski oraz ich zmienności w okresie 1951–2010 w obliczu zmieniających się warunków termicznych. Analizę przeprowadzono z wykorzystaniem dobowych wartości temperatury powietrza. Zasoby termiczne zdefiniowane zostały za pomocą sum temperatur efektywnych (Growing Degree Days – GDD obliczonych dla wartości progowych temperatury powietrza: 0°C, 5°C i 10°C. Następstwem analizy zróżnicowania przestrzennego zasobów termicznych była ocena ich zmienności wieloletniej oraz tendencji zmian. Badania objęły w szczególności regiony sadownicze odznaczające się największą powierzchnią upraw drzew owocowych oraz wielkością zbiorów jabłek, śliw i wiśni. Uzyskane wyniki potwierdzają zwiększenie zasobów termicznych na obszarze kraju, będące konsekwencją wydłużającego się okresu wegetacyjnego.

Full Text Available Zastosowanie tworzyw sztucznych jako materiału do budowy instalacji wymusiło konieczność weryfikacji dostępnych obecnie informacji dotyczących wartości współczynników oporów lokalnych, które stanowią niezbędną wiedzę potrzebną do obliczania wartości strat energii mechanicznej, jakie powstają w trakcie przepływu. Współczynniki te mają duże znaczenie w obliczeniach hydraulicznych wymiarowanej instalacji. Wpływają one na końcowy wynik w istotny sposób, dlatego nieprawidłowe ich przyjęcie może prowadzić do poważnych w skutkach błędów. Niestety wartości podawane przez producentów, normy czy też literaturę są inne w porównaniu z wartościami uzyskiwanymi metodą doświadczalnych badań. W artykule zaprezentowane zostały wyniki badań doświadczalnych, mających na celu wyznaczenie wartości współczynników oporów lokalnych na kolankach 90° trzech określonych średnic, pochodzących od czterech wybranych producentów systemów instalacyjnych. Otrzymane wartości współczynników oporów lokalnych porównano z wartościami, jakie podawane są przez producenta złączek, wyznaczonymi według normy PN-76/M-34034: 1976 oraz dostępnymi w literaturze przedmiotu.

A study of W+W- events accomanied by hard photon radiation produced in e+e- collisions at LEP is presented. Events consistent with being two on-shell W bosons and an isolated photon are selected from 681 pb^-1 of data recorded at 180 GeV < sqrt(s) < 209 GeV. For these data , 187 W+W- candidates are selected with photon energies greater than 2.5 GeV. The selected events are used to determine the W+ W- gamma cross section at five values of sqrt(s). The results are consistent with the Standard Model expectation. These data provide constraints on the related O(alpha) systematic uncertainties on the measurement of the W boson mass at LEP. Finally, the data are used to derive 95% C.L. upper limits on possible anomalous contributions to the W+ W- gamma gamma and W+ W- Z0 gamma vertices.

  Streszczenie   Edukacja pacjentów z astmą jest jednym z elementów warunkujących osiąganie celów leczenia, a w konsekwencji poprawia jakość życia chorych. Pośród wielu czynników warunkujących skuteczność edukacji prowadzonej wobec pacjentów z chorobą przewlekłą i / lub ich opiekunów na szczególną uwagę zasługują: partnerskie relacje między lekarzem a pacjentem/ jego opiekunem, dostosowanie zakresu wiedzy w zależności do wieku, poziomu wykształcenia oraz oczekiwań pacjentów/ opiekunów.  Istotna też jest ciągłość kształcenia, mająca na celu weryfikację zdobytej wiedzy  i nabytych umiejętności.  Chory na astmę musi zaakceptować chorobę i z pełnym przekonaniem podjąć zadanie współuczestnictwa w jej leczeniu. Edukacja jest podstawą interakcji między pracownikami opieki zdrowotnej a pacjentem. Może mieć charakter edukacji bezpośredniej,  szkoleń w małych grupach, seminariów, sympozjów, konferencji, dystrybucji materiałów edukacyjnych, kampanii medialnych,  portali internetowych.   Abstract   Education of patients with asthma is one of the prerequisites for achieving the goals of treatment and consequently improves the quality of life of patients. Among the many factors determining the effectiveness of education provided to patients with chronic disease and / or their carers deserve special attention: partnerships between doctor and patient / his guardian, adjust the scope of knowledge according to age, educational level and expectations of patients / caregivers. Also important is the continuity of education, in order to verify their knowledge and acquired skills. Suffering from asthma must accept the disease and confidently take on the task of participation in its treatment. Education is the basis of the interaction between health care professionals and patients. It may be of direct education, training in small groups, seminars, symposia, conferences, distribution of educational materials, media

Nine PHWR type fuel elements with reduced length were irradiated in loop A of the TRIGA Research Reactor of INR Pitesti. The primary objective of the test was to determine the performance of nuclear fuel fabricated at INR Pitesti at high linear powers in pressurized water conditions. Six fuel elements were irradiated with a ramp power history, achieving a maximum power of 45 kW/m during pre-ramp and of 64 kW/m in the ramp. The maximum discharge burnup was of 216 MWh/kgU. Another three fuel elements with reduced length were irradiated with declining power history. At the beginning of irradiation the fuel elements achieved a maximum linear power of 66 kW/m. The maximum fuel power was about 1.3 times the maximum expected in PHWR. The maximum discharge burnup was 205 MWh/kgU. The elements were destructively examined in the hot cells of INR Pitesti. Temperature-sensitive parameters such as UO{sub 2} grain growth, fission-gas release and sheath deformations were examined. The tests proved the feasibility of irradiating PHWR type fuel elements at linear powers up to 66 kW/m under pressurized water conditions and demonstrated the possibility of more flexible operation of this fuel in power reactors. This paper presents the results of the investigation. (orig.)

Integrative and conjugative elements (ICEs) are self-transmissible chromosomal mobile elements that play significant roles in the dissemination of antimicrobial resistance genes. Identification of the structures and functions of ICEs, particularly those in pathogens, improves understanding of the dissemination of antimicrobial resistance. This study identified new members of the sulfamethoxazole-trimethoprim (SXT)/R391 family of ICEs that could confer multi-drug resistance in the opportunistic pathogen Proteus mirabilis, characterized their genetic structures, and explored their evolutionary connection with other members of this family of ICEs. Three new members of the SXT/R391 family of ICEs were detected in six of 77 P. mirabilis strains isolated in China: ICEPmiChn2 (one strain), ICEPmiChn3 (one strain) and ICEPmiChn4 (three strains). All three new ICEs harbour antimicrobial resistance genes from diverse origins, suggesting their capability in acquiring foreign genes and serving as important carriers for antimicrobial resistance genes. Structural analysis showed that ICEPmiChn3 is a particularly interesting and unique ICE that has lost core genes involved in conjugation, and could not transfer to other cells via conjugation. This finding confirmed the key roles of these missing genes in conjugation. Further phylogenetic analysis suggested that ICEs in geographically close strains are also connected evolutionarily, and ICEPmiChn3 lost its conjugation cassette from a former mobile ICE. The identification and characterization of the three new members of the SXT/R391 family of ICEs in this work leads to suggestions of core ICE genes essential for conjugation, and extends understanding on the structures of ICEs, evolutionary relationships between ICEs, and the antimicrobial resistance mechanisms of P. mirabilis.

Schmidt, Thomas; Nelles, Michael; Scholwin, Frank; Pröter, Jürgen

2014-09-01

A trace element dosing strategy for the anaerobic digestion of wheat stillage was developed in this study. Mesophilic CSTR reactors were operated with the sulfuric substrate wheat stillage in some cases under trace element deficiency. After supplementing trace elements during the start-up, one of the elements of Fe, Ni, Co, Mo, and W were depleted in one digester while still augmenting the other elements to determine minimum requirements for each element. The depletion of Fe and Ni resulted in a rapid accumulation of volatile fatty acids while Co and W seem to have a long-term effect. Based on the results it was possible to reduce the dosing of trace elements, which is positive with reference to economic and environmental aspects. Copyright © 2014 Elsevier Ltd.

Mutations in ash1 and trx enhance P-element-dependent silencing in Drosophila melanogaster.

Science.gov (United States)

McCracken, Allen; Locke, John

2016-08-01

In Drosophila melanogaster, the mini-w(+) transgene in Pci is normally expressed throughout the adult eye; however, when other P or KP elements are present, a variegated-eye phenotype results, indicating random w(+) silencing during development called P-element-dependent silencing (PDS). Mutant Su(var)205 and Su(var)3-7 alleles act as haplo-suppressors/triplo-enhancers of this variegated phenotype, indicating that these heterochromatic modifiers act dose dependently in PDS. Previously, we recovered a spontaneous mutation of P{lacW}ci(Dplac) called P{lacW}ci(DplacE1) (E1) that variegated in the absence of P elements, presumably due to the insertion of an adjacent gypsy element. From a screen for genetic modifiers of E1 variegation, we describe here the isolation of five mutations in ash1 and three in trx that enhance the E1 variegated phenotype in a dose-dependent and cumulative manner. These mutant alleles enhance PDS at E1, and in E1/P{lacW}ci(Dplac), but suppress position effect variegation (PEV) at In(1)w(m)(4). This opposite action is consistent with a model where ASH1 and TRX mark transcriptionally active chromatin domains. If ASH1 or TRX function is lost or reduced, heterochromatin can spread into these domains creating a sink that diverts heterochromatic proteins from other variegating locations, which then may express a suppressed phenotype.

About half of the mammalian genome is composed of retroposons. Long interspersed elements (LINEs) and short interspersed elements (SINEs) are the most abundant repetitive elements and account for about 21% and 13% of the human genome, respectively. SINEs have been detected in all major mammalian lineages, except for the South American order Xenarthra, also termed Edentata (armadillos, anteaters, and sloths). Investigating this order, we discovered a novel high-copy-number family of tRNA derived SINEs in the nine-banded armadillo Dasypus novemcinctus, a species that successfully crossed the Central American land bridge to North America in the Pliocene. A specific computer algorithm was developed, and we detected and extracted 687 specific SINEs from databases. Termed DAS-SINEs, we further divided them into six distinct subfamilies. We extracted tRNA(Ala)-derived monomers, two types of dimers, and three subfamilies of chimeric fusion products of a tRNA(Ala) domain and an approximately 180-nt sequence of thus far unidentified origin. Comparisons of secondary structures of the DAS-SINEs' tRNA domains suggest selective pressure to maintain a tRNA-like D-arm structure in the respective founder RNAs, as shown by compensatory mutations. By analysis of subfamily-specific genetic variability, comparison of the proportion of direct repeats, and analysis of self-integrations as well as key events of dimerization and deletions or insertions, we were able to delineate the evolutionary history of the DAS-SINE subfamilies.

Physical properties of W gravities and W strings

Das, S.R.; Dhar, A.; Rama, S.K.

This paper investigates some basic physical properties of W gravities and W strings, using a free field realization. The authors argue that the configuration space of W gravities have global characteristics in addition to the Euler characteristic. The authors identify one such global quantity to be a monopole charge and show how this charge appears in the exponents. The free energy would then involve a θ parameter. Using a BRST procedure the authors find all the physical states of W 3 and W 4 gravities, and show that physical operators are nonsingular composites of the screening charge operators. (The latter are not physical operators for N ≥ 3.) For W strings we show how the W constraints lead to the emergence of a single (and not many) extra dimension coming from the W-gravity sector. By analyzing the resulting dispersion relations the authors find that both the lower and upper critical dimensions are lowered compared to ordinary two-dimensional gravity. The pure W gravity spectrum reveals an intriguing numerological connection with unitary minimal models coupled to ordinary gravity

Cross-protection in Neisseria meningitidis serogroups Y and W polysaccharides: A comparative conformational analysis.

Kuttel, Michelle M; Timol, Zaheer; Ravenscroft, Neil

2017-06-29

The capsular polysaccharide is the main virulence factor in meningococcus. The capsular polysaccharides for meningococcal serogroups Y and W are almost identical polymers of hexose-sialic acid, suggesting the possibility of cross-protection between group Y and W vaccines. However, early studies indicated that they elicit different levels of cross-protection. Here we explore the conformations of the meningococcal Y and W polysaccharides with molecular dynamics simulations of three repeating unit oligosaccharide strands. We find differences in Y and W antigen conformation: the Y polysaccharide has a single dominant conformation, whereas W exhibits a family of conformations including the Y conformation. This result is supported by our NMR NOESY analysis, which indicates key close contacts for W that are not present in Y. These conformational differences provide an explanation for the different levels of cross-protection measured for the Y and W monovalent vaccines and the high group W responses observed in HibMenCY-TT vaccinees.

To examine the cultural variability in Expressed Emotion (EE) among families of white and ethnic minority adolescents with anorexia nervosa (AN). One-hundred and eighty-nine AN patients and their parents completed the Eating Disorder Examination and the Structured Clinical Family Interview, from which EE ratings were made. No differences were found in the number of white and minority families classified as high EE. White families were higher on warmth (W) and tended to be higher on positive remarks (PR) than minority families. High EE was associated with a longer duration of illness, but was not related to eating disorder pathology. Few differences were found between white and ethnic minority families on the EE dimensions of CC, hostility (H), or EOI. Differences between families on W and PR, however, may have important treatment implications. Copyright © 2010 Wiley Periodicals, Inc.

The corrosion stability of a W-DLC coated surgical AISI 316L stainless steel in Hanks' solution has been evaluated. Particle induced X-ray emission (PIXE) measurements were performed to evaluate the incorporation of potentially bioactive elements from the physiological solution. The film structure was analyzed by X-ray diffractometry and micro-Raman spectroscopy. The wear behavior was assessed using the sphere-on-disc geometry. The in vitro biocompatibility of the W-DLC film was evaluated by cytotoxicity tests. The corrosion resistance of the stainless steel substrate decreased in the presence of the PVD layer. EIS measurements suggest that this behavior was closely related to the corrosion attack through the coating pores. PIXE measurements revealed the presence of Ca and P in the W-DLC film after immersion in Hanks' solution. This result shows that the PIXE technique can be applied to identify and evaluate the incorporation of bioactive elements by W-DLC films. The film showed good wear resistance and biocompatibility.

The Superheavy Elements and Anti-Gravity

Anastasovski, Petar K.

2004-02-01

The essence of any propulsion concept is to overcome gravity. Anti-gravity is a natural means to achieve this. Thus, the technology to pursue anti-gravity, by using superheavy elements, may provide a new propulsion paradigm. The theory of superluminal relativity provides a hypothesis for existence of elements with atomic number up to Z = 145, some of which may possess anti-gravity properties. Analysis results show that curved space-time exists demonstrating both gravitic and anti-gravitic properties not only around nuclei but inside the nuclei as well.

Short interspersed nuclear elements (SINEs) are non-autonomous non-long terminal repeat retrotransposons which are widely distributed in eukaryotic organisms. While SINEs have been intensively studied in animals, only limited information is available about plant SINEs. We analysed 22 SINE families from seven genomes of the Amaranthaceae family and identified 34 806 SINEs, including 19 549 full-length copies. With the focus on sugar beet (Beta vulgaris), we performed a comparative analysis of the diversity, genomic and chromosomal organization and the methylation of SINEs to provide a detailed insight into the evolution and age of Amaranthaceae SINEs. The lengths of consensus sequences of SINEs range from 113 nucleotides (nt) up to 224 nt. The SINEs show dispersed distribution on all chromosomes but were found with higher incidence in subterminal euchromatic chromosome regions. The methylation of SINEs is increased compared with their flanking regions, and the strongest effect is visible for cytosines in the CHH context, indicating an involvement of asymmetric methylation in the silencing of SINEs. © 2015 The Authors The Plant Journal © 2015 John Wiley & Sons Ltd.

Synergistic immune responses induced by endogenous retrovirus and herpesvirus antigens result in increased production of inflammatory cytokines in multiple sclerosis patients

Human endogenous retroviruses (HERV) and herpesviruses are increasingly associated with the pathogenesis of the neurological inflammatory disease multiple sclerosis (MS). Herpesviruses are capable of HERV activation and simultaneous presence of HERV and herpesvirus antigens have a synergistic...... effect on cell-mediated immune responses, which tend to be higher in MS patients in comparison with healthy individuals. Here, we investigate whether these synergistic immune responses are reflected in changes in the production of proinflammatory cytokines. Using enzyme-linked immunosorbent assays...

2002-01-01

This paper presents the results and the methodology used to calibrate the thermal power of the TRIGA MARK I IPR-R1 Reactor in CDTN, Belo Horizonte, Brazil. This calibration was realized during the operation tests carried out to allow the reactor power upgrade from the current 100 kW to 250 kW. The methodology consisted in the measurement of the inlet and outlet temperature and the water flow in the primary cooling loop. The thermal balance together with the thermal losses gave the thermal power. There were made three sequences of tests. The first rising of the thermal power was made with the usual configuration of the core (59 fuel elements). After the changing of the ion chambers position and the control rod and the increase of the number of fuels (63 fuel elements), a new evaluation of the thermal power was accomplished, having been obtained a thermal power of 234 kW, for an indication of 250 kW in the lineal channel. After the return of the core to the initial configuration (59 fuel elements), it took place a new test, getting back the reactor to the power level of 100 kW. (author)

The role of human endogenous retroviruses in brain development and function.

Endogenous retroviral sequences are spread throughout the genome of all humans, and make up about 8% of the genome. Despite their prevalence, the function of human endogenous retroviruses (HERVs) in humans is largely unknown. In this review we focus on the brain, and evaluate studies in animal models that address mechanisms of endogenous retrovirus activation in the brain and central nervous system (CNS). One such study in mice found that TRIM28, a protein critical for mouse early development, regulates transcription and silencing of endogenous retroviruses in neural progenitor cells. Another intriguing finding in human brain cells and mouse models was that endogenous retrovirus HERV-K appears to be protective against neurotoxins. We also report on studies that associate HERVs with human diseases of the brain and CNS. There is little doubt of an association between HERVs and a number of CNS diseases. However, a cause and effect relationship between HERVs and these diseases has not yet been established. © 2016 APMIS. Published by John Wiley & Sons Ltd.

PRACTALL – nowe zalecenia w leczeniu astmy u dzieci

Full Text Available Astma oskrzelowa jest najczęstszą przewlekłą chorobą układu oddechowego występującą u dzieci. Chociaż jej rozpoznawanie w większości przypadków oparte jest na wywiadzie i stosunkowo prostych badaniach dodatkowych, wydaje się, że choroba ta często pozostaje niezdiagnozowana przez lekarzy rodzinnych i pediatrów. Również leczenie astmy – choć stosunkowo proste – pozostawia wiele do życzenia. Taka sytuacja występuje nie tylko w Polsce, podobnie jest na całym świecie. W zależności od kraju lub kontynentu to samo dziecko chore na astmę może zostać poddane leczeniu różnego rodzaju. Dzieje się tak z wielu powodów, między innymi dlatego, że leczeniem astmy na świecie zajmuje się szerokie grono specjalistów, począwszy od lekarzy rodzinnych, przez pediatrów i pulmonologów, a na alergologach skończywszy. Dotychczasowe zalecenia dotyczące diagnostyki i leczenia astmy u dzieci stanowiły zaledwie część dokumentów poświęconych dorosłym pacjentom. Opublikowane niedawno zalecenia PRACTALL dotyczą diagnostyki i leczenia astmy oskrzelowej u dzieci. W niniejszej pracy zawarto omówienie tego ważnego konsensusu pediatrycznego, pierwszego ogólnoświatowego tak obszernego dokumentu poświęconego chorobie, która stanowi ważne wyzwanie dla lekarzy rodzinnych, pediatrów, pulmonologów dziecięcych i alergologów. Konsensus ten omawia i wprowadza do praktyki klinicznej większość najnowszych badań nad astmą oskrzelową i świstami u dzieci. Niektóre zmiany mają charakter nowatorski i przełomowy, gdy chodzi o diagnostykę i leczenie astmy dziecięcej. W poniższym artykule podjęto próbę omówienia najważniejszych elementów zaleceń PRACTALL.

Highly heterogeneous materials comprised of elements with drastically different densities and shock impedances (e.g., Al and W) may provide additional mesoscale fragmentation mechanisms reducing the characteristic fragment size in comparison with solid materials with similar density (e.g., Stainless Steel 304). Explosively driven expanding ring experiments were conducted with Al-W granular composite rings, processed using hot and cold isostatic pressing, with different morphologies (W polyhedral particles or W rods with high aspect ratio and bonded/unbonded Al spherical particles with different sizes). In comparison to homogeneous samples with a similar density, these granular/porous composites generated fragments with a significantly smaller characteristic size. Scanning Electron Microscopy revealed that fragments had a propensity to be composed of clustered Al and W particles. Finite element simulations were conducted to gain an insight into the mesoscale fragmentation mechanisms and the clustering behavior observed in the experiments. Understanding the mesoscale mechanisms of explosively driven pulverization is important for tailoring the size of the fragments through the alteration of mesostructural properties.

Asteroid families, dynamics and astrometry

International Nuclear Information System (INIS)

Williams, J.G.; Gibson, J.

1987-01-01

The proper elements and family assignments for the 1227 Palomar-Leiden Survey asteroids of high quality were tabulated. In addition to the large table, there are also auxiliary tables of Mars crossers and commensurate objects, histograms of the proper element distributions, and a discussion. Probably the most important part of the discussion describes the Mars crossing boundary, how the closest distances of approach to Mars and Jupiter are calculated, and why the observed population of Mars crossers should bombard that planet episodically rather than uniformly. Analytical work was done to derive velocity distributions of family forming events from proper element distributions subject to assumptions which may be appropriate for cratering events. Software was developed for a microcomputer to permit plotting of the proper elements. Three orthogonal views are generated and stereo pairs can be printed when desired. This program was created for the study of asteroid families. The astrometry task is directed toward measuring and reducing positions on faint comets and the minor planets with less common orbits. The observational material is CCD frames taken with the Palomar 1.5 m telescope. Positions of 10 comets and 16 different asteroids were published on the Minor Planet Circulars

Full Text Available Stress patterns in loan verb lexemes in the dialect used by the Old Believers living in the Suwałki-Augustów region The aim of the article is to present the stress pattern phenomenon in loan verb lexemes which function in the Russian dialect of the Old Believers from the Suwałki-Augustów Region. In the last decades, the insular dialect, separated from the general Russian language, has been influenced by the Polish language. Such influence is visible, in particular, in the vocabulary, in the form of loan translations and idiomatic expressions. Stress patterns, along with the root vocabulary and the morphological system, still remains one of the indicators of the Russian essence of the dialect. The native vocabulary of the Old Believers’ dialect maintains Russian accentuation patterns. A similar situation is observed in the case of stress patterns in lexemes borrowed from Polish, which undergo a stress accentuation adaptation; that is, they feature a shift in the place of the stress in relation to the source language. In loan verb morphemes, one can notice the pattern of stress which is not fixed and depends upon the morphological form or, sometimes, the paroxitonic stress, which results from the influence of the Polish language.   Akcentuacja zapożyczonych leksemów czasownikowych w gwarze staroobrzędowców mieszkających w regionie suwalsko-augustowskim Celem artykułu jest zaprezentowanie zjawiska akcentuacji w zapożyczonych leksemach czasownikowych, funkcjonujących w rosyjskiej gwarze staroobrzędowców z regionu suwalsko-augustowskiego. W ciągu ostatnich kilkudziesięciu lat badana gwara wyspowa, odseparowana od rosyjskiego języka ogólnego, podlega znacznemu wpływowi języka polskiego. Wpływ polszczyzny widoczny jest szczególnie w zasobie leksykalnym w postaci zapożyczeń, kalk i w idiomatyce. Akcentuacja obok rdzennego zasobu leksykalnego i systemu morfologicznego nadal pozostaje jednym z wyznaczników rosyjskości gwary

The validity of John Paul II’s concept of education in a family [Aktualność Jana Pawła II koncepcji wychowania w rodzinie

Full Text Available Searching for a concept of education in a family occupies not only theorists of education but also parents and those persons with a lively interest in practical activities directed to helping families. The Holy Father John Paul II presented a Christian perspective of family and education: He treated the family as an inseparable relationship between a woman and a man, directed from one side towards the good of the spouses and from the other towards the transmission of life to children. Education, as understood by John Paul II, is one of the basic aims of a family, it is one of its most important tasks. The process relies on mutual gift of one’s humanity and takes place during interactions between family members. The success of educational process in a family depends on the quality of relationship between parents: whether spouses – parents take trouble to establish and maintain a true community of persons, whether their relationship is based on mutual trust. Parenthood is understood by John Paul II as a gift and as a task, from which follows the basic right, and simultaneously an obligation, to educate children in accordance with one’s beliefs. This task is of such importance that it should not be appropriated by any other entity. Therefore parents are the first and most important educators of their children, responsible for forming in the younger generation the spirit of universal values. The article is to make the reader more familiar with the teaching of John Paul II concerning education in the family and indicate the elements of this teaching which are especially valid for a human being living at the beginning of the XXIth century and searching for the universal concept of education in the family.

Full Text Available Treścią referatu jest problematyka budowlanego procesu inwestycyjnego w pasie drogowym na terenie miast. W aglomeracjach miejskich realizacja zadań związanych z budową, przebudową lub modernizacją ciągów drogowych lub sieci infrastruktury liniowej związana jest z pokonaniem szczególnych utrudnień. Wynika to nie tylko ze specyfiki technologicznej ale również z szeroko pojętej interakcji społecznych. Inwestorzy realizujący zadania w miastach muszą szukać nie tylko innowacyjnych rozwiązań technicznych ale również muszą spełniać, często - „wygórowane” oczekiwania społeczne. W referacie omówione zostaną typowe zagrożenia procesu inwestycyjnego na etapach koncepcji, projektowania, realizacji i eksploatacji - ze szczególnym uwzględnieniem aspektów dotyczących realizacji liniowych robót budowlanych na obszarach objętych warunkami ochrony, wynikającymi z zapisów ustawy o ochronie zabytków[1]. Należy podkreślić, że ochrona ta zgodnie z Art. 4 przedmiotowej Ustawy polega, na podejmowaniu przez organy administracji publicznej działań mających między innymi na celu: zapewnienie warunków prawnych, organizacyjnych i finansowych, umożliwiających trwałe zachowanie zabytków oraz ich zagospodarowanie i utrzymanie. Przekłada się to na obligatoryjny warunek prowadzenia prac konserwatorskich, restauratorskich i oczywiście robót budowlanych za pozwoleniem właściwego konserwatora zabytków i pod jego nadzorem. Realizacja liniowych zadań inwestycyjnych z natury rzeczy odbywa się nie tylko w obszarze wpływu zabytków nieruchomych ale także w bezpośrednim kontakcie z zabytkami archeologicznymi tj. – zabytkami nieruchomymi, będącymi powierzchniową, podziemną lub podwodną pozostałością egzystencji i działalności człowieka, złożoną z nawarstwień kulturowych i znajdujących się w nich wytworów bądź ich śladów.

Full Text Available Operaizm powstał w 1960–1961 roku z inicjatywy Raniero Panzieriego jako nurt radykalnej odnowy teoretycznej marksizmu w walce z obiektywizmem i historyzmem oraz równie radykalnej odnowy strategicznej ruchu robotniczego w walce z dominującym w nim reformizmem. Miał mieć za podstawę materialistyczną lekturę Kapitału „z robotniczego punktu widzenia”. Wkrótce okazało się, że jest głęboko podzielony teoretycznie i politycznie. W 1963 roku w środowisku operaistycznym nastąpił rozłam. Większość skupiona wokół Maria Trontiego oddzieliła się, dokonując antymaterialistycznej rewizji marksizmu i stworzyła metafizykę autonomii robotniczej. Ogromna fala walk robotniczych w latach 1969–1980 przyniosła wyraźne rozstrzygnięcia w fundamentalnych kwestiach spornych, które podzieliły operaistów.

Some refractory trace elements are important target elements for spallation reactions in meteorites. These elements also serve to characterize the investigated meteorites. The elements Ti, Y, Zr, Hf, W and Ta were measured after radiochemical separation in chondrites from China. After acid digestion of the irradiated samples, the group separations were obtained by precipitation reactions. The necessary radiochemical purification of the pure β emitter Y was realized on a Lewatite OC 1026 column. For all the other elements discrete gamma radiation was measured. (orig.)

Full Text Available The demographic changes in Central Europe which started in the 80s of the 20th century began to resemble the changes which were noticed earlier in the countries of Western Europe. Fertility gradually decreased, sometimes even below the simple reproduction rate, the number of marriages dropped and the age when they were made was changing. The model of the family underwent transformations which caused changes in family structures. What followed was a fast change from the so called traditional reproduction to modern reproduction. Demographers are looking for the causes of the above mentioned changes in the influence of economic factors and changes the world view. They also emphasised the need for a family-friendly policy. An important influence on the type of policy of a given country is tradition, the implemented socio-economic policy (e.g., conservative, liberal, the economic situation and public opinion. In a narrower sense it is defined as benefits and services for people with children and single parents. Such an approach means the readiness and constant support in the form of financial transfers made to the families, tax relief for families with children, maternity leaves, the creation and maintenance of institutions which offer child care and family law. In a broad sense, familyfriendly policy covers all areas of social policy which can potentially have an influence on the good of the family (subsidies towards children’s travel costs, education, safety, housing, etc.. The aim of this paper is to describe the changes in the field of demography which took place after 1989 and their effects on families, as well as the policies implemented in the Czech Republic, Poland, Slovakia and Hungary in order to increase reproduction and the number of marriages.

Kit W-sh Mutation Prevents Cancellous Bone Loss during Calcium Deprivation.

2018-01-01

Calcium is essential for normal bone growth and development. Inadequate calcium intake increases the risk of osteoporosis and fractures. Kit ligand/c-Kit signaling plays an important role in regulating bone homeostasis. Mice with c-Kit mutations are osteopenic. The present study aimed to investigate whether impairment of or reduction in c-Kit signaling affects bone turnover during calcium deprivation. Three-week-old male WBB6F1/J-Kit W /Kit W-v /J (W/W v ) mice with c-Kit point mutation, Kit W-sh /HNihrJaeBsmJ (W sh /W sh ) mice with an inversion mutation in the regulatory elements upstream of the c-Kit promoter region, and their wild-type controls (WT) were fed either a normal (0.6% calcium) or a low calcium diet (0.02% calcium) for 3 weeks. μCT analysis indicated that both mutants fed normal calcium diet had significantly decreased cortical thickness and cancellous bone volume compared to WT. The low calcium diet resulted in a comparable reduction in cortical bone volume and cortical thickness in the W/W v and W sh /W sh mice, and their corresponding controls. As expected, the low calcium diet induced cancellous bone loss in the W/W v mice. In contrast, W sh /W sh cancellous bone did not respond to this diet. This c-Kit mutation prevented cancellous bone loss by antagonizing the low calcium diet-induced increase in osteoblast and osteoclast numbers in the W sh /W sh mice. Gene expression profiling showed that calcium deficiency increased Osx, Ocn, Alp, type I collagen, c-Fms, M-CSF, and RANKL/OPG mRNA expression in controls; however, the W sh mutation suppressed these effects. Our findings indicate that although calcium restriction increased bone turnover, leading to osteopenia, the decreased c-Kit expression levels in the W sh /W sh mice prevented the low calcium diet-induced increase in cancellous bone turnover and bone loss but not the cortical bone loss.

A child brought up in foster family [Dziecko wychowywane w rodzinie zastępczej

Full Text Available In a situation when a family does not care about the child and does not fulfil its educational duties to its child, and even where the support given does not result in an improvement of the situation, then the child may be placed in foster care. This leads to the child’s coexistence in two families: the biological one and foster one. In accordance with the law in force in Poland on family support and the foster care system of 20 September 2012, foster care becomes a supplement to parental care-giving and does not replace it. This article is an attempt to show the complexity of the issues concerning the upbringing of a child in two families. Particular attention is paid to the difficult situation of the child, who periodically, by the court’s decision is sent to foster care and functions in a new unrelated family, while maintaining contact with their biological parents, with whom they share a legal bond. This situation raises a number of difficulties experienced by the child – dilemmas and problems with identification and belonging to the foster or biological family. The temporary nature of foster care, its subsidiary character, causes that nowadays the goal of foster families is not to establish ties with the child similar to those resulting from a parent-like attitude but to support, help in the care and upbringing of the child. The article also highlights the resulting threats to the proper functioning of the child

In the second run of the LHC, which started in April 2015, an accurate understanding of Standard Model processes is more crucial than ever. Processes including electroweak gauge bosons serve as standard candles for SM measurements, and equally constitute important background for BSM searches. We here present the NLO QCD virtual contributions to W+W- + jet in an analytic format obtained through unitarity methods and show results for the full process using an implementation into the Monte Carlo event generator MCFM. Phenomenologically, we investigate total as well as differential cross sections for the LHC with 14 TeV center-of-mass energy, as well as a future 100 TeV proton-proton machine. In the format presented here, the one-loop virtual contributions also serve as important ingredients in the calculation of W+W- pair production at NNLO.

Full Text Available Familial adenomatous polyposis (FAP is a rare syndrome characterized by the presence of hundreds to thousands of colorectal adenomas and is responsible for less than 1% of all colorectal cancers. The syndrome is also characterized by extra-colorectal features including amongst others upper gastrointestinal tract polyps and desmoid tumors. The syndrome is inherited by an autosomal dominant gene, the adenomatous polyposis coli (APC gene. We present the physical history, clinical presentation, diagnosis and treatment of a patient with a novel germline APC mutation, the W421X mutation, which resulted in FAP presenting with about a hundred colorectal polyps, gastric hyperplastic polyps and multiple aggressive intra-abdominal and extra-abdominal desmoid tumors.

Full Text Available The oral and nasopharyngeal streptococci are a major part of the normal microbiota in humans. Most human associated streptococci are considered commensals however a small number of them are pathogenic, causing a wide range of diseases including oral infections such as dental caries and periodontitis and diseases at other body sites including sinusitis and endocarditis, and in the case of Streptococcus pneumoniae, meningitis. Both phenotypic and sequence based studies have shown that the human associated streptococci from the mouth and nasopharynx harbour a large number of antibiotic resistance genes and these are often located on mobile genetic elements known as conjugative transposons or integrative and conjugative elements of the Tn916 / Tn1545 family. These mobile genetic elements are responsible for the spread of the resistance genes between streptococci and also between streptococci and other bacteria. In this review we describe the resistances conferred by, and the genetic variations between the many different Tn916-like elements found in recent studies of oral and nasopharyngeal streptococci and show that Tn916-like elements are important mediators of antibiotic resistance genes within this genus. We will also discuss the role of the oral environment and how this is conducive to the transfer of these elements and discuss the contribution of both transformation and conjugation on the transfer and evolution of these elements in different streptococci.

CP violating observables in e$^{-}$e$^{+}$ --> W$^{-}$W$^{+}$

We consider various integrated lepton charge-energy asymmetries and azimuthal asymmetries as tests of CP violation in the process $e^-e^+ \\to W^-W^+$. These asymmetries are sensitive to different linear combinations of the CP violating form factors in the three gauge boson $W^-W^+$ production vertex, and can distinguish dispersive and absorptive parts of the form factors. It makes use of purely hadronic and purely leptonic modes of $W$'s decays as well as the mixed modes. The techniques of using the kinematics of jets or missing momentum to construct CP--odd observables are also employed. These CP violating observables are illustrated in the generalized Left-Right Model and the Charged Higgs Model.

A study of W/sup +/W/sup -/ events accompanied by hard photon radiation, E/sub gamma />2.5 GeV, produced in e^{+}e^{-} collisions at LEP is presented. Events consistent with being two on- shell W-bosons and an isolated photon are selected from 681 pb/sup -1 / of data recorded at 180 GeV< square root s<209 GeV. From the sample of 187 selected W/sup +/W/sup -/ gamma candidates with photon energies greater than 2.5 GeV, the W/sup +/W/sup -/ gamma cross- section is determined at five values of square root s. The results are consistent with the standard model expectation. Averaging over all energies, the ratio of the observed cross-section to the standard model expectation is R(data/SM)=0.99+or-0.09+or-0.04, where the errors represent the statistical and systematic uncertainties respectively. These data provide constraints on the related O( alpha ) systematic uncertainties on the measurement of the W-boson mass at LEP. Finally, the data are used to derive 95% confidence level upper limits on possible anomalo...

We show that the Zamolodchikov's and Polyakov-Bershadsky nonlinear algebras W 3 and W (2) 3 can be embedded as subalgebras into some linear algebras with finite set of currents. Using these linear algebras we find new field realizations of W (2) 3 and W 3 which could be a starting point for constructing new versions of W-string theories. We also reveal a number of hidden relationships between W 3 and W (2) 3 . We conjecture that similar linear algebras can exist for other W-algebra as well. (author). 10 refs

Two Home Countries in the Polish Language Press for Jewish Children in the Second Polish Republic In the interwar period in Poland the big Polish-language Jewish journals (Chwila, Nowy Dziennik and Nasz Przegląd published supplements for children. Two of them (Chwilka and Dzienniczek dla Dzieci i Młodzieży [Diary for children and young people] were typical magazines for children. The third, the Mały Przegląd [Little review], led initially by Janusz Korczak, became the tribune of its youngest readers. Its content was composed of letters, reports and interviews by young correspondents. All these magazines were directed to children of the accultured Jews, readers of Polish-language Zionist press. It would seem, therefore, that their educational ideals should be similar. How were the patriotic values shown to the Jewish children from the acculturated Zionist families, familiar with Polish culture better than average Jewish children, but raised in cult of Palestine and the return to Eretz? What should be told to the children, if they were to be educated as good patriots? And patriots of what country? How to explain Palestinian patriotism to children who have never seen their country, lived in Poland and spoke Polish? And at the same time – how to explain the Polish patriotism to children who live in a country with a constantly growing anti-Semitism, of which they are only the marginalized, second-class citizens.

The role of retrotransposons in gene family expansions: insights from the mouse Abp gene family.

Science.gov (United States)

Janoušek, Václav; Karn, Robert C; Laukaitis, Christina M

2013-05-29

Retrotransposons have been suggested to provide a substrate for non-allelic homologous recombination (NAHR) and thereby promote gene family expansion. Their precise role, however, is controversial. Here we ask whether retrotransposons contributed to the recent expansions of the Androgen-binding protein (Abp) gene families that occurred independently in the mouse and rat genomes. Using dot plot analysis, we found that the most recent duplication in the Abp region of the mouse genome is flanked by L1Md_T elements. Analysis of the sequence of these elements revealed breakpoints that are the relicts of the recombination that caused the duplication, confirming that the duplication arose as a result of NAHR using L1 elements as substrates. L1 and ERVII retrotransposons are considerably denser in the Abp regions than in one Mb flanking regions, while other repeat types are depleted in the Abp regions compared to flanking regions. L1 retrotransposons preferentially accumulated in the Abp gene regions after lineage separation and roughly followed the pattern of Abp gene expansion. By contrast, the proportion of shared vs. lineage-specific ERVII repeats in the Abp region resembles the rest of the genome. We confirmed the role of L1 repeats in Abp gene duplication with the identification of recombinant L1Md_T elements at the edges of the most recent mouse Abp gene duplication. High densities of L1 and ERVII repeats were found in the Abp gene region with abrupt transitions at the region boundaries, suggesting that their higher densities are tightly associated with Abp gene duplication. We observed that the major accumulation of L1 elements occurred after the split of the mouse and rat lineages and that there is a striking overlap between the timing of L1 accumulation and expansion of the Abp gene family in the mouse genome. Establishing a link between the accumulation of L1 elements and the expansion of the Abp gene family and identification of an NAHR-related breakpoint in

Fuel element reactivity worth in different rings of the IPR-R1 TRIGA reactor

Energy Technology Data Exchange (ETDEWEB)

Gomes do Prado Souza, Rose Mary

2008-10-29

The thermal power of the IPR-R1 TRIGA Reactor will be upgraded from 100 kW to 250 kW. Starting core: loaded with 59 aluminum cladded fuel elements; 1.34 $ excess reactivity; and 100 kW power. It is planned to go 2.5 times the power licensed, i.e., 250 kW. This forces to enlarge the reactivity level. Nuclear reactors must have sufficient excess reactivity to compensate the negative reactivity feedback effects caused by: the fuel temperature, fuel burnup, fission poisoning production, and to allow full power operation for predetermined period of time. To provide information for the calculation of the new core arrangement, the reactivity worth of some fuel elements in the core were measured as well as the determination of the core reactivity increase in the substitution of the original fuels, cladded with aluminium, for new ones, cladded with stainless steel. The reactivity worth of fuel element was measured from the difference in critical position of the control rods, calibrated by the positive period method, before and after the fuel element was withdrawn from the core. The magnitude of reactivity increase was determined when withdrawing the original Al-clad fuel (a little burned up) and the graphite elements, and inserting a fresh Al-clad fuel element, one by one. Experimental results indicated that to obtain enough reactivity excess to increase the rector power the addition of 4 new fuel elements in the core would be sufficient: - Substitution of 4 Al-clad fuel elements in ring C for fresh stainless steel clad fuel elements; - increase the reactivity {approx_equal} 4 x 6.5 = 26 cents; - The removed 4 Al-clad F. E. (a little burned up) put in the core periphery, ring F, replacing graphite elements; - add < 4 x 39 156 cents (39 cents was measured with a fresh F.E.). Neutron source was changed from position F7 to F8. Control and Safety rods were moved from ring D to C in order to increase their reactivity worth. Regulating rod was kept at the same position, F16.

Uniwersytet Kazimierza Wielkiego w Bydgoszczy       Streszczenie Kreowanie odpowiednich nawyków wolnoczasowych jest bardzo ważnym aspektem w dzisiejszych czasach. Należy wciąż uświadamiać społeczeństwo, że aktywność fizyczna stanowi niezbędny element zachowania dobrostanu psychicznego i fizycznego człowieka. Wiele osób nadal nie rozumie, że regularna aktywność ruchowa przyczynia się do zmniejszenia ryzyka wystąpienia chorób cywilizacyjnych, na które umiera większość społeczeństwa. Dlatego ważne są badania sprawdzające jak spędzają czas wolny osoby w różnym wieku oraz czy i jakie formy rekreacji ruchowej podejmują, jakie mają podejście do aktywności fizycznej, czy są świadomi, że w ich otoczeniu są organizowane zajęcia sprzyjające zwiększeniu sprawności fizycznej oraz czy i jakie różnice występują między poszczególnymi grupami społecznymi. Badania przeprowadzono, w styczniu 2015 roku, na Uniwersytecie Kazimierza Wielkiego w Bydgoszczy. Badania przeprowadzono na studentach I, II oraz II roku administracji oraz Turystyki i Rekreacji. Zgromadzony materiał badawczy to 102  ankiety, po 17 na każdym roczniku i kierunku. W badaniu wzięło udział 74 kobiety oraz 28 mężczyzn w wieku od 19 do 25 lat. Analizując wyniki badań można wysunąć wniosek, że występują małe różnice w postrzeganiu aktywności fizycznej studentów administracji oraz turystyki i rekreacji. Studenci TiR częściej wybierają aktywność ruchową. Jak widać studenci administracji mają nieco inne priorytety lub być może wiedza na temat rekreacji ruchowej nie jest im tak często i skutecznie przekazywana jak studentom TiR.   Słowa kluczowe: czas wolny, aktywność fizyczna, rekreacja ruchowa, studenci.     Abstract Creating the appropriate lot of habits is a very important aspect nowadays. You should still realize a society that physical activity is an essential element in maintaining a mental or physical man. Many people

Zlewnia Potoku Służewieckiego jest zlokalizowana w południowej części Warszawy. Największe zagrożenie powodziowe występuje na odcinku Potoku Służewieckiego od km 0+000 do 3+875. Przepustowość koryta Potoku na tym odcinku kształtuje się na poziomie przepływu maksymalnego o prawdopodobieństwie 50%. Największe wartości przepływów w Potoku Służewieckim prognozowano w przekroju obliczeniowym numer V (km 4+267: Q50% = 13,863, Q10% = 23,019, Q2% = 28,825 i Q1% = 30,500 m3·s-1. Jedną z przyczyn występowania zagrożenia powodziowego w dolnym biegu Potoku Służewieckiego jest dopływ dużej ilości wód opadowych Rowem Wolica. Wartości przepływów w górnym odcinku Rowu Wolica (w przekroju VI zawierały się w granicach od 8,005 do 12,402 m3·s-1, w zależności od prawdopodobieństwa wystąpienia opadu obliczeniowego. W celu określenia możliwości redukcji przepływów w Rowie Wolica, przeprowadzono obliczenia w których uwzględniono zastosowanie kryzy na odcinku ujściowym kolektora do kanału otwartego. Zastosowanie kryzy w kolektorze pozwoli zredukować przepływy o prawdopodobieństwach 50, 10 i 2% odpowiednio o 61,0; 46,0 i 36,6%. Zastosowanie kryzy o stałej średnicy ϕ1,08 m, ustalonej dla przepływu o prawdopodobieństwie 2%, spowoduje znacznie mniejszą redukcję przepływów maksymalnych o prawdopodobieństwach 50 i 10%.

2015-02-15

The geographical traceability of virgin olive oil can be controlled by chemical species that are linked to the production area. Trace elements are among these species. The hypothesis is that the transfer of elements from the soil to the oil is subjected to minor variations and therefore this chemical information can be used for geographical traceability. In order to confirm this hypothesis, the trace elements of virgin olive oils from south-western Spain were analysed, and the same elements were determined in the corresponding olive-pomaces and soils. The differences in the concentration were studied according to cultivars and locations. Results show some coincidences in the selection of elements in soils (W, Fe, Na), olive-pomace (W, Fe, Na, Mg, Mn, Ca, Ba, Li) and olive oils (W, Fe, Mg, Mn, Ca, Ba, Li, Bi), which supports their utility in traceability. In the case of olive oils, 93% of the samples were correctly classified in their geographical origins (96% for Beas, 77% for Gibraleón, 91% for Niebla, and 100% for Sanlúcar de Guadiana).

Setting-out of objects on the exploitation field of the mine, both in surface mining and in the underground mines, is determined by the specified setting-out accuracy of reference points, which are best to define spatial position of the object projected. For the purpose of achieving of the specified accuracy, it is necessary to perform a priori accuracy assessment of parameters, which are to be used when performing setting-out. Based on the a priori accuracy assessment, verification of the quality of geometrical setting- -out elements specified in the layout; definition of the accuracy for setting-out of geometrical elements; selection of setting-out method; selection at the type and class of instruments and tools that need to be applied in order to achieve predefined accuracy. The paper displays the accuracy assessment of geometrical elements for setting-out of the main haul gallery, haul downcast and helical conveying downcasts in shape of an inclined helix in horizontal plane, using the example of the underground bauxite mine »Kosturi«, Srebrenica. Wytyczanie obiektów na polu wydobywczym w kopalniach, zarówno podziemnych jak i odkrywkowych, zależy w dużej mierze od określonej dokładności wytyczania punktów referencyjnych, przy pomocy których określane jest następnie położenie przestrzenne pozostałych obiektów. W celu uzyskania założonej dokładności, należy przeprowadzić wstępną analizę dokładności oszacowania parametrów które następnie wykorzystane będą w procesie wytyczania. W oparciu o wyniki wstępnej analizy dokładności dokonuje się weryfikacji jakości geometrycznego wytyczenia elementów zaznaczonych na szkicu, uwzględniając te wyniki dobrać należy odpowiednią metodę wytyczania i rodzaj oraz klasę wykorzystywanych narzędzi i instrumentów, tak by osiągnąć założony poziom dokładności.

Chociaż w historiografii dominuje akcentowanie cech warownych tych miejsc, to jednak nie możemy mieć wątpliwości, że krzyżacki zamek tworzył wybraną przestrzeń, która miała ułatwić zakonnikom, zarówno kapłanom jak i braciom rycerzom, spełnianie obowiązków zakonnych oraz służyć organizacji życia wspólnotowego. W konsekwencji krzyżacki dom zakonny miał pomóc każdemu z jego mieszkańców w osiągnięciu zbawienia. ...

Detection and location of leaking TRIGA fuel elements

International Nuclear Information System (INIS)

Bouchey, G.D.; Gage, S.J.

1970-01-01

Several TRIGA facilities have experienced difficulty resulting from cladding failures of aluminum clad TRIGA fuel elements. Recently, at the University of Texas at Austin reactor facility, fission product releases were observed during 250 kW operation and were attributed to a leaking fuel element. A rather extensive testing program has been undertaken to locate the faulty element. The used sniffer device is described, which provides a quick, easily constructed, and extremely sensitive means of locating leaking fuel elements. The difficulty at The University of Texas was compounded by extremely low levels and the sporadic nature of the releases. However, in the more typical situation, in which a faulty element consistently releases relatively large quantities of fission gas, such a device should locate the leak with little difficulty

A reconnaissance view of tungsten reservoirs in some crustal and mantle rocks: Implications for interpreting W isotopic compositions and crust-mantle W cycling

their significance for crust-mantle HFSE and siderophile element budgets - to be tested in future studies. The significant concentration of W, as well as Nb and Ta hosted in rutile and titanite has interesting implications for the budget of W during crust-mantle recycling. Crust-mantle recycling models invoking the recycling of rutile-bearing eclogites to satisfy the mantle Nb/Ta ratio carry the penalty that the very high W/U and W/Th ratios of these rocks results in a concomitant large deviation from the primitive mantle-like ratios estimated for bulk continental crust. Similarly, data from the single amphibolite sample investigated in this study are inconsistent with models implicating the partial melting of amphibolite-bearing subducted slabs as a major process for formation of continental crust in the Earth's early history. Either the current widely accepted estimates for bulk continental crust W/U and W/Th ratios are in error, or partial melting or other processes lowers the W/U or W/Th of melt residues during their return to the mantle. The present small dataset cannot properly evaluate this, requiring further investigation. Finally, the lithospheric mantle has the potential to store substantial amounts of W, for example via infiltration by W-rich melts/fluids, and thus may act as a source for W mineralization in the crust.

Precision measurement and interpretation of inclusive W"+, W"- and Z/γ* production cross sections with the ATLAS detector

2017-01-01

High-precision measurements by the ATLAS Collaboration are presented of inclusive W"+ → l"+ν, W"- → l"- anti ν and Z/γ* → ll (l = e,μ) Drell-Yan production cross sections at the LHC. The data were collected in proton-proton collisions at √(s) = 7 TeV with an integrated luminosity of 4.6 fb"-"1. Differential W"+ and W"- cross sections are measured in a lepton pseudorapidity range vertical stroke η_l vertical stroke < 2.5. Differential Z/γ* cross sections are measured as a function of the absolute dilepton rapidity, for vertical stroke y_l_l vertical stroke < 3.6, for three intervals of dilepton mass, m_l_l, extending from 46 to 150 GeV. The integrated and differential electron- and muon-channel cross sections are combined and compared to theoretical predictions using recent sets of parton distribution functions. The data, together with the final inclusive e"±p scattering cross-section data from H1 and ZEUS, are interpreted in a next-to-next-to-leading-order QCD analysis, and a new set of parton distribution functions, ATLAS-epWZ16, is obtained. The ratio of strange-to-light sea-quark densities in the proton is determined more accurately than in previous determinations based on collider data only, and is established to be close to unity in the sensitivity range of the data. A new measurement of the CKM matrix element vertical stroke V_c_s vertical stroke is also provided. (orig.)

The e+e- --> W+W- cross section is measured in a data sample collected by ALEPH at a mean centre--of--mass energy of 172.09 GEV, corresponding to an integrated luminosity of 10.65 pb-1. Cross sections are given for the three topologies, fully leptonic, semi-leptonic and hadronic of a W-pair decay. Under the assumption that no other decay modes are present, the W-pair cross section is measured to be 11.7 +- 1.2 (stat.) +- 0.3 (syst.) pb. The existence of the triple gauge boson vertex of the Standard Model is clearly preferred by the data. The decay branching ratio of the W boson into hadrons is measured to be B(W --> hadrons) = 67.7 +- 3.1 (stat.) +- 0.7 (syst.)%, allowing a determination of the CKM matrix element |Vcs|= 0.98 +- 0.14 (stat.) +- 0.03 (syst.).

The e+e--->W+W- cross section is measured in a data sample collected by ALEPH at a mean centre-of-mass energy of 172.09 GeV, corresponding to an integrated luminosity of 10.65 pb-1. Cross sections are given for the three topologies, fully leptonic, semi-leptonic and hadronic of a W-pair decay. Under the assumption that no other decay modes are present, the W-pair cross section is measured to be 11.7+/-1.2(stat.)+/-0.3(syst.) pb. The existence of the triple gauge boson vertex of the Standard Model is clearly preferred by the data. The decay branching ratio of the W boson into hadrons is measured to be B(W-->hadrons)=67.7+/-3.1(stat.)+/-0.7(syst.) %, allowing a determination of the CKM matrix element Vcs=0.98+/-0.14(stat.)+/-0.03(syst.).

Hydrophilic Surface Modification of PDMS Microchannel for O/W and W/O/W Emulsions

2015-09-01

Full Text Available A surface modification method for bonded polydimethylsiloxane (PDMS microchannels is presented herein. Polymerization of acrylic acid was performed on the surface of a microchannel using an inline atmospheric pressure dielectric barrier microplasma technique. The surface treatment changes the wettability of the microchannel from hydrophobic to hydrophilic. This is a challenging task due to the fast hydrophobic recovery of the PDMS surface after modification. This modification allows the formation of highly monodisperse oil-in-water (O/W droplets. The generation of water-in-oil-in-water (W/O/W double emulsions was successfully achieved by connecting in series a hydrophobic microchip with a modified hydrophilic microchip. An original channel blocking technique to pattern the surface wettability of a specific section of a microchip using a viscous liquid comprising a mixture of honey and glycerol, is also presented for generating W/O/W emulsions on a single chip.

A one-parameter family of hamiltonian structures for the KP hierarchy and a continuous deformation of the nonlinear WKP algebra

International Nuclear Information System (INIS)

Figueroa-O'Farrill, J.M.; Mas, J.; Ramos, E.

1993-01-01

The KP hierarchy is hamiltonian relative to a one-parameter family of Poisson structures obtained from a generalized Adler map in the space of formal pseudodifferential symbols with noninteger powers. The resulting W-algebra is a one-parameter deformation of W KP admitting a central extension for generic values of the parameter, reducing naturally to W n for special values of the parameter, and contracting to the centrally extended W 1+∞ , W ∞ and further truncations. In the classical limit, all algebras in the one-parameter family are equivalent and isomorphic to W KP . The reduction induced by setting the spin-one field to zero yields a one-parameter deformation of W ∞ which contracts to a new nonlinear algebra of the W ∞ -type. (orig.)

The rotational elements of Mars and its satellites

The International Astronomical Union (IAU) defines planet and satellite coordinate systems relative to their axis of rotation and the angle about that axis. The rotational elements of the bodies are the right ascension and declination of the rotation axis in the International Celestial Reference Frame and the rotation angle, W, measured easterly along the body's equator. The IAU specifies the location of the body's prime meridian by providing a value for W at epoch J2000. We provide new trigonometric series representations of the rotational elements of Mars and its satellites, Phobos and Deimos. The series for Mars are from a least squares fit to the rotation model used to orient the Martian gravity field. The series for the satellites are from a least squares fit to rotation models developed in accordance with IAU conventions from recent ephemerides.

Detection of the YORP effect for small asteroids in the Karin family

Science.gov (United States)

Nesvorny, David; Carruba, Valerio; Vokrouhlicky, David

2016-10-01

The Karin family formed by a collisional breakup of a ~40-km parent asteroid only 5.75 Myr ago. The young age can be demonstrated by numerically integrating the orbits of Karin family members backward in time and showing the convergence of orbital elements. Previous work has pointed out that the convergence is not ideal if the backward integration only accounts for the gravitational perturbations from the Solar System planets. It improves when the thermal radiation force known as the Yarkovsky effect is accounted for. This method can be used to estimate the spin obliquities of Karin family members. Here we show that the obliquity distribution of diameter D=1-2 km asteroids in the Karin family is bimodal, as expected if the YORP effect acted to move obliquities toward extreme values (0 or 180 deg). The measured magnitude of the effect is consistent with the standard YORP model. Specifically, the strength of the YORP effect is inferred to be roughly 70% of the nominal YORP strength obtained for a collection of random Gaussian spheroids. The surface thermal conductivity is found to be 0.07-0.2 W/m/K (thermal inertia 300-500 in the SI units). These results are consistent with surfaces composed of rough and rocky regolith. The obliquity values predicted here for 480 members of the Karin cluster can be validated by the lightcurve inversion method. In broader context, the bimodal distribution of obliquities in the Karin cluster can be thought as an initial stage of dynamical evolution that later leads to a characteristically bi-lobed distribution of family members in the semimajor axis (e.g., Eos, Merxia or Erigone families).

The Superheavy Elements and Anti-Gravity

International Nuclear Information System (INIS)

Anastasovski, Petar K.

2004-01-01

The essence of any propulsion concept is to overcome gravity. Anti-gravity is a natural means to achieve this. Thus, the technology to pursue anti-gravity, by using superheavy elements, may provide a new propulsion paradigm. The theory of superluminal relativity provides a hypothesis for existence of elements with atomic number up to Z = 145, some of which may possess anti-gravity properties. Analysis results show that curved space-time exists demonstrating both gravitic and anti-gravitic properties not only around nuclei but inside the nuclei as well. Two groups of elements (Z < 64 and 63 < Z <145) exist that demonstrate these capabilities. The nuclei of the first group of elements have the masses with only the property of gravity. The nuclei of the elements of the second group have the masses with both properties: gravity and anti-gravity in two different ranges of curved space-time around the nuclei.. The hypothetical element with Z = 145 is the unique among all elements whose nucleus has only anti-gravity property. It is proposed that this element be named Hawking, in honour of Stephen W. Hawking

The morphological stasis of coelacanths has long suggested a slow evolutionary rate. General genomic stasis might also imply a decrease of transposable elements activity. To evaluate the potential activity of transposable elements (TEs) in "living fossil" species, transcriptomic data of Latimeria chalumnae and its Indonesian congener Latimeria menadoensis were compared through the RNA-sequencing mapping procedures in three different organs (liver, testis, and muscle). The analysis of coelacanth transcriptomes highlights a significant percentage of transcribed TEs in both species. Major contributors are LINE retrotransposons, especially from the CR1 family. Furthermore, some particular elements such as a LF-SINE and a LINE2 sequences seem to be more expressed than other elements. The amount of TEs expressed in testis suggests possible transposition burst in incoming generations. Moreover, significant amount of TEs in liver and muscle transcriptomes were also observed. Analyses of elements displaying marked organ-specific expression gave us the opportunity to highlight exaptation cases, that is, the recruitment of TEs as new cellular genes, but also to identify a new Latimeria-specific family of Short Interspersed Nuclear Elements called CoeG-SINEs. Overall, transcriptome results do not seem to be in line with a slow-evolving genome with poor TE activity. © 2013 Wiley Periodicals, Inc.

We propose possible signatures of `exogamous' combinations between partons in the different W+ and W- hadron showers in e+e- -> W+W- events with purely hadronic final states. Within the space-time model for hadronic shower development that we have proposed previously, we find a possible difference of about 10 % between the mean hadronic multiplicity in such purely hadronic final states and twice the hadronic multiplicity in events in which one W decays hadronically and the other leptonically,...

Physical states and scaling properties of W gravities and W strings

International Nuclear Information System (INIS)

Das, S.R.; Dhar, A.; Rama, S.K.

1992-01-01

In this paper the authors discuss some physical aspects of W gravities and W strings. The authors identify global characteristics in W gravities (in addition to the usual Euler characteristic) and show how the dependence of the partition function on the various chemical potentials involves these quantities. The authors find the operators which create physical states in W 3 and W 4 gravities and discuss their relationship with screening operators. W strings are discussed in the framework of a natural way of coupling matter to W gravity, and the issues of extra dimensions and critical dimensions are clarified. The authors find a remarkable relationship between pure W gravities and ordinary gravity coupled to c < 1 unitary minimal models

Data collected at LEP at centre-of-mass energies \\sqrt(s) = 189 - 209 GeV are used to study correlations of the spin of W bosons using e+e- -> W+W- -> lnqq~ events. Spin correlations are favoured by data, and found to agree with the Standard Model predictions. In addition, correlations between the W-boson decay planes are studied in e+e- -> W+W- -> lnqq~ and e+e- -> W+W- -> qq~qq~ events. Decay-plane correlations, consistent with zero and with the Standard Model predictions, are measured.

In this work direct laser writing of diffractive optical elements (DOE) by photodeposition (PD) of amorphous selenium (a-Se) from colloid solutions has been investigated. We used a computer controlled laser scanner for patterning thin film micro-profiles creating thus planar optical elements by direct beam writing on surfaces immersed in a liquid phase PD cell. The laser employed was an argon ion laser at 488 nm wavelength, with powers up to 55 mW, for writing typically 25-250 μm wide lines of 200 nm thickness at rates of about 150 μm/s. Various elements made of photodeposited thin films on polymethyl-methacrylate (PMMA) substrates were produced for prototyping microlenses, linear grating arrays, cylindrical and circular profiled DOE patterns
