    Sprog er normalt underkastet et ikonisk princip, ifølge hvilket kvantorers indbyrdes scopeforhold bestemmes af deres rækkeølge i overfladestrukturen. Hvordan kan det så være, at Tous les Français ne boivent pas du vin betyder, at ikke alle franskmænd drikker vin, og ikke, at 'alle ikke', dvs....... 'ingen', drikker vin? Artiklen foreslår en modulær forklaring på dette fænomen, der ofte har været bemærket, men hidtil ikke er blevet forklaret. Analysen, der inddrager modulerne for scopestruktur, logisk værdi, fokalisering og polyfoni viser sig i stand til også at forudse tilsyneladende modeksempler......, og yder som uventet sideeffekt et bidrag til forklaringen på anvendelsen af de i stedet for du i sætninger som Paul ne boit pas de vin....

    Vin Santo is the typical dessert wine produced in Tuscany, in particular, and in other areas of central and northern Italy, as well as on the Greek island of Santorini. It remains one of the most important "meditation wines", whose glamour starts with its ancient and mysterious origin. Italy is the country with the World's greatest tradition for sweet wine production. In this contest most of the steps in the Vin Santo making process are still linked to old local traditions. This chapter provides an overview of the different styles of Vin Santo produced in Italy together with its marketing. The main factors affecting grapes drying, alcoholic fermentation, maturation in barrels, are also described. So far there have been few scientific studies that have focused on Vin Santo. However, the increasing demand registered in the last few years for this kind of wine, is now greatly stimulating the research aimed to better manage its peculiar production process.

    2008-02-01

    Vulvar pathology is located at the border between dermatology and gynaecology. The gynaecologist is concerned by VIN (vulvar intraepithelial neoplasia) lesions as patients meet them for that problem. He makes distinction with dermatologic lesions so as to refer proper patients to dermatologists. A recent classification of VIN has a major interest. One individualizes two kinds of precancerous lesions. The first one is lichen sclerosis with dermatologic treatment by dermocorticoids and the other aetiology is HPV infection with frequent association with cervical localisation. Gynaecologists are more familiar with this second aetiology. Thus, they have to (i) check for VIN, (ii) know their appearance and how the diagnosis can be made by biopsy, (iii) precise the aetiology, (iv) appreciate the severity of the disease, (v) discuss which treatment is indicated: destruction or surgery.

    Investigation of the structural, electronic and magnetic properties of full-Heusler Co2VIn as well as half-Heusler CoVIn Cobalt based Heusler compounds using density functional theory (DFT) leads to the general conclusion that Co2VIn and CoVIn are half-metallic materials with a gap at the Fermi level in the minority states and majority states respectively. A Hubbard-like Coulomb correlation term U has been included in the DFT (DFT+U) for the computation of the electronic and magnetic properties of the compounds. The structural properties have been calculated for the paramagnetic and ferromagnetic phases, and both Co2VIn and CoVIn are found to be stable in the ferromagnetic phase. The calculated magnetic moments are 2 μB and 0.9 μB per formula unit for Co2VIn and CoVIn respectively.

  8. Vinča bowls with protoma

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available Bowls with protoma represent one of several tens of types of Vinča vessels made of baked clay which have been published as finds excavated at Vinča sites for more than a century. We are dealing here with bowls of a markedly conical profile, with angled and slightly rounded walls and with a flat or slightly annular bottom. In most cases these bowls are not decorated, with the exception of the rare finds decorated by fluting, engraving and polishing. Their most significant peculiarity is the presence of four or eight protoma on the rim, facing the inside of the vessel. Taking into consideration all stylistic-typological characteristics, it is possible to divide them into two coherent categories of finds. The first consists of bowls with four oppositely placed protoma. Within this group it is possible to single out two subtypes, bowls with all four as anthropomorphic (Pl. I/6, 7; Pl. III/34 or all four as zoomorphic representations (Pl. I/5, 8, 9; Pl. III/33, 36. Bowls with eight protoma have actually got four pairs of oppositely placed representations. It was possible to discern two subtypes based on the objects that were completely preserved. The first subtype includes a bowl from the so-called Vinča ritual set, with two pairs of zoomorphic and two pairs of anthropomorphic protoma, both oppositely placed (Pl. I/3. The second subtype includes a bowl from house 1/2010 from Stubline with four identical, paired, totally stylised and schematised representations, whose identification is impossible (Fig. 1; Pl. I/1. Taking into consideration the metric and technological data, the thesis that seems most possible is that the bowls with protoma served for the consumption of or the storing/displaying of the content during some quite specific activities. Bowls with protoma appear in almost all regions of the central Balkans populated by Vinča culture communities and we do not note them in the areas of the neighbouring Late Neolithic communities.

    Vulvar intraepithelial neoplasia (VIN) represents a current diagnostic and therapeutic challenge. The present retrospective study is an institutional experience on the diagnosis and management of VIN. One hundred and thirteen women with VIN were reviewed and analyzed. Diagnosis was established by colposcopically directed biopsies whereas treatment was performed by either a surgical or a laser CO2 approach. The mean age of all VIN patients was 47.4 years. The most common symptom was pruritus (60.1%). The majority of the lesions were multifocal (N = 64, 56.6%) and located in the non-hairy part of the vulva (87.6%). VIN management consisted of laser CO2 treatment in 51 patients (45.1%), surgical treatment in 37 (32.7%) whereas 25 VIN, cases were managed by conventional medical treatment. The risk of disease relapse was not associated with VIN grade (p = 0.35) nor with the treatment modality used (p = 0.42). The risk of disease relapse was significantly higher for multifocal lesions (p VIN. Although the benefits of treatment are obvious there seems to be no guarantee that invasion will not occur.

    Usual vulvar intraepithelial neoplasia (uVIN) is the most common VIN type, generally related to a human papillomavirus (HPV) infection, predominantly type 16. The incidence of uVIN has been increasing over the last decades, and a bimodal peak is observed at the age of 40–44 and over 55 years. Almost 40% of patients with uVIN have a past, concomitant or future HPV-associated lesion of the lower genital tract. HPV-related malignancies are associated with a persistent HPV infection. The host immune response is of crucial importance in determining clearance or persistence of both HPV infections and HPV-related VIN. About 60% of the patients present with symptoms. Clinical features of uVIN vary in site, number, size, shape, colour, and thickness of lesions. Multicentric disease is often present. Most uVIN lesions are positive at immunohistochemistry to p16ink4a and p14arf, but negative to p53. Irrespective of surgical treatment used, uVIN recurrence rates are high. Positive margins do not predict the development of invasive disease and the need to re-excide the tissue around the scare remains to be demonstrated. Therefore, considering the low progression rate of uVIN and psycosexual sequelae, treatments should be as conservative as possible. Medical treatments available are mainly based on immunotherapy to induce normalisation of immune cell count in uVIN. None are approved by the food and drug administration (FDA) for the treatment of uVIN. If medical treatment is performed, adequate biopsies are required to reduce the risk of unrecognised invasive disease. Some studies suggest that failure to respond to immunotherapy might be related to a local immunosuppressive microenvironment, but knowledge of the uVIN microenvironment is limited. Moreover, our knowledge of the potential mechanisms involved in the escape of HPV-induced lesions from the immune system has many gaps. HPV vaccines have been demonstrated to be effective in preventing uVIN, with 94.9% efficacy in the

    The incidence of vulvar intraepithelial neoplasia (VIN) has increased in the last decades. The therapy of VIN is the in toto resection. Still some patients develop VIN recurrence. The aim of this retrospective study is the identification of risk factors for VIN recurrence. 68 Patients with VIN III has been examined in an univariate and multivariate analysis for the following parameters (follow-up: median 27 months): age, HPV, HIV, multicentricity, resection margins (1-4 mm, 5-9 mm, > or = 10 mm). In the univariate analysis positive HPV and HIV status correlated with VIN recurrence. Also resection margins VIN recurrence. Multivariate analysis demonstrated that HPV, HIV and resection margins VIN therapy must be the total resection with a negative resection margin of > or = 5 mm. HPV- and/or HIV-positive patients have a significantly higher risk for VIN recurrence and need therefore an intensive follow up.

    Vulvar intraepithelial neoplasia (VIN) is classified into 2 clinicopathologic subtypes, classic, related to human papillomavirus (HPV) infection and affecting relatively young women, and simplex (differentiated), negative for HPV and affecting elderly women. Histologically, classic VIN may be basaloid and characterized by a replacement of the whole epidermis by a homogeneous population of small, "undifferentiated" keratinocytes, which are diffusely positive for p16(INK4a) and negative for p53. Simplex VIN is characterized by atypia of the basal layer with high degree of cellular differentiation and shows negative staining for p16(INK4a) and frequent positivity for p53. Simplex VIN is frequently associated with squamous cell hyperplasia and lichen sclerosus. From a series of 110 invasive squamous cell carcinomas of the vulva negative for HPV by highly sensitive polymerase chain reaction, 51 had VIN lesions located at least 1 cm away from the tumor. In 4 (7.8%) cases, the VIN had basaloid histologic features. All cases showed obvious architectural disorganization with a homogeneous population of basaloid, undifferentiated keratinocytes with scanty cytoplasm replacing the whole epidermis. Immunohistochemically, all cases were negative for p16(INK4a) and strongly positive for p53 with suprabasilar extension of positive cells. All patients were postmenopausal (median age 61.0 y; range, 45-76). Squamous cell hyperplasia was identified in 1 case and lichen sclerosus in 1 case. The invasive squamous cell carcinoma was of keratinizing type in 3 cases and basaloid in 1 case. In conclusion, simplex, HPV-negative VIN may occasionally have basaloid morphology. Immunostaining for p16(INK4a) and p53 protein may be helpful in the identification of these lesions and the differential diagnosis with classic, HPV-positive basaloid VIN.

    Full Text Available Avec l’expansion coloniale européenne et le développement de nouvelles routes commerciales transcontinentales et maritimes au XVIe siècle, le vin conquiert de nouveaux espaces géographiques et sociaux. Avant le contact européen, le vin est un produit culturel inconnu au Canada. La présence de vignes canadiennes qui croissent à l’état sauvage suscite beaucoup d’espoirs et semble confirmer que le Nouveau Monde est une terre d’abondance. Les lambrusques locales n’atteignent cependant pas les critères de qualité auxquels les Français s’attendent : en dépit des soins, elles ne produisent qu’un vin médiocre. L’acclimatation de vignes françaises est tentée, dans l’espoir de parvenir à implanter ce symbole civilisateur en terre de colonisation, mais l’expérience fonctionne mal en raison du climat rigoureux. Puisque les espoirs vinicoles coloniaux sont voués à l’échec, l’importation s’avère nécessaire. En définitive, la consommation de vin permet d’affirmer et de confirmer son identité française.With the colonial adventure and the development of new commercial and maritime routes in the 16th century, wine gains over new geographic and social areas. Before European contact, wine is unknown as a cultural product. Some Canadian vineyards grow naturally: they raise up many hopes and seem to confirm that the New World is a wealthy world. But the local plants can’t satisfy French standards: despite all cares, they produce a bad, second-rate wine. The acclimatization of French vine is also disappointing because of icy Canadian winters. Since colonial vine-growing is bound to fail, importation becomes necessary. Finally, wine is an essential beverage in the colonial adventure: drinking wine permits to state and confirm a French identity.

    The purpose of the present study is to investigate the trends in incidence of both usual (u) and differentiated (d) vulvar intraepithelial neoplasia (VIN) separately, their malignant potential and the relation with other HPV related anogenital lesions in the Netherlands during a 14-year-period. The incidences of both types of VIN and vulvar SCC were retrieved from the Nationwide Netherlands Database of Histo- and Cytopathology. Population data were retrieved from the Database of Statistics Netherlands. In the study period, the incidence of uVIN and dVIN increased, while the incidence of vulvar SCC remained stable. The overall percentage of uVIN patients that were later diagnosed with vulvar SCC was 5.7%, which was significantly lower than the percentage for dVIN patients (32.8%). In addition to this 5.6-fold increased conversion rate, the time of progression from dVIN to SCC development was significantly shorter than that of uVIN (p=0.005). Percentage of uVIN patients that were later diagnosed with SCC significantly increased with age (p=0.005), whereas the time to SCC significantly shortened with age (p=0.05). Forty-one percent of uVIN patients had a past, concomitant or future HPV-associated lesion of the lower genital tract, which is in contrast to the 3% for dVIN patients. An increase in diagnoses of both uVIN and dVIN has not led to an increase in vulvar SCC incidence. The malignant potential of dVIN is higher than that for uVIN. For uVIN the malignant potential increases with age.

    The pathogenesis of vulvar squamous cell carcinoma follows 1 of 2 distinct pathways. A precursor lesion in the human papilloma virus-independent pathway, differentiated vulvar intraepithelial neoplasia (dVIN), was only recently characterized in detail and is infrequently diagnosed without an associated component of invasive carcinoma. Aberrant p53 immunostaining is frequently seen in dVIN, and in approximately 25% to 30% of cases it manifests as a complete loss or a p53-null pattern. The abrupt transition between p53 loss and basal p53 expression in lesional versus nonlesional epithelium allows clear demarcation between neoplastic and non-neoplastic epithelium. For this study, 14 specimens from 10 patients were identified from the pathology archives of 2 teaching hospitals on the basis of: (1) a diagnosis of dVIN, with or without invasive carcinoma; and (2) p53-null immunostaining pattern in lesional cells. Ten specimens had associated invasive carcinoma. All sections from each specimen that showed the specimen resection margin were stained for p53 and reviewed together with all hematoxylin and eosin sections. Detailed morphologic assessment of the p53-null epithelium was made and compared with the adjacent benign squamous epithelium. The status of the resection margins based on the original pathologic assessment was compared with that assessed with p53 immunohistochemistry. One specimen showed p53 loss in the invasive carcinoma but patchy basal positivity in the region originally diagnosed as dVIN, supporting interpretation as a benign hyperplastic focus, rather than dVIN. In the remaining 13 specimens the areas originally diagnosed as dVIN, as well as the associated invasive carcinoma (if present), were p53-null. In 8 of these specimens, on the basis of the presence of p53-null immunostaining and subtle morphologic abnormalities, dVIN was more extensive than originally recognized.

    Vulvar cancer is a rare disease and its screening is depending on the quality and the relevance of our clinical examination. Incidence of vulvar cancer and especially precancerous lesions, vulvar intraepithelial neoplasias (VIN), increased during these last years. The new terminology of vulvar intraepithelial neoplasia will help us to identify high risk groups which could develop a cancer: usual and differentiated VIN. An early diagnosis is essential to propose an adequate treatment. Management is a major point according to the rising incidence of these lesions in younger women. Until we can observe a benefit from the vaccination against human papillomavirus, we must increase the quality of screening by a careful examination of the vulva.

    Vulvar intraepithelial neoplasia (VIN) is a premalignant disorder caused by human papillomaviruses. Basic knowledge about the molecular pathogenesis of VIN is sparse. Therefore, we have analyzed the gene expression profile of 9 VIN samples in comparison to 10 control samples by using genome wide Affymetrix Human U133A plus2 GeneChips. Results were validated by quantitative real-time RT-PCR analysis and immunostaining of a few representative genes (TACSTD1, CCNE2, AR and ESR1). Significance analysis of microarrays (SAM) showed that 1,497 genes were differentially expressed in VIN compared to controls. By analyzing the biological processes affected by the observed differences, we found that VIN appears to be a highly proliferative disease; many cyclins (CCNA, CCNB and CCNE) and almost all prereplication complex proteins are upregulated. Thereby, VIN does not seem to depend for its proliferation on paracrine or endocrine signals. Many receptors (for example ESR1 and AR) and ligands are downregulated. Furthermore, although VIN is not an invasive disease, the inhibition of expression of a marked number of cell-cell adhesion molecules seems to indicate development towards invasion. Upon reviewing apoptosis and angiogenesis, it was observed that these processes have not become significantly disregulated in VIN. although VIN is still a premalignant disease, it already displays several hallmarks of cancer.

    Vulvar intraepithelial neoplasia (VIN) is a premalignant lesion of the vulva. The incidence of VIN is increasing. The surgery is currently the gold standard therapy for VIN, but Imiquimod could be a completion to surgery. The aim of this study is to compare the overall complete response, the recurrence rate and the risk factors for recurrence among two groups of patients: women with high grade VIN underwent surgery and patients treated with surgery plus Imiquimod. 80 patients with histologically diagnosed VIN 2/3 were enrolled in this prospective study. Our patients were divided into two groups: 40 women underwent surgery (A) and 40 patients were treated with surgery plus Imiquimod (B). All women had a 5-year follow-up. Recurrence rate and complete response were evaluated. The following patients' characteristics were analyzed: smoke, multifocal disease, multicentric disease, degree of the lesion. In the group A recurrence rate was 44.8%, in the group B it was 48.4%. In both groups the presence of multifocal lesions (p = 0.02) and VIN 3 (p = 0.006) before treatment was associated with a higher risk of recurrence. This study found that surgery remains the principal approach for VIN with regard to relapse and complete response since the treatment with Imiquimod associated with surgery didn't show a lower recurrence rate. Although the surgical treatments remain the best therapeutic option for VIN with regard to recurrence and overall complete response, the combined therapy seems to be an interesting modality, but further studies are needed.

    Vulvar intraepithelial neoplasia (VIN) is a premalignant disease of the vulvar squamous epithelium. Standard treatment for VIN lesions is surgical excision. Alternative therapeutic options for conservative treatment have been sought by patients to prevent disfigurement and to preserve sexual function. We present such a patient in whom topical imiquimod was used with a successful outcome. Imiquimod is effective in the treatment of VIN, as well as convenient, self-administered, and generally well tolerated.

    Full Text Available Recent work at Vinča-Belo Brdo has combined a total of more than 200 radiocarbon dates with an array of other information to construct much more precise narratives for the structural history of the site and the cultural materials recovered from it. In this paper, we present the results of a recent attempt to construct formal models for the chronology of the wider Vinča potscape, so that we can place our now detailed understanding of changes at Belo Brdo within their contemporary contexts. We present our methodology for assessing the potential of the existing corpus of more than 600 radiocarbon dates for refining the chronology of the five phases of Vinča ceramics proposed by Milojčić across their spatial ranges, including a total of 490 of them in a series of Bayesian chronological models. Then we outline our main results for the development of Vinča pottery. Finally, we discuss some of the major implications for our understanding of the source, character and tempo of material change.

    Full Text Available La viticulture biologique française est une filière dynamique. Si certaines évolutions de la demande de bio sont similaires à celles observées pour le vin conventionnel (rosé, Bag-in-box, …, d'autres comme la demande de vins sans sulfites ou de vins « vegan » interpellent plus spécifiquement ce segment. La filière des vins bio se trouve à la fois devoir respecter la règlementation viticole et celle de la production en bio, que ce soit par le cahier des charges de production de la matière première « raisin » que de sa transformation en vin. Elle doit satisfaire des consommateurs exigeants et fédérer des producteurs passionnés parfois jusqu'à l'excès. Face à cette forte dynamique de développement soutenue par une demande qui contourne partiellement les circuits classiques de distribution, la filière française des vins bio (France Vins Bio a souhaité mener un exercice de prospective conduit par FranceAgriMer et Montpellier SupAgro. La présente communication va présenter, après un rappel des grands principes et de la méthode de prospective utilisée, les thématiques explorées, les principales hypothèses combinées et l'essentiel des scénarios sur lesquels elles débouchent.

    Usual type VIN is a premalignant disorder caused by persistent HPV infection. High prevalence of VIN in immuno-suppressed women suggests that a good innate and adaptive immune response is important for defense against HPV. Here, we explored expression levels of chemokines and related these to the presence or absence of immuno-competent cells (dendritic and T-cells) in affected (HPV-positive VIN) and non-affected (HPV-negative) vulvar tissues from the same patients. Combining microarray data with quantitative real-time RT-PCR, it was observed that several important chemokines were differentially expressed between VIN and control samples (up-regulation of IL8, CXCL10, CCL20 and CCL22 and down-regulation of CXCL12, CCL21 and CCL14). Furthermore, an increased number of mature dendritic cells (CD208+) seemed to be bottled up in the dermis, and although a T-cell response (increased CD4+ and CD8+ cells) was observed in VIN, a much larger response is required to clear the infection. In summary, it seems that most mature dendritic cells do not receive the proper chemokine signal for migration and will stay in the dermis, not able to present viral antigen to naive T-cells in the lymph node. Consequently the adaptive immune response diminishes, resulting in a persistent HPV infection with increased risk for neoplasia.

    Vulval intraepithelial neoplasia (VIN) is thought to be the premalignant phase of human papillomavirus (HPV)-associated vulval squamous cell carcinoma (VSCC). Various molecular events have been suggested as markers for progression from VIN to VSCC, but loss of heterozygosity (LOH) in vulval neoplasia has rarely been studied in this context. We performed LOH analysis by polymerase chain reaction (PCR) amplification of polymorphic microsatellite markers at 6 chromosomal loci (17p13-p53, 9p21-p16, 3p25, 4q21, 5p14 and 11p15). The presence of HPV was assessed using consensus PCR primers and DNA sequencing. To examine any association between LOH and the presence of invasive disease, we analyzed 43 cases of lone VIN III, 42 cases of lone VSCC and 21 cases of VIN with concurrent VSCC. HPV DNA was detected in 95% of lone VIN III samples and 71% of lone VSCC samples. Fractional regional allelic loss (FRL) in VIN associated with VSCC was higher than in lone VIN (mean FRL 0.43 vs. 0.21, p VIN, reflected by LOH, may increase the risk of invasion. In addition, molecular events differ in HPV-positive and -negative VSCC and 3p25 may be the site of a tumor suppressor gene involved in HPV-independent vulval carcinogenesis.

    2009-01-01

    Full Text Available The following paper will discuss the problems of Eneolithic settlements of Baden and Kostolac culture at Vinča near Belgrade. Eneolithic horizons from Vinča site were scarcely published owing to the fact that both Baden and Kostolac layers are not well stratified because of heavy medieval devastations. In spite of all post-depositional destructions Eneolithic settlements at Vinča show enormous significance for understanding the life of the period, both on the micro and macro-regional scale. At the same time, this work is a sort of an insight into the results of ongoing analysis of material culture and socio-economic patterns of Eneolithic period settlements in Belgrade and its vicinity.

    To evaluate demographic and clinical characteristics associated with the development of vulvar intraepithelial neoplasia (VIN 2/3), and factors associated with recurrence. A retrospective chart review of 303 patients with VIN 2/3 evaluated at a single institution between 1993 and 2011 was performed. Medical records were reviewed for demographic information, risk factors, treatment type, pathologic diagnosis, and recurrence/outcome information. Median age at diagnosis was 47 years (range 14-87). 40% of patients reported current tobacco use and 26% reported previous use. Primary treatment included excision (n=176, 59%), laser ablation (n=40, 13%), imiquimod (n=22, 7.4%), excision with laser (n=24, 8.1%), excision with imiquimod (n=10, 3.4%), and laser with imiquimod (n=3, 1.0%). 92 patients (62.6%) were noted to have positive margins, which was associated with larger tumor size (p=0.004). 87 patients (28.7%) developed recurrent disease, which was associated with smoking (pVIN 2/3 diagnosis. This large cohort of women with VIN 2/3 further delineates the demographic and clinical factors associated with VIN 2/3. High rates of recurrence were noted and found to be associated with smoking, larger lesion size, and positive margins. While higher rates of recurrence were found among those treated with laser ablation, it was not inferior with respect to RFS when used alone, but the use of laser with excision was associated with decreased RFS. Our findings provide hypothesis-generating material for further research in the management of VIN2/3. Copyright © 2012 Elsevier Inc. All rights reserved.

    2003-01-01

    Although high-grade vulvar intraepithelial neoplasia (VIN III) is a clinically significant lesion, it can be overlooked because of nonspecific clinical findings and the fact that its cytomorphologic features mimic those of mild cervical intraepithelial neoplasia (CIN I). To determine if there are cytomorphologic features on Papanicolaou tests that can reliably distinguish between VIN III and CIN I. Papanicolaou tests diagnosed as CIN I from patients with biopsy-proven CIN I were compared with Papanicolaou tests diagnosed as CIN I from patients with biopsy-proven VIN III but with no biopsy-proven CIN I. None of the cytomorphologic features evaluated could reliably distinguish CIN I from VIN III. Since the Papanicolaou test cannot be used to distinguish between CIN I and VIN III, the clinician must pay careful attention to the clinical and colposcopic findings. Further research evaluating the use of ancillary studies, such as human papillomavirus typing, may be useful.

    To determine the recurrence rates in patients who underwent different surgical treatments for vulvar intraepithelial neoplasia (VIN) 2 and 3. Data on every patient who underwent surgical treatment for VIN 2 or 3 between January 1994 and December 2002 by a single gynecologic oncologist were retrospectively reviewed. The recurrence rates for 3 different surgical therapies were analyzed using Fischer's exact test. Thirty-three patients, who had a median age of 46 years (range, 31-80), were identified. The preoperative biopsy demonstrated VIN 2 or 3 in 9.1% and 90.9% of the patients, respectively. The following primary surgical procedures were employed: 16 patients (48.4%) underwent excisional partial vulvectomy with CO2 laser ablation of the margins, 10 patients (30.3%) had CO2 laser ablation alone, 6 patients (18.2%) had an excisional partial vulvectomy, and 1 patient (3.0%) was. treated with the ultrasonic surgical aspirator. No patient had invasive disease. Recurrent disease was seen in 7 patients (70.0%) treated by laser alone, 3 patients (50.0%) who had an excisional partial vulvectomy and 1 patient (6.25%) who underwent a combined laser and excisional partial vulvectomy (p = 0.0016). The results of this small study suggest that laser and excisional partial vulvectomy for the treatment of VIN 2 and 3 may be associated with a lower recurrence rate than either modality alone. A larger study will be needed to confirm these results.

    To assess whether pre-treatment HPV types are associated with recurrence of high-grade vulvar intraepithelial neoplasia (VIN2+). Data of consecutive patients with pretreatment HPV DNA test undergoing treatment for VIN2+ were retrospectively collected. Risk factors promoting the risk of VIN2+ persistence and recurrence were analyzed using Kaplan-Meier and Cox hazard proportional models. 64 patients had pretreatment vulvar-vaginal HPV DNA test. Two were excluded due to the presence of synchronous vulvar cancer, thus leaving 62 patients for the final analysis. HPV16, HPV18, HPV31 and HPV33 were the most common HPV genotype detected, occurring in 15 (24.2%), 4 (6.5%), 8 (12.9%) and 5 (8.0%) patients, respectively. HPV was not detected in 19 (30.6%) patients. During a mean (SD) follow up of 56.7 (±26.7) months, 10 (16.1%) patients had VIN2+ persistence/recurrence. Mean (SD) lesion-free interval was 51.7 (±31.4) months. Via multivariate analysis, pretreatment infection from HPV31 (HR:46.7(95%CI:4.21,518.4); p=0.02) and HPV33 (HR:77.0(95%CI:6.73,881.9); pVIN2+ persistence/recurrence. Additionally, we observed that patients undergoing surgical excision followed by LASER ablation experienced a trend towards lower recurrence rate than patients undergoing other surgical or medical treatments (HR:0.20(95%CI:0.03,1.09); p=0.05). Two (3.2%) patients developed progression to vulvar cancer. Owing to the inherent biases of the retrospective study design and the small sample size, our data have to be corroborated by larger and prospective studies. HPV31 and HPV33 have a potential role in predicting VIN2+ persistence/recurrence. These findings will be paramount, owing to the implementation of new immunization programs.

    Full Text Available This paper aims to reconstruct the marital residence patterns in late Neolithic communities in the central Balkans. The average size of the habitation site was used as a correlate of patrilocality or matrilocality. A study of the habitation sites of the Vinča culture shows that judgments about marital residence patterns vary between sites and their phases. There are, however, certain indications that patrilocality may be considered the more probable pattern for most of the sites.

    Angiogenesis plays an important role both in progression of solid tumors and in metastasizing. An invasive growth of a neoplasm is mainly connected with appearing of blood vessels within a tumor. Inhibition of angiogenesis in solid neoplasms may deter both tumor growth and metastases. New treatment strategies based on suppressing of angiogenesis and selective damaging of neoplastic blood vessels may prove to be as efficient as those based on direct destruction of neoplastic cells. One of important angiogenic factors is vascular endothelial growth factor (VEGF), which is produced by neoplastic cells and shows high promitotic activity almost entirely for endothelial cells (paracrine activity). We decided to investigate VEGF expression in precancerous lesions as well as in squamous cancers of vulva. Our material included 31 cases of vulvar squamous cancer, 28 cases of VIN (vulvar intraepithelial neoplasia) III, 10 VIN II cases and 12 VIN I cases. A diagnosis was established according to WHO criteria on the ground of post-operative histopathological examination complemented with proliferation index estimated by the use of MIB-1 antibody. Immunohistochemical examinations were performed on paraffin-embedded material, using MIB-1 antibody (Immunotech), VEGF antibody (Santa Cruz), Goat serum Normal (DAKO), DAKO StreptAB-Complex/HRP Duet, Mouse/Rabbit DAKO DAB Chromogen Tablets, TBS (Sigma). Positive cytoplasmic expression of anti-VEGF polyclonal antibody (diffuse and/or focal and of various intensity) was observed in almost all samples from precancerous and cancerous lesions. The expression was especially strong and diffuse in all cancer cases; in cases of VIN it was mainly focal and weak.

In the first section of this work we present the comprehensive report about the investigations carried out so far. The geomagnetic prospection undertaken from 2006 to 2008 covered an area of 32,400 square meters and the obtained results indicate the existence of around 100 houses built in rows around the rather large open areas as well as the trenches surrounding the settlement. The investigations of the house 1/2008 dating from the Vinča culture D-2 period yielded in addition to the data concerning its interior organization also a unique find of the group of 46 figurines with 11 models of miniature tools. In the second section of this work we discuss the prospects, which future investigations of this site and its environment could provide concerning the study of the social organization in the very end of the Vinča culture.

    Full Text Available The goal of this paper is to determine whether there are reasons to believe that inventories from the Late Neolithic Vinča culture houses do not represent systemic assemblages and to offer an interpretation of household assemblage variation. Pottery inventories from Vinča culture houses were compared to the ethnographically recorded range of variation in household inventory size. The discard equation was used to make projections of the accumulated assemblages from house assemblages for comparison with empirically observed accumulated assemblages. It is concluded that in general there is no reason to reject the assumption that Vinča household inventories reflect systemic assemblages. Moreover, the patterns of inventory variability can be meaningfully interpreted in social terms. [Projekat Ministarstva nauke Republike Srbije, br. 177008

    Vulvar intraepithelial neoplasia (VIN) is a premalingnant condition. For long time, surgery was considered the first-line therapy in the treatment of high grade VIN. Imiquimod was recently introduced as an alternative to surgery. To compare the overall complete response, the recurrence rate and the risk factors for relapse among patients with VIN 2/3 treated with Imiquimod or surgical excision. Eighty women who had histological diagnosis of VIN 2 and VIN 3 were enrolled in this prospective study. Patients immunocompromised, with recurrent VIN, with well differentiated type VIN or VIN 1 and women treated more than once were excluded from the study. Patients were divided into two groups: group A was treated with Imiquimod, group B underwent surgical excision. Patients' characteristics analyzed were: age, smoking, degree of the primary lesion, state of margins, multifocal disease. We have evaluated the recurrence rate, the relapse rate, and the overall complete response, considering as recurrence the onset of a lesion after an initial complete response to Imiquimod and/or after the surgical treatment and as relapse all patients who had a recurrence plus those with medical treatment failure. Multifocal lesions (p = 0.03) and VIN 3 (p = 0.002) were associated with a higher risk of relapse. The recurrence rate was higher in the group B (p = 0.009), but the relapse rate was higher in the group A (p = 0.04). The overall complete response was better in the group B (p = 0.04). Although the advent of new medical options can decrease the morbidity associated with invasive surgical procedures, surgical treatments remain the best treatment modality for VIN with regard to relapse and overall complete response.

    Becker, G.; Kardaun, O.

    2007-01-01

    Predictions of density profiles in current tokamaks and ITER require a validated scaling relation for vin/D where vin is the anomalous inward drift velocity and D is the anomalous diffusion coefficient. Transport analysis is necessary for determining the anomalous particle pinch from measured density profiles and for separating the impact of particle sources. A set of discharges in ASDEX Upgrade, DIII-D, JET and ASDEX is analysed using a special version of the 1.5-D BALDUR transport code. Profiles of ρsvin/D with ρs the effective separatrix radius, five other dimensionless parameters and many further quantities in the confinement zone are compiled, resulting in the dataset VIND1.dat, which covers a wide parameter range. Weighted multiple regression is applied to the ASDEX Upgrade subset which leads to a two-term scaling \\rho _sv_in ({x'}) /D ({x'}) =0.0432 [ { ({L_{T_{\\rme}} ({ \\bar {x}'}) / \\rho _s}) ^{-2.58}+7.13 \\, U_L^{1.55} \

Because of temperature variations in the cellars, this velum sinks partially into the wine and a deposit of dead yeasts cells accumulates in the bottom of the barrels, favouring the formation of new velum. Growth and autolysis occur simultaneously. This study investigated the evolution of macromolecules released by yeasts during the ageing of "Vin jaune" in a model system closely simulating winemaking. It was observed that the release of macromolecules during the formation of the velums by living yeasts was low but greatly increased when the velums fell and yeast viability decreased. The release of macromolecules was then due to the autolysis of dead cells. Analysis of macromolecules during ageing revealed that they contained 73.3-78.5% neutral sugars and 6-7% proteins according to the ageing stage. Their amino acid composition did not change during ageing. A high content of serine and threonine commonly involved in O-glycosidic linkages present in yeast mannoproteins was observed. Throughout ageing, the mannose and glucose contents of macromolecules increased but the ratio of polymeric mannose to glucose decreased. Size exclusion chromatography showed that mannoproteins released in wine were partially hydrolysed by yeast beta-1,3-glucanases freed in wine.

    Models help operators and decision makers explore and compare different management and policy alternatives, better allocate scarce resources, and predict the future behavior of existing or proposed water systems. Hydroeconomic models are useful tools to increase benefits or decrease costs of managing water. Bringing hydrology and economics together, these models provide a framework for different disciplines that share similar objectives. This work proposes a new model to evaluate operation and adaptation strategies under existing and future hydrologic conditions for California's interconnected water system. This model combines the network structure of CALVIN, a statewide optimization model for California's water infrastructure, along with an open source solver written in the Python programming language. With the flexibilities of the model, reservoir operations, including water supply and hydropower, groundwater pumping, and the Delta water operations and requirements can now be better represented. Given time series of hydrologic inputs to the model, typical outputs include urban, agricultural and wildlife refuge water deliveries and shortage costs, conjunctive use of surface and groundwater systems, and insights into policy and management decisions, such as capacity expansion and groundwater management policies. Water market operations also represented in the model, allocating water from lower-valued users to higher-valued users. PyVIN serves as a cross-platform, extensible model to evaluate systemwide water operations. PyVIN separates data from the model structure, enabling model to be easily applied to other parts of the world where water is a scarce resource.

    The majority of vulvar intraepithelial neoplasia (VIN) is high-grade and is related to high-risk human papillomavirus (HRHPV) (most commonly HPV16). It is considered to be the precursor of HRHPV-related vulvar squamous cell carcinoma. Vulvar condyloma acuminatum is low-risk HPV (LRHPV)-related (most commonly types 6 and 11) and has virtually no risk of neoplastic progression. While infection with multiple LR- and HRHPV types has been reported for cervical squamous intraepithelial lesions, coexisting vulvar condyloma and adjacent high-grade VIN have not been well characterized. Eleven cases of concurrent condyloma acuminatum and adjacent flat high-grade VIN and three cases of high-grade VIN with prominent condylomatous architecture were analyzed using immunohistochemical (IHC) analysis of p16 expression, in situ hybridization (ISH) for HPV detection (HPV6/11, HPV16, HPV 18, and HPV WS [types 6,11,16,18,31,33,35,45,51,52] probes), and HPV typing by PCR-based method (in select cases). All patients had underlying immunosuppressive conditions (human immunodeficiency virus infection or post-transplant therapy). Among the 11 cases of concurrent high-grade VIN and condyloma, the lesions were directly adjacent to one another in 5 cases (with 2 of these demonstrating an intimate admixture of lesions), and in 6 cases were found in separate tissue sections from the same specimen. Diffuse/strong p16 expression was seen in all high-grade VIN lesions, whereas patchy/weak staining was found in all condylomata. All condylomata contained HPV 6 or 11 as detected by ISH. All of the accompanying high-grade VIN lesions had HRHPV detected. Ten contained HPV 16 (9 by ISH, 1 by PCR), with the remaining case containing multiple HPV types by PCR. All condylomatous high-grade VIN lesions demonstrated diffuse/strong p16 expression and had evidence of HRHPV (one with HPV 16 by ISH, one with HPV 18 by ISH, and one with multiple HPV types by PCR), with no detection of HPV 6 or 11 by ISH.

    2010-01-01

    Full Text Available During excavation of the Vinča-Belo Brdo site a significant number of decorated items made from clay, stone, bone, and seashells or snail shells have been collected over the years. Amongst the decorated objects which could be classified as jewellery the majority are bracelets, pendants, and beads made from Spondylus and Glycymeris shells, as well as beads made from Dentalium shells. The appearance of these beads and the question of their origin have not yet been specifically considered within studies of prehistoric cultures in the central Balkans. Furthermore, they have rarely been illustrated and mentioned in archaeological site inventories, which we presume has not been because of their poor representation, but rather because of their being unfamiliar. The aim of this work is therefore to: a systematize data about Dentalium beads from all phases of excavation of the Belo Brdo site in Vinča; b to show the importance of this kind of jewellery in the study of resources around the Vinča settlement; and c to indicate the wider chronological perspective and the significance of studying Dentalium beads within the prehistory of the central Balkans. Dentalium is a carnivorous Scaphopoda sea mollusc, uncommon and insufficiently studied. Representatives of this class of Scaphopoda have been found on Serbian territory in the Badenian sediments, deposited fifteen million years ago. Badenian sediments were discovered around Loznica, Belgrade, Aranđelovac, Golubac, Zaječar, and Negotin. The region of Belgrade and the surrounding area had been covered by a warm, shallow sea of normal salination. On the territory of Belgrade, offsprings of the Badenian sediments, rich in fossils, have been discovered in the city centre (Tašmajdan, Kalemegdan, as well as in many surrounding places (Rakovica, Kaluđerica, Leštani, and Jajinci (fig. 2.

    The current study investigated the clinical benefit, the impact on biochemical and objective response and tolerability of weekly docetaxel with vinorelbine (VIN-DOX) in symptomatic patients with hormone refractory prostate cancer (HRPC). Patients were treated with docetaxel 25 mg/m2 and vinorelbine 20 mg/m2, intravenously for 6 consecutive weeks followed by a 2 week rest repeatedly until disease progression. Clinical benefit evaluations, based on Karnofsky performance status (KPS) and pain measure, were assessed weekly during therapy. A clinical benefit response was defined as a sustained (> or =4 weeks) improvements in one of these parameters. Changes in prostate-specific antigen (PSA) levels, tumoral response and toxicity also were evaluated. 19 men (median age 68 years), were treated. Overall, 42% of patients achieved a KPS significant change and positive pain response; 47% achieved a 50% or greater reduction in PSA. The objective response rate was observed in 2 of 9 patients with measurable disease (22%). The most important toxicity was neutropenia (Grade 3 = 32%). The combination of weekly VIN-DOX appears to be feasible. VIN-DOX was found to be associated with improvement in clinical benefit response and biochemical response and well tolerated as first line treatment in HRPC.

    To assess the effectiveness of the 2015 version of the French Évin Law that was implemented in 1991 with the objective of protecting young people from alcohol advertising. Data were obtained from survey questions measuring exposure and receptivity to alcohol advertisements that were introduced for the first time in the 2015 European School Survey Project on Alcohol and Other Drugs (ESPAD). A representative sample of 6642 10th-12th grade students (mean age 17.3 years) were interviewed in 198 schools in France by a self-administered questionnaire. Information was collected on alcohol advertising exposure in different media (outside billboards, internet, etc.) and receptivity to recent advertisements (attractiveness, incentive to drink, etc.). The majority of students declared that they had been exposed at least once a month to alcohol advertisements in supermarkets (73.2%), in movies (66.1%), magazines and newspapers (59.1%), on billboards in streets (54.5%), and on the internet (54.1%). Concerning the last recalled advertisements, 27.8% remembered the beverage type, 18.2% the brand, 13% felt like having a drink after having seen the advertisement and 19.6% found the advertisement attractive (boys ranked significantly higher than girls for all these indicators; P-value exposure to alcohol advertising in France. © 2016 Society for the Study of Addiction.

    Inflorescence development is a key factor of plant productivity, as it determines flower number. Therefore, understanding the mechanisms that regulate inflorescence architecture is critical for reproductive success and crop yield. In this study, a new mutant, vegetative inflorescence (mc-vin), was isolated from the screening of a tomato (Solanum lycopersicum L.) T-DNA mutant collection. The mc-vin mutant developed inflorescences that reverted to vegetative growth after forming two to three flowers, indicating that the mutated gene is essential for the maintenance of inflorescence meristem identity. The T-DNA was inserted into the promoter region of the MACROCALYX (MC) gene; this result together with complementation test and expression analyses proved that mc-vin is a new knock-out allele of MC. Double combinations between mc-vin and jointless (j) and single flower truss (sft) inflorescence mutants showed that MC has pleiotropic effects on the reproductive phase, and that it interacts with SFT and J to control floral transition and inflorescence fate in tomato. In addition, MC expression was mis-regulated in j and sft mutants whereas J and SFT were significantly up-regulated in the mc-vin mutant. Together, these results provide new evidences about MC function as part of the genetic network regulating the development of tomato inflorescence meristem.

    VIN usual type appears to be related to the HPV's oncogenic types. The aim of this prospective multicenter study was to evaluate the re-infection rate of high-risk HPV and the recurrence rate of VIN usual type after surgical treatment. The study enrolled 103 women affected by VIN usual type. They underwent wide local excision by CO2 laser. The patients were investigated by clinical evaluation and HPV DNA test 6 months after surgical treatment, and then were followed-up at 12, 18, 24, and 36 months. The recurrences were treated with re-excision. The rate of HPV infection after surgical treatment was 34% at 6 months, 36.9% at 12 months, 40% at 18 months, 41.7% at 24 months and 44.7% at 36 months. The mean time from HPV infection to the development of VIN was 18.8 months. HPV testing in the follow-up of VIN usual type patients might be useful for identifying those patients with a higher risk of recurrence after surgical treatment, although more studies are needed. These preliminary data suggest that the test, in addition to clinical examination, can improve the efficacy of the follow-up.

    Full Text Available Landslides threaten Vinča, a world famous archaeological site of Neolithic culture. For this reason, a field investigation and geologic-geotechnical research of the cores of seven exploration boreholes were carried out. Avery interesting structural setting was identified. The oldest stratigraphic unit consists of Middle Miocene Sarmatian sediments, which were discovered along the right bank of Danube River and within its riverbed about 300 m upstream from the archaeological site. These Sarmatian strata give evidence that the Danube River eroded the right bank. In addition, within its recent valley, there is a fault zone along which a block on the right bank was uplifted while a block on the left bank of the river that was subsided. All the boreholes passed through sediments of a previously unknown geological formation. It lies unconformably over Sarmatian strip marls and makes the base for Pleistocene loessoid sediments (approx. 10 m under the surface. These sediments were formed in a marsh-lake environment with a strong river influence. According to its superposition, the supposed age of this formation is the Plio-Pleistocene. Above the right bank of the Danube River, there are steep sections where Pleistocene swamp loessoid sediments were found. True loess deposits are not present here, but are in the hinterland of the right bank of the Danube River. The loess delluvium was deposited over the Pleistocene sediments. On the right bank of the Danube River, below the archaeological site, there are the anthropogenic water compacted sands that were previously incorrectly shown on geological maps as alluvial fans.

  8. Silencing the vacuolar invertase gene GhVIN1 blocks cotton fiber initiation from the ovule epidermis, probably by suppressing a cohort of regulatory genes via sugar signaling.

    Cotton fibers, the most important source of cellulose for the global textile industry, are single-celled trichomes derived from the ovule epidermis at or just prior to anthesis. Despite progress in understanding cotton fiber elongation and cell-wall biosynthesis, knowledge regarding the molecular basis of fiber cell initiation, the first step of fiber development determining the fiber yield potential, remains elusive. Here, we provide evidence that expression of a vacuolar invertase (VIN) is an early event that is essential for cotton fiber initiation. RNAi-mediated suppression of GhVIN1, a major VIN gene that is highly expressed in wild-type fiber initials, resulted in significant reduction of VIN activity and consequently a fiberless seed phenotype in a dosage dependent manner. The absence of a negative effect on seed development in these fiberless seeds indicates that the phenotype is unlikely to be due to lack of carbon nutrient. Gene expression analyses coupled with in vitro ovule culture experiments revealed that GhVIN1-derived hexose signaling may play an indispensable role in cotton fiber initiation, probably by regulating the transcription of several MYB transcription factors and auxin signaling components that were previously identified as required for fiber initiation. Together, the data represent a significant advance in understanding the mechanisms of cotton fiber initiation, and provide the first indication that VIN-mediated hexose signaling may act as an early event modulating the expression of regulatory genes and hence cell differentiation from the ovule epidermis. © 2014 The Authors The Plant Journal © 2014 John Wiley & Sons Ltd.

Retrospective chart review of 65 consecutive patients diagnosed with VIN 3 between 1989 and 1999. All patients diagnosed with VIN 3 at Christchurch Womens' Hospital (1 January 1989 to 31 December 1999) and Dunedin Public Hospital (1 January 1990 to 31 December 1999). Age at diagnosis, symptoms, medical history disease characteristics, treatment, outcome and follow-up. The median age at diagnosis was 38 years. Smokers were younger than non-smokers. Two-thirds had associated dysplasia of the lower genital tract, 43% had high-grade lesions. Seventy-nine per cent were symptomatic for a median of 9.5 months. All had macroscopically visible disease. Colposcopy and histology diagnoses correlated in 72% of cases. Treatment by local excision was undertaken in 84% of cases of which 65% had involved margins. Fifty-one per cent required further treatment, risk factors were positive margins and multifocal disease. Three developed micro-invasive cancer. Treatment by local excision is both diagnostic and therapeutic. Excision may reveal micro-invasive cancer, patients are usually symptomatic and VIN 3 has some potential to become invasive. Treated patients may develop microinvasive disease but frank invasion was not seen. The true rate of malignant progression in untreated patients remains unclear and radical surgery is rarely indicated. All patients require long-term follow up.

Forty early, 78 classic, 30 hypertrophic vulvar LS, 26 paediatric vulvar and penile LS, 33 vulvar LS-associated SCC and 30 vulvar/penile control specimens were examined for p53 expression and the presence of d-VIN. Nuclear p53 staining was observed in 175/207 LS biopsy specimens. Eighty percent of early and 69% of paediatric LS showed discontinuous/continuous p53 staining in basal keratinocytes. Classic LS showed no p53 staining in 17%, discontinuous basal keratinocyte staining in 20%, continuous basal keratinocyte staining in 58%, basal/suprabasal staining in 5%. Hypertrophic LS revealed basal keratinocyte staining in 32% and basal/suprabasal staining in 61%. p53 staining was associated with sclerosis of blood vessels and dermis, lymphoid infiltrates, vasculitis and hypertrophic LS. d-VIN was seen in 2% of LS alone and in 24% of LS-associated SCC. d-VIN in LS is rare, while p53 staining is common and best explained as an ischaemic stress response due to poor oxygenation, vasculitis and inflammation rather than as a marker of a precancerous lesion in LS.

    It has been proposed that low-grade vulvar and vaginal lesions (VIN 1 and VaIN 1) are flat condylomas and should be designated as such. Moreover, their relationship to high-grade lesions (VIN 3 and VaIN 3) is unclear. Accordingly, this study was undertaken to address these issues by comparing the distribution of human papillomavirus (HPV) types in vulvar and vaginal intraepithelial lesions. We identified 33 cases of VIN 1, 34 cases of VIN 3, 17 cases of VaIN 1, and 16 cases of VaIN 3. In addition, 36 cases of low-grade squamous intraepithelial lesion (LSIL) in the cervix and 116 cases of cervical high-grade squamous intraepithelial lesion were used for comparison. Polymerase chain reaction analysis was performed using both the Roche PGMY and DDL SPF 10 systems. In cases where HPV was detected, the majority of low-grade and high-grade lesions contained a single HPV type. However, a minority of cases were found to have multiple HPV types. Of the VIN 1 cases, a low-risk virus was seen in 22 (67%), with HPV 6 or 11 accounting for 14 (42%). A high-risk virus was detected in 14 (42%) of cases of which 2 (6%) contained HPV 16. Of the VIN 3 cases, all had high-risk HPV of which 31 (91%) were found to have HPV 16. Of the VaIN 1 cases, 6 (35%) were found to have low-risk HPV types. HPV 6 or 11 were not found in these cases. High-risk virus was seen in 13 (76%) VaIN 1 cases, with 1 (6%) containing HPV 16. HPV was detected in 15 of 16 (94%) VaIN 3 lesions, all of which had high-risk types. HPV 16 was found in 8 (50%). In contrast, 2 (6%) of cervical LSIL had low-risk HPV (HPV 6 and 11), whereas 34 (94%) of LSIL cases had high-risk HPVs. Of the cervical high-grade squamous intraepithelial lesion cases, 100% had high-risk HPVs of which 87 (75%) were found to have HPV 16. The findings demonstrate that a significant number of low-grade vulvar and vaginal lesions contain high-risk HPV types, supporting their designation as low-grade intraepithelial lesions rather than flat

    Full Text Available Des liens étroits existent depuis longtemps entre les vins andalous de Jerez (« sack », « sherry »,… et une forme particulière de capitalisme et de grand commerce international. Les vins de Jerez étaient consommés de par le monde bien avant « l’âge de la globalisation ». Aussi avaient-ils trouvé un certain nombre de fonctions dans de nombreuses sociétés, où ils se faisaient symboles du bon goût ou de mode de vie particulier. Ils ont nourri bien des imaginaires, comme le rappellent des créations artistiques et publicitaires, songeons au taureau de chez Osborne. Aborder ces créations d’un point de vue anthropologique conduit à une réflexion sur la complexe relation qui s’établit entre le vin et la construction des identités spatialisées, locales comme globales. Les usages symboliques du xérès diffèrent selon qu’ils soient andalous, espagnols ou britanniques ; mais tous contribuent, à leur manière, à la construction d’identités.Some very old links exist between the Andalusian wines of Jerez ("sack", "sherry"... and particular forms of capitalism and of international trade. Sherries were consumed throughout the world before the "age of globalization". So, they have found certain functions in numerous societies: symbol of good taste or of a specific way of live, etc. They have nourished imaginaries as some artistic creations from literature to advertising – the Osborne’s bull – show. Studying these creations in an anthropological point of view leads to think about the complexity of the relation between a wine and the making of spatial identities in a local or global scale. Andalusian, Spanish or British symbolic uses of Sherry are different, but all contribute, by various ways, to the building of identities.

  15. The spatial and urban planning concerns related to nuclear facilities locations: Case study of the Vinča Institute location

    2017-01-01

    Full Text Available The spatial and urban planning is one of the key instruments for the planned formation and development of locations for nuclear facilities, especially in terms of meeting the strict spatial conditionality, as well as in terms of the formation of protection zones in their surroundings. This paper systemizes the international criteria and requirements for the locations of nuclear facilities and analyses the spatial distribution of nuclear facilities in the surrounding countries of the Republic of Serbia. The research was conducted on the example of the location of the Vinča Institute of Nuclear Sciences, within which the fulfilment of spatial requirements, treatment of the location in the existing spatial and urban plans and relationship between other functions in the surrounding area were analysed. The paper proves the starting hypothesis that the general requirements related to both the spatial development of nuclear facilities locations and the protection from radiation have not been met in the Vinča location and its surroundings. It was determined that the spatial and urban plans encompassing the area of Vinča do not contain sufficiently specific planning solutions and that, as such, they do not provide a sufficient planning basis for meeting the necessary requirements and obligations regarding the protection from radiation. The paper also gives recommendations for further spatial development and protection of the Vinča location and its surroundings. The research condcted in this paper indicates the importance and priority of further research so that the necessary planning solutions for further development of the complex in Vinča and for the formation of protection zones could be defined through creating a new planning documentation. In addition, the paper particularly highlights the need for conducting a research to identify a location for permanent disposal of radioactive waste. It also indicates the necessity of considering the aspects

    2012-01-01

    Full Text Available The analysis of macro-botanical remains from the late Neolithic site of Vinča-Belo Brdo has provided first information on the range of crops and wild plants present at the site, and revealed their potential role as foodstuffs. The abundance and distribution of certain plant taxa across different archaeological deposits suggests to what extent they were used within the settlement. The analyzed plant remains also offer insight into the types of food consumed by Vinča residents and serve as a basis for inferring the seasonality and method of food provision/production and activities related to plant use.

  20. A tentative attempt to estimate the systemic number of the Late Neolithic Vinča culture figurines

    2016-03-01

    Full Text Available In this paper an attempt is made to estimate the number of figurines which were in "use" in households of the Late Neolithic Vin!a culture. The number of accumulated figurines and houses is used as a starting point. Given the complexities of the settlement dynamic, figurine use and the formation processes of the archaeological record, the ratio of the number of accumulated of figurines to the number of accumulated houses is only an indirect reflection of the systemic number of figurines. Different figurine use scenarios are evaluated in order to see what the result would be. Keeping in mind that the entire analytical procedure is highly speculative and the range of tested models is far from exhaustive, the results suggest that scenarios resting on the assumption that there was a single figurine per household and that the average use-life of the figurine was equal to the average human generation length predict outcomes that are comparable to the actual archaeological situation.

    Androgen ablation is the standard treatment for advanced prostate cancer. However, most patients will eventually develop progressive hormone-refractory prostate cancer (HRPC). The aim of the Pacl-Vin study was to determine the efficacy and safety of paclitaxel in combination with vinorelbine in patients with HRPC, following from a phase I trial. Thirty castrate patients with progressive, metastatic prostate cancer were enrolled. Patients were treated with paclitaxel 40 mg/m2, vinorelbine 20 mg/m2 intravenously on day 1 and day 8 of a 21-day cycle. Two patients demonstrated a partial response and seven patients had stable disease from a cohort of 10 patients with measurable disease. Of 30 patients assessable for prostate-specific antigen (PSA) response, 19 showed stable disease, which was maintained for at least 4 weeks, while six (20%) experienced>or=50% decline in PSA levels. Median overall survival was 7.3 months (interquartile range (IQR): 4.7-9.9 months). Median progression-free survival was 3.3 months (IQR: 2.5-7.0 months). Improvement in quality of life measures was noted after three cycles of therapy. Grade 3 and 4 toxicities were: neutropenia 8%, febrile neutropenia 4%, infection 2%, anaemia 3%, lethargy 1% and somnolescence 1%. One patient died as a result of neutropenic sepsis. In a poor prognostic cohort of patients paclitaxel and vinorelbine is a tolerable regimen, with a 20% PSA and objective response rate. The majority of patients achieved PSA stability. Furthermore, quality of life parameters, such as pain, were improved. However, the low level of activity of this regimen precludes its further testing.

    First principles calculations are reported on perpendicular magnetic anisotropy (PMA) in nearly fully compensated ferrimagnetic Heusler compound Mn0.75Co1.25VIn. The structural, electronic and magnetic properties of Mn2-xCoxVIn Heusler compounds (x = 0.0, 0.25, 0.50, 0.75, 1.0, 1.25, and 1.75) have been investigated using Density Functional theory (DFT) as implemented in the Vienna ab initio simulation package (VASP). The Perdew Burke Ernzerhof parametrization of the generalized gradient approximation (GGA) was used to treat the exchange and correlation in the system. The crystal structure of the compounds with x = 0.75, 1.00 and 1.25 are found to be tetragonally distorted. While the former exhibits inplane magnetocrystalline anisotropy (IMA) energy of 0.035 meV, the latter two exhibit perpendicular magnetocrystalline anisotropy (PMA) energy of 11.700 meV and 96.800 meV respectively. Additionally, the magnetic moments for x = 0.75 and 1.25 are found to be ∼0.5 μB/f.u. while for x = 1.00, it is found to be ∼0 μB/f.u., in agreement with the Slater Pauling rule for half metallic systems. Through Co replacement of Mn in Mn2VIn which is not half metallic at the optimized volume, a composition whose crystal structure is tetragonally distorted is found, which is not only a highly spin polarized nearly fully compensated ferrimagnet but also exhibits PMA.

  5. Chaotic He-Ne laser

    A He-Ne laser is an example of a class A laser, which can be described by a single nonlinear differential equation of the complex electric field. This laser system has only one degree of freedom and is thus inherently stable. A He-Ne laser can be driven to the chaotic condition when a large fraction of the output beam is injected back to the laser. In practice, this can be done simply by adding an external mirror. In this situation, the laser system has infinite degrees of freedom and therefore it can have a chaotic attractor. We show the fundamental laser equations and perform elementary stability analysis. In experiments, the laser intensity variations are measured by a simple photodiode circuit. The laser output intensity time series is studied using nonlinear analysis tools which can be found freely on the internet. The results show that the laser system with feedback has an attractor of a reasonably high dimension and that the maximal Lyapunov exponent is positive, which is clear evidence of chaotic behaviour. The experimental setup and analysis steps are so simple that the studies can even be implemented in the undergraduate physics laboratory.

    The vast majority of wine fermentations are performed principally by Saccharomyces cerevisiae. However, there are a growing number of instances in which other species of Saccharomyces play a predominant role. Interestingly, the presence of these other yeast species generally occurs via the formation of interspecific hybrids that contain genomic contributions from both S. cerevisiae and non-S. cerevisiae species. However, despite the large number of wine strains that are characterized at the genomic level, there remains limited information regarding the detailed genomic structure of hybrids used in winemaking. To address this, we describe the genome sequence of the thiol-releasing commercial wine yeast hybrid VIN7. VIN7 is shown to be an almost complete allotriploid interspecific hybrid that is comprised of a heterozygous diploid complement of S. cerevisiae chromosomes and a haploid Saccharomyces kudriavzevii genomic contribution. Both parental strains appear to be of European origin, with the S. cerevisiae parent being closely related to, but distinct from, the commercial wine yeasts QA23 and EC1118. In addition, several instances of chromosomal rearrangement between S. cerevisiae and S. kudriavzevii sequences were observed that may mark the early stages of hybrid genome consolidation. © 2011 Federation of European Microbiological Societies.

  9. Yours ever... or who was Katherine Brown? Investigations of prehistoric Vinča and British influences during and after World War I

    2016-11-01

    Full Text Available As the 110th anniversary of the beginning of the excavations at Vinča is nearing, the question arises as to how much we really know about the role and motives of a number of British subjects who in various ways played decisive roles in the research and the international affirmation of this important Late Neolithic site. It is possible, on the basis of archives and personal correspondence of Miloje M. Vasić, to view the investigations of Vinča in the wider context of political and military relations, influencing the general situation in the Kingdom of The Serbs, Croats and Slovenes, later Yugoslavia. John Lynton Myres was a professor at the universities in Oxford and Liverpool, the founder and editor of the Journal Man and the director of the British Archaeological School in Athens. During the World War I, between 1916 and 1919, he was an officer of the Royal Navy Volunteer Reserve, first in the Navy Intelligence Service, and then in Military Control Office in Athens. The Browns, Alec and Catherine, also played an important role. Alec Brown, a left-oriented writer, translator and correspondent, arrived to Serbia as a Cambridge graduate, aiming at the post of an English language teacher in high schools. In the period from 1929 to 1931 he took part in the excavations at Vinča, taking this setting as the base for the plot of one of his books. His wife, Elsie Catherine Brown, whose life is very poorly documented, served in the British Embassy in Belgrade between the wars. Vasić dedicated the third volume of Prehistoric Vinča to her, for her devoted work in the British medical mission and the care she took of the Serbian soldiers near Thessalonica, but also for her part played in the establishment of the initial contact with Sir Charles Hyde. The life of Catherine Brown may be seen as one of the many exceptional stories about the noble British ladies, celebrated in Serbia for over a century. However, one should bear in mind that the events and

    The aim of this study was to compare the immunohistochemical expression of vascular endothelial growth factors VEGF-C and D, as well as the expression of VEGFR-3 in VIN and vulvar invasive cancer and to compare the density of lymphatic marker D2-40 antibody in both groups, and to compare them with different clinicopathologic features. The study was performed using tissue material and clinical data from 100 women diagnosed with VIN and 100 women diagnosed with invasive vulvar cancer. No significant differences were found in the expression of VEGF-C and -D or VEGFR-3 between those patients with VIN and those with invasive vulvar cancers. Weak expression of VEGF-C was confirmed only in two cases of the analyzed series; in all cases, expression of VEGF-D and VEGFR-3 was observed. The strongest expression of VEGF-D and VEGFR-3 was observed in the group of invasive cancers. The highest density of lymphatic vessels per 2 mm was observed in VIN. In the cancer group, small lymphatic vessels with a narrow oval lumen were observed. Moreover, in two cases of vulvar cancer, the presence of intratumoral lymphatic vessels was observed. These results suggest that lymphangiogenesis begins at the preinvasive stage of vulvar carcinogenesis and suggests the important role of VEGF-C, VEGF-D, VEGFR-3 and LV (D2-40) as prognostic factors in the process of carcinogenesis in the vulvar area.

    The MiniBooNE neutrino detector was designed and built to look for ν→ν oscillations in the (sin 2θ,Δm) parameter space region where the LSND experiment reported a signal. The MiniBooNE experiment used a beam energy and baseline that were an order of magnitude larger than those of LSND so that the backgrounds and systematic errors would be completely different. This paper provides a detailed description of the design, function, and performance of the MiniBooNE detector.

    The red grape Vitis vinífera is an important source of phenolic compounds, which can prevent disease if included as a part of a diet. The levels of these compounds in grapes have been associated with various environmental factors, such as climate, soil composition, and biotic stress. The purpose of this study was to determine the relationship between the elemental compositions of the soil and the grapes and the presence of bioactive compounds, such as catechin, epicatechin, piceid and resveratrol. Ethanol-based extracts of red grapes were used to quantify total and individual phenolic compounds by HPLC. It was observed that the elemental compositions of the soil and the grapes were related to their locations within different wine-producing regions. A principal component analysis showed a relationship between high metal content (Sr, Mn, Si and Pb) and higher concentrations of antioxidants in the grapes. Copyright © 2016 Elsevier Ltd.

    NeXus is an effort by an international group of scientists to define a common data exchange and archival format for neutron, X-ray and muon experiments. NeXus is built on top of the scientific data format HDF5 and adds domain-specific rules for organizing data within HDF5 files, in addition to a dictionary of well defined domain-specific field names. The NeXus data format has two purposes. First, it defines a format that can serve as a container for all relevant data associated with a beamline. This is a very important use case. Second, it defines standards in the form of application definitions for the exchange of data between applications. NeXus provides structures for raw experimental data as well as for processed data.

  18. Is any awareness necessary for an Ne?

    Full Text Available The Error-Related Negativity (Ne or ERN is a reliable electrophysiological index of error processing, which has been found to be independent of whether a subject is aware of an error or not. A large Ne was equally seen after errors that were consciously detected (Aware errors and those that were not (Unaware errors, compared to a small negativity for correct responses (CRN. This suggests a dissociation between an automatic, preconscious error processing mechanism and subjective evaluation. A common concern regarding this finding is that subjects could have been somewhat aware of their errors, but did not report them due to lack of confidence. Here we tested this possibility directly using a betting paradigm which allowed us to separate occasions in which the subjects were confident of their response and trials in which they were unsure. In a choice reaction time task, subjects directly judged the accuracy of each response (correct or error and then bet on this judgment using a high, medium or low amount of money. The bets were used to determine the level of confidence the subjects had of their response. The average across all subjects regardless of confidence (betting measure replicated the reported finding of an equal Ne for Aware and Unaware errors which was larger than the CRN. However, when Ne measurement was confined to high confidence (high bet trials in confident subjects, a prominent Ne was seen only for Aware errors, while confident Unaware errors (i.e., error trials on which subjects made high bets that they were correct elicited a response that did not differ from the CRN elicited by truly correct answers. In contrast, for low confidence trials in unconfident subjects, an intermediate and equal Ne/CRN was elicited by Correct responses, Aware and Unaware errors. These results provide direct evidence that the Ne is related to error awareness, and suggest the amplitude of the Ne/CRN depends on individual differences in error reporting

    Two isotopic chemical reactions, Ne(*) + NH3, and Ne(*) + ND3, have been studied at low collision energies by means of a merged beams technique. Partial cross sections have been recorded for the two reactive channels, namely, Ne(*) + NH3 → Ne + NH3(+) + e(-), and Ne(*) + NH3 → Ne + NH2(+) + H + e(-), by detecting the NH3(+) and NH2(+) product ions, respectively. The cross sections for both reactions were found to increase with decreasing collision energy, Ecoll, in the range 8 μeV NH3 reaction in the entire range of collision energies covered here. Calculations based on multichannel quantum defect theory were performed to reproduce and interpret the experimental results. Good agreement was obtained by including long range van der Waals interactions combined with a 6-12 Lennard-Jones potential. The branching ratio between the two reactive channels, Γ = [NH2(+)]/[NH2(+)] + [NH3(+)], is relatively constant, Γ ≈ 0.3, in the entire collision energy range studied here. Possible reasons for this observation are discussed and rationalized in terms of relative time scales of the reactant approach and the molecular rotation. Isotopic differences between the Ne(*) + NH3 and Ne(*) + ND3 reactions are small, as suggested by nearly equal branching ratios and cross sections for the two reactions.

    Full Text Available The international restructuring process in the beverage sector reached the winemaking business in the 1990s, changing its panorama. Increasing competitive pressure is a characteristic of this period with significant impact in regions such as the countries belonging to the Mercosul block. To support firm strategies and public policies, the goal of this study was to identify the competition segments in winemaking in Rio Grande do Sul, the southern state of Brazil, and in a specific form to propose a typology of wineries based on the Industrial Organization literature. The data used are from the State Wineries Data Bank of Rio Grande do Sul, which were submitted to multivariate statistical analysis, integrating a cluster and principal components analysis in a group of 381 observations. The results showed the existence of two factors, one related to scale and diversification, and the other related to the quality of the products and of the raw material. From these factors, six groups of wineries were identified that can be named segments of competition in winemaking. Group 1 is characterized by quality and specialization; group 2, by a large production scale and diversification; group 3, by a low added value; group 4, by a micro production scale; and groups 5 and 6, by a low added value, small scale, and specialization.O processo de reestruturação internacional no setor de bebidas atingiu a vitivinicultura na década de 1990, alterando o seu panorama.

    Full Text Available The RTS (Real-Time Systems are widely used in industry, home appliances, life saving systems, aircrafts, and automatic weapons. These systems need more accuracy, safety, and reliability. An accurate graphical modeling and verification of such systems is really challenging. The formal methods made it possible to model such systems with more accuracy. In this paper, we envision a strategy to overcome the inadequacy of SysML (System Modeling Language for modeling and verification of RTS, and illustrate the framework by applying it on a case study of fuel filling machine. We have defined DC (Duration Calculus implementaion based formal semantics to specify the functionality of RTS. The activity diagram in then generated from these semantics. Finally, the graphical model is verified using UPPAAL and DiVinE model checkers for validation of timed and untimed properties with accelerated verification speed. Our results suggest the use of methodology for modeling and verification of large scale real-time systems with reduced verification cost.

    The Network-extracted Ontology (NeXO) is a gene ontology inferred directly from large-scale molecular networks. While most ontologies are constructed through manual expert curation, NeXO uses a principled computational approach which integrates evidence from hundreds of thousands of individual gene and protein interactions to construct a global hierarchy of cellular components and processes. Here, we describe the development of the NeXO Web platform (http://www.nexontology.org)-an online database and graphical user interface for visualizing, browsing and performing term enrichment analysis using NeXO and the gene ontology. The platform applies state-of-the-art web technology and visualization techniques to provide an intuitive framework for investigating biological machinery captured by both data-driven and manually curated ontologies.

    2017-04-01

    Full Text Available Galileo adopts NeQuick model for single-frequency ionospheric delay corrections. For the standard operation of Galileo, NeQuick model is driven by the effective ionization level parameter Az instead of the solar activity level index, and the three broadcast ionospheric coefficients are determined by a second-polynomial through fitting the Az values estimated from globally distributed Galileo Sensor Stations (GSS. In this study, the processing strategies for the estimation of NeQuick ionospheric coefficients are discussed and the characteristics of the NeQuick coefficients are also analyzed. The accuracy of Global Position System (GPS broadcast Klobuchar, original NeQuick2 and fitted NeQuickC as well as Galileo broadcast NeQuickG models is evaluated over the continental and oceanic regions, respectively, in comparison with the ionospheric total electron content (TEC provided by global ionospheric maps (GIM, GPS test stations and JASON-2 altimeter. The results show that NeQuickG can mitigate ionospheric delay by 54.2%~65.8% on a global scale, and NeQuickC can correct for 71.1%~74.2% of the ionospheric delay. NeQuick2 performs at the same level with NeQuickG, which is a bit better than that of GPS broadcast Klobuchar model.

    2014-09-01

    Tension among recent short baseline neutrino experiments has pointed toward the possible need for the addition of one or more sterile (non-interacting) neutrino states into the existing neutrino oscillation framework. This thesis first presents the motivation for sterile neutrino models by describing the short-baseline anomalies that can be addressed with them. This is followed by a discussion of the phenomenology of these models. The MiniBooNE experiment and results are then described in detail, particularly the most recent antineutrino analysis. This will be followed by a discussion of global fits to world data, including the anomalous data sets. Lastly, future experiments will be addressed, especially focusing on the MicroBooNE experiment and light collection studies. In particular, understanding the degradation source of TPB, designing the TPB-coated plates for MicroBooNE and developing lightguide collection systems will be discussed. We find an excess of events in the MiniBooNE antineutrino mode results consistent with the LSND anomaly, but one that has a different energy dependence than the low-energy excess reported in neutrino mode. This disagreement creates tension within global fits which include up to three sterile neutrinos. The low-energy excess will be addressed by the MicroBooNE experiment, which is expected to start taking data in early 2015. Tension among existing experiments calls for additional, more decisive future experiments.

Le développement de l'énergie électrique nucléaire, qui actuellement s'impose économiquement, implique, pour élargir la pénétration de cette forme d'énergie à toutes les utilisations, une énergie chimique relais permettant un stockage et une régulation de la production; l'hydro- gène obtenu par électrolyse de l'eau semble pouvoir constituer ce combustible relais dans un délai raisonnable en tenant compte des contraintes de pollution.

    NE Lau Response Team: K Rubin, E Baker, J Lupton, M Lilley, T Shank, S Merle, R Dziak, T Collasius (Jason 2 Expedition Leader), N Buck, T Baumberger, D Butterfield, D Clague, D Conlin, J Cowen, R Davis, L Evans, J Huber, M Keith, N Keller, P Michael, E Podowski, A-L Reysenbach, K Roe, H Thomas, S Walker. During a May 2009 cruise to W Mata volcano in the NE Lau Basin, we made the first observations of an active eruption on the deep-sea floor. The cruise was organized after volcanic activity was detected at two sites (W Mata volcano and NE Lau Spreading Center, NELSC) during a Nov. 2008 NOAA-PMEL expedition. At that time, both sites had elevated H2 concentrations and volcaniclastic shards in the hydrothermal plumes. Moored hydrophone data since Jan 2009 indicate that the activity at W Mata has been continuous between these expeditions. Results of our cruise and other work suggest that the NE Lau Basin hosts an unusually high level of magmatic activity, making it an ideal location to study the effects of magmatic processes on hydrothermal activity and associated ecosystems. W Mata was visited with 5 ROV Jason 2 dives and 2 dives with the MBARI autonomous mapping vehicle in May 2009. It was actively erupting at the 1200 m deep summit during each, so a hydrophone was deployed locally to collect acoustic data. Ship and shore-based analysis of HD video, molten lava, rocks, sediments, hot spring waters, and micro- and macro biological specimens collected by Jason 2 have provided a wealth of data. The eruption itself was characterized by extrusion of red, molten lava, extensive degassing, formation of large magma bubbles, explosive pyroclast ejection, and the active extrusion of pillow lavas. The erupting magmas are boninite, a relatively rare magma type found only at convergent margins. The hydrothermal fluids are generally acidic and all diffuse fluids collected were microbially active, even those at pH shrimp similar to those found at several other submarine volcanoes

    By using He-Ne laser treatment, 84.7 - 91.1% of patients with menorrhagia, a common symptom of multiple gynecological diseases, are treated effectively. After laser irradiation, the amount of vaginal bleeding was reduced 47.1% on average. It has been proven that low-energy laser is an effective non-traumatic, painless, and easily acceptable new physical method in patients with menorrhagia. To study the mechanisms of efficiency, the quantitative determination of PGE2, PGF2(alpha ), 6-Keto-PGF1(alpha ), TXB2 in endometrium and blood flow before and after treatment were carried out. The results suggest that the effectiveness may be due to the recovery regulation of local uterine PGS level.

    2008-10-01

    Simplex vulvar intraepithelial neoplasia (VIN) is an important precursor of vulvar invasive squamous cell carcinoma and characteristically occurs in postmenopausal women. In this report, the absence of high-risk human papillomavirus (HPV) combined with specific p53 and p16INK4a expression patterns points to the HPV-independent pathway as the causative agent for vulvar squamous cell carcinoma in a 28-year-old woman. Its precursor simplex VIN was initially interpreted as eczema. Although simplex VIN has a predilection for postmenopausal women, it can occur in young patients. The development of invasive vulvar squamous cell carcinoma underlines the importance of including simplex VIN in the differential diagnosis of vulvar lesions, even at a young age. Furthermore, knowledge about the HPV status in the tumor and thus the underlying causative pathway can alert the gynecologist for the presence or absence of multicentric lower genital tract disease, as this is frequent in the HPV-dependent and not in the HPV-independent pathway.

    The primary physics goal of Mini BooNE is to confirm or rule out the LSND vμ→ve oscilliation observation with high significance. In the 2003 Run Plan document presented to the PAC, we outlined the need for 1 X 1021 protons on target (POT) to achieve this goal. In this document, we present an addendum to our run plan for fiscal year 2006 (FY2006).

    One-neutron knockout reactions of Ne24-28 in a beryllium target have been studied in the Fragment Separator (FRS), at GSI. The results include inclusive one-neutron knockout cross-sections as well as longitudinal-momentum distributions of the knockout fragments. The ground-state structure of the neutron-rich neon isotopes was obtained from an analysis of the measured momentum distributions. The results indicate that the two heaviest isotopes, Ne-27 and Ne-28, are dominated by a configuration in which a s(1/2) neutron is coupled to an excited state of the Ne-26 and Ne-27 core, respectively.

  10. Between the Vinča andLinearbandkeramikWorlds: The Diversity of Practices and Identities in the 54th-53rd Centuries cal BC in Southwest Hungary and Beyond.

    Perhaps nowhere in European prehistory does the idea of clearly-defined cultural boundaries remain more current than in the initial Neolithic, where the southeast-northwest trend of the spread of farming crosses what is perceived as a sharp divide between the Balkans and central Europe. This corresponds to a distinction between the Vinča culture package, named for a classic site in Serbia, with its characteristic pottery assemblage and absence of longhouses, and the Linearbandkeramik (LBK), with equally diagnostic but different pottery, and its apparently culturally-diagnostic longhouses, extending in a more northerly belt through central Europe westward to the Dutch coast. In this paper we question the concept of such a clear division through a presentation of new data from the site of Szederkény-Kukorica-dűlő. A large settlement in southeast Transdanubia, Hungary, excavated in advance of road construction, Szederkény is notable for its combination of pottery styles, variously including Vinča A, Ražište and LBK, and longhouses of a kind otherwise familiar from the LBK world. Formal modelling of its date establishes that the site probably began in the later 54th century cal BC, lasting until the first decades of the 52nd century cal BC. Occupation, featuring longhouses, pits and graves, probably began at the same time in the eastern and western parts of the settlement, starting a decade or two later in the central part; the western part was probably the last to be abandoned. Vinča pottery is predominantly associated with the eastern and central parts of the site, and Ražište pottery with the west. Formal modelling of the early history of longhouses in the LBK world suggests their emergence in the Formative LBK of Transdanubia c. 5500 cal BC followed by rapid dispersal in the middle of the 54th century cal BC, associated with the 'earliest' ( älteste ) LBK. The adoption of longhouses at Szederkény thus appears to come a few generations after the start

    Initial state selected dynamics of the Ne + NeH{sup +}(v{sub 0} = 0, j{sub 0} = 0) → NeH{sup +} + Ne reaction is investigated by quantum and statistical quantum mechanical (SQM) methods on the ground electronic state. The three-body ab initio energies on a set of suitably chosen grid points have been computed at CCSD(T)/aug-cc-PVQZ level and analytically fitted. The fitting of the diatomic potentials, computed at the same level of theory, is performed by spline interpolation. A collinear [NeHNe]{sup +} structure lying 0.72 eV below the Ne + NeH{sup +} asymptote is found to be the most stable geometry for this system. Energies of low lying vibrational states have been computed for this stable complex. Reaction probabilities obtained from quantum calculations exhibit dense oscillatory structures, particularly in the low energy region and these get partially washed out in the integral cross section results. SQM predictions are devoid of oscillatory structures and remain close to 0.5 after the rise at the threshold thus giving a crude average description of the quantum probabilities. Statistical cross sections and rate constants are nevertheless in sufficiently good agreement with the quantum results to suggest an important role of a complex-forming dynamics for the title reaction.

    The collision system Ne/sup 4 +/-Ne has been studied both theoretically and experimentally. The cross section for one-electron capture into Ne/sup 3 +/(3s,3p) subshells has been determined in the velocity range 0.1-0.5 au by measuring the VUV photons emitted by these excited states. The cross sections for one- and two-electron capture into 3s, 3p subshells were calculated using a multichannel Landau-Zener model. Good agreement exists between experimental and theoretical results for one-electron capture.

Umro je 2009. u Nizozemskoj pod drugim imenom: Carlos Fuentes. Salim i njegovi kolege, puni dosade i gnušanja, kao i svakoga drugog jadnog dana, čistili su tržnicu nakon što je eksplodirao tegljač s gorivom, zapalivši piliće, voće, povrće i pokojeg čovjeka.

U potrazi za posmrtnim dragocjenostima Salim nije imao sreće kao njegovi kolege. Trebao mu je novac za vizu kako bi otišao u Nizozemsku i pobjegao iz ovog vatrenoga užasa prepunoga smrti. Samo mu se jedanput posrećilo pa je našao prst s dragocjenim srebrnim prstenom, vrlo lijepim. Salim je poklopio prst stopalom, pažljivo se sagnuo i skinuo prsten s gađenjem. Prsten je završio na Salimovoj ruci, zadivljeno je promatrao dragi kamen i na kraju odustao od pomisli da ga proda. Može li se reći da je osjetio duboku duhovnu povezanost s prstenom?

    There is accumulating evidence for a difference between neutrino and antineutrino oscillations at the {approx}1 eV{sup 2} scale. The MiniBooNE experiment observes an unexplained excess of electron-like events at low energies in neutrino mode, which may be due, for example, to either a neutral current radiative interaction, sterile neutrino decay, or to neutrino oscillations involving sterile neutrinos and which may be related to the LSND signal. No excess of electron-like events (-0.5 {+-} 7.8 {+-} 8.7), however, is observed so far at low energies in antineutrino mode. Furthermore, global 3+1 and 3+2 sterile neutrino fits to the world neutrino and antineutrino data suggest a difference between neutrinos and antineutrinos with significant (sin{sup 2} 2{theta}{sub {mu}{mu}} {approx} 35%) {bar {nu}}{sub {mu}} disappearance. In order to test whether the low-energy excess is due to neutrino oscillations and whether there is a difference between {nu}{sub {mu}} and {bar {nu}}{sub {mu}} disappearance, we propose building a second MiniBooNE detector at (or moving the existing MiniBooNE detector to) a distance of {approx}200 m from the Booster Neutrino Beam (BNB) production target. With identical detectors at different distances, most of the systematic errors will cancel when taking a ratio of events in the two detectors, as the neutrino flux varies as 1/r{sup 2} to a calculable approximation. This will allow sensitive tests of oscillations for both {nu}{sub e} and {bar {nu}} appearance and {nu}{sub {mu}} and {bar {nu}}{sub {mu}} disappearance. Furthermore, a comparison between oscillations in neutrino mode and antineutrino mode will allow a sensitive search for CP and CPT violation in the lepton sector at short baseline ({Delta}m{sup 2} > 0.1 eV{sup 2}). Finally, by comparing the rates for a neutral current (NC) reaction, such as NC {pi}{sup 0} scattering or NC elastic scattering, a direct search for sterile neutrinos will be made.

  3. Shape evolution of Ne isotopes and Ne hypernuclei: The interplay of pairing and tensor interactions

    Directory of Open Access Journals (Sweden)

    2014-03-01

    Full Text Available We study tensor and pairing effects on the quadruple deformation of neon isotopes based on a deformed Skyrme-Hartree-Fock model with BCS approximation for the pairing channel. We extend the Skyrme-Hartree-Fock formalism for the description of hypernuclei adopting the recently-proposed ESC08b hyperon-nucleon interaction. It is found that the interplay of pairing and tensor interactions is crucial to derive the deformations in several neon isotopes. Especially, the shapes of 26,30Ne are studied in details in comparisons with experimentally observed shapes. Furthermore the deformations of the hypernuclei are compared with the corresponding neon isotopic cores in the presence of tensor force. We find the same shapes with somewhat smaller deformations for single Λ-hypernuclei compared with their core deformations.

  4. The supernova neutrino readout of MicroBooNE

    Crespo Anadon, Jose Ignacio; MicroBooNE Collaboration

    2017-01-01

    The MicroBooNE detector is currently the largest liquid argon time projection chamber (LArTPC) operative worldwide. In the case of a nearby (a few kiloparsecs away) core-collapse supernova, the emitted neutrinos would induce on the order of tens of interactions within the MicroBooNE TPC. This would constitute the first detection of supernova neutrinos with the LArTPC technology, offering a unique sensitivity to the electron neutrino flux. Due to the low energy of the events (tens of MeV), the detector size (89 tons of active volume) and the location near surface, MicroBooNE cannot trigger on supernova neutrinos and therefore relies on an external alert generated by other neutrino detectors (the SuperNova Early Warning System, or SNEWS). A continuous readout is being commissioned in MicroBooNE in which the data are temporarily stored in buffers, waiting for the SNEWS alert to save them permanently. In order to cope with the large data rate produced by the TPC and the PMT systems, online zero-suppression algorithms have been developed. This talk will explain the continuous supernova readout of MicroBooNE, which is of interest to the future short and long baseline neutrino programs which will bring additional LArTPCs online in the coming years.

    The future neutrino telescope KM3NeT, to be built in the Mediterranean Sea, will be the largest of its kind. It will include nearly two hundred thousand photomultiplier tubes (PMT) mounted in multi-PMT digital optical modules (DOM). The dominant source of the PMT signals is decays of {sup 40}K and marine fauna bioluminescence. Selection of neutrino and muon events from this continuous optical background signals requires the implementation of fast and efficient triggers. Various schemes for the filtering of background data and the selection of neutrino and muon events were evaluated for the KM3NeT telescope using Monte Carlo simulations.

    2017-01-01

    Full Text Available La teoría de los mundos de producción ha ejercido una profunda influencia en los estudios sobre la geografía de los alimentos desde la década de 1990. Los mundos de producción se definen como combinaciones de decisiones adoptadas mediante la interacción entre productores y consumidores acerca de dos ejes principales: el empleo de recursos estandarizados o especializados, y la producción de bienes genéricos o dedicados. Sin embargo, la literatura derivada de esta teoría es, ante todo, cualitativa y basada en estudios de caso sobre un determinado sistema productivo agroalimentario. Este artículo desarrolla una metodología más cuantitativa para clasificar estos sistemas agroalimentarios en la tipología de los mundos de producción, tomando como respaldo empírico dieciséis comarcas vinícolas españolas respaldadas por una Denominación de Origen. Se han calculado veintiún indicadores para cada comarca a partir de datos disponibles en fuentes de acceso abierto. Siete comarcas o Denominaciones pertenecen al llamado mundo de producción interpersonal. Este resultado confirma la tendencia del modelo europeo de producción de vinos a potenciar y proteger el origen geográfico como argumento competitivo en los mercados.

    bubbles collapsing at a free surface. But, to the best of our knowledge, and surprising as it may seem, no results concerning the collateral effects on adjoining bubbles of bubbles collapsing in a bubble monolayer have been reported up to now. Actually, effervescence in a glass of champagne ideally lends to a preliminary work with bubbles collapsing in a bubble monolayer. For a few seconds after pouring, the free surface is completely covered with a monolayer composed of quite monodisperse millimetric bubbles collapsing close to each others. We took high-speed photographs of the situation which immediately follows the rupture of a bubble cap in a bubble monolayer. Adjoining bubbles were found to be literally sucked and strongly stretched toward the lowest part of the cavity left by the bursting bubble, leading to unexpected and short-lived flower-shaped structures. Stresses in distorted bubbles (petals of the flower-shaped structure) were evaluated and found to be, at least, one order of magnitude higher than stresses numerically calculated in the boundary layer around an isolated single millimetric collapsing bubble. This is a brand-new and slightly counter-intuitive result. While absorbing the energy released during collapse, as an air-bag would do, adjoining bubble caps store this energy into their thin liquid film, leading finally to stresses much higher than those observed in the boundary layer around single millimetric collapsing bubbles. Further investigation should be conducted now, and especially numerically, in order to better understand the relative influence of each pertinent parameters (bubble size, liquid density and viscosity, effect of surfactant...) on bubble deformation. L'objectif général de cet ouvrage consacré à l'étude des processus physico- chimiques de l'effervescence des vins de Champagne était de décortiquer les différentes étapes de la vie d'une bulle de champagne en conditions réelles de consommation, dans une flûte.

    Vivolo, Daniele

    2016-04-01

    KM3NeT is a European deep-sea multidisciplinary research infrastructure in the Mediterranean Sea. It will host a km3-scale neutrino telescope and dedicated instruments for long-term and continuous measurements for Earth and Sea sciences. The KM3NeT neutrino telescope is a 3-dimensional array of Digital Optical Modules, suspended in the sea by means of vertical string structures, called Detection Units, supported by two pre-stretched Dyneema ropes, anchored to the seabed and kept taut with a system of buoys. The Digital Optical Module represents the active part of the neutrino telescope. It is composed by a 17-inch, 14 mm thick borosilicate glass (Vitrovex) spheric vessel housing 31 photomultiplier tubes with 3-inch photocathode diameter and the associated front-end and readout electronics. The technical solution adopted for the KM3NeT optical modules is characterized by an innovative design, considering that existing neutrino telescopes, Baikal, IceCube and ANTARES, all use large photomultipliers, typically with a diameter of 8″ or 10″. It offers several advantages: higher sensitive surface (1260 cm2), weaker sensitivity to Earth's magnetic field, better distinction between single-photon and multi-photon events (photon counting) and directional information with an almost isotropic field of view. In this contribution the design and the performance of the KM3NeT Digital Optical Modules are discussed, with a particular focus on enabling technologies and integration procedure.

    Heid, Thomas [ECAP, FAU Erlangen-Nuernberg, Erlangen (Germany); Collaboration: ANTARES-KM3NeT-Erlangen-Collaboration

    2016-07-01

    With the installation of the first KM3NeT line, a new facility for neutrino astronomy started operation at the end of 2015. KM3NeT detectors are built of several thousands of digital optical modules(DOM) deployed in a three-dimensional grid. The DOMs receive light from particles passing the detector or created in neutrino interactions in the vicinity of the detector. A primary physics goal is to detect point-like neutrino sources. An important step in understanding the signal of astrophysical sources, is to understand the background to the measurement originating in the atmosphere. It consists of muons and neutrinos. Dedicated simulations optimized for KM3NeT have been performed. This contribution describes the simulation chain, starting with an atmospheric air shower simulation and propagating particles from the sea surface to the detector at a depth of 2.5 to 3.5 km. The nature of the background expected to most strongly affect KM3NeT's sensitivity to astrophysical neutrino fluxes is presented, as are methods for dealing with it. Besides their role as background, studying atmospheric particles can improve the understanding of particle creation in the atmosphere, especially the charm production mechanism.

  20. LabVIEW Data Acquisition for NE213 Neutron Detector

    Energy Technology Data Exchange (ETDEWEB)

    Gangadharan, Dhevan

    2003-09-23

    A neutron spectroscopy system based on a NE213 liquid scintillation detector at the Stanford Linear Accelerator Center measures neutron energies from a few MeV up to 800 MeV. The neutrons are produced from the electron beam and target interactions. The NE 213 scintillator, coupled with a Photomultiplier Tube (PMT), detects and converts radiation into electric pulses for signal processing. Signals are processed through Nuclear Instrument Modules (NIM) and Computer Automated Measurement and Control (CAMAC) modules. The processed pulses are then fed into a CAMAC analog to digital converter module (ADC). The ADC classifies the incoming analog pulses into one of 2048 digital channels. Data acquisition (DAQ) software based on LabVIEW version 7.0 acquires and organizes data from the CAMAC ADC. The DAQ system presents a spectrum showing a relationship between pulse events and respective charge (digital channel number). Various photon sources, such as Co-60, Y-88, and AmBe-241, are used to calibrate the NE213 detector. For each source, a Compton edge and reference energy in MeVee is obtained, resulting in a calibration curve. This project is focused on the development of a DAQ system and control setup to collect and process information from a NE213 liquid scintillation detector. A manual is also created to document the process of the development and interpretation of the LabVIEW-based DAQ system.

    The MiniBooNE experiment at FNAL is a neutrino νμ->νe oscillation search whose detector is a 12 m spherical oil tank lined with 1520 8 inch photomultiplier tubes, Hamamatsu models R1408 and R5912, with custom--designed bases. Tests were performed on all the phototubes to determine the dark rate, charge and timing resolutions of the response, double--pulsing rate, and desired operating voltage for each tube, so that they could be sorted for optimal use in the detector. Eight additional phototubes were tested to find the angular dependance of their response, and these results for the R1408 and R5912 phototubes were fit to 5-- and 6--degree polynomials, respectively. This test was performed again at various voltages. These fits were incorporated into the MiniBooNE Monte Carlo. After the Super--K phototube implosion accident, an analysis was performed to determine the risk of a similar accident with MiniBooNE, and the risk was found to be negligible. *MiniBooNE is an experiment at Fermi National Accelerator Laboratory

  4. Event identification for KM3NeT/ARCA

    2017-09-01

    KM3NeT is a large research infrastructure consisting of a network of deep-sea neutrino telescopes. KM3NeT/ARCA will be the instrument detecting high-energy neutrinos with energies above 100 TeV. This instrument gives a new opportunity to observe the neutrino sky with very high angular resolution to be able to detect neutrino point sources. Furthermore it will be possible to probe the flavour composition of neutrino fluxes, and hence production mechanisms, with so-far unreached precision. Neutrinos produce different event topologies in the detector according to their flavour, interaction channel and deposited energy. Machine-learning algorithms are able to learn features of topologies to discriminate them. In previous analyses only two event types were regarded, namely the shower and track topology. With good timing resolution and precise reconstruction algorithms it is possible to separate into more event types, for example the double bang topology produced by tau neutrinos. The final goal is to distinguish all three neutrino flavors as much as possible. To resolve this issue the KM3NeT collaboration uses deep neural networks trained with Monte Carlo events of all neutrino types. This contribution shows the ability of KM3NeT/ARCA to classify events in more than two neutrino event topologies. Furthermore, the borders between detectable classes are shown, such as the minimum distance the tau has to travel before decaying into a tau neutrino to be detected as double bang event.

  6. Precision angle-resolved autoionization resonances in Ar and Ne

    Berrah, N.; Langer, B.; Gorczyca, T.W. [Western Michigan Univ., Kalamazoo, MI (United States)] [and others

    1997-04-01

    Theoretical work has shown that the electron angular distribution and the shape of the autoionization resonances are crucial to the understanding of certain types of electron-electron correlation. Autoionization resonances in Ne (Ar) result from the decay of the excited discrete state Ne{sup *} 2s2p{sup 6} np (Ar{sup *} 3s3p{sup 6} np) into the continuum state Ne{sup +} 2s{sup 2}2p{sup 5} + e{sup {minus}} (ks,kd) (Ar{sup +} 3s{sup 2}3p{sup 5} + e{sup {minus}} (ks,kd)). Since the continuum can also be reached by direct photoionization, both paths add coherently, giving rise to interferences that produce the characteristic Beutler-Fano line shape. In this work, the authors report on quantitative angle-resolved electron spectrometry studies of (a) the Ne 2s{sup 2}2p{sup 6} {r_arrow} 2s2p{sup 6} np (n=3-5) autoionizing resonances and the 2s{sup 2}2p{sup 6} {r_arrow} 2p{sup 4}3s3p doubly excited resonance, (b) the Ar 3s{sup 2}3p{sup 6} {r_arrow} 3s3p{sup 6} np (n=4-9) autoionization resonances and extended R-matrix calculations of the angular-distribution parameters for both Ne and Ar measurements. Their results are compared with previous theoretical work by Taylor.

    2017-01-01

    MicroBooNE uses the Liquid Argon Time Projection Chamber (LAr TPC) technology to detect neutrino interactions from the Fermilab Booster Neutrino Beam. Traveling through the detector volume, charged particles deposit energy by ionizing the argon and create positive argon ions and electron pairs along their trajectory. The electrons can recombine with an argon ion and reform a neutral atom and, as a result, the measured energy is only a fraction of the total energy lost by the particle. This process is called electron-ion recombination. Understanding this recombination effect is particularly important for performing calorimetry, identifying particle types, and achieving good energy resolution in LAr TPCs. This talk will present the status of MicroBooNE's first recombination measurement obtained with cosmic ray data.

    Neutrino-induced neutral pion production is an important measurement for next generation neutrino oscillation experiments. Neutral current (NC) neutral pion production is a direct background for electron neutrino appearance experiments, while charged current (CC) neutral pion production affects experiments looking for muon neutrino disappearance. Located in the Booster Neutrino Beam at Fermilab, SciBooNE is a neutrino scattering experiment designed to accurately measure muon neutrino and anti-neutrino cross sections on carbon near 1 GeV neutrino energy. In this talk I will present recent SciBooNE results on neutral pion production, including the total cross section measurement for both channels relative to the CC inclusive cross section, the separation of the coherent and incoherent contributions to the NC channel, and details on neutral pion production kinematics.

    The KM3NeT readout concept is based on a point-to-point optical network connecting the 10,000 optical modules in the deep-sea neutrino telescope with the shore station. The numerous fiber optic channels arriving at the shore station will be concentrated on the shore electronics systems, which will receive, merge and time order the data, and send them to the DAQ system. Although the network functionality is bi-directional, the physical channel allocation is asymmetric; most channels are assigned to the data reception and only a few channels are used for control with data transport from shore to the telescope. We will discuss the FPGA based platform systems for the shore station and the appropriate firmware implementation for the data gathering and broadcast demands of a neutrino telescope. We will present our experiences based on FPGA evaluation platforms suitable to build a demonstrator of the KM3NeT shore station.

The NE213 scintillator, coupled with a Photomultiplier Tube (PMT), detects and converts radiation into current for signal processing. Signals are processed through Nuclear Instrument Modules (NIM) and Computer Automated Measurement and Control (CAMAC) modules. CAMAC is a computer automated data acquisition and handling system. Pulses are properly prepared and fed into an analog to digital converter (ADC), a standard CAMAC module. The ADC classifies the incoming analog pulses into 1 of 2048 digital channels. Data acquisition (DAQ) software based on LabVIEW, version 7.0, acquires and organizes data from the CAMAC ADC. The DAQ system presents a spectrum showing a relationship between pulse events and respective charge (digital channel number). Various photon sources, such as Co-60, Y-88, and AmBe-241, are used to calibrate the NE213 detector. For each source, a Compton edge and reference energy [units of MeVee] is obtained. A complete calibration curve results (at a given applied voltage to the PMT and pre-amplification gain) when the Compton edge and reference energy for each source is plotted. This project is focused to development of a DAQ system and control setup to collect and process information from a NE213 liquid scintillation detector. A manual is created to document the process of the development and interpretation of the LabVIEW-based DAQ system. Future high-energy neutron measurements can be referenced and normalized according to this calibration curve.

  3. UNIVERSAL JURISDICTION AND THE PRINCIPLE OF NE BIS IN IDEM

    Directory of Open Access Journals (Sweden)

    2011-04-01

    Full Text Available Universal jurisdiction was defined as “the assertion of jurisdiction to prescribe in the absence of any other accepted jurisdictional nexus at the time of the relevant conduct.” Professor Randall, in his seminal work on universal jurisdiction, opined that the theory of universality “provides every state with jurisdiction over a limitedcategory of offenses generally recognized as of universal concern, regardless of the situs of the offence and the nationalities of the offender and the offended. ”Universal jurisdiction is considered a tool for promoting greater justice, but the rights of the accused must be protected. One of the most important guarantees is the principle of ne bis in idem, which protected persons against multiple prosecutions for the same crime. The main legal consequence of the application of ne bis in idem in most systems is the prohibition and inadmissibility of subsequent prosecutions on the same facts blocking effect.The national ne bis in idem principle is established asan individual right in international human rights legal instruments, such as the International Covenant on Civil and Political Rights of 19 December 1966, in Article 14(7. At the regional level, Article 8(4 of the American Convention of Human Rights (1969 and Article 4 (I of the Seventh Protocol of the European Convention of Human Rights merit mention. In Europe, the ne bis in idem principle is enshrined in Article 54 of the Convention implementing the Schengen Agreement of 14 June 1985, which prohibits the initiation of a second trial for the same offence when final judgment has been imposed upon a person by a court of a contracting party.

  7. SpEED-Ne: software to simulate and estimate genetic effective population size (Ne) from linkage disequilibrium observed in single samples.

    Science.gov (United States)

    Hamilton, Matthew B; Tartakovsky, Maria; Battocletti, Amy

    2018-02-03

    The genetic effective population size, N e , can be estimated from the average gametic disequilibrium (r2^) between pairs of loci but such estimates require evaluation of assumptions and currently have few methods to estimate confidence intervals. SpEED-Ne is a suite of Matlab computer code functions to estimate Ne^ from r2^ with a graphical user interface and a rich set of outputs that aid in understanding data patterns and comparing multiple estimators. SpEED-Ne includes functions to either generate or input simulated genotype data to facilitate comparative studies of Ne^ estimators under various population genetic scenarios. SpEED-Ne was validated with data simulated under both time-forward and time-backward coalescent models of genetic drift. Three classes of estimators were compared with simulated data to examine several general questions: what are the impacts of microsatellite null alleles on Ne^, how should missing data be treated, and does disequilibrium contributed by reduced recombination among some loci in a sample impactNe^. Estimators differed greatly in precision in the scenarios examined and a widely employed Ne^ estimator exhibited the largest variances among replicate data sets. SpEED-Ne implements several jackknife approaches to estimate confidence intervals, and simulated data showed that jackknifing over loci and jackknifing over individuals provided approximately 95% confidence interval coverage for some estimators and should be useful for empirical studies. SpEED-Ne provides an open-source extensible tool for estimation of N e from empirical genotype data and to conduct simulations of both microsatellite and single nucleotide polymorphism (SNP) data types to develop expectations and to compare Ne^ estimators.

    A study of the Ne-20(d,p)Ne-21 transfer reaction was performed using the Quadrupole Dipole Dipole Dipole (Q3D) magnetic spectrograph in Garching, Germany. The experiment probed excitation energies in Ne-21 ranging from 6.9 MeV to 8.5 MeV. The aim was to investigate the spectroscopic information of Ne-21 within the Gamow window of core helium burning in massive stars. Further information in this region will help reduce the uncertainties on the extrapolation down to Gamow window cross sections of the O-17(alpha,gamma)Ne-21 reaction. In low metallicity stars, this reaction has a direct impact on s-process abundances by determining the fate of O-16 as either a neutron poison or a neutron absorber. The experiment used a 22-MeV deuteron beam, with intensities varying from 0.5-1 mu A, and an implanted target of Ne-20 of 7 mu g/cm(2) in 40 mu g/cm(2) carbon foils. Sixteen Ne-21 peaks have been identified in the E-x = 6.9-8.5 MeV range, of which only thirteen peaks correspond to known states. Only the previously-known E-x = 7.960 MeV state was observed within the Gamow window.

    This map of the Vigo NE quadrangle, Lincoln County, Nevada records the distribution, stratigraphy, and structural relationships of Tertiary intracaldera lavas and tuffs in the southeastern part of the Kane Springs Wash caldera, extracaldera Tertiary and upper Paleozoic rocks, and late Cenozoic surficial deposits both within and outside the caldera. The alkaline to peralkaline Kane Springs Wash caldera is the youngest (14 Ma) of three chemically related metaluminous to peralkaline calderas (Boulder Canyon caldera, 15 Ma; Narrow Canyon caldera, 16 Ma) of the nested Kane Springs Wash caldera complex. The chemistry of this caldera complex became progressively more alkalic with time, in contrast to the older calc-alkalic calderas and caldera complexes to the north that migrated progressively southward in eastern Nevada. The increasingly peralkaline eruptions from the Kane Springs Wash caldera complex reached a climax that was simultaneous with the end of both rapid extension and magmatism in this part of the Basin and Range. Using the assumption that degree of tilting is related to the degree of extension, the rate of extension increased until the abrupt halt at about 14 Ma. Silicic volcanism terminated at the Kane Springs Wash caldera followed only by local sporadic basaltic eruptions that ended by about 8 Ma. The northern boundary of an east-west-trending amagmatic corridor appears in the Vigo NE quadrangle south of the Kane Springs Wash caldera.

Certains disent même avoir identifié le moteur du temps. Quant aux philosophes, ils ne cessent depuis plus de deux millénaires de soumettre le temps au questionnement : est-il une sorte d'entité primitive, originaire, qui ne dériverait que d'elle-même? Ou procéderait-il au contraire d'une ou plusieurs autres entités, plus fondamentales: la relation de cause à effet, par exemple?

    The booster neutrino experiment (MiniBooNE) searches for νμ→νe oscillations using the O(1GeV) neutrino beam produced by the booster synchrotron at the Fermi National Accelerator Laboratory). The booster delivers protons with 8 GeV kinetic energy (8.89GeV/c momentum) to a beryllium target, producing neutrinos from the decay of secondary particles in the beam line. We describe the Monte Carlo simulation methods used to estimate the flux of neutrinos from the beam line incident on the MiniBooNE detector for both polarities of the focusing horn. The simulation uses the Geant4 framework for propagating particles, accounting for electromagnetic processes and hadronic interactions in the beam line materials, as well as the decay of particles. The absolute double differential cross sections of pion and kaon production in the simulation have been tuned to match external measurements, as have the hadronic cross sections for nucleons and pions. The statistical precision of the flux predictions is enhanced through reweighting and resampling techniques. Systematic errors in the flux estimation have been determined by varying parameters within their uncertainties, accounting for correlations where appropriate.

    2009-04-01

    Northern Siberia may play a key role for the climate on the entire Earth. The classical Milankovitch Theory suggests that changes in summer insolation due to the Earth' orbital parameters caused build-up of snow and ice over the extensive continental masses at high northern latitudes. Various positive feedback mechanisms, like surface albedo and sequestration/release of atmospheric carbon dioxide in/from frozen, organic-rich soils, could then be responsible for the onset of global glaciations. More recently, high northern latitudes have also gained a lot of attention due to the potential of their soils and peats to release large amounts of methane and carbon dioxide. The Siberian ecosystems may turn into significant greenhouse gas sources as global warming continues and causes melting of permafrost and mineralisation of soil organic material that has been built up and stored over thousands of years. Quaternary scientists are therefore searching for long-term and continuous archives in order to reconstruct the Siberian climate and landscape history. A wide range of different analytical tools (e.g. different dating techniques, elemental composition, mineralogy, magnetic properties, grain size distribution, characterisation of organic matter and palynology) is used to infer palaeoclimatically and palaeoecologically relevant information. All of these methods have their advantages and their disadvantages. For instance, pollen analyses allow a high taxonomic differentiation, but variable pollination rates of different plant species, influx of long-distance transported pollen, and variable preservation of different pollen taxa have to be considered. Concerning the interpretation of pollen spectra in NE-Siberia, arboreal pollen, especially larch pollen, are traditionally considered to be ‘warm plant taxa', hence the occurrence of these pollen in archives is interpreted as reflecting warm interglacial or interstadial conditions. We have recently presented a multi

    In-situ ocean observing platforms provide power and information transmission capability to sensors. Ocean observing platforms can be mobile, such as ships, autonomous underwater vehicles, drifters and profilers, or fixed, such as buoys, moorings and cabled observatories. The process of integrating sensors on platforms can imply substantial engineering time and resources. Constraints range from stringent mechanical constraints to proprietary communication and control firmware. In NeXOS, the implementation of a PUCK plug and play capability is being done with applications to multiple sensors and platforms. This is complemented with a sensor web enablement that addresses the flow of information from sensor to user. Open standards are being tested in order to assess their costs and benefits in existing and future observing systems. Part of the testing implied open-source coding and hardware prototyping of specific control devices in particular for closed commercial platforms where firmware upgrading is not straightforward or possible without prior agreements or service fees. Some platform manufacturers such as European companies ALSEAMAR[1] and NKE Instruments [2] are currently upgrading their control and communication firmware as part of their activities in NeXOS. The sensor development companies Sensorlab[3] SMID[4] and TRIOS [5]upgraded their firmware with this plug and play functionality. Other industrial players in Europe and the US have been sent NeXOS sensors emulators to test the new protocol on their platforms. We are currently demonstrating that with little effort, it is also possible to have such middleware implemented on very low-cost compact computers such as the open Raspberry Pi[6], and have a full end-to-end interoperable communication path from sensor to user with sensor plug and play capability. The result is an increase in sensor integration cost-efficiency and the demonstration will be used to highlight the benefit to users and ocean observatory

    The MicroBooNE detector has recently completed its first year of neutrino beam data-taking in the Booster Neutrino Beam at Fermilab, having collected approximately half of its intended data ($3.4\\times10^{20}$ of $6.6\\times10^{20}$ protons on target). We present kinematic distributions of neutrino interactions observed from a small subset of this data (equivalent to $5\\times10^{19}$ protons on target), both as a first step towards a charged-current muon neutrino cross-section on argon, and as an exploration of the capabilities and operational challenges of large liquid argon time projection chambers as neutrino detectors. These distributions have been assessed using fully automated event selection and reconstruction.

    Understanding of the dynamics, population kinetics, and energy budget of a K-shell radiating Z pinch remains a challenging problem in high energy density plasma physics. Large ion kinetic energies have been reported for Ne pinches at ˜1 MA.footnotetextE. Kroupp, et al., PRL, 98, 115001 (2007), D. Osin, Ph.D. Thesis (2008). The present work examines the dynamics of this pinch with a 1D radial magnetohydrodynamic simulation code including collisional-radiative ionization dynamics and radiation transport. Synthetic spectra from the simulations can match the measured H-like satellite line profiles if the ion-electron equilibration rate is reduced by a factor of ˜10. In anticipation of further experiments, radially resolved synthetic spectra of the satellite lines will also be presented to analyze the plasma structure at stagnation.

    The multifractal character of the daily extreme temperatures in Catalonia (NE Spain) is analyzed by means of the multifractal detrended fluctuation analysis (MF-DFA) applied to 65 thermometric records covering years 1950–2004. Although no clear spatial patterns of the multifractal spectrum parameters appear, factor scores deduced from Principal Component analysis indicate some signs of spatial gradients. Additionally, the daily extreme temperature series are classified depending on their complex time behavior, through four multifractal parameters (Hurst exponent, Hölder exponent with maximum spectrum, spectrum asymmetry and spectrum width). As a synthesis of the three last parameters, a basic measure of complexity is proposed through a normalized Complexity Index. Its regional behavior is found to be free of geographical dependences. This index represents a new step towards the description of the daily extreme temperatures complexity.

It is doubtful, however, that ne bis in idem qualifies as a principle of law. It should be regarded, rather, as a rule of criminal procedure, traditionally based on the principle of res judicata. Giving the rule of ne bis in idem a transnational dimension therefore requires either transnationalising the principle of res judicata, or giving the rule of ne bis in idem a new foundation.The principle of res judicata principally serves the credibility of the justice system in a given jurisdiction by prohibiting several tribunals, all acting within the parameters of their jurisdiction, from contradicting each other’s interpretation of the same facts. For this reason, the principle of res judicata does not provide an adequate basis for a transnationalised rule of ne bis in idem.From a human rights perspective, multiple prosecutions against the same person for the same facts collides with protecting individuals against arbitrary judicial treatment. This is true whether the multiple prosecutions all take place in one country or in several different countries. The rule of ne bis in idem could therefore be regarded as a manifestation of the (new ‘principle of personal legal certainty’.

  10. α cluster structures in unbound states in 19Ne

    Full Text Available Cluster structures in 19Ne are studied by the microscopic and macroscopic cluster models. In the microscopic calculation, the coupled-channels problem of (3He+16O + (α+15O is solved, and the adiabatic energy surfaces, which are the series of the energy eigenvalues as a function of the He–O distance, are investigated. In the adiabatic energy curves, the several local minima are generated in the spatial region of the small core distance, where the neutron hole inside of the He or O nucleus is strongly coupled to the residual nuclei. The energy spectra, which are constructed from the strong coupling states, nicely reproduce the the low-lying energy levels in the 19Ne nucleus. In the macroscopic approach, the α + 15O potential is evaluated from the elastic scattering of the α + 15N system, and the resonant levels of the α + 15O system are calculated under the absorbing boundary condition. The potential model predicts the existence of the resonances above the α threshold, which has a weak-coupling scheme of the α particle and one hole inside of the 16O nucleus. The extended microscopic calculations of (3He+16O + (α+15O + (5He+14O are performed in order to see the coupling effect of the 5p-2h configuration, which corresponds to the shell model limit of the 5He + 14O cluster configuration. The extended calculation suggests that the 5He + 14O configuration plays an important role on the formation of the 3/2+ resonance at 0.5 MeV with respect to the α threshold.

    Human papillomavirus (HPV) infection of the lower genital tract is common and its effects are variable. The majority of infections are transient and the related pathology is self-resolving. Condyloma accuminatum is caused predominantly by HPV 6, 11 and can be managed with medical or surgical therapy. Vulvar intraepithelial neoplasia is a treatable precursor to vulvar cancer with 2 main forms: one related to HPV and the other to chronic vulvar inflammatory conditions. It may be treated medically, surgically, or potentially via the use of therapeutic HPV vaccines. Preventive utilization of a quadrivalent HPV vaccine has the potential to decrease HPV-related lower genital disease burden substantially.

    2017-10-01

    Background: The 17F(p ,γ )18Ne reaction is part of the astrophysical "hot CNO" cycles that are important in astrophysical environments like novas. Its thermal reaction rate is low owing to the relatively high energy of the resonances and therefore is dominated by direct, nonresonant capture in stellar environments at temperatures below 0.4 GK. Purpose: An experimental method is established to extract the proton strength to bound and unbound states in experiments with radioactive ion beams and to determine the parameters of direct and resonant capture in the 17F(p ,γ )18Ne reaction. Method: The 17F(d ,n )18Ne reaction is measured in inverse kinematics using a beam of the short-lived isotope 17F and a compact setup of neutron, proton, γ -ray, and heavy-ion detectors called resoneut. Results: The spectroscopic factors for the lowest l =0 proton resonances at Ec .m .=0.60 and 1.17 MeV are determined, yielding results consistent within 1.4 σ of previous proton elastic-scattering measurements. The asymptotic normalization coefficients of the bound 21+ and 22+ states in 18Ne are determined and the resulting direct-capture reaction rates are extracted. Conclusions: The direct-capture component of the 17F(p ,γ )18Ne reaction is determined for the first time from experimental data on 18Ne.

  18. Using ICD for structural analysis of clusters: a case study on NeAr clusters

    2014-10-01

    We present a method to utilize interatomic Coulombic decay (ICD) to retrieve information about the mean geometric structures of heteronuclear clusters. It is based on observation and modelling of competing ICD channels, which involve the same initial vacancy, but energetically different final states with vacancies in different components of the cluster. Using binary rare gas clusters of Ne and Ar as an example, we measure the relative intensity of ICD into (Ne+)2 and Ne+Ar+ final states with spectroscopically well separated ICD peaks. We compare in detail the experimental ratios of the Ne-Ne and Ne-Ar ICD contributions and their positions and widths to values calculated for a diverse set of possible structures. We conclude that NeAr clusters exhibit a core-shell structure with an argon core surrounded by complete neon shells and, possibly, further an incomplete shell of neon atoms for the experimental conditions investigated. Our analysis allows one to differentiate between clusters of similar size and stochiometric Ar content, but different internal structure. We find evidence for ICD of Ne 2s-1, producing Ar+ vacancies in the second coordination shell of the initial site.

  20. Search for Antineutrino Charged Current Coherent Pion Production at SciBooNE

    CERN Document Server

    Tanaka, Hide-Kazu

    2009-01-01

    The SciBooNE experiment (Fermilab) recently published results of a search for charged current coherent pion production in neutrino mode: muon neutrinos scattering on carbon. The results of this study are that no evidence for coherent pion production is observed, and SciBooNE set 90% confidence level upper limits on the cross section ratio of charged current coherent pion production to the total charged current cross section. Recently proposed new coherent pion models predict a production of charged current coherent pion events just below the SciBooNE's upper limit. Motivated by this, we performed a search for charged current coherent pion production using SciBooNE's collected antineutrino data since antineutrino data are expected to be more sensitive to look at coherent pion production than neutrino data. This paper describes preliminary results of a search for antineutrino charged current coherent pion production at the SciBooNE experiment.

  1. Estimation of the effective population size (Ne) and its application in the management of small populations

    DEFF Research Database (Denmark)

    Jimenez Mena, Belen

    2016-01-01

    Effective population size (Ne) is an important concept to understand the evolution of a population. In conservation, Ne is used to assess the threat status of a population, evaluate its genetic viability in the future and set conservation priorities. An accurate estimation of Ne is thus essential...... is that genetic drift is homogeneous throughout the genome. We explored the variability of Ne throughout the genome of the Danish Holstein cattle, using temporally-spaced samples of individuals genotyped with a 54K SNP chip. We found heterogeneity in Ne across the genome both between chromosomes and in genomic...... the population against threat status thresholds. When molecular markers are not available, populations can be managed using pedigree information. However, this is challenging to do so for group-living species since individuals and their parentage are difficult to determine. We adapted a pedigree-based method...

  2. First experimental evidence of 2He decay from 18Ne excited states

    Rapisarda, E; Cardella, G; De Napoli, M; Raciti, G; Sfienti, C

    2010-01-01

    Two-proton decay from 18Ne excited states has been studied by complete kinematical detection of the decay products. The 18Ne nucleus has been produced as a radioactive beam by 20Ne projectile fragmentation at 45 AMeV on a 9Be target, using the FRIBs in-flight facility of the LNS. The 18Ne at 33 AMeV incident energy has been excited via Coulomb excitation on a natPb target. The correlated 2p emission has been disentangled from the uncorrelated 2p emission using a high granularity particle detector setup allowing the reconstruction of momentum and angle correlations of the two emitted protons. The obtained results unambiguously show that the 6.15 MeV 18Ne state two-proton decay proceeds through 2He emission (31%) and democratic or virtual sequential decay (69%).

  3. The MiniBooNE detector technical design report

    I. Stancu et al.

    2003-04-18

    The MiniBooNE experiment [1] is motivated by the LSND observation, [2] which has been interpreted as {nu}{sub {mu}} {yields} {nu}{sub e} oscillations, and by the atmospheric neutrino deficit, [3,4,5] which may be ascribed to {nu}{sub {mu}} oscillations into another type of neutrino. MiniBooNE is a single-detector experiment designed to: obtain {approx} 1000 {nu}{sub {mu}} {yields} {nu}{sub e} events if the LSND signal is due to {nu}{sub {mu}} {yields} {nu}{sub e} oscillations, establishing the oscillation signal at the > 5{sigma} level as shown in Fig. 1.1; extend the search for {nu}{sub {mu}} {yields} {nu}{sub e} oscillations significantly beyond what has been studied previously if no signal is observed; search for {nu}{sub {mu}} disappearance to address the atmospheric neutrino deficit with a signal that is a suppression of the rate of {nu}{sub {mu}}C {yields} {mu}N events from the expected 600,000 per year; measure the oscillation parameters as shown in Fig. 1.2 if oscillations are observed; and test CP conservation in the lepton sector if oscillations are observed by running with separate {nu}{sub {mu}} and {bar {nu}}{sub {mu}} beams. The detector will consist of a spherical tank 6.1 m (20 feet) in radius, as shown in Fig. 1.3, that stands in a 45-foot diameter cylindrical vault. An inner tank structure at 5.75 m radius will support 1280 8-inch phototubes (10% coverage) pointed inward and optically isolated from the outer region of the tank. The tank will be filled with 807 t of mineral oil, resulting in a 445 t fiducial volume. The outer tank volume will serve as a veto shield for identifying particles both entering and leaving the detector with 240 phototubes mounted on the tank wall. Above the detector tank will be an electronics enclosure that houses the fast electronics and data acquisition system and a utilities enclosure that houses the plumbing, overflow tank, and calibration laser. The detector will be located {approx} 550 m from the Booster neutrino

  6. Pluvial Period over NE Brazil linked to Heinrich Stadial 4

    The precise timing and duration of Heinrich Stadials (HS) remains a topic of active debate. Here we present multiple NE Brazilian stalagmites known to grow during HS 4[i]. Using a combination of U/Th dating, confocal microscopy, and stable isotope analysis, we aim to provide additional age constraints on the Brazilian pluvial anomaly associated with HS 4. Stalagmite growth in this region is caused by increased rainfall due to a southerly displacement of the Intertropical Convergence Zone during HS Events. We focus on three stalagmites—TBV40, TBV63, and TBR14—collected from Toca da Boa Vista (TBV) and Toca da Barriguda (TBR) caves[ii], respectively. TBV40 and TBV63 each contain an aragonite phase U/Th dated from 40.02 to 39.57 ka B.P., followed by a calcitic phase U/Th dated from 39.27 to 38.74 ka B.P., within errors of ±0.1 ka. The switch from aragonite to calcite at approximately 39.57 ka B.P. is characterized by an abrupt 4‰ decrease in the δ18O record of TBV40. We infer that rainfall increased over NE Brazil at this time. TBR14 has a single calcite growth phase from 39.66 to 39.45 ka B.P., which correlates in part with the calcite phases of TBV40 and TBV 63. Stable isotope values for TBR14 are similar in range, trend, and absolute values to the correlative calcite portion of TBR40. Fluorescent banding was discovered in the calcitic portion of all three stalagmites using confocal laser scanning microscopy. If annual, band-counts may add additional constrains to the duration of the HS 4 growth phases. Adopting ice core band-counting methods, an average of 325±128 bands per sample and 17 small hiatuses were identified. The estimated duration of the calcitic HS 4 growth phases is therefore consistent with the U/Th dates. Growth phases may correlate in detail with other global records of HS 4, such as the Hulu Cave record[iii]from China, with the aragonitic portion correlating to the weak monsoon immediately following Chinese Interstadial 9 and the calcitic

    This paper is concerned with the microseismicity and seismotectonics of the eastern South Caspian Sea region, where the East Alborz mountains descend to meet the South Caspian Lowlands of NE Iran. To better understand the present-day tectonics and seismicity of this region, which includes the cities of Gorgan and Gonbad-e-Qabus (combined population 500 000), we installed a temporary local seismic network across the area for 6 months between 2009 and 2010. We analysed the seismicity and focal mechanisms together with data from the permanent networks of the Institute of Geophysics, University of Tehran (IGUT) and the International Institute of Earthquake Engineering and Seismology (IIEES), based in Tehran. Microseismicity is focused primarily on the Shahrud fault system, which bounds the east Alborz range to the south. Relatively few earthquakes are associated with the Khazar thrust fault, which bounds the north side of the range. A cluster of shallow microseismicity (Khazar fault (within the South Caspian Lowlands; SCL), an area typically thought to be non-deforming. This area coincides with the location of three relatively deep thrust earthquakes (Mw 5.3-5.5) which occurred in 1999, 2004 and 2005. Inversion of teleseismic body waveforms allows us to constrain the depth of these earthquakes at 26-29 km. Although significant sedimentation throughout the SCL obscures any expression of recent fault activity at the surface, focal mechanisms of well-located events from the shallow cluster of micro-seismicity show a significant component of left-lateral strike-slip motion (assuming slip occurs on NE-SW fault planes, typical of active faults in the region), as well as a small normal component. Inversion of traveltimes for well-located events in our network yields a velocity structure for the region, and a Moho depth of 41 km. The pattern of deep thrust and shallow normal seismicity could be explained by bending of the rigid South Caspian crust as it underthrusts the East

    Measurements on twin cores (RHSKS58 and RHSKS25) collected during the Rhosos cruise (2008) on the Rhone prodelta allowed to correlate specific sedimentary beds with historical floods of the Rhône River (1671AD-1986AD) using 137Cs and 206Pb/207Pb and large occurrence of freshwater ostracods of fluvial origin (Fanget, 2013 ; Fanget et al. 2013). Interpretation of short half-time radio-isotopes (210Pbxs), grain-size measurements with high-frequency sampling steps, together with the analysis of thin sections on indurated sediments and the measurement of major chemical elements using X-ray fluorescence (XRF) allowed to accurately characterize these flood beds. A few measurements of organic carbon and delta 13C have also been made. Major floods are characterized by grain-size variations that can either show a classical hyperpycnal sequence (with successive coarsening-up and fining-up units) or a classical turbidite sequence (fining-up trend). In any case, floods are characterized by an enrichment in quartz grains, a decrease in delta 13C values and an increase in organic matter content correlated with higher proportion of plant fragments. This testifies for a sudden continental input. Typical hyperpycnal sequences have been correlated with the change in daily discharge at the Rhône River mouth for floods between 1920 and 2000. These sequences are correlated with chemical elements that characterize a detrital input (high Ti/Ca, Si/Ca). The classical turbidites could result either from the distal transformation of hyperpycnal flows, from the rapid progradation of mouth bars, or more simply from the settling of turbulent clouds generated by prodelta slope failures during period of high sediment accumulation rates. Additional clay-rich beds could be correlated to the particle fall-out from hypopycnal plumes during low-magnitude floods. Fanget, A.-S. (2013).

    The geographical location of the State of Nuevo Leon, due to its physiographic features, has temperate and arid climate; undeveloped drainage, low precipitations, and high evapotranspiration rates, as well as rapid demographic growth. The hydrological data of the Pablillo basin, registered in the hydrometric station Cerro Prieto, showed an annual precipitation from 415 up to 1130 mm/a , the mean evaporation of 705 mm/a (up to 2460 mm/a in 1996). The maximum water storage of the Cerro Prieto reservoir is 395 millions m3 which corresponds to a water level of 295 meters. However, this level was reached only three times after the dam's construction. By the end of June 2006 the water level was at 276.2 m which corresponds to a water volume of about 127,806,300 m3 which is less than a third of maximum storage. Analysis of hydrological data showed sufficient misbalance between water recharge (by rain, river flow) and loss due to evaporation, filtration, extraction, discharge, etc. 160 gravity reading points, 400 onshore magnetic field readings as well as about 250 offshore magnetic points were carried out. The standard corrections as instrumental drift, latitude, elevation, IGRF, etc. were applied to obtained data. Data procession includes Fourier transformation, wavelength filters, upward continuation, vertical and horizontal derivates, etc. As a result a 2D geological-geophysical models and 3D maps were elaborated. The general trend of the magnetic field reduced to a pole is NW - SE on which background anomalies of northeast trend are obviously traced. The general trend of the gravity field received as a result of our works is the same. However, local magnetic and residual gravity anomalies have mosaic character and, being morphologically extended in a NE direction, grouped in chains of northwest trend. Potential data interpretation allows assuming a series of the superficial fractures focused in a NE direction, perpendicular (NW-SE) to the general deep fault. The

    National Energy Program-Phase II (NEPPII) was initiated to understand the geomechanical characteristic in Ilan geothermal area. In this study, we integrate well cores and logs (e.g. Nature Gamma-ray, Normal resistivity, Formation Micro Imager) which were acquired in HongChaiLin (HCL), Duck-Field (DF) and IC21 to determine the depth of fracture zone, in-situ stress state, the depth of basement and lithological characters. In addition, the subsurface in-situ stress state will be helpful to analyze the fault reactivation potential and slip tendency. By retrieved core from HCL well and the results of geophysical logging, indicated that the lithological character is slate (520m ~ 1500m) and the basement depth is around 520m. To get the minimum and maximum horizontal stress, several hydraulic fracturing tests were conducted in the interval of 750~765m on HCL well. The horizontal maximum and minimum stresses including the hydrostatic pressure are calculated as 15.39MPa and 13.57MPa, respectively. The vertical stress is decided by measuring the core density from 738m to 902m depth. The average core density is 2.71 g/cm3, and the vertical stress is 19.95 MPa (at 750m). From DF well, the basement depth is 468.9m. Besides, by analyzing the IC21 well logging data, we know the in-situ orientation of maximum horizontal stress is NE-SW. Using these parameters, the fault reactivation potential and slip tendency can be analyzed with 3DStress, Traptester software and demonstrated on model. On the other hand, we interpreted the horizons and faults from the nine seismic profiles including six N-S profiles, two W-E profiles and one NE-SW profile to construct the 3D subsurface structure model with GOCAD software. The result shows that Zhuosui fault and Kankou Formation are dip to north, but Hanxi fault and Xiaonanao fault are dip to south. In addition, there is a syncline-like structure on Nansuao Formation and the Chingshuihu member of the Lushan Formation. However, there is a conflict

    We present a blind search for doublet intergalactic metal absorption with a method dubbed `agnostic stacking'. Using a forward-modelling framework we combine this with direct detections in the literature to measure the overall metal population. We apply this novel approach to the search for Ne VIII absorption in a set of 26 high-quality COS spectra. We probe to an unprecedented low limit of log N>12.3 at 0.47≤z ≤1.34 over a pathlength Δz = 7.36. This method selects apparent absorption without requiring knowledge of its source. Stacking this mixed population dilutes doublet features in composite spectra in a deterministic manner, allowing us to measure the proportion corresponding to Ne VIII absorption. We stack potential Ne VIII absorption in two regimes: absorption too weak to be significant in direct line studies (12.3 13.7). We do not detect Ne VIII absorption in either regime. Combining our measurements with direct detections, we find that the Ne VIII population is reproduced with a power law column density distribution function with slope β = -1.86+0.18-0.26 and normalisation log f_{13.7} = -13.99+0.20-0.23, leading to an incidence rate of strong Ne VIII absorbers dn/dz =1.38+0.97-0.82. We infer a cosmic mass density for Ne VIII gas with 12.3 constituting 4% of the total baryonic mass.

  12. α +15 O cluster structures in 19Ne and the α resonant scattering

    2014-09-01

    Cluster structures are well known to appear in the excited states of light nuclear systems. A typical example is the α+16 O cluster structures in 20Ne, and the α+15 N structures are also deeply analyzed in 19F, which is one proton deficient system of 20Ne. However, the α+15 O structure, corresponding to the neutron deficient system of 20Ne, still remains unclear. In the present study, we investigate the α+15 O structure in 19Ne by employing a simple potential model. We assume the Wood-Saxon potential for the nuclear potential of α+15 O, and its parameter set is fixed by solving the α+15 N elastic scattering. From the nuclear potential determined from the α+15 N scattering problem, we calculate the energy levels in the 19Ne = α+15 O system by adding the Coulomb interaction to the α+15 N system. The absorbing boundary condition is imposed on the unbound states in α+15 O, and the resonant levels in 19Ne are identified. We have also calculated the excitation function of the resonant α+15 O elastic scattering under the same condition as the recent experiments. In the present report, we will show our prediction of the α+15 O rotational bands and the cross sections in the resonant α scattering. Moreover, we will also report the application of the microscopic cluster model to the 19Ne = α+15 O system.

    Metagenomics can reveal the vast majority of microbes that have been missed by traditional cultivation-based methods. Due to its extremely wide range of application areas, fast metagenome sequencing simulation systems with high fidelity are in great demand to facilitate the development and comparison of metagenomics analysis tools. We present here a customizable metagenome simulation system: NeSSM (Next-generation Sequencing Simulator for Metagenomics). Combining complete genomes currently available, a community composition table, and sequencing parameters, it can simulate metagenome sequencing better than existing systems. Sequencing error models based on the explicit distribution of errors at each base and sequencing coverage bias are incorporated in the simulation. In order to improve the fidelity of simulation, tools are provided by NeSSM to estimate the sequencing error models, sequencing coverage bias and the community composition directly from existing metagenome sequencing data. Currently, NeSSM supports single-end and pair-end sequencing for both 454 and Illumina platforms. In addition, a GPU (graphics processing units) version of NeSSM is also developed to accelerate the simulation. By comparing the simulated sequencing data from NeSSM with experimental metagenome sequencing data, we have demonstrated that NeSSM performs better in many aspects than existing popular metagenome simulators, such as MetaSim, GemSIM and Grinder. The GPU version of NeSSM is more than one-order of magnitude faster than MetaSim. NeSSM is a fast simulation system for high-throughput metagenome sequencing. It can be helpful to develop tools and evaluate strategies for metagenomics analysis and it's freely available for academic users at http://cbb.sjtu.edu.cn/~ccwei/pub/software/NeSSM.php.

    Full Text Available In Tertiary basins of NE Slovenia, Upper Oligocene volcanic activity occurred in a submarine environment that experienced contemporaneous clastic sedimentation. Pyroclastic deposits are essentially related to gas- and watersupported eruption-fed density currents. At Trobni Dol, the Lako Basin, an over 100 m thick deposit formed by a sigle sustained volcanic explosion that fed gas-supported pyroclastic flow. Diagnostic features are large matrixshard content, normal grading of pumice lapilli, collapsed pumice lapilli and the presence of charcoal. In the Smrekovec Volcanic Complex, several but only up to 5 m thick deposits related to eruption-fed gassupported pyroclastic flows occur. Deposits settled from water-supported eruption-fed density currents form fining- and thinning-upward sedimentary units which resemble the units of volcaniclastic turbidites. Pyroclastic deposits related to gas- and water-supported density currents occur in an up to 1000 m thick succession composed of coherent volcanics, autoclastic, pyroclastic, reworked volcaniclastic and mixed volcaniclastic-siliciclastic deposits that indicate a complex explosive and depositional history of the Smrekovec Volcanic Complex.

  16. Response matrices of NE213 scintillation detectors for neutrons

    1994-12-31

    Four NE213 detectors of different size have been calibrated at the accelerator facility of the PTB. The response functions were experimentally determined for 33 neutron energies between 1 MeV and 16 MeV and compared with Monte Carlo simulations using the NRESP7 code. The light output functions for recoil protons were found to be significantly different for all detectors even if they were of the same size. The neutron fluence determined on the basis of the response functions calculated with the corresponding light output functions agreed to better than {+-}2% with reference values if energy independent adjustment factors between 0.98 and 1.03 were applied. The response matrices required for the unfolding of neutron induced pulse height spectra were therefore calculated with the NRESP7 code taking into account the adjustment factors. Similarly, the response matrices for photons were calculated with the EGS4 code, but without any adjustment. Finally, the DIFBAS code was applied for the unfolding of pure neutron- and photon-induced pulse height spectra. The resulting spectral fluences are in reasonable agreement with the results obtained by time-of-flight measurements and by spectrometry with a Ge detector.

    The effects of an electron cloud (e-cloud) on beam dynamics are one of the major factors limiting performances of high intensity positron, proton, and ion storage rings. In the electron-positron collider DAΦNE, namely, a horizontal beam instability due to the electron-cloud effect has been identified as one of the main limitations on the maximum stored positron beam current and as a source of beam quality deterioration. During the last machine shutdown in order to mitigate such instability, special electrodes have been inserted in all dipole and wiggler magnets of the positron ring. It has been the first installation all over the world of this type since long metallic electrodes have been installed in all arcs of the collider positron ring and are currently used during the machine operation in collision. This has allowed a number of unprecedented measurements (e-cloud instabilities growth rate, transverse beam size variation, tune shifts along the bunch train) where the e-cloud contribution is clearly evidenced by turning the electrodes on and off. In this Letter we briefly describe a novel design of the electrodes, while the main focus is on experimental measurements. Here we report all results that clearly indicate the effectiveness of the electrodes for e-cloud suppression.

  20. Ne2 encodes protein(s) and the altered RuBisCO could be the proteomics leader of hybrid necrosis in wheat (Triticum aestivum L.).

    2017-06-01

    Wheat hybrid necrosis is caused by the interaction of two dominant complementary genes, Ne1 and Ne2, located on chromosome arms 5BL and 2BS, respectively. The sequences of Ne1 or Ne2 have not yet been identified. It is also not known whether Ne1 and Ne2 are structural or regulatory genes. Understanding the proteomic pathways may provide a knowledge base for protecting or maximizing the photosynthesis capacity of wheat. Using DIGE and MALDITOF- TOF MS, the flag leaf protein patterns of the two unique F14 near-isogenic line siblings (NILs), the necrotic ShunMai 12Ah (Ne1Ne1Ne2Ne2) and the normal ShunMai 12Af (Ne1Ne1ne2ne2) were compared. Due to the presence or absence of Ne2, (i) three protein spots were expressed or disappeared, (ii) seven RuBisCO-related proteins were altered significantly, and (iii) 21 photosynthesis/glucose related proteins were changed significantly. Three hypotheses were deduced, (i) Ne1 may also encode protein(s), (ii) genetic maladjustment of RuBisCO could lead to early leaf death, and (iii) interactions between nuclear genes and chloroplast genes could determine photosynthetic traits. Our hypothetical model presents the RuBisCO pathway of hybrid necrosis in wheat and explains how Ne1 and Ne2 interact at molecular level.

    In Sweden, Jurassic strata are restricted to Skåne and adjacent offshore areas. Jurassic sedimentary rocks predominantly comprise sandy to muddy siliciclastics, with subordinate coal beds andfew carbonate-rich beds. During Mesozoic times, block-faulting took place in the Sorgenfrei–Tornquist Zone, a tectonic zone which transects Skåne in a NW–SE direction. The Jurassic depositionalenvironments in Skåne were thus strongly influenced by uplift and downfaulting, and to some extent by volcanism. ...

    Single-electron capture in collisions of 9 keV x q Ne{sup 8+} and Ne{sup 7+} ions with He has been studied using cold-target recoil-ion momentum spectroscopy. With an improved apparatus a longitudinal momentum resolution of 0.07 au has been achieved. This momentum component is directly proportional to the difference in the binding energy of the active electron between the final and the initial state. For the first time state-resolved differential cross sections have been determined with respect to the main quantum number, subshell level and spin state of the captured electron. A comparison with recent theoretical results for energy levels in Be-like Ne is given. (author)

    Full Text Available While the reaction 22Ne(α,n25Mg is considered an important neutron source for the s process in massive stars, the competing 22Ne(α,γ26Mg reaction may be of considerable strength and could significantly suppress the neutron production. For a better understanding of this neutron source, the branching ratio of n and γ partial widths (Γn, Γγ and spectroscopic information such as energies and spins of 26Mg resonance states within the Gamow window (Eα = 400-1000 keV should be experimentally determined with improved accuracy. In the present work, we propose to use the 6Li(22Ne, 26Mgd α-transfer reaction to investigate those resonance parameters and have tested the feasibility of the experiment.

    The Cooper Ridge NE 7?-minute quadrangle is 18 miles southeast of Rock Springs, Wyo., on the east flank of the Rock Springs uplift. Upper Cretaceous rocks composing the Rock Springs Formation, Ericson Sandstone, Almond Formation, Lewis Shale, Fox Hills Sandstone, and Lance Formation, Paleocene rocks composing the Fort Union Formation, and Eocene rocks composing the Wasatch Formation are exposed and dip 5?-8? southeast. Outcrops are unfaulted and generally homoclinal, but a minor cross-trending fold, the Jackknife Spring anticline, plunges southeastward and interrupts the northeast strike of beds. Older rocks in the subsurface are faulted and folded, especially near the Brady oil and gas field. Coal beds are present in the Almond, Lance, and Fort Union Formations. Coal resources are estimated to be more than 762 million short tons in 16 beds more than 2.5 feet thick, under less than 3,000 ft of overburden. Nearly 166 million tons are under less than 200 ft of overburden and are recoverable by strip mining. Unknown quantities of oil and gas are present in the Cretaceous Rock Springs, Blair, and Dakota Formations, Jurassic sandstone (Entrada Sandstone of drillers), Jurassic(?) and Triassic(?) Nugget Sandstone, Permian Park City Formation, and Pennsylvanian and Permian Weber Sandstone at the Brady field, part of which is in the southeast corner of the quadrangle, and in the Dakota Sandstone at the Prenalta Corp.

    We have calculated the dielectronic recombination rate coefficients from Li-like Ne (Ne{sup 7+}) ions to Be-like Ne (Ne{sup 6+}) ions for selected excited states of Ne{sup 6+} ions. A collisional-radiative model (CRM) for Ne{sup 6+} ions is constructed to calculate the population density of each excited state in non-equilibrium ionization plasmas, including recombining processes. NeVII spectral line intensities and the radiative power loss are calculated with the CRM. A density effect caused by collisional excitation from the metastable state 2s2p {sup 3}P is found at an electron density of 10{sup 5} - 10{sup 17} cm{sup -3}. The collisional excitations between excited states become important at high electron temperature T{sub e} > or approx. 100 eV. (author)

    The Muon Range Detector (MRD) is one of three subsystems comprising the SciBooNE detector currently running in the Booster Neutrino Beamline at Fermilab. The MRD was constructed from recycled plastic scintillator panels and photomultiplier tubes between June 2006 and March 2007. This paper describes the selection, testing, and characterization of the photomultipliers, the testing of the completed counters, the assembly of the MRD itself, and its deployment in the SciBooNE detector enclosure and subsequent operation.

    Cellular influx of {sup 24}Na was measured in isolated rabbit aorta during stimulation with 10 {mu}M norepinephrine (NE) or depolarization with 80 mM K solution, using a pulse-labeling, cold-wash technique. NE caused a two- to threefold increase in Na influx; a smaller but significant increase was also observed in depolarized tissues. Basal and Ne-induced fluxes at 1 min were significantly increased by a 20-min preincubation in a Ca-free solution containing 2 mM EGTA; elevation of (Mg) in this solution reduced these effects. The high K-induced influx was prevented by a combination of low Ca (30 {mu}m) and elevated Mg (10 mM). The Ca agonist, BAY-K 8644, increased {sup 24}Na influx. The Ca antagonist, diltiazem, inhibited the depolarization-stimulated {sup 24}Na influx in a concentration-dependent manner, but was less effective in blocking the response to NE. Extension of the preincubation in NE plus Ca-free medium from 30 s to 15 min decreased the influx response and contraction. After exposure to NE in Ca-free solution, {sup 24}Na influx remained elevated 10 min after washing out NE in the continued absence of Ca. A second exposure to NE at that time did not increase influx. The authors propose that a component of {sup 24}Na influx during excitation depends directly on a rise in intracellular (Ca). The role of an indirect effect of (Ca) on metabolic H{sup +} production with subsequent stimulation of the Na{sup +}-H{sup +} exchange may also be a factor.

    2003-10-01

    Full Text Available In Sweden, Jurassic strata are restricted to Skåne and adjacent offshore areas. Jurassic sedimentary rocks predominantly comprise sandy to muddy siliciclastics, with subordinate coal beds andfew carbonate-rich beds. During Mesozoic times, block-faulting took place in the Sorgenfrei–Tornquist Zone, a tectonic zone which transects Skåne in a NW–SE direction. The Jurassic depositionalenvironments in Skåne were thus strongly influenced by uplift and downfaulting, and to some extent by volcanism. Consequently, the sedimentary record reveals evidence of numerous transgressions, regressions and breaks in sedimentation. Relative sea-level changes played a significant role in controlling the facies distribution, as deposition mainly took place in coastal plain to shallow shelf environments.The alluvial deposits in Skåne include floodplain palaeosols, autochthonous coals, overbank sandstones, and stream channel pebbly sandstones. Restricted marine strata comprise intertidalheteroliths with mixed freshwater and marine trace fossil assemblages, and intertidal delta distributary channel sandstones. Shallow marine sediments encompass subtidal and shoreface sandstoneswith herringbone structures, and bioturbated mudstones with tempestite sandstones. Offshore deposits typically comprise extensively bioturbated muddy sandstones.Floral remains, palaeopedology, clay mineralogy and arenite maturity indicate a warm and humid climate in Skåne throughout the Jurassic, possibly with slightly increasing aridity towards the end of the period. Most Jurassic strata in Skåne have been subjected to mild burial diagenesis, and the petroleum generative window has rarely been reached.

  12. Implications of an updated ultraviolet background for the ionization mechanisms of intervening Ne VIII absorbers

    Ne VIII absorbers seen in QSO spectra are useful tracers of warm ionized gas, when collisional ionization is the dominant ionization process. While photoionization by the ultraviolet background (UVB) is a viable option, it tends to predict large line-of-sight thickness for the absorbing gas. Here, we study the implications of the recently updated UVB at low z to understand the ionization mechanisms of intervening Ne VIII absorbers. With the updated UVB, one typically needs higher density and metallicity to reproduce the observed ionic column densities under photoionization. Both reduce the inferred line-of-sight thicknesses of the absorbers. We find a critical density of ≥5 × 10-5 cm-3 above which the observed N({Ne VIII})/N({O VI}) can be reproduced by pure collisional processes. If the gas is of near solar metallicity (as measured for the low ions) then the cooling time-scales will be small (inferred low ion metallicity is near solar or supersolar. If we assume the Ne VIII phase to have similar metallicities then photoionization can reproduce the observed N({Ne VIII})/N({O VI}) without the line-of-sight thickness being unreasonably large and avoids cooling issues related to the collisional ionization at these metallicities. However, the indication of broad Lyα absorption in a couple of systems, if true, suggests that the Ne VIII phase is distinct from the low ion phase having much lower metallicity.

  13. Could LC-NE-Dependent Adjustment of Neural Gain Drive Functional Brain Network Reorganization?

    Directory of Open Access Journals (Sweden)

    Carole Guedj

    2017-01-01

    Full Text Available The locus coeruleus-norepinephrine (LC-NE system is thought to act at synaptic, cellular, microcircuit, and network levels to facilitate cognitive functions through at least two different processes, not mutually exclusive. Accordingly, as a reset signal, the LC-NE system could trigger brain network reorganizations in response to salient information in the environment and/or adjust the neural gain within its target regions to optimize behavioral responses. Here, we provide evidence of the co-occurrence of these two mechanisms at the whole-brain level, in resting-state conditions following a pharmacological stimulation of the LC-NE system. We propose that these two mechanisms are interdependent such that the LC-NE-dependent adjustment of the neural gain inferred from the clustering coefficient could drive functional brain network reorganizations through coherence in the gamma rhythm. Via the temporal dynamic of gamma-range band-limited power, the release of NE could adjust the neural gain, promoting interactions only within the neuronal populations whose amplitude envelopes are correlated, thus making it possible to reorganize neuronal ensembles, functional networks, and ultimately, behavioral responses. Thus, our proposal offers a unified framework integrating the putative influence of the LC-NE system on both local- and long-range adjustments of brain dynamics underlying behavioral flexibility.

    Four potential energy surfaces are of current interest for the Ne-CO interaction. Two are high-level fully ab initio surfaces obtained a decade ago using symmetry-adapted perturbation theory and supermolecule coupled-cluster methods. The other two are very recent exchange-Coulomb (XC) model potential energy surfaces constructed by using ab initio Heitler-London interaction energies and literature long range dispersion and induction energies, followed by the determination of a small number of adjustable parameters to reproduce a selected subset of pure rotational transition frequencies for the (20)Ne-(12)C(16)O van der Waals cluster. Testing of the four potential energy surfaces against a wide range of available experimental microwave, millimeter-wave, and mid-infrared Ne-CO transition frequencies indicated that the XC potential energy surfaces gave results that were generally far superior to the earlier fully ab initio surfaces. In this paper, two XC model surfaces and the two fully ab initio surfaces are tested for their abilities to reproduce experiment for a wide range of nonspectroscopic Ne-CO gas mixture properties. The properties considered here are relative integral cross sections and the angle dependence of rotational state-to-state differential cross sections, rotational relaxation rate constants for CO(v=2) in Ne-CO mixtures at T=296 K, pressure broadening of two pure rotational lines and of the rovibrational lines in the CO fundamental and first overtone transitions at 300 K, and the temperature and, where appropriate, mole fraction dependencies of the interaction second virial coefficient, the binary diffusion coefficient, the interaction viscosity, the mixture shear viscosity and thermal conductivity coefficients, and the thermal diffusion factor. The XC model potential energy surfaces give results that lie within or very nearly within the experimental uncertainties for all properties considered, while the coupled-cluster ab initio surface gives

    2012-01-01

    This dissertation reports the antineutrino-nucleus neutral current elastic scattering cross section on CH2 measured by the MiniBooNE experiment located in Batavia, IL. The data set consists of 60,605 events passing the selection cuts corresponding to 10.1×1020 POT, which represents the world’s largest sample of antineutrino neutral current elastic scattering events. The final sample is more than one order of magnitude lager that the previous antineutrino NCE scattering cross section measurement reported by the BNL E734 experiment. The measurement presented in this dissertation also spans a wider range in Q2, including the low-Q2 regime where the cross section rollover is clearly visible. A X2-based minimization was performed to determine the best value of the axial mass, MA and the Pauli blocking scaling function, that matches the antineutrino NCE scattering data. However, the best fit values of MA=1.29 GeV and K=1.026 still give a relatively poor X2, which suggests that the underlying nuclear model (based largely on the relativistic Fermi gas model) may not be an accurate representation for this particular interaction. Additionally, we present a measurement of the antineutrino/neutrino-nucleus NCE scattering cross section ratio. The neutrino mode NCE sample used in this study, corresponding to 6.4 × 1020 POT, is also the world’s largest sample (also by an order of magnitude). We have demonstrated that the ratio measurement is robust, as most of the correlated errors cancel, as expected. Furthermore, this ratio also proves to be rather insensitive to variations in the axial mass and the Pauli blocking parameter. This is the first time that this ratio has been experimentally reported. We believe this measurement will aid the theoretical physics community to test various model predictions of neutrino-nucleon/nucleus interactions.

    Full Text Available Cet article analyse les limites du naturalisme social que Laurence Kaufman et Laurent Cordonier proposent d’adopter dans cette même revue, en critiquant leur plaidoyer pour l’intégration des savoirs des sciences cognitives et des sciences humaines et sociales. Cette critique repose sur la réfutation de trois idées soutenues par les auteurs : 1 la description scientifique des mécanismes cognitifs élémentaires fournit une explication causale des conduites sociales qui doit se substituer à celles des sciences humaines et sociales ; 2 le recours au naturalisme permet de falsifier les préconceptions que ces dernières continuent à entretenir ; 3 le programme de naturalisation de l’esprit n’implique aucune forme de réductionnisme. Cette triple critique permet de rejeter leur appel en faveur d’un modèle intégré de la conduite humaine, en avançant un constat : dans la mesure où on ne sait pas comment combler le hiatus qui sépare les descriptions détaillées du cerveau au travail de l’explication des conduites des individus et de la manière dont ils en assurent la coordination dans le temps même où ils agissent en commun, les sciences humaines et sociales ont peu de choses à aller glaner du côté des sciences cognitives pour améliorer la manière dont elles analysent l’action. C’est que le travail de celles-ci se situe soit au niveau infra-humain du fonctionnement moléculaire, soit au niveau supra-humain de l’évolution ; et que seules les sciences humaines et sociales placent leurs analyses à un niveau simplement humain, en faisant des individus tels qu’ils vivent ensemble la mesure de toutes les choses qui les concernent.

    A study of the performance of the NeQuick model and the Klobuchar model for GNSS single frequency range delay correction on a global scale was done using data for moderate solar activity. In this study NeQuick was used in the way intended for Galileo. This study is to assess the performance of the two models at each ionospheric geographic region during moderate solar activity as previously published studies were concentrated only on high solar activity. The results obtained showed that NeQuick outperformed Klobuchar for the whole year at the three geographical regions of the ionosphere. In terms of monthly root mean square of mismodeling, NeQuick outperformed Klobuchar by 15 TECU or more at low-latitudes, 5 TEC or more at mid-latitudes, and 1 TECU or more at high-latitudes. Also, a study on how the data ingestion technique already developed for NeQuick could be expanded in order to reduce the deviation of NeQuick TEC prediction from observation for a particular day based on the information from the previous day was done. Instead of obtaining a regularly spaced Az grid from monitoring stations spread across the region of interest, we obtained hourly Az coefficients from hourly Az from designated monitoring stations. The obtained hourly Az coefficients were then used to drive NeQuick for the next day at the test stations. The results obtained, in terms of daily RMS of mismodeling, showed a daily maximum improvement of 26.0% at low-latitudes, 54.9% at mid-latitudes, and 41.3% at high-latitudes.

    Full Text Available This work evaluated the physicochemical composition of 171 red Brazilian wines from the 2006 vintage, which were represented by 21 varietals. These wines were produced by 58 Brazilian wineries in different regions of the country, with latitudes varying from 9º to 31º South. Physicochemical wine analysis was performed in the same year and discrimination in the viticultural regions, varietal wines, and wineries was performed by means of the principal component analysis (PCA. The main results show that wines from São Joaquim had higher values of A420, A520, A620, color intensity, total phenolic compounds, anthocyanins, and dry extracts, while those from Toledo had lower values of these variables; those from Vale do São Francisco had higher values of potassium, pH, density, and volatile acidity; from Serra do Nordeste A, they had higher titratable acidity; and from Planalto Superior B, higher hue. Regarding the varietal wines, PCA mainly discriminated the wines produced from the varieties Ancellotta, Teroldego, Egiodola, Refosco, Marselan, Cabernet Sauvignon, Pinotage, Pinot Noir, Malbec, Arinarnoa, Barbera, and Alfrocheiro. In relation to wineries, twenty two of them were discriminated by their higher values of some variables, i.e., three were characterized by color intensity; three by hue; eight by alcohol content; six by potassium, dry extract, density, and pH; and two by titratablel acidity.O trabalho avaliou a composição físico-química de 171 vinhos tintos brasileiros elaborados na safra de 2006, representados por 21 varietais.

  1. Neutrino-nucleus neutral current elastic interactions measurement in MiniBooNE

    2009-12-01

    The MiniBooNE experiment at the Fermi National Accelerator Laboratory (Fermilab) was designed to search for vμ → ve neutrino oscillations at Δm2 ~ 1 eV2 using an intense neutrino flux with an average energy Ev ~ 700 MeV. From 2002 to 2009 MiniBooNE has accumulated more than 1.0 x 1021 protons on target (POT) in both neutrino and antineutrino modes. MiniBooNE provides a perfect platform for detailed measurements of exclusive and semiinclusive neutrino cross-sections, for which MiniBooNE has the largest samples of events up to date, such as neutral current elastic (NCE), neutral current π0, charged current quasi-elastic (CCQE), charged current π+, and other channels. These measured cross-sections, in turn, allow to improve the knowledge of nucleon structure. This thesis is devoted to the study of NCE interactions. Neutrino-nucleus neutral current elastic scattering (vN → vN) accounts for about 18% of all neutrino interactions in MiniBooNE. Using a high-statistics, high purity sample of NCE interactions in MiniBooNE, the flux-averaged NCE differential cross-section has been measured and is being reported here. Further study of the NCE cross-section allowed for probing the structure of nuclei. The main interest in the NCE cross-section is that it may be sensitive to the strange quark contribution to the nucleon spin, Δs, this however requires a separation of NCE proton (vp → vp) from NCE neutron (vn → vn) events, which in general is a challenging task. MiniBooNE uses a Cherenkov detector, which imposes restrictions on the measured nucleon kinematic variables, mainly due to the impossibility to reconstruct the nucleon direction below the Cherenkov threshold. However, at kinetic energies above this threshold MiniBooNE is able to identify NCE proton events that do not experience final state interactions (FSI). These events were used for the Δs measurement.

    The Grote Brogel fault (GBF) is a WNW-ESE striking normal fault that is part of the western border fault system of the Roer Valley Graben in NE Belgium. It is one of three faults branching NW-ward from the main border fault (Geleen fault) near Bree, but its orientation diverges 22° from the general NW-SE orientation of the graben, causing a wide left step. Unlike the Geleen fault, the surface expression of the GBF has not been investigated in detail so far. We studied the Quaternary activity of the GBF and its effects on the local hydrology based on a high-resolution LiDAR digital terrain model (DTM), and geophysical and geological surveying at two sites, combining Electrical Resistivity Tomography (ERT), Cone Penetration Tests (CPTs) and boreholes. The GBF defines the northern edge of the Campine Plateau, an elevated area covered by the late Early to Middle Pleistocene Main Terrace of the Meuse River. Cumulative vertical offset since deposition of this terrace has resulted in a distinct 10-km-long fault scarp, the height of which decreases from 11 m near Bree in the east to less than 5 m near Grote Brogel in the west. The along-strike evolution of offset suggests that the GBF does not define an individual rupture segment, but is likely contiguous with the Geleen fault. DTM analysis indicates that scarps are only preserved in a few isolated places, and that the surface trace is rather complex, consisting of a series of short, relatively straight sections with strikes varying between 255° and 310°, arranged in a generally left-stepping pattern. At both investigated sites, ERT profiles clearly demonstrate the presence of fault splays in the shallow subsurface (< 50 m) underneath the identified scarps evidenced by a sudden increase in depth and thickness of a high-resistivity unit on top of a lower-resistivity unit. Boreholes and CPTs allow correlating the high-resistivity unit with the medium to coarse gravel-bearing sands of the Meuse Group, and the lower

    Full Text Available The global ionospheric maps (GIMs, generated by Jet Propulsion Laboratory (JPL and Center for Orbit Determination in Europe (CODE during a period over 13 years, have been adopted as the primary source of data to provide global ionospheric correction for possible single frequency positioning applications. The investigation aims to assess the performance of new NeQuick model, NeQuick 2, in predicting global total electron content (TEC through ingesting the GIMs data from the previous day(s. The results show good performance of the GIMs-driven-NeQuick model with average 86% of vertical TEC error less than 10 TECU, when the global daily effective ionization indices (Az versus modified dip latitude (MODIP are constructed as a second order polynomial. The performance of GIMs-driven-NeQuick model presents variability with solar activity and behaves better during low solar activity years. The accuracy of TEC prediction can be improved further through performing a four-coefficient function expression of Az versus MODIP. As more measurements from earlier days are involved in the Az optimization procedure, the accuracy may decrease. The results also reveal that more efforts are needed to improve the NeQuick 2 model capabilities to represent the ionosphere in the equatorial and high-latitude regions.

    The $^{22}$Ne(p,$\\gamma$)$^{23}$Na reaction takes part in the neon-sodium cycle of hydrogen burning. This cycle affects the synthesis of the elements between $^{20}$Ne and $^{27}$Al in asymptotic giant branch stars and novae. The $^{22}$Ne(p,$\\gamma$)$^{23}$Na reaction rate is very uncertain because of a large number of unobserved resonances lying in the Gamow window. At proton energies below 400\\,keV, only upper limits exist in the literature for the resonance strengths. Previous reaction rate evaluations differ by large factors.

    Performances of Galileo NeQuick model are analyzed over the continental and oceanic regions for the whole year of 2013. The three broadcast coefficients of NeQuick are computed from 23 globally distributed tracking stations of the International GNSS Services (IGS), by ingesting the Global Positioning System (GPS) derived ionospheric total electron content (TEC) into the original NeQuick 2 model. In continental regions, the ionospheric TEC derived from 34 IGS stations are used as references for the comparison. In oceanic regions, where the IGS stations are sparse,high-quality vertical TEC sources provided by JASON 1 and 2 altimeters are used as references. GPS broadcast Klobuchar, the original and broadcast NeQuick can mitigate the ionospheric delay by 56.8%, 63.3% and 72.4%, respectively, when compared to GPS TEC. The three models can correct 51.1%, 61.2 % and 68.6% of the ionospheric delay when compared to JASON TEC. Galileo NeQuick model outperforms Klobuchar by 15.6% and 17.5% over the continental and oceanic regions, respectively, for the test period.

  6. Sembène Ousmane's Xala: The Use of Film and Novel as Revolutionary Weapon

    Directory of Open Access Journals (Sweden)

    Kenneth Harrow

    1980-01-01

    Full Text Available Sembène Ousmane's Xala was written as a novel and made into a film in 1974. It is a biting attack upon the newly risen bourgeois class that has ascended to power and wealth in Senegal since independence. The ideological framework of Xala rests upon Marxist assumptions adapted to and modified by the circumstances in Africa. The distinctively Senegalese features which mark Sembène's portrayal include Muslim and traditional religious beliefs which form the basis of the class oppression and the sexism depicted in Xala . They also supply the title to the work since xala means impotency in Wolof, and it is described with great humor by Sembène, as the result of a marabout's curse. Sembène's treatment of the theme of class oppression focuses upon the great disparities that exist between the wealthy, elite classes and the impoverished masses, especially the beggars and cripples who live on the streets of Dakar. By focusing upon the issue of acculturation in the film, and by emphasizing the importance of imagery related to sight and the act of seeing, Sembène effectively overcomes the deficiencies of the novel in creating the film version of Xala .

    1976-09-01

    A potential energy surface for the Ne--H/sub 2//sup +/ reaction has been obtained in the LCAO--MO--SCF approximation. Analysis of the surface indicates that the reaction Ne+H/sub 2//sup +/..-->..NeH/sup +/+H should proceed with an endoergicity of 12 kcal/mole, in agreement with the experimental results of Chupka and Russell. Several procedures for parameterizing a diatomics-in-molecules (DIM) representation of the NeH/sub 2//sup +/ surface are considered. The results show that an accurate representation of the SCF surface can be obtained from the DIM model using a minimum of diatomic and triatomic data. (AIP)

    2016-01-01

    Full Text Available The acoustic neutrino detection technique is a promising approach for future large-scale detectors with the aim of measuring the small expected flux of cosmogenic neutrinos at energies exceeding 1 EeV. It suggests itself to investigate this technique in the context of underwater Cherenkov neutrino telescopes, in particular KM3NeT, because acoustic sensors are present by design to allow for the calibration of the positions of the optical sensors. For the future, the KM3NeT detector in the Mediterranean Sea will provide an ideal infrastructure for a dedicated array of acoustic sensors. In this presentation results from the acoustic array AMADEUS of the ANTARES detector will be discussed with respect to the potential and implications for acoustic neutrino detection with KM3NeT and beyond.

    SciBooNE, located in the Booster Neutrino Beam at Fermilab, collected data from June 2007 to August 2008 to accurately measure muon neutrino and anti-neutrino cross sections on carbon below 1 GeV neutrino energy. SciBooNE is studying charged current interactions. Among them, neutral pion production interactions will be the focus of this poster. The experimental signature of neutrino-induced neutral pion production is constituted by two electromagnetic cascades initiated by the conversion of the {pi}{sup 0} decay photons, with an additional muon in the final state for CC processes. In this poster, I will present how we reconstruct and select charged-current muon neutrino interactions producing {pi}{sup 0}'s in SciBooNE.

    Full Text Available The KM3NeT European project aims at constructing a km3 underwater neutrino telescope in the depths of the Mediterranean Sea. The first phase that is under construction will comprise eight tower-like detection structures (KM3NeT-Italia, which will form the internal core of a km3-scale detector. The detection element of KM3NeT-Italia, the optical module, is made of a 13-inch pressure-resistant glass-vessel that contains a single 10-inch photomultiplier and the relative electronics. The design of the whole optical module, the main results obtained from the massive photomultipliers measurements, and the foremost phases of the mass production procedure performed at the production site of Catania are also presented.

    1999-09-01

    Vector momentum distributions of Ne{sup n+} (n=1,2,3) ions created by 30 fs, {approx}1 PW/cm{sup 2} laser pulses at 795 nm have been measured using Recoil-Ion Momentum Spectroscopy. Distinct maxima along the light polarization axis are observed at 4.0 a.u. and 7.5 a.u. for Ne{sup 2+} and Ne{sup 3+} production, respectively. Hence, mechanisms based on an instantaneous release of two (or more) electrons can be ruled out as dominant contribution to non-sequential strong-field multiple ionization. The positions of the maxima are in accord with kinematical constraints set by the classical ''rescattering model''. (orig.)

    Eighteen crude oils and seven source rock samples from the Mesopotamian foredeep, NE Syria, and from the NE Palmyrides in the centre of the country have been characterized by geochemical techniques. The presence of two oil families ('A' and 'B') generated by different source rock types of different ages has been established on the basis of biomarker and carbon isotopic analyses. The data indicates that Groups A and B oils were generated by marine clastic and marine carbonate-evaporitic source rocks, respectively. Group A oils, occurring in Middle Triassic, Middle Jurassic and Upper Cretaceous reservoir rocks in the NE Palmyride area, are geochemically similar to extracts from the Lower Triassic Amanus Shale Formation. Group B oils, which are present in Middle Triassic, Middle Jurassic and Upper Cretaceous reservoirs in the Mesopotamian foredeep, are geochemically similar to extracts of the Middle Triassic Kurra Chine Dolomite and Upper Cretaceous Shiranish Formations.

    Using the multireference configuration interaction method with a Davidson correction and a large orbital basis set (aug-cc-pVQZ), we obtain an energy grid that includes 32 038 points for the construction of a new analytical potential energy surface (APES) for the Ne + H(2)(+) → NeH(+) + H reaction. The APES is represented as a many-body expansion containing 142 parameters, which are fitted from 31 000 ab initio energies using an adaptive nonlinear least-squares algorithm. The geometric characteristics of the reported APES and the one presented here are also compared. On the basis of the APES we obtained, reaction cross sections are computed by means of quasi-classical trajectory (QCT) calculations and compared with the experimental and theoretical data in the literature.

    The article deals with the detection efficiency of UV-photon detectors consisting of Thick Gas Electron Multipliers (THGEM) coated with CsI photocathode, operated in atmospheric Ne/CH4 and Ne/CF4 mixtures. We report on the photoelectron extraction efficiency from the photocathode into these gas mixtures, and on the photoelectron collection efficiency into the THGEM holes. Full collection efficiency was reached in all gases investigated, in some cases at relatively low multiplication. High total detector gains for UV photons, in excess of 10^5, were reached at relatively low operation voltages with a single THGEM element. We discuss the photon detection efficiency in the context of possible application to RICH.

  18. MicroBooNE and the Road to Large Liquid Argon Neutrino Detectors

    Science.gov (United States)

    Karagiorgi, G.

    Liquid Argon Time Projection Chambers (LArTPC's) provide a promising technology for multi-kiloton scale detectors aiming to address-among other pressing particle physics questions-the possibility of short and long baseline electron neutrino and antineutrino appearance. MicroBooNE, a 170 ton LArTPC under construction, is the next necessary step in a phased R&D effort toward construction and stable operation of larger-scale LArTPC's. This development effort also leans heavily on the ArgoNeuT and LAr1 LArTPC R&D experiments at Fermilab. In addition to advancing the LArTPC technology, these projects also provide unique physics opportunities. For example, Micro-BooNE will be located in the Booster Neutrino Beamline at Fermilab, at ∼470 m from neutrino production. Thus, in addition to measuring a suite of low energy neutrino cross sections on argon, MicroBooNE will investigate the anomalous low energy excess seen by the MiniBooNE experiment. Furthermore, the neutrino beam energy and relatively short baseline provide MicroBooNE with sensitivity to high-∼m2 neutrino oscillations. These proceedings summarize the role of the MicroBooNE detector in the US LArTPC R&D program, present its physics reach, and briefly discuss the physics potential of a dedicated near-future neutrino oscillation program at the Booster Neutrino Beamline, as a way to maximize the physics output of the Fermilab LArTPC R&D projects.

    The possible existence of light sterile neutrinos in Nature is motivated, and the prospects to extend sterile neutrino searches beyond current limits is substantiated, using the MiniBooNE neutrino beam and detector at Fermilab. We report on the neutrino flux predictions for the MiniBooNE experiment, on the characterization of the charged-current, quasi-elastic interactions of muon neutrinos ({nu}{sub {mu}}n {yields} {mu}{sup -}p) observed, and on the experiment's sensitivity to sterile neutrinos via muon neutrino disappearance.

    2009-12-01

    The measurement of absolute neutrino and anti-neutrino cross-sections, the observation of a 'low energy anomaly' in the neutrino sector, the constraints placed on the LSND effect by a non-observation of neutrino oscillations, the search for neutrino and anti-neutrino appearance, and for the possible existence of new heavy particles makes MiniBooNE a major contributor to the current view of the Universe. This paper addresses specific model constraints set by the MiniBooNE data, and explores expectations for further remaining analysis of the data.

    Alum has been in use since long as an adjuvant for vaccines. However, its use as a vaccine adjuvant offers limitation in supporting cell mediated response. Therefore, a new plant based product RLJ-NE-299A from Picrorhiza kurroa reported for its immunostimulatory activity, has been explored for its potential as an alternative adjuvant. In order to compare the adjuvant activity with alum, antigen-specific immune responses were evaluated following immunization with a formulation containing hepatitis B surface antigen (HBsAg) adjuvanted with RLJ-NE-299A and alum in mice. The adjuvant RLJ-NE-299A up-regulated remarkably the expression of Th1 cytokines IL-2, IL-12, IFN-gamma, TNF alpha and Th2 cytokine IL-4 in lymph node cell cultures after 2 weeks of primary immunization with HBsAg. Further, the levels of both immunoglobulins IgG2a (Th1) and IgG1 (Th2) subtypes increased profoundly in blood sera of mice immunized with HBsAg/RLJ-NE-299A. The results indicated that RLJ-NE-299A has strong potential to increase both cell mediated and humoral immune responses and is capable of sustaining the total antigen-specific antibody response. Besides, the RLJ-NE-299A provides a signal to gear up both CD4 helper cells (Th1 and Th2) and CD8 cells populations, which may have important implications for vaccination against hepatitis B virus. Variable doses of RLJ-NE-299A (0.312-40 microg) containing vaccine antigen (HBsAg) were well tolerated with optimum T cell response at 2.5 microg/ml. Not only this, the adjuvant was also able to induce cellular immune responses to HBsAg as evidenced by Th1 and Th2 cytokines upregulation, which enabled mice to overcome the unresponsiveness to antigen HBsAg encountered with alum-adjuvanted vaccine in otherwise non-responding mice population. The study presents evidence that the HPLC standardized fraction RLJ-NE-299A, is an adjuvant of choice over alum in improving and maintaining the improved immune status against HBsAg, and may also prove useful

    The photomultiplier signals above a defined threshold (hits) are the main data collected from the KM3NeT neutrino telescope. The neutrino and muon events will be reconstructed from these signals. However, in the deep sea the dominant source of hits are the decays of {sup 40}K isotope and marine fauna bioluminescence. The selection of neutrino and muon events requires the implementation of fast and efficient data filtering algorithms for the reduction of accidental background event rates. A possible data filtering scheme for the KM3NeT neutrino telescope is discussed in the paper.

    The ion momentum spectra for nonsequential double ionization of rare gases (He, Ne and Ar) in 23 fs 795 nm laser pulses were measured in the intensity range 0.075-1.25 PW cm{sup -2}. In the studies published, confusing differences in the shape of momentum distributions among different targets are consistently explained within a recollision scenario: excitation during recollision plus subsequent field ionization, not implemented in most theoretical approaches, evidently plays a decisive role for He and Ar nonsequential double ionization whereas it plays only a minor role for Ne.

    Current-bearing wire compensators were successfully used in the 2005-2006 run of the DAΦNE collider to mitigate the detrimental effects of parasitic beam-beam interactions. A marked improvement of the positron beam lifetime was observed in machine operation with the KLOE detector. In view of the possible application of wire beam-beam compensators for the High Luminosity LHC upgrade, we revisit the DAΦNE experiments. We use an improved model of the accelerator with the goal to validate the modern simulation tools and provide valuable input for the LHC upgrade project.

    An interface between an Ar-Ne gas mixture and its own liquid mixture in an equilibrium state has been studied by molecular dynamics simulation with 12-6 Lennard-Jones potential and Lorentz-Berthelot mixing rule. As a result, we accurately evaluate macroscopic variables, and carefully discuss the difference between the stress defined by Bearman and Kirkwood (1958) and that defined by the method of control surface. The result shows that the stress defined by Bearman and Kirkwood is not suitable for describing the detailed structure of vapor-liquid interface of Ar-Ne mixture.

    The charged-current double differential neutrino cross section, measured by the MiniBooNE Collaboration, has been analyzed using a microscopical model that accounts for, among other nuclear effects, long range nuclear (RPA) correlations and multinucleon scattering. We find that MiniBooNE data are fully compatible with the world average of the nucleon axial mass in contrast with several previous analyses which have suggested an anomalously large value. We also discuss the reliability of the algorithm used to estimate the neutrino energy.

Ta kamin, ki so mu raziskovalci namenjali le malo pozornosti, naj bi vseboval prvine »gotike« in »renesanse«, toda te besede leta 1512 niso imele nobenega pomena, preprosto niso obstajale. Edina beseda, ki so jo takrat uporabljali v škofijski palači v Ljubljani, je bila »eleganten«, in to besedo je treba postaviti v nasprotje z drugim izrazom, ki je bil takrat v Evropi zelo v modi, »barbarski«. Med osebnostmi, ki jih je treba umestiti okrog tega dela, sta škof Krištof Ravbar in humanist Avguštin Prygl, opredeliti pa je mogoče tudi širši intelektualni krog z Bernardom Pergerjem, Lorenzom Vallo, Angelom Polizianom in Francescom Colonnom. Če smo pozorni na spise teh avtorjev, še posebej na Colonnove, ni pravega vrednostnega nasprotja med njihovim časom in antiko. Pri njej se navdihujejo, da bi ustvarili govorico – nosilko kulture –, ne da bi zavračali srednjeveško umetnost, pri čemer so spoštovali superiornost krščanstva. Težko je poimenovati bitja, upodobljena na kaminu škofijske palače, in poimenovanje je lahko celo nevarno. Ne smemo prezreti tega semantičnega problema, kajti vsako navajanje imena se sklicuje na določeno kulturno ali jezikovno ozadje, ki nezavedno usmerja naše sklepanje. Prav tako je nemogoče uporabljati besedišče tiste dobe, ker pogosto ne vemo, katere jezike so govorili naročniki in umetniki ter kako so prilagajali ali prevajali določene izraze (to je bil pravi intelektualni problem že okrog leta 1500 – spor o nominalizmu, prve teorije prevajanja, Colonnova semantična oklevanja. Zavedali so se tudi, da ime trdno določi neko poljubno resni

Havana Üniversitesi' ndeki eğitimini takiben, New York Diş Hekimliği Fakültesi' ne kabul edildi. 1888 yılında eğitimini tamamladığında, tekrar Küba' ya döndü. 1889 yılında, Paris ' teki Uluslararası Diş Hekimliği kongresine, Küba ‘ yı temsilen katıldı. Bu toplantı sırasında, Paris 1 te kalması ve mesleğini orada tatbik etmesi yönünde teklif aldı. Bu teklifi kabul ederek, Paris' e yerleşti. Paris Diş Hekimliği Okulu' nda çalışmaya başladı. 1890 yılında klinik öğretici, 1891 yılında yardımcı doçent ve 1895 yılında profesör ün- vanlarını aldı. Söz konusu merkezde, 1905 yılına dek para almadan çalıştı. Paris' teki ilk yıllarında geçimini, latin mahallesindeki küçük bir otelde kiraladığı odayı, diş muayenehanesine dönüştürerek sağladı. Bu yıllarda muayenehanesine pek çok öğrenci gelip gitti. Sonraki yıllarda ise, en büyük destekçisi ve aynı zamanda dostu olan Profesör Poirier ' in de desteği ile, daha iyi bir muhitte muayenehane açma ve çalışma imkanını yakaladı. Dr. Oscar Amoedo, diş hekimliğinin pek çok yönü ile ilgilenmiştir. Yaşamı boyunca 120' den fazla makalesi yayınlanan Amoedo, aynı zamanda şırıngalar, pensler, diş kanalı enstrümanları, artikülatörler de dizayn etmiş ve mevcutlarını da geliştirmiştir. Kokain ve etilen klorid ' in diş hekimliğinde lokal anestezik olarak uygun şekilde kullanılması metodunu Amoedo geliştirmiştir. Maksiller sinüs tümörü tedavisi, diş kökü doldurma teknikleri, diş implantasyonları, dişe direk eklemeler ve eklem problemleri çalıştığı diğer alanlar arasındadır.

    One of the most important reactions which determines the rate of breakout from the hot CNO cycle is the {sup 15}O({alpha},{gamma}){sup 19}Ne. The reaction {sup 18}Ne({alpha},p){sup 21}Na may also provide an alternative breakout route. Experiments are being undertaken at Louvain-La-Neuve using the radioactive {sup 18}Ne beam to study these reactions by measurement of {alpha}({sup 18}Ne,p){sup 21}Na and d({sup 18}Ne,p){sup 19}Ne{sup *} {yields} {sup 15}O + {alpha} (orig.)

    In the last three decades, numerous biopolymeric fractions have been isolated from medicinal plants and used as a source of therapeutic agents. The most promising biopharmacological activities of these biopolymers are their immunomodulatory effects. The biopolymeric fraction RLJ-NE-205 was isolated and purified from the rhizomes of Picrorhiza kurroa. We evaluated the effects of biopolymeric fraction RLJ-NE-205 from P. kurroa on the in vivo immune function of the mouse. Balb/c mice were treated with the biopolymeric fraction RLJ-NE-205 (12.5, 25 and 50 mg/kg body weight) for 14 days with sheep red blood cells (SRBC) as an antigen. Haemagglutination antibody (HA) titre, plaque forming cell (PFC) assay, delayed type hypersensitivity (DTH) reaction, phagocytic index, proliferation of lymphocytes, analysis of cytokines in serum and CD4/CD8 population in spleen (determined by flowcytometry) were studied. At the dose of 50 mg/kg, significant increases in the proliferation of lymphocytes (p<0.001) and cytokine levels (IL-4 and IFN-gamma) in serum (p<0.001) were observed. A dose dependent increase was demonstrated in HA titre (p<0.05), DTH (p<0.01), PFC (p<0.05), phagocytic index (p<0.05) and CD4/CD8 (p<0.01) population. This suggests that the biopolymeric fraction RLJ-NE-205 improves the immune system and might be regarded as a biological response modifier.

    Full Text Available KM3NeT is a future European deep-sea research infrastructure hosting a new generation neutrino detectors that – located at the bottom of the Mediterranean Sea – will open a new window on the universe and answer fundamental questions both in particle physics and astrophysics. International collaborative scientific experiments, like KM3NeT, are generating datasets which are increasing exponentially in both complexity and volume, making their analysis, archival, and sharing one of the grand challenges of the 21st century. These experiments, in their majority, adopt computing models consisting of different Tiers with several computing centres and providing a specific set of services for the different steps of data processing such as detector calibration, simulation and data filtering, reconstruction and analysis. The computing requirements are extremely demanding and, usually, span from serial to multi-parallel or GPU-optimized jobs. The collaborative nature of these experiments demands very frequent WAN data transfers and data sharing among individuals and groups. In order to support the aforementioned demanding computing requirements we enabled Grid Computing resources, operated by EGI, within the KM3NeT computing model. In this study we describe our first advances in this field and the method for the KM3NeT users to utilize the EGI computing resources in a simulation-driven use-case.

    The $^{22}$Ne(p,$\\gamma$)$^{23}$Na reaction is the most uncertain process in the neon-sodium cycle of hydrogen burning. At temperatures relevant for nucleosynthesis in asymptotic giant branch stars and classical novae, its uncertainty is mainly due to a large number of predicted but hitherto unobserved resonances at low energy. Purpose: A new direct study of low energy $^{22}$Ne(p,$\\gamma$)$^{23}$Na resonances has been performed at the Laboratory for Underground Nuclear Astrophysics (LUNA), in the Gran Sasso National Laboratory, Italy. Method: The proton capture on $^{22}$Ne was investigated in direct kinematics, delivering an intense proton beam to a $^{22}$Ne gas target. $\\gamma$ rays were detected with two high-purity germanium detectors enclosed in a copper and lead shielding suppressing environmental radioactivity. Results: Three resonances at 156.2 keV ($\\omega\\gamma$ = (1.48\\,$\\pm$\\,0.10)\\,$\\cdot$\\,10$^{-7}$ eV), 189.5 keV ($\\omega\\gamma$ = (1.87\\,$\\pm$\\,0.06)\\,$\\cdot$\\,10$^{-6}$ eV) and 259.7 keV ($\\o...

    We report here the first observation of electromagnetically induced transparency (EIT) in $^{20}$Ne. The power broadening of the EIT linewidth is measured as a function of neon pressure and RF excitation power. Doppler effects on the EIT broadening are found even at low pressures and low intensities, where the linewidth should be governed only by homogeneous effects.

    2016-05-01

    Recombination of the intrinsic ionic centers Ne{sub 2}{sup +} (self-trapped holes) with the detrapped electrons in solid Ne matrices and relaxation channels have been studied. The experiments were performed employing combination of the cathodoluminescence (CL) with current and optical activation spectroscopy techniques. CL spectra were recorded simultaneously in the VUV and visible range. Yields of spectrally resolved thermally and photon-stimulated luminescence (TSL, PSL) and thermally and photon-stimulated exoelectron emission (TSEE, PSEE) were measured in the time-correlated manner. It was found that the recombination reaction proceeds with irreversible dissociation of the transient Ne{sub 2}{sup ∗∗} centers and the dissociative recombination (DR) products exit the matrix cage. Products of the DR reaction are found to be in 3s and 3p states. The detection of “defect” components in the TSL and PSL points to the defect formation via DR in Ne matrices. The temperature range of the electron traps stability is elucidated. A long-lasting “afteremission” of electrons and afterglow of VUV photons observed on switching off the irradiation suggest the accumulation of the uncompensated negative charge.

    Laser radiation has many applications in biomedical field, such as wound healing, tissue repairing, heating and ablation processes. Intravenous low power laser radiation is used clinically for skin and vascular disorders. Laser radiation improves microcirculation and modulates the rheological properties of blood. FTIR (Fourier Transform Infra Red Spectra) is used to see the structural changes in erythrocyte membrane. In the present work He Ne laser (λ= 632nm, power=2mW) is used to irradiate human Red blood cells. Red blood cells are separated from human whole blood using centrifugation method (time=10 min., temperature=15°C and RPM=3000) and then exposed to HeNe laser radiation. Laser exposure time is varied from 10 min. to 40min for Red blood cells. Absorption spectrum, FTIR and fluorescence spectra of RBC are compared before and after HeNe laser irradiation. The absorption spectrum of RBC after exposure to HeNe laser shows a significant decrease in absorbance. The FTIR spectrum of non irradiated RBC clearly show the peaks due to O-H (free group), C=O (amide I group), N=O (nitro group), C-O (anhydride group) and C-H (aromatic group). Laser radiation changes in transmittance in FTIR spectra related to C=O group and percentage of transmittance increases for O-H, C=C, N=O, C-O and C-H group.

    2015-11-01

    Infrared spectra of Ne-C2D2 are observed in the region of the ν3 fundamental band (asymmetric C-D stretch, ≈2440 cm-1) using a tunable optical parametric oscillator to probe a pulsed supersonic slit jet expansion from a cooled nozzle. Like helium-acetylene, this system lies close to the free rotor limit, making analysis tricky because stronger transitions tend to pile up close to monomer (C2D2) rotation-vibration transitions. Assignments are aided by predicted rotational energies calculated from a published ab initio intermolecular potential energy surface. The analysis extends up to the j = 3←2 band, where j labels C2D2 rotation within the dimer, and is much more complete than the limited infrared assignments previously reported for Ne-C2H2 and Ne-C2HD. Two previous microwave transitions within the j = 1 state of Ne-C2D2 are reassigned. Coriolis model fits to the theoretical levels and to the spectrum are compared. Since the variations observed as a function of C2D2 vibrational excitation are comparable to those noted between theory and experiment, it is evident that more detailed testing of theory will require vibrational averaging over the acetylene intramolecular modes.

  19. Progress On Neutrino-Proton Neutral-Current Scattering In MicroBooNE

    Energy Technology Data Exchange (ETDEWEB)

    2017-01-16

    The MicroBooNE Experiment at the Fermi National Accelerator Laboratory, an 89-ton active mass liquid argon time projection chamber, affords a unique opportunity to observe low-$Q^2$ neutral-current neutrino-proton scattering events. Neutral-current neutrino-proton scattering at $Q^2 < 1$ GeV$^2$ is dominated by the proton's axial form factor, which can be written as a combination of contributions from the up, down, and strange quarks: $G_A(Q^2) = \\frac{1}{2}[-G_A^u(Q^2)+G_A^d(Q^2)+G_A^s(Q^2)]$. The contribution from up and down quarks has been established in past charged-current measurements. The contribution from strange quarks at low $Q^2$ remains unmeasured; this is of great interest since the strange quark contribution to the proton spin can be determined from the low-$Q^2$ behavior: $\\Delta S = G_A^s(Q^2=0)$. MicroBooNE began operating in the Booster Neutrino Beam in October 2015. I will present the status in observing isolated proton tracks in the MicroBooNE detector as a signature for neutral-current neutrino-proton events. The sensitivity of the MicroBooNE experiment for measuring the strange quark contribution to the proton spin will be discussed.

    2011-01-01

    We report the characterization of dark line resonances observed in Cs vapor microcells filled with a unique neon (Ne) buffer gas. The impact on the coherent population trapping (CPT) resonance of some critical external parameters such as laser intensity, cell temperature, and microwave power is studied. We show the suppression of the first-order light shift by proper choice of the microwave power. The temperature dependence of the Cs ground state hyperfine resonance frequency is shown to be canceled in the 77-80 °C range for various Ne buffer gas pressures. The necessity to adjust the Ne buffer gas pressure or the cell dimensions to optimize the CPT signal height at the frequency inversion temperature is pointed out. Based on such Cs-Ne microcells, we preliminary demonstrate a 852 nm vertical cavity surface emitted laser (VCSEL)-modulated based CPT atomic clock exhibiting a short term fractional frequency instability σy(τ)=1.5×10-10τ-1/2 until 30 s. These results, similar to those published in the literature by others groups, prove the potential of our original microcell technology in view of the development of high-performance chip scale atomic clocks.

  3. Evaluating Systematic Dependencies of Type Ia Supernovae: The Influence of Progenitor 22Ne Content on Dynamics

    2009-08-01

    We present a theoretical framework for formal study of systematic effects in supernovae Type Ia (SNe Ia) that utilizes two-dimensional simulations to implement a form of the deflagration-detonation transition (DDT) explosion scenario. The framework is developed from a randomized initial condition that leads to a sample of simulated SNe Ia whose 56Ni masses have a similar average and range to those observed, and have many other modestly realistic features such as the velocity extent of intermediate-mass elements. The intended purpose is to enable statistically well defined studies of both physical and theoretical parameters of the SNe Ia explosion simulation. We present here a thorough description of the outcome of the SNe Ia explosions produced by our current simulations. A first application of this framework is utilized to study the dependence of the SNe Ia on the 22Ne content, which is known to be directly influenced by the progenitor stellar population's metallicity. Our study is very specifically tailored to measure how the 22Ne content influences the competition between the rise of plumes of burned material and the expansion of the star before these plumes reach DDT conditions. This influence arises from the dependence of the energy release, progenitor structure, and laminar flame speed on 22Ne content. For this study, we explore these three effects for a fixed carbon content and DDT density. By setting the density at which nucleosynthesis takes place during the detonation phase of the explosion, the competition between plume rise and stellar expansion controls the amount of material in nuclear statistical equilibrium (NSE) and therefore 56Ni produced. Of particular interest is how this influence of 22Ne content compares to the direct modification of the 56Ni mass via the inherent neutron excess as discussed by Timmes et al. Although the outcome following from any particular ignition condition can change dramatically with 22Ne content, with a sample of 20

Pengujian dilakukan dengan menempatkan minyak nabati diantara polarisator dan analisator. Hasil penelitian pada kedua sumber cahaya menunjukkan pola yang hampir sama. Minyak zaitun dan VCO memiliki perubahan sudut polarisasi alami kecil, sedangkan minyak sawit, kedelai, jelantah, dan curah memiliki perubahan sudut polarisasi alami besar. Besarnya perubahan sudut polarisasi minyak kadaluwarsa lebih besar dibanding minyak baru. Perubahan sudut polarisasi sebanding dengan jumlah radikal bebas (ALB, peroksida dan molekul asimetri (asam lemak jenuh, molekul rantai panjang. Meskipun pola yang dihasilkan oleh kedua sumber cahaya sama, namun lampu IR memberikan nilai perubahan sudut polarisasi yang lebih tinggi dari laser He-Ne. Hal ini dimungkinkan karena daya lampu IR lebih besar dari He-Ne, sehingga energi yang dihasilkan lampu IR lebih tinggi dan perubahan sudut polarisasinya lebih besar. This research based on previous research that using IR lamp (250 watt and He-Ne laser (1 mW on a mixture of palm oil and animal oil.

    Ocean biological, chemical or physical processes occur over widely varying scales in space and time: from micro- to kilometer scales, from less than seconds to centuries. While space systems supply important data and information, insitu data is necessary for comprehensive modeling and forecasting of ocean dynamics. Yet, collection of in-situ observation on these scales is inherently challenging and remains generally difficult and costly in time and resources. This paper address the innovations and significant developments for a new generation of insitu sensors in FP7 European Union project "Next generation, Cost- effective, Compact, Multifunctional Web Enabled Ocean Sensor Systems Empowering Marine, Maritime and Fisheries Management" or "NeXOS" for short. Optical and acoustics sensors are the focus of NeXOS but NeXOS moves beyond just sensors as systems that simultaneously address multiple objectives and applications are becoming increasingly important. Thus NeXOS takes a perspective of both sensors and sensor systems with significant advantages over existing observing capabilities via the implementation of innovations such as multiplatform integration, greater reliability through better antifouling management and greater sensor and data interoperability through use of OGC standards. This presentation will address the sensor system development and field-testing of the new NeXOS sensor systems. This is being done on multiple platforms including profiling floats, gliders, ships, buoys and subsea stations. The implementation of a data system based on SWE and PUCK furthers interoperability across measurements and platforms. This presentation will review the sensor system capabilities, the status of field tests and recommendations for long-term ocean monitoring.

  7. Searches for New Physics at MiniBooNE: Sterile Neutrinos and Mixing Freedom

    The MiniBooNE experiment was designed to perform a search for vμ → ve oscillations in a region of Δm2 and sin2 2θ very different from that allowed by standard, three-neutrino oscillations, as determined by solar and atmospheric neutrino experiments. This search was motivated by the LSND experimental observation of an excess of $\\bar{v}$e events in a $\\bar{v}$μ beam which was found compatible with two-neutrino oscillations at Δm2 ~ 1 eV2 and sin2 2{theta} < 1%. If confirmed, such oscillation signature could be attributed to the existence of a light, mostly-sterile neutrino, containing small admixtures of weak neutrino eigenstates. In addition to a search for vμ → ve oscillations, MiniBooNE has also performed a search for vμ → ve oscillations, which provides a test of the LSND two-neutrino oscillation interpretation that is independent of CP or CPT violation assumptions. This dissertation presents the MiniBooNE vμ → ve and vμ → ve analyses and results, with emphasis on the latter. While the neutrino search excludes the two-neutrino oscillation interpretation of LSND at 98% C.L., the antineutrino search shows an excess of events which is in agreement with the two-neutrino vμ → ve oscillation interpretation of LSND, and excludes the no oscillations hypothesis at 96% C.L. Even though the neutrino and antineutrino oscillation results from MiniBooNE disagree under the single sterile neutrino oscillation hypothesis, a simple extension to the model to include additional sterile neutrino states and the possibility of CP violation allows for differences between neutrino and antineutrino oscillation signatures. In view of that, the viability of oscillation models with one or two sterile neutrinos is investigated in global fits to MiniBooNE and LSND

    The Nuclear Energy Computational Fluid Dynamics Advanced Modeling and Simulation (NE-CAMS) system is being developed at the Idaho National Laboratory (INL) in collaboration with Bettis Laboratory, Sandia National Laboratory (SNL), Argonne National Laboratory (ANL), Utah State University (USU), and other interested parties with the objective of developing and implementing a comprehensive and readily accessible data and information management system for computational fluid dynamics (CFD) verification and validation (V&V) in support of nuclear energy systems design and safety analysis. The two key objectives of the NE-CAMS effort are to identify, collect, assess, store and maintain high resolution and high quality experimental data and related expert knowledge (metadata) for use in CFD V&V assessments specific to the nuclear energy field and to establish a working relationship with the U.S. Nuclear Regulatory Commission (NRC) to develop a CFD V&V database, including benchmark cases, that addresses and supports the associated NRC regulations and policies on the use of CFD analysis. In particular, the NE-CAMS system will support the Department of Energy Office of Nuclear Energy Advanced Modeling and Simulation (NEAMS) Program, which aims to develop and deploy advanced modeling and simulation methods and computational tools for reliable numerical simulation of nuclear reactor systems for design and safety analysis. Primary NE-CAMS Elements There are four primary elements of the NE-CAMS knowledge base designed to support computer modeling and simulation in the nuclear energy arena as listed below. Element 1. The database will contain experimental data that can be used for CFD validation that is relevant to nuclear reactor and plant processes, particularly those important to the nuclear industry and the NRC. Element 2. Qualification standards for data evaluation and classification will be incorporated and applied such that validation data sets will result in well

    Full Text Available A produção de uvas viníferas nas regiões de elevada altitude do estado de Santa Catarina é recente e há poucas informações disponíveis a respeito das características fenológicas e das exigências térmicas para as variedades utilizadas. O objetivo deste trabalho foi caracterizar o comportamento fenológico e determinar as exigências térmicas das variedades Chardonnay, Sauvignon Blanc, Cabernet Sauvignon, Merlot, Pinot Noir, Cabernet Franc e Sangiovese. A área experimental foi instalada na Estação Experimental da EPAGRI, localizada em São Joaquim (28°17'39"S; 49°55'56"W, altitude 1.415m. Os estádios fenológicos avaliados foram início da brotação, floração, mudança de cor das bagas e maturidade nos ciclos produtivos de 2004/05, 2005/06 e 2006/07. A exigência térmica das variedades foi calculada empregando-se o somatório de graus-dia, considerando-se temperatura-base para a videira de 10°C. Na colheita, a maturação tecnológica foi determinada através das análises de sólidos solúveis totais, acidez titulável e pH. O ciclo das variedades viníferas avaliadas na região de São de Joaquim é mais longo do que o observado em outras regiões produtoras do Brasil. A duração térmica é um bom indicador de desenvolvimento das fases do ciclo da videira.

    The portion of Brazilian continental margin located between the Pernambuco Shear Zone (ZCPE) and Touros High, enclosing Natal Platform and Paraiba basin, NE Brazil, presents a thin sedimentary cover represented by Neo- Cretaceous deposits, over an elevated basement. In this zone the narrow platform ends abruptly against the ocean plate, forming a scarped slope. This area corresponds to the Transverse zone of Northeast Brazil (TZN) limited by two extensive transcurrent E-W shear zones that acted as accommodation zones for the strain produced by the advance of the southern and northern rift branches. During the Aptian, the rift suffered a NE deflection and contoured the Borborema Province and the TZN. The resistance of this block to the rift advance generated a prominent and elevated region into the Atlantic gulf which resulted in the absence of rift deposition over the Brazilian margin and its deviation to the African side. The model suggested by this paper denominates this area as the 'exception zone' of the Brazilian margin, which possess a poor petroliferous potential and need to be separated from the sector corresponding to the Pernambuco basin, located to south of ZCPE, representing the last piece of margin before the rift deflection and possessing an important petroliferous potential.

  11. La consommation de propylène en Europe occidentale Propylene Consumption in Western Europe

    2006-11-01

    Full Text Available Les besoins de l'Europe occidentale en propylène utilisé en pétrochimie sont actuellement de 7,4. 10 puissance 6 t/an. Au cours des prochaines années, le taux de progression moyen de la consommation devrait être de l'ordre de 1,8%/an; ainsi en 1995, la pétrochimie européenne utiliserait environ 8,7. 10 puissance 6 t de propylène. L'essentiel de la progression de cette consommation sera dû au fort accroissement de la production de polypropylène et à un degré moindre de l'oxyde de propylène, de l'isopropanol et de l'éthyl-2 hexanol. Par contre les débouchés représentés par l'acrylonitrile et le cumène resteront pratiquement stables. La consommation de propylène dans les productions de butanols devrait diminuer. La part des besoins en propylène satisfaite par les vapocraqueurs européens qui est en 1986 de 82 %, devrait être inférieure à 75 % en 1995. Il sera de plus en plus nécessaire de se tourner vers d'autres sources d'approvisionnement. En 1986 les raffineries européennes ont produit 1,05. 10 puissance 6 t de propylène utilisé en pétrochimie et les importations ont atteint 0,3. 10 puissance 6 t. En 1995 la différence entre la consommation et la production des vapocraqueurs pourrait dépasser 2,0. 10 puissance 6 t. Il semble peu probable que les unités de craquage catalytique puissent combler le déficit sauf si les rendements en propylène augmentent très notablement. On peut s'attendre à la construction de splitters propylène/propane et à une augmentation des importations. D'autre part, en raison de la tension qui risque d'apparaître sur les prix du propylène, l'intérêt de certaines voies de synthèse actuellement considérées comme non rentables pourrait augmenter; ces nouvelles voies sont : - la déshydrogénation du propane déjà considérée dans d'autres régions (Mexique, Indonésie, Malaisie; - la métathèse entre l'éthylène et les butènes-2, pouvant eux-mêmes être produits à partir d'éthylène

    2017-02-02

    The net contribution of the strange quark spins to the proton spin, $\\Delta s$, can be determined from neutral current elastic neutrino-proton interactions at low momentum transfer combined with data from electron-proton scattering. The probability of neutrino-proton interactions depends in part on the axial form factor, which represents the spin structure of the proton and can be separated into its quark flavor contributions. Low momentum transfer neutrino neutral current interactions can be measured in MicroBooNE, a high-resolution liquid argon time projection chamber (LArTPC) in its first year of running in the Booster Neutrino Beamline at Fermilab. The signal for these interactions in MicroBooNE is a single short proton track. We present our work on the automated reconstruction and classification of proton tracks in LArTPCs, an important step in the determination of neutrino- nucleon cross sections and the measurement of $\\Delta s$.

  14. Electron Attenuation Measurement using Cosmic Ray Muons at the MicroBooNE LArTPC

    2017-10-01

    The MicroBooNE experiment at Fermilab uses liquid argon time projection chamber (LArTPC) technology to study neutrino interactions in argon. A fundamental requirement for LArTPCs is to achieve and maintain a low level of electronegative contaminants in the liquid to minimize the capture of drifting ionization electrons. The attenuation time for the drifting electrons should be long compared to the maximum drift time, so that the signals from particle tracks that generate ionization electrons with long drift paths can be detected efficiently. In this talk we present MicroBooNE measurement of electron attenuation using cosmic ray muons. The result yields a minimum electron 1/e lifetime of 18 ms under typical operating conditions, which is long compared to the maximum drift time of 2.3 ms.

    We intend to investigate the charged particle decay modes from the excited states of $^{17}$F populated in the $\\beta^+$- decay of $^{17}$Ne. In particular, we propose to study the proton decay branches to $^{16}$O states which are unstable to $\\alpha$- decay. We plan to use the recently developed ISOLDE Si-ball detector array in order to efficiently detect the charged particles in a wide solid angle. We ask for a total of 12 shifts, including 9 shifts for $^{17}$Ne and 3 shifts for stable beam and calibrations. We request the use of a Mg oxide target coupled to a plasma ion source with cooled transfer line or, if possible, to the new MINIMONOECRIS. We would like to make use of the ISOLDE VME DAQ and CERN data storage system.

    2014-01-01

    Full Text Available Stroke is the first cause of disability. Several robotic devices have been developed for stroke rehabilitation. Robot therapy by NeReBot is demonstrated to be an effective tool for the treatment of poststroke paretic upper limbs, able to improve the activities of daily living of stroke survivors when used both as additional treatment and in partial substitution of conventional rehabilitation therapy in the acute and subacute phases poststroke. This study presents the evaluation of the costs related to delivering such therapy, in comparison with conventional rehabilitation treatment. By comparing several NeReBot treatment protocols, made of different combinations of robotic and nonrobotic exercises, we show that robotic technology can be a valuable and economically sustainable aid in the management of poststroke patient rehabilitation.

    The future KM3NeT neutrino telescope will consist of several thousand digital optical modules (DOMs), each of which will be equipped with 31 3-inch photo-multiplier tubes (PMTs). This design has various advantages over the use of one large PMT per optical module, e.g. concerning effective photocathode area per module, improved background suppression and directional reconstruction. Currently, the KM3NeT collaboration is testing a prototype DOM deployed on the instrumentation line of the ANTARES neutrino telescope. The DOM has been operational since mid-April 2013. First data are presented and compared to simulation results. The results are very encouraging and indicate that muon identification and a coarse direction estimation are possible event with a single DOM.

    The MicroBooNE detector, to be located on axis in the Booster Neutrino Beamline (BNB) at the Fermi National Accelerator Laboratory (Fermilab), consists of two main components: a large liquid argon time projection chamber (LArTPC), and a light collection system. Thirty-two 8-inch diameter Hamamatsu R5912-02mod cryogenic photomultiplier tubes (PMTs) will detect the scintillation light generated in the liquid argon (LAr). This article first describes the MicroBooNE PMT performance test procedures, including how the light collection system functions in the detector, and the design of the PMT base. The design of the cryogenic test stand is then discussed, and finally the results of the cryogenic tests are reported.

    2017-04-01

    In this article, the cluster-cluster interaction between α-clusters in 16O and 20Ne is studied theoretically. Using the generalized Nikiforov-Uvarov (NU) technique, the clusterization energy for these nuclei is calculated. Based on the obtained results, one can find out that the clustering phenomenon does not take place neither at the ground state, nor at the excited states of these nuclei and it is more probable at energies among excited levels. It is shown that the formulation presented for the clustering phenomenon reproduces the results obtained in previous experimental and theoretical attempts. It is worth mentioning that the consistency of the results with the previous experimental and theoretical predictions for clustering phenomenon in 16O and 20Ne indicates the reliability of this formulation for various types of light α-conjugate nuclei, such as 8Be, 12C, 24Mg and so on.

    In this study, we outlined a pragmatic approach for structural studies leading to better understanding of polycarbon structures using 21Ne as a nuclear magnetic resonance (NMR) probe. 21Ne NMR parameters of a single neon atom and its dimer were predicted at the CCSD(T) level in combination with large basis sets. At a lower level of theory, an interaction of neon atom with 1,3-cyclopentadiene ring and with five- and six-membered rings in carbazole was studied using the restricted Hartree-Fock (RHF) and density functional theory (DFT) combined with smaller basis sets. The RHF and DFT modelling of neon interaction with nanosized objects were performed on cyclacenes and selected fullerenes.

    The stereodynamics of the Ne (P2 3 )+Ar Penning and associative ionization reactions have been studied using a crossed molecular beam apparatus. The experiment uses a curved magnetic hexapole to polarize the Ne (P2 3 ) , which is then oriented with a shaped magnetic field in the region where it intersects with a beam of Ar (S 1 ) . The ratios of Penning to associative ionization were recorded over a range of collision energies from 320 to 500 cm-1 and the data were used to obtain Ω state dependent reactivities for the two reaction channels. These reactivities were found to compare favorably to those predicted in the theoretical work of Brumer et al.

    2014-06-14

    Excitation of HeNe by synchrotron light just below the frequency of the 1s → 3p transition of isolated He has been recently shown to be followed by resonant interatomic Coulombic decay (ICD). The vibrationally resolved widths of the ICD states were extracted with high precision from the photoion spectra. In this paper, we report the results of ab initio calculations of these widths. We show that interaction between electronic states at about the equilibrium distance of HeNe makes dark states of He accessible for the photoexcitation and subsequent electronic decay. Moreover, the values of the calculated widths are shown to be strongly sensitive to the presence of the non-adiabatic coupling between the electronic states participating in the decay. Therefore, only by considering the complete manifold of interacting decaying electronic states a good agreement between the measured and computed ICD widths can be achieved.

  12. A combined muon-neutrino and electron-neutrino oscillation search at MiniBooNE

    Energy Technology Data Exchange (ETDEWEB)

    Monroe, Jocelyn Rebecca [Columbia Univ., New York, NY (United States)

    2006-01-01

    MiniBooNE seeks to corroborate or refute the unconfirmed oscillation result from the LSND experiment. If correct, the result implies that a new kind of massive neutrino, with no weak interactions, participates in neutrino oscillations. MiniBooNE searches for vμ → ve oscillations with the Fermi National Accelerator Laboratory 8 GeV beam line, which produces a vμ beam with an average energy of ~ 0.8 GeV and an intrinsic ve content of 0.4%. The neutrino detector is a 6.1 m radius sphere filled with CH2, viewed by 1540 photo-multiplier tubes, and located 541 m downstream from the source. This work focuses on the estimation of systematic errors associated with the neutrino flux and neutrino interaction cross section predictions, and in particular, on constraining these uncertainties using in-situ MiniBooNE vμ charged current quasielastic (CCQE) scattering data. A data set with ~ 100,000 events is identified, with 91% CCQE purity. This data set is used to measure several parameters of the CCQE cross section: the axial mass, the Fermi momentum, the binding energy, and the functional dependence of the axial form factor on four-momentum transfer squared. Constraints on the vμ and ve fluxes are derived using the vμ CCQE data set. A Monte Carlo study of a combined vμ disappearance and ve appearance oscillation fit is presented, which improves the vμ → ve oscillation sensitivity of MiniBooNE with respect to a ve appearance-only fit by 1.2-1.5σ, depending on the value of Δm2.

    The Distilbène® story is a dramatic episode which belongs to the history of medicine. It provided several useful lessons such as the importance of evidence-based medicine and the hazard to develop treatments during pregnancy without careful animal verifications. However, this experience has also provided unexpected progress by suggesting new pathophysiological concepts: fetal programming of adult diseases and/or transgenerational transmission of environmental effects through epigenetic modifications.

    The low-noise operation of readout electronics in a liquid argon time projection chamber (LArTPC) is critical to properly extract the distribution of ionization charge deposited on the wire planes of the TPC, especially for the induction planes. This paper describes the characteristics and mitigation of the observed noise in the MicroBooNE detector. The MicroBooNE's single-phase LArTPC comprises two induction planes and one collection sense wire plane with a total of 8256 wires. Current induced on each TPC wire is amplified and shaped by custom low-power, low-noise ASICs immersed in the liquid argon. The digitization of the signal waveform occurs outside the cryostat. Using data from the first year of MicroBooNE operations, several excess noise sources in the TPC were identified and mitigated. The residual equivalent noise charge (ENC) after noise filtering varies with wire length and is found to be below 400 electrons for the longest wires (4.7 m). The response is consistent with the cold electronics design expectations and is found to be stable with time and uniform over the functioning channels. This noise level is significantly lower than previous experiments utilizing warm front-end electronics.

    L'ajout de certains oxydes dans un verre initialement homogène peut entraîner des cristallisations plus ou moins importantes du mélange lors de son refroidissement. Parmi les oxydes connus pour induire de tels phénomènes dans des verres de silicates, se trouvent l'oxyde de molybdène MoO{3} et l'oxyde de phosphore P{2}O{5}. Les matériaux étudiés ici sont des verres silico-sodo-calciques auxquels ont été ajoutés MoO{3} et P{2}O{5} en quantité variable, ce qui provoque des cristallisations importantes. L'identification et la quantification des phases cristallines en présence par MEB et méthode Rietveld à partir des diffractogrammes permettent de comprendre les rôles respectifs du molybdène et du phosphore dans les phénomènes de cristallisation intervenant dans ces verres.

    Two-proton decay of the unbound $ T_{z} =-2$ nucleus$^{16}$Ne , produced in one-neutron knockout from a 500 MeV/u$^{17}$Ne beam, has been studied at GSI. The ground state, at a resonance energy 1.388(15) MeV, ( $ \\Gamma =0.082(15)$ MeV) above the$^{14}$O +p+p threshold, and two narrow resonances at $ E_{r} =3.220(46)$ MeV and 7.57(6) MeV have been investigated. A comparison of the energy difference between the first excited 2$^{+}$ state and the 0$^{+}$ ground state in$^{16}$Ne with its mirror nucleus$^{16}$C reveals a small Thomas-Ehrman shift (TES) of $ +70(46)$ keV. A trend of the TES for the T = 2 quintet is obtained by completing the known data with a prediction for$^{16}$F obtained from an IMME analysis. The decay mechanisms of the observed three resonances were revealed from an analysis of the energy and angular correlations of the$^{14}$O +p+p decay products. The ground state decay can be considered as a genuine three-body (democratic) mode and the excited states decay sequentially via states in the i...

    The MiniBooNE-DM Collaboration searched for vector-boson mediated production of dark matter using the Fermilab 8-GeV Booster proton beam in a dedicated run with 1.86 ×1 020 protons delivered to a steel beam dump. The MiniBooNE detector, 490 m downstream, is sensitive to dark matter via elastic scattering with nucleons in the detector mineral oil. Analysis methods developed for previous MiniBooNE scattering results were employed, and several constraining data sets were simultaneously analyzed to minimize systematic errors from neutrino flux and interaction rates. No excess of events over background was observed, leading to a 90% confidence limit on the dark matter cross section parameter, Y =ɛ2αD(mχ/mV)4≲10-8 , for αD=0.5 and for dark matter masses of 0.01

    The network analysis tools (NeAT) (http://rsat.ulb.ac.be/neat/) provide a user-friendly web access to a collection of modular tools for the analysis of networks (graphs) and clusters (e.g. microarray clusters, functional classes, etc.). A first set of tools supports basic operations on graphs (comparison between two graphs, neighborhood of a set of input nodes, path finding and graph randomization). Another set of programs makes the connection between networks and clusters (graph-based clustering, cliques discovery and mapping of clusters onto a network). The toolbox also includes programs for detecting significant intersections between clusters/classes (e.g. clusters of co-expression versus functional classes of genes). NeAT are designed to cope with large datasets and provide a flexible toolbox for analyzing biological networks stored in various databases (protein interactions, regulation and metabolism) or obtained from high-throughput experiments (two-hybrid, mass-spectrometry and microarrays). The web interface interconnects the programs in predefined analysis flows, enabling to address a series of questions about networks of interest. Each tool can also be used separately by entering custom data for a specific analysis. NeAT can also be used as web services (SOAP/WSDL interface), in order to design programmatic workflows and integrate them with other available resources. PMID:18524799

    Several studies showed the effect of osteopathic manipulative treatment on neonatal care in reducing length of stay in hospital, gastrointestinal problems, clubfoot complications and improving cranial asymmetry of infants affected by plagiocephaly. Despite several results obtained, there is still a lack of standardized osteopathic evaluation and treatment procedures for newborns recovered in neonatal intensive care unit (NICU). The aim of this paper is to suggest a protocol on osteopathic approach (NE-O model) in treating hospitalized newborns. The NE-O model is composed by specific evaluation tests and treatments to tailor osteopathic method according to preterm and term infants' needs, NICU environment, medical and paramedical assistance. This model was developed to maximize the effectiveness and the clinical use of osteopathy into NICU. The NE-O model was adopted in 2006 to evaluate the efficacy of OMT in neonatology. Results from research showed the effectiveness of this osteopathic model in reducing preterms' length of stay and hospital costs. Additionally the present model was demonstrated to be safe. The present paper defines the key steps for a rigorous and effective osteopathic approach into NICU setting, providing a scientific and methodological example of integrated medicine and complex intervention.

    To overcome the limitations of conventional jet nebulizers, vibrating mesh technology has been commercialized. The present article is designed to address clinically relevant issues for routine aerosol therapy for a vibrating mesh nebulizer, the Omron NE U22, compared to traditional jet nebulizers. Inhaled mass (IM), residual activity, particle distribution, including mass median aerodynamic diameter (MMAD) and run time, were determined for radiolabeled albuterol (2.5 mg/3 mL). Omron NE U22, Pari LC Plus, and Sidestream nebulizers were tested. The Omron was tested in two positions, tilted and horizontal. Finally robustness of the Omron NE U22 was determined by repeating treatment 60 times. All Omron experiments were performed using continuous operation. IM for Omron and Pari were similar (20% of nebulizer charge) and greater than the Sidestream (10%). MMADs were similar for all devices but variability was much greater for Omron in the horizontal position. Run time in the tilted position was three times longer when compared to the horizontal (p = 0.02). IM and MMAD were unchanged after Omron robustness testing. Position was an important factor for the mesh device affecting run time and variability in particle distribution. Using a common commercial formulation and continuous operation, drug delivery was similar to an efficient jet nebulizer. The Omron mesh tolerated repeated use with the albuterol formulation.

    The Neuropsychological Screening Battery for Hispanics (NeSBHIS; Pontón et al., 1996) was developed to provide clinicians and researchers with appropriate tests and norms to assess the Latino population. However, the construct validity of the NeSBHIS is unclear, and its clinical utility is untested. This study provides data on the construct validity of this battery via factor analytic methodology. Five factors were identified: (a) a language factor, which included the Controlled Oral Word Association Test, the Pontón-Satz Boston Naming Test, and the Escala de Inteligencia Wechsler para Adultos (EIWA; Wechsler, Green, & Martinez, 1968) Digit Span; (b) a verbal learning factor, which included all the World Health Organization--University of California, Los Angeles Auditory Verbal Learning Test scores (Trials V, VII, and VIII); (c) an attentional-mental control factor, which included the EIWA Digit Symbol, Color Trails 1 and 2, and the EIWA Block Design; (d) a visuospatial factor, made up of the Rey-Osterrieth Complex Figure Test Copy and Memory and the Raven's Standard Progressive Matrices total score; and (e) a psychomotor factor, the Pin Test. This was a stable factor structure, suggesting that the NeSBHIS has a robust construct validity.

This model was developed to maximize the effectiveness and the clinical use of osteopathy into NICU. Results The NE-O model was adopted in 2006 to evaluate the efficacy of OMT in neonatology. Results from research showed the effectiveness of this osteopathic model in reducing preterms’ length of stay and hospital costs. Additionally the present model was demonstrated to be safe. Conclusion The present paper defines the key steps for a rigorous and effective osteopathic approach into NICU setting, providing a scientific and methodological example of integrated medicine and complex intervention.

    Relatively little is known about the dynamics of electron transfer reactions at low collision energy. We present a study of Penning ionization of ground state methyl fluoride molecules by electronically excited neon atoms in the 13 $\\mu$eV--4.8 meV (150 mK--56 K) collision energy range, using a neutral-neutral merged beam setup. Relative cross sections have been measured for three Ne($^3P_2$)+ CH$_3$F reaction channels by counting the number of CH$_3$F$^+$, CH$_2$F$^+$, and CH$_3^+$ product ions, as a function of relative velocity between the neon and methyl fluoride molecular beams. Experimental cross sections markedly deviate from the Langevin capture model at collision energies above 20 K. The branching ratios are constant. In other words, the chemical shape of the CH$_3$F molecule, as seen by Ne($^3P_2$) atom, appears not to change as the collision energy is varied, in contrast to related Ne($^3P_J$) + CH$_3$X (X=Cl and Br) reactions at higher collision energies.

    The MiniBooNE-DM Collaboration searched for vector-boson mediated production of dark matter using the Fermilab 8-GeV Booster proton beam in a dedicated run with 1.86×10^{20} protons delivered to a steel beam dump. The MiniBooNE detector, 490 m downstream, is sensitive to dark matter via elastic scattering with nucleons in the detector mineral oil. Analysis methods developed for previous MiniBooNE scattering results were employed, and several constraining data sets were simultaneously analyzed to minimize systematic errors from neutrino flux and interaction rates. No excess of events over background was observed, leading to a 90% confidence limit on the dark matter cross section parameter, Y=ε^{2}α_{D}(m_{χ}/m_{V})^{4}≲10^{-8}, for α_{D}=0.5 and for dark matter masses of 0.01dark matter. This is the best limit from a dedicated proton beam dump search in this mass and coupling range and extends below the mass range of direct dark matter searches. These results demonstrate a novel and powerful approach to dark matter searches with beam dump experiments.

    We measured the transmission of 3 keV Ne sup 7 sup + ions through capillaries of 100 nm diameter and 10 mu m length produced by etching ion tracks in a polyethylene terephthalate polymer foil. The foils were tilted up to +-25 deg. for which the incident ions are forced to interact with the capillary surface. The majority of Ne sup 7 sup + ions were found to survive the transmission in their initial charge state. For tilted foils the angular distributions of the transmitted particles indicate propagation of the Ne sup 7 sup + ions parallel to the capillary axis. This capillary guiding of the Ne sup 7 sup + ion provides evidence that part of the ions deposit charges within the capillaries in a self-organizing process so that a considerable fraction of the ions is transmitted through the capillaries. A non-linear model is introduced to describe the essential features of the capillary guiding.

    The SW Barents Sea margin developed from a megashear zone which linked the Norwegian-Greenland Sea and the Artic Eurasia Basin during the initial Eocene opening. Within the dextral megashear system, a series of deep and narrow basins formed in the SW Barents Sea. These basins formed in response to multiple rift events and rapid differential subsidence. The distribution of salt structures both in the SW Barents Sea and on the conjugate NE Greenland margin reflects the Late Paleozoic basin configuration. Late Middle Jurassic to Early Cretaceous rifting affected all deep basins in the SW Barents Sea (e.g., Bjørnøya, Tromsø, Harstad and Sørvestsnaget basins) as on the mid-Norwegian margin and the conjugate NE Greenland margin. Following rifting, a wide region subsided and was covered by thick Cretaceous strata. Late Cretaceous-Paleocene rifting between Norway and Greenland was taken up within the megashear zone and pull-apart basins formed in the SW Barents Sea and in the Wandel Sea Basin in NE Greenland. Contraction/inversion formed structural highs separating distinct Late Cretaceous depocenters that continued to subside rapidly. The rifting culminated in crustal breakup and accretion of oceanic crust near the Paleocene-Eocene transition. NE Atlantic breakup was accompanied by large-scale igneous activity, which also affected parts of the SW Barents Sea margin. The sheared Senja FZ margin is segmented, each segment having different structural styles reflecting a complex interplay between the geometry of the sheared margin segments and the opening direction. A continental sliver was also cut off the SW Barents Sea margin, now forming the Greenland Ridge which is a protrusion of the NE Greenland margin. The continent-ocean transition is confined within a narrow zone, bounded by a characteristic marginal high along the Senja Fracture Zone. During Eocene, the Harstad and southern Sørvestsnaget basins developed as narrow, elongated, en echelon basins landward of the

    NE-KAMS knowledge base will assist computational analysts, physics model developers, experimentalists, nuclear reactor designers, and federal regulators by: (1) Establishing accepted standards, requirements and best practices for V&V and UQ of computational models and simulations, (2) Establishing accepted standards and procedures for qualifying and classifying experimental and numerical benchmark data, (3) Providing readily accessible databases for nuclear energy related experimental and numerical benchmark data that can be used in V&V assessments and computational methods development, (4) Providing a searchable knowledge base of information, documents and data on V&V and UQ, and (5) Providing web-enabled applications, tools and utilities for V&V and UQ activities, data assessment and processing, and information and data searches. From its inception, NE-KAMS will directly support nuclear energy research, development and demonstration programs within the U.S. Department of Energy (DOE), including the Consortium for Advanced Simulation of Light Water Reactors (CASL), the Nuclear Energy Advanced Modeling and Simulation (NEAMS), the Light Water Reactor Sustainability (LWRS), the Small Modular Reactors (SMR), and the Next Generation Nuclear Power Plant (NGNP) programs. These programs all involve computational modeling and simulation (M&S) of nuclear reactor systems, components and processes, and it is envisioned that NE-KAMS will help to coordinate and facilitate collaboration and sharing of resources and expertise for V&V and UQ across these programs. In addition, from the outset, NE-KAMS will support the use of computational M&S in the nuclear industry by developing guidelines and recommended practices aimed at quantifying the uncertainty and assessing the applicability of existing analysis models and methods. The NE-KAMS effort will initially focus on supporting the use of computational fluid dynamics (CFD) and thermal hydraulics (T/H) analysis for M&S of nuclear

    The level of ultraviolet-B (UV-B) radiation on the Earth’s surface has increased due to depletion of the ozone layer. Here, we explored the effects of continuous wave He-Ne laser irradiation (632 nm, 5 mW mm-2, 2 min d-1) on the physiological indexes of wheat seedlings exposed to enhanced UV-B radiation (10 KJ m-2 d-1) at the early growth stages. Wheat seedlings were irradiated with enhanced UV-B, He-Ne laser treatment or a combination of the two. Enhanced UV-B radiation had deleterious effects on wheat photosynthesis parameters including photosystem II (chlorophyll content, Hill reaction, chlorophyll fluorescence parameters, electron transport rate (ETR), and yield), the thylakoid (optical absorption ability, cyclic photophosphorylation, Mg2+-ATPase, and Ca2+-ATPase) and some enzymes in the dark reaction (phosphoenolpyruvate carboxylase (PEPC), carbonic anhydrase (CA), malic dehydrogenase (MDH), and chlorophyllase). These parameters were improved in UV-B-exposed wheat treated with He-Ne laser irradiation; the parameters were near control levels and the enzyme activities increased, suggesting that He-Ne laser treatment partially alleviates the injury caused by enhanced UV-B irradiation. Furthermore, the use of He-Ne laser alone had a favourable effect on seedling photosynthesis compared with the control. Therefore, He-Ne laser irradiation can enhance the adaptation capacity of crops.

    We have studied, via laser absorption spectroscopy, the velocity distribution of (7)Li atoms released from a solid neon matrix at cryogenic temperatures. The Li atoms are implanted into the Ne matrix by laser ablation of a solid Li precursor. A heat pulse is then applied to the sapphire substrate sublimating the matrix together with the isolated atoms at around 12 K. We find interesting differences in the velocity distribution of the released Li atoms from the model developed for our previous experiment with Cr [R. Lambo, C. C. Rodegheri, D. M. Silveira, and C. L. Cesar, Phys. Rev. A 76, 061401(R) (2007)]. This may be due to the sublimation regime, which is at much lower flux for the Li experiment than for the Cr experiment, as well as to the different collisional cross sections between those species to the Ne gas. We find a drift velocity compatible with Li being thermally sublimated at 11-13 K, while the velocity dispersion around this drift velocity is low, around 5-7 K. With a slow sublimation of the matrix we can determine the penetration depth of the laser ablated Li atoms into the Ne matrix, an important information that is not usually available in most matrix isolation spectroscopy setups. The present results with Li, together with the previous results with Cr suggest this to be a general technique for obtaining cryogenic atoms, for spectroscopic studies, as well as for trap loading. The release of the isolated atoms is also a useful tool to study and confirm details of the matrix isolated atoms which are masked or poorly understood in the solid. © 2011 American Institute of Physics

    Understanding the electron confinement of local helicity injection (LHI) is critical in order to evaluate its scalability as a startup technique to MA-class devices. Electron confinement in the Pegasus Toroidal Experiment is investigated using multi-point Thomson scattering (TS). The Pegasus TS system utilizes a set of high-throughput transmission gratings and intensified CCDs to measure Te and ne profiles. Previous TS measurements indicated peaked Te profiles 120 eV in outboard injector discharges characterized by strong inductive drive and low LHI drive. Injectors designed to have dominant non-inductive drive have recently been installed in the divertor region of Pegasus to understand the relationship between effective drive voltage, Veff, and plasma performance. At low Veff and reduced plasma current, Ip 60 kA, TS measurements reveal a flat Te profile 50 eV, with a peaked ne profile 1 ×1019 m-3, resulting in a slightly peaked pe profile. As current drive is increased, the Te profiles become hollow with a core Te 50 eV and an edge Te 120 -150 eV. These hollow profiles appear after the start of the Ip flattop and are sustained until the discharge terminates. The ne profiles drop in magnitude to < 1 ×1019 m-3 but remain somewhat peaked. Initial results suggest a weak scaling between input power and core Te. Additional studies are planned to identify the mechanisms behind the anomalous profile features.

  17. Effect of Aseismic Ridge Subduction on Volcanism in the NE Lesser Antilles Arc

    The interaction of aseismic ridges or buoyant crust in subduction zones can affect the volcanism occurring on the overriding plate. Here we describe the affect of the subduction of an aseismic ridge on volcanism in the NE Lesser Antilles. The Lesser Antilles island arc is a result of westward subduction of the North American plate beneath the Caribbean plate and stretches 800 km from Saba in the north to Grenada in the south. From Guadeloupe northwards, the arc bifurcates into an eastern, inactive arc (known as the Limestone Caribees) and a western, active arc (Volcanic Caribees). It has been suggested that this bifurcation is the result of the subduction of buoyant crust in the form of at least two aseismic ridges, in the North American plate. In 2012, IODP Expedition 340 recovered 130 m of core from site U1396, located 55 km SW of Montserrat, Lesser Antilles. The core contains a detailed record of volcanism, in the form of more than 180 tephra layers, that stretches back nearly 4.5 Ma. This is the longest and most complete record of volcanism for the NE Lesser Antilles and provides insight into the evolution and development of the island arc in this region. A variety of techniques are being applied to the tephra layers from U1396 to determine their age, chemistry, components and origin. Here we present preliminary results from paeleomagnetic age determinations for each tephra layer to show how the subduction of aseismic ridges on the North American plate has affected the rate of volcanism and development of the island arc in the NE Lesser Antilles over the last 4.5 Ma.

    Hydro-Period Influence on Kettle Hole Biogeochemistry in NE Germany Kettle holes are glacially created ponds (Kettle holes are only seasonally connected to streams or groundwater and therefore they undergo pronounced short-term changes in the hydro-periods, i.e. water level fluctuations that include complete desiccation and rewetting. Little is known about kettle hole biogeochemistry in NE Germany, especially with regards to the hydro-period. We hypothesized that a connection exists between kettle hole hydro-period and sediment biogeochemistry. We surveyed kettle hole water in NE Germany over several years to capture the seasonal isotopic composition (δD, δ18O). Within a subset of the surveyed kettle holes we measured the δ13C and δ15N composition of sediments at two different depths from one season. Our objective was to link the abiotic influences demarked by the evaporative isotopic signal from kettle hole water, to biotic processes, such as microbial turnover and contributions of vegetation, imprinted in the δ13C and δ15N signals in sediment organic matter. Based on the upper sediment isotopic signal, we were able to classify two categories: permanently and temporarily filled kettle holes. Other kettle holes, for example those found in forests, were not as easily classified. Within the deeper sediment layers we found a distinct curve linear response between δ15N and C/N ratios, where temporarily filled kettle holes were consistently enriched, indicating a higher level of microbial transformation. We evaluated our evaporation estimates against the sediment-based classification to test evaporation as a major mechanism behind kettle hole biogeochemistry. While the temporarily filled kettle holes are the most biogeochemically dynamic, due in large part to their hydro-period, the mechanisms underlying the hydro-period and the concurrent effects on biogeochemical cycles are diverse.

  19. Effect of Land Use Legacy on Forest Carbon Dynamics in the NE U.S.

    Forest stand age is a prime determinant of the strength of the carbon sink, as younger, growing forests tend to be stronger sinks than more mature forests. The substantial carbon sink in the NE U.S. is due to forests regrowing from previous disturbance. The particular type of disturbance, whether agricultural abandonment, timber harvest, or fire, can have an impact on the Net Ecosystem Productivity (NEP) observed today, especially for more recently disturbed forests. Nutrient levels, particularly nitrogen, are the most important factor determining the rate of regrowth following disturbance. Agriculture results in depletion of nutrients from the soil, so often results in slower regrowth than timber harvest, for example. If fire is also used during harvesting, nutrient depletion may be even more severe. This study will use the 1 km USDA forest stand age data for the NE U.S. for a series of model sensitivity experiments with the TEM-Hydro model. Three simulations will apply a single disturbance to result in the correct stand age, with agricultural abandonment, timber harvest, and fire applied at the year of disturbance, respectively. A 1/8o run will explore how aggregated stand age affects NEP relative to higher resolution stand age. Preliminary results for a single grid in PA show timber harvest has faster regrowth than regrowth from agricultural abandonment, though fertilization quickens regrowth rates. The effect of crops on NEP is a larger sink than timber harvest in the 5 years following disturbance, but a smaller sink in the decades following, with equivalent NEP values after about 50 years. A simple stand age mixture experiment shows that heterogeneous stand age matters most in the first 20 years following disturbance. These methods will be applied to realistic stand ages for the entire NE U.S. to determine the importance of disturbance type on forest regrowth.

    A prototype detection unit of the KM3NeT deep-sea neutrino telescope has been installed at 3500m depth 80 km offshore the Italian coast. KM3NeT in its final configuration will contain several hundreds of detection units. Each detection unit is a mechanical structure anchored to the sea floor, held vertical by a submerged buoy and supporting optical modules for the detection of Cherenkov light emitted by charged secondary particles emerging from neutrino interactions. This prototype string implements three optical modules with 31 photomultiplier tubes each. These optical modules were developed by the KM3NeT Collaboration to enhance the detection capability of neutrino interactions. The prototype detection unit was operated since its deployment in May 2014 until its decommissioning in July 2015. Reconstruction of the particle trajectories from the data requires a nanosecond accuracy in the time calibration. A procedure for relative time calibration of the photomultiplier tubes contained in each optical module is described. This procedure is based on the measured coincidences produced in the sea by the {sup 40}K background light and can easily be expanded to a detector with several thousands of optical modules. The time offsets between the different optical modules are obtained using LED nanobeacons mounted inside them. A set of data corresponding to 600 h of livetime was analysed. The results show good agreement with Monte Carlo simulations of the expected optical background and the signal from atmospheric muons. An almost background-free sample of muons was selected by filtering the time correlated signals on all the three optical modules. The zenith angle of the selected muons was reconstructed with a precision of about 3 {sup circle}. (orig.)

    Interatomic Coulombic Decay (ICD) is a relaxation phenomenon, which takes place in weakly bound atomic and molecular systems, typically within a few to hundreds of femtoseconds depending on the system and the particular decay mechanism. The creation of ICD-active states requires the production of highly excited systems, usually populated by innershell ionization or excitation. To this end, XUV and X-ray radiation from synchrotrons was conventionally applied for the majority of experiments due to the desired state-selective ionization of certain sub-shells. The advent of Free-Electron Lasers (FELs) has enabled an entirely new class of experiments, which finally allow to trace ICD directly in the time domain due to the femtosecond pulse duration. Within this paper, the first time-resolved ICD measurement using an XUV-pump–XUV-probe scheme will be discussed in detail. The experiment was performed on neon dimers and ICD was triggered by removing a 2s electron from one of the neon atoms using a 58 eV pulse from the FEL in Hamburg (FLASH). The onset of ICD was probed with a delayed copy of the trigger pulse that further ionized one of the two Ne{sup +} ions emerging after ICD. Thus, the delay-dependent yield of coincident Ne{sup +} + Ne{sup 2+} ion pairs contains the lifetime of the 2s-innershell vacancy decaying via ICD. The result of 150 fs ± 50 fs is in good agreement with theory but only for those calculations that explicitly take nuclear motion into account.

    Full Text Available Terpolímeros de poli(álcool vinílico foram sintetizados por meio de reação de esterificação do PVA parcialmente hidrolisado com cloretos de ácidos graxos de comprimento de cadeia diferentes. O objetivo da síntese foi obter polímeros à base de PVA com pequenas variações no balanço hidrófilo/lipófilo e nas propriedades interfaciais de suas soluções. A modificação foi acompanhada por ressonância magnética nuclear de hidrogênio e as propriedades foram avaliadas pela variação na solubilidade e na tensão superficial. Foram obtidos polímeros modificados com baixos teores de grupamento hidrófobo. Testes de tensão superficial, realizados com os produtos solúveis em água, não mostraram variação dessa propriedade. A solubilidade dos produtos diminuiu sensivelmente mesmo para pequenas incorporações de grupamento hidrófobo. Foi observado que, para uma mesma massa, segmentos hidrófobos menores, distribuídos ao longo da cadeia, promovem maior modificação na solubilidade.Poly(vinyl alcohol terpolymers have been obtained by reaction of partially hydrolized poly(vinyl alcohol with different acid chlorides. The objective is the preparation of polymers with slight differences in their hydrophilic/lipophilic balance and in the interfacial activities of their solutions. The chemical modifications were characterized by means of ¹H NMR and the polymer properties were evaluated in terms of changes in solubility and surface tension. By chemical modification, polymers with low percentage of hydrophobic group were obtained. The water-soluble polymers obtained did not have the surface tension of their solutions altered. The solubility of the modified polymers decreased markedly, even with low contents of hydrophobic groups.

    Full Text Available Hidroxissais lamelares de zinco foram intercalados com corantes aniônicos azo, obtendo-se pigmentos de coloração laranja. Os materiais foram caracterizados por difração de raios X (XRD, espectroscopia vibracional na região do infravermelho com transformada de Fourier (FTIR, análise térmica (TGA/DTA/DSC e espectroscopia fotoeletrônica de raios X (XPS. Após caracterização, os pigmentos lamelares foram dispersos em uma matriz de poli(álcool vinílico - PVA, em concentrações variáveis, em relação à massa de PVA. Filmes homogêneos, transparentes e coloridos foram obtidos pelo método de "casting" úmido e mantidos em dessecador em umidade controlada de 65 % por uma semana e avaliados quanto às suas propriedades mecânicas. Devido às diferentes polaridades dos ânions intercalados, diferentes comportamentos foram observados para os pigmentos quando utilizados como cargas em PVA. Esse trabalho abre uma frente de pesquisas na utilização de hidroxissais lamelares intercalados com corantes aniônicos, como cargas alternativas em materiais compósitos poliméricos.Layered zinc hydroxide salts were intercalated with anionic azo dyes, obtaining orange pigments. The materials were characterized by X-ray diffraction (XRD, Fourier Transform Infrared spectroscopy (FTIR, thermal analysis (TGA/DTA/DSC and X-ray photoelectron spectroscopy (XPS. After characterization, the layered pigments were dispersed into a matrix of poly(vinyl alcohol - PVA, in variable concentrations, in relation to the PVA mass. Homogeneous, transparent and colorful films were obtained by wet casting method and kept in a desiccator at 65% of humidity for one week and evaluated in relation to their mechanical properties. Owing to the different intercalated anions polarities, different behaviors were observed for both pigments when used as fillers in PVA. This work opens a research front in the utilization of layered hydroxide salt intercalated with anionic dyes, as

    The dependence of the avalanche charge gain in Thick Gas Electron Multipliers (THGEM) on the purity of Ne, Ar and Xe filling gases was investigated. The gain, measured with alpha-particles in standard conditions (atmospheric pressure, room temperature), was found to considerably drop in gases purified by non-evaporable getters. On the other hand, small N2 admixtures to noble gases resulted in high reachable gains. The results are of general relevance in the operation of gas-avalanche detectors in noble gases, particularly that of two-phase cryogenic detectors for rare events.

    The interatomic V(r) found by potential-model calculations is compared to an ab initio calculation of the intermolecular potential for NeH+ due to Peyerimhoff (1965). The reason for a rather significant difference in the two results is discussed, and a new method due to Remler (1971) involving Regge poles is applied. The method can be used to calculate the differential cross section, where the starting point for such calculations is based on intuition in light of the classical deflection function.

    The heavy-ion induced excitation of the quadrupole resonance in /sup 58/Ni has been studied with /sup 20/Ne beams of 14.5 and 19.6 MeV/N incident energy. The broad resonance structure is clearly observed; the strength exhausts 44% and 60% of the energy weighted sum rule (EWSR) at the two incident energies, respectively. The background is partly explained by a three-body reaction mechanism, which is based on the one-nucleon pick-up reaction into unbound states followed by one- nucleon emission. The remaining part is interpreted as inelastic excitation of other multipoles. (11 refs).

    Single electron capture in collisions of 9 keV/q Ne7+-ions with He has been studied using cold-target recoil-ion momentum spectroscopy (COLTRIMS). With an improved apparatus a longitudinal momentum resolution of 0.07 a.u. has been achieved. This momentum component corresponds to the binding energy of the active electron in the final state. For the first time state-resolved differential cross sections have been determined with respect to the main quantum number, subshell level and spin state of the captured electron.

    Double ionization of Ne by 25 fs, 1.0 PW cm{sup -2} laser pulses has been explored in a kinematically complete experiment using a 'reaction microscope'. Electrons are found to be emitted into a narrow cone along the laser polarization ({epsilon}), much more confined than for single ionization, with a broad maximum in their energy distribution along {epsilon}. Correlated momentum spectra show both electrons being ejected into the same hemisphere, in sharp contrast to predictions based on field-free (e, 2e) recollision dynamics, but in overall agreement with recent semiclassical calculations for He.

    KM3NeT is a future multi-cubic-kilometer neutrino telescope in the Mediterranean Sea. As a first step towards project implementation, a preproduction model of the telescope detection unit will be produced and deployed in the sea in March 2013. The detection unit is a flexible, vertical structure of a few 100 m length holding digital optical modules (DOMs). A facet-like DOM encapsulates 31 photomultiplier tubes of 80 mm diameter inside of 17-inch pressure resistant glass sphere. One of such DOMs will be produced at Erlangen Centre for Astroparticle Physics. This contribution describes design, functionality and assembly of the DOM.

  13. The Passive Personality Principle and the General Principle of Ne Bis In Idem

    2013-09-01

    Full Text Available This paper demonstrates the interest which a victim of a transnational crime may have in moving proceedings across the border. It also considers the means with which this can be done. By virtue of the passive personality principle, a Swiss victim can move proceedings back to Switzerland for a civil claim which would not otherwise have a forum in Switzerland. Further, it is suggested that there is a conflict between the passive personality principle and the prohibition of double jeopardy. This paper argues for a restrictive interpretation of the passive personality principle  and a broadening of the principle of ne bis in idem.

    Full Text Available In underwater neutrino telescopes, the search of point-like sources through the Cherenkov detection technique requires a precise knowledge of the positions of thousands of optical sensors, spread in a volume of a few cubic kilometres. In KM3NeT the optical sensors are hosted in 700 m high semi-rigid structures, called detection units, which move under the effects of underwater currents. These movements are continuously monitored through an underwater positioning system based on acoustic emitters and receivers. In this work, the tests performed on the key elements of the positioning system are presented.

    2015-06-01

    Full Text Available In Dio ne scampi dagli Orsenigo Vittorio Imbriani grapples with the form of the novel. In a dialectical fashion, explicit quotations (frequently from French sources clarify his position towards generic paradigms. This article attempts to group these quotations on the basis of their literary genres in order to stress the complexities of an inclusive and versatile text. The intertextual network, ranging from feuilleton literature to academic preciosity, in the last instance reveals itself as an ironic antidote to Romantic identification. This trend is confirmed by the remarkable increase in the number of quotations from the first edition (1876 to the second publication in volume form in 1883.

    The MiniBooNE Collaboration reports a search for νμ and ν¯μ disappearance in the Δm2 region of 0.5-40eV2. These measurements are important for constraining models with extra types of neutrinos, extra dimensions, and CPT violation. Fits to the shape of the νμ and ν¯μ energy spectra reveal no evidence for disappearance at the 90% confidence level (C.L.) in either mode. The test of ν¯μ disappearance probes a region below Δm2=40eV2 never explored before.

    Photomultiplier tubes are the main detector component for many neutrino physics experiments. A signal's position and angle relative to a photomultiplier tube's axis can affect tube performance; understanding this effect is important for analyzing and modeling tube behavior in large neutrino detectors. Collaborators on the MiniBooNE experiment at Fermilab developed a light-tight test enclosure to measure photomultiplier output as signal position and angle were varied. Results show a decrease in "signal visibility," or relative quantum efficiency, of roughly 15%.

    The effects of unfolding technique on neutron spectra measured with a miniature NE-213 spectrometer are investigated. The codes used were FORIST, FERDOR and RADAK, a differential code FLYSPEC and one developed by the authors based on Neural Networks. The characteristics required of experimental test spectra were that they be structured, well known and have a significant component above 10 MeV. Four different test spectra were employed. It is found that all the codes performed well with the test spectra used, producing generally consistent results.

    Two-proton decay of the unbound T{sub z} =-2 nucleus {sup 16}Ne, produced in one-neutron knockout from a 500 MeV/u {sup 17}Ne beam, has been studied at GSI. The ground state, at a resonance energy 1.388(15) MeV, (Γ = 0.082(15) MeV) above the {sup 14}O+p+p threshold, and two narrow resonances at E{sub r} = 3.220(46) MeV and 7.57(6) MeV have been investigated. A comparison of the energy difference between the first excited 2{sup +} state and the 0{sup +} ground state in {sup 16}Ne with its mirror nucleus {sup 16}C reveals a small Thomas-Ehrman shift (TES) of +70(46) keV. A trend of the TES for the T = 2 quintet is obtained by completing the known data with a prediction for {sup 16}F obtained from an IMME analysis. The decay mechanisms of the observed three resonances were revealed from an analysis of the energy and angular correlations of the {sup 14}O+p+p decay products. The ground state decay can be considered as a genuine three-body (democratic) mode and the excited states decay sequentially via states in the intermediate nucleus {sup 15}F, the 3.22 MeV state predominantly via the {sup 15}F ground-state resonance, while the 7.57 MeV state decays via the 5/2{sup +} resonance in {sup 15}F at 2.8 MeV above the {sup 14}O+p+p threshold. Further, from an analysis of angular correlations, the spin-parity of the 7.57 MeV state has been determined as I{sup π} = 2{sup +} and assigned as the third 2{sup +} state in {sup 16}Ne based on a comparison with {sup 16}C.

    Neon emission lines are good indicators of high-excitation regions close to a young stellar system because of their high ionization potentials and large critical densities. We have discovered [Ne III] λ3869 emission from the microjets of Sz 102, a low-mass young star in Lupus III. Spectroastrometric analyses of two-dimensional [Ne III] spectra obtained from archival high-dispersion (R ≈ 33, 000) Very Large Telescope/UVES data suggest that the emission consists of two velocity components spatially separated by ∼0.''3, or a projected distance of ∼60 AU. The stronger redshifted component is centered at ∼ + 21 km s{sup –1} with a line width of ∼140 km s{sup –1}, and the weaker blueshifted component at ∼ – 90 km s{sup –1} with a line width of ∼190 km s{sup –1}. The two components trace velocity centroids of the known microjets and show large line widths that extend across the systemic velocity, suggesting their potential origins in wide-angle winds that may eventually collimate into jets. Optical line ratios indicate that the microjets are hot (T ≲ 1.6 × 10{sup 4} K) and ionized (n{sub e} ≳ 5.7 × 10{sup 4} cm{sup –3}). The blueshifted component has ∼13% higher temperature and ∼46% higher electron density than the redshifted counterpart, forming a system of an asymmetric pair of jets. The detection of the [Ne III] λ3869 line with the distinct velocity profile suggests that the emission originates in flows that may have been strongly ionized by deeply embedded hard X-ray sources, most likely generated by magnetic processes. The discovery of [Ne III] λ3869 emission along with other optical forbidden lines from Sz 102 supports the picture of wide-angle winds surrounding magnetic loops in the close vicinity of the young star. Future high-sensitivity X-ray imaging and high angular-resolution optical spectroscopy may help confirm the picture proposed.

    The solubilities of Ne, Ar, Kr, and Xe gases were measured in natural samples of anorthite, diopside, forsterite, spinel, and synthetic basaltic melts, the samples which represent equilibrium pairs in the Fo-An-Di-SiO2 system. Results show that, in natural minerals, the solubilities of these gases increase with increasing atomic number. In contrast, the solubilities of noble gases in the synthetic basaltic melts decreased with increasing atomic number. The partition coefficients increased with increasing atomic number for all mineral/melt pairs.

    Renal failure is one of the main causes of death in patients with Fabry disease (FD). Due to the low prevalence of FD, delayed diagnosis and misdiagnosis, often the correct diagnosis is made when organ damage is already present. Early recognition of the disease would allow the prevention of severe complications and the premature death of patients with FD. We present here the PrEFiNE project, which includes a wide spectrum of activities with the aim of improve knowledge and diagnosis of FD. The project is sponsored by Shire Iberia (http://shireiberica.com/) From January 2016 to the end of 2017 several activities will be carried out, starting with a survey to evaluate current FD knowledge among nephrologists; in addition some studies to assess prevalence of this disease will be performed. One study will include patients receiving dialysis, another study will cover kidney transplant patients, and a pilot study in chronic kidney disease in stage 3-5 predialysis. Also planned is a pharmacoeconomic study to focus on burden of FD. At the same time medical education activities will be conducted both on line and on site. Plan for dissemination will include medical publications and diffusion to media. PrEFiNE Project will finish with the publication of a compilation book on FD in Nephrology including all planned activities and proposing recommendations based on results and detected unmet needs. PrEfiNE Plan will be coordinated by severa scientific committees, one at national level and 10 other regionals comittees, tha will be responsible to ensure the maximum scientific quality of proposed activities. An advisory board will supervise the project. PrEfiNE project will evaluate an action plan focused on improving FD knowledge to make necessary recommendations for an early recognition of the disease. In addition will generate a plan to improve previously undetected needs. Copyright © 2016 Sociedad Española de Nefrología. Published by Elsevier España, S.L.U. All rights

    Pure multiple ionization cross sections of Ne by B{sup 2+} projectiles have been measured in the energy range of 0.75 to 4.0 MeV and calculated using the continuum distorted wave-eikonal initial state approximation. The experiment and calculations show that the ionization cross sections by B{sup 2+}, principally for the production of highly charged recoils, is strongly enhanced when compared to the bare projectile with the same charge state, He{sup 2+}, at the same velocities.

A CO{sub 2} laser is utilized as the main probe beams, while copropagating visible HeNe laser beams are mainly sensitive to vibration. Density measurements in C-2 plasmas have shown that this is a reliable turn-key system. The maximum residual phase noise after vibration compensation is less than {+-}5 deg., corresponding to a line integral density of 3x10{sup 18} m{sup -2}. The time resolution for routine operation is 2 {mu}s.

    Accurate understanding of the subsurface production rate of the radionuclide 39Ar is necessary for argon dating techniques and noble gas geochemistry of the shallow and the deep Earth, and is also of interest to the WIMP dark matter experimental particle physics community. Our new calculations of subsurface production of neutrons, 21Ne , and 39Ar take advantage of the state-of-the-art reliable tools of nuclear physics to obtain reaction cross sections and spectra (TALYS) and to evaluate neutron propagation in rock (MCNP6). We discuss our method and results in relation to previous studies and show the relative importance of various neutron, 21Ne , and 39Ar nucleogenic production channels. Uncertainty in nuclear reaction cross sections, which is the major contributor to overall calculation uncertainty, is estimated from variability in existing experimental and library data. Depending on selected rock composition, on the order of 107-1010 α particles are produced in one kilogram of rock per year (order of 1-103 kg-1 s-1); the number of produced neutrons is lower by ∼ 6 orders of magnitude, 21Ne production rate drops by an additional factor of 15-20, and another one order of magnitude or more is dropped in production of 39Ar. Our calculation yields a nucleogenic 21Ne /4He production ratio of (4.6 ± 0.6) ×10-8 in Continental Crust and (4.2 ± 0.5) ×10-8 in Oceanic Crust and Depleted Mantle. Calculated 39Ar production rates span a great range from 29 ± 9 atoms kg-rock-1 yr-1 in the K-Th-U-enriched Upper Continental Crust to (2.6 ± 0.8) × 10-4 atoms kg-rock-1 yr-1 in Depleted Upper Mantle. Nucleogenic 39Ar production exceeds the cosmogenic production below ∼700 m depth and thus, affects radiometric ages of groundwater. The 39Ar chronometer, which fills in a gap between 3H and 14C , is particularly important given the need to tap deep reservoirs of ancient drinking water.

    Conditions in which (carbazolylene-pyrrolylene) random copolymers could be synthetized directly by chemical oxidation by FeCl3 were studied. A substantial amount of soluble copolymers is obtained after work-up in the conditions corresponding to carbazole/pyrrole/2 FeCl3 molar proportions. An important fraction of polypyrrole was obtained beside a fraction of species soluble in ethanol (carbazole and dimer) and an other fraction of products soluble in water (pyrrole accompanied by the first terms of the oligomeric series). Soluble copolymers were characterized by means of SEC, NMR and UV-Visible spectroscopies. Cyclic voltammetry analysis disclosed that these copolymers exhibit both the carbazolic and the pyrrolic features. Les conditions dans lesquelles des copolymères statistiques (carbazo lylène-pyrrolylène) pouvaient être synthétisés directement par oxydation chimique par FeCl3 ont été étudiées. Des quantités substantielles de copolymères solubles en milieu organique sont obtenues par extraction lorsque les proportions molaires en réactifs carbazole/pyrrole/2 FeCl3 sont utilisées. Une fraction importante de polypyrrole est obtenue à côté d'une fraction d'espèces solubles dans l'éthanol (carbazole et son dimère) et d'une fraction de produits solubles dans l'eau (pyrrole et les premiers termes oligomères). Les copolymères solubles ont été caractérisés par CES, spectroscopies RMN et UV-Visible. L'analyse voltampérométrique de ces matériaux révèle qu'ils possèdent à la fois les caractéristiques des entités carbazolylènes et celles des entités pyrrolylènes.

  3. He-Ne laser preillumination improves the resistance of tall fescue (Festuca arundinacea Schreb.) seedlings to high saline conditions.

    2015-07-01

    In this paper, we explored the protective effect and physiochemical mechanism of He-Ne laser preillumination in enhancement of tall fescue seedlings tolerance to high salt stress. The results showed that salt stress greatly reduced plant growth, plant height, biomass, leaf development, ascorbate acid (AsA) and glutathione (GSH) concentration, the enzymatic activities, and gene expression levels of antioxidant enzymes such as catalase (CAT) and glutathione reductase (GR) and enhanced hydrogen peroxide (H2O2) content, superoxide radical (O2 (·-)) generation rates, membrane lipid peroxidation, relative electrolyte leakage, the enzymatic activities, and gene expression levels of superoxide dismutase (SOD), ascorbate peroxidase (APX), and peroxidase (POD), compared with controls. However, He-Ne laser preillumination significantly reversed plant growth retardation, biomass loss, and leaves development decay induced by salt stress. And the values of the physiochemical parameters observed in salt-stressed plants were partially reverted or further increased by He-Ne laser. Salt stress had no obvious effect on the transcriptional activity of phytochromeB, whereas He-Ne laser markedly enhanced its transcriptional level. Preillumination with white fluorescent lamps (W), red light (RL) of the same wavelength, or RL, then far-red light (FRL) had not alleviated the inhibitory effect of salt stress on plant growth and antioxidant enzymes activities, suggesting that the effect of He-Ne laser on improved salt tolerance was most likely attributed to the induction of phytochromeB transcription activities by the laser preillumination, but not RL, FRL or other light sources. In addition, we also utilized sodium nitroprusside (SNP) as NO donor to pre-treat tall fescue seedlings at the same conditions, and further evaluated the differences of physiological effects between He-Ne laser and NO in increasing salt resistance of tall fescue. Taken together, our data illustrated that He-Ne

    In this paper we present the experimental results for the mobility, K0, of ions in neon-carbon dioxide (Ne-CO2) and carbon dioxide-nitrogen (CO2-N2) gaseous mixtures for total pressures ranging from 8–12 Torr, reduced electric fields in the 10–25 Td range, at room temperature. Regarding the Ne-CO2 mixture only one peak was observed for CO2 concentrations above 25%, which has been identified as an ion originated in CO2, while below 25% of CO2 a second-small peak appears at the left side of the main peak, which has been attributed to impurities. The mobility values for the main peak range between 3.51 ± 0.05 and 1.07 ± 0.01 cm2V−1s−1 in the 10%-99% interval of CO2, and from 4.61 ± 0.19 to 3.00 ± 0.09 cm2V−1s−1 for the second peak observed (10%–25% of CO2). For the CO2-N2, the time-of-arrival spectra displayed only one peak for CO2 concentrations above 10%, which was attributed to ions originated in CO2, namely CO2+(CO2), with a second peak appearing for CO2 concentrations below 10%.

    The aim of this study is to analize the influence of wind (speed and direction) on the daily airborne pollen counts recorded in Catalonia (NE Iberian Peninsula) of 21 pollen taxa recorded at 6 aerobiological stations: Barcelona, Bellaterra, Girona, Lleida Manresa, and Tarragona for the period 2004-2014. The taxa studied are Alnus, Betula, Castanea, Cupressaceae, Fagus, Fraxinus, Olea, Pinus, Platanus, total Quercus, Quercus deciduous type, Quercus evergreen type, Ulmus, Corylus, Pistacia, Artemisia, Chenopodiaceae/Amaranthaceae, Plantago, Poaceae, Polygonaceae, and Urticaceae. The mean daily wind direction was divided into 8 sectors: N, NE, E, SE, S, SW, W and NW. For each sector, the correlation between the daily pollen concentrations and wind speed using Spearman's rank correlation coefficient was computed and compared with the wind rose charts. The results showed that Tarragona was the station with more significant correlations followed by Bellaterra, Lleida and Manresa. On the other hand, Artemisia was the most correlated taxon with mainly negative values, and Fagus was the least. The W wind direction showed the largest number of significant correlations, mostly positive, while the N direction was the least and negatively correlated.

    Full Text Available The (J,T=(1,1 parity doublet in 20Ne at 11.26 MeV is a good candidate to study parity violation in nuclei. However, its energy splitting is known with insufficient accuracy for quantitative estimates of parity violating effects. To improve on this unsatisfactory situation, nuclear resonance fluorescence experiments using linearly and circularly polarized γ-ray beams were used to determine the energy difference of the parity doublet ΔE=E(1−−E(1+=−3.2(±0.7stat(−1.2+0.6sys keV and the ratio of their integrated cross sections Is,0(+/Is,0(−=29(±3stat(−7+14sys. Shell-model calculations predict a parity-violating matrix element having a value in the range 0.46–0.83 eV for the parity doublet. The small energy difference of the parity doublet makes 20Ne an excellent candidate to study parity violation in nuclear excitations.

    A study has been made of the modification of the wettability and the surface potential of polystyrene by ion bombardment and implantation. Substrates used were polystyrene (PS) dishes. Ne bombardment and Na ion implantation were performed at energies of 50 and 150 keV with fluences between 1 {times} 10{sup 14} to 1 {times} 10{sup 17} ions/cm{sup 2}. The surface potential was examined by measurements of {zeta}-potential and the wettability was examined by the contact angle of water. The contact angle of water and the {zeta}-potential are found to change, depending on ion species and fluences. Two kinds of relationships between the contact angle of water and the {zeta}-potential are found, classified by region A and region B. From XPS results, region A means that PS surfaces modified by radiation effects of Ne-bombardment or Na-implantation have new functional groups and amorphous carbon. In region B, Na implanted PS surfaces with a high fluence show not only new functional groups and amorphous carbon but also Na atoms with chemical bonding states.

    We investigate to what extent {sup 18}Ne can be descibed as a three-body system made of an inert {sup 16}O core and two protons. We compare to experimental data and occasionally to shell model results. We obtain three-body wave functions with the hyperspherical adiabatic expansion method. We study the spectrum of {sup 18}Ne, the structure of the different states and the predominant transition strengths. Two 0{sup +}, two 2{sup +}, and one 4{sup +} bound states are found where they are all known experimentally. Also one 3{sup +} close to threshold is found and several negative-parity states, 1{sup -}, 3{sup -}, 0{sup -}, 2{sup -}, most of them bound with respect to the {sup 16}O excited 3{sup -} state. The structures are extracted as partial-wave components, as spatial sizes of matter and charge, and as probability distributions. Electromagnetic decay rates are calculated for these states. The dominating decay mode for the bound states is E2 and occasionally also M1. (orig.)

  11. Sembène's Progeny: A New Trend in the Senegalese Novel

    Full Text Available The growth of the Nouvelles Editions Africaines in Senegal has proved favorable to the promotion of a national literature whose grass-roots inspiration is in obvious reaction against the elitist proclivities of earlier writers trained in French universities. The younger novelists follow in the footsteps of Sembène Ousmane, depicting actual living conditions among the under-privileged and usually silent majority in present-day Dakar. Recent examples are Aminata Sow Fall's La Grève des battù (1979, Moussa Ly Sangaré's Sourd-muet, je demande la parole (1978 and Mariama Bâ's Une si longue lettre (1979. Such works are designed for a local readership, which is numerous enough because Senegal has the highest rate of literacy in French of all African countries. While the clinical realism of their narrative technique is similar to Sembène's in many respects, the characteristic feature of those writers is that they do not seem to have any political axe to grind: their detached lucidity and absence of bitterness makes their image of the African megalopolis all the more impressive and depressing.

    The beta-delayed particle decay of sup 1 sup 7 Ne has been studied via proton-gamma coincidences, time-of-flight measurements and the ''ratio-cut technique'', allowing cleanly-separated proton and alpha-particle spectra to be obtained. A complete set of proton and alpha branching ratios for the decay of 14 excited states in sup 1 sup 7 F to the ground and excited states of sup 1 sup 6 O and sup 1 sup 3 N has been determined and branching ratios for the beta decay of sup 1 sup 7 Ne to these states have been deduced. From the branching ratios, f sub A t values and reduced Gamow-Teller matrix elements were calculated; no indication of isospin mixing in the isobaric analog state in sup 1 sup 7 F was observed. From the measurement of proton-gamma angular correlations, combined with the selection rules for an allowed beta decay, we obtain J suppi=((1)/(2)) sup - for states at 8.436 and 9.450 MeV and ((3)/(2)) sup - for the state at 10.030 MeV in sup 1 sup 7 F.

    KM3NeT-Italy is an INFN project that will develop the central part of a submarine cubic-kilometer neutrino telescope in the Ionian Sea, at about 80 km from the Sicilian coast (Italy). It will use hundreds of distributed optical modules to measure the Cherenkov light emitted by high-energy muons, whose signal-to-noise ratio is quite disfavoured. In this contribution the Trigger and Data Acquisition System (TriDAS) developed for the KM3NeT-Italy detector is presented. The “all data to shore” approach is adopted to reduce the complexity of the submarine detector: at the shore station the TriDAS collects, processes and filters all the data coming from the detector, storing triggered events to a permanent storage for subsequent analysis. Due to the large optical background in the sea from 40K decays and bioluminescence, the throughput from the sea can range up to 30 Gbps. This puts strong constraints on the performances of the TriDAS processes and the related network infrastructure.

  14. Benefit of the NeQuick Galileo Version in GNSS Single-Point Positioning

    Full Text Available The GNSS measurements are strongly affected by ionospheric effects, due to the signal propagation through ionosphere; these effects could severely degrade the position; hence, a model to limit or remove the ionospheric error is necessary. The use of several techniques (DGPS, SBAS, and GBAS reduces the ionospheric effect, but implies the use of expensive devices and/or complex architectures necessary to meet strong requirements in terms of accuracy and reliability for safety critical application. The cheapest and most widespread GNSS devices are single frequency stand-alone receivers able to partially correct this kind of error using suitable models. These algorithms compute the ionospheric delay starting from ionospheric model, which uses parameters broadcast within the navigation messages. NeQuick is a three-dimensional and time-dependent ionospheric model adopted by Galileo, the European GNSS, and developed by International Centre for Theoretical Physics (ICTP together with Institute for Geophysics, Astrophysics, and Meteorology of the University of Graz. The aim of this paper is the performance assessment in single point positioning of the NeQuick Galileo version provided by ESA and the comparison with respect to the Klobuchar model used for GPS; the analysis is performed in position domain and the errors are examined in terms of RMS and maximum error for the horizontal and vertical components. A deep analysis is also provided for the application of the exanimated model in the first possible Galileo only position fix.

    Full Text Available The stingless bee Melipona quinquefasciata is not included among the nine bee species of Melipona described in literature of NE Brazil. However, reports of some farmers raised suspicion on the occurrence of M. quinquefasciata in the state of Ceará, in NE Brazil. Investigations were carried out from July 1997 to September 2000, by means of trips to the areas of probable occurrence of this bee species. Results confirmed the presence of M. quinquefasciata in Ceará and determined its habitat along the chapada do Araripe (Araripe plateau and all extension of planalto da Ibiapaba (Ibiapaba plateau, in altitudes between 600 and 900 m. Melipona quinquefasciata lives in the phytocoenosis of cerrado (Brazilian savanna, cerradão (savanna forest and carrasco (montane deciduous shrub vegetation on the top of Araripe plateau, and only carrasco in the Ibiapaba plateau. Due to pressures caused by reduction of the area covered with native vegetation, large use of agrochemicals in anthropic areas and generalised predatory hunting of honey and beeswax, M. quinquefasciata is in risk of disappearing from the ecosystems of Araripe and Ibiapaba plateaus within a few years.

    The proliferation of liquid argon time projection chamber detectors makes the characterization of the dielectric properties of liquid argon a critical task. To improve understanding of these properties, a systematic study of the breakdown electric field in liquid argon was conducted using a dedicated cryostat connected to the MicroBooNE cryogenic system at Fermilab. An electrode sphere-plate geometry was implemented using spheres with diameters of 1.3 mm, 5.0 mm, and 76 mm. The MicroBooNE cryogenic system allowed measurements to be taken at a variety of electronegative contamination levels ranging from a few parts-per-million to tens of parts-per-trillion. The cathode-anode distance was varied from 0.1 mm to 2.5 cm. The results demonstrate a geometric dependence of the electric field strength at breakdown. This study is the first time that the dependence of the breakdown field on stressed cathode area has been shown for liquid argon.

    The present study aims to assess the tectonic activity in the Erin basin (NE Kashmir) on the basis of several relevant geomorphic indices and field observations. We use Digital Elevation Model (SRTM) and Survey of India (SoI) topographic maps in GIS environment to compute the geomorphic indices. The indices i.e., convex hypsometric curve, high hypsometric integral value (Hi > 0.5), low basin elongation ratio (Eb = 0.17), low mountain front sinuosity values (Smf = 1.08 average), low valley floor width ratios (Vf T factor (AF 4) suggest that the area is tectonically active. Moreover, prominent irregularities (knickpoints/knickzones) along longitudinal profile of the Erin River even in homogenous resistant lithology (Panjal trap) and anomalous stream gradient index (SL) values reflect that the Erin basin is dissected by two faults (EF-1 and EF-2) with NNW-SSE and SSW-NNE trends respectively. The results of this preliminary study further substantiate the recent GPS studies, which argue that the maximum strain is accumulating in the NE part of the Kashmir Himalaya.

    A new species of structurally preserved fern rhizome, Ashicaulis plumites (Osmundaceae, Filicales), is described from the Middle Jurassic Tiaojishan Formation in western Liaoning Province, NE China. The new species is characterized by a peculiar sclerenchyma mass in the petiolar vascular bundle concavity. This sclerenchyma mass varies from a linear-shape to a mushroom-like shape with a remarkable outward protuberance, which distinguishes the present new species from other Ashicaulis species. Such a protuberance is very rare among osmundaceous ferns, and should represent a unique type for sclerenchymatous tissue in the osmundaceous vascular bundle concavity. Recognition of the peculiar structure of this new fossil species enriches anatomical diversity of permineralized osmundaceous ferns, indicating that the family Osmundaceae might have experienced a remarkable diversification during the Middle Jurassic in NE China. The new species show anatomical similarities to Osmunda pluma Miller from the Palaeocene of North America. The occurrence of A. plumites in the Middle Jurassic of China provides a new clue for understanding the evolution of some members of the living subgenus Osmunda.

    In this work we present a method to evaluate the neutron response function of an NE213 liquid scintillator. This method is particularly useful when the proton light yield function of the detector has not been measured, since it is based on a proton light yield function taken from literature, MCNPX simulations, measurements of gamma-rays from a calibration source and measurements of neutrons from fusion experiments with ohmic plasmas. The inclusion of the latter improves the description of the proton light yield function in the energy range of interest (around 2.46 MeV). We apply this method to an NE213 detector installed at JET, inside the radiation shielding of the magnetic proton recoil (MPRu) spectrometer, and present the results from the calibration along with some examples of application of the response function to perform neutron emission spectroscopy (NES) of fusion plasmas. We also investigate how the choice of the proton light yield function affects the NES analysis, finding that the result does not change significantly. This points to the fact that the method for the evaluation of the neutron response function is robust and gives reliable results.
