Superconducting properties in single crystals of the topological nodal semimetal PbTaSe 2

We report electronic properties of superconductivity in single crystals of topological nodal-line semimetal ${\mathrm{PbTaSe}}_{2}$. Resistivity, magnetic susceptibility, and specific heat measurements were performed on high-quality single crystals. We observed large, temperature-dependent anisotropy in its upper critical field (${H}_{c2}$). The upper critical field measured for $H\ensuremath{\parallel}\phantom{\rule{0.28em}{0ex}}\mathbf{ab}$ plane shows a sudden upward feature instead of saturation at low temperatures. The specific heat measurements in magnetic fields reveal a full superconducting gap with no gapless nodes.
GROWTH AND PROPERTIES OF CARBON NANOTUBES

An experimental study of Carbon Nanotube (CNT) growth has been performed by using radio frequency plasma enhanced chemical vapour deposition with methane (CH4) as the hydrocarbon source. The experimental results have been compared towards earlier experiments and theories that exist. A study of the effect by changing parameters during thermal- and plasma- pretreatment has been conducted which have led to successful yield of vertically aligned CNTs forests. Different growth conditions have been conducted in order to see the influence of the following: Methane (CH4) flow, plasma power, growth time, temperature, methane (CH4)/ammonia (NH3) mixtures during growth, no barrier layer, thermal- versus plasma-pretreatment and oxidizing pretreatment. The conclusion from this experiment is that oxidizing pretreatment seems yields the tallest vertically aligned CNTs with the narrowest diameter.
Potential for use of passive acoustic monitoring of piranhas in the Pacaya–Samiria National Reserve in Peru

Passive acoustic monitoring (PAM) can be an effective tool in the identification of fishes and mapping of their temporal and spatial distribution patterns and thereby aids in ecosystem management in remote locations. However, to date measurements of the acoustic properties of piranha have been primarily made in aquaria on captive specimens obtained through the aquarium trade. Data on the sound production of wild piranha taken under natural field conditions would enhance PAM applications. Piranha captured as part of routine annual monitoring by Operation Wallacea within the Pacaya–Samiria National Reserve in Peru were auditioned for sound production prior to release. Auditioning was done by gently holding a fish underwater in the river near a suspended hydrophone, thus recordings included the piranha sound as well as natural ambient sound. Seventy‐nine per cent of the 129 auditioned piranha, including Pygocentrus nattereri, Serrasalmus maculatus, Serrasalmus cf. sanchezi and an unidentified Serrasalmus spp. complex, produced sounds consisting of 2 to 23 barks in a sequential series. Sound production by S. maculatus and S. cf. sanchezi are reported for the first time. Bark characteristics exhibited high variation within bark series of individual fish. Piranha could not be distinguished by single variables but did exhibit significant multivariate differences. The relationship of several variables to fish size also differed significantly among species. Measurements of within‐fish variation and bark series pattern attributes were found to be useful for discrimination of sounds among piranha species. We demonstrate that closely related species of piranha can be distinguished by their sounds under natural acoustic conditions based on multivariate analyses, suggesting that passive acoustic monitoring (PAM) can be an effective tool for ecosystem management in the Amazon. More broadly, our study also suggests (a) the need to report more detailed statistical descriptions of fish sounds, including measures of within‐fish variation, (b) the importance of describing characteristics of sound series produced by fishes in addition to those of individual sound types and (c) the need to deposit museum voucher specimens to anchor specific sounds to specific individuals.
VERT - Verminderung der Dieselemission im Tunnelbau. Ein europaeisches Verbundprojekt von SUVA, AUVA, TBG und BUWAL

Dieselmotoren sind im Tunnelbau kaum substituierbar. Die Partikelemission heutiger Motoren ist jedoch derart hoch, dass die seit 1991 gueltigen Immissionsgrenzwerte durch Belueftung allein nicht zu erzielen sind. Im Hinblick auf grosse Tunnelvorhaben in der Schweiz, in Oesterreich und in Deutschland muessen Loesungen gefunden werden, die sich moeglichst sofort und allgemein anwenden lassen. Im Rahmen des Projekts VERT wurden daher zahlreiche Massnahmen zur Nachruestung in Pruefstandsversuchen und Feldeinsaetzen untersucht. Waehrend Oxidationskatalysatoren, Abgasrueckfuehrung und der Einsatz spezieller Treibstoffe nicht empfohlen werden koennen, hat sich die Verwendung von Partikelfiltern unterschiedlicher Systeme weitgehend bewaehrt. Besondere Beachtung wurde dabei der zuverlaessigen Abscheidung von Feinpartikeln groesser als 500 mm geschenkt. VERT kommt zum Ergebnis, dass die Abgasnachbehandlung mit Partikelfiltern machbar, kostengerecht und im Feld kontrollierbar ist und dass die Immissionsziele nur damit erreicht werden koennen.

GENOSSENSOR IMPEDIMÉTRICO BASEADO EM NANORIBBONS DE GRAFENO PARA DETECÇÃO E IDENTIFICAÇÃO DE SUBTIPOS ONCOGÊNICOS DE PAPILOMA VÍRUS HUMANO

identificação subtipos oncogênicos HPV complexa e emprega diversas técnicas complementares como a captura híbrida, southernblot, hibridização in situ, PCR, entre outras. Por este motivo, construímos um genossensor impedimétrico baseado em nanoribbons (nanofitas) de grafeno capaz de detectar e identificar, rapidamente, diversos subtipos oncogênicos de papiloma vírus humano. Para isto, foi desenvolvido um método de sintetizar nanofitas de grafeno, cuja alta sensibilidade elétrica é aproveitada para servir como transdutor capaz de analisar ABSTRACT – Currently, the identification of oncogenic HPV subtypes is complex and employs several complementary techniques such as hybrid capture, southernblot, in situ hybridization, PCR, among others. For this reason, we constructed an impedimetric genossensor based on graphene nanoribbons that quickly detects and identifies several oncogenic subtypes of human papilloma virus. For this purpose, we synthesized graphene nanoribbons, whose high electrical sensitivity enhanced the transducer effect capable of analyzing genetic samples in the picogram / microliter range. The biological recognition layer was constructed with a consensus genomic sequence (MY11) employed to amplify a broad spectrum of HPV subtypes DNA. The proposed methodology can specifically detect HPV viruses and even more, group them according to their oncogenicity degree. The results show that from the complex electrochemical response, we can find the phylogenetic relationship that exists between the genomes of the different analyzed HPVs.
Mineral nutrition and yield of sorghum inoculated with microbe strains under two agroenvironments

Los inoculantes microbianos poseen gran importancia ecologica y economica en la agricultura. Se evaluo la efectividad agrobiologica de la inoculacion de cepas microbianas en sorgo (D-47) cultivado en condiciones de riego y temporal. Fueron seis cepas experimentales de hongos micorrizicos arbusculares [3 (Funneliformis mosseae), 20 (Gigaspora albida), 32 (F. mosseae), 35 (F. mosseae), 39 (F. mosseae) y 55 (Gigaspora albida)], un consorcio de bacterias promotoras de crecimiento [Pseudomonas spp. (Bacteriano 2709)] (Ba), micorriza arbuscular INIFAP (Rhizophagus intraradices) (M) y testigo fertilizado (TF), con dosis de 60-40-00 y 120-40-00, para temporal y riego, respectivamente. Se midio clorof ila (SPAD), nitrogeno (N), fosforo (P), hierro (Fe) y zinc (Zn) foliar, biomasas foliar y radical, colonizacion micorrizica y rendimiento de grano. Las cepas microbianas influyeron de forma diferente en las caracteristicas de sorgo sembrado en los agroambientes. En general se observo mejor respuesta del sorgo en la condicion de riego. El contenido de Zn, la colonizacion micorrizica y biomasa radical, no fueron influenciados por la condicion de humedad. En riego, los mayores indices de clorof ila fueron con TF y M; en la absorcion de N destacaron TF, M y las cepas 3 y 32; los mayores valores de P se observaron con la cepa 35; para Fe sobresalio la cepa 32. Asi mismo, el consorcio Bacteriano 2709 incremento el Zn, mientras que en temporal fue la cepa 39. La mayor colonizacion se registro en M y cepas 55, 39 y 35. En rendimiento de grano, las cepas 39, 3 y M, fueron competitivas con TF y superaron al resto de los tratamientos. Los resultados demostraron que la expresion del potencial de los inoculantes microbianos en la nutricion y rendimiento de sorgo, variaron en funcion a la cepa utilizada y a la condicion de riego y temporal.
The Pyrolysis of Polytetrafluoroethylene

Although teflon(PTFE) is quite stable at the normal fabrication temperature of 330 to 360, it does undergo pyrolysis if it is maintained at temperature above 360 for extended periods of time. The extent and rate of this pyrolysis increases as the temperature is raised and pressure is reduced. The pyrolysis was also carried out in the presence of copper, no significant change was observed
Epigenetic mechanisms linking psychological stress and aging-related disease

Background: Chronic psychological stress is associated with accelerated aging and increased risk for aging-related diseases, but the underlying molecular mechanisms are unclear. Results: We examined the effect of lifetime stressors on a DNA methylation-based age predictor, epigenetic clock. After controlling for blood cell-type composition and lifestyle parameters, cumulative lifetime stress, but not childhood maltreatment or current stress alone, predicted accelerated epigenetic aging in an urban, African American cohort (n = 392). This effect was primarily driven by personal life stressors, was more pronounced with advancing age, and was blunted in individuals with higher childhood abuse exposure. Hypothesizing that these epigenetic effects could be mediated by glucocorticoid signaling, we found that a high number (n = 85) of epigenetic clock CpG sites were located within glucocorticoid response elements. We further examined the functional effects of glucocorticoids on epigenetic clock CpGs in an independent sample with genome-wide DNA methylation (n = 124) and gene expression data (n = 297) before and after exposure to the glucocorticoid receptor agonist dexamethasone. Dexamethasone induced dynamic changes in methylation in 31.2 % (110/353) of these CpGs and transcription in 81.7 % (139/170) of genes neighboring epigenetic clock CpGs. Disease enrichment analysis of these dexamethasone-regulated genes showed enriched association for aging-related diseases, including coronary artery disease, arteriosclerosis, and leukemias. Conclusions: Cumulative lifetime stress may accelerate epigenetic aging, an effect that could be driven by glucocorticoid-induced epigenetic changes. These findings contribute to our understanding of mechanisms linking chronic stress with accelerated aging and heightened disease risk.
The crystal structure of CaIrO3 post-perovskite revisited

Abstract The structure of CaIrO3 post-perovskite has been determined using CAD4 and Bruker SMART diffractometers for two different crystals. In both cases the structure was solved by Direct Methods which revealed all four atoms in the asymmetric unit. Anisotropic refinement of all atoms gave (CAD4/SMART): R1 = 0.016/0.008, wR2 = 0.032/0.009. There is excellent agreement between the structure models of the two studies. However, some notable differences were found between the structures determined here and that reported by Sugahara et al., (2008): most obviously, we observe no significant anisotropic displacements for any of the atoms. Anisotropic displacement parameters for Ca, Ir and O atoms are very similar to those of their counterparts in MgSiO3 perovskite. The close similarity of the structures of the two crystals determined here using two very different diffractometers suggests that the derived model structure reported here is better-constrained and more representative of the characteristic features of CaIrO3 post-perovskite than that obtained by Sugahara et al., (2008).
BIOPROSPEKSI RHIZOBAKTERI PENGHASIL IAA (Indole Acetic Acid) DARI TANAMAN JAGUNG (Zea maysL.) DI AREA PERTANIAN SEMI ORGANIK DESA BATURKEC. GETASAN KAB. SEMARANG

Microorganisms in nature have a rich diversity and have an important role in human lives, especially in agriculture. Some types of bacteria live in the area of plant roots called rhizobacteria. Some rhizobacteria has the ability to stimulate the growth of crops such as produce IAA ( Indole Acetic Acid ). This study aims to find rhizobacteria in maize ( Zea mays L.) which has the ability to produce IAA ( Indole Acetic Acid ) that can be used as a reference in rhizobacteria resource utilization to increase agricultural production in a sustainable and environmentally friendly.This study was conducted with bacterial isolation, characterization of bacterial isolates in colony and cell morphology, The test of rhizobacteria’s ability to produce IAA ( Indole Acetic Acid ), the molecular identification of the isolates were able to produce IAA rhizobacteria and confirmatory tests.

Régulation de l'inactivation intratumorale de l'agent antinéoplasique irinotécan par un mécanisme épigénétique

UGT1A1 is the main enzyme involved in the hepatic and tumoral inactivation of SN-38, an anticancer agent used in first line treatment of metastasic colorectal cancer. UGT1A1 genetic factors determine response to irinotecan therapy. We hypothesised that an epigenetic mechanism, more specifically methylation, is involved in tumoral regulation of UGT1A1 levels. Specific CpG islands in the UGT1A1 gene are hypermethylated and linked to the repression of gene expression and to lower levels of SN-38 glucuronidation in colon tumor cells in vitro. In addition, methylation of specific CpG was linked to lower expression of UGT1A1 gene in primary colon tumors from patients. Our data support that methylation profile of the UGT1A1 gene determine SN-38 tumoral concentration and may help to predict tumoral response to irinotecan.

They answered TIDE individually accounted 30th minutes average. The results showed statistically significant difference between the numbers of words for initial modulus of the final. There were positive and statistically significant correlations between the number of words for initial and final text production with Portuguese grade to both modulus analyzed. There is validity evidences to TIDE but it is necessary further studies to corroborate these results
Eradicating Poverty among Women in Rural Agriculture: Imperative for National Development

The agricultural sector in Nigeria is an area where gender inequity, leading to women subjugation and exploitation, is very evident. In spite of the enormity of the roles played by women in various agricultural production activities, the sector is still largely regarded as a man’s world. Statistics, however, have shown that rural women, more than their male counterparts, are involved in agriculture, constituting up to 60-80 percent of the labour force. It is therefore, ironical that their contributions to agriculture and rural development are seldom noticed or rewarded. This paper investigated the relationship between gender inequality in agriculture and impoverishment of rural women and its implication for national development. Beyond identifying the causes of gender inequity, it made context-specific recommendations towards its eradication.
Structural and Dynamic Parameters Obtained from 17O NMR, EPR, and NMRD Studies of Monomeric and Dimeric Gd3+ Complexes of Interest in Magnetic Resonance Imaging: An Integrated and Theoretically Self-Consistent Approach1

We present the results of new and previously published 17O NMR, EPR, and NMRD studies of aqueous solutions of the Gd3+ octaaqua ion and the commercial MRI contrast agents [Gd(DTPA)(H2O)]2- (MAGNEVIST, Schering AG, DTPA = 1,1,4,7,7-pentakis(carboxymethyl)-1,4,7-triazaheptane), [Gd(DTPA-BMA)(H2O)] (OMNISCAN, Sanofi Nycomed, DTPA-BMA = 1,7-bis[(N-methylcarbamoyl)methyl]-1,4,7-tris(carboxymethyl)-1,4,7-triazaheptane), and [Gd(DOTA)(H2O)]- (DOTAREM, Guerbet, DOTA = 1,4,7,10-tetrakis(carboxymethyl)-1,4,7,10-tetraazacyclododecane). High-field EPR measurements at different concentrations give evidence of an intermolecular dipole−dipole electronic relaxation mechanism that has not previously been described for Gd3+ complexes. For the first time, the experimental data from the three techniques for each complex have been treated using a self-consistent theoretical model in a simultaneous multiple parameter least-squares fitting procedure. The lower quality of the fits compared to separate fits of the data for each o.
Vers un paradigme ontologique d'interprétation des images de télédétection

Le traitement de l'information doit prendre en compte l'explicitation de la connais-sance. Cela semble une evidence, mais comment integrer celle-ci dans le cycle de constitution de l'information? L'essor actuel des systemes a base de connaissance incite a formuler cette question dans la perspective de parametrer les traitements par une connaissance formalisee et partageable. En teledetection, la connaissance intervient en particulier dans l'interpretation semantique des images satellitaires. En nous appuyant sur les ontologies, nous presentons dans cet article une demarche methodologique originale. Celle-ci permet de voir sous un jour nou-veau le rapport de l'expert avec les outils de classification qu'il est possible de parametrer avec une connaissance conceptuelle formalisee en OWL. ABSTRACT. The information processing must take into consideration the knowledge elicitation. This may seem obvious, but how to integrate it in the cycle of constitution of the information? The current development of knowledge-based systems encourages to formulate this question in prospect to set processing by a formal and sharable knowledge. In remote sensing, knowledge takes place in particular in the semantic interpretation of satellite images. Leaning on onto-logies, we present in this paper an original methodological approach. This one allows to see in a new light the relationships between the expert and the classification tools which can be parametrized with a conceptual knowledge formalized in OWL.
