Velocity-space sensitivity of the time-of-flight neutron spectrometer at JET

The velocity-space sensitivities of fast-ion diagnostics are often described by so-called weight functions. Recently, we formulated weight functions showing the velocity-space sensitivity of the often dominant beam-target part of neutron energy spectra. These weight functions for neutron emission spectrometry (NES) are independent of the particular NES diagnostic. Here we apply these NES weight functions to the time-of-flight spectrometer TOFOR at JET. By taking the instrumental response function of TOFOR into account, we calculate time-of-flight NES weight functions that enable us to directly determine the velocity-space sensitivity of a given part of a measured time-of-flight spectrum from TOFOR

Relationship of edge localized mode burst times with divertor flux loop signal phase in JET

A phase relationship is identified between sequential edge localized modes (ELMs) occurrence times in a set of H-mode tokamak plasmas to the voltage measured in full flux azimuthal loops in the divertor region. We focus on plasmas in the Joint European Torus where a steady H-mode is sustained over several seconds, during which ELMs are observed in the Be II emission at the divertor. The ELMs analysed arise from intrinsic ELMing, in that there is no deliberate intent to control the ELMing process by external means. We use ELM timings derived from the Be II signal to perform direct time domain analysis of the full flux loop VLD2 and VLD3 signals, which provide a high cadence global measurement proportional to the voltage induced by changes in poloidal magnetic flux. Specifically, we examine how the time interval between pairs of successive ELMs is linked to the time-evolving phase of the full flux loop signals. Each ELM produces a clear early pulse in the full flux loop signals, whose peak time is used to condition our analysis. The arrival time of the following ELM, relative to this pulse, is found to fall into one of two categories: (i) prompt ELMs, which are directly paced by the initial response seen in the flux loop signals; and (ii) all other ELMs, which occur after the initial response of the full flux loop signals has decayed in amplitude. The times at which ELMs in category (ii) occur, relative to the first ELM of the pair, are clustered at times when the instantaneous phase of the full flux loop signal is close to its value at the time of the first ELM

Psychological Distress in International University Students: An Australian Study

Australia is a much sort after destination of study for many thousands of international university students. However, tertiary study brings with it many challenges that may potentially precipitate psychological distress in international students. Psychological distress may be experienced in various ways. The aim of this study was to investigate the manner in which psychological distress is manifested in international students and the factors that contribute to their psychological distress. The participants consisted of 86 international students enrolled at a Queensland university who completed a battery of nine self-report questionnaires. Results showed that obsessive-compulsiveness reflected by worry, ruminations and perfectionist tendencies was the most common symptom of psychological distress in international students. Dysfunctional coping was the only factor contributing to psychological distress. These findings have important implications for the international students with reference to the assessment of their mental health issues and the designing of suitable intervention programs

Gene Expr. Patterns

Runx2 is an essential factor for skeletogenesis and heterozygous loss causes cleidocranial dysplasia in humans and a corresponding phenotype in the mouse. Homozygous Runx2-deficient mice lack hypertrophic cartilage and bone. We compared the expression profiles of E14.5 wildtype and Runx2−/− murine embryonal humeri to identify new transcripts potentially involved in cartilage and bone development. Seventy-one differentially expressed genes were identified by two independent oligonucleotide-microarray hybridizations and quantitative RT-PCR experiments. Gene Ontology analysis demonstrated an enrichment of the differentially regulated genes in annotations to terms such as extracellular, skeletal development, and ossification. In situ hybridization on E15.5 limb sections was performed for all 71 differentially regulated genes. For 54 genes conclusive in situ hybridization results were obtained and all of them showed skeletal expression. Co-expression with Runx2 was demonstrated for 44 genes. While 41 of the 71 differentially expressed genes have a known role in bone and cartilage, we identified 21 known genes that have not yet been implicated in skeletal development and 9 entirely new transcripts. Expression in the developing skeleton was demonstrated for 21 of these genes

Widespread expression of the testis-determining gene SRY in a marsupial

Total RNA was extracted from pooled tammar fetuses and neonatal gonads and analysed for SRY expression using reverse transcription and polymerase chain reaction (RT-PCR). In the tammar, the gonadal primordium is first apparent at day 21 of the 26.5 day gestation. By day 25 the cytoplasmic:nuclear ratio in male pre-Sertoli cells is greater than in female cells, but it is not until two days post-partum that seminiferous cords are obvious with putative Leydig cells appearing in the interstitium. We initially tested for the presence of SRY transcripts from the day after the genital ridge is established (day 22 of gestation) until two days after the development of seminiferous tubules (day 4 post partum). Surprisingly, SRY expression was detected throughout this entire developmental period in male fetal tissue and in gonads from male pouch young (Fig. 1a). We therefore extended our sampling period from day 19 of gestation (early head-fold; ~20 somites) to 40 days after birth and established that in the tammar SRY is expressed from at least 6 days before the appearance of Sertoli cells until long after the immature testis has fully differentiated (Fig. 1b). Thus, expression of the tammar SRY gene does not result in immediate Sertoli cell differentiation
