A Redshift for the First Einstein Ring, MG 1131+0456

MG 1131+0456 is a radio-selected gravitational lens, and is the first known Einstein ring. Discovered in 1988, the system consists of a bright (S74 MHz = 3.7 Jy) radio source imaged into a ring and two compact, flat-spectrum components separated by 2. ″1. The ring is optically faint (R = 23.3), rising steeply into the near- and mid-infrared (K = 17.8; W2 = 13.4). The system has been intensively studied in the intervening years, including high-resolution radio imaging, radio monitoring, and near-infrared imaging with Hubble and Keck. The lensing galaxy is at zl = 0.844. However, to date, no spectroscopic redshift had been reported for the lensed source. Using archival Keck data from 1997, we report the robust detection of a single narrow emission line at 5438 Å, which we associate with C iii] λ1909 Å from a type-2 quasar at zs = 1.849. Support for this redshift identification comes from weaker emission associated with C iv λ1549 Å and He ii λ1640 Å, typical of type-2 quasars, as well as the lack of emission lines in archival near-infrared Keck spectroscopy. We also present, for the first time, Cycle 1 Chandra observations of MG 1131+0456, which clearly resolves into two point sources with a combined flux of ∼10−13 erg cm−2 s−1 and a best-fit column density of ∼3 × 1022 cm−2. We suggest a new method to identify candidate lensed active galactic nuclei from low-resolution X-ray surveys such as eROSITA by targeting sources that have anomalously high X-ray luminosity given their mid-infrared luminosity.
Population characteristics and biological reference point estimates for two carangid fishes, Megalaspis cordyla and Scomberoides tol, in the northern Arabian Sea coast of Pakistan.

Torpedo trevally, Megalaspis cordyla and needle scaled queenfish, Scomberoides tol are important fishery resource in the northern Arabian Sea coast of Pakistan. This study on population characteristics and dynamics of both fishes will provide data for developing strategy for its conservation. Fish were sampled from commercial vessels operated in the Pakistan coasts between July 2013 and June 2014. The samples included 293 trevally scad, M. cordyla, and 353 needle scaled queenfish, S. tol. The sex ratio of M. cordyla was female biased with 175 females (59.73%) and 118 males (40.27%), this sex difference was not statistically significant (χ2=11.088, df=1, P= <0.05). The sex ratio of S. tol was also female biased with 222 females (62.9%) and 131 males (37.1%) sampled, but this difference was also not statistically significant (χ2=23.46, df=1, P= <0.05). von Bertalanffy growth function estimated for M. cordyla was Lt= 48.3TLcm [1–e – 0.73(t – 0.148)] and for S. tol Lt = 70.3TLcm [1 – e – 0.37 (t – 0.152)]. The natural, fishing and total mortalities were estimated for M. cordyla at 1.23, 1.38, 2.62 and for S. tol 0.71, 1.86, 2.58. The biological reference points (BRP) Fopt, Flimit were estimated to determine appropriate management measures for sustainable utilization of these species. Biological reference points estimates and current catch statistics indicates that these stocks have been fished below the level that would support MSY.
Physical principles of heat pipes

Heat pipes are used whenever high rates of heat transfer or the control or conversion of heat flows are required. This book covers the physical principles of operation of heat pipes and choice of working fluid related to temperature range. The authors demonstrate how performance is limited by capillary pumping action in the wick together with impedance to liquid and vapor flow between the evaporator and condenser, sonic conditions, entrainment, evaporation and condensation rates.
Effect of Temperature on Reproductive Hormones and Egg Quality in the Native Thai Chicken

Environmental influence on the avian reproductive system is well recognised. This study investigates the effects of ambient temperature on egg quality in the native Thai Chicken (Gallus domesticus). Effects on prolactin (PRL) and ovarian steroids in chickens housed under different temperatures were also elucidated. Sixty female chickens were divided into four groups. Groups 1, 2, and 3 were reared under controlled temperatures of 35±2 °C, 31±2 °C, and 27±2 °C, respectively. Group 4 was reared under an uncontrolled natural temperature (approximately 27 °C). Blood samples were collected from each chicken once a week for 11 weeks, and plasma PRL, oestradiol (E), progesterone (P), and testosterone (T) levels were determined utilising enzyme-linked immunosorbent assays. The results revealed that E levels were significantly higher in chickens reared under low ambient temperature (27 °C) when compared with those exposed to 31 °C and 35 °C. No significant differences in PRL, P, and T levels were observed. Egg quality was affected by high ambient temperature. Eggshell thickness of chickens housed at 35 °C was thinner than those of other groups. These results indicate that changes in ambient temperature affect circulating levels of E but not PRL, P, and T. Thermally-stressed environments with high temperatures therefore impact egg quality in the native Thai chicken by reducing eggshell thickness.
Plant parasitic nematodes occurrence and genetic diversity of banana cultivars grown in Tanzania

The genetic diversity of bananas (Musa spp.), one of the most economically important crops in Tanzania, is underestimated with scarce reports available. In addition, cultivation of banana is severely constrained by plant parasitic nematodes (PPN). We assessed genetic diversity and population structure of 159 banana varieties from four agro-ecological zones (Northern, Southern highlands, Lake and Zanzibar islands) of Tanzania using 20 SSR markers analysed with UPGMA method. We also, assessed the PPN occurrence through isolation and counting of PPN from each banana genotype where leaf samples were collected. SSR primer pairs were polymorphic; and generated 63 distinct reproducible bands. The polymorphic information content values of each SSR marker ranged from 0.50 to 0.75 indicating high level of genetic diversity among banana varieties. The 159 banana varieties were grouped into two clusters: A and B, based on UPGMA cluster and population structure analysis. A total of 128 independent and 31 overlapping genotypes were identified. Higher kinship among genotypes was observed in cluster A compared with cluster B. Some of the clusters in A and B genotypes showed high genetic distance. The most prevalent and abundant nematode species was Pratylenchus goodeyi with a mean count of 63%, followed by Radopholus similis (31%) and P. coffeae (6%). The results from this study provides a foundation for understanding genetic variability of bananas existing in Tanzania and PPN occurrence that will be valuable information for breeding disease and pest-resistant bananas with high yield traits.
The Effects of Organizational Socialization Tactics on Newcomer Job Satisfaction and Engagement: Does Core Self-Evaluation Important?

One hundred and fifty-nine new workers in the government sector in Aceh Besar District were sampled to investigate whether their job satisfaction and engagement was influenced by organizational socialization tactics. Core self-evaluation is considered an important factor for newcomers who interact between organizational socialization tactics towards the outputs who were investigated in this study. Primary research data obtained from the results of questionnaires distributed to respondents who previously we have set. Structural Equation Modeling (SEM) supported by the AMOS 24 program is used to produce an accurate analysis of the primary data of this study. Based on the results of the analyzed data it was found that job satisfaction and work engagement of newcomers within the government sector organization in Aceh Besar District were influenced by factors of organizational socialization tactics in the organization itself. In addition, the results of the investigation data analysis also found that the core self-evaluation factor is important to be taken into account by newcomers when entering the organization that is now observed. Whether the results of this investigation in other places experienced the same thing, also discussed.
Intervening Effect of Back up Generation on the Relationship between Electric Power Outage Dynamics and Financial Performance of Manufacturing Firms in Kenya

: Most past literature on the correlational link between electric power outage dynamics and performance of manufacturing firms in both developed and developing economies has portrayed dissimilar conceptual debate amongst scholars with little focus on the intervening role played by investment in back up generation. This study aimed at assessing the effect of investment in back up generation on the relationship between electric power outage dynamics and performance of manufacturing firms in Kenya. Positivism philosophical point of view and descriptive survey research design was utilized. It was hypothesized that the relationship between electric power outage dynamics and performance of manufacturing firms in Kenya is not significantly mediated by investment in back up generation, which was tested at 95% confidence level. A population of 447 firms whose main area of focus is manufacturing in Kenya and were also members of Kenya Manufacturers Association was selected out of which a sample size of 138 firms was drawn using Kate (2006) formula and stratified random sampling methodology. Structured questionnaires were utilized to collect data which involved drop and pick approach. The research results indicate that investment in backup generation intervened the correlation between electric power outage dynamics and financial performance. This study outcome augments existing knowledge on the association amongst electric power outage dynamics; investment in back up generation, and financial performance, for it is evident that top management must be judicious in the decision on investment in back up generation in mitigating negative effects of power outage on financial performance of firms. The decisions are on whether investment in backup to address power outage challenges has positive or negative effects on firm performance, while at the same time considering the critical decision on the most optimal level of backup capacity to invest in. The study has also made an input to the academic literature arising from assimilation of two theories, namely; financial theory of investment, and transformation theory. The Kenya Association of Manufacturers (KAM) may use these research findings to guide their member firms on strategies to adopt to ensure continuous productivity and avoidance of damages due to electric power outage dynamics. to
Understanding recurrent neural network for texts using English-Korean corpora

Deep Learning is the most important key to the development of Artiﬁcial Intelligence (AI). There are several distinguishable architectures of neural networks such as MLP, CNN, and RNN. Among them, we try to understand one of the main architectures called Recurrent Neural Network (RNN) that di ﬀ ers from other networks in handling sequential data, including time series and texts. As one of the main tasks recently in Natural Language Processing (NLP), we consider Neural Machine Translation (NMT) using RNNs. We also summarize fundamental structures of the recurrent networks, and some topics of representing natural words to reasonable numeric vectors. We organize topics to understand estimation procedures from representing input source sequences to predict target translated sequences. In addition, we apply multiple translation models with Gated Recurrent Unites (GRUs) in Keras on English-Korean sentences that contain about 26,000 pairwise sequences in total from two di ﬀ erent corpora, colloquialism and news. We veriﬁed some crucial factors that inﬂuence the quality of training. We found that loss decreases with more recurrent dimensions and using bidirectional RNN in the encoder when dealing with short sequences. We also computed BLEU scores which are the main measures of the translation performance, and compared them with the score from Google Translate using the same test sentences. We sum up some di ﬃ culties when training a proper translation model as well as dealing with Korean language. The use of Keras in Python for overall tasks from processing raw texts to evaluating the translation model also allows us to include some useful functions and vocabulary libraries as well.
Étude de l'élaboration de matériaux composites PVC/Bois à partir de déchets de menuiserie : formulation, caractérisation, durabilité et recyclabilité

L’etude des parametres d’elaboration de composites PVC/bois a permis de montrer que le processus de mise en oeuvre, le taux et le type de fibres de bois influencent plus les proprietes mecaniques du materiau que les traitements de compatibilisation. Un nouvel agent de liaison a ete propose : l’acide gallique, polyphenol present dans plusieurs essences de bois. Il a permis d’augmenter nettement les proprietes mecaniques du materiau grâce a une bonne adhesion a l’interface fibre/matrice. Le renfort vegetal augmente la sensibilite du composite aux rayonnements UV et a l’eau provoquant un changement de couleur en surface et une perte des proprietes mecaniques. L’ajout de certains pigments a permis de ralentir la degradation due aux UV et l’ajout d’acide gallique, celle due a l’eau, sans toutefois les supprimer. Il a ete demontre enfin que cinq cycles de vieillissement thermo-mecanique ne modifient pas les proprietes mecaniques de ces composites : leur recyclage est possible tel quel.
Flamelet Model Application for Non-Premixed Turbulent Combustion

The current Final Report contains results of the study which was performed in Scientific Research Center 'ECOLEN' (Moscow, Russia). The study concerns the development and verification of non-expensive approach for modeling of supersonic turbulent diffusion flames based on flamelet consideration of the chemistry/turbulence interaction (FL approach). Research work included: development of the approach and CFD tests of the flamelet model for supersonic jet flames; development of the simplified procedure for solution of the flamelet equations based on partial equilibrium chemistry assumption; study of the flame ignition/extinction predictions provided by flamelet model. The performed investigation demonstrated that FL approach allowed to describe satisfactory main features of supersonic H 2/air jet flames. Model demonstrated also high capabilities for reduction of the computational expenses in CFD modeling of the supersonic flames taking into account detailed oxidation chemistry. However, some disadvantages and restrictions of the existing version of approach were found in this study. They were: (1) inaccuracy in predictions of the passive scalar statistics by our turbulence model for one of the considered test cases; and (2) applicability of the available version of the flamelet model to flames without large ignition delay distance only. Based on the results of the performed investigation, we formulated and submitted to the National Aeronautics and Space Administration our Project Proposal for the next step research directed toward further improvement of the FL approach.
Acute effect of foot orthotics on drag area and perceived comfort in cyclists affected by an anatomic asymmetry in time trial position

The aim of this study was to analyse the acute effect of biomechanical foot orthotics on drag area (ACd) and perceived comfort in elite cyclists affected by a lower limb length inequality (LLLI) in TT position. Twenty-nine cyclists performed two discontinuous incremental exercises (before and after orthopaedic correction) using their personal TT bicycle and equipment on a 250-m indoor velodrome. The ACd was unchanged in both the test group (TG) (‑0.5%, p = 0.707) and the control group (CG) (-1.4%, p = 0.276), whereas the perceived comfort was improved in the TG (+6.2%, p = 0.002) and stabilised in the CG (+0.7%, p = 0.546), after the fitting of the foot orthotics. Pelvis movements were decreased (small effect size) in the TG (-6.2%, p = 0.093, ES = 0.251), whereas they were increased (small effect size) in the CG (+5.2%, p= 0.159, ES = 0.215). TT position was slightly improved by compensating for a LLLI, as the ACd was stabilised and the level of comfort was improved. Thus, cyclists affected by a LLLI are recommended to compensate with foot orthotics in order to improve their level of comfort and consequently their performance in TT position.
Phenotypic and Genotypic Characteristics of Methicillin-Resistant Staphylococcus aureus Isolated from Dairy and Meat Products in Iran

Background: Methicillin-Resistant Staphylococcus aureus (MRSA) plays an important role in gastrointestinal diseases. The goal of this research was to determine phenotypic and genotypic characteristics of MRSA isolated from dairy and meat products in Iran. Methods: Ninety-three S. aureus isolates were prepared which had been obtained in our previous study. Antimicrobial susceptibility testing was done using disk diffusion method. The isolates were further analyzed by mecA gene detection. Staphylococcal Enterotoxins (SEs) and Toxic Shock Syndrome Toxin 1 (TSST1) were screened. Biotyping and molecular typing were done by short sequence repeats of spa and coa genes. Results: Five out of 93 S. aureus isolates (5.37%) included mecA. All five MRSA isolates were sensitive to at least six tested antibiotics and none were resistant to vancomycin. Furthermore, two isolates were multidrug resistant. Four isolates produced SEs and TSST1. Three out of 5 isolates were related to human biotype and two belonged to non-host-specific biotype. Conclusion: Presence of MRSA in dairy and meat products may be an important hygienic risk for the Iranian consumers, especially for immunocompromised people.
Functionally Coherent Transcription Factor Target Networks Illuminate Control of Epithelial Remodelling and Oncogenic Notch

Background Cell identity is governed by gene expression, regulated by Transcription Factor (TF) binding at cis-regulatory modules. Decoding the relationship TF binding patterns and the regulation of cognate target genes is nontrivial, remaining a fundamental limitation in understanding cell decision-making mechanisms. Identification of TF physical binding that is biologically ‘neutral’ is a current challenge. We studied cell identity in the context of Epithelial to Mesenchymal Transition (EMT), a cell programme fundamental for normal embryonic development that contributes to tumour progression and fibrosis. Results We developed the NetNC software for discovery of functionally coherent TF targets. NetNC was applied to analyse gene regulation by the EMT TFs Snail, Twist in early embryogenesis and also to modENCODE ‘HOT’ regions. Predicted neutral binding accounted for 50% to ≥80% of candidate target genes assigned from significant binding peaks. Novel gene functions and network modules were identified, including regulation of chromatin organisation and crosstalk with notch signalling. Orthologues of predicted TF targets discriminated breast cancer molecular subtypes and NetNC analysis predicted new gene functions; for example, evidencing networks that reshape Waddington’s landscape during EMT-like phenotype switching. Predicted invasion roles for SNX29, ATG3, UNK and IRX4 were validated using a tractable cell model. Conclusions We found extensive neutral TF binding across the nine datasets examined and showed that NetNC performs well in identifying functionally coherent targets. HOT regions had comparatively high functional coherence. Our results illuminate conserved molecular networks that regulate epithelial remodelling in development and disease, with potential implications for precision medicine.
