Structure and magnetism in synthetic pyrrhotite Fe 7 S 8 : A powder neutron-diffraction study

The relationship between structural and magnetic properties in stoichiometric pyrrhotite ${\text{Fe}}_{7}{\mathrm{S}}_{8}$ has been investigated using variable-temperature neutron-diffraction data. Below its magnetic ordering temperature, ${T}_{\mathrm{N}}=598(5)\phantom{\rule{0.3em}{0ex}}\mathrm{K}$, ${\text{Fe}}_{7}{\mathrm{S}}_{8}$ exhibits a monoclinic 4C structure, related to that of NiAs, in which fully occupied cation layers alternate with cation-deficient layers. The magnetic structure consists of ferromagnetically aligned layers, with antiferromagnetic coupling of adjacent layers. The ordered moment of $3.16(1){\ensuremath{\mu}}_{\mathrm{B}}$ at $11\phantom{\rule{0.3em}{0ex}}\mathrm{K}$ is directed at an angle of $29\ifmmode^\circ\else\textdegree\fi{}$ to the layers. The magnetic transition is accompanied by a structural transformation from the monoclinic 4C structure to a hexagonal cation-deficient NiAs structure, in which the vacancies are statistically distributed between all layers. Although the 4C structure is recovered on cooling through the magnetic transition, the resultant phase exhibits a significant degree of intralayer cation disorder.
Antibiotic Susceptibility Profile of Clinical Isolate of Carbapenem-Resistant Pseudomonas aeruginosa

Background and Objectives: Carbapenem-resistant Pseudomonas aeruginosa, are among the top tier of the list of antibiotic-resistant priority pathogens that pose the greatest threat to human health. In recent years, the rate of carbapenem resistance in Pseudomonas aeruginosa has increased worldwide and has become of great concern since it significantly restricts the therapeutic options for patients. Therefore this study was undertaken to determine the antibiotic susceptibility profile of the clinical isolate of Carbapenem-resistant Pseudomonas aeruginosa. Methodology: A total of five hundred (500) clinical samples were collected from patient’s attending Alex Ekwueme Federal University Teaching Hospital Abakaliki, Ebonyi State (AFEUTHA). The collected samples were analyzed for the presence of Pseudomonas aeruginosa using standard microbiological techniques for isolation and characterization of bacteria. Further strain confirmation was performed using VITEK 2 System. Phenotypic detection of Carbapenem-resistant Pseudomonas aeruginosa was performed using Modified Hodge testing. Antibiotic susceptibility was performed by employing Kirby-Bauer disk diffusion method and the results were interpreted using the Clinical Laboratory Standard Institute (CLSI) zone diameter breakpoints. Results: The occurrence rate of Pseudomonas aeruginosa in clinical samples accounted for 119(23.8%) consisting of a high proportion from urine sample 81(27.4%) followed by wound swabs 13(25.5%), high vaginal swabs 17(20.7) while the least occurrence rate was observed against catheter tips 5(12.8%) and sputum 3(9.4%). Modified Hodge testing revealed 31(6.2%) carbapenem-resistant Pseudomonas aeruginosa comprising of high proportion of 24(8.1%) from urine samples followed by wound swab 5(9.8%) while Carbapenem-resistant Pseudomonas aeruginosa was absent in High Vaginal Swab recording 0(0.0%). Carbapenem-resistant Pseudomonas aeruginosa isolates were highly resistant to amoxicillin-clavulanic 100%, colistin 100%, tetracycline 100%, nitrofurantoin 70.8%, aztreonam 87.5% but were susceptible to nalixidic acid 50.0 %, ofloxacin 75.0%, and ciprofloxacin 100%. Conclusion: As in-vitro susceptibility of carbapenem-resistant Pseudomonas aeruginosa isolates to ofloxacin and ciprofloxacin is known, their judicious utilization will accelerate a significant improvement in the patient's condition. As such, there is a substantial need for the evaluation of a wide spectrum and new therapies in different classes to counteract this imminent crisis of resistance among Carbapenem-resistant Pseudomonas aeruginosa.
A Simple Model of Farm Bankruptcies

We devise a simple empirical model of U.S. farm bankruptcies as a function of the lagged aggregate farm sector debt-to-asset ratio. Despite its simplicity, the model has very good explanatory power. We discuss, given the the current levels of debts and assets, the potential numbers of additional bankrupticeis that would result from shocks to farm asset values. We also present data on debt-to-asset ratios by farm size and discuss the implications of our results for different sized farms.
An efficient method for recovering Lyapunov vectors from singular vectors

Abstract Lyapunov vectors are natural generalizations of normal modes for linear disturbances to aperiodic deterministic flows and offer insights into the physical mechanisms of aperiodic flow and the maintenance of chaos. Most standard techniques for computing Lyapunov vectors produce results which are norm-dependent and lack invariance under the linearized flow (except for the leading Lyapunov vector) and these features can make computation and physical interpretation problematic. An efficient, norm-independent method for constructing the n most rapidly growing Lyapunov vectors from n − 1 leading forward and n leading backward asymptotic singular vectors is proposed. The Lyapunov vectors so constructed are invariant under the linearized flow in the sense that, once computed at one time, they are defined, in principle, for all time through the tangent linear propagator. An analogous method allows the construction of the n most rapidly decaying Lyapunov vectors from n decaying forward and n − 1 decaying backward singular vectors. This method is demonstrated using two low-order geophysical models.
Influence of feed form and probiotic levels on growth performance, carcass traits, some blood parameters and nutrients digestibility of broiler chicks

The present study aimed to evaluate the effect of feed form (pelleted versus mash diets) and probiotic levels on growth performance, carcass traits, some blood parameters and nutrients digestibility of Ross broiler chicks during 42 days experimental period. One hundred and twenty, one day old Ross broiler chicks were randomly distributed into eighth treatments. Each treatment consisted of three replicates of 5 birds each. Both mash and pellet diet groups were subdivided into four treatment groups each. Each fed form supplemented with 0, 1, 1.5 and 2 g probiotic /kg diet, respectively. The obtained data showed that at 3 and 6 weeks of age, broilers fed a pellet diet had considerably higher body weight, weight gain, feed intake, and feed conversion ratio than those fed a mash diet. The ultimate BW and BWG, FI, and FCR of the birds fed the 1g or 1.5g probiotic/kg diets were considerably greater than those fed the 2g probiotic diet and the control diet. The addition of probiotics to the food or feed form of broilers at doses of 1, 1.5, and 2 g/kg had no effect on the carcass and blood parameters. When fed a mash meal instead of a pellet diet, the dry matter and protein digestibility values improved. It can be concluded that fed pellet-diet with the supplementation of 1 and 1.5 g probiotic/kg diet improved productive performance but had no consistent effect on overall carcass traits and blood parameters of broilers chicks.
Role of Diethylentriamine Penta-Acetic Acid Renograms in Differentiation between Acute Tubular Necrosis and Acute Rejection in Early Post Allograft Renal Transplantation in A Single Tertiary Center

Background: The diagnosis of a failing renal allograft is a complex process. Radionuclide imaging is a great method that gives additional details about the perfusion and function of the transplant without harming the allograft to avoid invasive renal biopsy and its complications. Objective: The aim of the current study is the differentiation between acute renal graft rejection and acute tubular necrosis in the early post-transplant period using dynamic 99mTc-DTPA scintigraphy. Patients and methods: A retrospective study was conducted and included 56 cases suffering from acute deteriorated graft function in first year after renal transplantation. We reviewed their dynamic 99mTc-DTPA images findings which performed at time of graft dysfunction and compared with graft biopsy results as a gold standard. Results: Acute renal rejection was diagnosed in 16 cases; acute tubular necrosis was evident in 28 cases and 12 cases suffering from both elements. By analysis, the mean ages of cases of acute renal graft rejection were 29.3 (SD 9.4) years, cases of acute tubular necrosis were 30.1 (SD 8.1) years, and cases of both elements were 30.7 (SD 5.6) years old. The scintigraphic results showed perfusion and delayed tracer excretion were the most significant predictors (P-value =0.001). The sensitivity and specificity of renal scintigraphy for the detection of acute tubular necrosis (ATN) were 89.3% and 96.4%, respectively; in acute rejection (AR), were 97% and 99%. Conclusion: A non-invasive procedure with high sensitivity and specificity to distinguish between acute renal rejection and acute tubular necrosis is dynamic renal scintigraphy using 99mTc-DTPA.

Among them, 24(28.92%) had both bacterial infection with glucose.
Morpho-molecular Characterization and Phylogenetic Relationship of Tapinoma indicum Forel from Metropolitan Area

Tapinoma indicum Forel is one of the most abundant nuisance pests found in Penang Island, Malaysia. However, limited research has been done on T. indicum, especially in the molecular genetic field. This paper aims to collect T. indicum from three districts in Penang Island, Malaysia including George Town, Gelugor, Balik Pulau, characterize T. indicum based on morphological measurements and molecular characterization of T. indicum using mitochondrial cytochrome c oxidase subunits 1 (CO1) sequences and 16S ribosomal DNA (16S rDNA) sequences. The morphological measurements resulting in HL = 4.31 ± 0.12 mm, HW = 3.87 ± 0.06 mm, EL = 0.89 ± 0.05 mm, EW = 0.58 ± 0.01 mm, SL = 3.56 ± 0.08 mm, ML= 1.11 ± 0.12 mm, CI = 89.83 ± 1.17, EI = 20.59 ± 0.88 and SI = 82.95 ± 2.34. The CO1 sequences and 16S rDNA sequences of T. indicum from each population are deposited and accessible via Genbank (NCBI) database. The phylogenetic trees result in two clades with three haplotypes, but the genetic structure is not well revealed.
Students Teachers’ Self- Efficacy and Teaching Effectiveness

This study concerned to the experience of students who had completed the teaching practice as their task in university. This study aims to discuss how self-efficacy influences teaching effectiveness, specifically at initial teaching of their teaching practice. The phenomenological approach as part of qualitative research was applied to see the students’ experience during teaching practice. The sample was four students at English Department, University of Muhammadiyah, Aceh that selected purposively. The four students were interviewed pertaining to five aspects: the importance of self-efficacy, promoting students’ learning, classroom management, building self-efficacy, and teaching ability. To interpret the interview data, the Huberman’ concept was proposed. The finding revealed that the self-efficacy outlines the advantageous for student teachers who were unversed in teaching-learning process. This self-efficacy helped them to have the braveness and the eagerness in increasing the teaching ability that positively affected their teaching effectiveness.
OBSERVATIONAL CONSTRAINTS ON METHANOL PRODUCTION IN INTERSTELLAR AND PREPLANETARY ICES

Methanol (CH3OH) is thought to be an important link in the chain of chemical evolution that leads from simple diatomic interstellar molecules to complex organic species in protoplanetary disks that may be delivered to the surfaces of Earthlike planets. Previous research has shown that CH3OH forms in the interstellar medium predominantly on the surfaces of dust grains. To enhance our understanding of the conditions that lead to its efficient production, we assemble a homogenized catalog of published detections and limiting values in interstellar and preplanetary ices for both CH3OH and the other commonly observed C- and O-bearing species, H2O, CO, and CO2. We use this catalog to investigate the abundance of ice-phase CH3OH in environments ranging from dense molecular clouds to circumstellar envelopes around newly born stars of low and high mass. Results show that CH3OH production arises during the CO freezeout phase of ice-mantle growth in the clouds, after an ice layer rich in H2O and CO2 is already in place on the dust, in agreement with current astrochemical models. The abundance of solid-phase CH3OH in this environment is sufficient to account for observed gas-phase abundances when the ices are subsequently desorbed in the vicinity of embedded stars. CH3OH concentrations in the ices toward embedded stars show order-of-magnitude object-to-object variations, even in a sample restricted to stars of low mass associated with ices lacking evidence of thermal processing. We hypothesize that the efficiency of CH3OH production in dense cores and protostellar envelopes is mediated by the degree of prior CO depletion.
Association of occupational noise exposure with hypertension: A cross‐sectional study

The effects of chronic occupational noise exposure on hypertension are debated. We aimed to investigate the association between occupational noise exposure and the prevalence of hypertension. The cross‐sectional data were collected from 2017 to 2018 using occupational physical examination data from a local aircraft manufacturing enterprise in Xi'an. We categorized occupational noise exposure as high (≥85 dBA) and low noise exposure (< 85 dBA). Logistic regression analysis was performed to evaluate the association between occupational noise exposure and hypertension, and associations were further evaluated using subgroup analyses for age, sex, and body mass index (BMI). Of the 4746 participants (median age, 43 years; 73.4% men), 9.57% (454/4746) had hypertension and 32.4% (1540/4746) were exposed to high noise. Compared to the participants with low occupational exposure to noise, the adjusted odds ratio (OR) for hypertension prevalence was 1.30 (1.05–1.62) for those with high occupational noise exposure. Subgroup analyses revealed that the noise‐hypertension association only existed in young participants (OR, 1.70; 95% CI, 1.21–2.40). This study revealed a harmful association between high occupational noise exposure and hypertension in young adults. The study suggests occupational noise exposure as a target for worksite interventions to prevent hypertension.
Breakup of an electrified viscous thread with charged surfactants

The dynamics and breakup of electrified viscous jets in the presence of ionic surfactants at the interface are investigated theoretically. Axisymmetric configurations are considered and the jet is surrounded by a concentrically placed cylindrical electrode, which is held at a constant voltage potential. The annular region between the jet and the electrode is taken to be a hydrodynamically passive dielectric medium and an electric field is set up there and drives the flow, along with other physical mechanisms including capillary instability and viscous effects. The jet fluid is taken to be a symmetric electrolyte and proper modeling of the cationic and anionic species is used by considering the Nernst–Planck equations in order to find the volume charge density that influences the electric field in the jet. A positively charged insoluble surfactant is present at the interface, and its evolution, as well as the resulting value of the local surface tension coefficient, is coupled with the voltage potential at.
Redox‐metabolic reprogramming of skin in mice lacking functional Nrf2 under basal conditions and cold acclimation

Adaptive responses to environmental and physiological challenges, including exposure to low environmental temperature, require extensive structural, redox, and metabolic reprogramming. Detailed molecular mechanisms of such processes in the skin are lacking, especially the role of nuclear factor erythroid 2‐related factor 2 (Nrf2) and other closely related redox‐sensitive transcription factors Nrf1, Nrf3, and nuclear respiratory factor (NRF1). To investigate the role of Nrf2, we examined redox and metabolic responses in the skin of wild‐type (WT) mice and mice lacking functional Nrf2 (Nrf2 KO) at room (RT, 24 ± 1°C) and cold (4 ± 1°C) temperature. Our results demonstrate distinct expression profiles of major enzymes involved in antioxidant defense and key metabolic and mitochondrial pathways in the skin, depending on the functional Nrf2 and/or cold stimulus. Nrf2 KO mice at RT displayed profound alterations in redox, mitochondrial and metabolic responses, generally akin to cold‐induced skin responses in WT mice. Immunohistochemical analyses of skin cell compartments (keratinocytes, fibroblasts, hair follicle, and sebaceous gland) and spatial locations (nucleus and cytoplasm) revealed synergistic interactions between members of the Nrf transcription factor family as part of redox‐metabolic reprogramming in WT mice upon cold acclimation. In contrast, Nrf2 KO mice at RT showed loss of NRF1 expression and a compensatory activation of Nrf1/Nrf3, which was abolished upon cold, concomitant with blunted redox‐metabolic responses. These data show for the first time a novel role for Nrf2 in skin physiology in response to low environmental temperature, with important implications in human connective tissue diseases with altered thermogenic responses.
Prevalence of Congenital Toxoplasmosis and Congenital Rubella among Suspected Infants in Baghdad

Congenital toxoplasmosis (CT) and congenital rubella (CR) infections are well-known causes potentially leading to devastating consequences. This report aims to address the prevalence of each of these infections among suspected infants in a pediatric hospital in Baghdad. The study sample includes 120 blood samples of suspected infants consulting Al-Alwyia pediatric teaching hospital over one year. This report represents an extension of a previous article published in Al-Kindy College Medical Journal KCMJ about cytomegalovirus infection (CMV). Using the enzyme-linked immunosorbent assay (ELISA) method, the results show that 5.8% and 5% were positive for specific IgM antibodies for rubella and toxoplasmosis respectively. Results also show that CMV is more common than CT and CR. Although results reported one case of co-existence of IgM antibodies for both CMV and rubella, there was a significant association of negative CMV IgG and IgM results with positive rubella results; and negative rubella results with CMV IgG and IgM results. Conclusions: This short brief addressed the prevalence of CT and CR in Baghdad. A novel finding identified in this brief is the association of the prevalence of CR active infection with negative past and negative recent CMV infections, and the association of prevalence of CMV active and past infections with negative CR infection Recommendations: The study recommends increased awareness, early diagnosis and treatment for congenital infection, and consolidation of coverage of the rubella vaccine for children and girls at premarital age.
Recombination-cascade X-ray spectra of highly charged helium-like ions

It is shown that the relative intensity distribution among the X-ray spectral lines of helium-like ions from the n = 2 states produced through recombination processes such as radiative and charge transfer recombination may be given by considering in detail the radiative cascades following recombination. Model calculations are presented with predicted line ratios for Ar XVII and Fe XXV in recombination-dominated noncoronal plasmas. In particular, compared to coronal intensities, the singlet resonance line (w) should be much weaker relative to the triplet intercombination (x, y) and forbidden (z) lines, yielding large values for the ratio G = (x + y + z)/w. Accurate configuration interaction type wave functions are employed to calculate the eigenenergies, transition probabilities, and cascade coefficients. Certain relevant tokamak and astrophysical observations are discussed.
Magnetohydrodynamic Taylor vortex flows

Hydromagnetic Taylor-vortex flows of liquid metals, subjected to an axially applied magnetic field, are considered. The supercritical state of flow is treated by means of perturbation method with multiple scale expansions in time and space. Results show that the supercritical state of flow is significantly affected by the imposed magnetic field. Calculations on finite equilibrium amplitude of Taylor vortices are compared with experiment. In the case of Taylor–Couette flows between insulating cylinders, good agreement is found between theory and experiment, while, in the case of electro-magnetically driven flows between steady conducting cylinders, disagreement occurs once magnetic field effects become significant. These results are discussed.
Accuracy of fine‐needle aspiration cytopathology to differentiate malignant and benign thyroid nodules with ≥4 cm diameter: A retrospective study

Thyroid nodules (TN) are commonly present in the general population and are usually pathologically benign. An initial diagnosis with fine‐needle aspiration (FNA) cytopathology could help clinical decision‐making with fewer complications. As the previous studies suggest surgical procedures for >4 cm TNs, we aimed to investigate the accuracy of preoperative FNA cytology to predict malignancy risk in these nodules in a sample of the Iranian population.
Supporting factors for labor productivity in Indonesia

Indonesia's investment attractiveness is still weak compared to other ASEAN countries; one of the reasons is the low labor productivity. On this basis, this study aims to find out what factors are dominantly driving labor productivity in Indonesia statistically, as well as the right policy model to encourage labor productivity, bringing Indonesia a high-income country. The analytical method used in this study is panel data regression analysis, 2014 - 2018 period, covering 34 provinces in Indonesia. The study suggests that fiscal policy through general allocation fund (DAU) or transfers signifies increasing labor productivity, while special allocation fund (DAK) does not. Economic factors such as labor costs, the contribution of the agricultural sector, and economic openness can increase labor productivity, while industrial sector share has no effect. Social factors measured by the education level of general secondary schools and life expectancy (health) affect labor productivity enhancement; it is different from a vocational school. Consequently, the number of unemployed vocational school graduates is high.
