Magnetic structures of cubic FeGe studied by small-angle neutron scattering

The magnetic ordering of a single crystal of the cubic polymorph of FeGe has been studied by small-angle neutron scattering. The compound orders magnetically at TN=278.7 K into a long-range spiral (period approximately 683-700 AA) propagating along equivalent directions at high temperatures and along equivalent directions at low temperatures. The length of the spiral wavevector is nearly independent of temperature. The transition at TN is first order with very little hysteresis. The transition at which the direction of the spiral turns is rather sluggish. It takes place in a temperature interval of approximately 40 K and shows pronounced temperature hysteresis (T2 down arrow =211 K, T2 up arrow =245 K). Applied magnetic fields of 20-40 mT, depending on the temperature and the field direction, cause the spiral axis to turn into the direction of the applied field. As the field is further increased, the amplitude of the antiferromagnetic spiral decreases and the ferromagnetic component increases until at fields above approximately 200-300 mT cubic FeGe becomes magnetically saturated. The magnetic ordering in cubic FeGe is a Dzyaloshinskii spiral similar to the structure observed in the isostructural compound MnSi. However, in MnSi the spiral propagates along equivalent directions at all temperatures below TN=29.5 K.
Tailoring of block copolymers based on the stoichiometric control of the end‐functionality of telechelic oligomers and the utilization of large‐scale fractionation by phase fluctuation chromatography: A synthetic strategy for the preparation of end‐functionalized poly(L‐lactide)‐block‐poly(oxyethyle

An AB diblock copolymer of poly(L-lactide) (PLLA) and poly(oxyethylene) (PEG) with a cinnamate terminal in the PEG block was prepared by the copolymerization of L-lactide and partially end-modified PEG followed by fractionation. The first step was the terminal modification of PEG with cinnamoyl chloride (CC), in which the degree of cinnamoylation of the hydroxyl terminals of PEG was roughly controlled by the feed ratio of both reactants. The resultant PEG cinnamate was subjected to copolymerization with L-lactide to produce a mixture of unreacted PEG dicinnamate (C-PEG-C), the diblock copolymer (PLLA-PEG-C), and the triblock copolymer (PLLA-PEG-PLLA) corresponding to the three components of the PEG cinnamate. This mixture was separated by phase fluctuation chromatography (PFC) to obtain PLLA-PEG-C in sufficient purity. This process, involving the stoichiometric control of the terminal reaction of telechelic oligomers and the utilization of PFC for fractionation, can be an efficient method for synthesizing end-functionalized diblock copolymers from readily available telechelic oligomers. © 2000 John Wiley & Sons, Inc.

Left Ventricular Strain: A Reliable Predictor of Short-Term Outcomes in Patients with Anterior Wall Myocardial Infarction without Heart Failure

Background: Left ventricular ejection fraction (LVEF) is a key determinant in decision-making after acute myocardial infarction (MI). Little is known of its relationship with left ventricular Strain and N-Terminal fragment of pro-B-type Natriuretic Peptide (NT-pro-BNP) following acute anterior wall MI (AWMI). Materials and Methods: We conducted a prospective cohort study of patients with a diagnosis of acute AWMI and the absence of overt heart failure (HF). Assessment of LVEF, strain parameters on echocardiography was done, and NT-pro-BNP levels were obtained. Follow-up for adverse cardiac events was done for 30 days postdischarge. Correlation of LVEF and NT-pro-BNP with various strain parameters were ascertained. Results: Of the total of 50 patients of AWMI enrolled, the mean LVEF in the study was 43.46 ± 3.72%. Eleven patients (22%) had adverse events at 30 days of follow-up. Patients with adverse events had significantly higher overall peak systolic longitudinal strain (PSLS), lower mid-region peak systolic longitudinal velocity (PSLV), and basal region PSLV. A significant negative correlation was observed between LVEF and mean Peak PSLS of combined apical plus mid regions of the left ventricle (r = −0.700). Log10-NT-pro BNP also showed a strong negative correlation with overall PSLV (r = −0.792) as well as regional PSLV values of combined apical plus mid (r = −0.763) and basal segments (r = −0.748). Conclusions: In patients with AWMI without HF, PSLS and PSLV are good predictors of adverse outcomes at 30-day follow-up. Furthermore, NT-pro BNP can also be an indirect predictor of strain parameters on echocardiography.
Polyunsaturated fatty acid status and risk of type 1 diabetes in infants and children: a systematic review and meta-analysis

Introduction The existing findings about the association between polyunsaturated fatty acid (PUFA) status (especially long-chain n-3 PUFAs) and the risk of preclinical or clinical type 1 diabetes (T1D) in children are controversial. This review aimed to evaluate the definite association. Material and methods Three databases were systematically viewed until July, 2019 to identify relevant articles, without language restriction. Any observational study or randomized controlled trial reporting the risk estimates of preclinical or clinical T1D for PUFA status in infants and children was enrolled. Regardless of the statistical heterogeneity assessed by the I2 statistic, we pooled the odds ratios (ORs), relative risks (RRs) or hazard ratios (HRs) with 95% confidence intervals (CI) through random-effects models. Results Five observational studies were enrolled in the meta-analysis. The status of n-3 PUFAs was negatively and significantly associated with the risk of preclinical, but not clinical, T1D (pooled RR = 0.85; 95% CI: 0.73–0.99) with substantial heterogeneity (I2 = 72.2%). However, no such association was found between n-6 PUFA status and the risk of preclinical or clinical T1D. Conclusions The meta-analysis suggests that n-3 PUFA might play a potential protective role in the cause of preclinical T1D, and n-3 PUFA intake may be beneficial, since the n-3 PUFA status was associated with a significant decrease in the risk of preclinical T1D in children. Nevertheless, more well-designed prospective studies are necessary to determine whether dietary or supplemental intake of specific n-3 PUFA alters the risk of preclinical T1D.
Bandgap determination and charge separation in Ag@TiO2 core shell nanoparticle films

The photocatalytic activity of TiO2 under sunlight irradiation depends on the bandgap energy. Due to the relatively low solar intensity in the UV region (<10%) and the fact that the bandgap of TiO2 is usually greater than 3 eV (below 400 nm), many attempts have been made to shift the bandgap towards lower energies. Here, we investigate the structure, chemical composition, bandgap shift and charge transfer processes of Ag@TiO2 core‐shell nanoparticle thin films by field emission scanning electron microscopy, atomic force microscopy, XPS, and UV‐Vis spectroscopy. As a solid support, Au‐coated Si wafers and Si surface covered with a native oxide were used and homogenously covered by Ag@TiO2 core‐shell nanoparticles with overall film thicknesses of 80–100 nm and size distributions between 8 and 15 nm. The shell thickness of the adsorbed Ag@TiO2 particles was estimated to be 1.5‐2.0 nm. The effect of the Ag core on the bandgap of TiO2 and photoinduced charge separation of Ag@TiO2 nanoparticle films was studied by UV‐Vis reflectance spectroscopy using the Kubelka‐Munk formalism. Films of Ag@TiO2 core‐shell nanoparticles revealed a substantially reduced bandgap of 2.75 eV (corresponding to 450 nm), and an electron charge transfer to the Ag core occurring upon UV irradiation on nonconductive surfaces. These features make Ag@TiO2 particulate films a promising candidate for photocatalytic surfaces under sunlight irradiation. Copyright © 2010 John Wiley & Sons, Ltd.
Nitrogen cycling in coastal sediment microbial communities with seasonally variable benthic nutrient fluxes

Benthic microbial communities contribute to nitrogen (N) cycling in coastal ecosystems through taxon-specific processes such as anammox, nitrification and N-fixation and community attributed pathways such as denitrification. By measuring the total (DNA-based) and active (RNAbased) surface sediment microbial community composition and the abundance and activity profiles of key N-cycling genes in a semi-enclosed embayment — Port Phillip Bay (PPB), Australia — we show that although the total relative abundance of N-cycling taxa is comparatively lower close to estuary inputs (Hobsons Bay [HB]), the capacity for this community to perform diverse N-cycling processes is comparatively higher than in sediments isolated from inputs (Central PPB [CPPB]). In HB, seasonal structuring of the sediment microbial community occurred between spring and summer, co-occurring with decreases in the activity profiles of anammox bacteria and organic carbon content. No changes were detected in the activity profiles of nitrifiers or the community-based pathway denitrification. Although no seasonal structuring of the sediment microbial community occurred in CPPB, the activity profiles of key N-cycling genes displayed comparatively higher within-site variability. These results show that despite N-cycling taxa representing a smaller fraction of the total community composition in estuary impacted sediments (HB) these microbial communities consistently engage in N-cycling processes and that seasonal instability in the composition of this community is not reflective of changes in its capacity to cycle N through coupled nitrification−denitrification but potentially via changes within the anammox community.
Event-Based Output Regulation of Boolean Control Networks With Time Delay

This brief focuses on the output regulation problem (ORP) of delayed Boolean control networks (DBCNs) under event-triggered control (ETC). Firstly, resorting to the semi-tensor product (STP) of matrices, the DBCNs model is converted into its algebraic form and the considered ORP is transformed into the set stabilization problem. Secondly, by using the matrix partitioning technique, an algorithm is proposed to find the triggering set and design the controller. Furthermore, a necessary and sufficient condition for solving the event-based ORP is provided. Lastly, a biological example is provided to illustrate the feasibility of the main results.
Fundamental Principles in Spiritualism-Based MCS

This research aimed to explore fundamental principles as the main principles in spiritualism based MCS. The fundamental principles consist of three principles as a part of ten principles in spiritualism based MCS implementation. It was an interpretive case study in a Chinese Indonesia company in Padang which sells cassava chips, a popular traditional snack from West Sumatera, Indonesia. Since fundamental principles are the main guidelines which ensoul the company, so we interviewed the owner only. To strengthen it, we also observed and analyzed some related documentations. The results showed that the company has implemented all the fundamental principles in specific ways. This research will be continued to other principles.
Clarifying Job Search Clarity: Investigating Job Search as a Self-Regulatory Process

The central role of goals in facilitating self-regulation throughout the multiple stages of job search has been recognized by scholars and models of the job search process. I argue that despite numerous calls for more research on job search goals, critical questions remain unanswered and that an explicit focus on job search goals can advance the job search literature by enhancing our understanding of job search behaviours and outcomes, while also providing actionable advice for managing the emotional and exhausting process of looking for a job. In this dissertation, I contribute to job search research by identifying gaps in the literature that can be overcome through an explicit emphasis on job search goals, empirically documenting antecedents and consequences of having clear job search goals and suggesting directions for future research. Specifically, in Chapter 2, I argue that more attention is needed on the types of goals job seekers set and outline how nuanced application of theory can close gaps in research and improve practitioners’ ability to help job seekers self-regulate effectively. In Chapters 3 and 4, I present three empirical studies (N = 367) that contribute to our understanding of how goals impact the quantity and quality of job seekers’ decisions, behaviours and outcomes by examining the downstream effects of different goal orientations (i.e., learning-approach, performance-approach, performance-avoid) and clear process and outcome goals. I conclude by discussing the theoretical and practical implications of my program of research. Clarifying Job Search Clarity iii
Spontaneous formation of a water-continuous emulsion from a w/o microemulsion

A new mechanism for spontaneous emulsification is proposed which involves inversion of a highly viscous W/O microemulsion, formed from the methyl ester of partially hydrogenated rosin containing 5 wt% of the potassium salt of partially hydrogenated rosin acid and small amounts of water, by a quiescent adjacent water phase. Inversion leads to the formation of stable, rather homogeneous O/W emulsions containing oil droplets as small as 150 nm. The proposed mechanism involves osmotically driven swelling of inverted micelles in the W/O microemulsion which remain fixed in a small volume element because of the high viscosity of the oil phase

Introduction to soil science

Soils are natural bodies made from both mineral and organic materials and capable of supporting plants out-of-doors. Soils have horizons, roughly parallel to the earth’s surface, that indicate the degree to which materials have been altered and redistributed by water, gravity, and organisms. Individual soils occupy distinct places in the landscape, so we find patterns of soils and landscape features.
The application of photoemission, molecular orbital calculations, and molecular mechanics to the silver–poly(p‐phenylene sulfide) interface

The interfacial chemistry between evaporated Ag and poly(p‐phenylene sulfide) (PPS) has been investigated with x‐ray photoelectron spectroscopy (XPS). The initial stages of nucleation and growth of Ag in the subatomic‐layer regime were monitored. The PPS core level spectra exhibit no detectable changes as a function of Ag coverage; however, the Ag 3d5/2 peak position shifts ∼0.6 eV to higher binding energy at low Ag coverages. At low Ag coverages, the valence band spectra consist of two main features centered at 2.5 and 5.9 eV. Unrestricted Hartree–Fock (UHF) molecular orbital calculations suggest that the 5.9 eV band consists of weakly perturbed Ag 4d orbitals and bonding Ag 4d–S 3p hybrid orbitals. The 2.5 eV band consists of antibonding Ag 4d–S 3p hybrid orbitals. Molecular mechanics results suggest that the sulfur atom transforms from a bent to either a trigonal pyramidal or trigonal planar configuration after bonding with Ag. Both the molecular orbital calculations and molecular mechanics results sug.
Self‐Nucleation in the Sulfuric Acid‐Water System

Howard Reiss' ``Vector model'' was adapted to calculate the self‐nucleation rate for the sulfuric acid‐water system and similar systems.A numerical calculation was carried out for the typical case of 50% relative humidity at 25°C. It was concluded that rapid self‐nucleation would take place at sulfuric acid partial pressures in the range 10‐8‐10‐10 mm Hg. The considerable uncertainty is principally due to lack of data on the partial pressure of sulfuric acid above its aqueous solutions and on the dominant sulfuric acid‐bearing species in humid atmospheres.

Comparison of Chemical Constituents in Mung bean (Vigna radiata L.) Flour between Cultivation Regions and Seeding Dates

Legumes are one of the largest families of crop plants and are widely consumed and produced for their nutritional and commercial benefits. Mung bean (Vigna radiata L.) is a legume crop that contains various functional compounds ; moreover, it has strong antioxidant properties and is becoming an increasingly important food crop. However, most previous studies on mung beans have focused on their primary metabolites. In this study, we investigated the composition and contents of phenolic compounds, fatty acids, soyasapogenol and tocopherol in mung beans cultivated in different regions and cultivated at different seeding dates. Material analysis was conducted using the following methods: LC-MS/MS, GC-FID and HPLC-ELSD. In total, 57 different samples were analyzed. Thirteen phenolic compounds were detected in mung beans. Of these, vitexin and isovitexin were the most abundant compounds, accounting for approximately 99% of phenolic compounds. The difference in phenol compounds according to the seeding dates of mung bean was not statistically significant. The total fatty acid content in beans was the highest in Pyeongchang. Significant differences in total fatty acid content were found according to the cultivation regions. Crops grown in Sohyeon and Dahyeon showed the highest soyasapogenol B content in the Suwon region, and these were the lowest in Jeonju. The total tocopherol content of beans cultivated in Dahyeon and Sohyeon was the lowest and highest in Pyeongchang. Soyasapogenol B and total tocopherol content were not significantly different according to seeding dates. This study was conducted to obtain basic data for the cultivation of mung beans with a high content of various functional materials in terms of regional specialization and optimal seeding time.
On the importance and problems in the construction of many-body potentials

A fundamental problem exists regarding the rigorous representation of the non-additive part of the many-body potential. This is illustrated by considering the contributions to the crystal binding energies at 0 K, E(0), of the rare gases (Ne, Ar, Kr and Xe) arising from reliable two-body potentials and a variety of non-additive terms including dispersion and first-order exchange energies. The non-additive contribution to the crystal binding energies, as defined by the difference ΔE(0) between the experimental results and those evaluated from the two-body potentials, is relatively large. It is shown that while this difference corresponds (in magnitude) to the contribution arising from the non-additive dispersion energies, there can be a significant cancellation between this contribution to ΔE(0) and that arising from the non-additive first-order three-body exchange energies with a resulting disagreement with experiment. Various possible non-additive interactions are considered in an attempt to resolve this .
Critical size of transitional copper clusters for ground state structure determination: empirical and ab initio study

We studied a critical size of copper (Cu) clusters where the electronic effect and the size effect on the ground state structure become weaker. Identification of these transitional clusters thus provides with the means to efficiently determine the ground state structure of large clusters using density functional theory (DFT). Our work indicated that beyond the critical size of the transitional cluster, geometrical effects become important, and the putative global minimum structure obtained from an empirical method can be used as an initial structure to determine the true ground state structure using DFT. Structural evolution of ground states was also presented with an increase in the cluster size. To investigate low-lying structures of Cu, we used a Monte Carlo (MC)-simulated annealing method that employs the aggregate-volume-bias MC algorithm. Incorporated in the MC method is an embedded atom method potential developed by the authors. This search method identified the low-lying structures in an effective manner.
Studies on Kapok - 1. Electron Microscopic Observations

Kapok hairs were investigated by scanning and transmission electron microscopy. The fibres were also observed after mechanical and chemical treatments with the aim of studying the intemal structure of the cell walls. Three main layers of the cell wall have been found. The middle one consists of cellulosic lamellae with a gentle slope of the fibrils. The outermost layer shows a high reactivity with the staining materials but no tendency to enter into hydrogen bonds.
A Comparison of intraoperative haemodynamic profile betweendexmedetomidine and clonidine during micro-laryngoscopic surgery

BACKGROUND: Microlarygoscopic surgery is performed for treatment and staging of benign and malignant lesions of the glottis and vocal cords. Patients undergoing this procedure usually belong to the older age group. Prolonged airway manipulations during this procedure are usually associated with significant tachycardia and hypertension. Incidence of arrhythmias and perioperative myocardial ischemia is also higher. This study was done to compare the efficacy of dexmedetomidine vs clonidine premedication in providing stable intraoperative hemodynamics. We also compared the sedative effects of the two drugs. The primary outcome was intraoperative hemodynamic stability; secondary outcome was wake uptimes and sedation scores. METHODS: This was a triple blinded randomised control study and a total of 43 patients were included. They were randomised to dexmedetomidine (22 patients) and clonidine (21 patients) groups. The study drug was administered twenty minutes prior to start of surgery according to the group to which the patient was randomised. Heart rate, blood pressure and ST segment deviation were monitored during the preinduction, intraoperative and postoperative period. Sedation scores were recorded during the preinduction, at extubation and postoperative period. Data was analyses using SPSS software. RESULTS: Results from 43 patients were available for analysis. Both drugs were found to adequately reduce haemodynamic response during the procedure. There was no statistical significance between the two groups. Time to opening eyes to call was similar in both groups and there was no statistical difference between the sedation scores in either group. CONCLUSION: The use of either dexmedetomidine or clonidine as prior to induction provides adequate intraoperative stability in patients undergoing microlaryngoscopic surgery. They do not significantly affect recovery from anaesthesia.
