oordinated control of multifunctional inverters for voltage support nd harmonic compensation in a grid-connected microgrid eyyed

In this paper, a coordinated harmonic compensation and voltage support scheme is presented for distributed generations’ (DGs’) interface inverters in a resistive grid-connected microgrid. Voltage support is performed by reactive power compensation which can mitigate the over/under voltage problem; furthermore, the active power curtailment is proposed in order to mitigate the overvoltage problem when the reactive power compensation is not sufficient. Harmonic compensation is achieved by using virtual admittances in selected harmonic frequencies. Reactive power and harmonic compensation currents are istributed generation armonics compensation G interfacing inverter eactive power compensation injected with regards to the limited capacity of the interface inverter. If necessary, the reference powers of the grid-tied inverters are changed. Voltage support and harmonic compensation can be achieved based on local or central (communication-based) measurement schemes. The effect of communication delay is also investigated in this study. Experimental and simulation results are obtained in order to demonstrate the effectiveness of the proposed method. © 2017 Elsevier B.V. All rights reserved.
Hair Selenium Levels and Children ' s Classroom Behavior

The study investigated the relationship between children's hair-selenium levels and children's behavioral performance in school. Hair-selenium levels of 120 children drawn from a general school population were correlated with teachers' ratings of the children on the Walker Problem Behavior Identification Checklist (WPBIC). Parents were interviewed to control for confounding variables that may effect behavioral development. Increasing hairselenium values correlated significantly with increased scores on the WPBIC scales measuring acting out, withdrawal, and total scale score. A continuing reexamination of selenium exposure in the young is needed in order to determine the margin of safety between potentially toxic and nutritionally required levels of selenium. The importance of slight amounts of selenium in human and animal nutrition is well known (Ganther, 1974; Scott, 1981). At concentrations higher than needed for nutrition the element is toxic (Wilber, 1980), and individuals exposed to high doses of selenium are subject to CNS impairments resulting in behavioral disorders. Yang et al. (1983) described the central nervous system effects of selenium intoxication in inhabitants of a village in China. CNS abnormalities included peripheral anesthesia, acroparesthesia, 1 Associate Professor and Coordinator Area of Special Education The University of Wyoming Laramie, WY 82071 2 Laboratory Director Doctor's Data, Inc.

Variation of Alumina Sources on the Synthesis of High-Silica Mordenite from Lapindo Mud without Organic Template

Mordenite with high-silica content was successfully synthesized without organic template with variations in alumina sources. Silica was extracted from Lapindo mud using NaOH and the filtrate was titrated with HCl. The alumina sources studied in this paper includes natural zeolite, aluminum foil and sodium aluminate. The synthesis of zeolite using natural zeolite, aluminum foil and sodium aluminate was conducted under the following reaction conditions 6Na2O:Al2O3:30SiO2:780H2O at 190 o C for 24 hours; 3.5Na2O:Al2O3:20SiO2:219H2O at 165 o C for 48 hours; and 8Na2O:Al2O3: 50SiO2:960H2O at 170 o C for 24 hours respectively. The synthesized zeolite and high-silica commercial mordenite was then characterized by XRD, FTIR and XRF. The results showed that high-silica mordenite was successfully formed from sodium aluminate, while other sources formed high crystalline analcime. The results suggested the significance of the effect from impurities in the alumina sources during the synthesis of zeolites.
Relaxation Behaviour and Dipole Moment of Some Nonionics. II. CMC and Thermodynamics of Ethoxylated Alkylphenols in Nonaqueous Medium

The relaxation behaviour of octylphenol-, nonylphenoland dodecylphenol ethoxylates in benzene solutions has been studied in the frequency region 0.2 to 18 GHz at 20, 30 and 40°C. The critical micelle concentration (CMC) values of these nonionic surfactants have been located from the relaxation time-concentration and dipole moment-concentration plots through the least-squares regression analysis. The effects of the hydrophobic chain length (R) and the hydrophilic polyoxyethylene (POE) chain length on the determined CMC values, have been investigated. The thermodynamic parameters AF, AH and AS, which represent the change of free energy, activation energy and entropy have been determined at concentrations up to micelle formation. The obtained thermodynamic parameters have been discussed in terms of the molecular behaviour.
Macropinocytosis dependent entry of Chikungunya virus into human muscle cells

Chikungunya virus (CHIKV) is a re-emerging arbovirus known to cause chronic myalgia and arthralgia with high morbidity. CHIKV is now considered endemic in many countries across Asia and Africa. In this study, the susceptibility of various human, mammalian and mosquito cell lines to CHIKV infection was evaluated. CHIKV infection was found to be cell-type dependent and virus strain-specific. Furthermore, SJCRH30 (human rhabdomyosarcoma cell line) was showed to be highly permissive to CHIKV infection, with maximum production of infectious virions observed at 12 h.p.i. Pre-infection treatment of SJCRH30 with various inhibitors of endocytosis, including monodansylcadaverine (receptor-mediated endocytic inhibitor), dynasore (clathrin-mediated endocytic inhibitor), as well as filipin (caveolin-mediated endocytosis inhibitor), resulted in minimal inhibition of CHIKV infection. In contrast, dose-dependent inhibition of CHIKV infection was observed with the treatment of macropinocytosis inhibitor, 5-(N-ethyl-N-isopropyl)amiloride (EIPA). Furthermore, siRNA-mediated knockdown of sortin nexin 9 (SNX9) a protein involved in macropinosome formation, also resulted in a significant dose-dependent reduction in viral titre. By performing a virus entry assay, CHIKV particles were also observed to colocalize with FITC-dextran, a macropinosome marker. This study shows for the first time, that the infectious entry of CHIKV into human muscle cells is mediated by macropinocytosis. Together, the data from this study may pave the way for the development of specific inhibitors that target the entry process of CHIKV into cells.
Crystal growth in heater-magnet modules-from concept to use

Many concepts of external magnetic field applications in crystal growth processes have been developed to control melt convection, impurity content and growing interface shape. Especially, travelling magnetic fields (TMF) are of certain advantages. However, strong shielding effects appear when the TMF coils are placed outside the growth vessel. To achieve a solution of industrial relevance within the framework of the  project inner heater-magnet modules (HMM) for simultaneous generation of temperature and magnetic field have been developed. Global modelling was used to optimize the HMM configuration and process parameters. The successful growth of Ge and GaAs crystals in HMMequipped VGF, LEC and VCz pullers demonstrate the industrial feasibility of this project.
Acupressure to Reduce Treatment-Related Symptoms for Children With Cancer and Recipients of Hematopoietic Stem Cell Transplant: Protocol for a Randomized Controlled Trial

Background We describe the study design and protocol of a pragmatic randomized controlled trial (RCT) Acupressure for Children in Treatment for a Childhood Cancer (ACT-CC). Objective To describe the feasibility and effectiveness of an acupressure intervention to decrease treatment-related symptoms in children in treatment for cancer or recipients of a chemotherapy-based hematopoietic stem cell transplant (HSCT). Design Two-armed RCTs with enrollment of 5 to 30 study days. Setting Two pediatric teaching hospitals. Patients Eighty-five children receiving cancer treatment or a chemotherapy-based HSCT each with 1 parent or caregiver. Intervention Patients are randomized 1:1 to receive either usual care plus daily professional acupressure and caregiver delivered acupressure versus usual care alone for symptom management. Participants receive up to 20 professional treatments. Main Outcome A composite nausea/vomiting measure for the child. Secondary Outcomes Child’s nausea, vomiting, pain, fatigue, depression, anxiety, and positive affect. Parent Outcomes Depression, anxiety, posttraumatic stress symptoms, caregiver self-efficacy, and positive affect. Feasibility of delivering the semistandardized intervention will be described. Linear mixed models will be used to compare outcomes between arms in children and parents, allowing for variability in diagnosis, treatment, and age. Discussion Trial results could help childhood cancer and HSCT treatment centers decide about the regular inclusion of trained acupressure providers to support symptom management.
The Role of Perceived Legitimacy and Its Effect on Prison Adaptation: A Longitudinal Study on a Chinese Juvenile Prison

Research into offenders’ adaptation to prison environment has been a topic of enduring interest. Recently, perceived legitimacy in corrections has attracted considerable attention and emerged as an important area of research in the prison settings. The purpose of this study is to examine the factors associated with perceived legitimacy in corrections, and document its effect on juvenile offenders’ adaptation to the institutional environment of a Chinese youth prison. Data for the analysis were collected from the lone youth prison located in an autonomous region with more than 47 million persons of varying ethnicity. Using structural equation modeling (SEM), the findings suggest a significant effect for perceived legitimacy on juvenile offender adaptation to prison programs. The final model was able to explain 61% of variation in the outcome variable and identify several prominent contributors to perceived legitimacy. Policy implications were highlighted in the “Discussion and Conclusion” section.
Ultrafast Charge Carrier Relaxation in Inorganic Halide Perovskite Single Crystals Probed by Two-Dimensional Electronic Spectroscopy.

Halide perovskites are promising optoelectronic materials. Despite impressive device performances, especially in photovoltaics, the femtosecond dynamics of elementary optical excitations and their interactions are still debated. Here we combine ultrafast two-dimensional electronic spectroscopy (2DES) and semiconductor Bloch equations (SBEs) to probe the room temperature dynamics of non-equilibrium excitations in CsPbBr3 crystals. Experimentally, we distinguish between excitonic and free-carrier transitions, extracting a ~30 meV exciton binding energy, in agreement with our SBE calculations and with recent experimental studies. The 2DES dynamics indicate remarkably short, <30-fs carrier relaxation at a ~3meV/fs rate, much faster than previously anticipated for this material, but similar to that in direct band-gap semiconductors such as GaAs. Dynamical screening of excitons by free-carriers also develops on a similarly fast <30-fs timescale, emphasizing the role of carrier-carrier interactions for this material's optical properties. Our results suggest that strong electron-phonon couplings lead to ultrafast relaxation of charge carriers, which, in turn may limit halide perovskites' carrier mobilities.
Comparison of specific endophytic bacterial communities in different developmental stages of Passiflora incarnata using culture‐dependent and culture‐independent analysis

Plants and endophytic microorganisms have coevolved unique relationships over many generations. Plants show a specific physiological status in each developmental stage, which may determine the occurrence and dominance of specific endophytic populations with a predetermined ecological role. This study aimed to compare and determine the structure and composition of cultivable and uncultivable bacterial endophytic communities in vegetative and reproductive stages (RS) of Passiflora incarnata. To that end, the endophytic communities were assessed by plating and Illumina‐based 16S rRNA gene amplicon sequencing. Two hundred and four cultivable bacterial strains were successfully isolated. From the plant’s RS, the isolated strains were identified mainly as belonging to the genera Sphingomonas, Curtobacterium, and Methylobacterium, whereas Bacillus was the dominant genus isolated from the vegetative stage (VS). From a total of 133,399 sequences obtained from Illumina‐based sequencing, a subset of 25,092 was classified in operational taxonomy units (OTUs). Four hundred and sixteen OTUs were obtained from the VS and 66 from the RS. In the VS, the most abundant families were Pseudoalteromonadaceae and Alicyclobacillaceae, while in the RS, Enterobacteriaceae and Bacillaceae were the most abundant families. The exclusive abundance of specific bacterial populations for each developmental stage suggests that plants may modulate bacterial endophytic community structure in response to different physiological statuses occurring at the different plant developmental stages.
Brain-Behavior-Immune Interaction: Serum Cytokines and Growth Factors in Patients with Eating Disorders at Extremes of the Body Mass Index (BMI) Spectrum

Alterations of the immune system are known in eating disorders (EDs), however the importance of cytokine balance in this context has not been clarified. We compared cytokines and growth factors at opposite ends of BMI ranges, in 90 patients classified in relation to BMI, depressive and EDs comorbidities. Serum concentrations of interleukin (IL)-1α, IL-1β, IL-2, IL-4, IL-6, IL-8, IL-10, interferon-gamma (IFN-γ), tumor necrosis factor-alpha (TNF-α), monocyte chemoattractant protein-1 (MCP-1), vascular endothelial growth factor (VEGF), and epidermal growth factor (EGF) were determined by a biochip analyzer (Randox Labs). Differences were calculated through ANOVA. Possible predictors of higher cytokine levels were evaluated through regression analysis. IL-1α, IL-10, EGF, and IFN-γ were altered individuals with anorexia nervosa (AN) and binge eating disorder (BED). Night-eating was associated with IL-8 and EGF levels, IL-10 concentrations with post-dinner eating and negatively with sweet-eating, long fasting with higher IFN-γ levels. IL-2 increase was not linked to EDs, but to the interaction of depression and BMI. Altogether, for the first time, IL-1α, IL-10, EGF, and IFN-γ were shown to differ between AN and HCs, and between AN and individuals with obesity with or without BED. Only IL-2 was influenced by depression. Dysfunctional eating behaviors predicted abnormal concentrations of IL-10, EGF, IL-8 and IFN-γ.
Effects of Land Transport Stress on Variations in Ruminal Microbe Diversity and Immune Functions in Different Breeds of Cattle

Simple Summary Anti-stress is an emergent research point to current cattle industry. Land transport stress, a negative off-site fattening mode, causing a serious problems to beef cattle production, such as nutrition-metabolism, hormone secretion levels, and immune competence are imbalanced. In this paper we compared among Simmental Crossbred Cattle (SC), Native Yellow Cattle (NY), and Cattle Yak (CY) about ruminal microbe diversity and immune functions before and after transportation. The results showing that transport stress leads to increase secretion of hormone, both pro-inflammatory cytokines and rumen lipopolysaccharide. Meanwhile, the ruminal microbiota OTUs, Chao1, and Shannon were also changed, and Prevotella1 in NY group was higher than other groups before transport; after transport Firmicutes and Lactobacillus were increased than other groups in CY. The rumen microbiota also related with serum cytokine. Under transport stress, rumen microbiota affect the secretion of hormone levels and immune functions and breed factors affect the performance of stress resistance. Abstract The intensity and specialization of beef cattle production make off-site fattening, and introduce new breeds need transportation to achieve the goals. The present study was aimed to investigate effects of land transport stress on hormones levels, microbial fermentation, microbial composition, immunity and correlation among them among Simmental Crossbred Cattle (SC), Native Yellow Cattle (NY), and Cattle Yak (CY). High-throughput sequencing was used to investigate the rumen microbial diversity. After transport stress cortisol (COR), adrenocorticotropic hormone (ACTH) and pro-inflammatory cytokines IL-6, TNF-α, and IL-1β were increased (p < 0.05) in all groups. Rumen lipopolysaccharide (LPS) was increased (p < 0.05) in SC and CY groups. Total volatile fatty acids were increased (p < 0.05) in all groups. The ruminal microbiota about OTUs, Chao1, and Shannon in SC and CY groups were higher than before transport. Prevotella1 in NY group was higher (p < 0.05) than other groups before transport; after transport Firmicutes and Lactobacillus were increased (p < 0.05) than other groups in CY. Lactobacillus was positively correlated with IL-6 and IL-4. Under transport stress, cattle may suffer from inflammatory response through modulating HPA axis and microbiota metabolite affects the secretion of hormone levels and immune function and breeds factor affect the performance of stress resistance.

IEEE 802.11ax is the latest high rate Wi-Fi technology (also known as high efficiency Wireless) introduces some new features like OFDMA, Uplink multi-user MIMO (UL MU-MIMO) to deliver benefits in reliability, capacity, and speed. 802.11ax is better suited to some new use cases, such as live video streaming and IoT than previous versions of Wi-Fi (802.11n/ac). In this article, we study the Quality of Service (QoS) mechanism to guarantee certain levels of service to various traffic flows with the help of weighted fair queuing (WFQ) hierarchical scheduler. The multi-user mode of enhanced distributed channel access (MU mode EDCA) illustrates the controlling aspects, issues, and possible solutions of EDCA for the 802.11ax standard to satisfy QoS requirements in dense deployment scenarios.
Food store environment examination – FoodSee: a new method to study the food store environment using wearable cameras

Introduction: Food environments shape food behaviours and are implicated in rising rates of obesity worldwide. Measurement of people’s interactions with food stores is important to advance understanding of the associations between the food environment and in-store behaviour. This paper describes a new method, Food Store Environment Examination (FoodSee) to measure people’s interaction with the food store environment in a feasibility study focused on convenience stores and children. Methods: One hundred and sixty-eight randomly selected children (aged 11–13 years) recruited from 16 randomly selected schools in Wellington, New Zealand, used wearable cameras for 4 days that recorded images every 7 s. The study was conducted from July 2014 to June 2015. All images of convenience stores and service stations, and a sample of images from supermarkets, were evaluated to determine the feasibility of assessing food availability and marketing. The outcomes of interest assessed were: food product availability, placement, packaging, branding, price promotion, purchases and consumption. Results: Thirty-seven children (22%) visited a convenience store or service station at least once during the study period. In total, there were 65 visits to 34 different stores. Seven hundred and nineteen images revealed the in-store environment. Of those, 86.1% were usable and able to be analysed for the outcomes of interest. Conclusions: The FoodSee methodology provides a promising new method to study people’s interaction with the in-store food environment. The evidence generated will be valuable in understanding and improving the food store environment within which people shop, and will contribute to efforts to address obesity globally.
Ferroicity-driven nonlinear photocurrent switching in time-reversal invariant ferroic materials

Theoretical study reveals nonlinear photocurrent switching upon ferroic transition without breaking time-reversal symmetry. Nonlinear optical responses to external electromagnetic field, characterized by second- and higher-order susceptibilities, play crucial roles in nonlinear optics and optoelectronics. Here, we demonstrate the possibility to achieve ferroicity-driven nonlinear photocurrent switching in time-reversal invariant multiferroics. It is enabled by the second-order current response to electromagnetic field whose direction can be controlled by both internal ferroic orders and external light polarization. Second-order direct photocurrent consists of shift current and circular photocurrent under linearly and circularly polarized light irradiation, respectively. We elucidate the microscopic mechanism in a representative class of two-dimensional multiferroic materials using group theoretical analyses and first-principles theory. The complex interplay of symmetries, shift vector, and Berry curvature governs the fundamental properties and switching behavior of shift current and circular photocurrent. Ferroicity-driven nonlinear photocurrent switching will open avenues for realizing nonlinear optoelectronics, nonlinear multiferroics, etc., using the coupled ferroic orders and nonlinear responses of ferroic materials under external field.
