Published: March 2021

Abstract
Background: A subset of adolescents with mental disorders are likely to be (share) decision making competent and hence can make their treatment engagement more effective. Treatment engagement is decisive in achieving successful outcomes. However, there are high rates of drop-out in mental health settings.Aim: This study aims at identifying barriers to or facilitators of mental health care engagement among adolescents with decision-making competence in Greece. Methods: Participants were adolescents in therapy for mental disorders recruited from an outpatient tertiary hospital setting. First, potential participants with decision making competence were identified. Second, 50 participants were interviewed about their perceptions of treatment. The interviews were auto-recorded. A transcription verbatim and data analysis were conducted. All the requirements of a qualitative research and ethical considerations were observed.Results: All the participants highlighted their experience with facilitators rather than barriers to their treatment engagement. Facilitators included: a) positive treatment outcomes and adolescent's perceived usefulness of treatment, b) a meaningful adolescent-therapist relationship, c) family’s supportive role, d) symptoms and negative self-image, and e) developing social relationships and acceptance by peers. The participants equally highlighted the importance of getting rid of their symptoms and improve their socialization skills. Other facilitators included: achieving professional and personal goals in life, enhancing their independence and self-esteem / self-image, or even just confessing to another trustworthy person. Friends were reported as having a neutral or mild supportive role. The barriers included ineffective and unhelpful treatment, negative experiences with their therapist, relief from symptoms and mental health therapy-related stigma. Conclusion: For the most part, the findings enhance prior studies. Participants highlighted facilitators rather than barriers to treatment engagement. For the most part, the findings enhance prior studies. However, we identified some nuances which might be used by therapists to enhance the adolescents’ treatment engagement. For instance, bearing in their mind that by the subsiding of symptoms adolescents are most likely to terminate the treatment prematurely and highlighting the achievement of adolescents’ future goals as well as the potential family’s enhanced well-being because of the improvement of adolescents’ mental health may contribute to reducing the attrition rate.

Abstract
The paper presents result of CFD simulations of a series of centrifugal compressor stage vane diffusers in the Ansys CFX. Objects of research are vane diffusers with external relative diameter (relative to the diameter of the impeller) equal to 1.5, vane inlet angle of 20 degrees, relative vane heights of 0.025, 0.034, 0.045, 0.06, 0.08, vane profile curvature angles of 10, 15, 20 degrees. The characteristics of polytrophic efficiency, loss coefficient, recovery coefficient, ratio of inlet and outlet velocities, flow deviation angle versus incidence angle are set. The analysis of the flow structure in the vane diffuser channels is presented. Unlike with a straight vane cascade, the deviation angle in the circular rows of vane diffusers tends to increase with increasing row density. This may be due to the complex nature of the interaction of the active part of the flow with separation zones. In rows with almost straight vanes at a lower density, the separation zone on the pressure side decreases, and even shifts to the very end of the suction side.

Abstract
Multi user - Multiple-input multiple-output (MU-MIMO) based wireless communication system has several advantage over conventional MIMO systems such as high data rate and channel capacity which drawn great attention recently and prominently preferred for 5G systems. And on the other side interferences due to the multi user mobile environment such as co-channel interference and multiple access interference the overall system performance will be degraded and highly reliable techniques need to be incorporate to improve the Quality of services. Moreover the energy efficiency and compactness requirement of 5G systems presents new challenges to investigate techniques for reliable communications. In this paper we introduce a novel low-complexity radix factorization based fast Fourier transform multi beam former and maximal likelihood –multi user detection (ML-MUD) techniques as signal detector tailored with optimal sub detector systems which results with considerable complexity reduction with intolerable error rate performance. The proposed radix factorized Fast Fourier transform - multi-beam forming (RF-FFT-MBF) architectures have the potential to reduce both hardware complexity and energy consumptions as compared to its state-of-the-art methods while meeting the throughput requirements of emerging 5G devices. Here through simulation results the efficiency of scaled ML sub detector system at the downlink side is compared with the conventional ML detectors. Through experimental results it is well proved that the proposed detector offers significant hardware and energy efficiency with least possible error rate performance overhead.

Abstract
Background: Hand hygiene is one of the simplest and most important ways to prevent nosocomial infections. However, the available evidence indicates that hand hygiene is not fully practiced by healthcare workers. Several factors affect hand hygiene. Therefore, this study aimed to explain the experiences of healthcare workers in the barriers to hand hygiene compliance in intensive care units.Methods: This qualitative study was performed on 25 doctors, anesthesiologists, nurses and physiotherapists working in intensive care units by using purposive sampling and semi-structured individual interviews. The data analysis process was performed with Lundman and Graneheim approach.Results: The main theme of “barriers to hand hygiene practice” with three main categories, including 1- barriers related to healthcare providers with subcategories of workload, insufficient knowledge, inappropriate attitude and wrong behavioral patterns, 2- barriers related to management with the subcategories of improper planning and training, improper design of the physical space of the department and 3- barriers related to equipment and facilities with the subcategories of lack of equipment and poor quality equipment were identified in this study.Conclusion: The results of the present study can help the relevant authorities in adopting appropriate strategies to remove barriers to hand hygiene practice and promote the right attitude and behavior in healthcare workers.
Phase Transformation of Cr(VI)-Adsorbed Ferrihydrite at Different pH in The Presence of Mn(II): Fate of Mn(II) and Cr(VI)

Published: March 2021

Abstract
Ferrihydrite is an important sink for the toxic heavy metal ions, such as chromium(VI). As ferrihydrite is thermodynamically unstable and gradually transforms into hematite and goethite, the stability of Cr(VI)-adsorbed ferrihydrite is environmentally significant. This study investigated the phase transformation of Cr(VI)-adsorbed ferrihydrite at different pH in the presence of aqueous Mn(II), as well as the fate of Mn(II) and Cr(VI) in the transformation process of ferrihydrite. Among the ferrihydrite transformation products, hematite was dominant, and goethite was minor. The pre-adsorbed Cr(VI) inhibited the conversion of ferrihydrite to goethite at initial pH 3.0, whereas little amount of adsorbed Mn(II) favored the formation of goethite at initial pH 7.0. After the aging process, Cr species in solid phase existed primarily as Cr(III) in the presence of Mn(II) at initial pH 7.0 and 11.0. The aqueous Mn concentration was predominantly unchanged at initial pH 3.0, whereas the aqueous Mn(II) was adsorbed onto ferrihydrite or form Mn(OH)2 precipitates at initial pH 7.0 and 11.0, promoting the immobilization of Cr(VI). Moreover, the oxidation of Mn(II) occurred at initial pH 7.0 and 11.0, forming Mn(III/IV) (hydr)oxides.

Abstract

Purpose: In the United States, there are almost 17 million cancer survivors who often have poorer health outcomes and an increased risk for developing a second cancer and other chronic illnesses. Evidence suggests substantial cancer burden may be prevented through lifestyle modifications. The purpose of this study was to determine the feasibility of health coaching for the improvement of health, fitness, and overall well-being of cancer survivors in a community setting. Methods: Participants were recruited from community-based cancer agency locations. Health coaching was provided to people diagnosed with cancer anywhere along the cancer survivorship continuum. Coaches provided six individual sessions to each participant. Surveys were sent pre- and post-intervention on topics including fitness, eating habits, perceived stress, anxiety, depression, and quality of life. Results were analyzed using repeated measures multilevel modeling. Results: 48 participants completed an average of 85% of health coaching sessions. Coaching participants noted significant improvements in weekly physical activity, including moderate-vigorous physical activity. Small significant increases were found in healthy eating behavior. Participants reported moderate change in the quality of their sleep and smaller significant changes in sleep duration and sleep efficiency. Moderate significant reductions were found in perceived stress and anxiety, with small but significant decreases in depression. Importantly, participants reported improved quality of life, particularly in areas of physical and emotional well-being. Smaller increases were found in functional and total well-being. Conclusion: Preliminary findings indicate real behavior change in the measured outcomes and suggests health coaching may be an important tool for cancer survivorship.
Distribution of Arsenic in Fresh and Weathered Rocks in Sri Lanka
Authors: Jayawardena U.de S. 
Published: March 2021

Abstract
This study was carried out to determine the distribution of arsenic, which may slowly harm human health, in the weathered rocks of different parent rocks in the country. 293 samples were collected from different crystalline rocks and in-situ weathered formations above the particular parent rock in 50 localities. Selected minor elements (including arsenic) were analysed by X-ray fluorescence spectrometry on RIGAKU KG-X system (Japan). Results indicated that the maximum arsenic amount in the fresh rock was 12 and 48 ppm in completely weathered rocks. About 86.9% of fresh rocks showed less than 5 ppm of arsenic, while 89.8% of their weathered grades showed the arsenic concentration to be less than 10 ppm. Average arsenic in all fresh rock samples was 3.5ppm (lowest); it was 7.6 ppm (highest) in residual soils. This is the normal condition of arsenic distribution worldwide. Under this condition, the arsenic concentration in natural groundwater in the residual soil areas should be below the acceptable limit. Therefore, the amount of arsenic released from parent rocks and their weathered products due to natural geological processes is very low in Sri Lanka.

Abstract
Background: The aim of this study is to identify the genetic defect in a Chinese family with congenital aniridia combined with cataract and nystagmus.Methods: Complete ophthalmic examinations, including slit-lamp biomicroscopy, dilatedindirect ophthalmoscopy, anterior segment photography, and anterior segment optical coherence tomography (OCT) were performed. Blood samples were collected from all family members and genomic DNA was extracted. Genome sequencing was performed in all family members and Sanger sequencing was used to verify variant breakpoints.Results: All the thirteen members in this Chinese family, including seven patients and six normal people, were recruited in this study. The ophthalmic examination of affected patients in this family was consistent with congenital aniridia combined with cataract and nystagmus. A novel heterozygous deletion (NC_000011.10:g.31802307_31806556del) containing the 5’ region of PAX6 gene was detected that segregated with the disease. Conclusion: We detected a novel deletion in PAX6 responsible for congenital aniridia in the affected individuals of this Chinese family. The novel 4.25kb deletion in PAX6 gene of our study would further broaden the genetic defects of PAX6 associated with congenital aniridia.

Published: March 2021

Abstract
Animal models are often used to assess the airborne transmissibility of various pathogens, which are typically assumed to be carried by expiratory droplets emitted directly from the respiratory tract of the infected animal. We recently established that influenza virus is also transmissible via “aerosolized fomites,” micron-scale dust particulates released from virus-contaminated surfaces (Asadi et al., Nature Communications, 2020). Here we expand on this observation, by counting and characterizing the particles emitted from guinea pig cages using an Aerodynamic Particle Sizer (APS) and an Interferometric Mie Imaging (IMI) system. Of over 9,000 airborne particles emitted from guinea pig cages and directly imaged with IMI, none had an interference pattern indicative of a liquid droplet. Separate measurements of the particle count using the APS indicate that particle concentrations spike upwards immediately following animal motion, then decay exponentially with a time constant commensurate with the air exchange rate in the cage. Taken together, the results presented here raise the possibility that a non-negligible fraction of airborne influenza transmission events between guinea pigs occurs via aerosolized fomites rather than respiratory droplets, though the relative frequencies of these two routes have yet to be definitively determined.

Published: March 2021

Abstract
Background

Hypoxia is a prominent feature of solid cancer. This research aims to expose the role of mitochondrial creatine kinase 1 (CKMT1) in non-small cell lung cancer (NSCLC) progression and hypoxia adaptation.
Methods

The mRNA and protein expression of CKMT1 in NSCLC tissues and cells were detected using GEPIA web, immunohistochemistry, qRT-PCR and western blot. Cells were exposed to a hypoxic chamber with atmosphere containing 5% CO2, 1% O2 and residual N2. The protein levels of HIF-1α and CKMT1 in H1650 and H1299 cells exposed to hypoxia were determined by western blot. Luciferase activity assay and HIF1 specific inhibitor (LW6) assay indicated the related function of HIF-1 and CKMT1. The role of CKMT1 to NSCLC cells biological function on hypoxic condition was measured by CCK8, colony formation, transwell and apoptosis assay.
Results

CKMT1 was highly expressed in NSCLC tissues and cells using GEPIA web, immunohistochemistry, qRT-PCR and western blot. Hypoxia induced the accumulation of HIF-1α and the expression of CKMT1 in H1650 and H1299 cells. The results of luciferase activity assay and HIF1 specific inhibitor (LW6) assay indicated that HIF-1, as a transcription factor of CKMT1, up-regulated the expression of CKMT1 under hypoxic conditions. Further, knockdown of CKMT1 inhibited the cell proliferation and invasion of H1650 and H1299 cells, which could be rescued by hypoxia.
Conclusions

In summary, CKMT1 has the potential as a target for NSCLC hypoxic targeted therapy.
An Energy-Equivalent Simplified Model for Lateral Nonlinear Vibrations of Coupled Water Turbine Generator Set Shaft-Foundation System
Authors: Sun Wanquan , Guo Zhiqiang , Ma Zhenyue 
Published: March 2021

Abstract
The traditional whole finite element method (WFEM[1]) has several shortcomings, including that it has too many degrees of freedom so the execution is not efficient and is difficult to solve in nonlinear dynamic analysis. In this paper, a novel simplified modeling approach is proposed to investigate the lateral nonlinear vibration characteristics of coupled water turbine generator set shaft-foundation system (CSFS[2]). The simplified coupled model is generated in two stages. First, a more reasonable simplified model for foundation subsystem considering coupling with each other is constructed to simulate the lateral vibrations of guide bearing foundations in hydropower house. Based on the response spectra of WFEM of hydropower house and a constructed energy error objective function, the optimal equivalent parameters of the simplified foundation model are then determined by using the genetic algorithm. Second, considering actions of various nonlinear factors and the pulsating water pressure acting on turbine runner, a nonlinear dynamic differential equations of CSFS based on Lagrange equation are derived. The nonlinear dynamic responses of CSFS using the optimal equivalent model are also compared with the field test data. It is demonstrated that the method proposed to develop the equivalent model is more efficient and more convenient in capturing the nonlinear dynamic behavior of CSFS. In addition, this energy-equivalent model is more adaptable to the stochastic uncertainty and frequency band variation in hydropower station system. Some novel dynamic laws and inner mechanism of the coupled system are also revealed further based on the proposed model.

Published: March 2021

Abstract
Background

Given the wide range of depressive disorders, suicidal ideation and suicide attempts in various military studies around the world, determining the exact prevalence of these disorders in line with health planning as well as care and treatment service designing for military forces can be useful. The aim of the present meta-analysis was to determine the pooled prevalence of depressive disorders, suicide thoughts, and attempts in the military.
Methods

The present systematic review and meta-analysis study was performed based on PRISMA criteria in 5 steps of the search strategy, screening and selection of articles, data extraction, evaluation of article quality and meta-analysis. International databases (PubMed, Scopus, Web of Sciences, Embase, Cochrane, PsycInfo) were searched using related keywords extracted from Mesh and Emtree. After screening and final selection of articles, data were extracted and qualitative evaluation was performed using the NOS checklist.
Results

The results of meta-analysis showed that the prevalence of depression in active military forces and veterans was 23% (%95 CI: 20–26 %) and 20% (%95 CI: 18–22 %), respectively. In addition, the prevalence of suicidal ideation and attempts in the military was 11% (%95 CI: 10–13 %) and 11% (%95 CI: 9–13 %), respectively. The prevalence of suicide ideation and attempts in drug-using military was 18% (%95 CI: 7–33 %) and 30% (%95 CI: 23–36 %), respectively. The prevalence of suicidal ideation and attempts in military consuming alcohol were 9% (%95 CI: 4–13 %) and 8% (%95 CI: 7–10 %), respectively. In militaries with AIDS / HIV, the prevalence of suicide attempts was 5% (%95 CI: 4–8 %).
Conclusion

Therefore, it is necessary to develop and design training and intervention programs in order to increase the awareness of the military, especially veterans, to prevent the occurrence of suicide and depression.

Published: March 2021

Abstract
Background: Colostrum is the first food for mammals that should give a head start to the newborn organism. By providing the body with essential nutrients, colostrum plays an immune and immunostimulating function. Colostrum quality depends on multiple factors, including microbial effect. Widespread coagulase-negative staphylococci have a great impact on colostrum qualitative indicators. The aim of this study was to explore the effect of staphylococci on colostrum quality. Results: Physical, chemical properties and fatty acid profile of cow’s colostrum were determined. In our study we identified three pathogenic coagulase-negative Staphylococcus species in the cows’ colostrum: S. sciuri (64.29 %), S. xylosus (28.57 %) and S. warneri (7.14 %). We noted that the somatic cell count (SCC) in the affected colostrum samples wasn’t noticeably higher than that in the uninfected colostrum samples. Percentage of dry matter in infected and uninfected colostrum samples was nearly the same. Contents of fat, protein, and lactose in the studied colostrum were not significantly different. The content of butyric (С4:0) and capric (С10:0) acids was significantly higher (P<0.05) in the colostrum fat of cows infected with CNS compared to that of the uninfected animals. Conclusions: According to our research infection with coagulase-negative staphylococci negatively affects colostrum patameters primarily due to an increase in SCC, acidity and decrease in β-casein level. Moreover, significant decrease in total bacterial count in infected by CNS samples may be caused by a decrease in the level of beneficial microflora. Minor changes in fatty acid profile of fat in colostrum with CNS do not have a significant negative effect on colostrum as a whole. But in view of the fact that colostrum is intended for feeding a newborn with a "sterile" gastrointestinal tract, the presence of CNS will undoubtedly leads to a great threat to an immature organism.
