DESENVOLVIMENTO, COMPOSIÇÃO CENTESIMAL E ANÁLISE SENSORIAL DE BARRAS À BASE DE GRÃOS DE QUINOA (CHENOPODIUM QUINOA WILLD.) SUBMETIDOS A DIFERENTES TRATAMENTOS TÉRMICOS

Objective: Considering the high nutritional value of quinoa grain, with protein composed by all essential amino acids, this study aimed to develop cereal bars elaborated with this grain after two different thermal processing, to evaluate the chemical composition and to verify the preference between the bars using a sensory analysis. Material and methods: The bars were prepared with quinoa submitted to hydration process in water and toasting process. It was performed the chemical composition (moisture, ash, crude fiber, protein, lipids and carbohydrates) of the grains and quinoa bars. The sensory analysis for verification of preference between the bars was performed by hedonic scale of 7 points and purchase intent by 5-point scale. Results: The lipid, crude fiber, ash and carbohydrate contents of quinoa grains had variations after thermal processing. Between the bars, there were significant differences in protein, ash and carbohydrates amount. In the sensorial analysis, the bar containing toasted quinoa grains was preferred, with good acceptability index (85%), while the bar containing hydrated quinoa grains presented a lower rate (66.34%), not being accepted, mainly because of its softened texture. The same occurred in purchase intent, which consumers showed that would probably buy the bar elaborate with toasted grains and would maybe buy the bar containing hydrated grains. Conclusion: The cereal bar produced with toasted quinoa grains is the best formulation for product development, which has viability to be commercialized, as it obtained a good acceptability index.

Electrochemical activities of syntrophic acetate oxidizing bacteria and redox mediators: Usability of methyl viologen and neutral red as electron transmitters.

The anaerobic digestion process, which uses microorganisms to produce biogas, is common in the treatment of sludge at wastewater treatment plants. Syntrophic acetate oxidizing bacteria (SAOB) play an important role in anaerobic digestion under certain environmental conditions, such as high ammonium concentration. The SAOB oxidize acetate and produce hydrogen, which is consumed by co-existing hydrogenotrophic methanogens. Studying SAOB in isolation is difficult since they are dependent on the methanogenic partner to keep the hydrogen concentration low, which is necessary for anaerobic acetate oxidation to be thermodynamically possible. Electrochemical systems could potentially help in growing SAOB isolated. If the SAOB could direct electrons to the anode instead of hydrogen, growth on acetate could theoretically be possible without a methanogenic partner. In this study, growth of SAOB in electrochemical reactors in the presence of different redox mediators was investigated. The aim was to find a mediator able to serve as electron shuttle from the bacteria to the electrode of an electrochemical system. Neutral red showed through cyclic voltammetry to be the most promising. Hence SAOB were grown at a constant potential with the possible mediator neutral red. Throughout the experiment the activity of the SAOB was observed through liquid and gas samples. The activity of the bacteria was high during the experiment and cyclic voltammetry indicated some usage of neutral red. However, only very few electrons were transferred to the electrode. Hence the bacteria cannot use neutral red as mediator to grow at a constant potential. Additionally, the mediator methyl viologen was shown to inhibit growth. Still, there a several more mediators to investigate on the possible use as mediators for SAOB. The formal potentials of humic acid, cysteine, AQDS, resazurin and methylene blue were determined in this thesis.
Direct Insight into Ethane Oxidative Dehydrogenation over Boron Nitrides

The ultimate objective of chemical conversion is to achieve 100 % selectivity from catalysis, and this is also a prodigious challenge for the conversion of light paraffins into olefins, because it involves controlled activation of highly stable aliphatic C−H bonds. Herein, we show that metal‐free boron nitride (BN) nanosheets not only enable the oxidative dehydrogenation of ethane to ethylene exclusively at near 10 % conversion, but they also deliver a remarkable 60 % selectivity at an ethane conversion of 78 % and remain stable over 400 h at 575 °C. Our operando infrared spectroscopy and 18O isotope tracer study explicitly demonstrates that B−O(H) active sites are formed at the edges of BN through the aid of ethane, and the dehydrogenation circle is completed over these B−O sites by the assistance of O2.
Investigation on the Mental Health of Healthcare Workers for Aid in Hu Bei Province During the Outbreak of Covid-19 Based on the Network Survey

Background:The objective of this study isto explore the mental health of healthcare workers went to Hubei for assistance during the outbreak of COVID-19.A total of 210 medical staff who traveled to Hubei Province for assistance in the first time completed the online questionnaire, including the Sleep Self-Assessment Scale (SRSS), Generalized Anxiety Scale (GAD-7), and 9-item patient health questionnaire (PHQ-9). Results:The average score of the SRSS of all the subjects（25.13±6.41）was significantly higher than the national norm（22.14±5.48）(p <0.001). The average score of the GAD-7 of all subjects（12.37±4.89）was at the level of moderate anxiety, while the average score of the PHQ-9 of them （8.90±5.42）was at the level of mild depression. The scores of SRSS and GAD-7 of all males（26.60±6.38, 14.45±3.80）were significantly higher than those of females（23.67±6.12, 10.28±4.99）(p <0.01). Conclusions: In this epidemic, the sleep quality of frontline medical staff in Hubei Province is poor, and the symptoms of anxiety and depression are common, while the anxiety is more prominent. Among them, the sleep and anxiety symptoms of males are more obvious than that of women, suggesting that we should pay attention to the psychological support of male doctors and nurses and provide them with appropriate psychological decompression training.
Fe3O4@SiO2-SnCl4: An Efficient Catalyst for the Synthesis of Xanthene Derivatives under Ultrasonic Irradiation

ABSTRACT Grafting of SnCl4 on the Fe3O4@SiO2 nanoparticles afforded Fe3O4@SiO2-SnCl4 as a novel inorganic heterogenous catalyst, which was characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), vibrating sample magnetometry (VSM), Field Emission Scanning Electron Microscopy (FE-SEM), and transmission electron microscopy (TEM). In this research, we report a convenient and efficient direct protocol for the preparation of xanthene derivatives via condensation of β-naphthol, dimedone, or mixture of β-naphthol and dimedone with various aromatic aldehydes in the presence of the catalytic amount of Fe3O4@SiO2-SnCl4 under ultrasonic irradiation. This procedure has a lot of advantages such as: very easy reaction conditions, absence of any tedious workup, or purification, and much milder method. The corresponding products have been obtained in excellent yields, high purity, and short reaction times.
Vitamin D3 Level And Risk of Diabetes In Patients With Hyperuricemia

BackgroundPrevious studies have shown that hyperuricemia is involved in diabetes, obesity, hypertension, chronic kidney disease, and other diseases. At the same time, studies have shown that vitamin D3 levels in the body are linked to the onset of diabete. However, there is currently no sufficient evidence to prove whether this connection is affected by uric acid levels. Therefore, we attempted to investigate the relationship between vitamin D3 content and the occurrence of diabetes in the hyperuricemia population by using the data of the NHANES database from 2009 to 2018.MethodWe conducted a cross-sectional study using the NHANES database. According to strict inclusion and exclusion criteria, we finally selected 3543 representative data. Multivariate logistic regression analysis was used to explore the relationship between vitamin D3 and diabetes in the hyperuricemia population after complete adjustment. We found a linear relationship between vitamin D3 content and the incidence of diabetes.ResultThe results of this study showed that there was a correlation between the content of vitamin D3 and the incidence of diabetes in people with hyperuricemia, and the effect values (OR and 95% confidence interval) were 0.95and (0.92-0.98), respectively, and the difference was statistically significant.ConclusionOur study shows that vitamin D3 content is associated with the incidence of diabetes in people with high uric acid. This study provides a new idea for exploring the factors affecting the pathogenesis of diabetes in patients with hyperuricemia.
Immigration of Sogatella Furcifera from the Greater Mekong Subregion into Northern China Revealed by 2b-RAD Sequencing

Background The white-backed planthopper (WBPH), Sogatella furcifera (Horváth) (Hemiptera, Delphacidae), is a migratory pest of rice in Asia. Shandong Province, in northern China, is located on the migration pathway of WBPH between southern and northeast China. The potential sources of WBPH in northern China are poorly understood. We studied the sources of WBPH in Shandong Province by determining the population genetic structure of WBPH in 18 sites distributed in Shandong and in six regions of the Greater Mekong Subregion (GMS). We used mitochondrial gene and single-nucleotide polymorphism (SNP) markers (2b-RAD sequencing) for analysis.Results All of the WBPH populations studied in the seven regions had low genetic diversity. Pairwise FST values ranged from − 0.061 to 0.285, while FST based on SNP data ranged from − 0.007 to 0.009. These two molecular markers revealed that 4.40% (mtDNA) and 0.19% (SNP) genetic variation could be explained by the interpopulation variation, while the rest came from intrapopulation variation. The populations in the seven geographic regions comprised four hypothetical genetic clusters (K = 4) not associated with geographic location. Eighty-four of 129 individuals distributed across the given area were designated as recent migrants or of admixed ancestry. Although the substantial migration presented, a weak but significant correlation between genetic and geographic distances was found (r = 0.083, P = 0.004). Conclusion GMS was the main source of WBPH in Shandong, while other source populations may also exist. The genetic structure of WBPH is shaped by both migration and geographic barriers. These results help clarify the migration route and the source of WBPH in northern China.
Synthesis, crystal structure and fluorescent properties of two metal-organic frameworks constructed from Cd(II) and 2,6-naphthalene dicarboxylic acid

ABSTRACT Aimed at exploring the effect of reaction conditions on the formation of crystal structures of metal-organic framework materials (MOFs), two new MOFs [Cd3(2,6-NDC)3(DMF)4(NO3)] (1) and [Cd2(2,6-NDC)2(DMF)2] (2), have been prepared using Cd(II) and 2,6-naphthalene dicarboxylic acid (2,6-NDC) at variable temperature and different solvents. 3-D framework structures of 1 and 2 are formed through interconnection of fully deprotonated 2,6-NDC with trinuclear cluster of secondary building units. Further, both MOFs emitted blue fluorescence with diverse intensities in solid state at room temperature.
The Optimization of The Synthesis and Characterization of Vapor-Liquid-Solid Grown ZnO Nanowires

OF THESIS THE OPTIMIZATION OF THE SYNTHESIS AND THE CHARACTERIZATION OF VAPOR-LIQUID-SOLID GROWN ZnO NANOWIRES ZnO nanowires are a promising material with great semiconductor properties. ZnO nanowires were prepared by carbothermal reduction and vapor-liquid-solid growth mechanism. Altering a variety of parameters ranging from mole to mole ratio of ZnO to C all the way to gas flow rate was examined. The nanowires were then characterized and their morphology examined under a SEM to observe what effect the parameter had on the morphology of the nanowires. From the experiments and the parameters tested it was observed that in order to produce the highest quality straight nanowires one should use a mole to mole ratio of ZnO to C graphite of 1 to 3. With a dwell temperature and time of 900 °C for 3 hours. A gold seed catalyst of 4nm and a gas flow rate of 50 to 100sccm of Ar provides the straightest nanowires. Understanding the effect of each parameter on the morphology of ZnO nanowires is vital for the current research. This will only lead to further the research and provide a better understanding of the growth mechanism of these wires and how the production of specific wires with certain morphologic features and characteristics can be achieved.
Üniversite Öğrencilerinin Umutsuzluk, Kaygı ve İlişkilerle İlgili Bilişsel Çarpıtmaları

Interpersonal Cognitive Distortions, The Level of Anxiety and Hopelessness of University Students Objective: The purpose of this study is to determine university students’ interpersonal cognitive distortions, the level of anxiety and hopelessness and to find out the differences of gender and age in terms of students’ interpersonal cognitive distortions, the level of anxiety and hopelessness. Method: To this study 287 (%78.6) female, 78 (%21.4) male, total 365 university students participated. Hopelessness Scale, anxiety Inventory, and interpersonal cognitive distortions Scale were used to collect data and the data was analyzed by using SPSS. Descriptive statistics (mean and standard deviation) and One Way ANOVA was used to analyze the data. Results: The results of the analyses showed that male and female university students who are age of 21-25 years old are relatively higher than other age groups in their interpersonal cognitive distortions, the level of anxiety, and hopelessness. There were no significant differences between male and female students in terms of interpersonal cognitive distortions, the level of anxiety and hopelessness. In other words, male and female university student’s interpersonal cognitive distortions, the level of anxiety and hopelessness were not significantly different and both male and female students who are age of 21-25 years old have relatively higher means in terms of interpersonal cognitive distortions, the level of anxiety and hopelessness. Conclusion: The results were not consistent with the literature. The reason of this could be that this study was made on healthy populations that are not diagnostic patients and this study was made on the students who continue to the foundation university.

On the move: Exploring health service providers’ perspectives about family participation in care in Nunavik, a qualitative study.

BackgroundLiterature on participation in health and social services suggests that youth are difficult to engage within health and social services. Indigenous youth are less likely to access services or to actively participate in decision-making regarding their personal care. This article analyzes health and social service providers’ perspectives, experiences and expectations regarding the roles of a particular group of Indigenous youth, families and community in care settings in Nunavik, Quebec.MethodsA snowball sampling method was used to recruit participants. A total of 58 participants were interviewed including psychiatrists, general practitioners, nurses, social workers, school principals, teachers, student counsellors, representatives of local committees (education committee, health committee), and police officers. Of the 58 participants, 39 were non-Inuit and 19 were Inuit. The interviews focused on three broad themes: 1) participants’ current and past positions/roles; 2) participants’ perceptions of the clientele (youth and their families) they work with; and 3) participants’ understanding of collaborations taking place within and between services (who works with whom) and community. Applied thematic analyses were conducted. The model that we present allows us to describe health service provider expectations and experiences regarding patient and community participation. ResultsWe organize findings around three themes: I) The most commonly described interventions, II) different types of challenges to and within participation; and III) what successful participation can look like according to service providers. Participants speak of the challenges for families to go towards services as well as the challenges for services providers to go towards youth and families, including personal, organisational and historical factors. Conclusion﻿We adopt a critical lens to reflect on the key findings in order to tease out points of tension and paradoxes that might hinder the participation of youth and families. We then use a constructive lens to amalgamate and build on service providers’ descriptions of challenges and successes to identify promising approaches that seem to encourage participation of youth and families.
Kinetics of sorption and desorption of copper(II) and lead(II) on activated carbon

The rate of sorption of copper(II) and lead(II) onto activated carbons Nuchar SA and Filtrasorb 400 was observed to occur rapidly at the outset, followed by a slow and prolonged sorption. This indicates that previous sorption studies conducted for short equilibration periods likely underestimated the actual capacity of activated carbon for heavy metals. Although copper and lead ions desorbed from the activated carbon surface rapidly, the rate of desorption of lead was slower, prevailing over several days. Sorption of copper and lead ions on Nuchar SA was found to be fully reversible
Recent Advances in Transition-Metal-Catalyzed Synthesis of Coumarins

Abstract Coumarin is a privileged scaffold found in a large number of biologically active natural products, pharmaceuticals and agrochemicals, and functionalized coumarins are also widely employed as materials. For this reason, considerable interest has been focused on the development of new protocols to access this heterocyclic moiety in the past few decades. Among the numerous methods developed so far, transition-metal-catalyzed reactions are the most attractive methodologies for the synthesis of coumarins under rather mild reaction conditions. This review provides an overview of the recent developments in this field. 1 Introduction 2 Palladium Catalysis 3 Platinum Catalysis 4 Cobalt Catalysis 5 Copper Catalysis 6 Gold Catalysis 7 Iron Catalysis 8 Nickel Catalysis 9 Rhodium Catalysis 10 Ruthenium Catalysis 11 Zinc Catalysis 12 Conclusion
Bioinformatics and Expression Analysis of Histone Modification Genes in Grapevine Predict Their Involvement in Seed Development and Hormonal Signaling

Background Histone modification genes (HMs) play potential roles in plant growth and development via influencing gene expression and chromatin structure. However, limited information is available about HMs genes in grapes (Vitis vinifera L.). Results Here, we described detailed genome-wide identification of HMs gene families in grapevine. We identified 117 HMs genes in grapevine and classified these genes into 11 subfamilies based on conserved domains and phylogenetic relationships with Arabidopsis. We described the genes in terms of their chromosomal locations and exon-intron distribution. Further, we investigated the evolutionary history, gene ontology (GO) analysis, and syntenic relationships between grapes and Arabidopsis. According to results 21% HMs genes are the result of duplication (tandem and segmental) events and all the duplicated genes have negative mode of selection. GO analysis predicted the presence of HMs proteins in cytoplasm, nucleus, and intracellular organelles. According to seed development expression profiling, many HMs grapevine genes were differentially expressed in seeded and seedless cultivars, suggesting their roles in seed development. Moreover, we checked the response of HMs genes against powdery mildew infection at different time points. Results have suggested the involvement of some genes in disease resistance regulation mechanism. Furthermore, the expression profiles of HMs genes were analyzed in response to different plant hormones (Abscisic acid, Jasmonic acid, Salicylic acid, and Ethylene) at different time points. All of the genes showed differential expression against one or more hormones. Conclusion VvHMs genes might have potential roles in grapevine including seed development, disease resistance, and hormonal signaling pathways. Our study provides first detailed genome-wide identification and expression profiling of HMs genes in grapevine.
Unilateral Biportal Endoscopic Lumbar Interbody Fusion. Technical Note and Surgical Comparison with Conventional MIS TLIF.

Backgrounds : Minimally invasive surgery develops very extensively in past few decades, not only in the scope of decompression but until fusion surgery. Surgeon has been trying to reduce the damage to the normal anatomical structure. In this study we performed unilateral biportal endoscopic lumbar interbody fusion (ULIF) as one of the fusion option which is readily available without sophisticated minimal invasive instrument. The purpose of this study is to introduce unilateral biportal endoscopic surgery and comparing the result with conventional minimal invasive lumbar interbody fusion (MIS-TLIF) Methods : This is a retrospective cohort study of 145 lumbar spondylolisthesis patient underwent conventional MIS-TLIF or ULIF procedure. All patient were followed up until 12 months to evaluate the VAS of back pain and leg pain, ODI, SF-36 and fusion rate. Results : Back pain VAS were a little higher compared with the endoscopic group, but the VAS of leg pain were the same. Both group had improvement in ODI score and SF-36 which shows both of the procedure were quite effective in managing such cases. Conclusion : Full endoscopic fusion offer benefit of minimal invasive surgery with better visualization of decompression and endplate preparation. Long term follow up is still needed to evaluate the result of the procedure.
Effective Extraction of Vanadium and Chromium from High Chromium Content Vanadium Slag by Sodium Roasting and Water Leaching

The extraction of vanadium and chromium from high chromium content vanadium slag by salt roasting and water leaching process has been investigated, which uses mixed sodium salts (Na2CO3 and NaOH) as additive agent in roasting process. The mineralogical morphology was prospected by TG-DSC, XRD, SEM and EDS. The oxidation of slag and transversion of V/Cr-containing phase and sodium salts have been discussed. It has been demonstrated that the presence of NaOH contributes to decompose spinel and olivine phases, which is beneficial to reduce the roasting temperature and elevate V, Cr leaching ratio. The roasting parameters have been studied as a function of roasting temperature, roasting time and ratio of alkali, in which the roasting temperature is the most effective factor on the leaching rate of vanadium and chromium. Under the optimum condition, the leaching rates of V and Cr reached 95.8% and 97.6%, respectively.
