Changes in the simulation of atmospheric instability over the Iberian Peninsula due to the use of 3DVAR data assimilation

The ability of two downscaling experiments to correctly simulate thermodynamic conditions over the Iberian Peninsula (IP) is compared in this paper. To do so, three parameters used to evaluate the unstable conditions in the atmosphere are evaluated: the total totals index (TT), convective available potential energy (CAPE), and convective inhibition (CIN). The Weather and Research Forecasting (WRF) model is used for the simulations. The N experiment is driven by ERA-Interim’s initial and boundary conditions. The D experiment has the same configuration as N, but the 3DVAR data assimilation step is additionally run at 00:00, 06:00, 12:00, and 18:00 UTC. Eight radiosondes are available over the IP, and the vertical temperature and moisture profiles from the radiosondes provided by the University of Wyoming and the Integrated Global Radiosonde Archive (IGRA) were used to calculate three parameters commonly used to represent atmospheric instability by our own methodology using the R package aiRthermo. According to the validation, the correlation, standard deviation (SD), and root mean squared error (RMSE) obtained by the D experiment for all the variables at most of the stations are better than those for N. The different methods produce small discrepancies between the values for TT, but these are larger for CAPE and CIN due to the dependency of these quantities on the initial conditions assumed for the calculation of a lifted air parcel. Similar results arise from the seasonal analysis concerning both WRF experiments: N tends to overestimate or underestimate (depending on the parameter) the variability of the reference values of the parameters, but D is able to capture it in most of the seasons. In general, D is able to produce more reliable results due to the more realistic values of dew point temperature and virtual temperature profiles over the IP. The heterogeneity of the studied variables is highlighted in the mean maps over the IP. According to those for D, the unstable air masses are found along the entire Atlantic coast during winter, but in summer they are located particularly over the Mediterranean coast. The convective inhibition is more extended towards inland at 00:00 UTC in those areas. However, high values are also observed near the southeastern corner of the IP (near Murcia) at 12:00 UTC. Finally, no linear relationship between TT, CAPE, or CIN was found, and consequently, CAPE and CIN should be preferred for the study of the instability of the atmosphere as more atmospheric layers are employed during their calculation than for the TT index.
A colour-based image segmentation method for the measurement of masticatory performance in older adults

Masticatory efficiency in older adults is an important parameter for the assessment of their oral health and quality of life. This study presents a measurement method based on the automatic segmentation of two-coloured chewing gum based on a K-means clustering algorithm. The solution proposed aims to quantify the mixed areas of colour in order to evaluate masticatory performance in different dental conditions. The samples were provided by ‘two-colour mixing’ tests, currently the most used technique for the evaluation of masticatory efficacy, because of its simplicity, low acquisition times and reduced cost. The image analysis results demonstrated a high discriminative power, providing results in an automatic manner and reducing errors caused by manual segmentation. This approach thus provides a feasible and robust solution for the segmentation of chewed samples. Validation was carried out by means of a reference software, demonstrating a good correlation (R2 = 0.64) and the higher sensitivity of the proposed method (+75 %). Tests on patients with different oral conditions demonstrated that the K-means segmentation method enabled the automatic classification of patients with different masticatory conditions, providing results in a shorter time period (20 chewing cycles instead of 50).
Functional and Health Properties of Yogurt Supplemented with Green Tea or Green Coffee Extracts and its Effect on Reducing Obesity Complications in Rats

The chemical composition and sensory evaluation of yoghurt supplemented with green tea (GTE) or green coffee (GCE) extracts and its effect on reducing obesity complications in rats were investigated. Ethanol extracts were prepared from green tea and green coffee and their total phenolic compounds and identified phenolic compounds were evaluated. Results showed that the GTE and GCE have containing highly antioxidant activities. Yoghurt was prepared from low fat buffalo's milk (1.5% fat) blended with 1 % of GTE or GCE. Addition of GTE or GCE had significant effects on the chemical composition and sensory evaluation. Higher sensory scores were reported flavor for GTE and GCE yoghurt than control. It was also noticed that addition of GTE or GCE to yoghurt increased viscosity a key defensive effect on the gel-factors. Feeding of obese rats on yoghurt adding to GTE or GCE showed that significant differences reduced of weight compared to positive group. There are not found significant differences of heart weights tissue while, kidney and liver weights tissues were significant differences. Also, fed obese rats on yoghurt supplemented with GTE or GCE decreased the lipids profile comparative with positive control group and improvement of liver and kidney functions. The best treatment was observed in yoghurt adding to green coffee beans extract which had reduced value of liver and kidney function parameters followed by yoghurt adding to green tea extract. The histopathological examination observed normalized in the groups fed yoghurt supplemented green tea and coffee beans extracts. Supplemented yoghurt with green tea and coffee extracts could be increased the useful health effects of yogurt by intensifying antioxidant activity which had therapeutic effects on obese rats.
Seasonal variation of Microcystis aeruginosa and factors related to blooms in a deep warm monomictic lake in Mexico

The occurrence of cyanobacterial blooms has increased globally over the last decades, with the combined effect of climate change and eutrophication as its main drivers. The seasonal dynamic of cyanobacterial blooms is a well-known phenomenon in lakes and reservoirs in temperate zones. Nevertheless, in the tropics, most studies have been performed in shallow and artificial lakes; therefore, the seasonal dynamic of cyanobacterial blooms in deep and eutrophic tropical lakes is still under research. We studied the seasonal variation of the phytoplankton community and the factors associated with Microcystis aeruginosa blooms along the water column of Lake Alberca de Tacámbaro, a warm monomictic crater lake located in Mexico, during 2018 and 2019. According to previous studies performed in 2006 and 2009-2010, this lake was mesotrophic-eutrophic, with Chlorophyta and Bacillariophyta as the dominant groups of the phytoplankton community. During 2018 and 2019, the lake was eutrophic and occasionally, hypertrophic. The dominant species was M. aeruginosa, forming blooms at different depths, and mostly, during autumn and winter months. These findings suggest that M. aeruginosa in Lake Alberca de Tacámbaro displays seasonal and spatial population dynamics. Total phosphorus, dissolved inorganic nitrogen, water temperature and photosynthetically active radiation were the environmental factors related to M. aeruginosa blooms. Our results suggest that the changes in the structure of the phytoplankton community through time, and M. aeruginosa blooms in Lake Alberca de Tacámbaro, are mainly related to changes in land use from forest to farmland in areas adjacent to the lake, which promoted its eutrophication in the last years through runoffs. Comparative studies with other deep and eutrophic lakes will allow us to gain a deeper understanding of the dynamic of cyanobacterial blooms in natural and artificial water reservoirs strongly stressed by human activities.

Public Service Satisfaction on Hajj-Related Services in Indonesia: Demographic Analysis

Measurement of public service satisfaction with government services serves as a valuable reflecting point for public officials to improve the public service quality. Pilgrimage to Mecca and Medina in Saudi Arabia is considered as a national duty and government responsibility in countries with a significant number of Muslim citizens. This article analyzes primary data from the 2019 national public service satisfaction survey on hajj-related services within Indonesian territory collected by the Ministry of Religious Affairs to examine variation across demographic backgrounds. 1,491 respondents participated in the survey representing individual appraisals toward various services during departure and returning phases. The main focus of investigation are the six selected service dimensions, namely, 1) Individual capability, 2) Ease of access to information, 3) Service procedures, 4) Speed of service, 5) Facilities and infrastructure, and 6) Cost-related perception. The results of regression analysis support diverse roles of demographic variables in explaining variance in public service satisfaction feedback. The empirical findings suggest that people with a higher-level education are more likely to experience less satisfaction. Meanwhile, females are likely to perceive higher satisfaction with the provided services than the males.
Bidirectional Cell-Cell Communication via Indole and Cyclo(Pro-Tyr) Modulates Interspecies Biofilm Formation

Indole is a relatively stable N-heterocyclic aromatic compound that is widely found in nature. To date, the correlations between indole-related bidirectional cell-to-cell communications and interspecies communal organization remain poorly understood. ABSTRACT The extracellular signaling molecule indole plays a pivotal role in biofilm formation by the enteric gammaproteobacterium Escherichia coli; this process is particularly correlated with the extracellular indole concentration. Using the indole-biodegrading betaproteobacterium Burkholderia unamae, we examined the mechanism by which these two bacteria modulate biofilm formation in an indole-dependent manner. We quantified the spatial organization of cocultured microbial communities at the micrometer scale through computational image analysis, ultimately identifying how bidirectional cell-to-cell communication modulated the physical relationships between them. Further analysis allowed us to determine the mechanism by which the B. unamae-derived signaling diketopiperazine cyclo(Pro-Tyr) considerably upregulated indole biosynthesis and enhanced E. coli biofilm formation. We also determined that the presence of unmetabolized indole enhanced the production of cyclo(Pro-Tyr). Thus, bidirectional cell-to-cell communication that occurred via interspecies signaling molecules modulated the formation of a mixed-species biofilm between indole-producing and indole-consuming species. IMPORTANCE Indole is a relatively stable N-heterocyclic aromatic compound that is widely found in nature. To date, the correlations between indole-related bidirectional cell-to-cell communications and interspecies communal organization remain poorly understood. In this study, we used an experimental model, which consisted of indole-producing and indole-degrading bacteria, to evaluate how bidirectional cell-to-cell communication modulated interspecies biofilm formation via intrinsic and environmental cues. We identified a unique spatial patterning of indole-producing and indole-degrading bacteria within mixed-species biofilms. This spatial patterning was an active process mediated by bidirectional physicochemical interactions. Our findings represent an important step in gaining a more thorough understanding of the process of polymicrobial biofilm formation and advance the possibility of using indole-degrading bacteria to address biofilm-related health and industry issues.
Trait mindfulness weakens the relationship between Snapchat use and alcohol-related outcomes

Abstract Objective: Previous studies identified Snapchat as the most likely social media platform for depictions of excessive drinking and consequences. We sought to further examine this relationship and the possible protective impact of trait mindfulness. Method: A sample of 838 college students completed a survey assessing self-reported alcohol use, alcohol-related consequences, trait mindfulness, and individual and peer alcohol-related Snapchat posts. Results: Viewing more peer’s Snapchats was associated with increased alcohol-related consequences, except at high levels of trait mindfulness. When controlling for the individual’s Snapchat posts, the significant relationship between peer’s Snapchats and consequences remained at low levels of trait mindfulness but not for moderate levels. The protective effect of high levels of trait mindfulness endured. Conclusion: Increasing trait mindfulness may help buffer the negative influence of viewing peer’s alcohol-related Snapchats on alcohol-related consequences. Further examining how trait mindfulness interacts with peer norms offers important avenues for future research.
Global scoping review of HIV prevention research with transgender people: Transcending from trans‐subsumed to trans‐centred research

Globally, transgender populations are disproportionally impacted by HIV and effective HIV prevention interventions targeting these populations are critically needed. Such interventions require research focused on the specific needs and experiences of transgender people. This methodological review aims to determine the extent to which HIV prevention research has included transgender participants by subsuming them into non‐transgender populations, or by centring them either in comparison with other groups or as the sole focus of research.
Exploring Measures for Improving Small and Medium Construction Enterprises’ (SMCEs) Participation in the Nigerian Public Procurement

Despite the roles which small and medium construction enterprises (SMCEs) play in the Nigeria construction industry and the economy at large, extant research revealed that their participation in public procurement is poor as large firms have dominated the public procurement market. Previous studies have identified barriers responsible for their low participation and also suggested improvement measures. However, improvement measures best suited to dismantle/mitigate each barrier is not known. This study thus, assessed measures for improving SMCEs’ participation in Nigeria public procurement. The study collected data from 100 SMCEs in Nigeria, via a questionnaire survey. Mean/relative importance index was used for ranking the measures and ANOVA for checking difference between the studied measures. The result of the study revealed that E-procurement is the best measure for improving SMCEs’ participation in public procurement as it is best in dismantling barriers related to “problematic procurement procedure”, “lack of awareness of public procurement” and “legal issues/corruption”. Training which is suitable for eliminating barriers related to “lack of skilled employees and partners”, emerged as the second best followed by Division of Contract into lots that is best suitable for tackling barriers related to “lack of resources” which is contrary to previous researchers’ belief that it is the best measure. The study concludes that E-procurement, training and division of contract into lots are all suitable measures for improving SMCEs’ participation in Nigeria public procurement in their other of priority. The study’s findings show that it is desirous that the measures are applied together as none of these measures is singularly sufficient in dismantling all barriers to SMCEs’ participation in public procurement.
Dynamics of circulating dendritic cells and cytokines after kidney transplantation—No effect of remote ischaemic conditioning

Inflammation resulting from ischaemia/reperfusion injury can cause kidney graft dysfunction, increase the risk of delayed graft function and possibly reduce long‐term graft survival. Remote ischaemic conditioning may protect against ischaemia/reperfusion injury and mitigate the immunological response to the graft. We investigated the immunological effects of remote ischaemic conditioning on kidney transplantation from deceased donors in the randomized CONTEXT study. Three circulating dendritic cell (DC) subtypes identified in peripheral blood from kidney transplant recipients [myeloid DCs, plasmacytoid DCs and immunoglobulin‐like transcript (ILT)3+ DCs] were measured at baseline, days 1, 3 and 5 and 1 and 3 months after transplantation. We also quantified 21 cytokines at baseline, days 1 and 5 and 3 months after transplantation. Neither DC counts nor cytokine levels differed between patients receiving remote ischaemic conditioning and controls; however, several parameters exhibited dynamic and parallel alterations in the two groups over time, reflecting the immunological response to the kidney transplantation and immunosuppression.
Activity-Based Hydrazine Probes for Protein Profiling of Electrophilic Functionality in Therapeutic Targets

Most known probes for activity-based protein profiling (ABPP) use electrophilic groups that tag a single type of nucleophilic amino acid to identify cases in which its hyper-reactivity underpins function. Much important biochemistry derives from electrophilic enzyme cofactors, transient intermediates, and labile regulatory modifications, but ABPP probes for such species are underdeveloped. Here, we describe a versatile class of probes for this less charted hemisphere of the proteome. The use of an electron-rich hydrazine as the common chemical modifier enables covalent targeting of multiple, pharmacologically important classes of enzymes bearing diverse organic and inorganic cofactors. Probe attachment occurs by both polar and radicaloid mechanisms, can be blocked by molecules that occupy the active sites, and depends on the proper poise of the active site for turnover. These traits will enable the probes to be used to identify specific inhibitors of individual members of these multiple enzyme classes, making them uniquely versatile among known ABPP probes.
Knowledge and Practice Regarding Coronavirus Disease Prevention (COVID-19) Among Internally Displaced Persons in Camps in Central Darfur Region, Sudan

Background: The lacking healthcare system services in conflict areas and the emergence of infection with a pandemic of coronavirus disease may exacerbate the humanitarian crisis among the camp residents in the central Dafur region of Sudan. Adequate knowledge and practices are vital to prevent coronavirus disease 2019 (COVID-19). Therefore, this study aimed to investigate the knowledge and practice regarding COVID-19 among internally displaced persons in Sudan. Methods: In this cross-sectional study, data were collected through an online survey using a self-administered questionnaire. Convenience sampling method was used for the internally displaced persons in two camps of Zalingei town, central Darfur region, Sudan. Results: In total, 143 participants responded; 75 (52.4%) of them were female, while 68 (47.6%) were male; 49 (34.3%) were between the age of 50 and 60 years; 78 (54.5%) were formally uneducated; 126 (88.1%) did not have a chronic disease; and 56 (39.2%) knew about COVID-19 from their relatives and friends. The overall mean of participants’ knowledge toward COVID-19 was 3.68 (SD ± 0.60(, denoting good with a rate of 73.6% and that of the practice was 2.65 (SD ±1.08), denoting moderate with a rate of 53%. A positive correlation was seen between knowledge and practice (r = 0.700, p < 0.000). Statistically significant differences were observed between the mean score of knowledge and practice with age, education, and information sources (p < 0.0001). While graduates showed a higher knowledge (116.29, p = 0.000), secondary respondents showed a higher practice (115.04, p = 0.000) than others. Conclusion: This study suggests educational intervention and awareness programs for uneducated and older people.
Sentiment Analysis of Religious Moderation in Virtual Public Spaces during the Covid-19 Pandemic

_______________________ *Correspondence Address: unik.salsabila@pai.uad. ac.id Abstract: In Indonesia, the COVID-19 pandemic has resulted in the virtualization of most social and educational activities, including discourse on the dynamics of Islamic education, which is colored by contextual differences in manhaj, ideology, and religious practice. Social media has evolved into a new role as a multicultural public space that reflects the Indonesian people's religious literacy diversity. As a subsystem of national education, Islamic education plays a critical role in internalizing the Indonesian people's competencies. Religious moderation literacy will lead Indonesian people who are multicultural to a more accepting and inclusive attitude while reducing social conflicts. The purpose of this research is to ascertain public sentiment toward religious literacy in Indonesia during the 2020 Covid-19 outbreak. Twitter was chosen as the virtual public space to study in this context because, according to previous research, it is a social media platform widely used by Indonesians to discuss serious topics in education and religion. The researcher employs a type of quantitative exploration as a statistical testing technique. The data collection technique was crawling through open public data associated with Twitter's Application Programming Interface (API). This research generated findings in a word cloud labeling graph containing data on religious moderation participation. The sentiment analysis score obtained is 0.9183, which is higher than 0.4588 on religious moderation content. The combined score is 0.565, which is higher than 0.333. the results are also contained in a sentiment analysis heat map visualization. The researchers recommend future researchers compare the ratio of religious moderation material on Islamic religious education subjects in online learning.
High school EFL students’ beliefs about oral corrective feedback: The role of gender, motivation and extraversion

This study employed an explanatory sequential mixed-methods research design to examine the beliefs of Vietnamese EFL students concerning oral corrective feedback (CF) and the role of some individual differences in these beliefs. The data consisted of questionnaires completed by 250 Vietnamese high school students and follow-up interviews with 15 of them. Exploratory factor analysis revealed six latent factors underlying students’ beliefs about CF, namely, (1) output-prompting CF and eliciting recasts, (2) desire for CF, (3) non-verbal cues, (4) important errors, (5) input-providing CF, and (6) less important errors. Descriptive statistics and thematic analysis of the interviews showed that students were positive about CF. They liked both input-providing CF and output-prompting CF for all error types. Metalinguistic feedback was the most strongly preferred, while clarification request was the least preferred. Further statistical analyses revealed some interesting relationships between students’ beliefs about CF and their gender, English learning motivation, and self-rated introversion/extraversion. Females were more positive about CF than males, and extraverted females were more positive about input-providing CF than introverted females. Also, students learning English for exams were more positive about CF than those learning English for communication. Pedagogical implications for effective feedback provision in EFL contexts are discussed.
