Screening for depression in cArDiovascular patients at a tertiary Centre in TrinidAd and Tobago: The SAD CAT study

Objectives This was an observational, cross-sectional study aimed to screen cardiovascular patients for depression at a tertiary center in Trinidad and Tobago; and to determine any significant associations amongst patients’ demographics, comorbidities, and cardiovascular medications with depressive symptoms. Methods Patients (n=1203) were randomly selected from the cardiology outpatient clinics at the Eric Williams Medical Sciences Complex. After meeting selection criteria, informed consent was obtained, and patients were administered a case report form, which included the Patient Health Questionnaire-9 (PHQ-9). Results The study had a 96% respondent rate, whereby the average age was 62 years old. 47.5% were male, and 52.5% were female. 90.2% of the sample had cardiovascular disease. 25% of the sample had a PHQ-9 score of ≥ 10, with 19.3% having no depressive symptoms. Females, lower levels of education and income were found to be statistically significant at risk for depression (all p-values <0.001). Comorbidities associated with depression included hypertension, prior cerebrovascular events, chronic kidney disease and chronic obstructive pulmonary disease with odds ratios (OR) and 95% confidence intervals (CI) of OR 1.988 (CI 1.414-2.797), OR 1.847 (CI 1.251-2.728), OR 1.872 (CI 1.207-2.902) and OR 1.703 (CI 1.009-2.876) respectively. Only the cardiovascular medication of ticagrelor was found to be significantly associated with depression (p-value <0.001). Conclusion 1 in 4 screened cardiovascular patients displayed significant depressive symptoms with a PHQ-9 ≥ 10. The information acquired from this study may be useful in developing screening protocols that can positively impact adherence and possibly attenuate future events. This study also highlights the importance of implementing a multidisciplinary approach to managing cardiovascular disease and screening for depression. Further studies are required to validate these findings (ClinicalTrials.gov number, NCT03863262).
Cross Sectional Study for Evaluation of Rapid Test and RT-PCR in Detection of BRV in Fecal Samples of Diarrhetic Calves in Egypt

| In the present study, forty-three fecal samples were collected between 2018 and 2020, were tested for bovine Rotavirus (RBV) by rapid commercial strip test, Ag detection sandwich ELISA and RT-PCR for screening and matching of sensitivity and specificity. Our results revealed that seven samples (7/43; 16.2%) were positive by rapid test, fourteen and ten samples were positive by Ag detection ELISA (14/43; 32.5%) and RT-PCR (10/43; 23.2%), respectively. Sequence analysis for one positive sample showed its complete identity with the recent BRV Egyptian strains which reassures the vaccine reliability and negates any recent virus evolution. Meanwhile, comparison between both the rapid test and RT-PCR and ELISA, the sensitivity was 50% and 71.5% respectively, while specificity was identical. In conclusions, ELISA can be considered as a simple, sensitive and reliable test for BRV detection and devoid the drawbacks of other tests.
Thermorheology and processing of polyethylene blends : macromolecular structure effects

Rheological and processing behavior of a number of linear low-density polyethylene (LLDPE)/low-density polyethylene (LDPE) blends was studied with emphasis on the effects of long chain branching. First, a linear low-density polyethylene (LL3001.32) was blended with four LDPE's having distinctly different molecular weights. At high LDPE weight fractions, DSC melting thermograms have shown three different polymer phases; two for the pure components and a third melting peak of co-crystals. Different rheological techniques were used to check the thermorheological behavior of all blends in the melt state and the effect of long chain branching. It was found that all blends are miscible in the melt state at small LDPE concentrations. The elongational behavior of the blends was studied using a uniaxial extensional rheometer, SER. The blends exhibit strain hardening behavior at high rates of deformation even at LDPE concentrations as low as 1%, which suggests the strong effect of branching added by the LDPE component. On the other hand, shear rheology was found to be insensitive to detect addition of small levels of LDPE up to lwt%. The second set of blends prepared and studied consisted of two ZieglerNatta LLDPE's (LL3001.32 and Dowlex2045G) and two metallocene LLDPE's (AffinityPL1840 and Exact 3128) blended with a single LDPE. In DSC melting thermograms, it was observed that blends with metallocence LLDPE's exhibit a single melting peak at all compositions; whereas the Ziegler-Natta blends exhibit three melting peaks at certain compositions. It was found also that the metallocene LLDPE's are miscible with the LDPE at all concentrations. On the other hand, the Ziegler-Natta LLDPE's were found to be miscible with LDPE only at small LDPE concentrations. The processing behavior of all blends with emphasis on the effects of long chain branches was also studied in capillary extrusion. The critical shear stresses for the onset of sharkskin and gross melt fracture are slightly delayed with the addition of LDPE into LLDPE. Furthermore, the amplitude of the oscillations in the stick-slip flow regime, known as oscillating melt fracture, were found to scale with the weight fraction of LDPE. Amounts as low as 1 wt% LDPE have a significant effect on the amplitude of pressure oscillations. These effects are clearly due to the presence of LCB. It is suggested that the
Influence of some environmental factors on the feijoa (Acca sellowiana [Berg] Burret): A review

Climatic alterations affect the physiology, growth and production of the feijoa, a native plant to the higher zone between Brazil, Uruguay, Paraguay and Argentina. In Colombia, optimal growth temperatures are between 13 and 21°C (16°C). Very high temperatures (>32°C) affect pollination and fruit set, but low temperatures down to -4°C in adult plants do not cause significant damage. Thus, feijoa is a well-adapted plant to cold conditions since 3.04°C has been found as the base (minimum) temperature for the phase between flower bud and fruit set, while 1.76°C was measured as the base temperature for fruit development. The plant requires a minimum of 1000 hours of direct sunlight/year (optimum≥1500); the pyramidal form of the tree favors the entry of light into the crown organs. In the crown of a feijoa tree, trained with three branching levels of horizontal bent primary laterals, the outer middle quadrant produces the largest fruits, compared to those that grow in the upper quadrant. The reduced fruit growth is due to the excessive incidence of light (especially UV) and heat on these fruits on the periphery of the tree. In Colombia, altitudes between 1800 and 2700 meters above sea level (m a.s.l.) are adequate for growth and production of this fruit, while lower elevations favor the incidence of fruit flies. Precipitations between 700 and 1200 mm/year (max. 2000 mm) benefit the vegetative and reproductive performance of the tree, with an important drier season at the beginning of the reproductive season (flowering and fruit set). Due to the strength of its branches and the small, thick leaves, the tree is relatively wind resistant.
Why Ask Why

There is a strong case to be made that the goal of science is to develop explanatory theories that help us organize our understanding and make predictions about the natural world. What then, is the goal of science education? What is it that we want students to know and be able to do, and how do we achieve these goals? Here, I argue that one overarching goal is to help students construct causal, mechanistic explanations of phenomena. In chemistry this means we are working to help students use their understanding of molecular level interactions to explain and predict macroscopic events. Furthermore, while constructing explanations is an important goal in itself, the very act of constructing explanations helps students develop a deeper understanding, and provides the kind of intellectual satisfaction that memorizing facts cannot. I hope to convince you that our current approaches to assessing student learning are, in fact, all too often counterproductive and almost certainly contribute to students’ inability.
Semi-closed cycle O2/CO2 combustion gas turbines: Influence of fluid properties on the aerodynamic performance of the turbomachinery

Many gases, including carbon dioxide and argon, have been considered as alternatives to air as working fluids in a number of design studies for closed and semi-closed gas turbine engines. In many of these studies, it has been assumed that if the gas constant R and specific heat ratio (isentropic exponent) γ are included in the speed and flow parameters, the compressor map or turbine characteristic is applicable to other working fluids. However, similarity arguments show that the isentropic exponent itself is a criterion of similarity and that the turbomachinery characteristics, even when appropriately non-dimensionalized, will in principle vary as the γ of the working fluid varies. This paper examines the effect of γ on turbomachinery characteristics, mainly in terms of compressors. The performance of a centrifugal compressor stage was measured using air (γ = 1.4), CO2 (γ = 1.29), and argon (γ = 1.67). For the same values of the non-dimensional speed and mass flow, the pressure ratio, the efficiency, and the choking mass flow were found to be significantly different for the three test gases. The experimental results have been found to be consistent with a CFD analysis of the impeller. Finally, it is shown that the changes in performance can be predicted reasonably well with simple arguments based mainly on one-dimensional isentropic flow. These arguments form the basis for correction procedures that can be used to project compressor characteristics measured for one value of γ to those for a gas with a different value.Copyright © 2002 by ASME
Stress factors in persons with intellectual disabilities in different types of housing

Introduction. Type of housing is of great importance for the overall quality of life and general psychosocial well-being of persons with intellectual disabilities, as evidenced by the results of numerous studies showing that people with intellectual disabilities living in institutions have a lower level of life satisfaction compared to those living in the open community. Material and Methods. In order to determine the levels of experienced stress related to the type of housing in people with intellectual disabilities, we carried out a study including 122 persons with intellectual disabilities living in different types of housing; in institutions (n = 51), with families (n = 38), and in the supported housing program (n = 33). The Life Stress Inventory was used for the purpose of this research. Results. The results showed that people who were included in the supported housing program experienced the least stress, compared to the subjects who lived with their families or in institutions (p < 0.001). Stress was the least prevalent in the supported housing program, but the other two groups had similar results. The presence of stress did not differ significantly between subjects living with their families and those living in institutions. Conclusion. We can conclude that subjects living in supported housing experienced significantly less stress compared to the other two groups. Different types of housing were associated with different levels of stress. Overall, negative interpersonal relationship was identified as the stress factor that correlated most significantly with other stress factors.
Comprehensive Analysis of Differentially Expressed Long Noncoding RNA-mRNA in the Adenoma-Carcinoma Sequence of DNA Mismatch Repair Proficient Colon Cancer

DNA proficient mismatch repair colon cancer (pMMR CC) is the most common subtype of sporadic CC. We aimed to investigate the role of long noncoding RNAs (lncRNAs) in pMMR CC carcinogenesis. In the present study, we conducted transcriptomic analysis of lncRNAs-mRNAs in five low-grade intraepithelial neoplasia (LGIN), five high-grade intraepithelial neoplasia (HGIN), four pMMR CC, and five normal control (NC) tissues. Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment pathway, and coexpression network analyses were performed to elucidate the functions of lncRNAs and mRNAs as well as their interactions. Quantitative real-time polymerase chain reaction (qRT-PCR) was used to validate five dysregulated lncRNAs in a large set of colon tissues. Receiver-operating characteristic (ROC) curves were employed to evaluate the performance of the candidate lncRNAs. A set of 5783 differentially expressed lncRNAs and 4483 differentially expressed mRNAs were detected among the LGIN, HGIN, pMMR CC, and NC samples. These differentially expressed lncRNAs and mRNAs were assigned to 275 significant GO terms and 179 significant KEGG enriched pathways. qRT-PCR confirmed that the expression of five selected lncRNAs (ENST00000521815, ENST00000603052, ENST00000609220, NR_026543, and ENST00000545920) were consistent with the microarray data. ROC analysis showed that four lncRNAs (ENST00000521815, ENST00000603052, ENST00000609220, and NR_026543) had larger area under the ROC curve (AUC) values compared to serum carcinoembryonic antigens, thereby distinguishing NC from pMMR CC. In conclusion, several lncRNAs play various roles in the adenoma-carcinoma sequence and may serve as potential biomarkers for the early diagnosis of pMMR CC.
MODERATING EFFECT OF TECHNOLOGY READINESS ON ADOPTION OF GEOTAGGING TECHNOLOGY AMONG SOCIAL NETWORKING SITES (SNSS) USERS FOR SMART TOURISM

More recently social networking sites (SNSs) users are extensively using the emerging geotagging technology for tourism motivation. The study aims to examine the relationship between determinants of geotagging technology and intention to adopt geotag technology as well as the extent to which technology readiness moderates the link between determinants of geotagging technology and intention to adopt geotag technology. Data were collected from a sample of 356 university students by using convenience sampling technique. Partial least square structural equation modelling has been used to measure the results. The empirical outcome uncovers that social influence, performance expectancy and facilitating condition are the factor that have direct impact on SNSs user’s willingness to adopt geotag for smart tourism experience. The present paper enriches UTAUT model by understanding the association between two variables namely effort expectancy and performance expectancy as well as the moderating role of the technology readiness. The findings of the study will assist to SNSs service providers by understanding the moderating role of technology readiness in the relationship between determinants of geotagging technology and intention to adopt geotag technology.

The results of this research were in agreement with the available literature data, showing no sig nificant difference in morphometric analysis of the plantar spurs between sexes. Future researches should include data regarding the age, body weight, and comorbidities among examinees.
An in-situ X-ray absorption spectroelectrochemical study of the electroreduction of uranium ions in HCl, HNO3, and Na2CO3 solutions

Abstract A spectroelectrochemical cell was fabricated for in-situ X-ray absorption spectroscopy (in-situ XAS). The XAS spectra of the uranium LIII edge were monitored in electrolyte solutions during the electrochemical reduction. Tetravalent uranium, U4+, in 1 mol dm–3 (M) hydrochloric acid (HCl) was electrochemically prepared from hexavalent uranium, UO22+, by constant current electrolysis, and the extended X-ray absorption fine structure (EXAFS) was analyzed. The concentration ratio of UO22+ and U4+, which were formed via the disproportionation of pentavalent uranium, UO2+, during the electrolysis, were calculated based on the intensity of the signal for the two axial oxygen atoms in the linear UO22+ unit, the U–Oax, bond that had a radial structural function. The apparent redox potential of the UO22+/U4+ couple in 1 M HCl was determined based on the Nernst equation using the concentrations of UO22+ and U4+. The electrode potential was shown to be close to the formal potential of the UO22+/UO2+ couple as reported previously. This result indicates that the UO2+ that was formed electrochemically at the electrode disproportionated to form UO22+ and U4+ in the bulk solution. The in-situ XAS of UO22+ in 0.1 M nitric acid was also performed. The U4+ that formed was partially re-oxidized to UO22+ by the NO3– present in the solution. The formation of the UO2+ carbonato complex was observed by in-situ XAS in a 1 M sodium carbonate solution during the bulk electrolysis. The edge jump of the X-ray absorption near edge structure (XANES) spectrum shifted from 17.164 to 17.163 keV, and the bond distances of U–Oax and U–O for CO32– increased from 1.78 to 1.88 Å and from 2.42 to 2.53 Å, respectively, because of the reduction of the UO22+ to the UO2+ carbonato complex.
DETERMINANT FACTORS OF STUNTING AND EFFECTIVENESS OF NUTRITION, INFORMATION, EDUCATION INTERVENTIONS TO PREVENT STUNTING IN THE FIRST 1000 DAYS OF LIFE: A SYSTEMATIC REVIEW

ABSTRACT Background: In the world, stunted children reach 155 million, with a 23% stunting prevalence. Asia as a whole is the most heavily stunted region in the world. In Asia, the prevalence of stunting was 56% in 2016. In 2019, the world’s number of stunted children reached 144 million, or 21.3%. Stunted children will experience neurological problems in the first 1000 days of life. This study aimed to systematically review the determinants factors of stunting and effectiveness of nutrition, information, education interventions to prevent stunting in the first 1000 days of life. Subjects and Method: This was a systematic review study. Articles selected in this study were published in the PubMed database from January 2010 to January 2020. The articles were collected by following the Preferred Reporting Items of Systematic Reviews and Meta-Analysis (PRISMA). Results: Determinant factors of stunting in developing countries and low-middle income countries were 1) feeding practice; 2) culture and ethnicity; delayed in carrying out early initiation of breastfeeding and complementary feeding of breast milk; 3) lack of knowledge and understanding of mothers about complementary breastfeeding and infant diet; 4) family planning practice; 5) birth spacing; 6) vaccination; 7) and parent’s education. Conclusion: Handling stunting in the first 1000 days of life is a priority at the national and global levels. Efforts to handle and prevent stunting problems through increasing maternal nutrition knowledge can be done by providing information or health messages related to nutrition, from a person or institution to the community as message recipients through certain media Keywords: determinant, intervention, golden age, stunting Correspondence: Basri Aramico.

Characterization of upper troposphere water vapor measurements during AFWEX using LASE.

Water vapor profiles from NASA's Lidar Atmospheric Sensing Experiment (LASE) system acquired during the ARM/FIRE Water Vapor Experiment (AFWEX) are used to characterize upper troposphere (UT) water vapor measured by ground-based Raman lidars, radiosondes, and in situ aircraft sensors. Initial comparisons showed the average Vaisala radiosonde measurements to be 5-15% drier than the average LASE, Raman lidar, and DC-8 in situ diode laser hygrometer measurements. They show that corrections to the Raman lidar and Vaisala measurements significantly reduce these differences. Precipitable water vapor (PWV) derived from the LASE water vapor profiles agrees within 3% on average with PWV derived from the ARM ground-based microwave radiometer (MWR). The agreement among the LASE, Raman lidar, and MWR measurements demonstrates how the LASE measurements can be used to characterize both profile and column water vapor measurements and that ARM Raman lidar, when calibrated using the MWR PWV, can provide accurate UT water vapor measurements.
