COVID-19 has assumed significant and lasting proportions worldwide. Following initial cases in the Western mesoregion, the State of Santa Catarina (SC), southern Brazil, was heavily affected as a whole by the pandemic in early 2021. This study aimed to evaluate the dynamics of the SARS-CoV-2 virus spreading patterns in the SC state through March 2020 to April 2021 using genomic surveillance. During this period, 23 distinct variants, including two VOCs (Beta and Gamma) were identified, among which, the Gamma and related lineages were predominant in the second pandemic wave within SC. However, a regionalization of P.1-like-II in the Western region was observed, concomitant to the increase in cases, mortality, and case fatality rate (CFR) index. This is the first evidence of the regionalization of the SARS-CoV-2 transmission in the and highlight the importance of tracking variants, dispersion and their impact of SARS-CoV-2 on the public health system in Brazilian states.

The Yellow River Basin (YRB), located in the northern region of China, has a fragile ecological environment. With the construction of urbanization and ecological restoration projects, the YRB LULC has undergone significant change. In this study, we used the coupled Markov-FLUS model by combining natural and social driver factors to predict and simulate the LULC of the YRB in 2030, and then the LULC transfer matrix was used to analyze the characteristics of LULC change in the YRB from 1990 to 2030. The results of the study are as follows. (1) For the simulated result of LULC compared with the same period observed result, the Kappa coefficient is 0.92, indicating the coupled Markov-FLUS model has good applicability in the YRB. (2) The LULC in the YRB shows significant spatial autocorrelation. The cropland is mainly distributed in the eastern region, which is dominated by plain; woodland is mainly distributed in the central region; grassland is mainly distributed in the northern, central, and western region; waterbody is mainly distributed in the western region; built-up land is mainly distributed in the northern, south-central, and eastern region; unused land is mainly distributed in the central, northern, and western region. (3) From 1990 to 2000, the area of cropland transferred in significantly and the area of grassland transferred out significantly; from 2000 to 2015, the area of construction land transferred in significantly and the area of cultivated land transferred out significantly; from 2015 to 2030, the amount of cropland transferred out will be large, and the conversion of each other LULC type will be not significant compared with the previous periods, and the conversion structure of LULC will tend to be stable. This study is a crucial reference value for the high-quality development of the Yellow River Basin.

Objectives: Mortality during tuberculosis (TB) remains high in Africa. The purpose of our study was to determine the incidence and predictors of death during TB treatment in Cameroon. Materials and Methods: Data of subjects aged ≥15 years were retrospectively extracted from registers in all TB diagnostic and treatment centers in the Western and Northern regions of Cameroon from 2010 to 2015. Cox regression models were used to determine predictors of death during TB treatment. Results: Of the 19,681 patients included, 12,541 (63.7%) were male and their median age (25th-75th percentile) was 34 (26–45) years. The cumulative incidence (95% confidence interval [CI]) of death during TB treatment was 8.0% (7.5–8.5%). The predictors (hazard ratios [95% CI]) of death were: Age >34 years (1.479 [1.295–1.688], P < 0.001), female sex (1.471 [1.286–1.683], P < 0.001), extra-pulmonary TB (1.723 [1.466–2.026], P < 0.001), human immunodeficiency virus infection (3.739 [3.269–4.276], P < 001]), TB treatment in the Western region (2.241 [1.815–2.768], P < 0.001), treatment before 2012 (1.215 [1.073–1.376], P = 0.002)and low body weight (1st quartile and 2nd quartile) (2.568 [2.133–3.092], [P < 0.001]) and (1.569 [1.298–1.896], P < 0.001) respectively. Conclusion: The incidence of death during TB was relatively high in the Western and Northern regions of Cameroon. Recognition of these persons at greatest risk may improve care and reduce death durinng TB treatment.

AbstractThis study reports on the physical, mechanical, mineralogical and geochemical analysis carried out on four lateritic hardpan specimens from quarries in the Bamendjou area in the Western Region of Cameroon using common prescribed procedures. The results indicate that values of the bulk density, specific gravity, total and open porosities are very variable from one specimen to another. Meanwhile, the value of the compressive strengths of both the dry and immersed specimens were also very variable from one specimen to another, with the F2 and F1 specimens having higher values than the A1 and A2 specimens. All the specimens immersed in water recorded lower compressive strengths than the dry specimens. The flexural strengths also varied from one sample to another, with the F2 specimen having the highest resistance. The X-ray diffraction patterns reveal that the major peaks were assigned to gibbsite, goethite, and hematite, while the minor peaks were assigned to kaolinite and anatase. The mineralogy and geochemistry influenced the physical and mechanical properties, with the iron rich specimens having higher values in both the physical and mechanical properties than the alumina rich specimens. The results of the compressive strengths obtained were higher than (1–4) MPa obtained in Burkina Faso and India where they have been using latertic blocks for construction. Thus the hardpans of Bamendjou can also be exploited for building purposes conveniently.

The present study investigated the time attitudes (TAs) of EFL learners and their willingness and preference to share their TAs with peers and EFL instructors. Limited research has explored willingness and preference to share their TAs —a distinct and meaningful part of their temporal perspective that encompasses their positive and negative feelings about the past, present, and future experiences of English language learning. Participants were 229 students of technical and administrative diploma programmes at a Saudi industrial college in the western region of the country. Data were collected through questionnaires. Findings indicated that (1) students’ responses differed mostly on feelings about the past; (2) participants are more willing to share their feelings with peers than with instructors; (3) students are more willing to share with both peers and instructors their combined past, present, and future experiences; (4) students prefer to share their feelings about their present experiences with peers and instructors compared to their past or future experiences; (5) students prefer to share with peers both negative and positive feelings about their past, present, and future experiences; and (6) students prefer to share only negative feelings with instructors.

Abstract The aim of this study was to report the first record of Trichodina heterodentata in banded knifefish Gymnotus carapo. Banded knifefish cultivated in the municipality of Jataí, state of Goiás, in the central western region of Brazil, experienced fish mortality rates of 3-4% per tank. Macroscopic analysis found that fish had lesions on their skin and gills. Smears of the integument and gills were confectioned and air-dried at room temperature and impregnated with silver nitrate to identify the Trichodinidae species causing the lesions. The trichodinid were identified as T. heterodentata, and their characteristics were compared to those from T. heterodentata recorded from other species of host fish. It was observed that the presence of T. heterodentata was associated with inadequate fish management, low water quality, high rates of stocking density, and inadequate nutritional management.

Abstract Sigupai is one of Aceh’s local rice that highly popular because of the distinctive scent. Sigupai is still widely grown by the farmers in the southern western region of Aceh. However, this local rice has inferior production, height plant architecture, deep age and the average of production about 4 tons ha-1. The improvement of Sigupai local rice from the agronomic character and the harvest age can be done through crosses with Yinzhan varieties that carry sd-1 genes. The study aims to analyze changes in agronomic character and fragrant gene inheritance in Sigupai/Yinzhan F2 derived. Analysis of agronomic character is carried out by observing harvest age, plant height, weight of 1000 grains, grain weight per clump and yield potential per hectare. The planting material used was F2 derivative of Sigupai/Yinzhan as many as 104 individuals planted in pots. PCR analysis was conducted to analyze the presence of fragrant genes in F2 progenies of Sg/Yz. The data was analyzed with Chi-Square analysis. The results showed 104 plant genotypes analyzed by PCR, 64.42% of F2 progenies Sigupai/Yinzhan inherited the fragrant gene. The results of analysis of agronomic character showed 62 genotypes there were 95.08% of ripening aged, 59.01% had a short stem architecture and 6 genotypes (9.83%) had a potential yield of 4,04,-5,33 tons ha-1.
