The role of visuals in the perceptions of risk and of self-efficacy and the behaviors towards the pandemic of Covid-19

The Covid-19 has spread rapidly, becoming a global health crisis. In crises, especially in public health problems such as a pandemic, it is important to reach the target audience effectively. In this process, the use of visuals helps to convey risk messages effectively. To control the pandemic and prevent its spread, individuals’ risk perception, self-efficacy and behaviors towards the pandemic are of great importance. The aim of this study is to measure how the visuals those individuals are exposed to about the Covid-19 pandemic affect their perceived risk level and self-efficacy, and how these relationships direct their behavior towards the pandemic. For the implementation of the study, data were collected from 410 people working in public institutions, in Türkiye. Structural equation modeling, t-test and Anova techniques analyzed the data collected in the survey conducted in the survey model. According to the research results, gender and educational status significantly affect employees’ attention to visuals and risk perception. According to the results of the research model, the research factors affect each other positively. Individuals’ interest in visuals increases their perceived risk and self-efficacy perceptions. Perceived risk and self efficacy for the epidemic, on the other hand, affect their behavior towards the epidemic.

Agronomic performance and farmers' preferences of twelve spring rice genotypes under participatory approach at Kailali, Nepal

The purpose of this paper was to assess the agronomic performance and farmers’ preferences of spring rice genotypes in collaboration with farmers. This experiment was conducted from February to June, 2023 at Khaira, Bhajani Municipality in Farmer’s Field School. The experiment was laid out in Randomized Complete Block Design (RCBD), with three replications, testing twelve rice varieties involving 37 small holder farmers. The individual plot size was 10m × 2m with plant spacing maintained at 20cm × 20cm. The data were analysed using the ANOVA technique in R-Studio software (version 4.0), and Fisher’s Protected LSD test was applied for mean separation. Results revealed that yield and yield attributes along with days to maturity were statistically different among genotypes. Maximum grain yield was found in Chaite-5 (10.75 t/ha) followed by IR16L1831 (10.33 t/ha) which was statistically at par with genotype IR10L118 (10.07 t/ha), while the lowest yields were obtained in Chaite-4 (5.77 t/ha) followed by local check variety Chaini-Local (6.77 t/ha). The findings showed that SVIN-191 (139 days) and Hardinath-5 (138 days) had the highest duration to reach maturity. In contrast, the Chaini-Local variety had the shortest time to maturity, taking only 113 days, while Chaite-4 and IR10L152 required 119 and 122 days, respectively. On participatory varietal selection, the farmer preference score was found maximum in genotype IR10L152 (0.055) followed by a popular variety Chaite-5 (0.047) which signifies these genotypes have certain traits of farmer preference. Moreover, the preference for the genotype IR10L152 above the high-yielding variety Chaite-5 indicates that the farmers in Kailali took several desirable traits into consideration for rice variety selection rather than just high yield.

Statistical significance of the influence of nano-TiO2 on WPC, PPC, and OPC cement mortars

Durability of cement mortars and concrete is of significant importance in the field of concrete technology. Self-cleaning ability affects durability of cementitious compositions wherein Nano TiO2 (NT) is widely utilized in research worldwide as a popular photocatalyst. In this study, NT was applied to the cement mortars in three methods: intermixed (IM), fresh cast coat (FC), and hardened coat (HC) to three types of cements and the color removal efficiency of each combination is identified. ANOVA technique was used to analyze and understand the significance of the variance in color removal efficiency with respect to change in the dosage of NT, type of cement and NT application method. The variance analysis results suggest that White Portland Cement (WPC) exhibits increased variability in color removal efficiency, the Portland Pozzolana Cement (PPC) stabilizes at higher dosages, and Ordinary Portland Cement (OPC) demonstrates an initial increase followed by a decrease in variability. Across all the combinations, the NT dosage had a significant impact on the color removal efficiency, while the cement type did not significantly affect it. The type of NT application method significantly affected the color removal efficiency among all dosages and cement types, OPC having a greater effect than the other cement types.

Discovery of the synergy between sulindac and NO expands the application of NSAIDs in cardiac complications

Cardiac inflammation, a pathological cornerstone in cardiac dysfunction, triggers diastolic impairment, leading to profound myocardial hypoxia. This hypoxic state serves as a potent stimulus for the amplification of inflammatory mediator release, ultimately limiting the therapeutic potential of monotherapies. To address this challenge, compounds that integrate non-steroidal anti-inflammatory drugs (NSAIDs) with nitric oxide (NO) donors was synthesized. The in vitro screening unveiled the remarkable anti-hypoxic inflammatory injury activity of a sulindac derivative, despite its suboptimal COX-2 inhibition when comparing with other NSAIDs derivatives. This revelation propelled us to delve deeper into the intricate synergistic relationship between sulindac and NO. Employing two-way ANOVA and high-throughput screening technique, we incontrovertibly confirmed their synergism. Further, the underlying mechanism was unmasked through the detection of signal molecule release levels and western blot analysis. In a definitive step, we evaluated the therapeutic effects of sulindac and its derivatives in vivo, leveraging a rat model that recapitulates cardiac inflammation coupled with hypoxia. Our findings herald a promising drug candidate and establish a foundation for the expanded utilization of NSAIDs in the intricate landscape of cardiovascular diseases.

Assessing changes in intra- and inter-annual precipitation variability using advanced statistical inference techniques

ABSTRACT Aiming to find statistically significant changes on the usual monthly weather conditions in Alentejo, Portugal, in the past 40 years, time series of precipitation from a grid of locations in Alentejo were studied using an unconventional approach. The time series were divided into 4 decades and disposed in contingency tables with two factors, Year and Month. Then, log-linear models were fitted to those tables. The model deviances for Year and Month represent the weight of each factor in explaining precipitation variability and Year:Month deviance is an estimate of the lack of independence between both factors, representing changes in intra-annual precipitation variability. The set of all the models deviances, per decade and location, were analysed using ANOVA techniques, first to compare the four decades, then to perform a crossed comparison between decades and between four pre-defined zones. Results indicate significant differences between the oldest and recent decades in terms of intra-annual precipitation variability, which could be interpreted as a trend towards softening the differences in precipitation between the wet months of the year. Furthermore, two homogeneous sub-regions could be defined in Alentejo, a large interior region and a smaller one close to the Atlantic Ocean.
