DynACof process-based model parameterization and validation for robusta coffee
No full textCoffee Arabica and Robusta are the main species for coffee production. Both these species are grown in different suitable climate. For instance, suitable environmental conditions for Robusta species are found in lowland areas of Vietnam with relatively high temperatures and precipitation. Although, this species is resilient to climate change, but the impact of climate change has been documented in the literature. Moreover, until now, models have applied water management as adaptation approach. However, no model has considered Robusta coffee cultivation under agroforestry systems. Therefore, the present study was conducted to modify the DynACof model to simulate the Robusta coffee in agroforestry systems. It is important to mention that dataset used to modify this model was obtained from Robusta coffee open sun system due to lack of information on agroforestry systems. The study was conducted in ten districts of Vietnam where the climate is highly suitable for Robusta coffee cultivation. The DynACof model was previously developed for Arabica coffee thus, our aim was to modify the model to improve its capabilities for Robusta coffee. The climate data for historical period was retrieved from European Centre for Medium-Range Weather Forecasts, Reanalysis v5 (ERA5). The statistical indicators were applied to evaluate the model performance based on observed and predicted bean yield. In most districts, the model achieved a high coefficient of determination (R2), approximately 0.5, along with low error in some districts, ranging from 8.7% to 21.5%, in districts such as Dak Song, Krong Nang, Lam Ha, Duc Trong, and Krong Buk. The D-Index indicated the reliable predictions, with most values falling in the range of 0.7 to 0.8, particularly in districts like Dak Song, Dak Glang, Krong Nang, and Chu Prong. Some districts, such as Lagari, Duc Trong, and Lam Ha, examined the high nRMSE values ranging from 29.6% to 35.5%. Thus, residual plot shows the downward trend in error distribution. On average, the model predicted a bean yield of 2,700 kg/ha in districts where the bean maturity duration was around 260 days with an optimal climatic condition.
These results demonstrate the potential of the model for evaluating the coffee yield and guiding sustainable management strategies to address the challenges posed by climate change.Coffee Arabica and Robusta are the main species for coffee production.

Genome-wide analysis of wheat calcium ATPases and potential role of selected ACAs and ECAs in calcium stress
No full textBackground:P2- type calcium ATPases (ACAs-auto inhibited calcium ATPases and ECAs-endoplasmic reticulum calcium ATPases) belong to the P- type ATPase family of active membrane transporters and are significantly involved in maintaining accurate levels of Ca2+, Mn2+ and Zn2+ in the cytosol as well as playing a very important role in stress signaling, stomatal opening and closing and pollen tube growth. Here we report the identification and possible role of some of these ATPases from wheat.Results:In this study, ACA and ECA sequences of six species (belonging to Poaceae) were retrieved from different databases and a phylogenetic tree was constructed. A high degree of evolutionary relatedness was observed among P2 sequences characterized in this study. Members of the respective groups from different plant species were observed to fall under the same clade. This pattern highlights the common ancestry of P2− type calcium ATPases. Furthermore, qRT-PCR was used to analyse the expression of selected ACAs and ECAs from Triticum aestivum (wheat) under calcium toxicity and calcium deficiency. The data indicated that expression of ECAs is enhanced under calcium stress, suggesting possible roles of these ATPases in calcium homeostasis in wheat. Similarly, the expression of ACAs was significantly different in plants grown under calcium stress as compared to plants grown under control conditions. This gives clues to the role of ACAs in signal transduction during calcium stress in wheat.Conclusion:Here we concluded that wheat genome consists of nine P2B and three P2A -type calcium ATPases. Moreover, gene loss events in wheat ancestors lead to the loss of a particular homoeolog of a gene in wheat. To elaborate the role of these wheat ATPases, qRT-PCR was performed. The results indicated that when plants are exposed to calcium stress, both P2A and P2B gene expression get enhanced. This further gives clues about the possible role of these ATPases in wheat in calcium management. These findings can be useful in future for genetic manipulations as well as in wheat genome annotation process.<br/
Intellectual capital, blockchain-driven supply chain and sustainable production: role of supply chain mapping
No full textThe production and consumption of products are held responsible for most environmental challenges and climatic changes, which adversely affect human lives and compromise the future of generations to come. Sustainable production appears as a strategic route to combat these adversities, the pursuit of which is highly challenging. In this study, we argue that Intellectual capital (IC), featured by human capital, relational capital, and structural capital, can play a dual role in improving the sustainable production of a firm. We put forward that IC contributes to sustainable production directly and indirectly through the adoption of blockchain-driven supply chain management (BCSCM). In this context, the objective of this study is to examine the impact of intellectual capital (IC) on sustainable production. The study also investigates the role of SC mapping and BCSCM in the association between IC and sustainable production. Data were collected from 289 textile firms of Pakistan and Bangladesh with the help of a designed questionnaire. The study employed CB-SEM to examine the modeled relationship. Further, PLS-Multi-group Analysis (MGA) was used for cross-country comparison of the results. The results diverge from the conventional wisdom exhibiting an insignificant direct impact of IC in sustainable production. Nevertheless, the results show a meaningful indirect effect of IC through BCSCM and SC mapping on sustainable production. Results also exhibit a significant direct impact of BCSCM on the sustainable production of a firm. The results call for consideration of IC and BCSCM in improving the sustainability of a firm

Evaluating Factors Influencing Memorization in Undergraduate Medical Students.
No full textObjectives: To evaluate the techniques used by medical students for better memo-rization and identify factors that directly or indirectly influence the process of memorization.Method: This cross-sectional study included undergraduate medical students from four public/private medical schools of Karachi. Through stratified random sampling, 400 medical students were administered a questionnaire that had been developed through focused group discussions and pre-tested on a smaller population. Data was analyzed using SPSS version 26.0 by applying Pearson’s chi square test for cate-gorical variables and Mann Whitney U test for scale variables.Results: Passion for the medical field was the key motivating factor for most the students (n=133; 33.3%). The source of motivation to study in students was related to the phase of their training at medical school, with preclinical and clinical years showing a slightly significant difference (P=0.049). Silent reading (n=203; 50.8%), intermittent power naps (n=125; 31.2%) and making notes and flowcharts (n=169; 42.2%) were the preferred memorization techniques. 46.9% (n=188) students re-quired < 4 hours of study daily and no significant difference in the number of study hours required per week was observed between the two genders and the students of preclinical and clinical years. Majority of the students considered lack of sleep (n=232; 58%) and social media (n=146;36.5%) their biggest sources of distraction.Conclusion: Desire to help humanity is the main driving force for medical students. The extensive syllabus requires dedicated number of study hours and use of memo-rization techniques suited for oneself.Keywords: Learning preference, Memorization technique, Motivation factor, Memory aid, Academic performance
