Authors: Valdés Reyna Jesús , Espinoza Aburto Javier 
Published: January 2024

No obstante que la familia de las gramíneas tiene una gran importancia para la industria pecuaria, particularmente en zonas áridas y semiáridas, no se han realizado trabajos tendientes a conocer los patrones de su distribución en el Estado de Coahuila.
El presente estudio corológico pretende describir y analizar los patrones de distribución de las especies de gramíneas para el Estado de Coahuila, utilizando los registros de colecta disponibles en el herbario de la Universidad, así como en otras fuentes. Cada una de las colectas reportadas se ubicó en 11 unidades geográficas de estudio, en que se dividió el Estado de Coahuila, según las condiciones edafoclimáticas y fisiográficas.
Mediante el uso de técnicas de análisis de conglomerados, ordenación polar y arreglo tabular, se compararon inicialmente cada una de las unidades en función a su composición de especies y, posteriormente, cada una de las especies en base a las unidades en las cuales se presentan, tanto dentro como fuera del Estado. Se concluye que la distribución de la flora de gramíneas de Coahuila, se conforma al patrón de variación edafoclimática del Estado, en el que la fisiografía juega un papel relevante, y que puede visualizarse como una amalgama de elementos discretos, cuya distribución permite suponer que el origen y diversificación de esta flora data de épocas antiguas.

Published: January 2024

Background: Sexology training and a tolerant attitude towards sexuality are key for nurses to be able to approach the topic appropriately at work. Therefore, the main goal of this study is to determine whether sexology training as part of the nursing degree affects students’ attitudes towards sexuality.Method: A case-control study was performed on 127 students and postgraduates from Facultad de Enfermería de Gijón, dividing the sample in two groups according to their attendance to specific sexology training. The attitudes were assessed using a translated version of Trueblood Sexual Attitude Questionnaire, and data analysis was performed using SPSS software.Results: There are statistically significant differences (p= 0.015) between the mean total score from the group that had received the training (6.53 ± 0.81) and the mean total score from the group that hadn’t (6.13 ± 1.06). Attitudes from members of both groups were more open towards other people’s behaviour (7.53 ± 0.76 versus 7.25 ± 1.06) than towards their own (5.54 ± 1.03 versus 5.00 ± 1.28), respectively.Conclusions: It is verified that receiving sexology training correlates with more liberal attitudes towards sexuality. Only 24.8% of nursing faculties in Spain offer specific sexology courses.
Introducción: Tener unas actitudes tolerantes hacia la sexualidad, junto con la formación en sexología son aspectos clave para favorecer el abordaje de la sexualidad en la práctica profesional de las enfermeras. Por ello, el objetivo principal de este estudio fue comprobar si recibir formación en sexología durante los estudios de Grado en Enfermería influye sobre las actitudes hacia la sexualidad del alumnado.Método: Se realizó un estudio caso-control en 127 estudiantes de la Facultad de Enfermería de Gijón, dividiendo a la muestra en función de si habían recibido o no formación específica en sexología. Para medir dichas actitudes se utilizó una versión adaptada al castellano del Trueblood Sexual Attitude Questionnaire (TSAQ), analizándose los datos mediante el programa SPSS.Resultados: Existen diferencias estadísticamente significativas (p=0,015) entre la puntuación media total obtenida en el TSAQ por los estudiantes que sí habían recibido formación en sexología (6,53 ± 0,81) comparada con los que no (6,13 ± 1,06). De igual modo, las actitudes de las personas integrantes de ambos grupos son más liberales para los comportamientos ajenos (7,53 ± 0,76 frente a 7,25 ± 1,06) que para los propios (5,54 ± 1,03 frente a 5,00 ± 1,28), respectivamente.Conclusiones: Se verifica que recibir formación en sexología se relaciona con la tenencia de unas actitudes hacia la sexualidad más liberales. Sólo un 24,8% de las Facultades de Enfermería españolas ofertan asignaturas específicas en sexología.

Published: January 2024

Asrama DLH Jagakarsa has a communal wastewater treatment plant (WWTP) that produces sludge that has not been treated. Asrama DLH residents directly apply the sludge from the communal WWTP as fertilizer for plants. Fecal sludge contains organic substances that provide nutrients to plants. However, there is a possibility that it still contains pathogenic bacteria and metals that can be harmful to plants. This research aims to utilize the fecal sludge from Asrama DLH Jagakarsa WWTP as organic fertilizer with additional ingredients in the form of humic acid. During fertilizer manufacturing, the bacteria and metals are removed. The analysis used includes the composting process conditions analysis, characteristics tests to determine the content of feces and fertilizers, and analysis of the application to plants. Analysis of the conditions in the composting process is the analysis of the pH value of organic fertilizers. Characteristic tests include soil variation (V1), WWTP sludge (V2), and organic fertilizer (V3). Analysis of the application of plant growth was carried out by testing the variation of soil 100% (P1), soil 80% + 20% fecal sludge (P2), and soil 80% + 20% organic fertilizer (P3). The laboratory analysis includes the analysis of nitrogen, phosphorus, potassium (NPP), and water content which will be compared with the quality standard of the Decree of the Minister of Agriculture Number 261 of 2019. The plant that is used as an indicator of the success of organic fertilizer in plant growth is the kale plant. The best value was obtained in the variation of organic fertilizer (V3), namely the NPP content and water content, respectively, which were 4.52%, 2.57%, 0.05%, and 19.84%. This shows that organic fertilizer increases NPP elements and plant growth.

Background: The purpose of this research was to assess dental students' opinions on professionalism teaching and behaviors in their clinical experience during their student years in order to improve the establishment of a curriculum in professionalism for dental students in the Twin Cities of Rawalpindi and Islamabad, Pakistan.
Materials and Methodology: The cross-sectional cohort questionnaire-based study assessed 3rd and 4th year BDS students' professionalism using a "Climate of Professionalism" survey over a 6-month period. In the first section, students evaluated the frequency of 11 clinical behaviors as "rarely," "occasionally," or "mostly." The second section gathered feedback on 10 professional behaviors taught by instructors, scored as 1, 2, or 3. Demographic data like mean age, year percentages, and gender ratio were collected. Descriptive analysis was conducted. Total scores for all participants were added and the responses were compared between 3rd and 4th-year students, and significance was set at p < 0.05.
Results: For each academic year, the mean total scores of participants' assessments of the professional conduct of dental students, residents, and professors were close to 70% of the total maximum score. The mean overall scores of participants who evaluated the professionalism of faculty members' teaching and modeling behaviors were almost 80% of the maximum score of 30. Comparing results with studies worldwide, the ratings fared similar to peer researches.
Conclusion: The study highlights the current state of professionalism in the dental teaching institutes of Rawalpindi and Islamabad. Positive ratings, at 70% and 80%, reveal opportunities for further analysis and potential nationwide research. These findings suggest alignment with global professionalism trends thus facilitating the establishment of a standardized professional culture, improving patient responses, and strengthening trust between practitioners and patients.

Authors: Kishore Aditi , Pal Bodhisattya , Sarkar Priyanka 
Published: January 2024

The Camelidae family includes the Old-World camelids, represented by the Dromedary (one-humped) camel (Camelus dromedarius) and Bactrian (two-humped) camel (Camelus bactrianus), as well as the New-World camelids, also known as South American camelids (SACs), which consist of Llama (Lama glama), Alpaca (Lama pacos), Guanaco (Lama guanicoe), and Vicuña (Vicugna vicugna). Known for their resilience, camelids exhibit specialised anatomical, physiological, and behavioral adaptations that enable them to thrive across a spectrum of challenging environments—from arid deserts to the elevated Andean highlands. Apart from being an intertwined part of cultural heritage, camelids emerge as vital economic contributors for local communities, providing invaluable resources such as fibre, milk, and meat, thereby playing a central role in the economic well-being of these regions. Amidst the escalating effects of climate change, with conventional agriculture and livestock production becoming virtually impossible, these miracle species are emerging as the centrepiece of global interests. This paper aims to promote awareness of the crucial roles played by camelids by investigating their inherent connection with the traditions and heritage of indigenous communities while also examining their contribution for ensuring sustainable economic growth and food security.

Published: January 2024

Rice (Oryza sativa L.) is one of the most important cereal crops. Increasing rice production is constrained by various stresses and drought is one of the major limiting factors. For future food security, assessments of genetic resources are necessary. Indigenous varieties contain a high level of genetic diversity and can serve as potential genetic resources for improving yield, and resistance to various biotic and abiotic stress conditions. The present investigation was conducted in the Biotech Hub, Biswanath College of Agriculture, AAU, Biswanath Chariali during 2022-23. In this study, the genetic diversity of 27 indigenous rice germplasm using SSR markers was assessed. Out of the total 28 SSR markers screened, 17 were found polymorphic across twenty-seven genotypes with PIC values ranging from 0.076 to 0.499. The genetic diversity was estimated by the Jaccard dissimilarity coefficient. The phylogenetic tree, using unweighted neighbor-joining (UPGMA) drawn from the analysis divides 27 genotypes into 3 clusters. Nine genotypes were further characterized by exposure to drought stress compared to the control condition. Plants were grown in PVC pipes and subjected to drought by withdrawing water at 45 days after showing (DAS) for 25 days. A comparative study was done for a few morphophysiological parameters i.e. root length, root biomass, root-shoot ratio, root length density, chlorophyll content etc. It was observed that genotype Dehangi followed by N22 and Shahabhagi showed the best performance for all parameters under drought stress. This information will help in the selection of varieties with better root characteristics for drought tolerance in future breeding programs.

Published: December 2002

AbstractThe electrochemical deposition of Au/Co multilayers into 20 μm‐thick ion track etched polycarbonate membranes with pore diameters of 110–150 nm was studied in a single electrolyte containing cobalt sulfate, gold cyanide, and citric acid. Cyclic voltammetry, chronoamperometry, and pulse‐potential experiments were used to determine the deposition conditions for pure Au and 98 wt.‐% Co layers. The Co‐rich metallic nanowires were deposited at –1100 mV and the Au nanowires at –490 mV vs. Ag/AgCl. Under open‐circuit conditions an Au‐displacement reaction occurred. Open‐circuit conditions were applied in combination with a steep ramp between the Co and Au potential pulses to avoid the otherwise severe Co dissolution when the potential was switched to less negative values. Scanning and transmission electron microscopy of the deposited multilayered nanowires revealed dense and well‐defined layer interfaces. X‐ray diffraction investigations of 20 μm long Au and Co nanowires showed that the Au deposits exhibit a face‐centered cubic (fcc) <111> texture, while the Co deposits exhibit a hexagonal close‐packed (hcp) (002) structure. The magnetic measurements of 12 nm Co/4 nm Au nanowires for fields applied parallel and perpendicular to the film plane indicate a low remnant magnetization.

Published: December 2002

AbstractThe Hansch analysis method was applied to a series of recently synthesized nifedipine analogues containing nitroimidazolyl, phenylimidazolyl, and methylsulphonylimidazolyl groups at the C‐4 position and different ester substituents at C‐3 and C‐5 positions of the dihydropyridine ring. Hydrophobic, electronic, inductive, and resonance substituent constants were used.The effect of these parameters on the biological activity of 1, 4‐dihydropyridines (calcium channel antagonist activity in Guinea‐pig ileal cells, log (1/IC50)) was determined by multiple linear regression analysis. Linear and quadratic relationships were obtained between the activity and these parameters. Itwas found that both electronic and hydrophobic interactions occur between the nifedipine analogues and the receptor.
Chiral Relay: A Novel Strategy for the Control and Amplification of Enantioselectivity in Chiral Lewis Acid Promoted Reactions
Authors: Corminboeuf Olivier , Quaranta Laura , Renaud Philippe , Liu Mei , Jasperse Craig P. , Sibi Mukund P. 
Published: December 2002

AbstractChiral Lewis acid catalysis has emerged as one of the premiere method to control stereochemistry. Much effort has gone into the design of superior ligands with increasing steric extension to shield distant reactive sites. We report here an alternative and complementary approach based on a “chiral relay”. This strategy focuses on the improved design of achiral templates which may relay and amplify the stereochemistry from ligands. The essence of this strategy is that the chiral Lewis acid would effectively convert an achiral template into a chiral non‐racemic template. This approach combines the advantages of enantioselective catalysis (substoichiometric amount of the chiral inducer) with the ones of chiral auxiliary control (efficient and predictable stereocontrol).
