This mixed-methods study examines the proposition that teachers act first as moral educators and then as subject specialists, exploring how moral instruction relates to student moral development and academic outcomes in secondary science classrooms. Guided by objectives to describe teachers’ moral-education practices, assess relationships with student ethical reasoning and academic engagement, and explore teacher professional identity, the study sampled 18 science teachers and 384 students across seven public secondary schools in West Bengal.

There is an insistent need for safer and more sustainable plant-based treatments because of the rising incidence of diabetes and the growing threat of antibiotic resistance. A traditional medicinal plant, Clitoria ternatea (butterfly pea) has drawn more scientific attention because of its abundance of bioactive substances, especially flavonoids and anthocyanins. Its dual medicinal potential as an antimicrobial and antidiabetic agent is supported by these phytochemicals.

Agriculture is highly sensitive to interannual climate variability, particularly in regions dominated by rainfed systems. This study investigates how spatio‑temporal variability in rainfall and temperature influences district‑level crop productivity using only secondary datasets and a reproducible GIS‑enabled workflow. We demonstrate a regional analysis framework (illustrated for Maharashtra State, India; easily adaptable to other regions) combining (i) gridded climate surfaces, (ii) satellite‑derived vegetation indices, and (iii) official crop statistics.

Groundwater forms the backbone of drinking water supply in the Himalayan region, rendering its quality assessment essential for long-term sustainability. This study presents a comprehensive evaluation of groundwater quality in Chamoli and Almora districts of Uttarakhand, employing physico-chemical analysis, heavy metal concentration measurements, and Water Quality Index (WQI) determination.

This study aimed to test the effectiveness of a ZnO solution mixed with an Anionic Polymer in reducing the amount of UV-C radiation that can penetrate fabric.
The solution was coated onto three types of fabric: silk, cotton, and linen, in both white and black colors. The experiment was conducted in three locations in Nan province: Phaya Phanong Stadium, the Thawangpha Meteorological Department, and the area of Somdet Phra Yupparat Pua Hospital, as well as in the hospital’s laboratory.

This study was carried out to compare the nutritional values of seven freshwater, air-breathing fish species commonly found in Assam, India. The fish included Channa punctata, Channa striata, Channa gachua, Channa marulius, Heteropneustes fossilis, Anabas testudineus, and Clarias magur. Samples were collected from the Kamrup district, and their protein, fat, moisture, ash, and carbohydrate contents were analyzed. The results showed that Channa marulius had the highest protein content at 24.94%, while Clarias magur had the lowest at 14.3%.

The present study evaluates the physico-chemical parameters of the Vaigai River at five sampling sites during August 2015 and August 2025 to understand spatial and temporal variations in water quality. Parameters including pH, electrical conductivity, total dissolved solids (TDS), alkalinity, hardness, calcium, magnesium, iron, chloride, nitrate, phosphate, fluoride, Dissolved oxygen (DO), Biological oxygen demand (BOD) and Chemical oxygen demand (COD) were analysed.

Although there is a nearly three-decade history of team teaching between NESTs and NNESTs in Korean public-school English-language courses, many Korean graduate-school teacher-trainees still lack awareness of and practice in team-teaching approaches. The aim of this research was to gain insight on what graduate-school trainees in a reading methodology course thought about the team-teaching approach of co-teaching.

The present investigation was intended to explore the effect of Daily Home Assignments in terms of retention in Science subject. Experiment was conducted on IX-class students studying in Digambar Jain Inter College, Agra. The school was selected purposively and there were total 66 IX class students (N=66) who were randomly assigned to Experimental Group (N=33) and Control Group (N=33). Tools employed were: Instructional Material based on Traditional Approach, Daily Home Assignments and Science Retention Test.

The hypothalamic-pituitary-gonadal (HPG) axis orchestrates reproductive function in vertebrates, with gonadotropin-releasing hormone (GnRH) and its receptor (GnRH-R) serving as key regulators in this endocrine cascade. In teleost fishes, including economically and ecologically significant species such as Heteropneustes fossilis (Singhi), the GnRH-GnRH-R system plays a vital role in initiating and maintaining reproductive processes. This review presents a comprehensive analysis of current research on the structure, expression, and function of GnRH receptors in H.
