Abstract

 A solution culture experiment was conducted to screen out a number of Bangladeshi tomato germplasms for salinity tolerance by exposed to control, 8, 12 dS/m NaCl (salt stress). Salinity tolerance of tomato germplasms were evaluated with respect to salinity tolerance index, shoot and root dry matter production, shoot Na+, K+, Ca2+ accumulation and their respective ratios. A tolerance index was calculated for every single germplasm in root, stem and leaf dry weights and in the K/Na and Ca/Na parameters of these organs. Tomato germplasms responded differently to salt tolerance. Based on the salinity tolerance index caused by the NaCl treatment “BT14 (BARI Tomato 14)” and “BHT5 (BARI Hybrid Tomato 5)” were found to be most tolerant germplasms to salinity with highest salinity tolerance index, root-shoot dry matter production, accumulation of K and Ca and exclusion of Na. Thus, “BT14” and “BHT5” can be regarded as a breeding material for development of new tomato varieties for tolerance to salinity.Key words: Tomato germplasms, salinity, tolerance index, dry matter, Ion concentration

Abstract

In the modern world, wireless technology is one way to send information from one place to another. This technology is getting better and better with time, which significantly impacts the activities that make up daily living. This wireless application has the most impact on mobile and other technologies. This research paper shows the design and analysis of a 3.5 GHz microstrip patch antenna (MPA) for wireless applications. The substrate material is Roggers RT/duroid, which has a dielectric permittivity of 2.2 computer simulation technology (CST) software does antenna design and simulation. Some observed parameters are the S-parameter, antenna directivity gain, voltage standing wave ratio (VSWR), and bandwidth. From the simulation, the return loss, VSWR, directivity gain, and bandwidth are -50.4227, 1.0061, 7.43 dBi, and 122.1 MHz respectively. This study aims to find the best return loss, get the most directional gain, and get the VSWR closer to 1. When this antenna was used, the results were better than those in scientific journals and conferences. As a result, this antenna is anticipated to fulfill the requirements of various wireless communication applications effectively.

Abstract

Aims: The study was carried out to identify the importance of environmental conservation, the role of Islamic law in protecting the environment, investigate whether it is possible to protect the environment by following Islamic rules. Study design: This study employs a mixed-methods approach, combining quantitative and qualitative data collection and analysis methods. Place and Duration of Study: The study was conducted in Bangladesh, with data collection primarily taking place from 01 January 2023 to 31 October 2024.Results: Out of 300 participants, 150 environmentalists and 150 Islamic thinkers were surveyed. Among environmentalists, 77% believed Islamic principles significantly aid environmental protection, with a chi-square test confirming a strong association (p < 0.05). Islamic thinkers unanimously supported the role of Islam in conservation, emphasizing awareness campaigns. Regarding waste management, 75% favored recycling, 66.75% reduction, 58.3% reuse, and 33.3% recovery, highlighting the 4r strategy's importance. These findings underline the relevance of Islamic teachings in promoting sustainable practices and addressing environmental challenges in Bangladesh. Conclusion: In conclusion integrating Islamic principles into environmental conservation can reduce resource misuse, mitigate environmental degradation, and promote sustainable practices, aligning with both ecological and ethical objectives. While the study highlights the potential of Islamic teachings in environmental protection, further research is needed to validate and optimize their practical application in modern environmental management.

Abstract

The present work aims at assessing vegetation patterns and of the recovery process over the long term (2006 to 2025) in the Sundarbans mangroves based on the NDVI and SAVI. Landsat 5 TM and Landsat 8 OLI surface reflectance images were processed in Google Earth Engine to derive seasonal composites for the dry season (December–February). A supervised classification method was used to delineate five land-cover classes, namely water bodies, bare soil, sparse, intermediate, and dense vegetation. Accuracy assessment was carried out by visual interpretation of the sample points by using Google Earth Pro where overall accuracy was in the 88–93% over the entire study period. In 2006, dense vegetation was the most dominant (~68%) and sparse and intermediate other categories had low frequency and water bodies covered 21% of plots. For post-Sidr in 2008, nearly all plants showed more severe damage (76-79%). Post-Aila (2010) data suggested continuous intermediate (46%) and sparse (25%) vegetation cover but with negligible closed canopy. During 2015, the dense vegetation recovered to 60%, and dynamic changes among dense, intermediate, and sparse vegetation areas emerged, and the area of dense vegetation was up to 67% in 2025 indicating that the long-term restoration exhibits space heterogeneity. NDVI was effective for monitoring the overall trend of large scale canopy, while SAVI was able to capture very small scale regeneration and understory growth. The findings show the impressive resilience of the Sundarbans and the significance of such key ecological processes as canopy recovery and succession, and the need for more adaptive management to improve mangrove resilience in cyclone-prone coastal areas.
