Morphological features of abnormal fish specimens were compared with those of normal fish from the same location. While no marked differences were observed in meristic characters, minor changes were noted in morphometric characters, particularly in the caudal peduncle region. Specifically, the distance between the post-anal fin and the base of the caudal peduncle was shorter in the abnormal specimen (15.4 mm, 4.78% of standard length) compared to the normal specimen (48.37 mm, 11.80% of standard length). Radiographic examinations were conducted to further analyze the deformities. Potential factors contributing to the deformities include insufficient essential nutrients, variations in water quality or chemical contaminants, and genetic mutations during larval development. The study discusses these potential causes and emphasizes the importance of such research in environmental monitoring.

The API X70 pipeline steel has a very fine-grained microstructure so it has high strength and ductility. In present work, the heat treatment of API X70 steel was performed at different tempering temperature and microstructural analysis was studied. Mechanical and microstructural behavior of base metal and heat-treated API X70 steel was studied. The distinct phases such as ferrite, pearlite and some carbides that form during the heat treatment are visible in the microstructure of the heat-treated samples, XRD as well as SEM analysis of base and heat-treated specimens were performed. Major peaks of iron were observed for both base and heat-treated samples during XRD analysis. XRD analysis of API X70 steel in which maximum peak intensity was present at an angle 2Ɵ = 40.18 and 44.6. SEM analysis of base as well as heat treated API X70 steel exhibit different phases such as Acicular, ferrite-pearlite and small inclusions of carbides. Various phases such as ferrite as well as pearlite were observed for the specimen tempered at 650 °C for 3 Hours. Base metal typically exhibits acicular ferrite microstructure.

The aim of this study was to standardize the covering material and variety suitable for off season flower production. The treatments consisted of five different varieties, viz. (Banglori Local, Yellow Delight, Reagan Emperor, Regan White and Nanako), and four covering materials (viz. tarpaulin, high-density polyethylene (HDPE), black satin cloth and 50% green shade net) along with natural photoperiod that was considered as control treatment were used. The trial was replicated thrice using factorial completely randomized design. The results revealed that among the different covering materials, the highest plant height (47.05 cm), flowers per plant (32.35), flower per shoot (9.75), with least days taken for peak flowering (140.13 days), were observed under HDPE covering material.
