In this work, CdS nanoparticles were synthesized via chemical method and its activity on microorganism pathogens was investigated. X- ray Diffraction (XRD), Atomic Force Microscopy (AFM) and UV-VIS transmission spectroscopic analysis were utilized to characterize the crystalline structure, size, transmission spectra of nanoparticles. Diffraction analysis confirms the formation of cubiform and hexangular structures of nanoparticle, The AFM show the formation of combination of nanoparticle with particle size travel 7 – 20 (nm).

The antibacterial activity of a traditional medicinal formulation also called “komi da ruwanka” used in the treatment of diseases was carried out using the agar well diffusion. The formulations sampled from three different locations exhibited a significant (P<0.05) antibacterial activity against Staphylococcus aureus: (SOK115.67 ± 0.67, SOK2 15.00 ± 0.58 and SOK315.00 ± 0.58) while there was no significant (P>0.05) antibacterial activity on the other isolates used (Bacillus subtilis, Escherichia coli, Salmonella typhi and Shigella flexnerii).

Coastal and estuarine ecosystems have been, and still are, heavily influenced by the human species through pollution and habitat loss throughout the world. This coastal pollution and its impacts have resulted in a number of environmental issues including the enrichment of enclosed waters with organic matter leading to eutrophication, pollution by chemicals such as oil, and sedimentation due to land-based activities. Over Eighty per cent of all marine pollution originates from land-based sources which are primarily industrial, agricultural and urban.

Early developmental stages of the phyllosoma larvae of three tropical spiny lobsters, Panulirus homarus, Panulirus versicolor, and Panulirus ornatus have been described by rearing them. P. homarus phyllosoma grew to the V stage in 46-61 days. P. ornatus larva reached the IV stage in 32-36 days, while P. versicolor attained the same stage in 30-38 days. More than one or two moults were recorded between different stages, such as after II stage, in all the three lobsters. Early stages of phyllosoma larvae of P. homarus could be successfully reared in low salinity of 28 psu.

The radish (Raphanus sativus) is an edible root vegetable of the Brassicaceae family.  Radishes are grown and consumed as salad, oil, medicines and as therapeutics. A particular variety of Raphanus sativus named newar or jaunpuri, grown in certain belt (Mandi Naseeb Khan) of the Jaunpur city, shows better growth in terms of length, girth and biomass. However, this was not conspicuous in nearby areas (5-6km away i.e. in Siddiquepur).

Electron microscopic studies on the adult male accessory reproductive glands of Chrysocoris purpureus insects have revealed presence of a single layer of columnar epithelium, characterized by the multi shaped endoplasmic reticulum, polymorphic golgi bodies and vesicles. The male accessory reproductive gland before mating indicates its apocrine mode of secretion and its relative quantity of secretion appears to be higher than that of the glands after mating.

This Intangible culture is the counterpart of culture, which is tangible or touchable. It includes song, music, drama, skills, crafts, and the other parts of culture that can be recorded but cannot be touched and interacted with/out a vehicle for the culture. This intangible cultural heritage is handed down from generation to generation and is constantly recreated by communities and groups in response to their environment, their interaction with nature and their history. Ritual performances also come under the preview of Intangible Cultural Heritage of India.

Development of superior and high yielding varieties made possible by accumulation of beneficial alleles from vast plant genetic resources existing worldwide. Still, a significant portion of these beneficial/ superior alleles were not used as these were left behind during evolution and domestication. Introducing novel alleles from wild crop plants to cultivated varieties have clearly demonstrated that certain alleles and their combinations potentially make dramatic changes in trait expression.

This paper presents method to detect and accurately locate circle objects in digital image. The propose method consists of two steps. In first step the edge pixels are extracted using Prewitt edge detection algorithm and then a noise removal process is run to remove the non-circle edge points. The second step, Circle Hough Transform (CHT) is applied to detect circle from the digital image.

Medicinal plants have been considered as a host of fungal endophytes with novel metabolites of pharmaceutical importance. Most endophytic fungi that live in higher plants are capable of producing secondary metabolites which are medicinally significant components whose activity against pathogens have been studied previously. Hence an effort was taken to isolate endophytic fungi from leaves of Barringtonia acutangula commonly called the Indian oak or Samudraphal, an evergreen tree with medicinal properties.
