The vegetation of the Thar Desert has great economic importance and many of them contribute to varieties of product for human use and also meet out the domestic requirement of birds. Among these, the Khejari (Prosopis cineraria), Ker (Caparis decidua), Jal (Salvadora persica) and Bordi (Zyzipus nummularia) have the vital role for biodiversity and supporting biocological activities of many birds for their survival in this region. The observations reveal that the Khejari has major important role and support a varieties of birds onthe tree and in the understory of it. These trees are used for night rest as well as for short rest during the day by birds. Caparis decedua is found to support about five species of birds. This shrub provides shelter to birds as night abode. Salvadora percica support four species of birds. Interestingly its holes of old tree trunk provide nesting to nocturnal bird i.e., spotted owlet (Althene brama). Similarly, Zyzipus nummularia support birds primarily for food and subsidiary for nesting purposes. This also provides shelter to birds from predator attack. In present work, bio-ecological observations related to food, feeding and resting behavior of various birds are discussed and are and presented in tables.

Key words: Birds, Thar Desert, Biodiversity, Predator.

The test well MNW-1 is located in the Manewala structure of Jaisalmer basin. The Cretaceous sediments are believed to contain source rocks in this basin, the samples collected from Goru formation of upper Cretaceous sedimentary sequence were investigated using Mössbauer spectroscopy to understand the relative distribution of iron bearing minerals with depth.

Iron was found present mainly in siderite, Fe2+ in clay minerals and Fe3+ in clay minerals. Large abundance of Fe3+ in clay minerals in comparison Fe2+ in clay minerals results into lower ferrous to ferric ratio in this Formation. This is an indication of poor reducing environment which is not favorable for transformation of organic matter into hydrocarbons.

Keywords: Source rocks, Mössbauer spectroscopy, Iron bearing minerals.

Over the last decennium, Visual surveillance has become an active research domain for academicians, researchers or industry due to its rapid day by day growing importance in terms of realistic environment. The solutions of the video surveillance are security tools that help us to monitor various things in terms of moving object (i.e. locations, monuments, building, people, etc. In this paper we proposed an efficient method for detection of object using background subtraction technique by enhancing the exiting method. To preserve the shape and removal of noisy pixels some post processing tools were also used. Comparative analysis of our method with considered state-of-the-art method reveals that proposed method shows better outcomes both in terms of qualitative and Quantitative analysis.

Fluoride has been reported as a health affecting substance by health organization. Fluoride in water may be beneficial and detrimental depending on their concentration and total amount ingested. The permissible limit for of fluoride is 1.0- 1.5 mg/l. Fluoride greater than limit is toxic and is associated with dental fluorosis. The flurosis is caused by oral intake of fluoride when drinking water contain more than the permitted concentration of fluoride. The amount of fluoride is increasing day by day in water samples. So, here in this research paper a comparative study has been done of the water sample containing fluoride is present in the recommended limit or not. The defluoridated is done by the mean of precipitation adsorption or ion exchange method. The comparative result is reported in the research paper.

Keywords: Fluoride, Adsorbent, Fluorosis, Defluoridation Methods.
