Abstract: The mineral deposit of Kizhnica belongs to "Hajvali-Badovc-Kizhnica" ore field, and extends in the central part of it`s together with Badovc mine. Lead (Pb), zinc (Zn), and silver (Ag) are the major metals of economic priority for which the industrial ore reserves have been calculated in this paper presented the distribution of major metals (Pb, Zn, and Ag), and with special emphasis, we studied the main geochemical association of lead (Pb) and zinc (Zn) sulfides mineralization of the Kizhnica deposit. According to the factorial analysis, the result of these geochemical associations is as follows: Zn-Ag-As; Cd-Cu; and Pb-Sb. In 1% of the content of lead (Pb) has 10g/t silver (Ag). Variation coefficient for lead is VC^Pb = 85.67% and for zinc is VC^Zn = 103.95%. 

Abstract: Diesel engine is a popular prime mover in rural areas, particularly in the places where electrical power is not available. The rapid depletion of fossil fuel with increased environmental concern has stimulated worldwide efforts to produce alternative to diesel. The fuel of bio-origin may be the biodiesel obtained from edible or non-edible vegetable oil through transesterification process. Most of the properties of biodiesel compare favorably with the characteristics required for CI fuel. This fuel in the form of blend with diesel performs almost as neat diesel fuel with no engine modification. Honge oil is non-edible vegetable oil and coconut is edible oil.  In the present investigation the blends of proportion B20 is made for Honge (Pongamia) Oil Methyl Ester (POME) and coconut Oil Methyl Ester (COME) with diesel were used to run a single cylinder CI engine and significant improvements in engine performance was noticed for combined blends of POME and COME. This project presents the performance analysis of CI engines using pongamia, coconut oil and their combined blends with diesel. 

Abstract: The environmental factors of coastal areas are very important, because the variations in the Physico-chemical properties, such as temperature, salinity, pH, dissolved oxygen and nutrients will impact the life span of the fauna and flora in the sea. It regulates the species richness in the coastal area. If the Physico-chemical parameters are not suitable, it will affect the distribution and the life style of the Biota. The  variations in the  nutrients load along the coastal waters is due to the  natural weathering, riverine, land and anthropogenic input .However, the  natural seasonal changes keep the coastal waters well mixed and aerated, which help to scatter the nutrients useful for the Biota. In the present study the environmental parameters such as temperature, DO, salinity, pH, Nutrients and Chlorophyll-a were recorded from January 2014 to December 2014. The data suggests that during the monsoon period, a significant increase of fresh water and land side input into the coastal area and have elevated nutrient concentration compared with other seasons. The qualitative study showed the present status of the Physico-chemical parameters, which is very useful to evaluate the health of the coastal system and also to take precautionary measures to save the coastal environment. 

Abstract: The district is irregular hexagon in shape in the northeastern part of the State lies between 2702” east longitudes. It is surrounded by Churu district on the northwestern side Hissar and Mahendragarh district of Haryana State in the northeastern part and by Sikar district in the west, south and south eastern part-2. For the propose of administration the district is divided into five administrative subdivision viz, Chirawa, Udaipurwati, Jhunjhunu, Khetri and Nawalgarh Six Tehsil viz Jhunjhunu, Chirawa, Khetri, Nawalgarh, Buhana, Udaipurwati and eight Panchyat Samities viz Jhunjhunu, Chirawa, Khetri, Nawalgarh, Buhana, Udaipurwati, Alsisar and Surajgarh.

Abstract: Efficient working capital management is pivotal to the operational and financial health of industrial enterprises, especially in developing economies like India. In Rajasthan, industrial areas are characterized by diverse sectors where small-scale industries play a crucial role. This paper examines the efficiency of working capital management across Rajasthan’s industrial areas, highlighting sectoral variations, structural challenges, and performance outcomes. Using secondary data from government reports, census data, and financial abstracts, the study finds that while industrial sectors invest heavily in current assets, inefficiencies persist in asset turnover, inventory management, and liquidity positions. Recommendations are offered for policy and managerial interventions to enhance working capital efficiency, fostering sustainable industrial growth in Rajasthan.

Abstract: The Shekhawati region, part of semi-arid Rajasthan, exhibits significant botanical diversity, especially concerning ethnomedicinal plant species relied upon by local communities for healthcare. This paper assesses the conservation status, patterns of species distribution, and critical threats facing medicinal plant diversity in Shekhawati before 2014. Comprehensive surveys and secondary literature analysis indicate that habitat loss, overharvesting, lack of awareness, and inadequate policy enforcement have led to the depletion of rare and commercially valuable species. Emphasis is placed on the urgent need for in-situ and ex-situ conservation strategies, along with community-driven conservation models, to safeguard traditional knowledge and biodiversity for future generations.
