Abstract: Natural, modified and synthesized minerals have been extensively employed for the removal of heavy metals and hazardous Ions from water and wastewater. As one of the most widely distributed earth materials, natural zeolite has been subjected to many studies for its removal of heavy metals from water. Zeolite minerals can be effectively employed for the treatment of metal-contaminated wastewater streams and aqueous solutions due to their wide availability, low-cost and high effectiveness advantages. This work reviews the existing knowledge and research on the removal of heavy minerals by different types of natural and modified zeolite. We compiled and critically reviewed more than 100 scientific articles and papers. This review article focuses on the examination of different parameters affecting the removal process and their individual impact on adsorption and ion exchange as the main mechanisms of the process. 

Abstract: Increased interest rate volatility in the 1970s and 1980s has led to greater volatility in the returns on bonds and other fixed income assets. Consequently, investors in bonds and financial institutions with fixed income assets are now exposed to much greater risk from capital gains and losses. The problem is compounded because managing risks caused by interest rate risks caused by interest rate volatility has traditionally been difficult and costly. 

Abstract: In this study, we applied a probabilistic methodology to seismic hazard assessment in the lake Tanganyika Rift and accounting the local geological condition. We had proposed to create a phantom stations across the affected region with spacing each grid point 1° x 1° kept constant at 0,1° by 0,1° and computing return periods of ground motion exceedances to obtaining a very small value of Maximum distance, like 4 to 94 km, to get a report of this probability. We had obtained 0,01520016 km/s² and 2,04414004 km/s² respectively for an epicentral distance of 4 km and 94 km. The return period of 3028 years (4km) and 27 year (94 km) corresponding at the annual probability exceedance of 0,03% and 3,73% respectively. Accounting for local geologies conditions the average value of PGA in the lake Tanganyika region  is less than 1,6 however, this region is mainly dominated by the soft rock/hard rock ratio. 

Abstract: An experiment was conducted to examine the effect of replacing maize with mango seed kernel meal (MSKM) in the diets of Weaner rabbit on performance, carcass characteristics and economic of production. Twenty mongrel rabbits were randomly allocated to four diets in which mango seed kernel meal replaced maize at 0, 33.33, 66.67 and 100% level designed as diets 1, 2, 3 and 4 respectively. The daily feed intake (42.75-49.76), daily weight gain (8.75-9.72) and feed conversion ratio (4.64-5.19) obtained were not significantly (P<0.05) affected by the dietary levels of mango seed kernel meal. Carcass yield and weight of organs expressed as percentage of live weight did not significantly differ between the treatment means. The cost in naira per kilogram gain was highest on diet 1 (0%MSKM) and lowest on diet 4 (100% MSKM) having N338.84 and 245.58 respectively. The result indicates that mango seed kernel meal can replace maize at 100% level in the diet of Weaner rabbit with better performance and tremendous reduction in feed cost. 

Abstract: The broad bean weevil Bruchus rufimanus, its development cycle involves an annual generation (monovoltin). Its life cycle dependes strictly on its host plant. The objective of this study is to know in successive steps, the conditions of the colonization of the broad bean crops by this bioagressor in the area of  Haizer (Bouira), in order to provide the key to better combat this pest adapted to the conditions of our agricultural systems. The colonization of the two broad bean plots by this beetle coincides with the full flowering. The egg-laying period ranged from 28 days for Seville variety, and 35 days for Faba bean variety. It varies depending on weather conditions. Oviposition occurs on all pods whatever their stage of growth. Larval development takes place during the ripening pods. It is carried out in four larval stages L1, L2, L3 and L4 and pupae. The complete development cycle of the weevil from egg laying until the emergence of the first adult takes about 4 months and 16 days for parcel Seville variety and 4 months and 18 days for the parcel variety Field bean variety. 

Abstract: This paper proposes a combined automatic wind-electric system for efficient use of water in agriculture which is supported by self generated power by windmill. India seems to be significantly behind in terms of automation and sophistication in agriculture. We are not able to cultivate faster and maximize our yields through automation. We therefore thought of applying the field of electronics to our main occupation i.e. agriculture. Efficient irrigation is the process of developing a technique which supplies precise amount of water directly to the root zone of the plant, offering adequate irrigation and sufficient quantity of water. It discourages the growth of weeds and helps to prevent from fungal diseases which often grow in moist environment. Since today, world water resources are diminishing at a higher rate, therefore we have involved “Drip Irrigation System” .This saves water and delivers water using mainlines and sub-mains with emission points along their lengths. Each dripper/emitter, orifice supplies a precisely controlled uniform application of water by the plants in proper amount. Thus, this system ensures that plants never suffer from water stress, enhancing quality, its ability to achieve optimum growth and high yields. The main components of the model developed here are soil moistures sensor, microcontroller, water pumping system and windmill. The combination of automatic drip irrigation system which is operated with windmill energy is making this work unique. World energy demands are increasing continuously due to increasing of the world population, economic growth and energy usage .The combination of a wind –electric system with suitable irrigation equipment for watering crop fields could also make the supply of electricity for common applications in regions without a public electric grid. 

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.
