The goal of this work is to reveal factors which control Baoulé-Est gold occurrence. Gold traps which have been extracting from structural support have been tested by a variogram with the goal to find expect mineralized axis. Rocks with good grade and geochemistry anomalies have been inserted with the goal to find mineralized axis. Mineralized axis characteristics have led to elaborate mineralization hypothesis. Gold traps are plutonic nearbourgh quartz veins and N60°, N160°, NS faults zones junctions. N30° is the like trend of gold traps.

This research explores the basics of SDI, and investigates the National SDI of different countries. Further, the research analyses SDI implementation in developing country with specific reference to the National Geospatial Data Infrastructure (NGDI) of Nigeria. The research assesses the status and the milestones of NGDI implementation using key SDI components as assessment variables. These components were grouped into four classes: Policy and Legal Issues, Technical, Funding and People.

In this age of science and Technology, mathematics now dominates almost every field of one’s activities. It has permeated through the human life in such a way that, it has now become every man’s everyday concern. Elementary education grooms students to become competent in every aspects of life. India has made a significant investment in its education. Again RTE 2009 guarantees quality mathematics education at elementary level.

RFID stands for Radio Frequency Identification. It refers to technologies that use radio waves to identify objects, animals, or people. Due to its low energy consumption and adaptability to different environments, RFID has found applications in many fields. This paper describes the basics of RFID technology, its applications, and the challenges it faces.

Energy consumption index is one of the most important criteria for judging about new, and emerging drying technologies. Electrohydrodynamic (EHD) drying is a novel method of non-thermal processing. The drying can be carried out using either AC or DC high voltages. The thermodynamic considerations regarding the lowering of temperature under EHD drying include rapid rates of evaporation and exothermic interaction of the electric field with a dielectric material. Multi-point and plate electrode systems are efficient in accelerating drying of agricultural materials.

This paper presents a review on the detailed capacitor model and it includes theoretical literature and suggestions how to measure capacitors properties at the laboratory. Theoretical part gives idea about how the capacitors work, its charging and discharging, its non-linear behaviors and capacitor types. Non-linear behaviors are presented and explained in details how to calculate them theoretically.

This work presents the steady-state performance indices of single phase induction motor, from symmetrical components of unbalanced three-phase system. The analysis of unsymmetrical fault conditions, using the method of symmetrical components, is a means of resolving an unbalanced three-phase system of impedances into three equivalent single-phase systems with independence impedance parameters.

Supplier performance evaluation and selection are multi criteria decision making problems.In supply chain, appropriate selection of vendor has become strategic problem. The decision of supplier selection is unstructured and complicated task purchasing managers of any company. Supplier evaluation process consists both quantitative and quantitative criteria.

Spectroscopic analysis was used to study the effect of the interaction of egg albumin with amantadine in SPAN-40 solution. Protein binding properties of Egg albumin-amantadine complex were investigated by fluorescence spectroscopic technique. From the fluorescence spectral data stern-volmer quenching constant and the quenching rate constant have been calculated and reported. Other constants calculated for the surfactant SPAN 40 micelle were aggregation number, radius, surface area per head group and packing parameter.

Value is a word that is used in many aspects of the world. Understanding the concept of value helps guide the professional in their daily practice as they perform their daily functions. The review of value as a concept is based on an understanding of what value is through how it is used and its defining attributes. To strengthen this understanding, a model case and a contrary case are provided to guide an application of the concept of value in different settings. To support this, antecedents, consequences, and empirical referents are discussed.
