The Different Type of MPPT Techniques for Photovoltaic System

We know that sun is the only sources which is available free of cost in our environment for the PV module. when the sun strikes in to the PV cell it converts to the electrical energy. Now a days to fulfill the requirement of energy the solar energy plays a main role of that. But some time this solar energy is not sufficient to fulfill this requirement than some time we use the MPPT techniques which is increase the power generation and main advantage of this techniques is that this is work in any climate. The full form of MPPT is MAXIMUM POWER POINT TRACKER. It gets the maximum power from the available PV unit and it is not depending upon the any environmental conditions. In this paper we discuss in detail the several abilities that how they get the maximum power point and system convergence, efficiency and cost of implementation. In this paper we show that all type pf MPPT techniques.

Assessment of NEWMAP Effects on Gully Erosion Control and Environmental Development over South East, Nigeria

The potential impacts of gully erosion over South Eastern Nigeria are a worrisome scenario. It has resulted in the displacement of millions of habitats, agricultural, and economic losses. The result of the effect of Nigerian Erosion Watershed Management Project (NEWMAP) monitoring and evaluation on the effect of gully erosion on economic development in this study has revealed a positive significant influence at P < 0.05 over the study region. Also, it is revealed that NEWMAP programmes have significantly covered some constructions of hydraulic structures for flood routing and soil erosion control in South East, Nigeria. This intervention has significantly reduced the rate of land degradation occasioned by soil erosion, protection of watershed and agricultural land, which has thus been responsible for improved agricultural production. In conclusion, it is imperative to conduct periodic monitoring and evaluation of the activities of NEWMAP to building a strong evidence-based mechanism that enhances assessment of the diverse range of intervention projects on the dwellers of South-East extraction.

Green Spaces Availability versus Accessibility: Case of Okhla, South Delhi

Green spaces are inevitable for people to live and grow. These spaces form an ambit for interaction with nature and people from myriad groups. This paper examines the availability of such spaces in ward no. 102S and 101S of South Delhi and the resident’s accessibility to these spaces. The green cover available per person in Sarita Vihar is 14.645 Sq m/Person which fulfils the URDPFI and WHO guidelines in contrary to 3.969 Sq m/Person for Abul fazal enclave. The Public parks are located towards the periphery in Sarita Vihar, more than the walking distance of 400m. 1 public park exists in Abul Fazal Enclave toward the extreme periphery accessible with a ticket of Rs 30 for the adults. It concludes giving possible recommendations at a micro level for better allocation of green spaces based on factors of density and context of the settlement.

Reclamation of the Enugu Coal Mine Site at Abandonment

Mining of coal (fossil fuel) resources in Enugu resulted in groundwater pollution/depletion and left the mine site with the potentials of air pollution, loss of landscape/aesthetic degradation and soil contamination. Other Environmental impacts were extensive soil damage, alteration in microbial communities and affecting vegetation leading to destruction of vast amounts of land and displacement of dwellers. Reclamation is the process to restore the ecological integrity of these disturbed mine land areas. It includes the management of all types of physical, chemical and biological disturbances of soils such as soil pH, fertility, microbial community and various soil nutrient cycles that makes the degraded land soil productive. Mining does not mean permanent loss of land for other use. On the other hand it holds potential for altered and improved use apart from restoring for agriculture, forestry and irrigation. This paper attempts to view the best practices for reclaiming the abandoned Enugu coal mine site which ceased production since 2002.

Development of Models for the Rational Design of Different Shapes of Pit Latrine

Specific models for the rational design of pit latrines of different shapes and sizes are presently non-existent. What exist are general design models irrespective of the shape and size of latrine which may not give the actual design parameters needed. This research was limited to the derivation of models that will aid the design of the capacity of pit latrines of different shapes and dimensions for different population of users and under different soil formations and ground conditions. The objective of this research was to derive models for the rational design of pit latrines of different shapes using data collected from 500 different household pit latrines already filled up. Thus, models were derived for different latrine pit shapes and sizes using data collected through the administration of designed questionnaire on 500 households having pit latrines already filled up. Models were developed specifically for different latrine shapes whereas those of other researchers were generalized. These models were calibrated and verified for the rational design of pit latrines of different shapes and sizes. The regression coefficients for calibration were 0.75, 0.65, and 0.50 and for verification are 0.97, 0.98 and 0.99 for square, circular and rectangular pits respectively. The implication of this research is availability of design models for the construction of different pit latrine shapes.

Mechanism of Corrosion in Production Wells using Stainless Steel: Review

It is essential for the designers, engineers and field operators, who designs and fabricates to be duly mindful of corrosion so as to enjoy undisturbed production, since most field materials are subjected to corrosion. This will prolong the commercial existence of production facilities. This paper provides an all-round review of challenges of corrosion while producing and proffers antidotes. The mechanism of corrosion was studied with the different kinds of corrosion that is experience in the Petroleum industry.

Physicochemical Studies, Characterization & Adsorption Capacity of Activated Carbon Derived from Dathura Stronsium Fruit Shell

In the Present investigation various activated carbon derived from waste material of plant has been synthesized .These carbon materials have high porosity .This high degree of porosity of adsorbents is associated with large surface area, which makes it an excellent adsorbent for removal of Heavy Metals. The activated carbon has advantages over the other with respect of its adsorption capacity, operating Characteristic &Cost. The activated carbon materials have been characterized by surface area, particle size, bulk density, Volatile matter, Moisture content, Ash content, FTIR &SEM studies. The goal of the present investigation was an attempt to develop low cost, highly effective and simple to use activated carbon materials for removal Cr(VI), Cd(II) and Zn(II) from contaminated water based on adsorption phenomenon. This newly developed adsorbent has been proved to be more promising for heavy metals removal without affecting the quality of treated water.
