The present study has been undertaken to evaluate oxidative stress and urinary calcium creatinine ratio in pregnancy induced hypertension. Study was carried out in M.Y. hospital and M.G.M. medical college during 2012 to 2013. Study comprised 250 subjects 125 normal pregnant women without any complications were taken as control and 125 pregnant women with PIH were taken study cases. Normal Gynaecological examination & history based informations were taken from each subject. Fasting blood sample and morning urine samples were collected from each subject and blood samples were analyzed for free radical estimations and urine sample analyzed for calcium and creatinine. Our study shows a significant change in free radical level and siginificant fall in urine calcium creatinine ratio as compared to control study concluded that PIH can be result of increased oxidative stress. In this condition change in urinary calcium creatinine ratio indicate its relation to renal system. Study conclude that by improving oxidative stress with proper antioxidant diet or therapy we can decrease or minimize the risk associated with PIH.

The study was designed to explore the floristic composition and biological characteristics of the area. A record of plant species of Shahbaz Garhi, Mardan was organized during 2009 – 2010. A record of plant species was organized on the source of field trips conducted in winter, summer and monsoon and identified with available literature. The plants were classified into different life form and leaf size classes after standard methods. The flora consisted of 132 plant species belonging to 104 genera and 47 families. Asteraceae and Poaceae are the dominant families. The biological spectrum explains that therophytes (63 spp., 47.73%) were the dominant followed by chamaephytes (24 spp., 18.18%), magaphanerophytes (15 spp., 11.36%), hemicryptophytes (13 spp., 9.85%), nanophanerophytes (12 spp., 9.09%), geophytes (4 spp., 3.03%) and parasite (1 spp., 0.76%). Leaf size classes of plants consisted of microphylls (62 spp., 46.97%), mesophylls (28 spp., 21.21%), nanophylls (18 spp., 13.64%), leptophylls (15 spp., 11.36%) and megaphylls (9 spp., 6.82%). Analysis of the study reveals the phytoclimate to be of therophytic type. The domination of therophytes indicates that the investigated area is under deep biotic stress.

Degradation of soil is a matter of serious concern. Vast area of land all over the world has been converted into unproductive and degraded lands. Eco-restoration through plantation forests is the most effective technique to reclaim the degraded ecosystem. Six dominant species viz, Dalbergia sissoo, Pongamia pinnata, Tectona grandis, Gmelina arborea, Azadirachta indica and Cassia siamea were studied for restoration of degraded ecosystem. No amendment was given during plantations except farm yard manure (FYM), Urea and Aldrin as soil insecticide before planting the seedlings. The density of plants was 3333 ha-1. The present paper deals with the edaphic development of degraded coal mine spoil through establishment of six dominant tree species at Northern Coalfield Limited, Singrauli. The results indicated that the bulk density of the reclaimed sites was gradually reduced with the age of the plantations. The soil organic carbon, pH, EC, water holding capacity and nutritional status were found increasing with the age of the plantations. As regards the organic carbon in mine spoil under different tree cover, it was found improved to the maximum extent during 16 years interval in Dalbergia sissoo (358%) followed by Azadirachta indica (317.8%), Pongamia pinnata (273.8%), Tectona grandis (233.3%) and others. The similar increasing trend was found in pH. The electrical conductivity was the maximum in Tectona grandis followed by Azadirachta indica, Dalbergia sissoo, Gmelina arborea, Cassia siamea and Pongamia pinnata. There was gradual increase in microbial biomass from younger to older plantations in different dominant species. It ranged from 40.2 (2 years old plantation) to 51.5 mg kg-1 (18 years old plantation) in T. grandis, from 32.5 (2 years old plantation) to 66.6 mg kg-1 (18 years old plantation) in D. sissoo, from 21.2 (2 years old plantation) to 52.7 mg kg-1 (18 years old plantation) in A. indica, from 35.5 (2 years old plantation) to 50.3 mg kg-1 (19 years old plant

This study examines the reasons of FELDA settlers vote for a party and factors that influence the voting behavior of FELDA settlers in Felda Chini, Pahang. Chini (N23) is one of the FELDAs with majority Malay voters and most of the general elections in this area in the past were won by the Barisan Nasional (BN) including during the last general election in 2013. BN was also victorious in the three preceding elections in 1995, 2004 and 2008. FELDA Chini became a stronghold for BN. The study is learned upon questionnaires distributed to the FELDA settlers. Out of 507 questionnaires distributed only 348 were returned giving a return rate of 69% which is considered satisfactory. Overall, the FELDA settlers prefer to vote for the ruling party as a sense of gratitude in order to express their appreciation for the government’s contribution. The study finds that Dato’ Najib is not the leading factor for them to vote in the election.

The blood samples were analyzed for following biochemical parameters serum calcium, phosphorus, alkaline phosphatase and calcitrol. Results revealed that the significant changes observed in calcium, phosphorus and calcitriol when compared to control.

Green marketing is a new concept not only in Bangladesh but also in the whole world. Normally, it can be said that green marketing is the marketing activities operated by considering the environmental aspects. As society is going to be civilized day by day it is decaying itself by wasting its most valuable environment. Along with the others, marketing sector has also responsibility to preserve the natural resources of the world. Green marketing is the ethical marketing considering the environment which is controlled in the same way the ordinary marketing does. By implementing this new range of ideas Bangladesh as a nation is undergoing an economical reform in recent time.

Cyclic loading is common experimental practice for investigations of large structures like vehicles. Numerical analysis of cyclic loading conditions is also a well-established field of research and application. Theoretical and practical support is rare for evaluating growth of fatigue cracks under cyclic loading conditions. Cracks can occur naturally in engineered components due to combination of environmental effects and materials and geometric properties. In this study, the effects of heat treatment on crack initiation & propagation of stainless steel (SS-304) are investigated. The specimens are subjected to different cyclic load. The crack initiation & propagation and final fracture behavior are observed microscopically. The specimens are kept in the furnace at 500°C at a constant time 1 hour where cooling medium is used as air for heat treatment & the effects of heat treatment are investigated. The fatigue life of the tested specimen at 400MPa stress before & after heat treatment are 54900 cycles & 61000 cycles respectively. So, a better fatigue life is found after heat treatment.

This paper assessed the signal strength of GSM network service providers in Kwara State Polytechnic permanent site and Ara village. The latitude, longitude and elevation of the two reference locations where the study would be carry out were picked with Global Positioning System. The first location was at the gate of Kwara State Polytechnic permanent site at latitude 080 321 37.6 11 and longitude 040 381 07.711 and Ara village at latitude 080341 27.9 11 and longitude 040 381 17.311 with elevation of 350 and 364 meters respectively. The signal strength of MTN, GLO, AIRTEL and ETISALAT networks were measured with TECNO D3 Android mobile receiver from the Base Transceiver Station (BTS) at intervals of 100 meters. The measured data were analysed graphically and compared with each other to see the performance of each of the GSM network operators in the study area. The results revealed that the performance of these network providers are yet to be adjudged satisfactory.

A solar chimney power plant (also called solar updraft tower) is a solar power generating unit in which a solar air collector and central updraft tower is used to generate a solar induced air flow which drives turbines to generate electricity. This paper presents theoretical and practical experience of making a small and less expensive prototype plant which can be built on rooftops of residential buildings. The plant covering approximately 16.4 sq. meter area has a polythene cover as the collector instead of glass for reducing the cost. The base is tar covered concrete. The tower is made of PVC and approximately 3.05 meters high. Data were taken within November and December 2013. Experimental results show that the average power output varies from 3 to 20 watts and the efficiency was maximum 0.11%. The output and efficiency of the plant was relatively low because of the lacking of solar intensity as the data were taken in winter and because it was a smaller solar chimney plant. But the prototype has a low initial cost and absolutely no operating cost. Thus using of less costly components enables making of a small economical plant.

The potential of microalgae as renewable energy feedstock for biofuel production is well recognized in developing countries and it is a large source of biomass for capturing CO2 on non-arable lands. In the current studies photobioreactor with 2 L capacity was used and operated with generator exhaust gases for algal CO2 sequestration. The reactor operated on generator exhaust gases with CO2 ranges from 500-8000 ppm. As CO2 concentration increased from 500 to 4000 ppm, there were steady increase in biomass 450 mg/l of dry weight till 2000 ppm, but above 2000 ppm there is decline in growth. The fatty acid profiles were more or less constant at all the CO2 concentrations and maximum lipid content was 48%. The maximum reduction in CO2 was 70% at 500 ppm whereas it was 52% at 4000 ppm.When CO2 concentration increased to 8000 ppm without air, algae could not sustain and showed decline in biomass content. CO2 fixation from generator gases not only reduces greenhouse gases but also help in getting fatty acid as biofuel.
