T.J.K. Ideriah, S.A Abere and W.Trinya

Abstract

The contributions of VOC, CH4 and TSP to the concentrations of Total Hydrocarbon in plant leaves along selected roadsides in Port Harcourt were investigated. Air and plant samples were collected from roads during the dry and rainy seasons. Hydrocarbon content in plants leaves was determined using a 21D spectrophotometer while gaseous air pollutants were determined using portable hand held air monitors which include an Industrial Scientific Corporation ITX Multi Gas Monitor and Aerosol Mass Monitor by Met One Instrument INC. The results showed highest concentrations of TSP (0.946 mg/m3), VOC (4.2ppm), CH(5.0ppm) and HC (8,844.71mg/kg) in the dry season and TSP (0.129 mg/m3), VOC (1.2ppm), CH4 (1.5ppm) and HC (58,220.0mg/kg) in the rainy season. The concentrations of VOC recorded at the study stations exceeded permissible limit recommended by the Federal Ministry of Environment and therefore call for serious environmental concern. The mean concentrations of hydrocarbons in plants leaves and the gaseous pollutants measured during the dry season were generally higher than the mean concentrations measured during the rainy season. The differences between the dry and rainy season values were significantly different at P≥0.05. The levels of gaseous pollutants and hydrocarbons in plants leaves are influenced by seasonal variations. The correlation between TSP in air and THC in leaves (TSP/THC) showed higher coefficient (0.5192) in dry season than (0.2687) in the rainy season while VOC/THC was higher in the rainy season (0.1623) than in the dry season (-0.1340) and CH4/THC (0.0607) in the rainy season and (0.0601) in the dry season. The trend of the squar d correlation coefficients was TSP/THC > VOC/THC > CH4/THC in both seasons. The volatile organic carbon in the air is not the major contributor of total hydrocarbon in plants leaves in the study area.

Abstract

In view of the significant importance of wetlands in the ecosystem and regional economy of wetland birds, an attempt has been made to analyze the physico-chemical characters of wetland waters in Mainpuri district. Physiochemical studies of wetlands of Mainpuri was conducted six times in an year, during April 2011 to Feb 2012 to estimate the water pollution status of wetlands at Mainpuri .The work has been taken up as a comparative study of the five study sites viz- Site-I(Markandeshwar), Site-II (Bhamwat Canal), Site-III (Saman ), Site IV(Sauj) and Site-V(Kirithua). In this paper we discuss temperature, pH, DO, BOD, COD, TDS, TSS and Hardness of water from these wetlands. The results indicate that the water is hard .These wetlands at Mainpuri requires attention and concern for their conservation. They support the rich fauna found there including habitat for many local and migratory birds. Saman and Sauj(Site-III and IV) are IBAs(Important bird areas) under Important Bird Areas Programmes of BNHS and Bird Life International. 


Time Domain Reflectometry (TDR) based Technique for Detection of Blood Group

Jinan F. Mahdi, S. N. Helambe and Nazneen Akhter

Abstract

Time Domain Reflectometer (TDR) based techniques are known to be very useful for studying dielectric properties of liquids over a wide range of frequencies. Dielectric properties of liquids cover a vast area of interest for scientists from a variety of disciplines of science and technology including medical physics and bio sciences. Human Blood consist of complex biological molecule and exhibit different characteristics based on the constituents and their relative proportion. We present TDR technique for determination of human blood group. This method of determination of blood relies on dielectric properties of blood and makes use of the lag time introduced by blood sample in the reflected waveform. The approach works well and can be further refinements by designing  different sample cells with impedance matching and improved waveform analysis techniques using sophisticated instrumentation for higher time resolution. The blood group of the sample is found from the reflected waveform from the TDR setup by measuring the lag time introduced. The system is tested for its reproducibility and accuracy by conducting series of experiments. The resulting waveforms are analyzed manually and using computer program, from graphs using the TDR data file. There is excellent agreement between blood group determination using this technique and the conventional pathological laboratory methods. The relation between the lag time and the blood group of the sample is presented and details discussed.

Abstract

Natural preservation of a settlement is very important for a sustainable life. Especially when the livelihood of inhabitants in the  settlement depends on the surrounding natural resources. As happened in kampung wonorejo, some of the inhabitants work as fishermen, fishpond farmers, and catfish farmers. Kampung is a typical dense urban settlement and inhabited by the lower middle income people, formed without planning and the infrastructures tend to inadequate. The aim of this research was to examine the state of the settlement and the importance of preservation in relation to life support in coastal village. The method used was explorative survey and observation to find the actual field condition. The result showed that the inhabitants of kampung wonorejo have utilized the nature as well as did natural preservation. With the potential of existing natural and awareness of the community to improve their quality of life, kampung wonorejo will be a livable kampung.

The Unconventional Sources of Oil and Gas: The Fuels for Growth in the 21st Century

Sumeer Kalra and Shantanu Asthana

Abstract

The energy scenario today is quite challenging. The demand for energy is increasing day by day. As the world progresses in the 21st century, with more and more people rising above poverty throughout the world, the global energy demand has increased exponentially in the past few decades. The cause of concern is that this demand cannot be met by the depleting conventional  reserves, particularly oil and gas. A partial solution to this problem is the unconventional sources of hydrocarbons i.e. Shale, Tight Gas Sands, CBM and Gas Hydrates. Tertiary development through EOR in conventional reserves is very costly. Instead of spending huge sums of money on fields which are in their last stages, we can look to utilize some of that into exploring the unconventional sources of Hydrocarbons. In this paper, we first try to compare the aspects of exploring new unconventional sources against the improving the present conventional reserves. (Example: Schlumberger has pegged the reserves of gas in shale deposits across the country at 300 times higher than Reliance’s Krishna Godavari (D6) basin, by far the largest gas field in the country while the ageing fields are supposed to pull down ONGC's output by 3% in Financial Year 2012). Then we do a detailed analysis of the unconventional sources of Oil and Gas (Shale, CBM, Tight Gas Sands and Gas Hydrates) through 5 strategic management methods (SWOT, BCG MATRIX, 5 Force Model, Involved Threats, Space). On the basis of these analyses, we will derive appropriate conclusions.

Abstract

Fungi were isolated from the soil sample and it was characterized as Aspergillus sp by Lactophenol cotton blue staining. The  antimicrobial activity of fungal extract was tested against pathogenic bacteria and fungi. The extract was tested against eight bacteria and five fungi. Then bioactive compounds were purified by silica gel column chromatography and it was identified by Gas Chromatography-Mass Spectrometry. Eight compounds such as Benzene, 1-fluoro- 4-meth; 3-Benzyl sulfanyl-3-fluor; 1H- ndene,1,3-dimethyl-; 1H-Indole,1,2- dimethyl-; 3Beta-acetoxy-4,4,8,10,1; Benzene,1-fluoro-3-methyl-; 1H-Indole,1,2- dimethyl-; 1,2- denzenedicarboxylic acid were identified. Cytotoxic activity of fungal extract on HepG2 were analysed by Trypan Blue dye exclusion method.Random amplified polymorphic DNA (RAPD) analysis was performed on Aspergillus sp isolated from soil sample. Nine primers such as OPA 01, OPA 02, OPA 03, OPA 04, OPA 05, OPA 06, OPA 07, OPA 08, OPA 09 were used for the RAPD analysis. DNA banding patterns generated by RAPD were scored for the presence (1) or for absence (0) of each amplified band. For genetic distance analysis, using NTSYS software Cluster analysis was based on similarity matrices using the unweighted pair group method analysis (UPGMA) program in the software package.
