Abstract: Geopolymer concrete is the concrete made without using any quantity of cement. Instead the waste material from the thermal power station called Fly Ash is used as the binding material. This fly ash reacts with alkaline solution like Sodium Hydroxide (NaOH) and Sodium Silicate (Na2SiO3) and forms a gel which binds the fine and coarse aggregates. Similarly another Artificial material called Manufactured Sand (M-Sand) is also used as the fine aggregate against the normal river sand. Concrete cubes of size 100 ? 100 ? 100 mm, Cylinder specimen of size 150 mm diameter and 300 mm height and Prism specimen of size 100 ? 100 ? 400 mm were prepared for both the Geopolymer Concrete with M-sand and conventional ordinary Portland cement concrete, for the same mix. The Cube compressive strength, Split Tensile Strength, Cylinder Compression and Prism Beam Flexure Tests were found out at 7,14, 21 and 28 days. The strength of Geopolymer Concrete is compared with normal cement concrete and found the strength of Geopolymer concrete with M-sand is high. Hence, pollution free Geopolymer concrete with M-sand can be an alternative to ordinary Portland cement concrete.

Abstract: Groundwater is the major source for drinking and irrigation purposes in Vattamalaikarai River basin, Tamilnadu, India. Though the basin area is very small, the groundwater quality variation is highly erratic. Thus a field study was conducted during November 2011 for the rapid assessment of suitability of groundwater for drinking and irrigation purposes. Some of the important insitu groundwater qualilty parameters such as temperature, pH, electrical conductivity and salinity were measured in 70 observation wells. Based on these parameters, areas which are suitable for drinking and irrigation were demarcated using geographical information system (GIS). The study indicates that about 60% of the Vattamalaikarai River basin area is suitable for drinking purposes. Groundwater quality is not good in the western part when compared with eastern part.

Abstract: Root zone Treatment Systems (RZTS) use natural processes to effectively treat domestic & industrial effluents. The process incorporates the self regulating dynamics of an artificial designed soil ecosystem. RZTS are by now well known in temperature climates and are easy to operate onsite treatment facilities, which involve less installation, maintenence and operational costs than the conventional treatment methods. Also RZTS offer cost effective options for decentralization of wastewater treatment. In the present experiment, root zone plant system with additional seperation and adsorption unit have been worked to reduce waste water quality parameters (pH, turbidity, Biochemical and Chemical oxygen demands, total Solid etc) effectively.

Abstract: In this research work, the effect of brackish water in the strength properties of concrete was investigated. The results of experimental investigation in strength of concrete with partial replacement of cement when prepared with treated water and with ground water are presented in this paper. The concrete grade of M30 has been selected and designed as per Indian Standard method. The specimens based on control mix have been cast without fly ash and silica fume. Cement was replaced by 0%, 10%, 20%, 30%, 40%,50% and 60% of fly ash by the weight . 20% of silica fume was added to all those mixes and further replacement of cement was tried. Necessary tests were carried out and results were compared for both concrete prepared using treated water and using brackish water. Workability was found from slump test. Tests for compressive strength were carried out on specimens at the age of 3,7,14 and 28 days. The split tensile strength and bond strength test were also carried out at the age of 28 days. The results showed that the compressive strength of concrete for control mix prepared using treated water is 45.6 N/mm2 and using groundwater is 31.96 N/mm2. The property indices of both fresh and hardned concrete have higher values in the specimens prepared using treated water than in the specimens prepared using groundwater. From this study it was concluded that 10% replacement of cement by fly ash contribute reasonable strength along with 20% of the silica fume when groundwater was used to prepare concrete. The presence of chemical parameters in brackish water influences the strength of concrete was presented in this paper.

Abstract: Biofuel is becoming prominent among the alternatives to conventional petro-diesel due to economic, environmental and social factors. In this paper we have presented a study of the quality of biodiesel influenced by the physical and chemical properties. The values of physical and chemical properties of biodiesel were compared with American Standards and Testing Materials (ASTM). The physico-chemical properties of groundnut oil and reused groundnut oil were assessed for their potential in biodiesel production. We determined acid value, saponification number, Iodine value, cloud point, pour point, kinetic viscosity, flash point, fire point, copper strip corrosion, cetane number, heat of combustion, specific gravity and boiling point. The results show that the groundnut oil produced high qualilty biodiesel as compared to reused groundnut oil.

Abstract: Detailed texture and organic carbon percentage of the sediments of Thengapattinam estuary covering the entire biotope from the marine to the riverine zone are presented. This estuarine system in Tamil Nadu is found to be a zone of pollution caused by sewage entering the estuary through AVM canal, inflow of water from paddy fields and coconut plantations and also the retting of coconut husk. Seasonal variations of organic carbon content in the sediments were studied in relation to textural pattern. The present study reveals that textural pattern determines the selective enrichment of organic carbon. The sediments are mainly sandy loam, loamy sand, sandy clay loam sand and sand. In monsoon season the sediment was mainly sandy clay loam with higher levels of clay and in the post monsoon and pre monsoon seasons the sediment was found to be sandy loam and loamy sand except in the mouth of estuary. The organic carbon content varied from 0% to 1.326%. Low level of sediment organic carbon was noticed in monsoon season. Correlation between texture and organic carbon reveals that fine grained sediments like sandy loam, loamy sand and sandy clay loam have higher OC content than sand. Hence sediments in the estuarine region have relatively higher OC content than the mouth of the estuary and the riverine system.

Abstract: In this study an attempt has been made to assess the production of TMA-N in the Sciaenid fishes Johnius belangerii and Nibea Maculata during cold storage. The impact of storing the fish with gut and after degutting on the production of TMA-N were studied to evaluate the effectiveness of TMA-N as an index for estimating the freshness of fish. The acceptability of the fishes sold in the local market was investigated in relation to the level of TMA-N in the fishes collected from the landing centre. Fishes collected from the landing centre were grouped as Gutted and Without Gut and stored in refrigeration at -4? C. The amount of TMA-N produced in the stored fish in increasing days of storage was determined bio-chemically. The increase of TMA-N was proportionately less in the early hours of storage and significantly increase in the final hours of storage during this study. The TMA-N content of fish stored after degutting was lower than the fish stored with gut. Significant propogation of the market samples had TMA-N content above the standard maximum acceptable limit. The present study documents the effectiveness of Trimethylamine-nitrogen in the estimation of the freshness of fish. This study further indicates that the current methods of fish harvesting, transporting, storage and retailing lack sufficient refrigeration.

Abstract: Effluent from pulp and paper industry contains various heavy metals such as Cu, Zn, Pb and Ni and also rich in organic material such as lignin. This offers two possibilities Firstly. It is a waste material which is highly toxic and secondly its toxic impact could be minimized. That can offer huge organic material and valuable nutrient at disposal. Keeping this in view, the effluent was characterized on various physico-chemical parameters and current status has been revealed in this paper. Few pot experiments have been conducted with paddy crop, i.e. at different dilution in order to assess the agro potentiality. It has been revealed that at diluted concentration at about ten percent there was an increase in root length (9%) , shoot length, (14%) germination percentage (3%) as well as seedling dry weight (6%). This reflects the utility of effluent in diluted concentrations specially at ten percent.

Abstract: Environmental degradation is one of the prime indictors of unsustainable socio-economic and inequitable development. The urgent need for present times is to utilize our natural resources in a sustainable manner so that their depletion is minimised and pollution is kept under control. As the global population continues to increase rapidly, the growing human need for freshwater is leading to a crisis like situation in many parts of the world. The fresh water resources comprise the river systems, groundwater and wetlands. Updated information on environmental changes undergoing in these life support fresh water systems, the State of Jammu and Kashmir is bestowed with a number of lakes and wetlands which have been notified as Ramasar Sites. Mansar and Surinsar are two such lakes located in Jammu region. These lakes for their importance to local communities and tourism are being monitored by the State Pollution Control Board for their water quality. The paper highlights the Physico-chemical characteristics of Mansar and Surinsar lakes based on the parameters recorded during the year 2010-2011. Chemical analysis of lake water sample reveals that the Ca and Mg account for 68% of the cations and HCO3 accounts for 85% of the total anion. The concentration of phosphate (<0.01) confirms that the lakes have entered into eutrophic stage. High values of alkalinity and hardness and their direct relation with each other show that they are resulting from a common source of dissolution of carbonates.

Abstract: Signatures of the Earth ' s crustal tides are recorded in the groundwater regime, particularly in confined aquifers in the form of rise and fall of its piezometric heads with high frequency digital water level recorder. The impact of Earth tide on groundwater is clearly recorded at two sites namely, Kothagudem (Khammam district) and Mangapet (Warangal district). The wells at these sites are constructed in the confined aquifer of Kamthi sandstone in Godavari valley which nearly 200km inland from the east coast. Analysis of the data reveals that the piezometric level heads fluctuate in a cyclic manner and the variations for each lunar cycle of 13-14 days with high peaks on new Moon and full Moon days. The peaks observed in the piezometric heads gradually decline coinciding with the lunar phase. Distinct changes in piezometric heads observed for each phase of the Moon in both of the above-mentioned places. An account of impact of lunar and solar attraction forces on piezometric level heads of groundewater, the ideal conditions required for recording this phenomenon along with comparison of these hydrographs with examples from the literature are provided in the present study.

Keywords: Dimensional analysis, model efficiency, soil water content, subsurface drip irrigation.
Abstract: A model was developed using dimensional analysis approach for determining geometry of wetted soil zone under point sources of water application with subsurface drip irrigation(SDI). The predicted values of wetted depth and width were compared those obtained through field experiments conducted in black versitols at the Central Institute of Agricultural Engineering, Bhopal, India. Experimentation included determination of maximum depths and widths of wetted soil zone after 0.5, 1, 2,3 and 5 h of water application through SDI laterals placed at 0.05, 0.10, 0.15, 0.20 and 0.25m depths below the soil surface. The effect of discharge, depths of placement of laterals and duration of water application on wetted width and depth were observed. Statistical analysis revealed no significant difference between predicted and observed values of wetted width and depth. Predictability of model expressed in terms of model efficiency was found to be 88.7% and 93.3% for wetted width and depth respectively. Therefore, the developed model could be used to simulate wetted depth and width under SDI with point source of water application.

Abstract: Impact assessment of climate change on potato productivity in Punjab for three potato cultivars of late (Kufri Badshah), medium (Kufri Jyoti) and early (Kufri Phukraj) maturity groups was carried out for A1FI scenario of temperature and atmospheric CO2 of the years 2020 and 2055. The simulation study was done using WOFOST crop growth model for potential production at 13 locations in Punjab. The results from the simulation study were interpolated using kriging technique to generate maps of potential productivity and the changes thereon. It was estimated that rise in temperature alone will result in change in productivity of Kufri Badshah from +11.6% (Amritsar) to -10% (Fatehgarh) in 2020, whereas the change in productivity of Kufri Jyoti will be from +11.6% (Amritsar) to -11.6%(Fatehgarh) and of Kufri Pukraj from +12%(Amritsar) to -11.5%(Mansa). During this period, CO2 fertilization is expected to increase tuber productivity from +3.9% to 4.5%, depending upon cultivar and location. However, in 2055, a mean decrease of 17.9 (Kufri Badshah), 21.1 (Kufri Jyoti) and 22% (Kufri Phukraj) is likely in the productivity due to rise in temperature only, while the expected rise in CO2 is likely to bring about 17.3(Khufri Badshah) to 18.5% (Kufri Jyoti) increase in potato productivity of potato cultivars will not be affected in 2020 over the baseline scenario, but will decline in 2055 (Kufri Badshah, -2.62%; Kufri Jyoti, -4.6% and Kufri Pukhraj, -5.3%), when the total geographical area of Punjab is considered. It is further shown that if the present distribution of potato acreage within Punjab remains unaltered in future, there will be benefits from climate change as the potential productivity of Kufri Badshah, Kufri Jyoti and Kufri Pukhraj will increase by 3.3%, 3.1%; and 3.6% in 2020, although the potential productivity will again decline to baseline values in 2055 (+0.1%, 1.5% and 1.9% respectively).

Abstract: Genotoxic and mutagenic potential of chrysotile asbestos on animals and humans has been extensively documented, but limited information is available regarding its effects on plants. In the present study, Allium cepa L. bulbs were exposed to four concentrations (0.5,1.0,2.0 and 5.0 g/ml) of chrysotile asbestos under laboratory conditions and alterations in certain cytogenic parameters were studied at 24h intervals till 96h.
In control plants a time and concentration-dependent decrease in the number of cells in prophase was found, but in exposed plants progression of prophase stage was found to be slow. In control plants, the number of cells in metaphase was found to decrease with time, but in exposed plants a gradual decrease was recorded. A time and concentration-dependent decrease in mitotic index was found in exposed plants compared to respective controls. An increase in the number of interphase nuclei, spindle disturbances, chromosome stickiness and micronuclei formation was also recorded in exposed plants. The present findings report genotoxicity of chrysotile asbestos in plants.
