A simple, precise, accurate and robust RP-HPLC method has been developed for the estimation of simethicone in bulk and it’s pharmaceutical dosage form. Chromatographic separation was run through a phenomenex Luna C18 (4.6 x 250mm, 5μm) column using Water: Acetonitrile: Methanol (60:20:20v/v) as the mobile phase at a flow rate of 1.0ml/min, the UV detection was observed at 270 nm. The retention time of simethicone was found to be 4.25 min. The method produce linear responses in the concentration range of 5-30 µg/ml and correlation coefficient was found to be 0.9996.

Aquaculture over recent years has not only led to substantial socio-economic benefits such as increased nutritional levels, income, employment and foreign exchange, but has also brought vast un-utilized and under-utilized land and water resources under culture. Over the years this sector has witnessed impressive growth where culture practices have undergone considerable intensification. The Present study was carried out from 289 shrimp farmers in 32 revenue villages in 9 mandals of Nellore district.

This study is on the climatic parameters which could stimulate the rate of dryness of water from Lake Chad. It indicates that with regard to the considered parameters: duration of sunlight, temperature and relative humidity of the air, and precipitations, none has stimulated such a daily rate of dryness of 1.25 km2 of the liquid surface of Lake Chad as reported for the last fifty years.

Background: The mostly used type of waste water treatment plant in Senegal is the extensive ones. However, up today, they cannot satisfy the sanitation needs of the current population. Senegalese government, through its new developing program called “Plan Senegal Emergent”, is making tremendous effort in achieving up to 80% of sanitation access rate by 2030. Most waste water treatment plants in Senegal are activated sludge and lagoons, and treated waters are rejected in natural areas such as sea and soil, or used in agricultural activities.

The mechanism of entry of protons into erythrocyte membrane surroundings in the 8-th stage of the 9 staged closed cycle of proton conductance is needed the more detailed explanation, because cell membranes are generally impermeable to charged ions (i.e. H+, HCO3−). But should be say that during many years evolution development of organism had been formed the more appropriate way to regulate this difficulty by using the mechanism, named as exchange bicarbonate for chloride using the anion exchanger protein Band 3.

The paper deals with problem of water quality become more important than quantity in parts of Mandakini River Basin, Chitrakoot district, Uttar Pradesh. Based on the integrated studies, it has been observed that the lithology, geomorphology, lineaments, slope, effluents, sewage disposal, soil and land use/land cover was generated from Modis, Landsat ETM + data and Survey of India, (Nos.63 C/15 and 63 C/16; Figure 1.1) on 1:50,000 scale and integrated data with raster based Geographical Information System (GIS) to identify the groundwater quality of an area.

The food constituent (Barley) that is the subject of health claim is sufficiently characterized. Cause and effect relationship has been established between the consumption of barley and lowering the different perdurable health issues. The target was general population who wants to lower their health issues. A product was developed using one as standard or reference which contain only wheat flour, other three samples were fortified with barley, flaxseed, sesame seeds and coriander leaves. Among the developed product variation-2 was highly accepted.

The bio efficacy of T. viride and P. fluorescens isolates were tested in in vitro against Fusarium oxysporum f. sp. vasinfectum causing wilt of cotton. Among the T. viride isolates, Tv7 and P.fluorescens isolates, Pf5 significantly inhibited the growth of F. oxysporum f.sp. vasinfectum tested by the dual culture technique than the control. Similarly, the culture filtrate of Tv7 and Pf5 isolates were significantly inhibits the growth of F. oxysporum f.sp. vasinfectum.

The study on Indigenous Knowledge of Tribals of Pachaimalai hills, was conducted to study about adopting indigenous agricultural practices followed by tribal farmers in Pachaimalai hills in Trichy district of Tamilnadu. A sample of one hundred tribal farmers (respondents) was selected from the tribal hamlets using proportionate random sampling technique. Nearly twenty one indigenous agricultural practiceswere identified in the crops like paddy, tapioca and sorghum. In addition ten common indigenous agricultural practices were also identified.

In the present investigation, plant growth promoting bacteria such as Pseudomonas and Bacillus were isolated from the rhizosphere soil of rice (Oryza sativa L.). Bacillus is a group of gram positive, aerobic or anaerobic bacteria widely found in soil and water. Bacillus is a common free - living species found in all types of soil and environment. Pseudomonas is gram negative rod shaped and polar flagellated bacteria found in most of the environment.
