Present paper ardently deals with the groundwater vulnerability assessment of Bagh River Watershed (WGW-1/B-designated by central ground water board) of Gondia District of Maharashtra State, India. The groundwater vulnerability assessment of the watershed is analyzed according to the guidelines provided by the APHE, ICMR, WHO and BIS10500. The parameters such as pH, EC, TDS, as well as Chloride, Nitrates, and Fluoride pre and post monsoon have been analyzed. Majority of the samples do not comply with EPA, ICMR, BIS and WHO norms for most of the water quality parameters measured. In order to protect groundwater Vulnerability of Bagh River Watershed of Gondia district, various parameters such as the industrial activities in the area, land cover/use data, hydro geological characteristics of upper aquifers, the lithology and nature of the soil zone for the area, and various predominant contaminating sources have been considered.

Water quality monitoring is fast becoming a topic of utmost importance and concern as it deals the health and health issues faced by people. One of the widely employed approaches in water quality assessment is the Nemerow index method and this approach has been employed in the current study and the groundwater quality of K.R.Puram industrial area in Bangalore, India, has been assessed. The quality evaluation has been done by collecting thirty groundwater samples each, both during the pre-monsoon and post-monsoon periods of the year 2017, in and around the K.R.Puram area and subjecting the samples to a comprehensive physico-chemical analysis. To calculate the Nemerow index, ten critical parameters vital from the health point of view has been considered, namely, pH, calcium, magnesium, total hardness, nitrate, chloride, sulphate, total dissolved solids, fluorides and iron. The NPI analysis carried out for these thirty samples revealed that a whopping 93.33 % of the samples exceeded unity, the upper limit for drinking water. The high value of NPI at these stations is mainly due to the excessive concentrations of total dissolved solids, hardness, nitrate, iron, calcium and chlorides. The analysis reveals that most of the groundwater samples are unfit for drinking purposes, which calls for continuous monitoring of groundwater supplies and to adopt a systematic environment management plan to safeguard against the pollution of drinking water.

Heavy metal (Cd, Sn, Hg and Pb) concentrations of canned fish sold on markets in Accra were determined using Atomic Absorption Spectroscopic (AAS) procedures. Levels of cadmium (Cd), tin (Sn) and lead (Pb) were determined by graphite furnace atomic absorption spectrometry (GF-AAS). Mercury (Hg) content was analysed by the cold vapour atomic absorption spectroscopic technique after Hg ions reduction with SnCl₂ (CV-AAS). The accuracy of the method was determined by use of a certified reference material (DORM-2 (Dogfish muscle).The average contents of heavy metals in canned fish brands were found as 10.03 mg/kg for tin, 0.11 mg/ kg for cadmium, 0.203 mg/kg for lead, and 0.04 mg/kg for mercury. Although these products pose no risk with respect to the concentrations of tin and mercury, some of the samples had contents of lead and cadmium higher than the acceptable limits. Comprehensive and intermittent monitoring of heavy metals in canned fish is needed to assess the safety of these products with respect to human health.

The aim of this study was to assess the biochemical and structural changes associated with exposure to gasoline vapour in rat. Twenty-four female rats were divided into test and control groups. After the exposure period, all animals were sacrificed, blood was obtained for biochemical analysis, and the liver was removed, and processed for histopathological examination. Abnormal liver architecture, liver enzymes, bilirubin, and malondialdehyde were significantly higher while serum protein were significantly lower in the exposed group than in the unexposed group (p < 0.05). Exposure to GV may represent a significant risk factor for a wide spectrum of liver disorders

The culture contains components including deeds, beliefs, arts, faiths and other social findings that are inherited through the society and form life context. These social activities are generally being formed within public and urban areas. One of these public areas is Town Square that expands cultural identity within society by users. Hierarchy also helps this study through investigation for ways of areas arrangement near each other. The main research question is how and where cultural areas of Town Square have been formed. In this study we practiced to investigate cultural identity hierarchy within Iranian Town Square to realize this question. This research aims at studying Iranian Town Square hierarchy and to extend and promote their culture. The research method applied in this study is explanatory – analytical and is a kind of field studies. Data collection method is of library and field type through observation and using schemes and figure. The study first introduced literature subject and then practiced to investigate cultural, physical and social activities within Iranian prominent Town Square including yazd, tehran, and Isfahan. In this research, cultural activities position within Town Square and their effects on social stability regarding components like cultural identity, function and framework have been investigated. Results of this paper practiced to provide effective strategies for cultural activities stability and to promote cultural identity.

High frequency unsteady peristaltic flow of a Jeffrey fluid in uniform and non-uniform tube has been investigated. The governing equations has been solved numerically and investigations are made for two cases for uniform and tapered tubes. The velocity distribution and the pressure rise is obtained. The effect of Jeffrey parameter, Womersley parameter on the flow characteristics are discussed and are analyzed through graphs for both uniform and tapered tube. Furthermore, the results obtained for the flow characteristics reveal many interesting behaviors that warrant further study of the peristaltic transport models with physiological fluids.

Ibopamine is currently used in ophthalmology. This molecule acts on both adrenergic and dopaminergic receptors. The adrenergic receptors are responsible for a marked mydriasis without accommodative paralysis, while the dopaminergic receptors promote the production of aqueous humor. That’s the reason why ibopamine may be useful for diagnostic purposes in ophthalmology. This short communication aims at presenting the most intriguing evidence on ibopamine and discusses the profile of patients who may be best suitable to this molecule.

Wiener systems identification is studied in the presence of possibly infinite-order linear dynamics and nonparametric nonlinear element. The latter can be noninvertible and of arbitrary-shape. Using simple constant and sine excitations, and getting benefit from model plurality, the problem identification problem is made. All estimators are shown to be consistent

The word guano originated from the “Quichua language” of the Inca civilization and means the droppings of bat. The bats forage at night for insect over a particular area, and they return to the old temples during the day to sleep and care for their young’s. They attach themselves to ceiling, and their excrement accumulates on e floor below. In some situation the guano can reach a depth of feet in many years and appeared as guano-hip, and it has a valuable importance. Bat guano was collected from the temple of Lonar crater Lonar, Buldana District, Maharashtra. The bat guano, it dissolved in water of Purna River, (10:100) concentration was prepared and kept undisturbed till 30 days and parameters was noted at an interval of 2 hour and thereafter 5 days for about 24 hour and 30 days respectively. Resulted into increasing in the pH content of Purna water after the addition of bat guano. Our investigation results indicate that bat guano used for bioremediation of aquatic ecosystem. 

Mathematics teachers are expected to integrate technology in their teaching to enhance pedagogical practice and student achievement. However, importance has not been placed on preparing teachers to use ICTs in their instruction. This paper reports on a study conducted to explore the feasibility of ICT use in mathematics teaching at the secondary school level. Based on an expanded variation of the Technology Acceptance Model, a survey of student teachers were collected at local universities in Kenya. It explores the factors affecting the integration of Information and Communications Technology (ICT) in instruction. A questionnaire was administered to 110 student-teachers of mathematics seeking to get their attitudes to ICT in learning and teaching and their initial experiences of the application of ICT in mathematics instruction. In-depth interviews with the student-teachers, as well as university lecturers and teachers, revealed a range of issues that reflected how student-teachers perceive integration of ICT’s in mathematics instruction. Recommendations are offered for the improvement of the ICT experiences for student-teachers during training and improved ICT infrastructure in schools. The overriding conclusion is that schools must be supported and resourced properly, and pre- service teachers must have effective ICT training.
