Geoelectrical sounding technique has been used to determine the groundwater potential zones in Anambra state, Nigeria. The study area is underlain by four main geological formations. A total of four hundred and fifty-two (452) vertical electrical sounding (VES) was acquired over one hundred (100) locations, employing the Schlumberger array configurations. Static water level (SWL) and yield of the aquiferous layer at various observation points were determined by pumping test fifty (50) borehole sites. The depth, thickness, lateral extent and resistivity of aquiferous horizon were determined by the electrical survey. Aquifer hydraulic properties were inferred using the empirical relationships. Interpreted VES data show predominance of A and K curve type, indicating dry overburden, underlain by wet/saturated horizon. Comparisons of geoelectric sections and borehole logs in a SW-NE direction show fairly good match, while correlation of geoelectric sections along SW-NE direction show variation in depth for the suspected aquiferous horizon. 2D maps of resistivity, depth, thickness, transverse resistance, longitudinal conductance, coefficient of anisotropy, aquifer transmissivity and hydraulic conductivity were constructed. High values of estimated aquifer transmissivity predominate, thus suggesting thick and prolific aquiferous zone. Groundwater flow direction is variable in the study area. Two potential groundwater zones were identified based on aquifer transmissivity potentials, interplay of apparent resistivity, thickness and coefficient of anisotropy. They are the moderate and high potential zones. The various contour maps and the groundwater potential zones map will serve as a useful guide for groundwater exploration and development in the study area. The developed physical transforms can be adapted to other areas with similar geologic setting.

The story of human civilization is a newer ending struggle towards a better and improved way of life. Discrimination, inequality, injustice and explanation of any kind becomes, a matter of deep concern for any civilised society. Talk of rights related to life, liberty, equality and dignity of the individual is gaining importance day by day. Human rights also have implications in the process of globalization. It is important to understand the term of human rights and to recognise it as an instrument of social justice. This paper has made an attempt to understand the concept of human rights and efforts made for the protection of human rights at international level.

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.

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
