The research aimed at evaluating the potentials of consortium of banana, orange and potato peels as bio-sorbents in the purification of paint industrial wastewater, using column adsorption technique. The experimental conditions observed were pH 4 and 8 and adsorbent doses 1 g and 2 g. Atomic Adsorption Spectrophotometric method was adopted to evaluate the physicochemical properties of the wastewater samples. Results showed that the consortium were effective in the removal of COD, BOD, total solid, colour, turbidity, nitrate, chloride, copper and cadmium while the values of lead, sulphate and phosphate was observed a noticeable increase on the treated wastewater samples. The best experimental conditions according to the adsorption capacity were pH 4 and 1g adsorbent dose. The efficacy of the percentage removal for heavy metal and inorganic anions in the wastewater samples after treatment were in this order: Cl- ? Cd? NO3– ? Cu. It can be deduced that all models can be used reasonably well to describe the behaviour of the adsorption of cadmium, copper, chloride and nitrate. The best model for the column adsorption process was observed to be Yoon – Nelson isotherm model which have the highest correlation coefficient values of the study. The results of this study showed that the agrowastes consortium has the potentials in the treatment of industrial wastewater, which is cost effective, economical and eco-friendly. 

The phytoremediation capability of Eleusine indica on Copper and Nickel contaminated soil samples was investigated using standard techniques. Soil sample and seeds of E. inidca were collected from a farmland in Obe, Nkanu West L.G.A of Enugu State. 0%, 1%, 2% and 3% potted treatments of Copper and Nickel contaminated soil were made for three samples (initial sample, sample without plant and sample with plant). The plant samples were subjected to Bioaccumulation factor and Translocation factor examination while the Soil collected from these samples were subjected to soil analysis tests (Metal determination, pH, Soil moisture content, total organic carbon, and cation exchange capacity). The results from the study revealed Eleusine indica as a phytoremediator having BAF>1 for Cu (0% = 1.25, 1% = 1.35, 2% = 1.31 and 3% = 1.36) and Ni (0% = 1.31, 1% = 1.53, 2% = 1.80 and 3% = 2.06) contaminated soil samples. The translocation factor (TF) were also observed to be greater than 1 (TF>1) in all the treatments for both Cu and Ni contaminated soil. Heavy metal contamination of soil reduces its total organic carbon and increases its cation exchange capacity. Eleusine indica is a hyperaccumulator, its root stores more heavy metals and thus suitable for phytoremediation.

The present study is aimed to analyze the statistical relationship among various water quality parameters and water quality index (WQI). For this, observed results of physico-chemical analysis of 71 ground water samples of study area in pre- and post-monsoon season and calculated water quality index values for each respective sample were taken into consideration. Correlation coefficient between every water quality parameter and WQI values is calculated and for the pairs having highly significant correlation coefficient (0.8<r<1.0) values; regression model is applied and scatter plots are drawn. The systematic correlation and regression study suggested the perfect linear relationship between Fluoride and WQI Values. The analysis provides essential information regarding the dependency of water quality rating on each water quality parameter.

This article presents the Marital Psycho-Spiritual Intervention (MP-SI), which provides the married couples and helping professionals with knowledge and skills for strengthening marriage relationships. MP-SI is an intervention that specifically developed to help Muslim married couples build a close relationship with Allah SWT, with themselves, and with their respective couples. This intervention is a structured format. In each session, the participants are exposed to the knowledge of Islamic marriage. The content of this intervention takes into account the content of the Holy Quran on man’s creation, which consisted of four important elements, nafs (soul), aql (intellect), qalb (heart), and ruh (spirit). The participants are exposed to effective communication skills, worked as teams to resolve problems, managed conflicts without decreasing closeness, preserved, and enhanced attachment through communication elements, conflict resolutions, forgiveness, sakinah (tranquility), mawaddah (love with passion), and rahmah (mercy). This intervention may be applied in counseling and coaching interventions, as well as relationship education, couples’ workshops and retreats.

This paper describes the sexual violence in John Grisham’s novel A Time to Kill. The Sexual Violence in America is because of racial Discrimination, and in India is Rich and Poor. Money makes many thing in Indian constitution.

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 traditional physical education teaching mode limits the main demands of students and cannot meet the requirements of the society for physical education. Flipped classroom teaching mode, as a new teaching mode, has its advantages fully reflected. In this paper, the advantages and disadvantages of flipped classroom teaching mode and traditional teaching mode are compared by means of literature data method and logical analysis, and the specific steps and principles for attention are integrated into physical education teaching, hoping to improve the level of physical education.
