The aqueous extract of Pomegranate Peel and Roselle (AE Pom P and Ros) has been studied as a possible source of green inhibitor for the corrosion of mild steel in 1 M HCl at temperature range 25-55o C utilizing the conventional weight loss, open circuit potential (OCP) , linear and Tafel polarization techniques. The assessment of (AE Pom P and Ros) against different microorganisms has additionally been providing by using selected biocide. Moreover the structure of (AE Pom P and Ros) is analyzed by GC-MS spectra.The optimum dose of biocide which showed good stability for the corrosion inhibitor for more than one year , diminishes the inhibition efficiency for about 20% due to its slightly acidic in nature (pH=4).The inhibition efficiency was found to increase with increasing concentration of the inhibitor and with decreasing temperature. The adsorption of (AE Pom P and Ros) on the mild steel surface obeys the Langmuir adsorption isotherm. Polarization studies indicate that the (AE Pom P and Ros) is mixed type inhibitor. The thermodynamic functions of adsorption processes were calculated from weight loss at different temperatures data and were used to analyses the inhibitor mechanism. The surface morphology of the mild steel specimens was evaluated using SEM and EDAX analysis.

Spermatocytic seminoma (SS) is a distinct testicular germ cell tumor, representing less than 1% of testicular cancers. The clinical features that distinguish (SS) from classical seminoma (CS) are an older age at presentation and a reduced propensity to metastasize. Currently, the management (SS) has changed to the increased use of surveillance, provided that there are no risk factors which may predict recurrence. Here, we report an additional case of SS and present a comprehensive relevant literature review concerning current clinical, histopathological, and therapeutic features.

It is well known that a dynamical system is a concept in mathematics where a fixed rule describes how a point in a geometrical space depends on time. A mathematical models is a precise representation of a system's dynamics used to answer questions via analysis and simulation. Mathematica models allow us to reason about a system and make predictions about who a system will behave. Contact geometry is the odd-dimensional analogue of symplectic geometry. It is close to symplectic geometry and like the latter it originated in questions of classical and analytical mechanics. If contact geometry is considered as a symplectic geometry, it has broad applications in mathematical physics, geometrical optics, classical mechanics, analytical mechanics, mechanical systems, thermodynamics, geometric quantization and applied mathematics such as control theory. It is well known fact that one way of solving problems in classical mechanics occur with the help of the Hamilton equations. Hamiltonian method is particularly important because of its utility in formulating quantum mechanics. In this study, Hamilton equations as representive the object motion were found on a contact 5-manifolds. Also, implicit solutions of the differential equations found in this study are solved by Maple computation program.

Unsteady MHD flow through porous medium past an impulsively started inclined plate with variable temperature and mass diffusion in the presence of Hall current is studied here. The fluid considered is gray, absorbing-emitting radiation but a non-scattering medium. The Governing equations involved in the present analysis are solved by the Laplace-transform technique. The velocity profile is discussed with the help of graphs drawn for different parameters like thermal Grashof number, mass Grashof Number, Prandtl number, Hall current parameter, permeability parameter, magnetic field parameter and Schmidt number, and the numerical values of skin-friction have been tabulated

This study was carried out to assess the performance, haematological, biochemical indices and bacteria load of broiler chickens fed diets supplemented with copper sulphate (CuSO4) at 0%, 100ppm, 200ppm and 300ppm inclusion levels. A total of one hundred and twenty (120) broiler chicks were careful selected and assigned to four (4) dietary treatments. The experiment was performed in three (3) replicates with ten (10) chickens per replicate making a total of thirty (30) chicks per diet. The birds were randomly selected using the Completely Randomized Design (CRD). The birds were fed ad libitum and given clean and cool water. At the end of the feeding trial, at four (4) weeks, birds fed diet 1 had the highest total fed intake (g/bird) of (34.64) and at 8 weeks, diet 2 containing 100ppm of copper sulphate has the highest feed intake (g/bird) of (180.67). The highest total weight gain (g/birds/day) in birds fed diet 2 containing 100ppm CuSO4 (1632.96) at eight (8) weeks of age. The highest feed conversion ratio was observed in the birds fed diet 3. The results obtained showed that all the haematological indices measured were not significantly (p>0.05) influenced by the treatments as the birds fed the supplemented diets were not different from birds fed the control diet which fall within the normal range. The serum biochemical values showed that cholesterol, albumin, total protein, bilirubin, aspartate aminotransferase (AST), Alanine aminotransferase (ALT), Alkaline phosphate (ALP), creatinine and globulin were not significantly affected by the dietary treatment. The blood cholesterol level of the birds ranged between 25.09g/l in the 100ppm CuSO4 inclusion to 40.12g/l in the control diet. A decrease at 100ppm CuSO4 inclusion level was observed followed by an initial increase in blood cholesterol was recorded in 200ppm and 300ppm CuSO4 inclusion level. The fact that values obtained for both alkaline phosphatase and globulin concentration did not differ significantly among treatment means showed that the utilization of CuSO4 in the diets of broiler birds will have no detrimental effects on their physiological functions. The bacterial load of liver, spleen and duodenum in birds fed diets 1, 2 and 3 decreased as the levels of inclusion of CuSO4 increases but got higher in those fed diet 4.

Both Rhynocoris marginatus (F.) and Coranus spiniscutis are polyphagus predator of agriculture important insect pests, collected from Deoria agroecosystem and under light source, Gorakhpur respectively, during 2012-2013. To determine the olfactory preference of these polyphagus predators towards one prey over another, choice based experiments were conducted in the laboratory by using Y-shaped olfactometer. The distant ends of the first two tubes of the olfactometer was used for keeping two different prey types whereas the third tube end used for introducing the predator. R.marginatus was evaluated against the African cluster bug, Agonoscelis tuberula Stål, (Hemiptera: Pentatomidae) and Hadda beetle, Epilachna vigintioctopunctata (Coleoptera: Coccinelidae), whereas C. spiniscutis against Raphidopelpa foveicellis (Coleoptera: Chrysomelidae) and Chryrocoris stolli (Hemiptera: Scutelleridae). R. marginatus was found to be more responsive to African cluster bug (60%) followed by Hadda beetle (50%) and Coranus spiniscutis strongly preferred Raphidopelpa foveicellis (91.67%) followed by Chryrocoris stolli (8.33%). In these observations, the preference of both preys during 24 hours by C. spiniscutis was converted into percentage value. R. marginatus showed higher rostral protruding activity with African cluster bug (8.29±0.159min) than that of Hadda beetle (1.65±0.049min). This may be due to the strength of the prey’s chemical cues of one prey over another elicited a quicker approaching. Prey consumption time of R.marginatus was significantly longer with regard to African cluster bug (60±2.44 min) as compared to Hadda beetle (37±2.50 min).The results clearly showed that the prey chemical cues determine the prey selection pattern of these predators. The outcome of this result will be helpful to consider these predatory bugs as biological control agents against preferred insect species.

Jhansi is well known district of Bundelkhand region of Uttar Pradesh with a geographical area of 502.75 thousand hectares. The population of the city is near about 4 lack for the last two decades due to mismanagement of traffic systems and mushrooming of vehicles chock most of the street and road of the city which lead to significant increase in air pollutants. In the present study, ambient air quality was monitored by high volume sampler in Jhansi city of central India. The six sampling sites were classified in different zones i.e. commercial, residential and sensitive and important ambient air quality parameters (RSPM, SOx and NOx) were monitored on hourly basis from January to June 2014. The results revealed that the concentration of the SO2, NO2 and RSPM from all sampling sites were ranged between 9.4 to 12.7 µg/m3, 20.5 to 34 µg/m3, 258.7 to 273 µg/m3 respectively. All the parameters (SO2, and NO2) were found below the permissible limits of NAAQS (National Ambient Air Quality Standard) except RSPM in the study sites.

Abstract In this work, effect of water depth on the single basin and double slope glass active solar still was studied. A solar collector is connected with solar still to convert the passive still into active. The set up was fabricated from a transparent glass .The thickness of the side glasses and bottom glasses are 8 mm and the upper slope glasses are 3.5 mm. All sides are made with same material. The bottom surface was coated with black coating. The solar still was insulated so that the heat dissipation could not take place to the surrounding. The length of the still is 1m and width is 0.5 m and depth of 10 cm was given and at this depth a slope of 150 was given. A flat plate solar collector is also added which is fabricated through Galvanised iron sheet whose thickness was 2.5 mm. It is in rectangular shape whose dimensions are (30cm x 15cm x 10cm). A copper tube is circulated with snake shape through which water is circulated. The study covers the influence of water depth of 1cm, 2cm and 3 cm with and without coal in the still productivity. The results stated that distilled water collection is highest for lower depth of 1 cm with and without coal. Even among lower depth, water with coal observed 21.9% increases in productivity in comparison with without coal.
