An experiment was conducted in August 2011 using air cooler type BF3 size 2500 m3/ h have motor works with two speeds. Researcher add another water pump to work with the first water pump in order to increase the amount of water drop over pads. Water consumption (liters / hour), the internal temperature°C, external temperature°C ,the temperature of the cooling water in the bottom of the cooler°C, electrical consumption (A), and cooling efficiency were studied in this experiment. The result showed that add another water pump has highly significant effect on cooling efficiency (F1, 19 =15.98, p value = 0.0018). Furthermore, add another water pump has highly significant effect on inside temperature (19, 1=58.37, P value < 0.0001) which improve the performance of air cooler. In addition, there was a highly significant effect on water consumptions (19, 1= 26.16, P value =0.0003), which is normally add another water pump mean more water will consume that because allow to the pad to become more saturation as well as don’t left any dry spot in the pad. The only sources of the air that inter to the building will be through the wet pad, and any dry spot in the pad will allow to the hot air to pass through it that will add more heat to building. Just the time play an important role on water temperate there was highly significant effect (19, 4= 50.25, P value = <.0001), because temperature afternoon is higher than in the morning or at night that will causes increase water temperature of the air cooler.

Thevetia peruviana, cultivated as an ornamental plant and planted as large flowering shrub, belongs to the family Apocynacea. The aim of this study is to screen the phytochemicals present in the leaves of Thevetia peruviana and further analysis of the components present in it by GC- MS analysis.The leaves were sequetially extracted based on the polarity viz., hexane , acetone and methanol and subjected to phytochemical screening which revealed the presence of bioactive compounds such as alkaloids, flavanoids, cardiac glycosides, steroids, terpenoids, tannins, phenols, quinones and saponins.The GC- MS analysis of the acetone extract revealed the presence of 33 compounds. This study forms a basis for the biological characterization and importance of the compounds identified.

The purpose of this article is to examine the broad contours of Eritrea-India relations in the past two decades, and in turn to stimulate further academic and policy researches with specific focus on the opportunities and challenges. To this end, secondary and primary sources have been thoroughly referred. Eritrea-India relation was formally established when Eritrea emerged as an independent sovereign state on May 24, 1993. Since then, both countries shared multi-dimensional relations, but with very limited results. India has provided manifold assistance to Eritrea in areas, such as agriculture, education, and science and Technology. India’s engagement with Eritrea also extended to technical assistance, training and capacity development under the framework of South–South cooperation. Recent development in trade and various investment initiatives are also a reflection of the new stride in the bilateral friendship. In addition, Eritrea has been hiring a great number of skilled labour from India. However, the bilateral relations is not always without estranges. Trade imbalance, restrictive monetary and fiscal policies and Eritrea’s more closeness to China are among other fault-lines. The balance sheet of the two states bilateral relations however proves the positive gains from the current diplomatic impetus. Finally, the researchers suggested to Eritrea and India to make more effort to bit back fences against the curve of evolving bilateral relation and avoid obsolete mechanism which is purely interest driven.

Image fusion is a technique to improve the image quality. In this paper a new way is drawn to fuse two images by using max-min operations in Sugeno’s Intuitionistic fuzzy generator. It operates on image with lot of uncertainties. Firstly input images are reform into Intuitionistic fuzzy images (IFIs) and then evaluate fuzzy rules by using best entropy of input images, and IFIs are reconstructing based on black-count & white-count. This paper compares the performance of Average, Fuzzy Sets, Intuitionistic Fuzzy Sets and Sugeno’s type Intuitionistic fuzzy (proposed method) in terms of various performance measures.

Image fusion is one of the techniques in Image processing. In this paper, we are going to propose a Image fusion method based on Teaching Learning Based Optimization. Taking two multifocused images, we are going to divide them into blocks then the contrast visibility of the two image blocks then is calculated. TLBO algorithm is performed to obtain optimal coefficients and fused image is acquired finally using this Optimal Coefficients. For different set of multi focus images, different quantitative measured are calculated. Then the results of proposed method are compared with existing Particle Swarm Optimization.

We report the case of a young man aged 23, victim of an accident to type up falling penetration with thorns wood at the side of the inner right thigh. A scrotal ultrasound scan with erectile body objectified a strong allure foreign body straight. A mini-incision made at the level of the symphysis pubis allowed the removal of the foreign body.

Using concentrations of 0.0, 0.2, 0.4, 0.6 and 0.8mg diatomaceous earth (DE) 100 mL-1 larval food medium, a mean LC50 value of 0.6636mg was determined for the 3rd-instar larvae of the housefly Musca domestica. Time-course mortalities of the larvae at the determined LC50 level were assessed at 24h, 48h and 72h post-treatments. Finally, DE-induced changes in such vital reproductive attributes as egg-laying, egg-hatch, larval duration, number of dead larvae, pupal duration, number of dead pupae, number of adults emerged and female ratios from parental through F2 generations were recorded. Results indicated that DE could be used as an efficient larvicide against M. domestica and it was capable of inducing deleterious effects on all the reproductive parameters at the determined LC50. These findings have potential implications because the present DE concentration might be utilized for the control of this important vector species under household as well as field conditions.

To investigate the antihepatotoxic ability of aqueous leaf extract of Cassia auriculata on antituberculosis drug, rifampicin induced hepatotoxicity. In the present study, the aqueous leaf extract of Cassia auriculata (150, 300 and 600 mg/kg body weight) was examined for its antihepatotoxic ability against rifampicin induced liver injury. Fourty two healthy male albino wistar rats (150-180 g weight) were chosen and divided in to seven groups. Rifampicin and aqueous leaf extract were given 28 days according to the experimental design. After 28 days of treatment, hepatic serum marker enzymes, antioxidant enzymes, lipid peroxidation and liver histology were analyzed. Rifampicin induced liver damage showed significantly elevated activities of alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), cholesterol and bilirubin whereas protein level was decreased in serum. Moreover hepatic antioxidants like superoxide dismutase (SOD), catalase (CAT) and reduced glutathione (GSH) activities were decreased whereas lipid peroxidation level was increased and also necrosis, vacuolization, space formation and loss of cell boundries were observed in liver when compared with control group. Administration of aqueous leaf extract of Cassia auriculata or silymarin could significantly restored to near normal by decrease the activities of serum hepatic marker enzymes and lipid peroxidation level where as enhance the activities of antioxidant enzymes, serum protein and improving towards the normal liver hsitoarchitecture when compared with rifampicin alone treated rats. These present findings suggested that the aqueous leaf extract of Cassia auriculata exhibited antihepatotoxic ability against rifampicin induced hepatotoxicity compared to standard drug silymarin.

Abstract The present study was carried out with an aim to emphasis on the effects of radio-frequency electromagnetic radiations from cell towers on human beings. Questionnaire based survey was conducted by means of interviews and general discussions with a population size of 181 inhabitants residing in five different localities (viz., Gangondahalli, Nagarabhavi, Moodalpalya, Chandra layout, Guddadahalli) of Bangalore south taluk. The participants themselves filled the self-administered questionnaire by entering their response data on the health effects faced due to establishment of mobile towers. Exposure assessment was based on the distances from base stations (less than 10 m, 10-50 m, 50-100 m, 100-200 m, 200-300 m, > 300 m) and their location in relation to the antennas (facing, beside, behind, beneath in the case of antennas placed on rooftops). Based on results congregated, it was evident that headache, irritability, nausea, appetite loss, discomfort, sleep disturbance, depression, memory loss difficulty in concentration and dizziness, etc., are more frequently observed symptoms of ill-health in the exposed groups. It is concluded that the cell phones and cell phone tower radiation are a strong risk factor for all the adverse health effects.

Equations governing the flow of a fluid with variable viscosity through an isotropic porous structure are derived using the method of intrinsic volume averaging. Viscosity of the fluid is assumed to be a variable function of pressure, and the effects of the porous microstructure are modelled in terms of Darcy resistance, Brinkman shear term, and Forchheimer effects.
