Theileriosis is a bovine haemoprotozoal infection caused by Theileria species. It is a tick transmitted haemoparasite and the disease can develop as clinical or subclinical infections. This study was carried out in order to determine Theileria infection by Polymerase Chain Reaction in cattle and buffaloes in a National Livestock Development Board farm at Polonnaruwa, Sri Lanka. Forty-one blood samples were collected from the herd of diseased and non diseased cattle and buffaloes. Packed cell volume of each blood sample was analyzed using microcenrifugation which revealed that 85.7% (18/21) cattle and 20% (4/20) buffaloes had PCV values below the average
This paper presents a miniaturized planar circular disc UWB antenna design for wireless communications. Printed on a dielectric substrate and fed by 50Ω microstrip line with truncated ground plane, the proposed antenna has been demonstrated to provide an ultra wide 10dB return loss bandwidth with satisfactory radiation properties. The special structure reduces the spatial volume and it is used to realize the miniaturization of the antenna. Ansoft High Frequency structure Simulator (HFSS) software tool has been employed for obtaining the simulation results. The return loss, voltage standing wave ratio (VSWR), radiation patterns and current distributions of the antenna are discussed.
Alkali, Alkaline earth and transition metal ions doped L-proline single crystals were grown by solution growth technique. Due to variation in the nature of dopant, there is a modification in the growth habit, nonlinear optical property and mechanical hardness of the doped crystals. Fourier transform infrared (FTIR) spectra reveal strong absorption bands occur due to the presence of L-proline. UV–visible spectra show an improvement in the optical transmittance while doping on Lproline. The unit cell parameters and cell volume are obtained by powder X-ray diffractometer. Effect of dopant on the crystal defect on the grown crystals was characterized by Optical Microscopy. Anti microbial study of the grown crystals were analyzed using gram positive and gram negative micro organisms.
Today, computing becomes steadily more important and more used. Cloud computing has appeared as an accepted computing model for processing very large volume of data. Cloud computing is an unavoidable trend in the future computing development of technology. In this paper, we have discussed the computing taxonomy and their relationship with cloud computing.
Microwave assisted activated carbon from rubber seed pericarp (RSP) was successfully produced by using three different chemical activating agents of ZnCl2, KOH, and H3PO4. The process was carried out at 600W of irradiation power for 20 min. The absorption study was applied for these modified activated carbon samples under cationic methylene blue (MB) dye. The Carbonisation of RSP using ZnCl2 (RSP-ZnCl) as activating agent was found the best as compared among the rest which high BET surface area, total pore volume and iodine number were 1689.00 m²/g, 0.9321cc/g and 883.49 mg/g respectively. The adsorption capacity of RSP-ZnCl under MB was ca. 297.24 mg g -1 . This finding showed the feasibility of preparing activated carbon from RSP using ZnCl2 activating agent via by microwave carbonisation technique.

Social media refers to the means of interactions among people in which they create, share, and exchange information and ideas in virtual communities and networks. The growth of Information and Communication Technology (ICT) has resulted in an enormous volume of security related information present on the web largely when it comes to social media networks. Therefore, with the changing face of cyber security, although it is difficult, it was found that detecting the potential cyber-attacks or crimes is possible and feasible with the vast improvements in ICT. Cloud computing uses ICT resources that are delivered as a service over a network which has opened a promising opportunity across the globe thus resulting a greater popularity of e-commerce. The proposed framework is developed to manage risks of social media networks using the attack tree method which is used to model the risk of the system and identify the possible attacking strategies which the adversaries may launch.
True that boggles the mind of various, that needs to be accurate, people who find themselves reaching out to their retirement years phase is investment stability. Within the continuing change on earth market, safe-guarding your put up pension income policy together with the volume perceived in order to be accomplished will get unclear. While there is a strategy to virtually every obstacle, so could it has one particular. Buying natural precious in IRA is an ideal resort that can be exceptionally helpful when dealing with develop a safe submit retirement life monitory circulate.
Cattle suffering with plastic foreign body syndrome were treated surgically by rumenotomy. The pre-operative and 12 th day post operative blood and serum biochemical were recorded and compared with normal healthy cattle. Preoperatively decrease in haemoglobin, packed cell volume and total erythrocyte count was observed which was gradually increased and came to near normal state on 12 th post-operative day. There was leucocytosis, neutrophilia and corresponding lymphopenia observed in animals during pre-operative phase. The glucose, serum creatinine, serum albumin and calcium levels were found to be at lower level and total proteins, blood urea nitrogen and phosphorus at higher level in pre-operative period when compared to normal cattle. This may be due to low intake of food and water and also inflammatory condition in body due to presence of plastic foreign body.
