Archana Ramesh R,M.S.R.Sekhar
International Journal of Electronics Communication and Computer Technology , 2012,
Abstract: The main objective of the work is to design SPI Master Core using Verilog and verify the code using Open Verification Methodology. Serial Peripheral Interface (SPI) is an interface that facilitates the transfer of synchronous serial data, which is engineer’s favorite for its convenience and saving system resource. SPI (Serial Peripheral Interface) is a synchronous serial data link that operates in full duplex mode. It communicates in master/slave mode where the master device initiates the data frame. Multiple slave devices are allowed with individual slave select line .Serial Peripheral Interface of symmetrical structure can be synthesized using Xilinx 12.3, and then can be simulated using Questasim 10.0b. It is a popular interface used for connecting peripherals to each other and to microprocessors.

Pakistan Journal of Biological Sciences , 2003,
Abstract: An experiment was conducted with 120, seven-day old Vencobb commercial broiler chick feeding ad libitum upto 42 days of age on 4 different iso-nitrogenous and iso-energetic diet formulated by replacing dietary sesame oil cake (SOC) by duckweed (DW) to have its effect on performance of broilers. Live weight, feed conversion and profitability increased when sesame oil cake was partially replaced by duck weed. Complete SOC replaced diet significantly reduced live weight gain, feed intake, feed conversion and profitability, as compared with partial replacement of SOC by duckweed and SOC based control diet. Partial replacement of SOC by DW did not affect survivability of broiler. So it might be concluded that replacement of costly SOC partially by cheaper unconventional DW in broiler diet resulted in increased profitability. Therefore, cheaper duckweed could be practiced in formulating economic balanced diet for broiler.

Pakistan Journal of Biological Sciences , 2005,
Abstract: Antibiogram study and plasmid profile analyses were conducted to find out the correlation of the recently isolated Salmonella organisms of Bangladesh. Antibiogram study revealed that the isolates were highly sensitive to Ciprofloxacin, Cephalexin and Kanamycin. In the plasmid profile analysis it was observed that out of 4 isolates of Mymensingh district (M1 to M4), 3 isolates showed 3 plasmid bands in each and 1 isolate showed 4 plasmid bands. The estimated size of the plasmid bands of M1, M2, M3 and M4 were (33.5, 24.50, 4.0, 3.0); (33.5, 3.0, 1.0); (33.5, 3.0, 1.0) and (5.0, 4.0, 1.8) kb, respectively. On the other hand among the isolates of Feni district (F1 to F9), 6 isolates (F4, F5, F6, F7, F8 and F9) showed 5 number of plasmid bands in each and the estimated plasmid band size were same (33.5, 5.0, 4.0, 2.0, 1.8). The plasmid bands of other 3 isolates (F1, F2 and F 3) were found to be different and the estimated size were recorded as 4 (33.5, 5.0, 1.6, 1.5); 3 (33.5, 1.6, 1.5) and 1 (0.7), respectively. Among the isolates of Dhaka district (D1 to D11); no plasmid band was found to be detected in 3 isolates (D2, D5 and D6). The number of plasmid bands of other isolates of D1, D3, D4, D7, D8, D9, D10 and D11 were 4 and the estimated size were determined as (33.5, 15.0, 2.0, 1.0); 5 (33.5, 15.0, 3.0, 2.0, 1.0); 5 (33.5, 5.0, 4.0, 1.8, 1.3); 3 (33.5, 3.0, 1.0); 3 (33.5, 3.0, 1.0); 1(33.5); 2 (33.5, 3.0) and 2 (33.5, 4.0) kb, respectively. All these isolates were tested for antibiotic sensitivity against 8 commonly used antibiotics belonging to different groups. From the antibiogram study it was revealed that all the isolates of Mymensingh and Dhaka district were 100% resistant to Cloxacillin and among the isolates of Feni district 100% were resistant to Erythromycin and Cloxacillin. Plasmid profile analysis of the isolated Salmonella organisms revealed that the isolates carrying multiple plasmids which might be the cause of various degree of antibiotic resistance.

Journal of Emerging Trends in Computing and Information Sciences , 2011,
Abstract: In this paper, a novel design of small sized, low profile coaxial fed patch antenna is proposed for BLUETOOTH applications at 2.4GHz frequency. The patch shape is similar to and different parameters like return loss, VSWR, gain along Θ, directions, radiation pattern in 2-D and 3-D, axial ratio, E and H Field Distributions, Current Distributions are simulated using HFSS 13.0. The measured parameters satisfy required limits hence making the proposed antenna suitable for BLUETOOTH applications in 2.4GHz band.

Abstract: The aim of the study is to detect the causes of vaccination failure in chickens against IBD in Bangladesh. One selected local field IBDV isolate, one commercially available live attenuated IBDV vaccine Bur-706 (RP) and one killed IBDV vaccine Gumboriffa (RP) were used in this study. A total of 100 chicks (Star brow) of 0,7,14,21 and 28 days age group (taking 20 in each group) were used for study the serologic response with a selected local field IBDV isolate. Similarly two other vaccines were vaccinated in each 100 chicks of similar age groups. After collection of sera weekly for upto six weeks from all groups of birds they were subjected to SNT, PHA test and AGPT against a specific IBDV antigen. Through this investigation it is found that the local field IBDV isolate demonstrate higher serologic response than that of commercially available live or killed IBDV vaccines. So, it may be concluded that the commercially available imported vaccines can not induce sufficient immune response to protect the chickens in Bangladesh. It may be due to degradation of the vaccine quality during transportation or in a new environmental condition or due to antigenic dissimilarities among the local field virus and the imported vaccines.

Abstract: group c rotaviruses are fastidious in their in vitro cell culture requirements. recent serosurveys indicate that antibody to group c rotavirus is present in 3-45% of the human population in certain geographic locations, suggesting that rotavirus group c infection is more prevalent than previously believed and that the low rate of detection of these agents is probably due to the lack of sensitive diagnostic assays. from march to december 1994, 406 fecal specimens were collected from children under five years of age who were outpatients at the emergency services of nine public hospitals in brasília, federal district, brazil. in addition to the samples from children, one public outpatient unit requested virological investigation of a stool sample from an hiv-seropositive adult male with diarrhea of sudden onset. all samples were analyzed by enzyme immunoassay for group a rotavirus and adenovirus (eiara) and by polyacrylamide gel electrophoresis (page). one hundred and seven (26%) were positive for group a rotavirus. four samples from children and the sample from the hiv-seropositive patient, although negative by eiara, showed a group c rotavirus profile by page and were positive for rotavirus by electron microscopy. using specific vp6 and vp7 primers for group c rotavirus, a reverse transcriptase-polymerase chain reaction (rt-pcr) was performed and products were detected by agarose gel electrophoresis and ethidium bromide staining. these products were confirmed to be specific for group c rotavirus by using digoxigenin-oligonucleotide probes, southern hybridization and chemiluminescent detection. the five positive group c rotavirus samples were detected in august (3 samples) and september (2 samples). to the best of our knowledge, this is the first report of group c rotavirus detected in the federal district, brazil and in an hiv-seropositive patient with acute gastroenteritis.
