Weeds are the major biological constrain in DSR and its management contributes a major share in cost of production, as crop and weed emerge simultaneously and exerts competition right from the beginning of the crop. Field experiments were conducted in rabi 2013 and 2014 to study the effect of new herbicide combination, bispyribac sodium + metamifop 14% SE on weed control in DSR and their residual effect on succeeding greengram. Results revealed that the post-emergence (POE) application of herbicide combination, bispyribac sodium + metamifop 14% SE at 70 g ha -1 with wetter recorded significantly lower total weed density (25.78 and 24.19 plants m -2 respectively, during 2013 and 2014), total weed biomass (24.89 g m -2 and 34.56 g m -2 respectively, during 2013 and 2014) and higher weed control efficiency 1-14, (80.07 and 81.68% respectively, during 2013 and 2014). Application of bispyribac sodium + metamifop 14% SE at 70 g ha -1 along with wetter (100 mL ha -1 ) recorded higher grain yield of 5676 and 6388 kg ha -1 respectively, during both the years. Weedy check recorded the lower grain yield and recorded the higher weed index of 51.83 and 52.85% respectively, during both the years. Succeeding crop of greengram was not affected by the residue of bispyribac sodium + metamifop 14% SE at all the tested doses.","PeriodicalId":91221,"journal":{"name":"British journal of applied science & technology","volume":" ","pages":"1-14"},"PeriodicalIF":0.0,"publicationDate":"2017-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48688267","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the important network security measures on a campus network is the use of authentication for identification of legitimate users and one of the most widely used solution in network authentication is the RADIUS protocol. However, there are potential security vulnerabilities in the RADIUS network especially for networks using captive Galley Proof server in a captive portal environment which is 1000 ms [1]. After improving the OTP technique by integrating all the variants of OTP with the RADIUS server on a single server using the simulated ABU campus network using GNS3, the result shows a significant improvement over the above results. The results obtained shows the average response time for TOTP, CROTP and HOTP as 1.3s, 2s and 1.9s. The validation, based on the developed and simulated configuration was carried out using live servers, routers and switches and the results showed improvement over the above results the average response time for TOTP, CROTP and HOTP were obtained as 0.4s, 0.9s and 0.9s respectively. This shows significant improvement in the TOTP, CROPT and HOTP respectively. The result shows the average response time is less than the recommended 1000ms for RADIUS server response time in a captive portal environment.","PeriodicalId":91221,"journal":{"name":"British journal of applied science & technology","volume":"19 1","pages":"1-37"},"PeriodicalIF":0.0,"publicationDate":"2017-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47453930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ABSTRACT There is great concern worldwide about increased greenhouse gas emissions and the consequences of climate change. Photovoltaic solar energy emerges as an alternative source of renewable energy with low environmental impacts. Through a bibliographical review on the subject, this paper presents an analysis of the scale insertion of this energy in Brazil, demonstrating the benefits that can be generated of this technology, impediments and future perspectives. The conclusion is that Brazil has great potential for the energy generation, collaborating to reduce the environmental impacts as a reduction of the greenhouse gases emission. The barriers to introducing photovoltaic solar energy have been lack of investment, lack of more aggressive incentive programs, technological capacity and professional training.","PeriodicalId":91221,"journal":{"name":"British journal of applied science & technology","volume":" ","pages":"1-11"},"PeriodicalIF":0.0,"publicationDate":"2017-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43801190","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The conventional Arps’ models: Exponential, Harmonic and Hyperbolic, alongside with the Reciprocal and Quadratic models were used. Production data: gas production rate q and gas cumulative production G were obtained from 13 wells in the field “ABC”. Multivariate analyses were performed with the mentioned models to establish the decline constant (Di) and decline exponent (b); for hyperbolic model, of the field “ABC” in the Niger Delta region. A decline constant of 0.000064day was obtained from all the models with exception of Reciprocal model with 0.00053day for the gas field. Also, the decline exponent (b) obtained for Hyperbolic model was 0.9999. The statistical analysis: absolute error, standard deviation and coefficient of determination, of the fitted models used to ascertain the extent of their predicted values differ from the field test data results in Arps’ models: Exponential 0.1150, Original Research Article Okon et al.; BJAST, 19(1): 1-14, 2017; Article no.BJAST.31184 2 0.02666 and 0.9981; Harmonic 0.11547, 0.02665 and 0.9982 and Hyperbolic 0.11547, 0.02665 and 0.9982, respectively. Furthermore, Reciprocal and Quadratic models generated an absolute error, standard deviation and coefficient of determination of 0.09726, 0.026745 and 0.9911, and 0.0097, 0.000008 and 0.9998, respectively. Thus, the results indicate that, modern rate decline models for reservoir performance analysis can compete with the well-known Arps’ model(s). Therefore, the fitted Quadratic-based model can be used as a quick tool to analyze the reservoir performance of the gas field “ABC” in the Niger Delta region.","PeriodicalId":91221,"journal":{"name":"British journal of applied science & technology","volume":" ","pages":"1-14"},"PeriodicalIF":0.0,"publicationDate":"2017-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48262034","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
