Now human operators do the Meter reading for the consumption of Electricity from house to house and building to building. It requires huge number of labor and takes more time to complete the process. Reading error is a common cause of human operator. Automatic Meter Reading (AMR) becomes an executable option to overcome the problems of huge time taking to get the meter readings, the measured values are in kilo watt-hours (kWh) by energy meter. The supply status of the consumer reading unit we identified the disk rotation of the energy meter. The main advantage of this system is a low cost system that produces very encouraging results and it can be implemented upon existing electro-mechanical meters so there is no need to purchasing new meters AMR is the remote collection of consumption data from customer’s utility meters over power line. Power-Line Communication (PLC) carries data on a conductor that is also used simultaneously for AC electric power distribution to consumers. PLC transmitter is responsible for transmission of data from the provider end. At the provider end, there will be the PLC receiver, which is responsible for data receiving, and this module makes an interface with computer, which is responsible for data processing.","PeriodicalId":8944,"journal":{"name":"Bioprocess Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76365354","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 benefits of this management has been noted to ensure the sustainable use of woods for fuel, honey for medicine and other human needs, fruits for eating, fodder and grasses for livestock and many other important plant resources for medicinal purposes in local communities. Deforestation and desertification caused serious damage to most of the forest areas in northern Nigeria. Many advices and practices continue to provide favourable environment for better management of the African forests. Sustainable forest management was considered as an alternative to maintains and improves the soil biodiversity, soil productivity, regeneration capacity, vitality and potential of the economic values of northern Nigerian forest trees. As part of this sustainable forest management practices, this paper, provides an outline of some key recommendations on how to improve, maintain and manage forest trees and their soil biodiversity in the region.","PeriodicalId":8944,"journal":{"name":"Bioprocess Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77950623","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}

Along this approach, laboratory concrete samples were so prepared and sent to mechanical testing, and concurrently, the inhibitive potential of the rice husks suspended in electrolyte solution (water with dissolved sodium chloride of 3.5 wt.%) was also tested by using a standard electrochemical corrosion testing technique, i.e. the powdered rice husk was added to the electrolyte solution in different dosages (1%, 2% and 3%), then the corrosion currents of the steel samples were recorded by using a three-electrode cell assemblage. In these laboratory tests a quite steady decreasing tendency could be observed in the measured corrosion current densities ( I corr ) compared to the case when the electrolyte solution did not contain any inhibitor admixture ( I corr =41.3 µA/cm 2 ; taken as the reference). For example, a corrosion current of I corr = 28.5 µA/cm 2 was measured at 1% rice husk concentration, and only I corr = 7.8 µA/cm 2 when the solution was mixed with 3% rice husk powder.","PeriodicalId":8944,"journal":{"name":"Bioprocess Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86550072","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 essence of the study was to evaluate the practical nutrient removal efficiencies of Chlorella sorokiniana and Scenedesmus obtusiusculus . The microalgae were grown on 3 different media― namely; mixture (mixed treated and untreated urine), untreated urine and control, and their nutrient removal efficiencies were investigated. Urine that has passed through the OLAND RBC system served as treated urine, and Bold’s basal medium served as the control. The OLAND RBC system was able to remove 95.7% of total chemical oxygen demand (COD), 27.1% total nitrogen, 99.7% ammonium, 88.6% total phosphorus and 89.3% ortho-phosphate from the influent urine. Low nutrient removal performance at a very high N: P molar ratios were observed in microalgae in the untreated urine. However, the nutrient removal capacities of microalgae were very high at reduced N: P molar ratios in the mixed medium. Chlorella sorokiniana was able to remove 63.2% TN and 55.8% TP at a low N: P molar ratio of 8.5:1, while Scenedesmus obtusiusculus removed 45.9% TN and 76.3% TP at an N: P molar ratio of 6.9:1. The results indicate that nutrient removal by microalgae is most efficient in mixed OLAND RBC treated and untreated urine culture. Therefore, the integration of the OLAND RBC system when designing microalgae induced wastewater treatment technologies for sanitation purposes is advocated.","PeriodicalId":8944,"journal":{"name":"Bioprocess Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72642466","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}

In this study, ten lactic acid bacteria were isolated from 7 samples of naturally fermented pineapple juice. All isolates could grow in the MRS medium pH 1.5 and reach high densities (6.80 – 6.95 log CFU/mL) after 2 h of incubation at 37°C. Moreover, Lactobacillus sp. Y1 produced highest lactic acid concentration (1.20% w/v) and identified as L. acidophilus . The different diluted ratios of pineapple juice (0, 10, 20 and 30% w/v) and different sucrose supplementations (0, 3, 6, and 9% w/v) were used for testing fermenting capacity of L. acidophilus Y1. The undiluted pineapple juice with 9% (w/v) of sucrose supplementation was found to be suitable for fermentation. Based on the results of sensory evaluation and bacterial density determination, the favorable conditions for pineapple fermentation were determined as follow: initial bacterial level at 5.0 log cells/mL, fermentation time for 36 h at 37°C. The results of storage testing showed that the suitable temperature for product storage was 4 – 6°C, bacterial density (8.06 log CFU/mL) of final product was maintained up to 3 weeks.","PeriodicalId":8944,"journal":{"name":"Bioprocess Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74407054","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}
