Likewise, the two main directions of fractures [NNW SSE (N160°E) in N S and NNE SSW (N10°E)] and two secondary directions [W E and NNW SSE (N140°E)] were present on white marble which is richer in CaO (52.65 to 55.45%) than the dolomitic one (30.15 to 31.78%). It came out that the quartzite was richer in SiO2 (95.43 to 98.86%) than shale (45.67 to 79.12%). The physical and mechanical characteristics of the white marble were: absolute density (2.77g/cm) and bulk density (2.75 g/cm). The mechanical fragmentation strength on the 6/10 mm and 10/14 mm fractions was 32% and 31%.

Due to the complex interdependence of the tasks and the fact that the productive plant changes location constantly, it is more difficult to manage injury prevention and safety in construction sites, with respect to other activities. The present study was conducted in Yucatan, Mexico, where low levels of prevention and compliance with obligatory norms have been reported. The aim was to analyze a sample of over one hundred construction accidents in building works in order to determine the causes and consequences of the lack of prevention. The risks which caused the accidents were analyzed with regard to their incidence and severity; the resulting injuries and the occupations of the workers affected were also analyzed. It was concluded that urgent measures are required in order to prevent four main risks (Concrete and masonry construction, Fall protection, Scaffolds, and Electrical); In addition, no actions were observed providing evidence that the phenomenon of lack of prevention in construction works is a priority for the authorities, companies or the trade unions.","PeriodicalId":91221,"journal":{"name":"British journal of applied science & technology","volume":"20 1","pages":"1-13"},"PeriodicalIF":0.0,"publicationDate":"2017-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42842928","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}

Methodology: Established five groups including eight persons/group in each location to carry out the questioner and evaluations were accomplished based on specific key point issue. Results: Three categories of river training structure were found at different location of the study area. Revetment with cement concrete (CC) block including 1.75 km bank protection measure from erosion due to high velocity tidal current at Lebukhali point (0.715 km), Patuakhali town protection point 2 (0.62 km) and Khepupara Bandar & town protection (0.42 km). Among them Lebukhali point was found more offensive comparing with others point. The level of risk of all structures was averages under low to medium except Lebukhali point. Conclusion: The training structures were found moderately stable due to maintenance and effectively acting as qualitative benefit for inhabitants in socio-economic aspect.","PeriodicalId":91221,"journal":{"name":"British journal of applied science & technology","volume":"19 1","pages":"1-12"},"PeriodicalIF":0.0,"publicationDate":"2017-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44089740","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 experiment was a randomized complete block design (RCBD), replicated three times and treatments used were: Sole Maize (M), Desmodium (D) and Soybeans (S); Maizesoybeans intercrop (MS), Maize-Desmodium intercrop (MD), Maize Strip cropped with Soybean (MS 2:4) and Maize Strip cropped with Desmodium (MD 2:4). Data obtained were evaluated for Organic carbon, carbon stock, Bulk density and mean weight diameter of aggregates in the soil. Results obtained show that Mono-crop (Sole) Maize treatment gave significantly higher BD than other treatments at 8WAP and 16WAP, suggesting that soils under sole maize were degraded for sustainable crop production. Organic carbon sequestered over 2014 to 2015 was least under MD and highest under MD2:4 treatments and mean carbon stock sequestered in the macro and micro aggregates was highest under MD 2:4 (28.35 t Cha -1 ) and least under MD (8.82 t Cha -1 ).
