Geotechnical and geochemical assessment of natural sands being used as fine aggregates for construction purposes in Ahanta West and its Environs was carried out, as well as addressing the environmental problems associated with the exploitation of these sand through the sand winning activities. The results from geotechnical and geochemical tests were bench marked with British, American and Ottawa Standards for testing materials. Representative samples were taken from five different sand winning sites namely, Pompuni, Agona Banso, Fretsi, Tumentu stream and Fretsi river. The geotechnical tests carried out were specific gravity, grain size analysis, moisture content, silt content, permeability test using the constant head permeameter method. The photometer (Hydro Test HT 1000) was used to determine silica, sulphate and chloride concentrations in the sand samples. The oxides for the geochemical analysis were determined using the X-ray fluorescence (XRF) method. The results from the study areas showed that except for Fretsi, the specific gravity, grain size analysis, moisture content, silt content and permeability tests were within the acceptable range for natural sands. Sand samples from Pumponi and Agona Banso had the required Cu and Cc values of being well graded. Sulphate and chloride concentrations were within standards for all the samples;however, silica was low for all the samples. Fe2O3, Al2O3, MnO and Na2O did not meet the Ottawa sand standard. Natural sand is not recommended to be used for construction purposes however, these sands may be treated or blended if it is to be used for construction purposes. There are serious environmental implications for the sand-winning activities in the study areas suc

Nonnegative matrix factorization (NMF) is a relatively new unsupervised learning algorithm that decomposes a nonnegative data matrix into a parts-based, lower dimensional, linear representation of the data. NMF has applications in image processing, text mining, recommendation systems and a variety of other fields. Since its inception, the NMF algorithm has been modified and explored by numerous authors. One such modification involves the addition of auxiliary constraints to the objective function of the factorization. The purpose of these auxiliary constraints is to impose task-specific penalties or restrictions on the objective function. Though many auxiliary constraints have been studied, none have made use of data-dependent penalties. In this paper, we propose Zellner nonnegative matrix factorization (ZNMF), which uses data-dependent auxiliary constraints. We assess the facial recognition performance of the ZNMF algorithm and several other well-known constrained NMF algorithms using the Cambridge ORL database.

Background:Urogenital schistosomiasis is a parasitic infection of public health importance that affects over 112 million people *** study aimed at assessing the urogenital schistosomiasis prevalence and risk factors of transmission around Mape dam suburds in Malantouen district,West,***:The study was conducted using semi-structured pretested questionnaires to collect socio-demographic and ecological *** samples were also collected and used to confirm the prevalence of schistosomiasis in consented school-aged children in four primary schools between March-July ***’samples around the dam surburbs were also collected for taxonomy characterization and species *** were compiled and quality control assessed and analysed using SPSS version 17 and Epiinfo data 3.1.P<0.05 was considered statistical ***:Questionnaires were administered to 229 pupils,with gender ratio of 1.04(m/f).The prevalence of schistosomiasis haematobium was 16.6%.Mambonko school site,which is the closest to the dam suburbs,registered the greatest prevalence rate of 40%.The age group beween 10-13 years was the most infected(18.3%)and boys were more infested than girls(21.0%vs.15.5%).Haematuria,urination pain,school absentiesm and poor performance were the major recorded complications in 39.5 and 26.3%males to female *** rate gender disparity documented is still poorly understood and Bulinus truncatus collected from Mambonko suburb as potential snail intermediate host requires further ***:Authors advocated that schools and dam suburds sustained and innovative community-based surveillance and response targeted interventions implementation are needed to inform and support decisionmaking policy,but also in improving effective contextual behavioural communication changes and MDA improved uptake measures on national schistosomiasis control and elimination in Cameroon.

In today＇s modem world, a will to succeed is inextricably linked with the acquisition of profit, while sports competition turns into an aggressive fight for the result and prestige. The athletes in professional sports, where victory is imperative, often treated as just another object and an obstacle to be overcome. Violence in sports performed primarily athletes themselves. In sports games can be applied aggressive tactics, but the use of violence is considered to be beyond the scope of what is considered to be the good behavior of an athlete. Athletes decide on violence sometimes with a clear goal of hurting the opposing player, and sometimes only for intimidation, in order to win. Extreme exercise, accompanied by great hardships and frequent injuries, are not always sufficient to achieve the required and expected results, and more and more athletes turning to the use of prohibited doping substances, thus trying to improve their own capabilities.

Background： Direct ZN （Ziehl-Neelsen） sputum smear microscopy for diagnosis of TB （tuberculosis） has low sensitivity, especially in TB/HIV co-infected patients. Sputum concentration by bleach （NaOCI） with sedimentation has been used to increase the sensitivity of sputum smear microscopy in many settings but with varying results. Objective： To determine whether bleach plus centrifugation significantly improves the detection of AFB （acid-fast bacilli） in ZN smear-negative sputum specimens. Methods： Three hundred and seventy sputum specimens were collected from new TB suspects attending a Nairobi referral district hospital and processed for direct microscopy using ZN technique and culture on Lowenstein Jensen Media. All smear-negative specimens were treated with 3.5% bleach and left to stand for 30 min before centrifugation. The bleach treated smears were processed and examined using ZN technique. Results： Of the 370 specimens, 200 （54%） were positive culture. The number of sputum samples that were smear-positive by direct ZN was 138 （37.2%）, with a sensitivity of 66%. After treatment of direct ZN smear-negative specimens with 3.5% bleach and centrifugation, the total number of AFB smear-positive samples increased to 171 with an increase in sensitivity of 66% to 81.1% （15.1%）. Conclusion： In this study, bleach with centrifugation significantly increased the yield of sputum smear microscopy. Further evaluation of these techniques in routine programmes is required especially in settings where the burden of TB/HIV is high.
