Injera is the staple food to Ethiopians mostly prepared from tef as the main ingredient. This was a research done by partially substituting tef, relatively expensive flour, by cassava flour and evaluated its injera making quality. Tef and cassava flours were mixed in all possible ratios at 10% intervals. Functional properties, sensory evaluations and proximate compositions were estimated using standard methods. Except water absorption capacity, all other functional properties were significantly varied with changing proportion of tef and cassava flours. The sensory acceptability of tef-cassava injera was significantly decreased in all parameters with increasing proportion of cassava flour. Tef-cassava injera contained 7.59 to 9.41% moisture, 0.65 to 1.87% ash, 0.40 to 1.02% crude fat, 3.79 to 11.89% protein, 1.10 to 3.05% crude fiber, 75.73 to 83.54% carbohydrate and 349.45 to 364.45 energy/100g. As cassava flour substitution levels increase, most flour functional properties increased, whereas sensory characteristics and proximate composition parameters (protein, fat, ash and energy) decreased. It was concluded that up to 40% cassava could be incorporated with tef to make injera with slightly acceptable sensory quality and fair nutritional value. Further research is required with regard to quality of injera as affected by other factors like maturity stages of cassava and the like.","PeriodicalId":284331,"journal":{"name":"American Journal of Bioscience and Bioengineering","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130758194","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}

It is characterised by the presence of persistent albuminuria and a reduction of the Glomerular Filtration Rate (GFR) in diabetic condition. No study has revealed the prevalence of DKD in Cameroon. This cross-sectional study was conducted in Buea and Ngaoundere to determine the prevalence of DKD and characterize its biochemical profile in diabetic population under medical care. A total of 250 diabetics were enrolled with a mean age of 56.78±12.06 years, out of which 59.6% were diagnosed with Chronic Kidney Disease (CKD), 32.8% presented micro-albuminuria and 3.6% were diagnosed with macroalbuminuria. The prevalence of DKD was 15.2% out of which 78.9% were females (p=0.002). The prevalence of the co-morbidity hypertension and DKD was 8.8%. Significant association was found between DKD and two variables: female gender (OR: 2.28 (1.21-4.29); p=0.002) and hyper-creatinemia (OR: 3.47 (2.13-5.66); p < 0.001). The high prevalence of micro-albuminuria found in this study may reflect a high frequency of micro-albuminuria in diabetic population in Cameroon. This study is the first, to assess DKD in Cameroon according to the ADA consensus on CKD and diabetes. The findings showed that, diabetic complication is a serious problem in Cameroon and, more actions should be taken to improve its management.","PeriodicalId":284331,"journal":{"name":"American Journal of Bioscience and Bioengineering","volume":"07 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127182012","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}

Composting is thus, environmental friendly option for utilization of this waste. Therefore this study was to evaluate some physicochemical parameters of compost produced from coffee pulp with cow dung and enset leaf (Ensete ventricosum).Results: Treatments were built in randomized complete block design with proportions of treatment one (90% of coffee pulp and 10% of top soil), treatment two (65% of coffee pulp, 25% of cow dung and 10% of top soil), treatment three (65% of coffee pulp, 25% of enset leaf and 10% of top soil) and treatment four (50% of coffee pulp, 20% of cow dung, 20% of enset leaf and 10% of top soil).

The experiment was designed following a randomized complete block (RCB) with 21 cane genotypes in three replications. Each plot consisted of five dual rows of ten meters with 0.5 and 1.90 m of inter-row spacing, i.e. 95 m2 per plot and about 6,000 m2 for the whole experiment. It was carried out on a commercial sugarcane plantation of Ferke 2 located in the northern part of the country, over two seasons (plant cane and first ratoon) as an early-season crop from, November 18, 2016 to November 15, 2018. Over each micro-plot, data based on different agro-morphological traits were collected at harvest from three central dual rows. The study showed that most relevant traits in genotype clustering were related to juice quality (recoverable sucrose, sucrose content, purity), yields and yield components (millable stalk number/ha, stalk height, stalk diameter, internode number). Based on sugar yields, four genotypes equivalent to the check (R579), namely KQ228, R97-6177, R99-4064 and KQ236, were found promising for the next advanced selection stage with, respectively, 19.2, 17.7, 17.3 and 16.9 t sugar/ha. Their cane yield performances ranged from 147.7 to 170.8 t/ha compared to 170.7 for the check and belong to 3 clusters genotypes over the eight determined.

Farmers utilize various protection strategies and methods to minimize the level of damage by pests, but among protection strategies pesticide application is the predominant method. There is high dependency of farmers on pesticide control of pests in fruits and vegetable production. Pesticide application encourages farmers to rely more on pesticides than on other pest control methods because of quick results obtained. This will result in accumulation of pesticide residues on the crops. Pesticide residue refers to pesticides that may remain on or in food after they are applied to food crops. Hence pesticide residue includes the pesticide that is remained in the sprayed produce such as fruits and vegetables and bioaccumulation in animals and products such as fish, meat, eggs and dairy. Pesticides used on fruits and vegetables leave residues on the exposed crops which expose human beings to adverse health effects. The continuous use of pesticides in fruits and vegetables as practiced by farmer’s poses a health risk to consumers and may lead to higher pesticide residues. Organochlorine and organophosphate pesticides which are the most hazardous and banned chemical groups are still in use in Ethiopia. Good pesticide monitoring and program to evaluate consumer risk for the Ethiopian people is mandatory.","PeriodicalId":284331,"journal":{"name":"American Journal of Bioscience and Bioengineering","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129673287","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}
