| 1 | Effects of live yeast on differential genetic and functional attributes of rumen microbiota in beef cattle显示文摘Several studies have evaluated the effects of live yeast supplementation on rumen microbial population;however,its effect on differential microbial genes and their functional potential has not been described. Thus, this study applied shotgun metagenomic sequencing to evaluate the effects of live yeast supplementation on genetic and functional potential of the rumen microbiota in beef cattle. Eight rumen-cannulated Holstein steers were randomly assigned to two treatments in a cross-over design with two 25-day experimental periods and a 10-day wash-out between the two periods. The steers were housed in individual pens and fed 50% concentrate-mix and 50% red clover/orchard hay ad libitum. Treatments were(1) control(CON;basal diet without additive) and(2) yeast(YEA;basal diet plus 15 g/d of live yeast product). Rumen fluid samples were collected at 3, 6, and 9 h after feeding on the last d of each period. Sequencing was done on an Illumina Hi Seq 2500 platform. Dietary yeast supplementation increased the relative abundance of carbohydrate-fermenting bacteria(such as Ruminococcus albus, R.champanellensis, R. bromii, and R. obeum) and lactate-utilizing bacteria(such as Megasphaera elsdenii, Desulfovibrio desulfuricans, and D. vulgaris). A total of 154 differentially abundant genes(DEGs) were obtained(false discovery rate < 0.01). Kyoto Encyclopedia of Genes and Genomes(KEGG) annotation analysis of the DEGs revealed that 10 pathways, including amino sugar and nucleotide sugar metabolism, oxidative phosphorylation, lipopolysaccharide biosynthesis, pantothenate and coenzyme A biosynthesis, glutathione metabolism, beta-alanine metabolism,polyketide sugar unit biosynthesis, protein export, ribosome, and bacterial secretory system, were enriched in steers fed YEA. Annotation analysis of the DEGs in the carbohydrate-active enzymes(CAZy) database revealed that the abundance of genes coding for enzymes belonging to glycoside hydrolases, glycosyltransferases, and carbohydrate binding modules were enriched in steers fed YEA. These results confirm the effectiveness of a live S. cerevisiae product for improving rumen function in beef steers by increasing the abundance of cellulolytic bacteria, lactic acid-utilizing bacteria, and carbohydrate-active enzymes in the rumen. | Ibukun M.Ogunade Jerusha Lay Kenneth Andries Christina J.Mc Manus Frederick Bebe | 2019 | Journal of Animal Science and Biotechnology2019，10，4： | 11 |

| 4 | Principal components methodology-A novel approach to forecasting production from liquid-rich shale(LRS)reservoirs显示文摘With increasing global demand for energy,the importance of unconventional shale oil and gas research cannot be over-emphasized.The oil and gas industry requires rapid and reliable means of forecasting production.Existing traditional decline curve analysis(DCA)methods have been limited in their ability to satisfactorily forecast production from unconventional liquid-rich shale(LRS)reservoirs.This is due to several causes ranging from the complicated production mechanisms to the ultra-low permeability in shales.The use of hybrid(combination)DCA models can improve results.However,complexities associated with these techniques can still make their application quite tedious without proper diagnostic plots,correct use of model parameters and some knowledge of the production mechanisms involved.This work,therefore,presents a new statistical data-driven approach of forecasting production from LRS reservoirs called the Principal Components Methodology(PCM).PCM is a technique that bypasses a lot of the difficulties associated with existing methods of forecasting and forecasts production with reasonable certainty.PCM is a data-driven method of forecasting based on the statistical technique of principal components analysis(PCA).In our study,we simulated production of fluids with different compositions for 30 years with the aid of a commercial compositional simulator.We then applied the Principal Components Methodology(PCM)to the production data from several representative wells by using Singular Value Decomposition(SVD)to calculate the principal components.These principal components were then used to forecast oil production from wells with production histories ranging from 0.5 to 3 years,and the results were compared to simulated data.Application of the PCM to field data is also included in this work. | Ibukun Makinde W.John Lee | 2019 | Petroleum2019，5，3： | 2 |

| 17 | Assessment of Child Labour Practices among Market Women and Food Sellers in Ife Central Local Government Area of Osun State,Nigeria显示文摘The study examined the forms of child labour practices common among market women and food sellers in Ife Central local government area of Osun State.It also determined the awareness level of market women and food sellers on the existing child labour law in Nigeria and finally examined factors contributing to child labour practices among market women and food sellers.The study employed the descriptive research of the survey type.The study population consisted of market women and food sellers in Ife Central local government in Osun State.The sample consisted of 170 market women and 80 food sellers in conveniently selected five markets in the study area.The researchers developed three research instruments for this study,namely:Knowledge of Child Labour Questionnaire(KCLQ),Forms of Child Labour Practices Questionnaire(FCLPQ),and Factors Contributing to Child Labour Questionnaire(FCCLQ).The three instruments were validated by the investigators,using Cronbach alpha which yielded 0.79,0.77,and 0.78 values for KCLQ,FCLPQ,and FCCLQ respectively.Data collected were analyzed by using simple percentage and Relative Importance Index.The results among others showed that domesticlabour ranked the first significantly influential forms of child labour practiced among market women and food sellers in Ife Central local government,Osun State with RII analysis of 0.810 and 0.850 respectively.The study therefore concluded that majority of the respondents have low awareness level on the existing child labour law hence government should intensify the creation of awareness of the child labour law among market women and food sellers in Ife Central local government,Osun State. | Babatunde Adeniyi Adeyemi Adeyemi Ayobami Ebo Ibukun Diadem Adeyemi | 2021 | Psychology Research2021，11，4： | 0 |
| 18 | Preservative Effect of Newbouldia laevis (Boundary Tree) Leaf Extract on Shelf-Life of Fresh Chicken Meat under Tropical Conditions显示文摘The shelf life of chicken meat has been rapidly reduced as a result of high environmental temperatures prevalent in the tropics which favored the activities of spoilage micro-organisms,and reactive oxygen species that function in oxidative damage.Newbouldia laevis(N.laevis)possess valuable antioxidant and antibacterial properties.However,information on the effect of aqueous extracts of dry and wet leaves of N.laevis on preservation of fresh chicken meat under tropical condition is scanty and thus,investigated.Broiler chicken meat(10kg weight)was obtained immediately after slaughter and were randomly allotted to three treatments(T1-control;T2-aqueous extract of wet leaves of N.laevis;and T3-aqueous extract of dry leaves of N.laevis)in a Randomized Complete Block Design.Tropical plant,such as Newbouldia laevis with relatively high resistance to heat stress,possesses viable bioactive compounds that can lower the growth of spoilage micro-organisms and activities of reactive oxygen species on fresh chicken meat under tropical conditions for 48 hours.Hence,poultry farmers in developing nations with fluctuating power supply can adopt the quick meat shelf life enhancement technique,while commercial poultry farmers across the globe can embark on product fortification using extracts of Newbouldia laevis. | Oluwabukola Rashidat Popoola Ibukun Olukorede Popoola Olubunmi Olusola | 2020 | Journal of Zoological Research2020，2，1： | 0 |
