2Effects of biochar amendment and nitrogen fertilization on soil microbial biomass pools in an Alfisol under rain-fed rice cultivation显示文摘Field studies were conducted over 2 years to determine the response of soil microbial biomass pool to biochar and N fertilizer combinations in a rain-fed rice cropping system.Biochar was applied at four doses:0 t ha^(−1),3 t ha^(−1),6 t ha^(−1) and 12 t ha^(−1) in combination with N fertilizer at four rates:0 kg ha^(−1),30 kg ha^(−1),60 kg ha^(−1) and 90 kg ha^(−1) to a Typic Paleustalf Alfisol.Soil samples from two depths(0-10 and 10-20 cm)were collected to determine microbial biomass C(MBC),N(MBN),P(MBP),MBC/N ratio,MBC/P ratio,soil CO_(2) flux,microbial qCO_(2),cultivable bacterial and fungal abundance.Biochar and N fertilizer combination effects on MBC,MBN and MBP pools were dependent on biochar doses,N fertilizer rates and soil depth.MBC/N and MBC/P ratios were decreased after 2 years.Soil CO_(2) flux was maximum at post-seeding stage of rice plant,while decreasing trends occurred at active tillering and harvest stage.Increasing doses of biochar irrespective of its combination with N fertilizer rates decreased CO_(2) flux and microbial qCO_(2).Combinations of biochar and N fertilizer increased fungal/bacterial ratio and induced a shift to a more fungal-dominated population after 2 years.Our results sug-gest that combination of biochar doses(3-12 t ha^(−1))with N fertilizer rates had stimulatory effects on microbial biomass pools and activity with positive implications for organic carbon accumulation,nitrogen(N)and phosphorus(P)retention in tropical soils.Segun Oladele Adebayo Adeyemo Ajoke Adegaiye Moses Awodun 2019Biochar2019,1,2:6
3Larvicidal efficacies and chemical composition of essential oils of Pinus sylvestris and Syzygium aromaticum against mosquitoes显示文摘Objective:To assess the chemical composition and mosquito larvicidal potentials of essential oils of locally sourced Pinus sylvestris(P.sylvestris)and Syzygium aromatkum(S.aromaticum)against Aedes aegypti(A.aegypti)and Culex quinquefasciatus(C.quinquefasciatus).Method:The chemical composition of the essential oils of both plants was determined using GCMS while the larvicidal bioassay was carried out using different concentrations of the oils against the larvae of A.aegypti and C.quinquefasciatus in accordance with the standard protocol.Results:The results as determined by GC-MS showed that oil of S.aromaticum has eugenol(80.5%)as its principal constituent while P.sylvestris has 3-Cyclohexene-1-methanol,.alpha.,.alpha.4-trimethyl(27.1%)as its dominant constituent.Both oils achieved over 85%larval mortality within24 h.The larvae of A.aegypti were more susceptible to the oils[LC_(50)(S.aromaticum)=92.56 mg/L,LC_(50)(P.sylvestris)=100.39 mg/L]than C.quinquefasciatus[LC_(50)(S.aromaticum)=124.42 mg/L;LC_(50)(P.sylvestris)=128.00 mg/L].S.aromaticum oil was more toxic to the mosquito larvae than oil of P.sylvatris but the difference in lethal concentrations was insignificant(P>0.05).Condusioii:The results justify the larvicidal potentials of both essential oils and the need to incorporate them in vector management and control.Kehinde Adenike Fayemiwo Monsuru Adebayo Adeleke Ovie Princewill Okoro Shola Hezekiah Awojide Ilias Olufemi Awoniyi 2014Asian Pacific Journal of Tropical Biomedicine2014,4,1:4
4Blast-induced ground vibration prediction in granite quarries:An application of gene expression programming,ANFIS,and sine cosine algorithm optimized ANN显示文摘Blasting of rocks has intrinsic environmental impacts such as ground vibration,which can interfere with the safety of lives and property.Hence,accurate prediction of the environmental impacts of blasting is imperative as the empirical models are not accurate as evident in the literature.Therefore,there is need to consider some robust predictive models for accurate prediction results.Gene expression programming(GEP),adaptive neuro-fuzzy inference system(ANFIS),and sine cosine algorithm optimized artificial neural network(SCA-ANN)models are proposed for predicting the blast-initiated ground vibration in five granite quarries.The input parameters into the models are the distance from the point of blasting to the point of measurement(D),the weight of charge per delay(W),rock density(q),and the Schmidt rebound hardness(SRH)value while peak particle velocity(PPV)is the targeted output.100 datasets were used in developing the proposed models.The performance of the proposed models was examined using the coefficient of determination(R2)and error analysis.The R2 values obtained for the GEP,ANFIS,and SCA-ANN models are 0.989,0.997,and 0.999,respectively,while their errors are close to zero.The proposed models are compared with an empirical model and are found to outperform the empirical model.Abiodun Ismail Lawal Sangki Kwon Olaide Sakiru Hammed Musa Adebayo Idris 2021International Journal of Mining Science and Technology2021,31,2:3
5First isolation of glutinol and a bioactive fraction with good antiinflammatory activity from n-hexane fraction of Peltophorum africanum leaf显示文摘Objective: To investigate the anti-inflammatory activity of different fractions and glutinol(isolated compound),using nitric oxide synthase and cyclooxygenase(COX) inhibition as an indication of anti-inflammatory activity,Methods: Anti-inflammatory activity was evaluated using an in vitro assay determining the inhibition of the activity of pro-inflammatory enzyme model,Cyclooxygenases and inducible nitric oxide synthase are crucial enzymes involved in the pathogenesis of many chronic inflammatory conditions,Results: Sub-fraction F3.3 that was derived from n-hexane fraction of PA leaves significantly inhibited(P = 0.01) the catalytic activity of COX-2(IC50 = 0.67 μg/m L) better than isolated compound,glutinol(IC50 = 1.22 μg/m L),compound 2(CP2)(IC50 = 1.71 μg/m L) and sub-fraction F3.3.0(IC50 = 1.30 μg/m L),A similar trend was observed in investigation of the inhibition of nitric oxide synthesis in RAW 264.7 cells by F3.3,glutinol,CP2 and F3.3.0,Inducible COX-2 and inducible nitric oxide synthase are among potent signalling enzymes that exacerbate inflammation,Conclusions: Bioactive sub-fractions(F3.3 and F3.3.0) derived from the n-hexane fraction of PA had good anti-inflammatory activity,and the isolated compound,and glutinol may be useful as a template for the development of new anti-inflammatory drugs.Salmon A Adebayo Leshweni J Shai Jacobus N Eloff 2017Asian Pacific Journal of Tropical Medicine2017,10,1:2

15Discontinuities effect on drilling condition and performance of selected rocks in Nigeria显示文摘The study examined joint discontinuity spacing effect on drilling condition and performance in selected rocks in Ilorin and Ibese areas, Nigeria. Five samples for each rock type(gneiss and limestone) were tested in the laboratory for chemical, physical and mechanical properties. Dip direction and joint spacing were measured using compass clinometers. The chemical composition was determined using X-ray Fluorescence(XRF) spectrometer. The results show that gneiss has SiO2 of 61.88% and limestone has CaO content of 52.3%. The average dry density of gneiss and limestone are 2.6 and 2.39 g/cm3, respectively. The uniaxial compressive strength of gneiss and limestone are 195 and 93.83 MPa, respectively. These rocks are classified as strong and moderately strong rock. Gneiss and limestone have mean joint discontinuity spacing of 0.79 and 0.25 m, which classified them as moderate and wide joint spacing respectively. Joint spacing was correlated with specific energy, bit wear and uniaxial compressive using Statistical Package for Social Science(SPSS). The regression model has multiple coefficient of correlation of R2= 0.791 and R2= 0.995 for gneiss and limestone, respectively. The variation in joint spacing could be attributed to specific energy, bit wear and uniaxial compressive strength which affect drilling condition and performance.Ultimately, as joint spacing gets closer, the drilling velocity increases, drill string will be stable.Adebayo Babatunde Bello Wasiu Ademola 2014International Journal of Mining Science and Technology2014,24,5:1
