1A novel artificial intelligent model for predicting air overpressure using brain inspired emotional neural network显示文摘Blasting is the live wire of mining and its operations,with air overpressure(AOp)recognised as an end product of blasting.AOp is known to be one of the most important environmental hazards of mining.Further research in this area of mining is required to help improve on safety of the working environment.Review of previous studies has shown that many empirical and artificial intelligence(AI)methods have been proposed as a forecasting model.As an alternative to the previous methods,this study proposes a new class of advanced artificial neural network known as brain inspired emotional neural network(BIENN)to predict AOp.The proposed BI-ENN approach is compared with two classical AOp predictors(generalised predictor and McKenzie formula)and three established AI methods of backpropagation neural network(BPNN),group method of data handling(GMDH),and support vector machine(SVM).From the analysis of the results,BI-ENN is the best by achieving the least RMSE,MAPE,NRMSE and highest R,VAF and PI values of 1.0941,0.8339%,0.1243%,0.8249,68.0512%and 1.2367 respectively and thus can be used for monitoring and controlling AOp.Victor Amoako Temeng Yao Yevenyo Ziggah Clement Kweku Arthur 2020International Journal of Mining Science and Technology2020,30,5:8

11Elevated atmospheric CO_(2) impact on carbon and nitrogen transformations and microbial community in replicated wetland显示文摘Background:Elevated atmospheric CO_(2) has direct and indirect influences on ecosystem processes.The impact of elevated atmospheric CO_(2) concentration on carbon and nitrogen transformations,together with the microbial community,was evaluated with water hyacinth(Eichhornia crassipes)in an open-top chamber replicated wetland.The responses of nitrogen and carbon pools in water and wetland soil,and microbial community abundance were studied under ambient CO_(2) and elevated CO_(2)(ambient+200μL L^(−1)).Results:Total biomass for the whole plant under elevated CO_(2) increased by an average of 8%(p=0.022).Wetlands,with water hyacinth,showed a significant increase in total carbon and total organic carbon in water by 7%(p=0.001)and 21%(p=0.001),respectively,under elevated CO_(2) compared to that of ambient CO_(2).Increase in dissolved carbon in water correlates with the presence of wetland plants since the water hyacinth can directly exchange CO_(2) from the atmosphere to water by the upper epidermis of leaves.Also,the enrichment CO_(2) showed an increase in total carbon and total organic carbon concentration in wetland soil by 3%(p=0.344)and 6%(p=0.008),respectively.The total nitrogen content in water increased by 26%(p=0.0001),while total nitrogen in wetland soil pool under CO_(2) enrichment decreased by 9%(p=0.011)due to increased soil microbial community abundance,extracted by phospholipid fatty acids,which was 25%larger in amount than that of the ambient treatment.Conclusion:The study revealed that the elevated CO_(2) would affect the carbon and nitrogen transformations in wetland plant,water,and soil pool and increase soil microbial community abundance.Dawei Jiang Lifei Chen Nan Xia Eyram Norgbey Desmond Ato Koomson Williams Kweku Darkwah 2020Ecological Processes2020,9,1:1

15First molecular identification of multiple tick‑borne pathogens in livestock within Kassena‑Nankana,Ghana显示文摘The risk of pathogen transmission continues to increase significantly in the presence of tick vectors due to the trade of livestock across countries.In Ghana,there is a lack of data on the incidence of tick-borne pathogens that are of zoonotic and veterinary importance.This study,therefore,aimed to determine the prevalence of such pathogens in livestock using molecular approaches.A total of 276 dry blood spots were collected from cattle(100),sheep(95)and goats(81)in the Kassena-Nankana Districts.The samples were analyzed using Polymerase Chain Reaction(qPCR)and conventional assays and Sanger sequencing that targeted pathogens including Rickettsia,Coxiella,Babesia,Theileria,Ehrlichia and Anaplasma.An overall prevalence of 36.96%was recorded from the livestock DBS,with mixed infections seen in 7.97%samples.Furthermore,the prevalence of infections in livestock was recorded to be 19.21%in sheep,14.13%in cattle,and 3.62%in goats.The pathogens identified were Rickettsia spp.(3.26%),Babesia sp.Lintan(8.70%),Theileria orientalis(2.17%),Theileria parva(0.36%),Anaplasma capra(18.48%),Anaplasma phagocytophilum(1.81%),Anaplasma marginale(3.26%)and Anaplasma ovis(7.25%).This study reports the first molecular identification of the above-mentioned pathogens in livestock in Ghana and highlights the use of dry blood spots in resource-limited settings.In addition,this research provides an update on tick-borne pathogens in Ghana,suggesting risks to livestock production and human health.Further studies will be essential to establish the distribution and epidemiology of these pathogens in Ghana.Seth Offei Addo Ronald Essah Bentil Kevin Nii Yartey Jane Ansah‑Owusu Eric Behene Selassie Bruku Victor Asoala Suzanne Mate John Asiedu Larbi Philip Kweku Baidoo Michael David Wilson Joseph W.Diclaro II Samuel K.Dadzie 2023Animal Diseases2023,3,1:0

17Potential factors influencing lymphatic filariasis transmission in'hotspot'and'control'areas in Ghana:the importance of vectors显示文摘Background:Mass drug administration(MDA)programmes for the control of lymphatic filariasis in Ghana,have been ongoing in some endemic districts for 16 years.The current study aimed to assess factors that govern the success of MDA programmes for breaking transmission of lymphatic filariasis in Ghana.Methods:The study was undertaken in two'hotspot'districts(Ahanta West and Kassena Nankana West)and two control districts(Mpohor and Bongo)in Ghana.Mosquitoes were collected and identified using morphological and molecular tools.A proportion of the cibarial armatures of each species was examined.Dissections were performed onAnopheles gambiae for filarial worm detection.A questionnaire was administered to obtain information on MDA compliance and vector control activities.Data were compared between districts to determine factors that might explain persistent transmission of lymphatic filariasis.Results:High numbers of mosquitoes were sampled in Ahanta West district compared to Mpohor district(F=16.09,P=0.002).There was no significant difference between the numbers of mosquitoes collected in Kassena Nankana West and Bongo districts(F=2.16,P=0.185).Mansonia species were predominant in Ahanta West district.An.coluzzii mosquitoes were prevalent in all districts.An.melas with infected and infective filarial worms was found only in Ahanta West district.No differences were found in cibarial teeth numbers and shape for mosquito species in the surveyed districts.Reported MDA coverage was high in all districts.The average use of bednet and indoor residual spraying was 82.4 and 66.2%,respectively.There was high compliance in the five preceding MDA rounds in Ahanta West and Kassena Nankana West districts,both considered hotspots of lymphatic filariasis transmission.Conclusions:The study on persistent transmission of lymphatic filariasis in the two areas in Ghana present information that shows the importance of local understanding of factors affecting control and elimination of lymphatic filariasis.Unlike Kassena Nankana West district where transmission dynamics could be explained by initial infection prevalence and low vector densities,ongoing lymphatic filariasis transmission in Ahanta West district might be explained by high biting rates ofAn.gambiae and initial infection prevalence,coupled with high densities ofAn.melas andMansonia vector species that have low or no teeth and exhibiting limitation.Sellase Pi-Bansa Joseph Harold Nyarko Osei Kwadwo Kyeremeh Frempong Elizabeth Elhassan Osei Kweku Akuoko David Agyemang Collins Ahorlu Maxwell Alexander Appawu Benjamin Guibehi Koudou Michael David Wilson Dziedzom Komi de Souza Samuel Kweku Dadzie Jurg Utzinger Daniel Adjei Boakye 2019Infectious Diseases of Poverty2019,8,1:0
