| 1 | Waste production in aquaculture:Sources,components and managements in different culture systems显示文摘The intensification of aquaculture has emerged as a viable alternative for increasing aquaculture production due to competition that arose from the use of natural resources,such as land and water,by other production and developmental sectors.However,intensification demands increased inputs,such as fish and feed per unit culture area and,therefore,increased waste generation from the aquaculture production systems.The impact of waste products from aquaculture has increased public concern and threatens the sustainability of aquaculture practices.The need for increasing the production of aquaculture products cannot be overemphasized and,therefore,there is a need to develop culture systems that will increase fish production with efficient waste management in order to limit environmental degradation resulting from aquaculture wastes and ensure its sustainability.This paper reviewed various aspects of waste production from aquaculture,their sources,components,and methods of management,in different culture systems,primarily discussing waste production from feed,chemicals,and pathogens.We aimed to establish the sources of wastes,their contents,and potential harms to both the fish culture and the environment.Suggestions for managing wastes in different culture systems were made to ensure an improved and sustainable aquaculture production. | Akeem Babatunde Dauda Abdullateef Ajadi Adenike Susan Tola-Fabunmi Ayoola Olusegun Akinwole | 2019 | Aquaculture and Fisheries2019，4，3： | 19 |
| 2 | Sediment records of environmental changes in the south end of the Zhejiang-Fujian coastal mud area during the past 100 years显示文摘Previous studies carried out in the East China Sea(ECS) mud area focused on long-term environmental changes in sedimentary records during the Holocene, especially during the mid-Holocene high-stand water levels period. These results indicate that sensitive grain size groups can be used as a sedimentary proxy to reconstruct the evolution of the East Asian Winter Monsoon(EAWM). The studies have been carried out mainly in the northern and middle portions of the Zhejiang-Fujian coastal mud, however, similar research in the southern portion and the comparison between sedimentary proxy and modern measured data of EAWM are lacking. In this paper, we focused on a sedimentary record of the past 100 years with an enhanced resolution of 1.8 years. Investigations of the southern end of the Zhejiang-Fujian coastal mud area were conducted on the basis of 210 Pb chronology, grain-size analysis and chemical element analysis. The correspondence between the mean grain size(Mz) of sediment sensitive grain size and the measured EAWM was confirmed for the first time. We found that during the recent 100 years, the variation of the mean grain size of the sensitive population in the southern portion of the Zhejiang-Fujian mud was mainly controlled by the EAWM intensity changes; and not directly related to changes in the sediment discharge from Datong station of the Changjiang River(DTSD). Finally, recent changes in the content of heavy metals in study area refl ect the impact of human activities on the environment. | 王琳淼 李广雪 高飞 刘玲 刘勇 DADA Olusegun A | 2014 | Chinese Journal of Oceanology and Limnology2014，32，4： | 5 |
| 3 | A geomorphological response of beaches to Typhoon Meari in the eastern Shandong Peninsula in China显示文摘Eight representative beach profiles on the eastern coast of the Shandong Peninsula are observed and measured in2011 and 2012 to determine the coastal processes under the lower tropical wind speed condition and the beach response to and recovery from the tropical storm Meari in a rare typhoon region. The results show that it is the enhancement and directional change of cross-shore and longshore sediment transports caused by Meari that leads to the beach morphological changes, and most of the sediment transports occur during the pre-Meari landing phase. The erosional scarp formation and the berm or beach face erosion are the main geomorphological responses of the beaches to the storm. The storm characteristics are more important than the beach shapes in the storm response process of the beaches on Shandong Peninsula. The typhoon is a fortuitous strong dynamic event,and the effect on the dissipative beach is more obvious than it is on the reflective beach in the study region.Furthermore, the beach trend is the main factor that controlls the storm effect intensity, and it is also closely related to the recovery of the beach profiles. | DING Dong YANG Jichao LI Guangxue DADA Olusegun A GONG Lixin WANG Nan WANG Xiangdong ZHANG Bin | 2015 | Acta Oceanologica Sinica2015，34，9： | 4 |
| 4 | 近60年来南黄海沉积物高分辨率敏感粒级对东亚冬季风的响应显示文摘对南黄海中部泥质区F306柱状样的沉积物进行分析,运用粒径—标准偏差法,得出该孔敏感粒级组分为23.10~65.30μm(5.44Φ~3.94Φ),其粒级的含量15.6%~22.3%,平均粒径38.5~41.4μm(4.70Φ~4.59Φ),证明敏感粒级可以作为东亚冬季风的高分辨率替代指标,进一步阐明了敏感粒级作为东亚冬季风替代指标在更高分辨率上的可行性。根据敏感粒级沉积记录,在1950—1986年期间,将东亚冬季风分为强—弱—强3个阶段,指示了该阶段东亚冬季风存在近10年的周期。1986/1987为近60多年来东亚冬季风由强变弱的转折点,与东亚气候变化具有较好的对应关系,首次在中国东部海域中记录了此逆转事件,认为1986年后沉积物敏感粒级的变粗可能与长江物源变粗、东亚冬季风的减弱以及夏季风增强有关。 | 高星华 李广雪 张海啟 Dada Olusegun A 刘世东 陈中亚 李亨健 王琳淼 刘玲 | 2016 | 海洋地质前沿2016，32，8： | 3 |
| 5 | The Marine Dynamics and Changing Trend off the Modern Yellow River Mouth显示文摘Topography around the Yellow River mouth has changed greatly in recent years, but studies on the current state of ma- rine dynamics off the Yellow River mouth are relatively scarce. This paper uses a two-dimension numerical model(MIKE 21) to reveal the tidal and wave dynamics in 2012, and conducts comparative analysis of the changes from 1996 to 2012. The results show that M2 amphidromic point moved southeastward by 11 km. It further reveals that the tides around the Yellow River mouth are relatively stable due to the small variations in the tidal constituents. Over the study period, there is no noticeable change in the distribution of tidal types and tidal range, and the mean tidal range off the river mouth during the period studied is 0.5–1.1 m. However, the tidal currents changed greatly due to large change in topography. It is observed that the area with strong tidal currents shifted from the old river mouth(1976–1996) to the modern river mouth(1996–present). While the tidal current speeds decreased continually off the old river mouth, they increased off the modern river mouth. The Maximum Tidal Current Speed(MTCS) reached 1.4 m s-1, and the maximum current speed of 50-year return period reached 2.8 m s-1. Waves also changed greatly due to change in topography. The significant wave height(H1/3) of 50-year return period changed proportionately with the water depth, and the ratio of H1/3 to depth being 0.4–0.6. H1/3 of the 50-year return period in erosion zone increased continually with increasing water depth, and the rate of change varied between 0.06 and 0.07 m yr-1. Based on the results of this study, we infer that in the future, the modern river mouth will protrude gradually northward, while the erosion zone, comprising the old river mouth and area between the modern river mouth and the old river mouth(Intermediate region) will continue to erode. As the modern river mouth protrudes towards the sea, there will be a gradual increase in the current speed and decrease in wave height. Conversely, the old river mouth will retreat, with gradual decrease in current speed and increase in wave height. As more coastal constructions spring up around the Yellow River mouth in the future, we recommend that variation in hydrodynamics over time should be taken into consideration when designing such coastal constructions. | WANG Nan LI Guangxue XU Jishang QIAO Lulu DADA Olusegun A.

| 6 | Assessment of traffic performance measures and safety based on driver age and experience:A microsimulation based analysis for an unsignalized T-intersection显示文摘Traffic safety and performance measures such as crash risk and queue lengths or travel times are influenced by several important factors including those related to environment,human,and roadway design,especially at intersections.Previous research has studied different aspects related to these factors,yet these characteristics are not fully investigated with a focus on age and experience of drivers.In this paper,we investigate this issue by using a two-phase approach via a case study application on a critical T-intersection in the City of Tallahassee,Florida.The first phase includes a scenario-based microsimulation analysis through the use of a microscopic simulation software,namely VISSIM,to illustrate the variations in traffic performance measures with respect to driver compositions of different age groups in the traffic stream.A variety of scenarios is created where the driving characteristics are provided as inputs to these scenarios in terms of decision making and risk taking.This is also supported by a sensitivity analysis conducted based on the driver composition in the traffic.The second phase includes the analysis of microsimulation outputs via a tool developed by Federal Highway Administration tool,namely the Surrogate Safety Assessment Model(SSAM),in order to determine the traffic conflicts that occur in each scenario.These conflicts are also compared with real-life crash data for validation purposes.Results show that(a) the differences in risk perception that affect driving behavior might be significant in influencing traffic safety and performance measures,and(b) the proposed approach is considerably successful in simulating the actual crash conflict points. | Mehmet Baran Ulak Eren Erman Ozguven Ren Moses Thobias Sando Walter Boot Yassir AbdelRazig John Olusegun Sobanjo | 2019 | Journal of Traffic and Transportation Engineering(English Edition)2019，6，5： | 2 |

| 9 | Review of the malaria epidemiology and trends in Zambia显示文摘A comprehensive desk review of malaria trends was conducted between 2000-2010 in Zambia to study malaria epidemiology and trends to guide strategies and approaches for effective malaria control.This review considered data from the National Health Information Management System,Malaria Surveys and Programme Review reports and analyzed malaria in-patient cases and deaths in relation to intervention coverage for all ages.Data showed three distinct epidemiological strata after a notable malaria reduction(66%)in in-patient cases and deaths,particularly between 2000-2008.These changes occurred following the(re-)introduction and expansion of indoor residual spraying up to 90%coverage,scale-up of coverage of long-lasting insecticidetreated nets in household from 50%to 70%,and artemisin-based combination therapy nationwide.However,malaria cases and deaths re-surged,increasing in 2009-2010 in the northern-eastern parts of Zambia.Delays in the disbursement of funds affected the implementation of interventions,which resulted in resurgence of cases and deaths.In spite of a decline in malaria disease burden over the past decade in Zambia,a reversal in impact is notable in the year 2009-2010,signifying that control gains are fragile and must be sustained toeliminate malaria. | Freddie Masaninga Emmanuel Chanda Pascalina Chanda-Kapata Busiku Hamainza Hieronymo T Masendu Mulakwa Kamuliwo Wambinji Kapelwa John Chimumbwa John Govere Mac Otten Ibrahima Soce Fall Olusegun Babaniyi | 2013 | Asian Pacific Journal of Tropical Biomedicine2013，3，2： | 2 |
| 10 | Antimalarial potential of kolaviron,a biflavonoid from Garcinia kola seeds,against Plasmodium berghei infection in Swiss albino mice显示文摘Objective:To investigate the antimalarial potential of kolaviron(KV),a biflavonoid fraction from Garcinia kola seeds,against Plasmodium berghei(P.berghei)infection in Swiss albino mice.Methods:The study consists of seven groups of ten mice each.Groups I,II and III were normal mice that received com oil.KV1 and chloroquine(CQ),respectively.Groups IV,V,ⅥandⅦwere infected mice that received corn oil.CQ,KYI and KV2.respectively.CQ.KY1 and KV2were given at 10-,100-and 200-mg/kg daily,respectively for three consecutive days.Results:Administration of KV1 and KV2 significantly(P<0.05)suppressed P.berghei-infection in the mice by 85%and 90%.respectively,while CQ produced 87%suppression relative to untreated infected group after the fifth day of treatment.Also,KV2 significantly(P<0.05)increased the mean survival time of the infected mice by 175%.The biflavonoid prevented a drastic reduction in HCV from day4 of treatment,indicating its efficacy in ameliorating anaemia.Significant(P<0.05)oxidative stress assessed by the elevation of serum and hepatic malondialdehydewere observed in unlrealed P.berghei-infected mice.Specifically,senum and hepatic malondialdehyde levels increased by93%and 78%,resjiectively in the unlrealed infecled mice.Furlhennore,antioxidant indices,viz;superoxide dismutase.catalase,glutathione-s-transferasc.glualhione peroxidase and reduced gluathione decreased significantly(P<0.05)in the tissues of untreated P.berghei-infected mice.KV significantly(P<0.05)ameliorated the P.berghei-induced decrease in antioxidant status of the infected mice.Conclusions:This study shows that kolaviron,especially at 200 mg/kg,has high antimalarial activities in P.berghei-infected mice,in addition to its known antioxidant properties. | Adaramoyc Oluwatosin Akinpelu Tolulope Kosoko Ayokulchin Okoric Patricia Kehinde Aderemi Falade Catherine Ademowo Olusegun | 2014 | Asian Pacific Journal of Tropical Medicine2014，7，2： | 2 |
