| 1 | An online maximum power point capturing technique for highefficiency power generation of solar photovoltaic systems显示文摘This paper proposes a novel high-efficiency generation technique for photovoltaic(PV) system,named maximum power point capturing(MPPC) technique. This is an aperiodic perturbation MPPC technique compared to the conventional periodic perturbation maximum power point tracking technique. Firstly, under a closed-loop circuit and an open-loop circuit,the complete I-V curves and P-V curves are defined. Secondly, the proposed MPPC technique is based on the complete I-V curves and a practical model of solar PV systems.The proposed method realizes that maximum power point(MPP) is captured online, and its control strategy is designed to set a steady operating area around MPP. The duty cycle keeps constant when the operating point is within the steady operating area, i.e., aperiodic perturbation, and when the operating point is outside the steady operating area, MPPC is triggered to capture a new MPP with an updated steady operating area. Simulation results demonstrate that no oscillations exist in steady-state;dynamic performances are improved;and only two perturbations are required to capture the new MPP. Using the proposed MPPC method,low voltage ride through and high voltage ride through can be prevented. | Lijun ZHANG Samson Shenglong YU Tyrone FERNANDO Herbert Ho-Ching IU Kit Po WONG | 2019 | Journal of Modern Power Systems and Clean Energy2019，7，2： | 8 |

| 3 | Spontaneous combustion liability between coal seams: A thermogravimetric study显示文摘The spontaneous combustion liability of coal can be determined by using different experimental techniques.These techniques are well-known in their application,but no certain test method has become a standard to prove the reliability of all of them.A general characterisation which included proximate and ultimate analyses,petrographic properties and spontaneous combustion tests(thermogravimetric analysis(TGA)and the Wits-Ehac tests)were conducted on fourteen coal and four coal-shale samples.The spontaneous combustion liability of these samples collected between coal seams(above and below)were predicted using the TGA and the Wits-Ehac tests.Six different heating rates(3,6,9,15,20 and 25C/min)were selected based on the deviation coefficient to obtain different derivative slopes and a liability index termed the TGspc index.This study found that coal and coal-shale undergo spontaneous combustion between coal seams when exposed to oxygen in the air.Their intrinsic properties and proneness towards spontaneous combustion differ considerably from one seam to the other.The Wits-Ehac test results agreed with the TGspc results to a certain extent and revealed the incidents of spontaneous combustion in the coal mines. | Moshood Onifade Bekir Genc Samson Bada | 2020 | International Journal of Mining Science and Technology2020，30，5： | 6 |

| 7 | The genetic framework for development of nephrolithiasis显示文摘Over 1%-15% of the population worldwide is affected by nephrolithiasis,which remains the most common and costly disease that urologists manage today.Identification of atrisk individuals remains a theoretical and technological challenge.The search for monogenic causes of stone disease has been largely unfruitful and a technological challenge;however,several candidate genes have been implicated in the development of nephrolithiasis.In this review,we will review current data on the genetic inheritance of stone disease,as well as investigate the evolving role of genetic analysis and counseling in the management of nephrolithiasis. | Vinaya Vasudevan Patrick Samson Arthur D.Smith Zeph Okeke | 2017 | Asian Journal of Urology2017，4，1： | 5 |
| 8 | Electrostatic concentration of phosphate flotation concentrate显示文摘The concentration of phosphate flotation concentrate with P2O5 grade lower than the commercially acceptable phosphate quality was upgraded in the use of tribo-electrostatic technique. The concentration of the flotation concentrate stream was conducted under both triboelectrification and inductive charging mechanism. Mineralogical analysis reveals that the phosphate ore utilized was dominated mainly by fluorapatite, crandallite, wavellite, and with quartz as the major gangue mineral. Flotations concentrate of about 28.87% P2O5 was obtained from the reverse flotation technique, after conditioning the phosphate ore at 80% passing 150 lm under Lilafloat. Constant parameters such as à6 kV charging voltage, 25 kV separating voltage, inlet air, different charger rotary speed and splitter distances were investigated. Commercially accepted grade of 35.50% P2O5 was attained after the second stage of separation with a recovery of 12.26%, another phosphate product of 34.02% P2O5 and 85.19% was also recovered under the same condition. Single stage of separation also shows a significant increase in the grade of the product obtained, with 33.41% P2O5 and 84.07% recovery achievable. The practicability of tribo-electrostatic separation technique for upgrading flotation concentrates resulted in a significant increase in grade for <150 lm product that do not meet the viable grade. | Bada Samson Gcanga Sandi Falcon Lionel Falcon Rosemary Makhula Mpho | 2013 | International Journal of Mining Science and Technology2013，23，3： | 4 |
| 9 | Prokineticin 2/Bv8 is expressed in Kupffer cells in liver and is down regulated in human hepatocellular carcinoma显示文摘AIM: To study the implication of prokineticin 1 (PK1/EG- VEGF) and prokineticin 2 (PK2/Bv8) in hepatocellular carcinoma angiogenesis. METHODS: The gene induction of PK1/EG-VEGF and PK2/Bv8 was investigated in 10 normal, 28 fibrotic and 28 tumoral livers by using real time PCR. Their expression was compared to the expression of VEGF (an angiogenesis marker), vWF (an endothelial cell marker) and to CD68 (a monocyte/macrophage marker). Furthermore, the mRNA levels of PK1/EG-VEGF, PK2/Bv8, prokineticin receptor 1 and 2 were evaluated by real time PCR in isolated liver cell populations. Finally, PK2/Bv8 protein was detected in normal liver paraffin sections and in isolated liver cells by immunohistochemistry and immunocytochemistry. RESULTS: PK2/Bv8 mRNA but not PK1/EG-VEGF was expressed in all types of normal liver samples examined. In the context of liver tumor development, we reported that PK2/Bv8 correlates only with CD68 and showed a significant decrease in expression as the pathology evolves towards cancer. Whereas, VEGF and vWF mRNA were significantly upregulated in both fibrosis and HCC,as expected. In addition, out of all isolated liver cells examined, only Kupffer cells (liver resident macrophages) express significant levels of PK2/Bv8 and its receptors, prokineticin receptor 1 and 2. CONCLUSION: In normal liver PK2/Bv8 and its receptors were specifically expressed by Kupffer cells. PK2/Bv8 expression decreased as the liver evolves towards cancer and did not correlate with HCC angiogenesis. | Justin Monnier Claire Piquet-Pellorce Jean-Jacques Feige Orlando Musso Bruno Clément Bruno Turlin Nathalie Théret Michel Samson | 2008 | World Journal of Gastroenterology2008，14，8： | 4 |
| 10 | Diversity and distribution patterns of non-volant smallmammals along different elevation gradients on Mt. Kenya,Kenya显示文摘The distribution of small mammals in mountainous environments across different elevations can provide important information on the effects of climate change on the dispersal of species. However, few studies conducted on Afromontane ecosystems have compared the altitudinal patterns of small mammal diversity. We investigated the species diversity and abundance of non-volant small mammals(hereafter ‘small mammals')on Mt. Kenya, the second tallest mountain in Africa,using a standard sampling scheme. Nine sampling transects were established at intervals of 200 m on the eastern(Chogoria) and western(Sirimon) slopes.A total of 1 905 individuals representing 25 species of small mammals were trapped after 12 240 trap-nights.Abundance was highest at mid-elevations on both slopes.However, species richness and their distribution patterns differed between the two slopes. More species were recorded on Chogoria(24) than on Sirimon(17). On Chogoria, species richness was higher at mid-high elevations, with a peak at mid-elevation(2 800 m a.s.l.),whereas species richness showed little variation on the Sirimon slope. These results indicate that patterns of species diversity can differ between slopes on the same mountain. In addition, we extensively reviewed literature on Mt. Kenya's mammals and compiled a comprehensive checklist of 76 mammalian species. However, additional research is required to improve our understanding of smal mammal diversity in mountain habitats in Africa. | Simon Musila Zhong-Zheng Chen Quan Li Richard Yego Bin Zhang Kenneth Onditi Immaculate Muthoni Shui-Wang He Samson Omondi James Mathenge Esther N.Kioko Xue-Long Jiang | 2019 | Zoological Research2019，40，1： | 4 |

| 19 | Urea transport and hydrolysis in the rumen: A review显示文摘Inefficient dietary nitrogen(N)conversion to microbial proteins,and the subsequent use by ruminants,is a major research focus across different fields.Excess bacterial ammonia(NH3)produced due to degradation or hydrolyses of N containing compounds,such as urea,leads to an inefficiency in a host’s ability to utilize nitrogen.Urea is a non-protein N containing compound used by ruminants as an ammonia source,obtained from feed and endogenous sources.It is hydrolyzed by ureases from rumen bacteria to produce NH_(3) which is used for microbial protein synthesis.However,lack of information exists regarding urea hydrolysis in ruminal bacteria,and how urea gets to hydrolysis sites.Therefore,this review describes research on sites of urea hydrolysis,urea transport routes towards these sites,the role and structure of urea transporters in rumen epithelium and bacteria,the composition of ruminal ureolytic bacteria,mechanisms behind urea hydrolysis by bacterial ureases,and factors influencing urea hydrolysis.This review explores the current knowledge on the structure and physiological role of urea transport and ureolytic bacteria,for the regulation of urea hydrolysis and recycling in ruminants.Lastly,underlying mechanisms of urea transportation in rumen bacteria and their physiological importance are currently unknown,and therefore future research should be directed to this subject. | Samson Hailemariam Shengguo Zhao Yue He Jiaqi Wang | 2021 | Animal Nutrition2021，，4： | 3 |
| 20 | Schistosomiasis in Zambia:a systematic review of past and present experiences显示文摘Background:The speedy rate of change in the environmental and socio-economics factors may increase the incidence,prevalence and risk of schistosomiasis infections in Zambia.However,available information does not provide a comprehensive understanding of the biogeography and distribution of the disease,ecology and population dynamics of intermediate host snails.The current study used an information-theoretical approach to understand the biogeography and prevalence schistosomiasis and identified knowledge gaps that would be useful to improve policy towards surveillance and eradication of intermediate hosts snails in Zambia.Methods:To summarise the existing knowledge and build on past and present experiences of schistosomiasis epidemiology for effective disease control in Zambia,a systematic search of literature for the period 2000-2017 was done on PubMed,Google Scholar and EBSCOhost.Using the key words:‘Schistosomiasis’,‘Biomphalaria’,‘Bulinus’,‘Schistosoma mansoni’,‘Schistosoma haematobium’,and‘Zambia’,in combination with Booleans terms‘AND’and‘OR’,published reports/papers were obtained and reviewed independently for inclusion.Results:Thirteen papers published in English that fulfilled the inclusion criteria were selected for the final review.The papers suggest that the risk of infection has increased over the years and this has been attributed to environmental,socio-economic and demographic factors.Furthermore,schistosomiasis is endemic in many parts of the country with infection due to Schistosoma haematobium being more prevalent than that due to S.mansoni.This review also found that S.haematobium was linked to genital lesions,thus increasing risks of contracting other diseases such as HIV and cervical cancer.Conclusions:For both S.haematobium and S.mansoni,environmental,socio-economic,and demographic factors were influential in the transmission and prevalence of the disease and highlight the need for detailed knowledge on ecological modelling and mapping the distribution of the disease and intermediate host snails for effective implementation of control strategies. | Chester Kalinda Moses J.Chimbari Samson Mukaratirwa | 2018 | Infectious Diseases of Poverty2018，7，1： | 3 |
