Background: Urological care has been advancing quickly over the last ten years in Benin. In order to conveniently support that trend towards better urological care standards, decision-makers need sound data on urological diseases in the country. Objective: To determine the prevalence of urological diseases in the former Military Teaching Hospital of Cotonou. Patients and Method: We retrospectively collected the urological diseases that the institution had managed from January 2012 to December 2020. We used Excel<sup>©</sup> 2010 and SPSS<sup>©</sup> to analyze the collected data. Results: 4244 patients, i.e. 3717 males (87.58%) and 527 females (12.42%) were managed during the study period. The main diseases diagnosed were benign prostatic hyperplasia (32.61%, n = 1384), erectile dysfunction (10.44%, n = 443), chronic prostatitis (5.94%, n = 252), prostate cancer (4.03%, n = 171), and ejaculatory disorders (3.44%, n = 146). In patients ≤ 15 years, predominant diseases were peritoneal vaginal canal (15.9%, n = 43), circumcision (15.6%, n = 42), testicular dystopia (10.7%, n = 29), hydrocele (7.8%, n = 21), and hypospadias (5.6%, n = 15). Wilms tumor (1.9%, n = 5) was the first cancer, testicular (0.4%, n = 1) and para-testicular (0.4%, n = 1) tumors were the next. In patients > 15 and ≤40 years, the main diseases were infertility (14.1%, n = 189), chronic prostatitis (12.9%, n = 173), erectile dysfunction (10.1%, n = 135), ejaculatory disorders (6.2%, n = 83), genital infections (6.2%, n = 83) and urinary stone (4.9%, n = 66). The first cancer was kidney cancer (0.97%, n = 13) followed by bladder cancer (0.3%, n = 4) and testicular tumor (0.3%, n = 4). In patients >40 years, the most prevalent diseases were BPH (52.0%, n = 1370), erectile dysfunction (11.7%, n = 308), prostate cancer (6.5%, n = 171), inguinal hernia (5.1%, n = 134), and urinary stone (3.9%, n = 102). Prostate cancer is the first cancer;the next were bladder (0.95%, n = 25) and kidney (0.68%, n = 18) cancers. Conclusion: Benign prostatic hyperplasia and urological cancers (prostate, bladder and kidney cancers) were the main urological diseases at the former Military Teaching Hospital of Cotonou. Urological malformations and Wilms tumor were the main diseases in the children. 展开更多

The paper has analyzed decorative characteristics and architectural style of Leichang Former Residence which have been summarized as precise axial space sequence that can be divided into dragon gate, central room and drawing room. It has explained the spatial-temporal view of "the unity between heaven and human" and human's subjective ideological connotation in Leichang Former Residence. From the perspectives of the spiritual connotation of roof decorations, grading system of roofing tiles and manifestation form, it has deeply revealed the important expressive force and representativeness of roofs in architectural group, pointed out its aesthetic feature and spiritual restriction to architectures even human's behavior, and showed that the roof is the architectural factor directly manifesting "rituality" and "the unity between human and heaven" in Chinese traditional culture. 展开更多

Objective:To investigate the adhesion potential and cell surface properties against enteric pathogens Salmonella typhi.Salmonella para typhi A and Vibrio cholera.Methods:Adhesion potentials of spore and vegetative phase were studied separately for the isolates.Hydrophobic nature was measured on the basis of affinity towards the xylene.Autoaggregalion and coaggregation were studied on the basis of clumping of cells.In vitro adhesion studies were done on mucous which were prepared from infant child faeces.Biofilm production of superior adhesive isolate was confirmed by SEM analysis.Results:Spore and vegetative phases of isolates possessed a different rate of adhesion potentials on intestinal mucous,which indicated that cell surface properties were involved in adhesion process.Spores showed a higher hydrophobicity than their vegetative cells which remained less or non hydrophobic.Vegetative phases showed capabilities for autoaggregation and coaggregation.Spores were found to be more adhesive on intestinal mucous than vegetative phase.Among enteric pathogens Vibrio cholera registered higher adhesion potentials with supporting cell surface properties.Among the five sporeforming isolates,isolate BM-3 possess superior adhesion than enteric pathogens and also exhibited biofilm formation which enhances colonization potential.Conclusions:Spore and vegetative cell phases shows differences in adhesion potentials.Cell surface properties and adhesion studies reveals that isolate BM-3 can be selected as superior isolate which is capable for biofilm production.In short,isolate BM-3 possesses an enhanced adhesion potential than enteric pathogens towards intestinal mucous which is a desirable probiotic character. 展开更多

In recent years, the disorder of rural space, the gradual decline and extinction of traditional culture, the destruction of natural environment, the excessive consumption of natural resources and so on all lead to the increasingly backward problem of rural human settlements. Under this background, people also gradually turn their attention to the renovation and planning of rural human settlements. Based on practical investigation, this study analyzed the importance of village renovation planning and summarized the basic principles of village renovation planning. Based on the theory of The Sciences of Human Settlements, applying rigorous comprehensive research methods, it put forward the main contents of village renovation planning: land use planning, economic and industrial planning, comprehensive renovation of residential environment, renovation of residential buildings, environmental improvement, infrastructure renovation and construction management measures. This study took Xukou Village renovation planning of Peixian County, Xuzhou City as an example, systematically and comprehensively analyzed the existing problems, and put forward targeted renovation strategies to build a village renovation planning system and to provide good experience and reference for the sustainable development of rural human settlements and provide reference and basis for the government to formulate relevant policies and take corresponding measures and solve practical problems. 展开更多

This study assessed the contribution of former poachers to wildlife conservation in Volcanoes National Park, the main causes of poaching activities in Volcanoes National Park. The results indicated that the main causes of poaching and other illegal activities are associated with poverty, ignorance and culture and commercial purposes. The results further illustrated that poaching cases decreased in the Volcanoes National Park where, from 2018, the snares removed from the park reduced from above 1000 to 600 snares. In the same year, only 3 poachers from Kinigi and Shingiro Sectors were arrested. The findings illustrated that introducing of revenue sharing scheme where, 10% of the park’s revenues are shared to the local communities living adjacent to the park, and constructing a buffalo wall stone around the Volcanoes National Park are of the important measures which contributed to solve completely the problems of poaching and human-wildlife conflicts in the volcanic area. However, some respondents reported that the construction of buffalo wall did not prevent animal from escaping the park, they have proposed the construction of strong fence such as electrically fenced wall. 展开更多

在开采煤层气、页岩气等气藏资源过程中,陶粒支撑剂的产品性能尤为关键,合成密度小、强度高的支撑剂是实现气藏高产率的重要指标。本文在传统矾土系陶粒支撑剂的基础上,添加煤矸石(RCG)、羧甲基纤维素钠(CMC)和白云石(DOL)进行固相烧结... 在开采煤层气、页岩气等气藏资源过程中,陶粒支撑剂的产品性能尤为关键,合成密度小、强度高的支撑剂是实现气藏高产率的重要指标。本文在传统矾土系陶粒支撑剂的基础上,添加煤矸石(RCG)、羧甲基纤维素钠(CMC)和白云石(DOL)进行固相烧结,借助以上造孔剂多温区的热解作用以及高温液相快速填充机制改善支撑剂的基体孔隙分布特征,降低支撑剂的结构密度并提升基体强度。当掺入质量分数为15%RCG+1%CMC+1%DOL添加剂时,支撑剂表现出最佳的综合性能并满足气藏资源开采的参数要求。 展开更多
