In injuries reducing ambulance response time (time from injury to hospital arrival) is an important factor for saving people’s lives. Helicopter emergency medical services can reduce out-of-hospital transport times because of their high speed and their ability to travel in straight paths?unlike ground ambulance which are restricted to road network paths, as well as the ability toaccess rural or remote area injuries that are difficult to reach by ground ambulance. GIS technology aids air ambulance movement planning to reduce out-of-hospital response time based on mathematical and geographic models to support decision making which is necessary from out-of-hospital care providers. The goal of this study is to use GIS to develop an efficient DSS to outline where air ambulance can reduce response times, by using spatial analysis tools to create Euclidean distance and direction zones around receiving hospitals. The study concludes that GIS technology can be used to develop an efficient DSS to outline where air ambulance can reduce response times, by creating surfaces of Euclidean allocation, direction, and distance that can be used to improve initial response times for the civil defense air rescue and air ambulance services.

随着科学技术的飞速发展,腿足型移动机器人已经活跃在人类生活的各个方面。尤其是四足机器人,由于其结构和控制简单、运动稳定性好、运动速度快等优点,而受到人们的青睐。本文介绍了一种利用五杆机构设计的准直接驱动腿足式移动机器人:SEU-doggo。该机器人具有垂直跳跃高、惯性小、运动速度快、结构简单、稳定性高、适应地形环境能力强等优点。提出SEU-doggo的设计方案,分析五杆机构腿足的结构与变位原理,为其在数字化设计平台上的应用提供参考。对四足机器人的腿足结构进行运动学分析与动力学分析,提出优化方案,确定满足使用需求的五杆机构腿足移动机器人。在此基础上,设计了五杆腿足移动机器人的控制系统,搭建与之匹配的控制模型。本文以SEU-doggo为研究对象,比较分析五杆机构的连杆长度与移动机器人的垂直跳跃性能之间的关系。证明了五杆机构准直接驱动四足机器人的性能优于串联腿驱动四足机器人,尤其是在跳跃敏捷性方面。最后,将SEU-doggo加工成实体样机,并搭建相应的实验平台。最终设计的SEU-doggo能够完成走路、小跑、跳跃等动作从而适应不同的场景。其机身体积很小(0.135m*0.19m*0.435m),质量轻、负载能力强。该机器人所使用的零件均可通过机加工与3D打印完成,零件尺寸较小,低成本,易福志,非常适合商业和教育使用。结果表明,对于垂直跳跃高度和腿部运动的敏捷程度两个指标而言,本文提出的方法比以往同类机器人获得了更好的设计效果。

This paper presents the design of a robust control system for a high-purity distillation column. It is concerned with the design of a two degree-of-freedom (2DOF) product-composition controller for a high-purity distillation column. The H∞ optimization problem is set up to ensure a guaranteed level of robust stability, robust disturbance attenuation and robust reference tracking performance.

Morphological descriptors and Random Amplification of Polymorphic DNA (RAPD) technique were used to assess the genetic variation among and within forty Pennesitum glaucum accessions from Sudan. Accessions were collected from 30 villages representing Darfur, North Kordofan, South Kordofan, and Blue Nile states. 64 amplified fragments were distinguished using ten primers.? 63 bands were polymorphic among the forty accessions with an average of 6.3 polymorphic bands per primer. Low level of genetic similarity was observed (4% - 43%). The PhiPT (analogue of FST fixation index) value for genetic variability obtained over the four regions was 0.169 with high significance (P = 0.01). AMOVA analysis showed higher variance components within regions (80%) than among regions (20%). The two dendrograms obtained by Random Amplification of Polymorphic DNA (RAPD) data;and morphological data based on 26 descriptors did not fit together. PCA (Principal coordinate’s analysis) showed geographic structuring of pearl millet according to its growing regions in Sudan.

Croplands are decreasing due to the expansion of urban areas into rural communities and to some extent due to sand accumulations. Increases in population numbers, new development, in addition to the accumulation of sand and soil salinity are the major driving force leading to abandonment and shrinking of cropland. The aim of this study was to investigate and assess to what extent agricultural lands are affected by urban development in the Al Hassa oasis, Eastern region in Saudi Arabia by employing Landsat time series data of years 1988, 2000 and 2017 as the main source of information. A set of ground truth, control points (GCPs) was also used besides population census data. Unsupervised classifications approach, Normalized Difference Vegetation Index (NDVI) and change detection methods were used here. Urban area during 2000-2017 exhibits much higher increase compared to 1988-2000, while the arable lands declined to −3.4% in 1988-2000 and increased to 22% during 2000-2017. The data analysis results provided new accurate numerical information supported by a graphical representation in regard to the decrease and increase in urban and agricultural lands. Therefore the findings of this study should be considered by decision maker for improving and development the agriculture activities in rural and urban communities.

Dear Editor,Human papillomavirus(HPV)is the most common sexually transmitted virus worldwide,and high-risk HPV infection is the most important risk factor for cervical cancer.1 However,few conclusive data are available on the prevalence of the male HPV infection and its health *** has been found that the prevalence of seminal HPV infection is higher in men with unexplained infertility,ranging between 10%and 35%compared with the general population(range:2%to 11%).2–4 In three recent systematic reviews,it was seen that HPV sperm infection may be associated with impaired sperm function that could lead to male infertility.2,4,5 HPV sperm infection with high-risk HPV among infertile men was shown to be associated with lower progressive sperm motility and higher DNA fragmentation index.6 Moreover,a high rate of pregnancy loss has been found among couples with HPV sperm infection after in vitro fertilization(IVF).7 In the majority of the studies performed to assess seminal HPV infection.
