BACKGROUND Melioidosis is a frequently fatal infectious disease caused by the soil dwelling Gram-negative bacterium Burkholderia pseudomallei. Environmental sampling is important to identify geographical distribution of the organism and related risk of infection to humans and livestock. The aim of this study was to evaluate spatial distribution of B. pseudomallei in soil and consider the implic...

Researchers are increasingly able to capture spatially referenced data on both a response and a covariate more frequently and in more detail. A combination of geostatisical models and analysis of covariance methods may be used to analyze such data. However, very basic questions regarding the effects of using a covariate whose support differs from that of the response variable must be addressed ...

Fan Zhen Lecture Cryogenic Division In this paper, a new mathematical model to calculate gas leakage in small clearance is established. In the model, viscous force and inertia force are considered at the same time. Theoratical analysis and experimental results show that the calcuating results coincide well ·with the experimental results.

Geostatistics combined with GIS spatial technology was applied to analyze the time and spatial variability of pH in topsoil(0-20cm) for planted tobacco region in Sanmenxia district. The results indicated that the pH value range form 6.5 to 8.8 and meet to the need of produce high quality tobacco, but the pH value of partial region is high. The pH value accord with logarithm normal distribution,...

This paper took the wheat field of typical alluvial soil area as the research site, aimed to explore the spatial pattern of the soil nutrients, such as soil available potassium, soil available phosphorus, soil organic matter (SOM) and soil alkali hydrolysable nitrogen. With the help of DGPS, a total of 104 topsoil(0–20cm) samples were collected. Based on classical statistics, research results i...

Der urbane Raum wird zunehmend intelligenter. So können Passanten mit Druckknöpfen an Ampelanlagen spielen, um die Rotphase zu überbrücken, Informationstafeln an Bushaltestellen zeigen Verspätungen des Busses an und WLAN-Technologie erlaubt das Erfassen der Bewegung unterschiedlicher Akteure im Raum. Die Vorteile aus dieser Vernetzung, stehen jedoch älteren Personen mit kognitiven oder motorisc...

To evaluate torque loss a week after insertion, both in an in vivo and an in vitro experimental setup were designed. In the in vivo setup a total of 29 miniscrews were placed in 20 patients who underwent orthodontic treatment. Maximum insertion torque (MIT) was evaluated at insertion time (T1). A week later, insertion torque was measured again by applying a quarter turn (T2); no load was applie...
