Introduction Quality control in clinical microbiology laboratories has tended to focus mainly on the accuracy of results obtained from the processing of specimens.`'3 Providing that external and internal quality control procedures are satisfactory, the laboratory may tend to assume that because the results produced are accurate, the service provided must be a good one. Users of the service, on ...

Leaf area index (LAI) and biomass are frequently used target variables for agricultural and ecological remote sensing applications. Ground measurements of winter wheat LAI and biomass were made from March to May 2014 in the Yangling district, Shaanxi, Northwest China. The corresponding remotely sensed data were obtained from the earth-observation satellites Huanjing (HJ) and RADARSAT-2. The obj...

biological invasions form a major threat to the provision of ecosystems productsand services and can affect ecosystems across a wide spectrum of bioclimatic conditions.therefore, it is important to systematically monitor the spread of species over broad regions. ithas long been recognized that remote sensing and geographical information system couldcontribute to this capacity. this paper aims t...

In this paper, we present an identification of rockfall-injured trees based on multiband images obtained by unmanned aerial vehicle (UAV). A survey with a multispectral camera was performed three rockfall sites versatile tree species (Fagus sylvatica L., Larix decidua Mill., Pinus sylvestris Picea abies (L.) Karsten, and Abies alba Mill.) different characterizations rockfalls rockfall-induced i...

In view of the demand for a low-cost, high-throughput method for the continuous acquisition of crop growth information, this study describes a crop-growth monitoring system which uses an unmanned aerial vehicle (UAV) as an operating platform. The system is capable of real-time online acquisition of various major indexes, e.g., the normalized difference vegetation index (NDVI) of the crop canopy...

Cotton yield varies spatially within a field. The variability can be caused by various production inputs such as soil properties, water management, and fertilizer application. Airborne multispectral imaging is capable of providing data and information to study effects of the inputs on yield qualitatively and quantitatively in a timely and cost-effective fashion. A 10-ha cotton field with irriga...

OBJECTIVES To assess whether fully normalised vertical ground reaction forces and stance times obtained at a trot depend on dog breed or body conformations. METHODS Peak vertical forces (PVF), vertical impulses (VI), stance times (ST), and ratio of forelimb impulse to total impulse (RVI) of 54 dogs of seven different breeds were normalised to body weight and body size according to the theory ...

The genetic consequences and gene fl ow of pikeperch ( Sander lucioperca ) stocking were assessed in three boreal lakes based on admixture model analysis and comparison of the preand post-release patterns of genetic variability at 9 DNA microsatellite loci in the recipient populations. In two out of the three cases, the releases of fi sh from foreign populations caused signifi cant changes in t...

Osmotic cell volume perturbations of rabbit proximal tubule (PT) in primary culture were measured using three independent techniques. Automatic cell thickness monitoring of PT monolayers revealed that cell volume rapidly increased by 39 +/- 2% in hypotonic medium (150 mosM), which was followed by partial regulatory volume decrease (RVD). Subsequent incubation in hypertonic medium (500 mosM) rap...

Introduction. RVI (rotavirus infection) is the most common cause of dehydration in infants and young children. The implementation sentinel surveillance from 2008 Republic Moldova demonstrated high rate this infection (40.0%), being an argument recommending antirotaviral immunization children within National Immunization Program.
