Precipitation erosivity propels detrimental hydrological happenings with substantial eco-friendly and socio-economic influences. The conception of the precipitation-vegetation interface is very vital for implementing acclimatization mitigation techniques terrestrial bionetworks. Numerous investigations have reconnoitered spatial correlation context along season-precipitation quantity gradient. ...
Abstract. Most studies on validation of satellite trace gas retrievals or atmospheric chemical transport models assume that pointwise measurements, which roughly represent the element space, should compare well with (model) pixels (grid box). This assumption implies field interest must possess a high degree spatial homogeneity within box), may not hold true for species short lifetimes in proxim...
introduction the main problems relating to water quality for agriculture are salinity, soil infiltration and specific ions toxicity. accumulation of the specific ions from the irrigation water in the plants reduces crop yields. one of the most common specific ions toxicities results from high concentration of chloride (cl) ion. knowledge of the spatial distribution of cl concentration in ground...
The present work deals with two challenging problems of applied geostatistics: (i) Stationarity assumptions often do not hold under real-world conditions. (ii) Geostatistical methods have to be linked with spatial databases in order to be applicable in non-stationary situations. Solutions for both problems are proposed and implemented. (i) A central assumption in geostatistics is the stationari...
The spread of the COVID-19 pandemic has a simultaneous temporal and spatial component. This pattern results from complex combination factors, including social ones, that lead to significant differences in evolution space-time distributions, both between within countries. aim this study was assess changes regularity distribution number diagnosed cases Poland over more than year pandemic. analysi...
This study discusses the development of a prediction model for classification rainfall based on time in Java. The method used this research is naive Bayes and simple kriging. Naive prediction, while kriging an interpolation mapping. There are two scenarios used, that building daily monthly classification, with data taken from 27 weather stations island Java 2010 to 2021. results obtained proces...
In central Kenya, in the ecological transition zone from semi -humid to semi-arid, climatic and human induced land cover changes have an immense impact on the ecosystem. Therefore, investigations were made to analyse the potential to separate 10 detailed land use/land cover classes in this area from multitemporal ENVISAT ASAR data. Besides mean, different texture measures like variance, coeffic...
The spatial epidemiology of intestinal nematodes in Uganda was investigated using generalized additive models and geostatistical methods. The prevalence of Ascaris lumbricoides and Trichuris trichiura was unevenly distributed in the country with prevalence greatest in southwest Uganda whereas hookworm was more homogeneously distributed. A. lumbricoides and T. Trichiura prevalence were nonlinear...
A single blood cholesterol measurement may not accurately reflect an individual's true mean concentration. If duplicate blood samples are taken, what number of days between sampling gives the best chance of detecting the maximum within-subject variation? In this study, we analyzed 20 serial blood samples obtained from each of 13 healthy, menstruating women over 35 days. Variability was calculat...
