this research was conducted in two protect and destroy region in the middle zagros, in illam province. in order to identification of ecological species group and evaluate density of regeneration, effect of many factors such as protection, vegetation, physiographic factors, physical and chemical properties of soil in study locations were studied. to achieve these purpose number of 54 plots using...
Marketing of agricultural products is being considered as one of the most fundamental and important measures for development in rural environments. As such, the identification of responsible factors for marketing of perishable products namely dairy products could facilitate marketing process and as a result diminish the associated problems in local communities. The identification of responsible...
Background and Objectives: Public health issues and the spread of disease correlate with geography and always have locational aspects.. Therfore, in this study the spatial analysis of malaria disease reports between 2004-2014 in Bam were investigated using geographic information system (GIS). Materials and Methods: In this cross-sectional study, information on positive cases of malaria were ...
This paper focuses on the analysis of spatially correlated functional data. We propose a parametric model for spatial correlation and the between-curve correlation is modeled by correlating functional principal component scores of the functional data. Additionally, in the sparse observation framework, we propose a novel approach of spatial principal analysis by conditional expectation to explic...
Seed production that varies greatly from year to year, known as "masting" or "mast-fruiting" behavior, is a population-level phenomenon known to exhibit geographic synchrony extending, at least in some cases, hundreds of kilometers. The two main nonexclusive hypotheses for the driver of such geographically extensive synchrony are (1) environmental factors (the Moran effect), and (2) the mutual ...

BACKGROUND: Giardia is the most frequently identified intestinal parasite in North America. Although information on geographical distribution of giardiasis is critical in identifying communities at high risk, little has been done in this area. Therefore, the objective of this study was to investigate the geographical and temporal distribution of human giardiasis in Ontario in order to identify ...
with the increasing population and the need for more food, as well as with the development of science and technology, human approach to unnatural and often chemical inputs to increase agricultural production has been a great expansion and problems such as increased cancers, chronic diseases has created environmental pollution. implementation of organic organic is a solution to these problems . ...
OBJECTIVE To identify the spatial pattern of low birth weight infants in the city of Taubaté, São Paulo, Southeast Brazil. METHODS Ecological and exploratory study, developed with the data acquired from the Health Department of Taubaté, regarding the period from January 1(st) 2006 and December 31(st) 2010. Birth certificates were used to obtain the data from infants weighing less than 2500g. ...
Strong spatial correlation may exist in the spatial succession of biological communities, and the spatial succession can be mathematically described. It was confirmed by our study on spatial succession of both plant and arthropod communities along a linear transect of natural grassland. Both auto-correlation and cross-correlation analyses revealed that the succession of plant and arthropod comm...
