Ecohydrological processes in tropical rainforests are insufficiently understood, and existing studies yield contradictory results. We investigated relative contributions of different soil depths to tree water uptake 83 trees possible species-specific differences a 50 × m forest plot at four dates montane Kenya using stable isotopes the Bayesian mixing model framework MixSIAR. found distinct ind...

Regarding rubber tree plantations, researchers lack a basic understanding of soil microbial communities; specifically, little is known about whether or not soil microbial variation is correlated with succession in these plantations. In this paper, we used high-throughput sequencing of the 16S rRNA gene to investigate the diversity and composition of the soil bacterial communities in a chronoseq...

In this survey, effective factors in little leaf disease on trees were studied in different pistachio orchards in Kerman province. Little leaf disease is the most serious disease of pistachio in Iran. Affected trees reduced growth rates. The first symptoms of little leaf disease are those of nutrient deficiency: a slight yellowing and shortening of the needles and reducing of shoot growth. New ...

introduction:the prevalence of atopic diseases has increased in recent decades dramatically. the most common aeroallergens in northeastern iran have not been fully defined. define the most common aeroallergens in allergic patients based on the skin prick test (spt) was aimed in this investigation.materials and methods:this cross-sectional study enrolled 1,006 allergic patients (aged 1–86 years)...

Evaporation is a fundamental parameter in the hydrological cycle. This study examines the performance of M5model tree and artificial neural network (ANN) models in estimating potential evapotranspiration calculated byPenman- Monteith and Hargreaves- Samani equations. Daily weather data from two meteorological stations in asemi-arid climate of Iran, namely Kerman and Zahedan, were collected duri...

The paper is devoted to concern a relationship between rough set theory and universal algebra. Notions of lower and upper rough approximations on an algebraic structure induced by an ideal are introduced and some of their properties are studied. Also, notions of rough subalgebras and rough ideals with respect to an ideal of an algebraic structure, which is an extended notion of subalgebras and ...

BACKGROUND Consensus-based approaches provide an alternative to evidence-based decision making, especially in situations where high-level evidence is limited. Our aim was to demonstrate a novel source of information, objective consensus based on recommendations in decision tree format from multiple sources. METHODS Based on nine sample recommendations in decision tree format a representative ...

introduction: estimation of cation exchange capacity (cec) with reliable soil properties can save time and cost. pedotransfer function (ptf) is a common method in estimating certain soil properties (e.g. cec) that has been wieldy used for many years. one of the common techniques that have been used to develop ptfs is multiple linear regressions. in this method, all easily obtained soil properti...
