all of the tea plantations in iran are concentrated in the caspian sea region on soils previously developed under deciduous natural forests. this research conducted to study the effect of land use change (from forest to tea) on selected physico-chemical and mineralogical properties of soils under humid climate and mountainous landscape in northern iran. three transects facing west to northwest ...
abstract sensitive and precise voltammetric methods for the determination of trace amounts of furaldehydes, mainly as furfural (f) and 5-hydroxymethyl-2-furaldehyde (hmf), in waste waters and other matrices is described. determination of total furaldehyde at < ?g g-1 levels in alkaline buffered aqueous media was individually investigated. by the use of ordinary swv and adsorptive square wave ...
OBJECTIVE Bisphosphonates are potent antiresorptive agents used for a spectrum of metabolic bone diseases. The aim of this study was to compare the adverse effects (AEs) of alendronate, etidronate and risedronate prescribed in a non-selected population, attending a single institution on an outpatient basis. DESIGN 849 patients receiving either alendronate (n=710), etidronate (n=181) or risedr...
abstract part one: the electrode oxidation potentials of a series of eighteen n-hydroxy compounds in aqueous solution were calculated based on a proper thermodynamic cycle. the dft method at the level of b3lyp-6-31g(d,p) was used to calculate the gas-phase free energy differences ,and the polarizable continuum model (pcm) was applied to describe the solvent and its interaction with n-hydroxy ...
Haemophilus influenzae type b (Hib) is a major cause of meningitis and pneumonia with high morbidity and mortality rates in young children. The introduction of effective and well-tolerated conjugate Hib vaccines, has nearly eradicated this disease in many countries. We investigated the safety of the Hib PRP-CRM197 vaccine in a multi-center post-marketing surveillance (PMS) study. Korean childre...
Potassium (K) fixation in soil is an important process which affects the availability of K to plants. There is limited information on K fixation capacity (PFC) of soils in Chahar Mahal & Bakhtiary province. This study was carried out with the aim of determining PFC and its relation with soil characteristics in 10 samples of surface soils in Chahar Mahal & Bakhtiary province. PFC was determined ...
In order to study the effects of different land uses on soil development, a loess hillslope was selected in Agh-Su area, eastern Golestan Province. Six profiles in four land uses including pasture, Quercuse natural forest, Cupressus artificial forest and a cultivated land, were dug and studied. Samples from different horizons were collected for physico-chemical and microscopic analyses. Importa...
introduction due to mining, considerable amounts of heavy metal bearing mineralsare scattered in the atmosphere in the form of dust and make the surrounding air, water and soils polluted.runoff water movingfrom the mountainstowardsplains may also transport heavy metals from mines to the soils.one type ofpollutions is contamination withheavy metals.the purpose of the present research has been to...
The use of lightweight cryptographic algorithms is essential for addressing security in highly constrained environments such as the Internet Things. In this paper, performance block ciphers studied. More precisely, focusing—as a case study—on an important family called “Saturnin”, which has been evaluated candidate standardization relative ongoing NIST’s competition, we analyze its efficiency t...
Building on the agri-environment framework in Central and Eastern Europe, article emphasizes role use of provision different ecosystem services. It shows that relevant conservation measures with regard to ameliorating soil degradation contribute existence sustainable land systems. In our study, we (i) identified what water aggregate means, (ii) reviewed how schemes (AES) function support requir...
