Scientific miracle is one of the aspects of miracle in the Holy Quran. The Holy Quran includes verses referring to scientific fact, those proved by development of human knowledge and scientific equipments after passing 14 centuries from the revelation of the Quran. The verse 4 of Munafiqun verse: "as though they were blocks of wood in striped cloaks" is among those verses which, based on a spec...
in this thesis, we exploit a simple and suitable method for immobilization of copper(ii) complex of 4?-phenyl-terpyridine on activated multi-walled carbon nanotubes [amwcnts-o-cu(ii)-phtpy]. this nanostructure was characterized by various physico-chemical techniques. to ensure the efficiency and fidelity of copper species, the implementation of three-component strategies in click-chemistry all...
for the first time nakayama introduced qf-ring. in 1967 carl. faith and elbert a. walker showed that r is qf-ring if and only if each injective right r-module is projective if and only if each injective left r-modules is projective. in 1987 s.k.jain and s.r.lopez-permouth proved that every ring homomorphic images of r has the property that each cyclic s-module is essentialy embeddable in dire...
PREMISE OF THE STUDY Field methodology and image analysis protocols using acoustic tomography were developed and evaluated as a tool to estimate the amount of internal decay and damage of living trees, with special attention to tropical rainforest trees with irregular trunk shapes. METHODS AND RESULTS Living trunks of a diversity of tree species in tropical rainforests in the Republic of Pana...
PREMISE OF THE STUDY Wood density correlates with mechanical and physiological strategies of trees and is important for estimating global carbon stocks. Nonetheless, the relationship between branch and trunk xylem density has been poorly explored in neotropical trees. Here, we examine this relationship in trees from French Guiana and its variation among different families and sites, to improve ...
The objective of this study was to characterize the energy parameters wood and production from a seven-year-old experimental plantation Eucalyptus saligna. For purpose, information collected an planting spaced at 3.0 m x in Chapadão do Sul, MS, Brazil. Values were obtained for diameter height trees, which felled rigorously cubed obtain volumes wood. Wood plantations characterized relation to: p...
background: organic nitrates relax all kinds of smooth muscle , not only vascular smooth muscle , a fact that has allowed the use of these drugs to treat many different aliments. objective.-the purpuse of this study was to examine prosepectively benefical effects , if any, of sublingual nitroglycerin on the pain of renal colic. design.- prospective , randomised , double blind, placebo- contoled...
AIMS To develop fast and reliable sampling procedures for DNA-based diagnosis of wood decay fungi in standing trees. METHODS AND RESULTS A total of 250 trees were tested for the presence of a suite of wood decay fungi by collecting wood frass obtained by drilling each tree once with a 4-mm-diameter, 43-cm-long bit. We identified at least one of 11 target wood decay fungi in 56 trees through m...
background oxidative stress plays a major pathogenic role in liver injury following chronic hepatitis b. glutathione peroxidase (gpx) has a central role in regulating the oxidative state. hepatitis b virus (hbv) results in down-regulation of gpx. on the other hand, iron homeostasis is disrupted in hbv infected patients. therefore, the objective of this study was to assess the interplay of gpx a...
the oriental beech constitute one third of northern forests area and stocking volume in the north ofiran. these stands obseve in pure and mixed. in order to properly management which guaranteesustained yield, it is crucial to collect basic information including stocking (volume and stem number),tree growth, diameter distribution pattern, diameter-height relationship, diameter-volume relationshi...
