nanoparticles classified in 4 overall groups containing: metallic nanoparticles, ceramic nanoparticles, polymeric nanoparticles and semiconductor nanoparticles. these nanoparticles are used in some biomedical applications such as carrying medicine and photographing agents. with attention to different criteria which are both qualitative and quantitative, selecting the most suitable nanoparticles...
magnetic resonance imaging (mri) is a notable medical imaging technique that makes of phenomenon of nuclear magnetic resonance. because of the resolution and the technology being harmless, mri has considered as the most desirable imaging technique in clinical applications. the visual quality of mri plays an important role in accuracy of medical delineations that can be seriously degraded by exi...
this study investigated how group formation method, namely student-selected vs. teacher-assigned, influences the results of the community model of teaching creative writing; i.e., group dynamics and group outcome (the quality of performance). the study adopted an experimental comparison group and microgenetic research design to observe the change process over a relatively short period of time. ...
the central purpose of this study was to conduct a case study about the role of self monitoring in teacher’s use of motivational strategies. furthermore it focused on how these strategies affected students’ motivational behavior. although many studies have been done to investigate teachers’ motivational strategies use (cheng & d?rnyei, 2007; d?rnyei & csizer, 1998; green, 2001, guilloteaux & d?...
abstract in order to study the effects of quantitative and qualitative traits on cooking characteristics and protein percentage of 15 red bean genotypes, a randomized complete block design was conducted with three replications in normal irrigation and drought stress. these traits were measured in farm and nutrition laboratory employing international standard of ciat. analyses of variance showed...
The present investigation was aimed to study the qualitative and quantitative characteristics of Lebanon Oak (Quercus libani Olive.) in Marivan city-kordistan. To investigate the effect of altitude on the qualitative and quantitative characteristics of Lebanon Oak, 108 circular plots of 1000 m2 on three elevation classes of 1400-1600, 1600-1800 and 1800-2000 m were designated. Within each plot,...
it has often been stated or implied that grazing is an important factor in the land degradation process, a suggestion supported by various research projects, and this study investigated the effect of livestock grazing on stem height, crowncover, production, basal diameter, stem biomass, litter, leaf-stem index (leaf to stem weight) , root diameter and weight and seed production per individual o...
we studied 11 gaps covered with beech saplings (< 1.30 m tall) in a reserve compartment (compartment 139, district one, langa forest, watershed 36: kazemrood) of the caspian beech forest in n iran. two transects, each 2 m wide, were laid along the longest (n-s) and shortest (e-w) axis of each gap. five micro sample plots, each 4 m2, were established: one at the center, and one at each corner. q...
In order to study the effect of altitude on some quantitative and qualitative characteristic of Populus deltoides in Mazandaran province, three sites were selected with elevations between 150 and 1200 m above sea level in Sari city. In each site, some tree traits such as diameter at breast height, total height, basal area, volume, form factor and qualitative variables including trunk heal...
