due to the need to find new protein sources with considering the fact that the bitter vetch seed has high levels of protein content, physicochemical and mechanical properties of bitter vetch seed and functional properties of its flour were evaluated in this study. the effects of altering the ph on protein solubility, foaming capacity, foaming stability, emulsion capacity and emulsion stability ...
Background and Aim: Intraosseous implants can be placed using three different techniques: immediate, early, and delayed. The aim of this study was to compare the changes in the marginal bone level around implants after immediate and delayed im-plant placement. Materials and Methods: In the present prospective cohort study, 26 implants were placed in 26 patients divided into two groups. In grou...
this work is presented in five parts. in the first part preparation of the starting complex [pt(c^n)cl(dmso)], 1, in which c^n = n(1),c(2?)-chelated, deprotonated 2-phenylpyridine, and dmso = dimethylsulfoxide, and its reaction with 1 equiv of the biphosphine ligands bis(diphenylphosphino)amine, dppa, or bis(diphenylphosphino)methane, dppm, to give the complex [pt(c^n)cl(dppa)], 2, or [pt(c^n)c...
in this study, moisture dependent physical, mechanical and nutritional properties of sesame seed were evaluated. in the moisture range of 4.54–19.27% (d.b.), seed length, width, thickness, arithmetic mean diameter and geometric mean diameter increased linearly from 2.93 to 3.01 mm, 1.74 to 1.78 mm, 0.78 to 0.86 mm, 1.81 to 1.88 mm and 1.58 to 1.66 mm respectively with increase in moisture conte...
the purpose of this thesis was to investigate how differently metacognitive, cognitive, and social/affective strategies affect l2 learners’ reading comprehension. to this end, the study employed a quasi-experimental design with a placement test as a proficiency test to find the homogeneity of groups. three classes were randomly selected as the experimental groups (n =90), and each class was tau...
Roasting is the most common way for pistachio nuts processing, and the purpose of that was to increase the products total acceptability. Purpose of this study was to investigate the effect of temperature (90, 120 and 150°C), time (20, 35 and 50 min), and roasting air velocity (0.5, 1.5 and 2.5 m/s) on geometrical attributes of pistachio nuts and kernels including principle dimensions, shape fac...
AIMS exercise may dramatically change the extent of functional mitral regurgitation (MR) and left ventricular (LV) geometry in patients with chronic heart failure (CHF). We hypothesized that dynamic changes in MR and LV geometry would affect exercise capacity. METHODS AND RESULTS this study included 30 CHF patients with functional MR who underwent symptom-limited bicycle exercise stress echoc...
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. ...
Purpose The purpose of this study was to quantify variations in the heart, pericardium, and left ventricular myocardium (LVM) caused by cardiac movement using the breath-hold technique. Patients and methods In this study, the electrocardiography-gated four-dimensional computed tomography (CT) images of 22 patients were analyzed, which were sorted into 20 phases (0-95%) according to the cardia...
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 . ...
