a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...
چکیده مورچهها با حمایت از شپشکها در مقابل دشمنان طبیعی، میتوانند برنامههای کنترل بیولوژیک آنها را مختل نمایند. طی سالهای 1389 و 1390 با نمونهبرداری از باغات مرکبات شهرستانهای ساری و بهشهر، فون و فراوانی نسبی مورچههایِ همراه با شپشکها مورد مطالعه قرار گرفت. همچنین، تاثیر تراکمهای مختلف کاست کارگر گونهی santschi lasius turcicus بر میزان تغذیه و فراسنجههای واکنش تابعی حشرات ماده و لا...
abstract translation has become a cultural act which plays a significant role in human life. with the emergence of functional translation theories, and skopos theory in particular, translation has been considered as a purposeful, interpersonal and intercultural activity which is produced for particular recipients and directed by a specific purpose. this purpose determines the translatio...
normal skin is composed of epidermis and dermis. skin is susceptible to radiation damage because it is a continuously renewing organ containing rapidly proliferating mature cells. radiation burn is a damage to the skin or other biological tissues caused by exposure to radiofrequency energy or ionizing radiation. acute skin reaction is the most frequently occurring side effect of radiation thera...
Background: Exposure to ionizing radiation is inevitable. Using of low-level laser therapy (LLLT) stimulates tissue repair and reduces inflammation. The objective of the present study aimed at evaluating the therapeutic efficacy of Helium-Neon (He-Ne) laser in stimulating the reparative processes in the liver of mice after whole body gamma-irradiation (WBγ-I). Materials and Methods: Two hundred...
introduction: in this study, arrangement of a low-cost optical tomography device compared to other methods such as frequency domain diffuse tomography or time domain diffuse tomography is reported. this low-cost diffuse optical imaging technique is based on the detection of light after propagation in tissue. these detected signals are applied to predict the location of in-homogeneities inside p...
abstract in first part of this project, the use of a new and biguanid-like catalyst supported on silica as a recyclable catalyst provides a new route for the synthesis of a variety of arylalkylidene rhodanine derivatives through knoevenagle reaction in at present of solvent at room temperature. rhodanine derivatives and especially arylalkylidene rhodanines have proven to be attractive compound...
Due to the differences in the composite and morphology of dentin in primary and permanent teeth, it is necessary to make improvements in bonding techniques to promote the strength of composite resins bonded to the dentinal surface, in primary teeth. The use of lower radiation, to make structural and chemical changes in dentinal surfaces has been investigated. This research was conducted to eval...
this study was an attempt to investigate the effect of teaching meta cognitive strategies on iranian intermediate efl students speaking proficiency. in this study the researcher has employed metacognitive strategies taken from brown (2000) to teach speaking strategies to number of participants. the participants were intermediate students of shokouh language institute; they were divided into an ...
This study was conducted to examine and compare the clinical response of patients with small hemangiomas treated with two non-ablative lasers with wavelength radiation 755 nm and 595 nm. The treatment efficacy – curative effect and loss of pigment and appearance of scars were compared using Pearson’s chi-square test. The therapeutic effect of 595 nm laser radiation was very high – almost 100%. ...
