distribution of magnetic fields in the quiet-sun internetwork areas has been affected by weak polarization (in particular stokes q and u) signals. to improve the signal-to-noise ratio (snr) of the weak polarization signals, several approaches, including temporal integrations, have been proposed in the literature. in this study, we aim to investigate a proper temporal-integration time with which...

introduction: the main agents of sarcocystosis in cattle as an intermediate host include s. cruzi, s. hominis and s. hirsuta. a sensitive and specific tool such as molecular-based techniques would be necessary to identify the species. case report: after collection of beef sample from yazd slaughterhouse, dna extraction was done with salting out method. the 18srrna gene as a specific target gene...

measurement systems analysis (msa) has been applied in different aspect of industrial assessments to evaluate various types of quantitative and qualitative measures. qualification of a measurement system depends on two important features: accuracy and precision. since the capability of each quality system is severely related to the capability of its measurement system, the weakness of the two ...

the presence of tumor thrombus in the right atrium is frequently the result of direct intraluminal extension of infra-diaphragmatic malignancy into the inferior vena cava (ivc) or supradiaphragmatic carcinoma into the superior vena cava (svc). right atrial tumor thrombus with extension into both svc and ivc has not been reported in the literature. we present a patient who presented with symptom...

objective: to obtain abnormalities in quantitative electroencephalography qeeg) and to observe connectivity between electrodes in children with asperger disorder. method: in this study, spectrogram criteria and coherence values are used as a tool for evaluating qeeg in 15 children with asperger disorder (10 boys and 5 girls aged between 6 to 11 years old) and in 11 control children boys and 4 g...

objective: to evaluate the brain signals in children with autism disorder in many different conditions of quantitative electroencephalography (qeeg) recordings in order to highlight abnormalities and to characterize this group. method: in this study, spectrogram was used as a tool for evaluating qeeg in 15 children with autism disorders (13 boys and 2 girls aged between 6 to 11 years old) and i...

background: fatty acids are known to be critically important in multiple biological functions. phospholipid fatty acids of follicular fluid, an important microenvironment for the development of oocytes, may contribute to the women’s fertility and the efficacy of assisted reproduction techniques. the aim of this study was to investigate the effect of fatty acid composition of follicular fluid ph...

this article reviews the development of non-invasive optical techniques for determination of blood glucose concentrations in diabetic patients. early diagnosis and daily management are essential for ensuring the healthy life of diabetic patients. the determination of blood glucose concentration with common devices involves the chemical analysis of blood samples, which are obtained by pricking t...

photorefractive keratectomy is a preprogrammed surface corneal refractive ablation which is aimed to reduce or eliminate myopia, hyperopia or astigmatism through the removal of the corneal surface epithelium and basement membrane and the application of excimer laser photoablation to bowman membrane and anterior stroma. the epithelium then begins to cover the wound, in direct contact with the an...

background: in recent years, the high likelihood of the implantation of transferred embryos has led to an increase in the number of multiple pregnancies and consequently an increased risk of complications in fetuses and mothers. since the aim of infertility treatment is the birth of a healthy child while preserving the mother’s health, therefore, attempts should be made to avoid multiple pregna...
