Background: Bone marrow aspiration and/or biopsy (BMAB) is a procedure used to diagnose and follow up various haematological diseases. It is usually performed at either the sternum or the iliac crest. Th e procedure oft en causes pain despite local infi ltration anaesthesia. Th e objective of this study was to evaluate diff erent means of pain relief during BMAB in adult patients. Special atten...
Removal of natural organic matter by ultrafiltration with TiO2-coated membrane under UV irradiation.
This study investigates the performance of ultrafiltration (UF) by membranes coated with titanium dioxide (TiO2) photocatalyst under ultraviolet (UV) illumination in removing natural organic matter (NOM) and possibly in reducing membrane fouling. Experiments were carried out using heat-resistant ceramic disc UF membranes and humic acids as model substances representing naturally occurring organ...
White matter architecture in patients with social anxiety disorder (SAD) has rarely been investigated, but may yield insights with respect to altered structural brain connectivity. Initial evidence points to alterations in the uncinate fasciculus (UF). We applied diffusion tensor imaging in 25 patients with SAD and 25 matched healthy subjects. Whole-brain fractional anisotropy (FA) maps were us...
Much attention has been focused recently on functional foods. Ume, the Japanese name for the apricot of Prunus mume Sieb. et Zucc., is an example of a Japanese traditional functional food. There are, however, few reports on the effects of fiber from this fruit on bowel function. With this objective, we prepared ume fiber to test the hypothesis that it can change gut function and intestinal flor...
در این مطالعه اثر نانو ذراترس بر خواص کاربردی تختهفیبر با دانسیته متوسط (MDF) مورد بررسی قرار گرفت. از نانو ذراترس سدیم مونت موریلونیت (NA+MMT) در سه سطح صفر، 3 و 6 درصد بر مبنای وزن خشک دو نوع رزین اوره فرمالدهید (UF) و متیلندیفنیلدیایزوسیانات (MDI) استفاده شد. مقاومتخمشی، مدولالاستیسیته، چسبندگیداخلی، جذب آب و واکشیدگیضخامت در 24 ساعت مورد ارزیابی قرار گرفتند. نتایج نشان داد که با ...
معادله بولتزمن معادلهای بسیار مهم در علم فیزیک و دینامیک سیالات است که برخوردهای دوتایی بین مولکولها را توصیف میکند. یکی از روشهای حل معادله بولتزمن، روش شبیهسازی مستقیم مونتکارلو میباشد. از آنجا که فشار اغلب تجهیزات واحدهای فرایند غنیسازی کمتر از فشار اتمسفر است، ممکن است در طی عملیات غنیسازی رطوبت هوا به دفعات و در مکانهای مختلف زنجیرهها به لوله سیال نشت کرده و طی و...
BACKGROUND Using diffusion tensor imaging (DTI), we previously reported abnormalities in two critical white matter tracts in schizophrenia, the uncinate fasciculus (UF) and the cingulum bundle (CB), both related to fronto-temporal connectivity. Here, we investigate these two bundles in unmedicated subjects with schizotypal personality disorder (SPD). METHODS Fifteen male SPD subjects and 15 m...
An experiment was conducted to investigate the effects of the resin solid content, catalyst content, and pH value obtained by the addition of two kinds of catalysts on the gel time of a urea–formaldehyde (UF) resin. Upon the addition of ammonium chloride, the pH value of the resin mixture decreased to 7 but not significantly further because of the limited free formaldehyde in the system. The pH...
