To study the feasibility of using two edible plant oils as diesel substitute a comparative study was made. Oils were exacted from the seeds of soyabean (Glycine Max, Family: Leguminoceae) and sunflower(Helianthus annuus, Family: Asteraceae/Compositeae). Oils were esterified (butyl esters) before blending with pure diesel in the ratio of 10:90, 15:85, 20:80, and 25:75 by volume. Pure diesel was ...
This paper describes the literature review of effect of different nano additives on performance and emission characteristics of diesel engine fuelled with different blends of biodiesel. This study is based on the previous research published articles. It was reviewed that by using nano additives with blend of biodiesel the performance characteristics were improved significantly but the exhaust e...
Polycaprolactone (PCL) and poly(butylene terephthalate) (PBT) blend was prepared by melt processing. The PCL/PBT blend showed similar morphology with that of pure PCL.The crystallization temperature of PCL was increased by the incorporation of PBT. It was also observed that the peak height in the DSC thermograms decreased and then disappeared by adding 40 % or more PBT which might be due to...
Mimicking one or more components of the basement membrane (BM) holds great promise for overcoming insufficiencies in tissue engineering therapies. We have electrospun laminin nanofibers (NFs) isolated from the murine Engelbreth-Holm Swarm (EHS) tumor and evaluated them as a scaffold for embryonic stem cell culture. Seeded human embryonic stem cells were found to better maintain their undifferen...
BACKGROUND Hematoma expansion is associated with poor outcome in intracerebral hemorrhage (ICH) patients. The spot sign and the blend sign are reliable tools for predicting hematoma expansion in ICH patients. The aim of this study was to compare the accuracy of the two signs in the prediction of hematoma expansion. MATERIAL AND METHODS Patients with spontaneous ICH were screened for the presenc...
backgrounds and objectives: in recent years, food industries and scientists are about to decrease the energy intake of food products according to the rising rate in obesity and the problems of consuming high-caloric products. considering all the benefits the sucrose possess as a natural sweetener, due to some health issues such as, high blood pressure, obesity, cardiovascular diseases, tooth de...
We describe a method to generate blend surfaces which t with continuous curvature to the primary surfaces. This blend surface is obtained as the bicubic tensor spline minimizing a variational problem. Among all the bicubic tensor splines which give a curvature continuous blend surface, the one is chosen which minimizes a bilinear functional. In Section 2 we summarize and extend the results of a...
PURPOSE We tested the effects of a saw palmetto herbal blend in men with symptomatic benign prostatic hyperplasia (BPH) via a randomized, placebo controlled trial. MATERIALS AND METHODS We randomized 44 men 45 to 80 years old with symptomatic BPH into a trial of a saw palmetto herbal blend versus placebo. End points included routine clinical measures (symptom score, uroflowmetry and post-void...
Fabrication of nanocomposites from immiscible polymer blend system has been represented in this work. A new type of natural clay named Halloysite Nanotubes (HNTs) are modified by Polyethyleneimine (PEI) and these PEI grafted HNTs are incorporated into the immiscible blend system during melt mixing process to prepare halloysite based nanocomposites. Fourier Transform Infrared Spectroscopy (FTIR)...
