the objective of the present study is the synthesis of mwcnt-tio2 hybrid nanostructures by solvothermal synthesis method with ticl4 as precursor. the heat transfer enhancement due to the use of mwcnt-tio2 nanofluid was investigated. as-prepared hybrid materials were characterized by x-ray diffraction (xrd) and scanning electron microscopy (sem). the results showed that mwcnts were uniformly dec...

in order to evaluate the effects of intercropping of maize- peanut, weeding and their planting design on weed population dynamics, an experiment was conducted as a factorial experiment in the form of rcbd with three replications at the research farm of agriculture center of zabol university (iran) in 2012. the treatments including sowing system in four levels as first factor  (sole maize, sole ...

Keberadaan tanaman randu yang cukup melimpah serta kurangnya pemanfaatan minyak merupakan kesempatan besar untuk dikembangkan menjadi bahan dalam pembuatan biodiesel. Biodiesel dapat diperoleh dengan cara mereaksikan nabati alkohol menggunakan katalis pada suhu dan komposisi tertentu. Penggunaan heterogen, salah satunya CaO, biodiesel karena sifatnya lebih stabil, ramah lingkungan, korosi peral...

Motion is ubiquitous in the physical world, yet its study is much less developed than that of another common physical modality, namely shape. While we have several standardized mathematical shape descriptions, and even entire disciplines devoted to that area–such as Computer-Aided Geometric Design (CAGD)—the state of formal motion descriptions is still in flux. This in part because motion descr...

A retrospective study was conducted on 50 pregnancies in 41 kidney transplant recipients. 37 pregnancies were successful (74%), while in 13 cases the pregnancy was lost (7 abortions,S intra-uterine fetal deaths and one therapeutic termination). The pregnancy course was uneventful in 38 cases (76%) but in 12 there were complications, such as hypertension or slight rise in serum creatinine. ...

Abstract Glasses from two varieties of (LiF-B 2 O 3 ) and (LiF-P 5 systems with equal 50 mol % for each partner together samples doped 1 or 2% Bi were synthesized by melting–annealing mechanism. Multiple optical, FTIR photoluminescence spectral measurements carried out. Optical spectra —doped glasses exhibit UV-near visible peaks owing to the specific absorption 3+ ions. elucidate presence char...
