alumina-supported cs3[re(c2o4)3] precursor has been synthesized  for preparation of re-cs/g-al2o3 catalyst. cs3[re(c2o4)3]  has been prepared from the reaction of recl3 with  h2c2o4.2h2o and cscl in water. the complex has been characterized by elemental analysis and various spectroscopy techniques such as ft-ir, uv-vis and 13c-nmr. the complex was supported on γ-al2o3 by column chromatography. ...

The ease with which Tetrahymena can be grown in relatively large quantity makes it an exceptionally useful source of cilia for biochemical study. Several methods of isolating the cilia have been described (3, 11). Although excellent for many purposes, these procedures all suffer from the limitation that the isolated cilia seem incapable of being reactivated by ATP. This paper describes a method...

objective: non-compliance is one of the major problems in treatment of patients with schizophrenia. it is also the most significant risk factor for relapse and re-hospitalization. previous studies showed that 25-70% of all patients with schizophrenia have negative attitudes to drugs. therefore, the present study aimed to identify the relationship between drug attitude and discharge and the rate...

Study is carried out at National Key Lab of Plant Cell Biotechnology, Ho Chi Minh City, Vietnam. Vietnam has planning to re-culture coffea plant in area over 40.000ha South Good quality seedlings have a big demand. Using bioreactor technique the first method resolve lack seedlings. Stem, leaves vitro plantlets were used as planting materials. Somatic embryo callus was initiated on medium supple...

Plants can frequently experience low oxygen concentrations due to environmental factors such as flooding or waterlogging. It has been reported that both anoxia and the transition from anoxia to re-oxygenation determine a strong imbalance in the cellular redox state involving the production of reactive oxygen species (ROS) and nitric oxide (NO). Plant cell cultures can be a suitable system to st...

This paper introduces a novel passive suspension system for ground vehicles. This system is based on a flexible Electromagnetic Shock Absorber (EMSA). In the proposed system, efforts are made to a) select a high damping coefficient usable in a car b) determine Physical dimensions and geometry not much different from those of the mechanical shock absorbers and c) seletct EMSA weight and volume l...

We prove the conjecture of Berstein, Hilton, and Ganea that an (n I)-connected CW-complex X with dim X < k(n 2) + 3 which has a co-Ak_,-space structure desuspends. Moreover, we show the following dual of a result of Segal: given a cosimplicial space Y, which is special in the sense that the canonical maps Vz’, Yr + k;, are homotopy equivalences and Yl is 2-connected then there is a functorial d...

background: the rosemary extract (re) possesses various antioxidant, cytoprotective and cognition-improving bioactivities. in this study, we postulated which doses of re have a more effect on the hippocampus of middle-aged rats.   methods : in this experimental study, thirty-two middle-aged male wistar rats were fed by different doses (50,100 and 200 mg/kg/day) of re (containing 40% carnosic ac...
