Recently investigators have reported knob-like particles on mitochondrial membranes isolated from different organisms (1, 2, 4, 5). This report presents observations on the structure of plant mitochondria, negatively stained with phospho-tungstic acid, which show knob-like projections on the membranes. MATERIALS AND METHODS Castor beans (Ricinus communis) were soaked for 24 hours in distilled w...
This paper describes a motion controller for differential drive vehicles with a compensation for castor wheel turn forces. The controller has been developed for electric wheelchairs with two front castor wheels, which require large steering forces to move into the direction given by the joystick in situations where a sharp turn of the castor wheels is needed. It computes the required forces to ...
Castor oil was first noted to have oxytocic properties by ancient Egyptians. Derived from the castor plant Ricinus communis, castor oil may possess properties that are useful are in post-term pregnancies This study was performed at Khatam-Alanbia, hospital in shoushtar city in 1381.In this clinical trail 80 pregnant women, who had indication for induction of labor at term were randomly assigned...
Re-Evaluation of Sinocastor (Rodentia: Castoridae) with Implications on the Origin of Modern Beavers
The extant beaver, Castor, has played an important role shaping landscapes and ecosystems in Eurasia and North America, yet the origins and early evolution of this lineage remain poorly understood. Here we use a geometric morphometric approach to help re-evaluate the phylogenetic affinities of a fossil skull from the Late Miocene of China. This specimen was originally considered Sinocastor, and...
Castor plant (Ricinus communis L.) produces a unique seed oil with numerous industrial applications. However, castor seed contains toxin ricin and hyper-allergenic 2S albumins detrimental to castor grower and processor. Our project goal is to develop a safe source of castor oil through genetic engineering. The general approach is to generate a safe castor crop by blocking expression of the rici...
Crude glycerol (CG) is an abundantly available and cheap by-product from biodiesel production. Value-added applications for CG are highly wanted by industry and several processes such as the use of CG for enhanced oil recovery have been proposed. The aim of this study was to evaluate the sulfide production of sulfate-reducing bacteria (SRB) indigenous to oil reservoirs using CG as substrate. Th...
