Background: While articular chondrocytes are among those appropriate candidates for cartilage regeneration, the cell dedifferentiation during monolayer culture has limited their application. Several investigations have indicated the usefulness of alginate, but the topic of proliferation and differentiation of chondrocytes in alginate culture has still remained controversial. Methods: Rat articu...
for the first time nakayama introduced qf-ring. in 1967 carl. faith and elbert a. walker showed that r is qf-ring if and only if each injective right r-module is projective if and only if each injective left r-modules is projective. in 1987 s.k.jain and s.r.lopez-permouth proved that every ring homomorphic images of r has the property that each cyclic s-module is essentialy embeddable in dire...
abstract global financial crisis has created too many problems in relations among governments. among these problems, the issue of global monetary management, more than every time in the past four decades, has been moved in the center of international economic attentions. a problem which is specially known with the monetary hostility between united states and public republic of china. where ar...
Objective Manipulating the dietary fatty acid (FA) content can alter FA profiles of reproductive tissues. Numerous researchers have evaluated the effect of fish oil (FO) supplementation on reproductive characteristics in domestic animals, but reliable information concerning dietary FO effects on semen quality and testosterone concentrations in dogs has not been reported. Therefore, this study e...
the influence of freezing conditions on the organoleptic attributes of iranian leafy vegetable foods
the edible leafy vegetables contain nutritional ingredients that are necessary for human health and it is important that nutrients protection be monitored during processing and storage. the aim of this study was to study some organoleptic attributes of a very popular iranian meal named coco-sabzi, which was prepared with a mixture of edible grinded leafy vegetable pre-stored at different frozen...
the different factors such as harvest time, product handling, temperature and storage duration can be influenced on the different properties of citrus fruits and has considerable economic consequences. therefore a factorial experiment based on completely randomized design with 3 replications was performed to evaluate the effects of harvest times (start of color change, 50% of color change and f...
bserved by many teachers that most of the time, mumbling and searching for their intended words, students complain why they have forgotten the words they have learned in the previous semesters. they ask for some new ways that may help them to recall and apply the learned words more efficiently, since as they declare one of the most important skills in foreign language learning is having a g...
In this paper we prove that all the hyperbolic components of the family λ tan z except the punctured unit disk are simply connected. Then, restricting λ to the imaginary axis, We show that there is a “Sharkovskii-like” ordering of the periods of the hyperbolic components. Finally, again for λ in the imaginary axis, we show that period doubling phenomena occur.
