Marine animals are among the most important sources of natural products with biological activities because of their secondary metabolites. Many compounds were extracted, purified, identified and studied for their antioxidant, cytotoxic, anti-inflammatory and antibacterial effects from sea cucumber However, very few investigations are available on Persian Gulf sea cucumbers. The antioxidant act...

this research was conducted in two protect and destroy region in the middle zagros, in illam province. in order to identification of ecological species group and evaluate density of regeneration, effect of many factors such as protection, vegetation, physiographic factors, physical and chemical properties of soil in study locations were studied. to achieve these purpose number of 54 plots using...

abstract in aggregate, active forms of reactive silica with mineral names are sometimes associated with sand and gravel in concrete mixture. alkali hydroxides originated from alkalis in the cement or other resources form an alkaline silica gel with this reactive silica which becomes swallowed and expanded during time causing damage to concrete. there have been growing researches on alkaline r...

in the new age, in regard to human success in education in the globalizing world, one can consider english proficiency and individual differences as two important issues. in efl settings, reading skill plays an important role in education. it seems that using multiple intelligences theory in efl classes which values individual differences by tapping different intelligences, can be rewarding. as...

abstract the variables affecting the nature of reading comprehension can be classified into two general categories: reader’s variables, and text variables (alderson, 2000). despite the wave of research on vocabulary knowledge as reader’s variable, the role of this knowledge in c-test as a text-dependent test and its interaction with lexical cohesion of the test as a text feature has remained a...

Today, seaweed biofertilizers are widely used in the world to increase plant growth and yield. In order to study the effect of red seaweed on growth and physiological traits of squiring cucumber, this research was conducted in split plot experiment based on randomized complete blocks design with three replications during 2019. Experimental treatments consisted of three squirting cucumber genus ...

a novel and ultra low cost isfet electrode and measurement system was designed for isfet application and detection of hydronium, hydrazinium and potassium ions. also, a measuring setup containing appropriate circuits, suitable analyzer (advantech board), de noise reduction elements, cooling system and pc was used for controlling the isfet electrode and various characteristic measurements. the t...

Background and purpose: Biological studies on marine fauna, especially invertebrates, has significantly increased in recent years which led to the identification of many different bioactive compounds. The sea cucumber are echinoderms with a very muscular body wall that contains 70% collagen and is considered a rich source of protein. Based on recent researches on bioactive compounds extracted f...
