Ferula persica, is the well-known species of the genus Ferula in Iran and has two varieties: persica and latisecta. They have both been extensively used in traditional medicine for a wide range of ailments. A great number of chemical compounds including sesquiterpene coumarins and polysulfides have been isolated from this plant. Fresh plant materials, crude extracts and isolated components of F...

Realization of a novel single-resistance-controlled oscillator, employing an active element and all grounded passive elements, is the purpose of this manuscript. With requirements for completing the design being only a single Voltage Differencing Current Conveyor and four grounded passive components, it is also a preferable choice for integrated circuit implementation. The designed circuit has ...

Satisfactory methods, utilizing measurements of transthoracic or transpulmonary pressure and airflow, are now available for determining "nonelastic" pulmonary resistance. However, the nonelastic pulmonary resistance has two components, tissue resistance and airway resistance, and no valid direct method is available for measuring either of these components separately in man. Since airway resista...

A study on response of 29 barley genotypes resistant to Bipolaris leaf blight (Bipolaris sorokiniana) was conducted to investigate the relationship of the components of resistance of 29 barley genotypes. Data on five components of resistance viz., infection frequency (number of lesions per plant), lesion size (mm), percent leaf area affected by lesion, percent necrotic area on leaf, and disease...

to survey the effects of nutritional and growth regulator components on adverse effects of recent consecutive droughts, an experiment was conducted on uniform grape trees (vitisviniferal.clv.'khalili') in bavanat and shiraz (akbar-abad) regions in 2010- 2011.trial was arranged in a randomized complete blockdesign (rcbd), with three replication and five trees per each plot. experimental treatmen...

Nickel base superalloy alloys are used in the manufacture of gas turbine engine components, which in use are exposed to high temperatures and corrosive environments. The platinum aluminide coatings described here have been developed to protect nickel base superalloy alloys from oxidation. In this study, the effect of cyclic oxidation, platinum layer thickness and aluminizing process on beha...

metabolic syndrome, a clustering of components that reflect overnutrition, sedentary lifestyles, and excess adiposity, has become a major health problem worldwide. the increase in its prevalence could be the result of the increase in obesity and insulin resistance. it is suggested that modification of lifestyle including increasing exercise and improving dietary habits is an effective approach ...
