چکیده: در این تحقیق تأثیر ملاس که یکی از محصولات جانبی صنایع قند می باشد به عنوان یک افزودنی مقاومت خشک جدید در بهبود پالایش پذیری و ویژگی های فیزیکی و مکانیکی مقوای کنگره ای کهنه (occ) مورد بررسی قرار گرفته شد. بدین منظور پنج سطح ملاس( 0،5، 10، 15 و 18%) و سه سطح درجه روانی(420،400و320 میلی لیتر)به عنوان فاکتورهای متغیر در نظر گرفته شد و برای هر تیمار کاغذهای دست ساز با مساحت 2cm200 و وزن پای...
Introduction: Metabolic syndrome (MetS) and impaired lung functions have been associated with an increased risk for coronary heart disease. The aim of this study was to investigate the pulmonary functions in patients with MetS. Methods: This cross-sectional study included 200 subjects with MetS in the study group and 100 subjects without MetS in the control group. Participants were examined...
the current study examined iranian undergraduate efl students’ willingness to communicate with regard to their vocabulary knowledge. in general, participants were somewhat willing to communicate in english. the total mean score of 730 university students’ perception of willing to communicate was 83.53 out of 135. results, regarding four parts of willingness to communicate, revealed that part...
rust diseases continue to cause significant losses to wheat production around the world. among them, yellow rust caused by puccinia striiformis f. sp. tritici is an important disease that threatens wheat production in most cool environments. host resistance, especially race- nonspecific resistance, is the most economical way to manage wheat stripe rust disease. in this study, the effectiveness ...
Background and purpose: Application of nanomaterials is growing in removing various contaminants, pharmaceuticals, and in deactivation of water or sewage bacteria. However, the ability to degrade or eliminate the genetic components of bacteria by nanoparticles and preventing the increasing trend of antibiotic resistance from sewage treatment plants needs to be further investigated. This study a...
the objective of this experiment was to investigate inheritance and gene action for resistance to sunn pest (eurygaster integriceps) and related traits in bread wheat including f1, f2 and backcross generations derived from a cross between line 15 as resistance and line 12 as susceptible parents. parents along with f1, f2, bc1 and bc2 generations were evaluated in a randomized complete block des...
fusarium head blight (fhb) disease caused by fusarium graminearum is one of the most destructive diseases of wheat that in addition to the loss of product quality and quantity is able to produce the dangerous carcinogenic toxins in human and animals. in this study, the effects of different fertilizer treatments (vermicompost, chemical fertilizer and mycorrhiza) on performance components and exp...
Blast, Pyricularia grisea (Cooke) Sacc., is one of the most destructive diseases of rice worldwide and canresult in significant reductions in yield. The use of resistant cultivars is the most economical and effectiveway of controlling rice blast. A variety of DNA markers, including plant defense-related candidategene markers are available for genetic characterization and molec...
