this study was intended to analyze the listening tapescripts of the elementary and pre-intermediate levels of total english textbooks from the pragmatic dimension of language functions and speech acts in order to see whether the listening tasks are pragmatically informative or not. for this purpose, 8 conversations from the two books were selected randomly, and then, the two pragmatic models of...
چکیده در این پایان نامه ضمن معرفی توزیع وایبل، برآوردگر درستنمایی ماکزیمم و بیز پارامتر مقیاس توزیع وایبل با داده های سانسور شده را با استفاده از توزیع پیشین جفری و توزیع پیشین جفری تعمیم یافته تحت توابع میانگین مربع خطا و میانگین درصد خطا محاسبه و با یکدیگر مقایسه شده اند. در پایان ضمن مقایسه کارایی برآوردگرها نتیجه می شود که پارامتر برآورد شده توزیع وایبل بدست آمده از روش بیز با توزیع پیشین ...
Plastic Bonded Explosives with inert binder despite having good mechanical properties and low sensitivity, because of containing inert materials, have low energy level. So investigations for replacing inert binder system with energetic binder system and high exploding components in the making of these materials are performing. It seems using energetic polymers and materials like Cyclotetramethy...
Calcium phosphate ceramics has been widely used in the present due to their chemical similarity to bone and good biocompatibility in the physiological environmental and a compatibility with synthetic and natural polymers Recent advancements in additive manufacturing have enabled the fabrication of 3D prototypes with controlled architecture resembling the natural bone. Binder jetting is a versat...
The photocatalytic coatings were prepared via incorporating the modified titania nanoparticles into epoxy-based inorganic-organic hybrid coatings. Titania nanoparticles were first synthesized from tetra-n-butyl titanate using sol-gel methods by two different calcination treatments, i.e., in mild condition (80°C) and 500°C. The formed anatase nanoparticles were further modified as Titania-Silica...

based on the latest records of typhlops vermicularis merrem, 1820 from iran, this species is distributed in the northern and southern regions of the country. in this study, new records of typhlops vermicularis are presented and it is shown that distribution range of this species is extended towards the eastern and western iran, and according to the new distribution map, it can be assumed that t...
Microtubules (MTs) are key components of the cytoskeleton for all eukaryotes and are vital for cellular processes such as mitotic spindle formation, intracellular transport, vesicle formation, cellular signaling, and migration. These functions depend on the dynamic nature of MTs, which arises from the polymerization and depolymerization events of individual heterodimers, made up of αand β-tubul...
The rheological behavior of feedstocks used in powder injection molding technology influences strongly on the final properties of the products. Powder loading is one of the important factors that have a great distribution on rheological behaviors. By using the gas atomized spherical 316L stainless steel powder and the binder of 55% paraffin wax+ 40% polyethylen+ 5% stearic acid, four kinds of f...
