The use of polymer in hot mix asphalt production has remarkably in recent decades. Destruction due to moisture in hot mix asphalt is of basic matters about flexible pavement durability. In recent decades different ways have been used to evaluate moisture Sensitivity of HMA which some of them are simple with low cost and some are complicated with more reliable results. In this research the effec...
abstract in this study, we synthesized a novel template polymer by using methacrylic acid (mma) as functional monomer, ethylene glycol dimethacrylate(egdma) as cross linker, 2,2-azobisisobutyronitrile (aibn) as initiator and olanzapine as targeted molecule in the presence of chloroform and acetonitrile as solvent. the products have been characterized and confirmed by (chn)elemental analysis,...
objective: pmbn, poly [2-methacryloyloxyethyl phosphoryl choline (mpc)-co-n- buthyl methacrylate (bma)-co-p-nitrophenyl- oxycrabonyl poly (ethylene glycol-methacrylate (meonp)], as a biocompatible ter-polymer is a unique polymer with wide range of application from drug delivery systems to scaffolds and biomedical devices. in this research, monomer of p- nitrophenyl- oxycarbonyl poly (ethylene g...
in this thesis, we exploit a simple and suitable method for immobilization of copper(ii) complex of 4?-phenyl-terpyridine on activated multi-walled carbon nanotubes [amwcnts-o-cu(ii)-phtpy]. this nanostructure was characterized by various physico-chemical techniques. to ensure the efficiency and fidelity of copper species, the implementation of three-component strategies in click-chemistry all...
در این پایان نامه یک مدل برآورد هزینه های ادواری جهت برآورد هزینه عرشه های ساخته شده از ترکیبات fiber reinforced polymer(frp) ارائه شده است. این مدل تمامی هزینه های کارفرما، هزینه های بهره بردار و هزینه های طرف سوم را در جهت تخمین و برآورد هزینه های ادواری عرشه های frp در دوره عمر مفید پل در نظر می گیرد.
to investigate effects of different super absorbent polymer and animal manure ratios on the quantitative and qualitative characteristics of soybean under drought stress, a split plots experiment was conducted based on randomized complete block design with three replications in marvdasht, iran in 2009. main factor included of irrigation with 50, 100 and 150 mm evaporation from pan class a and su...
kevlar is one of the fbers which is used in heavy industrial productions such as, shipping, military and weaving for reinforcement of composites. initial polymer of kevlar or poly(para-phenylene terephthalamide) is an oriented liquid crystal polymer. existence of aromatic group in the main chain leads to formation of rigid-rod molecules in the polymer, high strength and high modulus in it is fb...
introduction the purpose of the current study was to determine optical sensitivity of n-isopropyl acrylamide nipam and polyacrylamide gelatin and tetrakis hydroxymethyl phosphoniun chloride (pagat) polymer gels for different wavelength of visible light spectrum applied in optical computed tomography method. materials and methods nipam and pagat polymer gels with conventional formulations used f...
The object of this research is the investigation of carbon nanotube (CNT) distribution effect on electrical conductivity of polymer-CNT composite as dosimetry response of this system. Thus, electrical conductivity of this composite was simulated for aligned, homogenous, and agglomerated distributions in 2D, and 3D situations. The results of simulation were compared and validated by experimental...
knowledge of physiological and environmental factors is important for foragegrass production. festuca ovina is a grass species adapted to azerbaijan region climate,iran. this species is a valuable source for forage production and soil conservation.nitrogen (n), phosphorus (p) and potassium (k) are three most important plant nutrients.the aims of present study were to investigate the effects of ...
