در این تحقیق، تأثیر فراصوت و ریزپوشانی کردن بر ویزگیهای کمی و کیفی ترکیبات زیست فعال عصارۀ استخراج شده از تفاله انگور رقم رشه سردشت بررسی شدهاست. برای بررسی تأثیر شدت و زمان فرایند فراصوۀ از روش سطح پاسخ استفاده شد. متغیرهای مستقل شامل شدت فراصوت و زمان فرایند به ترتیب در سه سطح 20، 60 و 100 درصد و 5، 10 و 15 دقیقه…
Eight pendant boranes are better than one for the activation of Lewis bases. A new diphosphine ligand that features four pendant borane groups has been prepared. The coordination chemistry of this new scaffold has been established using nickel—giving an octaboraneyl Ni0 complex; this species reacts readily with Lewis…
The Elymaean have existed as a semi-autonomous satrap and sometimes autonomous, coinciding with the Seleucids and the Parthians in the southwest and west of Iran. This government has played an active presence in political and economic events of the region from the mid-second century BC to the advent of the Sasanid Emp…
Chemical stabilization is one of the oldest methods of stabilization of problematic soil. In recent days, it has been investigated that addition of fibers will improve the ductility behavior of the soil there by reducing the development of crack during shrinkage. Extensive study has been carried out on the stabilizati…
The ageing and field-forced deageing characteristics of a commercial cobalt-doped BaTiO 3 piezoceramic are reported. It was found that the internal bias field in unpoled specimens reduced according to an exponential time law during field-forced deageing. The time constants associated with the deageing process were 159…
Introduction: Gingival Recessions (GR) are understood as processes of apical migration of periodontal tissues in relation to the cement-enamel junction, that is, they result in an inadequate positioning of the periodontium of protection, causing the consequent root exposure of the dental elements involved. Objective:…
The electrical resistivity and the thermoelectric power of liquid metal Cs have been theoretically investigated using the muffin-tin potential approach with the help of an accurate experimentally measured structure factor, S(q), and radial distribution function, g(r) measured along the liquid–vapour coexistence curve.…
Easy-Synthesis of BDA/ABDA Functionalized Hydrophilic Superparamagnetic Iron Oxide Nanoparticles for Magnetic-Hyperthermia Application
Aircraft structures experience various kinds of loads over their entire\nlifetime, typically leading to fatigue and ultimately structural failure. In\norder to avoid structural failure during operation, the maximum number of\nflight cycles and flight hours is regulated by laws ensuring continued\nairworthiness. Howeve…
Zusammenfassung Kunststoffe sind allgegenwärtig und werden in allen aquatischen Umweltkompartimenten den Meeren, in Flüssen, an Stränden, den Sedimenten und in der gesamten Wassersäule und auch innerhalb von Biota gefunden. Durch dessen Zerfall entstehen kleinere Bruchstücke, die unter den Begriff Mikroplastik (MP) fa…
The butyrylchitin filaments were manufactured as follows: dry-spun fibers were obtained by spinning from a 23% solution of butyrylchitin in acetone into air. The lattice corresponded to the orthorhombic crystallo-graphic system. However, it should be emphasized that there was a difference in the lattice unit cells bet…
The methods and requirements necessary to perform accurate and reproducible polarisation-field (P-E) measurements are discussed. An introduction to P-E measurements is given outlining the electrical origins of the P-E loop and visual interpretation of loop characteristics. Conventional and computer based measurement s…
Third-party damage is unauthorized right-of-way encroachment and activities near a pipeline that accidentally strikes, damages, or ruptures a pipeline. Third-party activity has always been, and remains to this day, a threat to the integrity of a pipeline and the primary cause of major failures of pipelines. Population…
Al–6.5Ni–1.5Fe (ağ.) ötektik bileşiminde hazırlanan alaşım sabit katılaştırma hızında (V = 16.57 µm/s) ve beş farklı sıcaklık gradyentinde (G = 3.23–8.52 K/mm) Bridgman Tipi fırın yardımıyla kontrollü doğrusal katılaştırılarak sıcaklık gradyentinin (G) alaşımın mikroyapı (λ) ve mikrosertlik (HV) özelliklerine etkisi a…
The textile industry is currently moving towards to the fourth Industrial Technological Revolution. One of the applications of the industrial revolution 4.0 is in the field of computational physics. The application of applied physics especially computational physics on textile science can be initiated in analyzing the…
In this work, we treat the rotation of the optical axis as a new degree of freedom and theoretically propose a tilted linear-crossing metamaterials (TLCMM). Specifically, the conical dispersions of the NLCMM and TLCMM have the same shapes as type-I and type-II Dirac cones, respectively, in condensed matter physics. Up…
The paper is concerned with the P—E (polarisation—electric field) switching behaviour of hard PZT (lead zirconate titanate) ceramics. The remanent polarisation P r , saturation polarisation P s , and internal bias field E i were determined at a field amplitude of 3.5 kV mm -1 during ageing and field-driven deaging mea…
This study investigated the effect of organic alternative scouring agents on structure of cotton/polyester blend fabric. A structural modification for a cellulose/polyester blend has been carried out using (COOH)2, CH3COOH and CH3CH2OH alternative scouring agents and NaOH was used as control. The scoured fabrics were…
We study the dynamic wetting of a self-propelled viscous droplet using the time-dependent lubrication equation on a conical-shaped substrate for different cone radii, cone angles and slip lengths. The droplet velocity is found to increase with the cone angle and the slip length, but decrease with the cone radius. We s…
The basic problems of the theory such as principle of assigning classes of fire resistance, reliability issues, alternative approach to calculation methods, mathematical models of concrete and reinforcement deformation diagram, numerical modelling techniques, temperature analysis and calculation of mechanical work of…
