Asymptotically spectral periodic differential operators
(MAIK Nauka/Interperiodica, 2018-09)In this paper, we investigate spectral expansion for the asymptotically spectral differential operators generated in L2m (−∞,∞) by ordinary differential expressions of arbitrary order with periodic matrix-valued coefficients. -
Characterization of the damage mechanism of composites against low velocity ballistic impact using computed tomography (CT) techniques
(Crimson Publishers, 2017-10-23)Low velocity impact damages are particularly considered as risky and dangerous since the detection of the damage from the surface is almost impossible for extensive evaluation. The mechanisms of penetration and damage for ... -
A cobalt arylphosphonate MOF – superior stability, sorption and magnetism
(Royal Society of Chemistry, 2019-01)We report a novel metal-organic framework (MOF) based on a cobalt arylphosphonate, namely, [Co2(H4-MTPPA)]·3NMP·H2O (1·3NMP·H2O), which was prepared solvothermically from the tetrahedral linker tetraphenylmethane ... -
Computational fluid dynamics of developing avian outflow tract heart valves
(Springer, 2012-10)Hemodynamic forces play an important role in sculpting the embryonic heart and its valves. Alteration of blood flow patterns through the hearts of embryonic animal models lead to malformations that resemble some clinical ... -
Control of the flow past a sphere near a flat wall using passive jet
(Elsevier, 2019)In the present investigation, interactions between the vortices shedding from a single sphere and the boundary layer flow over a flat plate with various gap ratios have been investigated at Re = 5000 using the techniques ... -
Development of antimicrobial and water repellent/ hydrophobic (easy-cleaning) properties on cotton fabrics using nanocoating processes
(Scitechnol, 2017)Recently, there has been considerable interest in doing research and development on functional nano coated textiles and in creating innovative textile products. Studies have been continued for developing innovative high ... -
Development of tubular woven preform reinforced composite pipe and comparison of its compression behavior with filament wound composite
(Ege Üniversitesi, 2019)In this research a novel preform for the reinforcement of tubular composite structures has been developed. The mentioned preform was woven from para aramid yarn in the tubular form. A mandrel was passed through a certain ... -
DFT and semi-empirical analyses of Cr-3(+) and Fe3+ impurity centers in Cs2NaYF6: Microscopic insight into structural properties
(Elsevier, 2019)A detailed microscopic study of the local geometry was performed for the cation sites in fluoroelpasolite Cs2NaYF6 crystal doped with 3d ions (Cr3+ and Fe3+). Electronic structure of pure, Crdoped and Fe-doped Cs2NaYF6 has ... -
Dynamic stress intensity factors for suddenly loaded structures using enriched finite elements
(Elsevier, 2014-04)In this paper, an efficient finite element formulation for stationary cracks subjected to dynamic impact loading is presented. For impact problems, where wave propagation effects dominate, the onset of rapid crack growth ... -
Effects of heat treatment on the mechanical properties of the vanadis 4 extra and vanadis 10 tool steels
(OMICS International, 2017)Vanadis tool steels which are a trademark of the Uddeholm AB Company are high vanadium content (along with chromium and molybdenum) steels with unique mechanical properties such as very high wear resistance along with a ... -
An ex-ovo chicken embryo culture system suitable for imaging and microsurgery applications
(MYJoVE Corporation, 2010-10)Understanding the relationships between genetic and microenvironmental factors that drive normal and malformed embryonic development is fundamental for discovering new therapeutic strategies. Advancements in imaging ... -
Experimental and numerical investigation of a longfin inshore squid's flow characteristics
(Isfahan University Technology, 2017-01)In the present study, a three-dimensional numerical squid model was generated from a computed tomography images of a longfin inshore squid to investigate fluid flow characteristics around the squid. The three-dimensional ... -
Femtosecond laser photodisruption of vitelline vessels of avian embryos as a technique to study embryonic vascular remodeling
(SAGE Publications, 2014-12)During cardiogenesis, congenital heart defects (CHDs), generally start as local tissue abnormalities without underlying genetic causes, suggesting abnormal hemodynamics may be an important source. Due to the scarcity of ... -
Functional honeycomb based composite panels for structural and thermal management applications
(OMICS International, 2017)This study deals with the functional properties of honeycomb panels for structural applications, thermal management and sound/heat insulation to design more eco-friendly products. Using honeycomb panels filled with ... -
A generic transformation of advanced materials technologies: towards more integrated multi-materials systems via customized R&D and innovation
(Elsevier, 2015)Starting with the last quarter of the 19th century until recent modern times, rapidly accelerating technological transformations and developments result in better and superior materials and cause improvements in almost ... -
Growth and hemodynamics after early embryonic aortic arch occlusion
(Springer, 2015-08)The majority of severe clinically significant forms of congenital heart disease (CHD) are associated with great artery lesions, including hypoplastic, double, right or interrupted aortic arch morphologies. While fetal and ... -
Hemodynamic patterning of the avian atrioventricular valve
(Wiley, 2011-01)In this study, we develop an innovative approach to rigorously quantify the evolving hemodynamic environment of the atrioventricular (AV) canal of avian embryos. Ultrasound generated velocity profiles were imported into ... -
Influence of TiC, TiN and TiC(N) additions on sintering and mechanical properties of injection moulded titanium based metal matrix composites
(Maney Publishing, 2014-03)Titanium (Ti) matrix composites based on Ti and reinforced with TiN, TiC and TiCN particles, were processed following a powder injection molding route: mixing, preparation of feedstock, moulding, debinding and sintering ... -
Investigation of mechanical behavior of polymer encapsulated liquid crystal composites
(IOP Publishing, 2019)In this study, the mechanical properties of polymer-liquid crystal composite films have been investigated as a function of changing polymer concentration. Nematic liquid crystal was encapsulated in waterborne polymer matrix ... -
