The effect of outlet location on heat transfer performance in micro pin-fin cooling used for a CPU
(2021)
In this study, the simulation of the coolant flow using micro-pin fins in the CPU
heat sink was numerically presented with ANSYS-Fluent, a Computational Fluid Dynamics
(CFD) program. Four different inlet–outlet configurations ...
Metallurgical and Mechanical Characteristics of Friction Welded Joint of 27 wt.%CrWCI/AISI 1040 Steel
(www.springer.com, 2021)
In this study, metallurgical properties of AISI 1040 steel and high-chromium white cast iron joined using
friction welding process was investigated experimentally. Scanning electron microscopy, optical microscopy, ...
Characterization of mechanically alloyed Fe based and MoNiAl+Al2O3 reinforced composites
(https://www.degruyter.com, 2021)
Fe-MoNiAl-Al2O3 powders were mechanically alloyed by a SPEX type attritor. The Fe based composite samples were reinforced with complex mechanically alloyed Fe-MoNiAl-Al2O3 particles in different ratios and Fe matrix ...
Fixed Points of Proinov E-Contractions
(MDPI-SYMMETRY, 28 May 202)
In this paper, we consider a new type of Proinov contraction on the setting of a symmetrical
abstract structure, more precisely, the metric space. Our goal is to expand on some results from the
literature using admissible ...
Ultrasound-assisted supramolecular solvent dispersive liquid-liquid microextraction for preconcentration and determination of Cr (VI) in waters and total chromium in beverages and vegetables.
(Elsevier, 2021)
Simple, sensitive, selective and green ultrasound assisted supramolecular solvent dispersive liquid-liquid microextraction (UA–SUPRAS-DLLME) method was developed for preconcentration and determination of chromium ions in ...
Modal identification and fatigue behavior of Eynel steel arch highway bridge with calibrated models
(2021)
In this paper, modal parameters of the Eynel steel arch highway bridge are identified and the fatigue behavior of the bridge is investigated. Modal parameters were extracted from three ambient vibration tests carried out ...
Classification of brain tumors from MR images using deep transfer learning
(2021)
Classification of brain tumors is of great importance in medical applications that benefit from computer-aided diagnosis. Misdiagnosis of brain tumor type will both prevent the patient from responding effectively to the ...
Experimental and theoretical investigation for the spectrophotometric determination of thiabendazole in fruit samples
(Elsevier, 2021)
A simple, green, and effective vortex-assisted dispersive liquid–liquid microextraction method was developed for separation, preconcentration and spectrophotometric determination of thiabendazole in fruit samples. This ...
Feasibility of supramolecular nanosized solvent based microsyringe-assisted liquid-phase microextraction for preconcentration and separation of Vitamin B12 from infant formula, food supplement, and dairy products: Spectrophotometric analysis and chemometric optimization
(Elsevier, 2021)
Here, a novel cheap and green analytical method based on supramolecular nanosized solvent based microsyringe-assisted liquid phase microextraction (SS MA LPME) was developed and validated for preconcentration and separation ...
Chemical and biological characterization of sulfated chitosan oligomer as heparin mimics
(Polymers and Polymer Composites, November 2)
In the present study, chitosan oligomer was modified to sulfated chitosan oligomer (ShCsO) to mimic heparin. Its chemical structure was determined by infrared spectroscopy (FT-IR), X-ray diffractometry (XRD), differential ...
