Synthesis of cyclohexane derivatives including Br, Cl, N, O, and S at 1,2,4,5-positions: selectivity in addition reactions
(Pergamon-Elsevier Science Ltd, 2014)
Brominations of mono addition products of 1,4-cyclohexadiene with 2,4-dinitrobenzenesulfenyl chloride (RSCI) selectively gave 1R(S),2R(S),4R(S),5R(S)-4,5-dibromo-2-(2,4-dinitrophenylthio)cyclohexyl acetate and 1R(S),2R(S ...
Safety and Effectiveness of 5-mm and 10-mm Electrothermal Bipolar Vessel Sealers (LigaSure) in Laparoscopic Resections for Sigmoid Colon and Rectal Cancers
(Mary Ann Liebert, Inc, 2012)
Background: LigaSure (TM) (Covidien, Mansfield, MA) has been used in cases undergoing laparoscopic colon and rectal resections. This study aims to analyze the efficacy and safety of the 5-mm and 10-mm devices. Subjects and ...
Automated Model Updating Effect on the Linear and Nonlinear Dynamic Responses of Historical Masonry Structures
(Springer, 2018)
Finite element models supply the simulation of the problems to obtain the structural behaviors under different loading conditions. The updating processes based on changing the uncertain parameters such as material properties, ...
Estimation of the temperature profiles of reinforced concrete cross sections exposed to standard fires by using artificial neural networks with different topologies
(Wiley, 2016)
The thermal analysis in structural members can be extremely complex, especially for materials that retain moisture and have a low thermal conductivity. The simplest method of defining the temperature profile through the ...
Effectiveness of Black Mulberry Molasses in Prevention of Radiotherapy-Induced Oral Mucositis: A Randomized Controlled Study in Head and Neck Cancer Patients
(Mary Ann Liebert, Inc, 2017)
Objectives: Radiation-induced oral mucositis is one of the problems experienced by 70%-80% of patients receiving radiation therapy (RT). This randomized controlled trial assessed the effectiveness of black mulberry molasses ...
The effects of chemical attacks on physical and mechanical properties of concrete produced under cold weather conditions
(Elsevier Sci Ltd, 2014)
This study investigates the effects of corrosive conditions on the physical and mechanical properties of concrete produced in cold weather. 30% calcium nitrate and 5% hydroxyethylaminemixture (HEA) were used as additives ...
Investigation of freeze-thaw effects on mechanical properties of fiber reinforced cement mortars
(Elsevier Sci Ltd, 2014)
Fibers are used for improving some properties of conventional concrete (which is a brittle material) such as tensile strength, abrasion resistance, absorption and crack control. This study investigates the usability of ...
The effects of antifreeze use on physical and mechanical properties of concrete produced in cold weather
(Elsevier Sci Ltd, 2013)
This study examined the effects of antifreeze on the physical and mechanical properties of the concrete which are produced in cold weather. 30% Calcium Nitrate and 5% hydroxyethylaminemixture (HEA), Calcium Nitrate (KN) ...
Sensitivity-Based Model Updating of Building Frames using Modal Test Data
(Korean Society of Civil Engineers-Ksce, 2018)
Model updating is of significant importance in the actual analyses of real structures. The differences between experimental and numerical dynamic characteristics can be minimized by means of this procedure. This procedure ...
Strength and ultrasonic properties of cemented paste backfill
(Elsevier, 2014)
This paper presents the strength (UCS) and ultrasonic pulse velocity (UPV) properties of cemented paste backfill (CPB) produced from two different mill tailings (Tailings T1 and T2). A total of 240 CPB samples with diameter ...
