Applicability of friction stir welding to steels
(International OCSCO World Press, 2017)
Purpose: The friction stir welding (FSW) method is widely considered to be one of the most significant developments in joining technology to emerge in the last 30 years. The technique has originally been developed for ...
Microwave-assisted synthesis and biological evaluation of some coumarin hydrazides
(2018)
In this work, 15 different coumarin hydrazides were successfully synthesized and screened for their antioxidant and antilipase activities. To do this, firstly, salicylaldehyde derivatives and Meldrum's Acid were reacted ...
Improvement the wear behavior of low carbon steels by friction stir processing
(Institute of Physics Publishing, 2017)
A low carbon structural steel was surface-hardened by friction stir processing (FSP) through 4 mm thickness from the surface. The hardness of the alloy increased from 140 Hv0.1 to about 240 Hv0.1 after single-pass FSP. ...
Effect of friction stir processing on tribological properties of Al-Si alloys
(Institute of Physics Publishing, 2017)
As-cast Al-12Si alloy was processed by single-pass friction stir processing (FSP), and its effect on mainly friction and wear properties of processed alloy was studied in detail. The needle-shaped eutectic silicon particles ...
A new green protocol for the synthesis of 2-substituted perimidines from hydrazones under catalyst- and solvent-free conditions
(Bulgarian Academy of Sciences, 2018)
A new green protocol was developed for the synthesis of 2-substituted perimidines. The protocol involves a reaction of ethoxy carbonylhydrazone with 1,8-diaminonaphthalene under solvent- and catalyst-free conditions. Simple ...
Formability of friction stir processed low carbon steels used in shipbuilding
(Chinese Society of Metals, 2018)
The stretch formability of a low carbon steel processed by friction stir processing (FSP) was studied under biaxial loading condition applied by a miniaturized Erichsen test. One-pass FSP decreased the ferritic grain size ...

(Cukurova University, Faculty of Medicine, 2019)
Objective: This study aimed to investigate the prevalence of internet addiction among university students and its relationship with sociodemographic variables. Methods: This research, which is practical research, was carried ...
Earthquake knowledge level and sustainable earthquake awareness of university students
(Springer, 2024)
Health professionals have always had essential duties in earthquake events experienced from the past to the present. Possible earthquake expectations make sustainable earthquake awareness and attitudes of students, who are ...
University students’ free time management and quality of life: the mediating role of leisure satisfaction
(BioMed Central Ltd, 2024)
The impact of free time management and leisure satisfaction on quality of life is distinct, however, the role of satisfaction in enhancing quality of life through free time management remains uncertain. Hence, the objective ...
Monitoring of microplastic pollution in sediments along the Çoruh River Basin, NE Türkiye
(Elsevier, 2024)
Microplastic (MP) pollution has become a research issue on the world agenda. Monitoring studies are essential for MP content in aquatic environments since it is the final accumulation point. The present study focused on ...
