Inquiry based experimental applications in the chemistry laboratory [Aplicaciones basadas en la indagación en el laboratorio de química]
(2015)
In the study, pre-service chemistry students' performance that appears after applications in which they developed inquiry based chemistry experiments has been examined. Also examined was whether inquiry based experimental ...
Experimental investigation the effects of mixture impoverished on the specific fuel consumption, engine performance and exhaust emissions a pre-combustion chamber gasoline engine
(2015)
In this study were investigation of the effect on exhaust gas emissions and the power cycle parameters change of changing the number of injector holes in pre-chamber a gasoline engine. In study 1, 2 and 3- hole injector ...
An Inexpensive and Sensitive Method for Speciative Determination of Sn(IV), Sn(II), and Total Sn as Sn(IV) in Selected Beverages by Micellar Improved Spectrophotometry
(2015)
In the present study, an inexpensive, selective, and micellar sensitive spectrophotometric method for Sn(IV) was developed at 537 nm. The method is based on the formation of ternary complex of Sn(IV) with tartaric acid and ...
Microstructural evaluation and characterization of solid-state reaction of B<inf>2</inf>O<inf>3</inf> doped BaZrxTi<inf>1-x</inf>O<inf>3</inf> ceramics
(2015)
0.5 wt. % B<inf>2</inf>O<inf>3</inf> doped BaZrxTi<inf>1-x</inf>O<inf>3</inf> ceramics (x = 0, 0.1, 0.2, 0.3, 0.4) were synthesized by adapting the solid-state synthesis method. B2O3 used as a sintering additive in the BT ...
Examination of Turkish women sociologically in relation to gender apartheid depending on statistical data
(2015)
In this study, we observe that Turkish women differ from other developed world countries in terms of demographic features. In Turkey where particularly gender apartheid is being experienced, there are some facts such as ...
Determination of total Sn in some canned beverages by FAAS after separation and preconcentration
(2015)
A micelle-mediated preconcentration method has been developed for determination of trace amounts of tin in canned beverage samples, which is widely used in food industry for packing, but its utilization is limited due to ...
Effect of educational on symptom control and quality of life on asthmatic patients [Astimli hastalarda eğitimin semptom kontrolüne ve yaşam kalitesine etkisi]
(2015)
The aim of this study was to determine the effects of education on symptom control, exacerbation frequency and quality of life in asthma patients. The study which was randomize experiment and control was conducted 1 March ...
On continuity of soft mappings
(2015)
In this paper, we give some new characterizations of soft continuity, soft openness and soft closedness of soft mappings. We study restriction of a soft mapping and generalize the pasting lemma to the soft topological ...
Relationship between packed cell volume levels and serum nitric oxide concentrations in cattle with tropical theileriosis
(2015)
This study was performed to determine changes in serum NO (nitric oxide) levels in cattle with theileriosis in accordance with PCV levels. For this purpose, 42 cattle with theileriosis and 10 healthy cattle have been used ...
Development of a simple, sensitive and inexpensive ion-pairing cloud point extraction approach for the determination of trace inorganic arsenic species in spring water, beverage and rice samples by UV-Vis spectrophotometry
(2015)
The determination of inorganic arsenic species in water, beverages and foods become crucial in recent years, because arsenic species are considered carcinogenic and found at high concentrations in the samples. This ...
