Experimental study of the flow between triangular ribs in a square channel
(2016)
An experimental study of the flow features of a channel with triangular ribs was carried out using particle image velocimetry technique. The experiments were performed for three Reynolds numbers, including 2900, 8400 and ...
Sour Orange (Citrus Aurantium L.) Growth is Strongly Mycorrhizal Dependent in Terms of Phosphorus (P) Nutrition Rather than Zinc (Zn)
(2016)
The partial sterilization of soil eliminates useful microorganisms, resulting in the reduced growth of mycorrhizae-dependent citrus plants, which are often unresponsive to the application of fertilizer. Research was conducted ...
Combination of Ultrasonic-Assisted Cloud Point Extraction with Flame AAS for Preconcentration and Determination of Trace Amounts of Silver and Cadmium in Dried Nut and Vegetable Samples
(2016)
In this article, ultrasonic-assisted cloud point extraction (UA-CPE) was used to the preconcentration of trace Ag(I) and Cd(II) in dried nut and vegetable samples. After ion association of Ag(I) and Cd(II) ions with ...
Ultrasound-assisted cloud point extraction of manganese, zinc and tin from digested food samples for their determination by FAAS
(2016)
The current study is focused on the determination of the trace levels of manganese, zinc and tin in wet acid digested foods by flame atomic absorption spectrometry (FAAS) after preconcentration with ultrasound assisted-cloud ...
Catalytic spectrophotometric determination of trace Mo(VI) in milk-based beverages in the presence of bromophenol blue and H2O2 using SDS as a sensitizer
(2016)
A simple and low-cost catalytic spectrophotometric method using sodium dodecyl sulfate (SDS) as a sensitivity-improving surfactant to detect low levels of Mo(vi) in beverage matrices was developed. The method is based on ...
Effects of different organic materials on forage yield and nutrient uptake of silage maize (Zea mays L.)
(2016)
The use of organic materials as a source of nutrients on agricultural lands ameliorates soil physical properties as well as being an environmentally friendly way of disposing of their wastes. This study was conducted to ...
Separation/preconcentration of ultra-trace levels of inorganic Sb and Se from different sample matrices by charge transfer sensitized ion-pairing using ultrasonic-assisted cloud point extraction prior to their speciation and determination by hydride generation AAS
(2016)
In the existing study, a new, simple and low cost process for separation/preconcentration of ultra-trace level of inorganic Sb and Se from natural waters, beverages and foods using ultrasonic-assisted cloud point extraction ...
Measurement and evaluation of hand-arm vibration exposure sourced from some power tools in mining workplaces [Maden işyerlerinde kullanilan bazi iş araçlarindan kaynaklanan el-kol titreşim maruziyetinin ölçümü ve de?erlendirilmesi]
(2016)
This study includes measuring and then evaluating the hand-arm vibration exposure of mine workers. The research is supported by measurements taken from industrial establishments. The measurements were carried out using ...
A preconcentration method for indirect determination of acrylamide from chips, crackers and cereal-based baby foods using flame atomic absorption spectrometry
(2016)
Acrylamide is a toxic species for human health, and is a Maillard reaction product which forms spontaneously in heat treatment process of foods. Therefore, a simple, fast and cost-effective method was developed for the ...
Association of different uncus lesions on magnetic resonance imaging with epilepsy
(2016)
Objective: Uncus is the hook-like most anteromedial portion of the parahippocampal gyrus and is a part of the limbic system. It is the only gyrus, together with the amygdala, that contains nuclei and is associated with ...
