A Research On The Vegetation Structures Of The Rangelands Of District Tufanbeyli, Adana = Adana İli Tufanbeyli İlçesi Meralarının Vejetasyon Yapısı Üzerine Bir Araştırma

Selahattin ÇINAR

This research was conducted to determine vegetation structures of the upland rangelands in the five villages of Tufanbeyli district, Adana, in 2010. Vegetations of the rangelands were studied by the loop method. In the study, plant cover percentages, botanical compositions based on the cover percentage in the plant covered area, range quality values and range conditions of the rangelands studied were determined. Average percentages of grasses, legumes and other family plants in the total plant cover were determined as 36.9 %, 22.0 % and 41.1 %, respectively. It was determined that the averaged ...More

The investigation of the use of plant-based wild mustard and boron doped oil as engine lubrication oil in diesel engines

Hüseyin ÖĞÜT

In internal combustion engines, mineral engine oils which serve as lubricants between parts are not used alone due to technical reasons and various additives are made use of for better lubrication. In these additives, liquid boron serves to reduce friction. To reduce the environmental damage caused by engine lubrication oils, it is necessary to improve the properties of biological oils so that they can be used and compete with mineral oils technically. In the study, the use of liquid boron as an engine lubrication oil additive, together with wild mustard oil methyl ester, was investigated. Two ...More

Abiotic stress-induced regulation of antioxidant genes in different Arabidopsis ecotypes: microarray data evaluation

İbrahim İlker ÖZYİĞİT

Although stresses induce generation of reactive oxygen species (ROS), which are highly reactive and toxic, and cause severe damage to cellular components; plants have very efficient enzymatic ROS-scavenging mechanisms. Despite the substantial knowledge produced about these enzymes, we still have limited knowledge regarding their expression patterns in relation to the stress type, duration and strength. Thus, taking advantage of microarray data, this work evaluated the abiotic stresses (salt, cold, heat and light) induced regulation of six antioxidant enzymes, superoxide dismutase (SOD), catala ...More

The effects of the use of vegetable oil based as engine lubrication oil on engine performance and emissions in diesel engines

Hüseyin ÖĞÜT

The boron occupies an important place on contributions and its usage is getting widespread. Although the use of boron-added mineral oils serves to reduce friction, environmental risks can not be totally removed. It is necessary to improve the properties of biological oils used for additives so that they can compete with mineral oils technically. In the study, the use of liquid boron as an additive for engine lubrication oil together with vegetable oil was investigated experimentally in two diesel engines. Experiments were first carried out using mineral lubrication oil in the engine, and then ...More

A MACROSCOPIC STUDY ON THE MUSCLES AND TENDONS OF FOREPAWS IN THE ANATOLIAN BOBCAT (Lynx lynx)

Hasan Hüseyin ARI

This study was performed on the tendons and muscles of two Anatolian bobcats (Lynx lynx). The research materials were donated by Republic of Turkey Ministry of the Forestry and Water Affairs Sivas Branch Manager. To achieve this objective, dissection and radiography were applied to two dead specimens. Digit I is radiographically rudimentary in the forepaw. The muscles and tendons of the forepaw in the bobcat are located in the cranial and caudal aspect of the antebrachium, the central manus and hypothenar region. The extensor muscles are situated on the cranial aspect of the antebrachium, whil ...More
