For this purpose the Allium test was carried out exposing roots to spirotetramat for 24 and 48 hours at the concentrations of 1 mL/L, 2 mL/L, 4 mL/L. After the spirotetramat applications, root tips have been harvested and standard mitotic test procedures have been realized. The mitotic index was calculated as the number of dividing cells per number of 1000 1500 observed cells and the chromosomal aberrations also were scored for each group. Our results have showed that the mitotic index significantly decreased with the increase of doses and exposure times when compare to their controls. According to our results, MI value has been decreased as 56% and 65% in 4 mL/L spirotetramat application after 24 and 48 hours respectively. As a result of our research, it was understood that the chromosomal aberration frequency increased in all application groups when we compare with the control group. According to chromosomal aberration frequency results, when we compare with control group chromosome aberration frequency increased approximately seven fold in 4 mL/L spirotetramat applications after 24 and 48 hours respectively. Our results showed that spirotetramat induced significant increases of chromosomal aberrations such as table and pole shifting, chromosomal bridge. In addition that mitotic index (MI) decreased significantly with increasing of spirotetramat doses and the exposure time as compared to their controls.

In addition, during the survey, the height and weight of the participants were determined and the body mass index values were calculated. The drinking habits of rural and central district students participating in the study were 35% in the evenings for rural girls and 48% for boys (p=0.211); the central region was found to be 55% in girls and 59% in boys (p=0.282). While 20.62% of the children in the families participating in the survey liked hot milk, 23.5% liked cold milk, 29.4% stated that they liked to drink milk with fruit.

In addition to 25 Polycythemia vera and 25 Essential thrombocytosis cases who received bone marrow biopsies with the diagnoses of Polycythemia vera and Essential thrombocytosis, 25 normocellular bone marrow biopsies were included as the control group. In cells belonging to erythroid, myeloid and megakaryocytic series in the bone marrow biopsies of the cases, Wnt 1, β catenin and E cadherin expressions were examined by the immunohistochemical method. For each series, staining up to 10% was accepted as negative, and 10% and higher staining was accepted as positive. In the Essential thrombocytosis cases, there was a significant increase in the Wnt 1 expression in the megakaryocytic series and E cadherin expression in the erythroid series (p<0.05). When the cases were assessed within themselves based on the three series, an increase in E cadherin and E cadherin expression in the erythroid series in the Polycythemia vera cases and Wnt 1 expression in the megakaryocytic series in the Essential thrombocytosis cases was observed (p<0.05). β catenin expression was not encountered in the cases. Consequently, it was considered that Wnt 1 may be associated with megakaryocytopoiesis in ET cases, and E cadherin may be associated with erythropoiesis in ET cases. However, it will be beneficial to repeat the study on broader myeloproliferative neoplasm series and assess other factors in the Wnt pathway.

For this purpose, the engineering geological properties and excavatability classification of rocks around the Haroglu Mountain located in the northeast of Baskil in Elazig were studied. The research started with a desktop study and then continued with a walkover, the determination, and mapping of lithostratigraphic units outcropping in this study area. Yuksekova Formation, Kuscular Formation, Seske Formation, Kirkgecit Formation, and surficial deposits are the lithostratigraphic units in order of occurrence from old to young. Yuksekova Formation, the oldest unit between them, makes up of a group of plutonic, hypabyssal, volcanic, and pyroclastic rocks. After Yuksekova Formation occurs which is magmatic, the sedimentary sequence begins to form with Middle Paleocene-aged rocks. Sedimentary rocks are divided into three formations according to their stratigraphic properties. In order of occurrence from old to young, these sedimentary formations are composed of Kuscular conglomerate, Seske Formation, Kirkgecit Formation. Also, surficial deposits as the youngest unit are formed occasionally over other formations. The structural geological properties of the formations, one of the most important parameters of the excavability, were mapped. The set number, roughness, magnitude of the angle of dip, azimuth of strike or dip of discontinuities or joints, and the block volume are the significant parameters that are influenced excavatability. The azimuths of strikes of discontinuities were measured and carried out the rose diagrams from them. As a result of these measurements, the discontinuities or fractures in Yuksekova Formation have been usually found in the azimuth of a strike having NNE and a 45-90 SW of angle and azimuth of dip. It was determined that the orientation of K60W of excavation is the orientation of a very favorable excavation based on the discontinuity attitudes in the study area. It was established that the orientation of a very unfavorable excavation also is in the azimuth of the strike of fracture, namely N30E. Excavatability of the rocks was determined by assessment of lower and upper discontinuity spacing index and point load strength values. Yuksekova Formation requires methods that can be excavated from very hard to extremely hard ripping (D 9)–blasting by taking into consideration formations exposed in the study area. Kuscular Formation can be excavated by methods of easy ripping (D 6-D 7) to hard ripping (D 8) and Seske Formation also easy ripping (D 6-D 7)-very hard ripping (D 9). Kirkgecit Formation has the capabilities of being excavated by methods of hard digging (CAT 245) to very hard ripping (D 9).

Diclofenac Sodium is a potent Non-Steroidal Anti-Inflammatory Drug (NSAID) commonly used as an Over the Counter (OTC) drug. Potency determination was performed to evaluate and authenticate whether the marketed samples complies with the declared specification. In vitro dissolution study was, performed to verify the potency of the drug and its relative bioavailability. Hardness was checked to verify whether it interferes with the dissolution, which might ultimately affect the drug bioavailability. In this present study, a simple, cost effective, and spectrophotometric method for the potency determination of marketed diclofenac sodium tablets is used. Six samples were randomly collected from the market and coded as A, B, C, D, E and F, and the potency determined are 80%, 98.7%, 126.9%, 99.6%, 109.2% and 91.4% respectively.

To examine this relationship for the period of 1987 2017, the variables of the public final consumption expenditures, the modern sector share, the inflation and the human capitalare also added to the model setted as control variables, and the long term relationships among the variables are analyzed by using the ARDL (The Autoregressive Distributed Lag) Boundary Test approach. Empirical evidence refers to the validity of the Financial Kuznets Curve Hypothesis in Turkey, in other words, there is an inverse U shaped relationship between the financial development and the income inequality. Accordingly, while the financial development raises the inequality in income distribution to a certain threshold level, it reduces the inequality after this threshold level in Turkey. Moreover, in the long run increases in the modern sector share, the public final consumption expenditures and in the trade openness help to reducing income inequality but increases in the inflation and in the human capital make worse income inequality.
