Maden, Nafiz; Afsin, Mustafa; Aksever, Fatma; Davraz, Aysen; Biswas, A; Sharma, SP
The Hudai-Sandikli geothermal basin having 23 thermal productivity wells is a significant geothermal energy source field. The analysis of power spectrum, conventional heat flow and silica heat flow methods were implemented to identify the geothermal waters circulation depth, depth to Curie point and surface heat flow rate in the Hudai-Sandikli geothermal field. Hydrogeochemical facies of geothermal immature ancient waters having deep circulation in lower hydraulic conductive aquifers are Na-Ca-HCO3-SO4 and Na-Ca-SO4-HCO3, which is represented very high ion content because of extensive contact with rocks. The heat conduction law is employed to specify the rate of heat flow using the geothermal gradient value. The numerical results determined from silica geothermometer method, the mean heat flow density and Curie temperature depth are obtained as 103.69 mWm(-2) and 11.81 km, respectively. The study region was represented by a mean geothermal gradient of 49.18 degrees C km(-1) yielding average reservoir depths of 0.90 km. The estimated Curie temperature, heat flow, reservoir temperature values demonstrated that the region indicates significant geothermal energy potential because of the partial melting of lithospheric crust.

The goal of this study was to determine some physicochemical and microbiological properties of Erzurum butter. Random samples (n = 30) were collected from different retail markets throughout Erzurum province. The pH, acidity, and melting point values of samples were 3.88, 0.47%, and 30.03 degrees C, respectively. The salt, fat, and moisture values of some samples (sample no 1, 14, and 18) were not harmony with Turkish Food Codex. The highest and lowest peroxide, iodine, saponification, Reichert-Meissl (RM), and Polenske values were found to be in the range of 0-0.51 mEqO2/kg, 22.97-38.64, 195.45-228.54, 17.08-30.-56, and 0.72-1.80, respectively. The refractive index value (RI) was changed from 1.4591 to 1.4620. Total coliforms, aerobic mesophilic bacteria (TAMB), lactic acid bacteria (cultured in MRS and M17), and mould and yeasts mean counts were 1.07 log CFU g-1, 6.79 log CFU g-1, 6.45 log CFU g-1, 6.76 log CFU g-1, and 5.33 log CFU g-1, respectively. There were high differences in physicochemical and microbiological properties of butter might be attributed to a non-standard production process as well as non-standard raw material. In sum, the sanitation and storage conditions should be improved from production to consumption to improve the butter quality.

Enriched in flavonoid compounds, phenol acids, and terpene derivatives, propolis has been shown to regulate apoptosis signaling pathways and alter the expression of microRNAs (miRNAs). In the present study, it has been aimed to examine the effects of Turkish propolis on miRNA levels of breast cancer (MCF-7) cells, and its relationship with cell proliferation and apoptosis. Cytotoxic activity of ethanolic propolis extract (EEP) was evaluated using MTT assay. Mechanisms involved in the cytotoxic action of Turkish propolis in MCF-7 cells were investigated with regard to apoptosis and cell cycle using flow cytometry and western blot. Mitochondrial membrane potential (MMP) were evaluated by spectrofluorometric method. miRNA levels were detected by qRT-PCR method. EEP exhibited selective toxicity against MCF-7 cells compared to normal fibroblast cells. EEP increased the cell cycle arrest at the G1 phase. EEP elevated the apoptotic cell death through increasing pro-apoptotic protein levels (p21, Bax, p53, p53-Ser46, and p53-Ser15), decreasing MMP and altering the expression levels of specific tumor suppressors (miR-34, miR-15a, and miR-16-5p) and oncogenic (miR-21) miRNAs. These data support that Turkish propolis may be evaluated as a potential natural agent for new anticancer drugs in future.
- MakaleYalnız künye2020Determination of geological structures by geophysical and geotechnical techniques in Kırklartepe Dam Site (Turkey)
Sari, Mahmut; Seren, Aysel; Alemdag, Selcuk
In foundation research of engineering structures, application of geophysics methods before drilling work allows not only more economical studies but also a more detailed determination of underground sections. Especially in pre-feasibility studies on long tunnel routes, dam sites and lake areas, it has a vital importance in terms of structural safety to determine possible underground buried fault lines, lithology changes, anticlinal-synclinal structures and underground openings. By considering these effective factors, the alluvium/bedrock border and the positions of potential buried faults in the dam site and lake area in the Kırklartepe area of the province of Bayburt in northeastern Turkey were determined by comparison with geophysical and geotechnical methods. First of all, the resistivity of the dam axis location and the change of the Vp wave velocity by depth were determined by comparing the results between geophysical methods of electrical resistivity tomography (ERT) and seismic refraction tomography (SRT), respectively. Afterwards, from the foundation boreholes opened in the dam axis location, joint frequency and the other parameters determined by observations were obtained. With these parameters, 2-dimensional zoning profiles of the dam axis location were formed, and the alluvium-bedrock border and the locations of the buried faults were determined. Two potential faults in the NW-SE direction relative to the location of the dam axis were clearly revealed in the zoning profiles obtained in the ERT and SRT measurements. Additionally, the presence of these faults was determined as a result of examining the separation and joint frequency parameters from the drilling core samples collected from the BH_3 and BH_5 boreholes opened in the investigated area based on changes in the vertical and horizontal directions. In addition to these, in the ERT study, two potential faults other than the determined two were also detected. It was seen in the zoning profiles that these faults corresponded to right under the BH_2 borehole and 60 m SW of the BH_6 drilling. Consequently, in the zoning studies conducted at the examined site, the change in the lithology at the dam axis by depth (alluvium-bedrock border), lateral correlations of boreholes and potential faults were determined. It was recommended for the selected dam axis location to be constructed at a more suitable place in the NW direction in terms of engineering. Furthermore, with this study, it was revealed once again that it is highly essential to use geophysical and geotechnical together in conceptualizing large engineering structure projects.

Sirat, Abdulveli; Bahar, Bilge
This study aimed to select stable cultivars in terms of desired agronomic or quality criteria from among 15 two rowed barley cultivars that may remain stable in varying year conditions during 2014-2015 and 2015-2016. Furthermore, relationships among these traits were investigated. Some agronomical and quality traits of barley were affected by years and cultivars. Yield, yield components and some quality parameters were affected by the cultivars. Also, days to ripening was affected by years, cultivars, and year x cultivar interaction. Crude protein content (CPC) was significantly positive correlated with ASH during both seasons. Starch ratio (SR) showed significantly negative correlations with ASH and CPC during both seasons. ADF and NDF had significant positive strong correlation with one another and ASH during both years while they showed significant negative correlations with SR. The results show that technological properties are not affected by the interaction of cultivar x year; therefore, these stable cultivars can be readily used in malt or feed technology if their technological features are considered. For example, cv. Unver contained low ratios of ash, CPC, oil, soluble fiber and high SR in the malt industry; cv. Hasat which includes the opposite technological properties of cv. Unver, was found be suitable for use in feed technology.
- MakaleAçık Erişim2020SOS5 gene-abscisic acid crosstalk and their interaction with antioxidant system in Arabidopsis thaliana under salt stress
Acet, Tuba; Kadıoğlu, Asım
SOS5 locus, encodes cell wall adhesion protein under salt stress conditions in plants, and it is required for normal cell expansion as well as for sustaining cell wall integrity and structure. However, it is still unknown how this gene locus-ABA cross-talk and interacts with the antioxidant mechanism under salt stress conditions. For this purpose, the study focused on mutant sos5-1 plant treated with ABA under NaCl stress and observed its growth and development as well as stomatal aperture, lipid peroxidation, proline, hydrogen peroxide (H2O2) and ABA contents, and some antioxidant enzyme activities. In addition, the expression levels of ABA related genes have been analysed by RT-PCR after stress application. According to findings, sos5-1 mutant plants treated with ABA under salt stress resulted in eliminated cellular damage compared to those which are solely exposed to salt stress; other observations include closing of stomata, decreased H2O2 content, increased amount of proline, and similarity with the wild type due to induced antioxidant enzyme activities. Besides, both ABA biosynthetic and inducible gene expressions of the mutant plant under salt stress were lower compared to the control, and catabolism gene expression was higher. As a result, SOS5 gene in synergy with ABA, scavenge the ROS by stimulating antioxidant system, leads to an increase in stress related gene expressions and thus contributes to salinity tolerance. This study is significant in the way that it shows how SOS5 gene locus, under salt stress conditions, interacts with antioxidant system in sustaining cell wall integrity.

The aim of this study is to help to create a healthier environment by measuring the noise levels in the furniture and lumber sectors of forest products industry. In this study, noise measurement for approximately 3 min has been conducted in 4 measurement spots in the side of the machinery, in the factory entrance and in full and empty state for each machinery; from 3 different chosen spots in enterprises producing lumber. Measurements have been recorded as 720, from each machine as 36 measurements, with the condition to be recorded every 5 sec for 3 min. For this purpose, noise measurements have been carried out in 17 workplaces producing lumber and results have been compared statistically. As a result of the obtained findings, it is understood that the noise levels of thickness machinery don't exceed the value for the upper limit stated in the regulations. However, vertical wood band sawmill and band saw machines have been observed to go over this limit. Besides, some factors of planning and multi slitting machine don't exceed this limit, some of them exceed. As a result, it has been conducted that when noise levels of machinery used in the lumber industry enterprises exceed the upper limit stated in the regulations, they can pose a serious threat to human health.

Ulukavak, Mustafa; Yalçınkaya, Mualla; Kayıkçı, Emine Tanır; Öztürk, Serkan; Kandemir, Raif; Karslı, Hakan
In this work, a relationship between ionospheric TEC anomalies and different earthquake magnitude groups before the main shocks was investigated. For this purpose, 2942 global earthquakes with Mw≥6 from 2000 to 2019 and possible ionospheric TEC anomalies that occurred before earthquakes were examined by considering 13 different index values of space weather conditions (geomagnetic storm indices and solar activity indices). Anomalies of ionospheric TEC changes were defined for 15-days before and 4-days after the earthquakes by using 15-days moving median method with the length of 15 days. Earthquakes were first grouped according to their magnitudes, and then negative and positive TEC anomalies in quiet days before the earthquakes were detected. These anomalies were observed as ∼5–13, ∼5-10, ∼5-15, ∼3-13, ∼7-15, ∼1 and ∼5-8 days ago for the earthquakes of 6.0 ≤ Mw<6.5, 6.5 ≤ Mw<7.0, 7.0 ≤ Mw<7.5, 7.5 ≤ Mw<8.0, 8.0 ≤ Mw<8.5, 8.5 ≤ Mw<9.0, and 9.0 ≤ Mw<9.5, respectively. Mean of changes in TEC anomalies of these groups is 44.2 % TECU and we detected that the number of positive anomalies in each group is larger than the number of negative anomalies. Consequently, these analyses clearly show that the day-to-day changes in TEC anomalies may supply significant precursors prior to the global earthquakes (M ≥ 6) in the short-term earthquake prediction for main shocks.
