Sezer, İsmet
This study was compiled from the results of various researches performed on using diethyl etheras a fuel or fuel additive in diesel engines. Three different techniques are used for the reductionof the harmful exhaust emissions of diesel engines. The first technique for the reduction ofharmful emissions is improved the combustion by modification of engine design and fuelinjection system, but this process is expensive and time consuming. The second technique is theusing various exhaust gas devices like catalytic converter and diesel particulate filter. However,the use of these devices affects negatively diesel engine performance. The final technique toreduce emissions and also improve diesel engine performance is the use of various alternativefuels or fuel additives. The major pollutants of diesel engines are oxide of nitrogen (NOx) andsmoke or particulate matter (PM). It is very difficult to reduce NOx and PM simultaneously inpractice. Most of the researchers declare that the best way to reduce is the use of variousalternative fuels i.e. natural gas, biogas, biodiesel or using the additives with alternative fuels orconventional diesel fuel. Therefore, it is very important that the results of various studies onalternative fuels or fuel additives are evaluated together to practice applications. Especially, thisstudy focus on the use of diethyl ether in diesel engines as fuel or fuel additive in various dieselengine fuels. This review study investigates the effects of diethyl ether addition on the smokeand PM emissions.

Yildirim, Mehmet Nuri; Yasar, Sekip Sadiye; Karaman, Abdurrahman
The purpose of this study is to determine the effects of the nano-particulate silicon dioxide (SiO2) material on the bending strength and modulus of elasticity in bending of some wood species. Oriental beech (Fagus orientalis L.) and sessile oak (Quercus petrea L.) woods species which are commonly used in the furniture industry were used in this study. Impregnation was carried out with the preparation of SiO2 at concentrations of 1% and 3% according to ASTM-D 1413-76 (1976) standards. According to the results, while solution concentration was increasing in both wood species, total retention (kg/m3) and percentage retention (%) values increased; air dry density (12%), bending strength and modulus of elasticity in bending decreased. The maximum mean values of bending strength and modulus of elasticity was in control samples of oriental beech and the minimum were in sessile oak wood with 3% concentration. These results can be related to the fact that the higher density of oriental beech wood (0.630-0.685 g/cm³). In both species of wood, impregnation with SiO2 resulted loss of about 3-5% in bending strength and 0.6-9% in modulus of elasticity.

Sainfoin (Onobrychis viciifolia) subjected to a range of studies relating to agronomy, environmental preferences, crop protection and plant-microbial interactions, is an important forage species in agriculture, that be prefered by farmers than other forage legumes. This fact has give importance to breeding of this plant for the development of diverse varieties and so for this purpose many wild forms are cultivated. The most important problem in sainfoin cultivation is poor germination problem in wild species. With the aim of solving this problem, we carried out to evaluate the response of wild sainfoin seeds to the application of different gibberellic acid (GA3) (a germination hormone) concentration in vitro conditions. Five levels of gibberellic acid (100, 250, 500, 1000 and 1500 ppm) was used in the test. Seed coat was removed and the seeds were placed on Murashige&Skoog (MS) medium supplemented with gibberellic acid (GA3) and kept under these conditions for 46 days. Seed germination percentage and germination associate parameters; speed of germination, mean germination time, mean daily germination, peak value and germination value, were calculated. The experiment was carried out using complete block design with three replications. According to the results obtained from different GA3 application medium, the highest germination percentage 48,89 recorded at in medium containing 250 ppm GA3 whereas in control has recorded 42,22 at the end of the 46th day. Other concentrations, 100, 500,1000 and 1500 ppm, achieved a reduction in seed germination compared to control, respectively 28,15, 15,56, 24,44, 34,81. Not only in germination percentage result, but also in other germination associate parameters, the addition of 250 ppm gibberellic acid to Murashige and Skoog medium increased the values compared to the control and ensured a rapid increase and peak between the 8th and 12th days in all parameters.

Sahin, Muhammet; Günay, Hamdi Furkan; Oktar, SA; Taskin, Y
Technological developments have left indelible impacts on the economy all along the line. Every novel invention realized changes production processes rapidly, which concomitantly transforms social life. One of the most apparent examples of this is the First Industrial Revolution emerged in the 18th Century. Subsequent to this development which was considered as the beginning of production in the factory environment, the second industrial revolution based on automation (First half of 20th Century) and the third Industrial Revolution based on electronics (last quarter of the 20th century) were realized. Finally, the Fourth Industrial Revolution (Industry 4.0) process was initiated by Germany in 2011. In line with this process in which cyber-physical systems and robotic technologies are expected to prevail, Super-Smart Society (Society 5.0) model was developed by Japan in 2017. Both Industry 4.0 and Society 5.0 implementations are expected to have a significant impact on economic and social life and to change both labor and Welfare State practices fundamentally. It is also possible that these aforementioned developments may have an impact on social security system of the government. Likewise, the emergence of extensive unemployment condition due to robotic technologies and training for adaptation of available labor force to the new technologies may lead to redesign of the social security system. The aim of this study is to demonstrate the possible impacts of the Industry 4.0 and Society 5.0 processes on social security expenditures. The basic result obtained from the study; unemployment increase and training activities for the labor-force increases social security expenditures, but however digitalization process in Welfare State implementations may be expected to decrease social security expenditures in the long-run depending on efficiency and effectiveness increases in the government.

The purpose of this study was to investigate the phytochemical analysis of D. pentaphyllum and its cytotoxic activity on human cervical cancer (HeLa) cells with possible mechanisms. Total phenolic contents (TPC) and phytochemical analysis of the extract were evaluated using spectrophotometric method and RP-HPLC, respectively. The cytotoxic effect of the extract was evaluated using the MTT assay. The mechanism of the cytotoxic effect of the extract was also evaluated in terms of apoptosis, cell cycle, and mitochondrial membrane potential (MMP) using the fluorometric methods. The TPC of the extract was calculated as 68.9 +/- 2.3 mg gallic acid equivalent per g sample and quercetin was determined as the major phenolic in the extract. The extract showed a selective cytotoxic effect (6.5-fold) on HeLa cells compared to normal fibroblast cells. The cytotoxic effect of the extract was found to be due to the arresting of the cell cycle in the S phase and increasing apoptosis through decreased MMP. Further studies are needed for the comprehensive effects of the extract on cell signaling.

Ilyasoglu, Huri; Nadzieja, Marcin; Guo, Zheng
The aim of this study was to develop a novel dual-functional stabilizer for food-grade Pickering emulsions by grafting caffeic acid onto chitosan via a free radical mediated method. The grafting of caffeic acid onto chitosan was confirmed by UV-vis absorption spectra, FTIR spectra and H-1 NMR spectra and DSC thermogram. The antioxidant properties of the caffeic acid grafted chitosan (CA-g-Ch) were measured by three in vitro assays. Caffeic acid-grafted chitosan displayed much better Fe2+ chelating property than both chitosan and caffeic acid, and retained comparable DPPH radical scavenging activity as caffeic acid. Moreover, the formation of the CA-g-Ch based emulsion was monitored by the turbidity, zeta potential, and particle size measurements. The CA-g-Ch polymers were found to be pH-responsive. The oil (linoleic acid) in water emulsions with the CA-g-Ch (as emulsifier/Pickering stabilizer) was prepared to examine its potential to stabilize Pickering emulsions, as well as its additive antioxidant properties. The results (zeta potential, mean droplet size, creaming index and TBARS values etc) demonstrated that the CA-g-Ch could act as a dual-functional stabilizer for Pickering emulsions. The emulsions made with the CA-g-Ch were found to be stable at a broad pH range of 3-6. Our findings proved that CA-g-Ch as novel dual-functional polymeric surfactant, may have great potential to find applications in food and pharmaceutical industries.

Objective: In this study we investigated in vitro antifungal activity of fluconazole, green tea (Camellia sinensis) and quince leaf (Cydonia oblonga) extracts in Candida strains isolated from blood cultures. Methods: Fifty Candida spp were included to study. Camellia sinensis and Cydonia oblonga leaves collected from Rize and Erzurum/Tortum regions were prepared as an extract. Then stock solutions of the extracts and fluconazole powder obtained from the manufacturer were prepared for use in the Broth Microdilution (BMD) method according to Clinical and Laboratory Standards Institute (CLSI) M27 A3 recommendation. Fluconazole minimum inhibitory concentration (MIC) values obtained from BMD method were evaluated according to CLSI M27 A4 break points. MIC values obtained for Camellia sinensis and Cydonia oblonga were interpreted according to fluconazole break points since there is no break points in the literature. Results: Of the 50 Candida spp. included in the study, 37 (74%) were C. albicans while 13 (26%) were non-albicans species. The most common isolated non-albicans species was C. parapsilosis (14%). For all tested Candida strains MIC 50 and MIC 90 values for fluconazole were found to be 0.125 mu g/mL- 0.25 mu g/mL while they were determined as 0.125 mu g/mL-64 mu g/mL and 0.125 mu g/mL-0.125 mu g/mL for green tea and quince leaves, respectively. Conclusion: According to the low MIC values, it is seen that green tea and quince leaf are in vitro effective against Candida species. However, further extensive in vitro and in vivo studies should be done on the possibility that green tea and quince leaf can be used alternatively in the treatment of invasive Candida infections.
