During the First World War, a primary domestic political aim for all belligerent countries was to preserve the socio-economic status quo in order to provide appropriate conditions for the survival of the state. Therefore, war governments paid particular attention to the maintenance of internal order. While doing this, the central authority of governments became paramount and this situation had remarkable repercussions on state-society relations. This article examines the wartime public order policies of the Ottoman government specifically concerning the Ottoman Greeks (Rum) and Armenians living in Istanbul. During the Great War, the . . .se non-Muslim elements were officially regarded as suspects', in other words, as potential political criminals' threatening the internal order of the capital. To control the Ottoman Greeks and Armenians, the war government implemented a number of policing strategies that consisted of deportation of individuals and groups, strict control on travel, and close surveillance of suspects' Daha fazlası Daha az

Emirati women's experience of job satisfaction: Comparative effects of intrinsic and extrinsic

Seydahmet, Ercan

Article | 2018 | SOUTH AFRICAN JOURNAL OF BUSINESS MANAGEMENT49 ( 1 ) , pp.533 - 550

Living and working in a patriarchal culture that encourages modesty, female Emirati employees might face unique challenges such as a male-dominated work environment, higher emotional labour and lack of role models to follow. These challenges potentially shape Emirati women's job-related attitudes and values in a way distinct from that of Western women. Thus, rather than relying on the results of studies conducted in Western countries, researchers should collect data from Emirati women to gain a more accurate understanding of their job attitudes. Consequently, this study examines the effects of some intrinsic and extrinsic factors on . . . Emirati women's job satisfaction. The factors include pay, promotion opportunities, job security, job difficulty, job content quality and interpersonal relations. The results of a hierarchical regression analysis based on data obtained from 364 female Emirati employees indicate that pay and promotion opportunities do not have significant effects, whereas job security, job content quality and interpersonal relations have significant positive effects, and job difficulty has a significant negative effect on Emirati women's job satisfaction. The results further indicate that intrinsic factors explained 10% of variance in job satisfaction above and beyond the extrinsic factors and promotion opportunities. The article discussed the possible meaning of these findings in the context of working in a male-dominated work environment and living in a culture that encourages and values modesty Daha fazlası Daha az

DNA gyrase inhibitors: Novobiocin enhances the survival of Pimpla turionellae (Hym., Ichneumonidae) larvae reared on an artificial diet but other antibiotics do not

Büyükgüzel, Kemal

Article | 2001 | Journal of Applied Entomology125 ( 09.Oct ) , pp.583 - 587

Effects of novobiocin, nalidixic and oxolinic acids, which are potent antibacterial agents, on the survival and development of the hymenopterous endoparasitoid, Pimpla turionellae L. (Ichneumonidae) were investigated alone by rearing the larvae aseptically on chemically defined synthetic diets. Survival of the fifth instar larvae was not significantly affected by diets with different levels of antibiotics tested. A diet containing the lowest level of novobiocin significantly increased yields of pupae and adults. This level also significantly shortened the developmental time for fifth instar but had no significant effect on complete . . .development of the larvae up to adult emergence. Oxolinic acid at the lowest level did not affect the survival but prolonged development of the insect. In general, the rate of development was significantly increased and the survival was decreased with high levels of the antibiotics. However, nalidixic acid caused a striking decrease in the survival at all tested levels. These results suggest that novobiocin and to a lesser extent oxolinic acid are compatible for addition to artificial diet for rearing P. turionellae, which is an important parasitoid used in biological control Daha fazlası Daha az

Yıldız, Ufuk | Hazer, Baki

Article | 1999 | Angewandte Makromolekulare Chemie265 , pp.16 - 19

The free radical dispersion polymerization of styrene (St) and methyl methacrylate (MMA) initiated by poly(oxyethylene) (PEO) macroazoinimer (MIM-400) in water/ethanol, was investigated at three different temperatures (50, 60 and 80°C) for seven polymerization times (3, 6, 9, 12, 24, 36 and 48 h). PSt-PEO and PMMA-PEO networks were obtained. In each case, polymer gel fractions depend on the polymerization temperature and polymerization time. With the same initial concentration of MIM-400, maximum gel fraction was found at 80 wt.-% with St copolymerization while 100 wt.-% in case of copolymerization with MMA at 80°C for 48 h. © Wiley . . .-VCH Verlag GmbH, 1999 Daha fazlası Daha az

Synthesis of polytetrahydrofuran macromonomeric peroxy initiators via cationic polymerization

Savaşkan, Sevil | Volga, Cüneyt | Hazer, Baki

Article | 1998 | Designed Monomers and Polymers1 ( 1 ) , pp.111 - 119

Polytetrahydrofuran macromonomeric initiators (poly-THF-inimer) were synthesized via cationic polymerization of THF, initiated by the combination of AgSbFe 6 and mono-, di-, or tetra-bromomethyl benzoyl peroxides, followed by termination with methacrylate anion. The macroinimers were characterized by 1 H-NMR and GPC techniques. Copolymerization of poly-THF-inimers with methyl methacrylate (MMA) gave crosslinked block copolymers. Sol-gel analysis and swelling measurements of the crosslinked product are also reported.

Synthesis of the new cation exchange resins having poly(styrene-caprolactone) units

Yılmaz-Savaşkan, Sevil | Özbayrak, Hulisi | Hazer, Baki

Article | 1997 | TURKISH JOURNAL OF CHEMISTRY21 ( 4 ) , pp.270 - 276

The crosslinked polystyrene-polycaprolactone, PS-PCL-, block copolymers were prepared by the copolymerization of styrene and poly(caprolacton dimethylmethacrylate) (PCL-DM). The molecular weights of polycaprolactone, PCL, PCL-DM were 1250 and 2000. The swelling in H2O or CHCl3 of the sulfonate and unsulfonated block copolymers were determined under comparable conditions and investigated. The capacities of the obtained ion exchange resins were 1.31 and 1.10 meq/g.

Reactions of anionic living polymers with bromomethyl-functionalized benzoyl peroxides

Hazer, Baki | Hirao, Akira | Volga, Cüneyt

Article | 1999 | Macromolecular Chemistry and Physics200 ( 1 ) , pp.71 - 76

In order to synthesize benzoyl peroxide functionalized polystyrene (PSt), polyisoprene (PI) and poly(methyl methacrylate) (PMMA), anionic living PSt, PI, and PMMA were allowed to react with an excess amount of 4-(bromomethyl)benzoyl tert-butyl peroxide (BMtB) or bis[3,5-bis(bromomethyl)benzoyl] peroxide (BDBP) in tetrahydrofuran (THF) at -78°C. The results indicate that coupling reactions leading to dimers are significant during the reaction. Dimer formation was avoided when the living polystyrene was modified to the alcoholate anion by reaction with ethylene oxide (EO). © Wiley-VCH Verlag GmbH, 1999.

Telechelic polyhydroxyalkanoates/polyhydroxybutyrates (PHAs/PHBs)

Allı, Abdulkadir | Hazer, Baki | Adamus, Grażyna | Kowalczuk, Marek

Book Part | 2017 | Handbook of Telechelic Polyesters, Polycarbonates, and Polyethers , pp.65 - 114

Poly(3-hydroxyalkanoate)s, PHAs, are natural polyesters collected as intracellular granules as a result of a metabolic stress upon unbalanced growth, owing to a limited supply of a necessary nutrient and to the presence of an excess of a carbon source [1,2,3,4,5,6,7-8]. PHAs have material properties ranging from rigid and highly crystalline to elastic, rather amorphous, and flexible. Many studies have been reported on the modification reactions of PHAs to enhance their mechanical and thermal properties [9,10,11,12,13,14,15,16-17]. © 2017 by Pan Stanford Publishing Pte. Ltd.

Synthesis and characterization of poly(Ɛ-caprolactone-co-ethylene glycol) star-type amphiphilic copolymers by “click” chemistry and ring-opening polymerization.

Öztürk, Temel | Kılıçlıoğlu, Ali | Savaş, Bedrettin | Hazer, Baki

Article | 2018 | Journal of Macromolecular Science, Part A: Pure and Applied Chemistry55 ( 8 ) , pp.588 - 594

The synthesis of poly(?-caprolactone-co-ethylene glycol) AAB star-type amphiphilic copolymers were carried out by use of a “click” chemistry reaction to block propargyl polyethylene glycol (propargyl-PEG) to terminally azide poly(?-caprolactone) (PCL-N3). For this purpose, propargyl-PEG was synthesized by the reaction of PEGs (3000 Da, 2000 Da, 1500 Da, and 1000 Da) and propargyl chloride. Terminally chloride poly(?-caprolactone) (PCL-Cl) was carried out by means of ring-opening polymerization (ROP) of ?-caprolactone (CL) and 3-chloro-1,2-propanediol. Synthesis of PCL-N3 was obtained by the chemical interaction of PCL-Cl and sodium . . .azide. By reacting propargyl-PEG and PCL-N3, the star-type amphiphilic copolymers were obtained. The characterization of products was accomplished by using multiple instruments including 1H-NMR, FT-IR, GPC, TGA, contact angles, and elemental analysis techniques. © 2018, © 2018 Taylor & Francis Group, LLC Daha fazlası Daha az

Hazer, Baki | Hazer, Derya Burcu | Çoban, Burak

Article | 2010 | Journal of Polymer Research17 ( 4 ) , pp.567 - 577

Microbial bioelastomers prepared by the autoxidation of the unsaturated medium-long chain length copoly- 3-hydroxyalkanoate's (mlcl-PHAs) based on soybean oily acids (Sy) have been reported. Pseudomonas oleovorans were grown on a series of the mixture of octanoic acid (OA) and Sy with the weight ratio of 20:80, 28:72 and 50:50 in order to obtain unsaturated mlcl-copolyesters coded PHO-Sy-2080, PHO-Sy-2872, and PHO-Sy-5050, respectively. The microorganism was also grown on the mixture of Sy and 10-undecenoic acid (UA) with the weight ratio of 50:50 to obtain unsaturated copolyester coded PHU-Sy-5050. The PHAs obtained were characteri . . .zed by 1H NMR and GC-MS techniques. Double bond contents of the unsaturated PHAs obtained were varying between 0.8 to 20 mol %. Autoxidation of the unsaturated copolyesters were carried out on exposure to air at room temperature in order to obtain new biomaterials whose mechanical strength was improved. Autoxidation kinetics, shelf life, mechanical and thermal properties of these biomaterials were evaluated Daha fazlası Daha az
