The Analysis and Impact of Remanufacturing Industry Practices
Ibrahim GURLER
International Journal of Contemporary Economics and Administrative Sciences , 2011,
Abstract: Remanufacturing is a process of bringing used products to "like-new" functional state with warranty to match. Remanufacturing industry is rapidly emerging as an important form of waste prevention and environmentally conscious manufacturing. Products are remanufactured through a series of industrial processes including disassembly, cleaning, inspection, reconditioning, reassembly and testing. The objective of this paper is to review the literature available and examine the terminology surrounding remanufacture, and establish definitions for the various processes such as recycling, refurbishing and reconditioning that are used synonymously. Secondly, via a review of industrial practice, the key business drivers faced by the remanufacturing industry are presented.

Abstract: otulinum toxin injections for blepharospasm prior to ocular surgeries Original Research (2387) Total Article Views Authors: Okumus S, Coskun E, Erbagci , Tatar MG, Comez A, Kaydu E, Yayuspayi R, Gurler B Published Date May 2012 Volume 2012:6 Pages 579 - 583 DOI: http://dx.doi.org/10.2147/OPTH.S30277 Received: 27 January 2012 Accepted: 12 March 2012 Published: 03 May 2012 Seydi Okumus1, Erol Coskun1, brahim Erbagci1, M Gürkan Tatar2, Aysegul Comez1, Erdal Kaydu1, Ramazan Yayuspayi1, Bulent Gurler1 1Department of Ophthalmology, University of Gaziantep, 2Ophthalmology Clinic, Nizip State Hospital, Nizip, Gaziantep, Turkey Purpose: The aim of this study was to show the efficiency of preoperative botulinum toxin A (Botox A) in patients with benign essential blepharospasm who were to undergo ocular surgery with local anesthesia. Materials and methods: Twenty-eight benign essential blepharospasm patients who were administered unilateral Botox A prior to ocular surgery between January 2004 and May 2011 were included in this study. Eleven cases had pterygiums, ten had cataracts, and four had glaucomas, while the remaining three had aphakia. All cases’ severity of spasm (stage 0–4) and eyelid closing forces (stage 1–4) were evaluated according to the Jankovic scale prior to the injection, at 3 days, 14 days, 1 month, and 3 months after Botox A injection. Results: Of the patients enrolled in the study, 16 were female and 12 were male, with an average age of 55.52 ± 1.53 years (52–65). Average onset of the Botox injection's effect was 2.8 ± 0.9 (2–5) days. Its effect lingered for about 11.5 ± 3.6 (8–22) weeks. The severity of spasm and eyelid closing forces of all the patients enrolled were compared prior to the injection at 3 and 14 days and the first and third months after the injection. There were statistically significant differences between prior to the injection and 3 days (P = 0.001), 14 days (P < 0.001) and 1 month after the injection (P <0.001). There was no statistically significant difference between prior to the injection and 3 months after the injection (P = 0.513). Fourteen days following the injection, the surgeries were successfully performed. Conclusion: Botox A administered prior to ocular surgery will control both blepharospasm and lower the risks that can be encountered before and during surgery, thus increasing the comfort of the patient and the surgeon.
The Mrl Function of the K-Out-Of-N System with Nonidentical Components in the System Level
Selma Gurler,Ismihan Bayramoglu
Sel?uk Journal of Applied Mathematics , 2006,
Abstract: A k-out-of-n system is working if at least k of its n components are operating. The system breaks down at the time of the (n-k+1) th component failure. Since all components start working at the same time, this approach leads to a kind of redundancy called active redundancy of n-k components. Important particular cases of k-out-of-n system are parallel and series systems corresponding to k=1 and k=n, respectively. In this paper, we consider the mean residual life (MRL) function of a parallel and k-out-of-n systems consisting of n components having independent and nonidentically distributed lifetimes. We provide new representations of the MRL function for such systems. The MRL functions of systems consisting of components having exponential and power distributed lifetimes are presented. Also we introduce a numerical example to study the effect of increasing the system level and various parameters on the mean residual life of the systems. Further, the relation between the mean residual life for the system and the mean residual life of its components is investigated.
Future of Global Agriculture: An Ecological Evaluation
Arslan Zafer Gurler,Gulistan Erdal,Halil Kizilaslan
Journal of Applied Sciences , 2005,
Abstract: In this study, environmental effects of agriculture has been tried to be revealed with use of climate changes until 2025 as data. With this aim, forecasting results estimated with data of past 22 years back to year 2002 were included in the study. Subjects of projection were described as consumptions of P, N, pesticides and usage of irrigation water, agricultural areas, population and GDP. With the World wide projection made for the year of 2025, it is estimated values of consumptions as P 51. 106 tons, N 105.106 tons, irrigation water 327,80. 106 ha, agricultural areas 5140. 106 ha, population 7934. 106, National product 76146. 106 $. Also, dominant features of countries are determined and analyzed with correlation analysis made between population, GDP and other variables. Generally, while GDP and population variables has no effect on P consumption, it has been seen to be effective especially over N consumption, irrigation water usage and agricultural areas.
The Effects of Agricultural Development on Ecosystem and the Sustainability of Development
A. Zafer Gurler,Gulistan Erdal,Hilmi Erdal
Journal of Agronomy , 2006,
Abstract: One of the several variants of global warming is the effect of agricultural development on ecosystem. Each of these variants creates a global threat in terms of a cause-effect relationship. In this study, a projection was made to discover possible levels of major elements of agricultural development such as chemical manure, irrigation water, use of pesticide in 2020 year. Thus, the effect of agriculture on ecosystem in the future was estimated on the basis of world scale and Turkey. On the other hand, in the analysis made in accordance with conjectural criterions, it is revealed that Turkey which is acknowledged to be developing is under threat in terms of sustainable development.

Journal of Animal and Veterinary Advances , 2012, DOI: 10.3923/javaa.2011.1012.1018
Abstract: In this study, a 100 carp fish that offered for sale in public bazaar in Afyonkarahisar were microbiologically examined in 2009 period (15 June to 15 July). In most of these samples, aerob total count was found between 107 and 108 kob mL-1. Coliform count ranked 2nd after the aerob total count. Most of micrococcus and staphylococcus were found at 104-105 level. Although, the count of enterococcus was generally between 105 and 106, the count of enterobacter count was generally 106-107. Mold was not isolated from samples. Coliform bacteria level was 107-108 kob mL-1. However, E. coli was under the detection level in most of the samples while it was 104-105 in the rest. On the other hand, Salmonella highly important for food infections was determined in 3% of the carp fish samples.
