An Experimental Research on Closed Loop Supply Chain Management with Internet of Things

Abstract. Closed loop supply chain (CLSC) optimization is integration of forward and reverse logistics activities. The importance of CLSC management is increasing by legal regulations, limited energy resources and environmental- financial problems that growing in recent years. However, reverse logistics part of the CLSC is a flow type which is more difficult to made predictions, planning and controls by reason contained uncertainties. This stage, Internet of Things system reduces related uncertainties by providing all the life information of the returned product and substantially attenuates planning of reverse flow activities. In this study, a CLSC is considered that meets demands of the sales&collection center both new and remanufactured product. Manufacturer has three options (refurbishing, disassembly and disposal) to assessing returned products. A mixed integer linear programming model is proposed for a single type of product is completely modular (automobile, computer, telephone, etc.). The model meets customer's products and components demands based period, maximizes profit consist of different sales revenues and total cost (total production, purchase, transportation and disposal costs) and determines how to evaluate all returned products. The proposed model has been verified with the aid of a numerical example by solving in GAMS software and its performance reviewed with experimental studies.Keywords.

Determination of nuclear DNA content and ploidy levels of oat (Avena spp.) accessions belongs to different species

Genom büyüklüğü biyoloji, genetik, taksonomi ve evrim çalışmaları için son derece yararlı birölçüttür. Bu ölçüt türlere özel olduğundan, tür teşhisine ve gen bankalarında korunan genetikmateryalin etiket bilgilerinin hızlı bir şekilde teyit edilebilmesine imkân sağlamaktadır. Buçalışmada flow sitometri ile 13 farklı Avena türüne ait 64 aksesyonun ortalama genombüyüklüklerinin ve ploidi seviyelerinin belirlenmesi hedeflenmiştir. Analiz edilen A. brevis, A.hirtula, A. longiglumis, A. nuda, A. strigosa, A. ventricosa, A. abyssinica, A. barbata, A.murphyi, A. vaviloviana, A. fatua, A. sativa ve A. sterilis türlerine ait aksesyonların ortalamaçekirdek DNA içeriklerinin 8.58 ile 26.54 pg/2C arasında değiştiği belirlenmiştir. Avenaaksesyonlarının çekirdek DNA içerikleri arasındaki farklılık istatistiki olarak önemli bulunmuşve aksesyonların ploidi düzeylerinin diploid ile hekzaploid arasında değiştiği saptanmıştır.Analizlerden elde edilen sonuçlar USDA-NSGC gen bankasında saklanan bu aksesyonlardanbazılarının etiket bilgilerinin doğru olmadığını ortaya çıkarmıştır. Literatürde mevcutçalışmaların sonuçlarından farklı olarak, incelenen dokuz A. brevis aksesyonunun DNAiçeriklerinin 12.21–12.61 pg/2C aralığında olduğu tespit edilmiştir. Benzer şekilde, USDAGRIN sisteminde mevcut tek A. hirtula aksesyonunda daha önce yapılmış çalışmaların aksineçekirdek DNA miktarı 16.16 pg/2C olarak bulunmuştur.Genome size is a good metric used in taxonomy and breeding studies for characterization of the genome and determination of evolutionary distances. It is mostly invariable within species; therefore, genome size estimations could be used for species identification and determination of genetic material integrity in germplasm collections. The present study targets verification of genome sizes and ploidy levels of 64 accessions classified in 13 Avena species using flow cytometry. Estimated nuclear DNA content of A. brevis, A. hirtula, A. longiglumus, A. nuda, A. strigosa, A. ventricosa, A. abyssinica, A. barbata, A. murphyi, A. vaviloviana, A. fatua, A. sativa ve A. sterilis accessions in this study ranged between 8.58–26.45 pg/2C. It was found that nuclear DNA contents of the Avena accessions were statistically different, and ploidy levels of accessions are between diploid and hexaploid. Based on the data obtained from the flow cytometry analyses, it was concluded that some accessions were labelled wrongly in the USDA-NSGC collection. Contradicted from the studies in the literature, nuclear DNA content of nine A. brevis accessions were found between 12.21–12.61 pg/2C. Similarly, nuclear DNA content of the sole A. hirtula accession available in the USDA-GRIN system was found as 16.16 pg/2C, which was reported differently in the previous studies

Učinci 4-vinilcikloheksen diepoksida na testise pasa

This study was aimed at investigating the effects of 4-vinylcyclohexene diepoxide (VCD) on testicular tissue in dogs. For this purpose, 30 mongrel male dogs were used and allocated to 5 groups randomly. The first group (n = 6), used as the control, was administered sesame oil by the intraperitoneal route (i/p). The VCD was administered i/p at doses of 80, 160, 240, 320 mg/kg to the second, third, fourth and the fifth groups (n = 6), respectively, once a day for 8 days. The dogs were surgically castrated on the day after the last VCD injection. The testes were removed immediately and fixed in 10% bouine solution. The testes were subjected to routine tissue processing and examined to determine the testicular damage in each testis. When compared to the control group, it was seen that the seminiferous tubule damage increased significantly in the treatment groups. Malondialdehyde levels reached the highest level in the fifth group, while superoxide dismutase, catalase, glutathione peroxidase activity and glutathione levels were higher in the control group (P0.05). Our results showed that VCD may contribute to the sterilization of male dogs.Cilj ovoga istraživanja bio je ispitati učinak 4-vinilcikloheksen diepoksida (VCD) na tkivo testisa u pasa. U tu je svrhu 30 mužjaka, križanaca, slučajnim odabirom podijeljeno u pet skupina. Prvoj, kontrolnoj skupini (n = 6) dan je VCD sa sezamovim uljem intraperitonealno. Druga skupina primila je VCD intraperitonealno u dozi od 80 mg/kg, treća 160 mg/kg, četvrta 240 mg/kg i peta skupina 320 mg/kg (n = 6), jedanput dnevno tijekom 8 dana. Psi su kastrirani dan nakon posljednje injekcije VCD-a. Testisi su odmah uklonjeni i stavljeni u 10 %-tni Bouineov fiksativ. Podvrgnuti su rutinskoj obradi tkiva te ispitani da se utvrde oštećenja na svakom testisu. U usporedbi s kontrolnom skupinom uočeno je da je u pokusnoj skupini oštećenje sjemenovoda značajno veće. Razine malondialdehida najveće su vrijednosti dosegnule u petoj skupini, dok je aktivnost superoksidne dismutaze, katalaze i glutation-peroksidaze bila veća u kontrolnoj skupini (P0,05). Rezultati pokazuju da VCD može pridonijeti sterilitetu kod muških pasa

TOpic: rare and special cases, the real "Strange cases"

Introduction: The bladder hernia represents approximately 1-3% of all inguinal hernias, where patients aged more than 50 years have a higher incidence (10%). Many factors contribute to the development of a bladder hernia, including the presence of a urinary outlet obstruction causing chronic bladder distention, the loss of bladder tone, pericystitis, the perivesical bladder fat protrusion and the obesity

CO2 mitigation accounting for Thermal Energy Storage (TES) case studies

According to the IPCC, societies can respond to climate changes by adapting to its impacts and by mitigation, that is, by reducing GHG emissions. No single technology can provide all of the mitigation potential in any sector, but many technologies have been acknowledged in being able to contribute to such potential. Among the technologies that can contribute in such potential, Thermal Energy Storage (TES) is not included explicitly, but implicitly as part of technologies such as energy supply, buildings, and industry. To enable a more detailed assessment of the CO2 mitigation potential of TES across many sectors, the group Annex 25 ''Surplus heat management using advanced TES for CO2 mitigation'' of the Energy Conservation through Energy Storage Implementing Agreement (ECES IA) of the International Energy Agency (AEI) present in this article the CO2 mitigation potential of different case studies with integrated TES. This potential is shown using operational and embodied CO2 parameters. Results are difficult to compare since TES is always designed in relation to its application, and each technology impacts the energy system as a whole to different extents. The applications analyzed for operational CO2 are refrigeration, solar power plants, mobile heat storage in industrial waste heat recovery, passive systems in buildings, ATES for a supermarket, greenhouse applications, and dishwasher with zeolite in Germany. The paper shows that the reason for mitigation is different in each application, from energy savings to larger solar share or lowering energy consumption from appliances. The mitigation potential dues to integrated TES is quantified in kg/MW h energy produced or heat delivered. Embodied CO2 in two TES case studies is presented, buildings and solar power plants

The untapped potential of the gaming community: Narrative review.

Background: Video gamers are a population at heightened risk of developing obesity due to the sedentary nature of gaming, increased energy intake, and the disruption caused to their sleep. This increases their risk of developing a number of noncommunicable diseases. To date, research seeking to improve health behaviors has focused on developing novel video games to promote behavior change. Although positive results have emerged from this research, large-scale success has been limited due to the lack of transferability to mainstream games and the focus on children and adolescents. The gaming community has a number of unique aspects, which have received comparatively less attention than the development of new video games. Objective: The purpose of this paper is to highlight under-researched areas that have the potential to encourage positive health behavior among this community. Methods: A narrative review of the lay and academic literature was conducted to provide context and support to our claims that further research could be beneficial in this area. Results: Research has found that advertising can have implicit effects on an individual’s memories, which could influence later decisions. However, the effect of the exponential growth of in-game advertisements and the brand sponsorship of gaming events and professional gamers have not been explored in the gaming community. The possibility of using advertising techniques to encourage positive health behaviors within games or at these events has also not been explored. Research suggests that virtual communities can be effective at disseminating health information, but the efficacy of this needs to be explored using known community influencers within the gaming community. Conclusions: This paper has highlighted a number of potential avenues for the development of interventions within the gaming community. Further research must be conducted alongside game developers to ensure that any in-game developed interventions do not deter gameplay and gamers to ensure that potential approaches are acceptable

The impact of age on post-operative outcomes of colorectal cancer patients undergoing surgical treatment

BACKGROUND: the purpose of study was to evaluate the impact of age on outcomes in colorectal cancer surgery. METHODS: patients on hospital database treated for colorectal cancer during the period 1995 – 2002 were divided into two groups: Group 1 – patients of 75 years or older (n = 154), and Group 2 – those younger than 75 years (n = 532). RESULTS: In Group 1, for colon cancers, proximal tumors were significantly more common (23% vs. 13.5%, p < 0.05), complicated cases were more frequent (46 % vs. 33%, p = 0.002), bowel obstruction more common at presentation (40% vs. 26.5%, p = 0.001), and more frequent emergency surgery required (24% vs. 14%, p = 0.003). Postoperative overall morbidity was higher in the elderly group, but with no differences in surgical complications rate. Overall 5 year survival was 39% vs. 55% (p = 0.0006) and cancer related 5 year survival was 44% vs. 62% (p = 0.0006). Multivariate Cox analysis showed that age was not an independent risk factor for postoperative mortality. CONCLUSION: Preoperative complications and co-morbidities, more advanced disease, and higher postoperative nonsurgical complication rates adversely affect postoperative outcomes after surgery for colorectal cancer in the elderly
