Morphologic and molecular assessments of cucumber (Cucumis sativus L.) landraces
In this study, 90 locally grown cucumber (Cucumis sativus L.) landraces were collected and morphologically characterized using 20 descriptors derived from UPOV (International Union for the Protection of New Varieties of Plants). Genetic diversity and relationships of the genotypes were revealed using 20 sequence-related amplified polymorphism (SRAP) marker combinations. The discrimination power of each polymorphic marker (estimated by the polymorphism information content) ranged from 0.15 to 0.99 with an average of 0.73. Dice's similarity coefficient ranged between 0.00-1.00. The cluster analysis that was conducted using the unweighted pair group method of arithmetic averages (UPGMA) for both molecular and morphologic data showed that all of the genotypes fell into two main groups and many subdivisions. According to morphological data, fruit length, diameter and weight of the genotypes were determined between 6.5 - 32.5 cm, 25 - 52 mm and, 28 - 625 g respectively. It is clear from the results, a moderate level of genetic diversity, which has the potential for broadening the genetic base, was observed among the Turkish cucumber landraces
The Critical Success Factors of Erp Selection and Implementation: A Case Study in Logistics Sector
Today’s competitive business environment requires much greater interaction between customer and business. This means that the organization must be closely linked to both supplier and customer in order to produce goods and provide faster deliveries. In order to achieve this, the organizations need to have efficient planning and control systems in all the processes of the organization. In this case, information technology is one of the sources which organizations can apply. Especially, Enterprise Resource Planning (ERP) is just at the heart of daily operations of a company, which leads to efficient processes. In this study, how Enterprise Resource Planning (ERP), which enables such sources as workforce, machine and materials needed for the production of goods and services in organizations to be used efficiently, was founded and the problems that organizations face with during foundation were explained. In the study, qualitative analysis method was used. At the end of the study, problems during implementation of ERP system was determined and suggestions regarding to the solutions were presented
DETERMINATIONS OF REAL ESTATE TAX VALUES VIA GEOGRAPHİC INFORMATİON NETWORK ANALYSES TECHNIQUES
Gelişmiş ülkelerde emlak vergileri (EV) yerel yönetimler ve merkezi idareler için önemli bir kaynak teşkil etmektedir. Ancak ülkemizde yasal mevzuat, uygulayıcılar ve kurumlar arası koordinasyon eksikliği, vergiye esas taşınmazların belirlenememesi, takip edilememesi ve taşınmaz değer karşılıklarının doğru olarak tespit edilememesine neden olmaktadır. Bunların sonucunda, önemli oranda ekonomik kayıp ortaya çıkmaktadır. Günümüzde bilgi teknolojileri yardımıyla vergi mükellefleri ve ilgili kurumların emlak vergi değerlerine optimal bir şekilde erişimi sağlayacak ve vergi kayıpları minimum seviyeye indirecek sistemlerin kurulması mümkündür. Yapılan bu çalışmada, Coğrafi Bilgi Sistemleri teknikleri kullanılarak, yasal mevzuatta bölge, cadde veya sokak bazında belirlenen asgari emlak vergi değerlerinin taşınmazlara yansıtılması ve asgari beyan sisteminin kontrolü amacıyla bir model tasarlanarak örnek bir uygulama yapılmıştır. Bu amaçla yol ağı ile kadastral veriler ilişkilendirilerek vergiye esas taşınmazlar için bir veri tabanı (VT) tasarımı gerçekleştirilmiştir. Real estate tax is a very big resource for local authorities and central administrations in developed countries. On the other hand, because of lacking of legal legislation, applicators and communication between institutions, real estates having responsibility for tax and real estate values can not be determined. This lead to an important economical loss. Today, constitution of systems which allow taxpayers and related institutions to access real estate tax values optimally and minimize tax loss is possible via information technologies. In this study, minimum real estate values specified in district or street based were taken into consideration for tax. Then, a model was designed and a sample application was performed to control minimum declaration values. For this purpose, after linking road network and cadastral data, a database design was realized for real estates having responsibility for tax
Urodynamic assessment of short-term effects of pelvic radiotherapy on bladder function in patients with gynecologic cancers
Objectives: To determine the short-term effects of adjuvant or primary curative radiotherapy (RT) on the urinary system in women with gynecologic cancer.
Material and methods: This is a prospective, concurrent cohort study including 55 patients with gynecologic cancer who were divided into three groups. Group 1 included 10 patients who were administered adjuvant RT following a radical hysterectomy (RH); Group 2 included 36 patients who were administered adjuvant RT following a type 1 hysterectomy and Group 3 included 9 patients who were administered primary curative RT. Urogynecologic assessments were carried out on patients before and six months after the treatment.
Results: Compared to pretreatment, no significant differences were observed in any of the three groups after treatment in terms of incontinence, first urge to urinate, normal urge to urinate, severe urge to urinate and changes in residual urine volumes. There was a significant decrease in maximal vesical pressure after treatment in Group 1 and Group 3. The maximum detrusor pressure decreased significantly in Group 1. The post-treatment decline in bladder capacity in Group 1 and Group 2 was also significant.
Conclusions: RH and pelvic RT cause lower urinary system dysfunction. Especially patients who receive primary curative RT and patients who are administered RT after RH, where more pelvic denervation occurs, are at higher risk due to high doses of RT
Municipal solid waste landfill site selection using Multi-Criteria Decision Making and GIS: case study of Bursa province
Rapid population growth, economic development and industrialization have created many problems related to municipal solid waste management (MSWM) in developing countries like Turkey. Solid waste disposal has become mandatory because of increasingly common factors such as global warming and contamination of water resources. In recent years, this situation has revealed the need for effective management of solid waste. Suitable site selection requires evaluation and analysis of multiplefactor. Therefore, it is very important that the design of landfill site selection take into account environmental, economical and sociologicalfactors. In order to do this, the Geographical Information System (GIS) used with Multi Criteria Decision Making (MCDM) techniques is a useful tool for creating a model. One such MCDM is the Spatial-integrated Technique for Order Preference by Similarity to Ideal Solution (TOPSIS). In this study, TOPSIS was applied to integrate environmental, economical and sociological sensitivity into determine alternative solid waste landfill sites for Bursa Province, Turkey. Using the data obtained by comparing the geo-statistics, six of the most suitable landfill areas were determined. In the final stage, as a result of this study, the Kayapa district was identified as the most suitable landfill area
The Effect of Gadolinium and Lanthanum on the Mortality of Daphnia magna
Rare earth elements (REEs) have been recently identified as emergent contaminants because of their numerous and increasing applications in technology. The impact of REEs on downstream ecosystems, notably aquatic organisms, is of particular concern, but has to date been largely overlooked. The purpose of this study were to generate toxicological information regarding these poorly studied Gadolinium and Lanthanum elements to determine the current risk associated with these elements. The results of this work indicate a notable D. magna mortality in high concentration of La and Gad. The findings from our study also indicate that Gad is more toxic than La. Due to this mortality effect of La and Gad to D. magna, it will be important for the ensuring continuity of the ecosystem to monitor especially aquatic environments and to treat them with appropriate treatment methods from contaminated environments
Additive Manufacturing of Isotropic NdFeB PPS Bonded Permanent Magnets
Extrusion based additive manufacturing of polymer composite magnets can increase the solid loading volume fraction with greater mechanical force through the printing nozzle as compared to traditional injection molding process. About 63 vol% of isotropic NdFeB magnet powders were compounded with 37 vol% of polyphenylene sulfide and bonded permanent magnets were fabricated while using Big Area Additive Manufacturing without any degradation in magnetic properties. The polyphenylene sulfide bonded magnets have a tensile stress of 20 MPa, almost double than that of nylon bonded permanent magnets. Additively manufactured and surface-protective-resin coated bonded magnets meet the industrial stability criterion of up to 175 °C with a flux-loss of 2.35% over 1000 h. They also exhibit better corrosion resistance behavior when exposed to acidic (pH = 1.35) solution for 24 h and also annealed at 80 °C over 100 h (at 95% relative humidity) over without coated magnets. Thus, polyphenylene sulfide bonded, additively manufactured, protective resin coated bonded permanent magnets provide better thermal, mechanical, and magnetic properties
