Supracondylar humerus fractures are common fractures around the elbow. Open fractures, comminuted metaphyseal fractures and also fractures with bone loss may need to be treated with external fixators. The aim of this study is to compare two different external fixators, tubular external fixators and polymethyl methacrylate with K wires external fixators, with regard to stiffness and stability for metaphyseal-diaphyseal osteotomies of distal humerus close to the joint. Six matched pairs (24 specimens) of second-generation sawbone humerus were prepared in a standard fashion to create a metaphysea ...Daha fazlası
This study proposes a new correlation improvement technique for the optimum node removal location to get improved modal assurance criterion (MAC) matrix. The technique is applied to updating of the finite element model (FEM) of a structure. The developed routine is tried on a utility helicopter. It is proven that it is capable of showing better performance than the coordinate MAC (coMAC), commonly used in such analyses. Commercial software is utilized for the finite element analysis of the helicopter fuselage and tail. Experimental modal analyses are also performed for updating the model for t ...Daha fazlası

Objectives: To define the thoughts, emotions, experiences and perceptions of women with multiple sclerosis (MS) and to determine sexual, physical, and emotional effects of MS on patients. Methods: Twenty-one women were included into this qualitatively designed study. Results: Three baseline themes were defined as “uncertainty” arising from complaints due to numbness in extremities and loss of sense, balance or vision, “alterations in sexual life,” and “inability” as a result of deformities in marital status and gender role. Conclusion: Healthcare providers should evaluate MS patients meticulou ...Daha fazlası
Background and Purpose: The term of Complementary and Alternative Medication (CAM) is described by patients as all types of practices to prevent or treat illnesses, which are not currently considered as a part of conventional medicine. Although the advance in treatment for migraine, some patients prefer CAM therapies due to their concerns about conventional therapies. The aim of this study was to evaluate the association between CAM use and chronicity of migraine among Turkish migraineurs. Methods: Consecutive episodic and chronic migraine patients were recruited. A questionnaire of a list of ...Daha fazlası
This chapter presents the subject area of the Internet as an international form of media and examines related issues. It begins by considering the Internet as a source of information in various forms of social network sites that enables any individual to post their experiences, opinions and evaluations of tourism destination. This provides a summary of the existing state of knowledge concerning to social network sites and word of mouth (WMO) recommendation. In addition, it serves to clarify the associated word of mouth and market share development.

In today’s world, the pressure of competition considerably changed because of the increasing pressure of market competition, changes in customer expectations due to global warming and the globalization of the economy. Growing pressures in supply chain activities urge to companies to adopt new approaches by reducing waste and planning environmental friendly processes, such as recycling, reuse, and remanufacturing. There have been several studies proposed that lean activities can help make the case for environmental impact reduction to companies. Thus, most companies have reorganized their suppl ...Daha fazlası
Even though various studies are proposed to evaluate and determine the best suppliers, studies generally consider similar factors such as cost, quality, delivery time etc. in the supplier selection problem. Nowadays, some lean and green issues such as on time (JIT) delivery, waste reduction, avoidance and treatment of hazardous materials, energy efficiency, occupational health and safety, corporate social responsibility, etc. started to be addressed together with the supplier selection process. Lean and Green Supply Chain Management (L-GSCM) is a dynamic field for companies to gain advantages ...Daha fazlası

The dynamics of Supply Chain Management (SCM) have changed over the years; new paradigms are added into the SCM as a response to changes related with increasing environmental concerns and pressures. Therefore, lean and green practices in a company belong to its most important factors to enhance the company’s performance. In this study a new model, inspired by an automotive supply chain, is proposed for lean and green closed-loop supply chain management. In this model, we deal with lean and green drivers to set the objectives of the decision makers (DMs) as follows; (1) Construction: The amount ...Daha fazlası
Planning, which means to determine the way in advance, has occured throughout history. The planning process, which includes elements such as determining current sources and evaluating options, is also important because of decreasing inequities and correcting imbalances. After World War II, planning was set as one of the development method. After experiences of economical plans, in 1961, the State Planning Organization (SPO) was founded and made planning more formal in Turkey. Development plans, which have continued with the Development Ministry that was founded in 2011, are important documents ...Daha fazlası
In this study, hydroxy (HHO) dry cell performances in terms of voltage, current and temperature were modeled with Rule-Based Mamdani-Type Fuzzy (RBMTF) modeling technique. Input parameters plate combination and time, output parameters voltage, current, temperature were described by RBMTF if-the rules. Current, voltage and temperature were measured for the different membership functions. Numerical parameters of input and output variables were fuzzificated as linguistic variables: very very low (L-1), very low (L-2), low (L-3), negative medium (L-4), medium (L-5), positive medium (L-6), high (L- ...Daha fazlası

Transforaminal lumbar interbody fusion was an alternative to posterior lumbar interbody fusion for decompression surgeries. This study investigates the biomechanical responses of the unilateral and bilateral pedicle screw fixations with/without transforaminal lumbar interbody fusion cages under axial compression, flexion, and torsional loads. Ovine vertebrae were used in this study. Cadavers, randomly divided into five, were intact control group, bilateral pedicle screw fixation group, bilateral pedicle screw fixation group with transforaminal lumbar interbody fusion cage, unilateral pedicle s ...Daha fazlası
In this study, modeling of a helicopter fuselage panel with active vibration control is carried out. In order to represent the helicopter body shell, a cabin panel clamped from four edges is designed. Piezoelectric patches are attached on the body according to the literature. The dynamic characteristics of the structure are obtained by finite element based modal analysis and exporting of state space matrices. The numerical model of the cabin panel is characterized with regard to active vibration control loop. Vibration data obtained from the helicopter operational tests is applied as a distort ...Daha fazlası
