A low cost shading analyzer and site evaluator design to determine solar power system installation area

Shading analyzer systems are necessary for selecting the most suitable installation site to sustain enough solar power. Afterwards, changes in solar data throughout the year must be evaluated along with the identification of obstructions surrounding the installation site in order to analyze shading effects on productivity of the solar power system. In this study, the shading analysis tools are introduced briefly, and a new and different device is developed and explained to analyze shading effect of the environmental obstruction on the site on which the solar power system will be established. Thus, exposure duration of the PV panels to the sunlight can be measured effectively. The device is explained with an application on the installation area selected as a pilot site, Denizli, in Turkey. © 2015 Selami Kesler et al

Standardization of Forensic Interview with the Child Victim

Child abuse which should be considered as a global public health problem, has become increasingly a topical issue due to rapid changes in social life and family structure, migrations. With the child advocacy centers system, which has been organized in our country since 2012, is aimed to manage the forensic and forensic medical evaluation process meticulously with a multidisciplinary approach. There are local differences in the practices of centers located in different provinces. In this study, it is aimed to improve the practice in the field by underlining the main points to be considered during the forensic interview of the cases brought with the claim that they were exposed to sexual abuse. In our study, a standard checklist which will be based on, facilitates the retention of informations that can be obtained through family interviews; it will also serve to improve both the self-regulation of the forensic interviewer and the awareness of the judicial authorities. Determinations were made by blending the information in the literature with our professional observations in our practice

The analysis on photovoltaic electricity generation status, potential and policies of the leading countries in solar energy

Energy, which is the main agenda of our world, is crucially important for the people. Many countries frequently held meetings and discussions with energy agenda. These countries are working to balance the energy demand and supply. For finding the solution are researched, researches should be attempted to present a more efficient way to use energy as well as renewable energy resources effectively. Photovoltaic energy power systems take place as the most dominant source among renewable energy technologies. The most important reason is that it is unlimited and clean energy of the solar power systems. Many studies show that photovoltaic power systems will have an important share in the electricity of the future. In this study, to generate electricity from solar energy using photovoltaic systems have a leading position in some European countries, United States of America, China and Japan's current status and future policies will be analyzed in various comments were made.Photovoltaic policies Solar energy Incentive status

A review of the factors affecting operation and efficiency of photovoltaic based electricity generation systems

One of the most popular techniques of renewable energy generation is the installation of photovoltaic (PV) systems using sunlight to generate electrical power. There are many factors that affecting the operation and efficiency of the PV based electricity generation systems, such as PV cell technology, ambient conditions and selection of required equipment. There is no much study that presents all factors affecting efficiency and operation of the entire PV system, in the literature. This paper provides a detailed review of these factors and also includes suggestions for the design of more efficient systems. The presented detailed overview will be useful to people working on theory, design and/or application of photovoltaic based electricity generation systems.Photovoltaics Efficiency of PV systems

A Novel Triage System Design

Triage systems are clinical risk management systems used to ensure that patients receive the health services they demand from emergency services correctly and safely. Vital signs obtained from patients in the triage unit are one of the most important factors in diagnosis as well as treatment. Vital signs can be measured accurately and precisely, provided certain procedures are followed.Therefore, these complex procedures introduce a heavy crowd in the triage unit. This problem in triage makes it difficult for patients to reach the treatment service they demand. Also, it has a negative influence on hospital staff duringfulfill their duties and reduces their productivity.To prevent these disruptions, it is necessary to develop the novel methodologies that improve the triage system. In this study, we designed a triage system that measures the vital signs simultaneously, consisting of body temperature, oxygen saturation, and blood pressure of the patient applying for triage and transfer data to the digital environment with a barcode system. It is aimed to directing the patient to the correct triage area faster by the usage of the our device huddling together the triage and patient registration procedures

Asymmetric transmission of linearly polarized electromagnetic waves using chiral metamaterials with constant chirality over a certain frequency band

In this study, a dynamic chiral metamaterial (MTM) structure leading to an asymmetric electromagnetic (EM) wave transmission for linear polarization is presented. The structure is composed of square-shaped resonator with gaps on both sides of a dielectric substrate with a certain degree of rotation. The dynamic structure is adjustable via various parameters to fit any desired frequency ranges. Theoretical and experimental analysis of the proposed structure are conducted and given in detail. The suggested model can provide constant chirality over a certain frequency band and thus, it can be used to design myriad novel devices such as EM transmission and antireflection filters, and polarization rotators for desired frequencyTurkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK); Turkish Academy of SciencesPublisher's Versio

Kardiyovasküler İşlemlerde Görüntüleme

Doğum sırasındaki fizyolojik değişimlerle kapanması öngörülen foramen ovale erişkin populasyonun yaklaşık %75’inde tamamen kapanmış olarak izlenirken, %25’inde ise kapanmaz ve patent foramen ovale (PFO) olarak varlığını sürdürür.1 PFO, serebrovasküler olay dahil birçok patoloji (auralı migren, dalgıçlarda dekompresyon hastalığı vs.) ile ilişkilendirilmiştir. İskemik inmelerin %25’inde standart tanısal değerlendirmeye rağmen bir neden bulunamaz ve bu grup kriptojenik inme olarak adlandırılır. PFO ve kriptojenik inme arasındaki patofizyolojik ilişki paradoksal embolizm, PFO içerisinde meydana gelen trombüs, sol atriyal disfonksiyon ve atriyal aritmiler gibi nedenlere bağlı olabilir. Epidemiyolik veriler ve klinik gözlemsel çalışmalar, PFO kapatılmasıyla inme rekürrenslerinin azaldığını gösteren randomize kontrollü çalışmalar tarafından kuvvetle desteklenmektedir.2 PFO’nun tanısında ve perkütan tedavisinde çoklu görüntüleme yöntemleri önem arz etmektedir
