Ahşap Yapıştırma ve Yapıştırıcılar
(IUC University Press, 2024) Kurt, Ramazan; Akbulut, Turgay
Ahşabın, ahşap esaslı kompozitlerden mobilyaya, endüstriyel yapılardan köprülere, gökdelenlerden uydulara kadar çok farklı alanlarda yapısal ve yapısal olmayan uygulamalarda kullanılması ahşap yapıştırma teknolojisine bağlıdır. Ahşap malzemenin yapıştırılabilmesi, yoğunlaştırılabilmesi ve işlenebilmesi mühendislik ürünü malzeme olmasına önemli katkı sunar. Ahşap malzemenin alternatiflerine göre heterojen, higroskopik ve anizotropik olması yapıştırıcının doğru bir şekilde seçimi ve uygulamasını önemli hale getirmektedir. Her bir uygulamanın kendine özgü şartlarından dolayı yapıştırma performansını etkileyen (ahşap, yapıştırıcı, süreç/işlem ve kullanım) faktörlerin göz önünde bulundurulması başarılı bir proje için şarttır. Bu bölümde; ahşap malzemenin sağlıklı, güvenli ve çevre dostu, farklı koşullara dayanıklı bir şekilde kullanılması ve fonksiyonel ürünlerin üretilmesi için mühendis, mimar ve ahşap malzeme kullanan tüm meslek mensuplarına ahşap yapıştırma ve yapıştırıcılar hakkında temel bilgi verilmesi amaçlanmıştır.
Palestinian Conflict and Turkey: A Policy of Balance
(2019) Sarıaslan, Fatma
Turkey, as a country built on the heritage of the Ottoman Empire dominated most of the Middle East region for a quite a big part time, has always been interested in Palestinian conflict which has been a chronic problem in the region until today and this issue has always been a priority in its foreign policy. Although Turkey finds the claims of Arab countries more acceptable in the Palestinian conflict, Turkey has avoided damaging relations with both the West and Israel in the events regarding the issue. Despite siding with Palestine in times of crises between two countries, Turkey has maintained its relations of nearly all dimensions including economic and social interactions with Israel, which is the only non-Muslim state in the region. In this article, it is claimed that the policy of Turkey towards Palestinian conflict has primarily been designated upon a balance between the parts of the question. The study also provides a general projection of the development of relations with Israel, in parallel with the ongoing process of Turkey's position on Palestinian conflict and the fluctuant policy pursued on this issue.
Forest Fire Risk Mapping by using GIS Techniques and AHP Method: A Case Study in Bodrum (Turkey)
(2019) Akay, Abdullah Emin; Şahin, Halil
In Turkey, forest areas located along the coastline of the Marmara, the Aegean and the Mediterranean regions are very sensitive to fire. As a result of forest fires, about 10000 hectares of forest area is damaged annually. One of the key elements in firefighting is early detection and quick intervention. In order to achieve this goal, first of all, the forest areas with fire risk should be determined especially for fire sensitive forest areas. The forest fire risk can be evaluated considering various risk factors such as stand structures, topographic factors, proximity to some features (roads, settlements, and water resources), and climatic factors. In this study, GIS techniques and Analytic Hierarchy Process (AHP) method was used to produce forest fire risk map for the first degree fire sensitive forest land located in Bodrum province of Muğla in Turkey. The results indicated that 11.83% and 21.98% of the forest area was categorized as very high and high fire risk, respectively, while 22.28% and 25.93% was moderate and low fire risk, respectively. The fire risk was found to be very low at the rest of the study area (17.98%). To compare the fire risk map with actual forest fire occurrences in the study area, it was overlapped with the fire map indicating forest components where previous forest fires (>1.0 ha) occurred in the study area in last five years. It was found that 38.32% of the areas damaged by the previous fires were categorized as high and very high fire risks zones in fire risk map, while 28.44% was moderate fire risk zones. The result showed that tree species was the most effective risk factor, followed by tree stages and proximity to water resources. This study revealed that the combination of GIS techniques and AHP method is very advantageous approach to map forest areas with fire risk in short time.
Nanomaterials with potential EMI shielding properties
(2019) Altın, Yasin; Bedeloğlu, Ayşe
Nanomaterials exhibit unexpected superior properties such as electrical, magnetic, optical, etc., compared with bulk materials. In this chapter, electromagnetic interference (EMI) shielding properties of different nanomaterials based on metal, metal oxide, ceramic, conductive polymer-modified, and their hybrids are reviewed. The effects of size, shape, structure, and morphology of nanomaterials on EMI shielding properties were also discussed. EMI shielding is mainly realized by three mechanisms, which are absorption, reflection, and multiple reflections. In recent years, academic studies have mostly focused on hybrid nanostructures, which often combine absorption and reflection properties. Meanwhile, an evaluation covering most of the important advancements related to nanomaterials with potential EMI shielding properties is also provided.
Using GIS Techniques for Modeling Noise Propagation from Mechanized Harvesting Equipment
(2019) Akay, Abdullah Emin; Acar, H. Hulusi
The noise is a kind of environmental pollutions that affects human health and decreases performance of people, education, and home life. Harvesting activities in forestry are one of working environments where noise effect is very intense. Noise is an element of environmental pollution that is effective on human health and needs to be controlled. To evaluate the noise effect, maps of noise propagation are used. The noise map is defined as numerical model of noise sources. The changes in sound level determined by measurements in certain points are shown in noise map. Noise maps are used in calculation of average sound level if it is within acceptable limits and in determination of risky areas where employees are adversely effected. Computer-aided systems have been used in modeling noise propagation in recent years. SPreAD-GIS is free program developed to estimate acoustic effects of anthropogenic noise propagation and adapted to ArcGIS software. In this study, it was aimed to introduce SPreAD-GIS program that can be used to model noise propagation caused by mechanized harvesting equipment. In addition, main factors affecting noise propagation in forest (elevation, land use type, temperature, humidity, wind direction and intensity, climate and weather conditions) were evaluated.
