Bu çalışmada, en önemli çevresel sorunlardan birini çözmek ve düşük maliyetli malzemelerle bitüm performans özelliklerini geliştirmek için atık plastiklerden olan yoğunluklu polietilen (LDPE) kullanılmıştır. Çalışmada kullanılan 2 farklı LDPE 4 oranda (%1, %2, %3 %4) ilave edilerek modifiye bitümler hazırlanmıştır. Saf bitümlere penetrasyon, yumuşama noktası, iki sıcaklıkta (135°C 165°C) dönel ...

Many road construction and maintenance projects are increasingly using recycled material as pavement material. Most of the times, generic sustainability evaluations ascribed to products without fully considering their performance. The potential environmental benefits various alternatives can be analytically evaluated with Life Cycle Assessment while many performance indicators found through lab...

In this work, rheological properties of poly(lactic acid) (PLA), low density polyethylene (LDPE) polymer blends were investigated in the molten state. The experiments were carried on a capillary rheometer. The effect of shear stress, temperature and blending ratio on the flow activation energy at a constant shear stress and melt viscosity of the blends are described. The results showed that the...

as milk is a liquid compound, it needs containers at every stages of movement. the first significant development in milk packaging created at the end of nineteenth century. the flavor changes and shelf life of pasteurized milk and ultra pasteurized milk are affected by processing conditions, packaging materials and microbial growth. off-flavor is an effective factor on reduction of milk quality...

Plastics usage is rising daily because of increased population, modernization, and industrialization, which produces a lot plastic garbage. Due to their various chemical structures, long chain polymeric compositions, thermal/decomposition behavior, it challenging recycle these wastes into hydrocarbon fuels. In the current work, domestic waste was pyrolyzed at 473 973 K in fixed bed reactor comp...

Traditional and modern supply chains for tomato in Cambodia were assessed and possible handling improvements were introduced. Traditional chain involved farmers and collectors in Kandal Province, and wholesalers and retailers in wet markets in the capital of Phnom Penh, about 35 km apart. In the modern chain, only one intermediary between farmers and supermarkets in Phnom Penh was involved; col...

BACKGROUND Living kidney transplantation (LKT) offers the best medical outcomes for organ recipients. Historically, our centre had a low rate of LKT. In 2009, in an effort to increase living organ donation (LOD), a dedicated team was created. Its mandate was to promote LOD at our centre and at referring centres, to coordinate assessments of living organ donors, to facilitate the process, and to...
