Polimer betonların inşaat mühendisliği uygulamalarında kullanımı yüksek mukavemetlerinin yanı sıra çevresel etkilere ve sıvı temasına karşı geçirimsizlik özelliklerinden dolayı her geçen gün artmaktadır. Bu kapsamda üretilen polimer farklı amaçlar için de kullanılabilirlikleri büyük öneme sahiptir. çalışmada, polyester reçine ile hacimce %0, %15, %30 %45 oranlarında perlit pomza agregalarının k...

Introduction:  The  advent  of  dual-modality  PET/CT  scanners  has  revolutionized  clinical  oncology  by  improving lesion localization and facilitating treatment planning for radiotherapy. In addition, the use of  CT images for CT-based attenuation correction (CTAC) decreases the overall scanning time and creates  a noise-free  attenuation  map  (6map).  CTAC  methods  include  scaling,  s...

In this study, the protection parameters of gamma-ray Borate glass system containing 10Li2O. 10K2O. 20Na2O. xPbO. (60-x) B2O3 where x to be varied as 0, 10, 20, 30, 40, 50 and 60, were investigated using Monte Carlo simulation code Geant4. The coefficients attenuation calculated Geant4 a function incident photon 0.0015 MeV 15 MeV. accuracy simulated results was tested by XCOM program. showed re...

Abstract In this study, the X-ray shielding competence of 15Bi 2 O 3 + 75H BO 10Sm , 10Nd and 10CeO glasses was investigated using Phy-X/PSD simulation software validated XCOM software. The Sm 3+ -doped bismuth-borate glass gave highest linear attenuation coefficients effective atomic number, lowest half-value layer, tenth-value mean free path. Thus, it is most radiation material compared to Nd...

The Soft and Lung tissue equivalent substitute (STES LTES) were developed from urethane PMC121/30 Dry (A B) of Smooth-On, USA. part A B mixed in the ratio 1:1 further with calcium carbonate (CaCO3) at a 2:1 by mass. Air moisture was extracted mixture for 10minutes. This is STES density after air extraction 1.04gcm-3. LTES mixing polystyrene beads 10:1 0.25gcm-3 extraction. subjected to compress...

Abstract To research the improvements of clinical imaging human tissues, tissue-equivalent materials are one reasonable strategies for evaluating impact radiation dosages on tissues. Hence, considering mass and linear attenuation coefficients is a promising method to foresee appropriate tissue-identical material. In this examination, we utilise built-up estimations elemental compositions (mass ...

Introduction: With the extensive application of radiation sources and radioactive materials in various fields, the study of attenuation and absorption of X-rays and gamma-rays in several materials has become an essential and interesting field of research. Glass materials are possible alternatives of concretes for radiation-shielding materials.   Materials and Methods:...

We analyze X-COM: UFO Defense and its successful remake XCOM: Enemy Unknown to understand how remakes can repropose a concept across decades, updating most mechanics, and yet retain the dynamic and aesthetic values that defined the original experience. We use gameplay design patterns along with the MDA framework to understand the changes, identifying an unchanged core among a multitude of diffe...
