In this study, it is aimed to determined and compared high school students’ ideas about momentum and impulse before and after instruction. For this purpose, 26 students were asked open-ended questions. Question 1and 2 are about momentum, question 2 and 3 are about impulse. Consisting of six categories of evaluation categories were created for the analysis of the questions and answer given by the students before and after instruction is placed in this category. After instruction most of the responses to these four Hollister Clothing Canada Online Shopping
questions take part in scientific or scientific fragment categories. Instruction organized according to new program effective to exchange students’ ideas.
Environmental factors, Hollister Coming To Montreal especially the climate, have significant influence on concrete structure. This paper aims to investigate the harmful effects of maritime climate on the durability of concrete structures built in coastal areas. Singly reinforced beam specimens of traditional design and those of densified mixture design algorithm (DMDA) were employed to study the potential problems of concrete structure. Results indicate that cracks on the concrete structure, if go unnoticed, may cause failures. Thus, it is important to know the methodology of achieving high strength and durable concrete in order to avoid formation of cracks in the structural member.
