Background and Aim: One of the important factors in microleakage of fissure sealants is saliva contamination. Researchers believe that applying bonding agents can reduce the microleakage. The present study compared the microleakage of a fissure sealant contaminated with artificial saliva at different curing times with or without using a bonding agent. Materials and Methods: In this in-vitro ...

biosecurity in the production of broiler chickens is very important but it is hard or even impossible to maintain; hence, promotion of immune responses could control diseases in chickens. at present study, the effect of six levels of oil-extracted propolis (0, 50, 100, 150, 200 and 250 mg/kg ration) on immune system against newcastle virus was studied using a completely randomized design with 3...

Introduction In UC Santa Cruz’s first ever offering of a Game Design Seminar, I had the involving experience of developing four games from scratch, participating in discussions relevant to the times, and developing my skill in computer game design. This paper documents my thinking, efforts, and analysis of mine and other’s games developed for the seminar. In the first section, I will briefly di...

Impossible differential attack is a well-known mean to examine robustness of block ciphers. Using impossible differ- ential cryptanalysis, we analyze security of a family of lightweight block ciphers, named Midori, that are designed considering low energy consumption. Midori state size can be either 64 bits for Midori64 or 128 bits for Midori128; however, both vers...

There is a class of pictures called pictures of impossible objects. Although they are named “impossible,” they are not necessarily impossible. Some of them can be realized as three-dimensional solid objects. In this study, we show that the impression of impossibility comes from the human preference for right angles. This preference can also explain another visual illusion called impossible moti...
