Determining the ammonia capture efficiency in combined contact device

the significance of conjunction as a cohesive device in teaching writing

the research questions were as follows: 1. is there any relationship between the students concious awareness of the form and implications of the conjuncations and their improvement in using appropriate conjunctions? 2. does students knowledge of the from and the implications of the conjunctions help them to produce more coherent writings. 3. does a comparison between english conjunctions and th...

The Impact of Verapamil Gel on Efficiency of Tissue Expander Device in Plastic and Reconstructive Surgery

BACKGROUND  One of the weaknesses of recovering the skin defects by tissue expander device is that it needs relatively long time and it has complications. Since verapamil gel reduces the production of these capsules around silicone prosthesis and reduces the formation of collagen in the capsule areas. The aim of this study was to examine the effect of verapamil gel on efficiency of tissue...

Determining a Surrogate Contact Pair in a Hertzian Contact Problem.

Laboratory testing of contact phenomena can be prohibitively expensive if the interacting bodies are geometrically complicated. This work demonstrates means to mitigate such problems by exploiting the established observation that two geometrically dissimilar contact pairs may exhibit the same contact mechanics. Specific formulas are derived that allow a complicated Hertzian contact pair to be r...

Determining language contact effects in ancient contact situations

Proving the existence of ancient language contacts is easy; proving the existence of ancient contact-induced language change is much more difficult, by comparison to analyses of modern contact situations. This paper surveys some ancient contacts and their effects on the languages. The main conclusion is that the historical methods used for analyzing better-documented contact situations can be a...
