Chromosomal DNA must be in single-strand form for important transactions such as replication, transcription, and recombination to occur. The single-strand DNA (ssDNA) is more prone to damage than double-strand DNA (dsDNA), due to greater exposure of chemically reactive moieties in the nitrogenous bases. Thus, there can be agents that damage regions of ssDNA in vivo while being inert toward dsDN...

In this paper, I show how procyclical capital flows originate boom-bust and sunspot episodes in a neoclassical growth model of a small, open economy. All markets are perfect, with the exception of the fact that some upper, endogenous limit is imposed on how much the economy can borrow from foreign creditors, due to potential debtor default. It is shown that the steady state is locally indetermi...

It has been argued that antidumping (AD) facilitates trade liberalization by serving as a release valve for protectionist pressure. We focus on a group of prominent ADusing developing countries and examine the validity of the pressure release hypothesis. The fact that these new AD users generally began using AD after significant trade liberalization supports the hypothesis. Yet, if pressure exi...

Comprising more than 350 dinosaur footprints and at least 38 trackways, the TY tracksite described herein is located close to border of NW Lesotho, near Teyateyaneng (TY), probably identical site originally mentioned by Dornan in 1908. The tridactyl are exposed as natural casts on a cliff overhang fallen block base uppermost Elliot Formation (Sinemurian, Lower Jurassic). High-resolution photogr...

In the scope of dam rehabilitation to manage floods increase or storage, Piano Key Weir is a good solution for concrete dams. The efficiency Weirs now well demonstrated through various experimental studies. Until most prototypes close Type A using symmetrical up- and downstream overhangs structural reasons. position influences inlet outlet key slopes cross section as side crest length influence...

a highly efficient cloning vector was constructed for cloning pcr products by inserting an 80 bp dna fragment into pgem-5zf (+) vector. the xcm i digestion of this vector gave rise to a 3’ overhanging deoxythymidine offering the possibility of cloning pcr products with 3' adenosine overhang created by taq dna polymerase. furthermore, two ecor i sites were added to the construct for identificati...
