Global warming can substantially affect the export of dissolved organic carbon (DOC) from peat-permafrost to aquatic systems. The direct degradability of such peat-derived DOC, however, is poorly constrained because previous permafrost thaw studies have mainly addressed mineral soil catchments or DOC pools that have already been processed in surface waters. We incubated peat cores from a palsa ...

Detection of genetically modified organisms (GMOs) in food is an important issue for all the subjects involved in food control and customer's right. Due to the increasing number of GMOs imported to Iran during the past few years, it has become necessary to screen the products in order to determine the identity of the consumed daily foodstuffs. In this study, following the extraction of genomic ...

Thirty-six human teeth were examined to histologically determine if the Modified Mclnnes Bleaching Technique had any adverse effects on the pulp. Under the conditions of this study, there were no significant pulpal reactions to the bleaching technique even when a substantial amount of the enamel was removed from the facial surface of the crowns. J. Craig Baumgartner 4 The Modified McInnes Bleac...

background: the technique of vertical dome division or tip defining, involves incising the lateral crura and vestibular skin at or lateral to the dome or tip defining point. the incision di-vides the lower lateral cartilage into a lateral segment and a medial segment, which are advanced anteriorly and sutured together to increase tip projection. the present study aimed at assessing a new vertic...

Little is known about the long-term expansion of mire ecosystems, despite their importance in global carbon and hydrogeochemical cycles. It has been firmly established that mires do not expand linearly over time. Despite this, are often assumed to have expanded at a constant rate after initiation simply for lack better understanding. There yet serious attempt determine drivers regional, or larg...

Recurrent ischemic priapism is a problem in clinical treatment. Most of the cases require more invasive surgery to shunt the blood stasis. We introduce a modified technique in treating recurrent ischemic priapism. The technique described is applied to acute ischaemic priapic episodes in patients with a history of stuttering priapism. It was carried out by a Winter's shunt combined with a contin...
