in this paper, a multi-objective method is used to optimize a heat recovery steam generator (hrsg). two objective functions have been used in the optimization, which are irreversibility and hrsg equivalent volume. the former expresses the exergetic efficiency and the latter demonstrates the cost of the hrsg. decision variables are geometric and operational parameters of the hrsg. the results of...

Colorectal carcinoma (CRC) is one of the most common malignancies in the world and the second most frequent cause of cancer-related death in the United States (Jemal et al., 2009). At present, traditional and combined therapeutic approaches (surgery, chemotherapy and radiation) for curing colorectal carcinoma does not show encouraging outcome. The five-year survival in the patients with stage I...

Dear Sir, We believe the article by Clements et al. in the May issue of the JLO to be misleading, in suggesting that the improvement in sensorineural hearing loss in Wegener's granulomatosis treated with combined cytotoxicimmunosuppressive therapy is an unusual finding. In the discussion they state there has been only one similar report (Peiterson and Carlsen, 1965). However, we should like to ...

This review summarizes current data on the pathomechanisms and new genetic findings of combined factor V and VIII deficiency (CF5F8D). Congenital haemorrhagic disorders characterized by deficiency of two clotting factors comprise an interesting group. Among dual coagulation disorders, CF5F8D is the most common type. For the first time combined factor V and VIII deficiency (F5F8D) was reported b...

Recognizing action is an important part of a video surveillance and video retrieval system, in which motion information extracted from video is useful. This paper proposes an action synthesis method, in which Efros et al.’s action recognition method, Chen et al.’s body segmentation method, and Fujiyosi et al.’s method are combined. Chen et al.’s method and Fujiyosi et al.’s method are used as p...

Postoperative radiotherapy (RT) followed by vaginal cuff brachytherapy boost is used to prevent recurrences in the vaginal cuff in endometrial cancer management [1]. 8-year vaginal cuff local control rates for patients with endometrial carcinoma were reported to be 85% with surgery alone,96 % with adjuvant pelvic RT alone and combined pelvic RT + brachytherapy has yielded a local control rate o...

Better survival in combined pulmonary fibrosis and emphysema than in lone pulmonary fibrosis: bias or reality? A response to Centrilobular emphysema combined with pulmonary fibrosis results in improved survival by Todd et al., Fibrogenesis & Tissue Repair 2011, 4:6.Please see related letter http://fibrogenesis.com/content/4/1/17.

introduction moisture limitation is considered as one of the important limiting factors in soybean growth. drought stress affects different aspects of soybean growth through making anatomical, physiological and biochemical changes (tarumingkeng & coto, 2003). under dry tension condition, there will be a disturbance in transmitting nutrients, but some useful soil fungi such as mycorrhiza improve...

Snail1 and Zeb1 are E-cadherin-transcriptional repressors induced during epithelialmesenchymal-transition (EMT). In this article we have analyzed the factors controlling Zeb1 expression during EMT. In NMuMG cells treated with TGF-β, Snail1 RNA and protein are induced one hour after addition of the cytokine preceeding Zeb1 up-regulation that requires six to eight hours. Zeb1 gene expression is c...
