based on two integration steps, an optimization framework is proposed in this work for the synthesis and design of complex distillation sequence. the first step is to employ heat integration in sequence and reduce the heat consumption and total annual cost of the process. the second one is to increase the exergetic efficiency of sequence by generating power in implemented expanders in sequence....

Original data envelopment analysis models treat decision-making units as independent entities. This feature of data envelopment analysis results in significant diversity in input and output weights, which is irrelevant and problematic from the managerial point of view. In this regard, several methodologies have been developed to measure the efficiency scores based on common weights. Specificall...

results slow and fast-growing groups of the mycobacterium strains were clearly differentiated based on the constructed tree of 56 common mycobacterium isolates. each species with a unique title in the tree was identified; in total, 13 nods with a bootstrap value of over 50% were supported. among the slow-growing group was mycobacterium kansasii, with m. tuberculosis in a cluster with a bootstra...

toxoplasmosis is an infection caused by the protozoan parasite toxoplasma gondii (t.gondii) throughout the world. although usually asymptomatic, the infection can cause serious medical problems in immunocompromised individuals and fetuses. toxoplasmosis also causes considerable economic loss because of abortion in livestock. dna vaccination is a promising approach against intracellular parasite...

objective(s): hypoxia is a serious challenge for treatment of solid tumors. this condition has been manifested to exert significant therapeutic effects on glioblastoma multiform or (who) astrocytoma grade iv. hypoxia contributes numerous changes in cellular mechanisms such as angiogenesis, metastasis and apoptosis evasion. furthermore, in molecular level, hypoxia can cause induction of dna brea...

In this paper, we first define spaces of single difference sequences defined by a sequence of Orlicz functions without convexity and investigate their properties. Then we extend this idea to spaces of double sequences and present a new matrix theoretic approach construction of such double sequence spaces.

In this paper, the dynamic stability analysis of a simply supported beam carrying a sequence of moving masses is investigated. Many applications such as motion of vehicles or trains on bridges, cranes transporting loads along their span, fluid transfer pipe systems and the barrel of different weapons can be represented as a flexible beam carrying moving masses. The periodical traverse of masses...

The three-dimensional structure of an apolipoprotein isolated from the African migratory locust Locusta migratoria has been determined by X-ray analysis to a resolution of 2.5 A. The overall molecular architecture of this protein consists of five long alpha-helices connected by short loops. As predicted from amino acid sequence analyses, these helices are distinctly amphiphilic with the hydroph...
