OBJECTIVE Fibrinogen has a role in inflammatory processes and participates in atherosclerotic plaque formation. Despite intensive investigation, there is no clear evidence for a role of variations in the genes coding for the fibrinogen-alpha, fibrinogen-beta, and fibrinogen-gamma polypeptide chains in myocardial infarction. We examined the association of haplotypes in the 50-kb fibrinogen gene ...
this study intends to evaluate interchange series (2005), which are still fundamental coursebooks in the efl curriculum settings, in terms of learning objectives in bloom’s revised taxonomy (2001) to see which levels of bloom's revised taxonomy were more emphasized in these coursebooks. for this purpose, the contents of interchange textbooks were codified based on a coding scheme designed by th...
شبکههای توزیع آب از مهمترین تأسیسات زیربنایی شهرها میباشند. بهینهسازی شبکههای توزیع آب در ابعاد مختلف همواره مورد نظر محققین بوده است. هدف اصلی پژوهش حاضر طرح یک شبکه توزیع آب شهری بر پایه بهینهسازی دو هدفه بود. اهداف بهینهسازی، کمینه نمودن هزینه و بیشینه نمودن امتیاز کلی شبکه از منظر پارامترهای بهرهبرداری و عملکردی منظور شدند. در این راستا پارامترهای بهرهبرداری و عملکردی شبکه بر پایه ...
or pharmaceutical use of traditional Chinese medicine (TCM) has made it absolutely essential to carry out stringent quality control measures. So far, it is widely accepted that multiple constituents are responsible for the therapeutic effects of TCM, and to ensure its quality, therefore, it is necessary to quantitatively determine the multi-bioactive components of TCM. Over the past decades, va...
In this paper, we describe a method to enhance the FTRAN and BTRAN operations in the revised simplex algorithm by using a reduced basis matrix defined by basic columns and nonbasic rows. This submatrix of the standard basis matrix is potentially much smaller, but may change its dimension dynamically from iteration to iteration. For the classical product form update (“eta update”), the idea has ...
Combined heat and power (CHP) production is an increasingly important energy production technology. CHP production is usually applied in back pressure plants, where the heat and power generation follows a joint characteristic. A CHP system may also comprise separate heat and power production facilities. Cost-efficient operation of a CHP system can be planned using an optimisation model based on...
