Increasing of head rise (HR) and decreasing of head loss (HL), simultaneously, are important purpose in the design of different types of fans. Therefore, multi-objective optimization process is more applicable for the design of such turbo machines. In the present study, multi-objective optimization of Forward-Curved (FC) blades centrifugal fans is performed at three steps. At the first step, He...
BACKGROUND Hodgkin lymphoma (HL) survivors have an increased risk of secondary malignancies. We analyzed outcomes in patients with lung cancers following HL treatment. PATIENTS AND METHODS Cases of thoracic malignancies were retrospectively identified from a multi-institutional database of 1976 patients treated for HL from 1969 to 2007. Data regarding risk factors, disease characteristics and...
Damage to the vestibular labyrinth leads to profound nystagmus and vertigo. Over time, the vestibular-ocular system recovers in a process called vestibular compensation leading to reduced nystagmus and vertigo provided visual signals are available. Our study was directed at identifying sources of visual information that could play a role in vestibular compensation. Specifically, we investigated...
لیگاند باز شیف سه دندانه ای هیدرازون (hl) از واکنش بنزهیدرازید و 2-استیل پیریدین (نسبت 1:1) در حلال متانول سنتز شد. کمپلکس های مس(ii) با آنیون های مختلف این لیگاند سنتز و شناسایی شد. نتایج آنالیز عنصری و کریستالوگرافی x-ray نشان داد که وقتی آنیون های cl- و -no3 استفاده شود، لیگاند به صورت سه دندانه ای خنثی عمل کرده و کمپلکس هایی با فرمول [cu(hl)x2] (x=cl, no3) به دست می آید. در صورتی که در حضور...
The Arabidopsis (Arabidopsis thaliana) Early Light-Induced Protein (ELIP) is thought to act as a photoprotectant, reducing the damaging effects of high light (HL). Expression of ELIP2 is activated by multiple environmental stresses related to photoinhibition. We have identified putative regulatory elements in an ELIP2 promoter using an octamer-based frequency comparison method, analyzed the rol...
AIMS This study proposes a computational method for determining the prevalence of metabolic syndrome (MS) and to predict its occurrence using the National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) criteria. The Random Forest (RF) method is also applied to identify significant health parameters. MATERIALS AND METHODS We used data from 5,646 adults aged between 18-7...
Interactions of high-frequency radio waves (RF) with biological tissues are currently being investigated as a therapeutic platform for non-invasive cancer hyperthermia therapy. RF delivers thermal energy into tissues, which increases intra-tumoral drug perfusion and blood-flow. Herein, we describe an optical-based method to optimize the short-term treatment schedules of drug and hyperthermia ad...
Machine learning methods that have been used in data-driven predictive modeling of mineral prospectivity (e.g., artificial neural networks) invariably require large number of training prospect/locations and are unable to handle missing values in certain evidential data. The Random Forests (RF) algorithm, which is a machine learning method, has recently been applied to data-driven predictive map...
