Introduction The Printed Circuit Board Convection Analysis Tools (PCBCAT) are computer programs for predicting the thermal performance of convectively cooled printed circuit boards. The flow field is obtained by solving the depthaveraged (DA) momentum and continuity equations for the fluid layer above the electronic components. The twodimensional DA velocity field data is then incorporated into...

Analysis of Portuguese wheat (Triticum aestivum L.) landrace 'Barbela' revealed the existence of a new x-type high molecular weight-glutenin subunit (HMW-GS) encoded at the Glu-A1 locus, which we named 1Ax1.1. Using one-dimensional and two-dimensional electrophoresis and mass spectrometry, we compared subunit 1Ax1.1 with other subunits encoded at the Glu-A1 locus. Subunit 1Ax1.1 has a theoretic...

Parkinson’s disease (PD) is a neurodegenerative disease which is caused by many factors including progressive degeneration of dopamine (DA)-secreting neurons which reside in the midbrain substantia nigra compacta (SNc). Current available treatments comprise of intake of DA replenishing drugs or implantation of electrical impulse device. However, the short-term effect of the treatments and risks...

Classification studies are widely applied, e.g. in biomedical research to classify objects/patients into predefined groups. The goal is to find a classification function/rule which assigns each object/patient to a unique group with the greatest possible accuracy (classification error). Especially in gene expression experiments often a lot of variables (genes) are measured for only few objects/p...

soil slopes are sometimes curved in plan rather than being straight. this curvature,especially when it is convex, decreases the bearing capacity of the slope. finite element methodhas been used here in this research to investigate the reducing effect of curvature on bearingcapacity of a slope. failure of soil has been assumed to be according to mohr-coulomb criteria;but the flow rule of the soi...

Discriminant analysis (DA) and self-organizing feature maps (SOFM) were used to classify passively evoked auditory event-related potentials (ERP) P(1), N(1), P(2) and N(2). Responses from 16 children with severe behavioral auditory perception deficits, 16 children with marked behavioral auditory perception deficits, and 14 controls were examined. Eighteen ERP amplitude parameters were selected ...

background celiac disease (cd) is a disorder associated with body reaction to gluten. after the gluten intake, an immune reaction against the protein occurs and damages villi of small intestine in celiac patients gradually. objectives the osc, a filtering method for minimization of inter- and intra-spectrometer variations that influence on data acquisition, was applied to biofluid nmr data of c...

This study aimed at investigating the effect of Dynamic Assessment on vocabulary learning of Iranian EFL learners. Although it is widely acknowledged that this type of assessment can prove to be very effective for different aspects of language instruction, not much consideration has been given to DA of vocabulary. This study was an attempt to determine if DA procedures would improve students’ v...

Background Digital image analysis (DA) brings new opportunities to enhance breast cancer pathology testing by providing tools to read tissue-based visual data in a more precise, accurate, and high-throughput manner compared to traditional evaluation performed by a pathologist. The applications may vary from very practical computerassisted diagnosis approaches to obtain more reproducible estimat...
