The target of this study was to investigate the possibility of MDF productionfrom Eucalyptus camaldulensis wood. MDF fibers were produced applying threelevels of steaming time. Laboratory MDF boards were produced using thegenerated fibers and different pressing temperature and time. Physical andmechanical properties of MDF panels were measured using relevant EU testmethods and were statisticall...

این پژوهش با هدف بررسی ظرفیت تحمل تنش در اتصال گوشه‏ای فارسی ساخته‌شده با دم چلچله در تخته خرده‌چوب و تخته فیبر نیمه‌سنگین (MDF) در زیر بار کششی قطری صورت گرفته است. در این تحقیق، اثر ارتفاع دم چلچله در دو سطح 9 و 14 میلی‌متر، نوع چسب پلی وینیل استات (PVAs) و سیانو آکریلات (CA)، و جنس اعضای اتصال (تخته خرده‌چوب و MDF) زیر بار کششی قطری بررسی شد. اتصال‏های ساخته‌شده با حالت بدون چسب مقایسه شدند....

In this paper, we present a self-organizing framework called the SHOSLIF-M for learning and recognizing spa-tiotemporal events (or patterns) from intensity image sequences. The proposed framework consists of a mul-ticlass, multivariate discriminant analysis to automatically select the most discriminating features (MDF), a space partition tree to achieve a logarithmic retrieval time complexity f...

The relationship between structure and inhibition activity on carbonic anhydrase I of a set of forty substituted 1,3,4-thiadiazoleand 1,3,4-thiadiazoline-disulfonamides has been investigated by using the Molecular Descriptors Family method. The molecular descriptors family has been generated starting with the information obtained from the compounds structure and the descriptors were calculated....

We investigate the nature of the newly discovered Ultra Faint dwarf spheroidal galaxies (UF dSphs) in a general cosmological context simultaneously accounting for various “classical“ dSphs and Milky Way properties including their Metallicity Distribution Function (MDF). To this aim we extend the merger tree approach previously developed to include the presence of star-forming minihaloes, and a ...

The authors have previously shown that epithelioid cells isolated from mice secrete a factor, called macrophage deactivating factor (MDF), that promptly deactivates superoxide release by activated macrophages and neutrophils. In this paper some biological properties of a polyclonal rat antiserum directed to MDF and other substances secreted by these cells are described. The immunoglobulin fract...

In this study, the effects of various boron compounds on the termite resistance of MDF panels were evaluated. Either borax (BX), boric acid (BA), zinc borate (ZB), or sodium perborate tetrahydrate (SPT) were added to urea-formaldehyde (UF) resin at target contents of 1%, 1.5%, 2% and 2.5% based on dry fiber weight. The panels were then manufactured using 12% urea-formaldehyde resin and 1% NH(4)...

The reliability of surface electromyographic (sEMG) variables during swallowing determines the potential usefulness of these measures in swallowing assessment and treatment. This study aimed to establish the reliability of the sEMG measures of the swallowing function of muscles during different swallowing conditions in healthy young and old volunteers. Two groups of volunteers (24 older adults,...

This paper describes and analyses the performance of a novel feature extraction technique for the recognition of segmented/cursive characters that may be used in the context of a segmentation-based handwritten word recognition system. The Modified Direction Feature (MDF) extraction technique builds upon the Direction Feature (DF) technique proposed previously that extracts direction information...

wnloaded role of the estrogen receptor β (ERβ) in the colon has received considerable interest, yet in vivo ls are needed to better define its protective actions. In the present study, wild-type (WT), ERα, Rβ knockout (αERKO and βERKO) mice were injected with azoxymethane, a colon chemical carn. Fourteen weeks after azoxymethane exposure, the incidence of aberrant crypt foci (ACF) was ed by met...
