the acrylated epoxidized soy oil (aeso) was synthesized from epoxidized soy oil and its properties were investigated.  wheat straw particle boards were produced by the synthesized resin with 8% and 13% contents based on straws weight at three pressing times: 8,10 and 12 min. boards’ modulus of rapture, modulus of elasticity, internal bonding, minimum degree of thickness change and water absorpt...

Medium-density fiberboards of acceptable quality were made from a mixture of barky chips from 14 southern hardwoods. Boards made from fiber refined at three different plate clearances did not vary significantly in bending, internal bond (IB), or linear expansion. But, lack of replications and the fact that the refiner was not loaded to capacity caused these results to be inconclusive. Increasin...

This paper describes an alternative finite element model that would yield more accurate results in the prediction of the behavior of Profiled Steel Sheet Dry Board (PSSDB) folded plate structures, which can be considered as an improvement of an earlier proposed model. The PSSDB folded plate structures are being proposed as an alternative to traditional forms of roof construction.The PSSDB syste...

Background The critical role that the board plays in governance of universities clarifies the necessity of evaluating its performance. This study was aimed to evaluate the performance of the boards of medical universities and provide solutions to enhance its performance.   Methods The first phase of present study was a qualitative research in which data were collected through face-to-face semi-...

Patient status boards play an important role in coordinating and communicating about patient care in hospital emergency departments (EDs). Status boards are transitioning from dry-erase whiteboards to electronic systems. Although electronic systems may preserve some surface features of the manual artifacts, important affordances of the manual technology are not always maintained. We compared in...

machinability. Abstract Flakes 3 Inches along the grain. 3/8-inch wide, and 0.02 inch thick were machined from the taproots (with 6inch-high stump) and second logs at eight 31-year-old slash pines. Specific gravity (O.D. weight, green volume) of Items averaged 0.52; rootwood averaged 0.43 and decreased sharply with depth below ground. Forty-four-lb./cu. ft. structural-type particleboards were p...

BACKGROUND Wet needling uses hollow-bore needles to deliver corticosteroids, anesthetics, sclerosants, botulinum toxins, or other agents. In contrast, dry needling requires the insertion of thin monofilament needles, as used in the practice of acupuncture, without the use of injectate into muscles, ligaments, tendons, subcutaneous fascia, and scar tissue. Dry needles may also be inserted in the...

the purpose of this reseach was to examine the influence of resin consumption gradient and press time on the physical and mechanical properties of particleboard produced from citrus tree residues. four resin consumption gradients; 0, 2, 4 and 6% difference between surface and core layers (10-10%, 11-9%, 12-8% and 13-7%) and two press times of 4 and 5 minutes were applied and totally 24 laborato...

The study objects for investigating the possibility of activating both audit committee and board of directors for restricting the practices of earnings management phenomenon. To achieve this objective, a questionnaire had been developed and self-administered for a selected sample consists of 123 auditors working in Jordan based on the simple random sampling method. The study first hypothesis is...
