in this research the possibility of vine pruning fibers in combination with wood fibers was studied in order to fabricate medium density fiberboard. vine pruning fibers content in three levels of 0/100, 30/70 and 60/40 (weight percent) and press time in three levels of 4, 5 and 6 minutes were as variable factors. one layer panels with a density of 0.65 g/cm3 and thickness of 15 mm were made. th...

introduction: to recognize the myelinated nerve fibers of the external and extreme capsules in human brain. materials and methods: 10 adult and normal brains (20 hemispheres) from both sexes were studied using 15 mm serial secions in all three cardinal planes after fixation and processing. these sections were stained by klüver – barrera and heidenhin – woelcke methods. results: some fibers from...

PURPOSE The micronization using milling process to enhance dissolution rate is extremely inefficient due to a high energy input, and disruptions in the crystal lattice which can cause physical or chemical instability. Therefore, the aim of the present study is to use in situ micronization process through pH change method to produce micron-size gliclazide particles for fast dissolution hence bet...

OBJECTIVE To study in swine the hemodynamic changes secondary to the use of stabilizers for off-pump coronary artery bypass graft surgeries by means of both a suction device "Octopus" and a compression device (Speroni). METHODS Ten swine underwent median sternotomy. Monitoring of ECG, continuous cardiac output, mean arterial pressure, mean pulmonary artery pressure, mean right and left atrial...

BACKGROUND THE PRESENT STUDY AIMED: to assess prescribing patterns in the treatment of major depression, bipolar disorder type I, cyclothymia, and dysthymia from 1996 to 2007 in a day hospital setting; to evaluate the prevalence of the above-mentioned mood disorders and gender distribution; and to relate familiality, comorbidity, and marital status to each diagnosis. METHODS Medical records f...

The article considers the features of designing bases and foundations buildings structures in permafrost zone. It is shown that developing global warming requires, case using principle I, to provide for cooling base with help heat stabilizers. recommended use horizontal stabilizers, which contribute formation a slab frozen soil at base, making it possible, some cases, abandon piles. When ventil...

This paper presents a current literature review (from the years 2017–2022) on issues related to application of power system stabilizers (PSSs) for damping electromechanical swings in systems (PSs). After initial selection papers found databases used, over 600 publications were qualified this review, which 216 subjected detailed analysis. In following problems are described: applications classic...

The application of fibers to reinforce cementitious materials is a well-known subject. At first, asbestos fibers are used in industrial process to produce fiber reinforced cement sheets. Thereafter, various types of synthetic fibers are produced and used as asbestos substitutes. The aim of the present work is to evaluate the effect of synthetic fibers on the flexural behavior of cementitious co...
