سازه های صفح های- مکعبی، اشکال پایه به کار رفته در تولید انواع قفسه و کابینت آشپزخانه می باشند. در این بررسی ساخته و در معرض آزمون mdf قفسه های چهارگوش در اندازه واقعی کابینت آشپزخانه با استفاده از پیچ و دو نوع تخته کهنگی زود هنگام (تسریع شده) قرار گرفتند. در کل 50 قفسه ساخته و آزمون شدند. 25 قفسه از تخته بدون روکش و بدون نوار لبه چسبان و 25 قفسه دیگر که به عینه همانند بودند از تخته روکش ملا...

Microdialysis enables in-depth mechanistic study of the cutaneous circulation in humans. However, whether the insertion or presence of the microdialysis fiber (MDF) affects the skin circulation or its responses is unknown. We tested whether the cutaneous vascular response to whole body heating (WBH) was affected by MDF or by pretreatment with ice (part 1) or local anesthesia (LA; part 2). Eleve...
The aim of the paper is to present the results obtained by utilization of an original approach called Molecular Descriptors Family on Structure-Property (MDF-SPR) and Structure-Activity Relationships (MDF-SAR) applied on classes of chemical compounds and its usefulness as precursors of models elaboration of new compounds with better properties and/or activities and low production costs. The MDF...
A recently proposed Minimum Discarded Fill (MDF ) ordering (or pivoting) technique is e ective in nding high quality ILU (`) preconditioners, especially for problems arising from unstructured nite element grids. This algorithm can identify anisotropy in complicated physical structures and orders the unknowns in a \preferred" direction. However, the MDF ordering is costly, when ` increases. In t...
PURPOSE Guinea pigs have been increasingly used as an animal model for experimental myopia. Infant guinea pigs are susceptible to recovery from myopia within 2 weeks of form deprivation. This study investigated whether adolescent guinea pigs are susceptible to recovery from myopia after a longer period of form deprivation. METHOD Twenty-two guinea pigs (age of 3 weeks) were randomly assigned ...
When newly hatched Caenorhabditis elegans larvae are starved, their primordial germ cells (PGCs) arrest in the post-S phase. This starvation-induced PGC arrest is mediated by the DAF-18/PTEN-AKT-1/PKB nutrient-sensing pathway. Here, we report that the conserved spindle assembly checkpoint (SAC) component MDF-1/MAD1 is required for the PGC arrest. We identified 2 Akt kinase phosphorylation sites...
The muscle-derived differentiation factor called MDF initiated expression of the catecholamine (CA) enzyme tyrosine hydroxylase (TH) in non-CA neurons isolated from a variety of regions in the rat brain. Specifically, subpopulations of neurons from the striatum, collicular plate, and cerebellum were TH-immunoreactive after an overnight exposure to MDF in culture. The number of immunopositive ce...
The goal of this study was to determine the comparative properties of dry-formed medium density fiberboards (MDF) made from renewable biomass (wheat and soybean straw) and those from conventional soft wood fiber. The MDF properties evaluated were modulus of elasticity, modulus of rupture, internal bond strength, thickness swell, and screw holding capacity. The results show that MDF made from wh...
The study aimed to investigate factors associated with respiratory symptoms in workers in a medium-density fiberboard (MDF) furniture factory in Eastern Thailand. Data were collected from 439 employees exposed to formaldehyde and MDF dust using questionnaire and personal sampler (Institute of Occupational Medicine; IOM). The average concentration of formaldehyde from MDF dust was 2.62 ppm (SD 3...
