Savannakhet Province, Lao People’s Democratic Republic (PDR), is a small area that is connected to Thailand, other areas of Lao PDR, and Vietnam via road No. 9. This province has been increasingly affected by carbon dioxide (CO2) emitted from the transport corridors that have been developed across the region. To determine the effect of the CO2 increases caused by deforestation and emissions, th...
We have performed a spectroscopic study of globular clusters (GCs) in the nearest giant elliptical NGC 5128 using the 2dF facility at the Anglo-Australian telescope. We obtained integrated optical spectra for a total of 254 GCs, 79 of which are newly confirmed on the basis of their radial velocities and spectra. In addition, we obtained an integrated spectrum of the galaxy starlight along the s...
The effect of multi-directional forging on the development texture and increase hardness was investigated for a commercial A5052 aluminum alloy, which had an initial with major orientation {001}<100>. Two specimens were prepared: one obtained via (MDF) performed four times at true strain 0.18 each forging, while other prepared unidirectional (UDF) time 0.72. MDF UDF same 0.72 exhibited tendenci...
Os pisos com revestimento de madeira são produtos engenheirados, geralmente produzidos lâminas coladas sobre chapa compensado ou painéis reconstituída, os quais possuem larga aceitação no mercado brasileiro. Neste trabalho, objetivou-se desenvolver um piso composto bambu e MDF, uso tratamento termomecânico, determinar as suas propriedades físicas mecânicas em comparação laminado comercial. As a...
Abstract Medium density fibreboards (MDF) are currently not recycled after service life, but various publications report on recycling by the disintegration of MDF using techniques and properties obtained recovered fibres (RF). In this study, main aim was to put back RF into manufacturing process as closed-loop repeated thermo-hydrolytic disintegration. Compared previous studies, focus with a re...
در این مقاله راجع به بریکت هایی که از نرمه کوک ( که در که در کارخانه ذوب آهن اصفهان تولید شده ) و نیز نر مه زغال سنگ مخلوط با ملاس چغندر ، بنتونیت ، سیمان ، و خاک اره به نسبت مناسب , بعنوان ماده چسبنده در سطح آزمایشگاهی ساخته شده و مورد پژوهش قرار گرفت صحبت می شود از این بررسی چنین نتیجه گیری شد که ، از مواد چسبنده فوق الذکر ، ملاس چغندر برای تولید بریکت های سوخت از نرمه کوک مناسب تر است .
در این تحقیق به بررسی و مقایسه مقادیر بارگذاری کششی و فشاری قطری اتصالهای گوشهای جداشدنی در تخته فیبر دانسیته متوسط (MDF) و تختهخردهچوب پرداخته شده است. نمونههای L شکل به اندازه 20×20 سانتیمتر با 5 تکرار مورد آزمایش قرار گرفتند. در این تحقیق از سه نوع اتصال جداشدنی پرمصرف: فلزی پروانهای، ذوزنقهای و پلاستیکی دربدار توسط دو نوع پیچ MDF و خودکار برای اتصال استفاده گردید. نتایج مطالعه حاضر...
BACKGROUND Cognitive performance is a complex process influenced by multiple factors. Cognitive assessment in experimental animals is often based on longitudinal datasets analyzed using uni- and multi-variate analyses, that do not account for the temporal dimension of cognitive performance and also do not adequately quantify the relative contribution of individual factors onto the overall behav...
Medium Density Fiberboard (MDF) is an engineered wood used in furniture industry as an alternative to solid wood. Bes ides using forest wood and rubber wood as the main source of fiber, oil palm biomass was proven as an excellent substitute. Regardless of any fiber used, identifying its strength level is the main issue. Therefore, prior to releasing processed fiberboards for manufacturing use, ...
In 24 non insulin-dependent diabetic patients [NIDDM-12 with (ND+) and 12 without (ND-) asymptomatic polyneuropathy] in stable metabolic control, and in 12 age-matched controls (C), we studied the functional properties of tibialis anterior muscle (TA) through an electrically elicited contraction. We recorded the surface EMG signal and analysed the median frequency of power spectrum (MDF), the a...
