Investigating the Resistance Expression Method of Wood Resistance Drill Instruments

چکیده

Abstract Wood density is an important attribute that positively correlated with many wood quality parameters. How to express drill resistance a challenge. In this study, we determined the optimal expression using current, voltage, and power of DC (Direct-Current) motor. Nine blocks crossing over pith, widths heights 2 cm 5 cm, respectively, were obtained from three larch (Larix spp.) trees. The microdensity each block at every 0.1-mm length was measured, average motor recorded when fed forward 0.1 mm by self-manufactured drill. path parallel lengthwise direction block. linear models between subsequently established, model highest R2adj selected resistance. adjusted stepwise regression as 0.2943. This suggests drilling needle expressed or other combination may be optimal.

Effect of chitosan on the mold resistance of wood and its surface properties

In this study, the effect of soluble chitosan, thyme oil and linseed oil on the mold resistance of wood and its surface properties was investigated. Both low and medium molecular weight chitosan with concentration of 1 and 2% were used. Cypress wood samples with dimensions of 20 × 20 × 70 mm and moisture content of 12% were saturated by the preservatives. The results showed that the maximum abs...

buckling of viscoelastic composite plates using the finite strip method

در سال های اخیر، تقاضای استفاده از تئوری خطی ویسکوالاستیسیته بیشتر شده است. با افزایش استفاده از کامپوزیت های پیشرفته در صنایع هوایی و همچنین استفاده روزافزون از مواد پلیمری، اهمیت روش های دقیق طراحی و تحلیل چنین ساختارهایی بیشتر شده است. این مواد جدید از خودشان رفتارهای مکانیکی ارائه می دهند که با تئوری های الاستیسیته و ویسکوزیته، نمی توان آن ها را توصیف کرد. این مواد، خواص ویسکوالاستیک دارند....

Investigating antibiotic resistance in non-clinical environments

There have been many calls for more information about the natural resistome and these have also highlighted the importance of understanding the soil resistome in the preservation of antibiotics for the treatment of infections. However, to date there have been few studies which have investigated the culturable soil resistome, which highlights the difficulties faced by microbiologists in designin...
