Strand substitution was evaluated for the core of OSB with chips produced by grinding of recycled particleboards and wood waste. All the boards manufactured under laboratory conditions having a share of small chips in the core had high mechanical parameters, thus meeting the requirements of the standard for OSB/3. No significant effect was found of the applied modification of the core on bendin...

Tiap negara tentu memiliki hak otonomi dalam menentukan arah kebijakan luar negeri, sesuai dengan kepentingan nasionalnya, tak terkecuali yang terkait migrasi internasional. Australia di tahun 2013 mencanangkan Operation Sovereign Borders (OSB) menghentikan kedatangan para irregular migrant, termasuk pencari suaka. Kebijakan ini banyak disoroti karena dianggap melanggar prinsip non-refoulement ...

Black spruce is widely used for lumber production in Eastern Canada, and it has the potential to replace trembling aspen paper birch oriented strand board (OSB) manufacturing. This study evaluated bending modulus of elasticity (MOE) rupture (MOR), internal bond (IB), thickness swelling (TS) OSB panels made from black strands how they were affected by geometry. All met CSA O437 (1993) standard c...

Mouse blastocysts were microsurgically injected with embryonal carcinoma cells from in vitro teratocarcinoma cell lines C17, C86, SIKR-OSB, and PCC3/A/I. The embryos were allowed to develop to term and the resulting offspring were analysed for chimaerism using coat colour markers and isozyme differences of the enzyme glucose phosphate isomerase. When injected into blastocysts, cell line C86 pro...

This paper describes a multichannel super-heterodyne signal analyzer, called the Spectrum Analysis Solution (SAS), which performs multi-purpose spectrum sensing to support spectrally adaptive and cognitive radar applications. The SAS operates from ultrahigh frequency (UHF) to the S-band and features a wideband channel with eight narrowband channels. The wideband channel acts as a monitoring cha...

The flexural creep behavior of oriented strandboards (OSB) fabricated with mixed high, density hardwood flakes was investigated. Three types of adhesives, liquid phenolic-formaldehyde (LPF), melamine modified urea-formaldehyde (MUF),.and LPF (face)/MUF (core) were chosen in this investigation. The resin contents (RC) used were 3.5 percent and 5.0 percent. The flakes prepared from white oak, sou...
