This thesis examines the possibility to use computerized image analysis for quality control of wood-chips used for pulping. The quality control in this case means controlling the amount of bark in the chips, since bark can create damages in the finished product. At present the chips quality at Stora Enso Packaging Boards, Skoghall Mill is controlled with samples where the amount of bark is eval...

In this study, root bark of Ulmus pumila (U. pumila) was extracted with ethanol, and then the antimicrobial effects were tested on clinically isolated 12 MRSA strains and 1 standard MRSA strain. U. pumila showed antibacterial activities against all MRSA strains. Minimum inhibitory concentration (MIC) of U. pumila root bark against all MRSA strains revealed a range from 125 to 250  μ g/mL. These...

The idea that phytopathogenic fungi associated with tree-killing bark beetles are critical for overwhelming tree defenses and incurring host tree mortality, herein called the classic paradigm (CP), has driven research on bark beetle-fungus symbiosis for decades. It has also strongly influenced our views of bark beetle ecology. We discuss fundamental flaws in the CP, including the lack of consis...

This study investigated speaker sex differences in F2 Locus equations (F2 LEs) based on linearly (Hz) and tonotopically (Bark) scaled formant measurements. F2 data based on English monosyllabic words produced by thirteen women and eleven men were tonotopically scaled [20, 21] and F2 LEs were derived for both the linear and tonotopically scaled formant values. Although the overall sex difference...

amount of information about what contemporaries felt they knew and what they did in actual practice. The first twothirds of the book covers such topics as remedies, diseases, healthy living, surgery and the knowledge, prevention and cure of the plague. And through this Part I, Wear addresses the similarities, differences, continuities and changes reflected in the ideas and practices of learned ...

Subcutaneous treatment of 50% EtOH extract of neem bark (Azadirachta indica A. juss) to male rats at the dose of 10 mg for 30 days caused arrest of spermatogenesis. The diameter of serminiferous tubule, Leydig cell nucleus and epithelial heights of epididymides were significantly reduced (p≤0.001). Sperm motility and density were significantly reduced. Reduced testicular and accessory organ pro...
