What a life! No end of changing and building up and pulling down again and jumping about. Such a lot of work may turn out to be really harmful. Oh, I'm dejected just to think of all the people who work and buzz and bumble about, and what it all leads to. I had a cousin once who studied trigonometry until his whiskers drooped, and when he had learnt it all a Groke came and ate him up. Yes, so wi...

In recent years there has been an increasing interest in using high-yield pulp (HYP) as a partial replacement for hardwood bleached kraft pulp (HWBKP) in the production of high-quality fine papers as a cost-effective way of improving the product performance. This study investigated the substitution of HYP for HWBKP and its effect on the Alkenyl Succinic Anhydride (ASA) sizing performance. The r...

Genomic walking PCR was used to obtained a 4,567-bp nucleotide sequence from Caldibacillus cellulovorans. Analysis of this sequence revealed that there were three open reading frames, designated ORF1, ORF2, and ORF3. Incomplete ORF1 encoded a putative C-terminal cellulose-binding domain (CBD) homologous to members of CBD family IIIb, while putative ORF3 encoded a protein of unknown function. Th...

The use of treated pulp mill effluent on eucalyptus plantation appears to be an attractive option for plant nutrition and water supply. It also constitutes a supplementary treatment process and a final disposal option for the mill effluent. This study aimed at the investigation and evaluation of the effects of bleached kraft pulp mill treated effluent on three typical Brazilian soils used for e...

Screen printing originated in China during the Song dynasty (960-1279 CE) and is used today commercial artistic applications. The presented research project describes development of a screen-printing product for studio art improvement paper properties from laboratory small 12-inch machine development, followed by semi production at speed 128 ft/min on 48-inch final paper, showed an throughout p...

The wood of a mature (40-year-old) Eucalyptus globulus Labill tree was characterized at different stem height levels (0%, 10%, 35%, and 50% of total height) regarding pulping, bleaching, and paper properties. Pulp yields increased upwards from 46% to 50%, and Kappa number decreased from 17.5 to 12.3 at 0 and 50% height, respectively. The estimated specific wood consumption ranged from 3.2 m odt...
