An experimental study was carried to find out the degradability of black liquor of pulp and paper mill wastewater for biomethanogenesis in continuous stirred tank reactor (CSTR) and followed by activated sludge process (ASP). Continuous stirred tank reactor was used in present study for anaerobic digestion of black liquor, while completely mixed activated sludge system was used for aerobic dige...

During the years 1942 through 1945 the author was given the assignment of directing a research program on fat formation in yeast. The work resulted in the first full-scale production of a fat-enriched yeast from sulfite liquor in 1944, and a summary of the data obtained was published (Schulze, 1951). The yeast was being produced at one of the largest paper mills in Germany. The process used was...

In present investigation the biological leaching of aluminum by isolated fungi from red mud, the main waste product of the alkaline extraction of Al from bauxite was studied. Biological leaching experiments were carried out using indigenous, date and orange specimen fungi, Aspergillus Niger, Penicillium simplicissimum notatum. Savored Dextrose chloramphenicol Agar (SDA) wa...

This paper describes the design of a Bayer filter with smooth hue transition using the System Generator for DSP. We describe and compare experimentally two different designs, one based on a MATLAB implementation and the other based on a modification of the Bayer filter using bilinear interpolation. Keywords—Bayer array, Demosaicing, FPGA, Interpolation.

To identify Kraft liquor effects on spermatogenesis and sperm motility of Caspian kutums by using in vitro culture, the fish testis was incubated with 5, 10 and 15 % (V/V) of liquor for 3 and 6 days. The percentage of motile spermatozoa and its total duration were also measured. Adverse effects on testicular cells were more apparent with the increase of liquor concentrations. The mean size of s...

three samples were collected over an eight hour period on August 25, 2005 and combined into one composite sample. Raw green liquor was a two-sample composite because of a change that occurred in recovery boiler operation. Lime rock was a composite sample collected May 19, 2005. Pulp production on August 25, 2005 was 565 ADT. Results are given in Tables I and II. Samples for the mill trial were ...
