    Notes: Abstract. The immune system has evolved several mechanisms that provide lymphocytes with the intelligence to ignore self proteins while attacking foreign pathogenic agents. Notably, B and T lymphocytes that encounter self antigen at either the inappropriate levels or affinity are usually instructed to perish or become anergized. However, the presence of autoimmune disease suggests that the induction of self tolerance is not foolproof. In fact, autoreactive cells are now found to be normal inhabitants of the B and T lymphocyte repertoire. This review examines how foreign peptides which resemble self proteins can elicit autoimmunity that is amplified to many sites on a target autoantigen. In particular, B lymphocytes initiated by foreign molecular mimics can process and present self peptides in the shaping of autoimmune T cell responses.

    Notes: Abstract The water-soluble organic C in composted manure contains a portion of labile C which can stimulate soil microbial activity. The objective of this experiment was to evaluate the effects of water-soluble organic C extracted from composted dairy manure on C mineralization in soil with different textures. Three soils with textures varying from 3 to 54% clay were amended with 0 to 80 mg water-soluble organic C kg−1 soil extracted from a composted dairy manure and incubated for 16 weeks at 23°C. The total amount of C mineralized was greater than the amount of C added in the three soils. Differences in mineralizable C with and without added water-soluble organic C were approximately 13–16 times, 4.8–8 times, and 7.5–8 times greater than the amount of C added to clay, loam, and sand soils, respectively. The results of this experiment suggest that immediately following composted manure applications, C mineralization rates increase, and that most of the C mineralized comes mainly from the indigenous soil organic C pool.

    Management-induced change in labile soil organic matter under continuous corn in eastern Canadian soils (1997)

    Notes: Abstract Soil samples taken from four experimental sites that had been cropped to continuous corn for 3–11 years in Ontario and Quebec were analyzed to evaluate changes in quantity and quality of labile soil organic carbon under different nitrogen (N) fertility and tillage treatments. Addition of fertilizer N above soil test recommendations tended to decrease amounts of water-soluble organic carbon (WSOC) and microbial biomass carbon (MBC). The quality of the WSOC was characterized by 13C nuclear magnetic resonance and infrared spectrophotometry and the results indicated that carbohydrates, long-chain aliphatics and proteins were the major components of all extracts. Similar types of C were present in all of the soils, but an influence of management was evident. The quantity of soil MBC was positively related to the quantities of WSOC, carbohydrate C, and organic C, and negatively related to quantities of long-chain aliphatic C in the soil. The quantity of WSOC was positively related to the quantities of protein C, carbohydrate C, and negatively related to the quantity of carboxylic C. The quantity of soil MBC was not only related to quantities of soil WSOC but also to the quality of soil WSOC.

    Distribution of Liquid-Solid Heat Transfer Coefficient among Suspended Particles in Vertical Holding Tubes of an Aseptic Processing System (1998)

    Notes: Mass transfer coefficients between sucrose coated particles and water as the suspending fluid, were measured to obtain values of the heat transfer coefficient by analogy with mass transfer. In a vertical holding tube configuration, the mass transfer coefficient spanned considerable range for those particles with comparable residence time. At Reynolds number 26100, the average mass transfer Sherwood number expressed in terms of residence time was Sh= -110.4t+215.1, and it scattered normally with standard deviation 19.2. The results indicated that heat transfer coefficients vary among particles with different residence times and may be significantly different even for particles with the same residence time.

    Crystallization Kinetics of Alpha-Lactose Monohydrate in a Continuous Cooling Crystallizer (1990)

    Notes: The crystallization of alpha-lactose monohydrate in a continuous cooling crystallizer was investigated at various temperatures and super-saturations. The population balance model was used to analyze the product crystal size distribution as determined by the Coulter Multi-Sizer for each condition studied. Nucleation and growth values were thereby determined for each temperature and supersaturation. Kinetic models were then developed for both nucleation and growth to demonstrate the effects of the operating parameters. The results showed that the nucleation process had a temperature dependence with an activation energy of 17.0 kcal/mole and that nucleation increased with the 1.9 power of supersaturation and the 1.0 power of the suspension density (mass of crystals). The growth process was found to have a temperature dependence with an activation energy of 22.1 kcal/mole and to be a second order function of the supersaturation.

    Growth Rate Dispersion Effects on Lactose Crystal Size Distributions from a Continuous Cooling Crystallizer (1991)

    Notes: The continuous crystallization kinetics for lactose have been determined. Specifically, a model incorporating the effects of growth rate dispersion (GRD) on particle dynamics has been employed to determine continuous crystallization kinetics from experimentally determined size distributions. The existence of GRD was verified by the excessive number of fines (〈 50 μm) observed. Crystal size distributions were successfully modeled using a two component rate distribution indicating the existence of two distinct types of nuclei. These could be classed as fast-growers (product crystals) and slow-growers (fines). Nucleation and growth kinetics of these populations were determined and compared to other methods of determining kinetics.
