this research aims to assess the physicochemical properties, image features, textural and sensory qualities of dark chocolate made using coffee silver skin as a cocoa powder replacement which was substituted for 25%, 50%, 75% and 100% of the cocoa powder (by weight) in chocolates. the results indicated that there was significant differences between the chocolates prepared using 100% coffee skin...
Use of bacteriophage lambda recombination functions to promote gene replacement in Escherichia coli.
Replacement of Escherichia coli's RecBCD function with phage lambda's Red function generates a strain whose chromosome recombines with short linear DNA fragments at a greatly elevated rate. The rate is at least 70-fold higher than that exhibited by a recBC sbcBC or recD strain. The value of the system is highlighted by gene replacement with a PCR-generated DNA fragment. The deltarecBCD::Plac-re...
To establish their role in monitoring patients receiving thyroxine replacement biochemical tests of thyroid function were performed in 148 hypothyroid patients studied prospectively. Measurements of serum concentrations of total thyroxine, analogue free thyroxine, total triiodothyronine, analogue free triiodothyronine, and thyroid stimulating hormone, made with a sensitive immunoradiometric ass...
This paper explores the welfare consequences of unemployment insurance when private insurance markets are subject to enforcement frictions that limit debt accumulation, endogenously determining individual borrowing limits as a function of the length of unemployment. Reducing the replacement rate in the model initially increases borrowing, as the value of default declines significantly. As the r...
BACKGROUND Natural environments, including green spaces, may have beneficial impacts on brain development. However, longitudinal evidence of an association between long-term exposure to green spaces and cognitive development (including attention) in children is limited. OBJECTIVES We evaluated the association between lifelong residential exposure to green space and attention during preschool ...
A new component replacement analysis method to solve asset replacement problems for complex electricity distribution systems is developed. In the present model a Taylor series expansion is used to approximate the associated opportunity cost for each component in the system. The method is based on an iterative dynamic programming and integer programming methods to obtain optimal system-level com...
This paper reviews the literature on the determinants of entrepreneurial activity and investigates to what extent differences in the population, business environment and cultural values contribute to explaining differences in entrepreneurial activity across Swedish municipalities. Individual characteristics and business environment are the most important factors in explaining entrepreneurial ch...
in this study, the effects of various concentrations of nacl and kcl and partial replacement of nacl withkcl on the growth characteristics of l. monocytogenes were evaluated. it was found that l. monocytogenescan grow in the presence of 1-9% nacl and 1-11% kcl. the higher the concentration of salt used, the longerthe lag phase induced. in addition, it was observed that l. monocytogenes tolerate...
