The research presents a comparative study regarding the optimization of two bioscouring treatments applied on 50 % of flax+50 % of cotton blended material in presence and absence of the ultrasound energy The treatments optimization was made by using a central, rotatable second order compound program with two independent variables: enzyme concentration and treatment time. The data obtained after determination of the weight loss of the treated samples fabrics were used afterwards for the bioscouring treatments optimization.

Two Independent Variables

Village apparatus is an important factor in the running of the government process in the village. Therefore an analysis is needed to determine the factors that affect the performance of the village apparatus. There are two independent variables in this study, namely; work ethic and work discipline. In the process this study uses village tools in Lumajang District as a population with 64 respondents. Furthermore, for data analysis techniques using multiple linear regression analysis, the results of the analysis show that both work ethic and motivation have a significant effect on the performance of the village apparatus. This is supported by the coefficient of determination of 73.4% so that only 26.6% remains for other variables that affect the performance of village equipment. This research is expected to contribute to the development of studies in management science, especially human resource management so that it can become a reference to further research.

Two Independent Variables

We consider the Cauchy problem for second-order differential operators with two independent variables [Formula: see text]. Assuming that [Formula: see text] is a nonnegative [Formula: see text] function and [Formula: see text] is a nonnegative Gevrey function of order [Formula: see text], we prove that the Cauchy problem for [Formula: see text] is well-posed in the Gevrey class of any order [Formula: see text] with [Formula: see text].
