Earth-moving machinery. Human physical dimensions of operators and minimum operator space envelope

This chapter argues that women, like foreigners, were subject to having their personhood erased by those who were dominant over them. The chapter begins with an assessment of whether women were considered persons in ancient Israel, addressing in detail the issue of whether they were considered to be property. Responding to previous research on this question, the chapter contends that women were treated in the ways they were not because they were the property of their husbands but because they were subordinates, and their subordination had clear physical dimensions. Just as subordinate men were liable to having their personhood erased in certain situations, the position of having dominance over women as husbands and fathers also entailed the ability to erase women’s personhood through violence in cases of transgression.

This paper develops simplifying entropic models of irreversible closed cycles. The entropic models involve the irreversible connections between external and internal main operational parameters with finite physical dimensions. The external parameters are the mean temperatures of external heat reservoirs, the heat transfers thermal conductance, and the heat transfer mean log temperatures differences. The internal involved parameters are the reference entropy of the cycle and the internal irreversibility number. The cycle’s design might use four possible operational constraints in order to find out the reference entropy. The internal irreversibility number allows the evaluation of the reversible heat output function of the reversible heat input. Thus the cycle entropy balance equation to design the trigeneration cycles only through external operational parameters might be involved. In designing trigeneration systems, they must know the requirements of all consumers of the useful energies delivered by the trigeneration system. The conclusions emphasize the complexity in designing and/or optimizing the irreversible trigeneration systems.
