Manned Mars mission Earth-To-Orbit (ETO) delivery and orbit assembly of the manned Mars vehicle

The initial concepts developed for the in-orbit assembly of a Manned Mars Vehicle and for the Earth-to-Orbit (ETO) delivery of the required hardware and propellant are presented. Two (2) Mars vehicle concepts (all-propulsive and all-aerobrake) and two (2) ETO Vehicle concepts were investigated. Both Mars Vehicle concepts are described in Reference 1, and both ETO Vehicle concepts are described in Reference 2. The all-aerobrake configuration reduces the number of launches and time required to deliver the necessary hardware/propellent to orbit. Use of the larger of the 2 ETO Vehicles (HLLV) further reduces the number of launches and delivery time; however, this option requires a completely new vehicle and supporting facilities

Religion, education and the state: the origins, development and significance of church affiliated universities in Zimbabwe

This thesis explores interactions between government and religious bodies in the evolution of church-related universities in post-independence Zimbabwe. Since the 1980s there has been an increased interest in the direct involvement of religion in university education. It is argued that the new interest by churches in setting up universities is a response to the exigencies of the modern world which regard knowledge as an essential feature in development.A further dimension which this thesis examines is the triangular relationship involving religion, the state, and the university. The three parties have distinct but interrelated agendas and functions. While by definition a university has claim to autonomy and academic freedom, for an institution founded by religion, this creates tension as the institution tries to strike a balance between its identity and its relationship to the church. The question of identity is not confined to churchrelatedness but extends to the role of such institutions in modem Zimbabwe. The study further attempts to locate emerging church affiliated universities in the discourse of endogenisation. The thesis proposes that if the new religious institutions are to have a significant impact, their pragmatic approaches should operate within an African epistemological framework which takes serious account of authentic endogenous knowledge systems

A note on k-plane integral transforms

AbstractLet Π be a k-dimensional subspace of Rn, n ⩾ 2, and write x = (x′, x″) with x′ in Π and x″ in the orthogonal complement Π⊥. The k-plane transform of a measurable function ƒ in the direction Π at the point x″ is defined by Lƒ(Π, x″) = ∝Πƒ(x′, x″) dx′. In this article certain a priori inequalities are established which show in particular that if ƒ ϵ Lp(Rn), 1 ⩽ p $̌nk, then ƒ is integrable over almost every translate of almost every k-space. Mapping properties of the k-plane transform between the spaces Lp(Rn), p ⩽ 2, and certain Lebesgue spaces with mixed norm on a vector bundle over the Grassmann manifold of k-spaces in Rn are also obtained

The Definition and Impact of College Quality

In this paper we are concerned with the characteristics of colleges which serve to increase subsequent monetary incomes of those who attend. Usually, lifetime earnings are explained by variables such as innate ability, experience in the labor force and years of education, although other socio-economic, demographic and occupational data can be inserted to increase the explanatory power of the model. This paper attempts to add a new dimension to the earnings function analysis by hypothesizing the features of colleges which might yield financial payoffs later in life, and then testing to see which of these traits actually do add most to the explanatory power of the traditional earnings function.
