The resupply interface mechanism RMS compatibility test

Spacecraft on-orbit servicing consists of exchanging components such as payloads, orbital replacement units (ORUs), and consumables. To accomplish the exchange of consumables, the receiving vehicle must mate to the supplier vehicle. Mating can be accomplished by a variety of docking procedures. However, these docking schemes are mission dependent and can vary from shuttle bay berthing to autonomous rendezvous and docking. Satisfying the many docking conditions will require use of an innovative docking device. The device must provide fluid, electrical, pneumatic and data transfer between vehicles. Also, the proper stiffness must be obtained and sustained between the vehicles. A device to accomplish this, the resupply interface mechanism (RIM), was developed. The RIM is a unique device because it grasps the mating vehicle, draws the two vehicles together, simultaneously mates all connectors, and rigidizes the mating devices. The NASA-Johnson Manipulator Development Facility was used to study how compatible the RIM is to on orbit docking and berthing. The facility contains a shuttle cargo bay mockup with a remote manipulator system (RMS). This RMS is used to prepare crew members for shuttle missions involving spacecraft berthing operations. The MDF proved to be an excellant system for testing the RIM/RMS compatibility. The elements examined during the RIM JSC test were: RIM gross and fine alignment; berthing method sequence; visual cuing aids; utility connections; and RIM overall performance. The results showed that the RIM is a good device for spacecraft berthing operations. Mating was accomplished during every test run and all test operators (crew members) felt that the RIM is an effective device. The purpose of the JSC RIM test and its results are discussed

The The Pearl Effect: African American’s Continuous Push for Well-Being

Consider this question: If happiness is found in the pursuit of a goal, could it be that an oppressed group, that is eternally in a struggle for something better, could have a subconscious and profound relationship with well-being? Is it possible that the human spirit finds ways to survive and thrive with pride regardless of the oppression? The spirit is unique. It survives independently of the oppression with no goal to emulate. Flourishing in the black community is long under-identified and misunderstood. This is primarily due to the lens from which history has analyzed it. Due to the white lens through which we see and judge most things, inequality prevails in America, and propagates a negative message of trauma for African Americans; that they are an oppressed group and nothing more. Even joy is exaggerated and misplaced as an aid to white supremacy through the mistral stereotype, a happy slave grateful for his or her inferior position in society. As Mia Bay (unpublished) asserts, this creates a problematic dichotomy of where African Americans fit in with the flourishing discussion. This paper offers a different lens through which to define thriving in the black community under a new trait, the ‘pearl’ or essence of an oppressed community. Furthermore, it offers an original theory, ‘The Pearl Effect’, which is an original term that I have coined to describe the capacity of individuals or groups to create something positive or of beauty in the face of insurmountable odds and oppression. It is exemplified by the African American community embedding their essence into positive institutions as a resilient act in the face of continuous oppression. It provides examples of the institutions that throughout history personified the Effect and created opportunities for the black community to exhibit the ‘pearl’ trait and experience flourishing, specifically the Black Church, the Harlem Renaissance, and Hip Hop

Developing parasite control strategies in organic systems

This report was presented at the UK Organic Research 2002 Conference. Organic farmers have taken a lead in attempting to reduce dependence on pharmaceutical control of parasites in farmed livestock. Focussing on management and nutrition, the objective of this research is to further develop control strategies, which can support and increase the flexibility of clean grazing systems for sheep and cattle. The approach has been to combine on-farm epidemiological studies, with replicated experiments, in order to develop and demonstrate better systems of control applicable to UK organic farms. Preliminary data from the first years' epidemiological studies are presented in this paper

Cumbria Economic Bulletin - September 2010

The Bulletin is jointly produced by the Centre for Regional Economic Development (CRED), at the University of Cumbria in Carlisle, and the Cumbria Intelligence Observatory (CIO). The aim of the Cumbria Intelligence Observatory (CIO) is to bring together existing research and analysis resources throughout Cumbria, working jointly with partners to provide information and intelligence for Cumbria. The Bulletin is intended to contain data relevant to the County for the benefit of a broad readership, but especially for policy makers, industrialists and academics

Obtaining Maxwell's equations heuristically

Starting from the experimental fact that a moving charge experiences the Lorentz force and applying the fundamental principles of simplicity (first order derivatives only) and linearity (superposition principle), we show that the structure of the microscopic Maxwell equations for the electromagnetic fields can be deduced heuristically by using the transformation properties of the fields under space inversion and time reversal. Using the experimental facts of charge conservation and that electromagnetic waves propagate with the speed of light together with Galileo invariance of the Lorentz force allows us to introduce arbitrary electrodynamic units naturally.Comment: 11 page
