Saturn V Booster - The F-1 Engine

On December 20, 196^, NASA announced, The F-l Rocket Engine, the most powerful being developed by the United States, has completed its flight rating test, and is now ready for cluster firings and actual flight. The engine that completed FRT consists of a single thrust chamber, injector and dome, a single direct drive turbopump, a single gas generator, two each fuel pump discharge lines and control valves and also lox pump discharge lines and control valves, and a single start valve. The start valve is the only major engine part requiring electrical energy as a control device. Instrumentation to monitor engine operation during flight also requires electrical energy but is independent of engine operation. This engine system is in accordance with the reliability design concept that highest overall engine reliability is achieved by using the minimum number of parts. The FRT engine resulted from this concept combined with previous Rocketdyne engine experience and advanced metallurgy

Not Kant vs. Scheler, but either Kant or Scheler. From Construction to Foundation of Ethics

Scheler’s moral theory is often presented as a critical reaction to Kantian formalism. The majority of contributions on this topic deals with Scheler’s proposal of an a priori material ethics in contrast with the a priori formal ethics developed by Kant, or with the critical analysis of the eight prejudices ascribed by Scheler to Kant. A very few of them, however, explore their respective foundational attempts to see why such a conflict actually arises. This paper addresses exactly the foundational issue, trying to fulfill this empty space in the literature. In particular, by briefly investigating the third section of the Groundwork of the Metaphysics of Moral and the doctrine of the Fact of Reason depicted by Kant in the second Critique on the one hand and the phenomenological theory of values elaborated by Scheler on the other hand, it will be shown that the disagreement between the two authors should not be ascribed to a real incompatibility, but rather to a different way of conceiving what the foundation of ethics actually is

FACILITATE DELIBERATION. TOWARDS A PROFESSIONALIZATION OF THE BIOETHICAL EXPERT IN THE PUBLIC ARENA.

In an increasingly specialized world, where the production of knowledge and its acquisition have become a collective enterprise, nobody can master all the fields alone. This has led to the proliferation of a myriad of experts, each of whom is specialized in a precise domain or subdomain. Given this picture, it is not surprising that people with training in bioethics are often referred to as \u2018bioethics experts\u2019 and/or \u2018bioethical experts\u2019. However, far from being confined to a specific social dimension, in today\u2019s society bioethicists are a commonplace presence in an ever-increasing range of domains. In recognition of this phenomenon, the aim of this thesis is to explore the so-called issue of bioethical expertise. This means first and foremost exploring two main questions: whether an expertise in the field of bioethics might actually exist and what are, if any, the skills that the bioethical expert is endowed with, in order to understand whether this figure is on a par with professionals of other disciplines. After presenting a general review of the current literature on this issue and briefly indicating the different research paths this research topic might lead to, the focus will be narrowed to dwell on the main research questions this work aims to address: is there a legitimate role for the bioethical expert within the public arena, and, if so, what is this role? Far from being a straightforward question, this issue is further complicated by a vast literature decrying the threat posed by bioethicists with respect to the broader context in which they operate: liberal democracies. In taking these considerations seriously, this dissertation aims to \u2018solve the paradox\u2019 connected with the figure of bioethical expert and to propose a normative model of bioethical expert which aims to be compatible with the tenets of liberal democracies and, in particular, their public decision-making processes. This figure will be defined here as the facilitator of deliberation, thus recognizing the debt it has towards the political theories of deliberative democracy. This work is structured as follows: first of all the theoretical current debate concerning the topic of bioethical expertise is presented. Secondly, by narrowing the focus of investigation I concentrate on the domain in which the bioethical expert proposed here has to operate: public bioethics. The normative proposal of bioethical expert as facilitator of deliberation is then presented, remodelling the former in relation to the already existing figures occupying the public arena. Finally, the results of a preliminary experiment, designed to empirically explore this new figure, are presented and discussed. \u200

"We are the rug hooking capital of the world": understanding Chéticamp rugs (1927-2017)

This thesis is the story of how utilitarian material culture was transformed into a cottage industry, and eventually into high art. Chéticamp rug hooking is an artistic practice, one wrapped up in issues of taste, creativity, class and economics. Rug hooking in Chéticamp rose to prominence in the first half of the 20th century when Lillian Burke, a visiting American artist, set up a rug hooking cottage industry in the area. She altered the tradition to suit the tastes of wealthy patrons, who began buying the rugs to outfit their homes. This thesis examines design in rug hooking focusing on Chéticamp-style rugs. Captured within design aesthetics is what the rugs mean to both those who make and consume them. For tourists, the rugs are symbols of a perceived anti-modernism. Through the purchase of a hooked rug, they are able to bring home material reminders of their moment of experience with rural Nova Scotia. For rug hookers, rugs are a symbol of economic need, but also agency and the ability to overcome depressed rural economic conditions. Rug hooking was a way to have a reliable income in an area where much of the labour is dependent on unstable sources, such as natural resources (fishing, lumber, agriculture etc.). This also meant that rug hooking is closely tied to notions of poverty. The motif-index developed for this thesis by examining several hundred hooked rugs demonstrates that consistent structural elements such as motifs are dependent on context. When used in a comparative manner, it also helps illustrate how often those creating hooked rug designs, whether they were sold commercially as patterns or designs to be used as part of a cottage industry, were sharing and borrowing design ideas throughout North America. The motif-index is a typology and a tool that enables discussion by standardizing language and terminology which allows for comparative examination of hooked rugs from across a variety of traditions

From virtual to real healing: a critical overview of the therapeutic use of virtual reality to cope with mourning

In recent years, virtual reality (VR) has been effectively employed in several settings, ranging from health care needs to leisure and gaming activities. A new application of virtual stimuli appeared in social media: in the documentary ‘I met you’ from the South-Korean Munhwa Broadcasting, a mother made the experience of interacting with the avatar of the seven-year-old daughter, who died four years before. We think that this new application of virtual stimuli should open a debate on its possible implications: it represents contents related to grief, a dramatic and yet natural experience, that can have deep psychological impacts on fragile subjects put in virtual environments. In the present work, possible side-effects, as well as hypothetical therapeutical application of VR for the treatment of mourning, are discussed

3D GEOMATICS TECHNIQUES FOR AN INTEGRATED APPROACH TO CULTURALHERITAGE KNOWLEDGE: THE CASE OF SAN MICHELE IN ACERBOLI'S CHURCHIN SANTARCANGELO DI ROMAGNA

The modern Geomatics techniques, such as Terrestrial Laser Scanner (TLS) and multi-view Structure from Motion (SfM), are gaining more and more interest in the Cultural Heritage field. All the data acquired with these technologies could be stored and managed together with other information in a Historical Building Information Model (HBIM). In this paper, it will be shown the case study of the San Michele in Acerboli's church, located in Santarcangelo di Romagna, Italy. This church, dated about the 6th century A.D., represents a high relevant Romanic building of the high Medieval period. The building presents an irregular square plan with a different length of the lateral brick walls and a consequential oblique one in correspondence of the apse. Nevertheless, the different lengths of the lateral brick walls are balanced thanks to the irregular spaces between the windows. Different changes occurred during the centuries, such as the closing of the seven main doors and the building of the bell tower, in the 11th century A.D., which is nowadays the main entrance of the church. An integrated survey was realized, covering the exterior and the interior. The final 3D model represents a valid support not only for documentation, but also to maintain and manage in an integrate approach the available knowledge of this Cultural Heritage site, developing a HBIM system in which all the mentioned historical, geometrical, material matters are collected

Second international diagnostic accuracy study for the serological detection of west nile virus infection.

Background: In recent decades, sporadic cases and outbreaks in humans of West Nile virus (WNV) infection have increased. Serological diagnosis of WNV infection can be performed by enzyme-linked immunosorbent assay (ELISA), immunoflu- orescence assay (IFA) neutralization test (NT) and by hemagglutination-inhibition assay. The aim of this study is to collect updated information regarding the performance accuracy of WNV serological diagnostics. Methodology/Principal findings: In 2011, the European Network for the Diagnostics of Imported Viral Diseases- Collaborative Laboratory Response Network (ENIVD-CLRN) organized the second external quality assurance (EQA) study for the serological diagnosis of WNV infection. A serum panel of 13 samples (included sera reactive against WNV, plus specificity and negative controls) was sent to 48 laboratories involved in WNV diagnostics. Forty-seven of 48 laboratories from 30 countries participated in the study. Eight laboratories achieved 100% of concurrent and correct results. The main obstacle in other laboratories to achieving similar performances was the cross-reactivity of antibodies amongst heterologous flaviviruses. No differences were observed in performances of in-house and commercial test used by the laboratories. IFA was significantly more specific compared to ELISA in detecting IgG antibodies. The overall analytical sensitivity and specificity of diagnostic tests for IgM detection were 50% and 95%, respectively. In comparison, the overall sensitivity and specificity of diagnostic tests for IgG detection were 86% and 69%, respectively. Conclusions/Significance: This EQA study demonstrates that there is still need to improve serological tests for WNV diagnosis. The low sensitivity of IgM detection suggests that there is a risk of overlooking WNV acute infections, whereas the low specificity for IgG detection demonstrates a high level of cross-reactivity with heterologous flaviviruse
