The purpose of this paper is to investigate COVID-19 as a super crisis in the design and management of places.

This theory-driven work outlines why and how, by treating COVID-19 as a super crisis, the immunological view rises in priority and swiftly ushers in short- and long-term implications for space design and place management.

First, this paper looks at the short-term impact of COVID-19 upon space and place management in addressing how porous bubbling, stippling and flexible curtaining respond to immediate retrofitting needs during the pandemic. Using the concept of COVID-19-induced collective trauma, this paper draws attention to health-care facilities, schools, workplaces, commercial buildings and public outdoor spaces. These sites require short-term improvisation in place and space design and will, where the collective trauma of COVID-19 leaves strong traces, require long-term redesign and rethinking.

As a super crisis, COVID-19 generates contradictions in the existing trend in space and place studies from the notion of space and place as a container to one focusing on “flow.” A focus on flow highlights a focus on space and place as adaptable to changes in flow, especially as augmented and mediated by technology.

This treatment of COVID-19 as a super crisis is intended to stimulate the design and management of spaces and places in the post-COVID-19 period.

Provides basic steps and general guidelines for the correct use of plaster and render. Includes suggestions of several preparations available to aid this process.

It is probably true to say that the general health of children in this country is better today than it has ever been. Unfortunately, however, the health of one part of our childrens bodies — their mouths — gives cause for grave concern.

The conventional representation of a laminated packet of electrical sheet steel as a homogeneous but anisotropic material is extended by treating any butted joints in the packet as a distinct homogeneous, two‐dimensionally nonlinear, material. Its magnetic characteristics are derived from the energy increment that results from closing the gap, obtained by solving the two‐dimensional field problem in the gap region. This technique is rigorously valid for any anhysteretic, nonlinear, anisotropic material.

Paint and Residue Remover. Magnus 701‐M is a newly formulated solvent compound containing its own seal for cold paint stripping, removal of residues from rubber matrices and the removal of carbonised fuel and oil residues. Work to be cleaned is completely immersed in the solvent itself and should not be allowed to project up through the seal. When sludge accumulates, the solution is allowed to settle overnight and then poured off into another container so that the sludge can be removed from the tank. The entire solution is reused so that the ratio of seal remains constant. CT 1126

The VDU or visual display unit is one of the most pervasive manifestations of technological change. It is also the one which has aroused the most controversy and, at times, misinformation about possible adverse effects on the health of users. As VDU's become increasingly common in the workplace it is important to examine these allegations and consider their veracity.

A purely theoretical approach has been found to be of limited value in the solution of practical Pattern Recognition problems. Difficulties arise when relating infinite mathematics to reality, e.g. “algorithmic convergence” must be replaced by a vaguer notion of “satisfactory performance”. Experimentation has been used to study this and related problems: a) Learning in noise; b) Similarity of classifiers; c) Instability of classifiers; d) Relating infinite‐sample analysis to finite data sets (reference to pdf estimation). Finally, the system requirements for effective experimentation are discussed.

THE originality of the Escher Wyss airscrew, which has been adopted by the Swiss Air Force, is based on the fact that its conception has, since its inception, taken into account all the requirements of a modern variable pitch airscrew. These conditions may be summarized as follows, that the airscrew must normally ensure automatic control at constant engine speed, adapting itself to every condition of flight, and that it should provide, when required, for operation as an aerodynamic brake, and be capable of being moved to the fully feathered position. The essentially mechanical problems, such as the anchorage of the blades in the hub and the design of the pitch control mechanism, must naturally find correct solutions to ensure reliability, together with that simplicity of control which is an essential property of all modern aircraft components.

Introduction There is more than sufficient information available to consultant, design, production and works engineers with respect to protective paint systems for the outside of vessels, but a very limited amount of literature readily accessible when one considers internal protection. Although BS CP 3003, and to some extent CP 2008 with BS 570. 2594, 2654 and 4950 assist with basic concepts, it has become apparent that many engineers would welcome brief non‐technical details of the range of linings available.
