Abstract:

Our culture abhors the world.Yet Quicksand is swallowing the duellists; the river is threatening the fighter: earth, waters and climate, the mute world, the voiceless things once placed as a decor surrounding the usual spectacles, all those things that never interested anyone, from now on thrust themselves brutally and without warning into our schemes and manoeuvres (Michel Serres, The Natural Contract, p 3). When Michel Serres describes culture's abhorrence of the world in the opening pages of The Natural Contract he draws our attention to the sidelining of nature in histories and theories th

Abstract:

State of the art conductivity equipment has been used to measure deuterium isotope effects on the molar conductivity of strong electrolytes in the temperature range of 298 K to 598 K as a means of exploring solvation effects under hydrothermal conditions. Individual ionic contributions were determined by extrapolation of published transference number data to elevated temperature. The temperature dependence of the Walden product ratio indicates that there is little difference in the transport of ions between light and heavy water . Excess conductivity observed in hydrogen and deuterium compound

Abstract:

Evidence is considered here for the utilization of domestic farm and companion animals for products other than meat, for example goat horns and calf and cat skins. Selection pressures driving changes in the stature of cattle are suggested to reflect environmental changes from the Medieval Warm Period to the Little Ice Age. An example of catastrophic cattle mortality is examined with regard to the difficulty of establishing the causative effect, the sex ratio of the bodies, and the impact on the manorial farm. Routine disposal of inedible carrion is discussed with regard to urban disposal of ho

Abstract:

This chapter examines the changes in the source material, script, and film of Foreign Correspondent wrought by the Production Code censors. The original source material was a memoir, Personal History, by Vincent Sheean, which was purchased by producer Walter Wanger. The Production Code office advised Wanger that the property would be unsuitable for filming, since it depicted incidents that might offend Nazi Germany and thus would violate the Neutrality Act. Wanger took the idea of a foreign correspondent, and little else, from the Sheean book and created an espionage thriller in which the country served by the villainous spies is unnamed. Alfred Hitchcock was hired on loan-out from Selznick, and before the film was completed, war had broken out in Europe. Siding with Britain, screenwriter Ben Hecht wrote a final scene in which star Joel McCrea pleaded in a radio broadcast for American involvement in the war effort.

Abstract:

By February of 1939, Motion Picture Pictures and Distributors Association (MPPDA) President Will Hays argued that movies needed more realism connecting to the types of problems that face average Americans. With growing anti-Nazi sentiment in Hollywood, the release of Confessions of a Nazi Spy on May 6<sup>th</sup> would become a watershed moment for an industry largely cautious of how they should approach the growing unrest in Europe. At the same time, Hitler’s Minister of Propaganda, Joseph Goebbels, discontinued the shipment of official Nazi war films to the United States. Producer Walter Wanger and radio journalist Jimmie Fidler took to blows in the press. Wanger claimed the Hollywood press was a joke while Fidler defending his work. In February 1940, MPPDA president Will Hays sent out a report commending the cultural importance of movies during the 1930s as “exposing the tragedy of war.”

Abstract:

The term ‘oral cancer’ encompasses all malignant neoplasms affecting the oral cavity. The majority, greater than 90%, are squamous cell car¬cinomas. The remainder are uncommon and comprise minor salivary gland adenocarcinomas, malignant melanoma, sarcomas, haemato-logical malignancies, and metastases to the oral cavity from cancers at other sites. Oral squamous cell carcinoma is a malignant epithelial neoplasm that arises from the lining mucosa of the oral cavity. The tumour shows vary¬ing degrees of squamous differentiation and is characterized by invasion of local structures and metastasis to regional lymph nodes, followed by metastasis to other organ systems (e.g. lungs and bones) later in the course of the disease. Epidemiological data pertaining to oral cancer can be difficult to evalu¬ate because of variations in the methods of data collection (Box 3.1). Notwithstanding these confounding variables, a database produced by the International Agency for Research on Cancer (GLOBOCAN), esti-mated there were over 400,000 new cases of lip, oral, and pharyngeal cancer worldwide in 2012, placing the disease in ninth position with breast, prostate, lung, colorectal, cervical, stomach, liver, and uterine cancer being more common. These data suggest that oral cancer is uncommon, but there are enormous variations worldwide. Whereas oral cancer is relatively uncommon in the UK, accounting for 2% of all cancers, in India and parts of South-East Asia it is the most common malignant neoplasm and accounts for around a third of all cancers. Furthermore, the incidence rates for large countries, such as India and the USA, conceal regional and ethnic variations. For example, incidence rates tend to be higher in urban as opposed to rural communities, and in the USA are higher for blacks than whites. In the United Kingdom, inci¬dence rates are slightly higher in Scotland than in England and Wales. In the United Kingdom the incidence of oral cancer is 9 per 100,000 of the population, which represents around 6,800 new cases per annum. The disease is more common in men than in women; the male:female ratio is currently 2:1. Oral cancer incidence increases with age, and the majority of cases (greater than two-thirds) are diagnosed after the age of 50 years old; less than 5% occur in individuals below the age of 40 years old.

As a core part of the aero engine casing, the thin-walled tube with large diameter usually formed by sheet hydroforming presents high forming precision and forming quality. In this paper, the appropriate hydraulic pressure and blank holder force should be identified to control the wall thickness uniformity of N08811 alloy tube with large diameter. Firstly, the stress-strain curve of this material at room temperature is obtained from deep drawing tests. Subsequently, within the allowable range of springback and wrinkling errors, finite element simulation and the uniform test design are performe

Abstract:

In many advanced combustor concepts, such as the RQL (rich-quench-lean) combustor, the requirement of low NOx emission makes film cooling of the hot gas path surfaces undesirable. Double-walled structures with relatively low aspect ratio (height/width) rectangular passages and with well-controlled thin hot gas side metal walls are an alternative to film cooling. The additional application of other cooling techniques, such as impingement and surface enhancements, make efficient use of the limited cooling air available. However, the use of cooling channels to increase heat transfer coefficients

Abstract:

This paper presents how laser milling can replace conventional milling for producing selected features in thin-walled structures of space instrument parts. Example parts are shown. In the final stages of the manufacturing process the produced thin-walled structures require special attention to avoid vibration, unwanted deformation and even catastrophic destruction of the part. This requires careful planning of machining operations and fixture design which in turn can take considerable time. Laser milling is a slow material removal process. It is generally used only for finishing features that

Abstract:

The twisting of flat bars to create the shape of an auger has been used by blacksmiths for many centuries. Easily recognizable examples of such work include twisted square rods used in wrought iron gates, and hand crafted twist drills. To this day, a large variety of long drills used in the mining industry are created by twisting flat bars of appropriate cross-section. In all of these examples, the edges of the material form a helical pattern which may be characterized by the diameter to pitch ratio. In practice, a pitch ratio of unity is typical, as this ensures sufficient axial motion of mat

Abstract:

Flow forming is one of the cold forming processes which is mainly used to produce thin-walled high-precision tubular components. A three dimensional coupled-field thermo-mechanical finite element model for staggered three-roller backward flow forming of a cylindrical workpiece of MDN-250 maraging steel has been developed using Abaqus/Explicit. In this model, the effect of tip radius of the rollers and friction between the rollers and the workpiece has been considered. The bottom of the workpiece is fixed in the axial direction so that diametral reduction and the axial elongation can be studied

The determination of stress intensity factors (SIF) and crack opening area or displacements (COA or COD) is important constituent when performing the “leak before break” analysis of piping systems in NPPs. The tabulated parametrical results of their calculation are widely presented in modern scientific and normative literature. Nevertheless, there is one aspect of crack behavior, at least in thin walled pipes, which still had not obtained its due attention. We mean here the geometrically nonlinear effect, which can be the big enough to be accounted for in practical applications. It is consider

Abstract:

It has been recognized that heat-transfer fluids used to convey thermal energy produced by one device to another can exhibit significant increases in thermal conductivity with the addition of highly conductive particles. Suspensions of nano- and micro-particles have attracted the most recent interest because of their enhanced stability against sedimentation, reduction in potential for clogging a flow system, as well as the tantalizing possibility of unexpected enhancements in thermal conductivity that have been reported in some experiments. Among various suspensions, considerable attention has

Probe is a key part of atomic force microscopy (AFM) and the curvature radius of its tip limits the lateral resolution. Furthermore, as an expendable, its life has a direct effect on operation cost. Single-walled carbon nanotubes (SWNTs) are ideal materials for the probe tips used in atomic force microscopy (AFM), since they have intrinsically small diameters, high aspect ratios and unique wearability. Herein, the fabrication of AFM SWNT tips is systemically investigated, including mechanical method and direct growth method. In the former, substrates with isolated SWNTs are first prepared by c

Abstract Laser Powder Bed Fusion (L-PBF) enables the production of complex metallic parts. Processes using pulsed wave (PW) laser radiation have been proven to be well suited to build thin-walled honeycomb structures. However, the behavior of these structures under load conditions remains mostly unexplored. The objective of this paper is to characterize L-PBF produced honeycombs by investigating their rub and leakage performance. A pulse modulated process based on previous studies is optimized for productivity and used to build L-PBF test samples out of Inconel 625 (IN625). The honeycomb cell
