The all-Bugatti Plateau Maurice Trintignant was among the highlights at Angoulême’s Circuit des Remparts on 20 September, a total of 17 Type 35s, 37s and 51s producing a close race over the tortuous hillside circuit. Robert Spencer won from Gregory Ramouna and Bo Williams, all driving 35Bs, while further down the field was the Type 35 driven by 84-year-old Count Léo de Malet Roquefort. The Plateau Wimille provided an eclectic array of entrants and was topped by Rob Cobden’s 1937 Riley special. Edwardian giants such as Tony Lees’ 1913VauxhallViper Special and Andrew Howe-Davies’ 1911 SCATTarga Florio provided much of the…

Cause souring of alcoholic beverages and fruit juices and used to produce vinegar (acetic acid). Can also spoil some fruits (rot). Widely distributed in plants and in places where alcohol fermentation occurs. Important species: Acetobacter aceti. Acinetobacter. Rods (1 × 2 μm); occur in pairs or small chains; show twitching motility because of the presence of polar fimbriae; strictly aerobic and grow between 20°C and 35°C. Found in soil, water, and sewage.

The microbial groups important in foods consist of several species and types of bacteria, yeasts, molds, and viruses. Although some algae and protozoa as well as some worms (such as nematodes) are important in foods, they are not included among the microbial groups in this chapter. Some of the protozoa and worms associated with health hazards, and several algae (fish and shellfish poisoning) associated with health hazards and bioprocessing (sources of vitamins, single-cell proteins), are discussed in Chapters 17 and 28. Bacteria, yeasts, molds, and viruses are important in food for their ability to cause foodborne diseases and food spoilage…

Three tests are recommended for use in initial screening for possible bleeding disorders:14-16 activated partial thromboplastin time (aPTT), prothrombin time (PT), and platelet count (Fig. 25.4). If no clues are evident as to the cause of the bleeding problem and the dentist is ordering the tests through a commercial laboratory, an additional test can be added to the initial screen: thrombin time (TT).14-16 Patients with positive results on screening tests should be evaluated further so that the specific deficiency can be identified and the presence of inhibitors ruled out. A hematologist orders these tests, establishes a diagnosis that is based…

The use of cryoprecipitate, some factor VIII concentrates, and fresh-frozen plasma carries several important risks. For example, transmission of hepatitis B virus (HBV), HCV, and HIV may occur.45 In the 1980s, more than 90% of multiply transfused patients with hemophilia became HIV positive, with the subsequent development of acquired immunodeficiency syndrome (AIDS). Many of these patients have died from the disease. The advent of sterile concentrates together with rigid donor testing begun in 1985, and the availability of recombinant products, has greatly reduced the risk of HIV infection through blood product administration. AIDS cases associated with hemophilia B has been…

The value of a function of a single variable is written fx, where f is the function and x is the variable. We assume that both x and fx are real numbers and that for each value of x there is only one value fx. Technically speaking this makes f a ‘single real-valued function of a single real variable’, but we shall try to avoid such technical vocabulary where possible. Basically, it means that we can draw a graph of the function, with the values x along the horizontal axis and the corresponding values fx along the vertical axis, and…

This year’s Pistons and Props fixture, held at Sywell Aerodrome on 26-27 September, proved to be a richly varied gathering, with entertainment for all tastes and a fine selection of vehicles. With its period buildings, the Northamptonshire airfield allows enough space for more than just a static show, and visitors could enjoy the spectacle of drag races, karting, and demonstrations of singleseaters, motorcycles and Group B rally cars on the mile-long runway. The drag racing in particular attracted good crowds, with the vehicles ranging from classic ‘rails’ to manic Fiat 126s and Don Scott’s Plymouth Superbird. Plane-lovers had all they…

All healthy animals carry a complex microbial flora, part of which may be very specialized and adapted to growth and survival on its host, and part of which may be transient, reflecting the immediate interactions of the animal with its environment. From a topological point of view, the gut is also part of the external surface of an animal but it offers a very specialized environment and the importance of the human gut flora will be dealt with in Chapter 6 The surfaces of humans and other animals are exposed to air, soil and water and there will always be…
