Classed spaces – Harry Anderson
On Tuesday 7th February, our ‘Class, Politics and Culture’ seminar group set off exploring London’s East End. Led by Liza Mckenzie, the aim of the ethnographic walk to take us out the classroom to see the how London is changing, and look at how such changes impact on ideas of space, place, identity and belonging within the East End
The identification and evaluation of differences among promoted, not promoted, and considered for nonpromotion but promoted pupils in third grades.

Studies on Factors Affecting Stored Energy Characteristics of Baby Pigs at Birth and Subsequent Changes During Early Neonatal Life
Studies designed to investigate the factors affecting stored energy levels of baby pigs at birth and changes on energy sources during early neonatal life were conducted over a three year period. During the three years 604 newborn pigs representing 85 different litters were partially or completely analyzed chemically at ages ranging from 0 to 72 hours. Various treatments of the dam during gestation and treatment of the newborn pig were utilized. The treatments used in the different trials were: (1) gestation weight gain of the gilts of either 0 to 10 kg or 10 to 20 kg, (2) energy intakes of 5924, 6183 or 6975 Kcal of metabolizable energy (ME) per day for 10 days prior to farrowing, (3) daily energy intake to meet the resting metabolic requirement of the gilt, resting metabolic requirement plus 2000 Kcal ME per day, for 10 days prior to farrowing, (4) feeding 0 or 800 mg of dichlorvos per sow per day for 21 to 30 days prior to farrowing, (5) administration of 2 g sucrose, orally, and 1 IU insulin, subcutaneously, per kg body weight to pigs at birth and (6) sacrifice and tissue sampling of pigs at 0, 3, 6, 9, 12, 15, 18, 24, 36, 48 or 72 hours of age. Gilts gaining 10 to 20 kg during gestation produced pigs with higher liver glycogen and total body ash and lower liver fat, blood reducing sugar levels and total body fat at birth than pigs from gilts gaining 0 to 10 kg of body weight. Feeding gilts either 5924, 6183 or 6975 Kcal of ME per day for 10 days prior to farrowing had no effect on liver or muscle glycogen, Liver fa or moisture of the neonatal pig. Gilts fed at a level of 2000 Kcal of ME more than their resting metabolic requirement per day for 10 days prior to farrowing produced pigs with a slower growth rate to 72 hr of age than gilts fed either at their resting metabolic requirement or metabolic requirement plus 1000 Kcal per day. Pigs from gilts receiving 800 mg dichlorvos per day for 21 to 30 days prior to farrowing had higher liver glycogen levels and total body ash at birth, lower total body fat and moisture and less body weight gain to 72 hr of age. Administration of sucrose and insulin to the new born pig produced lower serum glucose levels at 3 and 18 hr of age and higher serum fructose levels at 3, 6, 9, 12, 15, 18 hr of age. Chemical analyses of liver, muscle and blood samples for the three years showed the following changes during the early neonatal period: (1) liver glycogen levels decreased from birth (11.5 to 14.9%) to 36 hr of age (3 to 4%) and then increased to 5.0% at 72 hr of age, (2) muscle glycogen decreased steadily from 8.5 to 9.0% at birth to 2.8% at 72 hr of age, (3) liver fat increased from birth (1.0 1.6%) to 12 or 18 hr (2.5 to 2.7%) and then decreased to 72 hr of age (1.6%), (4) liver moisture increased from birth (73%) to 18 hr (77 to 78.5%) and then decreased to 76% at 72 hr of age, (5) liver weight, expressed as a percent of body weight, decreased from 2.7% at birth to2.3% at 18 hr and then increased to 3.2% at 72 hr of age, (6) total reducing sugar content of the blood increased from birth (120 mg per 100 ml) to 12 hr (124 mg per 100 ml), decreased to 118 mg per 100 ml at 18 hr and then increased to 128 mg per 100 ml at 72 hr of age, (7) serum triglycerides increased from 190 mg per 100 ml at birth to 305 mg per 100 ml at 36 hr of age, (8) serum glucose increased from 50 mg per 100 ml at birth to 122 mg per 100 ml at 36 hr of age, (9) serum fructose decreased rapidly from birth (41 mg per 100 ml) to 24 hr of age (4.0 mg per 100 ml) and then decreased slightly to 3.5% at 36 hr of age, and (10) total urine sugar content of the urine decreased from birth to 36 hr of age. Changes in total body composition during the first 72 hr of life were characterized by: (1) decreased moisture content from 82.87% at birth to 79.65% at 72 hr of age, (2) increased fat content from birth (6.73%) to 72 hr of age (20.99%), (3) increased protein content from 54.26% at birth to 56.47% at 24 hr of age and then decrease protein content to 72 hr of age (52.53%), and (4) decreased ash content from 16.4% at birth to 13.74% at 72 hr of age
Techniques used in the F-14 variable-sweep transition flight experiment
This paper discusses and evaluates the test measurement techniques used to determine the laminar-to-turbulent boundary layer transition location in the F-14 variable-sweep transition flight experiment (VSTFE). The main objective of the VSTFE was to determine the effects of wing sweep on the laminar-to-turbulent transition location at conditions representative of transport aircraft. Four methods were used to determine the transition location: (1) a hot-film anemometer system; (2) two boundary-layer rakes; (3) surface pitot tubes; and (4) liquid crystals for flow visualization. Of the four methods, the hot-film anemometer system was the most reliable indicator of transition

Michael John Robert Fasham. 29 May 1942 — 7 June 2008
Professor Michael Fasham played a pioneering role in the development of marine ecosystem models for the study of nutrient and carbon cycling in the ocean. He is articularly celebrated for his famous Fasham–Ducklow–McKelvie model, which was the first of its kind to separate new and regenerated forms of nutrient, as well as including microbial recycling pathways. Fasham’s models provided key understanding of the links between primary production, carbon cycling and export (of organic matter from the surface to deep ocean) based on both deep and insightful parameterization inspired by his many collaborations with leading experimental and field biologists of the day, and by his expert use of data for model calibration and validation. He had the ability to see the big picture, linking observation and models to achieve a unified understanding of system dynamics. As well as the direct contributions of his own science, Fasham played a pivotal role in steering the international scientific agenda, notably his leadership of the Joint Global Ocean Flux Study which had the aim of understanding ocean carbon cycling and sinks via the coordination of extensive field programmes, synthesis and modelling. He will be remembered by those who knew him for his openness, enthusiasm and modesty, a man who was fun to know and to work with and who loved the thrill of scientific adventure and discovery
