Defences of racial anti-realism typically proceed by establishing that nothing possesses the descriptive characteristics associated with the term ‘race’. This leaves them vulnerable to the externalist challenge that the descriptive meaning of ‘race’ is subject to revision based on discoveries about the nature of its referent. That referent is, according to constructionist realists, the groups we call races (the R-groups). Anti-realists and constructionist realists agree that the R-groups are constructed as real social groups by being viewed and treated as though they were relatively homogenous groups, differing in significant, inherent, heritable ways. Only, anti-realists insist they are not races, but racialized groups. I seek to harness their agreement about the socially constructed nature of the R-groups to break the impasse between anti-realists and constructionist realists and settle their dispute in the anti-realist position's favour. On the account of their social construction agreed by both sides, R-groups exhibit empty concept dependency: they depend for their existence on people's utilizing a concept with no referent. Race cannot be both the concept which captures the R-groups’ nature and the empty concept on whose utilization their existence depends. When we are forced to choose, I argue, the latter is the only justifiable option.

Vitamin K has important physiological functions which relate to blood coagulation (its classical role), bone health, inhibition of arterial calcification, as well as anti-inflammatory effects. National nutrition survey data have shown that over half of all adults in Ireland and the UK have low vitamin K1 intakes (£1 μg/kg body weight/d). Vitamin K biofortification of food may be an important complementary food-based approach for improving vitamin K intakes. Our study aimed to explore the feasibility of producing vitamin K-biofortified eggs via increasing the vitamin K3 content of the hen diet, and to examine any effects on hen performance and egg/eggshell quality parameters. A 12-week hen feeding trial was conducted in the Agri-Food and Biosciences Institute, Belfast, UK. Hyline chickens (n = 128) were randomized into 4 treatment (T) groups (n = 32 hens/group) and fed diets containing 3 (T1-industry standard), 12.9 (T2), 23.7 (T3) and 45.7 (T4) mg vitamin K3/kg of feed. Hens were provided feed ad libitum and feed intake was recorded weekly. Eggs were collected daily and weighed. While egg quality and vitamin K content was assessed at week 0, 4, 6, 8 and 12, the trial endpoint (week 12) data was prioritized for the current analysis. Total vitamin K content (i.e., vitamin K1 plus menaquinone (MK)-4 and MK-7) of composite samples (n = 12 eggs/treatment), measured using a novel, sensitive liquid chromatography-mass spectrometry method at Teagasc, increased from 22.4 μg/100 g (whole egg) in T1 (control and commercial level of vitamin K3) to 57.8 μg/100 g in T4. MK-4 was the most abundant form of vitamin K found in the eggs. Eggshell weight and eggshell thickness in T2 and T3 (but not T4) were significantly higher than in T1 (by 20–28%, P < 0.05). Likewise, based on colourimetric assessment, yellowness (parameter b*) of the egg yolk in all three biofortified groups was significantly higher compared to T1 (by 27–45%, P < 0.05). Haugh unit of the eggs and hen performance parameters, such as feed intake, feed conversion ratio and egg production, were unaffected by vitamin K-biofortification. In conclusion, increasing the level of addition of vitamin K3 to hen feed significantly increased the total vitamin K content of eggs, and without any evidence of negative effects on egg quality or hen performance. Consumption of an average sized (60 g) vitamin K-biofortified egg could contribute an additional 35 μg total vitamin K. The effects on eggshell parameters could be of importance in terms of revenue loss due to breakages.

The current study was aiming to report the prevalence of suboptimal vitamin D status among schoolchildren in Greece and investigate the role of sex, urbanisation and seasonality on vitamin D status. A sample of 2386 schoolchildren (9–13 years old) from four distinct prefectures was examined. The prevalence of 25-hydroxyvitamin D (25(OH)D) concentration <30 and <50 nmol/l (vitamin D deficiency and insufficiency respectively) was 5·2 and 52·5 %, respectively. Girls had a higher prevalence of 25(OH)D<30 (7·2 v. 3·2 %) and 50 nmol/l (57·0 v. 48·0 %) than boys (P<0·001). The highest prevalence rates of 25(OH)D<30 and 50 nmol/l (9·1 and 73·1 %, respectively) were observed during spring (April to June), whereas the lowest (1·5 and 31·9 %, respectively) during autumn (October to December). The prevalence of 25(OH)D<50 nmol/l was higher in urban/semi-urban than rural regions, particularly during spring months (74·6 v. 47·2 %; P<0·001). Female sex, urban/semi-urban region of residence and spring months were found to increase the likelihood of vitamin D deficiency and insufficiency, with the highest OR observed for spring months (7·47; 95 % CI 3·23, 17·3 and 5·14; 95 % CI 3·84, 6·89 for 25(OH)D<30 and 50 nmol/l respectively). In conclusion, despite the southerly latitude, the prevalence of low vitamin D status among primary schoolchildren in Greece is comparable to or exceeds the prevalence reported among children and adolescents on a European level. Sub-populations at highest risk are girls in urban/semi-urban areas during spring months, thus indicating the need for effective initiatives to support adequate vitamin D status in these population groups.

Summary
In 1967, all London medical schools were separate institutions based on their teaching hospitals, many of which had moved from their original central sites. Successive attempts at merger met resistance, but by 2000 there were just five undergraduate schools, all incorporated in large multi-faculty colleges with the exception of St George's.
IMPERIAL COLLEGE LONDON
In the north-west, Imperial College absorbed St Mary's Hospital in 1989 and in 1997 also took in Charing Cross and Westminster Hospitals (already merged in 1983).
Charing Cross Hospital
Early development of general practice teaching
Charing Cross Hospital medical school started in the mid-nineteenth century at the hospital building near The Strand, London. It was small, taking twenty to thirty new students annually. General practice teaching started in the 1950s when students were invited to stay with a general practitioner (usually an alumnus) for three weeks in their final year. Most practices were outside London (often rural), enabling students to experience the daily life of a general practitioner, including out of hours work and living with his family.
Charing Cross Hospital moved to Fulham in 1974, and the annual school intake increased to 120. The final-year general practice attachment expanded accordingly and the Dean, Professor Glenister, initiated plans for an undergraduate general practice teaching unit. The education committee of the north and west London faculty of the RCGP took great interest in the developments, especially as the GMC was threatening to remove accreditation from schools that did not have departments of general practice.

This paper reports the first experimental results in which the kinetic energy of cold fog, generated in a water arc plasma, exceeds the electrical energy supplied to form and maintain the arc. The cold fog explosion is produced by breaking down a small quantity of liquid water and passing a kiloampere current pulse through the plasma. The 90-year history of unusually strong water arc explosions is reviewed. Experimental observations leave little doubt that internal water energy is being liberated by the sudden electrodynamic conversion of about one-third of the water to dense fog. High-speed photography reveals that the fog expels itself from the water at supersonic velocities. The loss of intermolecular bond energy in the conversion from liquid to fog must be the source of the explosion energy.
