In this study the cryo-unit is introduced as a new and useful instrument to investigate water-containing specimens with the SEM. Often water-containing biological specimens are studied, but in our case we used water-swollen polymer membranes. The results show that application of a cryo-unit permits the study of this material at low temperatures up to magnifications of about 10 000 times, while ...

We have analysed near-infrared NTT/SofI observations of the starburst cluster Westerlund 1, which is among the most massive young clusters in the Milky Way. A comparison of colour-magnitude diagrams with theoretical main-sequence and pre-main sequence evolutionary tracks yields improved extinction and distance estimates of AKs = 1.13 ± 0.03 mag and d = 3.55 ± 0.17 kpc (DM = 12.75 ± 0.10 mag). T...

The aim of the study was to analyse the variability of the leukocyte population and lymphocyte subpopulation in peripheral blood in ewes of different age and mammary gland health status and with different genotype in DBR1 (MHC II) gene. Blood samples were collected 3 times from 24 ewes of Polish Heath Sheep at the age of 6, 12 and 24 months. Milk samples were collected from ewes at the age of 2...

BACKGROUND The availability of reliable and comprehensive information on the health workforce is crucial for workforce planning. In India, routine information sources on the health workforce are incomplete and unreliable. This paper addresses this issue and provides a comprehensive picture of India's health workforce. METHODS Data from the 68th round (July 2011 to June 2012) of the National S...

Background: London accounts for nearly half of the national burden of tuberculosis. The incidence of tuberculosis has more than doubled in London in the past 15 years. Methods: Data from the enhanced tuberculosis surveillance 1999–2003, the national tuberculosis surveys of 1993 and 1998, and tuberculosis notifications were compared and analysed. Results: In 2003, 3048 patients with tuberculosis...
