Growth of the ultraviolet-irradiated cell is of special interest. Growthmay offer a simpler measure of radiation effect than survival. Growth after irradiation is a reflection of events in the latent or middle period between the irradiation and the end biological result (Kelner, 1954; Latarjet and Gray, 1954; Kelner et al., 1955; Barner and Cohen, 1956). During this period the ultraviolet damag...

Out of a total capital expenditure of Regional Hospital Boards on hospital services during the financial year 1954-55, a sum representing 30.2 per cent, was allocated to mental and mental deficiency hospitals (compared to 22 per cent, for the period 1948-55). The percentage allocated for this purpose by individual Regional Boards varied from 52 per cent. (Oxford) to 16.2 per cent. (Manchester)....

data envelopment analysis (dea) is a mathematical technique to evaluate the performance of firms with multiple inputs and outputs. in conventional dea models, the efficiency scores of decision making units (dmus) with non-negative inputs and outputs are evaluated in a special period of time. however, in the real world there are situations wherein performance of firms must be evaluated in multip...

The aim of this study was to describe bronchoscopic findings and the spectrum of pulmonary pathogens in HIV seropositive patients undergoing investigation of respiratory disease over a 10 year period in a major UK referral centre. METHODS Recruitment was procedure based with...

Background and Objective: Malignant otitis externa is a rare but potentially fatal infection. It tends to affect the elderly as well as patients with diabetes and immunocompromised status. We aimed to identify the epidemiological, clinical, therapeutic, and evolutionary features of malignant otitis externa. Methods: We conducted a retrospective study including patients hospitalized in the infe...

Several cross-sectional studies of children's body measurements have been made from which average growth may be inferred (Hammond, 1953a; Provis and Ellis, 1955; Clements and Pickett, 1955 and 1956 for school ages. Low, 1952; Acheson and Hewitt, 1954; Hammond, 1955; Thomson, 1956 for pre-school ages). But it is impossible to assess the significance of departures from average growth unless norma...

AIMS The decomposition of trends in alcohol volume and heavy drinking days into age, period, cohort and demographic effects offers an important perspective on the dynamics of change in alcohol use patterns in the United States. DESIGN The present study utilizes data from six National Alcohol Surveys conducted over the 26-year period between 1979 and 2005. Setting United States. MEASUREMENTS...

Annual needle production (PROD) of Scots pine (Pinus sylvestris L.) and pine pollen accumulation rates (PAR) are compared along a 5-site transect from the Arctic Circle to the northern timberline. PROD is calculated using the Needle Trace Method (NTM). PAR is monitored by two series of pollen traps, located in the centres of mires and within forests, respectively. There is a strong year-to-year...
