The description of underwater soundscape is central to the understanding of the marine environment, both from the standpoint of the fauna and anthropic activities and its interactions with the atmosphere. Some of these sources produce signals whose patterns are periodically repeated over time (i.e.

A survey of alcohol drinking habits using a questionnaire was conducted in a practice with 2 GPs and 4500 patients. Six hundred and thirty-two questionnaires were completed by all patients aged 15 and over attending the surgery during a three month period. Forty-five patients drinking in excess of 20 units of alcohol per week were identified, 22 of whom submitted to formal interview, examination, haematology, serum biochemistry and an education plan.

Estimated doses of 10 sporozoites were given to four patients, of 100 to three patients, of 1,000 to two patients, and of 10,000 to two patients. Parasitaemia was detected in all patients 12 to 17 days after inoculation; fever began on the 14th to 19th days.

It was clearly demonstrated by quantitative observations that the phenomenon may be elicited by the inoculation of small numbers of sporozoites. After the intradermal inoculation of 10 or 100 sporozoites, the incubation period was delayed for periods varying between 262 and 628 days; after u,000 sporozoites, with one exception, the same delay occurred; after 100,000 sporozoites, the incubation period was always of normal duration (13--16 days).

In order to contribute to knowledge of the sporogonic cycle of malaria parasites, 3 batches of Anopheles labranchiae atroparvus were infected with the VS Romanian strain of Plasmodium malariae by feeding them on 2 patients undergoing malariotherapy in Romania. Of the 310 infected mosquitos 59 were dissected for ookinetes, oocysts and sporozoites, and the rest were used for further clinical trials in England. Mature ookinetes were observed 18 hours after infection, and sporozoites were first observed in the salivary glands 19 days after infection.
