The relationships between height increment of Scots pine (PINUS SYLVESTRIS L.), birch (BETULA PUBESCENS Ehrh.) and rowan (SORBUS AUCUPARIA L.) during one growing season to meteorological variables at 580 m above sea level in the northern Pennines were previously examined using orthogonalized regression analysis. The paper describes methods made to improve the efficiency of the models. Values of principal components of the meteorological variables of the current and preceding sets were associated with 76.5, 60.4 and 75.9 percentage of variability respectively, showing an improvement by allowing for lag effects in this way. Efficiency of using values of the original variables, with those of the preceding set, or with curvilinear terms, was generally less. Variation of response during the season was examined and was discussed in terms of plant behaviour. [ABSTRACT FROM AUTHOR]

The biophotothermal time scale for barley derived previously and based on daily maximum and minimum temperatures and photoperiod was examined and tested further. The threshold temperature of 4.3°C and the optimum of 19 or 20°C found for the planting to emergence phase, and the optimum temperature values of 18.4°C for minimum and 24.8°C for maximum for heading to soft dough were not inconsistent with the results of other authors. For some of the other cardinal points, no meaningful values were found. Tests of the biophotothermal equations with independent data indicated that they could usefully be applied under the environmental conditions prevailing on most of Canada's present or potential farmland. They gave dubious results when applied to very cool marine climates on some exposed coastal parts of Canada, and were unsatisfactory for the short-day regimes that affected early-season plantings at Buenos Aires. The equations for barley seemed much less universally applicable than those for wheat. [ABSTRACT FROM AUTHOR]

Hot dry winds (Sharav) produce increased ionisation of the atmosphere, values for positive and negative ions going up from an average of 1, 000 per cm to 1, 500. There was almost always a slight preponderance of the positively-charged small ions. This increased air ionisation induces serotonin release in about one-quarter of the population with multiple complaints of a typical serotonin irritation syndrome. In 75% of 129 subjects suffering from serotonin ailments, the treatment with negative air ions (Ionotron) with an output of 3.5 × 10 ions/(cm · sec) at 1 m distance produced prophylactic and therapeutic relief when the patients were kept in a room of up to 4 × 4 m size. These results were controlled by serotonin and 5-HIAA urinalysis. [ABSTRACT FROM AUTHOR]

Exposure of 20 subjects to negative ionisation was monitored by EEG. Negative ionisation was supplied by an Ionotron apparatus (Amcor-Amron, Herzlia-Israel) with an output of 3.5 × 10 ions/(cm · sec) at 1 m distance. Objective findings in ten normal subjects showed reduction of the frequency of the alpha-waves from 10 or 11 down to 9 or 8 Hz, increase of the amplitude by up to 20%, advance of the alpha rhythm pattern from the occipital to the frontal area and general synchronisation of the EEG records of both hemispheres. These reactions were suppressed in 10 subjects by tranquillisers. Subjective findings included relaxation, alertness, improved working capacity and relief from the Serotonin Irritation Syndrome produced by the positive ionisation of hot, dry desert winds.

In 10 subjects susceptible to high altitude pulmonary oedema (HAPO) plasma cortisol and antidiuretic hormone (ADH) and urinary catecholamines were estimated both at sea level and daily during their stay at 3, 500 m (Leh). At high altitude 4 of the subjects developed HAPO, 2 got acute mountain sickness (AMS) and 4 remained unaffected. Plasma cortisol showed a sharp rise on the first day at high altitude in all the subjects. Thereafter, it declined gradually in the unaffected subjects. In the HAPO patients there was a sharp fall in the plasma cortisol level combined with antidiuresis. Changes in plasma ADH and urinary catecholamines were not consistent. It appears that failure in the normal adrenocortical response to altitude stress in susceptible subjects is a factor in precipitating HAPO. [ABSTRACT FROM AUTHOR]
