Abstract:
The existence of imaginary mass associated to the neutrino is already well-known. Although its imaginary mass is not physically observable, its square is. This amount is found experimentally to be negative. Recently, it was shown that quanta of imaginary mass exist associated to the electron and the photon too. These imaginary masses have unusual properties that violate the Parity Conservation Principle. The non-conservation of the parity is also found in the weak interactions, and possibly can be explained by means of the existence of the imaginary masses. Also protons and neutrons would have imaginary masses associated to them and, in this way, atoms and molecules would also have imaginary masses directly proportional to their atomic and molecular masses. The Parity Conservation Principle holds that the material particles are not able to distinguish their right from their left. The non-conservation of the parity would necessarily imply capability of "choice". Thus, as the particles with imaginary mass don't conserve the parity, they would have the elementary capability of “choosing between their right or left”. Where there is “choice” isn’t there also psychism, by definition? This fundamental discovery shows that, in some way, the consciousnesses are related to the imaginary masses. This fact, make it possible to redefine Psychology on a Quantum Physics basis.
The authors report the results of a six-month evaluation of otomycoses in the ENT Department of CHU and the Central Hospital of Yaoundé. We examined 2 592 patients of both sexes presenting with ear affections. The prevalence of Otomycoses is 6,09%. This is an adult problem with both sexes equally affected. Clinically the main symptoms were burning sensation in the ears, pruritus, sensation of fullness in the ear, hypoacousia and otorrhea. Clinical lesions are of many types including myringitis, tympanic perforation and otitis externa. The fung...
Records of 46 patients who were treated for primary hyperparathyroidism at King Khalid University Hospital, Riyadh Saudi Arabia from 1st July 2000 to 30th June 2006 were reviewed. Mean age at diagnosis was 44 years (range 13-70 years) and average duration of symptoms was 39 months (1 month to 11 years). There were 35 females and 11 males with a ratio of 3.2:1. Bone pains were the major symptoms at presentation in 45.7% followed by no symptom in 23.9%, renal stones in 15.2%, polyuria in 6.5%, while 4.3% each presented with depression, and consti...
The purpose of the study was to investigate to what extent the physical activity pattern in adulthood can be predicted by physical characteristics, performance and activity in adolescence. A group of 62 men and 43 women completed a questionnaire concerning physical activity during their leisure time at the ages of 16 and 27 years. An activity index produced from the questionnaire. At the age of 16 years, the subjects were also tested for strength (strength test battery) and running performance (9-min run). Maximal oxygen uptake (VO2max) was est...
The aim of the study was to investigate relationships between physical fitness and self-reported physical activity in adulthood and to what extent the level of physical fitness and leisure-time physical activity in adulthood can be explained by anthropometric measures, physical performance, physical activity, attitudes to sports activities and socio-demographic characteristics at the age of 16. A group of 157 men and 121 women was tested at the ages of 16 and 34 by means of questionnaires and fitness tests. Physically active men and women had h...
OBJECTIVE: To evaluate the effects of a comprehensive physical activity (PA) promotion programme in elementary schools on children's total PA levels, leisure-time PA, physical fitness and psychosocial correlates of PA. DESIGN: A pre-test-post-test design over two school years. SETTING AND SUBJECTS: Sixteen elementary schools (764 children, mean age: 11.2 +/- 0.7 years) were randomly assigned to the intervention condition (n = 8) and the control condition (n = 8). The intervention included a health-related physical education programme, an extrac...
Adjectives are supposed to describe the associated noun more fully or definitively, and the adjective physical is sometimes added to words such as medicine, rehabilitation and disability. What increase in description does its use allow? The adjective was probably added when rehabilitation started to develop for several reasons: it contrasted the mode of treatment with pharmacology and surgery; it contrasted the nature of the supposed aetiology with emotionally generated disorders, especially shell-shock; and it justified the presence of rehabil...
The Report of the Royal College of Physicians on Physical Disability in 1986 and Beyond gives details of a Medical Disability Service to redress the present imbalance in the provisions for the physically disabled. An integral part of this service should be the provision of adequate scientific and technical resources, which could be established by making four or five new Medical Physics and Clinical Engineering appointments annually in each Region for the next ten years.
INTRODUCTION: We examined predictors of 2 important health behaviors, namely, physical activity and nutritional behaviors, in a sample of community-living women with physical disabilities (N = 386). METHOD: We conducted a cross-sectional survey with regression analysis. RESULTS: Our regression model accounted for 33.5% of the variance in physical activity. Women with joint problems or multiple sclerosis tended to engage in less physical activity than those with stroke-related disabilities. Those who had lived with their disability longer and th...
AIM: Previous studies that examined participation in physical activity suggested that female adolescents were less active compared with males. However, the relationship between physical fitness, physical activity participation, and perceived benefits and barriers for physical activity to adolescents, irrespective of gender, has not been made clear. This study examines the association of these factors in female adolescents. METHODS: Physical activity participation and perceived benefits and barriers to physical activity were determined in 206 se...
We compared the effect of a group-based 12-week supervised exercise programme, i.e. aerobic and resistance exercise, and group sports, with that of the same programme combined with cognitive-behavioural training on physical fitness and activity of cancer survivors. One hundred and forty seven cancer survivors (all cancer types, medical treatment >or=3 months ago)were randomly assigned to physical training (PT, n=71) or PT plus cognitive-behavioural training (PT+CBT, n=76). Maximal aerobic capacity, muscle strength and physical activity were ass...
The purpose of this perspective is to present a general theory--the Physical Stress Theory (PST). The basic premise of the PST is that changes in the relative level of physical stress cause a predictable adaptive response in all biological tissue. Specific thresholds define the upper and lower stress levels for each characteristic tissue response. Qualitatively, the 5 tissue responses to physical stress are decreased stress tolerance (eg, atrophy), maintenance, increased stress tolerance (eg, hypertrophy), injury, and death. Fundamental princip...
OBJECTIVES: To examine the hypothesis that changes in self-efficacy and functional performance mediate, in part, the beneficial effect of physical activity on functional limitations over time. DESIGN: Prospective, observational study. SETTING: Community-based. PARTICIPANTS: Two hundred forty-nine community-dwelling older women. MEASUREMENTS: Participants completed measures of self-reported physical activity, functional limitations, and self-efficacy. Four measures of physical function performance were also assessed. Measures were completed at b...
Fifty-five men and 28 women were tested at age 16 and retested at age 27. Muscle biopsies were taken from m. vastus lateralis to analyse fibre types, fibre areas and enzyme contents. A cycle ergometer test to was used to estimate the maximal oxygen uptake. Physical performance was assessed in an endurance test, where the subjects had to run as far as possible in 9 min on a 400-m track, and in three strength tests designed to test maximal dynamic strength (Sargent jump) and maximal static strength (handgrip test, two-hand lift). The subjects ans...
