Let Pw and PM be the countable distributive lattices of Muchnik and Medvedev degrees of non-empty Π1 subsets of 2 , under Muchnik and Medvedev reducibility, respectively. We show that all countable distributive lattices are lattice-embeddable below any non-zero element of Pw. We show that many countable distributive lattices are lattice-embeddable below any non-zero element of PM .
1. Mackerel egg development was followed to hatching at constant temperatures of 10 degrees , 11 degrees , 12 degrees , 13 degrees , 14 degrees , 15 degrees , 16 degrees , 17 degrees , 18 degrees , 19 degrees , 20 degrees , 21 degrees , 22 degrees , and 24 degrees C. Experiment showed that typical development could be realized only between 11 degrees and 21 degrees . 2. The length of the develo...
this study was an attempt to investigate the effect of subtitling on vocabulary learning among iranian intermediate students. to find the homogeneity of the groups, tofel test was administered to student in kish mehr institute in garmsar. after analyzing the data, 60 participants (female students) who scored within the range of one standard deviation above and below the mean, were selected as h...
Several studies have suggested an association between ambient air temperature and blood pressure. However, this has not been reliably confirmed by longitudinal studies. Also, whether the reaction to temperature stimulation is modified by other factors such as antihypertensive medication is rarely investigated. The present study explores the relationship between ambient temperature and blood pre...
be influenced by several genetic factors.6 'The higher rate in the males might be accounted for by the assumption that the male sex stimulates the instability. Experiments are now in progress which are expected to throw more light on this problem. Summary.-Miniature-3 gamma gene is unstable in somatic cells. The results of experiments in which the flies carrying this gene were reared at 30 = 0....
BACKGROUND AND OBJECTIVES Explanations for laparoscopic-induced hypothermia fail to explain clinical observations. It is possible that water evaporation occurs from the jet stream of gas inflation resulting in tissue surface super-cooling leading to tissue damage and drying. METHODS Theoretical calculations based on thermal conductivity, mass transfer effects and heat flux considerations corr...
1. Whitefish eggs incubated in aerated lake water at controlled tempera tures of 0 degrees , 0.5 degrees , 2 degrees , 4 degrees , 6 degrees , 8 degrees , 10 degrees , and 12 degrees C., failed to hatch at either 0 degrees or 12 degrees C. 0.6 per cent hatched alive at 10 degrees C., 72.67 per cent hatched alive at 0.5 degrees C., and an intermediate proportion hatched at intermediate temperatu...
