Since a Lie superalgebra can be associated with a Z 2 graded group, properties of Z 2 graded groups are discussed and Z 2 graded structures of some special classes of groups are determined.

(2 ) There were no significantly difference among serum levels of E2 in each graded group,indicated that the effect of prednisone for hemangiomas does not relate to the serum levels of E2. The serum levels of E2 can not be applied to prejuge the effect.

The problem addressed in this paper is the explicit computation of the graded group gr*N(Mn).

KWC was also higher for the middle graded group (152.8 kg) than for the low or (104 kg) or the high graded GG (118 kg) (p >amp;lt; 0.05).

Schr?dinger Q-representation of this graded group is obtained over the graded commutative algebra of 'doubly' complex numbers having two imaginary units with different parity.

This result is generalized here, by proving that every locally graded group with finitely many derived subgroups of non-normal subgroups has finite derived subgroup.

Moreover, a locally graded group is abelian by ?ernikov if and only if every proper subgroup is abelian by ?ernikov.

The important human's biorhythm composed of physical rhythm(23 cyclic days),emotional rhythm(28 cyclic days)and intellectual rhythm (33 cyclic days)is known as PEI cycle theory.It is the principal factor that has an effect on human behaviour.We made a deep investigation and study of the biorhythms of 300 students during the college entrance examination and made an attempt to study the practical application of biorhythms to examination. 55.35 percent of the students felt the biorhythms were present.The students...

The important human's biorhythm composed of physical rhythm(23 cyclic days),emotional rhythm(28 cyclic days)and intellectual rhythm (33 cyclic days)is known as PEI cycle theory.It is the principal factor that has an effect on human behaviour.We made a deep investigation and study of the biorhythms of 300 students during the college entrance examination and made an attempt to study the practical application of biorhythms to examination. 55.35 percent of the students felt the biorhythms were present.The students whose physical rhythms in positive phase(high tide)or negative phase(low tide)were respectively 41.33% and 42.0%(Pt>0.05),in cross phase(phase transition)was 16.67%.The students whose emotional rhythms in positive or negative phase were respectively 45.33% and 43.33%(Pt>0.05),in cross phase was 11.33%.This two rhythm phases have little effect on the result of examination based on the students' self -estimate. The students whose intellectual rhythms were in positive, negative or cross phases were respectively 45.33%,44.33% and 10.33%.The excellet self-estimate students in intellectual positive phases are superior to those in the low grade group(Pt<0.01).There are a close relation between the result of examination and intellectual rhythm phase.We know the result of examination is affected by multiple factors,therefore we must not have art exaggerate estimate of the result of examination based on biorhythm phases.

133 normal children and 113 deaf-mutes in Kindergarten, primary schooland deaf-mute school were asked to write Arabic numerals 1--10 and eightChinese words with eight writing patterns. The result reveals that firstgrade deaf-mute school childen wrote less mirror-words than normal Kin-dergarten children, but in the other compared grade groups there were nosignificant differances. In the age group of 8--10 the deaf-mutes wrotemore mirror-words than normal children, but in the other compared agegroups...

In the age group of 8--10 the deaf-mutes wrotemore mirror-words than normal children, but in the other compared agegroups there were no significant dtfferances. Through analysis we proposetwo key periods of the development of mlrror-writing: 1. development ofthe regulation and control of the brain of 5--6 year olds, 2.first two yearsof education due to the development of writing-skill.

Reoular examination shouldbe made to detect early esophageal cancer.
