The main constituents of fatty acid was hexadecanoic acid (34.42%), 9,12,15- octadecatrienoic acid (10.39%), octadecadienoic acid (7.63%) and 7,10,13- hexadecatrienoic acid (5.60%).
A total of 52 compounds have been identified in the fresh China wingnut(Pterocarya stenoptera C.DC) extracted by SPME and GC-MS. The principal components are nerolidol(15.54%),germacrene A(14.22%),trans-caryophyllene(10.19%),7,8,9,10-tetrahydro-S-diazole(3,4-A)-phthalazine(8.59%)and hexadecanoic acid(6.22%).
The main fatty acid is hexadecanoic acid with relative content of 34.4%. The polyunsaturated fatty acids (PUFA) covered 32.7% of total fatty acids. The main constituents of PUFA were C_(16), C_(18), C_(20) unsaturated fatty acids.
By way of direct calculation, a sixteen dimension representation space was reducted in terms of group S_4 and group SU_2. This space was obtained by four direct products of the foundation representation space of group SU_2. The basic fundations of the irreducible represen- tation of group S_4 and group SU_2 were figured out.
The experimentally observed values of effectiveness factors obtained therefrom under sixteen conditions are from 0.142 to 0.455, and the relative errors of model prediction values with respect to experimentally observed values under the same reaction conditions are in the range of -0.25 to 0.06. The results of comparison are satisfactory.
Self-construct questionnaire、 16PF (Cattell the Sixteen Personality Factor Questionnaire) , SCL—90 (Symptom Checklist 90) and CIEF—5 (Chinese Index of Erectile Function 5) were applied by mail, phone call and interview.
It is likely that these 24 terms are from the two Dialects which were written by LiuBing and WangHao respectively in the period of the Sixteen States(十六国) andsometime later.
3-Hydroxydecanoic, 2-hydroxydodecanoic, 3-hydroxydodecanoic, dodecanoic, hexadecanoic, octadecanoic, hexadecenoic, and octadecenoic fatty acids were present in lipid A of the LPS of all the strains studied.
The main components of the lipid A hydrophobic moiety were 3-hydoxydecanoic, 2-hydroxydodecanoic, 3-hydroxydodecanoic, dodecanoic, and hexadecanoic fatty acids.
1. All kinds of colonies of Volvox africanus were found in great abundance during the first two weeks of May, 1933, from a pond in Nanking.2. The smallest colony is much smaller than that recorded from Africa and the Philippine Islands.3. The somatic cells are not connected by protoplasmic filaments in adult colonies.4. Asexual colony usually contains from two to six daughters symmetrically arranged in pairs according to size on opposite sides of the polar axis.5. Sexual colonies of different kinds are deve...
An analysis of the existing data for doubly ionized calcium in the extreme Schumann region below 1010 was made, and practically all the bright lines in this region were classified. 16 new terms were tabulated. The isoelectronic sequence A I. K II. and Ca III was dismissed. An interesting new level 3s3p +s3S1, which combines with all the Ss23p5+s terms, is obtained in the analysis.
The present paper gives a report on the observations of the citrus psylla, Diaphorina citri Kuwayama, found in Focchow and Changchow of Fukien Province. The insect has been reported as an important citrus pest in south-eastern Asia, and is heretofore recorded from Kwangtung by Hoffmann (1936) and from Taiwan by Shiraki (1934). The citrus psylla attacks l3 species of plants of the family Rutaceae. Eggs are laid on the leaves of the young growth. The feeding of both the nymphs and adults on foliage of the ne...
