The work on liver lecithins by Levene and Ingvaldsen’ and by Levene and Simms,z has shown the existence of lecithins which are distinguished from one another by the nature of their unsaturated fatty acids. There were isolated from liver lecithin, two unsaturated fatty acids, oleic and arachidonic, as well as two saturated acids, palmitic and stearic. Hence on the basis of the present findings i...

The use of dental hand pieces endanger dentists to vibration exposure as they are subjected very high amplitude and frequency. This paper has envisaged a comparative analysis amplitudes transmissibility during idling drilling with micro motor (MM) air-turbine (AT) pieces. study aims identify the mean difference in idling, explore different grasp forces while irrigant injection by dentist, vario...

The attitude of policymakers and designers of green space is increasing toward to native-ornamental species to plant in the urban space because of their adaptation and resistance against severe weather and ecological conditions which can result in cost minimization and long-term survival in green spaces. Hence, the current study was carried out in the west of Mazandaran Province on three wild a...

For the Levene model with soft selection in two demes, the maintenance of polymorphism at two diallelic loci is studied. Selection is nonepistatic and dominance is intermediate. Thus, there is directional selection in every deme and at every locus. We assume that selection is in opposite directions in the two demes because otherwise no polymorphism is possible. If at one locus there is no domin...

Evolution and the maintenance of polymorphism under the multilocus Levene model with soft selection are studied. The number of loci and alleles, the number of demes, the linkage map, and the degree of dominance are arbitrary, but epistasis is absent or weak. We prove that, without epistasis and under mild, generic conditions, every trajectory converges to a stationary point in linkage equilibri...

Codd tables are databases that can carry Codd’s null “value unknown at present” in columns that are specified as NULL. Under Levene and Loizou’s possible world semantics we investigate the combined class of uniqueness constraints and functional dependencies over Codd tables. We characterize the implication problem of this class axiomatically, logically and algorithmically. Since the interaction...
