Reaction Types

Stage fright in singers: three reaction types.

Drawing on both my own personal experience and that of many colleagues and pupils, I shall describe three kinds of reactions to stage fright. The first is the primarily mental reaction of derealization, which involves feeling cut off from fear and decreasing body awareness. The second and third reactions to stage fright involve (a) increased and (b) decreased muscle tonus and their associated b...

Polymerase Chain Reaction: Types, Utilities and Limitations

Discriminating the reaction types of plant type III polyketide synthases

Motivation Functional prediction of paralogs is challenging in bioinformatics because of rapid functional diversification after gene duplication events combined with parallel acquisitions of similar functions by different paralogs. Plant type III polyketide synthases (PKSs), producing various secondary metabolites, represent a paralogous family that has undergone gene duplication and functional...

Formation of Two Types of Alumina/Intermetallic Composites based on the Reaction of Ilmenite and Aluminum

Ilmenite is a valuable industrial mineral containing Fe and Ti elements. Two composites with different morphology and composition were produced using the reaction of synthesized ilmenite and aluminum. The molar ratios of 1:2 and 1:8 were selected. The critical temperatures of each molar ratio were determined using the Differential Thermal Analysis (DTA). The heat treatment of the systems ...

Polymerase Chain Reaction Study of Anogenital Condylomas for High Risk HPV Types

Background: Anogenital wart is a common sexually transmitted disease affecting both genders. The aim of this study was to evaluate human papilloma virus types of anogenital warts with Polymerase Chain Reaction (PCR). Method: 65 formalin fixed paraffin embedded (FFPE) tissue blocks of the anogenital warts obtained from the pathology lab of Loghman Hakim hospital were included in this study. Resu...
