We discuss some errors in The Feynman Lectures on Physics related to the concept of symmetry. We also suggest a possible correction to Fig.1.4 of Vol. I. The discussion may be useful for students of crystallography, solid state physics and solid state chemistry.  相似文献

Defects in biotin metabolism are mainly associated with either the enzyme Biotinidase or Holocarboxylase synthetase. Defects in either enzymes depletes biotin utilization by the cells. Holocarboxylase synthetase deficiency is an inherited disorder in which the body is unable to use the vitamin biotin effectively. This condition is inherited in an autosomal recessive pattern. We present a case of a 9 year old girl with atypical symptomology as a case holocarboxylase synthetase deficiency, who demonstrated an increased excretion of propionic and methyl malonic acids, with her biotinidase activity being normal. She demonstrated remarkable improvement on biotin supplementation.  相似文献

ABSTRACT

This article explores the concept of service branding in the context of libraries and information organizations. We discuss community perceptions of library brand value from the librarian's perspectives in the context of public and academic libraries. Librarians’ thoughts and viewpoints in improving the community's library experience are also discussed. The findings highlight the importance of improving the library's visibility, creating appealing ambience, and developing a strategic branding plan in order to provide robust, compelling, and meaningful experiences for their community.  相似文献

Genitourinary tuberculosis is a disease of the genitourinary system which includes the entire urinary tract and reproductive system. Genital tuberculosis is an important cause of female infertility, especially in developing nations like India. In the present study, a total of 257 clinical specimens comprising of endometrial biopsy (109), endometrial curetting (42), menstrual blood (8), semen (17), placenta (11) and urine (70) were collected from patients and subjected for PCR, Culture and AFB detection. The endometrial biopsy, endometrial curetting, menstrual blood, semen, placenta, urine showed 30.2, 45.2,12.5, 5.8, 27.2, 31.4 %, positivity rate for tuberculosis by PCR, 7.3, 9.5, 25.0, 0, 9, 8.5 % by culture and 1.8, 2.3, 0, 0, 0, 2.8 % respectively by AFB smear. Being a novel, rapid technique, PCR is the method of choice for rapid diagnosis and management of genitourinary tuberculosis shared with the other concerned tests. This study reveals that genital tuberculosis can occur in any age group, however, the majority of patients were from reproductive age (nearly 75 % of them were from 20–45 years of age) group.  相似文献
