POSITIVE AND NEGATIVE ION MASS SPECTRA OF RING - SUBSTITUTED NITROBENZENES
The 70 ev positive and negative ion mass spectra of ring-substituted nitrobenzenes were studied. The influence of the substituent group on the fragmentation modes of the molecular ions is discussed. The effect of pressure in the formation of negative ions was also studied. As expected, the ratio of fragment ions to negative molecular ions decreased with increasing pressure in ion source.
متن کاملP113: Predicting Body Image Anxiety Based on Positive and Negative Perfectionism and Body Mass Index
Body image is an internal representation of the external appearance which includes physical and perceptual aspects and attitudes toward them. Body image anxiety can cause weight problems. In addition, perfectionism, the trend or effort to be perfect and flawless can cause extreme thinking and self-criticism. Perfectionism can provoke anxiety and concerns for body image and weight, especially in...
متن کاملMass drug administration, mass screening and treatment and focal screening and treatment for malaria
Mass drug administration (MDA) has received renewed interest over the past decade in the context of malaria elimination, as part of multidrug resistance containment and (more recently) in emergency situations such as the West African Ebola outbreak. To develop WHO recommendations, a group of experts met in April 2015 to review recent evidence on the use of MDA, mass screening and treatment (MSA...
متن کاملEnhanced expression of N-myc messenger RNA in neuroblastomas found by mass screening.
A substantial fraction of neuroblastomas found by mass screening have been suggested to regress spontaneously because of the high incidence of infantile neuroblastomas in the screening population. In this study, 70 neuroblastomas were analyzed for expression of proto-oncogenes related to neuronal differentiation to clarify the biological significance of proto-oncogene expression in the screenin...
متن کاملMass screening of the newborn for metabolic disease.
Over large parts of the world all newborn infants are, in principle or in practice, examined by some biochemical technique for phenylketonuria. This revolutionary practice is barely 10 years old; it is worth considering how it started and why it has spread. Until the development of a dietary treatment, phenylketonuria was considered, like the other inborn errors of metabolism, a suitable subjec...
