CHAPTER FOUR PROTACTINIUM Boris
Protactinium, element 91, is one of the most rare of the naturally occurring elements and may well be the most difficult of all to extract from natural sources. Protactinium is, formally, the third element of the actinide series and the first having a 5f electron. The superconducting properties of protactinium metal provide clear evidence that Pa is a true actinide element (Smith et al., 1979)....
متن کاملA New Class of Zero-Inflated Logarithmic Series Distribution
Through this paper we suggest an alternative form of the modified zero-inflated logarithmic series distribution of Kumar and Riyaz (Statistica, 2013) and study some of its important aspects. The method of maximum likelihood is employed for estimating the parameters of the distribution and certain test procedures are considered for testing the significance of the additional parameter of the model. ...

متن کاملHydroxychloroquine-induced Unusual Generalized Pustular Cutaneous Reaction As a New Clinical Entity: A Case Series
Background: Pustular Psoriasis (PP) and Acute Generalized Exanthematous Pustulosis (AGEP) clinically resemble each other. There are many patients with generalized pustular presentations like hydroxychloroquine-induced pustular reaction who do not completely fall within PP or AGEP categories and needed to be more evaluated. So we examined a large series of these reactions to hyd...
متن کاملRadioactive Materials in New Zealand Industry
Certain materials "decay" at the atomic level over a period of time, giving off "radiation" in the form of energy or subatomic particles. This radiation can be harnessed and used for a variety of industrial applications. Some of the commonest of these which are used in New Zealand are listed below, although many others exist that are either only used to a small extent or used exclusively overseas.
