    Polymorphism: an evaluation of the potential risk to the quality of drug products from the Farmácia Popular Rede Própria

    Polymorphism in solids is a common phenomenon in drugs, which can lead to compromised quality due to changes in their physicochemical properties, particularly solubility, and, therefore, reduce bioavailability. Herein, a bibliographic survey was performed based on key issues and studies related to polymorphism in active pharmaceutical ingredient (APIs) present in medications from the Farmácia Popular Rede Própria. Polymorphism must be controlled to prevent possible ineffective therapy and/or improper dosage. Few mandatory tests for the identification and control of polymorphism in medications are currently available, which can result in serious public health concerns

    Anders K. Angstrom was known primarily for his contributions to the field of atmospheric radiation. However, his scientific interests encompassed many diverse topics. This paper describes the contents of two early, remarkable, and, until recently, largely unknown papers by Angstrom on probability forecasting and the use/value of weather forecasts. These papers, entitled ''Sannolikhet och Praktisk Vaderleksprognos'' (''Probability and Practical Weather Forecasting'') and ''On the Effectivity of Weather Warnings, ''were published in 1919 and 1922, respectively. Noteworthy features of these two papers include 1) a discussion of the sources of uncertainty in weather forecasting, 2) discourses on the problems of estimating probabilities by means of empirical relative frequencies and forecasters' subjective judgments, 3) the use of a Gaussian model to describe the accuracy of minimum temperature forecasts, 4) the identification of the ratio of the protection costa to the ''risked value'' if protective action is not taken b as a characteristic of users of forecasts, 5) analytical expressions for the economic value of weather warnings, 6) quantitative analysis of the problems faced by forecasters in deciding whether or not to issue weather warnings when they are uncertain about future weather conditions, and 7) arguments concerning the need to obtain estimates of the costs and losses that may be incurred by potential users in order to assess economic effectiveness. The contents of Angstrom's two papers are reviewed and summarized, making extensive use of quotations from the texts. An effort is made to place the papers and their contents in proper historical context. Two topics of current interest, namely, ensemble forecasting and the provision of specialized weather services, are discussed briefly in light of the results presented and issues raised in these papers

    The Current State of Women Print Journalists: An Analysis of the Status and Careers of Females in Newspapers Sports Departments

    The purpose of this study was to provide an analysis of the current state of women journalists within the sports departments at newspapers across the United States. This investigation involved a determination of their demographic make-up, job status within the sports department, rationale for entering the field, and advice for younger women preparing to follow in their footsteps. The findings suggest that although the large majority of women have faced discrimination in the sport media, they believe improvements have been made towards equity. The majority of respondents noted that they were happy with the assignments they had been given. Subjects did, however, feel that they were assigned to cover females more than their male counterparts, and some responses regarding dissatisfaction with their positions was also noted.
