TL;DR: In the search for a way of speeding up the pendant drop method of measuring surface tension, a development was made which permitted a reduction of approximately 75 per cent in time required for a determination.
Abstract: In the search for a way of speeding up the pendant drop method of measuring surface tension, a development was made which permitted a reduction of approximately 75 per cent in time required for a determination. This modified method permits a monetary saving in addition to the saving in time, by eliminating a photographic process. This method offers advantages over other surface tension methods for certain uses.

TL;DR: An objective method of measurenient which would permit quantitative and qualitative measurements would be of great value, particularly if it permitted measurements below the threshold level of the human nose.
Abstract: The importance of an objective niethod of odor measurement is well recognized. Such a technique would eliminate physiological and psychological factors present, very prominently, in subjective test methods. An objective method of measurenient which would permit quantitative and qualitative measurements would be of great value, particularly if it permitted measurements below the threshold level of the human nose.

TL;DR: A preliminary in vitro study to determine the effect of alcohol vapor on the surface tension of water was carried out, which suggested a method for determining theeffect of deodorants on the elimination of alcohol breath.
Abstract: A preliminary in vitro study to determine the effect of alcohol vapor on the surface tension of water was carried out. A similar determination of the effect of alcohol breath was tried with positive results, which suggested a method for determining the effect of deodorants on the elimination of alcohol breath.

TL;DR: The effects of air contaminations caused by certain standard odorants on the surface tension of a liquid drop were determined with and without the presence of deodorants.
Abstract: The effects of air contaminations caused by certain standard odorants on the surface tension of a liquid drop were determined with and without the presence of deodorants. An attempt to develop a standardized statistically sound technique for measuring the effect of deodorants was made.

TL;DR: The effect of chlorophyllins on various odorants was studied using an improved surface tension method for the detection of odorant substances and it was found that certain odorants could be detected and measured by the technique while others could not and could not be studied by the method employed.

TL;DR: Pharmacy students indicated a strong desire to play a role in doping prevention and ensure safe and rational use of drugs among athletes and suggested requiring an education and training strategy for sports pharmacy in undergraduate pharmacy curricula.
Abstract: Objective. To assess pharmacy students’ knowledge and perceptions of doping and anti-doping in sports and to explore the curricular needs for undergraduate pharmacy in the field of sports pharmacy.
Methods. A cross-sectional, descriptive, web-based survey of pharmacy students was conducted at Qatar University College of Pharmacy from March to May 2014. Data were analyzed using descriptive and inferential statistics.
Results. Eighty respondents completed the online survey (80% response rate). Sixty percent were unaware of the World Anti-Doping Agency, and 85% were unaware of the International Pharmaceutical Federation’s statement on the pharmacist’s role in anti-doping. Students’ knowledge score regarding the prohibited status of drugs that may be used by athletes was around 50%. Fourth-year pharmacy students had significantly higher knowledge scores than the other groups of students. Respondents acknowledged the important role of health care professionals, including pharmacists, as advisors on the safe and effective use of drugs in sports. Ninety percent of the students supported the inclusion of sports pharmacy in the curriculum.
Conclusion. Pharmacy students indicated a strong desire to play a role in doping prevention and ensure safe and rational use of drugs among athletes. They suggested requiring an education and training strategy for sports pharmacy in undergraduate pharmacy curricula.

Abstract: used in the earlier publication. No doubt some errors exist in classification since i t was done on the basis of informat ion contained i n the titles and abstracts rarher than on the basis of examination of al l articles. W e believe rhe bibliography to be reasonably complete. Some articles have been omitted. In some instances this was intentional because examination of the article indicated its content to be quite disparate from the topic covered. In other instances items have been missed because the title or abstract was nor listed in rhe indexes of abstracting journals. W e have, however, cross-checked our list against the bibliographies and cited literature of a great many publications that we have studied as relevant to our own research.
