Rapid Surface Tension Determinations Using a Modified Pendant Drop Technique

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.

Study of odors.

Abstract: Odors have been difficult to measure and classify with accuracy principally because no objective measuring method has been developed. The mechanism of olfaction is but little understood; several theories have been presented but none has been generally accepted. This paper describes experiments in which an attempt has been made to detect contamination of the air at concentration recognized by the nose as strong odors. Studies have been made on the change of surface tension of a liquid drop due to air contamination resulting from nearby solid odorous material. The experiments described herein indicate that the surface tension of distilled water, mineral oil, and water-stabilized mercury may undergo considerable change when the air in contact with the drop is contaminated. The change of surface tension of a particular liquid follows a pattern characteristic of the contaminant. The same contaminant produces different surface tension changes in the three different liquids studied. The results of these tests suggest that an instrument might be developed which would be capable of classifying and measuring air contamination at low concentrations.

Surface phenomena related to odor measurements.

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.

A Proposed Method for Determining the Effect 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.

A Study in the Measurements of Odors and the Deodorizing Effects of Certain Materials

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.

The Design of an Artificial Olfactory System

Abstract: The aim of our research is to design an instrument which will mimic the human sense of smell. This ambition distinguishes our approach from that used in the related area of gas sensing. In the latter area, the object is usually to detect a single gas or vapour (frequently a toxic material) which has exceeded some predetermined threshold value. We use our sense of smell not only for detecting noxious vapours but also in a much more sophisticated way for classifying and grading smells.

The sense of smell in man--its physiologic basis.

Abstract: THE sense of smell has received scant attention in contrast to other special senses. Although it may be crucial to survival in animals, it seems less critical for man. Lack of knowledge stems, in p...

Knowledge and Perceptions of Pharmacy Students in Qatar on Anti-Doping in Sports and on Sports Pharmacy in Undergraduate 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.
