Cliff and Lorimer (1) have proposed a simple approach to thin foil x-ray analy sis based on the ratio of x-ray peak intensities. However, there are several experimental pitfalls which must be recognized in obtaining the desired x-ray intensities. Undesirable x-ray induced fluorescence of the specimen can result from various mechanisms and leads to x-ray intensities not characteristic of electron excitation and further results in incorrect intensity ratios.In measuring the x-ray intensity ratio for NiAl as a function of foil thickness, Zaluzec and Fraser (2) found the ratio was not constant for thicknesses where absorption could be neglected. They demonstrated that this effect originated from x-ray induced fluorescence by blocking the beam with lead foil. The primary x-rays arise in the illumination system and result in varying intensity ratios and a finite x-ray spectrum even when the specimen is not intercepting the electron beam, an ‘in-hole’ spectrum. We have developed a second technique for detecting x-ray induced fluorescence based on the magnitude of the ‘in-hole’ spectrum with different filament emission currents and condenser apertures.

BACKGROUND YouTube is a popular American video-sharing platform that has been accessible to the public since 2005. Previous studies have shown that YouTube is potentially beneficial to medical education, but the quality of videos still need to be determined. OBJECTIVE The goal of this study is to understand the quality of the YouTube videos by evaluating the characteristics of physicians and the total number of views on videos regarding fibromyalgia. METHODS The term “fibromyalgia” was searched on the YouTube search engine by relevance, the default setting. Information from the first 100 videos were analyzed. A search was performed on Scopus to determine the h-index and fibromyalgia-related publication for any physician who was featured in the videos. RESULTS Of the top 100 videos, there were 64 academic videos, 18 vlogs, 5 interview videos, and 13 miscellaneous videos. Out of the 64 academic videos, 30 physicians, 7 Doctors of Philosophy (Ph.D.), 5 physical therapists, and 5 chiropractors were identified. The majority physicians have an adequate academic affiliation such as h-index and academic publications. CONCLUSIONS Residents and medical students will encounter a large number of academic videos on fibromyalgia on YouTube. This study suggests that many videos were posted for academic purposes and that the quality of the videos can be ensured to some degree. However, developing a better systemic evaluation of the quality of YouTube content is still necessary.

The main objective of this paper is to identify the platforms and social media tools utilized by the brewing industry in communication with the stakeholders, mainly with potential clients. In addition, the study sought to determine the nature of the published content, identify those responsible for their management, and present the advantages and disadvantages of their conduct in communication and creating the image of the company. The results indicate that only 25% of the surveyed companies do not use social media in PR. This applies only to small enterprises, with regional character. All the major brewing companies in their public relations activities use at least one type of social media, focusing in most cases on social networking (Facebook) and Video Sharing (YouTube). In addition, some of the largest brands included in the individual equity groups have their own social media channels used to communicate with the stakeholders. General promotion of company products and, what is very important, creating a dialogue with social media platform community, were seen as the most important benefits of using social media.
