Intended or Unintended Doping? A Review of the Presence of Doping Substances in Dietary Supplements Used in Sports
2017
Introduction: The use of dietary supplements is increasing among athletes, year after year. Related to the high rates of use, unintentional doping occurs. Unintentional doping refers to positive anti-doping tests due to the use of any supplement containing unlisted substances banned by anti-doping regulations and organizations, such as the World Anti-Doping Agency (WADA). The objective of this review is to summarize the presence of unlabeled doping substances in dietary supplements that are used in sports. Methodology: A review of substances/metabolites/markers banned by WADA in ergonutritional supplements was completed using PubMed. The inclusion criteria were studies published up until Se…
La gastronomía bien templada. La cocina quechua
2005
Un acercamiento al léxico sobre cocina en lengua quechua nos podría proporcionar algunas claves sobre su importancia en tiempos del imperio inca y sobre la que tiene, en el momento presente, la cocina patrimonial del Perú . No hace mucho un hablante de quechua nos decía convencido : " Piru llaqta wayk'uyninqa sumaqnin" (" la cocina de Perú es realmente exquisita").
Las lenguas como patrimonio : el principio de prioridad
2000
El primer paso en todo aquello que comprende el ámbito patrimonial es el reconocimiento de la herencia recibida. Luego hay otros: su conservación y ampliación y finalmente su transmisión a los descendientes.Todo esto ha sucedido con el quechua y el aimara en Perú, como si la lengua fuera ajena a los bienes nacionales. Es tan sagrada una piedra de Machu Picchu como una palabra de estas lenguas: tan importante es el lntiwatana, anteayer descubierto y hoy lacerado, como el significado de sus dos lexemas juntos lnti "sol", watay "atar, calcular su recorrido".

Spectroscopic and Structural Investigation of the Confinement of D and L Dimethyl Tartrate in Lecithin Reverse Micelles
2009
The confinement of D and L dimethyl tartrate in lecithin reverse micelles dispersed in cyclohexane has been investigated by FT-IR, polarimetry, electronic and vibrational circular dichroism (ECD and VCD), 1H NMR, and small-angle X-ray scattering (SAXS). Measurements have been performed at room temperature as a function of the solubilizate-to-surfactant molar ratio (R) at fixed lecithin concentration. The analysis of experimental data indicates that the dimethyl tartrate molecules are solubilized within reverse micelles in proximity to the surfactant head groups in the same way for the D and L forms. The encapsulation of dimethyl tatrate within lecithin reverse micelles involves changes in i…
An eco-label for the airline industry : instrument for behavioral change?
2017
Climate change is the biggest challenge humanity has ever faced and there is no doubt that human activities are the main cause. One activity that has received much attention in this discussion is air transportation. Although its contribution is still moderate, this industry is growing at a very fast rate and with that its impact on climate change. In order to enjoy its social and economic benefits also in the future and to avoid regulatory restrictions, the industry’s contribution needs to be kept in check. Various mitigation strategies exist such as technological, market-based, operational, regulatory and behavioral changes. This dissertation focuses on behavioral change. One instrument le…
The use of calcined paper mill sludge as a chemical precipitant in the simultaneous removal of ammonium and phosphate : paper mill waste recycling an…
2020
Currently, recycling and re-use of materials is extremely important due to the diminishing of natural resources. The objective of the European Union’s circular economy strategy is to increase recycling and the use of industrial waste materials and side streams as secondary raw materials. In this study, a chemical precipitation method to simultaneously remove ammonium nitrogen and phosphate from the liquid phase of anaerobic digestate using calcined paper mill sludge was studied. Papermill sludge is a waste material that forms in the paper-making process. In addition, commercial calcium oxide (CaO) was used as a reference precipitant. The suitability of the formed precipitate’s composition f…
The Design Towards a Collaborative Subscription Service : The Case of The Finnish Newspaper Industry
2020
The newspaper industry is challenged with its business models. To stabilize revenues, publishers opted for digital subscriptions for generating additional revenue streams. However, digital subscriptions showcase limited success. News aggregator platforms may promise publishers a pool of paying readers. But platform fees and the loss of customer relationships enact barriers among publishers to join. This study proposes a software prototype based on design science research to address the aforementioned shortcomings by deriving design principles for a collaborative subscription service. Building on the strategic alliance, digital platform and business model literature, this research aims to id…
The Design Towards a News Aggregator Subscription Service: Results from An Online Experiment
2021
The newspaper industry is on a quest to discover sustainable business models. Digital subscriptions are stable revenue generators for most publishers. That being said, smaller publishers face challenges. By not having the same resource base to offset costs compared to larger ones, small publishers are in a constant state of financial unpredictability. Another persistent problem among them is the high churn rate of subscriptions (i.e., the cancelation rate), which suggests a value misalignment between readers and service. New services like news aggregators may promise publishers a large pool of paying readers, as readers have access to diverse content by different publishers and are willing …
