["Influence of epidermal friction and wear on papillary patterns": unpublished fingerprinting experiments by Federico Olóriz Aguilera (1855-1912)]. / "Influencia del roce y desgaste epidérmico en el dibujo papilar": experiencias inéditas sobre dactiloscopia de Federico Olóriz Aguilera (1855-1912).

Federico Olóriz introduced in Spain a method of identification based on fingerprints that is now used in various other countries. Among the numerous studies he performed for this purpose is a hitherto unpublished experiment reported in this paper. The objective was to test whether fleshy parts of fingers that undergo manipulation can maintain their dermal folds in a manner that permits their correct identification. Olóriz found that dermal folds produced by a simple ligation did not pose serious identification problems, while alterations resulting from sharp elements generated greater but in some way surmountable difficulties. A brief biography of Olóriz is first provided, with a summary of his studies on Anthropology and, in greater detail, his dedication to Forensic Anthropology, which led to the development of the so-called "Olóriz Method" of identification by means of fingerprints.

Federico Olóriz fue el introductor en España de un método de identificación por medio de las huellas dactilares, actualmente en vigor en diversos países. Para ello realizó numerosos trabajos, entre otros, la experiencia, hasta ahora inédita, que presentamos. Olóriz se propuso comprobar si los pulpejos de los dedos sometidos a manipulación mantenían los pliegues dérmicos de forma que pudieran seguir sirviendo para la correcta identificación. En caso de un simple lijado, comprobó que los pliegues dérmicos no representaban problemas graves de identificación. En caso de alterarse con elementos punzantes, las dificultades eran algo mayores, pero en modo alguno insalvables. Previamente se ofrece una breve biografía del personaje y un resumen de sus estudios sobre antropología y, de forma más amplia, su dedicación a la antropología forense, que le llevó a poner en marcha el denominado «Método Olóriz» de identificación por medio de las huellas dactilares (AU)

A blended learning approach to palpation and ultrasound imaging skills through supplementation of traditional classroom teaching with an e-learning package.

The objective of this study was to evaluate the effectiveness of e-learning as a supplement to on-campus education for the acquisition of skills in palpation and ultrasound examination of the knee in a physiotherapy degree course. Forty-six students (28 females) from the University of Granada, with a mean age of 21.5 yrs, received 4 h of theoretical and practical on-campus training on palpation and ultrasound examination of the knee joint. They were then randomly distributed into two groups: experimental, with free access to the ECOFISIO website on musculoskeletal palpation and ultrasound assessment; and control, with access to documents and books on the topic. Structured objective clinical evaluation (SOCE) and multiple-choice questionnaire (MCQ) were used to assess the educational intervention. We also measured the time taken by the students to generate a reliable ultrasound image and to localize a specific knee structure by palpation. There was no significant intergroup difference in the acquisition of theoretical knowledge as assessed by the MCQ (p = 0.39). Scores were significantly higher in the experimental group than in the control group for skills in palpation ability (p = 0.041) and ultrasound assessment (p < 0.001) of the knee. Students in the e-learning group needed less time to palpate the musculoskeletal structure (p = 0.041) but more time (p = 0.012) to obtain their superior ultrasound images. In conclusion, these results contribute evidence that e-learning is an effective educational strategy for physiotherapy students to acquire skills in palpation and ultrasound imaging of the knee as a supplement to on-campus education.

Development disorders and increased mortality in chick embryos exposed to electromagnetic fields of 10?T and 30 Hz

Study of the body weight, third-toe length, transversal and anteroposterior cranial diameters, brain weight and mortality of embryos of Gallus domesticus at 15 and 21 days of incubation showed that their exposure to electromagnetic fields of 10 ?T intensity and 30 Hz frequency accelerated their development and produced an increase in mortality at the end of incubation (AU)
