The relatively new technique of solid phase microextraction (SPME) is an important tool to prepare samples both in the lab and on-site. SPME is a "green" technology because it eliminates organic solvents from analytical laboratory and can be used in environmental, food and fragrance, and forensic and drug analysis. This handbook offers a thorough background of the theory and practical implementation of SPME. SPME protocols are presented outlining each stage of the method and providing useful tips and potential pitfalls. In addition, devices and fiber coatings, automated SPME systems, SPME method development, and In Vivo applications are discussed. This handbook is essential for its discussion of the latest SPME developments as well as its in depth information on the history, theory, and practical application of the method. - Practical application of Solid Phase Microextraction methods including detailed steps - Provides history of extraction methods to better understand the process - Suitable for all levels, from beginning student to experienced practitioner
Libro que propone ideas concretas, técnicas, sugerencias y prácticas para estar en paz con uno mismo y convivir positivamente y en armonía, en especial en el ámbito de las relaciones personales y sociales. Para comprender el origen y las causas de los conflictos de la vida cotidiana.
La educación, desde sus posibilidades éticas, pretende clarificar las conciencias para transformar el mundo; por eso, indagar por los elementos para configurar la paz en el siglo XXI no consiste en asumir que esta sea una meta, sino que es en sí misma un camino, un devenir constante, en el que la Universidad reconoce una utopía, no como algo inalcanzable, sino como un lugar posible que se realiza en acciones y prácticas concretas, pero que se fundamenta en la posibilidad de la crítica como la interrogación de los discursos y las acciones que llevamos a cabo, para mirar en estos sus propios límites y posibilitar otras formas de ser, otras formas de aparecer en el mundo. La paz que se propone, entonces, parte de las acciones de los individuos desde la ética como una práctica, que es necesariamente reflexiva y que implica a su vez prácticas de libertad y ejercicios de liberación. El llamado de la Cátedra Institucional Lasallista, en el 2102, es a delinear mapas para la configuración de los territorios que queremos para contribuir en la formación de los hombres que acompañamos en su educación.

El libro recoge las reflexiones que enmarcan la reconciliación como una posibilidad real y punto de partida para la construcción de un tejido social que paulatinamente siembre la paz, no como utopía, sino como una expresión concreta de relación y acción, tal como lo muestra el mismo texto cuando aborda en su parte final algunas experiencias concretas, nacionales e internacionales que han dejado en los contextos sociales en los que se han desarrollado evidencias significativas de una cultura cierta y posibe.
This book aims to raise awareness of IgG4-related sclerosing cholangitis among practicing physicians and to equip readers with a sound understanding of the principles of diagnosis and treatment. Clinical, serological, and histopathological features are clearly described and imaging appearances on all relevant modalities are illustrated, covering the bile duct and other involved organs. Differential diagnosis from other diseases, including primary sclerosing cholangitis and cholangiocarcinoma, is precisely explained. Information is then presented on all significant current and emerging therapeutic strategies, including steroids, immunosuppressive drugs, and rituximab. Finally, attention is drawn to significant prognostic features. While IgG4-related sclerosing cholangitis is now a widely acknowledged condition, most practitioners are still liable to misdiagnose it owing to a lack of familiarity with its presenting features. This book should help to rectify the situation and will be an asset for all who may encounter the disease in clinical practice.
