Membranes are an energy efficient separation technology that are now the basis for many water treatment and food processing applications. However, there is the potential to improve the operating performance of these separations and to extend the application of membranes to energy production, gas separations, organic solvent-based separations, and biomedical applications through novel membrane materials. This book contains 20 chapters written by leading academic researchers on membrane fabrication and modification techniques and provides a comprehensive overview on the recent developments of membrane technology. Membranes can be manufactured from a range of materials including polymeric compounds, and ceramic materials, and both these materials are considered in the book. There are 5 chapters on water and wastewater membranes that cover the fabrication of thin film (TFC) composite membranes for nanofiltration(NF)/reverse osmosis (RO)/forward osmosis (FO) applications, stimuli responsive membranes, electrospun membranes, porous ceramic membranes, and polymeric ultrafiltration (UF) manufacture and modification. There are another 6 chapters on gas separation that consider carbon membranes, zeolite membranes, silica template and metal oxide silica membranes, TFC membranes, silica membranes, and metal organic framework (MOF) membranes. Zeolite membranes are also considered for organic solvent applications, as are solvent-resistant membranes manufactured by phase inversion, ceramic-supported composite membranes, and ceramic NF membranes. The emerging areas of membranes for energy and biomedical applications have 3 and 2 chapters, respectively. Energy applications consider ion exchange membranes for use in fuel cells, membranes for electrodialysis, and membranes for use in microbial fuel cells. For biomedical applications the chapters focus on hemodialysis membranes and redox responsive membranes.

Truly a medicine for body and soul, one of cannabis’s greatest gifts is its remarkable potential for spiritual healing and awakening. In this authoritative guide, editor Stephen Gray and 17 other influential voices of the modern cannabis movement explore the spiritual benefits of cannabis and offer guidance on how to interact with the intelligence of this plant ally, a companion and supporter of humanity for millennia. Exploring cannabis spirituality in practice, Gray’s chapters examine dosage, strains, and methods of intake; the use of cannabis to open the creative channels; how to conduct group ceremonies with cannabis; and cautions and counterindications for cannabis use. We hear from Chris Bennett on the religious and ritual use of cannabis from pre-biblical times to the present, Joan Bello on marijuana and the body-mind connection, Dee Dussault on ganja yoga, Kathleen Harrison on humanity’s co-evolution with cannabis, and cannabis shaman Hamilton Souther on working with the spirit of cannabis. The contributors explore the spiritual future of this plant ally as well as the ritual use of cannabis by the Rastafarians of Jamaica and the Sadhus of India. The chapters from Brazilian ayahuasca shaman Mariano da Silva and ayahuasca apprentice Francisco present wisdom on comingling the sacramental medicines of cannabis and ayahuasca.

Una guía sobre los beneficios y desafíos del uso del cannabis en la práctica espiritual• Incluye capítulos de 18 voces autorizadas e influyentes del movimiento cannábico moderno, incluidos Kathleen Harrison, Joan Bello, Hamilton Souther, Steven Hager, Chris Bennett, Dee Dussault, Jeremy Wolff y Roger Christie• Explora el uso de la marihuana en una amplia gama de prácticas espirituales, incluida la meditación, yoga, canto, visualización, chamanismo, ceremonias grupales, trabajo con otros enteógenos y como ayuda creativaVerdaderamente, una medicina para el cuerpo y el alma, uno de los mayores dones del cannabis es su notable potencial para la sanación y el despertar espiritual. En esta guía autorizada, el editor Stephen Gray y otras 17 voces influyentes del movimiento cannábico moderno exploran los beneficios espirituales del cannabis y ofrecen orientación sobre cómo interactuar con la inteligencia de esta planta aliada, compañera y defensora de la humanidad durante milenios.Al explorar la espiritualidad del cannabis en la práctica, los capítulos de Gray examinan las dosis, cepas y métodos de ingesta; el uso del cannabis para abrir canales creativos; cómo realizar ceremonias grupales con cannabis, y las precauciones y contraindicaciones para su consumo. Chris Bennett habla sobre el uso religioso y ritual del cannabis desde los tiempos prebíblicos hasta el presente, Joan Bello sobre la marihuana y la conexión cuerpo-mente, Dee Dussault sobre el ganja yoga, Kathleen Harrison sobre la coevolución de la humanidad con el cannabis, y el chamán cannábico Hamilton Souther sobre cómo trabajar con el espíritu del cannabis. Los colaboradores exploran el futuro espiritual de esta planta aliada, así como el uso ritual del cannabis por parte de los rastafaris de Jamaica y los sadhus de la India. Los capítulos del chamán brasileño de ayahuasca Mariano da Silva y del aprendiz de ayahuasca Francisco presentan conocimientos sobre la combinación de las medicinas sacramentales del cannabis y la ayahuasca.Al revelar el potencial de "la planta del pueblo" para mejorar una amplia variedad de prácticas espirituales, como la meditación, el yoga, el canto, la visualización, el chamanismo, el trabajo espiritual y las exploraciones con otros enteógenos, esta guía muestra cómo el cannabis es un aliado eficaz en el viaje de despertar, probando que es capaz de desbloquear la energía receptiva en todos nosotros para ayudar a sentirnos conectados con la naturaleza, con los demás y con nosotros mismos.
