Quaker Testimony Against Slavery and Racial Discrimination

This anthology has been compiled at the suggestion of the Race Relations Committee of the (British) Society of Friends, who wanted to record the development of Friends\u27 testimony against slavery and racial discrimination. The extracts have been grouped under two headings Individual Witness and Corporate Witness . An effort has been made under the second heading to trace the growth of the testimony, but in general the passages have been chosen for their intrinsic interest and to illustrate the depth and strength of the witness.https://digitalcommons.georgefox.edu/quakerbooks/1073/thumbnail.jp

Nociones preliminares de geometría algebraica

Se introducen las nociones elementales de Geometría algebraica y algunos teoremas, como el Teorema de la Base de Hilbert y el Teorema de los Ceros de Hilbert; dando una interpretación tanto algebraica como geométrica

El grupo Spin de SO(n)

Se introducen las nociones elementales de Cuaterniones, álgebra de Clifford y grupos Spin. Se construye además empleando el concepto de álgebra de Clifford el doble cubrimiento de SO(n), Spin(n

Optimization of femtosecond laser processing in liquids

In this paper we analyze femtosecond laser processing of metals in liquids searching for optimal conditions for predictable ablation. Incident laser pulses are stretched or compressed, self-focused and scattered on bubbles and on surface waves in the liquid environment. Influence of these effects on the laser intensity distribution on the target surface is discussed and optimal processing parameters are suggested

Flujos de detritos y aluviones históricos en la cuenca del río Blanco (32°55'-33°10' y 69°10'-69°25'), Mendoza

La cuenca del río Blanco está sometida a un clima árido con precipitaciones medias anuales de 400 mm. Las lluvias intensas y de corta duración están concentradas en los tres meses de verano actuando frecuentemente como disparadoras de flujos de detritos y aluviones en el Cordón del Plata y generando variaciones en el caudal del río Blanco por aporte extraordinario de estos eventos. Información sobre la ocurrencia de flujos de detritos y aluviones reportados entre 1942 y 2001 en la cuenca del río Blanco fue recopilada y analizada a partir de crónicas periodísticas, datos aportados por los pobladores, registros pluviométricos de la zona y años de anomalías climáticas, tratando de establecer la precipitación mínima requerida para desestabilizar estas pendientes. Durante el período mencionado se registraron 18 flujos de detritos y aluviones, de los cuales los más importantes ocurrieron en 1960, 1967, 1970 y 1982; y produciéndose dos eventos en los años 1954, 1967, 1982 y 1993, sin embargo la intensidad de los eventos de flujos de detritos y aluviones parece incrementarse durante los años de anomalías climáticas correspondientes a la fase cálida del fenómeno ENOS "El Niño".Fil: Paez, Maria Solange.

Burdens and Resources of Staff of a Specialized Ward for Neuropalliative Care: A Cross-Sectional Survey

Palliative care adds significant burdens to healthcare workers. In neuropalliative care (NPC), additional challenges include patient symptom burdens, such as impairments in mobility, cognition, and communication. After one year of operating the first NPC ward in Germany, we assessed burdens, resources, and the number of deaths perceived as stressful. NPC physicians and nursing staff were compared with the team of other neurological wards, including a stroke unit. The assessment took place between March 2022 and May 2022. All 64 team members were contacted; the responder rate was 81%. The perceived burden was high but did not differ between groups. There were no differences between the NPC- and the neurological wards in the number of deaths perceived as stressful. However, rather than the number of deaths, the circumstances of dying influence the perceived distress. The resources mentioned were similar between groups, with the team and private life being most important. Communication difficulties were frequently cited as stressful, whereas successful communication was identified as a resource
