John was deeply suspicious of the barons, particularly those with sufficient power and wealth to potentially challenge the king. Numerous barons were subjected to John's malevolentia, even including William Marshal, a famous knight and baron normally held up as a model of utter loyalty. The most infamous case, which went beyond anything considered acceptable at the time, proved to be that of William de Braose, a powerful marcher lord with lands in Ireland. De Braose was subjected to punitive demands for money, and when he refused to pay a huge sum of 40,000 marks (equivalent to 26,666 at the time),[nb 13] his wife and one of his sons were imprisoned by John, which resulted in their deaths. De Braose died in exile in 1211, and his grandsons remained in prison until 1218. John's suspicions and jealousies meant that he rarely enjoyed good relationships with even the leading loyalist barons.

John was deeply suspicious of who?
Answer: the barons

Ethical commitments in anthropology include noticing and documenting genocide, infanticide, racism, mutilation (including circumcision and subincision), and torture. Topics like racism, slavery, and human sacrifice attract anthropological attention and theories ranging from nutritional deficiencies to genes to acculturation have been proposed, not to mention theories of colonialism and many others as root causes of Man's inhumanity to man. To illustrate the depth of an anthropological approach, one can take just one of these topics, such as "racism" and find thousands of anthropological references, stretching across all the major and minor sub-fields.

What is the proper term for circumcision?
Answer: mutilation

Lasers emitting in the green part of the spectrum are widely available to the general public in a wide range of output powers. Green laser pointers outputting at 532 nm (563.5 THz) are relatively inexpensive compared to other wavelengths of the same power, and are very popular due to their good beam quality and very high apparent brightness. The most common green lasers use diode pumped solid state (DPSS) technology to create the green light. An infrared laser diode at 808 nm is used to pump a crystal of neodymium-doped yttrium vanadium oxide (Nd:YVO4) or neodymium-doped yttrium aluminium garnet (Nd:YAG) and induces it to emit 281.76 THz (1064 nm). This deeper infrared light is then passed through another crystal containing potassium, titanium and phosphorus (KTP), whose non-linear properties generate light at a frequency that is twice that of the incident beam (563.5 THz); in this case corresponding to the wavelength of 532 nm ("green"). Other green wavelengths are also available using DPSS technology ranging from 501 nm to 543 nm. Green wavelengths are also available from gas lasers, including the heliumneon laser (543 nm), the Argon-ion laser (514 nm) and the Krypton-ion laser (521 nm and 531 nm), as well as liquid dye lasers. Green lasers have a wide variety of applications, including pointing, illumination, surgery, laser light shows, spectroscopy, interferometry, fluorescence, holography, machine vision, non-lethal weapons and bird control.

What is the range of green wavelengths available when using DPSS technology?
Answer:
501 nm to 543 nm
