CompTIA's A+ exams are comprehensive, with topics that include hardware interfaces, printers, network technologies, operating systems, security issues, troubleshooting, and much more. In Professor Messer's A+ video course, there are hundreds of pictures, tables, documentation, and other details that you need to know for the exam. After you've read the books and watched the videos, you'll need a set of notes to help you remember the technical details from the CompTIA A+ exam objectives. All of the unique charts, pictures, and tables from the Professor Messer video series have been incorporated into these easy-to-read Course Notes.
There are few IT credentials as challenging or rewarding as the network certifications offered by Cisco Systems. If you're planning a career in networking, then you'll probably earn at least one Cisco certification during your career. After you've read the books, watched the training videos, and worked through hands-on labs, you'll need a set of notes to help you remember the technical topics and CLI commands for your exam. My Course Notes are the perfect companion for your ongoing Cisco ICND1 studies.
Optical antennas can be used to dramatically increase the rate that semiconductors spontaneously emit photons. While traditional LEDs are limited in bandwidth due to the "slow" rate of spontaneous emission, antenna-enhanced LEDs have the potential to be a fast, efficient, nanoscale light emitter. Traditionally, lasers have dominated LEDs as the emitter in optical interconnects due to a 200x speed advantage of stimulated emission over spontaneous emission. This paradigm may be reversed by coupling LEDs to optical antennas. In fact, antenna enhanced spontaneous emission can be faster than the fastest stimulated emission. Spontaneous emission originates from dipole fluctuations within the emitt...
100 years in the Golden Heart City. Discovering gold, trading post, Alaska Railroad, the disater of the 1967 flood and the Trans-Alaska Oil Pipeline. Continuing into the growing modern city at the start of its second century.
Mercer (Messer) Norton (ca.1750-ca.1800) moved from Fairfax (later Loudon) County, Virginia to Randolph County, North Carolina, married Martha Higgins, moving in 1790 to Burke County, North Carolina, and later to Wayne County, Kentucky. Descendants lived in North Carolina, Kentucky, Alabama, Arkansas, Texas, Arizona, Utah, California and elsewhere.
Because marijuana is a Schedule I drug under the Controlled Substances Act, the therapeutic benefits of cannabis are no longer mentioned in the formal education of health care professionals. Doctors who do learn of the drug’s therapeutic value are often intimidated by its illegal status. Thus millions of patients afflicted with such illnesses as glaucoma, AIDS, cancer, multiple sclerosis, spinal cord injuries, seizure disorders and chronic pain are denied access to information about the drug’s benefits and, in many cases, suffer needlessly. Straightforward and nonpoliticized information on the therapeutic uses of cannabis is provided here by medical, legal and scientific professionals. Legal issues, a worldwide history of therapeutic cannabis and a discussion of its pharmacology are covered. Specific medical uses are then examined, including its application for sufferers of cancer, AIDS, glaucoma, and seizure disorders, and its potential use in psychiatry. Dosages and administration of cannabis are explored, along with considerations on the use of the drug during pregnancy and the risks of addiction and dependency.
