Area Code
A telephone numbering plan is a type of numbering scheme used in telecommunication to assign telephone numbers to subscriber telephones or other telephony endpoints. Telephone numbers are the addresses of participants in a telephone network, reachable by a system of destination code routing. Telephone numbering plans are defined in each of the administrative regions of the public switched telephone network (PSTN) and in private telephone networks. For public numbering systems, geographic location typically plays a role in the sequence of numbers assigned to each telephone subscriber. Many numbering plan administrators subdivide their territory of service into geographic regions designated by a prefix, often called an area code or city code, which is a set of digits forming the most-significant part of the dialing sequence to reach a telephone subscriber. Numbering plans may follow a variety of design strategies which have often arisen from the historical evolution of individual ...

Medical Marijuana
Medical cannabis, or medical marijuana (MMJ), is cannabis and cannabinoids that are prescribed by physicians for their patients. The use of cannabis as medicine has not been rigorously tested due to production and governmental restrictions, resulting in limited clinical research to define the safety and efficacy of using cannabis to treat diseases. Preliminary evidence has indicated that cannabis might reduce nausea and vomiting during chemotherapy and reduce chronic pain and muscle spasms. Regarding non-inhaled cannabis or cannabinoids, a 2021 review found that it provided little relief against chronic pain and sleep disturbance, and caused several transient adverse effects, such as cognitive impairment, nausea, and drowsiness. Short-term use increases the risk of minor and major adverse effects. Common side effects include dizziness, feeling tired, vomiting, and hallucinations. Long-term effects of cannabis are not clear. Concerns include memory and cognition problems, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Science And Religion
The relationship between religion and science involves discussions that interconnect the study of the natural world, history, philosophy, and theology. Even though the ancient and medieval worlds did not have conceptions resembling the modern understandings of "science" or of "religion", certain elements of modern ideas on the subject recur throughout history. The pair-structured phrases "religion and science" and "science and religion" first emerged in the literature during the 19th century. This coincided with the refining of "science" (from the studies of "natural philosophy") and of "religion" as distinct concepts in the preceding few centuries—partly due to professionalization of the sciences, the Protestant Reformation, colonization, and globalization. Since then the relationship between science and religion has been characterized in terms of "conflict", "harmony", "complexity", and "mutual independence", among others. Both science and religion are complex social and cu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
