A medical device designed to administer a single dosage of a particular drug is called an autoinjector. Most of them are syringes which are spring loaded. Autoinjectors are easy to use by design and can be used by the patients for self-administration as well. The injection site is depends on the loaded drug. Normally it is used for injecting into the thigh or the buttocks. The need for designing injectors is associated with the hesitation to self-administer a needle-based drug. The needle tip is shielded prior to injection and also has a safety mechanism which prevents accidental injecting. The injection depth can be adjusted. The syringe needle is automatically inserted, just by pressing a button and the drug is delivered. Some autoinjectors have visual display for confirmation of completion of administration.
Scientific journal is a periodical publication intended to further progress of science, usually by reporting novel research. There are thousands of scientific journals in publication, and many more have been published at various points in the past. Most journals are highly specialized, although some of the oldest journals publish articles and scientific papers across a wide range of scientific fields. Scientific journals contain articles that are peer reviewed, to ensure that articles meet the journal's standards of quality, and scientific validity. The publication of the results of research is an essential part of the scientific method. If they are describing experiments or calculations, they must supply enough details that an independent researcher could repeat the experiment or calculation to verify the results. Each such journal article becomes part of the permanent scientific record.
