Major depression is a common illness that severely limits psychosocial functioning and diminishes quality of life. In 2008, WHO ranked major depression as the third cause of burden of disease worldwide and projected that the disease will rank first by 2030.1 In practice, its detection, diagnosis, and management often pose challenges for clinicians ...

Canadian Psychiatric Association Journal, 1963
The author contends that all depressions have much more in common than they do in differences. He postulates that many depressions rest on an event, either near or far in time, which brings home to the victim the futility of striving. Such striving is derived from an effort, at an early age, to please parental figures and has been incorporated as a ...

Depression occurs in up to 45% of medically hospitalized older patients. The diagnosis of depression in this population is particularly difficult. Assessing for depression is made easier by the use of scales for screening and is best accomplished using the inclusive approach.

Tannin: An eco-friendly depressant for the green flotation separation of hematite from quartz
Minerals Engineering, 2021Reverse cationic flotation is the most known beneficiation method for the separation of fine hematite particles from silicates. In this process, the depression of the hematite surface is an essential factor.
