Phenomenological differences between older patients with late- and early-onset depression may reflect differences in aetiology and neuropathological processes involved in these two types of depression. Early- onset depression has been mainly correlated to a family history of depression while late-onset depression has been principally correlated to vascular dysfunction. The same cortical and sub...

In laboratory medicine, several studies have described the most frequent errors in the different phases of the total testing process, and a large proportion of these errors occur in the pre-analytical phase. Schemes for registration of errors and subsequent feedback to the participants have been conducted for decades concerning the analytical phase by External Quality Assessment (EQA) organizat...

the management of sedimentation problems in rivers and reservoirs depend greatly on the sediment yield from the catchment land surface. in this research the effects of biological measures and ranges enclose on suspended load in two sub-catchments of kakhk experimentalwatershed in gonabad has been studied. this catchment contains both control and experimental sub-catchments. these sub-catchments...

Sub-Saharan Africa has been the location of intense conservation planning since the colonial era. Under the auspices of wilderness protection, colonial authorities established national parks largely for the purpose of hunting and tourism while forcibly evicting indigenous populations. Concerns about the ethical and economic impacts of protected areas have generated interest in community conserv...

In this paper, a large environment is divided into sub-areas to enable a robot to apply precise localization technology efficiently in real time. Sub-area features are represented in a feature information system so that conventional machine learning or data mining approaches can be applied to identify the sub-areas. However, conventional representations with a single body of knowledge encounter...
