Natural environments and suicide

Natural environments and suicide mortality in the Netherlands: a cross-sectional, ecological study

Background Natural outdoor environments, such as green spaces (ie, grass, forests, or parks), blue spaces (ie, visible bodies of fresh or salt water), and coastal proximity, have been increasingly shown to promote mental health. However, little is known about how and the extent to which these natural environments are associated with suicide mortality. Our aim was to investigate whether the avai...

Isolation and Optimization of Ethanol Producing Bacteria from Natural Environments of Mazandaran Province in Iran

Ethanol producing bacteria are useful in industrial production of biofuel. There are interesting for screening of active bacteria from natural resources and introduce to biofuel industries. The present study aims to isolation of ethanol producing bacteria with characterization, optimization, and evaluation of their ethanol productivity. Samples from various fruits, plant saps and soils were scr...

Archaea in Natural and Impacted Brazilian Environments

In recent years, archaeal diversity surveys have received increasing attention. Brazil is a country known for its natural diversity and variety of biomes, which makes it an interesting sampling site for such studies. However, archaeal communities in natural and impacted Brazilian environments have only recently been investigated. In this review, based on a search on the PubMed database on the l...

Walking in Unstructured Natural Environments

In this paper we present a complete behavior-based controller that allows a six legged robot to walk in unstructured environments. The task of walking on rough terrain is decomposed in two subtasks: terrain adaptation and movement generation. The rst one maintains the stability of the robot while the second is in charge of the advance movement. We present solutions to each of these two tasks an...
