Awake Craniotomy without Invasive Blood Pressure Monitoring.

Objective: To assess the safety of foregoing invasive monitoring in a select group of patients undergoing awake craniotomy for supratentorial tumor resection.

Methods: Awake craniotomies were performed for tumor resection without invasive blood pressure monitoring when there was no preexisting cardiopulmonary indication as determined by the attending anesthesiologist according to institutional protocol. Noninvasive monitoring was performed every 3-5 minutes intraoperatively and then every 15 minutes in the recovery room for 4 hours before transfer to the ward.

The Search as Learning Spaceship: Toward a Comprehensive Model of Psychological and Technological Facets of Search as Learning.

Using a Web search engine is one of today's most frequent activities. Exploratory search activities which are carried out in order to gain knowledge are conceptualized and denoted as (SAL). In this paper, we introduce a novel framework model which incorporates the perspective of both psychology and computer science to describe the search as learning process by reviewing recent literature.

Substrate Type Influences the Structure of Epiphyte Communities and the Growth of Seedlings.

Epiphytes colonizing adult seagrasses highly contribute to seagrass ecosystem functioning and plant growth. Yet, little information exists on epiphytic communities developing on seagrass seedlings. Moreover, for some species our knowledge about seedling performance is limited to early establishment phases, and the role of substrate type in affecting their growth is still unclear.

Nutrient Loading Fosters Seagrass Productivity Under Ocean Acidification.

The effects of climate change are likely to be dependent on local settings. Nonetheless, the compounded effects of global and regional stressors remain poorly understood. Here, we used CO vents to assess how the effects of ocean acidification on the seagrass, Posidonia oceanica, and the associated epiphytic community can be modified by enhanced nutrient loading.
