The damage mechanisms of metallic components produced by process laser powder bed fusion differ significantly from those typically observed in conventionally manufactured variants the same alloy. This is due to unique microstructures additively materials. work focusses on study evolution creep stainless steel 316L specimens fusion. X-ray computed tomography used unravel influence process-specif...

knowledge of airflow resistance is an important consideration in designing an appro-priate ventilation system and for proper fan selection. an airflow resistance device was designed and fabricated to measure the airflow resistance of potatoes. the device the composed of an air compressor, a rotameter, a cylindrical bin to contain the potatoes and an inclined u-tube manometer. airflow resistance...

introduction spinal cord injury without radiological abnormality (sciwora) is a rare entity and usually involves the cervical spine. thoracic spine involvement is very rare due to the stability provided by the rib cage. the mechanisms of injury and pathophysiology are still debatable. case presentation we present a case of an adult male who had road traffic accident and presented with paraplegi...

The bed bug, Cimex lectularius L., like other bed bug species, is difficult to visually locate because it is cryptic. Detector dogs are useful for locating bed bugs because they use olfaction rather than vision. Dogs were trained to detect the bed bug (as few as one adult male or female) and viable bed bug eggs (five, collected 5-6 d after feeding) by using a modified food and verbal reward sys...

Hastelloy X (HX) is a Ni-based superalloy which suffers from high crack susceptibility during the laser powder bed fusion (LPBF) process. In this work, the microstructure of as-built HX samples was rigorously investigated to understand the main mechanisms leading to crack formation. The microstructural features of as-built HX samples consisted of very fine dendrite architectures with dimensions...

Background: This study aims to describe the community perceptions regarding an insecticide-treated bed net (ITN) programme in Burkina Faso, where communities were randomised to either ITN social marketing combined with free ITN distribution through antenatal care services (intervention A) or ITN social marketing only (intervention B). Methods: For this descriptive qualitative study data were co...

The linear stability of an erodible sediment bed beneath a turbidity current is analysed, in order to identify potential mechanisms responsible for the formation of longitudinal gullies and channels. On the basis of the three-dimensional Navier–Stokes equations, the stability analysis accounts for the coupled interaction of the three-dimensional fluid and particle motion inside the current with...
