Wildlife–vehicle collisions (WVCs) are a major research focus because of increasing human health and safety concerns and the potential for biological impacts on wildlife. A key component of both understanding the causes of WVCs and designing mitigation measures is the collection and analysis of environmental and roadway data at WVC sites. However, collecting these site data can be logistically ...
OBJECTIVE This study compared the sealing ability of 3 current filling techniques in root canals shaped with 2 different rotary systems. STUDY DESIGN Eighty human extracted mandibular premolars were divided randomly into 2 similar groups of 40 each and instrumented with either ProTaper (Dentsply Maillefer, Tulsa, OK; group A) or Mtwo (VDW; Antaeos, Munich, Germany; group B) rotary systems. Ea...
Wildlife-vehicle collisions (WVC) have increased and now there is a world-wide problem related to significant mortality of wildlife, habitat fragmentation, change in behavior and even disappearance of local endangered populations. Along with these deleterious effects on wildlife, WVC can also result in injuries and deaths of humans. During the three-year monitoring, a total of 7,495 wildlife-ve...
This study investigates how 3D virtual worlds (3DVWs) support team collaboration. Based on Media Synchronicity Theory, we pose that the shared environment and avatar-based interaction allowed by 3DVWs aid convergence processes in teams working on a decision making task, leading to increased shared understanding between team members. This increases performance of decision making teams. An experi...
Introduction: Blended learning has many advantages to overcome the adult learning challenges such as limitation of time, external responsibilities and family commitments. So, this study was conducted to determine the effect of blended learning on educational outcome of discontinuous undergraduate students of operating room. Methods: This is a quasi-experimental study and educational interventi...
