In this work, three experiments are reported that studied the use and interaction of navigation strategies both during the learning of a virtual environment and during subsequent route planning tasks. Special interest concerned the role of regions within the environments. Results from Experiment 1 suggest that the regions are perceived and encoded in spatial memory very early during the process...

abstract several medications have been proposed as the first line drugs in the treatment of migraine attack. however, the low efficacy, potential complications of medications and the intolerance of some patients for oral route due to nausea and vomiting establish a difficult situation in some migraine patients. this report describes a dramatic pain relief with 60 mg of intravenous propofol in a...

Now a day's traffic jam is a very common problem in all the cities. Every day people spend valuable times uselessly because of traffic jam. We have proposed a system that came up with a solution which can reduce traffic jam dramatically. This is a web based application. People will just check the status of the route they are heading for whether the route consisting medium, heavy or less tr...

Subclavian route is a standard way of performing a permanent pacemaker. However in cases with superior vena caval or bilateral subclavian occlusion and bilateral infection of pacemaker site, alternative site is warranted. Epicardial route needs general anesthesia and has its own problems. Iliofemoral route has been used previously but has more lead related problems and patient discomfort. Here ...

oral contraceptive pills have several side effects especially on the gastrointestinal tract and liver. absorption of low dose (ld) pills by the vaginal route avoids the first pass of the steroids through these tracts and probably has fewer side effects. this study was a cohort study for evaluation of side effects and acceptability of ld pills administered by the vaginal route. in a clinical tri...

Although the optimal route of administration of opioids is by mouth, some patients may require alternative routes during the course of their illnesses for several reasons. These include bowel obstruction, severe emesis, or severe dysphagia. In these cases, the alternatives include the subcutaneous or rectal route. The transdermal route also provides a simple, comfortable method that produces st...

Triangular silver nanoplates, of different orientations, and other nanostructures were successfully synthesized using the Horizontal Vapor Phase Crystal (HVPC) Growth technique for antimicrobial purposes in this study. This finding demonstrates HVPC as an alternative and simple technique to synthesize ordered silver nanomaterials for antimicrobial study. Keyword —alternative method, antimicrobi...

Marine spatial planning provides a comprehensive framework for managing multiple uses of the marine environment and has the potential to minimize environmental impacts and reduce conflicts among users. Spatially explicit assessments of the risks to key marine species from human activities are a requirement of marine spatial planning. We assessed the risk of ships striking humpback (Megaptera no...

Wireless networks have become so widespread, it is beneficial to determine the ability of cellular networks for localization. This property enables the development of location-based services, providing useful information. These services can be improved by route prediction under the condition of using simple algorithms, because of the limited capabilities of mobile stations. This study gives alt...
