for the first time in the minkowski space, an rn 1 time-like complementary ruled surface isdescribed and relations are given connected with an asymptotic and tangential bundle of the time-likecomplementary ruled surface. furthermore, theorems are given related to edge space, central space andcentral ruled surface of this complementary ruled surface.

BACKGROUND The hospital environment has been suggested as playing an important role in the transmission of hospital-associated (HA) pathogens. However, studies investigating the contamination of the hospital environment with methicillin-resistant Staphylococcus aureus (MRSA) or Clostridium difficile have generally focused on point prevalence studies of only a single pathogen. Research evaluatin...

The paper is partly based on research done for the EU-funded (IST2004-2.4.9) project ALIS (Automated Legal Intelligent System) on Intellectual Property Law. We describe the development process of the ALIS Intellectual Property ontology from both a legal and a technical perspective. We discuss the scope and the features of this IP ontology, the lessons learned, and the problems solved. This is d...

Hospital-acquired infections (HAIs) are responsible for clinical complications with an estimated 6.1% increase in attributable deaths [1,2]. HAIs increased the length of stay in a hospital from 5.9 to 9.6 days based on one study of over 1,250 patients [1]. Concomitantly, estimated healthcare costs double for patients with HAIs [1,3]. As many as 27% of hospital ward patient rooms are contaminate...

The role that environmental contamination might play as a reservoir and a possible source of Methicillin-resistant Staphylococcus aureus (MRSA) for patients and personnel at equine veterinary hospitals remains undefined, as the environment has only been monitored during outbreaks or for short periods. Therefore, the objectives of this study were to determine the monthly presence, distribution, ...

BACKGROUND Pressure ulcers are a prevalent and global issue and support surfaces are widely used for preventing ulceration. However, the diversity of available support surfaces and the lack of direct comparisons in RCTs make decision-making difficult. OBJECTIVES To determine, using network meta-analysis, the relative effects of different support surfaces in reducing pressure ulcer incidence a...

BACKGROUND The purpose of this study was to determine the effectiveness of copper-impregnated composite hard surfaces and linens in an acute care hospital to reduce health care-associated infections (HAIs). METHODS We performed a quasiexperimental study with a control group, assessing development of HAIs due to multidrug resistant organisms (MDROs) and Clostridium difficile in the acute care ...
