Waldemar Wilhelm (1913-1994) was honored by the Asociación Colombiana de Cirugía Oral y Maxilofacial (Colombian Association of Oral and Maxillofacial Surgery) as the Father of Oral and Maxillofacial Surgery in Colombia. ... -
Walking robot bio-inspired by Insect’s locomotion for carbon dioxide diagnostic indexed in the air
The spiders, in comparison with the majority of others animals, it has the ability to access all kind of environment where others animals or even the humans can’t. Those attributes of the spiders are taken into this project ... -
Well-being, behavioral patterns and cycling crashes of different age groups in Latin America: Are aging adults the safest cyclists?
Objectives This study aimed at analyzing the cycling safety-related factors and the mental health indicators of elderly cyclists in comparison with other age groups. Methods For this cross-sectional study, we analyzed the ... -
What does the Shinyei PPD42NS low-cost dust sensor really measure?
(International Journal of Environmental Science and Development, 2021)Abstract—Deteriorating air quality is of great concern around the world. Recently, citizen scientists, researchers, and many others have used low-cost devices such as the Shinyei PPD42NS dust sensor to measure particulate ... -
What’s new in the treatment of enterococcal endocarditis?
Enterococcus spp. are among the common pathogens causing infective endocarditis (IE). Despite major medical advances and new potent antimicrobial agents, the mortality has not significantly improved for several decades. ... -
When object clitisation and climbing happen alone, and when they dance cheek to cheek: Selective impairment in Spanish agrammatism
Previous studies have shown that production of clitics in agrammatic Broca’s aphasia is compromised, either by analyzing spontaneous speech (Nespoulous et al., 1988; Reznik et al.,1995; Stavrakaki and Kouvava, 2003; ... -
When the brain simulates stopping: neural activity recorded during real and imagined stop-signal tasks
It has been suggested that mental rehearsal activates brain areas similar to those activated by real performance. Although inhibition is a key function of human behavior, there are no previous reports of brain activity ... -
Whole-genome analyses of enterococcus faecium isolates with diverse daptomycin MICs
Daptomycin (DAP) is a lipopeptide antibiotic frequently used as a "last-resort" antibiotic against vancomycin-resistant Enterococcus faecium (VRE). However, an important limitation for DAP therapy against VRE is the emergence ... -
Whole-genome analysis of a daptomycin-susceptible enterococcus faecium strain and its daptomycin-resistant variant arising during therapy
Development of daptomycin (DAP) resistance in Enterococcus faecalis has recently been associated with mutations in genes encoding proteins with two main functions: (i) control of the cell envelope stress response to ... -
Whole-genome sequencing accurately identifies resistance to extended-spectrum β-lactams for major gram-negative bacterial pathogens
Background There is marked interest in using DNA-based methods to detect antimicrobial resistance (AMR), with targeted polymerase chain reaction (PCR) approaches increasingly being incorporated into clinical care. Whole-genome ... -
Whole-genome sequencing of staphylococcus epidermidis bloodstream isolates from a prospective clinical trial reveals that complicated bacteraemia is caused by a limited number of closely related sequence types
Objectives The significance of isolating Staphylococus epidermidis from a blood culture is highly heterogeneous, ranging from contamination to an indication of a serious infection. Herein we sought to determine whether ... -
Work environment, stress, and driving anger: a structural equation model for predicting traffic sanctions of public transport drivers
Public transport is an effective and sustainable alternative to private vehicle usage, also helping to reduce the environmental impact of driving. However, the work environment of public transport operators is full of ... -
Work in Progress: Native language consistency effect on learners' introduction to block-based instructional technologies
This lightning talk discusses how cultural factors such as learners' native language may impact the understanding of CS concepts. We present findings from an evaluation we conducted with adult participants, Native-English ... -
Work stress and health problems of professional drivers: A hazardous formula for their safety outcomes
Background Several empirical studies have shown that professional drivers are a vulnerable occupational group, usually exposed to environmental stressors and adverse work conditions. Furthermore, recent studies have ... -
Work stress, fatigue and risk behaviors at the wheel: Data to assess the association between psychosocial work factors and risky driving on Bus Rapid Transit drivers
This Data in Brief (DiB) article presents a hierarchical multiple linear regression model that examine the associations between psychosocial work factors and risk behaviors at the wheel in Bus Rapid Transit (BRT) drivers ... -
Working conditions, job strain, and traffic safety among three groups of public transport drivers
Background Working conditions and psychosocial work factors have acquired an important role explaining the well-being and performance of professional drivers, including those working in the field of public transport. This ... -
Wound healing of the laterally positioned flap: A histomorphometric assessment
he aim of this study was to histomorphometrically assess the soft tissue anatomy in single gingival recessions (GR) treated with a laterally positioned flap (LPF). Five patients presenting maxillary first molars with GR ... -
WSES consensus conference guidelines: monitoring and management of severe adult traumatic brain injury patients with polytrauma in the first 24 hours
The acute phase management of patients with severe traumatic brain injury (TBI) and polytrauma represents a major challenge. Guidelines for the care of these complex patients are lacking, and worldwide variability in ... -
X-band and Ku-band VCSEL-based optoelectronic oscillators using on-chip laser
We present the results of the implementation of two VCSEL-based optoelectronic oscillators (VBO) using one on-chip 850-nm vertical-cavity surface-emitting laser (VCSEL). The reported VBOs are implemented at 10 and 12 GHz ...
