A time series study described the trend in motor vehicle accidents from 1991 to 2000, using data from the State Transit Department in Salvador, Bahia State, Brazil. Rates were calculated for total motor vehicle accidents, number of casualties, and standardized mortality based on population and number of vehicles, comparing two periods (1991-1994 and 1995-2000), before and after the adoption of safety measures including compulsory seat belt use and the new National Transit Code (NTC). Vehicle accident and casualty rates were high and showed little variation during the study period. The mortality rate decreased from 25.7/100,000 inhabitants in 1995 to 18.1/100,000 in 1998 and remained stable thereafter. The only significant difference (p < 0.001) was in the mean motor vehicle accident mortality rate before and after the intervention. The case fatality rate decreased from 10.7% (1995) to 7% (2000). Although still representing a major public health problem in this important metropolitan area, the decrease in motor vehicle accident mortality was possibly due to interventions in 1995 and expanded NTC measures in 1998. Greater efforts to change driver and pedestrian behavior could further decrease the high number of accidents and related mortality.

With the growing need for sustainable transportation solutions, understanding the relationship between driving characteristic parameters, vehicle type, and their impact on emissions and fuel consumption over real driving scenarios is becoming increasingly important. In this paper, four conventional vehicles and one hybrid vehicle with different technologies were compared in four distinct routes in Tehran city. Nineteen real driving cycles were generated using widely employed K-means and PCA algorithms.

Introduction: Bilateral simultaneous rotational ankle fractures are an unusual phenomenon that remains unreported in the English literature, and to our knowledge, about 10 cases have been reported. The aim of the study was to evaluate and report clinical outcomes of bilateral simultaneous ankle fractures in our institution.
Case Reoprt: We conducted a review of our 2-year experience with patients who had simultaneous bilateral fractures of the ankles and were treated at our institution.

"Situs inversus with levocardia" refers to the mirror-image lateral orientation of the abdominal organs with a normally oriented, left-sided heart. This anatomical anomaly arises from abnormalities in the biochemical signaling systems mediating embryological development. We present a case of situs inversus with levocardia incidentally discovered in a healthy 24-year-old male during workup following a motor vehicle collision.

Spinal cord injury (SCI) results in functional deficits below the injured spinal level. The descending serotonergic system in the spinal cord is critically involved in the control of motor and autonomic functions. Specifically, SCI damages the projections of serotonergic fibers, which leads to reduced serotonin inputs and increased amounts of spinal serotonergic receptors.

In the study of structural materials, the analysis of fracture and deformation resistance plays an important role, particularly in materials widely used in the construction industry, such as poly(vinyl chloride) (PVC). PVC is a popular material used, among others, in the manufacture of window profiles, doors, pipes, and many other structural components. The aim of this research was to define the influence of the degree of milling of the glass-fibre-reinforced composite on the strength of the window frame welds, and in the next step, to propose new welding parameters to obtain sufficient strength properties that allow reducing the cost of the technological welding operation.
