Study compares experimental and numerical results of a supercritical airfoil behaviour in compressible flow

Research presents a contribution to the demanding field of studies on hot wire anemometry of the unsteady wake of a supercritical airfoil, based on experimental tests made on an ultrasonic wind tunnel and compared with a numerical study results. Read More →

Can asymmetries in the smile be corrected with Orthodontics?

Tooth inclination resulting from occlusal plane canting may compromise smile esthetics and lead to functional problems. Skeletal anchorage, a new treatment technique, may be used to correct these asymmetries, previously only treated by means of procedures that are either more invasive surgically or more complex mechanically.

Is there an effective way to treat bacterial diseases in fish without resistance to antibiotics?

The expansion of aquaculture increasingly exposes fish to diseases such as aeromonose caused by the bacteria Aeromonas hydrophila. To treat this bacterial infection, researchers tested the antimicrobial activity of the essential oil extracted from the Lippia origanoides plant. Results were obtained by an in vivo assay with 120 fish. Read More →

Does exposure to air pollutants cause hospitalization for respiratory diseases?

Study aimed to identify an association between exposure to air pollutants (more specifically fine particulate matter) and hospitalizations for respiratory diseases in children aged up to 10 years. The researchers found an association between exposure to this material and an increased risk of hospitalization for girls, but not a significant one for boys. Read More →

A study highlights predictors of quality of life among individuals with chronic wounds

The study evaluated quality of life among individuals with chronic wounds who were followed-up at homecare setting managed by primary health care service and specialized outpatient service in the city of Teresina, Piauí, Brazil. Results showed that variables duration, etiology, wound extension, and aspects may cause negative impact on a patient’s lifestyle. Read More →

Diarrhea in young buffaloes caused by Escherichia coli may be associated with different toxins and pathotypes of bovine

Young buffalo can become infected and develop diarrhea by the action of Escherichia coli, same bacterial agent found in diarrheic bovine calves. However, other pathotypes and toxins appear to be present in these animals. This study found a large number of STEC, NTEC and EAST-1 toxin in E. coli strains isolated from feces of buffaloes, those associated with diarrheagenic E. coli. Read More →

What is the risk of exposure to toxic compounds when consuming sparkling wines?

Compounds with toxic potential, such as the carbonyls and furfuryl alcohol, can be found in sparkling wines due to environmental contamination of the grapes or chemical reactions during the winemaking process. In this study, researchers evaluated the amount of these compounds in sparkling wines and the risk that their consumption presents to health. Read More →

Lightning strikes and ice accumulation: The use of conductive composite materials in challenging aviation solutions in review

An updated look through published studies that show the advantages brought by conductive nanostructures in effective solutions for on flight lightning current dispersion and surface deicing, minimizing the risk of accidents while improving flight efficiency through a low-weight, lower cost and lower maintenance system than others currently applied to aviation.

What is the behavior of hypocotyl of soybean cultivars over several planting seasons?

In soybean culture, the length of the hypocotyl is one of the factors that evidences the genetic variability of these cultivars. This study evaluated the length of the hypocotyl of soybean crop over several planting seasons, identifying cultivars of predictable and stable behavior in relation to this factor. Read More →

Ventilator-associated pneumonia: how to prevent?

Ventilator-associated pneumonia consists of a severe problem related with health care. To adopt measures for prevention of this condition is extremely important for patients’ safety. This study was conducted at Federal University of Sao Paulo. The objective of the study was to evaluate health professionals’ adherence to specific preventive measures for pneumonia. Read More →
