Nanoemulsions are nano-sized emulsified systems. They can be produced by different methods, which can be classified as low and high energy methods. The decrease in the size of formed globules allows them to penetrate different barriers such as the skin or the gastrointestinal barrier. Thus, the encapsulation of active compounds through nanoemulsions makes it possible to improve their bioavailability and to offer protection against environmental conditions such as temperature, humidity, or UV radiation. In the same way, it is possible to formulate double nanoemulsions to encapsulate hydrophilic and lipophilic molecules in one single globule. Their formulation process requires a comprehensive analysis involving physical and thermodynamic approaches. [ABSTRACT FROM AUTHOR]

Introduction: Pneumomediastinum or Hamman syndrome usually appears in young males; any condition provoking Valsalva maneuvers can be a predisposing factor. Clinical case: We report an 18 years old male admitted to the emergency room for polydipsia, polyphagia, malaise, profuse vomiting and chest pain. A diabetic ketoacidosis was diagnosed and a chest X ray film showed a pneumomediastinum. The patient was compensated metabolically and an esophageal X ray examination discarded esophageal perforation. He was discharged in good conditions seven days after admission.

This work show the study in small steam turbine capacity of generation in Cuban thermoelectric power station to relative with statistical influence between steam process parameters regarding absolute vibration parameter, in the steam housing measurements. Themselves use database as steam on-line monitoring systems. Expose the existing relation between the principal selection parameters for this study. [ABSTRACT FROM AUTHOR]

This diagnosis has been carried out in a total of 14 induction motors, all them of squirrel cage and of 6 000 volts. Reference will be made to the last carried out diagnosis that it is a motor of a bomb of water of feeding boiler type 4A3M- 2500/6000 CT4 of a generating unit of electricity of 100 MW. By means of the techniques of diagnosis employees it was possible to determine breaks of bars in the cage of squirrel of the rotor in the motor. [ABSTRACT FROM AUTHOR]

Lower limb asymmetry is common in adolescents and may be a factor causing pain the spine and may also be associated with functional scoliosis of the lumbar region. Spine dysfunctions causing work related disabilities are highly prevalent throughout the world This public health issue is of multifactorial origin and affects he majority of those in mid life, the result of pelvic drop and increased lumbar lordosis. The aim of this work was to study the performance of our teenagers with respect to the mentioned variables. We analyzed 49 panoramic radiographs of the spines of schoolchildren between 13 and 17 years, 24 male and 25 female in the city of Temuco, Chile. Of total subjects 33 showed some degree of pelvic tilt which corresponds to 67.3% of subjects. In 27 cases subjects were in the 1 to 10mm range and 4 subjects in the 11 to 15mm range. In 16 subjects no deviation was observed in frontal plane and 33 subjects had some degree of deviation. It is important to know these parameters in our adolescent population, to include formal education prevention in all aspects of life and to reduce the symptoms and costs of care and rehabilitation.
