2. NUMERICAL AND EXPERIMENTAL INVESTIGATION OF AIR-WATER SYSTEM TO SIMULATE BUBBLE DYNAMICS IN LIQUID SODIUM POOL
Abstract The dynamics of rising bubbles in a liquid sodium pool plays a significant role in the estimation of the radiological source term during anticipated transients and normal operation of a fast reactor. Sodium is chemically reactive with air and water. Therefore, carrying out experiments using sodium on a reactor scale level requires extra precautions.

4. A novel simplified scoring system for predicting mortality in emergency colorectal surgery: prediction model development
ABSTRACT BACKGROUND: Despite advances in surgical approaches, emergency colorectal surgery has high mortality and morbidity. OBJECTIVE: We aimed to create a simple and distinctive scoring system, for predicting mortality among patients undergoing emergency colorectal surgery. DESIGN AND SETTING: Prediction model development study based on retrospective

5. Clinical comparison between a percutaneous hydraulic pressure delivery system and balloon tamp system using high-viscosity cement for the treatment of osteoporotic vertebral compression fractures
OBJECTIVES: Osteoporotic vertebral compression fractures (OVCFs) affect the elderly population, especially postmenopausal women. Percutaneous kyphoplasty is designed to treat painful vertebral compression fractures for which conservative therapy has been unsuccessful. High-viscosity cement can be injected by either a hydraulic pressure delivery system (HPDS

6. Pattern recognition of abscesses and brain tumors through MR spectroscopy: Comparison of experimental conditions and radiological findings
Abstract Introduction The interpretation of brain tumors and abscesses MR spectra is complex and subjective. In clinical practice, different experimental conditions such as field strength or echo time (TE) reveal different metabolite information. Our study aims to show in which scenarios magnetic resonance spectroscopy can differentiate among brain tumors,

10. Avaliação dos resultados do uso de haste inflavel auto blocante intramedular (HEIA) para o tratamento de fraturas e falhas de fixação ossea dos ossos longos / Clinical and radiological results from the of a self-locking intramedullary expanding nailing system (SLINS) fixion trade mark for treating failures in long bone fractures
We present a self-locking intramedullary nailing system (Fixion®) for treatment of long bones fractures and failed fixation systems. The features of this system and the advantages of the technique include: fixation along the entire length of the nail, lack of proximal and distal interlocking screws, optional reaming, reduced exposure of the surgeon X-Ray an

11. Adaptation of an individual external monitoring system for gamma and x ray evaluation of the individual dose equivalent "HP(10)", utilizing a photographic dosemetry technique / AdaptaÃÃo de um sistema de monitoraÃÃo individual externa para raios x e gama para avaliaÃÃo do equivalente de dose pessoaL âHp(10)â, utilizando a tÃcnica da dosimetria fotogrÃfica
Individual monitoring evaluates external souces of ionizing radiation X, γ, β and n, to which workers are occupationally exposed, for ensuring safe and acceptable radiological conditions in their places of employment. The dose received by workers should attend the limits authorized by national regulatory organs. Nowadays, there are two radiometric
