Possibility of using ionizing radiation treated sludge from drinking water treatment plant as fertilizer in agriculture: Effects of aging.

Using ionizing radiation in treating waste sludge from a drinking water treatment plant is a well-known technique. Sludge treated with ionizing radiation can be used as fertilizer in agriculture. In this paper, the effects of aging on the physicochemical characteristics, the content of microorganisms, molds, acrylamide, heavy metal concentration, and total nutrient content in waste sludge treated with e-beam and gamma irradiation were investigated.

[Euthanasia through history and religion].

INTRODUCTION Euthanasia represents an ethical, social, legal and medical issue, which is being disputed more and more frequently worldwide. In Serbia, it is illegal and punishable by law and subject to a prison sentence. Euthanasia verbatim, meaning "good death", refers to the practice of ending a life in order to relieve pain and suffering.

[Analysis of incidence and treatment of pneumothorax in five-year period in Kragujevac].

Introduction: Pneumothorax is a common clinical problem in thoracic surgery. Leading professional associations have adopted a number of guidelines and recommendations for the treatment of pneumothorax, but their clinical use is often insufficient. This study was aimed at analyzing the incidence of pneumothorax, profile of patients and surgical treatment of pneumothorax at the Clinical Center Kragujevac, in a five-year period.

[Dr James Lovelock and story about GAIA hypothesis].

Introduction: Gaia is the Anglo-Saxon term for the Hellenic term Gea or Ge, which means Earth. The GAIA hypothesis was launched almost 40 years ago by the famous chemist James Lovelock, who was engaged by the National Aeronautics and Space Administration (NASA) to create a sensitive instrument for searching forms of extraterrestrial life on other planets. Then he published the book The ages of GAIA, which perturbed the world's scientific public of those days.

The impact of halo-gravity traction on curve rigidity and pulmonary function in the treatment of severe and rigid scoliosis and kyphoscoliosis: a clinical study and narrative review of the literature.

Introduction: The treatment of rigid and severe scoliosis and kyphoscoliosis is a surgical challenge. Presurgical halo-gravity traction (HGT) achieves an increase in curve flexibility, a reduction in neurologic risks through gradual traction on a chronically tethered cord and an improvement in preoperative pulmonary function. However, little is known with respect to the ideal indications for HGT, its appropriate duration, or its efficacy in the treatment of rigid deformities.
