The authors of the artlcle analyze the problems of legal regulatlon of ratlonal subsoll use and energy consumptlon ln Russla, Germany, USA, Japan and other countrles. It also compares the energy leglslatlon of dlfferent countrles. Based on the results, lt was concluded that the development of the leglslatlon of these countrles ls ln general compllance wlth the strateglc goals ln the fleld of energy productlon and consumptlo

Intracranial Iatrogenic Foreign Bodies: Features of Neuroimaging

The timely diagnosis of postoperative consequences through identification of intracranial foreign bodies enables prevention of complications and improvement in quality of life. The paper considers two clinical cases after surgical interventions to remove subdural and intracerebral hematomas of different ages. Computed tomography (CT) was performed on a 64-slice Somatom Perspective apparatus (Siemens, Germany) applying a reformative slice thickness of less than 0.6 mm. Magnetic resonance imaging (MRI) was carried out using a Magnetom Essenza 1.5 T system (Siemens, Germany). When wording the CT and MRT findings, it was suggested that each of the patients had an intracranial foreign body in the presence of postoperative changes. The CT and MRI findings were fully correlated with intraoperative data on the location, number, shape, and size of foreign bodies. The neuroimaging techniques are highly informative in identifying intracranial foreign bodies and are especially important for chronically critically ill patients because of the lack of productive contact with them due to speech problems and cognitive impairment. They assist in making a correct diagnosis and playing a leading role in neurosurgical practice, allowing the detection of an abnormality, the optimal planning of patient management tactics, and the prevention of possible complications

Neurofibromatosis Type 2 Involving the Brain and Spinal Cord

Neurofibromatosis type 2 is a rare genetic disease that occurs with a frequency of approximately 1 in 50,000 newborns and is characterized by benign tumors, mainly bilateral schwannomas of the VIII cranial nerve. It is inherited by an autosomal dominant type without sex. Clinical symptoms are associated with damage to the VIII pair of cranial nerves, skin manifestations are less common than with neurofibromatosis type 1. The tumor can be one-sided and can be combined with neurofibromas, meningiomas (intracranial and spinal), schwannomas of other cranial nerves, astrocytomas and ependymomas of the spinal cord. In detecting tumors and making a primary diagnosis, the leading role is played by instrumental diagnostic methods: magnetic resonance imaging (MRI) and computed tomography (CT). The final diagnosis is made after genetic analysis. The article presents the possibilities of CT and MRI in imaging and  diagnosis of type neurofibromatosis type 2

Difficulties in the Radiation Diagnosis of Acute Mesenteric Thrombosis in Patients with Chronic Critical Illness

Acute mesenteric ischemia is an acute disruption of blood supply to part of the intestine, which, if untreated, leads to bowel wall necrosis and a patient’s death. Computed tomography (CT) plays a leading role in detecting mesenteric ischemia and in making the initial diagnosis, especially in patients with chronic critical illness, when productive contact is impossible. The final diagnosis is established during surgery or postmortem examination. Timely diagnosis and surgical treatment are a basic tool to reduce high mortality rates from this disease. The article presents the possibilities of CT in imaging and making the primary diagnosis of mesenteric ischemia and mesenteric thrombosis

Some results of full-scale experiments to study the effect of forest fires on atmospheric characteristics

The article presents the results of a series of mesoscale experiments to study wildfires and their impact on the atmosphere. A change in meteorological parameters, a significant increase in fluctuations of the refractive index, speed of sound and temperature in the vicinity of the experiment, which are a reflection of the occurrence of turbulent processes in the atmosphere, were established, experimental data were obtained on changes in the concentration of methane and carbon dioxide as a result of a fire, and data were obtained on the mechanism of occurrence of crown fire
