Sentinel-2 water indexes application for the underground water level analyses in Ovidiopol area of Odessa region
Studied area has a high level of agricultural development. There are different irrigation and drainage systems located there. Significant part of the supplied water losses from the irrigation network because of filtration and reaches the groundwater level, which begins to rise. Control and analyses of groundwater level changes with remote sensing methods for Ovidiopol area is the main goal of that work. The object of study is the groundwater level regime in the territory of Lower Dniester irrigation system in Ovidiopol district, Odessa region. The subject of research is water indexes application for analyses of groundwater level changes. The local system of groundwater observation includes 7 drillholes in Nadlimanskoe village and around. These drillholes located in different geomorphological, hydrogeological and technogenic conditions. The groundwater level was surveyed monthly in 2017. Sentinel-2 2A images for each month from March 2017 to December 2017 were used for studied area. All satellite images has atmospheric correction. Three water indexes NDWI, MNDWI, NDPI were calculated for drillhole points for each month in 2017 year. Significant correlation coefficients obtained in comparison between groundwater level changes and water indexes in some drillholes points. The highest numbers of correlation connected with free of construction areas and for drillholes, which are located outside of villages

Resection interventions in the treatment of hepatocellular cancer in a specialized surgery center
Background. The relevance of the treatment of hepatocellular cancer (HCC) is determined by a significant increase in the incidence rate and its high prevalence among primary malignant hepatic tumors.The aim of the study. To summarize the experience of providing specialized medical care to patients with hepatocellular cancer.Methods. We studied the direct results of treatment of patients with primary hepatic cancer treated at the Kuzbass Regional Hepatological Center for the period from January 2015 to August 2022. The materials for the study were medical records of patients with an established diagnosis of primary hepatic cancer, surgical records, results of pathohistologic examination. The exclusion criterion was diagnosed cholangiocellular carcinoma.Results. During the period from 2015 to 2022, 59 patients with primary hepatic cancer were treated at the Kuzbass Regional Hepatological Center. Among them, hepatocellular cancer was diagnosed in 48 cases, cholangiocellular cancer β in 11 cases; radical surgery was performed in 12 patients with hepatocellular cancer; fatal outcome was noted in 1 (2.1 %) patient, complications in the postoperative period developed in 5 (41.7 %) cases and were ranked as I-3, IIIb-1 and IVb-1 according to Clavien β Dindo classification.Conclusion. The degree of risk of severe post-resection hepatic failure should be considered one of the main criteria in choosing a strategy for radical surgical treatment. New surgical approaches (laparoscopic vascular isolation of the portal blood flow, using temporary hemostasis in laparoscopic hepatic resections and the device for its implementation) in resection surgery of primary hepatic cancer can improve the immediate results of treatment
Poloidal inhomogeneity of the particle fluctuation induced fluxes near of the LCFS at lower hybrid heating and improved confinement transition at the FT-2 tokamak
This paper deals with the new spectral and microturbulence experimental data
and their analysis, which show, that the radial electric field Er generated at
the LH heating (LHH) in the FT-2 is high enough to form the transport barriers.
The ETB is formed when LHH is switched off. The radial fluctuation-induced
EB drift flux densities near LCFS in SOL are measured at two different
poloidal angles. For this purpose two Langmuir probes located at low and high
field sides of the torus are used. Registration of the poloidal and radial
components of the electric field and density fluctuations at the same time
during one discharge permits to measure the poloidal asymmetry of the transport
reduction mechanism of the radial and poloidal particle fluxes in the SOL. The
absolute E(~) fluctuation levels show dependence on the sign of Er
shear. The modification of the microscale turbulence by the poloidal Er x B
rotation shear EB at the L - H transition near LCFS is also
studied by X-mode fluctuation Reflectometry. The new data were obtained by
spatial spectroscopic technique.Comment: 12th International Congress on Plasma Physics, 25-29 October 2004,

Acute cerebellar ataxia in a young woman: Wernickeβs encephalopathy?
Wernickeβs encephalopathy (WE) is a rare but severe neurological syndrome caused by thiamine deficiency. According to the data of autopsy studies, the prevalence of WE in the general population varies from 0.4 to 2.8 per 100,000 population; the disease occurs many times more frequently in alcohol abusers than in people who lead a healthy lifestyle. These studies also showed that most cases of WE were diagnosed postmortem; less than 20% of patients with the disease were diagnosed in life. A healthy adult requires 1β2 mg of thiamine daily, depending on the carbohydrate intake. Bodyβs reserves of thiamine are only 30β50 mg so any malnutrition condition lasting more than 3β4 weeks can cause complete depletion of the vitaminβs stores. Classically, WE is characterized by the sudden onset of a typical triad of symptoms: an altered mental state, ophthalmoplegia, and ataxia. However, this clinical picture can be seen in only one-third of patients. The onset of the disease may sometimes look completely different: heart failure with hypotension and tachycardia; gastrointestinal symptoms (abdominal pain and nausea); hypothermia due to the involvement of the posterior hypothalamus; deafness affecting the thalamus; epileptic seizures in case of enhanced activity of the glutamatergic system.The paper describes a clinical case of acute cerebellar ataxia that is apparently caused by Wernickeβs encephalopathy in a young woman
