Aspects of Regional Geothermal Water Use in Bulgaria
ABSTRACT Geothermal water in Bulgaria has only direct applications. Major types of direct utilization include balneology, space heating and air-conditioning, geothermal heat pumps, direct thermal water supply, greenhouses, and bottling of potable water and soft drinks. Electricity generation from geothermal water is not currently available in the country
Radical Cystectomy and Orthotopic Bladder Substitution Using Ileum
Over the past decade, continent urinary diversion, especially orthotopic bladder substitutions, has become increasingly popular following radical cystectomy for bladder cancer. The ultimate goal of orthotopic bladder substitution is to offer patients the best quality of life, similar to that of patients with native bladders. To achieve that purpose, surgeons should be familiar with the characteristics of good candidates for neobladders, the possible intraoperative and postoperative problems related to the surgery, and the solutions to these problems. Postoperative surveillance and instructions given to the patients also contribute to successful, functional results. Here, we reviewed the indications, pitfalls, and solutions for orthotopic bladder substitutions and the patients' quality of life after surgery. When performed properly, orthotopic continent diversion offers good quality of life with few long-term complications. Therefore, we believe it is the best option for the majority of patients requiring cystectomy
Characterization of the Karst water regime in the Danube catchment area (Bulgaria)
The purpose of study is to estimate the role of karst springs in the
formation of the flow of the Bulgarian rivers that are right tributaries of
the Danube River. The study area includes the region from the Danube River to
the main ridge of the Balkan (Stara Planina), representing a major water
divide that separates the Black Sea catchment area from the Aegean one. The
eastern border represents the watershed between the Danube and the Black Sea
hydrological zones. From a geological point of view, the northern part of the
area is located on the Moesian platform and the southern part belongs to the
Fore Balkan and Balkan areas where various types of rocks of different
geologic age outcrop. In some of them, there are conditions for the formation
of karst water. In the northern part of the area they form distinct aquifers
that gradually sink to the north; this is so called "platform" type of karst.
In the southern mountainous part there are numerous karst basins. The most
significant of karst springs are included in the national groundwater
monitoring network. The hydrographs of karst springs are analyzed in view of
the specific features of karstification. To classify the studied springs with
respect to their regime, several indicators are used. Furthermore, the role
of karst waters in the river runoff of the Bulgarian tributaries of the
Danube River is assessed
