This paper reports our experience in the development of an interdisciplinary curriculum at the point of intersection between investment management in telecommunications for a joint MSc degree and the evaluation of the curriculum. Lecturers and professors from three faculties of Plovdiv University participated in development of the “Investment Management in Telecommunications” (IMT) Master progr...

This article clarifies the requirements of VHE (Virtual Home Environment), issues and resolution for realization of VHE, when the environment will use Intelligent Network (IN) within IMT-2000 networks that is targeted to start in the year 2000. The IN aims the applicability of it’s architecture to any kind of network. However, the following subjects need to be considered when IN will be used in...

Intensive vegetable cropping systems use large amounts of water and nutrients. Excess application of water and nutrients results in economic losses (higher fertilizers and pumping costs) and contributes to nutrient leaching and environmental degradation. Increasing nutrient use efficiency (NUE) and water use efficiency (WUE) should be a priority for sustainable horticulture. This increased NUE,...

A proposal for energy management in an off-grid photovoltaic pumping and irrigation system is presented and evaluated for a specific case study. The system is assumed to be based on off-the-shelf components (photovoltaic panels, battery banks, DC/AC converters, relays, submergible pumps, etc.), with a microcontroller-based energy management system, deciding when to disconnect the load from the ...

An inflammatory myofibroblastic tumor (IMT) is an uncommon, benign lesion characterized by the mesenchymal proliferation and infiltration of inflammatory cells composed primarily of lymphocytes and plasma cells. A percutaneous radiofrequency ablation (RFA) is an effective and safe therapeutic modality used for the management of liver malignancies. Here we report, for the first time, a case of I...

Despite of the water use increment for other sectors than agriculture, the water use for irrigation is the main water consumer in global scale. However, irrigation has been pressured by the civil society to improve water use efficiency in agriculture, to prevent water scarcity for human population that grows continuously, mainly in developing areas of the planet. On the other hand, the irrigati...

BACKGROUND Tissue factor pathway inhibitor (TFPI) is a physiological antagonist of TF. We tested whether a brief irrigation with TFPI protein (rTFPI) or TFPI gene transfer into injured arteries would suppress TF activity and reduce fibroproliferative changes and investigated whether a combination of these methods would show an additive effect. METHODS AND RESULTS We prepared adenoviruses expr...

Many water management problems have arisen in past Asian irrigation projects. They have been characterized as a vicious cycle involving the lack of maintenance, poor irrigation service, low rates of fee collection, inadequate institutional arrangements, and lack of user participation. This article argues that we have generally agreed on a strategy to address these problems and asks whether or n...
