The main objective of the paper was to determine the significance of particular methods of supporting women's entrepreneurship in Greater Poland. Five groups of such support have been identified: socio-cultural, promotional and informational, financial, institutional, consulting and training. This led to identifying gaps in existing support and to finding the most significant support for entrepreneurial women. The study revealed a discrepancy between the assessment carried out by experts, students and women entrepreneurs. Owners of enterprises’ opinions show that the available forms of support are not as useful as it might seem from the perspective of researchers and potential owners. There are also forms of support that are not used by the female owners.

Solar energy, since it is available every day, is seen as one of the most valuable renewable energy resources. Thus, the energy of sun should be efficiently used in various applications. The most known applications that use solar energy are heating water and spaces. High efficiency solar collectors need appropriate selective surfaces to absorb the heat. Selective surfaces (Selektif-Sera) used in this study are applied to flat collectors, which are produced by a roll to roll cost effective coating of nano nickel layers, developed in Selektif Teknoloji Co. Inc. Efficiency of flat collectors using Selektif-Sera absorbers are calculated in collaboration with Institute for Solar Technik Rapperswil, Switzerland. The main cause of high energy consumption in industry is mostly caused from low temperature level processes. There is considerable effort in research to minimize the energy use by renewable energy sources such as solar energy. A feasibility study will be presented to obtain the potential of solar thermal energy utilization in the textile industry using these solar collectors. For the feasibility calculations presented in this study, textile dyeing and finishing factory located at Kahramanmaras is selected since the geographic location was an important factor. Kahramanmaras is located in the south east part of Turkey thus has a great potential to have solar illumination much longer. It was observed that, the collector area is limited by the available area in the factory, thus a hybrid heating generating system (lignite/solar thermal) was preferred in the calculations of this study to be more realistic. During the feasibility work, the calculations took into account the preheating process, where well waters heated from 15 °C to 30-40 °C by using the hot waters in heat exchangers. Then the preheated water was heated again by high efficiency solar collectors. Economic comparison between the lignite use and solar thermal collector use was provided to determine the optimal system that can be used efficiently. The optimum design of solar thermal systems was studied depending on the optimum collector area. It was found that the solar thermal system is more economic and efficient than the merely lignite use. Return on investment time is calculated as 5.15 years. {"references": ["http://www.aee-intec.at/0uploads/dateien561.pdf, Accessed on 18/05/2016.", "http://www.solarthermalworld.org/sites/gstec/files/SoPro_Leaflet_en.pdfAccessed on 18/05/2016.", "Kalogirou S. \"The potential of solar industrial process heat applications\", Applied Energy, 2003, vol. 76, no. 4, pp. 337-361.", "S Mekhilef, R Saidur, A Safari, \"A review on solar energy use in industries\", Renewable and Sustainable Energy, 2011, vol. 15, no. 4 pp. 1777-1790.", "Taibi, E, Gielen D, Bazilian M. \"Measuring energy poverty: Focusing on what matters\", Renewable and Sustainable Energy, 2012, vol.16, no.1, pp. 735-744", "Faninger, G., \"The potential of Solar Heat in the future energy system\", IFF-University of Klagenfurt, Austria; www.uni-klu.ac.at/iff/ikn/downloads/Potential_of_Solar_Heat.pdf, Accessed on 18/05/2016", "Vannoni, C., Battisti, R., Drigo, S., Potential for Solar Heat in Industrial Processes, Task 33, 2008.

Diversos autores han establecido la gran importancia que tiene para las empresas el contar con información precisa relativa al costo de cada producto, siendo esto particularmente cierto en el ambiente de la intensa competencia global actual. A pesar de ello, se ha demostrado que los sistemas tradicionales no satisfacen las presentes demandas empresariales por lo que en los últimos años se han propuesto nuevos métodos de costeo los cuales, sin embargo, aún resultan imprecisos. Es por esta situación manifiesta que en este trabajo se presenta una nueva metodología para la determinación del costo de almacenaje de un producto, extrapolable a todos los eslabones de la Cadena de Suministro. A su vez, se propone un nuevo inductor de costo, el índice logístico, el cual contribuye a brindar información más precisa que los métodos tradicionales. Se concluye mostrando un caso de negocio donde se aplica este modelo en una empresa logística española.

They are miniaturized leadless implants without battery placed directly in right ventricle. Amongst different acceptable energy sources in cardiac environment, we choose the solution of a device based on conversion of the energy produced by pressure variation inside the heart into electrical energy. The proposed energy harvesters can meet the power requirements of pacemakers, and can be a good solution to solve the problem of regular surgical operation. With further development, proposed device should provide enough energy to allow pacemakers autonomy, and could be good candidate for next pacemaker generation.

Energy router is an intelligent power electronic device that can realize the active management of power flow and provide convenient access to distributed energy resource. This paper presents the structure of an AC-DC hybrid multi-port energy router, which acts as the interface between the power consumer and the distribution network. The corresponding coordinated control strategy is developed to guarantee the regular operation of the energy router and a mode switch strategy with advanced compensation is proposed to achieve seamless transition between grid-connected mode and islanded mode. A novel and practical fuzzy logic controller considering unit-time electricity charge is proposed for the energy router to prolong battery life, to improve economic benefits of power consumers, and to smooth fluctuations of renewable energy generation or load consumption. The simulation and experimental results have validated the coordinated control and energy management strategies and demonstrated that the energy router has satisfactory performance.

It is well known, that the electrical energy storage in the large scale is basically a difficult process. Such a process is connected with energy losses, as most frequently it is the conversion of electrical energy into another form, for example mechanical, and then back to the primal electrical form. Though, the SMES technology offers the energy storage in an unchanged form, which is advantageous primarily in the achieved efficiency. The magnetic resonance imaging (MRI) devices, commonly used in the medical facilities are based on the basis of superconducting magnet. After its rejection from operation, (basically caused only by its „software fustiness“ and not by functional faults), there is a possibility of using such devices for the energy storage purposes. Additionally, such a technology of storage is also ecological. A research project is running at the Faculty of Mining, Ecology, Process Control and Geotechnologies (F BERG), the Department of Business and Management, in the field of using rejected MRI for energy storage purposes.
