In this paper, we propose a new compact quasi-fractal shaped microstrip antenna that consists of a hexagonal patch as the main radiator and a complementary stacked patch as the parasitic element. The overall surface of the proposed quasi-fractal patch is about 55% lower than the conventional hexagonal patch. Using of stacked technique, the gain reduction of compression technique is almost compe...

Image analysis is an image processing technique that aims to extract features or information from images. Image analysis in medicine has a special place because is a basis for disease diagnosis for physicians. Electrophoresis is a laboratory separating technique. Electrophoresis images are created during the electrophoresis process. Serum protein and hemoglobin electrophoresis test are the ...

Advances in sarcoma treatment are largely based on investigator-initiated, multicentric and interdisciplinary clinical trials. The EU’s Good Clinical Practice Directive 2001/20/EC, effective since 2004, was meant to harmonize the conditions for clinical trials across Europe, but, instead, the challenge of initiating and running multinational, noncommercial clinical trials has become greater tha...

Article 4 of Council Directive 81/851/EEC requires that a Member State shall not authorise the placing on the market of a veterinary medicinal product intended for administration to food producing animals [...] unless the active substance [...] contained in the product: a) were authorised for use in other veterinary medicinal products in the Member State concerned on the day of entry into force...

Subsidies have become increasingly important tools of industrial policy due to the gradual liberalization of trade and finance since the 1960s. Still, there is considerable variation in subsidy levels in industrialized countries. In this paper, I seek to explain the variation in the levels of industrial subsidies among OECD countries in the period 1989-1995. I test the impact of both domestic p...

In 2014, at latest in 2015, extensive changes in the legal environment for patents in Europe are to be expected, having considerable impact on monopolizing inventions e.g. from the nanotechnology environment: With establishing the "European patent with unitary effect”, for the very first time the grant of single patents with uniform coverage of (almost) the entire territory of the European Unio...

European Institutions, especially the European Parliament, are venues of access for digital activist networks wishing to influence policymaking on issues of intellectual property rights, internet regulation and the respect of civil rights in digital environments. We refer to these networks as “digital activism”. They are more or less loosely rooted in hacker culture and are intensively making u...

The transient response of passivated metallic electrode system under potential step was analyzed based on a linear model, and a technique for calculating the parameters characterizing the growth and dissolution of passive film was proposed. It is believed that the information which is expected to be gained from the impedance measurement can be obtained by this technique and that this technique ...

projects execution is an important way to implement organizational strategies, especially in the project-based organizations. in such organizations, the decision-makers usually encounter a problem of the project portfolio selection. of course, regarding the decision-makers’ risk attitude, they tend to direct organizational resources toward projects with low threats and high opportunities. this ...

this paper proposes a new smart antenna beamforming scheme based on electronically steerable parasitic array radiator (espar). the proposed method is capable of providing better capacity compared to the conventional espar. the termination of each antenna element in this structure comprises a pin diode in addition to a varactor. using pin diode besides the varactor provides more degrees of freed...
