25. Microstrip 3-Bit Fractal-based Phase Shifter
Abstract This paper presents the implementation of a 3-bit microstrip fractal-based phase shifter operating in the 430 MHz to 470 MHz frequency range. The fractal structure is used to confine different delay line lengths in the same area due to the space-filling properties of the used Hilbert fractal curve. The proposed design has three bits corresponding to

26. Formation of a new rural power structure and the failure of gender in utopia: lesbian image and its metaphors in Wildcat Lake
Resumo: Chen Yingsong criou Lago Gato Selvagem não apenas para contar uma história sobre lésbicas. Ao descrever como Xiang’er, uma mulher rural, torna-se lésbica nas aldeias, pode-se ver a “riqueza” e o “significado metafórico” do símbolo lésbico. No que diz respeito ao Lago Gato Selvagem, é mais interessante tratar como Xiang’er se torna

27. AN INVESTIGATION ON THE ROLE OF REFERENTIALITY IN THE INTERPRETATION OF RELATIVE CLAUSES IN BRAZILIAN PORTUGUESE
Abstract This paper presents an off-line experiment we conducted to investigate the influence of referentiality on relative clause (RC) interpretation in Brazilian Portuguese. RCs associated with complex NPs seem to be preferentially attached to a referential noun. This referentiality effect can be treated in discourse terms (Gilboy, Sopena, Clifton & Frazie

28. Royleanine A, an Antitumor Dihydro-β-agarofuran Sesquiterpene Pyridine Alkaloid from Maytenus royleanus
Genus Maytenus (Celastraceae) has proved to be a good source of new bioactive sesquiterpene pyridine alkaloids. Maytenus royleanus is a medicinal plant used in folk medicine for different ailments in a variety of ways around the world. Investigation of the roots of M. royleanus resulted in the isolation of an undescribed antitumor sesquiterpene pyridine alka

29. A High-Selectivity Bandpass Filter Using Dual-Mode Coupling Resonator
Abstract In this work, a new model of high selectivity dual-mode bandpass filter is presented. The proposed filter consists of a set of coupled lines with a dual-mode adjustable response in its design process. An improvement in selectivity is presented by combining the dual-mode element with a classic band rejection structure, thus making it possible to intr

30. A CAPACITARIAN ACCOUNT OF CULPABILITY FOR NEGLIGENCE
Abstract Ascribing moral and legal responsibility for negligent actions and omissions has always been deeply contested because it seems to be in tension with the natural intuition that responsibility requires control. In this paper I show that we can accommodate culpability for negligence within a control-based account of responsibility if we adopt a “capa

31. Analysis of dielectric and electrical transport properties of NdFeAsO ceramic
Abstract The iron-based ceramic NdFeAsO was synthesized by the solid-state reaction method. The tetragonal crystal structure was confirmed at room temperature through the X-ray diffraction technique. The dielectric characteristics i.e. dielectric constant (εr) and loss tangent (tanδ) of the sample were studied at a wide range of temperature and frequencies

32. Transformations in the Ownership Structure of Credit Unions: Banking Service Rates and the Expectations of Members and Directors
RESUMO Adesões à livre admissão de membros e incorporações são transformações na estrutura de propriedade comuns no cooperativismo de crédito brasileiro. Sob a lógica de que são motivadas pelas expectativas de membros e diretores, este trabalho associou essas transformações às taxas de serviços bancários operacionalizadas pelas cooperativas.

33. Mechanical properties and fractography of cement-based composites reinforced by natural piassava and jute fibers
Abstract Today’s demand for environmentally friendly and energy-efficient solutions to the construction industry has driven researchers to match natural resources with traditional technics to develop new building technologies. However, there are literature limitations about the correlation of fiber-matrix interface with the failure of natural fibers in mor

34. Characterization and potential applications of new boron-phosphate glass in the CaO-P2O5-K2O-B2O3 system
Abstract Boron phosphate glasses are known for their unique properties and have been investigated as biodegradable materials for biomedical applications. In this context, the present research studied the characterization of physical, mechanical, and bioactive properties of new boron-phosphate glass in the CaO-P2O5-K2O-B2O3 system produced by the melt-quenchi

35. Design and Implementation of Microwave Dual-Band Pass Interdigital Filter Using an Analytical Approach
Abstract In this paper, benefiting from frequency transformation between the normalized frequency domain of low-pass prototype frequencies and the real frequency domain of the filter, a purely analytical procedure for dual-band filter design is used. The coupling matrix of the filter is analytically extracted, without the need to perform numerical optimizati
