13. A 2.4 GHz Coplanar Solar Cell Patch Antenna with a Semi-Analytical Evaluation of Temperature Effects
Abstract Solar cells integrated with antennas have aroused scientific interest as an attractive energy source alternative in low power devices for IoT and Wireless Sensor Network applications. Since the space for all components in the systems is scarce, different integration ideas have been proposed in this field. However, further analysis of the performance

14. The power to tolerate
Resumen: La tolerancia es un privilegio de los poderosos. Una persona puede tolerar sólo si tiene el poder para interferir con aquello que objeta. En este artículo analizaré las circunstancias en las que alguien tiene el poder para tolerar. Argumentaré que la respuesta debe incorporar consideraciones tanto prácticas como metafísicas. Específicamente,

15. Broadband Antennas Based on the Double Moebius Strip
Abstract The family of new antenna designs based on the double Moebius strip principle is proposed in this article. Three possible options of the power supply port location had been reviewed in this respect: the cut external strip with the signal port located directly in the cut area is used; the continuous rings without discontinuities are applied, with the

17. Validation of the Grace Risk Score to Predict In-Hospital and 6-Month Post-Discharge Mortality in Patients with Acute Coronary Syndrome
Abstract Background The wide range of clinical presentations of acute coronary syndrome (ACS) makes it indispensible to use tools for risk stratification and for appropriate risks management; thus, the use of prognosis scores is recommended in the immediat clinical decision-making. Objective To validate the Global Registry of Acute Coronary Events (GRACE

18. Left Ventricular Assist Device Thrombosis: Combined Approach by Echocardiography and Logfiles Review for Diagnosis and Management
ABSTRACT Introduction: Left ventricular assist devices are an established therapy for end-stage heart failure. Follow-up of these patients showed complications, such as thrombosis. Our objective was to evaluate the contribution of echocardiography — in association with HeartWare HVAD online logfiles reviews and lactate dehydrogenase titration — for diag

19. 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

20. 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

22. 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

23. REPLY TO “REFLEXIVITY, ROLE CONFLICTS, AND THE MEANING OF ENGLISH SELF PRONOUNS”
Abstract Stern’s Columbia School Theory contribution on English self-pronouns provides a wonderful illustration of the explanatory power of an approach that refuses to be taken in by a priori grammatical categories like reflexivity, which have the unfortunate consequence of giving the analyst the impression that he or she already knows all about the semant

24. Enhanced Catalytic Performance of Strontium-Doped Lanthanum Manganites by the Presence of Molybdenum Oxides for Electro-Reduction of Hydrogen Peroxide
In this work, two catalysts, lanthanum manganite strontium-doped perovskite without (LSM) and with (LSMMO) mixed molybdenum oxides, were synthesized by the sol-gel route and deposited by immersion in carbon cloth substrates. Their performance as cathodes in the hydrogen peroxide reduction reaction (HPRR) and oxygen reduction reaction (ORR) was investigated t
