1. Single-Layered Paper-Based Microfluidic Devices Made by Paint-Spraying Technique with Great Barrier Resistance for Colorimetric Assays
The single-layered paint-spraying paper based microfluidic devices (sp-μPADs) have been for the first time integrated with the colorimetric assay. The polymethyl methacrylate (PMMA) board was applied as the mask instead of the iron mask, reducing the power requirement of the cutting machine. The paint was sprayed into the paper, which blocked the pores of t

2. Conflictos en la frontera, los derechos y las políticas de un pacto social
Abstract The conflicts of the borders between nations and the social pacts establish interactions between social agents, rights and the democratic State. The objective of the article is to analyze, from the sociological point of view, the relationship between the perception of the existence of social pacts and the multiple conflicts. We investigated the nort

3. Integrated Guidance and Control of Multiple Interceptor Missiles Based on Improved Distributed Cooperative Control Strategy
ABSTRACT In this study, an improved cooperative integrated guidance and control (IGC) design method is proposed based on distributed networks to address the guidance and control problem of multiple interceptor missiles. An IGC model for a leading interceptor is constructed based on the relative kinematic relations between missiles and a target and the kinema

4. Kidney injury and other complications related to colonoscopy in inpatients at a tertiary teaching hospital
OBJECTIVES: To describe clinical complications related to colonoscopy in inpatients with multiple diseases. Among the known complications, acute kidney injury was the primary focus. METHODS: This was an observational retrospective study of 97 inpatients. Data relating to age; gender; comorbidities; current medication; blood tests (renal function, blood glu

5. An unusual presentation of urethral duplication presenting with chronic bladder retention, left scrotal transposition and left renal agenesis
ABSTRACT Introduction and objective Urethral duplication is a rare congenital anomaly, with roughly 200 cases reported in the literature (1). It is more frequent in males, with few cases reported in females. The clinical presentation differs according to the anatomical variant present. The duplication most commonly occurs in the sagittal plane with one uret

6. Dislocation Density and Texture in Copper Deformed by Cold Rolling and Ecap
Analysis of dislocation density in metallic materials has been pursued with great interest for many years because dislocations are closely associated with plastic deformation and thus exert a deep effect on the mechanical properties of any material. Crystallographic texture has also a decisive influence in some properties. In this work, the dislocation densi

7. Experimental Evaluation of the Mobile Radio Channel Capacity in the 2.48 GHz Band
Abstract This paper deals with the effect of the Single-Input Multiple-Output spatial diversity on the OFDM mobile radio signal propagating in an urban channel. From measurements performed in Rio de Janeiro city, Brazil, by using two receiving antennas at diversity, the calculated capacity presented an improvement when compared to the individual one.

8. CFD 2D Description of Local Flow of Polymer Workpiece through a modified U-Shaped Die During Equal Channel Multiple Angular Extrusion
The present article is focused on a 2D computational fluid mechanics study of local viscous flow dynamics and the formation character of rotary modes of deformation during Equal Channel Multiple Angular Extrusion (ECMAE) of a polymer workpiece fluid model through a U-shaped die with parallel slants in channel intersection zones. The present local flow proble

9. Dislocation Density by X-ray Diffraction in α Brass Deformed by Rolling and ECAE
Dislocations are responsible for most aspects of plastic deformation in metals. In this work, the dislocation density, ρ, in brass was estimated after different deformation processes via line broadening of X-ray diffractograms using the Convolutional Multiple Whole Profile Program (CMWP) and by Transmission Electron Microscopy (TEM). In addition, we attempt

10. Withdraw of the Ureteroscope Causes Fragmented Ureter Stones to Disperse
Introduction Ureteroscopy has improved from the first use of ureteroscope in the 1970's. Although the success rate increased in the last years, (1) new treatment techniques are being developed for impacted and large proximal ureter stones (2). Pneumatic lithotripsy has high efficiency with low complication rates (2). However, in case of steinstrasse and lar

11. Orçamento participativo: os limites da inovação institucional em Cuiabá-MT / Participative budget: the limits of institutional innovation in Cuiabá-MT/Brazil
The democratization process in Brazil in recent decades resulted from the combination of different forms of collective mobilization and changes in the state apparatus. The end of authoritarianism and democracy openness produced new sociopolitical arrangements of popular participation and enhancement of citizenship, through of creation of inclusive mechanisms

12. VHDL SIMPLE SYSTEM FOR DEVELOPING A SETUP OFMULTIPLE ANTENNAS / SISTEMA SIMPLES EM VHDL PARA O DESENVOLVIMENTO DE UM SETUP DE MÚLTIPLAS ANTENAS
MIMO systems (Multiple In - Multiple Out) are the rise of new tele- communication systems. They have the characteristic of generating greater channel capacity with low power transmitters, creating a more efficient use of energy. As the purpose is to provide higher data rate, conventional methods are too limited to improve this, and MIMO systems generate an i
