1. Selecting alternative sterile and non-sterile substrates for mycorrhizal inoculant production
ABSTRACT Alternative substrates were evaluated for mycorrhizal inoculants production considering the beneficial effects of arbuscular mycorrhizal fungi (AMF) for plants and environment. The first step of the experiment aimed at evaluating the potential of substrates produced from sugarcane bagasse (SB), coconut fibre (CF) and urban waste compost (UWC) to pro

2. Revised formula for predicting the long-term deflection multiplier of normal and high strength concrete
Abstract High strength concrete (HSC) has found many applications in civil engineering structures such as in high-rise buildings, and bridges. The mechanical properties of HSC are sometimes different than of normal strength concrete (NSC). In particular, HSC possess lower creep strains compared to NSC. As a result, members constructed using HSC have been fou

4. Low cost system to measure active power in electrosurgical units
Abstract Introduction: The real-time measurement of active power delivered to patients during the electrosurgical act is still an engineering challenge. Besides, there is no electrosurgical unit on the market capable of doing it according to the normative requirement. Methods This work presents the design of an electronic structure capable to probe the ele

5. An Analytical Solution for Fiber Optic Links with Photonic-Assisted Millimeter Wave Upconversion Due to MZM Nonlinearities
Abstract Photonic-assisted technique employed in the generation of stable and high-purity signals in the millimeter wave band has been investigated using dual-parallel Mach-Zehnder modulator. Indeed, this type of generation performs a high order RF multiplier, whose operation principle steams out from the nonlinear characteristic of the external modulators.

6. Development of Sliding Connections for Structural Analysis by a Total Lagrangian FEM Formulation
Abstract In this study a total lagrangian 2D finite element formulation is used to model plane frames developing large displacements and rotations considering sliding connections. This kind of connections is usually called prismatic and cylindrical joints. In order to be self-containing, the steps of the development of a frame finite element of any approxima

7. Fiscal multipliers in an incomplete markets economy
This paper studies the behavior of fiscal multipliers in two different economic environments: complete markets and incomplete markets. Based on steady state analysis, output multipliers are found within a range between 0.49 and 0.66, when the markets are complete. Under incomplete markets, output multiplier was found in an interval between 0.75 and 0.94. The

8. Um algoritmo para estimar a dimensão do segundo grupo de homologia de um grupo finitamente apresentado / An Algorithm for low Dimensional Group Homology
O trabalho tem por objetivo principal estabelecer uma cota superior para a dimensão do segundo grupo de homologia de um grupo G, com coeficientes em um corpo k de característica p, H2(G;k), usando o sistema operacional GAP. Será apresentado uma gama de exemplos, onde em alguns casos, calcularemos exatamente a dimensão e em outras somente uma cota superio

9. Framework de sustentabilidade para instituições de ensino superior comunitárias
The concern with sustainable development in organizations, and especially in Higher Education Institutions (HEIs) that have precursor and developing characteristics has stopped being a proactive attitude and has became a premise of its management, teaching and research. The objective of this research is to propose a framework of sustainability facing the con

10. Macrodinâmica à Keynesiana : uma travessia com consistência entre fluxos e estoques a partir do encadeamento de curtos períodos do multiplicador / Keynesian-style macrodinamics : a stock-flow consistent traverse throught the enchainment of short multiplier periods
This thesis is divided into three parts. The first one discusses the short period behind the traditional autonomous expenditure multiplier, in a way that exposes the major macroeconomic aggregates and their interconnections; at this point the separation between the autonomous and induced parcels with respect to income is crucial. A second chapter, compoundin

11. Two-phase experimental heat transfer studies on a water-diesel system in a shell and tube heat exchanger
Two-phase heat transfer involving two immiscible systems is gaining importance in petrochemical and allied industries. Varying compositions of diesel and water were experimentally studied in a 1:2 shell and tube heat exchanger. The data on pure water and diesel were fitted to an equation of the form. h1φ = a NmRe.The two-phase multiplier, Φ L, was related

12. Uso de parâmetros multifractais no reconhecimento de locutor / Use of multifractal parameters for speaker recognition
Esta dissertação apresenta a implementação de um sistema de Reconhecimento Automático de Locutor (ASR). Este sistema emprega um novo parâmetro de características de locutor baseado no modelo multifractal "VVGM" (Variable Variance Gaussian Multiplier). A metodologia adotada para o desenvolvimento deste sistema foi formulada em duas etapas. Inicialmente
