1. A Design of a Compact Microwave Diplexer in Microstrip Technology Based on Bandpass Filters Using Stepped Impedance Resonator
Abstract This paper describes the design of a compact microstrip microwave diplexer based on bandpass filters and a stepped impedance resonator for 4G applications. The diplexer is composed of two band-pass filters (BPF) that operate at 1.8 and 2.5 GHz. Both bandpass filters for the receiver at 1.705-1.895 GHZ and the transmitter at 2.41-2.6 GHZ have a -3dB

2. COVID-19 pandemic and social distancing: economic, psychological, family, and technological effects
Abstract Introduction The concept of social isolation is currently understood as a measure of epidemiological containment that aims to reduce the speed of spread of the disease, enabling health services to prepare their resources to cope with the likely increase in demand, while also seeking to provide additional protection to groups considered to be at hig

3. Application and comparison of proteolytic enzyme preparations in technology of protein hydrolyzates
Abstract Protepsin belongs to the class of acid proteinases, containing carboxyl groups in the active center. The preparation cleaves peptide bonds formed by aromatic amino acids (tyrosine, phenylalanine), and does not hydrolize esters and amides. Along with the proteolytic complex, Protepsin contains collagenase, lipase, and other digestive enzymes. The pre

4. Foreign direct investment in developing economies A study on the productivity spillover effects in Latin America
Abstract Purpose The aim of this study was to investigate how the productivity spillover effects of foreign direct investment (FDI) in the Latin American economies are manifested. Specifically, the paper sought to identify the role of foreign presence and government intervention through an industrial policy on total factor productivity in Latin American cou

6. E-learning in Pharmacy Education: what do we know about it?
The increase and flexibilization of e-learning in Brazil has generated concern about the low capacity to ensure the quality of institutions and courses. The objective is to identify the literature on experiences of pharmaceutical e-learning. A scope review was carried out, mapping key concepts and evidence. The selected articles, without period restriction,

7. The isolation of pentose-assimilating yeasts and their xylose fermentation potential
ABSTRACT For the implementation of cellulosic ethanol technology, the maximum use of lignocellulosic materials is important to increase efficiency and to reduce costs. In this context, appropriate use of the pentose released by hemicellulose hydrolysis could improve de economic viability of this process. Since the Saccharomyces cerevisiae is unable to fermen

8. Seismic Performance of Cable-sliding Modular Expansion Joints Subject to Near-fault Ground Motion
AbstractAccording to the research fruits of the diverse damages of bridge in the past, bearings' invalidation is the main reason of the damage of isolated bridges and causes oversized relative displacements between pier and girder. Eventually, it may lead to severe collision of superstructure. It is extremely dangerous when near-fault motion occurs, because

10. Genetics and human rights: Two histories: restoring genetic identity after forced disappearance and identity suppression in Argentina and after compulsory isolation for leprosy in Brazil
Over the past three decades, there has been an accelerated development of genetic technology, leading to its use in human genetic identification for many purposes. Additionally, it has been made explicit that identity is a fundamental human right. A number of historical circumstances have connected these developments. Personal identity is increasingly associ

11. Uma aplicação de redes definidas por software para a gerência de redes de datacenters virtualizados
Cloud-Computing services related to infrastructure have been drawing much attention recently. On this business model, virtualization is an efficient way to ofier flexibility, isolation and several new functionalities. This technology has led to the multi-tenant datacenter model for Cloud-Computing, where the client (tenant) can rent not only a virtual machin

12. Isolation and fusion of protoplasts from the phytopathogenic fungus Sclerotium rolfsii (Sacc.)
Sclerotium rolfsii (Sacc.) is a serious plant pathogenic fungus and lacks perfect (basidial) stage in production. Protoplast fusion technology was employed to reconstruct fusants from this fungus. Two strains designated as A and R were used. Maximum protoplast yields of 3.8x10(5) /g mycelia and 2.8x10(5) /g mycelia were formed in strains A and R respectively
