2. A High-Gain Hemispherical Dielectric Lens Antenna Operating Simultaneously in Narrowband or Wideband for X-band Applications
Abstract A hemispherical dielectric lens antenna is proposed to provide beam-steering for communication networks operating in X-band. Two different printed antennas are simultaneously used to guarantee high performance and diversity of applications, one a wideband linear polarized antenna, and the other a narrowband circular polarized antenna. To ensure this

3. Pediatric population with cystic fibrosis in the centre of Portugal: candidates for new therapies
Abstract Objectives: Cystic fibrosis (CF) is a severe autosomal recessive disease that results from mutations in a gene encoding the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) protein, a chloride channel. This study aims to characterize the clinical and genetic features of a cohort of pediatric people with CF (PwCF) in the center of Portugal

4. Effect of different diet pellet sizes on the growth of juvenile cobia (Rachycentron canadum)
RESUMO A relação entre o tamanho do pellet da ração e o crescimento dos peixes é bem conhecida na literatura. No entanto, a magnitude dessa associação em relação à eficiência alimentar dos animais ainda não está clara. Portanto, o presente estudo conduzido na Universidade de Virginia Tech (Virginia Seafood Agricultural Research and Extension Cen

5. Anesthesiologists’ perception on their residency training
Abstract Background: Self-regulated professions such as medicine are characterized by professional commitment to the public they serve and require life-long development of expected skills. There is a paucity of data regarding quality of training during residency in anesthesiology. The objective of this study was to create an instrument to assess the anesthe

6. A Straightforward Synthesis of Enantiopure (1S,2R)-Ephenamine
An enantioselective six-step synthesis of (1S,2R)-ephenamine starting from readily available chiral amino acid is disclosed presenting 26% overall yield and high optical purity. The use of chiral phenylglycine as starting material was also studied and did not present satisfactory results due to a very sensitive a-carbonyl/benzylic stereogenic center that, in

7. Effect of high petroleum coke additions on metallurgical coke quality and optical texture
Abstract The objective of the present study was to evaluate the effect of high additions of petroleum coke on the rheological properties of coking coal and the quality of cokes produced on pilot scale at the Usiminas R&D Center. For this purpose, blends using petroleum coke additions of 5%, 10%, 20%, 30% and 40% were produced. The results showed that the ble

8. Use of 2,4-D in Mixture with Ethephon and Calcium Carbide in Pineapple Crop
RESUMO: O ácido 2-cloroetilfosfônico (ethephon) e o carbureto de cálcio são usados para induzir e sincronizar a floração da cultura do abacaxi. Alguns produtores têm utilizado, em associação com esses indutores do florescimento, o herbicida 2,4-D. Essa prática baseia-se na hipótese de que o 2,4-D atua como regulador de crescimento, aumentando o ta

9. [PROVISIONAL] Resistance mutations of NS3 and NS5b in treatment-naïve patients infected with Hepatitis C virus in Santa Catarina and Rio Grande do Sul States, Brazil
Abstract Hepatitis C virus (HCV) infection is a worldwide health problem. Nowadays, direct-acting antiviral agents (DAAs) are the main treatment; however, the high level of variability of HCV lead to development of resistance-associated variants (RAVs). Thus, look into the RAVs among infected patients is an important tool for monitoring the efficacy of the t

11. Study of major genetic factors involved in pituitary tumorigenesis and their impact on clinical and biological characteristics of sporadic somatotropinomas and non-functioning pituitary adenomas
Genetic and functional aberrations of guanine nucleotide-binding protein, alpha stimulating (GNAS), aryl hydrocarbon receptor interacting protein (AIP), and pituitary tumor transforming gene (PTTG) are among the most prominent events in pituitary tumorigenesis. A cohort of Brazilian patients with somatotropinomas (n=41) and non-functioning pituitary adenomas

12. Rankl expression predicts poor prognosis in gastric cancer patients: results from a retrospective and single-center analysis
The receptor activator of nuclear factor κB ligand (RANKL)/RANK pathway plays an important role in the prognosis of several solid tumor types, but its role in gastric cancer prognosis has been poorly characterized. A total of 116 gastric cancer patients who underwent surgical resection were enrolled in this study. Expressions of RANKL and RANK in gastric ca
