1. The Harbin Medical University nephrectomy score: a quantitative system for evaluating the complexity of laparoscopic retroperitoneal simple nephrectomy
ABSTRACT Background: Laparoscopic retroperitoneal simple nephrectomy (LRSN) has been widely accepted as a mainstay option for benign non-functioning kidney. The complexity of the procedure, however, differs and remains a subject of controversy. Objective: To develop a standardised Harbin Medical University nephrectomy score (HMUNS) system for evaluating LR

2. Catalytic Transformation Conditions of Ethanol on Dealuminated BEA Zeolites
Catalysis is an important tool in obtaining a range of derivative products from renewable sources, such as ethanol. Solid-state dealumination using ammonium hexafluorosilicate on the BEA zeolite under the treatment at temperature of 190 °C, 70 mol% dealumination in the presence of humidity and washing with buffer solution at 25 °C generated larger pores. T

3. Molecular identification of a cyclodextrin glycosyltransferase-producing microorganism and phylogenetic assessment of enzymatic activities
Abstract: Cyclodextrin glycosyltransferases (CGTases) are important enzymes in the biotechnology field because they catalyze starch conversion into cyclodextrins and linear oligosaccharides, which are used in food, pharmaceutical and cosmetic industries. The CGTases are classified according to their product specificity in α-, β-, α/β- and γ-CGTases. As

4. Unfolding additional massive cutback effects of the Native Vegetation Protection Law on Legal Reserves, Brazil
Resumo: A Lei de Proteção da Vegetação Nativa - 2012 - (LPVN) é a principal lei brasileira para proteção da vegetação nativa (VN) em terras privadas. A LPVN, atualmente em fase de implementação, reduziu os requerimentos de Reserva Legal (RL) presentes no Código Florestal (CF) de 1965 através de uma série de mecanismos legais. Entre eles, o Arti

6. Mejora en la calidad de imágenes ultrasónicas aplicando métodos de composición espacial y empleando sistemas de Phased Array
ABSTRACT The Phased Array Ultrasonic Technique (PAUT) has become a widely used imaging tool for the Nondestructive Testing in the industrial field. The PAUT allows making deflections and focusing the ultrasound beam at different depths within the material, through an electronic control of each one of the N elements that make up the array transducer. Thus, se

7. CHROMATOGRAPHIC INVESTIGATION OF RUTHENIUM NITROSYL COMPLEX: NO INTERCONVERSION AND REACTIONS WITH BIOLOGICAL REDUCTANTS
One experimental strategy to prepare a nitrosyl metal complex is based on the acid-base conversion of NO2- into NO+. Here, we employed UV-vis absorption and FTIR spectroscopies to investigate the reaction of cis-[Ru(NO2)(bpy)2(imN)]PF6 with H3O+, which produced cis-[Ru(NO)(bpy)2(imN)](PF6)3 complex. Chromatographic studies were carried out and showed that im

8. DESAFIOS RELACIONADOS À PRODUÇÃO E APLICAÇÃO DAS ENZIMAS CELULOLÍTICAS NA HIDRÓLISE DA BIOMASSA LIGNOCELULÓSICA
The second generation (2G) ethanol obtained from lignocellulosic biomass has been considered as a potential alternative source of energy for the transportation sector. However, the technologies to convert lignocellulose into fermentable sugars still face several challenges. One of the major challenges of this process is related to the cost of the cellulolyti

9. Estimativa da produção de sedimentos em função da mudança de uso e cobertura do solo
Os processos de mudança de uso e cobertura do solo despertam grande preocupação quanto a se compreender e melhor planejá-los a fim de evitar impactos, como perda da biodiversidade, erosão do solo e contaminação dos recursos hídricos. O trabalho propõe estimar a produção de sedimentos em cenários da microbacia hidrográfica do ribeirão das Guabir

10. Propagação guiada de ondas de VLF: aplicação ao estudo de fenômenos atmosféricos e naturais
Deep amplitude minima are observed in the daily records of Very Low Frequency (VLF, between 3 - 30 kHz) wave amplitudes. Amplitude minima are attributed to modal interference and modal conversion of waves propagating in the Earth - Ionosphere waveguide. The time of amplitude minima is related with the localization of the Terminator line and, therefore, is de

11. Comparative evaluation of UV/VIS and HPLC analytical methodologies applied for quantification of flavonoids from leaves of Bauhinia forficata
Spectrophotometric determinations (direct dilution or after acid hydrolysis) of flavonoid content in leaves of Bauhinia forficata Link, Fabaceae, from two different regions from Brazil were compared with contents of kaempferitrin quantified by HPLC analysis. The absence of kaempferitrin peak in one sample denotes the risk of LC-method failure. On the other h

12. Saccharomyces Cerevisiae cell wall dietary supplementation on the performance and intestinal mucosa development and integrity of broiler chickens vaccinated against coccidiosis
This study was carried out to verify if Saccharomyces cerevisiae cell wall (SCCW) dietary supplementation (0.2%) was capable of protecting the intestinal mucosa of broiler chickens vaccinated against coccidiosis. Body weight gain, feed intake, feed conversion and intestinal mucosa morphometric parameters and epithelial loss were evaluated. In the experiment,
