1. PREPARATION AND SIMULATION OF THE ON-LINE SiO2/S COATING FOR COKING INHIBITION IN THE INDUSTRIAL CRACKING FURNACE
Abstract Coke formation inside radiant coils is one of the main problems during thermal cracking of hydrocarbons. The on-line preparation of the coating for coking inhibition is a promising technology because it provides more flexibility to the operators on site. The SiO2/S coating was prepared on the inner surface of coils in an 8-year-served GK-VI industri

2. Polydatin protects H9c2 cells from hypoxia-induced injury via up-regulating long non-coding RNA DGCR5
Polydatin (PD), a monocrystalline polyphenolic drug mainly found in the roots of Polygonum cuspidatum, has various pharmacological activities. Long non-coding RNAs (lncRNA) DiGeorge syndrome critical region gene 5 (DGCR5) was found to participate in the suppression of multiple cancers. Here, we proposed to study the effect of PD on myocardial infarction (MI)

3. DACT1 Involvement in the Cytoskeletal Arrangement of Cardiomyocytes in Atrial Fibrillation by Regulating Cx43
Abstract Objective: To determine the role of the dishevelled binding antagonist of beta catenin 1 (DACT1) in the cytoskeletal arrangement of cardiomyocytes in atrial fibrillation (AF). Methods: The DACT1 expression and its associations with the degree of fibrosis and β-catenin in valvular disease patients were analyzed by immunohistochemistry and Masson�

4. Ação estatal, negócios e migração inter-regional no Brasil (1935-1951) *
Resumo Este trabalho aborda o aparato econômico e os negócios vinculados à migração no Brasil entre 1935 e 1951. Nesse período, a crise do capitalismo primário-exportador no Brasil e a emergência de um novo padrão de acumulação centrado na industrialização e no mercado interno, implicaram mudanças nas dinâmicas populacionais, que passaram a te

5. Morphophysiology of buffel grass grown under different water supplies in the dry and dry-rainy seasons
RESUMO A carência de informações sobre o crescimento de gramíneas forrageiras em ambiente semiárido, sobretudo sob a perspectiva de irrigação, é um dos entraves para a oferta regular de forragem, assim como para o uso racional da água de irrigação. Diante do exposto, objetivou-se avaliar as trocas gasosas foliares, o fluxo de biomassa e as caracte

6. Moisture in the soil profile with water applications using pulse drip irrigation
RESUMO O bulbo molhado, como resultado da aplicação pontual de água de irrigação, é o volume de solo que tem maior umidade em relação à umidade inicial. Devido ao incremento de umidade no solo, sucessivos eventos de irrigação tendem a formar bulbos molhados e área de acúmulo superficial de água (AASA) maiores. Portanto, objetivou-se avaliar a d

7. Conversion Efficiency of Photosynthetically Active Radiation Into Acacia mearnsii Biomass
ABSTRACT The objective of this experiment was to determine the conversion efficiency of intercepted photosynthetically active radiation into biomass of Acacia mearnsii De Wild. seedlings. A forest species, plastic tubes (90 cm3), and 11 evaluation periods (up to 180 days after emergence) were used in this study. The leaf area index (LAI), total dry biomass (

8. Simultaneous HPLC analysis of crebanine, dicentrine, stephanine and tetrahydropalmatine in Stephania venosa
ABSTRACT Stephania venosa (Blume) Spreng., Menispermaceae, has been traditionally used as tonic drug and treatment of various diseases in South East Asian countries. In order to evaluate the quality and standardization of S. venosa roots, the HPLC method for quantification of the content of major components in S. venosa was developed and validated. The chrom

9. Development and evaluation of an inhalation chamber for in vivo tests
ABSTRACT The bioavailability, toxicity, and therapeutic efficacy of a drug is directly related to its administration route. The pulmonary route can be accessed by inhalation after fumigation, vaporization or nebulization. Thus, pharmacological and toxicological evaluation accessed by an apparatus specifically designed and validated for this type of administr

10. Decline of phosphorus, copper, and zinc in anaerobic swine lagoon columns receiving pretreated influent
ABSTRACT Land application of both anaerobic lagoon liquid and sludge can increase nutrient accumulation beyond the soil’s assimilative capacity and become a threat to water quality in regions with intensive, confined swine production. In a 15-month meso-scale column study, we evaluated the effect of manure pretreatment on the reduction of total suspended s

11. Relationship between pseudoexfoliation syndrome and erectile dysfunction: a possible cause of endothelial dysfunction for development of erectile dysfunction
ABSTRACT Objectives: Pseudoexfoliation syndrome (PES) is a common age-related fibrillopathy related to accumulation of pseudoexfoliation material (PEM) in certain places in the body, especially blood vessels. Erectile dysfunction (ED) is another condition related to vascular pathology and in this study it is aimed to ident

12. Canthaxanthin biosynthesis by Dietzia natronolimnaea HS-1: effects of inoculation and aeration rate
The interest in production of natural colorants by microbial fermentation has been currently increased. The effects of D-glucose concentration (3.18-36.82 g/L), inoculum size (12.5 x 10(9)-49.5 x 10(9) cfu cells/mL) and air-flow rate (1.95-12.05 L/L min) on the biomass, total carotenoid and canthaxanthin (CTX) accumulation of Dietzia natronolimnaea HS-1 in a
