Catalytic fast pyrolysis of sunflower seed shells was performed using a two-stage fixed bed reactor to produce partially deoxygenated bio-oils. Ketonization and aldol condensation reactions were performed in a dual bed r...

An experiment with 630 one-day-old chicks experimentally inoculated with Salmonella Typhimurium was performed to evaluate the effects of an organic acid blend (benzoic, fumaric and 2-hydroxi-4-methylltio-butanoic - HMTBa...

The conversion of greenhouse gas CO2 into novel materials is the most promising approach to solve greenhouse gas issues. Herein, we report for the first time the reaction of potassium with CO2 to synthesize three-dimensi...

ABSTRACT The objective of this study was to estimate the nutritional requirement of digestible methionine + cystine for Japanese quail during the growth phase and its residual effect on the laying phase. One experiment w...

A temporal boundary refers to a specific time at which the properties of an optical medium are abruptly changed. When light interacts with the temporal boundary, its spectral content can be redistributed due to the brea...

O experimento foi conduzido com o objetivo de avaliar os efeitos do nível de substituição da proteína do farelo de soja pela proteína do farelo de coco em rações contendo farelo da castanha de caju sobre o desempe...

The possibility of a type-IIb diamond as the foundation for double-drift region (DDR) impact avalanche transit time (IMPATT) devices that operate at THz frequencies has been investigated. In this study, the large-signal ...

Mualaf are individuals who converted to Islam. The threat of expulsion, termination of financial support, even the threat of termination of kinship is a potential conflict experienced mualaf. This problem has been very h...

In this paper, the catalytic behaviour of two different carbonaceous systems, commercial carbon (Cc) and synthetic carbon (Cs) functionalized with concentrated sulfuric acid (–SO3H) and with reduced aryl diazonium salt...

Dois experimentos foram realizados com o objetivo de determinar as relações adequadas de arginina:lisina, isoleucina:lisina, valina:lisina e triptofano:lisina digestíveis para frangos machos nas fases inicial (7 a 21 ...

Abstract Biological production of adipic acid, a crucial building block in nylon and polymer manufacturing, from renewable feedstocks has attracted attention as a sustainable alternative to the traditional petrochemical ...

The scientific literature on the electrochemical conversion of CO2 on silver and silver-based cathodes in aqueous solutions and nonaqueous media has been analyzed. It has been shown that the most problematic issues regar...

Different basic materials, such as K-L zeolite, K-Al2O3, K-Mg/Al mixed oxide and MgO, were used as supports of Pt-catalysts for the dry reforming of methane (DR) reaction. The effects of the distribution of basic strengt...

The objective of this study was to compare fattening performance, carcass traits, and egg quality of Japanese quails with different feather colors (white, dark brown, golden, and wild-type). In the study, 360 one-day-old...

Solar iron production from H2-based direct reduction of iron ore was investigated in a continuously particle-fed reactor for performance analysis. Concentrated solar energy was used as the external source of high-tempera...

Chirality prevails in nature and is of great value for molecular biology, medicine, and bioscience. Due to the enhancement of chiroptical responses, chiral metasurfaces has attracted enormous attentions. In this paper, s...

Avaliaram-se os efeitos de níveis de cálcio e da suplementação de dietas com mananoligossacarídeos sobre desempenho e a viabilidade econômica de codornas em postura. Foram utilizadas 200 codornas em delineamento in...

This study evaluated the relationship between digestible lysine and metabolizable energy for barrow and gilts from 24 to 50 kg. Performance, digestibility and blood profile were studied. The experimental design was of ra...

Um experimento foi conduzido com o objetivo de avaliar a utilização de farelo do resíduo de manga (FRM) (Mangifera indica L., var. Ubá) em rações para frangos de corte de 1 a 42 dias de idade. Utilizaram-se 600 pin...

The effects of different concentrations of biological nitrification inhibitors(methyl p-hydroxyphenylpropionate(MHPP), syringic acid(SA)) and chemical nitrification inhibitors(dicyanediamine(DCD), 3, 4- dimethyl-1H-pyraz...
