The exploration of hydrocarbon resources plays a critical role in fulfilling the world’s increasing demand for energy. In this regard, distribution and source rock characteristics coal measure stratum whole basin are important must be studied. However, systematic research has not been conducted yet. study, organic geochemical data, drilling fieldwork were used to examine Upper Paleozoic stratum...

This study focuses on the thermal maturity of Permian deposits from Zagros Basin, Southwest Iran, employing both optical methods (Thermal Alteration Index, Palynomorph Darkness Vitrinite Reflectance, UV Fluorescence) and geochemical analyses organic matter (Rock Eval Pyrolysis MicroRaman spectroscopy) applied to Faraghan Formation along two investigated Darreh Yas Kuh e surface sections. Furthe...

In order to understand the pyrolysis mechanism of β-O-4 type lignin dimers, a pyrolysis model is proposed which considers the effects of functional groups (hydroxyl, hydroxymethyl and methoxyl) on the alkyl side chain and aromatic ring. Furthermore, five specific β-O-4 type lignin dimer model compounds are selected to investigate their integrated pyrolysis mechanism by density functional theory...

Pyrolysis is a promising approach that is being investigated to convert lignin into higher value products including biofuels and phenolic chemicals. In this study, fast pyrolysis of four types of lignin, including milled Amur linden wood lignin (MWL), enzymatic hydrolysis corn stover lignin (EHL), wheat straw alkali lignin (AL) and wheat straw sulfonate lignin (SL), were performed using pyrolys...

In this study, biochar produced by low-temperature pyrolysis from palm leaves was treated with phosphoric acid in order to increase the sorption efficiency of Cr (VI) aqueous solutions. Numerous characterization experiments using BET surface area, FE-SEM and FT-IR showed that acid-treated (TBC-P) covered P particles. comparison biochar, TBC-P also had more oxygenated functional groups, pore siz...

We describe the core of a new strongly-typed functional programming language called LEAP, a \Language with Eval And Polymorphism." Pure LEAP is an extension of the !-order polymorphic -calculus (F ! ) by global de nitions that allows the representation of programs and the de nition of versions of reify, reflect, and eval for all of F ! . Pure LEAP is therefore highly re exive and strongly typed...

Higher-order languages that encourage currying are typically implemented using one of two basic evaluation models: push/enter or eval/apply. Implementors use their intuition and qualitative judgements to choose one model or the other. Our goal in this paper is to provide, for the first time, a more substantial basis for this choice, based on our qualitative and quantitative experience of implem...

background: mucopolysaccharidosis type-vi (mps-vi), which is inherited as an autosomal recessive trait, results from the deficiency of n-acetylgalactosamine 4-sulfatase (arylsulfatase b) activity and the lysosomal accumulation of dermatan sulfate. in this study, arsb mutation analysis was performed on three unrelated patients who were originally from the west azerbaijan province of iran. method...

This paper describes four recent applications of analytical pyrolysis in environmental science and engineering. In all applications, samples were analyzed in order to provide information about the origin of organic matter or changes to an organic matrix. In the first application, pyrolysis-gas chromatography/mass spectrometry (GC/MS) and pyrolysis-GC/flame ionization detection (FID) were used t...

ABSTRACT The II-VI group semiconductors are of great importance due to their applications in various opto electronic devices. Among these semiconductor. Zinc sulphide is the most suitable for its utility in opto electronic devices. Zinc Sulphide has been prepared on glass substrate by using Spray Pyrolysis method. The optical properties of these films have been studied in the wavelength range 3...
