Effect of Steam Flash Explosion Conditions on Preparation of Reed Pulp
Abstract: The effects of different steam explosion conditions on preparation of reed pulp by steam flash explosion were analyzed. Because the main factors affecting steam explosion are steam pressure, retention time and liquid-to-reed ratio, so that the effects of these conditions on the steam explosion pretreated reed straw, and constituent of reed pulp were analyzed. Reed straw samples, 2~3cm in length, were loaded into a 5L stainless steel reactor and treated …

Managing Pavement Settlement Risk: Impact of Waterlogging and Soil Conditions
Abstract: In the context of road infrastructure, the occurrence of waterlogging due to rainfall can have significant repercussions. Rainwater often infiltrates the road surface and, depending on factors such as the depth of the foundation and the extent of penetration into the ground, can lead to the soil beneath the road becoming either moist or saturated. This, in turn, can result in a reduction of the soil's bearing capacity. When vehicles …

Solubility Enhancement Technique for Verapamil by Solid Dispersion Method
Abstract: By creating a solid dispersion, this study aimed to address the limitations of the traditional solid dosage form of verapamil, including its low bioavailability and restricted clinical efficacy. In order to alter the drug's release and improve its solubility, verapamil solid dispersion was created using the Solvent Evaporation Method and Fusion Method. The physical state of the solid dispersed verapamil was determined using saturation solubility testing and dissolution studies. Verapamil …

The Developed System of Continuous Utilization of Carbon Dioxide, Enrichment of the Atmosphere with Oxygen and Production of Biofuel Using the Resulting Concentrate of Rapidly Multiplying Microalgae
Abstract: It is known that microorganisms, such as microalgae, during photosynthesis utilize carbon dioxide and enrich the atmosphere with oxygen. Microalgae, on the other hand, can be converted into biofuels by extracting fatty acids from macromolecules known as lipids. Recovery of this fatty acid traditionally requires the removal of most of the water from the microalgae resulting in biomass slurry. The method developed earlier permitted to obtain a high-quality concentrate of …

Evaporative Cooling By Using Different Porous Materials
Abstract: The method of evaporative cooling involves raising the air temperature by causing water vapour in an airstream to evaporate. Waterneeds the latent heat of vaporisation to evaporate, and this heat is produced by ambient air and a drop in air temperature. A porousmedium is necessary for both direct and indirect evaporative cooling in order to allow heat and mass transfer between the medium'swater and the air moving through it, or …

Comprehensive Review of EPDM (Ethylene Propylene Diene Monomer) Rubber
Abstract: The terpolymer elastomer known as ethylene propylene diene monomer (EPDM) is made up of ethylene and propylene with trace amounts of a non-conjugated diene as a third monomer. This elastomer was created using the idea of limited olefinic functionality, which is brought about by diene monomer incorporating unsaturation into the polymer backbone. This random elastomeric copolymer, which has a fully saturated polymer backbone, has intriguing qualities such as good heat …

Mechanism of Intensive Gas and Fluid Mixture in the Process of Vibroturbulization and Its Technological Applications
Abstract: Previously conducted experimental studies have established that in a certain narrow frequency range and upon reaching a certain value of the amplitude of water oscillations in a sealed vessel with above-water air shell, subjected to vertical vibration, a resonant phenomenon occurs, called “vibroturbulization”, leading to intensive mixing of media of different density. The studies carried out were purely experimental in nature and could not reveal the physicochemical mechanism of occurrence, …

Synthesis of Biofuel from Castor Oil Using Novel Catalysts
Abstract: An essential step in improving biofuels, especially those made from biomass, is hydrodeoxygenation (HDO). HDO's primary goal is to eliminate oxygen atoms from the biofuel feedstock in the form of water, which enhances the fuel's energy density, stability, and compatibility with current fuel.This study uses a large surface area catalyst to investigate the hydrodeoxygenation (HDOx) activity of non-edible oils. In addition to other supports including H-USY and MCM-41, large surface …
