Presently, a variety of methods are employed for the extraction of bioactive compounds from natural sources. These include the use of organic solvents (e.g., methylene chloride), water-based extraction, enzymatic processes, ultrasonic-assisted extraction, microwave-assisted extraction, and extraction utilizing eutectic solvents, such as supercritical carbon dioxide (SC-CO2). Among these, SC-CO2 is recognized for its environmental compatibility and high efficiency........ KEYWORDS:- Caffeine, Extraction, Ultrasonic, Microwave, Tea. @article{key:article,

This paper is a proposed deep learning application to do integrated petrophysical, pore pressure and geomechanics property prediction in unconventional hydrocarbon reservoirs. Simple modeling methodologies in use do not help much in capturing the non-linear multi-attribute interactions that were common in the subsurface conditions (particularly the complex formation in the Permian Basin). To give concurrent estimates of porosity, permeability, pore pressure, Youngs modulus and Poissons ratio, this paper creates a multi-output deep feed forward neural network that is trained on both well logs and seismic-derived properties.......

The high traffic density on Jalan Soekarno Hatta has become a major issue that needs to be addressed immediately. The increase in the number of motor vehicles, both private and public, has created significant pressure on the capacity and functionality of these roads. In addition, the growth of settlements and business sectors around the road creates complexity in land use planning which can have an impact on the feasibility of road functions. Star rating is an evaluative approach used to assess the performance of a road section by considering various aspects, such as physical conditions, safety levels, and user comfort.......

The purpose of this research is to identify the level of reading comprehension of first-semester students at the Pedagogical and Technological University of Colombia, using the illustrative descriptors of the Common European Framework. Secondly, it aims to characterize comprehension levels through six surveys, which will allow for the analysis of reading processes in order to propose strategies for improving reading comprehension. As a basis for the research, a reference framework is created to provide theoretical, contextual, and legal support. Methodologically, this project is based on action research focused on educational practice.......

High-frequency signal reflection characteristics of aqueous NaCl and alcohol solutions were investigated using digital wireless signals of QPSK, 16-QAM, and 64-QAM modulation formats. A vector-signal-generator sent the signals through an SMA probe to aqueous solutions, and a vector-signal-analyzer analyzed the reflected signals through a beam splitter. The concentration of the NaCl solution varied from 0.001 to 3 mol/L, the alcohol concentration ranged from 5 to 99.5%, and the reflected S-parameter (S11) was measured from 1 to 4500 MHz using a vector-network analyzer.........
