All internal combustion engines have a high rate of energy loss while operating; the cooling and exhaust systems of the engine squander the vast majority of the energy generated during combustion. The use of this energy improves engine efficiency. One application of this power is to improve the efficiency of the engine's air pumping, which is done via a turbocharger. Use thermoelectric generators (TEGs) to convert heat energy into electrical energy. A thermoelectric generator type (12715) mounted outside the exhaust terminal was used in this study. A system consisting of four thermoelectric ge

The decline in oil production is currently a big challenge. To overcome this problem, the Enhanced Oil Recovery (EOR) method was used. The EOR method used is surfactants, such as AOS Surfactant (alpha-olefin sulfonate). This laboratory research used five AOS concentrations (0.3; 0.5; 0.75; 0.9; 1%), with a salinity of 7,000 ppm. AOS was chosen because of its ability to reduce interfacial tension. The research carried out was a phase behavior test to assess the stability of the emulsion for 14 days at a temperature of 80C. The process of making a surfactant solution involves mixing AOS powde

This study aims to provide an analysis of a dynamic econometric model and identifies some econometric problems for foreign trade statistics, exports, and imports of Sudan in particular. In addition to identifying some econometric problems using the most frequently used econometric techniques, estimating, and forecasting a dynamic econometric model is also an objective. Box-Jenkins time series models were applied accompanied by results based on different estimation methods such as (OLS) and the Instrumental Variable method to see if valuable findings could be gained. The suggested methodology h

USB drives are widely embraced due to their exceptional portability and convenient size, making them a staple for individuals across various applications. Among their diverse uses, a key function is to serve as a platform for loading operating systems, providing the flexibility to use them anytime, anywhere. While the current methods commonly used for this purpose often necessitate adjusting BIOS settings, creating complexity, and demanding some prior technical knowledge, the suggested solution eliminates this hurdle. It allows users to directly boot from the USB without the necessity of alter

Human health and disease are significantly influenced by the human gut microbiota. Although host gene regulation and the gut microbiota each cause gastrointestinal problems on their own, it is unknown how the two could communicate to affect host pathophysiology. In order to assess matched host transcriptome (n = 50) and gut microbiome (n = 50) profiles from colonic mucosal samples of patients with colorectal cancer, inflammatory bowel disease, and irritable bowel syndrome concurrently, we have created a machine learning-based system. We found correlations between host genes and gut microorgani
