Summary: The study demonstrates that using a flat tube and dual conic turbulator can enhance the performance of a heat exchanger, resulting in up to 33% higher heat transfers and 30% less exergy loss compared to a plain tube heat exchanger. The heat exchanger with a modified dual turbulator with convergent embellishment was selected as the economic case with the highest thermal performance enhancement factor (TEF) and net profit of unit transferred heat load (eta(p)), showing an increase in eta(p) up to 1.26 times with the application of an enhanced conical turbulator.

Summary: This study experimentally investigated the effects of Al2O3-water nanofluids with different volume concentrations on heat transfer and pressure drop in a mini-channel shell and tube heat exchanger. The results showed that the nanofluids increased the convective heat transfer coefficient in the transition and turbulent regions and extended the transition region. The nanofluids had higher friction factors compared to water. The study also found the optimal volumetric concentration and flow rate for the nanofluids to enhance heat transfer in the heat exchanger.

Summary: The study examines the heat, flow characteristics, and exergy analysis of water passing through a triple ribbed tube heat exchanger using hybrid and single nanoparticles. Computational fluid dynamics modeling was utilized to compare different design and operating parameters, revealing that the hybrid nanofluid of Al2O3+MWCNT/H2O achieved superior heat transfer rates. Further investigation showed that using semi-circular rib shapes in the heat exchanger resulted in increased Nusselt number and effectiveness, but also led to higher exergy loss rates compared to other rib shapes.

Summary: The present study evaluates the thermal performance in a helical double-pipe heat exchanger with an innovative curved turbulator and two types of hybrid nanofluids. Results show that utilizing the innovative turbulator leads to higher heat transfer rate, with Ag-HEG/water hybrid nanofluid performing best at low mass flow rate. The thermal efficiency of the helical heat exchanger is lowest at phi = 0.1%, while the thermal performance is maximum at low mass flow rate for the highest volume concentration (phi = 0.7%).

Summary: This research proposes an unconventional model for thermoelastic dissipation or thermoelastic damping (TED) in circular microplates by incorporating small-scale effect into the structure and heat transfer fields. By utilizing the modified couple stress theory (MCST) and Guyer-Krumhansl (GK) heat conduction model, the coupled thermoelastic equations of motion and heat conduction are derived. The temperature profile in the circular microplate is obtained by solving the equation of heat conduction, and then used in the equation of motion to establish the size-dependent frequency equation influenced by thermoelastic coupling. The precision and accuracy of the proposed model are evaluated by comparing the results with existing literature, and the influence of parameters such as boundary conditions, geometrical features, material and ambient temperature on TED value is emphasized.

Summary: Osteoarthritis (OA) is a common type of arthritis that impacts physical function, particularly in the elderly, and is a leading cause of disability. Joint pain and stiffness are common symptoms of OA, and the main pathological changes involve chondrocyte death and loss of cartilage integrity. Current treatments for OA, such as NSAIDs and glucocorticoids, have limited effectiveness, and there is a need for therapeutic strategies that can halt OA progression.

Summary: Prostate cancer is a highly prevalent malignancy with no cure due to its progressive nature. Genetic and epigenetic alterations play important roles in its development. Apoptosis disruption is a common mechanism in malignancy, and recent evidence suggests that microRNAs have crucial roles in regulating apoptosis in prostate cancer. Understanding the mechanisms by which microRNAs affect apoptosis pathways in prostate cancer can provide new targets for treatment.

Summary: MicroRNA-126 (miR-126) has diverse functions in cancer, affecting tumor angiogenesis, invasion, metastasis, cell proliferation, apoptosis, and treatment resistance. Dysregulation of miR-126 is associated with increased cancer risk and worse prognosis. Targeting miR-126 or its downstream effectors presents a potential therapeutic approach for inhibiting tumor development and combating drug resistance. Further investigation is needed to fully understand the mechanisms behind miR-126 dysregulation and develop efficient therapies.

Summary: Caries is a common chronic oral disease that can lead to secondary caries if traditional filling materials are used. Nanomaterials, such as inorganic nanoparticles, have shown potential in inhibiting biofilm formation, reducing demineralization, and promoting remineralization. Metal and metal oxide nanoparticles, particularly those releasing metal ions, have demonstrated significant antimicrobial activity. Fluoride-functionalized inorganic nanoparticles have also been employed to enhance their effectiveness by promoting remineralization and inhibiting demineralization. This review highlights the recent advances in using inorganic nanoparticles as anti-caries agents and discusses their antimicrobial, remineralizing, and mechanical impacts on dental materials.

Summary: This review discusses the generation of dormant cancer stem cells (CSCs) during tumor development, metastasis, therapy, and immune response. Dormancy determines the time gap between invasive CSCs' organotropism and the occurrence of macrometastasis. Dormancy allows CSCs to evade the immune system and therapeutic agents while supporting their survival and tumor recurrence in specific metastatic sites. The review also presents potential treatments targeting quiescence in CSCs based on their environmental dynamics to enhance cancer therapy outcomes.

Summary: Systems of cogeneration of cooling, heating and electric power with renewable energy sources are an effective solution for reducing dependence on fossil fuels and minimizing environmental pollution. This research utilized an internal combustion engine, a boiler, and a linear parabolic concentrating collector to generate both electrical and thermal energy. The internal combustion engine produced electric power, which was used to generate thermal energy through the concentrated linear collector with the boiler and heat exchanger. A thermal storage tank was employed to store the thermal energy produced by the solar collector and boiler, allowing for supply during required periods. The results demonstrate that the proposed thermal power plant with fossil fuel has lower total costs of final products ($69.3 and $63.5) compared to the fossil system during the hottest month of summer, and also lower total costs ($31.6 and $28.5) during the coldest month of winter.
