Purpose: Climate modification and population increase are threatening water supplies. The world's population have tripled ever since the turn of the century, nonrenewable energy demand has climbed by a ratio of 30, while occupational production had also risen by a ratio of 50. Theoretical Framework: Problem sizing and structure, model conceptualization, model implementation and testing, and scenarios analysis are the four phases of a conventional SD modeling framework. Methods: This indicates that as a result of occupational, agricultural, and urban usage, there is a rising demand for water and a diminishing supply of resources of sufficient quality. Due to the effects of climate change, unkind ocean smooth rose by 0.19 m among 1901 and 2010. Anthropogenic climate change is known to have impacted the incidence and magnitude of flooding. Globally, the recent identification of growing vogues in precipitation and large flows in specific basins suggests a larger impact. Results: This research article takes stock of the evaluation of the influences of climate change on water transport capacity, in particular using the Vensim model. In this research review, for the analysis or estimate of the impacts of climate change on the water transport capacity, Vensim was investigated using a system dynamics technique to simulate the basin slopes of the supply systems to study climatic effects. Conclusions: It was concluded that the combination of different adaptation strategies, such as desalination, the construction of dams and the promotion of water conservation, has the greatest effects in reducing the impacts of climate change.

High sugar intake from commercial beverages is a public health concern, motivating rapid, user-friendly tools for sugar quantification. We present a compact planar microwave metamaterial sensor that estimates sugar concentration by monitoring resonant frequency shifts induced by dielectric loading. Tests with aqueous glucose solutions demonstrated a wide dynamic range (0 to 12,000 mg/dL), perfect linearity (R² = 1), and high repeatability. Validation on two commercial beverages showed sensor-predicted sugar contents consistent with their nutrition labels. The method is reagent-free, tolerates opaque samples, and operates under ambient conditions, making it suitable for on-site consumer use as well as regulatory inspection and quality-control applications.

C-wing design is one of many non-planar wings that can improve aerodynamic performance without compromising the aspect ratio of a typical aircraft. This paper presents and compares the aerodynamic characteristics of planar wings and C-wings with backward and forward swept configurations at transonic speed in terms of lift coefficient (C_L), drag coefficient (C_D), drag polar, and lift-to-drag ratio (C_L/C_D). The ONERA M6 wing was used as a benchmark in this study. The numerical analysis was conducted at a constant Mach number of 0.8395 with α ranging from 0° to 10° using the Spalart-Allmaras turbulence model. The results show that the Backward Swept C-wing (BSCW) delays the stall angle compared to the Backward Swept Wing (BSW). The Forward Swept Wing (FSW) and Forward Swept C-wing (FSCW) can operate at high α without showing signs of stalling. Furthermore, operating above the intersecting point, the C-wing configurations exhibit better drag reduction for a specific C_L value compared to their respective planar counterparts. The C_L/C_D curves provide insight into the aerodynamic efficiency of the four wing configurations. The preliminary results indicate that both the BSCW and FSCW of this study can produce more lift and delay stalling α compared to their respective BSW and FSW counterparts. However, the C_L/C_D performance of both the BSCW and FSCW is comparatively lower than BSW and FSW, respectively, due to the interference of shock waves between the wing and C-winglet. This paper provides insight into the potential advantages and disadvantages of using C-wings in aircraft design. The findings of this study can inform future efforts to optimize aircraft performance by improving aerodynamic efficiency while maintaining similar levels of lift.
