Summary
Urbanization in India significantly increases land surface temperature (LST) and heat islands. This study links land use changes to LST variations, highlighting risks and recommending sustainable urban planning.
Area of Science:
- Environmental Science
- Urban Planning
- Remote Sensing
Background:
- Rapid, unplanned urbanization and decreased forest cover are critical issues in India.
- These changes lead to increased land surface temperature (LST), urban heat islands, and health risks.
Purpose of the Study:
- To assess the interrelationship between LST and land use/land cover (LULC) dynamics.
- To analyze seasonal LST variations and their connection to land indices and LULC changes in West Bengal, India.
Main Methods:
- Extraction of LST using satellite imagery.
- Analysis of seasonal LST variations and relationships with NDVI, NDBI, NDMI, and NDWI.
- Hotspot analysis of LULC dynamics from 1988 to 2023.
Main Results:
- Built-up areas increased by 51%, while fallow land decreased by 73%.
- Higher LST changes (3.41°C) observed in high-density built-up areas.
- A positive correlation between Normalized Difference Built-up Index (NDBI) and LST (r²=0.59) was found.
Conclusions:
- Findings reveal significant LST fluctuations influenced by LULC dynamics, posing climatic and health hazards.
- Planned urban expansion, efficient LULC management, and green space promotion are recommended for sustainable development.

01:18Boundary Layer Characteristics
57
When a fluid encounters a solid surface, a boundary layer forms due to the interaction between the fluid's motion and the stationary surface. This phenomenon is characterized by a thin region adjacent to the surface where viscous forces dominate, influencing the fluid's velocity profile. The development of the boundary layer begins at the leading edge of the surface and evolves as the fluid moves downstream.As the fluid flows over the surface, friction between the fluid and the wall slows down...

01:12Precipitation Processes
430
The experimental conditions in a gravimetric analysis should be optimized to maximize the particle size and purity of the obtained precipitate. Ideally, the concentration of the precipitating reagent should be low with effective stirring to maintain low relative supersaturation for the growth of large crystals. In homogeneous precipitation, the precipitant is slowly generated by a chemical reaction in the solution to avoid local reagent excesses. For example, urea decomposes gradually to...

Fluid dynamics is the study of fluids in motion. Velocity vectors are often used to illustrate fluid motion in applications like meteorology. For example, wind—the fluid motion of air in the atmosphere—can be represented by vectors indicating the speed and direction of the wind at any given point on a map. Another method for representing fluid motion is a streamline. A streamline represents the path of a small volume of fluid as it flows. When the flow pattern changes with time, the...

Precipitation gravimetry is based on converting an analyte into a sparingly soluble precipitate, which is separated by filtration and weighed. An ideal precipitate should be pure, insoluble, of known composition, and easily filtered from the reaction mixture.

3.4K
A thermodynamic process that occurs at constant volume is called an isochoric process. According to the first law of thermodynamics, heat supplied or removed from the system is partially utilized to perform work and change the internal energy of the system. However, in an isochoric process, the volume remains constant. Hence, the work done by the system is zero. Therefore, the exchange of heat changes the internal energy of the system only.

The Region of Convergence (ROC) is a fundamental concept in signal processing and system analysis, particularly associated with the Laplace transform. The ROC represents an area in the complex plane where the Laplace transform of a given signal converges, determining the transform's applicability and utility.
