Summary
This study models landfill temperature using a linear with sill model, identifying high-temperature zones and establishing average temperature as a key indicator of landfill formation.
Area of Science:
- Geotechnical Engineering
- Environmental Science
Context:
- Semi-aerobic landfilling structures generate internal heat.
- Understanding temperature distribution is crucial for assessing landfill stability and biological activity.
Purpose:
- To model the spatial variability of temperature within a semi-aerobic landfill.
- To interpolate unmeasured temperature values and visualize temperature distribution.
- To identify key temperature indicators for landfill formation.
Summary:
- The semivariogram of temperature in semi-aerobic landfilling structures is effectively modeled by the linear with sill model.
- Spatial temperature analysis revealed high-temperature regions between 3-5.5m vertically in the landfill's middle section.
- The weighted average temperature of 59.80°C serves as a reliable indicator of the landfilling structure's formation and maturity.
Impact:
- Provides a robust geostatistical method for temperature analysis in landfills.
- Enhances understanding of thermal processes within landfill environments.
- Offers a quantifiable metric for assessing landfill operational status and formation.

01:30Diversity of Archaea I
Archaea, a domain of single-celled microorganisms, are classified into five major phyla based on genetic and biochemical characteristics: Euryarchaeota, Crenarchaeota, Thaumarchaeota, Korarchaeota, and Nanoarchaeota. Among these, the phylum Euryarchaeota is notable for its remarkable diversity in morphology, metabolism, and ecological adaptations.Morphological and Metabolic DiversityMembers of Euryarchaeota exhibit a variety of cellular shapes, including rods and cocci. Their metabolic pathways...
01:27Factors Influencing Microbial Growth: Temperature
Microorganisms display remarkable adaptations, enabling them to thrive in diverse ecological niches across a wide range of temperatures. Temperature profoundly influences microbial growth by affecting enzymatic activity, membrane fluidity, and other cellular processes.Each microorganism operates within a specific temperature range defined by three cardinal points: minimum, optimum, and maximum. Below the minimum temperature, membranes lose fluidity, halting transport processes. Above the...
01:22Microenvironments
Microorganisms inhabit highly localized spaces known as microenvironments, which are defined by distinct physical and chemical characteristics. These include oxygen concentration, pH, temperature, light availability, and nutrient levels. The conditions within a microenvironment can differ markedly from those in the surrounding area and significantly influence microbial growth, metabolism, and community structure.Microenvironments often display sharp physicochemical gradients over small spatial...
01:22Mass Concreting
Mass concreting refers to the process of placing large volumes of concrete, such as in gravity dams. The heat generated during the cement hydration process and differential cooling rates within the concrete mass can lead to a temperature gradient, which can result in thermal cracks in the concrete mass.
To reduce the risk of such cracking, the concrete mix may incorporate low-heat cement and pozzolans to reduce the temperature rise. Pre-cooled angular aggregates and water-reducing admixtures...

01:23Physical Methods for Controlling Microbial Growth: Temperature
Heat is a widely used method to control microbial growth by targeting and denaturing cellular proteins, thereby killing or inactivating microbes. This method's effectiveness is quantified using parameters such as the thermal death point (TDP), thermal death time (TDT), and decimal reduction time (D value). TDP represents the lowest temperature at which all microorganisms in a liquid suspension are eliminated within 10 minutes, whereas TDT is the time necessary to achieve sterilization at a...
01:20Hot Weather Concreting
Concreting at elevated temperatures accelerates the hydration process, leading to quicker setting but potentially reducing the long-term strength of the concrete structure. Additionally, low air humidity fosters rapid moisture loss from the concrete, resulting in reduced workability, pronounced plastic shrinkage, and a higher likelihood of crazing.
