Temperature is a scalar physical quantity, one of the principal parameters determining the state of a thermodynamic system. It corresponds to the average kinetic energy of the motion and vibration of particles in the system. One of the popular methods of temperature recording is the measurement of electromagnetic (infrared, thermal) radiation parameters emitted by a body of a temperature above the absolute zero (0 K or -273.15°C). The measurement is defined as thermography and it is used to produce images of the distribution of temperatures on the surface of an object (objects) with the use of an infrared radiation detector. The main advantage of this type of measurement is its non-invasive nature. Due to the use of a thermographic camera, it is possible to detect most construction defects without interfering in the structure of a building partition. Thermography allows the measurement of temperature in the spaces that are not easily accessible or those where traditional methods are impossible to employ. Thermography is used in a variety of research specialisations. The article presents the results of research relying on the use of thermogram analysis in the estimation of thermal insulation of chosen external building partitions. Much attention was given to façade ...
Municipal Solid Waste (MSW) is the mixture of many waste types, including organic waste (garden and park waste, food and kitchen waste, paper and cardboard etc.). Such waste creates a living environment for various microorganism species, many of which are known as pathogenic. The presence of microorganisms in favorable conditions (pH, organic matter content, carbon content, moisture, appropriate granulation) leads to decomposing of organic matter, which is accompanied by an increase in temperature. Microorganisms in waste pose a serious risk for staff operating at waste treatment plants. Moreover, heat released by their activity may cause a fire in waste storage facilities. Therefore, it is necessary to search for methods of waste stabilization and hygienization. The most commonly applied technology for waste stabilization is its processing in Mechanical Biological Treatment (MBT) plants. Such treatment is capital- and time-consuming, however. Waste liming can become an alternative method for stabilization and hygienization of waste. Lime addition is one of the oldest method known by humans for hygienization of certain waste materials, such as animal waste. Currently, liming is applied in sewage sludge treatment as one of the initial operations and is necessary for further sludge management processes. The aim of the research ...
