Biodiesel was prepared by transesterification process using heterogeneous catalyst has received a lot of interest lately as a sustainable source of biofuel. Hence, there is a need to study a generalized reaction kinetic model that can be used for all the reactions involved in biodiesel production. This study produces biodiesel by transesterifying palm oil using magnetic palm kernel shell-potassium hydroxide. The catalyst recorded a BET surface area of 47.72 m2/g. The maximum biodiesel yield, 95.78%, was obtained when reaction temperature and time were 55°C and 2 hours, respectively.

To increase the filling of the cylinder in the engine, a so-called charge is applied, which consists in increasing the amount of air input under increased pressure and at an unchanged temperature. This increases the density of that air and increases the mass in the engine cylinder. In most cars, the charging is carried out by an exhaust gas turbocharger or a mechanical compressor. This paper presents the issues that concern the failure of turbochargers resulting from their balance by weight reduction method. Selected aspects concerning consequences of incorrect balancing and methods of reducing unbalanced rotor mass. A key part of the work includes a proposal to balance turbochargers of automotive vehicles using the “weight-adjustment” method. In this scope, preliminary studies were presente and conclusions observed during their implementation were described.

Knowledge distillation has gained a lot of interest in recent years because it allows for compressing a large deep neural network (teacher DNN) into a smaller DNN (student DNN), while maintaining its accuracy. Recent improvements have been made to knowledge distillation. One such improvement is the teaching assistant distillation method. This method involves introducing an intermediate "teaching assistant" model between the teacher and student. The teaching assistant is first trained to mimic the teacher, and then the student is trained to mimic the teaching assistant. This multi-step process can improve student performance. Another improvement to knowledge distillation is curriculum distillation. This method involves gradually training the student by exposing it to increasingly difficult concepts over time, similar to curriculum learning in humans. This process can help the student learn in a more stable and consistent manner. Finally, there is the mask distillation method. Here, the student is trained to specifically mimic the attention mechanisms learned by the teacher, not just the overall output of the teacher DNN. These improvements help to enhance the knowledge distillation process and enable the creation of more efficient DNNs.

The monitoring of concrete carbonation takes an important role in the structures maintenance, considering that corrosion induced by this phenomenon is one of the mainly failure causes in the Reinforcement Concrete Structures (RCS) located in industrial zones, roads and cities. Carbonation of concrete is produced by the penetration of the CO2 inside of the porous net, which is mainly combined with the Ca(OH)2 contained in the concrete pore solution producing carbonates with low solubility and eventually causing a pH drop until neutral levels. The pH drop produces the instability and final generalised destruction of the rebars passive layers, which is the step that precedes generalized corrosion. The current existing systems to detect concrete carbonation are based on potentiometric sensors to detect the pH of concrete pore solution. These have some limitations such as the interference of different reactions on the sensor surface. Considering these limitations, in this study a novel system of voltammetric Au sensors embedded in concrete for the detection of concrete carbonation was presented. In the voltammetric sensor, the potential sweep signal applied comprises the potential range where the effect of the pH variations has more influence in the sensor response. Then the response processing by means of the multivariate analysis PCA (principal component analysis) allows to manage a huge quantity of variables and to reduce the effect of the interference with other analytes, increasing the importance of the pH changes effect in the obtained data. Thus, increasing the reliability of the system to detect the concrete carbonation.

The surge of face mask waste in response to the global pandemic has proven to be a liability to the environment. Microfibers from plastic constituents of the face mask would cause microplastic pollution in the water bodies. Fortunately, these waste could be converted into renewable source of energy via thermochemical method, i.e. pyrolysis. However, the studies on the thermal decomposition of face masks and their kinetic mechanisms are not well-established. The aim of this paper focuses on the prospects of pyrolysis at low to high heating rates ranging from 10 °C min-1 to 100 °C min-1, to cater for the slow pyrolysis and fast pyrolysis modes. Following this, the thermal degradation behaviour of the face mask waste was studied via thermogravimetric analysis which determined the single peak temperature degradation range at 218 to 424 °C at 10 °C min-1, and maximum degradation rate was determined at 172.51 wt.% min-1 at 520 °C, with heating rate of 100 °C min-1. Flynn-Wall-Ozawa (FWO) and Starink method was employed to determine the average activation energy and average pre-exponential factor of the pyrolysis process of face mask waste. i.e., 41.31 kJ mol-1 and 0.9965, 10.43 kJ mol-1 and 0.9901 for FWO and Starink method, respectively.

The cracks of the large-area concrete structure in the underground railway section directly affect the structural safety and service life. How to take effective measures to control concrete shrinkage cracks is a difficulty to be solved in the project.In view of the crack control demand of large-area concrete structure cracks in a vehicle section of Wuhan metro, based on the existing engineering cases of large-area concrete structure, shrinkage crack mechanism and control strategies, the corresponding measures are proposed to prevent crack production from two aspects of concrete raw materials and construction technology.The results show that through the regulation of concrete materials,maintenance,casting,post-pouring belt, temperature monitoring and other links, the reduction of shrinkage cracks of large-area concrete structure in the underground railway section is realized.These results can provide references for similar projects to lessen cracks, ensure structural safety and construction quality.

ENERGY!!! In this energy era, when the development of energies and the development of their prices is a daily topic that affects people’s lives, it is necessary to direct our thinking towards the reduction of global energy demands. In my industry, it’s reducing buildings’ energy needs, specifically for heating and cooling. It is known from many researches and studies how it is possible to reduce the energy demand of the building in the area of constructions by insulation, or suitable design of the envelope or in the area of Building services, by using renewable energy sources or by using a suitable source and type of heating and cooling. Therefore, I took a different direction in my research. PASSIVE COOLING. Passive so that we don’t fight against energy with energy, but that we use the amount of it that falls on the object in the largest possible amount and eliminate the rest with suitable design and suitable elements. I focus on VEGETATION and its potential in this direction. My work has several chapters, and in this article I am dealing with one of the first, namely the analysis of the thermal engineering parameters of the constructions in case study A.

The colour of the water can be considered as apparent colour, which is determined by the amount of suspended matter such as clay, phytoplankton and colloidal particles, and true colour, which is the proportion of suspended matter passing through a membrane filter of pore size the 0.45 μm. This study aimed to investigate the apparent and true water colour of pond water and evaluate the impact of filtration on water colour. Using a spectrophotometer, measurements and analyses were conducted on pond water samples. The results of the study showed that filtration can significantly affect the water colour, with a clear difference observed between the apparent and true water colour. The research findings provide a deeper understanding of the factors that influence water colour.

This article shows the different types of biosolar roofs. An important factor that interests me is how a green roof can affect the efficiency of photovoltaics, how it can cool and how much more electricity it can produce than a classic roof. Localized energy generation through rooftop solar is gaining popularity in urban areas, and green roofs are often used for a range of services such as thermal insulation. In recent years, the use of biosolar green roofs to insulate heat and increase solar performance has increased. Two buildings observed by the research team are located in Sydney, Australia, of similar size, location and construction materials. One building has a biosolar roof and the other has a classic solar roof. Each solar array contains a series of environmental sensors including ambient temperature and global horizontal radiation. From the measurement, we can see the results that prove that the biosolar roof had a higher energy output by 4.5%, which proves that it produced 14.26MWh more electricity than the classic solar roof. Compared with previously reported studies and some simulation results, it is clear that the implementation of a bio-solar roof is beneficial for maximizing energy production and reducing greenhouse gas emissions.
