Passenger and commercial internal combustion engines have relatively large dissipated thermal energy sources that can be used for initiating thermodynamic refrigeration cycles at low temperatures while improving engine efficiency. Researchers have focused on combined power-refrigeration cycles in past studies. This paper presents the operation and performance of a new combined refrigeration system driven by waste heat recovery within the internal combustion engines. For this purpose, the effects of several paramete [...]

The study aims to reveal autism vectors that are inherent in 3-4-year-olds with ASD. Three hundred eighty-three children with ASD took part in the research. An online questionnaire developed earlier by our research group was used. In the first stage, with the repeated use of exploratory factor analysis, the task of identifying the simplest factor structure was solved. As a result, a 7-factor system was obtained, including from 9 to 14 items in each factor (78 items in total): 1) "Persistence on sameness" (Sam); 2) [...]

The Mexican axolotl salamander is an important model species in regenerative medical research and experiments involving this species often require anesthesia which is usually limited to the duration of the surgical procedure or other interventions, usually lasting no more than a few hours. This study aimed to examine the potential for increasing the duration of anesthesia by continued propofol infusion for a week. Neurobehavioral changes in response to prolonged anesthesia were evaluated after two and seven days of [...]

Climate change is one of the main challenges of the current century. Emissions taxes are one of the proposed ways to help in addressing this issue. In this sense, Portugal has introduced an Addition Tax on Carbon Emissions through Law N. 82-D/2014. One of the most notorious impacts of climate change in the country is the wildfires increasing in frequency and intensity. Forests provide various ecosystem services not valued by traditional markets, such as carbon sequestration. Recently, Portugal has created new envir [...]

Various grades of cognitive impairment generally occur in older adults over the age of 55, where cardiovascular risk factors such as diabetes and/or hypertension, coronary artery disease, or cerebrovascular accidents are also common. Cognitive impairment occurs in various forms, from mild or amnesia such as forgetting today's date to more ominous and progressive forms, such as frank dementia. Over 5 million people worldwide suffer from dementia, most of whom live in low- and middle-income countries. It has been env [...]

Traditional approaches to EEG modelling use the methods of classical physics to reconstruct scalp potentials in terms of explicit physical models of cortical neuron ensembles. The principal difficulty with such approaches is that the multiplicity of cellular processes, with an intricate array of deterministic and random influencing factors, prevents the creation of consistent biophysical parameter sets. An original, empirically testable solution has been achieved in our previous studies by a radical departure from [...]

The thermal cracking of methane (TMC) is a significant reaction occurring above 850°C, which proceeds in two stages: non-isothermally and isothermally. However, most existing studies have focused on obtaining reaction rates under isothermal conditions [1], limiting their applicability to practical industrial reactor conditions. This novel research aims to determine the overall thermal decomposition rate of methane to hydrogen and carbon in adiabatic conditions, covering the range of unstable industrial reactor temp [...]

The modern globalized civilization is sustained by interactions, trade, the transportation of goods, and energy. Energy self-sufficiency is crucial in rural and disaster-prone areas like North Euboea because dependence on external energy supplies can leave regions vulnerable to supply chain disruptions, price volatility, and geopolitical risks. In such isolated regions, energy independence ensures resilience in natural disasters and economic instability. The alternative to self-sufficiency often involves reliance o [...]

In the oil distillate fraction alkylation process, a modified Zr zeolite ZSM-5 was obtained and studied. The modification was executed using a method that impregnated ZSM-5 with a 5% solution of ZrOCl2∙6H2O. X-ray diffraction studies were conducted on zeolite ZSM-5, zirconyl chloride modifier ZrOCl2∙6H2O, and modified zeolite ZSM-5-ZrO2, which was calcined at temperatures of 200, 400, and 550°C. The results revealed that the phase composition of modified ZSM-5-ZrO2 zeolite samples varied depending on the calcinatio [...]

Global climate change has necessitated the reduction of GHG emissions. Water distribution system (WDS) pumping adds to these emissions and, therefore, should be reduced. Under electricity hourly cost tariffs, utilities are incentivized to pump during the nighttime hours. This can have a deleterious effect, however, on GHG emissions. To quantify this effect, a modeling study of twelve real WDSs was performed with an electricity tariff. The systems all had the typical tank-level-based pump controls but also time-base [...]

On the natural earth the carbon dioxide count of the atmosphere is a delayed response and an enhancing feedback on the basic cause of the Milankovitch astronomical cycle, the intensity of the June sunshine.
