The paper evaluates for the first time the embodied impact in CDW during the buildings life cycle by means of the bill of quantities of construction projects. The main objective is to be able to predict the future CDW to be generated by a project in the design stage, by means of the bill of quantities of the urbanization, construction, renovation, rehabilitation and demolition projects. The tools already in place for cost control can be used as an instrument for the introduction of sustainability considerations in construction projects. The methodology proposes a connection between the different stages of a building's life cycle, more precisely its budget. The latter is linked to other future budgets for building renovations or retrofitting projects. The result shows that urbanization and demolition generate 90% of CDW, the former is caused by earthworks and the latter is due to the elimination of all building materials. The building is removed 1.3 times, in terms of material weight, energy and water. Finally, traditional models for economic control and waste management in construction projects can be the vector which introduce environmental assessment through the building life cycle.

The European catfish (Silurus glanis) is an important species with high economic value, and its growing demand has led to intensive farming practices for it. However, this species is increasingly challenged by parasitic infections, particularly from a specific gill monopisthocotylan parasite called Thaparocleidus vistulensis. To establish effective management strategies, it is crucial to comprehend the fundamental environmental variables that could influence the reproductive and survival behavior of T.

Selective breeding is a potent method for developing strains with enhanced traits. This study compared the growth performance and stress responses of the genetically improved Abbassa Nile tilapia strain (G9; GIANT-G9) with a local commercial strain over 12 weeks, followed by exposure to stressors including high ammonia (10 mg TAN/L), elevated temperature (37 °C), and both for three days. The GIANT-G9 showed superior growth, including greater weight gain, final weight, length gain, specific growth rate, and protein efficiency ratio, as well as a lower feed conversion ratio and condition factor compared to the commercial strain.

Obstructive sleep apnea (OSA), a highly prevalent and serious disorder with significant complications, causes considerable daytime and nighttime symptoms as well as long-term consequences and is yet an underdiagnosed and inadequately treated condition. Patients with OSA undergo frequent awakenings during the sleep cycle and find it impossible to get restorative sleep. Individuals are extremely fatigued, sleepy, and irritable throughout the day.

As the energy density of lithium-ion batteries (LIBs) increases, the shortened cycle life and the increased safety hazards of LIBs are drawing increasing concerns. To address such challenges, a series of localized high-concentration electrolytes (LHCEs) based on a solvating-solvent mixture of tetramethylene sulfone and trimethyl phosphate and a high flash-point diluent 1H,1H,5H-octafluoropentyl 1,1,2,2-tetrafluoroethyl ether were designed. The LHCEs exhibited nonflammability and greatly suppressed heat release at elevated temperatures, which would potentially improve the safety performance of the LIBs.

Fungi play a crucial role in aquatic leaf litter decomposition. Aquatic fungi have long been thought to spend the majority of their lives in the water. Here, we explore the possibility of an amphibious life cycle, where phyllosphere fungi spend part of their life cycle in aquatic systems.
