The calculation of carbon emissions is important to determine the footprint and environmental impact manufacturing processes assess which steps could be further optimized make greener more sustainable. A previously published holistic approach was applied in conventional laser-based material removal most intensive one. were calculated results show that drilling than drilling, while reverse true ...

New rigid polyimides with bulky CF3 groups were synthesized and engineered into high-performance hollow fiber membranes. The enhanced rotational barrier provided by properly positioned CF3 side groups prohibited fiber transition layer collapse during cross-linking, thereby greatly improving CO2 /CH4 separation performance compared to conventional materials for aggressive natural gas feeds.

Background Portugal has a strong tradition of conventional western healthcare. So it provides a natural case study for the relationship between Complementary/Alternative Medicine (CAM) and Western Medicine (WM). This work aims to test the relationship between CAM and WM users in the diagnosis and treatment stages and to estimate the determinants of CAM choice.   Methods The forth Portuguese Nat...

The postweaning IgE and IgG antiovalbumin antibody responses were greater in rat pups which had received a cows' milk-based supplementary feed than in litter mates which had not. This effect was antigen non-specific and might be similar to that of supplementary feeds in the development of atopy in human infants. The total IgE concentration was similar in the two groups. Supplementary feeds did ...

Dear Editor, From energy storage and conversion devices to electroplating corrosion control, electrochemistry is all around us continues evolve, pushing boundaries exploring new frontiers. One such exciting avenue the exploration of in non-conventional electrolytes, which topic this Special Collection containing five excellent contributions from groups Bingwei Mao Jiawei Yang, Björn Braunschwei...

The paper presents a review of results concerning the non-conventional dynamical condensation versus conventional Bose–Einstein condensation, including case generalised van den Berg–Lewis–Pulè condensate. is based on detailed discussion two models: simple toy model and Bogoliubov Weakly Imperfect Bose–Gas model, which was invented for explanation superfluidity liquid $$^{4}{\text{He}}$$ , but a...
