Recent advances in thermochemical storage technology have introduced a novel closed-loop thermal energy storage(TES)system,known as the heat battery(HB),which is believed to have great potential for aiding the energy transition in the built environment because of its higher energy density and neglectable storage loss compared to conventional TES *** order to investigate the potential use cases of the HB and provide practical feedback for its further development,this research employs a simulation-based approach to analyze its influence on building performance in various use cases within Dutch residential *** including the homeowner,distribution system operator,and district heating system operator are identified,and a preliminary list of use cases is defined based on relevant literature and input from the HB *** simulation approach is conducted to predict key performance indicators for each *** Kruskal-Wallis test was employed to sort and scrutinize the simulation outcomes and discern the significance of each use case *** findings demonstrated that the HB holds the potential to diminish both the operational energy cost by up to 30%for the homeowners and the peak heating load transmitted from the building to the district heating system.

Background To determine whether the introduction of pasteurized donor human milk and probiotics for infants born<32 weeks gestational age or<1500 g birthweight is associated with a reduction in mortality and the incidence of necrotising enterocolitis (NEC) and sepsis. Methods We performed a retrospective analysis of two cohorts: before and after the introduction of probiotics and pasteurised donor human milk. Univariate analysis of primary and secondary outcomes was performed;variables impacting outcomes were assessed using multivariate logistic regression. Results There were 1791 infants: 1334 in the pre-donor milk/probiotic cohort and 457 in the post-donor milk/probiotic cohort. On univariate analysis, mortality (7.6 vs. 2.4%, P<0.001) and incidence of sepsis (6.2 vs. 3.5%, P=0.028) were statistically significantly lower in the post-donor milk/probiotic group. NEC (2.8 vs. 1.5%, P=0.14) and non-NEC associ-ated gastrointestinal perforation (1.6 vs. 0.4%, P=0.052) were lower in the post-donor milk/probiotics cohort, but these were not statistically significant. The difference in mortality remained statistically significant on multivariate analysis in the post-donor milk/probiotic cohort compared to those in the pre-donor milk/probiotic cohort (odds ratio 0.31, 95% confidence interval 0.16–0.61). The decrease in the incidence of NEC was consistent with previous observational studies but the differ-ence was not statistically significant. Conclusion The availability of probiotics and pasteurised donor human milk is associated with a reduction in mortality in very preterm infants.

The classical dual use problem—the potential for harmful as well as beneficial application of scientific findings—has become more immediate in biotechnology than in most other fields of science. Terrorist misuse of the information on the development of pathogenic organisms can lead to catastrophic outcomes. Therefore, particular in biosciences researchers are faced with the dilemma to find a proper balance between the right to know and the dangers of knowing. In this paper this dilemma is illustrated by the research on the influenza A virus subtype H5N1, commonly known as “bird flu”. The pros and cons of the full publication on the development of a dangerous airborne type are discussed.
