Characteristics of the Ability of Physics Concept in Enrichment Teaching Materials of Natural and Mineral Resources (NMRs) Literacy

This study is aimed at describing the characteristics of basic physics concepts in materials of science literacy enrichment of natural and mineral resources (NMRs) prepared by students of Physics Education Department, Universitas Islam Negeri Sunan Gunung Djati Bandung. The method of data collection for scientific literacy ability of NMRs is obtained from the description of NMRs, results of describing the enrichment materials of NMRs process, the basic concepts of physics, and context as well as attitudes of students towards NMRs through paper enrichment materials. This study was conducted to 15 documents of enrichment materials made by students. The study concluded that: (1) characteristics of students\u27 ability to describe the physics concepts in literacy enrichment materials NMRs show variation; (2) the ability of describing concept of fundamental physics in five NMRs groups being investigated shows a low gains. The study recommends that the application of material needs developing and teaching media literacy enrichment and physical sciences should have more contextual NMRs for secondary, high school and undergraduate students

Building future societies? A brief analysis of Braga’s school bus project

This paper seeks to demonstrate the importance of implementing trans- port policies that meet home to school (and vice versa) mobility needs of children and young people. Over the last few years families’ mobility has been given increasing attention. One of the most investigated aspects is home to work mobil- ity. Nowadays there is an urgent need to study and propose intervention measures regarding children’s mobility to school. In fact, studies show that the car is the preferred mode of transportation in Portugal. This trend has undoubtedly negative social, environmental and health consequences. Based on an evaluation study on the School Bus project in Braga (a research- intervention activity of BUILD-Braga Urban Innovation Laboratory Demonstrator), this paper discusses the difficulties in implementing sustainable mobility initiatives, pointing out anticipatory mea- sures that can be taken in medium-sized cities in order to stop the expansion of children’s transportation by car, and give them back spaces in the cities.UIDB/00736/202

Understanding the complexity of a catalyst synthesis: Co-precipitation of mixed Cu,Zn,Al hydroxycarbonate precursors for Cu/ZnO/Al₂O₃ catalysts investigated by titration experiments

Co-precipitation of Cu,Zn,(Al) precursor materials is the traditional way of synthesizing Cu/ZnO/(Al2O3) catalysts for industrial methanol synthesis. This process has been investigated by titration experiments of nitrate and formate solutions. It was found that the solidification of the single components proceeds sequentially in case of nitrates: Cu2+ is precipitated at pH 3 and Zn2+ (as well as Al3+) near pH 5. This behavior prevents a homogeneous distribution of all metal species in the initial precipitate upon gradual increase of pH and requires application of the constant pH micro-droplet method. This effect is less pronounced if formate instead of nitrate is used as counter ion. This can be explained by the strong modification of the hydrolysis chemistry of the metal ions due to the presence of formate anions, which act as ligands and buffer. A formate-derived Cu/ZnO/Al2O3 catalyst was more active in methanol synthesis compared to a nitrate-derived sample although the same crystallographic phases were present in the precursor after co-precipitation and ageing. The effect of precipitation temperature was studied for the binary CuZn nitrate model system. Increasing the temperature of co-precipitation above 50 °C leads to down-shift of the precipitation pH of Zn2+ by a full unit. Thus, in warm solutions more acidic conditions can be used for complete co-precipitation, while in cold solutions, some Zn2+ may remain dissolved in the mother liquor at the same precipitation pH. The higher limit of temperature is given by the tendency of the initial Cu precipitate towards formation of CuO by oxolation. On the basis of these considerations, the empirically determined optimal pH and temperature conditions of the industrially applied synthesis can be rationalized

A Fiber Bragg Grating—Bimetal Temperature Sensor for Solar Panel Inverters

This paper reports the design, characterization and implementation of a Fiber Bragg Grating (FBG)-based temperature sensor for an Insulted-Gate Bipolar Transistor (IGBT) in a solar panel inverter. The FBG is bonded to the higher Coefficient of Thermal Expansion (CTE) side of a bimetallic strip to increase its sensitivity. Characterization results show a linear relationship between increasing temperature and the wavelength shift. It is found that the sensitivity of the sensor can be categorized into three characterization temperature regions between 26 °C and 90 °C. The region from 41 °C to 90 °C shows the highest sensitivity, with a value of 14 pm/°C. A new empirical model that considers both temperature and strain effects has been developed for the sensor. Finally, the FBG-bimetal temperature sensor is placed in a solar panel inverter and results confirm that it can be used for real-time monitoring of the IGBT temperature

Prevalence, associated factors and outcomes of pressure injuries in adult intensive care unit patients: the DecubICUs study

Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat
