Illuminating practitioner challenges in energy transitions.

Sustainable development (SD) is a concept that can be used to address complex challenges, including energy transitions. SD offers diverse strategies that provide useful direction in navigating tensions, trade-offs and synergies in energy transitions. The purpose of this research was to identify the challenges that energy practitioners are faced with in energy transitions and explore potential solutions.

Energy poverty: an overlooked determinant of health and climate resilience in Canada.

Objective: Despite Canada being an important energy producer, not all Canadians can access or afford adequate levels of energy services at home to meet their needs, maintain healthy indoor temperatures, and live a decent life-a situation known as energy poverty. Depending on the measure, 6-19% of Canadian households face energy poverty. Health risks associated with energy poverty are documented in countries with milder climates.

Methodology to identify demand-side low-carbon innovations and their potential impact on socio-technical energy systems.

The rapid diffusion of demand-side low-carbon innovations has been identified as a key strategy for maintaining average global temperature rise at or below 1.5 °C. Diffusion research tends to focus on a single sector, or single technology case study, and on a small scope of factors that influence innovation diffusion.

Molar incisor malformation in six cases: description and diagnostic protocol.

Objective: The term molar-incisor malformation (MIM) has recently been presented in the scientific literature, where it is described as a condition with localized impaired root development. Here we present 6 recently discovered cases referred to our departments.

Study Design: The patients were enrolled in the study after referral and were examined clinically and radiologically.

Occurrence of Anxiety and Depression among Stable COPD Patients and its Impact on Functional Capability.

Introduction: Anxiety and depression are important but often under-diagnosed co-morbid conditions in patients with Chronic Obstructive Pulmonary Disease (COPD) which may affect the functional capacity of the patients.

Aim: To find out the proportion of depression and anxiety among stable COPD patients using a validated questionnaire suitable for use in clinic and the factors affecting their reduced functional capability as assessed by six-minute walk test.

Materials And Methods: This was a descriptive cross-sectional study.

Negative numbers in simple arithmetic.

Are negative numbers processed differently from positive numbers in arithmetic problems? In two experiments, adults (N = 66) solved standard addition and subtraction problems such as 3 + 4 and 7 - 4 and recasted versions that included explicit negative signs-that is, 3 - (-4), 7 + (-4), and (-4) + 7. Solution times on the recasted problems were slower than those on standard problems, but the effect was much larger for addition than subtraction. The negative sign may prime subtraction in both kinds of recasted problem.
