Towards sustainable energy culture in the industrial sector:introducing an interdisciplinary method for understanding energy culture in business industries

Abstract Background There have been numerous research papers focusing on improving energy consumption and energy behaviour in domestic and residential contexts. However, workplaces and especially industry settings have gained less attention in scientific literature, even though the industry sector is one of the largest energy consumers in the world. This article introduces a methodological framework that utilizes the energy culture concept, to support understanding the factors that influence energy culture at business industry companies. Methods Building on the concept of energy culture, we introduce an interdisciplinary method, which assesses organizations’ energy culture from different perspectives and recognizes the possibilities for sustainability transitions. To validate this method, the developed energy culture survey has been verified by 27 expert participants from different industry-related companies located in Finland, Italy, Switzerland, Germany France, and Austria. Results Our analysis highlights the need to consider diverse, interdisciplinary aspects to create a successful method for enhancing energy culture in the industrial sector. This will take into consideration human aspects, related to cognitive norms, beliefs, and aspirations, as well as to human interaction with the material world. Conclusions Industrial energy cultures context differs from domestic and residential contexts, and the knowledge from one context cannot be transferred to another context as such. Based on investigated studies undertaken for residential, office, and other sectors and the lessons learned, we developed a systematic method for energy culture understanding in industries. Energy managers may use it, as well as other individuals involved in energy culture issues in the industrial business sector, to evaluate the state of energy culture and engage employees towards new energy-related practices

Citizens and positive energy districts:Are espoo and leipzig ready for PEDs?

In urban transformation, no solution works without citizen support. With increasing numbers of building technologies and large-scale urban development on its way across cities, it has become vital to keep citizens informed, engaged, and content with the new changes. This paper looks at citizen engagement in Espoo (Finland) and Leipzig (Germany), and it determines whether the cities are ready for developing and implementing positive energy districts (PEDs). The authors studied the cities’ operations and current citizen engagement methods to understand how the efforts could be combined and improved. The analysis indicated that the city of Espoo already has a well-established system that continuously promotes citizen engagement at various levels, and combining the available infrastructure with company experts on citizen participation will allow Espoo to seamlessly transition towards PEDs in the near future. The city of Leipzig has a rich experience due to several national projects and participation in an earlier European project, which enabled the city to set clearer goals for the future and modify existing citizen methods. As lighthouse cities, findings from Espoo and Leipzig are also aimed at cities across Europe and beyond to boost development of PEDs together with citizens

RESPONSE OF SUNFLOWER TO VARIOUS PRE-GERMINATION TECHNIQUES FOR BREAKING SEED DORMANCY

Abstract Seed dormancy is considered to be a serious constraint in sunflower seed production. Viable seeds sometimes do not germinate even in the presence of favorable environmental conditions. Such seeds are suspected to be dormant. The study was conducted under controlled/laboratory conditions during spring 2010 at National Agricultural Research Centre, Islamabad. The objective of the study was to evaluate some techniques to convert a seed from dormant to non-dormant germinable state. Dormant seeds of 21 sunflower hybrids were treated with three hot water treatments (100°/80°C) and four chemicals potassium nitrate, 0.2%, thiourea, 0.5%, ethanol, 25%, acetone, 25% for breaking seed dormancy .The untreated seed was taken as control. Soaking seeds in hot water (80°C) for 15 minutes followed by one day dry and seed treatment with acetone were found to be the most effective and successful techniques in converting the seed from dormant to nondormant state

Global burden of 288 causes of death and life expectancy decomposition in 204 countries and territories and 811 subnational locations, 1990–2021: a systematic analysis for the Global Burden of Disease Study 2021

BACKGROUND Regular, detailed reporting on population health by underlying cause of death is fundamental for public health decision making. Cause-specific estimates of mortality and the subsequent effects on life expectancy worldwide are valuable metrics to gauge progress in reducing mortality rates. These estimates are particularly important following large-scale mortality spikes, such as the COVID-19 pandemic. When systematically analysed, mortality rates and life expectancy allow comparisons of the consequences of causes of death globally and over time, providing a nuanced understanding of the effect of these causes on global populations. METHODS The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2021 cause-of-death analysis estimated mortality and years of life lost (YLLs) from 288 causes of death by age-sex-location-year in 204 countries and territories and 811 subnational locations for each year from 1990 until 2021. The analysis used 56 604 data sources, including data from vital registration and verbal autopsy as well as surveys, censuses, surveillance systems, and cancer registries, among others. As with previous GBD rounds, cause-specific death rates for most causes were estimated using the Cause of Death Ensemble model-a modelling tool developed for GBD to assess the out-of-sample predictive validity of different statistical models and covariate permutations and combine those results to produce cause-specific mortality estimates-with alternative strategies adapted to model causes with insufficient data, substantial changes in reporting over the study period, or unusual epidemiology. YLLs were computed as the product of the number of deaths for each cause-age-sex-location-year and the standard life expectancy at each age. As part of the modelling process, uncertainty intervals (UIs) were generated using the 2·5th and 97·5th percentiles from a 1000-draw distribution for each metric. We decomposed life expectancy by cause of death, location, and year to show cause-specific effects on life expectancy from 1990 to 2021. We also used the coefficient of variation and the fraction of population affected by 90% of deaths to highlight concentrations of mortality. Findings are reported in counts and age-standardised rates. Methodological improvements for cause-of-death estimates in GBD 2021 include the expansion of under-5-years age group to include four new age groups, enhanced methods to account for stochastic variation of sparse data, and the inclusion of COVID-19 and other pandemic-related mortality-which includes excess mortality associated with the pandemic, excluding COVID-19, lower respiratory infections, measles, malaria, and pertussis. For this analysis, 199 new country-years of vital registration cause-of-death data, 5 country-years of surveillance data, 21 country-years of verbal autopsy data, and 94 country-years of other data types were added to those used in previous GBD rounds. FINDINGS The leading causes of age-standardised deaths globally were the same in 2019 as they were in 1990; in descending order, these were, ischaemic heart disease, stroke, chronic obstructive pulmonary disease, and lower respiratory infections. In 2021, however, COVID-19 replaced stroke as the second-leading age-standardised cause of death, with 94·0 deaths (95% UI 89·2-100·0) per 100 000 population. The COVID-19 pandemic shifted the rankings of the leading five causes, lowering stroke to the third-leading and chronic obstructive pulmonary disease to the fourth-leading position. In 2021, the highest age-standardised death rates from COVID-19 occurred in sub-Saharan Africa (271·0 deaths [250·1-290·7] per 100 000 population) and Latin America and the Caribbean (195·4 deaths [182·1-211·4] per 100 000 population). The lowest age-standardised death rates from COVID-19 were in the high-income super-region (48·1 deaths [47·4-48·8] per 100 000 population) and southeast Asia, east Asia, and Oceania (23·2 deaths [16·3-37·2] per 100 000 population). Globally, life expectancy steadily improved between 1990 and 2019 for 18 of the 22 investigated causes. Decomposition of global and regional life expectancy showed the positive effect that reductions in deaths from enteric infections, lower respiratory infections, stroke, and neonatal deaths, among others have contributed to improved survival over the study period. However, a net reduction of 1·6 years occurred in global life expectancy between 2019 and 2021, primarily due to increased death rates from COVID-19 and other pandemic-related mortality. Life expectancy was highly variable between super-regions over the study period, with southeast Asia, east Asia, and Oceania gaining 8·3 years (6·7-9·9) overall, while having the smallest reduction in life expectancy due to COVID-19 (0·4 years). The largest reduction in life expectancy due to COVID-19 occurred in Latin America and the Caribbean (3·6 years). Additionally, 53 of the 288 causes of death were highly concentrated in locations with less than 50% of the global population as of 2021, and these causes of death became progressively more concentrated since 1990, when only 44 causes showed this pattern. The concentration phenomenon is discussed heuristically with respect to enteric and lower respiratory infections, malaria, HIV/AIDS, neonatal disorders, tuberculosis, and measles. INTERPRETATION Long-standing gains in life expectancy and reductions in many of the leading causes of death have been disrupted by the COVID-19 pandemic, the adverse effects of which were spread unevenly among populations. Despite the pandemic, there has been continued progress in combatting several notable causes of death, leading to improved global life expectancy over the study period. Each of the seven GBD super-regions showed an overall improvement from 1990 and 2021, obscuring the negative effect in the years of the pandemic. Additionally, our findings regarding regional variation in causes of death driving increases in life expectancy hold clear policy utility. Analyses of shifting mortality trends reveal that several causes, once widespread globally, are now increasingly concentrated geographically. These changes in mortality concentration, alongside further investigation of changing risks, interventions, and relevant policy, present an important opportunity to deepen our understanding of mortality-reduction strategies. Examining patterns in mortality concentration might reveal areas where successful public health interventions have been implemented. Translating these successes to locations where certain causes of death remain entrenched can inform policies that work to improve life expectancy for people everywhere.

Freshwater Algae: Essential Nutrients and Factors

Algal growth in an acidic environment was analyzed using Algae Turf Scrubbers (ATS). The main objective was to assess and understand the role of nutrients and other environmental factors including temperature, pH and turbidity necessary for algal growth. The acidic environment was achieved by the addition of heavy metal contaminated processed wastewater to the ATS and monitoring the growth pattern over a course of 6 weeks. A total of 10 freshwater species were first cultivated separately and later on added to the ATS systems. The results demonstrated that only a few freshwater species survived namely Anabaena, Synechococcus, Fragalaria and Scenesdesmus. It was observed that a low Redfield Ratio, suitable temperature and low turbidity played a crucial role in the significant increase in cyanobacteria population. The ATS simulated the natural freshwater environment and helped get valuable insight regarding algae and heavy metals

The roadmap to an Ecocampus: Understanding the interplay between learning space and energy efficiency

The thesis demonstrated that space management must be part of the real estate strategy and that spaces must be constructed on the basis of common known (e.g required equipment) and unknown factors (e.g. increase in student numbers). The questionnaire showed that lack of versatility, services and indoor comfort contribute to making a space inefficient. Consequently, they affect the user’s choice of space as many do not wish to spend time at the studied building unless they have study tasks, which is why low occupancy levels were observed during the study. Measurements such as specific energy consumption adjusted for occupancy (SECo) & Specific energy for usage and space efficiency (SECus) are good indicators since they take into account occupancy rates, daily hours and space per person (m2/person). In this particular studied building, the equipment and users cause merely one-fifth of the consumption and the remaining consumption is attributed to the fact that the building has a high base consumption. In conclusion, this thesis urges the campus management to provide inspiring and versatile spaces to the community since this will not only lead to enhanced space utilization, but also decrease the amount of wasted energy in the form of unused spaces. Such efforts will also encourage efficiency of older buildings, since new buildings are more energy efficient, thus leading the university campus to achieve a balance in space and energy efficiency
