ABSTRACT
Amid a warming planet and a surge in digital activity precipitated by COVID-19 lockdowns, the ecological impacts of cloud infrastructures are of increasing interest to scholars and publics. Deemed "essential workers," data center operators maintain server uptime by keeping equipment cool (via air conditioning). Failure results in overheating and a state of service interruption called downtime. Drawing on ethnographic research in data centers, this article introduces the concept of thermotemporalities to illustrate how time, temperature, and expertise converge in novel formations. By attending to the embodied practices and discursive pronouncements of data center operators, I reveal how uptime (cold) and downtime (hot), a binary opposition, are performative genres rather than discrete referents. Emerging out of this dyadic interplay, I locate a species of aspirational identity I call thermomasculinities.

ABSTRACT
The Bohai Bay as a typical semi-enclosed bay in northern China with poor water exchange capacity and significant coastal urbanization, is greatly influenced by land-based inputs and human activities. As a class of pseudo-persistent organic pollutants, the spatial and temporal distribution of Pharmaceuticals and Personal Care Products (PPCPs) is particularly important to the ecological environment, and it will be imperfect to assess the ecological risk of PPCPs for the lack of systematic investigation of their distribution in different season. 14 typical PPCPs were selected to analyze the spatial and temporal distribution in the Bohai Bay by combining online solid-phase extraction (SPE) and HPLC-MS/MS techniques in this study, and their ecological risks to aquatic organisms were assessed by risk quotients (RQs) and concentration addition (CA) model. It was found that PPCPs widely presented in the Bohai Bay with significant differences of spatial and seasonal distribution. The concentrations of ∑PPCPs were higher in autumn than in summer. The distribution of individual pollutants also showed significant seasonal differences. The high values were mainly distributed in estuaries and near-shore outfalls. Mariculture activities in the northern part of the Bohai Bay made a greater contribution to the input of PPCPs. Caffeine, florfenicol, enrofloxacin and norfloxacin were the main pollutants in the Bohai Bay, with detection frequencies exceeding 80 %. The ecological risk of PPCPs to algae was significantly higher than that to invertebrates and fish. CA model indicated that the potential mixture risk of total PPCPs was not negligible, with 34 % and 88 % of stations having mixture risk in summer and autumn, respectively. The temporary stagnation of productive life caused by Covid-19 weakened the input of PPCPs to the Bohai Bay, reducing the cumulative effects of the pollutants. This study was the first full-coverage investigation of PPCPs in the Bohai Bay for different seasons, providing an important basis for the ecological risk assessment and pollution prevention of PPCPs in the bay. © 2022 Elsevier B.V.
ABSTRACT
After almost three years of an ongoing pandemic, climate change sent its regards this summer to remind humankind of what the future will look like. With political uncertainties arising worldwide, a sustainable oil source becomes increasingly important in both terms: ecological and economical. Yeast oil, triacylglycerides produced by oleaginous yeasts, is a promising alternative or even replacement to plant oils like cocoa butter, palm oil and similar. It has a small ecological footprint, can be produced locally in a reliable manner and has unique characteristics making it functional in multiple applications. The following article aims to give an exciting glimpse into a trending topic and COLIPI, a startup located in Hamburg dedicated to leading the fat revolution. [ FROM AUTHOR]
ABSTRACT
The Outbreak of Covid-19 pandemic has proved to be destructive at economic, social, and ecological ends across the globe. It has disrupted human life in an extremely adverse way. The pandemic aftermath is yet to be completely realised, yet the scale of economic, social, and ecological damage is unfathomable. The situation has elevated the responsibility on entrepreneurial ground to bring in solutions at the affected fronts and work towards sustainability. It is high time to realize the significance of sustainable entrepreneurship at the time when pandemic consequences are severe and still unfolding which will show in the times to come. Though the disruption caused by the pandemic is huge on everyone and everything, the study reveals that sustainable entrepreneurship has comparatively less effect of adversities of COVID-19 than the normal business. This study presents the need and significance of sustainable entrepreneurship to address the damages caused by COVID-19 pandemic. © 2021 IEEE.
ABSTRACT
Compared to the medical, economic and social implications of COVID-19 vaccinations, little attention has been paid to the ecological balance to date. This study is an attempt to estimate the environmental impact of two mRNA vaccines in terms of CO2 equivalents with respect to their different freezing strategies and supply chain organization. Although it is impossible to accurately calculate the actual environmental impact of the new biochemical synthesis technology, it becomes apparent that transport accounts for up to 99% of the total carbon footprint. The emissions for air freight, road transportation and last-mile delivery are nearly as 19 times the emissions generated from ultra-deep freeze technologies, the production of dry ice, glass and medical polymers for packaging. The carbon footprint of a single mRNA vaccine dose injected into a patient is about 0.01 to 0.2 kg CO2 equivalents, depending on the cooling technology and the logistic routes to the vaccination sites in Germany.
