Co-regulation of temperature and moisture in the irrigated agricultural ecosystem productivity

Agroecosystem photosynthesis is key to coping with global climate change. In farmland where human activities are highly involved, the interaction between environmental factors and their influences on gross primary productivity (GPP) are insufficiently understood. Particularly, the irrigation and mulching in water-saving agriculture can alter the crop responses to environmental change. Based on edd

Water use efficiency control for a maize field under mulched drip irrigation

Agricultural ecosystem water use efficiency (WUE) is an important indicator reflecting carbon-water coupling, but its control mechanisms in managed fields remain unclear. In order to reveal the influencing factors of WUE in the agricultural field under mulched drip irrigation (DM), we carried out the 8-year continuous observations in a maize field from Northwestern China. The structural equation m

Modeling nitrous oxide emissions from agricultural soil incubation experiments using CoupModel

Efforts to develop effective climate mitigation strategies for agriculture require methods to estimate nitrous oxide (N2O) emissions from soil. Process-based biogeochemical models have been often used for field- and large-scale estimates, while the sensitivity and uncertainty of model applications to incubation experiments are less investigated. In this study, a process-oriented model (CoupModel)

A facile process for adipic acid production in high yield by oxidation of 1,6-hexanediol using the resting cells of Gluconobacter oxydans

Background: Adipic acid (AA) is one of the most important industrial chemicals used mainly for the production of Nylon 6,6 but also for making polyurethanes, plasticizers, and unsaturated polyester resins, and more recently as a component in the biodegradable polyester poly(butylene adipate terephthalate) (PBAT). The main route for AA production utilizes benzene as feedstock and generates copious

Estimating the Length of the Preclinical Detectable Phase for Open-Angle Glaucoma

IMPORTANCE: A 50% reduction of glaucoma-related blindness has previously been demonstrated in a population that was screened for open-angle glaucoma. Ongoing screening trials of high-risk populations and forthcoming low-cost screening methods suggest that such screening may become more common in the future. One would then need to estimate a key component of the natural history of chronic disease,

Negotiating organisational and professional feeling rules: : On digital documentation and emotions in child protection social work

This article explores the emotional challenges of digital documentation practices in child protection social work. Drawing on ethnographic fieldwork in Swedish social services, it explores how social workers negotiate organisational and professional feeling rules when performing child protection investigations using a digital documentation-based structure.

Skadeståndsansvar för juridisk rådgivning

Professionell juridisk rådgivning kräver att rådgivaren gör prognoser om vilka beslut som domstolar eller andra myndigheter kommer att fatta, om klienten väljer att agera på olika sätt. Rådgivaren har både ett fackmässig­hetsansvar och ett upplysningsansvar. Artikeln uppmärksammar ett nytt prejudikat ("Skatterådgivarens ansvarsbegränsning") som bl.a. illustrerar att upplysningsansvaret är långt­gå

QM/MM Study of Partial Dissociation of S2B for the E2 Intermediate of Nitrogenase

Nitrogenase is the only enzyme that can cleave the triple bond in N2, making nitrogen available for all lifeforms. Previous computational studies have given widely diverging results regarding the reaction mechanism of the enzyme. For example, some recent studies have suggested that one of the μ2-bridging sulfide ligands (S2B) may dissociate from one of the Fe ions when protonated in the doubly r

Proton Transfer Pathways in Nitrogenase with and without Dissociated S2B

Nitrogenase is the only enzyme that can convert N2 to NH3. Crystallographic structures have indicated that one of the sulfide ligands of the active-site FeMo cluster, S2B, can be replaced by an inhibitor, like CO and OH−, and it has been suggested that it may be displaced also during the normal reaction. We have investigated possible proton transfer pathways within the FeMo cluster during the

Limiting money : Redesigning the artifact that shapes modern people

The transdisciplinary argument in this article is that the social and ecological unsustainability of modern, globalized capitalism ultimately derives from the design of its central artifact: what Polanyi called all- or general-purpose money. The notion of a singular measure of economic value is a peculiar cultural conception that is inherently at odds with physical reality, yet it pervades modern
