A sulfidic driver for the end-Ordovician mass extinction

The end-Ordovician extinction consisted of two discrete pulses, both linked, in various ways, to glaciation at the South Pole. The first phase, starting just below the Normalograptus extraordinarius Zone, particularly affected nektonic and planktonic species, while the second pulse, associated with the Normalograptus persculptus Zone, was less selective. Glacially induced cooling and oxygenation a

An improved estimation of soil water and salt dynamics by considering soil bulk density changes under freeze/thaw conditions in arid areas with shallow groundwater tables

Soil bulk density (BD) is a parameter dependent on soil texture, compositions of soil minerals and organic matter and the extent of soil compaction. Seasonal freeze/thaw in arid areas with shallow groundwater tables (AASGT) may significantly change BD and hence soil hydrothermal properties and water holding capacity. Therefore, quantifying soil bulk density changes (BDC) under freeze/thaw conditio

Influences of Shifted Vegetation Phenology on Runoff Across a Hydroclimatic Gradient

Climate warming has changed vegetation phenology, and the phenology-associated impacts on terrestrial water fluxes remain largely unquantified. The impacts are linked to plant adjustments and responses to climate change and can be different in different hydroclimatic regions. Based on remote sensing data and observed river runoff of hydrological station from six river basins across a hydroclimatic

Phytolith and simulation evidence for precipitation-modulated vegetation dynamics along the East Asian monsoon margin

An improved understanding of past interactions between terrestrial vegetation and various forcings, such as climate change, human impact, and paleofire, is crucial for assessing impacts of future global change on terrestrial ecosystems. This study seeks to find the key factor or factors that have driven Holocene vegetation change along the East Asian monsoon margin. Several high-resolution pollen

Mycorrhiza-dependent drivers of the positive rhizosphere effects on the temperature sensitivity of soil microbial respiration in subtropical forests

Tree roots and their fungal symbionts mediate the response of rhizosphere soil organic carbon (SOC) decomposition to climate warming, specifically the temperature sensitivity of soil microbial respiration (Q10), which is a critical parameter for projecting the magnitude of terrestrial soil C-climate feedbacks. However, the intensity of the rhizosphere effects (RE; rhizosphere soils vs. bulk soils)

Global parameters sensitivity analysis of modeling water, energy and carbon exchange of an arid agricultural ecosystem

Agricultural ecosystems are important for regulating terrestrial hydrological and carbon cycles. Hydrological and carbon processes in agricultural ecosystem models are complex due to interactions between parameters. It is therefore crucial to identify parameter sensitivity before a process-based model is applied for simulations and predictions of water, energy and carbon fluxes in agricultural ec

Global soil nitrous oxide emissions since the preindustrial era estimated by an ensemble of terrestrial biosphere models : Magnitude, attribution, and uncertainty

Our understanding and quantification of global soil nitrous oxide (N2O) emissions and the underlying processes remain largely uncertain. Here, we assessed the effects of multiple anthropogenic and natural factors, including nitrogen fertilizer (N) application, atmospheric N deposition, manure N application, land cover change, climate change, and rising atmospheric CO2 concentration, on global soil

Cultural Materiality : The correlation between material and cultural capital in the late eighteenth century Stockholm elite burgher home

The eighteenth century saw the slow but steady rise of the middling classes to their nineteenth century social and cultural prominence, reinforced by a changing political landscape and the steadily increasing importance of the market. As the social and cultural power of the city burghers making up the majority of the middling classes grew, so did they start to consume in a manner to reflect to the

Maize residue effects on PM2.5, PM10, and dust emission from agricultural land

Atmospheric particulate matter and dust from agricultural land significantly affect air quality and human health in nearby residential areas. To quantify these air pollutants, it is important to estimate the vertical atmospheric particulate matter PM2.5, PM10, and dust flux using observations and validated models. To the authors´ knowledge, this has previously not been performed for semi-humid agr

De vågade sig ut : en studie av Svenska Mongolmissionens missionärer och verksamhet 1910–1938

The Swedish Mongol Mission (SMM) was an ecumenical union active mostly among Mongols in Outer and Inner Mongolia between 1897 and 1945. SMM were to establish five stations at the borders of the Gobi Desert from 1908 to 1944. The stations were Hallong Osso, Goltjaggan, Dojen, Hatt in Sum, situated in Inner Mongolia and Urga (in present Ulan Bator) situated in Outer Mongolia. In 1950 the activities

Endotoxin, ergosterol, muramic acid and fungal DNA in dust from schools in Johor Bahru, Malaysia - Associations with rhinitis and sick building syndrome (SBS) in junior high school students.

This paper studied associations between ocular symptoms, rhinitis, throat and dermal symptoms, headache and fatigue in students by ethnicity and in relation to exposure to chemical microbial markers and fungal DNA in vacuumed dust in schools in Malaysia. A total of 462 students from 8 randomly selected secondary schools in Johor Bahru, Malaysia, participated (96% response rate). Dust was vacuumed

Low Impact Thinking of the Spongy City Construction in Built-Up Areas from the Perspective of Sustainable Urban Design

Sponge city construction can improve cities’ ability to adapt to the environment change and the ability to cope with floods, and it can also prompt cities’ development to be more healthy and sustainable. However, the process itself of sponge city construction may also has impact on the environment especially in built-up areas, to reduce the impact, the rainwater landscape design needs to integrate

Unveiling stories in Korean smog : a critical discourse analysis of the air pollution policy of Seoul metropolitan government in Korea

Air pollution caused by highly concentrated particulate matter is recognized as the biggest problem in Korean society. Since the problem is directly related to human life and local people's livelihoods, the demand for fundamental policies rather than short-term measures is growing. In this context, the strong policies of Seoul metropolitan government including emergency reduction measures whic

Internet Piracy and Entrepreneurial Growth

Internet Piracy has become a phenomenon as a result of developed Internet technologies and file-sharing applications. With the growth of the Internet and the increased number of Internet users around the globe, the world is becoming ever more digitalized. Users are expecting digital information to be readily available at the touch of a button. This has caused an immense demand for digital goods, w

Towards Circularity in Solar Energy: A Comparative Life Cycle Assessment of Innovative & Conventional PV Modules

Given the increasing share of renewable energy, particularly solar power, there is a growing attention to resource use and disposal challenges associated with Photovoltaic (PV) modules. PV modules consist of multiple layers of materials like silicon, silver, aluminum, glass, and polymers, which makes them difficult to dismantle and recycle. Many recycling methods involve toxic chemicals and create

En litteraturstudie om klorparaffiner i grundvattnet och dess implikationer på hälsa och miljö

Klorparaffiner är ämnen bestående av klorerade kolvätekedjor och kan indelas i tre grupper: korta, mellan och långa ämnesgrupper. Denna rapport syftar till att sammanställa tillgänglig kunskap om klorparaffiner i helhet med inriktning på föroreningens förekomst och dess implikation på grundvatten. Samtliga ämnesgrupper har använts flitigt sedan 1930-talet inom metallbearbetning och plasttillverkniChlorinated paraffins are substances composed of chlorinated hydrocarbon chains and can be categorized into three groups: short, medium, and long chain compounds. This report aims to compile the available knowledge on chlorinated paraffins as a whole, with focus on the occurrence of these pollutants and their implications for groundwater. All groups of chlorinated paraffins have been extensively u
