Bismuth oxymetallate-modified biochar derived from Euryale ferox husk for efficient removal of Congo red from wastewater : adsorption behavior and mechanisms

Using Euryale ferox husk as raw material, pristine biochar (EBC), Bi2MoO6-modified biochar (BM-EBC), and BiFeO3-modified biochar (BF-EBC) were prepared and employed for decontaminating Congo red (CR) from wastewater. Compared with EBC (217.59 mg/g) and BF-EBC (359.49 mg/g), a superior adsorption capacity of 460.77 mg/g was achieved by BM-EBC. Based on the evaluation results of the Freundlich and p

Polymer gel dosimetry for experimental verification of conformal small animal irradiation at a preclinical research platform

In translational research, there is a need for preclinical studies of high quality that corresponds to the conformal dose distributions conventionally delivered to humans in the modern radiotherapy clinic. To facilitate this need, novel preclinical systems consist of preclinical radiation platforms and small animal treatment planning systems. However, small-field dosimetry is challenging and requi

A bowhead whale vertebra embedded in marine limit beach sediment on Barentsøya, Svalbard

A cross-valley beach terrace in Iladalen in the south-eastern corner of Barentsøya (Svalbard) is interpreted as built by long-shore sediment transport and deposition, with its maximum height at 88 m a.s.l., marking the marine limit (ML) at deglaciation. A whale vertebra (most probably from a bowhead whale, Balaena mysticetus) was found embedded in the upper part of the littoral sediments at a hei

An Organic Chemistry Odyssey : Imaging Mass Spectrometry in Neurotherapeutics, Asymmetric Methodology Development and Natural Product Synthesis

Första delen i denna avhandling fokuserar på 'Imaging Mass Spectrometry' (IMS), en analytisk teknik med kartografiska egenskaper. Denna teknik används dock inte för att kartlägga geografiska terränger, utan för att skapa kartor över det kemiska landskapet i biologiska prover, från vävnadssnitt av organ eller tumörer till enskilda celler. Dessa kartor visar med hög precision var olika molekyler, såThe development of imaging technologies and brain models is crucial for advancements in neurotherapeutic drug discovery and development. They assume a critical role in evaluating essential parameters such as drug blood-brain barrier (BBB) permeation, distribution, and metabolism, all of which are vital for the development of safe and effective medications. In the first part of this thesis, we expl

Understanding N2O emissions in african ecosystems : Assessments from a semi-arid savanna grassland in senegal and sub-tropical agricultural fields in Kenya

This study is based on the analysis of field-measured nitrous oxide (N2 O) emissions from a Sahelian semi-arid grassland site in Senegal (Dahra), tropical humid agricultural plots in Kenya (Mbita region) and simulations using a 1D model designed for semi arid ecosystems in Dahra. This study aims at improving present knowledge and inventories of N2 O emissions from the African continent. N2 O emiss

The GGCMI Phase 2 emulators : Global gridded crop model responses to changes in CO2, temperature, water, and nitrogen (version 1.0)

Statistical emulation allows combining advantageous features of statistical and process-based crop models for understanding the effects of future climate changes on crop yields. We describe here the development of emulators for nine process-based crop models and five crops using output from the Global Gridded Model Intercomparison Project (GGCMI) Phase 2. The GGCMI Phase 2 experiment is designed w

Per oltre quarant’anni, la scrittura della storia nei paesi dell’Europa orientaleè stata fortemente condizionata dagli imperativi ideologici e propagandisticidei regimi comunisti. La storia, più di ogni altra disciplina umanistica, offrivagiustifi cazioni, e quindi legittimità, al potere. Indagare il rapporto tra storia epotere in questo ambito signifi ca tanto addentrarsi nella storia dei sociali

At the end of the Second World War, Stalin forged the communist regimes in Eastern Europe as satellites of Soviet Union. After ten hard years of Soviet Stalinism, with the changings introduced by the 20th Congress of the CPSU, the leaderships of satellites' communist parties risked to be overthrown by their internal rivals. In Romania, in 1956, Party Secretary Gheorghe Gheorghiu-Dej converted Roma

Writing History in a Propaganda Institute : Political Power and Networking in Communist Romania

In 1990, the Institute for Historical and Socio-Political Studies of the Central Committee of the Romanian Communist Party was closed, since the Party was dissolved by the Romanian Revolution. Similar institutions had existed in all countries belonging to the Soviet bloc. This Institute was founded in 1951 under the name of the Party History Institute, and modelled on the Marx-Lenin-Engels Institu

Urholkade sociala relationer i distansarbete under coronapandemin

Denna artikel har som syfte att förstå hur anställda upplever att relationerna till kollegorna förändrades när de blev förhindrade att mötas fysiskt i det påtvingade distansarbetet under coronapandemin. Studien baseras på djupintervjuer med anställda inom kunskapsintensiva yrken. Resultatet visar på (i) färre kontakter, (ii) minskad tillgänglighet och (iii) försvagad dynamik mellan kollegor. Sluts

Simvastatin is a potential candidate drug in ovarian clear cell carcinomas

Ovarian clear cell carcinomas (OCCC) constitute a rare subtype of epithelial ovarian cancer, lacking efficient treatment options. Based on previous studies, we assessed the anti-proliferative effect of simvastatin, a Rho GTPase interfering drug, in three OCCC cell lines: JHOC-5, OVMANA and TOV-21G, and one high-grade serous ovarian cancer (HGSOC) cell line, Caov3. We used the Rho GTPase interferin

DESMEX: A novel system development for semi-airborne electromagnetic exploration

There is a clear demand to increase detection depths in the context of raw material exploration programs. Semi-airborne electromagnetic (semi-AEM) methods can address these demands by combining the advantages of powerful transmitters deployed on the ground with efficient helicopter-borne mapping of the magnetic field response in the air.The penetration depth can exceed those of classical airborne

Historical carbon dioxide emissions caused by land-use changes are possibly larger than assumed

The terrestrial biosphere absorbs about 20% of fossil-fuel CO 2 emissions. The overall magnitude of this sink is constrained by the difference between emissions, the rate of increase in atmospheric CO 2 concentrations, and the ocean sink. However, the land sink is actually composed of two largely counteracting fluxes that are poorly quantified: fluxes from land-use change and CO 2 uptake by terres

Similar estimates of temperature impacts on global wheat yield by three independent methods

The potential impact of global temperature change on global crop yield has recently been assessed with different methods. Here we show that grid-based and point-based simulations and statistical regressions (from historic records), without deliberate adaptation or CO 2 fertilization effects, produce similar estimates of temperature impact on wheat yields at global and national scales. With a 1 °C

Movement of agricultural products in the Scandinavian Iron Age during the first millennium AD : 87Sr/86Sr values of archaeological crops and animals in southern Sweden

In this paper, we examine the exchange of crops and livestock through the application of strontium (87Sr/86Sr) isotope analysis on cereal grains and faunal tooth enamel from the regional center of Uppåkra and three nearby settlements in Scania, southern Sweden, dating to the first millennium AD. Around a third of the fauna have non-local 87Sr/86Sr values, indicating the import of livestock from se

Diel vertical migration of copepods and its environmental drivers in subtropical Bahamian blue holes

Diel vertical migration (DVM) is the most common behavioral phenomenon in zooplankton, and numerous studies have evaluated DVM under strong seasonality at higher latitudes. Yet, our understanding of the environmental drivers of DVM at low latitudes, where seasonal variation is less pronounced, remains limited. Therefore, we here examined patterns of vertical distribution in copepods in six subtrop
