This dataset contains 300 seismic models of Mars compatible with seismic travel times of marsquakes observed until January 2021. The inversion is described in detail in Stähler et al. (2021): Seismic detection of the Martian Core, Science. See the description therein. The provided zip file contains 100 models each of the "geophysical", "geodynamical" and "seismic" inversion. All model files are provided in the nd format of TauP. For compatibility reasons, each model has a small inner core. This is not a feature resolved by the inversion.

Abstract Heavy mineral component of 13 samples from the Lokoja and Patti Formations, Bida Basin have been studied for their textural characteristics, compositional abundance, maturity and provenance determinations. The suite of heavy minerals encountered is classified as opaque and non-opaque constituents. The non-opaque components include zircon, tourmaline, rutile, garnet, staurolite, epidote, kyanite, titanite, lawsonite, cassiterite, sillimanite, hornblende, hypersthene and andalusite. The assemblage is generally dominated by zircon and tourmaline in the two formations. The constituent heavy minerals identified are dominated by ultra-stable and stable classes, whereas the ZTR indices indicate mineralogical immaturity coupled with textural immaturity of the constituent grains. This suggests the possible dominance of chemical weathering of the source rock. The suites of minerals recovered have been linked to both metamorphic and non-metamorphic crystalline rock origins.

Os Vales da Uva Goethe são uma região produtora de Uva e Vinho localizada no Sul de Santa Catarina, compreendendo oito municípios. Em 2012, essa produção conquistou o registro de Indicação de Procedência Vales da Uva Goethe. Diante do exposto, o presente estudo objetivou identificar a visão do setor supermercadista em relação aos vinhos produzidos com o registro de Indicação de Procedência dos Vales da Uva Goethe na cidade de Criciúma – SC. Metodologicamente, esta pesquisa caracterizou-se como descritiva quanto aos fins e de campo quanto aos meios de investigação. A população-alvo foi delimitada pelos supermercados da cidade de Criciúma – SC, caracterizadas pelos sommeliers ou responsáveis pela compra de vinhos do estabelecimento. Verificou-se que os sommeliers sabem o que é Indicação Geográfica, ao contrário dos consumidores. Os vinhos e espumantes dos Vales da Uva Goethe são comercializados em 50% dos supermercados. Apesar de o consumo de vinhos nacionais crescer, o consumidor tem preferência pelos importados, principalmente os chilenos.

Abstract Bacteria are considered as foremost bioremediating agents among microorganisms, encompassing simple biological mechanism to tolerate higher concentration of heavy metal and favoring conservative strategies to substitute the usage of chemicals. Relating this implication, the present study is designed to identify, screen and characterize bacteria from industrial site soil to tolerate multimetals. Almost 108 colonies were obtained at various concentrations (0.5–2.0 mM) of heavy metals (cadmium, nickel and lead) and were thrived in the reformed minimal media. Bacterial isolates that grown in the higher concentration of heavy metals (2.0 mM) were taken for further studies. Among ten bacterial colonies, one isolate was selected for each heavy metal and further screened for their multi metal tolerance. Isolate, C20 alone survived in heavy metal mixture fortified medium with high recovery rate and increased colony forming units. Molecular level characterization and phylogenetic tree analysis revealed that the isolate is identical to Bacillus thuringiensis. The study highlights that the multi metal tolerant B. thuringiensis could be used as an effective bioremediating agent to manage heavy metals particularly cadmium, nickel and lead in industrial area. Further, attributed to be a plant growth promoting rhizobacteria, this organism can promote dual stratagems as a bio remediating agent and fertility enhancer in agricultural field due to its dual functions.

Breast milk might be a source of potentially toxic metals such as cadmium (Cd). The purpose of the present study is to provide data pertaining to the influence of maternal lifestyles on Cd concentrations in breast milk in the Austrian setting. Breast milk was obtained from 124 Austrian women. Each participant provided 10 ml of milk. A second group of eight mothers were recruited to investigate changes in their milk cadmium levels at 1, 3, 5, 7 and 9 weeks post partum. The study participants filled a questionnaire concerning nutrition, supplementation, and smoking habits. The samples were analyzed using GF-Atomic Absorption Spectrophotometer (AAS). The mean Cd content in breast milk was among the lowest in Europe (0.086 +/- 0.085 microg/l, 95% CI: 0.07-0.10; n = 124). Increased Cd levels in breast milk were found to be significantly associated with frequent cereal consumption and smoking. Smokers had a two-fold higher concentration than did non-smokers (0.15 versus 0.07 microg/l; P = 0.000). In contrast, low Cd levels in breast milk were associated with the intake of supplements containing trace elements or vitamins and trace elements (P0.05). This protective effect of supplements on Cd levels was only observed in non-smokers. The Cd levels registered in the present investigation were far below critical levels. We conclude that the current maternal Cd levels in Austria signify no risk for the breastfed infant of a healthy mother. Further research will have to focus on the specific effects of supplementation and smoking on Cd concentrations.

Abstract Although the adverse impacts of emerging nanoparticles (NPs) on the biological nitrogen removal (BNR) process have been broadly reported, the adaptive responses of NP-impaired nitrifiers and the related mechanisms have seldom been addressed to date. Here, we systematically explored the adaption and recovery capacities of the ammonia oxidizer Nitrosomonas europaea under chronic TiO2 NP exposure and different dissolved oxygen (DO) conditions at the physiological and transcriptional levels in a chemostat reactor. N. europaea cells adapted to 50 mg/L TiO2 NP exposure after 40-d incubation and the inhibited cell growth, membrane integrity, nitritation rate, and ammonia monooxygenase activity all recovered regardless of the DO concentrations. Transmission electron microscope imaging indicated the remission of the membrane distortion after the cells' 40-d adaption to the NP exposure. The microarray results further suggested that the metabolic processes associated with the membrane repair were pivotal for cellular adaption/recovery, such as the membrane efflux for toxicant exclusion, the structural preservation or stabilization, and the osmotic equilibrium adjustment. In addition, diverse metabolic and stress-defense pathways, including aminoacyl-tRNA biosynthesis, respiratory chain, ATP production, toxin-antitoxin ‘stress-fighting’, and DNA repair were activated for the cellular adaption coupled with the metabolic activity recovery, probably via recovering the energy production/conversion efficiency and mediating the non-photooxidative stress. Finally, low DO (0.5 mg/L) incubated cells were more susceptible to TiO2 NP exposure and required more time to adapt to and recover from the stress, which was probably due to the stimulation limitation of the oxygen-dependent energy metabolism with a lower oxygen supply. The findings of this study provide new insights into NP contamination control and management adjustments during the BNR process.
