Since their introduction by James Dixon in 2010,data lakes get more and more attention,driven by the promise of high reusability of the stored data due to the schema-on-read *** on this idea,several additional requirements were discussed in literature to improve the general usability of the concept,like a central metadata catalog including all provenance information,an overarching data governance,or the integration with(high-performance)processing *** the necessity for a logical and a physical organisation of data lakes in order to meet those requirements is widely recognized,no concrete guidelines are yet *** most common architecture implementing this conceptual organisation is the zone architecture,where data is assigned to a certain zone depending on the degree of *** paper discusses how FAIR Digital Objects can be used in a novel approach to organize a data lake based on data types instead of zones,how they can be used to abstract the physical implementation,and how they empower generic and portable processing capabilities based on a provenance-based approach.

LAS degradation rate in Donghu Lake water under aerobic was much faster than under anaerobic condition . The half life of LAS in aerobic and anaerobic environment was 3.2 days and 57 days, respectively . The degradation rate at 25-27℃was approximately 20 times higher than that at 1.5-3.5℃.In a laboratory model aquatic ecosystem, two stages of bioconcentration in fish , daphnia and snail were observed . The first stage , on second day exposure , resulted from accumulation of intact LAS , and the second stage , on 16th day exposure , was due to metabolites . The bioconcentration factor (BCF) of LAS was extremely low in the muscle of hybrid carp (0.64), but rather high (2485) in the gall bladder .

Freshly-cleaved HOPG crystals were irradiated with Ni, Zn, Xe and U ions of specific energy 11.4 MeV/u at the linear accelerator UNILAC and with Ne, Cr, Zn, Xe ions (1.4 MeV/u) at the high-charge injector HLI, both facilities are in operation at GSI, Darmstadt. The irradiation with Fe ions was performed at HIRFL (22 MeV/u) of IMP, Lanzhou. All irradiations were performed at room temperature and under beam incidence normal

Poultry production has important economic, social and cultural benefits and plays a significant role in family nutrition in developing countries. In most tropical countries it is based mainly on scavenging production systems, which makes substantial contributions to household food security throughout the developing world. All over the developing world, these low-input and low-output poultry-husbandry systems are an integral component of the livelihoods of most rural, peri-urban, and some urban households and are likely to continue to meet this role for the foreseeable future. Although the contributions of chicken farming to household food security and income as well as its potential contribution to the income of rural communities are known, chicken production is practiced very little in Somaliland. Therefore, the purpose of this project was to carry out a baseline study on the potential of chicken production (eggs and meats) in Somaliland and its existing chain gaps in order to identify whether chicken production could be a successful income source for women and boost female economic activity in the project areas of Saaxil, MaroodiJeex and Togdheer. The result from this assessment showed that rural chicken production was a women-related activity that helped them to be the sole decision-makers and also users of the benefits regarding chicken and chicken products. The main purposes for keeping chicken were egg production for income generating, home consumption and meat provision. The major constraints for rural poultry keeping were the lack of extension and veterinary services, predators, poor housing, poor breeds, and lack of financial services among others. Women in all the selected villages made remarkable contributions to the local chicken production system. The result of the assessments showed that indigenous poultry value chain consisted of producers, collectors/retaileres, shops and consumers/restaurents. However, the absence of processors along the chain means

Carbon materials have been widely used as electrodes, but the mechanistic roles are still not clear due to the complexity of the carbon surface chemistry. Herein we clarify that intrinsic material properties of carbon have to be activated by extrinsic factors. Pure carbon has no catalytic activity when used as electrode for electrocatalytic water oxidation. The evolution of oxygen functional groups on the carbon surface with increasing potential and the subsequent formation of real active sites with iron impurities from the electrolyte have been confirmed. These in-situ formed active sites protect the carbon from deep oxidation. This unprecedented finding not only provides insight into the dynamic evolution of carbon electrode surface chemistry and raises awareness of the need for detailed surface analysis under operando conditions, but also suggests a direction for the development of scalable and high-performance carbonbased electrode systems for various electrochemical applications.
