    Abstract Due to the possibility of using cultivated soils as atmospheric carbon sinks, studies are being carried out worldwide to estimate the potential of carbon sequestration in agricultural areas. In the Pampas, the soil organic carbon (SOC) stock has been calculated at regional scale but its temporal dynamic is unknown. Using information on land cover, yield trends of the main crops, SOC stocks at year 2008 and the AMG model validated with local experiments, the SOC balance of croplands in the Pampas was calculated between 2008 and 2050. Carbon inputs from grain crops were calculated using results of experimental field networks carried out in the Pampas and local coefficients were calculated for the effects of the cultivation of pastures and the adoption of cover crops on SOC. Between 2008 and 2025, the SOC balance of cultivated soils changed from slightly negative to nearly steady state as result of increases in yield and higher carbon inputs. If current rotations are maintained and the rate of increased crop productivity does not stagnate, the Pampas will become an atmospheric carbon sink between 2025 and 2050 as a result of the higher carbon inputs of crops. The adoption of cover crops will improve the balance of SOC but the main tool for sequestering carbon in soils is the replacement of part of the large area cultivated with soybean by greater biomass crops such as corn or the double crop in a year wheat/soybean. Soybean replacement will almost double the carbon sequestration rate compared to the current management and allow attaining the 4‰ goal around 2050. Pampean croplands could represent a sink for atmospheric carbon in the coming years and the management applied can determine how important the sink would be.

    Abstract With the trend towards promoting personalised medicine (PM), the application of pharmacogenetics and pharmacogenomics (PGx) is of growing importance. For the purposes of clinical trials, the inclusion of PGx is an additional tool that should be considered for improving our knowledge about the effectiveness and safety of new drugs. A search of available clinical trials containing pharmacogenetic and PGx information was conducted on ClinicalTrials.gov. The results show there has been an increase in the number of trials containing PGx information since the 2000 s, with particular relevance in the areas of Oncology (28.43%) and Mental Health (10.66%). Most of the clinical trials focus on treatment as their primary purpose. In those clinical trials entries where the specific genes considered for study are detailed, the most frequently explored genes are

    Abstract An increasing share of dispatchable renewable generation is required to achieve energy decarbonisation goals and ensure a reliable supply to power grids. Concentrating solar power (CSP) plants hybridised with biomass boilers are promising alternatives to replace part of the peaking and baseload power generated from fossil fuel-based systems. This paper includes data related to the design variables, equations, valuation parameters and detailed results that support the research article "Market profitability of CSP-Biomass hybrid power plants: Towards a firm supply of renewable energy." The profitability assessment is based on integrating the hourly variation of electricity prices in the Iberian day-ahead market (MIBEL) to the results of the techno-economic model through a novel economic metric named

  6. Article ; Online: Market profitability of CSP-biomass hybrid power plants: Towards a firm supply of renewable energy

    Abstract CSP-biomass hybrid power plants are promising options for displacing electricity from flexible fossil systems and increasing the share of dispatchable renewable energy in power grids. However, they are investment-intensive technologies whose competitiveness in electricity markets is still uncertain. This paper explores for the first time the profitability of CSP-biomass hybrid systems, assuming their participation as price-taking technologies in the Iberian day-ahead electricity market. For this purpose, a new economic evaluation metric called the Profitability Factor is proposed to extend the scope of the levelized cost of electricity (LCOE) by including the variability of market electricity prices. Besides, a stochastic approach integrating uncertainty related to investment costs, electricity prices and biomass costs through Monte-Carlo sampling methods has been applied. Results show that CSP-biomass schemes have up to 33% probability of being profitable in the electricity market before considering external financial support. High biomass share (approx. 76%) leads to a profitability increase of up to 0.11 USD/kWh (median value) compared to an equivalent CSP stand-alone plant. In addition, best-performing hybrid configurations would require a maximum add-in tariff between 0.040 and 0.071 USD/kWh (95% probability) to achieve grid parity. The resulting external financial support is significantly lower than those set through Power Purchase Agreements for the first generation CSP stand-alone plants (still in operation). Thus, CSP-biomass hybrid plants could provide flexibility and other services to power grids, which, if valued in the electricity market, would further increase the technology's competitiveness.

    Abstract For decades, there has been debate about the possibility that organic farming can feed the world’s population. The most recent studies, analyzing the yields of individual crops, show a yield gap between organic and conventional farming. The rotations and the intensity of soil use are also different between systems and the impact of this factor on productivity has not been assessed. A meta-analysis of the yield data of organic and conventional crops and the intensity of soil use (years with harvest crop in relation to rotation duration) was carried out using studies published in peer-reviewed journals. The yields under organic farming were on average 25% lower than the conventional ones, reaching a yield gap of 30% for cereals. The intensity of soil use was also lower in organic systems, the size of the reduction depending on the type of study: field experiments (7%) or on-farm studies (20%). Combining the yield gap with the reduction in the number of crops harvested in the rotation, a productivity gap of 29% to 44% was estimated depending on the type of crops included in the rotation. These results show that the productivity gap is greater than the yield gap between organic and conventional farming.

    Abstract The share of variable renewable energy (VRE) is forecasted to increase in the energy sector to meet decarbonization targets and/or reduce their dependence on fossil fuels. The modeling of future power system scenarios is crucial to assess the role of different flexibility options, including low-carbon technologies. The data presented here support the research article "The role of energy storage in Great Britain's future power system: focus on hydrogen and biomass". These data include updated parameters, inputs, equations, biomass resource potential and biomass demand to balance bio-power and bio-hydrogen requirements. The Future Renewable Energy Performance into the Power System Model (FEPPS), a rule-based model that includes flexibility and stability constraints, has been used, and the hourly results of future scenarios by 2030 and 2040 are provided. Researchers, policymakers, and investors could use this paper as these data provide insights into the role of different technologies (including hydrogen and biomass) in power generation, system flexibility, decarbonization and costs.

    Abstract GPCRs receive signals from diverse messengers and activate G proteins that regulate downstream signaling effectors. Efficient signaling is achieved through the organization of these proteins in membranes. Thus, protein-lipid interactions play a critical role in bringing G proteins together in specific membrane microdomains with signaling partners. Significantly, the molecular basis underlying the membrane distribution of each G protein isoform, fundamental to fully understanding subsequent cell signaling, remains largely unclear. We used model membranes with lipid composition resembling different membrane microdomains, and monomeric, dimeric and trimeric Gi proteins with or without single and multiple mutations to investigate the structural bases of G protein-membrane interactions. We demonstrated that cationic amino acids in the N-terminal region of the Gαi

    Abstract The transfer matrix method is considered to obtain the fundamental properties of 1D Dirac-like problems. The case of 1D problems in monolayer graphene is addressed. The main characteristics of the transfer matrix are analyzed, contrasting them with the ones corresponding to 1D Schrödinger-like problems. Analytic expressions for the transmission coefficient and bound states are obtained. The continuity between bound states and states of perfect transmission is demonstrated in general, and in particular showed for the case of single electrostatic barriers. These findings in principle can be extended to 2D materials with Hamiltonian similar to monolayer graphene such as silicene and transition metal dichalcogenides.
