    EU directives on environmental sustainability, such as Directive (EU) 2019/883 of the European Parliament and of the Council of 17th April 2019 on port reception facilities for the delivery of ship generated waste, are stringent. The Commission Communication of 05/23/2013 (Ports: a driver for growth) states that "Port activities cause significant impacts in terms of emissions, noise, water and soil pollution as well as habitat fragmentation" and "The Commission welcomes the initiatives taken by the port sector to promote excellence in environmental management and performance through the publication of guides to good practice". Ports therefore need to adapt to the new requirements also, and above all, in terms of stricter requirements for environmental performance and alternative fuels. Furthermore, according to the European Commissioner for Transport “Maritime transport is a global business, and reducing its emissions requires global solutions. The entry into force of the global sulphur cap is an important milestone for the entire maritime sector; it will contribute to further reduce emissions of harmful air pollutants, directly benefiting cities and communities around the globe, including important ones on our Southern European shores. It also shows that concerted effort from the EU and the IMO, together with strong commitment from the industry can deliver important benefits to the environment and the health of our citizens”. Therefore, due to Europe's historical relationship with the sea (mainly due to commercial reasons) a study has been undertaken on the current offer of European Masters related to seaports. This offer has been analysed according to the educational areas taught (legal, operational, business, management, safety, engineering, ecological, etc.), the language in which they are offered, the duration of the studies, the location of these masters by country and the type of teaching (in person or online). The results have been shown in graphs and it has been seen, among other aspects, that the countries of Southern Europe are the ones that contribute most to teachings related to the maritime sector

    INCAMP project is developing an International Master’s Degree in the Carbon Neutral Management of sport marinas. In this article we present a draft on the distribution of the Master, with main learning materials that will be taught. The content has been divided into paths, modules and subjects, as following: 6 Fundamental modules; 18 Subjects; Practical and a Dissertation. Subjects of the Master has been selected to give the appropriate knowledge to the future students interested in Carbon Neutral Management of sport marinas. INCAMP has been created to meet future skills needs and to enhance the opportunities for cooperation between Higher Education, Vocational Educational Training and Industry, providing opportunities for cooperation among stakeholders as well as the exchange and transfer of knowledge to increase know-how. Throughout the master, students will be taught to understand and investigate the major processes and change drivers which contribute to climate conditions in the earth system at different scales, among them, the understanding of the interdependencies between the grand cycles (water, carbon, nitrogen, phosphorus) in the Sport Marinas Management System. Furthermore, they will analyse the roles played by the biosphere in global and local environmental change: how is it affected by environmental change and how can changes in the biosphere affect global change? A macro-scale view of global biosphere function in Earth history and the global impact of humanity, putting contemporary environmental change into wider context. Human systems of knowledge, values, organization, technology, and behaviour will be examined in relation to environmental change in an evolutionary and social development context. What is the utility of viewing human societies as systems? How do the complexity, diversity, stratification, and resource management strategies of human societies shape their contributions and responses to critical environmental parameters and challenges? The module introduces relevant cognitive, social, economic, and human ecological concepts and theory to understand historical developments in social-ecological systems and address contemporary issues of sustainability and wellbeing in an increasingly populous and globalised society. Specifically, the students will investigate the role of energy systems in causing and mitigating climate change for carbon neutral management of sport marinas. Debates and major trends in the role of technologies, economics, human behaviour, social change and governance in avoiding dangerous anthropogenic climate change

    Diurnal Variation in Mars Equatorial Odd Oxygen Species: Chemical Production and Loss Mechanisms

    Odd oxygen (O, O(¹D), O₃) abundance and its variability in the Martian atmosphere results from complex physical and chemical interactions among atmospheric species, which are driven mainly by solar radiation and atmospheric conditions. Although our knowledge of Mars’ ozone distribution and variability has been significantly improved with the arrival of several recent orbiters, the data acquired by such missions is not enough to properly characterize its diurnal variation. Thus, photochemical models are useful tools to assist in such a characterization. Here, both the Martian ozone vertical distribution and its diurnal variation for equatorial latitudes are studied, using the JPL/Caltech one-dimensional photochemical model and diurnally-variable atmospheric profiles. The chosen equatorial latitude-region is based on the recent and future plans of NASA and other agencies to study this region by different surface missions. A production and loss analysis is performed in order to characterize the chemical mechanisms that drive odd oxygen's diurnal budget and variability on Mars making use of the comprehensive chemistry implemented in the model. The diurnal variation shows large differences in the abundance between daytime and nighttime; and variable behavior depending on the atmospheric layer. The photolysis-driven ozone diurnal profile is obtained at the surface, whilst a sharp decrease is obtained in the upper troposphere at daytime, which originates from the large differences in atomic oxygen abundances between atmospheric layers. Finally, no clear anticorrelation between ozone and water vapor is found in the diurnal cycle, contrary to the strong correlation observed by orbiters on a seasonal timescale

    The Rover Environmental Monitoring Station (REMS) instrument is on board NASA’s Mars Science Laboratory (MSL) Curiosity rover. REMS has been measuring surface pressure, air, and ground brightness temperature, relative humidity, and ultraviolet (UV) irradiance since MSL’s landing in 2012. In Mars Year (MY) 34 (2018) a global dust storm reached Gale Crater at Ls ~ 190°. REMS offers a unique opportunity to better understand the impact of a global dust storm on local environmental conditions, which complements previous observations by the Viking landers and Mars Exploration Rovers. All atmospheric variables measured by REMS are strongly affected albeit at different times. During the onset phase, the daily maximum UV radiation decreased by 90% between sols 2075 (opacity ~1) and 2085 (opacity ~8.5). The diurnal range in ground and air temperatures decreased by 35 and 56 K, respectively, with also a diurnal-average decrease of ~2 and 4 K respectively. The maximum relative humidity, which occurs right before sunrise, decreased to below 5%, compared with prestorm values of up to 29%, due to the warmer air temperatures at night, while the inferred water vapor abundance suggests an increase during the storm. Between sols 2085 and 2130, the typical nighttime stable inversion layer was absent near the surface as ground temperatures remained warmer than near-surface air temperatures. Finally, the frequency domain behavior of the diurnal pressure cycle shows a strong increase in the strength of the semidiurnal and terdiurnal modes peaking after the local opacity maximum, also suggesting differences in the dust abundance inside and outside Gale.Key PointsAtmospheric opacity over Gale Crater was increased by more than 8 times and disturbed all the atmospheric variables measured by REMSREMS data suggest that the nighttime near-surface atmosphere stability was reduced and its water abundance increased during the GDSThe semidiurnal mode peaked after the local opacity maximum, suggesting different dust abundance inside and outside GalePeer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/151294/1/jgre21177_am.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/151294/2/jgre21177.pd

    Summary Eight paternal half-sib families were used to identify chromosomal regions associated with variation in the lactation curves of dairy goats. DNA samples from 162 animals were amplified by PCR for 37 microsatellite markers, from Capra hircus autosomes CHI3, CHI6, CHI14 and CHI20. Milk samples were collected during 6 years, and there were 897 records for milk yield (MY) and 814 for fat (FP) and protein percentage (PP). The analysis was conducted in two stages. First, a random regression model with several fixed effects was fitted to describe the lactation function, using a scale (α) plus four shape parameters: β and γ, both associated with a decrease in the slope of the curve, and δ and φ that are related to the increase in slope. Predictions of α, β, γ, δ and φ were regressed using an interval mapping model, and F-tests were used to test for quantitative trait loci (QTL) effects. Significant (p < 0.05) QTLs were found for: (i) MY: CHI6 at 70-80 cM for all parameters; CHI14 at 14 cM for δ and φ; (ii) FP: CHI14, at 63 cM was associated with β; CHI20, at 72 cM, showed association with α; (iii) PP: chromosomal regions associated with β were found at 59 cM in CHI3 and at 55 cM in CHI20 with α and γ. Analyses using more families and more animals will be useful to confirm or to reject these findings. © 2008 Blackwell Verlag, Berlin.Fil: Roldán, D.L.. Instituto Nacional de Tecnología Agropecuaria.
