description: We present a formal Arabic wordnet built on the basis of a carefully designed ontology hereby referred to as the Arabic Ontology. The ontology provides a formal representation of the concepts that the Arabic terms convey, and its content was built with ontological analysis in mind, and benchmarked to scientific advances and rigorous knowledge sources as much as this is possible, rather than to only speakers' beliefs as lexicons typically are. A comprehensive evaluation was conducted thereby demonstrating that the current version of the top-levels of the ontology can top the majority of the Arabic meanings. The ontology consists currently of about 1,300 well-investigated concepts in addition to 11,000 concepts that are partially validated. The ontology is accessible and searchable through a lexicographic search engine (https://ontology.birzeit.edu) that also includes about 150 Arabic-multilingual lexicons, and which are being mapped and enriched using the ontology. The ontology is fully mapped with Princeton WordNet, Wikidata, and other resources.
Plattdeutsch ist Hobbysprache : Der individuelle Wandel des Sprachgebrauchs Hamburger Niederdeutschsprecher

description: Das Niederdeutsche ist in Hamburg immer seltener Mittel der Alltagskommunikation, trotzdem aber Gegenstand einer lebendigen Regionalkultur. So scheint sich das Niederdeutsche zu einer Sprachform zu wandeln, die wenig Bedeutung im Alttag hat und zunehmend auf organisierte Verwendungskontexte im Freizeitbereich beschränkt ist. In einer qualitativen Studie wird untersucht, wie sich dieser Wandel beim einzelnen Sprecher vollzieht und wie unterschiedliche Verwendungskontexte zusammenhängen. Neben der biographischen Untersuchung des Sprachgebrauchs Hamburger Niederdeutschsprecher und seines Wandels werden dafür die Spracheinstellungen der Sprecher zur Erklärung herangezogen, um mögliche Gründe für das Sprachverhalten eruieren zu können. Es zeigt sich, dass ein Ausbau des Niederdeutschen im kulturellen Bereich sozialsymbolisch motiviert ist und auf die Alltagskommunikation zurückwirkt.

Harnessing sustainability complexity : a strategy to incorporate social factors into engineering education
Creators: name: Matos, Stelvia

Publisher: name: The University of British Columbia
Year: 2015

description: As societal expectations have changed from narrowly focused environmental issues to broader sustainable development concerns, it is vital that future engineers graduate with an understanding of how social impacts may affect or may be affected by their decisions. Drawing on complexity theory and sustainability literature, this paper describes how engineering programs can incorporate a course that will enable graduating engineers to explore the interdependencies among technical, economic, environmental and social dimensions of sustainability. System’s elements and interdependences are identified using modularity, a technique that applies deductive and inductive methods. Using the example of a sustainable lignin-based product we demonstrate how such methods are performed in practice. We then discuss the implications for engineering teaching and propose an integrated sustainability analysis course that focuses on harnessing social factors within sustainability complexity, by seeking them out and exploiting interdependencies. This will prepare future engineers to work on a more realistic scenario, and more broadly explore new ideas and possible solutions.

description: This presentation describes a project to embed a repository system (based on Fedora) within the complex, experimental processes of a number of researchers in biophysics and structural biology.  The project is capturing not just individual datasets but entire experimental workflows as complex objects, incorporating provenance information based on the Open Provenance Model, to support reproduction and validation of published results. The repository is integrated within these experimental processes, so that data capture is as far as possible automatic and invisible to the researcher. A particular challenge is that the researchers’ work takes place in local environments within the department, entirely decoupled from the repository. In meeting this challenge, the project is bridging the gap between the “wild”, ad hoc and independent environment of the researchers desktop, and the curated, sustainable, institutional environment of the repository, and in the process project crosses the boundary between several of the pairs of polar opposites identified in the call.

PEM fuel cell

description: Spatially resolved measurements on PEM fuel cells have been performed for at least two decades [1] and this measurement technique has provided better understanding of the coupled processes inside the cell. Especially, variations along the channel (ATC), such as gas concentrations, membrane humidification, water saturation and others can be depicted and their impact on the overall cell performance can be analysed. At Fraunhofer ISE, we developed the next version of our segmented ATC PEM fuel cell with 50 cm² active area divided in 25 segments along the gas channel. Together with a new multichannel characterisation system, fast voltage / current and impedance measurements are available. 3D CFD Models for PEM fuel cells are also developed and improved since more than 20 years [2] and are currently available most commercial CFD software codes; they can provide more detailed insights on the local effects in each dimension like channel-rib variations or through-plane gradients in the GDL and electrodes. But they come with relatively long simulation time in the range of some hours for steady-state simulations of single cell parts or even days for dynamic or larger cell / stack simulations. To provide more flexible and faster results that can help the experimenter before or even during the experiments, e.g. under which conditions or in which segment, flooding, drying or concentration issues can be expected, we developed a dynamic ATC model that calculates mass and heat balance in a discrete number of coupled segments (e.g. 25) along the two gas channel sides. It uses simplified kinetics using a Tafel approach, water transport through the membrane and heat transfer between the gas channels, solids and surrounding. This work compares and analyses specially resolved measurement results from the ATC fuel cell together with simulation results from a commercial CFD-Code (AVL FireM) and results from our simplified ATC model. It shows computation times, under which conditions and for which purposes, the simplified model approach is appropriate enough for predicting local variations and which limitations have to be considered. Limits in operating conditions like cell voltage, stoichiometry and humidity are discussed in which local effects like channel-rib-differences or through-plane humidity variations can or cannot be neglected and shows possible advantages and drawbacks of the simplification.

G-quadruplex formation in mouse macrophages changes the immune response to bacterial infection
Creators: name: Kastl, Melanie
Publisher: name: Universitäts- und Landesbibliothek Bonn
Year: 2024
Subjects: subject: ddc:610

description: G-quadruplexes (G4s) are stable secondary structures that form in guanine-rich regions of DNA and RNA. Guanines bind via Hoogsteen hydrogen bonding and form G tetrads that stack upon each other and become stabilized by a cation in the center. Nowadays it is proven that G4s form in vivo and influence a variety of biological processes, including transcription, translation, replication, and telomere maintenance. More than 700,000 sites in the human and mouse genomes have the potential to form a G4. Since G4s are enriched in oncogenic promoters, they are targeted in cancer therapy. The contribution of tumor-associated macrophages (TAMs) in the tumor environment has been controversially discussed. Therefore, linking cancer and inflammation and analyzing the role of G4s in macrophages is an emerging research question.
 The here presented doctoral thesis provides a detailed analysis of the role of G4s in mouse macrophages during bacterial infection mimicked by lipopolysaccharide (LPS). It was shown that G4s form in macrophages and can be stabilized by the G4-specific ligand pyridostatin (PDS). While the key macrophages function of phagocytosis was unaffected by G4 stabilization, G4 formation was shown to reduce the immune response-related cytokine expression and secretion. These transcriptome-wide changes affecting the immune response to bacteria are modulated by changes in the activity of the transcription factor NF-κB, a master regulator in orchestrating host defense. ATAC-Seq to map the chromatin landscape revealed that G4 stabilization modulates the accessibility of transcription start sites which could explain the transcriptomic changes.
 The data presented here provide the basis for a novel role of G4s in the immune response to bacteria in macrophages. These findings open the possibility to discuss G4s as a drug target to control the immune response, for example during an endotoxic shock (sepsis) induced by exposure to LPS.

description: Using pre-trained transformer models such as BERT has proven to be effective in many NLP tasks. This paper presents our work to fine-tune BERT models for Arabic Word Sense Disambiguation (WSD). We treated the WSD task as a sentence-pair binary classification task. First, we constructed a dataset of labeled Arabic context-gloss pairs (~167k pairs) we extracted from the Arabic Ontology and the large lexicographic database available at Birzeit University. Each pair was labeled as True or False and target words in each context were identified and annotated. Second, we used this dataset for fine-tuning three pre-trained Arabic BERT models. Third, we experimented the use of different supervised signals used to emphasize target words in context. Our experiments achieved promising results (accuracy of 84%) although we used a large set of senses in the experiment.

description: The processing of the Arabic language is a complex field of research. This is due to many factors, including the complex and rich morphology of Arabic, its high degree of ambiguity, and the presence of several regional varieties that need to be processed while taking into account their unique characteristics. When its dialects are taken into account, this language pushes the limits of NLP to find solutions to problems posed by its inherent nature. It is a diglossic language; the standard language is used in formal settings and in education and is quite different from the vernacular languages spoken in the different regions and influenced by older languages that were historically spoken in those regions. This should encourage NLP specialists to create dialect-specific corpora such as the Palestinian morphologically annotated Curras corpus of Birzeit University. In this work, we present the Lebanese Corpus Baladi that consists of around 9.6K morphologically annotated tokens. Since Lebanese and Palestinian dialects are part of the same Levantine dialectal continuum, and thus highly mutually intelligible, our proposed corpus was constructed to be used to (1) enrich Curras and transform it into a more general Levantine corpus and (2) improve Curras by solving detected errors.

description: As the Internet of Things (IoT) technology is being deployed, the demand for radio spectrum is increasing. Cognitive radio (CR) is one of the most promising solutions to allow opportunistic spectrum access for IoT secondary users through utilizing spectrum holes resulting from the underutilization of frequency spectrum. A CR needs to frequently sense the spectrum to avoid interference with primary users (PUs). Compressive spectrum sensing techniques have been gaining increasing interest in wideband spectrum sensing, as they reduce the need for high-rate analog-to-digital converters, reducing the complexity and energy requirements of the CR. In order to enhance spectrum sensing performance, researchers proposed to incorporate PU spectrum usage information into the process of spectrum sensing. Spectrum usage information can be obtained through pilot signals, geo-locational databases or through evaluation of previous spectrum sensing results. In this paper, we are studying the effects of compressive sensing parameters namely compression ratio, sensing period, and sensing duration on the estimation of primary user behavior statistics. We achieved an accurate estimation of the primary user's behavior while saving 40% of the sampling rate by using compressive spectrum sensing compared to traditional spectrum sensing with Nyquist rate sampling.

description: The PARADeS project focused on Ghana’s national flood disaster risk reduction and management strategy by investigating existing flood risk and mechanisms for disaster management, governance-policy, human-water interaction, and development of possible future scenarios and feasible and sustainable measures.
 Three case study areas with different types of flooding were identified and chosen in a participatory flood risk-based process. These are including the catchments Odaw in Accra (pluvial, fluvial and coastal floods), Aboabo in Kumasi (pluvial and fluvial floods), and the White Volta (fluvial floods).
 The project used innovative socio-technical and participatory approaches and tools that combines research, development, and institutional strengthening activities. It integrated diverse information, local knowledge and data sources and was developed collaboratively with stakeholder scenarios and socio-technical tools in order to support coherent decision-making processes. A key aspect was analysing different scenarios of flood hazards, investigating and modelling cascading risk effects regarding critical infrastructure, and an assessment tool to identify flood risk at a household level, the FLOODLABEL Ghana. All processes and working steps are realized using interdisciplinary and participatory approaches together with Ghanaian stakeholders.
 The end products are strengthening institutional and citizens’ capacity through a series of activities on societal awareness and training of specialists, decision, and policymakers. Technologically, the project has produced a set of decision support tools (Flood Information Systems, FLOODLABEL Ghana, etc.) to effectively disseminate vital information to citizens, researchers, and decision makers to respond and mitigate the impact of flooding.
 In pursuit of sustainable development in FDRM measures, we disseminated the outcomes and products, including technical tools, through reports and scientific publications. Additionally, we developed training materials tailored for students, experts, and decision-makers.
A new program in sustainable engineering : a platform for integrating research and service into the classroom through global engagement

description: Currently 2.5 billion people, over one third of the Earth’s population, are affected by water scarcity and are without sanitation. The majority of humanity is concentrated in coastal communities: approximately half of the world’s population lives within 200 kilometers of a coast. In many developing countries, raw wastewater is discharged into coastal waters without being treated, in the belief that these discharges do not significantly affect the environment. In reality, these contaminants not only threaten human health, but also often contribute to the loss of marine animals which local peoples often rely on for food and income. In the future, continuing population growth and economic development will increase the demand for water and the severity of pollution. There is a clear and overwhelming need for sanitation and water purification in developing coastal communities, but it is not afforded by conventional, energy-intensive and chemically-intensive water treatment or fossil-fuel-based energy systems. In high-poverty equatorial coasts, the stable temperatures, steady winds, and predictable solar input greatly facilitate sustainable practices for water treatment and energy production. We have recently begun to develop a new cross-disciplinary program in Sustainable Engineering at Penn State that empowers coastal communities in the Caribbean to improve their quality of life and protect their natural resources. In this program, senior-level engineering courses train undergraduate and graduate students to design and deploy ecologically-designed wastewater treatment plants with renewable energy systems in collaboration with faculty-led research teams and community participants. These courses are strategically designed to be training and recruitment tools to help prepare the local student chapter of Engineers Without Borders (EWB) for the project, and to provide students at all levels with challenging, immersive, hand-on experiences that augment their research and education in sustainability. This work is significant because it is one of the first international, multi-disciplinary programs in Sustainable Engineering in North America, and utilizes a student outreach organization (EWB) to mobilize the resulting efforts to engage developing coastal communities with the assistance of practicing engineers. The longevity of this program is supported through cross-disciplinary research, course development, and mentoring of EWB projects containing interdisciplinary, multi-component systems. Future partnerships in the areas of wind energy, coral reef resilience, food systems science, economic development, and eco-tourism are planned to further enhance the program.
Do the big sustainability challenges lie in the economic and social domains and does engineering education need to engage more with these?
Creators: name: Fitzpatrick, John J.
Publisher: name: The University of British Columbia
Year: 2015

description: Engineering education is mainly a technical education. However, in the context of the sustainability of the human species, it could be argued that graduate engineers entering the workplace and applying their technical education may be only accelerating humanity towards unsustainability and societal collapse. The rationale being that engineering graduates mainly enter industry and the private sector which is dominated by the neo-classical economic paradigm and short term pursuit of economic growth and profit to the detriment of the sustainability of natural systems that are underpinning the survival and flourishing of humanity. The author has been teaching engineering students for nearly 19 years in technical subjects and later on in sustainability and environmental protection. Over the last few years, he has had the niggling feeling that he, and other engineering educators, are complicit in the formation of engineers that may only accelerate humanity towards unsustainability. They mean well and truly believe that they are doing good for society. There may be good in the short term, but it is unsustainable and ultimately bad for society in the longer term. This paper briefly explores the impact of engineering on environmental sustainability in the current dominant neo-classical economic paradigm. It questions if engineering educators are producing engineers that are accelerating humanity along an unsustainable path. Even though technology and engineering are important drivers in trying to move humanity towards an environmentally sustainable paradigm, the paper constantly tries to suggest that maybe the most important levers and challenges lie in the economic and social domains. Short case-studies of energy efficiency, the experience of the industrialist Ray Anderson and the authors own reflection of teaching chemical engineering students are used to highlight this. Engineering / technological innovation is not enough and is often used and counteracted by the rebound effect and the current dominant neo-classical economic paradigm. The paper discusses what engineering educators can do to produce sustainability informed engineers who are able to engage with the economic and social dimensions of sustainability. Some suggestions for engaging engineering students with the economic and social dimensions of environmental sustainability are provided. Engineers must somehow find ways, not just to influence technological levers (which are very important) but also to influence economic and social levers so that changes in economic and social behaviours can complement and facilitate technological change in moving humanity to an environmentally sustainable paradigm.

description: Majority of speech signals across different scenarios are never available with well-defined audio segments containing only a single speaker. A typical conversation between two speakers consists of segments where their voices overlap, interrupt each other or halt their speech in between multiple sentences. Recent advancements in diarization technology leverage neural network-based approaches to improvise multiple subsystems of speaker diarization system comprising of extracting segment-wise embedding features and detecting changes in the speaker during conversation. However, to identify speaker through clustering, models depend on methodologies like PLDA to generate similarity measure between two extracted segments from a given conversational audio. Since these algorithms ignore the temporal structure of conversations, they tend to achieve a higher Diarization Error Rate (DER), thus leading to misdetections both in terms of speaker and change identification. Therefore, to compare similarity of two speech segments both independently and sequentially, we propose a Bi-directional Long Short-term Memory network for estimating the elements present in the similarity matrix. Once the similarity matrix is generated, Agglomerative Hierarchical Clustering (AHC) is applied to further identify speaker segments based on thresholding. To evaluate the performance, Diarization Error Rate (DER%) metric is used. The proposed model achieves a low DER of 34.80% on a test set of audio samples derived from ICSI Meeting Corpus as compared to traditional PLDA based similarity measurement mechanism which achieved a DER of 39.90%.

description: A high content of flavonoids in beverages is desirable not only due to their beneficial health effects, but also due to their ability to protect fruit juices from oxidation. However, food processing has a profound effect on these phytochemicals, with the further loss of most of their beneficial properties. For this reason, five flavonoids (catechin, rutin, hesperidin, quercetin and apigenin) were analyzed by HPLC in accordance to Kelebek et al. (2015) in a fruit juice-stevia beverage before and after pulsed electric fields (PEF), high voltage electical discharges (HVED) and ultrasounds (USN) treatments at two equivalent energy inputs. Catechin and hesperidin were the mayor phenolic compounds. For this two flavonoids, along with quercetin, PEF and USN treatments resulted in a significant increase compared to untreated beverage. By contrast, rutin decreased after PEF, HVED and USN treatment. The highest decrease was obtained when the beverage was treated by HVED at 256 kJ/kg. Apigenin content was far much lower in the USN treated beverage, as this compound may be severely affected by the cavitation phenomena. Results obtained highlight that individual flavonoids undergo different changes immediately after HVED, PEF and USN treatments, whereas others remain unchanged or are even enhanced.

description: Naringenin is a chiral flavanone distributed especially in citrus fruit, in which is present as a mixture of chiral isomers. Among the numerous biological properties attributed to this compound, we have focused the investigation on the antioxidant and anti-inflammatory activities1. Previous results showed the in vitro enantio-selective anti-inflammatory capacity of naringenin, highlighting the higher capacity of (R)-enantiomer to inhibit TNF-α and IL-6 secretion2. The aim of the present research is to evaluate the potential molecular mechanism of (R)- and (S)-enantiomers, which could explain their antioxidant and anti-inflammatory activities. We focused our attention on the regulation of epigenetic mechanisms, studying the expression levels of two miRNAs and relative mRNA targets, involved in the modulation of antioxidant and anti-inflammatory responses. Caco-2 cells were treated with increasing subtoxic concentrations of (R)- and (S)-enantiomers. The expression levels of the selected miRNAs and related mRNAs were determined by Real-Time PCR, highlighting an influence of the two enantiomers on their expression levels. Our results suggest that both enantiomers influence miRNA expression levels in a very similar way. Thus, the epigenetic regulation could be at the basis of enantiomeric naringenin mechanism of action.

description: Objectives: Previous data show that a phenolic-enriched extract from Hibiscus sabdariffa, which contains quercetin, might ameliorate metabolic disturbances associated to obesity. Here we investigate the uptake and metabolism of quercetin and its metabolite quercetin-3-glucuronide by hypertrophied 3T3-L1 adipocytes and their effect on oxidative stress.

 Methodology: To study the uptake of compounds by adipocytes, cytoplasmic fractions were collected at different time points (0, 3, 6, 12 and 18 h) after incubation and analyzed by HPLC-DAD-ESI-TOF. Generation of intracellular reactive oxygen species (ROS) were measured using the fluorogenic dye 2',7'-dichlorodihydrofluorescein diacetate (H2DCFDA).

 Results: Quercetin reached the maximum concentration in the cytoplasm after 3 hours of incubation and it was 20-fold higher respect to its glucuronic derivative, whose uptake was slower reaching its highest concentration at the final time point (18 hours). Furthermore, both compounds were detected in the cytoplasm as products of cellular metabolism. A correlation was found between the ROS generation and the behavior of the uptake and metabolism of the compounds.

 Conclusion: Quercetin and quercetin-3-glucuronide are absorbed by adipocytes, so it is postulated that these polyphenolic compounds would be responsible for the antioxidant effect of Hibiscus sabdariffa extract in hypertrophied adipocytes.

description: Effective Human-Robot Interaction (HRI) is crucial for future service robots in aging societies. Existing solutions are biased toward only well-trained objects, creating a gap when dealing with new objects. Currently, HRI systems using predefined gestures or language tokens for pretrained objects pose challenges for all individuals, especially elderly ones. These challenges include difficulties in recalling commands, memorizing hand gestures, and learning new names. This paper introduces NVP-HRI, an intuitive multi-modal HRI paradigm that combines voice commands and deictic posture. NVP-HRI utilizes the Segment Anything Model (SAM) to analyze visual cues and depth data, enabling precise structural object representation. Through a pre-trained SAM network, NVP-HRI allows interaction with new objects via zero-shot prediction, even without prior knowledge. NVP-HRI also integrates with a large language model (LLM) for multimodal commands, coordinating them with object selection and scene distribution in real time for collision-free trajectory solutions. We also regulate the action sequence with the essential control syntax to reduce LLM hallucination risks. The evaluation of diverse real-world tasks using a Universal Robot showcased up to 59.2\% efficiency improvement over traditional gesture control, as illustrated in the video https://youtu.be/EbC7al2wiAc. Our code and design will be openly available at https://github.com/laiyuzhi/NVP-HRI.git.

description: Cocoa bean shells (CBS) is one of the main by-products of the cocoa roasting process, which represents 12% of total weight after the husking and grinding1. CBS is a potential source of dietary fibre and polyphenols recognized as dietary factors responsible for potential beneficial effects on human health.
 The aim of this study was to evaluate the stability and bioaccessibility of phenolic compounds and the changes on the antioxidant activity of enriched ice cream during gastrointestinal digestion.
 CBS flour was added to ice cream at different concentration (2%, 4%, 6% and 8%) and the total phenolic content (TPC), total flavonoids, tannins and radical scavenging activity  (DPPH) were evaluated during in vitro digestion at different steps of digestion (oral, gastric and duodenal).
 After in vitro digestion total flavonoids and tannins increase slightly and TPC increase up to 50% compared to control before digestion. The radical scavenging activity of ice cream containing cocoa bean shell increases up to 25% compared to ice cream before digestion.
The results suggested that CBS may be a promising functional ingredient to producing highly nutritive value ice cream minimizing the volume of agro-industrial wastes.

description: The scaling of fluctuations in the distribution of ground-state energies or costs with the system size N for Ising spin glasses is considered using an extensive set of simulations with the Extremal Optimization heuristic across a range of different models on sparse and dense graphs. These models exhibit very diverse behaviors, and an asymptotic extrapolation is often complicated by higher-order corrections. The clearest picture, in fact, emerges from the study of graph-bipartitioning, a combinatorial optimization problem closely related to spin glasses. Aside from two-spin interactions with discrete bonds, we also consider problems with Gaussian bonds and three-spin interactions, which behave differently to a significant degree.

description: Oxidation reactions occurring on food surface are one of the main causes of deterioration of fresh and processed food products. Packaging is one of the most important tool to protect foodstuff from these oxidative processes. This work aims at developing innovative films by coating a polymer surface activated by plasma with a layer-by-layer structure made of chitosan and tannin extract from Galla chinensis (GT). Experiments were performed using three different polymeric films, which were coated with GT solutions at different concentrations (1, 3 and 5%). Oxygen transmission rate (OTR), thermal behaviour, antioxidant activity (DPPH) and total phenolic content (TPC) of active films were evaluated. The OTR values were reduced to one third compared to untreated films. The m-ATR spectra of the active films suggest that some interactions occurred between chitosan and the tannin extract. The new films added of tannin extract (TPC values between 0.5 and 5.4 mg GAE/dm2  of film) showed a radical scavenging activity with values ranged between 10.5 and 55.8 μmol TE/dm2 of film. The obtained results suggest that the active films produced could be exploited for developing active packaging suitable in the food industry to extend the shelf life of foodstuffs.

description: With local density approximation + Hubbard $U$ (LDA+$U$) calculations, we show that the ferromagnetic (FM) insulating state observed in tensile-strained LaCoO$_3$ epitaxial thin films is most likely a mixture of low-spin (LS) and high-spin (HS) Co, namely, a HS/LS mixture state. Compared with other FM states, including the intermediate-spin (IS) state (\textit{metallic} within LDA+$U$), which consists of IS Co only, and the insulating IS/LS mixture state, the HS/LS state is the most favorable one. The FM order in HS/LS state is stabilized via the superexchange interactions between adjacent LS and HS Co. We also show that Co spin state can be identified by measuring the electric field gradient (EFG) at Co nucleus via nuclear magnetic resonance (NMR) spectroscopy.
Are Finns walking the talk? : examining the national collaboration process on engineering education for sustainable development five years later

description: In 2009, the National Collaboration Group for Finnish Engineering Education published a proposal for action on sustainable development (SD). The aim of this paper is to analyze how the three main universities providing engineering education have fulfilled their commitments. The study consists of interviews with key stakeholders supplemented with the analysis of documented material. It is argued that the studied universities are now committed to SD in their strategies. However, a lot of work remains to be done before the strategies are implemented and SD is integrated to all degree programmes. Recommendations for the next steps are presented.

description: In the current „industrial“ world, the „natural“ nutraceuticals of plant origin are increasingly popular as dietary supplements, herbal remedies or fitness enhancers, preferred by many in comparison with the „chemical drugs“, produced by the pharmaceutical industry. Alas, one well-known disadvantage of the drugs and extracts based on natural products is their potential variability, which may make any of their effects irreproducible or unreliable.
 We demonstrate this variability on the preparations based on the sea-buckthorn (Hippopae rhamnoides), which is a rather popular source of unsatorated fatty acids, rich in vitamins, containing also a plethora of polyphenolics and other potentially biologically active coumpounds. Analytical data from literature and from various commercially available preparates of „oil from berries“ were compared. Both the macroscopic parameters of the preparations, and the details of their composition vary rather widely, reflecting not only biological (and geographic) variablity of the species, but possibly also the influence of the used extraction method and of the final adjustment in the commercial preparate.
 This variablity is reflected also in the differing stability during storage and it may quite strongly influence the potential biological effects and benefits connected with the use ot the sea-buckthorn-based nutraceuticals.

description: We consider Fano manifolds admitting an algebraic torus action with general orbit of codimension one. Using a recent result of Datar and Szekelyhidi, we effectively determine the existence of Kahler-Ricci solitons for those manifolds via the notion of equivariant K-stability. This allows us to give new examples of Kahler-Einstein Fano threefolds, and Fano threefolds admitting a non-trivial Kahler-Ricci soliton.
