title: CO2 refrigeration technology: possible innovations.

description: CO2 as a working fluid in refrigeration and heat pumping systems is currently entering more and more sectors, due to its unique characteristics and safety advantages. As a non-flammable refrigerant, there are very few restrictions to apply this natural working fluid in domestic and industrial applications. An important issue, when introducing CO2 refrigeration technology, is to understand that the thermodynamic and fluid dynamic properties are different compared to conventional refrigerants. To enable energy efficient system configurations, just a refrigerant drop-in design approach will fail. The main advantages of applying CO2 as a working fluid are the high working pressure level, excellent heat transfer properties, the ability to achieve high temperature lifts, and high compressor efficiencies enabling energy efficient and safe installations. The integration of ejectors in various configurations opens for additional functionalities. Based on the description of state of the art system configurations, possible innovative system improvements are described, such as ejector-supported AC production or ejectors enabling additional evaporation temperature levels. Understanding of potential design improvements and their impact to cost and energy demand are the first step to get new technology developed and to create a market interest.

title: Presentation of the first combined CO2 heat pump, air conditioning and hot tap water system for a hotel in Scandinavia

description: Hotels are high-energy consuming buildings with numerous demands for heating and cooling at several temperature levels. The heating load is largely dominated by hot water production (28%: NVE, 2016) in order to meet the hot water consumption of the many guests. The current practice is to have several independent heating and cooling systems. Most of the hotels in northern Europe use thermally inefficient methods, such as electric boilers or district heating stations, which simultaneously provide high temperature heat for tap water and a high temperature space heating circuit. Currently, CO2 technologies are widely used in Scandinavia at an industrial scale thanks to their high efficiency in cold climates. The first combined CO2 heating, air conditioning and hot tap water system with an integrated thermal storage for a hotel is installed (2018) in Norway (Trondheim) and is presented in this paper. The working principal of the system is clearly described in this work and data obtained from the first test campaigns are presented. The heat pump has an installed capacity of 280 kW. If cooling is needed, chilled water for AC cooling is used as a heat source. Heat is rejected to two different circuits in the gas cooler in order to achieve high and medium temperature levels according to the setpoint of the different heating applications. The tap water system is mainly composed of a 6 m3 buffer tank storage unit, in order to ensure continuous production of hot water to covers the peak demand period. Preliminary results show significant energy savings (59-68%) and peak power reductions (15-45%).

title: Improved oil level detection and equalization system for CO2 high pressure shell hermetic rotary compressor.

description: The development of hermetic CO2 compressors provided the economical ability to design transcritical systems that are efficient, reliable and cost effective. Moreover, if combined with variable speed technology, these compressors are able to provide a broad rotor speed working range, low noise and low vibrations. In order to ensure a reliable operation of these systems, a key feature is a proper oil management accomplished via oil level monitoring and equalization among the devices. This paper presents an improved method for oil level control in a high-pressure shell hermetic rotary compressor rack for CO2 vapour compression cycles. The solution is based on the temperature variation measured during the fluid expansion from the compressor shell to the suction line through a modulating throttling device. Thanks to a dedicated logic, the modulation of the valve opening degree allows to perform both the detection and the equalization of the oil levels among all the rack compressors, increasing reliability. Unlike other available methods, the oil level control is achieved by taking into account the current system working conditions in terms of pressures, temperatures and compressor rotor speeds, minimizing the required monitoring time and the bypassed flow rate, increasing the unit efficiency thus. The required layout is simple and suitable both for single and multi-compressor units. Tests have been carried out for various working conditions with transcritical and subcritical regimes, different compressor speeds and evaporating pressures in a real unit designed as a booster system.

title: Experimental investigation of evaporators with smooth and inner grooved tubes using CO2 as a refrigerant.

description: Use of CO2 (R744) in refrigeration systems as a natural refrigerant has greatly attracting refrigeration industry. Furthermore, this environmentally friendly refrigerant is being abundant in the atmosphere demonstrates nonflammable, non-explosive and nontoxic behavior. Having a zero ODP (Ozone depletion potential) and GWP (Global warming potential) of one makes CO2 as a great candidate for a future refrigerant. In this study, CO2 is chosen as a refrigerant in a refrigeration system and an air cooled evaporator is considered to determine heat transfer characteristics in the tube side. Two identical evaporators with smooth-grooved copper tubes are used for experiments. The evaporators were in 720 mm x 812 mm dimensions and had 0.12 mm wavy aluminum fins and copper tubes. The tests were conducted in a wind tunnel that was located in a conditioning room. The air-side constant inlet conditions of temperature and humidity are maintained by the conditioning room which consists of an air handling unit; a refrigeration section, an electric heater with 18 kW power, a humidifier and three centrifugal fans to ensure adequate air recirculation in the system. It is noted that nearly 9% increase in inner grooved tube evaporator capacity is observed when compared to non-grooved tube evaporator capacity (11.2 kW).

title: Analysis of several thermal electrical cascades boosted by the absorption working cycle technology.

description: The thermal plants, operated by individual cycles of e.g. Steam Rankine (SR), Organic Rankine (OR) or Gas Turbine (GT) type, are used in practice to produce electrical power. If the thermal cascading method is applied to these cycles, the electrical efficiency can be benefited. The paper analyzes the possibility of creating new power cycles boosted by the absorption working cycle technology. To this extent, a known cycle with a new role, named WORK-CRAFT, is described, in order to form double and treble cascades with the individual power cycles mentioned above, i.e. WORK-CRAFT + SR, WORK-CRAFT + OR and WORK-CRAFT + SR + GT. The paper describes shortly WORK-CRAFT and cascades structure. The cascades are thermally modeled with a simple algorithm, considering that the sink source temperature is variable, 𝑇𝑀,𝑐∈[−30; +40]℃ and WORK-CRAFT is operated by ammonia-water working combination. Also, known reference state of SR, OR and SR + GT operation parameters (e.g. efficiency, temperature) is taken from literature. The model results show that the power efficiency of the mentioned cascades can increase up to 1,35 times, to 2,40 times and to 1,125 times, as compared to SR, OR and SR-GT plants, respectively. Finally, conclusions are formulated.

title: MassIVE MSV000084060 - GNPS - Thapsia Chemical Defense
title: Two-year-old Thapsia garganica plants were purchased from ThapsIbiza S.L. in 2014 and grown in the greenhouses of the Botanical Gardens, Natural History Museum of Denmark, University of Copenhagen, Denmark. At the time of sampling, the plants were four years old. Six plants were dug up and sampled whole at midday, to obtain a representative specialised metabolite profile. At 48 hours prior to sampling, three plants had their leaves clipped (15 on each stem) to mimic herbivory, while the others served as negative controls. Individuals were photographed and labelled and samples from different tissues above and below ground were taken (one full 2mL tube). All samples were snap frozen in liquid nitrogen and kept on dry ice before being stored at -20C.

title: Parkes observations for project P1013 semester 2019APRS_03

description: The paucity of known intermittent pulsars makes individual studies valuable from the perspective of understanding how these pulsars emit and how that emission is changing in time and as a function of frequency. The inherent difficulty in detecting these objects implies that their small population may well simply be a sampling bias, thus studying individual examples in details is fundamentally important in developing a complete understanding of the Galactic population. The Ultra-Wide-Band receiver and the MEDUSA backend provide unprecedented frequency coverage and will allow us to study the emission of the intermittent pulsar J1107-5907 in great detail. In particular, we will focus on the spectral characteristics of the emission, the frequency dependence of emission rates and the time scales on which the emission state switching occurs. By constraining the intermittency time scales we will be able to comment on model predictions, while the spectral index analysis will provide insights into the emission mechanism itself.

description: This data set includes extracted information from 40 CoreTrustSeal (CTS) self-assessment reports, which were publicly available by January 15th 2019 at https://www.coretrustseal.org/why-certification/certified-repositories/. The authors extracted general information from the title pages of the self-assessment reports, as well as responses to criterion "R0 - Background Information / Context".<br>
Sheet "Extracted_Information" includes all extracted info, whereas "Level_of_Curation", "Designated_Community" and "Repository_Type" include normalized and categorized data. The data cleansing / normalization and analysis processes are described in the paper "Eye on Core Trust Seal - Recommendations for Criterion R0 from Digital Preservation and Research Data Management Perspectives" to be released as part of the Proceedings of iPRES2019, the 16th International Conference on Digital Preservation. The data set forms the basis for an extended analysis of Core Trust Seal criterion R0 from the perspectives of the digital preservation and research data management domain.

<strong>Abstract of the accompanying paper:</strong>

The CoreTrustSeal (CTS) is an accepted trustworthy digital repository certification process for both, research data management and digital preservation communities alike. But does it build on concepts known and understood by both of these communities? We take an in-depth look at the CTS requirement <em>R0 - Background Information / Context</em>, in which the applicants are asked to define their repository  type, designated community and level of curation performed. By extracting information from the publicly available assessment reports and cross-checking these against available supporting information, we reflect on CTS from three viewpoints: the process, the institutional, and the community view. We distill concrete recommendations, which will be fed back to the CTS Board as part of the 2019 public call for review.

title: High performance cation exchange membranes synthesized via in-situ emulsion polymerization without organic solvents and corrosive acids

description: Dataset supporting journal publication:

<strong>Abstract:</strong> The synthesis of cation exchange membranes (CEMs) usually involves using organic solvents and/or sulfonation process. In this study, green and scalable synthesis of high performance CEMs is achieved without organic solvents and sulfonation. The synthesis is carried out via in-situ polymerization of lithium styrene sulfonate in porous support. Different preparation procedures are developed and optimized. Functional sulfonate groups were successfully loaded onto and into the membrane support, as verified by FTIR. Besides, water plays an important role during membrane synthesis. By reducing the amount of water used, the ratio of functional polymers to membrane support in the synthesized CEMs is increased. Therefore, the synthesized CEMs show increased ion exchange capacity (IEC). This is significant because it means that high IEC can be achieved without introducing cation exchange resins to the membranes. Finally, the synthesized membranes demonstrate high desalination performance. This new methodology may shed new light on preparing CEMs in an efficient and eco-friendly way.

title: Data for: Functional unification of sex pheromone-receptive glomeruli in the invasive Turkestan cockroach derived from the genus Periplaneta

description: Supplementary movie file legends Supplementary movie 1 The right antennal lobe glomeruli of the male P. americana, showing two macroglomeruli responsive to periplanone-A (A-glomerulus) and periplanone-B (B-glomerulus). Supplementary movie 2 The right antennal lobe glomeruli of the male B. lateralis, showing a single macroglomerulus responsive to periplanone-A and periplanone-B (see text). Note that the glomerulus homologous to the A-glomerulus in P. americana has a size similar to those of ordinary glomeruli. Supplementary movie 3 Mating behavior of P. americana males evoked by the presentation of periplanone. Introducing periplanone-B (5 ng) soaked in filter paper evoked nearly instant mating behavior in males such as wing raising behavior oriented toward the pheromone source. Homsexual behavior with attempts to copulate with neighboring males was also observed. Supplementary movie 4 Behavior of B. lateralis males in response to the presentation of periplanone-B (5 ng) or natural sex pheromone extract (2 female unit). The males showed attraction to the pheromone source and carefully inspected it but never exhibited mating behavior, although the projection neuron that mediates this behavior is exquisitely sensitive to periplanone-B. The presentation of periplanone-A also never evoked mating behavior in the males. Supplementary movie 5 Mating behavior of B. lateralis males in response to the presentation of a female gently anesthetized with CO2. Immediately after careful inspection of the female with antennation, the males exhibited wing raising behavior and attempted to mate with the conspecific female.

title: GSET Somi: A Game-Specific Eye Tracking Dataset for Somi

description: This is an eye tracking dataset of 84 computer game players who played the side-scrolling cloud game Somi. The game was streamed in the form of video from the cloud to the player. The dataset consists of 135 raw videos (YUV) at 720p and 30 fps with eye tracking data for both eyes (left and right). Male and female candidates were asked to play the game in front of a remote eye-tracking device. For each player, we recorded gaze points, video frames of the gameplay, and mouse and keyboard commands. For each video frame, a list of its game objects with their locations and sizes was also recorded. This data, synchronized with eye-tracking data, allows one to calculate the amount of attention that each object or group of objects draw from each player. This dataset can be used for designing and testing game-specific visual attention models.
