Published: July 2018

The research is mainly to investigate the surface roughness by the mechanical polishing for the processing of alumina ceramic materials. In the experiment, the ceramic test piece was placed between the ceramic work ring and the grinding disc and then grinded firstly with an alumina grinding slurry with a particle size of 10 μm to make the original roughness of the test piece reach Ra value of 1.49 μm. Then the silicon carbide slurry polishing was employed to conduct the experiments by changing the concentration of the polishing, particle size, load, rotation and time to observe the polishing effect of ceramic materials under different parameters. The results showed that the silicon carbide particle size of 2μm, with the polishing time of 50 min, the disc speed of 90 rpm, the concentration of 35%, the original surface roughness of alumina ceramic Ra 1.49μm could be downed to 0.22 μm. The improvement rate could reach 94%. And the greater the specimen load with the better grinding efficiency, the smaller the load caused worse cutting force between alumina and the specimen surface. However, the better the surface roughness when the time kept going. Furthermore, alumina ceramic test piece after precision mechanical polishing by 3D surface roughness profiler and scanning electron microscope (SEM) analysis, the observation found that the wave of the original test piece rugged, after grinding and polishing wave front and grinding scratches had been removed, and a smooth surface was obtained.

Semiconductor quantum dots (QDs) have attracted tremendous attentions for their unique characteristics for solid-state lighting and thin-film display applications. A simple chemical method was used to synthesis quantum dots (QDs) of zinc sulfide (ZnS) with low cost. The XRD) shows cubic phase of the prepared ZnS with an average particles size of (3-29) nm. In UV-Vis. spectra observed a large blue shift over 38 nm. The band gaps energy (Eg) was 3.8 eV and 3.37eV from the absorption and photoluminescence (PL) respectively which larger than the Eg for bulk. QDs-LED hybrid devices were fabricated using ITO/ PEDOT: PSS/ Poly-TPD/ ZnS-QDs/ with different electron transport layers and cathode of LiF/Al layers. The EL spectrum reveals a broad emission band covering the range 350 - 700 nm. Current-voltage (I–V) characteristics indicate that the output current is good according to the few voltages (8, 10, 11 and 12 V) used which gives acceptable results to light generation. Using TPBi and Alq3 as electron transport layer gives good enhancement to light generation in compares with that of QDs only. The emissions causing the luminescence were identified depending on the chromaticity coordinates (CIE 1931).
Recent Advances in the Discovery and Delivery of TLR7/8 Agonists as Vaccine Adjuvants
Authors: Dowling David J
Published: July 2018

The need for new adjuvants is absolutely cardinal to the development of new vaccines and to further optimizing current immunization approaches. However, only a few classes of adjuvants are presently incorporated in vaccines approved for human use. Recent advances in the discovery and delivery of TLR agonists as vaccine adjuvants have begun to open up a new toolbox for vaccinologists. At the forefront of this movement is the use of synthetic small molecule TLR7/8 agonist–based adjuvants. In this review, we emphasize the importance of vaccine formulation science in driving recent developments in TLR7/8 adjuvanticity, summarize some of the most current and notable studies in this field, and discuss desirable attributes of next generation TLR7/8 adjuvants for use in enhancing vaccine responses in vulnerable populations, such as the very young. Finally, we explore advances that may further edge the development of TLR7/8 adjuvant–based vaccine formulations toward clinical human evaluation.

Recent guidelines on cardiovascular disease prevention suggest multimodal behavioral interventions for psychosocial risk factors and referral for psychotherapy in the case of clinically significant symptoms of depression and anxiety overall. Accordingly, psychologists of the Italian Association for Cardiovascular Prevention, Rehabilitation and Epidemiology (GICR-IACPR) have reviewed the key components of psychological activities in cardiovascular prevention and rehabilitation (CPR). The aim of this study was to elaborate a position paper on the best practice in routine psychological activities in CPR based on efficacy, effectiveness and sustainability. The steps followed were: i) a review of the latest international guidelines and position papers; ii) analysis of the evidence-based literature; iii) a qualitative analysis of the psychological services operating in some reference Italian cardiac rehabilitation facilities; iv) classification of the psychological activities in CPR as low or high intensity based on the NICE Guidelines on psychological interventions on anxiety and depression. We confirm the existence of an association between depression, anxiety, social factors, stress, personality and illness onset/outcome and coronary heart disease. Evidence for an association between depression, social factors and disease outcome emerges particularly for chronic heart failure. Some positive psychological variables (e.g., optimism) are associated to illness outcome. Evidence is reported on the impact of psychological activities on â€˜newâ€™ conditions which are now indicated for cardiac rehabilitation: pulmonary hypertension, grown-up congenital heart, end-stage heart failure, implantable cardioverter-defribrillator and mechanical ventricular assist devices, frail and oldest-old patients, and end-of-life care. We also report evidence related to caregivers. The Panel divided evidence-based psychological interventions into: i) low intensity (counseling, psycho-education, self-care, self-management, telemedicine, self-help); or ii) high intensity (individual, couples and/or family and group psychotherapy, such as stress management). The results show that psychotherapy is mainly consisting of cognitive-behavior therapy, interpersonal therapy, and short-term psycho-dynamic therapy. The current data further refine the working tools available for psychological activities in CPR, giving clear directions about the choice of interventions, which should be evidence-based and have at least a minimum standard. This document provides a comprehensive update on new knowledge and new paths for psychologists working in the CPR settings.

Published: July 2018

The definition of common international guidelines for the compilation of high quality hydrogeological maps has been attempted from the second half of the last century for hydrogeologists, to solve the lack of uniformity among national guidelines due to the various geological-hydrogeological and climatic situations of different countries worldwide. With this aim, the China Geological Survey and the Geological Survey of Italy-ISPRA are undertaking cooperative research in implementing 1:50,000 scale hydrogeological survey and mapping at selected sites in both countries. The project intends to develop a new generation of hydrogeological and groundwater resource maps with descriptive effectiveness and consistency with field survey data. The project will promote improvements of technologies in hydrogeological survey and mapping of the two countries and might even be agreed at a wider international level. Chinese and Italian hydrogeological guidelines have similar aspects as well as concerns: 1) the undertaking of field surveys at the 1:50,000 scale and more detailed (1:25000) scale; 2) building of a hydrogeological database; 3) publication of the official map in both paper and electronic form; 4) inclusion of several small scale maps inlayed at the margin of a main map in the hydrogeological map layout; 5) comparable level in required survey quota. Furthermore, more attention will be paid to a 3D map, conceptual model, aquifer structure, groundwater cycle and hydrogeological parameter description.In contrast, the most important difference regards the following. The hydrogeological mapping guidelines of Italy have integrated specifications for both survey and mapping, i.e. they deal with a structural layout characterized by survey contents followed by mapping contents and reflect a technical route of surveying for mapping. In contrast, there are no mapping contents in the current hydrogeological guidelines of China and these then needed to be formulated. The Italian guidelines could provide important references for China in legend organization, mapping rules, survey quota and so on.Finally, the collaboration between China and Italy is of great significance for the two ancient civilized countries sharing the “One Belt and One Road” international initiative.
Evaluations of the downward velocity of soil water movement in the unsaturated zone in a groundwater recharge area using δ18 O tracer: the Kumamoto region, southern Japan
Authors: Okomura Azusa , Hosono Takahiro , Boateng Dennis , Shimada Jun
Published: July 2018

Water and substances from the surface infiltrate the unsaturated zone before reaching groundwater. Yet, little study has been done on the unsaturated zone due to the difficulty of sampling. A lot of studies have been carried out on the top soil down to a depth of one metre and on shallow aquifers because they are easily accessible for sampling. The unsaturated zone of the Kumamotoregion recharge areas is important due to concerns about groundwater pollution from agriculture. The aim of this study was to estimate the downward velocity of soil water movement through the unsaturated zone and the recharge rate using δ18O as a tracer. Five sampling sites were selected and a core was taken from each site. The cores were cut into 0.1 m pieces and soil water was extracted from each to analyze for δD and the δ18O content. Average δD and δ18O compositions of soil water were similar to the isotopic compositions of summer precipitation. Annual average recharge rate and the downward velocity of soil water in each site were estimated by fitting a vertical δ18O profile pattern to a precipitation δ18O time series as a theoretical water displacement flow model for recharge. An estimated annual average recharge rate in the recharge area ranged from 745 to 1058 mm/yr with the annual average downward velocity of 1.37 to 2.34 m/yr. Based on the estimated downward velocity, the infiltration time for soilwater to reach the aquifer was determined as ranging from 9 to 24 years, which corresponds with previous groundwater age estimations presented in an earlier published study on the same area. It was assumed that contaminants will reach aquifers in 9 to 25 years if the effects of diffusion and microbiological reaction are not taken into account.
Study of Aqueous and Non-Aqueous Phase Liquid in Fractured Double-Porosity Soil Using Digital Image Processing
Authors: Kok Fong Loke , Rahman Narthan Abd , Nazir Ramli , Lewis Roland W.
Published: July 2018

The leakage and spillage of non-aqueous phase liquids (NAPLs) and aqueous phase liquids (APLs) contribute to groundwater contamination, resulting in groundwater pollution and rendering the quality of groundwater unsafe for drinking and agriculture. Ensuring the availability and sustainable management of water and sanitation for all was the goal and target of the 2030 United Nations agenda for sustainable development, consisting of a plan of action for the population, the planet and general prosperity. This paper is intended to investigate the aqueous and non-aqueous phase liquid migrations in a deformable double-porosity soil, which has become important for both sustainable groundwater use and the comprehensive understanding of the behaviour of liquid migration into groundwater. A modelling experiment was conducted in an attempt to study the pattern and behaviour of aqueous and non-aqueous phase liquid migration in fractured double-porosity soil using a digital image processing technique. The results of the experiments show that the flow of the APL and NAPL migration was not uniformly downward. Faster migration occurred where the soil surface was cracked compared to other locations where the soil surface was not cracked, even when liquids such as toluene were not used. It was concluded that the factors that significantly influenced the APL and NAPL migration were the structure of the soil sample, fracture pattern of the soil sample, physical interaction i.e. bonding between the liquid and soil sample, and the capillary pressure of the fluid. This study indicates that digital image analysis can provide detailed information to help researchers better understand and be able to simulate the pattern and characteristics of liquid migration that have an influence on groundwater resources.

An inverse semigroup approach to the C*-algebras and crossed products of cancellative semigroups
Authors: Aukhadiev Marat
Published: July 2018

We give a newdefinition of the semigroup C*-algebra of a left cancellative semigroup, which resolves problems of the construction by X. Li.Namely, the newconstruction is functorial, and the independence of ideals in the semigroup does not influence the independence of the generators. It has a group C*-algebra as a natural quotient. The C*-algebra of the old construction is a quotient of the newone. All this applies both to the full and reduced C*-algebras. The construction is based on the universal inverse semigroup generated by a left cancellative semigroup. We apply this approach to connect amenability of a semigroup to nuclearity of its C*-algebra. Large classes of actions of these semigroups are in one-to-one correspondence, and the crossed products are isomorphic. A crossed product of a left Ore semigroup is isomorphic to the partial crossed product of the generated group.
Revised Self-Report Assessment of Functional Visual Performance (R–SRAFVP)—Part I: Content Validation
Authors: Zemina Cheryl L. , Warren Mary , Yuen Hon K.
Published: July 2018

OBJECTIVE. We describe the development and content validation of the revised Self-Report Assessment of Functional Visual Performance (R–SRAFVP).

METHOD. The content validation process consisted of three stages: (1) three occupational therapy experts in low vision rehabilitation revised items on the 38-item SRAFVP via written feedback and semistructured interview, (2) eight occupational therapy low vision experts evaluated items for relevance and provided feedback on the rating scale, and (3) five adults with low vision provided feedback on item clarity via cognitive interviewing.

RESULTS. In Stage 1 review, 21 items were added, totaling 59 items. In Stage 2 evaluation, 9 items were eliminated, resulting in the 50-item R–SRAFVP with a 4-point scale. The scale content validity index of the R–SRAFVP was .9. Stage 3 cognitive interviewing provided no substantive changes in content.

CONCLUSION. R–SRAFVP content was relevant to evaluate the ability of adults with low vision to complete vision-dependent daily tasks and was understandable by these participants.
A statistical examination of the effects of stratospheric sulfate geoengineering on tropical storm genesis
Authors: Wang Qin , Moore John C. , Ji Duoying
Published: July 2018

Abstract. The thermodynamics of the ocean and atmosphere partly determine variability in tropical cyclone (TC) number and intensity and are readily accessible from climate model output, but an accurate description of TC variability requires much higher spatial and temporal resolution than the models used in the GeoMIP (Geoengineering Model Intercomparison Project) experiments provide. The genesis potential index (GPI) and ventilation index (VI) are combinations of dynamic and thermodynamic variables that provide proxies for TC activity under different climate states. Here we use five CMIP5 models that have run the RCP4.5 experiment and the GeoMIP stratospheric aerosol injection (SAI) G4 experiment to calculate the two TC indices over the 2020 to 2069 period across the six ocean basins that generate TCs. GPI is consistently and significantly lower under G4 than RCP4.5 in five out of six ocean basins, but it increases under G4 in the South Pacific. The models project potential intensity and relative humidity to be the dominant variables affecting GPI. Changes in vertical wind shear are significant, but it is correlated with relative humidity, though with different relations across both models and ocean basins. We find that tropopause temperature is not a useful addition to sea surface temperature (SST) in projecting TC genesis, perhaps because the earth system models (ESMs) vary in their simulation of the various upper-tropospheric changes induced by the aerosol injection.

Abstract. Particulate nitrate contributes a large fraction of secondary aerosols. Despite understanding of its important role in regional air quality and global climate, long-term continuous measurements are rather limited in China. In this study, we conducted online measurement of PM2.5 nitrate for two years from March 2014 to February 2016 using the Monitor for Aerosols and Gases in ambient Air (MARGA) in the western Yangtze River Delta (YRD), eastern China, and investigate the main factors that influenced its temporal variations and formation pathways. Compared to other sites in China, an overall high concentration of particulate nitrate was observed with a mean value of 15.8 µg m−3 (0.5 to 92.6 µg m−3). Nitrate on average accounted for 32 % of the total mass of water-soluble ions and the proportion increased with PM loading, indicating that nitrate is a major driver of haze pollution episodes in this region. Sufficient ammonia drove most nitrate into the particle phase in the form of ammonium nitrate. A typical seasonal cycle of nitrate was observed with the concentrations in winter on average two times higher than those in summer mainly due to different meteorological conditions. In summer, the diurnal variation of particulate nitrate was determined by the thermodynamic equilibrium, resulting in a much lower concentration during daytime despite of a considerable photochemical production. Air masses from polluted YRD and biomass burning region contributed to the high nitrate concentration during summer. In winter, particulate nitrate didn’t reveal an evident diurnal variation. Regional transport from northern China played an important role in enhancing nitrate concentration. Eighteen nitrate episodes were selected to understand the processes that drive the formation of high concentration of nitrate. Rapid nitrate formation was observed during the pre-episode (the day before nitrate episode day) nights, and dominated the increase of total water-soluble ions. Calculated nitrate from N2O5 hydrolysis was highly correlated to and accounted for 80 percent of the observed nitrate, suggesting that N2O5 hydrolysis was a major contributor to the nitrate episodes. Our results suggested that rapid formation of nitrate could be a main cause for extreme aerosol pollution events in YRD during winter, and illustrated the urgent needs to control the NOx emission.

Abstract. A highly miniaturized limb
sounder for the observation of the O2 A-band to derive temperatures
in the mesosphere and lower thermosphere is presented. The instrument
consists of a monolithic spatial heterodyne spectrometer (SHS), which is able
to resolve the rotational structure of the R-branch of that band. The
relative intensities of the emission lines follow a Boltzmann distribution
and the ratio of the lines can be used to derive the kinetic temperature. The
SHS operates at a Littrow wavelength of 761.8 nm and heterodynes a
wavelength regime between 761.9 and 765.3 nm with a resolving power of about
8000 considering apodization effects. The size of the SHS is
38 × 38 × 27 mm3 and its acceptance angle is
±5∘. It has an etendue of 0.01 cm2 sr. Complemented by front
optics with an acceptance angle of ±0.65∘ and detector optics,
the entire optical system fits into a volume of about 1.5 L. This allows us
to fly this instrument on a 3- or 6-unit CubeSat. The vertical field of view
of the instrument is about 60 km at the Earth's limb when operated in a
typical low Earth orbit. Integration times to obtain an entire altitude
profile of nighttime temperatures are on the order of 1 min for a vertical
resolution of 1.5 km and a random noise level of about 1.5 K. Daytime
integration times are 1 order of magnitude shorter. This work presents the
design parameters of the optics and a radiometric assessment of the
instrument. Furthermore, it gives an overview of the required
characterization and calibration steps. This includes the characterization of
image distortions in the different parts of the optics, visibility, and phase
determination as well as flat fielding.
Empirical high-resolution wind field and gust model in mountainous
and hilly terrain based on the dense WegenerNet station networks
Authors: Schlager Christoph , Kirchengast Gottfried , Fuchsberger Juergen
Published: July 2018

Abstract. A weather diagnostic application for automatic generation of gridded wind fields in near-real time, recently developed by the authors (Schlager et al., 2017), is applied to the WegenerNet Johnsbachtal (JBT) meteorological station network. This station network contains eleven meteorological stations at elevations from about 600 m to 2200 m in a mountainous region in the north of Styria, Austria. The application generates, based on meteorological observations with a temporal resolution of 10 minutes from the WegenerNet JBT, mean wind and wind gust fields at 10 m and 50 m height levels with a high spatial resolution of 100 × 100 m and a temporal resolution of 30 minutes. These wind field products are automatically stored to the WegenerNet data archives, which also include long-term averaged weather and climate datasets from post-processing. A main purpose of these empirically modeled products is the evaluation of convection-permitting dynamical climate models as well as investigating weather and climate variability on a local scale. The application's performance is evaluated against the observations from meteorological stations for representative weather conditions, for a month including mainly thermally induced wind events (July 2014) and a month with frequently occurring strong wind events (December 2013). The overall statistical agreement, estimated for the vector-mean wind speed, shows a reasonably good modeling performance with somewhat better values for the strong wind conditions. The difference between modeled and observed wind directions depends on the station location, where locations along mountain slopes are particularly challenging. Furthermore, the seasonal statistical agreement was investigated from five-year climate data of the WegenerNet JBT in comparison to nine-year climate data from the high-density WegenerNet meteorological station network Feldbach Region (FBR) analyzed by Schlager et al., (2017)In general, the five-year statistical evaluation for the JBT indicates similar performance as the shorter-term evaluations of the two representative months. Because of the denser WegenerNet FBR network, the statistical results show better performance for this station network. The application can now serve as a valuable tool for intercomparison with and evaluation of wind fields from high-resolution dynamical climate models in both the WegenerNet FBR and JBT regions.
Response of hydrology and CO2 flux to experimentally altered rainfall frequency in a temperate poor fen, southern Ontario, Canada
Authors: Radu Danielle D. , Duval Tim P.
Published: July 2018

Abstract. Predicted changes to the precipitation regime in many parts of the world
include intensifying the distribution into lower frequency, large magnitude
events. The corresponding alterations to the soil moisture regime may affect
plant growth and soil respiration, particularly in peatlands, where large
stores of organic carbon are due to gross ecosystem productivity (GEP)
exceeding ecosystem respiration (ER). This study uses lab monoliths
corroborated with field measurements to examine the effect of changing
rainfall frequency on peatland moisture controls on CO2 uptake in an
undisturbed cool temperate poor fen. Lab monoliths and field plots containing
mosses, sedges, or shrubs received either 2.3, 1, or 0.5 precipitation
events per week, with total rainfall held constant. Decreasing rain frequency led to lower
near-surface volumetric moisture content (VMC), water table (WT), and soil
tension for all vegetation types, with minimal effect on evapotranspiration.
The presence of sedges in particular led to soil tensions of ≥100 cm of
water for a sizeable duration (37 %) of the experiment. Altered rainfall
frequencies affected GEP but had little effect on ER; overall, low-frequency
rain led to a reduced net CO2 uptake for all three vegetation types.
VMC had a strong control on GEP and net ecosystem exchange (NEE) of the
Sphagnum capillifolium monoliths, and decreasing rainfall frequency
influenced these relationships. Overall, communities dominated by mosses
became net sources of CO2 after 3 days without rain, whereas
sedge communities remained net sinks for up to 14 days without rain. The results
of this study demonstrate the hydrological controls of peatland CO2
exchange dynamics influenced by changing precipitation frequency; furthermore, they suggest
these predicted changes in frequency will lead to increased sedge GEP but
limit the carbon-sink function of peatlands.
The importance of small artificial water bodies as sources of
methane emissions in Queensland, Australia
Authors: Grinham Alistair , Albert Simon , Deering Nathaniel , Dunbabin Matthew , Bastviken David , Sherman Bradford , Lovelock Catherine E. , Evans Christopher D.
Published: July 2018

Abstract. Emissions from flooded land represent a direct source of anthropogenic greenhouse gas emissions. Methane emissions from large, artificial water bodies have previously been considered, with numerous studies assessing emission rates and relatively simple procedures available to determine their surface area and generate upscaled emissions estimates. In contrast, the role of small artificial water bodies (ponds) is very poorly quantified, and estimation of emissions is constrained both by a lack of data on their spatial extent, and a scarcity of direct flux measurements. In this study, we quantified the total surface area of water bodies
Stochastic reconstruction of spatio-temporal rainfall pattern by
inverse hydrologic modelling
Authors: Grundmann Jens , Hörning Sebastian , Bárdossy András
Published: July 2018

Abstract. Knowledge about the spatio-temporal rainfall pattern is required as input for distributed hydrologic models to perform several tasks in hydrology like flood runoff estimation and modelling. Normally, these pattern are generated from point observations on the ground using spatial interpolation methods. However, such methods fail in reproducing the true spatio-temporal rainfall pattern especially in data scarce regions with poorly gauged catchments or for highly dynamic, small scaled rainstorms which are not well recorded by existing monitoring networks. Consequently, uncertainties are associated with poorly identified spatio-temporal rainfall pattern in distributed rainfall-runoff modelling since the amount of rainfall received by a catchment as well as the dynamics of the runoff generation of flood waves are underestimated. For addressing this problem we propose an inverse hydrologic modelling approach for stochastic reconstruction of spatio-temporal rainfall pattern. The methodology combines the stochastic random field simulator Random Mixing and a distributed rainfall-runoff model in a Monte-Carlo framework. The simulated spatio-temporal rainfall pattern are conditioned on point rainfall data from ground monitoring networks as well as the observed hydrograph at catchment outlet and aims to explain measured data at best. Since we conclude from an integral catchment response on a three-dimensional input variable, several candidates of spatio-temporal rainfall pattern are possible which also describe their uncertainty. The methodology is testet on a synthetic rainfall-runoff event on subdaily timesteps and spatial resolution of 1 km2 for a catchment covered by rainfall partly. Results show that a set of plausible spatio-temporal rainfall pattern can be obtained by applying the inverse approach. Furthermore, results of a real world study for a flash flood event in a mountainious arid region are presented. They underline that knowledge about the spatio-temporal rainfall pattern is crucial for flash flood modelling even in small catchments and arid and semiarid environments.
Robust active wake control in consideration of wind direction variability and uncertainty

Published: July 2018

Abstract. The prospects of active wake deflection control to mitigate wake-induced power losses in wind farms have been demonstrated by large eddy simulations, wind tunnel experiments and recent field tests. However, it has not yet been fully understood how the yaw control of wind farms should take into account the variability of current environmental conditions in the field and the uncertainty of their measurements. This research investigated the influence of dynamic wind direction changes on active wake deflection by intended yaw misalignment. For this purpose the wake model FLORIS was used together with wind direction measurements recorded at an onshore met mast in flat terrain. The analysis showed that active wake deflection has a high sensitivity towards short-term wind directional changes. This can lead to an increased yaw activity of the turbines. Fluctuations and uncertainties can cause the attempt to increase the power output to fail. Therefore a methodology to optimise the yaw control algorithm for active wake deflection was introduced, which considers dynamic wind direction changes and inaccuracies in the determination of the wind direction. The evaluation based on real wind direction time series confirmed that the robust control algorithm can be tailored to specific meteorological and wind farm conditions and that it can indeed achieve an overall power increase in realistic inflow conditions. Furthermore recommendations for the implementation are given which could combine the robust behaviour with reduced yaw activity.

Defining data librarianship: a survey of competencies, skills, and training
Authors: Federer Lisa
Published: July 2018

Objectives: Many librarians are taking on new roles in research data services. However, the emerging field of data librarianship, including specific roles and competencies, has not been clearly established. This study aims to better define data librarianship by exploring the skills and knowledge that data librarians utilize and the training that they need to succeed.Methods: Librarians who do data-related work were surveyed about their work and educational backgrounds and asked to rate the relevance of a set of data-related skills and knowledge to their work.Results: Respondents considered a broad range of skills and knowledge important to their work, especially “soft skills” and personal characteristics, like communication skills and the ability to develop relationships with researchers. Traditional library skills like cataloging and collection development were considered less important. A cluster analysis of the responses revealed two types of data librarians: data generalists, who tend to provide data services across a variety of fields, and subject specialists, who tend to provide more specialized services to a distinct discipline.Discussion: The findings of this study suggest that data librarians provide a broad range of services to their users and, therefore, need a variety of skills and expertise. Libraries hiring a data librarian may wish to consider whether their communities will be best served by a data generalist or a subject specialist and write their job postings accordingly. These findings also have implications for library schools, which could consider adjusting their curricula to better prepare their students for data librarian roles. This article has been approved for the Medical Library Association’s Independent Reading Program.

Numerical simulation of dynamics of sediments disposed in the marine coastal zone of the south-eastern Baltic
Authors: Sokolov Andrei , Chubarenko Boris
Published: July 2018

Three dumping sites located at the south-eastern part of the Baltic Sea at shallow depths near the shore of the Sambian Peninsula are considered. The first and second ones are located south and north of the Vistula Lagoon inlet, and are used now for disposing dredged material extracted from the Kaliningrad Seaway Canal. The third dumping site is located near the northern shore of the Sambian Peninsula, east of Cape Gvardeyskiy and assigned for disposing the dredged material extracted from the fairway to the Pionerskiy Port located nearby. All three dumping sites are located either in front of or not far from the eroded segments of the shore. The question behind the study is: Is it possible that disposed material is naturally transported from the damping site to the shore and accumulates there to protect it from erosion? A numerical hydrodynamic transport 3D model (MIKE) was used to model sediment transport under different wind actions. The winds with the speed stronger than 15 m/s wash out disposed material completely from the dumping site and spread it over a wide area with a negligible layer thickness. Winds of about 7–10 m/s transport material along the shore at a distance of a few kilometres; that may be useful for shore protection. Winds with a speed of about 5 m/sec or less do not lead to resuspension of sediments. The first location of the dumping site looks very ineffective for potential protection of the shore nearby. On the other hand, the second and especially the third locations are favourable for the transport of disposed material to the shore; the most favourable conditions are at onshore or alongshore currents.
The Internet of Bawdies: Transmedial drag and the onlining of trans-feminist and queer performance archives, a workshop essay
Authors: Cowan T. L.
Published: July 2018

Like the practices of drag itself, this workshop essay has been produced in and with community, geared towards many audiences and reliant on the expertise and creative intelligence of these communities and audiences. The Internet of Bawdies is the Internet of too much body. My working description of the Internet of Bawdies is, the (forced) digitization and onlining (publication, connectivity, searchability) of previously non-digital/not-onlined (Cowan & Rault 2018) ephemera of trans- feminist and queer (TFQ) community-based expressive cultures, including but not limited to drag, burlesque, kink shows, porn and erotica across medium, spoken word, slam and other text-based performance forms, and cabaret, whether is explicitly sexual or not, as well as the internet of sex work and other modes of consentual, adult online embodiment that exceed, transgress, resist or transform heteronormative, monogamous, reproductive bodies. While there are many sexes, genders and orientations in the Internet of Bawdies, here I focus on the ethics of TFQ digitization in this context. “Transmedial drag” is what I have identified as a method of study, knowledge production and citational practice developed on/in/of/with the Internet of Bawdies in mind. Transmedial drag are the processes involved in moving across media/mediums (for example: from live performance, to video documentation, to digital archive to online platform), which creates a sort of pastiche of the ‘original,’ denaturalizing its status as ‘originary’ and teaching us something new about the excesses and limitations of each media form. In particular, transmedial drag is a method for ethical engagements that researchers working with TFQ in the online environment, especially re-mediating materials to an online environment, might find they are already doing. There is a story in the moving across media, and transmedial drag is set of practices to tell those stories.
Locating Femme Theory Online
Authors: Schwartz Andi
Published: July 2018

Paying close attention to the Internet has revelatory potential for femme theory. Femme, a queerly feminine sexual and gender identity, has so far been under theorized and is often treated as unimportant or even suspect in queer and feminist studies (Martin, 1996; Harris and Crocker, 1997; Maltry and Tucker, 2002; Dahl, 2017). Work on femme has proliferated in response to this (mis)treatment of femme (Volcano and Dahl, 2008; Rose and Camilleri, 2002; Harris and Crocker, 1997; Duggan and McHugh, 1996; Nestle, 1992b), and looking to the Internet reveals a rich tradition of femme theorizing. In this paper I argue that femme theory is often produced through cultural and community forms and emphasize the potential of blogs and social media as sites of this knowledge production. Femme theory found online challenges the masculinist standards of queerness and, I argue, the masculinist standard of inquiry. I rely on a range of feminist, cultural, and queer theorists who engage with theories of epistemology to shift our understanding of the concept “theory” itself in order to make space for femme epistemology. In addition to challenging the superiority of masculinity, hegemonic femininity and patriarchal gender roles, and defying stereotypes about femmes, femme theory also complicates several aspects of formal knowledge production. Looking to the Internet is a crucial way to locate femme knowledge and attend to gaps in feminist and queer theory.
Functional neuromarkers for neuropsychology
Authors: Kropotov Juri D.
Published: July 2018

This article is written to commemorate the 40th year of the scientific career of Professor Maria Pąchalska, Head of the Department of Neuropsychology and Neurorehabilitation at Krakow University, President of the Polish Neuropsychological Society, and the Editor-in-chief of Acta Neuropsychologica, with whom I have been collaborating for over ten years. The subject matter of our work includes the introduction of HBI methodology to clinics and the search for neuromarkers in particular disease entities.

What is the new methodology we are talking about? In general, we think of a biomarker (or biological marker) as a characteristic that can be objectively measured and evaluated as an index of normal or pathological biological processes. For disorders of the central nervous system, biomarkers can be classified as clinical, neuroimaging, biochemical or genetic, according to the type of information they provide. Expectations for the development of biomarkers are high, since they could lead to a significant improvement in diagnosing and possibly preventing neurological and psychiatric diseases.

Neuroimaging is an array of neuroscience methods that include the techniques of magnetic resonance imaging (MRI), functional MRI (fMRI), and PET (positron emission tomography), as well as Electroencephalogram (EEG) and Magnetoencephalogram (MEG) techniques, such as quantitative EEG (QEEG), event related de/synchronization (ERD/ERS) and event-related potentials (ERPs).
Usage of Customer Profitability Management Tools on the Textile Market of Bosnia and Herzegovina
Authors: Lalic Srdjan , Stevic Stevan , Tesic Dejan
Published: July 2018

The modern market puts new demands on companies in terms of customer segmentation and relations with them. Companies facing the pressure of globalisation must adopt new views in the domain of adaptation of all functions in the company, which have a trend of integration, including the function of marketing and that of accounting. One of the results of the integration of company functions is, among others, the concept of customer profitability management. The subject of this paper is analysis of the profitability management tools of domestic companies operating on the textile market of Bosnia and Herzegovina. The aim of the paper is to point out the necessity of applying customer profitability management tools as one of the ways that companies adapt better to changes that occur on the textile market of Bosnia and Herzegovina. The methods used in this paper are analysis, synthesis, and generalisation in the part related to the literature review. Statistical methods are used for analysis of data collected on the basis of research conducted on a simple random sample of domestic companies operating on the textile market of Bosnia and Herzegovina.
Methods of Evaluating Knitted Fabrics
with Elastomeric Threads in the Design
Process of Compression Products
Authors: Kowalski Krzysztof , Kłonowska Magdalena , Ilska Anita , Sujka Witold , Tyczyńska Magdalena
Published: July 2018

One of the most important stages in the design process of compression products is describing
the relationship between the force and elongation of the knitted fabric, using appropriate
and scientifically justified force values in the fabric undergoing a stretching and relaxation
test, in the form of a hysteresis loop. Research on this issue was carried out on two variants
of knitted fabrics with elastomeric threads – a warp and a weft – knitted one. Based on
the functions of the relation between the force and relative elongation determined and on
Laplace’s law, compression bands with intended values of unit pressure were designed and
manufactured and then subjected to experimental verification. In addition, a procedure was
presented for dividing compression fabrics into specific compression classes.

Petrositis as a complication of otitis media with effusion – a case report
Authors: Bartoszewicz Robert , Niemczyk Elżbieta , Karchier Emilia , Niemczyk Kazimierz , Sokołowski Jacek
Published: July 2018

Authors presented a case of a 15-year-old girl diagnosed with otitis media with effusion complicated by petrositis. Otitis media with effusion is not a common cause of petrositis. The condition occurs mostly in adults, rarely in a pediatric population. Patients with suspected petrositis require magnetic resonance and computed tomography imaging. Conservative treatment is not sufficient when symptoms appear. Surgical treatment is essential in order to complete removal of inflamed tissues. A few surgical approaches are recommended (e.g. middle fossa approach).
