Women survivors’ accounts of seeing psychologists: harm or benefit?
Authors: Marsden Sally , Humphreys Cathy , Hegarty Kelsey
Published: December 2020

Many women who experience intimate partner violence are left with significant and long-lasting mental health effects resulting in survivors seeking help from psychologists. However, the voices of women who have sought such help are mostly absent in research. To address this gap, we interviewed 20 women survivors of intimate partner violence about their experiences when seeing psychologists. We analysed this data thematically and developed two main themes relating to women’s experiences of psychologists after intimate partner violence. These themes were: mirroring abuse or being supportive and it did me quite a bit of damage. Our research suggests that these women experienced suboptimal mental healthcare after intimate partner violence and that the effects of this were not neutral but were damaging. Positive experiences suggested that these women appreciated practices aligned with feminist and trauma and violence-informed approaches. This study fills in some details about women’s experiences, which can be used to further inform trauma and violence-informed approaches.
Dynamic interference of the high harmonics from photoisomerizing 1,3-cyclohexadiene
Authors: Kaneshima Keisuke , Ninota Yuki , Sekikawa Taro
Published: December 2020

The ionization potential difference between photoexcited and ground-state molecules results in a phase difference between their high harmonics, which causes high harmonic interference. The interference enables us to reveal how ionization potential of the photoexcited molecules evolves along the electronic relaxation path from the Franck–Condon state to the electronic ground state. We observe the ultrafast electron dynamics of a photoisomerizing molecule, 1,3-cyclohexadiene, via high harmonic interference. The experimental observations reveal that the electronic relaxation of 1,3-cyclohexadiene takes 200 fs, and the photoisomerization to 1, 3, 5-hexatriene takes an additional 450 fs.

Published: December 2020

The first metastable assembly intermediate of the eukaryotic ribosomal small subunit (SSU) is the SSU Processome, a large complex of RNA and protein factors that is thought to represent an early checkpoint in the assembly pathway. Transition of the SSU Processome towards continued maturation requires the removal of the U3 snoRNA and biogenesis factors as well as ribosomal RNA processing. While the factors that drive these events are largely known, how they do so is not. The methyltransferase Bud23 has a role during this transition, but its function, beyond the nonessential methylation of ribosomal RNA, is not characterized. Here, we have carried out a comprehensive genetic screen to understand Bud23 function. We identified 67 unique extragenicbud23Δ-suppressing mutations that mapped to genes encoding the SSU Processome factorsDHR1,IMP4,UTP2(NOP14),BMS1and the SSU proteinRPS28A. These factors form a physical interaction network that links the binding site of Bud23 to the U3 snoRNA and many of the amino acid substitutions weaken protein-protein and protein-RNA interactions. Importantly, this network links Bud23 to the essential GTPase Bms1, which acts late in the disassembly pathway, and the RNA helicase Dhr1, which catalyzes U3 snoRNA removal. Moreover, particles isolated from cells lacking Bud23 accumulated late SSU Processome factors and ribosomal RNA processing defects. We propose a model in which Bud23 dissociates factors surrounding its binding site to promote SSU Processome progression.
Genetic structure of coast redwood (Sequoia sempervirens [D. Don] Endl.) populations in and outside of the natural distribution range based on nuclear and chloroplast microsatellite markers
Authors: Breidenbach Natalie , Gailing Oliver , Krutovsky Konstantin V.
Published: December 2020

Coast redwood (Sequoia sempervirens) naturally growing in southern Oregon and northern California is one of the few conifer tree species that are polyploid. Despite its unique ecological and economic importance, its population genetic structure is still insufficiently studied. To obtain additional data on its population genetic structure we genotyped 317 samples collected from populations in California (data set C) and 144 trees growing in a provenance trial in France (data set F) using 12 nuclear (five random nuclear genomic nSSRs and seven expressed sequence tag EST-SSRs) and six chloroplast (cpSSRs) microsatellite or simple sequence repeat (SSR) markers, respectively. These data sets were also used as reference to infer the origin of 147 coast redwood trees growing in Germany (data set G). Coast redwood was introduced to Europe, including Germany as an ornamental species, decades ago. Due to its fast growth and high timber quality, it could be considered as a potential commercial timber species, especially in perspective to climate warming that makes more regions in Germany suitable for its growing. The well performing trees in colder Germany could be potential frost resistant genotypes, but their genetic properties and origin are mostly unknown. Within the natural range in southern Oregon and northern California, only two relatively weak clusters were identified, one northern and one southern, separated by the San Francisco Bay. High genetic diversity, but low differentiation was found based on the 12 nuclear SSR markers for all three data sets F, C and G. We found that investigated 147 German trees represented only 37 different genotypes. They showed genetic diversity at the level less than diversity observed within the natural range in the northern or southern cluster, but more similar to the diversity observed in the southern cluster. It was difficult to assign German trees to the original single native populations using the six cpSSR markers, but rather to either the northern or southern cluster. The high number of haplotypes found in the data sets based on six cpSSR markers and low genetic differentiation based on 12 nuclear SSRs found in this study helps us study and better understand population genetic structure of this complex polyploid tree and supports the selection of potential genotypes for German forestry.

Published: December 2020

This study explores speed choice behavior of travelers under realistic and fabricated Dynamic Message Signs (DMS) content. Using web-based survey information of 4,302 participants collected by Amazon Mechanical Turk in the United States, we develop a set of multivariate latent-based ordered probit models participants. Results show female, African-Americans, drivers with a disability, elderly, and drivers who trust DMS are likely to comply with the fabricated messages. Drivers who comply with traffic regulations, have a good driving record, and live in rural areas, as well as female drivers are likely to slow down under fabricated messages. We highlight that calling or texting, taking picture, and tuning the radio are distracting activities leading drivers to slow down or stop under fictitious scenarios.

Introduction

Serum creatinine (SCr) testing has been the mainstay of kidney function assessment for decades despite known limitations. Cystatin C (CysC) is an alternative biomarker that is generally less affected than SCr by pertinent non-renal factors in hospitalized patients, such as muscle mass. Despite its potential advantages, the adoption of CysC for inpatient care is not widespread. At one hospital with CysC testing, we demonstrated a significant rise in non-protocolized use over the last decade. This study uses qualitative methods to provide the first report of how clinicians understand, approach, and apply CysC testing in inpatient care.

Methods

Fifteen clinicians from various disciplines were interviewed about their experience with inpatient CysC testing. The semi-structured interviews were audio-recorded, transcribed verbatim, and analyzed thematically using a phenomenological approach.

Results

Knowledge and confidence with CysC varied greatly. Clinicians reported first learning about the test from colleagues on consulting services or multidisciplinary teams. The majority believed CysC to provide a more accurate measure of kidney function than SCr. Common scenarios for CysC ordering included medication dosing, evaluation of acute kidney injury, and a thorough evaluation of kidney function in patients with risk factors for an altered SCr. Facilitators for ordering CysC included the availability of rapid results turnaround and the automated calculation of glomerular filtration rate based on the biomarker. Barriers to use included a lack of education about CysC, and the absence of an institutional protocol for use.

Discussion

Clinicians at our site decided independent of institutional guidance whether and when CysC added value to patient care. While the majority of study participants indicated advantages to rapid turnaround CysC testing, its use depended not just on the features of the specific case but on clinician familiarity and personal preference. Findings from this research can guide the implementation and expansion of CysC testing.
RNAi-based screens uncover a potential new role for the orphan neuropeptide receptor Moody in Drosophila female germline stem cell maintenance
Authors: Ma Tianlu , Matsuoka Shinya , Drummond-Barbosa Daniela
Published: December 2020

Reproduction is highly sensitive to changes in physiology and the external environment. Neuropeptides are evolutionarily conserved signaling molecules that regulate multiple physiological processes. However, the potential reproductive roles of many neuropeptide signaling pathways remain underexplored. Here, we describe the results of RNAi-based screens inDrosophila melanogasterto identify neuropeptides/neuropeptide receptors with potential roles in oogenesis. The screen read-outs were either the number of eggs laid per female per day over time or fluorescence microscopy analysis of dissected ovaries. We found that the orphan neuropeptide receptor encoded bymoody(homologous to mammalian melatonin receptors) is likely required in somatic cells for normal egg production and proper germline stem cell maintenance. However, the egg laying screens had low signal-to-noise ratio and did not lead to the identification of additional candidates. Thus, although egg count assays might be useful for large-scale screens to identify oogenesis regulators that result in dramatic changes in oogenesis, more labor-intensive microscopy-based screen are better applicable for identifying new physiological regulators of oogenesis with more subtle phenotypes.
Integrating economic measures of adaptation effectiveness into climate change interventions: A case study of irrigation development in Mwea, Kenya
Authors: Narita Daiju , Sato Ichiro , Ogawada Daikichi , Matsumura Akiko
Published: December 2020

As climate change adaptation is becoming a recognized policy issue, the need is growing for quantitative economic evaluation of adaptation-related public investment, particularly in the context of climate finance. Funds are meant to be allocated not to any types of beneficial investments with or without climate change but to projects regarded as effective for climate change adaptation based on some metrics. But attempts at such project-specific evaluation of adaptation effects are few, in part because such assessments require an integration of various types of simulation analyses. Against this background, we conduct a case study of a Kenyan irrigation development project using a combination of downscaled climate data, runoff simulations, yield forecasting, and local socioeconomic projections to examine the effects of interventions specifically attributable to climate change adaptation, i.e., how much irrigation development can reduce the negative effects of climate change in the future. The results show that despite the uncertainties in precipitation trends, increased temperatures due to climate change have a general tendency to reduce rice yields, and that irrigation development will mitigate income impacts from the yield loss–for example, for the median scenario, the household income loss of 6% in 2050 due to climate change without irrigation development is flipped to become positive with the project. This means that the irrigation development project will likely be effective as a means for climate change adaptation.

Published: December 2020

Pathogen identification is a critical step during diagnosis of infectious diseases. Matrix-Assisted Laser Desorption/Ionization Time-Of-Flight mass spectrometry (MALDI-TOF-MS) has become the gold standard for identification of microorganisms cultured on solid media in microbiology laboratories. Direct identification of microbes from liquid specimen, circumventing the need for the additional overnight cultivation step, has been successfully established for blood culture, urine and liquor. Here, we evaluate the ability of MALDI-TOF MS for direct identification of pathogens in synovial fluid after liquid enrichment in BacT/Alert blood culture bottles. Influence of synovial specimen quality on direct species identification with the MALDI BioTyper/Sepsityper was tested with samples inoculated from pretested native synovia with concomitant inoculation of blood or pus, or highly viscous fluid. Here, we achieved >90% concordance with culture on solid medium, and only mixed-species samples posed significant problems. Performance in routine diagnostics was tested prospectively on bottles inoculated by treating physicians on ward. There, we achieved >70% concordance with culture on solid media. The major contributors to test failure were the absence of a measurable mass signal and mixed-specimen samples. The Sepsityper workflow worked well on samples derived from BacT/Alert blood culture bottles inoculated with synovial fluid, giving concordant results to identification from solid media. Host remnant material in the inoculum, such as blood or pus, had no detrimental effect on identification score values of the BioTyper system after processing with the Sepsityper workflow, and neither had the initial viscosity of the synovial sample.

Introduction

Influenza morbidity and mortality are significant in the countries of South America, yet influenza vaccination is as low as 56.7% among pregnant women, reaching 76.7% of adults with chronic diseases. This article measures the relative values for the vaccination hesitancy indicators of confidence, complacency and convenience by risk-groups in urban areas of five countries of South America with contrasting vaccination rates, analyzing their association with sociodemographic variables and self-reported immunization status.

Methods

An exit survey was applied to 640 individuals per country in Brazil, Chile, Paraguay, Peru and Uruguay, distributed equally across risk groups of older adults, adults with risk factors, children ≤6 and pregnant women. Indicators were constructed for vaccine confidence, complacency and convenience. Analysis of variance and multiple logistic analysis was undertaken.

Results

Adults with risk factors are somewhat more confident of the influenza vaccine yet also more complacent. Convenience is higher for mothers of minors. Children and older adults report higher levels of vaccination. The 3Cs are more different across countries than across risk groups, with values for Chile higher for confidence and those for Uruguay the lowest. Complacency is lower in Brazil and higher in Uruguay. Results suggest that confidence and complacency affect vaccination rates across risk groups and countries.

Conclusions

Influenza vaccine confidence, complacency and convenience have to be bolstered to improve effective coverage across all risk groups in the urban areas of the countries studied. The role played by country contextual and national vaccination programs has to be further researched in relation to effective coverage of influenza vaccine.

Authors: Gnutov Maxim S. , Sizonenko Alexander B.
Published: December 2020

The influence of software protection on various information systems is analyzed. Using set theory, the use of computational resources for the joint solution of direct tasks and information protection tasks in an automated system is described. A hybrid implementation of computing in a CPU + GPU system is proposed. The relevance of using the branch and bound method to compile a minimum schedule of information security tasks in a hybrid multiprocessor system is considered. The features of processing data structures by various types of calculators are indicated. The computational strategies of the branch and bound method with the greatest possibility of acceleration with limited resources are analyzed. The efficiency criterion is selected, the performance indicators are considered when applying the frontal and one-sided branching strategies depending on the complexity of the calculations and the amount of occupied memory. The generalized indicator of efficiency is defined. The prospects of applying the considered method in distributed systems through distributed programming are emphasized.
Cognitive aggregate-flow metamodel of the process automatic spacecraft flight control
Authors: Kovtun Vladimir S.
Published: December 2020

Currently, there is an urgent scientific problem of ensuring the effective implementation of the automatic spacecraft (AS) flight program, taking into account the material, energy and information resource limitations of onboard systems (OS). The consumption of OS resources largely depends on the synergistic phenomena that occur during intersystem interaction in the AS. By using these phenomena, it is possible to increase the efficiency of the use of existing resources, as well as to supplement them with new "synergistic" resources [1,2]. At the same time, synergistic phenomena can lead to premature development of the OS resource and unforeseen (non-calculated) failures and accidents [3]. For purposeful search and use of these synergistic phenomena, it is necessary to conduct a special study of the processes occurring on board. Research becomes possible only when moving from the system-cybernetic model of AS as a " black box "to a system-cybernetic model that provides" transparency "of AS as a" white box", which requires high accuracy and complexity of analysis of processes occurring on board [4]. This situation determines the urgency of developing new engineering techniques and modeling technologies. To create them, it is necessary to solve the problem of the initial stage of building models that describe in one form or another the engineering knowledge of OS development experts and flight control specialists [5]. The development of a universal method for solving the problem of the initial stage of modeling is significantly complicated due to the wide variety of OS, each of which has its own emergent and synergistic properties, which largely depend on the "non-clonability" of their elements [6,7].

In order to simplify the modeling of real OS functioning processes, taking into account their specifics, it is proposed to carry out preliminary development of a formalized cognitively structured aggregate-flow metamodel ("model of models") of the AS flight control process, which contains information about potentially existing capabilities for controlling the state of vehicles in various conditions of implementation of nominal and abnormal processes. Creating a conceptual metamodel allows you to make the transition from the subject formalized model to the next stages of modeling-formal-mathematical and material-functional modeling, which take into account the individual characteristics of the processes on board the AS when controlling its flight. At the same time, the problems of overcoming the complexity of the metamodel, including its dimension, are solved.
Neural network method of adaptive control system of imitation of physical forces
Authors: Obukhov Artem D. , Siukhin Alexandr A.
Published: December 2020

This research examines the subject area of ​​physical forces simulation systems, implemented on the basis of controlled running platforms. The time spent by the control system to receive and process information about the state of the user and the system causes a software and hardware delay that prevents the system from responding in a timely manner to the user's natural movement. The control system delay problem cannot be solved using direct data of the states of the man-machine system. The aim of the presented research is to develop a new control method that allows analyzing the state of the user and the platform, forecasting his movements and organizing the process of managing the system for simulating physical forces. The method is implemented using neural networks. The scientific novelty of the method includes in the use of neural networks to solve the problems of forecasting user actions and automating decision-making to control the system for simulating physical forces. Each presented neural network is formed to perform separate tasks. The first is to create a forecast of changes in the states of a man-machine system. The second is to determine whether the forecasted state belongs to any state in the historical data. The third determines the required change in the states of the parameters of the man-machine system to achieve the forecasted state. The possibilities of using the described approach are presented on the example of a treadmill that adapts to the real parameters of the user's locomotion. The results obtained confirm a significant reduction in the complexity of the implementation of the control process after applying the neural network method. The area of application of the neural network control method is adaptive information systems and automatic control systems, in which it is necessary to minimize the system delay time and response to user locomotion.
Cloud Storage Protection Scheme Based on Fully Homomorphic Encryption
Authors: Mohammed Mohammed A. , Abed Fadhil S.
Published: December 2020

Cloud computing allows enterprises and individuals to have a less physical infrastructure of software and hardware. Nevertheless, there are some concerns regarding privacy protection which may turn out to be a strong barrier. Traditional encryption schemes have been used to encrypt the data before sending them to the cloud. However, the private key has to be provided to the server before any calculations on the data. To solve this security problem, this paper proposes a fully homomorphic encryption scheme for securing cloud data at rest. The scheme is based on prime modular operation, its security depends on factoring multiple large prime numbers (p1, p2,...pn) up to n, which is formed from very large prime numbers up to hundreds of digits as this is an open problem in mathematics. In addition, the elements of the secret key are derived from a series of mathematical operations and the calculation of an Euler coefficient within the modular of integers. Furthermore, it adds the complexity of noise to the plaintext using the number of users of the Cloud Service Provider. Moreover, its randomness is evaluated by the National Institute of Standards and Technology statistical tests, and the results demonstrating that the best statistical performance was obtained with this algorithm.
Influence of Natural Fibers on the Performance of Hot Mix Asphalt for the Wearing Course of Pavement
Authors: Mahmood Omar T. , Ahmed Sheelan A.
Published: December 2020

Cracking in the flexible pavement is a serious problem that reduces the service life of the roads pavement unless they are treated with great care. Since flexible pavement is very weaker in tension than in compression, it is usually necessary to consider the tensile stresses and some type of additives to improve asphaltpavement performance, and one of the most effective ways of improving asphalt pavement performance is to reinforce asphalt mixtures by incorporating natural fibers. The main objective of this study is to use palm fiber, which is locally available, in hot mix asphalt mixtures. To achieve this objective, the Marshall test and indirect tensile strength test were conducted on four asphalt mixtures with different types of natural fibers (Coconut, Corn, Palm, and Sisal), added in varying percentages 0.1, 0.2, 0.3, 0.4, and 0.5% and different lengths of fiber 0.5, 1, 1.5, and 2 cm. Based on the analyzed results, it can be concluded that the use of palm fiber increased the Marshall stability by 20% as compared with the conventional mixture and raised up the retained tensile strength ratio up to 92%. Finally, the use of 0.2% content of natural fiber at 1.5 cm length gave a better performance for the mixtures.
Memory Load Alters Perception-Related Neural Oscillations during Multisensory Integration
Authors: Michail Georgios , Senkowski Daniel , Niedeggen Michael , Keil Julian
Published: December 2020

Integrating information across different senses is a central feature of human perception. Previous research suggests that multisensory integration is shaped by a context-dependent and largely adaptive interplay between stimulus-driven bottom-up and top-down endogenous influences. One critical question concerns the extent to which this interplay is sensitive to the amount of available cognitive resources. In the present study, we investigated the influence of limited cognitive resources on audiovisual integration by measuring high-density electroencephalography (EEG) in healthy participants performing the sound-induced flash illusion (SIFI) and a verbaln-back task (0-back, low load and 2-back, high load) in a dual-task design. In the SIFI, the integration of a flash with two rapid beeps can induce the illusory perception of two flashes. We found that high compared with low load increased illusion susceptibility and modulated neural oscillations underlying illusion-related crossmodal interactions. Illusion perception under high load was associated with reduced early β power (18–26 Hz, ∼70 ms) in auditory and motor areas, presumably reflecting an early mismatch signal and subsequent top-down influences including increased frontal θ power (7–9 Hz, ∼120 ms) in mid-anterior cingulate cortex (ACC) and a later β power suppression (13–22 Hz, ∼350 ms) in prefrontal and auditory cortex. Our study demonstrates that integrative crossmodal interactions underlying the SIFI are sensitive to the amount of available cognitive resources and that multisensory integration engages top-down θ and β oscillations when cognitive resources are scarce.

SIGNIFICANCE STATEMENTThe integration of information across multiple senses, a remarkable ability of our perceptual system, is influenced by multiple context-related factors, the role of which is highly debated. It is, for instance, poorly understood how available cognitive resources influence crossmodal interactions during multisensory integration. We addressed this question using the sound-induced flash illusion (SIFI), a phenomenon in which the integration of two rapid beeps together with a flash induces the illusion of a second flash. Replicating our previous work, we demonstrate that depletion of cognitive resources through a working memory (WM) task increases the perception of the illusion. With respect to the underlying neural processes, we show that when available resources are limited, multisensory integration engages top-down θ and β oscillations.
The Geopolitics of the Yemen War during the Corona Pandemic
Authors: Kadri Jude
Published: December 2020

This article addresses the geopolitics of Bab-al-Mandeb in the war on Yemen, which began in 2015 and continues to this day, in the context of a global pandemic. It makes the hypothesis that securing Bab-al-Mandeb is fundamental for US imperialism. For reasons to do with its global hegemony, the United States cannot permit another force, specifically the Houthis of Yemen, to exercise control over Bab-al-Mandeb. Although many reasons could account for the senseless war, the security of Bab-al-Mandeb—a strategic chokepoint of trade and oil flows—over-determinedly (as in an Althusserian concept) explains the war’s continuity.

In spite of the fact that the linchpin of the United Arab Emirates’ (UAE) politicostrategic objectives rests on keeping close connections to a small number of countries in the West and the Middle East, the Emiratis have in recent years strived to forge a somewhat multifaceted relationship with Asia. This is aiming primarily to secure the UAE’s own increasingly growing economic and financial interests in a resurgent East. The UAE seeks to make the most of its current regional standing and advantageous position by serving as a bridgehead of sorts to boost the sprouting presence of the rising Asian powers in the Middle East. The Asians are equally capitalizing on the Emirati looking East in order to vouchsafe their sedimented interests in the region and beyond.
“Boundlessly Different”
Authors: Steinbrecher Bernhard , Achhorner Bernhard
Published: December 2020

Brass music has become increasingly popular in recent years in Europe’s German-speaking regions, especially among young people, who attend brass festivals, such as Woodstock der Blasmusik, in great numbers.

This article examines this phenomenon within the context of its historical weight. Particularly in Austria, brass music is intertwined strongly with local cultural activity and heritage, alpine folklore, and national identity, with the Habsburg Monarchy and the Nazi era as well as with the rise of Volkstümliche Music and Austrian popular music. The study pinpoints the initial spark of the current popularity to the early 1990s, when young brass musicians set new tones musically and culturally. It illustrates how bands such as Mnozil Brass and Innsbrucker Böhmische, and later Viera Blech and LaBrassBanda, renegotiated established conceptions, ideas, and attitudes, and how they have, or have not, overcome habitualized ways of performing and enjoying brass music.

On a broader level, the article uncovers how narratives related to regionality, Heimat, community, institutionalization, virtuosity, internationality, openness, corporality, and hedonistic pleasure all come together, at times in contradictory ways, in the media and musicians’ ethical-aesthetic discussion about contemporary brass music. Ultimately, a close music-analytical reading of selected songs shows how the music fosters and reflects these interrelations.

This article uses textual and discourse analysis to examine how Annie Clark, who records and performs under the alias St. Vincent, problematized the electric guitar’s gendered address by designing a Signature Collection for Music Man, a subsidiary of equipment manufacturer Ernie Ball. It first contextualizes the industrial efforts to make the electric guitar more accessible to girls during Clark’s adolescence and their limitations. It then analyzes Clark’s promotional strategies for the collection. Most branding opportunities available to female music industry professionals interested in extending their commercial shelf life often affirm conventionally feminine modes of creative self-expression, such as fashion and cosmetics. Clark’s guitar challenges such gender essentialism by highlighting her own virtuosity as a queer musician, songwriter, and producer while giving players a different set of tools with which to create new sounds.

In a short review the effective methods of optimization of structure and properties of high-performance polymers obtained from thermoreactive nitrogen-containing resins such as benzoxazines, bismaleimides, cyanate esters have been analysed. High crosslinked density copolymer thermosets are synthesized through chemical interactions between reactive functional groups, which belong to the monomers/oligomers used. The different possible processes such as copolymerization or formation of interpenetrating polymer networks are discussed. The high-performance polymers and composites from thermoreactive nitrogen-containing resins are effectively used in aerospace industry and microelectronics as materials possessing high thermal and thermooxidative stability, radiation and chemical resistance, low water absorption, low dielectric loss, high dimension stability and high adhesion to different substrate. The performance characteristics of this kind of materials can be controlled by changing their composition, temperature-time curing schedule, using catalytic systems.

Methodology of using megavolt electrons for investigation of the functionality of thin polymer films of polycyanurates (PCN) is described. The relevance of research is determined by the prospects of using films as a functional basis for improvement of track-etched technologies of nanoporous nuclear filters, where ionizing radiation is used in most of technological stages of their production. Functionality control is the main criterion for the qualification of films on the suitability for production of nuclear filters on their base. Development of megavolt electrons radiation methods is promising for monitoring the functionality of filters. Radiation technologies are universal and able to provide maximum information content on investigations of the characteristics of materials to qualify them for suitability of practical use. To control the functionality of the films, the methodology for research and testing of thin polymer films using powerful electron beams of 1-2 MeV has been developed. The features of these methods and the results of their application at the control of functionality and for the qualification of the films based on crosslinked polycyanurates, synthesized by in situ polycyclotrimerization of dicyanate ester of bisphenol E in the presence of dimethylphthalate (DMPh) of the composition PCN/DMPh=70/30 wt.%, on the suitability for production of nanoporous track membranes are discussed. Key words: electron beams, nuclear membranes, thermostable polycyanurates, radiation stability, functional testing.

New cross–linked and linear polyurethane compositions with different content of various reactive metal[Ni,Zn,Cu]inorganic modifiers (MIM) were synthesized. The results of IR spectroscopy confirm the reaction and structural reorganization in the system under the influence of MIM. Thus, in the region of stretching vibrations of NH groups of the urethane fragment, a shoulder increase was noted in the region of weakly bound stretching vibrations of NH groups at 3456 cm-1 and a new band at 4314 cm-1 appears, which indicates the presence of hydrogen bonds with the chlorine ion CuCl2. The presence of MIM in polyurethane leads to a shift of valence vibration of urethane group band νС =O to the region of 1723 cm-1 and the appearance of an intensive shoulder 1711 cm-1, which indicates the formation of a coordination bond C = O → Cu[Cl2]. The appearance in the IR spectrum of the polymer with MENM content of three new bands with maximums (530, 558 and 637) cm–1 indicates the formation of a coordination bond N → Cu. It was shown that the presence of transition metals dichlorides in the polymer structure provides opportunities for target production of polyurethane compositions with a set of specified properties, namely: fungicide properties, which were provided by the presence of Zn- and Cu-chlorides, photostability which was provided by the presence of Ni-chloride. In this case, the incorporation of active compounds into the structure of the polymer excludes the diffusion of MIM on the surface of the material with subsequent removal and thus prolongs the protective functions of the coating – resistance to biocorrosion, UV radiation, chemical agents, heat resistance while maintaining high adhesion / cohesion. Keywords: polyurethane compositions, cross-linked, linear, inorganic modifiers, coatings, adhesion, stabilyty, environment.
Anthropological Analysis of the Celtic Cemetery Unearthed By Road No. 83 at Ménfőcsanak
Authors: Köhler Kitti
Published: December 2020

The results of a general anthropological and paleopathological examination of 24 individuals from the earliest Celtic cemetery in the Carpathian Basin, excavated at Ménfőcsanak are presented in this paper. Due to the low number of the buried individuals, the demographic analysis could not be done. According to the metric and morphological investigation of the skulls, the serie is characterized by the long, dolichocrane-headed individuals, despite the assumption that the earliest Celtic immigrants were mainly short, brachycrane-headed. Due to the pathological analysis, the populaton buried here had the usual diseases with the exception of lesions on the skull of a female that indicate the possibility of surgical trepanation.
Terra Sigillata-Funde in Der Einheimischen Siedlung Lágymányos

Samian ware of Lágymányos. 65 pieces of Samian ware were unearthed during the excavation of the Eraviscus settlement of Lágymányos. It is a fairly small amount compared to the number of PGW finds, which is well over a thousand pieces. Despite all this, imported ceramic finds unearthed in these sites allow us to set up a timeframe of the lifespan of the settlement. A third of the finds originate from Italia, accordingly, it is presumable that in the middle to the second half of the first century this settlement was already a part of the Roman commercial circuit. Three potteries of Italian origin classifiable into three groups includes a relatively great amount of good quality A2 ware.

The 26 pieces include early-type Drag. 29 and early forms also appear amongst the undecorated vessels. There are fewer Central Gaulish finds and even less (3 pieces) of Rheinzabern products. According to the Samian wares found the life of the settlement can be traced up until the Marcomannic wars (166–180 AD).

Later finds suggest that the settlement was abandoned or sparsely populated afterward.
Addressing taxonomic challenges for Internet Use Disorders in light of changing technologies and diagnostic classifications. •

Drawing a distinction between mobile and non-mobile Internet Use Disorders is an important step to clarify blurred current concepts in the field of behavioral addictions. Similarly, future technological advances related to virtual or augmented reality, artificial intelligence or the Internet of things might lead to further modifications or new taxonomies. Moreover, diagnostic specifiers like offline/online might change with technological advances and trends of use. An important taxonomical approach might be to look for common structural characteristics of games and applications that will be amenable to new technical developments. Diagnostic and taxonomical approaches based on empirical evidence are important goals in the study of behavioral addictions.
A body without a head
Authors: Chavoshian Ali , Park Sophia
Published: December 2020

Along with the recent development of various theories of the body, Lacan’s body theory aligns with postmodern thinkers such as Michael Foucault and Maurice Merlot-Ponti, who consider body social not biological. Lacan emphasizes the body of the Real, the passive condition of the body in terms of formation, identity, and understanding. Then, this condition of body shapes further in the condition of bodies of women and laborers under patriarchy and capitalism, respectively. Lacan’s ‘not all’ position, which comes from the logical square, allows women to question patriarchy’s system and alternatives of sexual identities. Lacan’s approach to feminine sexuality can be applied to women’s spirituality, emphasizing multiple narratives of body and sexual identities, including gender roles. In the social discernment and analysis in the liberation theology, we can employ the capitalist discourse, which provides a tool to understand how people are manipulated by late capitalist society, not knowing it. Lacan’s theory of ‘a body without a head’ reflects the current condition of the human body, which manifests lack, yet including some possibilities for transforming society.
