Optimal Convergence of the Newton Iterative Crank–Nicolson Finite Element Method for the Nonlinear Schrödinger Equation
Authors: Hu Hanzhang , Li Buyang , Zou Jun 
Published: May 2022

Abstract
An error estimate is presented for the Newton iterative Crank–Nicolson finite element method for the nonlinear Schrödinger equation, fully discretized by quadrature, without restriction on the grid ratio between temporal step size and spatial mesh size.
It is shown that the Newton iterative solution converges double exponentially with respect to the number of iterations to the solution of the implicit Crank–Nicolson method uniformly for all time levels, with optimal convergence in both space and time.

Abstract
The design of large-scale nanomaterial production is nowadays a major research topic that requires efficient tools for appropriate decision-making and process simulation is considered among the rational approach to address such difficult issue. The present study deals with process design and economic assessment of Molybdenum Disulfide (MoS2) nanomaterials production at large-scale via solvothermal method basing on our previous bench scale results. The commercial simulator Aspen Plus was used for process modelling and assuming a plant capacity of 100 tonnes/year. The simulation results were used to perform the cost assessment and profitability analysis while taking into account two relevant cases with (Recycle Case) and without recycling of Ethylenediamine and Hydrazine (Base Case). Note that for the technological and economical assessment the effluent treatment system was not taken into account. The total capital investment was estimated to be ca.14.3 M$ for the base case and ca. 17.4 M$ for recycle case, while the total operating costs were about 2945 $ for the base case and 503 $ for the recycle case for the production of 1 kg of MoS2. Thus, in addition to intrinsic advantages associated with the easier preparation and lower environmental impact of solvothermal method, larger production with recycling option can make the process more economically profitable.

Abstract
In order to explore the effects of land use change on the contents of total nitrogen and total phosphorus in deep soil, four land use types (cropland, grassland (7 years), grassland (30 years), and Jujube orchard) were selected from the Yuanzegou watershed in the loess hilly region of northern China. Soil samples at 0–10 m depth were collected to measure the contents of soil total nitrogen (STN) and soil total phosphorus (STP), and their stocks were estimated. The results showed that the STN content showed a decreasing trend with the increase in soil depth, and the lowest STN content of grassland (7 years) was 0.09–0.17 g kg−1. The range of STN content in the watershed was 0.12–0.22 g kg−1 and the coefficient of variation was 10.52–25.90%, which belonged to medium variation. The STP content is stable regionally with the change in soil depth, and does not change much (except for grassland [30 years]). STP content of the watershed is 0.81–1.05 g kg−1 and the coefficient of variation is 9.37–54.69%, which is a high variation. The change trend of STN and STP stocks is consistent with the nitrogen and phosphorus content. The results revealed the dynamic changes in STN and STP after land use change, and estimated the stocks of STN and STP in deep loess, which provided scientific basis for land and soil resource management and sustainable development of the project of returning farmland to forest or grassland in small watershed of loess hilly-gully region.

Authors: Li Yang , Chen Changyong , Qin Guoqing , Jiang Zhouhua 
Published: May 2022

Abstract
We performed a laboratory investigation at 1,873 K using a MoSi2 furnace to study the effect of refractories on inclusions in 55SiCr suspension spring steel. Three types of crucible materials (Al2O3, MgO·Al2O3, and MgO–CaO) were investigated. The results of this study indicated that SiO2, Al2O3, and MgO·Al2O3 were not suitable for making 55SiCr suspension spring steel. By contrast, MgO–CaO was a perfect choice for producing 55SiCr suspension spring steel. The advantages of using MgO–CaO crucibles to smelt 55SiCr spring steel were summarized in three aspects as follows: (i) the stability of MgO–CaO was quite good; (ii) a MgO–CaO crucible could act as a desulfurizer and dephosphorizer; (iii) finally, a MgO–CaO crucible could simultaneously remove Al2O3 inclusions.
Mung bean protein films incorporated with cumin essential oil: development and characterization
Authors: Mojoodi Majid , Nourani Moloud 
Published: May 2022

AbstractBiodegradable films based on mung bean protein (1, 3 and 5%) incorporated with cumin essential oil (EO) (0, 0.25 and 0.5 ml/g protein) were developed. Adding cumin oil and increasing the protein content enhanced the thickness, tensile strength and yellowness. Films incorporated with EO exhibited less water vapor permeability and water solubility, as compared to the control films. A higher antioxidant activity was also obtained by increasing the EO and protein ratios. Films with higher levels of protein displayed lower thermal stability with a lower degradation temperature, as suggested by thermo-gravimetric analyses. In addition, the incorporation of EO reduced thermal stability, as confirmed by the higher weight loss and lower degradation temperature. Furthermore, mung bean protein films containing 0.5 ml cumin oil/g protein had suitable physical characteristics, antioxidant activities, water barrier properties and thermal stability; thus, they can be used as appropriate biodegradable packaging materials for food preservation.
Managing a discourse of reporting: the complex composing of an asylum narrative
Authors: Wadensjö Cecilia , Rehnberg Hanna Sofia , Nikolaidou Zoe 
Published: May 2022

Abstract
The aim of this study is to demonstrate how the presence of an emerging written record may affect the content of an asylum narrative, based on which a decision concerning the asylum claimant’s right to receive protection eventually is taken. The lion’s share of studies on interpreter-mediated asylum interviews to date focus on risks involved with assigning non-professionals to perform the interpreting. This study draws specifically on a 3.5 min-long sequence taken from an asylum interview involving a professional interpreter, working between Russian and Swedish, and the corresponding paragraph of the Swedish-language written minutes, produced in parallel by the caseworker at a Migration Agency office. The study demonstrates something that hasn’t been highlighted much in the literature on asylum interviews, namely the mutual impact of the interpreter-mediated communicative format—the specific turn taking order and the restricted linguistic transparency—and the parallel record keeping; the intricate passage from two spoken languages to an asylum narrative in the form of a text written in one of these languages.
Conditioned pain modulation is not associated with thermal pain illusion
Authors: Oono Yuka , Kubo Hidenori , Takagi Saori , Wang Kelun , Arendt-Nielsen Lars , Kohase Hikaru 
Published: May 2022

Abstract

Objectives
Paradoxical sensations, known as thermal pain illusions, can be evoked by painful cold-heat pulse stimulation. They may provide diagnostic value; however, the possible interaction between conditioned pain modulation and thermal pain illusions has not been explored. The present study examined: (1) whether conditioned pain modulation could be induced by alternating tonic painful cold-heat pulse stimulation; and (2) whether the presence of thermal pain illusions during the conditioning stimulus influences the degree of conditioned pain modulation.

Methods
This study was approved by the Ethics Committee of Meikai University (A1507). Conditioned pain modulation was provoked using alternating painful cold-heat pulses delivered at 20-s intervals applied to the forearm. Thermal pain illusions were qualitatively evaluated, and conditioned pain modulation was assessed quantitatively using the pressure pain threshold as a test stimulus. Differences in the conditioned pain modulation effect between the participants who experienced thermal pain illusions and those who did not were analysed using Student’s t-test.

Results
A significant positive conditioned pain modulation effect (51.0 ± 4.7%, overall effect) was detected. There was no significant difference in conditioned pain modulation between the participants who experienced thermal pain illusions and those who did not (44.3 ± 6.0% and 55.5 ± 6.8%, respectively; p = 0.255).

Conclusions
Conditioned pain modulation induced by alternating painful conditioning cold-heat pulse stimulation was identical during the conditioning stimulation in volunteers with and without thermal pain illusions. Conditioning cold-heat pulse stimulation is useful to evaluate conditioned pain modulation. Moreover, conditioned pain modulation is not influenced by the presence of thermal pain illusions, indicating partially different underlying supraspinal, neuronal networks.

Published: May 2022

Abstract
In modern industrial sewing, the further rise in sewing speed to increase production is mainly influenced by the extent of needle heat generated. The increased needle heat leads to damage to the sewing thread and fabric and a loss in productivity. Hence, the change in sewing needle temperature under various fabric types and sewing conditions is investigated for better understanding. An objective method to assess the generation of needle heat by utilizing a thermal camera is attempted, and the effects of change in needle heat by varying the parameters are assessed. The results from the thermal camera are statistically analyzed. The superimposed seam with a greater number of layers and high needle tension produced high needle heat, whereas poly-poly core spun sewing thread, 100 % polyester fabric, and a high stitch density contribute to the next level of needle heat generation. This investigation considered all the possible influencing parameters objectively and helps in maintaining reduced needle heat for a chosen fabric type and sewing conditions to improve the productivity with increased sewing speed.

Published: May 2022

BACKGROUND AND OBJECTIVE
Bobath therapy, or neurodevelopmental therapy (NDT) is widely practiced despite evidence other interventions are more effective in cerebral palsy (CP). The objective is to determine the efficacy of NDT in children and infants with CP or high risk of CP.

METHODS
Cumulative Index to Nursing and Allied Health Literature, Cochrane Library, Embase, and Medline were searched through March 2021. Randomized controlled trials comparing NDT with any or no intervention were included. Meta-analysis was conducted with standardized mean differences calculated. Quality was assessed by using Cochrane Risk of Bias tool-2 and certainty by using Grading of Recommendations Assessment, Development, and Evaluation.

RESULTS
Of 667 records screened, 34 studies (in 35 publications, 1332 participants) met inclusion. Four meta-analyses were conducted assessing motor function. We found no effect between NDT and control (pooled effect size 0.13 [−0.20 to 0.46]), a moderate effect favoring activity-based approaches (0.76 [0.12 to 1.40]) and body function and structures (0.77 [0.19 to 1.35]) over NDT and no effect between higher- and lower-dose NDT (0.32 [−0.11 to 0.75]). A strong recommendation against the use of NDT at any dose was made. Studies were not all Consolidated Standards of Reporting Trials-compliant. NDT versus activity-based comparator had considerable heterogeneity (I2 = 80%) reflecting varied measures.

CONCLUSIONS
We found that activity-based and body structure and function interventions are more effective than NDT for improving motor function, NDT is no more effective than control, and higher-dose NDT is not more effective than lower-dose. Deimplementation of NDT in CP is required.
A Paradox of Applied Folk Arts. The Contribution of Cooperative Folk Arts to the Construction of the Notion of the Emblematic Creator
Authors: Ament-Kovács Bence 
Published: May 2022

AbstractThe self-definitions of today's folk artists, as well as the concept(s) of folk art of official umbrella and quality assurance organizations, are rooted in complex, interrelated processes. In my study, I focus on the post-World War II concept of folk art, which is full of contradictions, but, despite all protests, has had an undeniable impact on the folk art of today. The system of applied folk arts paradoxically fostered the prominence of individual creators, in contrast to the communication of its novel cooperatives in the decades after World War II, which emphasized communal work. These creators – often possessing truly authentic folk art knowledge (some having gained their reputation before World War II) but no longer following the peasant way of life – were depicted by the media in rural or bucolic genre situations, thereby heavily aestheticizing the concepts of folk and folk art. At the same time, socialist cultural policy also emphasized their status as artists and creators, making them key figures in the cooperatives' work for decades as lead designers, prompting them to revitalize their local motif stock. At this point, another paradox of the Applied Folk Arts Council's perspective emerges, as the representation of the folk art of emblematic regions can increasingly be seen as the representation of the style of an individual (lead designer or charismatic artist). In my opinion, considering the 19th-century roots of the process, the definition of today's folk artists' products as unique works of art and the profound respect for design skills is rooted in this perspective that focuses on the work of iconic personalities, as I also point out in my case study analyzing Tiszafüred pottery through the work of several generations, a style that was adapted by Sándor Kántor and became known as Karcag pottery.
Nanostructured Ti–13Nb–13Zr for dental implant applications produced by severe plastic deformation
Authors: Klinge Lina , Siemers Carsten , Kluy Lukas , Groche Peter 
Published: May 2022

AbstractNanostructured titanium plays an important role in biomedical applications, especially in dentistry, as the nanostructured surface promotes bone cell growth and simultaneously prevents bacterial colonization. Nanostructured microstructures can be obtained through Severe Plastic Deformation processes. In this paper, thermomechanical processing via Equal Channel Angular Swaging for the continuous production of nanocrystalline Ti–13Nb–13Zr (TNZ) is investigated with respect to applications in dental implantology. TNZ is a second-generation β-rich (α + β) medical alloy which can consist of the three phases α- and β-phase as well as αʺ-martensite. The αʺ-martensite has a very low Young’s modulus and a comparably low strength with high ductility allowing metal forming even at low temperatures. By adjusting different phase volume fractions, a wide range of mechanical properties can be realized, especially Young’s modulus between 50 and 90 GPa at a yield strength exceeding 950 MPa making it an ideal material for dental implants and abutments.

Mnemic Images in the Early Works of Sigmund Freud
Authors: Błocian Ilona 
Published: May 2022

Freud was interested in the problem of memory from the time of his very early works. The processes taking place in memory, imaging, remembering and forgetting images focused his attention and were one of the pillars of shaping his conception of the unconscious and mind as “the storehouse of total memory,” which in one of his works he compared to “the Eternal City of Rome” (Culture and Its Discontents), which accumulate images-memories gathered throughout life. Shifts, changes, deformations, strong emotional components determine the specificity of many processes of remembering and forgetting, a specific “coding” of information in the form of visual, acoustic and other images. Nowadays, there are indications of Freud’s views in various dimensions of scientific research on memory and the consciousness of the importance of these approaches in our culture and its discovery of the role of autobiographical memory.
