Abstract

Objectives
There is limited knowledge about students’ experiences with virtual simulation when using a video conferencing system. Therefore, the aim of this study was to explore how second-year undergraduate nursing students experienced learning through virtual simulations during the COVID-19 pandemic.

Methods
The study had an exploratory design with both quantitative and qualitative approaches. In total, 69 nursing students participated in two sessions of virtual simulation during spring 2020, and 33 students answered online questionnaires at session 1. To further explore students’ experiences, one focus group interview and one individual interview were conducted using a video conferencing system after session 2. In addition, system information on use during both sessions was collected.

Results
Changes in the students’ ratings of their experiences of virtual simulation with the Body Interact™ system were statistically significant. The virtual simulation helped them to bridge gaps in both the teaching and learning processes. Four important aspects of learning were identified: 1) learning by self-training, 2) learning from the software (Body Interact™), 3) learning from peers, and 4) learning from faculty.

Conclusions
We conclude that virtual simulation through a video conferencing system can be useful for student learning and feedback from both peers and faculty is important.

Abstract
MicroRNAs are involved in the pathogenesis of various human malignant tumors. This study aims to explore the role of miR-513b-5p in the malignant proliferation of retinoblastoma (RB) cells and its potential molecular mechanisms. The function-gain and function-loss experiments were performed in Weri-RB1 cells using miR-513b-5 mimics and inhibitors. miR-513b-5p mimics inhibited the proliferation and clone formation and promoted apoptosis of Weri-RB1 cells. In contrast, the miR-513b-5p inhibitor promoted the proliferation and clone formation of Weri-RB1 cells and inhibited cell apoptosis. miR-513b-5p can directly bind to the 3′UTR region of TRIB1 mRNA, and inhibit its protein expression. Overexpression of TRIB1 promoted the proliferation and cloning of Weri-RB1 cells but inhibited their apoptosis. The knockdown of TRIB1 inhibited the proliferation and clone formation of Weri-RB1 cells and promoted cell apoptosis. In addition, miR-513b-5p mimics neutralized the effects of TRIB1 overexpression on the proliferation and apoptosis of Weri-RB1 cells. Finally, miR-513b-5p can inhibit the phosphorylation level of AKT, mTOR, and p70, while TRIB1 played the opposite role. miR-513b-5p inhibits the malignant proliferation of Weri-RB1 cells by repressing the expression of TRIB1. miR-513b-5p and TRIB1 may be the biomarkers and/or key targets for clinical diagnosis and treatment of RB.

Abstract
Artificial intelligence (AI) is a branch of computer science with a variety of subfields and techniques, exploited to serve as a deductive tool that performs tasks originally requiring human cognition. AI tools and its subdomains are being incorporated into healthcare delivery for the improvement of medical data interpretation encompassing clinical management, diagnostics, and prognostic outcomes. In the field of neuroradiology, AI manifested through deep machine learning and connected neural networks (CNNs) has demonstrated incredible accuracy in identifying pathology and aiding in diagnosis and prognostication in several areas of neurology and neurosurgery. In this literature review, we survey the available clinical data highlighting the utilization of AI in the field of neuroradiology across multiple neurological and neurosurgical subspecialties. In addition, we discuss the emerging role of AI in neuroradiology, its strengths and limitations, as well as future needs in strengthening its role in clinical practice. Our review evaluated data across several subspecialties of neurology and neurosurgery including vascular neurology, spinal pathology, traumatic brain injury (TBI), neuro-oncology, multiple sclerosis, Alzheimer’s disease, and epilepsy. AI has established a strong presence within the realm of neuroradiology as a successful and largely supportive technology aiding in the interpretation, diagnosis, and even prognostication of various pathologies. More research is warranted to establish its full scientific validity and determine its maximum potential to aid in optimizing and providing the most accurate imaging interpretation.
Vantourismus – Die neue Freiheit auf vier Rädern eine quantitativ-empirische Analyse von

Van- und Campingtourismus
Authors: Aschauer Wolfgang , Oesterle Carolin 
Published: September 2021

Zusammenfassung
Zusätzlich zum Klassiker der alternativen Reiseformen, dem Backpacking, hat sich im Bereich des Individualtourismus im letzten Jahrzehnt ein neuer Reisetrend, der sogenannte Vantourismus entwickelt. Immer mehr Menschen entscheiden sich dazu, im „Zuhause auf vier Rädern“ für begrenzte Zeit zu verreisen und dabei, anders als klassische Campingtouristen, weitgehend auf klassische Campingplätze und vorbestimmte Reiserouten zu verzichten. Aufgrund des Mangels an empirischer Forschung zu diesem Thema untersucht dieser Beitrag in einer Online-Studie, inwieweit sich VantouristInnen von klassischen CampingtouristInnen unterscheiden. Die Analyse zeigt, dass zahlreiche Diskrepanzen in Hinblick auf Reisemerkmale, Reisemotivationen, Urlaubsbedürfnisse und Lebensstilmerkmale einen eigenständigen Typus des Alternativtourismus nahelegen. Außerdem zeigt die empirische Prüfung eines ganzheitlichen Erklärungsansatzes, dass neben dem Alter, dem Familienstand und der Komfortorientierung vor allem Bedürfnisse der Selbstaktualisierung, Authentizität und Naturverbundenheit ausschlaggebend sind, sich für Vantourismus zu entscheiden.
Geraubte Diamanten, Schmuck und Edelmetalle

Abstract
The essay explores the role of gemstone merchants, jewelers and goldsmiths in the expropriation of diamonds, jewellery and precious stones from the Jewish population of Germany as well as German-occupied countries in the Nazi era. Their participation along with the possibility for them to profit from these efforts will be highlighted, and it will be shown in how far there is proof for the involvement of specific persons. Due to their changeable nature, many of the stolen pieces of jewellery are nigh impossible to trace. For this reason, the essay narrows its focus on individual gemstone merchants, jewellers and goldsmiths to gain insight into their involvement in the robbery. Structures and regulations that were exploited to this end can be observed on an administrative level, in responsible administrative bodies and in the administration of occupied territories. In addition, implementation methods can also be reconstructed, i. e. which middlemen the National Socialists made use of within the circle of gemstone merchants, jewellers and goldsmiths. It shows that all three levels – trade, handicrafts, and sales – benefited from the robbery. On the one hand, jewellers and goldsmiths were used as henchmen for the procurement and evaluation of gemstones, on the other hand, some of these goldsmiths took advantage of the sales orders placed by the National Socialists and obtained the necessary gems and precious stones and metals via the established networks. A scheme in which all participants systematically benefited from the robbery of Jewish property can be identified. Within the framework of foreign currency supply, military raw diamond demand and satisfaction of the Nazi art needs, the participation in the robbery seems limited to an elitist group of gemstone merchants, jewellers and goldsmiths, who were also closely linked to the Nazi elite. In how far the remaining, much larger group of jewellers were actively involved in the robbery of Jewish property remains a question to be answered by further research.
Calibrating Thermomechanical Triaxial Cells for Transient Thermal Loads
Authors: Abdelaziz Sherif L. , Morteza Zeinali Seyed 
Published: September 2021

Abstract
This paper presents a method to integrate the thermal calibration of triaxial cells into the testing procedure, facilitating accurate measurements of thermally-induced pore pressures and volumetric strains during transient thermal loads. For this purpose, a modified thermomechanical triaxial cell that can control the specimen temperature at a specified rate is utilized. Unlike other thermomechanical systems, a separate backpressure pump is connected to each drainage line (top and bottom) measuring the thermally-induced volumetric strains of water filling the respective line. These volumetric strains are measured using a solid acrylic dummy sample under different effective stresses and heating rates. These calibrated system strains were independent of the temperature change rate but impacted by effective stress. These system volumetric strains are withdrawn from the system when applying a transient thermal load to an actual soil specimen either at the drained or undrained boundaries. In the end, we demonstrate the capability of the developed system calibration to capture accurate thermally-induced pore pressures and volumetric strains in two clay specimens subjected to transient heating loads at different rates.
The Physical Reasons to Have Underdamped or Oscillating Variable-Head (Slug) Tests: A Review and a Clarification
Authors: Chapuis Robert P. 
Published: September 2021

Abstract
Variable-head permeability tests are performed in monitoring wells (MWs) or open holes between packers to assess the local value of hydraulic conductivity, K, of gravel, sand, and fractured rock. This article examines physical reasons for having an oscillating water level in the riser pipe, called underdamped (UD) response. The UD solutions are incomplete because they solve one half of the problem—for the water in the pipe—and ignore the second half, seepage in the tested material. This article shows that these half-solutions violate mathematical rules for the second half and thus, are incorrect. Four reasons for oscillations are examined: (1) solid matrix elasticity (storativity), (2) trapped gas, (3) sealing defect, and (4) hydraulic fracturing. Reason (1) yields small oscillations but not large oscillations. Reasons (2–4) can yield large oscillations and explain field data for occurrence, frequency, and damping. Thus, a free space along the casing or some trapped gas is needed to observe large oscillations. Hence, a UD slug test response only proves that the MW (or a packer) is poorly installed. This MW yields wrong values for hydraulic head, gradient, and water analyses. The data of oscillating slug tests are shown to depend upon parameters that are not easy to evaluate. This is why the UD slug tests are found to give poor estimates of K. It is recommended to use suitable drilling techniques to avoid overexcavation, to take 2–4 hours to correctly install a MW, to avoid using compressed gas to start a slug test, and to apply head differences that are high enough to have good results but lower than those producing hydraulic separation. For packer tests, it is recommended to monitor the water pressure between the packers, in the hole below the lower packer and above the upper packer, using three pressure sensors.
Mora-timed, stress-timed, and syllable-timed rhythm classes: Clues in English speech production by bilingual speakers
Authors: Liu Sha , Takeda Kaye 
Published: September 2021

AbstractA growing body of literature suggests that the world's languages can be classified into three rhythm classes: mora-timed languages, stress-timed languages, and syllable-timed languages. However, scholars cannot agree on which rhythmic measures discriminate rhythm classes most satisfactorily and whether the speech rate factor should be considered. In this study, we analyze speech production by bilingual speakers, and compare their production with that of monolingual speakers and ESL speakers. Our rhythmic metric measure results show that when speech rate is taken into consideration, a combination of the two metric measures for vowels,Varco∆Vandvocalic nPVI, is most reliable in discriminating different rhythm classes, while consonants do not seem effective, whether the speech rate factor is included or not.
COORPORATE SOCIAL RESPONSIBILITY DALAM SUDUT PANDANG FIQIH HARTA DAN AKUNTANSI
Authors: Suharti Sri , Setiawan Iwan 
Published: September 2021

Corporate social responsibility in the company law is a company obligation, which aims to increase the role of the private sector in economic development and equitable social welfare. However, until now, this goal has not been achieved, due to the company's reluctance to do so. This is reinforced from the results of previous research, that CSR is not correlated with an increase in company profits, even if donation activities are not related to company operations and profits, then these expenses cannot be recorded as an expense that reduces corporate taxes. This is different from the concept of CSR in the view of wealth fiqh, which places property as the property of Allah and must be used as much as possible for the benefit of all humans. This study aims to compare CSR in the view of wealth and accounting fiqh. This research uses literature review method using data sourced from books, journals / articles, reports and websites. The results of this study found that CSR in the view of wealth fiqh is permissible because there is no fatwa prohibiting it as long as the assets used do not come from business activities that are prohibited in Islam. There is a difference in the concept of assets according to fiqh, namely that assets cannot be stacked for personal gain and must be distributed to others, whereas according to the accounting concept, assets are accumulated and distributed to owners of capital.Key words: capital, cooperate social responsibility, and fiqh of assets.

Maldiciones y profecías: representaciones de la destrucción socionatural de un pueblo en la prensa colombiana
Authors: Espinel Rubio Gladys Adriana 
Published: September 2021

Este artículo indaga por las representaciones que de la destrucción socionatural del casco urbano de Gramalote (Norte de Santander, Colombia) construyeron los diarios La Opinión (local) y El Tiempo (nacional). Es una investigación histórico-hermenéutica, de análisis documental. A partir de la codificación abierta de 48 textos periodísticos de ambos diarios, se construyeron familias categoriales permitiendo determinar cuatro representacionesdel hecho: la persona ama/esclava de la naturaleza; un pueblo sin raíces; ausencia de liderazgo, por último, y causas místicas y proféticas, siendo esta representación la que registró mayores referencias. Así, los medios masivos hacen evidentes los entramados de sentidos que envuelven a las comunidades, permitiendo la comprensión de los desastres y de las historias del fin del mundo en las fronteras de lo socionatural, lo mágico y lo sagrado, desde donde es posible pensar también la gestión del riesgo.
Multiple reflection of plane SH waves by a dipping layer
Authors: Ishii Hiroshi , Ellis Robert M. 
Published: September 2021

abstract
The problem of a plane SH wave incident at the base of a dipping layer has been considered. A solution by multiple reflection for waves incident at any angle perpendicular to strike has been obtained for the amplitude, phase and phase velocity. Numerical values are calculated on the surface. For waves propagating in the up-dip direction the amplitude versus frequency curves for a constant depth to the interface change slowly with increasing dip for dip angles less than 20°. However, for waves propagating in the down-dip direction, the character of the amplitude curves changes rapidly. It is found in these cases that the diffracted wave plays an important role. In addition to satisfying the boundary conditions at the surface and between the media, the diffracted wave must also satisfy additional conditions along a dipping surface lying between the free surface and the boundary between the two media due to the geometrical nature of the reflected wave solution.
It is found that the phase velocities vary rapidly with both period of the wave and depth to the interface, particularly for propagation directions close to an angle which corresponds to vertical incidence in the horizontally layered case.
Deformation of a layered, elastic, half-space by uniformly moving line loads
Authors: Dunkin J. W. , Corbin D. G. 
Published: September 2021

abstract
When a layered half-space is subjected to loads which move uniformly along its surface, the deformation of the half-space depends on the manner in which the load couples into the surface-wave modes. The uniform speed of the load selects those parts of the modal spectra that have phase velocities equal to the load speed. The restriction that the phase velocity be real leads to novel dispersion relations for the leaky modes, but the trapped mode dispersion relations are the usual ones. In this paper general expressions are derived for the solution for uniformly moving line loads on an elastic half-space containing an arbitrary number of layers. In addition to the modal contributions, the solution contains contributions from source singularities and a line integral that reduce to the static solution as the load speed tends to zero. The details are worked out for the special case of a single low-speed layer lying on a high-speed half-space. For the modes, real and imaginary parts of frequency and velocity amplitudes at various depths are presented as functions of frequency. Total velocity waveforms are shown for selected load speeds and depths.
