Published: June 2023

BackgroundThe treatment approach of vestibular schwannoma (VS) has seen a change in recent years, with a trend away from radical surgery towards preservation of cranial nerve function. A recent study reported recurrences as long as 20 years after complete removal of VS.ObjectiveTo report the risk of recurrence and progression in our patient population the authors retrospectively reviewed outcomes of patients.MethodsCases with unilateral VS who had undergone primary microsurgery via retrosigmoidal approach between 1995 and 2021 were investigated. Complete tumor removal was defined as gross total resection (GTR), a capsular remnant was categorized as near total resection (NTR) and residual tumor was designated as subtotal resection (STR). The primary endpoint was radiological recurrence-free survival.Results386 patients fulfilled the inclusion criteria of the study and were evaluated. GTR was achieved in 284 patients (73.6%), NTR was achieved in 63 patients (10.1%) and STR was present in 39 patients (16.3%). A total of 28 patients experienced recurrences with significant differences in the three subgroups. The strongest predictor of recurrence was the extent of resection, with patients who underwent STR having an almost 10-fold higher risk of recurrence and patients who had undergone NTR having an almost 3-fold higher risk than those treated with GTR. More than 20% of recurrences (6/28) occured after more than 5 years.ConclusionThe degree of resection is an important guide to the interval of follow-up, but long-term follow-up should be considered also in the case of GTR. The majority of recurrences occurs after 3–5 years. Nevertheless, a follow-up of at least 10 years should be carried out.

This study used monoethanolamine (MEA) as an amine-based solvent, which was blended with secondary amines (DIPA), tertiary amines, stereo amines, and piperazine (PZ) to prepare mixed amines at the required concentrations, which were used as the test solvents. To search for the best-mixed amines, a continuous bubble-column scrubber was adopted to explore the performance of mixed solvents presented in this study. The solvent regeneration test was also carried out at different temperatures. The selected factors included the type of mixed amine (A), the ratio of mixed amines (B), the liquid feed flow (C), the gas flow rate (D), the concentration of mixed amines (E), and the liquid temperature (F), each having five levels. Using the Taguchi experimental design, the conventional experimental number could be reduced from 15,625 to 25, saving much time and cost. The absorption efficiency (EF), absorption rate (RA), overall mass-transfer coefficient (KGa), and absorption factor (ϕ) were estimated as the indicators. After the Taguchi analysis, E, D, and C were found to play important roles in the capture of CO2 gas. Verifications of optimum conditions were found to be 100%, 19.96 × 10−4 mole/s·L, 1.2312 1/s, and 0.6891 mol-CO2/L·mol-solvent for EF, RA, KGa, and ϕ, respectively. The evaluated indexes suggested that MEA + PZ was the best-mixed amine, followed by MEA and MEA + DIPA. The solvent regeneration tests for the scrubbed solutions performed at different optimum conditions showed that the heat of the regeneration sequence was in the order of MEA > MEA + PZ > MEA + DIPA with minimum energy required at 110 °C. The individual energy required was also analyzed here.

Published: June 2023

In this paper, we propose for the first time a novel feed approach to a tightly coupled dipole array (TCDA). Firstly, compact zigzagging microstrip feedlines are utilized as baluns to feed our array elements to obtain wideband impedance-matching characteristics. Secondly, this array is designed on ultrathin substrates aiming at obtaining ultra-tight coupling between the dipole arms of two neighboring elements. Some irreplaceable parasitic pads are developed and added to the radiating arms to improve both the impedance and radiation characteristics of the TCDA. With these technologies, a 12 × 12 TCDA prototype is designed, fabricated and measured for verification. The array achieves an impressive impedance bandwidth spanning of 4–18 GHz for S11<−10 dB. Its radiation patterns and realized gain are measured to verify its stable electromagnetic characteristics. Its realized gain is from 15 dB to 25 dB within the operating frequency band. Its efficiency is around 91%. Its measured results show good agreement with simulations.

Authors: Yang Seo-Won , Ma Sung-Ryong , Choi Jong-Bae 
Published: June 2023

(1) Background: The purpose of this study is to investigate the effect of virtual-reality-based hand motion training (VRT) in parallel with the Kinesio Taping (KT) technique on upper extremity function in stroke patients and to present a more effective therapeutic basis for virtual reality training intervention. (2) Methods: First, 43 stroke patients were randomly assigned to two groups: 21 experimental subjects and 22 controls. The experimental group performed Kinesio Taping (KT) on the dorsal part of the hand along with virtual-reality-based hand motion training, and the control group performed only virtual-reality-based hand motion training. The intervention was conducted for a total of 30 sessions over 6 weeks. To evaluate changes in upper extremity function, the Fugl–Meyer Assessment of the Upper Extremity (FMA-UE), the Wolf Motor Function Test (WMFT), and the Motor Activity Log (MAL) (including amount of use (AOU) and quality of movement (QOM)) were evaluated. In addition, the Self-Efficacy Scale (SEF) was evaluated to examine the change in the self-esteem of the study subjects. (3) Results: The experimental group who participated in the virtual reality training in parallel with the KT technique showed statistically significant improvement (** p < 0.01) in the FMA-UE, WMFT, and MAL evaluations that investigate changes in upper extremity function. SEF evaluation also showed a statistically significant improvement (** p < 0.01). A statistically significant difference between the two groups was observed in the evaluation of FMA-UE, WMFT, MAL-QOM, and SEF († p < 0.05), showing that that combined intervention was more effective at improving upper extremity function than the existing VRT intervention. There was no statistical difference between the two groups in the MAL-AOU item, which is an evaluation of upper extremity function (p > 0.05). There was a statistically significant difference between the two groups in the amount of change in upper limb function (†† p < 0.01). (4) Conclusions: It was confirmed that virtual-reality-based hand motion training performed in parallel with the KT technique had a positive effect on the recovery of upper extremity function of stroke patients. The fact that the KT technique provided stability to the wrist by assisting the wrist extensor muscles appears to have improved the upper extremity function more effectively than VRT alone.

Juan Goytisolo con Edward Said: Por una tra(d)ición recomenzada
Authors: Hidalgo Nácher Max 
Published: June 2023

Juan Goytisolo ha sido uno de los escritores que más ha hecho, en el siglo XX, por abrir la historiografía y la literatura nacional a corrientes que exceden la estrechez de un marco esencialista y tradicionalista en el cual no es difícil detectar herencias nacional-católicas y franquistas, pero también provenientes del pasado imperial español y del mito que lo constituye. Este ensayo aborda un cierre, emparentado tradicionalmente, y muchas veces hasta nuestros días, con el discurso del Hispanismo, a partir del trabajo historiográfico y literario llevado a cabo por Goytisolo. Para ello, nos apoyaremos parcialmente en algunas reflexiones de Edward Said, e indicaremos algunas analogías, tal como señala Sebastian Faber, entre Hispanismo y Orientalismo.
L’occupation des versants du col du Petit-Saint-Bernard au Néolithique : premier bilan des données acquises lors des campagnes de sondages du programme Alpis Graia
Authors: Rey Pierre-Jérome , Moulin Bernard 
Published: June 2023

A great test pits program led on both hillsides of Little-St-Bernard pass allowed to discover 11 sites busy from average and final
Neolithic, as well as a series of indications concentrated in the same zone or totally isolated, the dating of which is often more
difficult. The altitudinal distribution of these data presents a tripartition which coincides with lower half of the mountain floor, the superior fringe of the same floor, then superior half of the subalpine and the transition with the alpine floor. A basic typology of the
installation contexts allows to distinguish perched sites which are hyper majority at the foot of hillside, open sites very scattered
at various height and shelters under rock often small which were met only in the superior heights. The presence of sites distant from the main axis of communication in heights averages and especially superiors show that traffic and their control is not the only motivations of the land use. The highlighting of open sites distant from the way pass could give evidence from the average Neolithic of the first attempts of farms on projecting ledges well exposed until 1 600 m of height. Facilitated by the realization of
a large number of radiocarbons dating, the understanding of the Holocene pedo-sedimentary dynamics allows to propose the existence of sedimentary truncations particularly marked in bass and in high height, connected to the development of the anthropic
activities. The permanent character of the low height establishments cannot be demonstrated and does not seem very probable. These observations take away us from the proposed Neolithic occupation model in Valais. The sometimes-delicate identification of
poor levels in remains but marked well in the thickness of the sedimentary deposits, but also the size relatively reduced sites and their terracing altitudinal rather regular, seem compatible with the hypothesis of relay on routes seen frequently regularly by small groups of people, maybe in connection with mainly pastoral activities. The exploitation of the local mineral resources seems to intervene only in an opportunist and limited way. Finally, our data do not allow to give to the Little-St-Bernard pass an important role in the alpine traffic of artefacts in green rock native of the Italian hillside.

The coastline of Thonon-les-Bains and its hinterland provide a favourable framework to the spatial and diachronic analysis of land use during Protohistory. This synthesis is based on the study of old finds and the results of recent rescue operations, in an area between the Dranse and Redon rivers. About 15 sites form a relatively well-documented micro-region, extending from the piledwellings
village of Rives 2 to the settlements and cemeteries stepped on glacial terraces, on the marshlands filling the sinkholes of “ Aviet” in Allinges, and of “ Versoie” next to the Genevray.
L’habitat de la colline Saint-Marcel du Pègue (Drôme) du IXe au VIIe siècle avant notre ère
Authors: Serrières Loïc 
Published: June 2023

The protohistorical settlement of the Saint-Marcel hill at Le Pègue was excavated for thirty years. Data collected by Charles
Lagrand and Jean-Jacques Hatt integrated the different European studies of the time about Iron age. Today, these data can be questioned in the context of current research. This requires first to return to the artefacts, especially the ceramic artefacts. This paper focuses on the first archeological layer (layer F) through the ceramic remains collected in the survey n° 8. It highlights the presence of different chronological sequences, and places particular emphasis on the period by far the most represented, the Bronze final IIIb, and unusual items assigned to an early phase of Iron age.

The aim of this research is to analyze bankruptcy prediction using the Altman Z-Score method at PT. DSSB for the 2019-2021 period. This type of research is descriptive quantitative. Using secondary data with the research population of the financial statements of PT. DSSB period 2019–2021. The research sample is the balance sheet financial statements and profit/loss reports for the 2019–2021 period. Data analysis used analysis of financial performance ratios and bankruptcy prediction analysis Altman Z-Score (Modified Altman). The results show that from the calculation of financial performance, the liquidity ratio is below the industry standard due to an increase in trade payables in each period. The activity ratio on the company's total turnover ratio can maximize the use of assets, the working capital turnover ratio shows a negative number because the working capital owned is not enough to finance sales activities. The profitability ratio is below the industry standard due to the high cost of goods sold and high general administrative costs, as well as other expenses. In calculating the Z-Score analysis, it is always in a dangerous zone, which is a condition where a company experiences financial difficulties with high risk.

Постановка задачи. Рассматривается процесс увеличения интенсивности турбулентного перемешивания в пристенной части пограничного слоя при движении теплоносителя в модифицированном гофрированном канале пластинчатого теплообменника. Необходимо при расчете коэффициента теплопередачи учитывать уровень пульсаций скорости воздействующих на составляющие вектора скорости теплоносителя в пристенном слое. Результаты. С помощью программного комплекса MatlabSimulink получены графики переходных процессов, протекающих в пластинчатом теплообменном аппарате с оригинальными модифицированными пластинами. Установлено, что нанесение сферических углублений на площадки между рифлений способствует интенсификации теплообменных процессов. Выполнено математическое моделирование в противоточном пластинчатом аппарате. Выводы. Результаты исследования позволяют сделать вывод о существенном положительном влиянии турбулизаторов сферической формы на теплообменные пластины с гофрированной поверхностью. Такое сочетание способствует увеличению степени турбулизации теплоносителей в двух контурах пластинчатого теплообменника.
Statement of the problem. The process of increasing the intensity of turbulent mixing in the near-wall part of the boundary layer during the movement of a coolant in a modified corrugated channel of a plate heat exchanger is ivestigated. Whilecalculating the heat transfer coefficient, it is essential to take into account the level of velocity pulsations affecting the components of the coolant velocity vector in the near-wall layer. Results. Using the MatlabSimulink software package, graphs of transient processes occurring in a plate heat exchanger with original modified plates were obtained. It has been established that the application of spherical recesses to the areas between the corrugations contributes to the intensification of heat exchange processes. Mathematical modeling has been performed in a countercurrent lamellar apparatus. Conclusions. The results of the study allow us to conclude that spherical turbulators have a considerable positive effect on heat exchange plates with a corrugated surface. This combination contributes to an increase in the degree of turbulence of the heat carriers in the two circuits of the plate heat exchanger.
