Ramsey Hunt syndrome in the child: case report and treatment approach

Herpes zoster is a manifestation of the reactivation of an infection after chickenpox. One of the manifestations of herpes zoster is Ramsey Hunt syndrome, which develops when the ganglion of the VII pair of cranial nerves is involved in process. Diagnosis of Ramsey Hunt syndrome is often based on a combination of a rash in the outer ear and peripheral paresis of the facial muscles. The article describes a rare clinical case of herpes zoster in a child without clinical signs of immunodeficiency, with the development of unilateral paralysis of the facial muscles, pleocytosis in the cerebrospinal fluid. Therapy was performed with a combination of acyclovir and high doses of methylprednisolone with a good clinical effect. It is first mentioning of deviations in the immune status (decreased concentration of the number of markers of naive T‑lymphocytes (TREC)) were revealed, which could be associated with the development of herpes zoster in a child.

Ultrasound and Sialogram Correlates to Parotid Immunoglobulin G4-Related Disease

Immunoglobulin G4 (IgG4)-related disease is an immune-mediated disorder that commonly manifests in the salivary glands. As a recently described disorder, the description and classification of IgG4-related disease is an ongoing process. Diagnosis of IgG4-related disease requires integration of clinical history, histopathology, and radiographic findings, including ultrasonography and sialography. In this case report, we correlate parotid ultrasonographic and sialographic findings in a patient with proven IgG4-related disorder confirmed from analysis of previous submandibular gland resections. We aim to highlight the utility of multimodality imaging in the diagnosis of IgG4-related disease.

Ion and Radical Characteristics (Mass/Energy Distribution) of a Capacitively Coupled Plasma Source Using Plasma Process Gases (CxFy)

We constructed a capacitively coupled plasma (CCP) source and installed various diagnostic tools to perform process diagnosis using a plasma process gas (CxFy). We obtained the energy and mass distributions of the ions and radicals from Ar, C4F8/Ar, and C4F6/Ar plasmas. The energy distribution of the ions incident on the substrate was controlled using the self-bias voltage, and the ion energy was found to be inversely proportional to the mass. The measured species and density of the ions and radicals can help understand plasma process results as they provide information about the ions and radicals incident on the substrate.

ORGANIZATION AND METHODS OF RESEARCH AND EXPERIMENTAL WORK ON TRAINING OF PRIMARY SCHOOL TEACHERS IN PEDAGOGICAL COLLEAGUES FOR INTEGRATED TEACHING OF STUDENTS

The article reveals the peculiarities of the organization and methods of research and experimental work on the preparation of primary school teachers in pedagogical colleges for integrated student learning. The purpose of the article is to describe the general methodology of the pedagogical experiment and present the generalized results of experimental work. Achieving the goal involved the use of the following methods: empirical – observation, questionnaires, testing, interviews, the method of expert assessment to determine the state of readiness of future primary school teachers for integrated learning of students; pedagogical experiment to test the effectiveness of the implementation of pedagogical conditions and models of the studied process. Diagnosis of the readiness of future primary school teachers for integrated learning of students involved conducting research and experimental research in several stages: ascertaining, formative, control. To assess the levels of readiness of future primary school teachers for integrated learning, a system of criteria and indicators has been developed taking into account the structure of students’ preparing for professional activity and its result: in the context of our study − readiness of college students − future primary school teachers for integrated learning. The use of a set of methods and techniques of diagnosis allowed to determine the initial level of readiness of future primary school teachers for integrated student learning; to confirm the effectiveness of the implementation of the developed model and pedagogical conditions for the preparing of primary school teachers in pedagogical colleges for integrated student learning. The obtained results of the pedagogical experiment made it possible to develop methodological recommendations for teachers of pedagogical colleges on the introduction of pedagogical conditions and models of training future primary school teachers in pedagogical colleges for integrated student learning.

Wastewater COD characterization: RBCOD and SBCOD characterization analysis methods

Wastewater characterization is the basis for process design and operation optimization of wastewater treatment plants (WWTPs). In this work, a comprehensive study of the respirometry method has been performed to evaluate the biodegradable organic matters of wastewater. First, the optimal initial substrate to biomass ratio (S0/X0) was confirmed. Second, under the optimal S0/X0, the degradation curves of wastewater carbon oxygen demand (COD) components rapidly biodegradable COD (RBCOD) and slowly biodegradable COD (SBCOD) were obtained. Third, the Mann–Kendall test was performed to confirm the time point (t2) when endogenous respiration levels were reached, and the hydrolysis model was used to determine the time point (t1) of the SBCOD degradation stage. Considering the results, an adequate wastewater COD characterization method for RBCOD and SBCOD has been proposed. This study provides strong support to carry out effective and feasible process design, process diagnosis and optimization capability, can help achieve refined and stable operational management of WWTPs.

Who is Best at Mediating a Social Conflict? Comparing Robots, Screens and Humans

The impacts of various mediation platforms on negotiation outcomes and perceptions are compared in this article. The mediator platforms contrasted were a (teleoperated) Telenoid robot, a human, and a computer screen. All of these platforms used the same script for process diagnosis, analysis, and advice on how to resolve an impasse in a simulated high-tech company de-merger negotiation. A fourth experimental condition consisted of a no-mediation control. More agreements and more integrative agreements were attained by the robotic platform than by the other types of mediator platforms and the control. Mediation via the Telenoid robot also produced more non-structured agreements, which consisted of decisions made outside of the scenario options. Negotiators in this condition had more positive perceptions of the mediation experience, were more satisfied with the outcome, and thought that the mediator’s advice was more useful. Indirect analyses showed that the outcomes mediated the effects of the conditions on perceived satisfaction. Implications of the findings are discussed in terms of responses to novelty, which include creative and divergent modes of thinking.

Process Diagnosis of Liquid Steel Flow in a Slab Mold Operated with a Slide Valve

Slab molds receive liquid steel from the tundish through bifurcated submerged entry nozzles (SEN) using a slide valve as throughput control. Due to the off-centering position of the three plates’ orifices that conform to the valve to control the steel passage, the flow inside the nozzle and mold is inherently biased toward the valve opening side. In the practical casting, a biased flow induces inhomogeneous heat fluxes through the mold copper plates. The nozzle design itself is also a challenge, and has direct consequences on the quality of the product. A diagnosis of the casting process regarding the internal and external flows, performed through experimental and mathematical simulation tools, made it possible to reach concrete results. The mathematical simulations predicted the flow dynamics, and the topography and levels variations of the meniscus characterized through a full-scale water model. The flows are biased, and the meniscus level fluctuations indicated that the current nozzle is not reliable to cast at the two extremes of the casting speeds of 0.9 m/min and 1.65 m/min, due to the danger of mold flux entrainment. A redesign of the nozzle is recommended, based on the experimental and mathematical results presented here.
