Authors: Fortune Jennifer , Norris Meriel , Stennett Andrea , Kilbride Cherry , Lavelle Grace , Hendrie Wendy , DeSouza Lorraine , Victor Christina , Ryan Jennifer Mary 
Published: December 2021

Background: Identifying correlates of physical activity (PA) for people with multiple sclerosis (MS) is essential to design effective PA interventions.Methods: Participants completed a battery of questionnaires and wore an ActiGraph accelerometer. Light physical activity (LPA) and moderate-to-vigorous physical activity (MVPA) (min/day) were calculated. Associations were examined using multiple linear regression adjusted for demographic and clinical confounders.Results: Fifty-eight adults with MS participated (mean ± SD age: 56.8 ± 9.2 yr; 67% women). MS type was associated with time in LPA. Participants with secondary progressive MS (B = −54.0, 95% CI −84.7 to −23.3) and primary progressive MS (B = −42.9, 95% CI −77.5 to −8.3) spent less time in LPA than those with relapsing remitting MS. Walking capacity, assessed using the 12-item MS walking scale (MSWS-12), was associated with time in MVPA (B = −0.36, 95% CI −0.72 to −0.01).Conclusion: This work identifies walking capacity and type of MS as correlates of PA, which may indicate development of interventions to promote PA.

Introduction: The recent report issued by the MHRA indicating an association of Sodium glucose linked transporter type 2 (SGLT2) Inhibitors with the contraction of Fournier's Gangrene (FG), has been drawn with insufficient supporting evidence and without an adequately powered study to make any meaningful assertions or recommendations. We aimed to look specifically at the currently available dataset used to link SGLT2 Inhibitors to FG and highlight what conclusions or inferences can meaningfully be made, in particular the power of any study that would be required to make sensible conclusions.Methods: World literature review of SGLT2 Inhibitors and FG was performed. With a subsequent 10-year review of cases of FG seen in a regional burns and plastics centre. Data was collected retrospectively from the coding department at Whiston Hospital for all patients with necrotising fasciitis. An electronic document management system was used to identify patients with FG specifically as well as their diabetes state and medication history.Results: Seventy-eight patients were admitted with FG, of whom 32 had diabetes mellitus (DM). Of those with DM none was taking an SGLT2 Inhibitor, 17 patients were taking metformin, a further nine patients were taking a second line medication and 14 required insulin injections.Discussions: DM is a known major risk factor for FG, which is clearly observed in our patient cohort. The risk of patients with DM developing FG is irrespective of the medication patients are taking. The current articles and reports published have little ground to claim an association between SGLT2 Inhibitors and FG and are missing the crucial message that needs to be conveyed to the public: that DM is a major risk factor for FG and patients suffering with diabetes need to be extra vigilant.

Published: December 2021

Abstract
The operational accuracy of the dosing system of the potato planting machine influences the planting plant spacing, and indirectly the crop yield. The operating accuracy depends on the design of the dosing system, its kinematics and the forces acting on the planting tubers. This dissertation presents the force vectors acting on the potato in the dosing system of the guided clamping finger type potato planting machine and their spatial motion during the dosing process. Examination of the vectors reveals the improved possibilities of tuber fixation.
MP-9S Industrial Manipulator Handling and Scrapping Tasks in Industrial Environments
Authors: Józsa Roland Osszián , Erdei Timotei István , Kapusi Tibor Péter , Tóth Szabolcs , Husi Géza 
Published: December 2021

Abstract
The main goal of the project was to carry out a handling task using a color sensor and thermal sensor, as well as an industrial robotic unit. The selection by color made it possible to represent the sub-process of the production of a sample, where each color can be matched to the corresponding or rejected product. The function of the thermal sensor is to show the delay function for the pro-cess, which occurs when the product does not reach a point in the process at the wrong tempera-ture and needs cooling between the two workflows. The thermal sensor and color sensor were pro-grammed using the ATmega microprocessor, while the manipulator was controlled with industrial PLC. The completed project will serve educational purposes in training for students.

Authors: Kun Krisztián , Sárkány Tamás 
Published: December 2021

Abstract
MotoStudent is an engineering and economic competition for students to build a motorcycle that will take part in a real race on the Motorland Aragon track in Spain. The Kenji Racing Team, a student team from John von Neumann University, has been participating in this competition since 2016. The design of the motorcycle must be accurately documented towards to the competition organization, and economic and engineering tasks must be solved for the teams. In terms of engineering work, the development of innovation applied on the electric motorcycle is of paramount importance. Nowadays, one of the most popular development areas in motorsport is aerodynamics. Nevertheless, there are few studies about active aerodynamic systems. In our research we present the aerodynamics of motorcycles and the effect of passive and active wing systems on driving dynamics. With this knowledge, we detail the design steps of an active wing system.

Abstract
Cardiovascular disease has been decimating humanity for decades. In vivo examination of blood vessels is of great help in the development of numerical models and simulations that can help physicians significantly improve sufferers’ quality of life. For such models, the different mechanical characteristics of the vessels are the input data. Several such mechanical properties of the vessels, such as modulus of elasticity and tensile strength, are determined by a tensile test. In the course of our research, an experimental device was developed and tested which is suitable for biaxial tensile tests of blood vessels, which we present through the examination of chicken blood vessels.

Authors: Nemes-Károly István , Kocsis György , Szebényi Gábor 
Published: December 2021

Abstract
In our work, we designed a new metal-polymer shoulder implant system that fully meets today’s requirements - minimal invasive technology, a high degree of modularity - and can be personalized as needed. At the same time, its production does not exceed the currently available production technologies. Also, the data and parameters which are needed to design the tailor-made construction are easily accessible, as we have chosen a device that is widespread and commonplace in medical diagnostics and available in any hospital. Furthermore, we have tried to make our system as easy and fast to authorize as possible because it is challenging to place medical devices on the market, especially implants. We have tried to create the cheapest, most economical system and in addition, we wanted to gain the trust of implant specialists, as we incorporated their insights and experiences into our construction through continuous consultation.

Published: December 2021

Abstract
Thanks to technological development, and the more and more strict environmental regulations, electric and hybrid vehicles are playing an increasingly important role in road transport. An important part of these vehicles is the electric motor, which has several different types that are applied in modern vehicles. To perform the simulation of the motors, it is important to measure their basic electromagnetic and dynamic parameters, since they are usually not provided by the manufacturers. For the above measurements a complex measuring system is needed. This motor test bench is also suitable for the static and dynamic testing of different types of electric motors. In this publication the layout of our own developed test bench is presented.
Analyses of River Oil-Spills and Actual Solving Methods
Authors: Zsombor Kisfaludi-Bak 
Published: December 2021

Abstract
Nowadays, there is an increasing emphasis on the problem of water quality. Of the many polluting effects, oil pollution is perhaps the most harmful, but its effects are being studied mostly on large seas and oceans worldwide. In the case of Transylvania and probably the entire country, pollution of rivers by oil – based on yearly occurrence – has a larger effect than that of sea pollution. Every year we observe 40-55 such water pollution events, therefore, analysis and investigation of solution methods is of great importance. This paper attempts to shed light on this issue, presenting also the method currently used by the Romanian Water Authority.

Published: December 2021

Un análisis geomorfológico y sedimentológico fue realizado en el sector medio del Valle de Pueblo Llano con la finalidad de comprender la génesis de los sedimentos y geoformas cuaternarias presentes en el área. Cuatro sectores con características morfológicas y sedimentológicas distintivas fueron identificados: (i) depósitos en masa de flujos de detritos con una expresión superficial cónica interpretados como abanicos aluviales, (ii) depósitos de flujos unidimensionales que constituyen terrenos relativamente planos con bajas pendientes característicos de terrazas fluviales, (iii) depósitos de diamicton que constituyen un conjunto de lomos y depresiones en forma de arco asociados a un complejo de morrenas frontales, y (iv) depósitos de flujos unidimensionales que conforman terrenos con forma de lomos asimétricos, asociados a condiciones fluvio-glaciares. Estos resultados ponen en evidencia que los glaciares asociados a la Glaciación Mérida en el Valle de Pueblo Llano, alcanzaron elevaciones al menos 300 m más bajas que las reportadas previamente en la literatura para los Andes de Mérida. Además, sugieren que otros valles glaciares presentes en los Andes de Mérida pudieron haber experimentado fenómenos similares.

Palabras clave: Andes de Mérida, Geomorfología y Sedimentología, Morrenas, Glaciación Mérida, Pueblo Llano.

Abstract:
A geomorphological and sedimentological analysis was carried out in the Middle reach of the Pueblo Llano Valley to understand sediment genesis and quaternary geoforms present in the area. Four zones with distinctive morphological and sedimentological characteristics were identified: (i) mass deposits of debris flow with a cone-shaped surface interpreted as alluvial fans, (ii) unidirectional flow deposits with relatively flat topography, with little slope, characteristic of fluvial terraces, (iii) arc-shaped diamicton deposits that constitute a set of crests and valleys, associated to a complex of frontal moraines, and (iv) unidirectional flow deposits that form terrains with the shape of asymmetric ridges, associated to a fluvio-glacial conditions. These results show that the glaciers of the Mérida Glaciation in the Pueblo Llano Valley reached elevations of at least 500 m lower than those previously reported in the literature for the Mérida Andes. In addition, they suggest that other glacial valleys present in the Andes of Mérida might have experienced similar phenomena.

Efecto del pH y Sales Inorgánicas en la Degradación de Colorantes Industriales por Pleurotus Djamor
Authors: Peñafiel García Mario Javier , Romero Zambrano Cristhopher Alexander , Moreira Mendoza Carlos Antonio , Rosero Delgado Ernesto Alonso 
Published: December 2021

En la presente investigación se planteó el uso de la cepa Pd318 del hongo Pleurotus djamor como agente biorremediador, con el objetivo de evaluar su capacidad para degradar el colorante reactivo azul 19 (A19). Para ello se estudió la influencia que tienen cinco sales inorgánicas en el crecimiento y actividad lignolítica del hongo. Un cribado de sales inorgánicas en placa determinó que las sales CaCl2.2H2O y MnSO4.5H2O tienen mayor influencia en el desarrollo micelial y actividad lignolítica de la cepa. Ensayos de fermentación líquida (FEL) con diferentes combinaciones a distintas concentraciones de las sales de calcio y manganeso permitieron demostrar la capacidad de degradación del colorante azul 19 a los 7 días de fermentación líquida a temperatura ambiente y agitación constante. Los máximos porcentajes de degradación del colorante fueron obtenidos con las combinaciones A1B1 y A2B1 con 43,47% y 41,36%, respectivamente. Se observó que a un pH de 5 unidades se favorece la degradación del colorante. Los estudios en placa señalaron que la adición de sales de calcio y manganeso en 10 días de incubación favorecieron el desarrollo micelial y la actividad lignolítica de Pd318, mientras que en un sistema FEL de 7 días, únicamente la adición de manganeso influye favorablemente a la actividad lignolítica del hongo y en consecuencia a su capacidad de degradación de azul 19.

Abstract

In the present investigation, the use of the Pd318 strain of the Pleurotus djamor fungus as a bioremediation agent was proposed, with the aim of evaluating its ability to degrade reactive dye blue 19 (A19). For this, the influence of five inorganic salts on the growth and lignolytic activity of the fungus was studied. A plate screening of inorganic salts determined that the CaCl2.2H2O and MnSO4.5H2O salts have a greater influence on the mycelial development and lignolytic activity of the strain. Liquid fermentation tests (FEL) with different combinations at different concentrations of the calcium and manganese salts allowed to demonstrate the degradation capacity of the blue dye 19, after 7 days of liquid fermentation at room temperature and constant stirring, the maximum degradation percentages of the dye were obtained with the combinations A1B1 and A2B1 with 43.47% and 41.36% respectively. It was observed that at a pH of 5 units the degradation of the dye is favored. The plate studies indicated that the addition of calcium and manganese salts in 10 days of incubation, favored mycelial development and the lignolytic activity of Pd318, while in a 7 day FEL system, only the addition of manganese favorably influenced the lignolytic activity of the fungus and consequently its ability to break down blue 19.

Keywords: Blue dye 19, dye degradation, lignolytic enzymes, Pleurotus djamor.

Abstract
The concrete obtained from finely ground glass is a line of investigation to new materials, based on the saving of cement and in turn on the reduction of carbon dioxide to the atmosphere to obtain a more efficient and sustainable construction material.
In order to find a solution for the manufacture of concrete, the use of finely ground glass as a partial replacement of cement is one of the alternatives to integrate it into the construction process, whose aim is to reduce the use of non-renewable raw materials, using recycled materials with excellent strength and durability characteristics. In this research, the compressive strength of concrete was studied, using finely ground glass, replacing it in percentages of 5%, 10% and 15% in partial replacement of cement. Conventional concrete test pieces and concrete test pieces with the addition of finely ground glass were produced and each tested test piece was tested for the compressive strength of the concrete within a maximum curing time of 56 days
A comparison was made between aggregate concrete and concrete with finely ground glass percentages, concluding that glass replaced at 15% as a partial replacement for cement decreases its compressive strength.

Index Terms — finely ground glass, compressive strength, concrete, addition, cement.
