: This study is concerned with spatial visualisation and its possible inferences as a necessary ability in French engineering education. It is completed as part of a French research programme, which aims at better understanding how multi-purpose 3-D modelling software is used by learners at different levels of schooling. Spatial ability may be measured thanks to paper tests and predicts choices and success in science, technology, engineering, and mathematics education and professions. It is often described as an ability composed of two factors, namely spatial orientation and spatial visualisation. The latter can be further developed into mental rotation and mental transformation. In order to evaluate the spatial visualisation skills of first-year students in a French engineering school specialised in mechanics, the Revised Purdue Spatial Visualization Tests: Visualization of Rotations, the Mental Rotation Test, which both aim at measuring mental rotation, and the Mental Cutting Test, which aims at measuring mental transformation, were administered to 137 engineering freshmen in September 2018. This data collection was completed with a selection of demographics and academic assessment scores. The purpose of this article is to explore, by carrying out an analysis of variance, how these students’ spatial visualisation skills can be related to individual characteristics and how they contribute to academic performance.

We describe our four NMT systems submitted to the IWSLT19 shared task in English→Czech text-to-text translation of TED talks. The goal of this study is to understand the interactions between document-level NMT and domain adaptation. All our systems are based on the Transformer model implemented in the Tensor2Tensor framework. Two of the systems serve as baselines, which are not adapted to the TED talks domain: SENTBASE is trained on single sentences, DOCBASE on multi-sentence (document- level) sequences. The other two submitted systems are adapted to TED talks: SENTFINE is fine-tuned on single sentences, DOCFINE is fine-tuned on multi-sentence sequences. We present both automatic-metrics evaluation and manual analysis of the translation quality, focusing on the differences between the four systems.

The preliminary phytochemical analysis of extract of Spermadictyon suaveolens was performed and its effect on oral glucose tolerance in streptozotocin induced diabetic rats studied. 1 week after the administration of streptozotocin, diabetic rats received herbal extract orally at dose 500 mg/kg body weight for 28 consecutive days. Oral glucose tolerance test was performed on overnight fasted rats on day 28. Blood samples were collected prior to glucose administration and at 30, 60, 90, 120 minutes after glucose loading and plasma glucose level was measured for all the samples. The preliminary phytochemical analysis of extract of roots of Spermadictyon suaveolens showed the presence of carbohydrates, flavonoids, glycosides, tannins and phenolic compounds. Extract of roots of Spermadictyon suaveolens improved oral glucose tolerance in streptozotocin induced diabetic rats.

: Soft Sensors (SSs) are inferential models used in many industrial fields. They allow for real-time estimation of hard-to-measure variables as a function of available data obtained from online sensors. SSs are generally built using industries historical databases through data-driven approaches. A critical issue in SS design concerns the selection of input variables, among those available in a candidate dataset. In the case of industrial processes, candidate inputs can reach great numbers, making the design computationally demanding and leading to poorly performing models. An input selection procedure is then necessary. Most used input selection approaches for SS design are addressed in this work and classified with their benefits and drawbacks to guide the designer through this step.

In the area of computer system programming, theoretical concepts between hardware and software solutions need to be explained. Even though this topic is highly practical, as it covers the theoretical concepts of any modern machine like computers and smartphones, it is still difficult to provide easy access to any practical experience as the gap between current hardware solutions and basic implementation of operating system processes is too large for undergraduate students. As it is not possible to test those concepts in an applied way, we aim to provide an interactive web simulation framework called SysprogInteract. SysprogInteract provides modern animations of the behaviour of single computer components as well as more complex ones that show the relationship between components. The goal is to provide high quality media content, accessible any time to any student, providing individual feedback and fostering exchange between students through the overall platform. This paper presents the first animated hardware component (CPU) of SysprogInteract, visualizing the concept of scheduling processes. Based on this tool, we show how it can be integrated within a lecture with more than 800 students at the TU Berlin, Germany. Furthermore, we present a case study with 59 students, showing a high usability through the System Usability Scale with a score of 79.5; more than 86% of students responded they would use this application for exam preparations. Additionally, we present the overall concept of the platform, which is ongoing work.

A total of 49 different clinical samples (urine n=30, stool n=10, and blood n=8) were collected from patient admitted to the Al-Sadder medical City in Al-Najaf Governorate-Iraq. The results demonstrated that 49 specimens (100%) were diagnosed as E. coli by cultural, biochemical characteristics and Vitek2® system. Polymerase Chain Reaction has been used to detect of some genes which coding antimicrobial resistance in E. coli isolates. Regarding genes that responsible for ESBL enzymes (blaCTX-M, blaOXA and blaTEM), the current results proved that blaTEM genes have highest rate (97.95%) followed by blaTEM and blaOXA (93.75%) for each.

: An important challenge for our society is the transformation of traditional power systems to a decentralized model based on renewable energy sources. In this new scenario, advanced devices are needed for real-time monitoring and control of the energy flow and power quality (PQ). Ideally, the data collected by Internet of Thing (IoT) sensors should be shared to central cloud systems for online and off-line analysis. In this paper openZmeter (oZm) is presented as an advanced low-cost and open-source hardware device for high-precision energy and power quality measurement in low-voltage power systems. An analog front end (AFE) stage is designed and developed for the acquisition, conditioning, and processing of power signals. This AFE can be stacked on available quadcore embedded ARM boards. The proposed hardware is capable of adapting voltage signals up to 800 V AC/DC and currents up to thousands of amperes using different probes. The oZm device is described as a fully autonomous open-source system for the computation and visualization of PQ events and consumed/generated energy, along with full details of its hardware implementation. It also has the ability to send data to central cloud management systems. Given the small size of the hardware design and considering that it allows measurements under a wide range of operating conditions, oZm can be used both as bulk metering or as metering/submetering device for individual appliances. The design is released as open hardware and therefore is presented to the community as a powerful tool for general usage.

Conducted research devoted to the study of potential mechanisms of action implementation endotelioproteсtion 4- hydroxy3,5-di-tretbutyl cinnamic acid in experimental conditions simulated cerebral ischemia in rats. The research found that the cerebral ischemia in rats is accompanied by the development of endothelial dysfunction, expressed in increasing the concentration of asymmetric dimethylarginine, nNOS, iNOS and PKC, as well as reducing the concentration of eNOS.
