Authors: Fonseca Manuel José , Garcia Jorge Esparteiro , Vieira Bruno , Teixeira Andreia Sofia 
Published: June 2023

Abstract
This study aims to assess the lecturers’ opinions about the use of e-learning tools to support distance and blended learning in higher education in Portugal, evidently reinforced by the COVID-19 pandemic. This research was based on a qualitative methodology, specifically, a focus group with professors from five higher education institutions from different geographical areas in Portugal. The obtained results were analysed along four main dimensions: (1) the level of knowledge of e-learning tools, (2) the reasons for using or (3) not using them, and, finally, (4) the opinion of lecturers on the student assessment process using these tools. The results showed that in addition to the concerns with smooth running classes and the appropriate delivery of the syllabus, the lecturers considered the transition to the e-learning context to have been easy. They noted a high level of literacy in the used tools, believed in the continued use of e-learning in the post-pandemic context, indicated several advantages for those involved in the e-learning context and a majority of limitations related to the time required for the adoption of more tools; and, finally, underlined the student assessment issue, which was pointed out as the most sensitive topic in the whole e-learning context. The study informed on the lecturers’ perspective on e-learning and the used tools and provided insight into their perceived usefulness and benefits for lecturers and students. An especially strong concern was verified on the part of lecturers to optimise e-learning tools to provide better knowledge delivery to students.

Abstract
Using vegetation as a bioindicator in urban and degraded areas is an effective way to assess the status of the environment. In this work, we present the results of a phytosociological investigation of a suburban river and of its surroundings in southern Tuscany (Bestina river and its tributary Bestinino in Asciano, Province of Siena). By means of 94 phytosociological relevés, we identified 34 plant communities belonging to the 17 classes. Six habitats included in the 92/43/EEC Directive, plus two habitats recently proposed for inclusion, were identified, as well as one habitat of regional interest. The study revealed that, despite the high levels of human disturbance, aquatic and herbaceous riparian vegetation is still well-preserved, though mostly represented by stress-tolerant communities. On the contrary, most of the vegetation types not being directly linked to the river dynamic are in poor conservation status. Despite this, some habitats of community interest were detected even in non-riverine sites. Our work provides the basic knowledge for future restoration of the Bestina river and of its surroundings, wished by the Tuscany Region.

Abstract
This descriptive study aims to examine the behavior of dogs diagnosed with hypothyroidism and the potential effect of hormonal treatment. Eight client-owned dogs with clinical hypothyroidism were evaluated using an adapted C-BARQ questionnaire, clinical description, and hematological analysis. Six of the dogs’ behavior was monitored for four months after the treatment initiation. The study found that excitation, whining, and urinating when left alone were frequently observed. Attention-seeking was also a common behavior reported by the owners. The biochemical analysis before the treatment had revealed elevated cholesterol, triglycerides, and alkaline phosphatase levels in the majority of dogs. The study emphasizes the need for prospective studies using a larger sample size to gain further insight into the relationship between hypothyroidism and behavior in dogs. Monitoring changes in behavior over time can provide insight into how thyroid dysregulation may contribute to the onset of certain behavioral patterns. Functional brain imaging and pathohistological brain analysis in dogs with long-term hypothyroidism are also required to confirm the effects of hypothyroidism on canine brain function.

Abstract
The union of different devices in order to obtain a specific response for a process is commonly called a control system. For a control system, it is necessary to have one or more controllers. Among the most used in the industrial sector are the PID and PI controllers. Next to these controllers is the control software. Scilab is a good example of control software. It is characterized as free code software, with no cost for its acquisition, in addition to having a large computational power and integrated tools, such as Xcos, intended for modeling and simulation. For the union with Scilab, there is Arduino. Such a mixture can be used, for example, to control liquid levels in tanks. In this context, the present work aims to study the tank-level control system based on PID and PI controllers through the union between Scilab and Arduino. Phenomenological models were developed based on closed-loop control (feedback control system) of the process with two tanks not coupled with recycle. Furthermore, for comparison purposes, two approaches were used for each process: one considering the saturation of the manipulated variable and the other without the presence of such saturation. At first, there was a need to implement an anti-windup system. For tuning the controller parameters, the ISE method was used, executed through a programming code developed in Scilab. The parameters found for the two systems were tested on a made-up experimental bench. Therefore, using the block diagrams and the method here called “ISE method”, satisfactory values were obtained for the control parameters. These were ratified in the tests carried out in the experimental module. Level control was achieved with greater prominence for the PI controller since there is one less parameter to be tuned and processed by the system. This controller provided results close to the PID controller for cycles up to 50%. In general, the PI controller showed maximum response deviations smaller than the PID, such as deviations of 1.55 cm and 2.40 cm, respectively, for the case with 75% recycle. It was also clear the influence of the saturation of the manipulated variable on the system response, but not on the tuning of the controller parameters.

Abstract
The dominance of plastics in the packaging market is due to their low weight and thickness, which save transportation costs. However, their non-biodegradability poses a significant threat to the environment. Paper, on the other hand, is considered as a safer alternative due to its natural composition and biodegradability. The porous structure of paper limits its application in packaging, and its poor water resistance further restricts its use in humid environments. Therefore, lamination is a method useful tool to improve the barrier properties of paper. Additionally, the researchers are focusing on developing biodegradable and water-based coatings with anti-fat properties as a green alternative to plastic packaging. The impact of a new grease-resistant coating composed of starch, gelatin and sodium alginate on the mechanical properties of paper was investigated through tensile, tearing, and bursting strength tests. The results showed significant improvements in the mechanical properties of the coated paper sheets. Furthermore, the biodegradability test indicated that the paper samples coated with the new composition showed a 50% weight loss after one week of incubation in the soil, and after three weeks, they exhibited 100% weight loss, demonstrating their outstanding biodegradability.

Authors: Fattah Mohammed Y. , Zbar Bushra S. , Al-Kalali Hala H. M. 
Published: June 2023

Abstract
The experimental work of this study deals with the performance of pipe in sand with various responses subjected to incremental static loading where the backfill is reinforced with two types of reinforcement (geogrid and geocell) to investigate the effects of backfill cover. The pipes considered are installed in sand with different densities; i.e., loose, medium and dense sand, and a constant burial depth (2D, where D is the pipe diameter). It was concluded that the maximum deformation occurs at the crown of the pipe. The deformation increases when the sand density decreases. For a burial depth equal to 1.5 D, the maximum strain on the pipe crown increases by about 22.5% when the sand changes from dense to medium and 36.8% when it changes from dense to loose. The vertical stress above a pipe buried in loose sand is reduced by 8.3% when the geogrid width is 2B where B is the footing width, while it is equal to 22% when the geogrid width is B. When a geocell is used, the percent reduction is equal to 62%. The percent reduction in the vertical stress above a pipe buried in medium sand is about 28% when the geogrid width is 2B and 40% when the geogrid width is B and equal to 68% when the geocell is used.
Subglottic Tracheal Stenosis, Resection, And Reconstruction: A Case Report
Authors: Campar Branko , Klepetko Walter 
Published: June 2023

Abstract
Post-intubation stenosis are the most frequent indications for tracheal resection and reconstructions. They are mostly caused postintubation inflated cuff and after distal tracheostomy. 16- year-old female was admitted to thoracic surgery department, General hospital Vienna with the diagnosis of an impossible weaning with a tracheostomy in place. The pre-operative bronchoscopy and MSCT of the neck evaluation revealed a total occlusion of the trachea below the cricoid arch and reaching distally to the level of the tracheostomy (total length approx. 3cm) by means of an acquired tracheostomy-associated tracheal stenosis (Myer-Cotton IV°). The distal trachea was unaffected. Thus, the indication for a surgical repair was set. Tracheal resection through a cervical incision was performed. The pre-existing tracheostomy as well as the stenotic segment was resected (resection length approx. 3.5cm) and a cricotracheal end-to-end anastomosis was performed. Subglottic resection of the trachea is rare, if conducted a good selection of patients performed precise surgical procedures with the support of anesthesia is considered by some to be the procedure of choice for the treatment severe (>70% luminal obstruction).

Published: June 2023

Abstract
Carotid atherosclerosis is a main risk factor for ischemic stroke. Plaque instability is determined by the morphological characteristics of the plaque and can be characterized by immunological biomarkers. The study aimed to examine the connection between serum levels of hs-CRP, fibrinogen, ICAM-1, VCAM-1 and carotid atherosclerosis and the different types of atherosclerotic plaques imaged by ultrasound and magnetic resonance. The study involved 120 patients with carotid atherosclerosis and 33 patients without carotid atherosclerosis. Blood samples were collected to analyze the serum level of hs-CRP, fibrinogen, ICAM-1 and VCAM-1. The ultrasound analysis included detection of atherosclerotic plaques in the internal carotid arteries, measurement of artery stenosis in percentage and determination of plaque types by the classification of Gray-Weales/Gerolacus. A small subset of 30 patients with carotid atherosclerosis performed 3T magnetic resonance imaging. Atherosclerotic plaques were classified into 8 types based on the modified MR classification of the American Heart Association. Significantly higher serum levels of hs-CRP (p <0.001) and fibrinogen (p = 0.018) were observed in patients with carotid atherosclerosis compared to patients without atherosclerosis. Criterion values for hs-CRP > 4.13mg/l and for fibrinogen > 3.6 g/l were associated with the presence of carotid plaques with accuracy of 70%. No relation was observed between the investigated biomarkers, the artery stenosis and the types of atherosclerotic plaques determined by ultrasound and magnetic resonance diagnostic methods. Hs-CRP and fibrinogen are reliable serum markers whose increased serum concentrations are connected with the presence of carotid atherosclerosis.
