Metals play an important role in many biological systems, not to mention that their use in the formulation of drugs with novel modes of action has boosted the investigations aimed at elucidating their reaction mechanisms. At variance with carbon-based (or purely organic) molecules which nowadays may be described rather satisfactorily with molecular mechanics, molecules involving metals cannot do without a proper quantum mechanical treatment of the metal atoms. For this reason, in the last years we have been investigating a wealth of methods ranging from pure quantum mechanical ones to multilayered approaches which allow the calculation of detailed information related to the structure, the dynamics and the reaction mechanisms of metal-based biomolecules or drugs.Metals play an important role in many biological systems, not to mention that their use in the formulation of drugs with novel modes of action has boosted the investigations aimed at elucidating their reaction mechanisms.

The continuous growth of vehicles on the road and the consequent traffic congestion, especially in suburban areas, is a source for major concern. It impacts negatively on the operating costs of infrastructures and on the social and economic life in the surrounding area. From an economic perspective, travel time for the displacement between two junctions of a network is one of the most significant factors to be taken into consideration. On this basis, the designer decides on the level of service and the type of infrastructure to be built and the traveller assesses the alternatives to the existing modes of transport and his willingness to face the associated cost. In Europe, United Kingdom (UK) was the first country to value travel time in the early 1960s. Moreover, until 2011, it contributed to the estimation of the monetary value of time for 60% of international studies within the EU. The UK Department for Transport (DfT) adopts the Transport Analysis Guidance (WebTAG) as useful transport planning and design tool. This paper discusses on the guidelines and software tools adopted for the economic evaluation of transport interventions in UK and Italy, highlighting particularly, the values and methods for estimating the value of time (VOT) in both countries. We propose a strong integration of the two models taking into account the numerous parameters examined in UK and at the same time the method’s easy applicability for countries with different development conditions and needs.

We live in an era when we are significantly confronted with new social trends which affect the living environment, sustainable life, migration processes, global social changes, and economic innovations, as well as new technologies and more efficient use of artificial intelligence. We perceive the future not only as a scientific and technological challenge, but also as an issue of ethical importance and potential ethical risks. Therefore the civilisation changes, such as the adaptation to the parameters of a new society under Industry 4.0, call for ethical caution and moral sensibility in order to reduce, or even eliminate, potential negative impacts on humans and their existential conditions. The use of robotics and artificial intelligence in various areas, such as in the field of law, education, construction of smart cities or public administration, gene technologies, housing, productivity, social services, industry, and the like also poses a new requirement. For example, the demand will grow for creative people, professionals having understanding for a human in a new environment, in everyday contact with artificial intelligence, new functioning of institutions, business transformation, and the entire social systems. They should be individuals able to response, in a creative manner, to specific situations and needs, new forms of self-realization. There will be a radical change in the area of personalisation, this including both the education and the personalised and individualised service, responses to individual requirements of a citizen, client, or consumer. Modern era was based on mass production and social revolutions. The social changes and shifts in values are mirrored by intellectual authorities, such as G. Lipovetsky who emphasises the necessity to adopt new ethical approach in relation to the new social paradigm.

Letrinhas is an information system created by the Polytechnic Institute of Tomar (Portugal), in partnership with a School Grouping (Portugal), to give support to elementary school children with reading difficulties. The software can be used on mobile devices, such as a tablet, and allows the evaluation and improvement of reading fluency. By promoting the development of students’ reading skills, it contributes to the development of autonomous readers and consequently to the improvement of school results. In order to evaluate the importance of Letrinhas software in the process of reading (children from 2nd and 3rd grade, with a mean age of 7/8 years old), two independent samples were collected, consisting of students from several primary schools. A sample is made up of students who have learned from Letrinhas (experimental group) and the other sample consists of students who have learned to read through the classic process (control group). In the students’ learning process there are two essential reading components: fluency and precision. To statistically compare the data gathered for the variables Fluency Index and Precision Index, in both groups (experimental and control), confidence intervals and (non)parametric tests were used. The differences between the two teaching methods of reading, observed in graphs and in the values of some descriptive statistical measures, are statistically significant (also the values obtained for the effect sizes measures are considerable). The positive impact of the Letrinhas software on the fluency and precision of reading, empirically identified by teachers, was statistically confirmed.Letrinhas is an information system created by the Polytechnic Institute of Tomar (Portugal), in partnership with a School Grouping (Portugal), to give support to elementary school children with reading difficulties.

In several academic activities students experience a considerable stress in their daily life. Stressors may affect the mental and physical health of college students, leading some of them to the burnout syndrome. To evaluate this syndrome in students at Arizona State University (ASU), USA, a survey was conducted using a questionnaire previously developed, with ordinal variables. A theoretical Structural Equation Modeling (SEM) was proposed and the estimated model was obtained applying the Partial Least Squares (PLS) approach. Based on the PLS-SEM path coefficients, the latent construct behavioural stress has a direct effect on distress and insecurity, and an indirect effect on both quantitative demands and academic burnout. Both mediator constructs quantitative demands and distress have a direct effect on the academic burnout in students. A multi-group analysis was also conducted to compare the path coefficients of the estimated model by gender, but the differences are not statistically significant. These results allow a better understanding of burnout syndrome in ASU college students, which can severely limit their psychosocial well-being and performance.In several academic activities students experience a considerable stress in their daily life.

Due to the fact that Antarctica is one of the least polluted places on Earth, it is a perfect place to observe the spread of global pollution. Therefore, research conducted on this continent is important due to the possibility of investigating the type of pollution and their way of transport. This work considers presence of organic contaminants in Maritime Antarctica in unexplored until now, Lions Rump headland. Qualitative and quantitative analysis of samples were carried out in order to determine the content of analytes such as polycyclic aromatic hydrocarbons (PAHs). Among all determined PAHs in water samples the highest concentrations was observed for naphthalene and anthracene, which is the result of their higher volatility in comparison to the High Molecular Weight PAHs. The presence of PAHs in the water environment may constitute potential negative effect on Antarctic ecosystem and it should be investigated in detail. Moreover, possibility of undertaking various actions reducing contaminants emission are also very important. We hope that improved fossil fuel economy, and not only on the local scale, would help reduce PAH levels in Maritime Antarctica.Due to the fact that Antarctica is one of the least polluted places on Earth, it is a perfect place to observe the spread of global pollution.

In this survey, we investigate the usage of Trajectory log data in a single case of a patient undergoing Stereotactic Radiosurgery (SRS) treatment. A dedicated linear accelerator machine Varian TrueBeam STX was used. The software was developed for analyzing the log files which were created by the machine when a certain plan was performed in treatment mode or QA mode. Four plans were created with 7 no-coplanar fields. Additional structures must be added by the physicist in the contouring section in order to optimize the plans. Dosimetry equipment ArcCHECK was used to verify the dose distribution for the created plan. The evaluation of γ passing rate (%GP) from the Trajectory log was done for each field separately using Pylinac v.2.2.6 API (application programing interface) for Machine quality control. It was shown that for one of the plans the values of %GP in some of the fields were very low with about less than 15% passing and at the same time the ArcCHECK shows a good %GP of about 90%. When verifying the plans using the analyzed Trajectory log files it can be detected if there are problems with the rotation of the collimator, the positioning of the collimator jaws or with over-modulating of the plan.

Building Information Modelling is the latest phase of a revolutionary process that over the last thirty years has profoundly transformed the world of design in the construction sector in all its different disciplines: architecture and engineering design, mechanical/electrical/plumbing engineering, operation and maintenance, cost and safety, etc. From 2D and 3D assisted design to parametric design, the innovation has led to a profound change of perspective as far as the way of conceiving the work in all its phases is concerned, from concept to execution and consequently to management. BIM methodological approach, based on sharing and interoperability, opens up a potential range of future applications, although nowadays it is mainly used in the MEP (mechanical, electrical and plumbing engineering) sector. One of the most interesting applications can be developed in urban and infrastructural design (Infra-BIM), where the processes and the controls implemented by BIM can be managed effectively and at a higher efficiency level. The term Infra-BIM is used in reference to the adoption of the BIM methodology in the infrastructure sector. An area that by itself calls for a strong disciplinary interconnection with Geographic Information Systems (GIS) and involves many aspects, from the analysis of the area analysed to the relations and interferences with other infrastructures. A multidisciplinary approach that, consequently, requires the correct implementation of the BIM methodology reached by checking the coherence and quality of the information input in the models. The paper focuses on the phase of BIM Validation viewed as a support for a proper work-flow: it not only allows to analyse the whole set of information associated with a parametric object but also how the entire model matches the specific design requirements.

The term Infra-BIM is used in reference to the adoption of the BIM methodology in the infrastructure sector.

The causes of accidents in the crossings are many and cannot be alone traced back to the "irresponsible" action of the pedestrian, but should instead be sought above all in the failure to plan urban pedestrian itineraries, in the disorderly organization of the urban functions, in poor vehicle traffic planning and in the poor quality of road infrastructure design.The presence of pedestrian areas allows greater safety during the crossing, especially for users with reduced mobility or for the elderly as they provide a protected area where they can stop especially if the crossing is wide and the pedestrian traffic light cycle has a phase of reduced green.Generally the area bounded by the perimeter of the island is forbidden to the circulation of all vehicles, but can be used by pedestrians as a refuge for crossing the roadway, when the island is affected by a pedestrian crossing.The present work shows a comparison of traffic and safety scenarios hypothesizing the addition of a pedestrian island in an urban area of the city of Rijeka characterized by a very wide pedestrian crossing and by large pedestrian and vehicular flows. The traffic level of service level (LOS) and the surrogate safety parameters with and without the pedestrian area were evaluated through microsimulation of traffic.

The purpose of this study is to solve the problem of determining the status of an ATM to increase its resiliency, which will reduce the reputational and financial losses of banking structures. The tools for the goal achieving were machine learning methods such as gradient boosting model (on the example of Russian Sberbank ATM data). The study showed good enough accuracy in the problem of binary classification of the status of ATM dispensers, and also revealed the importance of time characteristics of the occurrence of errors and transactions. The methodology has practical value; it is possible to use it outside the banking sector due to the flexibility of the chosen model.The purpose of this study is to solve the problem of determining the status of an ATM to increase its resiliency, which will reduce the reputational and financial losses of banking structures.
