Abstract	Aim: The integrity of primary dentition is essential in the development of the jaws and permanent occlusion. The consequences of a premature loss of primary molars are: space loss, crowding, risk of impaction of the permanent teeth, ectopic eruption, anomalous inclination of the teeth adjacent to the loss molar, reduction of arch length. The mesial displacement of the posterior permanent teeth during eruption can cause a loss of space, which can be regained with orthodontic appliances. Therefore, a careful diagnosis is of great importance to be able to decide what appliance is indicated to recover from this situation. Molar distalisation consists in displacing permanent molars distally, allowing them to reach class I relationship and to recover the correct space for the second bicuspids when the second deciduous molar has been lost early. Methods: The aim of this study is to carry out a narrative literature review regarding the different appliances and their effectiveness in regaining space after premature loss of the upper primary molars. Conclusion: The paediatric dentist should be aware of the advantages and disadvantages related to each device and select the most appropriate distalisation appliance based on an individual plan of diagnosis and a careful treatment. The distalisation of the upper molar must be adequately stabilised and so it is important to consider also some retainers such as Nance's appliance, the Palatal Plate, the extraoral traction, the utility arch, or II Class elastic bands.

Abstract	We present the first real attempt to directly and continuously measure GEM through a Lumex RA-915 M, designed for real-time detection of mercury vapor, mounted on an UAV (Unmanned Aerial Vehicle, namely a heavy-lift octocopter), inside and outside the former Hg-mining area of Abbadia San Salvatore (Mt. Amiata, Italy), known as a GEM source. We tested the effectiveness of the UAV-Lumex combination at different heights in selected sites pertaining to both mining facilities and surrounding urban zones, shedding light on the GEM spatial distribution and concentration variability. The Lumex great sensitivity and the octocopter optimal versatility and maneuverability, both horizontally and vertically, allowed to depict the GEM distribution in the atmosphere up to 60 m above the ground. The acquisition system was further optimized by: i) synchronizing Lumex and UAV GPS data by means of a stand-alone GPS that was previously synchronized with Lumex; ii) using a vertical sampling tube (1.20 m high) connected to the Lumex inlet to overcome the rotors strong airflows and turbulence that would have affected GEM measurements; iii) supplying the octocopter with batteries for power supply to avoid the release of exhaust gases; iv) taking the advantage of the UAV ability to land in small spaces and stop at selected altitudes. The resulting dot-map graphical representations, providing a realistic 3D picture of GEM vertical profiling during the flights in near real-time, were useful to verify whether the guideline concentrations indicated by competent authorities were exceeded. The results showed that the GEM concentrations in the urban area, located a few hundred meters from the mining structures, and close to already reclaimed areas remained at relatively low values. Contrarily, GEM contents showed significant variations and the highest concentrations above the facilities containing the old furnaces, where increasing GEM concentrations were recorded at decreasing heights or downwind.

Abstract	The replacement of synthetic and petroleum-based ingredients with greener alternatives of natural origin is an imperative issue in rubber technology for the tire industry. In this study, a glycerin-esterified maleated rosin resin, derived from natural resources, is examined as a potential tackifier in styrene-butadiene rubber (SBR) formulations. A comparison is made with two synthetic resins commonly used as tackifiers in tire manufacturing: a petroleum-derived aromatic resin and a phenolic resin. Specifically, this research investigates how these resins affect the structure, dynamics, and curing characteristics of SBR compounds, which are strictly related to the mechanical and technological properties of the final products. Moving die rheometer and equilibrium swelling experiments are employed to analyze vulcanization kinetics and crosslink density, which are differently influenced by the different resins. Information on the polymer-resin compatibility is gained by differential scanning calorimetry and dynamo-mechanical analysis, while solid-state NMR methods offer insights into the structure and dynamics of both cured and uncured SBR compounds at the molecular level. Overall, our analysis shows that the resin of vegetal origin has a comparable impact on the SBR compound to that observed for the synthetic resins and could be further tested for industrial applications.

Abstract	Aim: The aim of this study consists in comparing the two-step treatment with that performed in a single-step in adolescent patients. Materials and methods: Study design: This paper is a critical review of the literature with a systematic approach. The search for scientific articles was performed on the US National Library of Medicine database using the PubMed service. Keywords set: "Early treatment Class II OR 1-phase orthodontics OR orthodontic timing Class II". From the initial screening 20 articles were selected of which the full text has been researched and evaluated. Results: The selected articles were reviewed and evaluated by two independent operators, who both excluded two papers. Ultimately 13 articles were selected that refer to four major working groups, respectively from Manchester, North Carolina, Florida and Queen Mary University of London. Conclusion: We can assume that both the one- and two-step treatment are effective in correcting Class II malocclusion, with no significant difference of outcome, except for the incidence of incisor trauma, which was significantly lower for the early treatment group.

Abstract	Herding has often been blamed as one of the possible causes of market instabilities, ultimately yielding to bubbles and crushes. On the other hand, researchers hypothesized that financial systems may benefit from the so-called wisdom of the crowd. To solve this apparent dichotomy, we leverage a novel financial market model, where the agents form their expectations by combining their individual return estimation with the expectations of their neighbors. By establishing a link between herding, sociality, and market instabilities, we point out that the emergence of collective decisions in the market is not necessarily detrimental. Indeed, when all the agents tend to conform their expectations to those of one or few leaders, herding might dramatically reduce market efficiency. However, when each agent accounts for a plurality of opinions, thus following the wisdom of the crowd, market dynamics become efficient. Following these observations, we propose two alternative control strategies to reduce market instability and enhance its efficiency.

Abstract	Purpose of review: To describe and popularize the transmanubrial osteomuscular-sparing approach (TOSA) outside its original thoracic surgical field of application, based on the consideration that it could be of interest for the management of a number of head and neck cases in both elective and emergent scenarios. Recent findings: The main advantages of TOSA compared with transclavicular techniques are its superb exposure of anatomic structures located at the level of the cervicothoracic junction, and superior postoperative aesthetic and functional outcomes. Recently, a number of studies have described the association of TOSA with other minimally invasive approaches, such as video-assisted thoracoscopic surgery and robotic hybrid approaches, with the aim of avoiding association of the transmanubrial route with anterior/posterior thoracotomies, or more extended surgeries, such as the trapdoor or hemiclamshell procedures. Summary: TOSA, even though originally conceived to reduce the morbidity ensuing from classic transclavicular approaches for management of Pancoast tumors, may well play an important role in a number of head and neck surgical conditions, including those related to mediastinal goiter and thyroid cancer, management of stenosis and lesions of the thoracic trachea and esophagus, treatment of the junction between innominate, internal jugular, and subclavian veins, epiaortic arteries, thoracic duct, brachial plexus, and low sympathetic chain. Whenever comprehensive control of vascular and nonvascular structures of the upper mediastinal inlet is required, TOSA should be planned and performed by combining the expertise of cooperating professionals.
