The path of the search has been long and complex but rich in cultural, economic, religious, and human aspects. The relations between these two ports, Malta and Trieste, full of a painful and difficult but also glorious and fair history, have had their ups and downs as a theater, not so much land as the sea, and in this case the Mediterranean. This area has led to a similar vision of the historical aspects of the various dominations, and has a significant influence on the habits, customs and life of the people of Malta and Trieste. Their particularly complex history has unfolded with ups and downs, contrasting with other difficult times more happier and constructive as it has always, however, in the history of man. The purpose of this article is to analyze and arrange manifestly the history of commercial and maritime interchanges between Malta and Trieste, not achieved in Korea until now. This material has high scientific value gathering sufficient data for this article.

Oligopeptidase B (OpdB) is a serine peptidase widespread among bacteria and protozoa that has emerged as a virulence factor despite its function has not yet been precisely established. By using an OpdB-overexpressing Escherichia coli strain, we found that the overexpressed peptidase makes the bacterial cells specifically less susceptible to several proline-rich antimicrobial peptides known to penetrate into the bacterial cytosol, and that its level of activity directly correlates with the degree of resistance. We established that E. coli OpdB can efficiently hydrolyze in vitro cationic antimicrobial peptides up to 30 residues in length, even though they contained several prolines, shortening them to inactive fragments. Two consecutive basic residues are a preferred cleavage site for the peptidase. In the case of a single basic residue, there is no cleavage if proline residues are present in the $P_1$ and $P_2$ positions. These results also indicate that cytosolic peptidases may cause resistance to antimicrobial peptides that have an intracellular mechanism of action, such as the proline-rich peptides, and may contribute to define the substrate specificity of the E. coli OpdB.

Per discuteretrattare la problematica concernente un significato intimamente legato a Istria(ora è ilsuolo sloveno ) e a Trieste(ora è il suolo italinao) - quello di ≪frontiera≫, assieme alla ≪cultura e letteratura di frontiera≫ - si dovrebbe fare un'incursione nella storia. In un'altra relazione, analizzando il particolare inserimento di queste città adriatiche nella dinamica fluttuante del rapporto fra centro e provincia nello spazio mitteleuropeo, abbiamo accennato al fatto che, alla fine della prima guerra mondiale, Trieste diventa un centro periferico, situato all'estremo confine orientale d'Italia, in altre parole, una vera e propria ≪città di frontiera≫. E Istria è uno stato dell'Europa centrale confinante ad ovest con l'Italia, percui In Slovenia c'è una comunità autoctona italiana nella parte istriana. Vera "città invisibil" nella topografia del Novecento, Trieste ed Istria ebbero in sorte, negli anni che precedettero la Grande Guerra e la sua (per certi aspetti esizale) annessione all'Italia, un manipolo invidiabile di cantori. Il mito storiografico di una " letteratura triestina" sembrano dovuti, fatte salve le necessarie e risapute considerazioni cronlogiche e ambientali, a una straordinaria intuizione collettva. Più sospettiamo in loro la lucida consapevoleza dell'enorme potenzialità spirituale che scaturisce dalle condizioni materiali: dal determinato assetto di un paesaggio umano, razzi, momenti, e mile compresi. È stato forse proprio Pietro Antonio Gambini a spiegare meglio di chiunque altro questa originalissima configurazione dell'intelligenza e della fantasia in quella Rosa rossa. Il saggio esamina il rapporto di Antonio Gambini con la 'letteratura treistina' e con la movimentata attività letteraria di ≪Solaria≫. Si focalizza l'attenzione con il primo romanzo di Gambini La rosa rossa che rappresenta un omaggio al mondo istriano della sua adolescenza alla base della l'assimilazione di un ambiente cosmopolita a una parlata e a una cultura, nella fattispecie la parlata veneta dei commerci e la cultura.

A numerical model for masonry is proposed by following an internal variable approach originally developed in the field of elastic-plastic analysis. The general features of the theoretical framework are discussed by focussing on finite element models applicable to incremental elastic-plastic problems. An extremum property is derived and its implications in terms of convergence for convenient algorithms are briefly discussed, by including the case of softening materials and damage effects. Next, a numerical model is presented, which is suitable for masonry, can be developed according to the same internal variable formulation and enjoys similar properties. Some numerical results are presented and compared with the response of a masonry shear wall subjected to pseudodynamic tests.

The aim of the paper is to present some results about the influence of rheological phenomena on steel-concrete composite beams. Both the cases of slab with normal and high performance concrete for one and two-span beams are analysed. A new finite element model that allows taking into account creep, shrinkage and cracking in tensile zones for concrete, along with non-linear behaviour of connection, steel beam and reinforcement, has been used. The main parameters that affect the response of the composite beam under the service load are highlighted. The influence of shrinkage on the slip over the supports is analysed, together with the cracking along the beam. At last, by performing a collapse analysis after a long-term analysis, the influence of rheological phenomena on the ductility demand of connection and reinforcement is analysed.

The paper focuses on the dynamic response of a blast-invested glass-steel curtain wall supported by single-way pretensioned cables. In order to mitigate the critical components of the façade from severe structural damage, an innovative system able to absorb and dissipate part of the blast-induced stresses in the critical façade components is proposed. To improve the blast reliability of the studied glazing system, specifically, rigid-plastic and elastoplastic devices are introduced at the base and at the top of the vertical bearing cables. Several combinations and mechanical calibrations of these devices are numerically investigated and the most structurally and economically advantageous solution is identified. In conclusion, a simple analytical formulation totally derived from energetic considerations is also suggested for a preliminary estimation of the maximum dynamic effects in single-way cable-supported façades subjected to high-level blast loads.

This paper analyses the response of rigid and semi-rigid steel-concrete composite joints under monotonic loading. The influence of some important parameters, such as the presence of column web stiffening and the mechanical properties of component materials, is investigated by using a three-dimensional finite element modelling based on the Abaqus code. Numerical and experimental responses of different types of composite joints are also compared with the analytical results obtained using the component approach proposed by Eurocode 4. The results obtained with this approach generally fit well with the numerical and experimental values in terms of strength. Conversely, some significant limits arise when evaluating initial stiffness and non-linear behaviour of the composite joint.

The paper concerns the modelling of rigid and semi-rigid steel-concrete composite joints under monotonic loading through use of the Abaqus program, a widespread finite element code. By comparing numerical and experimental results obtained on cruciform tests, it is shown that the proposed modelling allows a good fit of the global joint response in terms of moment-rotation law. Even the local response in terms of stresses and strains is adequately predicted. Hence, this numerical approach may represent a useful tool for attaining a better understanding of experimental results. It may also be used to perform parametric analyses and to calibrate simplified mechanical models for practical applications.

In this work the possibility of obtaining a rectilinear motion of bodies partially or totally submerged without using propellers is evaluated. The system propulsion is based on a pair of counter rotating masses that generate the thrust. The fluid-body system has been schematized in order to carry out a very simple model. Using this model an evaluation of the body motion along a longitudinal direction was performed. The motion equations of the system were written and integrated. The external forces applied to the body depend on its velocity in relation to the water. These forces were obtained by fluid dynamic simulations. Regarding the mechanical configuration suggested, the results obtained show that a certain displacement of the body along a fixed direction is obtainable.

The heterologous expression of sodN gene from Streptomyces seoulensis in Streptomyces lividans together with the gel filtration and sedimentation equilibrim data indicated that the quaternary structure of NiSOD is homohexamer, which is novel among SODs, not the previously reported homotetramer. The EPR spectrum of $^{61}$ Ni (I = 3/2) substituted NiSOD showed a clear resolved hyperfine structure at g=2.016, unambiguously identifying that the EPR signal from NiSOD is due to Ni.(omitted)
