Under horizontal loadings, such as seismic actions, buckling phenomena can strongly affect the bearing capacity of masonry walls to gravity loads. Indeed, due to the low tensile strength of the mortar, when vertically loaded masonry members are subjected to bending moments induced by load eccentricity, out-of-plane collapse mechanisms often prevail
on compressive vertical crushing. This work presents a two-dimensional micromechanical approach relying

A taken-for-granted assumption within the Italian foreign affairs community argues that the relationship between
Rome and Moscow follows a generally cooperative attitude, fostered by strong cultural, economic and political
ties. This narrative misses a significant part of the tale, which is at odds with the idea that the good relations with
Russia are a ‘constant feature’ of Italy’s foreign policy. Indeed, competitive interaction has frequently emerged,

In this paper we consider a semilinear elliptic equation with a strong singularity at $u=0$, namely
\begin{equation*}
\begin{cases}
\dys u\geq 0 & \mbox{in } \Omega,\\
\displaystyle - div \,A(x) D u = F(x,u)& \mbox{in} \; \Omega,\\
u = 0 & \mbox{on} \; \partial \Omega,\\
\end{cases}
\end{equation*}
with $F(x,s)$ a Carath\'eodory function such that
$$
0\leq F(x,s)\leq \frac{h(x)}{\Gamma(s)}\,\,\mbox{ a.e. } x\in\Omega,\, \forall s>0,

OBJECTIVE: We examined patterns of change and stability in the whole set of ten Schwartz values over two years during early adolescence. METHOD: Participants completed the Portrait Values Questionnaire repeatedly throughout the junior high school years. The study involved six waves of data and a total of 382 respondents aged 10 years at the first measurement occasion (43% female). We investigated multiple types of stability in the values: mean-level, rank-order, and ipsative stability. RESULTS: At the mean-level, self-enhancement and openness to change values increased in importance.

We examine the structural overlap of the Behavioral Inhibition System (BIS) and the Behavioral Approach System (BAS) with Stability and Plasticity, the two higher-order factors encompassing the Big Five. Carver and White’s BIS/BAS and the Big Five Inventory were administered to a sample of 330 adults, serving both as targets and informants. Self- and other-ratings were modeled by using the Correlated Trait-Correlated Method model.

Natural esters (triglycerides) possess desirable attributes such as the higher fire points and better environmental compatibility relative to petroleum-derived insulating mineral oil, as a result, the use of such natural esters is on the rise as insulating and heat transfer fluids in electrical devices such as transformers. However, natural esters differ significantly in chemical composition from mineral oils and are more prone to oxidation than mineral oils.

Introduction to Zoom-out n. 61 on "Procedural Law of International Courts and Tribunals: Between Change and Stability".
International procedural law has drawn increasing attention in the last years. This Zoom-out is dedicated to an aspect of international pro- cedural law that nonetheless is generally overlooked, that is, the very characteristics of international procedural rules when conceived of as sources of international law. Basically, two main sets of questions have been submitted to the authors:

The role of thermodynamics in assessing the intrinsic instability of the CH3NH3PbX3 perovskites (X = Cl,Br,I) is outlined on the basis of the available experimental information. Possible decomposition/degradation pathways driven by the inherent instability of the material are considered. The decomposition to precursors CH3NH3X(s) and PbX2(s) is first analysed, pointing out the importance of both the enthalpic and the entropic factor, the latter playing a stabilizing role making the stability higher than often asserted.
