The conservation of a 2nd-century AD shipwreck represents a challenge in many ways: the amount of material, different ones such as waterlogged wood, iron, lead, textiles, pitch, among others. A global project has to be planned, meaning that scale adaptations had to be thought of taking into account the exceptional size and diversity matters. On top of it, a common thread with pyrite has to be taken into account to avoid acidification by little footsteps at each conservation care stage. To do this, a complete dismantling has occurred, allowing the removal of 26 meters of waterproofing material which happened to be pitched textiles. To explore the data embedded inside, a new unfolding protocol had to be elaborated; that respected their fragility. New issues arose from this work, allowing to link the textiles to the barge, and also opened new exploration fields of an exceptional set of roman textiles.

Purpose In the 10 years since the International Cluttering Association (ICA) was created, this organization has been growing in the scope of its initiatives, and in the variety of resources it makes available for people with cluttering (PWC). However, the awareness of this disorder and of the methods for its intervention remain limited in countries around the world. A celebration of the multinational and multicultural engagements of the ICA's Committee of the International Representatives is a common thread running through all the articles in this forum. The first article is a joint effort among international representatives from five continents and 15 countries, exploring various themes related to cluttering, such as awareness, research, professional preparation, intervention, and self-help groups. The second article, by Elizabeth Gosselin and David Ward, investigates attention performance in PWC. In the third article, Yvonne van Zaalen and Isabella Reichel explain how audiovisual feedback training can improve the monitoring skills of PWC, with both quantitative and qualitative benefits in cognitive, emotional, and social domains of communication. In the final article, Hilda Sønsterud examines whether the working alliance between the client and clinician may predict a successful cluttering therapy outcome. Conclusions Authors of this forum exchanged their expertise, creativity, and passion with the goal of solving the mystery of the disconcerting cluttering disorder with the hope that all PWC around the globe will have access to the most effective evidence-based treatments leading to blissful and successful communication.

This essay explores theatre's power to take an audience beyond the veil of civilization into an encounter with the human as monstrous. Through the mythology and theatre of the Greeks, through Shakespeare, and into contemporary plays and productions by Bond, Albee, Osborne, and Bejart, the figure of the ‘overreacher’ emerges as a common thread. In extraordinary performances in his own Talbot’s Box and Double Cross, Kilroy traces the role of the actor in exteriorizing the disturbing paradox of the monster as violation and as beauty.

The property of brittleness for polymers and polymer-based materials (PBMs) is an important factor in determining the potential uses of a material. Brittleness of polymers may also impact the ease and modes of polymer processing, thereby affecting economy of production. Brittleness of PBMs can be correlated with certain other properties and features of polymers; to name a few, connections to free volume, impact strength, and scratch recovery have been explored. A common thread among all such properties is their relationship to chemical composition and morphology. Through a survey of existing literature on polymer brittleness specifically combined with relevant reports that connect additional materials and properties to that of brittleness, it is possible to identify chemical features of PBMs that are connected with observable brittle behavior. Relations so identified between chemical composition and structure of PBMs and brittleness are described herein, advancing knowledge and improving the capacity to design new and to choose among existing polymers in order to obtain materials with particular property profiles.

Hiv 1

AIDS is a globalized infectious disease. In 2014, UNAIDS launched a global project of “90-90-90” to end the HIV epidemic by 2030. The second and third 90 require 90% of HIV-1 infected individuals receiving antiretroviral therapy (ART) and durable virological suppression. However, wide use of ART will greatly increase the emergence and spreading of HIV drug resistance and current HIV drug resistance test (DRT) assays in China are seriously lagging behind, hindering to achieve virological suppression. Therefore, recommending an appropriate HIV DRT method is critical for HIV routine surveillance and prevention in China. In this review, we summarized the current existing HIV drug resistance genotypic testing methods around the world and discussed the advantages and disadvantages of these methods.

This article is organized around logicism's answers to the following questions: What is the basis for our knowledge of the infinity of the numbers? How is arithmetic applicable to reality? Why is reasoning by induction justified? Although there are, as is seen in this article, important differences, the common thread that runs through all three of the authors discussed in this article their opposition to the Kantian thesis that reflection on reasoning with mere concepts (i.e., without attention to intuitions formed a priori) can never succeed in providing satisfactory answers to these three questions. This description of the core of the view differs from more usual formulations which represent the opposition to Kant as an opposition to the contention that mathematics in general, and arithmetic in particular, are synthetic a priori rather than analytic.

Abstract The classical Aronszajn–Donoghue theorem states that for a rank-one perturbation of a self-adjoint operator (by a cyclic vector) the singular parts of the spectral measures of the original and perturbed operators are mutually singular. As simple direct sum type examples show, this result does not hold for finite rank perturbations. However, the set of exceptional perturbations is pretty small. Namely, for a family of rank $d$ perturbations $A_{\boldsymbol{\alpha }}:= A + {\textbf{B}} {\boldsymbol{\alpha }} {\textbf{B}}^*$, ${\textbf{B}}:{\mathbb C}^d\to{{\mathcal{H}}}$, with ${\operatorname{Ran}}{\textbf{B}}$ being cyclic for $A$, parametrized by $d\times d$ Hermitian matrices ${\boldsymbol{\alpha }}$, the singular parts of the spectral measures of $A$ and $A_{\boldsymbol{\alpha }}$ are mutually singular for all ${\boldsymbol{\alpha }}$ except for a small exceptional set $E$. It was shown earlier by the 1st two authors, see [4], that $E$ is a subset of measure zero of the space $\textbf{H}(d)$ of $d\times d$ Hermitian matrices. In this paper, we show that the set $E$ has small Hausdorff dimension, $\dim E \le \dim \textbf{H}(d)-1 = d^2-1$.

AbstractThe following work features elements to ponder and an in-depth explanation taken on the Anca Vasiliu’s study about the possibilities and ways of thinking of God by a rational entity, such as the human being. This is an ever relevant topic that, however, takes place in relation to Platonic authors and texts, especially in Late Antiquity. The common thread is that the human being is a God’s creature who resembles him and who is image of. Nevertheless, this also applies within the Christian Trinity according to which, not without problems, the Son is the image of the Father. Lastly, also the relationship of the Spirit with the Father and the Son, always within the Trinity, can be considered as a relationship of similarity, but again not without critical issues between the similarity of attributes, on the one hand, and the identity of nature, on the other.

Water is the common thread and attraction factor of the tourism facilities called “spas”, which are part of health and beauty services. Spa use is currently experiencing a boom that reflects changes in populations, such as an increase in economic wellbeing and a desire to reunite with nature. This research’s objectives were to understand spa tourism’s structural and operational dimensions and to assess this sector’s current situation by using the Delphi method with a panel of 22 experts. The results show that these experts believe that, in Andalusia, spas energize the area as a tourism destination through their natural resources and conservation of key elements. However, spa development policies are scarce, including a lack of autonomous community laws regarding these facilities.
