A note on drastic product logic

The drastic product $*_D$ is known to be the smallest $t$-norm, since $x *_D y = 0$ whenever $x, y < 1$. This $t$-norm is not left-continuous, and hence it does not admit a residuum. So, there are no drastic product $t$-norm based many-valued logics, in the sense of [EG01]. However, if we renounce standard completeness, we can study the logic whose semantics is provided by those MTL chains whose monoidal operation is the drastic product. This logic is called ${\rm S}_{3}{\rm MTL}$ in [NOG06]. In this note we justify the study of this logic, which we rechristen DP (for drastic product), by means of some interesting properties relating DP and its algebraic semantics to a weakened law of excluded middle, to the $\Delta$ projection operator and to discriminator varieties. We shall show that the category of finite DP-algebras is dually equivalent to a category whose objects are multisets of finite chains. This duality allows us to classify all axiomatic extensions of DP, and to compute the free finitely generated DP-algebras.Comment: 11 pages, 3 figure

Prevailing Arguments and Types of Conclusions of Parent\u2013Child Argumentation

This chapter examines the types of arguments used most often by parents and children and the different types of conclusions of their argumentative discussions. The conceptual tool adopted for the analysis is based on the integration of the pragma-dialectical ideal model of a critical discussion (van Eemeren &amp; Grootendorst, 2004) with the Argumentum Model of Topics (Rigotti &amp; Greco Morasso, 2019). The integration of these two tools of analysis permits to reconstruct the inferential configuration of the arguments used by parents and children and to identify the types of conclusions of their argumentative discussions. Exemplary argumentative sequences that bring to light the results obtained through the qualitative analysis of a larger corpus of argumentative discussions between parents and children are presented and discussed

MORPHOLOGICAL AND BIOMECHANICAL CORRELATION IN THE TENNIS ELBOW

With the definition of 'Tennis Elbow' are rubricated a series of pathologies which recognize a common origin in a damage on a level of the myotendon jointing apparatus. A decodification in biochemical molecular key of the jointing apparatus consents to identify a series of microstructures which develop specific functions of a connection between the motory unity and the tendon system. These formations ty ambient such as the one assured by proteoglicanic matrix in which perform the nervous formations wich are appointed to the peripheric control of the rnyotendon jointing. The morphological research led on a level of the myotendon jointings in normal conditions and in the course of insertional pathologia, has displayed howat an insertional level, it takes place deep structural changes characterized by progressive loss of the visco-elasticity . These dates have been put in relation to study of the elbow and wrist joints, in normal conditions and in course of 'tennis elbow'. In particular it has been inquired, in isokinetic, the relation of force of / the 'motor muscles' which control the motory unities of the elbow and wrist joints. In has been observed significative alteration of case control in the peak torque ratio (%) of the an d flex muscles of the wrist (80 vs 40) in the relation of pronators/supinators (138 vs 88). The results of this study suggest how at the base of “tennis elbow' there are biological and biomechanical conditions which determine the arising of pathologia, they condition the evolution and constitute the potential 'target' of the therapy

dynamic simulation of the temperature inlet turbine control system for an unfired micro gas turbine in a concentrating solar tower

Abstract In this work, the dynamic performance of a mass flow regulation system, in a concentrating solar tower plant, with unfired closed micro gas turbine, during clouds transient will be presented. The adjustment system operates with the heliostats field control system, in order to control the temperature inlet turbine. To choose the best configuration, the performance of three heliostats sizes, for four Solar Multiple, has been evaluated. The design of the solar field was carried out by means of Solar Pilot, while the numerical models have been developed in Matlab/Simulink. The results show that a particular configuration is suitable for this purpose

Introducing Pharmacogenetics and Personalized Medicine via a Weblog

to freshmen pharmacy students’ knowledge base. Methods: Incoming freshmen pharmacy students were invited by email to enroll in a one semester-hour, elective, on-line blog-based course entitled “Personal Genome Evaluation”. The course was offered during the students’ first semester in college. A topic list related to PGt and PM was developed by a group of faculty with topics being presented via the blog once or twice weekly through week 14 of the 15 week semester. A pre-course and post-course survey was sent to the students to compare their knowledge base relative to general information, drug response related to PGt, and PM. Results: Fifty-one freshmen pharmacy students enrolled in the course and completed the pre-course survey and 49 of the 51 students completed the post-course survey. There was an increase in the students’ general, PGt and PM knowledge base as evidenced by a statistically significant higher number of correct responses for 17 of 21 questions on the post-course survey as compared to the pre-course survey. Notably, following the course, students had an increased knowledge base relative to “genetic privacy”, drug dosing based on metabolizer phenotype, and the breadth of PM, among other specific points. Conclusions: The study indicated that introducing PGt and PM via a blog format was feasible, increasing the students’ knowledge of these emerging areas. The blog format is easily transferable and can be adopted by colleges/schools to introduce PGt and PM

Psychology and hereditary angioedema: A systematic review

Background: Hereditary angioedema (HAE) is caused by mutations in the C1 inhibitor (C1-INH) gene Serpin Family G Member 1(SERPING1), which results in either the decreased synthesis of normal C1-INH (C1-INH–HAE type I) or expression of unfunctional C1-INH (C1-INH–HAE type II). In recent studies, emotional stress was reported by patients as the most common trigger factor for C1-INH–HAE attacks. Moreover, patients reported considerable distress over the significant variability and uncertainty with which the disease manifests, in addition to the impact of physical symptoms on their overall quality of life. Objective: We did a systematic review of the literature to shed light on the advancements made in the study of how stress and psychological processes impact C1-INH–HAE. Methods: All of the articles on C1-INH–HAE were analyzed up to December 2019. Both medical data bases and psychological data bases were examined. The keywords (KWs) used for searching the medical and psychological data bases were the following: “hereditary angioedema,” “psychology,” “stress,” “anxiety,” and “depression.” Results: Of a total of 2549 articles on C1-INH–HAE, 113 articles were retrieved from the literature search by using the related KWs. Twenty-one of these articles were retrieved, examined, and classified. Conclusion: Although the literature confirmed that stress may induce various physical diseases, it also warned against making simplistic statements about its incidence that did not take into account the complexity and multicausality of factors that contribute to C1-INH–HAE expression

The Initial Phase of the Argumentative Discussions Between Parents and Children

This chapter examines the initial phase of parent\u2013child argumentative discussions during mealtime. The conceptual tool adopted for the analysis is based on the pragma-dialectical ideal model of a critical discussion (van Eemeren &amp; Grootendorst\u201a 2004). The types of issues leading parents and children to engage in argumentative discussions during mealtime as well as the contribution that parents and children provide to the inception of argumentation are described and discussed. The analysis of the initial phase of parent\u2013child argumentative discussions also considers the role played by the specificity of the parent\u2013child relationship and the distinctive features of the activity of family mealtime for the beginning of an argumentative discussion. Exemplary argumentative sequences that bring to light the results obtained through the qualitative analysis of a larger corpus of argumentative discussions between parents and children are presented and discussed

Conclusions

What is the function of parent–child argumentation? This chapter intends to answer the main research question that has guided the study presented in this volume and open a discussion for future research on this topic. In the first part, the chapter provides a detailed overview of the main findings of the analysis of parent–child argumentative discussions during mealtime. The role played by parents and children in the inception and development of argumentation, and the types of conclusions of their argumentative discussions are described. Subsequently, two educational targets achieved by parents and children through their argumentative interactions are presented and critically discussed. In the last part, new open questions that should guide future investigation to expand our knowledge of the role and function of argumentation between parents and children are proposed

Argumentative schemes and symptomatic, causal, and analogical relations in discursive exchanges between adults and children

This study aims to explore the interplay between parents' arguments, children's types of reaction and topics of disagreement during mealtime conversations. Within a data corpus constituted by 30 video-recorded meals of 10 Swiss and Italian families, a corpus of 132 argumentative discussions was selected for a qualitative analysis. The findings of the pragma-dialectical analysis indicate that both parents and children assume argument schemes related to the object of the disagreement: when the contested standpoints refer to food, arguments are based on a symptomatic relation; when they refer to the behavior of children, parents base their argumentation on a causal and analogy relation. Moreover, the children's type of reaction is typically an expression of further doubts or a mere opposition without providing any argument. The implications concerning the use of argumentative schemes are discussed in terms of possibilities of mutual learning occurring during daily discursive exchanges between parents and children
