Critical Pressure of Intramural Delamination in Aortic Dissection

Computational models of aortic dissection can provide novel insights into possible mechanisms by which this potentially lethal condition develops and propagates. We present results from a phase-field based finite element simulation of a classical experiment that had not previously been understood. Initial simulations agreed qualitatively and quantitatively with the experimental findings, but because of the complexity of the boundary value problem it was still difficult to build intuition. Hence, simplified analytical models were extended to gain further insight. Together, the simplified models and phase-field simulations revealed a power-law-based relation between the pressure required to initiate an intramural tear and key geometric and mechanical factors - area of the initial insult, stiffness of the wall, and characteristic energy of tearing. The degree of axial stretch and luminal pressure similarly influenced the value of the tearing pressure, which was ~70 kPa for a healthy aorta having a sub-millimeter-sized initial insult but even lower for larger tear sizes. Finally, the simulations showed that the direction a tear propagates can be altered by focal regions of weakening or strengthening, which can drive the tear towards the lumen (re-entry) or adventitia (rupture). Additional data are needed, however, on aortas having different predisposing disease conditions.

S. Milgram’s experiment through the lens of historical psychology

The article presents a look at the results of the classical experiment of S. Milgram from the point of view of the theories of B. Porshnev and D. Jaynes. A review of the provisions of both theories that are relevant to the analysis of the experiment of S. Milgram is given. A comparative analysis was carried out. It is shown that both theories postulate the existence in human history of a period when our ancestors were guided in their behavior not by their own motives, goals and objectives, but by other people’s speech commands — either given by real leaders (B. Porshnev), or their “doubles” — voice-hallucinations (D. Jaynes). If we agree with the authors of these theories, the unquestioning obedience to “authority”, demonstrated by the majority of subjects in the experiment of S. Milgram, is in a certain sense a recurrence of those psychological mechanisms and behaviors that existed in a person in that historical era of total suggestion (according to B. Porshnev) or “bicameral mind” (according to D. Jane).

DEPENDENCE OF AFFIRMATION EFFECTS ON THE EMOTIONAL COLORING OF THE OBJECT

The current paper features an attempt at a new interpretation of the affirmation phenomena introduced by D. N. Uznadze. The author considers the process of affirmation forming as the implementation of measurement actions. The idea is that measurement actions, in addition to their direct function, also structure the background perceptual space (which is believed to shape the cognitive medium of perception images). Distortions of the measurement procedure, in one way or another, correlate with different forms of structuring the background perceptual space and with its increasing role in emotional coloring. The article describes an experiment in which the objects were not only perceived and evaluated, but also influenced the accuracy of the perception of objects, since they "control" the forms of the structuring of the background space and give it an emotional coloring. The experiment was carried out according to a procedure similar to the classical experiment conducted by D. N. Uznadze. The experiment featured an illusion of affirmation formation through the multiple presentation of circles of different diameters. We used circles of the same size, but with different versions of images inside: an emotionally colored image ("smileys"), ordered emotional ("triangles"), disordered emotionless ("chaotic points"). As a result, the emotionally colored image inside the circles caused an increase in the number of errors in the comparison of the circles, and the ordered, non-emotional image increased the accuracy of perception.

Book Review of „Noua eră a vechilor media. O analiză experimentală a efectelor produse de cadrajele media” [The New Era of Old Media. An Experimental Analysis of Media Framing Effects] by Raluca Buturoiu, București: Comunicare.ro, 2016, 272 p.

<p>Media studies focus increasingly on new media, while traditional media effects start to be overlooked although these effects are by no means minimal. `<em>The new era of old media. An Experimental Analysis of media framing effects` </em>draws attention to the effects of old media that continue to influence the opinions and attitudes of young people. Media framing determines how citizens make sense of the information they are provided with, the framing effects theory being the starting point for the classical experiment developed by the author to test the magnitude and significance of traditional Romanian media effects nowadays.</p>

Electronic structure and time-dependent description of rotational predissociation of LiH

The adiabatic potential energy curves of the LiH molecule have been calculated. By solving the TDSE, the classical experiment of Velasco on dissociation in the 1Π state has been explained for the first time in detail.

CLASSICAL EXPERIMENT IN CINE MUSIC

Indian films cannot be imagined without music. The hallmark of Indian cinema is its vibrant music. Indian films, whether they are in any language (ie Hindi, Tamil, Bengali, Marathi, Telugu, Kannada or Malayalam), music predominates. Music is their basic element in films made in regional dialects like Bhojpuri, Rajasthani, Bandeli, Chhattisgarhi etc. Most of the films in India are made in Hindi language which are popular all over the world. Hence, we will discuss about Indian films by keeping Hindi films at the center. संगीत के बिना भारतीय फिल्मों की कल्पना भी नहीं की जा सकती। भारतीय सिनेमा की पहचान उसका सषक्त संगीत ही है। भारतीय फिल्में चाहे वे किसी भी भाषा (अर्थात् हिन्दी, तमिल, बंगाली, मराठी, तेलुगु, कन्नड़ या मलयालम) की हों, संगीत उनमें प्रमुख होता है। क्षेत्रीय बोलियों जैसे भोजपुरी, राजस्थानी, बंुदेली, छत्तीसगढ़ी आदि में बनने वाली फिल्मों में तो संगीत ही उनका मूल तत्व होता है। भारत में सर्वाधिक फिल्में हिन्दी भाषा में बनती हैं जो विश्व भर में लोकप्रिय होती हैं। अतः आगे हम भारतीय फिल्मों की चर्चा हिन्दी फिल्मों को केन्द्र में रखकर ही करेंगे।

CLASSICAL EXPERIMENT IN CINE MUSIC

From the beginning of the creation man has wandered in search of happiness. Its imagination has been keeping pace with this creation and this imagination has been trying to materialize the artistic tendency. To provide stability to the beauty of nature, fine arts were born and music is considered to be the highest place in the fine arts. In the words of Dr. Nisha Rawat ji, music is the moral law of the world, it fills the human mind with colorful colors in new colors and emotions. Music brings joy to the forecourt of despair and enlivens life and enthusiasm in every substance of the world. Nowadays, from morning to evening and sometimes 24 hours and continuous music echoes in our ears in many forms. In any place or any work, music continues to spread like the haze of the sky. सृष्टि के आरम्भ से मानव आनंद की खोज में भटकता रहा है। इसकी कल्पना, इस सृष्टि के साथ तालमेल स्थापित करती रही है और यह कल्पना ही, कलात्मक प्रवृत्ति को मूर्त रूप देने की कोशिश करती रही है। प्रकृति के सौन्दर्य को स्थायित्व प्रदान करते के लिए ललित कलाओं का जन्म हुआ और ललित कलाओं में सबसे ऊँचा स्थान माना गया है, संगीत का। डाॅ0 निशा रावत जी के शब्दों में संगीत विश्व का नैतिक विधान है,यह मानव मस्तिष्क में नवीन रंग और भावनाओं मंे रंगीन उडान भरता है। संगीत निराशा के प्रांगण में आनन्द का प्रपात प्रवाहित करता है तथा विश्व के प्रत्येक पदार्थ मे जीवन और उत्साह को मुखरित करता है। आजकल सुबह से शाम तक व कभी-कभी चैबीस घंटे व अनवरत संगीत की गूँज हमारे कानों में अनेेक रूपों में पडती रहती है। कोई भी स्थान हो या कोई भी कार्य हो सब जगह आकाश की धुन्ध की भाँति संगीत का प्रसार होता रहता है।
