Authors: ONAN Berna COŞKUN , ÜNLÜSOY Mert
Published: November 2020

Based on the learning outcomes, values, skills/proficiency and job safety for grades 6, 7 and 8 from the 2017 Visual Arts Course Curriculum (MEB, 2017), outcomes related to three-dimensional work have been associated with care, love, responsibility and inquiry and activities “My Money”, “Abstract Sculpture” and “Talking Emojis” have been planned. They have been completed with visually rich presentations and step by step implementation phases and presented to the subject teachers intended for practices. In the data collection process, the activities were observed by the researcher, audio and video recording made and right after the activities interviews with the students and teachers were made and student work was collected to examine documentation. Data obtained during the data collection process have been analyzed with thematic analysis method and taking into consideration the basic characteristic of multiple case study and the themes obtained have been evaluated with the theme titles; “Connections”, “Internalization” and “Realization”. Among the outcomes of the results of the research are the facts that the bases of skill/proficiency, value and job safety are important at activity planning and that rich presentations and step by step applications can transfer the relevant outcomes of the students into behavior. It is also attention-grabbing that students, who gain the values of respect, love and care for their environment through three-dimensional work, can transfer mathematical, digital, social skills and those related to citizenship to their lives.
Advocaten die vragen, worden door de rechter-commissaris overgeslagen

Advocaten die vragen, worden door de rechter-commissaris overgeslagen

Ter terechtzitting is de regel dat een toegewezen getuige die door de verdediging, à decharge, is opgeroepen en niet eerder is gehoord, door de verdediging wordt ondervraagd. Dat betekent dat zij ter terechtzitting met voorrang boven de andere procespartijen begint ‘haar’ getuige te ondervragen, zij de volgorde van de vragen bepaalt en ook vrij is te kiezen om vragen niet te stellen. Die regel zou ook moeten gelden voor getuigenverhoren bij de rechter-commissaris en wettelijk moeten worden verankerd. In de praktijk vist de verdediging in laatstgenoemde verhoren namelijk nog te vaak achter het net. Advocaten die vragen, worden door de rechter-commissaris overgeslagen.

De ‘Blue Whale Challenge’ en het strafrecht

In deze bijdrage wordt het weerzinwekkende zelfmoordspel de ‘Blue Whale Challenge’ geanalyseerd. De auteur staat in het artikel stil bij de strafbaarstellingen van het aanzetten tot zelfdoding en het bieden van hulp bij zelfdoding, waarna een analyse volgt van de ‘Blue Whale Challenge’ naar Nederlands strafrecht. In deze bijdrage wordt door de auteur gezocht naar andere strafrechtelijke grondslagen om in een vroeg(er) stadium van deze ‘challenge’ in te grijpen. De bijdrage wordt afgesloten met een voorstel voor een nieuwe strafbepaling, mede ingegeven door de positieve verplichtingen van het EVRM.
De opsporings- en vervolgingscompetentie van het Europees Openbaar Ministerie in Nederland

De opsporings- en vervolgingscompetentie van het Europees Openbaar Ministerie in Nederland

Het Europees Openbaar Ministerie gaat ook in Nederland strafbare feiten opsporen en vervolgen die schade toebrengen aan de financiële belangen van de EU. Maar welke feiten precies? Hoe wordt zijn competentie afgebakend van de competentie van de nationale autoriteiten? En hoe wordt verzekerd dat het Europees OM niet alleen formeel, maar ook praktisch in staat is om de opsporingsonderzoeken uit te voeren waarvoor het bevoegd is? Deze bijdrage bespreekt de invoeringswet waarmee het Europees OM in de Nederlandse rechtsorde wordt ingebed, en de competentievragen die daarbij een rol spelen. Sommige punten zijn helder, maar andere leiden slechts tot vraagtekens.

Het voorstel voor een nieuw regelgevend kader voor de gegevensverwerking door samenwerkingsverbanden

Dit artikel gaat nader in op de betekenis van het wetsvoorstel gegevensverwerking door samenwerkingsverbanden. De focus ligt op de vraagstukken die spelen rondom de bescherming van persoonsgegevens. Al geruime tijd bestaan er verschillende samenwerkingsverbanden, zoals de Regionale Informatie- en Expertisecentra (RIEC’s), die beogen bij te dragen aan de ‘integrale’ aanpak van belangrijke maatschappelijke problemen (zoals de ondermijnende criminaliteit). Toch zijn er maar beperkte grondslagen voor de gegevensuitwisseling van dergelijke samenwerkingsverbanden. Dit artikel legt nader uit welke problemen er spelen vanuit privacyrechtelijk oogpunt, waar het relevante nationale en Unierechtelijke toetsingskader uit bestaat, en vervolgens wat de meerwaarde van dit wetsvoorstel is.
Het Europees arrestatiebevel

Het Europees arrestatiebevel – Toch nog mogelijkheden voor een goede verdediging?

Sinds 12 mei 2004 is in Nederland de Overleveringswet van kracht, waarmee de procedure van uitlevering binnen de EU drastisch veranderde. Sindsdien is het Europees aanhoudingsbevel een populair middel voor lidstaten geworden om gezochte verdachten en veroordeelden naar hun grondgebied te krijgen. De rechtsbescherming voor opgeëiste personen is, onder meer door enkele uitspraken van het HvJ EU, allengs minder geworden. De bijstand in overleveringszaken vergt dan ook meer dan alleen het voeren van verweren in overleveringsprocedure zelf. Een proactieve houding, mogelijk zelfs in de fase voorafgaand aan het EAB, kan de opgeëiste persoon een gedwongen reis naar het buitenland besparen.

De Nederlandse implementatie van de Klokkenluidersrichtlijn

Teneinde een minimumbeschermingsniveau te bieden aan personen die in de uitoefening van hun werk in aanraking komen met inbreuken op het Unierecht en hiervan melding maken, is op 7 december 2019 de Europese richtlijn bescherming klokkenluiders in werking getreden. Uiterlijk 17 december 2021 dient deze richtlijn in Nederlandse wetgeving te zijn geïmplementeerd. Om de huidige regelgeving die ziet op dit onderwerp in lijn te brengen met de richtlijn dienen er enkele wijzigingen te worden doorgevoerd. Meer concreet betekent dit dat de regeling voor klokkenluiders, thans neergelegd in de Wet Huis voor klokkenluiders, zal worden aangepast. Eind juli 2020 is het conceptvoorstel van wet, alsmede de conceptmemorie van toelichting gepubliceerd ter consultatie. Op basis van deze stukken worden in deze bijdrage de voorgestelde wijzigingen ten opzichte Wet Huis voor klokkenluiders belicht.
Manipularea prin teatru. Criza-Creatie-Catharsis
Authors:   Editura Universitara, Epingeac Alina
Published: November 2020

Demersul meu este orientat in sensul cercetarii mecanismelor psihologice care stau in spatele comportamentului spectatorului de astazi. Personajul este spectatorul. Receptarea actului artistic s-a modificat; vorbim despre o segregare a publicului, despre „publicuri”, si asistam la o miscare browniana a spectatorilor care populeaza destul de aleatoriu salile de spectacol. Orice incadrare in modele comportamentale sau inregimentare intr-o categorie de public are nevoie de un criteriu perfect sustinut. Alegerea mea se indreapta in zona psihologiei, care poate, prin instrumentele sale specifice, sa dea raspunsul la aparenta lipsa de orientare a spectatorului de azi. Interesul puternic pentru aceasta abordare provine in primul rand dintr-o curiozitate de ordin personal si din nevoia de a-mi explica, din postura de critic de teatru, de ce gustul publicului a devenit atat de pervertit, spectatorul atat de indulgent si care sunt rezultatele imediate ale acestei stari de fapt in raport cu calitatea actului artistic.

Investigating the learning perspective of Searching as Learning, a review of the state of the art
Authors: Gimenez Paulo Jose de Alcantara , Machado Marcelo De Oliveira Costa , Pinelli Cleber Pinelli , Siqueira Sean Wolfgand Matsui
Published: November 2020

Current search engines are not designed to facilitate learning as they do not lead the user to develop more complex skills. Searching as Learning (SAL) emerged as a research area from the intersection of information search and learning technologies in order to advance the study of searching as a learning process. However, we wonder how have the learning theories and approaches been explored in SAL. Through a systematic review of the literature, we identified 65 papers that report SAL solutions. We analyzed them, seeking to answer (i) which learning theories, approaches and methods support the searching as a learning process, and (ii) what metrics, procedures, or treatments were used to measure learning during the searching process. We uncover the learning perspective in the SAL literature, discussing the learning paradigms, the mechanisms influencing the learning process, the search session design for learning and the knowledge gain measurement strategies.

Published: November 2020

O uso da gamificação em ambientes educacionais pode ter efeitos positivos, neutros ou até negativos. Por isso, é essencial avaliar o impacto da gamificação no desempenho dos alunos. Estudos recentes apontam para o uso de análise dirigida aos dados dos estudantes para avaliar a gamificação ao invés de questionários que são pouco escaláveis e podem apresentar vieses que dependem de muitos fatores. Seguindo essa linha, este artigo apresenta um estudo sobre os efeitos de uma plataforma de gamificação estrutural integrada a um juiz on-line com IDE (Integrated Development Enviroment) próprio, para turmas da disciplina de Introdução à Programação de Computadores (IPC). O estudo realizado sobre 9 turmas analisa as correlações entre o tempo que alunos passam no ambiente de programação e na plataforma de gamificação, e seus respectivos desempenhos baseado em suas notas finais. Como resultados, observou-se uma correlação positiva entre o tempo de prática e o desempenho, cuja causalidade mostrou-se provocada pela gamificação.

Die ukrainischen Präsidentschaftswahlen 2019 im historischen Kontext: Paradoxa und Ursachen der Niederlage des Amtsinhabers Petro Poroschenko
Authors:   Umland
Published: November 2020

Erfolgreiche Reformen seit 2014, Wirtschaftswachstum seit 2016 und einige bemerkenswerte außenpolitische Erfolge während Petro Poroschenkos ukrainischer Präsidentschaft 2014-2019 sowie die vollkommene Unerfahrenheit seines Hauptkonkurrenten Wolodymyr Selenskyj stellten wichtige Umstände dar, die dem Amtsinhaber zu einer zweiten Amtszeit als Staatsoberhaupt der Ukraine hätten verhelfen können. Poroschenko jedoch verlor die Wahlen vom Frühjahr 2019 nicht nur. Er schnitt mit einem - zumindest im ukrainischen Kontext - beschämenden Ergebnis in der Stichwahl ab. Vier Faktoren erklären das niederschmetternde Resultat Poroschenkos bei den Präsidentschaftswahlen 2019. Seine Nichterfüllung des Wählermandats, missglückte Kulturpolitik und Anwendung veralteter »politische Technologien« im Wahlkampf stellten Hindernisse für seine Wiederwahl dar. Hinzu kam der veränderte allgemeine gesellschaftliche Kontext des politischen Wettbewerbs in der Ukraine nach dem Sieg des Euromaidans und Beginn des Krieges mit Russland im Jahr 2014. Diese Kombination aus unproduktiven Strategien, schicksalhaften Fehlern und schwierigen Bedingungen war für die Wiederwahlkampagne Poroschenkos 2019 verhängnisvoll.
Das Ende der Debattenkultur?
Authors:   Maurer,   Jost
Published: November 2020

Der Beitrag untersucht die Folgen des Einzugs der Alternative für Deutschland (AfD) in den Bundestag für das Kommunikationsverhalten im Parlament. Dabei nehmen wir an, dass das Kommunikationsverhalten vor allem negativer und inziviler geworden ist und dass dies zwei Ursachen hat: Zum einen tritt die AfD als neue populistische Oppositionspartei negativer und inziviler auf als andere Parteien. Zum anderen haben sich die übrigen Bundestagsparteien diesem Kommunikationsstil zumindest partiell angepasst. Der vorliegende Beitrag prüft diese Annahmen mit einer Inhaltsanalyse von 2666 Absätzen aus 164 Bundestagsreden vor und nach dem Einzug der AfD in das Parlament. Die Analysen zeigen, dass die AfD etwas negativer, aber vor allem deutlich inziviler argumentiert als andere Oppositionsparteien. Vor allem die SPD-Redner haben ihr Kommunikationsverhalten partiell an das der AfD angepasst, sodass eine wechselseitige verbale Eskalation zwischen beiden Parteien zu beobachten war. Die Folgen dieser Veränderungen werden aus demokratietheoretischer Sicht diskutiert.
Ansätze und Aussichten einer sozial-ökologischen Transformation: Was verändert die Corona-Krise?
Authors: Ötsch Silke , Lehweß-Litzmann René
Published: November 2020

Multiple Krisen bedrohen die Reproduktionsfähigkeit von Umwelt und Gesellschaft. Ob sie in Form einer synergetischen Lösungsstrategie bewältigt werden, als konkurrierende Anliegen oder überhaupt nicht, ist ebenso unklar wie die Wechselwirkungen zur Corona-Krise. In letzter Zeit wird vermehrt vorgeschlagen, die Krisen mit Hilfe von New Deal-Politiken zu bearbeiten, die für umfassende politische Reformen mit sorgendem Anspruch stehen. Der europäische Grüne Deal und der Green New Deal etwa unterscheiden sich aber hinsichtlich der Rolle marktförmiger Steuerung und des Wirtschaftswachstums. Der Beitrag diskutiert das Potenzial solcher Ansätze und ihre Zustimmungsfähigkeit aus Sicht einer Bevölkerung, die sich unter dem Eindruck der Corona-Pandemie mit existenziellen sozioökonomischen Risiken konfrontiert sieht. Erste Umfragen zeigen, dass gleichwohl auch jetzt eine Mehrheit die umweltbezogene Reformnotwendigkeit sieht. Ausschlaggebend für dieses Bewusstsein scheint weniger der Wohlstand als die Gewährleistung grundlegender Funktionen der Lebensführung. Dies unterstreicht die Sinnhaftigkeit einer Kombination von Ökologischem und Sozialem im Politikangebot und verweist auf die grundsätzliche Möglichkeit einer Gesellschaft, die ökologische Grenzen und soziale Standards respektiert.

Role of Post-Harvest Physiology in Evolution of Transgenic Crops
Authors: Sharma Binny , Kumari Asha
Published: November 2020

The increasing world population over few decades has led to increase in demand of food grains or agricultural commodities, thus possessing great impact on food security. Conventional farming approaches has been traditionally practiced but a lot of effort is required to make to enhance agricultural production. With changing climatic conditions plants are vulnerable to several stress factors. In order to combat such conditions, the agricultural systems are needed to be contemporary with advance and recent technologies. Crops after harvest are liable to a lot of changes which ultimately affect quality and quantity of produce, thus reducing economic value. Postharvest losses are decisive factors in reducing loss of produce and agricultural commodities. Thus in order to achieve maximum production, it is therefore essential to reduce postharvest losses and ensures proper management of postharvest products. Postharvest physiology is the science which deals with quantitative and qualitative study of physiology of agricultural products after harvesting. Biotechnological and transgenic approaches are the recent and emerging technologies that possess great impact on agricultural production. Transgenic technology like genome editing, CRISPR/Cas9, TILLING are successfully used in various species to enhance production, possess resistance to abiotic and biotic stresses, enhance shelf life and improve nutritional quality. Transgenic crops or Genetically modified crops (GMO) like tomato, brinjal, soybean, cassava etc are cultivated globally. These techniques therefore are promising means in establishing food security, increasing crop production, reducing postharvest losses, production of secondary metabolites, hormones and plantibodies.

Background: Cardiac neoplasms are not common in the pediatric population, and most of the reported cases in the literature are benign. Despite their benign nature, however, cardiac neoplasms may lead to hemodynamic instability and arrhythmias. Objectives: Our study aimed to review the natural history, diagnosis, pathological features, and outcome of pediatric patients with cardiac tumors presenting to a tertiary pediatric cardiac center over an 8-year period. Methods: This retrospective observational study reviewed and analyzed the hospital records and data of pediatric patients diagnosed with cardiac tumors over an 8-year period (2007 - 2015). Results: During the period covered by the study (2007 - 2015), a total of 62975 pediatric in and out patients were referred to our tertiary cardiac center for cardiac evaluation. Cardiac tumors were identified in 41 patients, in 35 of whom tumor types were recognized. Rhabdomyomas were the most common tumors, followed by fibromas and myxomas. Fourteen patients underwent surgical management (either total or partial resection), and 4 patients received chemotherapy. Associated congenital heart diseases, except for the patent foramen ovale, were detected in12 patients. Conclusions: While almost all our findings were compatible with previous data, we had a comparatively large number of undetermined tumors. Therefore, a better understanding of the imaging characteristics of cardiac tumors is needed for a better diagnosis of tumor types via noninvasive modalities.

Male genitalia includes the penis, testicles and the prostate. Ultrasound is a basic method for prostate exam, due to its obscure position deep in the pelvis. On the other hand, penis and scrotal content are very available to physical examination, but thanks to proximity to surface of the skin, the high frequency ultrasound gives us clear picture of the interior of this organs and that is why we use this method for the confirmation of clinical diagnosis and in decision making for further treatment.

Background/Aims: Endoscopic resection (ER) has recently been accepted as the standard treatment modality for superficial nonampullary duodenal tumors (SNADTs). However, the procedure can cause adverse events such as perforation and bleeding. This study aimed to investigate the efficacy of prophylactic clipping in the prevention of delayed complications.Methods: A retrospective review of the medical records of patients who underwent ER for SNADT from 3 centers was performed. Patients were divided into 2 groups: the immediate clipping group (ICG) and the no clipping group (NCG). Various baseline characteristics and factors associated with the appearance of delayed complications, such as size of the lesion, tumor location, histologic type, and co-morbidities, were compared between the two groups.Results: A total of 99 lesions from 99 patients were included in this study. Fifty-two patients were allocated into ICG and 47 patients were allocated into NCG. Delayed bleeding occurred in 1 patient from ICG and in 8 patients from NCG. Delayed perforation occurred in 1 patient from ICG and in 3 patients from NCG. There were no procedure-related deaths in both groups.Conclusions: Although the use of endoscopic clipping seemed to reduce the risk of developing delayed complications, further studies using a prospective design is required.

Published: November 2020

Makroaļģes ir viens no lielākajiem nenovērtētajiem biomasas resursiem pasaulē. Tās ir iekļautas Eiropas Savienības “zilās izaugsmes” stratēģijā kā alternatīvs resurss, lai apmierinātu arvien augošo pieprasījumu pēc ilgtspējīgiem bioloģiskas izcelsmes materiāliem. Biorafinērijas koncepcijas pielietošana ļauj no biomasas iegūt produktus ar augstu pievienoto vērtību un biodegvielu. Baltijas reģionā makroaļģu audzēšana un izmantošana ir sākuma stadijā. Promocijas darbā tiek izvērtēta Baltijas jūras aļģu izmantošanas iespējas pielietojot biorafinērijas koncepciju. Darba gaitā autore attīsta pētījumu apskatot makroaļģes kā izejvielu, izvērtē biorafinērijā potenciāli iegūstamos produktus un to iegūšanas tehnoloģijas. Lai uzlabotu izejvielas pieejamību tiek izveidots laboratorijas stends makroaļģu kultivēšanai. Šī darba mērķis ir veikt integrētus pētījumus, lai novērtētu Latvijā pieejamo makroaļģu sugu iespējamu pielietojumu biorafinērijā. Šī darba ietvaros tiek veikti pētījumi, lai identificētu potenciālās jūras makroaļģu sugas, noskaidrotu iespējamo biomasas daudzumu un meklētu virzienu jūras aļģu izmantošanai tā, lai tā būtu daļa no valsts ekonomikas un tiktu atzīta par nozīmīgu biomasas veidu. Pētījuma veikšanai izvēlētas trīs indikatorsugas, kas pārstāv katru no trim galvenajiem aļģu tipiem. Promocijas darba pamatā ir septiņas tematiski vienotas zinātniskās publikācijas, kas publicētas dažādos zinātniskos žurnālos, un pieejamas zinātniskās informācijas datu krātuvēs un starptautiskajās datubāzēs. Šo publikāciju mērķis ir identificēt Latvijā esošās jūras aļģu sugas un meklēt virzienu jūras aļģu izmantošanai. Darba ievads iepazīstina ar darba mērķi un izvirzītajiem uzdevumiem, apraksta darba struktūru un sniedz pārskatu par autora praktisko un zinātnisko ieguldījumu. Pirmā nodaļa sniedz pārskatu par zinātnisko literatūru, iepriekšējiem pētījumiem un koncentrējas uz makroaļģu biomasas īpašībām. Iegūtie rezultāti un diskusija ir doti trešajā nodaļā.

In this work results are given for the experimental investigation of the me-chanism of cavitation emulsification by means of high-speed photography. The results show that: 1) Two fundamental types of cavitation emulsification occur simultaneously at the moment of a single cavitation bubble collapse. It thus appears that: emulsifica-tion is induced by the shock waves generated in liquids at the moment of cavitation bubble collapse; 2) In contrast with the "suction" model suggested by Nedouzhii, the process of cavitation emulsification would be better described by a "crushing" model.

Published: November 2020

The method which Wigner used for the classification of supermultiplets has been generalized to the excited energy spectrum of hypernuclei. The general form of two-body interaction is obtained which approximately does not break the SU6=SU3?SU2 classification and the coefficients in each of its term are determined from the experimental scattering data. The formula for the energy matrix element under SU6 is also derived. For 9ΛBe*,10ΛBe* and 10ΛΛBe*, some concrete calculations aregiven. We find that 9ΛBe* states seem to agree qualitatively with experiment.

Published: November 2020

In this paper, we have solved the Eliashberg equation for T=Tc, obtaining a series expression for the superconducting critical temperature Tc=α0(μ*)(λ〈ω2〉)1/2{1+1/λα1(μ*)〈ω4>/〈ω2>2+1/λ2(α21(μ*)〈ω6>/〈ω2>3+α22(μ*)〈ω4>2/〈ω2>4) +1/λ3(α31(μ*)〈ω8>/〈ω2>4+α32(μ*)(〈ω4>〈ω6>)/〈ω2>5)+α33(μ*)〈ω4>3/〈ω2>6+……}, where α0(μ*), α1(μ*) etc. depend upon μ* only. This new Tc formula shows that Tc is determined not only by λ, 〈ω2〉 and μ*, but also by the various moments 〈ω2n〉 of the effective phonon spectrum.

ELECTRON DIFFRACTION ANALYSIS OF THE TWIN AND HCP PHASE FORMED IN A FCC CRYSTAL
Authors: GUO KE-XIN  ,   中国科学院金属研究所
Published: November 2020

1. After transforming the zone axis [uvw] of a FCC crystal into [utvtwt] of its twin or [u′v′w′] of the HCP phase formed in it, it is possible to recognize immediately from these indices whether the electron diffraction pattern of the latter is distinct from that of the former.2. The qpndition for the twin to have a non-distinct pattern is: u(t2)+v(t2)+w(t2)>u2+v2+w2. 3. The condition for the HCP phase to have a non-distinct pattern is: u′,v′≠3n, u′+v′=3n. 4. As far as the low zone indices (u, v, w≤4) electron diffraction patterns of a FCC crystal are concerned, approximately 80% of the twin or HCP phase are not discernible by electron diffraction analysis.

Authors: YAO XI-XIAN  ,   南京大学物理系
Published: November 2020

In the presence of external sources, a superconducting weak link can be represented by a simplified model, consisting of a resistively shunted Josephson junction driven by a current source. We give in this paper, an analytical solution of the problem, in the case that the source current has both d. c. and a. c. components. As preliminary applications of our solution, we have also discussed square law detection and current steps of zero average voltage on the I-V characteristic, as the dimensionless a. c. component is small.
ON THE THEORY OF SECOND ORDER PHASE TRANSITION AND AN EXPOSITION ON THE NON-VALIDITY OF LIFSHITZ CONDITION
Authors: SHEN JUE-LIAN  ,   中国科学院物理研究所
Published: November 2020

We assume that the free energy of the system is a functional of order parameter. In the vicinity of second order transition, the free energy density can be expanded as a power series of order parameter as well as its correlation term. Following the pro-cedure given here, for both local and non-local, the order parameter representing equilibrium configuration can be found from the vanishment of the first variation of free energy. In order to find out the solution, it is necessary to carry out Fourier transform for order parameter, and this is identical to expand the order parameter in terms of the base functions of symmetric group of the system. In this way, we analyse the change of symmetry in second order transition.By making use the necessary and sufficient condition (or sufficient condition) for extrema in the variational procedure, the condition of stability for states in second order transition is discussed. Because the correlation term has not been neglected in the procedure of finding extrema, so that the restrictions condition of Lifshitz on sym-metry changing does not come into being. It should be pointed out that, in Lifshitz approach the correlation term is neglected in obtaining the minimum of free energy functional, whereas it is included in discussing the problem of stability. Therefore, Lifshitz's approach is inconsistent in itself. Furthermore, there exists certain kinds of system (such as one component axial vector system), in which the correlation term that leads to the Lifshitz condition cannot be constructed from order parameter. Nevertheless, Lifshitz and others also put restrictions on such system. This is obviously unreasonable. By making use the general theoretical approach described above, we explain the experimental results of phase transition in heavy lanthanide metals at Neel point. It serves as an example to show that there are second order phase transition phenomena for which Lifshitz's approach fails to explain.

Published: November 2020

In this work, the expressions of molecular dissociation rate and isotope enrichment coefficient in an strong IR field, as the functions of the laser energy per pulse, the focal length of lens, the number of laser pulses, and etc., were derived by using the kinetic theory. The theoretical expression of isotope enrichment coefficient was compared with the experimental results for SF6, and good agreement was found. In addition, the theoretical expressions compared with experiments would provide some useful informations of the molecular dissociation in the strong IR field.
