THE RELIABILITY ANALYSIS OF PEAT MACHINES FOR MILLING METHOD OF PRODUCTION
Authors:   Tver State Technical University, GORLOV I.V.
Published: December 2020

The methodology for determining of the reliability parameters of peat machines that do not have sufficient statistical data on operation has been proposed. The proposed approach will permit to determine the change of the technical status of a wide range of peat machines for the milling method of extraction. It will enable peat enterprises to operate taking into account their individual condition and plans for the peat production, and will permit to carry out the major repairs of technological equipment in the autumn-winter period without decreasing the works productivity in the mining season. For peat machines that do not have enough statistical data to analyze their operation, one can use the generalized data on similar peat machines to obtain approximate dependencies which permit to predict changes in the technical state of the equipment under study with some accuracy. With an increase of statistical data amount, it is proposed to use the coefficient method using operational data. It permits to improve the quality of forecasting and as a result to reduce the number of downtime due to failures and to increase the seasonal productivity of peat machines.

REFORMING DOMESTIC HEALTH CARE IN THE 1920–1930s ON THE EXAMPLE OF THE CHUVASH ASSR (criticism of historiographical sources)
Authors: Kezhutin Andrei N.
Published: December 2020

The article reveals the features of implementing the state project of reforming domestic medicine on the materials of the Chuvash ASSR. The relevance of the study is due to insufficient extent of previous investigations on this topic in the Russian historiography, as well as permanent reforming of the Russian health care system in modern times, searching for the optimal form of organizing medical aid and social security in the Russian Federation. The article examines the social processes of the frontier of 1920–1930s, which directly influenced the development of the medical sphere. The study of the problem is connected with the analysis of mass social diseases spread as catalysts of a large-scale restructuring of health care in conjunction with the processes of social-economic development of the society. The author identifies the main approaches of domestic and foreign scientists to the problem of public health preserving. Archival data on the state and development of the healthcare system of the Chuvash ASSR are introduced into scientific circulation.

Authors: Iskhakov Radik R.
Published: December 2020

In the conditions of “narrowing” the field of using the national languages of the Middle Volga region peoples, the study of historical experience of their use as a channel of cultural modernization and westernization of the society in the pre-revolutionary period is a topical subject of research. The purpose of the work is to analyze retrospectively the activities to translate and publish secular educational material and periodical press in the Chuvash language in Kazan in the late-imperial period (1905–1914). Liberalization of Caesarism’s internal politics during the First Russian Revolution, as well as emancipation of social consciousness of the national intelligentsia created favorable conditions for the appearance of the first periodicals and secular literature in the Chuvash language. One of the education centers, where at this time new Chuvash editions began to be published, was Kazan. The first Chuvash newspaper “Khypar” was published there as well as annual calendars, the Translation Commission under Kazan educational district organized translation and printing secular educational literature.

Within the framework of this study, for the first time in the Russian historiography, the author makes an attempt to assess the role of Kazan in the formation of the Chuvash secular educational book and newspaper periodicals in pre-revolutionary period, he studies the activity of the Translation Commission under Kazan Educational District on compiling and printing secular educational literature, he shows the repertoire, the circulation and the years of Chuvash editions release. As a result of the study, it was concluded that the formation of secular book printing and the appearance of the first periodic organs in the Chuvash language played a significant role in the birth of the national movement and the growth of self-awareness in the Chuvash people.

Published: December 2020

The main objective of this research consists in studying psychosocial aspects of the relationship that is established between the level of the quality of self image and self-esteem in adolescents. Self-esteem play an important role in the self image of teenagers and young people. Teenagers with a high level of self-esteem have clear and stable views about themselves, talk about them in a consistent, positive way. Teenagers with a low self-esteem have the feeling that they do not know too well each other and talk about them in a unreliable and ambiguous way. They are also pretty reserved in initiating social contacts.

Web 2.0 Applications designed to integrate the Conceptual Maps into the Teaching Activity
Authors: Chicioreanu Teodora Daniela
Published: December 2020

The typical representative of today's youth generation (NET Generation) spends over 20,000 hours on the internet and over 10,000 hours enjoying online games of all sorts before turning 20 years old. This is why a series of web 2.0 applications were and will continue being created greatly focusing on the visual and spatial performances, improving and developing collaborative work. In the educational process, the elaboration of conceptual/mind maps helps pupils/students organise and represent their concepts in a manner tailored to the understanding ability. By means of these maps, the pupils/students can correlate the concepts in a variety of ways valuing and stimulating the creativity and originality, thus integrating such concepts in their own individual notional systems. For the Teacher, this type of investigation is a means to periodically perform true "incursions" into the pupils /students' intellectual acquisitions, this being an overall reflection of how the specific concepts are understood and correlated. Knowing and using WEB 2.0 applications which facilitate this (the elaboration of conceptual maps) and integrating them into the teaching activity is essential for any teacher willing to stay up-to-date with the latest novelties and innovations in the field. In conclusion, several ideas will be provided concerning the use of such technologies in education, all of which are integrated by the article author in her teaching activity.
Patru competențe cheie – Posibil cadru de referință pentru curriculumul integrat
Authors: Țîmpău Cristina Tripon
Published: December 2020

What are the capabilities that have been identified and defined as transversal competences? One view is that any skills that are essential for navigating life could be classed as transversal competences. This does not mean that many familiar skills of the 20th and preceding centuries are no longer needed. But there are new skills emerging as increasingly important. Competence encompasses the quality and transferability of that action over time and context. No one performs a skill at the same level every time. No one operates at their maximum all the time.
Abordări pragmatice în educația modernă: Educația despre standardizare
Authors: Chină Remus
Published: December 2020

In recent years there were in educational environments, intense debates on two major topics and trends related to standards and standardization: standardization in education and education about standardization. These trends were enabled, in our view, by the accelerated pace of implementation in everyday life of scientific and technical discoveries as well as by the higher development rate of economic and business environments in respect to the educational environments. Another reason for the development of these trends is the need for a more efficient correlation between the labor market needs and the offer of educational environments.

This paper aims to investigate the psychological well-being in relation to group socio-cognitive factors at work. Data was collected on a sample of 133 participants that were employed and had a manager at the time of filling in the scales. The results support the mediation role of trust between transformational and organizational identification. Organizational identification totally mediated the relationship between transformational leadership and psychological well being and its subscales: purpose in life, positive relationships with others, environmental control. The relationship between transformational leadership and self acceptance, personal growth and positive relations with other was mediated by the trust in coworkers.

Published: December 2020

This article examines the role of self-concept clarity within the self-assessment of both general intelligence and emotional intelligence and the relation between the results of said tests and the self-concept clarity of participants. The objectives of this study are as follows: (1) the preliminary adaptation of the self-concept clarity scale for use with the Romanian population, (2) the reproduction of previous results concerning the correlations between the self-assessments of participants and the results obtained after psychometric testing on a Romanian sample, (3) research into the existence of a negative correlation between self-concept clarity levels and the errors of participants’ self-assessments and (4) the exploration of the relationship between self-concept clarity and the tests used in this study. The sample used in the study was composed of 157 participants that were assessed online with the self-concept clarity scale, were asked to self-assess their general and emotional intelligence levels and then took the GAMA (general intelligence), MSCEIT and EQ-i (emotional intelligence) tests. The results of the study indicate a significant relation between self-concept clarity and the GAMA, MSCEIT and EQ-i test results and encourage further research into the role of self-concept clarity in the self-assessment process.
The role of adverse childhood experiences, self control and Dark Triad in the development of criminal behaviour. Correlative and differential aspects
Authors: Merlușcă Bogdan-Ioan , Chiracu Alina
Published: December 2020

This research consists of two studies that aimed primarily on identifying the links between adverse childhood experiences, the level of self-control, the „dark” personality traits, and also their relationship with criminal behavior. In the first study we aimed to establish a relationship between all the variables. A sample of 232 psychology students participated in the research. They reported that they experienced a number of emotional adverse events in their childhood, and these events were positively associated with low levels of self-control and dark personality traits. The second study aimed to replicate the results obtained in the first study. Furthermore, we want to see the differences related to these variables between inmates and psychology students. In this study participated 87 inmates and 87 psychology students. The results showed that inmates predominantly experienced adverse childhood events of a physical nature, while students predominantly experienced adverse emotional events. It has been shown that psychopathy has been positively associated with offending behavior and the high frequency of adverse childhood events. The low level of self-control has been positively associated with adverse childhood events and negative personality traits. Further studies are needed in order to establish students' sensitivity thresholds in relation to adverse childhood events and to clarify the impact these events have had on students.
Grit utility in explaining job and contextual performance
Authors: Peleașă Steluța
Published: December 2020

The study aims to analyze if grit brings incremental validity in the prediction of job performance criteria (task performance, organizational citizenship behaviors and counterproductive work behaviors), in addition to some classical predictors such as emotional intelligence and some personality factors (conscientiousness and agreeableness). The sample consists of 170 employees from various fields of activity. Regression analysis has shown that grit has no incremental validity to personality and emotional intelligence in predicting any of the work performance criteria (task performance, organizational citizenship behaviors and counterproductive work behaviors). The study therefore brings to the academic literature one more proof for the fact that it is difficult to consider grit an independent, self-constructed concept.
Comparative Evaluations of Performance and Self-esteem as Determinants of Job Insecurity
Authors: Postelnicu Maria Daniela , Grigore Oana Maria
Published: December 2020

Job insecurity is a toxic stressor brought forward by the world’s financial crisis. The purpose of this study is to demonstrate that comparative judgements predict a unique percentage of job insecurity’s variance, above self esteem. Subsequently, questionnaires were applied via social media or via paper-pencil to 108 participants. Hierarchical regression results show that comparative judgements do not have any incremental effect in predicting job insecurity above self esteem. Self esteem predicts 21% variance in job insecurity. In conclusion, job insecurity is predicted by how individuals globally evaluate themselves, with comparative judgements regarding one’s own performance or the company’s performance having no incremental predictive power. These two variables can be regarded as undifferentiated from self esteem.
The role of intelligence in the relationship between attachment styles and cognitive schemas in psychotherapists
Authors: Corduneanu Virginia
Published: December 2020

The present study aims to analyze the relationships between attachment styles (avoidant and anxious) and cognitive schemas and also the role of intelligence in this relationship. The participants of the study were 62 psychologists or future psychologists aged between 23 and 51 years, M = 34.38, SD = 7.18. Of these, 12 were psychology students, 54 were autonomous psychologists, and two were experimented psychologists. Four of the participants were men, and 68 were women. As for marital status, 23 were unmarried, 19 were in a relationship, and 30 were married. The instruments used were The Attachment Style Questionnaire, ASQ (α = .94), Young Cognitive Schema Questionnaire - Short Form, YSQ-S3 (α = .98), and Analogical Transfer Test (CAS++) for the measurement of intelligence. The results showed that avoidant and anxious attachment styles are positively associated with the development of maladaptive cognitive schemas in all the five domains. Intelligence does not moderate the relationship between attachment styles and cognitive schemas. In the personal development of psychologists and psychotherapists, it is necessary to augment maladaptive cognitive schemas through specific psychoeducational programs. Further studies are needed to identify other factors that may be involved in the development of cognitive schemas.
Dark triad of personality and aggression in adolescents and young people
Authors: Gogoriță Constantin
Published: December 2020

The present study aims to analyze the relationships between dark triad of personality and aggression in adolescents. Aggression is considered the key factor in the development of criminal behavior, and by deciphering the factors that determine aggression, interventions can be made to prevent and diminish delinquent behavior. In this study, 134 persons between 15 and 28 years old participated, M = 20.48, AS = 2.50, of whom 34 were males and 79 were females. The instruments used to assess the dark personality traits and aggression were The Aggression Questionnaire, BPAQ (α = .89) and Short Dark Triad, SD-3 (α = .79). The results showed that boys have higher levels of physical aggression than girls, while girls have higher levels of anger and hostility than boys. In addition, psychopathy was positively associated with physical aggression, verbal aggression, and anger, Machiavelianism was positively associated with hostility, and narcissism was negatively associated with hostility. Age moderates to some extent the relationship between dark personality traits and physical aggression. Practical implications of these results are disscused.

Published: December 2020

O presente artigo tem como objetivo analisar as relações intrageracionais de alunos do 5º ano da “EMEF Adão Benezath”. Ele nasceu das experiências vividas no Programa Institucional de Bolsas de Iniciação á Docência, sobretudo, no momento em que realizamos as intervenções nas práticas cotidianas. A metodologia foi qualitativa do tipo estudo de caso e tem como instrumento a observação com registros com o diário de campo. As observações evidenciam a necessidade de desnaturalizarmos o olhar adultocêntrico no sentido de ver com estranhamento aquilo que se apresenta como comum nesse caso algumas brincadeiras que caracterizamos como brigas ou desentendimentos entre os alunos. Nesse movimento, percebemos que a violência entre os alunos, muitas vezes, ocorria em brincadeiras de lutas, acompanhadas de disputas por espaço, lugar e poder.

O presente artigo se propôs a apresentar uma prática de ensino da Geografia no âmbito do Programa Residência Pedagógica em Geografia, da Universidade Federal do Espírito Santo (UFES), com estudantes do 6º ano de uma escola-campo, localizada no município de Vila Velha/ES. A atividade descrita neste artigo fundamenta-se na reflexão da práxis preconizada por Freire (2001) e tem como objetivo relacionar os limites e possibilidades da aula de campo e suas contribuições para o desenvolvimento crítico e dialógico do ensino da Geografia com o ambiente no qual os estudantes estão inseridos. Baseia-se na dificuldade de compreensão e entendimento de forma integrada do ensino teórico da Geografia com o dia a dia dos(as) estudantes. A metodologia adotada apoia-se na Pesquisa com o cotidiano de Ferraço (2007) e Alves (2001). O percurso metodológico ocorreu em três etapas: o pré-campo, o campo e o pós-campo, que resultou na produção de histórias em quadrinhos sobre a temática estudada. Constatou-se a importância da aula de campo para a compreensão fora da escola, o que é estudado dentro dela e que a adoção deste tipo de metodologia potencializa o ensino da Geografia e motiva os estudantes a uma postura crítico-reflexiva, ao dinamizar o processo de ensino-aprendizagem.
The situation of geography teachers on the labour market in Poland: overt and covert issues
Authors:   Pedagogical University of Kraków, Poland, PIRÓG Danuta , HIBSZER Adam ,   University of Silesia in Katowice, Poland
Published: December 2020

Economic, social and cultural changes generate new challenges on the labour market for teachers in every country. Poland has recently witnessed significant changes in factors that were identified in literature as crucial to the situation of teachers on the labour market, such as systemic reforms, demographic trends, the overall situation on the labour market and occupational prestige. The scale and impact of some of these factors can be precisely measured and statistically accounted for, yet there are others that remain somehow hidden. The objective of the article is to present and analyse the current situation of geography teachers in Poland, taking into account the impact of both overt and covert factors. The paper is based on an analysis of primary and secondary data. Primary data were collected during our own research on online job advertisements and revolved around information on the real demand for geography teachers. Secondary data were official reports and statistics related to the social and professional standing of teachers in Poland. The analysis proves that in the last ten years the population of teachers has aged and experienced a drop in real wages. There has also been an increase in staff turnover and patchwork careers. Moreover, we have observed that it is highly unlikely to secure a full-time position as a geography teacher and that there have been huge fluctuations in the prestige of geography as a school subject. The identified changes can result in a shortage of qualified geography teachers in the short term, particularly in cities

Authors:   University of Ljubljana, Slovenia, ILC KLUN Mojca
Published: December 2020

Slovenia, one of the smallest European countries, has always been part of various migration processes. As these processes are nowadays an important part of politics and our everyday life, the topics of migration need to be included in the school curricula. The paper presents an example of how educators can teach young people about migration processes through gamification, using an innovative, didactic and strategic board game Crossing Borders. When playing Crossing Borders, players subconsciously learn about the migration-related topics. The game was very well received among all test groups (teachers and students).

The debate among economists about an optimal growth recipe has been the subject of competing “narratives.” We identify four major growth narratives using the text analytics of IMF country reports over 1978-2019. The narrative “Economic Structure”—services, manufacturing, and agriculture—has been on a secular decline overshadowed by the
“Structural Reforms”—competitiveness, transparency, and governance. We observe the rise and fall of the “Washington Consensus”—privatization and liberalization— and the rise to dominance of the “Washington Constellation,” a collection of many disparate terms such as productivity, tourism, and inequality. Growth theory concepts such as innovation, technology, and export policy have been marginal while industrial policy, which was once perceived positively, is making a comeback.
Constrained Efficient Borrowing with Sovereign Default Risk
Authors: Hatchondo Juan Carlos , Martinez Leonardo , Roch Francisco
Published: December 2020

Using a quantitative sovereign default model, we characterize constrained efficient borrowing by a Ramsey government that commits to income-history-contingent borrowing paths taking as given ex-post optimal future default decisions. The Ramsey government improves upon the Markov government because it internalizes the effects of borrowing decisions in period t on borrowing opportunities prior to t. We show the effect of borrowing decisions in t on utility flows prior to t can be encapsulated by two single dimensional variables. Relative to a Markov government, the Ramsey government distorts borrowing decisions more when bond prices are more sensitive to borrowing, and changes in bond prices have a larger effect on past utility. In a quantitative exercise, more than 80% of the default risk is eliminated by a Ramsey government, without decreasing borrowing. The Ramsey government also has a higher probability of completing a successful deleveraging (without defaulting), while smoothing out the fiscal consolidation.

Abstract. We address the problem of identifying the evaporation rates for neutral molecular clusters from synthetic (computer-simulated) cluster concentrations. We applied Bayesian parameter estimation using a Markov chain Monte Carlo (MCMC) algorithm to determine cluster evaporation/fragmentation rates from synthetic cluster distributions generated by the Atmospheric Cluster Dynamics Code (ACDC) and based on gas kinetic collision rate coefficients and evaporation rates obtained using quantum chemical calculations and detailed balances. The studied system consisted of electrically neutral sulfuric acid and ammonia clusters with up to five of each type of molecules. We then treated the concentrations generated by ACDC as synthetic experimental data. With the assumption that the collision rates are known, we tested two approaches for estimating the evaporation rates from these data. First, we studied a scenario where time-dependent cluster distributions are measured at a single temperature before the system reaches a steady state. In the second scenario, only steady-state cluster distributions are measured but at several temperatures. Additionally, in the latter case, the evaporation rates were represented in terms of cluster formation enthalpies and entropies. This reparameterization reduced the number of unknown parameters, since several evaporation rates depend on the same cluster formation enthalpy and entropy values. We also estimated the evaporation rates using previously published synthetic steady-state cluster concentration data at one temperature and compared our two cases to this setting. Both the time-dependent and the two-temperature steady-state concentration data allowed us to estimate the evaporation rates with less variance than in the steady-state single-temperature case. We show that temperature-dependent steady-state data outperform single-temperature time-dependent data for parameter estimation, even if only two temperatures are used. We can thus conclude that for experimentally determining evaporation rates, cluster distribution measurements at several temperatures are recommended over time-dependent measurements at one temperature.

Abstract. Accurate boundary layer structure and height are critical
in the analysis of the features of air pollutants and local circulation.
Although surface-based remote sensing instruments provide a high temporal
resolution of the boundary layer structure, there are numerous uncertainties
in terms of the accurate determination of the atmospheric boundary layer
heights (ABLHs). In this study, an algorithm for an integrated system for
ABLH estimation (ISABLE) was developed and applied to the vertical profile
data obtained using a ceilometer and a microwave radiometer in Seoul city,
Korea. A maximum of 19 ABLHs were estimated via the conventional
time-variance, gradient, wavelet, and clustering methods using the
backscatter coefficient from the ceilometer. Meanwhile, several stable
boundary layer heights were extracted through near-surface inversion and
environmental lapse rate methods using the potential temperature from the
microwave radiometer. The ISABLE algorithm can find an optimal ABLH from
post-processing, such as k-means clustering and density-based spatial
clustering of applications with noise (DBSCAN) techniques. It was found that
the ABLH determined using ISABLE exhibited more significant correlation
coefficients and smaller mean bias and root mean square error between the
radiosonde-derived ABLHs than those obtained using the most conventional
methods. Clear skies exhibited higher daytime ABLH than cloudy skies, and
the daily maximum ABLH was recorded in summer because of the more intense
radiation. The ABLHs estimated by ISABLE are expected to contribute to the
parameterization of vertical diffusion in the atmospheric boundary layer.

Abstract. The Early Cretaceous is characterized by warm background temperatures (i.e., greenhouse climate) and carbon cycle perturbations that are often marked by Ocean Anoxic Events (OAEs) and associated shifts in the hydrologic cycle. Higher-resolution records of terrestrial and marine δ13C and δ18O (both carbonates and organics) suggest climate shifts during the Aptian-Albian, including a warm period associated with OAE 1a in the early Aptian and subsequent cold snap near the Aptian-Albian boundary prior to the Kilian and OAE 1b. Understanding the continental system is an important factor in determining the triggers and feedbacks to these events. Here, we present new paleosol carbonate stable isotopic (δ13C, δ18O and Δ47) and CALMAG weathering parameter results from the Xiagou and Zhonggou Formations (part of the Xinminpu Group in the Yujingzi Basin of NW China) spanning the Aptian-Albian. Published mean annual air temperature (MAAT) records of the Barremian-Albian from Asia are relatively cool with respect to the Early Cretaceous. However, these records are largely based on coupled δ18O measurements of dinosaur apatite phosphate (δ18Op) and carbonate (δ18Ocarb), and therefore rely on estimates of meteoric water δ18O (δ18Omw) from δ18Op. Significant shifts in the hydrologic cycle likely influenced δ18Omw in the region, complicating these MAAT estimates. Thus, temperature records independent of δ18Omw (e.g., clumped isotopes or Δ47) are desirable, and required to confirm temperatures estimated with δ18Op and δ18Oc, and to reliably determine regional shifts in δ18Omw. Primary carbonate material was identified using traditional petrography, cathodoluminescence inspection, and δ13C and δ18O subsampling. Our preliminary Δ47-based temperature reconstructions (record mean of 14.9 ºC), which we interpret as likely being representative of MAAT, match prior estimates from similar paleolatitudes of Asian MAAT (average ~15 ºC) across the Aptian-Albian. This, supported by our estimated mean atmospheric paleo-pCO2 concentration of 396 ppmv, indicates relatively cooler mid-latitude terrestrial climate. Additionally, our coupled δ18O and Δ47 records suggest shifts in the regional hydrologic cycle (i.e., ΔMAP and Δδ18Omw) that may track Aptian-Albian climate perturbations (i.e., a drying of Asian continental climate associated with the cool interval).
Emergent constraints on equilibrium climate sensitivity in CMIP5: do they hold for CMIP6?

Abstract. An important metric for temperature projections is the equilibrium climate sensitivity (ECS), which is defined as the global mean surface air temperature change caused by a doubling of the atmospheric CO2 concentration. The range for ECS assessed by the Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report is between 1.5 and 4.5 K and has not decreased over the last decades. Among other methods, emergent constraints are potentially promising approaches to reduce the range of ECS by combining observations and output from Earth System Models (ESMs). In this study, we systematically analyze 11 published emergent constraints on ECS that have mostly been derived from models participating in the Coupled Model Intercomparison Project Phase 5 (CMIP5) project. These emergent constraints are – except for one that is based on temperature variability – all directly or indirectly based on cloud processes, which are the major source of spread in ECS among current models. The focus of the study is on testing if these emergent constraints hold for ESMs participating in the new Phase 6 (CMIP6). Since none of the emergent constraints considered here have been derived using the CMIP6 ensemble, CMIP6 can be used for cross-checking of the emergent constraints on a new model ensemble. The application of the emergent constraints to CMIP6 data shows a decrease in skill and statistical significance of the emergent relationship for nearly all constraints, with this decrease being large in many cases. Consequently, the size of the constrained ECS ranges (66 % confidence
intervals) widens by 51 % on average in CMIP6 compared to CMIP5. This is
likely because of changes in the representation of cloud processes from
CMIP5 to CMIP6, but may in some cases also be due to spurious statistical
relationships or a too small number of models in the ensemble that the emergent
constraint was originally derived from. The emergently- constrained best
estimates of ECS also increased from CMIP5 to CMIP6 by 12 % on average.
This can be at least partly explained by the increased number of high-ECS
(above 4.5 K) models in CMIP6 without a corresponding change in the constraint predictors, suggesting the emergence of new feedback processes
rather than changes in strength of those previously dominant. Our results
support previous studies concluding that emergent constraints should be
based on an independently verifiable physical mechanism, and that process-based emergent constraints on ECS should rather be thought of as
constraints for the process or feedback they are actually targeting.

Abstract. The Martabe deposits in Sumatra, Indonesia formed in a shallow crustal epithermal environment (200–350 °C) associated with mafic intrusions, usually recognised in domes, adjacent to an active right-lateral wrench system. Ten samples containing alunite were collected for high-resolution 40Ar/39Ar geochronology, to determine if overprinting fluid systems could be recognised. At the same time, ultra-high-vacuum (UHV) furnace step-heating 39Ar diffusion experiments were conducted, to determine the argon retentivity of the mineral grains being analysed. The heating schedule chosen to ensure Arrhenius data uniformly populated the inverse temperature axis, with sufficient detail to allow the application of the Fundamental Asymmetry Principle (FAP) during data analysis. The heating time for each step was chosen to ensure reasonable uniformity in terms of incremental percentage gas release during each step. Results show activation energies between 360–500 kJ/mol, with normalised frequency factor between 1.89e14s−1 and 8.62e18s−1. Closure temperatures range from 390–519 °C for a cooling rates of 20 °C/Ma, giving confidence that the ages represent growth during periods of active fluid movement and alteration.

chemical equations into differential form for use in atmospheric chemical
transport models (CTMs) and/or the boxChem system. Although GenChem is
primarily intended for users of the Meteorological
Synthesizing Centre – West of the European Monitoring and Evaluation
Programme (EMEP MSC-W) CTM and related systems,
boxChem can be run as a stand-alone chemical solver, enabling for example
easy testing of chemical mechanisms against each other. This paper
presents an outline of the usage of the GenChem system, explaining input
and output files, and presents some examples of usage. The code needed to run GenChem is released as open-source code under the GNU license.
