RARE FOREST PLANT COMMUNITIES OF THE NATIONAL PARK «PRIPYSHMINSKY BORY» (SVERDLOVSK REGION)
Authors:   ral Federal University named after the first President of Russia B. N. Yeltsin, Tretyakova A.S.
Published: November 2020

The article deals with rare forest plant communities of the National Park «Pripyshminsky Bory» in the Sverdlovsk Region. Rare forest plant communities include valuable areas of spruce, pine and birch forests. Among the unique and rare, we propose to include communities with Dianthus krylovianus and communities with Calluna vulgaris. The authors gave the phytocenotic characteristic of each community and the composition of rare and protected plants. These communities can be classified as rare based on a set of criteria, which includes species richness, the presence of rare species, and scientific importance. This information can become the basis for monitoring the status of rare and endangered plant species in the region.

The Department of Botany and Dendrology of the oldest educational forestry institution of Russia, the present St. Petersburg State Forest Technical University named after S.M. Kirov, is celebrating its centenary. At the time of its foundation it was the first specialized department of this kind both in Russia and in the world. In the course of its historical development, the Department of Botany and Dendrology has been formed not only as a large educational and methodological center for botanical, dendrological and general biology training. It has also become a major scientific center providing a wide range of research in the field of biology and ecology of woody plants, their introduction, intraspecific polymorphism, selection, phenological biorhythm, forest science, floristics and taxonomy, anthropogenic dynamics of plant cover and biodiversity conservation of forest ecosystems, bioindication, bioclimatology, forest phenology, and dendrophenological forecasting. It is impossible to list scientific publications of the Department, for only V.N.Sukachov alone was the author of about 500 papers. Under the leadership of V.N.Sukachev, his students and followers, provided research training and supervision for about 50 doctors and candidates of sciences, most of whom specialized in dendrology. Already in itself this fact testifies that creating the first in Russia Department of dendrology, V.N.Sukachev looked far ahead into addressing botanical and dendrological problems of Russia. Only within the last 10-15 years, the staff of the Department published 10 monographs, 2 textbooks, more than 10 teaching manuals. The geography of scientific research is constantly expanding. The scientific school “Dendrology and Biogeocenology named after V.N.Sukachev” has been established and is functioning at the Department.
ECONOMIC AND ENVIRONMENTAL ASPECTS OF FOREST LEASE ON THE EXAMPLE OF MORDOVIA REPUBLIC
Authors:   Volga state university of technology, Chernyakevich L.M. , Vdovin E.S. ,   Plyterra CJSC
Published: November 2020

The article analyses the impact of the lease model of relations in forestry on the economic and environmental impact of its management. The existing low economic efficiency of forestry of the Republic of Mordovia and negative ecological trends require a revision of the forest management model. The forest sector of Mordovia failed to create a competitive market environment. The lease relationship did not create conditions to increase the profitability of timber production through its innovative development. The fact is that low payment rates of timber put the economic barrier on the way to modernization of timber production, stimulating the preservation of backward, inefficient technologies in the field of wood harvesting and processing, in which a large amount of waste is generated, there is low productivity, non-competitive products are produced in export markets. Also, the ecological condition of forests continues to deteriorate as a result of the development of lease relations in the region. The authors of the article consider that a concession model should replace the lease model of forest management. Its use will increase the profitability of forestry, as the concession payment for forest use will most rightly correspond the cost of consumed resources in the region, as well as take into account the unique natural characteristics of the territory used.
STATE OF THE FOREST OF BETULA PENDULA ROTH. IN THE SUBURBAN STANDS OF KRASNOYARSK FOREST-STEPPE
Authors:   Reshetnev Siberian State University of Science and Technology, Tatarintsev A.I.
Published: November 2020

The state of stands of B. pendula under conditions of chronic technogenic pollution was studied. Initial datamaterials of a detailed survey of plantings on five permanent trial areas: four-in suburban plantings, one-in birch forests on a transparent background. Surveys were performed in 2008 and 2018. Some calculated indicators assessed the state of stands, the main one being the index of life status. In 2008, a satisfactory state of suburban plantings was established, with no significant differences with the state of the control plantings. The state of stands has deteriorated in recent years (according to 2018 data), incredibly critically – in extreme biotopes (arid hydrothermal conditions, man-made pollution, recreational load). This is due to the decreased resistance of trees B. pendula, but increased the cumulative impact of these limiting factors, further – an increase of activity of pathogens and insects of phyllophagous due to the process of global warming.

The results of the study of the thermal structure of early and latewood in the annual rings formed in 1993-2002 in the trees of Arctic white birch (Betula tortuosa Ledeb) and Siberian larch (Larix sibirica Ledeb) grows in the alpine tundra ecotone of The Kuznetsky Alatau. An analysis of the correlation between thermodynamics and mean temperatures and precipitation showed that mainly the June-August weather conditions determine the component composition of early and late birch wood. Air temperature has a noticeable influence on the component composition during the synthesis of cell walls of early and latewood, precipitation - late. The component composition of the early and late foliage trachea was not as sensitive to changing weather conditions. The evaporation rate of the bound latewood water is only observed to be dependent on summer temperatures.

Authors:   Institute of Slavic Studies, Russian Academy of Sciences, Gusev Nikita S.
Published: November 2020

The book examines the place that Bulgaria and Serbia took in the life of Russian society during the Balkan wars of 1912-1913. The war of the Orthodox peoples of the Balkans against the Ottoman Empire stirred up Russian society. The media closely monitored the events, public lectures and meetings devoted to the war were held, donations, volunteers and Red Cross infirmaries went to the Peninsula. The Balkan states attempted use the sympathy of the Russian society to put pressure on the official Petersburg. At first, the need to remake the Balkans was justified in various ways. And then the Bulgarians and Serbs tried to prove their case in the dispute over Macedonia. The book shows the methods by which this pressure was carried out, identifies foreign and Russian subjects who participated in this propaganda campaign. Descriptions of the Balkans and Balkan peoples interested Russian readers, and correspondents described in detail what they saw. The monograph reconstructs the existing image of Bulgaria and Serbia. On its basis, with the involvement of other sources and scientific literature, an attempt is made to restore the real picture of life in Bulgaria and Serbia on the eve of the First world war and its features, to understand the peculiarity of Westernization "in the Balkan way".

Authors: Tchinda Cedric F , Voukeng Igor K , Beng Veronique P , Kuete Victor
Published: November 2020

Background: The Cameroonian pharmacopoeia is full of many plants used amongst population to treat various infections. Albizia adianthifolia (Schum.) is one of these plants and therefore several previous studies have reported the antibacterial activities of the crude methanol extract of the roots of this plant as well as those of some of its isolated compounds. In this study, the methanol root extract, and its isolated compound "adianthifolioside GS1" were evaluated on bacterial growth kinetics, bacterial membrane, biofilms, and sheep erythrocytes. Adianthifolioside GS1 was tested for its antibiotic stimulation activity against multidrug resistant (MDR) Gram-negative bacteria. Methods: The antibacterial activities of adianthifolioside GS1 in combination with the usual antibiotics were evaluated using the modified p-iodonitrotetrazolium chloride (INT) rapid colorimetric test. Determination of the effect of "crude extract and adianthifolioside GS1" samples on bacterial growth kinetics, bacterial membrane, biofilms, and sheep erythrocytes was carried out using spectrophotometric methods. Results: In combination with erythromycin (ERY), gentamicin (GEN), streptomycin (STR) and tetracycline (TET), adianthifolioside GS1 showed the most significant synergistic effects on all bacteria tested. Adianthifolioside GS1 and the crude root extract of Albizia adianthifolia showed a bacteriostatic effect on the strains tested and caused membrane lysis in Klebsiella pneumoniae KP55 and Escherichia coli AG102 strains at the concentrations tested. Albizia adianthifolia root extract showed significant inhibition of the biofilms of the strains tested, unlike adianthifolioside GS1. The crude extract and its isolated compound (adianthifolioside GS1) exhibited low toxicity to red blood cells. Conclusion: All the results obtained in the framework provide important information on the crude root extract of Albizia adianthifolia and its isolated compound "adianthifolioside GS1" as good candidates for the elaboration of phytomedicines and drugs respectively, and the association of adianthifolioside GS1 with the usual antibiotics that can be used to potentiate the action of the latter. Keywords: Albizia adianthifolia; adianthifolioside GS1; Mechanisms of action; Fabaceae; multi-drug resistance; enteric bacteria.

Published: November 2020

Dalam pembelajaran Bahasa Indonesia, peserta didik dituntut agar bisa terampil menggunakan Bahasa Indonesia yang baik dan benar, karena seseorang yang terbiasa dan terus berlatih menggunakan bahasa Indonesia yang baik dan benar, memiliki kemungkinan yang besar untuk dapat beradaptasi terutama dalam hal komunikasi di manapun ia berada. Akan tetapi, kemampuan berbahasa Indonesia yang baik dan benar ini tidak dapat terjadi dengan sendirinya. Hal ini harus sejalan dengan kemampuan menulis, karena menulis adalah salah satu upaya yang dapat dilakukan agar seseorang mampu mengungkapkan isi pikirannya dalam bentuk ucapan dan perkataan yang sempurna. Menurut Siswartini (dalam Fitrianita, Syahrul, dan Tressyalina, 2017), Menulis adalah menyusun kata-kata menjadi kalimat yang benar sesuai dengan kaidah tata bahasa untuk menyampaikan pengetahuan atau menginformasikan suatu hal tentang suatu objek yang saling berhubungan. Oleh sebab itu, seseorang yang terampil dalam hal menulis, maka akan mudah baginya untuk mengungkapkan isi pikiran dan gagasannya kepada orang lain baik itu berupa fakta, opini, pengamatan, pengalaman terhadap suatu hal.
The terminal deoxynucleotidyl transferase (TdT, or DNTT) is differentially expressed in brain metastatic tissues of patients with metastatic breast cancer.
Authors: Mamoor Shahan
Published: November 2020

Metastasis to the brain is a serious complication of breast cancer (1-3) with limited treatment options (4, 5). We mined published microarray data (6, 7) to discover genes associated with brain metastasis in human breast cancer, and identified differential expression of the gene encoding the terminal deoxynucleotidyl transferase TdT, also known as DNTT, when comparing brain metastatic tissues to primary tumors of the breast. DNTT was expressed at significantly lower levels in metastasis to the brain as compared to primary tumors, and primary tumor expression of DNTT significantly correlated with relapse-free survival. We recently reported that the immunoglobulin light chain kappa constant locus, IGKC, was differentially expressed in the brain metastases of patients with metastatic breast cancer (8). These data indicate that the expression of an immunoglobulin gene segment as well as a critical part of the cellular machinery utilized in expression of rearranged immunoglobulin genes with complete diversity of the immunoglobulin repertoire is differentially expressed and down-regulated in brain metastatic breast cancer, suggesting limiting immunoglobulin repertoire diversity is important for metastasis to the brain.

Infants' Sleep Onset Crying: Learned Behavior or Evolutionary Adaptation
Authors: Hasanov Eldar T.
Published: November 2020

Why do infants persistently cry when they drift off to sleep? Is sleep onset crying a learnedbehavior or evolutionary adaptation? Are there any evolutionary advantages behind thisbehavior? At some point in evolutionary history, the ancestors of humans left the trees andstarted terrestrial way of life. Along with many benefits that allowed hominins to eventuallybecome modern humans, this transition made early humans more vulnerable to predation andother dangers associated with the tree-to-ground transition. The risks were particularly high forinfants and young children, because unlike many other animals they are not self-reliant for along time after their birth. Driven by evolutionary pressure, infants’ sleep onset crying evolved toraise their survival probability by ensuring that their caregivers are in close proximity when theyare asleep. This trait became heritable and prevalent as a result of natural selection for itscapacity to repeatedly prevent threatening events after the tree-to-ground transition. Alternativebehaviorist explanations argue that behavioral insomnia in childhood is a learned behavior thatshould be extinguished by various “cry-it-out” techniques. However, if this behavior is notacquired but genetically programmed, then according to attachment theory the attempts toobstruct it may have long-term negative effects on mechanisms of social bonding.

Factsheet: The impact of the nationwide COVID-19 lockdown on adult New Zealanders' experiences of unwanted digital communications
Authors: Melhuish Neil , Pacheco Edgar
Published: November 2020

In December 2019 an infectious coronavirus disease, commonly known as COVID-19, was identified in Wuhan, China. The disease spread rapidly and became a global pandemic. New Zealand’s first COVID-19 case was confirmed on 28 February 2020, after which the number of cases began to rise significantly, prompting the New Zealand Government to introduce a nationwide lockdown on 25 March 2020. This factsheet reports early findings from a quantitative study with adult New Zealanders. It explores how prevalent the experiences of unwanted digital communication were in the last 12 months, before, during, and just after the nationwide COVID 19 lockdown. This study found a higher prevalence of unwanted digital communications around the time of the nationwide lockdown. This study’s findings suggest that unexpected health and social events, such as the COVID-19 pandemic and compulsory lockdown, are factors that can trigger changes in people’s experiences of online risk from unwanted digital communications.

Authors: Veronice  , Helmi  , Henmaidi  , Arif Ernita
Published: November 2020

Knowledge Management (KM) in agriculture is an establishing system for creating, documenting, classifying, and disseminating knowledge, required for synergy of the development of technological innovation dissemination. KM framework requires assessment as a basis for the KM system in agricultural areas as efforts to determine the effectiveness of the system need to have a KM index which serves to represent conditions in the field. This study aims to determine the framework and KM index of small farmers in agricultural areas. Also, evaluating it as a basis for KM systems requires framework assessment in agricultural areas; therefore, the effectivity determination requires a KM index which represents the conditions in the field. The design process uses a Delphi method through the stages, as well as in-depth interviews with 15 experts, observations, and Focus Group Discussion. The result reveals the form of KM index measurement variables within agricultural areas. First, acquisition with indicators of all group member participation in all related activities. This process occurred within and outside the organisation, using a systematic approach. Second, storage with signs of knowledge access owned by all members, which are easily traceable and digitally stored, as well as the existence of information security mechanism. Third, distribution with indicators source, material clarity, and the delivery methods used. And fourth, application with indicators of precise regulation, utilising information technology. The average index results based on the reference of American Productivity and Quality Center (APQC)'s level of Knowledge Management Maturity KM obtained level 3 which is standardisation with the dominant indicator being the acquisition indicator. This study concludes the KM framework in the agricultural area has four variables, and the km level index is at level 3.

Breast cancer patients diagnosed with metastasis to the brain (1-3) are presented limited treatment options (4, 5). We mined published microarray data (6, 7) to discover genes associated with brain metastasis in human breast cancer, and identified differential expression of the gene encoding asporin, ASPN, when comparing brain metastatic tissues to primary tumors of the breast. ASPN was expressed at significantly lower levels in metastasis to the brain as compared to primary tumors, and primary tumor expression of ASPN was significantly correlated with overall survival (8). Asporin (9) , its ability to interact with TGF-β (10) and type I collagen (11), and inhibition of these interactions through down-regulation of asporin expression may be relevant to pathways underlying metastasis to the brain in human breast cancer.

Children are more exploratory and learn more than adults in an approach-avoid task
Authors: Liquin Emily , gopnik alison
Published: November 2020

Intuitively, children appear to be more exploratory than adults, and this exploration seems to help children learn, but there have been few clear tests of this idea. We test whether exploration and learning change across development using a task that presents a “learning trap.” In this task, exploitation—maximizing immediate reward and avoiding costs—may lead the learner to draw incorrect conclusions, while exploration may lead to better learning but be more costly. In Studies 1, 2, and 3 we find that preschoolers and school-aged children explore more than adults and learn the true structure of the environment better. Study 3 also demonstrates that children explore more than adults even though their predictions about the effects of exploration are similar to those of adults and they predict that exploration will be costly. It also shows that exploration and learning are correlated. Study 4 shows that children’s and adults’ learning depends on the evidence they generate during exploration: children exposed to adult-like evidence learned like adults, and adults exposed to child-like evidence learned like children. Together, these studies support the idea that children may be more exploratory than adults, and this increased exploration influences learning.
No Associations in Preregistered Study of Youth Depression and Functional Connectivity of Fronto-parietal and Default Mode Networks
Authors: Qu Yueyue , Rappaport Brent I , Luby Joan , Barch Deanna
Published: November 2020

Adolescence is characterized by vulnerability to the onset of major depressive disorder (MDD). The goal of this preregistered study was to assess neural correlates of depression symptoms in young adolescents, both cross-sectionally and longitudinally. The default mode network (DMN) is believed to support internal attention towards self-referential thoughts, while the fronto-parietal network (FPN) is theorized to support cognitive control and regulation of attention. As MDD diagnosis has been associated with heightened connectivity within DMN regions and diminished connectivity within FPN regions relative to healthy controls, our study builds upon group-difference analyses by using dimensional measures of depression severity. Our preregistered hypotheses were that within-DMN functional connectivity would be positively associated with concurrent depression severity, while within-FPN functional connectivity would be negatively associated with concurrent depression severity. Preregistered analyses also examined between DMN-FPN connectivity as an alternative predictor variable, and assessed the longitudinal associations between all three functional connectivity measures and change in depression severity over three subsequent waves. Multiple regression models tested cross-sectional analyses and hierarchical linear models tested longitudinal analyses. One hundred and twenty-four youth completed a resting state functional MRI. Their depression severity was assessed at the time of the scan and at three follow-up sessions. None of the predictor variables were associated with concurrent or depression severity, nor with the slope of depression symptom trajectories in longitudinal analyses. These negative results add to extant cross-sectional studies, and may inform future investigations of brain correlates of depression psychopathology in youth.
Illusory essences: A bias holding back theorizing in psychological science
Authors: Brick Cameron , Hood Bruce , Ekroll Vebjørn , de-Wit Lee
Published: November 2020

The reliance in psychology on verbal definitions means that psychological research is unusually moored to how humans think and communicate about categories. Psychological concepts (e.g., intelligence; attention) are easily assumed to represent objective, definable categories with an underlying essence. Like the 'vital forces' previously thought to animate life, these assumed essences can create an illusion of understanding. We describe a pervasive tendency across psychological science to assume that essences explain phenomena by synthesizing a wide range of research lines from cognitive, clinical, and biological psychology and neuroscience. Labeling a complex phenomenon can appear as theoretical progress before sufficient evidence that the described category has a definable essence or known boundary conditions. Category labels can further undermine progress by masking contingent and contextual relationships and obscuring the need to specify mechanisms. Finally, we highlight examples of promising methods that circumvent the lure of essences and we suggest four concrete strategies to identify and avoid essentialist intuitions in theory development.
Visual convex time preferences: Lab, field and high schools
Authors: Branas-Garza Pablo , Prissé Benjamin
Published: November 2020

The original standard for measuring time preferences was Multiple Price List (MPL), where subjects are asked to choose between an amount of money in the present and a larger amount of money in the future. Convex Time Budget (CTB) was later introduced, allowing subjects to differentiallyallocate money between present and future. It improved precision of measurement but also increased the complexity of the task. In this paper we introduce the Visual Convex Time Preferences (VCTP), a new measure of time preferences synthesizing simplicity of MPL and precision of CTB. Results from the lab suggest that VCTP is robust and improves precision of time preferences measurement compared to the MPL. Same results are replicated in the field of Honduras, especially when the experiment is run with the help of enumerators. Experiments with teenagers show that younger population exhibit high level of inconsistency although older participants perform better.
Decomposing conditioned avoidance performance with computational models
Authors: Krypotos Angelos-Miltiadis , Crombez Geert , Meulders Ann , Claes Nathalie , Vlaeyen Johan
Published: November 2020

Avoidance towards innocuous stimuli is a key characteristic across anxiety-related disorders and chronic pain. Insights into the relevant learning processes of avoidance are often gained via laboratory procedures, where individuals learn to avoid stimuli or movements that have been previously associated with an aversive stimulus. Typically, statistical analyses of data gathered with conditioned avoidance procedures include frequency data, for example, the number of times a participant has avoided an aversive stimulus. Here, we argue that further insights into the underlying processes of avoidance behavior could be unraveled using computational models of behavior. We then demonstrate how computational models could be used by reanalysing a previously published avoidance data set and interpreting the key findings. We conclude our article by listing some challenges in the direct application of computational modeling to avoidance data sets.

Published: November 2020

Mutual aid groups have flourished during the Covid-19 pandemic. However, a major challenge is sustaining such groups, which tend to decline following the initial upsurge immediately after emergencies. The present study investigates one possible motivation for continued participation: the wellbeing benefits associated with psychological membership of groups, as suggested by the ‘social cure’ approach. Interviews were conducted with 11 volunteers in a mutual aid group organised by ACORN, a community union and anti-poverty campaigning organisation. Through qualitative analysis we show that participation provided wellbeing in different ways: positive emotional experiences, increased engagement in life, improved social relationships, and greater sense of control. Participants also reported some negative emotional experiences. Whilst all interviewees experienced benefits from participation, those who viewed their participation through a political lens were able to experience additional benefits such as feelings of empowerment. Moreover, the benefits conferred by a shared political identity appeared to be qualitatively different from the benefits conferred by other forms of shared identity. The interview data is used to hypothesise an overall process by which participants may come to attain a political identity via mutual aid. These findings have implications for how such groups retain their members and how authorities support these groups.
Some Simulation Results and Parameter Analyses of a Generalized Quasi Two-Phase Bulk Mixture Model
Authors: Khattri Khim B. , Kattel Parameshwari , Tuladhar Bhadra Man
Published: November 2020

Here, we consider a newly constructed generalized quasi two-phase bulk model for a rapid flow of a debris mixture consisting of viscous fluid and solid particles down a channel. The model is a set of coupled partial differential equations with new mechanical description of generalized bulk and shear viscosities, pressure, velocities and effective friction. The dynamical variables, physical parameters, inertial and dynamical coeffcients and drift factors involved in the equations contain certain important physics of mixture flow. So, we analyze the behaviour of some inertial and dynamical coeffcients involved in the model. These coeffcients strongly depend upon the initial material composition. We also simulate the evolution of the dynamical variables so as to reveal their strong non-linear behaviours. Through simulations, we also analyze the front position of the debris material, bottom-slip velocity and maximum velocity, which show fundamentally different dynamics for varied material compositions, from dilute to dense flows. Generalized mixture viscosity decreases as the ow moves downslope, and the rate at which it decreases depends upon the initial solid-volume fraction. We also compare the effective viscosity and the bulk mixture viscosity with respect to the norm of the strain rate tensors to reveal different non-linear behaviours.

Published: November 2020

In the present work, subordination results for function f(z)γ belonging to a new class of analytic function Snγ (α, β, j) defined using the concept of Hadamard product are obtained. Also coeffcient estimates, growth and distortion properties for function f(z)γ in the class RSnγ (α, β, j) of Bessel type are equally investigated.

Determination of Phase-Eigenvalues by Rational Factorization and Enhanced Simulation of Two-Phase Mass Flow
Authors: Pokhrel Puskar R. , Tuladhar Bhadra Man
Published: November 2020

In this paper, we present simple and exact eigenvalues for both the solid- and fluid-phases of the real two-phase general model developed by Pudasaini (2012); we call these phase-eigenvalues, the solid- phase-eigenvalues and the fluid-phase-eigenvalues. Results are compared by applying the derived phase- eigenvalues that incorporate the phase-interactions in the two-phase debris movements against the simple and classical solid and fluid eigenvalues without any phase interaction. We have constructed several different set of eigenvalues including the coupled phase eigenvalues by using rational factorization method. At first, we consider for general debris height; factorizing the solid and fluid lateral pressure contributions by considering the negligible pressure gradient; negligible solid lateral pressure; negligible fluid lateral pressure; negligible solid and fluid lateral pressure. Secondly, for a thin debris ow height, we also construct the fourth set of eigenvalues in three different cases. These phase-eigenvalues incorporate strong interaction between the solid and fluid dynamics. The simulation results are produced by taking all these different sets of coupled phase-eigenvalues and are compared with the classical uncoupled set of solid and fluid eigenvalues. The results indicate the importance of phase-eigenvalues and supports for a complete description of the phase- eigenvalues for the enhanced description of real two-phase debris flows and landslide motions.

A New Postulate and Some Conjectures Concerning Pair Primes in the Interval [n!, (n + k)!]
Authors: Adeyemi Abiodun E.
Published: November 2020

This paper rather studies the behaviour of prime numbers bounded below and above by positive integers n! and (n + k)!, and then after some numerical evidence, postulates that there is at least one pair primes of gap k ∈ 2Z+ in between n! and (n + k)! for every integer n ≥ 2 and every even integer k > 0. This assertion would eventually provide another structural form for Euclid theorem of ifinitude of primes, a kind of projection of the form in the original Bertrand postulate (now Chebychev's theorem). The truth- fulness of the conjecture that emanated from this postulate implies the Polignac's conjecture which aptly generalizes the twin prime conjecture. We thus present the new postulate and the conjectures for future research.

Fossilized stems are records of an exuberant Permian forest distributed in the State of Tocantins. Studies on the origin of fossilization are still lacking. The work aims to understand fossilization by describing crystalline textures present in preserved plant tissues. Macroscopic descriptions of morphoanatomical elements allowed the systematic classification of 6 specimens of stems of the genus Psaronius. Microscopic descriptions (binocular loupe and petrographic microscope) revealed the preservation of morphoanatomy by crystalline silica textures (quartz and chalcedony). This mineralogy indicates permineralization by silica as the fossilization process. Keywords: fossilized stems, Psaronius, permineralization, Permi
THE PHASE ADDITION METHOD TO EVALUATE RIETVELD MINERAL QUANTITATIVE ANALYSIS OF HYDRATED CEMENTS

X-ray powder diffraction (XRPD) analysis combined with the Rietveld method is commonly used in the mineralogical quantification of a range of different samples, including soil, rocks, and many industrial materials. The combination of this technique with the addition method, i.e. the successive addition of a mineral phase to the investigated sample, offers a simple and reliable method to test Rietveld results without the need for third techniques. Four different hydrated cement samples were successive mixed (at 1, 5, and 10%) with one of the main mineral-related phases (ettringite, larnite, ternesite, or ye’elimite) occurring in them. The Rietveld quantified amounts of these phases show a very good agreement with their added amounts, all resulting in regression lines with R2>0.99. The respective line equations permitted the calibration of the quantified amounts of the studied mineral phases, which presented standard deviations lower than 0.3. Keywords: Rietveld; addition method; hydrated cement, calcium sulphoaluminate.
