A Video-Based Method to Quantify Stroke Synchronisation in Crew Boat Sprint Kayaking
Authors: Tay Cheryl Sihui , Kong Pui Wah
Published: January 2019

The study aimed to quantify stroke synchronisation in two-seater crew boat sprint kayaking (K2) using a video-based method, and to assess the intra- and inter-rater reliabilities of this method. Twelve sub-elite sprint kayakers (six males and six females) from a national team were paired into six single-gender K2 crews. The crews were recorded at 120 Hz with a sagittal-view video camera during 200-m time trials. Video analysis identified four meaningful positions of a stroke (catch, immersion, extraction and release). The timing difference (termed “offset”) between the front and back paddlers, within each K2, at each stroke position was calculated, with zero offset indicating perfect synchronisation. Results showed almost perfect intra-rater reliability of this method. The intra-class correlation (ICC) ranged from .87 to 1.00, and standard error of measurement ( SEM) from 0 to 5 milliseconds (ms). Inter-rater reliability was substantial to almost perfect (ICC .72 – .94, SEM 2 – 6 ms). On average, 35 strokes were analysed for each crew and the mean offset was 17 ms, or 5.7% of water phase duration. Crews were more synchronised at the catch (11 ms, 3.8%) than the release (21 ms, 7.2%). However, the stroke synchronisation profiles of the six sub-elite crews varied considerably from each other. For example, the best performing male and female crews had directly contrasting profiles. This suggests that there is no universal stroke synchronisation profile for well-trained sprint kayakers. This video-based method may aid future investigations on improving performance.
Cognitive Scripts, Anxiety and Styles of Coping with Stress in Teenagers Practising Sports
Authors: Basiaga-Pasternak Joanna
Published: January 2019

The aim of the study was to present the relationships between the way of perceiving oneself and the world by young athletes, the cognitive anxiety and the ways of coping with stress. The target group consisted of 222 participants (114 boys and 108 girls) aged 16–20, students of sports-profiled secondary schools. The participants specialised in both winter and summer sports, as well as in individual and team sport disciplines. The following tools were implemented: Attitudes to Intrapersonal, Interpersonal and to the World Questionnaire, Coping Inventory for Stressful Situations (CISS) and Sport Anxiety Scale. The study showed that negative perception of oneself and others increases the level of cognitive anxiety and decreases the tendencies to search for social contacts in the face of stress. With regard to the positive image of oneself and others, the opposite was observed. The above relationships refer mainly to girls who practise sports.

The purpose of this study was to examine relations among reinvestment, self-regulation, and perception of choking under pressure in skilled tennis players. Participants were 160 collegiate players from the NCAA Division I in the U.S. and the 1st League in Japan. Participants completed questionnaires assessing reinvestment (conscious motor processing and movement self-consciousness), self-regulation, and perception of choking under pressure. Results of correlation analysis indicated self-regulatory factors were positively related to reinvestment conscious motor processing, but not with reinvestment movement self-consciousness. Self-efficacy and movement self-consciousness of reinvestment were found to predict one’s perception of choking under pressure. Results of simultaneous entry multiple regression revealed that tennis players who had low self-efficacy and were concerned about making a good impression with their movements were more likely to perceive that they choked during tennis matches. Additionally, Japanese players reported less self-regulation skills and a higher perception of choking under pressure than American players, suggesting the need for additional research on cross-cultural differences. Overall, these results suggest that self-efficacy may protect athletes from choking, but movement self-consciousness may lead athletes to choke during tennis games.

Published: January 2019

The study compares the effect of an exercise-based cardiac rehabilitation program with a program combining physical exercise and lower extremity neuromuscular electrical stimulation (NMES) on the recovery of patients with chronic heart failure (CHF) with NYHA II-III symptoms. Seventy two patients with stable CHF were randomly distributed to four groups that received exercise-based cardiac rehabilitation and pharmacological treatment. Groups I and II were additionally administered NMES (35 Hz and 10 Hz, respectively) and in Group III sham NMES was applied. Group IV (controls) received solely pharmacological and exercise treatment. Exercise tolerance and quality of life were assessed in patients pre-treatment and at week 3. Three weeks of rehabilitation induced significant increases (p < 0.05) in the distance covered in the 6-minute walk test, the metabolic equivalent (MET), the duration of the treadmill exercise stress test, the left ventricle ejection fraction (LVEF) and improved quality of life in all groups, but between-group differences were not significant (p > 0.05). In none of the groups were the left ventricle end-systolic and end-diastolic diameters (mm) measured at week 3 significantly different from their baseline values (p > 0.05). Exercise-based cardiac rehabilitation contributed to higher exercise tolerance, LVEF and quality of life of CHF patients (NYHA II-III), contrary to cardiac rehabilitation combined with lower extremity NMES (35 Hz and 10 Hz) that failed to induce such improvements. More research is necessary to assess the therapeutic efficacy of NMES applied to CHF patients with NYHA IV symptoms.
Parameters of the Transition from a Cultural to a Political Program by the Czech and Slovak Elites in the Mid-19th Century
Authors: Doubek Vratislav
Published: January 2019

This article examines the rise of the nascent intellectual and business bourgeois elites of the Czechs and Slovaks, focusing on the transformation of their cultural program into a political one. The article takes a comparative approach and investigates the relationship of political programs to prepolitical identities, zooming in on the parameters of a broader Czech and Slovak state identity, including the role of the center (Vienna, Pest, Prague, or Pressburg) or language (analyzing both its unifying and divisive roles in bridging the ideas and visions of the emerging local elites). As I argue, in the case of the Czech and Slovak nationalist movements, we can observe a transition from a prepolitical to the political program in the mid-19th century itself.
Prospek Penelitian Artefak Perunggu Temuan Kerinci Melalui Analisis Metalurgi
Authors: Sunliensyar Hafiful Hadi
Published: January 2019

Temuan artefak perunggu dalam se-abad terakhir di dataran Kerinci diteliti hanya sebatas pada kajian deskripsi dan ikonografi semata. Seringkali data yang didapat belum begitu akurat untuk merekonstruksi budaya masyarakatnya pada masa lampau. Apalagi temuan-temuan tersebut tidak kontekstual lagi. Analisis metalurgi yang telah banyak dilakukan peneliti terhadap temuan artefak perunggu di tempat lain, memberi kesempatan untuk ‘membongkar’ kembali artefak perunggu Kerinci agar dilakukan kajian melalui analisis metalurgi dengan studi komparatif. Melalui pendekatan induktif dalam tulisan ini, penulis mencoba memberikan gambaran tentang prospek penelitian artefak perunggu Kerinci melalui analisis metalurgi. Beberapa prospek penelitian ke depan antara lain: (1) aspek teknis pembuatan artefak tersebut; (2) aspek sosial-ekonomi seperti penelitian jalur perdagangan kuna ke Kerinci pada masa klasik; (3) migrasi artefak atau ideofak mengenai teknologi pembuatan perunggu dari Dongson ke wilayah Kerinci; (4) penelitian mengenai permasalahan apakah artefak perunggu Kerinci diimpor atau diproduksi  secara lokal.
Albite thermal barrier and alkaline granite-syenitenepheline-syenite rock association (series, formation, assemblage)
Authors: Dubrovsky Mikhail I.
Published: January 2019

The object of research.The main goal of the work was to resolve the problem of the existence of rock associations: alkaline granites–syenites–nepheline syenites, which is found on all continents among ancient platforms and stabilized folded regions of different ages. Beginning with 70-th. of the past century, the absolute majority of the world's petrologists do not allow the possibility of a comagmatic formation of such a rock association due to the presence of a thermal albite “barrier” between phonolitic and rhyolitic melts.Materials and methods. Numerous data were used on the Ilimaussak alkaline massif from southern Greenland as the most thoroughly studied and widely known to petrologists around the world. The main methods of research were the development of physicochemical models of phase transitions and the construction of state diagrams.Results.Earlier, thanks to the author's work in the field of constructing state diagrams, the possibility of “destruction of thermal barriers” was demonstrated at the appearance of alumosilicate melts of biotite, amphibole, analcime and other minerals on the liquidus. The developed physicochemical models of phase transitions for specific rock associations of the Ilimaussak massif allowed us to prove the possibility of a comagmatic transition from nepheline-modal syenites to quartz-modal alkaline granites.Conclusions.The validity (correctness) of the theoretical constructs is proved by an almost perfect coincidence of the model and natural trends of the rock associations. This requires a certain composition of the initial melt and the optimal fluid pressure.
Mineralogical and petrographic features of metakomatiites of the Kostomuksha greenstone structure (Karelia)
Authors: Klimovskaya Ekaterina E. , Ivanov Andrei A.
Published: January 2019

Object of study. The paper presents the mineralogical and petrographic study results of metamorphosed and metasomatized komatiites and komatiitic peridotites from the Ozerki soapstone deposit and Pentinsuo prospect, located in the Kostomuksha greenstone structure of the Karelian Craton, Fennoscandian Shield. Material and methods. Surface and drill core samples of various mineral and structural-textural varieties of altered komatiites were studied by optical microscopy, electron microscopy with an attachment for microanalysis, XRD phase, thermogravimetric and chemical analysis. Results. Soapstone formation in the investigated localities displays a multistage alteration and associates with the superimposed alteration of Mg-rich metakomatiite flows and olivine cumulates due to influx of carbon dioxide bearing fluids enriched in calcium and potassium. The chemical composition of initial komatiite (MgO content of the rock) and the degree of its fracture intensity are the main factors controlling soapstone formation. In differentiated lava flows soapstone is formed mainly in high-magnesium cumulate zones characterized by a high content of serpentine. In the flow top and spinifex zones an early amphibole-chlorite-magnetite mineral association is preserved in varying degrees. Talc and carbonate are formed by the decomposition of serpentine and amphibole. The chlorite content in soapstone is controlled by the Al2O3 concentration in the respective flow zones. Conclusion. The carbonate-chlorite-talc is the general natural type of soapstone associated with thin komatiite lava flows of distal volcanic facies. In more thick proximal lava flows the formation of soapstone of chloritecarbonate-talc and talc-carbonate composition is possible. The most prefered prospecting areas for soapstone are fields proximal to the eruptive vent, main lava conduits and subvolcanic analogues of komatiites.
Au-Ag-Pd-Pt mineralization in sedimentary rocks associated with Triassic carbonaceous silicites of Sikhote-Alin
Authors: Kazachenko Valentin T. , Perevoznikova Elena V.
Published: January 2019

Subject.The paper is devoted to the study of the gold-silver-palladium-platinum mineralization of the streaky systems in the sedimentary rocks associated within the Triassic carbonaceous silicites of the Taukhinsky and Samarkinsky terranes of the Sikhote-Alin.Materials and methods.In the process of investigations we studied the metamorphosed carbonaceous siliceous-clay rocks and systems of the mineralized fractures in the Triassic siliceous-clay and siliceous (including jaspers) rocks of Shirokopadninskaya, Vysokogorskaya and Gornaya areas, as well as in the sandstones (unclarified age) of Gornaya area. The samples for the analytical study were taken with the lump way. To estimate the content of precious metals in the rocks, cut by the systems of the mineralized fractures, we used the fire assay and atomic-absorption methods. The analyses of minerals (in polished sections) have been done using the JXA-5A and JXA8100 microanalysers.Results.The gold-silver-palladium-platinum mineralization in the siliceous and clay-siliceous rocks, as well as in the sandstones is restricted to the systems of the mineralized fractures and by many features are analogous to the precious-metal mineralization of the black-shale formations. It is represented by native forms, disordered solid solutions, and intermetallic compounds of different metals. The specificity of the Au-Ag-Pd-Pt mineralization is a wide distribution of copper gold, Ni-, Cu-, and Pbbearing gold, and Zn-bearing platinum. Native elements and intermetallic compounds, including those of precious metals, are not rarely associated with the organic matter testifying to the active participation of carbon and, probably, hydrogen that provided the high- and ultra-reduction character of the processes of mineral formation.Conclusions.The presence of the mineral forms of different maximum reduced metals is caused by the influence of the organic matter of the Triassic carbonaceous silicites. This consisted in the removal of the most volatile components, and first of all the poorly bound water and hydrocarbons from the carbonaceous rocks through the contact metamorphism related with the injection of the granitoid intrusions of Cretaceous plutonic and volcanoplutonic belts.

Published: January 2019

Object.Multi-proxy analysis of 265 cm long sediments core of Lake Turgoyak, one of the deepest lakes of the Southern Urals, is presented.Materials and methods.The lake ecosystem changes was reconstructed based on diatom, radiocarbon dating and geochemical analysis. Statistical treatment of the surface sediments composition and hydrochemistry data of 56 lakes from Southern and Middle Urals lakes database allowed to obtain geochemical indexes for reconstruction of water parameters: index of organic matter content (ОМ = LOI550ºС/(Al2O3 + TiO2 + Na2O + K2O)) and index of salinity (ММ = LOI950ºC/LOI550ºС). Results. Radiocarbon dating shows that sedimentation in Lake Turgoyak was began more than 12 cal kyr BP ago. Each of six lithological units of sediments core is characterized by its own geochemical features and associated with global (11.8, 11.2, 8.2 cal kyr BP) and regional (12, 10.3 cal kyr BP) climate events of the Northern Hemisphere. Four main stages of Lake ecosystem development were identified: 1) the beginning of lake sedimentation (>12.1 cal kyr BP); 2) the stage of a subsaline shallow-water lake (12.1–11.2 cal kyr BP); 3) the stage of a freshwater lake with increased water-level (11.2–8.0 cal kyr BP); 4) the stage of water organic matter increase (<8.0 cal kyr BP).Conclusions.High content of mesohalobic diatoms and salinity module values showed significant increase of lake water salinity as response to Early Holocene climate warming (11.8–11.2 cal kyr BP). Pantle-Buck’s Saprobity Index and OM values pointed to the lake water organic matter increase due to the next climate warming since 9–8 cal kyr BP. Thus, Lake Turgoyak water parameters were reapeatedly changed during the Holocene. However the response of lake ecosystem was different in different periods of its development.
Imagem, consumo e presença
Authors: Arraes Marcos Alexandre
Published: January 2019

O artigo parte das reflexões de Hans Ulrich Gumbrecht a respeito das Materialidades da Comunicação para propor uma análise da emergência de um regime visual e novas políticas de consumo nos anos 1950 e 1960 no Brasil pautado em um paradigma cultural estadunidense. O texto insere-se em uma perspectiva de Estudos Visuais e procura demonstrar que a profusão de imagens no período em questão, longe de produzir uma “perda do mundo hermeneuticamente induzida”, é produtora de presença. Em outras palavras, para proporcionar uma análise histórica específica, buscar-se-á compreender como a linguagem imagética, para além de ser um domínio exclusivo da cultura de sentido, como pretendem alguns, produz efeitos estéticos tangíveis aos corpos, e, portanto, produz presença.

En las disímiles variaciones de esa faena imperial de la razón actuante como lo es el acto educativo, aquella que se ocupa del hallazgo y enriquecimiento de la Sensibilidad Civilizatoria, a través de su ejercicio instructivo/orientador, nos enfrenta a no pocas encrucijadas de compleja descripción.No pretendo significar en esta ocasión, los intrincados nudos de esta praxis que ya he ubicado en términos de “práctica pedagógica confrontada” , sino de reiterar cómo el camino hacia una intención epistemológica de la formación artística en nuestro contexto, nos obliga a la par de la búsqueda de metodologías o preceptos, a priorizar cual es el sentido y finalidad de la formación artística en atención al encargo educativo. Para este peculiar orden de reconocimiento de la conciencia y capacidad práctica del hombre que lo compulsa en los afanes hacia el triunfo de sus íntimas y públicas glorias, resulta de justa estimación esa inteligencia americana, siempre franqueadora ante muy diversas disyuntivas, ya advertidas por Alfonso Reyes.
Formalismo, Abstracción, rigor y dificultad en la matemática
Authors: Gutiérrez Hoyos Hernando
Published: January 2019

He aquí cuatro términos que usualmente se confunden como sinónimos cuando se intenta hacer una caracterización de la matemática por parte de personas no especializadas en esta disciplina. La confusión llega a presentarse, incluso, entre personas que han recibido algún tipo de formación matemática pues no es raro encontrarse divulgadores de la materia que no establezcan claramente las diferencias y relaciones que existen entre estos términos.Quienes han tenido oportunidad de acercarse a la matemática indagando sobre la naturaleza de sus conceptos y la estructuración del conocimiento matemático, por encima de la simple manipulación de los procesos operativos asociados y/o derivados de estos conceptos, saben que existen relaciones pero también diferencias entre los cuatro términos del enunciado que contribuyen, precisamente, a la configuración unitaria de la diversidad que es, muy seguramente, una de las características esenciales de la matemática.Con el fin de estimular este acercamiento, que necesariamente debemos promover, a la matemática a través de conductas diferentes de la tradicional operatividad mecánica; voy a intentar presentar de una manera sencilla (ojalá la sencillez no desvirtúe los conceptos) cada uno de estos términos y aclarar las confusiones más frecuentes en la interpretación de ellos.

Pelarangan Buku di Indonesia era Orde Baru: Perspektif Panoptikon Michel Foucault
Authors: Iqbal Muhammad
Published: January 2019

Pelarangan buku adalah bentuk paradoks di negara demokrasi karena memperlihatkan kesewenangÂ­wenangan dalam membatasi kebebasan berpikir, berpendapat, dan berekspresi. Padahal semua itu dijamin oleh prinsipÂ­prinsip dasar demokrasi, bahkan secara tegas ditulis dalam UndangÂ­Undang Dasar 1945. Melarang buku juga menjadi paradoks bagi kehidupan bermedia di Indonesia yang lebih dari satu dekade terakhir telah mengumandangkan dukungan terhadap kebebasan pers. Pelarangan buku, di sisi lain, mengindikasikanÂ  ambiguitasÂ  kebijakan Â penguasa. AlihÂ­alih mengantisipasi polemik di masyarakat, lewat tindakan pelarangan buku, pemerintah memperlihatkan praktikÂ­praktik primitif dalam mengontrol, mengarahkan, membatasi, bahkan memandulkan cara berpikir masyarakat. Pelarangan buku juga mencerminkan ketakutan penguasa dengan mengekang hak politik warga negaranya, tidak mengakui adanya keanekaragaman perspektif dan sudut pandang. Artikel ini ingin meneroka sejarah kebijakan pelarangan buku oleh rezim Orde Baru (Orba), guna mencatat perubahan bentuk dan orientasi yang melatari tindakan pelarangan buku sesuai konteks zamannya, serta apa dampaknya terhadap pendisiplinan masyarakat Indonesia.

Analisa Potensi Geografis Timur Tengah Menjadi Kekuatan Teritori Melalui Komik Digital Berlandaskan Paradigma Pedagogi Reflektif telah menjawab tantangan era Revolusi Industri 4.0 menjadi peluang. Tujuan penelitian ini ialah 1)menganalisis potensi geografis Timur Tengah menjadi kekuatan teritori ; 2)menguraikan komik digital berlandaskan paradigma pedagogi reflektif. Metode yang digunakan adalah penelitian kualitatif yang menggambarkan tentang kegiatan atau informasi tentang kondisi kelas yang sedang berlangsung. Data penelitian dikumpulkan melalui observasi dengan teknik cuplikan yang dikenal dengan purposive sampling. Sampel yang digunakan adalah salah satu informan untuk mendapatkan informasi mengenai media yang tepat. Hasil penelitian menunjukan bahwa 1) Banyak pelopor nasionalisme Arab yang memiliki misi menyelamatkan bangsanya terbebas dari tradisi yang terlalu konservatif untuk tetap memajukan bangsa serta terbebas dari penetrasi asing diantaranya Sultan Abdul Hamid II(Turki), Al-Tahtawi (Mesir), MuhammadÂ  RashidÂ  Rida (Syria), Mustafa Kemal Ataturkh (Turki), Gammal Abdul Nasser (Mesir). Selain gagasan para nasionalis wilayah lain yang merasakan pengaruh asing yang kuat langsung bereaksi dengan membuat ketetapan netralitas dengan tidak memihak blok manapun yang memiliki kepentingan. Namun, ada pengecualian untuk Arab Saudi dimana AS tetap bekerjasama dalam bidang ekonomi dan terbukti dengan adanya perusahaan asing ARAMCO (Arabia American Company Oil) dan ini dirasa lebih menguntukan dari pada menempatkan pangkalan militer asing.; 2) Frekuensi mahasiswa yang menguraikan analisa potensi geografis Timur Tengah menjadi kekuatan teritori melalui komik digital berlandaskan paradigma pedagogi reflektif ialah sebesar 30% atau sekitar 15 dari jumlah keseleuruhan mahasiswa 50, sedangkan topik lain (tokoh, konflik ideologi, konflik kepentingan barat, konflik perbatasan) mendapatkan porsi rata-rata seitar 10-20%.

Authors: Burley Kalistyn H. , Gill Samuel C. , Lim Nathan M. , Mobley David
Published: January 2019

Molecular simulations are a valuable tool for studying biomolecular motions and thermodynamics. However, such motions can be slow compared to simulation timescales, yet critical. Specifically, adequate sampling of sidechain motions in protein binding pockets proves crucial for obtaining accurate estimates of ligand binding free energies from molecular simulations. The timescale of sidechain rotamer flips can range from a few ps to several hundred ns or longer, particularly in crowded environments like the interior of proteins. Here, we apply a mixed non-equilibrium candidate Monte Carlo (NCMC)/molecular dynamics (MD) method to enhance sampling of sidechain rotamers. The NCMC portion of our method applies a switching protocol wherein the steric and electrostatic interactions between target sidechain atoms and the surrounding environment are cycled off and then back on during the course of a move proposal. Between NCMC move proposals, simulation of the system continues via traditional molecular dynamics. Here, we first validate this approach on a simple, solvated valine-alanine dipeptide system and then apply it to a well-studied model ligand binding site in T4 lysozyme L99A. We compute the rate of rotamer transitions for a valine sidechain using our approach and compare it to that of traditional molecular dynamics simulations. Here, we show that our NCMC/MD method substantially enhances sidechain sampling, especially in systems where the torsional barrier to rotation is high (>10 kcal/mol). These barriers can be intrinsic torsional barriers or steric barriers imposed by the environment.Overall, this may provide a promising strategy to selectively improve sidechain sampling in molecular simulations.
Graph-based Genetic Algorithm and Generative Model/Monte Carlo Tree Search for the Exploration of Chemical Space
Authors: Jensen Jan H.
Published: January 2019

This paper presents a comparison of a graph-based genetic algorithm (GB-GA) and machine learning (ML) results for the optimisation of logP values with a constraint for synthetic accessibility and shows that GA is as good or better than the ML approaches for this particular property. The molecules found by GB-GA bear little resemblance to the molecules used to construct the initial mating pool, indicating that the GB-GA approach can traverse a relatively large distance in chemical space using relatively few (50) generations. The paper also introduces a new non-ML graph-based generative model (GB-GM) that can be parameterized using very small data sets and combined with a Monte Carlo tree search (MCTS) algorithm. The results are comparable to previously published results (Sci. Technol. Adv. Mater. 2017, 18, 972-976) using a recurrent neural network (RNN) generative model, while the GB-GM-based method is orders of magnitude faster. The MCTS results seem more dependent on the composition of the training set than the GA approach for this particular property. Our results suggest that the performance of new ML-based generative models should be compared to more traditional, and often simpler, approaches such a GA.

The decreased in average mass of heavy metals obtained in University of Ilorin were found to be 1145.75, 797.75, 219.625, 133.51, 58.25 and 23.125 mg/kg for Mn, Zn, Pb, Ni, Cu and Cd respectively. For Kwara State University, decrease in the following order; 778.5, 323.875, 259.375, 101.375, 34.375, and 4.625 mg/kg for Mn, Zn, Pb, Ni, Cu and Cd respectively were found. Generally, the heavy metal concentrations decreases in the following order Mn>Zn>Pb>Ni>Cu>Cd for all the three sites.
Making Better Decisions During Synthetic Route Design: Leveraging Prediction to Achieve Greenness-by-Design
Authors: Li Jun , Eastgate Martin
Published: January 2019

This paper expands our work predicting Process Mass Intensity (PMI), as a methodology for exploring the potential efficiency of proposed synthetic routes. In the present work, we integrate a method for predicting the PMI contributions of high complexity reagents, needed to enable certain transformations. We focus on ligands for metal catalyzed reactions - and develop an approach for predicting which ligands may function in CN couplings - as a proof of concept. We leverage this to enable the integration of the PMI contribution of the ligands into a predictions of a routes efficiency, enabling an understanding of the holistic impact of a route decision..

Published: January 2019

Covalent organic frameworks (COFs) consist of monomers arranged in predictable structures with emergent properties. However, improved crystallinity, porosity, and solution processability remain major challenges. To this end, colloidal COF nanoparticles are useful for mechanistic studies of nucleation and growth and enable advanced spectroscopy and solution processing of thin films. Here we present a general approach to synthesize imine-linked 2D COF nanoparticles and control their size by favoring imine polymerization while preventing the nucleation of new particles. The method yields uniform, crystalline, and high-surface-area particles and is applicable to several imine-linked COFs. In situ X-ray scattering experiments reveal the nucleation of amorphous polymers, which crystallize via imine exchange processes during and after particle growth, consistent with previous mechanistic studies of imine-linked COF powders. The separation of particle formation and growth processes offers control of particle size and may enable further improvements in crystallinity in the future.
Investigations into Sampling Approaches for Chemical Analysis of Latent Fingermark Residue
Authors: Dorakumbura Buddhika , Busetti Francesco , Lewis Simon W.
Published: January 2019

Compositional variation of latent fingermark deposits sampled from the same donor (intra-donor) poses considerable challenges for the investigation of the degradation of chemical composition. The work presented here investigates the best approach of sampling of latent fingermark residues within this context. Gas chromatography-mass spectrometry (GC-MS) was used to quantify the amount of squalene in fingermarks deposited on non-porous surfaces and used it as an indicator of the amount of non-polar material successfully extracted. It was found that the percentage difference of squalene between two deposits (from two hands) obtained at a given time without controlling the deposition pressure was in the range of 4-100%. This was reduced to 0-44% in the other three sampling approaches, where deposition pressure was controlled. Under controlled deposition pressure, the averages of percentage difference (n=9) for sebum-rich and natural deposits were 13% and 20% respectively. These results demonstrate the significant influence of fingermark sampling approach over data and offer possible sampling strategies that can be undertaken to overcome issues associated with intra-donor variation.

We propose to define logicality of a simple notion as necessary instantiation. (And then logicality of a complex notion as logicality of all simple notions occurring in it.)
Mathematical Concepts as Natural Kinds
Authors: Nagase Daniel Arvage
Published: January 2019

This paper presents an approach to mathematical terms similar to the approach developed by Kripke in order to deal with natural kind terms; in fact, I argue that mathematical terms are natural kind terms in the sense of Kripke. Thus, I suggest that, from a semantic perspective, such terms should be seen as primarily referring terms, and, from a metaphysical perspective, that good definitions of such terms should embody structural information about the exemplars from the kind in question.

Authors: Almeida Edgar Luis Bezerra de
Published: January 2019

O tema deste trabalho é a verdade de proposições matemáticas e seu objetivo é avaliar, no contexto aritmético, um dos elementos presentes em Freire (2018) e também considerado por Ramos e Freire nesta edição da Revista de Filosofia Moderna e Contemporânea: a fixação do valor de verdade de asserções aritméticas a partir de princípios diretivos que regem a prática da disciplina. O método de análise visa à elucidação da contribuição dos princípios diretivos para a fixação do modelo padrão da aritmética e considera três métricas distintas. A partir desses resultados a proposta fundada nos princípios diretivos é comparada com três abordagens alternativas, presentes na literatura especializada. O resultado dessa comparação é bastante favorável à abordagem formulada por Freire e Ramos nesta Revista.

Authors: Simioni João Paulo Delapasse , Guasselli Laurindo Antonio
Published: January 2019

Land use land cover modeling is extremely important to land planners, since it allows creating projects and scenarios with possible future threats to ecosystems. Thus, the aim of the present study was to apply the CA-Marvok model to simulate the land use and land cover for the year 2030 in the environmental protection area of the Banhado Grande (EPABG), Brazil. Thus, two images Landsat 5 TM and 8 OLI from 2007 and 2017 were classified. The CA-Markov model was applied through the Land Change Modeler (LCM) tool of the TerrSet software. The results show that the soybean class was the one that most grew between 2007 and 2017, going from 5,891 to 33,844 ha. The simulation shows that 45,375 ha of soybeans will be cultivated at EPABG by 2030, replacing mainly floodplain areas and wetlands. In view of the above, it is concluded that the simulation of land use land cover for 2030 showed that soybean cultivated area will correspond to approximately 33% of land use and land cover in EPABG. Therefore, it is recommended to create the EPABG management plan focused on the maintenance of the biodiversity and wetlands of the EPABG.
Features of the kinetics of mass transfer processes in the process of firing ceramic materials
Authors: Nedbailo O.M. , Chernyshyn O.G.
Published: January 2019

In article the technique of definition factors of carrying over weight of substance in the course of roasting ceramic materials which is based on exponent dependences of change mass bodies from time of its heating is offered.
The process of firing ceramic materials is associated with the transfer of heat and mass of matter. Therefore, for a more complete calculation of the heat treatment mode, it is necessary to know the conditions for the mass transfer in the product being calcined. The aim of the work is to determine the mass transfer coefficients of the substance in the process of firing ceramic materials.
The mass loss rate of the bound matter or the mass loss per unit time will be directly proportional to the average mass content of the body. On the other hand, the mass loss rate of the bound matter is numerically equal to the slope of the mass content kinetics curve.
Proposed in the work formulas can be applied when studying the process of mass transfer during firing of samples from different clays, as when firing clay samples of different diameters under the same conditions, they will differ in the mass content (mass loss rate of the bound substance) during heating and their final relative amount (mass content) of the lost mass will be the same.
