Crónica investigativa para gestionar residuos peligrosos en talleres mecánicos de Bogotá
Authors: Montes Rodríguez Johan Sebastián , Moyano Tovar Cristian Eduardo , Restrepo Ocampo Cristian Andrés , Fuentes Cortés Gelen Yivi , Luque Forero Adriana Carolina
Published: December 2023

El bajo conocimiento del adecuado manejo de los residuos peligrosos que son generados en los talleres de mantenimiento mecánico en la calle sexta de la ciudad de Bogotá contribuye en la contaminación de recursos naturales como el agua, el aire, el suelo, entre otros. Estos talleres deben contar, por normativa, con una gestión sobre estos residuos peligrosos en el que se contemple zonas impermeabilizadas que evite derrames o vertimientos en cuerpos de agua, un adecuado almacenamiento que impida emisiones al aire, contar con permisos y planes de contingencia y el Registro de Generadores de Desechos o Residuos Peligrosos (RESPEL) entre otros trámites requeridos para este sector.

Por lo anterior, cobra importancia plantear un plan de capacitación, dirigido a los dueños y trabajadores de los talleres, orientado a la sensibilización y búsqueda participativa de mejoras y soluciones para generar un adecuado manejo de los residuos peligrosos y con ello contribuir en el cuidado y conservación de los recursos naturales.

El plan de capacitación propuesto les orientará desde el autoaprendizaje a cómo evitar y/o minimizar impactos al medio ambiente, a partir de la sensibilización, reflexión y aporte de los mismos dueños y trabajadores, ideas que serán indispensables para que el proceso se lleve a cabo con éxito.

La lactancia materna es uno de los indicadores más importantes de desarrollo y crecimiento infantil puesto que permite optimizar el estado nutricional del bebé, fortalecer el sistema inmune, aumentar la producción de inmunoglobulinas e incrementar el desarrollo y funcionalidad de las estructuras orofaciales y oromotoras del neonato. Asimismo, favorece el desarrollo socio afectivo entre la diada madre e hijo. (1) (2), sin embargo, en la actualidad, esta práctica ha sufrido grandes cambios debido a factores sociales, culturales, socioeconómicos, individuales, laborales y familiares, que representan que en Latinoamérica el 51% de los niños no son alimentados con leche materna en su primera hora de vida.

Published: December 2023

El hombre se ha ubicado en la esfera del Ser Humano como una unidad de cuerpo y alma de la cual se predica la integralidad sujeta al tiempo y al espacio, diferenciada de los demás al estar dotado de conciencia, libertad, temperamento y carácter, por lo que este último puede ser moldeado a través de la educación, el deseo de cambio y la repetición de una acción. Objetivo: Examinar las políticas educativas gubernamentales en la difícil tarea que atraviesa el Ser. Métodos y materiales: El tipo de investigación desarrollada corresponde a la documental, que da sustento al estudio investigativo, se empleó una herramienta sistematizada que incluye información de autores y sus publicaciones, pertinentes para esta investigación. Resultados: La educación secundaria o universitaria adquirida de manera formal o informal tiene un fin determinado en cada país y gobierno. Por lo tanto, es necesario enfocar y centrar el Ser Humano como objeto e instrumento en la educación. Discusión: Para replantear el punto central de este escrito, encaminado a definir como direccionar la educación en el Posacuerdo, y después de tomar como premisa al Ser, antes que el Saber y el Tener. Conclusiones: Acorde al análisis realizado, el hombre es pluridimensional, entonces, es difícil encontrar un sistema educativo que cumpla en su totalidad con las expectativas de esa función integral; por lo tanto, el modelo educativo debería ser: Escuela a la medida según lo definido por Edouard Clepèrede en su teoría de la pedagogía funcional, en otros términos: a la medida de quien lo usa. Desde la perspectiva del capitalismo, se estima, que los conocimientos adquiridos no deben ser solo teoría, sino que alternar con la práctica. Referente a las competencias, se debe seguir trabajando sobre los modelos educativos En cuanto a las políticas, y considerando que la formación debe ser integral.
“Residual Meanings” and the Aesthetic of Intermediality in Pavel Saltzman’s Central Asia in the Middle Ages
Authors: Gizdatov Gazinur
Published: December 2023

This article analyses Central Asia in the Middle Ages, an unfinished novel by Pavel Saltzman (1939–1950), first published in 2018. In the novel, the aesthetic of film editing and the discursive “madeness” of the narrative used by the author, which refers both to the literature of German Romanticism and to Eastern historical and literary sources, transforms an example of artistic avant-garde into a fundamentally new work in terms of artistic features. According to the article, the literary game of the Gothic novel employed by the author gives Saltzman’s text the dynamics of a spectacular film text, which conceals several symbolic and associative meanings. These include the adventurous narrative itself, the medieval historical plot, the inevitable associative parallels with the tragic pages of the history of the twentieth century, and the philosophical and aesthetic comprehension of man and their place in the world in the spirit of the German Romantics and modern postmodernism simultaneously. The research methods in relation to this literary text rely on the semiotic theory of Yu. M. Lotman and B. A. Uspensky. The results of the study are determined both by the author’s approach and modern literary and cultural studies concepts of Aage A. Hanzen-Löve, I. S. Kukui, and O. D. Burenina-Petrova. The novel is analysed for the first time according to the directions of “residual” memory of the author’s text that are relevant to this work, primarily in intertextual connection with E. T. A. Hoffmann’s The Devil’s Elixirs, as well as according to the cinematic ways of expressing the narrative. The author proves that Saltzman’s text relies on the principle of compositional film editing, which brings it into the sociocultural discursive practice. Additionally, the article traces intertextual links between the two novels in the plot and thematic aspects, concluding that the text is original for modern literature and determining the prospects of its transfer in sociocultural practice.
An Uncompleted Machine-Building Giant in the Urals: Mobilisation Policy and Construction Practice
Authors: Dumchikov Aleksandr , Pimenova Kseniya
Published: December 2023

This article examines the Ural Plant of Chemical Engineering in Sverdlovsk as an example of unfinished industrial construction through the command economy formation, industry management structure, and city-planning activities development in the USSR during the first five-year plans. The authors refer to sources kept in the GARF, RGAE, GASO, TsDOOSO, and the Uralhimmashzavod History Museum and periodicals. They characterise the scale of unfinished industrial construction in the Urals during the first five-year plans, which predetermined the geography of the evacuation and the direction of future industrial and city-building development of the regional centres. The article describes the circumstances behind the emergence of the Ural Plant of Chemical Engineering in the first five-year plan programme and its construction process. The authors single out three periods of the plant’s construction, which correspond to the waves of mobilisation of the project discourse: 1930–1933, 1934–1935, and 1938–1941. They explain the causes of failure by the late emergence of the Uralhimmashstroi project in the plan, which coincided with the economic crisis of the turn of the first five-year plans. These factors necessitated a situational prioritisation of construction projects and the concentration of resources on the most important ones to ensure the earliest possible launch. The design of the social city of the Ural Plant of Chemical Engineering is discussed in the context of the development of the master plan of Greater Sverdlovsk and the competition between the central (Leningrad branch of Standartgorproekt) and regional (Uralgiprogor Institute) design organisations. Despite the existence of preliminary designs for the social city and a general settlement scheme, the location and appearance of the residential area were determined by available financial resources and the existing transport infrastructure. Although the project was not realised, the Ural Plant of Chemical Engineering acquired a discursively real status, whose maintenance required real human, monetary, and managerial resources even when construction stopped. Noting the frequency of change of activity waves at the Ural Plant of Chemical Engineering in comparison with the unrealised infrastructure projects of the New and Modern times analysed in foreign literature, as well as public announcements of each new “revival” of construction and silence about its suspensions, the authors conclude that in the conditions of socialist industrialisation, unfinished construction had a high mobilisation value.

Published: December 2023

Aim. To evaluate the long-term results of complete bilateral internal thoracic artery (BITA) grafting and traditional coronary bypass grafting (CABG) in patients with multivessel CAD.

Material and methods. From June 2018 to December 2021, 646 CABG operations were performed in patients with multivessel CAD at the Federal Center for Cardiovascular Surgery (Krasnoyarsk). There were 178 patients receiving BITA grafting and 468 — traditional revascularization technique. After propensity score matching, 356 patients were selected, of which 99 had on-pump BITA (group 1), 178 — on-pump traditional revascularization (group 2), and 79 — off-pump BITA (group 3). There were more males (p=0,143 and p=0,547). The groups were comparable in age (p=0,343 and p=0,104), body mass index (p=0,532 and p=0,759), diabetes (p= 0,705 and p=0,667), the number of hemodynamically significant coronary stenoses (p=0,370 and p=0,595).

Results. The follow-up period lasted 32,8±8,52 months. Long-term patient survival was 83,9% in group 2,93% in group 1 (p=0,041) and 94% in group 3 (p=0,039). Freedom from cardiovascular mortality was 100% in both groups of BITA grafting and 92,5% in group 2 (p=0,001 and p=0,039), freedom from major cardiovascular events was 94,2% in group 1, 85,1% in group 2 and 98,5% in group 3 (p=0,032 and p=0,03).

Conclusion. BITA grafting is a modern effective and safe method of surgical myocardial revascularization both on- and off-pump. Up to 33 months. BITA grafting was associated with significantly better patient survival, complete freedom from cardiovascular mortality and a lower incidence of major cardiovascular events.
Sex-specific differences in hypertension
Authors: Brodovskaya T. O. , Kasyanov D. V.
Published: December 2023

The diagnosis of hypertension (HTN) has been known to doctors for many years. Current clinical guidelines represent a unified approach to the treatment and prevention of hypertension in patients of both sexes. Meanwhile, there are data that the development, course, progression and treatment of the disease may differ depending on sex.

The aim of the review was to systematize modern ideas about sex differences in hypertension, as well as to substantiate the differentiated treatment among men and women. A literature search for 2013-2023 was conducted in the PubMed, Cochrane Library, Embase, Google Scholar, eLibrary databases using the search phrase "sex differences in hypertension".

This work reflects current data regarding sex-specific differences in hypertension, including its development, blood pressure regulation, sex characteristics of risk factors, target organ damage, and features of antihypertensive treatment. Differentiated approach considering sex differences may provide novel strategies for preventing the progression of cardiovascular disease.

Aim. To evaluate the left ventricular longitudinal strain in patients with arrhythmia and undifferentiated connective tissue disease (UCTD).

Material and methods. This cross-sectional comparative study included young patients with arrhythmia and UCTD (43 men and 84 women; mean age, 30,82±8,17 years (group 1, n=127)). The control group included volunteers with single phenotypic characteristics of UCTD, comparable in age and sex (9 men and 21 women, mean age, 34,13±6,87 years (group 2, n=30)). A standard clinical examination, 72-hour electrocardiographic monitoring, and speckle-tracking echocardiography were performed.

Results. Patients of group 1 were characterized by lower global systolic longitudinal myocardial strain compared to the control group: -22,96% [-24,56%; -21,50%] in group 1 vs -24,73% [-25,25%; -23,84%] in group 2 (p=0,016). A local decrease in longitudinal myocardial strain (in two or more segments) was noted in 62,2% of patients in group 1 and 13,3% of patients in group 2 (p=0,025). In group 1, a relationship was revealed between class I premature ventricular contractions (PVCs) and a longitudinal strain decrease in the medial anterior (r1=0,253, p=0,004) and apical anterior (r1=0,253, p=0,004) segments, as well as between class V PVCs and strain decrease in the basal lower (r1=0,215, p=0,021) and middle anterior (r1=0,211, p=0,023) segments. In addition, there was a moderate correlation between mitral valve prolapse (MVP) and a decrease in longitudinal systolic strain in the basal inferolateral (r1=0,405, p=0,041) and basal anterior (r1=0,519, p=0,003) segments.

Conclusion. Local decrease in left ventricular longitudinal systolic strain in association with arrhythmia and MVP in patients with UCTD makes it possible to recommend speckle-tracking echocardiography for early non-invasive assessment of myocardial remodeling in this cohort of patients.
Modern ideas about the consequences of sympathoadrenal hyperactivation in hypertensive patients with metabolic disorders: modulation possibilities
Authors: Zhernakova Yu. V.
Published: December 2023

The prevalence of hypertension (HTN) in the Russian Federation and the world continues to grow. This is largely due to the epidemic of obesity and related conditions — metabolic syndrome and type 2 diabetes. The most common and proven hypothesis of the relationship between hypertension and obesity is the activation of the sympathetic nervous system. However, modern research shows that the consequences of sympathetic hyperactivation are not limited only to hemodynamic effects, but extend to many organs and systems. Long-term sympathetic hyperactivation can lead to insulin resistance and type 2 diabetes. Neurotransmitters affect fat cells by increasing lipolysis and leading to increased fatty acid release, the liver by increasing gluconeogenesis, and pancreatic β-cells by decreasing insulin secretion. The sympathetic nervous system plays an important role in energy management by regulating metabolic rate. Obese individuals have significantly less pronounced postprandial thermogenesis, despite a higher insulin response, while the hemodynamic response to isometric or heterometric exercise is reduced. Chronic stress serves not only as a trigger for behavioral disorders, but also directly leads to various physiological disorders, including through sympathetic activation. However, the choice of antihypertensive agents affecting the sympathetic activity in patients with obesity and metabolic disorders is very limited. According to current guidelines, β-blockers are not the drugs of choice in patients with uncomplicated HTN, since it has a weaker evidence base compared to other classes of drugs and have metabolic and other side effects. Therefore, selective I1-imidazoline receptor agonists, and in particular, moxonidine may be the drugs of choice in this category of patients. Moxonidine in combination therapy of patients with HTN and metabolic disorders, including metabolic disorders in menopause, as well as with a physiological estrogen decrease, significantly improves the effectiveness of antihypertensive therapy and increases the achievement of target blood pressure. In addition, its metabolic effects improve prognosis of such patients.
Optimal treatment strategies in comorbid patients with hypertension and dyslipidemia: the role of fixed-dose combinations
Authors: Sokolova A. A. , Napalkov D. A.
Published: December 2023

The publication reflects the modern strategy and potential of various fixed-dose combinations in comorbid patients with hypertension and lipid metabolism disorders. Based on guidelines and key randomized studies, algorithms for prescribing combination drugs are proposed depending on the clinical characteristics of patients. The priority is both to achieve target blood pressure and low-density lipoprotein levels and to maximize the impact on cardiovascular prognosis and outcomes. Of course, these algorithms are not mandatory, and in a specific clinical situation there may be any deviations even from standard treatment regimens as follows: an alternative decision of a practitioner, intolerance to therapy, special indications, and much more. However, differentiated approach to fixed-dose combinations is extremely useful in cases where it is necessary to quickly make the right decision to prescribe optimal therapy for hypertension and dyslipidemia in lack of time to comprehensively weigh all the pros and cons underlying any clinical guidelines.
HYPERGOLIC IGNITION OF A KEROSENE-BASED GEL FUEL WITH HYDROGEN PEROXIDE IN ROCKET MOTORS
Authors: Goldin Roni , Nath Syamantak , Lefkowitz Joseph K. , Natan Benveniste
Published: December 2023

This paper seeks to characterize the hypergolic ignition process of a proprietary propellant. The composition of this propellant comprises hydrogen peroxide as the oxidizer, a kerosene-based gel fuel, and sodium borohydride as an energetic additive. An experimental parametric investigation was conducted in order to correlate between different physical and chemical parameters that affect ignition delay times. The aforementioned parameters are Weber and Reynolds numbers, momentum, kinetic energy, and hydrogen peroxide concentration. The videos of the conducted drop-on-drop test were analyzed using digital image processing. The phenomenon of ignition and combustion of the gelled fuel was divided into two main events: primary ignition and fuel ignition. These delay times were calculated and plotted versus all different parameters and analyzed. An increase in momentum and kinetic energy led to a ~ 40% reduction in both primary and fuel ignition delay times. Usage of 90% hydrogen peroxide led to a decrease of > 20 ms compared to 70% hydrogen peroxide. Minimal ignition delays of 4-5 ms were observed.

Elde edilen bulgular pazarlama çevikliği ölçeğinin Türkçe ölçeğinin kabul edilebilir değerlerde güvenilir ve geçerli bir ölçme aracı olduğu sonucuna ulaşılmıştır.
Coexistence of Ammoxenus (Gnaphosidae) spider species on and between termitaria of Microhodotermes viator (Hodotermitidae) at a Karoo site
Authors: Henschel Joh , Dean W. Richard J. , Milton Suzanne J. , Dippenaar-Schoeman Ansie S.
Published: December 2023

Previous studies of some species of Ammoxenus spiders demonstrated them to be monophagous predators of certain termites. Upon observing Ammoxenus spiders preying on the hodotermitid, Microhodotermes viator, we examined the distribution of spiders on or off termitaria (termed heuweltjies) at the Tierberg-LTER study site in the Karoo using pitfall traps deployed monthly over two years. Four species of Ammoxenus were found, but only one, Ammoxenus pentheri, has been described, the other three being new to science. Their coexistence prompts questions concerning niche partitioning among several specialist predators. Our initial study revealed that Ammoxenus and other ground spiders were more abundant on heuweltjies than in the matrix between heuweltjies. The different Ammoxenus species appeared to be disparately associated or disassociated with heuweltjies and had different phenologies. This case of niche partitioning among specialist predators warrants further study.

Authors: MICOT M. , VALOIS A. , DELON F. , TEXIER G. , MORAND J.-J.
Published: December 2023

Les pathologies pilaires liées au rasage sont des motifs fréquents de consultation en médecine générale. Dans les armées, celles-ci posent la problématique de l’exemption de rasage. L’objectif de notre étude est d’évaluer les pratiques professionnelles concernant ces pathologies afin de proposer des algorithmes de prise en charge.

Une évaluation des pratiques professionnelles a été menée à partir de la diffusion d’un questionnaire à l’ensemble des médecins des forces françaises. Ce dernier comprenait une partie sociodémographique et quatre cas cliniques (irritation, folliculite, rosacée et pili incarnati).

181 médecins des forces ont répondu au questionnaire. Plus de la moitié (52,5%) a rapporté la réalisation d’au moins une exemption de rasage par mois. Le nombre d’exemptions réalisées était statistiquement associé au fait de travailler dans l’armée de terre sans que cela n’est modifié les réponses aux cas cliniques. Parmi les variables sociodémographiques, le grade était le seul facteur associé statistiquement au score global des cas cliniques et le sexe féminin avait un meilleur score concernant l’exemption de rasage.

Cette étude nous a permis d’objectiver les problématiques auxquelles sont confrontés les médecins des forces en pratique courante et d’apporter des aides et algorithmes de prise en charge à adapter selon les situations. Une prévention primaire de ces pathologies serait intéressante, notamment durant les formations militaires initiales en agissant directement chez les incorporés ou, indirectement en sensibilisant les équipes encadrantes.

Doğu Akdeniz Hidrokarbon Kaynakları, Deniz Yetki Alanları ve Sınır Anlaşmazlıkları Üzerine Jeopolitik bir Değerlendirme
Authors: DENİZLİ Cihad , AKENGİN Hamza , KARACA Ali
Published: December 2023

Doğu Akdeniz tarihi çağlardan beri birçok uygarlık ve devletin hâkim olmak için güç mücadelesinde bulunduğu ve ele geçiren devletlerin ise o dönemin en güçlü devlet veya imparatorluğu haline geldiği stratejik bir iç deniz olmasının yanında doğu ve batı arasındaki ticaretin omurgasını oluşturan jeopolitik açıdan dünyanın merkezi diyebileceğimiz bir konumdadır. 21. yy. başlarında bölgede keşfi yapılan hidrokarbon (petrol-doğalgaz bileşimleri) kaynakları bölgenin jeopolitik niteliklerine yeni ve çok önemli bir faktör eklemiştir. Doğu Akdeniz havzasında menfaati olan devletler bir taraftan bu bölgedeki kaynaklara sahiplenmek için kendi aralarında güç mücadelesine girerken, bir taraftan da küresel boyutta faaliyet gösteren enerji şirketlerini bu kaynakları araştırmak ve çıkartmak için davet etmişlerdir. Bölgede yer alan devletler deniz yetki alanlarını belirlemek için MEB (Münhasır Ekonomik Bölge) sınırlarını 2’li 3’lü anlaşmalarla garanti altına almaya çalışmıştır. Bunun için her devlet kendi yetki sınırını belirlerken farklı özelliklerini ön plana çıkarmak istemiş bu da Doğu Akdeniz’de deniz yetki sınırları anlaşmazlıklarını ortaya çıkarmıştır. Bölgede bulunan devletlerden Türkiye, Libya ve KKTC farklı bir blok, Yunanistan, Mısır, İsrail ve GKRY ise farklı bir blokta yer almıştır. Bu ikili yapının birbirleriyle yaptıkları MEB sınır anlaşmaları yine birbirlerinin deniz yetki alanlarının çakışmasına neden olmuştur. Bu anlaşmalar sırasında belirlenen ortay hatlar ve diyagonal hatlar esası bu sorunların büyümesine ve anlaşmazlıklar çıkmasına yol açmıştır. Bu çalışmanın amacı Doğu Akdeniz havzasında imzalanan MEB sınırlarını ve uyumsuzluklarını elde ettiğimiz ulusal ve uluslararası verilerden yola çıkarak Arc Map 10.4 sistemiyle haritalayıp coğrafi bir perspektifte çözüm önerileri sunmaktır.

6 Şubat Kahramanmaraş depremleri sonrası ortaya çıkan enkazın kaldırılması ve depolanacak sahalara taşınması problemi ortaya çıkmıştır. Bu kapsamda çalışmanın amacı, hızlı enkaz kaldırma sürecinde molozların depolanacağı en uygun alanları tespit etmek ve mevcut alanların uygunluğunu tartışmaktır. Hatay’daki orman, mera, zeytinlik, tarım alanları, sulak alanlar, yerleşim alanları, özel koruma alanları ve yerüstü sularını göz önünde bulundurarak atık depolamasına ilişkin kanun ve yönetmeliklere göre uygunluk analizleri yapılmıştır. Çalışmada molozlar için uygun alanların tespiti için kriterler belirlenerek Analitik Hiyerarşi Süreci (AHS) ve Fuzzy AHS yöntemleri karşılaştırmalı olarak kullanılmıştır. 9-11 Mart 2023 tarihlerinde Hatay’daki saha çalışmalarında mevcut moloz depolama alanlarında yerinde gözlem tekniği uygulanmıştır. Analiz sonuçlarından elde edilen ve moloz dökümüne uygun olduğu tespit edilen alanlar ile mevcut döküm sahalarının konumları karşılaştırıldığında uyumsuzluklar tespit edilmiştir. Araştırmanın bulgularına göre Hatay’da belirlenen moloz depolama alanlarının konumları incelendiğinde uzun vadede bölge için önemli çevresel, toplumsal, ekonomik, ve kültürel problemlere yol açacağı öngörülmektedir. Dolayısıyla bu çalışmaya göre, kriz anında hızlı karar verme zorunluluğu nedeniyle seçilen moloz depolama sahalarının uzun vadeli problemlere yol açacağı; bu bağlamda karar verme sürecinde bilimsel kriterlere dayanan Coğrafi Bilgi Sistemleri (CBS) teknolojilerinin kullanılmasının gerekliliği ortaya çıkmıştır.
Com es poden museïtzar els patrimonis incòmodes? El paper de les biografies personals en els espais i museus de memòria traumàtica
Authors: Roigé Xavier
Published: December 2023

Molts museus de memòria integren en les seves exposicions biografies personals per reforçar les seves explicacions i continguts. L’article reflexiona sobre les tècniques i estratègies utilitzades per recollir i mostrar aquests relats, tot assenyalant-ne les possibilitats però també els límits. S’analitzen diversos exemples de museus d’arreu del món per veure com es presenten i utilitzen els testimonis biogràfics i la seva interrelació amb els objectes exposats, i s’indiquen també els debats sobre els problemes ètics d’aquestes presentacions, en especial els dubtes sobre el grau de literalitat de les narracions que han de fer-se sobre el sofriment de les víctimes. La utilitat social i expogràfica dels relats personals en aquest tipus de museu és molt important, ja que permeten una aproximació més pròxima i vivencial dels fets viscuts. S’assenyala que, malgrat el paper central de les entrevistes i els relats en l’antropologia, la nostra disciplina ha contribuït poc a la configuració d’aquests museus, tot i que un major enfocament antropològic podria contribuir a remarcar el paper dels relats biogràfics en les exposicions i permetria superar alguns dels problemes conceptuals i expogràfics que es plantegen.

DNA Barcoding Standard Operating Protocol, Plants and Lichens at RBGE, Lab methods: DNA extraction v1
Authors: L Forrest Laura , Yahr Rebecca , Hart Michelle
Published: December 2023

This is part of the collection DToL Taxon-specific Standard Operating Procedures for the Plant Working Group (protocols.io). The SOP collection contains guidance on how to process the various land plant taxa within the scope of the Darwin Tree of Life project. The guidance specifically refers to the tissue samples needed for DNA barcoding (which takes place at the Royal Botanic Garden (RBGE)) . Every specimen is submitted for DNA barcoding first before potentially being sent to the Wellcome Sanger institute.

Advanced Blast Simulator (ABS) blast model in rat - VandeVord Lab v1
Authors: not provided pvord
Published: December 2023

This is a protocol to describe the materials and methods utilized to perform preclinical traumatic brain injury (TBI) using a blast model for rodents. Blast waves are generated using a custom Advanced Blast Simulator (ABS). The ABS consists of three distinct sections to create, develop, and dissipate the blast wave. A blast wave develops following a helium-driven rupture of calibrated acetate membranes. The passive end-wave eliminator was located downstream of the test location to facilitate the dissipation of the blast wave through a series of baffles. As a result, specimen at the test location within the ABS are exposed to a single peak overpressure representing a free-field blast exposure. The posting of this protocol is part of the mission of the PREClinical Interagency reSearch resourcE-TBI (PRECISE-TBI, precise-tbi.org) to improve clinical translation of therapeutics by providing an online catalog and standardized protocols to reduce the variability of model usage between laboratories.
Water absorption of food wheat flour – comparison of direct and indirect methods
Authors: Sedláček Tibor , Švec Ivan
Published: December 2023

The study aims to compare three methods used for the evaluation of water absorption of wheat flour: a) a direct method consisting of a standard procedure on a Farinograph-E device and b) two indirect methods, namely NIR spectroscopy and centrifugation. Forty-four samples of Czech food wheat were collected from the harvest year 2021. Namely, 23 samples of food wheat from the standard maturity collection ‘SM2’ and 21 samples from the early maturity collection ‘EM2’. All wheat samples were ground to obtain wheat flour of fine granulation. The flour samples were characterised by protein and ash content of 10.55-14.75% and of 0,59-0.63%, respectively. The water absorption ranged from 55.7% to 63.2% flour weight (Farinograph standard procedure), 60.1-67.1% flour weight (NIR spectroscopy), and 67.6-77.2% flour weight (centrifugation). Based on the results obtained by ANOVA statistical analysis, no significant difference was found for all qualitative parameters of SM2 and EM2 (p = 95%). According to the mentioned methods for both indirect determinations of water absorption in the sets SM2 and EM2, the prediction of the standard farinograph water absorption was more accurate using the NIR technique (minimal and maximal pair differences of 1.01 and 6.86 percentage points, in contrast to 1.78 and 14.87 percentage points for the centrifugation method). Linear regression confirmed the primary importance of protein content for the water absorption values. Also, the ash content should be considered because it reflects the dietary fibre level, and the fibre influences the water absorption values as well.

In the Zagreb city area extensive monitoring of water for human consumption has been carried out for years, which includes several dozen different chemical, biological and physical parameters. Given the daily water intake in our bodies, the possibility of ingesting certain contaminants via water has a significant role. This especially applies to nitrates, which are in the second place of importance, since it has been found that the water is their source. In this paper, we present results of the presence for the following contaminants: aluminum, cadmium, chlorate and chlorite, nitrate and mercury in water that can be consumed via water in the city of Zagreb for the period 2016-2020. The results indicate stable average annual values of monitored contaminants, except for aluminum and chlorates, for which it was found that the values of annual averages differ several times. However, even in cases of higher values, their contribution to water intake does not pose a risk to the health of consumers, nor it significantly contribute to their overall intake. Still, given the assumption that this is a specific exposure, to which the consumer is tied to the place of residence, it is important to constantly monitor trends, so that each exposure is kept to a minimum.

Published: December 2023

During the summer months from 2014 to 2016, water was sampled at two lakes in Zagreb, Jarun and Bundek, with the aim of determining the number of colonies of microbiological indicators of Escherichiae coli and intestinal enterococci. We have investigated the dependence of microbiological water quality indicators on sampling points. Also, we were interested in determining the influence of the season of the year. This research identified that regular monitoring of microbiological indicators is necessary, especially at locations used by people for recreation or other purposes, in order to prevent possible infections.

Published: December 2023

The offered social-scientific analysis is based on a critical discussion of key problems present in the Slovak media environment, such as the ethical self-regulation of the media, freedom of expression, the right to obtain information, or the legal protection of the sources of information. The study also refers to available scholarly sources and the previously published body of knowledge to assess the development of the media system in Slovakia over the past 30 years, outlining the country’s (in)ability to foster deliberative communication and democracy. The results suggest that the legal and ethical aspects of the Slovak media system do support some of the principles of deliberative communication, specifically freedom of expression and free access to information; however, free speech is not sufficiently confronted with the boundaries of protecting privacy and human dignity to prevent defamation and hate speech. Media autonomy based on the possibility of self-regulation is not sufficiently developed either. A serious problem is the lack of transparency in the media.

Authors: Faizulina R. R. , Borodkin I. N. , Taranets K. O.
Published: December 2023

Introduction. Colorectal cancer (CRC) is one of those cancer types which have many worldwide organized screening programs. Those screening programs help to reduce colorectal cancer morbidity and mortality. Aim. To evaluate the results of screening colonoscopy with simultaneous removal of benign epithelial formations on an outpatient basis using “cold” methods, as well as its effectiveness in the prevention of CRC. Materials and methods. A retrospective analysis of the results of colonoscopy in outpatient conditions performed at the N. I. Pirogov Government City Clinic (Orenburg) for the period 2018–2021 was performed. The study included indicators of screening colonoscopy performed in asymptomatic patients. The main evaluated parameters are: the type of polyp according to the Paris classification, the results of histological examination, the frequency of complications, as well as the quality indicators of colonoscopy (preparation according to the Boston scale, the time of removal of the device, adenoma detection rate (ADR), polyp detection rate (PDR)). Results. A total of 4,588 screening colonoscopies were performed, frequency of adenomas detection – 35,3 %, 1,041 neoplasms were removed (of which 456 (44 %) neoplasms were removed with biopsy forceps, 585 (56 %) neoplasms were removed with a cold loop as a single block). In 622 (59,7 %) cases, the macroscopic form of neoplasms is type 0–IIa, in 326 (31.3 %) – type 0–Is, in 93 (9 %) – type IIa + IIc. According to the results of histological examination, the sessile type of structure was diagnosed in 158 (15.2 %) cases, non – sessile – in 883 (84.8 %). In 276 (26.5 %) cases, were detected adenomas with micro-foci of adenocarcinoma (tumor in situ). During the study period (2018–2021), one complication (0.09 %) of outpatient polypectomy by the “cold” method was observed. This complication was manifested by automatically stopped bleeding. Conclusion. Screening colonoscopy is one of the most effective diagnostic methods to detect CRC in asymptomatic patients. The “cold” polypectomy method has an important role in the prevention of CRC, as it is a safe procedure which can be performed on an outpatient basis.
Data Friction and Precarious Knowledge: IEA and the Movement of Data in the 1960s and 1970s
Authors: Landahl Joakim
Published: December 2023

The creation of international large-scale assessments in the 1960s and 1970s was inevitably a product of the movement of data. Large amounts of information about school performance circled the globe: first collected in individual schools, then aggregated at the national level, then sent to an international centre, and finally returned for further national analysis and dissemination. While the movement of data was a prerequisite for international testing, there was an inherent risk in how the work was organised. The concepts of data friction and precarious knowledge are used to describe how the pace of information transfer was slowed or how information was in danger of being lost as it circled the globe. The movement of data brought with it the double possibility of creating and destroying knowledge.

Authors: Zakharova Irina , Bock Annekatrin
Published: December 2023

What is made in/visible in datafied educational settings? How are in/visibilities entangled with data practices in schooling? In this contribution, we provide an overview of recent literature on digital technologies and datafication of education and consider four kinds of interrelations between in/visibilities and data practices: decontextualisation, in/visibilising of data work, black-boxing, and fore- or backgrounding. Scoping some examples of research that capture aspects of invisibility and visibility, we reflect on conceptual and methodological underpinnings of how to study in/visibilities and data practices in education.

Published: December 2023

A partir de 2.188 registros de corderos de raza Churra se ha estimado la heredabilidad y los parámetros ambientales del peso al nacimiento, peso al destete y ritmo de crecimiento en la fase predestete. La heredabilidad ha sido estimada a partir de un diseño de medios hermanos. Para los análisis estadísticos se ha seguido el método de mínimos cuadrados (LS) y el de máxima verosimilitud (ML). Las estimaciones que se han obtenido para las variables indicadas, peso al nacimiento, peso al destete y ritmo de crecimiento en la fase predestete, han sido, respectivamente: 0,29 + 0,07, 0,17 + 0,05 y 0,16 + 0,05. Para el peso al nacimiento, peso al destete y ritmo de crecimiento predestete, los factores de variación ambiental rebaño, año de parto y sexo mostraron una influencia estadísticamente altamente significativa. Para el peso al destete, la edad del cordero fue en nuestro estudio el factor de variación más importante, explicando el 13,7% de la varianza total. Para el peso al destete y el ritmo de crecimiento predestete, la estación de parto fue un factor estadísticamente altamente significativo mientras el número de lactación de la madre lo fue sobre el peso al nacimiento y al destete.
