New nematode species and genera (Nematoda: Chromadorea) from cold seeps on Hikurangi Margin, New Zealand
Authors: Leduc Daniel
Published: January 2023

Relatively little is known about the taxonomy and ecology of deep-sea nematode species inhabiting cold seep habitats. The available data show that cold seep nematode communities are typically characterized by low diversity and are often dominated by a single species, although no nematode taxon appears to have a strong association with methane seepage. In July 2019, a research voyage to New Zealand’s Hikurangi Margin provided an opportunity to characterize the nematode species communities of New Zealand cold seeps, which had not been investigated until now. Here, six new species and two new nematode genera of the class Chromadorea are described from macrofauna cores obtained at three seep sites (Mungaroa, Glendhu, and Uruti South) on Hikurangi Margin from 1227 to 2077 m depth. The species described here represent a wide range of feeding groups, ranging from deposit feeders (Linhomoeus pycnocricus sp. nov., Deraionema barbatum gen. et sp. nov.) to microvores (Aulostomonema abyssum gen. et sp. nov., Aegialoalaimus magnus sp. nov.) and epigrowth feeders (Desmodora parapilosa sp. nov.). The diet of Siphonolaimus curtisensillus sp. nov., which is characterized by an unusual stylet-like feeding apparatus, remains to be determined, however the presence of several different feeding modes in the species described here indicates that a range of food sources are exploited by macrofaunal nematodes at the study sites. Desmodora, Linhomoeus, and Aegialoalaimus have been reported from cold seep habitats previously, however no records of Siphonolaimus from cold seeps could be found in the literature. Aulostomonema gen. nov. does not appear to have a close association with seeps, whilst Deraionema gen. nov. appears to be restricted to the centre of the seep sites where methane seepage is likely strongest. Ongoing work on the ecology and distribution of nematode communities at the Hikurangi Margin seep sites will help determine spatial patterns in abundance and species distributions in more detail, including the identification of any species/taxa with affinities with methane seepage.
On the Issue of Land Ownership in the Smolensk Land and the Mstislav Principality of the 15th Century
Authors:   independent researcher, Shekov Alexander V.
Published: January 2023

The article deals with some issues of feudal land tenure in the Smolensk region and in the Mstislav principality of the 15th century, which are insufficiently covered in historiography. It is clarified that the lands in the Molokhva volost, transferred by the Lithuanian Grand Duke Vitovt to the Mstislav principality, were returned to Smolensk land no later than 1448, most likely around 1442. The following objects are located — Rzhavesk settlement near Molokhva, the Nagat volost on the left bank of the Dnieper river, the village of Moshenskoye in Upper Posozhye; they were granted by the Lithuanian rulers to the princes Muncha Selemenevich, Kroshinsky and S. I. Glinsky in the Smolensk land. Obviously even while under Vitovt, the princes Kroshinsky received possession not only of the northeastern Vyazma volosts, but also of the land near Smolensk. Most likely, Prince S. I. Glinsky received possession of the southeastern Vyazma volosts from Vitovt. By 1440, this prince owned the parish of Nagat, which was returned no later than 1447/48 г. to Prince F. Kroshinsky as his fatherland. The brother of Prince S. I. Glinsky, Boris Ivanovich, received the village of Khodosovo near Mstislavl, presumably from the Lithuanian Grand Duke Sigismund Keistutovich, in 1438 — early 1440. Near Nagati in Upper Posozhye, King Casimir IV granted in 1448 to Prince F. L. Vorotynsky yard Nemchinovskoe. Somewhat to the south, in 1481, this king transferred his court Bolvanichi on the left bank of the Sozh river with dependent lands to the authority of princes M. I. and F. I. Odoevsky. Lithuanian rulers of the 15th century granted land in the Smolensk region not only to local boyars, but also to members of various princely families. At the end of this century, individual Smolensk landowners, who held high administrative positions, created their own seigneuries in this region. First of all, these are the Smolensk treasurer Prince K. F. Kroshinsky and the famous dignitary I. S. Sopega.
Key Objects of the Nuclear Legacy of the Soviet Nuclear Project: Lake Karachay
Authors:   South Ural Technological University, Bochkareva Irina A.
Published: January 2023

The article considers the formation of Russis’s nuclear-industrial complex in the light of radioecological consequences. The USSR atomic project is known to have played a major role in the history of our country in the second half of the 20th century, largely determining its political and socio-economic development. The main result of its implementation was the creation of the country’s nuclear shield, which made it possible to ensure the defense capability and national security of our state, which has not lost its relevance today. Along with this, the Soviet nuclear program gave rise to a whole range of problems, including those in the field of ecology and environmental protection, and led to many unforeseen long-term consequences. On the example of the enterprises of the nuclear complex of the Urals, and, first of all, the chemical plant «Mayak» (now the production association «Mayak»), which played a key role in the creation of atomic weapons, the reasons for the emergence of nuclear and radiation legacy are identified, the environmental consequences and risks associated with it are assessed, and the content of measures to eliminate them is analyzed. Given that the radioecological problems of the development of the nuclear industry are still acute, the experience of the past is especially in demand. Further study of the complex of issues related to the nuclear legacy and the ongoing efforts to resolve them will make it possible to supplement the existing understanding of the content and consequences of the implementation of the domestic uranium project, the history of Russia and its regions affected by the activities of nuclear enterprises, as well as take a fresh look at the possibilities and risks of development of the nuclear industry.
The Network of Rural Settlements of the Tomsk District in the 1920s: Quantitative and Qualitative Characteristics
Authors:   Tobolsk Complex Scientific Station, Ural Branch of the RAS, Tatarnikova Anna I.
Published: January 2023

The paper presents the characteristics of the rural settlement network of the Tomsk District of the Siberian Territory, which existed in 1925–1930 as an independent administrative-territorial unit formed from the territories of the former Tomsk and part of the Mariinsky uezds, as well as five districts of the Narym Region of the Tomsk province. For the first time, data on the number, typology, and size of rural settlements of the district by the number of yards and the number of inhabitants in the 1920s are presented. The dvornost’ and population size of settlements of different statuses are analyzed, the average size of a peasant yard is determined depending on the type of settlement by the number of persons living in it. The obtained statistical data on the state of the network of rural settlements of the Tomsk district are compared with similar indicators of the pre-revolutionary period. The conclusion is made about quantitative and qualitative changes in the development of the rural settlements network of the district in the first years of Soviet power, expressed in the appearance in the typical structure of settlements with a new status — communes, state farms, agricultural artels, experimental fields, as well as in an increase in the share of hutor, vyselki, zaimka in the total number of rural settlements. The influence of socio-economic modernization on the network of settlements, an increase in the number of new types of settlements along the Trans-Siberian railway (stations, booths, barracks, sidings) is traced. There was a reduction in the size of farmsteads in rural areas, an increase in the density of the settlement network due to the spread of individual land management in the form of farms.
Reference Maps on Building Materials for the Western Front of the Russian Army (1915–1918)
Authors:   Great Russian Encyclopedia, Grishin Evgeniy S.
Published: January 2023

The article gives a description of a special group of the cartographic sources of the First World War period — building materials maps. The methods for compiling maps and the source materials for them are revealed. The maps were elaborated by the “Commission on Raw and Chemical Materials” having been a part of the “Military Technical Assistance Committee”, in order to facilitate the material support of Russian troops on the Western Front with various natural materials that could be used for the fortification and construction works, as well as for laying the communication lines. In total, at least 11 sheets of maps of similar content are known to have been compiled. Using the sheet № 14 for the Vilna area as an example, the main features of the considered group of sources are revealed: structure, graphic design, main sections of the explanatory note, content and legend of the map itself. Various aspects of the significance of the source are indicated: it is not only a carrier of information about the natural resources of individual regions of the Russian Empire, but also a remarkable example of the preparation of operational cartographic information through the use and adaptation of the maps by I. A. Strel’bitsky. The maps reflect not only the extent of prospecting for the regions’ natural resources and their geological knowledge, but also contain valuable information on their exploitation; the same can be put down to the explanatory note, which, in addition to the specified information, contains data on water resources and their use. It should be noted that the maps on building materials practically have not been cited either in special studies on the history of the First World War, or in works devoted to the history of cartography.
Two Sieges of the Cossack Village of Sarkand in August 1918 on the Pages and Maps of the Diary of N. D. Koltz
Authors:   Institute of History and Archaeology, Ural Branch of the RAS, Weber Mikhail I.
Published: January 2023

The paper presents the so-called diary of a White officer — lieutenant colonel of the Siberian Cossack Nikolai Dionisievich Koltz. As our research has shown, it is more correct to call it the journal of military operations of the White partisan Cossack detachment. This historical source makes it possible to reconstruct a little-known episode of Russian Civil War in the region of Semirechye in Central Asia — two sieges of the Cossack village of Sarkand by the Reds in August 1918. During these sieges, the Cossacks of the Lepsinsky and Kopalsky counties of the Semirechensk region, who rebelled against the Soviet government, successfully repulsed several assaults of the village by the Red Guard detachments sent to pacify the uprising from the city of Verny (now Alma-Ata). A distinctive feature of this document is the accompaniment of the text by three croquis showing the course of military action during both sieges of the village.
Origen y uso en español de la acepción cristiana de at(h)leta. Un recorrido por los tratados y escritos religiosos de la 2ª mitad del siglo XVI y 1ª del XVII
Authors: Carmona Centeno David
Published: January 2023

A partir de la interpretación de un conocido pasaje de Pablo de Tarso (I Cor. 9, 24-27), los Padres de la Iglesia se sirvieron de los términos ἀθλητής / athleta para denominar al defensor de la fe cristiana y, como consecuencia, al creyente que era asesinado y alcanzaba el martirio. Mientras que en italiano se origina y consolida el grecismo con esta acepción desde época muy temprana (aparece por primera vez en la Divina Comedia, de Dante), no se halla en español hasta 1601. En este trabajo, se realiza un recorrido por los tratados y escritos de carácter religioso del período comprendido entre la segunda mitad del siglo XVI y la primera del XVII, gracias al cual se podrá determinar el origen y el asentamiento de la acepción cristiana de atleta en español, donde Lope de Vega juega un papel de vital importancia con la incorporación sistemática del vocablo a diferentes obras de poesía, teatro y prosa de temática religiosa.

Introduction Maternal sensitivity and mentalization are fundamental for children’s mental health development. These skills have been negatively associated with maternal postpartum depressive symptomatology. Moreover, its prevalence increases in low socioeconomic and psychosocial risk contexts, where the access to treatment is scarce. Even though Attachment Based Interventios, such as Video-Feedback has been internationally recognized as an effective intervention. Its cost, as well as the need for language translation and cultural adaptation makes it difficult to implement in Latinamerican countries. Aim The present study aims to assess the feasibility and acceptability of an online Video-Feedback intervention informed n mentalization aimed at mother-infant dyads with depressive symptomatology who attend Chilean public health centers. Method This is a pilot randomized clinical trial with two groups of 60 mother-infant dyads between 4 and 12 months of age. Participants will be randomly assigned to control and experimental groups in a 1:1 ratio. Even though both groups will receive usual treatment, the experimental group will also receive the present video-intervention. At the end of the study, feasibility will be assessed based on focus groups aimed at interveners and quantitative outcomes such as recruitment rate, questionnaire completion rate and intervention completeness. Acceptability will be assessed from in-depth interviews with participants. In addition, effect sizes of primary and secondary outcomes will be calculated. Expected results Results are expected to generate parameters to design a larger-scale clinical trial and to preliminary assess the effect of the reported mentalization-informed intervention on maternal sensitivity. Additionally, it seeks to contribute with a mental health intervention for low-income mother-infant dyads, which can be implemented remotely, at a low cost, and that would be suitable for implementation at a mental health care system policy. The protocol of this trial’s design was registered at Clinical Trials (NCT04748731).
Identifying the impact of methanol-diesel fuel on the environment using a four-stroke CI engine

Published: January 2023

This work aims to investigate the influence of blending diesel fuel with different percentages of methyl alcohol on reducing the emission of exhaust gases. The study was performed using a laboratory diesel engine, which is an internal combustion, single-cylinder, and four-strokes engine. The study involved investigating three volume percentages of methyl alcohol (methanol), which are 7, 14, and 21. The emission results of the blending fuels were compared with that of non-blending fuel. The analysis of the exhaust gases was done under three engine loads, which are two, four, and six N.m, with a constant speed of 2000 rpm. The analysis involves measuring carbon oxides (CO and CO2), unburned hydrocarbons (HC), nitrogen oxides (NOx), and particulate matter (PM). The results showed a positive impact of methanol on reducing the emission of all gases except NOx. Increasing the methanol ratio increases the reduction of the emissions of CO, CO2, PM, and HC, where the highest reductions of the gaseous emissions were observed with the percentage of 21% of methanol under all engine loads. Specifically, the drop recorded by using 21% of methanol was 69-83% for CO, 60-69% for CO2, 80-83% for HC, and 25-30% for PM. These reductions in emissions are assigned to the high oxygen content of methyl alcohol that influences the complete combustion of diesel. On the other hand, the NOx emission increased by 135-346%, but a possible reduction in these emissions can be achieved through a proper engine modification. The results of this investigation provide essential insights that would inspire using methanol as a fuel additive with modifying the diesel engines to be compatible with blending fuel.
Tres sellos para un infante: documentos de Don Felipe, abad de Valladolid y arzobispo electo de Sevilla (1229/31-1278)
Authors: BELMONTE FERNÁNDEZ Diego
Published: January 2023

This work aims to study and value the few original documents, and the seals that they carry and that have come down to us, issued by a character who has gone through something unnoticed in the history of the Church of Seville, the infante Don Felipe, son of Fernando III and brother of Alfonso X, the Wise. Despite such notable kingship, the figure of the person who was appointed to occupy the Seville archiepiscopal seat in the first place after the conquest of the city by Christian power, has always been overshadowed for various reasons. However, the few documents located present an interesting triple representation of the infant according to the different moments of his life curriculum. Although these pieces have been used as historical sources, they have never been studied by themselves.

El objetivo del presente trabajo es estudiar y poner en valor los escasos documentos originales, y los sellos que portan y que han llegado hasta nosotros, emitidos por un personaje que ha pasado algo desapercibido en la historia de la Iglesia de Sevilla, el infante don Felipe, hijo de Fernando III y hermano de Alfonso X, el Sabio. A pesar de tan notable parentela, la figura del que fuera designado para ocupar la sede arzobispal hispalense en primer lugar tras la conquista de la ciudad por el poder cristiano ha estado siempre ensombrecida por varias razones. Sin embargo, los pocos documentos localizados presentan una interesantísima triple representación del infante acorde con los distintos momentos de su currículo vital. Estas piezas, si bien han sido utilizadas como fuentes históricas, no han sido nunca estudiadas por sí mismas.

Published: January 2023

Artificial Intelligence (AI) is expanding with colossal applications in various sectors. In the healthcare sector, it is booming to make life simpler with utmost accuracy by predicting, diagnosing and up to care with the help of Machine Learning (ML) and Deep Learning (DL) applications. Modern computer algorithms have attained accuracy levels comparable to those of human specialists in medical sciences, although computers often do jobs more quickly than people do. It is also expected that there will not be a mandate for humans to be present for the jobs that machines can do, and it is gaining the highest peak because of good trained artificial models in the medical field. ML enhances the therapeutic process and improves health by encouraging more patient participation. ML may get more accurate patient data when used with the Internet of Medical Things (IoMT) and automate message notifications that prompt patients to respond at certain times. The motivation behind this article is to make a comprehensive review of the on-going implementation of ML in medical science, what challenges it is facing now, and how it can be simplified for future researchers to contribute better to medical sciences while applying it to the practitioners' jobs easier. In this review, we have extensively mined the data and brought up systematised applications of AI in healthcare, what challenges have been faced by the experts, and what ethical responsibilities are liable to them while taking the data. We also tabulated which algorithms will be helpful for what kind of data and disease conditions will be useful for future researchers and developers. This article will provide a better insight into AI and ML for the beginner to the advanced developer and researcher to understand the concepts from the basics.

It is of interest to investigate the effectiveness of a mindfulness-based stress reduction program on stress and salivary cortisol among substance abuse patients. There were 60 drug addicts who were receiving treatment at the addiction centre. Samples are divided into 30 drug abuse patient experimental and 30 substance abuse patient control groups using the simple random sampling approach. Salivary cortisol, a pre-test stress biomarker, was measured and used to analyse the results. The MBSR programme was administered over the course of eight weeks, with two 1-hour sessions held each day, with a cap of 15 participants. The biomarker for stress (salivary cortisol) will be obtained once again at the end of the program to assess the post-test level of perceived stress and compare it to the results. Patients showed improvements in stress level (p < 0.05) following the 8-week MBSR program. The mean level of blood cortisol in the experimental group was 18.08 (3.62), which was dropped to 7.54 (1.29) before the intervention. The mean cortisol level in the experimental group differs by 10.54 (3.45) between pre and post intervention following the intervention (p value is < 0.005). Thus, there is a difference between the experimental conditions before and after the intervention. The mean serum cortisol level in the pre-test is 17.30 (2.34) and the mean serum cortisol level in the post test is 17.15 (2.31) in the control group (p value is > 0.005). Data shows that there is a significant difference between the groups. MBSR may be a beneficial intervention for reducing stress, in Patients taking treatment in de addiction centre.

Kant y la melancolía: topografía de un fenómeno liminal
Authors: Morán Roa Alberto
Published: January 2023

En este artículo elaboraremos una definición kantiana de melancolía a partir de las descripciones planteadas a ambos lados del giro crítico. Este análisis nos permite asimismo reparar en aspectos importantes del pensamiento kantiano, tales como la relación entre la razón y las afecciones o el modo en que se constituye la experiencia del mundo. Subrayamos el carácter liminal de la melancolía, que Kant presenta como una afección del alma pero también como un temperamento próximo a la experiencia de lo sublime y a la moral. Estos vínculos, particularmente con lo sublime, aportan interesantes claves acerca de la relación propuesta por Kant entre la subjetividad y el límite.
Reconsiderando el “consecuencialismo kantiano”
Authors: Oliveira Martin
Published: January 2023

En este trabajo hemos tratado de evaluar el consecuencialismo kantiano que defiende David Cummiskey. La inspiración kantiana de esta particular lectura es innegable. Parte de una teoría del valor moral muy semejante a la del filósofo de Könisberg, trata muchas de las cuestiones textuales de las principales obras kantianas pero llega a conclusiones radicalmente distintas. En esto último radica el principal atractivo de una interpretación consecuencialista de Kant.  Mientras que uno podría sugerir que la tradición leyó incorrectamente a Kant y que la perspectiva de Cummiskey es la mejor reconstrucción del pensamiento de este filósofo, hay elementos para poner esto en duda.

Si no fuera por el libro sobre Kant que Roberto Torretti publicó hace 55 años, la filosofíaen Hispanoamérica tendría un rostro distinto: uno menos vital y menos relevante. Manuel Kant:estudio sobre los fundamentos de la filosofía crítica 1 es una obra única. Proporciona el accesoprincipal y sin duda privilegiado a la filosofía kantiana para muchas generaciones deinvestigadores especialistas y no especialistas que leen español. Torretti es también autor devarios ensayos clásicos sobre la filosofía de Kant, la mayoría de los cuales quedaron recogidosen el libro Variedad en la razón: ensayos sobre Kant 2 y en cinco volúmenes de estudiosfilosóficos (1957-2014) 3 . Dos de las principales pasiones de Torretti, cuyo desarrollo profesionaly académico le valdrían una gran notoriedad internacional, emergen con nitidez en el primerlibro kantiano: la historia y filosofía de la física y de la geometría del siglo XIX y parte del sigloXX. Torretti es autor de obras fundamentales en esos campos.

Epidermodysplasia verruciformis is an autosomal recessive skin disease usually presenting as multiple flat warts and pityriasis versicolor-like macules in early youth, possessing a great risk of developing skin cancer due to a lack of defense against beta HPV. Herein, we report the case of a 29-year-old female, a known case of EV, who presented with a verrucous growth on the forehead persistent for the previous one year. While clinical and dermoscopic examinations led to the suspicion of squamous cell carcinoma, it was confirmed by histopathological examination following a skin biopsy.

Morphea is a sclerotic condition limited to the skin corresponding to various clinical entities depending on the extension of the lesions, their linear nature, and their depth [1]. It is a relatively rare condition in children. Although almost never life-threatening, it may in some cases be responsible for functional and/or esthetic disability [2] with a major impact on quality of life, hence the importance of its early diagnosis and treatment. Herein, we report the case of juvenile morphea in plaques. A ten-year-old child with a history of the first-degree consanguinity of the parents and a family atopic condition presented with four oval, hyperpigmented plaques on the thorax with a pearly-white center (Fig. 1), which were sclerotic on palpation. Dermoscopy revealed an appearance resembling a white cloud (Fig. 2). The rest of the clinical examination was unremarkable. Raynaud’s phenomenon was absent, the genital tract was intact, and no visceral involvement was noted. A skin biopsy was performed confirming the diagnosis of morphea. The child was treated with dermocorticoids with good evolution.

Published: January 2023

Ear piercing is highly popular globally. The traditional methods of ear piercing include passing a wire, followed by jewelry, piercing guns, intravenous cannula (18G) employed to pierce the ear lobule [1]. Other methods include the eyelet-type Teflon tube, angiocatheter, magnetic earrings, and a 14- or 16-gauge trocar needle antrum [2]. Other safe options for body piercing include solid gold of 14 or 18 karats, niobium, titanium, and platinum [3]. We feel that the cannula method is effective, as piercing is globally popular and the technique is easy and single staged. We made little modification to the technique, which is convenient and friendly to the patient.

Sir, Psoriasis is a chronic inflammatory skin condition affecting roughly 2% of the population. Erythrodermic psoriasis (EP) is its rare and severe variant [1]. It is characterized by acute flare-ups induced by various factors, yet some reports have described the onset or flare-up of EP induced by vaccination. To our knowledge, only two such cases following COVID-19 vaccination have been reported. Herein, we report a case of an EP flare-up after COVID-19 vaccination. A 47-year-old male was referred by our emergency department with diffuse erythema, desquamation, fever, and a poor general condition, arising ten days after the reception of the first dose of the Sinopharm vaccine. He had a history of plaque psoriasis, yet used only topical treatments. He denied any past vaccination-related reaction, recent medication changes, or recent infection. A physical examination revealed diffuse erythema and desquamation on the entire body (Fig. 1a). Initial laboratory investigation revealed hyperglycemia and incidentally discovered diabetes. A COVID-19 PCR test was negative and the peripheral blood smear was normal. He had no history of malignancy and the tumor marker tests were negative. Histopathology was also compatible with erythrodermic psoriasis. He was, thus, diagnosed with the exacerbation of erythrodermic psoriasis associated with the administration of CoronaVac. We commended methotrexate and local treatment with very good improvement.

Background: Voluntary depigmentation (VD) is a cosmetic practice with potentially local and systemic complications such as hyperglycemia. The aim of this study was to find determinants of hyperglycemia in women who practices VD. Methodology: we carried out a retrospective cohort study with from February to August 2020 in four hospitals in Yaoundé, Cameroon. This study included two groups of women: one made up of women who practices VD (exposed group) and the other of women who does not practices VD (group of “unexposed”). Data were collected on CSPro 7.4 software and analyzed on SPSS 25 software. The association between hyperglycemia and VD was measured using Chi-square test. Results: We recruited 181 women: 60 exposed and 121 unexposed. Prevalence of hyperglycemia in the exposed group was 43.3% versus 27.3% in the unexposed group. After logistic regression, the relative risk was significantly higher (RR=5.7; 95% CI: 2.04-15.60) in women practicing DV (p=0.001). The second determinant significantly associated with hyperglycemia was the presence of metabolic syndrome (RR=16.5; 95% CI: 4.82-56.04; p<0.001). Conclusion: VD is a risk factor for the occurrence of hyperglycemia in our context. Key words: Voluntary depigmentation; Hyperglycemia; Diabetes; Cameroon
The specifics of discourse, mentalization and conceptualization of reality in the formation of a borderline personality
Authors: Shapoval Irina
Published: January 2023

The subject of the study is the mutual influence of discourse deformations and cognitive mechanisms of mentalization and conceptualization of the world in a borderline personality. The aim of the work is to prove the decisive role of the deficits and defects of the "theory of mind" in the development and structuring of the borderline personal organization. The research methodology is represented by interdisciplinary categorical-genetic analysis and synthesis of theories and ideas of phenomenology, cognitive psychology, clinical psychology, psychotherapy, discourse analysis. The author examines the interaction of discursive and cognitive mechanisms of personality in the construction and personalization of the conceptual sphere and "theory of mind". The role of splitting in the conceptualization of reality and the connection of violations of mentalization with changes in the concept of Self are shown. A special contribution of the author to the study of the problem is the systematization of violations of mentalization as predictors of the development of borderline personal organization. The novelty of the research lies in determining the double determination of distortions of the conceptual sphere in the borderline personality by its discourse. Violations of conceptualization processes are described. The systematic organization of the operational units of the mental lexicon, memory and the conceptual sphere in their connection with discourse is determined. The main conclusion is the proof of the relationship between stereotypical discursive formulas, mental vocabulary, methods and abilities of the subject to process information and construct the conceptual sphere. The range of the subject's capabilities in this area is manifested in his discursive formulas of interpretations, assessments, self-regulation. The deformations of these phenomena and the deep rooting of discourse in the structures of thinking correlate with the formation of a pathological "theory of mind" and personal organization. The "borderline" conceptual sphere and the discourse "speaking" by the subject hinder reflection, honest internal dialogue, criticism of representations of reality and support the status quo of the pathology of cognition of reality and orientation in it. The study of the subject's speech models and the understanding of the cognitive-discursive mechanisms of his orientation in his Self and relationships has practical significance in the diagnosis of borderline personality organization and psychocorrective effects on it.
De silencios y aperturas: reconocimiento de las victimizaciones de sectores sociales LGBTI en los modelos recientes de Justicia Transicional en Colombia
Authors: Garcés-Amaya Diana Paola
Published: January 2023

This article proposes a queer approach to analyze the emerging notions of victim in different contents and institutional developments of Colombia’s Justice and Peace Transitional Justice (2005) and Final Agreement (2016) models, which are, as yet, little explored in the field of peacebuilding studies. It analyzes the openings and conditions of possibility to name heterosexual violence and cisprivileges as constitutive of structural and armed violence, focusing on official documents in dialogue with the existing queer literature in this field of studies. The analysis considers three scenarios: the first years of implementation of the Justice and Peace Law, the lessons learned in the justice component in the application of the gender approach, and the progress in the implementation of the Final Agreement and the persistent challenges. The analysis concludes, and therein lies the originality of the article, that there is a qualitative change in the understanding of violence, which goes from being androcentric and assuming a binary interpretation to explicitly recognize LGBTI people and their quality of victims in the face of heteronormative violence, the continuum of structural, daily and armed violences, its intertwining with other power matrices, and the recognition of the different patterns that operated to correct or eliminate sexual and gender dissidence.

Background

Icaritin (ICT) has been previously demonstrated to display protective effects against cerebral ischemic reperfusion (I/R) by inhibiting oxidative stress, but the mechanism remains unclear. This study aimed to explore the mechanism from the perspective of metabolomics.

Methods

A mice cerebral artery occlusion/reperfusion (MCAO/R) model was explored to mimic cerebral ischemic reperfusion and protective effect of ICT was assessed by neurologic deficit scoring, infarct volume and brain water content. Ultra-high-performance liquid chromatography electrospray ionization orbitrap tandem mass spectrometry (UHPLC-ESI-QE-Orbitrap-MS) based metabolomic was performed to explore potential biomarkers. Brain tissue metabolic profiles were analyzed and metabolic biomarkers were identified through multivariate data analysis. The protein levels of Nrf2, HO-1 and HQO1 were assayed by western blot. The release of malondialdehyde (MDA) and the activity of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and catalase (CAT) were detected using corresponding assay kits.

Results

The results showed that after ICT treatment, the neurological deficit, cerebral infarction area, brain edema and the level of MDA in brain tissue of MCAO/R mice were significantly reduced. Meanwhile, ICT enhanced the activity of SOD, CAT and GSH-Px. Western blot results confirmed that ICT up-regulated the protein levels of antioxidant-related protein including Nrf2, HO-1 and NQO1. According to the metabolomic profiling of brain tissues, clear separations were observed among the Sham, Model and ICT groups. A total of 44 biomarkers were identified, and the identified biomarkers were mainly related to linoleic acid metabolism, arachidonic acid metabolism, alanine, aspartate and glutamate metabolism, arginine biosynthesis, arginine and proline metabolism, D-glutamine and D-glutamate metabolism, taurine and hypotaurine metabolism and purine metabolism, respectively. At the same time, the inhibitory effect of ICT on arachidonic acid and linoleic acid in brain tissue, as well as the promoting effect on taurine, GABA, NAAG, may be the key factors for the anti-neurooxidative function of mice after MCAO/R injury.

Conclusion

Our results demonstrate that ICT has benefits for MCAO/R injury, which are partially related to the suppression of oxidative stress via stimulating the Nrf2 signaling and regulating the production of arachidonic acid, linoleic acid, taurine, GABA, NAAG in brain tissue.

Published: January 2023

Surface integrity in electric discharge machining (EDM) has always been a major concern in the manufacturing industry. Although EDM with powder suspended dielectric has shown good potential in enhancing material removal rate and improving surface finish, the influence of the same on overall surface integrity is not very clear. The current work utilized (γ-Fe2O3) nano-powder and evaluated its role in combination with concentration and machining parameters, on surface roughness (Ra, Rmax), surface crack and thickness of recast layer, during powder-mixed micro-EDM (PMµEDM) of Co-Cr-Mo. SPM data are obtained through the database and its morphologies and meteorology are studied using the gwyddion software. Results showed that significant reduction in surface roughness, crack density and recast layer thickness is possible with the PMµEDM process.

Authors:   Universidad Complutense de Madrid (España), Moreno Bobadilla Ángela
Published: January 2023

El derecho al olvido digital se ha convertido en cuestión de capital importancia, debido a la ausencia de fronteras espacio-temporales de Internet. Para entender todo lo relativo al mismo, es necesario analizar cuál es su verdadero origen, previo a la sociedad digital. Por ello, en primer lugar se estudian sus orígenes que datan de finales del siglo XIX, y que se ubican principalmente en Estados Unidos y Francia. Posteriormente, se analizan las diferentes formas de protección de este derecho emergente en Estados Unidos y Europa, para poder comparar las diferentes realidades que se están dando en ambos Continentes.
El lugar de la disolución por causa grave dentro de las medidas de protección al accionista minoritario de la sociedad anónima cerrada
Authors:   Universidad de los Andes (Chile), Manterola Pablo
Published: January 2023

El trabajo analiza la disolución judicial de la sociedad anónima cerrada y la sitúa en el contexto de otros dos remedios al conflicto entre accionistas: el derecho de retiro y la indemnización de perjuicios. Se argumenta que la disolución está diseñada para que el accionista minoritario renegocie con el mayoritario, recreando con bastantes límites– las condiciones iniciales de la inversión. Sobre la base de este análisis, se describe la disolución como un mecanismo alternativo (no subsidiario) al derecho de retiro, mientras la indemnización de perjuicios sería un remedio complementario, que debe compatibilizarse con la restitución de la cuota de liquidación.
La pregunta por la normatividad del contrato: autonomía privada y reglas no contractuales
Authors:   Universidad de Chile (Chile), Berner Zúñiga Carlos , Gutiérrez Martínez Emanuel ,   Universidad de Chile (Chile)
Published: January 2023

Este trabajo incursiona en la pregunta relativa al fundamento normativo u obligatoriedad moral del contrato. Ante esta pregunta, se presentan dos puntos de vista. El primero entiende que el contrato realiza un valor en sí mismo, cuyo fundamento se encuentra en el principio de autonomía (justificación intrínseca); el segundo, que la justificación del contrato pende de la realización de un valor social por su intermedio, como un ideal de eficiencia o justicia material (justificación extrínseca). El artículo intenta una defensa de la primera posición, enfatizando que al ser un valor que se desenvuelve dentro de una práctica social compartida como es el contrato, la autonomía necesariamente coexiste con reglas heterónomas o no contractuales que, en vez de socavarla, la hacen posible.

Benthic diatoms have gained prominence as environmental bioindicators since the beginning of the twentieth century. Epilithic diatom taxa are frequently used for ecological water-quality assessments of rivers. Diversity of these dominant group of protists in the benthic communities can be indicative of changes in the freshwater ecosystem. The aim of this study was to analyze the diversity and ecology of diatoms of the Spreča River on the locations affected by urban and industrial pollution. Field sampling of the epilithic diatoms was carried out in the period of May 2021 at two locations, first before and second after the Lukavac city, which is known as industrial city in Bosnia and Herzegovina. Taxonomic verification was carried out using light microscope on permanent slides and revealed in total 38 diatom taxa. The genera with the largest number of species were Diatoma, Navicula and Nitzshia. Identified taxa are widespread species that are known for tolerating  high levels of pollution. A slightly higher number of taxa was recorded at the first location, while at the second, a higher proportion of halophilic taxa was observed.
