Theoretical and Experimental Study of Unsteady Natural Convection Heat Transfer Through Cavity Between Eccentric Horizontal Cylinders
Authors: Ahmad Omer Khalil
Published: July 2022

A theoretical and experimental study on the transient natural convection heat transfer across an eccentric horizontal annulus under the condition of constant surface temperature was carried out. The numerical study was carried out using the computational fluid dynamics code, Fluent, based on the method of control volume to study the natural convection phenomena in this enclosure. The experimental work included manufacturing an experimental setup to clarifying the effect of eccentricity ratio, angular position, and time on the natural convection inside the enclosure. Results were presented in graphic forms of streamline and temperature distribution inside fluid. The study showed that the ability of the inner cylinder on transient convection heat transfer decreased as the transient Raleigh number increased which is increase as time required to reach the steady state increase, perhaps this ability increase in the case that include eccentricity ratio (ε=0.726) in the angular position (δ=180o) where this ability will be higher than concentric state (ε=0).
Bearing Capacity of Eccentrically Loaded Strip Footing Near The Edge of Cohesive Slope
Authors: Al-Jubair Haider S. , Abbas Jawdat K.
Published: July 2022

The finite element method is used to investigate the behavior of a strip footing constructed near the edge of a sloping cohesive ground. The effects of variation in footing closeness, loading eccentricity and slope angle are studied also. It is proved that Bowles method overestimates the load carrying capacity of the concentrically loaded strip footings on cohesive soils. Decreasing the distance between the footing and the slope edge, increasing the eccentricity and slope angle reduce the ultimate bearing capacity. Slope effect diminishes as the footing distance from the edge approaches (1.5) times its width.

In this research, a numerical study has been done to done to clarify the effect of the eccentric annulus of to two horizontal cylinders on the rate flow the behavior of the thermal boundary layer at the entrance. The research includes the study of the effect of the eccentric annulus percentage and its directions on the flow behavior when the internal cylinder. The theoretical analysis of the question includes the solving of Naver – Stoke and energy equations on the supposition that the flow is steady, fully developing hydrodynamic, and in the stage of thermal developing. The question has been numerically solved after the transformation of the Cartesian coordinates to the computational domain by applying body fitted coordinates. The results include a survey of the cylinder surface in many sites of annulus flow, where as it is appeared in that the bouncy force causes the secondary flow behaves none uniformly at the entrance. The Nusselt number average along the two cylinders is decreased with the increase of eccentricity as a result of narrowing in the flow area which diminishes the average of heat transfer quality. We also conclude that the increase of Rayleih number with the movement of the heated cylinder towards low causes the increase of the average of Rayleih number and the laminar flow changes to turbulent flow at the limited region of the entrance when Rayleih number increases or the eccentricity percentage with cylinder movement away from the perpendicular halfway axis but the disturbance vanishes in approaching to the fully developed heated region. A correlation relationship is extracted to find an average change of Nusselt number after the stability of flow in the fully developed region when the diameter of the internal cylinder equals to half of external.

Published: July 2022

A theoretical study was carried out for transient heat transfer forced convection through horizontal tube filled with porous media. All the properties of the porous media are assumed to be constant in both the radial and axial directions. The governing equations are momentum and energy equation. These were formulated in using polar coordinates system. The results obtained are for three values of the effective Prandtl numbers and dimensionless pressure gradients. Theses gradient are (0.1,0.3,0.9) Pre ,(103 ,104 ,105 )B. The study proved that the thickness of the thermal boundary layer and its length depend on the parameter (B) and the effective Prandtl number. The thickness of the thermal boundary layer began with an increase starting from the front edge (inter section) until the thickness becomes equal to the radius of tube. The increase in Prandtl number gives an increase in the thickness of the thermal boundary layer for the same pressure gradient.

Published: July 2022

To define the biological features of phytoplankton in Mosul Dam Lake, monthly samples were collected along a year from September 2003 to August 2004. Consisting thermal stratification and turn over periods from four locations in the main lake and another location in the regulating lake. Total numbers of algae reached 2300 cell/ml in the main lake and 1100cell/ml in the regulating lake. Bacillariophyta were dominant with a maximum number of 1400 cell/ml in autumn. Chlorophyta were dominant in autumn also with 550 cell/ml. Ten genus of Chlorophyta were appeared in this water body: Cosmarium, Chlorella, Spirogyra, Scendesmus, Pediastrum, Tetraedron, Quadrigula, Ankiseradosm, Pandorina, and Straurastrum. Seven genus of Bacillariophyta were noticeable. Some genus of Cyanophyta was recorded as Aphanocapsa. In addition some Euglenophyta spp. were occurred in the main lake and the regulating lake also. On the basis of these algae abundance, the lake is undergoing cultural Eutrophication. It has passed in mesotrophic state (the middle trophic state of Eutrophication). Some genera which were appeared are the indication of eutrophic state. Total plate count bacteria ranged from 400-1700 cell/ ml in the main lake and 200- 950 cell/ml in the regulating lake were also recorded. Coliform bacteria were founded with most probable number reached 460 cell/100ml in the main lake and 150 cell/100ml in the regulating lake. Therefore, the lake water is classified as moderate pure and considering a good source of raw water supply with all treatment units and safe for swimming and recreational uses.

Authors: Alannaz Layth A.
Published: July 2022

The research focus on using the aeration process as means for water recarbonation after lime-soda softening. The results indicated that aeration efficient for recarbonation of three water samples with different characteristics. The lime-soda softening increased the (pH) values of the three samples to reach (10.08,10.39,10.54) respectively. The aeration decreased these (pH) values to (8.26,8.36,8.23) respectively within (60)minutes. The depression was related to the convert of the hydroxide and carbonate of the sample to the bicarbonate form by CO2 gas absorbed from the air bubbles. The absorption efficiencies were (30.9,31.0,24.7)% for the three samples respectively. The research also determined the value of (pH) at which the softened sample is saturated with calcium carbonate . These values for the three samples were (8.30,8.39,8.44) respectively. Accordingly the Langer saturation index for each sample have a positive value. The samples is at supersaturation condition with calcium carbonate for all samples. Therefore the aeration period needed to obtain the saturation state at which the sample is stable was determined to be (58.8,59.1,55.2)minutes for the three samples respectively.
Reception and vulgarization of Roman law by barbaric legislation on the example of the Edict of Theodoric (VI century)
Authors: Makutchev Aleksandr Valer'evich
Published: July 2022

The subject of the study was the reception (borrowing) of the norms of Roman law by the legislation of barbarian states that gained independence after the fall of the Western Roman Empire, as well as the accompanying vulgarization (simplification) of legal norms. The object of the study was the Edict of Theodoric - a collection of legal norms of the VI century, adopted on the territory of Italy on the initiative of the Ostrogothic ruler Theodoric the Great. This document was aimed at ensuring the peaceful coexistence of the Gothic and Roman populations of Italy, which is why it demonstrates the mechanism for including the norms of Roman law familiar to a significant part of the population into a single system of legislation of the barbarian Ostrogothic Kingdom. The main research methods were comparative legal and historical. The main conclusions of the study are the following: 1) the reception of Roman law by barbaric legislation, on the example of the Edict of Theodoric, took place in three directions - the expansion of the original norm, its narrowing and qualitative reinterpretation; 2) vulgarization was an integral part of the reception, but one should not perceive the process of simplifying the norms of Roman law as exclusively negative, vulgarization was one of the mechanisms that ensured the survival of Roman law and the subsequent revival in the legal systems of continental Europe. The novelty of the research is based on the use of comparative legal and historical methods: they allowed to identify the main sources of the Theodoric Edict, compare the provisions of the original norms with their interpretation in the text of the Edict, identify the reasons for verbatim borrowing or rethinking of specific norms.
Geographical approach to determining access to justice in criminal cases (on the example of district courts of the Kurgan region)
Authors: Abdulvaliev Almaz Firzyarovich
Published: July 2022

The purpose of this study is to test the extent to which courts of general jurisdiction in some regions of the Russian Federation are accessible to the population from a geographical point of view. The object of the study was the district courts of general jurisdiction located in the district centers of the Kurgan region, and their remoteness from the locations of local governments, law enforcement agencies, airports, bus stations and railway stations. The main research methods were the geoinformation method, the cartographic method, as well as the comparative legal method, including the analysis of the norms of the criminal procedure legislation of the Russian Federation and judicial practice. The application of the geographical approach made it possible to establish in various aspects how accessible the courts of general jurisdiction are to the population living in various municipal districts of the Kurgan region.   The conducted research revealed a number of problems related to ensuring access to justice for the local population. Despite the fact that most of the district courts of general jurisdiction in municipal districts are located within walking distance from local self-government and law enforcement bodies nearby in the district center and have good transport links with bus stations, railway stations and air terminals, yet 1/10 of the district courts remain inaccessible to the population due to remoteness and lack of good and permanent transport communication. In addition, the underdeveloped air communication of the Kurgan region with other regions of Russia does not contribute to ensuring high-quality access to justice.

Published: July 2022

The subject of the research is the ways of using modern Big Data and Data Mining methodologies to improve the process of lawmaking and law enforcement practice in the field of illicit trafficking of new psychoactive substances. Based on the experience of European countries and international experience in general, the author proves the need to create a methodology for early detection of the spread of new psychoactive substances that pose a significant threat to public health. This technique, according to the author, can be based on the use of methods of applied statistical analysis of the Google Trends database, which, in turn, can be used to combat drug crime in terms of detecting and predicting crimes. The practical significance of the conducted research lies in the development of a methodology for early detection of the spread of new psychoactive substances, which can be used to optimize the operational legislative response and improve law enforcement practice in the field of combating illicit drug trafficking. The scientific novelty of the conducted research consists in the creation of a predictive rule in the form of a linear regression equation that allows predicting the spread of such a new psychoactive substance as mephedrone in various regions of the Russian Federation, as well as planning operational investigative measures taking into account the identified risk zones. This study may be of interest to law enforcement officials, legal scholars, students and teachers of law schools.
The work of the first laboratories of experimental psychology in the key of the pedagogical community at the beginning of the 20th century.
Authors: Kreitsberga Karina Andrisovna
Published: July 2022

The subject of the study is the origin of the first experimental laboratories and their interaction with the pedagogical community. The emphasis is placed on the prerequisites and controversial points of this cooperation, which will become the basis for pedological experiments in the 20s, and the legal functioning of the new, at that time, research space is also taken into account. The object of the study is pedology as a new scientific direction. The author examines in detail such aspects of the topic as socio-economic prerequisites, formation and scientific potential of pedological experiments. Particular attention is paid to specific representatives, their professional activities, and the assessment of a new direction in the pre-revolutionary space of the Russian Empire. The main conclusions of the study are: identification of the "artificiality" of the new trend, generalization of the experience gained, analysis of the assessment of the first successes of the laboratories, the significance of the work of the first pedological laboratory of A. P. Nechaev in St. Petersburg, comparison of the general course of development of the experimental science of pedology with European analogues. A special contribution of the author to the study of the topic is the reconstruction of the mental space of interaction between teachers and leading specialists in the field of pedological experiments, involving archival documents of the Central State Administration of St. Petersburg regarding the history of the first pedological studio in St. Petersburg. The study attempts to trace the scientific path of the dissemination of pedagogical ideas of the new paradigm. The novelty of the study is to identify real changes in the pedagogical community of the early 20th century.

Authors: Duong Vicky , Dennis Simone , Ferreira Manuela L. , Heller Gillian , Nicolson Philippa J.A. , Robbins Sarah R. , Wang Xia , Hunter David J.
Published: July 2022

Objective

To explore the person-level predictors of adherence to a step count intervention following total knee replacement (TKR).

Design

Prospective cohort study, nested within the PATHway trial.

Methods

Participants who had recently undergone TKR were recruited from 3 rehabilitation hospitals in Sydney, Australia, for the main trial. Only data from participants who were randomized to the TKR intervention group were analyzed. Participants in the intervention group (n = 51) received a wearable tracker to monitor the number of steps taken per day. Step count adherence was objectively measured at 3 months as the number of steps completed divided by the number prescribed and multiplied by 100 to express adherence as a percentage. Participants were classified into 4 groups: withdrawal, low adherence (0%–79%), adherent (80%–100%), and >100% adherent. Ordinal logistic regression was used to identify which factors predicted adherence to the prescribed step count.

Results

Of the 51 participants enrolled, nine (18% of 51) withdrew from the study before 3 months. Half of participants were classified as >100% adherent (n = 24%, 47%). Ten were classified as low adherence (20%), and 8 participants were classified as adherent (16%). In the univariable model, lower age (OR 0.90; 95% CI 0.83–0.97), higher patient activation (OR 1.03; 95% CI 1.00–1.06), and higher technology self-efficacy (OR 1.03; 95% CI 1.00–1.06) were associated with higher adherence. After adjusting for age in the multivariable model, patient activation and technology self-efficacy were not significant.

Conclusion

Younger age, higher patient activation, and higher technology self-efficacy were associated with higher adherence to a step count intervention following TKR in the univariable model. Patient activation and technology self-efficacy were not associated with higher adherence following adjustment for age. J Orthop Sports Phys Ther 2022;52(9):620–629.

Reparation for Victims of Serious Human Rights Violations during Armed Conflicts: Focus on the Case of Bosnia-Herzegovina
Authors:   Korea International Law Review, Song Esther
Published: July 2022

Historically, Bosnia-Herzegovina (hereafter “Bosnia”) has been a region where diverse ethnic groups, cultures, and religions coexisted. However, in the process of the dissolution of the Socialist Federal Republic of Yugoslavia in the early 1990s, armed conflicts broke out between ethnic groups in Bosnia, and mass atrocities were experienced. Although the Dayton Peace Agreement—led by the United States—was signed by the parties involved in the conflict in November 1995, thus ending the war in Bosnia, large and small conflicts continued. Accordingly, extensive efforts are still needed to heal the wounds from war and settle peace through reconciliation. Since the end of the war, Bosnia has focused on the punishment of war criminals through the International Criminal Tribunal for the former Yugoslavia (ICTY), and many studies have been conducted in this regard. However, research on reparation for victims of these war crimes has been relatively limited. Thus, this paper examines and evaluates the efforts that have been made at the international and domestic levels to compensate the victims of the Bosnian War. At the international level, such compensation was first attempted by the ICTY but was ineffective, as it was entrusted to the domestic courts. Afterward, in the Genocide Convention Case before the International Court of Justice (ICJ), Bosnia sought reparation from Serbia by invoking state responsibility. However, in its 2007 judgment, although the ICJ confirmed Serbia’s violation of the obligation to prevent and punish genocide, it refused to give an order for compensation because a sufficient and direct causal link could not be found between the violation and damages. Thus, the declaration on Serbia’s failure to prevent and punish the genocide was to be considered appropriate satisfaction. At the Bosnian national level, the victims sought compensation through the domestic court and Human Rights Court, but this too had several limitations. The victims also argued for compensation in the Netherlands, but the Dutch Supreme Court only recognized a 10% liability of the Dutch government for the deportation of refugees from the UN military compound, which was carried out by the Dutch UN forces. In conclusion, many Bosnian War victims have not yet received adequate reparation, almost 30 years after the end of the war. Therefore, it is critical to establish a comprehensive reparation program for all the victims as soon as possible.

Published: July 2022

O livro do Deuteronômio é um projeto pedagógico, preocupado com a formação das futuras gerações dos filhos de Israel, nascidas no deserto que não fizeram a experiência da aliança estabelecida no monte Sinai. Desse modo, Moisés, nas estepes de Moab, oferece ao novo Israel a possibilidade da renovação desta aliança, que, se observada, permitirá que o novo Israel possa entrar, possuir e permanecer na terra que YHWH lhe dará: uma terra com poços, vinhas e oliveiras. À luz desse acontecimento, o presente artigo tem como objetivo desenvolver, a partir do antiquíssimo método de leitura da Sagrada Escritura, denominado Leitura Orante da Bíblia, a análise de Dt 6,1-13 estruturada em: introdução; ambientação da temática; texto segmentado; contexto literário e resposta para quatro perguntas: que diz o texto ao ouvinte-leitor? Que propostas o texto faz ao ouvinte-leitor? O que o texto possibilita ao ouvinte-leitor dizer a Deus em oração? Que decisões o texto leva o ouvinte-leitor a tomar? Algumas considerações finais encerram a análise.

Published: July 2022

Background:

Congenital muscular torticollis (CMT) is a common musculoskeletal anomaly that can be excellently managed at birth with conservative physiotherapy; as a result, literature on neglected cases of CMT in older patients is sparse, and there is controversy regarding the ideal surgical approach. This report aims to provide the outcome of 28 adolescent patients with neglected CMT who underwent unipolar release at the distal sternocleidomastoid muscle (SCM).

Methods:

Twenty-eight adolescent patients with untreated CMT presented to our department between 2016 and 2019 and underwent unipolar release at the distal end of their SCM. All patients had no other anomaly based on clinical examination and radiological investigations. At the time of surgery, the mean age of patients was 15.8 years (range 13–18 years). There were 10 male and 18 female patients with the right side affected in 20 cases. All patients were followed up for 2 years. Patients were evaluated using an adapted version of the modified Lee’s scoring system to assess cosmesis and the cervical-mandibular angle (CMA) to assess radiological change.

Results:

The adapted modified Lee’s scoring system indicated 17 patients (60.7%) had an excellent outcome, 6 patients (21.4%) had a good outcome, and 5 patients (17.9%) had a fair outcome. In particular, scarring was fine in 23 patients (82.1%) and only slight in the remaining. Independent to the categorical outcome, all patients subjectively reported high satisfaction with their cosmesis. The preoperative mean CMA was 19.6° (range, 8.5–31.5°), which was reduced to a mean of CMA of 14.0° (range, 3–28°) after surgery (P < 0.05). No patient developed any permanent complication or required surgery for recurrence. No serious postoperative complications such as infection or hematoma were observed.

Conclusion:

In uncomplicated cases of neglected CMT in adolescent patients, unipolar tenotomy of the distal SCM is a safe and reliable technique with good clinical outcomes.
Modified retrosigmoid extended approach to jugular tubercle meningioma: A video abstract
Authors: Hawsawi Aysha Hamzah , Bawazir Minyal , Basindwah Sarah A. , Alqurashi Ashwag , Ajlan Abdulrazag
Published: July 2022

Background:

Primary jugular fossa meningiomas are one of the rarest subgroups of meningioma, with an estimated incidence of 0.7–4.3% of all skull base meningiomas. Indeed, only 145 cases of jugular foramen meningiomas have been reported in the literature to date. While meningiomas of this region are typically referred to as “jugular foramen meningiomas,” we make a distinction between meningiomas arising directly from the foramen itself, and those arising from the jugular tubercle. Jugular tubercle meningiomas, therefore, represent an even smaller subset of an already uncommon location for meningiomas. The jugular tubercle is the upper surface of the lateral parts of occipital bone presents an oval eminence, which overlies the hypoglossal canal and is sometimes crossed by an oblique groove for the glossopharyngeal, vagus, and accessory nerves. Only eight cases in the anterior foramen magnum lesions excised by a far lateral retrosigmoid approach have been described. The aim of this video article is to describe the surgical approach the senior author used to access lesion involving the jugular tubercle.

Case Description:

In this surgical video, we present a case of a 56-year-old female presented to our hospital with dizziness, headache, lower cranial nerves deficits, and lower limbs weakness. On exam, she was noted to have a left paraparesis, 9th, 10th, and 11th nerves palsies. An MRI scan demonstrated a mass in the region of the left jugular tubercle. Frozen section was suggestive of meningioma and our patient underwent a successful near total resection with no permanent neurologic sequelae.

Conclusion:

Jugular tubercle meningiomas are one of the rarest subgroups of meningioma. The described modified retrosigmoid approach provides outstanding access to the entire ventrolateral brainstem and cerebellopontine angle, with reduced approach related morbidity.

Authors: Tirado-Ornelas Héctor Alonso , Olivares-Peña Jorge Luis , Olivares-Camacho Jorge Luis , Santos-Franco Jorge Arturo , Ochoa-González Maurilio Vicente
Published: July 2022

Background:

Hemangioblastomas are benign tumors that develop in the central nervous system. They represent 1.5–2.5% of all intracranial tumors, and about 2–15% of all spinal cord tumors. They are highly associated with von Hippel–Lindau disease.

Case Description:

A 36-year-old female presented with a 4-year history of progressive right upper extremity distal weakness and cervical pain. The magnetic resonance imaging demonstrated a homogeneously, contrast enhancing intradural/intramedullary tumor at C6–C7 with perilesional edema and a syrinx accompanied by a cerebellar cyst with a mural nodule. Surgery included excision of the spinal lesion and decompression and excision of the cerebellar cyst and mural nodule (i.e., median suboccipital craniectomy and cervical C5–C7 laminectomy).

Conclusion:

Surgery is the gold standard treatment for symptomatic hemangioblastomas, and surgical approaches should minimize risk.

Background:

Systemic anticoagulation has been the standard treatment for cerebral venous sinus thrombosis (CVT). Although endovascular treatments, including mechanical thrombectomy (MT), have been reported to be effective for CVT, no clear evidence has been established.

Case Description:

A 51-year-old woman who had been administered oral contraceptive pills was transferred to our hospital with altered consciousness and disorientation. Computed tomography (CT) revealed a hyperdense signal in the straight sinus (StS), and CT angiography revealed a defect in the basal vein and StS, leading to a diagnosis of StS thrombosis. Although systemic anticoagulation through unfractionated heparin was performed, her neurological condition deteriorated, and venous ischemia was observed on CT the next day. She then underwent MT. Partial recanalization was achieved with an aspiration catheter and a stent retriever. Her neurological condition improved tremendously, and venous ischemia was reversed following MT. She was discharged 3 weeks later without neurological deficits with oral anticoagulant.

Conclusion:

This was a relatively rare case with CVT confined to StS. Immediate combined MT for StS thrombosis can improve venous circulation, make the venous ischemia reversible, and improve patient outcomes, even if it results in partial recanalization.

Langage, pensée et signification
Authors: Mahmoudian Mortéza
Published: July 2022

De nombreuses études ont été consacrées aux rapports entre langage et pensée. Traditionnellement, le rapport entre langage/pensée est considéré sous un seul angle : celui des unités significatives (mots) et catégories de pensée (choses). Ainsi, restent hors jeux toutes les opérations mentales qui sous-tendent l’acquisition et le maniement des sous-systèmes, dont la phonologie, la morphologie. Par ailleurs, la question est posée de la façon suivante : y a-t-il une relation de détermination entre les deux phénomènes ? Dans l’affirmative, est-ce le langage qui détermine la pensée ou au contraire, est-il déterminé par elle? En abordant le problème de cette façon, on part — me semble-t-il — de certains postulats : l’homogénéité et du langage et de la pensée ; la simplicité de leurs rapports et l’identité de la pensée à ce qui est exprimé par le langage (autrement dit, la signification linguistique). La remise en question de ces postulats conduit à concevoir langage et pensée comme des phénomènes entretenant des rapports complexes : variés et hiérarchisés."

Published: July 2022

Résumé : La philosophie religieuse russe a connu un développement spécifique au tournant du XIXe et du XXe siècle. A cette époque elle a intégré d'une manière originale les idées de Platon, d’Hegel et la spécificité de la culture et de la religion orthodoxe russe, en donnant naissance à de nombreux travaux consacrés à la philosophie du langage et du nom.Dans cet article il s'agit essentiellement de la conception onomatologique d'Aleksej Losev (1893-1988), philosophe et penseur religieux russe, traducteur de la littérature du Moyen Âge, dont la philosophie du langage et du nom est un phénomène considérable de la vie intellectuelle et spirituelle de la Russie du XXe siècle.A la base de la philosophie du langage de Losev repose l'étude de l'onomatodoxie, étude spirituelle sur le Nom de Dieu. La compréhension de la nature divine dépasse le cadre étroitement orthodoxe et religieux.

Cet article étudie les continuités qui se font jour, souvent cachées par des changements politiques dramatiques,  sur la scène de la philosophie et de la pensée sociale pendant la période soviétique, depuis la Révolution d’Octobre en 1917 jusqu’à la désintégration de l’URSS en 1991. Comme le paradigme intellectuel dominant de toute cette période était le marxisme, toute réflexion sérieuse sur la question de la continuité doit non seulement prendre en compte le marxisme, mais encore le mettre au centre de l’attention. C’est ce dont traite la première partie de l’article. Dans cette optique, la continuité inscrite dans la dialectique permanence / transformation avait deux aspects importants : l’auto-conscience et le positionnement du marxisme soviétique par rapport à la philosophie occidentale non- marxiste, et, au-delà, mais aussi indépendamment, à la pensée russe d’avant 1917.La seconde partie de l’article examine différents discours de l’exceptionnalisme, essentiellement la renaissance du slavophilisme, du počvenničestvo et de l’eurasisme. L’accent est mis sur l’Union Soviétique et non sur l’émigration, car cela aurait reproduit l’idée erronée que les intellectuels émigrés sont les seuls hérities authentiques de la tradition prérévolutionnaire.
Vl. Soloviev, Descartes, Kant. Substances, spectres et formes dans leurs conceptions du je1
Authors: Molchanov Victor
Published: July 2022

Dans son ouvrage tardif, plus précisément, dans ses trois articles réunis sous le titre de «Philosophie théorique», V. Soloviev tente de justifier aussi bien la nécessité du principe impersonnel en philosophie, que la «quête de la vérité», tout aussi impersonnelle. Il refuse la position substantialiste du je à laquelle il adhérait auparavant, et s’efforce de prouver que le sujet, ou le je, n’est pas donné en tant que substance dans la conscience immédiate, mais comme une forme renfermant «le matériau psychique de chaque individualité». Si l’on admet que Soloviev a évolué du substantialisme au phé- noménalisme, il faudra alors tenir compte du caractère particulier de ce dernier : est donné, selon lui, un réceptacle (forme), ou un canal à travers lequel coule le flux de l’existence psychique.La position de Soloviev est déterminée non seulement dans ses prémisses, mais aussi dans sa finalité. Celle-ci est l’«omni-totalité» (vse- cel’nost’) de la vérité en tant que processus supra-personnel, ce qui présuppose un «je vide» et une «conscience de personne». Soloviev adopte ainsi une stratégie de transition entre la certitude immédiate des «faits de pen- sée» et la «conscience de personne». Cette stratégie présuppose la critique du substantialisme du je : il tente de présenter le je, d’abord, comme un fait secondaire parmi d’autres actes psychiques (Soloviev n’est pas toujours au clair quant aux rapports entre actes et faits), puis, comme un fait phénoménologique et, en même temps, comme une forme vide. Ainsi, le sujet en tant que «fait phénoménologique» n’est qu’une étape passagère en la critique de la substance et le concept de la forme vide et remplissable.
Wave energy on the Veracruz Coast, Mexico. A Geologist-Geomorphological Evaluation of Ideal Sites for an Engineering Prototypes

This work aims to collect a review of the advances and governmental, scientific, technological and business challenges in the field of the use of wave energy, traveling through more than two dozen countries. Given the coastal extension of Mexico, the coasts of the state of Veracruz were selected to identify those localities with wave energy concentration due to evidence of abrasive forms in the coastal relief. Geological-geotechnical surveys were carried out in Barra de Cazones, Miradores, Villa Rica tombolo, Punta Roca Partida, Playa Hermosa, Montepío and Balzapote, as well as assessments of vulnerability to different geological-geomorphological processes. Accompanying these studies are the morphological-morphometric characterizations of the relief, the morphogenetic surveys of the sites and their surroundings, the indicative evaluation of the genesis and geomorphic intensity of the modeling of the relief, the morphodynamics of the coastline during 44 years (1973-2017) and the proposal of a coastal vulnerability index for the coasts of the Actopan municipality. Finally, an interpretation of Google Earth satellite images facilitated the recognition of 147 locations with potential for wave energy converter sites in Mexico: Veracruz (7), Quintana Roo (2), Oaxaca (22), Guerrero (15 ), Michoacán (12), Colima (4), Jalisco (15), Nayarit (6), Sinaloa (3), Sonora (5), Baja California Sur (20) and Baja California (36); All these localities are home to small coastal towns as heirs to the conversion of wave energy to electricity.

En el año 2019, el sector camaronero incrementó el porcentaje de sus exportaciones convirtiéndolo en uno de los más importantes del país y uno de los principales que podría utilizar el incentivo reinversión de utilidades. El objetivo de esta investigación fue analizar la reinversión de utilidades y su efecto en el pago del Impuesto a la Renta de la provincia de Santa Elena entre los años 2016 al 2020. En la metodología se utilizó un enfoque cuantitativo cuasi – experimental, de tipo descriptivo-exploratorio; al ser retrospectivo, se utilizó bases de datos secundarias, publicadas por el Servicio de Rentas Internas y la Superintendencia de Compañías. Los resultados muestran que este sector, al reinvertir del 1,3% al 3,8% de su utilidad, favorecería un ahorro fiscal del 32,6% al 53,2% en el pago de Impuesto; este análisis describe los posibles beneficios de este tipo de estímulos que el gobierno otorga al sector camaronero.
Organelle-selective membrane labeling through PLD-mediated transphosphatidylation
Authors: Chiu Din-Chi , Baskin Jeremy M.
Published: July 2022

The specialized functions of eukaryotic organelles have motivated chemical approaches for their selective tagging and visualization. Here we develop non-genetically encoded tools using metabolic labeling of abundant membrane lipids for selective visualization of organelle compartments. Synthetic choline analogs with three N-methyl substituents replaced with 2-azidoethyl and additional alkyl groups enabled generation of corresponding analogs of phosphatidylcholine, a ubiquitous and abundant membrane phospholipid. Subsequent click chemistry tagging with a single cyclooctyne-fluorophore reagent enabled differential labeling of the endoplasmic reticulum, the Golgi complex, mitochondria, and lysosomes depending upon the substitution pattern at the choline ammonium center. Key to the success of this strategy were the harnessing of both the organic cation transporter OCT1 to enable cytosolic delivery of these cationic metabolic probes and endogenous phospholipase D enzymes for rapid, one-step metabolic conversion of the choline analogs to the desired lipid products. The remarkably stable localizations of these azidolipids, even after fluorophore conjugation, suggests their application not only for organelle-selective imaging but also for local modulation of physiological events with organelle-level precision by tethering of bioactive small molecules, via click chemistry, within defined subcellular membrane environments.
Trade-off between redox potential and strength of electrochemical CO2 capture in quinones

Published: July 2022

Electrochemical carbon dioxide capture has recently emerged as a promising alternative approach to conventional energy-intensive carbon capture methods. A common electrochemical capture approach is to employ redox-active molecules such as quinones. Upon electrochemical reduction, quinones become activated for the capture of CO2 through a chemical reaction. A key disadvantage of this method is the possibility of side-reactions with oxygen, which is present in almost all gas mixtures of interest for carbon capture. This issue can potentially be mitigated by fine-tuning redox potentials through the introduction of electron-withdrawing groups on the quinone ring. In this article, we investigate the thermodynamics of the electron transfer and chemical steps of CO2 capture in different quinone derivatives with a range of substituents. By combining density functional theory calculations and cyclic voltammetry experiments, we support a previously described trade-off between redox potentials and the strength of CO2 capture. We show that redox potentials can readily be tuned to more positive values to impart stability to oxygen, but as a consequence, significant decreases in CO2 binding free energies are observed. Our calculations support this effect for a large series of anthraquinones and benzoquinones, with different trade-off relationships observed for the two classes of molecules. These trade-offs must be taken into consideration for the design of improved redox-active molecules for electrochemical CO2 capture.
