¿Fenêtre en longueur, hueco rasgado de suelo a techo o muro cortina? Una revisión crítica de la sintaxis del hueco en la modernidad
Authors: Marcos Carlos L.
Published: December 2021

Le Corbusier planteó durante los años 20 del siglo pasado una gramática para el nuevo lenguaje de la arquitectura de hormigón armado y acero, la arquitectura moderna. Sus míticas viviendas realizadas durante esa década en colaboración con Pierre Jeanneret constituirían un elenco extraordinariamente influyente en los años posteriores y servirían de modelos para ilustrar una teoría que vería la luz en forma de texto en 1926 a modo de manifiesto fundacional, “Los 5 puntos de la arquitectura”. Su fenêtre en longueur  –ventana rasgada horizontalmente– ponía de manifiesto la condición no portante de la fachada al tiempo que se apropiaba del horizonte y de una visión continua desde el interior. La arquitectura neoplasticista, sin embargo, directamente influenciada por la “destrucción orgánica de la caja” de Wright, planteaba rasgar huecos de suelo a techo. Ambas negaban la idea de perforar la fachada recortando los huecos sobre ella. Mies van der Rohe, el más riguroso en el detalle arquitectónico y la construcción de los arquitectos modernos, plantearía ya desde su proyecto para el rascacielos de la Friedrichstrasse de 1919 la incipiente idea del muro cortina que años después llegaría a materializar. En las siguientes líneas planteamos una discusión crítica acerca de la gramática de la modernidad y en particular respecto de la sintaxis del hueco.

O Papel do Jornalismo Impresso na Ficção: Função Social da Gazeta de Tambury na Série After Life da Netflix
Authors: Teixeira Juliana Fernandes , Martins Allysson Viana
Published: December 2021

Este artigo investiga a função social do jornalismo por meio da Gazeta de Tambury, representação ficcional de um veículo impresso local e gratuito, numa pequena cidade do Reino Unido, na série After Life, com produção e veiculação da Netflix. Com subtexto que aborda questões como o jornalismo como empresa e a rotina produtiva de um jornal, observamos a relação do jornalista protagonista com o modesto jornal em que trabalha, bem como a relevância do veículo para a sua comunidade e o seu público-alvo, os idosos. Além dos aspectos administrativos, profissionais e deontológicos abordados, é possível destacar um eixo mais geral problematizado pela série: o esforço individual dos profissionais para que o jornalismo se renove, sobretudo a partir da relação entre os repórteres Tony, veterano, e Sandy, novata.

Explora-se uma abordagem metodológica qualitativa, com estudos de caso escolhidos tendo como base premiações de peças jornalísticas nacionais e internacionais. Dois produtos dos meios jornalísticos Correio* e The Guardian compuseram o corpus. Entrevistas semiestruturadas com profissionais de cada peça foram realizadas. Os resultados indicam que uma epistemologia da prática do jornalismo em redes digitais que investe na imersão tem como especificidade modos de operação e uma disponibilidade dos agentes produtivos que valorizam a experiência.
Envelhecimento masculino e consumo: recorrências discursivas da andropausa na imprensa
Authors: Casadei Eliza Bachega
Published: December 2021

O objetivo do presente artigo é estudar as convocações ao consumo masculino na imprensa a partir do mapeamento das tensões discursivas presentes na definição midiática da andropausa. A partir dos pressupostos metodológicos da Análise de Discurso de Linha Francesa, iremos analisar as reportagens publicadas em veículos noticiosos brasileiros sobre a temática entre janeiro e outubro de 2020, observando as corporalidades mediadas e os discursos de consumo vinculados a esse corpo masculino envelhecido. É possível notar que, nessas matérias, o corpo andropáusico obedece aos imperativos do corpo hormonal e, portanto, são articulados discursos que borram as partilhas de gênero apenas para posteriormente restaurá-las sob o signo do consumo na reincorporação da distinção binária como fundamento do cuidado de si.
Arrebatamento comunicacional pelo sensível e desacontecimento jornalístico
Authors: Abib Tayane Aidar , Ventura Mauro
Published: December 2021

Em dialogia com as reflexões de Ciro Marcondes Filho sobre a Nova Teoria da Comunicação, este artigo busca entrecruzamentos teóricos de um tal escopo com a prática jornalística a partir da noção de desacontecimento noticioso. Enquanto estratégia de narração de fatos não-marcados, o desacontecimento dedica interesse a relatos da cotidianidade do homem ordinário, em contraponto aos tradicionais critérios de desvio e proeminência que atravessam a cobertura hegemônica, colhendo das construções de sentidos rotineiras marcas de resistência íntima e social para tessituras intersubjetivas. O presente estudo inscreve, nessa dinâmica, um horizonte possível a uma mediação jornalística sensível e de acolhimento ao Outro, nas trilhas de uma comunicação como fenômeno arrebatador.

Relationship of Exercise and Hospital Readmission After Spinal Cord Injury: A Secondary Analysis
Authors: Kubiak Stephanie , Sklar Elliot
Published: December 2021

Importance: After spinal cord injury (SCI), as many as 45% of people experience at least one hospital readmission within 1 yr. Identification of feasible low-cost interventions to reduce hospital readmissions after SCI is needed.

Objective: To explore whether a relationship exists between routine exercise and hospital readmission rates 1 yr after SCI.

Design: We conducted a secondary analysis of data from the SCIRehab Project, a prospective cohort study.

Setting: Five SCI inpatient rehabilitation facilities across the United States.

Participants: Participants were people age 12 yr and older who had sustained an SCI, were admitted to a participating inpatient rehabilitation facility, completed the 12-mo postinjury interview, and reported exercising either monthly or not at all since discharge (N = 520).

Outcomes and Measures: The SCIRehab Project conducted 12-mo post–inpatient rehabilitation discharge interviews. As part of the interviews, self-reported hospital readmissions and exercise frequencies since discharge (self-reported number of months, average days per week, and average minutes per day of exercise participation) were collected and analyzed.

Results: A χ2 analysis determined that a significant correlation (φ = −.091, p = .038) exists between monthly exercise and hospital readmissions 1 yr postinjury. Compared with those who did not exercise, participants who exercised monthly had 8.4% fewer hospital readmissions.

Conclusions and Relevance: A relationship exists between exercise and hospital readmission, but follow-up research is needed to determine whether regular exercise reduces hospital readmissions among this population.

What This Article Adds: After discharge, 44% of the participants did not exercise during the first year after injury. Identifying or implementing accessible community exercise programs is an area of opportunity for occupational therapy practitioners and future researchers to explore.

Authors: Arora Taaniya , Prabhugaonkar Neha , Subramanian Ganesh , Leake Kathy
Published: December 2021

Business users across enterprises today rely on reports and dashboards created by IT organizations to understand the dynamics of their business better and get insights into the data. In many cases, these users are underserved and do not possess the technical skillset to query the data source to get the information they need. There is a need for users to access information in the most natural way possible. AI-based Business Analysts are going to change the future of business analytics and business intelligence by providing a natural language interface between the user and data. This natural language interface can understand ambiguous questions from users, the intent and convert the same into a database query. One of the important elements of an AI-based business analyst is to interpret a natural language question. It also requires identification of key business entities within the question and relationship between them to generate insights. The Artificial Named Entity Classifier (ANEC) helps us take a huge step forward in that direction by not only identifying but also classifying entities with the help of the sequence recognising prowess of BiLSTMs.

functionality for aircraft. Highly complex software, however, cannot be exhaustively tested and only assured through a structured, process, activity, and objective-based approach. This paper studied the development processes and objectives applicable to different software levels based on RTCA/DO-178C, and identified 82 technical focus points based on each airborne software development sub-process, then created a Process Technology Coverage matrix to demonstrate the technical focuses of each process. This paper proposes an objective-oriented top-down and bottom-up sampling strategy for the four software Stage of Involvement reviews by considering the frequency and depth of involvement. Finally, this paper provides a Technology Objective Coverage matrix, which can support the reviewers to perform the efficient risk-based SOI reviews by considering the identified technical points, thus efficiently achieving confidence in the level of safety of the aircraft from the software assurance perspective.
10-Bit, 1GS/S Time-Interleaved SAR ADC
Authors: Kumar Donthula Shravan , Debnath Supravat
Published: December 2021

This paper describes the implementation of a 4-channel, 10-bit, 1 GS/s time-interleaved analog to digital converter (TI-ADC) in 65nm CMOS technology. Each channel consists of interleaved T/H and ADC array operating at 250 MS/s, with each ADC array containing 14 timeinterleaved sub-ADCs. This configuration provides high sampling rate even though each subADC works at a moderate sampling rate. We have selected 10-bit successive approximation ADC (SAR ADC) as a sub-ADC, since this architecture is most suitable for low power and medium resolution. SAR ADC works on binary search algorithm, since it resolves 1-bit at a time. The target sampling rate was 20 MS/s in this design, however the sampling rate achieved is 15 MS/s. As a result, the 10-bit SAR ADC operates at 15 MS/s with power consumption of 560 μW at 1.2 V supply and achieves SNDR of 57 dB (i.e. ENOB 9.2 bits) near nyquist rate input. The resulting Figure of Merit (FoM) is 63.5 fJ/step. The achieved DNL and INL is +0.85\-0.9 LSB and +1\-1.1 LSB respectively. The 10-bit SAR ADC occupies an active area of 300 μm × 440 μm. The functionality of single channel TI-SAR ADC has been verified by simulation with input signal frequency of 33.2 MHz and clock frequency of 250 MHz. The desired SNDR of 59.3 dB has been achieved with power consumption of 11.6 mW. This results in a FoM value of 60 fJ/step.
A Fair Allocation Algorithm for Predictive Police Patrolling
Authors: Rodas Arango Isabella , Dulce Rubio Mateo , J. Riascos Villegas Alvaro
Published: December 2021

We address the tradeoff of developing good predictive models for police allocation vs. optimally deploying police officers over a city in a way that does not imply an unfair allocation of resources. We modify the fair allocation algorithm of [1] to tackle a real world problem: crime in the city of Bogota, Colombia. Our approach allows for more sophisticated prediction models and we ´ show that the whole methodology outperforms the current police allocating mechanism in the city. Results show that even with a simple model such as a Kernel Density Estimation of crime, one can have much better prediction than the current police model and, at the same time, mitigate fairness concerns. Although we can not provide general performance guarantees, our results apply to a real life problem and should be seriously considered by policy makers.

Published: December 2021

Este trabajo descriptivo con un enfoque cualitativo tiene por objetivo el análisis de la norma constitucional en relación con la sentencia de la Corte Constitucional Número 34-19-IN/21. El estudio está sustentado en los métodos exegético, análisis documental y revisión bibliográfica. Después de una exhaustiva revisión de artículos científicos, libros, sentencias de la Corte Constitucional y diferentes textos académicos se concluye que el aborto por violación en el Ecuador se encontraba penalizado en el artículo 150 del Código Orgánico Integral Penal, pues el legislador establece que los únicos casos en los cuales el aborto no es punible son aquellos en que se encuentre en grave riesgo la vida de la mujer o es víctima de violación y cuente con una discapacidad mental; en caso contrario seguirá estando sujeta a una pena privativa de libertad. La sentencia No. 34-19-IN/21 es un precedente que evidencia la ausencia de proporcionalidad entre el delito de aborto por violación y la pena establecida evidenciando la poca empatía y falta de entendimiento de los legisladores y la sociedad.

Published: December 2021

A pobreza é um flagelo que afecta o mundo inteiro, agravando grupos vulneráveis ​​como as mulheres. O objectivo deste trabalho é analisar as características da pobreza em famílias monoparentais chefiadas por mulheres; Para o qual foi desenvolvido um estudo descritivo, apoiado nos métodos: revisão bibliográfica, análise documental, hermenêutica, histórico-lógica e estatística. Entre os principais achados está o fenómeno da pobreza mediado por critérios de género, o número de mulheres pobres é maior que o de homens e há uma tendência de aumento, principalmente relacionada ao aumento de domicílios chefiados por mulheres. No contexto angolano, a magnitude e intensidade da feminização da pobreza aumentam a polarização social extrema. As estratégias para solucionar esse fenómeno, embora tenham se mostrado flexíveis e adaptáveis ​​às condições existentes, privilegiam os problemas materiais e a sobrevivência imediata, sem se aprofundar suficientemente em suas causas. Os projectos familiares, quando existem, têm baixo grau de estruturação e elaboração, têm perspectiva de curto prazo e expressam demandas assistenciais com baixo nível de demanda, ao invés de aspirações futuras.
Arctic: A Rreimagined Strategic Resource Base for Russia
Authors: Ahmad Shaheer , Zafar Mohammad Ali
Published: December 2021

Russia’s Arctic ambitions are gaining attention as global warming provides Russia with an opportunity to access the untapped energy reservoirs lying in the seabed of the Arctic. Russia’s new Arctic strategy aims to utilize the Arctic as a ‘strategic resource base’ to fulfill its socio-economic needs. Moreover, the interrelated projects of Yamal LNG and the opening of the Northern Sea Route as a global shipping route show the Russian interplay of geo-economics and geopolitics. Similarly, the Russian strategies of the Northern Fleet’s revival, Sino-Russian cooperation, regional diplomacy, informational campaigns, and international law show Russia’s efforts to highlight its ambitions in the region. This paper argues that the melting ice in the Arctic coupled with evolving regional dynamics will enhance the Kremlin’s position in the region.
Features of the optical medium of the surface of plant seeds
Authors: Zienko Stanislav , Belyakov Mikhail
Published: December 2021

It was found that the integumentary tissue of plant seeds has the property of enhancing luminescence light. This phenomenon manifests itself in both the time and frequency domain.

The gain factor (in power), depending on the type of seed, varies from 1.7 (beans) to 2.6 (rye). To determine it, the optical medium of the plant seed surface was represented as a dynamic link having an input and output. The impulse (time) characteristic of the link was found by the relaxation curve of luminescence. The dependence of the gain on temperature is expressed in the fact that when it decreases from 50 oC to –30 oC, the gain increases from 1.73 to 2.48.

This phenomenon can be explained by the fact that at the stage of relaxation of luminescence, the absorption coefficient of the optical medium of the seed surface takes a negative value

Application of the optoacoustic effect to measure glucose concentration
Authors: Kravchuk Denis
Published: December 2021

Currently, there are only two invasive methods available for measuring blood glucose: the first, the most common method, requires blood to be drawn, which is then transported and analyzed to a clinical laboratory, applying the blood to a glucometer test strip. Sampling blood, especially in children, is a rather complicated process, in addition, the results of clinical trials take time. Therefore, non-invasive, continuous monitoring of glucose by optoacoustic method is quite promising. We used an optoacoustic method with a high spatial resolution, which makes it possible to measure the concentration of glucose in the blood. Experimental measurements were carried out in porcine blood at various glucose concentrations
Measuring complex for determining the characteristics
of high-voltage silicon carbide Schottky diodes in impulse modes
Authors: Zotin Vitaliy , Drakin Alexander , Rybalka Sergei , Demidov Andrey , Kulchenkov Evgeniy
Published: December 2021

This paper describes a developed automated research measuring complex that allows one to determine the parameters of currents, voltages and power of silicon carbide Schottky diodes when applied reverse voltage impulses with amplitudes from 400 to 1000 V. The research

measuring complex was tested on DDSH411A91 («GRUPPA KREMNY EL») and C3D1P7060Q (Cree/Wolfspeed) silicon carbide Schottky diodes and allows to determine their

maximum values of the rate of rise of reverse voltage dV/dt (877 V/ns and 683 V/ns). Also, the maximum values of the current rise rate dI/dt were determined for DDSH411A91 (3.24 A/ns)

and C3D1P7060Q (3.72 A/ns) diodes. For the first time it was established that, when a reverse voltage impulse with an amplitude of 1000 V is applied, the maximum values of instantaneous fullpower reach 1419 VA for the DDSH411A91 diode and 1638 VA for the C3D1P7060Q diode.
Ultra-weak emission and microcurrents instabilities in blue GaN LEDs at different stages of degradation
Authors: Ekhanin Sergei , Tomashevich Alexander
Published: December 2021

It is found that the ultra-weak luminescence observed in microcurrents mode in blue GaN LEDs with multiple quantum wells is due to tunnel-recombination processes with the participation of defect states and local potential wells of various depths, which arise as a result of

planar fluctuations of indium in the InGaN layers of the active region. Digital photographs were obtained and patterns of ultra-weak luminescence of the surface of LED crystals were analyzed. It is shown that the patterns of luminescence, along with the current-voltage characteristic, demonstrate significant changes after testing even at the initial stages of degradation, which indicates a high sensitivity of these parameters to degradation processes and the possibility of their use in diagnostic and non-destructive testing methods.
Modeling of thermal processes in the contact zones of fuel elements
Authors: Kondratenko Vladimir , Kadomkin Victor , Tretiyakova Olga
Published: December 2021

In this work, using two specific examples, a general approach to the mathematical modeling of thermal processes in the contact zones of fuel elements in the development and optimization of

various technological processes, systems and devices is considered. In the first example, a mathematical model of heat transfer in the contact zone (metal-hybrid thermal interface) between the heat-generating element and the heat-dissipating radiator is considered. In the second case, the thermal process in the processing of materials with a bonded diamond tool in the contact zone "diamond grain – binder – processed material" is considered and analyzed. The general approach to modeling thermal processes in the contact zones of various fuel elements makes it possible to optimize the parameters of technological processing modes and the correct operating conditions for products and systems

The influence of stress factors on the plant can lead to deterioration of plant functioning and loss of yield. The use of biological preparations based on plant cell elicitors in the technology of grain cultivation makes it possible to regulate the antioxidant activity of plants under abiotic stress. Treatment with the biopreparation Nigor++ in the tillering phase leads to noticeable changes in the balance of antioxidant substances in winter wheat plants Moskovskaya 39. Repeated treatment of Nigor++ after 16 days in the earing phase reduces AOA by 21.8, and by the flowering phase leads to a drop in this indicator by 51% relative to the tillering phase and by 59% relative to control plants. The use of Nigor++ increases the immune status of plants, reduces the concentration of antioxidant substances or reduces their activity due to the formation of stable complexes with magnesium ions included in BP, as well as binding them to highly active free radicals that occur during autoxidation, converting them to low-activity.

Open bite can be defined as an absence of occlusion, most frequently located in the anterior region of dental arches and its etiology is multifactorial. We present a clinical case of an 8 years and 10 months child presenting an anterior open bite (AOB) with transverse maxillary deficiency caused by tongue thrust during mixed dentition. The malocclusion was corrected by means of a McNamara expander with a palatal crib jointly with the association of speech therapy for tongue repositioning, and otolaryngology to treat adenoid hypertrophy due to its correlation with AOB. The multidisciplinary approach was effective in correcting the malocclusion with stable results after 2 years post-treatment.
İngiliz İdaresi Döneminde Kıbrıs’ta İki Kilise Krizi
Authors: Şengil Mustafa
Published: December 2021

Bu çalışma Osmanlı Devleti’nin Kıbrıs Adası’nı fethi ile özgürlüğünü yeniden kazanmış olan Kıbrıs Rum Ortodoks Kilisesi’nin, İngiliz idaresi döneminde yaşamış olduğu iki siyasi kilise krizini konu etmektedir. İngilizlerin Kıbrıs’ta idaresi iki döneme ayrılmaktadır. Birincisi 1878 yılında Osmanlı Devleti ile yapılan iki maddelik antlaşma kapsamında 1914 yılına kadar devam eden ve adanın fiilen Osmanlı toprağı olarak kabul edildiği dönem; ikincisi ise 1914 yılında İngiltere’nin adayı tek taraflı ilhakından 1960 yılında Kıbrıs Cumhuriyeti’nin kurulmasına kadar olan dönemdir. İngiliz idaresi döneminde gerçekleşmiş olan kilise krizlerinin ilki 1900-1910 yılları arasında Kitium Piskoposu Kyrillos Papadopoulos ile Girne Piskoposu Kyrillos Basileiou arasında gerçekleşmiştir. İkincisi ise 1933-1947 yılları arasında Baf Metropoliti Leontios Leontiou’nun 1931 isyanları sebebiyle ada dışında sürgünde olan metropolitlerin adaya dönmeden seçim yapılamayacağını beyan etmesi sebebiyle gerçekleşmiştir. Kıbrıs Rum Ortodoks Kilisesi otosefal bir kilise olması sebebiyle iç işlerine diğer kiliseleri karıştırmak istememiş, ancak çıkmaza giren piskoposluk seçimi nedeniyle müdahale kaçınılmaz olmuştur. Bugüne kadar siyasetteki etkisi var olagelen Kıbrıs Rum Ortodoks Kilisesi, 20. Yüzyılın henüz başında geçirmiş olduğu kilise krizlerini ancak siyasetin etkisi ve yardımıyla aşabilmiştir. Kıbrıs’ta ilk Yunan bayrağı birinci kilise krizi döneminde bir taraftar toplama çalışması olarak II. Kyrillos (Kyrillos Papadopoulos) tarafından Trooditissa Manastırı’na çekilmiştir. Ancak Kıbrıs Adası’nın ne daha önceki dönemlerde ne de şimdi Yunanistan ile hiçbir bağı yoktur. Kıbrıs Adası’nda yaşayan Rumlar ile Yunanistan arasında bir bağ oluşturmaya çalışan ve bunu iddia eden de yine kilisedir. Kıbrıs Cumhuriyeti birinci Cumhurbaşkanı III. Makarios’un başpiskopos seçilmesine giden süreçte bahsedilen iki kilise krizi büyük önem taşımaktadır. Bu dönemde başpiskopos adayları arasında, rakip adaya karşı Enosis’i ateşli bir şekilde savunmamak, İngiliz idaresine fazla yakın olmak gibi suçlamalar olmuştur. III. Makarios hem ateşli bir şekilde Enosis’i savunmuş, hem de İngiliz idaresi ile her zaman çatışma halinde olmuştur. Bu süreç ona önce başpiskoposluk, sonrasında ise Kıbrıs Cumhuriyeti Cumhurbaşkanlığı getirmiştir. Kıbrıs’ta zikri geçen dönemde özellikle ön plana çıkan Türk düşmanlığı, başpiskopos olmanın ilk şartı sayılmıştır. Şöyleki; İngilizler adayı tek taraflı ilhak ettikten sonra İngilizlerin adayı kendilerine bırakacağına neredeyse emin olan Rum Ortodoks Kilisesi başpiskoposları, önce İngiliz idaresi düşmanlığı, sonra Türk düşmanlığı üzerinden kilise propagandası yapmışlardır. Çalışmada otosefal bir kilise olan Kıbrıs Rum Ortodoks Kilisesi’nin, kilise içi anlaşmazlıklardaki tavrı ile kilise kurallarına bağlılığı da ele alınmaktadır. Enosis düşüncesinin piskoposluk seçimine etkisinin daha net görüleceği bu iki kriz, kilisenin bugününü anlamak açısından oldukça önemlidir.

Amidoxime derivatives have practically valuable biological properties. We have previously obtained new spiropyrazolinium compounds by arylsulfo-chlorination of β-aminopropioamidoximes, but in case of β-(benzimidazol-1-yl)pro-pioamidoxime we have obtained O-substitution product – 3-(1H-benzo[d]imidazol-1-yl)-N'-(tosyloxy)pro-panimidamide. The aim of the work is predicting of structural parameters (bond lengths, bond angles), vibrational frequencies and NMR spectra of 3-(1H-benzo-[d]imidazol-1-yl)-N'-(tosyloxy)propanimidamide. The calculations were performed using Gaussian 09 package. Structural parameters and vibrational frequencies was calculated using DFT (B3LYP/B3PW91/WB97XD)/6-31G(d,p). 1H and 13C NMR was predicted using DFT B3LYP/6-31G(d,p)-GIAO in DMSO. All calculated values are in good agreement with experimental data. The calculated bond lengths and bond angles were compared with results of X-ray structural analysis. The best correlation coefficient was 0.981 (calcu-lations with B3LYP level). For bond angles, the best result was obtained with B3LYP level (0.990). For vibrational frequencies correlation coefficients between the calculated and experimental values were 0.997 (B3LYP), 0.996 (B3PW91) and 0.995 (WB97XD). The most accurate method was used for predic-ting NMR spectrum. The correlation coefficients between the experimental and calculated 1H and 13C chemical shifts were 0.949 and 0.999 respectively.

The aim of this research work is comparative study of influence of ionic radii of heavy metal ions of neodymium and scandium on their sorption process from corresponding water solutions of sulfates by sorbents such as individual ion-exchangers Amberlite IR120, AB-17-8 and mixture of these sorbents related to interpolymer system Amberlite IR120-AB-17-8 at the various molar relations. Laboratory experiments of this work of sorption heavy ions of neodymium and scandium were carried out and inves-tigated by using the following physico-chemical methods of analysis: conductometry-based on the electrical conductor, pH-metry-based on the concentration of hydrogen ions, colorimetry, atomic-emission spectro-scopy. Ion-exchangers in the interpolymer system undergo remote interaction with further transition into highly ionized state. There is formation of optimal conformation in structure of the initial ion- exchangers. Significant increase of ionization of the ion-exchange resins occurs at molar ratio Amberlite IR120:AB-17-8 = 5:1. Significant increase of sorption properties is observed at this ratio due to mutual activation of ion-exchangers. The extraction rate of Nd3+ ions in 48 hours is 42.32%, and the extraction rate of Sc3+ ions is 38.06%. A possible reason for higher sorption of neodymium ions in comparison with scandium ions is maximum conformity of globes of internode links of Amberlite IR120 and AB-17-8 after activation to sizes of neodymium sulfate in an aqueous medium.

Petrochemical products based on petroleum naphthenic acids have special properties. Esters of naphthenic acids possess practically valuable organic compounds. The aim of this work is the development of effective methods for the preparation of aromatic esters based on naphthenic and individual fatty acids which is a very promising direction in the medicine practice. The synthesis of unsaturated racemic and chiral oxyethers was carried out on the basis of the interaction of chloromethylpropargyl (allyl) esters with carbonyl compounds with the participation of metallic zinc. Also, to study the biological activity, racemic and optically active esters were synthesized based on naphthenic acids and unsaturated racemic and chiral oxyesters. As test cultures used: gram-positive (Staphylo-coccus aureus-Staphylococcus aureus), gram-negative (Pseudomonas aeruginosa – Pseu-domonas aeruginosa, Escherichia coli) bacteria, as well as yeast-like fungi of the genus Candida - Candida albicans. Analysis of the biological activity of the synthesized compounds showed that optically active bicyclo [2.2.1] hept-5-ene-2-methylol monoesters have higher antimicrobial and antifungal activity compared to their racemic analogs and drugs used in medicine.
