Investigation of the Incompatibilities of Cement and Superplasticizers and Their Influence on the Rheological Behavior
Authors: Pott Ursula , Jakob Cordula , Jansen Daniel , Neubauer Jürgen , Stephan Dietmar
Published: February 2020

The rheological behavior of cement paste and the improvement of its flowability takes center stage in many research projects. An improved flowability can be achieved by the addition of superplasticizers (SP), such as polycarboxylate ethers (PCE). In order to be able to use these PCEs effectively and in a variety of ways and to make them resistant to changes in the environment, it is crucial to understand the influence of SPs on cement hydration. For that reason, the topic of this paper was the incompatibility of a specific SP and an ordinary Portland cement (OPC). The incompatible behavior was analyzed using rheological tests, such as the spread flow test and penetration test, and the behavior was compared by means of an ultrasound technique and explained by the phase content measured by in-situ X-ray diffraction (XRD) the heat evolution measured by calorimetry, and scanning electron microscope (SEM) images. We showed that the addition of the SP in a high dosage led to a prevention of the passivation of the most reactive and aluminum-containing clinker phases, aluminate and brownmillerite. This induced the aluminate reaction to take place in the initial period and led to an immediate stiffening of the cement paste and, therefore, to the complete loss of workability. The results showed that in addition to the ettringite, which began to form directly after water addition, hemicarbonate precipitated. The fast stiffening of the paste could be prevented by delayed addition of the SP or by additional gypsum. This fast stiffening was not desirable for SPs, but in other fields, for example, 3D printing, this undesirable interaction could be used to improve the properties of printable mortar.
Validation of Screen-Printed Electronic Skin Based on Piezoelectric Polymer Sensors
Authors: Fares Hoda , Abbass Yahya , Valle Maurizio , Seminara Lucia
Published: February 2020

This paper proposes a validation method of the fabrication technology of a screen-printed electronic skin based on polyvinylidene fluoride-trifluoroethylene P(VDF-TrFE) piezoelectric polymer sensors. This required researchers to insure, through non-direct sensor characterization, that printed sensors were working as expected. For that, we adapted an existing model to non-destructively extract sensor behavior in pure compression (i.e., the d33 piezocoefficient) by indentation tests over the skin surface. Different skin patches, designed to sensorize a glove and a prosthetic hand (11 skin patches, 104 sensors), have been tested. Reproducibility of the sensor response and its dependence upon sensor position on the fabrication substrate were examined, highlighting the drawbacks of employing large A3-sized substrates. The average value of d33 for all sensors was measured at incremental preloads (1–3 N). A systematic decrease has been checked for patches located at positions not affected by substrate shrinkage. In turn, sensor reproducibility and d33 adherence to literature values validated the e-skin fabrication technology. To extend the predictable behavior to all skin patches and thus increase the number of working sensors, the size of the fabrication substrate is to be decreased in future skin fabrication. The tests also demonstrated the efficiency of the proposed method to characterize embedded sensors which are no more accessible for direct validation.
Microwave Transmittance Technique Using Microstrip Patch Antennas, as a Non-Invasive Tool to Determine Soil Moisture in Rhizoboxes
Authors: Herrmann Paulo Sergio de Paula , Sydoruk Viktor , Marques Porto Felipe Nieves
Published: February 2020

Investigating the growth behavior of plant root systems as a function of soil water is considered an important information for the study of root physiology. A non-invasive tool based on electromagnetic wave transmittance in the microwave frequency range, operating close to 4.8 GHz, was developed using microstrip patch antennas to determine the volumetric moisture of soil in rhizoboxes. Antennas were placed on both sides of the rhizobox and, using a vector network analyzer, measured the S parameters. The dispersion parameter S21 (dB) was also used to show the effect of different soil types and temperature on the measurement. In addition, system sensitivity, reproducibility and repeatability were evaluated. The quantitative results of the soil moisture, measured in rhizoboxes, presented in this paper, demonstrate that the microwave technique using microstrip patch antennas is a reliable, non-invasive and accurate system, and has shown potentially promising applications for measurement of rhizobox-based root phenotyping.
Unambiguous Forward-Looking SAR Imaging on HSV-R Using Frequency Diverse Array
Authors: Zhang Mengdi , Liao Guisheng , He Xiongpeng , Zhu Shengqi
Published: February 2020

It is a challenge to realize wide swath imaging due to the conflict between Doppler ambiguity and range ambiguity for hypersonic vehicle (HSV) radar. In addition, there are many conditions requiring the forward-looking imaging. In a forward-looking synthetic aperture radar (SAR) system, left–right ambiguity arises, since two symmetrical targets have the same Doppler frequency magnitude. After selecting an appropriate pulse repetition frequency (PRF) to avoid Doppler ambiguity, we only need to solve the range ambiguity and left–right ambiguity. To handle these issues, this paper proposes an approach to resolve the range ambiguity and left–right ambiguity using the frequency diverse array (FDA). With the range-angle-dependent property of the transmit steering vector, FDA can distinguish the range ambiguous echoes in the spatial frequency domain. By performing transmit beamforming after range compensation, the echo from the desired range region can be extracted from ambiguous echoes. Then, the back projection (BP) algorithm is used to achieve imaging. Next, the echoes of all channels are processed by two receive beamformers, which are designed for the right and left sides, respectively. With the aforementioned procedures, an unambiguous image can be obtained. Simulation results have verified the effectiveness of the proposed approach.
Development and application of a Socioeconomic Vulnerability Indicator Framework (SVIF) for Local Climate Change Adaptation in Taiwan
Authors: Jhan Hao-Tang , Ballinger Rhoda , Jaleel Azmath , Ting Kuo-Huan
Published: February 2020

This paper outlines the development of a socioeconomic vulnerability indicator framework (SVIF) which was designed to provide a tool to inform bespoke local adaptation actions along the Taiwanese coast. The framework incorporates a range of diverse indicators, from ones that are related to demographic characteristics to others that represent economic and infrastructure features. As such, the framework encapsulates multiple and complex dimensions of socio-economic vulnerability rather than deriving a less nuanced single index; this is an approach that, whilst more commonly employed elsewhere, may mask critical features of socioeconomic vulnerability at local levels. The paper describes the piloting of the SVIF as it quantifies and visually summarizes the susceptibility and resilience of four townships (Mailiao, Kauho, Linbian and Jiadong) along the exposed coast of Southwest Taiwan. The paper demonstrates the SVIF’s potential in characterizing specific aspects of socio-economic vulnerability that local decision-makers could use to tailor local adaptation. The SVIF was successful in differentiating between the four local areas, highlighting clear differences between urban and rural townships. With further development by using a more participative approach and expanding its application to wider geographical contexts both in Taiwan and further afield, the authors are confident that the SVIF has the potential to provide a useful tool for local adaptation.

Multi Independent Steering System-based Robot to Help Persons with Disability
Authors: Fitrizia Anita
Published: February 2020

Abstract - Open research in the field of robotics encourages individual creativity to create creative solutions to help people with disabilities. Robots are technologies that can relieve or replace human power. The need to provide food for persons with disabilities is very important because of its limitations. Nurses are the general solution to the limitations of people with disabilities, but what happens in America is a frequent weather problem and brings nurses to help people with disabilities. So you need a tool that can replace the work of a nurse. The solution to this problem is to make robots that can replace several servants' tasks, such as taking, moving and putting food and beverage boxes from one place to another. Robotic maneuverability is an important part of the job. A multi-independent steering system is used to reduce the robot's movement space when maneuvering. Besides being able to maneuver, robots must be able to pick up and transport food and beverage boxes using a gripping system. The success rate of robots completing their assignments reached 93.75% of 112 tests. Keyword : robot, prototype, multi-independent steering, person with dissability

PID Control For Ping-Pong Balance With Ultrasonic Sensor And Servo Motor Based On Labview
Authors: Utama Ivan Candra
Published: February 2020

Abstract - The balancing ball system is a system where there is a ball that can move freely on a rod and the position of the ball move can be adjusted automatically according to the desired set point. The balancing ball system is a very important system in studying the control system. This is because the balancing ball system is an unstable system where the output of the system (ball position) always increases indefinitely for each input (rod angle) with a fixed value. Therefore, ball balancing systems require complex control theories. To be able to stabilize the balancing ball system, a controller is needed. In order to get the best controller, tuning the Integral Derifative (PID) controller parameter is done. In this tuning we can know the value of proportional gain (Kp), integral time (Ti) and derivative time (Td). The PID controller will give action to the balancing ball control based on the error obtained, the distance between the ultrasonic sensor and the desired ball is called the set point. LabVIEW software is used as a monitor, servo motor speed control. Keyword : Labview, Balance Ball, Arduino, Motor Servo, Ultrasonic Sensor
Las investigaciones en el Fuerte Blanca Grande
Authors: Merlo Julio Fabián , Merlo Luisina
Published: February 2020

En este trabajo se presenta una síntesis de la documentación generada a lo largo de los años en la zona de la Laguna Blanca Grande, que van desde los trabajos realizados por Bórmida, en los que describe y define al Blancagrandense como una industria lítica que surge en el 3500 a.C. y perdura hasta momentos históricos, sin hacer ninguna mención del Fuerte Blanca Grande. El fuerte es luego resaltado por los historiadores locales Arena, Valverde y Cortez, y retomado en los trabajos de Goñi y Madrid y del historiador local Paladino. Estos trabajos han sido continuados por nuestro análisis documental y arqueológico, este último efectuado en el sector noroeste y la parte posterior del fuerte, y la laguna. Desde mediados del siglo XX se generaron investigaciones de diferentes campos disciplinarios que nunca se cruzaron entre sí, ocultando o negando la continuidad del registro arqueológico, que refleja tanto las ocupaciones pre como postconquista de la región pampeana. En este trabajo se plantea que separar la arqueología en pre y postconquista restringe el conocimiento de nuestro pasado, estableciendo una división artificial en la arqueología pampeana.
“Atroces armas de fuego de antaño”, Remingtons letales:
Authors: Leoni Juan
Published: February 2020

Este trabajo aborda la cuestión de las armas de fuego empleadas por el ejército argentino en la guerra de frontera entre 1869 y 1877. Se combina la información documental y los conjuntos arqueológicos de dos instalaciones militares contemporáneas –Fuerte General Paz y Fortín Algarrobos– para caracterizar el armamento en servicio durante ese lapso. Este fue un período crucial, durante el cual comenzó un proceso de modernización y estandarización del armamento del ejército, centrado en torno a la incorporación de fusiles y carabinas monotiro de retrocarga de la familia Remington Rolling Block. Sin embargo, el registro arqueológico muestra que este proceso fue lento y que una sorprendente variedad de armas de fuego más antiguas (fusiles y carabinas de avancarga de sistema de disparo de percusión y posiblemente también de chispa) permanecieron en servicio, causando problemas logísticos y operativos. El trabajo discute también el impacto de la incorporación de los Remington en la guerra de frontera, criticando nociones deterministas muy difundidas y situando su efecto en un contexto político y económico más amplio.

Desafíos para una ampliación de las prácticas cívicas.
Authors: De Battista Giuliana
Published: February 2020

El objetivo de este escrito es reflexionar sobre el papel que han de jugar en el mundo actual los derechos humanos, a partir de una antinomia que está presente en la propuesta que hace H. Arendt en relación a este tópico. En términos de E. Balibar, dicha antinomia consiste en la conjugación de una crítica radical al fundamento antropológico (en virtud de la cual la naturaleza humana no preexiste a la concesión de derechos por parte de las instituciones), con una defensa inflexible de los derechos humanos que se ha de situar en el centro de la construcción democrática (¿qué resta por hacer cuando admitimos que son las mismas instituciones que hacen humanos a los sujetos a través de la concesión recíproca de derechos, las que puedan destruirlos o impedir su ejercicio?). A través de este desarrollo, se intentará dar cuenta de que, a la ambigüedad del planteo arendtiano, subyace una determinada concepción de la política que nos sugiere determinas vías de acción al mismo tiempo en que nos impone nuevos desafíos.

Com relação às fontes, foram utilizados, principalmente, os documentos relacionados ao currículo prescrito. A tipologia documental se enquadra nas fontes escritas impressas e manuscritas. Com relação à análise dos dados, se deu através da análise de discurso inspirada na perspectiva arqueológica de Foucault. Os significados sobre a recreação estavam demarcados pelos enunciados interesse e prazer. A recreação se entrecruzaria com os discursos biológico, psicológico e sociológico numa tentativa de superar uma perspectiva biológica presente na formação à época. Além disso, a recreação foi enunciada como ocupação das horas de lazer e foi considerada uma atividade e/ou uma possibilidade de uso das horas de lazer.
Apropriação de Equipamentos Públicos de Lazer por Usuários de Bicicleta
Authors: Sartori Ludmila Miranda , Silva Luciano Pereira da
Published: February 2020

Este estudo teve como objetivo investigar a apropriação do Parque Ecológico da Pampulha (PEP) por usuários de bicicletas. Quarenta e nove ciclistas responderam um formulário contendo perguntas que tratavam do perfil, apropriação e opinião a respeito do uso da bicicleta no PEP, na orla da Lagoa da Pampulha e em Belo Horizonte. As questões fechadas foram tratadas por uma análise quantitativa descritiva, enquanto as abertas foram examinadas pela análise de conteúdo. De um modo geral, as respostas apontam para uma percepção positiva dos visitantes em relação à liberação da entrada de bicicletas nos parques e à estrutura do PEP e da orla da Pampulha para se pedalar. Percebe-se que a liberação - além de estar de acordo com a expressividade do ciclismo na região - é uma forma de se democratizar a entrada do parque para aqueles que se apropriam do espaço público através desse instrumento. No entanto, os entrevistados anseiam por mais estruturas na cidade que permitam o uso da bicicleta, indicando o papel do PEP e da orla em permitir seu uso com segurança, uma vez que a insegurança aparece como a principal barreira para o uso da bicicleta em Belo Horizonte.
Abordagem Sociocognitiva do Discurso
Authors: Maciel Marcos Gonçalves , Saraiva Luiz Alex Silva , Martins José Clerton Oliveira
Published: February 2020

Pesquisas com enfoque qualitativo apresentam diferentes técnicas para a interpretação dos dados. Uma das alternativas é a abordagem sociocognitiva do discurso proposta pelo linguista Van Dijk. A ênfase é a interação de três dimensões categóricas: ideologia, contexto social e a cognição. Assim, o objetivo deste estudo é apresentar essa proposta como possibilidade para a interpretação nos Estudos do Lazer. Como base empírica analisamos o entendimento que profissionais de Educação Física e alunos de um programa governamental de atividade física em Belo Horizonte/MG têm sobre o lazer. Os resultados demonstram um paradoxo teórico-prático entre o entendimento e a vivência do lazer, notadamente quanto à atividade física realizada no referido programa. Concluímos que o uso dessa abordagem apresenta uma importante contribuição para a análise crítica do fenômeno social do lazer.

On the Computation of Integrals of Bivariate Gaussian Distribution
Authors: Savaux Vincent , Le Magoarou Luc
Published: February 2020

This paper deals with the computation of integrals
of centred bivariate Gaussian densities over any domain defined as an angular sector of R^2. Based on an accessible geometrical approach of the problem, we suggest to transform the double integral into a single one, leading to a tractable closed-form expression only involving trigonometric functions. This solution can also be seen as the angular cumulative distribution of bivariate centered Gaussian variables (X,Y). We aim to provide a didactic approach of our results, and we validate them by comparing with those of the literature.

Conclusão: Concluiu-se que a presença do alelo Arg do polimorfismo do TP53 Arg72Pro está associada ao aumento do risco de ocorrência do AVEH/aneurisma intracerebral.
Lettere a Giuseppe Dessí e a Luisa
Authors: Manzini Gianna
Published: February 2020

The friendship between Gianna Manzini and Giuseppe Dessí, reconstructed in this book thanks to the Alberto Baldi’s research, was born in the mid-1940s, in the context of her collaborations with the magazine "Prosa", and would last until 1974, year of the writer's death. After the two were forced apart, their meetings in Rome, once very frequent, would be replaced by a dense epistolary dialogue, which would later involve their respective partners as well. In her letters, with a tone becoming more and more confidential, Manzini talks to Dessí about illness and death, sometimes alludes to complex family relationships, complains about the difficulty of reconciling literary work with private life, all the while trusting in her friend’s understanding, closeness and discretion, and hoping he would help her decrypt Enrico Falqui’s often difficult personality. The appendix of the letters is properly noted, and contains a singular unpublished piece titled I sogni di Dessí, which Manzini had written for the Almanacco dei sogni, a radio broadcast of the 1960s. The conclusion of this volume is a precious anthology of dispersed criticism, containing reviews and essays about the writer’s works which were collected from newspapers and magazines.

FORMATION, FUNCTIONING AND DEVELOPMENT FEATURES OF AGRICULTURAL MARKETS IN UKRAINE
Authors: LOHOSHA Roman , KOLESNIK Tatyana
Published: February 2020

The article reviews the essence and content of scientific views on the category "agricultural market" and "infrastructure of agricultural market". It is established that the formation and fulfilling of an organized and transparent agrarian market with powerful and effective components that can reconcile the interests of agricultural producers and consumers, should be a network of market institutions such as exchanges, trading houses and other elements of infrastructure. It is proved that the modern market transformations of the agrarian sector of Ukraine, which are accompanied by constant modification of market relations, require new methods of organization of the agrarian market as a complex economic system in which many elements inherent in a market economy interact.
It is determined that the agrarian market performs a number of important functions (stimulating, informative, pricing, controlling, rehabilitation, reproductive, integrative, intermediary, regulatory), on which the effectiveness of its functioning and development depends. With a systems approach, it has been established that the agrarian market should be viewed as a complex system of interconnected and omplementary systems of lower order (consumer solvent demand, supply, agriculture, and market infrastructure and government regulation). It is established that the agricultural market has a number of distinctive features that differentiate it from other types / types of markets. At the same time, the agrarian market as a set of economic relations, which are formed in the sphere of exchange concerning the sale of agricultural products, operates on the basis of common economic laws (cost, saving of resources, equilibrium). It is proved that the efficiency of the agrarian market should be understood as a logically ordered system of subjects of high-quality infrastructure, principles and methods of its functioning in accordance with modern conditions. It ensures the balance of supply and demand, equilibrium price parity and the proper level of competitiveness of agricultural products to meet international requirements and the internal needs of society.
In the study we have found that the modern infrastructure of the agricultural market in Ukraine is on the stage of formation in accordance with the development of agrarian relations in the country, and its peculiarity is that it has many intermediary structures that do not provide a reasonable price for producers, while having this intermediary operations have a significant economic benefit, and domestic agricultural producers lose a significant portion of their economic profits. In addition, the agricultural market of Ukraine is characterized by a long process of creating a system of organizations, institutions, enterprises and establishing methods of their activity, which are aimed at carrying out operations on the sale and purchase of agricultural products.

LEGAL NATURE OF THE ENVIRONMENTAL IMPACT ASSESSMENT
Authors: OVERKOVSKA Tetiana
Published: February 2020

The main components of the legal nature of environmental impact assessment are considered as management functions in the field of environmental protection, rational use of natural resources and ensuring environmental safety due to the fact that the reasons for the current unsatisfactory state in the industry of natural resource use, environmental protection are ambiguous. It was determined that the legal regulation of environmental impact assessment should be considered an important step towards the harmonization of Ukrainian legislation with EU legislation in the field of environmental impact assessment. The procedural and rocedural aspects of environmental impact assessment are determined and reviewed, which are determined by a number of legislative and subordinate legal acts. It has been established that environmental impact assessment should be carried out in compliance with certain principles based on the provisions of current legislation on nature protection. The principle of the effectiveness of environmental impact assessment is analyzed through the prism of prohibiting or terminating the activity of an enterprise in case of violation of the legislation on environmental impact assessment. Attention is drawn to the legal requirements of the principle of reliability of information in relation to environmental impact assessment.

The compulsory provision of the principle of publicity in the process of impact on the environment, aimed at timely, adequate and effective informing of citizens, has been established. It is proved that the publicity and reliability of environmental information on environmental impact assessment act as two interrelated legal categories. It has been determined that the legal nature of the environmental impact assessment is based on the provisions of the current legislation of Ukraine and is aimed at observing law and order in the field of environmental protection.

Authors: KYSH Liydmila
Published: February 2020

In the article we analyze the state of development of the domestic agrarian sector of the economy and the tendency of the formation of export batches of products. The current pace of development of the agrarian sector shows that the production of agricultural products is growing faster than the growth of domestic demand, which necessitates the search for new trading partners. This provides an opportunity for expanding foreign markets, receiving currency revenues into the country's economy. We analyzed the commodity structure of the export and import of agricultural and food products. The top 10 agro-food export and import products for 2018 are identified. We have investigated the specifics of trade in agrarian products with the countries of the European Union. We found that the main products of Ukrainian agroexport, which were put on the EU market are cereals and oilseeds. Growth of exports to the EU countries also occurred due to an increase in the supply of niche, processed and prepared food products. As a result of our research, we analyzed the current state of agricultural markets and found that global trends in food consumption (population growth) and non-food use of oilseeds (feed and biodiesel), causes the problem of internal satisfaction of individual needs in many countries of the world, causes significant investments in this branch in Ukraine.

Authors: Hlushko Mariia
Published: February 2020

This paper analyzes art magazines and other periodicals in the context of the presentation of works by the famous sculptor Emmanuil Mysko, who holds a special place in the fine arts of Ukraine. The research material provides a brief overview of publications in art magazines and other periodicals that thoroughly acquaint the reader with the formation and evolution of Emmanuil Mysko's creative path. The focus is made on a holistic analysis of articles by art historians describing the artist's work, as well as publications containing only specific references to him. A number of well-known national art magazines, newspapers, newsletters, etc. covering the cultural and artistic events were selected for the study, namely, the magazine of the National Union of Artists of Ukraine "Fine Arts", "Art" magazine, "Free Ukraine" newspaper, Bulletin of the Lviv National Academy of Arts , "People's Notebooks", "Art Horizons" and others. The study outlines a number of trends regarding the presentation of material about Emmanuil Mysko, through which it can be argued that each of the authors tried to highlight as much as possible the key aspects of Emmanuil Mysko's activity in the field of monumental and decorative sculpture and to emphasize his contribution to the development of Ukrainian art. It is revealed that the talent, pedagogical and social activity, human qualities of Emmanuil Mysko and its impact on culture and art, have not been neglected by national scientists, art historians, researchers who in their works published on pages of art magazines and other periodicals describe various aspects of the life and work of a prominent Ukrainian sculptor, art critic, teacher, public figure Emmanuil Mysko. The need to create a structured bibliographic index has been identified, which will contain a complete list of articles on E. Mysko published since 1996, since the Bibliographic Index was published by that year. Also the main provisions and conclusions of the article can be used in the formation of the relevant sections of the new Bibliographic Index, which will become a basis for young researchers who will study the work of E. Mysko.
The Effect of Isothermal Annealing on the Structural and Magnetic Properties of the Bulk Amorphous Alloy: FeCoTiYB
Authors: Bloch Kasia , Nabialek Marcin , Szota Michal
Published: February 2020

The aim of this paper was to conduct studies concerning the magnetization of bulk amorphous Fe61Co10Ti4Y5B20 alloy when subjected to strong magnetic felds in the area known as the approach to ferromagnetic saturation. The samples were produced using the suction-casting method. The amorphicity of the investigated alloy, in the as-quenched state and after annealing process in a temperature below the crystallization temperature was verified using X-ray diffractometry. The magnetization was measured using a vibrating sample magnetometer. On the basis of the obtained results, the type of structural defects having influence on magnetization in high magnetic fields were determined. Analysis of the high-field magnetization curves has facilitated the calculation of the spin wave stiffness parameter. From this parameter, the range and strength of the exchange interactions could be determined.

Iron chlorosis represents a physiological phenomenon with negative impact on the quality and quantity of grape production in the vineyards. The bicarbonates are considered to be the main group of compounds which immobilize the iron in the soil in forms not assimilable by the plants. The grape production in conditions of iron deficiency can be improved significantly by applying foliar fertilizers. The best result in mitigating the effects of iron deficiency were obtained by the application of the fertilizers which, in addition to a complex mineral composition, also have a content of organic matter in the form of humic substances or protein hydrolysate.

Published: February 2020

The kinetic adsorption of p-cresol from aqueous solution onto mesoporous activated carbon was investigated for 100, 500 and 1000 mg L-1 initial concentrations, at constant 295 K temperature. The kinetic of the adsorption process was discussed using three kinetic models, i.e., pseudo-first order kinetic model, pseudo-second order kinetic model, and Avrami fractionary order kinetic model. In order to provide a mathematically rigorous method for evaluating the kinetic parameters using the original form of the kinetic models, the nonlinear regression was selected as most viable algorithm. The common statistical tools was employed to check the accuracy of fit measure, namely, sum of the squares of the errors SSE, reduced sum of the squares of the errors Red-SSE, coefficient of determination R2, adjusted coefficient of determination Adj R2 and standard deviation SD.

Published: February 2020

New and practical synthesis of (Z)-8-dodecene-1-yl acetate and (E)-8-dodecene-1-yl acetate were developed. The synthesis were based on a C3+C6=C9 and C9+C3=C12 coupling scheme, the starting material being 2-propyn-1-ol and 1,6-hexandiol. The routes involve, as the key step, the use of the same mercury derivative of the terminal-alkyne w-functionalised as intermediate. The first coupling reaction took place between methoxyallene and Grignard reagent of 1-tert-butoxy-6-bromo-hexan obtaining 1-tert-butoxy-non-8-yne, which is transformed in di[1-tert-butoxy-non-8-yne]mercury, the common intermediate in the synthesis of the two pheromones. In order to obtain (Z)-8-dodecene-1-yl acetate and (E)-8-dodecene-1-yl acetate, the mercury derivative was directly lithiated and then alkylated with 1-bromo-propan obtaining 1-tert-butoxy-dodec-8-yne. After acetylation of 1-tert-butoxy-dodec-8-yne and stereoselective reduction in the presence of NiP-2 catalyst gave (Z)-8-dodecene-1-yl acetate with 85 % isomeric purity. After reduction with lithium aluminium hydride of 1-tert-butoxy-dodec-8-yne and acetylation was obtained (E)-8-dodecene-1-yl acetate with 90% isomeric purity.
