The Impact of E-Visits on Visit Frequencies and Patient Health: Evidence from Primary Care
Authors: Bavafa Hessam , Hitt Lorin M. , Terwiesch Christian
Published: February 2018

Secure messaging, or “e-visits,” between patients and providers has sharply increased in recent years, and many hope they will help improve healthcare quality, while increasing provider capacity. Using a panel data set from a large healthcare system in the United States, we find that e-visits trigger about 6% more office visits, with mixed results on phone visits and patient health. These additional visits come at the sacrifice of new patients: physicians accept 15% fewer new patients each month following e-visit adoption. Our data set on nearly 100,000 patients spans from 2008 to 2013, which includes the rollout and diffusion of e-visits in the health system we study. Identification comes from difference-in-differences estimates leveraging variation in the timing of e-visit adoption by both patients and providers. We conduct several robustness checks, including matching analyses and an instrumental variable analysis to account for possible time-varying characteristics among patient e-visit adopters.

Published: February 2018

Abstract. Professional drivers have been found to be at a high risk of developing low back pain due to prolonged sitting and vehicle vibration. In a previous survey carried out on 1,155 tractor drivers, tractor vibration and/or incorrect posture while driving were found to cause low back disorders in more than 80% of the interviewed drivers. In this context, the present research introduces a new evaluation protocol to assess the ergonomic characteristics of agricultural tractor seats through the use of pressure sensors, taking into account both static and dynamic conditions. The degree of comfort was defined by analyzing the pressure distribution exerted by a sample of 12 drivers sitting on two seats in five different operating conditions. The pressure distribution values thus obtained were compared with the corresponding pressures recorded with the 12 drivers sitting on a reference seat (rigid seat, backrest, and suspension) designed for the purpose. From the comparison, it was possible to define a comfort index (CI) that allowed an objective assessment of the two seats. Statistical analysis showed that the CIs of the two seats were significantly different in all five operating conditions. Moreover, the two seats showed different CIs as a function of the operating condition. Although less comfortable, one seat showed almost constant CI values in all five operating conditions. Conversely, the other seat showed a progressively decreasing CI from the static condition to the uneven ground condition. Keywords: Comfort index, Occupational diseases, Pressure distribution, Safety.

Students’ associating their knowledge with daily life demonstrates great significance in terms of understanding the importance of topics they learn in school as well as knowing where and how they are used in their daily life. In this context, teachers who will reflect these relationships in learning environments must have sufficient knowledge and experience. In this research, it was aimed to investigate the effects of teaching applications with real life content on the levels of pre-service teachers' abilities to associate daily life with astronomy and electrical learning topics. The sample consisted of totally 30 fourth class students who were at the department of Science Teaching in the Faculty of Education. In the research, astronomy and electrical learning topics were chosen and activities based on real life problems in these were applied. The data gathered were based on the effects of these activities. The research was conducted following an experimental design and data were collected applying the pre-post test pattern. The data were collected through open-ended questionnaires related to the use of learning topics in daily life. As a result, it was found that the levels of associating the learning topics with daily life were nearly doubled in the field of electrical and astronomy learning topics.

Dynamic Flexibility in Striatal-Cortical Circuits Supports Reinforcement Learning
Authors: Gerraty Raphael T. , Davidow Juliet Y. , Foerde Karin , Galvan Adriana , Bassett Danielle S. , Shohamy Daphna
Published: February 2018

Complex learned behaviors must involve the integrated action of distributed brain circuits. Although the contributions of individual regions to learning have been extensively investigated, much less is known about how distributed brain networks orchestrate their activity over the course of learning. To address this gap, we used fMRI combined with tools from dynamic network neuroscience to obtain time-resolved descriptions of network coordination during reinforcement learning in humans. We found that learning to associate visual cues with reward involves dynamic changes in network coupling between the striatum and distributed brain regions, including visual, orbitofrontal, and ventromedial prefrontal cortex (n= 22; 13 females). Moreover, we found that this flexibility in striatal network coupling correlates with participants' learning rate and inverse temperature, two parameters derived from reinforcement learning models. Finally, we found that episodic learning, measured separately in the same participants at the same time, was related to dynamic connectivity in distinct brain networks. These results suggest that dynamic changes in striatal-centered networks provide a mechanism for information integration during reinforcement learning.

SIGNIFICANCE STATEMENTLearning from the outcomes of actions, referred to asreinforcement learning, is an essential part of life. The roles of individual brain regions in reinforcement learning have been well characterized in terms of updating values for actions or cues. Missing from this account, however, is an understanding of how different brain areas interact during learning to integrate sensory and value information. Here we characterize flexible striatal-cortical network dynamics that relate to reinforcement learning behavior.
Basolateral Amygdala Inputs to the Medial Entorhinal Cortex Selectively Modulate the Consolidation of Spatial and Contextual Learning

Published: February 2018

Although evidence suggests that the basolateral amygdala (BLA) and dorsal hippocampus (DH) work together to influence the consolidation of spatial/contextual learning, the circuit mechanism by which the BLA selectively modulates spatial/contextual memory consolidation is not clear. The medial entorhinal cortex (mEC) is a critical region in the hippocampus-based system for processing spatial information. As an efferent target of the BLA, the mEC is a candidate by which the BLA influences the consolidation of such learning. To address several questions regarding this issue, male Sprague Dawley rats received optogenetic manipulations of different BLA afferents immediately after training in different learning tasks. Optogenetic stimulation of the BLA–mEC pathway using ChR2(E123A) after spatial and cued-response Barnes maze training enhanced and impaired retention, respectively, whereas optical inhibition of the pathway using eNpHR3.0 produced trends in the opposite direction. Similar stimulation of the BLA-posterior dorsal striatum pathway had no effect. BLA–mEC stimulation also selectively enhanced retention for the contextual, but not foot shock, component of a modified contextual fear-conditioning procedure. In both sets of experiments, only stimulation using bursts of 8 Hz light pulses significantly enhanced retention, suggesting the importance of driving activity in this frequency range. An 8 Hz stimulation of the BLA–mEC pathway increased local field potential power in the same frequency range in the mEC and in the DH. Together, the present findings suggest that the BLA modulates the consolidation of spatial/contextual memory via projections to the mEC and that activity within the 8 Hz range is critical for this modulation.

SIGNIFICANCE STATEMENTThe mechanism by which the basolateral amygdala (BLA) influences the consolidation of spatial/contextual memory is unknown. Using an optogenetic approach with multiple behavioral procedures, we found that immediate posttraining 8 Hz stimulation of BLA projections to the medial entorhinal cortex (mEC) enhanced retention for spatial/contextual memory, impaired retention for cued-response memory, and had no effect on foot shock learning for contextual fear conditioning. Electrophysiological recordings confirmed that 8 Hz stimulation of this pathway increased activity in the 8 Hz range in the mEC and in the dorsal hippocampus, a region critical for spatial memory consolidation. This suggests that coordinated BLA activity with downstream regions in the 8 Hz activity range immediately after training is important for consolidation of multiple memory forms.
Effects of curvature-related DEM contact model on the macro- and micro-mechanical behaviours of granular soils
Authors: Zhao S. , Evans T. M. , Zhou X.
Published: February 2018

A comprehensive comparison between the Hertz–Mindlin model and the linear spring model in true triaxial shear simulations of granular soils was conducted using the discrete-element method (DEM). The no-slip Hertz–Mindlin model for general elastic non-spherical particles with smooth surfaces was revisited and implemented for superellipsoidal particles in an in-house DEM code. Three groups of specimens with a grain size distribution of Ottawa 20–30 sands, consisting of spheres, ellipsoids and superellipsoids, respectively, were subjected to triaxial shear DEM simulations with the Hertz–Mindlin model and the linear spring model. The corresponding mechanical behaviours were examined in terms of a series of macro- and micro-parameters. It was found that the linear spring model was able to resemble the Hertz–Mindlin model in aspects of both microscopic and macroscopic mechanical behaviours of granular media with spherical and/or non-spherical particles. This finding suggests that the linear spring model can be used to investigate micro-mechanical behaviours of granular soils, even with complex particle shapes.

Mass Population Displacement and Retail Activities in the Wake of Hurricane Katrina
Authors: Gagnon Etienne , Lopez-Salido J. David
Published: February 2018

This week marks the 10th anniversary of Hurricane Katrina's tragic landfall near New Orleans, Louisiana, and the forced relocation of hundreds of thousands of families who lost their homes in the disaster. This mass population displacement boosted, for an extended period, population density and store frequentation in areas that were relatively spared by the storm. This note argues that supermarkets that weathered the hurricane raised prices little despite facing markedly higher store traffic and likely disruptions to their supply chains.

Published: February 2018

Hilsa, Tenualosa ilisha is a highly prestigious fish for esteemed delicious taste, high market demand and price. It forms an important fishery of funnel-shaped 72 km long Narmada Estuary. Rapid decline in hilsa catch has been recorded in the Narmada Estuary over last few decades. Hilsa catch was recorded 5180 ton in 2006–07 that reduced to only 419 ton in 2014–15. Pre-impoundment of dam showed that T. ilisha contributed to the tune of 977.1 to 3727 ton from 1974–75 to 1982–83 and the highest catch of hilsa was 15319 ton during 1993–94. Sardar Sarovar Dam started functional in the year 1994 which has impacted natural water flow of the river and resulted in a reduction of freshwater availability in the estuary; the development of sand bars at the mouth of the estuary also reduced the tidal ingress into the system; low depth, loss of breeding, nursery and feeding grounds, over fishing may be the most important factors affecting hilsa fishery in Narmada estuary. Catching of juvenile hilsa during winter by ‘Golava’ net (small meshed bag net) also led to a rapid decline in hilsa catch. To maintain the sustainable yield of hilsa, selective fishing and control of juvenile catch are the prerequisites along with maintaining regular flow from the dam.

Методом теории функционала проведено численное моделирование электронной структуры закрытых ук-УНТ(0,9) симметрий D3h/D3d и D3 в спинсинглетном и спинтриплетном состоянии для различных величин внешнего электрического поля. Установлена монотонная убывающая зависимость спиновой поляризации при дискретном наращивании длины трубки.

Показано, что модуляция поляризации в электрическом поле имеет спинзависимый характер: для электронов со спином “вверх” при приложении поля поляризация снижается, для электронов со спином “вниз” поляризация возрастает. При критической величине электрического поля происходит инверсия спиновой поляризации, главным каналом проводимости становится канал со спином “вниз”.

Развитые методы синтеза, высокая стабильность и возможность управления спиновой поляризацией приложением внешнего электрического поля позволяют рассматривать ук-УНТ как перспективный материал для создания спиновых вентилей и других функциональных устройств спинтроники.

Published: February 2018

В работе приведены результаты исследования фазовых равновесий в четверной системе Tl-Pb-Sm-Te в концентрационной области Tl4PbTe3-Tl9SmTe6 методами дифференциального термического (ДТА) и рентгенофазового (РФА) анализов, а также измерений микротвердости.

Показано, что Т-х диаграмма характеризуется образованием непрерывного ряда твердых растворов (δ-фаза). В целом данный разрез является неквазибинарным вследствие инконгруэнтного характера плавления Tl9SmTe6. В широком интервале составов (>35 mol.% Tl4PbTe3) в нем происходит первичная кристаллизация TlSmTe2, что приводит к образованию на диаграмме состояния фазовых областей L+TlSmTe2 и L+TlSmTe2+δ.

Кривая зависимости микротвердости от состава имеет пологий максимум, что характерно для систем с неограниченными твердыми растворами замещения.

Данные порошковых рентгенограмм показали, что все сплавы по разрезу Tl4PbTe3-Tl9SmTe6 являются однофазными и имеют тетрагональную структуру типа Tl5Te3. Параметры кристаллической решетки твердых растворов подчиняются правилу Вегарда.

Полученные экспериментальные данные могут быть использованы для выбора составов раствор-расплав для выращивания монокристаллов δ-фазы, представляющих интерес для разработки термоэлектрических преобразователей энергии.

Данная работа направлена на изучение механизмов переноса амфолитов в каналах обессоливания электродиализаторов. Объектом исследования является гомогенная анионообменная мембрана АХ, которая находится в 0.02 М растворе NaH2PO4. В результате реакций протонирования-депротонирования аниона дигидрофосфата он может трансформироваться в анионы гидрофосфата и фосфата с образованием протонов и ионов гидроксила, которые могут принимать участие в переносе заряда в системе AX/NaH2PO4. Мы предлагаем достаточно простую методику, которая позволяет определить парциальные токи и числа переноса противоионов через анионообменную мембрану, а также оценить количество протонов, поступающих от границы этой мембраны в канал обессоливания электродиализатора в допредельных и сверхпредельных токовых режимах. С помощью этой методики показано, что трансформация в мембране однозарядных анионов H2PO4– сначала в двухзарядные HPO42–, а затем в трехзарядные PO43– ионы является причиной отличий формы суммарных вольтамперных характеристик по сравнению с получаемыми в растворах NaCl.

Medya gibi insan odaklı bir sektörde gerek insanın, gerekse ürettiklerinin kurumlara katacağı artıları düşündüğümüzde entelektüel sermayenin medya endüstrisi için önemi yadsınamaz. Türkiye’de iş gücü devir hızı yüksek olan medya kuruluşlarında, çalışanların bağlılığını özel ve kamu sektörü ekseninde analiz etmeye çalışan bu araştırma, bir doktora tezinden esin alınarak geliştirilmiştir. Psikolojik sözleşme kavramından hareket eden tezden farklı olarak, araştırmayı örgütsel bağlılık konusu bağlamında inceleyen bu çalışmaya, ayrıca özel-kamu karşılaştırması dahil edilmiştir. Araştırma kapsamında medyanın çeşitli alanlarında çalışan 8 kişi ile derinlemesine görüşmeler yapılmıştır. Kamu ve özel sektör karşılaştırmasında örneklemin dengeli olabilmesi amacıyla her iki sektörden 4’er katılımcıya ulaşılmıştır. N-Vivo 8 yardımıyla içerik çözümlemesi yaparak analiz edilen tüm bulgular, araştırma için yeni geliştirilen bir veri kodlama cetveliyle değerlendirilmektedir. Bu çalışmanın amacı medyada faaliyet gösteren kamu ve özel sektör çalışanlarının örgütsel bağlılıklarını sorgulamak, aynı zamanda bağlılığı etkilediği varsayılan faktörleri karşılaştırmalı olarak analiz etmektir. Araştırmada her iki sektör yapısı için artı ve eksiler vurgulandıktan sonra, bulgulanan sorunlara ilişkin öneriler de geliştirilmiştir. Sonuç olarak; özel medya kuruluşlarında tespit edilen sorunlar iş güvencesinin azlığı, yönetim baskıları ve maddi şartlardaki yetersizlikler olurken, kamuda siyasi etkileşimlerin kadro ve yönetime etkisi, idarecilerin çalışanlara göre oransal fazlalığı ve kadrolu-sözleşmeli çalışan ayrımı temel problemler arasında yer almıştır. Her iki sektörde de işe duyulan sevgiden kaynaklanan bağlılığın güçlü olduğu görülmektedir. Ayrıca medya sektöründe tespit edilen sorunlar nedeniyle örgütsel bağlılık türleri içinde en çok devam bağlılığına ilişkin temalarla karşılaşılmıştır.

Quais conhecimentossaberes se espera construir com o planejamento do turismo com as (e pelas) comunidades? Qual o papel do bacharel em turismo no planejamento do turismo de base comunitária? Acredita-se que a acepção do planejamento do turismo de base comunitária no Brasil necessita ser debatida à luz da teoria da participação social, do desenvolvimento comunitário, assim como do planejamento participativo. Essas perspectivas permitem maior clareza e leitura crítica dos processos de intervenção nos territórios ditos comunitários, o que suscita a reflexão dos limites e potencialidades da conotação da participação social. O que se pode pensar é que a política pública de turismo não legitima os sentidos genuínos da participação social. O debate teórico encaminha argumentos sobre os riscos da reprodução da lógica convencional em contextos comunitários e que incentive a autonomia nas chamadas comunidades.

The cultivated rubber clones are sensitive to latex harvesting regimes according to their laticiferous metabolism. Thus, in order to determine the best latex harvesting systems of clones with active or rapid metabolism (IRCA 18, IRCA 130, PB 235, PB 260 and PB 330), six latex harvesting technologies are applied to them in a bulk statistical device from Fisher to four rehearsals. The rubber is tapped in downward half spiral stimulated or not for nine years after the opening of the tapping panel. The agronomic parameters (production, vegetative growth), the tapping panel dryness and those of the latex micro diagnosis were evaluated. The results indicate that these clones independently of the latex harvesting system have good rubber productivity (2310 kg.ha -1.y1) with good radial vegetative growth (2.9 cm.y-1). Their trees show a wellbalanced physiological profile and an acceptable sensitivity to the tapping panel dryness (4.9%). However, the physiological index, the bark consumption and the sensitivity to the tapping panel dryness lead to retain the latex harvesting technologies “ S/2 d3 6d/7 Pa1(1) ET2.5% 4/y and S/2 d4 6d/7 Pa1(1) ET2.5% 4/y ” for the best. This index, favorably influencing the choice of technologies adapted to clones with active metabolism, contributes to the modern and efficient management of a rubber plantation.
Caféiculture Et Accès Aux Soins De Santé Au Burundi : Analyse De La Dynamique Des Mutuelles De Santé Des Caféiculteurs De La Province Kayanza Au Nord Du Burundi
Authors: Alexis Ndabarushimana
Published: February 2018

This article highlights the dynamics of health mutuals of coffee farmers in Kayanza province. It shows the factors related to difficulties in accessing health care for coffee growers in Kayanza province. These factors are fundamentally linked to the socio-economic environment that structures the living conditions of coffee growers in a world where the Burundian government has opted a ‘‘laissez-faire’’ and ‘‘laissez-aller’’ policy in the coffee sector. In order to do this, we opted for qualitative approaches with the use of the interview guide and quantitative with the use of a questionnaire administered directly to the coffee growers of Kayanza province. In this situation of self-determination of coffee growers, this article highlights the constraints faced by mutual health organizations in their mission to be able to access health care quality of coffee farmers after having shown the role played by mutuals and FEMUSCABU in promoting the solidarity of coffee farmers in Kayanza province. This article also highlights how mutualists behave with their social vulnerability.
Information Pour Le Développement Durable De La Santé – Cas De L’usage Des Réseaux Sociaux Dans La Lutte Contre Le Cancer De La Prostate En Côte d’Ivoire
Authors: Pascal Gnamien Kouamé
Published: February 2018

Prostate cancer is a pathology that causes casualties among the male population in Côte d'Ivoire. This pandemic kills silently but can be cured at the early stage of detection. All the actors in the fight against this pathology have mainly focused on the classical channels of communication and nonmedia. In the era of the information society, there is, however, a culture of digital technology in Côte d'Ivoire where the use of social networks is now part of the habits. While mass communication campaigns hinder efforts to raise awareness for early detection, more discreet and more customizable social networks have the advantage of reaching men who feel demeaned and humiliated when it comes to the «shameful, humiliating and dishonorable» disease of prostate cancer. The objectives of this research are to assess the impact of prostate cancer awareness campaigns on male population through traditional channels of communication and to analyze the determinants of the evolution of prostate cancer, despite all actions taken to propose solutions to curb the evolution of the disease. With the quantitative and qualitative approaches, the hypothesis that shows that there is a significant relationship between the evolution of prostate cancer among the male population and the late detection of this disease was confirmed. The communication strategies proposed by the various actors will then be effective, provided that social networks are associated with conventional media and non-media.

Aluniq: and her friend, Buster by A. Pingo
Authors: Campbell Sandy
Published: February 2018

Pingo, Anna.  Aluniq:  and her friend, Buster. Illus. Karleen Green. Inuvilauit Settlement Region, 2016.This is a simple story about separation of loved ones, a common, but none-the-less painful necessity in many remote communities. Aluniq is a little girl who lives with her Norwegian grandparents at the Qunngilaat Reindeer Station in Canada’s Northwest Territories. Aluniq has a pet reindeer calf named Buster. She has lived with her grandparents from birth because her mother has been away for years for tuberculosis treatment. Now that her mother is well and back in Tuktuuyaqtuuq, Aluniq must go to live with her parents, hundreds of kilometers away from the Station. But “Aluniq [is] frightened as she [doesn’t] know who these people [are].” Her grandparents are very sad to be separated from her and she is sad to be separated from them and from Buster. Although Aluniq does not recognize it at the time, this is also a story of reunion and of putting things right. Her parents are happy to have her return. This simple, but realistic story highlights the fact that many families in the Inuvialuit Settlement Region and other remote parts of Canada have been disrupted when people have had to leave home to receive medical treatment. It is clearly written and readable at an upper elementary level. Karleen Green’s drawings are rustic and unsophisticated, but are delightfully representative of the Inuit world and accessible to children. Available in English, as well as all three Inuvialuktun dialects, these books are appropriate for elementary school and public libraries and any collection of Canadian children’s literature.Highly recommended: 4 out of 4Reviewer: Sandy CampbellSandy is a Health Sciences Librarian at the University of Alberta, who has written hundreds of book reviews across many disciplines. Sandy thinks that sharing books with children is one of the greatest gifts anyone can give.
Young’s Equation vs. Sessile Drop Accelerometry: A Comparison Using the Interfacial Energies of Seven Polymer-water Systems
Authors: Calvimontes Alfredo
Published: February 2018

In this study, the values of the interfacial energies of seven different polymer-water systems obtained by Sessile Drop Accelerometry (SDACC) are compared with the values obtained by the Young’s-equation-based Owens-Wendt method. The SDACC laboratory instrument –a combination of a drop shape analyzer with high-speed camera and a microgravity tower- and the evaluation algorithms, are designed to measure the interfacial energies as a function of the geometrical changes of a sessile droplet shape due to the effect of “switching off” gravity during the experiment. The method bases on Thermodynamics of Interfaces and differs from the conventional aproach of the two hundred-years-old Young’s equation in that it assumes a thermodynamic equilibrium between interfaces, rather than a balance of forces on a point of the solid-liquid-gas contour line. A comparison of the mathematical model that supports the SDACC method with the widely accepted Young`s equation is discussed in detail in this study.

Published: February 2018

The technology of creating varieties of barley resistant to the smut diseases has been developed. Their cultivation will help to reduce crop losses, increase the profitability of seed production, improve the quality of seeds, and reduce the environmental risk from the use of chemical plant protection products. This technology was first implemented in the Kemerovo Region in 1988-1999. The wide distribution of species Ustilago nuda (Jens.) Kell. et Sw. (65 %) and U. nigra Tapke (35 %) was revealed. The covered smut ( Ustilago hordei (Pers.) Kell. Et Sw.) was registered in individual collection varieties. The first and tenth races of a loose smut and the sixth race of a black loose smut were identified. The sources of individual and group immunity to the smut fungi from the world gene pool of barley are distinguished: Moskovsky 3/125, Suzdalets, Ramos (Moscow Region); Kazer (Rostov Region); line 3 KM-1192 (Belarus); Kumir Odessky (Ukraine); Guardian (Canada). The donor properties of resistance to a loose smut in the Bagan variety, line 53 HVS 91/76, line 1899 were studied. They are recommended for use in breeding programs. With their participation a new hybrid fund was created. Variability and inheritance of quantitative traits of productivity of hybrids was studied. To select the recombinants immune to the loose smut in combination with high productivity, the most promising combinations of hybrids have been identified: Bagan × Viner; Bagan × KM-16; l. 53 HVS 91/76 × KM-7; KM-7 × l. 1899; l. 1899 × KM-7. Among them, prospective breeding lines have been selected. The results of the implementation of technology elements in the selection of barley for resistance to smut fungi is the creation of immune highly productive varieties of a new generation: Simon and Luka (Kemerovo Region). They are included in the State register of breeding achievements since 2004.
LIQUID- SOLID AND LIQUID-VAPOR PHASE EQUILIBRIUM IN SECONDARY ALCOHOL - n-ALKANE SYSTEM

Primary and secondary alcohols, obtained as a product of processing of plant raw materials, can be used as additives in fuel. Mixtures of n-alkanes, cyclic alkanes and aromatic hydrocarbons can act as a model for gasoline and diesel fuel. Therefore, it is necessary to study the characteristics of mixtures of alcohols with normal, cyclic and aromatic hydrocarbons. To simulate liquid-solid and liquid-vapor phase equilibria, a method is used to minimize excess Gibbs energy by the solvation parameter. The authors developed the PCEAS (Phase Charts Eutectic and Azeotropic Systems) software. The input data in the case of constant pressure are the temperature T 0 and the enthalpy of the phase change H 0 of the pure components. Prediction of the thermodynamic parameters of secondary alcohols is used to calculate the eutectic and azeotropic parameters of the secondary alcohol - n-alkane mixture: composition, temperature, melting enthalpy and evaporation. The model makes it possible to determine the average value of the association parameter in the liquid phase k . Experimental data for azeotropic mixtures made it possible to establish the association parameter in the vaporphase  of the systems under study. The results of calculations can be used to select the optimal composition and obtain the requiredcharacteristics of biofuel.
