Authors: Ekinci Zafer , Kurdal Esref , Coruh Meltem Kizilca 
Published: October 2019

Background:Turkey is approximately 72% of the world’s boron sources. Colemanite, tincal, ulexite and pandermite are among the most significant in Turkey. Boron compounds and minerals are widely used in many industrial fields.Objective:The main purpose of this study was to investigate the control of impurities in the boric acid production process using colemanite by carrying out the reaction with a mixture of CO2 and SO2 - water, and determining the appropriate process conditions to develop a new process as an alternative to the use of sulfuric acid. Due to worrying environmental problems, intensive studies are being carried out globally to reduce the amount of CO2 and SO2 gases released to the atmosphere.Methods:The Taguchi method is an experimental design method that minimizes the product and process variability by selecting the most appropriate combination of the levels of controllable factors compared to uncontrollable factors.Results:It was evaluated the effects of parameters such as reaction temperature, solid-to liquid ratio, SO2/CO2 gas flow rate, particle size, stirring speed and reaction time. The optimum conditions determined to be reaction temperature of 45°C; a solid–liquid ratio of 0.083 g.mL−1; an SO2/CO2 ratio of 2/2 mL.s−1; a particle size of -0.354+0 .210 mm; a mixing speed of 750 rpm and a reaction time of 20 min.Conclusion:Under optimum operating conditions, 96.8% of colemanite was dissolved. It is thought that the industrial application of this study will have positive effects on the greenhouse effect by contributing to the reduction of CO2 and SO2 emissions that cause global warming.

Published: October 2019

Background
Advances in experimental psychology have led to a better understanding of unconscious, automatic processes that result in individuals relapsing into their substance-using habits. While some reviews have demonstrated the effectiveness of bias retraining of these unconscious biases, there have been other reviews that have highlighted that bias retraining is not always effective. Other studies have revealed there was no baseline biases among some participants. An examination of mobile bias retraining interventions has also revealed mixed results, with some reporting effectiveness and others null findings. A recent feasibility and acceptability study, done by the authors, revealed that 53% of participants have had no baseline biases and 21% of those with positive baseline biases did not have a positive change in magnitude following intervention.

Objective
The aim of this paper was to explore potential variables (demographic and clinical) that could account for the negative baseline biases in the prior feasibility and acceptability study, and to discuss some of the factors that could account for the absence of baseline biases. We also explored potential reasons for why there was no reduction in the magnitude of attentional biases among individuals with baseline biases.

Methods
Participants who were in the rehabilitation phase of their treatment were invited to participate. During the study they had to complete a set of baseline questionnaires, and on each day that they were on the ward they had to complete an attention bias assessment and modification task and rate their cravings using a visual analogue scale. Attention bias was deemed to be present if individuals had a positive score.

Results
In our study, 53% (16/30) of individuals did not present with baseline attentional biases, and among those with positive baseline biases a total of 21% (3/14) of participants did not have a reduction in the overall magnitude of attentional biases. Chi-square analyses undertaken to compare the demographic characteristics of participants with and without baseline biases did not reveal any significant findings. However, with respect to clinical characteristics, those who had positive baseline biases had experimented with more substances.

Conclusions
Our study is one of the first to have explored negative findings in attention bias modification interventions for individuals with addictive disorders. We postulate that several factors could account for the absence of baseline biases and there being no changes following bias retraining. Future research ought to take into consideration these factors.
EXERCITOR AND MAGISTER NAVIS IN ROMAN LAW
Authors: Ignjatović Marija 
Published: October 2019

The legal position of the owner of a vessel (exercitor navis) and the captain of a vessel (magister navis), was not always precisely defined in Roman law. A number of factors had an influence on it, and the most important one was the development of the maritime trade itself, which had a direct impact on this issue. At the beginning of its development, taking into account its insufficiently developed navigation, it is clear that there was no need for defining the legal position of the owner of a vessel and the captain of a vessel and establishing the difference between them. Since the navigation was primitive in the first phases of the development of maritime sailing, it was necessary for the owner of a vessel to monitor his vessel during a journey and look after all the goods he was entrusted with and passengers who were transported. With the development of maritime trade, especially in the classical period, they started to perceive the owner and the captain of a vessel as two separate roles, which necessarily required clearly and precisely defining their legal position, i.e. the clear distinction of the rights and obligations of a person who was the owner of a vessel and a person who was entrusted with operating the vessel. In the postclassical period, with the general decadence which was omnipresent in the Roman society, the decadence in the navigation itself occurred, which caused a number of negative reflections, one of which was merging the roles of the owner and the captain of a vesselin one person again. In order to better understand the positive effects of the situation when the owner of a ship was also the captain of that ship in the period of the late republic, as well as the negative effects of the same merging of the roles which occurred in the Dominate period, this study is going to deal with the question of the legal position of exercitor and magister navis during three periods of the development of Roman law: the last centuries of the late republic, the classical period and the postclassical period.

Rice bran oil (RBO) derived from rice bran (RB) which could use as an alternative raw material for biodiesel production. Rice bran (dedak) are used as feed for poultry, pigs, and some dairy cattle because they are relatively cheap and do not require processing. The utilization of these oil further cheapen the cost of biodiesel and increased the economonic value of RB. The choice of RBO as a raw material for biodiesel due to the rice bran oil’s potentials. RBO is considered to be one of the most nutritious oils due to its favorable fatty acids composition and a unique combination of naturally occurring biologically active and antioxidant compounds (oryzanol, tocopherol, tocotrienol, phytosterol, polyphenol, dan squalene). The research emphazised on esterification reaction because of the rapid increase of FFA content in RBO after the milling of rice. Storage time of RB increased the FFA content. Mixing velocity dan time reaction was the other two variables which are affecting the esterification reaction. Those two variables are studied in this experiment.
Experiment were designed to examine the mixing velocity and temperature reaction to the conversion of fatty acid methyl ester (FAME). Reaction condition 20:1 molar ratio methanol to FFA content and 5%-v/v catalyst (to the oil) was used in all experiments. Mixing velocity and time reaction was arranged as follows: 500, 750, 1000 rpm and 40, 50, 60oC, respectively. Research conducted in four parts: soxhlet extraction with n-hexane as a solvent; oil-solvent separation process; and the last step was esterification reaction. Reaction conducted on three neck round bottom flask equipped with magnetic stirrer, refluk condenser and thermometer. Crude product was separated first from unreacted methanol, glycerol, and catalyst prior to physical analyzed of biodiesel’s properties. Conversion of FAME was calculated from acid value difference, after and before reaction conducted.
It was found that mixing velocity influenced the FAME conversion not significantly (specially in crude rice bran oil high fatty acid content esterification); increasing in temperature will increase the FAME conversion; kinetic reaction controlled by chemical reaction; and biodiesel product from this research already fullfill the requirements of Indonesian Standard of Biodiesel (FBI-SO1-03).
Aportes a la conservación poscosecha de flores de corte para productores del Gran La Plata

Published: October 2019

El Partido de La Plata y localidades vecinas constituyen la región de mayor producción de flores de corte de Argentina, la cual abastece de una amplia diversidad de especies florales a distintos puntos del país. La producción la realizan principalmente productores de tipo familiar, generando ingresos y mano de obra para la región. Uno de los problemas de mayor relevancia para los productores florícolas es la pérdida de calidad comercial de las varas florales después de la cosecha. La utilización de cámaras frigoríficas permite mantener la calidad comercial de las flores mejorando así su capacidad de negociación manteniendo el producto en contextos de bajo precio. Sin embargo, sólo un bajo porcentaje de productores cuentan con esta tecnología, dado que es costosa para su adquisición y funcionamiento operativo. Poder avanzar en tecnologías de conservación que reduzcan las pérdidas poscosecha y generen un mayor ingreso a los productores es uno de los desafíos para un sector que adolece en este tipo de tecnologías. Este trabajo describe un proyecto generado desde la Facultad de Ciencias Agrarias y Forestales con financiamiento del Programa “Agregando Valor” de la Secretaría de Políticas Universitarias de la Nación, en el cual se ensayaron tecnologías sencillas de bajo costo para la conservación poscosecha de flores de corte. El mismo surge de la demanda de los productores a través de un grupo de Cambio Rural (INTA-MINAGRO) y del mercado cooperativo de Flores (MERCOFLOR). Se buscó mejorar la conservación poscosecha de Alstroemeria x hybrida y Lilium longiflorum, especies cuyo cultivo se ha incrementado en los últimos años en la región y que presentan como problema poscosecha más visible el amarilleamiento de las hojas de la vara. Para ello, se utilizaron distintas fuentes de iluminación LED: blanco cálido o rojo+azul, siendo los controles almacenados en oscuridad. La intensidad de las fuentes se fijó en 50 µmol m-2 s-1, con un periodo de luz de 16 h. La temperatura de almacenamiento fue de 21ºC y la humedad relativa (HR) de 70%. El tratamiento con ambos tipos de luz LED logró un aumento de la vida útil de las varas en 7 días. Por otra parte, para evaluar el efecto hormonal en el retraso del amarilleamiento, se realizó un pulsado por 24 h en ácido gibérelico (AG3) 50ppm en varas de Alstroemeria y Lilium, pasando luego a agua destilada pH=3,5 a 21ºC y 70% HR. Se observó una mejor conservación de las varas en los tratamientos con AG3 con respecto al testigo en ambas especies a los días 7 y 14. Se concluye que las técnicas desarrolladas en este proyecto, de fácil apropiación por los productores familiares de la región, podrían generar un impacto positivo en el retraso del amarilleamiento y mejora de la calidad poscosecha de las flores de corte. Los resultados obtenidos fueron presentados en una jornada demostrativa en MERCOFLOR ante productores y floristas. Se realizaron cartillas informativas con las tecnologías ensayadas y recomendaciones prácticas para su implementación.
Investigation of the Variability of EPSTAL Steel Strength Parameters
Authors: Chmielewski T. , Piotrowska M. 
Published: October 2019

AbstractThe paper deals with the variability of mechanical properties of EPSTAL steel rods produced in Polish steelworks, i.e. yield stress Re, tensile strength Rm, and elongation Agt. Our study is based on fundamental engineering static room-temperature tensile tests for large series specimens which have been made by manufacturers as the part of a factory quality control. Statistical analysis of these results shows that the stress-strain relationship of steel tensile tests should be described by a one-dimensional stochastic process, and three the most important mechanical parameters, i.e. the yield stress, tensile strength, and elongation by random variables. Based on the statistical elaboration of experimental data, it was found that the yield stress and tensile strength of steel rods produced in the years 2016 - 2017 had the coefficients of variation of less than 3%, and there is a reasonable basis for the manufacturer to increase the characteristic value of EPSTAL steel rods yield stress by a few percentages.
Study of the Admixtures Effect on Concrete Creep Using Bayesian Linear Regression
Authors: Zgheib E. , Raphael W. 
Published: October 2019

AbstractAdmixtures are commonly used nowadays in the mix composition of concrete. These additions affect concrete properties and performance especially creep deformations. This paper shows the effect of admixtures on creep of concrete. In fact, creep deformations have prejudicial consequences on concrete behaviour; an incorrect or inaccurate prediction leads to undesirable consequences in structures. Therefore, an accurate estimation of these deformations is mandatory. Moreover, design codes do not consider admixtures’ effect while predicting creep deformations, thus it is necessary to develop models that predict accurately creep deformations and consider the effect of admixtures. Using a large experimental database coming from international laboratories and research centres, this study aims to update the Eurocode 2 creep model by considering the type and percentage of admixtures using Bayesian Linear Regression method. The effect of two types of admixtures is presented in this paper; the water reducer and silica fume.

Authors: Wardani Surti 
Published: October 2019

Orasi politik (pidato) merupakan momen bagi seorang kandidat untuk bisa memperlihatkan kualitasnya baik sebagai pribadi (ramah, hangat, optimis, dan lain sebagainya), pemikir (lewat berbagai ide serta inovasi yang ditawarkan), maupun sebagai manager (kecakapan mengelola pemerintahan jika kelak terpilih sebagai presiden). Asumsi yang dibangun dalam penelitian ini adalah tidak maksimalnya pemanfaatan orasi politik (pidato) sebagai saluran komunikasi politik antara sang kandidat dengan konstituennya. Seharusnya, orasi politik bisa menjadi momentum antara kandidat dan pendukungnya untuk menyelesaikan ragam persoalan bangsa. Penelitian ini bertujuan untuk menganalisis orasi politik kedua calon presiden pada Pemilihan Presiden 2019. Pendekatan yang digunakan pada penelitian ini adalah pendekatan deskriptif kualitatif. Pengumpulan data dilakukan lewat studi literatur. Teknik analisis isi yang digunakan dilakukan terhadap berbagai dokumen, yang meliputi dokumentasi debat kandidat, berita pada portal media online serta orasi politik kedua kandidat pada Pemilihan Presiden 2019. Hasil penelitian menunjukkan bahwa (1) orasi politik yang disampaikan oleh Prabowo dan Jokowi cenderung menggeneralisir permasalahan hingga menimbulkan kontroversi; (2) strategi yang digunakan kedua kandidat politik ialah legitimasi dan delegitimasi; (3) kedua kandidat bisa memperlihatkan wajah “positif” dan “negatif” yang menjadi unsur penyeimbang sehingga konflik sosial tak mudah meletup di tengah masyarakat.Kata Kunci: Orasi politik, legitimasi, delegitimasi, Pilpres 2019 ABSTRACTPolitical oration (speech) is a good moment for candidate to be able to show his quality both as a person (friendly, warm, optimistic, etc.), thinker (through various ideas and innovations offered), and as a manager (ability to manage government if one is elected as president). The assumption built in this research is that the use of political speeches (speeches) is not optimal as a channel of political communication between the candidate and his constituents. Supposedly, political speeches can be a momentum between candidates and supporters to solve various national problems. This research aims to analyze the political speeches of the two presidential candidates in the 2019 Presidential Election. This research use desciptive qualitative approach. Data collection was carried out through literature studies. The content analysis technique used was performed on various documents, which included documentation of candidate debate, news on online media portal and political speeches of both candidates in the 2019 Presidential Election. The results showed that (1) political speeches delivered by Prabowo and Jokowi tended to generalize the problem and causing controversy; (2) the strategies used by the two political candidates are legitimacy and delegitimation; (3) both candidates can show a “positive” and “negative” face which is a balancing element so as to reduce social conflict.Keywords: political oration, legitimation, delegitimation, Presidential Election
