Мета. Розробити адаптивну систему вирощування овочів для зрошуваних умов східного Лісостепу України. Методи. Лабораторно-польовий стаціонарний дослід. Результати. За адаптивної системи вирощування біопотенційність (урожайність) основного біологічного об’єкту – овочевих рослин сортів вітчизняної селекції, які вирощують у біологізованій сівозміні, суттєво не знижується. Застосування високотоксичних препаратів за інтенсивної системи вирощування забезпечує надійний захист посівів овочевих культур від комплексу шкідливих організмів. Істотною перевагою адаптивних систем є зменшення хімічного навантаження в агроценозах овочевих культур. Якість овочевої продукції з адаптивної системи, як фактор конкурентоспроможності – не нижча, ніж за інтенсивної, біологізація сівозміни сприяла зниженню вмісту нітратів у продуктових органах. Економічна оцінка адаптивної системи вирощування овочів: досягнуто підвищення рівня рентабельності в цілому по сівозміні до 160 % (за інтенсивної системи – 121 %). Висновки. У східному Лісостепу України на чорноземі опідзоленому середньосуглинковому лучнуватому в умовах зрошення альтернативою інтенсивній системі вирощування овочевих культур може стати адаптивна система, основою якої є: біологізована сівозміна (з включенням люцерни, проміжних та ґрунтовкривних культур); безвідвальний обробіток ґрунту (хоча б на 50% площі); локальне внесення мінеральних добрив, гній (в одному полі), біологічні регулятори росту; інтегрований захист рослин (біологічні та малотоксичні препарати); сорти овочевих культур селекції ІОБ НААН. У середньому за роки досліджень урожайність овочевих культур, вирощених за адаптивної системи, була на рівні з інтенсивною у цибулі ріпчастої (відповідно 31,4 та 30, 1 т/га), моркви (відповідно 26,3 та 26,8 т/га) і капусти білоголової пізньостиглої (відповідно 37,0 та 37,6 т/га), або мала тенденцію до зменшення у томата (відповідно 38,9 та 41,0 т/га) і буряка столового (відповідно 51,8 та 55,7 т/га). Застосування адаптивної системи вирощування овочів, у порівнянні з інтенсивною, забезпечує підвищення рентабельності на 32 відносних %.
Stabilization of Crude Oil Contaminated Soils with Alkali-Activated Slag
Authors: Sadighi Hossein , Rowshanzamir Mohammad Ali
Published: August 2019

The high exposure of areas in the vicinity of oil plants and refineries to crude oil and oil product contaminations and the problems they cause for the physical expansion of these facilities underscore the importance of stabilization of oil-contaminated soils. Soil stabilization with cost-effective stabilizing agents is widely regarded as a simple and fast way of limiting the impacts of such contaminations. For decades, cement and lime have been the standard binders for soil remediation and stabilization applications, but with the increasing awareness about their environmental impact and the notion of sustainable development in general, there is now a growing interest in the use of cleaner alternatives based on new technologies for this purpose. In recent years, alkali-activated binders have been the subject of much interest because of their high strength and durability and limited environmental impacts. The soil treatment solution investigated in this study is the use of slag, which is a steel production byproduct mostly consisting of calcium and magnesium alumina silicates, in combination with two activators, namely sodium hydroxide and sodium silicate. Direct shear tests were performed on the crude oil contaminated soil specimens in order to determine the best alkali-activated designs and the effect of exposure time, slag content, and treatment time on the outcomes. The test results showed that adding 10% slag, 1.15% sodium silicate, and 1.61% sodium hydroxide (all by dry weight of soil) to the crude oil contaminated soil improved its cohesion and friction angle by 70% and 50% respectively.

Published: August 2019

The use of a finite element (FE) method and selection of the appropriate model to simulate soil elastoplastic behaviour has confirmed the importance and sensitivity of the soil properties on the accuracy when compared with experimental data. The properties of the filling soil play a significant role in determining levels of deformation and displacement of both the soil and subterranean structures when using the FE model simulation. This paper investigates the impact of the traffic load on the filling soil deformation when using the traditional method, one pipe in a trench, and a new method, two pipes in a single trench one over the other, for setting up a separate sewer system. The interaction between the buried pipes and the filling soils has been simulated using an elastoplastic FE model. A modified Drucker-Prager cap constitutive model was used to simulate the stress-strain behaviours of the soil. A series of laboratory tests were conducted to identify the elastoplastic properties of the composite soil used to bury the pipes. The FE models were calibrated using a physical lab model for testing the buried pipes under applied load. This allows the FE model to be confidently upgraded to a full-scale model. The pipe-soil interactions were found to be significantly influenced by the soil properties, the method of placing the pipes in the trench and the diameters of the buried pipes. The deformation of the surface soil was decreased by approximately 10% when using the new method of setting up the separate sewer.

Published: August 2019

Globalization always lead to various kinds of influences, both negative nor positive, on the national character. In Indonesia, globalization has caused a significant degradation of national character which ended by the poor national character of the Indonesia’s young generation. In order to minimalize this impact, the Indonesian government has launched a program, named State Defense Awareness Programme (Program Pembinaan Kesadaran Bela Negara), in order to perform the mental revolution program and building the national character of Indonesia’s young generation, which has influenced by the negative effect of globalization. But until now, the Indonesian citizens are still not convinced that State Defense Awareness Programme can be an appropriate means in building the national character of Indonesian citizens. This condition was supported by the emergence of negative stigma related to State Defense Awareness Programme, which ultimately reduces the level of people participation in the program. This article was written by using a systematic approach and contribution analysis method. The results of this study are expected to be a consideration for the Indonesian government and citizens in implementing and joining this program. Based on the analysis result, it can be concluded that State Defense Awareness Programme has a significant contribution towards national character building of Indonesia’s young generation. A comprehensive and integrated implementation of this program will produce citizens or state defense cadres who has highly character of nationalism, patriotism, solidarity, skill, collaboration, discipline, leadership and so on, especially for Indonesians who are born and grow up on border areas or foreign country and have experienced a significant shift of state defense awareness. This program will also produce resilient, militant, and nationally awareness citizens based on the State Defense, Pancasila values and the 1945 Constitution norms.

Preventing child sexual abuse and the use of child abuse images: the Prevention Project Dunkelfeld as an international perspective
Authors: Beier Klaus M.
Published: August 2019

Paedophilia—a sexual preference for the body scheme of pre-pubescent children—is defined as a disorder within the International Classification of Diseases (ICD) of the World Health Organization as well as within the Diagnostic and Statistical Manual of Mental Disorders (DSM) of the American Psychiatric Association. Contrary to popular belief, not all sex offenders who target children are paedophiles, and not all paedophiles commit sexual offences. But quite obviously paedophilia is an emotionally charged and controversial topic, which might be an explanation for putting it out of focus within the healthcare system. Mental health professionals are mainly (and worldwide) not well trained in terms of assessment methods and intervention techniques available to develop and implement effective policies and practices. This presents an obstacle for prevention, in that proactive strategies to protect children from child sexual abuse and sexual exploitation by online offences, such as the consumption or distribution of child abusive images (so-called child pornography), which emphasises the internationally relevant dimension of the issue. The article will address key concerns and questions in dealing with this clinically relevant population, offer insights into a primary prevention approach developed in Germany, and discuss the situation on a European level.
Leadership, betrayal, and institutional integrity
Authors: Krantz James
Published: August 2019

When the requirements of an institution’s mission collides with the hopes, needs, and expectations of its people, leaders can face a painful choice. Either corrupt the institution by compromising its mission or betray those whose commitment and loyalty are essential. This tribute to Wesley Carr explores the notion of “virtuous betrayal” that was developed in an earlier paper and links it to issues of institutional integrity.
Resistance and solidarity: organising for women’s human rights
Authors: Williams Barbara
Published: August 2019

Using Lacanian, feminist, and organisational theory, this article explores the problem and question of violence against women and gender justice. In it, I argue that this violence and degradation against women is a fact, while simultaneously linking the notion of gender and its uncertain historicity to the traumatic discursive and psychical nature of en/gendering and to what this might mean for an organisation whose mission is gender justice. The inevitable push to settle the meanings of women and leadership marks the impossible desire to know. I highlight the work of an established feminist international women’s rights and gender-justice organisation and its efforts to resist this push to settle
meanings and the related implications and challenges this may have on their shared-leadership model.
Building the identity of teaching and research of HR management in a faculty of Economics and Business Administration: a socio-analytical exploration of its history
Authors: Aguirre Eduardo Acuña
Published: August 2019

This article is concerned with the recovery and discovery of conscious and unconscious meanings in the construction of the identity of the Human Resource Management (HRM) discipline at the Faculty of Economics and Business Administration, Universidad de Chile. The article is based on a research exploring the role of collective memory in the construction of that identity, from its inception in 1958 until 2017. A socio-analytical approach was applied to understand the dynamics implied in the construction of the identity of HRM. The results of the research show the existence of silenced meanings about that construction as a consequence of an unconscious political memory operating at the faculty that restricted the access and understanding of unexamined institutional knowledge. Such censorship is thought to be associated with the transformations that
occurred in Chilean society and the faculty before and after the coup d’état that took place in 1973.

Published: August 2019

A large number of entrepreneurs who grow in society can be an influencer of the progress of the economy of a nation. This is because the increase of entrepreneurs can lead poverty and unemployment to be minimized. To reach this stage, training is needed to improve the ability of the society to be more creative and innovative. This is as the objectives implemented in the Young Entrepreneur Academy (YEA) to create training programs that focus on creating entrepreneurs. The purpose of this study was to find out the success of YEA in creating prospective entrepreneurs. Furthermore, a descriptive qualitative approach was applied in this study, while, the data in this study were collected through interviews, observation, and documentation. The researchers found that the YEA has various planning programs with a vision to create prospective entrepreneurs who are adapted to the development of the business world. Thus, the YEA is more focused on carrying out training in practice than just a theory. The conclusion is the YEA makes the Experiential Learning program not to create prospective job seekers but aims at creating the candidates for opening jobs.

Su contenido abarca los resultados de la investigación sobre las propiedades físico-químicas de distintas dosificaciones cuyo contenido de árido se sustituyó parcialmente por GCR en distintos porcentajes. Además se muestra la evaluación de las propiedades mecánicas de las dosificaciones en estudio con las muestras convencionales mediante ensayos de absorción, flexo-tracción y compresión. Lo anterior expuesto permitió determinar que se puede brindar una alternativa diferente para el reciclaje ya que el grano de caucho puede ser usado como posible sustituto de agregado fino, debido a que se obtuvieron adoquines ecológicos con 5, 7 y 9 porciento en sustitución de arena, que presentaron una absorción y resistencia a la flexión por encima de lo exigido por la (NTC 2017) norma nacional Colombiana
In silico analysis of phag-like protein in Ralstonia Euthropa H16, potentially involved in polyhydroxyalkanoates synthesis
Authors: Uribe Acosta Melissa , Villa Restrepo Andrés Felipe
Published: August 2019

Polyhydroxyalkanoates (PHA) are synthesised by bacteria as carbon storage material. The protein PhaG directs carbon from non-related carbon sources such as glycerol, metabolised through fatty acid de novo synthesis (FAS) pathway, with PHA synthesis. The gene that codifies for this protein has not yet been found in the genome of Ralstonia eutropha H16, a model organism. By bioinformatic comparison to already known PhaG proteins, a PhaG-like protein was found codified by gene H16_A0147 and presence of the gene was preliminary confirmed by PCR. This is the first study that shows the presence and characteristics of a PhaG-like protein in R. eutropha H16 and represents the first step for the identification of a connection between FAS and PHA pathways in this model bacterium. Further gene deletion and enzymatic activity studies are necessary to confirm this potential relationship, which could improve industrial PHA production and utilisation of agro-industrial residues such as glycerol.
3D+T dense motion trajectories as kinematics primitives to recognize gestures on depth video sequences
Authors: Martínez Carrillo Fabio , Castillo Fabián , Bautista Lola
Published: August 2019

RGB-D sensors have allowed attacking many classical problems in computer vision such as segmentation, scene representations and human interaction, among many others. Regarding motion characterization, typical RGB-D strategies are limited to namely analyze global shape changes and capture scene flow fields to describe local motions in depth sequences. Nevertheless, such strategies only recover motion information among a couple of frames, limiting the analysis of coherent large displacements along time. This work presents a novel strategy to compute 3D+t dense and long motion trajectories as fundamental kinematic primitives to represent video sequences. Each motion trajectory models kinematic words primitives that together can describe complex gestures developed along videos. Such kinematic words were processed into a bag-of-kinematic-words framework to obtain an occurrence video descriptor. The novel video descriptor based on 3D+t motion trajectories achieved an average accuracy of 80% in a dataset of 5 gestures and 100 videos.

Special attention is paid to the problem of close dissociation constants and in particular to the possibility of the inversion of constants, for example,  Ka1 < Ka2 (or pKa1 > pKa2) for equilibria H2A ⇄ HA– ⇄  A2–, H2A+ ⇄ HA ⇄ A– or H2A2+ ⇄ HA+ ⇄A.  Equilibria of inorganic and organic acids are successively considered. Some cases of inversion are considered. In particular, such relations are sometimes observed for fluorescein and phthalein compounds, and for porphyrins. In the last case, as well as in some other systems the acid-base reactions proceed relatively slow. An overview of approaches to estimation of the Ka1/ Ka2 ratio is presented. Namely, these approaches use the concepts of the detailed equilibrium scheme, dissociation microconstants, statistical and electrostatic factors, and the influence of intra-molecular hydrogen bonds. The variety of reasons for additional stabilization of the forms H2A (or H2A+, or H2A2+) and A2– (or A–, or A) and destabilization of the form HA– (or HA, or HA+) is regarded, including salt effects and ionic association. Peculiarities of stepwise protolytic equilibria of macrocyclic compounds, such as calixarenes, porphyrins, and cryptands, are considered. Dispersed systems such as polyelectrolytes, micelles of functionalized surfactants, monolayers, silica and modified silica, other oxides, nanodiamonds decorated by carboxylic groups, represent a peculiar type of polyprotic acids. In this case, a “spectrum” of  pKa  values appears because of influence of ionized functional groups on the properties of un-dissociated ones. It was demonstrated that such unusual ratio of constants, Ka1 < Ka2, may be caused by a set of factors, among which most important are (i) the tautomerism in true solutions and (ii) selective binding of different equilibrium forms in organized solutions, i.e., in micellar solutions of surfactants, suspensions of phospholipid liposomes, and related systems.

In this work, we have carried out a research which aimed to obtain complex nanoparticles of noble metals Au + Ag in the form of bimetallic alloys. Bimetallic nanoparticles were synthesized directly in a liquid-crystalline cadmium caprylate melt in an argon atmosphere in the temperature range of mesophase existence by the simultaneous chemical reduction of cations of gold (Au3+) and silver (Ag+) from their compounds, tetrachloroaurate acid (H[AuCl4]×3Н2О) and silver  nitrate AgNO3, respectively.

  The effect of synthesis duration (3 and 5 hours) on the spectral behavior of binary nanoparticles have been studied. It has been shown that when the synthesis duration is 3 h, mainly homogeneous bimetallic alloys are obtained, and when it is 5 h, both homogeneous and gradient alloys can be obtained. The absorption spectra of homogeneous alloys are characterized by the presence of one surface plasmon resonance (SPR) peak, which occupies an intermediate position relative to the SPR peaks for monometallic nanoparticles, i.e. between 425 and 560 nm. When forming heterogeneous alloys, which are formed in the molar ratio range where the amount of silver ions predominates, the absorption spectra exhibit two SPR peaks which relate to nanoparticles with different metallic silver content. The formation of metallic nanoparticles containing different metals may be due both to the different mobility of noble metals ions in the liquid crystal matrix and to the different rate of rearrangement of metals in the new formed heteronanoparticle.

  It has been found by electron spectroscopy and transmission electron microscopy that the nanoparticles in this matrix have mostly a spherical shape with a mean diameter of 15 nm. The possibility of the fine control of the position of SPR peak of bimetallic nanoparticles in a liquid crystal matrix over a wide optical range   of  422–580 nm is shown.

Ceramic materials CaCu3Ti4O12 were synthesized by solid-phase reactions technique. The sequence of chemical reactions during the synthesis has been determined. Phase CaCu3Ti4O12 appears at 700 °C. At 800 – 900 °C, the intermediate phases CaTiO3, CuTiO3 and Ca3Ti2O7 are formed. Calcium and copper titanates, CaTiO3 and CuTiO3 interact to form CaCu3Ti4O12. Ca3Ti2O7 phase with pyrochlore structure is stable and prevent the formation of final product, CaCu3Ti4O12. A method for the synthesis of CaCu3Ti4O12 by solid-state reactions technique from previously synthesized CaTiO3 (at 1050 °С) and CuTiO3 (at 950  °С), taken in a molar ratio of 1:3, is proposed. This method give the possibility to avoid the appearance of an undesirable Ca3Ti2O7 phase with the pyrochlore structure and to reduce the content of free copper oxide to value less than 0.5 mol.%. In addition, instead of the copper oxide, which is usually used in solid-state reaction technique, the chemically more active form of the copper-containing reagent, CuCO3∙Cu(OН)2 were used. This reduce the synthesis time of the intermediate CuTiO3. The crystal structure, chemical composition, microstructure and electrophysical parameters of ceramics have been analyzed. The synthesized ceramics CaCu3Ti4O12 is cubic body-centered (space group Im-3) with the unit cell parameter a = 7.3932 Å, which agreed with the literature data. The calculated tolerance factor of CaCu3Ti4O12, t = 0.7626 is not sufficient for a stabilization of peroskite ABO3 structure; that is why the crystal structure of this compound contains 3 different cation sites: dodecahedral (Ca2+), octahedral (Ti4+), tetrahedral (Cu2+). At 1150 °C, the density of CaCu3Ti4O12 ceramic sintered has a maximum (90% of the theoretical density). At infra-low frequencies (10-3 Hz), the dielectric constant (e) reaches record values of 107, however, dielectric losses (tg d) up to 10 were observed. In the frequency range 10-3 - 105 Hz the value of ɛ exceeds 104; and at 105 Hz minimum of the dielectric losses (tg δ ~ 0.1) is observed. A comparative analysis of methods for the synthesis of CaCu3Ti4O12 shows that the synthesis conditions of material of the same chemical composition can be crucial in creating high dense ceramic with uniform grains, high dielectric constant and low dielectric losses in a wide frequency range.
Scalable Bi-Directional SMA-Based Rotational Actuator

In industrial applications, rotatory motions and torques are often needed. State-of-the-art actuators are based on either combustion engines, electro-motors, hydraulic, or pneumatic machines. The main disadvantages are the construction space, the high weight, and a large amount of needed peripheral devices. To overcome these limitations, compact and light-weight actuator systems can be built by using shape memory alloys (SMAs), which are known for their superior energy density. In this paper, the development of a scalable bi-directional rotational actuator based on SMA wires is presented. The scalability was based on a modular design, which allowed the actuator to be adapted to various application specifications by customizing the rotational angle and the output torque. On the mechanical side, each module enabled a small rotatory motion, which added up to the total angle of the actuator. The SMA wires were arranged in an agonist-antagonist configuration to provide active rotation in both directions. The presented prototype achieved a total rotation of 100°. The modularity of the mechanical concept is also reflected in the electronics, which is discussed in this paper as well. This consideration allows the electronics to be adapted to the mechanics with minimal changes. As a result, a prototype, including the presented mechanical and electronic design, is reported in this study.

Using cover crops in fallow periods of crop production is an important management tool for reducing nitrate leaching and therefore improving nitrogen availability for subsequent crops. We estimated the short-term effect of five cover crop species on the yield of successive spring barley (Hordeum vulgare L.) for two years in Estonia. The cover crop species used in the study were winter rye (Secale cereale L.), winter turnip rape (Brassica rapa spp. oleifera L.), forage radish (Raphanus sativus L. var. longipinnatus), hairy vetch (Vicia villosa Roth), and berseem clover (Trifolium alexandrinum L.). The results indicated that out of the five tested cover crops, forage radish and hairy vetch increased the yield of subsequent spring barley, whereas the other cover crops had no effect on barley yield. All cover crop species had low C:N ratios (11–17), suggesting that nitrogen (N) was available for barley early in the spring.
Field Spectroscopy: A Non-Destructive Technique for Estimating Water Status in Vineyards

Water status controls plant physiology and is key to managing vineyard grape quality and yield. Water status is usually estimated by leaf water potential (LWP), which is measured using a pressure chamber; however, this method is difficult, time-consuming, and error-prone. While traditional spectral methods based on leaf reflectance are faster and non-destructive, most are based on vegetation indices derived from satellite imagery (and so only take into account discrete bandwidths) and do not take full advantage of modern hyperspectral sensors that capture spectral reflectance for thousands of wavelengths. We used partial least squares regression (PLSR) to predict LWP from reflectance values (wavelength 350–2500 nm) captured with a field spectroradiometer. We first identified wavelength ranges that minimized regression error. We then tested several common data pre-processing methods to analyze the impact on PLSR prediction precision, finding that derivative pre-processing increased the determination coefficients of our models and reduced root mean squared error (RMSE). The models fitted with raw data obtained their best results at around 1450 nm, while the models with derivative pre-processed achieved their best estimates at 826 nm and 1520 nm.

Intermediate wheatgrass (IWG, Thinopyrum intermedium, (Host) Barkworth & D.R. Dewey subsp. intermedium, 2n = 6x = 42) is a novel perennial crop currently undergoing domestication efforts. It offers remarkable ecosystem services and yields higher relative to other perennial grain crops. While IWG is mostly resistant to Fusarium head blight (FHB), identifying genomic regions associated with resistance will help protect the crop from potential disease epidemics. An IWG biparental population of 108 individuals was developed by crossing parents differing in their response to FHB and bacterial leaf streak (BLS). The population was screened for disease reaction over three years using isolates collected from IWG plants in St. Paul, Minnesota, USA. Linkage maps representing the 21 IWG chromosomes were constructed from 4622 Single Nucleotide Polymorphism (SNP) markers, with one SNP at every 0.74 cM. Interval mapping identified 15 quantitative trait loci (QTL) associated with FHB resistance and 11 with BLS resistance. Models with two or three QTL combinations reduced FHB disease severity by up to 15%, and BLS by up to 17%. When markers associated with FHB resistance were used as cofactors in genomic selection models, trait predictive ability improved by 24–125%. These genomic regions and genetic markers associated with FHB and BLS resistance can also be used to safeguard annual cereal grains through gene introgression and selective breeding.
