Published: December 2019

Dynamics of total phenolic compounds content in the leaves of four cultivars and one subspecies of Olea europaea L. were studied during the cold periods of 2016-2019 years on the Southern Coast of the Crimea. The concentration of phenolic substances ranged from 642 to 1332 mg/100 g of fresh biomass. It was found out that the content of phenolic compounds depended on weather conditions during a particular cold period and it did not almost depend of the degree of frost resistance of the studied genotypes.

The article provides data on a comparative study of the content and component composition of essential oil, the total content of antioxidants and flavonoids of two cultivars and two promising cultivar samples of Italian strawflower ( Helichrysum italicum (Roth) G. Don) grown on the Southern Coast of the Crimea in the collection of aromatic and medicinal plants of the Nikitsky Botanical Gardens. It has been found that the content of essential oil in the green weight of top of H. italicum varies from 0.1% of the wet weight (‘Crystal’ cultivar) to 0.2 (cultivar No. 5). The main components of ‘VIM’ cultivar essential oil are α-pinene and D-limonene, of ‘Crystal’ cultivar is neril acetate, of the sample No. 5 is α-pinene and rosiforiol, of the sample No. 158 is neryl acetate and γ-turmeric. A significant relative content of β-diketones (38%) in the essential oil of ‘Crystal’ cultivar was noted. The greatest amount of antioxidants (2.59 mg / g (in conversion to quercetin) and flavonoids (0.366%) in the inflorescences of Italian strawflower ‘VIM’ cultivar is contained in the budding phase. The results of chromatographic analysis prove the presence of 4 phenolic substances in the inflorescences of Italian strawflower. UV-spectra of alcohol solutions of the studied raw materials had a maximum absorption at a wavelength of 418 ± 2nm. Quantitative determination of flavonoids by differential spectroscopy calculated as isosalipurposide showed that the content of flavonoids in inflorescences varies from 0.262% to 0.366% depending on a cultivar and a phase of vegetation.

Newspaper industry in fact is decreasing from 2006 until right now. Shifting behavior of their customer is becoming newspaper company problem to survive in this industry. Newspaper industry should shift their business into e-newspaper if they did not want to end up like music distributor industry. Even though, e-newspaper business model itself is not easy to be adapt. In fact, there are a lot of newspaper company who already failed to implement e-newspaper. Most of newspaper company treat e-newspaper only as their other distribution channel. It was the wrong concept if they want to develop e-newspaper and run it as the substitution of traditional newspaper. Revenue stream become the main concern in e-newspaper since it is difficult to create sustainable revenue stream. Result of the research is in order to create sustainable revenue stream, newspaper company should take a look at their resources and capabilities first. Value chain analysis is used to grab the potency of Pikiran Rakyat and make it as value proposition concerning e-newspaper in order to create revenue stream through e-newspaper. Last, business model canvas is used in order to map the proposed business model. In the end, e-newspaper Pikiran Rakyat has various revenue stream that could be used

NARRATIVAS (AUTO)BIOGRÁFICAS SOBRE AS INFÂNCIAS E SEUS LUGARES NA FORMAÇÃO DOCENTE
Authors: Pellenz Irgang Silvania Regina , Fortes de Oliveira Valeska
Published: December 2019

Quando nos propomos a pesquisar a vida do professor, desenvolvemos uma escuta sensível de sua história, de seus saberes e os caminhos construídos no decorrer de sua formação docente. Foi por meio disto que desenvolvemos uma proposta de pesquisa-formação com três professoras de Educação Infantil, egressas do curso de Pedagogia, da Universidade Federal de Santa Maria (UFSM)/RS, com o intuito de nos aproximarmos de seus imaginários e narrativas (auto)biográficas sobre o lugar da infância na formação docente. Utilizamos uma pesquisa de abordagem qualitativa no processo de formação/autoformação que se baseia em referenciais teórico-metodológicos que viabilizam a discussão acerca da memória, história de vida e narrativas (auto)biográficas construídas em duas “experiências formadoras” intituladas “Baú de memória: lembranças da formação” e “Álbum de infâncias”. Cada professora trouxe objetos pessoais guardados em seus “baús formativos” e narraram os sentidos e os significados em relação à infância na formação inicial e na experiência profissional, a partir de suas “recordações-referências”. Na atualidade, os estudos sobre a infância transitam por diferentes áreas do conhecimento; conhecer o que os profissionais da Pedagogia compreendem sobre a infância é relevante para problematizar outras discussões no âmbito da educação. Assim, Christine Josso foi um dos aportes teóricos que nos permitiu vivenciar e repensar sobre as infâncias vividas, proporcionadas, (re)construídas com as crianças e nos debates em espaços acadêmicos e de formação. Isso fez com que pudéssemos refletir sobre o lugar que cada uma vem dando à infância em sua formação docente.

АГРОПРОМИСЛОВА ТОРГІВЛЯ ТА Е.С. РИНОК: МОЖЛИВОСТІ ТА ВИКЛИКИ МОЛДОВИ
Authors: Cimpoies Liliana
Published: December 2019

Метою даного дослідження є оцінка розвитку потоків сільськогосподарської та продовольчої торгівлі Молдови на ринок ЄС. Таким чином, аналізуються основні зміни і тенденції в структурі агропродовольчої торгівлі і на ринках збуту. Дослідження засноване на аналізі вторинних даних, наданих Національним Бюро Статистики. Розглянуті дані відносяться до 2012-2017 рр. Позитивним результатом лібералізації торгівлі стало збільшення обсягів агропродовольчого експорту Молдови, особливо з точки зору спеціалізації і концентрації виробництва та диверсифікації географічного розподілу. Ще один позитивний результат - зниження залежності від традиційних ринків. Цей факт зумовив збільшення як якості, так і різноманітності товарів, що експортуються. Завдяки угоді про вільну торгівлю спостерігається збільшення торговельних потоків з ЕСю Агропродовольчий ринок важливий для стабілізації національної економіки, оскільки він вносить цінний внесок у ВВП. Таким чином, важливо, щоб уряд підтримував модернізацію агропродовольчого сектору та стимулювало залучення інвестицій, що сприятиме його подальшій орієнтації.

METHOD FOR REAL TIME FACE RECOGNITION APPLICATION IN UNMANNED AERIAL VEHICLES
Authors: Jurevičius Romualdas , Goranin Nikolaj , Janulevičius Justinas , Nugaras Justas , Suzdalev Ivan , Lapusinskij Aleksandr
Published: December 2019

Newly evolving threats to public safety and security, related to attacks in public spaces, are catching the attention of both law enforcement and the general public. Such threats range from the emotional misbehaviour of sports fans in sports venues to well-planned terrorist attacks. Moreover, tools are needed to assist in the search for wanted persons. Static solutions, such as closed circuit television (CCTV), exist, but there is a need for a highly-portable, on-demand solution. Unmanned aerial vehicles (UAVs) have evolved drastically over the past decade. Developments are observed not only with regards to flight mechanisms and extended flight times but also in the imaging and image stabilization capabilities. Although different methods for facial recognition have existed for some time, dealing with imaging from a moving source to detect the faces in the crowd and compare them to an existing face database is a scientific problem that requires a complex solution. This paper deals with real-time face recognition in the crowd using unmanned aerial vehicles. Face recognition was performed using OpenCV and Dlib libraries.
SN Ia Explosions from Hybrid Carbon–Oxygen–Neon White Dwarf Progenitors that Have Mixed during Cooling
Authors: Augustine Carlyn N. , Willcox Donald E. , Brooks Jared , Townsley Dean M. , Calder Alan C.
Published: December 2019

The creation of “hybrid” white dwarfs, made of a C–O core within an O–Ne shell has been proposed, and studies indicate that ignition in the C-rich central region makes these viable progenitors for thermonuclear (type Ia) supernovae. Recent work found that the C–O core is mixed with the surrounding O–Ne as the white dwarf cools prior to accretion, which results in lower central C fractions in the massive progenitor than previously assumed. To further investigate the efficacy of hybrid white dwarfs as progenitors of thermonuclear supernovae, we performed simulations of thermonuclear supernovae from a new series of hybrid progenitors that include the effects of mixing during cooling. The progenitor white dwarf model was constructed with the one-dimensional stellar evolution code Modules for Experiments in Stellar Astrophysics (MESA) and represented a star evolved through the phase of unstable interior mixing followed by accretion until it reached conditions for the ignition of carbon burning. This MESA model was then mapped to a two-dimensional initial condition for explosions simulated with FLASH. For comparison, similar simulations were performed for a traditional C–O progenitor white dwarf. By comparing the yields of the explosions, we find that, as with earlier studies, the lower C abundance in the hybrid progenitor compared to the traditional C–O progenitor leads to a lower average yield of

. Although the unmixed hybrid white dwarf showed a similar decrement also in total iron-group yield, the mixed case does not and produces a smaller fraction of iron-group elements in the form of

. We attribute this to the higher central density required for ignition and the location, center or off-center, of deflagration ignition.
Exact Analytical Expression for the Synchrotron Radiation Spectrum in the Gaussian Turbulent Magnetic Field
Authors: Derishev Evgeny , Aharonian Felix
Published: December 2019

We demonstrate that the exact solution for the spectrum of synchrotron radiation from an isotropic population of monoenergetic electrons in a turbulent magnetic field with a Gaussian distribution of local field strengths can be expressed in the simple analytic form:

, where

We use this expression to find the approximate synchrotron spectra for power-law electron distributions with

-type high-energy cutoff; the resulting synchrotron spectrum has the exponential cutoff factor with a frequency raised to the 2β/(3β + 4) power in the exponent. For the power-law electron distribution without a high-energy cutoff, we find the coefficient a

m
as a function of the power-law index, which results in the exact expression for the synchrotron spectrum when using the monochromatic (i.e., each electron radiates at the frequency

) approximation.
The Progenitors of Calcium-strong Transients
Authors: Shen Ken J. , Quataert Eliot , Pakmor Rüdiger
Published: December 2019

A new class of faint, spectroscopically peculiar transients has emerged in the last decade. We term these events “calcium-strong transients” (CaSTs) because of their atypically high calcium-to-oxygen nebular line ratios. Previous studies have struggled to deduce the identity of their progenitors, due to a combination of their extremely extended radial distributions with respect to their host galaxies and their relatively high rate of occurrence. In this work, we find that the CaST radial distribution is consistent with the radial distribution of two populations of stars: old (ages >5 Gyr), low-metallicity (Z/Z
⊙ < 0.3) stars, and globular clusters. While no obvious progenitor scenario arises from considering old, metal-poor stars, the alternative production site of globular clusters leads us to narrow down the list of possible candidates to three binary scenarios: mergers of helium and oxygen/neon white dwarfs; tidal disruptions of helium white dwarfs by neutron stars; and stable accretion from low-mass helium-burning stars onto white dwarfs. While rare in the field, these binary systems can be formed dynamically at much higher rates in globular clusters. Subsequent binary hardening both increases their interaction rate and ejects them from their parent globular clusters prior to mass transfer contact. Their production in, and ejection from, globular clusters may explain their radial distribution and the absence of globular clusters at their explosion site. This model predicts a currently undiscovered high rate of CaSTs in nuclear star clusters. Alternatively, an undetermined progenitor scenario involving old, low-metallicity stars may instead hold the key to understanding CaSTs.
A Kinematic Shift of the C iv Broad Absorption Line in Quasar SDSS J120819.29+035559.4
Authors: Lu 陆 Wei-Jian 伟坚 , Lin 林 Ying-Ru 樱如
Published: December 2019

We report the kinematic shift of the C iv broad absorption line (BAL) in quasar SDSS J120819.29+035559.4 (hereafter J1208+0355). This quasar shows two BAL systems, including a blue component of system A at ∼23,500 km s−1 that shows a kinematic shift of 1166 ± 65 km s−1, and a red component of system B at ∼7000 km s−1 that can be decomposed into several narrow absorption lines (NALs). First, we confirm that the most likely cause for the equivalent width variations of the absorption lines (at least for system B) in J1208+0355 is the ionization change scenario as a response to the changes in the ionization continuum according to the following observational factors: (1) coordinated multiple absorption lines strengthening; (2) the continuum flux shows an obvious weakening. Second, we find line-locking phenomena from the blended NALs within system B, indicating that these outflow clouds are driven by a radiative force caused by resonance lines. The above two research aspects convincingly reveal that the BAL outflows of J1208+0355 are affected by the background radiation energy. Therefore, we infer that the kinematic shift shown in system A may be produced by actual line-of-sight acceleration of the outflow clouds, which is driven by radiation pressure from the background light source.

Quasars at early redshifts (z > 6) with companion galaxies offer unique insights into the growth and evolution of the first supermassive black holes. Here, we report on a 150 ks Chandra observation of PSO J308.0416−21.2339, a z = 6.23 quasar with a merging companion galaxy identified in [C ii] and rest-frame UV emission. With

net counts, we find that PSO J308.0416−21.2339 is powerful (

in rest-frame 2.0–10.0 keV) yet soft (spectral power-law index

and optical-to-X-ray slope α
OX = −1.41 ± 0.11). In addition, we detect three hard-energy photons 2.″0 to the west of the main quasar, cospatial with the brightest UV emission of the merging companion. As no soft-energy photons are detected in the same area, this is potentially indicative of a highly obscured source. With conservative assumptions, and accounting for both background fluctuations and the extended wings of the quasar’s emission, these photons only have a probability P = 0.021 of happening by chance. If confirmed by deeper observations, this system is the first high-redshift quasar and companion individually detected in X-rays and is likely a dual active galactic nucleus.
Transit Signatures of Inhomogeneous Clouds on Hot Jupiters: Insights from Microphysical Cloud Modeling
Authors: Powell Diana , Louden Tom , Kreidberg Laura , Zhang Xi , Gao Peter , Parmentier Vivien
Published: December 2019

We determine the observability in transmission of inhomogeneous cloud cover on the limbs of hot Jupiters through post-processing a general circulation model to include cloud distributions computed using a cloud microphysics model. We find that both the east and west limbs often form clouds, but that the different properties of these clouds enhance the limb-to-limb differences compared to the clear case. Using the James Webb Space Telescope, it should be possible to detect the presence of cloud inhomogeneities by comparing the shape of the transit light curve at multiple wavelengths because inhomogeneous clouds impart a characteristic, wavelength-dependent signature. This method is statistically robust even with limited wavelength coverage, uncertainty on limb-darkening coefficients, and imprecise transit times. We predict that the short-wavelength slope varies strongly with temperature. The hot limbs of the hottest planets form higher-altitude clouds composed of smaller particles, leading to a strong Rayleigh slope. The near-infrared spectral features of clouds are almost always detectable, even when no spectral slope is visible in the optical. In some of our models a spectral window between 5 and 9 μm can be used to probe through the clouds and detect chemical spectral features. Our cloud particle size distributions are not lognormal and differ from species to species. Using the area- or mass-weighted particle size significantly alters the relative strength of the cloud spectral features compared to using the predicted size distribution. Finally, the cloud content of a given planet is sensitive to a species’ desorption energy and contact angle, two parameters that could be constrained experimentally in the future.
Viral and Host Factors are Related to the Progression of HIV Diseases in Mimika, Papua
Authors: Widiyanti Mirna , Hadi Moch Irfan
Published: December 2019

BACKGROUND: Papua has a high cumulative number of HIV, which has expanded epidemic status with the most risk factors are heterosexuals.
AIM: This study aims to determine factors associated with HIV disease progression include host and viral factors.
METHODS: Eighty-four subjects recruited in Rumah Sakit Mitra Masyarakat (RSMM) VCT’s laboratory, interviewed with questionnaires and also did laboratory examinations. HIV-1 subtypes were identified using RT-PCR, nested PCR and sequencing. Then, CD4+ data is checked using PIMA Analyzer. Demographic and clinical data obtained from the patient's medical record. After collected, data were analysed using Fisher's exact test.
RESULTS: The results showed two factors that influence the progression of HIV disease were HIV subtypes (p = 0.002) and Body Mass Index (p = 0.033). The HIV-1 subtype also correlated with CD4+ levels with a value of p = 0.04.
CONCLUSION: HIV-1 subtype correlates with HIV progression, so it is necessary to develop HIV/AIDS management strategies and clinical counselling.
A relação entre o indivíduo pós-moderno, o consumo e a internet das coisas
Authors: Sergl Marcos Júlio , Cunha Grace
Published: December 2019

Este artigo aborda concepções que estão em constante mudança no indivíduo, visto como uma figura que, assim como a tecnologia, apresenta transformações contínuas e rápidas em suas relações pessoais e agora até mesmo com objetos, tendo a perspectiva da Internet das Coisas, que surgiu como uma inovação para facilitar a vida das pessoas em uma sociedade pós-moderna caracterizada pelo consumismo. Atentos a esse panorama, nosso objetivo é investigar o pós-modernismo com vistas às mutações do sujeito e seus reflexos sobre o consumo e as novas tecnologias, tendo fundamentação em teóricos que se dedicam à análise deste universo: Bauman (1998, 2001 e 2007), Castells (2003), Giddens (1991), Hall (2011), Harvey (2000), Lemos (2002 e 2013), Levy (2010), Santaella (2003 e 2013) e Silva (2001).  O estudo é relevante a partir do momento que refletimos no quanto as modernas tecnologias de informação e comunicação reconfiguram as sociedades em diversos aspectos, como o cultural, o social e o comunicacional.
Trends and biases in scientific literature about marmosets, genus Callithrix (Primates, Callitrichidae): biodiversity and conservation perspectives
Authors: Hannibal Wellington , Renon Polla , Figueiredo Valquiria Vilalba , Oliveira Roniel Freitas , Moreno Antonio Eduardo , Martinez Romari Alejandra
Published: December 2019

Marmosets of the genus Callithrix are small-bodied platyrrhines, endemic to Brazil. In the last 30 years, there has been a constant interest in studying their biology, ecology and conservation. In this study, we compiled a systematic review to evaluate the trends and advances of marmoset research, from biodiversity and conservation perspectives. We searched for articles published in peer-reviewed journals within the main academic search engines, using the keywords “marmoset” OR “sagui” OR “Callithrix”. We found 68 published articles with a focus on biodiversity and conservation. The number of articles has increased over the years, most of them consisting of research from the Atlantic Forest biome. Callithrix penicillata (26 articles) and C. jacchus (21) were the most studied species. The number of studies was associated with the species’ geographical distribution. From a conservation perspective, the most threatened species showed the narrowest geographical distribution, a lower number of studies and, on average, a smaller protected area size. We concluded that trends and biases in biodiversity and conservation scientific literature of Callithrix are directly and indirectly associated with its geographical distribution. Species with wide geographical distribution are more studied, better known and protected. We highlight that the major effort of studies must be towards marmoset populations from the transition region of the Atlantic Forest-Cerrado and Caatinga biomes, and on threatened species within narrow geographical ranges.
This is not an essay about Trump
Authors: Grossberg Lawrence
Published: December 2019

This essay rejects efforts to understand the political field in the US as a war between two easily identified camps. It begins to think about the rise of the reactionary right (and Trump's place in it) by considering some of the stakes in play and strategies at work. Drawing on Gramsci's
notion of organic crises, it considers how such crises are being constructed, deployed and contested. It argues for the need to understand the ways in which the reactionary right has 'weaponised' and affectively managed the chaos of the overwhelming heterogeneity of the fields of political
struggles.
Religion, the secular and the left
Authors: Grayson Deborah , Walker Tamanda
Published: December 2019

This article outlines four common ways that religion and faith are managed within left-wing organising. The first (indifference) sees 'religion' and 'faith' as a set of traditional practices that will naturally disappear as modernity prevails. The second (hostility) sees religion in
terms of oppressive institutions which need to be excised from public life. The third (limited welcome) takes religion as a racial category, highlighting links between Christian-Secular supremacy and colonial domination, but does not engage with religious content. The fourth (incorporation)
recognises that spiritual practices can sustain collectives in effectively challenging oppression. These approaches are discussed through two contrasting examples of leftist organising. The first is Southall Black Sisters, for whom challenging patriarchy includes challenging its expression
in religious institutions, and secular spaces are seen as a necessary part of creating collectives. The second is the role of spirituality and religion in community responses to the Grenfell fire – in particular the shared walking in silence; this has been crucial to the community's
ability to maintain strength and experience solidarity in the face of incredible and ongoing injustice. In trying to understand how the left should go about building solidarities and alliances, the authors assert the value of localised and contingent readings of 'religion' and 'the secular'.
Babies and bathwaters: attachment, neuroscience, evolution and the left
Authors: Music Graham
Published: December 2019

This article challenges thinkers and activists on the left who are over-suspicious of ideas heralding from disciplines such as interpersonal neurobiology, attachment theory, developmental psychology, and perhaps especially, evolutionary theory. Although scepticism is frequently warranted,
especially as such discourses are often co-opted for neoliberal or far right ends, there is much in all of them that melds well with critiques of hegemonic social orders, providing potential fuel for those working for social change. Much work, for example that of Amy Cuddy, can be interpreted
both conservatively and progressively. Work from within an attachment theory paradigm can play a crucial part in the battle of ideas: it has a huge amount to teach about how to create a more humane and egalitarian world, and in countering neoliberal beliefs that humans are innately primarily
aggressive, competitive or selfish, or have selfish genes. The days are now over when the biological, psychological and the social need to be pitted against each other. Rather, they now have to be seen as mutually constituted. The brain is a social organ, embedded, embodied, enactive and extended,
in large part a reflection of the social conditions in which it grows.
Étudier l’expérience vécue de la victimation environnementale. L’apport de la green-cultural criminology
Authors: Natali Lorenzo
Published: December 2019

L’article explore les processus de victimation environnementale du point de vue d’une criminologie « verte » et « culturelle » ( green-cultural criminology ). Il défend l’adoption d’une approche visuelle dans l’enquête qualitative, au moyen d’une méthode connue sous le nom de photo-interprétation ( photo-elicitation ). Pour ce faire, il s’appuie sur des éléments généraux ainsi que sur une étude de cas menée à Huelva, dans le sud de l’Espagne, une ville gravement polluée par la présence voisine d’usines chimiques implantées dans les années 1960. Cette contribution souligne l’importance de mener des enquêtes empiriques sur la perception sociale des dommages environnementaux qui soient particulièrement attentives aux expériences et récits des acteurs eux-mêmes, avec ce que cela suppose de contradictions et de désaccords, voire de conflits.
La croix dans le langage du droit : retour sur la théorie de la rançon
Authors: Rouvière Frédéric
Published: December 2019

La théorie selon laquelle Jésus s’est donné en rançon au satan est jugée obsolète. On lui préfère généralement la théorie de la satisfaction ou de la substitution pénale qui pose que Jésus a pris le châtiment divin à notre place. Ces théories reposent sur une intuition fondamentale selon laquelle la croix et le droit sont en étroite relation. Abordant la question du point de vue spécifique des catégories du droit, Frédéric Rouvière souhaite montrer que l’interprétation juridique de la rançon est non seulement possible mais encore qu’elle est juridiquement mieux fondée que celle de la satisfaction ou substitution pénale. Le but n’est pas d’affirmer sa suprématie sur toutes les autres formes d’interprétation mais sur celles qui se réclament des catégories du droit. Grâce à l’herméneutique juridique, l’objectif final est de renouveler la réflexion sur la théorie de la rançon et de montrer qu’elle mérite mieux que le relatif mépris dans lequel elle est aujourd’hui confinée.
Adult Learning Styles and Attitudes Toward Computer Assisted Instruction
Authors: Brudenell Ingrid , Carpenter Connie Stewart
Published: December 2019

ABSTRACT

The purpose of this study was to determine if there was a relationship between learning style categories and attitudes toward computer assisted instruction (CAI). Few studies have attempted to compare adult learning style and attitude toward CAI.

In a one group pre- and post-test design, two questionnaires were administered to adult students enrolled in a nursing research course, which integrated CAI as an instructional method. The Attitude Toward Computer Assisted Instruction Semantic Differential Tbol (Alien, 1986) was completed twice. The Learning Style Inventory (Kolb, 1976), a self-report questionnaire to determine learning style, was completed once.

Data analysis indicated a significantly greater negative attitude toward CAI post-test. Subjects in all four learning style categories had statistically significantly greater negative attitudes on the function subscale, with assimilators also having a significantly greater negative attitude on the creativity subscale, as well as in overall attitude. The increasingly negative attitude toward CAI in this study may reflect several factors: an evaluation of the CAI software, and subject expectations of the CAI that were not met.
Can We Immunize Children Against Violence?
Authors: McGuiness Teena M.
Published: December 2019

EXCERPT Late one Friday night while I was volunteering at the battered women’s shelter, I heard one woman say, “He beats the crap out of me, but he never lays a hand on the children.” I began to think about the effects on a child of recurring family violence. Surely, witnessing violence must be detrimental to children’s self-esteem and behavior. We can immunize children against infectious diseases; is there anything that can be done to immunize them against becoming violent themselves?
