Published: October 2018

The molar mass (MM) and polydispersity indices (PDI) of acetylated hardwood kraft lignin (Ac-HWKL) and Ac-HWKL fractions were measured by size-exclusion chromatography with multi-angle laser light scattering (SEC-MALLS). The detectors worked at LL658 nm and LL785 nm. The MM of Ac-HWKL measured at 785 nm was much smaller than that measured at 658 nm. The number-average (Mn) and weight-average (Mw) molar masses of Ac-HWKL determined at 785 nm were approximately 6.2 and 6.5 times larger, respectively, than the values estimated using a conventional calibration curve created with authentic polystyrene standards in tetrahydrofuran (THF). Based on the Mw of Ac-HWKL fractions, the Mark-Houwink-Sakurada equation for Ac-HWKL was established to be [η]/ml g−1=0.320 M0.24 in THF and [η]/ml g−1=0.142 M0.26 in dimethyl sulfoxide (DMSO). These results demonstrate that Ac-HWKL has a more compact structure in an organic solvent than polystyrene.

Published: October 2018

Running biomechanics and its evolution that occurs over intensive trials are widely studied, but few studies have focused on the reproducibility of stride evolution in these runs. The purpose of this investigation was to assess the reproducibility of changes in eight biomechanical variables during exhaustive runs, using three-dimensional analysis. Ten male athletes (age: 23 ± 4 years; maximal oxygen uptake: 57.5 ± 4.4 ml02·min-1·kg-1; maximal aerobic speed: 19.3 ± 0.8 km·h-1) performed a maximal treadmill test. Between 3 to 10 days later, they started a series of three time-to-exhaustion trials at 90% of the individual maximal aerobic speed, seven days apart. During these trials eight biomechanical variables were recorded over a 20-s period every 4 min until exhaustion. The evolution of a variable over a trial was represented as the slope of the linear regression of these variables over time. Reproducibility was assessed with intraclass correlation coefficients and variability was quantified as standard error of measurement. Changes in five variables (swing duration, stride frequency, step length, centre of gravity vertical and lateral amplitude) showed moderate to good reproducibility (0.48 ≤ ICC ≤ 0.72), while changes in stance duration, reactivity and foot orientation showed poor reproducibility (-0.71 ≤ ICC ≤ 0.04). Fatigue-induced changes in stride biomechanics do not follow a reproducible course across the board; however, several variables do show satisfactory stability: swing duration, stride frequency, step length and centre of gravity shift.

Published: October 2018

The aim of this study was to examine the sequences of the first two goals scored in soccer matches in accordance with a range of different match contexts. Data from 1506 matches played in the Portuguese Premier League during six consecutive competitive seasons (2009-10 to 2014-2015) were analysed using descriptive statistics and the chi-square test in order to verify the association between variables and a Cox regression analysis was used to predict the time the second goal was scored in function of the time of the first goal scored in the match and the scoreline. The results revealed a higher frequency of the second goals being scored in the second half of a match (58%) and in the last 5 min periods of each half. A positive association was found for home teams and score-doubling goals (58%), as well as for away teams and score-equalizing goals (56%). For home and away teams the score-doubling goal of a match was strongly and positively associated with a win outcome for home (93%) and away teams (92%), while the score-equalizing goals were associated with a draw (home and away teams: 44%) and loss outcome (home: 33% and away teams: 32%). Finally, the Cox model showed that if the first goal was scored in the second half of the match, the probability of the second goal being scored was three times higher compared to the first half.

Authors: Bellar David , Etheredge Cory , Judge Lawrence W.
Published: October 2018

Suspension exercise systems are being used in strength and conditioning facilities, fitness centers, rehabilitation centers and home gyms. Though some evidence exists regarding the impact of training with these systems, more work is needed for a better understanding. The purpose of the present investigation was to examine the acute effects of an exercise session with 2 (hands only) and 4 straps (hands and feet) in the push-up exercise compared to a work-matched bench press exercise session. The participants for this repeated measures, cross-over investigation were 18 healthy college-aged males (age: 24.8 ± 3.5 yrs, body mass: 81.8 ± 7.8 kg, body height: 178.9 ± 4.5 cm). The conditions were 6 sets of 10 repetitions of suspension push-ups using two straps (DUAL) for the hands, fours straps (QUAD) for hands and feet and a traditional bench press exercise matched to the average resistance during the suspension push-up. The participants performed all repetitions at a controlled cadence. Expired gases, and heart rate were monitored continuously during the exercise session. Pre and post exercise saliva samples were collected to quantify changes in testosterone and cortisol. Upper body isometric strength tests ( UBIST) were performed (Post, 1 hr, 24 hr, 48 hr) to evaluate changes in force production during recovery. Data analysis via repeated measures ANOVA revealed a significant trend for increased oxygen consumption in the QUAD condition compared to the bench press (p = 0.019). Additionally, both suspension conditions resulted in a reduced respiratory exchange ratio as compared to the bench press (p < 0.05). A significant main effect was noted for time in all conditions regarding isometric strength (p < 0.001), but no differences between conditions were revealed. Testosterone and cortisol responses did not differ between conditions. Based upon these data, it appears that when matched for work, suspension exercise results in equivalent reductions in muscle force, but greater oxygen consumption compared to isotonic exercise.

Authors: Rumaisa N. , Hanim M. R. Norazatul , Hii C. L.
Published: October 2018

The effects of drying temperature (120 °C to 200 °C) on drying characteristics of black tea leaves using superheated steam dryer (SHS) were investigated. It was observed that increased drying temperature caused higher drying rate that helped to shorten drying times. The effective diffusivities of moisture transfer in SHS ranged between 2.30 × 10–10 and 3.90 × 10–10 m2/s within the temperature range tested. The effective diffusivities were correlated by Arrhenius relationship with Arrhenius constant and activation energy estimated at 1.07 × 10–8 m2/s and activation energy 12.34 kJ/mol, respectively. Increased in drying temperature and time significantly decreased the brightness (*L) of tea leaves from 26.34 to 22.66 and TPC from 87.93 to 42.39 mg/g. However, comparison to commercial black tea showed that SHS dried-tea leaves exhibited better colour attribute and 91.4% higher in phenolic content.
Basal characteristics and first year responses to human growth hormone (GH) vary according to diagnostic criteria in children with non-acquired GH deficiency (naGHD): observations from a single center over a period of five decades
Authors: Ranke Michael B. , Schweizer Roland , Binder Gerhard
Published: October 2018

Background

Children with non-acquired (na) growth hormone deficiency (GHD) diagnosed over decades in one center may provide perspective insight.

Methods

naGHD is divided into idiopathic GHD (IGHD), GHD of known cause (cGHD) and GHD neurosecretory dysfunction (NSD); time periods: <1988 (I); 1988–1997 (II); 1998–2007 (III); 2008–2015 (IV). Descriptive analyses were performed at diagnosis and during first year GH treatment.

Results

Patients (periods, N): I, 87; II, 141; III, 356; IV, 51. In cGHD (all), age, maximum GH, insulin-like growth factor-I (IGF-I), and insulin-like growth factor-binding protein-3 (IGFBP-3) (5.1 years, 3.6 μg/L, −5.3 standard deviation score [SDS], −3.7 SDS) were lower than in IGHD (all) (6.8 years 5.8 μg/L, −2.5 SDS, −1.0 SDS), but not height (−3.1 vs. −3.2 SDS). Characteristics of NSD were similar to that of IGHD. Patients with IGHD – not cGHD – diagnosed during 2008–2015 (IV) were the youngest with most severe GHD (maxGH, IGF-I, IGFBP-3), and first year height velocity (HV) and ∆ IGF-I (10.5 cm/year, 4.0 SDS) but not ∆ height SDS were the highest on recombinant human growth hormone (rhGH) (27 μg/kg/day).

Conclusions

Although during 1988–2007 patient characteristics were similar, the recently (>2008) stipulated more stringent diagnostic criteria – HV before testing, sex steroid priming, lower GH cut-off – have restricted diagnoses to more severe cases as they were observed before the rhGH era.

Authors: Sabutsch Stefan , Weigl Gerhard
Published: October 2018

With the implementation of the Austrian electronic health record (ELGA), laboratory results are formally standardized for the first time throughout Austria. The nomenclature of the lab analyses, their sequence and structure as well as the display of laboratory results are unified with ELGA. One of the most significant steps is using Logical Observation Identifiers Names and Codes (LOINC) as a reference terminology for lab analyses. Thereby laboratory results can be reused semantically interoperable all over Austria.

Social Media Marketing – from Tool to Capability
Authors: Venciūtė Dominyka
Published: October 2018

Whereas the application of social media marketing has been trending in business, the theoretical research that analyses the phenomenon of social media marketing is to some extent lagging behind. In practice, social media marketing is often viewed as a customer relationship management (CRM) tool or technique and not as a capability. This paper builds on the theories of the resourced-based view (RBV) and dynamic capabilities to explore the concept of social media marketing capability. The aim of this paper is to redefine the phenomenon of social media marketing capability and to contribute to the existing literature. In addition, it urges firms to look into social media marketing not only as a tool or technique, but also as an organizational capability.
Sparse Signal Acquisition via Compressed Sensing and Principal Component Analysis
Authors: Andráš Imrich , Dolinský Pavol , Michaeli Linus , Šaliga Ján
Published: October 2018

This paper presents a way of acquiring a sparse signal by taking only a limited number of samples; sampling and compression are performed in one step by the analog to information conversion. The signal is recovered with minimal information loss from the reduced data record via compressed sensing reconstruction. Several methods of analog to information conversion are described with focus on numerical complexity and implementation in existing embedded devices. Two novel analog to information conversion methods are proposed, distinctive by their computational simplicity - direct subsampling and subsampling with integration. Proposed sensing methods are intended for and evaluated with real water parameter signals measured by a wireless sensor network. Compressed sensing proves to reduce the data transfer rate by >80 % with very little signal processing performed at the sensing side and no appreciable distortion of the reconstructed signal.
A Novel Dynamic Method to Improve First-order Natural Frequency for Test Device
Authors: Zhang Jun , Tian Yu , Ren Zongjin , Shao Jun , Jia Zhenyuan
Published: October 2018

It is important to improve the natural frequency of test device to improve measurement accuracy. First-order frequency is basic frequency of dynamic model, which generally is the highest vibration energy of natural frequency. Taking vector force test device (VFTD) as example, a novel dynamic design method for improving first-order natural frequency by increasing structure stiffness is proposed. In terms of six degree-of-freedom (DOF) of VFTD, dynamic model of VFTD is built through the Lagrange dynamic equation to obtain theoretical natural frequency and mode shapes. Experimental natural frequency obtained by the hammering method is compared with theoretical results to prove rationality of the Lagrange method. In order to improve the stiffness of VFTD, increase natural frequency and meet the requirement of high frequency test, by using the trial and error method combined with curve fitting (TECF), stiffness interval of meeting natural frequency requirement is obtained. Stiffness of VFTD is improved by adopting multiple supports based on the stiffness interval. Improved experimental natural frequency is obtained with the hammering method to show rationality of the dynamic design method. This method can be used in improvement of first-order natural frequency in test structure.

Authors: Wang Xuewei , Wang Jing
Published: October 2018

With the rapid construction of smart grid, many applications of the new generation and the large power dynamic loads are revolutionizing the electrical energy measurement of electricity meters. The dynamic measurement errors produced by electricity meters are intolerable. In order to solve the dynamic error measurement of electrical energy, firstly, this paper proposes a three-phase pseudorandom dynamic test power signal model to reflect the main characteristics of dynamic loads. Secondly, a compressive measurement algorithm is proposed by the means of steady-state optimization to accurately measure the electrical energy. The experimental results confirm the effectiveness of the three-phase pseudorandom dynamic test signal model, the maximum errors of compressive measurement algorithm are superior to 1×10-13, the high precision enables the algorithm to accurately measure the electrical energy under different dynamic conditions.
Isolation, Identification and Preservation of Fusarium Spp. Causing Dry Rot of Potato Tubers
Authors: Stefańczyk Emil , Sobkowiak Sylwester
Published: October 2018

Fungi of the genus Fusarium cause dry rot, a potato disease which develops during long-term storage of tubers. The disease-inducing capabilities differ among Fusarium spp., but may also vary within species universally considered main dry rot agents. Identification of Fusarium spp. present on diseased tubers in a surveyed area can help minimize crop losses and mycotoxin contamination by, for example, applying proper fungicides or planning crop rotation. Here, we present a procedure of obtaining single spore colonies of Fusarium spp. from potato tubers infected by dry rot, their identification using molecular methods and ways of preservation.
Cryopreservation of Shoot Tips and Pollen of Potato
Authors: Smyda-Dajmund Paulina
Published: October 2018

Cryopreservation is a frequently used method of long-term storage of potato meristems and pollen in liquid nitrogen (LN) in temperature of -196°C. This technique allows for theoretically unlimited storage of potato material. The most popular method of potato shoot tips preservation is cryopreservation by the solidification of liquids without crystallization (vitrification).The best method of pollen conservation is its direct immersion in LN. The successful regeneration after vitrification is genotype-dependent, which require optimization of protocol.
The role of vowel parameters in defining lexical and subsidiary stress in Ukrainian
Authors: Łukaszewicz Beata , Mołczanow Janina
Published: October 2018

Recent work suggests that Ukrainian represents a typologically rare bidirectional stress system with internal lapses, i.e. sequences of unstressed syllables in the vicinity of primary stress (Łukaszewicz and Mołczanow 2018a, b). The system is more intricate than the hitherto known bidirectional systems (e.g. Polish), and thus interesting from the theoretical perspective, as it involves interaction between free lexical stress and secondary stresses. Lexical and subsidiary prominence in Ukrainian have been shown to be expressed acoustically in terms of increased duration of the whole syllable. This leaves open the question of the role of classic vowel parameters in shaping prominence effects in this language. The present study fills this gap by investigating vowel duration, intensity, and F0 as potential acoustic correlates of primary and secondary stress in Ukrainian. It focuses on words with primary stress on the fifth syllable. Such words are predicted to have secondary stress on the first and third syllables. The results point to statistically significant lengthening of vowels carrying lexical stress as well as of those in the initial syllable, but not in the third syllable. A possible explanation is that other parameters, e.g. consonant duration, may be crucial in the case of word-internal subsidiary stress in Ukrainian.
Croatian occupational terminology: The 2000s’ escape from “A Man’s World”
Authors: Hrga Anđela Milinović
Published: October 2018

This paper is concerned with the forms of expression of occupational terms in contemporary Croatian institutional practice, typical of the changes in language policy and public language usage. Predominant in Croatian language was the androcentric practice of using masculine occupational terms as unmarked, gender-neutral. However, due to various reasons, it has changed in past years. The 2008 Amendments to the Croatian National Classification of Occupations marked the turning point in gender equality in terms of providing for gender-specific occupational nouns. For the first time, an official document codified both masculine and feminine occupational titles and stipulated their usage as a national classification standard, thus acknowledging a significant language change. However, the 2008 and 2010 Classifications both displayed certain asymmetries as well. The paper pinpoints these asymmetries, documents elements of linguistic sexism still remaining, as well as successful “escapes” from it, and tries to determine whether imbalances and barriers within the binary masculine-feminine concept are brought about by intralinguistic (lexical) or extralinguistic factors.

Cavina E., Bucchi R. and Busse P. 2018. The general pattern of seasonal dynamics of the autumn migration of the Wood Pigeon Columba palumbus in Italy. Ring 40: 3-18.

Given the scarcity of studies on the migration of the Wood Pigeon through Italy, the first systematic observations by a network of hunters, as citizen researchers, can be presented as a starting point for more in-depth analyses. Observations from the years 1998-2006 are analysed and presented in a generalized form. During this period more than 100 observation sites, covering most of Italy, were active for about 40 days every autumn. Migration over Italy was described in terms of the timing and intensity of migration. Special attention was directed to the long-term number dynamics and seasonal dynamics of the passage. The most intensive migration was observed within northern Italy, while lower intensity is visible more to the south of the peninsula. Following tendencies in numbers of observed migrants within the ten years of the study, we can find positive tendencies in most of the northern provinces, while three negative trends are visible in central Italy. The study of the seasonal pattern, in terms of the number dynamics of the passage and the frequency of pronounced peak days, strongly suggests that there are five or six waves of pigeons passing through Italy in different parts of the autumn that are quite stable between years. Every year the time of the passage includes a few peak days of migration.
Intonazione e significato: l’esempio dell’italiano regionale di Bergamo
Authors: Antonioli Giorgio , Moroni Manuela Caterina
Published: October 2018

In this paper we present a selection of preliminary results of our research project “Intonation and Meaning”, in which we compare recurrent intonation contours in German and Italian regional varieties. We apply the method of German Interactional Prosody Research (Interaktionale Prosodieforschung), which in turn is based on Conversation Analysis, to a sample of selfcollected empirical data. Our aim is to show the value of intonation as a resource to contextualize speech activities and to point out form-function relationships between intonation patterns and speech act types. In this respect, we observe the usage of intonation contours with rising accent (L*H) and with falling accent (H*L) in the utterance of question activities, and provide evidence for the fact that the latter represent a distinctive type of questions with epistemic presupposition, whereas L*H correlates rather with default, modally unmarked questions.
Sprache, Grammatik, Variation – viticulture linguistique
Authors: Stark Elisabeth
Published: October 2018

The aim of this contribution is to reposition a key notion to the centre of Wulf Oesterreicher’s theoretical disciplinary reasoning: grammar, or more generally, ‘rules and norms’ specific to single languages and varieties the linguist deals with. This includes contingent, non-motivated structures, and claiming the necessity to analyse their existence ‘as such’ (i.e., also independently of communicative, social etc. factors) as the core task of linguistics. This point is illustrated with a much debated variable in French descriptive linguistics: past participle agreement. Combining theoretical and corpus linguistic observations, the distribution of the two variants (absence vs. realization of agreement) in constructions with the auxiliary avoir shows that a grammatical analysis interested in the derivation of certain rules and their application in actual language usage permits to understand the logic of linguistic variation - at least the one observable alongside the standard - non-standard opposition in French.
Der kompetente Sünder. Zur auktorialen Selbstdarstellung Francesco Petrarcas in De otio religioso
Authors: Huss Bernhard
Published: October 2018

Francis Petrarch has developed many diverse strategies to present himself as an author. When constructing his own figura auctoris, he refers to a highly stylized version of his autobiographical ego to which he ascribes a particular epistemic competence. Indeed, such competence serves as the basis of both authority and authorship. In his De otio religioso, Petrarch addresses the community of the Carthusian monks of the Abbey of Montrieux in Southern France. Paradoxically, he introduces himself to them as being competent with regard to questions of monastic life, although in this respect his addressees should be much more competent than Petrarch can be. At the same time the author depicts himself as a great sinner. As such, he cannot dispose of considerable knowledge in religious matters. Instead, he points out his extraordinary cultural expertise as a philologist, humanist and owner of books, a knowledge that makes him, the sinner, become an author able to instruct the monks. Petrarch negotiates the claims to validity asserted by two different cultures (Christian vs. pagan, late antique/medieval vs. antique/early-modern) and seeks to position himself as an author with authority in both fields.
César Hautot – ein naturalistischer Ödipus? Guy de Maupassants Hautot père et fils auf der Schwelle zur Psychoanalyse
Authors: Jacobi Claudia
Published: October 2018

Literary criticism has mentioned some affinities between Guy de Maupassant’s literary work and Freud’s psychoanalysis, without ever reflecting on Maupassant’s literary anticipation of the Oedipus complex. The latter is particularly evident in the short novel Hautot père et fils (1889), which has not received much attention to date. The article aims to illustrate some evident parallels between Maupassant’s literary representation of a father-son conflict and Freud’s scientific approach. In doing so, it does not intend to deliver a demonstration of the emergence of Freudian concepts from naturalistic fiction. It shall rather be considered as a literary case study, which illustrates the discourse-historical process of transformation from the physiological paradigm of naturalism to the psychological paradigm of the arising psychoanalysis.

The investigation was aimed to evaluate the effects of 3-weeks swimming exercise on blood pressure and redox status in high-salt-induced hypertensive rats. Male Wistar albino rats (n=40, 6 weeks old) were divided into 4 groups: 1. hypertensive rats that swam for 3 weeks; 2. sedentary hypertensive control rats; 3. normotensive rats that swam for 3 weeks; 4. sedentary normotensive control rats. Hypertensive animals were on high concentrated sodium (8% NaCl) solution for 4 weeks (period of induction of hypertension). After sacrificing, hearts were isolated and perfused according to Langendorff technique at gradually increased coronary per-fusion pressure from 40–120 cmH2O. The oxidative stress markers were determined in coronary venous effluent: the index of lipid peroxidation (measured as TBARS), nitrites (NO2
−), superoxide anion radical (O2
−) and hydrogen peroxide (H2O2). Swimming did not lead to significant changes in levels of TBARS, NO2
−, O2
− in any of compared groups while levels of H2O2 were significantly higher in swimming hyper-tensive group comparing to swimming normotensive group at coronary perfusion pressure of 80–120 cmH2O. Our results indicate that the short-term swimming start to reduce blood pressure. In addition it seems that this type of swimming duration does not promote cardiac oxidative stress damages.

Authors: Oztopuz Ozlem , Sarigul Nermin , Liaqat Fakhra , Park Ro-Dong , Eltem Rengin
Published: October 2018

Background

Biological control of pathogenic fungi is a possible alternate to the chemical control, which is harmful to humans and environment. Soil-borne Bacillus strains can be potential biocontrol agents and a source of lytic enzymes.

Aim

This study aimed to examine biocontrol potential and lytic enzyme activities of a soil isolate Bacillus subtilis Ege-B-1.19.

Materials and methods

Strain was identified by biochemical and 16S rRNA gene analysis and its biocontrol activity was investigated against Aspergillus niger EGE-K-213, Aspergillus foetidus EGE-K-211, Aspergillus ochraceus EGE-K-217, Fusarium solani KCTC6328, Rhizoctonia solani KACC40111 and Colletotrichum gloeosporioides KACC40689. Chitinase, chitosanase, N-acetyl-β-hexosaminidase and protease activities of B. subtilis Ege-B-1.19 were also determined. Chitosanase was purified using Sephadex G-150 column and its molecular weight was determined by SDS-PAGE. Chitooligosaccharides production using chitosanase was carried out and analysed by TLC and HPLC.

Results

Results depicted that B. subtilis Ege-B-1.19 has shown inhibitory effects against all the test fungi. Chitinase, chitosanase, N-acetyl-β-hexosaminidase and protease activities were determined as 2.7 U mL−1, 7.2 U mL−1, 6.2 U mL−1 and 12.2 U mL−1, respectively. Molecular weight of purified chitosanase was 44 kDa. Chitosanase hydrolysed chitosan to glucosamine (GlcN), dimers (GlcN)2 and trimers (GlcN)3.

Conclusion

Bacillus subtilis Ege-B-1.19 can be anticipated as useful biocontrol agent and its chitosanase can be utilized for enzymatic synthesis of chitooligosaccharides.
Friedrich Max Müller und die idealistische Wurzel der Religionswissenschaft
Authors: Zolotukhin Vsevolod V.
Published: October 2018

Dieser Beitrag widmet sich dem Zusammenhang zwischen dem deutschen Idealismus und Max Müllers Religionswissenschaft, die als erstes und maßgebendes religionswissenschaftliches Projekt betrachtet werden kann. Es wird aufgezeigt, dass die Entwicklung der Lehre Müllers erst durch Kants Kritizismus (besonders die Kritik der natürlichen Theologie und die Lehre vom Erhabenen), Schleiermachers Gefühlsphilosophie (besonders die Unterscheidung zwischen Religion und Theologie) und durch die idealistische Religionsphilosophie von F. Schelling und Chr. Weisse (die Religionstheorie als besonderer Zweig der Wissenschaft) ermöglicht wurde. Es kann auch der Einfluss der Philosophie von J. Fries aufgespürt werden. Müllers Blick auf das religiöse Leben der Menschheit hat einen philosophischen Charakter und wird wesentlich durch die Methodologie des deutschen Idealismus geprägt. Es gibt dennoch zwei Hauptunterschiede zwischen Müllers Religionswissenschaft und der früheren Religionsphilosophie. Zum einen benutzt Müller systematisch Originalquellen in östlichen Sprachen. Zum anderen geht Müller dadurch über die europäische Denktradition hinaus und versucht, in nichteuropäische Traditionen einzudringen und diese zu verstehen. Der deutsche Idealismus eben ermöglicht einen solchen bedeutenden Zug der Religionswissenschaft wie die Anerkennung der Diskrepanz zwischen dem, was in einem Gespräch über die Religion gesagt wird, und dem persönlichen Verhältnis des Gelehrten dazu.

Published: October 2018

We examined adherence, medication-taking practices, and preferences to inform development of a wrist-worn adherence system. Two convenience samples of persons taking antiretroviral therapy and HIV pre-exposure prophylaxis completed a survey. Additional online questions asked about willingness to use a wrist-worn device and reminder and feedback preferences. Among 225 participants, 13% reported adherence < 90% this was associated with younger age and clinic sample. Compared to pill bottle–using participants, mediset users less commonly reported adherence < 90% (aOR = 0.16, p = .02), and blister pack users (aOR = 6.3, p = .02) and pill roll users (aOR = 3.3, p = .04) more commonly reported adherence < 90%. Sixty-two percent of the online participants reporting adherence (< 100%) had some interest in receiving adherence reminders, including 42% with interest in receiving reminders by smartwatch notifications. Although confounders are likely, formative work identified potential users and interest in using a wrist-worn adherence system. Future work will determine its acceptability and efficacy.
Pensar la construcción de paces en Colombia: la (ir)relevancia teórico-práctica de la decolonialidad

Published: October 2018

En el presente artículo reflexivo se describe y analiza el tránsito de la Modernidad del siglo XIX a la Postmodernidad actual. En las sociedades avanzadas occidentales surgen conflictos sociales y culturales por la complejidad, fragmentación y pérdida de referentes sociales. Estos elementos están en toda la estructura social, también en la escuela y la familia. Estas dos instituciones están en crisis por no dar respuestas satisfactorias a los retos planteados. Los menores son el colectivo más perjudicado por la descomposición social y el relativismo imperante. Estos no reciben la capacitación y orientación adecuadas para instalarse e integrarse en sociedades violentas, complejas, difusas y contradictorias.
¿Tú quieres más? La Economía del deseo
Authors: Segura Gutiérrez José Miguel
Published: October 2018

El artículo defiende el carácter productivo que presenta el deseo como factor de constitución subjetiva en el sujeto posmoderno. Para ello, parte de una revisión bibliográfica al concepto de “deseo”, entendido aquí como potencia transformadora del individuo y su realidad, dentro de una espacio temporalidad marcada predominantemente por el capital y carácter utilitaristas de las relaciones sociales. Cuestión, que mina la posibilidad de construir sentido social-solidario y más por el contrario, refuerza la constitución de un sujeto egoísta, cuyo cambio ha sido agenciado por un cúmulo de situaciones, que dada su apariencia terminan distanciándolo o haciéndolo negar su naturaleza gregaria, dentro de diversos flujos existenciales y modos de vida cuya base descansa en la optimización corporal, como mecanismo clave en el logro del éxito personal y por extensión del reconocimiento social al mismo.
Transcriptomic Plasticity in the Arthropod Generalist Tetranychus urticae Upon Long-Term Acclimation to Different Host Plants

The two-spotted spider mite Tetranychus urticae is an important pest with an exceptionally broad host plant range. This generalist rapidly acclimatizes and adapts to a new host, hereby overcoming nutritional challenges and a novel pallet of constitutive and induced plant defenses. Although recent studies reveal that a broad transcriptomic response upon host plant transfer is associated with a generalist life style in arthropod herbivores, it remains uncertain to what extent these transcriptional changes are general stress responses or host-specific. In the present study, we analyzed and compared the transcriptomic changes that occur in a single T. urticae population upon long-term transfer from Phaseolus vulgaris to a similar, but chemically defended, host (cyanogenic Phaseolus lunatus) and to multiple economically important crops (Glycine max, Gossypium hirsutum, Solanum lycopersicum and Zea mays). These long-term host plant transfers were associated with distinct transcriptomic responses with only a limited overlap in both specificity and directionality, suggestive of a fine-tuned transcriptional plasticity. Nonetheless, analysis at the gene family level uncovered overlapping functional processes, recruiting genes from both well-known and newly discovered detoxification families. Of note, our analyses highlighted a possible detoxification role for Tetranychus-specific short-chain dehydrogenases and single PLAT domain proteins, and manual genome annotation showed that both families are expanded in T. urticae. Our results shed new light on the molecular mechanisms underlying the remarkable adaptive potential for host plant use of generalist arthropods and set the stage for functional validation of important players in T. urticae detoxification of plant secondary metabolites.
A Comprehensive Spectral Analysis of the Auto-fluorescence Characteristics of Three Algae Species at Twelve Discrete Excitation Wavelengths
Authors: Deglint Jason L. , Jin Chao , Wong Alexander
Published: October 2018

Harmful algae blooms are a growing concern around the globe, and therefore fast and reliable methods to detect and classify different types of algae in an automatic manner is highly desired. In this study, we explore the auto-fluorescence characteristics of different algae types to determine whether using their auto-fluorescence spectra could be used in automatic identification. Preliminary experimental results in this study for generating auto-fluorescence spectra ofÂ Anabaena flos-aquaeÂ (Cyanophyta phylum),Â Ankistrodesmus falcatusÂ (Chlorophyta phylum), andÂ Euglena gracilisÂ (Euglenozoa phylum) demonstrate that this information could potentially be leveraged to discriminate between different types of algae. Future work must be done to explore the auto-fluorescence spectra of additional species within a given genus in order to determine the intra-class and inter-class variability of these auto-fluorescence spectra. Future work also includes using this technique to determine the concentration in a mixed sample, as well as determining the robustness in a sample with contaminants. Future work will also involve exploring the use of additional fluorescent images, absorption spectra, and morphological features to improve the performance of the classifiers. Finally, as data collection continues we will explore using data augmentation to deal with unbalanced class sizes.

Authors: Sandoval Carmenza Liliana , Acosta Bernarda Jinneth , Contreras Oscar , Vargas Jorge
Published: October 2018

Introducción. La amiloidosis sistémica primaria hace parte del espectro de neoplasias de células plasmáticas, donde las cadenas livianas de inmunoglobulina se depositan en múltiples órganos. El compromiso miopático con falla respiratoria y mieloma múltiple asociado es poco frecuente. Caso clínico. Se presenta el caso de un paciente con amiloidosis sistémica de cadenas livianas (AL) quien ingresó por miopatía con falla respiratoria e íleo adinámico, por lo que se llevó a la unidad de cuidados intensivos. Por histología se confirmó infiltración en piel y tracto digestivo y concomitantemente se presentó mieloma múltiple con lesiones óseas líticas y riñón de mieloma. El paciente tuvo buena respuesta al esquema CyBorD (ciclofosfamida, bortezomib, dexametasona), recuperó su función renal y tuvo disminución de las lesiones en piel. Sin embargo, el compromiso gastrointestinal y miopático fue difícil de manejar y se requirió soporte ventilatorio y nutrición parenteral. Discusión. El clínico puede pasar por alto esta patología, por lo que es probable llegar a fases avanzadas de la enfermedad. En la actualidad, con nuevos agentes de quimioterapia y trasplante autólogo, se puede aumentar la sobrevida de estos pacientes. Conclusión. La amiloidosis AL tiene un amplio espectro de manifestaciones y debe considerarse en los diagnósticos diferenciales a fin de hacer un diagnóstico precoz y hacerla una condición tratable.
Herlyn-Werner-Wünderlinch syndrome: case report
Authors: Figueroa-Blanco Andrés Felipe , Montañez-Aldana Miguel Ángel
Published: October 2018

Introducción. El síndrome de Herlyn-Werner-Wünderlich (HWW) es una asociación de tres alteraciones anatómicas urogenitales de baja incidencia. Las alteraciones müllerianas son poco comunes y suelen ser hallazgos incidentales, por lo que se encuentran subdiagnosticadas y poco se conoce su génesis o su relación con tener más probabilidad de expresión en el lado derecho. Reporte de caso. Se trata de una paciente de 17 años quien consultó por dolor abdominal hipogástrico de fuerte intensidad ligado a sangrado fétido. En el examen físico se encontró tabique vaginal y en las imágenes complementarias se evidenció útero didelfo y agenesia renal, diagnosticando así síndrome HWW. Igualmente, se documentó piómetra y hematocolpos que se manejaron con terapia de antibióticos; dada la adecuada respuesta al tratamiento, se dio egreso hospitalario con seguimiento por consulta externa, pues el manejo definitivo no se pudo proporcionar durante la estancia hospitalaria. Discusión. Una causa de abortos a repetición es la presencia de síndrome HWW; sin embargo, al ser correctamente diagnosticado, se puede dar un tratamiento definitivo que disminuya las perdidas concepcionales y colecciones hematopurulentas urogenitales. Conclusiones. El síndrome HWW es una malformación poco común que aumenta el riesgo de padecer cuadros infecciosos ginecológicos o colecciones hemáticas. El tratamiento definitivo consiste en el manejo quirúrgico del tabique vaginal que mejora la calidad de vida y disminuye el riesgo de morbilidades asociadas a la patología.
Do Conto ao Seriado: Duas Histórias
Authors: Dugnani Patricio
Published: October 2018

Pretende-se, nessa pesquisa, analisar a estrutura narrativa dos seriados contemporâneos, com a estrutura narrativa do conto, para verificar se essas duas formas de expressão apresentam estruturas comuns, e se existe uma influência da estrutura narrativa do conto literário, nos seriados televisivos contemporâneos. Parte-se da hipótese de que o primeiro, influência o segundo. Para realizar essa comparação serão utilizadas, principalmente, as análises e conceitos das estruturas narrativas da TV e dos seriados de Arlindo Machado, e de Marshall Mcluhan, os estudos sobre o conto de Ricardo Píglia e Nádia Gotlieb, o conceito de intertextualidade de Roland Barthes, e Leda Tenório da Motta.

Narrativas do outro: imagens e mediações complexas em “Fuocoammare”
Authors: Mendes Lobato José Augusto
Published: October 2018

Este trabalho busca lançar uma abordagem crítica sobre obras audiovisuais centradas na alteridade, tomando, como objeto de estudo, o documentário Fogo no Mar (Fuocoammare, Gianfranco Rosi, 2016), e sua representação das interações entre os moradores da ilha italiana de Lampedusa e os refugiados do Norte da África e do Oriente Médio. Para isso, autores dos estudos sobre imagem, cinema, mídia e cultura e das ciências da linguagem são usados para compreender a mediação do outro operada a partir do testemunho, da construção de polos opositivos e de um regime de imagens pautado pela sensorialidade e pelo realismo
Vaporwave: Dadaísmo digital de mídias
Authors: Mello Jamer Guterres de , Arruda Mario Alberto Pires de
Published: October 2018

Este artigo busca investigar as relações técnicas, discursivas e expressivas entre os movimentos estéticos Vaporwave e Dadaísmo. O primeiro é um movimento cuja expressão se dá na interseção entre música, vídeo e imagem estática a partir de material digital disponível na internet; o segundo foi um movimento das vanguardas artísticas modernas do início do século passado, formado principalmente na Europa por um grupo de escritores, poetas e artistas plásticos. Mais especificamente o objetivo deste texto é tentar identificar de que forma o tipo de apropriação efetuado no Vaporwave se assemelha às estratégias de criação utilizadas pelos dadaístas. O que evidenciamos nas investigações aqui propostas é que tanto o Dadaísmo quanto o Vaporwave funcionam como contra-ambientes (MCLUHAN; STAINES, 2005) que revelam as lógicas de funcionamento das mídias hegemônicas, produzindo novos hábitos e usos em relação às tecnologias.
A questão da autonomia do roteiro cinematográfico
Authors: Suppia Alfredo , Romanzoti Natasha
Published: October 2018

A teoria e prática do roteiro tem lugar de inequívoca relevância no ensino superior de cinema e audiovisual. Não obstante, no âmbito da pesquisa e reflexão teórica acerca das artes cinemáticas, especialmente em nível da pós-graduação, o roteiro costuma ser deslocado em importância pelo produto final, o filme. É possível constatar uma variedade de pesquisas que equalizam em importância o roteiro ao filme, ou que privilegiam o roteiro como objeto principal de estudo. Mesmo assim, no caso dos estudos contemporâneos de cinema, no Brasil, tais pesquisas ainda subsistem marginalmente. O objetivo deste artigo é investigar a autonomia do roteiro em estudos de cinema e audiovisual. Deve o roteiro ser tratado como um gênero literário? Pode o roteiro ser divorciado do filme?
Narrar as Ruínas: por uma hermenêutica do conflito
Authors: Do Amaral Diego Granja
Published: October 2018

Lançando mão da hermenêutica em Ricoeur (2010;2012), o presente artigo investiga a hipótese de que o território Palestino como corpo político (SAFATLE, 2015), encontra fundamento na dimensão simbólica da palavra narrada. Com apoio do método indiciário (GIZBURG, 1989), desejamos construir esta hipótese através do rastreamento de relatos que compõem uma espécie de narrativa polifônica sobre a questão Palestina. Entre os textos estão os poemas de Mahmoud Darwish, o romance memorialístico de Sahar Hamouda, reportagens de Joe Sacco e o game Undersiege. Como operador central, a narrativa, vetor capaz de catalisar o luto em potência política. À guisa de conclusão, defendemos que a identidade palestina se organiza a partir de um mosaico de vozes a partir do exílio da memória.
