Published: May 2017

Abstract

Background
Adolescent girls in Nigeria experience a disproportionately high burden of sexual and reproductive health disparities that affect their well-being. Yet, little is known about adolescent girls’ own unique perspectives of the sexual and reproductive health challenges they face, and possible solutions to these challenges.

Aims
To explore top sexual and reproductive health concerns of female adolescents in Nigeria and their perceptions regarding potential solutions to these issues.

Methods
Eighty adolescent girls attending two public secondary schools in Lagos, Nigeria completed individual free-listing interviews. Items assessed their perceptions of the most important sexual and reproductive health issues and potential solutions to these issues at the individual and societal level. Data were analyzed using Anthropac 4.98 to sort the lists by item frequency as well as to determine Smith’s salience index (S).

Results
The top five sexual and reproductive health concerns identified by participants were human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS), followed by menstrual pain, vaginal infections, sexual abuse and teenage pregnancy. Adolescent girls stated that youth empowerment programs that provide access to skills-building opportunities and mentors was one potential strategy for addressing their sexual and reproductive health priorities. Other solutions identified were access to medical checkups, general health talks focused on their sexual and reproductive health concerns as well as access to health facilities and opportunities to build self-efficacy skills.

Conclusion
Adolescent girls in Nigeria need to be engaged in becoming powerful agents in improving their own sexual and reproductive health, and in crafting solutions that may be effective in enabling them to achieve their full potential and rights to health and well-being. The findings will be used to develop an intervention targeting the sexual and reproductive health priorities of adolescent girls in Lagos, Nigeria.
CFD-DEM Numerical Simulation and Experimental Validation of Heat Transfer and Two-Component Flow in Fluidized Bed
Authors: Guo Feihong , Zhong Zhaoping 
Published: May 2017

Abstract
Based on the improved computational fluid dynamics and discrete element method (CFD-DEM), heat transfer and two-component flow of biomass and quartz sand have been studied from experiments and numerical simulation in this paper. During experiments, the particle temperature and moving images are respectively recorded by infrared thermal imager and high speed camera. With the increase of the velocity, the mixing index (MI) and the cooling rate of the particles are rising. Due to larger heat capacity and mass, the temperature of biomass drops slower than that of quartz sand. Fictitious element method is employed to solve the incompatibility of the traditional CFD-DEM where the cylindrical biomass are considered as an aggregation of numerous fictitious sphere particles arranged in certain sequence. By the comparison of data collected by infrared thermal imager and the simulated results, it can be concluded that experimental data is basically agreement with numerical simulation results. Directly affected by inflow air (25℃), the average temperature of particles in the bed height area (h >30 mm) is about 3 degrees lower than that of the other heights. When the superficial gas velocity is larger, the fluidization is good, and the gas temperature distribution is more uniform in the whole area. On the contrary, bubbles are not easy to produce and the fluidization is restricted at lower superficial gas velocity. Gas-solid heat transfer mainly exists under the bed height of 10 mm, and decreases rapidly on fluidized bed height. The mixing index (MI) is employed to quantitatively discuss the mixing effectiveness, which first rises accelerate, then rising speed decreases, finally tends to a upper limit.

Published: May 2017

Abstract
Tuna by-products were subjected to enzymatic hydrolysis with Alcalase (enzyme to substrate ratio 1 : 200 w/w; 60 °C; pH 6.5, 120 min) rendering a tuna protein hydrolysate (TPH) with 9.24 % degree of hydrolysis (DH). The antioxidant capacity of TPH determined by the methods of ferric reducing antioxidant power (FRAP) and Trolox equivalent antioxidant capacity (TEAC) were similar and 10 times lower than the result obtained by oxygen radical absorbance capacity (ORAC). The total amino acid profile indicated that 42.15 % are composed of hydrophobic amino acids and 7.7 % of aromatics, with leucine being found in the highest quantity (17.85 %). The fatty acid profile of the oil recovered by centrifugation of the TPH – as determined by a gas chromatograph – was characterized by a high percentage of polyunsaturated fatty acids (PUFAs) (39.06 %), mainly represented by the fatty acids ω3, docosahexaenoic acid (27.15 %) and eicosapentaenoic acid (6.05 %). The simultaneous recovery of unsaturated fatty acids and antioxidant peptides can add value to tuna by-products, assisting in the efficient management of fishing industry waste.
Evaluation of Mass Transfer Properties in Convective Drying of Kiwi and Eggplant
Authors: Guine Raquel P. F. , Brito Mariana F. S. , Ribeiro Jéssica R. P. 
Published: May 2017

Abstract
The present work aimed at studying the mass transfer properties of two plant foods, kiwi (a fruit) and eggplant (a vegetable). For this convective drying experiments were conducted at different temperatures (from 50 to 80 ºC) and an air flow rate of 0.5 m/s, using slices with 6 mm thickness for both products. For the mathematical modelling two different methods were used, one based on the thin layer model and the other based on the Fick’s second law of diffusion. The results obtained allowed concluding that different methodologies allowed to obtain different values of the mass transfer properties, so care must be taken when choosing an appropriate calculation method. Regarding the values of diffusivity and mass transfer coefficient, in all cases they were found to increase with increasing operating temperature. Both the activation energy and the activation energy for convective mass transfer were similar for kiwi and for eggplant, indicating that both foods behave in a very similar way when exposed to the drying conditions tested.

Published: May 2017

Abstract
Open pore porosity of spaghetti was measured by helium (He) gas pycnometer and mercury (Hg) porosimetry and it was observed as 0.025 and 0.023, respectively. Pore size distribution curve from mercury porosimetry indicated two sharp crests, at alternate position of 59±8 μm and 6.4±0.9 μm diameter pore; while Scanning Electron Microscopy (SEM) showed two types of pores, first class was cracks and second one was holes. The average width of the cracks (channel) and diameters of holes were determined as 3.6±1.5 µm and 1.0±0.3, respectively. The moisture sorption isotherm of spaghetti was measured by dynamic sorption method and modeled by Brunauer-Emmett-Teller (BET) and Guggenheim-Anderson-de Boer (GAM) models. The values of BET monomolecular layer were observed as 3.24 and 5.91 kg water/kg dry solids, respectively for adsorption and desorption cycles.
The comparative effectiveness of noticing in language learning
Authors: Cosgun Ögeyik Muhlise 
Published: May 2017

AbstractThe Noticing Hypothesis holds that input does not become intake during language learning unless it is noticed. The hypothesis has been tested and evaluated in many empirical studies for more than two decades, either supported or criticized. This study shares the findings on the comparative effectiveness of noticing treatments gathered and evaluated from various empirical studies that were carried out in different countries. The results of the studies reflect the potentials of noticing treatments in second language/foreign language -L2- instruction/learning and touch upon the validity of the Noticing Hypothesis. The results of the reviewed studies also showed that noticing through output oriented tasks generates higher level of perception of L2 knowledge.
Vocabulary acquisition and young learners: Different tasks, similar involvement loads
Authors: Silva Breno , Otwinowska Agnieszka 
Published: May 2017

AbstractLaufer and Hulstijn (2001) suggest that the motivational-cognitive construct ofinvolvementmay explain and predict different levels of effectiveness for vocabulary-learning tasks. Drawing on their original work and on later research on theinvolvement load hypothesis(ILH), this study set out to compare the effectiveness of carefully-designed tasks for incidental vocabulary acquisition in children. Thirty-eight EFL elementary-level 10-year-olds from a public school in Warsaw, Poland, participated in the experiment. Divided into three groups, the participants performed three different sequences of tasks, each sequence inducing similar levels of involvement load. In order to measure receptive lexical learning and retention of meaning and spelling, the children were tested with an orthography test, an L2-L1 translation test, and a multiple-choice test immediately after the treatment, and one week later. In support of the ILH, the MANOVA results showed no significant differences between the treatments (irrespective of them being input- or output-based) in any of the test measurements, either in the immediate or in the delayed posttest. We discuss the results in light of the ILH, and outline some limitations and possible implications for pedagogy.
Vowel quality alternation in Dinka verb derivation: The Agar variety
Authors: Andersen Torben 
Published: May 2017

AbstractIn Dinka, a predominantly monosyllabic and highly fusional Western Nilotic language, vowel quality alternation in the root plays a major and systematic role in the morphology of verbs, together with alternations in vowel length, voice quality, and tone. Earlier work has shown that in the inflection of simple, i.e., underived, transitive verbs, the vowel quality alternation conforms to a vowel height gradation system with three vowel grades. The present article shows that this vowel gradation system is also operative in the morphology of derived verbs with a transitive root, but with certain modifications. These include a different distribution of the vowel grades and interaction with a shift in voice quality, to breathy voice.
Prefixal vowel length in Lulamogi: A stratal account
Authors: Hyman Larry M. 
Published: May 2017

AbstractOver the past several decades there has been recurrent skeptism concerning cyclic derivations in phonology, one of the most central tenets of traditional generative and lexical phonology and morphology. In this paper I draw on original data from Lulamogi, a previously almost unstudied Bantu language of Uganda, to show that the most insightful analysis of some rather unusual vowel length alternations requires either cyclicity or global reference to internal morphological structure, specifically the difference between stem vs. prefix V+V sequences. After documenting the vowel length properties in some detail I consider several analyses, opting for a stratal account which neatly mirrors the traditional Bantu stem, word, and phrasal domains.
Pluralization, feminization and pitch accent in Djibouti Somali nouns
Authors: Lampitelli Nicola 
Published: May 2017

AbstractThe goal of this paper is to present newly collected data of Djibouti Somali and show how it offers insight into the architecture of nouns. Djibouti Somali, like Standard Somali, is characterized by the presence of inflectional classes. Building on my own fieldwork material, I discuss both the empirical statements and the theoretical implications that emerge from the observation of three aspects of noun inflection: (1) pluralization strategies, (2) the position of pitch accent with respect to gender and (3) the opposition between Absolutive and Nominative case. In particular, the fact that Djibouti Somali uses mainly two suffixes to pluralize nouns, leads us to the hypothesis that the inflectional system of this variety consists of only two inflectional types. Basic non-derived nouns belong to what I call type A, whereas suffixed nouns belong to type B. This dichotomy is confirmed by the behavior of pitch accent with respect to both gender and syntactic case. Finally, I propose that the distinction between type A and type B can be accounted for, in the context of a formal analysis, by postulating the existence of a contrast between null vs. overt nominalizer.
Case Report. The Use of Endotoxin Adsorption in Extracorporeal Blood Purification Techniques. A Case Report

Published: May 2017

Abstract
Sepsis and septic shock are major healthcare problems, resulting in high morbidity and mortality. The Surviving Sepsis Campaign (SSC), which standardised the approach to sepsis, was recently updated. Strategies to decrease the systemic inflammatory response have been proposed to modulate organ dysfunctions. Endotoxin, derived from the membrane of Gram-negative bacteria, is considered a major factor in the pathogenesis of sepsis. Endotoxin adsorption, if effective, has the potential to reduce the biological cascade of Gram-negative sepsis.
We present a case of a 64-year-old man with severe Gram-negative sepsis, following purulent peritonitis secondary to rectosigmoid adenocarcinoma. To reduce the amplitude of the general effects of endotoxins we used a novel device, the Alteco® LPS Adsorber (Alteco Medical AB, Lund, Sweden), for lipopolysaccharide (LPS) adsorption.
The efficacy markers were: the overall haemodynamic profile, translated into decreased vasopressor requirements, the normalisation of the cardiac index, the systemic vascular resistance index combined with the lactate level and the reduction in procalcitonin (PCT) levels. A decrease in the sequential organ failure assessment (SOFA) score at twenty-four hours was demonstrated.
The clinical course following treatment was favourable for the days immediately following the treatment.This was attributed to the removal of endotoxin from the systemic circulation. The patient died one week after the endotoxin removal session, developing an ischemic bowel perforation with subsequent multiple organ failures.
Case Report. Extracorporeal Membrane Oxygenation in Nivolumab Associated Pneumonitis
Authors: Schneider Thomas-Michael , Klenner Friederike , Brettner Franz 
Published: May 2017

Abstract
Background: Newly approved immunotherapeutic agents, like CTLA-4 inhibitors and antibodies against PD-1, are a promising therapeutic option in cancer therapy.
Case presentation: A 74-year-old man, with a history of advanced stage melanoma and treatment with ipilimumab, pembrolizumab and nivolumab, was admitted to the hospital due to respiratory failure with hypoxemia and dyspnoea. He rapidly developed severe acute respiratory distress syndrome (ARDS), which required treatment in the intensive care unit which included mechanical ventilation and extracorporeal membrane oxygenation (ECMO). Computed tomographic imaging (CT) showed signs of a pneumonitis, with an ARDS pattern related to the use of PD-1 antibodies. Treating the patient with high-dose immunosuppressive steroids led to an overall improvement. He was transferred to a rehabilitation hospital and subsequently to his home.
Discussion and conclusion: This is a unique case report of a patient suffering a grade 4 adverse event under nivolumab who survived having been treated with ECMO. It highlights the possibility of associated adverse reactions as well as the use of ECMO in palliative care patients. ECMO can be of great success even in patients with malignancies, but careful decision making should be done on a case by case basis.
Semi-automated process of adaptation of platform dependent parts of embedded operating systems
Authors: Vojtko Martin , Krajčovič Tibor 
Published: May 2017

Abstract
Each year manufacturers develop new processors. As a reaction to this continuous development, the developers of software have to adapt their software to those new processors. As a minimal requirement, the code of an operating system has to be changed to enable the execution of other user applications. This change is a complicated process during which incompatible parts of an operating system have to be redesigned and missing parts have to be implemented. Complications arise when there is a need to adapt an operating system to completely different processor architecture. In this paper we present a novel adaptation process that has preconditions to reduce the impact of these complications. This process uses a file for the formal description of a processor, which is also described in this paper. The formal description could act as a standard for processor manufacturers and could allow the generation of a platform dependent code of an operating system. This paper presents concepts, definitions and ideas of the adaptation process and shows possible solutions for an automatic generation of code parts of an operating system.
Analysis of sensorless control of brushless DC motor using unknown input observer with different gains
Authors: Astik Mitesh B. , Bhatt Praghnesh , Bhalja Bhavesh R. 
Published: May 2017

Abstract
A sensorless control scheme based on an unknown input observer is presented in this paper in which back EMF of the Brushless DC Motor (BLDC) is continuously estimated from available line voltages and currents. During negative rotation of motor, actual and estimated speed fail to track the reference speed and if the corrective action is not taken by the observer, the motor goes into saturation. To overcome this problem, the speed estimation algorithm has been implemented in this paper to control the dynamic behavior of the motor during negative rotation. The Ackermans method was used to calculate the gains of an unknown input observer which is based on the appropriate choice of the eigenvalues in advance. The criteria to choose eigenvalue is to obtain a balance between faster convergence rate and the least noise level. Simulations have been carried out for different disturbances such as step changes in motor reference speed and load torque. The comparative simulation results clearly depict that the disturbance effects in actual and estimated responses minimizes as observer gain setting increases.

Published: May 2017

Abstract
Propagation of a two-dimensional spatio-temporal electromagnetic beam wave is analysed. In parabolic (paraxial) approximation the exact analytical results for a spatio-temporal Gaussian impulse can be obtained. For solution of the full wave equation the numerical simulation has to be used. The various facets of this simulation are discussed here.
Systematic Prediction of the Impacts of Mutations in MicroRNA Seed Sequences
Authors: Bhattacharya Anindya , Cui Yan 
Published: May 2017

Abstract
MicroRNAs are a class of small non-coding RNAs that are involved in many important biological processes and the dysfunction of microRNA has been associated with many diseases. The seed region of a microRNA is of crucial importance to its target recognition. Mutations in microRNA seed regions may disrupt the binding of microRNAs to their original target genes and make them bind to new target genes. Here we use a knowledge-based computational method to systematically predict the functional effects of all the possible single nucleotide mutations in human microRNA seed regions. The result provides a comprehensive reference for the functional assessment of the impacts of possible natural and artificial single nucleotide mutations in microRNA seed regions.

Masculinity vs Femininity in Polish and Ukrainian Organisational Cultures
Authors: Szydło Joanna 
Published: May 2017

Abstract
One of the five cultural dimensions suggested by G. Hofstede, the dimension of masculinity and femininity, is very controversial. Defining cultures as feminine and masculine results in two issues. In the first, the content one, masculine cultures are characterised by “hard”, instrumental values, whereas feminine cultures by “soft” values whose core is the quality of interpersonal relations. In feminine cultures gender differences disappear, however, with the increase in the masculinisation of culture, the differences in the range of gender values grow. The article is of cognitive character. It shows the results of the research concerning the values and basic objectives in the range of dimensions of masculinity and femininity carried out in Polish and Ukrainian organizations.
The Monitoring of Protein Markers of Inflammation and Serum Lipid Concentration in Obese Subjects with Metabolic Syndrome
Authors: Sladoje Dragana Puhalo , Kisić Bojana , Mirić Dijana 
Published: May 2017

SummaryBackground: Obesity is one of the most common modern health problems worldwide. Proinflammatory cells accumulate in the adipose tissue of the obese, and the presence of a low level chronic inflammation in obesity is associated with the emergence of a range of metabolic disorders in cluding cardiovascular disease, insulin resistance, type-2 diabetes, fatty-liver disease, and others. Neutrophils are early parti - cipants in inflammatory processes. After the appropriate stimu lation, these cells release reactive oxygen and nitrogen species, which leads to degranulation and secretion of myeloperoxidase and other enzymes. Myelo per oxidase and its reactive oxidants contribute to tissue damage during inflammatory processes in the human body. Methods: The study included 175 subjects who were, in com - pliance with the International Diabetes Federation criteria, divided into 3 groups: normal weight subjects (N=106), subjects with abdominal obesity (N=37) and the third group consisted of subjects with the metabolic syndrome (N=32). Results: By analyzing the myeloperoxidase enzyme activity (kU/L), and the levels of high-sensitivity C-reactive protein in the blood of all subjects, we detected their significantly higher activity and levels in subjects with the metabolic syndrome, as compared to normal weight subjects (p<0.001). Conclusion: Based on our results, we can conclude that the MPO activity in the serum progressively increases with obesity and the metabolic syndrome, which indicates that this prooxidant enzyme may play a role in the pathophysiological mechanisms of the obesity and the metabolic syndrome related complications.
