Influence of Different Algal Diets on Larval Growth Rates in the Marine Serpulidae Polychaete Worm Spirobranchus kraussii
Authors: Lavajoo Fatemeh 
Published: July 2019

Abstract
Effects of food availability on larval growth and survival of Spirobranchus kraussii were studied by feeding larvae different algal diets. Newly hatched larvae of S. kraussii were fed four different marine microalgae species, singly and in various mixtures. The best growth was observed when fed C. vulgaris, N. oculata as a single species and mixed-algal diet during day 15 after fertilization. Mortality was low for larvae (max. 5%); survival rate more than 95%. These results suggest that S. kraussii larvae have the capacity to feed using alternative sources of energy, and food size and quality can affect their growth and sustainability.
Relation of economic and environmental indicators to the European Union Emission Trading System: a spatial analysis
Authors: Pászto Vít , Zimmermannová Jarmila 
Published: July 2019

Abstract
The main goal of this contribution is to evaluate the development of CO2 emissions and selected economic indicators of EU28 countries in the period from 2005 to 2015, and to capture geographical pattern and spatial distribution of countries emitting pollution. This will be performed within the context of the EU Emissions Trading System (ETS), which has represented a major scheme in Europe to cope with CO2 emissions since 2005. The actual situation in the field of the EU ETS is described and key scientific studies focusing on the EU ETS are presented. Based on a broad set of indicators we examine and evaluate possible geographical pattern in the development of selected indicators within the EU and provide detailed spatial analysis of economic and environmental data of EU28 countries, with the use of (geo)visual analysis of spatial data and spatial statistics (grouping analysis). The preliminary results of the (geo)visual analysis show that CO2 emissions within EU countries were decreasing in the selected period 2005–2015, with some exceptions (e.g. Iceland and Latvia). As the development of CO2 emissions in all EU countries is not similar, the other economic and environmental indicators were included (e.g. GDP, Investments) into the analysis in order to reveal a common (geographical) pattern and explain the current situation. Based on grouping/cluster analysis, it is possible to form territorial groups of EU states with similar development, which are almost perfectly in the line with current EU member states strategies of CO2 emissions trade. The current auction markets are well in tune with geographical and economic characteristics of particular EU countries. Results of grouping analysis of all indicators in 2015 using six K-nearest neighbours underline current separate auction markets for Germany, the United Kingdom and Poland.It indicates that the system of emission auctions has logical background and the markets represent natural platforms for emission trading, corresponding to both economic and spatial characteristics of particular countries/polluters. Presented approach thus brings valuable information for policymakers both on the national and international level for the next phases of EU ETS scheme planning.
Urban travel characteristics in relation with jobs-housing balance and accessibility: results of a survey in Lahore, Pakistan
Authors: Aslam S. Atif Bilal , Masoumi Houshmand E. , Hussain Syed Arif 
Published: July 2019

Abstract
The circumstances of the relations of jobs-housing balance and urban travel behavior are not clear in emerging and developing countries. There are limited reliable data suitable for testing the hypotheses regarding the associations of the neighborhood-level number of employment opportunities in these countries. This manuscript summarizes the results of an explorative survey undertaken in Lahore, Pakistan to support empirical analyses testing these hypotheses. The survey was undertaken in spring 2018 in six neighborhoods of Lahore and collected the data of 417 respondents. The short questionnaire applied in the survey facilitated generation of 15 individual and household, socioeconomic, and mobility-related variables of different types. Moreover, 9 land use variables as well as jobs-housing ratios were estimated for each respondent within his/her 600-meter street-network pedestrian shed. The produced dataset reveals preliminary descriptive statistics about the relations of employment and travel behavior, particularly commuting, in a less-studied context of Pakistan. It is found that a decent job-housing balance at neighborhood scale alone cannot affect the travel pattern much in the Pakistani context. It needs to be supplemented with other planning interventions, mainly the accessibility to an integrated and efficient mass public transportation system, discouraging private car based policies and promotion of sustainable non-motorized travel modes. In the future, production of disaggregate mobility and land use data will add value to urban transportation research in the Global South.

On some parabolic problems with measure sources
Authors: Abdellaoui Mohammed 
Published: July 2019

Abstract
One of the recent advances in the investigation of nonlinear parabolic equations with a measure as forcing term is a paper by F. Petitta in which it has been introduced the notion of renormalized solutions to the initial parabolic problem in divergence form. Here we continue the study of the stability of renormalized solutions to nonlinear parabolic equations with measures but from a different point of view: we investigate the existence and uniqueness of the following nonlinear initial boundary value problems with absorption term and a possibly sign-changing measure data

Published: July 2019

Abstract

Background
Patients with sleep apnea syndrome (SAS) and heart failure (HF) have concomitant different comorbidities and increased risk of morbidity.

Aim
The aim of this study was to analyze differences between patients with SAS and heart failure with preserved ejection fraction (HFpEF; ejection fraction [EF]≥50%) – group 1 and those with SAS and heart failure with reduced ejection fraction (HFrEF; EF<50%) – group 2.

Methods
We evaluated 51 patients with SAS and HF in the sleep laboratory of Timisoara Victor Babes Hospital. We collected general data, sleep questionnaires, anthropometric measurements (neck circumference [NC], abdominal circumference [AC]), somnography for apnea–hypopnea index (AHI), oxygen desaturation index (ODI), echocardiographic data, comorbidities, and laboratory test.

Results
The study included 51 patients who were divided into two groups depending on EF, with the following characteristics: Group 1 (HFpEF): 26 patients, 19 males, seven females, age 61.54±9.1 years, body mass index (BMI) 37±6.4 kg/m2, NC 45.4±3.6 cm, AC 126.6±12.9 cm, AHI 48.3±22.6 events/hour, central apnea 5.6±11.4 events/hour, obstructive apnea 25.7±18.7 events/hour, ODI 41.2±21.2/hour and lowest SpO2 –72.1±14%.
Group 2 (HFrEF): 25 patients, 18 males, seven females, age 63.6±8.8 years, BMI 37.9±7.5 kg/m2, NC 46±4.4 cm, AC 127.2±13.9 cm, AHI 46.4±21.7 events/hour, central apnea 4.6±8.3 events/hour, obstructive apnea 25.9±18.5 events/hour, ODI 44.8±27.1/hour and lowest SpO2 –70.6±12.1%. Differences between groups regarding anthropometric and somnographic measurements and lipidic profile were not statistically significant.
Significant differences were observed regarding stroke (23% vs. 4%, p=0.04) in the group with HFpEF and regarding creatinine measurements (1.1±0.2 vs. 1.4±0.7, p=0.049), aortic insufficiency (11.5% vs. 36%, p=0.04) and tricuspid insufficiency (6.1% vs. 80%, p=0.01) in the group with HFrEF.

Conclusions
Patients with SAS and HFpEF have a higher risk of stroke. Patients with SAS and HFrEF have a significantly increased risk of developing a life-long chronic kidney disease and aortic and tricuspid insufficiency. These results may suggest pathogenic links between SAS and the mentioned comorbidities, and this may explain the higher mortality when this association is present.
Deterministic and Probabilistic Approaches in the Analysis of the Bearing Capacity of a Bridge Foundation on Undrained Clay Soil
Authors: Muhammed Jemal J. 
Published: July 2019

Abstract
This study aims at evaluating deterministic and probabilistic approaches for an analysis of the bearing capacity of a highway bridge foundation on undrained clay soil. The analysis of a rectangular concrete footing was presented for the ultimate strength limit state of the bearing resistance according to the formulation in ES EN 1991:2015 and ERA-Bridge Design Manual, which are the Ethiopian design codes for foundation structures. In the deterministic analysis, the traditional total safety factor method recommended by the ES EN 1991:2015, ERA and AASHTO LRFD method was implemented. It was assumed that design variables such as the soil parameters and loads would follow normal and lognormal distribution functions. With regard to the probabilistic methods, NESSUS-9.8 software, a statistical computer program, was used for the analysis. Comparisons were made between the results obtained from the traditional deterministic method and the reliability-based design approach. The evaluation asserts that the probabilistic approach is a better tool than the deterministic one for assessing the safety and reliability of geotechnical structures. The probabilistic design method rationally accounts for uncertainties more than the conventional deterministic method does. Thus, the author recommends that the National Design Codes of Ethiopia need to be revised and calibrated based on a reliability design format.

Industri batik printing memproduksi tekstil bermotif batik dengan cara menduplikasinya melalui mesin-mesin printing, sehingga proses pengerjaannya bisa lebih cepat serta harga jual yang lebih murah dan ini memberikan ancaman bagi perkembangan batik asli. Ditambah lagi ketidaktahuan masyarakat dalam membedakan antara batik asli dan produk tekstil bermotif batik, telah menyebabkan masyarakat rentan dengan upaya penipuan oknum penjual batik dan memunculkan kecenderungan membeli produk tekstil bermotif batik yang harganya lebih murah. Untuk itu, diperlukan suatu alat bantu berupa aplikasi yang dapat digunakan oleh masyarakat untuk mengenali keaslian batik, sekaligus sebagai media belajar tentang berbagai hal terkait batik asli. Dari hasil diskusi dengan para penjual batik, diharapkan aplikasi tersebut mampu menampilkan informasi keaslian batik yang mudah dibaca serta memiliki kecepatan tampil yang stabil, walau diambil dari jarak pindai yang berbeda serta sudut kemiringan yang berbeda, sehingga dalam penelitian ini, diputuskan untuk menggunakan library AR.js dalam aplikasi e-label batik.Abstract The batik printing industry produces batik-patterned textiles by duplicating them through printing machines, thus the process may be faster and the selling price is cheaper, and this poses a threat to the development of original batik. The ignorance of the community in distinguishing between original batik and textile products with batik motifs, has caused the community to be vulnerable to fraudulent attempts from the sellers of batik and led to the tendency to buy batik-patterned textile products at a lower price. Hence, needed a tool in the form of applications that can be used by the public to recognize the authenticity of batik, as well as a medium of learning about various things related to original batik. The discussions with batik sellers resulted that the application is expected to be able to display the authenticity information on batik that is easy to read and has a stable speed in displaying messages, even though taken from different scan distances and different slope angles, thus in this study, it was decided to use the library.

Memoria y mismidad. Análisis desde la fenomenología-hermenéutica de Paul Ricoeur
Authors: Quiceno Osorio Juan David 
Published: July 2019

Para Paul Ricoeur, Derek Parfit es un excelente representante de la tradición basada en la identificación que Locke realiza entre memoria e identidad. Esta identificación, que eclipsa además la pregunta por el quién de la acción, permite llevar la identidad humana hacia un callejón sin salida en el que solo es viable el abandono de una preocupación que aparecería como una aporía. Como el mismo Parfit declara en su obra, la identidad no es algo que interese. Además, la tecnología moderna y los sueños del post-humano, que se inspiran en la ficción literaria del siglo XX, trabajan apoyados en esta identificación proveniente del empirismo, y parecen reforzar la idea de dicha coincidencia y, en nuestro concepto, a ayudar a empobrecer cada vez más la noción de memoria. El artículo se centra en primer lugar, en el análisis que Ricoeur realiza de la memoria intentando enriquecer su reflexión desde una perspectiva hermenéutica. En segundo lugar, en el contraste con la reducción empírica de la memoria y en el intento de sugerir algunos argumentos que permitan llevarla un poco más allá del dato biológico y psíquico.

Осложнения гестационного периода у женщин с оперированными яичниками в анамнезеЦелью работы было оценить влияние хирургического вмешательства на репродуктивное здоровье пациенток путем анализа гестационных осложнений у женщин с овариальной патологией в анамнезе.Материалы и методы. Изучены индивидуальные карты, в том числе истории родов 420 беременных с доброкачественными образованиями яичников/опухолевидными образованиями яичников, апоплексией, синдромом поликистозных яичников за период с 2013 по 2016 год.Результаты. Наиболее частыми осложнениями гестационного периода у пациенток с овариальной патологией в анамнезе были: угроза прерывания беременности, анемия, кольпит, преэклампсия, плацентарные нарушения. Анализ показал наличие целого ряда значимых отличий в группе у беременных с доброкачественными образованиями яичников/опухолевидными образованиями яичников: угроза раннего аборта и плацентарные нарушения в подгруппе у женщин с оперативным лечением встречалась в три раза чаще, чем с консервативным подходом; угроза позднего аборта выявлена у каждой третей, а угроза преждевременных родов и преэклампсия у каждой пятой пациентки с оперированными яичниками в анамнезе. Синдром задержки внутриутробного развития плода в 6 раз чаще выявлялся в подгруппе у беременных с хирургическим подходом, в отличие от женщин с консервативным лечением.Вывод. Оперативное лечение, в анамнезе по поводу доброкачественных образований яичников/опухолевидных образований яичников, значимо повышало у беременных риски угрозы прерывания гестации, преэклампсии, плацентарных нарушений, синдрома задержки внутриутробного развития плода, репродуктивных потерь в виде самопроизвольных абортов.

Student’s school well-being is one of the factors that determine the extent to which the quality of education can be felt effectively by all individuals in it. The concept of wellbeing arises because of the overall collaboration and mutual support among the elements of education in schools. One of the factors that contribute to the student’s school wellbeing is academic integrity. Academic integrity refers to the tendency of students to behave as the values of truth that they believe in and in accordance with the demands of the environment. This study aims to examine the influence and contribution of academic integrity to the well-being of students at school. The quantitative research design by testing of regression assumptions was carried out in this study. The subjects involved in this study amounted to 186 participants by being selected based on the random sampling method. The results of the study indicate that academic integrity moderately influences the well-being of students at school. This assumes that personal factors such as academic integrity are needed to support the quality of effective learning, because learning outcomes depend on how the mental and psychological conditions of the students themselves.Abstrak Kesejahteraan siswa di sekolah menjadi salah satu faktor yang menentukan sejauhmana kualitas pendidikan itu bisa dirasakan efektif oleh seluruh individu yang ada di dalamnya. Kesejahteraan muncul karena adanya kolaborasi yang menyeluruh dan saling mendukung di antara elemen pendidikan di sekolah. Salah satu faktor yang ikut berperan terhadap kesejahteraan siswa di sekolah adalah integritas akademik. Integritas akademik mengacu kepada kecenderungan siswa untuk bersikap dan bertingkah laku sebagaimana nilai kebenaran yang mereka yakini dan sesuai dengan tuntutan lingkungan. Penelitian ini bertujuan untuk menguji pengaruh dan kontribusi integritas akademik terhadap kesejahteraan siswa di sekolah. Desain penelitian kuantitatif dengan pengujian asumsi regresi dilakukan dalam penelitian ini. Subjek yang terlibat dalam penelitian berjumlah 186 partisipan dengan dipilih berdasarkan metode random sampling. Hasil penelitian menunjukkan bahwa integritas akademik secara moderat mempengaruhi kesejahteraan siswa di sekolah. Hal ini mengasumsikan bahwa faktor personal seperti integritas akademik dibutuhkan dalam menunjang kualitas pembelajaran yang efektif, karena hasil belajar itu tergantung pada bagaimana kondisi mental dan psikologis siswa itu sendiri
