Authors: Schovsbo Niels H. , Nielsen Arne T. , Erlström Mikael
Published: April 2020

A complete log-stratigraphical breakdown of the Middle Ordovician to lower Silurian shale-dominated succession is presented for the Bornholm–Skåne–Kattegat area in southernmost Scandinavia. A wireline log zonation developed for the onshore Bornholm Palaeozoic shales is extended to include the offshore Palaeozoic shales in the adjacent Rønne Graben. A complete log zonation scheme for the Cyrtograptus shale (late Llandovery–Wenlock) and the lower part of the Colonus shale (Ludlow) is presented including correlation within the Bornholm–Skåne–Kattegat area. The Cyrtograptus shale in the Bornholm area is estimated to be 400 m thick and marks the shift to a rapidly subsiding foreland basin, heralding the Caledonian Orogeny.

Authors: YENİGÜL Nefise Nazlı , GÜNEŞ Ahmet Kürşat , BULDUM Dilek
Published: April 2020

Amaç: Gebelerdeki trombositopeni kadın doğum uzmanları için hematolojik komplikasyonlar arasında belki de en tedirgin edicisidir. Doğum ve anne ölüm oranları ülke ortalamasının üzerinde olan ilimizdeki gebelerde görülen hematolojik hastalıklarla ilgili yapılmış çalışma yoktur. Bu yüzden çalışmamızda ilimizdeki kadın doğum uzmanlarının hematolojiye konsülte ettikleri trombositopenik gebelerin genel özelliklerini değerlendirmek, etyolojilerini ve insidansını belirlemek ve bu konudaki farkındalığı arttırmayı amaçladık. Materyal ve Metod: Çalışmaya 18-44 yaş arası rutin hemogramlarında trombositopeni saptanan ve ildeki tek hematoloji polikliniğine konsülte edilen 122 gebe dahil edildi. Hastaların şu parametreleri değerlendirildi; anne yaşı, gebelik haftası, başvurudaki trombosit sayısı, kanama olup olmaması, periferik yayma sonucu konulan tanılar, uygulanan tedaviler ve ikinci basamak tedavi ihtiyacı.Bulgular: Hastaların ortalama yaşları 26.0±4.8, gebelik haftaları 27.4±8.1, ortalama trombosit sayıları ise 79.000±52.300/mikroL idi. 65 hastaya (%53.3) gestasyonel trombositopeni, 27 hastaya (%22.1) idiyopatik trombositopenik purpura, 13 hastaya (%10.7) psödotrombositopeni, 4 (%3.3) hastaya HELLP (hemoliz, artmış karaciğer enzimleri, düşük trombosit sayısı), 4 (%3.3) hastaya akut lösemi, 4 (%3.3) hastaya Bernard Soulier Sendromu, 2’şer hastaya (%1.6) dissemine intravasküler koagülopati ve megaloblastik anemi ve 1 hastaya Evans Sendromu tanısı konuldu. Konsülte edildiğinde kanaması olan 19 gebe ve kanaması olmayan 103 kadının gebelik haftaları ve trombosit sayıları ise anlamlı şekilde farklıydı (p<0.001).Sonuç: İlimizdeki gebelerde karşılaşılan trombositopenilerin çoğu obstetrilk kaynaklı olsada, erken dönemde ciddi trombositopeni ile seyreden gebelerde hematoloji kökenli nadir hastalıklar da olabilir. Bu sebeple ilimizde erken dönemde başvuran ve ciddi trombositopenisi olan gebelerin yaşam şansını arttırmak ve tanılarının erken ve doğru bir şekilde koyulabilmesi için hızlıca hematoloji polikliniğine konsülte edilmeleri önemlidir.

Authors: AKSAN Gökhan , YONTAR Osman Can , YANIK Ahmet
Published: April 2020

Atrial tachycardias (AT) originating from right atrial appendage (RAA) are quite rare among focal atrial tachycardias. A 38-year-old female patient presented to the emergency room complaining of palpitations and dizziness. Electrocardiography (ECG) showed regular narrow QRS complex tachycardia with a ventricular rate of 150 bpm. The patient had frequent episodes of palpitations for 5 years. Considering the ensuing tachycardiomyopathy under medical treatment, electrophysiological study (EPS) and ablation procedure was planned after having informed consent. During isoproterenol infusion (1-4 mcg/min), a sustained tachycardia with narrow QRS complex was induced. Diagnostic electrophysiological findings were consistent with AT. During tachycardia, by using a three-dimensional (3D) electroanatomic mapping system, simultaneous anatomical and activation mapping was performed with a quadripolar 3.5mm cooled-tip Thermocool Smarttouch bi-directional navigation catheter. Activation mapping demonstrated that the earliest endocardial activation site was basal portion of the RAA where the local electrogram was 104 msn prior to the Cs reference signal during tachycardia which is spreading in a centrifugal fashion. Impedance-controlled radiofrequency ablation (RF) ablation (35 W, 42° C, 5-10 g of contact force) was performed at the earliest site and tachycardia terminated in 10 seconds. No AT observed during the waiting period of 30 min after RF ablation.

A Student Primer On How to Thrive in Post-COVID-19 Engineering Education
Authors: Qadir Junaid , Al-Fuqaha Ala
Published: April 2020

In this paper, we strive to provide a primer for students on how to thrive and learn effectively in engineering education in the volatile, uncertain, complex, and ambiguous (VUCA) times following the onset of the COVID-19 global pandemic, which has disrupted the educational enterprise massively with universities physically closing in many parts of the world and students and faculty transitioning to remote learning. While our immediate focus in this paper is on engineering education functioning in an outcome-based education (OBE) environment, the global paradigm mandated by the Washington Accord that aims to standardize engineering competencies in terms of the attained student learning outcomes, our ideas are general and broadly useful for learners of all types. We will describe seven evidence-based steps that the students can adopt to thrive in OBE settings in these challenging times. The main contribution of this paper is practical: we present a synthesis of the vast research literature on effective student learning in normal, online, and disrupted settings to present practical insights that students can leverage to substantially improve their learning.
Construcciones identitarias migrantes: identidades en resistencia e identidades estratégicas en niños y niñas haitianos en Santiago de Chile
Authors: Ibáñez Karen
Published: April 2020

In recent years, the arrival of the Haitian population in Chile has been increasing and has been characterized by a complex process of social insertion, which has had repercussions in the field of education. In this regard, this study is situated in the field of cultural conflict by seeking to interpret the identity constructions experienced by children from Haiti on the basis of social practices and perceptions of the socio-educational environment in a school in Santiago de Chile, from the conceptualization of difference and intersectionality in migration. In this way, it is realized that children from Haiti build their identities from identities in resistance and strategic identities. To account for this, the research is based on the thesis of the degree in anthropology. A qualitative methodological strategy was developed through school ethnography with a year-long field work, in which participant observation and in-depth interviews were conducted. The aim was to highlight a critical stance with respect to the importance of rescuing the perspective of children and their capacity for agency.

Introducción: Uno de los mayores avances de las últimas décadas en la cirugía de tórax ha sido el desarrollo de la cirugía mínimamente invasiva.Objetivos: Describir la experiencia en videotoracoscopía (VATS) uniportal de miembros del equipo de Cirugía de Tórax de la Universidad de Chile en 2 campos clínicos, (Clínica Las Condes y Hospital Clínico de la Universidad de Chile).Material y métodos: Se estudiaron 105 pacientes sometidos a VATS uniportal entre enero de 2016 y enero de 2019. Los datos se analizaron de manera retrospectiva considerando variables demográficas (edad, sexo) y clínicas (diagnóstico, cirugía, estadía hospitalaria, días de pleurostomía, conversión, y complicaciones).         Resultados: De las 105 cirugías realizadas, 28 (26,6 %) correspondieron a cirugías mayores complejas lobectomías y segmentectomías anatómicas. En 4 pacientes se agregó un 2º puerto, uno se convirtió a mini toracotomía y uno a toracotomía (5,7% conversión global). La estadía hospitalaria fue en promedio 3,07 ± 3,1 días y el promedio de mantención de pleurostomía de 2,67 ± 1,61 días. Siete pacientes (6,6%) presentaron complicaciones post operatorias. Un paciente falleció por progresión de su enfermedad, no hubo mortalidad relacionada a la cirugía.Discusión: Las contraindicaciones de la VATS uniportal son las mismas que en la VATS multipuerto. En manos experimentadas, las complicaciones en cirugía por puerto único son bajas. Impresiona tener menos dolor post operatorio, menor estadía hospitalaria y reintegración precoz a las actividades diarias comparado con la VATS tradicional.Conclusiones:  Se presenta la primera serie de VATS uniportal publicada en Chile. Los resultados obtenidos son comparables a los observados en la literatura. Su implementación y desarrollo requiere de una curva de aprendizaje similar a cualquier nueva técnica quirúrgica.

The global economy rapidly evolves from a labor-based economy to an information-based economy. In parallel to the technological advancement, societal changes have reshaped the behaviour of end-user in acting in technology. Unlike 20 years ago, users’ are very keen to have active participation with Web technologies. The number of applications being used infers to a growing number of data and information circulation, thus creating data-driven market environment. Though centralized-approach is more preferable in most cases, however, with the growing number of usage, it is prone to single point of failure. This paper present a decentralized system design using Microservice Architecture approach. The use case of the design is for financial reporting system within an organization. Web services, REST-API technology, is adopted to ensure the interoperability of each sub-systems. A design of repository of service is also proposed to help catalogue and managing available services, thus making the proposed design scalable for future development.

Slavoj Žižek, Pandemic! COVID-19 Shakes the World
Authors: Ali Shehzad
Published: April 2020

One of the major themes of the book is to recognize the seriousness of the situation and its possible outcomes. Žižek informs us that the only possible way to face the challenge is to realize that world leaders should unite and develop a global health care system presided over by the World Health organization. As it is obvious that almost every crisis creates opportunities of some kind Žižek seems to argue that in the current disaster there is potential for communism (though not the one of 20th century type but the one) based on human cooperation. As he says: “it should be a disaster communism as an antidote to the disaster capitalism.”

Pendidikan yang akan mengubah menuju ke arah yang lebih baik adalah pendidikan yang kualitasnya baik pula. Tetapi melihat realitas sekarang, kualitas pendidikan di Indonesia masih rendah apalagi dalam hal pemerataan pendidikan,di antaranya: fasilitas, akses, dan tenaga pengajar yang akan berimplikasi pada proses belajar dan hasil belajar, keadaan tersebut salah satunya gambaran pendidikan yang ada di daerah terpencil. Dengan demikian, penelitian ini akan berfokus pada masalah pemerataan pendidikan di daerah terpencil dengan cara mengoptimalkan komunitas sobat mengajar sebagai gerakan sosial pendidikan. Komunitas ini bergerak di daerah-daerah terpencil khususnya di Kabupaten Lebak, Provinsi Banten, kajian awal mencari data keadaan pendidikan di daerah tersebut dengan cara membaca literature dan wawancara langsung kepada relawan sobat mengajar kemudian hasilnya dideskripsikan, dengan demikian penelitian ini menggunakan metode deskriptif kualitatif. Untuk mengatasi tidak meratanya pendidikan di Indonesia ada beberapa langkah yang harus dilakukan: pertama, mengoptimalkan gerakan sosial pendidikan. Kedua, melakukan program yang mengedukasi masyarakat. Ketiga, harus melibatkan masyarakat dalam semua program.

Abstract-Education is a human process, either an individual or a society towards an ideal and better life. Education that will change for the better is education that is of good quality too. But look at the current reality, the quality of education in Indonesia is still low especially in terms of equitable education for example lack of facilities, access, and teaching staff that will have implications for the learning process and learning outcomes, they are one picture of the conditions that exist in remote areas. Therefore, this research will focus on the problem of equitable education in remote areas by optimizing the community of sobat mengajar as a social education movement. This community is moving in remote areas especially in lebak regency, the province of banten, early studies looking into educational conditions in the region, the initial study looked for data on the state of education in the area by reading literature and direct interviews with volunteers of sobat mengajar then the results were described, thus this study using a descriptive qualitative methods. To overcome the unequal education in Indonesia, several steps must be taken: the first, optimize the social education movement. The secondis tocarry out programs that educate the public. The third is must involve the society in all programs.

Abstract
Several preclinical studies suggested a potential benefit from combined treatment with inhibitors of epidermal growth factor receptor (EGFR) and angiogenesis, both effective in patients with advanced non-small-cell lung cancer (NSCLC). In pretreated patients with advanced EGFR wild type NSCLC, bevacizumab plus erlotinib improved progression-free survival as second-line therapy in the BeTa study and as maintenance therapy in the ATLAS trial, although the benefit was modest and did not translate into an advantage in overall survival. Disappointing results were reported with oral VEGF inhibitors plus erlotinib in pretreated patients with EGFR wild type NSCLC. On the contrary, erlotinib plus bevacizumab or ramucirumab showed a clinically relevant improvement of progression-free survival in naïve patients with EGFR mutations, leading to the approval of these two regimens as first-line treatment of NSCLC patients with EGFR mutant tumors. Several clinical studies are evaluating the feasibility and activity of osimertinib plus bevacizumab or ramucirumab. However, limits that could affect its use in clinical practice are the need of an intravenous infusion for angiogenesis inhibitors, the increased incidence of treatment associated adverse events, the exclusion of patients with tumors located in central position or at risk of hemorrhage. The identification of predictive biomarkers is an important goal of research to optimize the combined use of these agents.

New ortho-alkoxy analogs of the compound ALM-802 1a (N1-(2-methoxybenzyl)-N2-[2-((2-methoxybenzyl)amino)ethyl]ethane-1,2-diamine trihydrochloride) and 1b (N1-(2-ethoxybenzyl)-N2-[2-((2-ethoxybenzyl)amino)ethyl]ethane-1,2-diamine trihydrochloride), which differ from it by the presence of alkoxy groups in the phenyl rings only in the ortho positions. It was established that these structural changes lead to the disappearance of anti-ischemic activity. At the same time, antiarrhythmic activity was revealed in compound 1b on the models of aconitine and calcium chloride arrhythmias in rats (1 mg / kg, intravenously), which was absent in 1a.

FAKTOR PENENTU KUALITAS AUDIT DI KANTOR AKUNTAN PUBLIK DKI JAKARTA
Authors: Momon Momon , Rachbini Widarto , Amilin Amilin
Published: April 2020

The study aims to analyze the effect of auditor competence and independence on audit quality. The sample used in this study were 151 samples (KAP) represented by the Auditor in DKI Jakarta. Data analysis uses descriptive and inferential analysis using multiple regression analysis. Hypothesis testing results indicate that there is a significant positive effect on Auditor Competence and Auditor Independence on Audit Quality. These results indicate that the higher (both) Auditor Competency and Auditor Independence, the Audit Quality will increase. Independent auditors should pay attention to their competencies. To improve audit quality, it is necessary to increase the competence of auditors by providing training and certification of expertise that supports the auditor profession in line with continuing professional education (PPL) programs. The role of regulators and accountants' associations (IAPI, IAI) in this case is also very necessary to monitor the implementation of the PPL program for auditors (accountants). Auditors who conduct audits must truly maintain and ensure independence both in fact and in appearance in order to produce quality audits. The existence of regulations that limit the length of the audit of a client conducted by the same public accountant, should also be supported by the KAP to rotate the auditor team, not only limited to the level of partners signing the audit report to further maintain its independence.

The search for life on exoplanets is one of the grand scientific challenges of our time. The strategy to date has been to find (e.g., through transit surveys like Kepler) earthlike exoplanets in their stars’ habitable zone, then use transmission spectroscopy to measure biosignature gases, especially oxygen, in the planets’ atmospheres (e.g., using James Webb Space Telescope (JWST)). Already there are more such planets than can be observed by JWST, and missions like the Transiting Exoplanet Survey Satellite and others will find more. A better understanding of the geochemical cycles relevant to biosignature gases is needed, to prioritize targets for costly follow-up observations and to help design future missions. We define a Detectability Index to quantify the likelihood that a biosignature gas could be assigned a biological versus nonbiological origin. We apply this index to the case of oxygen gas, O2, on earthlike planets with varying water contents. We demonstrate that on earthlike exoplanets with 0.2 weight percent (wt%) water (i.e., no exposed continents) a reduced flux of bioessential phosphorus limits the export of photosynthetically produced atmospheric O2 to levels indistinguishable from geophysical production by photolysis of water plus hydrogen escape. Higher water contents >1 wt% that lead to high-pressure ice mantles further slow phosphorus cycling. Paradoxically, the maximum water content allowing use of O2 as a biosignature, 0.2 wt%, is consistent with no water based on mass and radius. Thus, the utility of an O2 biosignature likely requires the direct detection of both water and land on a planet.
The Driving Scale–Density Decorrelation Scale Relation in a Turbulent Medium
Authors: Bialy Shmuel , Burkhart Blakesley
Published: April 2020

Density fluctuations produced by supersonic turbulence are of great importance to astrophysical chemical models. A property of these density fluctuations is that the two-point correlation function decreases with increasing scale separation. The relation between the density decorrelation length scale (L
dec) and the turbulence driving scale (L
drive) determines how turbulence affects the density and chemical structures in the interstellar medium (ISM), and is a key component for using observations of atomic and molecular tracers to constrain turbulence properties. We run a set of numerical simulations of supersonic magnetohydrodynamic turbulence, with different sonic Mach numbers (

), and driven on varying scales (1/2.5, 1/5, 1/7) the box length. We derive the L
dec–L
drive relation as a function of Mach number, driving scale, and the orientation of the line-of-sight (LOS) in respect to the magnetic field. We find that the mean ratio L
dec/L
drive = 0.19 ± 0.10, when averaged over snapshots, Mach numbers, driving lengths, and the three LOSs. For LOS parallel to the magnetic field the density structures are statistically smaller and the L
dec–L
drive relation is tighter, with L
dec/L
drive = 0.112 ± 0.024. We discuss our results in the context of using observations of chemical tracers to constrain the dominant turbulence driving scale in the ISM.
A second remarkable case of parapatry in a Tasmanian millipede genus (Diplopoda, Polydesmida, Dalodesmidae)
Authors: Mesibov Robert
Published: April 2020

Tasmaniosoma armatum Verhoeff, 1936 and T. orientale Mesibov, 2010 are parapatric in northeast Tasmania, Australia. The parapatric boundary is ca 50 km long and mainly follows streamlines. Three sections of the boundary were intensively sampled. Two gonopod variants of T. orientale also appear to be parapatric.

Until now, morphological trait variation has been investigated in several millipede species using geometric morphometrics. The present study is the first attempt to explore sexual shape and size dimorphism (SShD and SSD) of morphological structures in Polydesmida. We here analyse antennal, head, and leg SShD and SSD inBrachydesmus troglobiusDaday, 1889. Our results show that SSD exists in all of the analysed structures, while SShD is present only in the legs. In comparison with females, males possess longer and wider legs, as well as longer antennae and a shorter head. Contrary to previous findings in some Julida, inB. troglobiusSSD of the antennae and legs varies more than SShD in these morphological structures.
Character of woodland fragments affects distribution of myriapod assemblages in agricultural landscape
Authors: Horňák Ondřej , Mock Andrej , Šarapatka Bořivoj , Tuf Ivan Hadrián
Published: April 2020

Fragments of woodland fulfil many irreplaceable functions in the agricultural landscape including being the main source of biodiversity of soil invertebrates. Due to intensive farming and land use changes, especially in the second half of the 20th century, fragments of woodland in agricultural landscape almost disappeared. This has led to a decrease in the diversity of invertebrates, especially those for which the presence of these woodland habitats in the landscape is a key element for survival. The aim of this study was to evaluate the importance of fragments of woodland (characterised by their area, vegetation structure, the amount of leaf litter layer and soil moisture) on the distribution of centipedes and millipedes (Myriapoda) in the agricultural landscape of South Moravia (Czech Republic). Myriapods were collected using pitfall traps during summer in 2016 and 2017. Results showed that activity-density of myriapods is positively correlated with thickness of the leaf litter layer. Moreover, the species richness of centipedes is positively correlated with increasing size of fragments of woodland although higher centipedes’ activity-density was found in rather uniform woodlands in term of diversity of tree species.
