Improved algorithm for enhance robustness of IPTV based on GEPON
Authors: Li Li , Li Hong-Jie 
Published: March 2021

Abstract
Ten Gigabit-capable ethernet passive optical network (GEPON) can quickly improve network bandwidth, meet multilevel business needs, and quickly improve the comprehensive competitiveness of the network. It is well known that the 10G EPON access network technology is used to carry IPTV services, VoIP services and high-speed Internet access, known as “triple play”, and IPTV services have been particularly popular in recent years. As the demand for IPTV service increases exponentially, a large amount of data will be generated, occupying a large access bandwidth and causing an impact on other services. Therefore, reasonable scheduling of IPTV service queue is an urgent problem to be solved under multiservice environment at present. Therefore, the design of PON bearing IPTV robustness algorithm to meet user experience is the focus of this paper. This paper proposes a Forward Error Correction with Weight Round Robin algorithm (FWRR), which adopts RS error correction code and Weighted Round Robin algorithm based on IP layer. When IPTV packet is lost at optical line terminal (OLT) end, downlink optical network unit (ONU) can recover the lost data through received packets. This mechanism can effectively solve the problem of packet loss caused by the blocking of OLT end, and realize the scheme of PON carrying IPTV multicast service. Simulations results in OPNET show that compared with weighted round robin (WRR) algorithm and round robin (RR) algorithm, FWRR mechanism can reduce packet loss, delay and jitter, in addition, improve the robustness of IPTV service in GEPON.

Authors: Ziemer Benjamin 
Published: March 2021

Abstract
The article by Torleif Elgvin in ZAW 132/2 (2020): 281–300 fails in the material reconstruction of 1QSam. Considering the different width of the columns correctly, the manuscript could well have contained all parts of 2Sam 20–23 which makes further speculations superfluous.
Neural Network Modeling for the Rotational Viscosity of Reacted and Activated Rubber-Modified Binders
Authors: Isied Mayzan , Souliman Mena I. 
Published: March 2021

Abstract
Crumb rubber surface activation and pretreatment are considered one of the promising newly introduced methods for asphalt rubber production. Reacted and activated rubber (RAR) is an elastomeric asphalt extender produced by the hot blending and activation of crumb rubber with asphalt and activated mineral binder stabilizer. Besides RAR’s ability to enhance the performance of asphaltic mixtures, its dry granulate industrial form enables its addition directly into the mixture utilizing the pugmill or dryer drum with very minimal to no modification required on the plant level. This study aims to develop an artificial neural network (ANN) viscosity prediction model for extracting a standalone viscosity prediction equation. Three different performance graded (PG) asphalt binders modified by 10 dosages of RAR were tested and evaluated under this study. Sixty-six samples that generated more than 3,000 viscosity data points were utilized in ANN modeling. The developed ANN model as well as the extracted standalone viscosity prediction equation had a high value of the coefficient of determination and were statistically valid. Both have the ability to predict the RAR-modified binder viscosity as a function of binder grade, temperature, testing shearing rates, and RAR content.
Einspruch oder Worin besteht die Möglichkeit des Politischen auf dem Theater? Zum Verhältnis von Politik und Theater in der Performance Fight Night von Ontroerend Goed und The Border Project
Authors: Müller Frank Max 
Published: March 2021

Die Performance Fight Night, eine Kooperation zwischen der belgischen Gruppe Ontroerend Goed und dem australischen Ensemble The Border Project, versteht sich laut Ankündigungstext als "playful and immersive political exploration [...] thoroughly political, but never explicitly so. [...] By stripping their discourse of identifiable political messages, the show draws attention to the very reasons and motivations that compel voters to vote." (AUAWIRLEBEN 2015) Eine fingierte Spielshow, gegeneinander wetteifernde Kandidat_innen und ein per Knopfdruck abstimmendes Publikum geben dem Vorhaben den inhaltlichen Rahmen. Es entfaltet sich eine Spielhandlung, deren vermeintlich einziges Ziel es ist, dem einen Sieger oder der einen Siegerin die Stimmen der Publikumsmehrheit zu sichern. Wo der traditionelle theatrale Pakt, um den reibungslosen Ablauf einer Aufführung als ästhetisches Ereignis zu garantieren, die Trennung in agierende Schauspieler_innen und rezipierende Zuschauer_innen vorsieht, beginnt dieser Abend mit einem programmatischen Statement, das dem Publikum Partizipation verspricht.
Demokratie und Dramaturgie. Über den Zufall in Some use for your broken clay pots
Authors: Boesch Géraldine 
Published: March 2021

Der Schweizer Installations-, Video- und Performancekünstler Christophe Meierhans legt mit Some use for your broken clay pots (2013) einen Gegenentwurf zur gängigen Demokratiepraxis vor: Politiker_innen werden nicht wegen ihrer (Wahlkampf-) Versprechen gewählt, sondern können aufgrund ihrer Amtsführung jederzeit von den Bürger_innen abgesetzt werden. Es handelt sich bei diesem Prinzip der 'Disqualification' um eine Verkehrung der repräsentativen Demokratie, in der Politiker_innen für eine bestimmte Dauer aufgrund ihres Partei- oder Wahlprogrammes in ein Amt gewählt werden. Meierhans' System basiert auf einer Verfassung mit 350 Artikeln, die er während zwei Jahren gemeinsam mit einem Beratungsteam erarbeitet hat.

In der Lecture Performance Some use for your broken clay pots stellt der Schweizer Künstler Christophe Meierhans ein alternatives demokratisches System vor. Seiner Präsentation liegt eine ausgearbeitete Verfassung mit 350 Artikeln zugrunde. Meierhans fordert zur Diskussion seines politischen Entwurfs auf und das Publikum folgt seiner Einladung mit großer Dialogbereitschaft. Die schiere Anzahl der Wortmeldungen wie auch die detaillierte inhaltliche Auseinandersetzung der Zuschauer_innen mit Meierhans' Verfassung überrascht. Wie gelingt es der Performance, eine solch intensive und engagierte Beteiligung auszulösen? Meinen die Zuschauer_innen an einer politischen Debatte teilzunehmen, oder lassen sie sich auf ein (Theater-)Spiel ein? Wie wird diese ambivalente Situation etabliert und aufrechterhalten? Werden die Zuschauer_innen tatsächlich zu Agierenden, die Einfluss auf den Diskussionsverlauf nehmen, oder spielt Meierhans manipulativ mit ihren Wortmeldungen? Kurz: Wird hier der Theaterraum politisiert oder eine politische Diskussion ästhetisiert und parodiert?
Risks of cerebrovascular disorders associated with combined hormonal contraceptives
Authors: Novosartyan M. G. 
Published: March 2021

Introduction. Cerebral circulation disorders (CCD) hold the third place in the structure of complications coupled to combined oral contraceptives (СОСs). Acute disturbance of the cerebral blood supply is the main etiological factor for such complication; and hidden predisposition to thrombotic conditions such as thrombophilia plays a pivotal role in its pathogenesis, which is manifested due to administered hormonal contraceptives.Aim: to assess rate of detected genetic thrombophilic hemostatic defects, congenital and acquired ADAMTS-13 deficiency, antiphospholipid antibodies (APA), antibodies to phospholipid cofactors, hyperhomocysteinemia in patients with CCD administered with СОСs.Materials and Methods. A prospective analysis of 89 COCs use cases in women of reproductive age was carried out, among which 60 cases were selected for this study satisfying to the inclusion and exclusion criteria. Group I consisted of 30 patients manifested with various CCD types due to COCs use, group II – 30 women taking COCs for at least 1 year lacking any thrombotic complications.Results. Women administered with COCs are at the peak CCD risk within the first 2 months after the onset. Somatic diseases differed little in patients from groups I and II. In group I, 5 (41.7 %) patients with venous thrombosis did not have classical thrombophilia, but 4 (33.3 %) women had anti-ADAMTS-13 antibodies combined with elevated von Willebrand factor (vWF) level. Inherited thrombophilia was less prevalent in patients with arterial thrombosis and transient ischemic attack (TIA): 1 (5.5 %) case of Leiden factor V mutation compared to patients with venous blood flow disorders (p < 0.05). Such patients more frequently had criterial APA (61.1 %), so that 5 (27.8 %) patients were found to have more than one type of criterial APA. In 4 (22.2 %) cases these were patients with ischemic stroke, 3 (37.5 %) of which had combination of three criterial APA (triple positivity) and 1 (12.5 %) had two criterial APA (double positivity); among them detection rate of criterial APA was 50.0 %. One patient (double positivity) was with TIA.Conclusion. It was found that: i) genetic and acquired factors were identified at high rate in patients with CCD administered with COCs, contributing to coagulopathy (86.7 %); ii) in case of venous thrombotic CCD coupled to administered COCs, inherited thrombophilia (58.3 %) prevails, in arterial thrombosis – APA circulation (50.0 %); iii) etiopathogenetic role of APA circulation in impaired cerebral blood flow depends on antibody type (criterial APA) and titer; iv) preexisting hypercoagulability leading to CCD coupled to COCs may be linked to several thrombophilic defects unrelated to classical thrombophilia.

Abstract
In this article, we describe the infrastructure developed and managed by the Italian National Institute of Oceanography and Applied Geophysics – OGS for the seismological and geodetic monitoring of northeastern Italy. The infrastructure was constituted in response to the ML 6.4 Friuli destructive earthquake of 1976, with the main mandate of supporting civil protection emergency activities.
The OGS monitoring infrastructure is presently composed of a seismometric and a strong-motion network, complemented by a number of Global Navigation Satellite Systems stations, each delivering observational data in real time, which are collected and processed by the headquarters of the Center for Seismological Research of OGS in Udine. The OGS networks operate in close cooperation with Italian and international networks from neighboring countries, within the framework of the agreements for real-time data exchange, to obtain improved rapid earthquake location and magnitude estimations. Information regarding seismic events is released to the public through a dedicated web portal and, since 2013, through social media.
Aside from the standard monitoring activities (&gt;30,000 events have been recorded since 1976), the OGS has progressively increased the number of services to the public and to the Civil Protection of the Friuli Venezia Giulia and Veneto regions. The high availability of good quality data has resulted in the enhancement of scientific products, including advanced seismological studies of the area, spanning broadly from seismic source characterization to engineering seismology.
In the future, the OGS networks are expected to further contribute to the development of seismological research and monitoring infrastructures of the Central European region.
Dosimetric comparison of organs at risk with three-dimensional conformal radiation, intensity-modulated radiation and volumetric-modulated arc therapy in cervical cancer: a cross sectional study

Published: March 2021

Three-dimensional conformal radiation therapy (3DCRT), intensity-modulated radiation therapy (IMRT) and volumetric-modulated arc therapy (VMAT) are the three main radiotherapy treatment techniques for cervical cancer. Whether either technique significantly reduces the radiation exposure to organs at risk remains unclear. We dosimetrically compared the irradiated volumes of bone marrow, bladder and rectum in cervical cancer patients using 3DCRT, IMRT and VMAT techniques in those patients with FIGO stage IIIB cervical cancer, receiving chemo irradiation at our institute. A total of 10 patients were dosimetrically compared. Significant reduction in V10, V20, V30, V40, V50 Gy of bone marrow was observed with IMRT and VMAT when compared to 3DCRT. Similar results were seen with V20, V30, V40, V50 Gy of bladder, and V40, V50 Gy of rectum. While comparing IMRT and VMAT, statistically significant dose reduction was noted in V20 Gy of bone marrow and V20 and V30 Gy of bladder with VMAT. When compared with 3DCRT the use of IMRT and/or VMAT reduced the radiation exposure to bone marrow, bladder, and rectum volumes at various radiation dose levels. VMAT can further reduce the radiation exposure to bone marrow and bladder when compared with IMRT. Thus, we propose the use of VMAT in cervical cancer to reduce the OAR toxicities.
Sampah Adalah Berkah; Studi Pola Kehidupan Sosial Ekonomi Pemulung Di Sekitaran Tempat Pembuangan Ahir (TPA) Piyungan
Authors: Huzaemah Siti 
Published: March 2021

Penelitian ini hendak mengungkap bagaimana pola kehidupan sosial-ekonomi pemulung sampah di sekitaran tempat pembuangan ahir (TPA) di Piyungan dan apa yang menjadi faktor-faktor masyarakat memilih profesi menjadi pemulung sekalipun secara umum pemulung dianggap sebagai kelas sosial yang rendah. Metode yang digunakan dalam penelitian ini adalah metode penelitian kualitatif dengan pendekatan fenomenologis dengan mengunakan teknik pengumpulan observasi data wawancara. Teknik analisis data dengan tahapan sebagai berikut: menelaah seluruh data, mengkategorikan data, menghubungkan dengan landasan teori, dan menarik kesimpulan. Berdasarkan penelitian yang telah dilakukan dapat disimpulkan bahwa kondisi sosial ekonomi para pemulung di sekitaran TPA Piyungan secara keseluruhan dapat dikategorikan dalam taraf yang cukup baik, bahkan ada yang sampai pada taraf sangat baik, yakni tergolong sejahtera. Hal itu terlihat dari penghasilan sehari-harinya yang dapat dikatakan lumayan, juga dari pola hidupnya yang terbilang normal layaknya masyarakat lain, yakni mempunyai tempat tinggal yang layak berdinding tembok, beralas keramik. Selain itu mereka rata-rata mempunyai kendaraan peribadi seperti motor, bahkan beberapa ada yang mobil, mempunyai aset berupa sapi, rumah, dan kendaraan pribadi. Sekalipun tidak dapat dipungkiri, masih ada juga pemulung yang kurang baik dalam arti miskin.Sedangkan alasan para pemulung memilih profesi sebagai pemulung selain karena memulung merupakan pekerjaan yang menjanjikan hasilnya, juga karena tidak adanya pilihan lain selain menjadi pemulung. Hal itu disebabkan adanya kendala-kendala seperti, tidak memiliki keahlian kusus, terbatasnya lapangan pekerjaan, tidak mempunyai modal untuk membangun usaha, serta karena faktor pendidikan yang rendah.

Authors: Silva Josemar Pereira da , Vianna Neto Márcio Ribeiro , Almeida Gustavo Matheus , Oliveira Éder Domingues de 
Published: March 2021

A metodologia mais comum de obter os mapas de curvas residuais é através de um sistema de equações diferenciais, comumente resolvido em duas etapas, a saber, um equilíbrio líquido-vapor e um sistema de equações diferenciais. O objetivo deste trabalho é apresentar uma nova metodologia de elaboração dos mapas de curvas residuais. Nesta metodologia o bolha T é considerado uma equação diferencial e juntamente coma equação de Rayleigh, que é um sistema de equações diferenciais que determina a composição residual de uma mistura líquida a ser destilada, são resolvidas através do Método das Diferenças Finitas. Para este intuito a nova metodologia será aplicada aos sistemas ternários éter etílico/metanol/1-butanol e etanoll/2-metil 2-propanol/metilciclohexano. O coeficiente de fugacidade da fase de vapor foi calculado pela equação de Virial (truncada no segundo coeficiente), e o coeficiente de atividade da fase líquida, através dos modelos NRTL, UNIQUAC e UNIFAC. Os resultados mostraram o potencial da nova metodologia em comparação às abordagens convencionais

Published: March 2021

El principio de participación económica de los miembros de la cooperativa recoge los principios contemplados desde el origen del cooperativismo moderno de interés limitado al capital y reparto de los excedentes en función de la actividad cooperativizada realizada por los socios. Pero además afirma la contribución equitativa al capital de la cooperativa por parte de los socios y su gestión democrática, y deja abierta la necesidad de un capital fuerte y estable que pueda permitir el funcionamiento de la empresa a lo largo del tiempo, así como los problemas que son susceptibles de acompañarle.

Las personas jurídicas consumidoras. El caso de las cooperativas de consumidores y usuarios
Authors: Fernández Fernández Eugenia 
Published: March 2021

Las normas en materia de protección a los consumidores han experimentado una notable expansión desde los años setenta. Primigeniamente concebido como un conjunto de normas aplicables únicamente a las personas físicas, nuestro ordenamiento jurídico presenta una particularidad frente a otros de nuestro entorno y es la extensión del concepto de consumidor a las personas jurídicas. En el presente supuesto se pretende no tanto analizar el concepto de consumidor persona jurídica sino su aplicabilidad a un concreto tipo de persona jurídica como es la sociedad cooperativa y, particularmente, a la cooperativa de consumidores y usuarios con el propósito de arrojar luz sobre una cuestión que ha dado lugar a pronunciamientos judiciales dispares.

Uso indebido de la figura de la sociedad cooperativa
Authors: Díez Ácimas Luis Ángel 
Published: March 2021

El elevado número de sociedades cooperativas constituidas en los últimos años nos obliga a ser optimistas sobre la contribución de éstas al desarrollo social y al crecimiento económico y a pensar que en el futuro próximo seguiremos asistiendo al nacimiento de muchas empresas de esta naturaleza. Pero, la observación de la realidad empresarial, también, nos obliga a denunciar la existencia de sociedades cooperativas que optan por este revestimiento jurídico para obtener el régimen propio de éstas cuando su verdadera naturaleza dista mucho de los principios y características propias de las cooperativas. Por otro lado, se quiere destacar la necesidad de que la normativa sobre esta materia sea respetuosa con la esencia del modelo cooperativo y que las diferentes administraciones públicas con competencias sobre estas empresas realicen una adecuada labor de vigilancia para garantizar el respeto de estas a la legislación y a los principios cooperativos.
