Experimental investigation on precipitation damage during water alternating flue gas injection
Authors: Wang Zhouhua , Zhang Yuping , Liao Haoqi
Published: July 2020

Water Alternating Gas (WAG) approach can improve the efficiency of gas flooding. However, the precipitation damage that is induced by the gas injection may be inevitable. The precipitation pressure point test of gas injection, and the WAG parallel double-tube long-core flooding experiment under different injection conditions were systematically performed to obtain the optimum injection parameters. The variations of petrophysical properties were caused by precipitation, and its morphology was also determined by centrifugal capillary force and environmental scanning electron microscope. The precipitation pressure rised with the increase of the amount of gas injection, generally 2.0 MPa ~ 3.0 MPa higher than the bubble point pressure (Pb), and it was confirmed by X-ray energy spectrum and scanning electron microscope that the precipitation was mainly asphaltene. The optimum injection parameters for WAG were Gas–Water Ratio (GWR) of 1:1 and slug size of 0.1 HydroCarbon Pore Volume (HCPV), which benefited the recovery of low-permeability and high-permeability pipe by additional recovery of 28.5% and 17.4% respectively, while WAG process enhanced the total oil recovery by 23.4%. The pore volume and median radius of capillary pressure of all cores were both reduced with more obvious effects on conglomerate. Combined with the results of sediment saturation, it also showed the poorer the physical properties of the cores, the severer the influence of the precipitation. Overall, the WAG could greatly improve the recovery but the influence of precipitation must be considered.

Reinventing Hybridity in a Globalized Context: The Case of Turkish Soap Operas and Their Reception in Morocco
Authors: Rafi Ouafaa
Published: July 2020

This article aims to examine Turkish soap operas as a multi-faceted phenomenon that, as a product of cultural hybridization, will also contribute to similar cultural hybridization in the countries and regions where they are broadcasted. The purpose is to highlight the fact that this is not a unilateral process of cultural influence, with an active production pole and a static and non-active receptor, but rather a dialectical process of hybridization, transformation, and adaptation. Analyzing the power of television and the strategies used by soap operas to attract an audience, the article highlights the dynamics accompanying their diffusion and the impact on the watchers. The main conclusion of this work is that Turkish soap operas are at the same time an outcome of cultural hybridization and a vector of this phenomenon since the series will influence the cultural frame of references of their host societies. The case study on Morocco helps us understand the encompassing dynamics at stake when it comes to cultural influence and interaction.

Published: July 2020

FDA’s Center for Devices and Radiological Health (CDRH) is responsible for regulating firms who manufacture, repackage, relabel, and/or import medical devices sold in the United States. Regulatory control increases from class I to III. Most class I devices are exempt from Premarket Notification 510(k); most class II devices require pre-market notification 510(k); and most class III devices require Pre-market Approval.The Food and Drug Administration Modernization Act of 1997 (FDAMA) added the De Novo classification option as an alternate pathway to classify novel medical devices that had automatically been placed in class III after receiving a “not substantially equivalent” determination in response to a pre-market notification [510(k)] submission.Class III Devices are those considered as high risk along these lines requiring the regularly lengthier Pre-market approval (PMA) process. The new De Novo process was designed to usher through any new device that was both Unprecedented (novel) and Low to moderate risk (or with a risk that was easily mitigated). The most inventive gadgets are considered high-hazard due to the non-attendance of equivalent items and follow either the De Novo or PMA path. Truly high-risk devices, in which deficient data exists to decide if general and special controls are sufficient to give sensible attestation of the item’s safety and effectiveness, follow the PMA pathway. Novel devices that do not have a predicate are classified in the highest risk class,despite the level of genuine risk it postures or the capacity of general and special controls to guarantee safety and effectiveness. The De Novo process allows these novel devices with low to moderate risk to be reclassified from a high-risk class, which requires a PMA.

Authors: Kulyadi Girish Pai , Jaiswal Himani , Muddukrishna B. S.
Published: July 2020

Data integrity refers to data reliability throughout the data lifecycle. Terminology “ALCOA” means that the data should be attributable, legible, contemporaneously recorded, original, and accurate. “ALCOA Plus” was introduced later. Violation of the integrity of data is termed as a breach of data integrity. It can take place in various fields, but not limited to manufacturing, quality control (QC), quality assurance (QA), and research. Some of the reasons for breach in data integrity are fabrication or duplication of data, out of specification, out of trend, back-dating, manipulation of data, inadequate standard operating procedures (SOPs), common usernames, and shared passwords. A study to assess the impact of data integrity violations based on the US FDA warning letters was conducted. The majority of data integrity breaches belonged to QC. The frequency of letters based on the country has been presented in the form of a graph. China and India received the highest number of letters for breach of data integrity in the year 2018 and 2017 respectively. It can be concluded that it is important to enforce data integrity and develop strategies for the same. The study is beneficial to understand the reason, affected field of work and remediation methods for data integrity, and improve regulatory compliance.

Kurumsal yapı ülke ekonomilerinin makroekonomik performansları üzerinde önemli etkiler meydana getirmektedir. Kurumsal yapı göstergeleri oldukça farklı ve çok sayıdadır. Ekonomik özgürlükler bu göstergelerin biridir. Bu çalışmada kurumsal yapı göstergelerinden ekonomik özgürlükler ile ekonomik büyüme ilişkisi BRICS ülkelerinin 1995-2018 dönemi için panel eşbütünleşme testi ile analiz edilmiştir. Yatay kesit bağımlılığını dikkate alan ve çoklu yapısal kırılmaya olanak veren panel eşbütünleşme testi ile değişkenler arasındaki uzun dönem ilişkisi incelenmiştir. Yapılan analizde ekonomik büyümeyi temsilen kullanılan kişi başına düşen GSYİH miktarı bağımlı değişken ve kurumsal yapıyı temsilen kullanılan ekonomik özgürlükler endeksi ise bağımsız değişkendir. Çalışmanın analiz sonucuna göre ekonomik özgürlükler ile ekonomik büyüme arasında eşbütünleşme ilişkisi tespit edilmiştir. Eşbütünleşme ilişkisinin yönünün ve boyutunun ortaya konulabilmesi için katsayı tahmini yapılmıştır. Katsayı tahminine göre panel genelinde ekonomik özgürlüklerin ekonomik büyümeye etkisi negatif ancak istatistiksel olarak anlamsızdır. Bununla beraber, ekonomik özgürlükler ekonomik büyümeyi BRICS ülkelerinden Çin’de pozitif, Brezilya ve Hindistan’da negatif olarak etkilemektedir. Rusya ve Güney Afrika’da ise ekonomik özgürlüklerin ekonomik büyümeye etkisi istatistiksel olarak anlamsız bulunmuştur.
Enflasyon ile Finansal Gelişme İlişkisi: Yüksek ve Düşük Enflasyonlu Ülkeler Üzerine Ampirik Kanıtlar
Authors: TÜRKMEN Sena , AĞIR Hüseyin
Published: July 2020

Literatürde, finansal gelişmeyi etkilediği ileri sürülen çeşitli makroekonomik değişkenler tartışılmaktadır. Enflasyon bunlardan birisidir. Bir ekonomide yüksek enflasyon en başta belirsizliğe neden olarak genellikle istikrarsız bir makroekonomik ortam ile ilişkilendirilmektedir. Belirsizlik ortamında firmalar yeni yatırımlardan kaçınarak üretimin azalmasına neden olabilmekte ve reel sektörle finansal sektör arasındaki ilişkiye engel olabilmektedir. Dahası, belirsizlik ortamı finansal aracılığın maliyetini yükselterek finansal gelişme sürecini sekteye uğratabilmektedir. Diğer taraftan yüksek enflasyon, sabit gelirliler aleyhine gelir dağılımını bozarak tasarrufların erimesine de neden olmaktadır. Bu durum yatırımlar için gerekli olan fonların azalması süreciyle finansal sistemi olumsuz etkilemektedir. Dolayısıyla konu ile ilgili ampirik literatür enflasyondaki artışın finansal gelişmeyi negatif etkilediğini, enflasyondaki azalışın da finansal gelişmeyi pozitif etkilediğini ortaya koymaktadır.
Bu çalışmanın amacı, yüksek enflasyonun finansal piyasalar üzerindeki olumsuz etkilerinden hareketle, seçilmiş yüksek ve düşük enflasyonlu ülke grubu örnekleri için ayrı ayrı enflasyon ile finansal gelişme göstergeleri arasındaki ilişkiyi, kontrol değişkenleri de kullanarak yeni nesil panel ekonometrik yöntemlerle tahmin etmektir. Elde edilen bulgular, yüksek ve düşük enflasyonlu ülke gruplarında enflasyon değişkeninin finansal gelişmeyi temsil eden göstergeleri negatif etkilediğini ortaya koymaktadır.

Authors: DOĞAN Selen , OĞUZHAN Yavuz Sezer
Published: July 2020

Bu çalışmanın amacı; algılanan sosyal destek, personel güçlendirme, iş stresi ve kendilik algısı arasındaki ilişkilerinin ortaya konmasıdır.Söz konusu kavramların birbirleriyle olan ilişkileri Kayseri’de faaliyet gösteren özel bir hastanenin 431 çalışanıyla anket kullanılarak gerçekleştirilmiştir. Korelasyon ve hiyerarşik regresyon analizi yöntemi kullanılarak incelenen değişkenler arasındaki ilişkiler, önemli bulgulara ulaşılmasını sağlamıştır. Sosyal destek, personel güçlendirme, iş stresi ve kendilik algısı değişkenleri ile ilgili literatürde çeşitli çalışmalar görülmekle beraber, bu değişkenleri birlikte konu edinmiş bir çalışma göze çarpmamıştır. Gerçekleştirilen bu çalışma sayesinde literatürde var olan bu boşluğun dolduracağı düşünülmektedir. Elde edilen bulgular ışığında, sosyal desteğin alt boyutu olan iş arkadaşı desteğinin personel güçlendirme alt boyutlarından “anlam”a olumlu, yetkinliğe etkisinde ise olumsuz kendilik algısının düzenleyici rolü olduğu anlaşılmıştır. Bununla birlikte, sosyal desteğin alt boyutu olan örgüt desteğinin iş stresi alt boyutları stres ve baş etmeye etkisinde olumsuz kendilik algısının düzenleyici rolü olduğu saptanmıştır.
Bu çalışma, çalışanların psikolojik olarak güçlendirilmelerinde ve iş yerinde yaşadıkları stresi azaltmada sosyal desteğin önemli olduğunu ve kendilik algılarının ise bu ilişkiyi artırmada düzenleyici etkin bir rol üstleneceği hususunda katkı sunmaktadır. Bu çalışmanın uygulayıcılar ve araştırmacılara yön vereceği düşünülmektedir.
DABN Borazabicycles: Formation from MIDA Boronates and Synthetic Utility
Authors: Kaldas Sherif James , tien chieh-hung , dos Passos Gomes Gabriel , Meyer Stephanie , sirvinskas martynas , Foy Hayden , Dudding Travis , Yudin Andrei
Published: July 2020

We report that coordinative hemilability allows the MIDA amine to behave as a nucleophile to intercept π-allyl intermediates. A mechanistic investigation indicates that this rearrangement proceeds through an SN2-like displacement at tetrasubstituted boron to furnish novel DABN (2,8- dioxa-5-aza-1-borabicyclo[3.3.1]nonane-3,7-dione) boronates. Oxidative addition into the N-C bond of the DABN scaffold reverses the reaction and furnishes borylated π-allyl intermediates that can then be trapped with complete linear selectivity. DFT calculations indicate that stabilizing interactions in the transition state, as well as the steric bulk of the MIDA unit, are the origins of the excellent regioselectivity. We further demonstrate the utility of our new reagents by way of a 3-component coupling that features allylammonium DABN boronates as linchpin reagents. This report disseminates a previously unknown aspect of MIDA boronates that can now be exploited.

Published: July 2020

Mesoporous Ga-silicates were efficiently prepared using a sustainable and continuous synthesis procedure. Three different Si/Ga ratios of 34, 74 and 148. The insertion of Ga predominantly as single site in tetrahedral coordination in the silica framework was elucidated by XPS, using the Auger parameter of Ga in a Wagner plot representation. The speciation of Ga was further clarified using solid state 71Ga NMR spectroscopy, confirming the formation of mainly isolated Ga species. Consistently, the aerosol-made Ga-silicates displayed outstanding turnover frequencies (up to 677 h-1) and selectivity, markedly outcompeting other reference metallosilicate catalysts reported in literature. Moreover, the most active catalyst was successfully reused in multiple catalytic cycles thus proving its stability under the selected reaction conditions.
Swarm-CG: Automatic Parametrization of Bonded Termsin Coarse-Grained Models of Simple to Complex Molecules via Fuzzy Self-Tuning Particle Swarm Optimization
Authors: Empereur-mot Charly , Pesce Luca , Bochicchio Davide , Perego Claudio , Pavan Giovanni M.
Published: July 2020

We present Swarm-CG, a versatile software for the automatic parametrization of bonded parameters in

coarse-grained (CG) models. By coupling state-of-the-art metaheuristics to Boltzmann inversion, Swarm-

CG performs accurate parametrization of bonded terms in CG models composed of up to 200 pseudoatoms

within 4h-24h on standard desktop machines, using an AA trajectory as reference and default

settings of the software. The software benefits from a user-friendly interface and two different usage

modes (default and advanced). We particularly expect Swarm-CG to support and facilitate the

development of new CG models for the study of molecular systems interesting for bio- and nanotechnology.

Excellent performances are demonstrated using a benchmark of 9 molecules of diverse

nature, structural complexity and size. Swarm-CG usage is ideal in combination with popular CG force

fields, such as e.g. MARTINI. However, we anticipate that in principle its versatility makes it well suited for

the optimization of models built based also on other CG schemes. Swarm-CG is available with all its

dependencies via the Python Package Index (PIP package: swarm-cg). Tutorials and demonstration data

are available at: www.github.com/GMPavanLab/SwarmCG.
Isogonal Weavings on the Sphere: Knots, Links, Polycatenanes
Authors: O'Keeffe Michael , Treacy Michael
Published: July 2020

We describe mathematical knots and links as piecewise linear – straight, non-intersecting sticks meeting at corners. Isogonal structures have all corners related by symmetry ("vertex" transitive). Corner- and stick-transitive structures are termed regular. We find no regular knots. Regular links are cubic or icosahedral and a complete account of these is given, including optimal (thickest-stick) embeddings. Stick 2-transitive isogonal structures are again cubic and icosahedral and also encompass the infinite family of torus knots and links. The major types of these structures are identified and reported with optimal embeddings. We note the relevance of this work to materials- and bio-chemistry.
Daphnia magna tolerance to toxic cyanobacteria in the presence of an opportunistic infection within an evolutionary perspective
Authors: Boudry Alice , Devliegere Sarah , Houwenhuyse Shira , Clarysse Lucas , Macke Emilie , Vanoverberghe Isabel , Decaestecker Ellen
Published: July 2020

In aquatic environments, interactions between cyanobacteria and their grazers are crucial for ecosystem functioning. Cyanobacteria are photosynthetic prokaryotes, which are able to produce large blooms and associated toxins, some of which are able to suppress grazer fitness. Cyanobacterial blooms are intensified by global warming and eutrophication. In our experiments, the tolerance of Daphnia magna (Straus, 1820), an efficient grazer of toxic cyanobacteria, was studied. We used different D. magna clones sampled from different sediment depths, which corresponded to different time periods of eutrophication. Our results showed that different clones had a different tolerance towards the toxic cyanobacterial species, Microcystis aeruginosa, confirming the presence of genetic variation in D. magna tolerance to cyanobacteria. However, there was not a significant adaptive effect of sediment depth. As expected, in general under controlled, infection-free conditions M. aeruginosa reduced D. magna survival. However, a coincidental, non-intended opportunistic fungal infection in a first experiment allowed us to compare the response of D. magna to M. aeruginosa in infected individuals and non-infected individuals (from a second experiment). In the presence of this opportunistic infection, there was no negative effect of M. aeruginosa in the D. magna clones, suggesting that exposure to the infection provided protection for Daphnia individuals towards Microcystis. Biotic interactions can thus be important in the interpretation of cyanobacterial effects in zooplankton grazers and in finding appropriate solutions to reduce the occurrence of cyanobacterial blooms.
The Effect of the 2017 Tax Reform on Investment
Authors: Occhino Filippo
Published: July 2020

The 2017 tax reform affected investment through many channels. I use a macroeconomic model to estimate the overall effect. That estimate suggests that, because the different provisions worked in different directions, the initial impact of the tax reform on investment was small. The same model predicts that the tax reform will hold investment down in the medium term.

Este artículo propone incorporar el enfoque de la calidad democrática para el análisis de dichas políticas. Cuánto pesan los aspectos democráticos en comparación con otros factores de poder dentro del régimen político ha sido una de las preguntas que guían esta propuesta. El artículo invita a repensar las políticas de comunicación incorporando nociones e informes de la calidad democrática con la idea de avanzar en instituciones confiables para el sector de la comunicación. Para eso se exponen conceptos claves para entender qué significa la calidad democrática, cómo puede ser medida a través de indicadores y cómo incorporar a las políticas de comunicación en dicho esquema. A su vez, el trabajo revisa estándares de la regulación de la convergencia digital como la libertad de expresión en Internet, la neutralidad de la red y el acceso a la información y los pone en relación con el objetivo mencionado. Esta propuesta se desprende de una investigación en curso para el nivel de doctorado que analiza la regulación de la convergencia digital durante el kirchnerismo (2003-2015) con especial atención en el estudio de Argentina Digital Ley 27.078.

Mind the gap: testing the Rayleigh hypothesis in T-matrix calculations with adjacent spheroids
Authors: Schebarchov D , Le Ru EC , Grand Johan , Auguié B
Published: July 2020

The T-matrix framework offers accurate and efficient modelling of electromagnetic scattering by nonspherical particles in a wide variety of applications ranging from nano-optics to atmospheric science. Its analytical setting, in contrast to purely numerical methods, also provides a fertile ground for further theoretical developments. Perhaps the main purported limitation of the method, when extended to systems of multiple particles, is the often-stated requirement that the smallest circumscribed spheres of neighbouring scatterers not overlap. We consider here such a scenario with two adjacent spheroids whose aspect ratio we vary to control the overlap of the smallest circumscribed spheres, and compute far-field cross-sections and near-field intensities using the superposition T-matrix method. The results correctly converge far beyond the no-overlap condition, and although numerical instabilities appear for the most extreme cases of overlap, requiring high multipole orders, convergence can still be obtained by switching to quadruple precision. Local fields converge wherever the Rayleigh hypothesis is valid for each single scatterer and, remarkably, even in parts of the overlap region. Our results are validated against finite-element calculations, and the agreement demonstrates that the superposition T-matrix method is more robust and broadly applicable than generally assumed.
Caracterización clínica, imagenológica y quirúrgica de la discopexia en pacientes con artropatía discal de la art iculación temporomandibular. Estudio de serie de casos
Authors: Contreras-Delgado Carlos , Hernández-Andara Adalsa , Ortega-Pertuz Ana I
Published: July 2020

Introducción: El desplazamiento discal es la artropatía temporomandibular más común. Los desplazamientos discales sin Reducción (DDSR) constituyen una condición clínica en la cual en boca cerrada el disco articular se encuentra desplazado completamente, sin contacto con la vertiente anterior de la cabeza mandibular y en boca abierta el disco no es recapturado. El tratamiento quirúrgico realizado es la discopexia. A pesar de toda la información presente en la bibliografía aún existe controversia entre la elección de tratamiento del DDSR. Objetivo: Presentar la experiencia clínica, quirúrgica e imagenológica de la discopexia en DDSR mediante la presentación de una serie de casos. Metodología: Se realizó un estudio retrospectivo de las historias clínicas del Servicio de Cirugía Bucal y Maxilofacial del hospital General del Oeste “Dr. José Gregorio Hernández”, Distrito Capital, Venezuela, entre 2014-2018; se seleccionaron seis casos clínicos que presentaban DDSR, los cuales fueron intervenidos con discopexia, posteriormente se evaluaron clínica e imagenológicamente. Resultados: Los seis casos presentaron particularidades en el transcurso del tratamiento desde la fase inicial y en la postoperatoria. Se evidenció una franca mejoría en las manifestaciones clínicas, en contraste, la resonancia magnética postoperatoria, el cual reveló el desplazamiento discal nuevamente. Conclusiones: La estabilidad en la reubicación discal postoperatoria depende de múltiples factores, tales como la estabilidad oclusal, muscular y presencia de hábitos parafuncionales. El aumento en la apertura bucal fue la característica común en todos los pacientes de este estudio así como la disminución de la sintomatología dolorosa.

Tujuan penelitian ini adalah untuk mengetahui proses pembelajaran dan hasil karya gambar bentuk siswa  kelas IV SD Inpres Paccerakkang. Jenis penelitian ini adalah survei dengan analisis deskriptif  kualitatif. Sampel penelitian ini adalah guru dan siswa, yakni 1 orang guru kelas dan 33 orang siswa kelas IV C. Teknik pengumpulan data yang digunakan adalah observasi, wawancara, dan dokumentasi. Hasil penelitian menunjukkan bahwa penyusunan RPP, ketetapan unsur atau komponen RPP dapat dikategorikan sudah baik karena sudah tercantum pada RPP, dari segi penulisannya RPP ketepatan kata pada penulisan dan kerangka RPP sudah sesuai dengan standar proses pendidikan dasar dan menengah dengan RPP yang dibuat oleh guru, dapat diketahui bahwa pelaksanaan kegiatan pembelajaran SBDP di SD Inpres Paccerakkang sudah baik. Hal ini juga terlihat dalam setiap indikator, dimana guru telah melakukan pembelajaran sesuai tahapan pembelajaran dengan baik. Hal tersebut sesuai dengan pernyataan bahwa kegiatan belajar berhubungan dengan kegiatan siswa dalam mempelajari bahan yang disampaikan guru. Sedangkan kegiatan mengajar berhubungan dengan cara guru menjelaskan bahan kepada siswa. Dari hasil observasi dapat disimpulkan cara guru menilai pembelajaran tematik, yakni penilaian di kelas mengikuti aturan penilaian mata pelajaran lain di sekolah dasar. Mengingat bahwa kemampuan menggambar siswa kelas IV C belum semuanya baik, maka cara penilaian tidak ditekankan pada penilaian secara tertulis, kemampuan menggambar bentuk memiliki beberapa aspek yaitu, kesuaian objek, komposisi, teknik, dan kerapian merupakan kemampuan yang harus dikuasai oleh siswa dalam menggambar bentuk. Penguasaan terhadap keempat aspek  kemampuan tersebut adalah persyarat untuk mendapatkan hasil karya dan nilai baik dalam menggambar bentuk, penilaian dilakukan dengan mengacu pada indikator dari masing-masing kompetensi dasar hasil  belajar dari mata pelajaran, penilaian dilakukan secara terus-menerus selama proses belajar mengajar berlangsung.

Faculty Perceptions of Research Assessment at Virginia Tech
Authors: Miles Rachel , Pannabecker Virginia , Kuypers Jim A.
Published: July 2020

In the spring of 2019, survey research was conducted at Virginia Polytechnic Institute and State University (Virginia Tech), a large, public, Carnegie-classified R1 institution in southwest Virginia, to determine faculty perceptions of research assessment as well as how and why they use researcher profiles and research impact indicators. The Faculty Senate Research Assessment Committee (FSRAC) reported the quantitative and qualitative results to the Virginia Tech Board of Visitors to demonstrate the need for systemic, political, and cultural change regarding how faculty are evaluated and rewarded at the university for their research and creative projects. The survey research and subsequent report started a gradual process to move the university to a more responsible, holistic, and inclusive research assessment environment. Key results from the survey, completed by close to 500 faculty from across the university, include: a.) the most frequently used researcher profile systems and the primary ways they are used (e.g., profiles are used most frequently for showcasing work, with results indicating that faculty prefer to use a combination of systems for this purpose); b.) the primary reasons faculty use certain research impact indicators (e.g., number of publications is frequently used but much more likely to be used for institutional reasons than personal or professional reasons); c.) faculty feel that research assessment is most fair at the department level and least fair at the university level; and d.) faculty do not feel positively towards their research being assessed for the allocation of university funding.
