Nöroteolojik Açıdan Kesb Nazariyesi (Benjamin Libet Deneyi Çerçevesinde)
Authors: CAN Seyithan , KILIÇ Sabahaddin
Published: December 2019

Din-bilim ilişkisi tarihsel süreçte olduğu gibi günümüzde de tartışılmaya devam etmektedir. Hristiyan Avrupa’sında ortaya çıkan tartışmaların İslam dünyasını da etkilediği bir vakıadır. İslam kelamcıları, İslam dini ile bilim arasında bir çatışmanın olmadığı genel kabulüyle hareket ederler. Özellikle bu noktada kelamın vesâil alanı, metafiziğin desteklendiği alan olarak kabul görmektedir. Modern dönemde vesâil alanında önemli bilimsel çalışmaların olduğu görülmektedir bunlardan biri de Nöroteolojidir. Nöroteoloji,  davranışı nöral (sinirsel) temelde inceleyip açıklamaya çalışan bilim dalıdır. Bu noktada özellikle dindarlığın nörolojik temelleri ve evrimsel işlevi hakkında önemli bilgiler sunmaktadır.        Bu çalışmada kelamın en önemli tartışma konularından biri olan kesb nazariyesi, Nöroteolojik açıdan Benjamin libet deneyiyle değerlendirilmektedir. Deney sonuçları yayınlandığında o güne kadar felsefe ve bilim dünyasında tartışılagelen insanın irade özgürlüğü meselesine yeni bir tartışma zemini hazırlamıştır. Özellikle Eş’ârî’nin kesb anlayışının da ciddi tartışmalara sebebiyet verdiği bilinmektedir. Allah’ın mutlaklığı açısından ele alınan bu düşünce, insan özgürlüğü ve sorumluluğunu ortadan kaldırır düşüncesiyle eleştirilmiştir. Ancak Benjamin libet deneyinin, Eş’ârî’nin kesb anlayışına uygun veriler içermesi dikkat çeken bir husus olarak göze çarpmaktadır.
Heparin- and Zn2+-binding proteins from boar seminal plasma.
Authors: Hołody D , Strzezek J
Published: December 2019

Low molecular mass, heparin-binding proteins from seminal plasma play an important role in gametes interaction whereas plasmatic Zn2+-binding proteins stabilize chromatin and plasmalemma structures and protect spermatozoa in the female reproductive tract. By means of affinity chromatography the heparin- and Zn2+-binding proteins were isolated from boar seminal plasma and both preparations were analyzed by reverse HPLC. Most of the proteins bound to heparine and Zn2+-ions were classified as spermadhesins. Three fractions binding exclusively Zn2+ were isolated. They differ in amino-acid composition, content of glucosamine and content of protein components revealed by SDS/PAGE.

Authors: Arciuch L P , Bielecki D , Borzym M , Południewski G , Arciszewki K , Rózański A , Zwierz K
Published: December 2019

The activity of N-acetyl-beta-hexosaminidase was found to be significantly higher in the placentas collected after delivery from women in puerperium with symptoms of prolonged pregnancy or complicated by EPH gestosis, than in placentas from normal pregnancy. Isoelectrofocusing of placenta homogenates showed the presence of isoenzymes A, P and B of N-acetyl-beta-hexosaminidase. Different isoenzyme A patterns in homogenates were observed in placentas obtained from normal and prolonged pregnancies and in those complicated by EPH gestosis.
Hexahistidine (His6)-tag dependent protein dimerization: a cautionary tale.
Authors: Wu J , Filutowicz M
Published: December 2019

Nickel nitrilotriacetic acid (Ni2+-NTA) immobilization of hexahistidine (His6) tagged proteins has become one of the most commonly used methods of affinity chromatography. Perhaps the greatest utility of this protein purification method stems from the general belief that His-tagged proteins (comprised of His6) are little affected in their activities or efficiencies, while alterations in specificity are unexpected. Although this is certainly true in many instances, we present a case in which the biochemical properties of proteins being studied were fundamentally altered due to the presence of His-tags. We carried out these studies using variants of the pi(30.5) protein of plasmid R6K, a DNA binding protein which negatively regulates plasmid replication. Pi(30.5) can bind DNA containing a target sequence (TGAGR) arranged either asymmetrically (direct repeats) in the gamma origin, or symmetrically in inverted half-repeats (IR's) in the operator of its own gene, pir. Importantly, dimers of pi protein bind to an IR; this property allows researchers to quickly assess whether different regulatory variants of pi proteins exhibit altered dimerization properties. For example, pi(30.5) containing a single amino-acid substitution, F107S (pi200(30.5)), has been shown to be monomeric in solution and dimers were not observed bound to IR's. Here we demonstrate that the presence of a His-tag partially restores the ability of pi200(30.5) to dimerize in solution and bind to an IR in dimeric form. This report sends an important message that (other) proteins containing His-tags may differ from their wild type counterparts in dimerization/oligomerization properties.
Molecular modelling, synthesis and antitumour activity of carbocyclic analogues of netropsin and distamycin--new carriers of alkylating elements.
Authors: Bartulewic D , Markowska A , Wołczyński S , Dabrowska M , Rózański A
Published: December 2019

A series of netropsin and distamycin analogues was synthesised and investigated by molecular modelling. The lowest-energy conformations of four carbocyclic lexitropsins, potential carriers of alkylating elements, were obtained using the HyperChem 4.0 program, and compared with the DNA-lexitropsin crystal structures from the Brookhaven National Laboratory Protein Data Bank. A method for synthesis of carbocyclic lexitropsins was elaborated, with the use of a nitro group or azobenzene as precursors for the aromatic amino group. The influence of methoxy group in ortho position with respect to amide groups on the activity of the new compounds was investigated. All of the compounds tested showed high antitumour activity in the standard cell line of mammalian tumour MCF-7.
The intercalation of imidazoacridinones into DNA induces conformational changes in their side chain.
Authors: Mazerski J , Muchewicz K
Published: December 2019

Imidazoacridinones (IAs) are a new group of highly active antitumor compounds. The intercalation of the IA molecule into DNA is the preliminary step in the mode of action of these compounds. There are no experimental data about the structure of an intercalation complex formed by imidazoacridinones. Therefore the design of new potentially better compounds of this group should employ the molecular modelling techniques. The results of molecular dynamics simulations performed for four IA analogues are presented. Each of the compounds was studied in two systems: i) in water, and ii) in the intercalation complex with dodecamer duplex d(GCGCGCGCGCGC)2. Significant differences in the conformation of the side chain in the two environments were observed for all studied IAs. These changes were induced by electrostatic as well as van der Waals interactions between the intercalator and DNA. Moreover, the results showed that the geometry of the intercalation complex depends on: i) the chemical constitution of the side chain, and ii) the substituent in position 8 of the ring system.
Effect of ethanol on structural transitions of DNA and polyphosphates under Ca2+ ions action in mixed solutions.
Authors: Hackl E V , Blagoi Y P
Published: December 2019

In the present work using the IR spectroscopy method the effect of ethanol on structural transitions of DNA and polyphosphates under the action of Ca2+ ions in mixed solutions containing ethanol (0-25 vol.%) was studied. It was shown that, on its interaction with Ca2+ ions, in aqueous and mixed solutions DNA becomes transformed into compact form. With the increase of concentration of ethanol the degree of Ca2+-induced DNA compactisation rises. It was found that, in mixed solutions containing ethanol, Ca2+-induced DNA compactisation depends not only on the solution's dielectric permeability but also on the solution structure. On stabilisation of the water structure in the presence of low ethanol concentrations a stabilisation of the DNA macromolecule occurs that leads to the increase of the Ca2+ ion concentration necessary for DNA compactisation. Comparison of the effects of ethanol on Ca2+-induced structural transitions in DNA and polyphosphates in mixed solvents permits to suppose that at alcohol concentrations in solution resulting in disruption of the water spatial structure, some peculiarities are observed in the behavior of those molecules whose hydrophobic interactions are essential.
ULAMA-DIFABEL: MENARASIKAN EKSPRESI KULTURAL MASYARAKAT BANJAR DALAM LENSA STUDI DISABILITAS
Authors: Amin Barkatullah
Published: December 2019

Ulama in Banjar society take place as religious elite whose roles are very important. They used to be treated specially in practice, like being honored and respected. However, what if there is Ulama who is physically and mentally different (difabel). Do people treat differently? How do people then perceive it? This paper aims to see how the attitudes and views of people in the Banjar community towards the “Ulama-Difabel” – Islamic scholars with disabilities who participate in religious and community activities. This is a qualitative research with ethnography approach. It uses social model of disability theory. the results of this study explain that although the government has ratified the Law of the Republic of Indonesia No. 19 of 2011 concerning the Ratification of the CRPD, however, it cannot be called as the sole reason for the establishment of an inclusive paradigm that develops in society in a dominant way. In spite of that, the Banjar people interpret the existence of diffable scholars as a transcendent phenomenon because of the normative influence, metaphysical, and theological (Islam Banjar) views which both encourage each other to form social constructs with a paradigm of the Social Model of Disability in Banjar society. This phenomenon is also affected by some factors like people’s understanding toward diffabled condition, culture, education, and religious doctrine accepted. Ulama dalam masyarakat Banjar menempati posisi sebagai elit keagamaan yang perannya sangat penting. Sehingga pada praktiknya ulama sering mendapatkan perlakuan spesial, seperti dimuliakan dan dihormati. Namun, bagaimana jika ada ulama yang memiliki perbedaan pada fisik ataupun mentalnya (difabel), apakah perlakuan masyarakat menjadi berbeda? Bagaimana kemudian masyarakat mempersepsikannya? Paper ini bertujuan untuk melihat bagaimana sikap dan pandangan masyarakat Banjar terhadap Ulama-Difabel yang turut serta dalam kegiatan keagamaan maupun kemasyarakatan. Kajian ini bersifat kualitatif dengan pendekatan etnografi. Pisau analisisnya menggunakan teori Social Model of Disability. Hasil kajian ini menunjukkan bahwa meskipun pemerintah telah meratifikasi Undang-Undang Negara Republik Indonesia Nomor 19 Tahun 2011 tentang Pengesahan CRPD, tetapi hal itu tidak bisa disebut sebagai satu-satunya alasan terbentuknya paradigma inklusif yang berkembang dalam masyarakat, yang  kemudian mempengaruhi cara pandang masyarakat secara dominan, tetapi lebih dari itu, masyarakat Banjar memaknai keberadaan Ulama-Difabel sebagai fenomena transenden, karena dipengaruhi oleh pandangan-pandangan normatif, metafisik dan teologis (Islam Banjar) yang kemudian keduanya saling mendorong terbangunnya konstruksi sosial berparadigma Social Model of Disability pada masyarakat Banjar. Fenomena ini juga dipengaruhi oleh faktor-faktor seperti; pemahaman masyarakat terhadap kondisi difabel itu sendiri, budaya, pendidikan, dan doktrin keagamaan yang diterima.

Foreign language teacher education in Germany, Iran and Poland – a comparative study
Authors: Gębal Przemysław E. , Nawracka Monika J.
Published: December 2019

This article discusses the issues of academic education of foreign language teachers in three different educational systems. It presents them in the context of education culture and school culture, showing their influence on the way of organization and realization of education processes.

School and education in general, including university preparation for the teaching profession is a place of developing so-called social capital. Reflection on the way these processes operate plays a key role in the planning and implementation of effective educational activities, using the so-called good practices of each of the systems.

In the comparative research, the teacher training programmes in Iran, Germany and Poland are subject to comparative analysis against the framework of European standards for teacher education.
Social media in foreign language teaching and learning – a review
Authors: Tsai Natalia
Published: December 2019

The main purpose of this review is to present why and how social media can be applied in language teaching and learning, as seen from the point of view of practitioners. Vygotskian constructionism has provided the theoretical framework for the investigation. The wide availability of social media and their high penetration rate are seen as key advantages. The stress has been put on the fact that such platforms enable users to interact with others and acquire the target language in their own community of practice. The learning process, thus, gets enriched by both individual and collaborative dimensions. Negotiation of meaning, as well as the autonomy in creating one’s new identity and customizing the study content, become crucial aspects of the experience. Assuming accountability for one’s own learning results in increased intrinsic motivation to bridge the gap between the current level of knowledge and the desired proficiency level. Finally, certain features of social media that allow instructors to use them in class are discussed.
Inflection in a bilingual child. A case study
Authors: Wtorkowska Maria
Published: December 2019

In the article, the author presents the mutual impacts of Polish and Slovenian on one another in terms of nominal inflection (mainly of nouns and adjectives) and verb inflection in the speech of a bilingual child in his early development, specifically: positive transfer and interferences. She discusses the parallel children’s bilingualism of a boy living in a mixed family, where various strategies of addressing the child were used, mainly the rule “one parent, one language” (mother – Polish, father – Slovenian). The presence of interference in the child’s speech also caused by the language of the environment in which the boy lived, i.e. the Slovenian language, which could become the dominant one. Some of the examples of Marko’s speech presented in the article indicate special linguistic phenomena which existed in his early linguistic development, e.g., code mixing, switching from one language to the other, and translation.
What do we call the children? Familial terms of address in Polish and English
Authors: Dziwirek Katarzyna
Published: December 2019

The paper addresses cultural differences between Polish and English as they pertain to familial terms of address. Using corpus data, I demonstrate that Polish parents frequently address their children using hypocoristic forms of the terms syn ‘son’, córka ‘daughter’ and dziecko ‘child’. These forms convey affection and emphasize familial ties. English parents, on the other hand, use children’s names, nicknames, or terms of endearment. I argue that these differences follow from underlying contrasts in cultural scripts: English individualism and Polish warmth.
From Japanese Schulz to Polish Parnicki – around the year 1974
Authors: Sekiguchi Tokimasa
Published: December 2019

The major works by Bruno Schulz and Witold Gombrowicz were translated into Japanese in the 1960s, mainly by Yukio Kudō. I was enchanted by those Japanese texts to such an extent that I decided to abandon French literature and switch to Polish contemporary literature. In 1974, I came to Poland on a post-graduate fellowship of the Polish government, and I began studies in literature and the Polish language at the Jagiellonian University. During that two-year stay in Krakow, my view of Polish literature changed several times. The phase well established in the Japanese translations I had known ended quickly. Then I began to “hunt” for promising Polish authors not yet present in world literature. I thus discovered the prolific, esoteric and difficult Teodor Parnicki (1908–1988). This essay is my description of my “penetrating” the world of the Polish language at that time.

Authors: Peixoto Azeredo Felipe Francisco , Franco Xavier José Roberto , Franco Xavier José Roberto
Published: December 2019

A atual lei de drogas estipulou critérios para a diferenciação entre os crimes de uso e tráfico de drogas, estabelecendo diferentes modelos de resposta estatal para esses dois crimes. Esta pesquisa debruça-se sobre sentenças que versam sobre o crime de tráfico de drogas para entender como os juízes diferenciam os crimes de uso e tráfico. A partir da análise de uma amostra de todas decisões de primeira instância do Tribunal de Justiça do Estado do Rio de Janeiro do ano de 2015, pudemos estabelecer uma série de categorias pelas quais os magistrados justificam a sua decisão em matéria de tráfico de drogas. Trata-se aqui de uma pesquisa empírica de cunho qualitativo, que contou com a técnica de análise de documentos como base. A análise foi realizada lançando-se mão da teorização fundamentada nos dados (TFD) e os resultados apontam, em conformidade com a literatura da área, para a centralidade da prova testemunhal na distinção entre usuários e traficantes.

OPTIMALISASI TITIK DIDIH MINYAK GORENG PADA SUHU TINGGI DENGAN METODE PERANGKAP SUHU
Authors: Arizona Kurniawan , Nurhuda Nurhuda , Saroja Gancang
Published: December 2019

Konversi biomassa dengan metode pirolisis membutuhkan suhu yang tinggi sekitar 200-500oC tergantung dari jenisnya. Untuk mencapai suhu tersebut dibutuhkan tekanan eksternal yang mengakibatkan proses konversi tidak efesien. Diusulkan suatu skema baru yaitu reaktor pemanas menggunakan metode perangkap suhu tanpa memberikan tekanan eksternal. Pengujian telah dilakukan dengan cara memanaskan 4liter minyak goreng pada kecepatan putaran pengaduk yang bervariasi yaitu 5 rpm, 10 rpm, 20 rpm dan 30 rpm. Hasil yang diperoleh, makin cepat putaran pengaduk, mengakibatkan kenaikan suhu makin lambat. Suhu maksimum yang dicapai pada reaktor bawah yaitu 300oC dengan kecepatan putaran pengaduk 5 rpm. Diharapkan dengan pencapaian suhu ini, reaksi konversi biomassa dengan metode pirolisis untuk penelitian selanjutnya dapat tercapai.
POTENSI KEPING DVD BEKAS SEBAGAI PANEL SURYA ALTERNATIF
Authors: Auliya Helmi , Widyowati Ninik , Haqiqi Arghob Khofya
Published: December 2019

Penulisan ilmiah ini memberikan gambaran menjelaskan mengenai penggalian potensi keping DVD (Digital Versatile Disc) yang sudah tidak terpakai sebagai alternatif panel surya pada umumnya (monocrystalline). Penulisan ilmiah ini dilakukan berdasarkan latar belakang masalah yang terjadi terkait belum meratanya fasilitas listrik di daerah-daerah tertinggal. Sehingga pemanfaatan tenaga surya dirasa menjadi solusi dalam mengatasi masalah tersebut. Namun dengan kendala masih mahalnya panel surya sebagai alat konversi energi matahari menjadi listrik yang masih mahal maka penggunaan keping DVD bekas diharapkan bisa menjadi solusi alternatif pengganti panel surya. Penulisan ilmiah ini dilakukan dengan cara membuktikan secara langsung yaitu dengan metode eksperimen yang berdasarkan kajian pada studi pustaka, praktik langsung dan berbasis produk. Dari kajian studi pustaka diketahui bahwa keping DVD bekas mempunyai potensi untuk dikembangkan menjadi pengganti fungsi panel surya. Tidak hanya itu, untuk memperkuat penelitian ini kami juga melakukan ekperimen guna mengetahui kebenaran mengenai keping DVD bekas yang akan dijadikan menjadi prototype yang difungsikan hampir sama dengan panel surya.

Berdasarkan hasil penelitian, kami membuktikan bahwa keping DVD bekas masih mempunyai manfaat yang besar jika dimanfaatkan secara efektif dan efisien. Selain itu kami juga memperoleh gambaran bahwa menggunakan keping DVD bekas, perangkat panel surya menjadi lebih ekonomis dan dapat dikembangkan lagi mengingat energi yang dihasilkan kepingan DVD ini masih dapat menghasilkan energi listrik yang lebih besar lagi.
Meta Konsep Kekuasaan dan Demokrasi Dalam Kajian Teori Politik
Authors: Triantini Zusiana Elly
Published: December 2019

Tulisan ini akan mengupas tentang bagaimana konsep kekuasaan dikaji oleh para pemikir seperti; Foucault, Mills, Duhl, namun juga tidak kalah menarik tulisan ini ingin menyajikan sedikit perbandingan dengan pemikiran politik Islam Ibnu Kholdun dan AL Mawardi yang juga mendeskripsikan konsep politik dan power dengan rujukan term teologis. Menjadi penting memahami konsep kekuasaan dari dua belahan peradaban dunia tersebut, apalagi dalam konteks melihat politik di Indonesia. Mengapa demikian? Karena Indonesia adalah negara dengan mayoritas penduduk Muslim, meskipun bukan negara Islam namun pemikiran Islam banyak di konsumsi oleh masyarakat maupun politisi di Indonesia. Sehingga menghadirkan dua wajah peradaban yang melahirkan pemikiran tentang kekuasaan dan demokrasi menjadi penting untuk diketengahkan.
Pemikiran Politik Ibnu Taimiyah
Authors: Zaman Qamaruz
Published: December 2019

Tulisan ini membahas tentang pemikiran politik Ibn Taimiyah dalam sejarah politik Islam serta kontekstualisasinya di masa sekarang. Pertanyaan mendasar dalam kajian ini adalah tentang bagaimana bentuk sistem politik dan kenegaraan yang ditawarkan oleh Ibn Taimiyah, dan apakah teorinya masih relevan dengan kondisi sosial-politik saat ini. Ibn Taimiyah dengan keberaniannya menghapuskan/penolakan sistem kepemimpinan Khilafah dan Imamah, dengan tesisnya yang mengatakan bahwa rejim yang ditegakkan nabi adalah rejim nubuwwah dan bukan imamah, sedang imamah baru ada setelah nabi wafat menunjukkan bahwa ia mempunyai gagasan yang revolusioner dan pembaruan. Ia tidak ingin rakyat hanya menjadi objek dalam sebuah negara tapi Ia ingin rakyat menjadi subjek atas negara. Bagi Ibn Taimiyah, mekanisme/sistem pengangkatan kepala negara tidak terlalu penting, yang penting adalah bahwa orang yang menduduki jabatan itu harus benar-benar amanah dan adil. Ibn Taimiyah mensyaratkan dua hal bagi kepala negara, yaitu memiliki kualifikasi kekuatan (al-quwwah) dan integritas (al-amanat). Kekuatan dan integritas tersebut diperoleh melalui cara mubaya’ah (sumpah setia) yang diberikan oleh ahl al-Syawkah.

¿Dónde va el romboide?: Conocimientos geométricos que emergen a partir del uso del tangram
Authors: Mendoza von der Borch Tatiana , Block Sevilla David
Published: December 2019

En este artículo analizo los conocimientos geométricos que movilizan alumnos de primaria al hacer configuraciones con el tangram, a partir de la observación de dieciocho clases en un grupo de quinto grado de primaria de una escuela pública de la Ciudad de México. Muestro que esta actividad genera el despliegue de numerosas hipótesis, su puesta a prueba y a veces reelaboración por parte de los alumnos. En este proceso, se potencian también las interacciones entre pares, que a su vez enriquecen la interacción con la tarea. Concluyo apoyando la postura de que el aprendizaje de las figuras geométricas necesariamente requiere trabajo simultáneo con distintos tipos de figuras manipulables, pues ello permite, por contraste, reparar en las características de cada una de ellas.

Physics teaching in high school is still dominated by explicit learning models, relatively rarely empowering the potential of group inquiry based on social interaction. This has become one of the reasons for the lack of optimal student learning products. This study aimed to analyze the difference of effect between the group investigation (GI) model and the explicit learning (EL) model in achieving critical thinking skill, social attitude, spiritual attitudes, and student character in learning physics. To achieve this goal, a quasi-experimental study was conducted using a nonequivalence posttest only control group design. The study population was 16 classes (566 people) XI MIPA class students who came from two SMAs, namely 8 classes (280 students) SMA 1 Tabanan and 8 classes (286 students) SMA 1 Kediri Tabanan. The sample in each high school consisted of 2 classes selected by a random assignment technique. The whole sample was 4 classes (140 students, or 24.73% of the total population), 2 classes learned with GI model and 2 classes with the EL model, each learned sound wave and lightwave. Data on students' critical thinking skill was collected by 12 items test. Data on students’ social attitude, spiritual attitude, and  character were collected with a social attitude questionnaire which consists of 30 items, a spiritual attitude questionnaire which consists of 30 items, and  a character questionnaire which consists of 18 items. The research data were analyzed by one way MANOVA. The results showed that the GI model had a higher effect than the EL model in achieving critical thinking skill, social attitude, spiritual attitude, and the character of the students in learning sound wave and lightwave in  high school  physics.
Sustainability is the New Safety
Authors: Luca Christiaan
Published: December 2019

Editor’s Note: The oil and gas industry is under public scrutiny like never before on a host of health, safety, and environmental issues. These concerns are already affecting how companies operate and interact with the public. This series is intended to shed light on how the industry is actively confronting these challenges or how it should address them going forward.

I recently completed my season as SPE Distinguished Lecturer on the topic of managing nontechnical risks, or, in other words, managing business delivery in alignment with the broader interests of the societies in which we operate. It was a distinct privilege that took me to 18 countries and 30 engagements with oil and gas professionals around the world.

Among my many takeaways, three stand out:

Everywhere, independent of geography, culture, or political situation, the oil and gas industry is facing ever more regulatory scrutiny, higher expectations for responsible business conduct, and an increasingly vocal population. Many in my audiences saw this as a bigger challenge than technical and commercial ones.

There is no universal and proven approach to effective management of societal expectations and relationships. Companies large and small are experimenting their way forward, with as many successes as failures. Nobody can guarantee success up front.

There is no common terminology. Sustainability, sustainable development, corporate social responsibility, social license, societal or nontechnical risk management are all used in this universe and, by and large, have the same goal, i.e., developing and maintaining long-term, mutually beneficial relationships with societies in which we operate thanks to responsible social and environmental performance. I am not too worried what it is called as long as it yields the desired results. In this article I will be using both the terms “sustainability” and “societal relationships.”

Implementing Sustainability is Tough

Most companies realize that a glossy annual sustainability report or a charity program directed from headquarters is no longer enough. Society expects deeds and not words. A real contribution to sustainability needs to be expressed in the way we design, construct, and operate; in other words, it needs to be fully integrated in the way we do business.

However, as the spectrum of the 17 UN Sustainable Development Goals shows, sustainability covers a broad array of topics, from respecting human rights, delivery of clean and affordable energy, supporting climate action, to protecting the environment and supporting communities. Every discipline and department in the company, from drilling site to corporate office, has a stake in the contribution to sustainability.
Technology Focus: Well Integrity (January 2020)
Authors: Alcantara Santos Otto Luiz

Technology Focus

Fiber-optic technologies—distributed temperature sensing (DTS) and distributed acoustic sensing (DAS)—have been experiencing an increasing number of applications in the oil and gas industry as monitoring systems. In the area of well integrity, both technologies have been used in combination to monitor and evaluate qualitatively the cement placement and integrity in wells. An interesting technical article showing how these two technologies are used to monitor cement integrity in an actual well is selected as recommended additional reading. Ongoing research studies are also investigating casing deformation and downhole detection of hydro-carbon leakage.  

The use of these two technologies seems to have a very promising future when considering well-control situations. One potential application of DTS and DAS technologies is being evaluated now at Louisiana State University (LSU) as a part of a 3-year research project currently under way under the auspices of a grant by the Gulf Research Program to investigate the gas-in-riser issue. A 5,000-ft actual well at LSU was recompleted recently and instrumented with DTS and DAS for continuous monitoring information along the well and downhole gauges to record pressure and temperature at four different depths. These instruments were clamped to the outside of the production tubing installed inside the experimental well. A gas-injection line also was run into the well to displace nitrogen to simulate gas-in-riser situations.

The data gathered by the downhole instruments are expected to shed light on well-control attributes such as gas velocity and distribution, two-phase-flow patterns, and gas breakout from solution in nonaqueous drilling fluid inside the marine riser. The viability of generating distributed pressure profiles from DTS and DAS data collected in the experiments also will be investigated. Undoubtedly, the research findings will help detect gas-in-riser situations earlier and monitor deepwater managed-pressure drilling operations that may allow for a controlled amount of gas inside the riser.

Background Osteosarcoma represents a uncommon tumor occurring in bone possessing elevated rate of incidence and reduced rate of healing. Hence, developing effective therapeutic modalities to treat osteosarcoma is essential. Various long non-coding RNAs (lncRNAs) are engaged in prognostic and diagnostic processes of diseases. Thus, we identified the molecular mechanism of lncRNA PGM5-AS1 in progression of osteosarcoma.Methods Microarray-based analysis was employed to screen the osteosarcoma-related differentially expressed lncRNA. PGM5-AS1 level in osteosarcoma tissues and cells as well as the levels of microRNA-140-5p (miR-140-5p) and fibrillin-1 (FBN1) in osteosarcoma tissues were determined. Dual-luciferase reporter gene assay, RNA pull-down assay, and RNA immunoprecipitation assay were done to find out the relation among PGM5-AS1, miR-140-5p, and FBN1. shRNA, mimic, or inhibitor was applied to alter the levels of PGM5-AS1, miR-140-5p, and FBN1 in osteosarcoma cells to investigate how they regulated migration, invasion, and epithelial-mesenchymal transition (EMT) of osteosarcoma cells in vitro. The nude mice were injected with osteosarcoma cell line with depleted PGM5-AS1 to detect the role of PGM5-AS1 in tumorigenesis in vivo.Results PGM5-AS1 possessing elevated level in osteosarcoma was identified as the differentially expressed lncRNA in osteosarcoma. Osteosarcoma tissues exhibited low miR-140-5p expression and high FBN1 expression. Results confirmed that PGM5-AS competitively bound to miR-140-5p to upregulate FBN1. Also, hindering PGM5-AS1 and FBN1 or enforcing miR-140-5p dampened migration, invasion, and EMT of osteosarcoma cells in vitro. Furthermore, silencing PGM5-AS1 markedly inhibited tumorigenesis in vivo.Conclusion All in all, PGM5-AS1 depletion causes FBN1 reduction to retard osteosarcoma processes by negatively modulating miR-140-5p, highlighting PGM5-AS1 silencing as a biomarker for osteosarcoma management.

Authors: mendil samir , Aguili Taoufik
Published: December 2019

This article intends to analyze the Diraction phenomena of the incoming wave and provide a new approach for analyzing the frequency selective surface (Fss) by using a hybrid method combining Moment Method (MoM), optical physics (PO) with General theory of Diffraction (GTD). the frequency selective surface (Fss) is a periodic surface with identical two-dimensional arrays of elements arranged on a substrate dielectric. An incoming plane wave will either be transmitted (bandwidth) or reflected (stopband), completely or partially, depending on the nature of the array element. Today, FSSs have been extensively studied and there is tremendous growth in its design and implementation for different applications at the microwave to optical frequency ranges. In this review article, we present a new hybrid method form on Moment method and GTD for analyzing different categories of FSS based on the design of the structure, the array elements used, and applications. We also focus on the effects of diffraction, methodology, experimental verications of design examples, as well as on prospects and challenges, particularly in the microwave regime. We highlight their important performance metrics, especially about progress in this area could facilitate advanced electromagnetic innovation.
