On fluorescent sensing of metal ions using water extracts of Salvia officinalis
Authors: SARGİN İdris 
Published: December 2019

Sensing of metal ions using fluorometric tools has wide applications in
chemical, biological and environmental analysis. Plant phytochemicals, like
flavonoids, exhibit intense fluorescence upon excitation by UV light. Leaves
sage (Salvia officinalis), which is
rich in polyphenolic and flavonoids compounds, were extracted using Soxhlet and
microwave-assisted extractors. The extraction methods led to variations in the
phytochemical composition of the extracts, which in turn affected their
interaction with metal ions. Despite the variations in the composition, both of
the extracts gave high fluorescence emissions when excited at 365 nm.
Variations in fluorescence emissions of the extracts were studied in upon
addition of each metal ion; i.e., Li+,
Na+, K+, Cs+, Be2+, Mg2+,
Sr2+, Ba2+, Al3+, Tl3+, Ge4+,
Sn4+, Pb2+, Sb3+, Bi3+, Se4+,
Cu2+, Ag+, Zn2+, Cd2+, Ti4+,
Cr3+, Cr6+, Mo6+, W6+, Mn2+, Fe3+,
Ni2+, Co2+ and Pd2+. When they were added into
the Soxhlet extract, some ions (Cr3+, Pb2+, Co2+)
induced intense fluorescence and some (Ge4+, Mg2+, K+,
Na+) ions quenched the fluorescence emission. As for
microwave-assisted extract, the addition of Sr2+, Mg2+
and Co2+ ions enhanced the fluorescence emission of the extract, but
Fe3+, Be2+ and Cs+ lowered the fluorescence
intensity. However, the results of the study should be considered as
introductory and further selectivity and sensitivity studies should be done for
each extract if they are used for sensing of metal ions. Yet, this study
demonstrated that sage extracts has a potential for fluorescent sensing of
certain metal ions.
Çin’in ekonomik büyümesinde ivme kaybı: İhracat-kamu harcamaları etkisi, Toda-Yamamoto nedensellik testi
Authors: TEMİZ DİNÇ Dilek 
Published: December 2019

Çin, uyguladığı başarılı
reformlar ve dışa açılma politikası ile önemli bir ekonomik büyüme performansı
yakalayarak, gelişmiş ekonomilerle arasını hızla kapatan bir ekonomi görünümüne
sahipti. Ancak, 2010 yılından itibaren büyüme hızı yavaşlamaya başladı. Büyüme
hızındaki bu ivme kaybının birçok nedeninin olmasıyla birlikte, Çin’in ihracat
artış hızının ve Çin’deki kamu harcamalarının azalması başlıca nedenler
arasında sayılabilir. Bu çalışmada, Çin’in ihracatı, kamu harcamaları ve
ekonomik büyümesi arasındaki nedensellik ilişkisi, Toda-Yamamoto nedensellik
testi ile araştırılmıştır. Çalışmada, 1960-2017 dönemini kapsayan yıllık
veriler kullanılmıştır. Ampirik analizler sonucunda, Çin’in ekonomik büyümesi
ile kamu harcamaları arasında çift yönlü, ihracatı ile ekonomik büyümesi
arasında ise ihracatından ekonomik büyümesine doğru tek yönlü bir nedensellik
ilişkisi saptanmıştır. Bu bulgular göre,
Çin’in ekonomik büyümesi ile kamu harcamaları ilişkisi, hem Wagner’in hem de
Keynes’in hipotezlerini desteklemekte, ekonomik büyümesi ile ihracatı ilişkisi
ise ihracata dayalı büyüme hipotezini desteklemektedir. Çalışmada ayrıca
varyans ayrıştırması analizi ile Çin’in ekonomik büyümesi üzerinde ihracatının
etkisinin kamu harcamalarının etkisinden daha fazla olduğu sonucuna
ulaşılmıştır.

Study of subclinical hypothyroidism in elderly and its correlation with lipid profile
Authors: Mohanty Namita , Parhi Satyajit 
Published: December 2019

Background: Although hypothyroidism accompanying dyslipidemia previously recognized as important risk factor for cardiovascular disease, but now subclinical hypothyroidism emerged as important risk factor for atherosclerosis and myocardial infarction especially in elderly people. Subclinical Hypothyroidism (SCH) is a state characterized by normal serum T3 and T4 level with elevated TSH level having minimal signs and symptoms. There are limited studies on SCH and dyslipidemia in elderly people in India, so this study was undertaken to correlate thyroid function abnormality with lipid profile in elderly population. Methods: This observational study was conducted in 74 elderly people more than 60 years age group having symptoms of SCH i.e. fatigue, weakness mild thyroid swelling, weight gain etc. who did not previously have a diagnosis of hypothyroidism, diabetes mellitus, previous thyroidectomy, renal failure, hepatic failure, systemic hypertension etc. They had normal T3, T4 level and raised TSH value. Cases with TSH value >5 mIU/L but normal T3, T4 level were evaluated further for lipid profile. Results: Elderly females suffered more from SCH in the age group of 60-70 years. Participants with SCH had significantly higher cholesterol (p value=0.0216), higher LDL (p value=0.0241) and higher triglyceride (p value =0.0004) with increasing TSH showing positive correlation. There is no significant correlation between decreasing HDL and TSH value.Conclusions: All elderly people should be routinely screened for thyroid function abnormality. Those have SCH should also be evaluated for dyslipidemia so that they can be treated with lipid lowering drugs and low dose thyroxine judiciously to prevent atherosclerosis.
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.
ULAMA-DIFABEL: MENARASIKAN EKSPRESI KULTURAL MASYARAKAT BANJAR DALAM LENSA STUDI DISABILITAS

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.

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.

Published: December 2019

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.
