Authors: Gultekin Mehmet Ali , Turk Hacı Mehmet , Yurtsever Ismail , Atasoy Bahar , Aliyev Altay , Yilmaz Temel Fatih , Alkan Alpay
Published: November 2019

Background:

This study aims to investigate the existence of any Diffusion Tensor Imaging
(DTI) value differences in Brain Metastases (BM) due to lung adenocarcinoma based on the
Epidermal Growth Factor Receptor (EGFR) gene mutation status.

Material and Methods:

17 patients with 32 solid intracranial metastatic lesions from lung adenocarcinoma
were included prospectively. Patients were divided according to the EGFR mutation
status as EGFR (+) (group 1, n:8) and EGFR wild type (group 2, n:9). The Fractional Anisotropy
(FA), apparent diffusion coefficient (ADC), normalized ADC (nADC), Axial Diffusivity (AD), and
Radial Diffusivity (RD) values were measured from the solid component of the metastatic lesions
and nADC values were calculated. DTI values were compared between group 1 and group 2. The
receiver-operating characteristic analysis was used to obtain cut-off values for the parameters presenting
a statistical difference between the EGFR gene mutation-positive and wild type group.

Results:

There were statistically significant differences in measured ADC, nADC, AD, and RD
values between group 1 and group 2. The ADC, nADC, AD, and RD values were significantly
lower in group 1. There was no significant difference in FA values between the two groups. Analysis
by the ROC curve method revealed a cut-off value of ≤721 x 10-6 mm2/s for ADC (Sensitivity=
72.7, Specificity=85.7); ≤0.820 for nADC (Sensitivity=72.7, Specificity=90.5), ≤ 886 for AD
(Sensitivity=81.8, Specificity=81.0), and ≤588 for RD (Sensitivity=63.6, Specificity=90.5) in differentiating
EGFR mutation (+) group from wild type group.

Conclusion:

A combination of the decreased ADC, nADC, AD, and RD values in BM due to lung
adenocarcinoma can be important for predicting the EGFR gene mutation status. DTI features of the
brain metastases from lung adenocarcinoma may be utilized to provide insight into the EGFR mutation
status and guide the clinicians for the initiation of targeted therapy.
Variation in the Level of Thyroid Markers in Association with Inflammation in Patients with Type 2 Diabetes
Authors: Siddiqui Khalid , George Teena P. , Joy Salini Scaria , Mujammami Muhammad
Published: November 2019

Background:

A possible relationship between thyroid hormones and glucose metabolism in
diabetes has already been established.

Objectives:

We aimed to evaluate the thyroid function markers and their relationship with inflammation,
which is considered as a pathogenic condition of diabetes.

Methods:

This cross-sectional study included 276 patients with type 2 diabetes. Serum levels of thyroid
(TSH, FT4, and FT3) and inflammatory markers (CRP, IL-6, and TNF-α) were measured.

Results:

The mean age of the subjects was 55.2 years and mean diabetes duration of 16.8 years. The
inflammatory markers showed significant differences with the tertiles of TSH and thyroid hormones.
TSH was significantly correlated with inflammatory markers, IL-6 (r = 0.13, P = 0.020) and TNF-α (r =
0.17, P = 0.003), while FT4 had a correlation only with TNF-α (r = 0.25, P = <0.001). FT3 was negatively
correlated with inflammatory marker IL-6 (r = -0.14, P = 0.020), HbA1c (r = -0.12, P = 0 .040),
and HOMA-IR (r = -0.17, P = 0.010).

Conclusion:

Abnormalities in the thyroid hormone metabolism are related to the increased inflammatory
activity as well as insulin resistance, and are associated with the disorders of glucose metabolism.
Perspectives of Patients and Professionals on Information and Education After Myocardial Infarction With Insight for Mixed Reality Implementation: Cross-Sectional Interview Study (Preprint)
Authors: Hilt Alexander D , Mamaqi Kapllani Kevin , Hierck Beerend P , Kemp Anne C , Albayrak Armagan , Melles Marijke , Schalij Martin J , Scherptong Roderick W C
Published: November 2019

BACKGROUND

Patient education is crucial in the secondary prevention of cardiovascular disease. Novel technologies such as augmented reality or mixed reality expand the possibilities for providing visual support in this process. Mixed reality creates interactive digital three-dimensional (3D) projections overlaying virtual objects on the real-world environment. While augmented reality only overlays objects, mixed reality not just overlays but anchors virtual objects to the real world. However, research on this technology in the patient domain is scarce.

OBJECTIVE

The aim of this study was to understand how patients perceive information provided after myocardial infarction and examine if mixed reality can be supportive in this process.

METHODS

In total, 12 patients that experienced myocardial infarction and 6 health care professionals were enrolled in the study. Clinical, demographic, and qualitative data were obtained through semistructured interviews, with a main focus on patient experiences within the hospital and the knowledge they gained about their disease. These data were then used to map a susceptible timeframe to identify how mixed reality can contribute to patient information and education.

RESULTS

Knowledge transfer after myocardial infarction was perceived by patients as too extensive, not personal, and inconsistent. Notably, knowledge on anatomy and medication was minimal and was not recognized as crucial by patients, whereas professionals stated the opposite. Patient journey analysis indicated the following four critical phases of knowledge transfer: at hospital discharge, at the first outpatient visit, during rehabilitation, and during all follow-up outpatient visits. Important patient goals were understanding the event in relation to daily life and its implications on resuming daily life. During follow-up, understanding physical limitations and coping with the condition and medication side effects in daily life emerged as the most important patient goals. The professionals’ goals were to improve recovery, enhance medication adherence, and offer coping support.

CONCLUSIONS

There is a remarkable difference between patients’ and professionals’ goals regarding information and education after myocardial infarction. Mixed reality may be a practical tool to unite perspectives of patients and professionals on the disease in a more even manner, and thus optimize knowledge transfer after myocardial infarction. Improving medication knowledge seems to be a feasible target for mixed reality. However, further research is needed to create durable methods for education on medication through mixed reality interventions.

Individual Values and Ideological Attitudes as Predictors of Prejudice against Others
Authors: Shamionov Rail M
Published: November 2019

The growth of social competition and modern trends of economic and social integration in the world encourage the study of the discriminatory attitudes of individuals and groups as a signiﬁcant barrier in the implementation of these processes. Despite the search for various grounds and factors for the development of discriminatory attitudes, studies of speciﬁc attitudes and values towards speciﬁc and generalized discriminated groups remain relevant. The aim of this research is to study the role of individual values and ideological attitudes in predicting the prejudice against Others. The study involved 217 people (men - 36 %), mean age M = 28.9; SD = 11.2.Aquestionnaire aimed at assessing the severity of the discriminatory attitude towards the representatives of a number of groups was used. The expression of values is determined by the Sh. Schwartz method. To assess the ideological attitudes of the right-wing authoritarianism, social domination, and belief in a dangerous and competitive world, we used a short version of J. Duckitt’s methodology by D.S. Grigoriev. As a result of the conﬁrmatory factor analysis, four generalized discriminated groups were identiﬁed: socially unprotected, dissident, outsider groups and social status groups. The data characterizing the ratio of ideological attitudes and the severity of discrimination of individual groups, as well as generalized groups was obtained. Based on structural modeling the common and speciﬁc values for each generalized discriminated group were identiﬁed.
Moral Basis for Ethnic Tolerance
Authors: Protasova Irina N , Sychev Oleg A
Published: November 2019

The article deals with the relation between ethnic tolerance and the moral sphere features on the basis of Moral Foundations Theory by J. Haidt. As a result of theoretical analysis we put forward a hypothesis that ethnic tolerance is entirely compatible with individualizing moral foundations (caring/not doing harm and fairness) but contradicts the binding moral foundations (loyalty, authority, sanctity). To test this hypothesis the research was carried out on a sample of 340 university students. The participants completed a questionnaire packet containing the “Tolerance index” questionnaire by G.U. Soldatova et al. and the “Moral foundations questionnaire” by J. Graham et al. The correlations between variables showed that ethnic tolerance was positively correlated with moral foundations ‘Care’ and ‘Fairness’ and negatively correlated with moral foundation ‘Authority’. Using path analysis we showed that ethnic tolerance is positively correlated with individualizing moral foundations and negatively correlated with binding moral foundations under the control of tolerance as a trait, gender and age. Our results also revealed unsatisfactory reliability of the “Social tolerance” scale of the “Tolerance index” questionnaire indicating the need for further investigation of the psychometric properties of this questionnaire. Our results support the hypothesis that ethnic tolerance is compatible with individualizing moral foundations, but contradicts the binding moral foundations. This fact demonstrates the moral inconsistencies of ethnic tolerance in the context of the individualizing and binding moral foundations.

Published: November 2019

The growing number of migrants makes it relevant to study the problem of acculturation to a new culture and to develop adequate methodological tools for assessing acculturation. Acculturation scales are a common tool for studying the adaptation of international citizens; in Russia, however, there is a shortage of them. The purpose of this study was to develop a short, easy to use, and not requiring translation into the mother tongue scale, aimed at determining the level of acculturation. When developing the methodology, we relied on the analysis of the available acculturation scales and on the recommendations proposed by van de Vijver et al. This study included the following stages: development of the initial version of the scale, testing and analysis of comprehensibility of the scale questions, psychometric analysis, repeated testing and psychometric veriﬁcation, and ﬁnally, determining external validity. At the various stages, the study covered 445 international students (42% female) from 71 countries. For psychometric analysis, descriptive statistics methods, Cronbach α and MacDonald ω coeﬃcients, bifactor analysis were used. To check the external validity, the method of expert evaluations (16 experts are teachers of the Russian language, basic disciplines, tutors on educational work) and correlation analyses were used. As a result, the proposed Acculturation Scale to Russia (ASR) has a high consistency (α = 0,89, ω = 0,91), three-factor structure (3 subscales were identiﬁed), and its satisfactory external validity. This scale can be used to assess the level of acculturation of international students in Russia.
Philosophical Issues of Semantics Raised by L.A. Novikov as a Key to Creating the Terminology Apparatus of Legal Linguistics (Category of Intentiuon)
Authors: Maslova Valentina A , Lavitski Anton A
Published: November 2019

In the late 20th century, in linguistics, inevitable changes were felt which were connected with the necessity in the transition of the science about language onto an absolutely new stage of its development. L.A. Novikov was one of the first among those who understood it. In the 80-s of the previous century he presented a new idea of semantics with deep philosophic understanding of its problem field, with the aspiration to seek solutions through the language interdisciplinary links. For the contemporary linguistics L.A. Novikov’s approaches are evident; however, they are not deprived of urgency and can become a clue to the solution of many problems especially in the field of terminology studies. In the present paper, on the basis of L.A. Novikov’s theory, an attempt is made to give the definition for the category of intentionality from the point of view of legal linguistics since the application of the available in the theory of law ideas for the new integrated direction is already insufficient. Legal linguistics has entered the development phase when there is an urgent necessity in shaping its own terminological vocabulary. This process can’t be “closed” and be limited by the approaches of the theory of law and theory of language: the shaping of the notion apparatus must be based on the ideas available in philosophy, psychology, physiology, education etc. This understanding of the problem finds its reflection in the present paper which makes it possible to define intentionality as a form of the implementation of the deliberateness of the act which is determined by the motive.
Hermeneutic Aspects of Bilingualism: the Role of Interlingual Interference
Authors: Sverdlova Nataliya A
Published: November 2019

The article is devoted to the problem of studying bilingualism. The object of study is the mechanism of acquiring a non-native language, considered in the context of the hermeneutic approach. For a deeper analysis of the process of acquiring a non-native language, the role of mental and metapsychic categories on the way to bilingual understanding of new knowledge about the world is considered. The activity of a person in the conditions of personal choice is a complex one, where the central place is given to consciousness. Understanding, as a function of consciousness, becomes a key issue in the interpretation of the reality where the bilingual is. The interpretation of all components of the “new” (other) culture and the world goes through language. The native language of the bilingual is associated through a particular set of “presetting” and “pre-understanding”. Gaining new experience in the conditions of conscious choice leads to the emergence of a double format of perception of the world, which does not contradict human nature, is a condition of completeness of the world view. The tasks of the researcher included the representation of linguistic personality in terms and concepts of hermeneutics; the definition of the basic mental processes that are characteristic of the formation of bilingual linguistic personality; the study of interference as a natural process and the result of the interpretation of the phenomena of reality. The article attempts to explain the role of consciousness and understanding in bilingual speech activity and to define the essence of interlanguage interference in the light of the applied approach. In interaction of conceptual and linguistic spheres of the system, appears for the interference systems. Due to irreversible changes in the structure of linguistic consciousness, interlingual interference becomes a natural process that can disrupt decoding under certain communication conditions.
Lexico-Semantic Transformations in Translation of Stories by V.M. Shukshin into English
Authors: Vekovishcheva Svetlana N , Guseinova Maria I , Priorova Elena M , Savchenko Elena P
Published: November 2019

This article is dedicated to the analysis of a lexico-semantic transformation in translation of fiction. The aim of the paper is to identify frequently and less frequently used translation transformations that we treat as cross-language transformations. These transformations are based on selection of the lexical units in target language closed in sematic meaning to those used in source language. V.M. Shukshin’s texts are used as the linguistic material for the conducted research. The translations are prepared by R. Daglish, L. Michael and J. Givens. The study shows that the most difficult units for translation are those having specific meaning due to cultural factors. Cultural associations in V.M. Shukshin’s texts are based on territorial and ethnographic information. Items actively participate in formation of the cultural code. They can be considered as a marker of cultural feature of a text. Translators’ functions include the pragmatic adaptation of texts and different comments. The phenomenon can be explained by the fact that the translator does not always possess enough background knowledge (as far as dialectal words are concerned) or in other words associative links between the object and the name it identifies. The results of the research explain the necessity of a new approach in professional practice.

Published: November 2019

Pendidikan merupakan suatu proses interaksi dua arah yang bertujuan untuk memberikan pengaruh terhadap kognitif, afektif dan psikomotorik, pengaruh tersebut dapat terstimulus secara signifikan tanpa terbatas dalam memori setiap individu. Pendidikan juga tidak hanya terbatas pada individu yang sempurna lahir dan bathin saja, tetapi pendidikan itu juga dapat dirasakan oleh komponen lain yang masih kurang dari segi psikologi, mental, atau dar segi fisiologisnya. pendidikan inklusif merupakan sebuah konsep pembelajaran yang menempatkan siswa berkebutuhan khusus dan siswa biasa dalam satu ruang sosial dengan kedudukan yang sejajar. Pendidikan yang menghargai perbedaan ini didasari oleh konsep kebermaknaan perbedaan yang unik pada tiap orang dan masyarakat. Ia merupakan pendidikan yang memberi kesempatan kepada peserta didik untuk bersosialisasi dengan sesama yang beragam baik dari segi fisik, agama, suku, dan lain-lain. Pendidikan multikultural mengandaikan sekolah dan kelas dikelola sebagai simulasi arena kehidupan nyata yang plural, terus berkembang dan berubah. Hal ini didasari oleh adanya kepekaan dan solidaritas di antara peserta didik. Potensi transedental, intelektual, moral dan estetis dikembangkan dengan cara mengintegrasikan nuansa moralitas dan spiritual di dalam kurikulum. Pelajaran agama pun tidak sekadar merupakan penyalehan individu namun lebih dari itu, pelajaran agama yang diberikan berfungsi untuk penyalehan sosial. Sikap dan sifat yang umumnya berkembang di masyarakat plural seperti di Indonesia antara lain memiliki solidaritas buta, etnosentrisme, partikularis, eksklusif serta masalah mayoritas-minoritas yang berujung pada ketidakadilan di dalam masyarakat. Sebagai negara yang memiliki beragam etnis, religi dan budaya, Indonesia perlu menerapkan pola pendidikan yang mampu menghadapi keberagaman.

Penelitian ini membahas tentang usulan perbaikan untuk pengurangan waste pada proses produksi dengan metoda lean manufacturing. Dalam penelitian ini dihasilkan waste yang paling dominan terdapat pada lini produksi saxophone dengan total skor 3 yaitu defect, dan unnecessary motion dan unnecessary transportation dengan masing – masing skor 2. Sedangkan faktor penyebab yang mempengaruhi pemborosan dapat diketahui dengan menggunakan fault tree analysis ( FTA ) dimana pada waste defect penyebab dasar terjadinya waste adalah hanya ada 2 operator buffing, human eror dan belum adanya jadwal penggantian kompon secara berkala. Sedangkan pada waste unnecessary motion penyebab waste adalah lot keranjang cuci hanya muat 5 pcs dan tidak ada meja untuk operator melakukan pemindahan material. Dan pada waste unnecessary transportation penyebab waste adalah human eror yaitu operator yang mengobrol dan lamanya waktu transportasi yang disebabkan oleh tata letak mesin yang berjauhan. Sedangkan hasil dengan menggunakan metode failure mode effect analysis ( FMEA ) dipilih 3 tindakan yang memiliki nilai RPN paling tinggi. Dimana usulan perbaikan yang terpilih adalah perubahan layout dengan mendekatkan proses plasma welding dengan seam roller, menambah kapasitas keranjang cuci sehingga dapat meminimasi terjadinya gerakan yang berulang pada transportasi, dan menjadwalkan penggantian kompon buffing secara berkala untuk meminimasi kompon yang mengelupas dan menemple pada part karena sudah usang.
El concepto de Rectángulo Equivalente para la caracterización de la forma de una cuenca
Authors: Cañibano Alejandra , Gandini Marcelo
Published: November 2019

En este trabajo se rescata la importancia de la enseñanza de la geometría como modeladora del espacio en el que estamos inmersos, para lo cual se presenta la resolución de un problema relacionado con cierto tipo de disciplinas como la cartografía, la geografía, la hidrología a través de la caracterización de la forma de una cuenca hidrográfica. Para ello se hace uso del concepto de rectángulo equivalente. Es importante aclarar que en el desarrollo de este trabajo, se presentan dos variables asociadas a la morfometría: el área y el perímetro las cuales también permiten describir la forma de una cuenca y los efectos asociados a la misma. A su vez se el trabajo también incluye el desarrollo de las funciones cuadráticas para su resolución. Las conclusiones demuestran que no son los “colegios emblemáticos” los que obtienen las mejores calificaciones, tampoco los que se ubican en las grandes ciudades, ni los más caros, sino aquellos que sirven a las capas medias de la población y que se encuentran en las ciudades intermedias del país.

Published: November 2019

Background: The breast cancer etiology remains still unclear. Although there have been various studies across the globe, proper prevention protocols or strategies for breast cancer remains limited. Regular breast self-examination could influence management, quality of life, mortality, as well as prognosis of breast cancer in any population. The current study was aimed to investigate the health beliefs and knowledge among Saudi women regarding breast self-examination. Methodology: A cross-sectional observational survey study was carried out in the Aseer region, Saudi Arabia using an online self-developed questionnaire distributed via Google forms among the general public. All female citizens and residents in the Aseer area were included in this study. Data were represented in the form of frequencies (number of responders) and valid percentages for categorical variables. Analysis of variance test was utilized to compare means between different subgroups. A p-value < 0.05 was considered as statistically significant. Results: A total of 473 participants completed the survey. The average score for behavior questions was found at 2.85 ± 1.47, while the average rating for knowledge questions was found at 114.51 ± 36.33. Females aged between 50 and 60, divorced, or with a secondary school degree showed significantly higher (p < 0.001) levels for knowledge. While females aged between 31 and 35 years old divorced with a university degree had a significantly better (p < 0.001) behavior toward breast cancer and breast self-examination. Conclusion: A poor level of knowledge and poor practices and behavior toward breast self-examination was observed among females of the Aseer region, Saudi Arabia. Further studies are required in other regions of the country to assess the level of knowledge and behaviors at a broader level to explore the exact reasons behind this poor practice observed.

Published: November 2019

The control of land by the state is stated in Article 33 paragraph (3) of the 1945 Constitution of the Republic of Indonesia (UUD 1945). Based on this article, it means that the State has authority over land tenure, this encourages the writing of a journal on the application of social functions and the determination of compensation that occurs in the land sector. This research was conducted because the authors see that there are still many disputes related to the implementation of the social function itself and the application of the determination of compensation as stipulated in the provisions relating to this matter it is caused because the application in real life has not been running optimally. This study aims to find out how the government’s authority should be for land tenure and its relation to social functions and the determination of compensation. The location used as a case study is located in Batu Jaya Village, Tangerang City. Data collection is done by interviewing several related parties and also conducting a literature study by finding sources related to government authority over land tenure, the concept of social functions, and the determination of compensation. The results of this study indicate that the government has the power to grant land rights and revoke land rights in the public interest.

Published: November 2019

Telah dilakukan estimasi nilai Mc, nilai-b dan nilai-a menggunakan data gempa bumi dari katalog USGS (United States Geological Survey) dari Januari 1970 sampai Maret 2015 dengan batas 90Â°BB - 106Â°BB dan 6Â°LU - 6Â°LS dengan skala magnitudo Mwâ‰¥4 SR sampai 9 SR pada kedalaman maksimum 300 km yang meliputi wilayah Sumatera dan Samudera Hindia. Dalam penelitian ini digunakan Software ZMAP under MATLAB. Estimasi Mc dilakukan secara spasial dan temporal dengan menggunakan dua metoda yaitu metoda MAXC dan EMR. Variasi nilai Mc secara spasial kemudian dipetakan dengan bin size 250 secara spasial dan secara temporal persepuluh tahun untuk melihat evolusi nilai Mc selama empat dekade terakhir. Dari analisis diatas, diperoleh Mc sekitar 4,2 SR sampai 5,6 SR (nilai Mc rata-rata adalah 4,6 SR), Nilai-b berkisar 0,6 sampai 1,1 dan variasi nilai-a berkisar 5 sampai 7,5.

Published: November 2019

Telah dilakukan pembuatan material sensor kelembaban relatif (RH) berbasis selulosa ubi gajah danÂ polianilin (PANi). Pembuatan PANi-selulosa menggunakan metode grafting dengan variasi selulosa 1-5 gÂ selulosa pada 10 mL PANi. Inisiator CuSO4 (1 M) digunakan untuk membentuk radikal bebas, sehingga molekul selulosa bisa masuk pada tulang punggung PANi. PANi-selulosa hasil sintesis dikarakterisasiÂ mengunakan FTIR dan Spektrofotometer UV-VIS. Pengukuran resistansi dari film tebal PANi-selulosaÂ dilakukan untuk setiap variasi penambahan selulosa berdasarkan perubahan kelembaban relatif. Hasil karakterisasi FTIR dan Spektrofotometer UV-VIS menunjukkan bahwa terjadinya pergeseran spektra IRÂ dan serapan optik PANi oleh pencangkokan selulosa yang mengindikasikan keberhasilan pencangkokanÂ PANi-selulosa. Penambahan massa selulosa dapat menurunkan nilai resistansi film PANi-selulosa. SecaraÂ keseluruhan, film PANi-selulosa memiliki pola resistansi yang berkesesuain dengan tingkat kelembabanÂ relatif, semakin tinggi nilai kelembaban relatif semakin rendah resistansi PANi-selulosa. Dari grafik kelembaban relatif terhadap resistansi, sampel terbaik sebagai material sensor RH adalah sampel denganÂ 10 mL PANi pada 3 g selulosa dengan koefisien korelasi sebesar 0,9640. Pencangkokan selulosa padaÂ PANi meningkatkan sifat hidroskopis, matrik-matrik hidrofilik dan meningkatkan jumlah molekul uap air yang terperangakap di dalam PANi.

Published: November 2019

Distribusi spasial dan temporal petir di Sumatera Barat telah diteliti dengan menggunakan data satelit Tropical Rainfall Measuring Mission-Lightning Imaging Sensor (TRMM-LIS) selama 16 tahun pengamatan (1998-2013). Hubungan antara petir dan curah hujan diteliti dengan memanfaatkan data TRMM 3B43. Hasil penelitian menunjukkan bahwa petir di Sumatera Barat banyak terjadi di darat dengan densitas tertinggi terjadi pada bulan Desember, Januari dan Februari (DJF). Petir di darat banyak terjadi pada sore hari mulai jam 17.00 LST hingga tengah malam dan kabupaten Dharmasraya merupakan daerah yang memiliki densitas kilatan petir tertinggi terutama selama periode DJF. Siklus diurnal petir konsisten dengan siklus migrasi awan dari laut ke daratan Sumatera yang ditemukan oleh peneliti sebelumnya. Hubungan curah hujan dan petir di Sumatera Barat bervariasi antara satu kabupaten dengan kabupaten lainnya. Berdasarkan nilai regresi linier antara petir dan curah hujan terlihat bahwa daerah yang memiliki korelasi yang cukup kuat antara densitas petir dan curah hujannya adalah Kabupaten Solok,Â  Solok Selatan, Padang Pariaman, dan 50 Kota sedangkan daerah yang memiliki korelasi yang rendah adalah Kepulauan Mentawai, Pesisir Selatan, dan Agam. Dengan demikian, di beberapa kabupaten petir dapat menjadi indikator untuk penentu curah hujan tetapi tidak untuk beberapa kabupaten yang lain.Kata kunci: distribusi petir, Sumatera Barat, TRMM

Pembuatan zeolit sintetis berbahan abu dasar batubara menggunakan metode peleburan alkali hidrotermal telah dilakukan dengan pemberian sonikasi. Sebelum disintesis, kandungan abu dasar batubara diuji dengan XRF. Hasil XRF menunjukkan bahwa abu dasar yang digunakan memiliki kandungan SiO2 sebanyak 57,236% dan Al2O3 sebanyak 33,172%. Abu dasar dan NaOH dilebur dengan perbandingan 1:1,2 g. Sampel yang telah dilebur, dilarutkan dengan larutan NaAlO2, kemudian diberikan pengaruh sonikasi sebelum proses kristalisasi zeolit (hidrotermal). Variasi waktu sonikasi diberikan pada 4 sampel adalah 0,5; 1; 1,5 dan 2 jam serta 1 sampel tanpa sonikasi sebagai perbandingan. Sampel hasil sintesis dicuci dengan aquades hingga mencapai pH 9-10. Karakterisasi sampel yang dilakukan meliputi karakterisasi morfologi permukaan menggunakan SEM dan pengukuran konduktivitas listrik menggunakan LCR-meter. Hasil karakterisasi SEM menunjukkan sampel dengan pemberian ultrasonik memiliki morfologi permukaan yang lebih seragam daripada sampel tanpa pemberian sonikasi. Nilai konduktivitas listrik yang dihasilkan berkisar dari 0,05206 x 10-6 - 2,1188 x 10-6 S/cm dan berada pada rentang bahan semikonduktor. Zeolit dengan pemberian sonikasi selama 1,5 jam mempunyai konduktivitas listrik tertinggi dibandingkan dengan sampel lain.

Telah dilakukan analisis kecepatan menggunakan metode tomografi pada data seismik 3DÂ  Lapangan Y lepas pantai Texas dengan software Opendtect. Model kecepatan baru dibuat dengan mengoreksi kurva residual moveout (RMO) pada gather CIG (common image point) dengan menggunakan model kecepatan awal yang diperoleh secara konvensional sebagai masukan. Iterasi dilakukan sampai diperoleh kurva RMO yang datar. Selanjutnya model kecepatan baru yang dihasilkan melalui metode tomografi digunakan sebagai acuan nilai kecepatan untuk proses stacking dan migrasi. Penampang seismik hasil migrasi dengan nilai kecepatan baru menunjukkan peningkatan yang cukup baik. Struktur geologi yang berupa patahan dan pola-pola reflektor di kedalaman terlihat lebih jelas dibandingkanÂ  dengan penampang seismik awal.

Telah dilakukan sintesis nanopartikel Magnesium Oksida (MgO) dengan metode presipitasi. Nanopartikel MgO disintesis menggunakan Polietilen Glikol (PEG) yaitu PEG 2000 (sampel 1), PEG 4000 (sampel 2), dan PEG 6000 (sampel 3) sebagai template dengan suhu sintering 600 C selama 3 jam. Sampel dikarakterisasi dengan menggunakan X-Ray Diffraction (XRD) untuk mengetahui ukuran dan struktur kristal, sedangkan Scanning Electron Microscopy (SEM) digunakan untuk mengidentifikasi morfologi permukaan sampel. Hasil karakterisasi XRD menunjukkan bahwa ukuran kristal pada sampel 1, sampel 2 dan sampel 3 berturut-turut adalah 66,76 nm, 74,15 nm, dan 66,79 nm. Hasil SEM menunjukkan bahwa masih terdapat penggumpalan (aglomerasi) antar partikel MgO pada ketiga sampel. Semakin besar berat molekul PEG, maka semakin besar pula persentase puncak nanopartikel MgO yang dihasilkan.Â Kata kunci: nanopartikel MgO, polietilen glikol, presipitasi
