It is personal philosophy of teaching. Approach can also have many methods. Teaching approach is like the form or the way we teach or how we do it. There are various approaches which are used in teaching learning process. The following are the main approaches of teaching learning:
Effectiveness of Vedic Mathematics in the Classrooms
Authors: Katgeri Archana V.
Published: November 2017

Vedic Mathematics was discovered by Indian mathematician Jagadguru Shri Bharathi Krishna Tirtha in the period between A.D. 1911 and 1918. Later the findings were published in form of a book on Vedic Mathematics by Tirthaji Maharajwho was also known as Bharati Krsna. Bharati Krsna was born in 1884 and died in 1960. He was a brilliant student, obtaining the highest honours in all the subjects he studied, including Sanskrit, Philosophy, English, Mathematics, History and Science. When he heard what the European scholars were saying about the parts of the Vedas which were supposed to contain mathematics he resolved to study the documents and find their meaning. Between 1911 and 1918 he was able to reconstruct the ancient system of mathematics which we now call Vedic Mathematics.
Efficacy and Long-Term Safety of C.E.R.A. Maintenance in Pediatric Hemodialysis Patients with Anemia of CKD

Published: November 2017

Background and objectives

The study was conducted to identify a conversion factor for switching from previous erythropoiesis-stimulating agents (ESAs) to continuous erythropoietin receptor activator–methoxy polyethylene glycol-epoetin beta (C.E.R.A.) and to document the efficacy and long-term safety of C.E.R.A. in pediatric patients with anemia of CKD undergoing hemodialysis.

Design, setting, participants, & measurements

In this open-label, multicenter study, patients aged 6–17 years, with stable chronic anemia of CKD, undergoing hemodialysis received C.E.R.A. every 4 weeks, at a starting dose determined by previous weekly epoetin alfa/beta or darbepoetin dosing. After a 16-week dose-titration and a 4-week evaluation period, patients with stable hemoglobin could enter a 1-year optional safety extension.

Results

A total of 64 patients were enrolled. A conversion factor (4 µg every 4 weeks for each weekly dose of 125 IU epoetin alfa/beta or 0.55 µg darbepoetin) was identified that allowed patients to maintain hemoglobin within target levels on switching to C.E.R.A. from another ESA. Using this conversion factor, the adjusted mean change in hemoglobin from baseline to evaluation was −0.09 g/dl (95% confidence interval, −0.45 to 0.26); 81% of patients maintained hemoglobin within 10.0–12.0 g/dl and 75% maintained hemoglobin within 1.0 g/dl of baseline. Results were consistent across age groups (6–11 and 12–17 years) and previous ESA. Thirty-seven patients entered the safety extension period and 17 completed 73 weeks of treatment. Most withdrawals were for kidney transplantation. A total of 70% of patients had hemoglobin within 10.0–12.0 g/dl at last observation, and 62% were within ±1.0 g/dl of baseline. Safety was similar to studies in adult patients, with no new signal detected.

Conclusions

Using a defined conversion factor, 4-weekly C.E.R.A. was efficacious in maintaining hemoglobin levels in pediatric patients with stable anemia of CKD undergoing hemodialysis, switching from maintenance treatment with epoetin alfa/beta or darbepoetin. Safety was consistent with the known C.E.R.A. safety profile in adults.

O objetivo geral deste trabalho é observar como os processos multicêntricos do sistema jurídico permitem o diálogo entre ordens jurídicas de diferentes níveis, possibilitando falar-se em um Direito Global. Como hipótese principal, sugere-se que tem ocorrido, a partir do século XX (pelo menos), a emergência de um Direito Global, o qual pressupõe não apenas as comunicações atinentes ao Estado (leis, tratados/convenções, regulamentos, jurisprudência de Cortes estatais), mas também, de outras ordens não estatais – tais como a lex sportiva. Esse Direito Global, quando assim observado, é compreendido como reflexivo não apenas em relação às suas próprias comunicações, ocorrendo também verdadeiros diálogos entre ordens das mais variadas origens (estatais ou não). Objetivos específicos: i) descrever a Lex Sportiva, ordem jurídica transnacional, decorrente da relação reflexiva entre o Direito e a regulação esportiva; ii) analisar o transconstitucionalismo como metodologia dialogal-reflexiva para a observação da lex sportiva; iii) analisar o caso do atleta Jean-Marc Bosman, que desencadeou evolução nas relações profissionais entre atletas e clubes, a partir da segunda metade da década de 1990, exemplo de diálogo reflexivo entre a lex sportiva e ordens jurídicas estatais.

The chemical control method of blister blight (Exobasidium vexans Massee) on tea could inflict various negative impacts. In order to obtain an environmentally sound control method of blister blight disease, a nursery trial has been conducted to know the effectiveness of bacterial combinations. The trial was carried out at Gambung experimental garden, with seven treatments and four replications. The indigenous microbial codes are Azoto II-1, Endo-5 and Endo-76. The treatments tested comprised: control (without bacteria),Â  Azoto II-1 25% + Endo-5 75%; Azoto II-1 50% + Endo-5 50%; Azoto II-1 75% + Endo-5 25%;Â  Azoto II-1 25% + Endo-76 75%; Azoto II-1 50% + Endo-76 50%; and Azoto II-1 75% + Endo-76 25%. All of the treatments was applied as a soil drench, 50 ml/plant with bacterial concentration at 0,5%. The parameter observed was blister blight disease intensity, plant heights, stem diameter, leaves number, root length, and root volume. The results showed that the combination of Azoto II-1 75% + Endo-5 25% could suppress the intensity of blister blight disease with disease intensity 1.27%. The treatments also affected plant heights, stem diameter, leaves number, root length, and root volume, 15.32 cm; 3.38 cm; 8.05 cm; 18.25 cm and 2.37 cm, respectively.

Published: November 2017

L-theanine is amino acid contained in tea (Camellia sp.) leaves having ability as relaxation compound. Combination of L-theanine and other compounds produced from fermentation of green tea extract by Kombucha starter generates Kombucha tea with unique taste and better relaxation functional. The concentrate of Kombucha tea as functional drink for relaxation (anti stress) was produced by purification on fermented green te extract through 0.2 Âµm MF membrane fitted in stirred microfiltration cell (SMFC)Â  at stirrer rotation speed of 200 rpm and 400 rpm, and pressure of 30 psia. Purification was conducted on 4 grades of Kombucha tea from local green tea extract with rich L-theanine, such as Pekoe, Dewata, Arraca Kiara and Arraca Yabukita as a result of purification by MF module. Kombucha tea produced through fermentation at 1 part of permeate and 1 part of water ratio using Kombucha (5%, v/v) starter riched by sucrose of 10% (w/v) under room temperature for 7 days. Based on the best L-theanine concentration, the result of experiment showed that SMFC at stirrer rotation speed of 400 rpm was able to retain L-theanine in retentate from Kombucha tea of Arraca Kiara, Arraca Yabukita, Dewata, and Pekoe grades, subsequent 29.1, 96,53, 44.62 and 71.54% (w/v) from prior to process as feed. In other words, optimization condition was reached at Kombucha tea of Arraca Yabukita grade producing retentate or concentrate of KomÂ­bucha tea with L-theanine, total polyÂ­phenol, reducing sugar, total solids, and total of titratable acids of 2.5605% (w/w), 3.4314% (w/w), 14 mg/mL, 4.8947% (w/w), and 0.2195% (v/v) respectively.

Published: November 2017

Empoasca (Empoasca flavescens) is a major pest of tea plant in almost all elevations and can lead of lost production more than 40%.Â  Chemical insecticide is still use to control this pest. In a long term, thisÂ  could be increase the cost as well as environmental damage. To support an environmentally sound control method, an experiment has been conducted by using active ingredient of surawung langit leaf extract and using of mass controlling tool. The experiment was carried out at a productive tea plant of two years prunning, clone GMB-7, block B4, Pasir Sarongge Experimental Garden, Cianjur.Â Â  The experiment was arraÂ­nged in a factorial randomized block design with eight treatments, and replicated three times. The aim the experiment was to evaluate the effectiveness of botanical insect glue surawing langit (salvinia hyspanica) and mass controlling application technique on empoasca in tea plant. Result showed that botanical insect glue surawing langit at 10 and 20% applied using mass controlling tool with two blowers were effective in catching of Empoasca as swell as its attack intensity and shoot production.Â

Published: November 2017

Climate change has been influencing rainfall pattern so that it would be necessary to see the impact of that changed on tea plantation. The experimental area coverage lowland (600 m asl), midland (800-1000m asl) and highland (>1.000 m asl) tea plantation and each altituted represented by three tea estate in West Java. The rainfall data collected since 2005 up to 2014 from each estate and water deficit has been count through the method develop by Wijaya (1996). The results showed that the rainfall pattern has been changed by La-Nina and El-Nino during 2005-2014 in tea estate either in lowland, midland or highland in the last decade. The climate change causedÂ  rainfall decreasing and increasing on dry month (the rainfall < 100 mm). Eventhough on 2009 there is an significantly increasing of the rainfall but after 2009 until 2014, the rainfall tend to decrease. After El-Nino on late 2009 and early 2010, lowland tea estate on Subang Regency facing water deficit until 5 months with R (defisit water index) far below 1 even there is no El Nino. The tea plantation at midland area (Cianjur Regency) facing 5 months water deficit per year, but the R index close to 1. While in highland tea plantation (Bandung Regency), the water deficit only happend on certain month on certain year although there is a month with zero rainfall. Water deficit could be happend because of runoff on soil surface stimulate by low ability of soil to keep the water.

Published: November 2017

The application of Big Data and time series models is currently at an early stage. This paper examines the relevance and use of time series analyses for Big Data and business analytics by discussing the emergence of Big Data in business, presenting time series models, and providing an example of how time series models can be efficiently and effectively applied in accounting and auditing using Big Data. Using sophisticated Big Data and time series models, millions of transactions can be searched to spot patterns and detect abnormalities and irregularities. The time series model and Big Data analysis presented in this paper provide policy, practical, educational, and research implications. Businesses and management can use our suggested time series model and Big Data analysis in their predictive models of managerial strategies, decisions, and actions. Business schools and accounting programs can integrate the time series model, Big Data, and data analytics into business and accounting education.

Insulin has a narrow therapeutic index, reflected in a small margin between a dose that achieves good glycemic control and one that causes hypoglycemia. Once injected, the clearance of exogenous insulin is invariant regardless of blood glucose, aggravating the potential to cause hypoglycemia. We sought to create a “smart” insulin, one that can alter insulin clearance and hence insulin action in response to blood glucose, mitigating risk for hypoglycemia. The approach added saccharide units to insulin to create insulin analogs with affinity for both the insulin receptor (IR) and mannose receptor C-type 1 (MR), which functions to clear endogenous mannosylated proteins, a principle used to endow insulin analogs with glucose responsivity. Iteration of these efforts culminated in the discovery of MK-2640, and its in vitro and in vivo preclinical properties are detailed in this report. In glucose clamp experiments conducted in healthy dogs, as plasma glucose was lowered stepwise from 280 mg/dL to 80 mg/dL, progressively more MK-2640 was cleared via MR, reducing by ∼30% its availability for binding to the IR. In dose escalations studies in diabetic minipigs, a higher therapeutic index for MK-2640 (threefold) was observed versus regular insulin (1.3-fold).

Published: November 2017

OBJECTIVE To evaluate the effect of brachycephaly and body condition score on respiratory thermoregulation of healthy dogs.

DESIGN Prospective study.

ANIMALS 52 brachycephalic and 53 nonbrachycephalic dogs.

PROCEDURES All dogs were exposed to a cool treatment (temperature, 21.8 ± 1.7°C [71.2 ± 3.1°F]; relative humidity, 62.2 ± 9.7%; and ambient enthalpy, 47.7 ± 6.6 kcal/kg) and then a hot treatment (temperature, 32.9 ± 1.7°C [91.2 ± 3.1°F]; relative humidity, 51.9 ± 9.8%; and ambient enthalpy, 74.8 ± 8.7 kcal/kg; heat stress) at least 1 hour later. For each treatment, dogs were allowed to acclimatize to the environment for 15 minutes and then were placed in a sealed whole-body plethysmograph for continuous measurement of the respiratory pattern for 10 minutes. Treatment was discontinued if a dog developed signs of respiratory distress. Respiratory variables and body temperature were compared between the 2 breed types (brachycephalic and nonbrachycephalic) and between treatments.

RESULTS Body condition score was positively associated with body temperature independent of environmental conditions or breed type and negatively associated with tidal volume. Brachycephalic dogs had a greater increase in respiratory rate in response to heat stress than did nonbrachycephalic dogs.

CONCLUSIONS AND CLINICAL RELEVANCE Results indicated that brachycephalic dogs had decreased capacity for thermoregulation, compared with nonbrachycephalic dogs, but body condition score was a greater determinant of body temperature than breed type. Nevertheless, both upper airway conformation and body condition score should be considered when evaluating whether an individual dog is capable of tolerating heat stress.

Authors: Baird Aubrey N. , Mohamed Ahmed , Moore George E. , Hawkins Jan F.
Published: November 2017

OBJECTIVE To evaluate reproductive performance and productive longevity of dairy cows treated for left displaced abomasum (LDA) with 1 of 2 surgical techniques (omentopexy vs pyloro-omentopexy).

DESIGN Retrospective case series.

ANIMALS 87 Holstein cows that underwent omentopexy or pyloro-omentopexy for LDA during a 5-year period.

PROCEDURES For each cow with LDA, the most recent date of calving, age at time of surgery, and surgical procedure were recorded. Dairy records of cows treated for LDA in the 5-year period were reviewed to determine their reproductive performance. Records available for up to 4 years after the last surgery (ie, when all treated cows had left the herd) were reviewed to determine cull dates and reasons for treated and untreated cows in the herd.

RESULTS Of the 87 cows with LDA, 58 underwent pyloro-omentopexy and 29 underwent omentopexy. Cows in the 2 treatment groups did not significantly differ in age. Fifty-six cows completed > 1 subsequent lactation cycle after surgery. The median time that cows with LDA remained in the herd was 566 days (range, 24 to 1,838 days); the times for the 2 treatment groups did not significantly differ. For treated and untreated cows, cull rates for reproductive failure or other problems were similar. Four (14%) omentopexy–treated cows and no pyloro-omentopexy–treated cows had a reoccurrence of LDA.

CONCLUSIONS AND CLINICAL RELEVANCE Results indicated that cows with LDA that underwent omentopexy or pyloro-omentopexy had similar cull rates and reasons as unaffected herd mates over their productive time in the herd. Between the 2 treatment groups, only the LDA reoccurrence rate differed.

OBJECTIVE To characterize adverse reactions to oral administration of a combination of praziquantel and pyrantel embonate or pyrantel pamoate, with or without oxantel embonate, in captive cheetahs (Acinonyx jubatus).

DESIGN Retrospective case series and case-control study.

ANIMALS 16 captive cheetahs with signs of adverse reaction to oral administration of praziquantel and pyrantel, with or without oxantel embonate (affected group), and 27 cheetahs without such reactions (unaffected group), all from 3 independent facilities.

PROCEDURES Medical records and postmortem findings for affected cheetahs were reviewed and compared with those of unaffected animals. Anthelmintic doses administered, age, and sex of cheetahs were compared between groups.

RESULTS 3 reactions in affected cheetahs were fatal, whereas the remainder ranged from mild to severe. Postmortem examination failed to reveal any disease processes or conditions to explain the deaths. No differences in anthelmintic dose were identified between affected and unaffected cheetahs for all facilities combined, and no correlation existed between dose and reaction severity. No association with sex was detected, but affected cheetahs were significantly younger than unaffected cheetahs. This difference was not significant after controlling for facility.

CONCLUSIONS AND CLINICAL RELEVANCE Cheetahs were concluded to have had an adverse reaction to the praziquantel-pyrantel combination because of temporal proximity of onset of clinical signs to dose administration, similarity of signs to those reported for toxicosis in other species for these drugs, and a lack of other disease process or environmental explanatory factors. A highly cautious approach to the use of this drug combination is recommended for cheetahs.
Month of the Year Effect pada Pasar Obligasi di Indonesia
Authors: Robiyanto Robiyanto
Published: November 2017

This study examines the month-of-the-year effect on the bond returns in Indonesia. I use the monthly closing price index (Indonesia Bond Indexes / INDOBeX) data for the periods of July 2003-July 2017 from Bloomberg. I then run the Generalize Autoregressive Conditional Heteroscedasticity (GARCH) analysis technique to analyze the data because the residuals exhibit a significant pattern of Autoregressive Conditional Heteroscedasticity (ARCH). The results show that only the month of July has a significantly positive effect on the bond returns; indicating that there is the month-of-the-year effect in the Indonesian bond market. Further, these also imply that the Indonesian bond market does not exhibit a random walk pattern and consequently they are inefficient in the weak form.

Abstrak

Penelitian ini menguji pengaruh bulan-bulan perdagangan (month of the year) terhadap return obligasi di Indonesia.

Analisis data dilakukan dengan menggunakan teknik analisis Generalize Autoregressive Conditional Heteroscedasticity (GARCH) karena pola residual yang dihasilkan menunjukkan adanya pola Autoregressive Conditional Heteroscedasticity (ARCH) yang signifikan. Hasil penelitian ini menunjukan bahwa bulan Juli memiliki pengaruh positif yang signifikan terhadap return obligasi di Indonesia. Sementara bulan-bulan lainnya tidak memiliki pengaruh terhadap return obligasi di Indonesia. Hasil ini menunjukkan bahwa terjadi month of the year effect di pasar obligasi di Indonesia.

Published: November 2017

Objectives. Distal biceps tendon rupture affects the functional upper-extremity movement, impairing supination and flexion strength. According to age, profession and additional risks treatment might be nonoperative or surgical. Methods. We describe the case of a 43 years old male patient who sustained an injury to his right distal biceps and was diagnosed with acute right distal biceps rupture. Surgical treatment was decided and biceps tendon was reinserted to the radius tuberosity using a combination of a cortical button fixation associated with an interference screw. Results. Postoperative functional result was favorable with no complications and with no movement limitation after one month. Conclusions. When possible, distal biceps tendon repair should be realized surgically because this permits restoring of the muscle strength to near normal levels with no loss of motion. Nerve complications are common; therefore the surgery should be realized by experienced upper extremity surgeons.

Python is a relatively new computing language, created by Guido van Rossum [A.S. Tanenbaum, R. van Renesse, H. van Staveren, G.J. Sharp, S.J. Mullender, A.J. Jansen, G. van Rossum, Experiences with the Amoeba distributed operating system, Communications of the ACM 33 (1990) 46–63; also on-line at http://www.cs.vu.nl/pub/amoeba/, which is particularly suitable for teaching a course in computational physics. There are two questions to be considered: (i) For whom is the course intended? (ii) What are the criteria for a suitable language, and why choose Python? The criteria include the nature of the application. High performance computing requires a compiled language, e.g., FORTRAN. For some applications a computer algebra, e.g., Maple, is appropriate. For teaching, and for program development, an interpreted language has considerable advantages: Python appears particularly suitable. Python‟s attractions include (i) its system of modules which makes it easy to extend, (ii) its excellent graphics (VPython module), (iii) its excellent on line documentation, (iv) it is free and can be downloaded from the web. Python and VPython will be described briefly, and some programs demonstrated numerical and animation of some phenomenal physics. In this article, we gave solution of circle polarization by solving Maxwell equation.

Telah dilakukan penelitian untuk mengestimasi durasi rupture gempabumi yang terjadi dilautan Hindia (Aceh, Mentawai dan Jawa) yang selama ini dikenal rawan terjadi tsunami yang diakibatkan gempabumi. Kedua, untuk mengestimasi arah rupture dan lokasi-lokasi terjadinya gempa susulan. Estimasi durasi rupture gempabumi dikerjakan dengan menggunakan prosedur langsung, yaitu (1) memfilter seismogram kecepatan komponen vertikal yang direkam oleh jaringan IRIS-DMC dengan menggunakan filter Butterworth pada frekuensi tinggi (1 – 5 Hz), (2) melakukan picking waktu kedatangan gelombang P secara otomatis, (3) menentukan root mean square (RMS) dari amplitudo, (4) mengukur keterlambatan waktu kedatangan gelombang P pada 90% (T0,9), pada 80% (T0,8), pada 50% (T0,5) dan pada 20% amplitude (T0,2), dan (5) menghitung dan menampilkan hasil perhitungan durasi rupture secara cepat. Berdasarkan hasil analisis dalam riset ini dapat diketahui banwa durasi rupture gempabumi dapat diestimasi secara cepat (± 0,5 menit setelah gempa bumi terjadi) dan akurat. Selain itu, didapatkan informasi bahwa durasi rupture gempabumi memberikan informasi ekstra, yaitu jika durasi rupture gempabumi lebih besar atau sama dengan 50 detik, gempabumi tersebut berpotensi menimbulkan gempa bumi. Bahkan untuk gempabumi dengan tipe faulting-nya strike-slip bisa berpotensi menimbulkan tsunami jika durasi rupture-nya lebih besar dari 50 detik. Durasi rupture juga memberi informasi tentang arah dan panjang rupture, sehingga lokasi-lokasi yang berpeluang terjadi gempa bumi susulan dapat diestimasi.

Self-assembled In0.5Ga0.5As quantum dots (QDs) were grown using metal-organic chemical vapor deposition (MOCVD) on GaAs (100) substrate with different number of stacking QDs layers. Surface study using atomic force microscopy (AFM) shows that surface morphology of the self-assembled QDs change with different number of stacking QDs layers caused by the previous QDs layers and the thickness of the GaAs spacer layers. PL measurement shows variation in the PL spectra as a function of number of stacking layers of In0.5Ga0.5As QDs. The PL peak positions blue-shifted from 1225 nm to 1095 nm and dramatically increase in intensity with increasing number of stacking QDs layers.
KONSEKUENSI HASIL PENELITIAN TIM ICARUS TENTANG KELAJUAN NEUTRINO TERHADAP TEORI RELATIVITAS
Authors: Wikara Bertha
Published: November 2017

Penelitian ulang tim ICARUS atas kelajuan neutrino baru – baru ini mendapatkan hasil bahwa kelajuan neutrino sama dengan kelajuan cahaya. Hasil penelitian tersebut membawa konsekuensi tersendiri bagi ilmu fisika. Selama ini foton (cahaya) dianggap sebagai partikel tak bermassa, namun dalam eksperimen ICARUS ditemukan bahwa foton mempunyai kelajuan yang sama dengan neutrino yang merupakan partikel bermassa. Tidak mungkin sebuah partikel bermassa mempunyai kelajuan yang sama dengan partikel tidak bermassa. Seharusnya yang mempunyai massa lebih lambat kelajuannya dibanding yang tidak mempunyai massa. Oleh sebab itu foton seharusnya merupakan partikel yang mempunyai massa juga. Masalah lain muncul manakala rumus massa relativistik diterapkan untuk kasus neutrino. Oleh sebab neutrino mempunyai massa dan bergerak dengan kelajuan cahaya, maka nilai massa relativistiknya adalah tak terhingga. Namun ini bukan kenyataan yang dijumpai dalam eksperimen, jadi ada kesenjangan antara teori dan praktek. Cara menghilangkan kesenjangan tersebut adalah dengan menaikkan nilai konstanta c2 dalam rumus massa relativistik. Namun hal ini membuat teori relativitas memprediksi bahwa ada yang bergerak lebih cepat dari cahaya di jagad raya.

Pengambilan data dilakukan secara acak pada area seluas 0,6 km x 1 km dengan jumlah titik yang diperoleh 244 titik ukur. Proses akusisi dilakukan dengan menggunakan Magnetometer Proton ENVI SCINTREX. Pengolahan data diawali dengan koreksi IGRF dan koreksi variasi harian untuk mendapatkan anomali medan magnet total. Kemudian reduksi bidang datar, kontinuasi ke atas pada ketinggian 100 meter hingga 400 meter di atas sferoida referensi dan hasilnya digunakan untuk pemisahan anomali lokal dan regional. Hasil interpretasi kualitatif menunjukkan adanya anomali dipole magnetik di sebelah timur yang membentang dari arah barat laut ke tenggara sebesar -2125 nT hingga 1863 nT. Metode Talwani 2-D digunakan untuk interpretasi kuantitatif. Model geologi yang dihasilkan adalah patahan atau sesar. Nilai suseptibilitas magnetik di bawah kubah kawah gunung kelud sampai ke gunung lirang (k=0,0124 emu/gram) didominasi batuan basalt, dan di gunung sumbing (k=0,0234 emu/gram – 0,0239 emu/gram) yang didominasi batuan andesit.

Konsep sistem energi VHTR baik yang berbahan bakar pebble (VHTR pebble bed) maupun blok prismatik (VHTR prismatik) menarik perhatian fisikawan reaktor nuklir. Salah satu kelebihan teknologi bahan bakar bola adalah menawarkan terobosan teknologi pengisian bahan bakar tanpa harus menghentikan produksi listrik. Selain itu, partikel bahan bakar pebble dengan kernel uranium oksida (UO2) atau uranium oksikarbida (UCO) yang dibalut TRISO dan pelapisan silikon karbida (SiC) dianggap sebagai opsi utama dengan pertimbangan performa tinggi pada burn-up bahan bakar dan temperatur tinggi. Makalah ini mendiskusikan pemodelan dan perhitungan transport Monte Carlo dalam teras HTR pebble bed. HTR pebble bed adalah reaktor berpendingin gas temperatur tinggi dan bermoderator grafit dengan kemampuan kogenerasi. Perhitungan dikerjakan denganprogram MCNP5 pada temperatur 1200 K. Pustaka data nuklir energi kontinu ENDF/B-V dan ENDF/B-VI dimanfaatkan untuk melengkapi analisis. Hasil perhitungan secara keseluruhan menunjukkan konsistensi dengan nilai keff yang hampir sama untuk pustaka data nuklir yang digunakan. Pustaka ENDF/B-VI (66c) selalu memproduksi keff lebih besar dibandingkan ENDF/B-V (50c) maupun ENDF/B-VI (60c) dengan bias kurang dari 0,25%. Kisi BCC memprediksi keff hampir selalu lebih kecil daripada kisi lainnya, khususnya FCC. Nilai keff kisi BCC lebih dekat dengan kisi FCC dengan bias kurang dari 0,19% sedangkan dengan kisi SH bias perhitungannya kurang dari 0,22%. Fraksi packing yang sedikit berbeda (BCC= 61%, SH= 60,459%) tidak membuat bias perhitungan menjadi berbeda jauh. Estimasi keff ketiga model kisi menyimpulkan bahwa model BCC lebih bisa diadopsi dalam perhitungan HTR pebble bed dibandingkan model FCC dan SH. Verifikasi hasil estimasi ini perlu dilakukan dengan simulasi Monte Carlo atau bahkan program deterministik lainnya guna optimisasi perhitungan teras reaktor temperatur tinggi.

La voz apocalíptica o primera formulación del imperativo salvaje "ven"
Authors: Rodríguez Marciel Cristina
Published: November 2017

A partir de una recreación ficticia, realizada por la autora de este artículo, de algunos momentos recogidos en las más acreditadas biografías de Jacques Derrida y de Maurice Blanchot y que conciernen al relato expositivo que localiza y reconstruye las circunstancias de la amistad entre ambos, este artículo pretende, en primer lugar, constatar cómo el testimonio biográfico no puede disociarse sin resto de la ficción literaria. De ese modo, la posibilidad misma de la ficción habrá estructurado lo que se conoce como la experiencia real. La amistad conceptualizada como «gracia» procede, sin duda, de una singular experiencia personal de la amistad y ésta no podría ser vivida sin cierto soporte teórico. En segundo lugar, analizaremos cómo ese «pensar y vivir el suave rigor de la amistad», la ley de la amistad, su imperativo, es lo que va a permitir la afirmación de lo otro, el salto a la alteridad cuya primera formulación, en cuanto «imperativo salvaje», se enuncia y se anuncia a través de una voz apocalíptica que dice «ven». En prenant comme point de départ une récréation fictive, élaborée par l’auteur de cet article, de quelques moments de la vie de Jacques Derrida et de la vie de Maurice Blanchot qui ont été extraits de leurs biographies les plus renommées, nous essayons de faire un récit afin de repérer et de reconstruire les circonstances qui ont donné lieu à cette amitié. D’abord, il s’agit dans cet article de vérifier la façon dont le témoignage biographique ne peut pas se dissocier sans reste de la fiction littéraire. Ainsi la possibilité même de la fiction aura organisé ce que nous connaissons en tant qu’expérience réelle. L’amitié conceptualisée comme «grâce» provient sans doute d’une singulière expérience personnelle de l’amitié et celle-ci n’aurait pu être vécue qu’à partir d’un certain soutien théorique. Ensuite, nous analyserons la façon dont un certain «penser et vivre la douce rigueur de l’amitié» – la loi de l’amitié et son impératif – va nous permettre l’affirmation de l’autre, le saut dans l’altérité dont la première formulation, en tant qu’« impératif sauvage », s’énonce et s’annonce à travers une voix apocalyptique qui dit « viens ».
El poeta y su mito: ¿la sirena como destino del lenguaje poético? Estudio de "Sirenas", de Ángel González y Valeria Docampo
Authors: Mathios Bénédicte
Published: November 2017

Libro para niños, Sirenas (2011) es un objeto estético en el que coexisten la palabra poética de Ángel González (la publicación es póstuma) y el grafismo de Valeria Docampo. La sobriedad de las líneas, la riqueza de los colores que remiten al mundo submarino y a la noche, la aparente sencillez de la poesía polimétrica que cuenta una historia a la vez contemporánea y ancestral, reactivan suavemente el mito de las sirenas, no sin el humor y el tono provocativo que manifiesta de nuevo el poeta, dirigiéndose de hecho tanto a niños como a adultos…Este artículo analiza las dimensiones visual, sonora, narrativa, simbólica, mítica de este poema-libro emblemático, a su manera, de la obra de Ángel González. Livre pour enfants, Sirenas (2011) est un bel objet où coexistent la parole poétique d’Ángel González (publication posthume) et le graphisme de Valeria Docampo. La sobriété des lignes, la richesse des couleurs qui renvoient au monde sous-marin et à la nuit, l’apparente simplicité de la poésie polymétrique qui narre une histoire tout à la fois contemporaine et ancestrale, réactivent en douceur le mythe des sirènes, non sans l’humour et le mordant dont fait une nouvelle fois preuve le poète, s’adressant en fait aussi bien aux enfants qu’aux adultes…Cet article analyse les dimensions visuelle, sonore, narrative, symbolique, mythique, de ce poème-livre emblématique, à sa façon, de l’œuvre d’Ángel González.
Filosofía, intertextualidad y postmodernismo: la influencia de Friedrich Nietzsche en la obra novelística y en la ensayística de Juan Benet
Authors: Machin Lucas Jorge
Published: November 2017

En la obra novelística y ensayística de Juan Benet se puede detectar numerosas intertextualidades del filósofo alemán Friedrich Nietzsche que no han sido todavía adecuadamente investigadas. Entre los temas nietzscheanos que penetran la obra de Benet, los más importantes son la defensa del irracionalismo como vía de conocimiento que ayuda a explicar mejor la naturaleza de lo real, la oposición a sistemas epistemológicos cerrados, la defensa del fragmentarismo, del nihilismo, del fatalismo, el sentido de lo trágico que está presente en sus obras y en sus personajes, la dialéctica entre apolíneos y dionisiacos, el eterno retorno, la parodia del superhombre, la presencia de un sujeto descentrado por la fatalidad y por la ruina, la voluntad de poder durante la Guerra Civil española, y la preponderancia del estilo sobre el argumento. Se ofrecerán numerosos ejemplos desde su obra regionata y desde su ensayo. In the novelistic and essayistic works of Juan Benet, one can detect numerous intertextualities of the German philosopher Friedrich Nietzsche that have not yet been adequately researched. Among the Nietzschean themes in Benet, the most important are the defence of irrationalism as a way of knowledge that better explains the real, the opposition to closed epistemological systems, the defence of fragmentarism, nihilism, fatalism, the sense of tragedy that is present in his works and in his characters, the dialectic of the Apollonian and the Dionysian, the eternal return, the parody of the Superman, the presence of a subject decentered by fatality and ruin, the will to power during the Spanish Civil War, and the preponderance of style over plot. I will give many examples from Benet’s novels, above all those about Región, and from his essays.
Harold Bloom: el último cabalista
Authors: Álvarez de Morales Mercado Cristina
Published: November 2017

En este artículo abordaremos la influencia de la tradición judía a través de toda la obra bloomeana. Lo haremos a partir de tres focos de interés: la Cábala, El libro de J, y la obra de Freud y Kafka, los dos judíos más aplaudidos y estudiados por Harold Bloom. La Cábala y su estudio son uno de los pilares del judaísmo y Bloom los viene estudiando desde sus comienzos en los años 60. Bloom aborda el análisis de la Cábala siempre a partir de las interpretaciones que el cabalista Gershom Scholem hiciera de la misma. La versión de la Biblia que Harold Bloom ofrece con su Libro de J es quizá una de las más polémicas pero a la vez más originales y ricas que han aparecido en los últimos tiempos. Bloom recuerda que leer a Freud y a Kafka nos enseña que nuestra vida instintiva es agonística y que nuestros momentos más auténticos tienden a ser esos de negación, contracción y represión. This article will discuss the influence of Jewish tradition throughout Harold Bloom's work. We will do from three foci of interest: the Kabbalah, The Book of J, and the work of Freud and Kafka, the two Jews most applauded studied by Bloom. Kabbalah and its study is one of the pillars of Judaism and Bloom has been studying from his beginnings in the 60s. Bloom deals with the analysis of the Kabbalah always from the Kabbalistic interpretations by Gershom Scholem. The version of the Bible that Harold Bloom offers with his Book of J is perhaps one of the most controversial but also the most original and rich that has appeared in recent times. Bloom recalls that reading Freud and Kafka teaches us that our instinctive life is agonistic and our most authentic moments tend to be those of denial, contraction and repression.
Deconstrucción y psicoanálisis: una relación de amistad
Authors: Tornos Urzainki Maider
Published: November 2017

Desde De la grammatologie, en donde se cuestiona la primacía de la metafísica de la presencia, Derrida comprende que no puede pensar sin el psicoanálisis. Varios de sus textos lo atestiguan de manera explícita: Spéculer – sur « Freud », Le facteur de la vérité, Freud et la scène de l’écriture, Mal d’archive: une impression freudienne, Résistances –de la psychanalyse, Pour l’amour de Lacan o Les états d’âme de la psychanalyse. Así comienza una larga relación amorosa entre la deconstrucción y el psicoanálisis; un diálogo interminable, lleno de tensiones e incomprensiones recíprocas, que condicionan el pensamiento postestruturalista francés de los años sesenta. Since Of Grammatology, which questions the primacy of the metaphysics of presence, Derrida understands that he cannot think without psychoanalysis. Many of his texts attest to this in an explicit manner: Spéculer – sur « Freud », Le facteur de la vérité, Freud et la scène de l’écriture, Mal d’archive: une impression freudienne, Résistances –de la psychanalyse, Pour l’amour de Lacan or Les états d’âme de la psychanalyse. Thus begins a long love story between deconstruction and psychoanalysis; a never-ending dialogue, full of tension and mutual misunderstandings, which conditioned French poststructuralist thought in the 60s.
