[abstFig src='/00290001/11.jpg' width='300' text='Ego-noise suppression achieves speech recognition even during motion' ] This paper addresses ego-motion noise suppression for a robot. Many ego-motion noise suppression methods use motion information such as position, velocity, and the acceleration of each joint to infer ego-motion noise. However, such inferences are not reliable, since motion information and ego-motion noise are not always correlated. We propose a new framework for ego-motion noise suppression based on single channel processing using only acoustic signals captured with a microphone. In the proposed framework, ego-motion noise features and their numbers are automatically estimated in advance from an ego-motion noise input using Infinite Non-negative Matrix Factorization (INMF), which is a non-parametric Bayesian model that does not use explicit motion information. After that, the proposed Semi-Blind INMF (SB-INMF) is applied to an input signal that consists of both the target and ego-motion noise signals. Ego-motion noise features, which are obtained with INMF, are used as inputs to the SB-INMF, and are treated as the fixed features for extracting the target signal. Finally, the target signal is extracted with SB-INMF using these newly-estimated features. The proposed framework was applied to ego-motion noise suppression on two types of humanoid robots. Experimental results showed that ego-motion noise was effectively and efficiently suppressed in terms of both signal-to-noise ratio and performance of automatic speech recognition compared to a conventional template-based ego-motion noise suppression method using motion information. Thus, the proposed method worked properly on a robot without a motion information interface.*

[abstFig src='/00290001/13.jpg' width='245' text='Wayang robot' ] This paper proposes a way to protect endangered wayang puppet theater, an intangible cultural heritage from Indonesia, by turning a robot into a puppeteer successor. We developed a seven degrees-of-freedom (DOF) manipulator to actuate the sticks attached to the wayang puppet body and hands. The robot can imitate 8 distinct human puppeteer’s manipulations. Furthermore, we developed a gamelan music pattern recognition, towards a robot that can perform based on the gamelan music. In the offline experiment, we extracted energy (time domain), spectral rolloff, 13 Mel-frequency cepstral coefficients (MFCCs), and the harmonic ratio from 5 s long clips, every 0.025 s, with a window length of 1 s, for a total of 2576 features. Two classifiers (3 layers feed-forward neural network (FNN) and multi-class Support Vector Machine (SVM)) were compared. The SVM classifier outperformed the FNN classifier with a recognition rate of 96.4% for identifying the three different gamelan music patterns.

[abstFig src='/00290001/19.jpg' width='300' text='Human-voice enhancement system for a hose-shaped robot' ] This paper presents the design and implementation of a two-stage human-voice enhancement system for a hose-shaped rescue robot. When a microphone-equipped hose-shaped robot is used to search for a victim under a collapsed building, human-voice enhancement is crucial because the sound captured by a microphone array is contaminated by the ego-noise of the robot. For achieving both low latency and high quality, our system combines online and offline human-voice enhancement, providingan overview first and then details on demand. The online enhancement is used for searching for a victim in real time, while the offline one facilitates scrutiny by listening to highly enhanced human voices. Our online enhancement is based on an online robust principal component analysis, and our offline enhancement is based on an independent low-rank matrix analysis. The two enhancement methods are integrated with Robot Operating System (ROS). Experimental results showed that both the online and offline enhancement methods outperformed conventional methods.

[abstFig src='/00290001/21.jpg' width='300' text='Spatial distribution pattern of the observed birds and localized sounds' ] This paper reports the results of our field test of HARKBird, a portable system that consists of robot audition, a laptop PC, and omnidirectional microphone arrays. We assessed its localization accuracy to monitor songs of the great reed warbler (Acrocephalus arundinaceus) in time and two-dimensional space by comparing locational and temporal data collected by human observers and HARKBird. Our analysis revealed that stationarity of the singing individual affected the spatial accuracy. Temporally, HARKBird successfully captured the exact song duration in seconds, which cannot be easily achieved by human observers. The data derived from HARKBird suggest that one of the warbler males dominated the sound space. Given the assumption that the cost of the singing activity is represented by song duration in relation to the total recording session, this particular male paid a higher cost of singing, possibly to win the territory of best quality. Overall, this study demonstrated the high potential of HARKBird as an effective alternative to the point count method to survey bird songs in the field.

[abstFig src='/00290001/23.jpg' width='300' text='Calling behavior of a male Japanese Tree Frog' ] Sensing the external environment is a core function of robots and autonomous mechanics. This function is useful for monitoring and analyzing the ecosystem for our deeper understanding of the nature and accomplishing the sustainable ecosystem. Here, we investigate calling behavior of male frogs by applying audio-processing technique on multiple audio data. In general, male frogs call from their breeding site, and a female frog approaches one of the males by hearing their calls. First, we conducted an indoor experiment to record spontaneous calling behavior of three male Japanese tree frogs, and then separated their call signals according to independent component analysis. The analysis of separated signals shows that chorus size (i.e., the number of calling frogs) has a positive effect on call number, inter-call intervals, and chorus duration. We speculate that a competition in a large chorus encourages the male frogs to make their call properties more attractive to conspecific females.

Market Dependency and Household Food Consumption in East Java, Indonesia
Authors: Lokollo Erna Maria
Published: February 2017

ABSTRAK

Tujuan utama penelitian ini adalah untuk melihat perbedaan diantara konsumen di daerah pedesaan dan perkotaan dalam mengkonsumsi bahan makanan utama, dan terutama menelusuri seberapa jauh konsumsi di masing-masing lokasi (desa dan kota) tergantung pada uang tunai dan pasar (cash or market dependency) untuk pemenuhan konsumsi bahan makanan tersebut. Data dianalisis dari SUSENAS 1993, BPS, Provinsi Jawa Timur. Hasil penelitian menunjukkan bahwa ketergantungan akan uang tunai dan pasar berhubungan erat dengan jumlah konsumsi bahan makanan yang akan dibeli. Terdapat perbedaan nyata antara konsumen di daerah pedesaan dan perkotaaan, dimana konsumen di pedesaan memiliki angka ketergantungan uang tunai dan pasar yang lebih rendah daripada konsumen di perkotaan. Asumsi lama dan klasik yang menyatakan bahwa penduduk di pedesaan kebanyakan adalah petani subsisten (yang dapat memproduksi untuk dikonsumsi sendiri) sudah tidak berlaku lagi. Walaupun demikian masih didapati bahwa seringkali rumahtangga di pedesaan menjual bahan makanan berkualitas lebih baik yang diproduksinya, sehingga uang hasil penjualan tersebut dapat digunakan untuk  membeli kualitas yang lebih rendah, yang berarti memaksimumkan konsumsi dari segi kuantitas. Hasil penelitian ini menyiratkan pentingnya pengambil keputusan menyadari perbedaan antara penduduk desa dan kota tersebut. Studi semacam ini apabila ditunjang oleh studi perilaku marketed dan marketable surplus dapat membantu pembuat kebijaksanaan di bidang pengadaan dan distribusi pangan. Studi ini juga membantu memperjelas adanya perilaku ketergantungan pada uang tunai dan pasar yang berbeda pada rumahtangga di daerah desa dan perkotaan.
Subsektor Perikanan dan Kehandalan Ekspor Tuna/Cakalang di Sulawesi Utara: Analisis Biaya­ Manfaat Sosial
Authors: Hutabarat Budiman , Sayaka Bambang
Published: February 2017

ABSTRAK

Makalah ini ditujukan untuk mengkaji keragaan dan sumbangan kegiatan perikanan tangkap terhadap perekonomian dan masyarakat Sulawesi Utara dengan melakukan analisis tujuan dan pasar ekspor, serta analisis daya saing dan mengkaji kendala pengembangan ekspornya. Penelitian dilakukan pada bulan Juli 1999 sampai Maret 2000 dengan mengumpulkan data primer dan sekunder melalui wawancara kepada nelayan, juragan/pemilik kapal, pengolah/pengekspor ikan. Makalah ini menyimpulkan antara lain ekspor hasil perikanan Provinsi Sulawesi Utara didominasi oleh produk ikan beku, segar, kaleng, dan kering atau ikan kayu. Tujuan utama ekspor hasil perikanan Sulawesi Utara terbatas pada enam negara di dunia yaitu Jepang, Amerika Serikat, lnggris, Korea, Filipina, dan Taiwan. Ekspor hasil perikanan Sulawesi Utara yang utama ke Jepang adalah tuna segar dan beku, tuna kaleng, ikan kering/kayu, layang beku; ke Amerika Serikat atau ke lnggris adalah tuna kaleng dan skipjack kaleng. Usaha penangkapan ikan di Sulawesi Utara sangat efisien jika dibandingkan dengan harga dunia. Efisiensi usaha atau nisbah biaya-manfaat sosial penangkapan ikan mencapai 64 persen. Namun, meskipun keunggulan komparatif ini sangat nyata, keunggulan ini masih belum dapat ditingkatkan menjadi keunggulan kompetitif karena berbagai faktor antara lain; kapal­-kapal yang beroperasi di perairan pantai kurang dari 12 mil sudah terlalu banyak, dan sistem tata niaga tidak kokoh. Untuk mengatasi hal ini, pemerintah daerah Tingkat I Provinsi Sulawesi Utara perlu membuat rencana yang tersusun dengan baik, demikian pula pemerintah daerah tingkat II untuk mewujudkan program otonomi daerah yang telah digulirkan pada waktu lalu. Bidang-bidang yang perlu mendapat perhatian adalah peningkatan sarana dan prasarana, insentif untuk investasi, dan insentif untuk pengem­bangan tujuan ekspor dan produk baru. Pada saat yang sama pengawasan yang ketat untuk pelanggar aturan dan penindakan pengusaha yang tidak memiliki izin harus ditempuh.
Econometric Analysis of the Impact of Domestic Rice Procurement Policy on Producer Price: The Case of Rice in Bangladesh
Authors: Ashraf Mohammad A.
Published: February 2017

Tulisan ini mempelajari secara teoritis dan praktek dari dampak kebijakan pemerintah terhadap penetapan harga gabah pada tingkat petani di Bangladesh. Pada dasarnya, kebijakan ini berupaya mencapai produksi beras dan gandum pada level harga yang ditetapkan dalam upaya memproteksi pendapatan petani dengan menstabilkan harga-harga pangan dan menyediakan pangan untuk kelompok-kelompok konsumen tertentu baik pada kondisi normal maupun tidak. Studi ini melakukan analisis ekonometrik yang menggunakan data series sepanjang 25 tahun yang dikumpulkan dari instansi pemerintah dan swasta. Hasil empirik menunjukkan bahwa petani padi tidak memperoleh keuntungan dari kebijakan ini, bahkan dalam jangka pendek sekalipun, karena adanya kesalahan potensial dari model teoritis dan pelaksanaannya. Dampaknya, intervensi pemerintah dalam upaya menjamin ketahanan pangan di masa mendatang perlu dikaji ulang untuk menetarpkan target-target yang obyektif.
Uncertainties in Global Warming Temperature-Trend and Their Impacts on Agricultural Production: an Econometric Evaluation
Authors: Ashraf Mohammad A.
Published: February 2017

Makalah ini membahas kecenderungan dampak pemanasan global yang terjadi akhir-akhir ini. Estimasi dilakukan dengan parameter fraksional dari catatan relatif panjang menggunakan tehnik outlier aditif sebagai pengamatan bebas yang dihasilkan di atmosfer karena pemanasan global. Selanjutnya penelitian ini mengamati secara empiris dampak pemanasan global terhadap aspek tertentu produksi pertanian global. Berdasarkan simulasi Monte Carlo, proses menghasilkan data diterapkan dimana outlier aditif dihasilkan melalui cara discrete atau tidak kontinyu. Hasil observasi menunjukkan bahwa outlier aditif mempengaruhi bias dan MSE parameter fraksional estimasi. Ukuran outlier aditif dalam proses menghasilkan data juga memiliki pengaruh penting terhadap parameter farksional estimasi yang tergantung pada nilai parameter fraksional yang sebenarnya. Hasilnya menunjukkan variabilitas non tren atau siklus alami yang dipengaruhi oleh proses stokastik dalam hal sifat perubahan iklim dengan observasi bebas (outlier) yang menghasilkan outcome berlawanan dari ketidakpastian yang intensif terhadap tren data temperatur dunia pada kondisi riil. Hasil pengamatan empiris menyimpulkan bahwa pada akhir abad 21 secara meyakinkan pemanasan global akan mempunyai dampak negatif terhadap agregat produksi pertanian global dan dampaknya bisa sangat parah jika manfaat fertilizasi karbon (peningkatan hasil dalam lingkungan yang kaya karbon) tidak tampak, terutama jika kelangkaan air membatasi irigasi. Lagi pula, jika pemasan global tidak berhenti pada tahun 2080, tetapi temperatur global terus meningkat pada abad 22, kegagalan produksi pertanian bisa semakin parah. Studi ini juga menunjukkan bahwa akumulasi pengaruh produksi pertanian kemungkinan lebih serius bagi negara berkembang dengan kerugian terbesar di Afrika, Amerika Latin, dan India.
Dampak Intervensi Pemerintah terhadap Kinerja Ekonomi Komoditas Perkebunan Utama pada Berbagai Rezim Nilai Tukar Rupiah 1979-2005
Authors: Dradjat Bambang
Published: February 2017

Penelitian ini difokuskan pada dampak dari kebijakan pemerintah di bidang produksi, perdagangan dan makro ekonomi terhadap harga riil, tingkat proteksi dan kinerja komoditas utama perkebunan, yaitu kakao, kopi, karet, teh, dan minyak kelapa sawit mentah (CPO) di pasar domestik. Metode analisis yang digunakan adalah dekomposisi harga komoditas utama perkebunan di pasar domestik dan perhitungan tingkat proteksi langsung, tak langsung dan total keduanya. Hasil penelitian menunjukkan bahwa harga riil komoditas perkebunan pada periode 1985-1997 menunjukkan penurunan dibandingkan pada periode 1979-1985. Pada periode 1997-2005, harga riil kakao dan karet menunjukkan kenaikan dibandingkan periode sebelumnya.  Namun, hal ini tidak terjadi untuk kopi, teh dan minyak kelapa sawit. Secara umum, tingkat proteksi tidak langsung menunjukkan kenaikan, sebaliknya tingkat proteksi langsung mengalami penurunan.  Secara total, tingkat proteksi masih positif walaupun mengalami penurunan dari waktu ke waktu. Nilai tukar perdagangan komnoditas utama perkebunan terhadap komoditi impor, sebagai contoh gula, dari tahun 1979 ke 1997 mengalami penurunan tetapi masih bernilai positif.  Penurunan kinerja ini lebih nyata jika dilihat dari kapasitas untuk mengimpor. Pada masa mendatang pemerintah Indonesia sebaiknya menyesuaikan intervensinya secara terus menerus.  Pergerakan harga internasional komoditas utama perkebunan perlu diperhitungkan sehingga intervensi tersebut dapat menghasilkan insentif bagi produsen dan pengekspor untuk berproduksi dan mengekspor.

Authors: Kutsiyah Farahdilla , Mustadjab Muslich , Anindita Ratya , Yustika Ahmad Erani
Published: February 2017

Artikel ini menganalisis kinerja program bantuan pinjaman langsung masyarakat (BPLM) yang disalurkan melalui lembaga pesantren. Pendekatan teori ekonomi kelembagaan digunakan untuk menganalisis kinerja program ini, yang mencakup partisipasi kontrak, modal sosial, biaya transaksi, dan pendapatan. Penelitian ini dilaksanakan pada dua pesantren di Pulau Madura. Pengambilan contoh menggunakan metode cluster random sampling. Hasil penelitian menunjukkan bahwa modal sosial pesantren adalah tata nilai barokah, kepatuhan, jujur, dan jaringan yang solid antara petani dan pesantren. Modal sosial tersebut mengakar dalam kehidupan petani dan mempengaruhi pelaksanaan kegiatan ekonomi pesantren. Sementara, biaya transaksi petani dalam pelaksanaan BPLM tergantung pada operasional kelembagaan masing-masing pesantren, yang disebabkan oleh perbedaan struktur tata kelola, perilaku petani/ketua kelompok, jaringan pesantren, dan ketidakpastian. Adapun  biaya eksekusi  memberi kontribusi yang paling tinggi terhadap total  biaya transaksi. Kenaikan  biaya transaksi ini akan diikuti dengan penurunan secara nyata  pendapatan petani.

Актуальність. Атеротромботичний підтип ішемічного інсульту становить 50 % випадків захворювання та є причиною інвалідизації працездатного населення середнього віку. Судинні порушення можуть бути пов’язані зі змінами у структурі генів ангіотензинперетворюючого ферменту (АСЕ), ангіотензиногену (AGT) та бета-фібриногену (FGB). Мета дослідження. Дослідити зв’язок наявності I/D (rs1799752) поліморфізму гена АСЕ, Т174М (rs4762) поліморфізму гена AGT та С-148Т (rs1800787) поліморфізму гена FGB із ризиком раннього розвитку ішемічного інсульту атеротромботичного підтипу в популяції осіб білої раси, які проживають на території України. Матеріали та методи. Генетичний аналіз було проведено 78 хворим (24 жінки, 54 чоловіки), які перенесли ішемічний інсульт, та 55 особам популяційного контролю (20 жінок, 35 чоловіків), які не мали тяжких серцево-судинних захворювань. Середній вік пацієнтів експериментальної групи становив 53,9 ± 9,43 року, групи контролю — 59,8 ± 14,8 року. Поліморфізми генів AGT та FGB досліджували методом полімеразної ланцюгової реакції з подальшою рестрикцією ампліфікованих фрагментів. Генотипування поліморфізму I/D гена АСЕ було проведено методом алель-специфічної полімеразної ланцюгової реакції. Результати. Дослідження ризику розвитку захворювання показало, що носії I/D- та DD-генотипу гена АСЕ мають менший ризик захворіти на ішемічний інсульт атеротромботичного підтипу, ніж носії I/І-генотипу (OR = 0,303, 95% CI 0,134–0,688; р < 0,05, та OR = 0,303, 95% CI 0,134–0,688; р < 0,05 відповідно). Носії поліморфного генотипу -148СТ гена FGB частіше ніж удвічі ризикують захворіти на ішемічний інсульт (OR = 2,452; 95% CI 1,201–5,005; р < 0,05), ніж носії генотипу -148СС. Зв’язок поліморфізму гена AGT T174M із ризиком розвитку ішемічного інсульту був відсутній. Висновки. Поліморфний генотип -148С/Т гена FGB, а також алель І та генотип ІІ гена АСЕ є факторами ризику раннього розвитку ішемічного інсульту атеротромботичного підтипу в популяції осіб, які проживають на території України.

This paper proposes a methodology based on system connections to calculate its complexity. Two study cases are proposed: the dining Chinese philosophers’ problem and the distribution center. Both studies are modeled using the theory of Discrete Event Systems and simulations in different contexts were performed in order to measure their complexities. The obtained results present i) the static complexity as a limiting factor for the dynamic complexity, ii) the lowest cost in terms of complexity for each unit of measure of the system performance and iii) the output sensitivity to the input parameters. The associated complexity and performance measures aggregate knowledge about the system.

The bronze signum from Timacum Maius and its cultic attribution
Authors: Petrovic Vladimir , Filipovic Vojislav
Published: February 2017

The bronze signum discussed in this paper was discovered by archaeological
ex?cavation on the site of Timacum Maius in 2010. Found in the area of a
luxurious Roman-period building, the artefact shows a tapering body with a
central conical socket similar to a spearhead socket. It is one of the
twenty-three known signa of the so-called classical-type. Most of them were
found in the context of the cult of Jupiter Dolichenus, and we also presume
the cultic purpose of the bronze signum from Timacum Maius. A similar find
comes from Jupiter Dolichenus? shrine in Egeta on the Danube limes with an
inscription that connects it directly with the Dolichenian cult, and with the
First Cohort of Cretans (Cohors I Cretum), the unit which had previously been
stationed at Timacus Maius. The signum from Timacum Maius is most likely also
connected with the cult of Jupiter Dolichenus and chronologically belongs to
a period which is much earlier than the Severan age.
Grand Zupan Uros II of Rascia
Authors: Kalic Jovanka
Published: February 2017

Historical data on the person and policies of the ?veliki [grand] zupan? Uros
II - archzupan in Byzantine sources, magnus comes in Latin texts - can be
found in twelfth-century Serbian, Greek, Hungarian, German and Russian
sources. The paper is divided into three sections dealing specifically with
Uros II?s family relations (ancestors and descendants); chronological issues
of his reign in Serbia; and his domestic and foreign policies. Uros II?s
father, the Serbian zupan Uros I, had three sons and a daughter: Uros II,
Desa, Belos and Helen (Jelena). Uros II succeeded his father as the ruler of
Serbia. Helen married king B?la II of Hungary (1131-41) and became a very
influential figure at the Hungarian court. Their brother Belos, who was known
in Hungary as ban B?la and sub?sequently held the office of the palatine of
Hungary, considerably contributed to the firming up of Serbian-Hungarian
political ties. Based on a detailed analysis of the surviving sources, the
author suggests the conclusion that Uros II was a true predecessor of Stefan
Nemanja in all his policies. He was a vassal of the Byzantine emperor but he
allied with Hungary in the aspiration to achieve independence. At the time of
Uros II and his successors the region of Rascia (Raska, Rassa), known for
the city of Ras (modern Novi Pazar) and the Bishopric of Raska with the
bishop?s seat at the church of Sts Peter and Paul, was the core of the
Serbian state.
Similarities and differences in imperial administration Great Britain in Egypt and Austria-Hungary in Bosnia-Herzegovina 1878-1903
Authors: Nikolic Anja
Published: February 2017

This article discusses the similarities and differences of the position of
Great Britain in Egypt and Austria-Hungary in Bosnia-Herzegovina in the age
of New Imperialism. Comparative approach will allow us to put both situations
in their historical context. Austria-Hungary?s absorption of
Bosnia-Herzegovina was part of colonial involvement throughout the world.
Egypt and Bosnia-Herzegovina were formally parts of the Ottoman Empire,
although occupied and administrated by European Powers. Two administrators,
Evelyn Baring as consul-general in Egypt and Benjamin von K?llay as civil
administrator of Bosnia-Herzegovina, believed that it was their duty to bring
?civilization?, prosperity and western culture to these lands - a classic
argumentation found in the New Imperialism discourse. One of the most
important tasks for both administrators was fighting the national movements,
which led to the suppression of political freedoms and the introduction of a
large administrative apparatus to govern the newly-occupied lands. Complete
control over political life and the educational system was also one of the
major features of both administrations. Both Great Britain in Egypt and
Austria-Hungary in Bosnia-Herzegovina never tackled the agrarian question for
their own political reasons. British rule in Egypt and Austro-Hungarian in
Bosnia-Herzegovina bore striking resemblances.
Literature on music in the Southslavic Choral Union Herald (1935-1938)
Authors: Vasic Aleksandar
Published: February 2017

During 1935, 1936. and 1938, in Belgrade was published a monthly magazine The
Southslavic Choral Union Herald [Vesnik Juznoslovenskog pevackog saveza].
Three years represent 16 issues or 119 articles, or 216 pages. The first
editor was Milenko Zivkovic (1901-1964), a Serbian composer of the younger
generation, the chief secretary of the Southslavic Choral Union. The magazine
was conceived as a newsletter. Choral societies, members of the South Slavic
Choral Association, were given the opportunity to stay informed about the
work of the Union and the activities of choral societies throughout the
Kingdom of Yugoslavia. Therefore, Herald published numerous news, informative
articles, speeches and obituaries. However, the Herald got physiognomy of a
music magazine thanks to essays on the significant figures of Serbian music
(Davorin Jenko, Stevan Mokranjac), texts about the problems of choral
technique and interpretation, critical reviews of sheet music, and musical
criticism. These texts were written by the leading Serbian musicians of the
time: Milenko Zivkovic, Branko Dragutinovic, Petar Krstic, Mihailo
Vukdragovic, Miloje Milojevic and Richard Schwartz. The Herald represented
the ideology of integral Yugoslavism. The assassination of Yugoslav king
Alexander Karadjordjevic during his visit to Marseilles in 1934 strongly
affected the Kingdom of Yugoslavia, which has long been in the political
crisis. However, the Herald and the Southslavic Choral Union have remained
faithful to the ideology of Yugoslavism and to King Alexander as its symbol.
Betavoltaic performance under extreme temperatures
Authors: Adams Tom , Revankar Shripad , Cabauy Peter , Elkind Bret , Cheu Darrell
Published: February 2017

Longevity of sensors and portable devices is severely limited by temperature,
chemical instability, and electrolyte leakage issues associated with
conventional electrochemical batteries. Betavoltaics, which operate similar
to photo voltaics, can operate in a wide temperature range safely without
permanent degradation. Though not a new concept, which began in the 1950's
and peaked in the mid 1970's, research has been minimal and sporadic until
recent advancements in ultra-low power electronics and materialization of low
power applications. The technology is rapidly maturing, generating research,
and development in increasing the beta emitting source and semiconductor
efficiencies. This study presents an update on betavoltaic technology,
results from temperature evaluation on commercially available General
Licensed betavoltaic cells, development of a hybrid system for latent and
burst power, modeling and simulation techniques and results, and current and
proposed research and development. Betavoltaic performance was successfully
demonstrated for a wide temperature range (-30?C to 70?C). Short circuit
current and open circuit voltage were used to compare electrical performance.
Results indicate that the open-circuit voltage and maximum power decreased as
temperature increased due to increases in the semiconductor's intrinsic
carrier concentration.
Study of the alternative elution agent for the DIPHONIX resin
Authors: Kanka Lukas , Janda Jiri
Published: February 2017

The work was focused on the experimental determination of the
separation-extraction properties of solid extrahent DIPHONIX (Eichrom
Industries, USA) depending on the used eluent. Extraction properties were
tested for plutonium, americium, curium, and uranium. The used mobile phases
were hydrochloric acid and nitric acid at various concentrations. The aim was
to find the most appropriate combination of mobile phase and eluent, which
would lead to the highest possible yield. The most commonly used eluent
published in literature is 1-hydroxyethane 1, 1-diphosphonic acid (HEDP,
Etidronic Acid). Based on the research the specific compounds were selected
which are generaly known for their complexing properties, such as the salts
of oxalic acid and citric acid at different concentrations. Activities of the
samples obtained by elution were measured by liquid scintillation
spectrometry.
GROWTH PERFORMANCE AND COCOON PRODUCTION OF SILKWORM (Bombyx mori L) ON DIFFERENT FREQUENCY OF FEEDING AND AGE OF LEAVES
Authors: Widiyaningrum Priyantini
Published: February 2017

The aim of this study was to evaluate the effects of different frequency feeding and aging of leaves on increasing weight of silkworm instar IV-V and cocoon production. The research was conducted in Cultivation Center of Silkworm Candiroto, Temanggung. The research design was Factorial Design with three level of age from the leaves (the third – fourth leaves from tip of leaf; fifth-sixth leaves from tip of leaf; sevent-eight leaves from tip of a leaf, and three level of feeding frequency 3, 4, 5 times/day). The parameter observed were average daily gain (ADG), weight of cocoon, and weight of empty cocoon. The data gained were analyzed by analysis of variance and to find out the difference caused on the treatments, Duncan Multiple Range Test was used. It is concluded that the different frequency of feeding and age of leaves is significant (P less than 0.05) in ADG of silkworm and weight of empty cocoon. The seventh- eight leaf from tip of a leaf, and frequency of feeding five times/day resulting ADG and empty cocoon of the best.

Fostering conversations (and even better, interdisciplinary collaborations)
between mobility historians and media historians is a high priority for this
journal. Three years ago in Transfers 3, no. 1 (spring 2013), Dorit Müller and
Heike Weber, as editors of this journal and guest editors of a Special Section
on Media and Mobility, made a plea to study “the intense correlations between
media and transport technologies,” which had been fatefully split at
the end of the nineteenth century. On that occasion, we also announced a
“portfolio” on Media and Mobility (for more details, see this journal’s website),
which was designed to stimulate the writing and publication of such
crossover scholarship. We wait in hope for a courageous and curious historian
who ventures an analysis of the car as a medium of communication, to name
just one possible example.
Interplaced Mobility in the Age of “Digital Gestell”
Authors: Howard Christopher , Küpers Wendelin
Published: February 2017

The following article explores meanings and implications of mobile technologies
and embodiment in a globally networked context. Drawing on ethnographic
research on global travelers moving through Nepal and India, we
focus on the role mobile technologies play in mediating perceptions and
performances of place. Facilitated by contemporary media and mobility infrastructures,
we suggest that mobile subjects are relationally “interplaced.”
By introducing this notion, we aim to illustrate how forms of virtual mobility
overlap with and impact actual, corporeal experience. Following Heidegger,
we also develop a concept we call “digital Gestell” (enframement). Applying
Heidegger’s reflection that technologies of a given historical epoch frame the
way subjects approach the world, we can say that many people today are “digitally
enframed.” Facing this increasingly technologized Being-in-the-world,
we suggest an “ethos of Gelassenheit” for a more responsive and responsible
awareness of the powers technologies hold on our perceptions and actions.
Mobile Representations of a “New Pacific”
Authors: Steel Frances
Published: February 2017

This comment reflects on the contributions to this special section on print
culture and mobility in the Pacific. It focuses on the ways in which changing
attitudes toward ocean-going mobility and its mass commercialisation in the
fi rst half of the twentieth century encouraged new textual and visual forms of
appraisal and representation of the Pacific. This, in turn, facilitated the fashioning
of new mobile subjectivities, which illuminate a range of gendered and
racialized aspirations being projected into the Pacific region from the white
settler states around its rim. Together, the articles suggest avenues for further
research on the impact of shipboard and island port encounters on forms of
Australian self-presentation and engagement in the region.
Analysis of saccular aneurysms in the Barrow Ruptured Aneurysm Trial

Published: February 2017

OBJECTIVE

The Barrow Ruptured Aneurysm Trial (BRAT) is a prospective, randomized trial in which treatment with clipping was compared to treatment with coil embolization. Patients were randomized to treatment on presentation with any nontraumatic subarachnoid hemorrhage (SAH). Because all other randomized trials comparing these 2 types of treatments have been limited to saccular aneurysms, the authors analyzed the current BRAT data for this subgroup of lesions.

METHODS

The primary BRAT analysis included all sources of SAH: nonaneurysmal lesions; saccular, blister, fusiform, and dissecting aneurysms; and SAHs from an aneurysm associated with either an arteriovenous malformation or a fistula. In this post hoc review, the outcomes for the subgroup of patients with saccular aneurysms were further analyzed by type of treatment. The extent of aneurysm obliteration was adjudicated by an independent neuroradiologist not involved in treatment.

RESULTS

Of the 471 patients enrolled in the BRAT, 362 (77%) had an SAH from a saccular aneurysm. Patients with saccular aneurysms were assigned equally to the clipping and the coiling cohorts (181 each). In each cohort, 3 patients died before treatment and 178 were treated. Of the 178 clip-assigned patients with saccular aneurysms, 1 (1%) was crossed over to coiling, and 64 (36%) of the 178 coil-assigned patients were crossed over to clipping. There was no statistically significant difference in poor outcome (modified Rankin Scale score > 2) between these 2 treatment arms at any recorded time point during 6 years of follow-up. After the initial hospitalization, 1 of 241 (0.4%) clipped saccular aneurysms and 21 of 115 (18%) coiled saccular aneurysms required retreatment (p < 0.001). At the 6-year follow-up, 95% (95/100) of the clipped aneurysms were completely obliterated, compared with 40% (16/40) of the coiled aneurysms (p < 0.001). There was no difference in morbidity between the 2 treatment groups (p = 0.10).

CONCLUSIONS

In the subgroup of patients with saccular aneurysms enrolled in the BRAT, there was no significant difference between modified Rankin Scale outcomes at any follow-up time in patients with saccular aneurysms assigned to clipping compared with those assigned to coiling (intent-to-treat analysis). At the 6-year follow-up evaluation, rates of retreatment and complete aneurysm obliteration significantly favored patients who underwent clipping compared with those who underwent coiling.

Alternating electric tumor treating fields for treatment of glioblastoma: rationale, preclinical, and clinical studies
Authors: Mittal Sandeep , Klinger Neil V. , Michelhaugh Sharon K. , Barger Geoffrey R. , Pannullo Susan C. , Juhász Csaba
Published: February 2017

OBJECTIVE

Treatment for glioblastoma (GBM) remains largely unsuccessful, even with aggressive combined treatment via surgery, radiotherapy, and chemotherapy. Tumor treating fields (TTFs) are low-intensity, intermediate-frequency, alternating electric fields that have antiproliferative properties in vitro and in vivo. The authors provide an up-to-date review of the mechanism of action as well as preclinical and clinical data on TTFs.

METHODS

A systematic review of the literature was performed using the terms “tumor treating fields,” “alternating electric fields,” “glioblastoma,” “Optune,” “NovoTTF-100A,” and “Novocure.”

RESULTS

Preclinical and clinical data have demonstrated the potential efficacy of TTFs for treatment of GBM, leading to several pilot studies, clinical trials, and, in 2011, FDA approval for its use as salvage therapy for recurrent GBM and, in 2015, approval for newly diagnosed GBM.

CONCLUSIONS

Current evidence supports the use of TTFs as an efficacious, antimitotic treatment with minimal toxicity in patients with newly diagnosed and recurrent GBM. Additional studies are needed to further optimize patient selection, determine cost-effectiveness, and assess the full impact on quality of life.
Expected service lives and depreciation profiles for capital assets: Evidence based on a survey of Norwegian firms
Authors: Barth Nini , Cappelen Ådne , Skjerpen Terje , Todsen Steinar , Åbyholm Thom
Published: February 2017

This paper presents results from a survey of Norwegian firms on their perception of expected economic service life of various fixed capital assets as well as their assessment of depreciation profiles. An econometric analysis for two types of capital assets, where second hand markets and prices are available, shows that expected service life for Machinery and equipment for mining and manufacturing is estimated to be between 9 and 10 years. For Tools, instruments, furnishings etc. the expected service life is estimated to be 8 years. These results are in line with a descriptive analysis of the survey and they are also quite similar to those found in the existing literature. Results from this study have been used in a revision of the Norwegian national accounts.
Topical application of hemostatic paste

Published: February 2017

As a measure to control minor surgical bleeding, surgeons usually depend on a number of hemostatic aids. Topical use of bovine thrombin is a widely used procedure to arrest such minor bleeding. A 35 year old male sergeant of Bangladesh Air Force presented with repeated development of hematoma in his left thigh without any history of trauma or previous history of bleeding. Critical analysis of the patients history, routine and sophisticated hematological investigations revealed that the patient developed anti-thrombin antibody following the application of hemostatic paste in the tooth socket five years back during minor dental procedure to stop ignorable bleeding episodes. Therefore, topical use of hemostatic glue/paste or bovine thrombin should be avoided to desist minor bleeding as recombinant human thrombin is now available for topical use.
