    Full Text Available Biometrics is a method of recognition of an identity based on human physical characteristics such as the face, fingerprint, hand geometry, retina, and voice. Biometric identification that commonly used is the fingerprint recognition. Fingerprint identification process can be accelerated by reducing the number of fingerprint comparisons, splitting fingerprint databases into a number of classes based on pre-defined classes, such as fingerprint patterns. Fingerprint patterns are divided into five categories: Whorls, Right Loops, Left Loops, Arch, and Tented Arch. One of the pattern recognition techniques (fingerprint is using neural network. This research developed a RBF (Radial Basis Function neural network, which is known as SLFNs (Single Hidden Layer Feed-forward Neural Networks that reliable in pattern recognition. The use of ELM (Extreme Learning Machine algorithm on RBF network is an alternative to avoid long computation in the absence of adjustment weights during the training process so that the computing time relatively short. OLS (Orthogonal Least Square is used to optimize the weights and RBF network simplification. The preprocessing of fingerprint images are grayscalling, histogram equalization, and image sequences block operation. Feature extraction method that used based on the orientation of the dominant direction of the image. One fingerprint image is represented by a value of 256 dominant angle in radians unit. From the results indicate that the ELM-RBF and OLS system can recognize fingerprint patterns with 100% accuracy on the training process, and 60% accuracy in the testing process. Keywords: Fingerprint Pattern Recognition, Extreme Learning Machine, Radial Basis Function, Orthogonal Least Square Biometrik merupakan metode pengenalan identitas seseorang berdasarkan karakteristik fisik manusia misalnya wajah, sidik jari, struktur telapak tangan, letak retina mata, dan suara.

    Soil gas and indoor radon concentrations have been measured around Jari in Parvati Valley, Himachal Pradesh, India, to study their relationship with the local geology. Both soil gas and indoor radon concentrations were found to be higher near structurally controlled uranium mineralization. Indoor radon levels in the houses of the study area are considerably higher than the ICRP recommended value of 200 Bq m -3 . The high indoor radon concentration found may be attributed to the geology of the area. This area needs more detailed investigation as it may be one of the areas of high radon risk in India.

    Full Text Available The objective of this paper is to raise reflections on the social and environmental issues of the city of Laranjal do Jari from the point of view of its residents who are taking part in this survey. It regards a city located in the frontier area, south of the state of Amapá, that concentrates 94,9%  of the county’s population, constituted by 39.942 inhabitants. Living in such city means to live with perverse heritages induced by the installation of Jari Project, in the region, in the 70’s – a time from which a number of residents live in stilt houses over the waters of the Jari River, whose structure is that of a extended pluvial slum. The city lives with grave social and environmental issues, which, historically, have naturalized themselves to the life of the inhabitants, related to garbage, water, sewage, housing, among others, which ratify the poverty index in the order of 46,2% and are highlights in the urban configuration. The research was of qualitative nature, realized with 48 city residents, field experiments were developed inspired on the Culture Circle, from Paulo Freire. The results indicate that, when it is about proposing changes in the built environment, it is fundamental to summon those who know the reality in which he lives.

     Media sosial, seperti namanya, adalah media bagi masyarakat untuk bersosialisasidengan orang lain tanpa dibatasi ruang dan waktu melalui jaringan internet. Salah satu bentuk media sosial yang paling banyak digunakan saat ini, terutama oleh masyarakat Indonesia, adalah jejaring sosial Facebook. Masyarakat Indonesia melakukan banyak kegiatan di situs jejaring sosial tersebut, seperti mengunggah tulisan dan berkomentar pada suatu unggahan. Salah satu fitur yang digemari di Facebook adalah fitur bagikan yang berfungsi agar pengguna dapat membagi tautan dari orang lain keakun pribadi mereka dengan pengaturan tertentu. Adanya kemudahan dalam menggunakan fitur bagikan tersebut, ternyata malah menimbulkan banyak kasus. Kasus ungkapan kemarahan pemain bulutangkis asal Denmark terhadap ancaman pembunuhan yang ditujukan kepada mereka, hingga kasus penghinaan Presiden Indonesia menjadi contoh nyata dari efek fitur tersebut. Tidak jarang masalah yang ada di jejaring sosial berujung pada hukuman sosial,bahkan dapat masuk dalam ranah hukum pidana. Undang-Undang Informasi dan Transaksi Elektronik yang telah direvisi pada akhir tahun 2016, ternyata tidak dapat mengatasi masalah sosial yang terlanjur terjadi di internet. Faktanya, Undang-undang saja tidak akan cukup untuk mengatasi masalah sosial. Sebenarnya, yang lebih dibutuhkan masyarakat adalah pengetahuan tentang literasi digital.

    Zeolites are materials with a wide industrial application, which has motivated the development of a large number of scientific papers on this topic. This work presents a kinetic study of the formation process of sodalite produced from the reaction of the kaolin waste in the presence of sodium hydroxide solution (5M) performed at temperatures of 80, 100, 120 and 150 ° C. The process was conducted in batch, static, and autoclaves lined with Teflon, and monitoring the kinetics was performed by ex situ XRD analysis of the materials obtained in the time interval from 2 to 24 hours. The kinetic model that best describes this transformation is zero-order homogeneous reaction. Finally, we conclude that the technique of X-ray diffraction is a powerful tool to study the kinetics of phase transformation ex situ. (author)

    Full Text Available Many cases of fraud are exposed where someone, claiming to be someone else attempts to accesssomething. This situation challenges us to create a system that is both reliable and trustworthy to verify someone’sidentity. A biometric system represent an automatic recognition system based on the physiological characteristicsand/or behaviors of the human being. One of these biometric system is fingerprint recognition. Fingerprint verification system is a system to verify a human fingerprint according to the identity which has been claimed. Thusfingerprint image input is compared with the reference fingerprint image which has been kept in a database,according to the given identity. On this research, the Gabor Filter Bank-based Fingerprint Matching Method is used to extract the image features.On application, one of sample image will be matched with one of the database reference image. First, before matching, the sample image features need to be calculate using the aforementioned method. The resulting matchingprocess will find a reference image which has the shortest Euclidean distance with the sample image. This matchingprocess will only succeed if the sample image and the reference image are from the same person. Images used inthis research are fingerprint images with dimension 191 x 191 pixels. This research is looking for the successful rateand the burst time on the verification process. Result of the system testing show that Gabor Filter Bank Method canprovide high enough success level i.e. 95%. The items influence success level are subject to quality of fingerprint image and accuracy to find a reference point/core point, Similarity between query image and reference image is determined by projection distance both of images, and also threshold value is used to decide whether this image isvalid or not.

    Full Text Available Abstract: Biometric is a development of basic method of identification using human natural characteristics as its basic. One of the biometric system that is often used is fingerprint. Fingerprint matching system can be obtained by extraction of minutiae information. Information from minutiae extraction generated ridge ending and bifurcation. The technique coffered in this paper is based on the extraction of minutiae from fingerprint image using crossing number (CN method to get ridge ending and bifurcation point by scanning each of ridges point. False identification of minutiae structure may be introduced into the fingerprint image due to hole and spur structure. It is necessary to test the validity of each minutiae point to eliminate false minutiae. Experiments are firstly conducted to assess how well the crossing number method is able to extract the minutiae point. The minutiae validation algorithm is then evaluated to see how effective the algorithm is in detecting the false minutiae. From experiments result using crossing number method, it can be deduced that all ridge points corresponding to ridge ending and bifurcation point have been detected successfully. However, there are a few cases where the extracted minutiae do not correspond to true minutiae points due to hole and spur structure. Applying minutiae validation algorithm is able to cancel out the false ridge endings created by the spur structure and bifurcations created by the hole structures.

    Capim and Jari are the two most important kaolin mining districts of the Brazilian Amazon region. They encompass the major Brazilian reserves of high quality kaolin for the paper coating industry. The kaolin is mined and processed by three major companies responsible for about 500,000 ton of a residue mainly composed of kaolinite. The wastes come mainly from the centrifugation phase of the kaolin beneficiation process and their final destinations are huge sedimentation basins that occupy large areas. The main purpose of this work is to evaluate the physical, chemical and mineralogical characteristics of the kaolin wastes processed from the Capim and Jari region, in order to obtain meta kaolinite, a high reactive pozzolans for the cement industry. When incorporated to ordinary Portland cement such pozzolans increases the concrete and mortars performance. All the residues studied in this work were characterized by means of: X-ray diffraction analysis, differential thermal analysis, infrared spectroscopy, scanning electron microscopy, X-ray fluorescence spectrometry and laser diffraction. Both residues are mainly constitutes by at least 92% of low granulometry kaolinite with specific surface area above 8 m2 /g and mean diameter below 1 {mu}m. Free silica (quartz) contents are below 3%. The high concentration of kaolinite in these residues dispenses rigid control parameters for removal of impurities usually employed in pozzolans production. The Jari kaolin exhibits high disordered kaolinite in comparison with the high ordered kaolinite of the Capim region and gives rise to higher desidroxilation degree at lower temperatures. It points to energy saving and reducing costs during the production of a pozzolans. The results are satisfactory and reveal that both kaolin wastes are excellent raw material for the production of high reactive meta kaolin. (author)

    Full Text Available During 2012–2015, an entomological survey was conducted as part of a phlebotomine (Diptera: Psychodidae monitoring program in an area influenced by the Santo Antônio do Jari hydroelectric system (Amapá State, Brazil. The purpose was to study aspects of Amazon/Guianan American cutaneous leishmaniasis (ACL vectors subjected to stresses by anthropogenic environmental changes. For sampling, CDC light traps were positioned 0.5, 1, and 20 m above ground at five capture locations along the Jari River Basin. Fluctuations in phlebotomine numbers were analyzed to determine any correlation with rainfall, dam waterlogging, and/or ACL cases, from May 2012 to March 2015. We captured 2,800 individuals, and among 45 species identified, Bichromomyia flaviscutellata, Nyssomyia umbratilis, and Psychodopygus squamiventris s.l. were determined to be the main putative vectors, based on current knowledge of the Amazon/Guianan ACL scenario. Rainfall, but not complete flooding, was relatively correlated with phlebotomine fluctuation, mainly observed for Ps. squamiventris s.l., as were ACL cases with Ny. umbratilis. Behavioral changes were observed in the unexpected high frequency of Bi. flaviscutellata among CDC captures and the noncanopy dominance of Ny. umbratilis, possibly attributable to environmental stress in the sampled ecotopes. Continuous entomological surveillance is necessary to monitor the outcomes of these findings.

    2009-01-01

    Mullite is a relatively rare mineral in nature, formed under exceptional conditions of high temperature and pressure, which can be used to synthesize this mineral. Mullite presents good chemical and thermal stability among others properties that explain the importance of mullite in traditional and advanced ceramics. This research proposes the development of a process to synthesize mullite using the wastes from kaolin processing industries located in the Rio Jari (Monte Dourado-PA) and Rio Capim (Ipixuna-PA) districts. The synthesized materials will be studied for application as silicon-aluminum refractory bricks. The steps are mineralogical and chemical characterization, verifying the differences between the materials processing through firing of the wastes at increasing levels of temperature with 100 deg C increments, ranging from 600 to 1000 deg C and 1200 to 1500 deg C, during 3 hours at each level. Methods include the study of temperature and impurities effects through X-ray-powder and scanning electron microscopy. (author)

    The uptake and utilisation of phosphate from different jute growing soils of West Bengal viz., Humaipur (24-Parganas), Haripal (Hooghly), Panagarh (Burdwan) and the Jute Agricultural Research Institute, Barrackpore (24-Parganas) were studied in pot under fertilizer combination of NP, PK and NPK. The soils from 24-Parganas district behaved in a similar manner with respect to dry matter yield, fertilizer P uptake and per cent utilisation of added P. The P deficient between the two, Humaipur soil, showed comparatively higher P utilisation. Other two soils, Haripal and Panagarh, though of different origin behaved similarly, highest soil P has been contributed by the P rich soil (J.A.R.I.) to the crop, though it showed minimum P fixation.

    A necessary condition is derived for optimal J-ary coherent demodulation of M-ary (M greater than 2) signals. Optimality is defined as maximality of the symmetric cutoff rate of the resulting discrete memoryless channel. Using a counterexample, it is shown that the condition derived is generally not sufficient for optimality. This condition is employed as the basis for an iterative optimization method to find the optimal demodulator decision regions from an initial 'good guess'. In general, these regions are found to be bounded by hyperplanes in likelihood space; the corresponding regions in signal space are found to have hyperplane asymptotes for the important case of additive white Gaussian noise. Some examples are presented, showing that the regions in signal space bounded by these asymptotic hyperplanes define demodulator decision regions that are virtually optimal.

Dessa forma, o objetivo do trabalho foi avaliar o número de sementes de aveia preta resultantes de dois sistemas de manejo (colheita e ressemeadura natural, que poderão formar o banco de sementes do solo. Os ensaios foram realizados no município de Jari - RS, em uma área cultivada sob o sistema de "plantio direto". Foram coletadas 50 amostras em cada sistema de manejo, com um espaçamento de 10x20m, utilizando um amostrador de diâmetro de 0,05m e uma profundidade de 0,1m. O levantamento do número de sementes e da emergência das plântulas foi realizado no Laboratório Didático da Faculdade de Agronomia Eliseu Maciel (UFPel. Constatou-se que a colheita e a ressemeadura natural possibilitam a presença de sementes no solo por área, em quantidades superiores à indicada para a semeadura. Com a colheita, a área fica heterogênea em número de sementes no solo e em plântulas emergidas. A ressemeadura natural resulta em uma grande quantidade de sementes no solo e formação de plântulas.The black oat (Avena strigosa Schreb. seeds are able to remain alive in soil from a culture to another.

    Full Text Available O objetivo da investigação foi quantificar a variabilidade da qualidade físico-química e microbiológica da água sob influência da precipitação mensal no Baixo Rio Jari-AP. Este trecho da bacia hidrográfica é considerado como de alto risco às enchentes periódicas. A metodologia de estudo consistiu em coletas mensais de água superficial durante os meses de novembro de 2009 a novembro de 2010, em quatro sítios amostrais definidos em um trecho de 36 km, localizado em frente da cidade Laranjal do Jari-AP. No total, dezesseis parâmetros da qualidade da água foram analisados por amostra. Os resultados foram comparados com as referências do CONAMA 357/2005 (classe 2 e submetidos a uma análise de correlação de Spearman, a qual foi utilizada para quantificar o grau de associação entre parâmetros da qualidade da água e a precipitação mensal. Os parâmetros cor, turbidez, Al+3 , Mn+2 e E. coli apresentaram significativa correlação com a precipitação média mensal. Além disso, altas concentrações de DBO e Coliformes Totais (CT indicaram maior vulnerabilidade ou risco do corpo d´água estar relacionado com doenças potenciais de veiculação hídrica em períodos mais chuvosos. Também, os parâmetros cor, Fe, CT e E. coli apresentaram-se em não conformidade com a legislação CONAMA 357/2005. Concluiu-se que a alteração da qualidade da água tende a se agravar, em termos de vulnerabilidade ou risco à saúde pública, durante eventos mais chuvosos ou de precipitação extrema.

    The system of active faults in the region between the southern flank of the Montes del Aguacate and the northwest flank of the Talamanca mountain range was re-evaluated and defined in relation to the seismic activity that occurred between the end of March 1990 and the beginning of 1991. Aerial photographs of different scales of the Instituto Geografico Nacional de Costa Rica, aerial photographs of scale 1: 40000 of the TERRA project, of the Centro Nacional Geoambiental and infrared photos of scale 1: 40000 of the Mission CARTA 2003, of the Programa Nacional de Investigaciones Aerotransportadas y Sensores Remotos (PRIAS) were reviewed. Morphotectonic, structural and geological information related to the various faults was obtained with field work. A set of faults within the study area were determined with the neotectonic investigation. Several of these faults continue outside the zone both to the northwest within the Montes del Aguacate, and to the southeast to the NW foothills of the Cordillera de Talamanca. The superficial focus seismicity (<20 km), which occurred in the Puriscal area during 1990, was revised from previous studies, whose base information comes from the Red Sismologica Nacional (RSN, UCR-ICE). The relationship between the superficial seismic sequence and the defined faults was determined, allowing to conclude that the main seismic sources that originated the seismicity were the Purires and Picagres faults. A minor seismicity was related to the faults Jaris, Bajos de Jorco, Zapote and Junquillo [es

    Various evaluations of the neutron cross sections of 242 Pu lead to widely different predictions of bulk neutronics properties such as critical mass. These evaluations also show rather different behavior of the energy dependence of the total cross section. The total cross section of 242 Pu from 0.7 to 170 MeV was measured to a statistical accuracy of = 0.5% below 6 MeV, using 8 g of high purity material and the WNR pulsed neutron facility. Recent evaluations by Madland and Young and by Lagrange and Jary are found to be reasonably consistent with the data obtained. Best agreement, however, is found by using a relationship between the total cross sections for 238 U, 239 Pu, and 235 U. The remarkable accuracy of this description for 242 Pu suggests that it could be extended to other deformed actinides for which inadequate amounts of material exist for direct measurements of sigma/sub T/ in the MeV region, as an evaluation constraint

    Polymer electrolyte fuel cells (fuel cells) can be potentially employed as sources of clean energy because they discharge only water as by-products. Fuel cells generate electricity with supply of oxygen and hydrogen gases. However, the water produced by the fuel cells blocks the gas supply, thereby degrading their performances. Therefore, it is important to understand the behavior of the water produced by the fuel cells in order to facilitate their development. Neutron radiography is a useful tool for visualizing the distribution of water in fuel cells. We have designed fuel cell operation system for TNRF (Thermal Neutron Radiography Facility) at JRR-3. The fuel cell operation system consists of various components such as gas flow and humidification systems, hydrogen-diluting system, purge system, and safety system for hydrogen gas. We tested this system using a Japan Automobile Research Institute (JARI) standard cell. The system performed stably and efficiently. In addition, neutron radiography tests were carried out to visualize the water distribution. The water produced by the fuel cell was observed during the fuel cell operation. (author)

L’histoire récente de cette région est indissociablement liée à l’installation en 1967, par l’entrepreneur Américain D.K. Ludwig, d’une entreprise agro-industrielle, la Jari Cellulose S.A., pour la production de pâte à papier à grande échelle, reposant sur des plantations extensives, alors que la région était déjà peuplée de petites communautés vivant de cueillette et d’agriculture de subsistance. Avec l’arrivée de l’entreprise, la région a connu un important changement de cap, caractérisé par une nouvelle dynamique économique, mais aussi par des impacts sociaux et écologiques considérables, dont les effets contradictoires entre développement et conservation en contexte de l’Amazonie forestière n’ont pas encore été résolus dans la région aujourd’hui. Le voyage raconté ici est la dernière et plus lointaine excursion entamée pendant le travail de terrain. Il nous amène aux communautés de l’Estrada Nova, territoire situé au sud-ouest du domaine de l’entreprise Jarí Cellulose. Ici, la plupart des familles des communautés vivent dans un isolement prononcé, en indépendance absolue de l’entreprise où en coopération silencieuse avec celle-ci. L’article suivant inclut plusieurs témoignages de quelques-uns des personnages clefs rencontrés au cours de l’expédition au et à travers de l’Estrada Nova.This article is based on a prolonged fieldwork carried out in the Brazilian Amazon region between January and August 2009 for a PhD in geography about the rise and development of the Jarí river region, a trans-border territory between the Amapá and the Pará state

    Full Text Available A dimensão do Brasil e a diversidade da geologia se reflete em vários meios nos quais montagens de caulinita foram formadas. Os meios geológicos dos caulins brasileiros podem ser divididos nos seguintes grupos - caulins sedimentares, caulins oriundos de pegmatitas, de rochas graníticas, de rochas vulcânicas, e caulins derivados de anortosito. As argilas sedimentares são encontradas principalmente na bacia amazônica e aquelas adjacentes ao rio Jari estão sendo exploradas comercialmente para exportação como argilas para recobrimento de papel. Os caulins amazônicos são caracterizados por alto teor de ferro e titânia (estruturais com baixos níveis de álcalis e exibindo cristais de caulinita euédricos. As pegmatitas do sudeste, quando não recobertas com óxido de ferro, tem extremamente baixos teores de ferro e titânia e uma mistura de caulinita 7Å / haloisita 10Å ocorre em todos depósitos. As pegmatitas do nordeste produzem caulins constituídos somente por caulinitas euédricas com ausência de haloisita. Os caulins de granito tem geralmente maiores teores de ferro quando comparados com pegmatitas e são raros os depósitos constituídos somente por caulinita, sendo comum uma mistura de caulinita 7Å / haloisita. Os caulins obtidos da pegmatita e do granito são utilizados como cobertura de papel e em cerâmica em geral. Argilas de origem vulcânica são utilizadas em cerâmicas na região. Os caulins obtidos de anortosito são semelhantes em níveis de ferro e titânia àqueles obtidos de caulins graníticos. Montagens de caulinita e pequenas quantidades de haloisita 7Å são encontrados.

    Full Text Available The author examines the concept of «McUniversity», introduced in 1995 by British sociologists M.Parker and J.Jary. However, attention is drawn to the concept of McDonaldization, masovization that lead to the emergence of phenomena of economization in education. It is noted that the principle of McDonaldization is used by the most businesses organizations, and the McDonald’s is the epitome of efficiency, predictability and automation; gradually moving to the University, it manifests itself in rationalization, excessive consumption, the use of advertising, which creates the illusion of consumer cooperation, which focused on human behavior, freedom and impartiality. The article states that the educational sector reformers often confuse economization of education and its commercialization. The processes of economization of education are one of the most important factors of economic development and cause change. After all, education is increasingly starting to be not as education for education and obtain «pure knowledge», namely as a powerful fact of development that allows countries to enter new innovative technological frontier. In general, education is seen as a major factor of social and economic progress and stability of the social system. So the concept of «McUniversity», introduced in 1995, is becoming increasingly important today, setting the stage for the development of the economization of education in our society, because the modern era characterized rankings of universities and faculties at the international and national levels, strengthening the competitive spirit among faculties and tutors, establishing schools and faculties that operate as businesses due to the fact that they perform managerial principles.

Melalui pendekatan etnomusikologi, tulisan ini menelaah peranan musik internal dan eksternal dalam kesenian Randai. Kesenian ini menggunakan medium seni ganda atau kolektif karena didukung oleh beberapa cabang seni antara lain tari, musik, teater, sastra, dan rupa. Hasil penelitian menunjukkan bahwa musik iringan dalam Randai terbagi menjadi dua, yaitu musik internal dan musik eksternal. Musik internal adalah musik atau bunyi-bunyian yang berasal dari anggota tubuh manusia (penari, misalnya tepukan tangan, petik jari, tepuk dada, siulan, hentakan kaki ke tanah dan sebagainya, sedangkan musik eksternal adalah bunyi-bunyian atau suara yang berasal dari alat musik atau instrumen seperti talempong, gandang, saluang, dan rabab.   The Role of Internal and External Music in the Arts of Randai. The musical life in Minangkabau society is inseparable from its roles and functions which attach to the arts of Randai. Through the ethnomusicology approach, this paper examines the role of internal and external music in the art of Randai. Considering its sustainability and amendment, the musicality is the identity of Minangkabau society so that the sustainability of the music can be run in accordance with the dynamics of society today. Among the types of arts in Minangkabau, Randai is an art form that uses multiple or collective art medium for it is supported by several branches of the arts, including dance, music, theater arts, literary arts, and fine arts. The results of this study is more focused on the art of music. Musical accompaniment in Randai is divided into two, namely internal and external music. The internal music is the music or the sounds that come from the human body (a dancer, for example, clapping, finger picking, patting the chest, whistling, stomping on the ground, and so on, while the external music is the sounds

Untreated, it is a potentially devastating disease; however, diagnosis can be difficult due to the non-specific nature of symptoms during the early stages, and the fact that patients often present to a range of different medical specialties. The past decade has seen remarkable improvements in our understanding of the pathology associated with the condition and the development of PAH-specific therapies with the ability to alter the natural history of the disease. This article reviews the evidence for screening and diagnosis of susceptible patient groups and discusses treatment selection and recommendations based on data available from randomized controlled trials. In addition, due to the complexity of the diagnostic evaluation required and the treatment options available, this review mandates for a multidisciplinary approach to the management of PAH. We discuss the roles and organizational structure of a specialized PAH center in Perth, Western Australia to highlight these issues.

Sebelum berkembangnya kerapu hibrid, Balai Besar Penelitian dan Pengembangan Budidaya Laut Gondol, sudah berhasil mengembangkan pembenihan ikan kerapu bebek meskipun sintasan yang diperoleh masih bervariasi. Pemantauan benih hasil budidaya sebagian besar terfokus pada pertumbuhan dan jika sudah mencapai ukuran konsumsi bisa dijual atau diekspor ke Hongkong. Sebagai institusi penelitian nampaknya masih perlu mengupas lebih detail komoditas yang dikembangkan. Beberapa catatan yang dapat diperhatikan, untuk lebih mengenal komoditas kerapu bebek, sebelum dijadikan sebagai ikon jenis ikan yang pernah memiliki masa kejayaan, karena saat ini popularitasnya relatif menurun karena ada larangan ekspor dan masuk dalam satwa CITES. Catatan tersebut antara lain; kerapu bebek selama fase yuwana (2-3 bulan dapat dijadikan sebagai kandidat ikan hias dengan performasi bintik bintik hitam pada permukaan tubuh yang merupakan keunikan tersendiri, karena jumlah dan polanya berbeda antara satu individu dengan yang lainnya serta akan bertambah jumlahnya seiring dengan bertambahnya umur dan bobot badan. Spot/bintik hitam kemungkinan identik dengan sidik jari manusia, yang bisa digunakan untuk membedakan antara satu individu dengan individu lainnya dalam satu populasi. Gonad kerapu bebek turunan pertama (F1 dengan umur dan kisaran bobot badan yang kurang lebih sama (600-900 g, menunjukkan 95% berada pada fase betina. Sementara pematangan dan pembentukan gonad jantan pada kerapu bebek hasil budidaya dapat dipacu dengan rangsangan hormonal dan pemberian pakan segar dengan kualitas yang baik. Dari hasil pengamatan diperoleh informasi bahwa kerapu bebek hasil budidaya dapat memijah dengan baik dan menghasilkan turunan generasi kedua (F2, akan tetapi kualitas telur dan larva yang dihasilkan masih lebih rendah bila

Here, we compared outcomes of primary RRD eyes operated with conventional scleral buckling (SB with cryoretinopexy to those operated with standard pars plana vitrectomy (PPV. Methods: This is an institutional, retrospective, register-based, observational, comparative study. Based on the surgical procedure, 319 eyes of 319 patients were divided into two groups: SB plus cryotherapy (n=50 and PPV (n=269. Changes in intraocular pressure (IOP and best-corrected visual acuity (BCVA were recorded at 30 days and reoperation rates within 180 days postoperatively. Results: Eyes operated with PPV had less reoperations within the first 180 days as compared with SB eyes (P=0.001, log-rank test; however, changes in IOP were more prominent (mean ± standard deviation: +8.1±8.8 vs. +4.4±7.0 mmHg, respectively; P=0.006. Changes in BCVA did not differ between the surgical procedures. Conclusion: PPV was associated with higher primary anatomic success rates and lower risk of reoperation but significant IOP elevation when compared to SB. These factors should be case-specifically considered when choosing treatment modality for primary RRD. Keywords: rhegmatogenous retinal detachment, vitrectomy, scleral buckling

    Full Text Available Les phénomènes climatiques de type “ El Niño ”, et son inverse “ La Niña ”, perturbent fortement le climat des régions tropicales du versant Pacifique (Pérou, Équateur, Colombie. Les perturbations du régime des précipitations altèrent à leur tour le régime hydrologique des fleuves de ces régions. Aussi l’analyse des longues séries hydrologiques est un outil pratique pour détecter l’ampleur et l’étendue de l’influence du “ Niño/Niña ” sur une région donnée. Cette analyse des séries chronologiques de débit a été menée sur 17 stations hydrologiques du DNAEE dans le bassin amazonien du Brésil. Les résultats obtenus montrent de bonnes corrélations entre l’indice d’oscillation austral (ENSO et l’indice des débits dans la partie nord-est du bassin (rios Branco et Jari. Ailleurs, des tendances régionales sont observées, mais ne sont pas toujours significatives. Dans le cas de l’Amazone à Óbidos, le “ Niño ” de 1983 a entraîné une chute de 16% du débit moyen annuel, alors que la “ Niña ” de 1989 est responsable d’un excédent de 14% du débit annuel.

This is a qualitative study, based on a single case study and on organizational level analysis. The survey involved eight respondents among directors, managers, HR professionals, supervisors, and coordinators from the Orsa Group - specifically, within Jari Celulose, Orsa Florestal, and Fundação Orsa. Primary data were collected through in-depth interviews and observations in the operational areas; secondary data were collected through analysis of documents and websites. For data analysis, the techniques of content analysis of interviews and reflexive methodology were used. The theoretical basis includes organizational behavior, organizational commitment, strategic management of people, and organizational culture. Results show the existence of favorable and unfavorable factors for the management of people in this organization, leading to the creation of a culture in which organizational identity and values are shared and, above all, in which organizational commitment becomes possible to be achieved.El objetivo principal de este trabajo es investigar las peculiaridades de la gestión estratégica de personas en una empresa con una estructura organizacional remota, confinada y aislada de los grandes centros urbanos.

    The development of the WorldSID 50th percentile male dummy was initiated in 1997 by the International Organisation for Standardisation (ISO/SC12/TC22/WG5) with the objective of developing a more biofidelic side impact dummy and supporting the adoption of a harmonised dummy into regulations. More than 45 organizations from all around the world have contributed to this effort including governmental agencies, research institutes, car manufacturers and dummy manufacturers. The first production version of the WorldSID 50th male dummy was released in March 2004 and demonstrated an improved biofidelity over existing side impact dummies. Full scale vehicle tests covering a wide range of side impact test procedures were performed worldwide with the WorldSID dummy. However, the vehicle safety performance could not be assessed due to lack of injury risk curves for this dummy. The development of these curves was initiated in 2004 within the framework of ISO/SC12/TC22/WG6 (Injury criteria). In 2008, the ACEA- Dummy Task Force (TFD) decided to contribute to this work and offered resources for a project manager to coordinate of the effort of a group of volunteer biomechanical experts from international institutions (ISO, EEVC, VRTC/NHTSA, JARI, Transport Canada), car manufacturers (ACEA, Ford, General Motors, Honda, Toyota, Chrysler) and universities (Wayne State University, Ohio State University, John Hopkins University, Medical College of Wisconsin) to develop harmonized injury risk curves. An in-depth literature review was conducted. All the available PMHS datasets were identified, the test configurations and the quality of the results were checked. Criteria were developed for inclusion or exclusion of PMHS tests in the development of the injury risk curves. Data were processed to account for differences in mass and age of the subjects. Finally, injury risk curves were developed using the following statistical techniques, the certainty method, the Mertz/Weber method, the

    Radiogenic isotopes in river sediments and river waters have been widely used in provenance studies, as these samples naturally integrate the geology/chemistry of the entire catchment. While the Hf and Nd isotope systems are coupled during igneous processes, they are decoupled during supergene processes at the Earth's surface, which is reflected by the isotope composition of riverine sediments. We present the first data for both Hf and Nd isotope compositions of the dissolved (0.2 μm-filtrates rich in nanoparticles and colloids, NPCs) and the truly dissolved (1 kDa-ultrafiltrates) load of rivers. Hafnium and Nd isotope compositions and concentrations of the Rare Earths and Yttrium (REY) and Hf were determined for suspended particles (>0.2 μm) as well as for the dissolved and the truly dissolved load of the Rio Solimões, the Amazon's largest tributary draining the Andes, and of the Rio Negro, an organic NPC- and particle-rich river draining the rainforest of northern Amazonia. We also analyzed the Nd isotope compositions of suspended sediments and 0.2 μm-filtered water samples from the Amazon River and its tributaries Rio Tapajos, Rio Xingu and Rio Jari. Our novel results clearly show that the decoupling of the Hf and Nd isotope systems is related to incongruent weathering processes on the continent, as this decoupling can already be observed in the different Hf and Nd pools, i.e. in the particulate, the NPC-dominated dissolved and the truly dissolved load of rivers. In the Rio Negro and Rio Solimões, a strong particle size-dependent difference in Hf isotope composition is observed. Values of εHf become more radiogenic as filter poresize decreases, which can be related to the density- and size-dependent distribution of Hf-rich minerals, e.g. zircons, and their absence from the truly dissolved pool. In contrast, the Nd isotope composition of Amazonian river waters reflects that of their catchment geology. Tributaries draining the Precambrian Brazilian and

The stand was measured in 1984, logged in 1985 and remeasured in 1986, 1988, 1990, 1994, 1996 and 2004. All the trees with DBH ≥ 20 cm were measured. While keeping the same simplicity of transition matrix based models, the proposed model allows for determining the state of the system for any given point in time, not being confined just for multiplying time intervals as was the former. This method was verified for different evaluation periods and the results showed that not even the longer periods of projections (break-even point will be enough to restore the initial conditions of the stand.

    Full Text Available Abstrak; Ada kegelisahan sebagian pengguna perpustakaan ketika sedang mengkaji Islam di Indonesia berbasis naskah kuno. Salah satu kegelisahan itu adalah ketidaktersediaan sumber informasi tentang naskah kuno Nusantara di perpustakaan PTKIN. Informasi naskah kuno yang paling sederhana ini melalui katalog naskah kuno. Di Indonesia, katalog naskah kuno ini sudah ada sejak tahun 1950 oleh Poerbatjaraka, Voorhoeve, dan Hoykaas dengan titel Indonesische Handschriften hingga saat ini. Katalog naskah Nusantara itu memuat informasi asal usul naskah, isi naskah, dst. Lebih jauh lagi, tentu saja seharusnya perpustakaan PTKIN menyediakan naskah-naskah kuno tersebut, sekalipun dalam bentuk digital. Salah satu bentuk penyelamatan naskah kuno itu melalui program digitalisasi. Dalam konteks itulah filologi Nusantara penting untuk menjadi alat bantu dalam pengembangan perpustakaan PTKIN. Sebenarnya, filologi bukanlah ilmu baru di lingkungan PTKIN. Sebagai mata kuliah, filologi atau studi naskah kuno diajarkan pada Jurusan/Program Studi Sejarah Kebudayaan/Peradaban Islam Fakultas Adab dan Humaniora. Hanya saja, kajian Islam berbasis filologi masih dapat dihitung dengan jari. Karena itu, sangat wajar juga jika pihak perpustakaan hingga saat ini masih belum ada koleksi khusus tentang hal itu. Berangkat dari kegelisahan itulah nampaknya penting diungkapkan saat ini sebagai kajian awal tentang filologi Nusantara dan perpustakaan. Pengalaman kecil di Pusat Perpustakaan IAIN Syekh Nurjati Cirebon melalui layanan khusus Cirebonese Corner dapat menjadi pintu awal kajian ini. Abstract; There are discomfort and worry among library users when they want to study Islam in Indonesia based on ancient manuscripts. One of them is caused by the unavailability of primary references about ancient manuscripts in the library of PTKIN. In the meantime, they find them such references by searching through a catalog of ancient manuscripts which has been around since the 1950s, written by

    and 2007 [Rühr(2009)] and present soil carbon stocks [Heim et al.(2009)]. Our Results show, that for short-term soil carbon dynamics, e.g. estimates of heterotrophic soil respiration on an annual basis, the inclusion of the dependency on litter quality is not necessary, as the differences are minor only. However, when considering long-term soil carbon dynamics, e.g. simulated estimates of present soil carbon content, the dependency on litter quality shows effect, as there are correlations with specific site factors such as site location and forest type. The inclusion of the dependence on litter quality therefore may be of importance for the projection of future soil carbon dynamics, as forest types may well be altered due to climatic change.

    Full Text Available Media Education Conference (MEC 2015 “In the Light of the Midnight Sun” was organized in Sallatunturi, Finland in 15-17 of June 2015. Selected papers submitted by the conference participants are published in this special issue of seminar.net.MEC (former NBE is an informal and friendly conference which participants attend to exchange ideas and information dealing with media education, educational use of ICTs and learning environments. MEC is organized by the Centre for Media Pedagogy at the University of Lapland.Themes and topics of the sixth MEC conference were as follows: Playful and Game-based Learning; Media and Code Literacies; Empowerment through Media; Media and ICT in Teaching and Learning; Digital Story Telling; 3D, Virtual and Simulation-based Learning; and Internet and Social Media in Everyday Life.In the first article, Tuulikki Keskitalo and Heli Ruokamo of the University of Lapland present “A model for simulation-based learning in healthcare”. Simulations and virtual reality do have a major focus in current healthcare education. The authors designed the study in order to fill a gap about our knowledge the pedagogical models that underpin the present activities. They studied several cases involving facilitators and students, in order to find out when and how simulations should and could be used for the benefit of the students and their learning. They describe how a refined pedagogical was developed, a model that will provide a more holistic and meaningful approach to teaching and learning in health care.The second article is written by a group pf researchers from the university of Eastern Finland, Teemu Valtonen, Erkko T. Sointu and Jari Kukkonen of the department situated in Joensuu, while Kati Mäkitalo-Siegl is based in Savonlinna.

    these investigations to the same level of completeness as the others. Team 1a: Participants: Amanullah, De Beer, Huertas Rodriguez, Huijbregts, Kranz, Olsen, Oppelstrup; Team leaders: Jari Ronnback and Frederic Courbin This team used the multi-mode EMMI instrument at the 3.5-m NTT to observe so called `Interacting Galaxies'. These are galaxies which are so close to each other that their shapes are distorted by the action of their gravitational fields. Some of them are actually in a state of collision. Direct CCD images were obtained of a total of 8 galaxies; 7 of these were observed in one colour (red) and 1 in two (red and yellow-green). The programme comprises a selection of different types of galaxies (Elliptical + Elliptical; Elliptical + Spiral; etc.) and different types of interactions (direct collision; fly-by; etc.). The observing conditions were quite good, with seeing from 0.5--1.2 arcseconds and some of the images obtained are probably the best ever made of these particular objects. The team classified the types of involved, heavily distorted galaxies and attempted to decide what type of interaction is occurring. A very nice and instructive pictorial Atlas will be produced from this material. Team 1b: Participants: Barth, Bonander, Ching, Ciarletta, EresmA, Wiedemann, Wieland; Team leaders: Paul Goudfrooij and Frederic Courbin This team obtained short-exposure direct images and long-exposure long-slit spectra with NTT + EMMI of two peculiar galaxies, the edge-on distorted spiral NGC 1448 and the elliptical NGC 1947 which has a crossing dust lane. One IRAS superluminous galaxy was also observed. The latter part of the night was characterized by exceptionally good seeing (down to 0.3 arcsecond!), permitting to see many details in these galaxies, which have never been perceived before. For instance, several hitherto unknown dust lanes were found in the outer regions of NGC 1947 ! The slits were placed through the central part of the galaxies and along the major
