Numerical modeling of open pit (OP) to underground (UG) transition in coal mining
Authors: Nguyen Phu Minh Vuong , Niedbalski Zbigniew 
Published: November 2016

Abstract
The primary objective of the present paper is an attempt at evaluating the influence of sub-level caving operations on the slope stability of a still-functioning open pit coal mine in Vietnam. Initially, various methods of predicting the impact of underground mining on surface stability are discussed. Those theoretical considerations were later utilized in the process of constructing a Flac-2D-software-based numerical model for calculating the influence of underground operation on the deformation and possible loss of stability of an open pit slope. The numerical analysis proved that the values of open pit slope displacements were affected mainly by underground exploitation depth, direction of operation (i.e., from one slope to the other) and the distance from the slope plane. Real geomechanical strata parameters from the Vietnamese coal basin of Cam Pha were used in the modeling process. The paper is, therefore, a critical review of the hitherto proposed methods of predicting the impact of underground operation (UG) on open pit mining (OP), illustrated with selected examples of case studies on OP-UG interaction, followed by an original experiment based on numerical modeling method. This is first such study for the genuine conditions of the coal mining in Vietnam. The obtained results, however, should not be generalized due to a highly specific character of the analyzed phenomenon of mining-induced surface deformation. The practical implications of the study may occur extremely useful in the case of an UG-OP transition. Such a transition is often necessary for both technical and economical reasons, as in some coal basins open pit operations at greater depths occur unfeasible, which calls for a proper selection of parameters for a planned underground operation.

Published: November 2016

Abstract

Introduction
The main research objective is the analysis of the grouping of the students of the University of Ljubljana, with respect to the intensity of different types of exercise participation motives, their gender, discipline and year of study, level of physical activity, status of physical education class, organization of physical activities during study, and place of residence.

Methods
Data were collected using personal data sheets during enrolling students at the University of Ljubljana. Students completed The Exercise Motivations Inventory (EMI-2), with additional data about sociodemographic parameters.

Results
The results reveal that the students could be grouped in three distinctive clusters, which can be very clearly explained in terms of the prevalence of exercise participation motives in general. The students grouped in the first cluster have the lowest average values (means) in all exercise participation motives. The students grouped in the second cluster have the profile with moderate means in all exercise participation motives, while the students grouped in the third cluster have the profile with the highest means in all exercise participation motives.

Conclusions
The results indicate overall higher motivation for physical activity in men. All the sub-samples are different in their relevant features used in clustering (e.g., male students are dominant in life sciences, etc.), which provide a guide both for the explanation of the results obtained and for practical implications.
Sex Differences and Sex Identification in the Small-Scaled Scorpionfish, Scorpaena Porcus (Scorpaenidae, Scorpaeniformes)
Authors: Peskov V. N. , Manilo L. G. 
Published: November 2016

Abstract
Sex differences and the ability to determine the sex of Scorpaena porcus (Linnaeus, 1758) on morphological characters were studied in the population inhabiting coastal waters of the Black Sea near the southern coast of Crimea. These differences were revealed in size (females are larger than males) and in proportions of the body. It is found that variation of the absolute and relative values in plastic characters is higher in females compared with males. It is shown that in 92 % of individuals belonging to S. porcus we can determine the sex using morphological characters with a probability of 99.9-100 %.

Abstract
Iranian long legged wood frog, Rana pseudodalmatina Eiselt & Schmidtler, 1971 is a brown frog species endemic to the Hyrcanian forest. The objective of the present study is to collect detailed information on the feeding habits of 44 specimens of this species (24 ♂, 20 ♀) by analyzing the stomach contents of individuals from 10 populations inhabiting range. The food habit of R. pseudodalmatina generally varies by the availability of surrounding prey items, and it is a foraging predator, the food of which consists largely of Coleoptera (mainly Carabidae, Dytiscidae and Haliplidae), Diptera (Muscidae) and Hymenoptera (Formicidae), and no difference was found between females and males in the stomach content.
Get thee behind me, City God!
Authors: Klotz David 
Published: November 2016

Summary:
The most recent analysis of the Saite Formula by K. Jansen-Winkeln (2000), based on an exhaustive corpus of over 200 examples, concluded that it was essentially a dedication formula expressed in the passive voice, commemorating the proper sacralization of the statue. Two previously unrecognized examples, both from Nubia during the late Eighteenth Dynasty, show that the supposed passive verbal form must be understood as the imperative of rḏı͗, “to place”, written in its archaizing or abbreviated non-suppletive form. This calls for a new analysis of the religious meaning of the formula, restoring agency to both the dedicant and his protective City God.
Die hieratische Stele MAA 1939.552 aus Amara West – ein neuer Feldzug gegen die Philister
Authors: Popko Lutz 
Published: November 2016

Summary:
Edition of stela MAA 1939.552, which was discovered in Amara West in 1938, but which was never properly published. The text is of a military nature and records a yet unknown land battle against the Philistines in the year 3 of a king whose name is lost. Whereas the stela was previously assigned to Ramses IV, a dating into the reign of Ramses III is proposed, thereby predating the beginning of the conflict with this group of the Sea Peoples by five years. Moreover, the text is partially incised in hieratic, which is unusual for royal war reports, and thus it provides further, exceptional evidence for lapidary hieratic.
The Memory Trace Supporting Lose-Shift Responding Decays Rapidly after Reward Omission and Is Distinct from Other Learning Mechanisms in Rats
Authors: Gruber Aaron J. , Thapa Rajat 
Published: November 2016

AbstractThe propensity of animals to shift choices immediately after unexpectedly poor reinforcement outcomes is a pervasive strategy across species and tasks. We report here that the memory supporting such lose-shift responding in rats rapidly decays during the intertrial interval and persists throughout training and testing on a binary choice task, despite being a suboptimal strategy. Lose-shift responding is not positively correlated with the prevalence and temporal dependence of win-stay responding, and it is inconsistent with predictions of reinforcement learning on the task. These data provide further evidence that win-stay and lose-shift are mediated by dissociated neural mechanisms and indicate that lose-shift responding presents a potential confound for the study of choice in the many operant choice tasks with short intertrial intervals. We propose that this immediate lose-shift responding is an intrinsic feature of the brain’s choice mechanisms that is engaged as a choice reflex and works in parallel with reinforcement learning and other control mechanisms to guide action selection.

Os cuidados no fim da vida em perspectiva bioética: um olhar a partir da fé cristã
Authors: Menegatti Larissa Fernandes , Sanches Mário Antônio 
Published: November 2016

Este artigo propõe refletir o tema sobre cuidados no fim da vida numa perspectiva bioética a partir da fé cristã. Esta contribuição teórica é corroborada pela experiência vivencial de João Paulo II, por meio de seu próprio testemunho nos últimos dias antes de sua morte. De fato, a morte provoca questionamentos profundos com relação à nossa existência marcada pela condição inegável de finitude. Essa realidade fatal é muitas vezes experimentada antes por um ambiente de dor e sofrimento de todas as ordens que nos aflige em nossas enfermidades, pois anuncia com sua chegada a proximidade de nossa partida deste mundo. E por mais que formemos profissionais de saúde focados em conteúdos com ênfase em conhecimentos biotecnológicos, se faz necessária a inserção nos conhecimentos integrados que englobem os referenciais bioéticos a fim de distinguir os processos terapêuticos realizados. Nesse paradigma, a bioética apresenta-se como critério ético nas escolhas relacionadas entre biotecnologia e saúde.
Sinais de uma caminhada ecumênica no catolicismo
Authors: Lourenço Vitor Hugo 
Published: November 2016

O ecumenismo é a vocação primeira de todas as igrejas cristãs. Partindo dessa premissa, o presente artigo busca analisar, a partir do catolicismo, os sinais históricos de sua caminhada ecumênica mais recente. Para este propósito, tem-se como ponto de partida o Concílio Vaticano II, de modo particular o seu DecretoUnitatis Redintegratio (UR), visando compreender o que significa o ecumenismo, seus desdobramentos, implicações, avanços e retrocessos. Proporcionando um tempo de esperança e abertura na vida da Igreja Católica, o pontificado de Francisco tem se mostrado sensível ao diálogo ecumênico, mostrando e recuperando sinais de que o diálogo e o movimento ecumênico encontram novamente no catolicismo um solo fecundo para crescer e lançar novas sementes.

Background and aims
Gray’s Reinforcement Sensitivity Theory has been widely applied to different clinical populations, but few studies have reported empirical evidence based on this theory for treatment outcomes in patients with gambling disorder (GD) and compulsive buying (CB). The aims of this study were to explore the association between clinical variables and personality traits with reward and punishment sensitivity (RPS) levels in women (n = 88) who met diagnostic criteria for GD (n = 61) and CB (n = 27), and to determine the predictive capacity of RPS for primary short-term outcomes in a cognitive-behavioral therapy (CBT) intervention.

Methods
The CBT intervention consisted of 12 weekly sessions. Data on patients’ personality traits, RPS levels, psychopathology, sociodemographic factors, GD, and CB behavior were used in our analysis.

Results
High RPS levels were associated with higher psychopathology in both CB and GD, and were a risk factor for dropout in the CB group. In the GD group, higher reward sensitivity scores increased the risk of dropout.

Discussion and conclusions
Our findings suggest that both sensitivity to reward and sensitivity to punishment independently condition patients’ response to treatment for behavioral addictions. The authors uphold that CBT interventions for such addictions could potentially be enhanced by taking RPS into consideration.
Peran Mutu Dalam Menunjang Ekspor Udang Nasional
Authors: Putro Sumpeno 
Published: November 2016

Udang merupakan komoditi andalan ekspor dari sektor perikanan Indonesia. Akan tetapi, volume ekspor udang Indonesia dalam beberapa tahun terakhir ini cenderung menurun. Hal ini terutama disebabkan karena semakin ketatnya persyaratan impor yang diberlakukan oleh negara-negara maju, khususnya standar mutu dan sanitasi. Ekspor udang ke Uni Eropa merosot dan dikenakan RAS (Rapid Alert System) karena dicurigai mengandung residu antibiotik dan bakteri patogen. Ekspor udang ke Amerika Serikat, juga masih dikenakan automatic detention. Sementara itu, pada tahun 2006 dan 2007 ekspor udang ke Jepang dan Cina juga ditolak karena dicurigai mengandung residu antibiotik. Oleh karena itu, pengembangan sistem pembinaan mutu dan sertifikasi secara terpadu dengan konsep from farm to table sangat diperlukan untuk meningkatkan daya saing dan akses pasar dalam menghadapi era globalisasi. Dalam kaitan ini, pengembangan industri udang budidaya ke depan sebaiknya tidak hanya berorientasi kepada upaya peningkatan produksi, tetapi juga memperhatikan aspek mutu dan keamanan pangan (food safety) agar produk yang dihasilkan layak dan aman untuk dikonsumsi serta memenuhi standar mutu yang berlaku di pasar internasional.

Published: November 2016

Kerang hijau merupakan salah satu komoditas dari kelompok kekerangan (shellfish) yang sudah dikenal masyarakat, selain kerang darah (Anadara granosa), kijing Taiwan (Anodonta sp), dan kerang bulu (Anadara inflata). Kerang hijau telah berhasil dibudidayakan dan dapat dipanen setelah 6–7 bulan. Potensi kerang hijau di Indonesia cukup tinggi dan tersebar di beberapa perairan di Indonesia. Kerang hijau mengandung protein sekitar 16,7–21,9%, kaya akan asam amino esensial (arginin, leusin, lisin) dan mengandung mineral kalsium, fosfat, yodium, tembaga. Kerang hijau mengandung daging sekitar 30% dari bobot keseluruhan dan mempunyai nilai gizi yang tinggi, dengan demikian kerang hijau berpotensi sebagai sumber protein hewani yang relatif murah dibanding ikan. Penanganan terhadap kerang hijau agar aman dikonsumsi dapat dilakukan dengan cara pengurangan kandungan logam berat dengan perendaman dalam larutan kitosan 1,5% selama 3 jam dan teknik depurasi untuk menurunkan kandungan bakteri kerang hijau. Diversifikasi produk olahan merupakan salah satu cara untuk meningkatkan konsumsi kerang hijau di masyarakat dalam rangka meningkatkan asupan protein dan meningkatkan pendayagunaan hasil perikanan untuk diolah menjadi produk baru sebagai makanan bernilai gizi tinggi, enak, murah, dan mudah didapat. Produk inovatif olahan kerang hijau diantaranya kamaboko, kerupuk, kerang rebus dengan pewarna alami, hidrolisat protein, dan pasta condiment. Produk inovatif kerang hijau tersebut mempunyai peluang dikembangkan menjadi komoditi ekspor.

Karotenoid merupakan pigmen alami yang disintesis oleh semua organisme fotosintetik, serta sejumlah bakteri dan jamur non-fotosintetik. Ada dua pengelompokan karotenoid alami: (1) karoten, seperti â-karoten dan á-karoten, dan (2) santofil. Umumnya santofil seperti violasantin, antherasantin, zeasantin, neosantin, dan lutein diproduksi oleh tumbuhan tingkat tinggi, namun juga dapat disintesis oleh mikroalga hijau. Zeasantin merupakan salah satu pigmen yang berperan penting dalam pencegahan penyakit degenerasi makular akibat usia (AMD). Produksi zeasantin dapat dilakukan oleh beberapa mikroalga seperti Spirulina sp., Dunaliella salina, Chlamydomonas reinhardtii, Synechocystis, Microcystis aeruginosa, dan Porphyridium cruentum. Artikel ini akan membahas mengenai biosintesis zeasantin serta pemanfaatannya.

Published: November 2016

The aim of this research was to synthesize a hydrogel for wound dressing by mixing of polyvinyl alcohol (PVA) and chitosan (CTS) and processed by combination technique of freezing-thawing and irradiation by gamma ray, and to study of its properties. PVA aqueous solution 10% (w/v) was mixed with 2% (w/v) chitosan (CTS) solution and homogenized. The PVA-CTS mixture was processed by freezing-thawing up to 3 cycles, and then irradiated by gamma rays at the doseranged of 20-50 kGy (dose rate was 10 kGy/hour). Result showed that PVA-CTS hydrogel with the gel fraction of 83%, 87%, 90%, and 83% were obtained at the irradiation dose of 20 kGy, 30 kGy, 40 kGy, and 50 kGy, respectively. Increasing of irradiation dose caused increasing of water absorption of hydrogel, i.e. 1.700 %, 1.715 %, 1.913 %, and 2.036 %, respectively, and the hydrogel reached the equilibrium in 25 hours. The hydrogel showed very slow water evaporation rate (~ 2%) at the initial time (1 hour) and then increased very fast (up ~50 %) at 24 h, i.e. 43%, 39.13%, 44%, and 53%, respectively. The elongation at break of hydrogels were obtained 245%, 322%, 322%, and 205% with the maximum value were obtained at irradiation dose ranged of 30-40 kGy. The presence of chitosan in the PVA hydrogel made it having higher antibacterial properties with the inhibitionzone value of 8 mm at irradiation dose of 30-40 kGy compared to PVA hydrogel as a negative control (6 mm) and to chloramphenicol as a positive control (8 mm).

Packaging has many functions, e.g. as containment, to protect products from physical damage,and from H2O, O2, and CO2 exposure, as well as to attract the consumers. Based on the technology,packaging can be divided into 3 types i.e. passive packaging, active packaging, and smartpackaging. Modified Atmosphere Packaging (MAP) is the most common active packaging foundin the market. MAP has been used to extend the shelf life of several fish such as raw whiting (codfamily), mackerel, salmon fillet, cod fillet, fresh bluefin tuna fillet, etc. MAP which was combinedwith freeze-chilling has been proved to extend the shelf life of raw whiting, mackerel, and salmonfillet. MAP also increased cod fillet’s shelf life up to 20 days, whiting fillets packed in 100% CO2and stored at 4°C temperature up to 15 days. MAP combined with antioxidant on fresh bluefin tunafillets stored at 3°C for 18 days was able to extend products shelf life from 2 days (control) to 18days, meanwhile 100% N2 in packaging has protective effect on haemoglobin and lipid oxidation.Packaging innovations and ingenuity will continuously develop MAP that is oriented for consumer,enhance the product, environmentally responsive, friendly, and cost effective.
DEVELOPMENT OF REAL TIME POLYMERASE CHAIN REACTION FOR DETECTION OF Salmonella typhimurium AND Salmonella enteritidis IN FISH
Authors: Siregar Tuti Hartati , Elliman Jennifer , Owens Leigh 
Published: November 2016

Previously designed endpoint PCR has been adapted for use with real time PCR to detect the presence of Salmonella typhimurium and Salmonella enteritidis in fish. Optimization of a standard curve in the presence of herring sperm DNA as background matrix indicated that the real time PCR highly efficient with the Pearson coefficient of determination (R2) value = 0.99937 and slope (M) value = -3.44. An enrichment method (overnight culture) significantly increased (p<0.05) the sensitivity of real time PCR. Comparison of real time PCR and the conventional isolation method based on biochemical tests has been conducted. In terms of their sensitivity, real time PCR and the conventional methods are not significantly different in the level of confidence 95%. Both real time PCR with enrichment method and conventional biochemical method can detect the presence of Salmonella spp. in spiked sample. However the direct extraction method was only detecting the presence of Salmonella in higher concentration. While the sensitivity both conventional and real time PCR are similar, the real time PCR has an advantage to detect the pathogen qualitatively and quantitatively depending on processing method.
Synthesis of a Bio-Polymer Nanocomposite Fracturing Fluid for HTHP Application
Authors: Chauhan Geetanjali , Ojha Keka 
Published: November 2016

Abstract
The global energy demand has been amplified significantly in the last two decades and the Oil & Gas industry turns to harsh operating conditions of high pressure high temperature (HPHT) and brine. The present study proposes biopolymer nanocomposite as a solution to these challenges in fracturing application as the resultant fracturing fluid possess synergetic and hybrid properties of polymer and nanoparticles which offers unique mechanical and thermal properties. Nano composites formed with biodegradable polymers have high rewards and opportunities in the future for the applications in the design of environmental friendly materials. The developed nanocomposite fluid can solve the breaking residue problem associated with guar and can give viscosities similar to guar with benefits of bio-degradability. The nanocomposite fluid provided viscosities above 100cP at 100s−1 shear rate upto 150oC at 1.75% polymer concentration with 0.5% SiO2 nanoparticle. The oscillatory study reveals true gels characteristics with G̍/G̎ ratio &gt;3. The elastic behavior was dominated by viscous behavior which supports proppant suspension capability. The nanocomposite fluid was easily breakable using oxidative breaker-Ammonium per Sulfate and residue generated was less as compared to guar gum due to lower molecular weight without compromising on viscosity. The static proppant suspension test showed satisfactory performance making it suitable for HTHP conditions.
