Published: March 2017

The reserves of Coalbed Methane (CBM) in Qinshui Basin are quite promising, but the outputs from CBM wells are quite small even after massive hydraulic fracturing. Herein the fracture system with #3 and #15 coal seams in Qinshui basin was analyzed, and it was found that both of the macro-scale fractures and micro-scale fractures are filled with clay and carbonate minerals, which explains the low productivity of CBM wells after conventional hydraulic fracturing. Acid fracturing has long been an effective method for carbonate gas reservoir to improve the gas well production. However, there were few reports about the application of acid fracturing in coal bed methane field. Based on the mineral identification and acid sensitivity test, the feasibility of acid fracturing demonstrated that the acid does more help than damage to increase the permeability of coal seams in Qinshui basin. Onsite operations have shown that acid fracturing is applicable for the CBM wells in Jincheng Mining Area. It was also observed from the microseismic survey that when applying the acid fracturing treatment, the stimulated reservoir area depends on the acid volume pumped in the first stage, which is crucial to the success of the stimulation. Evaluación piloto de fractura ácida en depósitos de gas metano de carbón en el suroeste de la cuenca Qinshui, China ResumenLas reservas de gas metano de carbón (CBM, del inglés Coalbed Methane) en la cuenca Qinshui son más que prometedoras, pero la producción en los pozos es muy pequeña, incluso después de fracturas hidráulicas masivas. En este trabajo se analizaron los sistemas de fractura de las vetas de carbón #3 y #15 de la cuenca Qinshui y se encontró que tanto las fracturas a macroescala como aquellas a microescala están cubiertas con arcillas y minerales carbonatos, lo que explica la baja productividad de los pozos de gas metano de carbón después de la fractura hidráulica convencional. La fractura ácida ha sido un método efectivo en los depósitos de gas carbonato para mejorar la producción en el pozo de gas. Sin embargo, existen pocos informes sobre la aplicación de la fractura ácida en el campo del gas metano de carbón. De acuerdo con la identificación mineral y las pruebas de sensibilidad ácida, la factibilidad de la fractura ácida demostró que el ácido es reparador en el incremento de la permeabilidad en las vetas de carbón de la cuenca Qinshui. Las operaciones in situ han demostrado que la fractura ácida es aplicable para los pozos de gas metano de carbón en el área minera de Jincheng. También se observó en el sondeo microsísmico que cuando se aplica un tratamiento de fractura ácida, el área del depósito estimulada depende del volumen de ácido bombeado en primera instancia, lo que es determinante en el éxito de la estimulación.
El lenguaje místico y la inefabilidad
Authors: Barbosa Cepeda Carlos 
Published: March 2017

¿Por qué el místico pretende hablar sobre aquello de lo cual, según él mismo, no se puede hablar? Se analiza el lenguaje místico en términos pragmáticos, para mostrar cómo busca expresar lo que no se puede caracterizar, lo que supone distinguir entre decir como caracterizar y decir como dar expresión. Esta diferencia es posible, según Chien-Hsin Ho, por la operación de indicar lo inefable mediante la superimposición con negación, y porque la indicación no apunta a lo trascendente, sino a lo inmanente del lenguaje mismo.

Published: March 2017

Studi ini dimaksudkan untuk menginvestigasi karakteristik dan model matematika kurva pengeringan rumput laut Eucheuma cottonii. Hasil penelitian ini diharapkan dapat digunakan untuk perancangan alat pengering rumput laut yang efisien. Pengeringan E.cottonii dilakukan dengan menggunakan alat pengering laboratorium terkendali yang dilengkapi dengan sistem akuisisi data dengan kecepatan udara 0,5 m/detik. Empat variasi RH yang dilakukan pada suhu 50 °C adalah 30%, 40%, 50% dan 60% serta empat variasi suhu yang dilakukan pada RH 40% adalah 40 °C, 50 °C, 60 °C dan 70 °C. Tiga model pengeringan yang diuji adalah model Newton, Henderson & Pabis dan Page. Simulasi model yang paling tepat ditentukan berdasarkan nilai R2 yang paling tinggi, serta nilai sum square error (SSE) dan root mean square error RMSE yang paling rendah. Laju pengeringan lapis tipis rumput laut E.cottonii umumnya berada pada periode laju menurun. Hal ini sesuai dengan karakteristik pengeringan bahan-bahan biopolimer yang umumnya berlangsung dengan laju menurun. Hasil penelitian menunjukkan bahwa penurunan RH cukup efektif dalam menurunkan kadar air dibandingkan peningkatan suhu. Pada RH rendah yaitu 30% suhu 50 °C, penurunan kadar air 50% dicapai dalam waktu 80-85 menit jauh lebih cepat dari RH 60% suhu 50 °C yaitu 165-170 menit. Pada suhu tertinggi yaitu 70 °C RH 40% penurunan kadar air 50% dicapai dalam waktu 90 menit selisih 15 menit lebih cepat dibandingkan suhu terendah yaitu 40 °C RH 40%. Kajian ini mendapati model pengeringan E.Cotonii yang paling sesuai adalah model pengeringan Page dengan nilai R2, R2 terkoreksi, SSE and RMSE berturut-turut sebesar 0,98-0,99 ; 0,96-0,98 ; 0,0002-0,0126 dan 0,0002-0,0206.

The Macroeconomic Effects of German Fiscal Austerity under Different Exchange Rate Regimes: The Experience of Central and Eastern European Countries
Authors: Shevchuk Viktor , Kopych Roman 
Published: March 2017

According to a familiar two-country Mundell-Fleming framework, the policy of fiscal austerity in Germany should be restrictionary for other European countries with a floating exchange rate, while there is a possibility of an expansionary effect for countries with a peg. Using quarterly data of eight Central and Eastern European countries over the 2002–2014 period, it is found with a four-variable VAR model that fiscal austerity in Germany leads to an increase in the money supply and output, while the effects on the real exchange rate are marginal. Our results contrast with several other studies, that imply that the policy of fiscal stimulus in Germany is beneficial for other European countries. Our results could be interpreted in such a way that demand and competitiveness effects are outweighed by the effect of international flows. A strongest expansionary effect is obtained for Bulgaria, Slovakia and Latvia, which maintain fixed exchange rates, while expansionary effects are weaker for countries with greater exchange rate flexibility, such as Poland, Hungary and the Czech Republic.

A Necessária Desconstrução da Colonialidade nas Amazônias e nas Américas
Authors: Neves Lino João de Oliveira 
Published: March 2017

Como faces articuladas do longo processo de Conquista a que foram/são submetidos os povos indígenas nas Américas, “Colonização”, “Colonialismo” e “Colonialidade” são conceitos de uso corrente, muitas vezes empregados de maneiras impróprias. Desconstrução da colonialidade é o movimento necessário e urgente de desconstruir as múltiplas situações de colonialismo que ainda hoje
submetem o viver de grande parte da população nas Amazônias e nas Américas. Desconstruir a colonialidade é reconhecer a efetividade dos povos indígenas e seus respectivos sistemas de produção de conhecimento não apenas como “resistências” à invasão-colonização dos mundos indígenas, mas também pelo aporte que podem trazer para o aprimoramento das relações interculturais desde que destituídas do ranço colonial que ainda hoje orienta as relações dos Estados e sociedades nacionais com os povos indígenas.

Published: March 2017

Aborda-se neste artigo a temática do deslocamento internacional de populações de países pertencentes à Pan-Amazônia, em especial as implicações desse fenômeno nas relações familiares enfocando a perspectiva das mulheres guianenses. Buscouse identificar arranjos familiares, vivências transnacionais e demais estratégias que permeiam os vínculos familiares durante o processo migratório.
Utilizou-se a metodologia qualitativa, com ênfase na observação participante, entrevistas abertas e conversas informais. As narrativas dos interlocutores sobre as mulheres guianenses demonstram a
existência de vulnerabilidades relacionadas à cor da pele, etnia e classe social. O processo migratório lhes demanda a construção de atitudes e comportamentos considerados adequados para lidar
com as novas dinâmicas encontradas na localidade hospedeira, a possibilidade de quebra de modelos ideais, a ressignificação dos papéis familiares e o estabelecimento de novos arranjos na família.

<p><em>A</em><em>bstract</em>— Recognizing human hand gesture through the use of INS (Inertial navigation System) sensor, Hidden Markov Model (HMM) was used as a tool to recognize pattern statistically. Employing INS sensor to admit data input , it is assumed that hand gesture could be detected by analizing the acceleration and fluctuation from data sensor and the difference of hand-position in 3-axis. The INS sensor that was being used was came with 6 channels to generate signals of a 3-axis gyroscope and a 3-axis accelerometer. The acceleration fluctuated in three perpendicular directions due to different hand gestures was detected by the accelerometer, while the change of hand-position in 3-axis was detected by gyroscope. Data from sensor was exported to computer via USB (Universal Serial Bus) port.</p><p class="Abstract">During the stage of data collection, a cut algorithm was developed to pick the most significant part of the sensor data. After finishing data comparison stage, DCT (Discrete Cosine Transform) was selected to transform the signal from time domain to frequency domain.

Authors: Gondwe Kaboni Whitney , Yang Qing , White-Traut Rosemary , Holditch-Davis Diane 
Published: March 2017

AbstractPurpose: Multiple preterm birth is associated with more maternal psychological distress and less positive mother–infant interactions than singleton preterm birth. This study’s purpose was to compare psychological distress and the relationship with their infants in mothers of multiples and mothers of singletons.Design: An exploratory secondary analysis of longitudinal data.Sample: 236 mothers and their preterm infants.Main outcome variables: Maternal psychological distress (depressive symptoms, anxiety, posttraumatic stress [PTS], parenting stress), the mother–infant relationship (worry; child vulnerability; maternal positive involvement and developmental stimulation; and child developmental maturity, irritability, and social behaviors), and the home environment.Results: Mothers of multiples had greater PTS symptoms at baseline, anxiety at discharge, and depressive symptoms at six months than mothers of singletons. Mothers of multiples also had more positive home environments at six months. Multiple birth was a risk factor for psychological distress but not for less positive mother–infant interactions.

Published: March 2017

Objectives. To assess the proportion of electronic cigarette (e-cigarette) products sold in the United States that contain nicotine according to retail scanner data. Methods. We obtained unit sales data from January 11, 2015, to December 12, 2015, from The Nielsen Company for convenience stores; supermarkets; mass merchandisers; drug, club, and dollar stores; and Department of Defense commissaries. The data did not include purchases from tobacco specialty shops, “vape shops,” or online sources. Nicotine content was assessed by product type (disposables, rechargeables, and refills), region, and flavor status based on nicotine strength listed in the Universal Product Codes. For the 36.7% of entries lacking nicotine content information, we conducted Internet searches by brand, product, and flavor. Results. In 2015, 99.0% of e-cigarette products sold contained nicotine, including 99.0% of disposables, 99.7% of rechargeables, and 98.8% of refills. Overall, 98.7% of flavored e-cigarette products and 99.4% of nonflavored e-cigarette products contained nicotine. Conclusions. In 2015, almost all e-cigarette products sold in US convenience stores and other assessed channels contained nicotine. Public Health Implications. Findings reinforce the importance of warning labels for nicotine-containing products, ingredient reporting, and restrictions on sales to minors.
