Interwell connectivity analysis in a low-permeability formation using a modified Capacitance Model with application to the East Pembina Field, Cardium Formation, Alberta
Authors: Mirzayev Mammad , Jensen Jerry L. 
Published: March 2019

From the 1950s to the present, the Cardium Formation has been extensively produced. Exploitation has moved from the high-permeability western areas to very heterogeneous lower permeability, “halo-oil” regions in the east. In this case study, we briefly summarize the geology and assess the degree of interwell communication in selected areas from the East Pembina Field. For the Interwell Connectivity (IWC) evaluation, we use a modified version of the Capacitance Model (CM-PW) for connectivity analysis in areal windows. The CM has been used to analyze flow rates to measure IWC. The direction of the largest IWC change agrees with the expected maximum stress direction in the Western Canada Sedimentary Basin. The model also captures differences between pre- and post-fracturing connectivities. The matches of predicted to measured production using the CM-PW are fair to good, 0.76 ≤ R2 ≤ 0.95.

Authors: Hill Callie Roberts , Wang Apphia , Elewski Boni E. , Pavlidakey Peter G 
Published: March 2019

Subcutaneous panniculitis-like T-Cell lymphoma (SPTCL) is a rare subtype of cutaneous T-cell lymphoma, and it has been associated with a range of clinical symptoms from mild to severe. Most commonly, this disease is described as following a slowly progressing course, associated with vague constitutional symptoms and good prognosis. This case report describes the clinical presentation and findings of SPTCL in a 31 year old female and describes the challenges of recognizing and properly diagnosing this disease. SPTCL has been described as a mimicker of other, more common and nonmalignant diseases of the skin, such as lupus panniculitis. This report highlights a variety of specific tests including immunohistochemical and immunoperoxidase staining, as well as genotypic analysis of T-cell receptors, that were effective in combination in isolating this diagnosis. Moreover, choice of treatment for these patients can be challenging, as an array of interventions have been described in past cases to treat SPTCL. This report recognizes the efficacy of a treatment course that included a six-cycle course of combined chemotherapy (vincristine, doxurubicine, cyclophosphamide, and prednisone, also known as CHOP) followed by weekly methotrexate and PET scan surveillance for two years. With both initial and maintenance therapy, this patient showed excellence response evidenced by a progressive decrease in metabolic activity of malignant lesions, lack of new lesions, and remaining without symptoms. While this disease is rare, it is important to include SPTCL in the differential when considering patients with a panniculitic picture.

Commercial wireless versus standard stationary EEG systems for personalized emotional brain-computer interfaces: a preliminary reliability check
Authors: Buchanan Derrick Matthew , Grant Jeremy , D'Angiulli Amedeo 
Published: March 2019

We present a preliminary data-based assessment of measurement reliability of the commercial 14-electrode Emotiv EPOCTM EEG wireless system in distinguishing between electrophysiological states of emotional function, as compared to a standard research-lab stationary 32-electrode EEG system for personalized single-individual use. Individual observers completed two tasks designed to elicit neural changes in emotional arousal and valence while simultaneously recording their EEGs with both systems in separate sessions. Participants observed emotion-laden words from the ANEW database and images from the IAPS database, both widely used and validated databases for emotional processes in multidisciplinary research. The pattern of results distinguished between high and low arousal and valence states using the stationary traditional system, but not the commercial device. Also, the latter device recorded EEG band frequencies at a much lower resolution and frequency range than the standard system. These findings suggest poor validity when using the commercial device and therefore should be cautioned against in a research setting.

Sodium Lauryl Sulfate vs. Sodium Coco Sulfate. Study of the Safety of Use Anionic Surfactants with Respect to Their Interaction with the Skin
Authors: Bujak Tomasz , Nizioł-Łukaszewska Zofia , Wasilewski Tomasz 
Published: March 2019

AbstractAs a result of growing awareness, consumers are increasingly interested in products that are safe on the skin and environmentally-friendly. This is one of the most important reasons for the very rapid development of the natural cosmetics segment which has been observed for several years now. Among the most commonly used anionic surfactants of natural origin are sodium lauryl sulfate (SLS) and sodium coco sulfate (SCS). As there are no unambiguous reports on the safety of using SCS, in this study an attempt was made to evaluate the effect of SCS on the skin. The results of the determination of the skin irritation potential (zein value) indicate that the analyzed parameter is approximately 15 % lower in SCS than in SLS. SCS has a stronger ability to interact with epidermal lipids and cause their elution from the skin, which in turn may damage the protective epidermal barrier. The results obtained during the evaluation of the effect produced by the analyzed substances on the metabolism of human keratinocytes (HaCaT) show that after 4 h of incubation with the studied groups of compounds there was a significant decrease in cell proliferation. The highest decrease in cell metabolism was demonstrated for SLS.
Viscometric Studies of Cu(II) Surfactants Derived from Mustard Oil in Benzene at 303.15 K
Authors: Tank Pragya , Sharma Rashmi , Sharma Arun Kumar 
Published: March 2019

AbstractThe viscosity, specific viscosity, and fluidity of Cu(II) surfactant complexes derived from mustard oil with urea/thiourea/2-amino-6-chloro benzothiazole in a non-aqueous solvent has been determined at a constant temperature of 303.15 K. The results were used to determine the critical micelle concentration (CMC), soap complex-solvent interactions and the effect of chain length of the surfactant molecule on various parameters. The conclusions with regard to solute-solute and solute-solvent interaction have been discussed in terms of well-known Moulik and Jones-Dole equations. The effect of surfactant concentration on the viscosity of the solution in non-polar solvent has been discussed. The observations suggested that the structure breaking effect by the solute on the solvent molecules is more prominent above CMC as compared to below CMC after the formation of the micelles. This information plays a role in various industrial and biological applications.
Evaluation of Fabric Softener Formulations with High Concentrations of Cationic Surfactant
Authors: Ogorzalek Marta , Wasilewski Tomasz , Klimaszewska Emilia 
Published: March 2019

AbstractThe study was an attempt to develop fabric softener formulations with a markedly higher content of active substances compared to traditional products. The assumption was to design the formulations in such a manner as to eliminate problems associated with the application of cationic surfactants at high concentrations, and to obtain products exhibiting a high level of quality (products characterized by functionality and usability expected by consumers). The selection of magnesium chloride concentration in products of this type was found to be related to the desired product concentration. It was also demonstrated that by adding salt to concentrated fabric softeners, it is possible to regulate their viscosity and dissolution time in water, and also reduce the viscoelastic properties which are undesirable in the process of manufacture of such products.

AVALIAÇÃO MORFOLÓGICA E ELEMENTAR DE MATERIAIS CARBONÁCEOS DE MADEIRA DA INDÚSTRIA DE CARBONO ATIVADA A preocupação mundial na redução dos gases de efeito estufa para a atmosfera, combinada com leis ambientais mais rigorosas, tem levado a um aumento dos estudos sobre a energia renovável. Esta pesquisa teve como objetivo caracterizar lascas de madeira e carvão ativado por microscopia eletrônica de varredura (MEV) e espectroscopia de energia dispersiva (EDS). Os cavacos são oriundos de uma floresta de Pinus elliottii voltada para fins energéticos e foram queimados em uma fornalha de uma caldeira de geração de vapor. Esse vapor gerado pela caldeira em fornalhas apropriadas é utilizado na ativação de carvão vegetal por pequenos produtores regionais. MEV indicou um aumento na porosidade do carvão vegetal com o processo de ativação, e a análise EDS indicou que tanto os cavacos quanto os carvões, com e sem ativação, não apresentaram contaminantes, como os metais pesados. Este estudo revelou uma baixa toxicidade dos materiais lignocelulósicos à base de Pinus elliottii. A queima de cavacos de madeira na caldeira e o processo de ativação de carvão vegetal não apresentaram riscos ambientais.Palavras-chave: energia florestal, carbonização, carvão ativado, metais, porosidade. ABSTRACT: The worldwide concern of reducing greenhouse gases into the atmosphere combined with more stringent environmental laws has led to an increase in studies of renewable energy. This research aimed to characterize wood chips and activated charcoal by scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). The chips came from an energy forest of Pinus elliottii and were burned in the furnace of a boiler for steam generation. This steam generated by the boiler in appropriate furnaces is used in the activation of wood charcoal from small regional producers. SEM showed an increase in the porosity of the charcoal with the activation process, and EDS analysis indicated both chips and charcoals, with and without activation, have no contaminants, such as heavy metals. This study revealed a low toxicity of lignocellulosic materials based on Pinus elliottii. The burning of wooden chips in the boiler as well as the activation process of wood charcoal did not present apparent environmental risks.Keywords: forestry energy, carbonization, activated carbon, metals, porosity.

O objetivo do presente trabalho é caracterizar biometricamente os frutos e sementes de Passiflora cristalina Vanderplank & Zappi ocorrentes na região de Alta Floresta, Mato Grosso. Foram coletados em 2013 um total de 100 frutos maduros de 15 genótipos e destes foram selecionadas 300 sementes aleatoriamente. Os frutos foram analisados quanto ao comprimento, largura, espessura, peso, espessura da casca, o peso da polpa, o peso das sementes/fruto, número de sementes/fruto e teor de sólidos solúveis. As sementes foram avaliadas em relação ao comprimento, largura, espessura e índice de volume. As características biométricas foram analisadas mediante distribuição de frequência calculando-se o coeficiente de correlação de Spearman e o nível de significância através do teste T. O comprimento do fruto correlacionou-se positivamente com a largura e peso do fruto, espessura da casca e com peso das sementes, não havendo uma correlação com o número de sementes por fruto. Houve uma ampla distribuição de frequência das características avaliadas nos frutos, com exceção do peso das sementes. A alta variação fenotípica encontrada para a maioria das características avaliadas nos frutos e sementes de P. cristalina revela que a espécie tem divergência genética a ser utilizado em programas de seleção e conservação de recursos genéticos.Palavras-chave: divergência genética, maracujá, recursos genéticos.
