Abstract
This paper presents the results of remote acidizing treatments performed in 7 injection wells of the Marlim Field, which is responsible for 35% of the Brazilian oil production. In recent years, solids and rust from the seawater injection process have severely reduced the injectivity of the wells. However, the high costs involved and the limited availability of dynamically positioned rigs required for conventional treatments have prevented the restoration of the injectivities and, consequently, the production of adjacent wells had to be restricted. The advent of remote operations using stimulation boats anchored to production platforms, whose application on a production well was described on a previous paper1, provided a simple, efficient, and economical solution to the problem, since all treatments were operationally and economically successful, resulting in a total increase in the water injection rate of 6613 m3/d. In addition, the paper presents laboratory experiments that have been conducted to verify the influence of the acids (HF and HCl) upon the flexible flowline, wellhead equipment and the string's metals, which have shown that pumping acid remotely was safe. The technique developed can be applied to other deepwater offshore fields and ongoing research is being performed in other to extend it to different situations, such as production and/or gravel packed wells, where acid diversion plays a major role in the operation's success and spent acid may cause even more severe corrosion problems.

Published: December 2016

ABSTRACT: Sludge settling and thickening occur simultaneously in secondary settling tanks (SSTs). The ability to accurately calculate the settling and thickening capacity of activated sludge was of great importance. Despite extensive studies on the development of settling velocity models for use with SSTs, these models have not been applied due to the difficulty in calibrating the related parameters. Additionally, there have been some studies of the thickening behavior of the activated sludge in SSTs. In this study, a novel settling and thickening model for activated sludge was developed, and the model was validated using experimental data (R2 = 0.830 to 0.963, p < 0.001), which is more reasonable for the characterization of the settling and thickening behavior of the activated sludge in an SST. The application of these models requires only one critical parameter, namely, the stirred sludge volume index SSVI3.5, which is readily available in a water resource recovery facility.

Published: December 2016

ABSTRACT: In this study, a laboratory‐scale anammox process in a membrane bioreactor (AnMBR) was used to startup the anaerobic ammonium oxidation (anammox) process from conventional activated sludge. Stable operation was achieved after 125 days. From that time, nitrogen load was gradually increased. After six months, the average nitrogen removal efficiency exceeded 80%. The highest obtained special anammox activity (SAA) achieved was 0.17 g (‐N + ‐N) (g VSS × d)−1. Fluorescent in situ hybridization also proved the presence of the anammox bacteria, typically a genus of Brocadia anammoxidans and Kuenenia stuttgartiensis.

Published: December 2016

ABSTRACT: Modeling and optimization tools play a key role in membrane fouling control in membrane bioreactor (MBR) systems by delineating the more important variables involved. In this study, the influence of sludge retention time (SRT), aeration rate and filtration mode on hollow fiber membrane fouling was investigated. Using the response surface methodology (RSM) for modeling and central composite rotatable design (CCRD) for design of experiments, mathematical models were developed for fouling rate and protein (P1, P2) and carbohydrate (C1, C2) concentrations in two layers of fouling. Results showed that sludge retention time (SRT) was the most important variable in most models followed by aeration rate. Aeration showed a more effective role on the models of the rinsed layer (P1, C1) than backwashed layer (P2, C2). Backwashed layer had more influence on total fouling rate than rinsed layer. The optimal point for MBR operation was: SRT = 30 days, aeration = 10.7 L/min, relaxation interval = 8.8 minutes, and relaxation duration = 41.8 seconds.
Effect of Combination Therapy with Atorvastatin and Ursodeoxycholic Acid on the Course of Ischemic Heart Disease with Co-Existent Non-Alcoholic Fatty Liver Disease and Obesity
Authors: Karpyshyn Nataliya 
Published: December 2016

Non-alcoholic fatty liver disease is considered as an independent predictor of cardiovascular diseases which plays an important role in the development of ischemic heart disease. The drug most frequently used for treating this comorbidity is atorvastatin which favours better survival outcomes and is essential in the primary and secondary prevention of cardiovascular diseases. Ursodeoxycholic acid is prescribed as an alternative therapy for ischemic heart disease with co-existent non-alcoholic fatty liver disease and obesity to eliminate statin side effects. The use of ursodeoxycholic acid as a hepatoprotector in comprehensive basic treatment contributes to the improvement of the cardiovascular system in patients with ischemic heart disease as well as the increase in treatment efficacy; it improves the functional status of the liver affecting the major pathogenic mechanisms of the disease.The objective of the research was to study the effect of combined hypolipidemic therapy with atorvastatin and ursodeoxycholic acid on the indices of blood lipids, liver transaminase levels, functional status of the liver and the course of non-alcoholic fatty liver disease in patients with ischemic heart disease and obesity.Materials and methods. 20 patients with ischemic heart disease, co-existent non-alcoholic fatty liver disease and obesity were examined. They received ursodeoxycholic acid in addition to atorvastatin for four weeks. All the patients underwent clinical tests, visceral ultrasonography, blood lipid test, liver transaminase test and 13C-methacetin breath test.Results. The study revealed a significant decrease in the level of the pro-atherogenic fractions of blood lipids (р<0.01) as well as an improved functional status of the liver due to a significant increase in metabolic capacity of the liver and cumulative dose on the 40th and 120th minutes after ursodeoxycholic acid administration (р<0.01).Conclusions. The use of ursodeoxycholic acid in addition to atorvastatin in patients with ischemic heart disease, co-existent non-alcoholic fatty liver disease and obesity makes it possible to avoid the adverse effect of hypolipidemic therapy on the functional status of the liver.

Los orígenes de una estrella: las comedias iniciales de Zully Moreno
Authors: Pardo Soledad 
Published: December 2016

Zully Moreno fue una de las principales estrellas del cine clásico argentino, asumiendo en su persona un número de cualidades entre las que destacaban el glamour, la belleza, el carácter y una marcada sexualidad. A diferencia de otras estrellas contemporáneas, su carrera no fue fulgurante desde un inicio, sino que comenzó a partir de pequeños roles para ir ganando gradualmente lugares más destacados. Este primer momento de su filmografía fue mayoritariamente en el terreno de la comedia sofisticada, donde comenzó a desarrollar el texto estrella que luego asumiría como propio.
En el presente artículo nos proponemos abordar ese primer conjunto de películas en las que trabajó la estrella para analizar cómo se produce en ellas una proto-configuración de su futuro rol y del tipo de mujer que encarnaría en su carrera. Para ello consideraremos en primer lugar el perfil psicológico de sus personajes y su relación con la ‘joven moderna’, un prototipo de mujer que se encontraba en discusión en el campo cultural del período. En segundo lugar, ahondaremos en los distintos elementos de la puesta en escena que colaboraron en la conformación de su imagen. Por último, nos detendremos en el modo en que los paratextos cinematográficos fueron delineando su gradual ascenso y la constitución de su figura.

Authors: Cunha Paulo , Araújo Helyenay 
Published: December 2016

Com escassos recursos e um mercado interno muito limitado, a produção de cinema em Portugal é muito marcada pela grande dependência dos apoios públicos à produção. Se o cinema português, salvo raras excepções, já pode ser considerado todo ele como sobrevivendo numa lógica de produção de baixo orçamento, como se poderá classificar a produção de cinema da Guimarães 2012 Capital Europeia da Cultura que, em cerca de dois anos, conseguiu produzir aproximadamente 50 filmes com um orçamento total de US$ 4 milhões?
O objectivo deste texto, para além de debater a categoria de cinema de baixo custo no contexto português, é conhecer e caracterizar o projecto de produção de cinema da Guimarães 2012 Capital Europeia da Cultura como caso de estudo, procurando compreender as vicissitudes do novo modelo de produção proposto nesse contexto e reflectindo sobre a sua viabilidade para o futuro de uma cinematografia de pequena dimensão como a portuguesa.

Authors: Nahata Manak 
Published: December 2016

Community ophthalmology deals with all aspects of vision covering a wide range of fields for work – Prevention of blindness, conservation of sight, social service, promotion of employment, rehabilitation and recreation of the blind. Community ophthalmology is attracting the attention of ophthalmic world. This delivery of eye care involves preventive, curative, promotive and rehabilitative activities incorporating basic clinical and public health sciences in all its dimensions. It highlights the realignment from individualized care to community based eye care services. Community ophthalmology is seen as a health management approach in preventing eye diseases, lowering eye morbidity or eye morbidity rates and promoting eye health through active community participation at the ground level. Comprehensive eye care services must start where people live and work and such is the thrust of community ophthalmology. Prevention and promotion should begin amongst the people.

Published: December 2016

Introduction: An understanding of the expectations and attitude of patients is a prerequisite for appropriate behavioural and clinical management.Objective: To assess patients’ expectations of orthodontic treatment and relationship of gender to this expectation among Nigerian patients.Materials & Method: The descriptive study comprised of patients attending the orthodontic clinic at Lagos State University Teaching Hospital (LASUTH), Nigeria for the first time. A structured questionnaire was used to obtain the socio-demographic information and responses to questions on their expectation of orthodontic treatment.Result: Majority of the respondents had higher expectations on aesthetic outcome of orthodontic treatment than the functional outcomes. They expected to have better smile, teeth straightened and have confidence socially. The lowest mean scores were obtained in the domains of improvement in career and making speech easier. Females had significant higher scores than male participants in all domains explored with the mean highest score in the domain of better smiles; while the highest male mean score was in the domain of straightened teeth.Conclusion: Orthodontics relies heavily on patient cooperation for a successful end result. It is recommended that the orthodontist agrees with the patient on realistic expected treatment outcomes before the treatment commences so that they are not disappointed with the final appearance.

The Perversion of Nature: Johannes Baptista Van Helmont, the Society of Jesus, and the Magnetic Cure of Wounds
Authors: Waddell Mark A. 
Published: December 2016

One of the seventeenth century’s most prominent medical reformers, Johannes Baptista van Helmont (1579-1644) was also one of the most controversial figures of his time, thanks to the wide­spread public censure inspired by his 1621 treatise on the magnetic cure of wounds. Van Helmont defended his work by claiming that it had been illicitly published, without his permission, by a member of the Society of Jesus, Jean Roberti (1569-1651). This paper will attempt to place Van Helmont’s accusation against Roberti within the wider intellectual and cultural context of the period, which saw the definition of nature become increasingly more fluid and open to a variety of novel interpretations. Since its inception, the Society of Jesus had embraced a variant of the long-lived Scholastic philosophy as its primary focus in both natural philosophy and pedagogy. At the same time, a wide­spread movement against Scholasticism prompted the creation of entirely new philosophies of nature. Van Helmont’s work on the magnetic cure of wounds advanced a philosophical system at odds with the Scholastic physics codified in the institutional and pedagogical practices of the Society, and simultaneously challenged the Society’s right to participate in the natural philosophical culture of the time. Though direct proof for Roberti’s illicit publication of Van Helmont’s work is lacking, an examination of the rich context surrounding this particular encounter can better explain Van Helmont’s accusation of interference levelled against a member of the Society.
Biblical Parallels in Political Rhetoric: A Case Study of Writings by Ukrainian Hetmans, Their Entourages, and Contemporaries (1640s-70s)
Authors: Shiyan Roman I. 
Published: December 2016

This paper explores ideology in seventeenth-century Cossack Ukraine by analyzing the use of religious motifs in political rhetoric from the late 1640s to the late 1670s — a time offoreign invasions and internal power struggles. Based upon the premise that the major factor affecting the incorporation of religious motifs into secular political discourse was the general religiousness of public and private life during that period, this paper investigates how and for what purposes specific biblical motifs were employed. Religious motifs were used for political purposes by various parties, all of whom belonged to the same cultural-religious space or were familiar with Bible narratives. Agendas and approaches, however, varied. The educated clergy and laity used more developed motifs in a more eloquent presentation, aimed at other educated clergy and laity as their main audiences. In contrast, manifestos with less elaborate use of biblical references and religious motifs issued to the general public, as well as letters by some Cossack officers, served utilitarian propaganda purposes.
US-Romanian Relations during the Presidency of Gerald R. Ford
Authors: Mount Graeme S. 
Published: December 2016

Throughout Gerald Ford’s presidency (9 August 1974-20 January 1977), the Romanian government of Nicolae Ceauşescu was one of the most totalitarian governments of Communist Europe. Yet, President Ford and Secretary of State Henry Kissinger had a friendly personal relationship with Ceauşescu, primarily in the hope that he would help to undermine the Soviet Empire. Kissinger had limited interest in democratic practices outside the United States, and Ceauşescu’s Stalinist tendencies were of limited concern to him. Ceauşescu sought to use the United States as a counterweight to the Soviet Union and to gain economic benefits for Romania. Ford and Kissinger were willing to grant Romania most favored nation (MFN) status, but Congress had reservations. Would Romanian Jews have the right to emigrate? Would Ceauşescu’s government respect the language “rights” of Transylvania’s ethnic Hungarians and Germans? Would Romania’s Protestants and Roman Catholics enjoy freedom of worship?
Removal of Pb and Zn from industrial effluent using humic acid
Authors: Parvin A , Hoque S 
Published: December 2016

The present work was conducted to remove Pb and Zn from industrial effluents by coagulating the ions with humic acids. Seven types of effluents were collected from textile, tannery and pharmaceutical industries. Two commercially available humic acids one in a liquid state and another one in a semi-solid state, humic acid extracted from peat were used to remove Pb and Zn from industrial effluents as well as synthetic waste water. Optical property, carbon concentration and coagulation threshold of humic acids were studied. Same carbon concentration (1 x 10-5 g L-1) of all the sources was maintained at neutral pH. The values of water soluble Pb and Zn in effluents were 0.000 - 0.0711 ?g/mL and 0.002 - 0.024 ?g/mL, respectively. Results indicated that liquid humic acid having E4: E6 ratio of 1.2 removed 100% Pb and Zn only from pharmaceutical effluent whereas humic acid extracted from peat having E4: E6 ratio of 3.18 completely (100%) removed these metals from pharmaceutical and tannery effluents. Semi-solid humic acid having the lowest E4: E6 ratio of 1.07 did not form coagulation with the metals. The performance of humic acid extracted from peat was better than that of commercially available humic acids. Bangladesh J. Sci. Ind. Res. 51(4), 279-284, 2016
