Abstract
This paper discusses installation of the longest high-performance (HP) and rotating 11-3/4" expandable liner on the Elgin field in the Central-North Sea sector of the UK that enabled isolating weak layers in the overburden formations on EIE well, providing sufficient mud weight window to permit drilling high pressure and gas bearing zones. The planning and execution of this record presented challenges beyond those encountered in standard well conditions due to narrow mud weight window (NMWW) and critical requirement of zonal isolation.
EIE well was the third of the 2015-2017 infill campaign on Elgin field. The well faced major challenges in the 12-1/2" section due to the NMWW which triggered the deployment of the contingent well architecture with HP 11-3/4" expandable liner. This critical requirement of zonal isolation significantly impacted the preparation and risk assessment of expandable liner operations. A new expansion assembly design was implemented to allow rotation of the 11-3/4" size system to improve the cement job quality. Moreover, all contingency procedures were significantly modified to ensure that the objective of the specific well constraints were considered.
After under-reaming while drilling 12-1/4" × 14" section down to planned depth, 860m of 11-3/4" liner was run with no open hole problems. This liner was successfully rotated at bottom prior to pumping cement and fully expanded without incident. The system was successfully pressure tested prior to drill-out of the plugs and the shoe assembly was drilled with no issues.
Running of an 860m HP 11-3/4" expandable liner and rotating shoe assembly on EIE well is a record (longest HP string run before was 360m) and considered as a remarkable achievement. However, liner objectives were not fully met and cement squeeze below the shoe had to be performed. Post-job investigation highlighted issues related to dart selection and related cement over-displacement, limited contingences in case of expansion pressure loss, and the ability to pull the liner to surface in a NMWW. These issues remain to be solved for optimisation of future deployments.
This paper provides information on the design and operational aspects that should be considered for expandable liner operations on complex wells with NMWW. Understanding advantages and limitations of the system will open up opportunities to improve the technology and help to reduce operational risk.

Authors: Santos Gleyson Moura dos 
Published: April 2018

A Leishmaniose Tegumentar Americana (LTA) é uma doença causada por protozoários do gênero Leishmania e é transmitida ao homem pela picada do mosquito flebotomíneo. A LTA representa um grande problema de Saúde Pública, pois além da alta incidência e ampla distribuição geográfica, é uma das afecções dermatológicas que merece mais atenção devido à sua magnitude. Este estudo teve como objetivo descrever o perfil epidemiológico e clínico da LTA bem como sua distribuição espacial no estado do Maranhão no período compreendido entre os anos de 2012 a 2015. Trata-se de um estudo descritivo/retrospectivo de base populacional, utilizando dados secundários de casos confirmados LTA registrados no Sistema de Informações de Agravos de Notificação (SINAN) e disponibilizados no site do Departamento de Informática do Sistema Único de Saúde (DATASUS). Foram registrados 8.625 casos, com incidência média de 31,68 casos/100.000 habitantes. A baixa escolaridade foi um fator relevante. A LTA foi mais prevalente em indivíduos do sexo masculino, na faixa etária de 20 a 59 anos, de cor parda e residentes em zona rural. A forma clínica mais prevalente foi a cutânea, sendo em sua maioria diagnosticada por exames laboratoriais. A taxa de letalidade da LTA foi baixa e a maioria dos casos evoluiu para a cura. Conclui-se que é necessária a mobilização constante de recursos para que os planos e ações de controle propostas pelo Ministério da Saúde tornem-se eficazes, e também que profissionais de saúde sejam capacitados para atuarem nos serviços rotineiramente.

Abstract
Italian Directives recommend the good quality of natural mineral waters but literature data assert a potential risk from microorganisms colonizing wellsprings and mineral water bottling plants. We evaluated the presence of microorganisms in spring waters (SW) and bottled mineral waters (BMW) samples. Routine microbiological indicators, additional microorganisms like Legionella spp., Nontuberculous mycobacteria (NTM) and amoebae (FLA) were assessed in 24 SW and 10 BMW samples performing cultural and molecular methods. In 33 out of 34 samples, no cultivable bacteria ≥10 CFU/L was found. Cultivable FLA were detected in 50% of water samples. qPCR showed the presence of Legionella qPCR units in 24% of samples (from 1.1 × 102 to 5.8 × 102 qPCR units/L) and NTM qPCR units in 18% of samples (from 1 × 102 to 1 × 105 qPCR units/L). Vermamoeba vermiformis and Acanthamoeba polyphaga were recovered respectively in 70% of BMW samples (counts from 1.3 × 103 to 1.2 × 105 qPCR units/L) and 42% of SW samples (from 1.1 × 103 to 1.3 × 104 qPCR units/L). Vahlkampfia spp. was detected in 42% of SW and 70% of BMW samples (from 1.2 × 103 to 1.2 × 105 qPCR units/L). Considering the presence of FLA, we underline the importance of a wider microbiological risk assessment in natural mineral waters despite the absence of cultivable bacteria.

Published: April 2018

Abstract
On-site odor measurements and mathematical modeling are useful for identifying the odor impact at the source and receptors located in areas adjacent to wastewater treatment plants (WWTPs). Impact of open area sources can be significant and may influence air quality both at the WWTP area and downwind in the surrounding areas. In this work, results of the odor measurements carried out in the spring and summer season for sources within three different mechanical-biological WWTPs in Poland are presented. The odor impact assessment was completed using a Polish reference model. The odor emission scenarios considering the contribution of major odor sources within WWTPs and the seasonal variation were determined. Obtained results showed significant differences between spring and summer seasons. The highest and the lowest measured odor concentrations at the WWTP property line were 75 ouE/m3 (July) and 6.4 ouE/m3 (March), respectively.

Published: April 2018

Abstract
This study compares and contrasts the glyphosate removal efficiency of alum sludge (waterworks residue) and Irish peat in aqueous solution. Organic phosphonate of glyphosate aqueous solution was removed in pot tests separately filled with peat and alum sludge, while effluent samples were taken from each pot to analyse the concentration of phosphorus (P) and COD (chemical oxygen demand); physical and chemical analysis for both media before and after use was carried out subsequently. The results show that the P removal capacity of alum sludge was significant (&gt;99%), while the removal capacity of peat was considerably less than 10% after 10 weeks. Both materials significantly reduced the levels of COD, but it was noted that peat had a marginally greater initial P removal capacity (68 ± 22%) and did perform better than alum sludge (57 ± 12%). Moreover, pre-treatment is a crucial step to harness the full potential of peat. Overall, this study provides a scientific clue for sorbents selection when considering alum sludge and peat to maximize their value in practice.

ABSTRACT. The aim of this study was to analyze the soil geoelectric behavior, through geophysical surveys, in the surrounding region to Bonita Lake, a natural reservoir located in the Ecological Station águas Emendadas (ESECAE), 50 kilometers from Brasília (Brazil). Sixteen vertical electrical sounding (VES) were performed with Schlumberger array. The geoelectrical model, obtained by inversion of the field data and statistical analysis of the inverted data, indicated structure with superficial dry soil above partially saturated layer, and finally a soil or rock with low permeability, related to the aquifer formation with varying thickness, about ten meters below the lake and up to twenty meters deep in the surrounding area. The VES showed that the aquifer has great lateral extension to the north, east and west of the lake; providing water to the same, while in the south, the aquifer is possibly limited by quartzites of the Canastra Group. This restriction can result in the absence of aquifer recharge in the southern portion, and coincides with the region where the lake drains into the source of Mestre D’Armas stream. This information is important because it can be used in the delineation of the hydrogeological basin and the Bonita Lake protection perimeter. Keywords: Ecological Station of águas Emendadas, aquifer, geophysics, vertical electrical soundings. RESUMO. O objetivo deste estudo foi analisar o comportamento geoelétrico do solo, por meio de levantamentos geofísicos, na região circundante à Lagoa Bonita, um reservatório natural localizado na Estação Ecológica de águas Emendadas (ESECAE), a 50 quilômetros de Brasília (Brasil). Dezesseis sondagens elétricas verticais (SEV) foram realizadas com arranjo de Schlumberger. Os modelos geoelétricos, obtidos pela inversão dos dados de campo e análise estatística dos dados invertidos, indicaram uma estrutura com solo superficial seco sobreposto a uma camada parcialmente saturada e, por fim, um solo ou rocha com baixa permeabilidade, referente a formação aquífera, com espessura variável, cerca de dez metros abaixo da lagoa e até vinte metros de profundidade na área circundante. As SEV demonstraram que o aquífero possui grande extensão lateral para norte, leste e oeste da lagoa; fornecendo água para a mesma, enquanto que, na direção sul, o aquífero é possivelmente limitado por quartzitos do Grupo Canastra. Esta restrição pode resultar na ausência de recarga do aquífero na porção sul, e coincide com a região onde a lagoa drena para a nascente do ribeirão Mestre D’Armas. Esta informação é importante, pois pode ser utilizada no processo de delimitação da bacia hidrogeológica e delimitação do perímetro de proteção da lagoa Bonita. Palavras-chave: Estação Ecológica de águas Emendadas, aquífero, geofísica, sondagem elétrica vertical.

Since the government of Indonesia has launched the Decree of Republic Indonesia Number 20 year 2003 regarding The National Education System and The Government Regulation year 2005 in relation to National Education Standard, the government was implemented the schoolâ€™s piloting on international standard. However, in itsâ€™ curriculum development was not expected with the intended regulation. The expectation of the school curriculum is supposed to be the curriculum used by the country under the OECD (Organization for Economic Co-operation and Development). The intended curriculum in this matter particularly is the curriculum used by the educational concern which is reference to the Graduate Competence Standard (SKL) and the Content Standard (SI) that all enrich to with reference to the OECD member country or the curriculum used by developed countries. To enrich the curriculum can be done by two ways. First is adaptation. It means to adapt certain part of the National Education Standard with reference to the OECD member countries. Second is adoption. It means to add some certain parts of curriculum of the OECD member countries or others which is not included in the national content standard. Therefore, the graduates have qualification from both the national education system as well as from the OECD member countries.Â ABSTRAKSejak berlakunya UU Nomor 20 Tahun 2003 tentang Sistem Pendidikan Nasional dan PP Nomor 19 Tahun 2005 tentang Standar Nasional Pendidikan, Pemerintah telah menyelenggarakan rintisan sekolah bertaraf internasional (RSBI). Namun, dalam pengembangan kurikulumnya belum seperti yang diharapkan. Kurikulum yang digunakan seharusnya kurikulum yang disusun dan dilaksanakan oleh masing-masing satuan pendidikan mengacu pada Standar Kompetensi Lulusa (SKL) dan Standar Isi (SI) yang â€œdiperkayaâ€ dengan mangacu pada kurikulum salah satu negara anggota Organization for Economic Co-operation and Development (OECD) dan/atau negara maju lainnya yang mempunyai keunggulan tertentu di bidang pendidikan. â€œDiperkayaâ€ dapat dilaksanakan melalui dua cara: 1) Adaptasi, yaitu penyesuaian unsur unsurÂ tertentu yangsudah ada dalam SI/SKL dengan mengacu pada kurikulum salah satu negara anggotaÂ OECD dan/atau negara maju lainnya, dan 2) Adopsi, yaitu penambahan unsur-unsur tertentu yang belum ada dalam SI/SKL dengan mengacu pada kurikulum salah satu negara anggota OECD dan/atau negara maju lainnya. Dengan demikian, lulusannya dapat memiliki sertifikat (ijazah) dari Indonesia dan dari alah satu negara anggota OECD dan/atau negara maju lainnya.Â

This article is an analysis of the criticisms of the practice of education in Indonesia. This criticism is based on the storyline presented in the â€œLaskar Pelangiâ€ (LP) movie. This article aims to analyze the essence of the LP movie seen through the sociologycal perspective. The essence of the film is more focused on social criticism conveyed through this film. Theoretically, education has two conflicting functions. According to the functional perspective, the positive function of education are transmit values across generations. Instead, the conflict perspective to explain that education actually leads to social inequality. More symbolic interactionism perspective see how the actors involved in the education process related to each other. Some of the criticism is delivered in between the formal education process that leaves the essence of education itself, the exclusivity of school functions, the formalization of education, inequality of access to education for lower-class society that cause social inequality, educational autonomy have not fully autonomous and the dichotomy of your favorite school and favorite. These conditions that characterize the dynamics of ational education so far has led to social inequality.Â ABSTRAKArtikel ini merupakan analisis mengenai kritik terhadap praktik pendidikan di Indonesia. Kritik ini lebih didasarkan pada alur cerita yang disampaikan dalam film â€œLaskar Pelangiâ€ (LP). Artikel ini bertujuan untuk menganalisis esensi film LP yang dilihat melalui kaca mata sosiologi. Esensi film lebih difokuskan pada kritik sosial yang disampaikan melalui film ini. Secara teoritis, pendidikan memiliki dua fungsi yang saling bertentangan. Menurut perspektif fungsional, pendidikan berfungsi positif untuk mentransmisikan nilai-nilai antargenerasi. Sebaliknya, perspektif konflik menjelaskan bahwa pendidikan justru menyebabkan terjadinya ketimpangan sosial. Perspektif interaksionisme simbolik lebih melihat pada bagaimana aktor-aktor yang terlibat dalam proses pendidikan saling berhubungan. Beberapa kritik yang disampaikan di antaranya adalah mengenai proses pendidikan formal yang meninggalkan hakikat pendidikan itu sendiri, eksklusifitas fungsi sekolah, formalisasi pendidikan, ketidakmerataan akses pendidikan bagi masyarakat kelas bawah yang menyebabkan ketidaksetaraan sosial, otonomi pendidikan yang sepenuhnya belum otonom serta dikotomi sekolah favorit dan tidak favorit. Kondisi-kondisi inilah yang mewarnai dinamika pendidikan nasional sampai saat ini yang telah menyebabkan terjadinya ketidaksetaraan sosial.Â

The purpose of the article is to present the applicability of QFD method to the design of recreation services. QFD method is an excellent tool for the design and preparation of service in the way that avoids inconsistency during its delivery, and it takes the customer's requirements into account. Using this method allows to obtain the customer's opinion before the service is provided, thereby allowing service providers to protect themselves from possible dissatisfaction and, consequently, claims and loss of the customer. The analysis of the subject literature and description of the case study were used as a research method. So far, QFD method has been used mainly in the design of products and production processes. The possibilities of its application in services are very wide, and its usefulness in terms of potential benefits is very high. The first section of the article presents the specificity of recreation services, its characteristics and determinants of proper preparation, as well as the basic forms of providing these services. The second section concerns the characteristics and a detailed description of QFD method. The third one presents a practical example of using this method in the design of the selected recreation service.
Prognozowanie dynamiki gospodarczej Niemiec z pomocą modeli warunkowych (1992-2014)
Authors: Łuczyński Wiesław Edward 
Published: April 2018

A great diversity characterizes economic dynamics of Germany over a long period of time. This refers to many time series: in some periods, they show large volatility which then moves into stability and stagnation phase, generating specific difficulties in a long-term forecasting of economic dynamics. The aim of the research is the attempt to determine the prognostic efficiency of conditional modelling and to answer the question whether or not conditional errors are significantly smaller than the unconditional ones in long-term forecasting.The research showed that conditional errors (root mean square errors RMSE) of an ex- post forecast did not differ significantly from the unconditional RMSE. The decreasing RMSE of the ex-post forecast for Germany’s individual economic processes (with the assumption that an intercept occurs in the ARMA procedure) was correlated more strongly with the procedure of filtering economic time series than with the application of the conditional maximum likelihood method (ML) and robust procedures. The relationship between a decreasing RMSE of the ex-post forecast and the application of conditional ML methods occurs in ARMAX forecasts (with exogenous processes) for data filtered with Hodrick - Prescott (HP) filter. It is worth pointing out that a relatively high prognostic efficiency of the robust (resistant) estimation of quantile regression occurs for the economic series linearized with the help of the TRAMO/SEATS method.

DEMATEL is an efficient tool for the identification of cause-effect relations which link the objects considered. A dynamical development of its popularity in recent years has resulted in numerous efforts to eliminate its weaknesses and to extend its application potential. For example, one of the attempts involved transforming it into a universal decision-making support tool aimed at weighting and ranking objects seamlessly. A critical review of the existing weighting and ranking extensions in DEMATEL is, therefore, presented in the paper. Conclusions about the usefulness of the available extensions have been drawn based on the results of an exemplary analysis.

Authors: Zepeda Quintana David Slim , Velazquez Contreras Luis Eduardo 
Published: April 2018

Over the last decades, Sustainable Development (SD) has been a focal point in a large number of international political and academic settings. In order to encourage this change, education needs to evolve into an education committed with the sustainability, particularly higher education (Lambrechts, et al. 2013). This paper aims to describe experiences and remarks regarding The International Workshop on Campus Sustainability held on Wroclaw, Poland on May 2016. The objective of this workshop was identify fragilities and weaknesses in higher education institutions, which can lead to irreversible loses. As a follow-up, in June of 2016, a replication workshop was held in the city of Hermosillo, Sonora, Mexico with the objective of exploring new outcomes and gain more knowledge in identifying fragilities and weaknesses in higher education institutions. As a result, it is intended to create a new set of indicators of fragility that contribute in our path towards SD.
Planning a market exit strategy for manufacturers of consumer goods when entering foreign markets
Authors: Döring Maik 
Published: April 2018

Aim: The internal market for manufacturers of consumer products companies is often too small in order to grant long-term success. Therefore, companies expand and enter foreign markets. This paper presents a planning process for market penetration for the selected foreign market, which will show the possibility of a withdrawal and shows also whether an exit scenario is planned by manufacturers of consumer products and when companies tend to think about a market exit.Design / Research methods: First, the literature was studied. Based on this, hypothesis were prepared. This was followed by a telephone survey of decision-makers from German manufacturers of the consumer products companies. Conclusions / findings: A planning process for market penetration was developed, which shows next to the market entry also the market exit. Additional this paper shows that manufacturers of consumer products companies can be better prepared for a market exit than companies without an exit strategy, in particular, if the manufacturer sets out relevant economic parameters for the foreign market which determine whether to remain in the market or leave.Originality / value of the article: When analysing literature on planning processes for market entry, it becomes clear that an exit strategy is not planned. This may indicate that the authors did not consider a market exit and/or anticipate this as a worst case in their market entry assumption.Implications of the research: The last market entry of the surveyed companies usually occurred recently. For market exit results to be determined, a further consultation of the companies examined should be undertaken over a longer period of time.
