WstępBorelioza z Lyme (Lyme borreliosis – LB) jest najczęstszą chorobą odkleszczową u ludzi. Celem pracy było przeprowadzenie wstępnej analizy występowania zaburzeń słuchu u chorych na LB.Materiał i metodyTesty audiometryczne objęły 66 chorych z rozpoznaną LB, w wieku od 18 do 45 lat. Wszyscy badani (kobiety i mężczyźni) zostali podzieleni na dwie główne grupy: 1 – wczesnej, rozsianej LB i 2 – późnej LB; wśród nich zostały wyodrębnione podgrupy pacjentów z rozpoznaniem neuroboreliozy (Lyme neuroborreliosis – LNB). Diagnostykę narządu słuchu przeprowadzono na podstawie badań audiometrii tonalnej, audiometrii tonalnej rozszerzonej (o wysokiej częstotliwości do 18 kHz), audiometrii impedancyjnej i audiometrii mowy.WynikiNieprawidłowe wyniki testów audiometrycznych stwierdzono u 66,7% badanych, a analiza statystyczna wskazała na istotny związek z zakażeniem Borrelia burgdorferi (p = 0,017). Większość stanowiły osoby z późną LB, zarówno bez, jak i z LNB.WnioskiZaburzenia słuchu różnego stopnia występują u ponad połowy chorych na LB, zwłaszcza w późnych stadiach procesu chorobowego. Uzyskane wyniki wskazują na konieczność prowadzenia dalszych wszechstronnych badań uwzględniających uszkodzenie narządu słuchu i równowagi w przebiegu LB, obejmujących większe grupy chorych.

El objetivo del trabajo fue comparar el efecto de tres aditivos (dos probióticos y un antibiótico) en el comportamiento productivo y la salud de cerdos en el período post- destete. Para esto se utilizaron 120 cerdos castrados, del cruce Landrace x Large White con padre Blanco Belga x Pietrain, de 28 d de edad y 6,87 kg, distribuidos en tres grupos experimentales según diseño completamente aleatorizado con cuatro repeticiones cada uno. Los tratamientos (T) evaluados fueron: 1 kg de virginiamicina al 2% por tonelada de alimento (T1), 1 kg de probiótico con Saccharomyces cerevisiae, Bacillus subtilis y enzimas digestivas por tonelada de alimento (T2) y 15 mL de preparado ecuatoriano con bacterias lácticas, levaduras y enzimas por kg de peso vivo (PV) de los animales (T3). En este último grupo fue donde se obtuvo el mayor peso vivo final (25,85 kg, P<0.0001) y la mejor ganancia de peso total (18,97 kg, P<0.0001) y diaria (451,75 g/d, P<0.0001). También, para el mismo grupo se encontraron las conversiones de materia seca, proteína bruta y energía metabolizable más eficientes (1,52 kg/kg de PV; 381,57 g/kg de PV y 22,99 MJ/kg de PV, respectivamente). El porcentaje de animales con diarreas difirió (P<0,0001) entre el grupo que recibió la virginiamicina (50,61%) y los aditivos microbianos (27,98% y 21,39%), sin diferencias entre estos últimos. Se concluye que los aditivos microbianos mejoran el comportamiento productivo y sanitario de cerdos en post-destete con respecto a la virginiamicina, y este efecto fue mayor con el preparado microbiano ecuatoriano.

Elaboración de un producto tipo ‘pasta alimenticia’ a partir de residuos de plátano hartón prefreído
Authors: Chaparro-Acuña Sandra Patricia 
Published: October 2018

El propósito de este estudio fue aprovechar los recortes de plátano hartón prefreído, o subproducto de patacón (SPP), que las empresas producen en la elaboración de patacones y que representan, aproximadamente, un 30 % de pérdidas mensuales. Dada la alta perecibilidad de estos residuos, se formuló un producto de buena aceptabilidad, con una vida útil más larga y que facilitara el manejo del subproducto. Se utilizaron tres harinas de trigo de diferente marca comercial, sémola de trigo y SPP en diferentes proporciones para establecer la mínima inclusión de harina en la formulación del producto tipo “pasta”. Las pruebas de absorción y pérdida de agua determinaron que la mejor mezcla fue la que contenía 65 % de residuos de plátano hartón prefreído y 35 % de sémola de trigo. Las pruebas sensoriales con consumidores ayudaron a la selección de esta formulación. Los análisis de textura realizados mostraron mayor fracturabilidad y menor firmeza del producto tipo “pasta” con relación a una pasta patrón, pero durante la cocción se mantuvo estable y presentó buena consistencia.

La génesis de los suelos comprende el estudio de los factores y procesos de formación de estos; es la síntesis y la explicación del porqué de los suelos y de sus características y distribución. El conocimiento de la génesis, evolución, mineralogía y estado actual de los suelos se convierte en una herramienta fundamental para el ordenamiento territorial y productivo y la conservación de zonas estratégicas. El Valle del Sibundoy, ubicado al noroccidente del departamento de Putumayo, cuenta con una extensión aproximada de 9100 ha (IGAC, 2014); en esta superficie se realizó un levantamiento de suelos a escala semidetallada, y con este se determinaron los factores que rigen su origen y se infirieron los procesos que se han dado y que han dejado marcas en el perfil del suelo. Se diseñó un sistema de muestreo en red rígida, donde se distribuyeron 402 cajuelas, cada 25 ha, aproximadamente; posteriormente, se caracterizaron 71 perfiles modales. Con los datos obtenidos en campo y los resultados del laboratorio se concluyó que los factores que rigen la geogénesis en la zona de estudio son, en primera instancia, el relieve; en segunda, el material parental, y en tercera, el clima y la acción de los organismos a través del tiempo; además, se identificaron tres tendencias específicas de evolución: andolización, paludización y gleyzación; cada uno de estos procesos específicos se corroboró con análisis micromorfológicos.
Seroprevalence of Mycobacterium avium ssp. paratuberculosis in small ruminants in a flock in Antioquia, Colombia
Authors: Hernández-Agudelo José Miguel , García-Tamayo Yadi Marcela , Fernández-Silva Jorge Arturo 
Published: October 2018

Paratuberculosis is a chronic infectious disease caused by Mycobacterium avium ssp. paratuberculosis (MAP). This study aimed at determining the presence of antibodies against MAP, and the association between the serological status of MAP and individual factors in goats and sheep in a flock in Antioquia, Colombia. We studied fifty-three goats and 6 sheep over two years old, and took blood samples to obtain serum and information on individual factors. The presence of antibodies against MAP was determined by ELISA, whereas the information was descriptively analyzed. ELISA did not detect any positive or suspect animal among the 59 tested animals, so an association between serological status to MAP and individual factors could not be established. This is the first and the fourth study reporting the search for antibodies against MAP in a goat and in a sheep population in Colombia, respectively. Several factors may explain the serological status of the sampled animals. It is necessary to continue with similar studies in other flocks of the region and the country to determine the current MAP infection status in small ruminants in Colombia.

Se realizó un experimento con la finalidad de estudiar un complejo de enzimas fibrolíticas exógenas (Fibrozyme®) sobre los parámetros de degradabilidad ruminal in situ y la cinética de degradación de la materia seca (MS) de la paja de garbanzo (Cicer arietinum). Se utilizaron dos toros suizos (700 kg PV) con cánula ruminal, en un diseño de bloques al azar, donde cada animal constituyó un bloque. Se evaluaron tres niveles de enzima (0, 1 y 2 g Fibrozyme® kg forraje−1 MS). Se colocaron bolsas nailon a cinco tiempos de incubación (6, 12, 24, 48 y 72 h). Los resultados demuestran que la inclusión de 2 g Fibrozyme® kg-1 MS mejora la digestibilidad in situ de la materia seca en paja de garbanzo (P<0.05) para todas las horas incubadas, así como los parámetros de la cinética de degradación. Se concluye que el Fibrozyme® evaluado en una dosis de 2 g kg-1 forraje MS mejoró la cinética de degradación y la degradabilidad ruminal in situ de la MS del esquilmo agrícola evaluado.

Application of Integrated Reservoir to Surface Network Coupling of Giant Oil Field, Kazakhstan
Authors: Stepanchuk Artem , Amangaliyev Bagdad 
Published: October 2018

Abstract
Pressure losses in the surface network can have a critical impact on well productivity. Therefore, for field development planning, it is highly advantageous for the simulation model to include the surface facilities as well as the reservoir. The objective of this study is to outline the advantages of modeling reservoir-to-surface coupling over conventional standalone simulation.
This paper presents a case study of creating an integrated model of a giant oil field with a compositional surface gathering system. The reservoir model is controlled by complex field management logic including gas balance. The reservoir wells are balanced with the surface network by setting inflow performance relationships (IPRs) as the boundary conditions. The network is then solved and returns operating point pressure as a varying tubinghead pressure (THP) limit for the reservoir well. After the minimum THPs have been established, the guide rate balancing allocates production by respecting the THP limits at which wells can flow.
The results show that an integrated reservoir-to-surface coupling gives significantly different but more realistic production allocation profiles at the group and well levels than a separate standalone simulation model. The oil production plateau rate drops prematurely as surface-network-constrained guide rate balancing results in different production allocation between producing wells. In fact, updated allocation results in an increase in gas-oil ratio for some of the groups and consequently leads to early gas breakthrough for some of the wells. Increase of stability in results and speed were achieved by selecting the appropriate reservoir-to-surface-network balancing frequency and leveraging the power of multicore hardware.
The sequence of network and guide rate balancing can over-constrain some of the high-capacity groups by a higher THP limit. To avoid this, a nested approach is presented that includes an additional network balancing step that is solved by IPRs based on guide rate balancing, which allows reducing the THP limit and prolongs the plateau rate. Based on this field example, integrated modeling has proved to bring value by providing more accurate profiles and debottlenecking of surface facilities.

Abstract
The paper considers new approaches to further development of mature gas-condensate fields, which are aimed at the maximum recovery of in-place reserves using the systems of horizontal wells. The gas-hydrodynamic simulations on the sector model of a depleted field were performed.
Analysis of geological features of the fields of Uzbekistan is crucial to the planning of horizontal wells. As an example of how geological features are taken into account for effective further development of the fields, the reservoirs of Amudarya oil-and-gas basin are described.
The questions of geosteering, well targeting along the formation and optimum completion of horizontal and multilateral wells, including with the use of inflow control devices, are addressed.
Studies found the appropriateness of the operation of horizontal wells in comparison with vertical wells, which have several technological and economic advantages, such as the cost of such wells, simplified system of surface facilities, production rate as fraction of in-place gas reserves.

Abstract
Logging wells drilled in coalbed methane reservoirs (CBM) is a common practice in the industry. As a rule of thumb, the logging suite comprised of standard methods is run to identify coal layers for subsequent degasification. However, given the increased popularity of the commercial methane production from CBM reservoirs, the petrophysical data from standard methods is not sufficient to evaluate the productivity of deposits and to assess the effectiveness of such projects.
The permeability of the coal matrix is usually non-existent. The natural fractures are key controlling factor for gas migration and the performance of a CBM reservoirs depends largely on this parameter. In this study formation microimager was used to identify fractured intervals and based on these results the most promising intervals were selected for further testing.
The well testing of low permeability formations can be extremely difficult due to the long build-up times to achieve different flow regimes. This step can be optimized by deploying wireline formation tester to estimate the permeability of the coal layers in open hole.
Innovative extended spacing dual packer configuration of the wireline formation tester was deployed to selectively test coal layers ranging from 1 to 9 m deposited at shallow depths of 200-900 m. Fragile nature of the coal seams often resulted in washouts, which presented some challenges while inflating the packers to isolate the interval. Several cycles of fluid pumping were performed followed by pressure build-up periods until the radial flow regime was observed. Data processing and monitoring was carried out in real-time allowing to obtain high quality data and to optimize the operations.
Data acquired by formation microimager was used to perform facial analysis to determine depositional environment and to further aid in mapping the coal layers and for future well placement considerations. The knowledge about the depositional environment allows to predict the regions where coal layers are formed confined by the flooding areas.
The geological setting of the coal basin is made up of many coal layers of varying thickness deposited at depths of tens to hundreds of meters. The application of an advanced logging suite comprising of formation microimager and wireline formation tester allowed to selectively test the most promising coal layers. All the measurements were carried out in open hole at a drilling stage.

Published: October 2018

Abstract
This paper describes workflow and results of an imaging project carried out on a seismic survey on the Karachaganak field, located on-shore Kazakhstan. The aim of the study is to gain a deep understanding of the reservoir architecture and reduce the uncertainties of the model. The business driver is to support the reservoir modeling for the next field development phase.
Karachaganak is a mature oil and gas field, within the Pricaspian basin. The reservoir is an isolated heterogeneous carbonate bank, Permo-Carboniferous in age, ranging from four thousand to six thousand meters of depth. An evaporite layer serves as seal. The overburden is a clastic basin surrounded by four huge allochthonous salt diapirs.
Given the high complexity of the area under investigation Reverse Time Migration was the most suitable algorithm for handling sharp velocity contrasts and to image sub-salt targets with a high accuracy and definition. A detailed interpretation of the reservoir and overburden horizons guided a geological based seismic velocity model building. Moreover, an innovative tomographic approach was able to both constrain seismic anisotropy and honor well markers simultaneously.
The involvement of structural geologists is part of a regular procedure when embedding salt tectonics into the geophysical model is crucial. Indeed, the interpretation of the complex salt geometry was of paramount importance for the success of the project. Furthermore, leveraging on the available computational capacity, testing multiple scenarios in very short time allowed supporting the QA and QC processes, reducing the uncertainties in the most challenging areas.
The final high-resolution image is consistent with well data, logs and cores, matching more than one thousand markers. A clear image of the inner reservoir reveals seismic stratigraphic features previously hidden. The combination of cutting-edge imaging technology, running on the best in class industrial supercomputer in the world, the expertise in geoscience and the commitment of a multidisciplinary team were the key factor to achieve these results.

Abstract
Central Asia has become one of the energy hubs in the world with latest significant discoveries including but not limited to Kashagan, Tengiz, Karachaganak, Azeri-Chirag-Guneshli fields. Geographical and political dynamics of the Central Asian countries help the countries to stand out as a significant stable and sustainable source of energy in the region with great resources of supply and low domestic demand. This study outlines economic and technical analysis of oil and gas resources of central Asia under demand and supply dynamics of world hydrocarbon production. A comprehensive literature review has been carried out to investigate the basins and major oil and gas fields of the region, their development from the beginning, the technologies utilized, types of recovery processes, supply capabilities and potential of future supply are addressed. Real field applications are illustrated with applications in different parts of the region with challenges, advantages and drawbacks discussed and summarized in comparison to other major energy hubs of the world and their major oil and gas fields and basins. Central Asia is a relatively young and dynamic region with growth potential of harnessing the great and relatively new resources. Due to the political and geopolitical dynamics of the region, Central Asia serves as a strong and stable provider of energy obtained from fossil fuels. Low domestic demand in the region makes it more attractive in terms of the amount of export potential. There is no recent up-to-date study that investigates and outlines not only the technical characteristics of fields, reservoirs and basins in the region but also the demand/supply dynamics of the resources in the regions as they compare to the other major energy hubs in the world. This study comparatively outlines the key elements of successful applications in the region along with the lessons learned from challenges as well as the current and near-future potential of Central Asia as an energy hub in the world.
