The Principal of Risk and Profit Sharing in Islamic Banking
Authors: Supriatiningsih Eka
Published: November 2018

The role of banking that is very strategic in achieving Indonesia's economic development goals recently, requires a careful study of banking concepts that have been operationalized, both conceptually and their applications, so as to create a strong banking system in the era of globalization in the future. The existence of Islamic banks in Indonesia has not been fully accepted, there are still some people who equate with conventional banks. Based on the background of the problem above, which is the identification of the problem in this paper, namely: 1) What is the application of the principle of sharing the results and risks in fundraising activities in Islamic banking? 2) What are the operational constraints faced in implementing profit sharing and risk principles in Islamic Banking?. Based on the discussion above, conclusions can be drawn, as follows: 1) The implementation of fundraising using the profit sharing principle in Islamic Banking is carried out using the principles of Wadiah and Mudharabah. The Wadiah principle uses the Wadiah Current Account using products such as: Singapore BSM Dollar Current Account, BSM Current Account, BSM Currency Current Account, BSM Ouro Current Account, Bank Muamalat Wadiah Deposit Account in Rupiah and Foreign Currency, personal and corporate, and Wadiah Savings Account using products like: Junior Community Savings which is a special savings for students, Simpatik Savings, BSM Dollar Savings. While the mudharabah principle uses the Tabungan Mudharabah contract using products such as: Mudharabah Savings Accounts are Hajj Savings, Investa Scholar Savings, Qurban Savings and Savings Cards and time deposits for mudharabah use products such as: Bank Syariah Mandiri Savings, BSM Foreign Currency Deposits and Mudharabah deposits. In calculating profit sharing only in Mudharabah principles, the wadiah principle is only a bonus given to the bank's willingness. The pattern of calculation for results is to use the principle of profit sharing, which means that the results are calculated from the total income of the fund management and the amount of profit sharing depends on the initial agreement, 2) There are a number of operational constraints faced by Sharia Banking in financing Financing Results such as limited human resources, Islamic Banking management, limited Office Networks, and still weak government regulations on Islamic Banking.
REVIEW OF SOME ECOLOGICAL ASPECTS OF STERLET (ACIPENSER RUTHENUS LINNAEUS, 1758)
Authors: Chemagin Andrey Aleksandrovich
Published: November 2018

The article presents the review of scientific works on ecology and biology of sterlet aspects of its distribution, spawning, migration, feeding and accumulation of heavy metals in organs and tissues. It has been stated that in natural populations there are two morphs - with a sharp (long) and blunt (short) rostrum. It has been assumed that they are characterized by the separation of spawning period into time intervals. In artificial aquaculture sterlet individuals show a decrease in morphometric traits, which may result from the identical farming conditions or the reduction of genetic diversity. The background color of the tanks used for cultivation can affect the linear-weight characteristics of fish: in light colored tanks there are fish of smaller sizes, in dark colored ones - fish of larger sizes. It has been found that the color of the species body similar to the bottom substrate acts as s a highly effective protection against predators in turbid waters. The study of sterlet population of in the Ob’-Irtysh and Yenisei basins showed that the former population has a higher genetic diversity index. Migration length of sterlet is insignificant: up to 250 km. It spawns in the spring-summer period, in winter period it concentrates in the wintering holes. The leading role in sterlet feeding belongs to the representatives of benthos and zooperiphyton, which are characteristic of lithophilic, lythoreophilic and psammoreophilic biocenoses. Maximum concentrations of heavy metals have been registered in the liver and gills, minimal in the muscles. The largest accumulation of elements is noted for Fe, Al and Zn, the minimum for Cd and Co.

In the context of globalization, the importance of improvement of the economy competitiveness is increasing. In order to develop the Russian industries, federal authorities have taken steps to implement the program approach. At the same time, among a wide variety of industries, the shipbuilding industry is recognized as one of the priority. The article identifies the trends in development of shipbuilding industry in Russia and abroad - investment activity. There has been considered the state, problems and priority directions of development of shipbuilding in the context of the investment policy implemented within the framework of the existing program of the Russian Federation for the development of shipbuilding. The direct and indirect influence of investments on the branches of the economy is analyzed, examples of attracting investments in the context of free placement of investments or limiting their presence in a country are given. The results of the state policy in the field of shipbuilding have been considered.The special features of shipbuilding production, the instability of the external environment have determined the specifics of investment in the industry. The analysis of investment mechanisms into the shipbuilding industry has been made on the example of tools of the state support at the level of the entities of the Russian Federation. The characteristics of the form of state support for special economic zone on the example of the “Lotos” economic zone (the Astrakhan region) have been considered. The economic zone in the Astrakhan region, due its geopolitical location and economic potential, will base on enterprises of shipbuilding complex; in this connection, there have been formulated conditions for characterizing efficiency of the special economic zone development. There have been shown the results of the general economic effect obtained due to investments in the region.

Published: November 2018

Theory of linguocultural types, shaped in Volgograd research school, today is successfully developing: there is a great variety of reports related to this problem. Scientific novelty of the paper lies in emphasizing ethno-linguistic type “native bilingual” and in identifying its value characteristics. Among lingvocultural types, this type takes a special place because it is characterized by linguistic uniqueness (ethnic belonging and natural bilingualism). The following official documents served as the material for research: the Universal Declaration of Linguistic Rights; the Constitution of the Russian Federation, etc.
DEVELOPMENT OF AGENT SIMULATION MODEL OF A PROCESS DESCRIBING THE HYDRAULIC DEVELOPMENT OF SOIL FOR DREDGING
Authors: Sapunov Grigory Ivanovich , Holodov Artem Yurievich
Published: November 2018

The article describes the process of hydraulic soil development when performing dredging operations in terms of a probabilistic process. To give the mathematical description of this process, the stochastic differential Langevin equation is used, which makes it possible to determine the velocity of the particle moving along the spatial axis in case of multiple collisions with other soil particles. In order to establish the adequacy of this approach with the experimental data obtained through the utility model there has been developed an agent simulation model. A population of agents containing a module of the system dynamics realizing the differential equation is integrated into the structure of the model.

Authors: Aldokhin Andrey Stepanovich , Volosnikov Gleb Igorevich
Published: November 2018

In the summer period (June-July) of 2018 on the Irtysh river (the Tobolsk region) in the control catches of sterlet there were found specimens with pronounced differences from individuals inhabiting this water area. Differences were found in the form of bone plates and linear-weight characteristics. Later, local fishermen reported on many cases of specimens having the above differences. Reports about the similar species came from the Uvat region. In order to establish the belonging of these individuals to a particular family there have been investigated meristic features which are considered diagnostic for sturgeon species, as well as for hybrids. In the result of the study there was made a conclusion about belonging of these specimens to the genus Acipenser and, most likely, to the sterlet species.
CALCULATION OF INDUCTANCE FOR A BI-DIRECTIONAL DC/DC CONVERTER IN AUTONOMOUS UNDERWATER APPARATUS
Authors: Avdeyev Boris Aleksandrovich
Published: November 2018

Submersible apparatus work at a depth inaccessible for divers and submarines. They are small devices linked with the depot ship due to their limited autonomous capacity. Application of submersible apparatus helps to enlarge the range of their operation and to decrease maintenance costs. Accumulator storage batteries with relatively low voltage are the main power source of these apparatus. DC converter operation is influenced by the inductance value. The article deals with the problems of calculating the inductance for bi-directional DC voltage converters for autonomous underwater apparatus. The scheme of the converter is presented, its operation modes are considered, equations describing the processes in the electrical circuit for different states of the IGBT-transistor are compiled. An expression describing the current oscillations in the regime of continuous current with certain assumptions is derived. It is stated that the inductance should be greater than a certain value to ensure the operation of the DC converter in the continuous current mode. Dependences of the current ripple through the inductor are plotted as a function of the inductance. Simulation of the DC converter made in the Simulink package is performed and oscillograms of the current and voltage at the output of the converter are shown, which confirm the correctness of the procedure for determining the minimum value of the inductance to ensure operation of the DC converter in the continuous current mode.

Published: November 2018

The article describes the ship shaft line which is a constructive complex linking kinematically the main propulsion engine to the thruster and designed to pass torque moments and axial loads, appearing in the operation process of the ship propulsion system. Service life of the ship shaft line depends on operational condition of stern bearings in the shaft tube, that is why they should have high resistance against actual loads and preserve operational characteristics. There is studied the influence of elastic properties of stern bearings on numerical value of eigen frequency under cross oscillations if the ship shaft line. Assessment of influence of the deadwood bearing material on the rigidity coefficient is made. The settlement scheme for studying cross fluctuations represents a beam with constant cross section that leans on one hinged immovable elastic support with a rigidity coefficient c . At the end of a beam there is a concentrated load. The elastic support and the concentrated load model the stern bearing and the propeller screw, respectively. The technique of determining the rigidity coefficient subject to mechanical and geometrical parameters of the ship shaft line and its deadwood bearings is described. The importance of the numerical value of the rigidity coefficient of different materials of plugs of deadwood bearings when calculating cross fluctuations of the ship shaft line has been estimated. The real ship shaft line is investigated.

Authors: Castro-Huertas Valentina , Forero Dimitri , Grazia Jocelia
Published: November 2018

The assassin bug tribe Metapterini belongs to the subfamily Emesinae (Hemiptera: Heteroptera: Reduviidae). Morphologically, it is characterized by the conspicuous basal process of the posteroventral series in the foreleg and the presence of wing polymorphism, with a high proportion of the genera with micropterous or apterous species. Here, the male and female ectodermal genitalic structures are documented for ten genera and twenty-three species of Metapterini, including eight species of the speciose genus Ghilianella Spinola, 1850. Descriptions and digital macrophotographs are provided for abdominal segment 8, pygophore, parameres, and phallus of the male, and for tergite 8, tergite 9, gonocoxae, gonapophyses, gonoplac, and bursa copulatrix of the female. The asymmetric male genitalia within Emesinae are discussed. From this morphological documentation sixty six phylogenetic characters are coded, presented as a data matrix and analyzed cladistically, and their potential usefulness for resolving relationships among Metapterini is discussed.
Larval morphology of Yateberosus, a New Caledonian endemic subgenus of Laccobius (Coleoptera: Hydrophilidae), with notes on ‘Berosus-like’ larvae in Hydrophiloidea
Authors: Fikáček Martin , Minoshima Yûsuke N. , Jäch Manfred A.
Published: November 2018

The morphology and head chaetotaxy of the second and third instar larvae of Laccobius (Yateberosus) sp. are described based on specimens collected in New Caledonia. The larvae agree with those of other subgenera of Laccobius Erichson, 1837 in most morphological characters including the morphology of head and mouthparts and the head chaetotaxy, which undoubtedly supports its assignment to Laccobius (Yateberosus). It differs from other Laccobius in the closed spiracular system, reduced spiracular atrium and long abdominal tracheal gills, in which they resemble the larvae of Berosus Leach, 1817. We demonstrate that the ‘Berosus-likeʼ larval morphology evolved at least four times independently in Hydrophiloidea, and briefly discuss the possible reasons for it.

Published: November 2018

The aim of the study was to evaluate the influence of crop rotations, fertilisation and weather conditions on the grain yield and yield components of winter barley. Long-term field experiment was situated in the area of continental climate. There were the crop rotations with 40%, 60% and 80% share of the cereals. Two treatments of fertilisation were applied: H1 and H2. In the first treatment (H1), nitrogen, phosphorus and potassium in mineral fertilisers + organic manure Veget® were applied. In the second treatment (H2), nitrogen, phosphorus and potassium were applied in fertilisers only. Winter barley cultivar Barcelona was grown in years 2010-2015. The number of spikes per 1 m2, proportion of grains over sieve 2.5 + 2.8 mm and grain yield of winter barley were statistically significantly influenced by fertilisation. In the variant H1 (mineral fertilisation with addition of organic manure Veget®), the statistically higher (P ≤ 0.05) grain yield was obtained (5.71 t/ha) than in the treatment with mineral fertilisation only (5.30 t/ha). In the year 2011, which was very unfavourable for winter barley development, the grain yield in the treatment with mineral fertilisation with the addition of organic manure Veget® was by 1.23 t/ha (32.1%) higher than that in treatment with mineral fertilisa tion only.

The outcomes of present research gave emphasis to global warning about pollution of chemical fertilisers and safety production.
Impact of Vermicompost as Component of Growing Medium on Phytomass Formation of Radish (Raphanus Sativus L.)
Authors: Kováčik Peter , Šalamun Peter , Smoleń Sylwester , Renčo Marek
Published: November 2018

In Slovakia more than a half of the landfill‘s waste consist of the biodegradable waste (BDW). Therefore the BDW composting can decrease significantly the production of the landfill gas as well as the financial and space requirements for landfills. However, the composts production have to be solved comprehensively, including their rational usage. In Slovakia the use of composts is ineffective if the location of their production is farther than 50 km, because of the high tranportation costs. The objective of the experiments was to determine the ratio of vermicompost in the soil growing medium in order not to decrease the yield quantity and quality of radish - the most commonly grown vegetable in the gardens in Slovakia. Five shares of vermicompost were tested in the soil substrate (0%, 10%, 20%, 25% and 50%). The results show that 50% share of vermicompost in the soil substrate, i.e. the ratio of vermicompost to soil 1:1, was not the optimal solution of the vermicompost usage. However, even this quantity of vermicompost did not have a negative impact on the weight of the aboveground and underground phytomass in comparison with the treatment without vermicompost. 50% share of vermicompost in the growing medium had the negative impact on the qualitative parameters of radish. It decreased the content of vitamin C and increased the content of nitrates in radish roots and leaves. Along with the higher share of vermicompost in the growing medium, the content of vitamin C was decreased in radish roots and leaves, and the content of nitrates in radish roots was increased. The roots of the biggest diameter, and consequently the highest yield of radish roots and leaves was formed in the treatment where the soil substrate consisted of four portions of soil and one p ortion of vermicompost (20% proportion of vermicompost).

Published: November 2018

Drought is one of the major abiotic stresses that frequently causes severe loss in crop yield worldwide. Laboratory predictors of field drought tolerance could significantly increase the effectiveness of existing plant breeding programs. In earlier field experiments, drought tolerance of 22 cultivated barley varieties has already been quantified. In order to develop laboratory markers of drought sensitivity, field drought tolerance data were correlated with parameters obtained in laboratory tests. Root and shoot length and weight were measured on control and PEG-treated (a simple laboratory drought model) seedlings. Significant correlations were found among root growth, shoot weight in laboratory stress conditions and field drought tolerance. Interestingly, a negative correlation was found between root length of the untreated seedlings and drought tolerance. Laboratory Drought Tolerance Index (DTI) was introduced as the linear combination of those laboratory parameters which were correlated with field drought tolerance. DTI showed good predictive value (r = 0.57, p < 0.05) for drought tolerance in field experiments and we suggest it for preselection of drought tolerant barley breeding lines and for the characterization of drought tolerance in general.

Authors: Novotná Jaroslava , Badalíková Barbora
Published: November 2018

The influence of different application of grape marc compost on the soil structure and the water stability of soil aggregate were studied in the course of four-year experiment. The trial was carried out in a Velké Bílovice vineyard in the Czech Republic. The altitude of the locality is about 200 m above sea level, the long-term average annual precipitation is 550 mm, the long-term average annual temperature is 9.5°C. The soil is Haplic Chernozem, loamy textured. Three variants were established: Variant 1 - control, no compost, Variant 2-30 t of compost per ha, Variant 3-60 t of compost per ha. The compost from pomace, poultry droppings, mown grass and straw was made in an EWA aerobic fermentor in an intensive and controlled process in an enclosed space and shallow ploughed (0-0.15 m) into the soil every year after harvest. The results of the experiment were statistically processed by multifactorial analysis of variance and then by Tukey’s test of simple contrasts. The highest values of structural coefficient and water stability of soil aggregate were found in the variant with the highest dosage of compost. It was found that the application of grape pomace compost to the soil had a positive effect both on the soil structure and the water stability of soil aggregates.

Published: November 2018

Plants of 13 fibre flax varieties were tested for their photosensitivity and differences of stems structure while grown in long and short daylight. It was detected that seven varieties did not change time of flowering in short 12 hours daylight in comparison with long 19 hours daylight. The extended diversity of fibre flax reactions on photoperiod changes and its relative independence of photosensitivity degree were found. Also, weak but significant correlation was found between photosensitivity coefficient and the degree of leaves number increase (r = 0.57). At the same time photo insensitive variety Belosnezhka improved leaves number up to 34%. Numbers of fibre bundles, their individual and total area on the stem cross section were not changed or reduced. Width, height, perimeter and shape of fibre bundles on a cross sections changed multidirectional. The areas of stem, its wooden part and cavity on a cross section showed no significant differences between plants grown in long and short day conditions. Evaluated flax characters were not strictly correlated with each other except those indicating the structure of fibre bundles. For breeding it is important that their relationships are not strongly influenced by the environment.

Published: November 2018

As consumer awareness increases in Poland, fish consumption is on an upward trend. While new technologies permit meeting increasing demand, they significantly increase the pressure on fish supplies. As a result, many fish stocks are over-exploited, which threatens marine ecosystems. Declining fisheries, increasing fishing operating costs, and the necessity of making longer fishing expeditions at greater distances that often end with catches of fewer or less valuable fish mean that in some fisheries sectors are currently running at the margins of profit or at a loss. At the same time, the European Union’s fisheries policy aims to create more selective and sustainable fisheries, to implement limitations through fishing quotas, and to ban the recognition of discards. The aim is to ensure that individual fish species are protected while providing the European Union with stable, secure supplies of fresh fish. The FindFish Knowledge Transfer Platform project was launched to provide solutions for challenges facing commercial fisheries. Its purpose is to provide fishers with a knowledge transfer platform and a numerical forecasting system for the marine environment of the Gulf of Gdansk. By combining in-situ research, environmental data, fish catch data, and numerical calculations, this tool will improve the accuracy of targeted fishing while reducing by-catch. The system will provide more reliable data on fish stocks and facilitate more efficient resource management.

Motivated by plane wave ultrasound image velocimetry (a.k.a. Echo PIV), we introduce a novel method to globally estimate the velocity field of a laminar and steady flow from the motion of tracer particles. Our approach exploits the fact that the equation of motion for pipe flows of constant circular cross-section is governed by a single global but unknown parameter. We connect this parameter to the Fourier spectrum of the input image sequence of the tracer particles and formulate our motion estimation problem as a spectral support estimation problem. The approach is validated on both simulated and experimental real data. It returns accurate velocity estimates after few seconds runtime and effectively copes with speckle patterns and noise.
Distributed optimal control problems for phase field systems with singular potential

Published: November 2018

In this paper we review some results obtained for a distributed con- trol problem regarding a class of phase field systems of Caginalp type with logarithmic potential. The aim of the control problem is forcing the location of the diffuse interface to be as close as possible to a pre- scribed set. However, due to some discontinuity in the cost functional, we have to regularize it and solve the related control problem for the approximation. We discuss the necessary optimality conditions.
Preconditioned Dirichlet-Dirichlet Methods for Optimal Control of Elliptic PDE
Authors: Loghin Daniel
Published: November 2018

The discretization of optimal control of elliptic partial differential equations problems yields optimality conditions in the form of large sparse linear systems with block structure. Correspondingly, when the solution method is a Dirichlet-Dirichlet non-overlapping domain decomposition method, we need to solve interface problems which inherit the block structure. It is therefore natural to consider block preconditioners acting on the interface variables for the acceleration of Krylov methods with substructuring preconditioners. In this paper we describe a generic technique which employs a preconditioner block structure based on the fractional Sobolev norms corresponding to the domains of the boundary operators arising in the matrix interface problem, some of which may include a dependence on the control regularization parameter. We illustrate our approach on standard linear elliptic control problems. We present analysis which shows that the resulting iterative method converges independently of the size of the problem. We include numerical results which indicate that performance is also independent of the control regularization parameter and exhibits only a mild dependence on the number of the subdomains.
Convective Flow of Blood in Square and Circular Cavities

In this study, the fully developed, steady, laminar ow of blood is studied in a long pipe with square and circular cross-sections subjected to a magnetic field generated by an electric wire. Temperature difference between the walls causes heat transfer within the fluid by the displacement of the magnetizable fluid particles in the cavity. The governing equations are the coupled Navier-Stokes and energy equations including magnetization terms. The axial velocity is also computed with the obtained plane velocity. The Dual Reciprocity Boundary Element Method (DRBEM) is used by taking all the terms other than Laplacian as in- homogeneity which transforms the partial differential equations into the boundary integral equations. Numerical results are given for increasing values of Magnetic (Mn) and Rayleigh (Ra) numbers. The numerical results reveal that an increase in Mn accelerates the plane velocity in the cavity but decelerates the axial velocity around the magnetic source. Pressure increases through the channel starting from the magnetic source. Isotherms show the cooling of the channel with high Mn and Ra only leaving a thin hot layer near the top heated wall. As Ra increases viscous effect is reduced leaving its place to convection in the channel. The use of DRBEM has considerably small computational expense compared to domain type methods.

Objective. This study investigated whether the metformin (Met)-induced enhanced intestinal uptake of 2-deoxy-2-[18F]fluoro-D-glucose (18F-FDG) is reduced by loperamide, a long-acting anti-diarrheal agent. Methods. Mean 18F-FDG uptake in the mouse small intestine and colon with Met exposure was compared with that in control mice. In the Met group, high-dose (1.0 mg/kg body weight) and low-dose (0.1 mg/kg body weight) loperamide were introduced, and 18F-FDG uptake in the small intestine and colon was compared with that of control mice administered high-dose loperamide. The percent injected dose of 18F-FDG per gram of tissue (%ID/g) in the extracted tissues was then determined. Results. 18F-FDG uptake increased significantly in the small intestine (0.64±0.06 vs. 1.01±0.15, p=0.040) and, especially, the colon (0.46±0.13 vs. 2.16±0.51, p<0.001) after Met exposure. Neither high-dose nor low-dose loperamide significantly reduced 18F-FDG uptake in the small intestine (0.82±0.31 vs. 0.84±0.22, p=0.93 and 0.78±0.25 vs. 0.70±0.15, p=0.13, respectively) or colon (2.13±0.41 vs. 1.67±0.55, p=0.063 and 1.77±0.39 vs. 1.80±0.25, p=0.56, respectively). The colonic %ID/g was significantly higher in Met groups irrespective of loperamide introduction than in control group, whereas the significant difference in the small intestine was observed only between Met and control groups. Conclusion. Metformin increased 18F-FDG uptake in intestines especially in colon. Loperamide administration partially, but not sufficiently, suppresses the Met-induced increased colonic uptake of 18F-FDG.

La disrupción auriculoventricular después de un cambio de la válvula mitral es una complicación rara, sin embargo presenta altos índices de mortalidad. Este es el primer reporte de un caso de ruptura ventricular luego de una plastia mitral en una paciente femenina de 69 años llevada a plastia mitral y tricuspídea. Después de terminar la perfusión cardiopulmonar, se observó ruptura ventricular localizada en el surco auriculoventricular, el desgarro fue reparado externamente con un parche de pericardio y adhesivo quirúrgico biológico. La paciente se recuperó y fue dada de alta sin complicaciones. Se discute acerca de la etiología y el reparo quirúrgico de esta complicación.

Published: November 2018

La inserción de sonda nasogástrica es un procedimiento que consiste en introducir una sonda de polivinilo a través de los orificios nasales, avanzarla por esófago hasta ubicarla en el estómago. En pacientes bajo anestesia general con intubación orotraqueal, la inserción presenta una tasa de fracaso hasta del 50% según la técnica en el primer intento. Situación que se convierte en un reto hasta para los anestesiólogos experimentados. Objetivo: Evaluar la tasa de éxito y complicaciones en la inserción de una sonda nasogástrica utilizando una guía esofágica comparada con la técnica digital a ciegas. Materiales y métodos: Estudio experimental tipo ensayo clínico controlado de dos grupos de comparación, uno experimental de 19 pacientes (grupo A) en el que se utilizó la guía esofágica para la inserción de la sonda nasogástrica, y el otro de control de 21 pacientes (grupo B) con la técnica digital a ciegas, en un periodo comprendido entre los meses de julio y diciembre del 2012. Resultados: No hubo diferencias significativas entre ambos grupos (p>0,5) en edad, peso y estatura. El tiempo utilizado para inserción de sonda fue significativamente menor en el grupo A con una media en segundos de 70,89 segundos. El número de intentos, en el grupo A fue mucho menor que en el grupo B en un 89.5% y 57,1% respectivamente para el 1er y 2do intento, mientras que en el 2do y 3er intento fue de 10.5% y 42,9%; la incidencia de enrollamiento en el grupo A fue significativamente menor que en el grupo B con 21.1% y 71,4% respectivamente. No se presentaron complicaciones en el grupo A con la inserción de la sonda frente a 3 casos en el grupo B, sin presentarse complicaciones severas en ninguno de los dos grupos. Conclusiones: El uso de una guía para el paso de la sonda nasogástrica demostró ser un procedimiento practico y efectivo que permite un procedimiento en menor tiempo cuando se emplea en paciente bajo anestesia general con entubación orotraqueal. El número de intentos para el paso de sonda nasogástrica con guía es mucho menor en comparación al no uso de la misma. Además las deformaciones, que fueron en su mayoría enrollamiento, se presentaron principalmente cuando no se usa guía, y las complicaciones presentadas, el sangrado nasal que solo se presentó en el grupo B. Por lo tanto, y de acuerdo al análisis estadístico, se recomienda el uso de guía esofágica para el paso de sondas nasogástricas en paciente entubado.
