A Novel Cement System to Ensure Slurry Stability in Horizontal Well
Authors: Doan Angela Anh , Holley Andrew Christopher , Li Li , Kellum Matthew Grady
Published: March 2017

Typical additives used to help suspend cement slurries at high temperatures include either biopolymers, such as polysaccharides, or synthetic polymers. The biopolymers typically degrade at elevated temperatures while the synthetic polymers tend to severely thermal thin leading to inadequate performance from either. This work describes an additive to improve cement slurry stability at higher temperature ranges in horizontal well.

A modified thickening time test, commonly referred to as a dynamic settling test, was used to demonstrate the stability of cement slurries at high temperatures. Free fluid tests were also performed where the cement slurries were exposed to downhole conditions prior to evaluating their stability. Ambient rheology profiles were examined to assure that the slurries can be mixed, pumped, and placed without excessive pressures. The effectiveness of this novel additive on fluid loss control is also exhibited by performing stirred fluid loss tests at elevated temperatures.

Cement slurry stability is especially difficult to achieve in long, horizontal well cementing, where the slurry is exposed to high temperatures over long periods. The novel cementing additive presented here can help simplify otherwise complex cement slurry designs, which are needed to help meet all operational requirements. In particular, the material helps eliminate the need for excessive viscosifying agents in combination with large quantities of dispersant in order to maintain slurry stability at higher temperatures. The paper compares the effectiveness on cement slurry properties such as stability, free fluid, rheology, and fluid loss control. The tests were conducted from 200 °F to 400 °F in the laboratory at varying concentrations and cement densities. The problems, current solutions, newly developed solution and case history will be discussed in the paper.

The work detailed shows that the new additive improves high-temperature cement slurry stability without high surface rheology and the associated mixing/pumping challenges. By providing this stability for horizontal wells, the cement slurry will prevent undesirable consequences which could result in remedial work, poor fracture treatment, communication between zones, and millions of dollars spent in additional completion costs and lost production.
Combination of Light Annular-Mud Drilling and Downhole Isolation Valve for Drilling in Fractured Gas Reservoir, A Case Study
Authors: Ezer Enos Eben , Pratama Andi , Irawan Fikri
Published: March 2017

The South Sumatra Field in Indonesia produces from a high deliverability gas reservoir with the gas rate of each well around 50 to 200 MMSCFD. The primary target is the fractured network present in the Pre- tertiary Granite/Andesite while the secondary target is the Tertiary carbonate.

In the past decade, Light Annular Mud Cap Drilling (LAMCD) is one of Manage Pressure Drilling (MPD) methods that has been frequently applied to drill in the surrounding areas of South Sumatra's oil and gas fields. The LAMCD method allows drilling to continue despite experiencing total loss of circulation in the fractured reservoir. Sacrificial fluid, usually fresh water, is injected down into the wellbore through the drill pipe. Viscous fluid with the density slightly lower than the pore pressure is injected intermittently into the annulus. The challenge occurs prior to tripping out where the well needs to be balanced. The killing operation contributes additional cost from the lost circulation materials, additional operation days or non-productive time (NPT) and inflicts damage into the reservoir due to the injected LCM.

The downhole isolation valve (DIV) system is integrated into the 9-5/8″ casing string to cope with the challenge. By using this system, the requirement to kill the well while tripping out is eliminated. The successful utilization of LAMCD and DIV is elaborated in this paper as part of the drilling program and the combination of the two principles are applied. This paper focuses on the utilization of LAMCD and DIV in a case study of Drilling Well X which was drilled in the South Sumatra Field.

Published: March 2017

When the oil price is down, the gloves come off! Maximizing the full potential of closed-loop drilling (CLD) techniques to achieve dynamic well control and effectively slash costs is one often overlooked solution: Leveraging on the experience of numerous operations, this paper will showcase the operational impact of CLD to demonstrate why CLD technologies are one of the most underutilized performance drilling tools available to the market, yielding operational process safety improvements and cost-savings unattainable with conventional methods.
Reducing Operational Spend: Cost-Savings Analysis of Proactive MPD Utilization in a Deepwater Setting

Published: March 2017

Some operators estimate that lost circulation and well control events contribute to nearly 30% of total wellbore costs. In challenging deepwater drilling frontiers in which risks, nonproductive time (NPT), and associated costs are most substantial, the optimum drilling solution uses vessels equipped for managed pressure drilling (MPD).

Land operators traditionally rely on MPD technology as a contingency plan to overcome obstacles; however, deepwater operators tend to be more reluctant to adopt this practice because of the belief that cost of installation exceeds the cost of setbacks. On the contrary, MPD technologies enable the operator to significantly reduce fluid losses, NPT, and costs associated with wellbore-related pressure events. In fact, one example is the corrective responsiveness provided by the MPD variants of pressurized mud-cap drilling (PMCD) and floating mud-cap drilling (FMCD) can reduce costs associated with fluid losses by up to 40%.

This paper will evaluate the economic benefits of a proactive MPD installation. In a conventionally drilled, deepwater well with an MPD-ready rig in Brazil, the MPD stack was not installed on the riser and total losses were experienced resulting in 13 days of NPT. An economic analysis cross-comparing the cost of having an MPD stack installed for contingency use versus having the equipment on standby during conventional drilling will illustrate the cost reduction that an MPD-ready vessel provides.

Published: March 2017

The Influx Management Envelope (IME) proposed by Culen et al. (2016) is an advanced, innovative way to assess influx conditions in Managed Pressure Drilling operations, offering an improved tool for the decision making process. This work presents the process of developing the IME concept on a real deepwater MPD operation for the first time. Limiting factors such as: shoe integrity, maximum surface pressures, and mud gas separator (MGS) flow rates (gas and liquid) have been taken into consideration in the process of developing a set of Influx Management Envelopes for three different hole sections. Two methods were used for developing the IMEs: Single bubble approach, as described by Culen et al.; and hydraulic modeling using a commercial transient, multiphase flow simulation software package. A comparison of the results from the single bubble calculation versus simulation methods is presented, highlighting the impact of gas dissolution and dispersion on the manageable influx volumes in MPD. Additionally, the IME design process includes provision for advanced alternatives for safe handling and removal of influxes within the limits of the primary barriers and those of the surface equipment.
Enabling New Techniques: Nitrogen Gas Qualification and Testing of a Rotating Control Device

Published: March 2017

Managed pressure drilling (MPD), which has been heavily refined and readily practiced in offshore and deepwater operations, could open many doors to untapped potential on land—a concept often underestimated. Operators look to MPD technologies—for example, multiphase MPD or drilling gas—to access challenging or partially depleted wells when the conventional approach has failed or is economically unfeasible. One critical technology component that enables drilling with gas is the rotating control device (RCD), a pressurized secondary well control barrier that contains and diverts flow at surface. Coupled with an MPD system (choke, coriolis meter, etc.), the RCD enables early kick detection and the ability to manage the annular hydrostatic pressure profile using surface backpressure. Adding to the well control benefits realized by the RCD is its sealing capabilities.

Weatherford conducted nitrogen gas testing of RCD elements in accordance with API 16RCD testing criteria—the industry's first testing of RCDs for gas-tight sealing. Pressure control, MPD-enablement, and gas-tight sealing are the perfect combination of RCD capabilities that will enable new techniques for drilling optimization in depleted reservoir sections. This paper will detail the inherent challenges of RCD gas-tight sealing and shed light on the significance that proven testing could deliver to the market for empowering new techniques that could lead to an unforeseeable number of drilling triumphs in the near future.

When compared to conventional drilling, MPD techniques provide a valuable tool to build challenging wells and reach new reservoirs. As MPD and MCD techniques lead to major changes on the way wells are drilled, the completion projects must be also adapted to this new scenario.

In order to fully use MPD capabilities it is necessary to work with statically underbalance fluids. This fact may not be an issue during the drilling phase with the RCD, but impacts completion, as the RCD, which is suitable for a drillpipe, is not suitable for all completion strings and equipment. For MCD scenario, the necessity of periodic or constant injection down the annulus affects some completion equipment.

Project requirements, safety standards, equipment capability and operational procedures must be reviewed, in order to cover the different scenarios of MPD (SBP) and MCD (FMCD and PMCD) wells. New completion standards were developed for deepwater and ultradeewater wells on MPD/MCD completion projects and sometimes even a full new completion design was required due to MPD techniques used.

This paper presents the development history, results and considerations made for completion with MPD/MCD on Petrobras offshore wells in Campos and Santos Basins located in Brazil offshore.
Documenting Trends in Land‐Use Characteristics and Environmental Stewardship Programs on US Golf Courses

Core Ideas

A survey of land‐use characteristics and environmental stewardship programs on US golf courses was conducted in 2015 as a follow‐up to an initial, 2005, study.

There were significant acreage reductions in maintained turf, as well as in overseeded and irrigated turf.

Trends in decreased acreage came about primarily through a combination of voluntary reductions in acreage and a net decrease in the number of golf facilities in the USA.

Variations in land‐use allocations occurred regionally, as well as for public compared with private facilities and 9‐hole compared with 18‐hole facilities, suggesting that climate, economics, and even real estate values are involved in these decisions.

Since an initial survey that documented land‐use characteristics and environmental stewardship programs for 2005, the acreage for an average 18‐hole golf facility has changed little, with a median acreage of 151 acres in 2005 and 150 acres in 2015. In contrast, the acreage of maintained turf on 18‐hole facilities has decreased significantly during that same period, from 99.2 acres (or 66% of 18‐hole facility acreage) to 95.1 acres (or 63% of 18‐hole facility). Natural or native vegetation comprises approximately 17% of 18‐hole facility acreage, while the remaining acreage is composed of water features (4.2%), buildings, (1.5%), bunkers (1.6%), and parking lots (1.6%). The acreage of winter overseeded turf in the Transition, Southwest and Southeast regions has decreased by 49% since 2005. Trends in turf‐type use have varied only slightly since 2005, with bermudagrass (Cynodon spp.) making up 34% of all US acreage, followed by Kentucky bluegrass (Poa pratensis L.) (23%) and annual bluegrass (P annua L.) (11%). The observed reductions in golf course facility and maintained turf acreage since 2005 were the result of an interaction between a net decrease in the number of facilities in the United States and voluntary reductions in the size of facility features. The most commonly cited reasons cited for turf reductions included cutting the costs for water and labor, but also for fertilizers, pesticides, and energy.
THE FORMATION OF THE RUSSIAN BORDER IN THE UPPER OB-IRTYSH AREA IN APPRAISALS OF SCIENTISTS AND TRAVELERS OF THE XVIII CENTURY
Authors: Bobrov D. S.
Published: March 2017

The article represents the experience of distinguishing and reconstruction of the views of scientists and travelers of the XVIII century on the formation of the Russian border in the Upper Ob-Irtysh area. The emergence of the historical and geographical images is considered as a direct consequence of the lack of delimited and demarcated border between the Russian Empire and the Dzungar Khanate, and then the Qing Empire. The source basis of the publication is composed by writings of significant for the history of region scientific figures: G. F. Miller, G. V. Gennin, I. P. Falk, P. S. Pallas. The study was methodologically grounded by the "close up" method. Research statements are analyzed in detail in the context of the scientists’ targets, attracted sources and circumstances of the implementation of the expeditions. The author identifies the ideologies with predominance of archetypal ideas, pays special attention to P. S. Pallas’s concept of "natural border" and his observations on the mode of functioning of the state borders, finally coming to the conclusion about fragmentariness, eclecticism and multivariatness of historical and geographical images of the Russian border.

Authors: Kolmogorova L. S. , Balabekyan E. S.
Published: March 2017

The analysis of children’s preparedness for studying at school indicates the problems in preschool training organization. In spite of numerous investigations the effectiveness of different preschool children training forms is not discovered yet. On the basis of teaching experts’ experience and present preschool training programmes the conception of preschool training was developed by the authors’ group which included L. S. Kolmogorova, L. A. Nikitina, L. I. Shvarko, O. I. Davydova, O. R. Meremyanina. On the basis of this conception the programme “My World” oriented on preschool training of children aged from 5,5 – 6 was developed. Since the aim was to balance the starting opportunities for children from different social levels, it became necessary to check the effectiveness of the educational-methodical complete set “My World”. To solve this problem the experimental investigation was held in 2011 – 2016 on the basis of the groups for pre-school training of Barnaul and Novosibirsk schools and Children’s Educational Institutions. In the investigation theoretical (the analysis of the bibliography) and empirical (the testing, question-and-answer discussion, investigation of the activity) methods were used. The results of the experimental investigation show the increase of the children’s preparedness for school. This confirms the effectiveness of the preschool training programme “My world” during the activity of the elder pre-school children.
DYNAMICS OF THE COSTUME IN CHEKHOV'S PROSE
Authors: Abieva N. M.
Published: March 2017

The article is addressed to the poetics of costume in Chekhov's prose. This aspect of prose has not been studied and gives material for research, which adds relevance to the article. The author shows how in anecdotal plots the costume is represented as a characterological ("Once a year"), "metaphysical" ("The Station") and psychologically stressed detail ("Man"). Dynamics of the costume is indicated by a change in its semantics and functions. The romantic shawl in "The disgraceful story (something like a novel)" encompasses a coiled story about the peril of a "bookish" concept of life. The metamorphoses of the characters changing their clothes turn an archetypal plot upside down ("Living Goods"). Intertextuality item allows you to turn the story into a parody ("Green Spit"). In Chekhov's later prose a complication of costume features can be observed: in the novel "My Life" the costume, while existing in a tangle complex of the visual, the acoustic, the tactile and the olfactory, traces the story in the interplay of text overtones.
«THE NAMING DICTIONARY OF THE RUSSIAN LANGUAGE»: RESEARCH PERSPECTIVES
Authors: Zamilova A. V. , Satuchina T. U.
Published: March 2017

The article deals with the concept, project and originality of the new type of onomasiological naming dictionary formation. There are a number of psycholinguistic studies on the basis of the Naming Dictionary articles. The results of these studies show linguomarketing potential of the words-bionyms and their real function in company names, peculiarities of the native speaker linguistic consciousness, correlation lexicographic and “psychologically real” meaning of the word and peculiarities of the linguistic sign variation. The Naming Russian Dictionary reflects the knowledge about words in fundamentally new dimension: not according to the prescriptive function (in the current dictionary it is kept to the minimum) but in terms of the native speakers’ idea about word semantics and its reference with reality. An additional point is that the dictionary is made on the basis of the linguistic experiment. It provides not only enlargement of current linguistic studies in the sphere of the linguomarketology but it allows one to study an ordinary linguistic consciousness of native speakers of the Russian language.
SELF-EQUALITY AS A STRATEGY OF SPONTANEOUS TEXT GENERATION
Authors: Moskaltchuk G. G.
Published: March 2017

The article deals with the results of the psycholinguistic experiment which prove the influence of the self-equality strategy in the process of spontaneous reaction text generation as a reaction on the stimulus “human life”. The materials have been analyzed with the help of a special computer program which marks the reaction texts parameters: text size in words (from space to space) and in sentences as well as the text formula reflecting the finite integral state of the whole. It has been found out that the self-equality as the principle of structuring speech forming activity is also used when producing reaction texts. The form reflects the hidden laws of the text synergetics and its synchronization with the speech-thought processes of the human acting with lack of time, it shows the hidden laws of the text formation. The probability of the realization of the 7 dominant models of the text form in the experiment is 824 texts of 1 thousand, in the directed one – 705 texts. The text formats reflect the discretization of the inner textual information. The average text size in the free experiment is 27.82 words, in sentences – 2.64, in the directed experiment – 12.34 and 6.79 sentences correspondingly. The reaction texts set on one page are formed by the tested according to a selected pattern and have hardly any stylistic, graphic and punctuation difference. The forms generated in the process of experiment are more end-oriented with attractors located in the end alongside with the dominant sense.
SCIENTISTS AND TRAVELERS ABOUT BIYSK IN THE 19th – THE BEGINNING OF THE 20th CENTURY
Authors: Degtyarev D. S.
Published: March 2017

Biysk, being the second town of Altai of its size, attracted many scientists and travelers. They created colorful and unforgettable images of the town in the XIX – the beginning of XX century. 14 descriptions produced by 12 authors in 1810 – 1917 were analyzed to establish if the image corresponded with reality. There were rather different descriptions ranging from official geographical reviews to emotional lines of travel diaries. A comparative analysis allowed us to conclude that those images of Biysk were real in their description of dirty streets adjoining beautiful churches and comfortable fashionable hotels. Still, subjective factor influenced to the images of Biysk as well. Readers in the XIX century could trace all changes of the life of the town – from a fortress on the boarder to a small trade town (where inhabitants hadn’t got even a sundial) and then to the important economic and cultural center of the region – “the window to Europe” for Mongolia”. The image of the town gradually changed from negative to neutral and positive. It was determined by real economic and cultural development of Biysk. The result of this exploration allows one to define the way a Russian regional town was represented in informational area of the country in XIX – the beginning of XX century.
P. SABANSKY'S CAMPAIGNS TO TELETSKOYE LAKE AND F. PUSHCHIN’S CAMPAIGNS TO THE BIYA RIVER: TIME, REASONS, CONSEQUENCES

Published: March 2017

The campaigns of Tomsk service people F. Pushchin and P. Sabansky to the river Biya and Teletskoe Lake are well known to Siberian historians. The historiography of these campaigns is poor and limited to the works of G. F. Miller, I. E. Fisher and A. P. Umansky. The source base these researchers relied on is poor as well. Until recently it was limited to the four documents of the "Tomsk archives", three of which were published by A. I. Andreev in the annex to the "History of Siberia" by G. F. Miller. Until recently the interpretation of these campaigns by I. Fisher and A. P. Umansky were beyond doubt. However, a comparative analysis of the documents, which the researchers used to describe the campaigns of F. Pushchin and P. Sabansky, showed their contradictions and incorrect dating, also the reasons for these campaigns were unknown. In the collection of the Siberian order of The Russian State Archives Ancient Acts we discovered a statement about the campaign of P. Sabansky on Teletskoe Lake which settles these differences and makes it possible to set the exact time, the causes and the sequence of the campaigns.

Authors: Tsyryapkina Yu. N.
Published: March 2017

The paper characterizes the process of creation of medical infrastructure and first aid system to immigrant and indigenous people in Tashkent and the Tashkent district in the second half of the XIX – the beginning of the XX century by the imperial authorities. The purpose of the paper is to reveal the medical condition in the second half of the XIX – early the XX century in Turkistan, types and amount of medical care, which was provided to the indigenous population of the region, by studying biographical and source materials. The paper draws attention to the fact that initial medical assistance to the immigrant population and then the indigenous dwellers of the region were provided by surgeons who settled mainly in Tashkent and the major cities of Turkestan. I. P. Sheverdin was one of the first surgeons who founded the rural hospital in remote place of Tashkent district – village Tillyau in 1899 – 1903, whose asceticism and dedication the inhabitants of this village still remember. It is shown that medical services in Tashkent and the Tashkent district in the pre-revolutionary period developed slowly, which corresponds to the first stage of initiation of the indigenous population of the region to the modern achievements of medicine.

Published: March 2017

Nanomaterials based on carbon nanotubes (CNT) and graphenes attract a lot of attention of researchers as the materials capable to raise the development of various industries to the new level, and first of all, of the chemical and electronic sectors. In addition to known experimental methods, new nanosystems are widely studied using advanced tools of quantum-chemical approaches. Modern theoretical methods are of great interest due to their ability to interpret known experimental facts and predict properties of non-synthesized compounds yet. This paper reviews results of theoretical studies performed using the density functional theory (DFT) methods to obtain data on the structure and electronic properties of single-walled CNT and graphene, modified with various impurities, with covalent-ionic and non-covalent binding mechanisms. New computational methods are briefly described that are currently employed to treat the dispersion interaction and enhance possibilities of DFT tools in systems where the van der Waals forces play a significant role. Particular attention is paid to the characteristics of carbon nanomaterials containing technologically important hydroxyl, carboxyl and amino groups. It is shown that the specific peculiarity of band structures of discussed in the literature CNT functionalized by OH, COOH, NHn and CONH2 groups is the partially occupied band in the neighborhood of the Fermi level, which directly affects the CNT conductivity. Modification of graphene layers is analyzed that interact with hydrogen, fluorine, bases of nucleic acids and the metal substrate surface. We also provide accuracy estimates for the calculations of interatomic bond lengths, interaction energy and band gap carried out in the literature using a variety of DFT approximations.

Luminescent glow occurring in a substance exposed to ionizing radiation (IR) in the process of heating, thermoluminescence (TL) is now an effective method of registration of radiation-absorbed doses. It is important to be aware that the correct absorbed dose when exposed to mixed radiation with unknown characteristics is determined in the material of detector as well as in materials similar in composition (Z eff) and density [1-3]. In this connection, it is expedient to use different types of detectors for solution of different dosimetric problems. This study gives a comparison of the performance characteristics of TLD-K thermoluminescent detectors [4, 5], made of sodium silicate glass ceramic with the characteristics of IR detectors made of luminophors based on lithium fluoride monocrystals containing impurities of titanium and magnesium (TLD -100) [6, 7] and an anion of defective aluminum oxide (TLD-500) [8-11] widely used in thermoluminescence dosimetry. Comparison of a number of parameters that are relevant to the use of detectors in dosimetric monitoring of environment favors TLD-K detectors. The studies were carried out on the territory of the Kemerovo region.

In 1993, karyotyping of Opisthorchis felineus sporocysts, isolated from aquatic mollusks Bithynia inflat a in the industrial wastewater of the Siberian Chemical Combine discovered cytogenetically modified 12-chromosome specimens. In 2012-2013, a repeated study of the spread of these mutant trematodes in the lower course of the river Tom was carried out. It was established that specimens with sporocysts of O. felineus having 2n=12 were found in 8 of 10 places of catching. The caught goldfish were used to isolate metacercariae to infest golden hamsters in the experimental conditions. After 5 months, the hamster livers were processed to extract marita specimens and the number of chromosomes in their ovaries and testes was cytogenetically determined. The results of analysis of the spread of O. felineus carried out by this method showed the presence of 12-chromosome form of the Opisthorchis marita in all places of fishing out in the lower course of the river Tom. Analysis of the 12-chromosome karyotype allows to conclude that this mutation was a result of Robertsonian fusion of chromosomes 3 and 6 of 14-chromosome form of karyotype.

This paper is aimed to develop stabilizers with the conserving effect that helps to prolong the expiry date with the blood stabilization up to the relevant processing, including the fractionation characteristic selection. Theoretical and experimental studies are performed to comply with the tasks at hand at the “Bionanotechnology” Chair of the Kemerovo Institute of Food Science and Technology (University). The entire research cycle consisted of several correlated stages. The national and international literature available was analyzed to state objectives and tasks at the first stage. Whole blood stabilization parameters are selected with the concurrent conservation to improve the stability of erythrocyte membranes. The best value of the separation factor is selected wherein the application condition of high separation factor values is taken as the baseline for the blood fractionation. The process of citric acid influence is analyzed as the preservative agent on the blood viscosity, blood pH and total bacterial content. A calibration dependence graph of the separating unit rotation velocity (separator, centrifuge) is worked out of the unit rotation radius. The fractional composition of the derived protein components of red blood cells of the bovine cattle and porcine bloods is analyzed to prove the benefit of fractionation characteristics obtained. The following fractions are revealed in the packed red cells as follow: haptoglobin, fibrinogen, globulin, one of its three forms, hemoglobin, the protein of the platelet-leukocyte group.

This paper presents an automated medicinal plant leaf identification system. The Colour Texture analysis of the leaves is done using the statistical, the Grey Tone Spatial Dependency Matrix(GTSDM) and the Local Binary Pattern(LBP) based features with 20 different  colour spaces(RGB, XYZ, CMY, YIQ, YUV, $YC_{b}C_{r}$, YES, $U^{*}V^{*}W^{*}$, $L^{*}a^{*}b^{*}$, $L^{*}u^{*}v^{*}$, lms, $l\alpha\beta$, $I_{1} I_{2} I_{3}$, HSV, HSI, IHLS, IHS, TSL, LSLM and KLT).  Classification of the medicinal plant is carried out with 70\% of the dataset in training set and 30\% in the test set. The classification performance is analysed with Stochastic Gradient Descent(SGD), kNearest Neighbour(kNN), Support Vector Machines based on Radial basis function kernel(SVM-RBF), Linear Discriminant Analysis(LDA) and Quadratic Discriminant Analysis(QDA) classifiers. Results of classification on a dataset of 250 leaf images belonging to five different species of plants show the identification rate of 98.7 \%. The results certainly show better identification due to the use of YUV, $L^{*}a^{*}b^{*}$ and HSV colour spaces.
TERM WEIGHTING BASED ON POSITIVE IMPACT FACTOR QUERY FOR ARABIC FIQH DOCUMENT RANKING

Published: March 2017

Query becomes one of the most decisive factor on documents searching. A query contains several words, where one of them will become a key term. Key term is a word that has higher information and value than the others in query. It can be used in any kind of text documents, including Arabic Fiqh documents. Using key term in term weighting process could led to an improvement on result’s relevancy. In Arabic Fiqh document searching, not using the proper method in term weighting will relieve important value of key term. In this paper, we propose a new term weighting method based on Positive Impact Factor Query (PIFQ) for Arabic Fiqh documents ranking. PIFQ calculated using key term’s frequency on each category (mazhab) on Fiqh. The key term that frequently appear on a certain mazhab will get higher score on that mazhab, and vice versa. After PIFQ values are acquired, TF.IDF calculation will be done to each words. Then, PIFQ weight will be combine with the result from TF.IDF so that the new weight values for each words will be produced. Experimental result performed on a number of queries using 143 Arabic Fiqh documents show that the proposed method is better than traditional TF.IDF, with 77.9%, 83.1%, and 80.1% of precision, recall, and F-measure respectively.

Aim: To investigate the relationship between metabolic parameters and thyroid hormone changes which occur in patients treated with thyroid replacement therapy following total thyroidectomy. Material and Method: The study comprised 30 patients who underwent total thyroidectomy. Evaluations were made preoperatively and after 6 and 12 months postoperatively. Body mass index was calculated by recording height and weight of all patients, waist size was measured, arterial blood pressure was measured with a sphyngomanometer on the right arm after 10 mins of rest. Peripheral blood samples were taken after 12-hour fasting for the evaluation of low density lipoprotein, high density lipoprotein, total cholesterol, triglyceride, fasting glucose, fasting insulin, thyroid stimulating hormone, free T3, free T4, C-reactive protein, and haemoglobin A1c values.Results: In the postoperative 1-year follow-up, a significant increase was determined in total cholesterol, low-density protein and triglyceride levels, which are related to cardiovascular risk, but no significant change was determined in high density protein levels. In addition, a significant increase was determined in the postoperative trend of both systolic and diastolic arterial blood pressures compared to the preoperative values.Conclusion: Although euthyroid was achieved with follow-up of thyroid functions in the patients who underwent bilateral total thyroidectomy, it was found that there could be changes in metabolic parameters. Therefore, with close monitoring of the metabolic profile of these patients, it can be recommended that lifestyle changes are made when medical intervention is insufficient.

Authors: Keller Patricia Ingrid
Published: March 2017

El objetivo del presente estudio es analizar el papel de la cultura en la implementación de estrategias para la sostenibilidad. Se trata de identificar principalmente las causas culturales que suelen inducir a la brecha entre la estrategia intencionada por un lado y la realmente implementada y los resultados, por el otro. Utilizando la Teoría de la Economía de las Prácticas de P. Bordieu, la Teoría de Administración estratégica y aspectos teóricos de la Sostenibilidad, se ha arribado a posibles explicaciones, luego de formular, llevar a cabo e interpretar entrevistas realizadas a empresarios de medianas empresas, vinculados a la implementación estratégica.
ESTUDIO DE LA RELACIÓN ENTRE LA RESPONSABILIDAD SOCIAL EMPRESARIAL Y LA IMAGEN INSTITUCIONAL EN EL SECTOR PRODUCTIVO DE LADRILLOS. CASO DE UNA LADRILLERA REGIONAL
Authors: Espinoza Luis
Published: March 2017

El presente artículo tiene la finalidad de presentar los principales resultados obtenidos a partir del estudio de la relación entre la responsabilidad social empresarial y la imagen institucional en el sector productivo de ladrillos, enfocándonos en el caso de la Ladrillera Martorell. La evaluación se realizó el año 2015. Las unidades de investigación para el presente estudio fueron 82 colaboradores. Metodológicamente la investigación fue inicialmente descriptiva para culminar en un procedimiento correlacional; asimismo, se consideró un diseño no experimental y transversal. La técnica de recolección de datos utilizada fue la encuesta y el instrumento el cuestionario. El estudio evidencia en el análisis descriptivo univariado de cada variable que la responsabilidad social empresarial y la imagen corporativa se encuentran en un nivel favorable de aceptación de los trabajadores. Finalmente la responsabilidad social empresarial se relaciona significativamente con la imagen corporativa debido a que el coeficiente rho de Spearman es de 0,827 y el pvalor es 0,00 menor al nivel mínimo de significancia, que es 0,05. Por tanto, se hace necesario proponer un modelo sistémico de responsabilidad social para la empresa con la finalidad de mejorar la imagen institucional.

El propósito de este trabajo es investigar el comportamiento y los beneficios percibidos de los consumidores en la ciudad de Arica, Chile mediante encuestas y su análisis con un modelo de ecuaciones estructurales. Con ello se pretende llenar un vacío en cuanto a estudios de esta clase en el mercado local, permitiendo a las empresas locales y a las que proyectan instalarse disponer de información útil para el diseño e implementación de sus estrategias de marketing. A partir de la investigación se ha determinado que los consumidores locales perciben los beneficios de ahorro, calidad y conveniencia agrupados como beneficios utilitarios, y los de expresión de valor, exploración y entretención agrupados como beneficios hedónicos. El beneficio del ahorro no aparece como el más relevante a la hora de escoger un producto.
GLOBALIZATION AND INEQUALITIES IN DEVELOPED ECONOMIES: KUZNETS WAS NOT RIGHT
Authors: Berumen Sergio A. , Pérez-Megino Luis P.
Published: March 2017

In this paper we first review the concepts of Globalization and Inequality, paying special attention to the conclusions reached previously by Simon Kuznets and his followers. Later we carry on with an international comparison between Sweden and the United States for the period 1913-2012. We depict the evolution in inequality levels for both countries, based in two main indicators: the Gini Index and the top 1% income share. Our findings point out that inequality has strongly risen in the United States whilst Sweden’s level of inequality is not far from the one presented immediately after the World War II. These results may indicate Sweden’s higher ability to deal with the globalization aftermaths.
ÁRBOLES DE DECISIÓN: DECISIONES EMPRESARIALES BAJO LA SOMBRA DE UN BUEN ÁRBOL.
Authors: Pincheira Varas Andrea
Published: March 2017

Sostenemos que para alcanzar el éxito en las organizaciones, la planificación, la ejecución y el control en la gestión deben apoyarse, necesariamente, en mecanismos técnicos que faciliten el análisis global y la toma de decisiones adecuadas, eficientes y oportunas.Como plantea Fineberg (1980), el árbol de decisión es uno de los modelos más utilizados como estrategia de análisis. Es un diagrama - construido a partir de la descripción- que representa secuencialmente las condiciones y las acciones de un problema. Asimismo, provee a los beneficiarios de una visión gráfica de la toma de decisión necesaria, especificando las variables, los escenarios y el orden en que serán efectuadas.Con la finalidad de introducir al estudiante al conocimiento de la técnica en comento, presentamos elementos teóricos y una aplicación práctica de ésta, la que incluye el análisis cualitativo y cuantitativo.

Human nature and stasis: On the influence of Thucydides on Hobbes’s science of politics
Authors: Milisavljevic Vladimir
Published: March 2017

This paper assesses the influence of Thucydides on Hobbes?s conception of man
and, more generally, on his model of ?Civil Science?. This influence can be
traced back to the time when Hobbes worked on his translation of Thucydides?s
history of the Peloponnesian War. Already at that time, Hobbes characterized
Thucydides as the ?the most politic historiographer that ever writ?, i.e. the
historian whose work contributed the most to the true knowledge of politics.
The main argument of the paper is that Hobbes?s admiration for the author of
the History of the Peloponnesian War can be best explained by Thucydides?s
ability to portray the essential conflictuality of politics. This thesis is
confirmed by a comparative analysis of some important themes in Thucydides?s
historical narrative and several major theoretical statements of Hobbes?s
anthropology and political theory. There is an unmistakable similarity, which
has often been commented on, between Hobbes?s account of the three principal
causes of conflict between individuals in the state of nature - Competition,
Diffidence and Glory - and the three main human instincts to which the
Athenians appeal, in a speech that Thucydides conveys, to justify their
striving for power. However, Thucydides influenced Hobbes mostly by his
descriptions of internal war. The final part of the article examines in this
light two topics from Thucydides?s famous description of the stasis which
took place in Corcyra - the impossibility of justice and the perversion of
language in time of sedition in the polis.
Revitalization of automotive industry in Serbia: Is the role of fiat crucial?
Authors: Beraha Isidora
Published: March 2017

This paper deals with the analysis of the economic effects of Fiat investment
on the development of automotive industry in Serbia. The main objective of
the research is to determine why the expected local suppliers base was not
created, and whether it was mainly influenced by Fiat. The research is based
on the concept of clusters as effective instruments that enable the
integration of local suppliers into supply chain of global automotive
manufacturers, as well as on the assumption that the strength of clusters is
primarily determined by the presence of large, powerful enterprises. The
empirical research was conducted using econometric analysis (stochastic
frontier analysis) and statistical t-tests on panel data consisting of 40
enterprises operating in the Serbian automotive sector. The aim was to
analyze whether the presence of large enterprises increases the cluster
performances in Serbian automotive industry. The empirical research results
showed that large companies, on average, decrease cluster performances thus
pointing out to the conclusion that the absence of large and powerful global
companies in the automotive cluster of Serbia, i.e. the absence of Fiat, has
significantly reduced the possibility of creation of local suppliers base in
the Serbian automotive sector.
