Abstract
Steam Assisted Gravity Drainage process has been done and successfully implemented for the producing of the Canadian heavy oils and bitumen. Although it is commercially proven, but it still uses high energy intensity and has high environmental impact. To reduce those side effects, hybrid steam-solvent is proposed as one of the alternative processes in order to reduce the problems.
There are some challenges in reservoir heterogeneity correlated with steam-solvent injection. In conventional process, spreading of steam-solvent is able to be controlled using bottom-hole pressure injection and liquid production rate. In heterogeneous reservoirs however, each part of the horizontal well will have different optimum operation conditions.
This paper presents a strategy for hybrid steam-solvent optimization using ICVs (interval control valves) to maximize energy efficiency. To provide an overview of this phenomenon, the synthetic reservoir model is built from McMurray Formation. Bitumen saturation distribution and rock properties are created using geostatistic method and validated using several wells. The reservoir models were run using several operating conditions to achieve the most realistic interpretation. Sensitive variables are steam injection pressure, length grouping of perforations, managing of perforation openings, and solvent concentration. Afterwards, steam efficiency and solvent affectivities are evaluated during 15 years of project life.
Simulation results show that the managing of steam injection will increase heat efficiency up to 7.4% compared with conventional perforations. Furthermore, in the hybrid steam-solvent injection, the recovery factor will be better 8% compared to without adjustment in solvent concentration of 10% volume. Finally, retention of solvent injection can also reduce until 30% by this managing of processes.

Abstract
A challenging cirmcumstance unfolded in the initial lateral 6 1/8-in section of a sidetrack horizontal well drilled for Kuwait Oil Company in North Kuwait. The original well was drilled by a competitor whose BHA became stuck in the "Mauddud A" layer formation at 9892 ft MD / 7509.5 ft TVD, in the initial part of the lateral section. Several failed fishing attempts resulted in a cement plug, burying the RSS and LWD BHA with radioactive sources.
Kuwait Oil requested Baker Hughes' expertise to sidetrak and drill the 6 1/8-in lateral section. The distance from the 7"-in liner shoe to the top of the fish was only 74ft. The top of fish is 7509.07 ft TVD, and the bottom of fish 7523 ft TVD.
A motorized rotary steerable system (RSS) was proposed by Baker Hughes to perform the sidetrack. No cement was encountered during the first 28 ft of sidetrack. The motorized RSS BHA successfully sidetracked the well, passing the top of fish by 2 ft, marking the first high angle sidetrack completion with RSS and modular motor BHA. After completing the sidetrack, the motorized RSS BHA was pulled out of hole (POOH) to pick up the LWD tools. The lateral section was drilled to well total depth (TD) with the BHA, and included the distance to bed boundary and triple combination logging while drilling (LWD) tools. Reservoir navigation services (RNS) (Geosteering) was utilized to geosteer the lateral section of the Mauddud B reservoir section. The proactive geosteering services enabled 97.7 % of reservoir contact to remain in the target reservoir (of the Mauddud B formation) despite encountering two faults with 10ft TVD upthrow.
The well was TD at 12832 ft MD / 7552.9 TVD-RT, near the bottom of the Mauddud B formation.

Abstract Double balanced translocations are particularly rare and the risk of a fetus with an unbalanced chromosomal anomaly is greater than for single translocation carriers. In this present case, we describe an interesting family history which included three generations. A couple, married for 4 years, was referred to the genetic clinic due to infertility and family chromosome anomalies. A GTG-band chromosome analysis indicated that the male partner’s karyotype was 45,XY, t(3;18)(q11;ptel)t(13;14)(q10;q10). The same double balanced translocation was found in two others family members.

Abstract
The aim of the study was to implement in vitro cultivation of L. intracellularis strains using ATCC 55783 and vaccine strains, and McCoy cells (ATCC CRL-1696). The infection was monitored by daily observations under phase contrast microscope. Indirect immunostaining using monoclonal antibody was also performed. Large number of S-shaped, moving bacteria were found in the cell medium in cultures infected with ATCC 55783 and vaccine strain. Immunostaining revealed a high number of multiple cell-associated or intracellular red stained bacteria in the infected cultures. This study describes for the first time in vitro cultivation of L. intracellularis in Poland, which creates further perspective for more advanced research on this bacterium.
Did EU candidacy differentiation impact on the performance of preaccession funds? A quantitative analysis of Western Balkan cases
Authors: Denti Davide 
Published: October 2013

Abstract
After four years of implementation the EU funds for candidate countries, the Instrument for Pre- Accession Assistance (IPA), has shown a mixed performance, resulting in a statistically limited level of use of IPA funds in most target countries, though with some variance. This article intends to test the hypothesis linking such a differentiation with the presence or absence of the official status of candidate country. The analysis of the funds allocation levels, the funds absorption levels and the progress in administrative reforms nevertheless shows that candidacy status is neither a sufficient nor a necessary condition for a good IPA performance. Rather, the data show that the IPA funds were able to catalyse a good progress only in those target countries characterised by an average adaptation pressure, but not to spur laggards and frontrunners, recalling the hypothesis put forward by Radaelli in his analysis of the outcomes of Europeanisation.
Development of a Decision-Making Algorithm for Determination of the Optimal Land Use Function
Authors: Biłozor Andrzej 
Published: October 2013

Abstract
Although the arrangement of urban space use functions is the outcome of the activity of many different entities, it is not a random activity, as there are general principles guiding the creation process of such a structure. The correct selection and arrangement of areas in a city for different types of use is of significant importance for the fulfillment of economic, functional and planning needs of the city. The concept of land division therefore has a decisive effect on the spatial structure of every city.
The growing shortage of free urban space causes, or even forces, its optimal use. The optimization of land use functions in a city aims to verify mismatched land functions and replace them with functions best matched to the present natural and anthropogenic features. Adaptation of problem areas generating “spatial conflicts” should be based on the opinion of the city’s residents to reflect their current needs as well as on economic calculations. This paper presents a procedure for determining optimal states of land use as a tool in the urban space management process. The developed algorithm is designed to form the basis for conducting spatial monitoring, serving to analyze and verify individual land management forms in order to minimize the costs of transformation and maximize income.
Groups with every subgroup ascendant-by-finite
Authors: Camp-Mora Sergio 
Published: October 2013

AbstractA subgroup H of a group G is called ascendant-by-finite in G if there exists a subgroup K of H such that K is ascendant in G and the index of K in H is finite. It is proved that a locally finite group with every subgroup ascendant-by-finite is locally nilpotent-by-finite. As a consequence, it is shown that the Gruenberg radical has finite index in the whole group.

Summary
The aim of this study was to determine the frequency of extracardiac pathology in neonatal patients with suspected congenital heart disease referred to undergo multidetector computed tomography (MDCT) angiography in Vilnius University Hospital Santariskiu Klinikos. The safety of MDCT angiography (intravenous contrast media volume injected, scanning time and exposure to ionising radiation) was also evaluated.
Patients and Methods: During the period of 2006-2012, in Vilnius University Hospital Santariskiu Klinikos 186 pediatric patients were referred to undergo MDCT angiography of whom 71 were neonates with suspected complex congenital heart disease (CHD) and extracardiac pathology.
Results: Sixty nine (97.2%) of referred neonates were found to have extracardiac pathology (36 had extracardiac vascular pathology only, 4 - extracardiac non-vascular pathology only and 29 - both extracardiac vascular and non-vascular pathology). In 47 patients diagnosis of extracardiac pathology was verified intraoperatively. Remainder (n = 24) of the group were not operated (12 patients died because of hemodynamic instability and inoperable complex CHD, 9 patients were scheduled for later surgery, in 3 patients surgery was not indicated). Mean contrast media volume used was 4.18±1.03 ml, mean scanning time was 1.07±0.77 s and mean effective radiation dose was 2.8± 0.69 mSv. No adverse reactions or complications were observed.
Conclusions: MDCT angiography is accurate and safe method in diagnosis of complex congenital heart disease with extracardiac pathology.

Published: October 2013

Introduction: The prevalence of suicide has been increasing globally in all age groups. There is dearth of literature on suicide among younger patients from developing country. The objective of this study was to find out the prevalence and cause of suicide as well as to identify the vulnerable groups of children and young adults to suicide. Materials and Methods: This is a retrospective observational study. Data was collected from the Police Head Quarters in Kathmandu and included all completed suicide cases of less than twenty one years of age from January 2005 to December 2009. Results: There were a total of 2172 documented cases of completed suicide in the age group between 4 to 21 years. The majority were female and belonged to the adolescent age group. The incidence of suicide showed an increasing trend within the five years of the study. A monthly breakdown of the cases revealed that the incidence of suicide was lowest in January and February and peaked from April to October. Hanging was the most common mode of suicide followed by poisoning and drowning. The reason for suicide could be ascertained only among 25.5 % of cases. Domestic violence (35%), mental illness (24%), failure in academic achievement (15.8%) and end of a romantic relationship (8.7%) were found to be common causes of committing suicide. Of the 87 cases found who committed suicide because of academic failure 46.6% were at a grade ten level. Conclusions: Suicide in children and young adults in Nepal appears to be a concealed but serious problem requiring immediate attention and systematic efforts.

Authors: Ojha Anil 
Published: October 2013

Introduction: Ayurvedic remedies are popularly used in practice for long time in Nepal. It is regarded as safe and free from side effects. However there are published reports of the high content of heavy metals like lead in such preparations. No such study has been done in Nepal looking at the lead content in ayurvedic preparations. The aim of this study was to detect the level of lead in commonly used ayurvedic remedies used in paediatric population if any. Materials and Methods: Seventeen samples were selected for lead estimation based on frequency of prescription and over the counter dispense. All of them were analyzed using Atomic Absorption Spectrophotometer (AAS) 6300 using flame mode. Results: None of the samples had detectable level of lead in parts per billion. Conclusion: Though this study did not detect lead in the seventeen samples of ayurvedic medicine, a larger study is needed involving large samples of these medicines with use of more sensitive equipment for testing.

BACKGROUNDUnderstanding of cancer outcomes is limited by data fragmentation. In the current study, the authors analyzed the information yielded by integrating breast cancer data from 3 sources: electronic medical records (EMRs) from 2 health care systems and the state registry.METHODSDiagnostic test and treatment data were extracted from the EMRs of all patients with breast cancer treated between 2000 and 2010 in 2 independent California institutions: a community‐based practice (Palo Alto Medical Foundation; “Community”) and an academic medical center (Stanford University; “University”). The authors incorporated records from the population‐based California Cancer Registry and then linked EMR‐California Cancer Registry data sets of Community and University patients.RESULTSThe authors initially identified 8210 University patients and 5770 Community patients; linked data sets revealed a 16% patient overlap, yielding 12,109 unique patients. The percentage of all Community patients, but not University patients, treated at both institutions increased with worsening cancer prognostic factors. Before linking the data sets, Community patients appeared to receive less intervention than University patients (mastectomy: 37.6% vs 43.2%; chemotherapy: 35% vs 41.7%; magnetic resonance imaging: 10% vs 29.3%; and genetic testing: 2.5% vs 9.2%). Linked Community and University data sets revealed that patients treated at both institutions received substantially more interventions (mastectomy: 55.8%; chemotherapy: 47.2%; magnetic resonance imaging: 38.9%; and genetic testing: 10.9% [P < .001 for each 3‐way institutional comparison]).CONCLUSIONSData linkage identified 16% of patients who were treated in 2 health care systems and who, despite comparable prognostic factors, received far more intensive treatment than others. By integrating complementary data from EMRs and population‐based registries, a more comprehensive understanding of breast cancer care and factors that drive treatment use was obtained.

AbstractDuring assessment of reinforced concrete structures, information about concrete properties can give a clearer insight into the prevailing reasons for premature degradation of structures. In this paper an overview is given of methods for local detailed inspection of concrete properties in corroding reinforced concrete structures. Recommended non‐destructive, semi‐destructive and destructive testing methods for determining mechanical and durability properties of concrete are given, together with some practical information about performing the method and analysing obtained results. Recommended criteria for evaluating concrete quality and potential risk of corrosion due to poor concrete performance are also given.
Research on intercrystalline corrosion, exfoliation corrosion, and stress corrosion cracking of Al–Zn–Mg–Sc–Zr alloy
Authors: Li B. , Pan Q. L. , Zhang Z. Y. , Li C. 
Published: October 2013

AbstractThe intercrystalline corrosion, exfoliation corrosion (EXCO), and stress corrosion cracking (SCC) of Al–Zn–Mg–Sc–Zr alloy were investigated by means of constant temperature immersion corrosion method, optical microscopy, transmission electron microscopy (TEM), and electrochemical impedance spectroscopy (EIS). The results show that intercrystalline corrosion, and EXCO susceptibility of Al–Zn–Mg–Sc–Zr alloy decrease gradually with increasing of aging time. Corrosion susceptibility order from low to high is as follows: OA > PA > UA > NA. The SCC susceptibility index of PA temper is more than OA temper at the same strain rate. According to TEM observation, with aging time prolonging, a part of η′ phases transform to η equilibrium phases, which become coarse gradually. The distribution discontinuity of the grain boundary precipitates increases. In addition, for Al–Zn–Mg–Sc–Zr alloy without EXCO, the EIS is comprised by a capacitive impedance arc at high frequency and an inductive impedance arc at low frequency. Once EXCO occurs, the EIS is composed of two capacitive impedance arcs at high frequency and at low frequency, respectively.
