Authors: Chan Brenda Wing Han , Lei Chi Tong 
Published: August 2016

Abstract
A Security Door Access Control System (SDACS) project involves a number of teams from different organizations with diverse project goals. One of the main challenges of such projects is the lack of a standard approach or common understanding to achieve a common goal among project parties. This research examines various management concerns for SDACS projects, highlights the expected common understanding for project participants, develops the project management constructs, and emphasizes on the resulting value of the project to all participants. A two-stage process of scale development and validation was conducted. First, six generic constructs were identified based on the Security Access Control System Framework. Next, a multi-item scale for each construct was developed with reference to the Result-Oriented Management Framework. Expert judges were invited to conduct manual sorting of the items iteratively until reliability and validity was reached. In the next stage, further refinement and validation were carried out with a synthesized survey instrument and a series of statistical testing followed. The finalized SDACS project management constructs and the related findings help reinforce the importance of a standardized management practice for SDACS projects. The value of this research not only benefits SDACS project managers but everyone who works on the project.

Authors: Popa Radu-Ioan 
Published: August 2016

Abstract
The present article follows an in-depth analysis of several relevant articles and major findings concerning the return to work of cancer patients, in various situations, from a manager and patient point of view, putting into discussion the effects and consequences of different factors that may influence the well-being of the patient at work and impact the organizational life. The concepts of returning to work and integration are scarcely analysed throughout the scholarly literature in the case of employees diagnosed with cancer, due to several reasons presented in the paper: from the complex topic of investigation that many studies fail to approach in terms of confidentiality, technical, ethical and moral grounds to the specific and difficult apparatus for research in the case of an even more complex, multiple instances and personalized manifestation long-term illness. In conclusion, the general framework solicits for a more integrated model of research and future multi-facet schemes for interventions, considering that there is a general consensus focusing on the need for connecting the health services with the employee and employer level, alongside stakeholders’ active participation.

Published: August 2016

Abstract
Using factor analysis of ecological niches, we found that Parus major has high marginality to such ecogeographical variables (EGVs), as normalized difference vegetation index, the altitude above sea level, the diffuse insolation, activity of chlorophyll, normalized difference water index. This species is highly specialized in relation to various vegetation indices. Based on the type of habitat preference map, we found that Parus major doesn’t implement all its potential pro-spatial niche. Considering the ecological niche of great tit on different levels of scale, we noticed certain features: first, a list of factors that influence the distribution of great tit significantly altered by changing the scale, secondly, the factors that play a significant role in spreading Parus major on level of total consideration losing their weight and relevance on closer inspection (when the scale down); third, although specialization of great tits changes with the scale of consideration but Parus major mostly specialized by vegetation index.

Published: August 2016

Abstract
Phenotypic and genotypic diversity of populations of species of the yellow wagtails in the space of their ranges in a wide sympatry reflects the mechanisms of reproductive isolation of species and forms of subspecies rank and features of microevolution group - polytypic complex Motacilla flava Linnaeus, 1758. The distribution of species of the yellow wagtails in the European part of Russia is sympatric. The purpose of this study was to investigate whether sympatric settlement led to any genetic separation between the populations of these species. 20 blood samples and 2 samples of eggs collected in areas geographically representing the MID and the southern Russian breeding populations of these species, including all juvenile ringed in 2012, were used. After the polymerase chain reaction (PCR) 4 types of the yellow wagtails group Motacilla flava L., 1758; M. feldegg Michahelles, 1830; M. lutea (S. G. Gmelin, 1774); M. cilreola Pallas, 1776 (Passeriformes, Motacillidae) were sequenced. After aligning the sequences of the gene cytochrome oxidase I, based on the comparison of genetic distances between these species phylogenetic tree of genus Motacilla was constructed. These results suggest that, despite the broad sympatry in nesting places, there is a selective mating between males and females of each species studied in spite of the free crossing and insulating mechanisms in populations.

Authors: Skyba Eleonora K. 
Published: August 2016

The purpose of the article is to analyze the relationship and interaction between gender identity and power relations in society; to study specific features of gender identity’s representation in the contemporary socio – cultural discourse; to examine the role of gender regimes in the process of reproduction of gender inequality. Methodology. For analysing the relationship and mutual influence of gender identity and power relations in society, and studying the mechanism of reproduction of gender inequality is methodologically important to use comparative and concrete – historical methods. Since many researchers noted that the content of gender identity in different historical and cultural contexts is changed, it sounds methodologically reasonable to study this problem on the dialectical position that allowed us to see that the basis of all social institutions is the «problem of ifference» justifying «the problem of domination». Paying attention with the nature of the process, it is extremely important to provide the principle of methodological pluralism. Variability both the substantial contest of elements of identity and their definitions warrants the use of comparative historical method that allows us to analyze the real social and cultural changes. Scientific novelty. The analysis given in the article demonstrates that social institutions have an impact on the formation of gender identity through gender regimes. It is revealed that the transformation of gender inequality is not an inevitable result of biological differences in gender identities. It is proved that biological difference is used to justify the authorities and legitimate the gender inequality. It is established that the biological difference is used to justify social and political inequality of gender identities. The mechanism of continuous reproduction of gender inequality through the work of gender regimes which legitimate the hierarchy of gender identities is described. Conclusions. Understanding how gender inequalities can serve as a starting point for understanding the causes of all kinds of inequalities. Social institutions such as work, education, family, are, in essence, is not neutral, but genderized and serve the reproduction of gender order a certain socio-cultural context as a standard.

<em>Single strand conformational polymorphism is used to identify specific microorganism from the microbial ecosystem at field level. Here the double strand DNA of each organism is converted to single strand and allowed to run in polyacrylamide gel. SSCP can differentiate small variation within same length DNA of different organism due to the difference in retention time, temperature, ionic strength and electrophorotic mobility of ss DNA. This concept is used in this experiment to identify the inoculated microbial consortium from the field by comparison with microbial consortium and pure culture. Azospirillum (Azospirillum brasilense sp 7) and phosphobacteria (Bacillus megaterium var. phosphaticum) and Pseudomonas<strong> </strong>fluorescens (Pf 1) cultures were used for development of liquid microbial consortium for precision farming system. Inoculated microbes from the field were identified through SSCP –PCR analysis. Appearance of unique domain of V<sub>1</sub> to V<sub>9</sub> region of 16srRNA is universal for all bacteria and archae microbial community. Universal primers were used to amplify the V<sub>1</sub> to V<sub>2</sub> region of 16srRNA gene of pure culture, microbial consortium and soil sample from inoculated field for SSCP gel electrophoresis. This study revealed that similar banding pattern was observed between soil sample from inoculated field, microbial consortiums and pure cultures. This experiment proved that SSCP gel electrophoresis is a powerful technique to find specific microorganism in the field in comparison with its pure culture strains without characterization of microorganism. </em>
Quantitative Prediction of Radon Concentration at Wellhead in Shale Gas Development

Published: August 2016

Summary
Hydraulic fracturing has been applied as an effective method to increase gas production from shale formations; however, this method has also raised concerns about its adverse impacts on environment. For example, in the Marcellus shale formation, some measured radon-gas concentrations exceeded the safe standard. Therefore, it is important to quantitatively evaluate radon concentration from fractured wells. However, existing researches have not successfully conducted a systematic and predictive study on the relationship between shale gas production and radon concentration at the wellhead of a hydraulically fractured well. To address this issue and quantitatively determine the radon concentration, we present the mechanisms of radon-gas generation and releasing, and conducted numerical simulations on its transport process in the subsurface formation system. The concentration of radon in produced gas is related with the original sources where the natural gas is extracted. Radon, generated from the radium alpha decay process, is trapped in pore spaces before the reservoir development. With the fluid flowing through the subsurface network, released radon will move to surface with the produced streams such as natural gas and flowback water. Our study shows that the radon concentration at wellhead could be significant. Influential factors such as natural-fracture-network properties, formation petrophysical parameters, and fracture dimension are investigated with sensitivity studies through numerical simulations. Analysis results suggest that radon wellhead concentration is strongly related with production rate. Thus, careful production design and protection are necessary to reduce radon hazard regarding the public and environmental impact.
Development and Field Application of a Novel Cellulose Fracturing Fluid

Published: August 2016

Abstract
Guar and its derivatives, hydroxyl propyl Guar (HPG), carboxy methyl propyl Guar (CMPG), are currently the major gelling agents used for fracturing. However, there is the problem of insoluble residues in Guar after gel breaks. Such residues cause formation damage and low conductivity. Conventional cellulose fluid has problems such as difficult preparation, low temperature limit and high formation damage. This paper presents a novel cellulose derivative of low molecular weight, instant dissolution and free from residue. The new cellulose has better hydrophilic and thickening properties through chemical modification of its structure. The strong hydrogen bonding in cellulose is reduced by alkalization and etherification of substituent group. The viscosity of the new cellulose at 1% (w/v) is 505 mPa·s while the viscosity of HPG or CMPG is 280~320 mPa·s. Its molecular weight is 6×105, which is 1/4 Guar. An organometallic crosslinker was also developed for the new cellulose. Fluid was crosslinked at pH 5-7. Its upper temperature limit was 158 °C. The viscosity of fluid remained 75 mPa·s for 120 minutes at 170 S-1 while that of broken fluid decreased to 1.76mPa·s. No residue was found after the gel was broken, and its conductivity improved. Formation damage is less than 13% in the core test. The new fluid was tested in 18 wells in the tight gas and oil reservoir in western China. Results showed that the new fluid was easy to prepare and rapidly dissolved with no "fish eye". The crosslink of the fluid can be delayed. It has excellent properties of proppant suspension. Oil production after stimulation using the new fluid increased 2-5 times compared with wells in similar locations. Gas production in multiple wells of the tight gas reservoir increased to 1.78×105m3/d after stimulation with the new fluid, 3.38 times higher than similar groups of wells using Guar as stimulation.

Overcoming Challenges in Fracture Stimulation through Advanced Fracture Diagnostics
Authors: Bhatnagar Ankit 
Published: August 2016

Abstract
Historically, different fracture diagnostic methods have been used for hydraulic fracturing treatments to obtain estimates of reservoir characteristics, fracture design parameters, and treatment progress. However, the advent of horizontal drilling techniques and expanded interest in unconventional reservoirs has increased the challenges to overcome to achieve a successful hydraulic fracturing treatment. This paper details advancement made to conventional methods of fracture diagnostics to meet these emerging challenges.
A comprehensive study was conducted on the latest advancements in different diagnostic techniques. Several published case histories were studied where these techniques were adapted and modified from their conventional form. The effectiveness of the advanced techniques in terms of providing additional information was analyzed. A comparative review of the diagnostic methods was performed to determine individual limitations and to identify fit-for-application scenarios. An attempt was made to classify and categorize them according to the ease of application and usefulness for treatment design and analysis.
This study suggests that proper planning, deployment, execution, and analysis of the techniques are essential to helping prevent erroneous conclusions about the treatment and job design. When conducted in unconventional reservoirs, conventional pressure diagnostic methods, as a result of the underlying assumptions of rock properties and fracture geometry, can be interpreted inaccurately. Use of high-fidelity forward models for the inversion of data acquired through these methods can lead to better understanding and help mitigate incorrect interpretation of the results. Similarly, fracture injection-falloff analysis combined with microseismic monitoring and distributed temperature and acoustic (DTS/DAS) data can provide deeper insight into the treatment, particularly for horizontal wells with simultaneously propagating multiple transverse fractures. Thus, a synergistic combination of different diagnostic techniques leads to more effective treatment designs and should be preferred if economically justified.
The current work provides information on advanced fracture diagnostic methods and is useful for determining suitable diagnostic techniques for designing hydraulic fracture treatments.
Acid Fracturing Carbonate-Rich Shale: A Feasibility Investigation of Eagle Ford Formation
Authors: Cash Rachael , Zhu Ding , Hill A. D. 
Published: August 2016

Abstract
Due to the high calcite content of the Eagle Ford Shale (&gt;70%), the formation is a possible candidate for acid fracturing. Similar to hydraulic fracturing, acid fracturing injects pad fluids at a pressure greater than the fracture pressure to initialize fracture, and then inject acids to further propagate fractures and to etch the created fracture face with chemical reactions. In this study, twelve Eagle Ford Shale outcrop samples, four from each zone B, C and D, are used to determine the effect of surface etching pattern, acid concentration, calcite content, and Brinell Hardness on created acid fracture conductivity. The resultant surface etching volume is determined by a pre- and post-surface profilometer scan to calculate the changes in surface profile. Calcite content is determined by X-Ray Diffraction analyses. Conductivity tests are performed on the samples up to a closure stress of 4000 psi, as integrity permits. Based on the results obtained from this study, acid fracturing the Eagle Ford Shale could provide optimistic impact on production. Acid fracturing treatments in high calcite containing zones of the Eagle Ford Shale are expected to result in an increase in productivity. For the Eagle Ford Shale, the surface etching patterns that may provide sustained conductivity are channeling and roughness. A direct correlation is shown between calcite content of the shale and resultant surface etching volume. Furthermore, the higher the calcite content of the samples, the more likely the etching pattern is channeling or surface roughness. Brinell Hardness tests are completed on Eagle Ford samples, showing that, on average, the higher the Brinell Hardness number, the better the resulting surface etching pattern and sustained acid fracture conductivity.
Assessment of Potential Fault Activation in Tarim Basin During Hydraulic Fracturing Operations by Using Rigorous Simulation of Coupled Flow and Geomechanics
Authors: Park Jaeyoung , Kim Jihoon , Zhu Ding 
Published: August 2016

AbstractWe numerically investigate a potential fault activation in Tarim Basin, west China, during hydraulic fracturing operations, by considering rigorous coupled flow and geomechanics. In this study, we find that the fault can be activated by water injection, when it is nearly critically stressed, being sensitive to small changes in stress. Lower cohesion, lower frictional angle, and higher injection rate can activate the fault more easily. Interestingly, the fault becomes activated away from the hydraulic fracture, before the injected water reaches the fault plane. Then, when the hydraulic fracture meets the fault plane, the injected water changes the effective stress of the fault significantly, causing large shear failure. We also calculate the magnitudes of the seismic moment, which are low, because only limited areas of the fault plane are failed. Thus, from this preliminary numerical study of Tarim Basin, we can possibly consider the fault activation as a reservoir stimulation technique for the Tarim Basin field.
