LABOR ADAPTATION OF MIGRANTS IN A MEGALOPOLIS
Authors: Полякова  , Polyakova M. 
Published: November 2013

In Russia the labor migration problem has a number of exceptionally
urgent aspects at which are constantly focused both government bodies
and public organizations. These include legal aspects (both in the legislative
and in the criminal fi elds), cultural aspects (tolerance and interpenetration
of cultures problems) and economic aspects.
The author argues that labor migration is considered as a necessary
precondition for normal functioning of society and helps to allocate
optimally the labor resources and provide for balanced development of
diff erent economic regions. The substantial infl ow of migrants began at
the dawn of the market economy and since then boosts the economic
growth of the capital, and maintains the labor resources supply. Immigration
is one of mechanisms to maintain labor potential at the proper level. The
major shortcomings of external immigration are the result of many gaps
in the legal framework of immigration, ignorance of the local laws, culture
and traditions and lack of legal opportunities to get decent work, lodging
and payment. As a result the growing army of illegal foreign workers
leads to the intercultural and social tension and increase in crime.
The most eff ective way to settle the mentioned problems and to suppress
the illegal immigration, the author argues, — is for the government to
make the legal labor immigration highly attractive for both its own citizens
and immigrants.

Authors: Kaya Hasan , Uçar Mehmet 
Published: November 2013

AbstractIn this study, the effects of thixoforming, both equal channel angular pressing (ECAP) and thixoforming on high cycle fatigue and fatigue surface morphology of AA7075 have been examined. Experiments are carried out with the same sample materials (AA7075) at a constant temperature (483 K) and the ``C'' route for 4 passes at ECAP process. In the process of thixoforming is 20 min at 888 K for waiting and 1 min at 673 K for pressing implemented. 140 MPa, 120 MPa and 100 MPa strength values were used at fatigue tests. The microstructural characterizations of the samples were carried out by using optical microscope (OM), scanning electron microscope (SEM) and transmission electron microscope (TEM). This study is an attempt in detail to transformation fine and spherical grain structure with thixoforming process of minimized grain structure by ECAP. As a result of this study, it was seen that ECAP (1 pass) + semi-solid processing (SSP) applied samples have the highest hardness value (171 HV). When the values that are obtained after fatigue strength analyzed, SSP applied materials' property gave the best results and ECAP (1 pass) + SSP applied samples' results were second. When the both process applied materials' optimum values are investigated, it was observed that ECAP 1 pass + SSP applied material is more appropriate in terms of high hardness and fatigue life.
The fate and behavior of persistent, bioaccumulative, and toxic (PBT) chemicals: examining lead (Pb) as a PBT metal
Authors: Check Larissa , Marteel-Parrish Anne 
Published: November 2013

Abstract
Persistent, bioaccumulative, and toxic (PBT) chemicals are a class of chemicals that resist degradation and persist in the environment for extensive periods. As a result of their persistence, when these chemicals are consumed, they bioaccumulate in the fat tissues, bones, and brain of organisms. Lead (Pb) is a PBT metal with the ability to bind irreversibly to neurons and to mimic natural minerals like calcium and zinc. The aim of this review is to examine the unique properties of a PBT, like Pb, as well as the analytic methods of detecting and characterizing PBTs. This review offers sections that explore Pb’s persistence in the environment, bioaccumulation in fish and birds, and toxic characteristics in the human body. It further examines how Pb’s effects on transcription factors could explain the observed Pb lines in Pb-poisoned individuals. This review also evaluates the relationship between the properties of persistence and bioaccumulation as a means to determine whether or not they are interconnected, interdependent, or independent of one another.

Published: November 2013

BACKGROUND AND OBJECTIVES:There is growing evidence of pubertal maturation occurring at earlier ages, with many studies based on cross-sectional observations. This study examined age at onset of breast development (thelarche), and the impact of BMI and race/ethnicity, in the 3 puberty study sites of the Breast Cancer and the Environment Research Program, a prospective cohort of &gt;1200 girls.METHODS:Girls, 6 to 8 years at enrollment, were followed longitudinally at regular intervals from 2004 to 2011 in 3 geographic areas: the San Francisco Bay Area, Greater Cincinnati, and New York City. Sexual maturity assessment using Tanner staging was conducted by using standardized observation and palpation methods by trained and certified staff. Kaplan-Meier analyses were used to describe age at onset of breast maturation by covariates.RESULTS:The age at onset of breast stage 2 varied by race/ethnicity, BMI at baseline, and site. Median age at onset of breast stage 2 was 8.8, 9.3, 9.7, and 9.7 years for African American, Hispanic, white non-Hispanic, and Asian participants, respectively. Girls with greater BMI reached breast stage 2 at younger ages. Age-specific and standardized prevalence of breast maturation was contrasted to observations in 2 large cross-sectional studies conducted 10 to 20 years earlier (Pediatric Research in Office Settings and National Health and Nutrition Examination Survey III) and found to have occurred earlier among white, non-Hispanic, but not African American girls.CONCLUSIONS:We observed the onset of thelarche at younger ages than previously documented, with important differences associated with race/ethnicity and BMI, confirming and extending patterns seen previously. These findings are consistent with temporal changes in BMI.
Strength Training and Physical Activity in Boys: a Randomized Trial
Authors: Meinhardt Udo , Witassek Fabienne , Petrò Renato , Fritz Chris , Eiholzer Urs 
Published: November 2013

BACKGROUND:
In developed societies levels of daily physical activity (PA) among school-age children are decreasing. This implies risk factors for cardiovascular and metabolic diseases. Specific strategies to improve levels of PA are needed. In prepubertal boys there is evidence that strength training increases spontaneous PA outside of training.

METHODS:
A total of 102 schoolchildren (age 10–14 years) in Switzerland were randomly assigned to physical education classes or to participate twice weekly at a guided strength training program for 19 weeks. Spontaneous PA energy expenditure (PAEE; 3axial accelerometry for 7 days), leg and arm strength, and body composition (dual energy radiograph absorptiometry) were measured at baseline, after 19 weeks of training intervention, and after 3 months of washout.

RESULTS:
There were no significant differences between the groups at baseline. In the intervention group, PAEE increased by 10% from baseline to end of training in boys (P = .02), but not in girls. Leg and arm strength were increased owing to training intervention in both boys and girls. All other variables were unchanged. Baseline PAEE was significantly negatively correlated with changes of PAEE.

CONCLUSIONS:
Targeted strength training significantly increases daily spontaneous PA behavior in boys. The less active children showed the greatest increase in spontaneous PAEE. Girls showed a similar increase in strength, but not in spontaneous PAEE. This may be explained by their earlier pubertal development. Strength training may be a promising strategy in schools to counteract decreasing levels of PA.
Best Practice of Using Empirical Methods for Production Forecast and EUR Estimation in Tight/Shale Gas Reservoirs
Authors: Yu Shaoyong 
Published: November 2013

Abstract
Since 2008, a number of new empirical methods have been introduced to the petroleum industry, specifically for gas wells in tight and shale reservoirs. Among them, Valko’s Stretch Exponential Production Decline (SEPD) and Duong’s Rate Decline for Fractured Dominated Reservoir are two most mentioned methods by industry experts. These two methods are claimed to be accurate in both tight and shale gas wells. However, since the reservoir rock permeability in those reservoirs ranges from 0.1 to 0.0001 mD in tight gas to less than 0.0001 mD in shale gas, are these two empirical methods still applicable in all ranges of permeability?
This paper presents the results of an evaluation study by applying these two empirical methods to tight and shale gas wells under a wide range of permeability generated based on both actual and synthetic production data. The key findings and recommended improvements resulted from the study are: Both SEPD and Duong’s Rate-Decline Methods are not applicable to tight gas reservoirs with a permeability ranging from 0.1 to 0.001mD. Duong’s Rate Decline Method will significantly over-estimate EUR whereas SEPD will most likely mismatch the production history as well as yielding a lower EUR while using its Recovery Potential Curve to find parameters.A Modified SEPD Method (YM-SEPD) developed by the author is a much easier and versatile method to use, and most importantly it will yield a more reliable production forecast and EUR estimation.With respect to reservoirs with rock permeability less than 0.01mD, a more rigorous step-by-step work flow using Duong’s Method has been proposed. Moreover, for tight gas reservoirs Duong’s Method can only be used for production forecast during early years, prior to pseudo-steady state (PSS) flow.Hundreds of horizontal wells including both oil and gas wells, from various formations (Cadomin, Montney, Notikewin, Cardium, etc. in Canada) and under different hydraulic fracturing conditions, have been analyzed using these three different methods. Results indicate that the new YM-SEPD Method will yield a more reliable EUR as well as production forecast in comparison with other two methods, especially when there is only less than 2~3 years of production history.For wells having less than 2 years of production history, the YM-SEPD Method will also be able to yield a reasonable prediction by coupling with Duong’s Decline Method
Effects of Thermally-Induced Secondary Cracks on Hydraulic Fracture Geometry
Authors: Tran David , Settari Antonin , Nghiem Long 
Published: November 2013

Abstract
The aim of this paper is to investigate the fracture aperture behavior when secondary cracks occur on the main fracture surface. This phenomenon has not been analyzed in the literature. The investigation shows that the aperture profile of a hydraulic fracture with secondary cracks is no longer a smooth elliptical shape as it used to be when there is no secondary crack, but an irregular shape containing discontinuities (also called jumps). The jump keeps on growing with time when the secondary crack propagates into the formation. The investigation also reveals that the aperture profile of the hydraulic fracture with secondary cracks can be larger or smaller than the one without secondary cracks depending primarily on following factors: permeable (leakoff) or non-permeable (no leakoff) media, locations of secondary cracks and pressurization on the secondary crack surfaces. With the existence of secondary cracks, the location of the maximum fracture aperture is no longer at the centre of the fracture. The study has led to two main conclusions: (i) The effects of secondary cracks on the hydraulic fracture geometry emphasize the important role of geomechanics when simulating a hydraulic fracturing problem. Without considering geomechanics, the jumps in the aperture profile can never been seen; (ii) Abnormal changes in the profile of the main hydraulic fracture with secondary cracks can strongly influence the fracturing stimulation process.
Integration of Nonempirical Shale Permeability Model in a Dual-Continuum Reservoir Simulator
Authors: Singh Harpreet , Azom Prince N. 
Published: November 2013

Abstract
Physics of fluid flow in shale reservoirs cannot be predicted from standard flow and mass transfer models due to presence of nanopores (1-100s of nanometer) in shales. Recently, few models have been developed to account for Slip-flow and Knudsen diffusion due to nanopores in apparent permeability. The limitation with all of these models is that they employ use of some form of empirical coefficient and its value form the basis of accuracy of their models. Additionally, to date, there is no reliable empirical data available for shales due to complexity of the system, i.e., different organic materials and mineral types as well as different gas components in gas shales.
In this paper a new analytical model for permeability of an ultra-tight porous media, consisting of tortuous micro/nano-pores, which is free of any empirical coefficients is incorporated in a dual-continuum reservoir simulator. We use an implicit compositional single phase dual-continuum reservoir simulator capable of modeling gas recovery from naturally fractured, or fissure rich hydraulically fractured, tight to ultra-tight reservoir.
A field scale case study is used to validate the accuracy of the nonempirical permeability model by comparing our predicted results with the results reported by other empirical models. The simulation results obtained with nonempirical permeability model closely match the simulation results reported by other authors with their case study. The nonempirical model shows that the pore-surface roughness and mineralogy has negligible influence on gas flow rate in the complete range of reservoir operating conditions. Finally, apparent permeability for ultratight reservoir (r &lt; 100 nm) is a dynamic parameter and should be adjusted with other reservoir conditions, specifically, reservoir pressure. The model is valid throughout the operating conditions of a reservoir i.e. from the beginning of production until the limit of economic production.
Modeling and Prediction of Cone Rotary Speed of Roller Cone Bits
Authors: Wu A. , Hareland G. , Lei L. , Lin Y. , Yang Y. 
Published: November 2013

Abstract
In this paper, moment of momentum theorem is introduced and used to model the ratio of the rotary speed of cone to the bit. The ratio model has been integrated in a ROP simulator and the simulator can predict the ratio of both tricone and monocone bits. A series of tests measuring the ratio of a 517 IADC roller cone bit has been done. These tests were done with three types of rocks, different weight on bit (WOB) and revolution per minute (RPM). Comparisons between the predictions with the simulator and experimental results are carried out. It shows that the prediction accuracy of the tricone bit is close to 90% and that there is also a good prediction accuracy to the ratio of a monocone bit. The modeling of the ratio of rotary speed of the cone to the bit has improved the accuracy of the ROP simulator, which plays an important role in drilling optimization. Integration of the cone ratio into the modeling increases the overall bit design capabilities to a higher level by using simulators for drill bit performance analysis.
