Abstract:
Abstract Carbon nanotubes are one of the strongest materials of unique mechanical, optical, electrical and electronic properties. Because of that they are mainly used as semiconductor materials constituting the reinforcing phase in composite materials. The paper presents properties of polymer composites reinforced with carbon nanotubes (CNT) containing various mixtures of dispersion. Produced composites featured various content carbon nanotubes: 20%, 30%, 40% i 50%. Macroscopic observations were carried out on ready to check composites, if pores exist in the structure and whether the reinforcement has been distributed in the entire volume. Bending and compressive strengths tests were performed and densities of individual composites were measured to determine the specific strength. Composite materials strengthened with carbon nanotubes feature a very low density and a very good mechanical strength, which makes them a good structural material.

ABSTRACT:Objective:To determine the impact of check size and interstimulus interval (ISI) on neuromagnetic visual cortical responses.Methods:We recorded visual evoked fields to pattern-reversal stimulation with central occlusion in ten subjects. The ~100 ms magnetic activation (P100m) was analyzed by single dipole modeling.Results:With 1 s ISI, P100m strengths increased as check size increased from 15' up to 120' of visual arc, and larger checks elicited less P100m activation. With 120' checks, we found no P100m attenuation as ISI decreased from 4 s to 0.16 s. P100m sources around the calcarine sulcus did not vary with check size or ISI.Conclusions:The magnitude of cortical activation during visual contrast processing is check size-dependent and the 120' checks are optimum for future studies on neuromagnetic visual cortical functions using central-occluded stimulation. The corresponding neuronal activation demonstrated a short refractory period less than 0.16 s. We also found significantly overlapping cortical representation areas for different check sizes or ISIs.

Abstract:
Abstract During the rotary peeling of veneer for plywood or the laminated veneer lumber manufacture, checks are formed in the veneer that are as deep as 70–80% of the veneer thickness. The results of this study show that, during adhesive bond testing, deep lathe checks in birch (Betula pendula Roth.) veneer significantly reduce the shear strength and the percent wood failure of phenol-formaldehyde (PF) – bonded plywood. The results also show that specimens tested with the checks pulled open or closed can fail by different mechanisms. Dried rotary peeled birch veneers were sanded to create uniform surfaces with lathe check depths varying from 30% to 90% of veneer thickness. Then, 7-ply plywood was manufactured with a commercial PF resin. After the preparation of the test specimens, the check depth of each specimen was measured microscopically. Subsequently, bond quality was measured according to EN 314. The results show that veneer checking alone can bring EN 314 specimens to the brink of failure even with an excellent adhesive. These findings stress the importance of measuring the depth of lathe checks and considering the orientations of checks during the testing to get a better understanding of bond quality in veneer-based products.

Abstract:
The peeling of small-diameter rubberwood logs from the current short-rotation practices undoubtedly will produce lower grade veneers compared to the veneers from conventional planting rotation. Hence, this raises the question of the properties of the produced laminated veneer lumber (LVL) from veneers peeled from small-diameter rubberwood logs using the spindleless lathe technology. Different thicknesses of rubberwood veneers was peeled from rubberwood logs with diameter less than 20 cm using a spindleless lathe. Three-layer LVLs were prepared using phenol formaldehyde (PF) adhesive and hot pressed at different temperatures. During the peeling of veneer, lathe checks as deep as 30–60% of the veneer thickness are formed. Owing to deeper lathe check on 3 mm rubberwood veneer, higher pressing temperature significantly increased the gluebond shear strength of the PF-bonded LVL. In addition, lathe check frequency was also shown to influence the bond strength. The presence of higher lathe check frequency on 2 mm veneer increased the wettability, thus facilitating optimum penetration of adhesive for stronger bonding. These findings stress the importance of measuring and considering the lathe check depth and frequency during the lamination process to get a better understanding of bonding quality in veneer-based products.

Abstract Objectives To determine the relative influence of sociodemographic, socioeconomic, psychosocial, and health variables on health service utilization in the last 12 months. Methods Data were analyzed for 1,412 men ≥60 years old from a 2012 nationally representative community-based survey in Jamaica. Associations between six health service utilization variables and several explanatory variables were explored. Logistic regression models were used to identify independent predictors of each utilization measure and determine the strengths of associations. Results More than 75% reported having health visits and blood pressure checks. Blood sugar (69.6%) and cholesterol (63.1%) checks were less common, and having a prostate check (35.1%) was the least utilized service. Adjusted models confirmed that the presence of chronic diseases and health insurance most strongly predicted utilization. A daughter or son as the main source of financial support (vs self) doubled or tripled, respectively, the odds of routine doctors’ visits. Compared with primary or lower education, tertiary education doubled [2.37 (1.12, 4.95)] the odds of a blood pressure check. Regular attendance at club/society/religious organizations’ meetings increased the odds of having a prostate check by 45%. Discussion Although need and financial resources most strongly influenced health service utilization, psychosocial variables may be particularly influential for underutilized services.

Abstract:
When doing mechanical design, in order to ensure proper function of crucial parts, not only should the structure be well-designed, but also should strength and rigidity meet the requirement. However, traditional checking methods contain many procedures and are complicated, which makes mistakes easy to occur; and once it goes wrong in any procedure, the design must be carried out again from the start. So, much time and energy of the designers are wasted on checking, and they can’t focus on the design itself. AutoCAD Mechanical is a version of AutoCAD designed specially for mechanical professionals. It contains all the graphic drawing function of AutoCAD, and with its shaft design function, strength, torsion angle and rigidity checks can be carried out easily. Compared with traditional design method, it has the advantage of simpler operation and full-automatic structuralization. Somehow it is not used by many. Hence, with many years of experiences, the author analyses the design and calculation of shaft parts with AutoCAD Mechanical, in hope to help designers release repeated inefficient work, and raise the quality and efficiency of design. Foreword During mechanical design, in order to ensure proper functions and mechanical properties of parts such as shaft, strength check must be carried out. For crucial parts, rigidity and torsion angle checks are also necessary, to ensure the deformations are within allowable range, so as to make sure that the shaft can bear the loads and work properly. However, strength check requires massive knowledge and procedures, as well as complicated calculations, which makes it easy to go wrong. During the calculation, the values of various coefficients should be considered, and once taken improperly, it may lead to vague calculation results, and then the procedure must be carried out again. Undoubtedly, this method makes design efficiency low, and designers must spend much time and concentrations on repeated work, instead of focusing on renovation. However, checking strength of shaft with AutoCAD Mechanical can make the procedures simple and accurate, and raise the efficiency.

Abstract:
AAC LeRoy (BW1049) is a hollow stemmed, awned, high-yielding Canada Western Red Spring (CWRS) wheat suited to the growing conditions in western Canada. AAC LeRoy was 10% higher yielding than Unity, the highest yielding check in the Central Bread Wheat Cooperative registration trials (2015–2017). Within the same test, AAC LeRoy was 13% higher yielding than Carberry, a popular CWRS wheat variety across the Canadian Prairies. AAC LeRoy matured 2 d earlier than Carberry and 1 d later than Unity, the earliest maturing check suited for eastern prairie growing conditions. AAC LeRoy was 6 cm shorter with better stem strength than Unity. The lodging score for AAC LeRoy was lower than the mean of the checks. The test weight of AAC LeRoy was similar to the mean of the checks. Over the 3 yr of testing (2015–2017), the 1000-kernel weight of AAC LeRoy was higher than all of the checks, with a grain protein content 0.6% units lower than Carberry. AAC LeRoy was rated as moderately resistant to Fusarium head blight (Fusarium graminearum Schwabe), leaf rust (Puccinia triticina Erikss.), stripe rust (Puccinia striiformis Westend.), and stem rust (Puccinia graminis Pers. f. sp. tritici Erikss. & E. Henn), including the Ug99 family of stem rusts. It also had a resistant reaction to loose smut [Ustilago tritici (Pers.) Rostr.] and an intermediately resistant reaction to common bunt [Tilletia caries (DC.) Tul. & C. Tul.]. AAC LeRoy was resistant to orange wheat blossom midge (Sitodiplosis mosellana Géhin). AAC LeRoy was registered under the CWRS market class.

With the emergence of social networks, mining interesting information from the social media datasets becomes a popular research direction. Previous re-searches on social networks, such as POI (point of interest) recommendation, usually ignore the social tie strength between users. If we can further consider the closeness between friends in the analysis, it is possible to improve the results. Therefore, in this paper, we focus on analyzing the social tie strength between users in the location-based social network. The proposed method analyzes the movement of users, the interaction between them and location properties by the spatial-temporal data. Furthermore, we take into account the geographical feature and the influence of check-in times. Finally, the location list for POI recommendation will be constructed accordingly. Experimental results show that the proposed method significantly outperforms the competitor on both the precision and the recall.

Abstract:
This chapter introduces the book’s two central puzzles: what explains Latin America’s obsession with fixing democracy via constituent assemblies, and what explains variations in outcomes of constituent assemblies? It introduces the key argument: power asymmetries between Incumbents and Opposition forces—in the form of variations in the relative strength of the Incumbent vis-à-vis the Opposition, more so than other factors such as economics, ideology, or partisanship—lead to constitutions that offer weaker checks and balances. Power asymmetries, the book argues, influence to some extent the incidence of constitutional change and to a large extent the content of resulting constitutions. The book illustrates these points by examining twenty-four constitutional moments in Latin America since the 1980s, including eleven drafted new constitutions and thirteen aborted constituent assemblies. Finally, this chapter offers a justification for the book’s case selection and explains the research design pursued therein.

Abstract:
Is it possible to develop techniques and mechanisms so that women can get out of a depression without the help of medication, even though they are in a deep state of apathy? It is scientifically proven that moving, eating well, cultivating good relationships and even meditating are actions that help the human being to become fuller and happier. The recipe is easy. There is a step-by-step that, most of the time, provides positive results to those who follow it. But what about when the individual is listless? At that stage of unwillingness, lack of strength and courage to change the stage? He may be fully aware of what he should do, how he should act and how much it would be beneficial for his well-being, yet he still does not find the strength to act. It is a feeling of pain and anguish that does not pass and there is no desire to do anything to pass. Would it be possible to use or create a revolutionary technique or set of techniques, "magical" that help the start of psychological / emotional change, without the aid of drugs? There are numerous studies that demonstrate both the ineffectiveness and the various side effects of antidepressant and psychotropic drugs. To check if there are mechanisms that help individuals to restore mental and emotional health without the aid of allopathy is to find a way out so that less people, in addition to not getting rid of depression, become dependent on the medications they use. Nowadays depression is often diagnosed and treated incorrectly, especially among women – one in seven is medicated. If there are effective mechanisms to change a depressive stage in a natural way, there will be a reduction in the consumption of medications, thus avoiding serious side effects such as dependence, reactions and physical changes such as disorderly weight loss or gain, sexual dysfunction and incapacity to live in society.

Abstract:
This is an advance summary of a forthcoming article in the Oxford Research Encyclopedia of Climate Science. Please check back later for the full article.The concept of statistical downscaling or empirical-statistical downscaling became a distinct and important scientific approach in climate science in recent decades, when the climate change issue and assessment of climate change impact on various social and natural systems have become international challenges. Global climate models are the best tools for estimating future climate conditions. Even if improvements can be made in state-of-the art global climate models, in terms of spatial resolution and their performance in simulation of climate characteristics, they are still skillful only in reproducing large-scale feature of climate variability, such as global mean temperature or various circulation patterns (e.g., the North Atlantic Oscillation). However, these models are not able to provide reliable information on local climate characteristics (mean temperature, total precipitation), especially on extreme weather and climate events. The main reason for this failure is the influence of local geographical features on the local climate, as well as other factors related to surrounding large-scale conditions, the influence of which cannot be correctly taken into consideration by the current dynamical global models.Impact models, such as hydrological and crop models, need high resolution information on various climate parameters on the scale of a river basin or a farm, scales that are not available from the usual global climate models. Downscaling techniques produce regional climate information on finer scale, from global climate change scenarios, based on the assumption that there is a systematic link between the large-scale and local climate. Two types of downscaling approaches are known: a) dynamical downscaling is based on regional climate models nested in a global climate model; and b) statistical downscaling is based on developing statistical relationships between large-scale atmospheric variables (predictors), available from global climate models, and observed local-scale variables of interest (predictands).Various types of empirical-statistical downscaling approaches can be placed approximately in linear and nonlinear groupings. The empirical-statistical downscaling techniques focus more on details related to the nonlinear models—their validation, strengths, and weaknesses—in comparison to linear models or the mixed models combining the linear and nonlinear approaches. Stochastic models can be applied to daily and sub-daily precipitation in Romania, with a comparison to dynamical downscaling. Conditional stochastic models are generally specific for daily or sub-daily precipitation as predictand.A complex validation of the nonlinear statistical downscaling models, selection of the large-scale predictors, model ability to reproduce historical trends, extreme events, and the uncertainty related to future downscaled changes are important issues. A better estimation of the uncertainty related to downscaled climate change projections can be achieved by using ensembles of more global climate models as drivers, including their ability to simulate the input in downscaling models. Comparison between future statistical downscaled climate signals and those derived from dynamical downscaling driven by the same global model, including a complex validation of the regional climate models, gives a measure of the reliability of downscaled regional climate changes.

Abstract:
We introduce the concept of "tragic choices": those that concern our vital and identity experiences. As in the tragedies of classical Greek theater, there are circumstances in which there is no right and wrong, since theses capable of exhibiting arguments of almost equal strength are opposed. This is what happens today due to the contrast between economic and ecological predicaments: there is no optimal choice in this regard, valid always and in any case, that allows us to neglect and forget the other option. This is why, in pragmatic terms, the concept of “a-growth” is useful: we check on a case-by-case basis when economic growth can still be useful, when it should be slowed down and when it needs to be reduced. This approach is part of the research, itself pragmatic, of the "boundaries of the biosphere". These are not rigid limits, but constraints that must be interpreted and adapted, based on the idea of "being happy", where being satisfied means making the biosphere feel good with us inside.

Abstract:
AbstractVarious empirical studies have established the positive relationship between teacher professional community (PC) and participative decision-making (PDM) within schools. Considering that these relationships proved relevant to school improvement in different countries, a comparative approach will allow us to establish whether this positive relationship holds true for a wider range of European countries. This study presents results of this relationship using data from 35,000 secondary teachers in 22 European countries. Taking an exploratory approach, the study investigates the relationship between the presence of PC and the school actors involved in PDM. We are particularly interested in the level of active participation in decision-making by teachers, the school governor or counsellor, and by students, and the relative presence of PC. We find this relationship to be significant and positive, but varying in strength according to the actors involved in decision-making. Furthermore, the relationship is stronger across all countries studied when teachers are significantly involved in decision-making as opposed to when school counsellors or governors are more involved. Regarding student involvement in decision-making, its relationship with PC proved stronger when students could influence school rules or help choose teaching and learning materials. The relationships measured and compared across countries were tested for robustness by applying a test for measurement invariance of the PC latent concept and discussing its implications for the relationships of interest. After other relevant robustness checks, we conclude that, across all European countries studied, there is a positive relationship between PC and PDM in schools, with the involvement of some actors in PDM being more indicative of the presence of PC than the involvement of others.

Abstract:
According to Chesnais (1992), the fluctuation of human populations can be summarized into three broad categories: the pretransitional, transitional, and posttransitional cycles. In the pretransitional period before the Industrial Revolution, population fluctuations appear to reflect natural constraints of the environment. In more recent centuries, there were changes of the vital rates from high fertility-high mortality to low fertility-low mortality, which are referred to as demographic transitions. In this transitional period, because the decline of mortality usually leads that of fertility, fluctuations in the population age structure are a natural consequence of such a transition. After this transitional period, in many developed countries the mortality rate is stabilized, and female fertility becomes a typical family decision. Since family fertility decisions are related to other market institutions, the posttransitional population cycles have close interactions with these institutional elements. Although the population cycles can be separated into the three above-mentioned types, these cyclical movements share one common feature: the Malthusian environmental check always plays a direct or indirect role. In the next few chapters, I will discuss how the environmental checks interact with human decisions and institutions and how these interactions affect the cyclical movement of the population. Thomas Malthus argued that all populations are subject to environmental constraints and that these constraints operate through a variety of checks to population growth. If there are no such checks, we have a stationary branching process as described in chapters 2-6. In that case, the population will converge to a steady state under weak assumptions, and there are fluctuations only in the process of convergence. When there are environmental checks, the strength of the checks determines the speed with which the system tends toward equilibrium; this speed, relative to response lags that are intrinsic to the process, heavily influences the dynamic behavior of the economic-demographic system. When checks are weak, shocked populations tend to converge slowly without overshooting and to move in cycles one generation long (Lee, 1974). If checks arc stronger, overshooting may occur, and longer cycles of periodicity spanning two generations or more are possible, as population size and growth rates oscillate about their equilibrium values.

Abstract:
Recent hurricanes in Gulf of Mexico, most notably Ivan (2004), Katrina & Rita (2005), Ike (2008), were more severe than the local 100 year extremes in the Gulf of Mexico (GoM). As a result API has issued an interim metocean bulletin, API Bulletin 2INT-MET [1]. Concurrently, API also issued API Bulletin 2INT-EX [2] for assessment of existing offshore structures for hurricane conditions. API Bulletin 2INT-EX recommends a robustness check to evaluate floating structure critical components including production and export risers. The robustness check for risers as a minimum should consider the capacity and ductility of the key riser components. This paper investigates the robustness of a steel catenary riser (SCR) suspended from a deepwater tension leg platform (TLP) unit in Central GoM. The robustness assessment is performed for the 1000 year Central GoM hurricane conditions provided in API 2INT-MET. Time domain coupled analysis using the program DeepC is performed to determine the TLP motions and the associated loading on the SCR. SCR strength capacity checks are performed as per the methods outlined in new ISO 13628-12 [3].

Full text
Abstract:
This paper examines the inherent conservatisms of alternative girth weld defect acceptance criteria from the 2007 API 1104 Appendix A, CSA Z662 Appendix K, and the proposed EPRG Tier 2 criteria. The API and CSA codes have the same empirical limit-load criteria, where it has previously been shown that the conservatism on the failure stress is ∼30 to 50 percent compared to pipe test data prior to applying any safety factors. In terms of flaw length, it was found that the API/CSA limit-load equation might allow a flaw of 5% of the pipe circumference, where the properly validated limit-load equation would allow a flaw of 75% of the circumference, i.e., a safety factor of 30 percent on load corresponded to a safety factor of 15 on flaw length for that example case. Similarly there are conservatisms in a proposed EPRG Tier 2 girth weld defect acceptance criterion. This proposed criterion was directly based on curved-wide-plate data to assure that toughness was sufficient to meet limit-load conditions for a curved-wide plate. However, the curved-wide plates are really an intermediate-scale test, and still require proper scaling to pipes of different diameters. The proposed Tier 2 EPRG allowable flaw length is 7T from a large database of curved-wide-plate tests with the a/t value of less than 0.5 (or a < 3mm), and the failure stress being equal to the yield strength of the base metal (also requires the weld metal overmatch the base metal strength, and the Charpy energy at the defect location have a minimum > 30 J and average > 40 J). However, the widths of those curved-wide-plate tests are typically a factor 5 to 12 times less than typical large-diameter pipes. The proper limit-load/fracture mechanics scaling solution would have the flaw length proportioned to the plate width, not the specimen thickness. Additionally, the proper limit-load solution for a pipe in bending gives a much larger tolerable flaw size at the yield stress loading than a plate or pipe under pure tension. Example calculations showed that the EPRG Tier 2 approach is conservative on the flaw lengths by approximately 9 for pure axial tension loading, and between 34 to 79 for a pipe under bending. Suggestions are presented for an improved procedure that accounts for proper limit-load solutions for pipe tests, effects of pipe diameter, effects of internal pressure, and also a much simpler approach to incorporate the material toughness than the 2007 API 1104 Appendix A Option 2 FAD-curve approach. The fracture analyses could evoke SENB, SENT testing, or have relatively simple Charpy test data to assess the transition temperatures to ensure ductile initiation will occur.

Abstract:
The article is devoted to the evaluation of frost resistance of a propylene-ethylene block copolymer used as an insulating material for cable products. The standard method for testing the frost resistance of a polymer material is a drop weight impact test on insulated core samples at low temperatures. To check this parameter at the stage of incoming polymer control, it is proposed to use the method of dynamic mechanical analysis (DMA). As a result of experimental studies by the DMA method, a criterion for evaluating the frost resistance of a block copolymer of propylene with ethylene was established

Abstract:
Abstract Steel Lazy wave risers are being increasingly used for deep water applications due to better strength and fatigue performance in the touchdown zone compared to steel catenary risers. Several parameters govern the design of steel lazy wave risers including the length of the catenary from hang-off to start of buoyancy section and the length of the buoyancy section. In this paper, a parametric study is performed to investigate the trends in strength and fatigue performance of steel lazy wave risers with change in configuration parameters. A normative cost assessment is also performed to show the impact of these design variables on overall cost of the system. Dynamic analysis is performed to check the change in strength and fatigue performance of steel lazy wave risers as the configuration parameters are changed. The results from the parametric study will assist in designing steel lazy wave risers which satisfy the strength and fatigue design criteria.
