使用済み自動車からの板ガラスリサイクルの環境性および事業採算性評価

Objective. Recycling of glass from end-of-life vehicles (ELV) has been of interest since the enforcement of Law on Recycling of End-of-Life-Vehicles. The objective of this work is to investigate the environmental and economic aspects of the recycling system of glass sheets from ELV. Life cycle inventory analysis was conducted to analyze the reduction potential of CO2 emissions by recycling the grass sheets from ELV. Cash flow analysis (CFA) was applied to the recycling system, in which internal rate of return, IRR, was used as an index of the economic feasibility. Sensitivity analyses were conducted to investigate the effect of the transport distances of collected glass sheets from ELV on CO2 emissions and IRR, respectively.Results and Discussion. It was found that the reduction potential of CO2 emissions by recycling the grass sheets from ELV was 17 kg-CO2/ELV, which was mainly attributable to the reduction of CO2 emissions in production of glass sheet by the use of glass cullet and by avoidance of the treatment of automobile shredder residue (ASR). From the results of MFA by the authors reported in the previous paper, this result would be valid as long as the amount of glass cullet recovered from ELV would not exceed to 124 thousand t/year. CFA showed that the amount of inverse onerous contract, loading ratio of truck transport and collection area of glass sheets from ELV had significant effect on IRR. Conclusions. This work has proved that there is a certain reduction potential of CO2 emissions by recycling glass from ELV. The economical feasibility is significantly dependent on the amount of inverse onerous contract, loading ratio of truck transport, collection area, and prices of recovered materials, so it is recommended that stakeholders should discuss how to manage the recycling glass from ELV. This case study also shows integration of LCA, MFA and CFA is very effective when we assess environmental and economic aspects of recycling materials from end-of-life products.

Influence of muscle contraction and intensity of stimulation on the cutaneous silent period

We evaluated the influence of stimulus intensity (SI) and the amount of voluntary muscle contraction (VMC) on parameters of the cutaneous silent period (CSP). The CSP was measured in 15 healthy subjects at 20%, 40%, and 60% of maximal VMC and after an electric stimulus of 10, 15, and 20 times the sensory threshold. Average EMG amplitudes prior to stimulus and during the CSP increased with the amount of VMC. The CSP duration increased, and suppression index decreased, with increasing SI. The CSP onset and end latencies seemed to shorten and prolong, respectively, with the increasing SI, although this was not statistically significant. Considering the more meaningful temporal parameters of the CSP and the suppression index, it is not necessary to control the VMC, but it is advisable to control the SI.

Three-dimensional analysis of the tooth movement and arch dimension changes in Class I malocclusions treated with first premolar extractions: A guideline for virtual treatment planning

Our objective was to analyze patterns of tooth movement and changes of arch dimension by superimposing 3-dimensional (3D) virtual models. The sample consisted of 24 Korean adults with Class I malocclusion and minimal crowding, treated by first premolar extractions, sliding mechanics (0.022-in MBT brackets [3M Unitek, Monrovia, Calif] with 0.019 × 0.025-in stainless steel wire) and moderate anchorage. The 3D virtual maxillary casts at pretreatment and posttreatment were superimposed with the best-fit method. Linear and angular variables were measured with 3Txer program (Orapix, Seoul, Korea). Wilcoxon signed rank and Mann-Whitney tests were used for statistical analysis. There was no significant difference in the individual tooth movement between the right and left sides (P > 0.05). For the movement of each tooth, the maxillary central incisors (U1), lateral incisors (U2), and canines (U3) were significantly inclined lingually, extruded, and moved posteriorly and laterally. The maxillary second premolar (U5), first molar (U6), and second molar (U7) had significant mesial inward rotation, anterior movement, and contracted toward the midsagittal plane. The ratio of anteroposterior movement between the maxillary anterior and posterior teeth was 5:1. The amounts of contraction in U5, U6, and U7 were 1.4, 1.3, and 1.2 mm, respectively. When the amount of change between the adjacent teeth were compared, the linguoversion in U1 was significantly greater than that of U2. U3 and U5 showed significant opposite movements in all variables. There were differences only in angulation and vertical displacement between U6 and U7. Superimposition of 3D virtual models could be a guideline for precise virtual treatment planning.

Retreating Melaleuca swamp forests in Kakadu National Park: Evidence of synergistic effects of climate change and past feral buffalo impacts

Abstract Melaleuca swamp forests form a fringe around seasonally inundated freshwater flood plains of Kakadu National Park (KNP). Previous studies based on the analysis of aerial photography reported an increase in woody plant cover on these flood plains, apparently associated with changed fire regimes, increased rainfall and possibly increased atmospheric CO2. In opposition to this woody vegetation encroachment past high densities of feral buffalo in the 1960 to mid 1980s changed the hydrology of the KNP flood plains, allowing increased penetration of saltwater causing extensive death of Melaleuca forests. Climate change has increased sea levels and there is concern that this will threaten the freshwater ecosystems of KNP. We hypothesized that Melaleuca forests that were previously impacted by high densities of feral buffalo have continued to decline because of salinization driven by sea level rise. We examined this hypothesis by overlaying georeferenced aerial photography taken in 1964, 1984 and 2004 in a geographic information environment, and then constructing generalized linear fixed effects and mixed effects models to rank the statistical strength of different drivers of Melaleuca forest contraction. We found that there has been a 5% overall contraction of Melaleuca forests over the last 50 years on our study sites, although the amount of contraction varied both geographically and temporally. The amount of Melaleuca forest contraction was greatest during the 1984–2004 interval, when buffalo densities were low. Contraction was greatest on the Melaleuca forest edges, at low‐lying sites, and where high densities of buffalo were apparent in 1964. These results suggest the enduring legacy effect of past buffalo damage will amplify the effects of sea level rise on the flood plains of KNP.

Magnitude of global contraction on Mars from analysis of surface faults: Implications for martian thermal history

Faults provide a record of a planet’s crustal stress state and interior dynamics, including volumetric changes related to long-term cooling. Previous work has suggested that Mars experienced a pulse of large-scale global contraction during Hesperian time. Here we evaluate the evidence for martian global contraction using a recent compilation of thrust faults. Fault-related strains were calculated for wrinkle ridges and lobate scarps to provide lower and upper bounds, respectively, on the magnitude of global contraction from contractional structures observed on the surface of Mars. During the hypothesized pulse of global contraction, contractional strain of −0.007% to −0.13% is indicated by the structures, corresponding to decreases in planetary radius of 112 m to 2.24 km, respectively. By contrast, consideration of all recognized thrust faults regardless of age produces a globally averaged contractional strain of −0.011% to −0.22%, corresponding to a radius decrease of 188 m to 3.77 km since the Early Noachian. The amount of global contraction predicted by thermal models is larger than what is recorded by the faults at the surface, paralleling similar studies for Mercury and the Moon, which suggests that observations of fault populations at the surface may provide tighter bounds on planetary thermal evolution than models alone.

금리와 건설수주간 회귀분석을 통한 건설경제 예측기법

금리의 하락은 건설투자를 유도할 수 있다. 즉 금리는 건설 경기에 영향을 주는 요소 중의 하나이다. 본 연구의 목적은 연도별 건설수주액과 금리와의 관계를 분석하고 이를 통해 향후 건설경제를 예측하는 정량적인 모델을 제시하는 것이다. 이를 위하여 1991년부터 2009년까지 19년간의 자료를 바탕으로 금리와 건설수주액 상호간의 관계를 분석하고 금리와 건설수주액을 각각 종속변수와 독립변수로 하는 회귀식을 유도하여 향후 건설경기를 예측하는 방법을 제시한다. 결과적으로 수주총액, 건축, 민간 부문 등의 수주액은 3년 뒤의 금리와, 주택부문은 2년뒤의 금리와의 상관계수가 모두 0.85이상으로 매우 밀접한 관계가 있는 것으로 나타났다. 회귀분석을 통해 수주총액, 건축, 주택, 민간 부문에 대한 수주액을 예측하는 회귀식을 도출하여 적용한 결과 수주총액, 건축, 민간의 경우 2011년까지 수주액이 감소하고 2012년에는 증가하는 것으로 분석되었으며, 주택부문의 경우 2010년까지 수주액이 감소하고 2011년부터는 증가하는 것으로 분석되었다. Rising interest rates positively affect investment in construction, while falling interest rates affect it negatively. In other words, the interest rate is one of the most critical factors affecting the construction sector. The purpose of this research is to analyze the relationship between the annual interest rate and construction contracts, and to present a model for quantitatively forecasting the economic performance of the construction sector. Based on the statistical data of interest rate changes for 19 years (from 1991 to 2009), this research induces an equation through regression analysis that incorporates interest rate and construction contract amounts as independent and dependent variables, respectively. The result of the analysis shows that, in the building and private sector, the interest rates are closely related to, with a correlation coefficient as high as 0.85. It was also indicated that the contract amounts of private and building sectors may increase quite rapidly in 2012.

DARK MATTER CONTRACTION AND THE STELLAR CONTENT OF MASSIVE EARLY-TYPE GALAXIES: DISFAVORING “LIGHT” INITIAL MASS FUNCTIONS

We use stellar dynamics, strong lensing, stellar population synthesis models, and weak lensing shear measurements to constrain the dark matter (DM) profile and stellar mass in a sample of 53 massive early-type galaxies. We explore three DM halo models (unperturbed Navarro Frenk & White [NFW] halos and the adiabatic contraction models of Blumenthal and Gnedin) and impose a model for the relationship between the stellar and virial mass (i.e., a relationship for the star-formation efficiency as a function of halo mass). We show that, given our model assumptions, the data clearly prefer a Salpeter-like initial mass function (IMF) over a lighter IMF (e.g., Chabrier or Kroupa), irrespective of the choice of DM halo. In addition, we find that the data prefer at most a moderate amount of adiabatic contraction (Blumenthal adiabatic contraction is strongly disfavored) and are only consistent with no adiabatic contraction (i.e., a NFW halo) if a mass-dependent IMF is assumed, in the sense of a more massive normalization of the IMF for more massive halos.

Decomposing the Term Structure of Swap Rates in Light of the Financial Crisis

Interest rate swaps are one of the most important financial instruments in the world. The BIS reports that the notional amount of these contracts outstanding as of June 2009 was $342 trillion, with a gross market value of $13.9 trillion. Not only are these contracts important hedging instruments, but the term structure of swap rates has become a benchmark in its own right in that it is often used as reference curve in derivative models. Clearly, understanding the determinants of the term structure of swap rates is important. Under specific assumptions regarding the nature of default and counterparty credit risk, Duffie and Singleton (1997) show that the swap and the LIBOR curve are the same. However, as the swap market has matured, ISDA introduced standards of credit enhancement, the most important being posting of collateral and frequent marking to market. Due to these enhancements, the swap curve now deviates enormously from the LIBOR curve. Recent studies of swap spreads take the absence of counter party credit risk for granted and focus on the credit risk inherent in the LIBOR itself, or more precisely in the refreshed LIBOR index published by the British Bankers Association, together with flight to quality discounts, sovereign risk premia associated with governments, and costly posting of collateral. Studies along these lines are well summarized by Johannes and Sundaresan (2006) and Feldhuetter and Lando (2008), and the references therein. The financial crisis has disrupted historical relationships between FRAs, swaps and their standard spot LIBOR replications. Further, large basis spreads have appeared for exchanging floating payments with different tenors that traditional models cannot explain. The impact of establishing the appropriate discounting factors for the simplest of collateralized derivatives is now profound. For example, our analysis shows that pricing one-year swaps using appropriate LIBOR or Treasury rates results, in each case, in persistent errors, the magnitude of which, subsequent to the financial crisis, is often as large as 100 basis points. Many of the existing studies on swaps cannot explain this phenomenon. Our paper contributes to the literature by carefully investigating the determinants of swap rates along the maturity spectrum. We accomplish this by jointly modeling not only the term structure of Treasury, LIBOR and swap rates, but also the Overnight Indexed Swap (OIS) curve. Using information from the OIS market is key to our analysis, since in contrast to LIBOR and Treasury rates, OIS rates are viewed as being a closer indicator of true riskless rates among private counterparties that transact in collateralized markets. All data are obtained from Bloomberg, Datastream and the FRED database at the St. Louis Fed. A preliminary analysis shows that the term structure of swap rates is indeed sensitive to the term structure of LIBOR-OIS spreads, the term structure of OIS-Treasury spreads and the term structure obtained from prices of bonds of AA rated financial firms, with the degree of dependence varying systematically with maturity. Our goal is to develop arbitrage-free models of swap and OIS rates that reflect these empirical features. Our study also examines how the relative importance of each swap rate component has changed since the crisis. The results will cast insight into the appropriate discount rates to use when pricing collateralized interest rate sensitive derivatives, and will directly contribute to the ongoing debate on how best to regulate over-the-counter contracts.

Tissue Contraction Caused by Radiofrequency and Microwave Ablation: A Laboratory Study in Liver and Lung

To determine the amount of tissue contraction during radiofrequency (RF) and microwave ablation.Markers were inserted into explanted bovine liver and lung 10 mm (inner), 20 mm (middle; not used in lung), and 30 mm (peripheral) diametrically around an ablation applicator. Aside from unablated controls, RF and microwave ablations 25-30 mm in diameter were then created and sectioned to measure the distance between markers (n = 12, liver RF; n = 8, other). Total contraction was calculated by subtracting postablation measurements from controls at each position. Relative contraction was calculated by subtracting the nearest more central measurement. Sample water content was measured to determine the relationship between dehydration and relative contraction. A mixed-effects model tested for differences in diameters, total and relative contraction, and water content with energy, tissue, and marker position as independent variables.Total contractions at the inner, middle, and peripheral positions in liver were 2.9 mm (31%), 4.8 mm (24%), and 4.5 mm (15%) for RF and 3.6 mm (38%), 6.6 mm (33%), and 9.0 mm (30%) for microwave, respectively. Significantly more contraction was noted in lung (P < .001): 5.1 mm (55%) and 14.2 mm (49%) for RF and 4.8 mm (52%) and 13.7 mm (47%) for microwave at the inner and peripheral positions, respectively. Microwaves produced more contraction than RF in liver (P < .05) but not in lung. A positive correlation between dehydration and relative contraction was observed in all cases.Ablation-induced tissue contraction is substantial and influenced by dehydration. Contraction should be considered when testing devices and computer models or comparing pre- and postablation images.

Quantification of Human Abdominal Tissue Tightening and Contraction After Component Treatments With 1064-nm/1320-nm Laser-Assisted Lipolysis: Clinical Implications

Internal lipoplasty (iLAL) represents an evolving procedure that depends on delivery of sufficient and controlled thermal energy for lipolysis and collagen denaturation. Of the two outcomes, the particular advantage of iLAL may exist in its capability to selectively denature, remodel, and contract collagen and elastin fibers for eventual skin contraction. Despite the practice of sound laser principles and clinical outcomes, laser lipolysis has not been readily accepted because of its yet unproven advantages over other liposuction devices. This limited clinical research study on the lower abdomen of three female subjects provides objective data by Vectra 3D analysis (Canfield Scientific, Fairfield, New Jersey) of significant skin contraction (average, 9.1% at three months; average, 7.6% at six months) as a consequence of the application of sequential wavelengths of 8 W 1064 nm/8 W 1320 nm within the shallow but not the deep subdermal layers. The application of sustained and confluent thermal injury within the targeted 4 x 10-cm rectangular panel (zone 5) was continually monitored by an internal temperature-sensing cannula (45-47 degrees C) and by an external surface temperature-sensing infrared camera, recording surface skin temperatures to 40-42 degrees C threshold levels. Minimal skin contraction was measured at three months in panels that were treated by tumescence (1.1%, zone 1) and cannulation (1.5%, zone 2). Of interest, the slight increase in skin contraction in zones treated by volume reduction after liposuction (3.6%, zone 3) or deep lasing plus liposuction (3.6%, zone 4) may be due more to skin accommodation than active skin contraction. The second highest amount of skin contraction was observed in zone 6 (4.2%), which was treated by shallow lasing, liposuction, and deep lasing. Further quantitative clinical studies will be needed to validate these findings.

Linear Measurement of Cell Contraction in a Capillary Collagen Gel System

Three-dimensional collagen gel contraction is the standard assay utilized for functionally quantifying a variety of cell types, in particular smooth muscle cells (SMCs) and myofibroblasts. Here, we have developed a method to effectively reduce the three-dimensional parameters of the standard collagen gel into a single, linear measurement. Cell/collagen suspensions that are cast into glass capillary tubes provide several advantages over the well plate format, such as eliminating the need for digital imaging equipment and software to quantify the amount of cellular contraction. In addition, capillary tube gels require significantly fewer cells and far less reagents than standard methods.

Space–time coordination dynamics in basketball: Part 2. The interaction between the two teams

In this article, we examine the space–time coordination dynamics of two basketball teams during competition. We identified six game sequences at random, from which the movement data of each player were obtained for analysis of team behaviours in both the longitudinal (basket-to-basket) and lateral (side-to-side) directions. The central position of a team was measured using its spatial (geometric) centre and dispersion using a stretch index, obtained from the mean distance of team members from the spatial centre. Relative-phase analysis of the spatial centres demonstrated in-phase stabilities in both the longitudinal and lateral directions, with more stability in the longitudinal than lateral direction. As anticipated, this finding is consistent with the results of an analysis of individual playing dyads (see companion article, this issue), as well as the more general principle of complex systems conforming to similar descriptions at different levels of analysis. Phase relations for the stretch index demonstrated in-phase attraction in the longitudinal direction and no attraction to any values in the lateral direction. Finally, the difference between the two stretch indexes at any instant showed phase transitions between two stable patterns when the difference was represented in binary form. This result is attributed to the reciprocity between teams in their amounts of expansion and contraction when possession of the ball is won and lost.

Dimensional changes of starch microcellular foam during the exchange of water with ethanol and subsequent drying

Starch microcellular foams (SMCF) containing pores in the micron size range may be prepared by pore-preserving drying processes, developing highly porous, high specific surface area materials useful for applications such as opacifying pigments or as adsorbent materials. The objective of this research was to understand how the exchange of water with ethanol, used as a pore preserving step, affected the dimensional properties of the starch material during and after processing. SMCF were prepared from molded aquagels of cooked corn starch that were subjected to ethanol exchanges with different time intervals (6, 12, or 48 hrs) and number of exchanges (1, 2, or 3) and then air dried. To study the transformation of water-swollen starch into precipitated starch foam in ethanol, the volume of the starch material was measured in the wet state after each exchange and after final air drying. As water is replaced by ethanol, the starch material contracts, with the greatest contraction during the first ethanol exchange. The amount of contraction during air drying decreased with decreased starch water content just before air drying, presumably due to less pore collapse of the stiffer cell walls on drying. Interestingly, the minimum density of 0.37 g/cc SMCF was for the 12 hour exchange time, not the longest exchange time. Evidence of a skin-core morphology included SEM images as well as dimensional instability data on dried samples. The results indicate that SMCF of low density with fewer tendencies to deform during drying does not necessarily require extremely long exchange times.

Are variations in length of Y chromosome due to structural changes?

Earlier research on the causes of extreme variation in the length of the Y chromosome has given ambiguous results. The development of the fluorescence technique has made it possible to study this chromosome in more detail. The results reported here indicated that extremely short and extremely long Y chromosomes result from structural changes, not from differences in amount of contraction. It is impossible, without study of further material, to draw conclusions on the clinical characteristics associated with aberrations in the length of this chromosome.

Estimating Project S-Curves Using Polynomial Function and Neural Networks

The S-curve is a graphical representation of a construction project’s cumulative progress from start to finish. While S-curves for project control during construction should be estimated analytically based on a schedule of activity times, empirical estimation methods using various mathematical S-curve formulas have been developed for initial planning at predesign stages, with the mean for past similar projects often used as the basis of prediction. In an attempt to make an improvement, a succinct cubic polynomial function for generalizing S-curves is proposed and a comparison with existing formulas shows its advantages of accuracy and simplicity. Based on an analysis of the attributes and actual progress of 101 projects, four factors, i.e., contract amount, duration, type of work, and location, are then used as the inputs of a model developed for estimating S-curves as represented by the polynomial parameters. For model development, it is proposed to use neural networks for their ability to perform comple...

A novel approach to improve cardiac performance: cardiac myosin activators

Decreased systolic function is a central factor in the pathogenesis of heart failure, yet there are no safe medical therapies to improve cardiac function in patients. Currently available inotropes, such as dobutamine and milrinone, increase cardiac contractility at the expense of increased intracellular concentrations of calcium and cAMP, contributing to increased heart rate, hypotension, arrhythmias, and mortality. These adverse effects are inextricably linked to their inotropic mechanism of action. A new class of pharmacologic agents, cardiac myosin activators, directly targets the kinetics of the myosin head. In vitro studies have demonstrated that these agents increase the rate of effective myosin cross-bridge formation, increasing the duration and amount of myocyte contraction, and inhibit non-productive consumption of ATP, potentially improving myocyte energy utilization, with no effect on intracellular calcium or cAMP. Animal models have shown that this novel mechanism increases the systolic ejection time, resulting in improved stroke volume, fractional shortening, and hemodynamics with no effect on myocardial oxygen demand, culminating in significant increases in cardiac efficiency. A first-in-human study in healthy volunteers with the lead cardiac myosin activator, CK-1827452, as well as preliminary results from a study in patients with stable chronic heart failure, have extended these findings to humans, demonstrating significant increases in systolic ejection time, fractional shortening, stroke volume, and cardiac output. These studies suggest that cardiac myosin activators offer the promise of a safe and effective treatment for heart failure. A program of clinical studies are being planned to test whether CK-1827452 will fulfill that promise.

Supramolecular Interactions in Chitosan Gels

AbstractChitosan gel particles show selective size changes with a large variety of effector compounds. Swelling induced by protonation of the chitosan amino groups is counteracted by non‐covalent cross‐linking with anions, depending on the structure of the acids. Thus, contraction amounts to 30 % with malonic acid, but to &lt;1 % with the homologuous succinic acid, to 60 % with tartaric acid and to 51 % with 2,4‐dinitrophenol. With acetic acid expansion starts at around pH 6, whereas with, for example, hydrochloric acid swelling occurs at around pH 4. All size changes are essentially due to changes in water content. Basic amino acids, such as His, Lys and Arg, induce significantly enhanced expansion only in the presence of other acids as cofactors, therefore performing as logic AND gates. Enantioselective size changes are large with dibenzoyltartaric acid derivatives. Reducing the size of the gel particles allows the speed of size change to increase significantly; a similar sensitivity increase is achieved by the accompanying compartmentalization effect.

Secretaries of Pork? A New Theory of Distributive Public Policy

Scholars have focused attention toward congressional influence over distributive grant allocations, but they have less frequently examined the extent to which administrative agencies play a role in that process. We present a new theory of ideology-contingent executive decision making within a multiple-principals framework to explain the geographic distribution of policy benefits. Our theory is novel in that it locates interbranch ideological conflict and confluence at the center of bureaus’ allocational strategies. Discretionary Department of Labor (DOL) grants and Department of Defense (DOD) contracts from 1991 to 2002 are examined to provide evidence that agencies deliver more grants to senators with proximate ideologies. To measure bureaucratic ideology, we generate comparable ideology estimates for cabinet secretaries, presidents, and members of the U.S. Senate via an item-response model. Our findings suggest that ideological congruence between senators and DOL or DOD is associated with significantly larger amounts of grants or contracts, respectively. These findings are important as they recast our understanding of distributive politics into ideological terms.

Recycled Concrete Aggregate Coefficient of Thermal Expansion

Despite a critical shortage of virgin aggregate, the availability of demolished concrete for use as recycled concrete aggregate (RCA) is increasing. Using this waste concrete as RCA conserves virgin aggregate, reduces the impact on landfills, decreases energy consumption, and can provide cost savings. However, there are still many unanswered questions about the beneficial use of RCA in concrete pavements. This research studied the effect of RCA on the coefficient of thermal expansion (CTE) and its impact on pavement performance. CTE is a key property of concrete and relates to the amount of expansion and contraction caused by changes in temperature. CTE testing was conducted on 16 cores containing various amounts of coarse RCA (0%, 15%, 30%, and 50%) using a simplified methodology. Testing showed that concrete performance improved as the amount of RCA increased. This result was demonstrated by a decrease in CTE; values for the CTE ranged from 7.28 × 10-6/°C for 0% coarse RCA to 4.10 × 10-6/°C for 50% coarse RCA. The variability of the CTE results was also examined to assess whether the RCA content or simplified testing methodology affected the results. Performance of the RCA concrete was simulated by using the Mechanistic–Empirical Pavement Design Guide. Average, minimum, and maximum CTE values for each RCA amount were used to investigate the sensitivity of this important property on pavement roughness, cracking, and faulting. Simulated pavement performance of all the RCA sections improved as the CTE values decreased.
