Abstract:

The effect of high hydrostatic pressure (HHP) on the extraction of flavonoids components (chrysin and galangin) of propolis was studied. The experimental results showed that HHP did not modify their molecular structure. The extraction yields of flavonoids compounds by HHP for 1min were even higher than those obtained with extraction at room temperature (ERT) for 7 days. These excellent results showed a bright prospect for extraction of flavonoids components from propolis.

Abstract:

Educators are often in a position to affect student decisions to work during the school term. This study reviews and summarizes the literature on the effect that employment during high school has on academic achievement. The available evidence suggests that part-time jobs for high school students are beneficial as long as the number of hours worked per week stays under 20.

Abstract:

Recently, several researchers have succeeded in producing expectation–driven cycles by balancing the tension between the wealth effect and the substitution effect stemming from the higher expected future productivity. Especially, seminal research by Christiano et al. (“Monetary Policy and Stock Market Boom–Bust Cycles,” mimeo, Northwestern University, 2007), explains “stock market boom–bust cycles,” characterized by increases in consumption, labor inputs, investment, and stock prices relating to high expected future technology levels. We, however, show that such expectation–driven cycles are difficult to generate based on “growth expectation,” which reflects expectations of higher productivity growth rates.

Abstract:

This note presents an optimal design method to enhance image quality in optical image stabilization (OIS) systems. First of all, performance limitations of conventional methods are shown and secondly, a new design framework based on convex optimization is proposed. The resulting controller essentially stabilizes the closed loop systems because the proposed method is derived from Lyapunov stability. From the test results, it is confirmed that this method reduces the effect of hand vibrations and makes images sharp. Additionally, it is shown that the proposed method is also effective in robot vision and recognition rate of deep neural network (DNN) based traffic signs and pedestrians detection in automotive applications. This note has three main contributions. First, performance limitations of the conventional method are shown. Second, from the relation between sensitivity and complementary sensitivity functions, an indirect design method for performance improvement is proposed, and finally, stability guaranteed optimal design is proposed. Unlike conventional methods, the proposed method does not require addition filters to suppress resonances of the plant and this note highlights phases of the closed loop systems on removing external vibrations.

Abstract:

Recent high profile breaches of regulation by prominent UK financial institutions suggest that self-regulation is ineffective. Intuitively, regulatory breaches should result in a tarnished reputation, but that conjecture is unsubstantiated. With objective measurement of reputation, we demonstrate that reputational damage is not a significant deterrent against regulatory breaches. Imposing regulatory fines is also no deterrent. We speculate that customers are prepared to tolerate large regulatory breaches: retail customers provided they are not affected personally, and corporate customers as long as investments do not devalue. Regulation has not previously been linked to reputation, and this result is significant because it adds to the argument that external regulation remains necessary. Note is also made of recent unsuccessful initiatives on self-regulation.

Abstract:

This study aims at exploring the effects of note-taking strategy on passage listening performance of college students and its implications for listening teaching. For this purpose, the author carried out a study for 15 weeks in Inner Mongolia University for Nationalities. The subjects are divided into experimental class and control class. The teaching method used in the experimental class focuses on incorporating the note-taking strategy training into listening courses and the teaching method used in the control class follows the normal one without the training process of note-taking strategy. The instruments include the pre-test, the post-test, pre-questionnaire and post-questionnaire, and the data collected from the study are analyzed through SPSS17.0. The major findings show note-taking strategy has a positive effect on college students’ passage listening comprehension. After a period of note-taking training, students’ comprehensive competence in listening has improved to some extent. 2) Taking notes as much as possible is not an efficient way to get high-quality notes. The number of questions answerable from the notes is proved closely correlated with achievement of listening comprehension. The other three indices of the total number of notes, the content words notes and the notations have no significance with subjects’ quality of answer.

"High-pressure and high-temperature sintering of nanostructured bulk NiAl materials." Journal of Materials Research 24, no. 6 (June 2009): 2089–96. http://dx.doi.org/10.1557/jmr.2009.0227.

Full text

Abstract:

Nanostructured bulk NiAl materials were prepared at high pressure and temperature (0–5.0 GPa and 600–1500 °C, respectively). The sintered samples were characterized by x-ray diffraction, scanning electron microscope, density, and indentation hardness measurements. The results show that NiAl nanoparticles may have a compressed surface shell, which may be the reason why NiAl nanomaterials were difficult to densify sintering using conventional methods and why high-pressure sintering was an effective approach. We also observed that B2-structured NiAl could undergo a temperature-dependent phase transition and could be transformed into Al0.9Ni4.22 below 1000 °C for the first time. It is interesting to note that Vickers hardness decreased as grain size decreased below ∼30 nm, indicating that the inverse Hall-Petch effect may be observed in nano-polycrystalline NiAl (n-NiAl) samples. Moreover, a tentative interpretation was developed for high-pressure nanosintering, based on the shell-core model of nanoparticles.

Full text

Abstract:

We take another look at the equations behind the description of light bending in a Universe with a cosmological constant. We show that even within the impact parameter entering into the photon's differential equation, and which is defined here with exclusive reference to the beam of light as it bends around the central mass, lies the contribution of the cosmological constant. The latter is shown to enter in a novel way into the equation. When the latter is solved our approach implies, beyond the first two orders in the mass-term and the lowest-order in the cosmological constant, a slightly different expression for the bending angle from what is previously found in the literature.

Abstract:

Selection can produce lines of animals which diverge widely for a range of characters, so that the genetic relations among these and other traits can be investigated. Results are reported on chemical analysis of whole body composition of 10-week-old mice from replicated lines selected high or low for either amount of lean, proportion of fat, or food intake corrected for body weight. There were over two-fold differences in proportion of fat in lines so selected for fat, whereas those selected for total lean showed little difference in composition. Lines selected for high food intake were no fatter than those selected for low food intake. It is confirmed that dry matter proportion is an accurate predictor of fat proportion.

Full text

Abstract:

Mid-Pregnancy nutrition has been shown to have both positive and negative effects on lamb birth weight in primiparous Scottish Blackface ewes. The direction of the effect depends on the level of body condition at mating, being negative in ewes in high body condition (Russel, Foot, White and Davies, 1981). In the same study, it was argued that the effect in younger ewes could be due to their greater sensitivity to both under- and over-nutrition during the earlier to mid stages of their first pregnancy than is evident in older ewes. Russel et al. (1981) also suggested that the level of mid-pregnancy nutrition is likely to have effects on other aspects of production such as embryonic loss, foetal mortality and even ewe mortality.

Abstract:

We compare the seller's expected revenue in asymmetric second-price auctions with the benchmark case where all bidders have the average distribution. We show that with two bidders, asymmetry has a negative effect on revenue. However, for n > 2 bidders there is no clear observation we can make. We prove that in the case of weak asymmetry, sellers prefer asymmetry over low valuations and symmetry over high valuations. In addition, we show that a good approximation for the expected revenue in the case of weak asymmetry can be obtained by calculating the revenue of the symmetric auction with identical distributions equal to the geometric or arithmetic average.

Abstract:

Benhabib and Farmer show that in a laissez-faire one-sector real business cycle model under aggregate increasing returns, under sufficiently high degrees of productive externality, the demand-side effect in the labor market triggered by agents' expectations about the economy's future outweighs the supply-side effect, making agents' expectations become self-fulfilling. This paper analytically demonstrates that the conduct of monetary policy under nominal gross domestic product (GDP) targeting reinforces the supply-side effect in the labor market, thereby making belief-driven aggregate fluctuations more difficult to occur. This reinforcement effect on labor supply is absent under nominal consumption targeting and inflation targeting. Hence, under these two monetary regimes, the necessary and sufficient conditions for the economy to display equilibrium indeterminacy and sunspot fluctuations are identical to those in Benhabib and Farmer's laissez-faire economy. The results are robust to an endogenous growth extension of the model, implying that targeting the nominal GDP growth rate is more desirable than targeting the nominal consumption growth rate or the inflation rate in terms of macroeconomic stability.

Abstract:

I study the relative academic performance of students tracked or randomly assigned to South African university dormitories. Tracking reduces low-scoring students' GPAs and has little effect on high-scoring students, leading to lower and more dispersed GPAs. I also directly estimate peer effects using random variation in peer groups across dormitories. Living with higher-scoring peers raises students' GPAs, particularly for low-scoring students, and peer effects are stronger between socially proximate students. This shows that much of the treatment effect of tracking is attributable to peer effects. These results present a cautionary note about sorting students into academically homogeneous classrooms or neighborhoods. (JEL I23, I24, I28, O15, Z13)

Abstract:

Optical microcavities have been widely used in nonlinear optics, quantum optics, and laser technologies. Here we demonstrate the self-injection locking of a distributed feedback diode laser using home-made high-finesse Fabry-Perot microcavity. The Fabry-Perot microcavity is fabricated from an x-cut lithium niobate crystal with highly reflective coatings. Frequency pulling effect can be observed for a successful locking, and results in a single-longitudinal mode lasing with narrow linewidth. The lasing wavelength and output power are found robust to the laser-diode current and temperature variations, in comparison to the free-running case. We further characterize the laser linewidth with beat note measurement with a high-performance external cavity diode laser, with beat-note linewidth of 601.85 kHz. This results shows a new method for laser frequency stabilization in a simple setup, and may find applications in telecommunication and spectroscopy.

Full text

Abstract:

Distinctive stimuli are better recognized than typical stimuli in many domains (e.g., faces, words). Distinctiveness predicts the point of recognition of a melody (Bailes, 2010), and the recognition of unique tones within a melody (Vuvan, Podolak, & Schmuckler, 2014), yet no studies have examined the role of distinctiveness in recognizing whole melodies. We composed a set of novel melodies according to rules that should result in these being perceived as more or less distinctive. Using computational analysis and human ratings by a group of 36 pilot testers, we established a final stimulus set of 96 novel melodies (48 eightnote, 48 sixteen-note), half of which were high and half low in distinctiveness. A separate group of 26 participants completed a recognition test using this stimulus set. Using linear mixed-effects modeling, we found that greater pitch and interval range, wider intervals, varied contour, and ambiguous tonality within a Western diatonic framework predicted human perception of distinctiveness. However, only a wider modal (most frequent) interval predicted correct recognition. Distinctiveness improved recognition performance in both stimulus lengths; however, a significant advantage was only shown for sixteen-note melodies. Thus, the distinctiveness effect as observed across domains generalizes to the recognition of longer, whole melodies.

Abstract:

We clarify the different effects of elementary and higher education on human capital accumulation and inequality. The productivity of elementary education plays a significant role in the widening of inequality regardless of the existence of multiple steady states. When the productivity of elementary education is low, the poor cannot afford higher education in the long run because the demand for education by the rich makes the price of education too high for the poor. However, the effect of its productivity on the attainable education level is ambiguous. A rise in the productivity of higher education always increases the education level.

Abstract:

Possible global climate change caused by increased 'greenhouse effect' continues to be a matter of international public concern. In particular, a warmer climate is expected to cause increased melting of the Greenland ice sheet, and a rise in world sea level. The Greenland ice sheet is therefore a potential hazard for low-Iying countries. Climate warming may be apparent first, and with greatest magnitude, at high latitudes so that increased melting of the Greenland ice sheet could give early warning of global climate change. For these reasons, GGU and foreign organisations are studying Greenland glaciers in connection with the 'greenhouse effect' (Fig. 1). The present review updates the note by Braithwaite (1990).

Abstract:

Two experiments were conducted to determine whether molasses might exert effects on serum lipoproteins. In experiment 1, 24 rats were divided into two groups and fed diets containing liquid molasses from sugar beet or sucrose (7.71 g of molasses dry matter or sucrose per kg of diet). The second experiment included four groups of rats (n = 12/group) and was conducted in a bifactorial design, with the factors being molasses (non-supplementation vs. supplementation of 77.1 g of molasses dry matter per kg of diet at the expense of sucrose) and dietary cholesterol (0 vs. 5 g/kg diet). In experiment 1, the ratio of low-density lipoprotein (LDL) to high-density lipoprotein (HDL) cholesterol concentration tended to be lower in rats fed the molasses diet than in rats fed the control diet (p < 0.15). In experiment 2, rats fed the molasses diet had higher concentrations of HDL cholesterol (+ 26%) than control rats fed diets without molasses (p < 0.05). This effect was independent of the dietary cholesterol concentration. Concentrations of cholesterol in LDL, very low-density lipoprotein (VLDL), and liver as well as concentrations of triacylglycerols in plasma and liver remained unaffected by molasses in both experiments. In conclusion, the results of this study suggest that supplementation of molasses is effective at raising HDL cholesterol levels in rats.

Abstract:

The development of the electrical power networks to very high voltage (V.H.V) reveals problems involved in the high electric fields; it is essential to consider it in the design of installations in order to avoid or to mitigate some problematic or dangerous effects. Among the most important harmful effects, we can note the "radio interference disturbances". The principal aim of this paper is the use of a simulation programme using an analytical method based on the theory of propagation modes, made by one of the authors, for determination and calculation of the exact profile of disturbance field of actual high voltage lines (220 kV) and in project (400 kV) in dry weather and under rain. Specific software called "effect corona" was developed for this purpose.

Supercritical carbon dioxide (SC-CO2) was used for anhydrous ovine milk fat (AMF) fractionation. Two different fractions were obtained: a low molecular weight triacylglycerol (TAG), named fraction E, and a high molecular weight TAG, termed fraction R. Fractionation was performed at different pressure and temperature values. The effect of these parameters on the chemical composition of the two fractions were analysed in relation to the original AMF. Among the searched conditions, 250 bar and 40°C gave the best fractionation results.

However, the fabrication of thin films with pure DNA has not been sufficiently studied. We characterize the uniformity of thin films from aqueous salmon DNA solutions mixed with ethanol, methanol, isopropanol, and acetone. Measurements of thickness and macroscopic uniformity are made via a focused-beam ellipsometer. We discuss important parameters for optimum uniformity and note what the effects of solvent modifications are. We find that methanol- and ethanol-added solutions provide optimal fabrication methods, which more consistently produce high degrees of uniformity with film thickness ranging from 20 to 200 nm adjusted by DNA concentration and the physical parameters of spin-coating methods.

Abstract:

This multiple baseline study investigated the effectiveness of history strategy instruction emphasizing the linkage of knowledge in teaching junior high students with behavior disorders. The intervention included 24 students and 3 teachers across three classes for 3–6 weeks. The strategy included a scripted curriculum involving brisk student-teacher interchanges; student note taking and constructing of timelines and vocabulary definitions; and reciprocal questioning, using a carefully selected history textbook. Results indicate that the history strategy was effective; students in each class showed immediate and educationally significant improvement compared with baseline instruction that employed traditional history instruction.

Abstract:

Value investing is one of the most popular stock-picking strategies employed in financial markets. We investigate its effectiveness in the United Arab Emirates. We examine the performance of 124 firms in the period from January 2004 to March 2019. We analyze portfolios from one-way sorts on several well-known valuation ratios: earnings-to-price, book-to-market, EBITDA-to-EV, and dividend yield. Our results demonstrate a powerful value effect in the UAE stock markets. The long-short strategies based on valuation ratios display high raw and risk-adjusted returns. Our results are robust to many considerations.

Abstract:

Seventeen Brahman steers were removed from pasture and fed a high grain diet for 8 weeks prior to slaughter. Carotenoid concentrations were determined in samples of serum and subcutaneous fat obtained either from live animals or at slaughter. At slaughter carcass fat colour was assessed according to AUS-MEAT specification. The concentrations of G-carotene in the serum of these animals fell rapidly (over 60%, P lt; 0.001) in the first 2 weeks on the grain diet and then plateaued. There was no change in either the concentrations of carotenoids in subcutaneous fat or in fat colour of these cattle during the whole period of grain feeding. The overall average liveweight gain was 0.59 kg/day. Failure to observe changes in concentrations of carotenoids was unexpected, and may be partly due to the fact that these cattle did not settle to the trial conditions in the feedlot, as indicated by the significantly higher cortisol concentration in their serum compared with the initial slaughter group. The implications of the outcome of this study are discussed.

Abstract:

Purpose Although online brand communities (OBCs) are extensively demonstrated to be an important social media tool in building brand equity, they may have backfire effects under certain conditions. Drawing from the self–brand connection theory, the purpose of this study is to investigate the effect of group heterogeneity on brand commitment. The mediation effect of self–brand connection and moderation effect of brand symbolism has also been examined. Design/methodology/approach Data were collected using a survey of 498 users from a range of OBCs. Hierarchical regression and bootstrapping method were used to test the research model. Findings The findings indicate that group heterogeneity negatively affects brand commitment in which self–brand connection plays a role of mediation. Further, the negative effect is more pronounced for high-symbolic brands than low-symbolic ones. Practical implications Brand managers are advised to note the dark side of OBCs in general and alleviate the adverse effects of group heterogeneity in particular, especially for high-symbolic brands. Originality/value Previous research pays little attention to the adverse effect of OBCs. This study enriches the literature by revealing that the backfire effect of OBCs arises when users become heterogeneous and uncovering in what situations the negative effect is stronger.

Full text

Abstract:

Ti-based intermetallic compounds are characterized by low machinability, therefore, to obtain accurate dimensions and shape of the surface grinding and Wire EDM are used. The unique properties of NiTi intermetallic alloys are largely influenced by structural phase transformations and variations in microhardness caused by processing accompanied by thermal phenomena. Having an understanding of the physics of the process, it is possible to counteract negative effects, which helps to preserve thermomechanical properties of the final NiTi products. Accumulation of knowledge about the quality of processing with various abrasive tools is part of the larger research presented in this article. Samples of titanium nickelide with a temperature Af=+25 0С were abraded with ordinary and high porosity SiC wheels. The article studied phase transformations using X-ray diffraction analysis and microhardness. The experimental data were processed using mathematical statistics. X-ray diffraction patterns and microhardness analysis showed that a significant effect on the structural transformation and corresponding increase in microhardness is exerted by grinding with green SiC wheels with normal porosity caused by an increased thermal effect on the surface. Simultaneously, the impact of Wire EDM process on microhardness in preparing workpieces for grinding was evaluated. It was established that grinding of Ti-based intermetallic compounds with memory effect should be performed by SiC wheels with an open structure of high porosity.

Abstract:

The aim of this work was to study silo raw milk (SRM) compositional parameters that affect the heat stability of whole milk powder (WMP). Seasonal changes of heat stability from SRM and WMP were also characterised. Silo raw milk samples and the corresponding WMP samples were collected twice a month from a local factory from April 2000 to April 2001. Silo raw milk heat coagulation time (HCT), urea and lactose concentrations were found to contribute to milk powder HCT statistical model (R2 = 0.72). High HCT values during summer and low ones during spring were detected for both SRM and WMP samples. Heat coagulation time values of SRM were always higher than those measured in their powders, due to the effects of processing conditions on heat stability

Abstract:

We investigate a high-order homogenization (HOH) algorithm for periodic multi-layered stacks. The mathematical tool of choice is a transfer matrix method. Expressions for effective permeability, permittivity and magnetoelectric coupling are explored by frequency power expansions. On the physical side, this HOH uncovers a magnetoelectric coupling effect (odd-order approximation) and artificial magnetism (even-order approximation) in moderate contrast photonic crystals. Comparing the effective parameters' expressions of a stack with three layers against that of a stack with two layers, we note that the magnetoelectric coupling effect vanishes while the artificial magnetism can still be achieved in a centre-symmetric periodic structure. Furthermore, we numerically check the effective parameters through the dispersion law and transmission property of a stack with two dielectric layers against that of an effective bianisotropic medium: they are in good agreement throughout the low-frequency (acoustic) band until the first stop band, where the analyticity of the logarithm function of the transfer matrix ( ) breaks down.

Full text

Abstract:

Abstract The high-frequency shape of the earthquake spectrum strongly influences the amplitude of the peak ground acceleration and of the response spectrum at frequencies of 10 Hz and greater. A key parameter for the description of high-frequency ground motions is “kappa,” which is the decay slope of the Fourier spectrum of acceleration at near-source distances (Anderson and Hough, 1984; note Anderson and Hough originally referred to this parameter as kappa (0)). Kappa may be attributed to site effects (fmax; Hanks, 1982), source processes (Papageorgiou and Aki, 1983), or both. Seismographic data place weak but significant constraints on kappa values. On average, there is no resolved kappa effect on spectra recorded at rock sites in eastern Canada, in the frequency range f ≦ 30 Hz. Four firm-soil sites in southwestern Ontario also show no kappa effect. An implied upper bound for kappa is 0.004 (or lower bound of 30 Hz for fmax). By contrast, source spectra from earthquakes in the Cascadia region, recorded on hard-rock sites in southwestern British Columbia (B.C.), appear to be well described by a kappa of 0.011 ± 0.002. The B.C. spectra are thus intermediate to the eastern case, with zero apparent kappa, and the typical California case, for which kappa is about 0.04.

Abstract:

This note investigates the possibility of profit raising entry in network industries where firms follow Corporate Social Responsibility (CSR) behaviours, showing the interaction between the network and CSR features. In particular, for high levels of the network effect, an incumbent’s profits raising entry effect occurs. The latter result is at odds with the conventional wisdom and shows another channel the preceding literature has so far not explored for the possibility of a profit raising entry.

Full text

Abstract:

An attempt is made to understand the isotope effects measured by Zhao et al. in LaSrCuO in terms of a previous theory for high Tc superconductors, a theory based on pair coupling by soft lattice modes. In the theory, the lattice elastic energy originating with the ion-electron correlation limits the gap. Here we note that this elastic energy does not depend directly on the ionic masses. However, the mechanical lattice parameters in the neighborhood of a structural phase transition are so sensitive that the free energy of oscillation and, hence, the masses are able to have an influence. Minimization of the free energy of the solid with respect to the lattice deformation leads to an equation of state, as basis for finding the effects of the ionic mass changes. With the measured isotope effects at several values of doping as input to the calculation, we obtain, as output, very plausible results for the Fermi energy, the lattice softening, and the electron-phonon coupling constant.

Abstract:

Metallic nanostructures (MNs) and metal-organic frameworks (MOFs) play a pivotal role by articulating their significance in high-performance supercapacitors along with conducting polymers (CPs). The interaction and synergistic pseudocapacitive effect of MNs with CPs have contributed to enhance the specific capacitance and cyclic stability. Among various conjugated heterocyclic CPs, polypyrrole (PPy) (prevalently knows as “synthetic metal”) is exclusively studied because of its excellent physicochemical properties, ease of preparation, flexibility in surface modifications, and unique molecular structure–property relationships. Numerous researchers attempted to improve the low electronic conductivity of MNs and MOFs, by incorporating conducting PPy and/or used decoration strategy. This was succeeded by fine-tuning this objective, which managed to get outstanding supercapacitive performances. This brief technical note epitomizes various PPy-based metallic hybrid materials with different nano-architectures, emphasizing its technical implications in fabricating high-performance electrode material for supercapacitor applications.

Abstract:

The present study aimed to ascertain whether the automaticity of a learned-cognitive process persisted after lengthy and complete cessation of practice. The musical Stroop paradigm offers the opportunity to test this specific question by evaluating the automaticity of note naming, the flexibility in manipulating practice of which is much greater than that of other cognitive automatisms like reading. Participants who previously attained a high level of musical expertise and ceased all musical practice for at least 3 years exhibited a musical Stroop effect, which attests to the automaticity of note naming. The musical Stroop effect was still observed in a subset of participants who completely ceased musical practice for more than 10 years. Our results suggest that the absence of practice, even over a very long period of time, does not eliminate the automaticity of cognitive processes.

Abstract:

The effect of high temperature deformation on the low thermal expansion property of Fe -29 Ni -17 Co alloy was investigated in the compressive temperature range of 900~1300°C at a strain rate range of 25 ~ 0.01 sec. -1. The thermal expansion coefficient (α30~400) generally increased with increasing compressive temperature. In particular, α30~400 increased remarkably as the strain rate decreased at temperatures above 1100°C. Note, however, that α30~400 at low compressive temperatures (900°C and 1000°C) increased abnormally at high strain rates. Based on the investigation of various possibilities of change in low thermal expansion behavior, the experimental results indicated that both the appearance of the α phase and evolution of grain size due to hot compression clearly influenced the low thermal expansion behavior of this invar-type alloy. The correlation between the microstructural cause and invar phenomena and theoretical explanation for the low thermal expansion behavior of Fe -29% Ni -17% Co were also suggested.
