Synthesis of Antioxidant Peptides from Melinjo (Gnetum gnemon) Seed Protein Isolated Using Sol-Gel Immobilized Alcalase

The synthetic of antioxidant peptides from melinjo ( Gnetum gnemon ) seed protein isolated using sol-gel immobilized alcalase was studied, a commercial alcalase was physically entrapped in sol-gel matrices system. Characteristics of protein hydrolyzed were evaluated by the degree of hydrolysis obtained (DH) and the peptide profile by FPLC and SDS-PAGE. The antioxidant activity of protein hydrolyzed was determined using ABTS cation, DPPH, and superoxide radical scavenging assays. The DH values increased very quickly during the second hour followed by a slow increase up to 12 hours. Melinjo seed protein isolated was hydrolyzed about 23% of degree hydrolysis at 50°C after 2 hours of incubation. Similar results were also obtained by FPLC and SDS-PAGE, the peptide profile indicated the sol-gel immobilized alcalase was produced of peptides with low molecular weight from melinjo seed protein isolated. Immobilized alcalase preserved the initial activity over 4 cycles of repeated use in a routine reaction. The ABTS assay, the hydrolysate presented a more than 5 times greater activity than non-hydrolyzed melinjo seed protein isolated. It's confirming the potential use of sol-gel immobilized alcalase in synthetic antioxidant peptides from melinjo seed protein isolated.
Deformation and Cracking Mechanism in CrN/TiN Multilayer Coatings

In this study, the effects of the microstructural properties on the deformation and damage mechanism of CrN/TiN multilayer coatings deposited on Custom 450 steel using the unbalanced reactive magnetron sputtering PVD process were studied. All coatings were fabricated with an overall thickness of 1.5 µm, but different bilayer periods (Λ). Structural and mechanical properties of coatings were investigated by XRD analysis and nanoindentation experiment, respectively. Indentation tests at three loads of 100, 300, and 450 mN were performed on the coatings’ surface and then, cross-sections of fractured imprints were analyzed with SEM and TEM. Measuring the length of the cracks induced by indentation loads and analyzing the load-displacement curves, apparent fracture energy values of multilayer coatings were calculated. We observed that multilayer systems with bilayer periods of 4.5–15 nm possess superlattice structure, which also results in higher values for Young’s modulus and hardness as well as higher fracture energy. Comparison of cross-sectional SEM and TEM observations showed that coatings with smaller bilayer periods tend to deform by shear sliding mechanism due to the existence of the long-grown columns, while short dispersed grains—growing in the coatings with a larger bilayer period—led to deformation via local grain boundary sliding and grain rotation.
A bio-economic analysis of long term changes in the production of French fishing fleets operating in the Bay of Biscay

Selective fishing pressure on more highly valued marine living resources is one of the key factors proposed to explain changes occurring in fish communities and associated landings of commercial fisheries. The aim of this paper is to establish the nature of changes in the landings of French fishing fleets operating in the Bay of Biscay in the period 1973-2002, and whether these changes could be related to the relative economic attractiveness of different fish species. The analysis focuses on trends observed in the landings of all commercial fish species over the last three decades. It is based on data of annual quantities landed and ex-vessel prices compiled from official French landings records, and on bio-geographical descriptors of these species derived from published data. Using simple index numbers and multivariate analysis, we examined changes in total landings in terms of their volume and value, as well as changes in their composition. We show that the composition of landings significantly changed over the study period, with an increase in the proportion of pelagic species, of lower economic value. The average ex-vessel price of production by the fleets tended to decrease from the late 1980s; partly due to a cross-species drop in prices, occurring mainly after 1993, but also to the increased proportion of low-priced species in the landings. This caused a significant drop in the total gross value of production in the second half of the study period.

CHELONOLOGICAL STUDIES OF L.I. KHOSATZKY WITH HIS ANNOTATED BIBLIOGRAPHY ON TURTLES

This paper presents a review of the chelonological research of L.I. Khosatzky (1913–1992), a well-known Soviet zoologist-herpetologist and paleontologist from Leningrad (now Saint Petersburg). It provides an annotated bibliography of his 115 publications on turtles. Khosatzky’s turtle research was devoted to the origin of turtles, systematics, phylogeny and biogeography of fossil and recent turtles, biomechanics, morphology and evolution of the turtle shell, and the ecological physiology of turtles. Khosatzky supervised numerous student works (course projects, graduate and candidate theses) on different aspects of turtle biology, the results of which were only partially published. Some of Khosatzky’s students became well-known specialists on turtles.
NANO-TO-MACROSCALE MODELING OF PHOTONICS THERMAL TRANSPORT

There has been a recent upsurge in the study of nanophotonics, photonics materials, ultra-fast nonlinear photonics and plasmonics. These include research involving nanoscale waveguides, photonic wire lasers, microdisk laser and others. Low-dimensional photonic structures are utilized together with low dimensional electronic structures to achieve simultaneous quantum manipulation of the electron and photon systems. The development of noninvasive in vivo diagnosis of human tissue, such as confocal microscopy and fluorescence spectroscopy, also has been at the high interests of many biomedical researchers. The use of nanoparticles for the imaging, targeting or ablation of specific cell types, tissues, tumors or organs became an exciting new field of research for the medical and scientific communities. Metal nanoshells can be designed and fabricated to absorb or scatter light in the near infrared where human tissue is minimally absorptive. Upon absorption of infrared radiation, nanoshells will provide intense local heating to their surroundings. Recent developments in nanoshells leading to powerful new application in biomedicine, for example in vivo cancer treatment solution, have shown its prospective results for future use. The purpose of this lecture is to review the modeling of the physical processes in relation to photonics thermal transport from nano to macro length scales. The integration of the different methods of analysis applied to nano-to-macro length scales and derived from different theories of the photonic transport (electromagnetic wave and quantum mechanics) will be discussed.
A statistical study of wave propagation in coronal holes

Aims. To find evidence for propagating magnetoacoustic waves in equatorial and polar coronal hole locations Methods. Using temporal series data from the Coronal Diagnostic Spectrometer (CDS) on SOHO, we study oscillations found in radiant flux and velocity measurements from transition region (O! 629) and coronal lines (Mg" 624, Si" # # 520). We use Fourier techniques to measure phase delays between flux (‘intensity’) oscillations and between velocity oscillations of di! erent transition region‐corona and corona‐corona line pairs. We also measure the phase delays between flux and velocity oscillations (I‐V) in the three spectral lines investigated. Results. We find outwardly propagating slow magnetoacoustic waves in both of the coronal hole regions studied. The propagation speeds are found to be lower than those found in o! -limb locations. We find evidence for a resonant cavity or ‘Doppler’ e! ect, whereby the measured phases are present at fixed integer intervals of f/4 (90 " of phase) and 3f/8 (135 " of phase) instead of the expected interval of f or 360 " . We find, in addition, from the I‐V phases, evidence for standing waves at coronal temperatures in the lines of Mg" 624 and Si" # # 520. Correlations are found between the locations where the phases are measured and localised brightenings in both equatorial and polar coronal holes. This suggests that the slow magnetoacoustic waves are originating preferentially from bright areas within the coronal holes which we take to be the locations of concentrated magnetic field (loops, bright points). Finally, we find evidence that in these bright regions along the slit, the measured phases tend to occur at a spectrum of frequencies, perhaps suggesting the presence of discrete propagating wave packets. Conclusions. We conclude that propagating slow magnetoacoustic waves are present in equatorial and polar coronal hole locations and that they occur preferentially in bright regions that are associated with magnetic field concentrations in the form of loops or bright points. In addition, we conclude that some resonant cavity e! ect is a! ecting the propagating waves, perhaps resulting in the standing waves that are found at coronal temperatures.

There is increased interest in biomass gasification for production of a gas which can substitute for fossil fuel. High system efficiency requires good carbon conversion in the gasifier. When a solid fuel particle is injected into a hot fluidized or fixed bed, the reactivity of the resulting char in gasification reactions (between char carbon and steam and CO2 as well as the inhibiting reactions of product gases H2 and CO) play a significant role in reaching good carbon conversion. In this paper, the gasification reactivity data of biomass chars, as measured in TGA experiments, is used for the determination of kinetic parameters for char carbon gasification reactivity correlations. The complicated ash-carbon interactions during char gasification are currently being studied. Laboratory measured reactivity values from TGA experiments are used in the Carbon Conversion predictor to simulate carbon conversion in a real scale fluidized bed gasifier. The predictor is a relatively simple and transparent tool for the comparison of the gasification reactivity of different fuels in fluidized bed gasification. Also a threezone model for fixed bed gasification has been developed, based on models and parameters from the literature. Simulations with the models against some pilot-scale results show reasonable agreement.
The border effect in agricultural markets between European Union, OECD and LDC countries

This paper uses the border effect estimate from a g ravity model to assess the level of trade integration in agricultural markets between EU, OECD and LDC countries, over the 1995-2000 period. The empirical analysis confirms that using a gravity equation derived from theory, in th e estimation of the border effect, matters. A representative estimate of the b order effect shows that crossing a national border into the EU market induc es a trade-reduction effect by a factor of 13. The border effect increases str ongly on passing from trade between OECD countries to trade between LDCs. In the observed period the access to EU market appears quite stable for trade with other OECD countries, whereas it significantly decreases for trade with L DC countries. Finally, we show that the tariff equivalent implied by the esti mated border effects are not implausible when compared to the actual range of di rect protection measures.
EFFICIENT ROUTE FINDER SYSTEM

The work in this paper is to design and implement a Route Finder System that not only try to minimize the number of re-computations needed for computing shortest route or alternate route from source to destination but also models and process the data automatically upon loading of road network graph into memory of the system. We compared the performances of our Route Finder System with Mumbai navigator [8, 9], and we find that our proposed system has much less space and time complexities as compare to Mumbai navigator. We performed the simulation and experiments by using GeoServer, Java, PostGIS and PostgreSQL database.
Mercury inputs to Great Salt Lake, Utah: Reconnaissance-Phase results

In response to increasing public concern regarding mercury (Hg) cycling in Great Salt Lake (GSL) ecosystem, a series of studies were initiated to differentiate between the mass of Hg from riverine versus atmospheric sources to GSL. Cumulative riverine Hg load to GSL during a 1 year time period (April 1, 2007 to March 31, 2008) was 6 kg, with almost 50% of the cumulative Hg load contributed by outflow from Farmington Bay. Comparison of cumulative annual atmospheric Hg deposition (32 kg) to annual riverine deposition (6 kg) indicates that atmospheric deposition is the dominant input source to GSL. A sediment core collected from the southern arm of GSL was used to reconstruct annual Hg deposition rates over the past ~ 100 years. Unlike most freshwater lakes, small changes in water level in GSL significantly changes the lake surface area available for direct deposition of atmospheric Hg. There is good agreement between lake elevation (and corresponding lake surface area) and Hg deposition rates estimated from the sediment core. Higher lake levels, combined with sediment focusing processes, result in an increase in Hg accumulation rates observed in the sediment core. These same combination of processes are responsible for the lower Hg accumulation rates observed in the sediment core during historic low stands of GSL.
The Strongest Link in a Weak Team?

In this study the performance of players in relegated German football clubs is analysed, in particular the change in their contribution to team production. The players in the data sample differ regarding their outside options. Different career opportunities of players may have two effects when their current team struggles against relegation. First, players with outside options should be less motivated compared to the reference group. Second, risk attitudes of players who lack career opportunities may change. The empirical results show that players with outside options contribute less to the teams overall running distance before they are transferred to league opponents. Players who stayed after relegation with their teams played more incomplete passes, which indicates that they are more willing to take risks. Effort levels of staying players get higher, but leaving players might have superior playing talent. JEL-Codes: Z20, Z22, J24, J63, M51, L83
A second-order Markov-modulated fluid queue with linear service rate

We consider an infinite-capacity second-order fluid queue governed by a continuous-time Markov chain and with linear service rate. The variability of the traffic is modeled by a Brownian motion and a local variance function modulated by the Markov chain and proportional to the fluid level in the queue. The behavior of this second-order fluid-flow model is described by a linear stochastic differential equation, satisfied by the transient queue level. We study the transient level's convergence in distribution under weak assumptions and we obtain an expression for the stationary queue level. For the first-order case, we give a simple expression of all its moments as well as of its Laplace transform. For the second-order model we compute its first two moments.
Integrating the 4 Cs in the Learning of Science and Mathematics

The empirical study focused on the extent to which science and mathematics teachers in secondary (Junior & Senior) schools integrate such learning skills as; critical thinking skill, creative thinking skill, communication skill and collaboration skill in their daily lessons. The study was a descriptive survey and an instrument; a 4Cs questionnaire (4CsQ) designed by the researchers was used for the study. Four research questions however guided the survey. The study showed that science and mathematics teachers’ integration of critical thinking and creative thinking in their lessons are still low while the presence of communication and collaboration skills is heavily obvious. A major recommendation was that it is high time science and mathematics teachers embraced and integrated critical thinking and creative thinking in their lessons as to make the learning of mathematics more meaningful to the students of the present age.
Critical thinking education in the portuguese higher education institutions: a systematic review of educational practices

Critical Thinking (CT) education has been a field of growing concern within the Portuguese Higher Education (HE) context, in an attempt to meet the labour market needs and the most demanding and complex societal challenges. However, there is a lack of systematic literature review studies characterizing the different CT educational practices adopted by faculty teachers. Thus, this review intends to understand to what extent the Portuguese teachers in HE have been developing CT skills and dispositions in their students, in a continuous, explicit and effective way. Following the steps of review methods, 27 empirical studies complying with the inclusion criteria were analysed. Results show that CT educational practices are gradually increasing over the years, but they tend to be developed with an implicit, non-intentional and short-term basis, neglecting the development of CT dispositions in the classroom. Studies from different nature are needed (experimental, longitudinal) in order to assess the permanency or generalization of CT in students. Several difficulties were found and future work should stimulate the discussion on the ways to overcome them, guiding HE teachers and institutions in the development, support and evaluation of CT practices.
Provenance and Drainage Evolution of the Red River Revealed by Pb Isotopic Analysis of Detrital K‐Feldspar

The development of the Red River is closely related to the topographic changes in East Asia, but the evolution of this drainage system remains unclear. We determined Pb isotopic compositions of detrital K‐feldspars from the Yinggehai‐Song Hong Basin to understand the sedimentary provenance and to test models of drainage patterns in East Asia. The Pb isotopic data show that detritus in the northern basin was mainly derived from the Red River system since the late Oligocene, and that the Red River achieved its present state in the late Miocene (~10.5 Ma). The variable provenance over time suggests that the Red River was probably connected to the Middle Yangtze and Mekong Rivers before the Miocene, and lost these headwater areas in the middle and late Miocene, respectively. The drainage reorganization probably occurred in response to rapid surface uplift of eastern Tibetan Plateau.
Predicting remaining life of transmission tower steelwork components

Failures in transmission tower’s components usually result in extended disruption of power supply. Repair is very costly as it involves replacement of the transmission lines’ sections affected. Additionally, it might also entail litigation cost associated with power disruption. Maintenance decisions have to be taken in time to prevent a failure. At present, maintenance decisions are mainly based on expert’s judgement, who perform inspections every 10 to 12 years. On specific sites, tower’s components degrade much faster due to aggressive atmospheric conditions, with corrosion being the primary cause of deterioration. In this context, data indicating health state from an UK utility were used to create a Cox model that relates the time before a failure occurs to climatic and atmospheric conditions highly correlated with corrosion. The paper demonstrates the use of the model for predicting remaining tower life, and highlights how this can feed into maintenance planning.

Employment of Microencapsulated Sertoli Cells as a New Tool to Treat Duchenne Muscular Dystrophy

Duchenne muscular dystrophy (DMD) is a lethal X-linked pathology due to lack of dystrophin and characterized by progressive muscle degeneration, impaired locomotion and premature death. The chronic presence of inflammatory cells, fibrosis and fat deposition are hallmarks of DMD muscle tissue. Many different therapeutic approaches to DMD have been tested, including cell-based and gene-based approaches, exon skipping, induction of expression of the dystrophin paralogue, utrophin, and, most recently the application of the CASPR/Cas9 genome editing system. However, corticosteroid treatment remains the gold standard therapy, even if corticosteroids have shown multiple undesirable side effects. Sertoli cells (SeC) have long been known for their ability to produce immunomodulatory and trophic factors, and have been used in a plethora of experimental models of disease. Recently, microencapsulated porcine SeC (MC-SeC) injected intraperitoneally in dystrophic mice produced morphological and functional benefits in muscles thanks to their release into the circulation of anti-inflammatory factors and heregulin β1, a known inducer of utrophin expression, thus opening a new avenue in the treatment of DMD. In order to stress the potentiality of the use of MC-SeC in the treatment of DMD, here, we examine the principal therapeutic approaches to DMD, and the properties of SeC (either nude or encapsulated into alginate-based microcapsules) and their preclinical and clinical use. Finally, we discuss the potential and future development of this latter approach.
Efficient Multi-Attribute Auctions Considering Supply Disruption

Although supply disruption is ubiquitous because of natural or man-made disasters, many firms still use the price-only reverse auction (only the cost is considered) to make purchase decisions. We first study the suppliers’ equilibrium bidding strategies and the buyer’s expected revenue under the first- and second-price price-only reverse auctions when the suppliers are unreliable and have private information on their costs and disruption probabilities. We show that the two auctions are equivalent and not efficient. Then we propose two easily implementable reverse auctions, namely the first-price and second-price format announced penalty reverse auction (APRA), and show that the “revenue equivalence principle” holds, i.e., the two auctions generate the same ex ante expected profit to the buyer. We further show that the two reverse auctions are efficient and “truth telling” is the suppliers’ dominant strategy in the second-price format APRA. We conduct numerical studies to assess the impacts of some parameters on the bidding strategies, the buyer’s profit and social profit.
