Preliminary results for the composition of the leachate from unsaturated tests at 90{degrees}C with spent fuel for 55--134 days with J-13 groundwater are reported. The pH of the leachate solutions was found to be acidic, ranging from 4 to 7. The actinide concentrations were 10{sup 5} greater than those reported for saturated spent fuel tests in which the leachate pH was 8. We also found that most species in the leachate were present as colloids containing both americium and curium. The presence of actinides in a form not currently included in repository radionuclide transport models provides information that can be used in spent fuel reaction modeling, the performance assessment of the repository and the design of the engineering barrier system. This report was prepared as part of the Yucca Mountain Site Characterization Project

There is an increasing demand for scalable deployment of real-time multimedia streaming applications over Internet. In this context, Peer-to-Peer (P2P) networks are playing an important role for supporting robust and large-scale transmission of multimedia content to heterogeneous clients. However, the deployment of real-time video streaming applications over P2P networks arises lot of challenges due to heterogeneity of terminals and access networks, dynamicity of peers, and other problems inherited from IP network. Real-time streaming applications are very sensitive to packet loss, jitter / transmission delay, and available end-to-end bandwidth. These elements have key importance in QoS provisioning and need extra consideration for smooth delivery of video streaming applications over P2P networks. Beside the abovementioned issues, P2P applications lack of awareness in constructing their overlay topologies and do not have any explicit interaction with service and network providers. This situation leads to inefficient utilization of network resources and may cause potential violation of peering agreements between providers. The aim of this thesis is to analyze these issues and to propose an adaptive real-time transport mechanism for QoS provisioning of Scalable Video Coding (SVC) applications over P2P networks. Our contributions in this dissertation are threefold. First, we propose a hybrid overlay organization mechanism allowing intelligent organization of sender peers based on network-awareness, mediaawareness, and quality-awareness. This overlay organization is further used for an appropriate selection of best sender peers, and the efficient switching of peers to ensure a smooth video delivery when any of the sender peers is no more reliable. Second, we propose a packet video scheduling mechanism to assign different parts of the video content to specific peers. Third, we present a service provider driven P2P network framework that enables effective interaction between service / network providers and P2P applications to perform QoS provisioning mechanism for the video streaming.

A gas pipeline through the Caucasus mountains is under construction and includes the excavation of two tunnels through the Kobyla Mountain of the Northern Caucasus. The Blue Stream gas pipeline project from Russia to Turkey is a $3 billion project and is the deepest undersea product pipeline, 396 km long with depths as low as 2,150m in the Black Sea. Initially there were no plans for tunneling until contractors recognized the difficulties of passing over the Caucasus mountains.


Pressure and flow waves measured in the aorta can be decomposed into one foryard and one backward traveling component. In this paper we postulate that the forward and backward waves are not single waveforms. but are themselves composed of individual antegrade and retrograde waves. The antegrade waves include the initial waveforms (produced in the absence of reflection) and those arising from reflections at the aortic valve while the retrograde waves are produced by reflections in the periphery. Modeling the arterial system as an equivalent single tube terminating in a complex load, we derive expressions relating the measured waveforms with the initial waveforms, reflection coefficients, and properties of the arterial system. Results indicate that multiple wave reflection does occur with the waves decreasing in amplitude as reflection continues. In addition, it appears that individual reflections tend to become insignificant before the onset of the next cardiac cycle.


Recently it was realized [1] that linear optics and photo-detectors with feedback can be used for theoretically efficient quantum information processing. The first of three steps toward efficient linear optics quantum computation (eLOQC) was to design a simple non-deterministic gate, which upon post-selection based on a measurement result implements a non-linear phase shift on one mode. Here a computational strategy is given for finding non-deterministic gates for bosonic qubits with helper photons. A more efficient conditional sign flip gate is obtained.


This paper evaluates a Successive Response Surface Method (SRSM) specifically developed for simulation‐based design optimization, e.g. that of explicit nonlinear dynamics in crashworthiness design. Linear response surfaces are constructed in a subregion of the design space using a design of experiments approach with a D‐optimal experimental design. To converge to an optimum, a domain reduction scheme is utilized. The scheme requires only one user‐defined parameter, namely the size of the initial subregion. During optimization, the size of this region is adapted using a move reversal criterion to counter oscillation and a move distance criterion to gauge accuracy. To test its robustness, the results using the method are compared to SQP results of a selection of the well‐known Hock and Schittkowski problems. Although convergence to a small tolerance is slow when compared to SQP, the SRSM method does remarkably well for these sometimes pathological analytical problems. The second test concerns three engineering problems sampled from the nonlinear structural dynamics field to investigate the method's handling of numerical noise and non‐linearity. It is shown that, despite its simplicity, the SRSM method converges stably and is relatively insensitive to its only user‐required input parameter.

Concerns about cybersecurity and attack methods have risen in the information age. Many techniques are used to detect or deter attacks, such as intrusion detection systems (IDSs), that help achieve security goals, such as detecting malicious attacks before they enter the system and classifying them as malicious activities. However, the IDS approaches have shortcomings in misclassifying novel attacks or adapting to emerging environments, affecting their accuracy and increasing false alarms. To solve this problem, researchers have recommended using machine learning approaches as engines for IDSs to increase their efficacy. Machine-learning techniques are supposed to automatically detect the main distinctions between normal and malicious data, even novel attacks, with high accuracy. However, carefully designed adversarial input perturbations during the training or testing phases can significantly affect their predictions and classifications. Adversarial machine learning (AML) poses many cybersecurity threats in numerous sectors that use machine-learning-based classification systems, such as deceiving IDS to misclassify network packets. Thus, this paper presents a survey of adversarial machine-learning strategies and defenses. It starts by highlighting various types of adversarial attacks that can affect the IDS and then presents the defense strategies to decrease or eliminate the influence of these attacks. Finally, the gaps in the existing literature and future research directions are presented.


ofpethidine among those induced early and more meconium stained amniotic fluid among those induced late in another,7 and no significant differences between the groups in the third.8 One postterm trial, very similar in design to ours, was reported while our original manuscript was being considered for publication.9 In that trial Cardozo et al found that more babies in the active management group were intubated and that the same group had slightly lowered cord blood pH, but otherwise there were no differences in outcome. In our trial there were no significant differences in any of the variables concerning labour and delivery. It is fair to conclude that either type ofmanagement appears to be safe, provided that certain conditions in case selection and supervision are met. An intelligent choice must therefore be based on other considerations. The menstrual and pregnancy histories should be scrutinised to ensure that the pregnancy is truly past term. We excluded 373 (40%) out of944 women from the trial because of uncertainty about dates. This proportion is not surprising, given that the proportion of pregnancies with uncertain dates increases with time past term. Furthermore, it is common experience that strict adherence to preset selection criteria in any randomised trial leads to many more exclusions than anticipated. One feature of elective induction is often overlooked and therefore not universally acknowledged-namely, the comparatively high rates of unsuccessful attempts. In each of two studies of postterm induction delivery in 70% ofcases occurred within 30 hours.410 In this trial the success rate was 77% (first attempt in group 1). Success is related to parity and the intensity and duration of oxytocin infusion. The chance of success must be weighed against the inconvenience and risk of prolonged contractions due to oxytocin. In principle the same argument is valid for treatment with prostaglandin. Restricting induction to mothers with ripe cervices (high Bishop scores) naturally increases the success rate. This group, however, has the highest chance of going into spontaneous labour soonest; hence if preventing the postmaturity syndrome is the aim these women may not need induction. The emotional response of some mothers in whom induction attempts fail also deserves consideration. Oxytocin infusion has been incriminated in raised bilirubin concentrations in the newborn." 12 The same tendency was found in this study, in which significantly more children in the induction group needed phototherapy. Though mildy raised bilirubin concentrations may not have serious implications, treatment is clearly demanding of resources. Conclusion


Over the past 20 years, efforts have been made to broadly disseminate evidence-based practices (EBPs). However, the public health impact of EBPs has yet to be realized and most EBPs are not sustained. Few structured models exist for disseminating and sustaining EBPs across large systems. This article describes the EBP Dissemination and Support Center (DSC) model and how it was used to sustain trauma-focused cognitive behavioral therapy (TF-CBT) across Connecticut. More than 600 clinicians at 35 agencies have been trained and nearly all agencies have sustained TF-CBT for up to 9 years. More than 6,200 children have received TF-CBT and have shown improvements in outcomes and quality indicators. Recommendations are made for using or adapting the DSC model.

Tight XFEL focusing is very important for significantly enhancing photon flux density, which is highly demanded by users exploring nonlinear X-ray optics. However, focusing XFEL down to 10 nm or less is so difficult from the viewpoints of both optical fabrication and optical alignment. The former can be overcome using techniques of wavefront sensing and fine shape correction. For the latter, techniques for directly measuring beam size on the focus without an influence of vibration of nanobeam are required. We have developed a technique for determining the size of nanobeam on the focus using an intensity interferometer, based on the Hanbury Brown and Twiss effect, of X-ray fluorescence emitted from a thin film inserted into the focus. The spatial coherence of X-ray fluorescence observed far from the focus depends on the distance from the focus and emission region of X-ray fluorescence. Therefore, the measured coherence can determine the size of X-ray nanobeam. This method has advantages that vibration of nanobeam does not affect the result and the setup is so simple.
A demonstration experiment was performed using a 100 nm focusing system based on total reflection KB mirrors at SACLA. X-ray fluorescence (8 keV) emitted from a thin Cu film by irradiation of focused XFEL pulses (12 keV) was detected shot-by-shot with a dual MPCCD. Analyses of approximately 1000 images based on the autocorrelation revealed that the beam size obtained with this method is in good agreement with one obtained with the wire scan method.


This article constructs actual,optimal and maximum indicators about the effect of personal income tax,transfer payments and an integrated policies system of the two taxes to the income inequality.Analyzing the Chinese data ,we find that China's individual income tax is increasingly deteriorating income inequality and plays a major role in the effects of income inequality.What's more,transfer payments have a certain but weak inhibitory effect on inequality,and the effect goes farther away from the optimal index requirements.The integrated policies system of personal income tax and transfer payments exacerbate income equality and are nowhere near its peak.Finally,This paper presents relevant policy recommendations.

This article focuses on the involvement of Siemens in the market for radiology equipment in Japan between 1900 and 1945. It explores why the German multinational company was unable to keep its dominant position in the Japanese market in the interwar years despite its technological competitiveness. At this time the Japanese medical market was already well structured when the country opened up to the West. In particular, it examines the firm's strategic choices in relation to the changing economic and technological environment, highlighting the importance for foreign multinationals of working together with national trading firms involved in the distribution of drugs and products for doctors.


A new dispersion experiment is developed by connecting the outlet of a short dispersion tube to the pump inlet, forming a closed-loop flow path. Instead of injecting solution samples into a large excess of carrier solution, one half of the circuit is filled initially with solution at concentration + (Δc/2) and the other half is filled with solution at concentration − (Δc/2). Pumping these solutions around the circuit generates exponentially damped concentration oscillations in a refractometer detector. Fourier analysis of the detector signal gives the mutual diffusion coefficient. The average concentration of diffusing solute is constant, so relatively large concentration differences can be used to measure differential diffusion coefficients. Consequently, baseline drift in the detector signal is negligible. Moreover, recirculation drastically reduces the required volume of solution. Closed-circuit dispersion measurements are reported for binary aqueous solutions of sucrose, glycine, urea, NaCl and KCl. The calibrated circuit is used to measure the binary mutual diffusion coefficient of aqueous LaCl

A field experiment was conducted at Adhiparasakthi Agricultural and Horticultural College, Kalavai during Rabi, 2014 to evaluate the influence of organic and inorganic sources of nitrogen on growth and yield of brinjal (Solanum melongena L.). The experimental design was in a Randomized Block Design (RBD), block of 11 treatment replicated thrice using CO 2 Brinjal (Solanum melongena L.) as test crop. The growth characters, viz., Plant height (cm), No. of leaves plant-1, No. of branches plant-1, No. of flowers plant-1 and Yield attributes like total no. of fruits plant-1, Fruit weight (g), Fruit length (cm), Fruit diameter (cm), yield (kg ha-1) were significantly increased by the application of 75% N through inorganic (163.04 kg urea) + 25% N through organic (2.5 t ha-1 vermicompost) which was on par with T11 (50.60 cm) that received 50% N through inorganic (108.7 kg urea) + 50% N through organic (5 t ha-1 vermicompost) and T4 (48.73 cm) that received 75% N through inorganic (163.04 kg urea) + 25 % N through organic (5 t ha-1 FYM). Over all, from the experimental results, it could considered that application of 75% N through inorganic (163.04 kg urea) + 25% N through organic (2.5 t ha-1 vermicompost) as a better option for achieving higher productivity and profitability of Brinjal.


Gridshells are lightweight structures made of interconnected slender beams. Due to large displacements, high interaction between the beams, and bending–torsion coupling, modeling gridshells requires specific non-linear numerical tools to reach convergence within a reasonable time. In this article, the development of such a tool is presented. It is based on the Kirchhoff beam theory and uses the dynamic relaxation method. First, from Kirchhoff's equations, the internal forces and moments acting on a beam are obtained. Once this mathematical work is done, the dynamic relaxation method is used in order to get the static equilibrium configuration of the beam. This new approach is tested on several examples and validated for slender beams with arbitrary rest-state configuration and cross sections. In particular, results for ribbons with high bending–torsion coupling are presented. Finally, this process enables the fast and precise modeling of gridshells including bending–torsion coupling.

Compacts of TiB{sub 2} with densities approaching 100% are difficult to obtain using pressureless sintering. The addition of SiC was very effective in improving the sinterability of TiB{sub 2}. The oxygen content of the raw TiB{sub 2} powder used in this research was 1.5 wt%. X-ray photoelectron spectroscopy showed that the powder surface consisted mainly of TiO{sub 2} and B{sub 2}O{sub 3}. Using vacuum sintering at 1,700 C under 13--0.013 Pa, TiB{sub 2} samples containing 2.5 wt% SiC achieved 96% of their theoretical density, and a density of 99% was achieved by HIPing. TEM observations revealed that SiC reacts to form an amorphous phase. TEM-EELS analysis indicated that the amorphous phase includes Si, O, and Ti, and X-ray diffraction showed the reaction to be TiO{sub 2} + SiC {yields} SiO{sub 2} + TiC. Therefore, the improved sinterability of TiB{sub 2} resulted from the SiO{sub 2} liquid phase that was formed during sintering when the raw TiB{sub 2} powder had 1.5 wt% oxygen.


This review highlights current economic and legal issues relating to lease and fee hunting on private lands in the United States. Recreational hunting leases provide an important practical example of the potential of market-based conservation to create win-win arrangements among rural landowners and hunters. Research suggests that there are significant positive values and economic impacts from fee and lease hunting. Results show that many national trends for hunting on public land and private lands are declining; however, there are important exceptions to those trends (e.g., big game hunting) and differences across states. Given hunting quality on public land, hunters often express a willingness to pay significantly higher than the price charged on private land. Further, institutional innovations can remove legal barriers and positively affect lease and fee hunting on private land. Future research needs include further regional comparisons, case studies on institutional arrangements, as well as additional hedonic pricing and preference studies.

The present work reports the preparation of super hydrophobic and oleophilic sorbent powder for the selective removal of spilled-oil from oil-polluted water surface. The sorbent powder was prepared by the surface modification of commercially available pure barium sulfate (BS) with palmitic acid via a simple one-step synthetic approach. The powder was observed to exhibit super hydrophobic character with a static water contact angle value of 152±2°. The powder also possesses sufficient buoyancy and exhibits high selectivity towards oil, vital for a sorbent for use in oil spill clean-ups. The oil sorption capacity of the sorbent material was also investigated.

A fractal permeability model for nonwoven fabrics is developed based on the fractal characteristics of pores within them. The fractal permeability is found to be related to pore area fractal dimension, tortuosity fractal dimension, size of fibers, the maximum and minimum pore sizes, fabric thickness, and the effective porosity of a medium. To verify the validity of the proposed model, experimental work was conducted on a set of nonwoven fabrics, and the predicted air permeability was compared with the experimental results. Good concordance was found between them. Meantime, the model was also compared with the existing models and is proved to be more accurate.


The logistics and supply chain of pandemic prevention materials is an important pillar of the pandemic prevention and control system, and the information system is the "Nerve Center" that ensures the efficient operation of the logistics and supply chain. Blockchain technology has the characteristics of transparency and credibility, tamper-proof traceability, privacy security and high reliability of the system, and it is of great significance to study how to apply blockchain technology to improve the logistics and supply chain information system of pandemic prevention materials, so as to better cope with the current and possible future pandemic. To this end, this paper uses the literature analysis method and knowledge map method to reveal the research status, hot spots and evolution context of blockchain technology application in the logistics and supply chain information system under pandemic-hit. The research results show that there is a significant correlation between the number and theme changes of relevant literature and the progress of pandemic prevention and control. There have been a number of research hotspots, but they are still relatively scattered. There are few studies on the organic combination of blockchain technology application, pandemic prevention and control, the logistics and supply chain information system. Looking forward to the research trend, in the future, blockchain can be integrated with the Internet of things, cloud computing, big data, etc., so as to ensure the efficient operation of pandemic emergency logistics, help the management of pandemic material donation, and improve the pandemic medical material supply chain information system.


We investigate the steady flow of a shear thickening generalized Newtonian fluid under homogeneous boundary conditions on a domain in R 2. We assume that the stress tensor is generated by a potential of the form H = h(|ε(u)|), ε(u) denoting the symmetric part of the velocity gradient. We prove the existence of strong solutions for a large class of functions h having the property that h ′ (t)/t increases (shear thickening case).

In this work,the bentonite was characterized by Fourier transform infrared(FTIR) spectroscopy,X-ray powder diffraction(XRD),scanning electron microscope(SEM).The sorption of radionuclide 63Ni(Ⅱ) on bentonite was investigated by batch technique under ambient conditions.The effect of contact time,pH and coexistent electrolyte cations on 63Ni(Ⅱ) sorption to bentonite was examined.The results demonstrate that the kinetic adsorption data is well described by the pseudo-second-order model and the sorption of 63Ni(Ⅱ) is strongly dependent on pH and ionic strength at low pH values.The sorption of 63Ni(Ⅱ) is dominated by outer-sphere surface complexation or ion exchange at low pH,whereas inner-sphere surface complexation is the main sorption mechanism at high pH.In addition,the removal of 63Ni(Ⅱ) to bentonite is also strongly affected by FA and cations.


Objective
To assess the safety and effectiveness of sufficient, short-term platelet (PLT) transfusion for the surgery preparation of the infantile patients with Kasabach-Merritt phenomenon, who were insensitive to glucocorticoids.

Methods
The infantile cases were retrospectively analyzed during May 2011 to December 2016, who were clinically diagnosed as KMP and insensitive to glucocorticoids, received PLT transfusion and surgical resection. PLT transfusion in patients whose PLTC was less than 30×109/L, was 0.3 therapeutic dose(TD)/kg, and 0.2 TD/kg in PLTC≥30×109/L group. The maximum was 1 TD.Criteria of the PLT transrusion: 1 hour after the transfusion, the PLT count (PLTC) were tested and the corrected count increment of platelet (CCI) and practical platelet recovery (PPR) was calculated. PLTC ≥100×109/L, CCI>7.5×109/L and PPR>30% were defined as effective; while PLTC=(50-99)×109/L, CCI>7.5×109/L and PPR>30% as partial effective; PLTC<50×109/L, or CCI≤7.5×109/L, or PPR ≤30% were defined as ineffective. By reviewing the method and response of their PLT infusions, to figure out the most effective way in rising PLT, as a part of pre-operation treatment.

Results
There were 46 cases in the research. Based on the PLTC, CCI and PPR 1 hour after PLT transfusion, there were 44 effective transfusion, 2 patients with partial effectiveness, and no ineffective case. There was no allergic or heart failure happened in any cases. No critical potential complications of PLT transfusion occurred, including fluid and iron overload, alloimmunization to human leukocyte antigen and/or PLT antigen.

Conclusions
Pre-operative sufficient and short-term PLT infusions are more effective than low dose and long-term ones. They can create a more optimistic opportunity for surgical resections.

at As this value chain on the chains of carp fish seed (spawn, and fingerlings) in the of purpose of this study is to obtain a clearer understanding of the volumes of fish produced and consumed in Southern Bangladesh and their origin (by system and location), their destination (by type of market, type of consumer and location), and to gain a clearer understanding of potential market based solutions to farmer's problems, which the project could implement. The study was conducted on 91 respondents that covered hatcheries, nurseries, grow-out farmers, trade intermediaries and key informants. The information was collected on five steps-(i) secondary literature review to construct problems on the carp fish seeds value chain and the primary value chain map, (ii) preliminary assessment to collect information on the actors in the carp fish seeds value chain, production and marketing practices based on which questionnaire for in-depth qualitative and quantitative survey was designed, (iii) in-depth qualitative survey, (iv) quantitative survey and (v) data analysis. The end market (type of consumers) for carp seeds vary depending on the type and the size of seeds (spawn, fry, fingerlings, juveniles). The national production of spawn, fry and fingerlings has been estimated to be respectively 19200 crores, 4200 crores and 1200 crores. The total national demand for fingerlings has been estimated to be around 928 crores (500 crores for closed waterbodies and 428 crores for open waterbodies). Given this, there is surplus of 272 crores fingerlings in the national markets. There are as many as 99 operational hatcheries in the southern region, which produced 135 tons spawn or 1353 crores fry, which is about 28% of the total national production. Currently 89% of the spawn produced in the region is sold within the region while the rest 11% is sold outside the southern region.


Targeted at the problem of decision-making for aero-engine delivery and repair, a decision model of engine sending and repairing based on improved artificial fish swarm optimization is proposed. Firstly, aiming at the two key parameters mtry and ntree which affect the classification accuracy in random forest algorithm, a kind of artificial fish swarm optimization algorithm based on adaptive step and field of vision is used to optimize, and secondly, the decision model of engine delivery and repair is carried out on the basis of stochastic forest algorithm. Finally, the model is applied to the case study to classify the real data of a certain type of engine. The results show that the improved artificial fish swarm optimization algorithm is quick and effective, and the more training samples are, the higher the classification accuracy of the stochastic forest algorithm is, and the higher the classification accuracy is. The research can be used for reference to make decision-making in outfield engine, and has important practical significance.


markdownabstractDecades of prior genetic research using twin modelling designs has shown that differences in human behavior are strongly influenced by differences in our DNA. Through advances in DNA genotyping it has become feasible to study the genetic factors that contribute to human variation by large-scale genome-wide association studies (GWAS).
In this thesis, our aim was to study the genetic variants, genes and genetic pathways that explain variation in a broad diversity of behavioral outcomes making use of big data analyses in large population cohorts. By integrating GWAS results and GWAS-derived polygenic risk scores with gene-expression data, functional gene-sets and MRI imaging of the brain, this thesis provides a step forward in understanding the association between genetic variation and health-related phenotypes, including intelligence, neuroticism and depression, and insomnia, and the pathways and cell-types in the brain through which these genetic factors act.

Mn−Co−O nanocrystals, ranging from pure cobalt oxides to pure manganese oxides, were anodically electrodeposited on stainless steel substrates. Detailed structural characterization of as-deposited Mn−Co−O nanocrystals was conducted using wavelength-dispersive spectroscopy (WDS), X-ray photoelectron spectroscopy (XPS), and transmission electron microscopy (TEM). WDS and XPS results suggest that there is an inherent cation deficiency associated with the as-deposited nanocrystalline oxides. Experimental selected-area diffraction (SAD) ring patterns obtained from these oxides are consistent with simulated SAD ring patterns of a defective rock-salt-type phase, in which a significant number of cation vacancies reside on the octahedral interstices in the rock-salt-type unit cell. Additional diffracted spots were also observed between the (200) and (220) reflections, which may be attributed to ordering of Mn vacancies in the rock-salt-type unit cell. The formation of this type of defective rock-salt structure is ...


In 1997, a precast prestressed T-Beam in the Ala Moana Shopping Center Parking Garage was strengthened in flexure using carbon fiber reinforced polymer (CFRP). When the old parking garage was demolished in June 2000 to make way for a new multilevel parking garage, this beam and two control beams were salvaged and transported to the University of Hawaii at Manoa Structural Testing Laboratory for testing. This report presents testing of the strengthened beam and a control beam. It also describes the retrofit procedures during field application of the CFRP strips, beam recovery, and preparation for laboratory testing. In addition, a step-by-step analysis of the predicted strengths is presented. To ensure flexure failure, the beams were retrofitted in shear with CFRP. Two types of wrapping scheme were used and anchorage was provided for the shear retrofit. The left half of each beam was retrofitted with 3" wide double layer CFRP stirrups. The right half of each beam was retrofitted with 12" wide CFRP sheets. After flexural testing, each half of each beam was recovered for shear testing. Flexural test results indicate that the CFRP strengthening provided a 71% increase compared with the control specimen without reducing the beam's ductility. The flexural capacity of the strengthened beam was 21% greater than predicted by ACI 440R-02. The two T-Beam tests with CFRP sheets for shear strengthening produced 7% and 16% increases in the shear capacity when compared with the control beam without CFRP shear strengthening. These increases are below the 42% increase predicted by ACI 440R-02. Because of conservatism in the estimate of concrete and internal steel stirrup contribution to the shear capacity, the failure shear strength of the beams with CFRP sheets was still slightly greater than the ACI 440R-02 prediction for ultimate shear capacity. The shear tests indicated delamination of the CFRP stirrups and sheets occurring prior to the maximum shear load. Anchorage at the top and bottom of the beam web helped prevent complete delamination of the CFRP; however further anchorage development is required to improve the strength of the CFRP shear retrofit.


Abstract A serological test for staphylococcal enterotoxin, using a microslide gel diffusion technique, was employed to examine 4.07million pounds of cheese suspected of containing staphylococcal enterotoxin A. The sensitivity of the microslide gel diffusion method was determined with purified enterotoxin A. A concentration of 0.4 μ g/ml of enterotoxin A was detected by this technique. The procedure of extraction and concentration of the enterotoxin in cheese permitted the detection of 0.3 μ g of enterotoxin A per 100g cheese, with a recovery of 16 to 35%. To test 4.07million pounds of cheese, each of ten persons was trained to do a specific portion of the method. Testing of 24 to 40 samples was initiated daily and samples in process were continued to completion. Eight to ten days elapsed from the start to the completion of analysis of a sample. Of the 2,112 vats of cheese tested, 59 were found to be toxic. One of the more toxic vats contained approximately 12 μ g of enterotoxin A per 100g of cheese. The vats of cheese found to be toxin-free were released and consumed with no reported illness.


We report a novel analytical approach to identify individual components of a cell's endogenous fluorescence, recorded by spectrally-resolved time-correlated single photon counting (TCSPC). Time-resolved area-normalized emission spectroscopy (TRANES) and principal component analysis (PCA) were applied to estimate the number of spectral components after metabolic modulation of cardiac cells following excitation with a 375 nm picosecond laser. Linear unmixing of TCSPC data spectrally decomposed individual components in living cells, while using characteristics of endogenously fluorescing molecules in solvents as a reference spectral database. Our data demonstrate the presence of three individual components, corresponding to the nicotinamide adenine dinucleotide (phosphate) (NAD(P)H) in organic and inorganic solvents and to the residual flavoprotein fluorescence. The presented analytical approach offers a new alternative for the spectral separation of multi-wavelength fluorescence lifetime spectroscopy data to the conventional analysis, and opens a new possibility for the use of pattern recognition for fast resolution of components in 2D fluorescence lifetime microscopy images.


Leventhal and Allbee in The Victim were both victims and sufferers.Their sufferings and the absurdity as victims constituted their doubly paradoxical situation.Their suffering was caused,to a large extent,by anti-Semitism at that time.Allbee was internally assimilated by the anti-Semitic ideology,which he in turn applied to Leventhal.They thus are mingled together both as the persecutor and the persecutee.Leventhal didn't think that he should bear any responsibility for Allbee's life,nor did he feel any guilty of his behavior.However,he finally chose to take the responsibility for Allbee because of his belief in the Jewish ethical thought "love neighbor as thyself".The novel demonstrates the positive significance of sufferings exerted on victims,encouraging people to strive harder and to ultimately free themselves from pain.

Generalized Departure Time is a response function of travellers who are appointed the place and time for arrival, and GDT gives their departure time as a function of the operational properties of transit system. The validity of such a concept is to be verified by the actual application in various cases because GDT is a "constructive concept" to be conjectured and the way of conjecture is not forgiven. This paper describes the method to estimate GDT of mass transit passengers in order to serve such verification. It also reports that commuters' GDTs estimated in Hiroshima and Tokyo are quite alike.

The new science National Curriculum for England (DfEE/QCA, 1999) stresses the importance of sustainable development; conservation of biodiversity is a fundamental issue in this debate. This article discusses the findings of a study of the views of 15 and 16 year-olds on the importance of biodiversity conservation. There was general disapproval for human economic activities that might threaten wildlife with extinction, although significantly fewer boys than girls held this view. Interviews with pupils indicated a discernible lack of knowledge about the existence and importance of lower organisms, and the impact of farming and forestry on wildlife. Pupils showed a positive attitude towards conserving some groups of organisms and a negative attitude towards others. The commonest reasons given for not wishing to conserve organisms were that they were harmful or inferior to humans.


A well-known phenomenon of multimodal language is the synchronous coupling of prosodic contours in speech with salient kinematic changes in co-speech hand-gesture motions. Invariably, such coupling has been rendered by psychologists to require a dedicated neural-cognitive mechanism preplanning speech and gesture trajectories. Recently, in a continuous vocalization task, it was found that acoustic peaks unintentionally appear in vocalizations when gesture motions reach peaks in physical impetus, suggesting a biomechanical basis for gesture-speech synchrony (Pouw, Harrison, & Dixon, 2019). However, from this rudimentary study it is still difficult to draw strong conclusions about gesture-speech dynamics in (more) complex speech and the precise biomechanical nature of these effects. Here we assess how the timing of physical impetus of a gesture relates to its effect on acoustic parameters of mono-syllabic consonant-vowel (CV) vocalization(/pa/). Furthermore, we assess how chest-wall kinematics is affected by gesturing, and whether this modulates the effect of gestures on acoustics. In the current exploratory analysis, we analyze a subset (N = 4) of an already collected dataset (N = 36), which serves as the basis for a pre-registration of the confirmatory analyses yet to be completed. Here we provide exploratory evidence that gestures affect acoustics (amplitude envelope and F0) as well as chest-wall kinematics during mono-syllabic vocalizations. These effects are more extreme when a gesture's peak impetus occurs closer to the center of the vowel vocalization event. If the current findings can be replicated in confirmatory fashion, there is a more compelling case to be made that gesture-speech physics is important facet of multimodal synchrony.

As the amplitude of the rotor fault feature components are always submerged in the fundamental components, they are difficult to be detected by the conventional Fourier transform, this paper takes advantage of the distinguishing feature of the wavelet transform in discerning mutable signal to extract them. Firstly, Morlet wavelet is chosen as the mother wavelet, and the current signal of the stator is analyzed by MRA, subsequently, with the reconstruction of the selected sub-spaces??the motor's fault feature components are extracted successfully, which provides an effective way for the on-line diagnosis of the induction motors.


The lateral transport and degassing of carbon in riverine ecosystems is difficult to quantify on large spatial and long temporal scales due to the relatively poor representation of carbon processes in many models. Here, we coupled a scale‐adaptive hydrological model with the Dynamic Land Ecosystem Model to simulate key riverine carbon processes across the Chesapeake and Delaware Bay Watersheds from 1900 to 2015. Our results suggest that throughout this time period riverine CO2 degassing and lateral dissolved inorganic carbon fluxes to the coastal ocean contribute nearly equally to the total riverine carbon outputs (mean ± standard deviation: 886 ± 177 Gg C·yr−1 and 883 ± 268 Gg C·yr−1, respectively). Following in order of decreasing importance are the lateral dissolved organic carbon flux to the coastal ocean (293 ± 81 Gg C·yr−1), carbon burial (118 ± 32 Gg C·yr−1), and lateral particulate organic carbon flux (105 ± 35 Gg C·yr−1). In the early 2000s, carbon export to the coastal ocean from both the Chesapeake and Delaware Bay watersheds was only 15%–20% higher than it was in the early 1900s (decade), but it showed a twofold increase in standard deviation. Climate variability (changes in temperature and precipitation) explains most (225 Gg C·yr−1) of the increase since 1900, followed by changes in atmospheric CO2 (82 Gg C·yr−1), atmospheric nitrogen deposition (44 Gg C·yr−1), and applications of nitrogen fertilizer and manure (27 Gg C·yr−1); in contrast, land conversion has resulted in a 188 Gg C·yr−1 decrease in carbon export.


In this paper, a new method of low frequency multiple-point equalization for room acoustics is presented. This approach is theoretically based on Common Acoustical Pole (CAP) modeling of the room transfer functions developed previously by Haneda et al. [1]. With the hybrid approach, the multiple-point equalizer is made up with cascaded notch filters which coefficients are directly determined from the CAP model. This new method reduces the complexity of the equalizing structure in addition to an automatisation of notch filters design which should be very attractive to many applications such as home theater systems by intelligently controlling room modes.


The railway tracks are backbone of railway transportation. The cracks in the tracks and slipper misplace creates biggest problem in railway transportation. These cracks are not easily detectable by human eye and it takes more time to resolve. To avoid this problem, we use crack finding and slipper misplace detecting robot, which indentify the cracks and slipper misplace tracks and gives indication to remote station. A ROBOT is device designed to carry out one or more tasks without human intervention with speed accuracy. An independent ROBOT acts as on your own structure completes with its controller. The most developed ROBOT is manufactured in artificial intelligence schemes that can be trained from its surrounding and knowledge build its ability based on that facts. The fourth largest network in the world is an Indian Railway after USA, Russia and China. There are stern problems of accidents of railways. So Indian railway looking forward to promoting the motto of "SAFE JOURNEY"


This paper investigates into the utilitarian features of academic writing and its influence upon the qualities of college journals. The large amount of utilitarian papers will not only pose great difficulty to the selection and adoption of high-quality academic writings, but it will lead to academic corruption and do great harm to the quality and reputation of college journals. In this respect, college journals should be strict in paper selection, improve the editors' professional qualities, try all means to single out high-quality papers, prevent the occurrence of academic corruptions, and take measures to punish the utilitarian writers who have committed serious violation against academic virtues. Only in his way can the academic environment be purified and the academic integrity be maintained.


"When the United States acquired Russian Alaska, North America lost a culture."' Although the Alaska purchase took place in 1867, vestiges of Russian culture are still plentiful in Alaska. To discover Alaska's Russian past one has only to look at place names like Baranof Island, Shelikof Strait, Semisopochnoi Island, and Point Romanof; see the many native settlements where the Russian Orthodox church is a prominent ediface; and visit villages such as on Kodiak Island, where one discovers that Raymond is actually Roman and Willy Vasilij. The extent of this contact can be seen in the Russian loan words present in modern-day Eskimo, Aleut, Athapascan, and Tlingit. The most pronounced influence is to be found in Aleut (Aleuts were the first native peoples to make contact with the Russians) and two of the Yupik (Western) Eskimo dialects, Central Yupik and Suk Eskimo. Other Yupik dialects such as Cuk (spoken on Nunivak Island) and Siberian Yupik (spoken on St. Lawrence Island forty miles from Siberia as well as on the Cukbi Peninsula in Siberia), experienced little Russian influence. The full extent of the interaction of Alaskan native

Patterns, and particularly banded patterns, are widely reported in dryland vegetation, and have been the subject of considerable modelling effort. However, much of this modelling effort is predicated on a mathematical approach that is designed to produce patterns and relies on physical processes that are unreasonable. In consequence, whereas in nature dryland vegetation patterns are irregular, disjointed and discontinuous, those produced by such models tend to be regular, continuous and even. The question, therefore, arises "Is it the irregularity, disjointed and discontinuous character of these patterns that holds the key to their formation rather than any apparent, human-imposed semblance of regularity and continuity?" By focusing on this apparent patterning have such models rejected as noise the key to understanding the signal? Models that produce regular vegetation patterns, typically do so by imposing global rules (largely for the distribution of water). Is it not more likely that vegetation responds to the local supply of water, nutrients and propagules? Here, we present a model for the growth of vegetation in deserts that is predicated on the local conditions of input of water, nutrients and propagules and output, such as loss of biomass by herbivory. The approach represents our best quantitative understanding of how desert ecosystems work. Patterns emerge that show the irregularity and discontinuity seen in nature. By focusing on the process rather than the patterns per se our model has the ability to address specific questions of the role of such patterns in land degradation. Further, it has the potential to provide quantitative estimates of the response of the landscape to specific management strategies, as well as the identification of the key thresholds and tipping points that are so important to the management of drylands. In providing a way to understand and predict the vegetation patterns that may develop during desertification, the approach also represents a crucial potential tool for its management and even reversal.


This paper studies the effect of graduating from college on lifetime earnings. We develop a quantitative model of college choice with uncertain graduation. Departing from much of the literature, we model in detail how students progress through college. This allows us to parameterize the model using transcript data. College transcripts reveal substantial and persistent heterogeneity in students' credit accumulation rates that are strongly related to graduation outcomes. From this data, the model infers a large ability gap between college graduates and high school graduates that accounts for 54% of the college lifetime earnings premium.

This article presents an atomic scale model of single strand DNA based Hydrogen gas sensor using Density Functional Theory conjugated with Non-Equilibrium Green's Function based first principle approach. This device is designed to detect the presence of Hydrogen gas through its current-voltage response and by change in conductivity. The quantum transport property of the gas sensor shows that when the DNA molecules adsorbed Hydrogen gas then the quantum transmission of the biomolecules has been increased even at room temperature operation. The adsorbed gas particles play an important role in the quantum ballistic transmission of the biomolecular gas sensor which results in the creation of sharp transmission peaks near Fermi level. Though weak coupling exists between the biomolecules and electrodes in the Coulomb-blockade regime but still it encourages incoherent transmission which results in sequential tunneling. During Hydrogen gas adsorption the tunneling capability is modified and results in strong quantum transmission. Single strand DNA is able to detect the presence of Hydrogen gas when it is coupled with a Gallium Arsenide nanopore two probe electrodes. First principle results reveal that significantly large current is achieved due to the sensitivity of the DNA molecules in the presence of Hydrogen gas. These theoretical analyses suggest that DNA is able to detect and monitor the presence of Hydrogen atoms after charge stabilization in Coulomb-blockade regime and also under controlled bias voltages. The current and conductivity of the biomolecules increase dramatically upon the adsorption of Hydrogen, which suggests that this system has potential application as a biomolecular sensor.

In this review, various aspect concerning the resolution of capillary electrophoresis for
nine standard peptides ( namely, bradykinin, bradykinin fragment 1-5, substance P,
Arg-vasopressin, luteinizing hormone·releasing hormone (LHRH), bombesin, leucine-enkephalin,
methionine-enkephalin and oxytocin). The experiment were carried out
using 100 mM phosphate buffer as the separation buffer, added with acetonitrile
(ACN) and triethylamine (TEA) as an additive at low pH. The resolution of these
peptides was examined at different concentrations of ACN ( 0, 10, 20, 30, 40, 50 and
60 %) and TEA ( 0, 5, 10, 20, 30, 40 ppm) at their respective final pH. The results
showed that the resolution was improve when 10 % of ACN added in the BGE. The
optimum resolution found at 40 % ACN where all peptides were resolved at baseline.
The shape was perfectly symmetrical. As for the TEA addition, adding 5 ppm already
improve the peaks and addition of 30 ppm TEA gives the optimum resolution
compare to all. For both ACN and TEA, adding more concentrated additive gives poor
resolution of peptides. The investigation was continued by applying voltage ( 23, 24,
25,26 and 27 kV). Shorter time separation achieved when voltage increased. The best
resolution found at 25 kV. However, more voltage caused poor resolution.


The present paper is concerned with a well-defined type of strabismus which represents, in our experience, an unsolved problem in this field, i.e. constant manifest strabismus of early onset (before the 3rd birthday). In all the patients examined (aged from 6 to 18 years) the visual acuity was good in both eyes (not less than 5/10 with the Monnoyer test chart) because the strabismus was alternating or because the amblyopia had been at least partly cured. The clinical examination was carried out in normal surroundings using Bagolini's striated glasses with the aid of a bar of red filters in the presence of deep suppression (Bagolini 1957, 1958). These glasses are transparent lenses superficially streaked on one surface so that a thin luminous line appears against a light source while the perception of the surroundings is unchanged (Fig. 1).


Using the Pearl River Delta in China as a case study, we found the Asian financial crisis in 1997 had more significant impacts on service sectors, whereas the 2008 global financial crisis exerted more influence on export-oriented manufacturing industries. Before the 2008 crisis, cities had been synchronising in manufacturing expansion. After the crisis, manufacturing expansion became unsynchronised, whereas service industries started to keep growing at relatively high and stable growth rates. In addition to expansion phases which are common in China, we found contraction phases of the employment cycles which were caused by the financial crises. Although most cities in the area took off with labour-intensive manufacturing at the beginning of the economic reform, the industrial structures of the area have evolved into an integrated industrial network through industrial specialisation, functional diversity and collaboration. This change is principally due to self-motivated, crisis-motivated and government-motivated industry restructuring. One characteristic of this industrial network is the complementary relationship between the central city and its surrounding areas. The former provides modern service industries for the latter. A panel model regression confirms that tertiary industries, especially high-tech and high-earning sectors, have significantly positive effects on economic growth after the global crisis.

MapReduce is a cost-effective way to achieve scalable performance for many log-processing workloads. These workloads typically process their entire dataset. MapReduce can be inefficient, however, when handling business-oriented workloads, especially when these workloads access only a subset of the data.
 HadoopToSQL seeks to improve MapReduce performance for the latter class of workloads by transforming MapReduce queries to use the indexing, aggregation and grouping features provided by SQL databases. It statically analyzes the computation performed by the MapReduce queries. The static analysis uses symbolic execution to derive preconditions and postconditions for the map and reduce functions. It then uses this information either to generate input restrictions, which avoid scanning the entire dataset, or to generate equivalent SQL queries, which take advantage of SQL grouping and aggregation features.
 We demonstrate the performance of MapReduce queries, when optimized by HadoopToSQL, by both single-node and cluster experiments. HadoopToSQL always improves performance over MapReduce and approximates that of hand-written SQL.


ABSTRACT Using geographical information system (GIS) analyses, we integrate archaeological and environmental data in order to examine the changing social landscape in a portion of the central Mesa Verde region between A.D. 1050 and 1290. We identify the largest and most persistent communities in this area and define their agricultural catchments. These catchments overlapped increasingly through time, creating a social landscape in which people competed increasingly for agricultural land. We quantify agricultural production in these community catchments by year and find that on average, productivity decreased through time. We use these results to evaluate how catchment overlap affected the productive potential of each community and whether the increased competition for land stimulated cooperation and/or conflict among communities.

Bauer had two main objectives with the study: one, a more general investigation of the relation between democratization and civil society; and two, more specifically, what room was there for the trade union movement in Namibia to develop into a viable political opposition movement and why this has not succeeded thus far. She is also testing the assumption that trade unions are the best predictor of the frequency of political protest in Africa. The book is a culmination of two years of fieldwork for her doctoral degree in Namibia between 1991 and 1993. Bauer traces the history of the Namibian trade union movement, the National Union of Namibian Workers (NUNW) from the general strike in 1971 in when more than 13 000 contract workers shut down the country's mines and work centres. Official South-West Africa People's Organization (SWAPO) publications attribute the strike to the organizing abilities of the nationalist movement, but Bauer demonstrates that the organizers acted independently of SWAPO and that the strike took SWAPO by surprise. She then proceeds to examine the relation between SWAPO in exile and organized labour throughout the 1970s and 1980s and concludes that SWAPO had always shown clear antipathy towards unions. In fact, SWAPO had always been suspicious of any other political activity among the black population, outside of its remit as 'official liberation movement'. Bauer documents the torture of many labour leaders by SWAPO as well as those facing accusations of spying for South Africa. In the late 1980s, the National Union of Namibian Workers (NUNW) under Ben Ulenga reached its zenith – by 1987 nearly every sector of the Namibian economy had been unionized, resulting in SWAPO beginning to seriously question the trade union movement's strength. Bauer then documents the swift transition to a market-driven economic policy by the new independence government post-1990. She ends the book by exploring the links between the SWAPO elite and the dominant business community in the mid1990s at the expense of the union movement. Throughout the book, though the central questions remain: When the trade unions existed in Namibia, why were they so weak? More importantly, what are the implications of the weakness of trade unions – in theory an important political, economic and social force in Namibian society – for the prospects of democracy in Namibia? Bauer's explanations for the weakness of the trade union movement to play a significant opposition role post-independence are threefold: a fragile economy (low level of industrialization, which militates against a strong trade union movement), the colonial legacy of repression and reform, and the unions origins within the nationalist movement-cum-ruling political party. Bauer's analysis makes for depressing reading for the prospects of consolidation of democracy in Namibia, particularly as the country is showing increasing signs of movement towards a oneparty-dominant system, one that is increasingly less tolerant of dissenting voices. She does not have much hope for the trade union movement developing into a viable political opposition. Her study also makes for interesting reading in the Book reviews Progress in Development Studies 1, 4 (2001) pp. 343–370


We have developed a two-dimensional flat-panel imager (FPI) utilizing conventional amorphous silicon (a-Si) thin film transistor (TFT) technology for AM-LCDs, and we have made a prototype. We can experimentally manufacture the FPI basically by utilizing conventional production lines of AM-LCDs, because the imager is based on the TFT array for AM-LCDs. The TFT performs both switching and photo-detecting functions itself. Using the FPI, we can capture monochrome images in real time, and can also achieve full-color images by introducing time-sequential driving based on a color backlight system with RGB-LEDs. The reliability of the TFT under bias and irradiation stress caused by capturing images is maintained by introducing an original driving method and processing the captured image. By making use of advantages the FPI has over conventional imaging systems, we hope that the FPI will be a useful compact imaging device for documents, pictures, fingerprints, and the like.


Abstract. The ultraviolet to visible continuum generations are experimentally demonstrated by coupling femtosecond pump pulses around 800 nm into the normal dispersion region close to the zero-dispersion wavelength in the fundamental mode of a silica photonic crystal fiber (PCF). The ultraviolet to visible continuum is generated through a combination of nonlinear effects including degenerate four-wave mixing, cross-phase modulation, and stimulated Raman scattering. When pump pulses with the wavelength of 800 nm and the input average power of 500 mW are used, more than 40% of the incident pump power is converted to the ultraviolet to visible spectral region. The evolution of the output spectra for different PCF lengths is studied to understand the nonlinear propagation dynamics during the process of the continuum generation. The ultraviolet to visible continuum generation will find important applications in the ultraviolet and visible-based biophotonics and spectroscopy.


This paper concerns the specific experience of our Laboratory in managing archaeological excavations on a GIS platform; the development process of our solution started five years ago and brought us, through successive stages of refinement, to an efficient data model. The basic idea was to reproduce on a graphic level the exact situation we find in the field. We therefore organised our objects according to an overall composite plan representing all the excavated layers, as well as the necessary landscape features, related only in spatial terms; detailed alphanumerical data and interpreted information were derived from the DBMS using specific identifiers. The objects were organised in views according to different parameters and queries; examples of views we created involved the surrounding landscape (e.g. with archaeological surveys, land cover and use, geology, etc.), preliminary investigations (with analytical surveys and crop-marks detection), and stratigraphical data (with a composite plan of all layers as well as analytical views based on chronological aspects, excavated structures, etc.).


Rapidly solidified Al 87 Ni 7Cu 3Nd 3 metallic glasses were prepared by using melt spinning. Its calorimetric behavior was characterized by using differential scanning calorimeter. The metallic glasses were partially crystallized under continuous heating regime. Primary crystallization was studied through structural characterization of the amorphous and partially crystallized ribbons by means of conventional X ray diffraction and transmission electron microscopy with selected area electron diffraction. The results show that, the as spun ribbons are fully amorphous and homogeneous on the micron scale, but contain high density of nanoscale quenched in clusters or crystallite embryos. Primary crystallization mainly leads to formation of two phase mixture of α Al nanocrystalline and residual amorphous phase. Precipitation of α Al nanoparticles is limited by build up and overlapped diffusion field of solute atoms with low diffusion rate. At the earlier stage of primary crystallization the crystal nuclei exhibit high density and growth rate. With the α Al crystal growing, the crystal growth rate decreases, and even at the later stage further crystallization into α Al crystal becomes difficult to occur due to thermal stabilization of the residual nickel and neodymium enriched amorphous phase, the saturated values of crystallized volume fraction and α Al crystal diameter getting to 20%30% and 515 nm.

porous membrane and the chambers. Combustion fuel is supplied to the porous membrane so that surface com bustion takes place at the surface of the porous mem brane facing the chamber for burning the refuse con tained in the chamber. Electrical means may also be employed to provide combustion of the refuse. Safety features include pressure feed-back means for monitor ing and regulating the pressure within the apparatus and temperature feed-back means for monitoring and regu lating the temperature within the apparatus. A particle bin is positioned below the chamber for receiving burned particles from the chamber. The gases generated from the burning refuse is collected and pumped through a super heating and purifying chamber (elimi nated all hazardous affluent) and into the boiler type heat exchanger and thereby producing steam for electri cal generation. The electricity produced is then par tially used to run a cryogenic plant which produces liquid oxygen which is used to produce oxygen gas, the major fuel component, used to produce the surface combustion used in the incinerator. Therefore a tri-gen eration system is generated which reduces operating cost, increase operating efficiency of the incinerator and the bi-produce sold to others generate an off-setting income.


Wear and frictional behaviours of polypropylene (PP) and 10%, 15%, 17.5 % glass fiber reinforced polypropylene (GFRPP) materials were studied against SAE1040 steel counterface block-on-ring apparatus at different sliding speeds and constant normal force load. Increasing the sliding distance increases the weight loss at all speed tested. 200 rpm wear rates are increased irrespective of reinforcement rates and for the maximum rotational speed (500 rpm) wear rates are de creased irrespective of reinfocement rates. Thermo-mechanical properties of glass fiber reinforced PP were examined using DSC and Shore D hardness devices. Microstructures of worn surface of the tested materials were inspected by scanning electronic microscope (SEM) and wear mechanism of the tested materials were studied. Worn surfaces of the tested materials showed that the adhesive wear played an important role for pure polypropylene and with the addition of glass fiber, the wear mechanism was a combination of adhesive and abrasive wear.


The aim of this paper is to research, theoretically and empirically, the impact of institutional reforms on the economic growth in transition countries (new EU members) and Croatia, in the period from 1996 to 2012. In order to prove the hypothesis, we will use panel analysis of transition economies and Croatia, namely the Arellano-Bond dynamic panel analysis. The analysis includes two dependent variables (GDP/pc and the share of export in GDP) and five independent variables (total Heritage Index of Economic Freedom, WGI government effectiveness indicator, WGI rule of law indicator, corruption perception index and the index of institutional reforms in transition countries). The results show that there is a significant positive impact of institutional reforms on the 1 When citing this paper please refer to altered and modified version of this paper: Buterin, V., Škare, M., Buterin, D.

How to effectively enhance the reliability robustness in high-voltage BCD processes is an important issue. A p-channel lateral-diffused MOSFET with an embedded SCR which is formed by implanting N+ doses in the drain side and divided into five regions, this structure called as the "pnpnp" arranged-type of pLDMOS-SCR in this paper (diffusion regions of the drain side is P+-N+-P+-N+-P+). Then, altering the layout topology of N+ implants in a drain-side P+ region is evaluated in this paper by a 0.25-μm 60-V BCD process. In this planning idea, the layout manners of P+ region are discrete-islands in the drain-end. From the experimental results, due to all of their secondary breakdown current (It2) values are so good reached above 6 A, it can be found that the layout manner of discrete-island distributions in the drain-side have some impacts on the anti-ESD and latch-up immunities. However, the major repercussion is the Vh value will be decreased about 66.7% ~ 73.7%.


Designing a solar array regulator requires in-depth knowledge of the solar array itself. Whilst the static response tends to be at the core of the design, its dynamic response also has to be taken into account. In order to do so, the capacitance, and more broadly speaking the impedance, of the solar array must be measured, or evaluated. The measurement of a solar cell impedance is a complex endeavor as the factors influencing the dynamic behavior of a solar cell are varied. Extracting the impedance of a given solar cell requires a specific and non trivial test bench. Leveraging the recent advances in test equipment, the objective of the test setup described herein is to provide a direct method of impedance measured for solar cells under varied conditions to extract the electrical equivalent circuit and parameters. Varied methods will be presented and discussed as well as the rationale behind the chosen test setup.


This study first demonstrated the feasibility of using the photoalignment method to adequately control the structural anisotropy of pentacene films, which are active semiconducting layers, in thin-film transistors (TFTs) with conspicuous anisotropic electrical characteristics. The photoaligned pentacene films were characterized with respect to structure and morphology using x-ray diffraction, atomic force microscopy and Raman scattering. Compared to the uncontrolled pentacene films, a maximum 25-times increase in field-effect mobility (up to 0.82 cm2/Vs) is achieved in the photoaligned pentacene-based TFTs by aligning pentacene orientation parallel to the current flow direction using a photoaligned polyimide layer. Mobility anisotropic ratios ranging between 2.7-8.3 for the current flow parallel and perpendicular to the alignment of the photoaligned pentacene films have been observed for photoaligned pentacene-based TFTs.


Public packet switching networks around the world use CCITT Recommendation X.25, which is the standard device-independent interface between packet networks and user devices operating in the packet-mode. Since its development in 1976 and with four years of network operational experience, the X.25 interface specification has reached a high level of maturity. A revised version of X.25 has been approved by CCITT Study Group VII at its meeting in February 1980. The revised X.25 specification is more complete than its predecessor, eliminates a number of ambiguous areas which lead to network implementation differences, and has been enhanced by the addition of new capabilities both to the X.25 interface and to the end-to-end service. This paper presents a consolidated view of the end-to-end characteristics of the virtual-circuit-based services accessible through the X.25 interface. It then discusses the characteristics of the revised X.25 interface, with emphasis on areas that have been addressed in the revised Recommendation. The revised Recommendation leads the way to greater commonality among network implementations. The increased functionality of the end-to-end virtual-circuit services has impact on the relationship of X.25 to system architectures being discussed by international standards bodies.


During more than 20 years JAXA history on spaceborne and airborne SAR, L-band SAR has been adopted under the unique mission goal, i.e., the global observation. Over the JERS-1 SAR's essential findings on the surface deformation and the deforestation monitoring, both of which owe to the signal penetration of vegetation at L-band, ALOS has achieved the wider and more comprehensive global understanding of the earth phenomena covering four spheres, i.e., largely biosphere, geosphere, cryosphere, and the hydrosphere, and it also contributed the disaster monitoring. On the other way, the airborne SAR has been developed and utilized for investigating the future technology development and the applications, i.e., polarimetric application and the interferometric application.


Magnetic resonance spectroscopy (MRS) and spectroscopic imaging (MRSI) are two of the most demanding and interesting areas of magnetic resonance. The signals of interest are small, and must be acquired in the presence of water and lipids signals that are four orders of magnitude larger. One of the most important tools for MRS and MRSI is the ability to selectively manipulate the magnetization with radio frequency (RF) pulses. These can provide selectivity in space, frequency, and relaxation times T1 and T2. This presentation outlines the basic ideas behind RF pulses, describes the types of operations RF pulses can perform, and then goes through the various different types of RF pulses and pulse design methods. The goal is to give an overview of what RF pulses can do, and where to look for more information. A good reference for all of these topics is the book by Bernstein, King and Zhou [1].


Much has been written about Requirements Elicitation within small and large organisations. Surprisingly, the organisation type played a small role in the software engineering literature and therefore startups, a special type of Research & Development environment, did not receive the attention they reserve in research. Startups are a major factor of the economy's growth and researchers in economic sciences have realised, that existing processes cannot simply be applied to startups. In this paper, a research project on Requirements Elicitation in startup companies is presented. A definition of startups and their distinction from traditional companies is given, Requirements Engineering and Elicitation, as well as their role in Software Engineering and Software Development investigated. A literature review is looking at existing work concentrating on Software Engineering in startups and is showing a lack of empirical research and the need for proper guidance on the handling of requirements in startups. An evaluation-based research approach is introduced that consists of a survey and multiple-case study. Its goal is to understand Requirements Engineering in startups, to provide empirical evidence of the usefulness of identified methodologies and propose guidelines for startups to adopt software methodologies that support Requirements Elicitation. Guidance for software startups will be beneficial, due to their lack of time and money for designing their own development processes. Furthermore, the outcomes of this study could be applied to other organisational forms that intend to foster agility, and to establish an innovative model to study implications of innovation, creativity, immaturity and speed-to-market through concentrated research.

The natural concentration of arsenic in soils may range from 1-40 mg/kg, whereas soils overlying sulphide ore deposits in Western Australia may contain several hundred mg arsenic per kg. The greater concentration of arsenic exists within the orebodies and their immediate surrounds, and values in the thousands of mg/kg are often recorded. As a result, high arsenic levels are often found in gold tailings milled from these orebodies. Environmental considerations require that local native species are established on tailings storage facilities (TSF). Uptake of arsenic by these plants is a concern, but there is little information available to allow the potential risks to be assessed in an Australian context. A glasshouse experiment was conducted using arsenic-rich gold tailings as the growth medium. The aim was to determine if native plants accumulate arsenic, and their growth response in the tailings. A complementary field survey assessed accumulation of metals in native plant species growing on historic and more recent TSF's in the Western Australian rangelands. In the glasshouse experiment, survival and growth of native species was far greater on low-arsenic material than on the arsenic-rich tailings. All the plants that survived in the tailings took up arsenic with concentrations ranging from 6 to 66 mg/kg, depending on plant species and the level of phosphorus application. In the field, there were substantial interspecific differences in the concentration of arsenic in leaf material, for plants growing in arsenic-rich materials. For example, Atriplex species accumulated relatively little arsenic, even at high soil concentrations. By contrast, another chenopod, Maireana pyramidata, appeared to consistently take up larger quantities. Species of other genera appeared to fall in a range between these two. In preliminary comparisons of washed and unwashed Atriplex plants, it appeared that considerable quantities of arsenic may


Recommendation has become one of the most important components of online services for improving sale records, however visualization work for online recommendation is still very limited. This paper presents an interactive recommendation approach with the following two components. First, rating records are the most widely used data for online recommendation, but they are often processed in high-dimensional spaces that can not be easily understood or interacted with. We propose a Latent Semantic Model (LSM) that captures the statistical features of semantic concepts on 2D domains and abstracts user preferences for personal recommendation. Second, we propose an interactive recommendation approach through a storytelling mechanism for promoting the communication between the user and the recommendation system. Our approach emphasizes interactivity, explicit user input, and semantic information convey; thus it can be used by general users without any knowledge of recommendation or visualization algorithms. We validate our model with data statistics and demonstrate our approach with case studies from the MovieLens100K dataset. Our approaches of latent semantic analysis and interactive recommendation can also be extended to other network-based visualization applications, including various online recommendation systems.


This study takes "the survey of junior students of 92 academic year" and "the survey of after one-year graduated students from 93 academic year" of "Integrated Higher Education Database system", in which a total of 6023 students are included in the sample. It explores the effect of social network, self-concept and academic achievement on the mental health of college students. By using structural equation model, exponent obtained from overall model demonstrates that the model is ideal. Analysis on overall effect demonstrates that social network has significant effect on academic achievement, self-concept and mental health. In addition to direct effect, effect route of social network on mental health is formed by mediating effect of self-concept. It can also be formed by mediating effect of academic achievement and self-concept. Finally, we propose some concrete suggestions for postsecondary education management according to the results.

The growth points of stem point were used as materials to establish the rapid propagation of Kalimeris indica by the studies on the development of growing point,differentiation of adventitious buds,rooting,cutting and transplantation of tube seedling.The results showed that the ideal medium for the growth and differentiation of growth point was MS+BA 0.2 mg·L-1+IAA 0.5 mg·L-1+GA30.5 mg·L-1 and MS+NAA 0.1 mg·L-1+ BA 1.0 mg·L-1,respectively,the ideal medium for root induction culture and successive transfer culture was 1/2MS+IAA 0.6 mg·L-1.Sand was best medium for transplanting to the greenhouse.They grew well when transferred to the hillside.


The potential of 3 Pseudomonas aeriuginosa strains as biocontrol agents of rootinfecting fungi Macrophomina phaseolina, Fusarium solani and Rhizoctonia solani and the root-knot nematode Meloidogyne javanica was tested on chili and uridbean under greenhouse conditions. All the three strains significantly reduced nematode populations in soil, invasion, multiplication and gall formation due to M.javanica . Root infection by fungi was also effectively suppressed following P.aeruginosa application. Bacterial antagonists exhibited better biocontrol and growth promoting activity in 15-day-old plants than did those harvested at 30 or 45 days. Population of the bacterium in the rhizosphere declined rapidly after 15 days of nematode inoculation. Strain Pa-5 showed maximum nodulation in 15-day-old samplings while strain Pa-7 showed highest number of nodules in 30 and 45-day-old uridbean plants.


The hydraulic load presented to the left ventricle by the systemic circulation was characterized by expressing pressure-flow relationships in the ascending aorta as input impedance. This was determined by spectral or Fourier analysis of simultaneously recorded pressure and flow waves in 1 unanesthetized and 27 anesthetized dogs. Impedance modulus fell steeply from its value at zero frequency (the peripheral resistance) and its value was lowest (less than 1/20th of the peripheral resistance) over that band of frequencies (usually between 1.5 and 10 cycle/sec) which contained most of the energy of the left ventricular ejection (flow) wave. The patterns of modulus and phase of ascending aortic impedance were found to result from the presence of two functionally discrete reflecting sites in the systemic circulation, one in the upper part of the body and the other in the lower. The presence of these two sites appears to be an important factor in maintaining a low impedance modulus between 1.5 and 10 cycle/sec, and so in providing a favorable impedance to pulsatile flow from the heart. Both modulus and phase of impedance in the ascending aorta showed changes similar to those seen in other arteries when blood pressure was altered and when vasodilation occurred in the vascular bed.


This paper describes a software package that allows to explore the interior ballistics processes occurring in a shot scheme with bulk charges using propellant pasty substances at various loading schemes, etc. As a mathematical model, a model of a polydisperse mixture of non-deformable particles and a carrier gas phase is used in the quasi-one-dimensional approximation. Writing the equations of the mathematical model allows to use it to describe a broad class of interior ballistics processes. Features of the using approach are illustrated by calculating the ignition period for the charge of tubular propellant.


Model checking is the process of establishing whether a certain formula is satisfied by a given structure, and it is usually associated with point-based temporal logics. Recently, the question of how to correctly define and study the model checking problem for interval-based temporal logics has been raised. In this paper, we focus on a very natural finite version of the model checking problem for Halpern and Shoham's modal logic of time intervals, a.k.a. HS, for which an algorithm that behaves in a very efficient way (under certain conditions) can be designed. We present an implementation of such an algorithm and analyse its performance through a systematic series of tests.
