The Great Lakes represent one of the largest and most significant coastal ecosystems in the world shared by more than one nation. Within the Lake Erie basin, The United States and Canada have cooperated in a number of joint transboundary coastal ecosystem management initiatives. Within the context of this extensive expertise and experience comes the opportunity to examine and reflect upon the ability of public agencies, communities, and citizens to participate and influence decision-making at the transboundary scale. This study focuses on the planning process and results to date from two selected case studies of efforts at transboundary coastal management in the Great Lakes. Each case study clearly demonstrates the challenges and opportunities for transboundary coastal ecosystem management for the Great Lakes basin. Linking science to planning and improving public awareness and education efforts are seen as continual needs in implementing planning actions. Geographic, political, social, cultural and economic differences between the two nations present barriers, which need to be overcome for effective long term and proactive management practices.


Thermoelectric energy conversion is paid attention to as an environmental technology. Research and development has been performed only for inorganic materials for a long time. From a point of view of environmental burden through material life cycle, organic/polymer materials are worthy to be pioneered. Thermoelectric eco-device could be realized by organic/polymer materials. We evaluated thermoelectric properties of typical conductive polymers to expose what are the problems of polymer applications to thermoelectric materials.


The development of new holographic recording materials and the optimization of existing ones is a fundamental field of study, since many of the applications of holography depend directly on the photomaterials properties, as is the case of holographic mirrors, holographic lenses, HUDs as well as augmented reality systems. In this poster we present the results obtained in the optimization of the photochemical process used in the processing of silver halide sensitized gelatin (SHSG). Previous work has shown that excellent results can be obtained in the case of transmission diffraction gratings in BB plates (Colour Holographic Co.), however when the spatial frequency of 3000 l/mm is exceeded, the process is not so good. In the works carried out previously, it has been shown that this photochemical process allows to obtain excellent efficiency values in diffraction efficiency and low level of noise, with excellent spectral sensitivity and energetic sensitivity, but the results that have been obtained in the case of reflection holographic gratings have not been so good, depending on the type of photographic emulsion that has been used as a support. In this work we have made reflection gratings (Denisyuk geometry), using the Color Holographic plate BB640. Given that the gelatin in this plate has a high degree of hardening, we have modified this situation by means of suitable presensitization processes and pH of the developer used. In this way we have achieved good diffraction efficiency results, higher than 80%, and excellent optical quality. Holographic gratings of 5000 l / mm were made, with a He-Ne laser at 633 nm, obtaining a diffraction efficiency of 80%, and a bandwidth of 25 nm., generating a spectral shift of 80 nanometers, due to the Thickness variation during the processing, so it has been possible to obtain excellent reflection filters in the view zone of the visible spectrum. The developer used was AAC, although its composition and pH values have been adjusted to modify the level of differential hardening bias level of the gelatin that supports BB640 plate. These results allow us to make excellent holographic reflection systems, in different areas of the visible spectrum, with good optical quality and sizes that can exceed 10x10 cm2.


Objective To quantify the temporal changes in the volume of blood flow to the skin of the forearm and lower leg during static maximum inspiratory breath-holding of different durations.Methods Blood flow to the skin of the forearm and lower leg were continuously measured with laser Doppler flowmetry in 12 healthy subjects.They were randomly selected to hold their breath for 10,20 or 40 seconds,or as long as possible.The volume of skin blood flow,the onset latency and the recovery latency were measured before,during and after the breath holding.Results Blood flow decreased significantly during each breath-hold with any durations.The magnitude of the decrease and its latencies were similar with all the durations.The average volume of skin blood flow and it's minimum value during each breath-hold were significantly lower in the forearms than in the lower legs.However,the average onset latency (4.41 ±0.44 s) and the average recovery latency (5.95 ±0.59 s) in the forearms were significantly shorter than in the lower legs (4.83 ± 0.70 s for onset and 7.33 ± 0.91 s for recovery).Conclusion The volume of skin blood flow decreases during a static maximum inspiratory breath-hold,and the magnitude of the increase is not related to the duration of the breath-hold.The generalized increase in skin sympathetic vasoconstrictor activity during a static breath-hold is greater in the forearm than in the lower leg.

Key words:
Static breath holding; Laser doppler flowmetry; Sympathetic vasoconstriction; Skin; Blood flow


Here we report the synthesis and superconductivity of (La1-xCex)(O0.9F0.1)FeAs and (La1-xPbx)OFeAs, which were prepared via partially substituting the trivalent La with either Ce in LaO0.9F0.1FeAs or Pb in LaOFeAs, respectively. Influence of the doping level x on the superconducting transition temperatures (Tc) is investigated in correlation with the dopant fraction values in these two sets of superconductors. The accurate existence of the doped Ce or Pb cations inside the typical samples is confirmed by means of electron energy loss spectroscopy (EELS) and energy dispersive X-ray spectroscopy (EDX) measurements. Structural analysis reveals that the increase of Ce content in the samples leads to a systematic shrinkage of the crystal lattice parameters. The observation of superconductivity in (La1- xPbx)OFeAs without F doping indicates a new method for the introduction of charge carriers in this system.


This paper presents a novel method for the detection of the front vehicle and the overtaking vehicle in highway based on active vision.At first,the algorithm detects the marking-line in highway,and locates quickly AOI(Area of Interesting) using the shadow below vehicle from the information of the marking-line in a large scale.Then,it detects fleetly the front vehicle using the symmetry and the edges of the vehicle back view in AOI in a small scale.For the overtaking vehicle,the algorithm sets a detection window on the adjacent lane,and estimates whether an overtaking vehicle exists by the information of the road surface texture.Finally,whether a vehicle appears in AOI is confirmed based on the information of vanishing point and marking line.It is shown that the approach can detect the vehicle quickly and correctly,the algorithm is robust and it meets the demand of the real time system.


4-Amino-1- β - D-ribofuranosyl- s -triazin-2(1 H )-one or azacitidine is a promising DNA demethylation inhibitor used for the treatment of myloneplastic, bone cancer and breast cancer. An efficient, cost-effective and convenient manufacturing process for the synthesis of azacitidine is described. The present research relates to the synthesis, deprotection, isolation and purification of azacitidine ( 1 ). In this process, more particularly 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) is used as deprotection reagent for deprotection of O -acetyl, O benzoyl to acquire azacitidine ( 1 ). The new process allows for the reliable and efficient production of drug substance similar overall yield. The new improved process has merits including enantiomeric purity, better crystallization and the product complies with the requirements of USP30.


This paper considers the current perspective of coordinating efforts to stabilize exchange rates in East Asia, viewed as the first and essential stage of monetary integration process. In this context, the effects of asymmetric demand and supply shocks affecting the two countries are considered, with the help of a game-theory model, and the outcomes from cooperative and non-cooperative fiscal policy responses are analyzed. The properties of fixed-exchange rate arrangements are analytically treated and numerically simulated in a situation where fiscal policies are left as the only device to deal with asymmetric shocks, both on the demand side and the supply side. The model prediction is that both asymmetric demand and supply shocks may be contrasted with the help of fiscal policies, without damaging consequences for the fixed-exchange rate arrangement. The model also suggests that the results will prove better when the fiscal response to the asymmetric shocks is coordinated. Not differently than what happened in Europe following the implementation of end stages of monetary integration, asymmetric fiscal policy response to asymmetric supply shocks may bring about the piling up of huge public debt, and pave the way to sovereign debt crises. Arguably, in such a situation joint fiscal responsibility may help reinforcing the process of integration and convergence.

Magnetization characteristics of electrical machines play a key role for its design and operational performance. Such curves are useful to determine the saturation in the magnetic circuit of the machines in any operating mode i.e motoring or generating. Therefore accurate modeling of such characteristics is essential to determine the performance of electrical machines in steady state and transient conditions. In this paper, the magnetization characteristics of induction machine have been obtained with simulation using linear, polynomial, and exponential techniques. Magnetization characteristics of the induction machine have also been obtained experimentally and the results obtained have been compared with three techniques. The curvefit tool in MATLAB has been employed to find the higher order model with results quite close to the experimental results obtained on the test machines.


A simple and robust technique is reported to offset lock a single semiconductor laser to the atom resonance line with a frequency difference easily adjustable from a few tens of megahertz up to tens of gigahertz. The proposed scheme makes use of the frequency modulation spectroscopy by modulating sidebands of a fiber electro-optic modulator output. The short-term performances of a frequency offset locked semiconductor laser are experimentally demonstrated with the Allan variance of around 3.9×10?11 at a 2 s integration time. This method may have many applications, such as in Raman optics for an atom interferometer.

From doctrine of liability fixation in tort for electric shock of personal injury,we should distinguish between low-voltage and high-voltage electricity. Power companies assume the presumption of negligence liability in the low-voltage electric shock,and in the high-voltage electric shock they assume liability without fault.However,power companies assume liability according to the size of reasons in the case of a variety of reasons,rather than joint and several liability.


Helping students express themselves has always been central to Facing History's mission and curriculum. Writing—exploratory, formal, playful, provocative—helps students to engage self and others and to deepen their understanding about important historical content and themes. Teaching writing will empower you to engage students both with the big ideas of history and with the power of their own minds.

Summary The paper recounts the experience of a cycle of film showings organized by the students themselves, which was also recognized as being an activity whereby elective credits could be obtained. The activity was carried out during the 2009-10 academic year in the Biology degree at the Pompeu Fabra University (UPF) in Barcelona. The organization of the activity and the assessment of the students enrolled were undertaken by the Student Organizers under the supervision of the Dean of the Faculty of Health and Life Sciences. The experience was deemed to be highly successful for the following reasons: the number of students enrolled on it, the notable participation and the result of the assessment of the reports handed in by the students. The activity could be considered a good example of students' involvement in their own training, both technical and human.


Since there will always be model uncertainty and disturbance acting on the system, they should be considered in the controller design. In this paper, both uncertain time-varying parameter and bounded additive disturbance are explicitly taken into account in the MPC formulation. Robust stability and constraint satisfaction are guaranteed by computing a positively invariant set containing the measured state at each sampling instant. This article is organized as follows. In Section II, the problem statement is presented. In Section III, robust MPC synthesis is proposed. In Section IV, the effectiveness of the proposed MPC algorithm is illustrated by a simulation example. Finally, the conclusions are drawn in Section V. Notation: For a vector x and a positive-definite matrix P , Px x


We find the Gutzwiller projected Fermi sea wave function(GWF) has the correct phase structure to describe the kink nature of the doped holes in the ground state of the one dimensional t − J model. We find the failure of the GWF for general value of J/t and electron density n can be attributed to the residual charge correlation in the ground state. We find such residual charge correlation is well described by a XXZ-type effective Hamiltonian. Based on these observations, a Pfaffian-type variational wave function is proposed and is found to reproduce correctly the global phase diagram and corresponding correlation functions of the one dimensional t−J model, including the Luther-Emery phase in the low electron density and large J/t region.


The feasibility of direct utilization of bamboo biochar (BC) as a fuel for solid oxide fuel cells (SOFCs) is studied by comparing BC to de-ashed BC (DC) and activated BC (AC) in terms of Boudouard reactivity and the performance of the fuel cell. The CO partial pressures in the carbon dioxide temperature-programmed oxidation profiles of BC and DC are 3.18 × 10–8 and 1.04 × 10–8 Torr at 850 °C, respectively, which indicates that BC has superior Boudouard reactivity compared to DC. The peak power densities (PPDs) of the cells fueled with BC and DC are 121 and 73 mW cm–2 at 850 °C, respectively. The inherent metal elements in BC, mainly K of 33.88 mg g–1 and Ca of 2.06 mg g–1, play a key role in boosting its Boudouard reactivity and the performance of the cell. In addition, the loading of artificial catalysts to BC can noticeably enhance its Boudouard reactivity and gain a higher power output of the cell fed with it. The PPD of catalyst-loaded BC achieves approximately 191 mW cm–2 at 850 °C. This study reveal...

Anthracyclines are highly effective chemotherapy drugs. However, their use is associated with anthracycline cardiotoxicity (AC), which may result in premature heart failure. Risk of AC is related to cumulative dose, but is also highly idiosyncratic. Effective tests to predict susceptibility are lacking: serial measurement of left ventricular ejection fraction (LVEF) detects cardiotoxicity only after significant damage has occurred. I hypothesised that: (i) Genetic variation underlies susceptibility to cAC. (ii) Risk of cAC could be predicted after the 1st dose of anthracycline by measuring oxidative stress (urinary F2-Isoprostanes, uF2IP), and (iii) also by cardiovascular magnetic resonance imaging (CMR) tissue characterisation (EGRE and STIR). I tested these hypotheses in a prospective gene-environment interaction study, whereby 164 women underwent measurement of LVEF, before and >12 months after anthracyclinechemotherapy. Sixty subjects participated in the 1st dose sub-studies. The mean change in LVEF at follow-up (ĢLVEF) was -2.2%. Thirty-four subjects (20.7%) experienced a fall in LVEF .5% (the cAC group). LVEF fell by 0.8% in the remaining 130 (minimally affected controls). An a priori tiered genetic analysis was performed. High probability variants (Tier 1) were identified (i) by cross referencing human GWAS and gene-expression / proteomic data from animal models of AC (N=12) (ii) from associations with AC reported by others (N=4). Significant associations were discovered with CLCNKA rs10927887 (OR 4.7 [2.1-10.5]) and PDE4D rs1588265 (OR 3.3 [1.51-7.37]), p=0.003 and p=0.045 respectively (Bonferroni corrected). There were correlations between ĢLVEF and percentage change in uF2IP (r=0.30, p=0.04), EGRE (r=-0.35, p=0.01) and STIR (r=-0.29, p=0.03). My results support all 3 hypotheses, and suggest that it may be possible to develop tests to identify individuals at increased risk of cAC and premature heart failure before the majority of the damage is caused. Recognition of this susceptibility could inform treatment decisions and /or identify those requiring greater cardiac surveillance.


Introduction. This article describes the feedback between the Soviet people and executive authorities of the autonomous republics from the mid-1950s to the 1980s on the example of activities of the Councils of Ministers of the Mari, Mordovian and Chuvash Autonomous Soviet Socialist Republics. The research focuses on the reaction of the Councils of Ministers and their subordinate bodies to letters, received from citizens.

Materials and Methods. The study was based on materials of the State Archive of the Republic of Mari El, the State Historical Archive of the Chuvash Republic, and the Central State Archive of the Republic of Mordovia. In the work were used the content analysis, the concrete historical, the historical-systematic and the historical-comparative methods based on the on the fundamental principles of historical study – historicism, objectivity, systemacity.

Results. The most common form of everyday communication between the Councils of Ministers of ASSR and the society was the submission by citizens of applications, appeals and petitions, which raised the various issues. The analysis of the activities of the Councils of Ministers of the Autonomous Republics revealed problems related with the consideration of citizens' appeals. The reaction of the Councils of Ministers to criticism of shortcomings in the organization of accounting for incoming letters, control of subordinate authorities, as well as the personal reception of citizens is considered. The most pressing issues with which Soviet people appealed to regional governments were identified.

Discussion and Conclusions. Despite significant shortcomings in the system of consideration of complaints and appeals of citizens, the Councils of Ministers, as the central bodies of state administration of the republics, as a whole performed a number of important communicative functions between the government and society. The following are the most basic points: 1) the citizens had the opportunity to solve various everyday, social, economic issues using the appeal to the authorities; 2) the regional authorities received representations about the problems of concern to the Soviet people, so that timely action could be taken; 3) Councils of Ministers of ASSR and subordinate bodies acted as a link between the people "on the ground" and the highest authorities.


The continuous wavelet transform calculator is the basis of the algorithms for automatic analysis of biomedical signals. The use of such systems is justified in conditions of isolation, also from large medical institutions. The device developed in this project is designed to operate in ultra-low temperatures and is designed to operate in the Arctic and Antarctic regions. The continuous wavelet transform calculator is implemented on an elemental base with ultra-low power consumption and can operate for 16 hours 40 minutes 12 seconds from an autonomous power source (excluding losses).


India has severe problem of road traffic congestion in the metros. This paper focuses on improving the Vehicular Traffic Efficiency using Static Sensing Method with Dynamic Signal Periods and Cost-Effective Technique (CET). In this paper, we have shown how IR sensors can be used to improve efficiency, both cost-wise and operation wise, for the vehicular traffic system. Further, we have implemented the algorithm for both closed-loop and open-loop systems and compared the results. We have also made a small scale model for one square with four lanes powered by Arduino UNO to have a clear picture of how the proposed system will work.


The TELEMED-Project R0186, being funded under the RACE III European Community cooperative programme, will establish an extensive working communication network between widely dispersed medical experts and medical data resources within Europe until the end of 1992. The overall objective of the TELEMED-Project is to examine the problems which arise when participating physicians communicate over IBCN. The features and requirements specified are analysed in particular, so that an overall cooperative diagnosis and therapy can be realized as an application pilot now. In addition, the consequences of the corresponding organisation and operation of these services on the clinic work, legal, ethical and administrative issues must be examined.


The oceanographical conditions in December in a sea area east of Kinkazan, 38•K20'N, 141•K30'E, are stated for the three years 1950 to 1952, and the characters of the water masses in the sea are analysed from the investigation of plankton. Kuroshio Region (observing stations A3, A4, B3, B4, C3 and C4)-A water mass of higher temperature and chlorinity, namely Kuroshio water, appears every year in the sea area from 144•‹ to 145°E and its vicinity. Warm-water diatom species are abundant, and it is noticeable that Trichodesmium Thiebauti, a tropical blue algae, was detected in this water mass alone. The similarity of the paths of the Kuroshio in the past three winters is suggested by the fact that the diatom communities are resembling to each other at the six stations mentioned above. Oyashio Region (stations A5, A6, A7, B5 and CS) •\he Oyashio water of lower temperature and chlorinity exists in the east of 146°E, but the difference of water characters in respect to the years and stations is shown by the remarkable fluctuation of planktological conditions. In general, Chaetoceros decipiens, a north temperate species, is dominant. Neritic Region (stations Bl, B2, Cl and C2)-In the sea area west of 143•‹E, the water is rich in neritic species, especially in 1952 in Chaetoceros debilis, a typical neritic and cold water species. An enclosed water mass of the temperatures lower than 7•‹C at the layer of 75-meter depth at st. B2 shows a significant connection with the existence of Chaetoceros atlanticus, a boreal species.


In this paper, we present an approach for Recurrent Iterative Gating called RIGNet. The core elements of RIGNet involve recurrent connections that control the flow of information in neural networks in a top-down manner, and different variants on the core structure are considered. The iterative nature of this mechanism allows for gating to spread in both spatial extent and feature space. This is revealed to be a powerful mechanism with broad compatibility with common existing networks. Analysis shows how gating interacts with different network characteristics, and we also show that more shallow networks with gating may be made to perform better than much deeper networks that do not include RIGNet modules.


The study on Hydrogenated fat replaced with peanut butter to reduce saturated fatty acids in cookies was carried out. Cookies prepared with varied concentrations of hydrogenated fat and peanut butter (100:00, 80:20, 60:40, 40:60, 20:80 and 00:100) were analyzed to check fatty acid composition and textural characteristics. Palmitic acid, Myristic acid and Stearic acid (Saturated fatty acids) were higher in Control cookies, which level was reduced with increasing concentration of PB in different treatments. Linoleic acid and Oleic acid (Unsaturated fatty acids) were lower in control cookies, which were increased with increasing concentration of Peanut butter in different treatments. Oil stability index of experimental cookies increased up to 3.62% with increasing concentration of PB. Cookies hardness was also increased with increasing concentration of PB. Cookies with 40% PB had beneficial fatty acid composition with stable oil quality and also had a greater appreciable sensory quality by evaluation panel.

It has been noted in prior papers that schemes of arrangements, in the last decade, are being used more as a device for achieving control, as a genuine alternative to a formal takeover bid. This is generally attributed to schemes being a more flexible transactional model. This article reviews the legal commentary on the advantages and disadvantages of schemes, and follows this through with a survey of practitioner attitudes and experience with using schemes. The practitioner survey reinforces the perception that schemes are 'friendlier'. By pinpointing the qualitative characteristics of schemes and by providing some quantitative measures of the deal and of scheme participants, this article discusses the connotations of friendliness. This descriptive data show that scheme target shareholders generally earn less than on average in bid premium than bids and that scheme success is less dependent on the magnitude of any pre-bid stake the bidder may hold in the target prior to the scheme, than in a bid.


Abstract Kathy's 1st-person narrative in Kazuo Ishiguro's Never Let Me Go depicts the relationships among three leading characters, Kathy, Ruth and Tommy, who live in a near-contemporary world, where (we slowly grasp) some human clones are raised to be a source of replacement organs for non-cloned humans in ill health. Kathy and her friends are three such clones. Figurative expressions in Kathy's narrative tend to appear in the form of similes or with explicit markers of similitude such as 'like' and 'the sort', and the frequency of 'like' is particularly high. The primary focus of this paper is to examine the effects which are achieved by 'like'-similes and how they contribute to constructing the fictional world of the novel. 'Like' is used here with syntactic flexibility and semantic versatility and these 'like'-similes are predominantly used to describe the characters' actions, intentions, emotions and the situations in which they act. As the three friends grow older and approach the final phase of their lives, when they will be organ donors, the characters' viewpoints and the narrator's presentation of them shift. Through an array of 'like'-similes, the 1st-person narrator consistently interprets other characters' internal states and signals the way she is making assumptions about them and the surrounding environments.


This master's project deals with analysis of the Czech and Slovak state documents for primary education in relation to the teaching of spreadsheet programs. The result of this analysis was that the documents are not specific enough. Therefore, we have proposed own goals for teaching spreadsheet programs in elementary schools.
At selected schools from the Czech and Slovak Republics this master's project analyzes school educational programs in relation to teaching of spreadsheet programs. Schools having regard to distribution of population in villages according to the population were selected to create a representative sample size of 1.5%. The selection of specific schools was made at random.

In the tasks there are always available two versions of the file, both for work in the program Calc and Excel spreadsheet.
This work is a preview of the current status of description of teaching spreadsheets in state school documents compared to the optimal description. The main contribution of this work is to support the teaching of spreadsheets in elementary schools. And both in the theoretical level of description of range of teaching spreadsheets, as well in practical sets of specific examples.


Abstract : The Advanced Degree Requirements Information System (ADRIS), an interactive computer-based data retrieval system, was updated, validated, optimized, and documented. ADRIS was implemented for use by noncomputer oriented Air Force Institute of Technology faculty and staff at time-sharing terminals. The ADRIS Inventory and Requirements data bases can be queried for information about Air Force graduate degree officers and Advanced Academic Degree job positions. The ADRIS system was analyzed, tested, and altered to insure correct operation and reliable output reports. A successful validation effort was conducted with the Air Force Data Services Center using two separately developed computer programs to compare results.


Facing the fact of the heavy mental pollutions in soil in Hulu Dao mining area,which caused by mining actions from numbers of Molybdenum mines,a regional study was conducted.Firstly,60 soil samples from orchards and 20 fruit samples from each of Fuji apple,Bai pear and Jinfeng Pear were collected.Secondly,the samples were dissolved before being examined.Following that,an ICP-AES was used for determining the levels of Pb、Ni、Cu、Cr、Zn、Cd、As、Mo、Hg.At the same time,the concentration of heavy mental was measured.According to the results,the pollution of Cd,As and Hg in soil is serious,moreover,Pb,Ni,Cu,Cr and Zn are also over the standard.The amount of varies heavy mental are:CdAsHgPbZnCrCuNi.Accordingly,the heavy mental pollution in soil will affect fruiters in this area.Simultaneously,the quality of fruits will deteriorate.


Forming of metals in their semi-solid state is one of the options for producing near net shape parts. It can produce a strong and highly reliable product. Al-Si-Cu-Mg casting alloy is commonly used in automotive engine components which is now widely used in the semi-solid processing. The main physical properties of the aluminium alloy and alloying element content such as silicon, copper and magnesium, plays an important role in determining the mechanical properties of the alloy. In this paper, the effect of the formation process of Al-Si-Cu-Mg permanent die casting alloy and the thixoforming process has been investigated towards the evolution of microstructure and mechanical properties. Compound phases, shapes and morphology of the two processes were compared. The porosity effect was examined at permanent die castings and thixoforming process. The result of image analysis showed significant change of the thixoforming process of α-aluminum solid phase structure in spherical shape. Size and morphology, as well as the uniformity of the silicon eutectic phases and intermetallic compound distributions of Al2Cu, Al5Fe Si and Al15(Mn,Fe)3Si2 changed due to the compression during thixoforming process. Thixoforming process of the Al-Si-Cu-Mg alloy exhibit the lowest percentage and microporosity area thus proved that porosity issue significantly reduced during the aluminium alloy solidification process in thixoforming process . The tensile properties of thixoformed alloy improved significantly with its ultimate tensile strength, yield strength, and elongation to fracture at 193MPa, 163MPa and 1.6%,respectively.


The Ghana Atomic Energy Commission (GAEC) commercialises irradiation sterilisation since 2010. Capacity-building using a 'systems thinking' approach during series of stakeholder workshops and interviews has shown a remarkable impact on factors influencing adoption, and challenges involved in irradiation sterilisation. Results indicated that the adoption of irradiation sterilisation increases as end-users acquired knowledge about its efficiency. However, the benefits of optimising the adoption of irradiation sterilisation are in direct conflict with more demand leading to 'waiting in lines', creating resistance to complete confirmation. To increase the utilisation of the facility, GAEC must adopt a more interactive system to avoid queueing. This paper demonstrates the practical approach of 'systems thinking' using the evolutionary learning laboratory for marketing practices, monitoring and evaluation to replace old business marketing and management models. With regard to the important contribution irradiation can have on the improvement of public health, it may usher a greater potential for investors.


The aim of this paper is to provide guidelines for developing high-quality, well-written GNSS software receivers. The systematic application of software design patterns and programming methodologies speeds up the development process by providing tested, proven development paradigms, and improved code readability for coders, receiver architects, and users. This includes unit testing of all the modules, and the use of a code programming style stressing readability and language-specific conventions. All these good practices result in fewer bugs, reduce reinvention-of-the-wheel, and cut long-term maintenance costs. The paper provides an analysis of design patters, good coding practices, and methodologies for the design and implementation of GNSS software receivers, describing a working implementation released under the GNU General Public License.


Individuals with traumatic brain injury (TBI) have been shown to have high prevalence rates of depression. Reward processing and motivational deficits have been shown to be associated with depression, since both constructs rely on the ffonto-striatal network. In this study, we examined depressive symptomology, motivational tendencies and striatal activation during wins and losses in individuals with TBI. Participants (TBI and healthy controls [HC]) completed a gambling task composed of wins and losses in an MRI scanner. Depressive symptomology was assessed with the Chicago Multiscale Depression Inventory (CMDI), while motivational tendencies were assessed with the Behavioral Inhibition/Behavioral Activation (BIS/BAS) scale. Significant between-group differences were observed in BAS (p=.01), BASDrive (p = 0.003), BAS-Reward Responsiveness (p = 0.04) and in all CMDI subscales (Mood: p = .01; Evaluative: p = 0.02; Vegetative: p = .001), with significant correlations seen between both questionnaires. Using VBM analysis and the segmentation of subcortical structures, a significant GM decrease in both the right ACC and bilateral NAcc was seen in the TBI group. A positive correlation was found in the TBI group between the CMDI-Mood subscale and activation of the left NAcc during loss trials (r = -.858, p < 0.05), while a strong negative correlation in the TBI group was found between BIS and activation of the right NAcc during win trials (r = -.852, p < 0.05). When split between high and low BIS scores, the TBI group scoring higher on BIS showed significantly lower levels of NAcc activation during win trials (p < 0.05). No demographic between-group differences were detected. The current study replicates previous evidence in non-TBI individuals with depression, as well as provides pioneering evidence on the existence of the association between striatal engagement in depressive symptomology and motivation in individuals with TBI.

The crystal structures of natural liebenbergite{Ni1.52Coe.e5Fee6eMgo.ra)SiOa-from Barberton, South Africa, and of synthetic liebenbergite-{Ni' 'uMg.6a)SiOo-synthesized at 500oC, have been studied in order to determine the intracrystalline Ni-Mg distribution. The natural liebenbergite is fully ordered, with Ml occupied only by Ni, whereas the synthetic sample is only partialy ordered with Ko : [Mg(M2)'Ni(Ml)/[Ni(M2)'Mg(Ml)] : 9.9(a), AG& : -3.5 kcafmole. Comparison with the results of Rajamani et al. (1975), who found K":9.2(2) and AG& : -6.9 kcal,/mole for a sample synthesized at l280oC, implies that the 500oC synthetic sample in the present study crystallized metastably in a disordered or partially ordered state and ordering proceeded slowly. Although site size effects are small in Fe-Mg, Ni-Mg, and Co-Mg olivines, the crystal field stabilization energy is important in determining the observed cation distribution in Ni-Mg and Co-Mg olivines. Electronegativity or covalency effects are known only qualitatively, but there is a preference of less electronegative ions (Mg, Ca) for M2. Ordering of Ni into the Ml site of olivine should appreciably afect Ni partitioning between olivine and melt, and activity-composition relations have been examined assuming ideal solution behavior. Deviations from Raoult's law increase with increasing order, but variations in activity coefficients are less than l0 percent below l0 moleTa Ni.


Output power of a fuel cell (FC) stack can be controlled through operating parameters (current, temperature, etc.) and is impacted by ageing and degradation. However, designing a complete FC model which includes the whole physical phenomena is very difficult owing to its multivariate nature. Hence, online identification of a FC model, which serves as a basis for global energy management of a fuel cell vehicle (FCV), is considerably important. In this paper, two well‐known recursive algorithms are compared for online estimation of a multi‐input semi‐empirical FC model parameters. In this respect, firstly, a semi‐empirical FC model is selected to reach a satisfactory compromise between computational time and physical meaning. Subsequently, the algorithms are explained and implemented to identify the parameters of the model. Finally, experimental results achieved by the algorithms are discussed and their robustness is investigated. The ultimate results of this experimental study indicate that the employed algorithms are highly applicable in coping with the problem of FC output power alteration, due to the uncertainties caused by degradation and operation condition variations, and these results can be utilized for designing a global energy management strategy in a FCV.


The problem of calculating comprehensive sets of cross sections for ionization of atoms and molecules is reviewed. Emphasis is put on targets that are already ionized and lower-energy collisions for which the incident electron must be treated on a par with target electrons. The physical circumstances are discussed in which perturbation methods should be adequate, and special investigations are recommended to identify the relevant ranges of parameters more precisely and dependably. A new R-matrix approach is outlined which should permit rather simple, approximate, but dependable calculations when the perturbation methods fail.


This telepathology study was designed to evaluate several parameters like the specific need for telepathology, practical equipment handling, image quality and acceptance of a static imaging system for consultations between pathologists. The study shows that the most highlighted medical need for telepathology in Sweden involve diagnostic questions about: cancers in general, grade of malignancy, malignancy of soft tissue, haematopoetic system, skeletal system, breast, uro-genital systems and in the field of dermatology, inflammations and transplantations. A static-image transfer system was used but the assessment clearly shows that pathologists prefer a dynamic imaging telepathology system for the future.


Water is a critical element of electric power production in the U.S., particularly in the Great Lakes Basin region. Thermoelectric power generation accounts for the majority of all water withdrawals in the Basin, in large part due to the comparatively heavy concentrations of coal and nuclear power generation that utilize open-loop cooling. This paper explores how different energy generation portfolios could affect the water resources of the Great Lakes Basin. The suite of power generation scenarios analyzed reflects a range of potential outcomes resulting from the implementation of key national and regional energy and environmental policies for the electric power industry. These policies include U.S. EPA's pending power plant cooling water intake standards, state renewable energy portfolio standards,  possible climate change legislation, and the 2005 Great Lakes regional water resource agreement (Great Lakes and St. Lawrence River Basin Water Resources Compact of 2005; Public Law 110–342).  Five scenarios were analyzed, resulting in different levels and intensities of total water use (withdrawal and consumption) in hydrologically-sensitive watersheds. These results confirm the close relationship between water and energy in the Great Lakes, and point to the need to take into account water resource impacts in designing future energy and environmental policies.

This journal examines the implementation of the National Education System Law Number 20 of 2003 concerning the Right to Get Islamic Religious Education in State Elementary Schools in North Minahasa. The main problem is to know the standardization for implementing Islamic religious education services at two elementary schools (SDN Suwaan and SD Inpres Kawangkoan) and to find out the realization of the right to receive Islamic religious education, mainly in Kalawat District, North Minahasa Regency. This research is field research, using descriptive qualitative research methods with data collection techniques, namely observation, interviews, and documentation. The findings of this study indicate that the standardization of implementing Islamic religious education services at those two schools is to pay attention to the presence or number of students who are Muslim, namely with a minimum ratio of 15 students in one class or in one school as stated in the Regulations. Therefore, the realization of the right to obtain Islamic religious education based on the National Education System Law no. 20 of 2003 at these schools could be realized as it should be. This is because students have not received religious education taught by educators of the same religion because of the unavailability of Islamic religious educators, so that the law has not been implemented properly.


Collaborative simulation technology faces one primary problem that how are simulation component models in virtual prototype engineering of complex production developed and published effectively so as to be helpful for product designers to discover and access these simulation resources distributed in collaborative manufacture network environment easily.

Deserts are the major source of the dust greatly impact the biogeochemical cycles. However, quantitatively evaluating iron forms in the dust source areas is still a challenge due to large uncertainty in the iron mineralogy. Here we investigate iron mineralogy of 19 surface sand samples collected from seven deserts along the arid zone in North China and Mongolia. By use of a Mineral Liberation Analyzer (MLA) technique, we show that the iron mineral assemblages include a total of 38 mineral phases. In particular, chlorite and hornblende contribute 50-60% iron content of in the Chinese deserts along the metamorphic mountain belts of Northern Tibetan Plateau (NTP). The newly uplifted and strongly erosive mountain provides easily-deducible chlorite and hornblende, and filled the Chinese deserts as sediments. This region has much higher iron content relative to Mongolia Gobi. This finding suggests that the active mountain belts mentioned above are of great importance of dust input in iron. Further analyses of the iron content in particle size distribution suggest that the desert sourced dust tended to decrease the initial iron content originated from the mountain belts, considering the size reduction during the transport. Based on the spatial variation of the iron content, combined with the dust flux in each desert, we estimated the upper limit for the atmospheric iron influx. Our estimation provides a basis for assessing the marine "biological pump" effect, that causing fundamental changes in the atmospheric CO2 level.


We characterise the bracketing identities satisfied by linear quasigroups with the help of certain equivalence relations on binary trees that are based on the left and right depths of the leaves modulo some integers. The numbers of equivalence classes of $n$-leaf binary trees are variants of the Catalan numbers, and they form the associative spectrum (a kind of measure of non-associativity) of a quasigroup.

Abstract This paper studies the topic of optimal investment in physical capital and R&D in the context of a valuation model, which is a particular version of the Gordon growth model. The proposed valuation model adjusts the Gordon model in two respects. First, it distinguishes between R&D investments and investments in physical capital and shows that the two have distinct optimality conditions. Second, it shows that externalities have implications for a bound from above on the relevant hurdle rate for R&D investments and for the way in which returns on R&D investments are reconciled with returns on financial assets.


This paper presents a method for the on-chip measurement and correction of gain errors, offsets and time-skew errors in time-interleaved ADC's. With the proposed method, the errors can be measured and processed in the digital domain. Then, this information is used to optimize several digitally controlled analog parameters of the circuit, that minimize the effect of aforementioned mismatch errors. After optimization, the digital logic can be switched off completely in order to save power. Simulation results on a full-transistor implementation of the time-interleaved sampling structure show that the channel matching errors can be accurately compensated.


Purpose: This study aims to describe an efficacious method using Cleaner XT rotational thrombectomy with catheter-directed thrombolysis and drug-eluting balloon angioplasty for the salvage of thrombosed arteriovenous fistulae and grafts. Materials and Methods: Retrospective analysis of all patients with thrombosed hemodialysis accesses who underwent endovascular salvage using the Cleaner XT rotational thrombectomy system at a single institution between June 2019 and September 2020 was performed. Patency was presented as Kaplan-Meier survival curves, and regression analysis was performed to examine predictors of postintervention primary patency and assisted primary patency based on Cox proportional-hazards model. Results: Thirty-four patients with thrombosed accesses underwent Cleaner XT rotational thrombectomy between June 2019 and September 2020. Technical and clinical success were both 100%. Mean procedure time was 62 ± 20 minutes. Mean postintervention primary patency time was 152 ± 51 days; 30, 90, 180, and 365 day postintervention primary patency rates were 89%, 80%, 68%, and 56%, respectively. Mean postintervention-assisted primary patency time was 157 ± 59 days; 30, 90, 180, and 365 day postintervention-assisted primary patency rates were 91%, 82%, 71%, and 59%, and 180 and 365 day secondary patency rates were 97.2% and 94.4%, respectively. Conclusion: The Cleaner XT rotational thrombectomy device demonstrates excellent clinical and technical success rates, with good patency results at all time points up to 12 months postintervention.

In the scientific process, the proper equipment is essential for collecting quality data. This project was to design and fabricate the fixturing for use in experiments to determine the effects of surface roughness on the carburization of steel alloys. Potential contaminates on the test samples were removed using a self contained cleaning system. Afterword the samples were carefully transported and attached to a carburizing fixture of unique design. This fixture was designed and manufactured to be compatible with preexisting commercial equipment and tested to withstand the stresses of the carburization process. The carburizing cycle completed without failure, the samples were removed and successfully prepared for analysis.


The adaptive radiations of African cichlids resulted in a diversity of feeding morphologies and 19 strategies, but the role of sensory biology in prey detection and feeding ecology remains largely 20 unexplored. Two endemic Lake Malawi cichlid genera, Tramitichromis and Aulonocara , feed on 21 benthic invertebrates, but differ in lateral line morphology (narrow and widened lateral line 22 canals, respectively) and foraging strategy. The hypothesis that they use their lateral line systems 23 differently was tested by looking at the relative contribution of the lateral line system and vision 24 in prey detection by Tramitichromis sp. and comparing results to those from a complementary 25 study using A. stuartgranti (Schwalbe et al., 2012). First, behavioral trials were used to assess the 26 ability of Tramitichromis sp. to detect live (mobile) and dead (immobile) benthic prey under 27 light and dark conditions. Second, trials were run before, immediately after, and several weeks 28 after chemical ablation of the lateral line system to determine its role in feeding behavior. Results 29 show that Tramitichromis is a visual predator that neither locates prey in the dark, nor depends 30 on lateral line input for prey detection and is thus distinct from A. stuartgranti , which uses its 31 lateral line or a combination of vision and lateral line to detect prey depending on light condition. Investigating how functionally distinctive differences in sensory morphology are correlated with feeding behavior in the laboratory and determining the role of sensory systems in feeding ecology will provide insights into how sensory capabilities may contribute to trophic niche segregation.


To what extent can Czech exporters cushion the impact of currency appreciation shocks by using imported intermediates? We apply a partial equilibrium model with firms that are heterogeneous in their productivities. Producers can serve the domestic market, export final goods, or import inputs. In the model, an exogenous exchange rate shock simultaneously affects the variable costs and revenues associated with exports and imports. The impact of a hypothetical 1% appreciation of the domestic currency on sales is estimated using a panel of 7,356 Czech manufacturing firms observed from 2003 to 2006. We identify the estimates from within-firm variation in trade strategies, which is probably associated with the lifting of trade barriers due to Czech EU membership since 2004. For firms that both export and import, we predict a drop in total sales of 0.2%, a drop in export sales of 0.8%, and a rise in domestic sales of 0.2%.


Background Effective community mitigation through voluntary behavior change is currently the best way to reduce mortality caused by coronavirus disease (COVID-19). This study builds on our prior study based on the scientific premise that YouTube is one of the most effective ways to communicate and mobilize the public in community mitigation to reduce exposure to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Objective Because of the rapidly changing nature of YouTube in the context of the COVID-19 pandemic, we conducted a follow-up study to document how coverage of preventive behaviors for effective community mitigation has changed. Methods A successive sampling design was used to compare coverage of behaviors to mitigate community transmission of COVID-19 in the 100 most widely viewed YouTube videos in January 2020 and March 2020. Results Videos in the January and March samples were viewed >125 million times and >355 million times, respectively. Fewer than half of the videos in either sample covered any of the prevention behaviors recommended by the US Centers for Disease Control and Prevention, but many covered key prevention behaviors and were very widely viewed. There were no videos uploaded by entertainment television in the January sample, but this source comprised the majority of videos and garnered the majority of cumulative views in the March sample. Conclusions This study demonstrates the incredible reach of YouTube and the potential value of partnership with the entertainment industry for communicating and mobilizing the public about community mitigation to reduce mortality from the COVID-19 viral pandemic.

Modular UPS are usually presented as having an extremely high level of availability. In fact, the best modular UPS systems are designed to increase the global system's availability with minimum downtime due to their hot-swappable parts and cost-effective redundancy, the complete independence of each module and no fault propagation if one of the modules fails. However, the biggest concern is the internal reliability of UPS systems owing to the use of many modules. This paper explains and quantifies this issue and describes how to handle it, proposing design rules to significantly increase the modules' MTBF and giving a method for calculating and verifying it.


Translational control is an important aspect of the regulation of gene expression in eukaryotic cells. In addition to the translating pool of mRNA associated with polysomes, recent experiments have defined cytoplasmic foci, referred to as P bodies, wherein untranslated mRNAs accumulate and where mRNA decapping and decay can occur. We now present several lines of evidence that yeast mRNAs within P‐bodies can also return to translation. For example, reporter mRNAs exit translation and concentrate in P‐bodies when translation initiation is blocked, and resume translation and exit P‐bodies when translation is restored. These results define a cycle of mRNA movement wherein mRNAs travel from polysomes to P‐bodies and then back to the translating pool. This mRNA cycle has several important properties and identifies three critical decision points in controlling the function of mRNAs: 1) the mechanism of targeting transcripts to P‐bodies, 2) deciding the fate of transcripts within P‐bodies, and 3) the mechanism by which transcripts return to translation. Additional experiments show that accumulation of mRNAs in P‐bodies is required for global translation repression. This suggests that translation repression by sequestration into P‐bodies is competitively balanced with translation and shifts in this balance play a role in translational control.


The causes of distortion of the laser beam as it passes through the atmospheric channel are presented. It is shown that for industrial lasers used for cutting of materials, beam spreading reduces the density of the power distribution across the beam, which changes the nature of radiation interaction with the processed surface. Control by density distribution over the cross section of the radiation beam is an actual problem that improves the quality of processing of the material and reduces the required energy. It is noted that the control system of the laser power density distribution containing matrix power meter with thermoelectric coolers, thermal control receivers when measure high radiation intensities, have significantly lower values of reliability, since the failure rate depends on the thermal load and decreases by orders of magnitude compared to rated load. Failure of the matrix element leads to the formation of incorrect control to the executive body of the change in the shape of the laser beam. It is analyzed an approach to increase the viability of the matrix thermally loaded detector based on the dependence of the response elements of the matrix and its environment, that allow to ensure the correct reaction of control system in case of failure of the elements of perception of input information. The model means providing a visual representation of the results are developed. It is shown that the information methods can improve the viability of the system.


Polycentricity has an extensive and complex meaning that diverges depending on the spatial, social, economic and historical perspective of the research. This complexity generates multiple definitions of this subject, since the context in which an urban polycentric system is situated influences its profile, providing an unclear explanation of this notion. This paper examines theconception of polycentrism in its larger sense, reviewing the literature. This theoretical framework presents the theme in a comprehensive way, seeking a general definition for the context of Brazilian metropolis. The article also looks into the polycentrism relevance in the country's context, classifying the Brazilian urban areas into Medium-Sized City, Metropolitan Region, and Inter-Metropolitan Region. These typologies are characterized in order to build a useful definition of polycentrism in the Brazilian context.


Although nanobiotechnology may be an invaluable tool in revolutionising contemporary medicine, our understanding of "nanobio"-related risks/benefits ratio is still very limited. Despite the increasing investments and support, the comprehensive scientific evaluation of this technology has not yet been carried out, thus its full effect on humans and environment remains undiscovered. In the last few years legislators have shown some willingness to address the problems of nanobiotechnology risk regulation specifically, but this process is still at the development stage. Meanwhile, public "nanobio-awareness", hence, reception of this technology has not changed significantly over the last decade. Overall, education and further research are deemed to be the best instruments to help shape an adequate public and regulatory approach.


The purification of cytidine triphosphate(CTP) by ion-exchange chromatography was studied. Anionion-exchange resin 201×7 was selected from four different resins and eluted successively by 0.4mol/L and 1mol/L sodiumhydroxide solution with discrete method of gradient elution. A HPLC method was established for determination of CTP.A WAX-1 column was used with the mobile phase of 480mmol/L phosphate buffer(pH6.0). The detection wavelength was260nm and the column temperature was 35℃. The content of CTP in final product was 75%.


The metasurface-based superoscillatory lens has been demonstrated to be effective in finely tailoring the wavefront of light to generate focal spots beyond the diffraction limit in the far-field that is capable of improving the resolution of the imaging system. In this paper, an ultra-thin (0.055 λ 0) metasurface-based superoscillatory lens (SOL) that can generate a sub-diffraction optical needle with a long focal depth is proposed, which is constructed by ultra-thin chiral unit cells containing two metal split-ring resonators (SRR) with a 90° twisted angle difference cladded on both sides of a 1.5 mm-thick dielectric substrate, with a high linear cross-polarized transmission coefficient around 0.9 and full phase control capability at 11 GHz. Full-wave simulation shows that SOL generates a sub-diffraction optical needle within 10.5–11.5 GHz. At the center frequency, the focal depth is 281 mm (10.3 λ 0) within 105–386 mm, the full width at half maximum (FWHM) is 18.5 mm (0.68 λ 0), about 0.7 times the diffraction limit, generally consistent with the theoretical result. The proposed ultra-thin chiral metasurface-based SOL holds great potential in integrating into practical imaging applications for its simple fabrication, high efficiency, and low-profile advantages.

Radiographic studies of 26 choledochal cyst patients were evaluated. Abnormal junction of the pancreatico-biliary system (PBS) was demonstrated in all patients. The transverse diameter of dilated common bile ducts was closely related to the length of the narrow segment of the distal common bile duct. Common bile ducts had not dilated despite the anomalous junction of PBS during the follow-up period, ranging from 2 to 12 years after choledochocysto -jejunostomy in 7 patients. The present studies indicate that no abnormal junction of PBS but stenosis of the distal common bile duct may be etiologically responsible for the choledochal cyst.


Traffic in Souls (Universal, 1913) inaugurated a spate of so-called white slave pictures at a time the US was experiencing a moral panic over prostitution. The film enacts a sexual and racial geography of the industrial city, one that is mobile and aleatory and requires a similarly mobile yet self-possessed subject to navigate it and its dangers successfully. Social reformers staffing the National Board of Review of Motion Pictures sought to steer the narrative outcome of the film toward a certain moral end, one that encouraged the production of a governmental subjectivity for its white, female spectators. This was a 'constructive' regulatory agenda toward sexuality through cinema that worked in tension with the more coercive statutory prohibition of prostitution, one that was thoroughly racialized through its exclusion of African Americans from concern.


This research-in-progress paper evaluates the literature regarding "distress" in information systems (IS) development projects. An IS project is seen as distressed when experiencing critical problems that may ultimately result in project failure. This paper first discusses the notion of IS project distress in contrast to IS project failure and briefly examines corresponding literature. A more detailed review of existing research on IS project distress shows that two different interpretative perspectives—process and narrative—have identified several problems that cause distressed states in IS development projects and ways of responding and coping with such problems. While little attention has been devoted to research on IS project distress, the results of this research stream are highly relevant and valuable for real life project situations. Based on our literature review, we propose shifting research focus towards IS project distress and problematic situations experienced during IS development projects.


The adventure of the critic. The aim of this paper is to reply the critical observations made by Fernandes, Rego and Gala in this number of Revista de Economia Politica about a paper of mine, also published in this same journal in January 2006, which deals with the relationship between Economics and Rethoric and its unfolding in Brazil. Answering these critical observations I have tried to show that: a) it is not easy, as they do, to associate Habermas's project to the defense of the approach of Rethoric in Economics; Habermas himself has a lot of objections to the association of his project with Rorty's pragmatism which seems to be the strongest McCloskey's influence; b) it is not true that my considerations have a kind of epistemological immunity and that they are not liable to contestations; if it seems so it is because the nature of the materialistic approach itself. At the end I observe that my carpers didn't reply my observations about the unfolding of the rethorical project in Brazil and that this is, at some measure, surprising, because they are central personages in it.


Cloud computing has gained popularity in recent times. Cloud computing is internet based computing, whereby shared resources, software and information are provided to computers and other devices on demand, like a public utility. Cloud computing is technology that uses the internet and central remote servers to maintain data and applications. This technology allows consumers and businesses to use application without installation and access their personal files at any computer with internet access. The main aim of my work is to study various problems, issues and types of scheduling algorithms for cloud workflows as well as on designing new workflow algorithms for cloud Workflow management system. The proposed algorithms are implemented on real time cloud which is developed using Microsoft .Net Technologies. The algorithms are compared with each other on the basis of parameters like Total execution time, Execution time for algorithm, Estimated execution time. Experimental results generated via simulation shown that Algorithm 2 is much better than Algorithm 1, as it reduced makespan time.


This article introduces an effective rotation and scale invariant log-polar wavelet texture feature for image retrieval. The proposed feature is an attempt to enhance the existing content-based image retrieval systems that largely present difficulty in coping with images with changes in orientations and scales. The underlying feature extraction process involves a log-polar transform followed by an adaptive row shift invariant wavelet packet transform. The log-polar transform converts a given image into a rotation and scale invariant but row-shifted image, which is then further processed through an adaptive row-shift invariant wavelet packet transform operation to generate adaptively selected subbands of rotation and scale invariant wavelet coefficients, based on an information cost function. An energy signature is computed for each subband of these wavelet coefficients. To reduce feature dimensionality, only the most dominant log-polar wavelet energy signatures are selected for the feature vector for image retrieval. The overall feature extraction process is quite efficient and involves only O(n . log n) complexity. Experimental results show that this rotation and scale invariant wavelet feature is quite effective for image retrieval and outperforms the traditional wavelet packet signatures.


A novel divide-by-4 injection-locked frequency divider (ILFD)is proposed and was implemented in the TSMC 0.18 μm 1P6M CMOS process. Conventional harmonic mixer divide-by-4 ILFD has limited locking range, and this letter shows a wide locking range divide-by-4 LC ILFD designed with one linear mixer divide-by-2 ILFD stacked on the top of the other linear mixer divide-by-2 ILFD. At the drain-source bias of 1.6V and at the incident power of 0 dBm, the locking range is 5.7 GHz (42.8%)from 11.4 to 17.1GHz at the power consumption of 9.93mW. The free-running oscillation frequency is 2.6GHz. The die area is 0.644 ×0.908mm2.


The invention relates to a planer type milling machine with a vacuum sucker, a movable working platform and a fixed cross beam. The milling machine realizes three-shaft linkage through numerical control, and since each shaft adopts a high-power alternating current servo motor, the numerical control planer type milling machine can provide strong axial thrust. The numerical control planer type milling machine comprises a numerical control milling machine, a mainframe of the milling machine consists of a machine body, two upright columns and a cross beam which are connected together and combined into a high-rigidity closed planer type frame structure. The fixed cross beam is provided with a vertical ram type vertical milling head with an alternating current variable-frequency speed regulation motor for driving a main shaft; the machine body is provided with a movable working platform and has three feed coordinates; the working platform longitudinally reciprocates along a linear rolling guide rail on the machine body and the reciprocating direction of the working platform is X direction; a slide carriage is installed on the cross beam and transversely reciprocates along a linear guide rail and the reciprocating direction of the slide carriage is Y direction; a vertical ram is installed on the slide carriage and moves up and down vertically and the moving direction of the vertical ram is Z direction; and an electric cabinet is fixed behind the cross beam and an operating panel is of a mobile type.


We extend our previous study of taste-symmetry breaking using HYP-smeared staggered fermions in two ways. First, we improve the statistics of a comparison of unimproved and HYP-smeared staggered fermions on quenched lattices with a � 0.1 fm. This allows us to obtain a signal for all pion tastes, rather than just a subset, and thus to make a c omplete comparison. In addition, it allows us to differentiate between wall and local sources . Second, we compare HYP-smeared valence quarks to asqtad valence quarks on 2+1 flavor unquenc hed MILC lattices. We find that taste breaking is substantially reduced by HYP-smearing, bringing the size of this discretization effect (which is the dominant such effect with staggered fermions) down to the size expected generically for any fermion type.


We have studied the influence of the growth direction and the solidification speed on crystal quality of the silicon‐on‐insulator (SOI) film by laser recrystallization. In a 〈100〉 direction on a {100} Si substrate, lateral epitaxial growth of single‐crystal regions from a seed extended as much as 1 mm. It was found that the crystalline orientation of the SOI film changes continuously from {100} toward {110}. These results indicated that the quality of the SOI film is strongly affected by the crystallographic arrangement of the growth front relative to the composition of {111} faceted planes. A new recrystallization method for large area SOI films was developed by stabilizing the growth front.


Intracranial aneurysm rupture is one of the main cause for the intracranial bleeding. A brain aneurysm is an abnormal focal bulging of the arteries in the brain. As an aneurysm grows, its wall becomes thinner and weaker, which is more prone to rupture. Rupture of the intracranial aneurysm leads to releasing blood into the spaces around the brain called a subarachnoid hemorrhage (SAH). 10 to 15% of the patients with subarachnoid hemorrhage die immediately. To prevent aneurysmal bleeding, it is essential to seclude the aneurysm from the blood circulation. This can be done with open craniotomy with microsurgical clipping and minimally invasive endovascular surgery. One of endovascular surgical technique is to place stent/flow-diverter across the neck of the aneurysm. The stent across the aneurysm reduces the flow within the aneurysm and help to form the thrombus within the aneurysm. However, approximately 3% people with the flowdiverter treatment may have delayed aneurysm bleeding after the stent placement. Short-term studies show that the stents can reduce the flow within the aneurysm but not the pressure. Currently there is no other device available to measure the intracranial intraaneurysmal pressure.


This study presents new findings of the water/ethanol (ratio) influence on the aniline hydrochloride polymerization process in presence of ammonium persulfate. Water/ethanol mixtures in presence of monomer hydrochloride, as proved by the conductometric, spectrophotometric and refractometric investigations, are far from ideal solutions and promote a partitioned environment , for the polymerization process. By controlling this key parameter (water/ethanol ratio) the polymerization can be shifted from a initial dispersion process to a solution one, followed by precipitation. The associated phenomena revealed modification in terms of conversion, structure (FTIR, UV-VIS), morphology (SEM), thermal stability and doping agent retention (TGA-DTG).

Research on excavation of rectangular heading face is conducted to understand the characteristics of air flow in the process of heading face excavation in underground metal mining with a forced ventilation system. The air flow field of forced ventilation in heading face excavation is a confined wall-attached jet flow limited by space, whose characteristics have great influence on ventilation of roadway. Problems such as dust and hazardous gases are tightly related to the characteristics of the jet flow. The jet flow in the excavation process of heading face working is a confined wall-attached jet flow, which is subject to limited space and makes it extremely difficult for the mine to effectively ventilate; the characteristics of jet flow are not fully consistent with those in the unlimited space. In order to improve the ventilation in heading face excavation of Fankou lead-zinc mine, a standard k-e mathematical model of confined wall-attached flow field in the heading face excavation process is established and the boundary conditions of the model are determined.GAMBIT is employed for mesh generation, and the computational fluid dynamics(CFD) software FLUENT is selected to simulate the air flow field. The results are as follows. Firstly, the flow filed can be divided into 3 parts, that is, wall-attached jet area, impact jet area and backflow area; secondly, the initial length of the confined wall-attached jet is less than the value obtained by theoretic analysis; thirdly,the jet wall axial velocity is larger than that of the central inlet of the tube after the confined jet flow is fully attaching. The paper reveals the characteristics of the flow field, and is useful for the improvement of ventilation effect of confined wall-attached jet in heading face excavation.


This paper proposes a design concept in the area of overtopping ocean wave energy devices. Current models of overtopping devices are limited to locations which experience large wave activity. The high energy associated with large waves enables the ocean water waves to overtop the device ramp into the collection reservoir which discharges through a power generating turbine. The ramp height is necessarily large to establish a sufficient collection reservoir head. The proposed design concept can utilize small waves by implementing a gearing system which can transfer water to the collection reservoir. This allows for greater access to the wave energy resource at more locations than currently possible. A simplified model of this design concept is presented and applied to varying wave conditions off the coast of California.Copyright © 2010 by ASME


Navigation in large and complex virtual worlds is a challenging interaction task that needs to meet various requirements. Most existing 3D navigation techniques usually only fit for some special virtual scenes. In order to improve adaptability and performance of navigation technique, a new 3D navigation technique, fast-speeding navigation combining walking with flying, is proposed. This technique automatically controls and switches modes and metaphors of navigation according to user's intentions and the context of virtual environment. Through seamless combination of flying and walking, the efficiency of navigation in complex virtual environments can be improved effectively.

Nanometer-sized particles of W are of interest in semiconductor device research, where such particles may store electrons inside heteroepitaxially defined structures. In this paper, we present results concerning W particles produced by thermal decomposition of tungsten hexacarbonyl. By the described method, it was possible to produce size-selected, single-crystalline W particles in the size range between 15 and 60 nm. The sintering behavior of the particles was studied between ambient temperatures and 1900 °C. The particle morphology and structure were examined with high-resolution transmission electron microscopy and electron diffraction techniques. Particles sintered at the highest temperatures typically were single crystals, with well-developed facets. Some problems concerning a yield reducing charging mechanism are discussed.


Abstract Calcite (Mohs hardness 3), fluorite (hardness 4) and periclase (hardness 5 1/2) have been eroded by snow blown at moderate wind velocities, at temperatures between —10 and —25°C. Future interpretations involving ventifacts and apparently wind-blasted rock exposures must take this information into account.


In this article the author discusses the positive economic outlook of Virgin America after one year of business. The airline has carved its niche in the industry by providing the most recent technology, focusing on providing high-quality and high-value at a low cost. With recent cash-flow from investors, plans are being made to expand both the airplane fleet as well as the number of destination cities. The company stresses that it does not intend to enter a secondary market, contributing much of its success to the fact that it has remained small and invested in ancillary revenue. The article briefly overviews the history of the airline and its struggle to prove that it is controlled primarily by U.S. citizens. Despite a reshuffling of management positions, shareholders and primary creators are pleased with last year's fiscal results.

When applied for molding purposes, mixture is well suited as containers or storing foodstuffs for microwave freezing stoves and caps which retain adequate elasticity at low temperature, thus making it possible to open easily such containers. EFFECT: improved properties of the polyolefin composition. 1 cl, 6 dwg, 11 tbl


The on-line environment that the IOLE project is to provide implicitly includes the specification of some suitable hardware (HW) architecture. The IOLE project in fact is also to focus current trends in HW design, so as to single out adequate existing processor architectures suitable for Integrated Broadband Communications (IBC), bearing in mind that any future IBCN shall be both multi-country and multi-vendor. The future IBC systems must provide a high degree of flexibility, permitting software changes for the purpose of introducing new services or modifying existing ones. At the same time, IBC systems must offer a high degree of availability. In order to cope with both requirements, on-line software extension mechanisms are needed that offer the possibility to add, delete or replace software within a system without disturbing the activities carrying real traffic. The paper presents initial steps towards a methodology for determining an extension strategy, i.e. a plan for the execution of the extension, to guide the on-line replacement of a particular software component.

High-performance electrical drives can be achieved by usingeld-oriented controllers, which make torque and ux naturally decoupled. A conventional vector-controlle d drive has the disadvantage of either requiring ux and speed sensors or being affected by rotor resistance, which varies along with the motor performance. The presented paper focuses on developing a high-performance sensorless rotor ux-oriented controller of an induction machine independent of the rotor resistance variation. This method applies spectral theory of Walsh functions, which are one of the most helpful members of piecewise constant basis functions in solving dynamic models. Inherent characteristics of Walsh functions and application of an operational matrix will make the system handy and robust against inverter switching effects.


In this work, the surface tensions of carbonated diethanolamine (DEA) aqueous solutions from 293.15 to 323.15 K were measured by using an automatic surface tension meter. A thermodynamic model applicable for the surface tensions of carbonated DEA aqueous solution was proposed and the calculated results agreed well with experiments. The influences of temperature, DEA concentration and CO2 loading were demonstrated on the basis of experiments and theoretical calculations.


Expansive soils are materials composed mainly of active minerals of the smectite family, where montmorillonite is an essential member of that group. These types of soils tend to undergo volumetric changes due to variations in moisture content. Many geotechnical engineering practices, such as dam core design or subgrade compaction, require a thorough evaluation of the response of these soils to determine placement conditions. However, the main problem in evaluating the mechanical response of this type of soil lies in the nonlinear nature, which limits the use of most classical constitutive models that apply the basic rules of elastoplasticity. In this study, an analysis is carried out to understand the hydromechanical behavior of expansive soils in saturated and unsaturated conditions. Direct and indirect physical evidence is presented and discussed to evaluate the hydraulic response of the soil structural elements responsible for these adverse dynamics from a global (expansive phenomena as a whole) and individual (swelling and shrinkage) perspective. Since the response of these soils is hydrostatic dependent, the locus of water movement in porous media is examined, starting from the Richards equation (1931), in order to consider the flow mechanisms in unsaturated media under transient conditions.
