An investigation has been conducted at static conditions (wind off) in the static-test facility of the Langley 16-Foot Transonic Tunnel. The effects of geometric thrust-vector angle, sidewall containment, ramp curvature, lower-flap lip angle, and ramp length on the internal performance of nonaxisymmetric single-expansion-ramp nozzles were investigated. Geometric thrust-vector angle was varied from -20 deg. to 60 deg., and nozzle pressure ratio was varied from 1.0 (jet off) to approximately 10.0.


ABSTRACT Christoph Brumann and David Berliner, in their book World Heritage on the Ground: Ethnographic Perspectives (2016), ask what World Heritage (WH) does on the ground far away from the meeting halls of the WH Committee. This article explores the ways in which WH moves and breathes on the ground of Calle Crisologo, Vigan City in northern Philippines. Utilizing participant observation and key informant interviews and building on Edward Soja's notion of Thirdspace, it aims to unpack differences of meanings with regard to the ways WH gets negotiated by locals. The themes of remembrances, counter-memory, impacts and meanings of WH, rootedness and counter practices, and postcoloniality problematize and enrich WH's relationship with local histories, memories, societies, identities, and economies. Shown through the variegated accounts are the ways in which people's engagement with the street turns it into a fecund and volatile, real and imagined lifeworld of experiences. Findings and lessons relate well to heritage's meaning, value, and significance – such as, for instance, the ways that local people's voices can be better valued for more sustainable and inclusive heritage, culture, and memory of Vigan City and elsewhere.


The object of this research is PT KMN which is one of the largest media companies in Indonesia that focuses on reporting or providing the latest information on a national scale. The problem that occurs in this company is the difficulty of grouping complaints to the helpdesk and supporting divisions through the application and the success rate in returning data that does not reach 50% which makes all data that is backed up and carried out regularly becomes useless. The author conducted an audit on the Microsoft System Center 2012 R2 application to find out whether it was in accordance with business process procedures, data accuracy, and problem management. The author analyzes and chooses to use the COBIT 5 Framework in this study. The research methods carried out are interviews and direct observation in the part of the company concerned. The chosen domain is Deliver, Service and Support (DSS) which focuses on the IT process DSS01 had an average value of 2.6 and DSS02 had an average value of 2.43.


Self‐similar solutions are given that represent an analytical theory of implosion and extension stages of a Θ pinch before the magnetic field lines reconnection in course of formation of field‐reversed configuration. Effects of Ohmic dissipation, thermal conductivity, and plasma turbulence are included. The self‐similar solutions, obtained in an explicit analytical form, demonstrate that magnetic flux is trapped during the implosion and expansion stages for a classical plasma, and that losses of magnetic flux are possible for a turbulent plasma during the expansion stage. The rate of flux trapping and diffusion is expressed in terms of experimental parameters.


Measurements of working capacity in the factory should include tests of aerobic power, obesity, and strength. Aerobic power shows a progressive decline throughout the span of working life, and by the age of 60 many men and almost all women seem unlikely to sustain an eight-hour work load at three times the resting level of energy expenditure without fatigue. Workers over the age of 40 carry a substantial burden of body fat, and diminishing muscle strength also increases their liability to fatigue. The relation of these findings to productivity is discussed, and the possible improvement of working capacity through use of an appropriate training regime is set at 15% to 20%. Motivation to increased activity is considered, and is suggested to be a justifiable charge upon company finances.


Knowledge of joint kinematics in the lower limb is important for understanding joint injuries and diseases, and evaluating treatment options and outcomes. However, limited information is available about the kinematics of the lower limb joints in high flexion during floor sitting activities. In this study, we used an electromagnetic motion-tracking system to measure the hip and knee joint kinematics of ten healthy male and ten healthy female subjects sitting into and standing out of the following positions: kneeling on knees, sitting cross-legged, kneeling with legs to the side, sitting with legs outstretched, and deep squatting. We also measured the hip and knee kinematics when donning and removing a sock while standing or sitting on the floor, since they require the same high joint flexion required for floor sitting activities. First, the data were used to produce joint angulation patterns against the normalized time for each individual performing each activity. We proposed a way to split the kinematic curves into 3 to 5 phases in order to preserve the typical features of the original curve, even after statistically aver-aging all the curves. Next, the maximum hip and knee joint angles during each motion were identified directly from the original curves. Furthermore, the relationship between the hip and knee joint excur-sions was investigated. The results indicated that in most activities, the maximum joint angles did not occur during when resting on the floor but during the sitting or standing phase. Among all the activities, donning and removing a sock while standing required the maximum hip flexion angle of 157.5±20.4°, and the motion starting with one foot forward to sit into or to stand out of the kneeling required the maximum flexion angle on the forward knee of 157.1±10.0° respectively. In most of the motions inves-tigated, a strong relationship was found between the hip and knee joint motions, indicating the bi-artic-ular muscles' co-contraction during the sit to stand activities.


The unprecedented reaction of indoline-2,3-diones (I) with difluoromethylene phosphabetaine (II) gives rise to novel 3-fluoroalkenyl-3-trifluoromethyl-2-oxindoles (III), which are converted into derivatives (V) and (VI).


This paper applies two recently developed trading algorithms to a water quality trading (WQT) market located in the Cub River sub-basin of Utah; a market that includes both point and nonpoint sources. The algorithms account for three complications that naturally arise in WQT markets: (1) combinatorial matching of traders, (2) trader heterogeneity, and (3) discreteness in abatement technology. The algorithms enable a full characterization of the market's performance by distinguishing a specific pattern of trade among market participants, which in turn results in as detailed a reduced- cost trading benchmark as possible for the basin. Contrary to the commonly held belief that relatively high point-source abatement costs necessitate nonpoint-source abatement effort, we find that in a WQT market where each source is required to reduce its pollution loadings it may be cheaper for point sources to sell abatement credits to nonpoint sources.

The design builds the enterprise LAN by dividing the IP address and VLAN, and the main configuration of the switch and router. With the establishment of the enterprise network as the center, enterprises can transmit information to each system in a timely and accurate manner, and realize the sharing of resources among various departments. The results show that it can provide theoretical basis and practical guidance for the construction of enterprise network.


Food engineers do not often realise that drying of foods and biological materials is a problem of preserving or transforming structures rather than one of removing water. Some unique product properties depend on the structure of dried foods: rehydration and instant properties, flavour retention and sensorial attributes (including colour and texture). The role of structure extends in biochemical and pharmaceutical products to the molecular level and plays key role in viability of desiccated plants and organisms and/or specific activity of dried biomolecules. Nowadays different techniques and probes are available to visualise changes in structure down to the nanostructural level, acquire physicochemical data of micron-size regions and perform physical/mechanical testing in situ. Most novel visualisation methods are non-intrusive permitting image and data acquisition in real time under simulated or current drying conditions. An emerging field of work is that of quantification of structural features using advanced image processing techniques and fractal analysis. Meaningful structure-properties relationships of dried foods can then be derived from their analysis that might contribute to the design of new and specific structures to improve food functionality. Combination of the microstructural approach and concepts from food materials science should result in major advances in this important unit operation and in tailoring product properties.


Based on the analysis of glass formation region of Y2O3-Al2O3-SiO2 glass system, the glass composition 5Li2O-18Y2O3-29Al2O3-48SiO2 (LYAS) in mol% central in the glass formation region of Y-Al-Si glass system was chosen for present work. The Tm3+ and Yb3+ were introduced as activators in LYAS glass. The glass samples were prepared by the high-temperature solid-state melting and then the derived YAG glass-ceramic was obtained by heat-treating the precursor glass. The X-ray diffraction (XRD) and scanning electron microscopy (SEM) analysis results indicate that the lattice constant of the obtained glass-ceramic is consistent with the pure YAG phase. The primary crystallite size is calculated to be 46nm and the crystal grains grow with excellent orientation (444) in the internal network. The secondary particle size is estimated to be ~8μm and the large grain size is owing to the particles aggregation. The crystal grains distributed uniformly in the glass matrix, and consistent well with the XRD analysis results.


In the paper two cases are presented where existing steel shafts are replaced by shafts made of fibre reinforced plastic, FRP. The first example is an intermediate shaft on a small patrol craft. The engine output is 440 kw at 1530 rpm on the shaft. The second example is also an intermediate shaft between gearbox and a water jet propulsion unit. The maximum engine output is 2560 kw at 1124 rpm on the shaft. In both cases the shafts are filament would with bonded steel fittings. The weight of the FRP shaft is only about 10% of the weight of the equivalent steel shaft. With steel fittings included the total weight was reduced to 25%-45% of the original steel shaft system. Further more the number of bearings could also be reduced which gives more eight reduction. One interesting feature with the shaft made of FRP is the possibility to tailor the stiffness of the shaft by changing the diameter, type of fibres and the fibre direction. Another useful quality is the possibility to accept a higher deflection than for steel shafts. This results in a higher alignment error can be accepted which also means that flexible couplings can be avoided in the shaft system with flexible mounted engines. These last features saves not only weight but also costs. In the last part of the paper other types of equipment made of FRP are briefly described. Examples are lift fans and vent values for SES. Finally a general information regarding the manufacturing method of filament wounded components is presented.


The reasons for the cooperative movement growth at the end of the XIX century not only in the country as a whole, but in Siberia in particular are considered. The difficulties with cooperation growth did not prevent Russian cooperation from becoming the largest in the world at the beginning of the XX century.


A study of helminths infecting juvenile and adult sockeye salmon (Oncorhynchus nerka) leaving and entering the Kvichak River system, Bristol Bay, Alaska, was conducted in 1969. Ten helminths acquired in fresh water were found in smolts: Diplostomulumsp.; an unidentified trematode; Diphyllobothrium spp.; Triaenophorus crassus Forel, 1868: Proteocephalu8 sp.; Euboth"ium salvelini (Schrank, 1790); Neoechinorhynchus rutili (Mueller, 1789); Philonema oncorhynohi Kuitunen-Ekbaum, 1933; Rhabdochona sp.; and Contracaecum sp. In addition to surviving larval stages of freshwater parasites, adults were infected by nine helminths acquired in the sea: Gyrodactyloides strelkowi Bykhovskaya and Polyanskaya, 1953; Lecithaster gibbosus (Rud., 1802); Brachyphallu8 crenatus (Rud., 1802); Tubulovesieula lindbergi (Layman, 1930); Phyllobothrium, caudatum (Zschokke and Heitz, 1914); Echinorhynchus gadi Mueller, 1776; Bolbo807na caenoforme Heitz, 1920; Anisakis sp.; and Contracaecum sp. Infection incidences and intensities are tabulated where accurate data are available. Information on life histories is assembled from scattered sources, and some ecological aspects of helminths infecting Kvichak sockeye salmon are briefly discussed. The Kvichak River system is the largest pro ducer of sockeye salmon, Oncorhynchus nerka (Walbaum), among five river systems in Bristol Bay, western Alaska. Its drainage basin covers nearly 8,000 square miles and includes two large lakes, Iliamna Lake (90 miles long and up to 26 miles wide) and Lake Clark (50 miles long and up to 4 miles wide). Intensive studies on sockeye salmon from this system and the other four systems, the Wood River, Naknek River, Egegik River, and Ugashik River, have been underway since 1946 (Thompson, 1962). Recent research has been directed toward determining the biological basis for annulll fluctuations in

Fatty acids composition in the muscle of of Onychostoma lini(Wu) on the Fanjingshan Mountain were dtermined by hydrolytic extraction-gas chromatograhy. The results showed that there were 21 kinds fatty acids in muscle of O.lini, the total fatty acids was 8.45 g/100 g.The content of unsaturated fatty acids was 70.77%, monounsaturated fatty acids was 37.63%,polyunsaturated fatty acids was 33.14%, total DHA and EPA was 9.59%.


We developed a biochar model within the Agricultural Production Systems sIMulator (APSIM) software that integrates biochar knowledge and enables simulation of biochar effects within cropping systems. The model has algorithms that mechanistically connect biochar to soil organic carbon (SOC), soil water, bulk density (BD), pH, cation exchange capacity, and organic and mineral nitrogen. Soil moisture (SW)–temperature–nitrogen limitations on the rate of biochar decomposition were included as well as biochar‐induced priming effect on SOC mineralization. The model has 10 parameters that capture the diversity of biochar types, 15 parameters that address biochar‐soil interactions and 4 constants. The range of values and their sensitivity is reported. The biochar model was connected to APSIM's maize and wheat crop models to investigate long‐term (30 years) biochar effects on US maize and Australia wheat in various soils. Results from this sensitivity analysis showed that the effect of biochar was the largest in a sandy soil (Australian wheat) and the smallest in clay loam soil (US maize). On average across cropping systems and soils the order of sensitivity and the magnitude of the response of biochar to various soil‐plant processes was (from high to low): SOC (11% to 86%) > N2O emissions (−10% to 43%43%) > plant available water content (0.6% to 12.9%) > BD (−6.5% to −1.7%) > pH (−0.8% to 6.3%) > net N mineralization (−19% to 10%) > CO2 emissions (−2.0% to 4.3%) > water filled pore space (−3.7% to 3.4%) > grain yield (−3.3% to 1.8%) > biomass (−1.6% to 1.4%). Our analysis showed that biochar has a larger impact on environmental outcomes rather than agricultural production. The mechanistic model has the potential to optimize biochar application strategies to enhance environmental and agronomic outcomes but more work is needed to fill knowledge gaps identified in this work.


In this paper we describe a computational approach to the optimal output feedback control of multi-model systems by means of a unique constant output feedback matrix. Extension of the method to output feedback control of multi-model periodic systems is also presented. The power of the proposed approach is illustrated by the simultaneous stabilization and optimization of a helicopter multi-model.


We have begun this volume of Health Care for Women International with a series of articles about research on women and cancer. Topics range from an analysis of macro-structural issues that affect international treatment priorities to micro-social studies of how women cope when their illnesses are acute or in remission. Some of the studies include data on participants who are young women while others examine long-term survivors. We are pleased to publish a study on the effects of risk counseling for sexual minority women. All of the research is excellent, thus I have kept my editorial comments to a minimum. As always, I want to remind readers that we will publish letters submitted to the editor about any article in this volume in order to stimulate further discussion.


The chemical composition of 217 Galactic planetary nebulae is investigated; 203 of them are subdivided into four classes according to the masses of nebulae and progenitor stars. The values of local abundances, Galactic abundance gradients and Galactic electron temperature gradients are found for each class of nebula. The correlations between the abundances of pairs of elements are also calculated for each class of nebula. The results are compared with theoretical predictions. In particular, it is concluded that CN cycling can play a role in progenitor stars for all classes of planetary nebula


The aim of this study was to analyse milk yield, milk composition and other performance indicators in Czech Pied cows raised in the Czech Republic as compared with Polish Holstein-Friesian, Simmental and Czech Pied cows raised in Poland. The experimental materials comprised cows enrolled in the milk recording scheme in 2011, of the following breeds: Polish Holstein-Friesian (PHF) (438 376 cows), Simmental (SIM) (9 559 cows), Czech Pied tested in Poland (CP-P) (34 cows), Czech Pied tested in the Czech Republic (CP-Cz) (110 436 cows). The following parameters were determined: yield [kg] of milk, fat and protein, content [%] of fat and protein in 305-day lactations: the first lactation (L-I), the second and subsequent lactations (L-IIS), the length of: inter-pregnancy interval (IPI), intercalving interval (ICI), gestation period and dry period, as well as artificial insemination efficiency and conception rates on selected days of IPI. PHF cows produced the highest yields of milk and milk components in the analysed lactations, in comparison with the other cattle breeds. Milk fat content was relatively high in all cattle breeds, exceeding 4% in both L-I and L-IIS. Milk protein content was highest in CP-Cz and CP-P cows, at 3.53 – 3.54% in L-I and 3.46% in LIIS. PHF cows calved at the youngest age, had the longest IPI, ICI and lactation periods, and the shortest gestation period, compared with the other cattle breeds. Over a three-year period, SIM cows produced 25% less milk than PHF cows. The average lifetime productivity of the highest-yielding CP-Cz cows was 108342 kg milk (3.39% protein content and 3.79% fat content) and 7038 kg fat and protein. The highest number of CP-Cz cows conceived at 120 days or more (41.6%) and within 90 days (39.9%) of calving, which testifies to the success at first insemination. High genotypic diversity was noted in CP-Cz cattle, which contributed to a considerable increase in milk yield in cows containing 87% or more CP-Cz genes.


In this paper I extend the area interpretation of linear and angular momenta of ideal vortex filaments to complex tangles of filaments in space. A method based on the extraction of area information from diagram projections is presented to evaluate the impulse of vortex knots and links. The method relies on the estimate of the signed areas of sub-regions of the graph resulting from the projection of the vortex axes on the plane of the graph. Some examples based on vortex rings interaction, vortex knots and links are considered for illustration. This method provides a complementary tool to estimate dynamical properties of complex fluid flows and it can be easily implemented in real-time diagnostics to investigate fluid dynamical properties of complex vortex flows. c © 2012 Published by Elsevier Ltd.

This paper describes the design of a multi-modulus prescaler for /spl Sigma/-/spl Delta/ fractional-N frequency-synthesizers. A new architecture is proposed to increase the critical time window for correct division. Quantification of the improvement of the architecture is done on the behavioral and transistor levels. The architecture is used to implement a multi-modulus prescaler with division factors 64-127 in a SiGe 0.35 /spl mu/m BiCMOS technology with f/sub t/ of 60 GHz. The architecture improves the maximum operating frequency of the prescaler by 50%. Post layout simulations indicate that the prescaler can operate at an input frequency of 3.2 GHz while consuming only 6.4 mW, with a phase noise floor of -132 dBc/Hz, and up to 4.6 GHz while consuming 14 mW.


ABSTRACT This paper investigates the prominent failure modes of educational facilities by using field observations. Specifically, damage to the roof covering, roof structure and exterior windows were quantified. An archetype of these structures is modeled in a Monte Carlo Simulation wherein the probabilistic resistance capacities of the building envelope components are compared to their corresponding probabilistic wind loads. The probability of exceedance is then evaluated at three levels of damage state per 3-s gust wind speeds. For the vulnerability curve, the results were fitted into a cumulative probability density function with a mean of 4.7314 and a standard deviation of 0.4061. The results of the model are then evaluated through a case study of Typhoon Nina 2016. The model generally underpredicts the mean damage ratio per municipality by about 13.17% for wind speeds of 40.225 m/s and by about 3–6% for wind speeds between 49 m/s to 71 m/s. The reported damage by the respective government authorities was aggregated on a municipality level and compared to the performance of the model. A statistical analysis between the reported and mean predicted damage was also done by using the Spearman rank correlation coefficient. The results yielded a positive correlation of 0.856. Graphical Abstract


Low robustness under mobility is the Achilles' heel of the emerging 60 GHz networking technology. Instead of using omni-directional antennas as in existing Wi-Fi/cellular networks, 60 GHz radios communicate via highly-directional links formed by phased-array beam-forming, so as to upgrade wireless link throughput to multi-Gbps. However, user motion causes misalignment between the Tx's and Rx's beam directions, and often leads to link outage. Legacy 60 GHz protocols realign the beams by scanning alternative Tx/Rx beams. But unfortunately this tedious process can easily overwhelm the useful channel time, leaving the Tx/Rx in misalignment most of the time during mobility. In this paper, we propose Beam-forecast, a novel model-driven beam steering approach that can sustain high performance for mobile 60 GHz links. Beam-forecast is built on the observation that 60 GHz channel profiles at nearby locations are highly-correlated. By exploiting this correlation, Beam-forecast can reconstruct the channel profile as the Tx/Rx moves, without explicit channel scanning. In this way, it can predict new optimal beams and realign links for mobile users with minimal overhead. We evaluate Beam-forecast using a reconfigurable 60 GHz testbed along with a trace-driven simulator. Our experiments demonstrate multi-fold throughput gain compared with state-of-the-art under various practical scenarios.


On July 15–17, 2009, 544 biology faculty from 2- and 4-year colleges and universities, along with researchers, administrators, students, and other educational stakeholders from around the country, met in Washington, DC, to help create a blueprint for the future of undergraduate biology education (Summers, 2009 ). Hosted by the American Association for the Advancement of Science (AAAS), with support from the National Science Foundation (NSF), the meeting set out to mobilize the nation's undergraduate biology educators to ensure that the biology they teach in their classrooms reflects the biology they practice in the lab and field, and that all students—majors and nonmajors alike—gain a better understanding of the nature of science and the natural world (Mervis, 2009 ). The charge for the meeting (Transforming Undergraduate Education in Biology: Mobilizing the Community for Change) noted that the need for change reflects the radical changes in the science itself as well as the knowledge we are gaining about how people learn and the best ways to ensure that learning takes place. The meeting concentrated on how people have effected change, the results when they did so, and how the attendees and their colleagues could most effectively incorporate this knowledge and understanding into their own approaches to undergraduate education in biology. Videos, slides, and other materials from the meeting are posted at the conference website (AAAS, 2009a ). A culminating summary publication is anticipated in spring 2010.


Abstract The corrosion resistance of zinc electrodeposited on to an electropolished steel substrate at different current densities was investigated. Electrodeposition at 10 mA cm−2 resulted in fully epitaxial growth of zinc while completely non-epitaxial growth of zinc is obtained at 200 mA cm−2; at currents of 100 mA cm−2 both epitaxial and non-epitaxial components exist. The coatings deposited at 10 and 200 mA cm−2, which have only one texture component, reveal higher corrosion resistance. High percentage of (00·2) basal planes parallel to the substrate provides higher corrosion resistance for the coating at 200 mA cm−2. However, full epitaxial growth at 10 mA cm−2 provides fewer grain boundaries, which could be the reason for its higher corrosion resistance. The coating formed at 100 mA cm−2 allows easier hydrogen discharge and therefore shows lower corrosion resistance with respect to the others.


Laboratory researches have been done to find a new and simple method for manufacturing silicified humate products.Taking humic acid and silicifying agent as the raw materials,a new product,silicified sodium humate,GFN-1,with performance similar to organosilicon potassium humate,was synthesized.Field study showed that GFN-1 performed very well in filtration and viscosity control and at high temperatures.GFN-1 also had the ability to inhibit the dispersion of shales.As a mud additive equivalent or even better than organosilicon potassium humate,GFN-1 meets requirements of field application.The abundance of the raw materials,the simple manufacturing techniques,and the stable properties of the product,make it a cost-effective mud additive.

The primary purpose of this study was to review the efficacy of unilateral treatment of lateralized tonsil primaries, in particular whether laterality of the primary is a more powerful determinant of contralateral neck failure than advanced ipsilateral nodal classification.


A boy with severe growth and psychomotor retardation, facial dysmorphism, a large atrial septal defect, limitation of joint movement and hearing impairment is described. High‐resolution banding chromosome analysis showed interstitial deletion of the proximal segment of chromosome 3: 46, XY, del(3)(p12p14.2) de novo. The deleted chromosome 3 was of paternal origin as judged from Q‐banding polymorphisms. Delineation of proximal 3p deletion syndrome is proposed by summarizing the clinical and cytogenetical findings of the present and previously reported five patients.


1. Sticky chromosome bridges and chromosome breaks in the ana- and telophase have been found in the root tips and the ovular tissue of Clivia miniata growing in the greenhouse and outdoor.2. The occurrence of these irregularities was frequent in the root meristem fixed in summer, but infrequent in the material fixed in winter.It is most probable that there is a seasonal variation of frequency in the occurrence of aberrant cells.3. The patterns of abnormalities in the ovular tissue are different from those in the root meristem.4. It is suggested from the present data obtained that both the external conditions enclosing the plant, especially temperature, and cellular metabolic conditions caused by the heritable internal factor are responsible for the aberrations.5. Various degrees of pollen sterility have been observed. Mitotic divisions in the shoot meristem were quite normal.


Following 4 traumatic in-hospital thoracotomies preformed over the summer in a district general hospital we recognised the need for in-situ in-house training. Unfortunately no realistic training tools were currently available for this uncommon emergency procedure. We therefore have constructed our own sim trainer that recreates the anatomy and function of the thoracic cavity and responds to the appropriate interventions. This is fully reusable at very little expense approximately £3 per session and costs under £80 to make. We would perform a demonstration in workshop of how to use this cheap but realistic and reusable emergency thoracotomy trainer. Aimed at trainees of all levels and senior A+E staff, surgical and trauma teams and pre hospital trauma teams. We aim for an informative discussion and demonstration on how to recreate the simulator as well as demonstrating its use in scenario based simulation, teaching the basics of emergency thoracotomy from incision of skin followed by dissection into thoracic cavity, opening fluid filled pericardium, repairing and controlling haemorrhage from pumping heart, proximal aortic control, open cardiac massage and pulmonary hilar compression. We would plan to include a short presentation on creation of the model followed by demonstrating the use in a short trauma scenario. The intended learning outcomes are how to recreate the sim trainer as well as the basics of emergency thoracotomy.


This article draws on my other writings about developments in the teaching of music in Kenya, and on the decision to promote traditional musics and to make music one of the compulsory examinable subjects at the end of primary school. It considers two textbooks published by Oxford University Press in Nairobi: Music Makers for Standards 7 and 8, by Brian Hocking and me, was issued in 1985, and Music Makers for Standards 5 and 6, this time with George Mutura as co-author, was published in 1989. The music education syllabus was revised in 1993, and both books were adapted to adjust the placing and progression of the material. This case study sets out the background of developments in Kenyan educational policy, notes the changes in curricular music, explores how the adaptation happened in practice, tracks the process, comments on its implications and considers responses to the completed project.


Implicit surfaces used in geometric modeling are often limited to two-dimensional manifolds because they are defined as zero-set functions that separate the space into binary regions. Non-manifold implicit surfaces containing singularities such as isolated points or self-intersection points are essentially non-polygonizable. Thus, triangulating and rendering such surfaces are not a trival task. This dissertation presents the design and implementation of an algorithm for triangulating and rendering of non-manifold implicit surfaces using geometric healing techniques. The presented algorithm, called Healed Marching-Cubes (HMC), is built on the standard Marching-Cubes algorithm introduced by Lorensen and Cline in 1987 [LC87]. In the context of implicit surface triangulation and rendering, there are not many proposed algorithms to solve its typical problems such as self-intersection emerged by non-manifold surfaces. Hence, Healed Marching-Cubes will be a valuable contribution to the field of computer graphics and geometric computing.

Abstract This research is a research with a combination method that aims to optimize the implementation of soft skills based on Information and Communication Technology (ICT) in vocational education. The results of this study need to optimize the improvement of soft skills implementation in the era of revolution 4.0 in the realm of vocational education. Acquisition The results of quantitative calculations obtain the result that Intrapersonal Ability is as large as 54,13 % sufficient category and Interpersonal Ability obtained Respondent Achievement Rate of 65.65% is in the Good category.  The results of optimizing the implementation of ICT-based soft skills in vocational teachers in the 4.0 revolution era with a percentage of 59.89 are in the sufficient category.  The ability of a teacher interpersonally includes the teacher having good responsibility in the process of carrying out tasks at school, the teacher has good integrity, and the teacher has confidence in himself and others. Meanwhile, the interpersonal skills possessed by the teacher include the ability to adapt to others or colleagues and others at school, have the ability to negotiate with others, be able to work with teams and have a leadership spirit. In addition, efforts that can be made to optimize ICT-based teacher competencies can be done by increasing the Role of Teachers using digitalization in the Revolutionary Era 4.0 by providing challenges to teachers in developing professionalism and pedagogical competence of teachers in schools and increasing Teacher Competence in Mastering Learning Strategies by trying to connect science and technology into everyday life.


A B S T R A C T Urine was observed to flow intermittently in the collecting ducts of the extrarenal papilla of antidiuretic rats. The purpose of this investigation was to test Reinking and Schmidt-Nielsen's hypothesis that intermittent flow plays an important role in the production of maximally concentrated urine. Samples of collecting duct fluid were obtained from the base and tip of the papilla by micropuncture through the intact ureter. Fluid osmolality rose sharply from base, 894±120 mosmol/kg H20-' (mean±SE), to tip, 1,667±114 (P<0.001), a distance of only 2 mm, and was due exclusively to reabsorption of water. After excision of the ureter, which abolished intermittent flow, osmolality fell modestly at the base to 723±82 mosmol/kg H20-' (P < 0.02), but strikingly at the tip to 1,012±103 (P < 0.001). The pelvic ureter was paralyzed by topical verapamil and dimethylsulfoxide, which abolished intermittent flow. Osmolality of urine at the tip was not changed (1,959±184 mosmol/kg H20-1 before, vs. 1,957±126 after paralysis). The ureter was severed just beyond the papillary tip, a maneuver which preserved intermittent flow but abolished urinary reflux over the papilla. Urinary osmolality fell from 1,876±134 mosmol/kg H20-1 to 1,284±115 (P < 0.005). These findings demonstrate that when the ureter is intact, over half of the increase in urinary osmolality above isotonicity occurs in the terminal onefourth of the medullary collecting duct and is due exclusively to water reabsorption (no net solute addition). It is the continuity of the ureter, rather than intermittent flow due to ureteral peristalsis, which is essential for the formation of a maximally concentrated urine.


The terms "lories" and "lorikeets" are used interchangeably by most authors since the term "lorikeet" merely means "little lory". For purposes of simplicity, only the term "lory" will be used in this paper. The family Loriidae are among the most beautiful, interesting, active and affectionate of all psittacines. This family is extremely large and represents about 116 of total world psittacine population. The family contains about 75 species. Anatomically, the lories differ from other psittacines, by possessing a brush tipped tongue with which they "lap" nectar and liquids like cats. They are excellent breeders; frequently having one clutch after another, yearly. They will often breed freely in rather limited enclosures and, if hand raised, often make excellent "talkers". These are some of the positive points which make lories excellent avicultural candidates. Most of the negative points are mainly focused around the fact that these birds are fruit and nectar eaters. Because of their diet, they have a very liquid excrement which is expelled in a very messy projectile manner. This one characteristic, above all others, makes them very poor candidates for "house pets". Making a well balanced nectar mix for lories is time consuming and rather expensive project. The proper hygenic care of their cages and nectar containers also requires a good deal of time and effort. However, with good outside aviary facilities, the positive points in favor of working with these exciting birds far outweigh the negative points. Besides their unbelievable brilliant colors, the intelligence, inquisiveness and mischieviousness of the lories are among their most attractive qualities. Their activities very closely resembly baby kittens at play. One can constantly observe them making up games to play, either individually or in groups. At times they may be seen lying flat on their back juggling a twig or rock with their feet. Frequently two of them incessantly wrestle or do cartwheels around a branch. Their natural courtship activity of bobbing and wing flapping is an exciting display to behold and is somewhat different for each species. I have even seen five of them line up and march in a straight line, like little toy soldiers, playing "follow the leader". The Dusky Lories will frequently strut around in a circle, like two sparring boxers, with outstretched wings; looking very much like turkey gobblers in mating display. This is mentioned only to point out that lories are constantly involved in innumerable humorous or interesting antics which make them probably the most interesting and desirable of all aviary psittacines to own. It is stated by Tivert and by Forshaw that, in the wild state, the food of lories consists of flower nectar, pollen, blossoms and leaf buds. However, from my personal observations and necessary conclusions from parasites which these birds host, they of necessity must also consume a fairly large amount of insects or other parasitic intermediate host such as insect larvae, worms or even snails. This assumption is made on the fact that a great number of wild caught lories, coming into this country through quarantine, have intestines grossly infested with tape worms. The tape worm obligatorily requires an intermediate host such as insect, worm or snail to complete its life cycle. Some authorities have speculated that this infestation is brought about by the lories accidently consuming an occasional insect while feeding on flowers. I believe that this is an erroneous conclusion and that these birds actively go in search for insects while they have young in the nest, in spite of abundance of other food sources. I have seen parent lories digging through the dirt on the aviary floors for hours in apparent search for insects which they voraciously consume as they find them; as well as eating the roaches and flies that occasionally enter their cages. In sexing the Loriidae, monomorphism between the sexes is the rule and dimorphism is the exception. The dimorphic exceptions which come to mind are the red phase of the Stella's and Josephine's Lori es in which one sex (reportedly, the female) has a yellow rump and the other sex has a red rump. However, in the melanistic (black) phase of the Stella's, both sexes have red rumps. Another genetic oddity in the melanistic phase of the Stella's is that, although the normal red pigment of the face and breast feathers are replaced with black feathers, the rump feathers of these melanistic birds retain their red pigment. In the orange phase of the Dusky Lory, there is also a dimorphic difference in the sexes. The female has a silver-while rump and the male has a yellowish-rump. However, this difference is more difficult to discern in the yellow phase of the Dusky for the rumps of the few I have seen are silver-white in the center and yellow-white in the periphery. In the Edward's Lory, which is the yellow breasted variant of the Rainbow Lories, up until now, the dimorphic difference has been stated that the male may have a few orange feathers scattered among his yellow breast feathers whereas the female's breast feathers are all yellow. In my working with these birds, I have observed a much more striking difference between the sexes. I have found that the adult males have bright orange feathers on the lesser under wing-coverts, while the adult females have clear bright yellow lesser under wing-coverts. So far, the six young that I have raised this year have all had varying degrees of orange under their wings and I suspect that this color difference is only fully developed in adult plumage. Many of the lories having an orange or horn colored beak in adulthood will have black beaks while immature. Therefore, any birds of these species having black coloration on their beaks are probably less than one year of age. The "old wives' tale", still in popular belief among a great many bird breeders, is that, if two eggs are laid, the resulting nestmates will invariably be one male and one famale. This statement is definitely NOT true! This has been proven by recent laparoscopic studies. There will, however, nearly always be a difference in the size of the two nestmates. This difference, l believe, may well be attributable to hatching dates and the first bird getting more food. This difference in size will frequently equilibrate toward the end of the first year, if good diet has been provided for both birds. It has been said that lories only lay two eggs per clutch. I know of one pair of mollucan red lories that laid four eggs in one clutch and all four eggs hatched. A well balanced diet is probably the most important part of successful breeding of all birds; and this is certainly true of the lories. There are probably as many "nectar" mixes for lories as there are people who raise these birds. The lories require a very large glucose (sugar) supply to give them energy for their incessant activity. A high protein component of well balanced amino acids for cellular growth is essential. The amino acid, cystine, and its metabolic precurser, methionine, are very important for good healthy feather production.


Due to the tremendous growth in user population over online social networks (OSNs), interactive messaging traffic has experienced exponential growth, which consequently causes serious privacy concerns. Malicious users may utilize camouflage, phishing, and other unconventional social engineering techniques to lure ordinary users to reveal their sensitive attributes in their interactive messages when they least expect. In addition, during a communication session, attackers may intercept data packets with sensitive attributes to obtain private information. Therefore, it is of paramount importance for the system to successfully identify malicious users and prevent them from obtaining private information from messages containing sensitive attributes when socializing over OSNs. In this article, we propose a privacy-preserving scheme for interactive messaging by leveraging user credibility that characterizes users' reputation based on users' social behaviors and uses the item response theory in psychometrics to assess the risk levels of users' interactive messages. This scheme ensures the privacy preservation during message exchange through message obfuscation with the message replication and the replacement of sensitive attributes. Through the experiments on a Facebook-like Social Network Data Set, we have demonstrated that our proposed scheme has high availability and accuracy while achieving the high success rate to identify malicious users, which can thus greatly reduce the privacy leakage.

Executive Summary: In 2019, the Arctic experienced its second warmest year on record, continuing a six-year trend of record-breaking Arctic surface temperatures (Lindsey 2019). Such unprecedented observations have become the new normal in the Arctic and provide new insights into the implications of global climate change. A warming Arctic, however, also presents new opportunities for Arctic commercial development. Such development is in fact quickly evolving from a mere possibility to an on-the-ground reality. Despite the speed of and increasing prospect of Arctic commercialization, however, there has been little to no movement on the part of the United States to enact policies and regulations accounting for it.


The CN B-X (0-0) R branch fluorescence spectra for three comets (Austin, Bennett, Halley) were calculated and compared to the observed spectra. The synthesized spectrum in each case was shifted to allow for the comparison of the individual line intensities. The Swings effect (excitation of CN band in comet spectra by solar fluorescence) is clearly visible. In addition to the R(0-0) band in the CN spectrum, the P(1-1) band also contributes lines in the spectral region of observation. This branch was calculated and compared to P/Halley. The overall agreement between observations and the CN spectral model is quite good. An exception to this statement would be the high J rotation lines intensities within the R(0-0) branch of P/Halley. Additional analysis is necessary to determine if this difference is due to mechanisms in addition to fluorescence (e.g., collisions).


Determining the tuning constants of a classical PID (proportional-integral-derivative) controller for a slow nonlinear process, such as the temperature loops on a heat-treat of annealing furnace, can be a laborious task. Several tuning methods were considered to identify a method that could be applied easily in the field with limited resources. The method of Ziegler and Nichols (1942) proved to easy and effective. Results obtained by using the Ziegler-Nichols open-loop method to determine the tuning constants for a classical PID temperature controller for a heat-treat furnace are described. The process being controlled is described, and open-loop test data are presented.<<ETX>>


Implementation and disclosure of corporate social responsibility, or better known as corporate responsibility (CSR) started to emerge from three decades ago. Issue of CSR was due to a shift in paradigm where the company now not only aims to maximize profits but also are required to accommodate the needs of the community (society), its enviroments and stakeholders. In this study discusses the concept of three main dimensions of corporate social responsibility, namely benefit, people, and planet on the image of the company that fosters customer loyalty so dont move on product another (switching cost). Population in this recearh is buyer of KFC Semarang and know of CSR. The number of samples that used 96 responden, and technic sampling in this study were taken by using purposive sampling. The data obtained were analyzed by using PLS analysis technique (Partial Least Square). The result showed that the implementation CSR(benefit, people and planet) directly and positively related to company image and customer loyalty, company image has positive effect on customer loyalty and switching cost, furtheirmore switching cost to customer loyalty. Keywords : Corporate Social Responsibility, Image, Loyalty, Switching Cost.


Keyloggers have been widely used by hackers as a tool to steal information and passwords from users in e-commerce. The malware security software has also grown but keylogger grow too. This article reviews some of the techniques used by hackers to spread Keyloggers and bypass various security techniques by using advanced Keyloggers and finally, we describe a novel approach to deal with Keyloggers. This approach, capable of dealing with the most advanced Keyloggers, and greatly reduces damage caused by Keyloggers.


The bonding features and electronic structures of a series of transition metal carbon dioxide complexes have been studied by density functional theory (DFT) calculations combined with natural bond orbital (NBO) analysis and energy-decomposition analysis (EDA). NBO analysis shows that the interaction between the metal center and the carbon atom of the carbon dioxide ligand (M–C) is stronger than the other interaction between the metal center and the carbon dioxide ligand. Natural hybrid orbital (NHO) analysis gives the detailed bonding features of the M–C bond for each complex. The NBO charge distribution on the carbon dioxide unit in all studied complexes is negative, which indicates charge transfer from the metal center to the carbon dioxide ligand for all studied complexes. The hyperconjugation effect of the metal center and the two C–O bonds of the carbon dioxide ligand has been estimated using the NBO second-order perturbation stabilization energy. It was found that the NBO second-order stabilization energy of C–O → nM* is sensitive to the coordinated sphere and the metal center. Frontier molecular orbital (FMO) analysis shows that complexes 1 and 4 may be good nucleophilic reagents for activation of the carbon dioxide molecule. However, the EDAs show that the M–CO2 bond interaction energy of complex 4 is about two times as large as that of complex 1. The high M–CO2 bond interaction energy of complex 4 may limit its practical application.


A SPICE model of a two-phase, permanent magnet, step-motor is presented by the authors. It is capable of predicting, with reasonable accuracy, the electrical and electromechanical dynamics associated with a step-motor system. Central to the modeling process is the use of reference-frame theory to eliminate the time-varying inductances associated with the stator voltage equations, and the SPICE realization of a voltage-control oscillator as a means of synthesizing the sine cosine functions. The resulting step-motor model is shown to be able to predict both single-step and fixed-stepping-rate failure modes of a typical step-motor system.<<ETX>>


There is every indication that an object-oriented view of an information system is a solid foundation for understanding its legacy organization, for relating it to the environment in which it is embedded and for guiding its reengineering. In this paper we present a framework based upon the formal object-oriented specification language TROLL, which provides an object-oriented view of legacy information systems. The aim is to combine existing methods and keep results in a common and suitable description base which provides the appropriate form for deriving object specifications from the legacy IS. We usethe language TROLL not only as description language, but also as a framework to support the maintenance engineers in their reverse engineering tasks by giving hints about what to do next to complete the object specifications. The result of the approach is a formal object-oriented specification of the legacy IS that is suitable both for developing a new IS or for reengineering the legacy system.


Synopsis : The changes in microstructure of Zn—Al alloy coating according to the alloy composition and the cooling rate after coating were investigated, and the influence of microstructure on corrosion properties was discussed. 1) When the specimens were slowly cooled at 5•Ž/s after coating, zinc—rich primary phase precipitated in the coatings which contained less than 5%Al. On the other hand, the coating became eutectic structure without primary phase when it contained 5.2,•`,5.4%Al. 2) Zn-4.5%Al alloy coatings were cooled at various rates after remelting. When the specimen was cooled at 5•Ž/s,•`100•Ž/s, the primary phase precipitated in the coating. The microstructure of the coating became uniform when the specimen was quenched. 3) The primary phase in the coating deteriorated the corrosion resistance in the salt spray test. The uniform microstructure without primary phase showed the best corrosion resistance. 4) It is effective to adjust Al content precisely at eutectic composition or to cool coated sheets as rapidly as posible for getting the uniform microstructure and the good corrosion resistance.


SYNOPSIS While currently available methods of dynamic soil-foundation interaction idealize the soil as a continuum, this paper presents a general theory to obtain the dynamic response of offshore caissons resting on a saturated or nearly saturated poroelastic medium. The model, based on Biot's theory, considers the compressibility of both solid and fluid phase and assumes that the fluid flow is governed by Darcy's Law for an isotropic medium. Results are presented as plots of normalized amplitudes of displacement load or rotation-moment ratios for a rigid strip founded on a dense coarse sand. The results demonstrate that fluid compressibility, which is primarily a function of the dearee of satur ation, has an important effect on rocking motions. Soil premeability appears to have a rather minor effect on the re sponse.


One challenging task in MCMC methods is the choice of the proposal density. It should ideally provide an accurate approximation of the target density with a low computational cost. In this paper, we are interested in Langevin diffusion where the proposal accounts for a directional component. We propose a novel method for tuning the related drift term. This term is preconditioned by an adaptive matrix based on a Majorize-Minimize strategy. This new procedure is shown to exhibit a good performance in a multispectral image restoration example.


TOLEDO, G.I.F.M.,Traffic-related exposure assessment at Sao Paulo city. 2010. Thesis (PhD in Public Health) – School of Public Health, University of Sao Paulo, Sao Paulo. IntroductionSao Paulo is one of the largest cities in Latin America, with almost 11 million inhabitants and around 6 million vehicles. Although traffic is the main source of air pollution, few studies investigated the relationship between vehicle pollution and health outcomes. Most studies analyzed health effects using average concentrations of environmental pollution for the whole city, which cannot give evidence for intra-urban gradients of exposure. ObjectivesTo evaluate the population's exposure to traffic-related air pollution and its association with hospital admission for respiratory diseases among children and adolescents aged 0-18 years. Methods Concentrations of CO, NOx and PM10 were modeled using CALINE-4 dispersion model, in two periods: summer (January) and winter (June). Hospitalizations due to respiratory diseases (by private and public assistance) were geocoded by the residence address. IBGE's census sectors were considered as unit of analysis. A logistic regression model was used to estimate the association between exposure to traffic-related air pollution and hospitalization for respiratory disease which, allowing for HDI as a socioeconomical indicator. ResultsSpatially, pollutants presented higher concentration at the central area of the Expanded Center of Sao Paulo city. Temporally, higher concentrations were observed at winter periods. Trafficrelated pollutants was directly associated with hospitalization for respiratory disease among children and adolescents aged 0-18 years. Children and adolescents who lived in census sectors ranked in the 4o quartile of CO in the winter period had 80% greater chance of being hospitalized for respiratory diseases. ConclusionsTraffic-related pollutants increase the chance of children being hospitalized for respiratory diseases. Socioeconomic conditions (evaluated by the HDI) also raised the chance of hospitalization. The method used in this study is important for micro-scale evaluations of the relationship between vehicular pollutants and population health. Other Brazilian cities or cities from developing countries may benefit from this approach, since models are less expensive and faster than air quality monitoring campaigns or acquisition/maintenance of air quality monitoring stations. Descriptors: traffic-related pollution; exposure assessment; respiratory diseases; Sao Paulo.


Research in unsaturated soil mechanics has considerably developed in the past decades, through the simultaneous development of experimental investigations and theoretical analyses. A fundamental property of unsaturated soil is the ability to store and release water. In this study, an attempt was made to compare the results of bearing capacity of model pile groups constructed in saturated soil prepared at two dry densities and unsaturated soil, with results from theoretical approach (conventional and modified) α, β and λ methods. Square aluminum model piles of 20 x 20 mm in cross section and 200 mm in length were used. The piles were arranged in six group configurations, single, 2×1, 3×1, 2×2, 3×2, and 3×3, groups in addition to pull out test at which the pile is designed to verify this purpose. All groups have the same spacing, which is equal to 3 pile diameters (60 mm). The results showed that using the β method gives the value of ultimate capacity close to the experimental results for saturated and unsaturated tests, while the theoretical results showed overestimation when using other two methods. The results of load displacement curves for piles embedded in soil having three different properties indicate an increase in the ultimate pile load carrying capacity with increase in the number of piles for different soil properties. This increase however, is not linear and gives a high value when the soil becomes in unsaturated state compared to the soil in saturated state.


Abstract The nickel(II) and copper(II) complexes of tetraaza[14]tetraene were prepared and investigated by means of electronic, vibrational, ESCA and ESR spectroscopy. Judging from the ligand-field spectra, these complexes assume the square-planar configurations. The spin Hamiltonian parameters of the copper(II) complex are also consistent with those for the square-planar coordination. The ESCA spectrum of the metal-free tetraaza[14]tetraene showed double nitrogen ls peaks, whereas that of the complexes exhibited a single nitrogen ls peak.


Micro-PMSMs are manufactured by using micro-electro mechanical system (MEMS) technology. In this paper, a micro-PMSM speed control system which has 6 mm diameter and a 100 pulses/revolution micro-encoder is investigated. The adjustable speed of the micro-motor control system is from 100 r/min to 20,000 r/min. To improve low speed performance, a state estimator is investigated. By using a state estimator, the adjustable speed of the micro-motor control system is from 1 r/min to 20,000 r/min. A digital signal processor, type TMS 320F 28335, is used as a control center to execute the state estimator and control algorithms. Experimental results validate the theoretical analysis and show the correctness and feasibility of this proposed method.


In the Guidelines for Drinking-water Quality, the World Health Organisation (WHO) concludes that end-product testing is not sufficient to guarantee safe drinking water to consumers. Such analyses are often completed after the water is consumed and they may not provide correct information regarding the health effects of the water. Instead, WHO recommends preparation of risk-based Water Safety Plans (WSP) from 'source to tap', which considers conditions in source waters, treatment systems and distribution networks. WSP is currently being implemented in several countries and is expected to become increasingly important for water management in both developed and developing countries. WSPs facilitate an increase in awareness and understanding of risk issues fundamental for providing safe drinking water. WHO provides general but not detailed information on risk assessment and risk management procedures in WSPs. The primary purpose of this paper is to describe a framework for a structured risk management in WSPs. The framework is currently being developed within the European Commission Sixth Framework Programme project TECHNEAU (Technology Enabled Universal Access to Safe Water). The suggested framework cannot provide one single risk management method applicable to all types of water utilities. Instead, the framework will provide: (1) principles for good risk management practice; (2) a relevant set of tools; and (3) clear examples. This paper includes: (1) a short review and presentation of WSP; (2) a presentation of the current version of the TECHNEAU Generic Framework for Integrated Risk Management in WSP; and (3) a short description of some risk analysis methods currently being developed in the project.


An analytical investigation of the closed orbit distortions due to ground waves has been made for a model periodic FODO lattice. The response of the closed or bit to a single plane wave and the rms response to an ensemble of uncorrelated waves is expressed as a function of C/X = (ring circumference/wavelength). It is found that transverse focussing (represented by the tune Q) and superperiodic lattice geometry (represented by the number of FODO cells N) can resonantly am plify the closed orbit response to certain frequencies. As a consequence, as C/X increases through some values mN ± 0 (m positive integer), the response function is expected to show a steplike behaviour followed by a slow fall off. The results are compared with models which have both continuous focussing and uncorrelated quadrupole motion. Numerical examples are presented.


This study examines conflicts over job classification and over the use of seniority (job-classification politics) in two work settings-a midwestern plant of an electronics company and the longshore industry of southern California. Two phenomena characterized job-classification politics in each setting-hoarding, that is, the erection of barriers around jobs, and fragmenting, that is, the erection of barriers between workers. These outcomes are attributed to an unusually strong demand for skilled workers and to worker resentment over violations of seniority. The results are interpreted from an organizational-politics perspective.

Abstract. At present, the federal government is actively urging its public service managers to do four things: 1/ take firm control of public service activities in seeking 'value for money' productivity; 2/ accept responsibility for the timeliness and quality of the services they provide to their special publics; 3/ take positive steps toward upgrading their competence as managers and, within these steps, to develop and display a professional integrity and commitment to managing; and 4/ support moves toward a system of accountable management, built around the concept of up-the-line responsibility.

Developing his position from the Friedrich-Finer debate of the early 1940s, the author states there are strong tensions inherent in such a mix of expectations. He further states that the initiatives giving rise to the expectations are confronting a public service inadequately prepared to respond, with the possible consequences of a most adverse effect on public service morale. The paper seeks to help managers cope with the new challenges through clarifying the nature of the initiatives and presenting an approach designed to bring accountability and responsiveness into manageable harmony.

Sommaire. En ce moment, le gouvernement federal encourage les gestionnaires a faire quatre choses: 1/ exercer un controle ferme des activites de la fonction publique afin de stimuler la productivite 2/ accepter la responsabilite de ľa-propos et de la qualite des services offerts a leur clientele; 3/ prendre les mesures appropriees afin ďameliorer leur competence comme gestionnaires et, par ces demarches, developper leur integrite professionnelle et leur engagement comme administrateur; et 4/ appuyer leurs demarches en vue ďun systeme responsable de gestion, base sur le concept de la responsabilite.

En developpant sa facon de voir a partir de debats Friedrich-Finer depuis le debut des annees 40, ľauteur constate qu'il y a de fortes tensions inherentes a un tel melange ďattentes. II constate, de plus, que la fonction publique n'est pas preparee adequatement a repondre a ces initiatives, une telle situation pouvant susciter des effets nefastes sur le moral de la fonction publique. ľarticle se propose ďaider les gestionnaires a faire face a ces nouveaux defis en clarifiant la nature des initiatives suggeiees. ľarticle suggere une approche pouvant faciliter ľharmonie entre responsabilite et flexibilite.

Models in testing are important for describing, understanding, and managing tests. In the automotive domain, AUTOSAR is an important standard to model components of electronic control units. AUTOSAR, however, lacks information about tests or test scenarios. Early testing in the automotive domain is often done by Model-in-the-Loop simulation. Simulations of several components are run in different environments, each. Thus, they need to be connected (co-simulated) for integration testing of these components, e.g., via simulator coupling. This paper is focused on closing the gap between AUTOSAR models and co-simulation-based test scenarios that use simulator coupling. Our main contribution is the definition of a modeling language to describe test environments. The instances of this language can be derived from existing AUTOSAR models and can also be used to automatically generate co-simulation-based test environments. Furthermore, we provide a workflow to integrate this model in the engineering process and an experiment report to demonstrate the applicability and the advantages of the approach.


In this paper, the trajectory optimization of alpine skiing is studied based on Radau pseudospectral method (RPM). First, the kinetic model of alpine skiing is established by Newton's second law, then the boundary constraints are considered, and the trajectory optimization of alpine skiing is converted into the optimal control problem which takes the minimum time consumption as the cost function. Finally, the optimal control problem is transcribed to a nonlinear programming problem (NLP) by RPM, and the optimal solution is obtained. Simulation results show that RPM can effectively generate a continuous optimal path meet the requirement of accuracy.

The present investigation was carried out with the purpose of evaluating the incidence of the Administrative-Financial Management in the profitability of the company "Muebles Metalicos Ardey", of the city of Santo Domingo, year 2015, the study allowed to provide the perspectives necessary for the Take the necessary measures to benefit the economic growth of the entity. Three objectives were set out to achieve the desired purpose such as; Diagnose the Administrative-Financial Management used by the company to manage resources, determine the level of training of staff in productive development and analyze the Administrative-Financial Management through the application of financial indicators. In order to support the work done, it was indispensable to cite authors who refer to the subject under study, the same ones that were obtained from books, theses and web pages, and presented in the conceptual and theoretical foundation. To obtain the primary and secondary information it was necessary to apply types, methods, instruments, population and research sample. In the third part, the results of each of the proposed objectives were carried out, in such a way as to clarify doubts about the decisions made by the managers in favor of the organization. The results showed that the company does not have a structural and functional organization chart, as well as policies and procedures that are fully documented, that is to say that they manage an empirical structure, on the other hand, it fails to comply with budgetary planning because it lacks supervision and control . As for the training, the results showed that the entity does not provide this benefit for 96% of the operational employees, the only beneficiaries are the department heads, which is why the level is low for business development. The indicators of Administrative and Financial Management showed that "Muebles Metalicos Ardey" has an average level of control and that they require more attention, that is why the profitability indicators show that the assets are compromised by 45.90% with respect to the Total liabilities, on the other hand it was estimated that equity reached a net income of $27.52. The company has enough potential to grow in the market, what it needs to grow is to improve organizational bases and better focus its business objectives.


In the great international literature on comparative constitutional law, main theoretical observations and constructions normally been made on the ground of principle Western models interpretation. That is quite natural because the experience of established democracies in their historical and political implications formed the basis and resource of inspiration for many new nations looking forward to create the similar forms of constitutional government in spite of various cultural and social difficulties. But this approach substitute the problem by its ideal solution sometimes ignoring the whole bulk of emotions, hesitations, exaggerated hops, disappointments and interests, which are represented in regions and countries of so-called "periphery zone" of legal development acutely pressed to search their own strategy of constitutional modernization in quite different cultural and political context. This problem becomes the central point in the monumental work under review – "The Oxford handbook of Caribbean Constitutions". The book providing a solid ground for the complex academic deliberation of one of such regions – a very specific group of countries, which formerly were part of the great European colonial empires, recently proclaimed their independence and stay in a permanent process of constitutional self-determination trying to find their proper way in legal globalization. Carefully summarizing the materials and ideas of this collective work, the author of this review article discusses some general conceptual items of this type of constitutionalism: the role of common culture and history in pre-colonial, colonial and post-colonial legal development; the impact of "colonial legacy" in formation of post-independence constitutionalism of respective countries. He reconsider the place of indigenous forms and imported imperial constitutional design in the establishment of the new constitutionalism and administrative governance; the specific trend to hybridization of different legal traditions, norms and institutes in process of their evolution and selection through constitutional amendments, constitutional jurisprudence and projects of reforms. In concluding part of this article the author summing up his vision of continuity and ruptures in legal development balance of Caribbean region in comparison with Post-Soviet region's current constitutional transformation.


Background: Skin is exposed to a vast variety of chemicals, organic or biological products among fashion seeking community of today's world. This put them at risk of contact sensitization. Rapid industrialization, westernization of the society and poor labeling laws of cosmetics put us to the threat of "contact sensitization explosion" in near future. To know the drift of common contact sensitizers in the region, patch testing provides an insight into the cause of allergic contact dermatitis. The objective of the study was to determine the commonest allergen responsible for allergic contact dermatitis among patients attending contact dermatitis clinic in a tertiary care hospital.Methods: This retrospective study was conducted in the Department of Dermatology of our institution. We reviewed the medical records of all patients who were patch tested over a period of 6 years, using Indian standard series.Results: A total of 521 patients who were patch tested in the contact dermatitis clinic were included in the study. Nine patients with angry back were excluded. There were 269 males and 243 females. The commonest provisional diagnosis was allergic contact dermatitis secondary to hair dye in 172 (33.3%) patients followed by air borne contact dermatitis to parthenium in 88 (17.3%) patients. The paraphenylenediamine (PPD) being the most common sensitizer in 92 (17.9%) patients was followed by nickel in 86 (16.7%) patients, potassium dichromate in 36 (7%), parthenium in 32 (6%) and fragrance mix in 31 (6%) patients.Conclusions: This study revealed higher prevalence of hair dye dermatitis. Paraphenylenediamine was the most common allergen.


This paper discusses the devastating effects of tsunamis on the Crescent City Harbor District's marina and the District's efforts to recover from the tsunami and replace the marina with a new tsunami resistant marina. The main marina in the harbor at Crescent City, California was badly damaged by a tsunami in 2006. Rather than simply rush to "put back the marina the way it was," the District elected to design a replacement harbor to be as tsunami resistant as feasible. While the design process was underway, the March 2011 tsunami struck the harbor, hurt the fishing industry and threatened the local economy. The 2006 and 2011 tsunamis caused about $50 million damage to the waterfront structures and navigable waterways at Crescent City. The local fishing community marina was severely damaged and required replacement. The occurrence of two tsunamis so close together in time illustrates the importance of including tsunami effects on the design of this marina. Marinas are historically designed to resist operational vessel loads due to berthing, wind, wave, and current. The Crescent City marina is the first marina designed specifically to resist a significant tsunami wave. The author and his colleagues discuss the harbor damage from tsunamis, the emergency response plan, the design approach for the replacement marina and rock slope protection, the regulatory, permitting, and anticipated construction issues. The design process includes geotechnical constraints, hydrodynamic analyses, and float and pile design. This paper also discusses the cost effective means to optimize float and pile design, improve the recovery time for future tsunami damage, tsunami design lessons learned, and a path forward for future marina tsunami design. BACKGROUND Crescent City is located in northern California near the Oregon state border. The port had its beginnings in 1855, with the first wharf built on Whaler Island followed by initial construction of the Outer Breakwater by the Corps of Engineers in 1920 and the Inner Harbor and Marina in 1972. Commercial and sport fishing boats operate out


Simultaneous Localization and Mapping (SLAM) problem is a very popular research area in robotic applications. EKF-SLAM and FastSLAM are widely used algorithms for SLAM problem. The greatest advantage of FastSLAM over EKF-SLAM is that it reduces the quadratic complexity of EKF-SLAM. On the other hand, increasing number of estimated landmarks naturally slows down the operation of FastSLAM. In this paper, we propose a new method called as Intelligent Data Association-SLAM (IDA-SLAM) which reduces this slowing down problem. In data association step also known as likelihood estimation, IDA-SLAM skips comparing a new landmark with all of the pre-calculated landmarks. Instead of this, it compares the newly found one with only nearby landmarks that was found previously. The simulation results indicate that the proposed algorithm significantly speeds up the operation of SLAM without a loss of state estimation accuracy. Real world experiments which have been performed in two different scenarios verify the simulation results. A runtime reduction of 43% and 52% is observed respectively for each of the test environments.


Let k be a field of characteristic p and G a finite subgroup of GL(V) where V is a finite dimensional vector space over k. Then G acts naturally on the symmetric algebra k[V] of V. We denote by k[V]G the subring of k[V] consisting of all invariant polynomials under this action of G. The following theorem is well known. Theorem 1.1 (Chevalley-Serre, cf. [1, 2, 3]). Assume that p = 0 or (|G|, p) = 1. Then k[V]G is a polynomial ring if and only if G is generated by pseudo-reflections in GL(V).


Hydropower is a significant contributor to the renewable power generation sector, but the energy in tidal currents is not commonly used to generate electricity. This is due to the relatively slow speed of tidal currents which does not allow for the economic development of underwater turbines in tidal regions. This paper investigates whether it is possible to increase locally the current speed in regions where the tidal current is normally not strong enough to generate significant power. The device proposed to increase current speed is composed of an arrangement of vertical walls made of poles supporting a thin membrane with suitable profile, referred to as Tidal Current Accelerating Structure or TCAS. Current turbines are to be placed in areas of accelerated flow to convert the current energy into electricity. In this paper, results of model tests that were performed to quantify the ability to increase current speed are discussed. It was found that the increase in flow velocity was not as significant as expected, probably due to interactions between the turbines and the current accelerating devices. Recall potential theory's flow speed around a disk yields a velocity factor increase of 2 at 90 degrees from the stagnation point.© 2007 ASME


Objective: This research was performed to assess the quality of different marketed tablets having mefenamic acid (500 mg). The selected tablets are produced by numerous companies and presented in the Iraqi pharmaceutical marketplace.
Methods: Different batches of mefenamic acid conventional tablets were exposed for several tests of quality control. These evaluation tests include hardness, weight variation, friability, disintegration time, drug content, and drug dissolution profile. The properties of these quality tests were made conferring to the specification of USP-pharmacopeia.
Results: The data of this study indicate that each tablet of mefenamic acid batches conformed to the requirement of USP pharmacopeia, the hardness was (6.87-8.06 Kg/cm2), and the drug content results were (90.666-99.214%) within USP limitation. The data of disintegration time and weight uniformity were agreeable with pharmacopeia and the in vitro release assay showed that the release of each mefenamic acid marketed tablet was highest than (80 %) in 45 min, which reproducing compliance with the USP pharmacopeia's limitation.
Conclusion: From this study, it was proved that all of the marketed brands of mefenamic acid tablets meet the standard character in the USP pharmacopeia for in vitro quality control tests.


The increasing importance of liquid composite molding (LCM) techniques in the composites industry requires the development of adequate methods for characterizing the permeability of reinforcing textiles. This enables the comparison of flow simulations with real impregnation experiments as well as the prediction of the impregnation behavior for industrial applications. For flat fiber reinforcements numerous approaches for oneor multidimensional RTM-based permeability measurements are known. However, permeability characterization of tubular braidings used for infusion-based bladder inflation molding (BIM/RTM) requires the development of an alternative concept. In this work, a novel approach for measuring the one-dimensional unsaturated in-plane permeability of tubular braided textiles is introduced. The approach involves a robust mechanical setup, an industrial camera system and a fully automated testing procedure with specifically developed digital image processing algorithms. This enables the automatic detection of the advancing fluid flow front during testing at a high level of repeatability. As the impregnation behavior of the braided sleevings predominantly shows unidirectional characteristics, the permeability is evaluated by using the one-dimensional form of Darcy's equation for steady state flow in a porous medium. The infusion-based bladder inflation molding process is influenced by various process parameters. The compaction pressure during impregnation, which primarily depends on the ratio between injection pressure and internal bladder pressure, is one of the most crucial parameters because it severely affects both laminate quality and fiber volume content. In this paper, the results of measurements investigating the influence of the compaction pressure as well as the interdependence of bladder and injection pressure on the in-plane permeability of a biaxial braided carbon sleeving are presented. The analysis shows that an increasing compaction pressure significantly reduces the textile permeability, while a minimum compaction of the preform should be maintained to avoid unwanted effects such as fiber washout and overfilling of the preform.

We experimentally characterize the non-equilibrium, room-temperature magnetization dynamics of a spin chain evolving under an effective double-quantum (DQ) Hamiltonian. We show that the Liouville space operators corresponding to the magnetization and the two-spin correlations evolve 90 degrees out of phase with each other, and drive the transport dynamics. For a nearest-neighbor-coupled N-spin chain, the dynamics are found to be restricted to a Liouville operator space whose dimension scales only as N2, leading to a slow growth of multi-spin correlations. Even though long-range couplings are present in the real system, we find excellent agreement between the analytical predictions and our experimental results, confirming that leakage out of the restricted Liouville space is slow on the timescales investigated. Our results indicate that the group velocity of the magnetization is 6.04 ± 0.38 μm s−1, corresponding to a coherent transport over N ≈ 26 spins on the experimental timescale. As the DQ Hamiltonian is related to the standard one-dimensional XX Hamiltonian by a similarity transform, our results can be directly extended to XX quantum spin chains, which have been extensively studied in the context of both quantum magnetism and quantum information processing.


Feature Reduction is the reduction of features. Most of the intrusion detection approaches focused on feature selection issues such as irrelevancy, redundancy and length of detection process. These issues will degrade the performance of system. The performance of the system is improved by three feature selection methods involving correlation based feature selection, Gain Ratio and Information Gain. The threshold based Naive feature reduction algorithm is used to reduce the features. The reduced features are further classified by Naive Bayes classifier to produce best performance to design Intrusion Detection System. Index Terms – Feature selection, classification, Feature reduction, Intrusion detection.

Abstract This article investigates Maimonides's ethos of disclosing "secrets" and explores its Islamic origins, focusing on sources neglected by earlier scholarship concerning the Guide of the Perplexed. I turn from the prevalent method by which the Guide has been studied for decades, namely, as a work at the core of which lie strategies and an ethos of concealment. In lieu of the conventional method, I go in a very different direction by inquiring into the modes that Maimonides used in fashioning his Guide as a work that involves a self-proclaimed exceptional act of revelation of secrets and a breach of the boundaries of concealment. The resulting textual investigation demonstrates that clusters of motifs presented in these sources, as well as structures of arguments, were retained in their cultural migration. This exploration allows me to illuminate new aspects of the question of the genre of Maimonides' Guide, its sources, and its author's intertextual art of writing.

The maturity and wide application of dual linear polarization radar technology puts forward higher requirements for the calibration method, accuracy and stability of dual polarization.The differential phase data tends to increase monotonically due to the cumulative effect of the radar beam passing through the rain zone, but the quality of the differential phase data is disturbed due to system noise and other external noise effects, which does not fully comply with this trend. In this paper, kalman filter optimization is performed on the original differential phase data of the dualpolarization radar, and then the quality-controlled of differential phase using a polynomial fitting algorithm.The test was conducted using observation data at 11:35 during the rain process on June 5, 2016. The test shows that: In Table 1, it can be seen that the original differential phase data difference fluctuation range of the adjacent distance library is: $( 8.9212 \sim7.5863)$, after the kalman filter, the difference fluctuation range is reduced to: $(- 0.1555 \sim0.2480)$,after the final superposition polynomial fitting, the fluctuation range is reduced to: $( 0.007 \sim0.088)$. 1.It can be seen that the differential phase exhibits a more stable increasing trend after 2-step filtering optimization; 2.After filtering, the differential phase and the differential phase shift rate are improved compared with those before filtering. The contours of a and b in Fig.4 are more consistent than before filtering; 3.The differential phase and differential phase shift rate high value region after filtering are basically consistent with the high value region after filtering are basically consistent with the high value region of the reflectivity in Fig.3(a); 4. The strong echo A and B in Fig.3(a) are also reflected in Fig.4; 5.It can be seen from Fig.5(b) that the filtered differential phase shift rate has a tendency to increase with the increase of the reflectivity factor after filtering, which is consistent with the relationship between the differential phase shift rate and the reflectivity.It is shown that using kalman filter algorithm is a feasible solution for the differential phase shift rate and the differential phase quality control.
