The vast amount of research that has been conducted on the problem of students dropping out of school shows that the causes and solutions are multifaceted. This situation demands extensive research in all dimensions of the problem and in particular in areas that would suggest a proactive approach to the problem. While in the past numerous studies have concentrated on causes external to the school, recently there have been calls for schools to examine internal influences on the dropping out process. It is the conviction of this research and supported in the literature that schools can prevent students from dropping out of school. Such prevention, however, requires early insights into the reality of school for students, especially for those who are showing signs of alienation from the school. The purpose of this study is to examine the differences in perceptions on selected aspects of school life, among sixth and seventh grade students classified as potential and non-potential school dropouts. -- Four research questions were posed in this study. These questions focused on the determination of significant differences between the two groups on perceptions of four aspects of school life, broadly defined as teachers, school discipline, school work, and school success. These four aspects were more specifically broken down into eleven school related variables. These variables were identified as: teacher attitudes, teacher behaviours, teacher expectations, effectiveness of school discipline, fairness of school discipline, interest of school work, relevance of school work, difficulty of school work, satisfaction with school work, expectations for school success, and opportunities for school success. Data were gathered by means of a Student Checklist which required both a frequency and an intensity response from students on perceptions. By statistical analysis, it was determined that significant differences existed in the frequency of perceptions between potential and non-potential school dropouts on all variables. It was also determined that significant differences occurred in intensity of perceptions but only on several variables, specifically, fairness of school discipline, difficulty of school work, and expectations for school success. -- The fact that potential school dropouts in this study hold more negative perceptions of school long before they decide to drop out has implications for the prevention of dropping out for schools. Knowledge that students who have been identified to be at risk of dropping out hold significantly more negative perceptions of school than other students, could stimulate educators to re-examine their responses to those students in an effort to strengthen their bonds with the school.


Summary Load carrying fillet-welded cruciform joints have two fatigue crack initiation points. They are located in the weld toes and weld roots where high stress concentrations occur. Which of the two serves as the initiation point depends on the weld leg length, plate thickness, and weld penetration, and the mechanism concerned is easily understood. Some experimental results indicate that the fatigue crack initiation point is also affected by the magnitude of the stress range. The reason for this phenomenon remains rather obscure. To establish this reason, the present research study is intended to clarify the relationship between the stress range level and fatigue crack initiation point changes and to quantify the effects of the weld leg length and penetration depth on the fatigue crack initiation point. Fatigue tests of welded joint specimens, thermal elastic-plastic finite element method (FEM) analyses of welding residual stresses and fatigue crack propagation analyses considering the residual stress a...

In the German photovoltaic industry, which in its first decades was characterized by a slow evolution, demand triggered by public policy not only increased market volume, but ultimately led to a shakeout in the number of producers. We discuss the evolution of this industry considering a model of industry evolution. Demand inducing policy will be discussed as possible trigger of industry life cycle development. The findings suggest that these instruments can take the same effect as a technical advance to trigger the growth of an industry as well as a shakeout in the number of active producers.


An alternate negative tone resist is investigated for advanced lithography. Unlike conventional negative tone development (NTD) resists developed with organic solvent, this negative resist use TMAH as its developer. Thermal acid generator (TAG) and photo base generator (PBG) are proposed for this resist. PBG decomposes and generates alkali at the exposed area and neutralizes the acid from TAG. Hence, positive resist can produce negative tone image (NTI), and gain better optical contrast than positive tone imaging. The new negative resist reported in this paper also shows better resolution than conventional negative resist. Several optimization studies are also reported. In addition, major limitations on further improving resist resolution are also pointed out in this paper. The solution proposed has been proven workable from experimental results. This opens the possibility to combine better optical contrast from NTI, high resist resolution from positive resist resin, and better development contrast from TMAH solution.


This review discusses the construction of all-carbon quaternary stereocenters using catalytic asymmetric conjugate addition and its application in natural product synthesis.


The densities and viscosities of six ternary mixtures of the water, monoalkanols; 1-propanol, 2-propanol and monoalkanoic acids; formic acid, acetic acid and propionic acid are determined over the entire range of composition at 298.15, 308.15 and 318.15 K. From the experimental observations, the viscous synergy and synergy interaction index are derived from the equations developed by Kalentunc-Gencer, Peleg and Howell, respectively. The speeds of the sound of these ternary mixtures have been measured over the whole composition range at the same temperatures, and also the excess molar volumes, the isentropic compressibilities and excess isentropic compressibilities have been evaluated from the experimental data.


A spray drying approach has been used to prepare polyurethane/multiwalled carbon nanotube (PU/MWCNT) composites. By using this method, the MWCNTs can be dispersed homogeneously in the PU matrix in an attempt to improve the mechanical properties of the nanocomposites. The morphology of the resulting PU/MWCNT composites was investigated by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). SEM and TEM observations illustrate that the MWCNTs are dispersed finely and uniformly in the PU matrix. X-ray diffraction results indicate that the microphase separation structure of the PU is slightly affected by the presence of the MWCNTs. The mechanical properties such as tensile strength, tensile modulus, elongation at break, and hardness of the nanocomposites were studied. The electrical and the thermal conductivity of the nanocomposites were also evaluated. The results show that both the electrical and the thermal conductivity increase with the increase of MWCNT loading. In addition, the percolation threshold value of the PU composites is significantly reduced to about 5 wt % because of the high aspect ratio of carbon nanotubes and exclusive effect of latex particles of PU emulsion in dispersion. © 2012 Wiley Periodicals, Inc.

The invention discloses a full-automatic grinding and cutting integrated multi-position machine, belonging to a special mechanical processing device which comprises a machine bed. A guide rail disc is fixed at the upper end of the middle of the machine bed; the guide rail disc is provided with a central rotary shaft and a big rotary disc which is provided with a working position rotary disc; a rough processing planar grinding head, a fine processing planar grinding head, a lateral slope dual grinding head and a middle groove-cutting grinding head on a motor are arranged at the periphery of the guide rail disc on the upper end of the machine bed. During working, the processed work piece is fixed on the working position disc which is driven by the big rotary disc to firstly process a rough surface grinding and then process a fine surface grinding. After the surface processing, a lateral surface process of grinding is followed, and after the lateral surface grinding process, a process of middle groove-cutting and grinding is followed. In this way, the utilization of mechanical rotation realizes a multi-procedure processing, thus avoiding clamping and transferring, and greatly saving the processing machinery and working time. More mainly, the utilization of the device can enable the enterprises to shift from a labor-intensive manufacturing to a technology-intensive manufacturing.


In many applications of percolation theory, checking the establishment of the spanning clump/cluster of overlapping particles that spans all over the field is an essential task. Given a percolation theory field modeled by two-dimensional lattice (matrix), in this paper, we present an algorithm which determines if there is a spanning clump in lattice or not. The spanning clump is the largest cluster in the field which that spans the entire network vertically, horizontally or both. Due to wide range of properties and applications of cellular automata such as simplicity and distributedness, we use them in our algorithm. The proposed algorithm is simple but yet useful and also could be run in a parallel / multicore machines. Also, the approach of the algorithm could be extended to higher dimensions.


ZnSe nanowires were grown onto Mo transmission electron microscopy (TEM) grids by MBE by suitably varying the growth parameters. In situ and high-resolution TEM studies were carried out to understand the structure, defects, and growth mechanism of this nanowire. The nanowire morphology is very sensitive to the growth parameters involved. Twin boundaries are the most commonly occurring defects in the nanowires grown under Zn-rich condition and catalytic gold particles of irregular shape are observed along the nanowire body. In the course of in situ heating the shape of the nanowire tip is observed to change at ∼178 °C. Definite growth of the nanowire starts at ∼235 °C. The diameter of the grown nanowire is almost equal to that of the catalyst gold particle present at the tip of the nanowire. In situ experimental observation and available phase-diagram information strongly suggests that nanowire growth should be possible with a solid catalyst particle though it does not rule out the possibility of the exist...

JFE Steel Corporation developed a technology for injection of hydrogen-based gas fuel in sintering machines, Super-SINTER (Secondary-fuel Injection Technology for Energy Reduction). The technology makes it possible to greatly reduce CO2 emissions in the sintering process, and was successfully applied to a commercial sinter plant for the first time in the world. In ordinary sintering process, after coke breeze is mixed with iron ore and limestone, raw materials are charged and sintered in sintering machine. In order to produce high strength and high reducibility sintered ore, it is necessary to keep the sintering temperature between 1,200 degrees and 1,400 degrees during sintering. In the temperature below 1,200 degrees, the strength of sintered ore decreases because raw materials do not melt enough. In the temperature over 1,400 degrees, the strength and reducibility decrease by increasing glassy silicate. With Super-SINTER technology, it is possible to extend the optimum temperature zone by injecting a hydrogen-based gas fuel from the upper side of the charged raw materials as a partial substitute for coke breeze. As a result, the energy efficiency of the sintering process was greatly improved, and it has been achieved to reduce CO2 emissions by a maximum of approximately 60,000 tons/year. Moreover, the new technology of hydrogen-based gas fuel injection with oxygen enrichment has been developed to furthermore improve Super-SINTER technology. This technology can extend the optimum temperature zone wider than ordinary Super-SINTER by increase of combustion rate of fuels with oxygen enrichment. As a result, sinter productivity with high quality was improved greatly.


This thesis presents in a specific way the methodology, application and results of the application of a neuro-diffuse control to track trajectories in a mobile robot of Ackermann type configuration. The difficulties for controlling this vehicle derive from its non-linearity and non-holonomy, as well as the characteristics of the environment in which it travels, for which the CARSIM tool is used, thus achieving the simulation of the vehicle, displacement and environment. To solve the problem of tracking previously defined trajectories, it proposes a neurodiffuse controller of the Sugeno type, which is previously fed with the geometry of the path to follow, and is fed back with the outputs of the variables: Area error and Lateral distance error, estimated from the 5 sensors with which the vehicle is specified within the CARSIM program, as well as reliable data about its position and orientation with respect to a local positioning system of the software used. The proposed controller is based on a set of rules of the Sugeno type that relate 2 input variables: "Area error" and "Side distance error", with one output variable: "Front axle rotation angle", being the first of the Gaussian type and the linear type output. The effectiveness of the controller is evaluated by analyzing the average error in tracking paths with different geometries.


Higher education institutions are called to expand their role and responsibilities, by enhancing their entrepreneurial mindset and redefining relationships with stakeholders. In order to cope with these new challenges, they have started to operate in a strategic manner, by performing marketing and merchandising activities. Indeed, in a sector characterized by the presence of competitive funding models, several forms of accountability, and performance indicators, universities have become open systems and have started to operate like enterprises, considering students as customers. Given this premise, the aim of the paper is to individuate marketing and merchandising strategies in higher education and to evaluate their effectiveness in order to foster stakeholders engagement. This is in line with the entrepreneurial university model that represents the starting point of the theoretical study, then a literature review of "marketization" in higher education institutions is presented, showing how this field is not yet completely investigated. Data refer to the Italian context and are analyzed through a qualitative method. Findings suggest that most Italian universities perform merchandising strategies, but currently there is not sufficient information to evaluate their effectiveness in higher education, it was only possible to make hypotheses.

The quality of electricity supply is determined by three main parameters, namely availability (continuity of supply), voltage quality, and speed and accuracy of customer service. This paper will discuss the two main parameters mentioned, which are reliability and power quality. The increased usage of rooftop solar PV potentially improves the reliability of the system. With the increasing penetration of VRE in distribution systems, restoration of remote distribution feeder power in an emergency is likely to be carried out with the support of a rooftop PV. The available power from the renewable DG unit ensures the recovery of the more affected customers, increasing overall system reliability especially the SAIFI and CAIDI. This paper elucidates that the reliability distribution network has the potential to get improved with the power supply from the rooftop PV and vehicle to grid (V2G) mode of the PEV. However, the presence of rooftop PV and PEV in the distribution network also harms the voltage regulation, where during the day the voltage tends to fluctuate according to the power supply from the PV rooftop, and at night the voltage tends to decrease along with the charging mode of the PEV. In the case of a long-distance 20 kV distribution network with voltage drops at the end, the presence of PV could repair this problem, but the opposite happens in the presence of PEV. Some simulations were performed to analyze the impact of PV and PEV in a distribution network model, especially for the voltage regulation.


This study aimed to analyze the cause of declined semen quality in diabetic patients. A total of 157 participants were enrolled and divided into the normal group (n=70), fasting glucose impaired group (n=58) and diabetic group (n=29) based on their fasting glucose levels. Semen samples and serum samples were collected. Conventional semen parameters, including sperm concentration (SC), total sperm count (TSC) and progressive motility (PR%), were measured. Superoxide dismutase (SOD), malondialdehyde (MDA), interleukin-6 (IL-6), Tumor necrosis factor-α (TNF-α), Leptin (LEP), Zinc-alpha 2 glycoprotein (ZAG), adiponectin (ADPN) and α-glucosidase levels were determined by ELISA. Fructose and zinc levels were measured by colorimetry. Hormone levels were determined by chemiluminescence immunoassay. Compared to the normal group, the diabetic group showed significantly decreased sperm concentration, total sperm count PR%, and ZAG levels (P<0.05), increased FSH and LH levels (P<0.05), decreased T level (P<0.05), increased serum and seminal plasma MDA level (P<0.05), decreased SOD level (P<0.05), and increased seminal plasma IL-6 level (P<0.05), as well as significantly increased seminal plasma α-glucosidase, zinc and fructose levels (P<0.05). The fasting glucose impaired group showed decreased sperm PR% (P<0.05), and there was no statistical difference in the other test indexes. The decline of semen quality in diabetes patients is caused by many factors, including oxidative stress, inflammatory reactions, endocrine disorders, insulin resistance and other factors. Fertility guidance and treatment for diabetic patients requires comprehensive consideration.

Since 1991, the students enrolled in the Electrical Engineering and Computer Engineering Departments at San Jose State University have had an experimental course in engineering design and computer tools. In the Fall of 1994, the College of Engineering adopted the course as a required two-unit course (one unit lecture and three hours laboratory work per week) for all engineering students. The course is divided into three parts. The first covers the disassembly and reassembly of a computer peripheral, a report on the operation of the device and one improvement to add value. The second uses spreadsheets (either Lotus or Excel) to aid in the mathematical solution of an engineering problem. The third part uses Matlab to solve the mathematics of an engineering problem. The emphasis in the course is in defining the engineering solution for a particular engineering problem, using the computer packages to analyze the input variables, and then presenting the data so that "everyone" will come to the same conclusion. We use a data acquisition system with a computer system to generate data for the various student projects. All projects are conducted by teams of three students. All grades, except two for class exams, are team grades. The student projects are chosen from a list generated by the course faculty and other faculty in the College of Engineering.


There is growing attention for developing professional learning experiences for content area teachers to infuse computational thinking (CT). However, there is little reporting on how teachers continue to implement the CT lessons once professional development (PD) is over. This study provides initial results on our efforts of building project sustainability through teacher autonomy in designing their own CT infusion projects or PDs for their schools. Our initial analysis indicates the need to continue to build teacher autonomy within the professional learning experiences for developing teacher confidence and sustainability of the project.


Planning and design of land consolidation was an important part of the layout of farmland water conservancy projects,and the layout of farmland water conservancy project was based on the analysis of the water balance.Therefore,the water balance of land consolidation directly related to the scientific character of planning and design of land consolidation.Water supply could be analyzed from water supply capacity of the project area and the use of surface runoff coefficient.Water demand could be analyzed from the cultivation of crops,irrigation guarantee rate,replanting index and scale irrigation.So whether or not to take measures to ensure that water supply was more than water demand to meet the irrigation requirements was determined.In this paper,Fushun County,Sichuan Fu Shan town land consolidation project as an example,the main factors of water balance analysis could play a reference on land distribution of farmland water conservancy projects.


Conventional tagging data has documented long distance movements (including trans-Atlantic movements) in blue marlin (Makaira nigricans) and yellowfin tuna (Thunnus albacares) within the Atlantic. Swordfish (Xiphius gladius) have also been shown to move substantial distances, although primarily in a north-south direction. There is, however, a paucity of data for wahoo (Acanthocybium solandri). In the past several years, electronic archival (i.e., data recording) tags have significantly advanced our understanding of the behavior and movement patterns of large pelagic fishes. Data from electronic archival tags have generally corroborated conventional tagging data with respect to long distance movements, as well as the daily vertical movement patterns previously obtained through acoustic telemetry. Taken together, it is now possible to define "habitat envelopes" for pelagic species and to correct nominal catch rates for changes in gear vulnerability due to differences in gear targeting. In general, there is a broad spectrum of vertical movement patterns: blue marlin and yellowfin tuna generally remain within the uniform temperature surface layer (although blue marlin occasionally descend to below 300 m), wahoo have less vertical range and appear to remain above 50 m most of the time, whereas swordfish mirror the vertical movements of the organisms of the deep-scattering layer remaining within about 20–30 m of the surface at night but descending to 700–800 m during the day. Tagging data demonstrates that many large pelagic fish species move through the waters of other jurisdictions thus requiring a regional and international approach to assessment and management. The primary organization which undertakes this function in the Atlantic Ocean is the International Commission for the Conservation of Atlantic Tunas (ICCAT), which is responsible for the assessment and management of tunas, swordfish and billfishes.

Objective. A novel parameter acquired from conventional B‐mode sonographic videos was introduced in this study, and its diagnostic accuracy for evaluation of hepatic fibrosis was investigated. Methods. Twenty‐eight patients with chronic hepatitis B and 8 patients with hepatic cysts in the right lobe (controls) were enrolled. B‐mode sonographic videos of hepatic motion under the ensisternum in the sagittal plane were captured during peaceful breathing. Maximal accumulative respiration strain (MARS) values of hepatic tissue were obtained after image analysis. METAVIR scoring after liver biopsy was considered the standard. First, the relationship between MARS and the fibrotic stage was studied; and second, receiver operating characteristic (ROC) curves were used to assess the accuracy of MARS for evaluation of the fibrotic stage. Results. When the transducer was placed in the sagittal imaging plane under the ensisternum during the whole respiratory period, the hepatic tissue motion was almost in the same plane. The MARS values (mean ± SD) were 29.44% ± 10.44% in the F0 group (no fibrosis; n = 8), 19.30% ± 9.10% in the F1 group (portal fibrosis without septa; n = 8), 18.09% ± 7.36% in the F2–F3 group (portal fibrosis with few septa or numerous septa without cirrhosis; n = 12), and 14.16% ± 4.18% in the F4 group (cirrhosis; n = 8). The Spearman correlation coefficient between MARS and the fibrotic stage was 0.516 (P = .001). The diagnostic accuracy rates, expressed as areas under the ROC curves, were 0.87 for mild fibrosis (F ≥ 1), 0.72 for substantial fibrosis (F ≥ 2), and 0.75 for cirrhosis (F = 4). Conclusions. Maximal accumulative respiration strain attained from B‐mode sonographic videos of hepatic tissue is a new, convenient, economical, and promising noninvasive parameter for assessment of hepatic fibrosis in patients with chronic hepatitis B.


Abstract:
Background: The most frequent movement issue seen in clinical practice is tremors. It is known as repetitive, involuntary oscillations. The diagnostic process for tremor patients can be time-consuming and complicated, as the identification of "Essential Tremor" and its distinction from other types of tremor.
Objectives: This study aimed to describe the electrophysiological findings of essential, enhanced physiological, and physiological tremors, using surface electromyography and an accelerometer.
Patients and Methods: The study included 24 patients with essential tremors, 10 patients with enhanced physiological tremors, and 10 patients with physiological tremors. We assessed the frequency, amplitude, and muscular contraction pattern of tremors during rest, posture, and a 1 kg load.
 Results: The tremor frequency of essential tremor patients was about 4.2-10.1 Hertz, while enhanced physiological tremor and physiological tremor were increased to 6.1–12.7 Hertz and 5.1-10.2 Hertz, respectively. The essential tremor group muscle contraction pattern was predominantly synchronous, as do all enhanced physiological, and physiological tremor patients, but with more fine low amplitude muscle bursts. By varying the tremor frequency and the weight load effect, tremor analysis could discriminate essential from enhanced physiological, and physiological tremors.
Conclusions: The tremor analysis using surface electromyography and an accelerometer is sufficient to differentiate between essential tremors, enhanced physiological tremors, and physiological tremors.


Abstract This paper is concerned with n–localization property introduced by Newelski and Roslanowski in [10] and getting it for CS iterations of forcing notions.


Conversations are sequences of messages exchanged between interacting software agents. For conversations to be meaningful, agents ought to follow conversational principles governing the exchange of messages at any point in a conversation. These principles must be defined in publicly verifiable terms (if they are to be used in open environments) and must allow the composition of flexible conversations (if they are to account for the context in which they occur). The main contribution of this thesis is to define a unified model for conversations for action that fulfills these requirements. The conversational principle in this model is the negotiation of shared social commitments, which entails the adoption and discard of obligations to act. This principle is encoded using conversation policies, which govern the form of conversations according to the observable state of interacting agents. The applicability of this model is illustrated through the modelling of two example conversations: one on the Contract Net Protocol, and the second on an electronic bookstore scenario.


Cloud providers face so many decision problems when offering Infrastructure as a Service to their customers. A major challenging problem for cloud providers is scheming efficient mechanisms for virtual machine provisioning and allocation. Those mechanisms enable the cloud providers to effectively utilize their available resources and obtain higher profits. Freshly, cloud providers have introduced auction-based models for virtual machine provisioning and allocation which allow users to submit bids for their requested virtual machines. In this paper, dynamic virtual machine provisioning and allocation problem formulated for the auction-based model considering multiple types of resources. Then truthful greedy mechanisms designed for the problem such that the cloud provider provisions virtual machines based on the requests of the winning users and determines their payments. Proposed mechanisms are truthful, that is, the users do not have incentives to influence the system by lying about their requested bundles of virtual machine instances and their valuations. Proposed mechanisms will achieve promising results in terms of revenue for the cloud provider.


Generation of REV1 mouse. Zygotes isolated from C57BL/6N mice were co-injected with in vitro transcribed Cas9 mRNAs and sgRNAs (target sequences AGAAATCTAATGATGTTGCATGG and TGAAGCACTGATTGACGTCACGG, designed using the crispr.mit.edu tool). The first sgRNA targets Cas9 to exon 4 of the Rev1 locus (ENSMUSE00000155622) and the second sgRNA targets Cas9 to exon 11 of the Rev1 locus (ENSMUSE00000155613). Offspring was tested by PCR for Rev1 inactivating mutations using the primers (FW: GGCAACATGGCCAAGAAGAAC, Rv1: ACTCAGTCAGCAGACACATGC, Rv2: TTATTCAGCTTGGCGAGCGCTTTTG) and ABI sequencing (3730 DNA analyzer, Applied Biosystems). A Rev1 mutant, carrying a 4800 bp deletion (1514 bp in cDNA) was selected, crossed three times onto C57BL/6J and maintained heterozygous. For genotyping the wild-type and mutant alleles are distinguished by size differences. Experiments were approved by an independent animal ethics committee of the Netherlands Cancer Institute (Amsterdam, Netherlands) (DEC number 13007) and executed according national and European guidelines.

An experimental study is performed to quantify the growth of the mixing zone in miscible viscous fingering. Rectilinear flow displacement experiments are performed in a Hele-Shaw cell over a wide range of viscosity ratios (1–1225) by injecting water into glycerol solutions at different flow rates. All the experiments are performed at high Peclet numbers and linear growth in mixing zone is observed. The mixing zone velocity increases with the viscosity ratio up to viscosity ratios of 340 and the trend is consistent with Koval's model. However, at higher viscosity ratios, the mixing velocity plateaus signifying no further effect of viscosity contrast on the growth of mixing zone. The front (fingertip) velocities also increase up to viscosity ratios of 340 above which the velocities plateau.

This article investigates the nature of Thomas Browne's method of scientific enquiry. It will make comparisons between Bacon's experimental method and the theological and patristic traditions, with particular regard to the problem and definition of error. Browne was convinced that reason and faith, and nature and religion, were in a relation of cooperation, and shared not only the same origin but the same end, that of God and truth. In light of this, Browne's use of mutually integrated theological and scientific sources is analyzed to shed some light on the problem of his idiosyncratic notion of experimentalism. The article ultimately attempts to demonstrate that Browne's method for enquiry was indeed experimental because of the way he investigated theological issues through the collection of data from nature and traditional scriptural materials.


With the number of implantable devices that utilize electronics increasing, there is an increasing need to find alternative ways of powering them. Currently, surgery is required to replace a battery for these devices; however, with advancements in Wireless Power Transfer (WPT) methods, the need for further surgeries will become negated. This paper explores the ability of WPT as an alternative powering method by investigating rectifier Power Conversion Efficiency (PCE). The rectifier converts high frequency waves to Direct Current (DC) energy that can provide usable power to devices requiring electrical power. It is targeted for low power applications centered around a 233 MHz fundamental frequency, and the rectification circuit was designed and simulated in Advanced Design Systems (ADS) following the shunt diode circuit topology. The rectifier has a measured peak efficiency of 59.4% at -3 dBm and displays efficiencies above 40% from -22 dBm up until diode breakdown. This device will provide a constant DC power source for use in powering devices wirelessly at low power.

Overall Conclusions


Aim: A fixed combination of thyme (THY) and ivy extracts (Bronchipret ® syrup (BRO)) is used for the treatment of acute bronchitis. Combining in vivo and mechanistic in vitro studies we aimed to provide a better understanding of the therapeutic potential of BRO on key aspects of acute bronchitis and to identify potential mechanisms of action. Methods: Bronchoalveolitis in rats was induced by intratracheal LPS instillation. BRO was given p.o. daily at 1-10-fold equivalents of the human daily dose. Animals were sacrificed up to 72 h post LPS challenge to analyze lung inflammation, goblet cell numbers and MUC5AC expression. Inhibitory effects of BRO on leukotriene production were determined in human neutrophils and monocytes as well as on isolated 5-lipoxygenase (5-LO). Inhibition of isolated phosphodiesterase 4B (PDE4B) activity was determined radiometrically. Results: BRO significantly reversed the LPS-induced increase in goblet cell numbers and MUC5AC expression. It furthermore reduced interleukin (IL)-1β, IL-6 and prostaglandin E 2 levels in bronchoalveolar lavage fluid. BRO and THY suppressed cellular release of LTB 4 (IC 50 = 40 and 25 μg/mL) and cysLT (IC 50 = 8 and 12 μg/mL) and inhibited the activity of isolated 5-LO (IC 50 = 20 and 12 μg/mL). PDE4B activity was also blocked by BRO and THY with IC 50 = 24 and 33 µg/mL. Conclusion: A herbal medicinal product containing a combination of thyme and ivy extracts (Bronchipret ® ) exerts anti-inflammatory and mucus-normalizing effects in LPS-induced bronchoalveolitis in vivo , potentially via inhibition of 5-LO and PDE4 activities. These effects may contribute to the observed clinical efficacy in acute bronchitis.


Burning fossil fuels to produce energy has been an essential driver in economic activities for around two centuries. Recently, despite the relatively still growing fossil-fuels consumption, renewable energy sources are being adopted and their share is rising with a higher rate. For the sake of environmental and human health protection, countries are applying new policies to replace fossil fuels with renewables. Although these are valuable steps towards energy security and environmental sustainability, the timing and the intensity of such a switch could harm the economy. Literature on the subject is diverse and growing but it does not provide conclusive results. More specialized studies within specific characteristics may carry better insights. This study addresses the impact of renewable electricity on the economic growth in fossil-fuelsdependent countries whose share of renewables is noteworthy. The study includes panel data from six fossil-fuels net-exporting countries and eight net-importing countries over the period 1995-2019. The study applied unit root tests and co-integration tests that accounts for crosssection dependence and slope heterogeneity. Cross-section dependence has been found among importers but not in exporters. The variables in both models are integrated of order one I(1). Fully Modified Least Squares method uncovered that 1% increase in renewables will increase GDP per capita by 0.08% and 0.10% for exporters and importers respectively. (Dumitrescu & Hurlin, 2012) non-Granger causality test showed that renewables have a bidirectional causal effect on economic growth in exporting countries and importing countries. feedback hypothesis for exporters suggests the beneficial effect on the economy due to renewables adoption, hence it is recommended to increase their share. Also feedback hypothesis for importers infers that the economic growth has led to a higher renewables' usage, consequently, it is recommended to continue embracing economic growth which is eventually going to promote renewables. This ultimately will lead to achieve climate-change goals and reduce dependence on fuels imports as well.


— Gmelina arborea and Moringa oleifera (GMMO) leaf meal were combined at the ratio of 3:1 and included in the diets of Red Sokoto does at 0, 10, 20 and 30% to investigate the effect on dry matter intake, live weight and cost of feed in Digitaria smutsii hay based diets. Twenty-eight (28) growing Red Sokoto does aged between 6 and 7 months with average weight of 14.71±0.09 kg were randomly assigned to four treatments balanced for weight with seven does per treatment in a completely randomized design. The experimental diets were offered at 4% of body weight. Cost of feeding was studied to determine the cost effectiveness of GMMO leaf meal inclusion in the diets. Results indicated that inclusion of GMMO leaf meal significantly (P<0.05) improved weight gain of Red Sokoto does. Animals fed dietary treatments containing 10% and 20% of GMMO leaf meal had significantly (P<0.05) higher weight gain (3.30kg and 3.38kg) than animals on 30% inclusion level. The feed cost/kg gain ranged from N 326.75 in 20% followed by N354.59, N 441.74 and N518.30 in 10%, 30% and 0%, respectively. The cost-benefit analysis showed that at 20% GMMO leaf meal inclusion, cost of feed/kg gain was reduced by 36.96% and gave more profit. The GMMO leaf meal inclusion did not have any adverse effect on Red Sokoto does. It can be concluded that mixed Gmelina and Moringa leaf meal can be included at 20% in diets of Red Sokoto does for improved dry matter intake, average daily weight gain and profitability.. Leaf meal, weight gain, Red Sokoto goats, Gmelina arborea and Moringa oleifera. the treatments. The feed intake varied from 421.50 to 455.95g/d in animals fed 30% and 20% respectively. Final weight of does was also not significant (P>0.05) but increased with GMMO leaf meal inclusion. Animals on 10% and 20% leaf meal inclusion had significantly higher (P<0.05) weight gain than the other treatment groups. Average daily weight gain (ADG) in this study showed no significant (P>0.05) difference across the treatments. ADG varied from 38.81 to 55.48 g/d. There was no significant (P>0.05) difference in feed conversion ratio. It varied from 8.73 to 13.18 in animals fed 20% and 30% leaf meal inclusion respectively.


Abstract : The Contractor has designed, fabricated, tested, and delivered both a breadboard- and a flight-model Positive Ion Ejection System (PIES) to the Air Force Geophysics. The flight-model system will be employed to eject positive charge from a rocket (BERT I) in order to simulate and investigate spacecraft charging. The PIES models each consist of an argon-ion source; an argon expellant tank; power, command, and telemetry electronics; and suitable packaging. The ion source emits an unneutralized argon-ion beam at selected voltages in the energy range from 0.5 to 4.5 keV, with selected ion-beam currents in the range of 0.02 to 20 mA. The flight-model PIES exhibits environmental-tolerance attributes suitable for rocket launch. Design considerations, final design configuration, and test data are presented. Keywords: Ion sources, Spacecraft charging, Rocket charging, Ion Beams, BERT I rockets.

The essential survey of the literature data, concerning the brisance of high explosives (HE) has been made in this paper. It is confirmed that the quantitative criteria of the theoretical estimate of the HE brisance proposed in the scientific literature are based on several assumptions, which are contradictory to the real course of the explosion phenomenon, and therefore they are erroneous. These criteria must not be applicated in the engineering practice. The reflection process of the detonation wave from the inertial rigid partition was used in order to derive the new formula describing the relative brisance of the HE. Moreover, the brisance of numerous commercial explosives and the military ones has been analysed, too. The results, presented in this paper, are confirmed by experimentally gained data.

The author argues that the protection of urban land should be combined with their effective utilization, which presupposes compliance with the environmental, town-planning and other requirements in the process of land use. The essence of the concept of "protection of land in the settlements" is revealed. The article provides a comparative analysis of the town-planning models zoning currently applied in the domestic practice. The author is convinced that many contradictions, arising when the town-planning zoning is been carried out, can be overcome by development of the guidance documents based on the practice of setting and application of the town planning regulations.

W Moses came down from Mt. Sinai, he did not bring "guidelines"—he brought the Ten Commandments. American Society of Plastic Surgeons (ASPS) members are looking for commandments—well-documented, substantiated proof of answers to the clinical questions that we all face as we perform reduction mammaplasty. Unfortunately this is lacking for the most part, as delineated by the blue ribbon panel assigned to collate the data on breast reduction. This ASPS Task Force recognizes these shortcomings, saying that these guidelines are generally acceptable approaches to meet the needs of most patients, but they are not rules or standards of care. Nevertheless, guidelines are examined by physicians, the media, and the public. They are quoted by lawyers and insurance companies. I do not think that many ASPS members will disagree with the statement that reduction reduces the symptoms of macromastia and improves the quality of life of macromastia patients. More than 100 studies come up in PubMed that document the many benefits of breast reduction, thus emphasizing the level I, grade A rating of this clinical question. We also know that drains do not prevent hematomas and that patients do not like them (level II, grade A). My own experience concurs that larger resection weights have a higher risk of complications and that many women benefit from reductions that are below the required weights of insurance companies (level II, grade B). However, what should we do with the grade Cs? Plastic surgeons rarely received Cs in college or medical school, and this makes us uncomfortable. However, we still have to decide tomorrow morning whether to give antibiotics to the reduction patient and whether to operate on that patient with the body mass index of 27. Let us look more closely at a grade C question. Should we give antibiotics to a breast reduction patient? A breast case is considered "clean," and there are definite disadvantages of antibiotics: cost, allergic reactions, suppression of normal flora, and potential selection of resistant organisms. Of the five antibiotic studies referenced by the panel, only two studied reduction patients exclusively. The study by Ahmadi et al.1 randomized 50 patients into three groups: no antibiotics, preoperative antibiotics only, and preoperative and postoperative antibiotics for 6 days. They found no difference in the infection rate among the three groups. Veiga-Filho et al.2 prospectively randomized 100 breast reductions: group 1 received intravenous cephalothin preoperatively and postoperatively and oral cephalexin for 6 days, and group 2 received no antibiotics. Infection rates were 2 percent and 14 percent, respectively (p = 0.03). Clearly, these studies are contradictory and do not tell us what to do. In the face of insufficient evidence, should we widen the scope and include evidence from studies of other breast surgery and not exclusively reduction mammaplasty? After all, "close" counts in horseshoes. In the New England Journal of Medicine, Platt et al.3 reported on 1218 patients undergoing "clean" hernia and breast surgery. The breast patients had breast biopsies, lumpectomy, mastectomy with or without axillary sampling, or breast reduction. They randomized two breast groups (n = 303 each) to receive a single preoperative dose of the antibiotic cefonicid or no antibiotics. The infection rate was 12.2 percent in placebo-treated patients and 6.6 percent in patients treated with antibiotics (p = 0.01). Bunn et al.4 in the Cochrane Database of Systematic Reviews collated eight studies in breast cancer surgery without reconstruction that evaluated preoperative antibiotics compared with placebo. Pooling of the results demonstrated that preoperative Discussion: ASPS Clinical Practice Guideline Summary on Reduction Mammaplasty


In an effort to address increasing water demands, a growing number of municipalities throughout the world are employing membrane technology to reclaim their wastewaters. Pilot studies, demonstration plants, and the use of membrane pretreatment have increased confidence in RO membrane technology for wastewater reclamation and fostered the design and construction of larger systems. In 2007, two of the world's largest wastewater reclamation plants using similar energy saving RO membrane technology will be commissioned on opposite sides of the Pacific. One plant, Orange County Water District's (OCWD) Groundwater Replenishment System (GWRS) located in Southern California, is expanding to 265,000 m3/d (70 MGD), while the other, Ulu Pandan located in Singapore, is producing 148,000 m3/d (39 MGD). OCWD's GWRS is being implemented in two phases over a three year period. Phase I, commissioned in April 2004, consists of a single 18,900 m3/d (5 MGD) system. Lessons learned during two years of Phase I operation are being implemented in the Phase II operation of an additional fourteen trains to be commissioned in mid 2007. Each train of the GWRS is equipped with energy saving membranes in three stages to achieve 85% recovery at a flux of 20.4 lmh (12 gfd). Water produced from the RO is further treated using UV with hydrogen peroxide and used for groundwater recharge and coastal injection to protect the existing freshwater basin from seawater intrusion. The stability of the energy saving RO membranes has been demonstrated at this site during extensive pilot testing. Ulu Pandan, commissioned in early 2007, is Singapore's fourth and largest wastewater reclamation facility. Each of Ulu Pandan's 13 RO trains uses an enhanced version of the same energy saving membranes installed at OCWD. The RO trains use a two stage design to achieve a recovery of 80% and flux of 11 gfd with the flexibility to increase to 20.4 lmh (12 gfd). RO permeate from Ulu Pandan is further treated with UV and delivered for indirect potable reuse and industrial water applications. This paper will discuss the evolution of the design of these large scale wastewater reclamation plants using energy saving RO membranes. Lessons learned from years of piloting, demonstration plants, and full scale plant experience at both OCWD and UP will be presented. RO performance data, including permeability, differential pressure, and salt passage will be presented as well as analysis of RO elements from each site after extended operating periods.


(57) Abstract: Demonstration of users based on biometric information in the past have been performed by correlating a single example of the biometric information to the template. It is difficult to prove the population ratio in this way. Furthermore due to damage or injury of the skin, there is a case where biometric information is not suitable for identification. Abrasion fingers affecting the influence sore throat and fingerprint information to the audio information are two examples of the common problems found when performing prove on the basis of the biometric information. Here it is disclosed a method of proving the user based on biometric input information. In order to customize the user biometric proven process in this way, the user can select the number of times to repeat the biometric information source and the information source.


Objectives. The aim of the study was to compare the values of myocardial blood flow (MBF) at stress, MBF at rest and coronary flow reserve (CFR) obtained by 13Nammonia stress-PET/CT in patients with various degrees of coronary stenosis and in healthy patients. And thus to estimate the possible contribution of the stress-PET/CT quantitative data to the detection of functionally significant coronary stenoses in patients with coronary artery disease (CAD). Materials andmethods. 63 patients (mean age 64±9 years) with known CAD underwent dynamic 13N-ammonia stress-PET/CT followed by calculation of MBF both at stress and at rest in absolute units and CFR. We compared quantitative values in two groups of patientswith coronary artery stenosis: 1)≥75% (n = 36) and 2)<75% (n = 27) confirmed by invasive coronary angiography and in group of healthy patients (n = 11). Results. MBF at stress was significantly lower in group with ≥75% diameter stenoses (median 1,44 [1,21; 1,85] mL/min per g) compared with group with <75% diameter stenoses (2,42 [1,75; 2,89] mL/min/g) and the normal group (2,54 [2,31; 2,86] mL/min/g), (p <0,001). There was no reliable difference in MBF at rest between the three groups (p = NS). CFR was significantly lower in the group of patients with severe ≥75% stenoses (1,85 [1,54; 2,31]) in comparison with patients group with stenoses of intermediate <75% severity (2,73 [2,19; 3,21]), and also in comparison with the normal group (3,12 [2,75; 3,23]), (p <0,001). Conclusion. The values of MBF at stress and CFR are significantly lower in patients with severe coronary arteries stenoses comparing with the group of patients with mild and moderate stenoses. The value of MBF at rest used independently has no diagnostic utility for detection of functional significance of coronary artery stenoses.

Nowadays security protocols are a key component in providing security services for fixed and mobile networks. These services include data confidentiality, radio link encryption, message integrity, mobile subscriber authentication, electronic payment, certified e-mail, contract signing and nonrepudiation. This paper is concerned with attacks against security protocols. Security protocols are introduced and the most common attacks against security protocols are discussed. The Wide-Mouthed Frog key-establishemnt protocol of Burrows, Abadi and Needham is presented. Attacks which exploit known weaknesses in the protocol are discussed and a corrected version of the protocol by Lowe is presented. Analysis of the Lowe modified Wide-Mouthed Frog protocol in this paper reveals a new parallel session attack. The reasons for this attack and how it can be mounted are discussed.


VAT is normally considered to have regressive distributional effects on income distribution. Many countries try to address distributional concerns with rate differentiation. Based on Swiss data we find that both the existing VAT as well as a revenue-neutral flat rate have no significant redistributive effects on the Gini coefficient. Further, we show that differentiated VAT rates only have weak intended distributional effects and that a different VAT structure can also not make VAT progressive regarding income. Based on our results, we conclude that introducing a flat rate should be considered.

We describe the isolation of six tetranucleotide microsatellites from the Cape sugarbird ( Promerops cafer ) using an enrichment protocol. All loci were highly variable with number of alleles ranging from nine to 26 and values of observed heterozygosity ranging from 0.534 to 0.931. All loci were in Hardy–Weinberg equilibrium with the exception of Pro66 and Pro86. Further analysis of Pro86 indicated it was Z-linked. All loci amplified and were variable in the congeneric Gurneys sugarbird ( Promerops gurneyi ). These loci will be used in mating system and phylogeographic studies of Cape sugarbirds in South Africa.


Six mutants of Rhizobium leguminosarum 3855 lacking uptake hydrogenase activity (Hup− phenotype) as a result of Tn5-mob mutagenesis of the hup-containing plasmid pRL6JI were tested for symbiotic performance on Pisum sativum L. and Vicia benghalensis L. Three pea cultivars and one vetch line, which induce four different levels of Hup activity in strain 3855, were grown to flowering under microbiologically controlled conditions in the absence of combined N. Direct Kjeldahl N measurements showed that in every case at least one Hup− mutant fixed as much N2 as the isogenic Hup+ strain. Measures of C2H2 reduction, H2 evolution, 3H2 incorporation, and plant dry weight were consistent with the interpretation that the oxidation of H2 produced by the nitrogenase enzyme complex was not necessarily associated with increased N2 fixation in these symbiotic associations. Tests with a smaller subset of the Hup− strains under four different root environments ranging from pH 5.0 to 8.2 likewise showed no significant advantage for the isogenic Hup+ strain. It was concluded that the improvements in symbiotic N2 fixation produced by pRL6JI are associated with some trait other than the Hup+ phenotype.


The utility model relates to a release type damping space bar used for keeping the space between power transmission line bundles. The release type damping space bar is composed of a clamping head body, a clamping head cover plate and a bracket, wherein the clamping head body is fixedly connected with the bracket and the clamping head body is rotatablely connected with the clamping head cover plate. The clamping head body is provided with a clamping head damping shim, and the clamping head cover board is also provided with the clamping head damping shim. The clamping head body is provided with a detachable pin shaft used for tightly fixing the clamping head cover plate, the clamping head body and the clamping head cover plate are respectively provided with mounting holes and the clamping head mounting hole is provided with releasing holes. Since the clamping head body of the utility model is provided with the releasing holes to form a cross section which can be damaged, the utility model can ensure normal use, the cross section which can be damaged in the clamping head body can crack when a clamping head of the utility model collides a catenary baffle plate to a definite impact force during the accident of the break of power transmission lines, the clamping head can fall automatically, conducting wires are released out and thus the damage of wire breaking tension to a power transmission iron tower is avoided.


The development of the environment of a company has a direct influence on its performance and its success. For this reason a company should not only analyze its internal performance, but also the external performance of the business environment and the su


It is shown in this paper that deviations of galaxy cluster lenses from spherical symmetry can render mass estimates for galaxy clusters based on the formation of large arcs systematically to high. Numerical models show that the mass needed for producing large arcs in clusters can be notably smaller than expected from simple spherically symmetric lens models. The reason is that the enhanced tidal effect in asymmetric and substructured lenses can compensate for part of the convergence necessary for strong lensing effects. An analytic argument is given to explain why deviations from radial symmetry will in general decrease the required lens mass. Mass estimates assuming radially symmetric lenses are on average too high by a factor of $\simeq1.6$, and with a probability of $\simeq20\%$ by a factor of $\simeq2$.

SUMMARY A 23‐year‐old man presented with an atrophic lesion on his left anterior shoulder that had been present for at least 10 years. A previous biopsy had suggested a fibrohistiocytic origin; however, clinically it resembled morphoea or atrophoderma, and the lesion was observed. Fifteen months later, the lesion was noted to have grown slightly. A repeat biopsy showed dermatofibrosarcoma protuberans, with a storiform spindle cell proliferation with positive CD34 staining. The lesion was excised with a 3‐cm margin. Awareness of this rare presentation may assist in earlier diagnosis.


In this paper, we consider the optimal dividend payment strategy for an insurance company that has two collaborating business lines. The surpluses of the business lines are modeled by diffusion processes. The collaboration between the two business lines permits that money can be transferred from one line to another with or without proportional transaction costs, while money must be transferred from one line to another to help both business lines keep running before simultaneous ruin of the two lines eventually occurs.


Using electropherograms (zymograms) of the phenoloxidase laccase and characteristics of mycelial growth and fruit body production, a distinct morphological and biochemical differentiation of two geographically isolated (allopatric) populations of the wood-rotting basidiomycete Pleurotus ostreatus became evident. No limitation in their outbreeding ability was observed, however. A specific secretory mechanism for an extracellular laccase, genetically different in the two geographical races, could be detected. An approximately 1: 1 segregation of this laccase band in the F1 generation indicates that specific secretion of this enzyme is controlled by one gene only, Different degrees of genetic variation as shown by differences in the respective laccase spectra were found in the two geographical races. Only one enzyme band out of nine multiple laccases was found to be specific for fruit bodies. The value of zymograms for chemotaxonomic purposes, for the understanding of microevolution and for determination of genetic variation in fungi is critically discussed.


In this paper, the quantitative estimates of the effect of large-scale circulations on the sea surface temperature (SST)-tropical convection relationship and the effect of SST on the large-scale circulation-convection relationship over the tropical Indian and Pacific Oceans are presented. Although convection tends to maximize at warm SSTs, increased deep convection is also determined by the divergence (DIV) associated with large-scale circulation. An analysis of the relationship between SST and deep convection shows that under subsidence and clear conditions, there is a decrease in convection or increase in Outgoing Longwave Radiation (OLR) at a maximum rate of 3.4 Wm -2 °C -1 . In the SST range of 25°C to 29.5°C, a large increase in deep convection (decrease in OLR) occurs in the tropical Indian and Pacific Oceans. The OLR reduction is found to be a strong function of the large-scale circulation in the Indian and western Pacific Oceans. Under a weak large-scale circulation, the rate of OLR reduction is about    -3.5 Wm -2 °C -1 to -8.1 Wm -2 °C -1 . Under the influence of strong rising motions, the rate can increase to about -12.5 Wm -2 °C -1 for the same SST range. The overall relationship between large-scale circulation and deep convection is nearly linear. A maximum rate of OLR reduction with respect to DIV is -6.1 Wm -2 (10 -6 s -1 ) in the western Pacific Ocean. It is also found that the DIV-OLR relationship is less dependent on SST. For example, the rate of OLR reduction over the western Pacific Ocean for 26°C < SST £ 27°C is -4.2 Wm -2 (10 -6 s -1 ), while that for 28°C < SST £ 29°C is  -5.1 Wm -2 (10 -6 s -1 ). These results are expected to have a great importance for climate feedback mechanisms associated with clouds and SST and for climate predictability.


Amplification of AML1 has been reported in pediatric acute lymphoblastic leukemia (ALL): it occurs mainly older in older children (5 to 14 years-old) as well as in CD10 positive B ALL and a few cases of acute myeloid leukemia. The presence of double minute chromosomes (DMs) may be one of the mechanisms for oncogene up-regulation. It is a rather rare event in hematological malignancies and is generally associated with a poor prognosis. Until now, DMs have been described mainly in AML and involve mainly amplification of c-MYC and MLL. We report here the case of a 14-year-old boy with CD10 negative biphenotypic acute leukemia (B + M). Bone marrow cytogenetic analysis revealed a (47, XY) clone with one normal chromosome 21 and two small markers consisting of chromosome 21 material as the sole abnormality. The two markers were consistent with different forms: small acrocentric, small metacentric and appear to be a mixture of those forms until resembling double minute. Fluorescence in situ hybridization (FISH) was performed using the TEL-AML1 ES probe. Metaphase FISH showed one normal signal, one tandem signal and a third signal with an apparent variable structure. In interphase nuclei, the hybridization showed from 2 to >6 signals without neither tandem duplication nor clustered signals in an area within the interphase nuclei as previously reported in B-ALL. In our case, we hypothesize that the different forms of the "derivative/deleted" chromosome 21 lead to form DMs containing the AML1 gene. The mechanism seems to be multistep chromosomal rearrangements with formation of an iso-chromosome 21 and deletion of part of chromosome 21. To our knowledge, it is the first case of biphenotypic AL reported with AML1 amplification and a probable double minute mechanism.


The article considers the existing system of state and municipal financing of physical culture and sports in the Russian Federation as one of the important branches of the social sphere. Financing of physical culture and sports is carried out through the budget system of the Russian Federation, with the main share of funding coming from regional and local budgets. In recent years, expenditures on financing physical culture and sports have been growing faster than the total expenditures of the consolidated budget of the Russian Federation. In Russia there is a wide network of Federal, regional and municipal organizations that receive various subsidies from the budget system of the Russian Federation. These include budgetary and Autonomous institutions, unitary enterprises. The article analyzes the financial support of budgetary institutions subordinated to the Russian Federation Ministry of sports. These institutions carry out the state task to provide services in the field of physical culture and sports. It is revealed that the main share of all subsidies allocated for the financing of physical culture and sports are subsidies for the financial support of the state task. They are calculated by sports on the basis of normative costs for the provision of state (municipal) services in the field of physical culture and sports. They are different for organizations of Federal, regional and local subordination. The analysis showed that half of the expenditure falls on the sport of higher achievements, which is understandable, given the importance and necessity of state support for the development of this area. Keywords—subjects of financing; sources of financing; budgets of the budget system of the Russian Federation; incomes of institutions; efficiency of expenses.


Recently, the application of navigation system to electric devices such as cars, airplanes, and cellphones has become common. This common usage increases the demand for GPS, and therefore, GPS accuracy has become important. However, applying an external correction device or using a high-accuracy GPS receiver is very expensive; thus, practical applications of robotic systems using this technology are limited. Therefore, in this paper, we propose a method of using multiple low-cost GPS receivers in position estimation to enhance accuracy and decrease system buildup cost. The position estimation is based on the following steps: 1) sensor modeling of each GPS receiver, and 2) position estimation using extended Kalman filter based on the model of each sensor. The result of this study showed enhanced accuracy of the position estimation and the correlation between the number of GPS receivers used and accuracy of the position estimation. The position-estimation accuracy can be enhanced with low system buildup cost, and therefore, the proposed method can contribute to the field of robot control in outdoor environment.


Abstract Archaeological data from the Jequetepeque Valley suggest that Late Moche warfare and religious sacrifice were embedded in a particular cosmological and gendered construction of the world. As a consequence, the pragmatic motives implicated in violent conflict were mediated by structures of practice specific to the Moche. An analysis of the archaeological record points to the existence of this cultural schema, the identification of which better explains the ascendancy of the famed priestess cult based at San José de Moro and the general decentralization of power in the Jequetepeque region. The evidence indicates that political relations in the valley were informed by a religious ideology that structured feasting, warfare, and sacrifice as specifically gendered but complementary domains. The spatial delimitation and sequential unfolding of ritual events were likely deemed essential for both socio-cosmic renewal and legitimate political advancement. This gendering of political and religious practices is reflected archaeologically in the division of centered and rural space and in the differential distribution of architectural forms, parochial feasting arenas, and iconographically charged artifacts. Ultimately, the archaeological record demonstrates that the political machinations of rural communities amplified this gendered sacrificial system within the context of the environmental upheavals of the Late Moche Period.


Evaluation of mechanical properties is a powerful tool for investigating and assessing the performance of service exposed materials. The trends recently observed in a service exposed (32 years) plain carbon steels used as a reactor vessel material in a petrochemical industry have been highlighted in this paper. Health assessment of both base and welded joint was made using destructive accelerated stress rupture and tensile tests at different temperatures, and some nondestructive tests. From the stress rupture tests it could be concluded that a life of more than 10 years at the hoop stress level of the material can be obtained, provided no localised damages in the form of cracks or dents have been developed. It is recommended that a health check may be carried out after 5 years of service exposure at 758 K.


It provides the pilot allocation method for a plurality of OFDM (Orthogonal Frequency Division Multiplexing) symbol and a number of a multiple antenna system for assigning a pilot sub-carrier over the sub-carriers. The method is characterized in that assigned to each of the pilot sub-carriers for a plurality of antennas equivalent to the number for each OFDM symbol. In addition, each of the pilot subcarrier is allocated to a time-domain OFDM symbol to each other to switch on the two adjacent, made a two by two pair. It may be evenly allocated over the transmit power required for the antenna in each time point, it is possible to reduce the pilot overhead. Pilot, Subcarrier, Allocation

There exists very general discriminations and mismatches for the old workers and poor workers. This paper built a model to explain the reason of that phenomenon based on asymmetry information. A skilled worker may be mismatched with unimportant jobs because of the social bias towards old workers and poor workers, in that situation, the expense workers spend to become skilled will not be covered, which will be a big disincentive for workers to be skilled. The disincentive will lead to less skilled workers, so the working performance of certain kinds of workers in the whole society will be worse, which will confirm the discrimination. In that process, the expense to be skilled is a key factor. And we also try to use that model to explain some phenomena, such as East Asian miracle and class solidification.


University and school preparation of new teachers should include work on the ethical and policy quandries of professional work. As it is, teacher education institutions too rarely tackle questions of protocol, ethics, policy, principles, and procedures. Professors may discuss matters of protocol, especially ethical conflicts arising from school and university practices and routines. But they rarely give in-depth treatment to ethics and policy in the teaching life. Moreover, treatment of these matters is often sparse in ethical theory or in reasoned analyses of protocol and policies. This leaves the new teacher without initiation into centrally important elements of teaching. The appropriate treatment of protocol, ethical, and policy matters in education programs warrants a separate course of instruction. Here, students would be encouraged to improve their ethical reasoning and to learn ethical theory. They would learn various ways to assess protocol and policy problems likely to arise in classrooms and sc...

Now that the "season" is fast approaching for field-work, a few remarks concerning the geology of the above locality will doubtless be acceptable to many of our readers. Such of them who may have broken ground on it will remember with pleasure its beautiful scenery and the peculiar charms which attract the naturalist to it. That it is interesting in more respects than a merely geological one, is shown by the botanists who wander there in search of rare and beautiful plants, and the antiquarian who finds in its old keep and other more ancient relics subjects for thought. Above all "Moultrassie Hall" and "Peveril Castle" hold an honoured place in our literature enshrined by the genius of Scott. The flora of the locality is particularly interesting, especially that of the lower class. Maidenhair, spleenwort, and rue-leaved spleenwort grow upon almost every wall; and the cystopteris in several species is also common, whilst the adder's-tongue and the little moonwort are exceedingly plentiful in the richer pastures. The number of mosses is exceedingly great. The beautiful Bryum dendroides and others abound in the moister spots of the Cave Dale. In fact, the botanical character of the vegetation hereabout is so peculiar to the three formations which are found as to form a geological map to the underlying rocks, coloured by nature herself! The limestone clothed with its short and beautiful carpet of green; the black shales of the Yoredale rocks covered by their stunted and brown vegetation; and the millstone-grit in the glowing summer-time quite purple with the flowers of the heather.


Electrochemical studies of [CoII2L(MeCN)4][ClO4]4 1, the first structurally characterised dicobalt complex to be bridged by pyridazine units, reveal two one-electron reductions as well as two one-electron oxidations at high potentials; one-electron reduction generates a mixed valent CoICoII species which exhibits an intervalence charge transfer band at 965 nm.


Barrett, R.L. Poranthera moorokatta (Phyllanthaceae), a rare new species from Perth, Western Australia. Nuytsia 22(6): 399–407 (2012). Poranthera moorokatta R.L.Barrett is described as a new species recently discovered in Banksia woodland in Kings Park, in the heart of the Perth metropolitan area. Poranthera moorokatta is morphologically allied to P. triandra J.M.Black, a woodland species distributed from Lake King in Western Australia to the Grampians in Victoria, and perhaps also to P. dissecta Halford & R.J.F.Hend., a species from granite outcrops in south-east Western Australia.


at 5%). Microbial reductions fell within 2-3 log cycles. When compared to water-washings, ozonated water and solutions of AMUKINA and H 2 O 2 allowed higher microbial reductions.


Objective To provide the anatomical evidence for extended transsphenoidal approach into the medial compartment of cavernous sinus.Methods Fifty adult cadaveric head specimens were dissected in detail under an operating microscope for observing and measuring the lateral wall of sphenoid sinus,sella turcica,cavernous sinus and related structures.The transsphenoidal approach was extended by stripping the ventral bone of cavemous sinus,cutting the median wall of cavernous sinus to exposure the median compartment.Results In 58% cases,the internal carotid artery(ICA)was prominent beyond the median wall of sphenoid sinus,and in 3%,the prominence was of canal form.The medial wall of cavernous sinus had two separate components.In its upper part,the medial wall of the cavernous sinus was formed by the dural layer of the pituitary gland without bony support;in its lower part,the medial wall of cavernous sinus was formed by the periosteal dura of the sella turcica and supported by the bone of the lateral wall of the sphenoid sinus.The mean distance between the two medial walls of the cavernous sinus was(14.8±2.7)mm.The medial compartment of cavernous sinus was located between the ICA(C4 segment)and pituitary gland,and was filled with venous plexus,with the largest width of 7 mm.The veins were often twisted and occluded because of ICA prominence.No cranial nerves traversed the medial compartment.The ICA was the first major structure encountered in the exploration of the cavernous sinus through a transsphenoidal approach.Conclusion The data prove the safe and feasibility of the clinical application of the extended transsphenoidal approach into the medial compartment of cavernous sinus.


We derive physically meaningful boundary conditions at outflow boundaries which render the artificial boundary transparent in the sense that no unphysical dissipation is introduced into the system. The resulting class of dynamic ABCs is studied in the halfspace prototype case concerning local-in-time strong wellposedness. ∗Speaker sciencesconf.org:equadiff2015:72448


Titanium dioxide thin films were grew on GaAs,Si,and glass substrates by low pressure chemical vapor deposition(LPCVD).The three films were characterized by high resolution X-ray diffraction(HRXRD),field emission scanning electron microscopy(FESEM) and energy dispersive X-ray spectroscopy(EDS).The results showed that the substrate type had obvious effect on crystalline structures and surface morphologies of TiO2 films.Photocatalysis test results showed the TiO2 films deposited on GaAs and Si substrate had enhanced photocatalytic activities for the degradation of methyl orange under visible light irradiation compared with the TiO2 films deposited on glass substrates.The influences of substrate type on the crystal morphology,microstructure,photocatalysis property of TiO2 films were discussed in detail.


In MANET environments, resource sharing among nodes will be one of the problems to be solved. To solve the problems, the desynchronization algorithm, called DESYNC-TDMA, has been proposed as a variation of firefly-inspired algorithm. However, it has still problems of slow convergence and resource wastes as the number of nodes increases. In this paper, we propose an enhanced DESYNC-TDMA not only to reduce the convergence time, but also to enhance the packet delivery efficiency. The effectiveness of the proposed method has been shown by implementing the method using OPNET simulator.
