At signalized intersections, right of way allocation must not only consider conflicting vehicle movements, but also account for conflicts of vehicle with pedestrians and bicycles. Presently, the U.S. Highway Capacity Manual considers the impact of pedestrians on right and unopposed left turn movements capacity only, while their effect on permissive left turns is ignored. Bicycles on the other hand are assumed to act as motor vehicle-equivalents in some cases (e.g. on through lanes) and as pedestrians in others (e.g. when conflicting with a right-turn movement). These ad-hoc approaches to pedestrian and bicycle analyses reflect a lack of nation-wide research that can provide the necessary empirical foundation for model development and validation. This paper presents the results of a nation-wide U.S. study on the effect of pedestrians and bicycles on vehicle movement operations. This paper describes the field studies and recommends analytical and simulation models for capturing pedestrians and bicycles at signalized intersections.


Abstract Indexed powder diffraction patterns and related crystallographic data are reported for tetracycline-urea tetrahydrate and tetracycline hexahydrate, neither of which is represented in the X-ray Powder Diffraction File. Objective evaluation of the data indicates high precision of d-spacings and unit-cell parameters, intensities that are acceptably reproducible, sensitivity for low intensity reflections, good resolution of closely spaced reflections, and close correspondence with calculated patterns.


Coccinelle is a program-transformation system for C code. It has been under development since 2005 and has been extensively used on the Linux kernel. The design of Coccinelle was inspired in part by the author's previous experience in using Stratego/XT, developed by Eelco Visser. This paper reflects on some of Coccinelle's design choices and their relation to Eelco Visser's work. 2012 ACM Subject Classification Software and its engineering → Software evolution


Using the Stackelberg differential games(SDG) theory, we quantitatively study a problem of optimal intertemporal investment and tax rate design. Under some appropriate assumptions, the open-loop Stackelberg equilibrium solutions are obtained. Equilibrium solutions show that: 1. The optimal strategies derived from differential game and unilateral optimal control approaches are different; 2. It is not always the best strategy for the government to use a constant tax rate over the whole time period; 3. The admissible size of tax rate adjustment may have great effect on the government's optimal strategy; 4. SDG approach has no significant effect on the firm's optimal investment strategy.


Predicting the performance of the ΕΔΕΔ analog to digital converters (ADCs) is a computationally expensive task that can take several days for estimating the performance. In this paper, we propose a new circuit/behavioral simulation framework for accurately estimating the performance of CT-ΕΔ-ADCs. Our framework is based on newly developed simulation-directed macro-models and associated mapping techniques for accurately modeling and simulating the CT-ΕΔ-ADCs in the presence of the various non-idealities. We validate our circuit/behavioral framework by the simulation of a 2nd order low pass and a 4th order band pass ADCs. Our newly developed framework predicts the performance degradation within an error less than 4% while achieving three orders of magnitude simulation speedup.


We define an oscillating sequence, an important example of which is generated by the Möbius function in number theory. We also define a minimally mean attractable (MMA) flow and a minimally mean-L-stable (MMLS) flow. One of the main results is that any oscillating sequence is linearly disjoint from all MMA and MMLS flows. In particular, this confirms Sarnak's conjecture for all MMA and MMLS flows. We provide several examples of flows that are MMA and MMLS. These examples include flows defined by all $p$ -adic polynomials of integral coefficients, all $p$ -adic rational maps with good reduction, all automorphisms of the $2$ -torus with zero topological entropy, all diagonalizable affine maps of the $2$ -torus with zero topological entropy, all Feigenbaum maps, and all orientation-preserving circle homeomorphisms.

GENERAL COMMENTS This is an interesting study of the sequelae of mild (m) TBI in a Taiwan population. The study shows data from a relatively large number of subjects, no doubt because of the extensive clinical data registry system in that country. While the data appear quite solid and the analysis is sound, there are some additional consideration that should be explored in the Discussion. In this article, the authors measured depression, anxiety, and sleep in patients who suffered mild traumatic brain injury (mTBI) at baseline (250 patients) and after 6 weeks (100 patients) using four subjective but validated scales for anxiety (Beck Anxiety Inventory), depression (Beck Depression Inventory), daytime sleepiness (Epsworth Sleepiness Scale), and sleep quality (Pittsburgh Sleep Quality Index). These results were compared with data from 100 healthy individuals. mTBI patients were found initially to suffer significantly worse sleep quality, depression, and anxiety, but sleep quality was not significantly different from the control group after six weeks, while depression and anxiety scores were still worse. Daytime sleepiness was not altered either at baseline or six weeks. The authors conclude that recovery of sleep disturbance after mTBI occurs more rapidly than depression or anxiety. This is an interesting study of the sequelae of mild (m) TBI in a Taiwan population. The study shows data from a relatively large number of subjects, no doubt because of the extensive clinical data registry system in that country. It is of interest that more women than men participated in the study, since in western countries, particularly the USA, there are significantly more men than women who suffer mTBI. The findings of the study are novel and have


In order to solve the problems such as soil and water loss, eco-environmental degradation, frequentflooding and drought disasters in the Poyang Lake Basin before the 1970's, the approach of integrated watershed management has been adopted and applied, and "Mountain-River-Lake Integrated Development and Management Program" has be implemented. The program combined greening mountains and harnessing rivers with economic development aiming to pursuing the balance of social-economic development, environmental protection and ecological reconstruction. With the unremitting efforts in the past 20 years, a "green Jiangxi" has been constructed , and the capacity of regional sustainable development has been enhanced. After the entrance of the new century, the development strategy of "gold mountains and silver mountains are needed, but clear waters and green mountains are much more desirable" was put forward and the social-economic development in the Poyang Lake Basin was speeded up with the precondition of eco-environmental protection.


A materials budget was estimated for the Magela Creek system during the 1982-83 wet season. This tropical system in northern Australia consists largely of a well-defined creek (Magela Creek contributes approximately 50% of the total inflow to the floodplain) flowing into an extensive wetlands area and then into the East Alligator River. Intensive sampling of creek water, rainfall and water flowing from the system provided the data base for the budget calculations. The annual transport of both dissolved and particulate matter by Magela Creek (area 600 km2) is very low, even when compared with other low-relief tropical systems. The annual load transported during 1982-83 was 1260 t (21 kg ha-') of dissolved salts and 2330 t (39 kg ha-') of particulate matter. Rainfall appeared to contribute all the sodium, potassium and chloride, and part of the calcium (c. 30%) and magnesium (25%) transported during the 1982-83 wet season by Magela Creek. Most of the manganese (c. 60%) (and probably iron) was contributed from weathering processes occurring in the catchment. Only small amounts of the trace metals copper, lead, zinc and uranium were transported by the creek. During the 1982-83 wet season, more trace metals were contributed in rainfall than transported from the catchment by the creek. However, this is probably atypical and resulted from dust particles that had entered the atmosphere in greater numbers due to the extended dry season. The vast bulk of the nutrients (total P 93070, NO; -N 86070, NH~ -N 98%) added to the catchment by rainfall was removed by the catchment, probably via uptake by the vegetation. Consequently, the creek transported only very small amounts of nutrients to the floodplain. An input-output budget for the Magela floodplain was calculated. The uncertainty in the net amounts deposited or released from the floodplain was estimated using a new quantitative method developed for this purpose. The uncertainties in the net values estimated were high, ranging from around 30% for bicarbonate to 500% for uranium. These data suggest that the Magela floodplain is a net source of the major ions (sodium, potassium, calcium, magnesium, chloride, sulfate and bicarbonate) and also of iron, and a net sink for suspended solids, nutrients (total phosphorus, nitrate and ammonia) and manganese. The floodplain also appears to be a net sink for the trace metals copper, lead, zinc and uranium.


The purpose of the techno-pedagogical models that have been developed is to apply the most accurate information and communication technologies (ICT) use to the instructional design that is planned to be executed. Among the different models revised to develop the current research, the flipped learning model reveals application possibilities in the public high schools. In general, the flipped learning model proposes that the direct instruction is replaced by learning materials, which are delivered outside the class while typical homework activities are implemented in class time. On this basis, a flipped classroom experience was carried out in the "Reading comprehension in English as a foreign language" class in the fifth semester of a public high school in the city of Xalapa, Veracruz (Mexico). Digital resources and multimedia activities were developed and hosted in a Moodle platform. A quantitative-based approach was used along with a quasi-experimental design with control and experimental groups. Standardized tests for pre and post assessment of written text comprehension were also used. The results show statistically important evidences that allow to make some promising considerations.


The groups of tropical cyclones are considered. A group is understood as a totality of cyclones, more-less coinciding with each other in time. In each group, the main cyclone is the most intense. The nature of the intensity and dynamics distributions of the group cyclones relative to the main cyclone is determined.


Our recently developed potential characterization method for studying the zeolite acidity is reviewed. In this method, ammonia TPD is a principle technique and first the principle of the method was explained. In order to overcome the drawback existed in the usual TPD, IRMS-TPD method was developed, in which IR and MS were measured simultaneously to monitor the thermal behavior of ammonia molecules on the surface and in the gas phase. The developed method made it possible not only to measure the Bronsted and Lewis acid sites individually but also to clarify the distribution of Bronsted acid sites. In addition, DFT calculations were carried out to confirm the obtained information of the Bronsted acidity. Based on these studies, a new technique was developed by combining the IRMS-TPD experiment and DFT calculation to precisely characterize the zeolite acidity. Using the developed method, the modified Y zeolites active for the cracking of hydrocarbons were studied.


Based on the sources and characteristics of petrochemical wastewater, various technological methods for petrochemical wastewater treatment are summarized, and energy consumption analysis is conducted on the treatment process, pointing out the problems of non-environmental protection, high energy consumption, low resource conversion rate, and low treatment efficiency in the process of petrochemical wastewater treatment. In response to the above energy consumption issues, energy-saving and consumption reduction development strategies for petrochemical wastewater treatment plants are summarized from two aspects: high-energy-consuming equipment and energy-saving optimization control. The energy-saving transformation methods of water pumps, aeration blowers, and accurate dosing processes are summarized, and the application schemes of model simulation control technology and intelligent control technology in accurate aeration control are analyzed for their feasibility to reduce energy consumption while improving pollutant removal efficiency in wastewater. Finally, a summary and outlook are provided, and the development of simple and efficient intelligent control algorithms is proposed to further promote the development of petrochemical wastewater treatment plants.


The integrated adhesive wear model tokes into account both the transient wear and the steady-state wear in wear testing. The transient wear volume is described by an exponential equation while the steady-state wear by a revised Archard's equation. In this study, the integrated wear model was used to analyze experimental wear data obtained previously for an A6061-T6 alloy and MMC-D, an aluminium alloy matrix composite containing 20% spherical alumina particles. Two loads of 7.5 kgf and 10.0 kgf, and a speed of 4.58ms−1 were used in conducting the experiments. Both the standard wear coefficient and the net steady-state wear coefficient values for both types of materials were determined. On the average, the average standard steady-state wear coefficient, as compared with the net steady-state wear coefficient, was about 52% higher for MMC-D and 246% higher for A6061-T6. A higher load was found to have the effect of increasing the wear coefficient values. Scheduled for Presentation at the 58th Annual Meeting in New York City April 28–May 1, 2003

Anodic oxidation products in 5N KOH of both planar and porous iron electrodes were investigated with SEM techniques. On the first discharge level well-defined crystallites of Fe(OH)/sub 2/ are formed, while on continued discharge the products become sludge formed, probably consisting of hydrated FeOOH. The morphologies support the dissolution--precipitation mechanism during the first discharge step. The second anodic level proceeds probably via migration of ions and electrons in the solid phase. The crystallite size increases with temperature which depends on the fact that the relative supersaturation decreases. (7 figures, 1 table)


ON THE CLASS NUMBER OF THE FIELD 0(e2irIP*) AND THE SECOND CASE OF FERMAT'S LAST THEOREM By H. S. VANDIVZR DBPARTMINT OF MATIHMATICS, CORNELL UNIVERSITY Communicated by L. E. Dickson, March 31, 1920 In the July 1919 number of the Bulletin of the American Mathematical Society, page 458, I gave an expression for the residue of the first factor of the class number of the field defined by e-iT/P, p being prime, with respect to the modulus pa, in terms of Bernoulli numbers. In the present paper an analogous expression for the residue of the first factor of the class number of Q(e2i/P1) modulo p, will be obtained and the result used to show that certain results due to Bernstein1 on Fermat's last theorem do not have the generality stated by him. In view of the criticisms on Kunmmer's 1857 memoir on the last theorem which I have given elsewhere2 it is then pointed out that up to the present time no rigorous proof of the theorem for the exponents 59 and 67 has been given. Westlund3 reduced the first factor of the class number of Q(e2iw/IP), if n>i,to theform ll.p(Os)

Chitosan is a natural polysaccharide with non-toxic,biodegradable,and biocompatible properties,it has been widely used in many fields.However,its applications have only been shown in acidic medium because of its poor solubility under other pH value.To enhance its application,the solubility and the physicochemical and biological properties,chemical modifications of chitosan were made.Quaternization is a popular means of modifying chitosan resulting in a water-soluble chitosan derivative with a wide pH value range.This is due to a permanent positive charge on the polymer backbone.Applications of quaternary ammonium salt of chitosan and its derivatives are reviewed.


Smart grid has emerged as the next-generation electricity grid with power flow optimization and high power quality. Smart grid technologies have attracted the attention of industry and academia in the last few years. However, the tradeoff between security and efficiency remains a challenge in the practical deployment of the smart grid. Most recently, Li et al. proposed a lightweight message authentication scheme with user anonymity and claimed that their scheme is provably secure. But we found that their scheme fails to achieve mutual authentication and mitigate some typical attacks (e.g., impersonation attack, denial of service attack) in the smart grid environment. To address these drawbacks, we present a new message authentication scheme with reasonable efficiency. Security and performance analysis results show that the proposed scheme can satisfy the security and lightweight requirements of practical implementations and deployments of the smart grid.


The number of Americans receiving institutional psychiatric care has decreased by the hundreds of thousands since deinstitutionalization in the 1960s. However, according to the President's New Freedom Commission, the community mental health system's inability to care for those released has led to rising incarceration of the mentally ill (Human Rights Watch, 2003). This has increased psychologists' involvement with courts, jails, and prisons, which have surpassed the Veterans Administration system as the largest employers of psychologists. These changes have led psychologists into increased contact with the legal system that is, into forensic psychology practice.


The invention discloses an under-sea modularized transformer station which comprises a plurality of modularized DC/AC converters which convert DC transmitted along a DC electric energy transmission line into AC electric energy and supply the AC electric energy to a plurality of under-sea loads. The input ends of the modularized DC/AC converters are serially connected with the DC transmission line, and the output ends are parallelly connected with an AC distribution network. At least one modularized DC/AC converter among the modularized DC/AC converters is configured to selectively disconnect electric and mechanical connection with the DC transmission line and AC distribution network, so that the AC distribution network continuously provides AC electric energy to at least one under-sea load when the at least one modularized DC/AC converter is under maintenance. The invention further provides a DC electric energy transmission system and method.

The relationship and interaction between international human rights law and cultural diversity is a current topic, as is shown by the recent debates in The Netherlands on, for instance, the proposed ban on wearing facial coverage, or burqas, and the proposed ban on ritual slaughter without anaesthesia. Human rights and cultural diversity further concern issues such as whether a person should be permitted to speak Frysian instead of Dutch in court, whether double nationality implies an undesirable loyalty problem, or whether Sinterklaas should be acknowledged as intangible Dutch cultural heritage or be dismissed as a racist celebration. One can also think of issues such as to what extent states should facilitate and fund education in minority languages, to what extent non-formal marriage rituals should be recognized, how land rights for indigenous communities can be reconciled with the economic benefit of mining and logging operations, and the wearing of religious symbols, such as headscarves, turbans and kippas in public schools. All of these issues are crucial to many individuals and communities, because they are expressions of their culture and consequently their identity. And to the extent that those cultural identity elements are associated with human dignity, there is a link with human rights. This lecture explores the scope of international human rights law for promoting and protecting cultural diversity, both at a global and at a regional level. It looks at the human rights standard-setting by states, at the human rights norms themselves and at the monitoring of human rights by international supervisory bodies.


Giant magneto‐impedance effects in different measuring geometries (longitudinal and transverse) of amorphous Co70.4Fe4.6Si15B10 ribbons under different field annealing have been studied at various frequencies (0.1 Hz–2 MHz). For suitably annealed samples, rich peak features have been observed in longitudinal MI measurements. For transverse MI measurements, a large effect magnitude has also been found. These results are discussed in terms of the effects of the magnetic annealing and measurement geometries on the effective permeability.


This paper examines how the distribution of household wealth in Canada varies with age over the life cycle. The wealth distribution is characterized in terms of decile means and decile shares for each of six age groups, and comparisons between age-specific distributions are based on first- and second-order stochastic dominance criteria. It is found that (i) mean wealth levels and wealth distributions increase significantly with age in concave quadratic fashion until near retirement and then decline, and (ii) wealth inequality declines in convex function with age, at first steeply and then not significantly. This joint pattern in mean and inequality of wealth holdings across age groups presents a challenge for basic theories to explain.


rn Selenium was determined by neutron activation in 22 samples of snow and rain collected during the 1964-1965 winter and in seven air samples collected during the following spring in Cambridge, Mass. Sulfate was determined gravimetrically or turbidimetrically in most of the samples. In these samples and in well water and Cambridge tap water analyzed for comparison, the selenium concentration averaged 0.2 Mg. per liter of water or per 200 cu. meters of air, and the average value of the weight ratio Se/S = 1 X loT4. Approximately the same ratio is commonly found in igneous and sedimentary rocks, sulfide ores, and fossil fuels, but the sea water ratio is one thousandth as large. This information implies mainly a terrestrial, including pollution, source for selenium as well as sulfur in the atmosphere of the city of Cambridge.

Introduction The aim: Materials : 466 The questionnaires had been distributed at shopping centres. The results of questionnaires were processed by the SPSS. Respondents were split into the following age groups: 18-30; 31-40; 41-50; 51- 60 and 61 years and older. Results of the survey were grouped by age . Results : The majority of respondents answered that "organic food is not necessary safe". Most of the participants in 18-50 age groups claim that the letter E marks preservatives, but older than 51 stated that the letter E marked the food products approved by the EU. The press, Internet and the radio were more often mentioned as the source of information about healthy food and food additives by the participants of the age group of 41 years and older. The groups younger than 51 years old specified that the information received on food and additives was not sufficient. The majority of respondents thought that the main food safety risks were microorganisms, pesticides, and chemicals, BSE, while the 61 and older – that GMO, acrylamide, and irradiation. Conclusions : The research demonstrates that consumers are insufficiently informed on proper nutrition, safe food products, different food additives and pol-lutants that may pose a potential risk to public health. The present survey has the potential to form an opinion of how Lithuanian consumers assess the food safety. This study is low-budget and easy to analyse; moreover, we believe that it could be modified appropriately to fit the assessments and habits of other populations, too.


Climate policy addresses a global problem, with costs and benefits distributed unevenly around the world. Questions of efficiency and equity are central to the allocation of costs; they are typically handled either by modeling optimal policies based on economic efficiency, or by setting standards that embody principles of equity. In this analysis, we employ our Climate and Regional Economics of Development (CRED) integrated assessment model to assess the optimal international allocation of effort. We compare CRED scenarios to the results of an equity-oriented burden-sharing framework, Greenhouse Development Rights (GDRs), which allocates effort to countries based on their responsibility (emissions) and capacity (income). We calibrate CRED to generate a scenario comparable to the GDRs reference case, or business as usual. We then recalibrate CRED to generate a mitigation scenario comparable to the GDRs emergency reduction scenario, which preserves a high likelihood of staying below 2°C. Finally, we compare the share of global effort allocated to high-income countries in the CRED mitigation scenario and the GDRs emergency reduction scenario, finding them to be similar in both models.

In year 2010, the foot-and-mouth disease spreaded all over the country in Korea, and approximately 3,000,000 animals were killed and more than 4,800 carcass burial sites were urgently made. Inside the carcass burial sites, sulfur-containing odor compounds such as hydrogen sulfide and dimethyldisulfide (DMDS) were produced by anaerobic microorganisms. In this study, a non-thermal plasma (NTP) system was applied for the removals of sulfur compounds emitted from carcass decomposition. Especially, the effects of relative humidity on the hydrogen sulfide and DMDS removals in the NTP reaction was evaluated. When relative humidity increased form <5% to 90% in the inlet odor-containing gas stream, the amount of ozone produced also increased, so that the hydrogen sulfide and DMDS removal efficiency increased as well. Based on the Gibb's free energy calculations for the ozone reactions with hydrogen sulfide and DMDS, the oxidation potential of DMDS with ozone was much stronger than that of hydrogen sulfide ; therefore, DMDS was first removed by ozone, and hydrogen sulfide was further oxidized in the following catalyst bed.


In this article, we consider the problem of developing a rational competitive design of a multifunctional all-terrain vehicle (MATV) with 8х8 axle configuration. Empirical dependencies are proposed to calculate weight-size parameters of these vehicles, such as power and power-to-weight ratio, payload, maximum speed, average ground pressure depending on full vehicle weight. Key dependencies are provided to calculate hydrostatic transmission (HST) parameters used to determine hydraulic unit sizes and connection diagrams. Various HST control algorithms are analyzed in order to increase efficiency and reduce fuel consumption. The results show that the right HST control algorithm can increase efficiency by 10%, and reduce fuel consumption by 18%. General view of the developed MATV is provided.


The study we describe here, an ethnographic investigation of the cognitive work of three programming teams, led us to emphasize an aspect of situatedness that is relatively unexplored: the developing perspective ofintellectual workers on their contexts of action. We followed teams composed of students in a Department of Computer Science as they were being taught "software engineering." Despite their subordinate position as students, we found that the institution was not totally successful in dictating their work; we could not assume a similarity of work activity across teams. Instead the teams' perspectives on their projects were collectively developed over the course of the project and they diverged. Consequently, the teams differed in their construal of the objects of their intellectual work and in the significance and time they devoted to the components of their work, and to the ways in which they carried them out. In this paper we recount these differences and relate them ultimately to ongoing tension...


There is a renewed interest in radar sensors in the autonomous driving industry. As a relatively mature technology, radars have seen steady improvement over the last few years, making them an appealing alternative or complement to the commonly used LiDARs. An emerging trend is to leverage rich, low-level radar data for perception. In this work we push this trend to the extreme -- we propose a method to perform end-to-end learning on the raw radar analog-to-digital (ADC) data. Specifically, we design a learnable signal processing module inside the neural network, and a pre-training method guided by traditional signal processing algorithms. Experiment results corroborate the overall efficacy of the end-to-end learning method, while an ablation study validates the effectiveness of our individual innovations.

A network is complete if every processor has a direct communication channel to every other processor. We consider the election problem on complete asynchronous networks when the processors are reliable while some of the channel s are subject to failure. In this paper, we have implemented Lokre's distributed election algorithm for faulty complete networks 1]. We built a complete network, designed the random generating software modules, and implemented the algorithm. We ran the program for several values of n and for various conngurations of the network. During each run we counted the number of messages passed, and the number of phases advanced before a leader was elected. For each value of n we did a best case, average case, and the worst case analysis of the number of messages passed. We compare the number of messages, and the number of phases advanced with the theoretical results. Doing this we show that the bounds proved by the algorithm are satissed.


The article examines the issues connected with the urgent need to overcome the uncertainty of information in a criminal case by the judge's search and cognitive means and the necessity to research the forensic-investigative situation. The conducted analysis substantiates the need to include into the conceptual apparatus of criminology the category of «problem-search forensic investigative situation» which is understood as the most mentalizing kind of investigative situation generated by the judges' (judge's) mental activity flowing in the information field, limited, on the one hand, by the materials of the preliminary investigation; on the other, by regimented procedure of the evidence examining in the hearing and decision on the merits. The conclusion is made about the allocation of the two phases of problem-search forensic investigative situation: 1. Statement of the main problem in the criminal case means to overcome the uncertainty of information. 2. The search of a problem solution, which should include search and cognitive means of judges (judicial tactics techniques) and forensic forecasting.

Combination logging runs that are possible with the SLAM system are presented to illustrate their application in a number of different geologic and borehole conditions. The advantages to performing combination logging runs are also discussed. Log presentations available are illustrated to demonstrate methods for displaying combination log data in usable formats. Diagnostic programs and troubleshooting aids are reviewed to demonstrate their ability to help predict when equipment is becoming marginal, and to minimize lost time due to equipment failure. Standard methods for performing instrument calibrations are described, including techniques to perform master calibrations at the shop or wellsite, as well as before and after wellsite checks performed with instruments suspended over the borehole, or on the catwalk.


The purpose of our investigation was to evaluate the effect of multiple transverse taeniamyotomy on sigmoid motility and on the clinical picture of 8 patients affected by symptomatic, uncomplicated diverticular disease of the sigmoid, selected for the operation after the failure of medical therapy. We recorded rectosigmoid intraluminal pressures and the manometric tracings were correlated with the corresponding photofluorograms before and after the operation for 1 year.


The technological evolution and the immensity of the data produced, circulated into company makes these data, the real capital of the companies to the detriment of the customers. The erroneous data put the knockout to relationships with customers, the company must address this problem and identify the quality projects on which it must make an effort. In this article, we will present an approach based on qualitative and quantitative analysis to help the decision-makers to target data by its impacts and complexities of process improvement. The Qualitative study will be a survey and a quantitative to learn from survey data to decide the prediction and the completeness of data.


In the present text, after describing what is known as symbolic interactionism and looking over this school of thought origins swiftly, as well as the main sociologists contributions to this current, born in the USA, we will try to figure out how it has influenced Spanish and Italian sociologist culture (media, manuals and researchers) and even if in poets and literary authors, as Gozzano and Pirandello, we can detect a meeting point with the interacionist sociology. To carry out this research, we have used a comparative-descriptive methodology, with techniques of data collection, document analysis (quantitative and especially qualitative content analysis types). The results show that it is a sociological school that has had compared to other countries, little spaces in Italy and Spain until this moment.


Governments situated on the same level of a multi-level governmental system compete with each other as well as with those placed higher or lower. This paper is concerned with horizontal competition only. It discusses both competition based on the mobility of agents (individuals, business firms, or factors) and competition related to the circulation of information. With regard to the first kind, it focuses on the capacity that governments keep to decide their policies and compete in spite of the mobility of agents. Some attention is also given to the implications of some non-standard assumptions about the underlying political set-up. The discussion of information-based competition includes that of "laboratory federalism" (whether decentralization favours innovation) and of "yardstick competition" (what are the effects of comparisons of governments' comparative performance across jurisdictions). Some questions pertaining to the relationship between the different forms of horizontal competition and to their normative and empirical dimensions are addressed briefly.


A numerically efficient approach to the problem of automatically segmenting images into regions of statistical stationary is proposed in this paper. The technique is fully unsupervised, in that no prior knowledge of the number of regions, or their attributes, is required. Instead, this knowledge is inferred via a dynamic learning phase. Specifically, image features are extracted from windows forming a tessellation of the image, by fitting the realization in each window with a Gaussian Markov Random Field. An approach to cluster formation in feature space is described, based on a finite Gaussian mixture model. This phase of the algorithm permits a threshold parameter - and subsequently, the number of texture classes and their parameters - to be inferred. A very fast approach to fine segmentation - which uses the result of the clustering phase as inputs - is then implemented, yielding a class label inference for a dynamically-chosen sparse set of pixel sites. The scheme is iterated to convergence, yielding a label realization for all pixel sites.To further enhance the identification of textural borders, a post-processing algorithm, using ICM-based estimation, is activated in areas of high edge activity, using the results of the previous stages as estimates of the label realizations in such areas. The performance of the scheme in synthetic and real image contexts is considered.


The concept of biorefinery technology and integrated forest biorefinery (IFBR) factory was introduced. The main principle of turn- ing traditional kraft pulp and paper mill into a IFBR factory was analyzed and three kinds of IFBR factory production models were concluded, which includes the near-neutral hemicellulose pre-extraction plus pulping process, the acid pre-hydrolysis plus pulping process and the alkali pretreatment plus cellulose fermentation process. The IFBR factory model remaining pulp production capacity shall be the main choice in near future, which can bring additional economical income for typical kraft pulp and paper mills. The pre-extraction liquor of wood chips before traditional pulping can be used to produce ethanol, acetic acid and other chemicals. The pre-extracted wood chips are continuously transported into the next production unit to produce pulp and paper products. No adverse effects of the pretreatment on strength and optical properties of the pulp are observed. The rate of return on investment of transforming a kraft mill into IFBR factory varies between 7.1% and 13.0%. According to the characteristics of paper industry of our country, turning forest paper mill into IFBR will follow the development model of remaining pulping and also it is advantageous and possible to turn grass paper mill into IFBR.


We show that for almost every frequency ?? ?? R\Q, for every C?O potential v : R/Z ?? R, and for almost every energy E the corresponding quasiperiodic Schr?Nodinger cocycle is either reducible or nonuniformly hyperbolic. This result gives very good control on the absolutely continuous part of the spectrum of the corresponding quasiperiodic Schr?Nodinger operator, and allows us to complete the proof of the Aubry-Andr?Le conjecture on the measure of the spectrum of the Almost Mathieu Operator.


Abstract

The purpose of present correlational study was to investigatethe relationship between verbal and non-verbal memory, information processing, and response inhibition with facial expression recognition in patients with schizophrenia. The participants of the present studyselected through the available sampling method including60 patients with different type of schizophrenia,patientswith paranoid(n =30) and patientswith disorganized(n=30).The emotion facial expression recognition test, Wechsler memory test, Stroop test and information processing questionnaire were administered. To analyze the data,Pearson correlation coefficients and multivariate regression analysis with stepwise method were employed. Result of the study revealed that there is significant positive correlation between verbal memory and information processing with facial expression recognition (P<0/05 & P<0/01). Nevertheless there is significant negative correlation between response inhibition with facial expression recognition (P<0/01). Result of the multivariate regression analysis showed that, only response inhibition can predict death facial expression recognition in patients with schizophrenia. To conclude, the results of studymay have important implications in the field of psychopathology and treatment of patients with schizophrenia.


The effect of implanting Ar+ ions into Ni films (as opposed to Fe films) on magnetic moment is discussed. The magnetic moment decreased gradually at doses of 1 × 1015 ions/cm2 or less and decreased suddenly beyond 3 × 1016 ions/cm2. These doses eventually reduce surface tension. Higher doses convert this internal stress back into surface tension. These results support the model that the formation of Ar bubbles generates new Ni interfaces and that this formation of interfaces decreases the Ni magnetic moment.


Many researchers use a time-lagged or loosely coupled approach in solving the Navier?Stokes equations and two-equation turbulence model equations in a time-marching method. The Navier?Stokes equations and the turbulence model equations are solved separately and often with different methods. In this paper a strongly coupled method is presented for such calculations. The Navier?Stokes equations and two-equation turbulence model equations, in particular, thek-? equations, are considered as one single set of strongly coupled equations and solved with the same explicit time-marching algorithm without time-lagging. A multigrid method, together with other acceleration techniques such as local time steps and implicit residual smoothing, is applied to both the Navier?Stokes and the turbulence model equations. Time step limits due to the source terms in thek-? equations are relieved by treating the appropriate source terms implicitly. The equations are also strongly coupled in space through the use of staggered control volumes. The method is applied to the calculation of flows through cascades as well as over isolated airfoils. Convergence rate is greatly improved by the use of the multigrid method with the strongly coupled time-marching scheme.

Video summarization offers an intelligent way of reducing the video content temporally to satisfy the user preference for a shorter viewing time, and/or to meet the bit budget limitations in storage/communications. In this paper we formulate the summarization problem as a rate-distortion optimization problem under bit budget and frame skip constraints, and introduce a summarization distortion metric that is based on the average frame distortion caused by dropped frames. An optimal summarization solution is therefore developed based on Lagrangian relaxation and dynamic programming. The simulation results demonstrate the effectiveness of the proposed summarization technique.


While applying the Rupp-Schied-Thiel1, 2 thiocyanate procedure to pathological urines, cancerous, and non-cancerous and to normals, as given in the preceding paper, the question arose as to the degree of specificity of the reaction when applied to a number of substances knbwn to occur in urine or possibly there. Among the substances possibly in urine found to behave like thiocyanate in the Rupp-Schied-Thiel procedure are ergothioneine, urinary protease, and oxyproteic acids, and to some degree uric acid. Four normal urines were studied for total apparent thiocyanate by the Rupp-Schied-Thiel procedure; for ergothioneine-like material color-imetrically against blood ergothioneine by the Behre and Benedict 3 procedure; urinary proteose by the method of Oriel and Barber 4 ; and for oxyproteic acids as barium salts according to Pregl. 5 In each case the thiocyanate equivalent of the fractions, (1) ergothioneine-like material, (2) proteose, and (3) barium oxyproteic acids was determined in the Rupp-Schied-Thiel procedure. The thiocyanate equivalents of fractions listed subtracted from the total apparent thiocyanate shows much less thiocyanate than given by the Rupp-Schied-Thiel method. The conclusion is drawn that the Rupp-Schied-Thiel method is not a measure of thiocyanate if applied directly to the urine. The same objection holds for the Munk 6 gravimetric method which depends on the precipitation of thiocyanate by silver nitrate and melting the precipitate with sodium carbonate and potassium nitrate to oxidize the sulfur to sulfate, which is then precipitated as barium sulfate. Other urinary sulfur compounds than thiocyanate are included in this method. The interfering material, however, can be eliminated. Thus, based on the findings that strong alcohol does not dissolve certain interfering substances such as ergothioneine, proteose, the barium salt of oxyproteic acid, or barium urate but does dissolve barium thiocyanate a somewhat improved procedure has been employed as follows: An aliquot of urine generally 50 cc. is treated with a saturated aqueous solution of barium hydroxide as long as a precipitate forms.


An automatic mesh generating technique capable of producing meshes with rapidly varying nodal densities has been devised which enables any number of nominated regions in the model to be emphasised. The technique is particularly suitable for establishing the mesh required for finite element analysis of the stress concentrations created by inclusions in high strength steels where mesh intensification is required at the inclusion sites. The method of nodal density specification is particularly suitable for iterative solution and apart from its usefulness in the present work on inclusions offers a perfectly general approach to automatic mesh generation in the continuum.


Richard Florida (2012) envisioned an emerging new social and economic order on the ruins of the world economy shaken by the global crisis. According to his revised theory, the creative economy and the creative class are going to play an essential role in shaping this new order. Thus, the creative class will basically contribute to the evolution and operation of more liveable and sustainable cities in the future. This is exactly why it is essential to explore and research the characteristics and mobility issues of the creative class, and the way it functions. In recent years, several macro-analyses have been published about the Hungarian creative economic situation; however, only a limited number of empirical results are available regarding the characteristics of the creative class on regional and local levels. We intend to begin to fill this gap with our new findings on the creative workers in Pecs, a regional centre located in a disadvantaged part of Hungary. This study aims, on the one hand, to explore those factors influencing the settling-down of the creative class in Pecs, and, on the other hand, to highlight work attitudes of local creative professionals. The novelty of our study is that micro-level (municipal, urban) analyses on the role of the creative economy and creative class are still missing in the Hungarian literature. Our outcomes are partly based on the analyses of the statistical database provided by the National Accounts Department of the Hungarian Central Statistical Office. Based on spatial analyses we have been able to provide detailed information on the size and composition of the creative class in Pecs. Other research presented in the paper is based on an online questionnaire survey conducted among the creative employees living and working in Pecs. The survey was carried out in 2014, and the questionnaire contained 43 closed and open questions (n=110). The analysis of statistical data showed that, over the last fifteen years, significant restructuring took place within the Hungarian creative class in favour of knowledge-driven industries. In the early 2000s, the number of creative companies and employees as well as revenues increased dynamically, but the economic crises broke the momentum and hit the creative industries first. A similar process took place in Southern Transdanubia, and in Baranya County as well. Actually, within the region, the county of Pecs appears as the only engine of the creative economy. However, for nearly a decade the city's creative economy and creative class has also been shrinking. In practice, knowledge-intensive branches and especially RD however, as time goes by its importance increases significantly. For creative people the joy of work is the primary source of job satisfaction. With regard to the breakdown of satisfaction by industries, the role of motivating factors is the highest in branches where work is carried out in the traditional sense of creative work, while satisfaction in innovative and knowledge-intensive industries is dominated by hard factors. Creatives working as employees and in bigger companies prefer hard factors, while self-employed ones working for small- and micro-enterprises favour motivating factors. According to our empirical findings, the main expectations of creative newcomers towards the city is to maintain a proper labour market providing a sufficient number of quality workplaces and jobs, while creatives already wellembedded in the local labour market require more options to improve their personal networks and relationships.


Valve morphogenesis in two Surirellae (S. ovalis Brebisson and S. robusta Ehrenberg) is described. Mitosis takes place at the broad end of the cell. After cleavage, a new Microtubule Center (MC) arises near each spindle pole and moves to the adjacent plasmalemma. Soon, a specific group of microtubules (MTs) extends from very near the MC around the periphery of the cell. Concurrently, the new tubular Silica Deposition Vesicle (SDV) grows around the periphery of the cell close to these MTs. A double rib of silica is rapidly formed inside the SDV; the space between the ribs becomes the raphe. Mitochondria line up along the MTs, and the SDV may be molded around these to create the canal raphe. Soon, the SDV expands in two directions to create the face and the mantle of the new valve. Meanwhile, each daughter nucleus, accompanied by the MC, moves to its interphase position at the center of the cell; this movement is colchicine‐sensitive. As in several other pennate diatoms, an interruption in the raphe of the mature valve coincides with the initial position of the MC. The canal raphe thickens rapidly around the mitochondria; a rudimentary raphe fiber may be associated with the creation of a tiny curvature at the inner raphe fissure. As the SDV expands in the large S. robusta, the daughter cell protoplasts slowly shrink by plasmolysis, thereby creating the complex curved surface of the new valve surmounted by the arching canal raphes which are now quite rigid. In S. ovalis, the daughter cell protoplasts remain appressed and therefore the new valve surface is basically flat.

This chapter provides an introduction to naturally occurring methane hydrates: their physical properties, formation, occurrence, and distribution in the natural environment, current estimates of resources, and potential for exploitation. The hydrate stability zone (HSZ) in marine and subsurface permafrost sediments can be delineated as the overlap of the pressure-temperature region of hydrate thermodynamic stability and the hydrothermal/geo-thermal gradients. In both marine and permafrost sediments, within the region of pressure-temperature stability, gas hydrates may form wherever the concentration of methane exceeds solubility in pore waters. The chapter summarizes the principal metabolic pathways involved in methanogenesis. The most important substrates for bacterial methanogenesis are acetate and H 2/CO2/. Until recently, probably the most widely cited global estimate of hydrate-bound gas was 21 × 1015 m3 of methane (STP) or ~10,000 gigatons of methane carbon. The success of the initial field studies at Mallik well led to a second research program, the Mallik 2002 consortium, this time with the aim of investigating methane production. The forecast for future tight supplies of natural gas, along with increasingly higher prices, point to growing demand for alternative supplies. The exploitation of gas hydrates is seen by many as a means to meet the demand, with some analysts suggesting that marine gas hydrates may begin contributing to natural gas markets in less than 10 years.

The invention discloses a device and method for operation fault diagnosis and safety pre-warning for a medium-low pressure fuel gas pressure regulator. The device for the operation fault diagnosis and the safety pre-warning for the medium-low pressure fuel gas pressure regulator comprises two pressure measurement transmitters, a field data recorder, and a data processing and fault diagnosis main unit. The two pressure measurement transmitters are arranged on a pipeline on one side of a medium pressure fuel gas pipeline and a pipeline on one side of a low pressure fuel gas pipeline respectively, and the data output ends of the two pressure measurement transmitters are connected with the field data recorder. According to the working modes, offline fault diagnosis comprises the steps that the field data recorder is in timed connection with a mobile type data unit to transmit field data, and then the field data are copied to the data processing and fault diagnosis main unit; online fault diagnosis comprises the steps that the field data recorder transmits the data to a data communication unit connected with the field data recorder, and the data communication module sends the data to the data processing and fault diagnosis main unit in a wired communication mode or a wireless communication mode. The device and method for the operation fault diagnosis and the safety pre-warning for the medium-low pressure fuel gas pressure regulator can achieve the technical effects that the safety data of the medium-low pressure fuel gas pressure regulator are collected and processed in real time, and faults are diagnosed automatically.


This article examines first to second language (L1-to-L2) phonetic transfer in the speech of ten Occitan–French bilinguals, focusing on the mid-vowels in each of their languages. Investigating transfer in a situation of long-term societal language contact aims to shed light on the emergence of regional French phonological features from contact with Occitan. Using a sociophonetic methodology, the concept of equivalence classification (Flege 1988) is investigated, that is, that L2 words will be (initially) decomposed into familiar L2 sound categories, causing L1 and L2 sounds to resemble each other phonetically. The consequences of language contact are modelled statistically using an original corpus of over 1200 vowel tokens. The findings show that equivalence classification may not lead to equated sounds coming to resemble each other phonetically, suggesting necessary revisions to the speech learning model (SLM) hypothesis, and the need to consider the influence of sociolinguistic factors in situations of long-term language contact is emphasised.


An unusually exacting independent reanalysis has confirmed the findings of earlier studies that the number of deaths from heart and lung disease increases as air pollution increases. This new confirmation raises the pressure on the Environmental Protection Agency to tighten air pollution standards. "We've known through the centuries that air pollution can kill—take the deadly London fogs, for example," says Jonathan M. Samet, chairman of the department of epidemiology at Johns Hopkins University's School of Hygiene & Public Health in Baltimore. "What's caused controversy recently is that effects are being observed at air pollution levels we once would have considered safe, levels that are below the national standards." Samet is one of three coauthors of the reanalysis, which reexamined six earlier studies that had linked measured indexes of particulate air pollution to increased mortality. Those studies, published in the early 1990s, were the driving force behind the American Lung Association's (ALA) deci...


OBJECTIVE: This study aimed to examine the differences between baseline reaction time scores in collegiate, high school, and middle school athletes using a clinical measure of simple reaction time.
BACKGROUND: There are as many as 3.8 million mild traumatic brain injuries (mTBI) in the United States every year. Impaired reaction time (RT) is a common indicator of cognitive change after mTBI, and clinical measures of RT can be a valuable tool in a multifaceted sports concussion assessment battery. Assessment of simple RT utilizing the RTclin drop-stick may be a reliable clinical test with high specificity and sensitivity to the acute effects of concussion in collegiate athletes.
DESIGN/METHODS: A group of 1,376 baseline RTclin scores from the University of Michigan, UCLA, and partnering high schools and middle schools were compiled in a de-identified database. Baseline RTclin scores were recorded for all athletes prior to their competition season. Mean RTclin score was calculated as an average fall time prior to catch for eight trials. Statistical analysis was performed using EpiTools: R Package for Epidemiologic Data and Graphics (version 3.0).
RESULTS: Average RTclin in collegiate athletes (209.3ms) differed significantly (P<0.001) from both high school (202.9ms) and middle school (199.1ms) scores. Average RTclin was significantly different between males (202.9ms) and females (216.1ms) (p<0.001). Among high school and middle school athletes who reported a prior history of concussion, there was no significant difference in average RT (p=0.4).
CONCLUSIONS: Average RT scores were slower in older age groups. On average collegiate and high school females had slower RT scores than their male counterparts. There does not seem to be a relationship between a prior history of concussion and average RT scores. Results could be valuable in the assessment of injured athletes without a prior baseline RTclin score. Disclosure: Dr. Zeiger has nothing to disclose. Dr. Choe has nothing to disclose.

Purpose:This study was performed to investigate the effects of somatosensory training on the spatiotemporal gait parameters and balance in patients with stroke patients. Methods:24 stroke survivors were allocated in this study, and randomly divided into experimental(n=12) and control group(n=12), independently. Experimental group was applied somatosensory training program plus conventional physical therapy, and control group was applied only conventional physical therapy. All subjects were administered for 30 minutes per day during 8 weeks (5 times a week). Results:Spatiotemporal parameters of gait were significant difference between pre and post intervention in experimental group, except of step length asymmetry ratio(SLAR) and single support time asymmetry ratio (SSAR)(p .05). And also there was significant difference between experimental and control group (p .05). Balance parameters were significant difference between pre and post intervention in experimental group (p .05). And experimental timed up and go test was significantly decreased than control group (p .05). Conclusion:This study was suggested that somatosensory training has effectiveness on the spatiotemporal gait parameters and balance in patients with stroke survivors, So this therapeutic intervention will be effectively apply to the stroke survivors in the clinical setting.


We study the response of star clusters to individual tidal perturbations using controlled N-body simulations. We consider perturbations by a moving point mass and by a disc, and vary the duration of the perturbation as well as the cluster density profile. For fast perturbations (i.e. 'shocks'), the cluster gains energy in agreement with theoretical predictions in the impulsive limit. For slow disc perturbations, the energy gain is lower, and this has previously been attributed to adiabatic damping. However, the energy gain due to slow perturbations by a point-mass is similar to, or larger than that due to fast shocks, which is not expected because adiabatic damping should be almost independent of the nature of the tides. We show that the geometric distortion of the cluster during slow perturbations is of comparable importance for the energy gain as adiabatic damping, and that the combined effect can qualitatively explain the results. The half-mass radius of the bound stars after a shock increases up to ∼7 per cent for low-concentration clusters, and decreases ∼3 per cent for the most concentrated ones. The fractional mass loss is a non-linear function of the energy gain, and depends on the nature of the tides and most strongly on the cluster density profile, making semi-analytic model predictions for cluster lifetimes extremely sensitive to the adopted density profile.


A comprehensive flight test study involving an advanced flow field measurement technique, a particle
sizing system as well as a conventional single‐point measurement system is herewith presented.
The main objective of this campaign was the assessment of the accuracy and performance of Particle
Image Velocimetry under flight test conditions. Hence, a PIV system was arranged inside a DLR research
aircraft to determine the boundary layer flow close to the fuselage surface. In addition, a traversable
rake with two differential pressure probes was installed close to the field of view of the two
stereoscopic PIV cameras to measure the velocity in a conventional and reliable way. The seeding
source for the PIV system were naturally occurring hydrometeors like cloud droplets, haze or precipitation.
The behaviour of these tracer particles with varying diameters inside the examined boundary
layer is to a certain extend unknown. Hence, a particle sizing system based on the Interferometric
Laser Imaging for Droplet Sizing (ILIDS) technique was also introduced, designed and certified to allow
a derivation of the particle dynamics during the PIV measurements.


The development of fourteenth- and fifteenth-century sacred polyphony is linked closely not only to the Mass and divine services of the Roman Catholic Church, but equally to the rise of lay devotional congregations who sponsored their own services, often musically elaborate, at private chapels and altars. Within this popular phenomenon of lay devotion in the Low Countries, several northern confraternities can be cited for their very early regular use of polyphony. A polyphonic Salve service was established in 1362 by the Marian confraternity at St Goedele in Brussels, and Reinhard Strohm has shown that, by 1396, the Marian Guild of the Dry Tree (Ghilde vanden droghen Boome) in Bruges sponsored weekly masses sung in polyphony by its guild members. That polyphony was central to some fourteenth-century confraternity services is confirmed by the records of the Illustrious Confraternity of Our Lady in 's-Hertogenbosch, founded in 1318 in St John's Church.

Gliogenesis requires the careful orchestration of migration, differentiation, and proliferation of progenitors. Signaling through the epidermal growth factor receptor (EGFR) has been implicated in regulating these processes in a variety of cell types, including neural progenitors. By retroviral infection, we constitutively expressed an EGFR-GFP fusion protein in white matter glial progenitors at postnatal day 3 of the rat forebrain in vivo and analyzed the development of these cells over the subsequent 15 weeks. EGFR-GFP+ cells remained proliferative and migratory, gradually populating the brains ipsilateral and contralateral to the side of viral infection, but never differentiated into mature glia. The accumulation of these cells doubled the total cell density in white matter and led to a 10-fold increase in the abundance of glial progenitors, giving rise to a progenitor "hyperplasia." The marker profile of infected cells, NG2+, olig2+, PDGFR-α+, nestin+, GFAP−, and CC1−, indicated a close resemblance to oligodendrocyte progenitors. Positive immunostaining for phosphorylated EGFR colocalized with punctate accumulation of EGFR-GFP, indicating that a subset of receptors was engaged in active signaling. Furthermore, EGF was required to observe phospho-tyrosine EGFR immunostaining of glial progenitors in culture. These observations suggest that constitutive EGFR expression can inhibit glial differentiation, but requires ligand as well.

The effects of intra external iliac arterial infusions of leucine (114 μmol h−1 kg0.75) and insulin (0.34 U h−1 kg0.75) into the hindlimb on net whole blood branched-chain amino acid (BCAA), plasma branched-chain α-keto acid (BCKA) and glucose exchange across the hindlimb (HL) and portal-drained viscera (PDV) were investigated in chronically catheterized cattle. Leucine infusions increased (P < 0.05) arterial leucine and α-ketoisocaproate concentrations but did not affect the concentrations of other BCAA, BCKA or glucose. Leucine infusions resulted in a 4-fold increase (P < 0.1) in the net HL removal of leucine and a small increase (P < 0.1) in the net HL release of α-ketoisocaproate. Net whole blood BCAA, plasma BCKA and plasma glucose exchange across the PDV were unaffected by leucine infusions. Insulin infusions decreased (P < 0.1) whole blood leucine, plasma α-ketoisocaproate and plasma glucose concentrations and increased (P < 0.1) the HL extraction of plasma glucose. The HL and PDV extraction of who...

The increase in human population as well as area development in Salatiga Groundwater Basin, Central Java Province, will increase the potency of groundwater contamination in that area. Groundwater quality, especially the shallow groundwater, is very vulnerable to the contamination from industrial waste, fertilizer/agricultural waste, and domestic waste. The first step in the conservation of groundwater quality is by conducting the mapping of the groundwater vulnerability zonation against the contamination. The result of this research was groundwater vulnerability map which showed the areas vulnerable to the groundwater contamination. In this study, groundwater vulnerability map was assessed based on the DRASTIC Method and was processed spatially using Geographic Information System. The DRASTIC method is used to assess the level of groundwater vulnerability based on weighting on seven parameters, which are: depth to the water table (D), recharge (R), aquifer material (A), soil media (S), topography (T), impact of vadose zone (I), and hydraulic conductivity (C). The higher the DRASTIC Index will result in the higher vulnerability level of groundwater contamination in that area. The DRASTIC Indexes in the researched area were 85 – 100 (low vulnerability level), 101 -120 (low to moderate vulnerability level), 121 – 140 (moderate vulnerability level), 141 – 150, (moderate to high vulnerability level), and 151 – 159 (high vulnerability level). The output of this study can be used by local authority as a tool for consideration to arrange the policy for sustainable area development, especially the development in an area affecting the quality of Salatiga Groundwater Basin.


The following presentation introduces a case of a patient with the restless genital syndrome. This is a rare, usually undiagnosed condition, in which significant organ damage and/or dysfunction is absent, the finding is defined as functional and the patient is referred for treatment of his neurosis in a psychiatric practice. The complaints include feeling of arousal and tingling in the genital area, which is not accompanied by subjective sexual arousal and is a harrowing experience for the patient. Masturbation and sexual activity do not manage to affect the symptoms. Symptoms of restless leg syndrome are often involved too, which puts the hypothesis for a common etiology of both of the syndromes that is associated with the dopaminergic mediation. In the literature, there are individual cases of patients with the syndrome, who have been administrated treatment with pramipexole. The patient in the present case report has also undergone treatment with pramipexole and has been observed for a period of two years.


Abstract This study explores how social inclusion and exclusion manifest as a dynamic continuum in the everyday lived realities of irregular migrants. Based on narratives of Iraqi Kurdish asylum seekers, who were eventually deported from Finland, the analysis depicts the ways in which societal structures, personal negotiations as well as relationships and social networks interplay in lives characterized by multiple locations, transitions and positions. Establishing and maintaining social contacts, belonging to various networks and being able to decide and act are primary factors that help us understand how the narrators relate to the continuum. The participants construct narratives illustrating several viewpoints or positions regarding participation, agency and dependency on outside actors and networks.


Solar geoengineering by deliberate injection of sulfate aerosols in the stratosphere is one of the proposed options to counter anthropogenic climate warming. In this study, we focus on the effect of a specific microphysical property of sulfate aerosols in the stratosphere: hygroscopic growth—the tendency of particles to grow by accumulating water. We show that stratospheric sulfate aerosols, for a given mass of sulfates, cause more cooling when prescribed at the lower levels of the stratosphere because of hygroscopic growth. The larger relative humidity in the lower stratosphere causes an increase in the aerosol size through hygroscopic growth that leads to a larger scattering efficiency. In our study, hygroscopic growth provides an additional cooling of 23% (0.7 K) when 20 Mt‐SO4 of sulfate aerosols, an amount that approximately offsets the warming due to a doubling of CO2, are prescribed at 100 hPa. The hygroscopic effect becomes weaker at higher levels as relative humidity decreases with height. Hygroscopic growth also leads to secondary effects such as an increase in near‐infrared shortwave absorption by the aerosols that causes a decrease in high clouds and an increase in stratospheric water vapor. The altitude dependence of the effects of hygroscopic growth is opposite to that of sedimentation effects or the fast adjustment effects due to aerosol‐induced warming identified in a recent study.


This article will show you how to measure the position and momentum of a particle simultaneously from the principle of uncertainty .From the principle of position-momentum uncertainty, the position and momentum of a particle can be determined at the same time by fulfilling the condition of uncertainty by multiplying a constant k with the fixed value of position and momentum. Which is known as the principle of certainty.


The method of controlling chaos by occasional nonlinear time-delayed feedback is proposed. Through the numerical analysis of bifurcation diagram and Lyapunov exponent, we found that the systematic chaos can be controlled effectively by the nonlinear time-delayed feedback as the form of u(xn,xn-k)=cxnxn-k. Under the proper feedback coefficient c, time-delayed coefficient k and occasional feedback period N, the system could be controlled from chaos to the steady periodic orbit, and also the steady period is the integral multiple of the occasional feedback period N.


Alternative delivery applications are gaining popularity today, and parcel lockers are differentiated from others as they offer different delivery location options to customers. One of the biggest problems faced by courier companies today is that customers are not always available at the place of delivery during delivery. This leads to an increase in failed deliveries that place an extra burden on last mile operations, not only in terms of cost, but also in terms of environmental concerns. One of the effective methods to deal with this problem is parcel lockers. Parcel lockers and related concepts are currently used in various countries worldwide, and in some countries, their installation and use are supported by the government. Parcel lockers not only help logistics companies navigate their operations and costs, but also give the customer the power of choice. Therefore, it is considered necessary to investigate the parcel locker applications in Turkey. This paper intends to present the current state of parcel lockers in Turkey, the companies providing the service, their profiles, and their plans to provide beneficial knowledge to academia and industry.


Cooperative driving systems are a possible solution to improve traffic efficiency, road safety and even reduce the emission of pollutants, but there are several problems relating to aspects of safety, cost, duration and feasibility that slow down the development and experiments. In this context, simulation tools are essential to help researchers on this development. The goal of this paper is to present our simulator framework for cooperative vehicle systems and also a test case for validation. This framework is an integration among open-source tools which is composed by real-time robotics simulator and network simulator. The test case is a simulation which implements the Cooperative Adaptive Cruise Control (CACC) that uses both vehicle control and communication. The simulation is based on an approach Leader -- Follower with four vehicles, using a Preceding Communication Topology. The proposed Framework allows evaluating the delay time effect on CACC communication systems and also validating the control performance, taken into consideration the distance and velocity of the simulated vehicles.


Archaeological interventions in the last few decades in the city of León, where the Legio VI Victrix and the Legio VII Gemina were located during the Early Roman Empire, have uncovered a considerable amount of Roman pottery. Among these findings, particularly noteworthy are some Eastern Mediterranean amphorae and an important set of glazed pottery from Asia Minor workshops. Analyses of the set reveal the basic products that were habitually consumed in the fortress, in particular, Eastern Mediterranean wines, and prestigious products such as glazed pottery, particularly two skyphoi that present a curious iconographic motif related to the trial of Orestes.


Soil is an inexhaustible source of microorganisms of significant interest to biotechnology. Bacteria are able to control the growth of pathogenic microflora, stimulate plant growth, and decompose pollutants of varying degrees of toxicity. Bacteria make a significant contribution to the cycle of substances. The aim of this work was to isolate aerobic microorganisms from soil samples of two types - forest, without technogenic history, and agro-industrial, and to evaluate their properties. 15 strains of bacteria were isolated from forest soil, of which representatives of the genera Rhodococcus, Bacillus, Arthrobacter, Paenibacillus, Pseudomonas, Acinetobacter were able to degrade such persistent pollutants as chlorophenols, biphenyl and naphthalene. 77 strains were isolated from chernozem, of which 15 used benzoate as the sole source of carbon and energy. Thus, it has been shown that bacterial strains isolated from both forest and agricultural soil have a certain biodegradative activity, which allows them to reduce the level of pollution.


To reveal the protective and anti-apoptosis effect of compound Ginkgo biloba granules on oxidative stress injury of human umbilical vein endothelial cells (HUVEC). Negative control group, H2O2 model group and 4 drug pretreatment groups (80, 160, 320, 640 mg• L⁻¹) were established. The cell proliferation, morphological changes in each group after oxidative stress injury was detected by MTT assay and through microscope observation respectively. The content of LDH, MDA, SOD and NO and SOD activity in supernatant were detected to judge the protection effect of the drugs on endothelial cells. The protective effect on HUVEC apoptosis was analyzed by Caspase-3 activity test and Annexin V-FITC/PI staining. Western blot was used to observe the expression of apoptosis-related proteins Bcl-2 and Bax. Results showed that 1 200 μmol• L⁻¹ H2O2 can induce oxidative stress injury in endothelial cells and reduce the cell survival rate; cell proliferation inhibition degree is positively correlated with the effect time of H2O2. Besides, 80, 160, 320 640 mg•L⁻¹ compound Ginkgo biloba granules can protect HUVEC from oxidative stress injury, recover the normal proliferation level of cells, improve their state, prohibit cell apoptosis, and can up-regulate and down-regulate the expression level of Bcl-2 and Bax respectively. In conclusion, compound G. biloba granules can protect HUVEC from the oxidative stress injury induced by H2O2, its mechanism may be correlated with inhibition of the mitochondrial apoptotic pathway in HUVEC.


I ncreased activity of the renin–angiotensin– aldosterone system (RAAS) plays an important role in the pathogenesis of chronic kidney disease (CKD) [1,2]. Inhibition of the RAAS with angiotensin-converting enzyme inhibitors (ACEis) and angiotensin II receptor blockers (ARBs) has beneficial effects in slowing the progression of renal injury. However, these agents do not always prevent end-stage renal disease (ESRD) [3]. Inhibition of renin, the first rate-limiting enzyme acting at the point of activation of the RAAS cascade, may provide different renoprotective effects than other RAAS-blocking agents [4]. Therefore, dual therapy of a renin inhibitor with an ACEi or an ARB might be beneficial in preventing ESRD. Aliskiren is the first orally active, nonpeptide, low molecular weight, direct renin inhibitor approved for the treatment of hypertension [5]. The efficacy of aliskiren on blood pressure reduction has been evaluated in animal experiments [6,7], as well as in patients with CKD [8] and diabetes [9]. The antihypertensive effect of aliskiren remains relatively long, even after treatment withdrawal [7], and is comparable or superior with that of other antihypertensive agents at recommended doses [10]. In streptozotocininduced diabetic (mRen-2)27 rats, aliskiren (10 mg/kg per day) does not reduce blood pressure as much as perindopril (0.2 mg/kg per day), but both drugs successfully reduce albuminuria and glomerulosclerosis [11]. Interestingly, aliskiren, but not perindopril, attenuates tubulointerstitial fibrosis, suggesting the significant renal tissue distribution of aliskiren [11]. Recently, we have also demonstrated that aliskiren augments antialbuminuric effects of an ARB in type 2 diabetic KKAy mice [12].

Classification of objects has been a significant area of concern in machine vision applications. In recent years, Support Vector Machines (SVM) is gaining popularity as an efficient data classification algorithm and is being widely used in many machine vision applications due to its good data generalization performance. The present paper describes the development of multi-class SVM classifier employing one-versus-one max-wins voting method and using Radial Basis Function (RBF) and Linear kernels. The developed classifiers have been applied for color-based classification of apple fruits into three pre-defined classes and their performance is compared with conventional K-Nearest Neighbor (KNN) and Naïve Bayes classifiers. The multi-class SVM classifier with RBF kernel has shown superior classification performance.

Abstract Ten guidelines in the form of "commandments" are offered to scientists and statisticians who testify before government bodies such as congressional committees, regulatory agencies, or judicial panels. These guidelines are illustrated by examples of testimony by the author and others. Efforts to communicate highly technical material to nontechnical audiences are often frustrated by communication breakdowns. These difficulties can be avoided by making simple statements in plain English, but this isn't so easy as it sounds. The commandments suggest that preparation and hard work are needed to avoid the mistakes that are commonly made in testimony.

The ATLAS liquid argon calorimeter housed in three independent cryostats containing a total argon volume of about 78 m has been installed in the underground cavern. The three detectors have been cooled down following stringent temperature gradient limits and have been filled with liquid argon. The cryostats are now in a stable condition for periods going up to almost two years. The temperature uniformity within each of the three detector volumes is found to be within 70 mK rms, while the temperature stability stays below 5 mK rms.


The synthesis of TiO 2 –chitosan nanocomposite photocatalyst using Titanium(IV)-Isopropoxide (TTIP) as precursors and chitosan as host material has been conducted. The synthesis was carried out using sol-gel method at room temperature and aging to grow crystal seeds and generate nanoparticles. The success of forming nano-sized anatase phase TiO 2 nanocrystal was strongly influenced by the sol pH system during hydrolysis and the aging time. The effect of sol pH system and aging time to the crystallinity level and particle size were examined using X-Ray Diffraction (XRD), Transmission Electron Microscopy (TEM) and Diffuse Reflectance UV-Spectroscopy (DR-UV). The results showed that TiO 2 produced in acidic pHs (pH 2-4) tended to have higher crystallinity level than that produced in weakly alkaline (pH > 6), which prone to be amorphous. The longer aging time (> 14 days) also tended to produce the amorphous phase. Furthermore, chitosan as a host material had a notable influence in determining the crystallinity level and particle size of TiO 2 in TiO 2 –chitosan nanocomposite.

Mixing Mg with Ti leads to an alloy with markedly faster hydrogenation kinetics as compared to that of pure Mg, but the resulting hydrides are too stable for hydrogen storage applications. Moreover, Mg−Ti alloys are thermodynamically unstable with respect to decomposition into the elements. In this Letter, we show by means of first-principles density functional theory calculations that adding Al or Si to Mg−Ti makes the alloys more stable and their hydrides less stable. Controlling the structure of Mg−Ti−X (X = Al or Si) alloys by growing multilayers of Mg and TiX allows for tuning the hydrogenation energy and improves the alloys as hydrogen storage materials.
