Some difficulties and suggestions as to some solutions in tackling the endogenous long-term dynamics of the geography of the economy are outlined. First is the breaking into history and positing initial conditions, an illogicality which appears inevitable. The philosophical background of endogenous change is discussed in terms of non-holonomic series. The notion of the "going concern," a term of MacKinder's, is introduced and an analogy made with the writing of a crossword puzzle; this is briefly summarized in terms of an entropy model. Then follows a brief scan of the similarities of this approach to the work which econorrric historians have done. Finally, development is conceived as random interactions between the scale components of maps.


Emergency Medical Service (EMS) responders deliver patient care in high-risk, high-stress, and highly variable scenarios. This unpredictable work environment exposes EMS responders to many risks, one of which is violence. The primary goals of this systematic literature review were to (1) define the issue of violence experienced by EMS responders and (2) identify the risk factors of violence associated with the EMS profession. An innovative inclusion of industrial literature with traditional peer-reviewed literature was performed. Of 387 articles retrieved, 104 articles were assessed and reviewed. Career exposure for EMS responders to at least one instance of verbal and/or physical violence was between 57 and 93 percent. There is a great need for rigorously designed, nationally representative examinations of occupational exposures in order to better understand the temporal associations of violence, cumulative occupational stressors, and the outcomes of physical and psychosocial injuries that are occurring as a result of exposures to violence.


In safflower (Carthamus tinctorius L.) breeding, determining superior pure lines after crossing for agro-technological traits is the first step to improve new cultivar candidates. Therefore, aim of the study was to determine superior pure lines of sufflower in F9-10 derived three intraspecific crosses evaluating the agronomical and technological (quality) traits. A total of 25 safflower genotypes including 15 pure lines was compared with 10 standard cultivars (Dincer 5-18-1, Centennial, Remzibey-05, Balci, Linas, Olas, Gelendost-2, Gokturk, Montola 2000 and W6 9822) and genotypes along with parents of lines for two years in 2017-2018. GEMO-20 had higher 1000-seed weight, GECE-8 and GEMO-20 had higher oil content, GEMO-19, 28 and GEW6-7 had higher oil yield, GEMO-28 and GEW6-7 had higher seed yield than standard cultivars. According to 1000-seed weight, oil content, seed and oil yield traits, GEMO-19, GEMO-20, GEMO-28 and GEW6-7 lines were identified as superior lines.

Objective: to evaluate the clinical performance of the dual shade layering and polychromatic resin composite layering techniques using a randomized controlled trail. Material and Methods: 42 participants (84 restorations) of class IV or class III through and through within a pair of anterior contra-lateral teeth   were randomly allocated into two groups according to technique of composite restoration placement: control "polychromatic layering" and intervention "dual-shade layering". Follow-up was done at 1 month (baseline) and 1 year. Restorations were evaluated using Visual Analog Scale (VAS), restoration color shade match using Vita Easyshade V ®, and blinded assessor using FDI criteria for assessment of dental restorations measuring (aesthetic properties). Chi-square test was used to compare between restorations of both techniques. Results: There was no statistically significant difference between restorations of both techniques for patient satisfaction outcome, restorations color match outcome, and for all tested FDI outcomes except surface luster with 100% success. Conclusion: Both dual-shade layering and polychromatic natural layering techniques, exhibited acceptable clinical and esthetic performance.

Christian Greuel We hear the talk of endless technological revolutions. We are surrounded by high-tech gadgetry that does our bidding. Yet what does all of this magnificent machinery really offer us? Does progress in fact exist? And if so, what is it actually worth without substantial content? This discussion panel is addressing the current state of aesthetics in the virtual environment by focusing on the roles that tools have played in artistic communities of the past and how virtual technologies will undoubtedly affect their future. The beginning of history shows human beings using naturally-made pigments to draw images on cave walls, allowing them to represent their experiences to others. Through tomorrow's technology, we may find ourselves projecting our very thoughts into the space around us in order to do exactly the same. The purpose of the aesthetic action has and always will be to visualize ideas and to explore our environments using whatever devices are available. Today we have increasingly powerful instruments, such as personal computer workstations, stereoscopic video displays and interactive software, to present artificially fabricated environments, popularly known as Virtual Reality. The technological elements are in place and we have begun our investigation into the latest and greatest form of artistic communication. Virtual Reality promises artists the most exciting breakthrough for the creative process since the invention of motion pictures. Now at the dawn of an era of virtual arts, the first generations of tools wait patiently to tell us something that we don't already know. But what message do they bring? Is there any passion here? High-end technology is not an end in itself. It merely represents the latest in a long list of tools that can be used for human expression. We have not come this far just to do cool computer tricks or sell vacant office space. There has been an unfortunate lack of artistic activity in cyberspace. We must focus on this cultural deficit and breathe life into the cold silicon void that we have created. By considering the tools of Virtual Reality in a historical context of art and technology as they relate to the fabrication of simulated experience, this panel of active artists intends to provoke constructive thought amongst the virtual arts community, promote active exploration of experience as an art form and unlock doors to possible roads for our artistic travels throughout this age of cybernetics.


The author analyses the Ust-Ilimsk citizens' memories about their childhood that took place in the period of late socialism. A special attention is paid to the everyday life which was formed by the family, street, state, and by the atmosphere of a young developing city. The research reveals the mechanisms of the child's personality formation and the process of acquiring universal values. The author arrives to the conclusion that it is impossible to consider childhood as a source of forming of the negative qualities of the Soviet person.


On October 31, 2008, at the American Academy of Religion's annual meeting, the Society for Buddhist-Christian Studies sponsored a well-attended afternoon session titled "Cognitive Science, Religious Practices, and Human Development: Buddhist and Christian Perspectives." This issue of Buddhist-Christian Studies contains three of the papers presented: Wesley J. Wildman's "Cognitive Error and Contemplative Practices: The Cultivation of Discernment in Mind and Heart," Noreen Herzfeld's "'Your Cell Will Teach You Everything': Old Wisdom, Modern Science, and the Art of Attention," and Robert Aitken's " 'Who Hears?' A Zen Buddhist Perspective." Each paper addresses in some way the connections between meditation and accurate perception. Wildman traces how cognitive errors rooted in innate perceptual biases give rise to mistaken beliefs and self-defeating behaviors. He highlights various ways religious practices both promote and ameliorate common cognitive errors. He claims some meditation practices are particularly effective in amelioration. While Wildman's paper gives detailed attention to various types of cognitive errors and ways to curb them, Herzfeld's and Aitken's papers have, in some ways, a broader focus. Both include material that suggests that meditation can clear, sharpen, and steady the overall perceptual lens though which humans interpret and construct all of their relationships. (Most contemporary neuroscience assumes that "what" is perceived is the relationship between the perceiver and the "object" of perception.) Herzfeld cites research suggesting that "empathy" is one socially beneficial characteristic of the "focused, close attention" developed by the solitary meditation practices of the Christian Desert Fathers. Aitken claims that Zen practice develops the attentiveness needed to perceive the "intimacy" between the perceiver and what is perceived. I suspect that the neurophysiology of attention behind Herzfeld's "empathy" and Aitken's "intimacy" is profoundly similar. Aitken, comparing Zen's emphasis on experiencing intimacy with Tibetan Buddhism's emphasis on developing compassion, points out that "Compassion by etymology is 'suffering with others'—the realization of social intimacy." "Compassion" is derived from Latin, while Herzfeld's


In the present work a numerical analysis of the \Radiver" test case was carried out using CFD techniques. \Radiver" is a centrifugal compressor stage for which a large amount of experimental data are available for ten diuser congurations. Two diuser geometries, diering in the radial gap between impeller exit and diuser inlet, were compared in order to investigate the impact of impeller{diuser interaction on the stage performance and the o w eld. Both steady and unsteady computations were carried out with the aim of separating unsteady eects from steady ones. As a result, o w unsteadiness turned out to have a positive impact on the sole lower radial gap conguration, especially in terms of the o w structure, in agreement with experimental indications. Moreover, physical mechanisms responsible for this behavior were identied and discussed.


The purpose of this study was to examine levels of physical activity and its correlation with neighborhood environment among children living in the 2011 Great Eastern Japan Earthquake and Tsunami affected area. A serial cross-sectional data set was developed for this study by conducting two surveys at approximately 1 year (N=209)and 4 years (N=142)after the occurrence of the earthquake and tsunami. At each survey point, assessment of physical activity for fourththrough sixth-grade schoolchildren was performed using a selfadministered questionnaire. The questionnaire also included questions on sex, age, grade, height, and weight. An independent t-test showed that the average sitting time on a weekday at the 4-year survey point was lower than that at the 1-year survey-point(t(296)=3.9, p<0.001, effect size(d)=0.22). Analysis using the quantification theory typeI revealed that neighborhood environment variables were not significantly associated with sitting time at the 4-year survey point. However, at the 1-year survey point, presence of sidewalks and residential density were significantly associated with sitting time on weekdays(b=−0.18, 95% confidence interval[CI]:−0.21 to−0.01, p=0.03)and sitting time on weekdays(b=−0.28, 95% CI:−0.27 to−0.08, p<0.001)and weekends (b=−0.20, 95% CI:−0.22 to−0.02, p=0.02), respectively. Moreover, a binary logistic analysis showed that high intensity physical activity such as exercise and sport, was not associated with the neighborhood environment variables at the 4-year survey point,whereas access to recreational facilities(odds ratio=2.74, 95% CI:1.24 to 6.02, p=0.01)significantly correlated with exercise and sports at the 1-year survey point. These results suggest that environmental restoration possibly improved physical activity among the children.

SYNOPSIS: The SEC has proposed a strategic plan that sets out its mission, vision, and values, four strategic goals, a set of desired outcomes associated with each strategic goal, and a list of performance measures for assessing the SEC's effectiveness in attaining its goals. We affirm the need for vigorous enforcement of securities law and offer some research-based insights and performance indicators. We also acknowledge the importance of disclosure, but propose that the SEC needs to develop a disclosure framework and develop better operational indicators of quality of disclosure. It is important to appreciate the benefits of disclosure as well as its limits and potential dysfunctional consequences. We also discuss the need for an independent accounting standard setter and recommend that the SEC take a greater role in enhancing the independence of the FASB.


The switched-capacitor realization of the discrete Fourier transform (DFT) is treated in this paper as well as the inverse discrete Fourier transform (1DFT). The output of the DFT has a sinusoidal waveform including the amplitude and phase information of the required spectra. These spectra are given simultaneously and almost in real time. The output of the 1DFT is given merely by adding DFT outputs. Furthermore, the circuit configuration of this system-from input to DFT, from DFT to 1DFT, and from 1DFT to output-is a very simple configuration constructed by a non-recursive filter circuit.


Magnonic crystals (MCs) are prototype magnetic metamaterials designed for the control of spin wave propagation. Conventional MCs are composed of single domain elements. If magnetization textures, such as domain walls (DWs), vortices, and skyrmions, are included in the building blocks of MCs, additional degrees of freedom over the control of the magnonic band structure can be achieved. We theoretically investigate the influence of DWs on the spin wave propagation and the corresponding magnonic band structure. It is found that the rotation of magnetization inside a DW introduces a geometric vector potential for the spin wave excitation. The corresponding Berry phase has quantized value <inline-formula> <tex-math notation="LaTeX">$4 n_{w} \pi $ </tex-math></inline-formula>, where <inline-formula> <tex-math notation="LaTeX">$n_{w}$ </tex-math></inline-formula> is the winding number of the DW. Due to the topological vector potential, the magnonic band structure of MCs with DWs as comprising elements differs significantly from an identical MC composed of only magnetic domains. This difference can be utilized to realize dynamic reconfiguration of magnonic band structure by a sole nucleation or annihilation of DWs in MCs.


I have appeared before the Section of Geodesy of the American Geophysical Union a number of times as a speaker on geodetic subjects. Today I shall cover a wider field, the field of mapping. Mapping is a fact-finding process. Without the facts furnished by maps, geophysicists, geodesists, geologists, and others have difficulty in planning and executing their operations.

Need for maps—This country is very poorly mapped. While 45 per cent of its area is covered by topographic maps, only about one-half of those maps are adequate for modern use. This means that about 75 per cent of our three million square miles have no topographic maps or have maps that are not serviceable. This is a situation that needs correction.


Telephone customers expect and usually obtain good quality service at any time under any condition. This high degree of availability is met even though any given telephone call involves numerous pieces of equipment. The major elements in a local call are the equipment at a customer's location, the wire pair connecting the customer to the local switching system, and the switching system itself. For toll calls, the local switch in a system is interconnected in a network of other switching and transmission systems. Failure anywhere in the physically distributed network can cause failure to originate a call, failure to complete the call to the called party, or unexpected cutoff.


Gas bag module for a motor vehicle having a housing (30), a connected to the housing gas generator (32) and a folded at rest in the housing gas bag envelope (10), wherein the airbag covering consists of fabric (20) in which mutually parallel substantially first threads (21) and each other substantially parallel second yarns (22) are woven together, said first and second yarns are substantially perpendicular to each other so that the fabric has a plurality of cross points between the first and second threads, the weaving of the first and second threads is not homogeneous and the inhomogeneity is generated by the fact that the fabric (26a, 26b) having areas in which at each crossing point of each first thread is separated from its adjacent first thread from a second thread, and vice versa, and that these regions through separating lines (25) in which first and second threads do not getre from each other at each crossing point are nnt, are at least partially separated from one another, characterized in that the ...

hymenal membrane. It is at this site that developmental abnormalities of the caudal reproductive tract are most frequently found. In other species, particularly the bitch, a number of embryological development abnormalities also occur at this site and cause narrowing of the tract, commonly termed stricture. In dogs such congenital strictures may be considered to have five aetiologies (Todoroff 1979, Holt and Sayle 1981, Wykes and Soderberg 1983, Soderberg 1986, Feldman and Nelson 1996). The first is the result of hypoplasia of the genital canal which causes vestibulovaginal hypoplasia and a vaginal stricture of some length. The second aetiology is the result of inadequate fusion of the Mullerian ducts with the urogenital sinus resulting in annular fibrous strictures at this site. The third condition relates to vestiges of mesodermal tissue remaining at the vestibulo-vaginal junction which form hymenal remnants or a complete hymen. The fourth aetiology is incomplete fusion of the two Mullerian ducts which may result in a double vagina or a vertical fibrous division within the vagina. Finally, imperfect joining of the genital folds and genital swellings can result in vestibulo-vulval hypoplasia. It is theoretically possible for strictures to develop as a result of trauma during coitus or parturition; these are extremely uncommon in the mare even following severe vaginal damage (Trotter 1993). Using the criteria above, it seems that the present case represents a combined type 1 and type 3 development abnormality. It is interesting to speculate why type 3 (hymenal) abnormalities are the most common in the mare and other abnormalities are so rare. It may be that fusion of the Mullerian ducts and the urogenital sinus is usually successful, but that abnormal mesodermal invasion of the urogenital portion of the hymenal membrane may occur with relative frequency. This would be similar to the condition observed in women (Muram 1993). Regardless of the exact aetiology of such abnormalities, if left undetected they could result in trauma to the mare and/or stallion at attempted coitus. The present cases emphasises the necessity of performing a careful pre-breeding soundness examination in mares.


The study of feasible tourism development in Klong-Toey slum is a part of city equality study. The main objective is to seek the best ways to improve tourism in Thailand's first slum at Klong-Toey District. The methodologies used for research are In-Depth Interview and Participant Observation. The study indicates that urban development influences the number of labor force in the agriculture sector of Thailand. Because of the Port Authority of Thailand construction in 1938, people from other provinces around Thailand have moved into Bangkok, seeking for a job in development and construction of infrastructure and settling their lives around the port area. Therefore, 41 communities with over 65,00 people have been living around the port. Klong-Toey is a congested community where social backgrounds and culture are its identities. All 41 communities are acting toward the aim of becoming a potential economic source, however, there are still many processes until it could successfully reach the position. One of the fastest and most effective ways for a country to improve Domestic Income is through tourism, both developing and promoting it. Tourism can be distinguished into different categories, for instance, Health Tourism, Agriculture Tourism, and Tourism of Designated Areas. Many countries have practically operated these tourisms, such as the Rainbow Village (Kampung Pelangi, the East of Jakarta, Indonesia), the City of Rio de Janeiro (Brazil), etc. In Rio Top Tour: Rio De Janeiro in the Different Perspective which encourages tourists to visit Favales or Mumbai City of India. In the case of Klong-Toey Slum, "Local Alike" agency has been making changes to the community. They found the possibilities that the slum could grow into a developed urban area. Therefore, they have been developing the area by renovating an abandoned area and introducing food and handicraft products, indicating local beliefs as the community's identity. They then operate a local tour within the community for tourists. Therefore, the study of Slum Tourism Development is aiming to develop slum and give new travel experience to tourists.

Enzyme motions facilitate many hydride-transfer reactions involving quantum mechanical (QM) tunneling. The evidence mainly comes from the determination of kinetic isotope effects (KIEs) and their temperature dependence that have been used to reveal interesting characteristics of human glycolate oxidase (HsGOX). Previous studies have shown that HsGOX oxidizes glycolate to glyoxylate via a hydride-transfer mechanism to an enzyme-associated FMN. Here, we investigate the temperature effect on the anaerobic rate of flavin reduction (kred) for HsGOX with glycolate and [2R-2H]glycolate. While the kred values for HsGOX are temperature-dependent, their KIEs on the kred values (Dkred) do not change as the temperature is varied. This is consistent with the involvement of QM hydride tunneling in the highly optimized active site of HsGOX. We show that the enzyme motions are slaved by the fluctuations in the bulk solvent after determining the kred and Dkred for HsGOX at various solvent viscosities and constant temperat...


An active learning class exercise is presented that gives students the personal experience of the decision-making limitations of mental models. This innovative exercise was shown to increase student learning through greater understanding of the concept and higher retention of knowledge. The results suggest that student critical thinking skills were enhanced by the awareness of their own vulnerabilities to mental models in decision making.

We present data on sample richness, relative abundance, and community structure of a leaf litter amphibian assemblage from globally important miombo‐mopane woodlands characteristic of western Tanzania. We describe patterns of diversity across major habitat types and between different seasons from an annual pitfall‐trapping campaign. We recorded 28 species of amphibians, which is significantly higher than existing richness estimates for other miombo woodland sites elsewhere in sub‐Saharan Africa. We found that cultivation of native habitat reduces frog diversity, a conclusion that has important implications in light of the rapid conversion of miombo woodland for agriculture and fuel‐wood across much of southern and central Africa. Many species showed strongly ansynchronized patterns of seasonality in relative abundance, which has significant implications for the establishment of successful monitoring programs and biodiversity surveys. These conclusions emphasize the importance of stratified long‐term sampling in biodiversity studies and demonstrate that superficial levels of sampling effort can lead to erroneous conclusions regarding patterns of diversity in amphibian communities. The relatively poor focus on herpetofaunal research in African miombo‐mopane woodland is out of proportion to its ecological and conservation significance.


Fauna of nematodes damaging mainly vegetables and ornamental plants in some areas of Chiba Prefecture which is situated in the northern part of the temperate region of Japan was investigated. Root-knot nematodes (Meloidogyne spp.) were detected in 18 fields among 29 fields of vegetables and ornamental plants and M. incognita and M. javanica were observed on carnation planted in green houses at Tomiura. A spiral nematode (Helicotylenchus dihystera) was isolated from 50% of the cucumber fields while reniformis nematode (Rotylenchulus reniformis) was detected in only one field each of garden pea and amaryllis. Root-lesion nematodes (Pratylenchus spp.) were detected in flower, strawberry and potato fields in a limited area, at a high density, while pin nematodes (Paratylenchus spp.) were detected frequently on various crops at a low density. Fauna of nematodes damaging crops in some areas of Chiba Prefecture was different from that in Shizuoka and Kagawa Prefectures since ring nematodes (Criconemella spp.) and stylet nematodes (Tylenchorhynchus spp.) could not be detected while R. reniformis was infrequently observed though a large population of Meloidogyne spp. occurred commonly in both areas. The nematode fauna also differed from that on Ishigaki Isl. since in Chiba Prefecture Meloidogyne spp. were detected at a high frequency and H. dihystera and R. reniformis at a low frequency while Tylenchorhynchus spp., Hoplolaimus sp. and Paratrophulus sp. were not observed.

In modern society, Time is developing into a dominant force, with time anxiety, time poverty, and time tyranny becoming increasingly prevalent. The Genuine Human's "yizhi weishi" (以知为时, to take Understanding as composed of time), the concept of time found in the Zhuangzi, emphasizes the overall perception and active construction of characteristics of time, and offers the possibility of enhancing a proactive understanding of time. In the Zhuangzi's perspective, time is not only continuous, infinite, and one-dimensionally linear, but also intermittent, finite, and cyclical. "Yizhi weishi" is intended to grasp these characteristics of time, to actively use and participate in the construction of time, which is the method of the "Genuine Human" for mastering time. For modern society, the "yizhi weishi" perspective of time enlightens people to harmonize their socially ordered time with the rhythms of nature, to reconstruct the vast connection between human beings and cosmic space with a contextualized concept of time, and to manage time from the perspective of "internal dynamics" rather than "external limitations". Such a perspective has important inspirational value for enhancing the quality of human life and improving the order of human production and existence.


The three-year project on building a VGOS radio telescope system at the Metsahovi Geodetic Research Station, Finland, is advancing as planned. The installation site was ready for the
telescope arrival with the foundation and the anchor ring for the antenna's steel pedestal already on site by the end of 2017. The manufacturing of the telescope was completed by MT Mechatronics GmbH and it was delivered on-site in June 2018. Telescope assembly and installation was performed during the summer and finalized in October 2018. The assembly of the signal chain components also moved forward. The installation and integration of the signal chain is scheduled for the spring
2019, and it is expected to have first observational tests by the end of 2019. This paper presents the latest project status and describe the next steps for the Metsahovi VGOS station.


The authors describe designs of hohlraums and capsules for both ignition ({approximately}1--10 MJ) and high yield (up to {approximately}200 MJ) Z-pinch driven indirect-drive ICF concepts. Two potential Z-pinch hohlraum configurations: (1) the static wall or on-axis hohlraum; and (2) the imploding liner or dynamic hohlraum are considered. Both concepts involve cryogenic, DT-filled capsules ({approximately}2--4 mm in diameter) with Be or CH ablators (O, F, and Cu are currently being considered as dopants). Both types of hohlraums involve a Helium and/or CH foam fill. In the static wall hohlraum concept, the ICF capsule is isolated from the x-ray generation region. Advantages in the areas of capsule drive symmetry and diagnostic access might be gained from this arrangement. In the dynamic hohlraum, the ICF capsule has a direct view of the stagnation radiation. The potential advantage would result from the higher x-ray intensity and larger total capsule absorbed energy.


AbstractThis study describes a simple, inexpensive and sensitive extraction procedure using γ-Al2O3 nanoparticles modified with sodiumdodecylsulfate, as an efficient solid phase, for removal, preconcentration and spectrophotometric determination of trace amounts of malachite green (MG) by fiber optic-linear array detection spectrophotometry. The properties of the produced modified nanoparticles were determined by FESEM and TEM. Various effective parameters on the preconcentration of MG, such as pH, sample volume, amount of sorbent, type, concentration, contact time, temperature, and volume of eluent were investigated. Under the optimized operating conditions, the calibration graph was linear over the range of 1.2–250 μg L−1 and relative standard deviation of 1.50% at 100 μg L−1 were obtained (n = 5). The limit of detection (S/N = 3) was obtained 0.34 μg L−1. The Langmuir adsorption capacity (qmax) was found to be 72.4 mg g−1 of the adsorbent. The method has been successfully used to determine of MG in fish...

The detailed proof of cancellation of topologically unfactorized infrared divergences in the inclusive production of lepton pair close to the threshold of heavy quarkonia is presented. To make the effects of transition between states containing heavy quark pairs, which is important in such cancellation, the final detected states are constrained to be lepton pair near the threshold of the heavy quarkonia instead of heavy quarkonia themselves. Such cancellation is crucial for the NRQCD factorization of these processes.


The paper summarizes our data regarding the energy controlling of the transonic flow. The criterial analysis of the regimes of flow which is formed around the airfoils with an external pulse-periodic energy supply was performed. We selected four criteria, which belong to the class of criteria homochronicity. They are determined by the relations between the period of the energy supply, the rate of gas flow, the velocity of propagation of small disturbances and distances from the beginning or the end zone of energy supply to the position of the closing shock in the undisturbed flow, or the size of the zone of energy. It was shown that the conditions for the forming of the nonlinear regime can be described in terms of the entered criteria of homochronicity. We also obtained estimates for the minimum energy at which the effect of nonlinear interaction is possible, as well as the time of formation of the periodic mode. It was found that the nonlinear effect predominantly has gas-dynamic nature. It was shown that the results of numerical modeling are in agreement with the criterial estimates


In this paper we compare visual and textual programming languages for generative design. We argue that, in the past, this comparison has been flawed and that it is now time to reconsider the potential of the textual programming paradigm but using modern programming languages and development environments specifically targeted to the generative design domain. We present VisualScheme as a prime example of such language and we compare it with the most used visual programming language in the generative design field.


When the consequences of a response become less reinforcing in the presence of one stimulus, reinforced responding in the presence of a second stimulus often increases. This phenomenon is called positive behavioral contrast. This research evaluated the effects of an analogous manipulation in an applied setting within the context of a classroom token economy. Seven severely to profoundly hearing impaired middle school students who were disruptive and low-achieving in math class served as subjects. After a pretoken economy baseline, token reinforcement was instituted at three learning stations. Reinforcement was then withdrawn from two of the three stations but continued at the remaining one. The results indicated that academic response rate increased at the station where reinforcement was continued while it decreased at the two stations where it was withdrawn. These effects were reversed when reinforcement was reinstated at all three stations. The reciprocal relationship between increases in academic performance and decreases in measures of classroom disruption previously reported in the literature was also replicated.


Some formal models for pattern-sensitive faults (PSF's) in random-access memories are presented. The problem of detecting unrestricted PSF's is that of constructing a checking sequence for the memory. An efficient procedure for constructing such a checking sequence is presented. A local PSF is defined as a PSF where the faulty behavior of a memory cell Cidepends on a fixed group of cells called the neighborhood of Ci. Neighborhoods are divided into two classes, open and closed. Test generation methods are described for local PSF's defined on both open and closed neighborhoods. The detection of PSF's when only one memory cell is faulty (single PSF's) is also discussed.


Chaluhe area of Yitong Basin has been explorated several times. But all explorations have not make an substantive breakthrough yet. Based on the collected data of hydrocarbon source rocks of Chaluhe area, systematic sampling, we conducted a sampling system. Samples were analyzed for TOC, "A", S1 + S2 and other indicators to evaluate the organic matter abundance. The results show that the dark mudstone most develops in shuangyang group in middle shallow layer of Chaluhe area, where has high abundance of organic matter and can be an effective source rock. Complex the above analysis, we predict for favorable exploration area and laid the foundation for further exploration to deploy Chaluhe region.


Methods to continuously forecast water levels at a site along a river are generally model based. Physical processes influencing occurrence of a river stage are, however, highly complex and uncertain, which makes it difficult to capture them in some form of deterministic or statistical model. Neural networks provide model-free solutions, and hence can be expected to be appropriate in these conditions. Built-in dynamism in forecasting, data-error tolerance, and lack of requirements of any exogenous input are additional attractive features of neural networks. This paper highlights their use in real-time forecasting of water levels at a given site continuously throughout the year based on the same levels at some upstream gauging station and/or using the stage time history recorded at the same site. The network is trained by using three algorithms, namely, error back propagation, cascade correlation, and conjugate gradient. The training results are compared with each other. The network is verified with untrained data.


AbstractThe paper examines whether changes in technology have substantially altered the economic case for regarding the Hydrographic Survey Services as public goods to be provided as a public service. After a survey of the manner in which technology has altered the working practices of Hydrographic Survey Service, it concludes that there has been no major change in the economic rationale for regarding it as a public good.


A series of novel Pt-modified Cu–Fe–La/γ-Al2O3 catalysts were prepared by an incipient-wetness impregnation method, and their performances were evaluated in catalytic wet air oxidation (CWAO) of printing and dyeing wastewater (PDW). The as-prepared catalysts were characterized by X-ray photoelectron spectroscopy (XPS), nitrogen adsorption–desorption, X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), Raman spectroscopy, and temperature programmed reduction by hydrogen (H2-TPR). The effects of catalyst composition and calcination temperature on the catalytic performance were investigated. The chemical oxygen demand (COD) removal efficiency and decolorization rate are satisfactory over Cu1.5Fe1.5La3/γ-Al2O3 catalyst, with poor stability under CWAO conditions. In contrast, catalytic performance and stability of all Pt-modified catalysts are significantly improved. With increasing calcination temperatures from 350 °C to 750 °C, the activity of the catalysts significantly decreases from 97.3% to 84.6%, and the size of the particles varies from 4.71–6.95 nm. The XRD, HRTEM, and XPS results indicate that the Pt1Cu1Fe1La3/γ-Al2O3 catalyst mostly comprises Pt, CuO, Fe3O4, and La2O3, and the incorporation of Pt increases the binding energies (BEs) of the metal elements in the catalyst, owing to synergistic interactions between the Pt and the Cu, Fe, and La elements. After five cycles, the COD removal efficiency and decolorization rate for PDW over the Pt1Cu1Fe1La3/γ-Al2O3 catalyst calcined at 650 °C remain comparable with the fresh catalyst, indicating that Pt-modified Cu–Fe–La/γ-Al2O3 ternary oxide is a promising catalyst with high activity and stability for CWAO treatment.


Short circuit current analysis and calculation is the key technology of DC distribution system design. Taking the pure battery powered ship as the analysis object, this paper analyzes and calculates the short-circuit current of DC distribution system, which has a good reference value for the research of pure battery powered ship design technology.


Fleet assignment consists of deciding on the type of aircraft that will operate on each specific flight. The objective of this scheduling stage is to minimize total cost or maximize total profit. The inherent complexity of the fleet assignment problem normally has resulted in the development of an integer programming based model or various heuristic solution procedures. In this research we use the Max-Min ant system (MMAS), one of the ant colony optimization heuristic methods (ACO), to solve a large scale weekly fleet assignment model in which variable departure times are considered. By adjusting new departure times, this model provides more schedule flexibility. This thesis also provides some experimental results in order to compare the ant colony optimization method with one exact solution method, "branch and cut". Using data from real major airlines, the result from the implementation shows that the proposed MMAS approach not only can solve an airline fleet assignment problem with less than 5% error from an exact solution method but also can extend to simultaneously solving fleet assignment problems along with aircraft routing problems.


BRAIN membranes are rich in sialoglycoproteins (BRUNNGRABER et al., 1967; GOMBOS et al., 1971). A rational approach to the role of these macromolecules in interneuronal and neuronal-glial recognition requires precise information on their metabolism and on the possible modifications they undergo within the membrane. Release of neuraminic acid is especially important. In previous short-term experiments on different animals we were unable to demonstrate a considerable release of protein bound NANA (PF~ETI et al., 1970; TETTAMANTI et al., 1972~) by the action of brain neuraminidase on endogenous particulate sialoderivatives. These reports suggested that brain membrane bound sialoglycoproteins are resistant to endogenous neuraminidase. However, in 1972 HELILMAN and ROUKEMA provided definite evidence that N-acetyl neuraminic acid could be released from endogenous sialoglycoproteins of calf brain homogenate, indicating that the particulate sialoglycoproteins should also be affected by neurarninidase. We therefore decided to ascertain to what extent brain membrane bound sialoglycoproteins are affected by membrane bound neuraminidase (EC 3.2.1 3).


The utilization of abundantly available animal feed grade wheat (AFW) as a replacement for conventional and costly cereal supplement in lamb feeding to lower the cost of mutton production was explored. Thirty-five growing lambs divided into five equal groups and were fed diets containing 0, 118, 235, 353 or 470 g kg−1 AFW replacing equal quantity of maize. The diets were fed in the form of composite feed mixture, which had a roughage (Prosopis cineraria leaves) to concentrate ratio of 25:75. Dry matter intake (DMI) was not different in these groups, ranging from 35 to 42 g kg−1 body weight, while AFW inclusion linearly (P < 0.05) reduced DMI. The digestibility coefficients of dry matter (DM), organic matter (OM), crude protein (CP) and cellulose were not affected by AFW addition, whereas neutral detergent fibre and acid detergent fibre digestibility coefficients were reduced (P < 0.05). The digestible CP content (142.7–162.7 g kg−1 diet) increased (P < 0.01) linearly with increased AFW inclusion levels. However, AFW additions did not affect metabolizable energy (ME) value of diet (10.2–10.5 MJ kg−1 diet DM). Digestible CP intake was similar but digestible DM and OM intake tended to decrease (P < 0.05) linearly when expressed in terms of g kg−1 W0.75. ME intake (MJ d−1) was not different among the diets but showed linear (P = 0.041) reducing trends with increasing AFW levels in diet. The efficiency of ME and N utilization for unit gain was also not affected by AFW incorporation. N retained as g d−1, percentage of intake and percentage of absorbed ranged from 15.4 to 19.5 g, 49.7% to 60.3% and 62.6% to 74.6%, respectively. Intake and utilization of dietary N was not affected but urinary N excretion reduced (P < 0.05) linearly by AFW. Daily microbial N (MN) flow estimated by urinary purine derivative excretion was significantly (P < 0.01) higher for lambs fed a diet with AFW 235 g kg−1 (3.05 g MN) and 353 g kg−1 (2.51 g MN) compared to without AFW diet (1.31 g MN). MN when expressed as g kg−1digestible organic matter intake (DOMI) and microbial protein g kg−1 digestible organic matter apparently fermented in rumen (DOMR) followed a similar trend. During the growth trial, lambs fed diets containing AFW (353 g kg−1), which replaced 75% maize had higher total gain (14 kg, P < 0.05) and average daily gain (ADG 154 g, P < 0.05). However, feed efficiency (feed consumed kg−1 live weight gain) was not different. Rumen pH and microbial enzyme activities studied 4 h post feeding revealed that AFW did not affect rumen pH, which ranged from 5.95 to 6.30. Similarly, carboxymethyl cellulase and β-xylosidase enzyme activities were not different among treatments, but AFW inclusion linearly (P = 003) increased carboxymethyl cellulase enzyme activities. The α-amylase enzyme activity differed significantly (P < 0.05) and was highest (22.6 IU) in groups where AFW replaced maize completely. It was concluded that, in lambs reared under intensive system for mutton production on high concentrate diets, conventional and costly energy supplements like maize can be replaced up to 75% with a low-cost animal feed grade wheat to economize on cost of production. However, more studies are required to confirm these inclusion levels for greater economic returns. Copyright © 2007 Society of Chemical Industry


This paper presents an innovative calorimetric method for measurements of AC losses of high-temperature superconducting (HTS) tapes by using effect of optical fiber Bragg grating (FBG) wavelength shift resulting from temperature change caused by AC losses, where it is adopted as temperature sensor. The HTS specimen on which the FBG are attached on are adiabatically processed before measuring. Comparing with conventional electric and calorimetric methods, FBG temperature sensor has advantage of rapid response and anti-electromagnetic interference due to its thin geometrical sizes and optical characteristics, it is thus very suitable to AC loss measurement of HTS applications in much more complicated electromagnetic circumstance. By measuring the effect of temperature on wavelength shift in low temperature range, it is indicated that FBG has good enough repeatability of dependence of wavelength shift on temperature measurement around liquid nitrogen temperature of 77 K. After calibration, AC loss of BSCCO HTS tape in self-field is measured by the FBG sensor, and the measured loss is also measured by conventional electric method using lock-in amplifier (LIA). It is shown that the measured AC loss is agreement with the results measured by electric method and those based on Norris theory, so that the presented calorimetric method is available for measuring the AC loss of superconductors and expected to be generalized to AC loss or thermal measurements of other bulk superconductors.


A broad bandwidth analog fiber optic link is developed for ultra-fast signal transmission under the circumstance with complicated electromagnetic fields. The electrical ultra-fast signal is converted to optical ones by electro-optic conversion method which operates via amplitude modulation mechanism. With several kilometers distance transmission, the optical signal is recovered by photo-electric conversion method correspondingly. The measurement results of the link indicate that its bandwidth is (0.0003-3)GHz, in-band flatness ±1dB, linear dynamic range 40dB, output peak-to-peak noise within 5mV, both of input and output standing-wave-ratios less than 2. It's applied in high power microwave experiments. The experimental results show that the 3GHz analog fiber optic link which employs electro-optic and photo-electric conversion techniques is suitable for ultra-fast pulse signals transmission. It greatly improves the bandwidth margin of the diagnosis system.


Aims: In this study we aimed to analyze gender health equity as a case of how social policy contributes to population health. We analyzed three sets of social-investment policies implemented in Europe and previously hypothesized to reduce gender inequity in labor market outcomes: childcare; active labor market programs; and long-term care. Methods: We use 12 indicators of social-investment policies from the OECD Social Expenditure Database, the OECD Family Database, and the Social Policy Indicators' Parental Leave Benefit Dataset. We draw outcome data from the 2015 Global Burden of Disease for years lived with disability and all-cause mortality among men and women ages 25–54 for 18 European nations over the 1995–2010 period. We estimate 12 linear regression models each for mortality and morbidity (i.e. years lived with disability), one per social-investment indicator. All models use country fixed-effects and cluster-robust standard errors. Results: For years lived with disability, women benefit more from social investment for most indicators. The only exception is the percentage of young children in publicly funded childcare or schooling, which equally benefits men. For all-cause mortality, men benefit more or equally from social investment for most indicators, while women benefit more from government spending on direct job creation through civil employment. Conclusions: Social policy contributes to the distribution of population health. Social-investment advocates argue such policies in particular enhance economic gender equity. Our results show that these polices have ambiguous effects on gender health equity and even differential improvements among men for some outcomes.


It is well known that the dynamic performance of a rocket or launch vehicle is enhanced when the length of the divergent section of its nozzle is reduced or the nozzle exit area ratio is increased. However, there exists a significant performance trade-off in such rocket nozzle designs due to the presence of random side loads under overexpanded nozzle operating conditions. Flow separation and the associated side-load phenomena have been extensively investigated over the past five decades; however, not much has been reported on the effect of side loads on the attitude dynamics of rocket or launch vehicle. This paper presents a quantitative investigation on the influence of in-nozzle random side loads on the attitude dynamics of a launch vehicle. The attitude dynamics of launch vehicle motion is captured using variable-mass control-volume formulation on a cylindrical rigid sounding rocket model. A novel physics-based stochastic model of nozzle side-load force is developed and embedded in the rigid-body model...


According to the relevant IEC standards, the back-to-back capacitor banks switching tests need to withstand an inrush current of 20 kA (peak) with 4250 Hz frequency. For vacuum interrupters (VIs), the contact surfaces may be seriously damaged by the high inrush current. The objective of this paper is to investigate how the inrush current influences the field emission current of VIs under power-frequency voltage. The amplitudes of the inrush current were set as 10 and 20 kA. The samples VIs suffered the inrush current of different amplitudes twice consecutively. Then, the field emission current of VIs was measured by applying a power frequency voltage upon the contact gap of 1 mm. The experimental results show that the field emission current is unsymmetrical in contrast with the power frequency voltage's polarity. There is a critical voltage value that the applied voltage exceeds it can make the field emission current increase significantly. Besides, the more times of imposing inrush current on the contacts and higher inrush current will lead to a higher field emission current.


Relative to many investigations of inertial gravity waves (IGWs) in the Antarctic, IGW activity in the Arctic region was paid less attention to. We use radiosonde observations at the Ny‐Alesund station (78.9°N, 11.9°E) from April 2012 to June 2016 to study the IGW characteristics in the lower stratosphere over the Arctic. The observation reveals a prevailing eastward zonal background wind below 20 km and an obvious annual cycle of the background temperature from the troposphere to the lower stratosphere, which is different from the results in the middle and low latitudes. By combining Lomb‐Scargle spectrum and hodograph technique, case study demonstrates that the lower stratospheric IGWs exhibit a feature of freely propagating waves. Statistical analysis indicates that the IGWs have dominant horizontal (vertical) wavelength of 50–1,050 km (1–4 km) and ratio (1–2.5) of the intrinsic to inertia frequencies. Wave energy exhibits an annual oscillation with the maximum in winter and the minimum in summer. In winter, the downward propagating waves increase to about 20% due to polar stratospheric vortex. Because of the lower atmospheric filtering, the IGWs display a dominant direction of westward propagation, thus have a mean vertical flux of −0.647 mPa for the zonal momentum, which indicates that the IGWs can put a westward drag on the atmospheric wind field over the Arctic as they break and dissipate. All the vertical wavenumber spectra have spectral slopes from −2.23 to −2.99 close to the universal spectrum index of −3.


In this paper we address a class of problems consisting of highly structured computations on data sets that are described by hierarchical data structures. These are often represented as tree structures to optimize data storage requirements and perform e cient queries for data access. Speci cally, applications that are dynamic and perform many iterations on data are of interest to us, since the requirements for data evolve over time and require modifying data structures incrementally. The computational relationship between the subdomains is known only at runtime, and may change between computation phases. Parallelization of such applications requires e cient distributed data management and has received some attention recently. We study the computational structure of a few irregular applications falling in this category. This helps us to discuss the needs of choosing an appropriate data structure and the issues of data partitioning, load balancing and communication requirements for these applications. Most recent e orts have been application speci c and solutions are not portable across applications or parallel computing platforms. We wish to characterize requirements for primitives and runtime software support needed to parallelize irregular applications. In this paper we present a detailed study of the computational structure of the following eight hierarchical applications: N-body simulation, Molecular Dynamics, Hierarchical Radiosity, Volume Rendering and Ray Tracing, Spatial databases, Adaptive meshes and, Image Compression. This allows us to identify requirements for parallelization across a broad spectrum of applications. Each of these applications uses a tree data structure. We enumerate tree algorithms that are used for solving these applications and discuss their parallelization. Next, we present an outline of common primitives that are required for these applications. Requirements for a runtime support system are presented for obtaining e ective parallel solutions using the above primitives on coarse-grained distributed memory machines.


This paper presents a detailed idea about the face detection technique which reduces false positive rate and improves the rate of detection. Face detection remains as one of the challenging problems in the field of image analysis and computer vision. The color image is converted into a grayscale image. Based on the spatial localities and orientation characteristics of the Gabor filter, we extract the facial feature from the facial image by appropriate filter design. The input of feed-forward neural network classifier is the feature vector obtained by the Gabor filter. The convolution is done by multiplying the image with the Gabor filter in the frequency domain and is saved in a cell array in order to save time. Thus the input of the network will have larger values and is optimized by reducing the matrix size to one-third by deleting appropriate number of rows and columns. The results obtained in the output layer in testing with real-life images shows that the false-positive rate is reduced by 97%.


Introduction The electronic states of ruthenium(II) complexes with diimine ligands are widely investigated in relation to their good performance as the light sensitizer for the reductive catalysis system and the tris(2,2'-bipyridine)ruthenium(II) complex ([Ru(bpy)3] ) has been a recent subject of the time-resolved X-ray absorption spectroscopy [1]. In this study, the time-resolved XAFS measurements in the order of ns have been carried out using a single-bunch property of PF-AR to investigate not only the electronic state but also the local structure around the Ru center.


AbstrcatAccording to Fisher discriminant criterion,a new method whose discriminant coefficient and critical value change along with time was put forward and applied to forecast precipitation in July of the Zhengyuan observational station whose rainfall can mostly reflect the changing rule in Longitudinal Range-Gorge Region.Based on the former researches that pointed out Indian Ocean temperature distinctly influenced on the precipitation change over the region,a discriminant predictive equations were built with the former autumn,winter and spring zonal gradient of sea surface temperature anomalous.The application results indicated that the new method had efficient fitting and forecasting accuracy as well as better forecasting stability.


At Bruckner's times, the intonation in the orchestr a was quite different – not the muddy adoption of t he ›compromised‹ intonation of the modern piano, but l argely a pure intonation (fifths and thirds), as it was available in Berlin, due to the influence of Joseph Joachim and his pupils, almost until ca 1940. Only the pure, ›naturally harmonic‹ intonation would bring a ll the colours of Bruckner's harmony, so full of enharmonics and chromaticism. The fabric of contemp orary woodwind instruments tests the case: Before 1900 – as, for instance, preserved in collections i n Vienna – they had keyholes bored in a different intonation. For this reason, ourday's contemporary orchestras which still use those old instruments ac hieve better results in Bruckner (such as the Orchestra of the Age of Enlightenment or the Orchestre des ChampsElysées ), because even modern-trained string players autom atically adopt their playing to what they hear from the woodwind and brass. On the opposite, moder n woodwind and brass instruments have our typical ›compromised‹ intonation; this, together with some peculiar bad habits of string intonation routine, l ike sharpening sharps and flatening flats, brings bad r esults for Bruckner – there should be an audible di ff rence between, let's say, F sharp or G flat major. The co nductor should at least be aware of such shortcomin gs. The knowledge on contemporary instruments may already a nswer important questions regarding the balance. Th brass instruments were at about a third smaller, an d at about half as loud as today. The large F-Trump et, handmade Horns and Trombones of that time produce a much more pungent, full, and rich sound, even if n ot so horribly powerful like ourday's batteries. Also w odwind instruments were much more colourful those days. With modern, large brass instruments, the con ductor should in any case always double woodwind instruments to improve the balance, and care for at least 8 Basses, 8 Celli, and 10 Violas. For Bruckn er's four-part-writing of harmony, it is essential to ma ke audible particularly the inner voices, Alto and Tenor. (The outer parts are audible anyway!) The brass sho uld never outpower the woodwind. Not ourday's monstrous Horns and Trombones, of which one only ca n destroy an entire orchestral balance, but the woodwinds should dominate the wind sound even in th e loudest fortissimo!


This journal will discuss fun parenting during a pandemic. This journal aims to describe how parenting patterns are used during the COVID-19 pandemic, so as to create healthy behavior in children, both physically and mentally, even during the Covid-19 disaster. The method used in writing this article is to use a literature review. The results of this article indicate that a fun parenting pattern during the Covid-19 pandemic must prioritize authoritative parenting. This is because during the Covid-19 pandemic, parents have an extra role to play in assisting children to learn online. In this case, of course, parents are required to have appropriate and pleasant parenting in accompanying children while at home. Good behavior emerges from good parenting, and vice versa.


The grid-connected LCL-filtered inverter is widely used in distributed power generation systems based on renewable energies. Single inverter-side current feedback control only needs to sample one current to realize both current control and inverter protection. However, with single inverter-side current feedback control, the closed-loop system is under-damped or even unstable due to the digital control delay. In this paper, an active damping control based on only inverter-side current feedback is proposed. With the novel control, the resonance in the digitally-controlled LCL-filtered inverter is successfully solved while only inverter-side current is sampled. Comparisons of the proposed and typical single inverter-side current feedback control have verified the improvement of the proposed control. Thus, the proposed control has good application prospect in grid-connected LCL-filtered inverters.


Although the maternal mortality rate in delivery has been reduced dramatically in recent years, hemorrhage remains one of the main causes of mortality in Japan. Therefore, how to promote blood donation and how to provide a sufficient supply of blood are very important as well as essential matters in obstetrical practice. From these reasons, a campaign named "Kohnotori Blood Donation" has been driven since May, 1984 in Aomori prefecture.The system promoted is that family members of a pregnant woman donate their blood prior to her delivery. The number of "Kohnotori" donors has been increasing: there were 985 donors in 1984 and 1427 in 1985. Promotion of blood donations by clinicians may also contribute to saving and proper use of blood products.


The effect of external ATP on intracellular pH (pHi) was investigated using a pH imaging system in a human bronchial epithelial cell line (16HBE14o‐) loaded with BCECF‐AM. The steady‐state pHi of 16HBE14o‐ epithelial monolayers was 7.137 ± 0.027 (n= 46). Apical addition of ATP (10−4m) to epithelial monolayers induced a rapid and sustained pHi decrease of 0.164 ± 0.024 pH units (n= 17; P < 0.001). The intracellular acidification was rapidly reversed upon removal of external ATP. In contrast, the non‐hydrolysable ATP analogue AMP‐PNP did not produce any significant change in pHi. Inhibition of purinoreceptors by suramin did not affect the acidification induced by apical ATP. Inhibition of Na+‐H+ exchange by apical Na+ removal or addition of amiloride (0.5 mm) reduced the apical ATP‐induced pHi decrease, suggesting the involvement of a Na+‐H+ exchanger or surface pH effects on the ATP‐induced pHi response. Inhibitors of proton channels such as ZnCl2 (10−4m) also partially inhibited the ATP response. The pHi response to ATP was dependent on the external pH (pHo), with increasing acidification produced at lower pHo values. Neither the basal pHi nor the ATP‐induced intracellular acidification was affected by thapsigargin (a Ca2+‐ATPase inhibitor), chelerythrine chloride (a protein kinase C (PKC) inhibitor), RpcAMP (a protein kinase A (PKA) inhibitor) or PMA (a PKC activator). Therefore, the intracellular acidification of human bronchial epithelial cells induced by apical ATP does not involve signalling via Ca2+, PKC or PKA nor binding to a purinoreceptor. We interpret the effect of ATP to produce an intracellular acidification as a three step process: activation of H+ channels, inhibition of Na+‐H+ exchange and influx of protonated ATP.


Almost all of the meteorological elements have influence on the success of the agricultural cultivation, but in Hungary among all of these elements precipitation is the most capricious one. The aim of our research is to detect the changes in the 130-year-long time series of precipitation. The precipitation at Keszthely shows a not significant decreasing trend of 42 mm less rainfall in a 100 year long period. The seasonal amounts of rainfall -except for winter- are decreasing. The significantly reduced amount of spring is an unfavorable factor for agriculture. The usual secondary maximum of the yearly precipitation in the autumn at Keszthely seems to vanish. Our farmers must count on at least one period of more than 15 days without rainfall, or two dry periods of 10-14 days length in a vegetation period.


Mobile technologies have become a crucial functional element of modern organizations. They provide uninterrupted access to information, regardless of the user's geographic location and time. Customer service, quality, satisfaction and retention are key proponents of measuring success and profitability in any organization. Due to the exponential growth of information technology, banks face dual competitive pressures to provide service quality and administrative efficiency. Accordingly, banks need to retain their existing users of mobile banking (m-banking) services to be able to benefit long term from this sustained usage behavior. The problem for banks is that the current understanding of determinants of m-banking sustained usage is limited. We propose some modifications to the DeLone and McLean Model (2003) of Information Systems Success in light of descriptive and relational studies, whereby the universal model may be applicable in post adoption user retention context. Using the findings of the review of theories and models, banks in Saudi Arabia can improve their m-banking strategies to achieve higher retention rates of existing users of m-banking services. While this study focused on m-banking user retention in the Saudi Arabian context catering to post adoption scenario, the purpose of this study is also to establish a universal measurement model for post adoption user perception of m-banking services, with global applicability.


BACKGROUND
 Digital health is an important part of the future of health care, prevention and management of disease and innovative monitoring solutions. With an aging population and rising health related costs, digital health is an essential part of the solution, alongside the emerging big data and associated analytics. To varying extents, digital health and big data are present worldwide. However, consistency in terminology, regulation and implementation differ. As an international network of interdisciplinary experts we review and discuss the digital health and big data landscape.

 OBJECTIVE
 We firstly identify current challenges and solutions in digital health development, research, deployment in the management of non-communicable disease and regulation and then go on to establish an ongoing and international collaboration of multidisciplinary researchers and educators; creating opportunities for research and education.

 METHODS
 The Digital Health Research Network was established using the Worldwide Universities Network as a platform and a funding resource. The newly formed network harnesses expertise from a wide array of academic disciplines within applications of digital health and big data for health.
Meetings took place both electronically and face to face, with a Research Open Day in Sydney and the International Symposium for Digital Health in Hong Kong facilitating wider networking and discussion.

 RESULTS
 Many challenges working across disciplines in the digital health area have been identified. These include inconsistent definitions for digital health and big data, a diverse range of digital technologies available across the globe, differences in regulation of such technologies. There is not equity in resources and standards globally. He range of stakeholders involved in digital health and big data relating to health are extensive. It is important that these stakeholders can communicate effectively, with a common technical language. Continued development, education and widening engagement are integral components of developing digital health worldwide.

 CONCLUSIONS
 Digital Health is a necessary and sufficient factor in achieving health gains. However, in is critical that digital health is leveraged appropriately and that transformation of interdisciplinary practices can intelligently link digital health with care management processes to make a difference. The new interdisciplinary, International Society for Digital Health aims to provide a platform to facilitate this.

This article examines the key factors shaping the opportunities for feminist journalism in large, mainstream media organizations. It shows how journalists' notions about gender, different professional journalistic ideals, and feminist media activism advance or hinder feminist journalism at different levels of media production. The impact of these factors is explored further in the particular contexts of the post-authoritarian societies of contemporary Serbia and Croatia. While individual Serbian and Croatian pro-feminist journalists were often able to pursue socially committed journalism in their day-to-day choice of topics, sources and approaches, their opportunities to affect programme, departmental or channel policy were more limited. Such opportunities depended on a constellation of the following factors: the strength of women's non-governmental organizations' media activism; media management's support for gender equality initiatives and/or critical forms of journalism; and the broader political developments concerning gender and media politics in the two countries.


Using steady-shear rheometry in combination with high-pressure 11B nuclear magnetic resonance spectroscopy (11B NMR), we have found that gels formed from water-soluble polymers containing vicinal hydroxyl groups cross-linked with various boron-containing compounds undergo significant structural changes that result in a pronounced loss of viscosity when placed under pressure. Importantly, gels from other cross-linking agents tested, including Ti(IV) and Zr(IV), did not show this loss in viscosity. The experimental study probed pressure-induced changes to both galactomannan and polyvinyl alcohol (PVA) gels cross-linked with either aryl boronic acids or alkali metal boron-containing salts using pressure conditions that ranged from atmospheric to 680 bar and temperatures that ranged from 20 to 65 °C. Significantly, the pressure-induced losses in viscosity and, to a somewhat lesser extent, the concomitant pressure-induced 11B NMR spectral changes were found to be reversed upon lowering the pressure.


Social responsibilities of businesses and their managers have been discussed since the 1950s. Yet no consensus about progress has been achieved in the corporate social responsibility/corporate social performance literature. In this article, we seek to analyze three views on this literature. One view is that development occurred from conceptual vagueness, through clarification of central constructs and their relationships, to the testing of theory—a process supported by increased sophistication in research methods. In contrast, other authors claim that hardly any progress is to be expected because of the inherently normative character of the literature. A final view is that progress in the literature on the social responsibilities of business is obscured or even hampered by the continuing introduction of newconstructs. This article explores which of these three views better describes the evolution of the literature during a period of 30 years and suggests implications for further research.


The present study was carried out at Abess, Alexandria, Egypt, during the two seasons of 2018/2019 and 2019/2020 to study the effect of water stress and foilar application of salicylic rates on yield and quality of wheat. This experiment was laid out in a split plot system with three replications in both seasons. The main plots were water stress treatments (normal irrigation, skipping the first irrigation at the age of 50 days, skipping the second irrigation at the age of 70 days, and skipping the third irrigation at the age of 90 days from sowing), while salicylic acid (SA) concentration (water = control, 1 mM;  2 mM and 3 mM) distributed in a sub plot in both seasons. The obtained results showed that sowing wheat cultivar namely Shandaweel- 1 with foliar application of salicylic acid (SA) twice at 50 and 70 days after sowing (DAS) at the rate of 2 mM/l under normal irrigation or skipping one irrigation at the first or the second irrigation achieved the highest mean value of yield, yield components and protein (%) in grain under study conditions at Abess, Alexandria Governorate, Egypt.


strength: raising prices, export taxes, insistence upon provision of raw materials, and above all, sabotage, absenteeism, and joining the Maquis. The author notes the three main stages of policy: the first until the check on the Eastern front, without very heavy pressure, followed by the Sauckel policy of draining workers to Germany, followed by the Speer policy of building the New European order in which France produces finished consumer goods in France and leaves armament production and components mainly to Germany. The chronological narrative is supplemented by case studies in coal, iron ore, bauxite, and aluminum, wolfram, and agriculture. Milward's conclusion that conquest pays in the short run, but not in the long, seems to require more exploration of the links between the imposing of heavy burdens of


A simple model of earthquake triggering and rupture propagation, based on concepts of earthquake mechanism commonly accepted, suggests that earthquake prediction (especially prediction of magnitude) might be very difficult, depending on the values of certain stress parameters. The concepts in the model suggest lines of research which may help to judge how successful the earthquake prediction effort might eventually be.


In view of the premature convergence problem of particle swarm optimization(PSO),a hybrid quantum-behaved particle swarm optimization algorithm(HQPSO)is presented by introducing the breeding strategy into QPSO in this paper.A method of 3-D route planning for unmanned air vehicle(UAV)is set up on the basis of the proposed HQPSO algorithm.The performance of HQPSO is compared with the QPSO and PSO with inertial weighting coefficients by using a statistical method.Simulation results demonstrate that HQPSO not only has stronger global searching ability,but also achieves a faster convergence speed compared with QPSO and PSO.


This report describes the development and application of techniques for the spectroscopic study of hazardous fuel compounds in soils. The objective is to obtain improved models of bulk pollutant transport through soils. Two approaches have been used for this study: one consists of in-situ measurements of electronic and vibrational interactions via ultraviolet-visible spectroscopy and infrared spectroscopy, respectively; the other incorporates analytical separation techniques to extract contaminants from soils and identify individual reaction products. Initially, montmorillonite clay has been chosen as a prototype soil sample because the structure of this clay is well characterized and spectroscopic results can be readily interpreted. Further simplification has been obtained by exposing the clay samples to individual fuel components rather than mixtures. An interpretation of one clay/fuel system has been accomplished. The plan is to gradually increase the complexity of the samples until typical field conditions can be modeled.


ABSTRACT A petrographic study was made on thin sections prepared from three well cores of the Duperow Formation of late Devonian age in western North Dakota. Except for argillaceous and carbonaceous zones, the following major rock types were recognized: Fine-grained limestone Calcarenitic limestone Calcarenite Biolithite Anhydrite and associated fine-grained rock Crystalline dolomite and strongly dolomitized limestone Recrystallization and dolomitization in micrites and calcarenitic rocks and merging of pellets have been common in the Duperow and have acted to subdue or obliterate original textures. Anhydrite is present in nearly all of the carbonate beds in one or more of the following forms; void-fillings, replacement of matrix and allochems, "nodules," "chicken-wire," and "layers." To what degree anhydrite represents replaced gypsum was not established. The biolithites consist primarily of stromatoporoids and associated corals and algae.

Means for depressing resonance discharge are discussed. (tr-auth)


Stanene, a graphene like two dimensional honeycomb structure of tin has attractive features in electronics application. In this study, we performed molecular dynamics simulations using modified embedded atom method potential to investigate mechanical properties of stanene. We studied the effect of temperature and strain rate on mechanical properties of α-stanene for both uniaxial and biaxial loading conditions. Our study suggests that with the increasing temperature, both the fracture strength and strain of the stanene decrease. Uniaxial loading in zigzag direction shows higher fracture strength and strain compared to the armchair direction, while no noticeable variation in the mechanical properties is observed for biaxial loading. We also found at a higher loading rate, material exhibits higher fracture strength and strain. These results will aid further investigation of stanene as a potential nano-electronics substitute.


Practical risk management for present and future spacecraft, including space stations, involves the optimization of residual risks balanced by the spacecraft operational, technological, and economic limitations. Spacecraft fire safety is approached through three strategies, in order of risk: (1) control of fire-causing elements, through exclusion of flammable materials for example; (2) response to incipient fires through detection and alarm; and (3) recovery of normal conditions through extinguishment and cleanup. Present understanding of combustion in low gravity is that, compared to normal gravity behavior, fire hazards may be reduced by the absence of buoyant gas flows yet at the same time increased by ventilation flows and hot particle expulsion. This paper discusses the application of low-gravity combustion knowledge and appropriate aircraft analogies to fire detection, fire fighting, and fire-safety decisions for eventual fire-risk management and optimization in spacecraft.


An article is an attempt to study the main processes of the interaction between German cities and universities in the late Middle Ages. The author also researched the main aspects of the foundation of universities in Germany and the role of German cities during the 14th and 15th centuries in their formation, financing and material endowment. It was carried out the classification of the sources of financial income to universities, including participation in this process by city councils, which exercised certain rights and responsibilities towards universities, and formed separate bodies of city government for the care of educational institutions, including so-called «provisors» or «deputies», paid scholarships and annual grants to the university's general expenses, granted salaries for teachers. Main attention is given to the cultural and scientific role of the higher education institutions, which they played for the German cities in during the late Middle Ages, namely the provision of educated professionals, that contributed to the economic and political development of these territories. It is also analyzed the social composition of students and university teachers, the proportion of burghers in this environment, their role in shaping the teaching staff of higher education institutions. It is carried out the conflicts between urban representatives, in particular artisans, and high school students. It is also researched the confrontations between municipal administration and the representatives of universities and the role of city council or princes in the settlement of such clashes. Particular attention is paid to conflicts between city councils and universities regarding the appointment of teachers, the procedure of rent payment for the use of city buildings, committing offenses in the city by students.


The overall acceleration constant or OAC of various comonomer systems was related to the chemical structure of crosslinking agents in an effort to establish workable relationships between expected curing properties and chemical composition of specific monomer mixtures. The overall curing rate (OCR) was found to be proportional to the volume concentration of several divinyl monomers (DVM) studied. The overall acceleration constant (K) was found to be inversely related to DVM connection number (CN/sub DVM/) according to: 1/K = 5.2 x CN/sub DVM/ - 10.55. The relative accelerating ability of DVM increased with the molecular bridge length the order being: ethylene glycol dimethacrylate : diethylene glycol dimethacrylate : triethylene glycol dimethacrylate : tetraethylene glycol dimethyacrylate = 1.00 : 1.36 : 1.64 : 2.18. The empirical equation for calculating the overall acceleration constant and prediction of curing times was derived and applied to four systems in this study. Extension of this prediction equation to published results on acceleration, observed in heat-catalyst systems, was found to be fully applicable. Agreement between predicted and published results was within + 5% error for all copolymer systems observed. 3 figures, 3 tables.


This paper considers the evaluation of the so-called Co-centered Orthogonal Loop and Dipole Uniform and Linear Array (COLD-ULA) performance by mean of the Statistical Resolution Limit (SRL). The SRL adressed herein is based on the estimation accuracy. Toward this end, nonmatrix closed form expressions of the Cramer-Rao Bound (CRB) are derived and thus, the SRL is deduced by an adequat change of variable formula. Finally, concluding remarks and a comparaison between the SRL of the COLD-ULA and the ULA are given. In particular, we show that, in the case where the sources are orthogonal, the SRL for the COLD-ULA is equal to the SRL for the ULA, meaning that it is not a function of polarisation parameters. Furthermore, thanks to the derived SRL, we show that generally the performance of the COLD-ULA is better than the performance of the ULA.


ABSTRACT: The aim of this study was to evaluate and to compare the possible inflammatory changes by screening acute phase proteins concentrations in healthy bitches subjected to ovariohysterectomy. Minimally invasive and conventional (laparotomy) ovariohysterectomies were performed in 17 client-owned adult female mixed breed dogs. Nine animals were subjected to minimally invasive and eight animals to conventional ovariohysterectomy. Blood samples were taken before surgery, 24, 48 hours, and seven days postoperatively. Serum C-reactive concentration was determined by a commercial ELISA kit and serum haptoglobin concentration was measured via hemoglobin binding assay, both previously validated for use in dogs. As the data did not meet the normal distribution criteria, the nonparametric Kruskall-Wallis was performed to compare quantitative variables between groups. One-way ANOVA and the Friedman test were used for multiple comparisons between time points, with a P<0.05 considered significant. C-reactive protein concentration was significantly different (P<0.0001) at 24 hours postoperatively between groups. There was no significant difference in haptoglobin concentration between groups. C-reactive protein and haptoglobin concentrations were significantly different at 24 and 48 hours postoperatively for minimally invasive and conventional ovariohisterectomies. These findings provided an overview of the short-term inflammatory effects produced by minimally invasive and conventional ovariohysterectomies.


At the end of the twentieth and beginning of the nineteenth centuries BCE, Assyrian merchants originating from Assur developed a long distance trade in Central Anatolia and settled there progressively in some forty towns. Their commercial activities prospered during slightly more than two centuries, a period traditionally called "Old Assyrian" or "kārum period." The center of their operations was located at Kanesh (modern Kultepe) where, according to written records dated to the first half of the nineteenth century BCE., several hundreds of them lived more or less temporarily.
Kultepe was divided into two major areas: the citadel with its palace, official buildings, and temples, and the lower city, often considered in the publications as the kārum Kanesh mentioned in the tablets. The site has produced up to now some 22,500 cuneiform texts: only forty tablets were found on the citadel, the remaining come from the private houses of the lower city (Michel 2003, 116-117; 2006; 2012). These archives, which belonged in the great majority to Assyrians, also provide data concerning the population of the lower city: natives, Assyrians, and other foreigners, though such divisions must be made, when filiation is unknown, by the language of personal names.
The status of the Assyrian settlement at Kanesh has been much debated. This chapter considers the recent and interesting suggestion of G. Stein to define the Assyrian kārums in Anatolia as "trade diasporas" (Stein 2008). A brief summary of the various translations proposed for the word kārum will be followed by an analysis of the Kultepe lower city population and its geographic distribution. The study of material culture affords a provisional understanding of the dynamic relations between Assyrians and the native inhabitants of the city over the two centuries covering the Old Assyrian period.


Government regulations soon will require many businesses to increase their reliance on alternative fuels. Here's how natural gas, ethanol, propane, and electricity fit into our not-so-distant future.


Electric vehicle (EV) fleets can provide ancillary services, such as frequency regulation, to the utility grid, if their charging/discharging schedules are coordinated appropriately. In this paper, a multi-level architecture for bidirectional vehicle-to-grid regulation service is proposed. In this architecture, aggregators coordinate the charging/discharging schedules of EVs in order to meet their shares of regulation demand requested by the grid operator. Based on this architecture, the scheduling problem of V2G regulation is then formulated as a convex optimization problem, which in turn degenerates to an online scheduling problem for charging/discharging of EVs. It requires only the current and past regulation profiles, and does not depend on the accurate forecast of regulation demand. A decentralized algorithm, which enables every EV to solve its local optimization problem and obtain its own schedule, is applied to solve the online scheduling problem. Based on the household driving pattern and regulation signal data from the PJM market, a simulation study of 1,000 EVs has been performed. The simulation results show that the proposed online scheduling algorithm is able to smooth out the power fluctuations of the grid by coordinating the EV schedules, demonstrating the potential of V2G in providing regulation service to the grid.


This report is a compendium of the available information on several topics of importance in defining the geologic setting of crystalline rocks in Maine, New Hampshire, Vermont, northeastern New York (the Adirondack Mountains), Massachusetts, Rhode Island, Connecticut, southeastern New York, northern New Jersey, and southeastern Pennsylvania. Crystalline rocks are defined herein as bodies of medium- to coarse-grained igneous and high-grade metamorphic rocks. The study was undertaken to provide background information to assist in evaluating the geologic suitability of such rocks for isolating high-level radioactive waste. Part 2 contains a series of maps showing the distribution of described crystalline rock bodies of the northeastern United States.


The dissertation investigates the design of a Youth Enterprise Hub on the east periphery of Mamelodi, east of the Pretoria's Central Business district. It aims to explore the potential for the restoration of social inequality within an emerging township economy in a context that has been historically deprived of any economic infrastructure. It suggests the integration of a train station, an informal community as well landfill through the proposal of an urban vision which investigates the possibility for the bridging of socio-economic exclusion through a new industrial ethos of innovation, information access, collaboration and skills development.


Recently indication for a possible variation of the proton-to-electron mass ratio μ=mp/me was found from a comparison between laboratory H2 spectroscopic data and the same lines in quasar spectra. This result will be put in perspective of other spectroscopic activities aiming at detection of variation of fundamental constants, on a cosmological as well as on a laboratory time scale. Furthermore the opportunities for obtaining improved laboratory wavelength positions of the relevant H2 absorption lines, as well as the prospects for obtaining a larger data set of H2 absorptions at high redshift will be presented. Also an experiment to detect Δμ on a laboratory time scale will be discussed.

Isolated periodic dystonia in the arms and legs was the first manifestation in three siblings with Leigh's syndrome. The symptomatology is identical and progressive in both brothers, whereas the progressive, dystonic movements of the 14-year old sister have disappeared completely for the last three years. CSF lactate was increased in both brothers. All siblings showed MRI abnormalities of the globus pallidus with different pronounciation. Since the therapeutic use of alpha-liponic-acid the recurrent encephalopathic episodes disappeared in both boys without affecting the dystonic movements. The girl is asymptomatic without any therapy. Leigh's syndrome is a differential diagnosis in children with a first manifestation of periodic dystonic movements.
