The utility model discloses a circular arc tooth 2K-V planetary speed reducer. A transmission mechanism in which a circular arc tooth planetary gear is used for a 2K-V type wheel system is provided. The circular arc tooth 2K-V planetary speed reducer is composed of a center gear shaft, an output disk, needle gears, a planetary rack, and a crank shaft. An involute planetary gear which forms an outer engaging pair with the center gear shaft, and a circular arc tooth planetary gear which forms an inner engaging pair with the needle gears which are sheathed on the planetary rack and the outer circumference of the output disk by main bearings are respectively arranged on the crank shaft. The tooth profile of the circular arc tooth planetary gear is a full circular arc tooth profile. The circular arc tooth 2K-V planetary speed reducer has the advantages of stable transmission and good carrying capacity. A circular arc tooth and a needle tooth are internally engaged, the contact intensity of tooth surfaces is high, and the relative slide between wheel teeth is small. The integral structure more commonly has poor teeth transmission and smaller volume, and a transmitting ratio can achieve i=6-300. Due to the fact that the circular arc profile is easy to manufacture, transmission precision is easy to control, and high positioning precision and transmission precision can be realized.


Consumers are increasingly buying Internet-connected appliances, referred to as the Internet of Things (IoT), for their homes. These IoT devices can collect a lot of data and enable users to manage their smart home environment. However, it can also pose huge risks to consumers privacy and security. A remote intruder who may illegitimately access these devices can obtain information for his gain or harm other entities. This paper aims to experimentally evaluate vulnerabilities of consumer IoT devices against cyber-attacks. We first develop a number of test suites to conduct our evaluation in four categories: confidentiality of data exchanged by IoT devices, integrity and authentication of their communication, their access control and availability, and their capability to reflect DDoS attacks. We then give each IoT device an overall rating (good, average, poor) based on threats we identified in each category. Lastly, we apply our evaluation to four representative households namely home security, health monitoring, energy management, and entertainment which collectively include 17 consumer IoT devices that are available on the market, and illustrate what threats may emerge for each household if IoT devices are compromised.


Florida is the second largest producer of orange juice in the world today, second only to Brazil. However, the production costs in Florida are nearly three times the production costs in Brazil. Reducing production costs is vital to price U.S. citrus products competitively and remain profitable in the global market. Harvesting accounts for about half of the production costs in U.S. citrus production, so mechanical harvesting could reduce costs by increasing the rate of harvest, and thereby increase profits for Florida growers. Mechanical harvesting research for citrus began in the 1950s to address the inadequate availability of labor. This research has been led by the Florida Department of Citrus, the USDA, and the University of Florida.


As we near the end of the calendar year, undergraduate and graduate medical education programmes set out on another round of highstakes decisions about which trainees will make up their cohorts. They do so in a time of flux, amidst a period of renewed focus on diversity and equity and on the heels of an admissions season whose format was subjected to considerable experimentation in response to the COVID-19 pandemic. Given this context, the effort by Lievens et al. to provide programmes a straightforward means to help ensure their cohorts are diverse and positioned for success is timely. Using Pareto optimization, a mathematical modelling approach developed initially in economics, the authors propose a tool for weighing the attributes of medical school and residency applicants to achieve an optimal balance of diversity and 'predictiveness' in selection.


By adding an ancilla photon in the fixed polarization state and making good use of quantum parity check, the polarization state of a photonic qubit, which may or may not be entangled to other systems, are successfully protected against collective decoherence.


The problem of output feedback variable control of discrete-time linear systems with unmatched uncertainties is studied in this paper. The output feedback control doesnpsilat need state available and estimated state. First, the sliding surface is designed by using linear matrix inequality (LMI) technique when there exists the unmatched uncertainties. The sufficient condition for the existence of stable sliding surface is derived in terms of LMIS. Then the design of sliding mode control is presented according to the reachability condition. Finally, an illustrative example is presented to show the feasibility and effectiveness of the proposed method.


The traffic authority of New South Wales has been engaged in a project assisted by the Australian government under the Transport (Planning and Research) Act, 1974, to investigate the feasibility of implementing bus priority techniques at traffic signal locations. The broad objectives of the project were to determine appropriate strategies to be used at signalized intersections for giving priority to buses in order to reduce the delays experienced by these vehicles. The effect of these strategies on other road users was also investigated. The approach adopted was to develop control systems and test these with carefully designed field experiments. This report describes the strategies developed and the experiments carried out to test them. Also described in this report is a computer program developed to simulate bus priority strategies.

We studied increase in cancer incidence in the population and the dynamics of the carcinogenic benzo(a)pyrene content in the atmospheric air of cities in the Irkutsk Region. Sources of air pollution boilers and household furnaces, aluminum production, motor vehicles, forest fires were considered. Individual and population carcinogenic risks of benzo(a)pyrene for the health of the population in industrial, agricultural and South Baikal cities were assessed. We also could establish the tendency of increasing risks and the dependence of the incidence of malignant neoplasms in the population on the content of benzo(a)pyrene in the atmosphere. The conclusion was made about the need to assess pollution sources, about the development of a monitoring system for benzo(a)pyrene and its analogs - polycyclic aromatic hydrocarbons - in the environment.


Despite conceptual benefits expressed for comparative advertising, most studies have found it relatively ineffective and lacking credibility. By means of a field experiment, the author explores the impact of the attribution theory tool of two-sided claims on the credibility and effectiveness of comparative advertising. Results suggest that the effectiveness of comparative advertising might be significantly increased with such tactics.


Diabetes is a chronicle disease where the body of a human is irregular to dissolve the blood glucose properly. The diabetes is due to lack of insulin in human body. The continuous monitoring of blood glucose is main important aspect for health care. Most of the successful glucose monitoring devices is based on methodology of pricking of blood from ear lobe or finger. There is requirement to develop the Internet-Medical-Things (IoMT) integrated Healthcare Cyber-Physical System (H-CPS) based Smart Healthcare framework for glucose measurement with purpose of continuous health monitoring. To fulfill the imperatives for non-invasive blood glucose monitoring system, there is a need to configure an accurate measurement device. Noninvasive glucose-level monitoring device for clinical test overcomes the problem of frequent pricking for blood samples.


Twelve cucurbits namely cucumber, muskmelon, watermelon, round gourd, bottle gourd, smooth gourd, ridge gourd, bitter gourd, pumpkin, longmelon, ash gourd, snake gourd and pointed gourd were tested for the relative population and host preference of fruit fly. The maximum emergence of fruit flies were found in musk melon and bottle gourd, minimum in round gourd. The longmelon was recorded as most preferred host, bitter gourd as preferred host, muskmelon and round gourd were categorized as moderately preferred host while cucumber, bottle gourd and snake gourd recorded as least preferred hosts.


This report constitutes a major output of the project Designing Mental Health Law in Developing Countries: A Case Study of Lesotho which was directed by Professor Peter Bartlett, Nottinghamshire Healthcare NHS Trust Professor of Mental Health. The report provides examples of best practice, suggestions for future legislative reform initiatives and the direction of legislation and policy regarding service provision for people with mental disabilities.


For those producers considering a full-scale marketing program for their natural gas, the availability of supply should not lead one to believe that the sales of those supplies can be accomplished by a simple phone call to several potential purchasers. This paper traces the history of natural gas marketing since the passage of the Natural Gas Policy Act through the implementation of the Federal Energy Regulatory Commission's Order 500.


ABSTRACT This empirical study seeks to identify effective methods for infusing community material into a clinical social work program. It draws from Diffusion of Innovation Theory (Rogers, 1995b) and the Transtheoretical Model (Prochaska, DiClemente, &Norcross, 1992) to guide implementation. Based on qualitative and quantitative data from a variety of sources, the results identify variables critical in the change process and some preliminary outcomes of that change. Findings suggest that teaching community content can be enhanced through developing a pool of outside community guest speakers and field trips, addressing the varying faculty development needs of professors teaching macro and micro social work courses, and defining and redefining the concept of community during implementation and change processes.


The Classical Review vol. 62 no. 2 © The Classical Association 2012; all rights reserved time. Of course, it strikes us as implausible. That is not surprising as we are the heirs of a well-developed and complex fi eld of psychological study. But at a time when no one had put forward a theory of a partitioned soul, a view that cognised the emotions was not at all implausible. The second response takes quite a different approach and concedes that the view was implausible, but does not fi nd a reason for doubting that Socrates held it. The theory of forms strikes most contemporary philosophers as quite implausible, but that is no reason to doubt that Plato sincerely put forward such a theory. To the charge that the phenomenology of fear is left unexplained, one must note that phenomenology in general is still left unexplained. It is hard to see how a problem for everyone is a problem for Socrates. Finally, B. and S. object that Socrates' resistance to fear is incomprehensible. But they are mistaken in thinking Socrates is resistant to fear. Socrates is resistant to the fear of death because he does not believe death is a bad thing. He is not resistant to the fear of injustice, because he believes that it is harmful to him to become unjust. He is resistant to the fear of death because that fear is the belief that death is harmful, and Socrates lacks that belief. But he believes injustice is harmful and consequently fears being unjust. My discussion of the passages from the Apology does not properly develop a view of Socrates' moral psychology or vindicate the traditional view. However, it shows that B. and S. have ignored relevant textual support for the traditional view. In this way, they fail adequately to motivate the attribution of a more robust moral psychology to the Socrates of Plato's early dialogues.


In the past, computers had a simpler life, few applications had network capabilities and users only wanted to connect to Internet in few specific situations as to check emails, view some mostly plain-text webpage or to play few games with their friends using a "not very wide" bandwidth. But several aspects have changed nowadays, we have better connections, more content available on Internet (the biggest computer network ever known), there are new devices able to connect allowing the presence of more network elements than before and, in addition, the rapid advances in real-time supported applications that are expected, make it difficult to manage them as has been done. Today's network applications require extensive human involvement in management but we need a more independent (smart) network so research community has been developing lot of work in the last few years trying to ease this issue and to introduce autonomic behaviour in computer and telecommunication networks1. Manage a network is a complex task where the purpose is to control the behaviour of their elements in order to fulfil some high level goals. The automation of networks and systems thus far has been applied to simplified problems. Typically, we can find some works about improving routing2; configuring a network element to better support some application; or controlling the compliance of contracts between peers. Among the different enabling technologies for automate network communications the policy based management is one of the most representatives. This paradigm allows segregating the rules that govern the behaviour of the managed system from the functionality provided by the system itself (Boutaba & Xiao 2002). This is particularly useful in environments where it is necessary to dynamically change goals and add new services or resources. The most well developed implementations of this paradigm rely on pre-programmed rules based on logic. Nevertheless, to be called autonomic, a system must show a degree of flexibility to self adapts to changes and this is hardly achievable by means of static policies. Then, it emerges the need of learning and to figure out the mechanism that will lead to new policies. Another important aspect of a network is that it has high and low level goals so it would be important to understand the whole vertical structure from sending/receiving bits till more complex application tasks in order to combine and enforce the best action choice.

O N MAY 25, 2010, the Bureau of Economic Analy sis (BEA) will release the initial results of its com prehensive revision of the annual industry accounts. These widely used accounts provide statistics on in dustries—their interactions with each other and the roles they play in the economy. More specifically, the annual industry accounts provide statistics on 65 in dustries and commodities, detailing the goods and ser vices produced and purchased as part of production processes and the incomes earned from production. The value of the accounts is symbolized by the "use" table (chart 1), which shows the interdependencies among industries, the contribution of each industry to gross domestic product (GDP), and expenditure-based categories of GDP (consumer spending, exports, in vestment, government spending). The annual industry accounts—which include the annual GDP by industry accounts and the annual in put-output (I-O) accounts—are typically updated once a year in annual revisions. Comprehensive revi sions, which occur every 5 years, typically go beyond annual revisions by incorporating more detailed meth odological and other changes. Traditionally, compre hensive revisions adopt two major types of improvements: (1) changes in definitions and classifi cations that update the accounts to more accurately portray the evolving U.S. economy and (2) statistical changes that update the accounts to reflect the intro duction of new and improved methodologies and the incorporation of newly available and revised source data. While this comprehensive revision of the annual in dustry accounts is in keeping with traditional compre hensive revisions, BEA will soon move toward "flexible annual revisions," which will allow for annual im provements that traditionally were reserved for com prehensive revisions (see the box "Flexible Annual Revisions"). This article presents the major changes that will be introduced in the 2010 comprehensive revision of the annual industry accounts (chart 2, page 23). This com prehensive revision incorporates the results from the 2002 benchmark I-O accounts and the 2009 national income and product accounts (NIPAs) comprehensive revision as well as a range of other changes that, taken together, provide more accurate industry statistics.1 It also incorporates an improved methodology to pre pare an integrated time series of annual industry ac counts for 1998–2008.


The method for preparing personalized printed matter comprising at least first and second sides involves making contact with a computer via a network, the input of data to the computer of data relating to the printed matter, the selection of one or more motifs or patterns for at least a first side of the printed matter, the choice or creation of one or more patterns (105) for at least a second side of the printed matter. The insertion of personal details (106) in conformity with the pattern is made on the second side. One or more codes are generated for addition to the personnel data. At least one of the codes is fed to the personal details for the second side.


This study aims to investigate how far the readiness of Madrasahs in providing disability-friendly services, what are the obstacles, and how is the government's disabled-friendly services in madrasahs. This is qualitative research with the case study of 4 madrasahs in Central Java and DI Yogyakarta. Data were collected through observation and in-depth interviews and analyzed using a thematic analysis technique. This research finds several important findings. Firstly, the commitment to disabled-friendly services is already there, however, the quality needs serious improvements such as the lack of standard and user-testing of the facilities so that it can provide appropriate services as intended. Secondly, the biggest obstacle to providing disabled-friendly services is the mindset of institutions. Therefore, a change in the mindset of the institution is needed to provide disable-friendly services aimed at improving long-term and fair services.


A novel design of a probe-fed stacked microstrip antenna for obtaining dual-band circular polarization (CP) radiation is presented. By properly selecting two elliptic patches of different axial ratios in the proposed design, and introducing a small air-gap layer between the two patches, dual-band CP radiation can be obtained by exciting the top elliptic patch using a single probe feed. Details of the proposed antenna design and experimental results for the obtained dual-band CP performances are presented and discussed. ©2000 John Wiley & Sons, Inc.

The recent emergence of commercial, high repetition rate, intense lasers opens up new prospects for applications. Of particular interest is the production of energetic proton beams through the interaction of an intense laser with a hydrogen target: this beam can then be used e.g. for proton therapy (cancer treatment), or for neutron production through interaction of the proton or deuteron beam with a secondary target. If physical processes involved in the production of protons have started to receive satisfactory explanations, the reliable production of protons at high repetition rate without any debris is still an issue. In this context, SBT has developed different cryostats to generate thin ribbons of hydrogen through extrusion of solid hydrogen, and optimize and predict the conditions for extrusion. In this article, we show, how thin hydrogen ribbons are produced, and high energy proton beams are generated. A few results are given, and future plans are discussed


- Security is also desired to be proper in order to data to be shared securely so we have reviewed some cryptographic concept which will be used in our paper to implement the proposed work. Here we have explored the concept of cryptography, Diffie-Hellman, Hash Functions.


This article empirically examines the external effect of family literacy on the earnings of illiterate workers. Considering recent findings that rural nonfarm sectors in developing countries are becoming more important in determining the welfare of households, this article tests two hypotheses: (1) an illiterate person living with literate members (i.e. a proximate illiterate person) is more likely to find a job in the nonfarm sector than is an illiterate person living with no literate person (i.e. an isolated illiterate person) and (2) wage income of a proximate illiterate worker is higher than that of an isolated illiterate worker. The empirical results suggest that proximate illiterate persons earn higher wages than isolated illiterate persons because they are more likely to be employed in the nonfarm sector.


Due to its well-performed capabilities of anti-electromagnetic interference, low-cost and high-sensitivity, interferometric optical fibre sensor has been widely used in the security systems of oil and gas transportation these years. The main part among those systems is the classification of intrusion signals, obtained from optic fibre Sagnac interferometers. Based on sparse representation, we analyse the characteristics of the intrusion signals and argue that it offers the key to addressing this kind of classification problem. The most critical thing, however, is that whether we can acquire sufficient number of features and the right sparse representation. Combined with support vector machine(SVM), a new method is proposed for intrusion detection by casting the classification problem as finding sparse representation of testing samples with respect to training samples. To evaluate its performance, the proposed method is applied to lots of datasets and compared with several other machine learning methods.


This experiment, designed for the first time in the Middle East region to sustain Coregonus lavaretus production, examined the efficacy of a live organism (Brachionus plicatilis), an artificial diet (48% crude protein) and a mixed feed for the first 3 month of rearing fry. Nine rearing cages were floated on the surface of a natural pond supplied with hyporheic-zone river water, each containing 150 numbers of white fish fry, where they were treated with each of the three diets in triplicates. The fry were fed eight times daily starting at the onset of exogenous feeding. Results showed that fry utilized live organisms more efficiently than the artificial and mixed diets. Rotifer-fed group consistently showed higher growth rate during the entire experiment. Length increment (29.6 mm), weight gain (572.3 mg) after 12 weeks of feeding were higher (P < 0.05) in this group. Also, their mean weekly specific growth rate (4.97% day−1) was the highest and feed conversion rate (2.97) was the lowest among all treatments. Survival rates of the fry declined from 75% to 61.4%, from 74.3 to 45.8% and from 72.7 to 54.5% for live feed, mixed diet and artificial diet, respectively.


A review article on the International encyclopedia of social sciene. Within the context of student unrest & the denunciation of established soc sci, this work is applauded as a monument for tolerance. Criticism is developed along 3 lines of relevance: interdisciplinary connectedness, societal engagement, & the acquisition of a global perspective. The 17 Vol's are as yet too much a product of Western soc thought. They are at the same time a valuable survey of the state of the soc sci's in the 1960's. AA.


The writer of tlus review once had the pleasure of meeting Dr. Milton J. Rosenau, then Professor of Preventive Medicine and Hygiene in the Harvard Medical School, at the house of Sir Arthur Newsholmc. Discussing lus textbook, Dr. Rosenau was pleased to know the value set upon it by British students of public health. Indeed, one or two of the questions set at the higher examinations in that subject could not be answered adequately except by a reader of that work. The book stands also on the shelves of every enlightened medical officer of health, sanitary engineer or sanitary inspector, for, in Dr. Rosenau's

This paper reviews the actualization of the Kantian conception of a fair and peaceful international order, which Rawls and Habermas have tried to accomplish on some of their recent writings. On his last book, Rawls argues that the democratic structure of the state's institutions is a necessary condition for international peace, even more important than the creation of international institutions. This thesis can be completed with some of Habermas's considerations about the relations between state and nation: if the states (even the democratic ones) have to be peaceful, it is necessary that societies are integrated by postnational forms of collective identity.


From 1 October 2006 to 31 January 2007, 213 confirmed cases of measles occurred in the Barcelona Region, resulting from the importation of one case.


Detailed results are given of the steady-state characteristics, over the current range 4-40 A, for d.c. arcs in air burning through a 5 mm bore in a stack of water-cooled disks. The corresponding decay of the conductance has been determined over a period of 300 μs following rapid interruption (similar 1 μs). These measurements have also been obtained under externally imposed gas-flow conditions (0-2·5 1. min−1). It has been found that both the steady state and recovery are dependent upon humidity and, furthermore, that the recovery is sensitive to the radial gas flow which is generated after interruption.


In the Kyrgyz Republic, 52% of all deaths are due to cardiovascular diseases, of which 2/3 is coronary artery disease (CAD) (1). The implementation of the ACC/AHA/SCAI Guideline for Coronary Artery Revascularization 2022 (2) is a necessary objective. This Guideline is the result of joint work of the American Heart Association, the American College of Cardiology and Society for Cardiovascular Angiography and Interventions (2). These recommendations are based on recent randomized clinical trials with a high-degree of evidence. However, their full implementation is hampered by local problems in equipment and skills. Unfortunately, the government does not provide the patients with consumables for coronary angiography, balloon angioplasty and stenting. Everything is purchased at their own expense. Therefore, primary percutaneous coronary interventions (PCI) is not performed in all the regions of the Kyrgyz Republic. The next reason for the difficulty in introducing primary PCI is the availability of a catheter laboratory in only three cities of the country. In four out of seven regions, there is no angiographic facility at all. In this regard, the main approach for the treatment of acute myocardial infarction with ST-segment elevation (STEMI) is thrombolytic therapy. In a small proportion of patients in cities where there is a catheter laboratory, a pharmaco-invasive reperfusion method is used. The situation is especially bad with the treatment of STEMI in the presence of pulmonary edema, cardiogenic shock. In this category of patients, PCI is challenging due to the lack of experience, absence of intra-aortic balloon pump and other means of mechanical circulatory support. Another problem is that in stable patients with acute myocardial infarction, if PCI is performed, then coronary artery bypass grafting is not performed in all cases with indication. After reviewing the clinical guidelines, we would like to note the recommendations that can be put into practice right now. The implementation of Heart Team approach Recommendations: In patients for whom the optimal treatment strategy is unclear, a Heart Team approach that includes representatives from interventional cardiology, cardiac surgery, and clinical cardiology is recommended to improve patient outcomes (I, B-NR). -The implementation of SYNTAX, STS scores Recommendations: In patients with multivessel CAD, an assessment of CAD complexity, such as the SYNTAX score, may be useful to guide revascularization (2b, BNR). -The implementation of physiological methods of assessing lesion significance fractional flow reserve (FFR) or instantaneous wave-free ratio (iFR). Recommendations: In patients with angina or an anginal equivalent, undocumented ischemia, and angiographically intermediate stenoses, the use of FFR or iFR is recommended to guide the decision to proceed with PCI (1, A). In stable patients with angiographically intermediate stenoses and FFR >0.80 or iFR >0.89, PCI should not be performed (3, B-R).


In view of the problems existed currently in the management mode of liberal arts labs,five aspects in management are suggested,which is establishment of a consummate organization,construction of a new management system,establishment of an open mechanism,development of a high-effective information platform,and formulation of regulations.The five aspects were applied into the construction of National Liberal Arts Experimental Teaching Demonstration Center of Zhejiang Normal University,and achieved fruitful results.


We present a narrow-bandwidth (167 pm) few-nanosecond fiber laser based on tapered fiber amplification and phase modulation to mitigate stimulated Brillouin scattering (SBS). We compare the use of chirped diode seeding and standard sinusoidal phase modulation. Below SBS appearance threshold, output temporal profiles can be accurately tailored. Typical results for flat-top profiles include 170 kW peak-power (for 3 ns duration) and 1.25 mJ pulse energy (for 10 ns duration).


The Territory's attempts to sell the seas off our coast to countries like Japan as a reliable source of gas has been dealt a blow with the $6.6 billion Greater Sunrise gas project teetering, CLP Leader Terry Mills warned today. Mr Mills said he fears the worst after learning that an investor briefing has been told by Woodside's director of gas and commercial, David Maxwell that "the project is likely to stall." "This would be a serious setback for the Territory and send out the worst possible message to potential gas investors considering business in the seas off the Territory coast," Mr Mills said. "Investors in Japan are well aware of the gas potential of the Timor Sea but they view fiscal certainty as paramount, and if this can't be provided then they will quickly look elsewhere to other more reliable sources of supply." ``There is a very real risk that in a few weeks East Timor will not have a project and neither, sadly, will the Northern Territory." Mr Mills said the new demands by East Timor that the Australian Government pay more than $2.6 billion in compensation for oil produced from Timor Sea fields since 1999, had further complicated negotiations on a maritime boundary between the two countries. "As it is the project has been put in jeopardy by the demand that Sunrise partners Woodside and ConocoPhillips take the gas to East Timor rather than Darwin," Mr Mills said. "Now there is a demand for $2.6 billion to be paid by the Australian Government in compensation. East Timor also wants the companies that invested in developing the Laminaria, Corallina and Buffalo oil fields to pay at least $600 million in compensation for royalties.


The problem of automatically synthesizing programs from formal specifications can be stated as, "constructively prove that there exists a program P which transforms valid input into output satisfying the required output assertion." If Prequires a loop, the proof will contain an induction. This is beyond the ability of current theorem provers and synthesis systems. In this paper, the loop invariant is used to reduce the problem of synthesizing loops to that of synthesizing three loop free sections — initialization, assignment to loop control variables, and assignment to all other program variables. The three sections are then assembled into a standard loop form, namely "(initialization) WHILE B DO (loop body) OD". Second order theorem provers adequate for these subproblems have not yet been developed. Therefore, heuristics are presented for synthesizing the three sections. Several examples are presented.


Educating the adolescent.-One of the outstanding achievements of the last two decades of educational progress is a truer knowledge of the adolescent. Much has been done in research and scientific investigation with respect to adolescence since Hall's work appeared nearly a quarter of a century ago. Psychologist, teacher, and administrator have found the challenge of adolescence most engaging, and the results of their earnest and painstaking work find expression in fundamental changes in that field of education in which the adolescent is of chief concern, namely, the secondary school. The psychologist has explored adolescence to discover the interests and predispositions that give a uniqueness to the adolescent. The administrator has sought to make such modifications in organization and administration, such changes in curriculums and programs of study, and such introductions of extra-curriculum activities as will best meet the fundamental needs of the adolescent. The teacher has not been unmindful of his responsibility respecting the problem of instructing the adolescent.


Computer generated displays are a powerful and flexible tool for presenting data to the operators of nuclear power plants. Such displays are currently being developed in industry for use as safety parameter displays and for use in advanced control rooms. There exists a need for methods to objectively evaluate the effect of these displays, positive or negative, on the performance of control room personnel. Results of developing one such method, noninteractive simulation, and the two experiments that were performed to determine if it can be used as a method for evaluating computer displays are presented. This method is more objective and powerful than pencil and paper methods because it measures human performance rather than opinion or perference, has excellent control of the experimental variables, and has a higher fidelity to the control room environment. The results of these experiments indicates that the present methodology does not differentiate among the display types tested at a statistically significant level. In other words, all display types tested worked equally well in providing operators needed information.

The nano-composite of the phosphoric acid derivative of fullerene ([PO(OH)2]2CC60) with SiO2 was synthesized using the in-situ reaction from [PO(OH)2]2CC60 with tetraethoxysilane (TEOS). The nano-composite was characterized using FT-IR measurements, and its morphology was observed using SEM. The humidity dependence of their proton conductivity for both [PO(OH)2]2CC60 and its nano-composite was investigated. The proton conductivity of the nano-composite is increased more than one order of magnitude higher than that of [PO(OH)2]2CC60 under low relative humidity. This is probably because the more proton conductive sites are generated by SiO2. However its proton conductivity is lower in the humidity range above 60%, probably because the number of the highly dissociative protons from phosphoric acid is decreased after being combined with silica.

Shield comprising a window transparent to light, the light transparent window is disposed within the cavity adjacent to the shield. The optically transparent window allows the annealing energy through the optically transparent window and the substrate is irradiated. Shield further comprises one or more gas inlets and one or more gas outlets, the gas inlet and the gas outlet for introducing and removing purge gas from the purge gas cavity within the shield. The volatiles were removed using a purge gas during the heat treatment to a component or components of erosion, and purge gas is utilized to provide a predetermined composition of gases (such as oxygen-free) to the heat treatment zone.


Introduction: Radionuclide liver-spleen scintigraphy has been used to identify diffuse hepatic disease. Since the visual interpretation of planar images is prone to imprecision, quantitative parameters using SPECT are more objective and accurate. Methods: We proposed a method for the estimation of whole body phytate uptake ratios of the liver and spleen using whole body liver-spleen scan and regional SPECT. Thirteen patients were assessed with our method and Hoefs' semiquantitative parameters. Results: In these thirteen patients, the phytate uptake ratio of the liver ranged from 26.4% to 76.9%,and that of the spleen ranged from 3.2% to 43.0%.The phytate uptake ratio of the liver correlated very well with the Hoefs' parameters that had been studied extensively to represent hepatic functional reserve. Conclusion: Whole body phytate uptake ratio of the liver which is calculated by our method correlates very well with Hoefs' parameters and should be closely correlated with the severity of diffuse liver disease.


Simple Summary Plumage color is one of the economic characteristics of poultry. The most common plumage colors in adult geese are white and grey, so research on goose plumage color is relatively scarce compared with the molecular basis of research on chicken plumage color inheritance. Nevertheless, whether the formation of a black phenotype on the Holdobaggy geese newborn dorsal plumage color is associated with gender needs further profound study. Our study researched the gender identification of the newborn Holdobaggy geese based on plumage color and the expression levels of relative genes for melanin, which offers a theoretical basis for gender identification. Abstract In production practice, we have found that the gray and black down on the backs of the Holdobaggy goslings is usually darker in females than in males. Melanin is the key pigment affecting the color of poultry plumage. Therefore, to determine whether the darkness of the dorsal plumage of the Holdobaggy goslings is related to sex, we study the melanin in the feather follicles of the dorsal skin during the embryonic period. The feather follicle structure and melanin distribution on the dorsal surface of the goose embryo is observed by HE staining and melanin-specific staining. The melanin content in the feather follicles of the dorsal skin of goslings is determined by ELISA. The results showed that the melanin content is higher in female geese than in males (p < 0.05). In addition, we also analyze the mRNA and protein expression levels of melanin-related genes (TYRP1 and ASIP) by quantitative real-time PCR and Western blotting analysis. The results show that the mRNA expression level of TYRP1 is significantly higher in the females' dorsal skin feather follicles (p < 0.05), while the mRNA expression level of ASIP is significantly higher in the dorsal skin feather follicles of male geese (p < 0.05). In conclusion, the difference between males and females in the color of the black feathers on the dorsal track of the Holdobaggy goslings is verified, and it is feasible to identify the sex by the initial plumage color.

The agronomic effectiveness of phosphate fertilizers is strongly affected by reactions of P with soil constituents. The transformation of P added to soil and the effect of soil properties on these transformations was investigated for 14 alkaline and calcareous soils from southern Western Australia. The decline of NaHCO 3 -extractable P (Olsen-P) with time followed a second order kinetic equation. The kinetic rate constant (k) increased with increasing oxalate-extractable Fe (Fe o ), citrate-dithionite-bicarbonate (CDB)-extractable Al and Fe (Al d and Fe d ), CaCO 3 -free clay content, cation-exchange capacity (CEC), and ratio of CDB-extractable Fe (Fe d ) to active CaCO 3 equivalent (ACCE), and k decreased with increasing ACCE. A combination of these soil properties described 93% of the variation in rate constant, of which 78% of the variation was predicted by the Fe d /ACCE ratio alone. A combination of clay related properties (Al d , clay, Fe o , and CEC) described 62% of the variation in Ca 2 -P determined by specific extraction. Carbonate-related properties (ACCE and CCE) together described 71% variation in Ca 8 -P. Clay-related and carbonate-related properties jointly described 97% and 81% of the variation in Fe-P and Olsen-P respectively. Surface area (SA) and Al d together accounted for 43% of the variation in Al-P. Scanning electron microscopy analyses showed that added P was uniformly distributed in the soil matrix to the limit of the spatial resolution of the technique ( 2. μm).


In the Longxi-Hongkou National Nature Reserve,seed plants are estimated at 140 families,790 genera,and 2 183 species,and their geographic distribution types belong to the temperate flora which is characterized by the domination of temperate flora components.The flora is of ancient origin,consisting of many primitive families and genera,and relic species.There are many monotypic and oligotypic genera,and relatively large families and genera with more than 10 species are also common.The distribution of families,as well as genera and species,exhibits evident temperate characteristics.


Techniques of exploratory data analysis are used in the construction of simple approximations for the percentage points of the chi-square distribution. The approximations are direct functions of the degrees of freedom and the tail probability. They are more accurate than Hoaglin's approximations.


Most high current proton synchrotrons, such as The Rapid Cycling Synchrotron (RCS) of The China Spallation Neutron Source (CSNS), are operated under the transition energy, and the natural chromaticity is small. These proton synchrotrons can work without chromatic correction. To reduce the tune spread produced by the chromaticity, chromatic correction is considered by using chromaticity sextupoles for this type of proton synchrotrons, such as J-PARC and SNS. An optimized chromatic correction scheme is proposed for CSNS/RCS. The effects of chromaticity sextupoles on the optical functions are examined. 3-D simulations with and without space charge effects are performed by using the code ORBIT. INTRODUCTION The China Spallation Neutron Source (CSNS) is an accelerator-based facility. It consists of a 1.6-GeV Rapid Cycling Synchrotron (RCS) and an 80-MeV linac. RCS accumulates 80 MeV injected beam, and accelerates the 1.56×10 particles to the design energy of 1.6 GeV, and extracts the high energy beam to the target. The lattice of the CSNS/RCS is triplet based four-fold structure. Table 1 shows the main parameters for the lattice [1] [2]. Table 1: Main Parameters of the CSNS/RCS Lattice Circumference (m) 227.92


Objective To develop behavior-psychological scale evaluation of fruit and vegetable intake in adolescent, and assess its validity and reliability. Methods A total of 3600 junior students were investigated by questionaire through multistage sampling method. The reliability was assessed using Cronbach ' s α and split-halves reliability test. Exploratory factor analysis and confirmatory factor analysis were used to test the structure validity. The content validity was tested by entire- dimensions correlation coefficient(IIC), correlation between the scores and dimension. Results The internal consistency reliability for total scale score(Cronbach ' s α = 0.917), and Cronbach ' s α of four dimensions were 0.917, 0.869, 0.679, 0.846 respectively; Four dimensions split-halves reliability ranged from 0.312 to 0.882. Exploratory factor analysis revealed that three dimensions were well incorporated, and the cumulative contribution rate was more than 50%. Confirmatory factor analysis showed that the absolute goodness of fit was satisfied(GFI=0.983, AGFI=0.971, RMSEA=0.030, 90% confidence interval=0.028-0.032), The results of IIC showed that Spearman correlation coefficient in four dimensions and their items were 0.508-0.778, 0.719-0.825, 0.561-0.790, 0.659-0.779, respectively. Each dimension had moderate relationship, and r ranged from 0.474 to 0.593. Conclusion The reliability and validity of the behavior- psychological scale developed was good, and can be applied in behavior-psychological measurement of adolescent fruit and vegetable intake.


Fast food and chain restaurants often give the menu items descriptive names related to the production processes (e.g., baked, fried, grilled, glazed). Do these descriptions in a food's name provide a useful indication of its calorie content?


Taking JZF-45400 damping spacer for an example,based on ANSYS finite element analysis software,finite element model of damping spacer is established.And then it calculates load values under the conditions of circuit normal operation,short circuit,unbalanced force,and analyzes static mechanical properties of damping spacer.The results show that the cable clamp of damping spacer is the weakest part of the force.Therefore,it suggests that the strength of cable clamp should be enhanced for making damping spacer design more reasonable.


Y-doped alumina was sintered under ultra-pure experimental conditions to full density without experiencing abnormal grain growth (AGG). Yttrium was fairly homogeneously distributed at the grain boundaries with the average value of =5.4±0.7 at./nm2. However, AGG was observed in Si-contaminated Y2O3-doped alumina samples. At the early stages of AGG exaggeratedly grown alumina grains had curved, "rough" grain boundaries. At later stages of AGG evolution, faceted grain boundaries with thick grain boundary films developed. Frequently observed Y-Al-O precipitates in clean Y2O3-doped alumina specimen were YAP phase. On the other hand, only, YAG phase was present in SiO2-contaminated Y2O3-doped alumina samples. Presence of Si appeared to have facilitated the formation of the complex YAG –phase.


This paper is a literature review of current researches, which aims to measure and specify more specific properties of the current situation about the use of dialogue for conflict resolution in schools of secondary education. In today s society, conflicts are increasing between humans, due to the many differences between each of the people living in it. This fact is also transferred to schools where there are conflicts between students and students and between teachers and students, which harm the teaching / learning process. In this theoretical review, the dialogue to resolve the conflicts in schools is addressed, studying the different perspectives that the authors determine when using the dialogue as a tool to reduce the problems that occur in schools. In this work we want to clarify the importance of dialogue between people to prevent and resolve conflicts and differences between them.


The major cause of death in patients with diabetes mellitus is macrovascular disease, particularly coronary heart disease, stroke, and atherosclerosis of the lower extremities. Indeed, the incidence of these ischemic complications is 1.7 to 4 times greater in men with diabetes than in men without diabetes and is 2.7 to 6.4 times greater in women with diabetes than in women without diabetes [1]. The presence of diabetes even eliminates the usual protection from coronary disease that premenopausal women have compared with men of similar age. Diabetic persons of either sex have had a two- to four-fold increase in mortality in population studies done throughout the world [2]. The development of atherosclerosis is greatly accelerated in persons with diabetes [3]. The reasons for increased vascular disease in diabetic persons are not completely known, but certain risk factors are much more common in patients with diabetes, especially adult-onset diabetes (noninsulin-dependent diabetes mellitus). These risk factors include hypertension, hyperlipidemia, visceral obesity, and hyperinsulinemia and have been called the deadly quartet or syndrome x [4, 5]. Several approaches may be taken to the prevention of coronary disease and peripheral atherosclerosis in persons with diabetes. Better glucose control is certainly one answer, but it is sometimes difficult to achieve in the free-living, affluent, and sedentary U.S. population. Diet and drugs can be used to treat hypertension and hyperlipidemia. All of these measures are helpful but may not completely solve the problem of excessive vascular disease. When evidence showed that Greenland Eskimos, because of their high intake of n-3 fatty acids, had a much lower incidence of coronary disease than Danes [6, 7], a question was posed. Would these fatty acids, found in fish and seal in the Eskimo diet, prevent coronary disease in Western populations? These n-3 fatty acids are the very long chained and highly polyunsaturated fatty acids: eicosapentaenoic acid (20:5) and docosahexaenoic acid (22:6). They are present only in food from the oceans and fresh waters: fish, sea mammals, and shellfish. Many studies then appeared showing that fish and fish oil preparations had many diverse actions that could alleviate vascular disease [8, 9]. These included mild blood pressure reduction, definite hypolipidemic effects, an antithrombotic action (achieved by inhibiting thromboxane A2 synthesis in platelets), inhibition of cellular growth factors and monocyte migration, and enhancement of nitric oxide production by the endothelium. It seemed reasonable, then, that fish oil be used in patients with noninsulin-dependent and insulin-dependent diabetes mellitus. Glucose homeostasis was achieved with no problems when fish oil was used in persons with insulin-dependent diabetes mellitus [10, 11], and one study actually showed less microvascular albumin leakage in the kidney [11]. However, in some studies, fish oil given to overweight patients with noninsulin-dependent diabetes mellitus caused mild glucose intolerance compared with a control period [12, 13]. As Heine [13] has reviewed, these adverse effects occurred in short-term experiments that had insufficient diet and weight control when 15 g or more of fish oil (90 kcal) was added to the usual diet [13]. A more recent study comparing fish oil and olive oil (15 g given randomly over 12 months) showed no difference in glucose homeostasis in persons who received fish oil compared with controls according to five criteria: fasting glucose level, hemoglobin A1c level, plasma and urinary C-peptide levels, and 24-hour urinary glucose excretion [14]. At the same time, plasma triglyceride and very-low-density lipoprotein (VLDL) levels markedly decreased during the fish oil period. The randomized, double-blind, placebo-controlled approach taken by Toft and colleagues, whose results are published in this issue [15], has provided more evidence for the absence of a deleterious effect of fish oil on glucose metabolism. Toft and colleagues administered n-3 fatty acids in a fish oil concentrate to 78 obese volunteers who had essential hypertension. Four 1-g fish oil capsules provided both eicosapentaenoic acid and docosahexaenoic acid in a total amount of 3.4 g/d. The placebo was 4 g of corn oil, which contained linoleic acid, an n-6 polyunsaturated fatty acid. After 16 weeks, fish oil had reduced the mean systolic blood pressure by 4.4 mm Hg and the mean diastolic blood pressure by 3.2 mm Hg. This mild hypotensive effect is similar to that shown in many other studies [8]. Fish oil did not alter glucose control, even in persons with mild glucose intolerance. The tests used were extensive: an oral glucose tolerance test, a hyperglycemic clamp technique, and a euglycemic hyperinsulinemic clamp technique. These tests measured insulin sensitivity and first- and second-phase insulin release. At the same time, a mild hypolipidemic effect occurred, and plasma triglyceride and VLDL levels decreased significantly. The high-density lipoprotein cholesterol level was also higher in the fish oil group than in the corn oil group. The plasma cholesterol and low-density lipoprotein levels did not differ between the fish oil and corn oil groups. The hypotriglyceridemic effects of fish oil, which have been so universally observed, result from a decrease in triglyceride synthesis in the liver and from an increase in the removal of triglyceride from the blood. This has been documented in several studies done in humans and animals [8, 16]. Because of these actions, fish oil has been useful in the treatment of hypertriglyceridemic patients [16, 17], especially those with the types of hyperlipidemia (V, IV, and IIb) so common in diabetic persons. Both the epidemiologic evidence and the results of a subsequent clinical trial done in the United Kingdom suggest that two to three fish meals per week might provide considerable protection against coronary disease [8, 18]. The clinical trial of n-3 fatty acids involved several thousand men who had recovered from myocardial infarction. The men who ate fish at least twice a week for 2 years had a 29% reduction in total mortality, largely because they had fewer deaths from coronary disease [18]. Persons who could not eat fish were given three fish oil capsules per day to supply the desired amount of n-3 fatty acids. Practical advice for the patient with diabetes would be that he or she should consume fish (prepared by poaching, grilling, baking, or broiling) two to three times per week. If eating fish is not possible, the consumption of two to three fish oil capsules (1 g each) per day would provide the equivalent amounts of eicosapentaenoic acid and docosahexaenoic acid. Because the study by Toft and colleagues [15] indicates both that fish oil has no harmful effects on glucose tolerance and that it has beneficial effects on blood pressure and plasma lipid levels, fish or fish oil might now be considered useful in the prevention of vascular disease in patients with diabetes.


PurposeThis study examined the relationship between adult respondents' COVID-19 risk perception and its impact on changes in eating habits, physical activity, alcohol consumption, and smoking.Design/methodology/approachA cross-sectional online questionnaire was used to collect data during the first wave of the pandemic, in the European spring and summer of 2020. Kruskal–Wallis and Pearson chi-squared tests were used to determine the associations between the consumers' COVID-19 risk perception and the respondents' country of origin. The respondents were primarily university employees and students from four European countries (the Czech Republic, France, the United Kingdom, and Italy).FindingsThe study showed significant changes in lifestyle behaviours of the respondents during the COVID-19 pandemic compared with the pre-outbreak period. Approximately half of all respondents reported a decrease in alcohol consumption, smoking, and physical activity, while eating habits among European consumers showed trends towards both healthier and less healthy dietary patterns. The most significant changes were recorded in reducing alcohol consumption, smoking, and physical activity among almost half of the respondents. Positive COVID-19 test experience, age, and country of the respondents had a negative influence, whereas healthy food consumption and alcohol consumption had a positive influence on the COVID-19 related risk perception.Originality/valueThe fear of the COVID-19 outbreak together with the restrictions imposed by national governments in response to the pandemic fundamentally affected the respondents' lifestyles. Understanding these changes can help establish interventions to alleviate the adoption of negative lifestyles and attitudes in subsequent waves of the COVID-19 pandemic or other similar situations.


Transient bubble formation experiments are investigated on polysilicon micro-resisters having dimensions of 95 μm in length, 10 μm or 5 μm in width, and 0.5 μm in thickness. Micro resisters act as both resistive heating sources and temperature transducers simultaneously to measure the transient temperature responses beneath the thermal bubbles. The micro bubble nucleation processes can be classified into three groups depending on the levels of the input current. When the input current level is low, no bubble is nucleated. In the middle range of the input current, a single spherical bubble is nucleated with a waiting period up to 2 sec while the wall temperature can drop up to 8°C depending on the magnitude of the input current. After the formation of a thermal bubble, the resister temperature rises and reaches a steady state eventually. The bubble growth rate is found proportional to the square root of time that is similar to the heat diffusion controlled model as proposed in the macro scale boiling experiments. In the group of high input current, a single bubble is nucleated immediately after the current is applied


We show that a universe dominated by cold dark matter fails to reproduce the rotation curves of dark matter dominated galaxies, one of the key problems that it was designed to resolve. We perform numerical simulations of the formation of dark matter haloes, each containing ≳106 particles and resolved to 0.003 times the virial radius, allowing an accurate comparison with rotation curve data. A good fit to both Galactic and cluster-sized haloes can be achieved using the density profile ρ(r)∝[(rrs)1.5(1+(rrs)1.5)]−1, where rs is a scale radius. This profile has a steeper asymptotic slope, ρ(r)∝r−1.5, and a sharper turn-over than found by lower resolution studies. The central structure of relaxed haloes that form within a hierarchical universe has a remarkably small scatter. We compare the results with a sample of dark matter dominated, low surface brightness (LSB) galaxies with circular velocities in the range 100–300 km s−1. The rotation curves of discs within cold dark matter haloes rise too steeply to match these data, which require a constant mass density in the central regions. The effects of Ωmass and Λ cannot reconcile the cold dark matter (CDM) model with data – even if we leave the concentration as a free parameter, we are unable to reproduce the observations with such a steep central density profile. It is important to confirm these results using stellar rather than H i rotation curves for LSB galaxies. We test the effects of introducing a cut-off in the power spectrum that may occur in a universe dominated by warm dark matter. In this case, haloes form by a monolithic collapse but the final density profile barely changes, demonstrating that the merger history does not play a role in determining the halo structure.

This paper proposes a new test for verifying the mean-variance efficiency of household portfolios. Unlike the standard statistics, the test takes account of two additional aspects: 1) wealth consists of real estate, held in fixed proportions in the short term, as well as financial assets, and 2) it is not possible to assume short positions in several financial assets. Performing the test on Italian households' portfolios as they appear in the SHIW 2000 survey, and treating housing as a fixed asset, we obtain an efficiency much more widespread than with common tests, revealing how inaccurate the standard theory is.

ABSTRACT A three-stage failure process divides a product's life into three stages: normal, minor defective and severe defective stages. Under the condition-based renewable warranty policy, inspections are carried out to check which stage the product is in. Condition-based activities, such as shorting inspection intervals, preventive replacement and failure replacement, are carried out properly. From a manufacturer's perspective, the inspection interval is optimized by minimizing the expected cost rate per unit time over the whole warranty coverage. For comparison, the expected cost rate per unit time for warranty models without inspections and with fixed interval inspections are also derived. Numerical examples show that condition-based renewable warranty policy replacement policy can reduce the manufacturer's warranty cost significantly.

【Objective 】To optimize the technical measures to improve maize haploid induced rates.【Method】Effects of five factors,including parent genotypes,selection of germplasm and generations,environments,pollination period,parts of maize ear on the rates of maize haploid were conducted in the field from 2011 to 2012.【Result and conclusion】The haploid induced rates were different among different materials with the same factor and different among different factors with the same materials. The haploid induced rates in female parent genotypes were significantly different. There was no significant correlation between the crossing pattern and the induced rate. The optimal induced haploid generation of five germplasms was S1. Compared to Changchun,Sanya was more conducive to improve the induced rate of haploid. The haploid induced rate of early pollination maize was higher than that of the late ones. The haploid induced rate at the top of the maize ear was higher than that at the bottom.


Solution‐processed organic–inorganic lead halide perovskite solar cells (PSCs) are considered as one of the most promising photovoltaic technologies thanks to both high performance and low manufacturing cost. However, a key challenge of this technology is the lack of ambient stability over prolonged solar irradiation under continuous operating conditions. In fact, only a few studies (carried out in inert atmosphere) already approach the industrial standards. Here, it is shown how the introduction of MoS2 flakes as a hole transport interlayer in inverted planar PSCs results in a power conversion efficiency (PCE) of ≈17%, overcoming the one of the standard reference devices. Furthermore, this approach allows the realization of ultrastable PSCs, stressed in ambient conditions and working at continuous maximum power point. In particular, the photovoltaic performances of the proposed PSCs represent the current state‐of‐the‐art in terms of lifetime, retaining 80% of their initial performance after 568 h of continuous stress test, thus approaching the industrial stability standards. Moreover, it is further demonstrated the feasibility of this approach by fabricating large‐area PSCs (0.5 cm2 active area) with MoS2 as the interlayer. These large‐area PSCs show improved performance (i.e., PCE = 13.17%) when compared with the standard devices (PCE = 10.64%).


Bridge performance can often be expressed in a reliability format, typically as the probability of failure. Information about present and anticipated bridge reliabilities, in conjunction with decision models, provides a rational and powerful decision-making tool for the structural assessment of bridges. For assessment purposes, an updated reliability (after an inspection) may be used for comparative or relative risk purposes. This may include the prioritisation of risk management measures (risk ranking) for inspection, maintenance, repair or replacement. A risk-cost-benefit analysis may be used to quantify the expected cost of a decision. The present paper will present a broad overview of the concepts, methodology and immediate applications of risk-based assessments of bridges. In particular, two practical applications of reliability-based bridge assessment are considered. For example, a risk-cost-benefit analysis suggests that proof load testing may not be cost effective if the costs of bridge failure (unsuccessful test) and the test itself are considered.

The capacity for flight lends birds great mobility. They are capable of traveling great distances, sometimes at the global spatial scale, and use various resources over land, water, and in the air. During their journeys, their flight (or travel) direction, the timing of their departure, and their destinations may be affected by various weather conditions including rain, snow, horizontal wind direction and strength, and thermals. Birds also exhibit the capacity to make active use of such conditions for efficient, energy saving flight. To fully understand the spatiotemporal movement patterns of birds, it is essential to consider how weather conditions affect avian movements. Observing the movements of free-ranging birds has its limitations, thus in the past it has been challenging to obtain information on the spatio-temporal movements of subject species. However, recent advances in technology have allowed ornithologists to track birds with great accuracy by using animal-borne devices such as global positioning system data-loggers and Argos Platform Transmitter Terminals. Furthermore, various institutes now provide numerical and graphical weather data (sometimes for free). The time is ripe, therefore, for ornithologists to consider engaging in this area of study. Recent global climate change has been reported to alter atmospheric and weather conditions; in turn these changes will likely influence ongoing changes and/or affect the distribution and movement patterns of birds. From environmental and ecological perspectives, it is important to understand the current relationship between the effects of weather conditions and bird movements, allowing us to provide projections of the potential impacts of climate change on birds. The first paper, by Nourani et al., reviews the behavioral characteristics of migratory soaring birds at various spatial scales with regard to horizontal and vertical air movements. The authors discuss different aspects of the migratory behavior of soaring birds, addressing separately land birds and seabirds. In the second paper, Yamamoto et al. examine how wind conditions affected the foraging trip durations of tropical Brown Booby fledglings by direct observation of nest attendance and by monitoring their flight behavior at sea by means of attached video camera loggers. They found that the Brown Booby's aerodynamic performance is impaired by strong wind conditions. The third paper by Matsumoto et al. examined the sex-related differences in foraging behavior of a sexually size-dimorphic seabird, Streaked Shearwaters, and the effect of a windy strait confining their foraging movement. Their results imply there may be a trade-off between the cost of traveling with unfavorable winds and the energy intake at the studied sea area. The forth paper, by Yamaguchi et al., describes how the movement patterns of Rough-legged Buzzards in winter and spring match the spatial distribution of snow cover. In the fifth paper, Manda et al. introduce user-friendly atmospheric data for ornithological studies. This review should be extremely helpful for ornithologists just beginning research into this subject. We hope that this special feature will stimulate future research in the field of avian movement ecology especially among Asian ornithologists.


The two-dimensional(2D) irregular packing problem is a classical optimization problem with NP-Hard characteristics, which has high computational complexity. The traditional heuristic algorithm and meta heuristic algorithm are usually used to solve packing problems, which has low packing efficiency and high time cost. Inspired by reinforcement learning(RL) and combined with the characteristics of 2D irregular pieces packing, a novel method to solve multi-constraint packing problem based on reinforcement learning is proposed in this paper. A reinforcement learning model based on Monte- Carlo (MC) method and a reward mechanism based on packing height return are designed. Finally, an example is used to analyze the optimization effect of the algorithm. The experimental results show that the proposed method can quickly and efficiently realize the packing of 2D irregular pieces, and a better solution can be obtained in an acceptable time.


Abstract : At the recent World Economic Forum held in Davos, Switzerland in January 2016 the overwhelming topic of discussion was the implications of the coming Fourth Industrial Revolution. One of the pillars of this revolution is what has become known as Big Data. Big Data is one of the fastest growing sectors of business and its users comprise everyone from United Parcel Services (UPS) to the Central Intelligence Agency (CIA). Silicon Valley startups continue to rake in millions of government and private investment dollars in the hopes that Big Data will continue to expand both the financial and informational return it is already providing. Edward Snowden's revelations of the National Security Agency (NSA) spy programs in 2013 gave the world its first real glimpse into the Big Data programs that were already in use by intelligence agencies, such as the NSA facial recognition database (footnote 1). Big Data use has also grown within the military structure in areas such as ground force operations and cyber warfare. Where Big Data has yet to make major inroads is in the arena of Air Power. Three scenarios will be considered to show the potential impacts Big Data could have on air power. Integrated properly into Air Operations as a decision aid and analysis tool, Big Data could be a tremendous aid for every warfighter - from the tactical level to commanders faced with complex strategic decisions.


The molecular structure of 2,4-di-tert-butyl-eta4-1,3-diphosphacyclobutadiene tin has been determined in the gas phase by electron diffraction using both the DYNAMITE and SARACEN methods. The suitability of many different theoretical methods for the calculation of structures of half-sandwich main-group metal complexes has been investigated, and, by comparison of the results with the experimental structures, suggestions have been made as to the most suitable methods for this class of compound.


A study was made of the effect of carbon, manganese, oxygen, palladium, and sulfur on the structure and fabricability of iron-35 wt.% chronium-1 wt.% yttrium alloy. Using a vacuum-induction melting technique each of the additives except oxygen was introduced to 1-lb remelts of a single 15-lb master alloy. The master alloy and remelts were made under similar melting, pouring, and casting conditions. Oxygen was introduced as Fe/sub 2/0/sub 2/ by inertelectrode arc melting to avoid extraneous, uncontrolled contamination stemming from crucible contact. Photomicrographs were prepared of as-cast metal illustrating structural variations. Ingots obtained were fabricated to 0.050-in. sheet at 2000 deg F to compare fabrication characteristics with those of the control ingot containing no additives. As a qualitative measure of metal soundness and ductility, a portion of each of the 0.050-in. sheets was further reduced at room temperatare to 3-mil foil. During melting at 2900 to 3000 deg F under controlled conditions, the amount of yttrium present in the charge was reduced roughly 50% by reaction with the alumina crucible. Sulfide, added as FeS, and oxide additions also lowered the amount of yttrium retained in ingots. The maximum amount of sulfur retained in an alloy of nominal composition iron-35 wt.%more » chromium--1 wt.% yttrium--500 ppm sulfur was found to be about 80 ppm, and an alloy containing this amount of sulfur seemed to show slightly improved fabrication characteristics. None of the impurities investigated affected the fabrication characteristics or the quality of the finished product sufficiently to be considered detrimental from this point of view. (auth)« less

For a latch-type sense amplifier in SOI SRAM,a pair of small discharging FETs are employed to bring the bodies of cross-coupled sensing devices to ground rail dynamically.This dynamic body discharge technique eliminates body potential mismatches of PD SOI CMOS devices,achieving repeatable low threshold voltage and fast SRAM access time.


Ukraine remains one of the leaders in the global ranking of morbidity and mortality from tuberculosis (TB) and, according to WHO, ranks 5th in the world and 2nd in Europe according to these indicators.
Objective — to analyze the regional features of the epidemiology of tuberculosis among children in the Chernivtsi region.
Materials and methods. The medical records of all pediatric patients with newly diagnosed TB for the period from January 2020 to December 2022 in the Chernivtsi Regional Clinical TB Dispensary were analyzed. Statistical processing of the data obtained during the research was carried out using the IBM SPSS Statistics v. 26.0 program.
Results and discussion. An analysis of the dynamics by years, when Ukraine was in lockdown due to COVID-19, revealed an increase in the incidence of TB among children under the age of 14 — by 2.7 times compared to 2021 and almost 8 times compared to 2020. 2 cases (25 %) of extrapulmonary tuberculosis, one of which (meningoencephalitis) had an unfavorable prognosis and resulted in death. Indicators of the tuberculosis situation in the Chernivtsi Region in the age group of 15—17 years showed an increase in TB in the percentage ratio of almost 2 times, with an even gender distribution (50 % each) compared to 2020 and 2021.
Conclusions. In Bukovina, for the period from 2020 to 2022, increase in the incidence of tuberculosis among children (almost in 2 times) was registered. In 2022, in 100 % of cases, TB was detected during referral, and in children living in rural areas, the majority were girls (62.5 %). In 87.5 % of cases, the diagnosis was confirmed bacterioscopically, in 50 % of children the presence of contact with a tuberculosis source was determined, in 12.5 % there was no BCG vaccination, in 25 % of children MDR-TB was registered.

For an electrochemical system with a nonvanishing relaxation time we obtain a generalized Warburg impedance from a hyperbolic diffusion equation. The generalized Warburg impedance determined in this way presents a slight positive curvature in the complex plane with smaller imaginary value at high frequencies.


Papular urticaria (PU) is a clinical entity where various stages of bite reactions occur simultaneously on an individual who has been exposed to biting arthro pods for prolonged periods. PU is usually inflicted by fleas and midges, but sometimes by biting mites. The mite Cheyletus malaccensis is a predator of domestic mites and is found occasionally in homes, where its presence is usually regarded as innocent because it may contribute to the control of the house dust mite population. Unlike its counterpart Cheyletiella, a docu mented inflicter of bite reactions associated with pets, Cheyletus is not known to cause any problems in Britain, although there are reports to this effect from Japan. The present paper describes a case of papular bite reactions which implicates Cheyletus. Criteria for the diagnosis of PU and control measures for Cheyletus are discussed.


In a former paper (" Phil. Trans.," P a rt'll, 1859) the authors had given the actual weights, and the percentage proportion in the entire body, of the individual organs, and of certain more arbitrarily separated parts, of 326 animals—oxen, sheep, and pigs—in different conditions as to age, maturity, fatness, &c. They called particular attention to the wide difference in the proportion by weight of the stomachs and intestines in the three descriptions of animal; the proportion of stomach and contents being very much the highest in oxen, considerably less in sheep, and little more than one-tenth as much in pigs as in oxen.


An examination was made of the heart rate responses during aversive classical conditioning of 5- to 6-week-old Labrador puppies exposed to restricted maternal uterine blood supply during gestation. The direction of the heart rate responses of the treated puppies was consistently decelerative, whereas nontreated controls showed both decelerations and accelerations. The absence of accelerative heart rate changes, combined with the observed depression of base level heart rate and attenuated emotional behavior in the experimental animals relative to controls suggests that uterine blood supply insufficiency may have impaired normal autonomic development in utero.


The Genocide Prevention Task Force believes that early prevention is not only the preferred course of action in strategic, resource, and moral terms; we also believe that engaging early can successfully obviate the need for a much more difficult crisis response at a later stage. Early prevention, however, is not easy. Building sustainable peace in fragile societies requires serious long-term investment. The U.S. government will need to increase resources, boost capacities, and exercise leadership to make prevention a priority. Because we cannot be certain where the next genocide will take place, the United States must be prepared to engage effectively in many complex situations simultaneously.


mRNA of Flammulina velutipes was extracted with Quick Prep mRNA Purification Kit, after synthesis of double-strand cDNA molecules using Time Saver cDNA Synthesis Kit, EcoRⅠ/NotⅠadaptors were added to the end of ds cDNA, phosphorylated by T4 polynucleoted kinase. Then the cDNA was ligated with λZAP Express Predigested Vector and packaged to transfect E.Coli XL1-Blue MRF? The results revealed that the tilter of the cDNA library was 4.0×106 pfu/ml, the amplified cDNA library is 2×1010 pfu/ml, the recombinant rate reached to 90%, and the length of inserts were between 0.3-3.5 kb. A candidate cDNA related with flammulin gene was screened by western blotting in situ.


Two perpendicular projections of rising bubbles were observed in counter-current downstream diverging flow. Evidently, the bubbles did not enter the boundary layer at the channel wall and a plug liquid flow assumption was acceptable in our experimental equipment. This confirmed that the experiment was appropriate for simulation of bubble rises in a quiescent liquid column. Recent data obtained by a high-speed camera permitted recording over a period of 60 s. Image analysis by a tailor-made program provided a time-series of quantities related to the position, size, and shape of bubbles. In addition to determination of the aspect ratio of the equivalent oblate ellipsoid, deviation from this shape was investigated in respect of the difference between the bubble's centre of mass and the geometrical centre of bubble projection. Autocorrelation of the data indicated that the bubble inclination oscillated harmonically with a frequency of 5–10 Hz; cross correlation showed that the horizontal shift of the centre of mass, as well as the horizontal velocity, increased with increasing bubble inclination, and the vertical shift of the centre of mass increased with an increases in the absolute value of the bubble inclination. There is no significant phase shift in the oscillation of these quantities. The bulky bottom side of the bubbles is in accordance with the model of bubble oscillation induced by instability of the equilibrium of gravity and surface tension forces. The oscillation frequency dependence on surface forces (Eötvös number) is evident, while viscosity does not play a significant role in low-viscosity liquids. Therefore, vortex-shedding is more likely to be an effect of the oscillation and not its cause.


This article examines whether EU merger control rules should be recalibrated to address concerns said to arise from acquisitions of innovative start-ups by established digital platforms – commonly referred to as 'killer' or 'nascent' acquisitions. It assesses various proposals designed to remedy two failings: a perceived failure to review anti-competitive transactions due to inadequate jurisdictional thresholds and a perceived failure to detect competition problems during the merger review process. It argues that, given the large number of transactions already subject to merger control, any expansion of existing rules should occur only where there is clear evidence of a significant enforcement gap. In the view of the authors, there is no persuasive evidence that a material number of anti-competitive digital acquisitions are escaping antitrust scrutiny, that the analytical framework applied by the European Commission should be significantly changed, or that the methodological tools employed to review concentrations are unfit for purpose. The authors therefore disfavour wide-ranging changes to the EU's rules and instead propose a series of incremental improvements to ensure that EU merger enforcement is tailored to the digital age.

We have become accustomed to the fuels and goods provided by "the complete barrel of oil", and it may seem difficult at first to find suitable replacements. Yet most of these products can be made from coal (peat, lignite), biomass, or even from nuclear energy using processes known at present. In particular methanol is an environmentally attractive fuel, which leads to many other products including petrol. For less critical applications, slurry fuels offer particular advantages for storage and transport. In redesigning our society around synthetic fuels, it is desirable to match the scale of production to various primary energy sources being used. A number of factors are discussed in this paper, which will determine the optimum size of synthtic fuel plant. /TRRL/

The reliability of an IoT system is determined by the values of quality of service parameters (QoS) and the security of the users. Taking into account the increasing usage of IoT and its resource-constrained nature it is sometimes difficult to provide security to the users and also maintain the QoS of the networks. In this paper, we propose a routing algorithm, Sidechai based Energy Efficient Routing (SCEER) that provides security using sidechain and uses trust-based routing for the selection of appropriate routes. The performance of the networks has been studied in the presence of masquerading attacks, flooding, and Sybil attack in different scenarios. The algorithm has been implemented for a network that will be helpful for the patients to find the doctors and communicate with them to receive medical help.

The term agri-food research has become a convenient shorthand term to describe anexpansion of sociological interest over the last 20 or so years in the relationships between agricultural production and: increasingly industrialized networks of food production, processing, distribution and retailing; the development of transnationalized modes of regulation and governance; environmental discourse, policy and social movements; and competing understandings and uses of 'rural' space. This paper critically reviews two theoretical approaches that have challenged the dominant theoretical trends that have underpinned this reorientation of the 'rural' social research agenda actor-network theory and vertical analysis. It is argued that applications of both approaches have frequently failed to transcend the very shortcomings they identify in agri-food studies, and suggestions are made as to how production-consumption relationships may be more adequately theorized and investigated.


Objective: To describe how unbiased next generation sequencing (NGS) from cerebrospinal fluid (CSF) aided diagnosis in a patient with meningoencephalitis caused by a rare and difficult to diagnose infectious etiology.
Background: There are many potential infectious causes of meningoencephalitis, including bacterial, viral, fungal, mycobacterial, parasitic and amoebic pathogens, many of which can produce similar clinical pictures. Targeted infectious disease diagnosis based on cultures, serology, PCRs, and biopsy can be costly, time consuming, and error-prone.
Design/Methods: A 74 year-old woman presented with endophthalmitis and progressive neurological decline. Brain MRI revealed multiple ring-enhancing supra- and infratentorial lesions. CSF exam was notable for a mixed pleocytosis and low glucose; extensive CSF cultures and PCRs were negative. An initial brain biopsy was non-diagnostic, demonstrating only minimal astrogliosis. Days before the patient's death, she had a second brain biopsy and was also enrolled in a formal research protocol at our center in which RNA was extracted from her CSF and prepared for unbiased NGS on an Illumina HiSeq machine.
Results: After filtering out human sequences from the dataset, 119 sequence fragments (out of 20,000,000 total) aligned with 96-99[percnt] similarity to the three known genes for Balamuthia mandrillaris - a widespread amoeba and rare cause of meningoencephalitis with poor prognosis for recovery. These NGS results were consistent with the pathology from the second brain biopsy that demonstrated necrotizing vasculitis secondary to an amoebic infection. Using pathogen-specific polymerase chain reaction on DNA extracted from the formalin fixed paraffin embedded tissue and immunohistochemistry, the amoeba was ultimately confirmed to be Balamuthia mandrillaris
Conclusions: NGS of CSF represents a powerful neurodiagnostic tool with the potential for rapid and unbiased pathogen identification leading to early therapeutic targeting in patients with meningitis and encephalitis of unclear origin.

Construction of bridges with long continuous lengths is definitely a preferred option nowadays. Advantages are lesser number of joints, better riding quality and durability of deck and wearing coat. Longer continuous lengths require joints with more expansion and contraction capacities. The solution then rests at modular strip seal type of expansion joint. This type of joint essentially consists of required number of strip seals assembled together. Capacity of single strip is about 70 to 75mm. This is limited on account of damage caused to wheels of the vehicles if gap is more than 80mm. Therefore, the capacity of modular type of joint is always in multiples of 75mm. The assembly of the strip seals makes load transfer of this type of joint in a unique pattern. This is totally different than load transfer mechanism of single strip seal. If the connection details are not prepared with due consideration to the said transfer mechanism, the joint will invariably fail early during service. This paper highlights the load transfer mechanism of the modular joint and discusses the detailing of the deck slab for proper connection of the joint with it.


Abstract Application of a recursive subspace identification method to derive a state space model for a synchronous machine is described in this paper. Simulation studies show the effectiveness of such an algorithm to identify on-line a synchronous machine model over a wide range of operating conditions and disturbances. The model provides a foundation for further study on a MIMO adaptive power system stabilizer.
