Hilar cholangiocarcinoma (HCCa) is a biliary malignancy that seriously affects the survival of patients. Radical resection is the only cure method for patients to achieve long-term survival. However, due to the low rate of radical resection, its prognosis is poor. In this article, surgical treatment strategies of HCCa in the precision surgery era, 3D image evaluation in the curative resection, surgical procedure decision and the preservation of liver parenchyma in the hepatic resection are discussed combined with the research progress at home and abroad.

After circling Mars for more than 4 years—taking pictures and making measurements—NASA's Viking Orbiter 1 has almost reached the end of its mission.

The orbiter has used nearly all the attitude control gas that keeps its solar panels pointed to the sun and its antenna aimed at the earth. When the gas is exhausted controllers at the Jet Propulsion Laboratory in Pasadena, California, will send radio commands to the spacecraft, ordering it to cease operating, thus ending its long and productive mission. It was originally expected that the gas would be exhausted by July 23±1 week; however, as of August 1 the spacecraft was still in orbit. NASA plans to terminate the mission August 15, even if the orbiter is still functioning at that time. Meanwhile, on the surface of Mars, Viking Lander 1 is programed to operate unattended through 1990, perhaps to be extended to 1994.


The benefits of using recycled and secondary aggregates (RSA) in road maintenance are considered. There are established practices for improving materials resource efficiency, including the use of RSA in fills, capping layers, sub-base, pipebedding, asphalt and concrete. The most popular forms of using recycled materials in highways applications are in and under bituminous pavements, footways and cycle paths. WRAP's Quality-Protocol provides a uniform quality control mechanism for users of RSA. Recent highway maintenance projects that used recycled aggregates include an 8km stretch of the A38 between Exeter and Plymouth and the A34/M4 junction. Incinerator bottom ash, recycled track ballast and recycled glass have been used in asphalt and blast-furnace and steel slag have been used as a hydraulically bound material in the construction of a canal towpath. The cost savings associated with RSA are discussed. WRAP is encouraging further use of RSA in highways applications through Recycled Roads workshops. Guidance is also available through WRAP'S AggRegain website.


ABSTRACT Deception is a phenomenon found within the practice of psychology. Beyond malingering, there are other reasons for people to lie within legal contexts. Therapists who work in legal contexts may be presented with deception within various aspects of practice. Previous research has indicated that non-forensic therapists held a number of inaccurate beliefs about indicators of deception and negative attitudes toward clients who lie. The current study was designed to explore if therapists within forensic settings held any advantages regarding beliefs about indicators of deception and to explore their attitudes toward clients who lie. We found that therapists who work within legal contexts demonstrate a lie bias, hold numerous inaccurate beliefs about indicators of deception, and possess negative attitudes about client's who lie. Interestingly, we found that therapists in legal settings endorsed two prosocial attitudes toward clients who lie finding them less lazy and less weak. Implications for research and practice are discussed.


We present the results of a two‐dimensional simulation of the amplification of an ambipolar current flow in a four‐terminal crystalline silicon device by charge induced into this flow from an insulated gate electrode. We show that although a bipolar current flow in a crystalline device can indeed be modulated by a gate field, the magnitude of this modulation is less than in amorphous silicon double‐injection field‐effect transistors. Our proposed structure also has an interesting feature in that the gate field redistributes the current flow between its terminals.


The testes had been removed when my attention was called to them by Mrs. Harnly. The two on the right side were entirely separate. The left two had a 10 mm. connection. The anterio: pair were the larger, the right one more elongated and oval, a little longer but narrower than the leaft, 34 mm. by 22 mm. The left was 30 mm. by 23 mm. The posterior right, 25 by 17 mm. and the left, by 23 mmi. by 17 mm. In section they are alike with normal testis struct,rye. Each testis had its own epididymus and vas deferans.

Three 1-D reduced molybdenum(V) phosphates, [Ni(OH)2][Na2(H2O)3]2{Ni[(MoO2)6(OH)3(HPO4)3(PO4)]2} · 2C6H14N2 · 2H3O · 5H2O (1), [Ni(H2O)2][K(H2O)5]2{Ni[(MoO2)6(OH)3(HPO4)3(PO4)]2} · 2C6H14N2 · 2H3O · 4H2O (2), and [Cu(H2O)2][Na(H2O)5]2{Cu[(MoO2)6(OH)3(HPO4)3(PO4)]2} · 2C6H14N2 · 2H3O · 4H2O (3), have been hydrothermally synthesized and structurally characterized by single-crystal X-ray diffraction. The crystallographic analysis reveals that 1 is based on {Ni[Mo6O12(OH)3(HPO4)3(PO4)]2} clusters connected through {[Ni(OH)2][Na2(H2O)3]2} pentanuclear mixed-metal cluster units to yield unusual 1-D chains along the c-axis, which further form 3-D supramolecular networks via hydrogen-bonding. Compounds 2 and 3 are heterogeneous isostructural compounds. Both are built from M[Mo6P4]2 (M = Ni or Cu) blocks as the structural motif combined with [MO4(H2O)2] (M = Ni or Cu) octahedra to form 1-D chains, where M[Mo6P4]2 (M = Ni or Cu) is bonded by [M′(H2O)5] (M′ = K or Na). Furthermore, bulk carbon paste electrode modified with 1 (1-CPE) displays good electrocatalytic activity toward reduction of nitrite or bromate.

Voltage sensitive dyes permit the measurement of biomembrane electrical activity where microelectrode measurements are unsuitable or inadequate. This laboratory has developed 2 class of such dyes as well as some new optical methods for mapping membrane potential in single cells. One class of compounds consists of amphiphilic membrane staining dyes containing a putative electrochromic chromophore aligned perpendicular to the membrane/aqueous interface. We have used these dyes to map the membrane potential along the surface of single cells with high resolution dual wavelength ratiometric imaging microscopy techniques. We have found intrinsic regional variations in the electrical properties of cell membranes. Adding chirality produces compounds that display remarkable efficiencies for second harmonic generation. Further, the second harmonic signal can be generated from a dye-stained membrane and is modulatable by changing the membrane voltage. This can form the basis for measurements of membrane electrophysiology at high 3D resolution with infrared light. A second class of dyes are membrane-permeant cations which act as Nernstian indicators. We have developed calibration methods which allow the use of these compounds to quantitate the membrane potential of individual mitochondria from confocal or widefield images of living cells.


Objective To probe into the effect of Kaisailu on urinary retention induced by intra-vertebral canal anesthesia.Methods One hundred and eight patients with urinary retention induced by intra-vertebral canal anesthesia were randomized into two groups equally,those in singular number as Kaisailu group and those in even number as the conventional group,with lower urinary tract obstruction,barrier at language and diseases of urinary system excluded.Results The total effectiveness rate reached 90.7% in the Kaisailu group and that in the conventional group 66.7%,with significant difference by 2 test(P0.01).The curative effects between the groups at the time spans of 10~30 min and 30~60 min were significantly different by Chi-squared test(2=11.642,P=0.003),indicating the effect in Kaisailu group was obviously better than that in the conventional group.On the other hand,the observation for the 56 urinary retention patients operated on in different approaches but treated with Kaisailu showed no statistical significance(P0.05),indicating Kaisailu had nothing to do with operational approaches in releasing urinary retention.Conclusion Kaisailu is effective,acceptable and simple in treating urinary retention,without side effects.


Objective To investigate hepatic parenchyma and kidney cortex's gray-scale ratio as a new index in evaluating hepatic fibrosis degree.Methods Sixty patients with hepatic fibrosis verified by liver biopsy and 40 normal individuals used as controls were scanned with Acuson Sequoia 512 with the same set-up of all the parameters.The hepatic-right kidney section was selected for offline analysis.The gray-scale value of near-area hepatic,mid-area hepatic,far-area hepatic parenchyma and right kidney cortex were measured by histogram of Photoshop software.The gray-scale ratio of hepatic parenchyma to kidney cortex was calculated and compared with the hepatic firbrosis degree.Results With development of hepatic fibrosis,the ratio of hepatic and kidney gray-scale value was increased.The results between control and experimental groups were significant(P<0.01).Conclusions Hepatic and kidney gray-scale ratio obtained from gray scale ultrasound was rarely affected by individual conditions of acoustic windows.It could be used as a new index for diagnosing of hePatic fibrosis and evaluating its therapeutic effects.

Key words:

Lightning is an inevitable natural phenomenon that causes damage to wind turbines both mechanical and electronic damage. Damage caused by overcurrent which is not immediately discharged to the ground then induces mechanical and electrical equipment. To do the analysis, simple modeling is needed so that the capability of lightning protection on the wind turbine can be determined, both already installed and to be installed. Simple modeling includes down conductor on the blade, sliding contact, spark gap, down conductor on the tower, and grounding. From the results of modeling that has been simulated using ATP Draw 3.5p10 indicates that the wind turbine which has a lightning protection system that uses down conductors on the tower is sufficient to secure the wind turbine from the risk of lightning strikes.


«Poetry must be music» (Umberto Saba): «fictio rhetorica in musica posita» (Dante). Cesare Brandi tells about the musical constitution of logos (discourse); and I tell about the logical constitution of music. Inger Christensen (1935-2009), Danish poetess, and Francesco Pennisi (1934-2000), Sicilian composer of the same age, dedicate their last works to butterflies. Systemic poetry, strictly bound, and free, rhapsodic music. Visible butterflies and sound butterflies: described in words, translated in music. Butterfly wings, sonorous colours, light filigrees, diaphanous bright watercolours are all Pennisi's creatures. Timbre is their privileged sound dimension. Last works, in limine mortis (on the threshold of death). What does death have to do with butterflies? Gotthold Ephraim Lessing explains that in his book Wie die Alten den Tod gebildet (1769) – How the Ancients Portrayed Death: as an overturned torch that dies down; and the soul is a butterfly that flies up from the deceased body. Angels too are butterflies: «… we are worms / born to form the angelic butterfly» (Dante). In 2008 Eben Alexander, an american brain surgeon, had a near-death-experience; in 2012 he told it in a book: after falling "into the dark… he found himself in a new world… surrounded by millions of butterflies".


An easily constructed differential radiometer is described which can be calibrated analytically from its geometric and physical parameters. An estimated 3% accuracy is achieved using common handbook values for the physical parameters, and the accuracy of the calibration is confirmed by experiment. The instrument measures net thermal radiation exchanged between surfaces near normal room temperature. It responds quickly to changes in incident flux and reaches equilibrium within about 1 min. It is sufficiently stable and rugged to be considered for student experiments and for demonstration lecture work. A number of elementary experiments are described which use the radiometer to demonstrate the behavior of long wavelength infrared radiation and to determine its interaction with materials.


Abstract This paper will study tourism as a site of citizenship formation with a particular focus on the arrangements and lived practices of citizenship in the Finnish Youth Organization and in a sub-section of Northern Ostrobothnian Travel Club between 1965 and 1985. From the perspective of the model of citizenship in Finland, modern mass tourism was not unproblematic and it was uniquely incorporated in the program and activities of the Finnish Youth Organization, underlining the wider social and civic utility of tourism. In this paper, the examination of archive materials from this particular historical period will provide a nuanced understanding of the mutual formation of citizenship and tourism at multiple geographical scales and insight into how the model of citizenship has been of great importance for mobile people in many ways.


Summary The recognition of alcoholic hepatic injury is diff icult because of both long clinical-biological latency of hepatopathy and the fact that alcohol consumption is recognized in less that half of cases. Performed re searches proved the value and utility of complex of tests for detecting of persons with a lcoholic intoxication. The evaluation of clinical syndromes at patients with alcoholic di sease of liver revealed the presence more frequently of hepatomegaly, icteric syndrome and portal hypertension, unlike to the patients with chronic viral hepatitis, at who m anifestations of neuro-asthenic syndrome prevailed. Clinical perturbations are more severe in chronic mixed hepatitis (viral and alcoholic) versus alcoholic and viral he patitis taken apart. The essential immunological modifications are characterized by ri se of IgA at patients with alcoholic intoxication and chronic hepatitis and alcoholic li ver cirrhosis and by rise of IgG at patients with chronic viral hepatitis. In chronic h epatitis and liver cirrhosis by alcoholic/viral etiology in association with chroni c alcoholic intoxication, significant rise of γ-GT, carbohydrate-deficient transferrin (CDT), alco hol dehydrogenase (ADH) and glutamate dehydrogenase (GDH) were discovered, versus liver pathology by viral etiology without alcoholic intoxication.


This paper studies information disclosure in innovation contests. We analyze a two-agent winner-takes-all contest in which each agent decides when to stop a privately observed search for innovations. Each agent makes a one-time submission of her best discovery to the organizer. The contest ends when both submissions are made, and the agent with the best innovation wins. We find that the organizer prefers revealing information on a submitted innovation upon receiving it to concealing it until the end not only because the former policy elicits a higher expected revenue but also because it is more efficient. Any hidden equal sharing rule is outcome equivalent to the winner-takes-all contest with information concealment.


Aluminum nitride was bonded with a titanium foil at 1400 °C for up to 1 h in Ar. The AlN/Ti interfacial reactions were investigated using analytical electron microscopy. Reaction layers, consisting of δ-TiN, τ_2-Ti_2AlN, γ-TiAl, α_2-Ti_3Al, a two-phase region (α_2-Ti_3Al + α-Ti), and α-Ti (Al, N) solid solution, were observed after annealing at 1400 °C for 0.1 h. Among these phases, the α_2-Ti_3Al and (α_2-Ti_3Al + α-Ti) were formed during cooling. Further diffusion of N atoms into the reaction zone precipitates a chopped fiber-like α_2-Ti_2AlN in the matrix of γ-TiAl, with [110]_γ−TiAl//[11^¯_20]_τ2−Ti2AlN and (1^¯_1^¯_1)_γ−TiAl//(1^¯_10^¯_3)_τ2−Ti2AlN, by substituting N atoms for one-half Al atoms after annealing at 1400 °C for 1 h. The released Al atoms, due to the precipitation of τ_2-Ti_2AlN, resulted in an ordered Al-rich γ-TiAl or Ti_3Al_5. Furthermore, the α-Ti (Al, N) was nitridized into a lamellar layer (δ-TiN + α-Ti) with [110]_δ−TiN//[11^¯_20]_α−Ti and (111)_δ−TiN//(0001)_α−Ti.


This paper proposes a multi-segment sliding mode (MSSMC) method for the planar switched reluctance motor (PSRM) developed in the laboratory to achieve precision positioning. The mechanical structure, the mathematic model and the control strategy are first given. Based on the mathematic model, the MSSMC strategy is then designed, which consists of an acceleration segment, a deceleration segment, and a positioning segment. Additionally, the stability analysis is discussed for the closed-loop system with the designed MSSMC strategy. Simulation is carried out based on MATLAB/Simulink. Compared to the conventional sliding mode control (SMC), the MSSMC is capable of weakening and better steady-state and dynamic performances were achieved. The effectiveness of the proposed MSSMC method is verified through simulation.


BY FRED SLUNECKA & DONNA FARRIS Mr. Slunecka is regional president and chief executive and Ms. Farris is writer and editor, marketing, Avera McKennan Hospital & University Health Center, Sioux Fallls, S.D. yUasK s costs escalate and insurance reimburse/ ^k ments lag, hospitals and patients alike are if»i Jk*. asking the same question: "Will health care be accessible and affordable in the future?" For health care administrators, a moral imperative exists to do all that's within our power to ensure affordable health care for the future. One solution we can all pursue within our individual organizations is to streamline processes and eliminate waste. As The Joint Commission relates, it has become common wisdom that an estimated 30 to 40 cents of every health care dollar is spent on waste — that is, on non value-added activities. While American industry has achieved a 3 percent productivity improvement every year since 1980, health care has lost productivity of 2 percent per year during that same period. No industry in the world can operate this way indefinitely. We haven't done anything positive for patients if we perform a world-class surgery on him or her, yet send them home to bankruptcy. It's absolutely essential that we are efficient with our patients' resources while giving them a great result. We can do no less. Avera McKennan has found a workable solution in implementing the techniques and principles of the Toyota Production System, known as LEAN. Since beginning LEAN projects in 2004, we've saved millions of dollars in construction costs, human resources and supply expense. We've taken a step further by helping other health care organizations realize the same successes through AveraOpEx, a collaboration with OpEx Inc., the consulting firm leading us through our LEAN implementations. Although LEAN principles have their origin in manufacturing, unique opportunities for health care organizations exist today. American health care is under constant pressures in terms of reimbursement. Government and insurance companies want to pay us less, while, at the same time, patients are demanding more. The only way we can meet patient demands under increasing cost constraints is to make more efficient use of our resources. LEAN has given us the tools needed to handle reduced reimbursements, provide outstanding care and maintain a solid bottom line for the institution. We've put LEAN principles to work throughout our hospital from our women's center, hospital nursing units and emergency department to the pharmacy, patient financial services and surgery. LEAN is not a "project of the month" as hospitals are so prone to adopt. We have every intention of continuing these projects until LEAN is


An experiment was carried out for two years in a greenhouse to study the effect of fungicides treatment on the germination of seeds of Sao Paulo cotton varieties, IAC 13-1 and IAC 17. Treated seeds were stored in uncontrolled conditions and germination was tested yearly. For each variety, the following treatments were applied: 1) PCNB + thiram, 2) Benomyl, 3) Check (mechanically delinted seed), 4) Acid delinted seed (D.A.), 5) D.A. + PCNB + thiram, 6) Metallic mercury. For treatments 1, 2 and 6 mechanically delinted seeds were used. Germination tests were carried out, in a randomized block design with three replications, by using fifty seeds in each experimental plot. Results were avaliated through an emergence index (%) and a resistance index (%) and showed the following: 1) The fungicide metallic mercury, PCNB + thiram, and Benomyl, had a significant effect on germination seven months after treatment, that persisted after sixteen months, except for Benomyl treatment. 2) The acid delinted seeds showed a decrease in germination at the sixteen months test. However, the negative effect of this treatment was adding PCNB + thiram.


Trade is the most important integration link in the overall world production. After the Second World War it induced the establishment of economic integrations. In the last three decades international trade has been more dynamic than the growth of the world production. The data show that the commodity trade is the strongest component of the world purchase and sale, although the international trade in services has grown a bit faster than the commodity trade. However, the share of services in the world trade does not exceed 20 per cent. International trade has most developed among developed countries, keeping up the mutual development of foreign direct investments and know-how and technology transfer. The empirical research shows that apart from the benefits gained by capitalisation of comparative advantages the trade growth is also influenced by benefits resulting from the impact of the economy of scale, competition and spreading of knowledge. Reduction of tariff and elimination of non-tariff barriers constantly opens new opportunities to benefit from international trade in commodities and services. Commodity trade of OECD countries confirms that the volume of trade does not depend only on liberalisation of tariff and non-tariff barriers, but growth to a certain degree reflects the size of the country, geographic elements and transport costs. Therefore, the empirical works predominantly analyse the power of trade as an indicator of the manifested commodity trade, embracing the characteristics such as competition pressures, but not including some deeper political meaning. The previously mentioned factor is significant, since given the policy and competition small countries are naturally more dependent on foreign trade, although competition pressures among big countries largely result from competition inside themselves. A significant change in the trade structure has been recorded in the period of over two years. At first, intra-industrial trade became equal to traditional inter- industrial production, and afterwards it has even exceeded it. For a long time the factors of foreign trade growth have been disputable. The works of Baier and Berstrand show that income growth and reduction of customs produce the main impact on foreign trade growth. In their opinion liberalisation of trade within GATT and WTO is one of the main driving forces in international trade. Reduction of trade costs also produces some impact on foreign trade growth, while approximation of incomes is less significant. Badlinger and Breuss have explored the elements that in the last four decades of the last century made an impact on faster growth of inter-trade of EU-15 member countries. They have estimated the relative impact of the income growth, income equalisation as well reduction of tariffs and trade costs on the intra-trade of EU-15 member countries. The results show that the income growth increases by 70 per cent the intra-trade of these countries. Also, the European integration and liberalisation of GATT and WTO increase by 25 per cent the commodity intra-trade of EU-15.


Purpose

The purpose of this paper is to explore the impact working in a therapeutic community (TC) has on staff practice and personal development.

Design/methodology/approach

Eight female members of staff who work in the TC participated in semi-structured interviews. Interviews were recorded and transcribed. Thematic analysis was used.

Findings

The findings of this paper show three superordinate themes: confidence gained within TC; the staff impact of the intensity of TC; and staff value for specific TC principles.

Research limitations/implications

Limitations include researcher bias as both authors work in the TC and/or in the service. Reasonable adjustments were made in order to account for this.

Practical implications

Implications for future research include understanding and supporting the needs of staff and further exploration of the impact of staff working within TCs for people diagnosable with emotionally unstable personality disorders.

Originality/value

The research was carried out at one of the longest running TCs for people with emotional instability in the country. It offers a unique opportunity to garner the views of staff members with up to 27 years of experience. Findings may be of value to practitioners, administrators, policy makers and researchers interested in therapeutic communities.


In Present scenario there is a need for the classification of prawn species with more accuracy. Recognition of an image is a rapid, economic, consistent, objective check and evaluation technique. Researchers had been doing research in this area for so long in the recent years due to deformation, noise, segmentation and obstruction of objects in digital images. Pattern identification can perform many functions in an aquatic processing line: sorting by species, by size, by gender, by visual quality attributes and automated portioning. Histogram of an image is a chart that shows the division of the different intensities in an image . This paper proposes a method of classifying prawn species based on the analysis of the Histogram values. In this work, three different penaeid prawn species include genus Penaeus monodon, Penaeus Indicus and Vannamei. The features of these prawn species are to be compared and to identify to which category it is related. Designing an automatic prawn species recognition system is necessary and most useful as it can perform effective and speedy recognition of prawns. Keywordsimage processing, pattern identification, penaeid prawn, Histogram values, species.


LabVIEW is a graphical programming language, used in many research fields for designing communication algorithms and simulating traditional as well as real time signals. Arduino kit can be interfaced with LabVIEW for a large number of applications. In this article, a project based on temperature sensor using Arduino Uno and LabVIEW is implemented. We have used LM35 temperature sensor whose output voltage varies in linear proportion to the temperature in centigrade. Thus, providing us an advantage over other sensors to measure the temperature conveniently in degree Celsius. The LabVIEW 2012 provides a simple interface between temperature sensor and Arduino Uno to read output voltage where LabVIEW further plots the measured temperature data obtained in real time in the graphical form.


By Michelle Zhang @michelle05155 Crime on campus is generally low; however, issues such as drug abuse and theft continue to persist, with theft being the most common campus crime at 261 incidents reported so far this year, according to the University of Texas Police Department. Gregory Gymnasium, Creekside Dormitory and the Perry-Castañeda Library top the list for locations with the highest reported theft-related incidents in 2016, according to UTPD. "Kids go play basketball, put their stuff in a locker, don't lock it, come back, and they're missing stuff," said UTPD crime analyst Ellis Eaton. Hot spots tend to be areas where personal belongings such as laptops, wallets or bags are left behind. Unattended devices are a big draw to the PCL for criminals seeking to pawn the latest iPhone or Macbook, Eaton said. Biochemistry junior Jess Hetton said she tends to leave her backpack and other items on their own when she studies. "I wouldn't think [theft] would be in the library," Hetton said. "I always leave my stuff laying around and it doesn't get stolen ... I guess it's a bit surprising." To prevent people from stealing valuables out in the open, UTPD officers periodically check up on students studying at the PCL. If they notice a laptop or phone left unattended, the officer will write a warning, letting the owner know that their items could have been stolen. Creekside Dormitory, located near the northeastern corner of campus, The Homelessness Outreach Street Team, an Austin Police Department program that helps the homeless population in the downtown and West Campus areas, was approved a one-year extension by City Council on Oct. 1 after a four-month pilot program. The team aims to address homelessness by working on the street, identifying homeless people in need, providing timely intervention and matching them with resources such as housing and mental health services before they get into a state of crisis or crime. The team is comprised of two APD officers, three case workers from Austin Travis County Integral Care and one paramedic from the community health program. "We basically go out into the community and interact with homeless people, trying to encourage them to engage in services," said Shelly Borton, an APD officer who works full time for the HOST program. "Our ultimate goal is to get them to complete an assessment for housing. We address mental health issues, we address employment issues. We try to provide them with assistance for getting identifications. Some people are just looking for bus tickets to go back to where they came from." HOST Austin was modeled after similar initiatives in surrounding cities, such as the Homeless Outreach


From 50 psychology students, homogeneous samples of handwriting were obtained and a standardized personality questionnaire was applied. 10 components were scored for the scripts and the questionnaire consisted of 11 components. Components of scripts and scores on the questionnaire were the predictors and second-year grade point averages in psychology provided the criterion. A higher multiple correlation was obtained for graphology than for scores on the personality questionnaire.


The purpose of this study is to find out the reflection of legislation and practical samples of democracy education in school education of Turkish Education. Method of this study can be defined field study. For this purpose especially objectives, rules and principles in legislation was examined then did observations in schools and try to find out how the practical applications reflected in democracy education in schools. Results; although there are some expressions to carry out democracy education in legislation part of the system, democracy education does not achieve in desired level in practically. The situation of using the classical teacher approach in class management gives some hints to us about the why democracy education was not desired functionality in our schools and classes. The most critical suggestions that reached in this study to settle the democracy in education is "at first school managers and teachers are benefited from the lifelong learning possibilities to be internalized and for making their lifestyle of democracy culture but so that we get desired level of democracy education in education".


With the approach of globalization commercial time,the slogan of "education industrialization" once as an extraordinary fad repeatedly referred to mediums.As a fallen education,it was a sagacious choice to reform that conforms to the times.However,the "industrialization" of education led to the "commercialization" of education.In the seductive sound of the consumer culture,the humanistic care seemingly had faded from the memory of Chinese higher education,but humanity of higher education is a development trend of the world higher education.Chinese higher education will realize the value of the humanistic care only on the base of respecting the specialty choice of students and the personality development of students.


A nonvolatile (NV) field-programmable gate array (FPGA) is quite attractive hardware platform for an internet of things (IoT) device in terms of reconfigurability and ultra-low-power standby power consumption. Moreover, the use of NV logic-in-memory (LIM) circuitry makes it possible to im-prove both area efficiency and energy efficiency. In this paper, some related topics about NV-FPGA, NV-LIM circuitry, and its application to the edge-AI accelerator are presented and its effectiveness is demonstrated.


Experimental measurements support a theoretical argument suggesting that if the collector current of a b.j.t. is plotted against collector-base voltage, for set values of base-emitter drive voltage, then the tangents to the characteristics at a given collector-base voltage, in the forward-active region, have a common intersection point on the collector-base voltage axis. The usefulness of this parameter, designated the early-intercept voltage, in the analysis of some linear i.e. schemes is mentioned.


tion. The state's long history of de jure discrimination was only modestly interrupted by Clayton's and Watt's election from the two majority-minority districts. The remedy of majority-minority districts evolved during several decades of legislative and judicial implementation of the 1965 Voting Rights Act. The issue, taken up by the Supreme Court in Shaw v. Reno (1993) goes to the heart of the historical question of race in American politics. Are the distinguishing patterns of political participation by race something government should aim to eliminate, sustain, or do nothing about? Shaw provides an answer to the question. The Court's decision is a reaction to the gradual evolution, development, and expansion of legal concepts and strategies aimed at reducing racial discrimination in the electoral system. Structuring majority-minority districts, while not the only or best solution, comes to grips with the history of discrimination in American politics and attempts to rethink the fundamental issues of representation, equality, and fairness in the political system.

We investigate the possibility of self-similar pulse evolution in solid state lasers. Numerical simulations with realistic parameters for a Ti:sapphire laser indicate that pulse energies of up to 1 nJ should be possible.


Since 1980s, the United Nations has been advocating for the 'full participation and equality' of disabled people. 'Personal Assistance' is one key factor in bringing the idea of guaranteeing disabled people's rights into practice. Disabled people's needs for personal assistance are multi-dimensional, which include: daily life, education, employment, etc.. In Taiwan, however, there are services provided to 'care for' disabled people but not to support disabled people at work. In view of this, The Cultural and Educational Foundation for the Blind (CEFB) developed a pilot scheme which provided 'visual assistant service' for visually impaired persons. The aim of this study is to understand how visually impaired users experienced the service and how the service met the needs, as well as the views of the project workers and visual assistants. The main findings are: First, the 'visual assistant service' has improved visually impaired workers' sense of control at work, and reduced their enforced reliance on their informal support systems. Nevertheless, they have little control over the way the services were provided. In addition, the author suggests some points to improve in the future, regarding the dimensions of services provided, the monitor of the program, enhanced communication with employers and more efforts on job accommodation.


The quality of e-commerce website services must be considered because it affects the number of users who access the website and decide to buy on an e-commerce website. Shopee is one of the fast-growing e-commerce websites in Indonesia, YLKI received 101 complaints in online shopping including among them complaints from Shopee consumers. The purpose of this study is to analyze the quality of e-commerce website services based on the user's point of view and know the attributes that affect customer satisfaction on service quality based on E-Servqual dimensions, namely efficiency, availability, fulfillment, privacy, responsiveness, compensation and contacts using Zone of Tolerance methods. Data obtained from questionnaires using purposive sampling technique with the number of respondents as many as 100 respondents, then the results of the questionnaire were analyzed using the ZOT method to find out the quality of acceptable minimal services. The results of this study indicate that customers are not satisfied with the quality of service provided with priority improvements to the attributes of Shopee parties willing to bear all shipping costs in the event of a mechanism to replace goods due to Shopee's fault. Keywords: service quality, e-servqual, ZOT .


Objective To investigate the effects of dexmedetomidine on early postoperative cognitive dysfunction(POCD)in the elderly patients who underwent transurethrue resection of the prostate with general anesthesia.Methods Eighty patients(65-80years)and scheduled for elective transurethrue resection of prostate were randomly divided into two groups:40patients received intravenous injection of dexmedetomidine 0.5μg/kg (group D)and 40 patients received same volume of normal saline(group C)in fifteen minutes before the induction.MAP and HR were recorded before infusion of dexmedetomidine(T0),intubation(T1),beginning of the surgery(T2) and 30min after surgery(T3).The time of operation,extubation awakening and drugs dosage were recorded.Cognitive function was assessed on 1 day before operation and on the 3th day after operation using mini mental state examination(MMSE).The adverse reactions such as nausea and vomit were recorded.Results There was no difference in the time of operation,extubation,awakening,drugs dosage and the incidence of the adverse reactions.Compared with group C,MAP at T1,T2in group D were significantly increased(P0.05).MMSE scores on the 3th day after operation were lower than 1day before in both groups,and group D was higher than group C(P0.05).The incidence of POCD in group D was lower than in group C(P0.05).Conclusion Preoperative administration of dexmedetomidine(0.5μg/kg)can decrease the incidence of POCD in the elderly patients undergoing transurethrue resection of prostate.

The invention discloses a magneto-resistor integrated chip for a current sensor. The magneto-resistor integrated chip comprises 4N (N=1, 2, 3, 4...) chip units of the same structure; each chip unit is of a multi-layer film structure and comprises a compensating lead wire layer, a magneto-resistor element and at least one soft magnetic layer; an insulating layer is arranged in the gaps between the compensating lead wire layer, the magneto-resistor element and the soft magnetic layer; the shape of the insulating layer is matched with those of the compensating lead wire layer, the magneto-resistor element and the soft magnetic layer; the compensating lead wire layers of the 4N chip units are formed integrally; the compensating lead wire layers are U-shaped in a plane parallel to the substrate; and the magneto-resistor elements of the 4N chip units are the same and are connected to form a bridge. The magneto-resistor integrated chip has the advantages that the size is reduced to millimeter magnitude from centimeter magnitude, the fabrication cost is obviously reduced, the consistency of the product is good and the anti-interference capability for the external magnetic fields is obviously enhanced.


Menformone and estrogen were obtained from the manufacturers. Ovarian hormone was extracted with ether from the urine of pregnant women. Ovariectomized mice were used in assaying the hormone. In order to secure very accurate measurements, women were placed on weighed diets (no breakfast) and allowed about the same amount of exercise each day and metabolism taken 15 hours after the last meal. The O2 and CO2 were determined by the apparatus described in J. Biol. Chem., 1928, lxxvii, 413, the nitrogen determined by micro-Kjeldahl, and, the basal metabolism calculated. By this means the Benedict-Roth-Collins apparatus was tested. The psycho-galvanic reflex, muscle tone, and blood pressure were measured as a check on the physiological state of the subjects. Half the women had basal metabolisms 15% below Aub-Dubois'standard, probably due to deficiency of iodine during childhood. In testing the effects of hormones, it was found that 1 mg. of thyroxine subcutaneously raised the basal metabolism of "normal" women 3% in 2 days and 5 mg. raised it 15% in 2 days. Injections of "menformon" and "estrogen" were made subcutaneously. On days of injection no food was taken and hence the physiological state may not have been considered absolutely constant. The basal metabolism of woman No. 1 was considered too variable for conclusions to be made and the study of her metabolism was discontinued. Women of small vital capacity had more regular breathing than women of large vital capacity. After injection of 2000-4000 mouse units of ovarian hormone it is excreted in the urine in about 6 hours. In the first woman the metabolism rose after injection of 300 mouse units and fell after 880 units. In the 2nd woman the metabolism fell after 1000 mouse units.


SiO2∕Si3N4∕SiO2 (ONO) stacks are used as trapping media in industrial semiconductor memories. This memory device uses deep traps in the silicon oxynitride interlayer between the silicon nitride layer and the top oxide. In this research, low-thermal budget (low temperature) ONO layers were designed suitable for integration into advanced scaled down semiconductor technologies. The alternative growing procedure included oxidation of silicon nitride surface in oxygen plasma. Low temperature oxidation of the silicon nitride layer in oxygen plasma allows incorporation of oxygen into the silicon nitride layer, thus forming a silicon oxynitride layer. The chemical composition of the silicon oxynitride interlayer was similar to the oxynitride of thermally grown ONO. The plasma procedure did not cause any surface roughening. The memory devices with the low-temperature-oxygen-plasma ONO stack showed similar performance to memories with standard high temperature ONO. ONO structures were characterized chemically and s...


Low-temperature microwave absorption measurements at 9.3 GHz in ceramic YBa/sub 2/Cu/sub 3/O/sub 7-//sub delta/ were made on the broad modulated signal observed after maximum flux had been trapped. Noise occurred on the extrema of this signal if the modulation frequency and amplitude were sufficiently high and the temperature was close to the lowest that could be attained when the limiting factor was the microwave heating of the sample. The source of the noise is proposed to be thermal instabilities, which produce small flux avalanches in the superconducting grains.

Aim: To determine the incidence of hypoxia, to identify the clinical value of pulse oximetry during unsedated endoscopy. Methods: A prospective study conducted at Al-Kuwait University Teaching Hospital, and Police Typical Hospital, Sana'a. Sixty eight consecutive patients underwent Upper gastrointestinal endoscopy (UGIE) were enrolled in the study. Arterial oxygen saturation, pulse rate and blood pressure were monitored with continuous pulse oximetry and automated blood pressure monitor before the procedure, at regular intervals during the procedure, during initial recovery and upto 10minutes after the procedure. We study the effect of risk factors on oxygen desaturation in unsedated upper endoscopy to determine whether or not pulseoximetry is useful. Results: Mean age of the patients was47.06±12.45 (53 men and 15 female). Mean endoscopic time was14.71±4.81 minutes (ranged from 10 to 38 minutes). Cardiopulmonary changes observed during the present study were transient and of no disastrous consequences. Mildoxygen desaturation was observed in13 patients (19.1%).Severe hypoxia (SaO<85%) was rare episode (1.47%).Three patients (4.4%) suffered significant decrease in oxygen desaturation and required oxygen supplementation. Mean oxygen saturation before the procedures, during insertion of the endoscope, during scoping, and after procedure were 95.65±2.58, 91.44±2.63, 92.43±2.65 and 94.25±2.44 respectively. Oxygen saturation decreased significantly during probe insertion, during scoping of endoscope, and after procedure as compared with baseline oxygen level (P<0.05). The changes in oxygen saturation were significant during endoscopic insertion in patients ≥50 years when compared to those <50 years (P<0.05). Conclusions: Mild hypoxemiais common adverse event during non-sedated endoscopic procedure and of no disastrous consequences. Furthermore, oxygen desaturation developed during the endoscope may have resulted in undetected hypoxemia with serious consequences. We recommend pulseoximetry monitoring in patients at risk for desaturation. Patients at risk are elderly and patients with respiratory diseases


The main objective of this study was to identify sources of high iron and zinc content in landraces and hulless barley grain to be used in developing new barley germplasm with improved value for human nutrition. A collection of 333 landraces from 34 countries was grown for three consecutive years at ICARDA's research station located near Tel Hadya, in Syria. In the third year, the collection was also planted at a second ICARDA research station, near Breda. The samples were analyzed at Waite Analytical Services, University of Adelaide, Australia. A spatial analysis was carried out using GENSTAT. The heritability of iron content in the grain was 0.589 in Breda and 0.562 in Tel Hadya; the heritability of zinc content was 0.639 and 0.605 in Breda and Tel Hadya, respectively. Six landraces were identified with consistently higher iron across environments, ranging from 38.8 to 51.6 ppm. Three of these entries also have high zinc content, ranging from 37.3 to 42.5 ppm. Moroccan landraces are a very promising source of high iron and zinc content in the grain. Ethiopian, Russian and Ecuadorian landraces also have a few promising sources. During 2007, ICARDA's micronutrient laboratory applied a dry-ashing method for the determination of iron and zinc content in hulless barley. A total of 1087 breeding lines were grown at Breda in 2005 and analyzed for iron and zinc. The iron content ranged from 22.6 to 36.7 ppm while zinc content ranged from 19.98 to 49.72 ppm. The variety Atahualpa confirmed its high iron and zinc content: it ranked first for iron and second for zinc (43.9 ppm). Both iron and zinc content were highly and positively correlated with protein content (0.56 and 0.74, respectively). The correlation coefficient between iron and zinc content was 0.64. Sample preparation for barley grain analysis is discussed for reducing contamination.


Editor COVID-19 is presenting the international surgical community with unique challenges. Whilst surgical intervention is being reserved for the most critical cases1, operating on patients who are COVID-19 positive poses an increased infection risk to surgical teams. Personal protective equipment (PPE) is being employed to reduce risk of transmission but this may rapidly become in shortage2. Telesurgery helps reduce the number of healthcare professionals required to be physically present during a procedure, which in turn decreases risk of viral transmission and consumption of PPE. We present the case of a COVID-19 positive patient who underwent urgent incision and drainage of an acute forearm collection at our institution with assistance from an augmented reality (AR) platform. A 59-year-old male patient was admitted with a persistent cough and fever of 39⋅2∘C. His extensive past medical history included diabetes mellitus, hypertension, hypothyroidism, chronic renal impairment and dyslipidemia. Given the history of being in contact with a COVID-19 patient during the previous week, IgG and IgM immunoassay testing for COVID-19 was performed and returned positive. During his hospital stay, the patient developed pain and swelling in the left antecubital fossa at the site of a previously inserted intravenous cannula and was diagnosed with superficial thrombophlebitis of the cephalic and basilic veins, confirmed on ultrasonography. He was treated conservatively initially; intravenous antibiotics were added when his condition failed to improve. However, over the following days, the swelling and erythema progressed to include the lower arm and anterior aspect of the proximal forearm. The patient was persistently febrile with rising inflammatory markers. Repeat ultrasonography revealed a multi-loculated subcutaneous collection in the left forearm with associated subcutaneous Fig. 1 Snapshot of the Proximie video feed showing the surgical field with a virtual hand cursor controlled remotely by a consultant to draw a suggested incision line using augmented reality tools


The application of standardization is a key factor in the development of agricultural products market. The agricultural products standard system is forming now, but the market is still in chaos. The reasons lie in the characters of agricultural products and incomplete of the inspection mechanism . To realize these and to utilize the inspection mechanism efficiently are very important in the course of agricultural products standardization.


A mathematical algorithm to describe DNA or RNA sequences of $N$ nucleotides by a string of $2N$ integers numbers is presented in the framework of the so called crystal basis model of the genetic code. The description allows to define a not trivial distance between two sequences and to perform the Discrete Fourier Transform on a sequence. Using the definition of distance the sequence of $\beta$-globin for Homo, Gallus and Opossum are compared. The Discrete Fourier Transform for some simple examples is computed.


Many research efforts for advanced Li-ion batteries have been made to design new material with large capacity and long cycle life, but little attention is paid to regulate the voltage platform until now. Though quite attractive for the binary Ge-based chalcogenides, challenge is that large potential gap as well as incongruous reaction kinetics is typically found between their conversion step (>1.6V) and alloying region (<0.4V). Herein, we propose an endogenetic structural design by grafting Sb2Te3 building block into layered GeTe to establish ternary Ge2Sb2Te5 compound which can effectively level such big potential gap. Turning from semiconductive GeTe into metallic conductive Ge2Sb2Te5, the reaction kinetics can be enhanced. The LixTe formation step in Ge2Sb2Te5 is found declined to 1.30V, and the enlistment of Sb (0.78V) bridges the conversion and alloying plateau, thus the incongruous reaction kinetics and large potential gap between conversion-alloying step can be alleviated. Furthermore, there is a spatially-confined and synergistic effect between Te, Sb, Ge component, conducting the LixTe and LixGe process in a more harmonious and gentle way. Therefore, Ge2Sb2Te5 exhibites much enhanced cyclability and rate performance, with 546mAh/g remained at 2000mA/g. This unique design strategy can be leveraged to manipulate the voltage profile of other compounds.


Selective hydrogenolysis of biomass-derived tetrahydrofurfuryl alcohol (THFA) to produce 1,5-pentanediol (1,5-PeD) is accomplished by a binary catalyst consisting of MoO3 and supported Rh nanoparticles; a 1,5-PeD selectivity up to 80% is achieved in the present work. Moreover, a very interesting phase-transfer behavior for MoO3 during the reaction is observed with the assistance of different characterization techniques. In this process, MoO3 dissolves partially in the liquid phase under the reaction conditions and is transformed into the soluble hydrogen molybdenum oxide bronzes (HxMoO3) in the presence of H2, which are recognized as the genuinely active sites for the C–O bond breaking of THFA. Density functional theory (DFT) calculations were then carried out to simulate the plausible mechanisms and highlight the role of Mo in the ring-opening process of THFA in more detail. We propose that the formation of 1,5-PeD takes place in a two consecutive reactions. THFA first undergoes acid-catalyzed ring-openi...


In the process of sheet metal bending, there is a large deviation between the value of sheet metal unfolding calculation by UG software and actual processing. In order to solve this problem, the method of unfolding calculation by UG software is analyzed and compared with the traditional calculation by manual compensation. The relationship between the neutral factor value K in unfolding calculation by UG software and the compensation factor value B in calculation by manual compensation is obtained through formula derivation. Thus, the purpose of automatic unfolding calculation by UG software instead of manual compensation calculation is realized.


Tie-point extraction is the key step of coregistration of multitemporal images. In this paper, Scale invariant feature transformation (SIFT) is applied to extract tie-points from multitemporal SAR images. A histogram-based preprocessing method and the optimization of SIFT parameters are proposed for increasing the number of correct tie-points. We explore the performance of SIFT algorithm on different topographic ENVISAT SAR images. The experimental results show that these methods are robust to speckle noise and can markedly improve the performance of SIFT on SAR images.


This study conducted one semester of empirical research about cooperative learning on the juniors majoring in chemistry in the Normal University.The result shows that between the two groups,there was a significant difference in the peer relationship and academic performance.Through their own experience,81.18% of the pre-service chemistry teachers took a positive attitude towards cooperative learning whereas 95.46% of them considered that this learning is very helpful for improving their teaching skills,and they are willing to use it in the future.


With the "route guidance" becoming noted as one of the solutions to the chronic traffic snarl in urban areas, network traffic information is provided in an active manner for guiding drivers to proper routes. It also goes without saying that the provision of traffic information may largely contribute to the success of the ITS (Intelligent Transport Systems) projects currently under way mainly in Japan, US, and Europe. It is, however, still only insufficiently known how a driver selects his or her link, using such provided traffic information, and what are the resulting effects on network traffic flows. Thus the objective of these studies was to, hitting upon a well-dispersed traffic flow, "understand what effects the provision of traffic information could bring to the dispersion of traffic flows". With such an objective in mind, simulation-modeling and simulation experiments were conducted for this understanding. At last it was found that the effect of provided information accompanied with popularization of in-vehicle units increases to a certain level of dissemination of the units, followed by reaching a plateau, without decreasing the effect. For the covering abstract see IRRD E102946.

Restoring economic growth in Europe using only monetary policy, even of the unconventional variety, appears more and more insufficient and in desperate need of a second or third leg. In a much debated speech at Jackson's Hole this summer, Mario Draghi recalled this difficult context in the fight against the risk of stagnation. (First paragraph)


Reactions in Ti/Si 3 N 4 and TiN/Si diffusion couples annealed in the temperature range of 1000-1200 o C were studied theoretically as well as experimentally with SEM/EPMA technique. Isothermal sections of the Ti-Si-N system were calculated using the most recent thermodynamic data. Calculations showed that TiN and Si react with each other and for Si 3 N 4 and TiSi 2 , parallel to the experimental studies. Correspondingly, results from the Ti/Si 3 N 4 couple were in good accordance with calculated phase equilibria


DESIGN AND APPLICATION OF ORGANIC ELECTRONIC MATERIALS: PENDANT TUNING IN POLYMERIC AND MOLECULAR SYSTEMS MAY 2015 JONATHAN TINKHAM, B.S., UNIVERSITY OF VERMONT PH.D, UNIVERSITY OF MASSACHUSETTS AMHERST Directed by: Professor Paul M. Lahti Designing and synthesizing materials for use in organic electronic materials requires fine control over their optical and electronic properties. Variations through substitution can be used to tune solubility and electronic properties, but this can result in degradation of other properties. Substitution with orthogonal pendant groups in both molecular and polymeric systems has the potential for allowing tunability while decreasing the perturbation of other desirable properties of the parent system. This idea was explored through experimental and computational work. Computational modeling was used to understand and predict the properties of molecular and polymeric systems to narrow the wide number of choices of possible materials. The ability to computationally predict not just molecular orbital energy levels, but other properties of the system such as UV-Vis transitions, unpaired spin-density, and changes in dipole moment is important not just for designing new materials, but in understanding how they work. This is accomplished in modeling a modular approach to tuning of frontier orbital energy levels. Newer strategies for predicting photovoltaic performance by analysis of the ground-to-excited state dipole moment change are also explored. A series of low-bandgap polymers absorbing at a bandgap of 1.7 eV, near the "ideal" bandgap of 1.5 eV, were prepared by copolymerizing an electron-donating and electronwithdrawing unit to yield a low-bandgap "push-pull" copolymer. The donor unit was designed to study the effect of pendant phenyl substitution. The resulting copolymers were


The theft-protection device comprises a first rod element which is preferably manufactured from cemented steel and forms at one of its ends a hook element which can be arranged on an operating pedal of a motor vehicle. At its other end, the first rod element forms a body which is likewise manufactured from strong metal material and to which a second rod element can be telescopically connected, which is likewise preferably manufactured from cemented steel. This element forms at its upper end an open ring for connection to the steering wheel of the motor vehicle and, at a lower end, it has a large number of annular grooves which are arranged at a distance from one another and make possible connection to the metal body. Also mounted inside the latter is an electronic alarm device which can be switched on if required and is suitable for establishing the presence of moving bodies inside the vehicle and triggering an acoustic alarm.


Abstract High-pressure liquid chromatography was used to separate the fluorescent adduct formed from the reaction of histamine with o-phthalaldehyde (OPT) from other biogenic amines in tissue, cerebrospinal fluid (CSF), sweat and urine samples. Using off-column derivatization and isocratic elution techniques fluorescent OPT adducts can be detected in the low picogram range. Perchloric acid extracts of tissue samples from Aplysia california and urine specimens collected from healthy adult males, including internal standard, were derivatized with OPT buffer, pH 9.5 and extracted with ethylacetate to increase sensitivity and stabilization of the fluorescent adduct prior to chromatography. Sweat and CSF samples were reacted with OPT buffer and aliquots of this mixture injected directly onto the chromatographic column (μBondapak CN) with methanol/0.08 mol/liter acetic acid (52/48 by volume) as the mobile phase. Assay of pooled urine containing added histamine (1 μg/ml) gave a with-in run coefficient of variati...

In this paper, the pressure of s195 diesel engine was forecast and analyzedthrough the equation of combustion established accordingly. And the result was evaluated by the test, which based on the different proportions of the diesel and bio-diesel fuel, then, the very inosculated result was received at last. And more, by measuring the content of soot and NOX, it was found that the waste let became better along with the increase of biodiesel, but was lower in dynamical nature. Through the synthesis value the content of biodiesel about 10% was the best.


Standard magnetic resonance imaging approaches offer high‐resolution but indirect measures of neural activity, limiting understanding of the physiological processes associated with imaging findings. Here, we used calibrated functional magnetic resonance imaging during the resting state to recover low‐frequency fluctuations of the cerebral metabolic rate of oxygen (CMRO2). We tested whether functional connections derived from these fluctuations exhibited organization properties similar to those established by previous standard functional and anatomical connectivity studies. Seventeen participants underwent 20 min of resting imaging during dual‐echo, pseudocontinuous arterial spin labeling, and blood‐oxygen‐level dependent (BOLD) signal acquisition. Participants also underwent a 10 min normocapnic and hypercapnic procedure. Brain‐wide, CMRO2 low‐frequency fluctuations were subjected to graph‐based and voxel‐wise functional connectivity analyses. Results demonstrated that connections derived from resting CMRO2 fluctuations exhibited complex, small‐world topological properties (i.e., high integration and segregation, cost efficiency) consistent with those observed in previous studies using functional and anatomical connectivity approaches. Voxel‐wise CMRO2 connectivity also exhibited spatial patterns consistent with four targeted resting‐state subnetworks: two association (i.e., frontoparietal and default mode) and two perceptual (i.e., auditory and occipital‐visual). These are the first findings to support the use of calibration‐derived CMRO2 low‐frequency fluctuations for detecting brain‐wide organizational properties typical of healthy participants. We discuss interpretations, advantages, and challenges in using calibration‐derived oxygen metabolism signals for examining the intrinsic organization of the human brain.


The exploration of arbuscular mycorrhiza fungi from sugarcane plantation in marginal land in South Sulawesi was carried out to find the source of inoculums showing effective infection. Soil samples were taken from four area with different characteristic of marginal land, namely land with low organic matter content, clay texture, limited irrigation, and undulating land. Mycorrhizae contained in the soil samples were then observed, and the spores obtained were used as the source of isolation by a single spore culture. The mycorrhizal spores were isolated by wet sieving and centrifugation method with 48% sucrose, which were observed under a compound microscope for spore details (100-1000x). Sugarcane root samples were taken to observe mycorrhizal infection in sugarcane root tissue by root staining method. The results of the study showed that the greatest diversity of mycorrhizal genera was found in soil samples of Jambua Block (Glomus, Gigaspora, and Sclerocistis) and AJ-5 Block area (Glomus, Acaulospora, and Sclerocistis). Single-spore isolates obtained were Glomus sp. and Acaulospora sp. Infection test result on four sugarcane varieties commonly grown in Takalar Sugar Factory showed that infectivity of mycorrhizal isolate of Acaulospora sp. was the highest (75%) and significantly different (LSD'test, p 0,05) compared to that of Glomus sp. (66%).


Hemophilia A is a hereditary bleeding disorder resulting from reduced factor FVIII activity. It occurred in 1/5000 male. Currently, the treatment option is with the factor FVIII replacement therapy. A long-acting recombinant monomeric FVIII-Fc fusion protein product (Eloctate®) has been approved in 2014 by the US FDA, it requires to infuse the drug for every 3 days or twice a week. There is a clinical need to develop longer half-life product to extend the treatment option to once a week infuse for hemophilia A patients. Recently, we have developed a dimeric recombinant factor VIII-Fc (drFVIII-Fc) fusion protein therapeutic candidate, which is entering the clinical development in China. To generate a longer half-life recombinant FVIII product, we have developed a PEGylation method to PEGylated this drFVIII-Fc fusion protein to PEGdrFVIII-Fc. We have analyzed and characterized the fusion protein by various analytic methods, as well as in vivo animal tests. It was shown that PEGdrFVIII-Fc fusion protein has been modified with about five Y type of 40kd PEG; the remaining activity is around 700 IU/mg, and the in vivo tests in cynomolgus monkey demonstrated that the fusion protein has a half-life of about 37 hours. The data also showed that there was no detectable affinity binding activity of vWF to a PEGdrFVIII-Fc fusion protein, as compared with the binding activity of 5.16X10-4M for the molecule of a drFVIII-Fc fusion protein. In conclusion, we are able to generate a PEGylated form of a drFVIII-Fc molecule with the relevant specific activity and has been shown the molecule with the prolonger half-life in the in vivo tests. The further biochemical analysis demonstrated PEGdrFVIII-Fc fusion protein with no detectable vWF binding activity, which might explain why its half-life is longer than vWF's ~15hours half-life in vivo. This molecule is likely to be used as a once-weekly treatment option for hemophilia A patients. Currently, we are in the development stage of an IND filing in China.

By taking Gangxi Block of Dagang Oilfield as an object of study, a quantitative interpretation model suitable to watered-out reservoir interpretation in the block is established, which combines conventional logging, induced polarization potential logging with complex resistivity logging on the basis of comprehensively analyzing the data of its geology, well logging, logs and formation testing. It is used for data processing for 24 wells with coincidence rate of 81.6%.


Excited states have been observed for the first time in the very neutron-deficient {sub 55}{sup 114}Cs{sub 59} nucleus. The assignment to {sup 114}Cs was made by detecting {gamma} rays in coincidence with evaporated charged particles and with recoiling evaporation residues. A rotational band has been observed up to spin 21({Dirac_h}/2{pi}) (tentatively 25({Dirac_h}/2{pi})). Excitation-energy systematics and a study of quasiparticle alignments suggest that the band is based on the {nu}(h{sub 11/2})x{pi}(h{sub 11/2}) configuration. Unlike bands based on this configuration in heavier cesium isotopes, only one signature partner is observed, and there is no evidence for signature inversion. These observations agree with theoretical calculations which predict that Coriolis-induced signature splitting should dominate at N=59.

Structure formation at small cosmological scales provides an important frontier for dark matter (DM) research. Scenarios with small DM particle masses, large momenta or hidden interactions tend to suppress the gravitational clustering at small scales. The details of this suppression depend on the DM particle nature, allowing for a direct link between DM models and astrophysical observations. However, most of the astrophysical constraints obtained so far refer to a very specific shape of the power suppression, corresponding to thermal warm dark matter (WDM), i.e., candidates with a Fermi-Dirac or Bose-Einstein momentum distribution. In this work we introduce a new analytical fitting formula for the power spectrum, which is simple yet flexible enough to reproduce the clustering signal of large classes of non-thermal DM models, which are not at all adequately described by the oversimplified notion of WDM . We show that the formula is able to fully cover the parameter space of sterile neutrinos (whether resonantly produced or from particle decay), mixed cold and warm models, fuzzy dark matter, as well as other models suggested by effective theory of structure formation (ETHOS). Based on this fitting formula, we perform a large suite of N-body simulations and we extract important nonlinear statistics, such as the matter power spectrum and the halo mass function. Finally, we present first preliminary astrophysical constraints, based on linear theory, from both the number of Milky Way satellites and the Lyman-α forest. This paper is a first step towards a general and comprehensive modeling of small-scale departures from the standard cold DM model.


The major reasons given for population planning are health, human rights, ecological balance and political economy of population size. Contraception, however, is an old subject and has been used since classical times. France showed the earliest widespread use of contraception in Europe in the nineteenth century with the goal of improvement of family status. The extension of birth control in the U.S. was promoted by feminists such as Goldmann and Sanger as a necessary part in the emancipation of woman. The eugenics philosophy of population bloomed in the 1920s and 1930s and led in part to the policies of Hitler. In the 1960s the demographic factors of population growth were given more consideration. In the mid 1960s ecologists explained population growth as a damaging force to the environment through its depletion of resources and pollution, and thus felt it must be limited on ecological grounds. This mixture of reasons for population planning has led to a decrease in humanitarian concerns and thus the health and welfare of clients is often not the prime concern in population programs.


Non-precious Fe/N/C catalysts have attracted increased attention due to their activity in oxygen reduction reaction (ORR). To promote the activity of this type of catalysts, we applied the electrochemical treatment of the Fe/N/C sample synthesized by using the known technique. We demonstrated that two-stage anodic-cathodic treatment of the Fe/N/C sample under the certain condition leads to increase the electrocatalytic activity toward the ORR of the starting catalyst. The results may open the opportunities in finding new ways of increasing the activity of Fe/N/C catalysts by using the electrochemical treatment.


The objective of this study was to describe an alternative technique to the Manchester procedure for uterine suspension of a uterus with an elongated cervix, which is applicable for patients undergoing laparoscopic repair of multiple pelvic floor defects.
This study consisted of a retrospective review of 2 patients who underwent vaginal trachelectomy combined with laparoscopic uterine suspension using a high uterosacral fixation technique.
Two patients with stage II prolapse of an elongated cervix, each of whom desired conservation of her uterus, underwent transvaginal partial trachelectomy combined with a laparoscopic suspension of the uterus using a high uterosacral fixation technique. They then underwent concomitant laparoscopic paravaginal repair, antiincontinence surgery, and posterior repair. No intraoperative complications were noted. The patients were discharged within 24 hours.
In patients undergoing laparoscopic repair of multiple pelvic floor defects, and who have protrusion of an elongated cervix, transvaginal partial trachelectomy combined with laparoscopic uterine suspension is a safe and effective alternative to the Manchester procedure.


With the rapid growth of Internet technologies, Internet of Things (IoT) devices have become widely required. A huge number of smart devices around the world containing sensors and actuators are collecting data and processing it to perform specific actions. As these services deployed via the Internet, it becomes an easy target to the vulnerabilities. The defenses against these threats need to maximize and ensure high security to maintain the confidentiality, availability, and integrity of IoT resources. Different techniques and approaches have been proposed and established to protect smart devices and data from attacks. This survey uses the five layers architecture to explore different types of threats and vulnerabilities at an individual layer of IoT architecture. It also reviews different types of techniques and, approaches and methods to secure IoT architecture.


Introduction: Fibrodysplasia (myositis) ossificans progressiva is a rare and very crippling form of disease characterized by great toe malformation and heterotopic bone formation. We herein report a case of fibrodysplasia ossificans progressiva in whom the onset of complaints was after 20 years of age which led physicians to confuse this case with ankylosing spondylitis.


ABSTRACT Many self-directed weight-loss interventions have been developed using a variety of delivery formats (e.g., internet and smartphone) and change techniques. Yet, little research has examined whether self-directed interventions can exclusively promote weight loss. MEDLINE, Embase, PsycINFO, CINAHL, and the Cochrane Library were systematically reviewed for randomised controlled trials evaluating self-directed interventions in relation to weight-loss outcomes in adults. Standardised mean differences (SMD) and 95% confidence intervals (CI) were calculated using a random effects model. Twenty-seven trials incorporating 36 comparisons met our inclusion criteria. Participants using self-directed interventions lost significantly more weight (MD = −1.56 kg, CI −2.25, −0.86 ranging from 0.6 to 5.3 kg) compared to those in the minimal intervention or no-treatment groups (3.1-month follow-up median). The majority of interventions were internet based (18 evaluations) and these were effective at 3 months (MD = −1.74 kg, CI −2.65, −0.82 ranging from 0.6 to 4.8 kg) (SMD = −0.48, 95% CI −0.72, −0.24, I2 = 82%; p < .0001; 16 evaluations) and 6 months follow-up (MD = −2.71 kg, CI −4.03, −1.39 ranging from 2.2 to 5.3 kg) (SMD = −0.59, 95% CI −0.99, −0.19, I2 = 76%; p = .004; 4 evaluations). Self-directed weight-loss interventions can generate modest weight loss for up to 6 months but may need to be supplemented by other interventions to achieve sustained and clinically meaningful weight loss.


The article reflects on some possible similarities and differences between Leibniz and Chomsky in relation to the mind/body relation, language, the method of work, meaning, thinking and the concept of innate. It emphasizes the notions of "innate" and "virtual" and raises the hypothesis that Leibniz's conception of "virtual" can be applied to the theory of Chomsky by considering three situations that are related to the degree of attention and ordering necessary for the actualization of the innate principles. Key words: Chomsky, innate, Leibniz, language, virtual.


P Alain Supiot has argued "the socio-economic regulatory model that had underpinned labour law since the beginning of the twentieth century is in the throes of a crisis".1 In Ireland, like most countries, this crisis can be attributed to the distinct "lack of fit" for traditional labour law to modern work relationships. Traditional tests used to determine employee status, and its concomitant protection, have been somewhat sidelined by modern hiring practices. There is little doubt that a change in hiring practices in Ireland is occurring at the time of writing and will continue to occur for some time to come. The incidence of Irish workers holding a contract of limited duration has risen from a low of 3.4 per cent of the total workforce in 2006 to 8.5 per cent in 2008.2 Such a startling increase has led to a "dualisation" of the workforce between what are commonly referred to as "typical" workers, those working under a traditional work relationship, and "atypical" workers, those working in a type of work relationship that does not conform to the traditional model.3 The problem that arises is that traditional labour law does not apply easily to, and consequently serves to marginalise, temporary workers, leaving them vulnerable to exploitation.4 For reasons of expediency this paper does not address the European Union approach to modern labour markets. However, since the official launch of the "flexicurity" agenda in November 20065 the concept of flexicurity is seen as the best response to changing global market conditions. Consequently, the European institutions are to the forefront in the "drive to make labour markets more flexible while at the same time

The invasions of Iraq and Afghanistan spurred a range of popular activity – from anti-war protests to war boosterism to veterans' advocacy – purporting to 'support the troops'. Non-governmental organizations (NGOs), from veterans' welfare organizations to anti-war groups, are crucial to this transformation of 'the troops' into a social cause and matter of collective concern. As such, this article proposes an initial qualification of NGO representative practices as a form of media genre, characterized by striking similarity in presentation, structure and, particularly, explicitly normative tone. A poststructural discursive approach is utilized to examine the implications of this genre for the production of subjectivities and power relations inherent to 'supporting the troops' via a structured analysis of the public-produced texts of a selection of typologically identified NGOs in the US and the UK. The article goes on to highlight the ways in which NGO representations counterintuitively objectify those they seek to support, while simultaneously limiting the political possibilities of supporters. Overall, it is argued that within the context of the liberal state, the representations of support produced across the advocacy spectrum work to not only depoliticize conflict but to 'apoliticize' support for the troops as a matter of morality.


"Soup" is one kind of common and important diet.In the course of its development,it has evolved the idea of "harmony" and become a metaphor of rich content in Chinese culture."Harmony" is not only a kind of philosophic idea but also the core of the theoretical system of traditional political ethnics.It has been deeply embedded in the culture character and human relation the Chinese nation and has great influence on them.The traditional idea of taking "harmony" as basic meaning and value pursuit is an important part of the Chinese culture and can become an important ideological resource for constructing a harmonious society.


Time resolved studies using femtosecond laser pulses at 800 nm illuminate the distinctions in the dynamics of ultrafast processing of dielectrics compared to semi-conductors and metals. Dielectric materials are strongly charged at the surface on the sub-ps time scale and undergo an impulsive Coulomb explosion prior to thermal ablation. Provided the laser pulse width remains in the ps or sub-ps time domain this effect can be exploited for processing. Otherwise, the high localization of energy accompanied by ultrafast laser micro structuring is of great advantage also for high quality processing of thin metallic or semi-conductive layers, where the surface charge is effectively quenched.

Scenarios for a manned mission to the Moon or Mars call for astronaut teams to be accompanied by semiautonomous robots. A prerequisite for human-robot interaction is the capability of successfully tracking humans and objects in the environment. In this paper we present a system for real-time visual object tracking in 2D images for mobile robotic systems. The proposed algorithm is able to specialize to individual objects and to adapt to substantial changes in illumination and object appearance during tracking. The algorithm is composed by two main blocks: a detector based on Histogram of Oriented Gradient (HOG) descriptors and linear Support Vector Machines (SVM), and a tracker which is implemented by an adaptive Rao-Blackwellised particle filter (RBPF). The SVM is re-trained online on new samples taken from previous predicted positions. We use the effective sample size to decide when the classifier needs to be re-trained. Position hypotheses for the tracked object are the result of a clustering procedure applied on the set of particles. The algorithm has been tested on challenging video sequences presenting strong changes in object appearance, illumination, and occlusion. Experimental tests show that the presented method is able to achieve near real-time performances with a precision of about 7 pixels on standard video sequences of dimensions 320 × 240.


Inconsiderable fraction of the hydrocarbon can be produced by the natural drive of the reservoir. Practical knowledge has proven that when the reservoir pressure is depleted, the recovery factor nearly reaches 20%. Some of heavy fluid reservoirs cannot be produced by all natural energy drivers. As a result, improved oil recovery is introduced as a strategy to increase oil recovery. Prior implementing an improved oil recovery process in a field, it is essential to investigate its potential for achievement. However, the objective of this project is to evaluate the improved oil recovery in a sandstone reservoir is considered in this study. GEM compositional reservoir simulator has been utilized, having injection and production wells. A model is developed to perform history matching with a field production data to verify the model results and to examine an improved oil recovery method on cumulative production and recovery factor. The results showed that the water flooding has insignificant impact on the cumulative oil production, while implementing horizontal production wells had improved and doubled the reservoir performance by a factor of 2 and reducing oil saturation from 80% to 30%.

Objective: to present a clinical case of endemic infection visceral form of New World leishmaniasis as a possible cause of fever of unknown origin in a young child. Materials and Methods. This article contains a description of a possible case of visceral New World leishmaniasis in a young child diagnosed ex juvantibus and considering staying in endemic area (Brazil). With the consent of the child's parents, we have used data from medical documentation (extracts from case histories, test results and instrumental studies) from the clinics of Ukraine (Dnipropetrovsk) and Turkey (Istanbul). Conclusions. All cases of fever of unknown origin, especially in patients with an indication of staying in the suband tropical regions, should be promptly examined for Leishmania (blood, sternal punctate) using microscopic, serological and molecular-biological methods. Negative test results should not preclude the diagnosis of endemic infection, if any other cause is not determined.

This research was carried out in the Municipal Public Company of the Camal of Quevedo and its main objective is the structuring mechanisms of prevention of occupational risks. Initially, the model matrix contained in the Colombian Technical Guide GTC 45 was used, this is a fundamental tool for the development of this research because it involves phases that involve criteria that allowed the technical identification of hazards, risk assessment and the establishment of intervention controls. As a result, the risk factor prevalence was: biomechanical, for which quantitative methods were applied for its evaluation, which were OWAS, RULA and the NIOSH equation; Physical, here it is necessary to know the levels of noise and labor illumination by calibrated measuring equipment and then be evaluated with national standards; Biological, in which by the nature of the process it is essential to maintain a permanent control, elaborating a cleaning and disinfection program. The information obtained served as a reference to conclude that the prevalence of the aforementioned risks represents a degree not acceptable to the health of the workers and that actions need to be taken, for which mechanisms were presented to reduce the gap that causes labor accidents.

The paper covers theoretical analysis of the existence conditions for sliding processes in electromechanical servo systems of optical complexes, based on coefficients of differential equations describing the systems. It is shown that these conditions may be formulated by frequency characteristics of dynamic elements of electromechanical complexes. The conditions of sliding based on servo drive frequency characteristics are obtained, and it is shown that these conditions are equivalent to the conditions of absolute stability of obtained equivalent circuits of servo drives with relay elements. With the help of the designed method the author has made suggestions on the synthesis of near-ideal sliding processes in electromechanical complexes described by high-order differential equations. The author assumes that sliding processes may be realized in electromechanical systems with asynchronous drives as well; the data of experiments proving these assumptions are given.
