In pH =2. 97,pH =6. 97 and pH =9. 98 type coal mine water and 5% NaCl solution,the performance of corrosion and abrasion of HVOF (high velocity oxygen fuel) spray 316L stainless steel coating on mine shaft steel guide surface were investigated. Corrosive potential and EIS (electrochemical impedance spectroscopy) of the coatings were measured by mean of the electrochemistry system,friction coefficient using the MM -2000 tester,oxidation damage based on the X-ray diffraction experiments,and wear appearance by SEM. The results show that corrosive potential of the 316L stainless steel coating increase 300 mV. The corrosive rate is controlled by ion diffuseness in 5% NaCl and pH =2. 97 solution,while by charge transfer in pH =6. 97 and pH =9. 98 solution. The X-ray diffraction results show also that 316L stainless steel powders are low oxidation in HVOF spray process and the spray coating contents are γ -(Fe,Ni)and γ -(Fe,Cr). The friction coefficient are decreased with load for the spray coating. The corrosive and abrasive surface appearant the micro adhesion wearing mechanism.


In this paper, the new method called second refinement of Jacobi (SRJ) method for solving linear system of equations is proposed. The method can be used to solve ODE and PDE problems where the problems are reduced to linear system of equations with coefficient matrices which are strictly diagonally dominant (SDD) or symmetric positive definite matrices (SPD) or M-matrices. In this case, our new method minimizes the number of iterations as well as spectral radius and increases rate of convergence. Few numerical examples are considered to show the efficiency of SRJ over Jacobi (J) and refinement of Jacobi (RJ) methods.


Changing the counter-anion in 2-pyridylmethyl imidazolium salts (Br, BF4, PF6, SbF6) causes their kinetic reaction products with IrH5(PPh3)2 to be switched from normal C-2 to abnormal C-5 binding.


At present, grinding mode is used for the finishing process of large cylindrical roller bearing flanges. However, because of low efficiency, large consumption of grinding wheel and grinding fluid, high costs, serious pollution of cutting waste fluid, and more importantly, easy to generate grinding burns and cracks defects, grinding machining has become a technical problem that troubles the economic and effective processing of large bearing ring flanges in the bearing industry. Therefore, the research on the hard turning technology for the finishing process of large cylindrical roller bearing flanges is carried out in the paper. The experiment investigations have shown that the finishing quality of large cylindrical roller bearing ring flanges can be better and more economically guaranteed by hard turning process.


Abstract : The ability to maintain and grow the inventory of Sea, Air, and Land (SEAL) operators depends on the ability of NSW to recruit high probability candidates effectively and increase the retention rates within the existing ranks of SEAL operators. Using data from the BUDs/Pride Database, this thesis draws on logistic multivariate regression models to test the theory that candidates with a prior strong social tie to NSW are more likely to complete the BUDs training successfully than those with no such tie. Geospatial mapping supplements this analysis by providing relatively easy to interpret visualizations of the recruit network. The combination of the logistic models and the geospatial interpretations of the data provide a clearer picture of the entire recruit network. Looking at the results of the logistic regression model, and the ordered logistic regression model, it can be seen that students with a strong tie, either to NSW or another special operations force within the U.S. military, are more likely than students without such a tie to make it through the training pipeline.


During a routine examination of impulse activity in efferent vagal fibres, it was noticed that many fibres showed a discharge coincident with inspiration. These fibres were traced to the recurrent laryngeal nerve. An investigation was made of impulse activity in fibre preparations of this nerve. In addition, electromyographic records were made of activity in the intrinsic muscles of the larynx. A summary of these findings was presented to the Physiological Society by Green & Neil in 1954.


Two-dimensional (2D) Dion-Jacobson (DJ) perovskite solar cells (PVSCs) with high PCE are currently predominately fabricated via a hot-casting process. While it is difficult to prepare high-quality perovskite film under mild conditions when the application of divalent ammonium. In this work, the morphology of the 2D DJ perovskite film was tuned with the aid of MASCN additive under room temperature spin-coating deposition conditions. The device with inverted planar structure presented a hero performance of JSC of 17.91 mA cm−2, Voc of 1.19 V, FF of 0.76 and PCE of 16.25%, which is the highest PCE ever reported for hot-casting free 2D DJ PVSCs.


The invention relates to a high-voltage DC quick circuit breaker and a power sub-module thereof. The high-voltage DC quick circuit breaker comprises a mechanical isolating switch, a main through-flow branch and a current transfer branch. A circuit which is formed through serially connecting the mechanical isolating switch and the main through-flow branch is parallelly connected with the current transfer branch. The current transfer branch is composed of a plurality of serially connected power sub-modules. Each power sub-module is a mixed sub-module and comprises the components of a pair of power transistors which are serially connected in a forward-and-reverse direction, a pair of power transistors which are parallelly connected in the forward-and-reverse direction, two voltage sharing resistors and a voltage sharing capacitor. Compared with a DC circuit breaker in which a fully controlled device or an H-bridge is used, the high-voltage DC quick circuit breaker is advantageous in that the number of serially connected modules is 1/3-1/2 of that of the previous DC circuit breaker, thereby greatly reducing size of the DC circuit breaker and reducing cost.

The definition of the inner scale for atmospheric turbulence is given. Methods of measuring inner scale are discussed and typical values are given. Innerscale effects on irra-diance covariance and log-amplitude covariance are discussed for both weak and strong scintillation. The covariance width is limited by the inner scale for saturated scintillation.


Steerable needles are capable of accurately targeting difficult-to-reach clinical sites in the body. By bending around sensitive anatomical structures, steerable needles have the potential to reduce the invasiveness of many medical procedures. However, inserting these needles with curved trajectories increases the risk of tissue damage due to perpendicular forces exerted on the surrounding tissue by the needle's shaft, potentially resulting in lateral shearing through tissue. Such forces can cause significant damage to surrounding tissue, negatively affecting patient outcomes. In this work, we derive a tissue and needle force model based on a Cosserat string formulation, which describes the normal forces and frictional forces along the shaft as a function of the planned needle path, friction model and parameters, and tip piercing force. We propose this new force model and associated cost function as a safer and more clinically relevant metric than those currently used in motion planning for steerable needles. We fit and validate our model through physical needle robot experiments in a gel phantom. We use this force model to define a bottleneck cost function for motion planning and evaluate it against the commonly used path-length cost function in hundreds of randomly generated 3-D environments. Plans generated with our force-based cost show a 62% reduction in the peak modeled tissue force with only a 0.07% increase in length on average compared to using the path-length cost in planning. Additionally, we demonstrate the ability to plan motions with our force-based cost function in a lung tumor biopsy scenario from a segmented computed tomography (CT) scan. By planning motions for the needle that aim to minimize the modeled needle-to-tissue force explicitly, our method plans needle paths that may reduce the risk of significant tissue damage while still reaching desired targets in the body.


The Integrated Plate Boundary Observatory Chile (IPOC) in northern Chile has been monitoring the largest seismic gap along the South American subduction zone for 10 years. When IPOC was initiated, it has been 130 years the last great earthquake in the region had occurred. And since then the Iquique gap had been accumulating a slip deficit along a >500 km segment of the plate boundary. Since IPOC's inception two large events, the 2007 M 7.7 Tocopilla and the M 8.1 2014 Iquique earthquakes, have broken parts of the gap. Both events were well recorded by IPOC, produce valuable data and advance our understanding of the subduction megathrust earthquake cycle. Last year, the Helmholtz Centre for Ocean Research Kiel (GEOMAR) has been extending IPOC with the GeoSEA ocean bottom observatory. In this ambitious project deformation will be measured where it cannot be picked up by land-based instruments, i. e. far offshore near the subduction trench. This will open the crucial updip section of the subduction plate boundary to research. IPOC has thus demonstrated the necessity of long-term monitoring to observe slow or rare events, but also that tenacity and patience pay off.


The liver and kidney of female Bandicota bengalensis and Tatera indica rats collected from Bathinda region of south west region of Punjab were used to investigate the toxic effects of these pesticides. Levels of total proteins decreased in all the rats collected from study area. Activity levels of different OS parameters: catalase (CAT), superoxide dismutase (SOD), glutathione transferase (GST), glutathione reductase (GR) and glutathione peroxidise (GPx) were differentially altered and the product of oxidation namely, malondialdehyde increased in liver (11.05±0.18, 9.02±0.26 in control rats increased to 11.60±0.10, 9.43±2.58 in study area B. bengalensis and T. indica rats respectively) and kidney (10.03±0.44, 8.68±0.24 in control rats increased to 10.18±0.72, 8.92±4.34 in study area B. bengalensis and T. indica rats respectively) of rats collected from study area as compared to control rats. Histomorphological studies further revealed number of abnormalities as infiltration, vacuolization, enlarged sinusoids and necrosis in liver of Bathinda rats, while renal histo architecture of kidney showed high degeneration of glomeruli. The results infer that environmental contaminants mainly pesticides leads to number of pathophysiological conditions in the liver and kidney and for altering antioxidant defence system in rats inhabiting south- west region of Punjab.

Objective:  To define the clinical characteristics of patients hospitalized with COVID-19 in ICU and ward and to evaluate the significance of liver function test results. A new disease caused by SARS-CoV-2 has been devastating the world affecting millions of patients worldwide and leading the significant mortality and morbidity.
Material and Methods: The demographic features of a cohort of 125 hospitalized patients between March 2020 and May 2020 were recorded. The clinical characteristics, laboratory findings, and mortality rates were analyzed.
Results: A total of 125 patients hospitalized for COVID-19 diagnosis where 113 (90.4%) were followed-up in the ward and 12 (9.6%) were in ICU were included in the study. The mean age of the patients was 44.05±16.95 and 88 (70.4%) of the patients were male. The most common symptoms were in the following order: cough in 80 patients (64%), dyspnea in 40 (32%) and fever in 33 (26.4%). The leukocyte and neutrophil counts were significantly higher in ICU patients with COVID-19 compared to patients in the ward (p=0.002, p<0.05; respectively). The CRP and D-Dimer levels were found elevated in ICU patients with COVID-19 than in the ward (p<0.05; p<0.05, respectively). The AST level of patients with COVID-19 in ICU was significantly heightened than patients in the ward.
Conclusion: The present study revealed that patients with elevated AST level were at great risk of progressing to severe disease those require close monitoring.


Various types of benzophenone ketyls were prepared by the reaction with alkali, alkaline earth, and rare earth metals and their ESR spectra were studied. In the aliphatic ether solvents DME, THF, and Me-THF, it was found that the monomer ketyl radicals are ion paired and that the spectra show lines due to splittings by protons and metal. Assignments of coupling constants for various benzophenone ketyls gave complete agreement between experimental spectra and predicted ones in intensity ratio. Discussion is also given on splitting mechanism for C13.

Background:  Hobnail hemangioma (HH) is a rare subtype of hemangioma that shares the morphological feature of hobnail endothelia with retiform hemangioendothelioma (RHE) and has to be considered in the differential diagnosis of Kaposi sarcoma. Since DNA of the human herpesvirus type 8 (HHV‐8) has been detected in more than 90% of Karposi sarcomas and could recently be demonstrated in RHE, we sought to detect HHV‐8 DNA in HH.


Tandem breakwater system consists of a conventional breakwater protected by a seaward submerged reef. The paper discusses physical model study on the hydraulic performance of an isolated as well as tandem breakwater system subjected to varying wave climate and water depths, while keeping a constant crest width of submerged reef The breakwater in both the cases are armoured with concrete cubes and the submerged reef is constructed with natural stones. It is found that the isolated breakwater is damaged for all waves except those of period 2.5 s. While a submerged reef of crest width (B) 0.40m placed at a seaward spacing(X) of 2.5m transmits only 52% to 81% of the incident wave height and thereby reduces the wave force on the main structure which inturn protects the inner main breakwater completely without causing any damage.


Inspired by recent theoretical proposal on the interesting piezomagnetism and C-paired valley polarization in V2Se2O monolayer, we predict a stable antiferromagnetic Janus monolayer V2SeTeO with altermagnetic configuration using density functional theory calculations. It exhibits a novel multi-piezo effect combining piezoelectric, piezovalley and piezomagnetism. Most interestingly, the valley polarization and the net magnetization under strain in V2SeTeO exceed these in V2Se2O, along with the additional large piezoelectric coefficient of e31 (0.322*10-10 C m-1). The multi-piezo effect makes antiferromagnetic Janus monolayer V2SeTeO a tantalizing material for potential applications in nanoelectronics, optoelectronics, spintronics and valleytronics.


By agreeing to recount his three meetings with Jacques Lacan, Jean-Pierre Petit does much more than supplement a paragraph that has remained in the shadows of one-hundred-year history of psychoanalysis in France. He teaches us that a topological object, the Boy's surface, held the attention of Lacan to such an extent that its logical implication is to recast Lacan's earlier topologies, which he never undertook during his lifetime. Existence of an unperceived singularity of the cross-cap, demonstration proving the existence of such a singularity, detailed description of the Boy's surface and the transformations produced by the application of a cut on such an object are the three points he exposed to Lacan and which he agreed to share with us accompanied by the topological writings he carefully wrote out by hand.


The article is devoted to the methods and ways of activation of primary school learners' cognitive activity during the English lessons.


Seizure activity is a known complication associated with multiple sclerosis; however, it may also result from side effects of the treatments for the disease. A 21‐year‐old man with Tourette's syndrome, pedophilia, Asperger's syndrome, and multiple sclerosis experienced seizures after receiving therapy with interferon (β‐1a. Adjustments in his drug regimen led to the discovery of pseudoparkinsonism and other extrapyramidal symptoms. This case report illustrates how pharmacodynamic properties of drugs can complicate the treatment of neurologic disorders. Clinicians must be aware of the delicate balance between the signs and symptoms of disease states and the effects of drugs.


OECD countries faced highly contrasted employment patterns over the last three decades. However, this cross-national heterogeneity is mainly concentrated on particular demographic groups. Actually, Figure 1 shows that the employment rate of prime-age men has been quite similar across countries since 1970.1 In contrast, the employment rates of younger people, prime-age women, and older people display significant cross-country variations. Moreover, Figure 1 shows that OECD countries also differ in the evolution pattern of the employment rates of demographic groups. All OECD countries have undergone the same steady rise in female employment rates and a slight decrease in prime-age male employment rates. But while the employment rates of younger and older individuals have remained quite stable in AngloSaxon and Scandinavian countries, they both have dramatically fallen in Continental and Mediterranean countries.


The stent delivery system comprises an inner member (24), and a collapsible balloon attached (42) in a contracted state on the inner member (24). Retractable stent (22) is mounted around a deflatable balloon. At least a first thermoplastic member or elastomeric material (40) is disposed between the deflated balloon and the stent, thereby increasing the holding force between the deflated balloon and the stent. .FIELD 5


Although small firms are particularly sensitive to interest rates and other shocks, empirical work on corporate risk management has focused instead on large public companies. This paper studies fixed-rate and adjustable-rate loans to see how small firms manage their exposure to interest rate risk. Credit-constrained firms are found to match significantly more often with fixed-rate loans, consistent with prior research that shows the supply of credit shrinks during periods of rising interest rates. Banks originate a higher share of adjustable-rate loans than other lenders, ameliorating maturity mismatch and exposure to the lending channel of monetary policy. Time-series patterns in the fixed-rate share are consistent with recent evidence on debt market timing.


There is a widespread belief that cancer is caused, at least in part, by aberrant mental processes. A corollary of this belief is that cancer may be cured by the application of the mind. These ideas are fostered in Australia by a popular book "You can conquer cancer" by lan Gawler, a veterinary surgeon who attributes, at least in part, the development and subsequent cure of his own cancer to such processes. Critical examination of these beliefs finds evidence in their support to be lacking. None the less, many patients with cancer in this country follow the book's advice, often on the basis that it "at least can do no harm". While some patients may be aided to come to terms with their disease and to lead more fulfilling lives by taking up meditation and the positive approach to living that is described in the book, it also contains recommendations about orthodox treatments, life-style and diet which, If adopted uncritically, could be quite detrimental. The potentially harmful effects of accepting such unproved ideas about cancer need to be known more widely. Furthermore, because his ideas are making such an impact on the dayto-day treatment of cancer in this country, Gawler owes it to the community to justify, with evidence, his claims that by meditation patients with cancer may be enabled to achieve a cure of their disease in a way that is unattainable with orthodox medical treatment alone. In many ways the achievements of medical science in treating advanced cancer are not well-enough known. They include the cure of the majority of children with acute leukaemia; the cure of 80% or more of patients with cancer of the testis (the most common cancer in young men) and of Hodgkin's disease; the cure of about half the cases of high-grade malignant lymphomas; and the achievement of prolonged remissions and possibly cures in 20-30% of adults with acute leukaemia. Patients with advanced malignancies of several other types, including prostatic, breast and ovarian cancers, small-cell carcinoma of the lung, the chronic leukaemias and multiple myeloma, all can achieve improvements in the quality of life as well as the prolongation of survival. In some cases, such as with the use of hormonal agents for breast and prostatic cancers, the treatment that is required to effect these results has little toxicity. As a consequence of these advances, any visitor to a haematology or oncology clinic in a large teaching hospital today would be able to see a number of patients for whom a diagnosis of advanced cancer was made in the 1970s. None the less, taken over all, science has made only a modest impact on the problem of cancer. Cancer remains the second most common cause of death in our community, and no effective specific treatment is available yet for a number of common malignancies such as cancer of the pancreas, non-small cell carcinoma of the lung and advanced adenocarcinoma of the bowel. Even where effective treatment can be offered, to many patients the potential side-effects of surgery, radiotherapy and chemotherapy are perceived as unacceptable relative to their possible benefits. Furthermore, doctors often are criticised for their inability to discuss bad news sympathetically and for their failure to impart hope. Therefore, it should be no surprise that some patients are inclined to seek solutions outside the medical profession. Currently, a widely held belief is that the solution lies in alterations to mental attitudes and a return to "natural" living. It is postulated that mental attitudes determine the body's immune status and that this, in turn, determines the risk of the development of cancer. Thus, the hypothesis runs, if mental attitudes may lead to cancer, changing those attitudes may cure cancer. Interest and belief in this approach among the general public in Australia is so strong that a popular book on the subject beguilingly entitled "You Can Conquer Cancer" by lan Gawler, a veterinary surgeon, has sold many thousands of copies and, in fewer than six years, already is into its seventh printing. It is the most readily available book on cancer to be found in bookshops and health food stores throughout the nation. In contrast, books which provide broadly based information about cancer in a popular form and in a manner which the medical profession could recommend confidently (for example, those by Glucksberg and Singer, Baum, Clyne, and Bryan and Lyall) generally are displayed much less prominently, if at all. The situation now has been reached in some parts of the country that almost every patient with a newly diagnosed cancer either buys the book or is given it by a well-meaning relative or friend. Furthermore, thousands of patients, as well as their friends and relatives, have joined support groups around the nation that actively promote the views that are expressed in the book. The medical profession has maintained a low profile on the matter hitherto but, in my opinion, the growing popularity of the book and of the practices that are mooted in it are such that silence no longer is appropriate. The Gawler phenomenon now is having a significant


The invention provides a method for preparing graphene through a large-scale aqueous phase. According to the method, graphite serves as a raw material. The method comprises the following steps: intercalating the graphite by adopting an intercalator, so that interlayer spacing between graphene sheet layers is enlarged, and the interaction force between the layers is weakened; and directly treating the intercalated graphite through ultrasonic waves, stripping and uniformly dispersing the graphite in an alkaline aqueous solution with the pH value of 10-14, wherein the content of graphene in the dispersion can be over 100mg/mL (about 10 weight percent of graphene), the content of single-layer graphene in the aqueous phase dispersion is more than 90 percent, the equivalent diameter of the graphene sheet layers can be over 1-10 microns, and a graphene film formed by filtering has a complete lattice structure and high electric conductivity. The prepared high-concentration aqueous phase graphene paste can be stored for a long time and is convenient to transport and use. The method is simple in process flow, high in production efficiency, low in energy consumption and low in cost, a commercially available low-cost reagent is adopted, the reagent is easy to recover, and the production process is environment-friendly and pollution-free.


Study on transport and characteristics of organic matters in river waters with different watershed conditions Alam Seiya Nagao D-2 Associate professor Division of Geoscience Faculty of Environmental Earth Science. Abstract: △C and δC were used to study transport behavior of particulate organic carbon in major rivers in Hokkaido at spring-summer season. Water samples for the Ishikari River were collected from April to September in 2004. The Tokachi, the Teshio, and the Kushiro River water samples were collected at snow-melting period in 2004.There are positive correlations in POC contents and carbon isotopic values except for the spring sample of the Ishikari. The spring POM sample is different sources and transportation. However, there is a positive correlation between POC content and △C values at snow-melting period for the four river POM samples. The four rivers show similar transportation of POM at high water discharge although the river systems have different watershed environment.


We have synthesized a new layered oxychalcogenide La2O2Bi3AgS6. From synchrotron X-ray diffraction and Rietveld refinement, the crystal structure of La2O2Bi3AgS6 was refined using a model of the P4/nmm space group with a = 4.0644(1) A and c = 19.412(1) A, which is similar to the related compound LaOBiPbS3, while the interlayer bonds (M2–S1 bonds) are apparently shorter in La2O2Bi3AgS6. The tunneling electron microscopy (TEM) image confirmed the lattice constant derived from Rietveld refinement (c ∼ 20 A). The electrical resistivity and Seebeck coefficient suggested that the electronic states of La2O2Bi3AgS6 are more metallic than those of LaOBiS2 and LaOBiPbS3. The insertion of a rock-salt-type chalcogenide into the van der Waals gap of BiS2-based layered compounds, such as LaOBiS2, will be a useful strategy for designing new layered functional materials in the layered chalcogenide family.


Since 1950, the attention of the Czechoslovak Archaeological Institute has been focused on the study of the Early Neolithic in Czechoslovakia, and since 1960 the investigation of Neolithic society in all its aspects has been one of the principal assignments of the Academy of Sciences in the field of social sciences. In the years 1950-1952 a survey of a Neolithic site of the Danubian I or Bandkeramik, and Late Lengyel cultures, at Postoloprq in NW Bohemia, was undertaken and its results are now in the press. This investigation has shown, however, that NW Bohemia belongs to a peripheral region and that thus any findings made there have a local validity only. Unless they are taken in conjunction with evidence from a less peripheral region, they present a very distorted picture. For this reason a suitable site was looked for in eastern Bohemia, where it could be assumed (on the basis of an analysis of earlier finds in local museums) that particularly suitable localities could be found in the region.

European Union combines territories of 27 member countries and also economical, trade and financial aspects. It has an essential role in global problems and its importance is increasing equal to adoption of collective decisions in sphere of foreign policy. EU converses with all the world key figures and also with those who have their own opinion about world and their own interests. During the last years the meaning of EU as an independent figure in the modern general European safety system is intensifying. It is important to point that diplomacy stays the basement for mutual foreign and safety policy in EU, so that it is supported by trade, help, safety and defense if it's necessary. This policy is directed firstly to solve the conflicts and reach the international understanding. The topicality of issue. The historical development of Europe witnesses that guaranteeing of safety has been a task of various international political blocks and organizations. Exacerbation of untraditional threats influenced the strengthening of institutional and functional role of international organization in sphere of guaranteeing of safety. Dynamics of international processes points the increasing meaning of regional safety systems in providing of stability in the world. Mutual dependence of regional and global organizations of collective safety and defense is intensifying (UN, NATO, OSCE and EU). The aim of the article is an analyzing of European safety and defense police (ESDP) as policy in process of further closer integration within EU and in the relationships with other international safety organizations. The object of survey is mutual safety and defense policy of EU in the context of new threats to the regional and global safety. The subject of survey – international political specifies of formation and evolution, institutional and practical and international law mechanisms of ESDP since the second half of XX cen. – the beginning of XXI cen. The conclusions In such way, in the last 20 years political and institutional changes in EU has created the premises for the new perception of «purely European» safety space. The development of European safety conception is characterized by complex approach, determination of qualitatively new threats and at the same time emphasizes the accepting of values which are mutual for European countries. 1. Earlier in the EU state security relied entirely on the political defensive mechanism of NATO and the political mechanism of OSCE and the UN, the security problems are recently becoming further relevance for European policy and become «internal priority» of the European Union. EU concern for maintaining their own security, the creation of an appropriate system and its organization was implemented in an effort to strengthen the Common Foreign and Security Policy (CFSP). However, since its launch CFSP was ineffective political-legal and institutional mechanisms. Therefore, in 1999 the European Union introduced a new, more successful initiative called the European Security and Defense Policy (ESDP). It should be noted that this area of soft security, ie the post-conflict settlement and assist in civil management, and is currently the most successful and best functioning part of ESDP. Scope military solution is still considered controversial by most Member States and has many obstacles to achieve efficient operation. 2. The EU strongly and gradually approaching the ability to influence to European and international security. Over the last decade, the EU was able to significantly develop its military component of ESDP as an important link. In particular, the creation and development of military forces allowed the EU to take over peacekeeping missions as in Europe and beyond. 3. Enhancing the EU efforts in the area of foreign and security policy was due to the failure of the EU itself resolve the conflict in the Balkans, the knowledge of its own military and technological backwardness, the understanding of the changes in the content and scope of threats and recognition of the need to build an appropriate response strategy. This led to a conceptual change in European security policy and the emergence of initiatives to create a European military instruments of influence on world politics (in the so-called «hard security»). 4. Over the last decade, the EU had 23 civilian missions and military operations on three continents. These include the following: peace of the after effects of Tsunami Aceh (Indonesia), the protection of refugees in Chad, the fight against piracy in Somalia and the Horn of Africa. This suggests that the EU's role as a player in the security becomes tangible. As of November 2010 the EU has both thirteen military and civilian missions in 4 regions of the world: the European continent (the Balkans, Moldova / Ukraine), the Middle East, Asia and Africa. Also completed 11 military and civilian operations in the Balkans, the Caucasus, Asia and Africa. While EU operations using inputs NATO. Thus, we can speak of complementary efforts and mutually beneficial cooperation between the EU and NATO. 5. In the EU a priority for further development of ESDP recognizes no quantitative growth indicators and qualitative implementation of capacity in this area, which in turn confronts the EU Member States following objectives: reaching consensus on all aspects of common security and defense policy, development and learning new methodologies crisis management, effective use of international cooperation, strengthening the defense industry and military technology. 6. Motivation to improve the state of national security, stabilization of the internal and external situation, reducing dependence and further out from the influence of a number of other reasons make our country more actively in the foreign and security policy. The overall process of the EU integration process involves appropriate in all areas and sectors, including security, so further participation in the CFSP has a positive attitude affect the positioning of Ukraine in the security dimension of European geopolitical space. Achieving this goal is possible only in case of joint ownership of all political parties, the government and the President to improve geo-political situation of our country both in Europe and internationally.

Summary form only given. In this paper, we demonstrate the experimental evolution of ultra-broad spectra generated by photonic crystal fibers (PCFs) of different lengths, and theoretically analyze the nonlinear process based on our derived nonlinear propagation equation beyond the slowly-varying-envelope approximation (SVEA). The calculated results of the complicated frequency-dependent phase are significantly useful for extremely flexible and accurate active-chirp compensation by a 4-f pulse shaper with a spatial phase modulator for monocycle-pulse generation.

This article reports on the intersection between the field of health and the field of architecture and sees in this intersection the possibility of applying the Law on Technical Assistance. This study emerges as a result of the encounter between a Community Health Agent and an Architect in a slum in the North of Rio de Janeiro. With mediation as a defining aspect of their profession, the Community Health Agent builds knowledge of the territory during home visits, which also provide the basis for building relationships of trust, extrapolating his role as representative of an institution. The richness of his performance comes from his dual condition as a resident and agent. This specific condition, which we only find in the field of health, brings possibilities for expanded action especially when thinking about intersectoral policies that involve, among others, technical assistance in architecture and engineering according to law 11.888/2008, giving rise to new ways of acting on the territory to overcome known limitations of urbanization projects and regularization of precarious settlements.

We here report on a protocol of system performance for the microwave radar breast health monitoring prototype. The device aims to detect breast cancer at an early stage and operates in the multistatic mode with 16 transceiving antennas. After introducing hardware changes, we developed a system performance protocol to repeatably test our system in preparation for clinical trials. It includes repeated scans using breast phantoms, and we investigated if the phantoms can be used without a matching medium not only with an ideally-fitting antenna housing, but also with the prosthetic bra used in clinical trials. We compare the system performance with both antenna housing options and introduce a system performance protocol for the clinical trials.

It is determined that age conditions differ according to the following signs: the number of vegetative branches on the reproductive suckers, the degree of the development of the composite pleiohasial inflorescence, the degree of the development of the underground part of the plant.


eScholarship provides open access, scholarly publishing services to the University of California and delivers a dynamic research platform to scholars worldwide. Abstract: Using data from a field experiment in Kenya, we document that providing individuals with simple informal savings technologies can substantially increase investment in preventative health and reduce vulnerability to health shocks. Simply providing a safe place to keep money was sufficient to increase health savings, through a mental accounting effect. Adding an earmarking feature was only helpful when funds were put towards emergencies; earmarking for preventative health reduced savings on average, because the liquidity cost of tying up money was too great. Providing social pressure and credit through a ROSCA-based savings scheme had very large effects. Abstract Using data from a field experiment in Kenya, we document that providing individuals with simple informal savings technologies can substantially increase investment in preventative health and reduce vulnerability to health shocks. Simply providing a safe place to keep money was sufficient to increase health savings by 66%. Adding an earmarking feature was only helpful when funds were put towards emergencies, or for individuals that are frequently taxed by friends and relatives. Group-based savings and credit schemes had very large effects. numerous administrative Sefira IRB no relevant or material financial relate to the research this paper. All

According to Chronicle of Su Shi,in 1085,when Su Shi passed Yangzhou to Dengzhou,he was invited by Yang Kanggong to write a poem for his Drunk Taoist Stone;however,the poem was written down in September of the next year when Su Shi was in Huaikou,and the stone was still stored up by Yang Kanggong in Yangzhou.Therefore,the poem on the stone itself was not written by Su Shi,but by an officious man.


We introduce a new family of connectivity-based garbage collectors (Cbgc) that are based on potential object-connectivity properties. The key feature of these collectors is that the placement of objects into partitions is determined by performing one of several forms of connectivity analyses on the program. This enables partial garbage collections, as in generational collectors, but without the need for any write barrier.The contributions of this paper are 1) a novel family of garbage collection algorithms based on object connectivity; 2) a detailed description of an instance of this family; and 3) an empirical evaluation of Cbgc using simulations. Simulations help explore a broad range of possibilities for Cbgc, ranging from simplistic ones that determine connectivity based on type information to oracular ones that use run-time information to determine connectivity. Our experiments with the oracular Cbgc configurations give an indication of the potential for Cbgc and also identify weaknesses in the realistic configurations. We found that even the simplistic implementations beat state-of-the-art generational collectors with respect to some metrics (pause times and memory footprint).


Conflict detection is one of the fundamental elements in air traffic control. The output of conflict detection is the important input for conflict resolution which is an important task in maintaining safety and efficiency for flights. Even though there are tools to support air traffic controller in detect potential conflict, their quality and accuracy are still limited since the difficulty in encapsulating uncertainty in predicting flight trajectory. To tackle that challenge, several studies focus on applying probabilistic approaches by modelling aircraft dynamic and uncertainty. Those approaches share common limitations such as their assumption about uncertainty distribution and high computational cost for locating and computing the probability of conflict. In this work, we propose a data-driven approach to model the uncertainty of flight trajectory combining with technique for quickly locating position with highest conflict probability. Firstly, we use generative models to capture the complex trajectory pattern and its uncertainty directly from ADS-B data. Those model are used to predict aircraft position in future with uncertainty given current aircraft information. To compute the time at which two aircraft have highest probability of conflict, Monte Carlo method will be applied. Since conflict is a rare event so that the cost will be expensive, Bayesian Optimization algorithm is applied to quickly identify that time. Final the performance and computational cost of our approach is compared with Monte Carlo method using simulated data.


The elastoplastic deformation which occurs during sliding leads to wear. The mechanical wear rates of metals can be related to the plastic strains induced in their surfaces as they rub together [1]. Different metals respond in different ways to the applied stress, and there may be different mechanisms of surface fracture when tribological conditions change [2]. In the situation where one of the sliding surfaces is harder than the other, the strains induced in the worn surface through asperity interaction were calculated. A quantitative law of wear rates has been established through the extent and rate of change of the strains. Finite element analysis was also used for the prediction of the strains. Experimental tests were performed on soft metals to verify the calculations. The influence of the plastic deformation of the soft surface on the formation of wear particles was studied using a wedge test, specially developed for the purpose. A hard wedge slides against a softer material. The simple geometry allows the strain cycle induced by a passage of the wedge to be calculated [1,3]. For most of the metals studied, wear particles form by fracture after defect generation through fatigue, the wear rate depends on the number and magnitude of the strain cycles [3]. This was confirmed by examination of the worn surface. However, with copper, the most ductile of the materials studied [3], it was impossible to find any cracks in the worn surface, which indicated that wear particles were being produced by some other mechanism. Further evidence of this came from a comparison of the friction traces from different materials. For most metals, the friction trace was smooth; but for copper, the smooth trace became rough and irregular from time to time. In this paper, we propose a model to explain the anomalous behaviour of copper, based on the evolution of its surface microstructure during the tests. A micorstructurally induced plastic instability is to be expected beneath the surface after sufficient strain, which will lead to the sudden detachment of wear particles, and an irregular friction trace whilst this occurs.


The design of secure network-based systems is a very important aspect of the software development processes. For process design and composition, the emerging model-driven software development approach discloses new challenges. Existing approaches often only focus on their specific view—i.e. business process modeling, security modeling, code generation—neglecting interoperability with and reusability of


Using as a case study Christopher Nolan's blockbuster film The Dark Knight, and building from recent work on disability and humor, the article explores the disabled body as a potential site of camp performance and outrageous parody. The Joker's sartorial flair and his commitment to style over substance, it is argued, construct him as a variation of the Wildean homosexual dandy whose superficiality is politicized as a form of queer resistance to both capitalism and the institutionalized hierarchies of the state. Furthermore, the crip dimensions of the Joker's drag performances – and in particular, the narrative agency with which he continually destabilizes the origins of his facial scar – extends that camp sensibility beyond sexuality to explore disability as performative process rather than a pathological state. Developing a concept of disability camp not only helps us to shake up the representational terrain of both queer studies and disability studies, but also provides new and exciting opportunities for theorizing the intersections of disability, humor, and performance.

The purpose of this study is to apply the concept of organizational ambidexterity as a conceptual lens to increase the understanding of tensions between exploitation (continuity) and exploration (change) in Agile software development (ASD) project teams, and particularly the balancing (ambidextrous) strategies utilized.,A conceptual framework was constructed from interdisciplinary sources on ambidexterity. A literature review of publications on ambidexterity in ASD was then performed, and the results from the selected publications were classified according to an extension of the conceptual framework.,Contextual ambidexterity in ASD is affected by the four basic coherent concepts: time, task, team and transition. The study found that most ambidextrous factors and strategies were task and team-related. In addition, a mixture of hard (performance) strategies and soft (social) strategies is needed in order for people/teams to (be able to) become ambidextrous.,To provide a better understanding of ASD, it is important to identify a broader set of ambidextrous factors and strategies that can impact ASD project teams. The expanded conceptual framework can serve as a basis for future empirical research and provide insights to practitioners on how to strengthen ambidexterity in ASD projects.,The contribution is of great importance for ASD research and practice, as ASD methods are a popular method for managing projects within ASD and in other nonsoftware organizations. In addition, as more and more organizations struggle to deal with rapidly changing environments, interest in the phenomena of paradoxical tensions and the strategy (ambidexterity) to deal with these tensions increase.


Implementation of advanced antenna concepts is essential for the success of 5G and beyond. Conventional beamforming networks like Butler matrices, Blass matrices, Rotman lens networks, and conventional adaptive arrays are very favorable. Meanwhile, use of multi-element antennas associated with the implementation of advanced algorithms are the backbone of efficacy of spatial processing. Beamforming of phased arrays and MIMOs could be utilized to develop antennas that operate in urban or suburban areas. Meanwhile, high gain and super directive repeaters have been designed to extend coverage to rural areas as well. In this presentation, we will provide a brief review of candidates for 5G antennas and radiating systems, and present examples of some commercially available antennas.

SUMMARY Ground roll attenuation of land seismic data is still an outstand-ing and challenging problem. Deep learning is a powerful tool for separating signal from noise. Recently, supervised deep-learning-based methods have been applied to ground roll attenuation. However, they require a large set of correspond-ing clean seismic datasets as labels. Constructing realistic training samples for network training is an unsolved problem. To circumvent it, we proposed an unsupervised deep learning method for attenuating ground roll where no training labels are utilized. The generator network first learns self-similar features before any learning. Therefore, if the reflections are self-similar in the time-space domain, but the ground roll is not, the network can extract the reflections before the ground roll. To make reflections look more self-similar than the ground roll, we apply the normal moveout (NMO) correction to flatten the reflections. Access to NMO correction makes the method also model-driven. The combinations of data-driven deep learning and a model-driven procedure are critical to the success of the proposed method. We use both synthetic and field shot data to illustrate the fidelity and validity of the proposed methods. The field data example shows that our proposed method can attenuate strong scattered ground roll.


Pollution source estimation is an active research area nowadays. Researchers are trying to estimate the pollution source based on a set of data from monitoring sites. This kind of problems is known to be ill-posted and sensitive to computational errors. In this paper, we present a method using a space-time radial basis function to estimate the pollution source. To overcome the problem of ill-conditioning, we first use the data from the monitoring site to get a continuous approximation of the data. Then, we use this data together with the governing equation, and boundary conditions to set up an over-determined system of equations. The single value decomposition is used to get the least square solution. An example is used to illustrate the method. It is found that our method is effective and accurate in estimating the pollution source.


A new immunohistochemical method for analyzing the localization of gibberellins was developed and applied to rice anthers. This method uses 1,3-diisopropylcarbodiimide gas fixation to prevent the drift of gibberellins during the fixation procedure. Spikelets before anthesis were frozen in liquid nitrogen and lyophilized. They were then fixed with diisopropylcarbodiimide gas in a desiccator, which catalyzed amide formation between the 7-carboxyl groups of gibberellins and the amino groups of proteins in the tissue. The fixed spikelets were embedded in paraffin and sectioned, the sections being stained with the anti-GA1-Me antibody and visualized by using an immunoperoxidase system. The anthers just before anthesis were stained well, while those 4–5 days before heading were not stained. We analyzed the gibberellins in an extract of the rice anthers by an immunoassay, using the anti-GA1-Me antibody. On the basis of the results, we conclude that the major substances stained in this immunohistochemical study s...


In this paper, we examine the "geography of mobility" for rural India. We study the spatial determinants of intergenerational occupational mobility across villages in India. Using a nationally representative data-set – the Indian Human Development Survey of 20112012, which has detailed information on the occupations of fathers and sons as well as data on village level covariates, we find clear effects of village level factors in explaining intergenerational occupational mobility, with remoteness of the village, its agro-ecological and climactic conditions, infrastructural public goods, and its economic prosperity being important predictors of whether the son is less likely to follow his parent's occupation in the village. Preliminary. Please do not cite.


This House of Lords judgment dealt with three separate appeals, heard together on the same day (17 October 2007). Previously, in the Court of Appeal, the cases had been joined in the same way. The three appellants had each been tried on indictment, but in different courts and on unrelated charges. In each of the first two cases (R v Abdroikof and R v Green), the trial jury had as one of its members a serving police officer. In the third case, a solicitor employed by the Crown Prosecution Service was one of the jurors. The three conjoined appeals raised the same question: whether a fairminded and informed observer would conclude, on the facts of each case, that there was a real possibility that the trial jury was biased. The Court of Appeal had answered this question in the negative ([2005] 1 WLR 3538). The appellants now sought the opinion of the House of Lords. Baroness Hale was quick to point out that 'like many simple questions, it is by no means easy to answer' ([2007] UKHL 37 at [45]). At trial in the Central Criminal Court, the first appellant, Nurlon Abroikof, had pleaded guilty to two counts of theft and defended unsuccessfully a charge of attempted murder. There was a minor issue concerning one aspect of the evidence of a police witness. When the jury retired to consider their verdict, the foreman of the jury sent a note to the judge, revealing that he was a serving police officer and expressing some concern; namely, that he could be called up for police duty at the Notting Hill Carnival on the following Bank Holiday Monday, when the court was not sitting, and that he might there meet one or more of the police officers who had been called to give evidence at the trial. With the acquiescence of defending counsel, this juror was directed not to report for police duty on the Monday. The second appellant, Richard Green, had been stopped and searched by police officers. During the course of the search, a police officer, Sergeant Burgess, placed his hand into the appellant's pocket and pricked his finger on a used syringe. Green was charged with the offences of assault occasioning actual bodily harm and having a bladed or pointed article. He pleaded not guilty to both charges. There was a dispute on the evidence between him and the police sergeant concerning the manner in which he was searched, and what he and the sergeant respectively said. He was convicted by a jury sitting at Woolwich Crown Court. Some time after the trial, by chance, the appellant's solicitor discovered that a police officer, PC Mason, had been a member of that


The aesthetic zone presents a dilemma for prosthetic rehabilitation. Prosthetic restoration of significant alveolar bone loss in the aesthetic zone is often challenging. The Andrews Bridge fixed removable system can be used in such cases as it combines the benefits of a Fixed Partial Denture (FPD) with the aesthetics of a Removable Partial Denture (RPD) to restore lost teeth and gingiva while addressing the aesthetic challenge of significant alveolar bone loss. It reduces the denture bulk and provides good retention and patient comfort. There is no need for palatal or lingual flange covering, as in a regular RPD.

physalaemin. However, at these higher concentrations physalaemin caused marked contraction of the muscle by itself which masked the normal responses toelectrical stimulation and drugs. At 1.25 ng ml-1 (1: 0.9 M) of physalaemin, reversible increases were still observed for contractions to acetylcholine (14.6 %) and nicotine (47.5 %) but not to 5-HT. Contractions to histamine were not potentiated by physalaemin at any of the concentrations tested (Fig. 1). These observations show that physalaemin behaves like substance P and sensitizes ileal smooth muscle to cholinomimetics. The small increase in the size of the contractions produced by 5-HT was at variance with the depression of contractions of that agonist described by Beleslin & VaragiC (1960) with crude substance p. Thus whether the mechanism of this sensitization observed with physalaemin is similar to that described for substance P remains to be determined. This work was supported by a grant of the Belgian 'Fonds national de la recherche scientifique'. We wish to thank Farmitalia S.p.a. Laboratories for generous supplies of physalaemin and Mrs C. Debruyne for her technical assistance.


The oxidative dissolution of sulfide minerals produces acid mine drainage (AMD) with release of high concentrations of toxic elements such as Fe, As, Pb, Cu, Zn and sulfate s . Resulting waters, with high concentrations of dissolved solids, can infiltra te to the aquifers or can be incorporated into rivers, causing consi derable damage to the environment. The most common sulfide mineral is pyrite (FeS2) ' The dissolution of FeS2 has been widely studied using several experimental methodologies (e . g . , batch and flow through experiments, ex situ AFM, etc.) that contributed to the existing knowledge of the pyrite disintegration. In this study we try to elucidate on the surface mechanism(s) that control the pyrite dissolution by means of vertical scanning interferometry (VSI) in acidic conditions and oxygen saturated atmosphere. Using this technique it is possible to quantitatively map changes in mineral surface topography at the sub-nanometer-scale vertical and micro meter-s cale lateral resolutions (Luttge et al. 1999; 2003; Arvidson et al. 2003).


The effects of various carriers on the reduction of the glass transition temperature (Tg) and the dyeing transition temperature (Td) of an acrylic fibre in a cationic dyeing system have been investigated. Linear relationships were found between the concentration of carriers in the fibre and the reduction of the Tg and the Td of the fibre. The efficiency of various carriers in reducing the Tg and the Td, when compared in terms of the molar concentrations of the carriers in the fibre, was found to be similar, regardless of the carriers used.

In view of the fact that randomness and fuzziness often exist simultaneously,this paper proposes a fuzzy random rough set model based on inclusion degree in the fuzzy random approximate space. Firstly,the concept of fuzzy random approximate space is introduced. Secondly,by using the inclusion degree,a new rough approximation operator on the basis of fuzzy random set is proposed in the fuzzy random approximate space. Finally,some properties of this approximate operator are discussed.

ABSTRACT The objective of this study was to investigate the effect of different microwave drying techniques on the drying kinetics and product quality of dried green soybean. Experiments were conducted using microwave vacuum drying (MVD), pulse-spouted vacuum microwave drying (PSMVD), pulse-spouted microwave drying (PSMD), and microwave freeze drying (MFD). Parameters of apparent density, color, processing temperature, expansion ratio, rehydration ratio, texture, and microstructure of the dried products were determined. The results showed that the MFD green soybean had a small change on bright color, compared with the fresh samples, but the drying time was the longest among the four methods. The bright color value of PSMVD/PSMD/MVD, respectively, was 79.77, 71.43, and 55.45, and drying time of them was slightly different. The PSMVD/PSMD showed advantages over MVD by improving the product quality.


Switchable optical elements incorporating polymer structure and a liquid crystal material offer devices with a voltage controlled phase difference at low cost. The polymer structure may be fabricated using established replication techniques. Earlier work has demonstrated such devices with good optical quality and high diffraction efficiencies. Such a material allows the director to be actively driven either towards homeotropic or planar alignment depending upon the frequency of the drive waveform. For this investigation devices were fabricated using a dual frequency liquid crystal with a polymer structure. Use of a liquid crystal material with a dielectric anisotropy inversion has the advantage in this case that the liquid crystal orientation is less dependent upon surface forces for switching effects. Liquid crystal reorientation and therefore optical switching is field driven into different orientations. Measurement s of the intensity of the transmitted diffraction orders as a function of time were carried out as means to compare the liquid crystal reorientation times for devices with different gratings. The same devices were driven in two ways; changing driving frequency so switching was always field driven or by changing applied voltage so that switching was partly determined by surface forces. It would be expected to observe faster optical switching due to an applied field; this was not always observed to be the case, this may be due to differences in the initial state between field dominated and surface force dominated initial conditions. Work to understand this more fully is in progress.

Manifesto was written by Marx in January 1848 in Brussels.It was deeply influenced by Principles of Communism,which was written by Engels.At the same time,Manifesto's language and structure were very close to Engels's works.But Manifestowas really written by Marx himself.Nowadays,many people want to know the answer of "who is the real author of Manifesto",because there are three views about this topic.By studying the Manifesto and Principles of Communism,we can find that the most fundamental difference between them is the "core theory"—historical materialism.Accordingly,the founder of historical materialism is the real author of Manifesto.However,Germany Ideology,the first public discussion of historical materialism,also was broadly discussed by people.The original manuscript of "Feuerbach Chapter" showed that the main author of Germany Ideology was Engels: Engels wrote text,and Marx wrote additional comments.However,the depth of thought,philosophical logic,characteristics of language of Germany Ideology made this work be regarded as Marx's work.Therefore,the creator of historical materialism also be discussed and studied by the researchers.

This paper analyzes the methods of rating attribution of the major international agencies (Moody's, Fitch and Standard & Poor's) between 2005 and 2010 for a sample of Italian and European listed banks and tests empirically, through the multivariate analysis of Ols, the possible relations of dependence between ratings and principal indicators of the banks and macroeconomic and market variables.The empirical analysis seems to support the view that rating agencies take into account the dynamics of financial variables, macroeconomic and confidence indicators considered in this research


The Diabetes Control and Complications Trial (DCCT) convincingly demonstrated that intensive insulin therapy reduces the microvascular complications associated with diabetes, including retinopathy, neuropathy, and nephropathy. 1,2 However, intensive insulin therapy that lowers blood glucose towards normal levels also significantly increases the risk for hypoglycemia. Moderate hypoglycemia can acutely affect cognitive ability, leading to temporary stupor and confusion. Severe hypoglycemia can lead to seizures, coma, and even death. Therefore, hypoglycemia causes recurrent morbidity that can interfere with the ability of individuals to work, as well as to perform activities of daily living. 3 The fear of a

In this paper, we give complex symplectic geometry characterizations for symmetric extensions (including self-adjoint extensions) and Priedrichs extension of the minimal operator generated by nth-order symmetric differential expression, defined in the weighted Hilbert space L2(I,r(x)) (the non-degenerate interval I, with endpoints -∞≤a,b≤∞). The necessary and sufficient conditions which ensure that its extensions are symmetric extensions, Priedrichs extension are obtained respectively.


The concept of Literature is associated with the emergence of national consciousness around 1800; its master genre is the novel. But in the developing consumer society of the nineteenth century, the novelist's fiction of authentic life becomes asymptotic to his own, culminating with Proust, whose novel is a series of intermittent narratives structured only by the ultimate realization of the narrator's literary vocation. This desultory structure is homologous to that of the blog, the auto-narrative of today's archival society. But although the ultimate narrative artwork is a series of semi-connected tales, we still need traditional novels and stories that give meaning to the life of desire.


"Steady Yin and vexed Yang" was firstly described in Major Discussion on the Theory of Yin and Yang and the Corresponding Relationships Among All the Things in Nature of Plain Conversation. Under the guidance of this theory,in syndrome differentiation,the waxing and waning of Yin and Yang of the patients can be judged by their movement and quiescence. In clinical medication,the medicine can be regulated to keep balance of Yin and Yang. There are some chief prescribing examples and medical cases of PU Jiazuo following the theory of "steady Yin and vexed Yang",which may be helpful to analyze its clinical application.


Gurinder Chadha and Mira Nair's films define diaspora as a diaspora space where women are portrayed as change agents. This paper explores how Chadha and Nair provide a different representation and possibilities for South Asian women in the diaspora in the description of arranged marriages and interracial love relationships so that they present pioneering female characters that subvert orientalist misconceptions about the South Asian Subcontinent and South Asian women. By so doing, this essay confirms how Chadha and Nair's selected films propose new postcolonial models that promote the construction of new roles for female characters in cinema that challenge the racial and gender inequality suffered by women in the United Kingdom, the United States of America and the South Asian Subcontinent.


285 Background: The Oncology Care Unit (OCU) is an urgent care center open during after-hours and weekends for patients with cancer and blood disorders at the Mount Sinai Hospital. This 6-bed, nurse practitioner-run unit aims to decrease the need for emergency room (ER) visits and hospitalization in this high risk patient population. Herein we characterize utilization of this unit for urgent clinical management ("sick visits"). Methods: We identified all patients treated in the OCU between 5/12/17 and 4/8/18, and collected information on diagnosis, treatment, and utilization of the ER or hospitalization. We used descriptive statistics to identify characteristics of those patients treated in the OCU. Results: Of the 1,934 visits to the OCU, 100 (5%) were coded as "sick visits". Of this cohort, 39% had solid tumors, 44% liquid tumors, and 17% benign hematologic conditions. Among the oncology patients, the average number of prior treatment lines was 4.6 and average time since diagnosis was 51.3 months. Of all cancers, 84% were classified as advanced stage or high-risk. Treatments for the entire group included: transfusion (T, 20%), hydration (H, 20%), and infusion (I, 13%). Similarly, 39% of visits were for H+I, 3% for T+H, 4% for T+I, and 1% for T+H+I. 5% of patients had a repeat, unplanned OCU sick visit in the next 7 days. Among the sick visits, 28% resulted in hospitalization, with a 14-day average length of stay. Further results are shown in Table 1. Conclusions: The OCU provides enhanced diagnostic and therapeutic services for high-risk hematology/oncology patients. These services often exceed the capabilities of a busy practice and would otherwise prompt an ER visit and/or hospitalization. We now aim to study the effect of the OCU on ER utilization and admission rates as well as to analyze its cost effectiveness. [Table: see text]

Over more than 85,000 chemicals registered for commercial purpose all over the world, only one-tenth have been tested for potential health effects. These chemicals are very hazardous above the threshold value and potentially harmful for human health and environment. The number of chemicals or toxicants are the integral components in production of important materials and goods and a few may adversely affect human reproductive health. Reproductive health involves all of the reproductive processes functions and systems at all stages of human life. Due to environmental contaminants during pregnancy, the risk of pregnant women susceptibility to poor outcomes increases. Exposure of toxicants and further assessment including the study of their distribution and determinants of substances or factors effecting human health is an important issue in occupational epidemiology. Reproductive toxicity caused deleterious response in post pubescent male and female and in primary infertility and sterility. Contaminants and toxicants, or their related metabolic products transport to the target organs, like thyroid, ovaries, testes etc. They exert their bio-chemical effects. Some contaminants and toxicants can be stored for prolonged periods of time in bones, muscles, adipose tissues, and other cellular tissues. These contaminants can reside in the body for prolonged time based on their half-lives. This can further continue to leach from these cellular tissues and, are transported to target site of organs leading to the change in their genetic functions and expressions. Exposures to some biological and chemical contaminants cause serious illness on reproductive and genetic disorder. Quantifying risk with traditional experimentations is challenging because of its limitations to find out precise effect for daily exposure. Due to this reason, it is difficult to create clear clinical guidance that addresses the potential health effects of lower levels of exposures, which are more common in the population


Abstract. Tarraf SA, Talaat IM, El-Sayed AEB, Balbaa LK. 2015. Influence of foliar application of algae extract and amino acids mixture on fenugreek plants in sandy and clay soils. Nusantara Bioscience 7: 33-37. Two pot experiments were conducted to study the effect of foliar application of algae extract and amino acids mixture on the growth and chemical constituents of fenugreek plants (Trigonella foenum-graecum L.). Plants were sprayed with different concentrations of algae extract (0.0, 2.5, 5.0 g/L) or equivalent of amino acids mixture (0.0, 0.625, 1.25 g/L). The results indicated that foliar application of amino acids mixture enhanced the vegetative growth of fenugreek plants, especially when plants were sprayed with 1.25 g/L amino acids mixture. Data also show that total nitrogen, essential oil percentage, and yield followed the same trend. These results hold true for plants cultivated in either clay soil or sandy soil. Data also indicated that foliar application of algae extract to fenugreek plants significantly increased plant height, number of leaves, number of branches and fresh and dry weights of plant at vegetative growth stage and flowering stage of fenugreek plant, especially in plants treated with 5 g/L algae extract in sandy and clay soils, respectively. Treatment of fenugreek plants with algae extract markedly increased nitrogen, phosphorous and potassium contents, especially at 5 g/L.

Objective To evaluate the significance of cerebral state index(CSI)used in patients undergoing general anesthesia.Methods Forty patients,ASA class Ⅰ or Ⅱ,were randomly allocated into two groups with 20 cases each.Anesthetic depth was judged and anesthetics was administred by CSI monitoring(being kept in 50±5)in group A or based on the experience of anesthetist.Anesthesia was induced and maintained with midazolam,fentanyl,propofol and vecuronium.SBP,DBP,HR,ECG,SpO2 and CSI were monitored.Awake time and anesthetic consumption were recorded.The OAA/S was graded during induction and correlative coefficient between OAA/S and CSI was calculated.Results The changes of SBP,DBP,HR and CSI were less in group A than those in group B(P0.05).Awake time was shorter in group A than that in group B and restlessness drowsiness,nausea and vomitting after extubation were less in group A than those in group B.No awareness case during operation was seen in group A,but one case suffered from awareness in group B.The rank correlation between CSI and OAA/S was significant.Conclusion CSI monitoring can dynamicly reflect cerebral physilological functions during general anesthesia and is helpful in judging anesthesia depth and directing the administration of anesthetics.


This paper firstly generalizes a kind of new operator, i.e. convex-power condensing operator, which was obtained by Sun Jingxian in paper [1], and defines a new class of operator, i.e. − P convex-power condensing operator in locally convex space. Also, a new fixed point theorem of this new operator is proved. Finally we apply the results obtained to investigate the existence of solutions for nonlinear Volterra type integral equations in locally convex spaces.


AT the time of the discussion in the Spanish Council of State concerning the decision of the Ecuadorian-Peruvian Boundary dispute, upon which His Majesty the King of Spain had been asked to arbitrate, the President of the Council is said to have remarked, " Beyond the natural boundaries, raised by the hand of God, it will be difficult for Ecuador to hold territory, for she is the Switzerland of the Americas.,, This remark is indeed true, for a striking similarity exists between the Alpine Republic and this country in the Andes?both having as common features lofty snow-clad peaks, deep ravines, and broad valleys enclosed by great mountain ranges?and the comparison enables one to form a topographical idea of Ecuador. The Republic of Ecuador, which with the exception of Uruguay is the smallest of all the South American Republics, lies between 20 N. and 6? S. lat. The longitudinal extension of the Republic is as yet undecided, for, although many years of discussion have passed and many decision s have been made, the Eastern and Southern frontier limits are still in dispute with the neighbouring Republic of Peru, and some territory is in litigation with Colombia. One is almost safe in claiming that Ecuador has more boundaries than any other country, for there are maps of the Republic showing six different frontiers according to six different opinions. There are the limits claimed by the Government of the Republic, which take in the greatest extent of territory and stretch far to the east, including a vast portion of the " Oriente," that territory lying to the east in the great Amazonian plain. This delineation of the frontier was made by Restrepo and Humboldt in the eighteenth century. Another frontier line is that known as the Pedemonte Mosquera line, and was drawn in 1830. The third is the provisional boundary made according to Menendez-Pidal, the Spanish High Com? missioner, in 1887. The fourth is the line drawn according to the ideas set forth in the Garcia Herrera agreement. The fifth is the boundary as outlined in 1909 by the Spanish Council of State. The sixth is that claimed by the Government of Peru. These limits of Ecuador are

The science of microsurgery is briefly reviewed in an historical context. Microsurgery is less than 100 years old. Its first use was in ophthalamic surgery around 1887 using a monocular microscope. In later years the monocular scope was replaced by the Zeiss binocular microscope. Microsurgery in gynecology however dates back only about a decade. In 1967 the first published report of microsurgery for gynecology was published. It was not until 1977 that an international symposium was held concerning the use of microscopic techniques in fallopian tube repair. Historical moments associated with the more extensive use of microsurgery found today are briefly mentioned and include introductions of new equipment and technique refinements. Today microsurgery finds limited use in salpingolysis salpingostomy and tubal implantation. Its most useful role is in improving reanastomosis results. It is emphasized that microsurgery is not a new set of techniques but rather an adaptation of older surgical techniques which requires greater discipline in the operating room and extreme gentleness and accurate tissue handling.

Summary 4-Ethylguaiacol is a phenolic model compound used to study the oxidation of lignin. A new method was developed to determine 4,4′-diethyl-6,6′-biguaiacol, an unwanted side-product, in the oxidation of 4-ethylguaiacol. The sample is extracted with ethyl acetate to separate 4,4′-diethyl-6,6′-biguaiacol from the water-soluble oxidation catalyst. No other treatment is required before analysis with a standard UV-Vis spectrophotometer. The spectrophotometer is calibrated to measure concentrations of 4,4′-diethyl-6,6′-biguaiacol up to 0.3 mM. With the new method, the concentrations of 4,4′-diethyl-6,6′-biguaiacol can be reliably determined over a wide alkaline pH range. The performance of the method was demonstrated in experiments investigating the formation of 4,4′-diethyl-6,6′-biguaiacol in the autoxidation and cobalt-sulphosalen catalysed oxidation of 4-ethylguaiacol. In the conditions of the studies (1 bar oxygen pressure and 50°C), a low (0.01 mM) concentration of Co-sulphosalen clearly increased the total conversion of 4-ethylguaiacol. However, relative to autoxidation, the conversions achieved in the presence of the catalyst were just as sensitive to pH, and the yields of the undesired dimeric product, 4,4′-diethyl-6,6′-biguaiacol, were higher.


The utility model discloses a water cup for blind people, which comprises a cup body, wherein an alarming device is arranged on the cup body; the alarming device comprises a power supply, a sounder and a water level switch connected by water in the cup body; and the power supply, the sounder and the water level switch are connected in series. In the water cup for the blind people, the water level switch is connected when water in the cup body receiving water rises to a certain height, and the sounder gives a sound to remind the blind people of the fact that the water cup is to be fully filled and of stopping receiving water to protect the blind people from being burnt by overflowing hot water; the blind people can turn on a circuit by using a remote controller to allow the sounder to give a sound, so as to find the water cup quickly; and a manual switch in the alarming device can turn off a circuit, so that the sounder can stop giving sound in a cooling process of the hot water. The water cup for the blind people can save electrical energy and is convenient for use.


This work proposes a geometric feature-based descriptor for efficient Facial Expression Recognition (FER) that can be used for better human-computer interaction. Although lots of research has been focused on descriptor-based FER still different problems have to be solved regarding noise, recognition rate, time and error rates. The Japanese Female Facial Expression (JAFFE) data sets help to make FER more reliable and efficient as pixels are distributed uniformly. The proposed system introduces novel geometric features to extract important features from the images and layered Hidden Markov Model (HMM) as a classifier. The layered HMM is used to recognised seven facial expressions i.e., anger, disgust, fear, joy, sadness, surprise and neutral. The proposed framework is compared with existing systems where the proposed framework proves its superiority with the recognition rate of 84.7% with the others 85%. Our proposed framework is also tested in terms of recognition rates, processing time and error rates and found its best accuracy with the other existing systems.


The discharge parameter, also known as the volumetric flow rate of a fluid, is defined as the water volume passing over the cross-section per unit time. The discharge is one of the most important but also the most demanding parameters within the fields of hydrology and hydraulics. There are many different systems available for measuring these variables, however most of them are intrusive (i.e. must be located within the stream). There are some other systems that are non-intrusive, but they are constrained in their relative orientation with respect to the water surface (e.g. radar systems). Image processing methods are a revolutionary measuring technique and possess certain clear advantages since there is no need for expensive installations. Furthermore, they offer more flexibility than other non-intrusive measurements systems. SEBA Hydrometrie GmbH & Co. KG and Photrack AG have developed a new camera-based gauge for both water level and flow velocity detection, which is called "DischargeKeeper". The DischargeKeeper is a completely new method for the continuous acquisition and storage of flow velocity profile, water level and flow rate of natural water streams, irrigation and waste water channels. The DischargeKeeper consists of an IPcamera, an infrared beamer, and a processing unit with remote data transmission. The surface velocity profile is measured by means of an optical method for capturing the flow velocity. The water level detection is carried out simultaneously by an image processing technique. Subsequently, the discharge is calculated directly on site. The equipment was tested at several sites and under different weather and light conditions. The validation of the DischargeKeeper was carried out by comparing the flow determined by the newly developed gauge, against the flow measured by a reference gauge. The correlation between the measurements carried out by the camera-based system and by the reference gauge was highly satisfactory.


The statistics of gamma conditionally Gaussian (CG) random variables are derived in closed form. These variables can be loosely defined to be normally distributed with mean and variance proportional to a gamma random variable. In this paper, we provide exact expressions for the bit error rate (BER) for single relay maximum likelihood (ML) decode and forward (DF) cooperative systems in Nakagami-m fading for binary phase shift keying (BPSK). This is done by expressing the ML decision variable in terms of functions of gamma CG random variables. For the piecewise linear (PL) approximation to the ML detector, a closed form expression for the BER is obtained. Simulation results are provided to verify the validity of the derived analytical expressions.

Rheumatic heart disease is the commonest cardiac disease complicating pregnancy in developing countries.Heart disease accounts for 15% pregnancy related mortality. In the presence of maternal heart disease, the circulatory changes of pregnancy may result in exacerbation of the haemodynamic perturbations due to complex cardiac valvular lesions.Determining the ideal anesthetic technique for Caesarean section in presence of such cardiac conditions remains a much debated topic. General anaesthesia is associated with a further increase in pulmonary pressure in response to laryngoscope and intubation along with myocardial depression by anaesthetic agents. Neuraxial blockade may lead to decrease in SVR and Cardiac output. In this article we present the successful anaesthetic management of a thirty parturient suffering from Rheumatic heart disease with mitral stenosis under epidural anaesthesia with good maternal and neonatal outcome. Successful management requires vigilant perioperative monitoring and thorough knowledge of the haemodynamics of cardiac valvular disease.


The objective of this case study was to develop and test a specific survey protocol for monitoring tensile forces for winch-assisted harvesters and forwarders with a mounted or integrated constant-pull capstan winch technology. Based on the designed survey protocol, the interactions between work phases, machine inclination, and tensile forces in typical work conditions were analysed. The established workflow, including equipment and the developed analysis routines, worked appropriately and smoothly. The working load on the cable during the study did not exceed 50% of the maximum breaking strength. A maximum tensile force peak at 56 kN was observed during delays for the forwarder, and a peak of 75.5 kN was observed for the harvester, both of which are still within the safe working load when considering a safety factor of two.


A consistent finding in our studies of auditory localization in rooms has been that brief tones with abrupt onsets and offsets are localized far more accurately than are sustained tones with slow onsets [W. M. Hartmann, J. Acoust. Soc. Am. 74, 1380–1391 (1983); B. Rakerd and W. M. Hartmann, J. Acoust. Soc. Am. Suppl. 1 75, S88 (1984)]. The purpose of the present study was to explore the contribution of signal onset rate to this effect. In a room with left‐wall acoustical reflections of brief delay (mean delay time = 1.5 ms), we assessed localization performance for sustained tones (500 Hz, 60 dB) with onsets of 5000, 1000, 500, 100, 50, 10, 5, and 0 ms. The accuracy of subjects' (n = 4) localization judgments increased monotonically with rate for all onsets less than 100 ms. Testing with a subset of the onset times showed that a similar pattern of results is obtained in rooms with other paths of reflection (ceiling, mean delay = 1.5 ms) and with other delay times (left wall, mean delay = 9 ms). We hypothe...
