Objective To evaluate the effect for the combination application of small dose of spironolactone metoprolol in the treatment of chronic heart failure.Methods 68 cases of patients with chronic heart failure were randomly divided into two groups,the test group and the control group,and 34 cases in each group.The control group was received basic treatment plus service metoprolol,and the experiment group was taken with spironolactone associated with metoprolol treatment.The change of cardiac function in patients was taken for evaluation with NYHA class standards before enrollment and drug classification change after four courses.Taking chemiluminescence for the detection of NT-proBNP values and patients were taken for echocardiography examination records on left ventricular ejection fraction(hereinafter referred to as the ejection fraction,EF).Results After four courses of treatment,the efficiency and total efficiency of heart function of the test group was significantly higher than that in the control group(P 0.05).Compared with the first two groups before treatment,the ejection fraction was significantly increased,while the NT-proBNP substantial declined.The serum NT-proBNP in the experiment group after four months was significantly lower than the control group,the cardiac ejection fraction was slightly higher than that in control group.Conclusion Spironolactone metoprolol can effectively improve the metoprolol treatment of chronic heart failure.


Abstract Home-based transactional services such as teleshopping have become available using videotex technology. In this form of shopping, users may acquire details of goods, evaluate items available and place orders by using a home terminal or an adapted television set. Two experiments examined different sorts of demand that the videotex ordering task might impose on users. The first experiment assessed the usability of four types of 'response frame' for practised users. Fastest performance times were associated with 'tailored' and 'menu' frames when ordering single items, and with 'tailored' and 'generalized' frames when ordering several items. The novel task structure associated with the 'generalized' response frame is different from normal shopping and therefore might be a source of difficulty for the novice user. A second experiment manipulated possible methods of increasing compatibility. Subjects given videotex-compatible experience were faster in ordering goods than subjects who only had 'shop' sh...


A novel gamma-ray imaging system is demonstrated, by means of Monte Carlo simulation. Previous designs have used either a coded aperture or Compton scattering system to image a gamma-ray source. By taking advantage of characteristics of each of these systems a new design can be implemented that does not require a pixelated stopping detector. Use of the system is illustrated for a simulated radiation survey in a decontamination and decommissioning operation.


The problem of getting irreducible *‐representations π of Lie superalgebras B(0,n), n=1,2, is studied, starting with a recently constructed family of linear representations in terms of differential operators on the space C∞N of CN ‐valued C∞ ‐functions. Equivalent formulation via creation‐annihilation operators of a para‐Bose system with n degrees of freedom is used, and the domain D of any π is shown to be a subset of C∞N containing a nonzero vacuum subspace. By assuming its dimension finite, the necessary conditions for existence of π are derived. The method is applied to the superalgebra B(0,1) and a one‐parameter family Π of nonequivalent irreducible *‐representations in terms of unbounded linear operators on L2(R+)⊗C2 is obtained. Each representation π∈Π has a nondegenerated vacuum and for all z∈B(0,1) satisfying z=z*, the operators π(z) are essentially self‐adjoint.


Eve Harrington's (Anne Baxter) outrageous deception might form the dramatic core of Joseph L Mankiewicz's 1950 satire 'All About Eve', but she is far from the only character to perpetrate - and suffer from - delusion. With a Shakespearean prowess for apportioning blame, Mankiewicz places Eve at the centre of a community in which few are to be trusted and the lines between appearances and reality are blurred. Her ruthless ambition is not only enacted through her own manipulations, but also enhanced by the dishonesty and jealousy of others - much like that of Othello's Iago. Nearly everyone is culpable, from the characters who practise minor deceits in their relationships, to those who tell outright lies, to those who fool themselves, to fickle audiences obsessed with fame and glamour.

The Dynamic Host Configuration Protocol for IPv4 (DHCPv4) has been
extended with a Leasequery capability that allows a client to request
information about DHCPv4 bindings. That mechanism is limited to
queries for individual bindings. In some situations individual binding
queries may not be efficient, or even possible. This document expands
on the DHCPv4 Leasequery protocol to allow for bulk transfer of DHCPv4
address binding data via TCP.

In this paper we present a short description of "BRITA in PuB...


Air pollution has been recognised as one of risk factors that exert adverse effect on human health, climate change and environmental deterioration. Since particulate matter less than 10μm (PM10) is used as an important air quality indicator in Malaysia, it is crucial to map the PM10 spatial distributions especially over Malaysian cities which encounter higher pollutant concentration due to trans-boundary and local sources. PM10 has been widely estimated using satellite data but the coarse resolution of 10km tends to average out the spatial variation especially in cities. Therefore, in this study we tested the Aerosol Optical Depth (AOD550) product from Moderate Resolution Imaging Spectrometer (MODIS) sensor at 3km to estimate PM10 concentration over Peninsular Malaysia. The performance of AOD550 at 3km product was validated with AOD retrieved from AERONET stations and an accuracy of R2 = 0.58 and RMSE = 0.13 was obtained. PM10 was estimated over the cities for the period 2007-2011 using MODIS AOD550 and meteorological variables (surface temperature, relative humidity, atmospheric stability, wind speed, wind direction). In consideration of their complicated relationship and non-linear mechanism that may exist between the variables artificial neural network (ANN) technique was utilized to develop an empirical model to estimate PM10 concentrations. Result shows that the empirical model developed using ANN was moderately robust with R2 of 0.41 and RMSE = 12.99 μgm-3. However, PM10 estimated with the model over the cities was validated using an independent set of field data produced an acceptable accuracy with R2 = 0.39 and RMSE = 10.95 μgm-3. The inclusion of meteorological parameters improved the prediction and the result obtained allow us to map pollution levels in Malaysia.

Tolypocladium nubicola separated from soil is new to China. Its characters are as follows. Colonies on Czapek agar are flat, attaining a diameter of 30 mm to 35 mm within 14 d at 25℃. Phialides directly arise from aerial hyphae or simple conidiopore, proliferating. Phialides are mostly (2.6~7.2) μm×(1.3~3.2) μm, consisting of an ellipsoidal or globose basal portion, tapering into a distinct and often bending neck,(3.0~6.3) μm long and 0.3 μm wide. Conidia are solitary, cylindrical to ellipsoidal,(1.6~3.8) μm×(0.8~1.2) μm, without slime layer.


According to WHO, it is estimated that there were 88,000 diabetics in Libya the year 2000. This prevalence is estimated to reach 245,000 diabetics by the year 2030, (see figure below). In Libya, according to local epidemiological studies, the prevalence for known diabetic patients aged over 20 years was 3.8% [2]. As 50% of type 2 diabetic patients are unaware of their diabetes "undiagnosed", the actual prevalence is probably higher. In the town of Tajoura, the west part of Libya; 7.9% of all adult members of 1094 randomly selected families (2996 persons aged between 20 and 75 years) had diabetes [3].


Introduction: The aim of this study is long term comparison of hydroxyapatite (HA) coating and porous (PO) coating in an identical stem design. Material and Methods: 100 consecutive hips from 86 patients scheduled for uncemented primary arthroplasty were quasi-randomized to receive a titanium-alloy anatomic PROFILE stem (DePuy, Warsaw, IN), HA coated in every second hip and PO coated in the remainder 50 hips. Patients receiving bilateral total hip arthroplasty were implanted an HA coated stem in one and a PO coated in the contralateral hip. All surgeries were performed by the posterolateral approach by 2 surgeons (the author PBT being one of them). The acetabular component was either an AML+ or a Duraloc 300 implant with a cobalt chrome 28mm head (DePuy, Warsay, IN). 15 to 18 years postoperatively these patients and their hip radiographs were examined by an independent observer (WD) to establish the long term survival, clinical and radiographical performance of this stem and especially to compare the two coatings. The Harris hip score was employed for clinical evaluation Results: 16 years and 3 months (range 15y 0m – 17y 8m) postoperatively 21 patients with 23 hips had died and 4 hips (2HA/2 PO) had been revised. This leaves 62 patients with 73 hips (34 HA/39 PO) for evaluation. Life tables showed 18 years cumulative survival (free of revision of any reason) of 95.8% for HA and 95.5% for PO. 18 years cumulative survival (free of revision for aseptic loosening) were 95.8% for HA and 97.5% for PO. There were no infections in either group. Mean HHS was 83.4 ± 14.8 in HA and 86.8 ± 11.5 in PO (P = 0.32). Mean pain score was 39.1 ± 9.4 in HA and 40.9 ± 6.7 in PO (P = 0.69). Radiographs showed osseointegration of the stem except in 1 HA and in 2 PO stems. Lucencies/osteolytic scalloping were only seen in zone 1 and 7. Significant bone remodeling changes were seen. Ectopic ossification developed in 1/3 of hips non progressive stem subsidence of 2 mm were measured in a few hips. Conclusion: This prospective quasi-randomized study show excellent long term performance and survival of the titanium-alloy anatomic PROFILE stem in primary hip arthroplasty in patients


BACKGROUND
 Population aging is a global phenomenon, with the proportion of the population over the age of 60 increasingly rapidly. It is essential to gain understanding of the factors that influence acceptance of these technologies when they are introduced as part of the monitoring and management of clinical conditions.

 OBJECTIVE
 This study undertakes semi-structured interviews of elderly patients being monitored for COPD, CHF or diabetes to determine the factors they deemed most important for acceptance of the technology.

 METHODS
 18 women and 12 men with age range 65-90 and mean 77 years were interviewed.

 RESULTS
 Nine main themes emerged; attitude to aging and illness, coping strategy, relationship and support, patient-doctor interaction, incorporating patients, self-efficacy, personality, personal meaning, and knowledge. The themes were grouped to three constructs; age/illness, patient, and healthcare practitioner, that were considered as the basis of a framework for a patient technology acceptance model (PTAM).

 CONCLUSIONS
 An extended model of TAM emerges that describes the behaviour of elderly patients towards adoption of technology to monitor their health.

Key words:
Arteriosclerosis ;  Carotid artery intima-media thickness ;  Hyperuricemia ;  High sensitivity C-reaction protein ;


The Hungarian-born Jewish director and playwright George Tabori (1914-2007) grappled three times with The Merchant of Venice. However, none of his productions was a faithful rendering of the Shakespearean text. Inspired by the arcane figure of Shylock, Tabori downplayed the main plot in favour of focusing on the Jew. Among modern-dress adaptors of the play after the Shoah, Tabori was one of the first to place Shylock's story in the context of the Holocaust, claiming that it is impossible to »do Shylock totally ignoring what has happened«. Tabori's first staging was tellingly entitled The Merchant of Venice as Performed in Theresienstadt. Presented in Massachusetts in 1966, the play was set in a concentration camp with Jewish prisoners performing for a Nazi audience. Twelve years later, in 1978, Tabori dispensed with the Belmont plot, offering his German audience in Munich Improvisations on Shakespeare's Shylock. a provocative and deeply disturbing performance highlighting Diasporic histories of anti-Semitism. Finally, in 1989, Tabori included an episode from the play in his Shakespeare collage Lovers and Lunatics. Playing the part of the long-suffering Jew, his Shylock was the ahistorical embodiment of the old narrative of friction and distrust between Jews and Christians.


As the integration of DC distributed resources increases in recent years, hybrid AC/DC topology emerges as a promising alternative in the planning of distribution systems. This article presents an AC/DC optimal expansion planning of distribution networks from Distribution System Operator's perspective with a special focus on grid architecture through Integer Programming-based topological constraints. The proposed formulation aims to determine the optimal location and sizing of converters and to select lines type (AC or DC) and state (closed or open). The problem is formulated as a mixed integer second-order conic programming model that guarantees global optimality and verifiable exactness by using off-the-shelf solvers. A multi-scenario approach with a Wasserstein distance-based scenario reduction is applied to deal with resource uncertainty. Case studies based on a 13 bus and IEEE 33 bus distribution networks were used to verify the effectiveness of the model. The results show that a hybrid architecture can improve the efficiency of the grid through optimal active power flow and reduce the total network costs.


BACKGROUND
Kaposi sarcoma (KS) in people living with HIV (PLHIV) is the most common acquired immunodeficiency syndrome (AIDS)-associated malignancy. There is increased interest in KS in PLHIV with controlled HIV viremia.

OBJECTIVES
To describe KS occurring in PLHIV despite virological control and to compare their clinical presentations with viremic AIDS-KS and classic KS (CKS).

METHODS
This was a monocentric retrospective study, including all KS patients registered between the 1st January of 2000 and 31st of December 2017 in a comprehensive data bank for all cancers in the Hérault region, South of France. AIDS-KS were also described using chart reviews from the Infectious diseases Department, which followed more than 90% of PLHIV from the same region. We defined aviremic AIDS-KS as KS occurring in persons taking HAART with a HIV viral load <50 copies for more than 12 months. We compared clinical characteristics of persons with aviremic AIDS-KS, viremic AIDS-KS and CKS, using the Kriegel score and number and topography of skin lesions, and presence of lymphedema.

RESULTS
We retrieved 187 KS cases, of which 12 occurred in PLHIV with aviremic AIDS-KS. Kriegel score stage I was found in 10 (83%) of the aviremic AIDS-KS, 34 (68%) of CKS and 38 (58.4%) of viremic AIDS KS cases, with similar clinical presentations between aviremic AIDS-KS and CKS groups, and viremic AIDS-KS subjects having more aggressive presentations. One person with aviremic AIDS-KS had visceral involvement.

CONCLUSIONS
we showed that KS in PLHIV with controlled viremia were generally indolent, similarly to CKS. Visceral involvement is however possible.

To straighten the true relationship between the practice and history implied by materialist conception of history relies on the clarification of the meaning of "history" in that materialist conception of history.Yet,the notion of history is based on the concept of time.Due to the close relations between Marxist and Hegelian Philosophies,it is natural for people to transplant the Hegelian concept of time into the philosophy of Marx,thus neglecting the great differences between the two in this aspect.When Althusser interpreted Marxism according to structuralism,scholars,one after another,accused him of leading Marxism into anti-historicism,but failed to discern the active implication of the heterogeneous time and theoretical history in his theory.In reality,it is just via Althusser that we have managed to realize that the history of Marxist philosophy is based on the dialectical unity between the theoretical history and experiential history on the foundation of the dialectical unity between the heterogeneous time and the homogeneous time.


Editor,—Foveal relocation surgery for the treatment of subfoveal choroidal neovascularisation (CNV) secondary to age related macular degeneration (AMD) has received significant publicity in the lay press and has given rise to some controversy reported in the BJO .1 We describe the 12 month follow up of a case reported in the press in December 1998.

A transfer matrix method is developed for the analysis of nonlinear waveguides with Bragg gratings. In our numerical model, the nonlinear refractive-index change resulting from the optical field along a grating structure is taken into consideration. This method can be applied to the study of a wide range of nonlinear phenomena in different grating structures. We have analyzed the nonlinear responses of optical signals at the Bragg wavelength as well as other wavelengths. We show that a small change in the refractive index can cause a significant change in the optical-field distributions along the grating and also the transmission response.

Objectives: Metabolic syndrome is correlated with increased cardiovascular risk and char-acterized by several factors, including visceral obesity, hypertension, insulin resistance, and dyslipidemia. Several members of a large family of nonselective cation entry channels, e.g., transient receptor potential (TRP) melastatin 7 (TRPM7) channels have been associated with the development of cardiovascular diseases. The purpose of this study was to inves-tigate the effects of Dangkwisoo-san, ginger and curcumin on TRPM7 channel. Methods: Human embryonic kidney (HEK) 293 cells stably transfected with the TRPM7 ex-pression vectors were maintained in Dulbecco's modified Eagle's medium (DMEM) supple-mented with 10% fetal bovine serum (FBS), 1% penicillin/streptomycin, 5 µ g/mL blasticidin, and 0.4 mg/mL zeocin in a humidified 20% O 2 /10% CO 2 atmosphere at 37℃. Whole-cell patch clamp recordings were obtained using an Axopatch 700B amplifier and pClamp v.10.4 software, and signals were digitalized at 5 kHz using Digidata 1422A. Results: Dangkwisoo-san extract (100, 200, 300, 400, and 500 µ g/mL) inhibited the outward and inward TRPM7 whole-cell currents at dose dependent manner and the half maximal inhibitory concentration (IC) 50 of Dangkwisoo-san was 218.3 µ g/mL. Also, ginger extract (100, 200, 300, 400, and 500 µ g/mL) inhibited the outward and inward of TRPM7 whole-cell currents in a dose dependent manner and the IC 50 of ginger was 877.2 µ g/mL. However, curcumin had no effects on TRPM7 whole-cell currents. Conclusions: These results suggest that both Dangkwisoo-san and ginger have good roles to inhibit the TRPM7 channel, suggesting that Dangkwisoo-san and ginger are considered one of the candidate agents for the treatment of metabolic syndrome such as cardiovascular disease.


— The coefficients of thermal expansion and contraction of several dental addition silicone impression materials have been measured and their importance for precision of impressions recorded. Dies were made from impressions following: (1) cooling to 22 °C for 15 min, (2) cooling to 22 °C for 15 min and heating to 37 °C for 15 min, (3) holding for 24 hr at 22°C, and (4) storing for 24 hr and then heating to 37 °C for 15 min. The results show that a reheating of the impressions to mouth temperature before die casting reduces their inaccuracy significantly.

This chapter begins by considering the especially severe information-asymmetry problem that plagues primary offerings of truly new securities. It then examines market-based solutions for these problems, the shortcomings of exclusive reliance on such solutions, and the rationale for having a government-designed affirmative-disclosure regime, whereby an issuer making an offering is required to answer certain questions. It also addresses the question of whether this regime should be imposed on all issuers making such offerings or only those that volunteer to be subjected to it. The remainder of the chapter considers the rationale for mandating the imposition of liability on issuers, issuer directors and officers, underwriters, dealers, and experts such as accountants or rating agencies when there have been material misstatements or material omissions of what was required to be disclosed. The final section briefly applies the preceding discussion to the efforts, as part of the Capital Markets Union, to increase the opportunities for European SMEs raise funds through public offerings.


Anatase TiO2 nanocrystals (aTiO2) of a uniform size have been synthesized and were subject to a successive hydrogenation under a H2 gas flow at elevated temperatures (500–700 °C). We found that the concentration of Ti3+ defects, such as Ti3+ interstitials and oxygen vacancies, and their distribution between surface and bulk varied significantly, depending on the hydrogenation temperature and time. Such changes in defects were found to be critical in enhancing the photoactivity of the hydrogenated TiO2 (H-aTiO2) by an order of magnitude. In our case, H-aTiO2 nanocrystals hydrogenated at 600 °C for longer than 10 h showed 10 times higher photoactivity than aTiO2, which was explained from a high surface-to-bulk defect ratio and a nonuniform distribution of defects between bulk and surface due to a preferential diffusion of bulk defects to the surface. Our study showed that a kinetically controlled hydrogenation condition could be used not only to control the surface/bulk defects but also to enhance the photo...


Bone marrow stromal cell antigen 2 (BST-2, also known as tetherin/CD317/HM1.24) is an interferon (IFN)-inducible membrane protein with a potential role in innate immunity against virus infection. BST-2 has recently been identified as a host restriction factor for diverse families of enveloped viruses including retroviruses, filoviruses, arenavirus and herpesvirus. In theory, any lipid-enveloped virus could be restricted by BST-2. However, BST-2 antiviral activity against hepatitis C virus (HCV), a lipid-enveloped RNA virus, has not yet been studied. Here we demonstrate that human hepatic cell line Huh7.5.1 expresses a low level of BST-2. However, robust expression or induction of BST-2 in Huh7.5.1 can be elicited upon stimulation with IFN-α, IFN-γ or both. Over-expression of BST-2 by either interferon treatment or BST-2-expressing plasmid DNA transfection suppressed culture-type infectious HCV (JFH1) production in Huh7.5.1 cells. In addition, shRNA-mediated depletion of endogenous BST-2 resulted in enhanced HCV production. Our results have demonstrated a previously unknown anti-HCV activity of BST-2, and have also identified BST-2 as a host restriction factor against HCV infection. These results indicate that the induction of BST-2 in hepatic cells could be one of the mechanisms by which current HCV standard therapy (IFN-α plus ribavirin) achieves a sustained virological response. Our data also point out a novel therapeutic strategy to control HCV infection.


Petrophysical, rock magnetic and anisotropy of magnetic susceptibility (AMS) measurements have been carried out on a porphyry type Cu-Au deposit in Kedonojankulma, on an orogenic gold deposit in Uunimäki and on the exploration target of Mäyrä in the Palaeoproterozoic Häme belt of Southern Finland. The mineralizations occur in strongly altered and sheared zones. The main aim of the laboratory studies has been to identify and characterize ore-related alteration processes that are reflected in the physical properties of rocks. The studies have focused on magnetic properties and the identification of magnetic minerals using rock magnetic tests. Magnetic mineralogy was verified by SEM studies. In the Kedonojankulma quartz-plagioclase porphyrite occurrence, the induced and remanent magnetizations are slightly higher in the altered auriferous shear zone than in the less altered host rock. In the altered zone, the only magnetic mineral is monoclinic pyrrhotite with a high Curie temperature, while in the host rock the main magnetic mineral is ilmenite with minor magnetite. In the Uunimäki gabbroic occurrence, the highest magnetization values correlate with strong IP anomalies, the magnetization being carried by monoclinic pyrrhotite with a high Curie temperature. In the more weakly magnetized rocks, the magnetization predominantly resides in ilmenite. In the strongest IP anomaly area, which is also regarded as the most gold bearing, the remanent magnetization also has strong intensity, and a Svecofennian age remanence could be isolated. The result thus suggests that provided that gold and pyrrhotite are contemporaneous at the site, the gold is post-tectonic. Based on AMS data, the magnetic foliation planes follow the general foliation structures in both formations, although the degree of anisotropy varies considerably. In the Mäyrä occurrence, the magnetization of the shear zone has decreased due to hydrothermal alteration. The surrounding gabbros, whether coarse-grained dark gabbro or fine-grained lighter coloured gabbro, contain magnetite as the main magnetic mineral, while the shear zone also contains pyrrhotite in addition to magnetite.


Two separate nonlinear difierential systems are investigated in the frequency and time domains using plots generated by Mathematica. Spectral density plots are of particular interest as they can conveniently demonstrate the efiect on a system of changing one of the parameters. The efiects of the starting displacement on the nonlinear pendulum, and the behaviour of the Lorenz system when the Rayleigh number is varied, are considered in this way.


The financial crisis is a problem faced by all human beings, including Christian children. As a result of Covid-19, the economic recession and the decline in the selling value of goods have caused financial problems to get worse. In responding to this problem, a church strategy is needed in the religious sphere to overcome the psychological impact on the congregation. This research aims to determine the service strategy for the Bethel Indonesia Kasih Church congregation to the congregation experiencing the financial crisis. The research method used is phenomenological qualitative with data collection techniques through interviews and observations. The results of the study indicate that the forms of pastoral vocation that can do by church counselors to overcome the congregation's financial crisis are (i) strengthening the congregation's faith in God's providence; (ii) teaching a positive attitude in viewing the financial crisis; (iii) preparing a forum for entrepreneurship; (iv) provide job opportunities for counselees; (v) teach about being a good producer.


AbstractGrey cast iron has been regarded, in some circles, as being brittle, low in reliability and one where the usual design equations cannot be applied. The reason is usually attributed to the presence of randomly distributed graphite flakes. This presentation discusses, both experimentally and theoretically, the notch strength, bending strength, and the scattering of tensile strength of grey cast iron, and suggests a new approach based on plasticity theory for the accurate evaluation of these characteristics. Experiments showed that grey iron has a very low notch sensitivity in circumferentially notched bars, but that strength decreases in edge-notched plates. At the temperature of liquid nitrogen, notch sensitivity is very high. In ductile iron, strength increases in notched specimens. These results have been interpreted by the stress distribution, taking into account non-elastic stress/strain behaviour, and using a fracture criteria with an over-stressed depth, δ· The δ is a necessary region for fra...


The genus Miogryllus includes a considerable number of species, most of them still undescribed. From those already described, the amount of afforded details on morphology is not always enough to recognize the species, missing information on phallic and pars stridens structures as well as karyology. The present paper aims to improve these information, on the species M. piracicabensis.


Implementation of complex computer circuits assembled from the bottom up and integrated on the nanometer scale has long been a goal of electronics research. It requires a design and fabrication strategy that can address individual nanometer-scale electronic devices, while enabling large-scale assembly of those devices into highly-organized, integrated computational circuits. We describe how such a strategy has led to the design, construction, and demonstration of a nanoelectronic finite-state machine (nanoFSM). The system was fabricated using a design-oriented approach enabled by a deterministic, bottom-up assembly process that does not require individual nanowire registration. This methodology allowed construction of the nanoFSM through modular design employing a multi-tile architecture. Each tile/module consists of two interconnected crossbar nanowire arrays, with each cross-point consisting of a programmable nanowire transistor node. The nanoFSM integrates 180 programmable nanowire transistor nodes in three tiles or six total crossbar arrays, and incorporates both sequential and arithmetic logic, with extensive inter-tile and intra-tile communication that exhibits rigorous input/output (I/O) matching. Our system realizes the complete 2-bit logic flow and clocked control over state registration that are required for a FSM or computer. The programmable multi-tile circuit was also re-programmed to a functionally-distinct 2-bit full adder with 32-set matched and complete logic output. These steps forward and the ability of our new design-oriented deterministic methodology to yield more extensive multi-tile systems, suggest that proposed general-purpose nanocomputers can be realized in the near future. of observed beyond 15 h, is largely due to changes in individual transistor (e.g., hermetic programmable


Economic crime is a kind of crime which destroys the order of socialistic market economy of our country. It not only seriously damages the order, but also influences fundamentally the overall situation of our current reform, development and stability. In the course of cracking this crime, to probe the realistic and scientific investigative countermeasure of economic crime is of great significance to improve the level of criminal investigation and control it forcefully.


Abstract –A chromoprotein fraction was isolated from the freshwater dinoflagellate, Peridinium gatunense, which is assumed to contain the photoreceptor chromoproteins for phototaxis, as its absorption and fluorescence spectra correspond to the action spectrum for phototaxis. The chromoproteins of this fraction were separated by anion‐exchange column chromatography and further by sodium dodecylsulfate gel electrophoresis.


After reviewing the evidence for weak simultaneous occurrence of one exclusive and one inclusive pomeron, experiments are described that seek two exclusive pomerons, as well as two exclusive and one inclusive. We discuss the theoretical basis for expecting weak but indefinite pomeron recurrence as the energy increases and outline a systematic rapidly‐converging fireball expansion that brings order to a confusing picture. The widely‐employed two‐component model of particle production corresponds to the two leading terms. An experimentally meaningful concept of "bare" pomeron emerges naturally from the fireball expansion, as does the notion of pomeron renormalization and splitting (the schizophrenic pomeron).

This inquiry explores images of women from mortuary contexts of China's Han dynasty (206 BC–AD 220). These early images are generally regarded as static illustrations that served to frame deceased individuals and define their social position and moral values. Recent research, however, has suggested that artisans were also interested in conveying images for visual pleasure, and were thus attentive to details, particularly of hairstyle and dress, that expressed ideals of female beauty. Close study of a hairstyle common to images of Han women, which comprised a bun with a single lock of hair trailing out, alongside changes in clothing styles across the period's historical divisions indicate a growing preference for volume and fluidity in presentations of the adorned body. It is demonstrated that the trailing lock is visually and figuratively aligned with clothing styles to enhance silhouette. Moreover, the stylistic dialogue between hairstyle and clothing served as a significant indicator of a woman's grace and comportment, facets of beauty that are often overlooked for early China. Finally, such changes are understood against an historical atmosphere where a more fluid and dynamic aesthetic was increasingly favoured.

Multi-nutrients deficiency of soil in southwest Ethiopia is among the primary constraints for the very low productivity of potatoes (Solanum tuberosum L.). The combined use of organic and inorganic fertilizers is vital for resolving the common productivity issue. Thus, experiments were performed on potato variety "Belte" in Masha district, southwestern Ethiopia, in both Belg (February to May) as well as Meher (June to October) seasons of 2019 to evaluate the potato response to the vermicompost, mineral phosphorus, and nitrogen's integrated applications. The experiment had three vermicompost rates with the factorial combination (2.5, 5, 7.5 t/ha) and three recommended rates inorganic NP's 25%, 50% and 75% (124 kg N/ha and 103 kg P2O5/ha) fertilizer. Results have discovered that 75% inorganic NP and 7.5 t/ha vermicompost's combined application significantly increase total tuber yield, marketable tuber yield, and individual tuber weight, giving the maximum net benefits and marginal return rate. Thus, it has been discovered from this work that for potato production at Masha area, 7.5 t/ha vermicompost with inorganic NP's 75% recommended dose's combined applications are best-integrated nutrient management options.


A recent edition of the The Lancet described the increasing prevalence of hypertension amongst children and adolescents in lowand middle-income countries (LMICs) as 'most disturbing'. The article, which was part of an issue focusing on hypertension, also commented on the strong association between obesity and childhood hypertension in these countries. However, for many LMICs, action to reduce hypertension is hampered by the lack of national or local data. In all likelihood this means that children with significant hypertension will remain undiagnosed and untreated. Perhaps more importantly in population terms, this will also mean absence of the preventive programmes which could provide first-line treatment for undiagnosed cases of mild hypertension as well as reduce the risk for those so far unaffected. Thus Schwiebbe et al.'s paper in this edition of Paediatrics and International Child Health is to be welcomed since it describes overweight/obesity in more or less the whole schoolchild population of the Caribbean island of Bonaire and then compares the blood pressures of overweight/obese children with those of matched controls. Not surprisingly, overweight/obesity was found to be very common and the prevalence of hypertension was significantly higher in the overweight and obese groups. This was true even in the group of children below 10 years of age in whom hypertension might normally be considered unusual. This is undoubtedly a most disturbing situation. The findings in Schwiebbe et al.'s paper contrast with those in another study of hypertension in children from Port Harcourt, Nigeria by Okoh et al. also published in this edition. This latter study assesses children only up to the age of 12 years but finds a prevalence of hypertension noticeably lower than on Bonaire. Okoh et al. measured blood pressure using auscultation rather than an oscillatory method which might result in slightly lower prevalences of hypertension but should not account for the degree of difference between the studies. Remarkable, however, is the difference in the prevalence of overweight/ obesity in the two populations and this highlights the point made by both studies but particularly the Bonaire study, that obesity/overweight is a major association of hypertension even in children. Okoh et al. also found more prevalent hypertension in the youngest 5–8 years old age group than in those aged 9–12 years but explain this difference, which was not statistically significant, as possibly due to a prevalence of 17.2% of overweight/obesity in the youngest children compared with 7% overweight/obesity in the older age group. Whether this difference is relevant or not, it is clear that elevated blood pressure is not uncommon in both these study populations and that overweight/obesity is a significantly associated factor. The usually silent presence of hypertension in children, although a serious marker for later cardiovascular disease, should be a matter for concern for paediatricians and all those involved in community child health. When hypertension is recognised, advice can be given and, if necessary, therapy prescribed but without blood pressure measurement hypertension will remain disturbingly overlooked. It is unlikely that progress on developing preventive action for hypertension in LMICs will be implemented without prior studies into prevalence of the problem in the nations or communities under consideration. Population studies of blood pressure in childhood in LMICs may be few in number because hypertension is not perceived as a significant problem or, at least, not as a problem with its origins in childhood. However, the difficulties of carrying out large, reliable studies in children might also discourage efforts in this area. Children require extra attention with regard to the actual measurement of blood pressure and in the interpretation of findings. Anxiety over the presence and pressure of a cuff around the arm and about the environment in which the blood pressure is being recorded can create sufficient stress to elevate the blood pressure. Furthermore, the variable size of the upper arm, even with children of the same age, presents a major problem for those deciding the size of cuff appropriate for each child. A cuff that is too narrow or too short for the Correspondence to: E M E Poskitt, 11 Hedge End, Woodstock, Oxfordshire OX20 1NP. Email: firstname.lastname@example.com


Temperature is the main factor that influences the output characters of fiber optic gyroscope (FOG), and high accuracy FOG is special the same. In order to reduce the influence of gyro accuracy, a small temperature control system is designed in the paper. In the system, platinum resistor is used as measuring element, semiconductor refrigerator is used as new temperature control element, realizing high accuracy temperature control. The experiments show that high accuracy temperature control of FOG can improve the heat environment of inertial instrument, improving synthesis performance of FOG. This system also provides a practical method for FOG system entering stable working status rapidly, also supplying good reference for similar inertial measuring combination of temperature control system.


Timolol maleate (TM), a beta-adrenergic receptor antagonist, is widely used for canine antiglaucoma eye drops; however, its bioavailability is <5%. Our previous study revealed that magnesium hydroxide nanoparticles (nMH) have potency in improving the bioavailability of fixed-combined TM in rodent models. This study aimed to investigate whether the fixed combination with nMH improves the ocular hypotensive effect of TM and affects pupil size (PS), heart rate (HR), and mean arterial pressure (MAP) in clinically healthy dogs. Five clinically healthy dogs were administered topical saline, commercial 0.5% TM, and a 0.01% or 0.1% nMH–0.5% TM fixed combination (0.01% or 0.1% nMH–TM) twice daily in one eye for 7 days with at least a 28-day interval. The changes from baseline were calculated and were statistically analyzed for each drug. IOP was significantly reduced in both 0.01% and 0.1% nMH–TM-treated-dogs compared with saline- and TM-treated dogs. Meanwhile, 0.01% and 0.1% nMH did not exacerbate the side effects of TM. From these results, nMH improved the ocular hypotensive effect of TM without enhancing side effects. Topical nMH–TM is potentially more effective for canine ocular hypotensive eye drops than TM.


SUMMARY

In the course of their development the protonemata of Funaria hygrometrica produce two different substances which diffuse into the substrate. In the chloronema a thermo-labile growth-promoting substance is formed. In the caulonema, after about 10 days, a substance is produced which is thermostable and soluble in amyl alcohol, which can be dialysed, and which functions as a growth inhibitor. Both substances also influence bud formation. This is at an optimum only when there is a certain balance between these two substances.

This promotion is fundamentally different from that brought about by treatment with kinetin, because kinetin can function only as an additional factor in promoting bud formation. Very probably it acts as an agent which creates centres of attraction toward which morphogenetic substances are drawn. This assumption is supported by the fact that kinetin cannot be transported and therefore has no 'after-effect'. It probably functions only in the caulonema cell it penetrates. It converts every caulonema cell into a 'reaction cell'.


Rotating detonation engines (RDE's) represent an alternative to the extensively studied pulse detonation engines (PDE's) for obtaining propulsion from the high efficiency detonation cycle. Since it has received considerably less attention, the general flow-field and effect of parameters such as stagnation conditions, combustion chamber length, and fuel mixture on specific impulse are less well understood than for PDE's. In this paper we develop a model for doing time-accurate calculations of RDE's in two and three dimensions, using algorithms that have successfully been used for PDE simulations previously. Results are shown for a stoichiometric hydrogen-air RDE operating at 10 atm, 300 K stagnation premixture conditions and 1 atm back pressure. Conditions within the chamber are described as well as inlet and outlet conditions and integrated quantities such as total mass flow, force, and specific impulse. Further computations examined the role of back pressure and inlet stagnation pressure on performance. It was found that the specific impulse was dependent on pressure ratio, whereas the mass flow and propulsive force were primarily dependent on the stagnation properties of the inlet micro-nozzles. The specific impulse varied from 3845 sec to 5560 sec over a pressure ratio of 5 to 30. The specific impulse for the 10 atm stagnation pressure, 1 atm back pressure was 5130 sec.

The article describes the procedure of constructing activation functions for wavelet-neural networks. This paper proposes an algorithm for synthesis of wavelets of a given shape for wavelet neural networks. A comparative analysis of different mathematical models of wavelets is conducted. Their complexity and possibility of application in the process of wavelet-neural networks design, modeling and implementation are estimated. The article demonstrates wavelet graphs obtained using these models. The main results indicate the possibility to use the wavelets derived from polynomial models to construct activation functions for these networks as well as the neural network and spline models proposed by the author. The final choice of the mathematical model is determined by the task to be solved and the available computational resource.


Literature produced around the notion of charisma (attributed to the chief, the master, the leader, the Father, the guru, the boss, etc.) has supplied, in the past, arguments for Nazi and Fascist propaganda (Cohen 2013; De Felice 1968). This seems clear by Hitler and Mussolini's great interest for Gustave Le Bon's The Crowd: A Study of the Popular Mind (1895), translated in English one year later (Le Bon 2001). How does Le Bon describe the absence of control, the exceptional character and the radical alterity of this crowd or "multitude" (Le Bon, 2001: 68)? In his major book, Gustave Le Bon - father of social psychology, in late nineteenth century - builds a visual theory of the crowd and a visual politics of charismatic domination. Nevertheless, we can conclude that Le Bon formulated a false hypothesis, based on a false effective appearance. As we have seen, Le Bon explains throughout his treatise, what are the characteristics of the "crowds", why do they need to be commanded by a charismatic chief, and how shall this chief behave, purposely using the visual to give a political form to the crowd, and to maintain the multitude under his control. The efficacy of visual representation is the means through which the dominant class can maintain his power. My hypothesis is that, following the use made after The Crowd by early twentieth century men of industry, liberal western statesmen, and European dictators -, Le Bon's thesis has worked as a self-fulfilling prophecy. Le Bon produces a strange relationship between belief and behaviour, where the content of the first shapes the second. Making Le Bon's theory of charismatic leadership a self-fulfilling prophecy, means not distinguishing between from one side, the political and visual imagination of a crowd, and, from the other side, the shaping of a crowd. Formulating clearly this distinction seems to be a necessary act of critique. Le Bon captures the fact that an affective dynamics constitutes the charismatic relationship between a chief and a crowd, but then denies the very same fact: if, according to the sociological observation, crowds are strongly imaginative and imagining, and the leader projects images, why the nature of this relationship, as a power relationship, is occulted? Not distinguishing between imagination of crowds and crowd moulding: this is how Le Bon's argument fulfils itself, as if it were the formula of a prophetic authority. It has already been said how Le Bon's theory has been used for purposes of propaganda, but it has not been explained why and how his hypothesis have been so successful, why it really has produced charismatic regimes, despite the fact that Le Bon denies, in fact, the heart of the very same hypothesis he carries on. Actually, there is an opposition between the political interest undermined by Le Bon's argument, and the fact that it is a hypothesis, an observation. The hypothesis is false, and the political interest denied, that's why it is so important to stress on the distinction raised by Yves Cohen. In Le Siecle des chefs, he immediately points the political effect of not distinguishing, in producing a naturalization of hierarchy. Therefore, Cohen suggests distinguishing between the interest for the chief and the need for a chief. How do Le Bon's visually produces this ambiguity, between " the way the observation is formulated (vocabulary) " and the way the same observation is " elaborated (sociological thesis) "?


EDITOR,--Active management of labour was introduced not with the intention of reducing rates of caesarean section but rather to reduce the incidence of prolonged labour.1 This it has done in the National Maternity Hospital, Dublin, and in most other studies without increasing rates of operative delivery—indeed, it has reduced this rate in some studies. …


Banded karyotypes of 50 species belonging to 23 genera were analyzed. The diploid chromosome numbers ranged from 26 to 50. For karyotypic comparison we used a 44 chromosomes karyotype, consisting of 4 metacentric and 17 acrocentric autosomes, as "basic karyotype". Almost all of its 25 autosomal arms could be identified in each individual karyotype. In 8 chromosomes, i. e. 1/2, 7, 11, 12, 13, 15, 23 and X, small inversions were detected. As a result, each of the chromosomes mentioned occurs in two states which differ slightly in their banding patterns. These were used as character states in the cladistic analysis together with other chromosomal rearrangements.

The implications drawn from the cladogram obtained are: The Miniopterinae clearly belong to the Vespertilionidae but are the first to branch off from the common stem. The tribe Myotini should be raised to the rank of a subfamily. Within the largest subfamily Vespertilioninae, one autapomorphic chromosomal character was found for each of the tribes Vespertilionini and Pipistrellini. In addition, both tribes are distinguished from the other Vespertilioninae tribes by two synapomorphic features. These results allow for the first time an unequivocal classification of the systematically difficult "pipistrelloid" species. The species of the genus Pipistrellus (sensu Hill and Harrison 1987) are spread over the Pipistrelllni and Vespertilionini. We therefore suggest the splitting of this heterogenous genus into at least four genera. Only the members of the previous subgenus Pipistrellus constitute the genus Pipistrellus and belong to the Pipistrellini. The previous subgenera Hypsugo, Vespadelus and Falsistrellus, given generic rank in some recent studies, belong to the tribe Vespertilionini and are not closely related to Pipistrellus. For the genera Eptesicus and Hesperoptenus, which belong neither to the Vespertilionini nor to the Pipistrellini, the tribe Eptesicini was established. The phylogenetic relations of this tribe and the status of the presumably polyphyletic tribe "Nycticeiini" could not be solved.

ABSTRACT As dominant group members, Whites tend to experience race as a low salience identity, particularly in interactions in White settings with other Whites. Using data collected from in-depth interviews with White partners in interracial relationships, this paper analyses what happens when Whites enter non-White settings and become racially marked. How do Whites understand the meaning of their Whiteness in these settings and what strategies do they use to manage others' impressions? White participants reported experiencing hypervisibility, a sharp awareness of their racial identity, and heightened apprehensions about being perceived as potentially racist and culturally inept. Consequently, participants made conscious changes to their behaviours (e.g. body language, food consumption), speech, and appearance as a means of signalling a "good" White identity and establishing belonging in spaces where they were marked as racial and cultural outsiders.


Radio galaxies are episodic in nature. In our recent work, our study of jet properties and their dynamics in different episodes of activity has revealed various hitherto unknown aspects of the extragalactic jets. We discover that the injection spectral indices are similar in the two different episodes for most of the episodic radio galaxies in our sample. We argue that in order to produce the similar injection indices in two episodes (i) the jet power in different episodes have to be similar and (ii) the Lorentz factor of the spine of the jet should be > 10. We further argue from particle acceleration physics that (iii) the jet fluid is made of electron-positron plasma and (iv) the inner jets of double-double radio galaxies are capable of forming hotspots even when propagating through the tenuous, nonthermal electron-positron plasma of the outer cocoon without any thermal matter in it. The episodic nature of the FR\,II radio galaxies we have studied appears to be unrelated to AGN feedback on the ambient medium.


Expected flux levels for nucleosynthetic gamma-ray line and continuum emissions from SN 1987A are calculated for several models. The dominant line emission is from freshly synthesized Ni-56 and its decay daughters, and the continuum is from Compton scattering of line photons. For a 15 solar mass Type II model, the light curve for the 0.847 MeV gamma-ray line peaks in September 1988 at 3 x 10 to the -4th photons/sq cm/s. This is detectable only by new, ultrasensitive balloon-borne spectrometers. For models with substantial mass loss from their envelopes, the peak is in early 1988 at about 0.01 photons/sq cm/s, which is detectable at high significance levels by all current instruments. The continuum emission in the 0.05-0.5 MeV band peaks about 100 days before the 0.847 MeV line peak. This Compton precursor is observable at about the same significance level as the lines.


The properties of path integrals associated with the allowance for nonstandard terms reflecting the operator nature of the canonical variables are considered. Rules for treating such terms (''equivalence rules'') are formulated. Problems with a boundary, the behavior of path integrals under canonical transformations, and the problem of quantization of dynamical systems with constraints are considered in the framework of the method.


All systems of (n+1)-dimensional quasilinear second-order evolution equations invariant under chain of algebras AG(1.n) contained in/implied by AG1(1.n) contained in/implied by AG2(1.n) are described. The results obtained are illustrated by the examples of the nonlinear Schrodinger equations, Hamilton-Jacobi-type systems and reaction-diffusion equations.

Modelling system security is not common practise in software projects yet. Among other problems, there is not a widely accepted methodology which unifies the actual heterogeneity of security issues when addressing a whole security specification. Certainly, the reality is even worse since there is not an accepted or standard common notation for carrying out the security specification. In this work, we study how modelling security issues, specifically resilience, could be integrated in the MARTE-DAM framework, which allows the expression of performance and dependability requirements in UML models. We base this claim on the close relationship between security and dependability. Indeed, MARTE proposes a framework for non-functional properties specification (NFP), while DAM exploits it for dependability purposes. So, our goal is to take advantage of the common NFP framework while the dependability and security concerns are modelled in a unified view. On the other hand, we consider that the resulting security specification will be useful for developing model in which security related properties, such as availability, will be analysed. We will clarify these claims by means of an example.


This paper presents performance improvements of a double excitation synchronous motor by using a reluctance network (RN). The distinguishing feature of the double excitation principle is to use permanent magnets with high energy, while air-gap flux is flexibly controlled by field windings. Therefore, the first contribution of this paper focuses on maximizing air-gap flux range control. Second, an approach for torque ripple reduction is proposed by directly modifying air-gap flux according to the instantaneous torque profile. The achieved resultant torque stays almost constant for a case study. The validity of the RN method is examined by comparisons with 3-D finite element and experimental results for several machines.


We consider the problem e 2 �v − v − γ1V v + f (v) = 0 � V + γ2|v| 2 = 0 ,v = V = 0o n∂�, where � ⊂ R 3 is a smooth and bounded domain, e, γ1 ,γ 2 > 0 ,v ,V : � → R, f : R → R.W eprove that this system has a least-energy solution ve which develops, as e → 0 + ,a single spike layer located near the boundary, in striking contrast with the result in (37) for the single Schr¨ odinger equation. Moreover the unique peak approaches the most curved part of ∂� , i.e., where the boundary mean curvature assumes its maximum. Thus this elliptic system, even though it is a Dirichlet problem, acts more like a Neumann problem for the single-equation case. The technique employed is based on the so-called energy method, which consists in the derivation of an asymptotic expansion for the energy of the solu- tions in powers of e up to sixth order; from the analysis of the main terms of the energy expansion we derive the location of the peak in � .

There have been a number of publications on spar Vortex-Induced-Motions (VIM) model testing procedures and results over the past few years. All tests allowing full 6 DOF response to date have been done under sub-critical Reynolds Number conditions. Tests under super-Critical Reynolds Number conditions have only been done with a fully submerged 1 DOF rig. Early in 2006, Chevron Energy Technology Company (CETC) completed a series of model tests to investigate the effect of Reynolds Number and hull appurtenances on spar vortex induced motions (VIM) for a vertically moored 6DOF truss spar hull model with strakes. Tests were done at both sub- and super-critical Reynolds Numbers, with matching Froude Numbers. In order to assess the importance of appurtenances (chains, pipes and anodes) and current heading on strake effectiveness, tests were done with several sets of appurtenances, and at various headings and reduced velocities. This paper addresses the challenges of performing spar VIM model tests at Super Critical Reynolds Numbers, and how they were resolved without the restrictions noted in earlier publications. Certain aspects of the effect of appurtenances and current heading on strake effectiveness and VIM response are discussed.Copyright © 2007 by ASME


As a result of the experimental work carried out in the Birmingham electric power station, it has been demonstrated that the use of pulverized fuel gives a higher combustion heat efficiency in the boilers than is obtained with mechanical stokers. Boilers having a capacity far greater than those equipped in the past with mechanical stokers can be used, with a consequent reduction in the capital cost of boilers and boiler house; this is a set-off against the higher capital cost of the pulverized-fuel equipment compared with mechanical stokers. The evolution of pulverized-fuel installations is tending towards reduced equipment and greater simplicity in operation; this is effected by eliminating the coal driers and the conveying and storage of the pulverized fuel.


We have investigated the electronic properties of ${\mathrm{BiS}}_{2}$-based superconductors by using x-ray photoemission spectroscopy (XPS). In going from $x=0.3$ to 0.5 in ${\mathrm{PrO}}_{1\ensuremath{-}x}{\mathrm{F}}_{x}{\mathrm{BiS}}_{2}$, the Pr $3d$ and Pr $4d$ peaks are shifted by $\ensuremath{\sim}0.10\ifmmode\pm\else\textpm\fi{}0.05$ eV from the Fermi level, partially consistent with the electron doping. In ${\mathrm{PrO}}_{1\ensuremath{-}x}{\mathrm{F}}_{x}{\mathrm{BiS}}_{2}$, the ${\mathrm{Pr}}^{3+}\ensuremath{-}{\mathrm{Pr}}^{4+}$ mixed valence remains unchanged with the electron doping from $x=0.3$ to 0.5. In ${\mathrm{CeO}}_{1\ensuremath{-}x}{\mathrm{F}}_{x}{\mathrm{BiS}}_{2}$, the doped electrons for $x=0.5$ almost suppress the ${\mathrm{Ce}}^{3+}\ensuremath{-}{\mathrm{Ce}}^{4+}$ valence fluctuation. Although the core-level peaks are also shifted by $\ensuremath{\sim}0.10\ifmmode\pm\else\textpm\fi{}0.05$ eV towards the higher-binding-energy side with the electron doping from $x=0$ to 0.5 in ${\mathrm{CeO}}_{1\ensuremath{-}x}{\mathrm{F}}_{x}{\mathrm{BiS}}_{2}$, the Bi $4{f}_{7/2}$ binding-energy shift is higher in the Pr system compared with the Ce system. The present results suggest that the doped electrons increase orbital occupations in the rare-earth $4f$ orbitals at the valence band and show valence fluctuations differently in the two systems.


Analysis related to the onset and evolution of the electron two-stream instability (ETSI) near a surface with a continuous photoemission flux is presented. With the help of a particle-in-cell simulation code, it is shown that when a surface emits photoelectrons due to exposure to ultraviolet photons (or due to similar mechanisms), it may lead to the onset of the ETSI due to the relative bulk velocity difference between the photoelectrons and the plasma electrons. It is shown that the ETSI thus developed is sustained through the lifetime of the plasma and prevents thermalization of the electrons, which leads to a distortion in the electron velocity distribution function (EVDF) resulting a high energy tail, at least near the surface. We have shown that the resultant EVDF can be highly Lorentzian with a spectral index of ∼1.5. The simulation results are supported with the corresponding theory, which are found to be in good agreement.Analysis related to the onset and evolution of the electron two-stream instability (ETSI) near a surface with a continuous photoemission flux is presented.

AbstractThe powder compactibility factors of a drug, an experiment and several drug-experiment combinations were detemined by plottlng the logarithm of the change in the powder bed volume contained in cylindrical containers versus logarithm of the applied pressure. The powder compactibility factor increased as the powder bulk density decreased and the plots of these two properties were linear at lower powder bulk densities. The plots of the logarithm of flow rate and the coefficient of variation versus the compactibility factor were also linear Indicating the usefulness of this method in predicting flow properties of powders and powder mixtures.


The method of producing a cathode active material, a lithium battery, the positive electrode active material and employing the same are disclosed. The positive electrode active material for a lithium transition comprises a metal oxide, and the differential voltage (V, horizontal axis) and the charge-discharge capacity of the positive electrode applying the lithium transition metal oxide in the negative electrode to the voltage value (dQ / dV, and the vertical axis) If shown, the non-reversible peak appears in the range 4.5V to 4.8V in the first charge-reversal cycle. The positive electrode active material can improve the initial efficiency and the discharge capacity of the lithium battery.

ABSTRACT Within the considerable body of research that the notion of parasocial interaction (PSI) has generated since the late 1950s, one aspect has been largely overlooked: the maintenance of one-sided relationships between fans and celebrities after the death of the latter. The present study focuses on this particular form of PSI, as reflected by memorial pages on Facebook dedicated to deceased public figures. Through a combination of content and theme analyses, we explored expressions of intimacy, role modelling, and identification by visitors of these pages and the subjects for whom these virtual shrines are designed. Corroborating findings from previous studies, our data revealed that a large number of postings serve a pseudo-dialogical function, allowing visitors to engage in public, unilateral 'conversations' with dead celebrities. Moreover, our analyses identified three recurrent themes underlying these pages: expansion of fans' communicating capabilities across different dimensions of reality; legitimisation of a traditionally disenfranchised form of social engagement through grief; and tacit expansion of the economies of attention that sustain the culture of celebrities. These themes have important implications for future explorations of PSI in connection with broader institutional and social factors.


The design problem of location algorithm in wireless sensor networks is investigated,and a new node positioning algorithm is proposed based on the mobile beacon node method.The main idea of the proposed algorithm is to use the mobile beacon node to traverse the entire network and to broadcast periodically the packet containing its current location information.The unknown node can calculate its location by the trilateration as long as it has received three or more such location information packets which have distances of one communication radius from the unknown node.Furthermore,in the case that there exists uncertainty in the communication radius,the maximum likehood estimation algorithm is adopted instead of the trilateration to improve the anti-noise property of the proposed node positioning algorithm.Simulations are carried out to study the characteristics of the algorithm,and they are compared with the DVHop node positioning algorithm.The simulation results demonstrate that the proposed location algorithm performs well on the aspects of location error,communication traffic and adaptability of the network architecture.


This study aimed at investigating outsourcing performance in Uganda's commercial banks basing on the variables of contract, relational norms, trust and commitment. It was motivated by the fact that where as outsourcing has been identified as a global trend in this millennium and a competitive strategy for the contemporary business, there were limited (if any) empirical studies on outsourcing performance in Uganda. Besides, previous studies conducted outside Uganda have provided conflicting views on whether or not contract and relational norms can be used concurrently to enhance outsourcing performance. The study was also intended to contribute to this debate by establishing the extent to which the variation in outsourcing performance was explained by the model that was developed. Findings revealed that the only significant predictor of outsourcing performance was contract and the model accounted for 40.1% of the variation in outsourcing performance. The findings present implications for commercial bank management in the area of contracting and contract management, which have to be addressed if outsourcing performance is to be enhanced and competitiveness in the banking sector improved.


Several fluorine containing arylfurylpropenones 3 have been synthesized starting from arylfurfurals 1 and 2,4-dich loro-5fluoroacetophenone 2. These arylfurylpropenones are then used for the synthesis of fluorine containing arylfurylpyrazolmes 4. The newly synthesized pyrazolines are then converted into their N-acetyl derivatives 5. The structures of these compounds have been confirmed on the basis of elemental analysis, IR, NMR and mass spectral studies. The mechanism for the fonnatlon of pyrazolines has been investigated. The above compounds are also subjected to antibacteri al screening. !heir minimal inhibitory concentration (M IC) valu es indicate that some of these compounds exhibit excell ent antibacterial activiti es. The chemistry of chalcones and their heterocyclic analogues has been an interesting field of study for long time. The chalcones are used as building blocks for many heterocyclic ringsl. Chalcones are found to inhibit the growth of several pathogenic micro organisms and fungi, whereas some of the chalcones are reported to possess important therapeutic properties such as hypertensive, anti peptic-ulcer activity etc. Heterocyclic analogues of chalcones are reported to possess bactericidal, bacteriostatic, cholerostatic activities 2 -4.


Long term laboratory experiments have been set up to measure the time dependant performance of multi-nailed connections. Deformatio ns are recorded from dial gauges and strain-gauge based deformation gauges previously us ed in short term applications. These devices are cost effective but long term drift and creep may need compensation. A 3 storey building in New Zealand has frames an d e ergy dissipating rocking shear walls constructed from laminated veneer lumber (LVL). Wal l post tension, wall shortening, deformation of the energy dissipating devices, floo r dynamics, moment rotations and mid span deformations are remotely monitored. Prelimina ry dynamic performance has been tested and verified the operation of the installed accelerometers and allowed the initial dynamic modes to be identified.


The knowledge of the floristic composition of the urban tree community helps the formulation of public policies and management decision-making. In this study, we sought to identify the species that comprise the afforestation of Diamantina, MG. Initially, we conducted a selective sampling of the urban area, recording the trees present on sidewalks, central flowerbeds and squares. Then, we calculate the Shannon index to assess the level of floristic diversity. The Shannon index was equal to 3.7, showing high floristic diversity. Most species are of native origin (64.03%) and most (77.83%) are located in the squares. We concluded that afforestation has good floristic diversity and a high frequency of native species, points recommended for urban afforestation. Squares are strategic spaces and should be the focus of public policies. It is recommended to draw up a afforestation plan, which guides and regulates the planting of trees.

Three industrial metallurgical cokes were examined using X-ray diffraction (XRD) and scanning electron microscopy combined with energy dispersive X-ray analysis (SEM/EDS). The study highlighted the difficulties and implications of identifying the inherent crystalline mineral phases in cokes using XRD such that increasing the ashing temperature led to the formation of anhydrite and destruction of metallic iron: microwave plasma ashing resulted in minimal alteration of the original coke mineralogy apart from the formation of bassanite and possibly jarosite. A preliminary scheme to characterize coke minerals is presented such that, physically, minerals can be classified as fine ({lt}50 {mu}m), coarse (50-100 {mu}m), and agglomerate ({gt}1000 {mu}m); chemically, minerals can be grouped as refractory, semirefractory, and reactive, while on the basis of distribution they can be described as discrete, disseminated, or pore inclusions. Quartz, cristobalite, mullite, and high melting point Al-silicates were found to be the predominant refractory phases while low melting point Al-silicates, e.g., containing high fluxing elements such as K, and Fe were the main semirefractory phases present in all cokes. A variety of iron containing phases including pyrrhotite, troilite, iron oxides, metallic iron, and iron silicates were also invariably present in all cokes while calcium phases were found to occurmore » as sulfide, silicates, and phosphates. In general, iron and calcium phases can be categorized as reactive phases with few exceptions such as oldhamite (CaS). The study highlighted that most of the cokes possess a similar mineralogy, with the main distinction being in their relative abundance, particle size, and nature of distribution in the coke matrix. The study provides a basis to develop a mechanistic understanding of the influence of minerals on coke reactivity and strength at high temperatures. 41 refs., 13 figs., 4 tabs.« less

Background: Hypofractionated radiotherapy in early breast cancer yields equivalent or better outcome in terms of efficacy, toxicity, cosmesis and cost-effectiveness. However, its role in node-positive breast cancer is less clear.
Aim: To compare between adjuvant conventional and hypofractionated radiotherapy in node-positive breast cancer.
Methods: Prospective pilot study of 66 node-positive breast cancer patients recruited over 1 year in a single institution. Patients were randomized to receive adjuvant conventional radiotherapy 200 cGy x 25 fractions with 200 cGy x 5 fractions boost to the tumor bed in case of breast conservation (control arm) or hypofractionated radiotherapy 266 cGy x 16 fractions with 266 cGy x 4 fractions boost to the tumor bed in case of breast conservation (intervention arm). The end points were disease-free survival, cosmetic outcome, ipsilateral arm lymphedema and acute skin reactions.
Results: Disease-free survival did not differ significantly between the two treatment arms (p = 0.6) and the 2-year disease-free survival rate was 87% and 89% in the hypofractionated and conventional arms. The rate of excellent/good cosmetic score was higher in the hypofractionated arm than the conventional as rated by patients (71% vs. 46%, p = 0.182) and physicians (29% vs. 8%, p = 0.32). Hypofractionation, when compared to conventional fractionation, was associated with less arm lymphedema (22% vs. 40%, p = 0.149), dry desquamation (28% vs. 53%, p = 0.04), skin darkness (0% vs. 15%, p = 0.054) and wet desquamation (16% vs. 21%, p = 0.601).
Conclusion: Hypofractionated adjuvant radiotherapy in node-positive breast cancer patients is equivalent to conventional fractionation as regards disease-free survival, cosmetic outcome and arm lymphedema with less early skin reactions.


Objective: To investigate the relationship between the cell number of day 3 embryo transferred and the clinical pregnancy rate in IVF-ET cycle,and how to select the best embryos on day 3 of culture for embryo transfer.Methods: This study involved 788 patients and a total of 792 IVF and ICSI cycles from January 2004 to June 2006.The embryos transferred on day 3 of culture were divided into four groups based on the cell numbers: group a,the cell numbers of embryo transferred ≤4;group b,the cell numbers of embryo transferred was 5~6;group c,the cell numbers of embryo transferred was 7~9;group d,the cell numbers of embryo transferred ≥10.Pregnancy was confirmed by ultrasound 4 weeks after embryo transferred.The implantation rate in each group was calculated by taking count of the numbers of fetus heart and the difference among groups was analyzed.Results: Embryos in group c resulted in the highest implantation rate(34.0%),higher than those in other 3 groups(P0.05).The embryos with 8 cells resulted in the highest implantation rate(34.8%),followed by the embryos with 9,7,10 cells(34.3%,31.6%,14.3%,respectively),while the implantation rates of the embryos with 5~6 cells were poor(8.70%).In those cycles which implantation rate of embryos transferred was 0 or 100%,the implantation rate of embryos with cell numbers≤4 or ≥11 at day 3 was 0. Conclusions: The pregnancy rate is closely related to the cell number of embryo transferred.When embryos were transferred on day 3 of culture,the highest pregnancy rate was found in the embryos with 7~9 cells.The embryo with 8 cells at day 3 should be the first choice for embryo transfer and the embryo with 9 or 7 cells ranks second,followed by the embryo with 10 cells,the embryos with 5-6 cells.The embryos with ≤4 or ≥11 cells are not eligible for fresh transfer cycle.

It is a very great pleasure to present the Mineralogical Society-Schlumberger medal to Paul Ribbe. Paul is a leading member, a Godfather even, of the feldspar Mafia, the group who have met once a decade since 1962, through the medium of the NATO Advanced Study Institutes programme, to review the state of knowledge and exchange the latest ideas on the most abundant, and in many ways the most complex, minerals of the Earths crust. Paul is one of three mineralogists (the others are Bill Brown and Joe Smith) who have been present at all four of these influential meetings. I'm a new-boy, with only three behind me, and I first met Paul at the July 1972


Under long spread condition, using 3 time-distance curve equations (Routine-hyperbolic curve time-distance equation, and two non-hyperbolic curve time-distance equations which containing high order and anisotropic parameters) to describe the characteristics and accuracies of seismic wave propagation were studied in this paper. The study results show that under long spread condition the high order and anisotropic non-hyperbolic curve velocity analysis method could get accurate stacking velocity and interval velocity, as a result better NMO and stacking results can be achieved. But when the spread is too long, accurate stacking velocity could not be obtained with high order non-hyperbolic curve method, and the anisotropic non-hyperbolic curve has a wider application scope.


Knowledge Visualization using graphical structure is a field in which the researchers have a strong influence on comprehensibility. Based on the information provided by the users, the knowledge is created. By mapping the logic generated based on the knowledge, we have created a new graphical structure using Cypher Query Language that shows the connectivity between each concept and their relationship. These knowledge visualization techniques are mainly suitable in finding the outcome of a situation and also in discovering new knowledge from the existing or by adding new information. An automated code is generated to build the graph structure for visualization in Neo4j. The reduction in content size and graphical structure helps the user to easily gain knowledge about the system.

Critical chain project management (CCPM) has been introduced in 1997 by Goldratt which was known for its theory, theory of constraint. Since then CCPM attracted a great attention both in academic world and execution communities. One of the most controversial points of the CCPM which is a subject of critics is the way it suggests for activity duration estimation. This paper proposes a new method for duration estimation of activities by measuring the amount of uncertainty embedded in each activity duration and then taking out of safety times associated with this uncertainty. The validity of the proposed method is tested by conducting a computer simulation on some test problems. Simulation analysis shows that the proposed method yields schedules which are more reliable than the schedules produced by original CCPM method of duration estimation.


This article analyses Lithuanian diminutives, which are very common in contemporary Lithuanian literature, and linguistic and socio-cultural strategies of translation of diminutives into French language. Diminutives are considered a linguistic peculiarity, which has stylistic and socio-cultural value in the text. Diminutives do not represent the translation unit but they are an intratextual component of the translation object. The analysis of 18 Lithuanian novels and their translations into French published between 2000 and 2012 shows certain tendencies of translation of diminutives. The analysis of grammatical, semantic and pragmatic translation strategies of Lithuanian diminutives reveals how French translators express cultural peculiarities of Lithuanian literature and pass from one cultural system to another


Over the last few years, the deployment of wireless sensor networks (WSNs) has been fostered in diverse applications. WSN has great potential for a variety of domains ranging from scientific experiments to commercial applications. Due to the deployment of WSNs in dynamic and unpredictable environments, these applications must have potential to cope with variety of faults. This paper proposes an energy-aware fault-tolerant clustering protocol for target tracking applications termed as the Fault-Tolerant Target Tracking (FTTT) protocol. The identification of redundant nodes (RNs) makes sensor node (SN) fault tolerance plausible and the clustering endorsed recovery of sensors supervised by a faulty cluster head (CH). The FTTT protocol intends two steps of reducing energy consumption: first, by identifying RNs in the network; secondly, by restricting the numbers of SNs sending data to the CH. Simulations validate the scalability and low power consumption of the FTTT protocol in comparison with LEACH protocol.


At 19—20 h of age, the Ciona intestinalis ascidian tadpole has six developed organ systems (tunic, epidermis, notochord, tail musculature, adhesive organ, and nervous system) and approximately four organ system rudiments (including: pn mordial pharynx, atrial primordia, gut primordium, and mesodermal pockets). Con temporarylight and electron microscopic descriptions of the anatomy and the his tology of these tissues support the old contention, originated by Kowalevsky in 1866, that the body plans of tunicate tadpole and of vertebrate larvae are homologues.


Objective:To detect the expression of RANTES and CCR3 in the tissue of OLP and normal oral mucosa and to explore the role of RANTES and CCR3 in the process of OLP. Method:Specimens were collected from 30 patients with OLP and 10 normal oral mucosa. The expressions of RANTES and CCR3 were measured by streptavidin-peroxidase(SP) technique. Result:The expression of RANTES and CCR3 in OLP is significantly higher than that of the normal oral mucosa. Conclusion:Compared with the tissue of normal oral mucosa,the different expression and distribution of RANTES and CCR3 in OLP suggest that RANTES and CCR3 probably play an important role in the process of OLP advancement.


This research study explored the lived experiences of adults diagnosed with Coronary Artery Disease (CAD) when exposed to a prolonged period of extreme cold.


In this work, we have investigated the adsorption behavior of the CN radicals on electronic properties of BC2N nanotube (BC2NNT) by means of the B3LYP hybrid density functional method using 6-31G(d) basis set. The results show that CN radicals can be chemically adsorbed on the nanotube. Based on the energy analysis, the most stable position of CN radical on the nanotube is C1 site. Also, the C-side complexes are more stable than the N-side complexes. We investigated the effects of CN radicals adsorption on the electronic properties of the BC2N nanotube. According to our calculations, band gap energy of the BC2NNT decreases with increasing the number of CN radicals. It is predicted that the conductivity and reactivity of nanotube increase by increasing the number of CN radicals. Based on the NBO analysis, in all complexes charge transfer occurs from nanotube to CN radical. The AIM results show that, the Xtube…YCN interaction has covalent nature. Generally, The BC2N nanotube can be used to as sensor for nanodevice applications.


With the widespread use of Internet of Things (IoT) in every aspect of human's daily life, communications of such an enormous amount of existing embedded devices in these systems arise many new challenges from power consumption, performance, and reliability perspectives. Communications in an IoT infrastructure are managed by a set of policies which are determined by Objective Functions (OFs). Thus, OFs are the most important contributors in facing with the mentioned challenges. In this paper, due to the lack of information on how OFs affect the primary properties of an IoT infrastructure, we have compared three well-known OFs (OF0, MRHOF, and OFFL) from power consumption, performance, and reliability perspectives. This paper would pave the way for scholars to realize which of the three mentioned areas are more affected by OFs. Our evaluation results on Contiki's IoT simulation environment (COOJA) illustrate, OFs could affect the power consumption by up to 71.2%, while their impacts on reliability and performance would be as high as 77.5% and 25.15%, respectively.
