The present article refers to the improvement of the procedure for filling the position of the Governor of a con-stituent entity of the Russian Federation, which occurred as a result of the adoption of the Federal Law No. 414-FZ of December 21, 2021 "On General Principles of Organization of Public Power in Constituent Entities of the Russian Federation". The impact of the reform of public power in the subjects of the Russian Federation on direct and indirect gubernatorial elections is assessed, the results of the legislation modification of the Russian Federation subjects on the organization of public power are analyzed, the forecast about further directions of the reform is given. In the author's opinion, the adoption of the new federal law has insignificantly affected the procedure for filling the position in question, which indicates the stability of the institution under study. Certain novels, objectively dictated by political expediency, legislatively formalize the actually established format of subordination relations between the President of the Russian Federation and the governors of the constituent entities of the Russian Federation.


To analyse the application of a new narrow‐band imaging (NBI) classification in the diagnosis of vocal cord leukoplakia by laryngologists with different levels of laryngoscopic experience and to explore the impact of NBI training programmes on laryngologists' identification of benign and malignant leukoplakia.


Introduction: Effects of many flavonoids have been studied on memory, learning and improvement of Alzheimer. Many flavonoids are effective in the improvement of Alzheimer. Since no study has been conducted on the effect of salvigenin on memory and learning, our aim was to examine the effect of this flavonoid. Methods: Intraperitoneal injection of D-galactose at a dose of 120 mg / kg was used for 45 for creation of Alzheimer disease model. In this experimental study, 28 male wistar rats weighing approximately 200-250 grams were divided into 4 groups with 7 members, including: normal group: rats that received no drugs, control group: alzheimer disease model rat, which had been stricken to Alzheimer by intraperitoneal injection of D-galactose at a dose of 120 mg/kg and 1, 2 salvigenin groups: in which each group was the same as the control group. Furthermore, they received daily 10 or 20 mg/kg of salvigenin by gavage. In order to evaluate memory, shuttle box and passive avoidance learning was used 2 and 7 days after learning. To assess the mRNA expression rate of BDNF, the entire RNA of hippocampus was isolated and after synthesis of Complementary DNA (cDNA), real time and PCR were done and relative expression of mRNA was evaluated. Results: The results showed that daily administration of different doses of salvigenin can slow down Alzheimer's induction. The delay duration in entering the dark compartment in trained rats in the treated group was significantly more than the control group. mRNA expression rate of BDNF in salvigenin receiving groups was more than control group. Conclusion: Generally it can be concluded that salvigenin can improve the memory caused by Alzheimer and also increase mRNA expression rate of BDNF in Alzheimer's rats.


Aim To determine whether there existed melatonin receptor (MR) in adult hepatoma tissue and to observe its property of binding.Methods Immuno-histochemistry was used to detect MR and identify its subcellular distribution. Specific binding and kinetic analyses of melatonin receptor were measured by radioligand binding assay.Results The results of immunohistochemistry showed that MT1 and MT2 existed in membrane,cytosol and nucleus of the hepatoma cells,but the expression of them principally localized in the membrane and cytosol. The specific binding assay properties of MR were presented as follows:the maximum binding capacity (Bmax) was (0.29±0.07) pmol·g-1 protein. Equilibrium dissociation constant (Kd) was (48.7±6.5) pmol·L-1. The trait of MR,saturation and reversibility,was detected by 125I-Mel specific binding kinetic analyses.Conclusions MR exists in adult hepatoma cells,furthermore,the subtypes of MR (MT1 and MT2) coexist in the membrane and cytosol,respectively,whose characters of the specific binding sites were low binding capacity,high affinity,saturation and reversibility.


A capacitively loaded planar inverted F antenna (PIFA) for a portable RFID application is presented. The antenna consists of four parts: a ground plane, a rectangular radiator with cut slots, an excited stub, and a shorting pin on the right-hand side that connects the ground plane to the rectangular radiator. The excited stub and the rectangular radiator are forms capacitive coupling. The capacitive coupling and shorting pin are used to effectively reduce the antenna size. Parametric studies of the proposed antenna are discussed to understand the operating mechanism and to produce a brief design guideline. The proposed antenna is easy to integrate in radio frequency devices for low manufacturing costs.


We conducted a spectroscopic survey of cometary volatiles with the Infrared Camera on board the Japanese infrared satellite AKARI in the wavelength range from 2.5 to 5 μm. In our survey, 18 comets, including both the Oort cloud comets and the Jupiter-family comets, were observed in the period from 2008 June to 2010 January, most of which were observed at least twice. The prominent emission bands in the observed spectra are the fundamental vibrational bands of water (H2O) at 2.7 μm and carbon dioxide (CO2) at 4.3 μm. The fundamental vibrational band of carbon monoxide (CO) around 4.7 μm and the broad emission feature, probably related to carbon–hydrogen-bearing molecules, can also be recognized around the 3.3–3.5-μm region in some of the comets. With respect to H2O, gas production rate ratios of CO2 have been derived in 17 comets, except for the comet 29P/Schwassmann-Wachmann 1. Our data set provides the largest homogeneous database of CO2/H2O production rate ratios in comets obtained so far. The CO2/H2O production rate ratios are considered to reflect the composition of cometary ice when a comet is observed at a heliocentric distance within ∼2.5 AU, since H2O ice fully sublimates there. The CO2/H2O ratio in cometary ice spans from several to ∼30% among the comets observed at <2.5 AU (13 out of the 17 comets). Alternatively, the ratio of CO/CO2 in the comets seems to be smaller than unity based on our observations, although we only obtain upper limits for CO in most of the comets.


Chemical compositions and microstructures of IrO2-Ta2O5 coated titanium electrodes were characterized by XRD, XPS and SEM, and their electrolysis behavior in sea water was studied using cyclic voltammetry. The effect of IrO2 content on the microstructure and service life of the IrO2-Ta2O5/Ti oxide electrode was discussed as well. It was found that the voltammetric charge and service life showed maximum values at a 70 mol% of Ir. In addition, auxiliary anodes complying with commercial dimensions for applications in the cathodic protection systems of condensers were fabricated with optimal parameters. The auxiliary anodes showed excellent performance during a one-year service test and have the potential to replace conventional platinum coated titanium electrodes.


Changes in renal arteries hemodynamics are earlier than those in renal function. The parameters of renal arteries hemodynamics by color Doppler ultrasonography can reflect the secondary renal infusion changes.


A simple, low cost and highly sensitive method based on cloud point extraction (CPE) used for separation/preconcentration of zinc and iron has been described. After complexation with new ligand, Dithizone (DZ) followed determination of these ions by flame atomic absorption spectrometry. The ions are quantitatively extracted to the phase rich in Triton X-114 following centrifugation. The parameters which affecting the separation phase and detection process, were optimized such as pH, DZ, Triton X-114. Calibration graph showed linear trend in rang of 0.2-2.0 μg 1 for both analyts. The analyst were determined in petrochemical waste water sample which gave satisfactory results.


A compact broadband 220 to 400 MHz lumped element RF circulator has been developed using novel band-switchable, single-tuned matching networks at each port. Isolations of greater than 15 dB and mid-band insertion losses of 1dB were obtained.


In this research, we examine the empirical relation between client characteristics and the nature and mix of labor resources used by an international CPA firm to obtain a desired level of assurance that clients' financial statements are free of material misstatement. The level of assurance is the output of an audit, while the input resources measure the effort required to produce that output, under varying client circumstances. We use disaggregated labor hours by rank within the firm (partner, manager, senior, and staff) as the measure of inputs, in order to examine how client characteristics affect both the amount and mix of labor used. To the extent that client characteristics have differential effects on the various types of labor, only disaggregated data can reveal changes in labor mix and may also provide a more powerful test (relative to tests


The articles in this Special Issue are concerned with the interaction between cities and ethnicities.1 Cities have become sites of intense ethnic mixing, although the exact nature and extent of that mixing obviously differ from city to city in significant ways, leading to highly differentiated levels of integration, senses of belonging and quality of life experience.2 Cities matter in the daily negotiations of 'race', ethnicity and cultural difference yet the significance of place and the everyday has tended to remain secondary in an otherwise rich literature on ethnic identities, race and multiculturalism. Much of the discussion on belonging, for example, has tended to focus on the clash or resonance between (global) diasporic affiliations and national models of belonging, with less emphasis placed on local modes of belonging shaped by, say, community cultures and senses of place, and opportunities for autonomy and cultural mingling in the public sphere at the local level. Similarly, discourses on racism and multicultural dynamics (with the exception of some excellent work on local anthropologies of ethnicity) have tended to focus on the role of national articulations of political philosophy (liberal, communitarian, and so on), minority rights, immigration and race legislation, institutional conduct, and general attitudes and practices towards 'outsiders'. An unwitting consequence has been to underestimate the significance of local microcultures of inclusion and exclusion, influenced by such factors as local class relations and G U E S T E D I T O R I A L


Two kinds of problems for unsteady fluid flow with leaky linear boundaries in one dimensional media are investigated. The linear boundary with leaky conditions is formulated first. On the basis of the boundary condition, two kinds of problems about transient flow with points source in one dimensional porous media are evaluated analytically by using integral transformation. Two types of novel point source functions, which can be direct employed in construct of solutions for well test analysis, are presented. Both expressive characteristics and concrete applications of the functions are illustrated with improved solutions for well test analysis in two dimensional rectangle reservoirs. It is expressed that the penetration coefficient can denote the penetrating ability of leaky boundaries while traditional boundaries either no flow or constant pressure are limited patterns of the leaky linear condition. It is shown that a pressure diagnosis curve for a fixed penetration coefficient is situated between a no flow boundary and a constant pressure boundary.


The most common symptoms of chronic beriberi due to thiamine deficiency include dyspnoea, fatigue, leg oedema, lower extremity weakness and numbness. When collapsed peripheral circulation, metabolic acidosis, or shock are present, the disease has advanced from chronic beriberi to pernicious or fulminating beriberi heart failure (Shoshin beriberi). We report two patients with fulminating beriberi; Accepted both of whom had been incarcerated at a detention centre for 5 months before hospitalization. A prolonged monotonous diet, low in thiamine, was a major risk factor in both patients. Thiamine deficiency should be considered for any patient with symptoms and signs compatible with beriberi.


* a Condensed phase access to the unprecedented tetrahedral cations [EP 3 ] + (E ¼ S, Se, Te) was achieved through the reaction of ECl 3 [WCA] with white phosphorus ([WCA] (cid:2) ¼ [Al(OR F ) 4 ] (cid:2) and [F(Al(OR F ) 3 ) 2 ] (cid:2) ; – R F ¼ – C(CF 3 ) 3 ). Previously, [EP 3 ] + was only known from gas phase MS investigations. By contrast, the reaction of ECl 3 [A] with the known P 3 3 (cid:2) synthon Na[Nb(ODipp) 3 (P 3 )] (enabling AsP 3 synthesis), led to formation of P 4 . The cations [EP 3 ] + were characterized by multinuclear NMR spectroscopy in combination with high-level quantum chemical calculations. Their bonding situation is described with several approaches including Atoms in Molecules and Natural Bond Orbital analysis. The fi rst series of well-soluble salts ECl 3 [WCA] was synthesized and fully characterized as starting materials for the studies on this elusive class of [EP 3 ] + cations. Yet, with high [ECl 3 ] + fl uoride ion a ffi nity values between 775 (S), 803 (Se) and 844 (Te) kJ mol (cid:2) 1 , well exceeding typical phosphenium ions, these well-soluble ECl 3 [WCA] salts could be relevant in view of the renewed interest in strong (also cationic) Lewis acids.


Gas doping method is an important auxiliary method of Float-Zone silicon single crystal due to its simple,flexible,short production cycle,lower costs and so on.Based on the principle of the gas doping technique,theoretical calculation of relations between resistivity and doping quantity is investigated considering diameter and growth rate of single silicon crystal,gas flowing and concentration,impurity segregation and absorption of doping gas by the crystal.A formula is gained which can more precisely control the resistivity of the crystal and decrease the error between theoretical calculation and the actual resistivity from 20% to 10% and thus,reduce the commercial cost of the doping process.


Solid oxide fuel cells are recognized as a promising energy conversion technology. Crucial to the field is the opportunity to reduce the costs of prototyping methodology. Due to the difficulty of conducting direct measurements inside the electrodes and fuel cell's channels, numerical modeling remains the primary tool for improving the understanding and analyzing a fuel cell operation. Here, a computational fluid dynamic simulation of a banded solid oxide fuel cell's stack, applied to enhance the geometrical design, is shown. A mathematical model, which includes momentum, heat, mass, and charge transport phenomena, was developed and used for the numerical simulation. The model was validated against the experimental study and confirmed its accuracy. The gas flow rate influence on the performance was investigated in details. Various arrangements of fuel and air channels were simulated and analyzed, including extending the system into a short stack. The proposed design modifications led to an increase in the volumetric power density of the stack compared to the existing prototype design. The proposed mathematical and numerical models were shown to be useful for testing further design modifications to the stack, including performance analysis, by changing the operating parameters of the system or applying new materials.


One way to detect and assess software vulnerabilities is by extracting security-related information from commit messages. Automating the detection and assessment of vulnerabilities upon security commit messages is still challenging due to the lack of structured and clear messages. We created a convention, called SECOM, for security commit messages that structure and include bits of security-related information that are essential for detecting and assessing vulnerabilities for both humans and tools. The full convention and details are available here: https://tqrg.github.io/secom/.


Traffic engineering products have two major functions: to guild and indicate signals, they can directly affect drivers vision and mind, its chromaticity characteristics are important parameters index, also those products are the significant parts of active safety. The current traffic engineering products chromaticity test depends on people to trace points in the printed paper to judge whether the parameter is qualified or not. According to the defects, the author developed a set of chromaticity test softwares about traffic engineering products, aiming to improve measurement accuracy and test efficiency. And these softwares have already successfully been operating in the test of traffic engineering products.


Huntington's disease (HD) is a devastating neurodegenerative disorder that is characterized clinically by movement, cognitive, and psychiatric disorders. After illness onset, disability is relentlessly progressive, and the outcome is uniformly fatal. HD is caused by an abnormal CAG triplet repeat expansion in the coding portion (exon 1) of the gene for a protein called huntingtin.1 How the mutation kills neurons is not clear and, as a consequence, there is not yet a way to prevent, slow, or stop the progression of degeneration.

HD runs in families; those at risk and those who are affected know what HD has done to other family members, and they are desperate for a cure. Clinicians who care for HD families often feel powerless and inadequate: temporary symptomatic treatment and palliative support just aren't enough. We need something better, and we need it now. People with HD are getting worse and dying.

What about replacing the neurons that die in HD? Assuming we know which cells to replace, this is a logical approach. The striatum bears the brunt of the pathology in HD, so this might be a good choice. Conversely, the average brain of someone who has died with HD weighs about 300 grams less than normal, and striatal atrophy can only account for a small fraction of this (∼50 grams). So, although HD pathology is …


This essay will explore's the mirroring of erotic desire and violence that Dennis Cooper undertakes in his poetry anthology The Dream Police (Selected Poems 1969-1993). Drawing mainly on Jacques Lacan and Georges Bataille, it will be argued that sexual violence is the vehicle which Cooper uses to liberate eroticism from what in psychoanalysis is known as the Symbolic —the order of the human mind ruled by sociocultural prescriptions. This liberation is productive of alternative knowledge about Cooperian subjects and their vicissitudes in desire, especially the poietic metaphorization of their sexual drives. On articulating this view, this piece of research departs from the critical line that conceives Cooper's violent ars erotica as either an elicitor of nihilism or the annihilation of otherness.


Legislate evolution of peasant material rights are actually one of suffering thoughts about advancing with the times,non-forgetting crisis in prosperity,non-forgetting turmoil in government.Peasant problem is the center problem of Chinese revolution in the past,and is the center problem of Chinese socialism construction today and in the long future.On the first half of the 20th century,the chief task of protecting Chinese peasant rights is to push peasant material rights' legislation about having significance of ruling by law and containing justice value.And then peasant economic and social rights would be protected legally and effectively.The center value of policies to solving country social contradiction must begin from protecting effectively peasant rights.The most important thing is to improving peasant material rights about people's livelihood and civil rights,and then to solving peasant material problems by lawmaking after combining good policies.And at the same time,we should make positive laws according to the rule of natural justice,should find often new social rules on the base of developing social practice,and then we will promote good law and ruling of the society.


Abstract Social workers engaged in family treatment frequently encounter families in which religious fundamentalism serves as a major steady-state and boundary maintenance mechanism. Without recognition of the systemic effects of religious fundamentalism, family therapists will lose the family from treatment or will be rejected by the family as a source of help. This article identifies the major impact on the family, sets forth assessment guidelines, and presents training strategies for teaching family practitioners to work with the religiously fundamentalist family.


Abstract The mechanism of insulin biosynthesis and secretion is only partially understood, and new evidence suggests that its complexity is greater than previously thought. Thus, ultrastructural evidence indicates the presence of a discontinuous, microvesicular transfer of secretory material between rough endoplasmic reticulum and Golgi complex, and further suggests that more than one morphologic mode of insulin release must be considered. Similarly, biochemical evidence suggests that stimulation of insulin release involves a multicomponent system including cyclic 3′, 5′ AMP, α and β autonomous nervous receptors, Ca++ and at least two types of substrate effects, one of them specific for certain substrates only. The complexity of the stimulatory mechanism involved is particularly well illustrated by studies with metabolic inhibitors — for example, mannoheptulose inhibits glucose-induced stimulation of insulin release, as expected, but enhances insulin release induced by tolbutamide. D-2-deoxyglucose inhibi...


The presence of slavery in Plato's political and ethical thought is marked by two contrary tendencies: one signals the conventional character of statutory slavery and tends to reduce the moral boundary between free people and servile people; the other one, going in the opposite direction, strongly reaffirms the functional frontier between these two categories, and makes it impassable. What does this double gesture of integration and exclusion of slavery mean with respect to Plato's political thought? My claim, based on the analysis of a passage in Book vi of the Laws and some excerpts from the Statesman, is the following: for Plato, the statutory slavery fulfills the function of drawing the inner civic boundary on which the political field must be built if it is to have a true conceptual autonomy, by contrast with what contributes to its construction but without being fully political.


The results of investigations into 15 ambient polycyclic aromatic hydrocarbons at two Polish fire stations belonging to the National Fire Service are presented. At each station, on five different days, hydrocarbons were sampled simultaneously in the changing room, garage, and exterior of the station (in the atmospheric air). The indoor and outdoor diagnostic ratios and benzo(a)pyrene carcinogenicity equivalents were computed from the measured concentrations. The former indicated the combustion of various materials and fuels as the hydrocarbons source, the latter expressed the cumulative carcinogenic hazard from the hydrocarbon mixture. Naphthalene and acenaphthene had the greatest ambient concentrations at each site. The greatest summary concentrations of the 15 hydrocarbons occurred in the changing rooms.


Cu pattern-laminated fabric substrates using epoxy-based B-stage adhesive films were demonstrated. Fine-pitch Cu electrical patterns were fabricated on B-stage adhesive films and then laminated to fabrics. As a result, fabric substrates having minimum Cu line width of $80~\mu \text{m}$ were successfully fabricated without any Cu lines displacement and fabric damages. First, the effects of the curing properties of adhesive films on fine-pitch Cu patterning were investigated by Fourier transform infrared (FTIR) spectroscopy and a 90° peel adhesion test. In addition, the morphology of the Cu pattern-laminated fabric substrates was observed depending on the viscosity of epoxy laminating adhesive film. Finally, the effects of film moduli on the dynamic bending fatigue properties were investigated experimentally and theoretically.


Guinea worm disease (dracunculiasis)—now limited to sub-Saharan Africa—is caused by the nematode Dracunculus medinensis, whose life cycle involves aquatic copepod crustaceans. Humans are infected when they drink water containing infective larvae. Adult worms enter subcutaneous tissue and can reach a metre in length. Clinical presentation is usually with a skin blister, most often on the leg, sometimes preceded by allergic prodromal symptoms. Bacterial infection and local scarring with disability are common complications. Most patients in endemic areas recognize their condition, but irrigation of ulcers can reveal larvae. Treatment is by physical removal of the worm; anthelmintics have no role in management. Provision of safe water for drinking is the key to prevention. The disease is now nearing eradication.

This paper is designed for the site of hybrid energy power system of solar and diesel generator. Referring to the site survey information, we propose an optimized configuration method which includes solar photovoltaic panel capacity, battery capacity and diesel generator capacity for the hybrid power system. The optimized configuration method reduce the initial investment of the investors. After analysis of historical data of a large number of hybrid sites, we also propose an intelligent control strategy to achieve the goal of zero discarding solar energy to maximize the use of solar energy, and reduce the running time of diesel generator. And then the maintenance costs of the operator are reduced.

The compound trans-1,5-dichloro-9,10-diethynyl-9,10-dihydroanthracene-9,10-diol (DDDA) has an inversion center as the only molecular symmetry element and yet does not occupy an inversion center in the centrosymmetric space group that it adopts in the crystal structure. The reason for this very unusual occurrence is the crowded environment of the H-bond donors and acceptors that leads to less than optimal H-bonding. A centrosymmetric supramolecular synthon constituted with four Cl-atoms in a planar array occupies an i site in the crystal, and this appears to provide a satisfactory alternative packing. Based on the hypothesis that H-bonding is less than optimal in the crystal structure of DDDA, pseudopolymorphs were prepared with strongly H-bond-accepting solvents. The crystal structures of five of these solvates are described, wherein the DDDA molecule is able to occupy an i site and form strong and linear OH ⋅⋅⋅O H-bonds with the solvent molecules. Competition experiments show that a smaller solvent molecule with a greater H-bond-accepting ability is included more readily and that the H-bonds formed are correspondingly better.


With the continuous development of economic globalization and Internet technology, the substantial increase in the demand for cross-border E-commerce-related talents has made cross-border E-commerce teaching in colleges and universities a focus of common concern in the education and economic fields. However, the research results on cross-border E-commerce teaching in colleges and universities are still not very satisfactory. As the online classroom model is gradually recognized by teachers and students, the development of VR technology has brought new changes to the teaching model. This research aims at the current shortage of cross-border E-commerce talents, and combines VR technology and online classroom mode to put forward a new view on college cross-border E-commerce teaching. First of all, based on the flipped classroom model and VR technology, this paper constructs a complete VR online classroom system. After testing the system, it is put into the cross-border E-commerce course teaching for sophomores majoring in international economy and trade. The students were divided into experimental group (n = 19) and control group (n = 19). The experimental group adopted VR online classroom teaching, while the control group adopted ordinary online classroom teaching. After one semester of study, the two groups of students were given written test of professional basic knowledge and operation test of cross-border E-commerce simulation platform, and the scores of the two groups were compared. The teachers and students were interviewed and investigated by questionnaire. The results showed that the average score of the written test in the experimental group was 75.2, and that in the control group was 77.6; the number of students with a score in the experimental group was significantly higher than that in the control group; 79% of the students in the experimental group could maintain a high concentration, while only 53% in the control group. This shows that although the students in the experimental group have a lower mastery of the basic professional knowledge of cross-border E-commerce than the students of the control group, they are better than the students of the control group in the operation ability of the cross-border E-commerce simulation platform. VR online classroom teaching needs more preparation time, but it can better attract students' interest.


In one sense philosophers of the last sixty or so years have written a lot about games and sports, since they've used analogies with them to illuminate claims on many other philosophical topics. Perhaps best known is Ludwig Wittgenstein's use of "language-game" to refer to specific portions of our linguistic practice (1953) and the continued use of that term by later philosophers of language (e.g., ...


We report the numerical simulation results obtained using a two-frequency coherence function in the double-weighted Fourier transform approximation. We perform the simulation for different models of inhomogeneous media.


General game players can drastically reduce the cost of search if they are able to solve smaller subproblems individually and synthesise the resulting solutions. To provide a systematic solution to this (de-)composition problem, we start off with generalising the standard decomposition problem in planning by allowing the composition of individual solutions to be further constrained by domain-dependent requirements of the global planning problem. We solve this generalised problem based on a systematic analysis of composition operators for transition systems, and we demonstrate how this solution can be further generalised to general game playing.


A series of high-dose-rate (20-kGy/h) and low-dose-rate (<10-Gy/h) irradiations of a large sample of plastic scintillating fibers (1-mm phi , 150-cm length) has been completed. Measurements of the transmission characteristics of the fibers have been completed. The transmission measurements show striking features: (1) those fibers irradiated slowly in air (i.e. in the presence of oxygen) suffer the greatest level of damage, while (2) the fibers irradiated rapidly, and then allowed to recover, display the least amount of damage, and (3) fibers irradiated slowly in argon display a level of damage intermediate between the other two. One fiber, the green-emitting SCSF-Y8, is the only exception, and shows no difference in the level of damage observed in the three modes of irradiation.<<ETX>>

We deduce on hourly basis the spatial gradient of the cosmic ray density in three dimensions from the directional anisotropy of high-energy (~50 GeV) galactic cosmic ray (GCR) intensity observed with a global network of muon detectors on the Earth's surface. By analyzing the average features of the gradient in the corotational interaction regions (CIRs) recorded in successive two solar activity minimum periods, we find that the observed latitudinal gradient (Gz) changes its sign from negative to positive on the Earth's heliospheric current sheet (HCS) crossing from the northern to the southern hemisphere in A 0 epoch. This is in accordance with the drift prediction. We also find a negative enhancement in Gx after the HCS crossing in both A 0 epochs, but not in Gy. This asymmetrical feature of Gx and Gy indicates significant contributions from the parallel and perpendicular diffusions to the the gradient in CIRs in addition to the contribution from the drift effect.


When charities confront the issue of disaster relief, they do not need to operate like ships in uncharted waters. In fact, many of the issues they face are very similar to those confronted by the government in setting up tax and expenditure programs.


VOLTAGE SENSOR CHARGE LOSS ACCOUNTS FOR MOST CASES OF HYPOKALEMIC PERIODIC PARALYSIS To the Editor: Matthews et al.1 highlight the importance of mutations in the arginine residues in S4 voltage sensors of skeletal muscle Ca and Na channels in the genesis of hypokalemic periodic paralysis (HypoKPP) types 1 and 2. Previous studies have demonstrated that loss of charged arginine residues produces a leak current pathway through portions of the ion channel that support voltage-induced movements of the S4 segments.2 Current flowing through the alternative ion pathway created by the S4 mutations could account for the anomalous cation depolarizing current that occurs in type 2 HypoKPP and is likely present in type 1 HypoKPP. Current passage via an alternative pathway would also explain why the anomalous depolarizing current is not blocked by traditional Na or Ca channel blockers.3 The highly selective association of the arginine gating pore mutations with the HypoKPP phenotype suggests that this type of mutation is likely key to the genesis of this phenotype. The authors also consider whether other ion channel alterations associated with HypoKPP are important for creation of the phenotype.1 Type 1 HypoKPP is associated with reduction in the outward current component of the inward rectifier K channel (Kir).3 While reduced Kir may be an epiphenomena, a role for reduced Kir in the HypoKPP phenotype has been suggested. Reduced Kir is the ion channel defect responsible for Andersen syndrome, which includes a periodic paralysis phenotype. Increasing K current may be the mechanism of action of acetazolamide-induced improvement in HypoKPP symptoms.4 In type 2 HypoKPP, the Na channel mutations reduce the available Na current through enhanced channel inactivation.5 The density of Na may be reduced in type 1 HypoKPP.6 Lower Na current density is consistent with reduced action potential conduction velocity and could contribute to the HypoKPP phenotype by reducing membrane excitability thereby facilitating paralysis due to membrane inexcitability. These arguments suggest that reduced Kir and Na currents contribute to the HypoKPP phenotype, yet they do not prove that they are critical. The arginine mutations directly produce the anomalous depolarizing current. How do the mutations reduce other currents? Perhaps the mutations, by creating an alternative path for cations to enter, may indirectly contribute to the changes in Na and Kir channel function by altering the intracellular ionic composition.6

Abstract Blue supergiants (BSGs) to the right the main sequence band in the HR diagram can not be reproduced by standard stellar evolution calculations. We investigate whether a reduced convective core mass due to strong internal magnetic fields during the main sequence might be able to recover this population of stars. We perform calculations with a reduced mass of the hydrogen burning convective core of stars in the mass range 3–30 M⊙ in a parametric way, which indeed lead to BSGs. It is expected that these BSGs would still show large scale magnetic fields in the order of 10 G.

Background and Aim: Dry eye disease has a significant impact including physical, social, psychological, negatively affecting daily activities and workplace productivity. This study is conducted to find the prevalence of dry disease in patients of type 2 diabetes mellitus and to find the correlation between glycemic control and prevalence of dry eye. Material and Methods: A total of 130 patients fulfilled the criteria and total 200 eyes are included in the study. Type II diabetic patients diagnosed by the American Diabetes Associations criteria. The duration of diabetes, fasting and post-prandial blood sugar and Hb1Ac values were recorded. A complete ocular examination of the lid margins, conjunctiva, cornea and tear film was done. Examination of fundus was done to access the grade of diabetic retinopathy in the patients. Relevant examination of other important ocular structures was done. Following this, tests to diagnose dry eye were performed. These are tear break up time (TBUT), ocular surface staining by Rose Bengal and fluorescein staining, Schirmer's tests and conjunctival impression cytology. Diagnosis of dry eye was made if OSDI Score was more than 12 with one of the positive specific tests for dry eye. Results: Prevalence of dry eye in diabetes in males and females were comparable to each other that are 44.99% and 54.01%. A statistically significant co-relation was found on comparing between Schirmer score of that eye and HbA1c level of that individual. All the patient with severe NPDR and PDR had Schirmer score of below 5 mm. Our study found that with increased duration of diabetes, the chance of developing dry eye increases, and poor glycemic control increases the severity of dry eye. The severity of diabetes has a positive correlation with goblet cell loss and morphological changes in conjunctival impression cytology. Conclusion: Significant correlation between the prevalence of dry eye in the diabetic patient which shows poor glycemic control is directly related to dry eye. This study reveals that attention should also be paid on dry eye, particularly among patients suffering from DM when they are concerned about diabetic retinopathy.

E THNOMUSICOLOGY has traditionally been classified within the systematic branch of musicology rather than the historical, but historical interests and orientations have always played a considerable part in it; indeed, they have at times been the predominant motivating forces in investigation. However, the preference for synchronic and descriptive approaches has evidently caused the historical aspects of ethnomusicology to be left in a methodologically disorganized array. It is the purpose of this paper to work toward a systematization of the various historical aspects; it will utilize approaches followed in the past as well as other theoretical possibilities. Systematizations of this sort have already been attempted in ways which range from early musichistorical points of view such as Lach's (1924) through later ones which emerged under the increasing influence of anthropology (Kunst 1955:43-46; Nettl 1955a). The subject matter under consideration has also varied greatly. Beginning with historical speculation in Oriental music (with which we are concerned here only in a secondary sense because of the existence of at least a partially written tradition and a professionalized musical culture) and the role of folk music in the history of European cultivated music, the interests began to follow the trends of anthropological thinking, have occasionally gone their own way, and have sometimes been influenced by other disciplines such as biology and psychology. In spite of the variety of materials and aims, the historical aspects of ethnomusicology can be grouped into two principal classes, origin and change. Explanation of the origin of various phenomena has been at the root of many developments throughout the field, and has until recently predominated over the study of change. But while the study of origins has in a sense been exhausted or in many cases seems impossible to pursue further, the study of change promises to be of even greater interest when some of the methodological problems have been solved. The problem of origin can be approached in a number of ways. For example, one may be interested in the manner of origin of a given phenomenon, or in the place of origin. The manner-of-origin approach has been one of the more speculative sides of ethnomusicology, and has provided considerable common ground between that field and general music history. The problem of the origin of music itself falls into this class, although ethnomusicological data can only corroborate or, more frequently, negate. Nevertheless, some theories of the origin of music which indicate the special function of music in primitive culture and its close ties to religion are genuinely based on ethnological information (e.g. Nadel 1930). The search for the manner of origin of various generalized musical phenom-


We present here a software that generates an extended connectivity matrix from the SMILES code of a molecule. This extended connectivity matrix allows the determination of the atomic code for an atomic fragment and then the attribution of its lipophilicity contribution fi. Then, log P can be easily computed by summing the fi values. This program which runs on IBM PC or compatible systems, can be used by chemists or pharmaco chemists interested in the fast evaluation of the lipophilicity of a series of molecules.


The article focuses on the conflict between the generation of electric power and the multiple use of water in Brazil. Despite the existence of legislation that defines, in situations of scarcity, the priority use for human consumption and watering of animals, the recent water crisis reveals a series of conflicts involving the Brazilian Electric System, their companies and their management, and other uses such as irrigation, fish farming, transport and leisure activities. On the basis of the data relating to the behaviour of useful volumes of some of the main reservoirs of hydroelectric plants located in the Southeast, is considered the crisis in the availability of electricity in 2013-2014 period and its consequences. In particular, it is analyzed the conflict by the use of water in the Paraiba do Sul River occurred in August 2014.

This paper presents an analytical model for the microendmill dynamics, including the setup errors, the axial force, the sectioned tool geometry, and the actual crosssection of the twisted fluted section. Different tool geometries and tool-grinding errors can also be incorporated in the presented model. To include the shear deformations and rotary inertia effects arising from the stubby nature of the microendmill, the Timoshenko beam equations are used in the derivation. The boundary-value problem is derived for each of the shank, taper, and fluted sections of the microendmill, and a component mode synthesis technique is used to combine the individual sections. A new spectral-Tchebychev technique is utilized to obtain the numerical solution of the boundary-value problem without resorting to the finite-elements technique. As a result, a simple yet accurate description of the microendmill dynamics is obtained. The solution is experimentally validated in Part II of the paper.


According to Dietrich Bonhoeffer acting ethically is to love one's own land and become a neighbour to others. You learn to believe by participating completely in life and therefore to the being of Christ. Only a theology of life and for life is capable of overcoming the opposition between God and the world, recognizing the reality of God in the reality of the world. The mature Christian is not addressed to a "stop-gap" God because he is incapable of finding solutions or right answers, but he must profess his faith through responsible action.


Abstract In the paper the resource constrained project scheduling problem is considered. Two fully polynomial time approximation schemes (FPTAS) are constructed for the problem with bounded width of the partial order in two cases that are NP-hard in the strong sense. The time complexity of the FPTAS for the problem to minimize the project completion time is O (2 K KM (N 2 /ɛ) K ) operations. Here K is the width of the partial order, and ɛ is an accuracy of the obtained solution. For the problem to minimize the average job completion time, an FPTAS with the running time O (2 K KM (N 3 /ɛ) K ) has been proposed. As a corollary, there is an FPTAS for the job shop scheduling problem with a bounded number of jobs.

The mobility status of self and surrounding vehicles provides important information to various tasks in autonomous driving (AD) and intelligent transportation system (ITS). Accordingly, a precise, stable, and robust mobility tracking framework is essential. Compared with self-tracking that relies only on mobility observations from onboard sensors [e.g., global positioning system (GPS), inertial measurement unit (IMU), and camera], cooperative tracking markedly increases the precision and reliability of the mobility information by integrating observations from roadside units (RSUs) and nearby vehicles through vehicle-to-everything (V2X) communications in the Internet of Vehicles (IoV). Nevertheless, cooperative tracking can be quite vulnerable if there are malicious users sending bogus observations in the cooperative network. In this article, we present a malicious user detection framework, which includes two sequential detection algorithms and a secure mobility data exchange and fusion model to detect and remove bogus mobility information and integrate proposed detection algorithms with previous data fusion algorithms, which secures the cooperative mobility tracking in AD, ITS. Simulations validate the effectiveness and robustness of the proposed framework under different types of attacks.


This paper researches on the earnings management of Chinese listed companies after the application of new accounting rules,and how the earnings after earnings management influence the top executives compensation.The result suggests that there is a widespread earnings management through investment income among companies and investment income significantly improves the level of top executives compensation.In addition,this paper researches on the effect of shareholding structure on the earnings management and pay-performance sensitivity.The result also suggests that the degrees of earnings management and pay-performance sensitivity in state control and shareholder concentration companies are much lower than those in non-state control and shareholder dispersion companies.State control and shareholder concentration companies can restrain the earnings management,but can not improve pay-performance sensitivity.

The following cases with cupping of the atrophic optic disc and low ocular tension presented field changes which are not common to glaucoma, and remained stationary in their course for a long time. To study this phase, in which they also differ from the usual glaucoma, I have endeavored to follow up the cases which were reported in an article on "Association of Sclerosis of the Cerebral Basal Vessels with Optic Atrophy and Cupping," presented before this Society in 1932,1 and I am now ready to report on the subsequent histories of those that are available and several that have been added since that date, making 11 cases in all. In these cases a group can be distinguished where the field changes are altitudinal. These cases with altitudinal defects are frequently characterized by a stationary course.

OBJECTIVE
To investigate a new surgical method for the treatment of prostate cancer with bladder outlet obstruction.

METHODS
Forty-seven patients with prostate cancer complicated with bladder outlet obstruction were treated by combined use of transurethral electrovaporization ablation of the prostate (TUVP) and transurethral resection of the prostate (TURP).

RESULTS
The operations were successful, with satisfactory results and no serious complication. IPSS decreased from (26.5 +/- 4.8) pre-operatively to (8.5 +/- 2.2) post-operatively (P < 0.05); Qmax increased from (4.6 +/- 1.5) ml/s to (14.5 +/- 3.6) ml/s (P < 0.05); and PSA decreased from (58.1 +/- 7.2) microg/L to (3.6 +/- 1.8) microg/L (P < 0.01).

CONCLUSION
The combined use of TUVP and TURP is a safe and ideal method for the treatment of prostate cancer with bladder outlet obstruction.


In this paper, we present a theoretical analysis of the error with three basic Monte Carlo radiosity algorithms, based on continuous collision shooting random walks, discrete collision shooting random walks and stochastic Jacobi iterations. We show that the variance of these three algorithms is in practice to very good approximation identical, explaining empirical results obtained before. The derivation in this paper can easily be adapted in order to calculate the variance of other Monte Carlo rendering algorithms, such as stochastic ray tracing and density estimation as well.


Some applications of linear algebra were analyzed in this paper,such as solving the extreme value and limit of function of several variables,proving fundamental theorem of the calculus,integral,proving equality and inequality,which provided a new and effective method for solving some problems in higher mathematics.


In this study, published p-{rho}-T data of twelve muds are compared using three models already proposed. The empirical model suggested by Kutasov is found to represent the measured data more accurately than the other models for a majority of the muds. With the help of the empirical model, an explicit equation is derived analytically to predict static pressures at different depths. Based on the analysis, an equivalent static density (ESD) variable is defined that incorporates the mud p-{rho}-T behavior, pressure and temperature of the mud at surface, thermal gradient, and depth of the well. It is suggested that ESD should be used in place of normally used mud weight term in all phases of deep well drilling. The analysis is applied to a high-temperature, 25,000-ft deep example well. It is observed that static pressure or ESD at the bottom of the well decreases during tripping and the extent of decrease is dependent on the type of mud. For the example well, it is estimated that a maximum reduction in ESD of about 0.62 lbm/gal occurs in the case of 18-lbm/gal water-based-mud, and a minimum reduction of about 0.2 lbm/gal occurs in the case of a 11-lbm/gal diesel-oil-based mud.

The Al-Quran Wal-Hifz is one of the sections in Sharia subjects that employ the Dini Integrated Curriculum. This field calls for students to memorize several verses with the sentence meaning and the whole meaning of the surah. The objective of this research is to examine the methodology employed by teachers to fulfill this goal. The design of this study is a qualitative study comprising interviews with eight teachers who teach Sharia subjects in Government Facilitated Religious Schools (SABK) as primary sources, eight students together with the observation of teacher teaching as a source of support. The findings prove that teachers are positive and have about six teaching methods when teaching the Al-Quran Wal-Hifz such as singing, finger movement and hand gestures. Hence, this research is intended to be a guide for other teachers to be creative in their teaching.


Semantic Web is an open, distributed, and dynamic environment where access to resources cannot be controlled in a safe manner unless the access decision takes into account during discovery of web services. Security becomes the crucial factor for the adoption of the semantic based web services. An access control means that the users must fulfill certain conditions in order to gain access over web services. Access control is important in both perspectives i.e. legal and security point of view. This paper discusses important requirements for effective access control in semantic web services which have been extracted from the literature surveyed. I have also discussed open research issues in this context, focusing on access control policies and models in this paper.


This concept paper aims to identify learning using a metacognitive strategy in reading skill. The skill of reading and understanding text is a key goal to enhance knowledge and the key to success for an individual. In fact, in the learning of reading skill, a focus must be given to the aspects of comprehension and reasoning to achieve success in reading. In addition, the reader needs to know that the reading process is conscious and provides meaning to the reader. The reader needs to create awareness of his reading while focusing on the content of the text being read. By using an effective strategy while reading, the students may know and identify the level of reading comprehension. The metacognitive strategy needs to be applied during the reading process to make sense of the text. The metacognitive means the awareness of thinking or thinking about thought. The metacognitive strategy, too, refers to a way of improving the reading skill which is awareness that includes planning, monitoring, and evaluation. Students can apply the metacognitive strategy and control their learning through the process of designing what they want to learn, monitoring their learning progress and students can evaluate what they learn. The strategy found in the metacognitive can enhance students' learning and intelligence.


An embedded system is a combination of hardware and software designed to perform a dedicated function. Embedded systems typically come with stringent performance constraints such as throughput, latency, memory demands and resource usages. Deriving (or proving) that these performance constraints are satisfied in all possible circumstances is a challenging task due to increasing complexity of such systems. In this thesis, we focus on formal method-based performance analysis techniques for dynamic streaming applications using dataflow models of computation (MoC). Streaming applications are applications that transform input streams of data of indefinite length to output streams of data. They are considered dynamic if their computational and communicational requirements vary at run-time. Dataflow formalisms have been widely used to model and analyze streaming applications. Finite-state machine-based scenario-aware dataflow (FSM-SADF) is one of better-known MoCs used for modeling of dynamic streaming applications. In particular, FSM-SADF models the execution of a dynamic application as a sequence of fairly static modes of operation called scenarios. Each scenario is in turn modeled by a synchronous dataflow (SDF) graph. FSM-SADF allows rigorous design-time analysis and comes equipped with various worst-case performance analysis techniques. However, as the number of scenarios grows, FSM-SADF experiences compactness problems which in turn render it incapable of capturing applications exposing fine-grained data-dependent dynamic behavior. As the first contribution of this thesis we identify the semantic link between FSM-SADF and parameterized dataflow models based on SDF we refer to as SDF-based parameterized dataflow (SDF-PDF) by relating the concepts of FSM-SADF scenario and SDF-PDF configuration/instance. SDF-PDF, by using dynamic parameters has the ability of capturing fine-grained data-dependent application dynamics. By exploiting the semantic link with FSM-SADF we adapt the worst-case throughput and latency analysis techniques of FSM-


Abstract : The terrorist attacks of September 11, 2001 fundamentally changed our security environment. The system of strategic deterrence in place since the beginning of the Cold War visibly collapsed. Now we are trying to fashion a new strategic deterrence that relies not so much on retaliation as on prevention, either stopping the terrorists outright, deterring the sponsors, or convincing them that terror cannot succeed. To help us deal with the pressing problems of the post-September 11th world, we have three ongoing technological revolutions in sensors, information technology, and weapons. These technologies can enable us to think differently about how we organize and fight. Indeed, this is what network-centric operations are about. Their true impact derives from how they are applied. Narrowly applied, they would produce more efficient attrition, yet they clearly can do much more. The concept of effects-based operations is the key to this broader role. It enables us to apply the power of the network-centric operations to the human dimension of war and to military operations across the spectrum of conflict from peace, to crisis, to war, which a new strategic deterrence demands. The broad utility of effects-based operations grows from the fact that they are focused on actions and their links to behavior, on stimulus and response, rather than on targets and damage infliction. They are applicable not only to traditional warfare, but also to military operations short of combat. Effects-based operations are coordinated sets of actions directed at shaping the behavior of friends, foes, and neutrals in peace, crisis, and war. In brief, network-centric operations are indeed a means to an end, and effects-based operations are that end.


This paper aims to clear experimentally the influence of a coated cemented carbide tool and fluids on the surface roughness in the ultra-precision cutting of stainless steel SUS316. The experiments are executed by face-turning SUS316 with the cutting tool set on the ultra-precision lathe. The cutting fluids used are kerosene and water-immiscible cutting fluid. First of all, the influence of cutting fluid on the surface roughness is investigated. Kerosene is generally used as the cutting fluid in ultra-precision cutting of aluminum alloy, copper and so on. The surface measurement results indicated that the surface is rougher than Rz=100nm(P-V) at the short cutting length of 100m with kerosene. In the case of water-immiscible cutting fluid, on the other hand, the surface roughness is smother than Rz=50nm(P-V). Furthermore, it is found that the commercial coated tool is more useful for the ultra-precision cutting of SUS316 in no use of special equipments. The surface roughness of SUS316 is kept smoother than Rz=100nm(P-V) until the cutting length of 1,000m.


Hydrometallurgical processing of uranium-containing raw materials generates a significant amount of liquid industry-related waste, namely waste solutions that require disposal. Sorption is known as one of the most effective methods for purifying liquid matters contaminated with radionuclides. Various modification options are being developed for the purpose of using natural sorbents and increasing their sorption capacity. The authors proposed the methods for modifying natural aluminosilicate and coal-mineral raw materials. Zeolite found at the Kusmurun deposit and shungite from the Koksu deposit were selected for the research. The methods are based on obtaining solid-phase extractants. It was proposed to modify natural sorbents with a mixture of tributyl phosphate and di2-ethylhexyl phosphoric acid in kerosene, as well as a mixture of phosphoric acid and polyacrylamide. It was demonstrated that the first method is preferable for zeolite, and the second one for shungite. The research addressed the sorption properties of modified sorbents in static and dynamic modes. Uranium sorption isotherms were plotted. The maximum sorption capacity and the Langmuir constant were calculated. The research allowed synthesizing an organopolymer based on shungite, glycidyl methacrylate, orthophosphoric, and hydroxyethyl diphosphoric acids. Its sorption properties were studied under dynamic conditions. Its sorption capacity was assessed in comparison with modified natural sorbents.

Biel/Bienne is a bilingual (French and German), or rather multilingual (due to immigration) city in the Canton of Berne, Switzerland. Furthermore, because of the use of Swiss German dialects and Swiss Standard German, a diglossic situation can also be observed. This article presents some first results of a current study focusing on how the, often monolingual, French-speaking apprentices deal with this polyglottal situation and aims at revealing apprentices' language acquisition and the development of their competences during their apprenticeship. In Switzerland apprenticeships are carried out on behalf of a dual system. This means, that the apprentices usually spend one to two days at school doing vocational training and the rest of the week at their place of work. With the exception of language classes, schooling is usually solely carried out in French. However, the apprentices are exposed to multilingual and diglossic environments at their workplace. Consequently, the apprentices find themselves oscillating between monolingual and multilingual environments. The results presented here are based on the research gained during interviews with 20 apprentices and represent the apprentices' personal accounts.


Objective: To explore the Moderating effect of self-esteem on the relationship between peer victimization and children's problem behaviors. Methods: Multidimensional Peer-Victimization Scale, Rosenberg Self-Esteem Scale and Child Behavior Checklist-Teacher Report Form were used to investigate 993 children. Results: 1Physical and relational victimization were both positively related with children's internal and external problem behaviors. 2Self-esteem moderated the relationship between physical victimization and children's internal problem behaviors, and also moderated the relationship between physical victimization and children's external problem behaviors. At the lower level of self-esteem, physical victimization was positively associated with children's internal and external problem behaviors, but such association was not significant at the higher level of self-esteem. 3Self-esteem moderated the relationship between relational victimization and children's internal problem behaviors. Relational victimization was positively associated with children's internal problem behaviors at the lower level of self-esteem, but such association was not significant at higher level of selfesteem. Conclusion: Children with high level of self-esteem had little problem behaviors when being victimized by peers.


Objective To compare the difference in determination of residual free formaldehyde content in vaccine by various methods.Methods Standard formaldehyde solutions at concentrations of 0.25 ~ 100 μg / ml were tested by various methods to plot a reaction curve,based on which the liner range of each method was determined and verified by repeat tests and the calculation of correlation coefficients.The effects of aluminum adjuvant,centrifugation and additives on determination results were analyzed,and the methods were verified for suitability.Results The liner range of sulfurous acid-magenta method(Chinese Pharmacopoeia) was 25 ~ 100 μg / ml,while those of improved acetylacetone method and acetylacetone(Sinovac) method were 0.25 ~ 100 μg / ml,and those of acetylacetone(Crucell) method,acetylacetone(Pasteur) method and phenylhydrazine hydrochloride(MSD) method were 0.25 ~ 50 μg / ml.The correlation coefficients of standard curves of various methods ranged from 0.994 to 1.000.The recovery rates of aluminum adjuvant-containing samples before and after centrifugation were 18.06% ~ 76.00% and 17.19% ~ 75.95% by sulfurous acid-magenta method,88.28% ~ 103.21% and 95.43% ~ 102.78% by acetylacetone methods,and 99.27% ~ 117.74% and 100.55% ~ 119.40% by phenylhydrazine hydrochloride method,respectively.The recovery rates of samples containing additives determined by various methods were 94.68% ~ 101.86%.However,the recovery rates of samples containing formaldehyde determined by improved acetylacetone method(412 nm) was 100.84% ~ 105.88%,with a coefficient of variation of 0.28% ~ 3.08%.Conclusion Improved acetylacetone method is simple,sensitive,accurate,reliable and of a wide linear range,which is suitable for the determination of free formaldehyde in vaccine.


Abstract Observations by transmission electron microscopy on the decomposition of quenched and aged Fe-Sn, Fe-Sb, and Fe-Sb-Ni solid solutions show that precipitation of the equilibrium phase begins heterogeneously at grain boundaries and imperfections within the grains. The region of precipitation propagates by a discontinuous mechanism involving the formation of dislocations. The addition of 1 wt.-% Ni to an Fe-8 wt.-% Sb alloy was found to accelerate greatly the discontinuous precipitation.


This paper considers open loop control of linear, small amplitude waves on a fluid surface. It extends the controllability results of Reid and Russell [4] to a two-dimensional domain with irregular bottom contour, constructing a null control via its Laplace transform, provided the bottom has finite arclength and no beaches. The domain may be multiply connected, i.e. contain fixed objects, provided they do not touch the surface.


To determine the effect of body size on the clearance rate and ingestion rate of small intertidal bivalves, Glauconome chinensis, feeding experiments were conducted on individuals of 12 different size classes, from 4 to 16 mm in shell length. Relationships between morphological parameters were also determined. The clearance and ingestion rates of G. chinensis responded similarly to their body size, ranging from 1.3 to 28.2 mL/hr/ind. and from 24.0 to 458.5, ., respectively. Both rates increased significantly (p and ingestion rate decreased with increasing body size, with values from 1.0 to 3.1 L/hr/g and from 17.9 to 51.3 mgC/hr/g, respectively. The of G. chinensis was intermediate compared to those of larger bivalve species. The clearance rate (CR) relative to flesh dry weight (FDW) of G. chinensis were fitted well to the power function: . The exponent of fitting equation (0.71) of G. chinensis was higher than those of Mytilus edulis (Walne, 1972), Crassostrea gigas (Walne, 1972), and Placopecten magellanicus (MacDonald and Thompson, 1986).


This study aims to achieve an improved airfoil performance at low Reynolds number, and to determine the optimum position and size of rectangular cross-section burst control plate (BCP) to suppress stall in airfoil. The type of airfoil used in the present study is NACA0015 (National Advisory Committee for Aeronautics) airfoil with 200 mm of chord (c) length. Here, rectangular cross-section burst control plates with different sizes and at different locations are investigated numerically at the low Reynolds number of 1.6×105. Total of three positions (0.05c, 0.1c and 0.2c from the leading edge of airfoil), and four sizes (with heights 0.3 mm, 0.7mm, 1mm and 1.5 mm, and constant width 4 mm) of rectangular BCPs are simulated in ANSYS Fluent software using Transition SST model. The results indicate that the rectangular cross-section burst control plate is an effective device in the suppression of airfoil stall. For 0.7 mm and 1 mm height BCPs, the stall angle is postponed by 2° for all positions, while for 0.3 mm and 1.5 mm height BCPs, the reduction in sudden fall of lift can be observed but at the cost of reduction in maximum lift coefficient. Among various configurations, the 1mm height BCP located at 0.2c position is found to be most effective in the suppression of stall.

This study explored the antecedents and outcomes of negative emotional responses to climate change among people from a diverse range of cultural and national contexts. We analysed cross-sectional data gathered in 28 countries (N = 10,963). Our results show that negative emotional responses to climate change are positively related to the amount of attention people pay to climate change information, rates of exposure to information about climate change impacts, and perceived social expectations regarding emotional responding to climate change. Negative climate-related emotions were also positively related to pro-environmental behaviours and inversely associated with mental wellbeing. Notably, while negative climate-related emotions had a significant inverse association with mental wellbeing in all 28 countries, they only had a significant positive association with pro-environmental behaviour (46%) and environmental activism (25%) in a minority of countries. Our findings highlight the broad international significance of negative climate-related emotions as a plausible threat to mental wellbeing.


Industries have complained about poorly trained engineering graduates. The demand for higher qualified graduates is due to the fact that global competition has been intensified. It seems that the old fashion of extensive lecturing and evaluation of students' performance do not match with industries' needs in the competition of world markets. To resolve the existing mismatch between engineering curricula and industries' expectations, academia should take proper action. This paper is intended to present an alternative method of teaching, the "open end", a new approach of teaching engineering courses that brings the industrial atmosphere into the classroom.


Intermediate representations (IR) are a key issue both for compilers as well as for reverse engineering tools to enable efficient analyses. Research in the field of compilers has proposed many sophisticated IRS that can be used in the domain of reverse engineering, especially in the case of deep analyses, but reverse engineering has also its own requirements for intermediate representations not covered by traditional compiler technology This paper discusses requirements of IRS for reverse engineering. It shows then how extending and integrating existing IRS can meet most of these requirements. These extensions include a generalized AST and a mechanism supporting multiple views on programs. Moreover, the paper shows how these views can efficiently be implemented.


The MIT Plasma Fusion Center magnet technology development effort, in support of the DOE/PETC MHD program, has culminated in two recent innovations which, when combined, will not only improve the reliability of commercial scale MHD magnets but will also reduce their cost by a factor of two. The first of these is a new form of Cable In Conduit Conductor (CICC) designed specifically for large scale DC superconducting magnets and the second is a highly efficient, quasi-momentless force containment which is made possible by the new conductor.


We present a novel way to generate fuzzy membership functions that allows us to identify human activities from motion capture data. The system is able to recognise seven different boxing stances simultaneously with an accuracy superior to a GMM-based classifier. Experimental results seem to indicate that a template can be learned and a stance identified in under 10 milliseconds, which may allow recognition in real-time.

Abstract The flow of a liquid crystal around a body depends not only on the geometry of the body but also on the director field around it. For low-Ericksen number flows, the director distribution largely remains in its static equilibrium texture (along a uniform direction far away from the body and, for instance, perpendicular to its surface). We calculate the velocity and pressure of a cylinder in a nematic flow numerically, taking into account topological defects on the particle surface and find the drag force acting on the moving body. The drag force is, in general, non-central, i.e. not aligned with the direction of motion. The lift component of the drag force is a measure for the anisotropy of the system. We show that due to the realistic director texture the drag force is larger than previously thought and the anisotropy, FII/F^, smaller and decreasing while approaching the nematic clearing point.


A graph G(V, E) is said to have a vertex prime labeling if its edges can be labeled with distinct integers fromi»1, 2, 3, . . . , E i½such that for each vertex of degree at least 2, the greatest common divisor of the labels on its incident edges is 1. A graph that admits a vertex prime labeling is called a vertex prime graph. In this paper, we prove that mK3,3 and mK4,4 are vertex prime graphs, where m is any positive integer.


Abstract. The combination of photonic integrated circuits and free-space metaoptics has the ability to untie technological knots that require advanced light manipulation due to their conjoined ability to achieve strong light–matter interaction via wave-guiding light over a long distance and shape them via large space-bandwidth product. Rapid prototyping of such a compound system requires component interchangeability. This represents a functional challenge in terms of fabrication and alignment of high-performance optical systems. Here, we report a flexible and interchangeable interface between a photonic integrated circuit and the free space using an array of low-loss metaoptics and demonstrate multifunctional beam shaping at a wavelength of 780 nm. We show that robust and high-fidelity operation of the designed optical functions can be achieved without prior precise characterization of the free-space input nor stringent alignment between the photonic integrated chip and the metaoptics chip. A diffraction limited spot of ∼3  μm for a hyperboloid metalens of numerical aperture 0.15 is achieved despite an input Gaussian elliptical deformation of up to 35% and misalignments of the components of up to 20  μm. A holographic image with a peak signal-to-noise ratio of >10  dB is also reported.


Objective The pretreatment procedure for trimethlylamine-N-oxide(TMAO) detection in aquatic products by ion chromatography was established, and TMAO contents of common aquatic products from Qingdao local market was also measured in this study. Methods In this research, three pretreatments based on trichloroacetic acid, tris and trichloroacetic acid, tris and methyl cyanide were compared to investigate the effect of them on ion chromatography determination. Some of the most common aquatic products in Qingdao were collected for TMAO contents determination, which was conducted by non-inhibitory ion chromatography. Results Twenty-one aquatic products commonly seen in Qingdao were analyzed, and the test samples consisted of teleost, crustacea, shellfish and cephalopod. The content of TMAO in Illex argentinuscastellanos was shown to be the highest(8791.89 mg/kg). TMAO contents varied from 350 mg/kg to 2300 mg/kg in teleost. All crustaceans except Metapenaeus ensi contained TMAO with concents over 1700 mg/kg. All shellfishes contained TMAO with contents under 500 mg/kg. Conclusion In the twenty-one aquatic products analyzed, TMAO contents were high both in cephalo- pods and crustaceans, while lower in shellfishes. The general TMAO content trend might be concluded as cephalopodscrustaceansteleostshellfish.


Abstract Hydrodynamics of gas-liquid flow in a round-bottom stirred tank is modelled at two gas flow rates, constant bubble size and agitator speed of 300 rpm. A round-bottom tank equipped with four baffles and a Rushton turbine was chosen to represent a typical reactor used in hydrometallurgical processes operating under pressure. The applicability of different momentum interchange models and the Realizable k-ε, SST k-ω, and RSM turbulence models was studied using CFD software. The results were compared and validated against experimental data from Particle Image Velocimetry measurements by means of liquid and gas velocity distributions. In addition, energy balance between power input and dissipation energy was compared for the different turbulence models. The CFD model was found to be in good agreement with the measurements. Of the turbulence models studied, the Realizable k-ε model showed best agreement with the measured velocity profiles. Popular drag force models proposed in the literature were assessed, as was the influence of inclusion of non-drag forces. Gas flow was found to affect the liquid phase flow in the tank by generating an additional secondary circulation loop in the upper part of the reactor.

Abstract : This paper examines the military career of Maj Gen Benjamin Foulois to determine how his personal qualities and professional skill enabled him to rapidly build up and lead the air arm of the American Expeditionary Forces (AEF) to victory in World War I. While previous academic works have focused on Foulois s early aviation career from 1909 to 1916 and his tenure as chief of the Air Corps from 1931 to 1935, nothing details the vital role he played in the development of the American Air Service leading up to and during World War I. Foulois s personal and moral courage allowed him to take on the weighty responsibility of designing and executing a $640 million plan to create a combat air force from scratch. After his poor performance as chief of the Air Service, this same courage enabled him to learn from his mistakes and return to the Air Service staff to complete the organizational buildup he started. His skill as a political infighter gave him the insight to advocate patiently for the air arm s interests within the halls of the Congress and the War Department instead of following Billy Mitchell s example of using the blunt instruments of criminal accusations in the court of public opinion to effect change. Foulois s leadership record during the war was mixed; he was much more effective as a logistician and troubleshooter for solving the Air Service s training, aircraft production, and contracting problems than as a combat leader on the front. While Foulois was one of the world s first writers on airpower theory, he chose to focus his later career on developing the technological and organizational innovations he felt were required to bring the airpower theories of others such as Mitchell, Douhet, and Trenchard to fruition. Foulois s leadership, tenacity, forward thinking, and organizational skill hold lessons for future Air Force leaders charged with a similar rapid establishment or expansion of new capabilities, such as a robust remotely piloted vehicle force or a cy


Abstract Many Economics 101 students do not major in the subject partly to the subject content that emphasizes abstract models over contemporary issues including climate change, inequality, and financial crises. This critique is of both content and presentation. To this end an unorthodox review of salient ideas of text book by Reardon et al., Introducing a New Economics, is undertaken and paired up with video clips from movies and cartoons to amplify their reach.
