Critical nodes in networks are extremely vulnerable to malicious attacks to trigger negative cascading events such as the spread of misinformation and diseases. Therefore, effective moderation of critical nodes is very vital for mitigating the potential damages caused by such malicious diffusions. The current moderation methods are computationally expensive. Furthermore, they disregard the fundamental metric of information centrality, which measures the dissemination power of nodes. We investigate the problem of removing $k$ edges from a network to minimize the information centrality of a target node $\lea$ while preserving the network's connectivity. We prove that this problem is computationally challenging: it is NP-complete and its objective function is not supermodular. However, we propose three approximation greedy algorithms using novel techniques such as random walk-based Schur complement approximation and fast sum estimation. One of our algorithms runs in nearly linear time in the number of edges. To complement our theoretical analysis, we conduct a comprehensive set of experiments on synthetic and real networks with over one million nodes. Across various settings, the experimental results illustrate the effectiveness and efficiency of our proposed algorithms.


This artwork made using charcoal and graphite pencil, represents the mental state experienced by many patients post COVID19 infection who develop this chronic encephalopathy, known also as "brain fog "that is still not well understood and subject of ongoing research.


Objective:To study the effects of hypoxia on the expression of heme oxygenase-1(HO-1)in human bone marrow mesenchymal stem cells(MSCs).Method:Human bone marrow MSCs were isolated and enriched by Percoll density gradient centrifuge,then identified by flow cytometry.The anoxia model was set up by CoCl2.Real time fluorescent quantitative PCR was used to detect the expression of HO-1under the anoxic circumstance.Result:The surface CD34and CD45antigens were negative while CD13,CD44and CD71antigens were positive in MSCs.The expression of HO-1of MSCs significantly increased in a dose dependent manner after CoCl2treatment.Conclusion:Hypoxia can promote the expression of HO-1in vitro.


Mucoid impaction of the bronchi (MIB) is an unusual complication of adult asthma. In a review of 675 serial chest radiographs of 68 children and 2 adults with cystic fibrosis (CF), opacifications consistent with the diagnosis of MIB have been noted in 22 children and 1 adult, an overall incidence of 33%.
 The lesion of MIB in CF is a bronchusrelated complex of branched finger-like or nodular densities due to progressive distention of bronchi with tenacious mucopus. It is most commonly observed in the right upper lobe. Although it may spontaneously disappear, it tends to recur. Persistence of MIB for periods longer than 1 month can be related to subsequent bronchiectasis in the same segment. Clinical diagnosis is totally dependent on radiographic recognition, since symptoms and signs are characteristically lacking or non-specific. Atelectasis does not occur, probably because of collateral ventilation from adjacent uninvolved lung. Certain apparent differences have been noted between the adult (asthma) and childhood (CF) forms of MIB.
 Planigraphic and bronchographic studies in selected patients confirm the intrabronchial location of this process. Bronchial lavage is effective in washing out some impactions that have not responded to more conventional mucolytic and physical therapy.
 Recognition of MIB in a roentgenogram of a child should be considered presumptive evidence of CF, since similar opacifications are very rarely seen in children with other diseases. We believe that (1) progressive MIB at a subsegmental level is the major cause of bronchiectasis in CF and (2) secondary collateral ventilation may be the major cause of obstructive overinflation of the lungs in CF.


This paper gathers from the effects of the talents accumulation of the new perspective. After introducing the relative concepts and characteristics of the effects of the talents accumulation, it analyzes the environmental factor, which affects the talents accumulation. Then it judges the relative importance of these factors by the AHP. And on the basis of the AHP, taking Qingdao for example, it just evaluates the gathered environment of the science and technology talents. Finally, from the perspective of stimulating the presentation of the effects of the talents accumulation, it puts forward several measures to promote the gathered environment for the talents.


Applications for biomedical data processing often integrate external libraries and frameworks for common algorithmic tasks. It typically reduces development time and increases overall code quality. With the introduction of lightweight container‐based virtualization, the bundling of applications and their required dependencies has become feasible, and containers can be transferred and executed in distributed environments. However, the incorporation of unreviewed code poses a security threat as it might contain malicious components. In this paper, measures to minimize risks of untrusted application execution are presented. Based on the system calls issued during sample execution of the application, both the container itself and the container runtime configuration are restricted to the set of actions the application requires. It is shown that the employed security measures are suited to counteract different attacks while application runtime is not affected.


Abstract Aims: To summarize the relationship between vitamin D and infant asthma or wheeze. Materials and methods: We used PubMed and Embase to search articles through July 2017 with selection criteria for relevant studies. Random-effect models were used to pool the results of included studies. Results: Ten articles with 14 independent reports of 2073 incident cases of asthma and 1875 cases of wheeze among 23 030 pairs of mother and child were included in our meta-analysis. Compared to those who did not take vitamin D, the mothers who had vitamin D supplementation during pregnancy stage could reduce the risk of asthma or wheeze in infants. The combined odds ratio of infant wheeze was 0.65 (95% CI = 0.54–0.79) and asthma was 0.78 (95% CI = 0.69–0.89). The results almost did not change in the subgroup analyses. Conclusions: It suggests that increasing maternal vitamin D intake during pregnancy might have a protective effect on suffering from wheeze and asthma for children.


Considering the difficulties in covering fault in light supported caving face, the positioning instrument as the active means can solve the problem with described results.


Edrei and Szego5 [1] have posed the following problem: Giiven the Foiurier coefficients of a function G(x) find the Fourier coe/ftcients of the reciprocal of the function without actually evaluating G(x). They were able to solve this problem in the case that G(x) ?0. Unfortunately this restriction eliiniiiates the interesting case of complex-valued functions such as those which arise in Laurent series. In this note it is shown possible to obtain a solution withoutthe restriction, G(x) > 0. TFhis is achieved by first treating the more general problem of finding the coefficieiits of F(x)/G(x), given the coefficients of F(x) and G(x). Edrei and Szegd confine attentioni to classical Fourier series. Their problem is treated here for arbitrary orthogonal series expansions.2 Let 0j(x), j= 1, 2, , be a sequenlce of bounded orthoniormal functions in some region R of a space S. Thus


The effect of temperature on the purification abilities of water dropwort and watercress in eutrophic water with a planted floating-beds system (PFS) was investigated in this study. The results showed that the removal of NH+4-N,TN,TP,Chla,CODMn,and BOD5 was influenced significantly by growth at different temperatures (10,22,and 35℃). The removal rate of TN,NH+4-N,and Chla in the PFS were above 79%,82%,76%,respectively,at 22℃,and the removal rate of TP、CODMn、BOD5 in the PFS were over 75%,81%,80% respectively,at 35℃. The concentration of NO-3-N and NO-2-N in the PFS and non-planted FS (NPFS) decreased at 10,22,and 35℃,and NO-3-N and NO-2-N concentration in the PFS decreased significantly (p0.05). DO concentration in the PFS and NPFS at 10℃ was higher than that at 22℃ and 35℃ (over 1.2 times). In addition,there were significant differences between watercress and water dropwort for NH+4-N,TN,Chla,and CODMn removal at 10,22 and 35℃ treatments. These results indicate that watercress and water dropwort PFS have great potential for purifying eutrophic water,especially in low temperature seasons.


Most current on-line signature verification systems are pen-based, i.e., the signature is written by a pen on a digital tablet. To apply signature verification techniques to Internet applications, one desirable way is to use mouse as the input device. In this paper, a mouse based on-line signature verification system is presented. The signature data is represented in a compact and secure way. The enrollment is convenient for users and the verification can be real-time. The system architecture is a simple client-server structure that suits the common internet applications. The client side posts a sequence of X*Y to the server. That is, the raw signature sequence [X,Y] is represented by X+Y(dot sum of the X-, Y-coordinate sequences). Experimental results show that X+Yis effective for verification. Even if the sequence X+Y is intercepted during transmission over the Internet, original shape of signature [X, Y] can be recovered. To make the system easy to implement, the client side does nothing complex except posting X+Yto the server. The server side preprocesses the sequence and saves it to database during enrollment or match it against the claimed template during verification. The matching technique adopted here is the similarity measure ER2. Simulation results show that the mouse based verification system is reliable and secure for internet applications.


Sources excited by high frequency oscillators (or h-f sources) give high currents of positive ions, and are of current use in particle acceleraters, ion microscopes, and thermonuclear apparatus. Producing nearly monoenergetic ions, they are of value for mass spectroscopy. The papers about them, rather numerous, are related to very different matters, so that the data on these sources are found often in a more general study. This rather varied material was collected in order to state the conditions of practical use of the sources. After describing the usual models of h-f sources, they are classed according to the mechanism of the discharge (annular and linear, with or without addition of a constant magnetic field). Then, the problem of ion extraction; principal extraction systems and parameters influencing the intensity of the extracted stream. Finally, the average ion energy and the dispersion around this average value are given. (auth)


Abstract Studies of animal introductions have traditionally been the preserve of ecologists and natural historians but here it is argued that exotic species are a rich source of cultural evidence with the potential to enhance archaeological interpretations relating to human behaviour and beliefs. This paper focuses on the domestic fowl (Gallus gallus), a native of East Asia that spread across Europe during the Neolithic to Iron Age and became well established by the end of the Roman period. After reviewing the evidence for the diffusion of chickens and the concept of cockfighting, this paper presents a speculative argument about the impact of domestic fowl on Iron Age and Roman Britain. By drawing upon evidence from history, anthropology and human remains analysis, the article explores how the arrival of these new creatures may have helped shape human society, particularly in terms of gender definition and attitudes to violence.


Between 10% and 20% of bereaved individuals may suffer from complicated grief -- an admixture of symptoms of major depression and post-traumatic stress


An interesting class of scalar-tensor models, denoted by kinetic gravity braiding (KGB), has recently been proposed. These models contain interactions of the second derivatives of the scalar field that do not lead to additional degrees of freedom and exhibit peculiar features, such as an essential mixing of the scalar $\phi$ and tensor kinetic $X$ terms. In this work, we consider the possibility that wormhole geometries are sustained by the KGB theory. More specifically, we present the full gravitational field equations in a static and spherically symmetric traversable wormhole background, and outline the general constraints at the wormhole throat, imposed by the flaring-out conditions. Furthermore, we present a plethora of analytical and numerical wormhole solutions by considering particular choices of the KGB factors. The analysis explicitly demonstrates that the KGB theory exhibits a rich structure of wormhole geometries, ranging from asymptotically flat solutions to asymptotically anti-de Sitter spacetimes.


One might expect a book under this title to be simply an application of information theory, once very fashionable in psychology, to problems of sensation and perception. But the author declares that his ultimate concern is with the epistemological intuitions of George Berkeley, the 18th century English philosopher; information theory enters merely as a vehicle for expressing those intuitions in operational terms. Present-day perceptual psychologists, however, will be interested chiefly in the author's attempt to accommodate some ten empirical relationships ('laws') within a coherent mathematical theory, a theory consciously constructed after the pattern of physical science, borrowing especially from the ideal communication theory of Shannon (1948) and also from thermodynamics. Mathematical argument is more precise than verbal, permitting thereby the formulation of much more delicate arguments, but it is otherwise no different in kind. At the end of the day it has to make psychological sense, such as any verbal argument. The author may choose his symbols to signify what he pleases, but thereafter each formula is a precise expression which must transpose into some meaningful psychological statement. However, many readers will be sufficiently unsure in following the algebraic manipulations to be confident that their interpretation of the formulae is accurate. The chief task of this review, therefore, is to decode the principal equations and express their meanings in psychological terms. This is not a trivial matter. At the heart of the mathematical argument is the equation (page 140)


We present a result of localization for a matrix-valued Anderson-Bernoulli operator, acting on $L^2(\R)\otimes \R^N$, for an arbitrary $N\geq 1$, whose interaction potential is generic in the real symmetric matrices. For such a generic real symmetric matrix, we construct an explicit interval of energies on which we prove localization, in both spectral and dynamical senses, away from a finite set of critical energies. This construction is based upon the formalism of the Furstenberg group to which we apply a general criterion of density in semisimple Lie groups. The algebraic nature of the objects we are considering allows us to prove a generic result on the interaction potential and the finiteness of the set of critical energies.

Although previous research has provided indirect evidence that rhetorical questions can increase attitudinal resistance, what little work that was done was not specifically designed to examine the issue. Current models of attitude change suggest that rhetorical questions can increase persuasion and message processing, creating a relatively strong, resistant attitude. These processing and resistance effects in turn may be mediated by a property of attitude strength such as participants' cognitive responses. In Study 1, placing rhetorical questions in a message increased participants' message processing and counterargument generation relative to a control message. In addition, participants' attitudes were mediated by participants' cognitive responses. Study 2 found that a message containing rhetorical questions increased participants' attitudinal resistance to an attacking message more than a control message, and the resistance effects were related to participants' cognitive responses. These results provide the first direct evidence for the resistance effects of rhetorical question use and for mediators.


There is a strong demand for intelligent vehicle robots in many fields. They are expected to assist in our daily lives. In order to implement them in practice, the robots should include useful functions such as path planning, navigation, and obstacle avoidance. This paper focuses on obstacle avoidance control techniques for multiple obstacles. The vehicle used as a platform is a mecanum wheel omnidirectional vehicle, which is driven on floors and includes a mounted scanner range sensor. The presented algorithm has the advantage of reducing multiple obstacle avoidance control to a single obstacle avoidance control scheme. Finally, experimental results are presented in order to evaluate the avoidance algorithms. © 2010 Wiley Periodicals, Inc.

We propose a new method, named Support Vector Regression-based Active Subspace, for the reduction of the dimensionality of the high-dimensional input space of design parameters pertinent to the predictive assessment of the eye opening prediction of high-speed links with IBIS-AMI transmitter and receiver equalization. We compare the method with Support Vector Regression model and Principal Component Analysis-based dimensionality reduction algorithm. Numerical results show that proposed method exhibits the best accuracy in predicting eye height, eye width, and eye width at 10−12 BER in the presence of correlated design variability.


Scar surveys at regular intervals are a measure of BCG coverage in a population. BCG has been the main stay of tuberculosis control in Pakistan since 1952. To 1977 mobile teams were disbanded and responsibility for BCG was given to rural health centers and tehsil hospitals. Recently BCG vaccination has been integrated with extended programme of immunization (EPI). According to 1974-78 survey BCG scar was seen in only 94% of children between the ages of 0-14, while in Sindh it was only 4.9%. This was a poor result, confirming very low BCG coverage. The present study was planned to see the beneficial effect, if any, of BCG in making it apart of EPI programme by conducting a scar survey in Karachi school population.

52 Published By: Blue Eyes Intelligence Engineering & Sciences Publication Retrieval Number: H10100688S219/19©BEIESP  Abstract: A number plate contains a sign affixed to the front and rear of a vehicle for displaying its registration number. This registration number is used for the official identification purposes by the authorities. Most regular Optical Character Recognition (OCR) techniques perform well in recognizing printed characters on documents but cannot make out the registration number on the number plates. Besides, the existing approaches to number plate detection require that the vehicle is stationary and not in motion. To address these challenges to Number plate detection we make the following contributions: i. Use Neural Networks based Number plate character recognition, ii. Create a database of captured vehicle number plate's images, iii. Provide a client-server solution for quickly getting the details of a vehicle's ownership.


In order to select the compatible shade tolerant fodder crops under Ailanthus excelsa Roxb. studies were carried out at Forest College and Research Institute, Mettupalayam (T.N.) by planting four shade tolerant fodder crops viz., cowpea, sorghum, Desmanthus and Stylosanthus under fifteen year old Ailanthus trees. The observations revealed that the growth and yield of the test crops were reduced under intercropping when compared to pure cropping. Among the test crops, Desmanthus was most affected and fodder cowpea was the least affected. So fodder cowpea is identified as a best compatible fodder suited under Ailanthus excelsa .


The goal of the current study is to develop and validate a new chromatographic method for Fosfomycin Trometamol's determination in both pure form and pharmaceutical formulation. In the present study, a pre chromatographic derivatization of Fosfomycin Trometamol was done by forming an ion-pair complex of Heterocyclic nitrogen using the acidic dye methyl orange and phthalate buffer of pH-6. The yellow ion-pair complex was extracted with chloroform and it was further extracted with aqueous solution of 0.01M HCL. The ion-pair complex of Fosfomycin Trometamol and methyl orange obeyed Beer's law in the range of 30 -70 μg/ml with a correlation coefficient (r2) of 0.9946. A Liquid chromatography system equipped with an Agilent ACE C18 column (250 X 4.6mm, 5μm) was used as a stationary phase in this work. The developed method was validated according to ICH guidelines. For determining the medication in bulk and formulation, the devised approach was proven to be accurate, sensitive, and repeatable


Mild cognitive impairment (MCI) is an aging disease mainly caused by memory impairment after the occurrence of brain lesions. EEG analysis is an effective non-invasive method to recognize brain activity and MCI. Due to the highly non-stationary characteristics of EEG, it is a challenging task to extract features from EEG signals and further improve classification performance for MCI. In this paper, we will present a novel deep learning approach for MCI based on convolutional neural networks (CNN) using EEG signals, where the CNN is used for feature extraction from EEG signals in cognitive tasks, a softmax function is utilized as classifier and creatively the attention mechanism is applied to one of the convolution operations. Experimental results show that the CNN with attention mechanism has an average accuracy of 79.66% (validation) after the accuracy of the validation set has stabilized, which is significantly higher than that of traditional convolutional networks. Compared with the highest accuracy of 70.09% in the other four existing approaches, it shows an obvious advantage. The proposed approach can enrich the convolution features of EEG, improve the model fitting ability and generalization performance, and realize the classification of MCI effectively.

The problem posed in this paper is to give a relation connecting the noise stability of a communication system in which error-correcting codes are used to the parameters of these codes. The amount x of code combinations is found, which differ from each other by not less than a given number of elements for a given arrangement of all the possible combinations. It is proved that the quantity x depends on the arrangement of the primary combinations. Inequalities are obtained for the greatest amount of combinations x_m , for which any two differ by not less than d elements for small and large values n of the common number of elements in each code combination. It is established that the probability of distortion, p_n , of a code group in a system with correcting codes satisfies the inequality p_n , where p is the probability of distortion of one element. The shape of the f(p, n, d) function is found for large values of n . Graphs of this function are constructed.


In a 1992 essay, Ruth Wilson Gilmore relates her father's reaction to seeing her perform in an undergraduate production at the elite university in which she was enrolled and by which he was employed. "Are you going to act," she recalls him asking her, "or are you going to work?" Gilmore never shares her response to this unanswerable question in the text. Instead, in an explication of the dialectical tension indexed by her union- and communityorganizer father's challenge, she poses one of her own: "Who works and what works, for whom, and to what end?" 1 It is to this second question and its implications for the academy that Gilmore returns in her 2010 presidential address; as more than a few have noted, she could not have done so at a more urgently necessary time. 2 She tacks between places and times to tease out how we continue to make our lives work (that is produce value), and how that work can make life amidst the anti-state state's conjoined death-dealing processes of structural adjustment and security enhancement. The resulting meditation not only delineates who works—as academics, we do, a fact that constitutes both our power and our responsibility to other workers—and what works—organizing in all of its forms including policy, research, teaching, writing, and building unions and coalitions. Even more significantly, Gilmore points to how we can make that work work for ourselves and for each other, towards and in the service of freedom. The content, she posits, is abolition; the form is organizing; the method is dialectical. Culture and politics, imagination and analysis, history and futurity, the image and the word: "The substance of the distinction," Gilmore tells us, "is dialectical, and the tendencies along which the tension both pushes and pulls me are what inform the semiotics and histrionics of my critical performance." 3 These lines, written some years ago, could just as well be describing this November's presidential address. Indeed, what follows responds to Gilmore's address as a critical performance, by which I mean that it is as much a reading


An analysis of three types of detectors used for dose calculation and verification during total body
irradiation (TBI), procedure is presented. Doses were traced in ten points representative for body anatomy on beam entry and exit. To verify the calculated doses, a set of semiconductor, thermoluminescent and ionization detectors has been applied. Application of each type of detector has been discussed and their response to dose in TBI condition evaluated. The accuracy of dose determination between 2.6% to 3.3% on entry and 5.8% to 7.7% on exit was achieved depending on the type of detector.


The genetic polymorphism of GlyCAM1 gene exon 3 and intron 3 in 273 heads of China Holstein cow were studied by CRS-PCR and PCR-SSCP and DNA sequencing.The results showed that two polymorphic sites were identified,which were located at position 2081(A/C) and 2417(C/T) in the GlyCAM1 gene exon 3 and intron 3,respectively.At the 2081 site and 2417 site,the allelic frequencies of A and B were 0.752 5/0.247 50 and 0.904 6/0.095 4,respectively.χ2 adaptability test indicated that the polymorphic site 2417 was in accordance with the Hardy-Weinberg equilibrium(P0.05) in China Holstein cow.But the polymorphic site 2081 was not in accordance with Hardy-Weinberg equilibrium(P0.05).Meanwhile,the results indicated that the mastitis were significantly affected by fetal effect(P0.01) and field effect(P0.01) and lactation month effect(P0.05).At the 2081 site,SCS was significantly affected by genotype effect,which the cow with genotype AA showed lower somatic cell score than that of genotype AB and BB(P0.05).


Objective To evaluate the effectiveness of health education among patients with benign prostatic hyperplasia (BPH).Methods We have conducted multiple health education programs among patients with BPH.Afterwards a questionnaire-based survey was conducted among 80 patients to evaluate the effectiveness of these programs.Results The awareness rate of BPH reached 95.00% (76/80) after health education,which was significantly higher than that before health education (31.25%,25/80).Patients tended to adopt more healthy lifestyles after health education.Conclusion Most aged men are not aware of the risks and progression of BPH.Effective health education can increase their awareness of BPH and urge them to adopt healthy lifestyles.


It has recently been established that the porosity of surfaces can have a significant effect on the reflection geometry of shock waves, and thus on the loads that are generated. This paper describes a comprehensive series of tests on the patterns of shock wave reflection from a surface covered with a series of slits, over the full range of angles of incidence from glancing to normal. The use of double-pulse interferometry is shown to be ideally suited to the study of complex compressible flow fields of this type, not only because of the high resolution but also because the tracking of fringes gives a very clear indication of both the general flow field as well as the fine structure, and thus helps clarify the mechanisms whereby the interaction process is modified from the case of reflection off a plane impervious wall. These features of the method allow a number of effects to be established which have not previously been evident, or are in conflict with the assumptions of previous studies. Specifically it is shown that the inflow angle relative to the plate is almost constant (at about 17 degrees) for shock incidence angles from zero to about 50 degrees and that the flow leaves the plate almost normal to the surface; although there is a slight drift in a direction opposite to that of the shock induced flow. Furthermore it is shown that many of the flow variables, and specifically the inflow velocity, exhibit a maximum in the vicinity of transition from regular to Mach reflection. An analysis of the motion of the acoustic waves generated from the lips of the perforations allows estimates to be made of the constancy of the inflow along the surface. These waves are convected with the flow and as they do not meet the wall at a right angle show that the convection is towards the wall. Using this method it is found that the inflow is constant behind the reflected wave in regular reflection but variable for the case of Mach reflection. Photographs of the region under the plate clearly show how the wavelets emerging from the perforations coalesce to form a transmitted wave. Measurements of this wave enable the pressure below the plate to be assessed and thus to obtain an estimate of the pressure drop across the plate. A striking feature on the underside of the plate is that the contact surface separating flow that was initially above the plate from that engulfed by the transmitted shock is made up of a string of vortices arising from the wave diffraction into the perforations.


Objective:To study the changes of MMP1,MMP3 and IL-1content in synovial fluid of knee osteoarthritis patients before and after arthroscopic debridement.Methods:A total of 60 cases of knee osteoarthritis admitted from 2011 May to 2013 December were enrolled and treated with arthroscopic debridement.Before surgery and 3,6,12 months after surgery,knee joint function and MMP1,MMP3 and IL-1content in synovial fluid were compared.Results:3,6,12 months after surgery,MMP1,MMP3 and IL-1content in synovial fluid were lower than those before surgery;knee maximum extension angle and maximum flexion angle were higher than those before surgery;MMP1,MMP3 and IL-1content in synovial fluid were negatively correlated with knee maximum extension angle and maximum flexion angle.Conclusion:Arthroscopic debridement surgery can reduce MMP1,MMP3 and IL-1content in synovial fluid and improve knee function.


Superfood is an informal term for foods that benefit the body in many different ways. Superfoods help to meet several dietary needs and are great sources of essential vitamin and minerals also fight disease and sickness, making them powerful anti-aging tools. Some super like avocado, rambuten, dragon fruits blackberries, blueberries, corn, garlic, ginger, onion berries, etc. All foods that have been associated with preventing age are called antiaging foods. The aging process is natural to life for every person. There are many products and methods to prevent and reduce aging, from antiaging skin care The study was carried out to determine the different types of superfood product and shilf life (packaging) of orange squash and ginger ele juice, kiwi sherbet produced were prepared and were processed into juices and sensory analysis of the juices were done. Fruits juices of orange, which was stored for 6o day in orange squash, and ginger ele, product were pressurization and storage in packaging glass bottles (250ml). Sensory evaluation showed that there was no significant difference among the juices from four samples considering color and overall acceptability. But considering flavor and texture, there was significant difference among the juices from three samples and sample 3 was the best. However, the shelf life of juice was established within 30 days.


Opius melleus was originally described in 1915 by Gahan (2j p, 73) from one female specimen found on Mount Washington, N. H., and was almost simultaneously described by Kichmond (reported by Woods (10)) as Biosteres rhagoletis from 21 specimens reared from puparia of Rhagoletis pomonella from blueberries collected at Cherryfield, Me. In 1919 Gahan (4) cited B. rhagoletis as a synonym of 0. melleus, and in the same year (3) he described two additional species, 0. richmondi and 0. lectus, both of which, he states, were swept from blueberry barrens in association with 0. melleus and may also parasitize B. pomonella. Woods (10) was the first to rear 0. melleus from puparia of the blueberry maggot, and he states that Severin reared it from the apple maggot. Good {5) described the method of oviposition into the apple maggot. Lathrop and Nickels (7) summarized the life history of 0. melleus, gave tables indicating the percentage of parasitism of the blueberry maggot, and showed that this parasite could remain in the soil as long as four years and then successfully emerge as an adult. During the present study Opius melleus proved to be the dominant parasite of the blueberry maggot in Washington County, Me., and was found in sufficient numbers to indicate that it is an important factor in the economy of its host. 0, richmondi, reared in small numbers, was insignificant in comparison with 0. melleus. No specimen of 0. ledus was observed in the cages. If 0. ledus parasitizes the blueberry maggot at all, it must be a minor species in eastern Maine. SOME HOST RELATIONSHIPS


Hidradenitis suppurativa (HS) is a chronic relapsing disease that frequently causes disabling pain, diminished range of motion, and social isolation. In advanced cases of HS, aggressive excision of the involved apocrine tissue with subsequent reconstruction is the definitive treatment. Here, we present our recent experience of using split-thickness skin graft (STSG) for managing an extensive defect following wide surgical excision of axillary HS lesions. Adequate wide excision of the infected tissue ensures complete skin-graft take while allowing full shoulder mobility, thereby minimizing undesirable outcomes. No limitation of shoulder joint or disease recurrence was observed during one year of follow-up. This method has satisfactory aesthetic and functional results as well as low donor site morbidity for treatment of repeated extensive HS of axilla.


Abstract In this paper, we study vector-valued multiresolution analysis on local fields of positive characteristic p. The associated subspace V0 of L 2 (K,ℂ N )$L^2(K, \mathbb {C}^N)$ has an orthonormal basis, a collection of translates of the scaling function ϕ of the form {ϕ(t-u(k))} k∈ℙ $\lbrace \varphi (t- u(k))\rbrace _{ k \in \mathbb {P}}$ , where ℙ={0,1,2,...}$\mathbb {P}=\lbrace 0, 1, 2,\ldots \rbrace $ . We find the necessary and sufficient condition for the existence of associated wavelets.


The need to understand the relation of man to food, determines the existence of appropriate behavior as well as an attitude in accordance with the modalities that determine human development and evolution, under this structural aspect. A proper diet is the one that provides the amount of nutrients corresponding to personal needs. The food pyramid is the scheme we refer to most in order to know the proportions of foods recommended for consumption. It is a pyramid divided into "layers", each corresponding to a category of foods and the respective quantity.

Objective To identify the sources and levels of stress among baccalaureate nursing students who haven't been in clinical practice, and to explore the effect of stress management on stress levels of them. Methods A qua-siexperimental pre-test post-test design was used in this study. Eighty students in the second and third year from Nursing School of Jilin University were selected as the subjects of the study. The subjects were allocated to the experimental and control group randomly with 40 subjects in each group. Data were collected by means of a questionnaire consisting of two parts: a demographic profile and Beck-Srivastava Stress Inventory (BSSI). Students in this study were taught stress management strategies which included understanding concepts and theories of stress, time management, relaxation skills, nutrition and exercise, and positive belief on life. Results The major sources of stress in baccalaureate nursing students who haven't been in clinical practice focused on the academic area (The stress level of the subjects before intervention were considerably higher than the accepted cut-off score (P0. 01); The mean score of stress level of the experimental group after intervention was lower than the control group(P 0.05). Conclusion The stress management program of this study had some positive impact on the stress levels of baccalaureate nursing students.


Nuclear Magnetic Ressonance (NMR) is a widely used technique, with a long history of applications in chemestry, medicine, and material science. Twenty years ago, it emerged as a reliable source for quantum computing too, since the work of Cory et al. [1]. One of its major advantage is the ease with which arbitrary unitary transformations can be implemented, together with its experimental simplicity, that can be traced back to very simple NMR routines, which were being extensively used long before. However, some disadvantages came along, mostly related to experimental effort in the initialisation and measure processes, and scalability. In this work, we have successfully probed some simple quantum gates (Pauli-Z, Pauli-X and Hadamard) in one and two-qubit systems, realised in a NMR experiment. The work comprised a pseudo-pure state preparation, followed by the application of the gates, and a quantum tomography method, necessary to reconstruct the density matrix. The experiments were conducted with a chloroform sample, placed in a 300 MHz Bruker Avance II spectrometer, equipped with a superconducting magnet with a 7 T magnetic field.


This article deals with the performance of Bluetooth scatternets in a real-life environment where different queues are implemented with finite buffers. Finite buffer size will introduce packet blocking at different queues along the packet path, which in turn causes changes in effective traffic load as well as retransmissions and ultimately affects end-to-end packet delays. The authors assume that the piconet masters use E-limited intra-piconet polling, while bridge scheduling is performed using the walk-in approach without rendezvous points. They present a detailed simulation model that allows them to obtain accurate measurements of blocking probabilities, end-to-end-packet delays, and overall throughput in the network as functions of network and device parameters. Some practical recommendations about the buffer size that will keep the blocking probability within reasonable limits are also given.


The objections which have been made to testing statistical null hypotheses as the means of analysing the results of psychological research are assembled. None of these criticisms is by itself new, and none is controversial. Together, however, these criticisms demand a fundamental change in the way we analyse the results of psychological research and the way in which we teach students to analyse data. In order to cumulate a reliable body of knowledge, psychologists should dispense with statistical hypothesis testing and instead use empirical replication as the test of reliability, and should report effect size measures together with an indication of their likely error.


Comment on: Transient effect of suction on retinal neuro-vasculature in myopic patients after small-incision lenticule extraction In the study by Liu et al., they evaluated retinal tomography and vascular features after small-incision lenticule extraction. The postoperative evaluation was performed at day 1 and day 7. On reading the methods, it was clear that no adjustment to the axial and lateral dimensions was performed as a result of the change in the axial length after small-incision lenticule extraction. Axial length changes after refractive surgery because of the change in the thickness of the cornea. Refractive surgery caused a change in the magnification of the optical coherence images acquired postoperatively. It was surprising that neither the authors of the study were aware of this or the reviewers raised this concern. This brings into question the accuracy of all the results presented in this study.


The current research aims to explore the effects of COVID-19 on students' academic achievements during the quarantine period through online mode of education and the effects of stress and anxiety on students' learning during quarantine. The nature of the study was descriptive research using validated close ended 5 point Likert scale questionnaire as tool of data collection. The questionnaire contains two main themes followed by ten items in each theme. The data was collected from 150 undergraduate level students via Google form, which was analyzed through Ordinal Regression Analysis (ORA). The results of the study show that attitude of students towards online classes was negative, quarantine period was difficult for students and leads to psychological issues. The study recommends that mental exercise be given to students to abstain from psychological stress and motivate the students towards online mode of teaching and learning process.


This article finds its impetus in the curious convergence of three twenty-first-century horror films around the ambiguous 'It' foregrounded by their titles: Andrés Muschietti's 2017 adaptation of Stephen King's 1986 novel It, David Robert Mitchell's 2014 It Follows and Trey Edward Shults's 2017 It Comes at Night. In each of these films, the titular 'it' is difficult or impossible to pin down; it can assume the form of anyone (or, in the case of Shults's film, infect anyone) and appear anywhere; it cannot be reasoned with, explained or swayed from its course; and conventional sources of protection – the law, and particularly the family – all come up short when confronting it. In this way, the ambiguous 'its' of these three films can be seen as crystallizations of a twenty-first-century zeitgeist in which monstrosity seems particularly difficult to locate and defuse. In the age of terrorism, mass shootings and 'stranger danger', climate change, and global pandemics, these films suggest that contemporary anxieties cluster around the ambiguous nature of modern threats.


This study was conducted in the northern part of Kenya, Turkana district, in Kakuma division. Its aims were to study the impact of human settlement on vegetation and soil resources and the socio-economic environment. Kakuma is a semi-arid area under nomadic pastoral ism as the main activity. This area has a high population concentration than other areas. The presence of the refugee camp has attracted many people from within the turkana community and also the outside community. This has in turn had an effect on the vegetation and the social patterns of the local community. Vegetation plays an important role in the sustenance of the Turkana people, either directly (food) or indirectly (forage for animals). For the study of vegetation, 4 transects, each 6 Km long, were laid from the settlement camp. Vegetation density, cover and diversity values were taken for trees, shrubs and herbs at the intervals of 1 Km. The 6th Km from the settlement camp acted as the control. There was a significant difference (P>0.05) in vegetation cover, density and diversity along distance gradient. The mean tree crown cover was low near the settlement camp-6.24%, but high away from the settlement camp-57.69%, as many trees were cut down for charcoal burning, firewood and building poles. The density was high near the settlement camp as many trees were re-sprouts and young trees. The cover of thic was low compared to mature trees. Shrub crown cover was low in the 1st and 4th Km, 0.87% and 3.54% respectively, compared with 6.84%, 9.82% and 7.8% for the 2nd, 3rd and 5th Km. Areas around the 1st and 4th Km had settlements. The need for fencing and building materials was the main cause of low shrub cover. The density of the shrub species generally increased as one moved away from the settlement camp. Shrub species most cut were Acacia reficiens, Acacia mellifera and Abutilon fruticoswn. Herb species cover and density was high near the settlement camp 68% and 202.17 individuals/m2 compared to 45.43% and 187 individuals/m2 at the 6,h Km., but this comprised mostly of species unpalatable to livestock like Tribulus terrestris and Portulaca oleraceae. Though herb cover was low away from the settlement camp, the proportion of palatable species was high. Species diversity was low for trees and shrubs near the settlement camp but high for herb species. Direct cutting into tree and shrub species must have reduced the number of species available. The high number of herb species was a result of over-utilization of palatable species. The region in the recent past has undergone various ecological and social changes due to various factors. The study revealed that droughts and livestock raids in the previous years have set in motion social and ecological changes. The loss of livestock through raids and droughts has encouraged the sedenterization of the Turkana. Many families opted to settle after losing their livestock and abandon their pastoral lifestyles. This has not only affected their cultural patterns but has had an effect on the rangeland condition. Lack of mobility had concentrated livestock in specific areas depleting the forage resources and creating conditions for soil erosion. The study revealed that the range condition was poor near the settlement camp. The Turkana population near the settlement camp consisted mainly of the destitute families who had lost their livestock in raids and droughts. The refugee camp within the division has been their main source of income especially through trade. Trading activities included the sale of cereals, clothing materials and household goods to the Turkana. They occasionally exchanged the items with livestock. At the same time the Turkana sold building materials and wood-fuel to the refugees and people within the settlement camp. Apart from this they also sold livestock to the refugee camp. The most common sold livestock were goats and camels. Apart from trading activities they also came to Kakuma in search for employment mostly in the refugee camp. School enrolment was low as many school-going age children opted to look for a part time work within the refugee camp to earn some money. Though there were already some changes in the pastoral lifestyle of the Turkana around the Kakuma area, the introduction of the refugee camp has hastened the process of change. The increase in population has set in motion various changes that have affected not only the vegetation but also the social structures within the Kakuma area. In regard to this there is a need for education on the impacts, both short term and long term, of the various activities on the vegetation, livestock resources and also the pastoral lifestyle. This is also necessary since the refuge camp may be relocated or closed down in future.

Exclusive breastfeeding during the first 6 months of life has been identified as one of the key interventions for reducing childhood deaths in a group of articles on child survival published in LANCET. As a global public health recommendation infants should be exclusively breastfed for the first six months of life to achieve optimal growth development and health. A recent trial has shown that early initiation of breastfeeding could reduce neonatal mortality by 22% which would contribute to the achievement of the Millennium Development Goals. Globally over one million newborn infants could be saved each year by initiating breastfeeding within the first hour of life. In developing countries alone early initiation of breastfeeding could save as many as 1.45 million lives each year by reducing deaths mainly due to diarrhoeal disorders and lower respiratory tract infections in children. Early breastfeeding practices determine the successful establishment and duration of breastfeeding. WHO recommends early initiation of breastfeeding (i.e. within one hour of giving birth). Early breastfeeding within 1 hour and exclusive breastfeeding for first 6 months are the key interventions to achieve reduction in child malnutrition and mortality. NFHS-III data shows that initiation of breastfeeding within 1 hour is only 24.5% while exclusive breastfeeding rates in children <6 months is only 46.4%. The present study was hence conducted to study the prevalence of Breastfeeding practices including time of initiation giving colostrums prelacteal feeds and Exclusive Breastfeeding (EBF) among infants (up to 6 months of age) in urban slums of Vadodara city. Research Question: What are the feeding practices in infant's upto 6 months of age? Settings: Urban slums Study Designs: Cross sectional study Participants: 192 infants upto 6 months of age were selected. Methodology: Cluster sampling Results: Early initiation of breast feeding was seen in 75% of infants. Pre lacteal feed was given in 36% of infants and colostrums was given in 87% of infants. 15.5% infants received exclusive breastfeeding while majority (76.8%) were given water with breast feeding. Still early initiation of breast feeding and exclusive breast feeding is not practiced at a desired level.


Alterations in the function of androgen receptor (AR) and its signaling pathway may be responsible for the progression of prostate cancer.

The effect of temperature on the process of dry anaerobic fermentation was studied. Result showed that the temperature had great effect on pH. Among three groups, pH decreased rapidly to the lowest at 55℃. In test of middle and normal temperature change of pH was slower. The acid was accumulated in experiment of normal temperature and pH was at lower level. The pH was returned to normal in post period.. It was much remarkable that the temperature had impacted on ORP. Eh decreased very soon at initial stage and was little change when reached to the lowest. The change of ORP order was normalmiddle high temperature experiment. The clearance rate of VS was 36.44%, the highest in high temperature test. The effects of gas production and methane content were the best, 2548mL and 62% respectively. The time of gas producing was the longest.

Nowadays natural habitats are imperilled because of human landscape-transformer processes and negative effects of climate change. The wetlands are sensitive to changes in their environment, their degradation time is 5-10 years, their recovery time is 10-30 years (Szabo, 2004.) Watery habitats belong to the most vulnerable lands because low rate of anthropogenic effects can lead to significant and fast changes in these places. The condition of Lake Nagyszeksos and the anthropogenic effects indicated by physical-chemical processes were studied in our work. The studied saline area reflects well the regional environmental and climatic changes. Soil- and water-chemical measurings and examinations were carried out. In this paper we present a part of ones. On the basis of the investigations we compiled parameter maps of the studied area which were useful revealing of (1) the sensitive areas, (2) changing of the nutrients ratios and (3) the changes because of the cultivation of the neighbouring fields. Our results are help (1) to operate of the water buffalo pilot ecofarm (2) to determine the new rehabilitation plans and (3) to define the quantity and type of the new turism investments.


Objective To observe the influence of four kinds of cytokine (CK) units on differentiation, proliferation, and development of murine bone marrow-derived dendritic cells (DC) in vitro . Methods DC generation from murine bone marrow cells was induced with different CKs. Then DCs were analyzed by FACS to determine the proportion of CD11c+ cell, the expression of MHC class II , and the expressional change of CD86 after being stimulated by lipopolysaccharides (LPS) . Results The ability of GM-CSF + IL-3 + SCF to promote the differentiation and proliferation of DCs was obviously better than that of other three groups ( P 0.05 ) . The increased expressional extent of CD86 in group of GM-CSF + IL-3 + SCF was remarkably less than that of group of GM-CSF + IL-4 (P 0.01). Conclusion The combination of GM-CSF, IL-3, and SCF can synergistically promote the differentiation and proliferation of DCs generated from murine bone marrow cells, and the majority of these DCs are DC precursors.

The interest of Construction investors towards Data Centres is a novelty that however is not supported by an adequate level of knowledge of the technical characteristics that distinguish this particular building type. In fact, these are complex buildings, which are rarely dealt with in the literature (real estate and construction) and very different from the typical asset class of the real estate market, for which it requires a very high level of specialization. From an investor's point of view, although there are some reference standards that define some minimum quality standards, we need to widen our attention, focusing on all the technical / technological factors that influence the business model. The paper deals with this problem, trying to identify the different elements that influence the risk profile of the investment (thus omitting risk factors of another kind) and structuring them in clusters. Specifically, the paper focuses on the cost factors (passive cycle of the business model) that accompany the investment or the real estate asset "data centres" in its life cycle.


Objective To evaluate the clinical value of spiral CT angiography in diagnosis of the pathogeny of the spontaneous subarachnoid hemorrhage(SAH)Methods The axial source CT images were obtained in 39 SAH patients by using spiral CT scaning,contrast scan 3D reconstruction-CTA,and dealt with the technique including shaded surface display and maximum intensity projection.Results Among 39 cases,there were 20 patients with cerebral aneurysms,11 intracranial AVM s,3 cerebrovascular malformations,2 moyamoya diseases,1 meningioma,2 normal.There was no secondary nerve injury and neurological complication. Conclusion 3D-SCTA images can provide useful information about the site,shape,size and orientation of intracranial aneurysms and vasoular malformations.


It is important to study the humidity distribution in manned spacecraft habitation cabin. Because of the apparatus shape and structure's complexity it is difficulty to make analyse model, so the apparatus within the cabin are reasonably chosen and simplified by using the principle of velocity gradient and humidity gradient magnitude. A finite-element grid based control volume method is adopted to discrete computation field, the moisture mass concentration distribution is obtained through the solution to the discrete equations,finally according to temperature distribution and definite conversion relation,the relative humidity distribution is also obtained. The numerical analysis result indicates that the relative humidity is a little high, so it is necessary to take more measure to improve the humidity environment in the cabin.


The National Ignition Facility (NIF) requires diagnostics to analyze high-energy density physics experiments. As a core NIF early light diagnostic, this system measures shock velocities, shock breakout times, and shock emission of targets with sizes from 1 to 5 mm. A 659.5 nm VISAR probe laser illuminates the target. An 8-inch-diameter fused silica triplet lens collects light at f/3 inside the 33-foot-diameter vacuum chamber. The optical relay sends the image out an equatorial port, through a 2-inch-thick vacuum window, and into two VISAR (Velocity Interferometer System for Any Reflector) interferometers. Both streak cameras and CCD cameras record the images. Total track is 75 feet. The front end of the optical relay can be temporarily removed from the equatorial port, allowing for other experimenters to use that port. The first triplet can be no closer than 500 mm from the target chamber center and is protected from debris by a blast window that is replaced after every event. Along with special coatings on the mirrors, cutoff filters reject the NIF drive laser wavelengths and pass a band of wavelengths for VISAR, for passive shock breakout light, or for thermal imaging light (bypassing the interferometers). Finite Element Analysis was performed on all mounting structures. All optical lenses are on kinematic mounts, so that the pointing accuracy of the optical axis can be checked. A two-color laser alignment scheme is discussed.


The invention provides a method for starting a system and a computer system. The method comprises the following steps: setting processors to be in a manageable mode in advance; S1, communicating a physical link of each processor to a south bridge; S2, establishing a route of each processor for accessing the south bridge, and transmitting the corresponding route of each processor to the processor; S3, transmitting a system starting command to each processor, wherein after each processor receives the system starting command, according to the route for accessing the south bridge, each processor can access the south bridge through the corresponding physical link, obtaining a system starting routine, and executing the system starting routine. By means of the method for starting the system and the computer system, the number of the south bridges can be reduced.


The interaction between surface acoustic waves and high mobility quasi‐two‐dimensional electron systems (2DES) in GaAs/AlGaAs heterojunctions with variable carrier density is investigated experimentally. In specially designed samples the strength of this acoustoelectric interaction can be controlled via the field‐effect induced variation of the carrier density of the 2DES. Since the sensitivity of surface acoustic wave experiments is particularly high at very low conductivities, the proposed technique will be an especially valuable tool for the investigation of 2DES with extremely low sheet carrier densities. We demonstrate that the proper use of a metallic gate electrode does not conflict with the piezoelectric interaction between the mobile carriers confined in the heterostructure and the surface acoustic wave propagating on the piezoelectric substrate.

Abstract Review of: James Hillman, City and soul, Putnam, Connecticut: Spring Publications, Inc., 2006. The second volume of The Uniform Edition of the Writings of James Hillman compiles talks, essays, and lectures over a thirty-year period on the city and the soul of culture. Taken together, these entries outline an aesthetic and imaginal psychology that extends the seminal work of C. G. Jung and develops many of his tenets through a fuller consideration of the mythic, the metaphoric, and the imaginal qualities of soul. Its audience is not just psychologists but any intelligent layperson interested in current cultural phenomena as well as in a further grasp of what crucial place the imagination occupies in the shaping of the city as a psychological place.


M.J. Neeley School of Business, Texas Christian University, USAElectronic commerce (e-commerce) has become a major factor in determining the futuresurvival or success of organizations. The definitions of e-commerce are many and diverse. Inaddition to these, there are varied notions of electronic business (e-business) and collaborativecommerce (c-commerce). Here, we structure the existing five-fold e-commerce taxonomy toaccommodate various e-business and c-commerce perspectives as well. From this, wesynthesize an integrated over-arching definition of e-business. However, the result has alimitation. To overcome it, we advance a knowledge-management view that explicitlyrecognizes e-business as being based on e-knowledge: processes and technologies formanaging knowledge. We contend that the knowledge-oriented perspective of e-commerce/c-commerce/e-business is beneficial in furnishing a common, organized, and unifiedfoundation for understanding and managing electronic organizations in the knowledgee-conomy.

Love story Joan Haste wrote by British author Henry Rider Haggard was introduced to China in the last 19th century,first translated by Yang Zilin and Bao Tianxiao,then by Lin Shu,which produced very big impact.The author compared the two visions in this paper and emphasized that research the version of Yang and Bao help us understanding the tough choices and tortuous heart journey of Chinese intellectuals when facing western culture at the turn of the century.


In the early days of the neurological renaissance that followed the discovery of localized function in the cerebral hemispheres the frontal lobes seemed to select themselves as the seats of the intelligence by a process of exclusion. Once the motor, the sensory, the visual, the auditory, and the olfactory areas had been roughed out upon the, cortex and the tracts coming to and from them plotted with gradually increasing certainty (a task to this day unc'ompleted), it was but natural that speculation should 'be busy with those large areas still remaining which were unresponsive to stimulation and often, but not always, curiously " silent" to destructive or disease processes in man. Those of us who " teethed" in study twenty-five years ago did so on the cortical maps of Flechsig, Elliot Smith, Campbell, Brodmann, and the Vogts, and learned that the grey matter consisted of numerous areas with different developmental histories and with different histological s:ructures. This was true not only of the projection areas but also of the various association areas, and it was demonstrable that the frontal lobes, like other parts, had not one single homogeneous structure, but were subdivisible again into several cantonments, the most posterior of which formed the motor cortex. The work of Ferrier, of Horsley, and of Sherrington in particular, allotted definite functions to the different parts of that latter area, though our knowledge even of the apparently simple motor cortex is not yet complete (see, for example, the revival of interest excited by J. F. Fulton (1932), then by F. M. R. Walshe (1935), and more recently by D. E. Denny-Brown).


Although atmospheric pressure plasma jets (APPJs) have been used for several years in a wide field of applications, there is still a lack of knowledge about physical aspects, namely the phenomenon of spatio-temporally localized luminous effects in the effluent of APPJ, so-called 'plasma bullets'. This paper reports on investigations on the effluent of a low frequency (kilohertz-range) driven APPJ in argon atmosphere. To gain insight into the spatio-temporal structure of the effluent, laser absorption measurements, probing the optical depth of the 4s 3P2–4p 3D3 transition of argon (811.531 nm), which is proportional to the column density of the metastable 4s 3P2 argon atoms, and investigations with an intensified video camera were performed. Simultaneous recordings of the discharge current show that plasma bullets are connected only to a certain current pulse in a series of four pulses of the discharge cycle. A good correlation between the propagation speeds of the plasma bullets (5–20 km s−1) and of the generation zone of metastable argon atoms in the effluent of the APPJ (8–25 km s−1) was found. Both the appearance of plasma bullets and spatio-temporal evolution of the generation zone of metastable atoms can be explained by the effect of a self-propagating ionization front.

In 2001, the National Nuclear Security Administration of the U.S. Department of Energy in conjunction with the national security laboratories (i.e, Los Alamos National Laboratory, Lawrence Livermore National Laboratory and Sandia National Laboratories) initiated development of a process designated Quantification of Margins and Uncertainty (QMU) for the use of risk assessment methodologies in the certification of the reliability and safety of the nation's nuclear weapons stockpile. This presentation discusses and illustrates the conceptual and computational basis of QMU in analyses that use computational models to predict the behavior of complex systems. Topics considered include (1) the role of aleatory and epistemic uncertainty in QMU, (2) the representation of uncertainty with probability, (3) the probabilistic representation of uncertainty in QMU analyses involving only epistemic uncertainty, (4) the probabilistic representation of uncertainty in QMU analyses involving aleatory and epistemic uncertainty, (5) procedures for sampling-based uncertainty and sensitivity analysis, (6) the representation of uncertainty with alternatives to probability such as interval analysis, possibility theory and evidence theory, (7) the representation of uncertainty with alternatives to probability in QMU analyses involving only epistemic uncertainty, and (8) the representation of uncertainty with alternatives to probability in QMU analyses involving aleatory and epistemic uncertainty. Concepts and computational procedures are illustrated with both notional examples and examples from reactor safety and radioactive waste disposal.


A hospital disaster drill is commonly carried out based on the activities assigned beforehand by the occupational description. However, it is difficult for each staff the role is fixing to understand the global image of a disaster correspondence in a hospital disaster when their role is assigned and fixed. We have developed the understandable drill about the whole practice at each hospital in disaster. We keenly realized the necessity of a standard disaster medicine. Therefore we have developed the disaster drill which can be held per hospital. As a goal of a course, each hospital personnel could understand the global image of the disaster, and aimed at the daily course which can master necessary minimum skill to correspond a disaster in each hospital. From the reasons above, we created the course which consisted of a lecture, individual skill training, and a gross training. As essential skill, it starts with (1) management of disaster countermeasures office (2) management of triage post (3) treatment at room (4) support of conveyance between hospitals (5) information control. In order to employ these individual skill booths efficiently we divided attendances into five groups. Five hospitals started from 2008, were carried out 11 times, and about 500 persons took this disaster drill on a course. We expect that cost to bellower, the course to be simpler, and the quality of training will improve by holding this course repeatedly.


Porphyrin-based sensitizers have attracted significant attention due to their excellent performance in dye-sensitized solar cells (DSSCs). Herein, a novel electron donor−π-bridge–electron acceptor (D−π–A) based porphyrin sensitizer having strong electron donating methyl phenanthroimidazole ring and ethynylcarboxyphenyl group at meso- position of porphyrin framework (LG11) was designed and applied as sensitizer in DSSC. To reduce the undesirable loss of open-circuit voltage (VOC) caused by dye aggregation and charge recombination effect, phenyl (LG12) or hexyl phenyl chains (LG13 and LG14) were attached to the phenanthroimidazole moiety. The introduction of a simple thiophene unit between the porphyrin and carboxylic acid anchoring group (LG14) has enabled further extension of the absorption to a longer wavelength. Compared to LG11 and LG12, hexyl phenyl-substituted LG13 and LG14 effectively reduced the dye aggregation and allowed enhancement of VOC to 460 and 650 mV. Both LG13 and LG14 sensitizers exhibit...


Banks play a major role in the moblilisation and allocation of savings in the country. The efficiency with which banks perform these functions is a real gain to the economy. The performance and efficiency of a bank can be evaluated from different angles, such as profitability, interest earned, other incomes generated, interest expended, spread, cost of funds, operating expenses including wage bill, employee productivity, provisioning and return on assets. All these parameters were greatly altered during 1991 to 2004, when a series of reforms in the banking sector were initiated by the Reserve Bank of India, as a part of the economic liberalisation process. This empirical study covering a decade (1994–95 to 2003–04), tries to investigate the impact of reforms on the performance of Scheduled Commercial Banks (SCB), excluding Regional Rural Banks (RRBs).


ABSTRACT A comprehensive long-term study (2006–2010) was undertaken to develop a balanced and integrated nutrient supply system for sunflower-based cropping sequence considering the efficient utilization of residual and cumulative soil nutrient balance along with added fertilizers by the crops grown in rotation. The fertilizer application was done in potato and sunflower while greengram was raised as such on their residual effect. Significant response in yield was observed with 150% of the recommended nitrogen, phosphorus and potassium (NPK) or inclusion of farmyard manure (FYM) with the recommended NPK in the cropping sequence indicating 6.2–7.0% gain in system productivity over the existing recommendations. Each additional unit of P and K nutrition prompted system productivity by 18.9 and 11.0 kg kg−1 of applied nutrient, respectively. Apparent yield decline was observed in K and PK omission plots to the extent of 15.8 and 27.4% in potato, 10.5 and 23.9% in sunflower and 4.2 and 8.3% in greengram, respectively, compared to the recommended fertilization. The superiority of the FYM along with the recommended NPK (potato/sunflower) was evident on the overall profitability and sustainability of the system, highlighted by the significantly higher productivity (7.16 t SFEY ha−1), sustainability yield index (SYI; 0.76), production efficiency (PE; 27.85 kg SFEY ha−1 day−1) and net returns (2520 USD ha−1) with a B:C ratio of 2.91. Apparent change in potassium permanganate (KMnO4)-N was negative in all the treatments while N and P balance was positive with 150% NPK fertilization. Nutrient uptake exceeded the replenishment with 100% NPK application and maintained net negative soil nutrient stock for all the primary nutrients, indicating the need for revalidation of the existing recommendations in the system perspective. Conspicuous improvement in residual soil fertility in terms of maximum buildup of soil organic carbon (14%) and enhancement in soil KMnO4-N (4.2%), Olsen-P (19.4%), ammonium acetate (NH4OAc)-K (5.8%) and dehydrogenase enzyme activity (44.4%) was observed in FYM-treated plots over the initial values. The study suggested that the inclusion of legumes and FYM application with the recommended NPK in potato-sunflower cropping sequence will sustain the system's productivity through the efficient use of nutrients, enhanced microbial activity and improved soil health while combating escalating prices of fertilizers as well as environmental issues in the Indo-Gangetic plains of India and similar environments.


Distributed e-business application platforms such as the web services framework will require sophisticated workload management infrastructures for the routing of client requests to the most appropriate services. This paper introduces a novel and dynamic predictive framework that uses both analytical performance modelling and historical data to extrapolate a request's predicted performance under varying workloads and conditions on different systems. Such a framework can facilitate a routing algorithm in meeting quality of service-based metric requirements. An e-business benchmark is used as a demonstrator to provide an insight into the techniques used in predicting request response times.


Based on the LYQ model,this paper analyzes the dynamic relationship between transportation infrastructure and economic growth in Silk Road Economic Belt. According to the process of economic integration,causality chain is constructed as follows: infrastructure( early investment,road connectivity factor)-transportation( exchange of goods,logistics smooth factor)-trade( economic communication,trade facilitation factor)-economic growth( target,economic integration).With reference to data from 2003 to 2013 in Silk Road Economic Belt,the empirical results show that road connectivity is the principal factor of economic growth,trade facilitation plays an important role and shows a great potential in future,while logistics smooth factor shows a negative contribution to economic growth,which is necessary to adjust its structure.


ABSTRACT Animal vocal behaviour represents a certain meaning, which is the explicit expression of animal emotions, needs and communication. Different from human language, animal vocal behaviour is very abstract, and the learning material of animal vocal behaviour is also more difficult to obtain. It is hard for college students to recognize vocal behaviours of animals accurately. Using virtual reality (VR) to describe them is an innovation in outdoor practice. Zoology teaching can be further enhanced by VR online application. However, current online VR application is mostly restricted as visualization tools, and the application in virtual sound environment is rarely supported. An online VR demonstrator tool was developed by integrating affordable visualization and auralization components. The tool could be published in mainstream web browsers with users' own devices. Sichuan golden monkey (Rhinopithecus roxellana) of Shennongjia Nature Reserve in Hubei province, China was used as the case site to create the virtual environment. A participatory evaluation was performed to test and evaluate the effect of the online VR tool. The result was analysed and discussed on the usability and potential of the VR tool in animal vocal behaviours.


Soil reinforcement techniques making use of passive inclusions such as soil nailing have been steadily growing in Brazil. A research on the influence of geometrical and geotechnical parameters on the stresses and strains developed in nailed excavations has been carried out. The numerical study herein presented made use of FLAC (Fast Lagrangian Analysis of Continua), which is a computational program based on the finite difference method, largely used in geotechnical practice. This paper describes the simulation of nailed soil excavations and presents some relevant considerations regarding the use of FLAC. 1. SOIL NAILING TECHNIQUE Soil nailing is a very efficient technique for reinforcement of natural or excavated soil slopes when stability conditions are considered unsatisfactory. Nailing is done through inclusions of semi-rigid passive elements (nails), which are resistant to tension, shear and bending loads. The reinforcement elements are installed in a horizontal or sub-horizontal direction in the soil mass. Their function is to minimize displacements of the soil mass by adding internal resistant forces. Progressive decompression of soil mass caused by staged excavation generates lateral displacements and therefore induces the internal forces in the nails. Figure 1 illustrates the soil nailing technique, with its successive excavation stages and nail insertion. Working from top to bottom of slope, the soil mass is gradually reinforced during construction. If the material at the excavated region is stable, the nails are immediately installed. If the excavated material appears to be unstable, a thin layer of shotcrete may be applied for avoiding undesirable movements of the soil excavation face. In pre-existing cuts, nailing may also be performed from bottom to top, if this is more convenient. During successive excavations, the slope is subjected to lateral decompression. At end of construction, maximum displacements in both horizontal and vertical directions occur at the top. For soil nailing, horizontal displacements may be up to 0,5%H, where "H" is the total excavation depth (Shen et al., 1981; Juran IV International Workshop on Applications Of Computational Mechanics In Geotechnical Engineering Ouro Preto V. 1 p.143-152. e Elias, 1987). The most important factors controlling these displacements are: construction sequence, excavation depth, nail spacing, nail length and nail inclination angle (Springer et al., 2001; Gerscovich et al., 2002; Lima, 2002). Figure 1 – Construction cycle for nailed soil wall (Clouterre, 1991). There is no standard method for designing soil-nailing structures. Several papers have been reported in the literature emphasizing different failure mechanisms (Shen et al., 1981; Stocker et al., 1979; Juran et al., 1988; Bridle, 1989; Anthoine, 1990). Limit equilibrium is usually considered, neglecting deformations of the reinforced mass and the load distribution in the nails. Numerical modeling is therefore an attractive tool for simulating the sequential construction steps of reinforced excavations and for estimating the nail's loads and the soil's displacements. This paper presents several considerations related to the numerical simulation of nailed soil works using the FLAC computational program. The main focus is to report some aspects to be considered by designers and FLAC users when modeling nailed excavations. 2. BASIC CHARACTERISTIC OF FLAC FLAC (Fast Lagrangian Analysis of Continua) is a 2D computational program based on the finite difference method for simulating the stress-strain behaviour of soil and rock structures. Nine different constitutive models are made available for this simulation. The FLAC's iterative computation cycle is illustrated in Figure 2.

If E and F are saturated formations, we say that E is strongly contained in F if for any solvable group G with E-subgroup, E, and F-subgroup, F, some conjugate of E is contained in F. In this paper, we investigate the problem of finding the formations which strongly contain a fixed saturated formation E. Our main results are restricted to formations, E, such that E = {G|G/F(G) ϵT}, where T is a non-empty formation of solvable groups, and F(G) is the Fitting subgroup of G. If T consists only of the identity, then E=N, the class of nilpotent groups, and for any solvable group, G, the N-subgroups of G are the Carter subgroups of G. We give a characterization of strong containment which depends only on the formations E, and F. From this characterization, we prove: If T is a non-empty formation of solvable groups, E = {G|G/F(G) ϵT}, and E is strongly contained in F, then (1) there is a formation V such that F = {G|G/F(G) ϵV}. (2) If for each prime p, we assume that T does not contain the class, Sp', of all solvable p'-groups, then either E = F, or F contains all solvable groups. This solves the problem for the Carter subgroups. We prove the following result to show that the hypothesis of (2) is not redundant: If R = {G|G/F(G) ϵSr'}, then there are infinitely many formations which strongly contain R.


In this paper we investigated the attitudes of teachers in shaping the culture of schools. In the 21st century, schools face new challenges within increasingly diversified environments. Emphasis is now placed on the need for school leaders and teachers to continually and explicitly create, understand, and nurture school culture so that schools become adept at innovating within the pervasive context of educational diversity and renewal. We examined the culture of two schools in order to gain a better understanding of teacher attitudes of each school's cultural setting. Data were sourced from focus group interviews and observations. The major finding of this research revealed that the culture of schools not only have a significant impact on the conditions of both teaching and learning, but also on the extent to which values, beliefs and norms of connectedness, belonging, and identity are fostered. There is thus a critical need for principals and teachers to focus on the cultural environment prevalent within their schools.


Objective To investigate the role of CD4+ CD25+ regulatory T cells(Treg) in peripheral blood and intestinal endotoxin (ET) in liver injury of rat severe acute pancreatitis (SAP).Methods Sixty male Wistar rats were randomly allocated into sham operation group(SO group) and severe acute pancreatitis group(SAP group).The rats in SAP group recevied the injection of Sodium Taurocholate(NaTc) into their far-end of bile-pancreatic duct and were sacrificed in 3-,6-and 12-hour,serum amylase(AMY) and alanine aminotransferase(ALT) determined by full-automatic biochemistry instrument,limulus reagent method is used to determine ET content in plasma,the proportion of Treg among peripheral lymphocytes was determined by Flow Cytometry(FCM),HE stain is used to observe pathological changes in liver and pancreas,the protein of Foxp3 activity was evaluated by immunohistochemistry staining,and the relationships between these indicators were analyzed using Pearson correlation analysis test.Results Histopathologic examination and the level of ALT revealed the occurrence of pancreatic inflammation and pathological changes of liver in SAP group.The percentage of Treg in SAP groups significantly increased at 3 h(2.26% ±0.32%),6 h(2.36 % ±0.48%)and 12 h(2.80% ±0.35%) comparing to the SO groups(P<0.01) ; plasma ET levels compared with the SO group was statistically significant (P< 0,01 ),and 12 h (0.85 ± 0.11) compared to,3 h (0.74±0.11) and 6 h (0.78-±-0.07) was no significant difference (P>0.05).The expression of Foxp3 protein on the livers were upregulated markedly.Pearson correlation analysis teat showed that quantities of Treg were positively proportional to the levels of ET(r=0.89,P<0.01) after liver injury of SAP.Conclusions SAP may lead to liver injury and the high plasma levels of ET and Treg in peripheral blood may play an important role in liver injury of SAP.

Cognitive load measurement is important when designing adaptive interfaces that optimize the performance of users working on high mental load tasks. Recent research on automatic speech-based measurement system indicates that cognitive load information is more prominent in the frequency region below 1 kHz. This study investigates the effects of cognitive load on glottal parameters (open quotient, normalized amplitude quotient and speed quotient), and proposes a system employing these parameters as features for cognitive load classification. Analysis of the glottal parameter distributions suggests that an increase in cognitive load can be related to a more creaky voice quality. Additionally, three-class classification results show that score-level fusion of systems based on the glottal features and baseline features (MFCCs, pitch, intensity and shifted delta cepstra) improves the baseline accuracy from 79% to 84%.


Abstract : Modern Times' bring change in all areas of life. Even the rate of change has changed, and is still changing to increase it's enormous speed even more. Newer and more challenging questions face the military analysts everyday putting a question mark at the end of their last answer. Recently, the question of how to structure a robust air force to meet the requirements of competing, uncertain future scenarios has been keeping them busy. The new world order does not tolerate only being able to respond to a single scenario anymore, which once was considered a hard problem . Who knows what comes next? In this thesis, we propose a robust optimization methodology to provide an answer to the multi-scenario optimization problem. The methodology employs a meta-heuristic, Scatter Search, to guide the search of the multi-scenario solution space obtained by the evaluations of CFAM, the model currently used to respond to single theater scenario objectives.

This study was conducted to evaluate reproductive performance of Barki ewes subjected to three estrus synchronization programs in field conditions during breeding season. For this purpose, 36 cycling ewes were divided into 4 groups according to the program assigned: Group SeCG (n=10): received intravaginal progesterone sponge (40 mg Fluorogestone acetate, Chrono-gest®, Intervet International) for 7 days, at time of sponge removal, each ewe received i.m injection of 500 IU eCG (Folligon®, Intervet International); Group PG-PG (n=10): received double injections of 250μg Cloprostenol (PGF2α analogue, Estrumate®, Intervet International) 11 days apart; Group GPG (n=6): received 4μg Buserelin by i.m injection on day 0 (GnRH analogue- Receptal®, Intervet International), on day 5 animals received 250μg Cloprostenol followed by 4μg Buserelin by i.m injection on day 7; Group C (n=10): served as control group that did not receive any treatment. Results showed that estrus induction rate was significantly high in SeCG group that was recorded at 100% (P<0.05), while it was 90%, 60%, and 50% for PG-PG, C and GPG respectively. Estrus synchrony was more uniform in SeCG group as 70% of ewes exhibited estrus around 24-36 hrs from end of treatment. There was no significant difference among groups in pregnancy and lambing rate (p>0.05). Pregnancy rates were 100%, 90%, 88.9%, and 83.3% for GPG, SeCG, PG-PG, and C group respectively. Conclusion , from results we conclude that intravaginal progesterone sponge for 7 days+500IU eCG at sponge removal is convenient for estrus synchronization of ewes raised in field conditions during breeding season. Moreover, reproductive and fertility parameters recorded in the current study are acceptable and within values reported previously in farm conditions.


The necessity of determining the sex in the bird's egg by non-invasive methods before incubation and during the incubation period is shown. The use of non-destructive methods for assessing sexual dimorphism in practice will significantly reduce the cost of producing eggs and poultry meat. The introduction of such methods will reduce the moral problems associated with the physical destruction of hatched chickens, depending on the egg or broiler direction of the poultry farm profile. The main methods and technical means for determining sexual dimorphism, used in world practice, are considered, the main disadvantage of which is the complexity of implementation and the associated high cost of acquiring such tools. Analysis of current world trends in the determination of sexual dimorphism of embryos in the poultry egg was carried out. Less costly methods of estimating their sex before and during incubation were identified. The main noninvasive methods for assessing the sexual dimorphism of the egg embryo are analyzed and the advantages and disadvantages of these methods are shown. The scientific novelty of the research lies in the fact that for the first time it was proposed to use all shape parameters, including egg asymmetries in three spatial coordinates, determined by computer vision methods, when assessing sexual dimorphism. An experimental colorimetric apparatus for assessing the sexual dimorphism of egg embryos before and during the incubation process based on computer vision was proposed. The use of an experimental setup in research will allow evaluating the effectiveness of at least 3 methods for determining the sexual dimorphism of chicken eggs in terms of parameters: spatial asymmetry of the egg, structural changes in the development of the embryo and its heart rate.
