This article proposes the implementation of a Maximum Power Point Tracking (MPPT) controller for a Doubly Fed Induction Generator (DFIG) wind turbine using a Luenberger observer. The implementation is based on the Direct Speed Control (DSC) strategy including a state observer which operates according to the reference current used for the power converter control. Moreover, this controller allows to regulate the Low Shaft Speed (LSS) for a better MPPT within the operating zone before the pitch controller command is activated, improving the power extraction manifested in the Power Coefficient (Cp) value. This control strategy has been validated in a 9 MW DFIG wind turbine system by means of the simulation in Matlab-Simulink and the Fatigue, Aerodynamic, Structure and Turbulence (FAST) software. The performance of the technique has been evaluated under normal operating conditions and the incorporation of 10% white noise for testing the robustness. Implementing the state observer, the wind turbine system responds more sensitively to the presence of disturbances in the mechanical system. The technique allows to increase the power extraction.

When the sugarcane is delivered to the factory it goes through a series of analysis before going to the production. The quality (amount of sucrose and purity) of the raw material is the key for the monetary evaluation. The ash content in the sugarcane fibers remaining after the liquid extraction is analyzed to determine mineral impurities.


We investigate the relation of fast flows at the inner edge of the plasma sheet to the onset of auroral expansion. Recent work suggests that nearly all expansions are an instability triggered by an auroral streamer from far out in the magnetotail. We investigate an 8‐hr interval of activity on 14 March 2008 using ground magnetometer and all‐sky camera data to determine the onset times of six substorm expansions. We compare these times with Time History of Events and Macroscale Interactions during Substorms observations of plasma flow and magnetic field. We show that every expansion followed the arrival of a fast flow and dipolarization event at the inner edge of the plasma sheet. To relate the aurora to flows, we develop procedures for removing fixed lights, the moving Moon and its reflection, and contamination due to scattered moonlight. We scan movies of enhanced images for auroral streamers. Three onsets were tentatively associated with streamers. For two, the apparent source was very close to the growth phase arc mapping close to Earth. For one, an onset occurred in the recovery phase of an earlier substorm after a double oval had formed. For this one, the end of an N‐S streamer stopped about 2° north of the breakup arc. For the remaining three expansions, no streamers were associated with the onsets. Most substorms exhibit N‐S streamers in the recovery phase. These usually cannot be associated with fast flows. Either fast flows in the growth phase do not produce streamers or they make streamers that require significant image enhancement.

Background and Objectives: The incidence of atrial fibrillation (AF) is increased in heart failure (HF). Two major mechanisms of ventricular arrhythmia in HF are reentry mechanism due to tissue fibrosis and triggered activity due to an altered calcium-handling process. Unlike studies on ventricular arrhythmogenesis, only few studies investigated the relationship between changes in the calcium-handling process in atrial tissue and their relationship with atrial arrhythmogenesis in HF. Materials and Methods: HF was induced by myocardial infarction, and the rats were fed a normal sodium diet for 10 weeks and administered isoproterenol (30 μg/[kg∙h]) for the last 2 weeks of the experiment. Echocardiography and AF induction studies were conducted. In addition, mRNA and protein expressions of sarcoplasmic reticulum Ca 2+ -ATPase (SERCA), phospholamban (PLB), ryanodine receptor 2 (RyR2), and sodium calcium exchanger (NCX) were studied. Results: In the HF group, the ejection fractions were significantly decreased. AF duration (12.4±7.9 sec sham and 441.7±12.4 sec HF) and inducibility (8.0%±3.3% sham and 48.5%±10.6% HF) were significantly increased relative to the sham group. Atrial fibrosis tissue amounts were significantly increased in HF (0.20%±0.02% sham and 3.41%±0.45% HF). Atrial SERCA, PLB, RyR2 protein, and mRNA expressions were significantly decreased in HF, while the NCX protein expression was significantly increased in the HF group. The protein PLB/SERCA ratio was significantly increased by about 33% in the HF group. Conclusion: Changes in the protein and mRNA levels of calciumhandling proteins and increase in the degree of atrial fibrosis are important contributing factors of AF in severe HF.


observe that for many there will be very little in this book that is 'new'-neither for biblical scholars nor for students of literature; nor for those of us-all of us, in a way-who must because of our vocation be both. What is 'new' is the final product, the whole book, in its synoptic power and lucidity. He uses what we already have and know-the great mass of historical-critical scholarship on the Bible and the great mass of literary scholarship on the nature of literature-as a means to recover (what that scholarship too often obscures): the Bible, including and especially its final arrived, edited, crafted, us-interrogating shape. The Great Code is an example of the 'genuine higher criticism' (xvii) for which it asks. For a number of reasons it will probably be accorded many adjectives, including some meant pejoratively-mystical, esoteric, eccentric, banal, Blakean, etc. There will be a grain of truth to them all. There is no doubt that Frye's seminal mind sometimes belabours the obvious and asserts the unobvious. In this book it must. But there is also no doubt that Frye sees the Bible that is there to the Western observer, the Bible that must be seen. If some literalist object, as one once did to Blake, that that is not what she sees, then Blake's reply is apropos also here: '0 madam, but don't you wish you could?'


SUMMARY Three mathematical models for the joint action of two drugs are considered, each model being a special case of a more general model for the joint action of drugs showing complete positive correlation of tolerances. The models are likely to be of most use in the analysis of responses to drugs acting similarly. The maximum likelihood procedures for fitting the models to data, and for calculating errors, are discussed. In general these procedures consist of iterative operations whereby corrections to initial estimates of the parameters are calculated; the computations can be done with a good desk calculating machine. Numerical examples are given. In the preceding paper of this series, Hewlett and Plackett [1959] constructed very general models for the quantal responses to mixtures of drugs operating non-interactively 'on biological material, giving fully the biological basis for the models. The models take into account the degree of similarity between the biological effects of the two drugs, the relations between the doses of the drugs and the amounts acting, and the bivariate distribution of tolerances of the individual organisms to the two drugs. The fitting of these models in general would be complex, requiring an electronic computer, but there are certain useful special cases for which a good desk calculating machine can suffice. It is these special cases that we are concerned with here. They are likely to be useful mainly in the analysis of data for responses to drugs acting similarly. All the models measure quantal response in terms of the normal equivalent deviation (N.E.D.), defined as follows. If p is the proportion of organisms responding to a drug and 4(x) is standard normal cumulative distribution function, then the N.E.D. corresponding to p is


The author expressed formally a new opinion about the occurrence of slip and rupture from the standpoint of non-elastic energy dissipation. This paper treats the from and occurrence of slip and rupture which occurred under a pure axial tension, from the standpoint of the author's new idea. A uniform elongation is generally stepped by a local deformation ( a deformation of a local portion). The relation between the uniform deformation and the local deformation is, as it were, the relation between the stationary state and the transition state as considered in physics. The transition state corresponds to an occurrence of a slip band, and the stationary state corresponds to a state of a uniform elongation. Namely, the so-called lawer yield point corresponds to the value of P cosθ, P being the load just before lowering, θ being the inclination of the slip band.


Penguins are often considered to be as ecologically and behaviourally homogenous as their morphology. Their structural morphology and associated physiological adaptations are governed by the demands of operating as flightless, subsurface marine predators. However, within the very strict constraints of this life-form, penguins in fact show considerable ecological and behavioural heterogeneity. Some of this undoubtedly relates to the range of latitudes and biotopes in which penguins breed, ranging from Antarctic ice-shelves, through cool temperate sub-Antarctic islands to warm temperate, even subtropical, coasts, and to the equator itself. Nevertheless, even allowing for this, in some of their potentially more fundamental ecological and demographic attributes, penguins show a surprising degree of interspecies variation. This variation contains a number of apparent paradoxes.


stock market highlights the need for investors to reexamine the potential b e n e f i t s of portfolio diversification. Real estate investment trusts (REITs) have the potential to provide competitive expected returns even in a recessionary environment and display low correlation relative to domestic, international, and technology stock and bond markets. As a result, investors who include REITs in a mixed-asset portfolio may substantially improve their portfolio's REITs as an Alternative Investment in Volatile Financial Markets


A new white light emitting diode, the photon recycling semiconductor light emitting diode (PRS-LED) is demonstrated. The device consists of a GaInN/GaN LED emitting in the blue spectral range and an AlGaInP photon recycling semiconductor emitting at the complementary color. The PRS-LED thus has two emission lines, one in the blue and one in the amber wavelength range. The theoretical luminous efficiency of the PRS-LED exceeds 300 lm/W, higher than the efficiency of phosphor-based white LEDs.

This paper presents an experimental procedure for the identification of parameters of an octorotor unmanned aerial vehicle (UAV), as well as the obtained model validation via control. The octorotor UAV is a highly nonlinear, multivariable and strongly coupled system. The mathematical model of used UAV includes rigid body dynamics, the Gyroscopic effect and motor dynamics. In order to estimate eleven unknown parameters, the experiments are specially prepared and conducted on the custom made apparatus. Therefore, on basis of obtained measurements, some modifications of the octorotor model are made.

However, because of the high cost of Ge enriched in 76Ge special procedures were required to maximize the yield of detector mass and to minimize exposure to cosmic rays. These procedures include careful accounting for the material; shielding it to reduce cosmogenic generation of radioactive isotopes; and development of special reprocessing techniques for contaminated solid germanium, shavings, grindings, acid etchant and cutting fluids from detector fabrication. Processing procedures were developed that resulted in a total yield in detector mass of 70%. However, none of the acid-etch solution and only 50% of the cutting fluids from detector fabrication were reprocessed. Had they been processed, the projections for the recovery yield would be between 80% and 85%. Maximizing yield is critical to justify a possible future ton-scale experiment. A process for recovery of germanium from the acid-etch solution was developed with yield of about 90%. All material was shielded or stored underground whenever possible to minimize the formation of 68Ge by cosmic rays, which contributes background in the double-beta decay region of interest and cannot be removed by zone refinement and crystal growth. Formation of 68Ge was reduced by a significant factor over that in natural abundance detectors not protected from cosmic rays. © 2017 The Authors. Published by Elsevier B.V.

I talked to a couple of instructors this past month. John Ross and Dan Smith who are both instructors in the St. Louis area told me that they have their classes book solid. Dan Smith (www.concealedcarryfirearms.com) who operates his classes out of Top Gun Shooting Sports near Arnold, MO has at least 20 students per class, the most the room will hold. John Ross (www.john-ross.net) who runs his classes out of the VFW hall in Brentwood, MO fits about 40 people in his class in a lecture hall type setting. Both say the demand for people getting their concealed carry permits is at an all time high.


The optical head is an important and major component for optical disk drives. For the read/write optical drives, expected to be generally available soon, the optical heads using conventional design often include some bulky optical lenses and prisms. The use of HOEs can greatly reduce the component counts, size, and weight of the optical head. We expect that these will improve the performance. We describe an optical head design using HOEs. The design uses two spherical plano-convex lenses and two HOEs. The two HOEs correct the spherical aberrations of the lenses, compensate wavelength shifts up to ±5 nm, and change the elliptical beam to a circular shape. Experiments have been performed to confirm the design concept. Techniques for making the HOEs and experimental results are described.


In Nilgiris, the Cooperative Factories had a positive impact in helping the small tea growers, particularly those with very smallholdings. At the same time, considering their financial and technological constraints, small-scale growers have expanded their holdings and their productivity over the years. It indicates that the smallholders were more enterprising in growing production than the vast estates whose production got stagnated. In areas where there are no cooperatives, the cooperative factories have ensured not only equal prices for their members but also other tea leaf suppliers. In these areas, the Cooperative Tea Factories ensured to pay the market prices to their members. This article is a summary of the studies conducted in India with particular focus on the influence of the restriction of small tea growers, the factors influencing tea growers to engage in tea cultivation, and the environmental effects of using chemical fertilisers and pesticides in the Small Tea Gardens.


The study of prey consumed by different species has been useful for the understanding of the relationships among species. The use of stables isotopes in studies of diet offers advantages over other methods. The objective of this study was to determine, using stable isotopes, whether Chilabothrus inornatus that actively forage in caves have a different prey spectrum than snakes that forage in the forest. Tissue samples from the tail of free-ranging and cave-associated snakes were collected. Mean isotope values were not statistically different between the free-ranging and cave-associated C. inornatus. Free-ranging snakes showed more isotopic variance in δ C suggesting different types of prey being consumed at different localities. Free-ranging and caveassociated C. inornatus acquired most of their energy from rodents (rat and mice). These explorations of diet using stable isotopes have provided an initial baseline for the development of new research incorporating this technique. Future research might focus on the seasonality of prey and the response of C. inornatus to it.

Bone remodeling is a function of the stress applied to the bone. In the case of the glenohumeral (GH) joint, an initial external rotation of the humerus (retrotorsion) at birth derotates with age, as normal processes are anterior to the shoulder, such that the humerus is comparatively internally rotated (anterotorsion) by adulthood1,2. However, in the case of certain athletes, such as pitchers, an overhead throwing motion has been shown to resist the anterotorsion process by means of strong, external torque around the humeral growth plate3,4.Copyright © 2013 by ASME


The presence of a foreign body implant enables skin derived bacteria to become pathogenic. After adhesion to the implant surface, CNS produce an extracellular mucoid biofilm that embeds the growing cells. This is acting as a barrier that prevents penetration of antibiotics. The key to effective prophylaxis of infection seems to be the prevention of initial bacterial adhesion by antimicrobial device impregnation or coating. In the present study efficacy of a technique of incorporating an antibiotic into a silicon polymer in preventing surface colonization has been evaluated by the use of scanning electron microscopy (SEM) and culture methods. The study was conducted using rifampicin which was found to be effective by the antibiotic sensitivity test done previously under chapter-5. The most predominant CNS species S. epidermidis was selected for the study.


The emergence of antibiotic-resistant strains of bacteria has become big news, not just in the professional literature but in the popular press.

This research has investigated the effect of the dimensions of organisational trust (OT) on the tacit knowledge transfer (TKT) by the willingness to share (W2S) and the willingness to use (W2U) the tacit knowledge (TK) of public library employees. In terms of nature, the present study is an applied research that, using a descriptive-correlation method. The study sample includes 140 employees of public libraries in Chaharmahal Bakhtiari province, the OT questionnaire Nguyen (2005) and the tacit knowledge sharing (KS) questionnaire Saparito(2000) were used. As well as descriptive statistics, the Kolmogorov-Smirnov test, Pearson correlation coefficient, and regression test were used to analyse the data. There is a positive and significant relationship between calculus-based trust(CBT) and employees' willingness to TKT. There is a positive and significant relationship between knowledge-based trust (KBT) and employees' W2S and apply TKT. There is a positive and significant correlation between identity-based trust (IBT) and employees' W2S and apply TK. The relationship between IBT and the desire to KS is stronger than the relationship between CBT and KBT. Therefore, IBT has a stronger effect than KBT and CBT on the tendency to KS. Employees in the IBT stage are more inclined to share and use TK than employees in the CBT and KBT stage. The TKT is an interactive process formed by the trust between the parties. The results of the current study show that OT has a positive and significant effect on the TKT of public library staff.


Ionic solids and melts are compounds in which the interactions are dominated by electrostatic effects. However, the polarization of the ions also plays an important role in many respects as has been clarified in recent years thanks to the development of realistic polarizable interaction potentials. After detailing these models, we illustrate the importance of polarization effects on a series of examples concerning the structural properties, such as the stabilization of particular crystal structures or the formation of highly-coordinated multivalent ions in the melts, as well as the dynamic properties such as the diffusion of ionic species. The effects on the structure of molten salt interfaces (with vacuum and electrified metal) is also described. Although most of the results described here concern inorganic compounds (molten fluorides and chlorides, ionic oxides...), the particular case of the room-temperature ionic liquids, a special class of molten salts in which at least one species is organic, will also be briefly discussed to indicate how the ideas gained from the study of 'simple' molten salts are being transferred to these more complex systems.


As known as opinion mining, sentiment analysis is a work by using the "natural language processing" method to find out the author's attitude, emotion or evaluation on certain topics. This paper using a dataset by Mass et al from its original Stanford AI Repository, and a commonly pre-processing method——word embedding, and establish a deep learning model for sentiment analysis. From the perspective of data analysis, learn about the movie preferences and cultural characteristics of audiences from domestic and foreign. In the experiment, we compared the performance of RNN, LSTM and GRU in natural language processing, and improve the efficiency and accuracy of sentiment analysis by a fusion model which integrating recurrent neural networks variant at the output of convolutional neural network.


Juvenile delinquency is a subject of interest both internationally and nationally, due to the high frequency of this negative social phenomenon, as well as finding the most adequate ways to combat it. Juvenile delinquency arose as a consequence of illicit, unacceptable, deviant, antisocial behavior of adolescents. Juvenile delinquency is a separate form of crime, because it includes all juvenile offenders, regardless of whether the crime is property, violence or traffic crime. This scientific paper will refer, first of all, to the conceptual definition of juvenile delinquency, the factors that influence its occurrence, the legislative framework, as well as the position of juveniles in criminal proceedings.

Methods: Data were collected by ques- tionnaire in 1987-88 in a five year follow up study of a random sample (n=3608) of men and women aged 35, 45, 55, and 65 years, and living in the County of Copenhagen, Denmark. A total of 2987 participated in the study. Ad-ditional information on non-participation and the method of data collection have been reported elsewhere.4 Both subjectively perceived and more objective aspects of social network were measured by six variables: (1) contact frequency with family or (2) with friends, neigh-bours, and relatives; (3) involvement in community activities; (4) marital status; (5) emotional support reflecting the opportunity for talking to intimate relatives and friends about personal matters; and (6) social support describing the person's satisfaction with access to social support when feeling lonely.


Today, agriculture remains the most distorted sector of the world economy. Therefore, agricultural liberalization in the Doha negotiations is rightly the top priority. But the public-policy discourse on the subject remains fogged by a number of fallacies. These fallacies probably originated with the leadership of the World Bank but have now been embraced by the IMF, OECD, Oxfam and the leading academic critics of globalization. The paper identifies six fallacies and offers evidence and analysis to debunk them: (1) Agricultural border protection and subsidies are largely a developedcountry phenomenon. (2) Developed-country agricultural subsidies and protection hurt the poorest developing countries most. (3) Developed-country subsidies and protection hurt the poor, rural households in the poorest countries. (4) Developed-country agricultural protection and subsidies constitute the principal barrier to the development of the poorest developing countries. (5) Agricultural protection reflects double standard and hypocrisy on the part of the developed countries. (6) What the donor countries give with one hand (aid), they take away with the other (farm subsidies). ∗ Professor of Economics and Bhagwati Professor of Indian Political Economy, Columbia University, School of International and Public Affairs, New York, NY 10027.

After China joins the WTO, the tendency of smuggling offence will not be decreasing because of the reduction of tariff rate and the loosening of controlling measures to import. On the contrary,smuggling offence will present some new characteristics on such aspects as the object , behavioral methods, scale and techniques ,etc. Aiming at the forming causes of these new characteristics, we must take synthetic measures to reduce and control the occurrence of smuggling offence radically.


Individuals with Junctional Epidermolysis Bullosa (JEB), a rare genetic skin disease characterised by loss of function mutations in the Laminin332 (Lam332), do not survive beyond their first birthday. Here we report that loss of Lam332 leads to absence of cholesterol lipid from the epidermis in vitro and in vivo. Stable knockdown of Lam332 chains (LAMA3, LAMB3 and LAMC2) was established using shRNA and were used to develop 3D skin equivalents. Changes in lipid synthesis were assessed by western blot analysis and immunohistochemistry. Findings were confirmed in an inducible mouse model of Lamα3 (Lama3flox/flox/K14CreERT) and in anonymized, archival human tissue: JEB skin and normal age-matched controls. Further lipid analysis was explored using lipidomics in 3D skin equivalents and mouse tissue. Cholesterol biosynthesis genes were increased with loss of Lam332 in vitro, however a decrease in nile red lipid staining was observed in Lamα3 mouse (n = 6) and in JEB patient skin (n = 7). Further changes to the epidermal lipid profile with loss of Lam332 was confirmed with lipidomic analysis of Lamα3 mouse epidermis and Lam332 skin equivalents. Cholesterol transport within Lam332 KD keratinocytes was revealed to be disrupted, which in keratinocytes is dependent on the actomyosin network, which was reversed with recombinant human Lam332. In conclusion these findings suggest a role for Lam332 in lipid metabolism in the skin and a broader role in epidermal homeostasis and barrier formation. Restoration of cholesterol transport in JEB patients offers the potential to improve the skin barrier and survival.


For conditions of the moderate and increased moistening of river basins it is shown that the treelike structure of water channels network causes gradual or spasmodic increase of the main river water runoff. There are violations of this regularity on sites of river and estuary branching. Processes of drain concentration are interrupted owing to channel bifurcation on rather short sites of river valleys. They become irreversible on sites of branched estuaries. Branching is characteristic for 17-35% of rivers extent of Northern Eurasia. On certain large rivers this morphody-namic type of the channel is up to 70% of their length. Research of water channels structure on branched sites of rivers is made. For this purpose information on 120 branched sites of 40 rivers of Russia, and on branching of river mouths in the South and the North of Russia is generalized. Possibility of formalization of water streams structure on sites of braided channels is studied. The concept of conventional orders for determination of the relative sizes of branches in channel and estuary forks is offered. The justification of determination method of branches conventional orders depending on their water content is given. It is established that information on the size of branchings conventional orders creates preconditions for their comparison by relative sizes, for determination of traction load runoff by parameters of ridges, for assessment of washout rate of concave banks of bends, for solutions of other applied and theoretical hydrologi-cal tasks. On this basis the criterion of similarity of dispersion conditions of river runoff on waterways on sites of braided channels is received and its ranges of change corresponding to weak, moderate, strong and exclusively strong variants of development of this process are specified. Processing of natural information showed that the size of similarity criterion changes in the range from 0.05 to 0.8 and depends on type of branching. More than 75% of single forks are characterized by weak dispersal of water runoff, complex single forks and systems of connected forks are distinguished by moderate dispersal of drain. Intense dispersal of water runoff is characteristic for inundated-channel forks of semi-mountain rivers, and also for parallel and branch forks of big plain streams. Research of channel branching functions leads to studying of transformation regularities making a river runoff on multichannel sites of rivers, a condition of marginal effect features studying in mouth areas of the rivers. The concept of conventional orders now is the only opportunity for the description of topological properties of water currents network on sites of channel and estuary branching, and the analysis of large-scale effects of material streams change within their limits.


Histones are important proteins that interact with the DNA double helix to form nucleosome. Two putative histone genes, GjH2A-1 and GjH2A-2 were isolated from a red alga Griffithsia japonica. The putative open reading frame of GjH2A-1 and GjH2A-2 shared high similarity with the previously reported amino acid sequences of histone H2As. They have a motif consisting of seven amino acids A-G-L-Q-F-P-V, which matches the histone H2A motif [AC]-G-L-x-F-P-V. Phylogenetic trees were constructed from amino acid sequences of 38 histone H2As. The histone H2As were divided into two groups: major H2As and H2A.F/Z variants. The major histone H2A group consisted of animals, fungi, plants + green algae, and red algae H2A subgroups. The animal histone H2A subgroup was divided into vertebrates, echinoderms, nematodes, insects, and segmented worms H2As. The putative red algal histone genes, GjH2A-1 and GjH2A-2, constituted an independent lineage. This is the first report on red algal histone genes.


We differentiate the effects of passive institutional investors on firms' innovation activities and innovation strategies, and explore underlying economic channels. Relying on plausibly exogenous variation in passive institutional ownership generated by Russell 1000/2000 index reconstitutions, we find that, with larger passive institutional ownership, while firms' countable innovation activities increase, they shift their innovation strategies by focusing more on exploitation of existing knowledge instead of exploring new technology. Enhanced monitoring by passive institutional investors through active votes could explain their positive effects on firms' innovation activities. Short-termism on the part of passive institutional investors appears the underlying force that drives firms' shift to incremental innovation. Our paper uncovers a subtle relation between institutional investors and innovation, which is largely ignored by earlier studies.


ASTROSAT is a scientific mission aimed at providing space based multi-wavelength observatory in the frontier areas of astronomy. It carries scientific instruments sensitive over a wide spectrum of wavelengths covering Visible, Ultra Violet, Soft X-rays and Hard X-rays over an energy band of 2–100keV. It accommodates five payloads to perform the task. Scanning Sky monitor (SSM) is one of the payloads designed to measure the soft X-rays over a band of 2–10keV for transient events. Electrical integration of SSM payload poses huge challenges in the form of design and implementation of electrical distribution system for rotating mechanism, grounding of electronics packages on Carbon Fibre Reinforced Plastic (CFRP) platform, problems faced during the testing in dis-assembled mode and measures taken to overcome the same. This paper discusses the above mentioned aspects from the perspective of electrical integration and testing.


This paper examines over a two hundred year period the changing context of ritual performance and the use of tree symbolism within the patron saint's cult of a small southern Italian village. Set against a background of rapid, sometimes turbulent, social and economic change—the loss of communal rights, the switch from transhumance to an arable economy, the transformation of town-country relations, mass migration, the emergence of an increasingly peasantised economy—it describes the different ways in which key elements in the festa complex provide a focus for local anti-clericalism, and both a language and symbolism of peasant protest. It also explores the relationship between this protest tradition and local understandings of history and the meaning of a 'tree-centred' civic ceremonial.


Background: In this era of globalization one of the growing industries is the construction industry and there are various occupational problems faced by the workers especially in Asian countries mostly in India; the problems are related to both physical and mental health. All the construction sites generate high concentration of dust particles from cement, silica, asbestos, concrete, wood, stand and stand that causes respiratory problems in the workers. PEFR is the maximum air that is generated after forceful expiration, after full lung inspiration. So if there is any accumulation of dust particles the PEFR decreases as the elasticity of lungs to recoil is distrusted due to the lodged particles.
Material and Method: A descriptive observation study was carried out on 50 building construction workers. The purpose of the study was explained and informed consent was taken. The PEFR was measured using peak expiratory flow meter. The data was analyzed using standard statistical software.
Result: The procedure of using peak flow meter that was carried out for 3 times and the highest value from the three was considered as peak flow rate, using statistical method mean and standard deviation were calculated. The mean of Peak Expiratory Flow Rate is 321.1 L/min.
Conclusion: This study concluded that the peak expiratory flow rate is reduced in building construction workers those who are working for than 2 years on the construction sites.

Key words: construction workers, occupation diseases, PEFR, peak expiratory flow meter.

This paper presents the results of full-scale experiments in a realistic building to evaluate natural convective heat and mass transfer through doorway-like apertures under small temperature differentials. The zone-to-zone temperature differences were nominally between 1°C and 2.5°C. Heat transfer correlations, coefficient of discharge, and thermal stratification are reported for air (Pr = 0.71), an enclosure aspect ratio of 0.26, aperture height relative to the enclosure height in the range of 0.75 to 1, and aperture width relative to the enclosure width in the range 0.29 to 0.79. In general, the results extends the validity of previous theoretical and experimental work in the literature to large doorway-like apertures and small temperature differentials across the aperture typical of residential building conditions.


In this work, antimicrobial agar based nanocomposite films containing silver nanoparticles were prepared. For the synthesis, a masterbatch of in situ stabilized silver nanoparticles produced in agar solution was used. The incorporation of silver nanoparticles improved the mechanical and water vapor barrier resistance of films, in comparison to the neat agar film without silver. Agar/Ag films showed high antimicrobial activity against Staphylococcus aureus, Escherichia coli and Candida albicans. The migration of silver nanoparticles from the agar films, assessed by food contact tests, was less than 0.05 mg/g which is under the legal limits. These results indicated that the agar films incorporated with silver nanoparticles have potential to be used as packaging material.


The granin family of neurotransmitter‐like molecules, neuropeptides, are proteolytically processed into functional peptides, also known as proteoforms. This family contains secretogranin VII (VGF), which was highlighted by AMP‐AD as the most nominated potential therapeutic target for Alzheimer's disease (AD) due to its levels being decreased in CSF samples and brain sections from patients with AD. Full‐length granins and their proteoforms are involved in diverse neuronal and synaptic functions, but their physiological processing pathways, contribution to dementia pathogenesis and potential use as a biomarker of dementia remain understudied. This project investigated the proteolytic processing of granins in silico and in vitro to improve our understanding of whether specific granin proteoforms represent potential therapeutic targets and biomarkers of dementia.


The reconstruction of the history of evolutionary genome-wide events among a set of related organisms is of great biological interest. A simplified model that captures only content modifying operations was introduced recently. It allows the small phylogeny problem to be formulated as an alignment problem. In this work we present a branch-and-cut algorithm for this so-called duplication-loss alignment problem. Our method clearly outperforms the existing ILP based method by several orders of magnitude. We define classes of valid inequalities and provide algorithms to separate them efficiently and prove the NP-hardness of the duplication-loss alignment problem.


Integrin‐linked kinase (ILK) is a multi‐domain protein kinase that binds to the cytoplasmic tail of beta integrins and signals to pathways that regulate cell growth and differentiation. We modulated ILK expression in tracheal muscle tissues and evaluated the effect on smooth muscle myosin heavy chain (SmMHC) expression. ILK antisense was used to depress ILK protein expression, and FLAG‐ILK was expressed in smooth muscle tissues to increase ILK protein expression. ILK antisense treatment for 24 hrs caused the depletion of ILK protein by 30–40% and stimulated a two‐fold increase in the expression of SmMHC protein. Real time RT‐PCR of tissue extracts demonstrated a significant increase in SmMHC mRNA. Transfection with ILK‐FLAG plasmids induced a 40–50% increase in ILK protein expression, inhibited SmMHC expression by 30–40% and decreased SmMHC mRNA. Immunofluorescence analysis and cell fractionation were used to evaluate the effect of modifications in ILK expression in the tissues on the cellular localization of the transcriptional regulator, SRF. More SRF fluorescence was observed in the nucleus of cells dissociated from ILK‐depleted tissues relative to untreated tissues and more SRF was detected in nuclear extracts from ILK‐depleted tissues. A ChIP assay confirmed increased binding of SRF to the SmMHC promoter in extracts from ILK‐depleted tissues relative to undepleted tissues. Our results suggest that ILK is a negative modulator of SmMHC expression in airway smooth muscle, and that ILK decreases the amount of SRF that localizes to the nucleus and reduces SRF binding to the SmMHC promoter.

Abstract 5035 Rationale: Recent studies demonstrate superiority of bortezomib-containing regimens over standard therapy at improving response rates and durability of responses in patients with multiple myeloma (MM). However, limited data exist for the feasibility of delivering bortezomib-containing regimens to patients with MM over the age of 70 years. We therefore conducted a retrospective review of administration of bortezomib in combination with pulsed Dexamethasone (Bort-Dex) in elderly patients to determine the feasibility and toxicity of delivery. Methods: Patients >70 years with MM who had received at least one prior line of treatment but had not been previously exposed to bortezomib, were assessed for their predicted tolerance to Bort-Dex: bortezomib 1.3mg/m 2 IV on days 1, 4, 8 and 11 (standard) on a 21 day-cycle or on days 1, 8, 15 and 22 (modified) on a 35 day cycle, in association with dexamethasone 20mg on the day of and day after bortezomib. Treatment was discontinued at maximal disease response, if refractory disease or if treatment-related toxicity precluded further cycles. A control cohort comprised patients Results: 19 elderly patients with MM (IgG n=14; IgA n=2; light chain disease n=3) and a median age of 80 yrs (range 74, 90) were compared with 19 MM patients (IgG n=11; IgA n=3; light chain disease n=5) aged Conclusions: Reductions in the intensity and frequency of dosing are often required in order to deliver Bort-Dex to elderly patients, though with comparable response rates to younger patient populations. Through drug delivery modifications, Bort-Dex therapy can be delivered with an acceptable adverse event profile, offering a suitable salvage therapy for elderly patients with relapsed MM.

Terahertz imaging has drawn a widely attention for the potential applications in deep space exploration, material analysis, medical imaging, security screening, and situation awareness in fire disasters nowadays1–5. However, lack of large-format (many-pixels) sensor arrays, especially the fast imaging arrays, is one of the major hurdles for the proliferation of THz sensing methodologies and related applications5. Therefore, we fabricated a pixel-less photo-type terahertz imager based on the frequency up-conversion technique to realize the real-time and fast THz imaging. The device is composed of a terahertz quantum well photodetector (THz QWP) and a near-infrared light emitting diode (LED) that grown in sequence on the same substrate with molecular beam epitaxy. In such an integrated device (THz QWP-LED), electronics of the THz QWP in the bound state were excited to the continuous state to form photocurrent by absorbing of THz photonics, and it drives the LED to emit near-infrared light. The chip has a peak response of ∼0.5 A/W at 4.8 THz and a noise equivalent power (NEP) of ∼ pW/Hz0.5. We setup terahertz imaging systems to base on a quantum cascade laser (QCL) and a THz QWP-LED. The systems has an imaging resolution of ∼ $100\ \mu\ \mathrm{m}$ and a capacity of fast imaging within 10 µs. This device opens a new way to realize high performance real-time and fast terahertz imaging.


In this discussion note I clarify the motivation behind my original paper "Social Mechanisms, Causal Inference and the Policy Relevance of Social Science." I argue that one of the tasks of philosophers of social science is to draw attention to methodological problems that are often forgotten or overlooked. Then I show that my original paper does not make the mistake or fallacy that Daniel Steel suggests in his comment on it.


Aiming at a common copy-paste forgery in the research field of digital image forensics,this paper proposes a detection approach based on wavelet transform and singular value decomposition.Firstly,DWT is applied to the image,and SVD is used on fixed-size blocks of low-frequency component in wavelet sub-band to yield a reduced dimension representation.The representation is robust to minor variations in the image due to edge blurring.The SV vectors are then lexicographically sorted,and copy forgery regions are localized by detecting for all neighborhood vectors.The experiments demonstrate that the proposed approach can not only localize the copy forgery regions accurately,but also reduce the amount of computation and improve the detection efficiency.


High‐frequency gravity waves are analyzed using radiosonde soundings taken during the Tropical Warm Pool‐International Cloud Experiment (TWP‐ICE). The intrinsic periods of these waves are estimated to be between 10 and 50 min. The high‐frequency wave activity in the stratosphere, defined by mass‐weighted variance of the vertical motion of the sonde, has a maximum following the afternoon local convection indicating that these waves are generated by local convection. The wave activity is the strongest in the lower stratosphere below 22 km and, during the suppressed monsoon period, is modulated with a 3–4 day period. The concentration of the wave activity in the lower stratosphere is consistent with the properties of the environment in which these waves propagate, whereas its 3–4 day modulation is explained by the variation of the convection activity in the TWP‐ICE domain. For shallow convection, the wave activity has a weak tendency to increase as the rainfall intensity increases. The wave activity associated with deep convection, which typically occurs at high rainfall intensities, is larger and has more spread than that associated with shallow convection.


This paper describes the fresh and hardened properties of polyvinyl alcohol (PVA) fiber reinforced sustainable cement composite incorporating fly ash as a binder. For the fresh and hardened properties, flow value, compressive and direct tensile performance, cracking and crack-healing behavior of sustainable strain-hardening cement composite (SHCC) were investigated. For the SHCC mixes, three mixtures with various water-to-cementitious materials ratio (w/cm) were used and the PVA fiber volume content was fixed at 2.0%.


This figure shows the hexadactyly of feet and severe inflammation of the lower limbs of a 32-year-old Iranian female patient with Bardet–Biedl syndrome (BBS) who was referred to us with uraemic symptoms and metabolic acidosis.

She had suffered from insulin-resistant type 2 diabetes mellitus for 2 years and moderate hypertension for 6 months. Her parents had noticed progressive decline in her vision and hearing since the age of 7 years. She had mild mental retardation. She had irregular menstrual periods but her secondary sex characteristics were normal. Her parents were not consanguineous.

On physical examination, the patient was markedly obese with a body mass index of 31.4 Kg/cm2. She was dyspnoeic and often unwell. The blood pressure was 190/100 mmHg, axillary temperature 39°C, respiratory rate 22 beats/min, and heart rate 78 beats/min. Fundus examination revealed pigmentary retinopathy. Both lungs had coarse crackle in the basal field. Cardiac, abdominal and genital examinations were normal.

On admission, her blood glucose level was 482 mg/dL, blood urea nitrogen 190 mg/dL and serum creatinine 12.6 mg/dL. Blood revealed metabolic acidosis. Ultrasonography also showed bilateral small-sized high echogenic kidneys without cyst and hydronephrosis.

BBS is a rare autosomal recessive disease characterized by the abdominal obesity, mental retardation, pigmentary retinopathy, polydactyly and hypogenitalism. The degree of polydactyly, a prominent feature of this syndrome, varies from patient to patient, ranging from a wide fifth metatarsal or metacarpal to a complete sixth digit.

A set is called n-generic if it is Cohen generic for n-quantifier arithmetic. A (Turing) degree is n-generic if it contains an n-generic set. Our interest in this paper is the relationship between n-generic (indeed 1-generic) degrees and minimal degrees, i.e. degrees which are non-recursive and which bound no degrees intermediate between them and the recursive degree. It is known that n-generic degrees and minimal degrees have a complex relationship since Cohen forcing and Sacks forcing are mutually incompatible. The goal of this paper is to show.


Summary form only given. Numerous groups have demonstrated that tabletop high peak power femtosecond lasers are capable of inducing nonlinear self-focused propagation in atmosphere at 800 nm. The phenomenon unfailingly exhibits (1) light concentration in long single or multiple filaments of the order of 150 /spl mu/m diameter and tens of meters in length; (2) conical emission associated with these filaments has a considerably wider spectral content than the original laser pulse. Conical emission became apparent after the filaments were formed. While the divergence angle of these conical emissions has been studied, unfortunately there is no reasonable model proposed that can qualitatively describe (Brodeur et al, 1996; Nibbering et al, 1996) even the most basic features such as divergence angles of the different colors. Furthermore, the color ordering of these conical emissions can be changed upon changing the chirp of the launched pulse. In this paper, we present conical emission data to show its behavior as the pulse is chirped. In addition, we also present the spectral distribution of the conical emissions and how it depends on chirp. Finally, we compare our result with numerical result of Gaeta (Phys. Rev. Lett. vol. 84, pp. 3582-3585, 2000).


Across the different variety of loss decreasing methods, the loss-model-based methods (LMM) show a fast response and a low torque pulsation. Despite all the mentioned advantages, the approach needs the precise loss model and the knowledge of the motor parameters. Furthermore, the application of the model-based method is direct torque, and flux control is more complicated because the magnetic coefficients of the motor should accurately identify. In this paper, To solve the LMM's issues, a new model based approach has presented. The inaccuracy problem has fulfilled by dividing the homogenous parameters by each other. Via using this technique, the need for magnetic coefficient identification and the effect of inaccurate parameters have dwindled. Coupled with this, the requirement for computation of iron core loss coefficients have omitted by replacing of iron core loss resistance, which by this deed, in a manner, the estimation precision of iron core loss will enhance. At last, the proposed method had verified by simulation and the results are presented in table format, withal, the parameters of the simulated motor have identified by analyzing an induction motor (IM) in ANSYS Maxwell.


Aims Plant-plant interaction is fundamental in plant ecology.Many studies have examined the effects of environmental factors such as light,nutrients and water on plant-plant interactions,but few have tested the effects of waterlogging.Our objective is to investigate the effects of waterlogging on intraspecific interactions and test the hypothesis that waterlogging can modify the type and intensity of intraspecific interactions.Methods We grew plants of Alternanthera philoxeroides outdoors at three densities(1,4 or 16 plants in one pot) and four levels of waterlogging severity(water levels of-20(no waterlogging),0,20 or 40 cm).After three months,plants were harvested and data were collected.Important findings With increasing plant density or waterlogging severity,growth of A.philoxeroides decreased significantly.However,the effect of density differed greatly under different levels of waterlogging severity.With no waterlogging,the effect of density on growth was negative and the competition intensity was high.With water levels of 0 and 20 cm,the density effect was still negative,but the intensity decreased.With a water level of 40 cm,however,the density effect was positive.Moreover,waterlogging severity significantly affected the relative neighbor effect and its values increased gradually from negative(under no waterlogging) to positive(in 40 cm).The results support a stress-gradient hypothesis and suggest that waterlogging can affect intraspecific interactions.With increasing waterlogging severity,intensity of competition decreases while that of facilitation increases.


Systematics are improved for application to reactions induced by 14-MeV neutrons. On the basis of this approach, new parameters for nucleon emission reactions are derived from Legendre polynomials fit 18- 25-MeV (p,n) and 18-MeV (p,p{prime}) data. For alpha-particle emissions, separate parameterizations are performed for equilibrium and preequilibrium components: Legendre coefficients obtained from calculations are parameterized for the former and the procedure used for nucleon emissions is applied to the latter. The angular distributions calculated using the present parameters show good agreement with those for 14-MeV (n,n{prime}), (n,p), and (n,{alpha}) reactions.


The effects of methylflavonolamine(MFA) on bronchoactive agents-induced contractionsand bronchodilators-induced relaxations were studiedon guinea-pig isolated trachea and compared withthat of verapamil (Ver) and trifluoperazine (Tri). At0.1-0.3 mmol · L-1, MFA timedependently relaxedthe contraction induced by 40 mmol · L 1 KCl. Atconcentration below 0. 1 mmol · L -1 , MFA produced anegligible relaxation on KCl-induced contraction, butsignificantly shifted the isoprenaline (lso) andaminophylline (Ami) concentration-relaxation curvesupwards to the left. MFA. Ver, Tri and Ami inhibitedthe contractions induced by submaximal concentra-tions of physiologic agonists. The inhibitory potencyorder was Tri Ver = MFA Ami. MFA. Ver and Trishifted CaCl2 cumulative curves downwards to theright with the pDz values 5.0± s 0.5, 6.4± s 0.8 and5.0± s 0.6, respectively. The present results show thatMFA is relatively potent to antagonize physiologicbronchoconstrictors and have synergistic action withIso and Ami in bronchodilation. It is also suggestedthat MFA may have non-selective calcium antagonis-tic action and resemble Tri more closely than Ver orAmi in the mechanism of action.


Low-light image processing is a common issue in industry, media and other practical application fields. Enhancing image brightness or contrast directly may bring accompanying noise and color cast. The proposed method is a feature based deep F-Retinex-Net. A neural network is used to decompose the image into features representation of reflectance component and illumination component. The feature of illumination component was enhanced, and then the features are used to reconstruct the enhanced image by another network. The convergence of the observation model is confirmed by observing the state of illumination and reflectance features by visualization method. Experimental results show that F-Retinex-Net has better performance enhancement effect than Retinex-Net, and can also greatly alleviate the color distortion problem.


Martin Heidegger devotes extensive discussion to medieval philosophers, particularly to their treatment of Truth and Being . On both these topics, Heidegger accuses them of forgetting the question of Being and of being responsible for subjugating truth to the modern crusade for certainty: 'truth is denied its own mode of being' and is subordinated 'to an intellect that judges correctly'. 1 Though there are some studies that discuss Heidegger's debt to and criticism of medieval thought, particularly that of Thomas Aquinas, there is no constructive reply to his assertions. 2 As a result, Heidegger's critique had an unprecedented effect on the credibility of medieval philosophy, whereby great portions of the philosophical community dismiss it altogether as an illegitimate Onto-Theology . It is the aim of this study to offer a constructive reply that will fundamentally grapple with these allegations. By constructive reply we mean not only a reply that avoids the problems Heidegger raises regarding existence, essence and truth, but more importantly, one that uses Heidegger's criticism in order to present a more insightful account of these notions. The present study is composed of two parts where the second serves as a sort of addendum. The first part, the core of this study, is an attempt to develop an understanding of the distinction between essence and existence that, on the one hand, accords with Heidegger's criticism while on the other hand advances our understanding of how we think and understand reality. After presenting Heidegger's depiction of Aquinas's distinction between essence and existence ( esse ) as a real distinction, the study will present several views propounded by scholars of Aquinas regarding the status of this distinction. It will be argued that it is not clear whether the distinction is real, formal or conceptual, and that different types of distinction are applied Abbriviations: ST = Thomas Aquinas, Summa Theologiae , trans.

The effect of different mixed fertilizers on the growth and development in Stevia Rebaudiana Bertoni had been studied in the open field. The results showed that the growth rate, plant height, stem thickness, leaf areas and dry matter weight using organic cultivation were less than that of using the chemical fertilizers in the early stage after transplanting. But 60 days after transplanting, there were no significant differences among the treatments in agronomic characters besides the no applying fertilizer treatment. However, there were significant differences in growth and development between organic cultivation and using the chemical fertilizers in 80 days after transplanting.


Mutations in MYH9 gene that encodes for actin associated molecular motor nonmuscle myosin II (NM2) result in kidney disease in some patients. Based on our previous work that demonstrated a novel role for NM2 motors, we hypothesized that NM2 genes might play a critical role in renal epithelial transport. To test our hypothesis, we generated pan renal tubular conditional knockout (cKO) of Myh9&10 in adult mice that resulted in progressive kidney disease of TAL origin with aberrant transport of TAL cargoes UMOD and NKCC2 (Otterpohl et al; 2020). To confirm the cell‐autonomous role for NM2 proteins in adult TAL epithelium, we generated a TAL‐specific cKO mouse model of Myh9&10using a TAL specific cre transgenic mice, UMOD‐>CreERT2. Cre transgene was induced at 5 weeks of age with tamoxifen injections, age matched control and cKO littermates were part of every cohort. The mice underwent metabolic, histologic, immunohistochemical, and biochemical analysis at varying time points until moribund. The TAL‐specific Myh9&10 cKO mice develop progressive kidney disease indicated by increase in BUN and serum creatinine as well as increasing levels of the tubular injury marker, NGAL. Our results show that Myh9&10 TAL‐ cKO females had significant loss of weight at 12 weeks, the female cKO animals became moribund between 13 – 14 weeks, while the male cohorts survive up to 25 weeks. Histology confirmed the tubulointerstitial disease in Myh9&10 TAL‐cKO with dilated tubules and cellular infiltration. Urine pH declined starting at 9‐weeks of age in females and 12‐week in males. Interestingly, female cKO mice have hypernatremia at 12‐weeks of age compared to male mice which maintain normal sodium levels. Since the pan renal tubular Myh9&10 cKO exhibited loss of NKCC2 leading to salt wasting, this result was unexpected. We analyzed NKCC2 protein levels in kidney lysates, loss of NKCC2 was evident in both female and male Myh9&10 TAL‐cKO. We also observe significant decline in serum potassium levels in 7.5‐week females. We speculated that the hypernatremia in TAL‐Myh9&10 cKO females is due to tubular adaptation in the distal nephron and the collecting duct. Characterization of sodium cotransporters and channels in distal nephron and collecting duct segment revealed an increase in NCC/pNCC levels in males and a decrease in females. Immunostaining experiments showed increase in ENaC gamma expression in the cortical collecting ducts of the females. This could potentially explain the hypernatremia and early morbidity observed in Myh9&10 TAL‐cKO females. We speculate that females upregulate ENaC gamma to compensate for loss of NKCC2, instead males upregulate NCC/pNCC that prevents their early lethality. These experiments confirm the critical role for Myh9&10 proteins in TAL tubule and identify a novel, sex specific tubular adaptation mechanisms. NM2 motor regulating the unique, TAL‐specific sodium cotransporter is intriguing and warrants further analysis. Our model also provides a good resource for understanding the sex‐specific differences of sodium handling and potentially clarify mechanisms underlying Type I Bartter Syndrome.


Non-agaric macrofungi of Hamedan province (Iran), belonging to the genus Verpa Sw. (family Morchellaceae), were collected and identified based on morphological features (Dennis 1981 and Haffner 1991).


We describe a procedure to systematically improve direct diagonalization results for few-particle systems trapped in one-dimensional harmonic potentials interacting by contact interactions. We start from the two-body problem to define a renormalization method for the interparticle interactions. The procedure is benchmarked with state-of-the-art numerical results for three and four symmetric fermions.


Objective To investigate the expression of the RKIP protein in the cervical tisssue and the relationship of the RKIP with the clinical and pathological of the cervical cancer.Methods Immunohistochemical study was used to study the expression of the RKIP protein in the normal cervical tissue,cervical intraepithelial neoplasia,cervical cancer and its metastatic lymph nodes ; RT-PCR and Western Blot methods were also used to study the expression of the RKIP in the four kinds of the cervical cancer cells,we analysed the the relationship of the RKIP with the clinical and pathological of the cervical cancer.Results RKIP expression level was lower in cervical cancer than in norma cervical tissue and cervical intraepithelial tissue (x2 =9.211,P < 0.05 ).There was no difference in the expression of the RKIP between the normal cervical tissue and cervical intraepithelial tissue (x2 =0.805,P > 0.05 ).RKIP expression had a correlation with lymph node metastasis (x2 =10.341,P < 0.05 ).No significant correlation were observed between RKIP expression and clinical stage,microscopic subtype or pathology differentiation grade,(x2 =0.190、4.101、1.402,P >0.05).The result of the RT-PCR and western blot showed the RKIP expression level was lowest in high investive Caski cervical cancer cells (x2 =4.08,P < 0.05 ).Conclusion RKIP may play a role in the genesis and metastasis of cervical cancer.Reduction of RKIP expression is a hallmark of metastatic disease in human cervical cancer.

The batch removal of Cr(VI) from aqueous solution using low-cost adsorbents such as cornelian cherry, apricot stone and almond shell under different experimental conditions was investigated in this study. The influences of initial Cr(VI) ion concentration (20 to 300 mg·l-1), pH (1 to 4) and particle size (0.63 to 1.60 mm) have been reported. Adsorption of Cr(VI) is highly pH-dependent and the results indicate that the optimum pH for the removal was found to be 1 for all types of carbon. A comparison of kinetic models applied to the adsorption of Cr(VI) ions on the adsorbents was evaluated for the pseudo first-order, the pseudo second-order, Elovich and intraparticle diffusion kinetic models, respectively. Results show that the pseudo second-order kinetic model was found to correlate the experimental data well.


Introduction All first responders must be prepared to respond to suicide attacks. Staging safe and effective responses to these incidents requires knowledge of a number of unique considerations. Methods The research presented in this presentation used reviews of open source information along with site visits to multiple suicide bombing sites in Israel and the United Kingdom to determine the important considerations for first responders responding to suicide attacks. What is presented is not a specific standard operating procedure but rather a common framework that can help to facilitate a coordinated and effective response from all agencies involved. Results Civilians and private security guards can play an important role in detecting the planning and execution of suicide attacks and sometimes even in their interdiction in the imminent attack phase. The suspicions of civilians must be taken seriously and citizens should be encouraged to report these suspicions immediately. The first responding emergency services personnel must be able to effectively begin their agency's response to the attack while maintaining a strong situational awareness. Also on scene, strong frontline commanders are needed to work together to lead a coordinated response. Interagency communication and using a scaled response is of increased importance at these incidents when first responders could be targeted by the secondary attacks or an initial threat that has not yet been neutralized. First responders can take the initial steps to promote the return to normalcy that is important after terrorist attacks. In the aftermath of attacks, efforts should be made to establish a collective knowledge within the emergency services community to share lessons learned in the response. Conclusion The results of this research can help local agencies plan for suicide attack response and also provides a strong foundation for future research to further investigate responses to the varying types of suicide attacks around the world.


The bike-sharing system (BSS) aims to provide an alternative mode of public transportation that are being adopted in urban cities. The use of the bike for short-distance travel aids in mitigating traffic congestion problems, reduce carbon emissions, and decrease the risk of overcrowding during a pandemic like COVID-19, thereby satisfying the urban-mobility needs of the residents. The key success of incorporating urban-mobility through BSS lies behind the prediction of bikes by identifying the pick-up and drop-off operations in each station. The main challenge includes the demand prediction for the number of bikes available for pick-up and drop-off during a specific point in time. Quantum Computing has been increasingly gaining popularity for its superior computational performance over similar classical algorithms. In this paper, we will illustrate potential applications of Quantum Bayesian networks, which are quantum-equivalent to classical Bayesian networks for probabilistic bike demand prediction.


The invention relates to an automatic bamboo pole sawing device which is characterized in that a plurality of material cutting devices are arranged on a saw table in parallel; each material cutting device comprises a material cutting motor; the material cutting motor is connected with a saw blade through a material cutting conveyor belt; the material cutting devices are movably mounted on a material cutting frame; material cutting cylinders used for pushing the material cutting devices to move forwards or backwards are arranged behind the material cutting devices; material cutting solenoid valves are mounted on high-pressure air inlet pipes of the material cutting cylinders; the material cutting devices are positioned on a same straight line; the distance between the every two saw blades of the material cutting devices is equal to the length of a bamboo pole required to be cut down; the material cutting devices simultaneously move forwards, saw off the whole bamboo pole at a time and are mounted on the saw table through bolts; the distance between the every two material cutting devices can be adjusted according to the length of a bamboo segment to be sawed.

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder that affects cognitive function, behavior, and social interaction. While medication and behavioral therapy are the standard of care for ADHD, complementary and alternative interventions that leverage the brain's neuroplasticity, such as brain rewiring techniques and digital technologies, have emerged. These techniques, including cognitive-behavioral therapy, mindfulness-based interventions, neurofeedback, Neuro-Linguistic Programming, clinical hypnosis, exercise, yoga, music therapy, and working memory exercises, aim to modify the function and structure of the brain to improve cognitive function, self-regulation, and overall quality of life in individuals with ADHD. Additionally, virtual reality has shown promise as a potential tool for improving attentional control and reducing ADHD symptoms. This literature review provides an overview of the effectiveness of brain rewiring techniques, including NLP and clinical hypnosis, as well as exercise, yoga, music therapy, and working memory exercises for ADHD, and the potential utility of virtual reality for treating ADHD.


The search for increasing Sea Power operational and management capabilities has promoted the use of hybrid systems, in which cyber components interact with physical plants and with sensors/devices that explore the electromagnetic spectrum. However, at the same time as this integration brings benefits, it also exposes such systems to new threats resulting from the encounter of cyberwarfare with electronic and kinetic warfare. This study analyzes how these new threats can affect Sea Power, characterizing, through examples, their possible targets. To support this discussion, we propose a taxonomy encompassing new classes of attack that exploit the cyber, electronic and kinetic domains. Our analysis indicates the need for policies capable of promoting Sea Power cyber security. In this sense, we discuss policies on personnel training and certification of cyber products, both of them having the potential to contribute extensively to Sea Power security.

Polycondensation reaction of 5-(4-acetoxy-benzamide) isophthaloylchloride with different aromatic diamines gave a series of polyisophthalamides with good solubility in organic solvents. These polymers showed good thermal stability with initial decomposition temperature above 300 °C and glass transition temperature in the range of 220-335 °C. Thin, flexible, transparent films were cast from solutions, having good electroinsulating properties.


University rankings have gradually become an issue for concern in the academic community worldwide. Several mechanisms with different methodologies have been developed to rank the universities appropriately. However, some ranking tools have notable issues, especially with the indicators adopted. Some are based merely on research performance, whilst others have focused solely on specific fields, such as science and technology - which could have deprived those in the arts and social sciences. This paper uses a narrative review to highlight a number of inconsistencies in the methodologies applied to rank universities. Five main ranking tools commonly applied to the world's universities are reviewed, namely Quacquarelli Symonds (QS), Times Higher Education (THE), Academic Ranking of World Universities (ARWU), Leiden University ranking and Webometrics ranking. We found that several flaws in the rankings caused inconsistencies in university placings in different rankings. Suggestions for integrating multiple criteria and indicators for better ranking exercises are proposed.


The invention relates to a thermoplastic polyester alloy nano-composite material and a method for preparing the same, the composite material has ingredients and mass percents of: 50-95% of polybutylene terephthalate (PBT), 0-40% of polyethylene terephthalate (PET), 0.1-5% inorganic nano-materials subjected to surface treatment with a coupling agent and 0-5% of other auxiliary agents; the ingredients are molten and mixed together at the temperature ranging from 210-265 DEG C to obtain the thermoplastic polyester alloy nano-composite material. The polyester alloy nano-composite material prepared by the method results in high dispersion in the nanoparticles thereof, which effectually prohibits transesterification reaction between the polyester alloys and prominently enhances the heat resistance of the polyester substrate; the polyester alloy nano-composite material also has excellent surface finish, which lowers the costs while advancing tensile strength and flexural modulus thereof and can be applied to the manufacturing of parts in automobile industry and electronic industry extensively.

Valence level photoelectron spectra of gaseous acetylene excited by HeI (21.217 eV), HeII (40.8 eV), Zr Mζ (151.4 eV) with Mg Kα (1253.6 eV) radiations have been obtained. With one exception, the 3σg band under Mg Kα excitation, all of the expected valence level excitations are observed in each case. The best measured orbital ionization potentials are 1πu (11.41 eV), 3σg (16.76 eV), 2σu (18.71 eV), and 2σg (23.65 eV). All values except that for 1πu are adiabatic values. Relative photoionization probabilities (cross sections) have been determined for each of the radiations and compared to those estimated theoretically. The low calculated cross sections for 3σg excitation with Mg Kα radiation provides an explanation for the lack of an observable band due to this ionization in the photoelectron spectrum. A prominent ''shake‐up'' peak is observed at 27.6 eV in both the Mg Kα and Zr Mζ excited valence shell photoelectron spectra although it is more pronounced in the former. Similarly the C1s core spectrum show...


HE motives of France for entering the War of American Independence have been the subject of considerable speculation and controversy. At present the generally accepted interpretation is that of Professor Edward S. Corwin, • although the late Professor Claude H. Van Tyne championed a different theory and recently brought forward new evidence in support of it. 2 His view is that France felt it necessary to engage in a preventive war to protect her West Indian possessions from an Anglo-American attack due to follow any reconciliation between the colonies and the mother country. Mr. Corwin disputes this, as also the correctness of the older theories that France was moved by a desire to re-acquire territory or commerce in America or that public opinion forced her into the war. He asserts that the only important motive of the French government was the aggressive desire to restore a "balance of power favorable to France" by securing the disruption of the British Empire. At first glance these theories appear to be irreconcilable, but they really are not, for both the defensive and the aggressive motive could easily have existed at the same time--such a mixture of motive is, indeed, characteristic of the idea of preventive war. But were these the only motives? Mr. Corwin's study, which gives the broadest discussion of French motives, is based principally upon the great work of Henri Doniol. 3 A careful examination of this work and of evidence from other sources convinces the present writer, however, that it fails to supply all the information necessary for an accurate analysis of French motives. In all probability a more extensive and searching study than has so far been attempted would reveal that French aims were much more complex than has been thought. In order to show the need for further investigation, it is proposed to consider here the available evidence on one French motive that has been almost entirely neglected, namely France's desire to better her position in the Newfoundland fishery.


Perception plays a key role in the development of intelligent autonomous systems. In particular object recognition and registration tasks are crucial to any intelligent autonomous system such as autonomous cars or personal robots. The representation of 3D object sensor measurements largely affects the choice of higher level processing possible on the sensor data. We explore the use of scale space theory via the curvature scale space and extend it to represent 3D objects in our new SCSS (Sliced Curvature Scale Space) framework. We further develop techniques of further processing the SCSS representation including feature extraction and dimensionality reduction for use in learning frameworks. We perform an array of experiments to validate the effectiveness of our method and demonstrate recognition performance using support vector machines. The results indicate that our new representation retains the nice qualities of the original curvature scale space method while being robust and compact for 3D object representation and recognition.


Abstract Glutamine is a key amino acid participating in various metabolic pathways. Study of the physiology of its carbon skeleton has been hampered by lack of a simple and precise method to measure its [14C] specific activity in plasma. The present report describes an automated, sensitive and specific method to determine plasma [14C] glutamine specific activity which can be used to measure glutamine carbon turnover and substrate-product interactions in vivo. An orto-phtalaidehyde derivative is analysed on a reverse phase column by UV detection. With this procedure μMol amounts of glutamine and other plasma compounds can be assayed for [14C] specific activity. The method is sufficiently fast (25 samples in 24 hrs) and reproducible (CV<5.5%) for accurate measurements in a large volume of samples.

We report a detailed observational study of the single pulses from the pulsar J1822$-$2256. The pulsar shows the presence of subpulse drifting, nulling as well as multiple emission modes. During these observations the pulsar existed primarily in two modes; mode A with prominent drift bands and mode B which was more disorderly without any clear subpulse drifting. A third mode C was also seen for a short duration with a different drifting periodicity compared to mode A. The nulls were present throughout the observations but were more frequent during the disorderly B mode. The nulling also exhibited periodicity with a clear peak in the fluctuation spectra. Before the transition from mode A to nulling the pulsar switched to a third drifting state with periodicity different from both mode A and C. The diversity seen in the single pulse behaviour of the pulsar J1822$-$2256 provides an unique window into the emission physics.


Polypyrrole (PPy)/montmorillonite (MMT) nanocompounds were prepared by in situ chemical oxidative polymerization of pyrrole in the presence of MMT. The results indicate PPy is intercalated into MMT interlayers and the morphology of obtained PPy in nanocompounds is changed to flake-like rather than granular particles as pristine PPy. The resultant PPy/ MMT nanocompounds and pristine PPy were used as microwave absorbing filler separately to prepare microwave absorbing PPy/MMT and PPy epoxy composites. The results indicate PPy/MMT epoxy composites exhibit much better microwave absorbing properties than those filled by pristine PPy. The maximum reflection loss of 20 wt% PPy/MMT filled composite is 232.63 dB at 10.55 GHz with a matching thickness of 2.8 mm, and the effective absorption bandwidth with the reflection loss below 210 dB is from 8.6 GHz to 12.4 GHz, which almost covers the whole X-band. We postulated that the morphology change of PPy in PPy/MMT and its better dispersion may be responsible for the enhancement of microwave absorption. POLYM. COMPOS., 00:000–000, 2014.

YOSI NURHAYATI. Resilient Backpropagation Neural Network Model Development To Identify Guitar Chord. Supervised by AGUS BUONO. This study developed a sound recognition to identify guitar chords by using resilient backpropagation neural network as the pattern recognition method and MFCC as the feature extraction method. The aim of this study is to find the parameters that can produce the highest accuracy. The parameters used in the process of resilient backpropagation pattern recognition are the hidden neurons, error tolerance, learning rate, up factor, down factor, delta0, and deltamax. Meanwhile the parameters used for the MFCC are the sampling rate, time frame, overlap, and the number of cepstral coefficient. There were 8 640 data utilized in this study, which were obtained from 24 different chords. It was found that a highest accuracy of 95.56% can be obtained by using 100 hidden neurons, 52 numbers of cepstral coefficient, overlap score of 0.4, and the time frame of 100 ms.
