FIELD: electricity. SUBSTANCE: bench for thermal and strength tests contains radiation heaters, auxiliary heaters in the area of the most heat-stressed and heat-consuming areas of a tested object and these heaters are equipped with individual adjustable voltage sources and power load system. The auxiliary heaters are made as contact heaters with resistive elements pressed by electric contacts directly to the electroconductive surface of the most heat-stressed and heat-consuming areas of tested object and one pole of the electric contacts is jointed by the common bus. The resistive elements are made as a double-layer pack of electroconductive particles of high-temperature materials and transient resistance values between them define the total resistance of the resistive element. The pack layer adjoining tested object has larger resistance value, and size of the pack, particles and degree of their compression are defined experimentally. EFFECT: provision of required temperature for the most heat-stressed and heat-consuming areas of tested object thus ensuring the closest approximation of the test conditions to the actual ones. 1 dwg


This paper presents a study of the improvement in efficiency of the Rabin-Karp patternmatching algorithm based Deep Packet Inspection. NVIDIA GPU is programmed with the NVIDIA's general purpose parallel computing architecture, CUDA, that leverages the parallel compute engine in NVIDIA GPUs to solve many complex computational problems in a more efficient way than on a CPU. The proposed CUDA based implementation on a multicore GPU outperforms the Intel quadcore processor and runs upto 14 times faster by executing the algorithm in parallel to search for the pattern from the text. The speedup may not sound exorbitant but nonetheless is significant, keeping in view that the experiments have been conducted on real data and not synthetic data and, optimal performance even with the huge increase in traffic was the main expectation, not just an improvement in speed with few test cases.


Oroxylum indicum, Sonapatha is traditionally used to treat asthma, biliousness, bronchitis, diarrhea, dysentery, fevers, vomiting, inflammation, leukoderma, skin diseases, rheumatoid arthritis, wound injury, and deworm intestine. This review has been written by collecting the relevant information from published material on various ethnomedicinal and pharmacological aspects of Sonapatha by making an internet, PubMed, SciFinder, Science direct, and Google Scholar search. Various experimental studies have shown that Sonapatha scavenges different free radicals and possesses alkaloids, flavonoids, cardio glycosides, tannins, sterols, phenols, saponins, and other phytochemicals. Numerous active principles including oroxylin A, chrysin, scutellarin, baicalein, and many more have been isolated from the different parts of Sonapatha. Sonapatha acts against microbial infection, cancer, hepatic, gastrointestinal, cardiac, and diabetic disorders. It is useful in the treatment of obesity and wound healing in in vitro and in vivo preclinical models. Sonapatha elevates glutathione, glutathione-s-transferase, glutathione peroxidase, catalase, and superoxide dismutase levels and reduces aspartate transaminase alanine aminotransaminase, alkaline phosphatase, lactate dehydrogenase, and lipid peroxidation levels in various tissues. Sonapatha activates the expression of p53, pRb, Fas, FasL, IL-12, and caspases and inhibited nuclear factor kappa (NF-κB), cyclooxygenase (COX-2), tumor necrosis factor (TNFα), interleukin (IL6), P38 activated mitogen-activated protein kinases (MAPK), fatty acid synthetase (FAS), sterol regulatory element-binding proteins 1c (SREBP-1c), proliferator-activated receptor γ2 (PPARγ2), glucose transporter (GLUT4), leptin, and HPV18 oncoproteins E6 and E7 at the molecular level, which may be responsible for its medicinal properties. The phytoconstituents of Sonapatha including oroxylin A, chrysin, and baicalein inhibit the replication of SARS-CoV-2 (COVID-19) in in vitro and in vivo experimental models, indicating its potential to contain COVID-19 infection in humans. The experimental studies in various preclinical models validate the use of Sonapatha in ethnomedicine and Ayurveda.

The new species is most similar to Bachia psamophila from which it differs in limb morphology and head and body scalation. As in Bachia psamophila the shovelshaped snout of the new species is highly prominent, an adaptation related to its psamophilous habits.


Satellite remote sensing retrieval has shown excellent competence at retrieving the aerosol distribution and properties comparing with traditional detection. The extended dark dense vegetation (DDV) algorithm for MODIS data was used widely all over the worl d. However, whether this algorithm can be transferred to high reflectivity areas of China is not known yet, especially in urban area and its surroundings. In this paper, we attempt to derive Aerosol Optical Depths (AOD) by exploiting the extended dense vegetation algorithm and TERRA/MODIS data. Preliminary validation results by comparing with in situ measured data show good accuracy and promising potential in different seasons of China urban areas.


The mass spectra of a series of pentafluorophenyl derivatives of phosphorus have been examined. Bond-forming rearrangements were observed such as elimination of PF2 from the (C6F5)2P+ species giving (C6F4)2+, and elimination of successive molecules of FeF2 from [(C6F5)2PFe]2+. Some Group IV pentafluorophenyl derivatives and two pentachlorophenyl compounds were also examined.


This paper describes the design and development of a trilingual spontaneous speech corpus for statistical speech-to-speech translation. The languages considered are Catalan, Spanish and US-English. This corpus has been built bearing in mind the strong need for multilingual collections of on-line data within the area of statistical translation, as well as the need for data that are parallel or aligned, that contain different types of linguistic information and that can be used by different translation systems. For that reason, our aim has been the creation of a linguistically-enriched resource with an XML-based DTD that allows a useful, transparent and flexible storage of the data. Moreover, these resources are also valuable for a wide range of Natural Language Processing applications, such as multilingual resource acquisition or word sense discrimination, among others.


This paper describes case histories of the use of the electric ion-extracting (CHIM) method and soil gas mercurometric surveys in search of concealed gold deposits, as well as the preliminary results obtained in the application of the newly developed geogas method in prospecting for concealed gold deposits. Experiments on the effectiveness of the CHIM method were carried out over a known gold deposit in the arid and semiarid Gobi desert of Xinjiang. A CHIM gold anomaly was revealed over the known orebody, with values tens to hundreds of times higher than the background. Two peaks were identified across the orebody; the peak value on the side to which the orebody was inclined was higher than that on the other side. Later, a CHIM survey was carried out along a 20-kilometer survey line and, consequently, quite a few CHIM Au anomalies were detected, with intensities ranging from 40 to 1000 ppb. The location of a test drillhole was determined on the basis of the CHIM gold anomaly and it intersected a concealed...


EDMC represents extended dynamic matrix control, which can be applied to nonlinear process control. In this method, control inputs are determined based on a linear model that approximates the process and is updated during each sampling interval. Since nonlinear relation still exists between the prediction error and the control input, numerical (iterative) methods are used to solve the optimization problem defined in the method. For nonlinear processes with high variation and/or sign changes in their steady‐state gain, iterative methods do not converge properly to an acceptable solution for some desired outputs or external disturbances. To eliminate the problem, we augment the process with its steady‐state gain inverse (or pseudo inverse whenever required) such that the steady‐state gain for the new augmented system is constant or contains slow variations. In the case of unstable processes, the method may be applied after stabilizing the process using a proper state or output feedback. Effectiveness of the method has been examined using computer simulations of some benchmark processes. Some of the obtained results are presented in this paper.


Since the discovery of the first asteroid by Piazzi in 1801, orbits have been determined for over 2500 with varying degrees of quality; 2357 have been assigned permanent numbers as of this writing (Marsden and Bardwell 1981).


he main goal of the paper is to present procedures and analysis of the measurement that must be performed and the compulsory results to obtain compliance with conducted and radiated electromagnetic emissions. After the introductory section which outlines generalities related to electromagnetic compatibility (EMC), the second section focuses on the dichotomy between near-field and far-field, present in two important zones where electromagnetic phenomena are totally different, which however are not well enough highlighted in the specific EMC standards. The third section is devoted to emission measurements that must be performed in different electromagnetic environments and for different types of equipment depicted in the specific standards in force. As an example, the case of electromagnetic emissions produced by a household gas thermal power unit is presented.


Decay and quality loss severely affect the marketability of fresh zucchini. Zucchinis are easily damaged during harvesting, handling and storage, and no commercial treatment is currently available that can protect the fruit from desiccation, quality loss and decay. The aim of this study was to compare different environmentally friendly dipping treatments (CaCl2, Aloe vera, warm water, chitosan, ascorbic and citric acid) to retain the quality of fresh zucchini. Treated fruit were evaluated for physiological, sensory and microbiological parameters after storage for 7 and 14 days at 5.8C and 85% relative humidity. The CaCl2, Aloe vera and warm water treatments were the most effective in maintaining firmness and preventing an increase in the total microflora of the fruit. The outcome of this study shows that alternative control methods have potential for effective quality maintenance of fresh zucchini. Future studies should focus on alternative packaging materials in combination with these treatments.

Practical Applications

Zucchinis are rich in carbohydrates, minerals and vitamins and are good nutritional additives to a balanced and healthy diet. Recent observations at retail level showed preventable quality losses, indicating the need to improve postharvest technologies for retaining the overall standard of the product after harvest and during the supply chain. Quality parameters include firm texture, shiny, dark-green skin color and freedom from shrivel and mechanical injuries. The assessment of different environmentally friendly dipping treatments indicated that CaCl2, Aloe vera and warm water treatments could lead to improved quality maintenance of zucchinis. Practical applications stemming from these results include the ability to extend shelf life and preserve the microbiological profile of this fruit after harvest. These treatments may serve as alternatives to chemical or synthetic treatments and may be considered as an inclusion to current postharvest management practices.

Decentralized networked feedback control laws are designed for Multi-generator Interconnected Power System Automatic Generation Control (AGC) which controlled over networks in the power market. The dynamic model of Interconnected Power System AGC is treated as an interconnected system with overlapping states. Using the mathematic framework of the Inclusion Principle, the interconnected system is expanded into a higher dimensional space in which the subsystems appear to be disjoint. Then, for the locally extracted subsystems with respect to network-induced time-delay and packet-dropout, by modeling the Networked Control System (NCS) as an Asynchronous Dynamic System (ADS) with rate constraints on events, the state feedback controllers are designed and the sufficient exponential stability criterion is derived. The design procedure is based on Linear Matrix Inequalities (LMI). As a final step, the decentralized controllers are contracted back to the original space for implementation. A 2-generator simulation example is given to show the effectiveness of the method.


As telecommunication systems become more complex and more antennas are placed on the same structure (e.g., helicopter airframe) the problem of interference becomes significant for the performance of the systems. The finite-difference time-domain (FDTD) method is used to calculate coupling between wire elements; e.g., monopoles and loops mounted on ground planes and helicopter airframes. Also, rotor modulation effects on coupling are investigated. All the numerical results obtained by FDTD are validated by comparison with measurements.


New York, Sept. 16, 1897. To the Editor: —Your issue of September 11, contains the very interesting article on "Streptococcic Infection and Marmorek's Serum," by Geo. W. Cox, M.D., of Chicago. In the discussion following the reading of the paper, Dr. Cox states that there is no work on the subject that he knows of, except his communication. May I take the liberty to call his attention to some experimental and clinical work done in that line by myself over a year and a quarter ago? The results of these experiments I communicated to the Academy of Medicine of New York at its meeting of Jan. 21, 1897, in a paper entitled "The Hygienic, Educational and Symptomatic Treatment of Pulmonary Tuberculosis," which subsequently appeared in the Medical Record of February 13. Three years ago, when I began visiting the European sanatoriums for consumptives for the purpose of studying this phase

The purpose of the current analysis was to evaluate the cost‐effectiveness of chemoprevention utilizing a quality‐of‐life adjustment.


In this paper, the adaptive fault detection and estimation problems are investigated for a class of linear multi-agent systems with sensor faults, and adaptive neighborhood-observer-based approaches are respectively proposed to detect and estimate the faults. By applying graph and stability theory, it is proved that the detection and estimation errors converge to an adjustable small neighborhood of the origin with all signals in the closed-loop system being bounded. Finally, simulation results demonstrate the effectiveness of the approach proposed in this paper.


ABSTRACT The 'Trapped-Fetch Wave Model (TFWM)', which is developed for wave prediction in north Atlantic hurricanes, is applied to typhoon cases in western North Pacific (WNP). The comparison with operational numerical ocean wind wave prediction system at Korea Meteorological Administration (KMA) is examined. In application to WNP typhoon, the TFWM has shown some advantage against typical operational spectral wave models. Even though the full spectral 3rd generation numerical wave model can provides a reliable wave field prediction, it has little value when the atmospheric model poorly predicts the location and intensity of concerned storms or tropical cyclone. The analysis of TFWM output should lead the forecaster back to a more in-depth examination of the full spectral wave model output, resulting in an improved forecast product. As a supporting guidance tool for marine forecaster, the TFWM has shown its own uniqueness and necessity.


Introduction: According to the Rome III Criteria, functional dyspepsia (FD) is classified as post-prandial distress syndrome (PDS) and epigastric pain syndrome (EPS). On the other hand, the satiety test (ST) has been used to evaluate gastric accommodation and emptying, distinguishing healthy individuals from those with dyspepsia. Aims: To determine whether the ST can distinguish dyspeptic individuals from healthy ones and to evaluate its usefulness in differentiating the two FD subtypes. Methods: Adults with FD were consecutively enrolled in a cross-sectional study within the timeframe of August 2011 and October 2012. Healthy subjects participated as controls. The ST consisted of the intake of a nutritional supplement (Fortisip ® , Nutricia Bagó ® )


This note is a summary of our work [OO] which provides an explicit and global moduli-theoretic framework for the collapsing of Ricci-flat Kahler metrics and we use it to study especially the K3 surfaces case. For instance, it allows us to discuss their Gromov-Hausdorff limits along any sequences, which are even not necessarily "maximally degenerating". Our results also give a proof of Kontsevich-Soibelman [KS04, Conjecture 1] (cf., [GW00, Conjecture 6.2]) in the case of K3 surfaces as a byproduct.


High-fidelity quantum operations are a key requirement for fault-tolerant quantum information processing. Manipulation of electron spins is usually achieved with time-dependent microwave fields. In contrast to the conventional dynamic approach, adiabatic geometric phase operations are expected to be less sensitive to certain kinds of noise and field inhomogeneities. Here, we introduce an adiabatic geometric phase gate for the electron spin. Benchmarking it against existing dynamic and nonadiabatic geometric gates through simulations and experiments, we show that it is indeed inherently robust against inhomogeneity in the applied microwave field strength. While only little advantage is offered over error-correcting composite pulses for modest inhomogeneities 10%, the adiabatic approach reveals its potential for situations where field inhomogeneities are unavoidably large.


Efficacy of four compounds was evaluated in two tests. Each treatment was replicated three times (1 tree per replicate) in a completely randomized design. Treatments were applied on 7 Jun. (test 1) and 15 Jun. (test 2) with a five horsepower hydraulic sprayer set at 350 lb/in.2 A handgun with a No. 4 disc was used to apply 1.6 gal of spray per tree (400 gpa). The mite level in check trees remained below 70 active mites per leaf throughout the tests, a moderate mite population. In the first test, Plictran gave the longest residual activity. At 1 week posttreatment, all rates of Mavrik, Omite, and Plictran had significantly reduced densities of adult mites compared with those of the check. By 2 weeks posttreatment, only Plictran continued to show significant reduction in density of adult mites. At 1 week posttreatment, Plictran and both rates of FMC54800 significantly reduced densities of eggs and adult mites. By 2 weeks posttreatment, mite density in check trees had dropped to that of treated trees. Mite predator populations were insignificant in all trees sampled.


: In this paper, first, using a test set on a turbocharged diesel engine in the engine test room, a nonlinear model is obtained and it is linearized around several operation points. Then, for the linear models, a linear quadratic integral Gaussian controller (LQIG) with variable parameters as function of engine speed is designed and simulated. In the proposed method, by controlling the wastegate, the boost produced by the turbocharger can be controlled at all engine speeds (especially the lower and middle speeds) with high performance response, thereby improving the output power and engine torque in all speeds. The closed loop control system is simulated and evaluated in the presence of noise and model uncertainty. The simulation results show the better performance and higher robustness in comparison with PID and LQR controllers.

The purpose of this study is to define the similarities and differences of the educational supervision systems of the developing countries and developed countries by comparing them and in Turkey, as a developing country, to define the situation of the educational supervision and also to make some recommendations about how it should be. In this study, the educational supervision systems of France, England, Germany, Finland, South Africa, Poland, Iran, India and Turkey have been analyzed and compared. As a result,, it is seen that Turkey, France, South Africa and Iran have more centralized supervision systems than the other countries. In Germany and Finland the autonomous structures of the schools are easily seen. England prefers a professional support from outside, thus, it is provided that schools can act more freely. Other striking point in developed countries is the faith in teachers and their skills. According to the developing levels of the countries, it is seen that in developing countries mostly it is focused on defining the inadequacy and finding mistakes. Recently there have been many changes on educational supervision system in Turkey. The most striking point is that there is an effort to foreground the intra-school supervision system. In order to increase the quality of the education in Turkey, the intra-school supervision system must be strengthen and also teachers must be included  into this process and approach of guidance must be improved.

This article suggests a few hypotheses to understand the new electoral configuration that was formed in 2006. The subproletariat, that has always kept itself away from Lula, accepted in large scale his candidature after the first term of his presidency, at the same time that the middle-class moved away from it. The explanation would be on a new ideological configuration, that mixes leftwing and rightwing elements. The rhetoric and the praxis, that are able to unite the maintenance of stability and the distributive action of the state, are in the origins of the formation of lulism.

Solid solution BiFe1-xCoxO3 shows anti-ferromagnetic order and pyroelectric order, simultaneously. It has been known that BiFe1-xCoxO3 exhibits a structural phase transition between monoclinic and tetragonal phases as x increases. This kinds of transition is often called morphotoropic phase boundary, which is well known to take place in a representative piezoelectric oxide, PbZr1-xTixO3. In order to theoretically understand the piezoelectric property in BiFe1-xCoxO3, we performed ab-initio electronic-structure calculations and studied the structural stability, the magnetic property, and the electronic polarization by means of super-cell approach. It turns out that the large electric polarization and the particular pyramidal coordination suppress the response of the electric polarization under strain. A way to enhance the piezoelectric effect in BiFe1-xCoxO3 is proposed.


This paper presents an effective unsupervised sparse feature learning algorithm to train deep convolutional networks on hyperspectral images. Deep convolutional hierarchical representations are learned and then used for pixel classification. Features in lower layers present less abstract representations of data, while higher layers represent more abstract and complex characteristics. We successfully illustrate the performance of the extracted representations in a challenging AVIRIS hyperspectral image classification problem, compared to standard dimensionality reduction methods like principal component analysis (PCA) and its kernel counterpart (kPCA). The proposed method largely outperforms the previous state-of-the-art results on the same experimental setting. Results show that single layer networks can extract powerful discriminative features only when the receptive field accounts for neighboring pixels. Regarding the deep architecture, we can conclude that: (1) additional layers in a deep architecture significantly improve the performance w.r.t. single layer variants; (2) the max-pooling step in each layer is mandatory to achieve satisfactory results; and (3) the performance gain w.r.t. the number of layers is upper bounded, since the spatial resolution is reduced at each pooling, resulting in too spatially coarse output features.


The magnetic properties and magnetocaloric effect (MCE) of NdCo2B2 were investigated by magnetization and heat capacity measurements. The compound exhibits a paramagnetic to ferromagnetic transition at TC = 27 K. The effective magnetic moment is 3.53 μB/Nd atom, and the magnetic ground state of Nd ion forms a doublet state in NdCo2B2. A large reversible MCE was observed, which is related to a second-order magnetic transition from the paramagnetic to the ferromagnetic state. The values of maximum magnetic entropy change ( ) reach 4.5 and 8.3 J kg−1 K−1 for field changes of 20 and 70 kOe without obvious hysteresis loss in the vicinity of the Curie temperature, respectively. The corresponding maximum adiabatic temperature changes ( ) are evaluated to be 3.3 and 6.9 K.


Metallation of the methyl group in 2-neopentylpyridine occurs with palladium(II) acetate to afford a novel six-membered cyclopalladated complex [{[graphic omitted])(O2CMe)}2]. This complex is readily converted into the chloro-bridged analogue, [{[graphic omitted])Cl}2], by metathetical reaction with LiCl. The chloro-bridged complex undergoes bridge-splitting reactions with 3,5-dimethylpyridine and thallium(I) acetylacetonate to give the corresponding mononuclear cyclopalladated complexes. All the complexes are characterized by means of elemental analysis and i.r. and 1H n.m.r. spectroscopy. The inversion of the six-membered chelate ring in these complexes is discussed on the basis of temperature-dependent 1H n.m.r. spectra.


Influential factors to the detectivity of n-CMT grown by liquid phase epitaxy on CdTe(111)B substrate are investigated. The factors are such as qualities of the substratesdopants and electrical parameters by which photoconductivity in CMT is governed. We show that the doping with small amounts of In is an appropriate mean not only to raise the mobility but also to make reproductivity better. The In- doped epitagia�r after annealed has the highest mobility among tested in 3×10 cm 5 /Vsec, and the photoconductive lifetime in 0.54 μsec at 77K.The resultant detectivity of an infrared device is 3×10 10 cmHz 1/2 w −1 .

to glorify or idealize the war and uses the veterans' own memories to reconstruct the world of a combat soldier; he does not sugarcoat the actions or emotions of the 99ers but bluntly relays their memories and their journey. In this way, the wastefulness, animalism, and emotional turbulence that the war created become apparent to readers, and the book portrays a sometimes brutally honest depiction of the war and the men who fought it. In doing so, this narrative provides a window for readers to appreciate the challenges that combat soldiers faced, and through that window many will come to admire their strength and perseverance.


Abundances and excitation temperatures of metals in the low chromosphere were detertmined as functions of height using the 1962 eclipse data of the joint expedition of HAO and SPO, without the assumptions of local thermodynamic equilibrium and a constant source function. Lower term densities were determined from the self-absorption of flash lines, and estimations were made for the abundances of iron, titanium, chromium, scandium, strontium, barium, and zirconiunn. Excitation temperatures for most of the lines are shown to be decreasing in the outer regions of the atmosphere, but those for some of the lines exhibit the opposite behavior. Relative abundances of metallic elements in the upper layer seem to be the same as the photospheric values, but those abundances relative to hydrogen are increasing with height. It is likely that those apparent differences of relative abundances between the upper and lower layers originate from inhomogeneties in the chromosphere. (auth)


This paper explores the utility, from the viewpoint of anti-violence centre workers, of integrating biographical research with the services already offered. Because of the intent of the biographical approach to capture forms of self-representation in context, the integration proposal is configured as a tool hypothetically useful in the personalization of interventions, but also as a reflective resource for women victims of violence, responding to the need for the recall, ordering and re-signification of events experienced/narrated. To test the action-research hypothesis, a focus group of professionals at the Maree Anti-Violence Centre was organized to favor the frameworks, conceptual schemes and practices of those who work daily in direct contact with women victims of violence. The research findings, in addition to the utility and sustainability of the proposal, suggest a combination of the biographical approach with observation techniques to illuminate relational and fictional strategies along with shadowy areas of the narrations. Keywords: anti-violence centres, gender violence, biographical approach, action-research, observation


This special issue will consider issues around women's movements, everyday sexism and the 'blurred lines' of social media. Social media are highly interactive digital platforms that use mobile and web-based technologies to allow users to generate, share, discuss, and modify content (e.g., YouTube, Facebook, Twitter, Instagram). Whilst feminisms and social media are transdisciplinary spaces, this issue will contribute to a body of psychological theory and will be of interest to psychologists as well as other social scientists. Taking as the backdrop the claims that a 'new' feminism and a 'new' misogyny are both rife over social media the proposed special issue brings together papers to consider a number of contemporary issues that are coming to the fore around gender and social media. Social media provides different challenges to issues such as what it means to be a feminist in the 21st century and the new concerns facing women in an era marked by technological advances. Indeed, whilst social media platforms can be a social force for activism (e.g. the Arab 'spring') they also raises questions about how discussions of gender through social media 'evoke' public censure and commentary.

rest. The characteristic vomit continued to recur at much longer intervals. Occasionally the rejected material was merely a greenish fluid, consisting, no doubt, of the water swallowed mixed with bile. The symptoms were now less acute, but distension increased. Warm fomentations were constantly applied, and injections given occasionally. On the third day she was seen in consultation by Dr. Ridley of Gateshead, who suggested operative means, or at least tapping, for the purpose of relieving the tympanites, which was now becoming extreme, and that possibly the bowel might right itself. Her friends, however, were averse to any form of surgical interference; and the treatment was continued as hitherto, with the addition of nutritive enemata, and the free use of belladonna liniment to the abdomen, as recommended by Dr. Ridley. The opiate maintained its soothing influence, but the symptoms became more urgent. Hiccough was constant in the evening; tongue red and dry; pulse 134; temperature not taken. She had another good night, and in the morning looked decidedly better than on the previous evening. She had two attacks of fncal vomiting during the day, but rested well. It was now the fifth morning, and the last upon which sickness and stercoraceous vomit appeared. Her pulse was good, and her expression cheerful. In the afternoon she informed me that "1 something had liberated itself in her inside," and that she was passing wind since I saw her last. A liquid motion followed soon after from the bowels, which contained a few firmer pieces of freces of the size of hazel-nuts. From this date, her improvement was uninterrupted. She soon regained her usual health, and has since remained perfectly well.

If this were a case in point, the favourable result was probably due to the free use of opium. Had purgatives been used, fatal strangulation would, I think, have inevitably supervened.

Destroying the human body through immersing it in a commercially available acid to avoid identification has become more popular today. Forensic odontology can help aid in the identification of an individual. Teeth are the most durable of all tissues because they are preserved after other skeletal structures are destroyed. The purpose of this research is to identify the commercially available acid that may be used for destruction of a human body. The significance of this research is that it will aid forensic scientists to determine what commercially available acid is the most common for criminals to use when destroying a body. During this study, the morphological changes in human teeth will be observed when they are kept immersed in an acid. The commercial acids being used are 37% hydrochloric acid (HCl), 65% nitric acid (HNO3), and 96% sulphuric acid (H2SO4). This research will include six anterior canine human teeth. The teeth are immersed separately in different beakers containing the different acids and observed at various intervals. The tooth will be examined for any changes, photographed, then placed back into the respecting container. The tooth will be observed until it has completely dissolved. The results concluded that teeth were completely dissolved in 37% hydrochloric acid and 65% nitric acid within 48 hours. Teeth immersed in 96% sulphuric reacted differently, not completely dissolved but transforming into a white precipitate. The teeth remained intact until 192 hours, when only white precipitation remained. The results showed that 37% hydrochloric acid and 65% nitric acid dissolved the teeth in the most effectively compared to 96% sulphuric acid. The morphological changes observed can also be used to determine time duration for teeth immersed in acids.


The magnetic semiconductor in a two-dimensional system is a major subject for both theoretical and experimental investigations. Here we report the synthesis of a new quaternary manganese chalcogenide KMnCuTe2, which shows layered structure and antiferromagnetic (AFM) semiconducting features. Single crystals of KMnCuTe2 were obtained using a self-flux method and based on single-crystal X-ray diffraction, KMnCuTe2 adopts the ThCr2Si2-type structure composed of edge-sharing tetrahedral layers separated by K+ cations. The Mn and Cu atoms randomly distribute in the centre of tetrahedral units. Attributed to the large radius of Te, KMnCuTe2 has large lattice parameters (a = 4.3115(3) Å and c = 14.9360(20) Å), leading to a long metal–metal distance (3.049 Å) in the tetrahedral layers. Based on the experiments and theoretical calculations, KMnCuTe2 exhibits a G-type AFM interaction with the transition temperature at around 225 K and an indirect semiconducting nature with the band gap of 0.95 eV. The magnetic semiconducting property of KMnCuTe2 is unique in AMnMCh2 systems (A = Li, Na, K, M = Cu, Ag and Ch = S, Se, Te), which could be associated with the large metal–metal distance. Our work not only highlights the role of metal–metal interactions on regulating the properties of ThCr2Si2-type compounds, but also provides a feasible strategy to obtain the layered magnetic semiconductor.

How far regional policy incentives support the development needs of the financial services sector is examined. In reviewing the changing eligibility of financial services in UK regional policy, it is argued that the sector has been increasingly recognized as important in regional development. However, when examining the usage of incentives among Scottish financial services companies, incentives appear to have only limited relevance. The different needs of services and manufacturing firms suggest that incentives would be more effective if they targeted "soft" investments and were supplemented through the use of other, non-incentive, regional policy measures.


Defining the cancer genome is essential for understanding the pathogenesis, but it remains challenging due to the paucity of robust models for characterizing recurrent mutations found in cancer. To understand the molecular mechanisms underlying the development of small-cell lung cancer (SCLC), an aggressive type of lung cancer initiated by inactivation of both RB and P53, it is important to determine the functional impact of recurrent mutations found in the patient tumors. To this end, we developed a somatic engineering approach, using a CRISPR/Cre hybrid tool that expresses guide RNA, Cas9 endonuclease, and Cre recombinase from a single adenoviral vector (Ad-target of gRNA-CRISPR/Cre). Intratracheal instillation of this recombinant virus causes mutation in a candidate tumor suppressor gene while recombining floxed alleles of Rb1, Trp53, and Rbl2 in the same epithelial cell. To determine functions of Ep300, Slit2, and Fhit, whose orthologous genes are frequently mutated in SCLC patient tumors, we infect the Rb1/Trp53/Rbl2 conditional mice with the viral vectors carrying gRNAs against these genes. The mice infected with Ad-Ep300-CRISPR/Cre or Ad-Fhit-CRISPR/Cre have higher tumor burden in the lungs than those infected with Ad-lacZ-CRISPR/Cre used as control. Although Slit2 is significantly mutated in SCLC, the mice infected with Ad-Slit2-CRISPR/Cre do not increase tumor burden relative to those with Ad-lacZ-CRISPR/Cre. These results for the first time validate the oncogenic impact of Ep300 and Fhit mutations. This study demonstrates the feasibility and robustness of a new somatic engineering-based model for characterizing candidate mutations, which will facilitate the discovery of key oncogenic drivers and pathways from the large number of novel somatic alterations in SCLC. Ongoing efforts with this new approach are focused on validation of functionally unknown mutations alone or in combinations. This abstract is also being presented as Poster A39.

In this study, we focused on the molten salt method and attempted a simple synthesis of SrTi[Formula: see text]Co[Formula: see text]O3. It was clarified that SrTi[Formula: see text]Co[Formula: see text]O3 can be obtained under relatively mild conditions by using the molten salt. In all samples, the electrical conductivity increased with increasing temperature. Compared with the sample without the molten salt, the electric conductivity of the samples with the molten salt was greatly improved. The sample using the KCl-NaCl mixed salt showed the highest electrical conductivity of 83 S/cm at 973 K. The relative densities of all the samples using the molten salt were above 85%. It is considered that the improvement in the electrical conductivity is partly due to the increase in the relative density.


The present study is an attempt to demonstrate and stress upon the complexity characterizing the way in which Anatol Vieru - a representative composer for the Romanian musical vanguard - through the organization of the initial available sound material resources on principles of horizontal and/or vertical symmetry (typical to non-gravitational harmony), manages to create in Symphony no. 5 "Peste varfuri", a cycle of 48 Variations reunited under the form of an original chaconne - a true model of the genre, starting from a modal-harmonic algorithm with polychordal structure - with double functionality: that of an unique generative source of the sound matter and also, of a perpetuum obsessively extended throughout the entire variational cycle.


It appears somewhat ironic that the Government demands that our agricultural industries compete internationally on a level playing field, while here in our own back yard, MIS's have effectively created specific domestic subsidies. As a result the Australian Tax payer has indirectly made significant contributions to fund enterprises managed by MIS promoters. To date, the private plantation forestry sector has been the primary beneficiary of such government funding.


Summary In summer 1987, 584 students at Oxford University were sent a questionnaire enquiring about their sexual behaviour and contraceptive practice, and about the effect that AIDS has had on these. Of the 374 students who replied, 65% of the women and 62% of the men had experienced sexual intercourse. Twenty-seven per cent of female undergraduates did not use adequate contraception on the first occasion of intercourse. During the 4-week period preceding the questionnaire, 15% of sexually active female undergraduates did not use adequate contraception. The use of contraception has changed over the last 5 years, with fewer students using oral contraceptives as their most frequent means of contraception and more using barrier methods. In general, knowledge about AIDS was high. Most students did not consider that they were at risk of becoming infected by the AIDS virus and, by their reported sexual behaviour, very few students appeared to be at any risk. However, 35% of women and 44% of men who were sexually active said that because of risk of AIDS they had been more likely to use the sheath, and 49% of women and 30% of men said that they had, or would have, fewer partners. These findings suggest that attitudes, and possibly behaviour, are changing towards a reduction in risks of sexually transmitted infection.


The accuracy of QRS detection and premature ventricular beat (PVB) recognition by an on-line computer system was evaluated in a prospective study. Long-term studies in six cardiac patients and short term studies in thirty revealed a QRS detection accuracy of 99%. PVB accuracy was tested in twenty-eight patients for a total time of 415 minutes. About 10% of the heart beats in this group were recognized as PVBs by the cardiologist; 90% of these were correctly identified by the computer system. False positive PVBs were less than 1% of the PVBs. The major types of PVBs missed were fusion beats and late PVBs. Some were unrecognized because of coincident excessive movement artifact. The computer system appeared to be sufficiently reliable to warrant further clinical studies.


High-resolution solar spectroscopy provides a wealth of information from photospheric and chromospheric spectral lines. However, the volume of data easily exceeds hundreds of millions of spectra on a single observation day. Therefore, methods are needed to identify spectral signatures of interest in multidimensional data sets. Background-subtracted activity maps (BaSAMs) have previously been used to locate features of solar activity in time series of images and filtergrams. This research note shows how this method can be extended and adapted to spectral data.


This chapter provides a summarized and objective re iew over the relationships among innovation, socia l innovation, entrepreneurship, social entrepreneursh ip, new business models (NBM), and product (good, service, idea) value and sustainability (economic, social, ecological, and psychological). A study has been done in Porto region through interviews with 13 soc ial innovators and entrepreneurs, in order to evalu ate those relationships. The conceptual base for analys is is the theories developed by Jonker (2012) and Carvalho & Jonker (2015). It has been concluded tha t m rket-oriented social innovation has a crucial r ole in the development social entrepreneurship. Moreove r, th se NBM should be adjusted to population needs towards societal well-being, by combining creation of shared value, co-creation of value, and multiple value creation. Thus, the value set (social innovat i n) contributes to economic, social, ecological, a nd psychological sustainability, and consequently to h uman, social and territorial development.


Research objective. To experimentally ground the technological approaches to evaluating training effects of primary schoolers' power loads. Materials and methods. To achieve the objectives outlined, the research used the following methods: analysis of scientific and methodological literature, pedagogical testing, modeling, pedagogical observation and experiment, methods of mathematical experiment planning (complete factorial experiment, 2 k type), discriminant analysis. The participants in the study were 32 second grade boys. Research results. The training pattern affects the dynamics in the test results for the second grade boys. The test results can improve provided that the power load brings about significant changes after the training at each spot, after the training (immediate training effect), and twenty four hours after the power load (delayed training effect). The higher the dynamics is for the immediate and delayed training effects, the more significant are the improved power tests results observed after as few as three lessons. Conclusions. The discriminant function can be used to classify the training effects of the second grade boys' power loads. The first canonical function explains the results variation by 85.0%, the second one — by 14.0%. This suggests that they are highly informative. The centroid coordinates for five groups allow to interpret the canonical functions according to the role differentiating the grades by the training effects of the primary schoolers' power loads. The positive pole of the first function has the condition centroids at the beginning of the power loads, after three, six, nine and twelve lessons; the negative pole has the centroids of the training effects after the power loads, after the lesson, after 24 hours. Thus, the reaction to the power load has immediate, delayed and cumulative training effects.


This paper explains how to identify organic food buyers in Australia and what products they purchase. Data was gathered via interviews with 20 food buyers and a descriptive survey using a questionnaire distributed to 1000 households in one region in Australia with 300 responses. Approximately 40% of all food buyers purchased organic food although its market share is less than 1%. As organic food buyers are difficult to identify from a demographic perspective, promotion of organic food should identify perceived health, quality and environment attributes.


The machine learning method, random forest (RF), is applied in order to derive biophysical and structural vegetation parameters from hyperspectral signatures. Hyperspectral data are, among other things, characterized by their high dimensionality and autocorrelation. Common multivariate regression approaches, which usually include only a limited number of spectral indices as predictors, do not make full use of the available information. In contrast, machine learning methods, such as RF, are supposed to be better suited to extract information on vegetation status. First, vegetation parameters are extracted from hyperspectral signatures simulated with the radiative transfer model, PROSAIL. Second, the transferability of these results with respect to laboratory and field measurements is investigated. In situ observations of plant physiological parameters and corresponding spectra are gathered in the laboratory for summer barley (Hordeum vulgare). Field in situ measurements focus on winter crops over several growing seasons. Chlorophyll content, Leaf Area Index and phenological growth stages are derived from simulated and measured spectra. RF performs very robustly and with a very high accuracy on PROSAIL

Using Landsat image data from NASA satellite, dating back to 1972, Hayden and LeCompte et al. (2013) established grounding line, a boundary between disintegrating floating ice shelf and the ground ice that feeds it in Amundsen Sea. This project improved significantly our knowledge of cryospheric processes by comparing 30 years of record from 1972 to 2003. Pine Island located south of Larsen, equivalent to the size of twothirds of UK, is a key study site of Elizabeth City State University's Center of Excellence for Remote Sensing Education and Research (CERSER). This study proved the break-up of Larsen A ice-shelf in 1995 and Larsen B ice-shelf in 2002. The warming of the waters off Western Antarctic Peninsula (WAP) has influenced density and distribution of the Antarctic Krill Euphausia superba. Fevolden and George (1984) established the size frequency patterns of E. superba in WAP in the austral summer of 1983. In 2009-2010, Bernard et al (2011) provided evidence to conclude WAP is a region of rapid climate change that altered plankton community structure, suggesting ecosystem-evolution in some pats of Southern Ocean. While E. superba is a major grazer in the coastal regions of WAP, Salpa thomsoni dominated grazing offshore. E. superba will likely become less dominant if pteropod Limacnia helicina and Salpa thomsoni expand their ranges in WAP region. Krill distribution and abundance also depends on primary production in the preceding years. George (1984 and 2016) reported that krill egg development is influenced by temperature, pressure and pH. Potential collapse of Antarctic krill E.superba may not occur in 2100 with atmospheric CO2 at 770 ppm, as hypothesized by Kawaguchi et al (2013) but eggs of pteropod Limacina helicina antarctica may become far more susceptible with atmospheric CO2 reaching 770 ppm since 80% of pteropod eggs failed to undergo organogenesis (Manno et al., 2016).

Quebec author Jovette Marchessault's play about the British Columbian artist Emily Carr draws from Carr's paintings and autobiographical writings in order to capture the essence of her art and to provide a compelling interpretation of this fascinating personality and the social and familial pressures under which she worked. The extraordinary synergism between Emily's magnificent voyage and Jovette's own literary, artistic, and spiritual trajectory constitute the focus of this essay. The points of convergence between the artistic and literary production of the two women are analyzed with emphasis on the supernatural and Amerindian influences found in Emily's paintings and in Jovette's writings.


This paper reports the results of a computational study that was conducted to explore the effect of various Variable Camber Continuous Trailing Edge Flap (VCCTEF) configurations on the lift and drag of a NASA Generic Transport Model (GTM) wing section at a span-wise location called the break station that marks a sharp change in the wing trailing edge slope. The OVERFLOW solver with the the one-equation SpalartAllmaras (SA) turbulence model and the two-equation (k − ω) Shear Stress Transport (SST) turbulence model was first applied to a NACA0021 airfoil case and the results were compared with experimental data of Harris and ARC2D results. The comparison showed good agreement between earlier results and the SA model. Therefore, SA model was used for all the simulations in this study. Design cruise condition at 36,000 feet at free stream Mach number of 0.797 and Reynolds number of 30.734x10 was simulated for an angle of attack (AoA) sweep from -3 deg. to 10 deg. Five VCCTEF configurations with varying camber in the flap region were considered along with an unmodified (no flap deflection) airfoil as the baseline case. Comparison of lift and drag corresponding to these configurations with baseline configuration (retracted flaps) showed a definite trend in the results. Although the baseline configuration produced the lowest lift at a given AoA among the set under investigation, it produces stall after about 5 deg AoA, whereas with the VCCTEF settings, stall occurs earlier between 3 and 4 deg AoA. The lift enhancement was significant with the extended flaps, but it was accompanied with a drag penalty, as expected. But, the lift versus drag L/D results showed that at the design cruise lift coefficient of 0.51, the L/D characteristics improved from the baseline to four of the five VCCTEF configurations. Among these four configurations, the configuration which reflects a parabolic-like camber is more optimal than the other three configurations in terms of improved L/D and well-behaved Cp distribution. The lift prediction is compared against theoretical lift prediction from potential flow theory. Excellent agreement between computed and theoretical incremental lift is shown.

Polarization sensitive Fourier domain optical coherence tomography (PS-FD-OCT) using fiber components with continuous polarization modulation is demonstrated. The incident polarized light is modulated by electro-optic modulator (EO modulator) synchronized with lateral B-scanning. By the incident polarization modulation and the polarization sensitive spectrometer, the depth-resolved Jones matrix image of biological sample can be measured. This method uses both polarization modulation method and Fourier transform method. In this paper, the algorithm is described and the phase retardation image of chicken breast muscle is measured.


An experimental study for isotropic pitch materials prepared from cracking oil residues has been carried out to clarify the Theological properties in the molten state. The softening point, thermal expansion coefficient, viscosity and the viscoelastic moduli were measured. The aromatization index of the isotropic pitches was estimated from the element analysis (C and H), density, and the NMR measurements. The activation energy for shear flow which was estimated from the temperature dependence (100°C to 150°C) of the steady shear viscosity was 40 kcal/mol. The softening points, thermal expansion coefficient and the activation energy were correlated to the aromatization index. The steady state shear viscosity was described to be proportional to the molecular weight with the 40th power. The frequency dependences of the dynamic moduli were similar to those of monodisperse linear polymers.

Safety requirement represents one of the most critical aspect when defining the operational profile for a RendezVous mission. This requirement specially affects the design of the guidance algorithms that need to be tailored to guarantee what is normally referred to as "Passive Trajectory Protection". The basic idea of passive trajectory protection is to design all the trajectory elements in an approach sequence such that if, at any point of the trajectory, thrust control ceases, the resulting free drift motion will remain collision free during a certain amount of time. This paper deals with the design and performances assessment of specific guidance algorithm addressing this issue. Firstly the problem is addressed for circular orbit using the "Traveling Ellipse" formulation for the relative motion. Secondly a solution for the RendezVous into a generic elliptical orbit is presented. This is based on a reduced transition matrix obtained through a description of the relative motion based on the first order variation of the orbital elements.

: Since ancient times, river basins are often rich in land and water resources, so they have become key socio-economic regions of countries around the world. In these areas, the development of economic and social sectors has significantly changed and increased the demand for water throughout the region, putting pressure on sustainable planning and management of water resources. this limited natural resource. In addition, under the impact of climate change (CC), available water resources are expected to have abnormal changes. Therefore, the calculation and assessment of water use needs of water-using industries will help managers have an overview of the current situation and future water use requirements to serve as a basis for the water industry. Planning and management of water resources is a key factor for sustainable socio-economic development of the whole region. This study uses the detailed climate change scenario data of the global forecasting model MPI-ESM-MR, MPI-ESM-LR, HadGEM2-ES và NorESM1-M for up to 13 water use subdivisions in the Red River Delta (Red River Delta) of quantitative factors. Rain, temperature, combined with data, statistics on population, agriculture, industry, fisheries, livestock of provinces in the region to serve to calculate the demand of water-using industries in the period. status quo and forecast in 2030, with a vision to 2050. Calculation results show that the total water demand of the whole Red River Delta in 2020 is approximately 13.118 billion m 3 , in 2030 is approximately 14,523 billion m 3 , by 2050 it will be about 14,307 billion m 3 . Water demand in the future tends to decrease. However, compared with the period of 2020-2030, the water demand for the period of 2030-2050 for agriculture and aquaculture tends to decrease, while the demand for domestic use and industry increases.


A 3-Dimensional (3-D) CMOS integration with a structure, in which one type of transistor is fabricated directly above a transistor of the opposite type with separate gates and an insulator in between, has successfully been fabricated by using laser beam recrystallization. Seven-stage ring oscillators fabricated in the 3-D structure have a propagation delay of 430psec per stage at a supply voltage of 5V, which is comparable to that of single-crystal Si devices. This CMOS structure and the process technologies we have developed in this work can be the basis for realizing a multi-layered 3-D integration composed of vertically stacked transistors with separate gates and an insulating layer in between.


This paper investigates patterns of rhetorical convergence and divergence in pairs of RA abstracts (English-Spanish and Spanish-English) published in the journal Iberica. To that end, a total of 84 pairs of author-translated RA abstracts were analyzed. Based on the results of a pilot study, the following rhetorical patterns were analyzed in the corpus: text-referring expressions, degree of epistemic commitment, amplified attitude, self-mention, and periphrastic (e.g. multi-word) expressions. In addition, selected authorial input was requested to seek further explanations about the variation across these two languages. For text-referring expressions, broad cross-linguistic convergence was found in the expressions used and the degree to which the text is given agency. By contrast, the abstracts in Spanish were found to include greater degree of epistemic commitment, more amplified expressions of attitude, more self-mention, particularly in the plural first person, and periphrastic equivalents. Authorial input indicated that some of these diverging patterns were due to collocational differences but they were also influenced by beliefs about what is more natural in Spanish. Our results suggest that there may be specific lexical bundles performing intensifying functions in Spanish that deserve further investigation. These findings may have implications for ESP pedagogy and translation studies.


We analyse same sign dilepton signatures in a non-universal flavor changing Z' model. These arise due to tt (or t_bar t_bar) production processes due to the semi-leptonic decays of (anti)tops. We also discuss top reconstruction and spin measurement using the variable MT2 and MT2-Assisted On-Shell (MAOS) Momentum} techniques and will also provide a comparison with the on-shell mass relation method. Sensitivities to the flavor-changing top coupling has also been estimated for different LHC energies and projected LHC luminosities corresponding to them.


The authors model the politics of wage and employment determination for unionized public-sector workers who can strike. If the employment level affects the identity of the decisive voter in budget referenda and other elections, then unions may be able to increase wages by increasing employment. The authors identify conditions under which public-sector unionization will lead to increased wages and employment; they also show that a majority of voters may favor unionization.

In this document we present a method by which we can extend the usable frequency range of a coaxial line into a region where higher order modes would normally propagate. We describe a complete method for designing the periodic ring structure and provide a model which is capable of predicting the dispersion of the (Q)TEM modes propagating in the transmission line. Moreover, all important cut-off frequencies are addressed to enable the engineer to take full control of the branches of higher order modes in the targeted frequency scale. With the help of full-wave simulations we verify our theoretical models and show that a good matching can be achieved when connecting the proposed structure to a conventional transmission line.


Over the past few decades the volume of research on adolescent health has grown considerably. A number of national reports have been issued that summarize research findings and make recommendations regarding directions for future research. The current project synthesizes the recommendations in these reports to provide a collective assessment of the state-of-the-science in adolescent health research. By synthesizing broad-based trends in research priorities for adolescent health this report identifies gaps in the existing knowledge base understudied populations underutilized research approaches and essential resource needs. Findings from this analysis can help to inform future science policy by providing options for an adolescent health research agenda as well as a benchmark for assessing current science policy and funding priorities.

The invention relates to a method for producing a biological particle grain-saving straw feed, effectively solving the problem of grain waste in the production of a biological particle straw feed so as to meet the need of stockbreeding on feeds. The method comprises the following steps of: firstly, mixing the raw materials in percentage by weight: 70-80 percent of straws, 17-27 percent of corn meal, 0.5-1 percent of ammonium bicarbonate, 0.2-0.4 percent of brown sugar, 0.5-1 percent of active biochemical bacterium and 0.4-0.6 percent of common salt; adding 45-55 percent by the raw material weight of water at 24-30 DEG C and uniformly stirring and mixing; and then, putting in a sterile workshop at 40-44 DEG C, carrying out anaerobic fermentation for 6-8 days, extruding to remove 30-40 percent of water content to form a fermented raw material and then granulating and air-drying. The method provided by the invention is simple, rich in raw materials and easy to produce, can fully utilize biological straws and save grains, has good feeding effect and remarkable economic and social benefits and therefore is a great innovation on the biological feed.


This paper addresses the problem of asymptotic trajectory tracking with prescribed transient behavior for a fully actuated marine surface vessel subject to unmodeled dynamics and external disturbances. A prescribed transient performance constraint is introduced to specify the transient behavior of the output tracking errors. Neural network (NN) approximation and adaptive control techniques are employed to compensate for the unmodeled dynamics. In general, the NN approximation errors always exist in the NN-based adaptive control systems, and typically result in uniformly ultimate boundedness, where the tracking errors cannot be stabilized asymptotically. In order to obtain an asymptotic tracking performance, a robust integral of the sign of the error (RISE) feedback term is introduced in feedback control design to compensate for the NN approximation errors and external disturbances. Consequently, RISE-based adaptive NN controller with compensations of unmodeled dynamics and external disturbances is proposed such that an asymptotic tracking performance is achieved with guaranteeing prescribed transient behavior. The performance of the proposed tracking controller is shown by simulation results.


Dietary intakes were obtained by 24-hour recall from 25 women in the 1st and 3rd trimesters of pregnancy and from 25 women during their 1st 3 months of lactation from 8 towns in the Amazon valley. No consistent differences were found between the towns and therefore the results have been analyzed together. Intakes of iron free and total folate and zinc were nearly all very low intakes the majority of the women had acceptable values of hemoglobin hematocrit and MCHC. Serum folate concentrations were almost all extremely low ( < 2.5 ng/ml). The levels of RBC folate were also low but in general not as severely as those for serum folate. Serum zinc concentrations ranged from 0.2-0.7 mcg/ml whereas the lower limit of acceptability has been put by various authors as 0.59-0.69 mcg/ml according to the stage of pregnancy. In breastmilk total folate in the majority of women ranged from 25-50 ng/ml the greater portion of it being in its free form. Zinc levels in breastmilk were within the 0-2 mcg/ml range.

CD300e has been reported as either an activating or inhibitory receptor and is involved in the tuning of immune responses. In this study, we demonstrate that CD300e acts as a ligand through an unknown receptor to inhibit T cell immunity. In PBMCs, CD300e protein is expressed on the cell surface of CD14+ monocytes, but not on T and B cells. CD300e-Fc fusion protein significantly reduced the expression of CD69 and CD25 on T cells, which suggest that CD300e inhibits the activation of T cells. Furthermore, CD300e-Fc fusion protein significantly inhibited TCR-mediated T cell proliferation and cytokine production including IL-2, IFN-gamma, IL-17, TNF-alpha, IL-8 and IP-10/CXCL10. Florescent conjugated CD300e-Fc fusion protein significantly bound to activated T cells and weakly to inactive T cells, suggesting that the putative CD300e counter-receptor is expressed on the cell surface of T cells, and the expression levels are upregulated upon T cell activation. CD300e-Fc fusion protein inhibited TCR-mediated p38 MAPK phosphorylation which indicates that CD300e negatively regulates T cell activation by impairing the p38 MAPK dependent antigen presentation. Moreover, our results support the notion that CD300e might be a new player in the regulation of the expansion of T cell-mediated responses. This CD300e novel T cell inhibitory pathway may provide a new strategy to modulate T cell-mediated immunity to treat immune-related diseases.

What does ecological restoration mean in an urban context? More than half of the world's population now lives in cities, and in response to the dynamic patterns of urbanization, a growing number of ecologists, land managers, and volunteers are focusing their efforts in and around cities to restore remnants of natural diversity (Ingram 2008). Ecological restoration is still a quite youthful field, yet many scientists and practitioners hold a relatively fixed set of criteria for what defines a successful restoration project, irrespective of where sites are located.


Herein we report a case of a cardiac echinococcal cyst located in the interventricular septum and producing a mild obstruction of the left ventricular outflow tract. The cyst was detected by cross-sectional echocardiography and thoracic computed tomography and treated successfully with mebendazole.


Aims We conducted a simulated nitrogen (N) and sulfur (S) deposition experiment from 2006 to 2012 to answer the following questions: (i) does chronic N and S deposition decrease cation concentrations in the soil and foliage of understory plant species, and (ii) does chronic N and S deposition decrease plant diversity and alter species composition of the understory plant community in a boreal forest in western Canada where intensifying industrial activities are increasing N and S deposition? Methods Our field site was a mixedwood boreal forest stand located ~100 km southeast of Fort McMurray, Alberta, Canada. the experiment involved a 2 × 2 factorial design, with two levels each of N (0 and 30 kg N ha−1 yr−1; applied as NH4NO3) and S addition (0 and 30 kg S ha−1 yr−1; applied as Na2SO4). Four blocks were established in July 2006, each with four plots of 20 × 20 m randomly assigned to the treatments. Soil and understory vegetation were sampled and cover (%) of individual species of herb (height ≤ 0.5 m) and shrub (height 0.5–1 m) layers was determined in August 2012. Important Findings Seven years after the treatments began, N addition increased dissolved organic carbon and N in the mineral soil (P < 0.05), whereas S addition decreased exchangeable cations (P < 0.05) in the forest floor. In the shrub layer, species evenness, and overall diversity were decreased by N addition (P < 0.05) due to increases in abundance of nitrophilous species and S addition (P < 0.01) due to decreased cation concentrations in soils. total shrub cover decreased with S addition (P < 0.10). Nitrogen and S addition affected neither species richness nor evenness in the herb layer. However, permutational multivariate analysis of variance and non-metric multidimensional scaling analyses (based on plant cover) indicated that the effect of N and S addition on understory plant species composition in the both shrub and herb layers was species-specific. Addition of N decreased foliar phosphorus and potassium concentrations in some species, suggesting potential risk of N-meditated nutrient imbalance in those species. Our results indicate that long-term elevated levels of N and S deposition can negatively impact plant nutrition and decrease the diversity of the understory plant community in boreal forests in northern Alberta, Canada. However, considering that the current N and S deposition rates in northern Alberta are much lower than the rates used in this study, N and S deposition should not negatively affect plant diversity in the near future.


With the explosive growth of mobile devices, the computing power and resource storage of the mobile terminal have higher demand, and the workflow task scheduling in the moving edge computing environment can solve complex data dependencies between tasks in workflows. The proposal of moving edge computing techniques is to solve computing resources caused by massive mobile device access, which can meet the low delay and high computing power of the mobile device. This paper proposes a workflow task scheduling optimization algorithm (WTS-OSM) in moving edge computing environment. First, the workflow tasks are generated into directed acyclic graph (DAG), and then the tasks in DAG are layered. The tasks in the same layer do not have dependencies, but the tasks in two adjacent layers do. Finally, an optimized genetic algorithm (GA) is used to determine whether the layer task computes unloading. Experimental results show that the proposed algorithm is superior to the traditional algorithms in terms of the task execution time.


Based on X-ray diffraction and infrared spectroscopy measurements, BN thin films grown by PECVD on silicon substrates have been studied with the aim of identifying the thin film phase. In a set of samples, while the infrared spectra showed characteristic bands of the hexagonal phase, X - ray diffraction patterns only displayed reflections belonging to the cubic BN phase. Therefore, structural models have been developed to explain the apparent inconsistency between the two sets of experimental data. In particular, static disorder effects - which have been introduced in the model starting from the sp 2 hybridization of the ordered hexagonal phase, as suggested by the infra-red spectroscopy results - allowed a consistent interpretation of the X-ray diffraction patterns. For another set of samples, which also showed a characteristic hexagonal signal in the IR data, the XRD pattern could not be indexed with any of the BN phases. In this case, the presence of molecular and ionic phases, associated with impurities, was considered in structural modeling studies.


Hemodynamic optimization is a complex task requiring, among other things, monitoring of arterial and venous pressures, urine output, acid-base balance, and oxygen content/delivery. These parameters, however, reflect the overall circulatory state and not the basic physiologic determinants of cardiac output (CO), which include preload, afterload, and contractility. To help determining these basic physiologic determinants, the pulmonary artery catheter (PAC) has been used by clinicians for almost 4 decades where it became the mainstay of patient monitoring in the operating room and in the intensive care unit (ICU) setting. It provides direct information on pressure variables such as pulmonary artery pressure, pulmonary artery occlusion pressure, and central venous pressure. It can also provide flow-related data such as CO and mixed venous oxygen saturation. Despite its extensive use, the clinical value of data obtained from pulmonary artery catheters remains unproven. Therefore, an alternative approach to the PAC monitoring has been proposed—the functional hemodynamic monitoring. This approach focuses on the effects of positive pressure ventilation on left ventricular (LV) output; positive pressure ventilation induces phasic changes in LV stroke volume through similar cyclic changes in venous return. This is a ''normal'' phenomenon for all patients ventilated with positive pressure ventilation, and can be advantageous in situations of hypovolemia.


Sulfur/carbon composite was synthesized by the thermal method with the carbon xerogel as the conductive framework. The property of composite was characterd by XRD and SEM. It shown that the composite with the particle size below 10 μm had the same morphology as the carbon xerogel and the sulfur was absorbed in the pores in non-crystalline. The discharge capacity of the composites were 1311 mAh/g and 1107. 1 mAh/g at 0. 1C and 0. 2 C rates,respetively. And a retention capacity was about 800 mAh/g after 30 cylcyes.


Many theories of dark matter (DM) predict that DM particles can be captured by stars via scattering on ordinary matter. They subsequently condense into a DM core close to the center of the star and eventually annihilate. In this work, we trace DM capture and annihilation rates throughout the life of a massive star and show that this evolution culminates in an intense annihilation burst coincident with the death of the star in a core collapse supernova. The reason is that, along with the stellar interior, also its DM core heats up and contracts, so that the DM density increases rapidly during the final stages of stellar evolution. We argue that, counterintuitively, the annihilation burst is more intense if DM annihilation is a $p$-wave process than for $s$-wave annihilation because in the former case, more DM particles survive until the supernova. If among the DM annihilation products are particles like dark photons that can escape the exploding star and decay to Standard Model particles later, the annihilation burst results in a flash of gamma rays accompanying the supernova. For a galactic supernova, this "dark gamma ray burst" may be observable in CTA.

In the previous chapter, the concept of social exclusion, typologies and indicators in the Indian context are examined. The theoretical application of the concept in the Indian context, where exclusion does not depends on the individual attributes but significantly attached to the social factors that are attributed to individuals, will further improve our understanding of the social exclusion. Thus, the purpose of this chapter is to examine how economic interpretation of caste system and its consequences are applied especially in the Indian context on the basis of writings of Sukhadeo Thorat on the same. This chapter is divided into six sections. In the second section, we discuss the economic interpretation of caste system and economic theories of caste. In section three, major features of the caste system are discussed following dynamics of caste system in section four. In section five, we discuss the consequences of the caste system and finally we summarize this chapter in section six.


As an important part of today's social development, cities are also an important guarantee for the improvement of people's living standards. As an important model of urban spatial layout, urban planning and management plays an important role in the development of urban economy, politics and culture. Based on this, this paper takes "urban planning and management" as the research theme, analyzes the existing planning model, and starts from the aspects of content and form, improves the pertinence and directivity of the existing planning system, so as to provide valuable reference for experts in the field.


Feature extraction is quite valuable for the mining and utilization of valid information in hyperspectral remote-sensing imaging and the increase of subsequent classified applications. For improving the dimension reduction effect,a subspace-modulated kernel principal component analysis( SM-KPCA) method is proposed. With this method,the grouping natures of hyperspectral data are integrated into a uniform kernel method framework and a subspace-modulated kernel is constructed. SMK( subspace-modulated kernel) achieves a sparse modulation on the spectral waveband by means of feature grouping; in addition,it is a data-adaptive kernel for measuring the nonlinear similarities among the hyperspectral data specimens. With the proposed method,AVIRIS( airborne visible infrared imaging spectrometer) real hyperspectral imaging is applied for evaluation. Additionally,this method is compared with the conventional kernel method and the spectrally weighted kernel method. The experimental results show that the SM-KPCA method more sufficiently utilizes the complex and relevant physical characteristics between wavebands. Therefore,it outperforms both the conventional kernel methods and the spectrally weighted kernel method regarding the aspect of the classification of hyperspectral images.

Seasonal effects of water column stability, phytoplankton growth, and copepod grazing on the biomass of phytoplankton size fractions are described in the context of variations in particulate organic carbon (POC). Net plankton biomass was more variable in time (between weeks and months), while nanoplankton biomass was more variable in space (between surface and bottom layers and between stations). Biomass was highest and most uniformly distributed during February-IMarch when net plankton diatoms dominated and doubling times approximated the flushing time of the plume. Biomass declined rapidly with depth and distance from the mouth of the estuary during June-July when nanoplankton dominated and doubling times were short relative to the flushing time of the plume. Variations in POC were well correlated with phytoplankton biomass when net plankton dominated and biomass was limited by sinking and mixing. When nanoplankton dominated, biomass was limited mainly by grazing and correlations between POC and biomass were poor. It appears that most of the biomass produced by net plankton diatoms sinks from the surface layer before the summer thermocline develops, while most of the biomass produced by nanoplankton during the summer enters pelagic food chains before sinking from the surface layer,


Based on extensive survey work throughout the country carried out in 2002 and 2003, the paper presents a survey of female labour activity and remuneration in rural Afghanistan. In more than half the groups surveyed, women contribute to income-generating activities. The percentage is larger, but not much larger, among the poor and very poor (60%) than among the medium and better off (46%). Activities demanding better skills, more capital and access to markets (such as embroidery or tailoring) are more frequently practiced by women whose household is in the upper echelons of the village wealth ladder. Few women participate in agricultural activities, and then mainly among the poorer sections of the community. Domestic service is also quite frequent, especially among the very poor (including many widows) whose economic condition forces them not to shun this otherwise low-prestige occupation.

Abstract The young real estate market in Vietnam, an emerging country in Asia, has been growing remarkably. This is an attractive channel for investors, but it seems to be an unstable market and have high potential source of earnings management while investing in real estate companies listed in Vietnamese stock market. The research has been conducted to investigate the impact of the ownership structure on the earnings management of Vietnamese listed real estate companies. The research methodology includes four statistical approaches OLS, FEM, REM and REM (robust) that are employed to address econometric issues and to improve the accuracy of the regression coefficients. The research sample consists of 180 firm-year observations for 36 real estate companies listed on Vietnamese stock market over a period of five years, i.e. from 2014 to 2018. The results show that, while state ownership showed a positive influence, managerial ownership played negative significant roles in relation to earnings management. This research has implications for designing a better ownership structure in the Vietnamese real estate sector and enhancing information quality to protect investors.
