High‐resolution tracking of stem cells remains a challenging task. An ultra‐bright contrast agent with extended intracellular retention is suitable for in vivo high‐resolution tracking of stem cells following the implantation. Here, a plasmonic‐active nanoplatform was developed for tracking mesenchymal stromal cells (MSCs) in mice. The nanoplatform consisted of TAT peptide‐functionalized gold nanostars (TAT‐GNS) that emit ultra‐bright two‐photon photoluminescence capable of tracking MSCs under high‐resolution optical imaging. In vitro experiment showed TAT‐GNS‐labeled MSCs retained a similar differentiability to that of non‐labeled MSCs controls. Due to their star shape, TAT‐GNS exhibited greater intracellular retention than that of commercial Q‐Tracker. In vivo imaging of TAT‐GNS‐labeled MSCs five days following intra‐arterial injections in mice kidneys showed possible MSCs implantation in juxta‐glomerular (JG) regions, but non‐specifically in glomeruli and afferent arterioles as well. With future design to optimize GNS labeling specificity and clearance, plasmonic‐active nanoplatforms may be a useful intracellular tracking tool for stem cell research. An ultra‐bright intracellular contrast agent is developed using TAT peptide‐functionalized gold nanostars (TAT‐GNS). It poses minimal influence on the stem cell differentiability. It exhibits stronger two‐photon photoluminescence and superior labeling efficiency than commercial Q‐Tracker. Following renal implantation, some TAT‐GNS‐labeled MSCs permeate blood vessels and migrate to the juxta‐glomerular region.


A novel smart catalytic system was successfully constructed by using poly[(dimethylamino)ethyl methacrylate] (PDMAEMA) brush grafted graphene oxide (GO) to load gold nanoparticles (Au NPs). The catalytic activity of the Au NPs was finely tuned by temperature, which can control the inclusion and 'exposure' of Au NPs inside the PDMAEMA brushes via the phase transition of the grafted PDMAEMA chain triggered by a temperature above the lower critical solution temperature (LCST) of PDMAEMA.


Objective To explore the influence of pretreatment with simvastatin on the postoperative cognitive function in rats with splenectomy through the Y-type maze tests. Methods 84 SD male rats were randomly divided into four groups: sham group,splenectomy group,simvastatin group and treatment group.Sham group and splenectomy group received saline gastric gavage while simvastatin group and treatment group received simvastatin gastric gavage 10 mg/(kg·d).Splenectomy group and treatment group were performed operations of splenectomy,and at 1,3,7 days after the operation observing the postoperative cognitive function of rats through the Y-type maze tests. Results There was no difference statistically between splenectomy group of preoperation and postoperation and the other three groups(P0.05). Conclusion Operation of splenectomy has no obvious effect on postoperative cognitive function in rats.It is not clear whether pretreatment with simvastatin can prevent POCD.


The article analyses the preservation, development, and further prospects of the functioning of the sacred and architectural objects of the Pereiaslav open-air museum in the conditions of the full-scale Russian-Ukrainian war and the post-war reconstruction of the Ukrainian state. A review of the history of the construction and operation of church buildings was carried out. Their architectural features are characterised. The circumstances of museification are considered. Particular attention is paid to the peculiarities of the coexistence of museum exhibits and religious buildings and the visitors' perceptions of this phenomenon. It is shown that during the totalitarian era, as a result of the state struggle against religion, a huge number of Ukrainian sacred monuments were destroyed, but thanks to the ascetic activities of museum workers, some of them were saved. It was revealed that M. Sikorskyi, M. Zham, together, not only saved sacred objects from complete destruction, but also restored the previous appearance of monuments, thereby preserving them for the contemporaries and descendants. It has been clarified that what the totalitarian Soviet government could not destroy, now it is trying to destroy the criminal Putin regime, therefore, there is an urgent need to carry out a 3-D recording of all historical, cultural, and artistic monuments in Ukraine, if possible, in order to successfully restore them in the event of possible damage to the original appearance of objects. It has been proven that sacred sights are an important component of the development of cognitive types of tourism. The importance and necessity of including the sacred monuments of the museum and the city of Pereiaslav in tourist routes are argued. Their sacral-tourist potential for the development of excursion-religious tourism is determined. The further effective use of sacred monuments for the further development of the tourist resource is substantiated. The results of the research can be used by museum workers, local self-government bodies, and tour operators to develop and substantiate prospective plans for the optimization, improvement, and development of tourist activities based on the sacred heritage of the museum for its popularisation on the domestic and international market for tourist services.


In this paper we studied the influence of pre-treating the surface of 100Cr6 steel by ion beam nitriding at low temperature (380°C) on the surface topography and wear resistance of thin TiN coatings deposited by reactive ion beam assisted deposition. The specimens were characterized by grazing incidence X-ray diffraction, scanning electron microscopy and atomic force microscopy. The wear resistance of the TiN-coated specimens was evaluated by means of ball on disc tests. The results showed that application of a preliminary ion beam nitriding treatment slightly increased the surface roughness but improved the wear resistance of the 100Cr6 steel due to the formation of a diffusion zone containing the γ'-Fe4N nitride combined with the TiN coating.


The Visual Interaction Platform (VIP) is an Augmented Reality system that was designed to make better use of well-developed human skills for real world object manipulation. The platform supports several applications in which physical interaction elements are used to control virtual elements. In this demonstration, we specifically discuss two applications that were created on the VIP. The Electronic Paper (EP) prototype offers natural interactions such as sketching and handwriting and two-handed manipulation, which are especially important for applications such as architectural or industrial design. In order to combine the advantages of the EP prototype with the advantages of existing desktop applications, we have also developed and implemented the concept of Visual Interaction Enriched Windows (VIEWs), and have integrated it within the EP tool.


Progress in bioengineering brought a new approach to DNA sequencing, which aim is to give highly reliable output of low cost and in short time. It is 454 sequencing, based on the pyrosequencing protocol, owned by 454 Life Sciences Corporation. Because of the sequences reliability this method is much better than others for assembly purposes. However, produced sequences are much shorter and there are many more of them, which indicate that the problem is harder. Presented algorithm was created to process data from 454 sequencing method. Usefulness of the algorithm has been proven in tests on raw data generated during sequencing of the whole 1.84 Mbp genome of bacteria Prochlorococcus marinus.


This paper describes an approach to detecting malicious code introduced by insiders, which can compromise the data integrity in a program. The approach identifies security spots in a program, which are either malicious code or benign code. Malicious code is detected by reviewing each security spot to determine whether it is malicious or benign. The integrity breach conditions (IBCs) for object-oriented programs are specified to identify security spots in the programs. The IBCs are specified by means of the concepts of coupling within an object or between objects. A prototype tool is developed to validate the approach with a case study.


The purpose of this study, qualitative in nature, was
to know the biopsychosocial changes evidenced by the
woman who is going through menopause, as well as understanding
the meaning she attributes to her experiences
in this phase of her life cycle. Its subjects were eight menopausal
women who participated in educational groups
in a Family Health Unit of Juiz de Fora. For the data
collection, the technique of a semi-structuralized interview
was used. The results showed that for a woman, the
meaning of menopause consists of that which she feels
and expresses in her psychophysical being, considering the
social environment in which she is a part. She demonstrates
needs for dialogue, understanding, to feel productive and
to practice her profession. The educational group is seen
as a source of information and recognition of the signs
and particular symptoms of menopause, as well as a place
where she feels understood, able to share her experiences
with other women who are experiencing the same things.
This study offered considerations about the importance
of the existential dynamics of the woman, while a
biopsychosocial being, having certain peculiarities during
the period of menopause. It also brought up important
considerations for the health professionals in the groups
regarding their practice and teaching, in what concerns
the care and assistance provided to the woman during this
phase of her life cycle.

Abstract We develop new techniques to classify basic algebras of blocks of finite groups over algebraically closed fields of prime characteristic. We apply these techniques to simplify and extend previous classifications by Linckelmann, Murphy and Sambale. In particular, we fully classify blocks with 16-dimensional basic algebra.


The purpose of this study was to determine the degree to which teacher‐subjects' ratings of videotape samples of children's speech would correspond to ratings of the speech that teachers might presume to hear from children of certain ethnic and social status groups. Using a previously developed semantic differential instrument, ratings of stereotype descriptions of children as well as videotape samples of children presumed to be representative of the stereotype descriptions were obtained from fifteen subjects. Results indicated a correspondence between teacher's ratings of stereotyped descriptions and videotape speech samples of children.


Sir: Catechins in fresh tea leaves are oxidized to form colored substances during the fermentation process of manufacturing black tea. In order to identify the oxidation products which account for the red color characteristic of black tea, enzymic oxidations of individual catechin, alone or in suitable combination of them, were carried out. When epigallocatechins, (Gc) was incubated with tea oxidase together with epicatechin (Ec) , it was found that a remarkable red color develops, and the paper chromatogram showed an orange spot of RF-values: 0.08 (2% AcOH) and 0.37 (BuOH—AcOH—H2O, 4:1:5). On the other hand the substance corresponding with the orange spot was also found to be formed by the oxidation of a mixture of Gc and Ec with potassium ferricyanide and sodium hydrogen carbonate. Therefore the further chemical study has been continued on the colored substance obtainable by this

It is an indicator of the effectiveness of the optimization of technical solutions of embodiment washing-squeezing machines and the basis for the fundamental analysis of typical designs.


Since the 19th century the theory of evolution has been the guide not only of biological research, but of the explanation of man's psychic and mental abilities, too. In particular Herbert Spencer's and Charles Darwin's works gave rise to an evolutionary view of human mind (evolutionary psychology). This view was generalized to the explanation of epistemic structures like science and was adopted by many philosophers and scientists, e. g. Boltzmann, Mach, and others. Under the influence of Darwin's theory of natural selection a selective elimination model was established in order to explain epistemic activities. Thus, in the 19th century we find expressed the basic ideas of today's evolutionary epistemology. The modern evolutionary theory of (human) knowledge therefore turns out to be the more precise and elaborated formulation of the fundamental postulates of an evolutionary psychology.


There is a need for a general policy management architecture that can guide one in understanding and implementing policy in diverse management applications. The question of policy in network management has evolved since the early '70s concern with monitoring and controlling the access rights of multiple users and resources in large distributed systems. It is now generally acknowledged that policy also plays an important role in other areas of network management, including configuration, accounting, fault, and performance management. Furthermore, it is agreed that a general policy framework is needed for controlling the behavior of the agents the enterprise network comprises, including network users, administrators, troubleshooters, the applications running on the network, and the operational parameters of network hardware. The authors present a framework for understanding and implementing policy in the management of enterprise networks. We describe typical network scenarios in which policy plays a role, a general architecture for policy management and the components and operations of the architecture at a level of abstraction that renders it applicable to specific management tasks which require policy. We also provide an example of the architecture in configuration management. The article draws from work on policy management, including two ESPRIT projects.


Abstract The paper focuses on integration of monitoring and control of the main parts of ship propulsion plant - it means : main engine - shaft generator - pitch propeller. Each of these parts has its own controllers, but there is a lack of one supervisory, one level higher, device gathering and monitoring the whole system. This gap is fulfilled by the one supervisory controller based on neural network principles. (Iracki K., 2005); (Kruszewski J., 2002); (Kruszewski J. 1999);(Żurada J., Barski M., Jedruch W. 1996) The paper consist of three parts, the first one describes the problems and purposes of the controller usage, the second one presents the dynamic model of the ship basic parts and propulsion system and the third part presents the whole dynamic system with supervisory neural controller. Matlab/Simulink enclosing neural network data base was used as a main tool to realize computer simulation of the system.


The invention discloses a silicon material heat source structure and a manufacturing method thereof. The manufacturing method comprises the steps of firstly, fabricating a heating element by use of photoetching and lift-off processes, secondly, forming a cantilever beam structure heating element by etching a corresponding cantilever beam structure, and finally, forming a supporting cavity on which a high-thermal resistance reflecting film is attached on a silicon structure. The silicon material heat source structure is formed by bonding the cantilever beam structure heating element to the surface-treated supporting cavity on which the high-thermal resistance reflecting film is attached, and is of a micron dimension; according to the manufacturing method, a thermal island is formed by use of a suspension method, and meanwhile, a surrounding thermal reflecting cavity on which the high-thermal resistance reflecting film is attached is formed under the thermal island to guarantee the directionality of heat radiation, and consequently, a unidirectional radiation heat source can be manufactured and is high in heat conduction efficiency; the manufacturing method is applicable to the micro-electro-mechanical field and also to traditional heater manufacturing to realize higher accuracy.


To meet the demands of a rapid algorithm for the envelope alignment in engineering application,this paper proposes a valid and fast algorithm.The algorithm selects a peak envelope with the maximum correlation as a reference signal to calculate the offset.In the selection process of the maximum correlation peak envelope,the non-coherent accumulated wave is passed by a low-pass filter to filter the high frequency components,so that the detection of peaks becomes easy and rapid.Finally,the algorithm is tested and evaluated by real data.The result shows that the algorithm can reduce the calculation to meet engineering applications,and has a better alignment effect compared with the traditional method.


The structural characteristics of a pentane-insoluble asphaltene isolated from the vacuum residue of an Arabian crude mixture have been investigated by pyrolysis gas chromatography/ mass spectrometry (py/GC/MS), 1 H/ 13 C NMR, gel permeation chromatography (GPC), and matrix-assisted laser desorption/ionization time-of-flight (MALDI TOF) mass spectrometry. Assignments of NMR signals of the asphaltene have been discussed briefly on the basis of the information from the literature and compared with those of an aliphatic fraction isolated from the ruthenium ion catalyzed oxidation products of the asphaltene. The comparison data indicated that aliphatic substitution >C 1 on aromatics are little; however, most of the chain methylene groups are located within a polymeric-saturated fraction of the asphaltene. The average size of aromatic fused ring systems has been determined to be 4-5 for the sample. Pyrolysis tests implied that the asphaltene sample is constructed with relatively large polycyclic units connected by relatively strong bonds. Our results also support a view that asphaltene is the mixture of complex polydispersed molecules with large variation of molecular sizes.


Ten Mexican strains of Pleurotus ostreatus, isolated from specimens growing on different substrates in Xalapa region, Veracruz, were cultivated on coffee pulp and barley straw. Strains showed variation in fresh fruiting body production and biological efficiency on each substrate. Highest biological efficiencies were obtained for strain INIREB-21 (138.13 %) on coffee pulp, and for strain INIREB-26 (96.04 %) on barley straw. Time to produce the first fruiting body primordia and that for fruiting body development were mostly earlier on barley s traw than on coffee pulp.


Study of isolated anaphylactic lungs by perfusion methods 1 shows that there are three types of pulmonary anaphylactic reaction: (a) Bronchial Anaphylaxis, or the spasmodic contraction of the bronchial musculature, unassociated with recognizable changes in the pulmonary blood vessels. This type of reaction is illustrated by the lungs of actively sensitized and actively immunized guinea pigs, and by the lungs of guinea pigs passively sensitized with homologous serum. (b) Vascular Anaphyalxis, or the spasmodic contraction of the pulmonary blood vessels, usually accompanied with edema. The vascular reation is usually followed by a mild bronchial reaction. This type of reaction is illustrated by the lungs of guinea pigs passively sensitized with heterologous serum, and by the reaction of normal lungs to certain protein split-products and incubated blood mixtures. (c) Pseudo-Anaphylaxis, or the plugging of the pulmonary blood vessels with thrombi and agglutinated corpuscle masses.


Abstract : An improved salting-out extraction-preconcentration, RP-HPLC-UV protocol for the determination of nitroaromatics and nitramines in water was developed. The method involves saturating a 760-mL water sample with NaCl and extracting with acetonitrile (ACN). Collected extracts are then preconcentrated and solvent exchanged to water via a Kuderna-Danish evaporator. Analysis involves solute focusing by introducing an 1100-mL sample onto a LC-8 column eluted with water, MeOH and THF (70.7:27.8:1.5V/V/V) at 2.0 mL/min followed by UV detection at 254 nm. A direct injection RP-HPLC-UV water method was developed concurrently, employing the same separation and detection techniques. Both methods are applicable for simultaneous determination of RDX, TNB, DNB, TNT, 2, 4-DNT, 2,6-DNT, 2-Am-DNT and 4-Am-DNT, and HMX (salting out only) with reporting limits ranging from 0.006 to 0.27 micrograms/L for the salting-out method and 0. 12 to 1.07 micrograms/L for the direct injection method. The salting-out extraction procedure is suitable for determination of HMX, RDX, TNT, 2,4-DNT and 2,6-DNT at concentrations below the health advisory and water quality criteria proposed by the USEPA and Oak Ridge National Laboratory.

Multilingual representations pre-trained with monolingual data exhibit considerably unequal task performances across languages. Previous studies address this challenge with resource-intensive contextualized alignment, which assumes the availability of large parallel data, thereby leaving under-represented language communities behind. In this work, we attribute the data hungriness of previous alignment techniques to two limitations: (i) the inability to sufficiently leverage data and (ii) these techniques are not trained properly. To address these issues, we introduce supervised and unsupervised density-based approaches named Real-NVP and GAN-Real-NVP, driven by Normalizing Flow, to perform alignment, both dissecting the alignment of multilingual subspaces into density matching and density modeling. We complement these approaches with our validation criteria in order to guide the training process. Our experiments encompass 16 alignments, including our approaches, evaluated across 6 language pairs, synthetic data and 5 NLP tasks. We demonstrate the effectiveness of our approaches in the scenarios of limited and no parallel data. First, our supervised approach trained on 20k parallel data (sentences) mostly surpasses Joint-Align and InfoXLM trained on over 100k parallel sentences. Second, parallel data can be removed without sacrificing performance when integrating our unsupervised approach in our bootstrapping procedure, which is theoretically motivated to enforce equality of multilingual subspaces. Moreover, we demonstrate the advantages of validation criteria over validation data for guiding supervised training.

Horace Miner, in his satirical account of the meticulous and often pednfiil customs Americans practice in caring for their bodies, failed to mention one of the most common masochistic rituals—the removEil of hair from the legs and armpits of the female hody.' Women have for countless years heen concerned with the occurrence of hair on their hodies. They have removed the hair from their head, from the puhic areas, and from their faces and have used it for erotic purposes. Butin puhlic advertising, the most ohvious areas of concern have heen the legs and armpits. Female observers have heen quick to comment on the misery that the customs of removing hair from these parts of the hody have occasioned. Rohin Morgan calls "heing agonized at fourteen because you have finally shaved your legs, and your flesh is on fire" one of the "harharous rituals" of heing female in America."^ Emily Prager, a young adult recounting the preparations she goes through before a date, acknowledges that the harharity ofthe ritual does not disappear with early adolescence, "I used to shave my legs just hefore the date. I wanted to he sure they were ultra-smooth for the evening ahead. It took years of frantic last-minute efforts to (1) weish out the hlood spots on my panty hose while (2) trying not to reopen the shaving nicks while (3) somehow detaching the sticky nylon from the severed skin, hefore I realized that one hour hefore a date is no time for me to have a razor in my hand."^


This document describes smells and refactorings found in literature used for quality assurance of UML models. We focus on model smells and model refactorings applicable in early stage of model-based software development, i.e. during requirements analysis and early design phases. Therefore, the presented catalog should be seen as representative. With another focus, the selection of model smells and refactorings would be different. Furthermore, all model smells and refactorings described are related to at least one model quality aspect each affected by this technique. Please note that these assignements are under discussion. Model quality aspects are discussed based on two articles presented by Mohagheghi et al. [15] and Fieber et al. [7]. The main results of these articles are presented in the first chapter whereas Chapters 2 and 3 present 17 UML model smells and 27 UML model refactorings altogether in a structured way.


This is a light-hearted friendly introduction to the theory of Legendrian knots intended for non-experts in the field. This includes ice-skating and an application to complex geometry. In this note I would like to give a view on contact and symplectic topology. This area of mathematics lies at the intersection of several different branches: complex algebraic geometry [7, 8], geometric topology [10, 12] and differential equations [1, 11] amongst them. To exemplify this I will focus on one of these relations, between the complex solutions of a polynomial equation and Legendrian knots, explored in the article [2]. We will work with the following example: X = {(x, y, z) : xyz + x+ z = 1} ⊆ C, i.e. we define X to be the space of triples of complex numbers (x, y, z) which verify the polynomial equation P (x, y, z) = 1, where P (x, y, z) = xyz + x + z. I would like to explain to you why the symplectic geometry of this space is completely contained in the Figure 1. Figure 1. The contact topologist take on X = {(x, y, z) : xyz + x+ z = 1} ⊆ C. But first, there are two main questions I would like to address: A. Why would we ever care about the symplectic geometry of X ? B. What does the colourful Figure 1 represent, and why is it useful ? In short, the former question can be answered by saying that symplectic topology is the aspect of the geometry of X that is robust with respect to small polynomial perturbations. In addition, lots of the geometric properties of X are already captured by symplectic invariants [11, 13]. The answer to the latter question is even more exciting: Figure 1 represents a Legendrian knot, that is, a knot in 3–space which is constrained to be tangent to certain 2–planes. Having such Figure 1 is genuinely useful because just by pictorial manipulation we can solve many questions about the geometry of the space X. That is, we can translate questions about X to combinatorial questions about a drawing such as Figure 1, establish a set of combinatorial rules and play the game. The following two sections treat each of these questions in more detail and will hopefully convey both the flavour and a small part of the many benefits of the study of Legendrian knots. 1. Polynomial Equations From graph theory to differential equations, the ubiquity of polynomials is manifest in mathematics. For instance, let us suppose that we need to understand the solutions of the Painlevé I equation g′′(t) = 6g(t) + t,


An ongoing problem in remote sensing is that imagery generally consumes considerable amounts of memory and transmittance bandwidth, thus limiting the amount of data acquired. The use of high quality image compression algorithms, such as the wavelet-based JPEG2000, has been proposed to reduce much of the memory and bandwidth overhead; however, these compression algorithms are often lossy and the remote sensing community has been wary to implement such algorithms for fear of degradation of the data. We explore this issue for the JPEG2000 compression algorithm applied to Landsat-7 Enhanced Thematic Mapper (ETM+) imagery. The work examines the effect that lossy compression can have on the retrieval of the normalized difference vegetation index (NDVI). We have computed the NDVI from JPEG2000 compressed red and NIR Landsat-7 ETM+ images and compared with the uncompressed values at each pixel. In addition, we examine the effects of compression on the NDVI product itself. We show that both the spatial distribution of NDVI and the overall NDVI pixel statistics in the image change very little after the images have been compressed then reconstructed over a wide range of bitrates.


Effective control of the logistics costs of the power grid engineering cost project can minimize the total cost, and improve the economic efficiency of it. This paper regards the minimal logistics cost of the power grid engineering cost project in the total life cycle as goal, and puts forward the project logistics time-cost trade-off optimization model based on improved ant colony algorithm. This model integrates the two objectives of time and cost into a single objective in terms of adaptive weight approach, and this approach is applied to ant colony algorithm to search for solutions. The result of the case study indicates that this approach is very effective for determining practical solutions, and has strong global searching ability and efficiency. So the model is very suitable for solving the problem of power grid engineering cost project logistics cost optimization.


Abstract. Three new species from Ecuador are described: America spinosa and America tuberevexa, from Napo Province, and Elytrimitatrix (G.) franki, from Loja Province. America biplagiata (Villiers, 1958), a species known only from the holotype, is redescribed based on males and females. The unknown male of Paracometes solangeae Botero & Almeida, 2019 is described and illustrated by the first time. Distenia (D.) normae Botero & Almeida, 2019 is proposed as a junior synonym of America wappesi Santos-Silva & Tavakilian, 2009. Moreover, the known geographical distributions of 10 species of Disteniidae are expanded.


SUMMARY 3-D gravity models that consider the highly complex density structure of the Norwegian passive volcanic continental margin require a significantly lower density in the mantle below the ocean than below the continent. This is especially pronounced on the crust-free residual gravity anomalies obtained by 3-D gravity stripping. This density contrast in the mantle indicates different physical properties either related to thermal or compositional conditions beneath the two domains. We assess the gravity response of thermal differences and find that a hotter oceanic mantle compared to a colder continental mantle could cause the density contrast. Accordingly, 3-D lithospheric-scale gravity models considering temperature-dependent mantle densities indicate that the transition between continental and oceanic lithosphere is rather sharp with a steep gradient in thickness beneath the continent–ocean transition zone. Furthermore, a mantle wedge of reduced density extends from the oceanic Jan Mayen Fracture Zone to the continental Jan Mayen Lineament and points to increased mantle temperatures and/or compositional changes beneath the lineament. The models further indicate the presence of high-density bodies within the lower crust at the continent–ocean transition that are continuous with the lowermost oceanic layer 3B in terms of geometry and density. This supports the concept of underplated lower crust beneath the western Norwegian margin. Finally, NE–SW trending linear zones of increased density are required in the lower crust beneath the eastern Voring and More Basins to fit the short-wavelength gravity signal.


The research has aimed to determine the influence of work discipline to the employee performance at PT Hindoli Cargill Kabupaten Musi Banyuasin South Sumatera, the method used by the author are a quantitative method.Data collection techniques that writer do are observation, interview, and questionnaires.Based on the results of the research show the application of the rules on disciplinary violations committed have an impact on employee performance because does not know the indicators that will be assessed by the company, and timing of, in this case the need for firmness of a leader of the company to students.Problems: Lack of awareness of employees to comply with regulations concerning labor discipline set by the company such as (1) There are still staff employees who come late to office, (2) Permission to go home without explanation. Consequently the work that has been assigned to employees delayed or not completed or not realized within the time specified by the company.Suggestions: (1) So that a work is not delayed and can be realized, then the employee can start from within yourself first, after which it can be applied in other occupations. (2) Leader must be more assertive in taking action and give punishment to the indiscipline employee.


A.-The active immunization of infants and children against a number of infections is at present in a confused state well illustrated by the correspondence columns in recent issues of the Journal.`5 For years it has been the established practice to use (a) prophylactics containing alum because of their high immunizing value, (b) combined prophylactics in order to save the infant from an unnecessary number of pricks. The investigations of the Medical Research Council on post-inoculation poliomyelitis,' however, have shown that there is a definite risk of paralytic poliomyelitis within 28 days of the injections when this disease is prevalent and that the risk varies with the nature of the prophylactic acid. After alum-containing prophylactics like A.P.T., P.T.A.P., and alum-adsorbed pertussis vaccine, and also after alum-free but combined diphtheria-pertussis prophylactic, the risk lies between 2.1 and 6.7 per 100,000 inoculations, whereas during the same period the calculated incidence of poliomyelitis in the absence of inoculations works out at 1.3 per 100,000. (These estimates were based on a small number of cases.) After diphtheria formoltoxoid (F.T.), after T.A.F., after a plain suspension of pertussis vaccine, and after smallpox vaccination the risk is not greater than in the general population; there is also no greater risk with intramuscular than with subcutaneous injection: In the present state of opinion on all active immunizations, no recommendation can be dogmatic or final. If one accepts the findings of the M.R.C. committee, then, when poliomyelitis is prevalent, all alum-containing prophylactics should be discontinued, except perhaps for subjects already immunized against poliomyelitis. In the case of the alum-adsorbed pertussis vaccine this would be no disadvantage. In the case of A.P.T. and P.T.A.P. it would mean the loss of valuable prophylactics-indeed, an instance of " scorning the base degrees by which we did ascend." The choice lies between F.T. and T.A.F. T.A.F. has many drawbacks: (1) at least 3 injections are necessary to immunize, (2) it is contraindicated in subjects suffering from asthma or eczema, (3) it is apt to sensitize against future injections of serum that may have to be given therapeutically; it has a place, however, in the immunization of some adults and older children. For infants and young children F.T. should be used. Also, when poliomyelitis is present, a scheme of immunization will have to be formulated in which only single antigens are used. Leaving out for the present the question of tuberculosis prevention, the optimum ages and the optimum order of the various immunizations mentioned by the questioner would be as follows: Pertussis: 1st, 2nd, 3rd month (3 injections of the plain suspension of pertussis vaccine). Smallpox: vaccination during the 4th month. Poliomyelitis: 5th and 6th month (2 injections of the poliomyelitis vaccine at intervals of 3-4 weeks and possibly a third at some later date). Diphltheria: 7th and 8th month (2 injections of F.T. at 4 weeks' interval). Tetanus: between the 11th and 18th month (3 injections of tetanus toxoid at intervals of 6 weeks and 6 months). This makes a total of 11 to 12 inoculations in 18 months -to say nothing of booster doses against diphtheria and tetanus when the child is about 5 years old-a really intolerable number of inoculations which very few parents would accept. A compromise could be made by immunizing the child at the 7th month against both diphtheria and tetanus by giving 2 injections of combined F.T. and tetanus toxoid at an interval of 6 weeks, and 6 months later-i.e., about the 14th month-an injection of combined F.T., tetanus toxoid, and plain pertussis vaccine. The risk of poliomyelitis would probably be negligible, as the child would have been already immunized against the disease. (In the present state of our knowledge it is probably wiser not to combine poliomyelitis vaccine with other prophylactics.) When poliomyelitis is not prevalent a simpler scheme of immunization could be adopted, using combined antigens but no alum-containing prophylactics (see Table). For the prevention of tuberculosis, the present procedure is to inoculate with B.C.G. (1) all newborn infants who are likely to be exposed to a family infection and to separate them from the infection for at least two months, when the tuberculin test should be positive, (2) all children 14 years old who are tuberculin-negative before they leave school, and (3) all medical students and nurses who are tuberculinnegative when they join a hospital. According to an investigation by a committee of the Medical Research Council,5 as


Summary Litter and logging residue retained in situ as a mulch has several beneficial aspects that can assist in maintaining the productivity of radiata pine (Pinus radiata D. Don) plantations on sandy soils in the Mt Gambier region of southern Australia. These benefits include the conservation of soil moisture, conservation of nutrients, protection of soil, and provision of a more favourable environment for root development in the surface soil horizons. The maintenance of site fertility by the addition of fertilisers is discussed and compared in both 'burn' and 'non-burn' situations. Mulching the litter and logging residue is operationally feasible and is an option that should be considered by plantation managers when re-establishing radiata pine, particularly on soils of low to moderate fertility.


Extracting Protein-Protein Interactions (PPIs) from text is a relevant problem in the biomedical field and a challenge in the area of machine learning. In the biomedical field, the PPIs are fundamental to understand the functioning of living organisms. However, the number of articles related to PPIs is increasing rapidly, hence it is impractical to identify and catalog them manually. For example, in the case of human PPIs only 10 % have been cataloged. On the other hand, machine learning methods based on kernels are often employed to automatically extract PPIs, achieving state of the art results. These methods use lexical, syntactic and semantic information as features. However, the results are still poor, reaching a relatively low rate of F-measure due to the complexity of the problem. Despite efforts to produce sophisticate kernels, using syntactic trees as constituent or dependency trees, little is known about the performance of other Machine Learning approaches, eg, Bayesian networks. Constituent tree structures are graphs which contain important information of the underlying grammar in sentences containing PPIs. On the other hand, the Bayesian network allows modeling some rules of grammar and assign to them a probability distribution according to the training sentences. In this master thesis we propose a method for automatic construction of Bayesian networks from constituent trees for extracting PPIs. The method was tested in five corpora, considered benchmark of extraction of PPI, achieving competitive results, and in some cases better results when compared to state of the art methods.


A clinical trial conducted by the Chennai Tuberculosis Research Center and its unit at Madurai South India assessed 3 short-course oral antituberculosis regimens under field conditions. 1203 patients with sputum-positive pulmonary tuberculosis were randomly assigned to receive either 1) an 8-month daily regimen of ethambutol isoniazid rifampicin and pyrazinamide for 2 months followed by ethambutol and isoniazid for 6 months; 2) a 6-month twice-weekly regimen with the same 4 drugs for 2 months followed by ethambutol isoniazid and rifampicin for 4 months; or 3) regimen 2 but without ethambutol. In regimen 1 drugs were given completely unsupervised; in regimens 2 and 3 supervision was partial or complete. At the end of treatment 3.6% of 305 patients in regimen 1 0.4% of 263 patients in regimen 2 and 9.3% of the 257 in regimen 3 had an unfavorable bacteriologic response. At 24 months after the initiation of treatment 5% 11% and 10% of patients in the 3 groups respectively had a bacteriologic relapse requiring treatment. Among patients with bacilli initially resistant to isoniazid the unfavorable response and relapse rates respectively were 17% and 8% in regimen 1 (n = 94) 20% and 25% in regimen 2 (n = 59) and 62% and 15% in regimen 3 (n = 74). These findings suggest that a fully unsupervised ethambutol-containing regimen given daily for 8 months is highly effective even in the presence of isoniazid-resistant bacilli. Although directly observed treatment remains the ideal it appears that reductions in the number of required clinic attendances can improve patient adherence to tuberculosis treatment without compromising efficacy.

Airborne multichannel high-resolution radar (HRR)-ground moving target indication (GMTI) is of great significance to wide-area surveillance, traffic monitoring, and target recognition. The Aerospace Information Research Institute, Chinese Academy of Sciences, produced an advanced airborne digital array radar with high resolution and conducted an experiment with slow and weak cooperative moving targets in 2021. In this article, an overall processing framework for target detection, parameter estimation, and target tracking using this system is introduced. For HRR detection, the echo energy of targets is spread into multiple range units, so-called range-spread targets; thus, using detectors designed for pointlike targets will severely degrade the detection performance, especially for slow and weak targets. To address the adaptive detection of such range-spread targets embedded in Gaussian clutter with an unknown covariance matrix, a novel two-step generalized space–time adaptive processing (GSTAP) algorithm is proposed, which offers an enhanced clutter suppression capability compared with natural competitors. Moreover, a tracking method is implemented in the range-Doppler domain to avoid track loss caused by azimuth relocation error and reject discrete false alarms. Both simulation and experimental results are presented to demonstrate the effectiveness of the proposed method and provide a paradigm for further research.


In 1984 and 1985, a fungus was observed parasitizing larvae of Aedes kochi collected from leaf axils of Colocasia sp. in a rainforest in Queensland, Australia. In axenic culture, the fungus produces singlecelled, cylindrical and cuneiform conidia which are borne in slime from subulate phialides. Based on its development of conidia of two types, its parasitism of mosquito larvae, and its underwater conidiation, the fungus is described as the new species, Culicinomyces bisporalis. The fungus is compared with similar fungi belonging to several genera. Tolypocladium parasiticum Barron, the only species of Tolypocladium known to produce conidia underwater, is also shown to produce conidia of two types, and is redisposed as Culicinomyces parasiticus Sigler, comb. nov. Tolypocladium is maintained as a genus distinct from Beauveria.


Social media has been lauded as a democracy catalyzer while overlooking the adversarial opportunities it offers: Social media isn't going to overthrow authoritarianism but it might help to pave the way for authoritarian manners in democratic countries.


The mating behaviour of the corn stalk borer Sesamia nonagrioides (Lef.) [Lepidoptera: Noctuidae] was studied under laboratory conditions at 25 ± 1 ° C, 65 ± 5 % r.h. and 16:8 (L:D) regime. The females began calling during the first scotophase following emergence, the peak of calling occurred during the second scotophase and thereafter decreased. Maximum calling was observed between the fourth and sixth hour of the scotophase. The calling pattern varied with age. During the first and second scotophase most of the females were calling continuously, while during the third and fourth scotophase periodic calling was observed. The mean onset of calling was advanced and the mean length of calling per day was increased slightly as the female became older. Females held for 72 h in continuous darkness exhibited an endogenous circadian rhythm of calling. Matings began during the first scotophase following emergence and the peak of mating was observed during the second scotophase. Mated females did not remate. Few males mated more than once during the following scotophases.

A sensitive laser spectroscopic method has been applied to the quantitative determination of the isotope ratio of helium at the level of 3He/4He = 10−7 − 10−5. The resonant absorption of 1083 nm laser light by the metastable 3He atoms in a discharge cell was measured with the frequency modulation saturation spectroscopy technique while the abundance of 4He was measured by a direct absorption technique. The results on three different samples extracted from the atmosphere and commercial helium gas were in good agreement with values obtained with mass spectrometry. The achieved 3σ detection limit of 3He in helium is 4 × 10−9. This demonstration required a 200 μL STP sample of He. The sensitivity can be further improved, and the required sample size reduced, by several orders of magnitude with the addition of cavity enhanced spectroscopy.


The properties of the electron-affinic 2-nitroimidazole Ro-07-0582 have been examined in vitro in two Chinese hamster cell lines, CHO and CH2B/sub 2/. The drug was found to sensitize hypoxic cells to radiation damage selectively with a high efficiency. At concentrations greater than 10 mM the drug has a dose-modifying factor of approximately 3.0 in hypoxic cultures. It does not alter the response of aerobic cells. Pre- or postirradiation treatment of cells with Ro-07-0582 has little, if any, effect. At high cell concentrations, where many sensitizers are ineffective, this compound retains most of its radiosensitizing capability. Ro-07-0582 is also shown to have a chemotherapeutic potential in that it demonstrates a very selective toxicity for hypoxic cells after a few hours of exposure. It is much less toxic to aerobic cells. This property, while it may serve as a useful complement to the radiosensitizing effect of the drug, suggests that care must be exercized in the clinical application of Ro-07-0582 to avoid possible injury to normal hypoxic tissues in the body.

The energy dependence of cross sections for inelastic pion scattering to the /Delta/ = /Delta/ = /Delta/ = 1 transition at 15.11 MeV in /sup 12/C is found to map very closely the /Delta/ = /Delta/ = /Delta/+1 /pi/-nucleon scattering cross sections at beam energies from 50 to 295 MeV. This free /pi/-nucleon energy dependence is due to the prominent /Delta/sub 3/2,3/2/ resonance, corresponding to the first excited nucleon state, which is mirrored in the /pi/-nucleus system with little alteration.


An experimental evaluation of an echo-path modeling device is reported for chaotically-coded speech telephony circuits. The device provides an accurate characterization of the far-end echo path using only half-duplex near-end speech during conversational calls. The in-service nonintrusive systems of interest are usually based on a class of least-mean-square (LMS) digital adaptive filters (DAFs). The chaotic-based modulation regime exploits a logistic mapping to optimize the convergence rate of the model while preserving the signal bandwidth requirements. Experimental results show that uncoded speech is ineffective in driving the modeling device when noise-to-echo ratios exceed approximately -30 dB and thus invalidates live measurements. The chaotic modulation, however, increased the echo-to-noise ratio and allowed adaptation for far-end noise conditions exceeding 30 dBs higher than that of the uncoded case.


Nickel hydroxide Ni(OH)2 is widely used as a positive electrode active material in alkaline rechargeable Nibased batteries. It possesses two phases in its reduced states known as α-Ni(OH)2 and β-Ni(OH)2, which transform to γ-NiOOH and β-NiOOH, respectively, during potential cycling. Each polymorph has its own advantages and limitations as described in the table 1. In order to increase of charge/discharge capacity, the utilization of α-Ni(OH)2 has been attempted by several research groups. However, due to the stability criticism, a rapid decrease of capacity during cycle test of Ni-MH batteries using α-Ni(OH)2 caused by phase transition from α-phase to β-phase. We have prepared α-Ni(OH)2 thin films using LPD method previously [1]. In this study, we report on the preparation of a-nickel hydroxide/carbon composite using a very simple and convenient method by LPD process. The main reactions in LPD process can be expressed as follows:


The impact of vitamin B‐6 deficiency on temporal changes in markers of SAA metabolism was determined in weanling pigs. Pigs (5.3 kg; n=6 per group) were fed a semi‐purified diet (20.5% casein; 3474 kcal ME/kg) containing either 0 or 3 mg pyridoxine HCl/kg diet, using a pair‐feeding design. Feed intake was measured continuously, and growth data and blood samples were collected weekly for 6 weeks. Animals were killed at the end of 6 weeks, and tissue samples harvested. Plasma pyridoxal‐5‐phosphate (PLP) was quantified by radioenzymatic assay. Total homocysteine (Hcy) and cysteine (Cys) were measured by reverse‐phase HPLC. From the 4th week until the end of trial, vitamin B‐6 deficiency decreased average daily gain and feed efficiency (p<0.05), despite the pair‐feeding. In B‐6 deficient pigs, plasma PLP decreased substantially after the first week (37 vs.14 nM). At 6 weeks, plasma PLP was significantly higher in control vs. B‐6 deficient pigs (36 vs 5 nM; p<0.0001). Significant decreases in plasma Cys and increases in plasma Hcy, due to B‐6 deficiency, were detected from the 3rd week (p<0.0001). From the 3rd to 6th week, plasma Hcy in controls was 17.70, 13.51, 11.48, and 13.28 μ M, respectively. Plasma Hcy in deficient pigs, however, was 332.48, 403.19, 337.94, and 479.91 μM, respectively. Similarly, vitamin B‐6 deficiency decreased hepatic Cys (164.03 vs. 86.31 nmol/g liver, p=0.04) but increased hepatic Hcy (16.06 vs. 307.41 nmol/g liver, p=0.001).

Security on college campuses is a good thing, especially when it comes to your dorm room or apartment building. But due to high initial cost, the Housing and Business Department at Cal Poly, San Luis Obispo, has opted for a proprietary door lock system which requires encoding new keycards manually for every resident, every year. The goal of this project is to offset this labor cost and drain on resources by automating the keycard encoding process. This project will address the design specifications and economic advantages of automation while also exploring and comparing alternative solutions.

The initial pH, initial concentration of Fe2+ and NaClO on the degradation of ammonium butyl-dithiophosphate using Fe2+/NaClO process have been investigated in this paper. The results shows that under the optimum reaction conditions of a temperature 28°C, pH 4.0, the initial concentration of Fe2+ and NaClO is 15 mg/L and 5.33 mL/L, respectively, about 87.86% ammonium butyl-dithiophosphate removal can be achieved within 150 min by using a Fe2+/NaClO process. The degradation of ammonium butyl-dithiophosphate under different NaClO concentration conditions follows the first order exponential decay equations. The Fe2+/NaClO can efficiently oxidation of ammonium butyl-dithiophosphate in aqueous solution and can be an effective process for the treatment of ammonium butyl-dithiophosphate wastewater.

In this paper, according to the Mannich-Reaction, a kind of chelating flocculant grafted with triethylenetetramine was preparated from polyacrylamide (PAM), formaldehyde and triethylenetetramine. Using this flocculant to remove cadmium from waste water including Cd2+ was studied. Due to the chelate functional group grafted on long chain of the PAM, the flocculant is able to capture Cd2+ through the flocculating effect and the chelate effect. Obviously, the product can be used to flocculate, subside, and remove cadmium from waste water with low concentration of cadmium. The optimal conditions for synthesizing this flocculant and its usage of removal cadmium were experimented. The results show that the synthetic process of the flocculant is easy to operate, and its capability of removing cadmium is obvious and rapid. For the waste water of 10mg/L cadmium concentration, the above 96% of cadmium was removed from water by adding the flocculant with the ratio of 1:57(V/V). Thus, a novel and low-cost method to remove the deleterious cadmium from waste water is obtained.


Stability has been a recurrent issue in training generative adversarial networks (GANs). One common way to tackle this issue has been to propose new formulations of the GAN objective. Yet, surprisingly few studies have looked at optimization methods specifically designed for this adversarial training. In this work, we review the "variational inequality" framework which contains most formulations of the GAN objective introduced so far. Taping into the mathematical programming literature, we counter some common misconceptions about the difficulties of saddle point optimization and propose to extend standard methods designed for variational inequalities to GANs training, such as a stochastic version of the extragradient method, and empirically investigate their behavior on GANs.


A 28 year old man presented to the accident and emergency department with central abdominal pain that had lasted just over a day and was "cramping" in nature. He had had bloody diarrhoea for three days, with increasing frequency and amount of blood. He had eaten a chicken sandwich purchased from a canteen the day before the onset of symptoms. There was no history of recent foreign travel or any important medical history.

On examination he was found to be warm and well perfused, and his abdomen was soft, with mild generalised tenderness. On admission his full blood count, renal function and liver function tests were all within normal range.

Three days after admission he had persistent bloody diarrhoea; his haemoglobin concentration had dropped by 40 g/l to 126 g/l. Colonoscopy and biopsies showed acute indeterminate colitis. His white cell count was 23.3×109/l, neutrophils 19.1×106/l, platelets 49×109/l, international normalised ratio 1.0, APTT (activated partial thromboplastin time)1.0, C reactive protein 256 mg/l, urea 19.7 mmol/l, creatinine 530 µmol/l, potassium 4.8 mmol/l, serum lactate dehydrogenase 3452 U/l. He quickly became anuric.

The CAP operating system [Wilkes79b] has recently undergone a major redesign in order to make its only peripheral the Cambridge Data Ring [Wilkes79a]. The revised system uses the shared servers attached to the network instead of having a set of its own private peripherals. This paper describes how the Cambridge File Server, described in a companion article [Dion80], is used by the CAP computer as a remote backing store. Both file loading and swapping now take place over the network. Appropriate use of the abstractions and facilities provided by the file server has allowed a large amount of the filing system apparatus, including both programs and data structures, to be removed from the CAP operating system.


Cardiovascular diseases (CVDs) are the number one cause of death worldwide. While there is growing evidence that the atrial fibrillation (AF) has strong associations with various CVDs, this heart arrhythmia is usually diagnosed using the electrocardiography (ECG) which is a risk-free, non-intrusive, and cost-efficient tool. Continuously and remotely monitoring the subjects' ECG information unlocks the potentials of prompt pre-diagnosis and timely pre-treatment of AF before the development of any inalterable life-threatening conditions/diseases. Ultimately, the CVDs associated mortality could be reduced. In this manuscript, the design and implementation of a personalized healthcare system embodying a wearable ECG device, a mobile application, and a back-end server are presented. This system continuously monitors the users' ECG information to provide personalized health warnings and feedbacks. The users are also able to communicate with their paired health advisors through this system for remote diagnoses, interventions, etc. The implemented wearable ECG devices have been extensively evaluated and showed excellent intra-consistency (CVRMS ≈ 5.5 %), acceptable interconsistency (CVRMS ≈ 12.1 %), and negligible RR-interval errors (ARE < 1.4 %). To boost the battery life of the wearable devices, a lossy compression schema utilizing the quasi-periodic feature of ECG signals to achieve compression was proposed. Compared to the recognized schemata, this approach outperformed the others in terms of compression efficiency and distortion, and achieved at least 2× of CR at a certain PRD or RMSE for the ECG signals from the MIT-BIH database. To enable the capability of automated AF diagnosis/screening in the proposed system, a deep residual network (ResNet)-based AF detector was developed. For the ECG records from the 2017 PhysioNet CinC challenge, this AF detector obtained an average testing F1 = 85.10 % and a best testing F1 = 87.31 %, outperforming the state-of-the-art.


Instagram, famous for its easy picture and video sharing features, also has some other features, such as quiz, question, and poll, which can be used as English learning tools. The incorporation of Instagram becomes a valuable resource as most university students use Instagram. This study aims to explore those features and to investigate students' perceptions of Instagram as learning tools. The research participants are 50 students who speak English as a foreign language (EFL) studying at a university which applies English as a medium of instruction (EMI). The participants follow the researcher's Instagram account and are notified by email for every new post. They, therefore, can view and participate in those posts. The data is gathered from an online questionnaire. The results suggest that quiz is favored for its surprisingly effective function as a correction tool for common errors. In addition, cartoon post is favored as it provides funny and contextual use of the vocabulary which makes the vocabulary memorable. Hence, Instagram becomes effective English learning environment, which is supplementary to English classes, especially as an error correction and source of vocabulary input reaching massive number of students with only one post.


The discrete cosine transform (DCT) is widely used in all transform-based image and video compression standards due to its well-known decorrelation and energy compaction properties for typical images. Many fast algorithms available for the DCT optimize various parameters such as additions and multiplications but they are input independent and thus require the same number of operations for any inputs. In this paper we study the benefits of input- dependent algorithms for the DCT which are aimed at minimizing the average computation time by taking advantage of the sparseness of the input data. Here, we concentrate on the inverse DCT (IDCT) part since typical input blocks will contain a substantial number of zeros. We show how to construct an IDCT algorithm based on the statistics of the input data, which are used to optimize the algorithm for the average case. We show how, for a given input and a correct model of the complexity of the various operations, we can achieve the fastest average performance.


The anionic graft polymerization of lauryl methacrylate on the potassium alkoxide derivative of starch was studied. The yield of graft polymer increased with increasing alkoxide concentration. With increasing monomer concentration and with increasing temperature, the extent of homopolymer formation increased. The composition of the graft polymers depends on the reaction conditions; graft polymers having about 30–65% polylauryl methacrylate were obtained.


The definition of metonymy is typically known as semantic shifts within a domain or domain matrix;however,the existence of cross domains metonymic shifts challenges the typical definition of metonymy;Therefore,the present paper tries to examine metonymy as a prototypical category with part-whole contiguity in spatial domain as its core,and other metonymic patterns relate with it against three dimensions,namely strength of contact(going from part-whole containment over physical contact to adjacency without contact),boundedness(involving an extension of the part-whole relationship towards unbounded wholes and parts),and domain(with shifts from the spatial to the temporal,the spatio-temporal and the category domain),which is mainly based on the fruits of the researches conducted by Peirsman Geeraerts,and it will be done with the help of corpus collected from Chinese and English materials.


To talk about the history of transmission arts and limit it to the past one hundred or so years (coinciding with the electronicizing of a transmissive impulse) would be needlessly reductive. A sort of temporal provincialism. The art of transmission attends to more archaic, if not primal, origins and can extend to a future point unknown. However, in this short span of reflection, it would be equally perverse to extend the boundaries of transmission arts so that the term lacks termination, standing for both everything and nothing at once. Even though these all-or-nothing objects suit me fine, I will attempt some demarcation, enumeration, and qualification . . . although not, as brevity demands, elaboration.


This research was conducted to assess the quality of river water in the context of controlling water pollution in the TalawaanRiver in North Minahasa Regency, North Sulawesi Province. This research is a descriptive-quantitative research. The fieldresearch was carried out in the Talawaan River, North Minahasa Regency. Water quality measurement includes physicalparameters: TSS, and chemical parameters; BOD and COD were carried out at five monitoring points. The results showedthat the content of BOD, COD, and TSS in Talawaan River water met the water quality standards (Type B water). Thecharacteristics of the waste (BOD, COD and TSS), the concentration values of BOD, COD and TSS concentration values donot exceed the quality standard according to their designation. The potential for domestic waste pollution load reaches 1,495kg/day from a total population of 16,040 people. The status of Telawan River water quality is classified as "lightly polluted"based on the studied parameters; there are several other variables that were not included in this study, such as T-P, TotalColi, and Fecal Coli


Moderate deviation behavior of coding for discrete-memoryless channels is investigated. That is, we consider block codes whose rate converges to the channel capacity from below with increasing block length with a certain rate and examine the best 'sub-exponential' decay in the maximal probability of error. We prove that a moderate deviation principle (M.D.P.) holds for all convergence rates between the large deviation and the central limit theorem regimes, under some mild assumptions on the channel. The rate function of the M.D.P. is explicitly characterized.


The importance of soil and water loss assessment in ecological environment impact assessment was presented.All kinds of man made slope formed in road construction were sorted.According to the course of formation,slopes were divided into three types:cutting slope,embankment slope and hard ground surface.Soil and water loss types of slope were analyzed.Based on field monitoring,rainfall test and referring to fruitful researches,the ways of soil and water loss prediction were discussed.


Present study is aimed at assessment of groundwater quality of Gadap Town for drinking purpose using water quality index (WQI) technique. Gadap is located in the outskirt of Karachi city and mainly influenced by the agriculture activities. Groundwater samples (n = 22) were collected mainly from boring wells and a few through tube wells from variable depths (100-600 feet). The analytical results of water reveal occurrence of very high TDS (range: 466-3810; mean: 1402) and hardness contents (range: 250-2800 mg/L). On the other hand, pH varies (range: 6.9-8.1; mean: 7.5) within WHO guidelines (6.5-8.5) with a few samples showing turbidity. About one third of total collected samples (n = 8) were analyzed for qualitative determination of microbial contamination which are found positive, except one sample, indicating the sewage mixing. Major chemistry of groundwater is also found disturbed in terms of high content of Na (mean: 219 mg/L), K (mean: 15 mg/L), Ca (mean: 144 mg/L) and Mg (mean: mg/L 137). Similarly, anions varied in the order of Cl > HCO3 > SO4 > NO3. Although some parameters show the bad quality of water but Water quality index (WQI) value (16.18) indicates that the groundwater quality is suitable for drinking purpose. It is inferred from the present study that water quality is partly polluted due to anthropogenic activities mainly by sewage infiltration.


In this paper, lean premixed combustion on natural gas is studied in experimental
and numerical way. Experiments are done at the state-of-the-art 500 kW thermal power
combustion setup. The test rig resembles combustion chamber of gas turbine and can be
pressurised up to 5 bar absolute pressure. The experimental study are applied for
validation of numerical computations. For numerical calculations a hybrid approach
combining CFD and FEM methods is used. Mutual interaction between acoustic wave
propagation inside the combustion chamber and structural vibrations is studied applying
acousto-elastic model. During the CFD computations, pressure fluctuations created by the
flame in the combustion chamber, are calculated first. The results of the CFD are exported
then to the FEM code, where interaction between acoustic waves and wall vibrations is
resolved. To reduce the effect of numerical dispersion and dissipation of acoustic waves in
the CFD code, only the pressure recorded near the flame region is transferred. To simulate
acoustic waves next to the vibrating liner, the investigated model is equipped with acoustic
elements designed to recognize a structure on one side and a fluid on the other side of the
element. The frequencies at which thermo-acoustic instabilities may appear at given
operational conditions are predicted. Furthermore, a modal analysis to mark the hazardous
structural, acoustic and coupled modes and eigenfrequencies is performed. Computational
results are validated against experimental data. Results are in good agreement.


The study described in this text was undertaken to
test the hypothesis that reading comprehension items,
which elicit specific bottom-up and top-down
strategies, favour certain linguistic/cultural
groups. Although a variety of statistical methods
have been developed for flagging test items that
function differentially for equal ability examinees
from different ethnic, linguistic, or gender groups,
the standard differential item functioning (DIF)
detection procedures have not been very useful in
explaining why DIF occurs. To address this problem, a
confirmatory approach to DIF was used to determine
whether groups of reading test items, classified
according to a bottom-up, top-down reading strategy
framework, functioned differentially for equal
ability Arabic and Mandarin ESL learners. Analyses
revealed systematic group differences in two of the
bottom-up and three of the top-down reading strategy
categories. These results demonstrate the utility of
employing a theoretical framework for interpreting
group differences on a reading test that can be used
to assist ESL reading researchers, test developers,
and instructors in the development of technically
sound reading assessments.


This chapter is motivated by the need to escape the illusory perception of an incongruous implementation of information and communication technology policies in public administration processes in Africa. The problem is brought to light through an analytical distinction between e-government and e-governance. The analysis deals primarily with the impact of the new techno-economic regime, fostered by the development of information and communication technologies, on business and administrative structures, and shows that the conditions of implementation have varied from one political and policy environment to another. An inquiry into African ICT policies reveals a problem translated into the scantiness of African public administration structures in incorporating the conditions of technological change. The approach to solving the problem derives from the underlying distinction between e-government and e-governance. It shows that the efforts that produced thriving outcomes have tended to instill principled behaviors and actions in the restructuring of public administration structures.


Three sixteenth-century inscribed Bohemian chalices are known from the Carpathian Basin: one is from Kolozsvar (Cluj-Napoca, RO) and the other two are from the western Hungarian villages of Csonge ...


Abstract Several attributes have been used to label or legitimize the graphic novel as a relative of the comic book family. However, as single attributes, they are generally too blurry to cogently categorize certain long-form graphic works. The attribute 'complexity' bears enough potential to do so in the form of a typology, a graph functioning on two axes: horizontally, through a scalar continuum with the traditional (and possibly lengthy) comic book on the one extreme end and the graphic novel on the other; vertically, through a total of seven parameters which represent single aspects specifying graphic works by degree. Such a typology allows exclusive category assignments (e.g. 'graphic novel and not comic book') as well as differentiating assessments ('rather/not a traditional comic book/graphic novel').


Contemporary public administrations all over the world are exploring new service provision models that adhere to citizens needs. Recently, the "life-event" concept was introduced as a guiding metaphor for presenting and providing integrated public services. A life-event includes all public services that are related to a specific situation that citizens face. Although the concept of life-events is increasingly important for public administrations, the relevant scientific literature is limited. In this paper we present the main classes of an ontology for modeling life-events. It is anticipated that the use of this ontology will facilitate domain experts in public authorities to model life-events in a straightforward manner.


core. Besides, there is an aura of the primitive and underivative about a literary form we are used to considering as popular; we hardly dare profane it by dry, objective analysis. As the tradition of a community, it shares the anonymity of the latter. Seeking the traces of creative and tradition-conscious personages, we find only an amorphous mass of the unknown. No wonder that the riddle has been relegated back to prehistoric times, permitting us to conceal its problems behind a veil of mystery. Almost a century and a half has passed since the Brothers Grimm first turned with scholarly interest to the fairy tale. When we try to take a comprehensive view of the results which have by now been reached, we get the impression that the investigations have constantly gone around in a circle and have now returned to their point of departure. Have we asked the wrong questions? Have we tried to solve only parts of problems? At I any event, we can now talk about a &dquo;crisis&dquo; in fairy-tale scholarship,


The purpose of this thesis is to identify commonalities and differences in e-mobility development and strategies between conventional car manufacturers and emerging car manufacturers. The analysis is based on Porter's Five Forces, the Innovator's Dilemma, a total of 12 expert interviews from the industry, and additional research to support the analysis and interpretation of the findings. The findings show that conventional manufacturers have generally underestimated the disruptive nature of e-mobility and are forced to act quickly, especially with regard to battery technology. In addition, these companies choose different electrification strategies for their product portfolio. In general, there is currently a growing focus on the creation of a (digital) ecosystem outshining the importance of car production. This creates a new generation of automotive companies that are very similar to companies in the smartphone industry. Last but not least, emerging manufacturers are setting the trend for vertical integration in parts of the enterprise, especially in production and the supply chain, which impacts suppliers and conventional manufacturers.


This article interrogates the recent return of the discourse of the standard of 'civilisation' in international relations. Looking at the expansion of international society as an ongoing civilising project, it examines three important macro societal transformations of the international from a grand historical perspective. The classical civilising project, it argues, gives a particularistic interpretation and a truncated meaning to civilisation in international relations, while creating a pluralistic and functional order populated by Westphalian states. The globalisation of the modern sovereign order in the mid-20th century is equally a civilising project, as it redefines legitimate statehood and rightful membership in the making of a post-colonial international society. The current attempts at embedding democracy and human rights in the normative fabric of global international society, contentious and contested as they are, are an integral story of the expansion of international society 3.0, which is marked by a significantly expanded normative scope for making collective judgements of legitimate statehood and rightful state action. In bringing the expansion story up to date and giving it a hermeneutically different reading, the article suggests that as global international society resides in a multi-civilisational world, the civilising project as a form of inter-civilisational communicative actions will always have its place in the evolution of international society.


The vascular smooth muscle tone must be well-controlled to assure a perfect regulation of blood pressure. In this arena, we have two important intracellular messengers: Ca2+ and cAMP. Classically, the rise of intracellular Ca2+ within vascular smooth muscle cells starts a well-organized symphony which reaches into muscle contraction. Nowadays, we know that Ca2+ is an essential messenger that regulates vascular smooth muscle tone. Thus, a dysregulation of Ca2+ signalling may cause interferences on vascular tone.


The paper examines the activities of the Russian civil administration in Bulgaria and the bodies of the new administration made up of representatives of the Bulgarian people, and aimed at alleviating the plight of Bulgarian refugees during the Russo-Turkish war of 1877–1878. The research is based on published documents, letters and memoirs. The study reveals the reasons for the flight of the Bulgarians fearing retribution of the Turks, who returned to Lovcha (now Lovech) and the Rose Valley after retreat of the Russian troops. The author reveals what measures were taken by the Russian civil administration aimed at rendering assistance to refugees and their implementation by the officials of the Bulgarian administration.


This paper is concerned with stability properties of a Lur'e system obtained by interconnection of a general linear time-invariant block (possibly, infinite-dimensional) and a periodic nonlinearity. Such systems usually have multiple equilibria. In the paper, two new frequency-algebraic stability criteria are established by using. Popov's method of "a priori integral indices", Leonov's method of nonlocal reduction and the Bakaev-Guzh technique.


Abstract : Perceptions of the work environment were related to job attitudes and performance measures for personnel assigned to five outpatient health care clinics as part of a multistage, systematic investigation of organizational factors and practices that influence the delivery of health care. Specifically, the report presents (a) facility by facility comparisons and (b) differences due to the type of job (medical versus non-medical) and sex of the health care provider. Implications for health care delivery are discussed. (Author)


The scientific treatment of delinquent children.-During a period when both America and Europe have been forced to record an increase in juvenile crime, and when the environments which stimulate such behavior seem to be far too strong for the agencies operating in behalf of the child, a book with a hopeful interpretation of the situation is indeed welcome. The fact that such a book comes from an author of highest repute in this field of study adds a further element of encouragement to those concerned with child welfare. A recent book! by Dr. H. H. Goddard not only records the progress of the Ohio Bureau of Juvenile Research but also gives a most excellent discussion of the problems of the delinquent child. The operation of the Ohio bureau, which is explained in considerable detail, is made the basis for the discussion. Some indication of the extent of the bureau's service during its brief period of existence may be gained from the following summary.

Centre-periphery dichotomy can be regarded as one of the crucial issues in human geography and regional science. The definition of periphery is far from unambiguous due to its relative expression and its content. This is the reason why can significant number of studies be found focusing on the delimitation of central and peripheral areas. The revolution of computer technology and the rapid development of GIS cause the more and more extended usage of these techniques in the human geography as well. These related studies were categorised by their approaches – namely the locational or developmental centreperiphery concepts – and their GIS tools. Application of spatial parameters with extended datasets and complex GIS based calculations mean the most precise and complicated use of GIS and computer tools in the delimitation of peripheral (and central) areas.

The sorption of ammonia by polystyrene was investigated by pulsed nuclear magnetic resonance (NMR) relaxation techniques. The concentration of sorbed gas was determined from the intensity of the gas signal and analyzed by the dual mode sorption model. The relaxation data were used to examine the validity of assuming that the molecules exchange rapidly between sites and that the adsorbed species is relatively immobile. Both assumptions were found to be substantially correct although the possibility that the adsorbed species may have some small mobility (no more than 5% that of the faster moving molecules) could not be eliminated.


The profession of social work, like other professions, believes in certain values, values that represent formulations of pre ferred behavior and imply a usual prefer ence for specific means, ends, and conditions of life, often accompanied by strong feel ings.1 A commitment to these values has been enunciated by the social work profes sion through its Code of Ethics and state ments of practice.2 Inasmuch as members of the profession have the responsibility of communicating these value-oriented goals and objectives to professional neophytes through the educational structure and process, a study was undertaken that sought to answer the question: Do students enter ing graduate social work education express values different from those expressed by graduating students and/or experienced workers?


This study was conducted to determine the purposes for which corporations issued preferred stock and the types of characteristics attached to those issues. One hundred sixty-eight currently outstanding industrial preferred stock issues were researched. The most frequently given reasons for issuing preferred stock were to finance acquisitions and mergers, to reduce corporate debt, and for employee stock option plans. The majority of the preferred stocks studied were nonparticipating, cumulative, preferred over common as to assets, callable, convertible, and had voting rights.


The increasingly severe school violence has become an influential and notorious worldwide problem. The attribution of school violence determines the formulation of coping strategies. Unlike the analysis of family, psychological and social factors, long-term front-line work and follow-up studies have found that student violence's physiological factors in adolescence are more significant than other factors. The decisive factor leading to school violence among middle school students is the secretion of sex hormones during adolescence, so hormones mostly cause violence. Attributing school violence to "sex instinct" does not deny the role of education; on the contrary, it recognizes the crux of the problem and provides the possibility of finding effective prevention and intervention measures. Using dopamine to antagonize hormones provides a physiological basis for education and violence intervention. Strengthening physical exercise, carrying out activities where boys and girls are present simultaneously, and building a harmonious teacher-student relationship and a friendly campus environment effectively prevent middle school students from campus violence.

A tableau calculus for SHIQ has been known for some time, and it forms the basis for several highly successful implementations [2, 9, 10]. Extending this calculus to SHOIQ, however, was notoriously difficult due to an interaction between nominals, inverse roles, and number restrictions, which results in (partial) loss of the forest-model property for models of SHOIQ knowledge bases. In this paper, we analyze the problems that arise from this combination of features and present an overview of two solutions. The first solution, described in [4], extends the SHIQ calculus with an NNrule that extends the non-forest-like portion of a model with new individuals. Applications of this rule can be highly nondeterministic, however, and can substantially increase the size of the generated models, which can lead to inefficiency. We present an alternative solution based on a new NI-rule. Our approach does not introduce new individuals; instead, existing individuals are incorporated into the non-forest-like portion of the model. We implemented our solution in HermiT. As we discuss in [8], this approach seems to work well in practice.


Robust voice recognition (RVR) is essential for a robot to communicate with people. One of the main problems with RVR for robots is that robots inevitably real environment noises. The noise is captured with strong power by the microphones, because the noise sources are closed to the microphones. The signal-to-noise ratio of input voice becomes quite low. However, it is possible to estimate the noise by using information on the robot's own motions and postures, because a type of motion/gesture produces almost the same pattern of noise every time it is performed. In this paper, we propose an RVR system which can robustly recognize voice by adults and children in noisy environments. We evaluate the RVR system in a communication robot placed in a real noisy environment. Voice is captured using a wireless microphone. Navigation Strategy is shown Obstacle detection and local map, Design of Goal-seeking Behavior and Avoidance Behavior, Fuzzy Decision Maker and Lower level controller. The final hypothesis is selected based on posterior probability. We then select the task in the motion task library. In the motion control, we also integrate the obstacle avoidance control using ultrasonic sensors. Those are powerful for detecting obstacle with simple algorithm.


Abstract : Students of American history and students of international relations should be grateful to RAND for at last publishing Herbert Goldhamer's once Secret Memoir on the Korean War truce negotiations. Though the Memoir concerns only four months of negotiations that ran on for almost two years, it is a document illuminating not only the negotiations but the war as a whole. Perhaps more importantly, the manuscript provides insight into negotiation as a general process. Goldhamer's's lucid, clinical analysis of what he experienced and witnessed is reminiscent of Machiavelli or at least of Callieres. To recognize the value of the Goldhamer Memoir as a historical document, one needs some sense of common generalizations about the Korean War. Prior to the 1980s, most histories described Truman as having decided to intervene to defend collective security, not Korea. In a massive two-volume history of the origins of the Korean War, Professor Bruce Cumings has arrayed evidence showing that many of Truman's advisers thought South Korea important in its own right, partly as a shield for Japan, partly as a possible point of departure for rolling back Communism in Asia. In a comparably exhaustive general study of American foreign policy from 1945 to 1950, Professor Melvyn Leffler presents evidence that Truman himself had by that time come around to a view that any Communist accession of strength, anywhere on the globe, would jeopardize American national security.


If a person experiences or witnesses a traumatic event which is shocking, life threatening, humiliating, distressful and feels helpless, these conditions may happen in situations like crimes, fire, accident, death of a very loved person, sexual or physical abuse in some form, rape, terrorist attack, ragging in the college/ hostel etc. It causes changes in the brain leading to disturbance in thinking and emotional process leading to an anxiety disorder called as posttraumatic stress disorder (PTSD).


Estimation of the large deviations probability p/sub n/=P(S/sub n/>or= gamma n) via importance sampling is considered, where S/sub n/ is a sum of n i.i.d. random variables. It has been previously shown that within the nonparametric candidate family of all i.i.d. (or, more generally, Markov) distributions, the optimized exponentially twisted distribution is the unique asymptotically optimal sampling distribution. As n to infinity , the sampling cost required to stabilize the normalized variance grows with strictly positive exponential rate for any suboptimal sampling distribution, while this sampling cost for the optimal exponentially twisted distribution is only O(n/sup 1/2/). Here, it is established that the optimality is actually much stronger. As n to infinity , this solution simultaneously stabilizes all error moments of both the sample mean and the sample variance estimators with sampling cost O(n/sup 1/2/). In addition, it is shown that the embedded parametric family of exponentially twisted distributions has a certain uniform asymptotic stability property. The technique is stable even if the optimal twisting parameter(s) cannot be precisely determined. >

Abstract: According to various studies and investigations it is noticed that one of the major cause behind the road accidents is driver's drowsiness. Thus, countermeasure device is currently essential in many fields for sleepiness related accident prevention. Real-time driver drowsiness system alerts users when they are falling asleep. The project is designed to combat narcolepsy and microsleep. Microsleep strikes quickly. Users probably don't even realize that they are in the process of falling asleep, and almost certainly don't notice that eye blinking for longer than usual. The implemented project is mainly based on three components 1) Face and Eye detection: Performs scale invariant detection using Haar Cascade Classifier perform through a webcam. 2) Eye feature extraction: Eye features are extracted using Hough Circle and 3) Extract single eye and perform drowsiness detection on it. Whereas the complete system is implemented on Raspberry Pi which uses a webcam to monitor user's eye blink rate and average blink duration to detect drowsiness. The project is designed for a car safety which helps prevent accidents caused by the driver getting drowsy.


We propose a family of local CSS stabilizer codes as possible candidates for self-correcting quantum memories in 3D. The construction is inspired by the classical Ising model on a Sierpinski carpet fractal, which acts as a classical self-correcting memory. Our models are naturally defined on fractal subsets of a 4D hypercubic lattice with Hausdorff dimension less than 3. Though this does not imply that these models can be realized with local interactions in R 3 ?> , we also discuss this possibility. The X and Z sectors of the code are dual to one another, and we show that there exists a finite temperature phase transition associated with each of these sectors, providing evidence that the system may robustly store quantum information at finite temperature.
