The electronic media in Albania are among the most competitive and developed actors in society and the media performance in industrial and commercial terms, is greater than ever before. However, their role as dynamic social institutions is neglected and the understanding of their contribution to democratic values and principles through their professional approach is often limited. Due to such an important role to play in a democratic society, the bureaucratic regulation from outside is necessary, but not the only way to achieve democratic standards, in coherence with the European Union directives regarding electronic communications. This paper tries to argue that for this end, it is of great importance to look at the implementation aspects related to processes of self-regulation on the part of the electronic media operators as well as continual and functional dialogue with the public authorities of the electronic media from a public interest approach. For this purpose, the methodology used to conduct the research is basically the media agency analysis and textual analysis. First, this paper is going to identify the media instruments and media practices at work that inhibit self-regulation on the part of the media itself. Secondly, public discourses on the part of the public authorities of the electronic media shall be discussed. In theoretical terms, in the area of media studies, this stance is fueled by the phenomenological tradition and the socio-cultural tradition. From within these combined approaches it is of most importance to look at the way the information is produced in terms of codes of practices as well as the interpretations of the texts produced. This objective-interpretative stance with ethnographic traits in qualitative terms should enable this paper to retrieve results such as the negative correlation between a lack of a Journalistic Code of Practice and a possible self-regulation prospect in professional terms, but also flaws in institutional and democratic standards expected. The analyses at a theoretical level begin with Berger and Luckmann's theory of the "Social Construction of Reality", go on with the notions of the social production of news, tracing back from authors such as Herbert Gans on "Deciding what's news" or Michael Schudson on "The Sociology of news". Finally the paper shall propose ways to establish a dialogue among the involved actors in order to raise the democratic standards and values in terms of social and public responsibility taking, through a professional approach to questions of ethics and quality of the media content.


THE first volume of the series of the ' library of historical geography, published under the direction of Professor Beloch,' that of Sig. Colasanti on Fregellae, has already been noticed in the Classical Review, 1907, 207. Two more have now appeared, and several others are announced. The two works before us differ greatly in interest. In regard to the first it might easily be objected that there are other towns of far greater importance waiting their turn. Previous works on the subject are few, and the material is indeed scanty. After an introductory survey of the district (Pinna was situated E. of the Gran Sasso d' Italia, on the hills which descend from the Apennines to the Adriatic, 1437 ft. above sea level), a lengthy discussion as to the determination of the site of Pinna follows, the conclusion of which is, that the itineraries do not help to fix it, that classical writers hardly mention it, and that the similarity of names is the chief (but sufficient) argument for fixing it at the modern Penne. Of ancient remains, however, nothing is visible, and even the city walls are entirely mediaeval. The ancient city seems to have occupied only the site of the mediaeval town, and not the extension to the north, crowned by the castle—still less the hill on the S. as local writers have pretended—though even this can only be determined by a study of the mediaeval topography, inasmuch as the discoveries, if carefully sifted, amount to a single tomb of the Roman period found outside one of the gates in 1829, no finds from the town being recorded in the Notizie degli Scavi.

Endobronchial inflammatory myofibroblastic tumors (IMTs) rarely occur in children younger than 10 years of age and have intermediate malignant potential. A 7‐year‐old girl initially presented with pneumonia. After failing outpatient treatment, she re‐presented in status asthmaticus. Computed tomography showed a left mainstem endobronchial mass which was resected bronchoscopically. Pathology was consistent with IMT. Surveillance bronchoscopy identified a recurrence. Despite a left upper lobectomy, recurrence led to further treatment with celecoxib and argon plasma coagulation. Follow‐up bronchoscopy revealed complete resolution. She remains disease and symptom‐free at her six‐year follow‐up.

Classification is a supervised learning task based on categorizing things in groups on the basis of class labels. Algorithms are trained with labeled datasets for accomplishing the task of classification. In the process of classification, datasets plays an important role. If in a dataset, instances of one label/class (majority class) are much more than instances of another label/class (minority class), such that it becomes hard to understand and learn characteristics of minority class for a classifier, such dataset is termed an imbalanced dataset. These types of datasets raise the problem of biased prediction or misclassification in the real world, as models based on such datasets may give very high accuracy during training, but as not familiar with minority class instances, would not be able to predict minority class and thus fails poorly. A survey on various techniques proposed by the researchers for handling imbalanced data has been presented and a comparison of the techniques based on f-measure has been identified and discussed.


Vascular dementia( VD) is characterized by histopathological damage and progressive intellectual decline produced by cerebral ischemic hypoxia or hemorrhagic lesion. VD is the second most common form of dementia after Alzheimer's disease and its incidence is increasing with aging. It is generally accepted that brain ischemia-hypoxia is the main cause of VD,but the exact pathogenic mechanisms of VD is still not clearly demonstrated. Therefore,further confirming the etiology for VD and exploring the molecular and genetic mechanisms underlying have great significance for the diagnosis,prevention and treatment of VD in translational medicine.


Background: In India, as in the rest of the world, young people face several challenges to their well-being. One of the important challenges is air pollution; however, the impact of air pollution on adolescents' health is not fully explored. Objective: This article represents an attempt to explore impact of air pollution on adolescents' health through available width of information. Method: For this study we utilized the rapid review methodology that allows comprehensive review of the literature that describes urgent public health issue in the relatively short period. Result: It has been found that air pollution not only leads respiratory ailments of adolescents, but also has an impact on cardiovascular system, development of hyperactivity disorder, cancer, and many other conditions. Moreover, exposure to air pollution could increase susceptibility to chronic diseases later in life. This article can play a key part in raising the awareness of adolescents' health issues related to air pollution, initiate discussions and actions on preventing future damaging health effect for this subset of population.

A three-pulse degenerate four-wave-mixing experiment and its theoretical analysis reveal contributions of local field and biexciton effects to the nonlinear optical response of the two-dimensional exciton. Quantum beats with a frequency equivalent to the biexciton binding energy appear only for specific polarizations. Polarization-dependent spectrally resolved four-wave mixing shows an additional peak that is separated from the 1s heavy-hole exciton line by the biexciton binding energy. These experimental results are in good agreement with the optical selection rules of the theoretical model, providing evidence for biexcitonic contributions to the four-wave mixing.


The concepts of simulation based design and simulation as specification require support from appropriate computing tools. The Virtual Test Bed software continues to evolve to provide this support. Features of the software that support early-stage top-down collaborative design, in-situ and ex-situ execution of subsystem models at independent time steps, and variable levels of resolution are described here.


The skin and accessory structures perform a variety of essential functions, such as protecting the body from invasion by microorganisms, chemicals, and other environmental factors; preventing dehydration; acting as a sensory organ; modulating body temperature and electrolyte balance; and synthesizing vitamin D. The underlying hypodermis has important roles in storing fats, forming a "cushion" over underlying structures, and providing insulation from cold temperatures.


Next‐generation photodynamic therapy agents will minimize extraneous phototoxicity by being active only at the target site. To this end, we have developed a model system to systematically investigate the excited‐state quenching ability of a number of metalloporphyrins. Central metal ions that prefer four‐coordinate, square planar orientations (AgII, CuII, NiII, PdII, and ZnII) were used. Porphyrin dimers based on 5‐(4‐aminophenyl)‐10,15,20‐triphenylporphyrin and comprising both a free base porphyrin and a metalloporphyrin covalently linked through a five‐carbon alkyl chain were synthesized. The fluorescence and singlet oxygen quantum yields for the dimers were probed at 630 and 650 nm, respectively, resulting in the excitation of only the free base porphyrin and allowing a comparison of the quenching efficacy of each central metal ion. These results demonstrate that metalloporphyrins can serve as efficient quenchers, and may be useful in the design of novel light‐activated therapeutic agents.


Some safe and simple combined method of drainage and feeding after gastric operations has long been needed. First of all, the method should be comfortable and not irritating to the patient. Next, the method should drain any excess of retained secretions within the stump of the stomach in order to prevent vomiting, avoid gastric dilatation, and avoid excessive pressure on the line of anastomosis. The method should also drain any excessive secretions from both the afferent and the efferent jejunal limbs in order to prevent undue pressure on the closed duodenal stump and in order to be in a position to release pressure in the distal jejunal limb by suction if some paralytic ileus should develop. At the same time the method should permit all fluids and feedings to be given through the alimentary tract from the moment that the operation has been completed. A review of appliances heretofore used


Intrusion Detection is the act of detecting unwanted traffic/access on a network. It plays the central concept in overall network and computer security architecture. Intrusion Detection System (IDS) is installed software or a physical appliance that monitors network traffic and network resources which detects unwanted activities such as illegal and malicious traffic, misuse of network resources etc. Deep Packet Inspection (DPI) is most widely used in IDS. DPI analyses all data present in the packet and uses regular expression matching as a core operator. The complex string patterns such as attack signatures in DPI are flexibly represented using regular expression. In this paper, the basics of IDS, its components, its types, various network attacks, levels of packet inspection, implementation of DPI and various methods of DPI, features of regular expression and the working principle of regular expression with DPI are discussed. Thus the intrusion detection engine using deep packet inspection for regular expression matching greatly improves the speed of the intrusion detection and can also meet the performance requirements of the network.

We investigate the relationship between external volatility and the dynamics of the Brazilian Real exchange rate in the past decade. After endogenously allowing for this effect to change over time and controlling for a series of market-related variables, results show that the Brazilian economy is more affected by external markets movements today than in the recent past. On average, a change of one standard deviation in the VIX led to a depreciation of 0.4% in the Brazilian Real during the Great Recession. While emerging economies have become less volatile in the recent past, their currencies are still vulnerable to external volatility.


A combined experimental and theoretical Brillouin light scattering study of thermally excited spin waves in Fe/Co multilayers with three and five magnetic layers in direct contact is presented. A large number of discrete, well-resolved peaks, classified as either surface or bulk standing modes of the stack, appear in the measured spectra. The investigation of their frequency dependence on the magnetic field intensity and incidence angle of light allowed us to determine the complete set of magnetic parameters of the multilayer. The interlayer exchange coupling and perpendicular interface anisotropy are discussed in detail. The profiles of the dynamic magnetization associated with different spin wave modes are calculated and utilized for the calculation of the Brillouin scattering cross section. The result, compared with experimental spectra, allowed the determination of the ratio between the magneto-optic constants of Fe and Co.


Controlled frames in Hilbert spaces have been introduced by Balazs, Antoine and Grybos to improve the numerical output of in relation to algorithms for inverting the frame operator. In this paper we have introduced and displayed some new concepts and results on controlled fusion frames for Hilbert spaces. It is shown that controlled fusion frames as a generalization of fusion frames give a generalized way to obtain numerical advantage in the sense of reconditioning to check the fusion frame condition. For this end, we introduce the notion of Q-duality for Controlled fusion frames. Also, we survey the robustness of Controlled fusion frames under some perturbations.


A catalytic converter for reducing and purifying NOx in exhaust gas is provided with a carrier.  An ammonia adsorbing material is coated on that portion of the carrier which is on the exhaust inlet side and has a predetermined length, and a NOx reducing catalyst is coated on that remaining portion of the carrier which is on the exhaust outlet side.  Also, a first layer in which an ammonia adsorbing material and a NOx reducing catalyst are contained in a mixed state and a second layer in which a hydrolytic catalyst is contained are coated in that order on the surface of the carrier of the catalytic converter.  In a transitional phase during operation of an engine, NOx is reduced and purified using ammonia adsorbed on the ammonia adsorbing material.


Water morning glory, Ipomoea aquatica (Forssk.), is a widely used leafy vegetable throughout Southeast Asia and China. The fast growing plant produces high biomass with a soft watery tissue. This study focuses on the responses of water morning glory to water deficit under controlled conditions. Two cemented soil basins (8 m x 1 m x 1 m) under a plastic shelter were filled with soil material representative for Northern Thailand, taking care that the natural layering and bulk density was altered to the least extend possible. The original soil bodies were Regosol (a well-drained loamy sand developed on a middle terrace) from Mae Jo, Sansai District and Vertisol (a brown, clayey alluvial soil deposited on flood plain) from Mae Ai District. I. aquatica (cv. 'Reptan') was planted and three weeks drip irrigated keeping the soil close to field capacity (<-100 mbar) until complete soil cover. Each soil basin was divided into two longitudinal segments. On one segment of each soil basin irrigation was continued for control and on the other segment irrigation was stopped for monitoring water stress responses. Weather data were collected on site and matric potential was monitored with tensiometers. Stomatal resistance was determined once a day by a porometer (Decagon SC-1) and thermal images were acquired with an IR-camera (Infratec Variocam) at the same time. Crop water stress index (CWSI) was calculated as (TC - Tbase) / (Tmax - Tbase), where TC is the mean canopy temperature, Tmax is the upper threshold temperature of leaves where transpiration is suppressed by vaseline coating and Tbase is the temperature of water sprayed leaves and therefore the threshold for maximum evaporative cooling. After ten days of drought the plant material was harvested for determining above ground fresh and dry biomass. CWSI based on thermal imaging showed a higher correlation with matric potential as with stomatal resistance. It was possible to visualize the differences between well-watered and stressed plants by thermal imaging before visible signs of wilting started.


The subject matter of the paper is a philosophical analysis of the civilization-cultural development strategy Society 5.0. The strategy emerged from the idea of the Japanese government formulated in 2016. A critical analysis shows that this development program contains systemic contradictions and risks. Nevertheless, the idea seems to be achieving the goals of modern humanism in the conditions of information civilization development. The research methodology stems from the principles of consistency, complementarity, fractality and the dialectics of the concepts which are as follows: culture and civilization, linear and nonlinear development, etc. There is much evidence that today the integration of mankind has become global. The process leads to, firstly, the changes in the scales of human subjectivity, and secondly, the attitude of man to chance and need. All these characteristics are fraught with threats to the holistic existence of mankind, and the possibility of people's coming out of the crisis to the new levels of development. Private culture, which previously served as a powerful integrator of society, is losing the opportunity to carry out an ideological, and as a result, educational function in the conditions of an informational civilization. The transition of humanity from the monocultural to the multicultural way requires of relations between culture and civilization being based on the principles of complementarity. The construction of humanity as a self-organizing system is possible only through the management of civilization processes through culture, i.e., through the spiritual improvement of the human person. Evidence suggests that the principles laid down in the Society 5.0 development program do not meet these requirements. The program aims to implement the principle of positive feedback, as it tries to solve global problems of civilization with civilization practices. Theoretically, the achievement of harmonious relations between civilization and culture becomes possible on condition of the principle of complementarity. However, this principle also implies the rule of negative feedback


We proposed to periodically refresh the images stored in dynamic holographic memories by using an opto-electronic feedback loop. Readout of the images without loss of information is experimentally demonstrated in a photorefractive LiNbO3 sample.


Objective To investigate the lesion distributions and clinical manifestations of cerebral small vessel disease(CSVD) as well as the distribution- manifestation relationship through a retrospective analysis.Methods Medical records of 145 patients with MRI- confirmed CSVD were reviewed.The relationships of the MRI- revealed distributions of CSVD lesion with various clinical variables were analyzed.Results According to ratings in age- related white matter changes(ARWMC),the patients fell into three lesion severity- different groups:mild(n = 79),moderate(n = 47),and severe(n = 19).There were no differences in gender,history of stroke and TIA,diabetes,hypertension prevalence between the three groups(P 0.05).The average age was significantly different between groups(P 0.05).The incidence rates of mild cognitive impairment,stroke and TIA history,dizziness,vertigo,and gait disorder were significantly different in patients with lesions in the subcortex,basal ganglia,brainstem and cerebellum between groups(P 0.05).The incidence rate of urinary incontinence was not significantly different(P 0.05).Conclusion In CSVD,the lesion distributions are associated major clinical manifestations.A better understanding may help identify cognitive impairment and basal dysfunctions in the elderly,thereby resulting timely management.


Blockchain has been widely used in many fields such as bitcoin, smart contract, supply chain. However, because of the high requirement of computation and energy resource in mining process, blockchain application is restricted in mobile environment. In this paper, we introduce edge servers offered by Edge Service Provider into mobile blockchain network. Thus mining task can be offloaded from mobile devices to the edge server. Since there is competition among users, we propose an auction-based model for edge server resource allocation. Moreover, in order to maximize the revenue of all mobile users, we design a mechanism to achieve the allocation strategy and pricing rule for Edge Service Provider. Considering different resource demands, bids and usage time, we use Benders decomposition to get the dynamic resource allocation strategy. We evaluate the performance of the proposed auction model through extensive simulation. Results show that dynamic allocation can solve the resource allocation problem for Edge Service Provider and will get higher revenue with more winners than fixed allocation.

Profitable sheep production requires the application of certain well-timed management practices to ensure the overall well-being of the flock. Advances in breeding, lambing, feeding, and health management have given producers the tools to increase both the number and weight of lambs marketed annually. Sheep-budget analyses show that other than market price, the percentage of lambs marketed per ewe per year has the greatest impact on profitability of production. Conception rate, lambing rate, lambing percentage (lambs born/ewe lambing), and lamb survival rate are all important flock performance characteristics affecting the percentage of lamb crop marketed. Certain basic records must be kept to monitor flock performance. Without records, it is impossible to address those production and management practices that affect overall productivity. With records, the tools for decision making are in place for problem solving, identifying management priorities, and setting production and marketing goals. No single system of production is right for everyone. The ideal lambing season for a flock will depend on the available facilities, labor and management resources, genetics, pasture and feed resources, and the operation's marketing program. However, each system of production must emphasize those practices which enhance the overall well-being of the flock. Areas of critical importance that must be considered for every flock include internal parasite control, foot-rot control, and predator control. In many cases, the timing of the management practice is as important as the practice itself. Therefore, every sheep farm should have, at the very least, a simple set of working pens that facilitate the handling of sheep at critical times of the year. Too often, in the absence of a working facility, important tasks are ill-timed or left undone. The following schedule is divided into three parts. Section 1 includes jobs that should be performed during particular seasons of the year regardless of lambing date. Section 2 lists management practices that should be performed according to breeding and lambing dates. Section 3 gives some general recommendations that should be considered as they relate to overall flock health, facilities, breeding, and feeding management. Winter 1. Ewes up through 15 weeks of gestation should receive 4 lbs of a good quality grass/legume hay daily. 2. Ewes in the last 4 weeks of gestation should receive 4 lbs of a good quality grass/legume hay plus 1 lb of corn daily. 3. The highest quality hays should not be fed during gestation. Utilize average-to good-quality hays during the …


Rheology is one of the few methods which can be used for analyzing coagulation behaviour in concentrated dispersions. This is important for handling both theoretical and practical problems. For understanding the rheological behaviour of concentrated dispersions, experiments performed under pg conditions are useful. INTRODUCTION Dispersion rheology is one of the few methods which can teach us something on the coagulation behaviour of concentrated dispersions. Whereas dilute dispersion can be studied by quite a number of experimental methods with theoretical interpretations based on not too unsurveyable assumptions, rheology is the principal method available for concentrated dispersions. In the present paper, the relevance of dispersion rheology for dispersion science will be highlighted both from a theoretical and from a practical point of view. Two important fields can be distinguished: flow, and formation of particle networks. Both are important in practical as well as in theoretical respect: In practical respect, flow is important in slurry transport (e.g. transport of powder coal; application of paint). Generally, low energy dissipation during flow is aimed at, which means that viscosity should be as low as compatible with other restrictions on the system. An even more serious problem than excessive energy dissipation may arise when the system is prone to blocking of flow by sediment or floe formation; this is especially problematic in systems in which regular flow of a suspension is to be relied upon. Flow blocking in most cases is due to formation of particle networks, by coagulation and/or sedimentation. Such particle networks are formed e.g. during formation of soils, ocean OOOl-8686/93/$24.00 01993 Elsevier Science Publishers B.V. All rights reserved.


ABSTRACT In a recent paper, Nair et al. [Stat Pap 52:893–909, 2011] proposed Chernoff distance measure for left/right-truncated random variables and studied their properties in the context of reliability analysis. Here we extend the definition of Chernoff distance for doubly truncated distributions. This measure may help the information theorists and reliability analysts to study the various characteristics of a system/component when it fails between two time points. We study some properties of this measure and obtain its upper and lower bounds. We also study the interval Chernoff distance between the original and weighted distributions. These results generalize and enhance the related existing results that are developed based on Chernoff distance for one-sided truncated random variables.


aims the aims of this study were to validate the outcome of total elbow arthroplasty (tea) in patients with rheumatoid arthritis (ra), and to identify factors that affect the methods we searched Pubmed, meDLiNe, cochrane reviews, and embase from between January 2003 march 2019. the primary aim was to determine the implant failure rate, the mode of failure, and risk factors predisposing to failure. a secondary aim was to identify the overall complication rate, associated risk factors, and clinical performance. a meta- regression analysis was completed to identify the association between each parameter with the to 31.9°), pronation 74.0° (67.8° to 80.2°), 72.5° (69.5° 75.5°), and the mean postoperative Mayo Elbow Performance Score (MEPS) was 89.3 (95% 86.9 91.6). The meta- regression analysis identified that younger patients and implants with an unlinked design correlated with higher failure rates. younger patients were associated with increased complications, while female patients an unlinked prosthesis associated aseptic

People living with long-term functional limitations are very familiar with the influence of the environment, physical and economic structure, as well as cultural and social attitudes, on their lives. These factors can either restrict or support the individual's full participation in society or have a neutral impact. Our understanding of disability is difficult because of the influence of these environmental factors which can vary by participation area, by individual goals and choices, by type of action difficulty causing limitations and other characteristics of the person such as age, gender and race. Though these latter personal factors are seen as a separate area in the ICF (2001), the inclusion of attitudes in the environmental context does not necessarily allow for the separation of attitudes toward disability alone when the person's age, gender or race can confound social attitudes toward disability.


Most researches on celebrity endorsement concentrated on the endorser's credibility (including expertise and trustworthiness), attractiveness and congruence. In the investigation of Chinese consumers' evaluation on celebrity endorsement of the present study, a new factor named as "morality reputation" was found. The influence of this factor on the effectiveness of endorsement is also examined: consumers decline the evaluations to the endorsement when the celebrity endorser is thought of immoral. This influence is mediated by trustworthiness.


The paper is devoted to the study of specific features of flame dynamics in ultralean hydrogen-air mixtures in terrestrial gravity conditions. By means of numerical methods, it is shown that gasdynamic flows, which develop due to the buoyancy force acting on the hot combustion products, play a crucial role on the overall ultralean flame dynamics from the earliest stage after ignition and up to the large-scale motion of the developed flame. Immediately after ignition, convective flows determine the stability of flame kernel. It is shown that, on the one hand, despite the "superadiabatic" temperature of the flame products that is considered as one of the main stability factors of the ultralean flames in microgravity conditions, the influence of convective flows on the ultralean flames in terrestrial gravity conditions can alter flammability limits from that measured in microgravity. On the other hand, the propagation dynamics of the stable flame kernels is also mainly determined by the buoyancy forces. Rising velocity of the flame kernel in the ultralean mixture occurs to be much greater than the burning velocity and correlates well with estimations obtained for the bubble rising in liquid. Apart from the upward rising, the developed flame is shown to be expanding laterally; so, the complex large-scale flame structure is observed which could be a possible threat for explosion and fire safety for many industrial environments.


Regardless of the efforts of the European Union, freshwaters are in a state of environmental crisis. The Water Framework Directive has established a basis for the protection and restoration of European inland and coastal waters. In parallel, the Birds and Habitats Directives protect, maintain or restore, at favourable conservation status, selected species and habitats under a representative network of protected areas. Hence, the interplay between the EU regulations is of high scientific interest and practical relevance. In this article, Greece is used as a case study to explore whether anticipated synergies between the Water Framework Directive and the Nature Directives result in a better ecological status in the protected areas than in the non-protected ones. We investigated whether the ecological qualities that are defined by three biological quality elements (BQEs) differ between the WFD monitoring sites that are located within the Natura 2000 protected areas and those that are not. We identified a total of 148 river monitoring sites that are located within the Natura 2000 network, which corresponds to 30% of the WFD monitoring network. By employing ordered logit models for each BQE, we found that the ecological quality has the same likelihood to fail the WFD target of "good" quality for sites that are located within and outside the Natura 2000 protected areas. Our results confirmed our hypothesis that the EU directives have little synergy when it comes to restoration of ecological status of Greek running waters, according to the WFD.


The deliverable D2.1 focuses on identification and analysis of the information/knowledge related to complex products in GloNet, while aiming at the specification of a set of generic services for their provision to the stakeholders. Towards achieving this goal, a systematic process is defined and followed. In this process, we carefully aim at generalization, and not only focusing on a specific product in GloNet. Therefore, the systematic process starts with targeted analysis of the three planned complex products of GloNet, namely: (i) the PV solar plants, (ii) the intelligent buildings, and (iii) the future incubators. As a first step of the approach, the main entities common among these three products are discovered and extracted. These represent the elements, about which their information and/or knowledge needs to be stored and shared among different users in this environment, constituting the virtual Bag Of Information/Knowledge Assets (BOIKA) for each of the complex products. As a second step, the main groups of information users (including both stakeholders and software systems) that are common to different GloNet products are addressed. In the third step, a cross section between entities from the first step and users from the second step is established, and their specific access requirements and/or constraints are identified, aiming to verify their relevance as well as their comprehensiveness. In the fourth step, the results generated by the first step are analyzed and classified by their nature (/form) into the main categories of information/knowledge in the environment. Our main resulted categories include: atomic data, documents, and processes. The fifth step primarily analyzes and classifies the results which are generated in the second step, by their nature (/kind), into the main categories of users in the environment. Our main resulted categories include: Human user and software systems. In the sixth step it is discussed that in GloNet, access to information/knowledge from the virtual BOIKA repository, by software systems require them to be provided as web services. Furthermore it is discussed that access to information/knowledge by human users in GloNet requires them to be provided through user-friendly GUIs, where in turn, similar to the above, the software system of the GUI needs to access information/knowledge of the BOIKA, and thus also requires access through web services. Therefore, in the seventh and final step of the systematic approach, high level generic specification of the required web services for accessing through the cloud to the - atomic data, documents, and processes, related to GloNet products are provided. In the next step of the GloNet project, the specification of services which are provided in D2.1, serves as the base for their development, as will be addressed in D2.2


Objective To explore the effect and mechanism of lipopolysaccharide (LPS) on rat gastric mucosal cells line (RGM-1). Methods Injury of rat gastric mucosal cell line was examined by lactate dehydrogenase leakage. Western blot asssy was used to study the changes of COX-1 and COX-2. The level of PGE_2 was determined by radioimmunoassay. Results The result of LDH leakage showed that indomethacin could induce the injury of RGM-1 in a dose dependent manner and LPS could lessen it significantly (P0.05). Western blot assay showed that LPS could induce the expression of COX-2, and radioimmunossay indicated that the quatility of PGE_2 increased significantly (P0.05). Conclusion LPS has cytoprotective effect on RGM-1 via involving overexpression of COX-2.


In this paper I will look at the use of literature to support illustration students in the production of an artists book that seeks to question the position of the illustrator as a producer and author of work. I will discuss using literature as 'inspiration'/starting point for an artists book and show examples of works that incorporates ideas of adaptation/interpretation/new work, authorship, production/producer. Illustration practice and in turn what it means to be an Illustrator is in a period of questioning, seeking to redefine what this means. Having a curriculum that allows students to develop their own style and individual voice, along with having the choice to work across a range of media and processes be an illustrator that works in print, digital, animation, paint ink etc. places them in a pivotal position to explore the positioning of the Illustrator. As the arts and humanities are shaped and negotiated, subject to revision, the education of the Illustrator should seek to embed this understanding and implications in it's curriculum design. I conclude that students introduced to ideas of authorship, production and responsibility of establishing their role as an Illustrator, will have the ambition to be engaged the debate about Illustration. By the practice and dissemination of their work, along with entering discussion and debate they can seek, not to limit their concept of Illustration, but develop an encompassing definition of what it can be.


One's native tongue is learned from infancy through direct communication. Skills in foreign languages are usually acquired later and more formally through the language patterns of the native tongue. One conse quence is that the foreign language is per ceived through the framework of the native language. Equivalent structures and patterns may be transferred from one language to the other but those areas that differ or are idio matic can not be so handled, and they are likely areas of misunderstanding. The Japanese author writing in English, therefore, is more inclined to have difficulty with English patterns that vary from his own language. He may not always be aware of such areas of potential trouble because of his habits of perceiving English and the absence of critical, outside criticism. If such is the case, he should probably learn to recognize these problem areas and try to treat them on English terms rather than through the patterns of his own language. Otherwise, he will


A 48 year-old male patient presented with a 30 years history of psoriasis affecting his whole body including the scalp. His lesions had incompletely resolved during treatment with topical and systemic anti-psoriatic drugs (Retinoic acid, vitamin D3, methotrexate, steroid). He had once experienced a period without lesions for 1 month after PUVA therapy. He was hospitalized in our clinic 12 years ago for his upper gastrointestinal bleeding due to acetyl-salicylic acid use and was treated with proton pump inhibitors at that period. He had active psoriatic lesions during this hospitalization period, due to cessation of anti-psoriatic treatment one month ago. He received a 2 months course of omeprazole treatment after his upper gastrointestinal bleeding and his lesions had resolved. He did not come to follow-up visits for the following 11 years and then he again applied our clinic with dyspeptic complaints. His physical examination and laboratory findings were normal. We have learnt from his medical history that during these last 11 years he insisted on using proton pump inhibitors (omeprazole, lansoprazole, esomeprazole) for his psoriatic lesions but not for his dyspeptic complaints and without the advice of any doctor. He also reported that he also tried pantoprazole but could not get any benefit from it. We requested him not to use PPIs for a certain period of time to confirm the effect of PPIs on psoriasis. We observed 2 psoriatic lesions on tibia 7 days after his PPI withdrawal (Figure 1A, 1B). His lesions improved greatly after a 10 days period of rabeprazol administration (Figure 1C). His lesions completely resolved after 20 days. Any psoriatic lesion was developed during last 24 months.


Device independent I/O has been a holy grail to operating system designers since the early days of UNIX. Unfortunately, existing operating systems fall short of this goal for multimedia applications. Techniques such as caching and sequential read-ahead can help mask I/O latency in some cases, but in others they increase latency and add substantial jitter. Multimedia applications, such as video players, are sensitive to vagaries in performance since I/O latency and jitter affect the quality of presentation. Our solution uses adaptive prefetching to reduce both latency and jitter. Applications submit file access plans to the prefetcher, which then generates I/O requests to the operating system and manages the buffer cache to isolate the application from variations in device performance. Our experiments show device independence can be achieved: an MPEG video player sees the same latency when reading from a local disk or an NFS server. Moreover, our approach reduces jitter substantially.


AN International Seminar on Vocational Guidance for the Handicapped was held at the Hebrew University, Jerusalem, from August 22 to September I, 1960. under the auspices of the International Vocational Guidance Association. The 150 delegates from 15 countries gathered together to listen to lectures by eminent people from ail over the world. to discuss mutual problems. and to visit centres for training and rehabilitating the handicapped in Israel. The delegates were drawn from various disciplines dealing with this problem--medical, educational, psychological, employment and the wide field of social u.ork. The three delegates from Great Britain were Mr. W. G. Brown, Senior Psychologist with the Ministry of Labour's Youth Executive, Miss M. 0. Davies, Senior Youth Employment Officer. who co-ordinates the services for handicapped young people in the London area, and Miss M . R. Morgan. Employment Officer of the National Spastics Society. Visits were paid to training centres and sheltered workshops for different types of handicap, and.delegates were impressed by the amount of work that had been achieved in a comparatively short space of time. The problems facing Israel are many and varied, for they have to deal not only with their own handicapped young people but also with the many aged and disabled refugees who have been pouring into the country from all over the world. bringing with them their different cultures and social problems. Great interest was shown in the work done in England in all fields, particularly by delegates from Israel, and many asked to receive medical and other literature published by the National Spastics Society. During the seminar six main topics were covered very thoroughly, by lectures (given in different languages, but with simultaneous translation), by discussion in small working groups, and by the presentation of the summaries to the main conference. The introductory talk, given by Prof. Donald Super of Columbia University, covered the Whole-Personality Approach to Rehabilitation. Professor Super pointed out that any counsellors working with the handicapped have both professional and personal limitations, and it is not easy to dissociate ourselves from preconceptions and misinterpretations of fact when trying to reach a fair appraisal of a handicapped person. Each professional member of the team-vocational counsellor, social worker, physician and psychologisttends to look at the client from his specialist point of view and to exaggerate his side of the problem. 'But when these and other rehabilitation specialists work together, either as members of a team or in consulting capacities, the limitations and biases of the individuals may be surmounted. The pooling of information and the airing of differing points of view may lead to the formulation of a picture of the client which approximates the reality.'


The invention provides a method for realizing media caching, which comprises the following steps: a media buffer is arranged; a client sends a service request to a media server MRF by a core IMS; the MRF obtains information including the address of the media buffer and sends a service request response including the MRF address or the address of the media buffer to the client by the core IMS; the client sends a content request to the MRF or the media buffer according to the received MRF address or the address of the media buffer; after receiving the content request sent by the client, the MRF or the media buffer provides content of request to the client. The invention also discloses systems corresponding to the two methods, which respectively comprise the client, the core IMS, the MRF and the media buffer. The invention also discloses two media buffers. The method for realizing media caching of the invention can realize media caching in an IMS network environment.

An increasing body of research is showing a link between osteoporosis and cardiovascular disease. The associations are complex and, in some cases, not yet fully understood, but the clinical implications are that healthcare professionals need to consider their osteoporosis patients as having as high a risk for heart disease as those with type 2 diabetes mellitus.


A discharge tube (17) comprises a glass tube (30), a cap (40) disposed at the end of the glass tube (30), and lead wires (32a, 32b) formed at the end of the glass tube (30). The lead wires (32a, 32b) are brought into contact with the cap (40) while bent inside the cap (40) and can receive electric power supply from outside via the cap (40). By bending the lead wires (32a, 32b) constituting non-light-emitting portions of the discharge tube (17), the apparent lengths of the lead wires (32a, 32b) can be reduced, and the proportion of light-emitting-portions in the entire length of the discharge tube (17) can be increased.


Background Chronic venous insufficiency (CVI) is a condition caused by retrograde flow of venous blood that is attributed to several factors, the most important of them is damaged venous valves. Recent studies have suggested that the popliteal-vein (PV) diameter has a vital role in the vastness of lower-limb CVI. Doppler ultrasound (DUS) is considered the mainstay noninvasive imaging modality for the diagnosis of peripheral vascular disorders. Objective The target of our study was to point out the relation between the clinical severity of primary CVI and PV condition evaluated by DUS. Patients and methods In total, 50 limbs of 25 consecutive patients (14 women and 11 men; age range, 25–85 years) with clinical diagnosis of CVI were graded according to the Clinical Etiological Anatomical Pathological classification and then examined by DUS for estimation of PV diameter and venous reflux. In each limb, the clinical grade of CVI was then compared with the DUS findings. Data were collected and analyzed using SPSS, version 20 and statistical significance was set at P value less than 0.05. Results The mean PV diameter was 1.3 cm. No reflux was observed in limbs with PV diameter less than 6 mm. Reflux was detected at the femoropopliteal junction in 22% of the examined limbs with the highest frequency at PV diameter more than 9 mm. There was a direct association between the PV diameter and the clinical severity of CVI. An increased PV diameter was affiliated with higher frequency and velocity of reflux at the femoropopliteal junction, which were consequently associated with higher Clinical Etiological Anatomical Pathological grades. Conclusion There was a significant correlation between the clinical grades of CVI-enhanced and DUS-evaluated PV condition. The degree of the increase in the PV diameter can reflect the severity of CVI.


The substrate for wide, and forming a shallow first cavity comprising a first portion and a narrow, deep second portion is provided. A first portion of the cavity extending inside the substrate from the front surface of the substrate is filled with a sacrificial material. The second portion is extending more deeply into the inside of the substrate from the first portion. Device structure is fabricated on a sacrificial material. Release etchant is introduced from the backside of the substrate via the second portion of the cavity to remove the sacrificial material of the following structure from the first portion of the cavity. The removal of the sacrificial material under the inlet to the release etchant from the back surface of the substrate assembly on the second portion of the cavity from the first portion of the cavity makes it possible to implement the release etching without exposing the device structure to the release etchant. This makes it possible to include a device structure of a material having a low etch selectivity to the sacrificial material.


By coupling peptides with DNA tags (i.e., 'barcodes'), it is now possible to harness high-throughput sequencing (HTS) technologies to enable highly multiplexed peptide-based assays, which have a variety of potential applications including broad characterization of the epitopes recognized by antibodies. While the processing of HTS data, in general, is already well supported, there are very few software tools that have been developed for working with data generated in these highly-multiplexed peptide assays. In order to fill this gap, we present PepSIRF (Peptide-based Serological Immune Response Framework), which is a flexible and comprehensive software package designed specifically for the analysis of HTS data from highly-multiplexed peptide-based assays.

Financial support by Research Department, Rajaei Heart Centerl, Tehran, Iran Abstract: Background: Narcotics are the most common drugs that have been used after cardiac surgery. Everyone knows that their side effects including respiratory depression, hemodynamic instability, and nausea, vomiting and itching are dose dependent. Magnesium is both N Methyl D Aspartate (NMDA) – receptor and calcium receptor antagonist and can modify important mechanisms of nociception. The purpose of this study was to investigate the effect of magnesium sulfate on pain score and reducing narcotic requirement in coronary artery bypass surgery patients. Methods: In a randomized, double blinded, placebo-controlled trial One hundred and eighty five patients (105 male and 80 female) undergoing elective coronary artery bypass graft surgery were studied. Mean age were 58+_11 (from 24 to79 years).We enrolled them in two groups randomly. Group1 received magnesium sulfate as an IV infusion 80 mg/kg during one hour after induction and the second group received the same volume of normal saline as placebo. During the postoperative period, Morphine requirement and pain score (visual analogue scale: scaled as 0 to 10, 0=no pain and 10= worst possible pain) in 6, 12, 18, and 24 hours were recorded and documented. Results: There were no significant differences between two groups with respect to baseline data. In MG group, only 30 patients (32%) needed to receive Morphine Sulfate , but in placebo group, 75 patients (83%) needs some doses of Morphine Sulfate (p value < 0.001); The odds ratio showed that MG could strongly prevent the needs for receiving opioid analgesics for controlling of the pain. Conclusion: Intra operative use of magnesium sulfate can reduce receiving opioids after (CABG) operations.


The present study proposes a novel optimization strategy (NOS) for quasi-steady algorithms to optimize the initial error in the fast calculation of conjugate heat transfer (CHT) simulations. In this approach, the change in Nusselt number at the fluid–solid coupling interface is dynamically monitored, and the update of the flow field is turned off according to a given Nusselt variation standard to speed up the solution of the transient temperature field. The NOS has been applied to problems of convective heat transfer in solid parts with internal heat sources. The feasibility of NOS is first verified by using an undisturbed boundary example, and the results show that the optimization strategy reduces the initial error by 92.3% compared with the quasi-steady algorithm, and the calculation time is reduced by 50% compared with the traditional coupling algorithm. The NOS is then combined with the quasi-steady algorithm, and boundary transient disturbances are added to the case. The results indicate that the computational time for NOS and the quasi-steady algorithm is 2.6 and 2.9 times greater than that of traditional algorithms. Nevertheless, NOS significantly optimizes the relative error of the quasi-steady algorithm by 97.3% during the initial computation phase.


ABSTRACT This essay works with the idea of absence and rejection of "failed" bodies/masculinities within Xhosa traditions of creating men and manhood negotiation and Morell's assertion that boys are culturally unable to choose masculinity scripts that please them. The essay thinks through these two ideas and discusses how Mgqolozana's novel, A Man Who is Not a Man, sutures failed bodies into "traditional" Xhosa manhood creation and definitions. It consequently demonstrates that Xhosa young men are capable of carving traditions of manhood creation that are aligned with ulwaluko but not limited by traditionalism. The essay concludes that ten years after its first publication, the novel continues to provoke debate on the reconfiguration of Xhosa masculinity creation traditions through the use of a pseudo-autobiographical narrative voice, which simultaneously incorporates failed bodies into traditions of men-making and puts emphasis on care work as a cornerstone in the construction of the ulwaluko ritual.


It is well recognised that patients differ in the clinical presentation of atrial fibrillation (AF), ranging from the typical symptom of palpitations, atypical symptoms in others and a substantial that are asymptomatic. Whether the different patterns of presentation are associated with differences in outcomes is not known. The aim of this study was to evaluate the prevalence and the prognostic implications of lack of palpitations among patients hospitalised with AF in a large prospective registry.


Present study involves preparation and evaluation of floating microspheres with piroxicam as model drug for prolongation of gastric residence time. The microspheres were prepared by solvent evaporation method using polymers hydroxypropylmethyl cellulose and ethyl cellulose. The shape and surface morphology of prepared microspheres were characterized by optical and scanning electron microscopy, (SEM) respectively. In-vitro drug release studies were performed and drug release kinetics was evaluated using linear regression method. Effects of the stirring rate during preparation, polymer concentration and dissolution medium on the size of microspheres and drug release were also observed. Prepared microspheres exhibited prolonged drug release (>8 h) and remained buoyant for >10 h. The mean particle size increased and the drug release rate decreased at higher polymer concentration. It was observed that there is no significant effect of the stirring rate during preparation on drug release was observed. In-vitro studies demonstrated diffusion- controlled drug release from the microspheres.

Submitted for the MAR12 Meeting of The American Physical Society Ultrafast exciton energy transfer from giant nanocrystals to layered J-aggregate films ASJA RADJA, HUE NGUYEN, Department of Physics, The University of Texas at Dallas, Richardson, TX, 75080, JENNIFER HOLLINGSWORTH, Chemistry Division and Center for Integrated Nanotechnologies, Los Alamos National Laboratory, L, ANTON MALKO, Department of Physics, The University of Texas at Dallas, Richardson, TX, 75080 — The integration of organic and inorganic materials at the nanoscale offers the possibility of developing new photonic devices that could combine the advantages of both classes of materials. Particularly interesting for such applications is a new class of core/shell CdSe/CdS nanocrystals (NQDs) with large number of shell monolayers (MLs) that are photostable, non-blinking and have an advantage of suppressed non-radiative Auger recombination leading to the existence of bright multiexcitonic (MX) states. However, due to large MLs thicknesses, the extraction of charge through such shells may pose considerable problems. In this work we studied hybrid structures composed of "giant", (#ML>10) CdSe/CdS NQDs anchored on top of thin layers of strongly absorbing J-aggregates (JA) of cyanine dye (TDBC). We performed time-resolved and steady-state photoluminescence (PL) measurements to quantify the excitonic energy transfer (ET) rates from the gNQDs to JA layer. By varying temperature (from RT to 80K) we observed change in ET rates in accordance with the overlap integral between NQD PL emission and JA absorption. In all cases, ET transfer rates exceeded 99%. Hence, we foresee the utilization of gNQDs in applications in hybrid systems based on energy transfer.

Graphene nanoelectronics potential was limited by the lack of an intrinsic bandgap[1] and attempts to tailor a bandgap either by quantum confinement or by chemical functionalization failed to produce a semiconductor with a large enough band gap and a sufficient mobility. It is well known that by evaporating silicon from commercial electronics grade silicon carbide crystals an epitaxial graphene layer forms on the surfaces [2]. The first epigraphene layer to form on the silicon terminated face, known as the buffer layer, is insulating. It is chemically bonded to the SiC and spectroscopic measurements [3] have identified semiconducting signatures on the microscopic domains. However, the bonding to the SiC is disordered and the mobilities are small. Here we demonstrate a quasi-equilibrium annealing method that produces macroscopic atomically flat terraces covered with a well ordered epigraphene buffer layer that has a 0.6 eV bandgap. Room temperature mobilities exceed 5000 cm2/Vs which is much larger than silicon and 20 times larger than the phonon scattering imposed limit of current 2D semiconductors. Critical for nanotechnology, its lattice is aligned with the SiC substrate, it is chemically, mechanically, and thermally robust, and it can be conventionally patterned and seamlessly connected to semimetallic epigraphene making semiconducting epigraphene ideally suited for nanoelectronics.


Staphylococcus aureus is one of the common causes of infective endocarditis (IE). IE can present with various neurological complications such as stroke, brain abscess, and meningitis, the mortality rate can be very high in such cases.


Surface phonon spectra in ultrathin α-Al2O3 films prepared on metallic substrates show excitation of modes in the frequency range of the surface dipole forbidden ω_-branches according to the dielectric theory of EELS. We compare calculations of the z-polarisation of the FuchsKliewer modes based on lattice dynamics with dielectric theory and semi-microscopic results for a simple NaCl lattice type thin film in the limit of k→0 appropriate to the dipolar-scattering regime. The form of the primary-beam-energy-dependence of the ω_-branch in thin α-Al2O3 films is similar to the lattice dynamics prediction but is of much greater intensity. While the strong k-dependence may be attributed in part to significant z-polarisation of the ω_-branch, mixing with microscopic surface modes seems likely.


This paper presents a novel approach to image-based visual servoing by making motion plans directly in the image plane. By skipping the step of transferring image features back to robot pose, we are able to utilize the image features for a direct and fast motion planning solution. Standard visual servoing techniques can then be applied to tract the given trajectory. In this paper, we have applied the idea to 2D and 3D (kinematic) motion planning and discussed the mechanisms for taking advantage of surplus features and incorporating other image-based constraints, such as that the targets always remain in the field of view.


Brain computer interface studies required recording of a physiological response of a subject to exhibit relevant information. This extracted information can be used to perform an action and the amount of the information plays a significant role in the determination of brain computer interface (BCI) performance. The use of improved experimental paradigms as well as measuring the brain responses using electroencephalogram (EEG) is the most common approach for the BCI studies. In this study, the classification of the ongoing brain activity occurring as response to the four shapes is managed and reported. We applied Fourier transform to obtain the frequency spectrum regarding the one second time series of each channel with a time overlap of 50% to the feature set of each stimulus type. Four machine learning classifiers are implemented, and in the concept of the classification, (delta, theta, alpha, beta, and gamma) band power values for one second period constituted the feature set, resulting in a total of 315 features. Among the four ML classifier Quadratic Discriminant 87.1% recorded the highest accuracy.


Protein kinase C (PKC) isozymes are tightly regulated kinases that transduce signals from receptor‐mediated hydrolysis of membrane phospholipids. Whereas loss‐of‐function mutations in PKC are associated with cancer, germline mutations that enhance the activity of one isozyme, PKCα, are associated with Alzheimer's Disease (AD). Here we show that introducing a highly penetrant AD‐associated variant of PKCα (M489V; increases catalytic activity by 30%) into a mouse model accelerates brain pathogenesis and results in a cognitive defect compared to wild‐type mice. Specifically, behavioral studies reveal a cognitive impairment in mice harboring this mutation compared to WT mice at 12 months of age, as assessed by performance on a Barnes Maze test, which measures spatial learning and memory. Additionally, the presence of the PKCα mutation in an AD mouse model overexpressing the amyloid precursor protein with the Swedish mutation, significantly exacerbated the cognitive decline as early as 6 months of age. To better understand the molecular basis for the cognitive defect, we analyzed the phosphoproteome and synapse morphology of mice harboring the PKCα M489V mutation. Analysis of the brain phosphoproteome of PKCα M489V mice vs wild‐type mice identified a variety of substrates with altered phosphorylation including known substrates of PKC involved in synaptic depression. Phosphorylation of one such protein, MARCKS, was increased both in mice harboring the PKCα mutation as well as human brains from patients with AD. Analysis of spine density revealed a modest (approximately 10%) but highly significant reduction in the number of spines per micron in the homozygous M489V mice compared to the wild‐type mice. Reduced spine density is consistent with the enhanced phosphorylation of MARCKS observed in brains from the M489V mice. In summary, this work reveals that a single amino acid change in the catalytic domain of PKCα is sufficient to cause increased phosphorylation of PKC substrates, neurite degeneration, and cognitive decline. These data strongly support inhibition of PKCα as a potential therapeutic target in AD.


While teacher educators agree that teaching is a profoundly moral activity, little attention has been placed on the moral perspectives about teaching and learning of those entering the teaching workforce. As a way of illustrating the importance of helping both future teachers become aware of their own moral compasses and teacher educators to understand ways in which such knowledge can support their students, I use methods of qualitative inquiry to explore the life history of one European American preservice elementary teacher in the USA. In recounting the events of her life, Rachel Rosenberg demonstrates how she uses her own life experiences to frame the moral aspects of her future role as a teacher and especially her perspectives on literacy teaching and learning. The methods used here to elicit and analyse Rachel's story can be useful to teacher educators who want to understand how the moral perspectives embedded in teachers' stories influence the ways in which teachers approach and enact the work of teaching.


The Coteau Properties Company (Coteau) operates the Freedom Mine, a large surface coal mine in western North Dakota. About 5,000 acres have been reclaimed since 1986. Through partnerships with local farmers and ranchers, the mining company has developed a program to expedite a return of reclaimed cropland and prairie to full economic use. Reclaimed croplands are being farmed immediately after topsoil is spread, rather than following the common industry practice of planting a hayland crop and breaking it several years later. This reduces seeding and tillage costs and allows local producers to manage a quick economic return on reclaimed lands. It also provides crop yield data earlier in the bond liability period. Cattle grazing is used as a vegetation management tool as soon as grass stands are established. This also provides a local economic benefit in addition to reducing management costs. Grazing is an essential element in managing reclaimed stands for diversity. The mine works closely with local producers in developing annual farm plans that will satisfy the ultimate goal of final bond release. Amenities provided to enhance land use include all-weather section line roads, designed field a roaches, shelterbelts, fencing, stockponds and stockwater tanks, and livestock corrals.


Myopericytoma is a rare tumour which typically presents as a benign lesion that mimics features of other more common vascular tumours and malformations. We present a case of a symptomatic diffuse myopericytomatosis of the left abdomen presenting as multiple subcutaneous vascular tumours detected on ultrasound and treated with ultrasound‐guided sclerotherapy.


—Currently, Connected Dominating Sets (CDS) have been widely used to serve as virtual backbones for the topology control of wireless ad hoc networks. Lifetime is one of the most important characteristics of a wireless ad hoc network since mobile nodes are equipped with energy-limited batteries. In this paper, we propose two CDS construction algorithms, CDS-LL and Extended CDS-LL (E-CDS-LL), to prolong lifetime of a CDS-based wireless network. The CDS-LL algorithm trades CDS size for lifetime by a tunable parameter  . When  moves from 1 to 0, a CDS will be constructed with more energy-rich nodes. In the simulation, we show that when  is 0.8, the CDS-LL algorithm increases lifetime at least 6 times through sacrificing around 8% of size. Moreover, since CDS nodes consume more energy than non-CDS nodes, the E-CDSLL algorithm balances energy consumption of wireless nodes via dynamically selecting energy-rich nodes with the CDS-LL algorithm to reconstruct the CDS before the CDS is disabled. Simulation results show that network lifetime can be prolonged by 66% on average through the E-CDS-LL algorithm compared with the CDS-LL algorithm.

A computer program was used for studies of the disturbed zones around bodies in flowing plasmas, particularly spacecraft and their associated sheaths and wakes. The program solved a coupled Poisson-Vlasov system of nonlinear partial differential integral equations to obtain distributions of electric potential and ion and electron density about a finite length cylinder in a plasma flow at arbitrary ion Mach numbers. The approach was applicable to a larger range of parameters than other available approaches. In sample calculations, bodies up to 100 Debye lengths in radius were treated, that is, larger than any previously treated realistically. Applications were made to in-situ satellite experiments.

Nutbearing plants of the ARIPG world collection pis-tachioes cultivars are studied. It is established that the Central Asia forms are nonresistant to a number of plant diseases and pests as it is evident from the collection. The most persperctive are the Azerbaijan forms (Abshiron), though these forms are noted for poor openess of the nutshell.


This paper introduces the Scaled Relative Graph (SRG): an intuitive and powerful tool that radically simplifies the monotone operator theory and some convex analysis. It creates a two-dimensional graphical signature of an operator's action, which explain the convergence behaviors of many algorithms in convex optimization via a simple, unified, rigorous approach. It provides visual intuitions behind many existing theorems about operators and makes it easy to prove new theorems (as this paper will do). Sitting at a high level of generality, monotone operator theory abstracts the components of a convex optimization algorithm as operators and relates the convergence behavior of the algorithm to the properties of these operators. However, this extremely useful theory has a high barrier to entry as the definitions and results are expressed in terms of norms, inner products, and inequalities, which can be unintuitive. The SRG makes monotone operator theory much more intuitive. To illustrate the difficulty, consider the following result.


Depletion models describe the behaviour of predators (or herbivores) distributed between patches of prey (or vegetation) in the absence of interference. We show how such a model can be used to describe the distribution of two herbivore species in relation to the vegetation. The Yare Valley, Norfolk, England, is the major wintering site for bean geese in Britain and the population is of considerable national conservation interest. Within the Yare Valley, Buckenham marsh has traditionally been an important site for this species. Field data on habitat preference, depletion rates and seasonal changes in the numbers of both wigeon and bean geese were incorporated, along with data on grass productivity, into a depletion model


The objective of the Smart Rollator project is to enable health care monitoring and quantify rollator usage by embedding electronic sensing and recording. This thesis examines two sensor systems for the Smart Rollator: the electrocardiogram and speed/distance. A novel ECG amplifier, designed specifically to interface two gel-less electrodes, is introduced. The objective was to develop a circuit with performance sufficient to extract heart rate information reliably using digital signal processing techniques. A prototype system is built and evaluated. Results demonstrate that this circuit may be suitable for the Smart Rollator application. A previous version of the Smart Rollator included the ability to monitor movement by sensing wheel rotation. A new design, in addition to measuring absolute distance travelled, measures net distance. An empirical design process is described to establish the best mounting distance of the sensors from the plane of the wheel, as well as the best spacing between sensors.


The CO+(A2 Pi to X2 Sigma +) and CO2+(A2 Pi u to X2 Pi g) fluorescence produced by impacting CO and CO2 with synchrotron radiation of wavelength in the 175-750 AA region was investigated and the production cross sections were measured. For primary photon wavelengths longer than 630 AA, the fluorescence cross sections show structure at the positions of the Rydberg series for both gases. For primary photon wavelengths shorter than 500 AA, the cross sections decrease monotonically with the wavelengths. The present measurements are compared with the various results reported by previous authors.


Several different techniques for the extraction, amplification and sequencing of mtDNA were investigated, in an attempt to find a rapid, robust and reliable method of acquiring sequence information from human mitochondrial genomes. Optimal results were obtained following two rounds of symmetric, nested PCR. The subsequent double-stranded, biotinylated, DNA products were immobilised on magnetic beads and sequenced using Sequenase® T7 DNA polymerase, in conjunction with either dye-labelled primers or dye-labelled terminators and an automated sequencer (Applied Biosystems). In this manner, mtDNA from 10 unrelated British Caucasian and 114 unrelated Afro-Caribbean blood samples was extracted, amplified and directly sequenced. Sequences of approximately 400 nucleotides were obtained, in both orientations, from two hypervariable segments within the non-coding region of the mitochondrial genome. The sequences were then assembled, analysed' and compared; to an external reference sequence (Anderson et al, 1981), to each other (within and between population) and to other published data sets. Comparison to a reference sequence (Anderson et al, 1981) showed that, for each population, both hypervariable regions sequenced were polymorphic to similar extents. The nucleotide sequence present at the time of population splitting was also inferred from further comparisons to the reference sequence (Anderson et al, 1981). A total of 94 different sequences were observed in the Caucasian population, with an average nucleotide diversity of 1.0%. In the Afro-Caribbean population, however, a total of 105 different sequences were observed, with an average nucleotide diversity of 1.75%. The higher nucleotide diversity observed in the Af roCaribbean data, along with a greater proportion of significant race specific positions, suggested an earlier evolutionary origin for this population. Phylogenetic analysis of the populations was carried out using PAUP (Swofford, 1991) and PHYLIP (Felsenstein, 1995). However, due to the non-clustering of samples known to have the same sequence, it was concluded that any inferences formed from the analysis of resultant genealogical trees had to be viewed accordingly.


In wireless sensor networks (WSNs), the sensor nodes collect data from the target area and send it to the base station through a multi-hop connection. As a result, high energy dissipation of the sensor node may occur. Some times failure of nodes on large scale create partitions in the network. Also, the presence of obstacles is the reason for the coverage gap in networks. The introduction of mobile nodes has been measured to be a worthy approach to significantly decrease the energy dissipation of the static sensor nodes. This job is realized by considering the route through which the mobile collectors move to collect data from the sensor nodes. Another challenging job is to find the path of the mobile collector in an area with obstacles. In this work, an obstacle aware connectivity establishment (OACE) using mobile nodes in wireless sensor networks is proposed. The mobile robot collects data from each partition and carries forward to other partitions so data finally reaches to sink. To achieve this, a Delaunay triangulation based obstacle avoidance clustering has been performed. The performance of the proposed algorithm has been shown by varying the sensor nodes to a single mobile node and multiple mobile nodes. The number of partitions in the network also plays an important role in network performance. Simulation results show that the proposed method with multiple mobile collectors is more energy-efficient with less latency as compared to the single mobile collector for data collection.

The effects of heavy metals on earthworm population with respect to seasons and distances were investigated on three sampling sites based on their vehicular traffic densities in the northern Nigeria Guinea savanna. Two major highways namely: Zaria-Sokoto (L1) road (about 404km) and Zaria-Kano (L2) road (about 179km) with average traffic densities of 10,720 and 12, 440 cars are the experimental sites. The Ahmadu Bello University Dam road toward Institute of Development Research (IDR) (L3) with an average traffic density of 296 was selected at the reference site. The experimental sites (L1 and L2) are situated in areas with little commercial activities and no residential industrial activities. The site L2 was about 60m away from a petrol filling station. The reference site is situated in an area about 200m away from residential housing and absence of commercial and industrial activities. Soil samples were collected from the three sites at a vertical depth of 0-10m and at perpendicular distances of 0-20m, 20-40m,40-60m,60-70m and 70-80m from the roadway during the dry (February – March) and wet (August – September) season, 2003. Chemical alk;nalysis of soil samples were made at Centre for Energy Research and Training (C.E.R.T) Ahmadu, Bello University, Zaria using the multi-elemental technique Energy dispersive x-ray fluorescence (EDXRF). Pb As, Cd, Cu, Co, Br and Ni were selected for the study. Earthworms were extracted using the formalin expellent method (FEM) and Simple Brine flotation method (SBFM). Soil pH was determined in a 1:2 w/v ratio with distilled water using a Crison Micro pH 2000 pH meter (pH 7.02). The site L3 with the highest heavy metal concentration tends to harbour the highest population of earthworms, which were invariably absence on the two high traffic sites (L1 and L2). Earthworms' populations were variably distributed along the distances from the roadway, and were more abundant in the wet season than in the dry season. Correlation coefficient between the heavy metals and earthworms and between heavy metals and earthworm casts were significant (P=0.05) for the wet season on all the sites. Results of chemical analysis revealed high concentration of heavy metals on the soil of L3, while the soils of L1 and L2 had a lower heavy metal concentrations, Concentrations of the heavy metals decreased with decreasing distances from the roadway (Pb, Br, Cu). The total heavy metal contents (Pb, As, Zn, Co, Ni and Br) were strongly correlated with the soil pH. Combined ANOVA for interaction of distances with seasons and locations were highly significant (P=0.05 and P=0.01). The study concludes that adsorption of the heavy metals by the high organic matter, their persistence in the soil and favourable environmental factors on L3 may have reduced their availability to the earthworms. Then the absence of earthworms on L1 and L2 suggest that the low organic matter and high Cu levels affected their population size.


This work presented the results of experimental studies of influence of volumetric feed rate of ozone-oxygen mixture in the reactor on the pH of the distilled water at a constant ozone concentration. It is shown that maximum pH value of the reaction mixture increases with an increase of the feed rate of ozone-oxygen mixture at a constant maximum value of ozone concentration. In the reaction of ozone with water different oxygen containing anions, cations, radicals and radical anions and protons, including protonated ozone and hydrogen peroxide H 2O 2were formed. The medium of distilled water shifted from neutral to strongly alkaline when passing through a layer of gaseous ozone-oxygen mixture, then gradually returned to weakly acidic.


Determining the natural and forced oscillations of frame structures simulated by the rods with distributed masses (an infinite number of degrees of freedom) is quite difficult. Therefore, in the article, the frame model is endued with a finite number of degrees of freedom: the mass is placed in a certain number of nodes that elastically interact with rods that have no mass. The rods work only for bending. Longitudinal displacements are not taken into account, since the frequency of longitudinal oscillations is two orders of magnitude higher than the frequency of bending ones. Such a model leads to the construction of expressions of the kinetic and potential energy, which then allows using the Lagrange equations of second kind to obtain a system of differential oscillation equations of the structure. The problem of free oscillations of the G-shaped frame was solved in the article using Green's functions, matrices of stiffness, masses, malleability, etc. The obtained approximate results were compared with little-known exact results and demonstrated good convergence, especially with an increase in the number of degrees of freedom (the number of concentrated masses simulating the distributed mass of the rods of the G-shaped frame).


This study aimed to find whether meditation can be effective in terms of post-traumatic stress(PSTD) or not. The purpose of this current study was to analyse the flood victims specifically (IDPs) by the influence of meditation on state post-traumatic stress. Guided meditation is helpful in reduction of the stress. The study analyses how meditation reduces the post-traumatic stress of IDP flood victims. The study is experimental in nature. The survey was conducted from N= 100 participants IDPs by using convenience sampling. SPSS used to quantify the data. The measure used in the research was the 3.7 PTSD checklist civilian version of the flood exposure questionnaire to collect the data from Internally displaced persons. First, for the pre-test, it was provided before the meditation and the second time it was given after the guided meditation for the post-test. The result of the research supports that PTSD can be reduced by meditation.


This study analyses the treatment effects of public training programmes for the unemployed in Germany. Based on propensity score matching methods, we extend the picture that has been sketched in previous studies by estimating the treatment effects of medium-term programmes for different skill and age groups. Our results indicate that programme participation has a positive impact on employment probabilities and earnings for almost all sub-groups. We find little evidence for the presence of heterogeneous treatment effects, and the magnitude of the differences is quite small. Our results thus – at least in part – conflict with the strategy to provide training increasingly to individuals with better employment prospects.


Hazel Kyrk's A Theory of Consumption, published in 1923, not only revealed the limitations of contemporary consumer theory within economics but also proposed a new, more interdisciplinary approach to consumer research. The book attracted little interest at the time of its publication and was subsequently neglected by marketing specialists. It nevertheless foreshadowed many of the developments and new directions in consumer research that have taken place over the past fifty years and deserves some greater recognition as a pioneering study.


In the 1950s for the first time shotcrete was used because an essential support measure to guarantee the stability of an underground opening in Austria, Detzelhofer (1). Since that time the use of shotcrete has proved to be one of the most flexible and effective support measures in rock and soft ground tunnelling. Depending on the geological boundary conditions and on the ground water situation the load bearing behaviour of the shotcrete lining can be divided into 3 characteristic cases, being considerable different in terms of dimensioning of the lining, stresses in the lining and necessity of the lining.


Post-traumatic duodenal hematoma is a rare condition after an abdominal trauma, the diagnostic is difficult because of the retro-pancreatic situation of the duodenum. 70% of duodenal hematomas occur after closed abdominal trauma. The first case of duodenal hematoma was published in 1838 by McLaughlan. The clinical signs are non-specific and vary according to the site of the hematoma in the four portions of the duodenum. The diagnosisis based on imaging, in particular abdominal CT scan, the management has completely changed towards a more conservative strategy by reserving surgery for persistent obstruction and expansion of the hematoma. We report a case of a patient victim of a road traffic accident resulting in a blunt abdominal trauma manifested bysigns of high occlusion whose abdominal CT scan showed the presence of a duodenal hematoma compressing the 3rd portion of the duodenum responsible for gastric and esophageal distension treated by a conservative method.
